Programs & Examples On #Ieaddon

Here's a bit more complicated example with piping and variable assignment inside recipe:

getpodname:
    # Getting pod name
    @eval $$(minikube docker-env) ;\
    $(eval PODNAME=$(shell sh -c "kubectl get pods | grep profile-posts-api | grep Running" | awk '{print $$1}'))
    echo $(PODNAME)

if one row has value in field1 column and other rows have null value then this Query might work.

SELECT
  FK,
  MAX(Field1) as Field1,
  MAX(Field2) as Field2
FROM 
(
select FK,ISNULL(Field1,'') as Field1,ISNULL(Field2,'') as Field2 from table1
)
tbl
GROUP BY FK

Try these (reference):

clear linenum
clear filename:linenum

To keep beginner attitude you can explain that all the command line is automaticaly splite in a array fo String (the String[]).

For static you have to explain, that it not a field like another : it is unique in the JVM even if you have thousand instances of the class

So main is static, because it is the only way to find it (linked in its own class) in a jar.

... after you look at coding, and your job begin ...

This is my working code for express 4.0.

express 4.0 is very different from 3.0 and others.

4.0 you have /bin/www file, which you are going to add https here.

"npm start" is standard way you start express 4.0 server.

readFileSync() function should use __dirname get current directory

while require() use ./ refer to current directory.

First you put private.key and public.cert file under /bin folder, It is same folder as WWW file.

no such directory found error:

  key: fs.readFileSync('../private.key'),

  cert: fs.readFileSync('../public.cert')

error, no such directory found

  key: fs.readFileSync('./private.key'),

  cert: fs.readFileSync('./public.cert')

Working code should be

key: fs.readFileSync(__dirname + '/private.key', 'utf8'),

cert: fs.readFileSync(__dirname + '/public.cert', 'utf8')

Complete https code is:

const https = require('https');
const fs = require('fs');

// readFileSync function must use __dirname get current directory
// require use ./ refer to current directory.

const options = {
   key: fs.readFileSync(__dirname + '/private.key', 'utf8'),
  cert: fs.readFileSync(__dirname + '/public.cert', 'utf8')
};


 // Create HTTPs server.

 var server = https.createServer(options, app);

Here is a more flexible solution using a closure:

$my_array = array("foo" => 1, "hello" => "world");
$allowed = array("foo", "bar");
$result = array_flip(array_filter(array_flip($my_array), function ($key) use ($allowed)
{
    return in_array($key, $allowed);
}));
var_dump($result);

Outputs:

array(1) {
  'foo' =>
  int(1)
}

So in the function, you can do other specific tests.

One thing I did and it works wonders is to read both objects into HashMap and then compare with a regular assertEquals(). It will call the equals() method of the hashmaps, which will recursively compare all objects inside (they will be either other hashmaps or some single value object like a string or integer). This was done using Codehaus' Jackson JSON parser.

assertEquals(mapper.readValue(expectedJson, new TypeReference<HashMap<String, Object>>(){}), mapper.readValue(actualJson, new TypeReference<HashMap<String, Object>>(){}));

A similar approach can be used if the JSON object is an array instead.

if you omit the format attribute from the attr element, you can use it to reference a class from XML layouts.

• example from attrs.xml.
• Android Studio understands that the class is being referenced from XML
  • i.e.
    • Refactor > Rename works
    • Find Usages works
    • and so on...

don't specify a format attribute in .../src/main/res/values/attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <declare-styleable name="MyCustomView">
        ....
        <attr name="give_me_a_class"/>
        ....
    </declare-styleable>

</resources>

use it in some layout file .../src/main/res/layout/activity__main_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<SomeLayout
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <!-- make sure to use $ dollar signs for nested classes -->
    <MyCustomView
        app:give_me_a_class="class.type.name.Outer$Nested/>

    <MyCustomView
        app:give_me_a_class="class.type.name.AnotherClass/>

</SomeLayout>

parse the class in your view initialization code .../src/main/java/.../MyCustomView.kt

class MyCustomView(
        context:Context,
        attrs:AttributeSet)
    :View(context,attrs)
{
    // parse XML attributes
    ....
    private val giveMeAClass:SomeCustomInterface
    init
    {
        context.theme.obtainStyledAttributes(attrs,R.styleable.ColorPreference,0,0).apply()
        {
            try
            {
                // very important to use the class loader from the passed-in context
                giveMeAClass = context::class.java.classLoader!!
                        .loadClass(getString(R.styleable.MyCustomView_give_me_a_class))
                        .newInstance() // instantiate using 0-args constructor
                        .let {it as SomeCustomInterface}
            }
            finally
            {
                recycle()
            }
        }
    }

The SpecialCells Does not actually work as it needs to be continuous. I have solved this by adding a sort funtion in order to sort the data based on the coloumns i need.

Sorry for no comments on the code as i was not planning to share it:

Sub testtt()
    arr = FilterAndGetData(Worksheets("Data").range("A:K"), Array(1, 9), Array("george", "WeeklyCash"), Array(1, 2, 3, 10, 11), 1)
    Debug.Print sms(arr)
End Sub
Function FilterAndGetData(ByVal rng As Variant, ByVal fields As Variant, ByVal criterias As Variant, ByVal colstoreturn As Variant, ByVal headers As Boolean) As Variant
Dim SUset, EAset, CMset
If Application.ScreenUpdating Then Application.ScreenUpdating = False: SUset = False Else SUset = True
If Application.EnableEvents Then Application.EnableEvents = False: EAset = False Else EAset = True
If Application.Calculation = xlCalculationAutomatic Then Application.Calculation = xlCalculationManual: CMset = False Else CMset = True
For Each col In rng.Columns: col.Hidden = False: Next col

Dim oldsheet, scol, ecol, srow, hyesno As String
Dim i, counter As Integer

oldsheet = ActiveSheet.Name


Worksheets(rng.Worksheet.Name).Activate

Worksheets(rng.Worksheet.Name).AutoFilterMode = False

scol = Chr(rng.Column + 64)
ecol = Chr(rng.Columns.Count + rng.Column + 64 - 1)
srow = rng.row

If UBound(fields) - LBound(fields) <> UBound(criterias) - LBound(criterias) Then FilterAndGetData = "Fields&Crit. counts dont match": GoTo done

dd = sortrange(rng, colstoreturn, headers)

For i = LBound(fields) To UBound(fields)
    rng.AutoFilter Field:=CStr(fields(i)), Criteria1:=CStr(criterias(i))
Next i

Dim rngg As Variant

rngg = rng.SpecialCells(xlCellTypeVisible)
Debug.Print ActiveSheet.AutoFilter.range.address
FilterAndGetData = ActiveSheet.AutoFilter.range.SpecialCells(xlCellTypeVisible).Value

For Each row In rng.Rows
    If row.EntireRow.Hidden Then Debug.Print yes
Next row


done:
    'Worksheets("Data").AutoFilterMode = False
    Worksheets(oldsheet).Activate
    If SUset Then Application.ScreenUpdating = True
    If EAset Then Application.EnableEvents = True
    If CMset Then Application.Calculation = xlCalculationAutomatic
End Function
Function sortrange(ByVal rng As Variant, ByVal colnumbers As Variant, ByVal headers As Boolean)

    Dim SUset, EAset, CMset
    If Application.ScreenUpdating Then Application.ScreenUpdating = False: SUset = False Else SUset = True
    If Application.EnableEvents Then Application.EnableEvents = False: EAset = False Else EAset = True
    If Application.Calculation = xlCalculationAutomatic Then Application.Calculation = xlCalculationManual: CMset = False Else CMset = True
    For Each col In rng.Columns: col.Hidden = False: Next col

    Dim oldsheet, scol, srow, sortcol, hyesno As String
    Dim i, counter As Integer
    oldsheet = ActiveSheet.Name
    Worksheets(rng.Worksheet.Name).Activate
    Worksheets(rng.Worksheet.Name).AutoFilterMode = False
    scol = rng.Column
    srow = rng.row

    If headers Then hyesno = xlYes Else hyesno = xlNo

    For i = LBound(colnumbers) To UBound(colnumbers)
        rng.Sort key1:=range(Chr(scol + colnumbers(i) + 63) + CStr(srow)), order1:=xlAscending, Header:=hyesno
    Next i
    sortrange = "123"
done:
    Worksheets(oldsheet).Activate
    If SUset Then Application.ScreenUpdating = True
    If EAset Then Application.EnableEvents = True
    If CMset Then Application.Calculation = xlCalculationAutomatic
End Function

Another reason why an undefined index notice will be thrown, would be that a column was omitted from a database query.

I.e.:

$query = "SELECT col1 FROM table WHERE col_x = ?";

Then trying to access more columns/rows inside a loop.

I.e.:

print_r($row['col1']);
print_r($row['col2']); // undefined index thrown

or in a while loop:

while( $row = fetching_function($query) ) {

    echo $row['col1'];
    echo "<br>";
    echo $row['col2']; // undefined index thrown
    echo "<br>";
    echo $row['col3']; // undefined index thrown

}

Something else that needs to be noted is that on a *NIX OS and Mac OS X, things are case-sensitive.

Consult the followning Q&A's on Stack:

• Are table names in MySQL case sensitive?

• mysql case sensitive table names in queries

• MySql - Case Sensitive issue of tables in different server

Easiest solution is to use BuildConfig.

I use BuildConfig.VERSION_NAME in my application.

You can also use BuildConfig.VERSION_CODE to get version code.

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=
    (MyclassFragment)getSupportFragmentManager().findFragmentById(R.id.idFragment);

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

Check out the GLPaint example.

http://developer.apple.com/library/ios/#samplecode/GLPaint/Introduction/Intro.html

Follow the example --

songs = [
{"title": "happy birthday", "playcount": 4},
{"title": "AC/DC", "playcount": 2},
{"title": "Billie Jean", "playcount": 6},
{"title": "Human Touch", "playcount": 3}
]

print("===========================")
print(f'Songs --> {songs} \n')
title = list(map(lambda x : x['title'], songs))
print(f'Print Title --> {title}')

playcount = list(map(lambda x : x['playcount'], songs))
print(f'Print Playcount --> {playcount}')
print (f'Print Sorted playcount --> {sorted(playcount)}')

# Aliter -
print(sorted(list(map(lambda x: x['playcount'],songs))))

For those who want an elegant, bash version-independent solution (in fact should work in other modern shells) and those who love to use one-liners for quick tasks. Here we go!

ls | grep . && echo 'files found' || echo 'files not found'

(note as one of the comments mentioned, ls -al and in fact, just -l and -a will all return something, so in my answer I use simple ls

MY PREFERRED METHOD is using fopen,fwrite and fclose [it will cost less CPU]

$f=fopen('myfile.txt','w');
fwrite($f,'new content');
fclose($f);

Warning for those using file_put_contents

It'll affect a lot in performance, for example [on the same class/situation] file_get_contents too: if you have a BIG FILE, it'll read the whole content in one shot and that operation could take a long waiting time

open the command prompt Go to project directory

type git remote add origin your git hub repository location with.git

Use .is(':checked') to determine whether or not it's checked, and then set your value accordingly.

