An Assert is to check -
1. the valid condition,
2. the valid statement,
3. true logic;
of source code. Instead of failing the whole project it gives an alarm that something is not appropriate in your source file.

In example 1, since variable 'str' is not null. So no any assert or exception get raised.

Example 1:

#!/usr/bin/python

str = 'hello Python!'
strNull = 'string is Null'

if __debug__:
    if not str: raise AssertionError(strNull)
print str

if __debug__:
    print 'FileName '.ljust(30,'.'),(__name__)
    print 'FilePath '.ljust(30,'.'),(__file__)


------------------------------------------------------

Output:
hello Python!
FileName ..................... hello
FilePath ..................... C:/Python\hello.py

In example 2, var 'str' is null. So we are saving the user from going ahead of faulty program by assert statement.

Example 2:

#!/usr/bin/python

str = ''
strNull = 'NULL String'

if __debug__:
    if not str: raise AssertionError(strNull)
print str

if __debug__:
    print 'FileName '.ljust(30,'.'),(__name__)
    print 'FilePath '.ljust(30,'.'),(__file__)


------------------------------------------------------

Output:
AssertionError: NULL String

The moment we don't want debug and realized the assertion issue in the source code. Disable the optimization flag

python -O assertStatement.py
nothing will get print

It has 2 purposes.

yentup has given the first one.

It's used for raising your own errors.

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

The second is to reraise the current exception in an exception handler, so that it can be handled further up the call stack.

try:
  generate_exception()
except SomeException as e:
  if not can_handle(e):
    raise
  handle_exception(e)

i use colname(train) = paste("A", colname(train)) and it turns out to the same problem as yours.

I finally figure out that randomForest is more stingy than rpart, it can't recognize the colname with space, comma or other specific punctuation.

paste function will prepend "A" and " " as seperator with each colname. so we need to avert the space and use this sentence instead:

colname(train) = paste("A", colname(train), sep = "")

this will prepend string without space.

Sorry this is and old thread but some people would still need this I guess,

Note: I achieved this using Animate.css library for animating the fade.

I used your code and just added .hidden class (using bootstrap's hidden class) but you can still just define .hidden { opacity: 0; }

$(document).ready(function() {

/* Every time the window is scrolled ... */

$(window).scroll( function(){

/* Check the location of each desired element */
$('.hideme').each( function(i){

    var bottom_of_object = $(this).position().top + $(this).outerHeight();
    var bottom_of_window = $(window).scrollTop() + $(window).height();


    /* If the object is completely visible in the window, fade it it */
    if( bottom_of_window > bottom_of_object ){

        $(this).removeClass('hidden');
        $(this).addClass('animated fadeInUp');
    }    else {
            $(this).addClass('hidden');
               }

}); 
}); 
});

Another Note: Applying this to containers might cause it to be glitchy.

Very Simple Just go to Tools->Firebase->Connect to firebase than click on sync now THIS WILL SURELY WORK.

Jsmn is quite minimalistic and has only two functions to work with.

https://github.com/zserge/jsmn

I have almost exactly the same code as you and mine works.

Do you have jQueryUI.js included in the page?

There's a fiddle here

<input type="text" ng-model="date" jqdatepicker />
<br/>
{{ date }}


var datePicker = angular.module('app', []);

datePicker.directive('jqdatepicker', function () {
    return {
        restrict: 'A',
        require: 'ngModel',
         link: function (scope, element, attrs, ngModelCtrl) {
            element.datepicker({
                dateFormat: 'DD, d  MM, yy',
                onSelect: function (date) {
                    scope.date = date;
                    scope.$apply();
                }
            });
        }
    };
});

You'll also need the ng-app="app" somewhere in your HTML

July 25, 2019 :

I was facing this issue in Android Studio 3.0.1 :

After checking lots of posts, here is Fix which works:

Go to module build.gradle and within Android block add this script:

splits {
    abi {
        enable true
        reset()
        include 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a'
        universalApk true
    }
}

Simple Solution. Feel free to comment. Thanks.

If you are using non-parallel direct path loads then consider and benchmark not dropping the indexes at all, particularly if the indexes only cover a minority of the columns. Oracle has a mechanism for efficient maintenance of indexes on direct path loads.

Otherwise, I'd also advise making the indexes unusable instead of dropping them. Less chance of accidentally not recreating an index.

Values known at compile time can (and in my opinion should) be marked as constant.

Naming conventions should follow Java ones and should be properly visible when used from Java code (it's somehow hard to achieve with companion objects, but anyway).

The proper constant declarations are:

const val MY_CONST = "something"
const val MY_INT = 1

tl;dr takeaway:

If you're looking for a very high standard for yourself or team, JSLint. But its not necessarily THE standard, just A standard, some of which comes to us dogmatically from a javascript god named Doug Crockford. If you want to be a bit more flexible, or have some old pros on your team that don't buy into JSLint's opinions, or are going back and forth between JS and other C-family languages on a regular basis, try JSHint.

long version:

The reasoning behind the fork explains pretty well why JSHint exists:

http://badassjs.com/post/3364925033/jshint-an-community-driven-fork-of-jslint http://anton.kovalyov.net/2011/02/20/why-i-forked-jslint-to-jshint/

So I guess the idea is that it's "community-driven" rather than Crockford-driven. In practicality, JSHint is generally a bit more lenient (or at least configurable or agnostic) on a few stylistic and minor syntactical "opinions" that JSLint is a stickler on.

As an example, if you think both the A and B below are fine, or if you want to write code with one or more of the aspects of A that aren't available in B, JSHint is for you. If you think B is the only correct option... JSLint. I'm sure there are other differences, but this highlights a few.

A) Passes JSHint out of the box - fails JSLint

(function() {
  "use strict";
  var x=0, y=2;
  function add(val1, val2){
    return val1 + val2;
  }
  var z;
  for (var i=0; i<2; i++){
    z = add(y, x+i);
  }
})();

B) Passes Both JSHint and JSLint

(function () {
    "use strict";
    var x = 0, y = 2, i, z;
    function add(val1, val2) {
       return val1 + val2;
    }
    for (i = 0; i < 2; i += 1) {
        z = add(y, x + i);
    }
}());

Personally I find JSLint code very nice to look at, and the only hard features of it that I disagree with are its hatred of more than one var declaration in a function and of for-loop var i = 0 declarations, and some of the whitespace enforcements for function declarations.

A few of the whitespace things that JSLint enforces, I find to be not necessarily bad, but out of sync with some pretty standard whitespace conventions for other languages in the family (C, Java, Python, etc...), which are often followed as conventions in Javascript as well. Since I'm writing in various of these languages throughout the day, and working with team members who don't like Lint-style whitespace in our code, I find JSHint to be a good balance. It catches stuff that's a legitimate bug or really bad form, but doesn't bark at me like JSLint does (sometimes, in ways I can't disable) for the stylistic opinions or syntactic nitpicks that I don't care for.

A lot of good libraries aren't Lint'able, which to me demonstrates that there's some truth to the idea that some of JSLint is simply just about pushing 1 version of "good code" (which is, indeed, good code). But then again, the same libraries (or other good ones) probably aren't Hint'able either, so, touché.

Can em.flush() cause any harm when using it within a transaction?

Yes, it may hold locks in the database for a longer duration than necessary.

Generally, When using JPA you delegates the transaction management to the container (a.k.a CMT - using @Transactional annotation on business methods) which means that a transaction is automatically started when entering the method and commited / rolled back at the end. If you let the EntityManager handle the database synchronization, sql statements execution will be only triggered just before the commit, leading to short lived locks in database. Otherwise your manually flushed write operations may retain locks between the manual flush and the automatic commit which can be long according to remaining method execution time.

Notes that some operation automatically triggers a flush : executing a native query against the same session (EM state must be flushed to be reachable by the SQL query), inserting entities using native generated id (generated by the database, so the insert statement must be triggered thus the EM is able to retrieve the generated id and properly manage relationships)

FractionallySizedBox may also be useful. You can also read the screen width directly out of MediaQuery.of(context).size and create a sized box based on that

MediaQuery.of(context).size.width * 0.65

if you really want to size as a fraction of the screen regardless of what the layout is.

Reference the System.Web dll in your model and use System.Web.Caching.Cache

    public string[] GetNames()
    {
      string[] names = Cache["names"] as string[];
      if(names == null) //not in cache
      {
        names = DB.GetNames();
        Cache["names"] = names;
      }
      return names;
    }

A bit simplified but I guess that would work. This is not MVC specific and I have always used this method for caching data.

In Java, static methods belong to the class rather than the instance. This means that you cannot call other instance methods from static methods unless they are called in an instance that you have initialized in that method.

Here's something you might want to do:

public class Foo
{
  public void fee()
  {
     //do stuff  
  }

  public static void main (String[]arg) 
  { 
     Foo foo = new Foo();
     foo.fee();
  } 
}

Notice that you are running an instance method from an instance that you've instantiated. You can't just call call a class instance method directly from a static method because there is no instance related to that static method.

I considered with timezone in my Google Docs like this:

timezone = "GMT+" + new Date().getTimezoneOffset()/60
var date = Utilities.formatDate(new Date(), timezone, "yyyy-MM-dd HH:mm"); // "yyyy-MM-dd'T'HH:mm:ss'Z'"

my script for Google docs

By using pg_restore command you can restore postgres database

First open terminal type

sudo su postgres

Create new database

createdb [database name] -O [owner]

createdb test_db [-O openerp]

pg_restore -d [Database Name] [path of dump file]

pg_restore -d test_db /home/sagar/Download/sample_dbump

Wait for completion of database restoring.

