Beginning with C# 8.0, an interface member may declare a body. This is called a default implementation. Members with bodies permit the interface to provide a "default" implementation for classes and structs that don't provide an overriding implementation. In addition, beginning with C# 8.0, an interface may include:

Constants Operators Static constructor. Nested types Static fields, methods, properties, indexers, and events Member declarations using the explicit interface implementation syntax. Explicit access modifiers (the default access is public).

1. Create the Java code that can receive an argument as a command line argument.

   class TestCode{
       public static void main(String args[]){
           System.out.println("first argument is: "+args[0]);
       }
   }
   

2. Run the program without arguments (press F6).

3. In the Output window, at the bottom, click the double yellow arrow (or the yellow button) to open a Run dialog.

4. If the argument you need to pass is testArgument, then here in this window pass the argument as application.args=testArgument.

This will give the output as follows in the same Output window:

first argument is: testArgument

For Maven, the instructions are similar, but change the exec.args property instead:

exec.args=-classpath %classpath package.ClassName PARAM1 PARAM2 PARAM3

Note: Use single quotes for string parameters that contain spaces.

select * from table where value % 2 = 1 works fine in mysql.

Here is the sample on what worked for me. I think that put method is needed in entity class to map sql columns to java class attributes.

    //simpleExample
    Query query = em.createNativeQuery(
"SELECT u.name,s.something FROM user u,  someTable s WHERE s.user_id = u.id", 
NameSomething.class);
    List list = (List<NameSomething.class>) query.getResultList();

Entity class:

    @Entity
    public class NameSomething {

        @Id
        private String name;

        private String something;

        // getters/setters



        /**
         * Generic put method to map JPA native Query to this object.
         *
         * @param column
         * @param value
         */
        public void put(Object column, Object value) {
            if (((String) column).equals("name")) {
                setName(String) value);
            } else if (((String) column).equals("something")) {
                setSomething((String) value);
            }
        }
    }

The problem you're having is that you're passing incompatible formats from a formatted java.util.Date to construct an instance of java.sql.Date, which don't behave in the same way when using valueOf() since they use different formats.

I also can see that you're aiming to persist hours and minutes, and I think that you'd better change the data type to java.sql.Timestamp, which supports hours and minutes, along with changing your database field to DATETIME or similar (depending on your database vendor).

Anyways, if you want to change from java.util.Date to java.sql.Date, I suggest to use

java.util.Date date = Calendar.getInstance().getTime();
java.sql.Date sqlDate = new java.sql.Date(date.getTime()); 
// ... more code here
prs.setDate(sqlDate);

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

I prefer an answer from Best way to print the result of a bool as 'false' or 'true' in c?, just like

printf("%s\n", "false\0true"+6*x);

• x == 0, "false\0true"+ 0" it means "false";
• x == 1, "false\0true"+ 6" it means "true";

Here's other way of getting Zscore using custom function:

In [6]: import pandas as pd; import numpy as np

In [7]: np.random.seed(0) # Fixes the random seed

In [8]: df = pd.DataFrame(np.random.randn(5,3), columns=["randomA", "randomB","randomC"])

In [9]: df # watch output of dataframe
Out[9]:
    randomA   randomB   randomC

4  0.761038  0.121675  0.443863

## Create custom function to compute Zscore 
In [10]: def z_score(df):
   ....:         df.columns = [x + "_zscore" for x in df.columns.tolist()]
   ....:         return ((df - df.mean())/df.std(ddof=0))
   ....:

## make sure you filter or select columns of interest before passing dataframe to function
In [11]: z_score(df) # compute Zscore

Just change your bind statement from what you have to => this.delta = this.delta.bind(this);

As Abhishek Bedi points out in a comment, For iOS7 forward the best way to do this is:

//from API docs: 
//- (void)showAnnotations:(NSArray *)annotations animated:(BOOL)animated NS_AVAILABLE(10_9, 7_0);
[self.mapView showAnnotations:self.mapView.annotations animated:YES];

For my personal project (prior to iOS7) I simply added a category on the MKMapView class to encapsulate the "visible area" functionality for a very common operation: setting it to be able to see all the currently-loaded annotations on the MKMapView instance (this includes as many pins as you might have placed, as well as the user's location). the result was this:

.h file

#import <MapKit/MapKit.h>

@interface MKMapView (Extensions)

-(void)ij_setVisibleRectToFitAllLoadedAnnotationsAnimated:(BOOL)animated;
-(void)ij_setVisibleRectToFitAnnotations:(NSArray *)annotations animated:(BOOL)animated;


@end

.m file

#import "MKMapView+Extensions.h"

@implementation MKMapView (Extensions)

/**
 *  Changes the currently visible portion of the map to a region that best fits all the currently loadded annotations on the map, and it optionally animates the change.
 *
 *  @param animated is the change should be perfomed with an animation.
 */
-(void)ij_setVisibleRectToFitAllLoadedAnnotationsAnimated:(BOOL)animated
{
    MKMapView * mapView = self;

    NSArray * annotations = mapView.annotations;

    [self ij_setVisibleRectToFitAnnotations:annotations animated:animated];

}


/**
 *  Changes the currently visible portion of the map to a region that best fits the provided annotations array, and it optionally animates the change.
    All elements from the array must conform to the <MKAnnotation> protocol in order to fetch the coordinates to compute the visible region of the map.
 *
 *  @param annotations an array of elements conforming to the <MKAnnotation> protocol, holding the locations for which the visible portion of the map will be set.
 *  @param animated    wether or not the change should be perfomed with an animation.
 */
-(void)ij_setVisibleRectToFitAnnotations:(NSArray *)annotations animated:(BOOL)animated
{
    MKMapView * mapView = self;

    MKMapRect r = MKMapRectNull;
    for (id<MKAnnotation> a in annotations) {
        ZAssert([a conformsToProtocol:@protocol(MKAnnotation)], @"ERROR: All elements of the array MUST conform to the MKAnnotation protocol. Element (%@) did not fulfill this requirement", a);
        MKMapPoint p = MKMapPointForCoordinate(a.coordinate);
        //MKMapRectUnion performs the union between 2 rects, returning a bigger rect containing both (or just one if the other is null). here we do it for rects without a size (points)
        r = MKMapRectUnion(r, MKMapRectMake(p.x, p.y, 0, 0));
    }

    [mapView setVisibleMapRect:r animated:animated];

}

@end

As you can see, I've added 2 methods so far: one for setting the visible region of the map to the one that fits all currently-loaded annotations on the MKMapView instance, and another method to set it to any array of objects. So to set the mapView's visible region the code would then be as simple as:

   //the mapView instance  
    [self.mapView ij_setVisibleRectToFitAllLoadedAnnotationsAnimated:animated]; 

I hope it helps =)

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

Very short answer :

Different databases have different uses. I'm not a database expert. Rule of thumb:

• if you are doing analytics (ex. aggregating historical data) use OLAP
• if you are doing transactions (ex. adding/removing orders on an e-commerce cart) use OLTP

Short answer:

Let's consider two example scenarios:

Scenario 1:

You are building an online store/website, and you want to be able to:

• store user data, passwords, previous transactions...
• store actual products, their associated prices

You want to be able to find data for a particular user, change its name... basically perform INSERT, UPDATE, DELETE operations on user data. Same with products, etc.

You want to be able to make transactions, possibly involving a user buying a product (that's a relation). Then OLTP is probably a good fit.

Scenario 2:

You have an online store/website, and you want to compute things like

• the "total money spent by all users"
• "what is the most sold product"

This falls into the analytics/business intelligence domain, and therefore OLAP is probably more suited.

If you think in terms of "It would be nice to know how/what/how much"..., and that involves all "objects" of one or more kind (ex. all the users and most of the products to know the total spent) then OLAP is probably better suited.

Longer answer:

Of course things are not so simple. That's why we have to use short tags like OLTPand OLAP in the first place. Each database should be evaluated independently in the end.

So what could be the fundamental difference between OLAP and OLTP?

Well, databases have to store data somewhere. It shouldn't be surprising that the way the data is stored heavily reflects the possible use of said data. Data is usually stored on a hard drive. Let's think of a hard drive as a really wide sheet of paper, where we can read and write things. There are two ways to organize our reads and writes so that they can be efficient and fast.

One way is to make a book that is a bit like a phone book. On each page of the book, we store the information regarding a particular user. Now that's nice, we can find the information for a particular user very easily! Just jump to the page! We can even have a special page at the beginning to tell us on which page the users are if we want. But on the other hand, if we want to find, say, how much money all of our users spent then we would have to read every page, i.e. the whole book! That would be a row-based book/database (OLTP). The optional page at the beginning would be the index.

Another way to use our big sheet of paper is to make an accounting book. I'm no accountant, but let's imagine that we would have a page for "expenditures", "purchases"... That's nice because now we can query things like "give me the total revenue" very quickly (just read the "purchases" page). We can also ask for more involved things like "give me the top ten products sold" and still have acceptable performance. But now consider how painful it would be to find the expenditures for a particular user. You would have to go through the whole list of everyone's expenditures and filter the ones of that particular user, then sum them. Which basically amounts to "read the whole book" again. That would be a column-based database (OLAP).

It follows that:

• OLTP databases are meant to be used to do many small transactions, and usually serve as a "single source of truth".

• OLAP databases on the other hand are more suited for analytics, data mining, fewer queries but they are usually bigger (they operate on more data).

It's a bit more involved than that of course and that's a 20 000 feet overview of how databases differ, but it allows me not to get lost in a sea of acronyms.

Speaking of acronyms:

• OLTP = Online transaction processing
• OLAP = Online analytical processing

To read a bit further, here are some relevant links which heavily inspired my answer:

• http://datawarehouse4u.info/OLTP-vs-OLAP.html
• http://www.ibmsystemsmag.com/Blogs/You-and-i/Archive/db-102-database-orientation-row-vs-column/

You need to make sure all of your assemblies are compiling for the correct architecture. Try changing the architecture for x86 if reinstalling the COM component doesn't work.

Try this:

pip install tensorflow==1.14

or this (if you have GPU):

pip install tensorflow-gpu==1.14

In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime() gives you the mentioned milliseconds).
In your solution:

Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();

long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);

you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.

Another possible solution would be to utilise the static fields of the Calendar class:

//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);

Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.

You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.

When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.

Reference:
C++03 standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:

• To move the definition to the .h file
• Add explicit instantiations in the .cpp file.
• #include the .cpp file defining the template at the .cpp file using the template.

Each of them have their pros and cons,

Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.

Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.

While including cpp files is confusing at the same time shares the problems of both above approaches.

I find first method the easiest to follow and implement and hence advocte using it.

To send a file from windows to linux system

scp path-to-file user@ipaddress:/path-to-destination

Example:

scp C:/Users/adarsh/Desktop/Document.txt [email protected]:/tmp

keep in mind that there need to use forward slash(/) inplace of backward slash(\) in for the file in windows path else it will show an error

C:UsersadarshDesktopDocument.txt: No such file or directory

. After executing scp command you will ask for password of root user in linux machine. There you GO...

To send a file from linux to windows system

scp -r user@ipaddress:/path-to-file path-to-destination

Example:

scp -r [email protected]:/tmp/Document.txt C:/Users/adarsh/Desktop/

and provide your linux password. only one you have to add in this command is -r. Thanks.

I found that by shutting down a Console and a running Simulator allowed XCode to see my iPhone again. I'd make sure other related programs aren't running if you don't need them.

Among several options for shading and tinting:

• For shades, multiply each component by 1/4, 1/2, 3/4, etc., of its previous value. The smaller the factor, the darker the shade.

• For tints, calculate (255 - previous value), multiply that by 1/4, 1/2, 3/4, etc. (the greater the factor, the lighter the tint), and add that to the previous value (assuming each.component is a 8-bit integer).

Note that color manipulations (such as tints and other shading) should be done in linear RGB. However, RGB colors specified in documents or encoded in images and video are not likely to be in linear RGB, in which case a so-called inverse transfer function needs to be applied to each of the RGB color's components. This function varies with the RGB color space. For example, in the sRGB color space (which can be assumed if the RGB color space is unknown), this function is roughly equivalent to raising each sRGB color component (ranging from 0 through 1) to a power of 2.2. (Note that "linear RGB" is not an RGB color space.)

See also Violet Giraffe's comment about "gamma correction".

Probably it was some sort of my mistake because of me messing with autolayouts and storyboard but I found an answer.