More information here.

Slightly off-topic to your question, but it's probably worth mentioning anyway:

Commons Lang has got some excellent methods you can use in overriding equals and hashcode. Check out EqualsBuilder.reflectionEquals(...) and HashCodeBuilder.reflectionHashCode(...). Saved me plenty of headache in the past - although of course if you just want to do "equals" on ID it may not fit your circumstances.

I also agree that you should use the @Override annotation whenever you're overriding equals (or any other method).

Use the ng-click directive:

<button my-directive ng-click="alertFn()">Click Me!</button>

// In <script>:
app.directive('myDirective' function() {
  return function(scope, element, attrs) {
    scope.alertFn = function() { alert('click'); };
  };
};

Note that you don't need my-directive in this example, you just need something to bind alertFn on the current scope.

Update: You also want the angular libraries loaded before your <script> block.

A more flexible jQuery plugin enabling you to keep a element after the ellipsis (for example a "read-more" button) and update onWindowResize. It also works around text with markup:

http://dotdotdot.frebsite.nl

>>> n = 5                     #length of list
>>> list = [None] * n         #populate list, length n with n entries "None"
>>> print(list)
[None, None, None, None, None]

>>> list.append(1)            #append 1 to right side of list
>>> list = list[-n:]          #redefine list as the last n elements of list
>>> print(list)
[None, None, None, None, 1]

>>> list.append(1)            #append 1 to right side of list
>>> list = list[-n:]          #redefine list as the last n elements of list
>>> print(list)
[None, None, None, 1, 1]

>>> list.append(1)            #append 1 to right side of list
>>> list = list[-n:]          #redefine list as the last n elements of list
>>> print(list)
[None, None, 1, 1, 1]

or with really nothing in the list to begin with:

>>> n = 5                     #length of list
>>> list = []                 # create list
>>> print(list)
[]

>>> list.append(1)            #append 1 to right side of list
>>> list = list[-n:]          #redefine list as the last n elements of list
>>> print(list)
[1]

on the 4th iteration of append:

>>> list.append(1)            #append 1 to right side of list
>>> list = list[-n:]          #redefine list as the last n elements of list
>>> print(list)
[1,1,1,1]

5 and all subsequent:

>>> list.append(1)            #append 1 to right side of list
>>> list = list[-n:]          #redefine list as the last n elements of list
>>> print(list)
[1,1,1,1,1]

I suggest a convenient way to solve this problem. Just assign the attribute "android:configChanges" value as followed in the Mainfest.xml for your errored activity. like this:

<activity android:name=".main.MainActivity"
              android:label="mainActivity"
              android:configChanges="orientation|keyboardHidden|navigation">
</activity>

the first solution I gave out had really reduced the frequency of OOM error to a low level. But, it did not solve the problem totally. And then I will give out the 2nd solution:

As the OOM detailed, I have used too much runtime memory. So, I reduce the picture size in ~/res/drawable of my project. Such as an overqualified picture which has a resolution of 128X128, could be resized to 64x64 which would also be suitable for my application. And after I did so with a pile of pictures, the OOM error doesn't occur again.

git reset --soft is just for that: it is like git reset --hard, but doesn't touch the files.

Try this:

^[-+]?(([0-8]\\d|\\d)(\\.\\d+)?|90(\\.0+)?)$,\s*^[-+]?((1[0-7]\\d(\\.\\d+)?)|(180(\\.0+)?)|(\\d\\d(\\.\\d+)?)|(\\d(\\.\\d+)?))$

With display grid you can dynamically adjust height of each section.

#body{
  display:grid;
  grid-template-rows:1fr 1fr 1fr;
}

Add the above code and you will get desired results.

Sometimes when many levels of grids are involved css wont restrict your #content to 1fr. In such scenarios use:

#content{
  max-height:100%;
}

Is #result in the response HTML? Try the following. jQuery will still return an empty object if it doesn't find anything.

alert(result.length);

It is possible but not the way you have it.

You have to add a no-args constructor to the base class and that's it!

public abstract class A {
    private String name;
    public A(){
        this.name = getName();
    }
    public abstract String getName();


    public String toString(){
        return "simple class name: " + this.getClass().getSimpleName() + " name:\"" + this.name + "\"";
    }
}
class B extends A {
    public String getName(){
        return "my name is B";
    }
    public static void main( String [] args ) {
        System.out.println( new C() );
    }
}
class C extends A {
    public String getName() {
        return "Zee";
    }
}

When you don't add a constructor ( any ) to a class the compiler add the default no arg contructor for you.

When the defualt no arg calls to super(); and since you don't have it in the super class you get that error message.

That's about the question it self.

Now, expanding the answer:

Are you aware that creating a subclass ( behavior ) to specify different a different value ( data ) makes no sense??!!! I hope you do.

If the only thing that is changes is the "name" then a single class parametrized is enough!

So you don't need this:

MyClass a = new A("A");
MyClass b = new B("B");
MyClass c = new C("C");
MyClass d = new D("D");

or

MyClass a = new A(); // internally setting "A" "B", "C" etc.
MyClass b = new B();
MyClass c = new C();
MyClass d = new D();

When you can write this:

MyClass a = new MyClass("A");
MyClass b = new MyClass("B");
MyClass c = new MyClass("C");
MyClass d = new MyClass("D");

If I were to change the method signature of the BaseClass constructor, I would have to change all the subclasses.

Well that's why inheritance is the artifact that creates HIGH coupling, which is undesirable in OO systems. It should be avoided and perhaps replaced with composition.

Think if you really really need them as subclass. That's why you see very often interfaces used insted:

 public interface NameAware {
     public String getName();
 }



 class A implements NameAware ...
 class B implements NameAware ...
 class C ... etc. 

Here B and C could have inherited from A which would have created a very HIGH coupling among them, by using interfaces the coupling is reduced, if A decides it will no longer be "NameAware" the other classes won't broke.

Of course, if you want to reuse behavior this won't work.

It looks to me like the UIWebView has a UIScrollView. You can use documented APIs for this, but bouncing is set for both directions, not individually. This is in the API docs. UIScrollView has a bounce property, so something like this works (don't know if there's more than one scrollview):

NSArray *subviews = myWebView.subviews;
NSObject *obj = nil;
int i = 0;
for (; i < subviews.count ; i++)
{
    obj = [subviews objectAtIndex:i];

    if([[obj class] isSubclassOfClass:[UIScrollView class]] == YES)
    {
        ((UIScrollView*)obj).bounces = NO;
    }
}

try this....

  public  void buildPushNotification(Context ctx, String content, int icon, CharSequence text, boolean silent) {
    Intent intent = new Intent(ctx, Activity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(ctx, 1410, intent, PendingIntent.FLAG_ONE_SHOT);

    Bitmap bm = BitmapFactory.decodeResource(ctx.getResources(), //large drawable);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(ctx)
            .setSmallIcon(icon)
            .setLargeIcon(bm)
            .setContentTitle(content)
            .setContentText(text)
            .setAutoCancel(true)
            .setContentIntent(pendingIntent);

    if(!silent)
       notificationBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));

 NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(1410, notificationBuilder.build());
    }

and in onMessageReceived, call it

 @Override
public void onMessageReceived(RemoteMessage remoteMessage) {


    Log.d("Msg", "Message received [" + remoteMessage.getNotification().getBody() + "]");

    buildPushNotification(/*your param*/);
}

or follow KongJing, Is also correct as he says, but you can use a Firebase Console.

As mentioned by others, you can compute the AUC using the ROCR package. With the ROCR package you can also plot the ROC curve, lift curve and other model selection measures.

You can compute the AUC directly without using any package by using the fact that the AUC is equal to the probability that a true positive is scored greater than a true negative.

For example, if pos.scores is a vector containing a score of the positive examples, and neg.scores is a vector containing the negative examples then the AUC is approximated by:

> mean(sample(pos.scores,1000,replace=T) > sample(neg.scores,1000,replace=T))
[1] 0.7261

will give an approximation of the AUC. You can also estimate the variance of the AUC by bootstrapping:

> aucs = replicate(1000,mean(sample(pos.scores,1000,replace=T) > sample(neg.scores,1000,replace=T)))

yes, you're on the right track.

yes, square brackets are the usual indicator for optional items.

Typically, as you have sketched out, there is a commandline summary at the top, followed by details, ideally with samples for each option. (Your example shows lines in between each option description, but I assume that is an editing issue, and that your real program outputs indented option listings with no blank lines in between. This would be the standard to follow in any case.)

A newer trend, (maybe there is a POSIX specification that addresses this?), is the elimination of the man page system for documentation, and including all information that would be in a manpage as part of the program --help output. This extra will include longer descriptions, concepts explained, usage samples, known limitations and bugs, how to report a bug, and possibly a 'see also' section for related commands.

I hope this helps.

Do you mean this:

if (newStr4.startsWith("Mon") || newStr4.startsWith("Tues") || ...)

Or you could use regular expression:

if (newStr4.matches("(Mon|Tues|Wed|Thurs|Fri).*"))

I use this simple code:

//reset form 
$("#mybutton").click(function(){
    $("#myform").find('input:text, input:password, input:file, select, textarea').val('');
    $("#myform").find('input:radio, input:checkbox').removeAttr('checked').removeAttr('selected');
});

Note:
to remove, delete, or uninstall nvm - just remove the $NVM_DIR folder (usually ~/.nvm)
you can try :
rm -rf ~/.nvm

If you are not using GCE or EKS (you used kubeadm) you can add an externalIPs spec to your service YAML. You can use the IP associated with your node's primary interface such as eth0. You can then access the service externally, using the external IP of the node.

...
spec:
  type: LoadBalancer
  externalIPs:
  - 192.168.0.10

This seems to work just fine:

import sys
print sys._getframe().f_back.f_code.co_name

Maybe this way:

def myTrunc(theNumber, theDigits):

    myDigits = 10 ** theDigits
    return (int(theNumber * myDigits) / myDigits)

This is simply an inefficient use of SQL, no matter how you do it.

perhaps something like

right('XXXXXXXXXXXX'+ rtrim(@str), @n)

where X is your padding character and @n is the number of characters in the resulting string (assuming you need the padding because you are dealing with a fixed length).

But as I said you should really avoid doing this in your database.

If you only need the first row from each group we can do with drop_duplicates, Notice the function default method keep='first'.

df.drop_duplicates('id')
Out[1027]: 
    id   value
0    1   first
3    2   first
5    3   first
9    4  second
11   5   first
12   6   first
15   7  fourth

Follow the code below exactly matched with your case.