Remember that dump file should have read, write, execute access, so for that you can apply chmod command

I had the same error message but for a totally different reason.

Being new to docker, I issued

docker run -it <crypticalId>

where <crypticalId> was the id of my newly created container.

But, the run command wants the id of an image, not a container.

To start a container, docker wants

docker start -i <crypticalId>

To compare date only with year - month - day and without time for me worked like this:

     let order = Calendar.current.compare(self.startDate, to: compareDate!, toGranularity: .day)  

                      switch order {
                        case .orderedAscending:
                            print("\(gpsDate) is after \(self.startDate)")
                        case .orderedDescending:
                            print("\(gpsDate) is before \(self.startDate)")
                        default:
                            print("\(gpsDate) is the same as \(self.startDate)")
                        }

This works on my Mac OS:

for n in `ipcs -b -m | egrep ^m | awk '{ print $2; }'`; do ipcrm -m $n; done

Valid for API16 to API28 Just place this method some where:

Context newContext = context;

Locale locale = new Locale(languageCode);
Locale.setDefault(locale);

Resources resources = context.getResources();
Configuration config = new Configuration(resources.getConfiguration());

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
    config.setLocale(locale);
    newContext = context.createConfigurationContext(config);
} else {
    config.locale = locale;
    resources.updateConfiguration(config, resources.getDisplayMetrics());
}

return newContext;

Insert this code in all your activitys using:

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(localeUpdateResources(base, "<-- language code -->"));
    }

or call localeUpdateResources on fragments, adapters, etc. where you need the new context.

One way to control your DialogFragment's width and height is to make sure its dialog respects your view's width and height if their value is WRAP_CONTENT.

Using ThemeOverlay.AppCompat.Dialog

One simple way to achieve this is to make use of the ThemeOverlay.AppCompat.Dialog style that's included in Android Support Library.

DialogFragment with Dialog:

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = LayoutInflater.from(getContext());
    View view = inflater.inflate(R.layout.dialog_view, null);

    Dialog dialog = new Dialog(getContext(), R.style.ThemeOverlay_AppCompat_Dialog);
    dialog.setContentView(view);
    return dialog;
}

DialogFragment with AlertDialog (caveat: minHeight="48dp"):

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = LayoutInflater.from(getContext());
    View view = inflater.inflate(R.layout.dialog_view, null);

    AlertDialog.Builder builder = new AlertDialog.Builder(getContext(), R.style.ThemeOverlay_AppCompat_Dialog);
    builder.setView(view);
    return builder.create();
}

You can also set ThemeOverlay.AppCompat.Dialog as the default theme when creating your dialogs, by adding it to your app's xml theme.
Be careful, as many dialogs do need the default minimum width to look good.

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- For Android Dialog. -->
    <item name="android:dialogTheme">@style/ThemeOverlay.AppCompat.Dialog</item>

    <!-- For Android AlertDialog. -->
    <item name="android:alertDialogTheme">@style/ThemeOverlay.AppCompat.Dialog</item>

    <!-- For AppCompat AlertDialog. -->
    <item name="alertDialogTheme">@style/ThemeOverlay.AppCompat.Dialog</item>

    <!-- Other attributes. -->
</style>

DialogFragment with Dialog, making use of android:dialogTheme:

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = LayoutInflater.from(getContext());
    View view = inflater.inflate(R.layout.dialog_view, null);

    Dialog dialog = new Dialog(getContext());
    dialog.setContentView(view);
    return dialog;
}

DialogFragment with AlertDialog, making use of android:alertDialogTheme or alertDialogTheme (caveat: minHeight="48dp"):

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = LayoutInflater.from(getContext());
    View view = inflater.inflate(R.layout.dialog_view, null);

    AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
    builder.setView(view);
    return builder.create();
}

Bonus

On Older Android APIs, Dialogs seem to have some width issues, because of their title (even if you don't set one).
If you don't want to use ThemeOverlay.AppCompat.Dialog style and your Dialog doesn't need a title (or has a custom one), you might want to disable it:

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = LayoutInflater.from(getContext());
    View view = inflater.inflate(R.layout.dialog_view, null);

    Dialog dialog = new Dialog(getContext());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(view);
    return dialog;
}

Outdated answer, won't work in most cases

_{I was trying to make the dialog respect the width and height of my layout, without specifying a fixed size programmatically.}

_{I figured that android:windowMinWidthMinor and android:windowMinWidthMajor were causing the problem. Even though they were not included in the theme of my Activity or Dialog, they were still being applied to the Activity theme, somehow.}

_{I came up with three possible solutions.}

_{Solution 1: create a custom dialog theme and use it when creating the dialog in the DialogFragment.}

<style name="Theme.Material.Light.Dialog.NoMinWidth" parent="android:Theme.Material.Light.Dialog">
    <item name="android:windowMinWidthMinor">0dip</item>
    <item name="android:windowMinWidthMajor">0dip</item>
</style>

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new Dialog(getActivity(), R.style.Theme_Material_Light_Dialog_NoMinWidth);
}

_{Solution 2: create a custom theme to be used in a ContextThemeWrapper that will serve as Context for the dialog. Use this if you don't want to create a custom dialog theme (for instance, when you want to use the theme specified by android:dialogTheme).}

<style name="Theme.Window.NoMinWidth" parent="">
    <item name="android:windowMinWidthMinor">0dip</item>
    <item name="android:windowMinWidthMajor">0dip</item>
</style>

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new Dialog(new ContextThemeWrapper(getActivity(), R.style.Theme_Window_NoMinWidth), getTheme());
}

_{Solution 3 (with an AlertDialog): enforce android:windowMinWidthMinor and android:windowMinWidthMajor into the ContextThemeWrapper created by the AlertDialog$Builder.}

<style name="Theme.Window.NoMinWidth" parent="">
    <item name="android:windowMinWidthMinor">0dip</item>
    <item name="android:windowMinWidthMajor">0dip</item>
</style>

@Override
public final Dialog onCreateDialog(Bundle savedInstanceState) {
    View view = new View(); // Inflate your view here.
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setView(view);
    // Make sure the dialog width works as WRAP_CONTENT.
    builder.getContext().getTheme().applyStyle(R.style.Theme_Window_NoMinWidth, true);
    return builder.create();
}

Of course you can use multiple versions of Java under Windows. And different applications can use different Java versions. How is your application started? Usually you will have a batch file where there is something like

java ...

This will search the Java executable using the PATH variable. So if Java 5 is first on the PATH, you will have problems running a Java 6 application. You should then modify the batch file to use a certain Java version e.g. by defining a environment variable JAVA6HOME with the value C:\java\java6 (if Java 6 is installed in this directory) and change the batch file calling

%JAVA6HOME%\bin\java ...

Well, I'm not sure to understand your question...

In C, Char[] and Char* are the same thing.

Edit : thanks for this interesting link.

Let's understand in simple words

• PRI - It's a primary key, and used to identify records uniquely.
• UNI - It's a unique key, and also used to identify records uniquely. It looks similar like primary key but a table can have multiple unique keys and unique key can have one null value, on the other hand table can have only one primary key and can't store null as a primary key.
• MUL - It's doesn't have unique constraint and table can have multiple MUL columns.

Note: These keys have more depth as a concept but this is good to start.

Use the following:

type file.txt | findstr /v ERROR | findstr /v REFERENCE

This has the advantage of using standard tools in the Windows OS, rather than having to find and install sed/awk/perl and such.

See the following transcript for it in operation:

C:\>type file.txt
Good Line of data
bad line of C:\Directory\ERROR\myFile.dll
Another good line of data
bad line: REFERENCE
Good line

C:\>type file.txt | findstr /v ERROR | findstr /v REFERENCE
Good Line of data
Another good line of data
Good line

Updated for pandas 0.20 given that ix is deprecated. This demonstrates not only how to use loc, iloc, at, iat, set_value, but how to accomplish, mixed positional/label based indexing.

loc - label based
Allows you to pass 1-D arrays as indexers. Arrays can be either slices (subsets) of the index or column, or they can be boolean arrays which are equal in length to the index or columns.

Special Note: when a scalar indexer is passed, loc can assign a new index or column value that didn't exist before.

# label based, but we can use position values
# to get the labels from the index object
df.loc[df.index[2], 'ColName'] = 3

df.loc[df.index[1:3], 'ColName'] = 3

iloc - position based
Similar to loc except with positions rather that index values. However, you cannot assign new columns or indices.

# position based, but we can get the position
# from the columns object via the `get_loc` method
df.iloc[2, df.columns.get_loc('ColName')] = 3

df.iloc[2, 4] = 3

df.iloc[:3, 2:4] = 3

at - label based
Works very similar to loc for scalar indexers. Cannot operate on array indexers. Can! assign new indices and columns.

Advantage over loc is that this is faster.
Disadvantage is that you can't use arrays for indexers.

# label based, but we can use position values
# to get the labels from the index object
df.at[df.index[2], 'ColName'] = 3

df.at['C', 'ColName'] = 3

iat - position based
Works similarly to iloc. Cannot work in array indexers. Cannot! assign new indices and columns.

Advantage over iloc is that this is faster.
Disadvantage is that you can't use arrays for indexers.