You have to take care of this little guy in View Controller's Attribute Inspector

It must be unchecked so the default contentInset wouldn't be set after any change. After that it is just adding one-liner to viewDidLoad:

[self.tableView setContentInset:UIEdgeInsetsMake(108, 0, 0, 0)]; // 108 is only example

iOS 11, Xcode 9 update

Looks like the previous solution is no longer a correct one if it comes to iOS 11 and Xcode 9. automaticallyAdjustsScrollViewInsets has been deprecated and right now to achieve similar effect you have to go to Size Inspector where you can find this:
Also, you can achieve the same in code:

if #available(iOS 11.0, *) {
    scrollView.contentInsetAdjustmentBehavior = .never
} else {
    automaticallyAdjustsScrollViewInsets = false
}

Updating since these answers are slightly outdated (although some still apply).

Simple feature added in rails 2.3.4, db/seeds.rb

Provides a new rake task

rake db:seed

Good for populating common static records like states, countries, etc...

http://railscasts.com/episodes/179-seed-data

*Note that you can use fixtures if you had already created them to also populate with the db:seed task by putting the following in your seeds.rb file (from the railscast episode):

require 'active_record/fixtures'
Fixtures.create_fixtures("#{Rails.root}/test/fixtures", "operating_systems")

For Rails 3.x use 'ActiveRecord::Fixtures' instead of 'Fixtures' constant

require 'active_record/fixtures'
ActiveRecord::Fixtures.create_fixtures("#{Rails.root}/test/fixtures", "fixtures_file_name")

I guess, a column value in a foreign key table should match with the column value of the primary key table. If we are trying to create a foreign key constraint between two tables where the value inside one column(going to be the foreign key) is different from the column value of the primary key table then it will throw the message.

So it is always recommended to insert only those values in the Foreign key column which are present in the Primary key table column.

For ex. If the Primary table column has values 1, 2, 3 and in Foreign key column the values inserted are different, then the query would not be executed as it expects the values to be between 1 & 3.

Update for .NET Framework 4.5 and 4.6; the following will no longer work:

string keyvalue = System.Configuration.ConfigurationManager.AppSettings["keyname"];

Now access the Setting class via Properties:

string keyvalue = Properties.Settings.Default.keyname;

See Managing Application Settings for more information.

Just use os.path.dirname(os.path.abspath(__file__)) and examine very carefully whether there is a real need for the case where exec is used. It could be a sign of troubled design if you are not able to use your script as a module.

Keep in mind Zen of Python #8, and if you believe there is a good argument for a use-case where it must work for exec, then please let us know some more details about the background of the problem.

Sooo simple to get row count:

cursor = dbObj.rawQuery("select count(*) from TABLE where COLUMN_NAME = '1' ", null);
cursor.moveToFirst();
String count = cursor.getString(cursor.getColumnIndex(cursor.getColumnName(0)));

Actually if you downloaded the icons pack from the android web site, you will see that you have one folder per resolution named drawable-mdpi etc. Copy all folders into the res (not the drawable) folder in Android Studio. This will automatically make all the different resolution of the icon available.

Perhaps you're trying to modularize your package. I'm assuming that package1 and package2 are, in a way, part of the same package but for readability you're splitting those into multiple files.

If the previous case was yours, you could use the same package name into those multiples files and it will be like if there were the same file.

This is an example:

add.go

package math

func add(n1, n2 int) int {
   return n1 + n2
}

subtract.go

package math

func subtract(n1, n2 int) int {
    return n1 - n2
}

donothing.go

package math

func donothing(n1, n2 int) int {
    s := add(n1, n2)
    s = subtract(n1, n2)
    return s
}

I am not a Go expert and this is my first post in StackOveflow, so if you have some advice it will be well received.

I have written a simple dns proxy in Python. It will read wildcard entries in /etc/hosts. See here: http://code.google.com/p/marlon-tools/source/browse/tools/dnsproxy/dnsproxy.py

I have tested in Linux & Mac OS X, but not yet in Windows.

While other answers provide detailed solutions for various setups, this might help someone who is just looking for a general answer.

There are three general options, pick one or more:

1. On the client side, delete the cookie from the browser using javascript.

2. On the server side, set the cookie value to an empty string or something useless (for example "deleted"), and set the cookie expiration time to a time in the past.

3. On the server side, update the refreshtoken stored in your database. Use this option to log out the user from all devices where they are logged in (their refreshtokens will become invalid and they have to log in again).

It is possible to use filter predicates to specify which rows to include in the index.

From the documentation:

WHERE <filter_predicate> Creates a filtered index by specifying which rows to include in the index. The filtered index must be a nonclustered index on a table. Creates filtered statistics for the data rows in the filtered index.

Example:

CREATE TABLE Table1 (
  NullableCol int NULL
)

CREATE UNIQUE INDEX IX_Table1 ON Table1 (NullableCol) WHERE NullableCol IS NOT NULL;

You can also use file_put_contents():

file_put_contents('ids.txt', implode("\n", $gemList) . "\n", FILE_APPEND);

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.

you can consider something like that:

1. define a style for textblock, or any other control you want to use to display your enum:

   <Style x:Key="enumStyle" TargetType="{x:Type TextBlock}">
       <Setter Property="Text" Value="&lt;NULL&gt;"/>
       <Style.Triggers>
           <Trigger Property="Tag">
               <Trigger.Value>
                   <proj:YourEnum>Value1<proj:YourEnum>
               </Trigger.Value>
               <Setter Property="Text" Value="{DynamicResource yourFriendlyValue1}"/>
           </Trigger>
           <!-- add more triggers here to reflect your enum -->
       </Style.Triggers>
   </Style>
   

2. define your style for ComboBoxItem

   <Style TargetType="{x:Type ComboBoxItem}">
       <Setter Property="ContentTemplate">
           <Setter.Value>
               <DataTemplate>
                   <TextBlock Tag="{Binding}" Style="{StaticResource enumStyle}"/>
               </DataTemplate>
           </Setter.Value>
       </Setter>
   </Style>
   

3. add a combobox and load it with your enum values:

   <ComboBox SelectedValue="{Binding Path=your property goes here}" SelectedValuePath="Content">
       <ComboBox.Items>
           <ComboBoxItem>
               <proj:YourEnum>Value1</proj:YourEnum>

if your enum is large, you can of course do the same in code, sparing a lot of typing. i like that approach, since it makes localization easy - you define all the templates once, and then, you only update your string resource files.

For anyone where none of these solutions are working, make sure that your request origin equals your request target, see this github issue.

I short, if you visit your website on 127.0.0.1:8000, then make sure that the requests you send are targeting your server on 127.0.0.1:8001 and not localhost:8001, although it might be the same target theoretically.

static byte[] SliceMe(byte[] source, int length)
{
    byte[] destfoo = new byte[length];
    Array.Copy(source, 0, destfoo, 0, length);
    return destfoo;
}

//

var myslice = SliceMe(sourcearray,41);

When your activity is recreated after it was previously destroyed, you can recover your saved state from the Bundle that the system passes your activity. Both the onCreate() and onRestoreInstanceState() callback methods receive the same Bundle that contains the instance state information.

Because the onCreate() method is called whether the system is creating a new instance of your activity or recreating a previous one, you must check whether the state Bundle is null before you attempt to read it. If it is null, then the system is creating a new instance of the activity, instead of restoring a previous one that was destroyed.

static final String STATE_USER = "user";
private String mUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Check whether we're recreating a previously destroyed instance
    if (savedInstanceState != null) {
        // Restore value of members from saved state
        mUser = savedInstanceState.getString(STATE_USER);
    } else {
        // Probably initialize members with default values for a new instance
        mUser = "NewUser";
    }
}

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString(STATE_USER, mUser);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

http://developer.android.com/training/basics/activity-lifecycle/recreating.html

In your app.js file:

.run(["$rootScope", "$state", function($rootScope, $state) {

      $rootScope.$on('$locationChangeStart', function(event, next, current) {
        if (!$rootScope.loggedUser == null) {
          $state.go('home');
        }    
      });
}])

Recommended for short lists only:

any(thelist.count(x) > 1 for x in thelist)

Do not use on a long list -- it can take time proportional to the square of the number of items in the list!

For longer lists with hashable items (strings, numbers, &c):

def anydup(thelist):
  seen = set()
  for x in thelist:
    if x in seen: return True
    seen.add(x)
  return False

If your items are not hashable (sublists, dicts, etc) it gets hairier, though it may still be possible to get O(N logN) if they're at least comparable. But you need to know or test the characteristics of the items (hashable or not, comparable or not) to get the best performance you can -- O(N) for hashables, O(N log N) for non-hashable comparables, otherwise it's down to O(N squared) and there's nothing one can do about it:-(.

FXCop typically prefers OrdinalIgnoreCase. But your requirements may vary.

For English there is very little difference. It is when you wander into languages that have different written language constructs that this becomes an issue. I am not experienced enough to give you more than that.

OrdinalIgnoreCase

The StringComparer returned by the OrdinalIgnoreCase property treats the characters in the strings to compare as if they were converted to uppercase using the conventions of the invariant culture, and then performs a simple byte comparison that is independent of language. This is most appropriate when comparing strings that are generated programmatically or when comparing case-insensitive resources such as paths and filenames. http://msdn.microsoft.com/en-us/library/system.stringcomparer.ordinalignorecase.aspx

InvariantCultureIgnoreCase

The StringComparer returned by the InvariantCultureIgnoreCase property compares strings in a linguistically relevant manner that ignores case, but it is not suitable for display in any particular culture. Its major application is to order strings in a way that will be identical across cultures. http://msdn.microsoft.com/en-us/library/system.stringcomparer.invariantcultureignorecase.aspx

The invariant culture is the CultureInfo object returned by the InvariantCulture property.

The InvariantCultureIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.

In my case, none of the code above with bundle-operate works; Here is my decision (I don't know if it is proper code or not, but it works in my case):

public class DialogMessageType extends DialogFragment {
    private static String bodyText;

    public static DialogMessageType addSomeString(String temp){
        DialogMessageType f = new DialogMessageType();
        bodyText = temp;
        return f;
    };

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        final String[] choiseArray = {"sms", "email"};
        String title = "Send text via:";
        final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle(title).setItems(choiseArray, itemClickListener);
        builder.setCancelable(true);
        return builder.create();
    }

    DialogInterface.OnClickListener itemClickListener = new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            switch (which){
                case 0:
                    prepareToSendCoordsViaSMS(bodyText);
                    dialog.dismiss();
                    break;
                case 1:
                    prepareToSendCoordsViaEmail(bodyText);
                    dialog.dismiss();
                    break;
                default:
                    break;
            }
        }
    };
[...]
}

public class SendObjectActivity extends FragmentActivity {
[...]

DialogMessageType dialogMessageType = DialogMessageType.addSomeString(stringToSend);
dialogMessageType.show(getSupportFragmentManager(),"dialogMessageType");

[...]
}

As Adrian said, the plugins are going to work the same way. There are three basic parts you're going to need:

1: Event handler for 'contextmenu' event:

$(document).bind("contextmenu", function(event) {
    event.preventDefault();
    $("<div class='custom-menu'>Custom menu</div>")
        .appendTo("body")
        .css({top: event.pageY + "px", left: event.pageX + "px"});
});

Here, you could bind the event handler to any selector that you want to show a menu for. I've chosen the entire document.

2: Event handler for 'click' event (to close the custom menu):

$(document).bind("click", function(event) {
    $("div.custom-menu").hide();
});

3: CSS to control the position of the menu:

.custom-menu {
    z-index:1000;
    position: absolute;
    background-color:#C0C0C0;
    border: 1px solid black;
    padding: 2px;
}

The important thing with the CSS is to include the z-index and position: absolute

It wouldn't be too tough to wrap all of this in a slick jQuery plugin.

You can see a simple demo here: http://jsfiddle.net/andrewwhitaker/fELma/

Try this

ImageView img
    Bitmap bmp;
    int width=100;
    int height=100;
    img=(ImageView)findViewById(R.id.imgView);
    bmp=BitmapFactory.decodeResource(getResources(),R.drawable.image);//image is your image                                                            
    bmp=Bitmap.createScaledBitmap(bmp, width,height, true);
    img.setImageBitmap(bmp);

Or If you want to load complete image size in memory then you can use

<ImageView
    android:id="@+id/img"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:src="@drawable/image" 
    android:scaleType="fitXY"/>

It looks like using custom fonts has been made easy with Android O, you can basically use xml to achieve this. I have attached a link to Android official documentation for reference, and hopefully this will help people who still need this solution. Working with custom fonts in Android

I had the same issue. And in my case the fix was pretty simple. The trick is to simply add the ".exe" to your compilers path. So, instead of :

SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc)

It should be

SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc.exe)

The same applies for g++.