1. Create an interface of the web element for the div under div with class as facetContainerDiv

ie for

<div class="facetContainerDiv">
    <div>

    </div>
</div>

2. Create an IList with all the elements inside the second div i.e for,

<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>

3. Access each check boxes using the index

            int RowCount = AllCheckBoxes.Count;
            for (int i = 0; i < RowCount; i++)
            {
            // Check the check boxes based on index
               AllCheckBoxes[i].Click();

            }
            Console.WriteLine(RowCount);
            Console.ReadLine(); 

        }

To change a document of separate lines into a single line, with each line forming one entry in a comma separated list:

1. ctrl+f to open the search/replacer.
2. Click the "Replace" tab.
3. Fill the "Find what" entry with "\r\n".
4. Fill the "Replace with" entry with "," or ", " (depending on preference).
5. Un-check the "Match whole word" checkbox (the important bit that eludes logic).
6. Check the "Extended" radio button.
7. Click the "Replace all" button.

These steps turn e.g.

foo bar

bar baz

baz foo

into:

foo bar,bar baz,baz foo

or: (depending on preference)

foo bar, bar baz, baz foo

Make sure your id_rsa file doesn't have any extension like .txt or .rtf. Rich Text Format adds additional characters to your file and those gets added to byte array. Which eventually causes invalid private key error. Long story short, Copy the file, not content.

You need to use at least Gradle 3.4 or newer to be able to use implementation. It is not recommended to keep using the deprecated compile since this can result in slower build times. For more details see the official android developer guide:

When your module configures an implementation dependency, it's letting Gradle know that the module does not want to leak the dependency to other modules at compile time. That is, the dependency is available to other modules only at runtime. Using this dependency configuration instead of api or compile can result in significant build time improvements because it reduces the amount of projects that the build system needs to recompile. For example, if an implementation dependency changes its API, Gradle recompiles only that dependency and the modules that directly depend on it. Most app and test modules should use this configuration.

https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html#new_configurations

Update: compile will be removed by end of 2018, so make sure that you use only implementation now:

Warning:Configuration 'compile' is obsolete and has been replaced with 'implementation'. It will be removed at the end of 2018

I was getting the same error while trying to browse the NuGet Package, to resolve the same followed below step

1- go to %appdata%\NuGet\NuGet.config

2- Verify the urls mentioned in that config

3- Remove the url which is not required

4- Restart visual studio and check

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

The compiler declares the variable in a way that makes it highly prone to an error that is often difficult to find and debug, while producing no perceivable benefits.

Your criticism is entirely justified.

I discuss this problem in detail here:

Closing over the loop variable considered harmful

Is there something you can do with foreach loops this way that you couldn't if they were compiled with an inner-scoped variable? or is this just an arbitrary choice that was made before anonymous methods and lambda expressions were available or common, and which hasn't been revised since then?

The latter. The C# 1.0 specification actually did not say whether the loop variable was inside or outside the loop body, as it made no observable difference. When closure semantics were introduced in C# 2.0, the choice was made to put the loop variable outside the loop, consistent with the "for" loop.

I think it is fair to say that all regret that decision. This is one of the worst "gotchas" in C#, and we are going to take the breaking change to fix it. In C# 5 the foreach loop variable will be logically inside the body of the loop, and therefore closures will get a fresh copy every time.

The for loop will not be changed, and the change will not be "back ported" to previous versions of C#. You should therefore continue to be careful when using this idiom.

We can resolve this problem in Spring-Apache-tomcat environment by adding one single line in RequestInterceptor method -

//before the actual handler will be executed
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler)
throws Exception {

// Some logic

// below statement ensures IE trusts the page formatting and will render it acc. to IE 8 standard.
response.addHeader("X-UA-Compatible", "IE=8"); 

return true;
}

Reference from - How to create filter and modify response header It covers how we can resolve this problem via a RequestInterceptor (Spring).

I think you're just looking for the overload which takes another Collector to specify what to do with each group... and then Collectors.counting() to do the counting:

import java.util.*;
import java.util.stream.*;

class Test {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();

        list.add("Hello");
        list.add("Hello");
        list.add("World");

        Map<String, Long> counted = list.stream()
            .collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));

        System.out.println(counted);
    }
}

Result:

{Hello=2, World=1}

(There's also the possibility of using groupingByConcurrent for more efficiency. Something to bear in mind for your real code, if it would be safe in your context.)

This is what worked for me:

python -m site --user-site

just use a jquery event listner , click event. let the class of the link is lb... i am considering body as a div as you said...

$('.lb').click(function() {
    $('#body1').show();
    $('#body').hide();
 });

Sergio:

You should use BLOB. It is pretty straighforward with JDBC.

The problem with the second code you posted is the encoding. You should additionally encode the bytes to make sure none of them fails.

If you still want to write it down into a String you can encode the bytes using java.util.Base64.

Still you should use CLOB as data type because you don't know how long the serialized data is going to be.

Here is a sample of how to use it.

import java.util.*;
import java.io.*;

/** 
 * Usage sample serializing SomeClass instance 
 */
public class ToStringSample {

    public static void main( String [] args )  throws IOException,
                                                      ClassNotFoundException {
        String string = toString( new SomeClass() );
        System.out.println(" Encoded serialized version " );
        System.out.println( string );
        SomeClass some = ( SomeClass ) fromString( string );
        System.out.println( "\n\nReconstituted object");
        System.out.println( some );


    }

    /** Read the object from Base64 string. */
   private static Object fromString( String s ) throws IOException ,
                                                       ClassNotFoundException {
        byte [] data = Base64.getDecoder().decode( s );
        ObjectInputStream ois = new ObjectInputStream( 
                                        new ByteArrayInputStream(  data ) );
        Object o  = ois.readObject();
        ois.close();
        return o;
   }

    /** Write the object to a Base64 string. */
    private static String toString( Serializable o ) throws IOException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream( baos );
        oos.writeObject( o );
        oos.close();
        return Base64.getEncoder().encodeToString(baos.toByteArray()); 
    }
}

/** Test subject. A very simple class. */ 
class SomeClass implements Serializable {

    private final static long serialVersionUID = 1; // See Nick's comment below

    int i    = Integer.MAX_VALUE;
    String s = "ABCDEFGHIJKLMNOP";
    Double d = new Double( -1.0 );
    public String toString(){
        return  "SomeClass instance says: Don't worry, " 
              + "I'm healthy. Look, my data is i = " + i  
              + ", s = " + s + ", d = " + d;
    }
}

Output:

It somewhat depends on what you use as a CGI framework, but they are available in dictionaries accessible to the program. I'd point you to the docs, but I'm not getting through to python.org right now. But this note on mail.python.org will give you a first pointer. Look at the CGI and URLLIB Python libs for more.

Update

Okay, that link busted. Here's the basic wsgi ref

Try use it:

Uri uri =  Uri.fromFile(entry);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
String mime = "*/*";
MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
if (mimeTypeMap.hasExtension(
    mimeTypeMap.getFileExtensionFromUrl(uri.toString())))
    mime = mimeTypeMap.getMimeTypeFromExtension(
        mimeTypeMap.getFileExtensionFromUrl(uri.toString()));
intent.setDataAndType(uri,mime);
startActivity(intent);

Keep in mind you'll also have to give the IUSR account write access for the folder once you upload to your web server.

Personally I recommend not allowing write access to the root folder unless you have a good reason for doing so. And then you need to be careful what sort of files you allow to be saved so you don't inadvertently allow someone to write their own ASPX pages.

use MYSQL as Example: 1) use database connection pools: for Example: Apache Commons DBCP , also, you need basicDataSource jar package in your classpath

@Bean
public BasicDataSource dataSource() {
    BasicDataSource ds = new BasicDataSource();
    ds.setDriverClassName("com.mysql.jdbc.Driver");
    ds.setUrl("jdbc:mysql://localhost:3306/gene");
    ds.setUsername("root");
    ds.setPassword("root");
    return ds;
}

2)use JDBC-based Driver it is usually used if you don't consider connection pool:

@Bean
public DataSource dataSource(){
    DriverManagerDataSource ds = new DriverManagerDataSource();
    ds.setDriverClassName("com.mysql.jdbc.Driver");
    ds.setUrl("jdbc:mysql://localhost:3306/gene");
    ds.setUsername("root");
    ds.setPassword("root");
    return ds;
}

Recommend using an npm package such as https://github.com/davetemplin/async-file, as compared to custom functions. For example:

import * as fs from 'async-file';

await fs.rename('/tmp/hello', '/tmp/world');
await fs.appendFile('message.txt', 'data to append');
await fs.access('/etc/passd', fs.constants.R_OK | fs.constants.W_OK);

var stats = await fs.stat('/tmp/hello', '/tmp/world');

Other answers are outdated

It can simply be done with a single reduce operation as follows;

var avg = [1,2,3,4].reduce((p,c,_,a) => p + c/a.length,0);_x000D_
console.log(avg)

I would suggest reading this for a specific answer. The conclusion of the article is that using for loop is generally better and faster than the foreach loop.

you are importing java.util package. That's why its giving error. there is a random() in java.util package too. Please remove the import statement importing java.util package. then your program will use random() method for java.lang by default and then your program will work. remember to cast it i.e

int x = (int)(Math.random()*100);

A rather simple workaround is to convert the float into string first, the select the substring of the first four numbers, finally convert the substring back to float. For example:

>>> out1 = 1.2345
>>> out1 = float(str(out1)[0:4])
>>> out1

May not be super efficient but simple and works :)

check program with this input:abc/if you got something like ab ac bc abc program works well and you need a stronger RAM otherwise the program is wrong.

Application.Exit is for Windows Forms applications - it informs all message pumps that they should terminate, waits for them to finish processing events and then terminates the application. Note that it doesn't necessarily force the application to exit.

Environment.Exit is applicable for all Windows applications, however it is mainly intended for use in console applications. It immediately terminates the process with the given exit code.

In general you should use Application.Exit in Windows Forms applications and Environment.Exit in console applications, (although I prefer to let the Main method / entry point run to completion rather than call Environment.Exit in console applications).

For more detail see the MSDN documentation.

Use regex.test() if all you want is a boolean result:

console.log(/^([a-z0-9]{5,})$/.test('abc1')); // false_x000D_
_x000D_
console.log(/^([a-z0-9]{5,})$/.test('abc12')); // true_x000D_
_x000D_
console.log(/^([a-z0-9]{5,})$/.test('abc123')); // true

...and you could remove the () from your regexp since you've no need for a capture.

On OSX (and Solaris, apparently), the mkfile command is available as well:

mkfile 10g big_file

This makes a 10 GB file named "big_file". Found this approach here.

If taskkill /F /T /PID <pid> does not work. Try opening your terminal elevated using Run as Administrator.

Search cmd in your windows menu, and right click Run as Administrator, then run the command again. This worked for me.