# position based, but we can get the position
# from the columns object via the `get_loc` method
IBM.iat[2, IBM.columns.get_loc('PNL')] = 3

set_value - label based
Works very similar to loc for scalar indexers. Cannot operate on array indexers. Can! assign new indices and columns

Advantage Super fast, because there is very little overhead!
Disadvantage There is very little overhead because pandas is not doing a bunch of safety checks. Use at your own risk. Also, this is not intended for public use.

# label based, but we can use position values
# to get the labels from the index object
df.set_value(df.index[2], 'ColName', 3)

set_value with takable=True - position based
Works similarly to iloc. Cannot work in array indexers. Cannot! assign new indices and columns.

Advantage Super fast, because there is very little overhead!
Disadvantage There is very little overhead because pandas is not doing a bunch of safety checks. Use at your own risk. Also, this is not intended for public use.

# position based, but we can get the position
# from the columns object via the `get_loc` method
df.set_value(2, df.columns.get_loc('ColName'), 3, takable=True)

You probably don't want to just declare routes_list as an object type. It doesn't have a .test property, so you really aren't going to get a nice object back. This is one of those places where you would be better off defining a class or a struct, or make use of the dynamic keyword.

If you really want this code to work as you have it, you'll need to know that the object returned by DeserializeObject is a generic dictionary of string,object. Here's the code to do it that way:

var json_serializer = new JavaScriptSerializer();
var routes_list = (IDictionary<string, object>)json_serializer.DeserializeObject("{ \"test\":\"some data\" }");
Console.WriteLine(routes_list["test"]);

If you want to use the dynamic keyword, you can read how here.

If you declare a class or struct, you can call Deserialize instead of DeserializeObject like so:

class MyProgram {
    struct MyObj {
        public string test { get; set; }
    }

    static void Main(string[] args) {
        var json_serializer = new JavaScriptSerializer();
        MyObj routes_list = json_serializer.Deserialize<MyObj>("{ \"test\":\"some data\" }");
        Console.WriteLine(routes_list.test);

        Console.WriteLine("Done...");
        Console.ReadKey(true);
    }
}

@RestController was provided since Spring 4.0.1. These controllers indicate that here @RequestMapping methods assume @ResponseBody semantics by default.

In earlier versions the similar functionality could be achieved by using below:

1. @RequestMapping coupled with @ResponseBody like @RequestMapping(value = "/abc", method = RequestMethod.GET, produces ="application/xml") public @ResponseBody MyBean fetch(){ return new MyBean("hi") }

2. <mvc:annotation-driven/> may be used as one of the ways for using JSON with Jackson or xml.

3. MyBean can be defined like

@XmlRootElement(name = "MyBean") @XmlType(propOrder = {"field2", "field1"}) public class MyBean{ field1 field2 .. //getter, setter }

4. @ResponseBody is treated as the view here among MVC and it is dispatched directly instead being dispatched from Dispatcher Servlet and the respective converters convert the response in the related format like text/html, application/xml, application/json .

However, the Restcontroller is already coupled with ResponseBody and the respective converters. Secondly, here, since instead of converting the responsebody, it is automatically converted to http response.

window.location.hash is a string, so do this:

var page_number: number = 3;
window.location.hash = String(page_number); 

If you don't do anything in your bash script than run the php one, you could simply run the php script from cron with a command like /usr/bin/php /path/to/your/file.php.

You can get deadlocks on more than just row locks, e.g. see this. The scripts may be competing for other resources, such as index blocks.

I've gotten around this in the past by engineering the parallelism in such a way that different instances are working on portions of the workload that are less likely to affect blocks that are close to each other; for example, for an update of a large table, instead of setting up the parallel slaves using something like MOD(n,10), I'd use TRUNC(n/10) which mean that each slave worked on a contiguous set of data.

There are, of course, much better ways of splitting up a job for parallelism, e.g. DBMS_PARALLEL_EXECUTE.

Not sure why you're getting "PL/SQL successfully completed", perhaps your scripts are handling the exception?

This will work:

if (val) {
    alert("Not null");
} else {
    alert("Null");
}

So building on @zzzeek's comments on @bukzor's code I came up with this to easily get a "pretty-printable" query:

def prettyprintable(statement, dialect=None, reindent=True):
    """Generate an SQL expression string with bound parameters rendered inline
    for the given SQLAlchemy statement. The function can also receive a
    `sqlalchemy.orm.Query` object instead of statement.
    can 

    WARNING: Should only be used for debugging. Inlining parameters is not
             safe when handling user created data.
    """
    import sqlparse
    import sqlalchemy.orm
    if isinstance(statement, sqlalchemy.orm.Query):
        if dialect is None:
            dialect = statement.session.get_bind().dialect
        statement = statement.statement
    compiled = statement.compile(dialect=dialect,
                                 compile_kwargs={'literal_binds': True})
    return sqlparse.format(str(compiled), reindent=reindent)

I personally have a hard time reading code which is not indented so I've used sqlparse to reindent the SQL. It can be installed with pip install sqlparse.

There is no guarantee that your threads are executing simultaneously regardless of any trivial example anyone else posts. If your OS only gives the java process one processor to work on, your java threads will still be scheduled for each time slice in a round robin fashion. Meaning, no two will ever be executing simultaneously, but the work they do will be interleaved. You can use monitoring tools like Java's Visual VM (standard in the JDK) to observe the threads executing in a Java process.

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

You need to "clear" the float after every 6 images. So with your current code, change the styles for containerdivNewLine to:

.containerdivNewLine { clear: both; float: left; display: block; position: relative; } 

You don't. strings.xml is just here to define the raw text messages. You should (must) use styles.xml to define reusable visual styles to apply to your widgets.

Think of it as a good practice to separate the concerns. You can work on the visual styles independently from the text messages.

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

you mentioned "entire line" , so i assumed mystring is the entire line.

if "token" in mystring:
    print(mystring)

however if you want to just get "token qwerty",

>>> mystring="""
...     qwertyuiop
...     asdfghjkl
...
...     zxcvbnm
...     token qwerty
...
...     asdfghjklñ
... """
>>> for item in mystring.split("\n"):
...  if "token" in item:
...     print (item.strip())
...
token qwerty

I guess you want to read in, ignore the white space, and write it out again. Most XML packages have an option to ignore white space. For example, the DocumentBuilderFactory has setIgnoringElementContentWhitespace for this purpose.

Similarly if you are generating the XML by marshaling an object then JAXB has JAXB_FORMATTED_OUTPUT

You can make it with jQuery a less lines:

$(function(){

    var requiredCheckboxes = $(':checkbox[required]');

    requiredCheckboxes.change(function(){

        if(requiredCheckboxes.is(':checked')) {
            requiredCheckboxes.removeAttr('required');
        }

        else {
            requiredCheckboxes.attr('required', 'required');
        }
    });

});

With $(':checkbox[required]') you select all checkboxes with the attribute required, then, with the .change method applied to this group of checkboxes, you can execute the function you want when any item of this group changes. In this case, if any of the checkboxes is checked, I remove the required attribute for all of the checkboxes that are part of the selected group.

I hope this helps.

Farewell.

For a side-by-side visual representation, I use git difftool with openDiff set to the default viewer.

Example usage:

git difftool tags/<FIRST TAG> tags/<SECOND TAG>

If you are only interested in a specific file, you can use:

git difftool tags/<FIRST TAG>:<FILE PATH> tags/<SECOND TAG>:<FILE PATH>

As a side-note, the tags/<TAG>s can be replaced with <BRANCH>es if you are interested in diffing branches.

string GetString(RichTextBox rtb)
{
    var textRange = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd);
    return textRange.Text;
}

Bit less elegant but can also do:

sl[len(sl)-1: len(sl)]

if you are creating one object and adding it to the list that you use in your adapter , when you change one element of your list in the adapter all of your other items change too in other words its all about references and your list doesn't hold separate copies of that single object.

These are the main factors involved:

1. member variable (default OK)
2. static variable (default OK)
3. final member variable (not initialized, must set on constructor)
4. final static variable (not initialized, must set on a static block {})
5. local variable (not initialized)

Note 1: you must initialize final member variables on every implemented constructor!

Note 2: you must initialize final member variables inside the block of the constructor itself, not calling another method that initializes them. For instance, this is not valid:

private final int memberVar;

public Foo() {
    // Invalid initialization of a final member
    init();
}

private void init() {
    memberVar = 10;
}

Note 3: arrays are Objects in Java, even if they store primitives.

Note 4: when you initialize an array, all of its items are set to default, independently of being a member or a local array.

I am attaching a code example, presenting the aforementioned cases:

public class Foo {
    // Static and member variables are initialized to default values

    // Primitives
    private int a; // Default 0
    private static int b; // Default 0

    // Objects
    private Object c; // Default NULL
    private static Object d; // Default NULL

    // Arrays (note: they are objects too, even if they store primitives)
    private int[] e; // Default NULL
    private static int[] f; // Default NULL

    // What if declared as final?

