If there are multiple columns with identical names, the solutions given here so far will remove all of the columns, which may not be what one is looking for. This may be the case if one is trying to remove duplicate columns except one instance. The example below clarifies this situation:

# make a df with duplicate columns 'x'
df = pd.DataFrame({'x': range(5) , 'x':range(5), 'y':range(6, 11)}, columns = ['x', 'x', 'y']) 


df
Out[495]: 
   x  x   y
0  0  0   6
1  1  1   7
2  2  2   8
3  3  3   9
4  4  4  10

# attempting to drop the first column according to the solution offered so far     
df.drop(df.columns[0], axis = 1) 
   y
0  6
1  7
2  8
3  9
4  10

As you can see, both Xs columns were dropped. Alternative solution:

column_numbers = [x for x in range(df.shape[1])]  # list of columns' integer indices

column_numbers .remove(0) #removing column integer index 0
df.iloc[:, column_numbers] #return all columns except the 0th column

   x  y
0  0  6
1  1  7
2  2  8
3  3  9
4  4  10

As you can see, this truly removed only the 0th column (first 'x').

To find out if a string contains substring you can use the index function:

if (index($str, $substr) != -1) {
    print "$str contains $substr\n";
} 

It will return the position of the first occurrence of $substr in $str, or -1 if the substring is not found.

Hypothetically, if search landed you on this question then you probably want this:

doReturn(someReturn).when(someObject).doSomething(argThat(argument -> argument.getName().equals("Bob")));

Why? Because like me you value time and you are not going to implement .equals just for the sake of the single test scenario.

And 99 % of tests fall apart with null returned from Mock and in a reasonable design you would avoid return null at all costs, use Optional or move to Kotlin. This implies that verify does not need to be used that often and ArgumentCaptors are just too tedious to write.

There's one really important difference which is not mentioned anywhere.

take(1) emits 1, completes, unsubscribes

first() emits 1, completes, but doesn't unsubscribe.

It means that your upstream observable will still be hot after first() which is probably not expected behavior.

UPD: This referes to RxJS 5.2.0. This issue might be already fixed.

Yo could also set labels = FALSE inside axis(...) and print the labels in a separate command with Text. With this option you can rotate the text the text in case you need it

lablist<-as.vector(c(1:10))
axis(1, at=seq(1, 10, by=1), labels = FALSE)
text(seq(1, 10, by=1), par("usr")[3] - 0.2, labels = lablist, srt = 45, pos = 1, xpd = TRUE)

Detailed explanation here

Update: this was fixed in Firefox v35. See the full gist for details.

== how to hide the select arrow in Firefox ==

Just figured out how to do it. The trick is to use a mix of -prefix-appearance, text-indent and text-overflow. It is pure CSS and requires no extra markup.

select {
    -moz-appearance: none;
    text-indent: 0.01px;
    text-overflow: '';
}

Long story short, by pushing it a tiny bit to the right, the overflow gets rid of the arrow. Pretty neat, huh?

More details on this gist I just wrote. Tested on Ubuntu, Mac and Windows, all with recent Firefox versions.

You should pass the reference to request like below

var options = { ... }_x000D_
var req = http.request(options, function(res) {_x000D_
  // Usual stuff: on(data), on(end), chunks, etc..._x000D_
});_x000D_
_x000D_
req.setTimeout(60000, function(){_x000D_
    this.abort();_x000D_
}).bind(req);_x000D_
req.write('something');_x000D_
req.end();

Request error event will get triggered

req.on("error", function(e){_x000D_
       console.log("Request Error : "+JSON.stringify(e));_x000D_
  });

Singletons are handy when you've got a lot code being run when you initialize and object. For example, when you using iBatis when you setup a persistence object it has to read all the configs, parse the maps, make sure its all correct, etc.. before getting to your code.

If you did this every time, performance would be much degraded. Using it in a singleton, you take that hit once and then all subsequent calls don't have to do it.

As a warning - if you're going to use the following (note the milliseconds instead of minutes):

    SELECT DATEADD(ms, DATEDIFF(ms, GETUTCDATE(), GETDATE()), MyTable.UtcColumn) 
    AS ColumnInLocalTime
    FROM MyTable

Keep in mind that the DATEDIFF part will not always return the same number. So don't use it to compare DateTimes down to milliseconds.

long start = System.currentTimeMillis();
counter.countPrimes(1000000);
long end = System.currentTimeMillis();

System.out.println("Took : " + ((end - start) / 1000));

UPDATE

An even more accurate solution would be:

final long start = System.nanoTime();
counter.countPrimes(1000000);
final long end = System.nanoTime();

System.out.println("Took: " + ((end - start) / 1000000) + "ms");
System.out.println("Took: " + (end - start)/ 1000000000 + " seconds");

Just had a simple variant problem... Convert files of typed .flv to .mp3 (yawn).

for file in read `find . *.flv`; do ffmpeg -i ${file} -acodec copy ${file}.mp3;done

recursively find all the Macintosh user flash files and turn them into audio (copy, no transcode) ... it's like the while above, noting that read instead of just 'for file in ' will escape.

Try this

div:nth-child(4n+4)

You can find the execution time in second with a single function.

// ampersand is important thing here
function microSec( & $ms ) {
    if (\floatval( $ms ) == 0) {
        $ms = microtime( true );
    }
    else {
        $originalMs = $ms;
        $ms = 0;
        return microtime( true ) - $originalMs;
    }
}

// you don't have to define $ms variable. just function needs
// it to calculate the difference.
microSec($ms);
sleep(10);
echo microSec($ms) . " seconds"; // 10 seconds

for( $i = 0; $i < 10; $i++) {
    // you can use same variable everytime without assign a value
    microSec($ms);
    sleep(1);
    echo microSec($ms) . " seconds"; // 1 second
}

for( $i = 0; $i < 10; $i++) {
    // also you can use temp or useless variables
    microSec($xyzabc);
    sleep(1);
    echo microSec($xyzabc) . " seconds"; // 1 second
}

It's in this package (Ubuntu 19.04):

  sudo apt install g++-6

In CellContentDoubleClick event fires only when double clicking on cell's content. I used this and works:

    private void dgvUserList_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        MessageBox.Show(e.RowIndex.ToString());
    }

Please replace

app.set('view engin', 'html'); 

with

app.set('view engine', 'ejs');

 $('elements-to-match').click(function(){
        alert("The id is "+ this.id );
    });

no need to wrap it in a jquery object

Use conditional formatting.

You can enter a condition using any cell you like and a format to apply if the formula is true.

Add .eslintrc in the project root.

{
  "globals": {
    "document": true,
    "foo": true,
    "window": true
  }
}

I've spent a day on trying to put all the pieces together, been in hundreds of sites and tutorials, but they all skip trivial steps.

So here's the full guide:

1. Download and install Java JDK (Choose the Java platform)
2. Download and install Android SDK (Installer is recommended)
3. After android SD finishes installing, open SDK Manager under Android SDK Tools (sometimes needs to be opened under admin's privileges)
4. Choose everything and mark Accept All and install.
5. Download and install IntelliJ IDEA (The community edition is free)
6. Wait for all downloads and installations and stuff to finish.

New Project:

1. Run IntelliJ
2. Create a new project (there's a tutorial here)
3. Enter the name, choose Android type.
4. There's a step missing in the tutorial, when you are asked to choose the JDK (before choosing the SDK) you need to choose the Java JDK you've installed earlier. Should be under C:\Program Files\Java\jdk{version}
5. Choose a New platform ( if there's not one selected ) , the SDK platform is the android platform at C:\Program Files\Android\android-sdk-windows.
6. Choose the android version.
7. Now you can write your program.

Compiling:

1. Near the Run button you need to select the drop-down-list, choose Edit Configurations
2. In the Prefer Android Virtual device select the ... button
3. Click on create, give it a name, press OK.
4. Double click the new device to choose it.
5. Press OK.
6. You're ready to run the program.

You can achieve this directly in Xcode:

The very last checkbox, make sure secure is checked .

Or you can do it using code:

Identifies whether the text object should hide the text being entered.

Declaration

optional var secureTextEntry: Bool { get set }

Discussion

This property is set to false by default. Setting this property to true creates a password-style text object, which hides the text being entered.

example:

texfield.secureTextEntry = true

the following procedure worked for me:

• Close VS.
• Run Visual Studio Installer.
• Click on the 'Modify' button under 'Visual Studio Professional 2017'
• In the new window, scroll down and select 'Visual Studio Extension Development' under 'Other Toolsets'.
• Then on the right, if not selected yet, click on 'Class Designer'
• Click on 'Modify' to confirm

There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/

I'm not familiar with postgresql, but in SQL Server or Oracle, using a subquery would work like below (in Oracle, the SELECT 0 would be SELECT 0 FROM DUAL)

SELECT SUM(sub.value)
FROM
( 
  SELECT SUM(columnA) as value FROM my_table
  WHERE columnB = 1
  UNION
  SELECT 0 as value
) sub

Maybe this would work for postgresql too?

You have to use == to compare (or even ===, if you want to compare types). A single = is for assignment.

if (one == 'rock' && two == 'rock') {
    console.log('Tie! Try again!');
}

yourarray.shape or np.shape() or np.ma.shape() returns the shape of your ndarray as a tuple; And you can get the (number of) dimensions of your array using yourarray.ndim or np.ndim(). (i.e. it gives the n of the ndarray since all arrays in NumPy are just n-dimensional arrays (shortly called as ndarrays))

For a 1D array, the shape would be (n,) where n is the number of elements in your array.

For a 2D array, the shape would be (n,m) where n is the number of rows and m is the number of columns in your array.

Please note that in 1D case, the shape would simply be (n, ) instead of what you said as either (1, n) or (n, 1) for row and column vectors respectively.

This is to follow the convention that:

For 1D array, return a shape tuple with only 1 element   (i.e. (n,))
For 2D array, return a shape tuple with only 2 elements (i.e. (n,m))
For 3D array, return a shape tuple with only 3 elements (i.e. (n,m,k))
For 4D array, return a shape tuple with only 4 elements (i.e. (n,m,k,j))

and so on.

Also, please see the example below to see how np.shape() or np.ma.shape() behaves with 1D arrays and scalars:

# sample array
In [10]: u = np.arange(10)

# get its shape
In [11]: np.shape(u)    # u.shape
Out[11]: (10,)

# get array dimension using `np.ndim`
In [12]: np.ndim(u)
Out[12]: 1

In [13]: np.shape(np.mean(u))
Out[13]: ()       # empty tuple (to indicate that a scalar is a 0D array).