You need to load jquery first before bootstrap.

require.config({
    paths: {
        jquery: 'libs/jquery/jquery',
        underscore: 'libs/underscore/underscore',
        backbone: 'libs/backbone/backbone',
        bootstrap: 'libs/bootstrap',
        jquerytablesorter: 'libs/tablesorter/jquery.tablesorter',
        tablesorter: 'libs/tablesorter/tables',
        ajaxupload: 'libs/ajax-upload',
        templates: '../templates'
    },
    shim: {
        'backbone': {
            deps: ['underscore', 'jquery'],
            exports: 'Backbone'
        },
        'jquery': {
            exports: '$'
        },
        'bootstrap': {
            deps: ['jquery'],
            exports: '$'
        },
        'jquerytablesorter': {
            deps: ['jquery'],
            exports: '$'
        },
        'tablesorter': {
            deps: ['jquery'],
            exports: '$'
        },
        'ajaxupload': {
            deps: ['jquery'],
            exports: '$'
        },
        'underscore': {
            exports: '_'
        },
    }
});
require(['app', ], function(App) {
    App.initialize();
});

Works like charm! quick and easy fix.

ALTER SCHEMA NewSchema TRANSFER [OldSchema].[TableName]

I always have to use the brackets when I use the ALTER SCHEMA query in SQL, or I get an error message.

Label without an onclick will behave as you would expect. It changes the input. What you relly want is to execute selectAll() when you click on a label, right? Then only add select all to the label onclick. Or wrap the input into the the label and assign onclick only for the label

<label for="check_all_1" onclick="selectAll(document.wizard_form, this);">
  <input type="checkbox" id="check_all_1" name="check_all_1" title="Select All">
  Select All
</label>

If you are using the windows CMD you can use this command to create a database using sqlite3

C:\sqlite3.exe DBNAME.db ".read DBSCRIPT.sql"

If you haven't a database with that name sqlite3 will create one, and if you already have one, it will run it anyways but with the "TABLENAME already exists" error, I think you can also use this command to change an already existing database (but im not sure)

The problem can be solved in O(n^2) by extending the 2-sum problem with minor modifications.A is the vector containing elements and B is the required sum.

int Solution::threeSumClosest(vector &A, int B) {

sort(A.begin(),A.end());

int k=0,i,j,closest,val;int diff=INT_MAX;

while(k<A.size()-2)
{
    i=k+1;
    j=A.size()-1;

    while(i<j)
    {
        val=A[i]+A[j]+A[k];
        if(val==B) return B;
        if(abs(B-val)<diff)
        {
            diff=abs(B-val);
            closest=val;
        }
        if(B>val)
        ++i;
        if(B<val) 
        --j;
    }
    ++k;

}
return closest;

Just offering an alternative as I had this problem and none of the other answers here had the desired effect I wanted. So instead I used a list. Now semantically the information I was outputting could have been regarded as both tabular data but also listed data.

So in the end what I did was:

<ul>
    <li class="group">
        <span class="title">...</span>
        <span class="description">...</span>
        <span class="mp3-player">...</span>
        <span class="download">...</span>
        <span class="shortlist">...</span>
    </li>
    <!-- looped <li> -->
</ul>

So basically ul is table, li is tr, and span is td.

Then in CSS I set the span elements to be display:block; and float:left; (I prefer that combination to inline-block as it'll work in older versions of IE, to clear the float effect see: http://css-tricks.com/snippets/css/clear-fix/) and to also have the ellipses:

span {
    display: block;
    float: left;
    width: 100%;

    // truncate when long
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
}

Then all you do is set the max-widths of your spans and that'll give the list an appearance of a table.

If you want a real database default value, use columnDefinition:

@Column(name = "myColumn", nullable = false, columnDefinition = "int default 100") 

Notice that the string in columnDefinition is database dependent. Also if you choose this option, you have to use dynamic-insert, so Hibernate doesn't include columns with null values on insert. Otherwise talking about default is irrelevant.

But if you don't want database default value, but simply a default value in your Java code, just initialize your variable like that - private Integer myColumn = 100;

If the project is maven placed it in src/main/resources, in the package phase it will copy it in ../WEB-INF/classes/hibernate.cfg.xml

I'm also new to Eclipse, and I've been having a similar problem where Eclipse just won't recognize an import statement, even though all signs point to the dependency having been successfully downloaded.

You should check that your dependency file has actually been downloaded by going to the command line and typing

mvn dependency:tree

If you see your package there, then but Eclipse doesn't acknowledge it, the thing that works for me (sometimes) is to go to the terminal, cd into the project folder, and type

mvn eclipse:clean then mvn eclipse:eclipse

Finally refresh project in eclipse

I don't know why this works, and sometimes it doesn't work once, then doing it again does work... so worth a try!

To execute a binary or .run file in Linux from the shell, use the dot forward slash friend

 ./binary_file_name

and if it fails say because of permissions, you could try this before executing it

 chmod +x binary_file_name
 # then execute it
 ./binary_file_name

Hope it helps

You are missing router exports module and that is the reason why this error is present.

use module.exports = router; and that would work

Just for the record, I got borders in the table and to get rid of it I needed to set following properties in the GridView:

I've found pickling confusing (possibly because I'm thick). I found that this works, though:

myDictionaryString=str(myDictionary)

Which you can then write to a text file. I gave up trying to use pickle as I was getting errors telling me to write integers to a .dat file. I apologise for not using pickle.

Short Answer:

• res.setHeaders - calls the native Node.js method

• res.set - sets headers

• res.headers - an alias to res.set

In my case this was because a file named ociw32.dll had been placed in c:\windows\system32. This is however only allowed to exist in c:\oracle\11.2.0.3\bin.

Deleting the file from system32, which had been placed there by an installation of Crystal Reports, fixed this issue

use the get method in the url. If you want to pass over a variable called 'phone' as 0001112222:

<a href='whatever.php?phone=0001112222'>click</a>

then on the next page (whatever.php) you can access this var via:

$_GET['phone']

This is the strict not equal operator and only returns a value of true if both the operands are not equal and/or not of the same type. The following examples return a Boolean true:

a !== b
a !== "2"
4 !== '4' 

If you want to have your arguments C style (array of arguments + number of arguments) you can use $@ and $#.

$# gives you the number of arguments.
$@ gives you all arguments. You can turn this into an array by args=("$@").

So for example:

args=("$@")
echo $# arguments passed
echo ${args[0]} ${args[1]} ${args[2]}

Note that here ${args[0]} actually is the 1st argument and not the name of your script.

This worked for me: conda install --force-reinstall pyqt qt
Based on this

You probably haven't added a reference to Microsoft XML (any version) for Dim objHTTP As New MSXML2.XMLHTTP in the VBA window's Tools/References... dialog.

Also, it's a good idea to avoid using late binding (CreateObject...); better to use early binding (Dim objHTTP As New MSXML2.XMLHTTP), as early binding allows you to use Intellisense to list the members and do all sorts of design-time validation.

This is because the shell script is formatted in windows we need to change to unix format. You can run the dos2unix command on any Linux system.

dos2unix your-file.sh

If you don’t have access to a Linux system, you may use the Git Bash for Windows which comes with a dos2unix.exe

dos2unix.exe your-file.sh 

It seems that Luiggi Mendoza and joey rohan both already answered this, but I think it can be clarified a little.

You can write it as a single if statement:

if (inventory.contains("bread") && !inventory.contains("water")) {
    // do something
}

set a value to a variable and call invalidateOptionsMenu();

for example

    selectedid=arg2;
            invalidateOptionsMenu();


 public boolean onPrepareOptionsMenu(Menu menu) {

    if(selectedid==1){
        menu.findItem(R.id.action_setting).setVisible(false);
        menu.findItem(R.id.action_s2).setVisible(false);
        menu.findItem(R.id.action_s3).setVisible(false);
    }
    else{
        if(selectedid==2){
            menu.findItem(R.id.action_search).setVisible(false);
            menu.findItem(R.id.action_s4).setVisible(false);
            menu.findItem(R.id.action_s5).setVisible(false);
        }
    }
    return super.onPrepareOptionsMenu(menu);
}

Keep a look out for SQL Server to support the 'INSERT ALL' Statement. Oracle has it already, it looks like this (SQL Cookbook):

insert all
  when loc in ('NEW YORK', 'BOSTON') THEN
   into dept_east(deptno, dname, loc) values(deptno, dname, loc)
  when loc in ('CHICAGO') THEN
   into dept_mid(deptno, dname, loc) values(deptno, dname, loc)
  else
   into dept_west(deptno, dname, loc) values(deptno, dname, loc)
select deptno, dname, loc
  from dept

I was facing this issue and fixed by putting a check in form attribute. This issue can happen when the FormGroup is not initialized.

<form [formGroup]="loginForm" *ngIf="loginForm">
OR
<form [formGroup]="loginForm" *ngIf="this.loginForm">

This will not render the form until it is initialized.

This is how you do it:

function view($view)
{
    $ms = Person::where('name', '=', 'Foo Bar')->first();

    $persons = Person::order_by('list_order', 'ASC')->get();

    return $view->with('persons', $persons)->with('ms', $ms);
}

You can also use compact():

function view($view)
{
    $ms = Person::where('name', '=', 'Foo Bar')->first();

    $persons = Person::order_by('list_order', 'ASC')->get();

    return $view->with(compact('persons', 'ms'));
}

Or do it in one line:

function view($view)
{
    return $view
            ->with('ms', Person::where('name', '=', 'Foo Bar')->first())
            ->with('persons', Person::order_by('list_order', 'ASC')->get());
}

Or even send it as an array:

function view($view)
{
    $ms = Person::where('name', '=', 'Foo Bar')->first();

    $persons = Person::order_by('list_order', 'ASC')->get();

    return $view->with('data', ['ms' => $ms, 'persons' => $persons]));
}

But, in this case, you would have to access them this way:

{{ $data['ms'] }}

Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties to set a default date format to all of your classes spring.jackson.date-format.

For your date format example, you would add this line to your properties file:

spring.jackson.date-format=yyyy-MM-dd

Reference https://docs.spring.io/spring-boot/docs/1.2.0.RELEASE/reference/html/common-application-properties.html

Use spread operator and some ES6 here

this.setState({
    jasper: {
          ...this.state.jasper,
          name: 'something'
    }
})

Is your repository at "upstream" a bare repository? I got the same error, but when I change to bare they no longer happen.