    // Primitives
    private final int g; // Not initialized. MUST set in the constructor
    private final static int h; // Not initialized. MUST set in a static {}

    // Objects
    private final Object i; // Not initialized. MUST set in constructor
    private final static Object j; // Not initialized. MUST set in a static {}

    // Arrays
    private final int[] k; // Not initialized. MUST set in constructor
    private final static int[] l; // Not initialized. MUST set in a static {}

    // Initialize final statics
    static {
        h = 5;
        j = new Object();
        l = new int[5]; // Elements of l are initialized to 0
    }

    // Initialize final member variables
    public Foo() {
        g = 10;
        i = new Object();
        k = new int[10]; // Elements of k are initialized to 0
    }

    // A second example constructor
    // You have to initialize final member variables to every constructor!
    public Foo(boolean aBoolean) {
        g = 15;
        i = new Object();
        k = new int[15]; // Elements of k are initialized to 0
    }

    public static void main(String[] args) {
        // Local variables are not initialized
        int m; // Not initialized
        Object n; // Not initialized
        int[] o; // Not initialized

        // We must initialize them before use
        m = 20;
        n = new Object();
        o = new int[20]; // Elements of o are initialized to 0
    }
}

The documentation makes indeed a difference between the purpose

An informative annotation type used to indicate that an interface type declaration is intended to be a functional interface as defined by the Java Language Specification.

and the use case

Note that instances of functional interfaces can be created with lambda expressions, method references, or constructor references.

whose wording does not preclude other use cases in general. Since the primary purpose is to indicate a functional interface, your actual question boils down to “Are there other use cases for functional interfaces other than lambda expressions and method/constructor references?”

Since functional interface is a Java language construct defined by the Java Language Specification, only that specification can answer that question:

JLS §9.8. Functional Interfaces:

…

In addition to the usual process of creating an interface instance by declaring and instantiating a class (§15.9), instances of functional interfaces can be created with method reference expressions and lambda expressions (§15.13, §15.27).

So the Java Language Specification doesn’t say otherwise, the only use case mentioned in that section is that of creating interface instances with method reference expressions and lambda expressions. (This includes constructor references as they are noted as one form of method reference expression in the specification).

So in one sentence, no, there is no other use case for it in Java 8.

It depends what is the character and what encoding it is in:

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

• An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

• A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

• A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

• A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

• An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

• The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

That would mean that there are between 0.03125 and 0.125 characters in a bit.

The function that I use to find the length of the string is length, used as follows:

SELECT * FROM table ORDER BY length(column);

I found this.

String newString = string.replaceAll("\n", " ");

Although, as you have a double line, you will get a double space. I guess you could then do another replace all to replace double spaces with a single one.

If that doesn't work try doing:

string.replaceAll(System.getProperty("line.separator"), " ");

If I create lines in "string" by using "\n" I had to use "\n" in the regex. If I used System.getProperty() I had to use that.

Lambas might be a solution

Integer[] nums =  new Integer[] {1, 1, 2, 3, 3, 3};
List<Integer> list = Arrays.asList(nums);

List<Integer> dps = list.stream().distinct().filter(entry -> Collections.frequency(list, entry) > 1).collect(Collectors.toList());

ST2 has a feature for changing multiple selections at once.

1. Double click the first instance of 0 that you want to change.
2. Press the key for Find->Quick Add Next* to select the next instance of 0, and repeat until you've selected all the instances of 0 that you want to change.
   If this method selects an instance that you want to skip, press the key for Find->Quick Skip Next.
3. Verify that the multiple highlighted fields are what you want to replace. Next, type in '255' and it should modify all of the selected instances simultaneously.

*Look at the Find menu on the menu bar to find the correct shortcut key for your system. For vanilla Windows, the menu tells you that Find->Quick Add Next is Ctrl+D and Find->Quick Skip Next is Ctrl+K,Ctrl+D.

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

placement_by_video_summary = placement_by_video_summary.drop(placement_by_video_summary_new.index)
                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

You can use the Java enum TimeUnit to perform your math and avoid any hard coded values. Then we can use String.format(String, Object...) and a pair of StringBuilder(s) as well as a DecimalFormat to build the requested output. Something like,

Scanner scanner = new Scanner(System.in);
System.out.println("Please enter a number of seconds:");
String str = scanner.nextLine().replace("\\,", "").trim();
long secondsIn = Long.parseLong(str);
long dayCount = TimeUnit.SECONDS.toDays(secondsIn);
long secondsCount = secondsIn - TimeUnit.DAYS.toSeconds(dayCount);
long hourCount = TimeUnit.SECONDS.toHours(secondsCount);
secondsCount -= TimeUnit.HOURS.toSeconds(hourCount);
long minutesCount = TimeUnit.SECONDS.toMinutes(secondsCount);
secondsCount -= TimeUnit.MINUTES.toSeconds(minutesCount);
StringBuilder sb = new StringBuilder();
sb.append(String.format("%d %s, ", dayCount, (dayCount == 1) ? "day"
        : "days"));
StringBuilder sb2 = new StringBuilder();
sb2.append(sb.toString());
sb2.append(String.format("%02d:%02d:%02d %s", hourCount, minutesCount,
        secondsCount, (hourCount == 1) ? "hour" : "hours"));
sb.append(String.format("%d %s, ", hourCount, (hourCount == 1) ? "hour"
        : "hours"));
sb.append(String.format("%d %s and ", minutesCount,
        (minutesCount == 1) ? "minute" : "minutes"));
sb.append(String.format("%d %s.", secondsCount,
        (secondsCount == 1) ? "second" : "seconds"));
System.out.printf("You entered %s seconds, which is %s (%s)%n",
        new DecimalFormat("#,###").format(secondsIn), sb, sb2);

Which, when I enter 500000 outputs the requested (manual line break added for post) -

You entered 500,000 seconds, which is 5 days, 18 hours, 
53 minutes and 20 seconds. (5 days, 18:53:20 hours)

No browsers currently have the code necessary to render Word Documents, and as far as I know, there are no client-side libraries that currently exist for rendering them either.

However, if you only need to display the Word Document, but don't need to edit it, you can use Google Documents' Viewer via an <iframe> to display a remotely hosted .doc/.docx.

<iframe src="https://docs.google.com/gview?url=http://remote.url.tld/path/to/document.doc&embedded=true"></iframe>

Solution adapted from "How to display a word document using fancybox".

Example:

JSFiddle

However, if you'd rather have native support, in most, if not all browsers, I'd recommend resaving the .doc/.docx as a PDF file Those can also be independently rendered using PDF.js by Mozilla.

Edit:

Huge thanks to fatbotdesigns for posting the Microsoft Office 365 viewer in the comments.

One more important caveat to keep in mind, as pointed out by lightswitch05, is that this will upload your document to a third-party server. If this is unacceptable, then this method of display isn't the proper course of action.

Update

You can now use select with the where selection helper. select_if is superceded, but still functional as of dplyr 1.0.2. (thanks to @mcstrother for bringing this to attention).

library(dplyr)
temp <- data.frame(x = 1:5, y = c(1,2,NA,4, 5), z = rep(NA, 5))
not_all_na <- function(x) any(!is.na(x))
not_any_na <- function(x) all(!is.na(x))

> temp
  x  y  z
1 1  1 NA
2 2  2 NA
3 3 NA NA
4 4  4 NA
5 5  5 NA

> temp %>% select(where(not_all_na))
  x  y
1 1  1
2 2  2
3 3 NA
4 4  4
5 5  5

> temp %>% select(where(not_any_na))
  x
1 1
2 2
3 3
4 4
5 5

Old Answer

dplyr now has a select_if verb that may be helpful here:

> temp
  x  y  z
1 1  1 NA
2 2  2 NA
3 3 NA NA
4 4  4 NA
5 5  5 NA

> temp %>% select_if(not_all_na)

While Sam Saffron did great work on it, he still didn't provide recursive common table expression code for this problem. And for us who working with SQL Server 2008 R2 and not Denali, it's still fastest way to get running total, it's about 10 times faster than cursor on my work computer for 100000 rows, and it's also inline query.
So, here it is (I'm supposing that there's an ord column in the table and it's sequential number without gaps, for fast processing there also should be unique constraint on this number):

;with 
CTE_RunningTotal
as
(
    select T.ord, T.total, T.total as running_total
    from #t as T
    where T.ord = 0
    union all
    select T.ord, T.total, T.total + C.running_total as running_total
    from CTE_RunningTotal as C
        inner join #t as T on T.ord = C.ord + 1
)
select C.ord, C.total, C.running_total
from CTE_RunningTotal as C
option (maxrecursion 0)

update I also was curious about this update with variable or quirky update. So usually it works ok, but how we can be sure that it works every time? well, here's a little trick (found it here - http://www.sqlservercentral.com/Forums/Topic802558-203-21.aspx#bm981258) - you just check current and previous ord and use 1/0 assignment in case they are different from what you expecting:

declare @total int, @ord int

select @total = 0, @ord = -1

update #t set
    @total = @total + total,
    @ord = case when ord <> @ord + 1 then 1/0 else ord end,
    ------------------------
    running_total = @total

select * from #t

-- CPU 0, Reads 58, Duration 139

From what I've seen if you have proper clustered index/primary key on your table (in our case it would be index by ord_id) update will proceed in a linear way all the time (never encountered divide by zero). That said, it's up to you to decide if you want to use it in production code :)

update 2 I'm linking this answer, cause it includes some useful info about unreliability of the quirky update - nvarchar concatenation / index / nvarchar(max) inexplicable behavior.

If you paste the string in server-side into the html don't need to do nothing:

For plain java in jsp:

var jsonObj=<%=jsonStringInJavaServlet%>;

For jsp width struts:

var jsonObj=<s:property value="jsonStringInJavaServlet" escape="false" escapeHtml="false"/>;

You can use the following: File.exists()

OPTION 1: Add this line to ~/.zshrc:

export "PATH=$HOME/pear/bin:$PATH"

After that you need to run source ~/.zshrc in order your changes to take affect OR close this window and open a new one

OPTION 2: execute it inside the terminal console to add this path only to the current terminal window session. When you close the window/session, it will be lost.