# check using `numpy.ndim`
In [14]: np.ndim(np.mean(u))
Out[14]: 0

P.S.: So, the shape tuple is consistent with our understanding of dimensions of space, at least mathematically.

I found this to be a lot easier

from dateutil import relativedelta
relativedelta.relativedelta(end_time,start_time).seconds

Are you running C++ 11? stoi was added in C++ 11, if you're running on an older version use atoi()

This is many years late but since I found the solution I'll post it here. By using maps it is possible to do what was asked:

map $http_host $variable_name {
    hostnames;

    default       /ap/;
    example.com   /api/;
    *.example.org /whatever/;
}

server {
    location $variable_name/test {
        proxy_pass $auth_proxy;
    }
}

If you need to share the same endpoint across multiple servers, you can also reduce the cost by simply defaulting the value:

map "" $variable_name {
    default       /test/;
}

Map can be used to initialise a variable based on the content of a string and can be used inside http scope allowing variables to be global and sharable across servers.

For those using the context menu api, the docs are not immediately clear on how to obtain tab information.

  chrome.contextMenus.onClicked.addListener(function(info, tab) {
    console.log(info);
    return console.log(tab);
  });

https://developer.chrome.com/extensions/contextMenus

This variable can be set using value="${val1}" inside c:set if you have used jquery in your system.

For API 23+ you need to request the read/write permissions even if they are already in your manifest.

// Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
};

/**
 * Checks if the app has permission to write to device storage
 *
 * If the app does not has permission then the user will be prompted to grant permissions
 *
 * @param activity
 */
public static void verifyStoragePermissions(Activity activity) {
    // Check if we have write permission
    int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        // We don't have permission so prompt the user
        ActivityCompat.requestPermissions(
                activity,
                PERMISSIONS_STORAGE,
                REQUEST_EXTERNAL_STORAGE
        );
    }
}

AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Yes it is possible depending on what css you have, you simply just declare the same thing with a different background like this

ul li {
    background: none !important;
}

ul li{
    background: blue !important;
}

But you have to make sure the declaration comes after the first one seeing as it is cascading.

Demo

You can also create a style tag in jQuery like this

$('head').append('<style> #an-element li { background: inherit !important;} </style>');

Demo

You cannot see any changes because it's not inheriting any background but it is overwriting the background: none;

I came up with what I feel is a much better solution allowing:

• no need for 'this._', that/self, weakmaps, symbols etc. Clear and straightforward 'class' code

• private variables and methods are really private and have the correct 'this' binding

• No use of 'this' at all which means clear code that is much less error prone

• public interface is clear and separated from the implementation as a proxy to private methods

• allows easy composition

with this you can do:

function Counter() {_x000D_
  // public interface_x000D_
  const proxy = {_x000D_
    advance,  // advance counter and get new value_x000D_
    reset,    // reset value_x000D_
    value     // get value_x000D_
  }_x000D_
 _x000D_
  // private variables and methods_x000D_
  let count=0;_x000D_
    _x000D_
  function advance() {_x000D_
    return ++count;_x000D_
  }_x000D_
     _x000D_
  function reset(newCount) {_x000D_
    count=(newCount || 0);_x000D_
  }_x000D_
     _x000D_
  function value() {_x000D_
    return count;_x000D_
  }_x000D_
    _x000D_
  return proxy;_x000D_
}_x000D_
     _x000D_
let counter=Counter.New();_x000D_
console.log(counter instanceof Counter); // true_x000D_
counter.reset(100);_x000D_
console.log('Counter next = '+counter.advance()); // 101_x000D_
console.log(Object.getOwnPropertyNames(counter)); // ["advance", "reset", "value"]

You can use CSS gradient - although there are not consistent across browsers so You would have to code it for every one

Like that: CSS3 Transparency + Gradient

Gradient should be more transparent on top or on top right corner (depending on capabilities)

Note that On Error Resume Next is not set globally. You can put your unsafe part of code eg into a function, which will interrupted immediately if error occurs, and call this function from sub containing precedent OERN statement.

ErrCatch()

Sub ErrCatch()
    Dim Res, CurrentStep

    On Error Resume Next

    Res = UnSafeCode(20, CurrentStep)
    MsgBox "ErrStep " & CurrentStep & vbCrLf & Err.Description

End Sub

Function UnSafeCode(Arg, ErrStep)

    ErrStep = 1
    UnSafeCode = 1 / (Arg - 10)

    ErrStep = 2
    UnSafeCode = 1 / (Arg - 20)

    ErrStep = 3
    UnSafeCode = 1 / (Arg - 30)

    ErrStep = 0
End Function

Just type

document.querySelector('video').playbackRate = 1.25;

in JS console of your modern browser.

var objToJson = { };
objToJson.response = response;
response.write(JSON.stringify(objToJson));

If you alert(JSON.stringify(objToJson)) you will get {"response":"value"}

You can also do this with ArgueJS:

function (){
  arguments = __({nodebox: undefined, str: [String: "hai"]})

  // and now on, you can access your arguments by
  //   arguments.nodebox and arguments.str
}

If your compiler supports C++11 standard, there is a constructor inheritance using using (pun intended). For more see Wikipedia C++11 article. You write:

class A
{
    public: 
        explicit A(int x) {}
};

class B: public A
{
     using A::A;
};

This is all or nothing - you cannot inherit only some constructors, if you write this, you inherit all of them. To inherit only selected ones you need to write the individual constructors manually and call the base constructor as needed from them.

Historically constructors could not be inherited in the C++03 standard. You needed to inherit them manually one by one by calling base implementation on your own.

In Spring boot, /META-INF/resources/, /resources/, static/ and public/ directories are available to serve static contents.

So you can create a static/ or public/ directory under resources/ directory and put your static contents there. And they will be accessible by: http://localhost:8080/your-file.ext. (assuming the server.port is 8080)

You can customize these directories using spring.resources.static-locations in the application.properties.

For example:

spring.resources.static-locations=classpath:/custom/

Now you can use custom/ folder under resources/ to serve static files.

Update:

This is also possible using java config:

@Configuration
public class StaticConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/custom/");
    }
}

This confugration maps contents of custom directory to the http://localhost:8080/static/** url.

If the code of the previous posts doesn't work, give this a try:

$("a.ui-dialog-titlebar-close")[0].click();

This can also be done with a timeout:

# Ping until timeout or 1 successful packet
ping -w (timeout) -c 1

Remove all forward slash occurrences with blank char in Javascript.

modelData = modelData.replace(/\//g, '');

Just store the index generated in a variable, and then access the array using this varaible:

int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);

P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.

According to this approach, I will have some variable Random r somewhere, and I will just use:

int idx = r.nextInt(fruits.length)

However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.

You can write complete apps for almost any smartphone platform (Android, iOS,...) using Phonegap. (http://www.phonegap.com)

It is an open source framework that exposes native capabilities to a web view, so that you can do anything a native app can do.

This is very suitable for cross platform development if you're not building something that has to be pixel perfect in every way, or is very hardware intensive.

If you are looking for UI Frameworks that can be used to build such apps, there is a wide range of different libraries. (Like Sencha, jQuery mobile, ...)

And to be a little biased, there is something I built as well: http://www.m-gwt.com

As of June 15, 2015 you may use Set() to create a unique array:

var uniqueArray = [...new Set(array)]

For your Example:

var data = ["X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11"]
var newArray = [...new Set(data)]
console.log(newArray)

>> ["X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11"]

You will figure out that setOnPageChangeListener is deprecated, use addOnPageChangeListener, as below:

ViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
       if(position == 1){  // if you want the second page, for example
           //Your code here
       }
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
});

If your column with DATE datatype has value like below : -

value in column : 10-NOV-2005 06:31:00

Then, You can Use TRUNC function in select query to convert your date-time value to only date like - DD/MM/YYYY or DD-MON-YYYY

select TRUNC(column_1) from table1;

result : 10-NOV-2005

You will see above result - Provided that NLS_DATE_FORMAT is set as like below :-

Alter session NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';

If you can generate the Excel file on the server, that is probably the best way. With Excel you can add formatting and get the output to look better. Several Excel options have already been mentioned. If you have a PHP backend, you might consider phpExcel.

If you are trying to do everything on the client in javascript, I don't think Excel is an option. You could create a CSV file and create a data URL to allow the user to download it.

I created a JSFiddle to demonstrate: http://jsfiddle.net/5KRf6/3/

This javascript (assuming you are using jQuery) will take the values out of input boxes in a table and build a CSV formatted string:

var csv = "";
$("table").find("tr").each(function () {
    var sep = "";
    $(this).find("input").each(function () {
        csv += sep + $(this).val();
        sep = ",";
    });
    csv += "\n";
});

If you wish, you can drop the data into a tag on the page (in my case a tag with an id of "csv"):

$("#csv").text(csv);

You can generate a URL to that text with this code:

window.URL = window.URL || window.webkiURL;
var blob = new Blob([csv]);
var blobURL = window.URL.createObjectURL(blob);

Finally, this will add a link to download that data:

$("#downloadLink").html("");
$("<a></a>").
attr("href", blobURL).
attr("download", "data.csv").
text("Download Data").
appendTo('#downloadLink');

Use the following:

echo $form->field($model, 'hidden1')->hiddenInput(['value'=> $value])->label(false);

You can simply use:

mvn --settings YourOwnSettings.xml clean install

or

mvn -s YourOwnSettings.xml clean install

If you use echo inside an if with other commands, like "read", it might ignore the setting and it will jump to a new line anyway.

MIME type of the CSV is text/csv according to RFC 4180.

Let's say you want to pass a prop to a child component and that prop is a boolean that will determine if the checkbox is checked or not, then you have to pass the boolean value to the v-bind:checked="booleanValue" or the shorter way :checked="booleanValue", for example:

<input
    id="checkbox"
    type="checkbox"
    :value="checkboxVal"
    :checked="booleanValue"
    v-on:input="checkboxVal = $event.target.value"

That should work and the checkbox will display the checkbox with it's current boolean state (if true checked, if not unchecked).

I think I would create a class but another alternative is output parameters.

public void GetOrderRelatedIds(out int OrderGroupId, out int OrderTypeId, out int OrderSubTypeId, out int OrderRequirementId)

Since your Tuple only contains integers you could represent it with a Dictionary<string,int>

var orderIds = new Dictionary<string, int> {
    {"OrderGroupId", 1},
    {"OrderTypeId", 2},
    {"OrderSubTypeId", 3},
    {"OrderRequirementId", 4}.
};

but I don't recommend that either.

I came across an interesting link that make a distinction between gross, systematic, random errors.

Client-Side validation suits perfectly for preventing gross and random errors. Typically a max length for texture and input. Do not mimic the server-side validation rule; provide your own gross, rule of thumb validation rule (ex. 200 characters on client-side; n on server-side dictated by a strong business rule).