As an addendum to this, I've strings of the form: Some words 303

where I'd like to split off the numerical part from the tail of the string. This seems to point to a possible solution:

http://lists.mysql.com/mysql/222421

The problem however, is that you only get the answer "yes, it matches", and not the start index of the regexp match.

Using the documented jquery .data(obj) syntax allows you to store an object on the DOM element. Inspecting the element will not show the data- attribute because there is no key specified for the value of the object. However, data within the object can be referenced by key with .data("foo") or the entire object can be returned with .data().

So assuming you set up a loop and result[i] = { name: "image_name" } :

$('.delete')[i].data(results[i]); // => <button class="delete">Delete</delete>
$('.delete')[i].data('name'); // => "image_name"
$('.delete')[i].data(); // => { name: "image_name" }

The "error_page" parameter makes a redirect, converting the request method to "GET", it is not a custom response page.

The easiest solution is

     server{
         root /var/www/html;
         location ~ \.php {
            if (!-f $document_root/$fastcgi_script_name){
                return 404;
            }
            fastcgi_pass   127.0.0.1:9000;
            include fastcgi_params.default;
            fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
        }

By the way, if you want Nginx to process 404 status returned by PHP scripts, you need to add

[fastcgi_intercept_errors][1] on;

E.g.

     location ~ \.php {
            #...
            error_page  404   404.html;
            fastcgi_intercept_errors on;
         }

I agree with dfsq if all you want to do is show the button. If you want to switch between hiding and showing the button however, it is easier to use:

$("#buttonEditComment").toggleClass("hide");

Old question but appears to have a lot of traffic, here is a simple solution:

IntPtr GetMainWindowHandle(IntPtr aHandle) {
        return System.Diagnostics.Process.GetProcessById(aHandle.ToInt32()).MainWindowHandle;
}

The following example is based on jQuery but it can be achieved using any JS tool kit or even plain old JS

$(document).ready(function(){
     $("#a").mouseover(function(){
         $("#b").css("background-color", "red");
     });
});

The value of the accept attribute is, as per HTML5 LC, a comma-separated list of items, each of which is a specific media type like image/gif, or a notation like image/* that refers to all image types, or a filename extension like .gif. IE 10+ and Chrome support all of these, whereas Firefox does not support the extensions. Thus, the safest way is to use media types and notations like image/*, in this case

<input type="file" name="foo" accept=
"application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint,
text/plain, application/pdf, image/*">

if I understand the intents correctly. Beware that browsers might not recognize the media type names exactly as specified in the authoritative registry, so some testing is needed.

Whenever you insert an image it just takes the width that the image has originally. You can add any other html element next to it and you will see that it will allow it. That makes image an "inline" element.

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

I was able to use Joey's Answer to create a function:

Use it as:

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION

SET "MYTEXT=jump over the chair"
echo !MYTEXT!
call:ReplaceText "!MYTEXT!" chair table RESULT
echo !RESULT!

GOTO:EOF

And these Functions to the bottom of your Batch File.

@REM FUNCTIONS AREA
GOTO:EOF
EXIT /B

:ReplaceText
::Replace Text In String
::USE:
:: CALL:ReplaceText "!OrginalText!" OldWordToReplace NewWordToUse  Result
::Example
::SET "MYTEXT=jump over the chair"
::  echo !MYTEXT!
::  call:ReplaceText "!MYTEXT!" chair table RESULT
::  echo !RESULT!
::
:: Remember to use the "! on the input text, but NOT on the Output text.
:: The Following is Wrong: "!MYTEXT!" !chair! !table! !RESULT!
:: ^^Because it has a ! around the chair table and RESULT
:: Remember to add quotes "" around the MYTEXT Variable when calling.
:: If you don't add quotes, it won't treat it as a single string
::
set "OrginalText=%~1"
set "OldWord=%~2"
set "NewWord=%~3"
call set OrginalText=%%OrginalText:!OldWord!=!NewWord!%%
SET %4=!OrginalText!
GOTO:EOF

And remember you MUST add "SETLOCAL ENABLEDELAYEDEXPANSION" to the top of your batch file or else none of this will work properly.

SETLOCAL ENABLEDELAYEDEXPANSION
@REM # Remember to add this to the top of your batch file.

You could use String.prototype.indexOf to accomplish that. Try something like this:

$('.type').keyup(function() {_x000D_
  var v = $(this).val();_x000D_
  if (v.indexOf('> <') !== -1) {_x000D_
    console.log('contains > <');_x000D_
  }_x000D_
  console.log(v);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<textarea class="type"></textarea>

Update

Modern browsers also have a String.prototype.includes method.

For starters, you can "disable" the option from being selected accidentally by users:

<option value="" disabled="disabled">Choose an option</option>

Then, inside your JavaScript event (doesn't matter whether it is jQuery or JavaScript), for your form to validate whether it is set, do:

select = document.getElementById('select'); // or in jQuery use: select = this;
if (select.value) {
  // value is set to a valid option, so submit form
  return true;
}
return false;

Or something to that effect.

I am using Windows 10 and notepad++, and I was getting this error message:

git config --global core.editor 'C:/Program\ Files\ \(x86\)/Notepad++/notepad++.exe'

and it works

For sql server (SSMS)

select MAX(LEN(ColumnName)) from table_name

This will returns number of characters.

 select MAX(DATALENGTH(ColumnName)) from table_name

This will returns number of bytes used/required.

IF some one use varchar then use DATALENGTH.More details

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

I like simple.

• The Fred activity has two modes -- HAPPY and SAD.
• Create a static IntentFactory that creates your Intent for you. Pass it the Mode you want.
• The IntentFactory uses the name of the Mode class as the name of the extra.
• The IntentFactory converts the Mode to a String using name()
• Upon entry into onCreate use this info to convert back to a Mode.

• You could use ordinal() and Mode.values() as well. I like strings because I can see them in the debugger.

  public class Fred extends Activity {
  
      public static enum Mode {
          HAPPY,
          SAD,
          ;
      }
  
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.betting);
          Intent intent = getIntent();
          Mode mode = Mode.valueOf(getIntent().getStringExtra(Mode.class.getName()));
          Toast.makeText(this, "mode="+mode.toString(), Toast.LENGTH_LONG).show();
      }
  
      public static Intent IntentFactory(Context context, Mode mode){
          Intent intent = new Intent();
          intent.setClass(context,Fred.class);
          intent.putExtra(Mode.class.getName(),mode.name());
  
          return intent;
      }
  }
  

Try This

if (($val >= 1 && $val <= 10) || ($val >= 20 && $val <= 40))

This will return the value between 1 to 10 & 20 to 40.

If you want the types of convenience methods mentioned in other answers but need portability (or even if you don't), you might want to check out Flurl [disclosure: I'm the author]. It (thinly) wraps HttpClient and Json.NET and adds some fluent sugar and other goodies, including some baked-in testing helpers.

Post as JSON:

var resp = await "http://localhost:44268/api/test".PostJsonAsync(widget);

or URL-encoded:

var resp = await "http://localhost:44268/api/test".PostUrlEncodedAsync(widget);

Both examples above return an HttpResponseMessage, but Flurl includes extension methods for returning other things if you just want to cut to the chase:

T poco = await url.PostJsonAsync(data).ReceiveJson<T>();
dynamic d = await url.PostUrlEncodedAsync(data).ReceiveJson();
string s = await url.PostUrlEncodedAsync(data).ReceiveString();

Flurl is available on NuGet:

System.out.println(path);

System.out.println(Files.readString(path));

Note: Leading . is not needed.

var optionTexts = [];
$("ul li").each(function() { optionTexts.push($(this).text()) });

...should do the trick. To get the final output you're looking for, join() plus some concatenation will do nicely:

var quotedCSV = '"' + optionTexts.join('", "') + '"';

That's because your dat1 and dat2 variables are just strings.

You should parse them to get a Date object, for that format I always use the following function:

// parse a date in yyyy-mm-dd format
function parseDate(input) {
  var parts = input.match(/(\d+)/g);
  // new Date(year, month [, date [, hours[, minutes[, seconds[, ms]]]]])
  return new Date(parts[0], parts[1]-1, parts[2]); // months are 0-based
}

I use this function because the Date.parse(string) (or new Date(string)) method is implementation dependent, and the yyyy-MM-dd format will work on modern browser but not on IE, so I prefer doing it manually.

Set sh1 = Worksheets(filenum(lngPosition)).Activate

You are getting Subscript out of range error error becuase it cannot find that Worksheet.

Also please... please... please do not use .Select/.Activate/Selection/ActiveCell You might want to see How to Avoid using Select in Excel VBA Macros.

The easiest and the cleanest way IMHO is :

q.data$number.of.a <- lengths(gregexpr('a', q.data$string))

#  number     string number.of.a`
#1      1 greatgreat           2`
#2      2      magic           1`
#3      3        not           0`

1. Include a dependency on spring-boot-configuration-processor
2. Click "Reimport All Maven Projects" in the Maven pane of IDEA
3. Rebuild project

select convert(varchar(10), cast(fmdate as date), 101) from sery

Without cast I was not getting fmdate converted, so fmdate was a string.

You can use pytz as well..

import datetime
import pytz
def utcnow():
    return datetime.datetime.now(tz=pytz.utc)
utcnow()
   datetime.datetime(2020, 8, 15, 14, 45, 19, 182703, tzinfo=<UTC>)
utcnow().isoformat()

'

That's the job that GNU's automake/autoconf are designed to solve. You might want to investigate them.

Alternatively you can set environment variables on your different platforms and make you Makefile conditional against them.

I was able to fix the problems on Windows machine by changing core.autocrlf from false to core.autocrlf=input

git config core.autocrlf input

as it's suggested in https://stackoverflow.com/a/1112313/52277

We've found a simple and decent way to do this. It's cross-browser,degradable, and doesn't break a form post. First set the select box's opacity to 0.

.select { 
    opacity : 0;
    width: 200px;
    height: 15px;
}

<select class='select'>
    <option value='foo'>bar</option>    
</select>

this is so you can still click on it

Then make div with the same dimensions as the select box. The div should lay under the select box as the background. Use { position: absolute } and z-index to achieve this.

.div {
    width: 200px;
    height: 15px;
    position: absolute;
    z-index: 0;
}

<div class='.div'>{the text of the the current selection updated by javascript}</div>
<select class='select'>
    <option value='foo'>bar</option>    
</select>

Update the div's innerHTML with javascript. Easypeasy with jQuery:

$('.select').click(function(event)) { 
    $('.div').html($('.select option:selected').val());
}

That's it! Just style your div instead of the select box. I haven't tested the above code so you'll probably need tweak it. But hopefully you get the gist.

I think this solution beats {-webkit-appearance: none;}. What browsers should do at the very most is dictate interaction with form elements, but definitely not how their initially displayed on the page as that breaks site design.

Just for giggles, give this XAML a whirl. It isn't perfect as it is not an 'alignment' but it allows you to adjust text alignment within a paragraph.

<TextBlock>
    <TextBlock BaselineOffset="30">One</TextBlock>
    <TextBlock BaselineOffset="20">Two</TextBlock>  
    <Run>Three</Run>            
    <Run BaselineAlignment="Subscript">Four</Run>   
</TextBlock>

To figure out what the linker is looking for, run it in verbose mode.

For example, I encountered this issue while trying to compile MySQL with ZLIB support. I was receiving an error like this during compilation:

/usr/bin/ld: cannot find -lzlib

I did some Googl'ing and kept coming across different issues of the same kind where people would say to make sure the .so file actually exists and if it doesn't, then create a symlink to the versioned file, for example, zlib.so.1.2.8. But, when I checked, zlib.so DID exist. So, I thought, surely that couldn't be the problem.

I came across another post on the Internets that suggested to run make with LD_DEBUG=all:

LD_DEBUG=all make

Although I got a TON of debugging output, it wasn't actually helpful. It added more confusion than anything else. So, I was about to give up.

Then, I had an epiphany. I thought to actually check the help text for the ld command:

ld --help

From that, I figured out how to run ld in verbose mode (imagine that):

ld -lzlib --verbose

This is the output I got:

==================================================
attempt to open /usr/x86_64-linux-gnu/lib64/libzlib.so failed
attempt to open /usr/x86_64-linux-gnu/lib64/libzlib.a failed

attempt to open /usr/lib/libzlib.so failed
attempt to open /usr/lib/libzlib.a failed
/usr/bin/ld.bfd.real: cannot find -lzlib

Ding, ding, ding...