You can also use numpy loadtxt like

from numpy import loadtxt
lines = loadtxt("filename.dat", comments="#", delimiter=",", unpack=False)

You can get the best of both worlds. It is possible to use ExternalProject to download the gtest source and then use add_subdirectory() to add it to your build. This has the following advantages:

• gtest is built as part of your main build, so it uses the same compiler flags, etc. and hence avoids problems like the ones described in the question.
• There's no need to add the gtest sources to your own source tree.

Used in the normal way, ExternalProject won't do the download and unpacking at configure time (i.e. when CMake is run), but you can get it to do so with just a little bit of work. I've written a blog post on how to do this which also includes a generalised implementation which works for any external project which uses CMake as its build system, not just gtest. You can find them here:

• https://crascit.com/2015/07/25/cmake-gtest/
• https://github.com/Crascit/DownloadProject

Update: This approach is now also part of the googletest documentation.

Jianxun's solution did the job for me but broke the y value indicator at the bottom left of the window.

I ended up using FuncFormatterinstead (and also stripped the uneccessary trailing zeroes as suggested here):

import pandas as pd
import numpy as np
from matplotlib.ticker import FuncFormatter

df = pd.DataFrame(np.random.randn(100,5))

ax = df.plot()
ax.yaxis.set_major_formatter(FuncFormatter(lambda y, _: '{:.0%}'.format(y))) 

Generally speaking I'd recommend using FuncFormatter for label formatting: it's reliable, and versatile.

import threading

def printit():
  threading.Timer(5.0, printit).start()
  print "Hello, World!"

printit()

# continue with the rest of your code

https://docs.python.org/3/library/threading.html#timer-objects

Its absolutely possible only when you set layer.masksToBounds = true and do you rest stuff.

If you want the entire command line of your java process, you can use: JvmArguments.java (uses a combination of JNA + /proc to cover most unix implementations)

HttpContext.Current returns an instance of System.Web.HttpContext, which does not extend System.Web.HttpContextBase. HttpContextBase was added later to address HttpContext being difficult to mock. The two classes are basically unrelated (HttpContextWrapper is used as an adapter between them).

Fortunately, HttpContext itself is fakeable just enough for you do replace the IPrincipal (User) and IIdentity.

The following code runs as expected, even in a console application:

HttpContext.Current = new HttpContext(
    new HttpRequest("", "http://tempuri.org", ""),
    new HttpResponse(new StringWriter())
    );

// User is logged in
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity("username"),
    new string[0]
    );

// User is logged out
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity(String.Empty),
    new string[0]
    );

You could try this:

$in_str = 'this is a test';
$hex_ary = array();
foreach (str_split($in_str) as $chr) {
    $hex_ary[] = sprintf("%02X", ord($chr));
}
echo implode(' ',$hex_ary);

Actually On my windows 10 with visual studio 2017 community, the C++ headers path are:

1. C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\include

2. C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0\ucrt

The 1st contains standard C++ headers such as <iostream>, <algorithm>. The 2nd contains old C headers such as <stdio.h>, <string.h>. The version number can be different based on your software.

Hope this would help.

The above mentioned answers are correct but I am simplifying it for noobs like me.Go to your project's pom file. Add a new property exec.mainClass and give its value as the class which contains your main method. For me it was DriverClass in mainpkg. Change it as per your project.

Having done this navigate to the folder that contains your project's pom.xml and run this on the command prompt mvn exec:java. This should call the main method.

I think this works:

$(document).ready(function(){

    // Hide (collapse) the toggle containers on load
    $(".toggle_container").hide();

    // Switch the "Open" and "Close" state per click then 
    // slide up/down (depending on open/close state)
    $("h2.trigger").click(function(){
        $(this).toggleClass("active").next().slideToggle("slow");
        return false; // Prevent the browser jump to the link anchor
    });
});

As dudewat said external linkage means the symbol (function or global variable) is accessible throughout your program and internal linkage means that it is only accessible in one translation unit.

You can explicitly control the linkage of a symbol by using the extern and static keywords. If the linkage is not specified then the default linkage is extern (external linkage) for non-const symbols and static (internal linkage) for const symbols.

// In namespace scope or global scope.
int i; // extern by default
const int ci; // static by default
extern const int eci; // explicitly extern
static int si; // explicitly static

// The same goes for functions (but there are no const functions).
int f(); // extern by default
static int sf(); // explicitly static 

Note that instead of using static (internal linkage), it is better to use anonymous namespaces into which you can also put classes. Though they allow extern linkage, anonymous namespaces are unreachable from other translation units, making linkage effectively static.

namespace {
  int i; // extern by default but unreachable from other translation units
  class C; // extern by default but unreachable from other translation units
}

There is the possibility of making something really more cool!

JSON in Java has some great resources.

Maven dependency:

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20180813</version>
</dependency>

XML.java is the class you're looking for:

import org.json.JSONObject;
import org.json.XML;
import org.json.JSONException;

public class Main {

    public static int PRETTY_PRINT_INDENT_FACTOR = 4;
    public static String TEST_XML_STRING =
        "<?xml version=\"1.0\" ?><test attrib=\"moretest\">Turn this to JSON</test>";

    public static void main(String[] args) {
        try {
            JSONObject xmlJSONObj = XML.toJSONObject(TEST_XML_STRING);
            String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
            System.out.println(jsonPrettyPrintString);
        } catch (JSONException je) {
            System.out.println(je.toString());
        }
    }
}

Output is:

{"test": {
    "attrib": "moretest",
    "content": "Turn this to JSON"
}}

This one worked for me.

Now it has become very easy, You can do it by simply declaring jQuery variable with any type inside Angular2 controller.

declare var jQuery:any;

Add this just after import statements and before component decorator.

To access any element with id X or Class X you just have to do

jQuery("#X or .X").someFunc();

The approach I suggest is a bit verbose but I found it to scale pretty well into complex apps. When you want to show a modal, fire an action describing which modal you'd like to see:

Dispatching an Action to Show the Modal

this.props.dispatch({
  type: 'SHOW_MODAL',
  modalType: 'DELETE_POST',
  modalProps: {
    postId: 42
  }
})

(Strings can be constants of course; I’m using inline strings for simplicity.)

Writing a Reducer to Manage Modal State

Then make sure you have a reducer that just accepts these values:

const initialState = {
  modalType: null,
  modalProps: {}
}

function modal(state = initialState, action) {
  switch (action.type) {
    case 'SHOW_MODAL':
      return {
        modalType: action.modalType,
        modalProps: action.modalProps
      }
    case 'HIDE_MODAL':
      return initialState
    default:
      return state
  }
}

/* .... */

const rootReducer = combineReducers({
  modal,
  /* other reducers */
})

Great! Now, when you dispatch an action, state.modal will update to include the information about the currently visible modal window.

Writing the Root Modal Component

At the root of your component hierarchy, add a <ModalRoot> component that is connected to the Redux store. It will listen to state.modal and display an appropriate modal component, forwarding the props from the state.modal.modalProps.

// These are regular React components we will write soon
import DeletePostModal from './DeletePostModal'
import ConfirmLogoutModal from './ConfirmLogoutModal'

const MODAL_COMPONENTS = {
  'DELETE_POST': DeletePostModal,
  'CONFIRM_LOGOUT': ConfirmLogoutModal,
  /* other modals */
}

const ModalRoot = ({ modalType, modalProps }) => {
  if (!modalType) {
    return <span /> // after React v15 you can return null here
  }

  const SpecificModal = MODAL_COMPONENTS[modalType]
  return <SpecificModal {...modalProps} />
}

export default connect(
  state => state.modal
)(ModalRoot)

What have we done here? ModalRoot reads the current modalType and modalProps from state.modal to which it is connected, and renders a corresponding component such as DeletePostModal or ConfirmLogoutModal. Every modal is a component!

Writing Specific Modal Components

There are no general rules here. They are just React components that can dispatch actions, read something from the store state, and just happen to be modals.

For example, DeletePostModal might look like:

import { deletePost, hideModal } from '../actions'

const DeletePostModal = ({ post, dispatch }) => (
  <div>
    <p>Delete post {post.name}?</p>
    <button onClick={() => {
      dispatch(deletePost(post.id)).then(() => {
        dispatch(hideModal())
      })
    }}>
      Yes
    </button>
    <button onClick={() => dispatch(hideModal())}>
      Nope
    </button>
  </div>
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)

The DeletePostModal is connected to the store so it can display the post title and works like any connected component: it can dispatch actions, including hideModal when it is necessary to hide itself.

Extracting a Presentational Component

It would be awkward to copy-paste the same layout logic for every “specific” modal. But you have components, right? So you can extract a presentational <Modal> component that doesn’t know what particular modals do, but handles how they look.

Then, specific modals such as DeletePostModal can use it for rendering:

import { deletePost, hideModal } from '../actions'
import Modal from './Modal'

const DeletePostModal = ({ post, dispatch }) => (
  <Modal
    dangerText={`Delete post ${post.name}?`}
    onDangerClick={() =>
      dispatch(deletePost(post.id)).then(() => {
        dispatch(hideModal())
      })
    })
  />
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)

It is up to you to come up with a set of props that <Modal> can accept in your application but I would imagine that you might have several kinds of modals (e.g. info modal, confirmation modal, etc), and several styles for them.

Accessibility and Hiding on Click Outside or Escape Key

The last important part about modals is that generally we want to hide them when the user clicks outside or presses Escape.

Instead of giving you advice on implementing this, I suggest that you just don’t implement it yourself. It is hard to get right considering accessibility.