Server-side validation suits perfectly for preventing systematic errors; it will enforce business rules.

In a project I'm involved in, the validation is done on the server through ajax requests. On the client I display error messages accordingly.

Further reading: gross, systematic, random errors:

It's better to use the Hamcrest for negative assertions rather than assertFalse as in the former the test report will show a diff for the assertion failure.

If you use assertFalse, you just get an assertion failure in the report. i.e. lost information on cause of the failure.

Seems M$ is using JSON Web Token (JWT) to wrap in license data. I guess inside CertificateBytes will be somehow the payload - you're email and other details.

So far for the rough overview what's the data inside.

For more wishes get ILSpy + Reflexil (<- to changes/correct little things!) and then 'browser&correct' files like c:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE**Microsoft.VisualStudio.Licensing.dll** or check out 'Microsoft.VisualStudio.Services.WebApi.dll'

1. Due to the way that strings are stored in Perl, getting the length of a string is optimized.
   if (length $str) is a good way of checking that a string is non-empty.

2. If you're in a situation where you haven't already guarded against undef, then the catch-all for "non-empty" that won't warn is if (defined $str and length $str).

In Ruby on Rails I used this code, and it works perfectly:

req_profilepic = ActiveSupport::JSON.decode(open(URI.encode("https://graph.facebook.com/me/?fields=picture&type=large&access_token=#{fb_access_token}")))

profilepic_url = req_profilepic['picture']

You need something like this, maybe it can be improved. This is a first attempt:

...
import org.springframework.core.env.PropertySource;
import org.springframework.core.env.AbstractEnvironment;
import org.springframework.core.env.Environment;
import org.springframework.core.env.MapPropertySource;
...

@Configuration
...
@org.springframework.context.annotation.PropertySource("classpath:/config/default.properties")
...
public class GeneralApplicationConfiguration implements WebApplicationInitializer 
{
    @Autowired
    Environment env;

    public void someMethod() {
        ...
        Map<String, Object> map = new HashMap();
        for(Iterator it = ((AbstractEnvironment) env).getPropertySources().iterator(); it.hasNext(); ) {
            PropertySource propertySource = (PropertySource) it.next();
            if (propertySource instanceof MapPropertySource) {
                map.putAll(((MapPropertySource) propertySource).getSource());
            }
        }
        ...
    }
...

Basically, everything from the Environment that's a MapPropertySource (and there are quite a lot of implementations) can be accessed as a Map of properties.

for me this error was actually caused by a field falsely declared as public instead of private.

Simple workaround - just use hidden field as placeholder for select, checkbox and radio.

From this code to -

<form action="/Media/Add">
    <input type="hidden" name="Id" value="123" />

    <!-- this does not appear in request -->
    <input type="textbox" name="Percentage" value="100" disabled="disabled" /> 
    <select name="gender" disabled="disabled">
          <option value="male">Male</option>
          <option value="female" selected>Female</option>
    </select>

</form>

that code -

<form action="/Media/Add">
    <input type="hidden" name="Id" value="123" />

    <input type="textbox" value="100" readonly /> 

    <input type="hidden" name="gender" value="female" />
    <select name="gender" disabled="disabled">
          <option value="male">Male</option>
          <option value="female" selected>Female</option>
    </select>
</form>

You haven't provided any of your code from LightFactoryRemote, so this is only a presumption, but it looks like the kind of problem you'd be seeing if you were using the bindService method on it's own.

To ensure a service is kept running, even after the activity that started it has had its onDestroy method called, you should first use startService.

The android docs for startService state:

Using startService() overrides the default service lifetime that is managed by bindService(Intent, ServiceConnection, int): it requires the service to remain running until stopService(Intent) is called, regardless of whether any clients are connected to it.

Whereas for bindService:

The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.

So what's happened is the activity that bound (and therefore started) the service, has been stopped and thus the system thinks the service is no longer required and causes that error (and then probably stops the service).

Example

In this example the service should be kept running regardless of whether the calling activity is running.

ComponentName myService = startService(new Intent(this, myClass.class));
bindService(new Intent(this, myClass.class), myServiceConn, BIND_AUTO_CREATE);

The first line starts the service, and the second binds it to the activity.

Latest and greatest way to do this:

Node supports file and buffer operations with the base64 encoding:

const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});

Or using the new promises API:

const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});

I needed same thing and this solution work fine, hope it can help someone also

Enumeration[] array = Enumeration.values();
List<Enumeration> list = Arrays.asList(array);

then you can get the .name() of your enumeration.

You can't make a JPEG image transparent. You should use a format that allows transparency, like GIF or PNG.

Paint will open these files, but AFAIK it'll erase transparency if you edit the file. Use some other application like Paint.NET (it's free).

Edit: since other people have mentioned it: you can convert JPEG images into PNG, in any editor that's capable of working with both types.

What type is the collection? If it's List, you can use the helpful "RemoveAll":

int cnt = workspace.RoleAssignments
                      .RemoveAll(spa => spa.Member.Name == shortName)

(This works in .NET 2.0. Of course, if you don't have the newer compiler, you'll have to use "delegate (SPRoleAssignment spa) { return spa.Member.Name == shortName; }" instead of the nice lambda syntax.)

Another approach if it's not a List, but still an ICollection:

   var toRemove = workspace.RoleAssignments
                              .FirstOrDefault(spa => spa.Member.Name == shortName)
   if (toRemove != null) workspace.RoleAssignments.Remove(toRemove);

This requires the Enumerable extension methods. (You can copy the Mono ones in, if you are stuck on .NET 2.0). If it's some custom collection that cannot take an item, but MUST take an index, some of the other Enumerable methods, such as Select, pass in the integer index for you.

I had the problem not in my C# model, but in the javascript object I was posting using AJAX. I'm using Angular for binding and had a capitalized Notes field on the page while my C# object was expecting lower-case notes. A more descriptive error would sure be nice.

C#:

class Post {
    public string notes { get; set; }
}

Angular/Javascript:

<input ng-model="post.Notes" type="text">

I know this is a fairly old question, but I was searching for a solution to generically deserialize nested JSON to a Map<String, Object>, and found nothing.

The way my yaml deserializer works, it defaults JSON objects to Map<String, Object> when you don't specify a type, but gson doesn't seem to do this. Luckily you can accomplish it with a custom deserializer.

I used the following deserializer to naturally deserialize anything, defaulting JsonObjects to Map<String, Object> and JsonArrays to Object[]s, where all the children are similarly deserialized.

private static class NaturalDeserializer implements JsonDeserializer<Object> {
  public Object deserialize(JsonElement json, Type typeOfT, 
      JsonDeserializationContext context) {
    if(json.isJsonNull()) return null;
    else if(json.isJsonPrimitive()) return handlePrimitive(json.getAsJsonPrimitive());
    else if(json.isJsonArray()) return handleArray(json.getAsJsonArray(), context);
    else return handleObject(json.getAsJsonObject(), context);
  }
  private Object handlePrimitive(JsonPrimitive json) {
    if(json.isBoolean())
      return json.getAsBoolean();
    else if(json.isString())
      return json.getAsString();
    else {
      BigDecimal bigDec = json.getAsBigDecimal();
      // Find out if it is an int type
      try {
        bigDec.toBigIntegerExact();
        try { return bigDec.intValueExact(); }
        catch(ArithmeticException e) {}
        return bigDec.longValue();
      } catch(ArithmeticException e) {}
      // Just return it as a double
      return bigDec.doubleValue();
    }
  }
  private Object handleArray(JsonArray json, JsonDeserializationContext context) {
    Object[] array = new Object[json.size()];
    for(int i = 0; i < array.length; i++)
      array[i] = context.deserialize(json.get(i), Object.class);
    return array;
  }
  private Object handleObject(JsonObject json, JsonDeserializationContext context) {
    Map<String, Object> map = new HashMap<String, Object>();
    for(Map.Entry<String, JsonElement> entry : json.entrySet())
      map.put(entry.getKey(), context.deserialize(entry.getValue(), Object.class));
    return map;
  }
}

The messiness inside the handlePrimitive method is for making sure you only ever get a Double or an Integer or a Long, and probably could be better, or at least simplified if you're okay with getting BigDecimals, which I believe is the default.

You can register this adapter like:

GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.registerTypeAdapter(Object.class, new NaturalDeserializer());
Gson gson = gsonBuilder.create();

And then call it like:

Object natural = gson.fromJson(source, Object.class);

I'm not sure why this is not the default behavior in gson, since it is in most other semi-structured serialization libraries...

"Clean Solution" followed by "Rebuild Solution" seems to fix it as well.

You can try this:

#!/bin/sh
nohup java -jar /web/server.jar &

The & symbol, switches the program to run in the background.

The nohup utility makes the command passed as an argument run in the background even after you log out.

The -A option adds, modifies, and removes index entries to match the working tree.

In Git 2 the -A option is now the default.

When a . is added that limits the scope of the update to the directory you are currently in, as per the Git documentation

If no <pathspec> is given when -A option is used, all files in the entire working tree are updated (old versions of Git used to limit the update to the current directory and its subdirectories).

One thing that I would add is that if the --interactive or -p mode is used then git add will behave as if the update (-u) flag was used and not add new files.

This one is good example for Swift 4 about async:

DispatchQueue.global(qos: .background).async {
    // Background Thread
    DispatchQueue.main.async {
        // Run UI Updates or call completion block
    }
}

I recently came to a similar situation where I needed to register a handler for an event only once. I found that you can safely unregister first, and then register again, even if the handler is not registered at all:

myClass.MyEvent -= MyHandler;
myClass.MyEvent += MyHandler;

Note that doing this every time you register your handler will ensure that your handler is registered only once. Sounds like a pretty good practice to me :)

You can try: Using the --authenticationDatabase flag helps.

mongo --port 27017 -u "admin" -p "password" --authenticationDatabase "admin"

With two capturing groups would have been also possible; I would have also included two dashes, as additional left and right boundaries, before and after the digits, and the modified expression would have looked like:

(.*name=".+_)\d+(_[^"]+".*)

const regex = /(.*name=".+_)\d+(_[^"]+".*)/g;_x000D_
const str = `some_data_before name="some_text_0_some_text" and then some_data after`;_x000D_
const subst = `$1!NEW_ID!$2`;_x000D_
const result = str.replace(regex, subst);_x000D_
console.log(result);

If you wish to explore/simplify/modify the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

RegEx Circuit

jex.im visualizes regular expressions:

For reasonably modern versions of sed, edit the standard input to yield the standard output with

$ echo 't???? ß?ß??? ?? ??p??' | sed -E -e 's/[[:blank:]]+/\n/g'
t????
ß?ß???
??
??p??