So, to finally fix it so I could compile MySQL with my own version of ZLIB (rather than the bundled version):

sudo ln -s /usr/lib/libz.so.1.2.8 /usr/lib/libzlib.so

Voila!

I faced the same issue. But changing two configuration in eclipse.ini resolved my issue.

-Xms512m to -Xms1024m and -Xmx1024m to -Xmx2048m

Use calendar.monthrange:

>>> from calendar import monthrange
>>> monthrange(2011, 2)
(1, 28)

Just to be clear, monthrange supports leap years as well:

>>> from calendar import monthrange
>>> monthrange(2012, 2)
(2, 29)

As @mikhail-pyrev mentions in a comment:

First number is weekday of first day of the month, second number is number of days in said month.

This BASH script will execute the python unittest test directory from ANYWHERE in the file system, no matter what working directory you are in: its working directory always be where that test directory is located.

ALL TESTS, independent $PWD

unittest Python module is sensitive to your current directory, unless you tell it where (using discover -s option).

This is useful when staying in the ./src or ./example working directory and you need a quick overall unit test:

#!/bin/bash
this_program="$0"
dirname="`dirname $this_program`"
readlink="`readlink -e $dirname`"

python -m unittest discover -s "$readlink"/test -v

SELECTED TESTS, independent $PWD

I name this utility file: runone.py and use it like this:

runone.py <test-python-filename-minus-dot-py-fileextension>

#!/bin/bash
this_program="$0"
dirname="`dirname $this_program`"
readlink="`readlink -e $dirname`"

(cd "$dirname"/test; python -m unittest $1)

No need for a test/__init__.py file to burden your package/memory-overhead during production.

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

skip = OFFSET
$products = $art->products->skip(0)->take(10)->get(); //get first 10 rows
$products = $art->products->skip(10)->take(10)->get(); //get next 10 rows

From laravel doc 5.2 https://laravel.com/docs/5.2/queries#ordering-grouping-limit-and-offset

skip / take

To limit the number of results returned from the query, or to skip a given number of results in the query (OFFSET), you may use the skip and take methods:

$users = DB::table('users')->skip(10)->take(5)->get();

In laravel 5.3 you can write (https://laravel.com/docs/5.3/queries#ordering-grouping-limit-and-offset)

$products = $art->products->offset(0)->limit(10)->get(); 

In addition to all the regular confusion around SAP issues might also stem form the fact that SAP used to have their own DBMS ..

It used to be called Adabas (marketed originally by Nixdorf and then by Software AG) and was a quite popular DBMS for smaller SAP (the ERP solution) installations in Germany. At some point (AFAIK around 2000) SAP started to co-develop/support/take over Adabas and marketed it as SAP DB and later MaxDB under commercial and open-source licenses. There also was/is some agreement with MySQL.

But when people talk about SAP, they usually refer to the ERP solution as the other posters have noted.

You will definitely want to start with a good web scraping framework. Later on you may decide that they are too limiting and you can put together your own stack of libraries but without a lot of scraping experience your design will be much worse than pjscrape or scrapy.

Note: I use the terms crawling and scraping basically interchangeable here. This is a copy of my answer to your Quora question, it's pretty long.

Tools

Get very familiar with either Firebug or Chrome dev tools depending on your preferred browser. This will be absolutely necessary as you browse the site you are pulling data from and map out which urls contain the data you are looking for and what data formats make up the responses.

You will need a good working knowledge of HTTP as well as HTML and will probably want to find a decent piece of man in the middle proxy software. You will need to be able to inspect HTTP requests and responses and understand how the cookies and session information and query parameters are being passed around. Fiddler (http://www.telerik.com/fiddler) and Charles Proxy (http://www.charlesproxy.com/) are popular tools. I use mitmproxy (http://mitmproxy.org/) a lot as I'm more of a keyboard guy than a mouse guy.

Some kind of console/shell/REPL type environment where you can try out various pieces of code with instant feedback will be invaluable. Reverse engineering tasks like this are a lot of trial and error so you will want a workflow that makes this easy.

Language

PHP is basically out, it's not well suited for this task and the library/framework support is poor in this area. Python (Scrapy is a great starting point) and Clojure/Clojurescript (incredibly powerful and productive but a big learning curve) are great languages for this problem. Since you would rather not learn a new language and you already know Javascript I would definitely suggest sticking with JS. I have not used pjscrape but it looks quite good from a quick read of their docs. It's well suited and implements an excellent solution to the problem I describe below.

A note on Regular expressions: DO NOT USE REGULAR EXPRESSIONS TO PARSE HTML. A lot of beginners do this because they are already familiar with regexes. It's a huge mistake, use xpath or css selectors to navigate html and only use regular expressions to extract data from actual text inside an html node. This might already be obvious to you, it becomes obvious quickly if you try it but a lot of people waste a lot of time going down this road for some reason. Don't be scared of xpath or css selectors, they are WAY easier to learn than regexes and they were designed to solve this exact problem.

Javascript-heavy sites

In the old days you just had to make an http request and parse the HTML reponse. Now you will almost certainly have to deal with sites that are a mix of standard HTML HTTP request/responses and asynchronous HTTP calls made by the javascript portion of the target site. This is where your proxy software and the network tab of firebug/devtools comes in very handy. The responses to these might be html or they might be json, in rare cases they will be xml or something else.

There are two approaches to this problem:

The low level approach:

You can figure out what ajax urls the site javascript is calling and what those responses look like and make those same requests yourself. So you might pull the html from http://example.com/foobar and extract one piece of data and then have to pull the json response from http://example.com/api/baz?foo=b... to get the other piece of data. You'll need to be aware of passing the correct cookies or session parameters. It's very rare, but occasionally some required parameters for an ajax call will be the result of some crazy calculation done in the site's javascript, reverse engineering this can be annoying.

The embedded browser approach:

Why do you need to work out what data is in html and what data comes in from an ajax call? Managing all that session and cookie data? You don't have to when you browse a site, the browser and the site javascript do that. That's the whole point.

If you just load the page into a headless browser engine like phantomjs it will load the page, run the javascript and tell you when all the ajax calls have completed. You can inject your own javascript if necessary to trigger the appropriate clicks or whatever is necessary to trigger the site javascript to load the appropriate data.

You now have two options, get it to spit out the finished html and parse it or inject some javascript into the page that does your parsing and data formatting and spits the data out (probably in json format). You can freely mix these two options as well.

Which approach is best?

That depends, you will need to be familiar and comfortable with the low level approach for sure. The embedded browser approach works for anything, it will be much easier to implement and will make some of the trickiest problems in scraping disappear. It's also quite a complex piece of machinery that you will need to understand. It's not just HTTP requests and responses, it's requests, embedded browser rendering, site javascript, injected javascript, your own code and 2-way interaction with the embedded browser process.

The embedded browser is also much slower at scale because of the rendering overhead but that will almost certainly not matter unless you are scraping a lot of different domains. Your need to rate limit your requests will make the rendering time completely negligible in the case of a single domain.

Rate Limiting/Bot behaviour

You need to be very aware of this. You need to make requests to your target domains at a reasonable rate. You need to write a well behaved bot when crawling websites, and that means respecting robots.txt and not hammering the server with requests. Mistakes or negligence here is very unethical since this can be considered a denial of service attack. The acceptable rate varies depending on who you ask, 1req/s is the max that the Google crawler runs at but you are not Google and you probably aren't as welcome as Google. Keep it as slow as reasonable. I would suggest 2-5 seconds between each page request.

Identify your requests with a user agent string that identifies your bot and have a webpage for your bot explaining it's purpose. This url goes in the agent string.

You will be easy to block if the site wants to block you. A smart engineer on their end can easily identify bots and a few minutes of work on their end can cause weeks of work changing your scraping code on your end or just make it impossible. If the relationship is antagonistic then a smart engineer at the target site can completely stymie a genius engineer writing a crawler. Scraping code is inherently fragile and this is easily exploited. Something that would provoke this response is almost certainly unethical anyway, so write a well behaved bot and don't worry about this.

Testing

Not a unit/integration test person? Too bad. You will now have to become one. Sites change frequently and you will be changing your code frequently. This is a large part of the challenge.

There are a lot of moving parts involved in scraping a modern website, good test practices will help a lot. Many of the bugs you will encounter while writing this type of code will be the type that just return corrupted data silently. Without good tests to check for regressions you will find out that you've been saving useless corrupted data to your database for a while without noticing. This project will make you very familiar with data validation (find some good libraries to use) and testing. There are not many other problems that combine requiring comprehensive tests and being very difficult to test.

The second part of your tests involve caching and change detection. While writing your code you don't want to be hammering the server for the same page over and over again for no reason. While running your unit tests you want to know if your tests are failing because you broke your code or because the website has been redesigned. Run your unit tests against a cached copy of the urls involved. A caching proxy is very useful here but tricky to configure and use properly.

You also do want to know if the site has changed. If they redesigned the site and your crawler is broken your unit tests will still pass because they are running against a cached copy! You will need either another, smaller set of integration tests that are run infrequently against the live site or good logging and error detection in your crawling code that logs the exact issues, alerts you to the problem and stops crawling. Now you can update your cache, run your unit tests and see what you need to change.

Legal Issues

The law here can be slightly dangerous if you do stupid things. If the law gets involved you are dealing with people who regularly refer to wget and curl as "hacking tools". You don't want this.

The ethical reality of the situation is that there is no difference between using browser software to request a url and look at some data and using your own software to request a url and look at some data. Google is the largest scraping company in the world and they are loved for it. Identifying your bots name in the user agent and being open about the goals and intentions of your web crawler will help here as the law understands what Google is. If you are doing anything shady, like creating fake user accounts or accessing areas of the site that you shouldn't (either "blocked" by robots.txt or because of some kind of authorization exploit) then be aware that you are doing something unethical and the law's ignorance of technology will be extraordinarily dangerous here. It's a ridiculous situation but it's a real one.

It's literally possible to try and build a new search engine on the up and up as an upstanding citizen, make a mistake or have a bug in your software and be seen as a hacker. Not something you want considering the current political reality.

Who am I to write this giant wall of text anyway?

I've written a lot of web crawling related code in my life. I've been doing web related software development for more than a decade as a consultant, employee and startup founder. The early days were writing perl crawlers/scrapers and php websites. When we were embedding hidden iframes loading csv data into webpages to do ajax before Jesse James Garrett named it ajax, before XMLHTTPRequest was an idea. Before jQuery, before json. I'm in my mid-30's, that's apparently considered ancient for this business.

I've written large scale crawling/scraping systems twice, once for a large team at a media company (in Perl) and recently for a small team as the CTO of a search engine startup (in Python/Javascript). I currently work as a consultant, mostly coding in Clojure/Clojurescript (a wonderful expert language in general and has libraries that make crawler/scraper problems a delight)

I've written successful anti-crawling software systems as well. It's remarkably easy to write nigh-unscrapable sites if you want to or to identify and sabotage bots you don't like.

I like writing crawlers, scrapers and parsers more than any other type of software. It's challenging, fun and can be used to create amazing things.

If I get you correctly you have just downloaded Android sdk and want to configure it working with Eclipse. I think you miss one step from the installation of the sdk:
1) you download it
2) you extract it somewhere
3) then go to the specified directory and start AndroidManager (or was it just android??). There you specify you need platform-tools and the manager will configure that for you. This will also provide you with the 'adb' executable which is crucial for the Android developement.

After that you install ADT (which I think you already did) and from Eclipse preferences -> Android options you get a place to specify where your android-sdk is. If you specify it after you did the 'step 3' you should be good to go.

I am not 100% sure I got it correctly and what your state is, so please forgive me if my comment is irrelevant. If I am wrong I will be happy to help if you provide some more details.

Something I am completely sure is that you shouldn't need to create the folder 'tools' by yourself.

PS: The description I gave is for newer versions of android sdk, but if you are encountering a problem with older version I will recommend you to start from scratch with newer version. It shouldn't take you that long time.

To add the contents of one list to another list which already exists, you can use:

targetList.AddRange(sourceList);

If you're just wanting to create a new copy of the list, see Lasse's answer.