Instead, I would suggest you to use an accessible off-the-shelf modal component such as react-modal. It is completely customizable, you can put anything you want inside of it, but it handles accessibility correctly so that blind people can still use your modal.

You can even wrap react-modal in your own <Modal> that accepts props specific to your applications and generates child buttons or other content. It’s all just components!

Other Approaches

There is more than one way to do it.

Some people don’t like the verbosity of this approach and prefer to have a <Modal> component that they can render right inside their components with a technique called “portals”. Portals let you render a component inside yours while actually it will render at a predetermined place in the DOM, which is very convenient for modals.

In fact react-modal I linked to earlier already does that internally so technically you don’t even need to render it from the top. I still find it nice to decouple the modal I want to show from the component showing it, but you can also use react-modal directly from your components, and skip most of what I wrote above.

I encourage you to consider both approaches, experiment with them, and pick what you find works best for your app and for your team.

As Mike way says. Change target BEFORE doing anything in your project that requires a higher target like android:installLocation="auto".

Use this:

var arr = $('input:checkbox:checked').map(function () {
  return this.value;
}).get();

I implemented compile on save with gulp task using gulp-typescript and incremental build. This allows to control compilation whatever you want. Notice my variable tsServerProject, in my real project I also have tsClientProject because I want to compile my client code with no module specified. As I know you can't do it with vs code.

var gulp = require('gulp'),
    ts = require('gulp-typescript'),
    sourcemaps = require('gulp-sourcemaps');

var tsServerProject = ts.createProject({
   declarationFiles: false,
   noExternalResolve: false,
   module: 'commonjs',
   target: 'ES5'
});

var srcServer = 'src/server/**/*.ts'

gulp.task('watch-server', ['compile-server'], watchServer);
gulp.task('compile-server', compileServer);

function watchServer(params) {
   gulp.watch(srcServer, ['compile-server']);
}

function compileServer(params) {
   var tsResult = gulp.src(srcServer)
      .pipe(sourcemaps.init())
      .pipe(ts(tsServerProject));

   return tsResult.js
      .pipe(sourcemaps.write('./source-maps'))
      .pipe(gulp.dest('src/server/'));

}

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

Adding margin to align images:

Since we wanted the image to be left-aligned, we added:

img {
  margin-right: auto;
}

Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.

Good Luck...

The @CustID means it's a parameter that you will supply a value for later in your code. This is the best way of protecting against SQL injection. Create your query using parameters, rather than concatenating strings and variables. The database engine puts the parameter value into where the placeholder is, and there is zero chance for SQL injection.

I made the following 'universal' cross thread call class for my own purpose, but I think it's worth to share it:

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;

namespace CrossThreadCalls
{
  public static class clsCrossThreadCalls
  {
    private delegate void SetAnyPropertyCallBack(Control c, string Property, object Value);
    public static void SetAnyProperty(Control c, string Property, object Value)
    {
      if (c.GetType().GetProperty(Property) != null)
      {
        //The given property exists
        if (c.InvokeRequired)
        {
          SetAnyPropertyCallBack d = new SetAnyPropertyCallBack(SetAnyProperty);
          c.BeginInvoke(d, c, Property, Value);
        }
        else
        {
          c.GetType().GetProperty(Property).SetValue(c, Value, null);
        }
      }
    }

    private delegate void SetTextPropertyCallBack(Control c, string Value);
    public static void SetTextProperty(Control c, string Value)
    {
      if (c.InvokeRequired)
      {
        SetTextPropertyCallBack d = new SetTextPropertyCallBack(SetTextProperty);
        c.BeginInvoke(d, c, Value);
      }
      else
      {
        c.Text = Value;
      }
    }
  }

And you can simply use SetAnyProperty() from another thread:

CrossThreadCalls.clsCrossThreadCalls.SetAnyProperty(lb_Speed, "Text", KvaserCanReader.GetSpeed.ToString());

In this example the above KvaserCanReader class runs its own thread and makes a call to set the text property of the lb_Speed label on the main form.

Yahoo's api provides a CSV dump:

i think you can not add count() with where. now see why ....

where is not same as having , having means you are working or dealing with group and same work of count , it is also dealing with the whole group ,

now how count it is working as whole group

create a table and enter some id's and then use:

select count(*) from table_name

you will find the total values means it is indicating some group ! so where does added with count() ;

A pipe takes in data as input and transforms it to a desired output. Add this pipe file:orderby.ts inside your /app folder .

orderby.ts

//The pipe class implements the PipeTransform interface's transform method that accepts an input value and an optional array of parameters and returns the transformed value.

import { Pipe,PipeTransform } from "angular2/core";

//We tell Angular that this is a pipe by applying the @Pipe decorator which we import from the core Angular library.

@Pipe({

  //The @Pipe decorator takes an object with a name property whose value is the pipe name that we'll use within a template expression. It must be a valid JavaScript identifier. Our pipe's name is orderby.

  name: "orderby"
})

export class OrderByPipe implements PipeTransform {
  transform(array:Array<any>, args?) {

    // Check if array exists, in this case array contains articles and args is an array that has 1 element : !id

    if(array) {

      // get the first element

      let orderByValue = args[0]
      let byVal = 1

      // check if exclamation point 

      if(orderByValue.charAt(0) == "!") {

        // reverse the array

        byVal = -1
        orderByValue = orderByValue.substring(1)
      }
      console.log("byVal",byVal);
      console.log("orderByValue",orderByValue);

      array.sort((a: any, b: any) => {
        if(a[orderByValue] < b[orderByValue]) {
          return -1*byVal;
        } else if (a[orderByValue] > b[orderByValue]) {
          return 1*byVal;
        } else {
          return 0;
        }
      });
      return array;
    }
    //
  }
}

In your component file (app.component.ts) import the pipe that you just added using: import {OrderByPipe} from './orderby';

Then, add *ngFor="#article of articles | orderby:'id'" inside your template if you want to sort your articles by id in ascending order or orderby:'!id'" in descending order.

We add parameters to a pipe by following the pipe name with a colon ( : ) and then the parameter value

We must list our pipe in the pipes array of the @Component decorator. pipes: [ OrderByPipe ] .

app.component.ts

import {Component, OnInit} from 'angular2/core';
import {OrderByPipe} from './orderby';

@Component({
    selector: 'my-app',
    template: `
      <h2>orderby-pipe by N2B</h2>
      <p *ngFor="#article of articles | orderby:'id'">
        Article title : {{article.title}}

I have been searching for this for ages on my CM 11 android phone, running kitkat.

Well.. finally I found it. It's hidden in a totally unintuitive location:

1. Go to settings
2. Go to storage
3. Open the menu and choose USB computer connection

Here you can choose between Media Device (MTP), Camera (PTP) and Mass storage (UMS). Turn them all off to get it to charge only.

Sadly, if the option is not there, it is not supported by the phone. This seems to be the case for my HTC One (M7).

Comparable is usually preferred. But sometimes a class already implements Comparable, but you want to sort on a different property. Then you're forced to use a Comparator.

Some classes actually provide Comparators for common cases; for instance, Strings are by default case-sensitive when sorted, but there is also a static Comparator called CASE_INSENSITIVE_ORDER.

Since nobody has added the obvious solution yet which works fine for two comparisons, I'll offer it:

if (foobar === foo || foobar === bar) {
     //do something
}

And, if you have lots of values (perhaps hundreds or thousands), then I'd suggest making a Set as this makes very clean and simple comparison code and it's fast at runtime:

// pre-construct the Set
var tSet = new Set(["foo", "bar", "test1", "test2", "test3", ...]);

// test the Set at runtime
if (tSet.has(foobar)) {
    // do something
}

For pre-ES6, you can get a Set polyfill of which there are many. One is described in this other answer.

As previously mentioned - in case of a project, Makefile or otherwise, this is a project configuration issue, where you'll likely need to specify other flags too.

But what about one-off programs, where you would normally just write g++ file.cpp && ./a.out?

Well, I would much like to have some #pragma to turn in on at source level, or maybe a default extension - say .cxx or .C11 or whatever, trigger it by default. But as of today, there is no such feature.

But, as you probably are working in a manual environment (i.e. shell), you can just have an alias in you .bashrc (or whatever):

alias g++11="g++ -std=c++0x"

or, for newer G++ (and when you want to feel "real C++11")

alias g++11="g++ -std=c++11"

You can even alias to g++ itself, if you hate C++03 that much ;)

This may happen when the npm/lib folder got emptied for some reason (could also happen due to permission issues in the last usage).

A reinstallation of the node could solve the issue (as stated on other answers here), but I would suggest using a wonderful tool called nvm (Node Version Manager), which is able to manage multiple version of node and npm - this is mostly useful on dev machines with more than one projects require different versions of node.

When you install nvm, this message will go away and you will have the latest version of node and npm to use.

In order to see the list of currently installed node versions in your nvm, just run:

nvm list

In order to install and use a new node version, run:

nvm install <node_version>

For example to install latest version of node 10.x, run:

nvm install 10

In order to switch to currently installed version, run:

nvm use <node_version>

In order to switch to system's original node version, just run:

nvm use system

Hope this helps.

Good luck!

As other users have mentioned, enumerate is a generator that adds an incremental index next to each item of an iterable.

So if you have a list say l = ["test_1", "test_2", "test_3"], the list(enumerate(l)) will give you something like this: [(0, 'test_1'), (1, 'test_2'), (2, 'test_3')].