If your vocabulary words are in files named lesson1 and lesson2, redirect sed’s standard output to the file all-vocab with

sed -E -e 's/[[:blank:]]+/\n/g' lesson1 lesson2 > all-vocab

What it means:

• The character class [[:blank:]] matches either a single space character or a single tab character.
  • Use [[:space:]] instead to match any single whitespace character (commonly space, tab, newline, carriage return, form-feed, and vertical tab).
  • The + quantifier means match one or more of the previous pattern.
  • So [[:blank:]]+ is a sequence of one or more characters that are all space or tab.
• The \n in the replacement is the newline that you want.
• The /g modifier on the end means perform the substitution as many times as possible rather than just once.
• The -E option tells sed to use POSIX extended regex syntax and in particular for this case the + quantifier. Without -E, your sed command becomes sed -e 's/[[:blank:]]\+/\n/g'. (Note the use of \+ rather than simple +.)

Perl Compatible Regexes

For those familiar with Perl-compatible regexes and a PCRE-capable sed, use \s+ to match runs of at least one whitespace character, as in

sed -E -e 's/\s+/\n/g' old > new

or

sed -e 's/\s\+/\n/g' old > new

These commands read input from the file old and write the result to a file named new in the current directory.

Maximum portability, maximum cruftiness

Going back to almost any version of sed since Version 7 Unix, the command invocation is a bit more baroque.

$ echo 't???? ß?ß??? ?? ??p??' | sed -e 's/[ \t][ \t]*/\
/g'
t????
ß?ß???
??
??p??

Notes:

• Here we do not even assume the existence of the humble + quantifier and simulate it with a single space-or-tab ([ \t]) followed by zero or more of them ([ \t]*).
• Similarly, assuming sed does not understand \n for newline, we have to include it on the command line verbatim.
  • The \ and the end of the first line of the command is a continuation marker that escapes the immediately following newline, and the remainder of the command is on the next line.
    • Note: There must be no whitespace preceding the escaped newline. That is, the end of the first line must be exactly backslash followed by end-of-line.
  • This error prone process helps one appreciate why the world moved to visible characters, and you will want to exercise some care in trying out the command with copy-and-paste.

Note on backslashes and quoting

The commands above all used single quotes ('') rather than double quotes (""). Consider:

$ echo '\\\\' "\\\\"
\\\\ \\

That is, the shell applies different escaping rules to single-quoted strings as compared with double-quoted strings. You typically want to protect all the backslashes common in regexes with single quotes.

Java 8 Time API:

Instant now = Instant.now(); //current date
Instant before = now.minus(Duration.ofDays(300));
Date dateBefore = Date.from(before);

One point I noticed with Primefaces 3.4 and Netbeans 7.2:

Remove the Netbeans auto-filled parameters for function handleFileUpload i.e. (event) otherwise event could be null.

<h:form>
    <p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload(event)}"
        mode="advanced" 
        update="messages"
        sizeLimit="100000" 
        allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>

    <p:growl id="messages" showDetail="true"/>
</h:form>

You could try something like this as well

<a href="#" onclick="one(); two();" >click</a>

<script type="text/javascript">
    function one(){
        alert('test');
    }

    function two(){
        alert('test2');
    }
</script>

In command line prompt:

set __COMPAT_LAYER=RUNASINVOKER
SystemPropertiesAdvanced.exe

Now you can set user environment variables.

In a .java file,there can be only one public top-level class whose name is the same as the file, but there might be several public inner classes which can be exported to everyone and access the outer class's fields/methods,for example:AlertDialog.Builder(modified by 'public static') in AlertDialog(modified by 'public')

I often use this:

function deepCopy(obj) {
    if(typeof obj !== 'object' || obj === null) {
        return obj;
    }

    if(obj instanceof Date) {
        return new Date(obj.getTime());
    }

    if(obj instanceof Array) {
        return obj.reduce((arr, item, i) => {
            arr[i] = deepCopy(item);
            return arr;
        }, []);
    }

    if(obj instanceof Object) {
        return Object.keys(obj).reduce((newObj, key) => {
            newObj[key] = deepCopy(obj[key]);
            return newObj;
        }, {})
    }
}

It turns out this can be nicely expressed in a vectorized fashion:

> df = pd.DataFrame({'a':[0,0,1,1], 'b':[0,1,0,1]})
> df = df[(df.T != 0).any()]
> df
   a  b
1  0  1
2  1  0
3  1  1

For those who came here looking for a way to take pictures/photos programmatically using both Android's Camera and Camera2 API, take a look at the open source sample provided by Google itself here.

I used the below. The genre element will start where the DJ element ends,

<div>
<div style="width:50%; float:left">DJ</div>
<div>genre</div>
</div>

pardon the inline css.

You can link directly with Media Fragments URI, just change the filename to file.webm#t=50

Here's an example

This is pretty cool, you can do all sorts of things. But I don't know the current state of browser support.

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

You can also write like below (without pyspark.sql.functions):

df.filter('d<5 and (col1 <> col3 or (col1 = col3 and col2 <> col4))').show()

Result:

+----+----+----+----+---+
|col1|col2|col3|col4|  d|
+----+----+----+----+---+
|   A|  xx|   D|  vv|  4|
|   A|   x|   A|  xx|  3|
|   E| xxx|   B|  vv|  3|
|   F|xxxx|   F| vvv|  4|
|   G| xxx|   G|  xx|  4|
+----+----+----+----+---+

You need to use

 $rootScope.$broadcast()

in the controller that must send datas. And in the one that receive those datas, you use

 $scope.$on

As of Feb 2018, fetch() can be cancelled with the code below on Chrome (read Using Readable Streams to enable Firefox support). No error is thrown for catch() to pick up, and this is a temporary solution until AbortController is fully adopted.

fetch('YOUR_CUSTOM_URL')
.then(response => {
  if (!response.body) {
    console.warn("ReadableStream is not yet supported in this browser.  See https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream")
    return response;
  }

  // get reference to ReadableStream so we can cancel/abort this fetch request.
  const responseReader = response.body.getReader();
  startAbortSimulation(responseReader);

  // Return a new Response object that implements a custom reader.
  return new Response(new ReadableStream(new ReadableStreamConfig(responseReader)));
})
.then(response => response.blob())
.then(data => console.log('Download ended. Bytes downloaded:', data.size))
.catch(error => console.error('Error during fetch()', error))


// Here's an example of how to abort request once fetch() starts
function startAbortSimulation(responseReader) {
  // abort fetch() after 50ms
  setTimeout(function() {
    console.log('aborting fetch()...');
    responseReader.cancel()
    .then(function() {
      console.log('fetch() aborted');
    })
  },50)
}


// ReadableStream constructor requires custom implementation of start() method
function ReadableStreamConfig(reader) {
  return {
    start(controller) {
      read();
      function read() {
        reader.read().then(({done,value}) => {
          if (done) {
            controller.close();
            return;
          }
          controller.enqueue(value);
          read();
        })
      }
    }
  }
}

Why

There is IMHO a good reason why Composer will use the --dev flag by default (on install and update) nowadays. Composer is mostly run in scenario's where this is desired behavior:

The basic Composer workflow is as follows:

• A new project is started: composer.phar install --dev, json and lock files are commited to VCS.
• Other developers start working on the project: checkout of VCS and composer.phar install --dev.
• A developer adds dependancies: composer.phar require <package>, add --dev if you want the package in the require-dev section (and commit).
• Others go along: (checkout and) composer.phar install --dev.
• A developer wants newer versions of dependencies: composer.phar update --dev <package> (and commit).
• Others go along: (checkout and) composer.phar install --dev.
• Project is deployed: composer.phar install --no-dev

As you can see the --dev flag is used (far) more than the --no-dev flag, especially when the number of developers working on the project grows.

Production deploy

What's the correct way to deploy this without installing the "dev" dependencies?

Well, the composer.json and composer.lock file should be committed to VCS. Don't omit composer.lock because it contains important information on package-versions that should be used.

When performing a production deploy, you can pass the --no-dev flag to Composer:

composer.phar install --no-dev

The composer.lock file might contain information about dev-packages. This doesn't matter. The --no-dev flag will make sure those dev-packages are not installed.

When I say "production deploy", I mean a deploy that's aimed at being used in production. I'm not arguing whether a composer.phar install should be done on a production server, or on a staging server where things can be reviewed. That is not the scope of this answer. I'm merely pointing out how to composer.phar install without installing "dev" dependencies.

Offtopic

The --optimize-autoloader flag might also be desirable on production (it generates a class-map which will speed up autoloading in your application):

composer.phar install --no-dev --optimize-autoloader

Or when automated deployment is done:

composer.phar install --no-ansi --no-dev --no-interaction --no-plugins --no-progress --no-scripts --optimize-autoloader

If your codebase supports it, you could swap out --optimize-autoloader for --classmap-authoritative. More info here

I've used mingw on Linux to make Windows executables in C, I suspect C++ would work as well.

I have a project, ELLCC, that packages clang and other things as a cross compiler tool chain. I use it to compile clang (C++), binutils, and GDB for Windows. Follow the download link at ellcc.org for pre-compiled binaries for several Linux hosts.

As seen in Gradle (Eclipse plugin)

http://www.gradle.org/get-started

Gradle uses whichever JDK it finds in your path (to check, use java -version). Alternatively, you can set the JAVA_HOME environment variable to point to the install directory of the desired JDK.

If you are using this Eclipse plugin or Enide Studio 2014, alternative JAVA_HOME to use (set in Preferences) will be in version 0.15, see http://www.nodeclipse.org/history

While playing around with the answers I found here to become familiar with it I twisted Nuoji's solution a bit so that I could understand it faster when looking at it in the future.

public static String stringToBinary(String str, boolean pad ) {
    byte[] bytes = str.getBytes();
    StringBuilder binary = new StringBuilder();
    for (byte b : bytes)
    {
       binary.append(Integer.toBinaryString((int) b));
       if(pad) { binary.append(' '); }
    }
    return binary.toString();        
}

TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

To restart the service:

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart        # typical
/etc/init.d/php5-fpm restart       # debian-style
/etc/init.d/php7.0-fpm restart     # debian-style PHP 7

Using service wrapper script

service php-fpm restart        # typical
service php5-fpm restart       # debian-style
service php7.0-fpm restart.    # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service        # typical
systemctl restart php5-fpm.service       # uncommon
systemctl restart php7.0-fpm.service     # uncommon PHP 7

Or whatever the equivalent is on your system.