From http://sed.sourceforge.net/sed1line.txt: (Please don't ask me how this works ;-) )

 # delete duplicate, consecutive lines from a file (emulates "uniq").
 # First line in a set of duplicate lines is kept, rest are deleted.
 sed '$!N; /^\(.*\)\n\1$/!P; D'

 # delete duplicate, nonconsecutive lines from a file. Beware not to
 # overflow the buffer size of the hold space, or else use GNU sed.
 sed -n 'G; s/\n/&&/; /^\([ -~]*\n\).*\n\1/d; s/\n//; h; P'

Installing libgl1-mesa-dev from the Ubuntu repo resolved this problem for me.

I had to rescale the bitmap a bit to not exceed the 1mb limit of the transaction binder. You can adapt the 400 the your screen or make it dinamic it's just meant to be an example. It works fine and the quality is nice. Its also a lot faster then saving the image and loading it after but you have the size limitation.

public void loadNextActivity(){
    Intent confirmBMP = new Intent(this,ConfirmBMPActivity.class);

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    Bitmap bmp = returnScaledBMP();
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);

    confirmBMP.putExtra("Bitmap",bmp);
    startActivity(confirmBMP);
    finish();

}
public Bitmap returnScaledBMP(){
    Bitmap bmp=null;
    bmp = tempBitmap;
    bmp = createScaledBitmapKeepingAspectRatio(bmp,400);
    return bmp;

}

After you recover the bmp in your nextActivity with the following code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_confirmBMP);
    Intent intent = getIntent();
    Bitmap bitmap = (Bitmap) intent.getParcelableExtra("Bitmap");

}

I hope my answer was somehow helpfull. Greetings

AND and OR are just syntactic sugar for && and ||, like in JavaScript, or other C styled syntax languages.

It appears AND and OR have lower precedence than their C style equivalents.

using threads is made possible by the pthreads PECL extension

http://www.php.net/manual/en/book.pthreads.php

...and in case you wanted to link your main statically, in your Jamfile add the following to requirements:

<link>static
<library>/boost/system//boost_system

and perhaps also:

<linkflags>-static-libgcc
<linkflags>-static-libstdc++

If you do not mind using powershell within batch script:

@echo off

set end_date=%date% %time%
powershell -command "&{$start_date1 = [datetime]::parse('%start_date%'); $end_date1 = [datetime]::parse('%date% %time%'); echo (-join('Duration in seconds: ', ($end_date1 - $start_date1).TotalSeconds)); }"

Use gv$session for RAC, if you want get the total number of session across the cluster.

To avoid syntax errors, be sure to always put BEGIN and END after an IF clause, eg:

IF (@A!= @SA)
   BEGIN
   --do stuff
   END
IF (@C!= @SC)
   BEGIN
   --do stuff
   END

... and so on. This should work as expected. Imagine BEGIN and END keyword as the opening and closing bracket, respectively.

Although I am very late to this but after seeing some legitimate questions for those who wanted to use INSERT-SELECT query with GROUP BY clause, I came up with the work around for this.

Taking further the answer of Marcus Adams and accounting GROUP BY in it, this is how I would solve the problem by using Subqueries in the FROM Clause

Use java-google-translate-text-to-speech instead of Google Translate API v2 Java.

About java-google-translate-text-to-speech

Api unofficial with the main features of Google Translate in Java.

Easy to use!

It also provide text to speech api. If you want to translate the text "Hello!" in Romanian just write:

Translator translate = Translator.getInstance();
String text = translate.translate("Hello!", Language.ENGLISH, Language.ROMANIAN);
System.out.println(text); // "Buna ziua!" 

It's free!

As @r0ast3d correctly said:

Important: Google Translate API v2 is now available as a paid service. The courtesy limit for existing Translate API v2 projects created prior to August 24, 2011 will be reduced to zero on December 1, 2011. In addition, the number of requests your application can make per day will be limited.

This is correct: just see the official page:

Google Translate API is available as a paid service. See the Pricing and FAQ pages for details.

BUT, java-google-translate-text-to-speech is FREE!

Example!

I've created a sample application that demonstrates that this works. Try it here: https://github.com/IonicaBizau/text-to-speech

It was bothering me that implementing a listener for all of my EditText fields required me to have ugly, verbose code so I wrote the below class. May be useful to anyone stumbling upon this.

public abstract class TextChangedListener<T> implements TextWatcher {
    private T target;

    public TextChangedListener(T target) {
        this.target = target;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}

    @Override
    public void afterTextChanged(Editable s) {
        this.onTextChanged(target, s);
    }

    public abstract void onTextChanged(T target, Editable s);
}

Now implementing a listener is a little bit cleaner.

editText.addTextChangedListener(new TextChangedListener<EditText>(editText) {
            @Override
            public void onTextChanged(EditText target, Editable s) {
                //Do stuff
            }
        });

As for how often it fires, one could maybe implement a check to run their desired code in //Do stuff after a given a

Use $dirty flag to show the error only after user interacted with the input:

<div>
  <input type="email" name="email" ng-model="user.email" required />
  <span ng-show="form.email.$dirty && form.email.$error.required">Email is required</span>
</div>

If you want to trigger the errors only after the user has submitted the form than you may use a separate flag variable as in:

<form ng-submit="submit()" name="form" ng-controller="MyCtrl">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="(form.email.$dirty || submitted) && form.email.$error.required">
      Email is required
    </span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  } 
};

Then, if all that JS inside ng-showexpression looks too much for you, you can abstract it into a separate method:

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  }

  $scope.hasError = function(field, validation){
    if(validation){
      return ($scope.form[field].$dirty && $scope.form[field].$error[validation]) || ($scope.submitted && $scope.form[field].$error[validation]);
    }
    return ($scope.form[field].$dirty && $scope.form[field].$invalid) || ($scope.submitted && $scope.form[field].$invalid);
  };

};

<form ng-submit="submit()" name="form">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="hasError('email', 'required')">required</span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

Workaround to pass variable like by reference:

var a = 1;
inc = function(variableName) {
  window[variableName] += 1;
};

inc('a');

alert(a); // 2

And yup, actually you can do it without access a global variable:

inc = (function () {
    var variableName = 0;

    var init = function () {
        variableName += 1;
        alert(variableName);
    }

    return init;
})();

inc();

in addition, you can drop multiple partitions from one statement (Dropping multiple partitions in Impala/Hive).

Extract from above link:

hive> alter table t drop if exists partition (p=1),partition (p=2),partition(p=3);
Dropped the partition p=1
Dropped the partition p=2
Dropped the partition p=3
OK

EDIT 1:

Also, you can drop bulk using a condition sign (>,<,<>), for example:

Alter table t 
drop partition (PART_COL>1);

Here's a short example, that creates and array of objects, and sorts numerically or alphabetically:

// Create Objects Array

var arrayCarObjects = [
{brand: "Honda",        topSpeed: 45},
{brand: "Ford",         topSpeed: 6},
{brand: "Toyota",       topSpeed: 240},
{brand: "Chevrolet",    topSpeed: 120},
{brand: "Ferrari",      topSpeed: 1000}
];

// Sort Objects Numerically

arrayCarObjects.sort((a, b) => (a.topSpeed - b.topSpeed));

// Sort Objects Alphabetically

arrayCarObjects.sort((a, b) => (a.brand > b.brand) ? 1 : -1);

It would be nice if there were some way of turning off "throw on non-success code" but if you catch WebException you can at least use the response:

using System;
using System.IO;
using System.Web;
using System.Net;

public class Test
{
    static void Main()
    {
        WebRequest request = WebRequest.Create("http://csharpindepth.com/asd");
        try
        {
            using (WebResponse response = request.GetResponse())
            {
                Console.WriteLine("Won't get here");
            }
        }
        catch (WebException e)
        {
            using (WebResponse response = e.Response)
            {
                HttpWebResponse httpResponse = (HttpWebResponse) response;
                Console.WriteLine("Error code: {0}", httpResponse.StatusCode);
                using (Stream data = response.GetResponseStream())
                using (var reader = new StreamReader(data))
                {
                    string text = reader.ReadToEnd();
                    Console.WriteLine(text);
                }
            }
        }
    }
}

You might like to encapsulate the "get me a response even if it's not a success code" bit in a separate method. (I'd suggest you still throw if there isn't a response, e.g. if you couldn't connect.)

If the error response may be large (which is unusual) you may want to tweak HttpWebRequest.DefaultMaximumErrorResponseLength to make sure you get the whole error.

This solution is very similar to that provided by @gdw2 , only that the string formatting is correctly done to match what you asked for - "Should be as compact as possible"

>>> import datetime
>>> a = datetime.datetime.now()
>>> "%s:%s.%s" % (a.minute, a.second, str(a.microsecond)[:2])
'31:45.57'

For Laravel version >=5.1

storage_path()

The storage_path function returns the fully qualified path to the storage directory:

$path = storage_path();

You may also use the storage_path function to generate a fully qualified path to a given file relative to the storage directory:

$app_path = storage_path('app');
$file_path = storage_path('app/file.txt');

Simple Explanation by analogy

Imagine you are in a bank, trying to get some money out of your account. But it's dark; the bank is pitch black: there's no light and you can't see your hand in front of your face. You are surrounded by another 20 people. They all look the same. And everybody has the same voice. And everyone is a potential bad guy. In other words, HTTP is stateless.

This bank is a funny type of bank - for the sake of argument here's how things work:

1. you wait in line (or on-line) and you talk to the teller: you make a request to withdraw money, and then
2. you have to wait briefly on the sofa, and 20 minutes later
3. you have to go and actually collect your money from the teller.

But how will the teller tell you apart from everyone else?

The teller can't see or readily recognise you, remember, because the lights are all out. What if your teller gives your $10,000 withdrawal to someone else - the wrong person?! It's absolutely vital that the teller can recognise you as the one who made the withdrawal, so that you can get the money (or resource) that you asked for.

Solution:

When you first appear to the teller, he or she tells you something in secret:

"When ever you are talking to me," says the teller, "you should first identify yourlself as GNASHEU329 - that way I know it's you".

Nobody else knows the secret passcode.

Example of How I Withdrew Cash:

So I decide to go to and chill out for 20 minutes and then later i go to the teller and say "I'd like to collect my withdrawal"

The teller asks me: "who are you??!"

"It's me, Mr George Banks!"

"Prove it!"

And then I tell them my passcode: GNASHEU329

"Certainly Mr Banks!"

That basically is how a session works. It allows one to be uniquely identified in a sea of millions of people. You need to identify yourself every time you deal with the teller.

If you got any questions or are unclear - please post comment and i will try to clear it up for you. The following is not strictly speaking, completely accurate in its terminology, but I hope it's helpful to you in understanding concepts.

Explanation via Pictures:

Did you try this?

UPDATE table 
SET col1 = NULL 
WHERE col1 = ''

As the commenters point out, you don't have to do ltrim() or rtrim(), and NULL columns will not match ''.

public static void main(String[] args) {
    double g = 1 / 3;
    System.out.printf("%.2f", g);
}

Since both 1 and 3 are ints the result not rounded but it's truncated. So you ignore fractions and take only wholes.

To avoid this have at least one of your numbers 1 or 3 as a decimal form 1.0 and/or 3.0.

I'm using this solution:

@interface Model
+ (int) value;
+ (void) setValue:(int)val;
@end

@implementation Model
static int value;
+ (int) value
{ @synchronized(self) { return value; } }
+ (void) setValue:(int)val
{ @synchronized(self) { value = val; } }
@end

And i found it extremely useful as a replacement of Singleton pattern.

To use it, simply access your data with dot notation:

Model.value = 1;
NSLog(@"%d = value", Model.value);

Actually, you have to explicitly compare it to true. If the dialog doesn't exist yet, it will not return false (as you would expect), it will return a DOM object.

if ($('#mydialog').dialog('isOpen') === true) {
    // true
} else {
    // false
}

@Jacob Dalton has mentioned this in a comment, but nobody seems to have mentioned in an answer that vim has to be compiled with clipboard support for any of the suggestions mentioned here to work. Mine wasn't configured that way on Mac OS X by default and I had to rebuild vim. Use this the command to find out whether you have it or not vim --version | grep 'clipboard'. +clipboard means you're good and the suggestions here will work for you, while -clipboard means you have to recompile and rebuild vim.

First Way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Second way:

You created an empty file with the desired name, which then prevented you from creating the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Third way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Fourth Way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Fifth way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Correct way:

1. Create a File for your desired directory (e.g., File path=new File(getFilesDir(),"myfolder");)
2. Call mkdirs() on that File to create the directory if it does not exist
3. Create a File for the output file (e.g., File mypath=new File(path,"myfile.txt");)
4. Use standard Java I/O to write to that File (e.g., using new BufferedWriter(new FileWriter(mypath)))

You didn't say what's currently your .gitignore, but a .gitignore with the following contents in your root directory should do the trick.