Now, when this is useful? A possible use case is when you want to iterate over items, and you want to skip a specific item that you only know its index in the list but not its value (because its value is not known at the time).

for index, value in enumerate(joint_values):
   if index == 3:
       continue

   # Do something with the other `value`

So your code reads better because you could also do a regular for loop with range but then to access the items you need to index them (i.e., joint_values[i]).

Although another user mentioned an implementation of enumerate using zip, I think a more pure (but slightly more complex) way without using itertools is the following:

def enumerate(l, start=0):
    return zip(range(start, len(l) + start), l)

Example:

l = ["test_1", "test_2", "test_3"]
enumerate(l)
enumerate(l, 10)

Output:

[(0, 'test_1'), (1, 'test_2'), (2, 'test_3')]

[(10, 'test_1'), (11, 'test_2'), (12, 'test_3')]

As mentioned in the comments, this approach with range will not work with arbitrary iterables as the original enumerate function does.

Google java http client has nice API for http requests. You can easily add JSON support etc. Although for simple request it might be overkill.

import com.google.api.client.http.GenericUrl;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpResponse;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import java.io.IOException;
import java.io.InputStream;

public class Network {

    static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

    public void getRequest(String reqUrl) throws IOException {
        GenericUrl url = new GenericUrl(reqUrl);
        HttpRequest request = HTTP_TRANSPORT.createRequestFactory().buildGetRequest(url);
        HttpResponse response = request.execute();
        System.out.println(response.getStatusCode());

        InputStream is = response.getContent();
        int ch;
        while ((ch = is.read()) != -1) {
            System.out.print((char) ch);
        }
        response.disconnect();
    }
}

This can be a good option if you want python completion as well as other languages. https://github.com/Valloric/YouCompleteMe

The python completion is jedi based same as jedi-vim.

If you want to delete the file from the repo, but leave it in the the file system (will be untracked):

bykov@gitserver:~/temp> git rm --cached file1.txt
bykov@gitserver:~/temp> git commit -m "remove file1.txt from the repo"

If you want to delete the file from the repo and from the file system then there are two options:

1. If the file has no changes staged in the index:

   bykov@gitserver:~/temp> git rm file1.txt
   bykov@gitserver:~/temp> git commit -m "remove file1.txt"
   

2. If the file has changes staged in the index:

   bykov@gitserver:~/temp> git rm -f file1.txt
   bykov@gitserver:~/temp> git commit -m "remove file1.txt"
   

The object and array literal syntax {}/[] was introduced in JavaScript 1.2, so is not available (and will produce a syntax error) in versions of Netscape Navigator prior to 4.0.

My fingers still default to saying new Array(), but I am a very old man. Thankfully Netscape 3 is not a browser many people ever have to consider today...

// apparently this is broken. Whoops for me!
java.util.Collections.fill(list,new Integer(0));

// this is better
Integer[] data = new Integer[60];
Arrays.fill(data,new Integer(0));
List<Integer> list = Arrays.asList(data);

The ideal solution would be to use inline-block for the columns instead of floating. I think the browser support is pretty good if you follow (a) apply inline-block only to elements that are normally inline (eg span); and (b) add -moz-inline-box for Firefox.

Check your page in FF2 as well because I had a ton of problems when nesting certain elements (surprisingly, this is the one case where IE performs much better than FF).

Inside Activity.onCreate() callback or in the another place where you need to change title:

getSupportActionBar().setTitle("Whatever title");

You could also do the following:

// untested
Calendar cal = GregorianCalendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 23);// I might have the wrong Calendar constant...
cal.set(Calendar.MONTH, 8);// -1 as month is zero-based
cal.set(Calendar.YEAR, 2009);
Timestamp tstamp = new Timestamp(cal.getTimeInMillis());

I know that you don't need to trust all certificates but in my case I had problems with some debugging environments where we had self-signed certificates and I needed a dirty solution.

All I had to do was to change the initialization of the sslContext

mySSLContext.init(null, trustAllCerts, null); 

where trustAllCerts was created like this:

private final TrustManager[] trustAllCerts= new TrustManager[] { new X509TrustManager() {
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return new java.security.cert.X509Certificate[]{};
    }

    public void checkClientTrusted(X509Certificate[] chain,
                                   String authType) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] chain,
                                   String authType) throws CertificateException {
    }
} };

Hope that this will come in handy.

//javascript
//teams.Table does not exist

function OnSuccessJSON(data, status) {
    var teams = eval('(' + data.d + ')');
    var listItems = "";
    for (var i = 0; i < teams.length; i++) {
      listItems += "<option value='" + teams[i][0]+ "'>" + teams[i][1] + "</option>";
    }
    $("#<%=ddlTeams.ClientID%>").html(listItems);
} 

You can do this simply like this

$('#image_id').click(function() {
  $("#some_id iframe").attr('src', $("#some_id iframe", parent).attr('src') + '?autoplay=1'); 
});

where image_id is your image id you are clicking and some_id is id of div in which iframe is also you can use iframe id directly.

To append to this famous question (though a bit too late): You can also do df.groupby('column_name').get_group('column_desired_value').reset_index() to make a new data frame with specified column having a particular value. E.g.

import pandas as pd
df = pd.DataFrame({'A': 'foo bar foo bar foo bar foo foo'.split(),
                   'B': 'one one two three two two one three'.split()})
print("Original dataframe:")
print(df)

b_is_two_dataframe = pd.DataFrame(df.groupby('B').get_group('two').reset_index()).drop('index', axis = 1) 
#NOTE: the final drop is to remove the extra index column returned by groupby object
print('Sub dataframe where B is two:')
print(b_is_two_dataframe)

Run this gives:

Original dataframe:
     A      B
0  foo    one
1  bar    one
2  foo    two
3  bar  three
4  foo    two
5  bar    two
6  foo    one
7  foo  three
Sub dataframe where B is two:
     A    B
0  foo  two
1  foo  two
2  bar  two

Just with the above answer I hope it was the problem.

$_POST['search'] instead of $_post['search']

And again use LIKE '%$name%' instead of LIKE '%{$name}%'

Another option is to use the params keyword

public void DoSomething(params object[] theObjects)
{
  foreach(object o in theObjects)
  {
    // Something with the Objects…
  }
}

Called like...

DoSomething(this, that, theOther);

Please make sure that you are not consuming your inputstream anywhere before parsing. Sample code is following: the respose below is httpresponse(i.e. response) and main content is contain inside StringEntity (i.e. getEntity())in form of inputStream(i.e. getContent()).

InputStream rescontent = response.getEntity().getContent();
tsResponse=(TsResponse) transformer.convertFromXMLToObject(rescontent );

Runtime rt = Runtime.getRuntime();
rt.maxMemory()

value is b

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
am.getMemoryClass()

value is MB

I was able to fix this by downgrading RubyGems to 1.5.3, since it happens with RubyGems 1.6.0+ and Rails < 2.3.11:

gem update --system 1.5.3

If you had previously downgraded to an even earlier version and want to update to 1.5.3, you might get the following when trying to run that:

Updating RubyGems
ERROR:  While executing gem ... (RuntimeError)
    No gem names are allowed with the --system option

If you get that error, then update, so that it lets you specify the version, and then downgrade again:

gem update --system
gem update --system 1.5.3

This is now a thing in C#:

var (a, b, c) = (1, 2, 3);

By doing the above, you have basically declared three variables. a = 1, b = 2 and c = 3. All in a single line.

A) The main GUI thread will run endlessly on the call to Application.Run, so your while loop will never be reached

B) You would never want to have an endless loop like that (the while(true) loop) - it would simply freeze the thread. Not really sure what you're trying to achieve there.

I would create and show the "main" (initial) form in the Main method (as Visual Studio does for you by default). Then in your button handler, create the other form and show it as well as hiding the main form (not closing it). Then, ensure that the main form is shown again when that form is closed via an event. Example:

public partial class Form1 : Form
{
  public Form1()
  {
    InitializeComponent();
  }    

  private void button1_Click(object sender, EventArgs e)
  {      
    Form2 otherForm = new Form2();
    otherForm.FormClosed += new FormClosedEventHandler(otherForm_FormClosed);
    this.Hide();
    otherForm.Show();      
  }

  void otherForm_FormClosed(object sender, FormClosedEventArgs e)
  {
    this.Show();      
  }
}

I have not used Bootstrap but I worked on Zurb Foundation. On that I used to add space like this.

<div id="main" class="container" role="main">
    <div class="row">

        <div class="span5 offset1">
            <h2>Welcome</h2>
            <p>Hello and welcome to my website.</p>
        </div>
        <div class="span6">
            Image Here (TODO)
        </div>
    </div>

Visit this link: http://getbootstrap.com/2.3.2/scaffolding.html and read the section: Offsetting columns.

I think I know what you are doing wrong. If you are applying padding to the span6 like this:

<div class="span6" style="padding-left:5px;">
    <h2>Welcome</h2>
    <p>Hello and welcome to my website.</p>
</div>

It is wrong. What you have to do is add padding to the elements inside:

<div class="span6">
    <h2 style="padding-left:5px;">Welcome</h2>
    <p  style="padding-left:5px;">Hello and welcome to my website.</p>
</div>

For windows:

system("rmdir ".escapeshellarg($path) . " /s /q");

I prefer this:

str = "[12,23,987,43"
puts str[1..-1]
>> 12,23,987,43

I wonder same. The API of Assert is not very symmetric; for testing whether objects are the same, it provides assertSame and assertNotSame.