The above commands taken directly from this server fault answer

Use off() method after click event is triggered to disable element for the further click.

$('#clickElement').off('click');

You need to log in with the correct username and password. Does the user root have permission to access the database? or did you create a specific user to do this?

The other issue might be that you are not using a password when trying to log in.

Another way of doing the same could be using the Gson Class

String filename = "path/to/file/abc.json";
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
SampleClass data = gson.fromJson(reader, SampleClass.class);

This will give an object obtained after parsing the json string to work with.

To kill the puma process first run

    lsof -wni tcp:3000 

to show what is using port 3000. Then use the PID that comes with the result to run the kill process.

For example after running lsof -wni tcp:3000 you might get something like

    COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
    ruby    3366 dummy    8u  IPv4  16901      0t0  TCP 127.0.0.1:3000 (LISTEN)

Now run the following to kill the process. (where 3366 is the PID)

kill -9 3366

Should resolve the issue

No, there is no way to do this with git show. But it would certainly be nice sometimes, and it would probably be relatively easy to implement in the git source code (after all, you just have to tell it to not trim out what it thinks is extraneous output), so the patch to do so would probably be accepted by the git maintainers.

Be careful what you wish for, though; merging a branch with a one-line change that was forked three months ago will still have a huge diff versus the mainline, and so such a full diff would be almost completely unhelpful. That's why git doesn't show it.

try this:

HTML:

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div>
</div>

CSS:

.container {
  width: 200px;
  height: 100px;
  display: flex;
  overflow-x: auto;
}

.item {
  width: 100px;
  flex-shrink: 0;
  height: 100px;
}

I had this problem in windows. Most of the answers are not as recommended by anaconda, you should not add the path to the environment variables as it can break other things. Instead you should use anaconda prompt as mentioned in the top answer.

However, this may also break. In this case right click on the shortcut, go to shortcut tab, and the target value should read something like:

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

Get the Method Names:

var getMethodNames = function (obj) {
    return (Object.getOwnPropertyNames(obj).filter(function (key) {
        return obj[key] && (typeof obj[key] === "function");
    }));
};

Or, Get the Methods:

var getMethods     = function (obj) {
    return (Object.getOwnPropertyNames(obj).filter(function (key) {
        return obj[key] && (typeof obj[key] === "function");
    })).map(function (key) {
        return obj[key];
    });
};

You have to create your own ControlTemplate for the Button. just have a look at the sample

<Style x:Key="RoundCorner" TargetType="{x:Type Button}">
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Padding" Value="1"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid x:Name="grid">
                    <Border x:Name="border" CornerRadius="8" BorderBrush="Black" BorderThickness="2">
                        <Border.Background>

Using

<Button Style="{DynamicResource RoundCorner}" 
        Height="25" 
        VerticalAlignment="Top" 
        Content="Show" 
        Width="100" 
        Margin="5" />

See my fiddle.

You would need to use the border width property and the padding property. I added some animation to make it look cooler:

body{_x000D_
  background-color:lightgreen;_x000D_
}_x000D_
a{_x000D_
  text-decoration:none;_x000D_
  color:green;_x000D_
  border-style:solid;_x000D_
  border-width: 0px 0px 1px 0px;_x000D_
  transition: all .2s ease-in;_x000D_
}_x000D_
_x000D_
a:hover{_x000D_
  color:darkblue;_x000D_
  border-style:solid;_x000D_
  border-width: 0px 0px 1px 0px;_x000D_
  padding:2px;_x000D_
}

I have solved a similar problem using external native lib dependencies that are packaged inside of jar files. Sometimes these architecture dependend libraries are packaged alltogether inside one jar, sometimes they are split up into several jar files. so i wrote some buildscript to scan the jar dependencies for native libs and sort them into the correct android lib folders. Additionally this also provides a way to download dependencies that not found in maven repos which is currently usefull to get JNA working on android because not all native jars are published in public maven repos.

In HTML:

<a href="index.php?link=home" name="home">home</a>

Then in PHP:

if(isset($_GET['link'])){$_SESSION['link'] = $_GET['link'];}

$('#input').on("input",function () {alert('changed');});

works for me.

From Java 9 there is some optimizations in replace method.

In Java 8 it uses a regex.

public String replace(CharSequence target, CharSequence replacement) {
    return Pattern.compile(target.toString(), Pattern.LITERAL).matcher(
            this).replaceAll(Matcher.quoteReplacement(replacement.toString()));
}

From Java 9 and on.

And Stringlatin implementation.

Which perform way better.

You should use

android:windowSoftInputMode="adjustPan|stateHidden"

in your AndroidManifest.xml file where you are declaring your activity. This will adjust your layout contents, when keyboard is shown in the layout.

Split using a regular expression. Note I made the case more general with leading spaces. The list comprehension is to remove the null strings at the front and back.

>>> import re
>>> string = "  blah, lots  ,  of ,  spaces, here "
>>> pattern = re.compile("^\s+|\s*,\s*|\s+$")
>>> print([x for x in pattern.split(string) if x])
['blah', 'lots', 'of', 'spaces', 'here']

This works even if ^\s+ doesn't match:

>>> string = "foo,   bar  "
>>> print([x for x in pattern.split(string) if x])
['foo', 'bar']
>>>

Here's why you need ^\s+:

>>> pattern = re.compile("\s*,\s*|\s+$")
>>> print([x for x in pattern.split(string) if x])
['  blah', 'lots', 'of', 'spaces', 'here']

See the leading spaces in blah?

Clarification: above uses the Python 3 interpreter, but results are the same in Python 2.

Short answer: While it's technically possible to send 100k e-mails each week yourself, the simplest, easiest and cheapest solution is to outsource this to one of the companies that specialize in it (I did say "cheapest": there's no limit to the amount of development time (and therefore money) that you can sink into this when trying to DIY).

Long answer: If you decide that you absolutely want to do this yourself, prepare for a world of hurt (after all, this is e-mail/e-fail we're talking about). You'll need:

• e-mail content that is not spam (otherwise you'll run into additional major roadblocks on every step, even legal repercussions)
• in addition, your content should be easy to distinguish from spam - that may be a bit hard to do in some cases (I heard that a certain pharmaceutical company had to all but abandon e-mail, as their brand names are quite common in spams)
• a configurable SMTP server of your own, one which won't buckle when you dump 100k e-mails onto it (your ISP's upstream server won't be sufficient here and you'll make the ISP violently unhappy; we used two dedicated boxes)
• some mail wrapper (e.g. PhpMailer if PHP's your poison of choice; using PHP's mail() is horrible enough by itself)
• your own sender function to run in a loop, create the mails and pass them to the wrapper (note that you may run into PHP's memory limits if your app has a memory leak; you may need to recycle the sending process periodically, or even better, decouple the "creating e-mails" and "sending e-mails" altogether)

Surprisingly, that was the easy part. The hard part is actually sending it:

• some servers will ban you when you send too many mails close together, so you need to shuffle and watch your queue (e.g. send one mail to [email protected], then three to other domains, only then another to [email protected])
• you need to have correct PTR, SPF, DKIM records
• handling remote server timeouts, misconfigured DNS records and other network pleasantries
• handling invalid e-mails (and no, regex is the wrong tool for that)
• handling unsubscriptions (many legitimate newsletters have been reclassified as spam due to many frustrated users who couldn't unsubscribe in one step and instead chose to "mark as spam" - the spam filters do learn, esp. with large e-mail providers)
• handling bounces and rejects ("no such mailbox [email protected]","mailbox [email protected] full")
• handling blacklisting and removal from blacklists (Sure, you're not sending spam. Some recipients won't be so sure - with such large list, it will happen sometimes, no matter what precautions you take. Some people (e.g. your not-so-scrupulous competitors) might even go as far to falsely report your mailings as spam - it does happen. On average, it takes weeks to get yourself removed from a blacklist.)

And to top it off, you'll have to manage the legal part of it (various federal, state, and local laws; and even different tangles of laws once you send outside the U.S. (note: you have no way of finding if [email protected] lives in Southwest Elbonia, the country with world's most draconian antispam laws)).

I'm pretty sure I missed a few heads of this hydra - are you still sure you want to do this yourself? If so, there'll be another wave, this time merely the annoying problems inherent in sending an e-mail. (You see, SMTP is a store-and-forward protocol, which means that your e-mail will be shuffled across many SMTP servers around the Internet, in the hope that the next one is a bit closer to the final recipient. Basically, the e-mail is sent to an SMTP server, which puts it into its forward queue; when time comes, it will forward it further to a different SMTP server, until it reaches the SMTP server for the given domain. This forward could happen immediately, or in a few minutes, or hours, or days, or never.) Thus, you'll see the following issues - most of which could happen en route as well as at the destination:

• the remote SMTP servers don't want to talk to your SMTP server
• your mails are getting marked as spam (<blink> is not your friend here, nor is <font color=...>)
• your mails are delivered days, even weeks late (contrary to popular opinion, SMTP is designed to make a best effort to deliver the message sometime in the future - not to deliver it now)
• your mails are not delivered at all (already sent from e-mail server on hop #4, not sent yet from server on hop #5, the server that currently holds the message crashes, data is lost)
• your mails are mangled by some braindead server en route (this one is somewhat solvable with base64 encoding, but then the size goes up and the e-mail looks more suspicious)
• your mails are delivered and the recipients seem not to want them ("I'm sure I didn't sign up for this, I remember exactly what I did a year ago" (of course you do, sir))
• users with various versions of Microsoft Outlook and its special handling of Internet mail
• wizard's apprentice mode (a self-reinforcing positive feedback loop - in other words, automated e-mails as replies to automated e-mails as replies to...; you really don't want to be the one to set this off, as you'd anger half the internet at yourself)

and it'll be your job to troubleshoot and solve this (hint: you can't, mostly). The people who run a legit mass-mailing businesses know that in the end you can't solve it, and that they can't solve it either - and they have the reasons well researched, documented and outlined (maybe even as a Powerpoint presentation - complete with sounds and cool transitions - that your bosses can understand), as they've had to explain this a million times before. Plus, for the problems that are actually solvable, they know very well how to solve them.

If, after all this, you are not discouraged and still want to do this, go right ahead: it's even possible that you'll find a better way to do this. Just know that the road ahead won't be easy - sending e-mail is trivial, getting it delivered is hard.

I've found this answer in the site https://plainjs.com/javascript/styles/set-and-get-css-styles-of-elements-53/.