.metadata
build

You have two typing errors in your code:

 struct timeval,

should be

 struct timeval

and after the printf() parenthesis you need a semicolon.

Also, depending on the compiler, so simple a cycle might just be optimized out, giving you a time of 0 microseconds whatever you do.

Finally, the time calculation is wrong. You only take into accounts the seconds, ignoring the microseconds. You need to get the difference between seconds, multiply by one million, then add "after" tv_usec and subtract "before" tv_usec. You gain nothing by casting an integer number of seconds to a float.

I'd suggest checking out the man page for struct timeval.

This is the code:

#include <stdio.h>
#include <sys/time.h>

int main (int argc, char** argv) {
    struct timeval tvalBefore, tvalAfter;  // removed comma

    gettimeofday (&tvalBefore, NULL);
    int i =0;
    while ( i < 10000) {
        i ++;
    }

    gettimeofday (&tvalAfter, NULL);

    // Changed format to long int (%ld), changed time calculation

    printf("Time in microseconds: %ld microseconds\n",
            ((tvalAfter.tv_sec - tvalBefore.tv_sec)*1000000L
           +tvalAfter.tv_usec) - tvalBefore.tv_usec
          ); // Added semicolon
    return 0;
}

If you are using Python selenium bindings, nowadays, there is an extension to selenium - selenium-requests:

Extends Selenium WebDriver classes to include the request function from the Requests library, while doing all the needed cookie and request headers handling.

Example:

from seleniumrequests import Firefox

webdriver = Firefox()
response = webdriver.request('POST', 'url here', data={"param1": "value1"})
print(response)

but I can't initialize my derived class, I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ?? so I'm thinking maybe in the PetStore default constructor I can call Farm()... so any Idea ???

Don't panic.

Farm constructor will be called in the constructor of PetStore, automatically.

See the base class inheritance calling rules: What are the rules for calling the superclass constructor?

See ?read.table. Basically, when you use read.table, you specify a number indicating the column:

##Row names in the first column
read.table(filname.txt, row.names=1)

I am from .net background. However, java/c# are more/less same.

If you instantiate a non-primitive type (array in your case), it won't be null.
e.g. int[] numbers = new int[3];
In this case, the space is allocated & each of the element has a default value of 0.

It will be null, when you don't new it up.
e.g.

int[] numbers = null; // changed as per @Joachim's suggestion.
if (numbers == null)
{
   System.out.println("yes, it is null. Please new it up");
}

How about this? I frequently use the CSS Flexible Box Layout to center something.

<div style="display: flex; justify-content: center;">_x000D_
  <img src="http://icons.iconarchive.com/icons/rokey/popo-emotions/128/big-smile-icon.png" style="width: 40px; height: 40px;" />_x000D_
</div>

Selecting N random items from a group shouldn't have anything to do with order! Randomness is about unpredictability and not about shuffling positions in a group. All the answers that deal with some kinda ordering is bound to be less efficient than the ones that do not. Since efficiency is the key here, I will post something that doesn't change the order of items too much.

1) If you need true random values which means there is no restriction on which elements to choose from (ie, once chosen item can be reselected):

public static List<T> GetTrueRandom<T>(this IList<T> source, int count, 
                                       bool throwArgumentOutOfRangeException = true)
{
    if (throwArgumentOutOfRangeException && count > source.Count)
        throw new ArgumentOutOfRangeException();

    var randoms = new List<T>(count);
    randoms.AddRandomly(source, count);
    return randoms;
}

If you set the exception flag off, then you can choose random items any number of times.

If you have { 1, 2, 3, 4 }, then it can give { 1, 4, 4 }, { 1, 4, 3 } etc for 3 items or even { 1, 4, 3, 2, 4 } for 5 items!

This should be pretty fast, as it has nothing to check.

2) If you need individual members from the group with no repetition, then I would rely on a dictionary (as many have pointed out already).

public static List<T> GetDistinctRandom<T>(this IList<T> source, int count)
{
    if (count > source.Count)
        throw new ArgumentOutOfRangeException();

    if (count == source.Count)
        return new List<T>(source);

    var sourceDict = source.ToIndexedDictionary();

    if (count > source.Count / 2)
    {
        while (sourceDict.Count > count)
            sourceDict.Remove(source.GetRandomIndex());

        return sourceDict.Select(kvp => kvp.Value).ToList();
    }

    var randomDict = new Dictionary<int, T>(count);
    while (randomDict.Count < count)
    {
        int key = source.GetRandomIndex();
        if (!randomDict.ContainsKey(key))
            randomDict.Add(key, sourceDict[key]);
    }

    return randomDict.Select(kvp => kvp.Value).ToList();
}

The code is a bit lengthier than other dictionary approaches here because I'm not only adding, but also removing from list, so its kinda two loops. You can see here that I have not reordered anything at all when count becomes equal to source.Count. That's because I believe randomness should be in the returned set as a whole. I mean if you want 5 random items from 1, 2, 3, 4, 5, it shouldn't matter if its 1, 3, 4, 2, 5 or 1, 2, 3, 4, 5, but if you need 4 items from the same set, then it should unpredictably yield in 1, 2, 3, 4, 1, 3, 5, 2, 2, 3, 5, 4 etc. Secondly, when the count of random items to be returned is more than half of the original group, then its easier to remove source.Count - count items from the group than adding count items. For performance reasons I have used source instead of sourceDict to get then random index in the remove method.

So if you have { 1, 2, 3, 4 }, this can end up in { 1, 2, 3 }, { 3, 4, 1 } etc for 3 items.

3) If you need truly distinct random values from your group by taking into account the duplicates in the original group, then you may use the same approach as above, but a HashSet will be lighter than a dictionary.

public static List<T> GetTrueDistinctRandom<T>(this IList<T> source, int count, 
                                               bool throwArgumentOutOfRangeException = true)
{
    if (count > source.Count)
        throw new ArgumentOutOfRangeException();

    var set = new HashSet<T>(source);

    if (throwArgumentOutOfRangeException && count > set.Count)
        throw new ArgumentOutOfRangeException();

    List<T> list = hash.ToList();

    if (count >= set.Count)
        return list;

    if (count > set.Count / 2)
    {
        while (set.Count > count)
            set.Remove(list.GetRandom());

        return set.ToList();
    }

    var randoms = new HashSet<T>();
    randoms.AddRandomly(list, count);
    return randoms.ToList();
}

The randoms variable is made a HashSet to avoid duplicates being added in the rarest of rarest cases where Random.Next can yield the same value, especially when input list is small.

So { 1, 2, 2, 4 } => 3 random items => { 1, 2, 4 } and never { 1, 2, 2}

{ 1, 2, 2, 4 } => 4 random items => exception!! or { 1, 2, 4 } depending on the flag set.

Some of the extension methods I have used:

static Random rnd = new Random();
public static int GetRandomIndex<T>(this ICollection<T> source)
{
    return rnd.Next(source.Count);
}

public static T GetRandom<T>(this IList<T> source)
{
    return source[source.GetRandomIndex()];
}

static void AddRandomly<T>(this ICollection<T> toCol, IList<T> fromList, int count)
{
    while (toCol.Count < count)
        toCol.Add(fromList.GetRandom());
}

public static Dictionary<int, T> ToIndexedDictionary<T>(this IEnumerable<T> lst)
{
    return lst.ToIndexedDictionary(t => t);
}

public static Dictionary<int, T> ToIndexedDictionary<S, T>(this IEnumerable<S> lst, 
                                                           Func<S, T> valueSelector)
{
    int index = -1;
    return lst.ToDictionary(t => ++index, valueSelector);
}

If its all about performance with tens of 1000s of items in the list having to be iterated 10000 times, then you may want to have faster random class than System.Random, but I don't think that's a big deal considering the latter most probably is never a bottleneck, its quite fast enough..

Edit: If you need to re-arrange order of returned items as well, then there's nothing that can beat dhakim's Fisher-Yates approach - short, sweet and simple..

format = '%Y-%m-%d %H:%M %p'

The format is using %H instead of %I. Since %H is the "24-hour" format, it's likely just discarding the %p information. It works just fine if you change the %H to %I.

Using awk.

i starts at 0, i++ will increment the value of i, but return the original value that i held before being incremented.

awk '{print i++ "," $0}' file

Below is the example which passes value on onClick event.

I used es6 syntax. remember in class component arrow function does not bind automatically, so explicitly binding in constructor.

class HeaderRows extends React.Component {

    constructor(props) {
        super(props);
        this.handleSort = this.handleSort.bind(this);
    }

    handleSort(value) {
        console.log(value);
    }

    render() {
        return(
            <tr>
                {this.props.defaultColumns.map( (column, index) =>
                    <th value={ column } 
                        key={ index } 
                        onClick={ () => this.handleSort(event.target.value) }>
                        { column }
                    </th>
                )}

                {this.props.externalColumns.map((column, index)  =>
                    <th value ={ column[0] }
                        key={ index }>
                        {column[0]}
                    </th>
                )}
            </tr>
         );
    }
}

Another simple solution (not very elegant, but not too ugly also) is to place a inner div / span then get his height ($(this).find('span).height()).

Here is an example of using this strategy:

$(".more").click(function(){_x000D_
if($(this).parent().find('.showMore').length) {_x000D_
$(this).parent().find('.showMore').removeClass('showMore').css('max-height','90px');_x000D_
$(this).parent().find('.more').removeClass('less').text('More');_x000D_
} else {_x000D_
$(this).parent().find('.text').addClass('showMore').css('max-height',$(this).parent().find('span').height());_x000D_
$(this).parent().find('.more').addClass('less').text('Less');_x000D_
}_x000D_
});

* {transition: all 0.5s;}_x000D_
.text {position:relative;width:400px;max-height:90px;overflow:hidden;}_x000D_
.showMore {}_x000D_
.text::after {_x000D_
  content: "";_x000D_
    position: absolute; bottom: 0; left: 0;_x000D_
        box-shadow: inset 0 -26px 22px -17px #fff;_x000D_
    height: 39px;_x000D_
  z-index:99999;_x000D_
  width:100%;_x000D_
  opacity:1;_x000D_

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum._x000D_

For chrome v72+ what solved it for me was only this:

go to chrome://flags/ and disable this 3 flags

• Disable site isolation
• Enable network service
• Runs network service in-process

or you can do it from command line :

chrome --disable-site-isolation-trials --disable-features=NetworkService,NetworkServiceInProcess

why this happen?

It seems that Google is refactoring their Chromium engine into modular structure, where different services will be separated into stand-alone modules and processes. They call this process servicification. Network service is the first step, Ui service, Identity service and Device service are coming up. Google provides the official information at the Chromium project site.

is it dangerous to change that?

An example is networking: once we have a network service we can choose to run it out of process for better stability/security, or in-process if we're resource constrained. source

It is a decorator that can be called in a variety of ways (tested in python3.7):

import functools


def my_decorator(*args_or_func, **decorator_kwargs):

    def _decorator(func):

        @functools.wraps(func)
        def wrapper(*args, **kwargs):

            if not args_or_func or callable(args_or_func[0]):
                # Here you can set default values for positional arguments
                decorator_args = ()
            else:
                decorator_args = args_or_func

            print(

            result = func(*args, **kwargs)
            # ...

            return result

        return wrapper

    return _decorator(args_or_func[0]) \

Another solution, that truncates and round:

function round (number, decimals, truncate) {
    if (truncate) {
        number = number.toFixed(decimals + 1);
        return parseFloat(number.slice(0, -1));
    }

    var n = Math.pow(10.0, decimals);
    return Math.round(number * n) / n;
};

IPv4 uses 32 bits, in the form of:

255.255.255.255

I suppose it depends on your datatype, whether you're just storing as a string with a CHAR type or if you're using a numerical type.

IPv6 uses 128 bits. You won't have IPs longer than that unless you're including other information with them.

IPv6 is grouped into sets of 4 hex digits seperated by colons, like (from wikipedia):

2001:0db8:85a3:0000:0000:8a2e:0370:7334

You're safe storing it as a 39-character long string, should you wish to do that. There are other shorthand ways to write addresses as well though. Sets of zeros can be truncated to a single 0, or sets of zeroes can be hidden completely by a double colon.