As others have pointed out, the accepted answer does not return both x86 and x64 installs. Below is my solution for that. It creates a StringBuilder, appends the registry values to it (with formatting), and writes its output to a text file:

const string FORMAT = "{0,-100} {1,-20} {2,-30} {3,-8}\n";

private void LogInstalledSoftware()
{
    var line = string.Format(FORMAT, "DisplayName", "Version", "Publisher", "InstallDate");
    line += string.Format(FORMAT, "-----------", "-------", "---------", "-----------");
    var sb = new StringBuilder(line, 100000);
    ReadRegistryUninstall(ref sb, RegistryView.Registry32);
    sb.Append($"\n[64 bit section]\n\n{line}");
    ReadRegistryUninstall(ref sb, RegistryView.Registry64);
    File.WriteAllText(@"c:\temp\log.txt", sb.ToString());
}

   private static void ReadRegistryUninstall(ref StringBuilder sb, RegistryView view)
    {
        const string REGISTRY_KEY = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
        using var baseKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, view);
        using var subKey = baseKey.OpenSubKey(REGISTRY_KEY);
        foreach (string subkey_name in subKey.GetSubKeyNames())
        {
            using RegistryKey key = subKey.OpenSubKey(subkey_name);
            if (!string.IsNullOrEmpty(key.GetValue("DisplayName") as string))
            {
                var line = string.Format(FORMAT,
                    key.GetValue("DisplayName"),
                    key.GetValue("DisplayVersion"),
                    key.GetValue("Publisher"),
                    key.GetValue("InstallDate"));
                sb.Append(line);
            }
            key.Close();
        }
        subKey.Close();
        baseKey.Close();
    }

In Postgres, you can also use the special DISTINCT ON (expression) syntax:

SELECT DISTINCT ON (cname) 
    cname, wmname, avg
FROM 
    makerar 
ORDER BY 
    cname, avg DESC ;

Just to throw my two cents in: another common cause of this error in my experience is code in the Form_Resize event that uses math to resize controls on a form. Control dimensions (Height and Width) can't be set to negative values, so code like the following in your Form_Resize event can cause this error:

Private Sub Form_Resize()
    'Resize text box to fit the form, with a margin of 1000 twips on the right.'
    'This will error out if the width of the Form drops below 1000 twips.'
    txtFirstName.Width = Me.Width - 1000
End Sub

The above code will raise an an "Invalid property value" error if the form is resized to less than 1000 twips wide. If this is the problem, the easiest solution is to add On Error Resume Next as the first line, so that these kinds of errors are ignored. This is one of those rare situations in VB6 where On Error Resume Next is your friend.

Here is an example of a parent List react component and whos props contain a react element. In this case, just a single Link react component is passed in (as seen in the dom render).

class Link extends React.Component {
  constructor(props){
    super(props);
  }
  render(){
    return (
      <div>
        <p>{this.props.name}</p>
      </div>
     );
  }
}
class List extends React.Component {
  render(){
   return(
    <div>
       {this.props.element}
       {this.props.element}
    </div>
   );
  }
}

ReactDOM.render(
  <List element = {<Link name = "working"/>}/>,
  document.getElementById('root')
);

htmlspecialchars function is the best solution fellows. Today I was searching for how to insert strings with special characters and the google thrown so many Stackoverflow listings.None of them provided me solution. I found it in w3schools page. Yes I could solve my problem by using this function like this:

$abc = $POST['xyz'];

$abc = htmlspecialchars($abc);

I ran into this problem due to the missing:

-vmargs -javaagent:lombok.jar -Xbootclasspath/a:lombok.jar

as well. What is not explicitly said neither here nor in the Lombok popup message, and was not obvious to me as someone who never before had to fiddle with the eclipse.ini, is that you are NOT supposed to add that line, but instead add the last two parts of that line after the first part, which is already in the eclipse.ini file. To better illustrate, the end of the file should look something like this (bold is what matters for Lombok, the rest might be different for you):

-vm
C:/Program Files/Java/jdk1.7.0_02/bin
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx384m
-javaagent:lombok.jar
-Xbootclasspath/a:lombok.jar

**To avoid XSS security threat in spring application**

solution to the XSS issue is to filter all the textfields in the form at the time of submitting the form.

    It needs XML entry in the web.xml file & two simple classes.

        java code :-
        The code for the  first class named CrossScriptingFilter.java is :

        package com.filter;

        import java.io.IOException;
        import javax.servlet.Filter;
        import javax.servlet.FilterChain;
        import javax.servlet.FilterConfig;
        import javax.servlet.ServletException;
        import javax.servlet.ServletRequest;
        import javax.servlet.ServletResponse;
        import javax.servlet.http.HttpServletRequest;
        import org.apache.log4j.Logger;

        public class CrossScriptingFilter implements Filter {
            private static Logger logger = Logger.getLogger(CrossScriptingFilter.class);
            private FilterConfig filterConfig;

            public void init(FilterConfig filterConfig) throws ServletException {
                this.filterConfig = filterConfig;
            }

            public void destroy() {
                this.filterConfig = null;
            }

            public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {
                logger.info("Inlter CrossScriptingFilter  ...............");
                chain.doFilter(new RequestWrapper((HttpServletRequest) request), response);
                logger.info("Outlter CrossScriptingFilter ...............");
            }

        }

The code second class named RequestWrapper.java is :

package com.filter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;

import org.apache.log4j.Logger;

public final class RequestWrapper extends HttpServletRequestWrapper {
    private static Logger logger = Logger.getLogger(RequestWrapper.class);
    public RequestWrapper(HttpServletRequest servletRequest) {
        super(servletRequest);
    }

    public String[] getParameterValues(String parameter) {
        logger.info("InarameterValues .. parameter .......");
        String[] values = super.getParameterValues(parameter);
        if (values == null) {
            return null;
        }
        int count = values.length;
        String[] encodedValues = new String[count];
        for (int i = 0; i < count; i++) {
            encodedValues[i] = cleanXSS(values[i]);
        }
        return encodedValues;
    }

    public String getParameter(String parameter) {
        logger.info("Inarameter .. parameter .......");
        String value = super.getParameter(parameter);
        if (value == null) {
            return null;
        }
        logger.info("Inarameter RequestWrapper ........ value .......");
        return cleanXSS(value);
    }

    public String getHeader(String name) {
        logger.info("Ineader .. parameter .......");
        String value = super.getHeader(name);
        if (value == null)
            return null;
        logger.info("Ineader RequestWrapper ........... value ....");
        return cleanXSS(value);
    }

    private String cleanXSS(String value) {
        // You'll need to remove the spaces from the html entities below
        logger.info("InnXSS RequestWrapper ..............." + value);
        //value = value.replaceAll("<", "& lt;").replaceAll(">", "& gt;");
        //value = value.replaceAll("\\(", "& #40;").replaceAll("\\)", "& #41;");
        //value = value.replaceAll("'", "& #39;");
        value = value.replaceAll("eval\\((.*)\\)", "");
        value = value.replaceAll("[\\\"\\\'][\\s]*javascript:(.*)[\\\"\\\']", "\"\"");

        value = value.replaceAll("(?i)<script.*?>.*?<script.*?>", "");
        value = value.replaceAll("(?i)<script.*?>.*?</script.*?>", "");
        value = value.replaceAll("(?i)<.*?javascript:.*?>.*?</.*?>", "");
        value = value.replaceAll("(?i)<.*?\\s+on.*?>.*?</.*?>", "");
        //value = value.replaceAll("<script>", "");
        //value = value.replaceAll("</script>", "");
        logger.info("OutnXSS RequestWrapper ........ value ......." + value);
        return value;
    }

The only thing remained is the XML entry in the web.xml file:

        <filter>
        <filter-name>XSS</filter-name>
        <display-name>XSS</display-name>
        <description></description>
        <filter-class>com.filter.CrossScriptingFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>XSS</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

The /* indicates that for every request made from browser, it will call CrossScriptingFilter class. Which will parse all the components/elements came from the request & will replace all the javascript tags put by hacker with empty string i.e

This always works, either one should be just fine:

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    Button btn = (Button) findViewById(R.id.button1);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick (View v) {
            startActivity(new Intent("com.tobidae.Activity1"));
        }
        //** OR you can just use the one down here instead, both work either way
        @Override
        public void onClick (View v){
            Intent i = new Intent(getApplicationContext(), ChemistryActivity.class);
            startActivity(i);
        }
    }
}

The error message I was getting was similar but the reason was that the self signed certificate had expired. When the openssl client was attempted, it gave me the reason which was overlooked when I was checking the certificate dialog from firefox.

So in general, if the certificate is there in the keystore and its "VALID", this error will go off.

Just write

System.Diagnostics.Process.Start(@"file path");

example

System.Diagnostics.Process.Start(@"C:\foo.jpg");
System.Diagnostics.Process.Start(@"C:\foo.doc");
System.Diagnostics.Process.Start(@"C:\foo.dxf");
...

And shell will run associated program reading it from the registry, like usual double click does.

I extended PDO to do something similar to what stefs suggests, and it was easier for me in the long run:

class Array_Capable_PDO extends PDO {
    /**
     * Both prepare a statement and bind array values to it
     * @param string $statement mysql query with colon-prefixed tokens
     * @param array $arrays associatve array with string tokens as keys and integer-indexed data arrays as values 
     * @param array $driver_options see php documention
     * @return PDOStatement with given array values already bound 
     */
    public function prepare_with_arrays($statement, array $arrays, $driver_options = array()) {

        $replace_strings = array();
        $x = 0;
        foreach($arrays as $token => $data) {
            // just for testing...
            //// tokens should be legit
            //assert('is_string($token)');
            //assert('$token !== ""');
            //// a given token shouldn't appear more than once in the query
            //assert('substr_count($statement, $token) === 1');
            //// there should be an array of values for each token
            //assert('is_array($data)');
            //// empty data arrays aren't okay, they're a SQL syntax error
            //assert('count($data) > 0');

            // replace array tokens with a list of value tokens
            $replace_string_pieces = array();
            foreach($data as $y => $value) {
                //// the data arrays have to be integer-indexed
                //assert('is_int($y)');
                $replace_string_pieces[] = ":{$x}_{$y}";
            }
            $replace_strings[] = '('.implode(', ', $replace_string_pieces).')';
            $x++;
        }
        $statement = str_replace(array_keys($arrays), $replace_strings, $statement);
        $prepared_statement = $this->prepare($statement, $driver_options);

        // bind values to the value tokens
        $x = 0;
        foreach($arrays as $token => $data) {
            foreach($data as $y => $value) {
                $prepared_statement->bindValue(":{$x}_{$y}", $value);
            }
            $x++;
        }

        return $prepared_statement;
    }
}

You can use it like this:

$db_link = new Array_Capable_PDO($dsn, $username, $password);

$query = '
    SELECT     *
    FROM       test
    WHERE      field1 IN :array1
     OR        field2 IN :array2
     OR        field3 = :value
';

$pdo_query = $db_link->prepare_with_arrays(
    $query,
    array(
        ':array1' => array(1,2,3),
        ':array2' => array(7,8,9)
    )
);

$pdo_query->bindValue(':value', '10');

$pdo_query->execute();

It is one of the annotation used to map/handle dynamic URIs. You can even specify a regular expression for URI dynamic parameter to accept only specific type of input.