In this code we add multiple styles in an element:

let_x000D_
    element = document.querySelector('span')_x000D_
  , cssStyle = (el, styles) => {_x000D_
      for (var property in styles) {_x000D_
          el.style[property] = styles[property];_x000D_
      }_x000D_
  }_x000D_
;_x000D_
_x000D_
cssStyle(element, { background:'tomato', color: 'white', padding: '0.5rem 1rem'});

span{_x000D_
font-family: sans-serif;_x000D_
color: #323232;_x000D_
background: #fff;_x000D_
}

<span>_x000D_
lorem ipsum_x000D_
</span>

Converting Current DateTime in UTC:

DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");

DateTimeZone dateTimeZone = DateTimeZone.getDefault(); //Default Time Zone

DateTime currDateTime = new DateTime(); //Current DateTime

long utcTime = dateTimeZone.convertLocalToUTC(currDateTime .getMillis(), false);

String currTime = formatter.print(utcTime); //UTC time converted to string from long in format of formatter

currDateTime = formatter.parseDateTime(currTime); //Converted to DateTime in UTC

Just in case, you might have had unbalanced brackets, you can likely design some expression with recursion similar to,

\[(([^\]\[]+)|(?R))*+\]

which of course, it would relate to the language or RegEx engine that you might be using.

RegEx Demo 1

Other than that,

\[([^\]\[\r\n]*)\]

RegEx Demo 2

or,

(?<=\[)[^\]\[\r\n]*(?=\])

RegEx Demo 3

are good options to explore.

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

RegEx Circuit

jex.im visualizes regular expressions:

Test

const regex = /\[([^\]\[\r\n]*)\]/gm;_x000D_
const str = `This is a [sample] string with [some] special words. [another one]_x000D_
This is a [sample string with [some special words. [another one_x000D_
This is a [sample[sample]] string with [[some][some]] special words. [[another one]]`;_x000D_
let m;_x000D_
_x000D_
while ((m = regex.exec(str)) !== null) {_x000D_
    // This is necessary to avoid infinite loops with zero-width matches_x000D_
    if (m.index === regex.lastIndex) {_x000D_
        regex.lastIndex++;_x000D_
    }_x000D_
    _x000D_
    // The result can be accessed through the `m`-variable._x000D_
    m.forEach((match, groupIndex) => {_x000D_
        console.log(`Found match, group ${groupIndex}: ${match}`);_x000D_
    });_x000D_

Regular expression to match balanced parentheses

If you want to work with JAX-RS (e.g. RESTEasy) try this:

@Path("/pic")
public Response get(@QueryParam("url") final String url) {
    String picUrl = URLDecoder.decode(url, "UTF-8");

    return Response.ok(sendPicAsStream(picUrl))
            .header(HttpHeaders.CONTENT_TYPE, "image/jpg")
            .build();
}

private StreamingOutput sendPicAsStream(String picUrl) {
    return output -> {
        try (InputStream is = (new URL(picUrl)).openStream()) {
            ByteStreams.copy(is, output);
        }
    };
}

using javax.ws.rs.core.Response and com.google.common.io.ByteStreams

simple example

<?php
echo '#start main# ';
function a(){
    echo '{start[';
    for($i=1; $i<=9; $i++)
        yield $i;
    echo ']end} ';
}
foreach(a() as $v)
    echo $v.',';
echo '#end main#';
?>

output

#start main# {start[1,2,3,4,5,6,7,8,9,]end} #end main#

advanced example

<?php
echo '#start main# ';
function a(){
    echo '{start[';
    for($i=1; $i<=9; $i++)
        yield $i;
    echo ']end} ';
}
foreach(a() as $k => $v){
    if($k === 5)
        break;
    echo $k.'=>'.$v.',';
}
echo '#end main#';
?>

output

#start main# {start[0=>1,1=>2,2=>3,3=>4,4=>5,#end main#

This can be done in a single line, as long as the worksheet is active:

ActiveSheet.Visible = xlSheetHidden

However, you may not want to do this, especially if you use any "select" operations or you use any more ActiveSheet operations.

For me, the error was a result of a third-party library that I imported that used older Google Support Library modules. I simply updated them to the latest version (checking on Github for example), and the error was gone. I suggest checking all the non-Google libraries that you included in your build.gradle are up to date.

This is what I did and worked for me.

I want to undo the changes in multiple commits that I did for certain times and want to go to the previous commit point.

1. Go to Team -> Show History.
2. Right-click on the or range of revisions you want to ignore.
3. Select the "Revert changes" option.

This will run a reverse merge, undoing the changes in your working copy.

Just review the code and commit.

$('tbody :visible').highlight(myArray[i]); // works for all children of tbody that are visible

or

$('tbody:visible').highlight(myArray[i]); // works for all visible tbodys

Additionally, since you seem to be applying a class to the highlighted words, instead of using jquery to alter the background for all matched highlights, just create a css rule with the background color you need and it gets applied directly once you assign the class.

.highlight { background-color: #FFFF88; }

Take a look at the JavaDoc for RestTemplate.

There is the corresponding getForObject methods that are the HTTP GET equivalents of postForObject, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.

Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange methods allow you to provide an HttpEntity object representing the details of the request (including headers). The execute methods allow you to specify a RequestCallback from which you can add the headers upon its invocation.

you use the scrollTop attribute

var position = document.getElementById('id').scrollTop;

another solution is to override the join operator of the str class.

Let us define a new class my_string as follows

class my_string(str):
    def join(self, l):
        l_tmp = [str(x) for x in l]
        return super(my_string, self).join(l_tmp)

Then you can do

class Obj:
    def __str__(self):
        return 'name'

list = [Obj(), Obj(), Obj()]
comma = my_string(',')

print comma.join(list)

and you get

name,name,name

BTW, by using list as variable name you are redefining the list class (keyword) ! Preferably use another identifier name.

Hope you'll find my answer useful.

The simplest method is

$dateArray = explode('/', $_POST['date']);
$date = $dateArray[2].'-'.$dateArray[0].'-'.$dateArray[1];

$sql = mysql_query("INSERT INTO user_date (column,column,column) VALUES('',$name,$date)") or die (mysql_error());

I include #include <conio.h> and then, add getch(); just before the return 0; line. That's what I learnt at school anyway. The methods mentioned above here are quite different I see.

Its a simple xml design. It looks like iOS switch, check this below image

You need to create custom_thumb.xml and custom_track.xml

This is my switch,I need a very big switch so added layout_width/layout_height parameter

 <androidx.appcompat.widget.SwitchCompat
        android:id="@+id/swOnOff"
        android:layout_width="@dimen/_200sdp"
        android:layout_marginStart="@dimen/_50sdp"
        android:layout_marginEnd="@dimen/_50sdp"
        android:layout_marginTop="@dimen/_30sdp"
        android:layout_gravity="center"
        app:showText="true"
        android:textSize="@dimen/_20ssp"
        android:fontFamily="@font/opensans_bold"
        app:track="@drawable/custom_track"
        android:thumb="@drawable/custom_thumb"
        android:layout_height="@dimen/_120sdp"/>

Now create custom_thumb.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">
        <shape android:shape="oval">
            <solid android:color="#ffffff"/>
            <size android:width="@dimen/_100sdp"
                android:height="@dimen/_100sdp"/>
            <stroke android:width="1dp"
                android:color="#8c8c8c"/>
        </shape>
    </item>
    <item android:state_checked="true">
        <shape android:shape="oval">
            <solid android:color="#ffffff"/>
            <size android:width="@dimen/_100sdp"
                android:height="@dimen/_100sdp"/>
            <stroke android:width="1dp"
                android:color="#34c759"/>
        </shape>
    </item>
</selector>

Now create custom_track.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">
        <shape android:shape="rectangle">
            <corners android:radius="@dimen/_100sdp" />
            <solid android:color="#ffffff" />
            <stroke android:color="#8c8c8c" android:width="1dp"/>
            <size android:height="20dp" />
        </shape>
    </item>
    <item android:state_checked="true">
        <shape android:shape="rectangle">
            <corners android:radius="@dimen/_100sdp" />
            <solid android:color="#34c759" />
            <stroke android:color="#8c8c8c" android:width="1dp"/>
            <size android:height="20dp" />
        </shape>
    </item>
</selector>

According to the official site. These are the two ways

<div>
  {/* Comment goes here */}
  Hello, {name}!
</div>

Second Example:

<div>
    {/* It also works 
    for multi-line comments. */}
    Hello, {name}! 
</div>

Here is the link: https://reactjs.org/docs/faq-build.html#how-can-i-write-comments-in-jsx

For Python version 3:

pip install pysqlite3 

1. Like the rest of the users say it is easiest to do this with CURL.

2. If curl isn't available for you then maybe http://netevil.org/blog/2006/nov/http-post-from-php-without-curl

3. If that isn't possible you could write sockets yourself http://petewarden.typepad.com/searchbrowser/2008/06/how-to-post-an.html

onResume() is one of the methods called throughout the activity lifecycle. onResume() is the counterpart to onPause() which is called anytime an activity is hidden from view, e.g. if you start a new activity that hides it. onResume() is called when the activity that was hidden comes back to view on the screen.

You're question asks abou what method is used to restart an activity. onCreate() is called when the activity is first created. In practice, most activities persist in the background through a series of onPause() and onResume() calls. An activity is only really "restarted" by onRestart() if it is first fully stopped by calling onStop() and then brought back to life. Thus if you are not actually stopping activities with onStop() it is most likley you will be using onResume().

Read the android doc in the above link to get a better understanding of the relationship between the different lifestyle methods. Regardless of which lifecycle method you end up using the general format is the same. You must override the standard method and include your code, i.e. what you want the activity to do at that point, in the commented section.

@Override
public void onResume(){
 //will be executed onResume
}

It's stored in the process (shell) and since you've exported it, any processes that process spawns.

Doing the above doesn't store it anywhere in the filesystem like /etc/profile. You have to put it there explicitly for that to happen.

I know this is well answered, but if you're interested, I wrote a library that makes executing commands much easier.

Check it out here: https://github.com/twitchax/Sheller.

CONDA UPDATE - NO WRITE ACCESS PROBLEM ## FIXED##

SIMPLE SOLUTION:

1. Press the Windows+S combination button and type "cmd" into it.
2. Right click on the Command Prompt App result that shows up and click on "Run as administrator"
3. Now, in the black window that is open (i.e. your Command prompt), copy and paste the following to check for your version: conda --version
4. If you want the latest update, then update Conda by running the update command by pasting the following and clicking enter in the command prompt(black window): conda update conda
5. If a newer version is available, it will prompt you for a yes/no to install the update. Type "yes" and then press Enter to update.