String.prototype.trim = function(){return his.replace(/^\s+|\s+$/g,"");}
function getHost(url){
    if("undefined"==typeof(url)||null==url) return "";
    url = url.trim(); if(""==url) return "";
    var _host,_arr;
    if(-1<url.indexOf("://")){
        _arr = url.split('://');
        if(-1<_arr[0].indexOf("/")||-1<_arr[0].indexOf(".")||-1<_arr[0].indexOf("\?")||-1<_arr[0].indexOf("\&")){
            _arr[0] = _arr[0].trim();
            if(0==_arr[0].indexOf("//")) _host = _arr[0].split("//")[1].split("/")[0].trim().split("\?")[0].split("\&")[0];
            else return "";
        }
        else{
            _arr[1] = _arr[1].trim();
            _host = _arr[1].split("/")[0].trim().split("\?")[0].split("\&")[0];
        }
    }
    else{
        if(0==url.indexOf("//")) _host = url.split("//")[1].split("/")[0].trim().split("\?")[0].split("\&")[0];
        else return "";
    }
    return _host;
}
function getHostname(url){
    if("undefined"==typeof(url)||null==url) return "";
    url = url.trim(); if(""==url) return "";
    return getHost(url).split(':')[0];
}
function getDomain(url){
    if("undefined"==typeof(url)||null==url) return "";
    url = url.trim(); if(""==url) return "";
    return getHostname(url).replace(/([a-zA-Z0-9]+.)/,"");
}

Shorter version:

db.row_factory = lambda c, r: dict([(col[0], r[idx]) for idx, col in enumerate(c.description)])

As far as I understand, you create a Movie class:

class Movie
{
private:
  std::string _title;
  std::string _director;
  int         _year;
  int         _rating;
  std::vector<std::string> actors;
};

and having such class, you create a vector instance:

std::vector<Movie*> movies;

so, you can add any movie to your movies collection. Since you are creating a vector of pointers to movies, do not forget to free the resources allocated by your movie instances OR you could use some smart pointer to deallocate the movies automatically:

std::vector<shared_ptr<Movie>> movies;

I had to encounter a situation as such, and simply, the

str_replace("\/","/",$variable)

did work for me.

Visual Studio 2019 update:

Now vs has built-in terminal

View > Terminal (Ctrl+")

To change default terminal

Tools > Options - Terminal > Set As Default

Before Visual Studio 2019

From comments best answer is from @Hans Passant

1. Add an external tool.

Tools > External Tools > Add

Title: Terminal (or name it yourself)

Command=cmd.exe Or Command=powershell.exe

Arguments= /k

Initial Directory=$(ProjectDir)

2. Tools > Terminal (or whatever you put in title)

3. Enjoy!

if you want, you can use a saveActions plugin. You can reformat file, optimized the imports and more things, it's really customizable and easy to setup.

Here is the method which is used in Commerce SagePay and in Commerce Paypoint Drupal modules which basically compares document.location.href with the old value by first loading its own iframe, then external one.

So basically the idea is to load the blank page as a placeholder with its own JS code and hidden form. Then parent JS code will submit that hidden form where its #action points to the external iframe. Once the redirect/submit happens, the JS code which still running on that page can track your document.location.href value changes.

Here is example JS used in iframe:

;(function($) {
  Drupal.behaviors.commercePayPointIFrame = {
    attach: function (context, settings) {
      if (top.location != location) {
        $('html').hide();
        top.location.href = document.location.href;
      }
    }
  }
})(jQuery);

And here is JS used in parent page:

;(function($) {
  /**
   * Automatically submit the hidden form that points to the iframe.
   */
  Drupal.behaviors.commercePayPoint = {
    attach: function (context, settings) {
      $('div.payment-redirect-form form', context).submit();
      $('div.payment-redirect-form #edit-submit', context).hide();
      $('div.payment-redirect-form .checkout-help', context).hide();
    }
  }
})(jQuery);

Then in temporary blank landing page you need to include the form which will redirect to the external page.

It could be not a problem with a single line of your code.

On some devices (I don't recall if it is in stock Android) the Permission dialog includes a check box labeled "Never ask again". If you click Deny with the box checked then you won't be prompted again for that permission, it will automatically be denied to the app. To revert this, you have to go into Settings -> App -> Permissions and re--enable that perm for the app. Then turn it off to deny it again. You may have to open the app before turning it off again, not sure.

I don't know if your Nexus has it. Maybe worth a try.

If anyone is looking for a simple solution in Laravel 5.3:

1. Let default timestamps() be saved as is i.e. '2016-11-14 12:19:49'

2. In your views, format the field as below (or as required):

   date('F d, Y', strtotime($list->created_at))
   

It worked for me very well for me.

Seeing it in action might help you better understanding the difference.

Assuming we're working on master branch and have a file hello.txt that contains "Hello" string.

Let's modify the file and add " world" string to it. Now you want to move to a different branch to fix a minor bug you've just found, so you need to stash your changes:

git stash

You moved to the other branch, fixed the bug and now you're ready to continue working on your master branch, so you pop the changes:

git stash pop

Now if you try to review the stash content you'll get:

$ git stash show -p
No stash found.

However, if you use git stash apply instead, you'll get the stashed content but you'll also keep it:

$ git stash show -p
diff --git a/hello.txt b/hello.txt
index e965047..802992c 100644
--- a/hello.txt
+++ b/hello.txt
@@ -1 +1 @@
-Hello
+Hello world

So pop is just like stack's pop - it actually removes the element once it's popped, while apply is more like peek.

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

I just imported ClarityModule and it solved all the problems. Give it a try!

import { ClarityModule } from 'clarity-angular';

Also, include the module in the imports.

In Doctrine 2.x you can't pass multiple order by using doctrine 'orderBy' or 'addOrderBy' as above examples. Because, it automatically adds the 'ASC' at the end of the last column name when you left the second parameter blank, such as in the 'orderBy' function.

For an example ->orderBy('a.fist_name ASC, a.last_name ASC') will output SQL something like this 'ORDER BY first_name ASC, last_name ASC ASC'. So this is SQL syntax error. Simply because default of the orderBy or addOrderBy is 'ASC'.

To add multiple order by's you need to use 'add' function. And it will be like this.

->add('orderBy','first_name ASC, last_name ASC'). This will give you the correctly formatted SQL.

Please see https://github.com/joshua-gould/canvas2pdf. This library creates a PDF representation of your canvas element, unlike the other proposed solutions which embed an image in a PDF document.

//Create a new PDF canvas context.
var ctx = new canvas2pdf.Context(blobStream());

//draw your canvas like you would normally
ctx.fillStyle='yellow';
ctx.fillRect(100,100,100,100);
// more canvas drawing, etc...

//convert your PDF to a Blob and save to file
ctx.stream.on('finish', function () {
    var blob = ctx.stream.toBlob('application/pdf');
    saveAs(blob, 'example.pdf', true);
});
ctx.end();

You can use attachEvent(ie8) and addEventListener instead

addEvent(window, 'load', function(){ some_methods_1() });
addEvent(window, 'load', function(){ some_methods_2() });

function addEvent(element, eventName, fn) {
    if (element.addEventListener)
        element.addEventListener(eventName, fn, false);
    else if (element.attachEvent)
        element.attachEvent('on' + eventName, fn);
}

You could use a template like :

#include <iostream>
using std::cerr;
using std::endl;

//qt4type
typedef unsigned int quint32;

template <typename T>
void deletep(T &) {}
template <typename T>
void deletep(T* & ptr) {
    delete ptr;
    ptr = 0;
}
template<typename T>
class Matrix {
    public:
        typedef T value_type;
        Matrix() : _cols(0), _rows(0), _data(new T[0]), auto_delete(true) {};
        Matrix(quint32 rows, quint32 cols, bool auto_del = true);

        bool exists(quint32 row, quint32 col) const;
        T & operator()(quint32 row, quint32 col);
        T operator()(quint32 row, quint32 col) const;
        virtual ~Matrix();

        int size() const { return _rows * _cols; }
        int rows() const { return _rows; }
        int cols() const { return _cols; }
    private:
        Matrix(const Matrix &);
        quint32 _rows, _cols;
        mutable T * _data;
        const bool auto_delete;
};
template<typename T>
Matrix<T>::Matrix(quint32 rows, quint32 cols, bool auto_del) : _rows(rows), _cols(cols), auto_delete(auto_del) {
    _data = new T[rows * cols];
}
template<typename T>
inline T & Matrix<T>::operator()(quint32 row, quint32 col) {
    return _data[_cols * row + col];
}
template<typename T>
inline T Matrix<T>::operator()(quint32 row, quint32 col) const {
    return _data[_cols * row + col];
}

template<typename T>
bool Matrix<T>::exists(quint32 row, quint32 col) const {
    return (row < _rows && col < _cols);
}

template<typename T>
Matrix<T>::~Matrix() {
    if(auto_delete){
        for(int i = 0, c = size(); i < c; ++i){
            //will do nothing if T isn't a pointer
            deletep(_data[i]);
        }
    }
    delete [] _data;
}

int main() {
    Matrix< int > m(10,10);
    quint32 i = 0;
    for(int x = 0; x < 10; ++x) {
        for(int y = 0; y < 10; ++y, ++i) {
            m(x, y) = i;
        }
    }
    for(int x = 0; x < 10; ++x) {
        for(int y = 0; y < 10; ++y) {
            cerr << "@(" << x << ", " << y << ") : " << m(x,y) << endl;
        }
    }
}

*edit, fixed a typo.

Run a packet sniffer (e.g., Wireshark) also on the peer to see whether it's the peer who's sending the RST or someone in the middle.

Just to add to the other answers, there are still noteworthy differences here, specifically when dealing with <svg> elements.

I have used both .childNodes and .children and have preferred working with the HTMLCollection delivered by the .children getter.

Today however, I ran into issues with IE/Edge failing when using .children on an <svg>. While .children is supported in IE on basic HTML elements, it isn't supported on document/document fragments, or SVG elements.

For me, I was able to simply grab the needed elements via .childNodes[n] because I don't have extraneous text nodes to worry about. You may be able to do the same, but as mentioned elsewhere above, don't forget that you may run into unexpected elements.

Hope this is helpful to someone scratching their head trying to figure out why .children works elsewhere in their js on modern IE and fails on document or SVG elements.

This took me way too long to figure out. I can't believe nobody has mentioned center tags.

Ex:

<center><img src = "yourimage.png"/></center>

and if you want to resize the image to a percentage:

<center><img src = "yourimage.png" width = "75%"/></center>

GG America

I personally like to do it this way:

<input type="checkbox" name="option" value="1" disabled="disabled" />
<input type="hidden" name="option" value="1">

I think this is better for two reasons:

1. User clearly understand that he can't edit this value
2. The value is sent when submitting the form.

Since the command:

fig,ax = plt.subplots(5,2,sharex=True,sharey=True,figsize=fig_size)

you used returns a tuple consisting of the figure and a list of the axes instances, it is already sufficient to do something like (mind that I've changed fig,axto fig,axes):

fig,axes = plt.subplots(5,2,sharex=True,sharey=True,figsize=fig_size)

for ax in axes:
    ax.set_xlabel('Common x-label')
    ax.set_ylabel('Common y-label')

If you happen to want to change some details on a specific subplot, you can access it via axes[i] where i iterates over your subplots.

It might also be very helpful to include a

fig.tight_layout()

at the end of the file, before the plt.show(), in order to avoid overlapping labels.

After 1.13.0, Docker includes a new command docker system df to show docker disk usage.

$ docker system df

Local Volumes   4            1          3.207 GB    2.261 (70%)

To show more detailed information on space usage:

$ docker system df --verbose

At the bottom of the Sublime window, you'll see something representing your tab/space setting.

You'll then get a dropdown with a bunch of options. The options you care about are:

• Convert Indentation to Spaces
• Convert Indentation to Tabs

Apply your desired setting to the entire document.

Despite all the great answers above, I as a security master student and programmer who previously worked at eBay when I took a look into buyer protection and fraud, can say to separate access token and refresh token has its best balance between harassing user of frequent username/password input and keeping the authority in hand to revoke access to potential abuse of your service.

Think of a scenario like this. You issue user of an access token of 3600 seconds and refresh token much longer as one day.

1. The user is a good user, he is at home and gets on/off your website shopping and searching on his iPhone. His IP address doesn't change and have a very low load on your server. Like 3-5 page requests every minute. When his 3600 seconds on the access token is over, he requires a new one with the refresh token. We, on the server side, check his activity history and IP address, think he is a human and behaves himself. We grant him a new access token to continue using our service. The user won't need to enter again the username/password until he has reached one day life-span of refresh token itself.