For example, if the URL to retrieve a book using a unique number would be:

URL:http://localhost:8080/book/9783827319333

The number denoted at the last of the URL can be fetched using @PathVariable as shown:

@RequestMapping(value="/book/{ISBN}", method= RequestMethod.GET)

public String showBookDetails(@PathVariable("ISBN") String id,

Model model){

model.addAttribute("ISBN", id);

return "bookDetails";

}

In short it is just another was to extract data from HTTP requests in Spring.

If you are not using UICollectionViewController, you need to add conformance to it by setting delegates UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout.

  extension ViewController: UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout

After that, you have to set a delegate to your collection view that is added to ViewController.

  collectionView.delegate = self
  collectionView.dataSource = self


  

And finally, you have to add layout to your collection view:

  let collectionLayout = UICollectionViewFlowLayout()
  collectionView.collectionViewLayout = collectionLayout

After these steps, you can change size in func:

  func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize

You can store any kind of data in a session using:

Session["VariableName"]=value;

This variable will last 20 mins or so.

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20

You can do both in one if you use index

<div *ngFor="let item of items; let myIndex = index>
  {{myIndex}}
</div>

With this you can get the best of both worlds.

What about anonymous fields? I'm not sure if that will constitute a "nested struct" but it's cleaner than having a nested struct declaration. What if you want to reuse the nested element elsewhere?

type NestedElement struct{
    someNumber int `json:"number"`
    someString string `json:"string"`
}

type BaseElement struct {
    NestedElement `json:"bar"`
}

This worked for me

<p:column headerText="name" style="width:20px;"/>

Building upon the fiddle from @tim, this version tightens the scope and formatting, and converts bind() -> on(). It's designed to bind on a dedicated td as the handle instead of the entire row. In my use case, I have input fields so the "drag anywhere on the row" approach felt confusing.

Tested working on desktop. Only partial success with mobile touch. Can't get it to run correctly on SO's runnable snippet for some reason...

let ns = {
  drag: (e) => {
    let el = $(e.target),
      d = $('body'),
      tr = el.closest('tr'),
      sy = e.pageY,
      drag = false,
      index = tr.index();

    tr.addClass('grabbed');

    function move(e) {
      if (!drag && Math.abs(e.pageY - sy) < 10)
        return;
      drag = true;
      tr.siblings().each(function() {
        let s = $(this),
          i = s.index(),
          y = s.offset().top;
        if (e.pageY >= y && e.pageY < y + s.outerHeight()) {
          i < tr.index() ? s.insertAfter(tr) : s.insertBefore(tr);
          return false;
        }
      });
    }

    function up(e) {
      if (drag && index !== tr.index())
        drag = false;

      d.off('mousemove', move).off('mouseup', up);
      //d.off('touchmove', move).off('touchend', up); //failed attempt at touch compatibility
      tr.removeClass('grabbed');
    }
    d.on('mousemove', move).on('mouseup', up);
    //d.on('touchmove', move).on('touchend', up);
  }

I added the following 2 parameters: /np /nfl

So together with the 5 parameters from AndyGeek's answer, which are /njh /njs /ndl /nc /ns you get the following and it's silent:

ROBOCOPY [source] [target] /NFL /NDL /NJH /NJS /nc /ns /np

/NFL : No File List - don't log file names.
/NDL : No Directory List - don't log directory names.
/NJH : No Job Header.
/NJS : No Job Summary.
/NP  : No Progress - don't display percentage copied.
/NS  : No Size - don't log file sizes.
/NC  : No Class - don't log file classes.

If you're dealing with very large strings, specifically multiline strings, be aware of the triple-quote syntax:

a = r"""This is a multiline string
with more than one line
in the source code."""

We can't talk about virtual members without referring to polymorphism. In fact, a function, property, indexer or event in a base class marked as virtual will allow override from a derived class.

By default, members of a class are non-virtual and cannot be marked as that if static, abstract, private, or override modifiers.

Example Let's consider the ToString() method in System.Object. Because this method is a member of System.Object it's inherited in all classes and will provide the ToString() methods to all of them.

namespace VirtualMembersArticle
{
    public class Company
    {
        public string Name { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Company company = new Company() { Name = "Microsoft" };
            Console.WriteLine($"{company.ToString()}");
            Console.ReadLine();
        }   
    }
}

The output of the previous code is:

VirtualMembersArticle.Company

Let's consider that we want to change the standard behavior of the ToString() methods inherited from System.Object in our Company class. To achieve this goal it's enough to use the override keyword to declare another implementation of that method.

public class Company
{
    ...
    public override string ToString()
    {
        return $"Name: {this.Name}";
    }         
}

Now, when a virtual method is invoked, the run-time will check for an overriding member in its derived class and will call it if present. The output of our application will then be:

Name: Microsoft

In fact, if you check the System.Object class you will find that the method is marked as virtual.

namespace System
{
    [NullableContextAttribute(2)]
    public class Object
    {
        ....
        public virtual string? ToString();
        ....
    }
}

The highly regarded Joda Time library is also worth a look. This is basis for the new date and time api that is pencilled in for Java 7. The design is neat, intuitive, well documented and avoids a lot of the clumsiness of the original java.util.Date / java.util.Calendar classes.

Joda's DateFormatter can parse a String to a Joda DateTime.

Replace 123 with number of commits your branch has diverged from origin.

git reset HEAD~123 && git reset && git checkout . && git clean -fd && git pull

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

This command should work:

sed "s/\s/,/g" < infile.txt > outfile.txt

Note that you have to redirect the output to a new file. The input file is not changed in place.

In Android M the top solution won't work. I've written a helper class to fix that which you should call from your Application class and all Activities (I would suggest creating a BaseActivity and then make all the Activities inherit from it.

Note: This will also support properly RTL layout direction.

Helper class:

public class LocaleUtils {

    private static Locale sLocale;

    public static void setLocale(Locale locale) {
        sLocale = locale;
        if(sLocale != null) {
            Locale.setDefault(sLocale);
        }
    }

    public static void updateConfig(ContextThemeWrapper wrapper) {
        if(sLocale != null && Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            Configuration configuration = new Configuration();
            configuration.setLocale(sLocale);
            wrapper.applyOverrideConfiguration(configuration);
        }
    }

    public static void updateConfig(Application app, Configuration configuration) {
        if (sLocale != null && Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
            //Wrapping the configuration to avoid Activity endless loop
            Configuration config = new Configuration(configuration);
            // We must use the now-deprecated config.locale and res.updateConfiguration here,
            // because the replacements aren't available till API level 24 and 17 respectively.
            config.locale = sLocale;
            Resources res = app.getBaseContext().getResources();
            res.updateConfiguration(config, res.getDisplayMetrics());
        }
    }
}

Application:

public class App extends Application {
    public void onCreate(){
        super.onCreate();

        LocaleUtils.setLocale(new Locale("iw"));
        LocaleUtils.updateConfig(this, getBaseContext().getResources().getConfiguration());
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        LocaleUtils.updateConfig(this, newConfig);
    }
}

BaseActivity:

public class BaseActivity extends Activity {
    public BaseActivity() {
        LocaleUtils.updateConfig(this);
    }
}

Now it's pretty easy to implement for RecyclerView with ItemTouchHelper. Just override onMove method from ItemTouchHelper.Callback:

 @Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
    mMovieAdapter.swap(viewHolder.getAdapterPosition(), target.getAdapterPosition());
    return true;
}

Pretty good tutorial on this can be found at medium.com : Drag and Swipe with RecyclerView

You can also try WANem which is an open source Wide Area Network emulator. You can download the image (ISO, Knoppix live CD) or VMWare virtual appliances.

From Web developer perspective:

1. Library can be easily replaceable by another library. But framework cannot.

   If you don't like jquery date picker library, you can replace with other date picker such as bootstrap date picker or pickadate.

   If you don't like AngularJS on which you built your product, you cannot just replace with any other frameworks. You have to rewrite your entire code base.

2. Mostly library takes very less learning curve compared to Frameworks. Eg: underscore.js is a library, Ember.js is a framework.

A good example of the 307 Internal Redirect in action is when Google Chrome encounters a HTTP call to a domain it knows as requiring Strict Transport Security.

The browser redirects seamlessly, using the same method as the original call.

The simplest way of doing this would be to rename the root app folder from com.example.MyApp to com.newcompanyname.MyNewAppName and then replace all occurrences of the old path to the new path in whatever IDE you're using.

In your 'head' section, add this code:

<style>
input[type='text'] { font-size: 24px; }
</style>

Or you can only add the:

input[type='text'] { font-size: 24px; }

to a CSS file which can later be included.

You can also change the font face by using the CSS property: font-family

font-family: monospace;

So you can have a CSS code like this:

input[type='text'] { font-size: 24px; font-family: monospace; }

You can find further help at the W3Schools website.

I suggest you to have a look at the CSS3 specification. With CSS3 you can also load a font from the web instead of having the limitation to use only the most common fonts or tell the user to download the font you're using.

 <View
        android:layout_width="2dp"
        android:layout_height="40dp"

        android:background="#ffffff"
        android:padding="10dp" />`

This might help:

<input type="number" step="1" pattern="\d+" />

step is for convenience (and could be set to another integer), but pattern does some actual enforcing.

Note that since pattern matches the whole expression, it wasn't necessary to express it as ^\d+$.

Even with this outwardly tight regular expression, Chrome and Firefox's implementations, interestingly allow for e here (presumably for scientific notation) as well as - for negative numbers, and Chrome also allows for . whereas Firefox is tighter in rejecting unless the . is followed by 0's only. (Firefox marks the field as red upon the input losing focus whereas Chrome doesn't let you input disallowed values in the first place.)

Since, as observed by others, one should always validate on the server (or on the client too, if using the value locally on the client or wishing to prevent the user from a roundtrip to the server).

As other posters have said, you need to change the LayoutManager being used. I always preferred using a GridLayout so your code would become:

MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new GridLayout());
mainFrame.pack();
mainFrame.setVisible(true);

GridLayout seems more conceptually correct to me when you want your panel to take up the entire screen.

@Html.Raw(Json.Encode(object)) can be used to convert the View Modal Object to JSON

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

Do:

con.query('SET GLOBAL connect_timeout=28800')
con.query('SET GLOBAL interactive_timeout=28800')
con.query('SET GLOBAL wait_timeout=28800')

Parameter meaning (taken from MySQL Workbench in Navigator: Instance > Options File > Tab "Networking" > Section "Timeout Settings")

• connect_timeout: Number of seconds the mysqld server waits for a connect packet before responding with 'Bad handshake'
• interactive_timeout Number of seconds the server waits for activity on an interactive connection before closing it
• wait_timeout Number of seconds the server waits for activity on a connection before closing it

BTW: 28800 seconds are 8 hours, so for a 10 hour execution time these values should be actually higher.