If using Sublime Text 3:

• Go to Preferences -> Settings
• Under Preferences.sublime-settings—User add "esversion": 6

Our array of objects

var someData = [
   {firstName: "Max", lastName: "Mustermann", age: 40},
   {firstName: "Hagbard", lastName: "Celine", age: 44},
   {firstName: "Karl", lastName: "Koch", age: 42},
];

with for...in

var employees = {
    accounting: []
};

for(var i in someData) {    

    var item = someData[i];   

    employees.accounting.push({ 
        "firstName" : item.firstName,
        "lastName"  : item.lastName,
        "age"       : item.age 
    });
}

or with Array.prototype.map(), which is much cleaner:

var employees = {
    accounting: []
};

someData.map(function(item) {        
   employees.accounting.push({ 
        "firstName" : item.firstName,
        "lastName"  : item.lastName,
        "age"       : item.age 
    });
}

The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example:

median(x = 1:10)
x   
## Error: object 'x' not found

In this case, x is declared within the scope of the function, so it does not exist in the user workspace.

median(x <- 1:10)
x    
## [1]  1  2  3  4  5  6  7  8  9 10

In this case, x is declared in the user workspace, so you can use it after the function call has been completed.

There is a general preference among the R community for using <- for assignment (other than in function signatures) for compatibility with (very) old versions of S-Plus. Note that the spaces help to clarify situations like

x<-3
# Does this mean assignment?
x <- 3
# Or less than?
x < -3

Most R IDEs have keyboard shortcuts to make <- easier to type. Ctrl + = in Architect, Alt + - in RStudio (Option + - under macOS), Shift + - (underscore) in emacs+ESS.

If you prefer writing = to <- but want to use the more common assignment symbol for publicly released code (on CRAN, for example), then you can use one of the tidy_* functions in the formatR package to automatically replace = with <-.

library(formatR)
tidy_source(text = "x=1:5", arrow = TRUE)
## x <- 1:5

The answer to the question "Why does x <- y = 5 throw an error but not x <- y <- 5?" is "It's down to the magic contained in the parser". R's syntax contains many ambiguous cases that have to be resolved one way or another. The parser chooses to resolve the bits of the expression in different orders depending on whether = or <- was used.

To understand what is happening, you need to know that assignment silently returns the value that was assigned. You can see that more clearly by explicitly printing, for example print(x <- 2 + 3).

Secondly, it's clearer if we use prefix notation for assignment. So

x <- 5
`<-`(x, 5)  #same thing

y = 5
`=`(y, 5)   #also the same thing

The parser interprets x <- y <- 5 as

`<-`(x, `<-`(y, 5))

We might expect that x <- y = 5 would then be

`<-`(x, `=`(y, 5))

but actually it gets interpreted as

`=`(`<-`(x, y), 5)

This is because = is lower precedence than <-, as shown on the ?Syntax help page.

I suggest this and all the cells for the particular table are effected.

table.tbl_classname td, th {
    padding: 5px 5px 5px 4px;
 }

Just for completion, this is the code from google guava library. It is not my code, but I think it is valueable to show it here in this thread.

  /** Maximum loop count when creating temp directories. */
  private static final int TEMP_DIR_ATTEMPTS = 10000;

  /**
   * Atomically creates a new directory somewhere beneath the system's temporary directory (as
   * defined by the {@code java.io.tmpdir} system property), and returns its name.
   *
   * <p>Use this method instead of {@link File#createTempFile(String, String)} when you wish to

   */
  public static File createTempDir() {
    File baseDir = new File(System.getProperty("java.io.tmpdir"));
    String baseName = System.currentTimeMillis() + "-";

    for (int counter = 0; counter < TEMP_DIR_ATTEMPTS; counter++) {
      File tempDir = new File(baseDir, baseName + counter);
      if (tempDir.mkdir()) {
        return tempDir;
      }
    }
    throw new IllegalStateException(
        "Failed to create directory within "
            + TEMP_DIR_ATTEMPTS
            + " attempts (tried "
            + baseName
            + "0 to "
            + baseName
            + (TEMP_DIR_ATTEMPTS - 1)
            + ')');
  }

Try this MEX file for ACTUALLY calling Python from MATLAB not the other way around as others suggest. It provides fairly decent integration : http://algoholic.eu/matpy/

You can do something like this easily:

[X,Y]=meshgrid(-10:0.1:10,-10:0.1:10);
Z=sin(X)+cos(Y);
py_export('X','Y','Z')
stmt = sprintf(['import matplotlib\n' ...
'matplotlib.use(''Qt4Agg'')\n' ...
'import matplotlib.pyplot as plt\n' ...
'from mpl_toolkits.mplot3d import axes3d\n' ...
'f=plt.figure()\n' ...
'ax=f.gca(projection=''3d'')\n' ...
'cset=ax.plot_surface(X,Y,Z)\n' ...
'ax.clabel(cset,fontsize=9,inline=1)\n' ...
'plt.show()']);
py('eval', stmt);

try {
} catch (javax.script.ScriptException ex) {
// System.out.println(ex.getMessage());
}

This should do it:

sed -e s/deletethis//g -i *
sed -e "s/deletethis//g" -i.backup *
sed -e "s/deletethis//g" -i .backup *

it will replace all occurrences of "deletethis" with "" (nothing) in all files (*), editing them in place.

In the second form the pattern can be edited a little safer, and it makes backups of any modified files, by suffixing them with ".backup".

The third form is the way some versions of sed like it. (e.g. Mac OS X)

man sed for more information.

Try to set response dataType property directly:

dataType: 'text'

and put

die(''); 

in the end of your php file. You've got error callback cause jquery cannot parse your response. In anyway, you may use a "complete:" callback, just to make sure your request has been processed.

Go to Preferences > User Settings. (Alternatively, Ctrl + , / Cmd + , on macOS)

Then you can type inside the JSON object any settings you want to override. User settings are per user. You can also configure workspace settings, which are for the project that you are currently working on.

Here's an example:

// Controls the font family.
"editor.fontFamily": "Consolas",

// Controls the font size.
"editor.fontSize": 13

It's a syntactically valid request, but not a satisfiable request. If you look further in that section you see:

If a syntactically valid byte-range-set includes at least one byte- range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffix-byte-range-spec with a non- zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable). Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body.

So I think in your example, the server should return a 416 since it's not a valid byte range for that file.

When you create a new ASP.NET Core 2.0 application, this hook is included by default. In previous versions of EF Core and ASP.NET Core, the tools try to invoke Startup.ConfigureServices directly in order to obtain the application's service provider, but this pattern no longer works correctly in ASP.NET Core 2.0 applications. If you are upgrading an ASP.NET Core 1.x application to 2.0, you can modify your Program class to follow the new pattern.

Add Factory in .Net Core 2.x

public class BloggingContextFactory : IDesignTimeDbContextFactory<BloggingContext>
    {
        public BloggingContext CreateDbContext(string[] args)
        {
            var optionsBuilder = new DbContextOptionsBuilder<BloggingContext>();
            optionsBuilder.UseSqlite("Data Source=blog.db");

            return new BloggingContext(optionsBuilder.Options);
        }
    }

this should work:

for numbers, strings, date, etc.:

    public static void MyMethod(object obj)
    {
        if (typeof(IDictionary).IsAssignableFrom(obj.GetType()))
        {
            IDictionary idict = (IDictionary)obj;

            Dictionary<string, string> newDict = new Dictionary<string, string>();
            foreach (object key in idict.Keys)
            {
                newDict.Add(key.ToString(), idict[key].ToString());
            }
        }
        else
        {
            // My object is not a dictionary
        }
    }

if your dictionary also contains some other objects:

    public static void MyMethod(object obj)
    {
        if (typeof(IDictionary).IsAssignableFrom(obj.GetType()))
        {
            IDictionary idict = (IDictionary)obj;
            Dictionary<string, string> newDict = new Dictionary<string, string>();

            foreach (object key in idict.Keys)
            {
                newDict.Add(objToString(key), objToString(idict[key]));
            }
        }
        else
        {
            // My object is not a dictionary
        }
    }

    private static string objToString(object obj)
    {
        string str = "";
        if (obj.GetType().FullName == "System.String")
        {
            str = (string)obj;
        }
        else if (obj.GetType().FullName == "test.Testclass")
        {
            TestClass c = (TestClass)obj;
            str = c.Info;
        }
        return str;
    }

Here are a few ways to create a list with N of continuous natural numbers starting from 1.

1 range:

def numbers(n):

    return [i for i in range(1, n+1)]

You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!

.each() should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map.

var newArray = $(array).map(function(i) {
    return $('#event' + i, response).html();
});

Edit: I removed the adding of the prepended 0 since it is suggested to not use that.

If you must have it use

var newArray = $(array).map(function(i) {
    var number = '' + i;
    if (number.length == 1) {
        number = '0' + number;
    }   
    return $('#event' + number, response).html();
});

Add this two line in your style.xml

The diffrence is very simple:

Long version

If you want to have better readability, use Math.floor. But if you want to minimize it, use tilde ~~.

There are a lot of sources on the internet saying Math.floor is faster, but sometimes ~~. I would not recommend you think about speed because it is not going to be noticed when running the code. Maybe in tests etc, but no human can see a diffrence here. What would be faster is to use ~~ for a faster load time.

Short version

~~ is shorter/takes less space. Math.floor improves the readability. Sometimes tilde is faster, sometimes Math.floor is faster, but it is not noticeable.

How about using <input type="number"...>?

http://www.w3schools.com/tags/tag_input.asp

Also, here is a question that has some examples of using Javascript for validation.

Update: linked to better question (thanks alexblum).

post.capabilities.items will still be defined because it's an empty array, if you check post.capabilities.items.length it should work fine because 0 is falsy.

This is about as efficient as it can get, buffered binary read, no string conversion,

FileInputStream stream = new FileInputStream("/tmp/test.txt");
byte[] buffer = new byte[8192];
int count = 0;
int n;
while ((n = stream.read(buffer)) > 0) {
    for (int i = 0; i < n; i++) {
        if (buffer[i] == '\n') count++;
    }
}
stream.close();
System.out.println("Number of lines: " + count);

1. A keystore contains private keys. You only need this if you are a server, or if the server requires client authentication.

2. A truststore contains CA certificates to trust. If your server’s certificate is signed by a recognized CA, the default truststore that ships with the JRE will already trust it (because it already trusts trustworthy CAs), so you don’t need to build your own, or to add anything to the one from the JRE.

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

The approach I've found workable is git's submodule system. Using that you can submodule in a given version of the code and upgrading/downgrading is explicit and recorded - never haphazard.