2. The user is a careless user. He lives in New York, USA and got his virus program shutdown and was hacked by a hacker in Poland. When the hacker got the access token and refresh token, he tries to impersonate the user and use our service. But after the short-live access token expires, when the hacker tries to refresh the access token, we, on the server, has noticed a dramatic IP change in user behavior history (hey, this guy logins in USA and now refresh access in Poland after just 3600s ???). We terminate the refresh process, invalidate the refresh token itself and prompt to enter username/password again.

3. The user is a malicious user. He is intended to abuse our service by calling 1000 times our API each minute using a robot. He can well doing so until 3600 seconds later, when he tries to refresh the access token, we noticed his behavior and think he might not be a human. We reject and terminate the refresh process and ask him to enter username/password again. This might potentially break his robot's automatic flow. At least makes him uncomfortable.

You can see the refresh token has acted perfectly when we try to balance our work, user experience and potential risk of a stolen token. Your watch dog on the server side can check more than IP change, frequency of api calls to determine whether the user shall be a good user or not.

Another word is you can also try to limit the damage control of stolen token/abuse of service by implementing on each api call the basic IP watch dog or any other measures. But this is expensive as you have to read and write record about the user and will slow down your server response.

Java is a compiled programming language, but rather than compile straight to executable machine code, it compiles to an intermediate binary form called JVM byte code. The byte code is then compiled and/or interpreted to run the program.

I guess there is an alternative way to achieve what you are looking for. I don't say its a complete solution but it served the purpose in my case.

What I did is instead of replacing the fragment I just added target fragment. So basically you will be going to use add() method instead replace().

What else I did. I hide my current fragment and also add it to backstack.

Hence it overlaps new fragment over the current fragment without destroying its view.(check that its onDestroyView() method is not being called. Plus adding it to backstate gives me the advantage of resuming the fragment.

Here is the code :

Fragment fragment=new DestinationFragment();
FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction ft=fragmentManager.beginTransaction();
ft.add(R.id.content_frame, fragment);
ft.hide(SourceFragment.this);
ft.addToBackStack(SourceFragment.class.getName());
ft.commit();

AFAIK System only calls onCreateView() if the view is destroyed or not created. But here we have saved the view by not removing it from memory. So it will not create a new view.

And when you get back from Destination Fragment it will pop the last FragmentTransaction removing top fragment which will make the topmost(SourceFragment's) view to appear over the screen.

COMMENT: As I said it is not a complete solution as it doesn't remove the view of Source fragment and hence occupying more memory than usual. But still, serve the purpose. Also, we are using a totally different mechanism of hiding view instead of replacing it which is non traditional.

So it's not really for how you maintain the state, but for how you maintain the view.

you can rename constraint objects using sp_rename (as described in this answer)

for example:

EXEC sp_rename N'schema.MyIOldConstraint', N'MyNewConstraint'

I hope my decision will help. I had a similar error in Laravel. I added a foreign key to the wrong table.
Wrong code:

Schema::create('comments', function (Blueprint $table) {
$table->unsignedBigInteger('post_id')->index()->nullable();
...
$table->foreign('post_id')->references('id')->on('comments')->onDelete('cascade');
    });


Schema::create('posts', function (Blueprint $table) {
    $table->bigIncrements('id');
    ...
    });

Please note to the function on('comments') above. Correct code

 $table->foreign('post_id')->references('id')->on('posts')->onDelete('cascade');

Q: What's the difference between the java.lang.String methods replace() and replaceAll(), other than that the latter uses regex.

A: Just the regex. They both replace all :)

http://docs.oracle.com/javase/8/docs/api/java/lang/String.html

PS:

There's also a replaceFirst() (which takes a regex)

List<String> mockedList = mock(List.class);

List<String> l = new ArrayList();
l.add("someElement");

mockedList.addAll(l);

ArgumentCaptor<List> argumentCaptor = ArgumentCaptor.forClass(List.class);

verify(mockedList).addAll(argumentCaptor.capture());

I believe using * invalidate the entire cache in the distribution. I am trying at the moment, I would update it further

Update:

It worked as expected. Please note that you can invalidate the object you would like by specifying the object path.

How about this way?

['Cat', 'Dog', 'Bird'].index('Dog')

or Simply you can go to the form and when you call the data to be displayed you set the property like datagridview1.columns(0).width = 150 datagridview1.columns(1).width = 150 datagridview1.columns(2).width = 150enter code here

So simple worked so fine with me Bro

I haven’t actually done anything with font-face, so take this with a pinch of salt, but I don’t think there’s any way for the browser to definitively tell if a given web font installed on a user’s machine or not.

The user could, for example, have a different font with the same name installed on their machine. The only way to definitively tell would be to compare the font files to see if they’re identical. And the browser couldn’t do that without downloading your web font first.

Does Firefox download the font when you actually use it in a font declaration? (e.g. h1 { font: 'DejaVu Serif';)?

Bit late but hopefully can still be useful to someone.

2 steps to adding items to a specific position in an ArrayList

1. add null items to a specific index in an ArrayList

2. Then set the positions as and when required.

       list = new ArrayList();//Initialise the ArrayList
   for (Integer i = 0; i < mItems.size(); i++) {
       list.add(i, null); //"Add" all positions to null
   }
      // "Set" Items
       list.set(position, SomeObject);
   

This way you don't have redundant items in the ArrayList i.e. if you were to add items such as,

list = new ArrayList(mItems.size());    
list.add(position, SomeObject);

This would not overwrite existing items in the position merely, shifting existing ones to the right by one - so you have an ArrayList with twice as many indicies.

firstOrCreate() checks for all the arguments to be present before it finds a match. If not all arguments match, then a new instance of the model will be created.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.

The difference between firstOrCreate() and firstOrNew():

• firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
• firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name or some mandatory field), you should use firstOrNew(). If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate().

I had exact same error, I was not giving base package. Giving correct base package,ressolved it.

package com.ymc.backend.ymcbe;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages="com.ymc.backend")
public class YmcbeApplication {

    public static void main(String[] args) {
        SpringApplication.run(YmcbeApplication.class, args);
    }

}

Note: not including .controller @ComponentScan(basePackages="com.ymc.backend.controller") because i have many other component classes which my project does not scan if i just give .controller

Here is my controller sample:

package com.ymc.backend.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@CrossOrigin
@RequestMapping(value = "/user")
public class UserController {

    @PostMapping("/sendOTP")
    public String sendOTP() {
        return "OTP sent";
    };


}

display: block means that the element is displayed as a block, as paragraphs and headers have always been. A block has some whitespace above and below it and tolerates no HTML elements next to it, except when ordered otherwise (by adding a float declaration to another element, for instance).

display: inline means that the element is displayed inline, inside the current block on the same line. Only when it's between two blocks does the element form an 'anonymous block', that however has the smallest possible width.

Read more about display options : http://www.quirksmode.org/css/display.html

You can try this solution :-

To have mysql asking you for a password, you also need to specify the -p-option: (try with space between -p and password)

mysql -u root -p new_password

Come on guys, there is no need to loop, just use simple math to solve this equation system:

a*b = i;

a+b = j;

a = j/b;

a = i-b;

j/b = i-b; so:

b + j/b + i = 0

b^2 + i*b + j = 0

From here, its a quadratic equation, and it's trivial to find b (just implement the quadratic equation formula) and from there get the value for a.

EDIT:

There you go:

function finder($add,$product)
{

 $inside_root = $add*$add - 4*$product;

 if($inside_root >=0)
 {

     $b = ($add + sqrt($inside_root))/2;
     $a = $add - $b;

     echo "$a+$b = $add and $a*$b=$product\n";

 }else
 {
   echo "No real solution\n";
 }
}

I couldn't figure out what exactly you meant by byte String, but here are some conversions from byte to String and vice versa, of course there is a lot more on the official documentations

Integer intValue = 149;

The corresponding byte value is:

Byte byteValue = intValue.byteValue(); // this will convert the rightmost byte of the intValue to byte, because Byte is an 8 bit object and Integer is at least 16 bit, and it will give you a signed number in this case -107

get the integer value back from a Byte variable:

Integer anInt = byteValue.intValue(); // This will convert the byteValue variable to a signed Integer

From Byte and Integer to hex String:
This is the way I do it:

Integer anInt = 149
Byte aByte = anInt.byteValue();

String hexFromInt = "".format("0x%x", anInt); // This will output 0x95
String hexFromByte = "".format("0x%x", aByte); // This will output 0x95

Converting an array of bytes to a hex string:
As far as I know there is no simple function to convert all the elements inside an array of some Object to elements of another Object, So you have to do it yourself. You can use the following functions:

From byte[] to String:

    public static String byteArrayToHexString(byte[] byteArray){
        String hexString = "";

        for(int i = 0; i < byteArray.length; i++){
            String thisByte = "".format("%x", byteArray[i]);
            hexString += thisByte;
        }

        return hexString;
    }

And from hex string to byte[]:

public static byte[] hexStringToByteArray(String hexString){
    byte[] bytes = new byte[hexString.length() / 2];

    for(int i = 0; i < hexString.length(); i += 2){
        String sub = hexString.substring(i, i + 2);
        Integer intVal = Integer.parseInt(sub, 16);
        bytes[i / 2] = intVal.byteValue();
        String hex = "".format("0x%x", bytes[i / 2]);
    }

    return bytes;
}  

It is too late but I hope this could help some others ;)

How do you change your cursor to the finger (like for clicking on links) instead of the regular pointer?

This is very simple to achieve using the CSS property cursor, no jQuery needed.

You can read more about in: CSS cursor property and cursor - CSS | MDN

.default {_x000D_
  cursor: default;_x000D_
}_x000D_
.pointer {_x000D_
  cursor: pointer;_x000D_
}

<a class="default" href="#">default</a>_x000D_
_x000D_
<a class="pointer" href="#">pointer</a>

It is now possible to specify local Node module installation paths in your package.json directly. From the docs:

Local Paths

As of version 2.0.0 you can provide a path to a local directory that contains a package. Local paths can be saved using npm install -S or npm install --save, using any of these forms:

../foo/bar
~/foo/bar
./foo/bar
/foo/bar

in which case they will be normalized to a relative path and added to your package.json. For example:

{
  "name": "baz",
  "dependencies": {
    "bar": "file:../foo/bar"
  }
}

This feature is helpful for local offline development and creating tests that require npm installing where you don't want to hit an external server, but should not be used when publishing packages to the public registry.

You can also try adding the Motumedia PPA to your apt sources and update your ffmpeg packages.

Short Answer

To make a clean install of Python 3.6.5 use:

brew unlink python # ONLY if you have installed (with brew) another version of python 3
brew install --ignore-dependencies https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb

If you prefer to recover a previously installed version, then:

brew info python           # To see what you have previously installed
brew switch python 3.x.x_x # Ex. 3.6.5_1

Long Answer

There are two formulas for installing Python with Homebrew: python@2 and python.
The first is for Python 2 and the second for Python 3.

Note: You can find outdated answers on the web where it is mentioned python3 as the formula name for installing Python version 3. Now it's just python!

By default, with these formulas you can install the latest version of the corresponding major version of Python. So, you cannot directly install a minor version like 3.6.

Solution

With brew, you can install a package using the address of the formula, for example in a git repository.

brew install https://the/address/to/the/formula/FORMULA_NAME.rb

Or specifically for Python 3

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/COMMIT_IDENTIFIER/Formula/python.rb

The address you must specify is the address to the last commit of the formula (python.rb) for the desired version. You can find the commint identifier by looking at the history for homebrew-core/Formula/python.rb

https://github.com/Homebrew/homebrew-core/commits/master/Formula/python.rb

Python > 3.6.5

In the link above you will not find a formula for a version of Python above 3.6.5. After the maintainers of that (official) repository released Python 3.7, they only submit updates to the recipe of Python 3.7.

As explained above, with homebrew you have only Python 2 (python@2) and Python 3 (python), there is no explicit formula for Python 3.6.

Although those minor updates are mostly irrelevant in most cases and for most users, I will search if someone has done an explicit formula for 3.6.

You can use CURL for this purpose see the example code:

$url = "your url";    
$content = json_encode("your data to be sent");

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
        array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 201 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}


curl_close($curl);

$response = json_decode($json_response, true);

The most likely explanation is that either a file called 'pandas.py' is in the same directory as your script, or that another variable called 'pd' is used in your program.