Use this 'Split' function:

CREATE OR REPLACE FUNCTION Split (p_str varchar2) return sys_refcursor is
v_res sys_refcursor;

begin
  open v_res for 
  WITH TAB AS 
  (SELECT p_str STR FROM DUAL)
  select substr(STR, instr(STR, ',', 1, lvl) + 1, instr(STR, ',', 1, lvl + 1) - instr(STR, ',', 1, lvl) - 1) name 
  from
    ( select ',' || STR || ',' as STR from TAB ),
    ( select level as lvl from dual connect by level <= 100 )
    where lvl <= length(STR) - length(replace(STR, ',')) - 1;

     return v_res;
   end;

You can't use this function in select statement like you described in question, but I hope you will find it still useful.

EDIT: Here are steps you need to do. 1. Create Object: create or replace type empy_type as object(value varchar2(512)) 2. Create Type: create or replace type t_empty_type as table of empy_type 3. Create Function:

CREATE OR REPLACE FUNCTION Split (p_str varchar2) return sms.t_empty_type is
v_emptype t_empty_type := t_empty_type();
v_cnt     number := 0;
v_res sys_refcursor;
v_value nvarchar2(128);
begin
  open v_res for
  WITH TAB AS
  (SELECT p_str STR FROM DUAL)
  select substr(STR, instr(STR, ',', 1, lvl) + 1, instr(STR, ',', 1, lvl +     1) - instr(STR, ',', 1, lvl) - 1) name
  from
    ( select ',' || STR || ',' as STR from TAB ),
    ( select level as lvl from dual connect by level <= 100 )
    where lvl <= length(STR) - length(replace(STR, ',')) - 1;


  loop
     fetch v_res into v_value;
      exit when v_res%NOTFOUND;
      v_emptype.extend;
      v_cnt := v_cnt + 1;
     v_emptype(v_cnt) := empty_type(v_value);
    end loop;
    close v_res;

    return v_emptype;
end;

Then just call like this:

SELECT * FROM (TABLE(split('a,b,c,d,g')))

Use the Date.prototype.setFullYear method to set the year to what you want it to be.

For example:

var aYearFromNow = new Date();
aYearFromNow.setFullYear(aYearFromNow.getFullYear() + 1);

There really isn't another way to work with dates in JavaScript if these methods aren't present in the environment you are working with.

logout your account in skype.. then in xampp control panel click start from the line of Apache..

You can kill all node processes using pkill node

or you can do a ps T to see all processes on this terminal
then you can kill a specific process ID doing a kill [processID] example: kill 24491

Additionally, you can do a ps -help to see all the available options

This code work correctly only when u put into button click because at that time user put values into editable text and then when user clicks button it fetch the data and convert into string

EditText dob=(EditText)findviewbyid(R.id.edit_id);
String  str=dob.getText().toString();

Never mind -- I'm an idiot. I just needed <xsl:value-of select="/root/Image/node()"/>

This ones a little old but was high in the google ranking so I thought I would throw in the answer I found from Chrome, pdf display, Duplicate headers received from the server

Basically my problem also was that the filename contained commas. Do a replace on commas to remove them and you should be fine. My function to make a valid filename is below.

    public static string MakeValidFileName(string name)
    {
        string invalidChars = Regex.Escape(new string(System.IO.Path.GetInvalidFileNameChars()));
        string invalidReStr = string.Format(@"[{0}]+", invalidChars);
        string replace = Regex.Replace(name, invalidReStr, "_").Replace(";", "").Replace(",", "");
        return replace;
    }

You can easily do that with

git log master..branch-X

That will show you commits that branch-X has but master doesn't.

If you already know the dates then you can simply use between, like this:

SELECT id    
FROM `Mytable`    
where MyDate BETWEEN "2011-05-15" AND "2011-05-21"

It seems that it doesn't turn it into a string. Try

row.HeaderCell.Value = String.Format("{0}", row.Index + 1);

I usually start with something like:

set lines 256
set trimout on
set tab off

Have a look at help set if you have the help information installed. And then select name,address rather than select * if you really only want those two columns.

I am elaborating a bit on o.k.w.'s answer.

You can use the browser's DOM functions for that.

var utils = {
    dummy: document.createElement('div'),
    escapeHTML: function(s) {
        this.dummy.textContent = s
        return this.dummy.innerHTML
    }
}

utils.escapeHTML('<escapeThis>&')

This returns <escapeThis>&

It uses the standard function createElement to create an invisible element, then uses the function textContent to set any string as its content and then innerHTML to get the content in its HTML representation.

In short:

Files.move(source, source.resolveSibling("newname"));

More detail:

import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;

The following is copied directly from http://docs.oracle.com/javase/7/docs/api/index.html:

Suppose we want to rename a file to "newname", keeping the file in the same directory:

Path source = Paths.get("path/here");
Files.move(source, source.resolveSibling("newname"));

Alternatively, suppose we want to move a file to new directory, keeping the same file name, and replacing any existing file of that name in the directory:

Path source = Paths.get("from/path");
Path newdir = Paths.get("to/path");
Files.move(source, newdir.resolve(source.getFileName()), StandardCopyOption.REPLACE_EXISTING);

(Feature Panel).setOpaque(false);

Hope this helps.

In my case (IntelliJ 2020-02, Kotlin dev) JUnit library was already included by Create project wizard. I needed to enable JUnit plugin:

to get green Run test icons next to each test class and method:

and CTRL+Shift+R will run test under caret, and CTRL+shift+D to debug.

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

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

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

Edit: Regarding your comment:

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

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

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

   An example in ipython:

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

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

Closest you'd get to a struct is an object with all members public.

class MyStruct {
    public $foo;
    public $bar;
}

$obj = new MyStruct();
$obj->foo = 'Hello';
$obj->bar = 'World';

I'd say looking at the PHP Class Documentation would be worth it. If you need a one-off struct, use the StdObject as mentioned in alex's answer.

In case someone google for this, the solutions above didn't work for me so i ended using "pure" javascript

document.getElementById("The id of the element").value = "The value"

And that would set the value and make the current value selected in the combo box. Tested in firefox.

it was easier than keep googling a solution for jQuery

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

Do a str.replace('; ', ', ') and then a str.split(', ')

The network setup is crucial for any measurements. It makes a huge difference, if you are communicating via sockets on your local machine or with the other end of the world.

Three things I want to add to the discussion:

1. You can find here a very good article about TCP vs. UDP in the context of game development.
2. Additionally, iperf (jperf enhance iperf with a GUI) is a very nice tool for answering your question yourself by measuring.
3. I implemented a benchmark in Python (see this SO question). In average of 10^6 iterations the difference for sending 8 bytes is about 1-2 microseconds for UDP.

This is related to compact option of Babel compiler, which commands to "not include superfluous whitespace characters and line terminators. When set to 'auto' compact is set to true on input sizes of >100KB." By default its value is "auto", so that is probably the reason you are getting the warning message. See Babel documentation.

You can change this option from Webpack using a query parameter. For example:

loaders: [
    { test: /\.js$/, loader: 'babel', query: {compact: false} }
]

Try this :

pip install webdriver-manager

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())

Patching wasn't working for me, for whatever reason, so I had to resort to this method:

import { of } from 'rxjs/observable/of'

// ...

return of(res)

Updated eclipse.ini file with key-value property

-Dosgi.requiredJavaVersion=1.5 

to

-Dosgi.requiredJavaVersion=1.8

because, that is my JAVA version.

Also, selected JRE 1.8 as my project library

Simplest Answer is "No Direct method of getting it because there is no pre-compiler" But you can do it by yourself. Use classes and then define variables as final so that it can be assumed as constant throughout the program
Don't forget to use final and variable as public or protected not private otherwise you won't be able to access it from outside that class

A Json Web Token made up of three parts. The header, the payload and the signature Now the header is just some metadata about the token itself and the payload is the data that we can encode into the token, any data really that we want. So the more data we want to encode here the bigger the JWT. Anyway, these two parts are just plain text that will get encoded, but not encrypted.

So anyone will be able to decode them and to read them, we cannot store any sensitive data in here. But that's not a problem at all because in the third part, so in the signature, is where things really get interesting. The signature is created using the header, the payload, and the secret that is saved on the server.

And this whole process is then called signing the Json Web Token. The signing algorithm takes the header, the payload, and the secret to create a unique signature. So only this data plus the secret can create this signature, all right? Then together with the header and the payload, these signature forms the JWT, which then gets sent to the client.

Once the server receives a JWT to grant access to a protected route, it needs to verify it in order to determine if the user really is who he claims to be. In other words, it will verify if no one changed the header and the payload data of the token. So again, this verification step will check if no third party actually altered either the header or the payload of the Json Web Token.

So, how does this verification actually work? Well, it is actually quite straightforward. Once the JWT is received, the verification will take its header and payload, and together with the secret that is still saved on the server, basically create a test signature.

But the original signature that was generated when the JWT was first created is still in the token, right? And that's the key to this verification. Because now all we have to do is to compare the test signature with the original signature. And if the test signature is the same as the original signature, then it means that the payload and the header have not been modified.

Because if they had been modified, then the test signature would have to be different. Therefore in this case where there has been no alteration of the data, we can then authenticate the user. And of course, if the two signatures are actually different, well, then it means that someone tampered with the data. Usually by trying to change the payload. But that third party manipulating the payload does of course not have access to the secret, so they cannot sign the JWT. So the original signature will never correspond to the manipulated data. And therefore, the verification will always fail in this case. And that's the key to making this whole system work. It's the magic that makes JWT so simple, but also extremely powerful.

Now let's do some practices with nodejs:

Configuration file is perfect for storing JWT SECRET data. Using the standard HSA 256 encryption for the signature, the secret should at least be 32 characters long, but the longer the better.

config.env:

JWT_SECRET = my-32-character-ultra-secure-and-ultra-long-secret
//after 90days JWT will no longer be valid, even the signuter is correct and everything is matched.
JWT_EXPIRES_IN=90

now install JWT using command

npm i jsonwebtoken

Example after user signup passing him JWT token so he can stay logged in and get access of resources.

exports.signup = catchAsync(async (req, res, next) => {
  const newUser = await User.create({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password,
    passwordConfirm: req.body.passwordConfirm,
  });
  const token = jwt.sign({ id: newUser._id }, process.env.JWT_SECRET, {
    expiresIn: process.env.JWT_EXPIRES_IN,
  });

  res.status(201).json({
    status: 'success',
    token,
    data: {
      newUser,
    },
  });
});

output:

In my opinion, do not take help from a third-party to generate your super-secret key, because you can't say it's secret anymore. Just use your keyboard.

To capture both stdout & stderr from your docker container to a single log file run the following:

docker logs container > container.log 2>&1

How would you check if a variable is a dictionary in Python?