The folder structure I've taken with this is:

+ myproject
++ src
+++ myproject
+++ github.com
++++ submoduled_project of some kind.

is simple for me use base64_encode

$term = base64_encode($term) 
$url = $youurl.'?term='.$term

after you decode the term

$term = base64_decode($['GET']['term'])

this way encode the "/" and "\"

You also might want to check if the file already exists to avoid replacing the file by accident (unless that is the idea of course:

Dim filepath as String = "C:\my files\2010\SomeFileName.txt"
If Not System.IO.File.Exists(filepath) Then
   System.IO.File.Create(filepath).Dispose()
End If

It looks like data not contains what you think it contains - check it.

let data={"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"};_x000D_
_x000D_
console.log( data["jobtitel"] );_x000D_
console.log( data.jobtitel );

I think it's a matter of personal preference. I prefer to do it in the following way:

   var /* Variables */
            me = this, that = scope,
            temp, tempUri, tempUrl,
            videoId = getQueryString()["id"],
            host = location.protocol + '//' + location.host,
            baseUrl = "localhost",
            str = "Visit W3Schools",
            n = str.search(/w3schools/i),
            x = 5,
            y = 6,
            z = x + y
   /* End Variables */;

Best solution would be this which is provided by npm documentation.

For Ubuntu suggested solution is Option#2

Brief steps:
Make a directory for global installations:
mkdir ~/.npm-global

Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
npm config get prefix can help you to verify if prefix was updated or not. The result would be <Your Home Directory>/.npm-global

Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH

Back on the command line, update your system variables:
source ~/.profile

Instead of steps 2-4 you can also use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global

For Mac suggested solution is Option#3

On Mac OS you can avoid this problem altogether by using the Homebrew package manager

brew install node

Antti Sykäri's algorithm is nice and short. I initially made a variation that replaced JavaScript's Math.random when you call Math.seed(s), but then Jason commented that returning the function would be better:

Math.seed = function(s) {
    return function() {
        s = Math.sin(s) * 10000; return s - Math.floor(s);
    };
};

// usage:
var random1 = Math.seed(42);
var random2 = Math.seed(random1());
Math.random = Math.seed(random2());

This gives you another functionality that JavaScript doesn't have: multiple independent random generators. That is especially important if you want to have multiple repeatable simulations running at the same time.

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

you can error handling according to content-type

Additionally, handling according to status code.

app.js

import express from 'express';

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// when status is 404, error handler
app.use(function(err, req, res, next) {
    // set locals, only providing error in development
    res.locals.message = err.message;
    res.locals.error = req.app.get('env') === 'development' ? err : {};

    // render the error page
    res.status(err.status || 500);
    if( 404 === err.status  ){
        res.format({
            'text/plain': () => {
                res.send({message: 'not found Data'});
            },
            'text/html': () => {
                res.render('404.jade');
            },
            'application/json': () => {
                res.send({message: 'not found Data'});
            },
            'default': () => {
                res.status(406).send('Not Acceptable');
            }
        })
    }

    // when status is 500, error handler
    if(500 === err.status) {
        return res.send({message: 'error occur'});
    }
});

404.jade

doctype html

html
  head
    title 404 Not Found

    meta(http-equiv="Content-Type" content="text/html; charset=utf-8")
    meta(name = "viewport" content="width=device-width, initial-scale=1.0 user-scalable=no")

  body
      h2 Not Found Page
      h2 404 Error Code

If you can using res.format, You can write simple error handling code.

Recommendation res.format() instead of res.accepts().

If the 500 error occurs in the previous code, if(500 == err.status){. . . } is called

The shape attribute for numpy arrays returns the dimensions of the array. If Y has n rows and m columns, then Y.shape is (n,m). So Y.shape[0] is n.

In [46]: Y = np.arange(12).reshape(3,4)

In [47]: Y
Out[47]: 
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

In [48]: Y.shape
Out[48]: (3, 4)

In [49]: Y.shape[0]
Out[49]: 3

Replace next() with nextLine():

String productDescription = input.nextLine();

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

Swift version

This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.

DispatchQueue.global(qos: .background).async {
    
    // Background Thread
    
    DispatchQueue.main.async {
        // Run UI Updates
    }
}

If you want to select only one of two nodes with union operator, you can use this solution: (//bookstore/book/title | //bookstore/city/zipcode/title)[1]

8 years late. But I like:

import os
import requests

os.environ['HTTP_PROXY'] = os.environ['http_proxy'] = 'http://http-connect-proxy:3128/'
os.environ['HTTPS_PROXY'] = os.environ['https_proxy'] = 'http://http-connect-proxy:3128/'
os.environ['NO_PROXY'] = os.environ['no_proxy'] = '127.0.0.1,localhost,.local'

r = requests.get('https://example.com')  # , verify=False

You can define the default value from the 'data' attribute. This is part of the Abstract "field" type (http://symfony.com/doc/2.0/reference/forms/types/field.html)

$form = $this->createFormBuilder()
            ->add('status', 'choice', array(
                'choices' => array(
                    0 => 'Published',
                    1 => 'Draft'
                ),
                'data' => 1
            ))
            ->getForm();

In this example, 'Draft' would be set as the default selected value.

Launchd is a the preferred way in OS X.

If you want it to run on your login put it in ~/Library/LaunchAgents

Start launchd item

launchctl load /Library/LaunchDaemons/com.bob.plist

Stop item

launchctl unload /Library/LaunchDaemons/com.bob.plist

Example com.bob.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<key>Label</key>
<string>com.bob</string>
<key>RunAtLoad</key>

<key>ProgramArguments</key>
<array>
<string>/usr/bin/java</string>

Add this in your css file:

.custom_class
 {
    background-image: url(../img/beach.jpg);
    -moz-background-size: cover;
    -webkit-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
 }

and then, in your .html (or .php) file call this class like that:

<div class="custom_class">
   ...
</div>

With ES6 now widely supported, the best answer to this question has changed. ES6 provides the let and const keywords for this exact circumstance. Instead of messing around with closures, we can just use let to set a loop scope variable like this:

var funcs = [];_x000D_
_x000D_
for (let i = 0; i < 3; i++) {          _x000D_
    funcs[i] = function() {            _x000D_
      console.log("My value: " + i); _x000D_
    };_x000D_
}

val will then point to an object that is specific to that particular turn of the loop, and will return the correct value without the additional closure notation. This obviously significantly simplifies this problem.

const is similar to let with the additional restriction that the variable name can't be rebound to a new reference after initial assignment.

Browser support is now here for those targeting the latest versions of browsers. const/let are currently supported in the latest Firefox, Safari, Edge and Chrome. It also is supported in Node, and you can use it anywhere by taking advantage of build tools like Babel. You can see a working example here: http://jsfiddle.net/ben336/rbU4t/2/

Docs here:

• const
• let

Beware, though, that IE9-IE11 and Edge prior to Edge 14 support let but get the above wrong (they don't create a new i each time, so all the functions above would log 3 like they would if we used var). Edge 14 finally gets it right.

Best way to do this is

int i = 3;
Double d = i * 1.0;

d is 3.0 now.

At a command line:

SQLCMD -L

or

OSQL -L

(Note: must be a capital L)

This will list all the sql servers installed on your network. There are configuration options you can set to prevent a SQL Server from showing in the list. To do this...

At command line:

svrnetcn

In the enabled protocols list, select 'TCP/IP', then click properties. There is a check box for 'Hide server'.

$a = "This", "Is", "a", "cat"

foreach ( $word in $a ) { $sent = "$sent $word" }
$sent = $sent.Substring(1)

Write-Host $sent

I had something similar happen to me just recently. I updated my iPhone to 8.1.3, and started getting the 'application could not be verified' error message from Xcode on an app that installed just fine on the same iOS device from the same Mac just a few days ago.

I deleted the app from the device, restarted Xcode, and the app subsequently installed on the device just fine without any error message. Not sure if deleting the app was the fix, or the problem was due to "the phase of the moon".

char *a = "stack overflow";
char *b = "new string, it's real";
int d = strlen(a);

b = malloc(d * sizeof(char));
b = strcpy(b,a);
printf("%s %s\n", a, b);

Ensure that you have following JARS in place: 1) jackson-core-asl-1.9.13 2) jackson-jaxrs-1.9.13 3) jackson-mapper-asl-1.9.13 4) jackson-xc-1.9.13

It would be helpful to understand why you need to do this with lodash. If you just want to check if a key exists in an object, you don't need lodash.

myObject.options.hasOwnProperty('property');

If your looking to see if a value exists, you can use _.invert

_.invert(myObject.options)[value]

I had the problem a few weeks ago with a few discrete features which were formatted as 'object'. This solution seemed to work.

for col in discrete:
df[col] = pd.to_numeric(df[col], errors='coerce').astype(pd.Int64Dtype())

Use this, I think I can get your idea.

Live demo: http://jsfiddle.net/oscarj24/h722g/1/

$('body').click(function(e) {

    var target = $(e.target), article;

    if (target.is('#news_gallery li .over')) {
       article = $('#news-article .news-article');
    } else if (target.is('#work_gallery li .over')) {
       article = $('#work-article .work-article');
    } else if (target.is('#search-item li')) {
       article = $('#search-item .search-article');
    }

    if (article) {
       // Do Something
    }
});?

NSDate is a specific point in time without a time zone. Think of it as the number of seconds that have passed since a reference date. How many seconds have passed in one time zone vs. another since a particular reference date? The answer is the same.

Depending on how you output that date (including looking at the debugger), you may get an answer in a different time zone.

If they ran at the same moment, the values of these are the same. They're both the number of seconds since the reference date, which may be formatted on output to UTC or local time. Within the date variable, they're both UTC.

Objective-C:

NSDate *UTCDate = [NSDate date]

Swift:

let UTCDate = NSDate.date()

To explain this, we can use a NSDateFormatter in a playground:

import UIKit

let date = NSDate.date()
    // "Jul 23, 2014, 11:01 AM" <-- looks local without seconds. But:

var formatter = NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZ"
let defaultTimeZoneStr = formatter.stringFromDate(date)
    // "2014-07-23 11:01:35 -0700" <-- same date, local, but with seconds
formatter.timeZone = NSTimeZone(abbreviation: "UTC")
let utcTimeZoneStr = formatter.stringFromDate(date)
    // "2014-07-23 18:01:41 +0000" <-- same date, now in UTC

The date output varies, but the date is constant. This is exactly what you're saying. There's no such thing as a local NSDate.

As for how to get microseconds out, you can use this (put it at the bottom of the same playground):

let seconds = date.timeIntervalSince1970
let microseconds = Int(seconds * 1000) % 1000 // chops off seconds

To compare two dates, you can use date.compare(otherDate).

See the documentation on plt.axis(). This:

plt.axis('equal')

doesn't work because it changes the limits of the axis to make circles appear circular. What you want is:

plt.axis('square')

This creates a square plot with equal axes.