This is an excellent question, but it is unfortunate that the most upvoted answer leads with a poor recommendation, type(obj) is dict.

(Note that you should also not use dict as a variable name - it's the name of the builtin object.)

If you are writing code that will be imported and used by others, do not presume that they will use the dict builtin directly - making that presumption makes your code more inflexible and in this case, create easily hidden bugs that would not error the program out.

I strongly suggest, for the purposes of correctness, maintainability, and flexibility for future users, never having less flexible, unidiomatic expressions in your code when there are more flexible, idiomatic expressions.

is is a test for object identity. It does not support inheritance, it does not support any abstraction, and it does not support the interface.

So I will provide several options that do.

Supporting inheritance:

This is the first recommendation I would make, because it allows for users to supply their own subclass of dict, or a OrderedDict, defaultdict, or Counter from the collections module:

if isinstance(any_object, dict):

But there are even more flexible options.

Supporting abstractions:

from collections.abc import Mapping

if isinstance(any_object, Mapping):

This allows the user of your code to use their own custom implementation of an abstract Mapping, which also includes any subclass of dict, and still get the correct behavior.

Use the interface

You commonly hear the OOP advice, "program to an interface".

This strategy takes advantage of Python's polymorphism or duck-typing.

So just attempt to access the interface, catching the specific expected errors (AttributeError in case there is no .items and TypeError in case items is not callable) with a reasonable fallback - and now any class that implements that interface will give you its items (note .iteritems() is gone in Python 3):

try:
    items = any_object.items()
except (AttributeError, TypeError):
    non_items_behavior(any_object)
else: # no exception raised
    for item in items: ...

Perhaps you might think using duck-typing like this goes too far in allowing for too many false positives, and it may be, depending on your objectives for this code.

Conclusion

Don't use is to check types for standard control flow. Use isinstance, consider abstractions like Mapping or MutableMapping, and consider avoiding type-checking altogether, using the interface directly.

Bootstrap 2 CSS solution:

.collapse {  transition: height 0.01s; }  

NB: setting transition: none disables the collapse functionnality.

Bootstrap 4 solution:

.collapsing {
  transition: none !important;
}

Step 1: Inject the $locationProvider service into the app config's constructor

Step 2: Add code line $locationProvider.html5Mode(true) to the app config's constructor.

Step 3: in the container (landing, master, or layout) page, add html tag such as <base href="/"> inside the tag.

Step 4: remove all '#" for routing config from all anchor tags. For examples, href="#home" becomes href="home"; href="#about" becomes herf="about"; href="#contact" becomes href="contact"

 <ul class="nav navbar-nav">
     <li><a href="home">Home</a></li>
     <li><a href="about">About us</a></li>
     <li><a href="contact">Contact us</a></li>
</ul>

In case of a large file you can use pandas.read_csv with the chunksize argument which allows to read the dataset per chunk:

import pandas as pd

INPUT_CSV = "input.csv"
OUTPUT_CSV = "output.csv"
CHUNKSIZE = 1_000 # Maximum number of rows in memory

header = True
mode = "w"
for chunk_df in pd.read_csv(INPUT_CSV, chunksize=CHUNKSIZE):
    chunk_df["Berry"] = chunk_df["Name"]
    # You apply any other transformation to the chunk
    # ...
    chunk_df.to_csv(OUTPUT_CSV, header=header, mode=mode)
    header = False # Do not save the header for the other chunks
    mode = "a" # 'a' stands for append mode, all the other chunks will be appended

If you want to update the file inplace, you can use a temporary file and erase it at the end

import pandas as pd

INPUT_CSV = "input.csv"
TMP_CSV = "tmp.csv"
CHUNKSIZE = 1_000 # Maximum number of rows in memory

header = True
mode = "w"
for chunk_df in pd.read_csv(INPUT_CSV, chunksize=CHUNKSIZE):
    chunk_df["Berry"] = chunk_df["Name"]
    # You apply any other transformation to the chunk
    # ...
    chunk_df.to_csv(TMP_CSV, header=header, mode=mode)
    header = False # Do not save the header for the other chunks
    mode = "a" # 'a' stands for append mode, all the other chunks will be appended

os.replace(TMP_CSV, INPUT_CSV)

Sample DF:

In [79]: df = pd.DataFrame(np.random.randint(5, 15, (10, 3)), columns=list('abc'))

In [80]: df
Out[80]:
    a   b   c
0   6  11  11
1  14   7   8
2  13   5  11
3  13   7  11
4  13   5   9
5   5  11   9
6   9   8   6
7   5  11  10
8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

I needed to import javaee-api as well.

  <dependency>
     <groupId>javax</groupId>
     <artifactId>javaee-api</artifactId>
     <version>7.0</version>
  </dependency>

Unless I got following error:

package javax.servlet.http does not exist
javax.servlet.annotation does not exist
javax.servlet.http does not exist
...

If your items in the array are not primitive you can use spread operator to do that.

this.plansCopy = this.plans.map(obj => ({...obj}));

For java, you also need to learn how to use an IDE and setup your environment and this kind of this to make java works...

Then for J2ME, you'll need to know things about embedded/mobile systems....

10 weeks with the tutorials would be ok but it also depends on what you're going to do in your j2me course...

I would go head first in a j2me tutorial (assuming you know a minimum concerning variables functions and OO)...

good luck...

In my case, I had a OneToOne relation which I was using with @Column by mistake. I changed it to @JoinColumn and added @OneToOne annotation and it fixed the exception.

Try this

\d{1,2}\.?(\.\d{1,2})?

mkdirs() will create the specified directory path in its entirety where mkdir() will only create the bottom most directory, failing if it can't find the parent directory of the directory it is trying to create.

In other words mkdir() is like mkdir and mkdirs() is like mkdir -p.

For example, imagine we have an empty /tmp directory. The following code

new File("/tmp/one/two/three").mkdirs();

would create the following directories:

• /tmp/one
• /tmp/one/two
• /tmp/one/two/three

Where this code:

new File("/tmp/one/two/three").mkdir();

would not create any directories - as it wouldn't find /tmp/one/two - and would return false.

Like that we can do....

int main(int argc, char *argv[]) {

    int a, b, c;
    *// Converting string type to integer type
    // using function "atoi( argument)"* 

    a = atoi(argv[1]);     
    b = atoi(argv[2]);
    c = atoi(argv[3]);

 }

Canvases are transparent by default.

Try setting a page background image, and then put a canvas over it. If nothing is drawn on the canvas, you can fully see the page background.

Think of a canvas as like painting on a glass plate.

The standard library includes the ordered and the unordered map (std::map and std::unordered_map) containers. In an ordered map the elements are sorted by the key, insert and access is in O(log n). Usually the standard library internally uses red black trees for ordered maps. But this is just an implementation detail. In an unordered map insert and access is in O(1). It is just another name for a hashtable.

An example with (ordered) std::map:

#include <map>
#include <iostream>
#include <cassert>

int main(int argc, char **argv)
{
  std::map<std::string, int> m;
  m["hello"] = 23;
  // check if key is present
  if (m.find("world") != m.end())
    std::cout << "map contains key world!\n";
  // retrieve
  std::cout << m["hello"] << '\n';
  std::map<std::string, int>::iterator i = m.find("hello");
  assert(i != m.end());
  std::cout << "Key: " << i->first << " Value: " << i->second << '\n';
  return 0;
}

Output:

23
Key: hello Value: 23

If you need ordering in your container and are fine with the O(log n) runtime then just use std::map.

Otherwise, if you really need a hash-table (O(1) insert/access), check out std::unordered_map, which has a similar to std::map API (e.g. in the above example you just have to search and replace map with unordered_map).

The unordered_map container was introduced with the C++11 standard revision. Thus, depending on your compiler, you have to enable C++11 features (e.g. when using GCC 4.8 you have to add -std=c++11 to the CXXFLAGS).

Even before the C++11 release GCC supported unordered_map - in the namespace std::tr1. Thus, for old GCC compilers you can try to use it like this:

#include <tr1/unordered_map>

std::tr1::unordered_map<std::string, int> m;

It is also part of boost, i.e. you can use the corresponding boost-header for better portability.

val() should handle both cases

  <option value="1">it's me</option>      


$('select').val('1'); // selects "it's me"

$('select').val("it's me"); // also selects "it's me"

The selected answer is correct but if you prefer to do this sort of thing in Interface Builder you can do this:

You can add Apache Commons Lang in Gradle like compile 'org.apache.commons:commons-lang3:3.4'

And use WordUtils.capitalizeFully(name)

It doesn't matter - they're both allowed inside each other.

I'm not aware of a CSS-only solution.

As you mentioned, filters are the canonical approach to creating drop shadow effects in SVG. The SVG specification includes an example of this.

you can also use

word-break: break-all;

when nothing seems working this works always ;)

my rule of thumb is:

rebase for branches with the same name, merge otherwise.

examples for same names would be master, origin/master and otherRemote/master.

if develop exists only in the local repository, and it is always based on a recent origin/master commit, you should call it master, and work there directly. it simplifies your life, and presents things as they actually are: you are directly developing on the master branch.

if develop is shared, it should not be rebased on master, just merged back into it with --no-ff. you are developing on develop. master and develop have different names, because we want them to be different things, and stay separate. do not make them same with rebase.

You must know the source encoding.

string someText = "The quick brown fox jumps over the lazy dog.";
byte[] bytes = Encoding.Unicode.GetBytes(someText);
char[] chars = Encoding.Unicode.GetChars(bytes);

This is more advice than a specific answer, but my suggestion is to convert dates to date variables immediately, rather than keeping them as strings. This way you can use date (and time) functions on them, rather than trying to use very troublesome workarounds.

As pointed out, the lubridate package has nice extraction functions.

For some projects, I have found that piecing dates out from the start is helpful: create year, month, day (of month) and day (of week) variables to start with. This can simplify summaries, tables and graphs, because the extraction code is separate from the summary/table/graph code, and because if you need to change it, you don't have to roll out those changes in multiple spots.

If you run npm config edit, you'll get an editor showing the current configuration, and also a list of options and their default values.

But I don't think there's a 'reset' command.

Let's say you would like to pass the string Dev as a parameter, from your batch file:

powershell -command "G:\Karan\PowerShell_Scripts\START_DEV.ps1 Dev"

put inside your powershell script head:

$w = $args[0]       # $w would be set to "Dev"

This if you want to use the built-in variable $args. Otherwise:

 powershell -command "G:\Karan\PowerShell_Scripts\START_DEV.ps1 -Environment \"Dev\""

and inside your powershell script head:

param([string]$Environment)

This if you want a named parameter.

You might also be interested in returning the error level:

powershell -command "G:\Karan\PowerShell_Scripts\START_DEV.ps1 Dev; exit $LASTEXITCODE"

The error level will be available inside the batch file as %errorlevel%.