Of course, it is not too long to write:

assertFalse(foo.equals(bar));

With such an assertion, the only informative part of the output is unfortunately the name of the test method, so descriptive message should be formed separately:

String msg = "Expected <" + foo + "> to be unequal to <" + bar +">";
assertFalse(msg, foo.equals(bar));

That is of course so tedious, that it is better to roll your own assertNotEqual. Luckily in future it will maybe be part of the JUnit: JUnit issue 22

Interesting it works for you. When I tried your solution an error came up, saying that "Type mismatch: cannot convert from SQLQuery to Query". --> Therefore my solution looks like:

SQLQuery query = session.createSQLQuery("select nextval('SEQUENCE_NAME')");
Long nextValue = ((BigInteger)query.uniqueResult()).longValue();

With that solution I didn't run into performance problems.

And don't forget to reset your value, if you just wanted to know for information purposes.

    --nextValue;
    query = session.createSQLQuery("select setval('SEQUENCE_NAME'," + nextValue + ")");

I suggest to use this official way from MySql:

SELECT article, dealer, price
FROM   shop s1
WHERE  price=(SELECT MAX(s2.price)
              FROM shop s2
              WHERE s1.article = s2.article
              GROUP BY s2.article)
ORDER BY article;

With this way, we can get the highest price on each article

The code below reads for any text files available in the directory which contains the script we are running. Then it opens every text file and stores the words of the text line into a list. After store the words we print each word line by line

import os, fnmatch

listOfFiles = os.listdir('.')
pattern = "*.txt"
store = []
for entry in listOfFiles:
    if fnmatch.fnmatch(entry, pattern):
        _fileName = open(entry,"r")
        if _fileName.mode == "r":
            content = _fileName.read()
            contentList = content.split(" ")
            for i in contentList:
                if i != '\n' and i != "\r\n":
                    store.append(i)

for i in store:
    print(i)

After the post from Gabor Grothendieck post at the r-help mailing list

years<-c("20 years old", "1 years old")

library(gsubfn)
pat <- "[-+.e0-9]*\\d"
sapply(years, function(x) strapply(x, pat, as.numeric)[[1]])

You have to catch the error just as you're already doing for your save() call and since you're handling multiple errors here, you can try multiple calls sequentially in a single do-catch block, like so:

func deleteAccountDetail() {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()
    request.entity = entityDescription

    do {
        let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]

        for entity in fetchedEntities {
            self.Context!.deleteObject(entity)
        }

        try self.Context!.save()
    } catch {
        print(error)
    }
}

Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws then try to call the method. For example:

func deleteAccountDetail() throws {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()

    request.entity = entityDescription

    let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]

    for entity in fetchedEntities {
        self.Context!.deleteObject(entity)
    }

    try self.Context!.save()
}

Everyone is right. You can't print an int[] object out directly, but there's also no need to not use an ArrayList of integer arrays.

Using,

Arrays.toString(arl.get(0))

means splitting the String object into a substring if you want to insert anything in between, such as commas.

Here's what I think amv was looking for from an int array viewpoint.

System.out.println("Arraylist contains: " 
    + arl.get(0)[0] + ", " 
    + arl.get(0)[1] + ", " 
    + arl.get(0)[2]);

This answer is a little late for amv but still may be useful to others.

I have the same error. Not sure why it happened. But I managed to upgrade by running:

pip install setuptools --upgrade --ignore-installed

After that, I used a PowerShell or Command Prompt - cmd in administrator mode to install the package:

pip install the-package

# or
easy_install the-package

Also, what they have already suggested: Installing packages using pip and virtual environments , which is the best practice for new projects.

If you know x and y are both strings, using === is not strictly necessary, but is still good practice.

Assuming both variables actually are strings, both operators will function identically. However, TS often allows you to pass an object that meets all the requirements of string rather than an actual string, which may complicate things.

Given the possibility of confusion or changes in the future, your linter is probably correct in demanding ===. Just go with that.

Yes, there is a way without any 3rd party extension.

I've built javascript-snippet (which you can add as browser-bookmark) and then activate on any site to monitor & modify the requests. :

If your problem is like the following while using Google Chrome:

[XMLHttpRequest cannot load file. Received an invalid response. Origin 'null' is therefore not allowed access.]

Then create a batch file by following these steps:

Open notepad in Desktop.

1. Just copy and paste the followings in your currently opened notepad file:

start "chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files exit

1. Note: In the previous line, Replace the full absolute address with your location of chrome installation. [To find it...Right click your short cut of chrome.exe link or icon and Click on Properties and copy-paste the target link][Remember : start to files in one line, & exit in another line by pressing enter]
2. Save the file as fileName.bat [Very important: .bat]
3. If you want to change the file later then right-click on the .bat file and click on edit. After modifying, save the file.

This will do what? It will open Chrome.exe with file access. Now, from any location in your computer, browse your html files with Google Chrome. I hope this will solve the XMLHttpRequest problem.

Keep in mind : Just use the shortcut bat file to open Chrome when you require it. Tell me if it solves your problem. I had a similar problem and I solved it in this way. Thanks.

One more thing that prevents the mysqld windows service from running is if you have mysqld.exe already running (but not as a service) and occupying port 3306. When the service tries to start and sees that port 3306 is already taken, it fails.

Just open up the windows task manager and look for "mysqld.exe" under the Processes tab. If you see it, kill it and then try to start the service again.

c:\> net start [servicename]

example: c:\> net start MySQL

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

Give this a try:

SELECT
    CONSTRAINT_CATALOG AS DataBaseName,
    CONSTRAINT_SCHEMA AS SchemaName,
    TABLE_NAME AS TableName,
    CONSTRAINT_Name AS PrimaryKey
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
WHERE CONSTRAINT_TYPE = 'Primary Key' and Table_Name = 'YourTable'

From R..'s answer:

However, this is probably a very bad idea, because the resulting type is an array type, but users of it won't see that it's an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong.

Users who don't see that it's an array will most likely write something like this (which fails):

#include <stdio.h>

typedef int twoInts[2];

void print(twoInts *twoIntsPtr);
void intermediate (twoInts twoIntsAppearsByValue);

int main () {
    twoInts a;
    a[0] = 0;
    a[1] = 1;
    print(&a);
    intermediate(a);
    return 0;
}
void intermediate(twoInts b) {
    print(&b);
}

void print(twoInts *c){
    printf("%d\n%d\n", (*c)[0], (*c)[1]);
}

It will compile with the following warnings:

In function ‘intermediate’:
warning: passing argument 1 of ‘print’ from incompatible pointer type [enabled by default]
    print(&b);
     ^
note: expected ‘int (*)[2]’ but argument is of type ‘int **’
    void print(twoInts *twoIntsPtr);
         ^

And produces the following output:

0
1
-453308976
32767

You can also use the good old micro clearfix for this.

#container::before, #container::after{
    content: ' ';
    display: table;
}

There is no button type="cancel" in html. You can try like this

<a href="http://www.url.com/yourpage.php">Cancel</a>

You can make it look like a button by using CSS style properties.

You just need to use the Gradle Application plugin:

apply plugin:'application'
mainClassName = "org.gradle.sample.Main"

And then simply gradle run.

As Teresa points out, you can also configure mainClassName as a system property and run with a command line argument.

This is not about the difference between Window.ContentRendered and Window.Loaded but about what how the Window.Loaded event can be used:

I use it to avoid splash screens in all applications which need a long time to come up.

    // initializing my main window
    public MyAppMainWindow()
    {
        InitializeComponent();

        // Set the event
        this.ContentRendered += MyAppMainWindow_ContentRendered;
    }

    private void MyAppMainWindow_ContentRendered(object sender, EventArgs e)
    {
        // ... comes up quick when the controls are loaded and rendered

        // unset the event
        this.ContentRendered -= MyAppMainWindow_ContentRendered;

        // ... make the time comsuming init stuff here
    }

You could use for() with assign() to create many objects. See the example from assign():

for(i in 1:6) { #-- Create objects  'r.1', 'r.2', ... 'r.6' --
    nam <- paste("r", i, sep = ".")
    assign(nam, 1:i)

Looking the new objects

ls(pattern = "^r..$")

The directions state:

1. Download the appropriate Instant Client packages for your platform. All installations REQUIRE the Basic package.
2. Unzip the packages into a single directory such as "instantclient".
3. Set the library loading path in your environment to the directory in Step 2 ("instantclient"). On many UNIX platforms, LD_LIBRARY_PATH is the appropriate environment variable. On Windows, PATH should be used.
4. Start your application and enjoy.

Suggest extracting/unzipping into a new directory. They've suggested instantclient, but you can name the directory anything you like. Name it C:\OracleInstantClient\ if you choose.

Then in Step 3, open a Windows Command Prompt. Type:

PATH C:\OracleInstantClient; %PATH%`

That's all there is to it!

The simplest solution might be to limit the number of characters in the HTML itself. Rails has a truncate(string, length) helper, and I'm certain that whichever backend you're using provides something similar.

Due to the cross-browser issues you're already familiar with regarding the width of select boxes, this seems to me to be the most straightforward and least error-prone option.

<select>
  <option value="1">One</option>
  <option value="100">One hund...</option>
<select>

It is possible to do (in the deployed repository):

git fetch
// git fetch will download all the recent changes, but it will not put it in your current checked out code (working area).

Followed by:

git checkout origin/master -- path/to/file
// git checkout <local repo name (default is origin)>/<branch name> -- path/to/file will checkout the particular file from the downloaded changes (origin/master).

You need to start your Apache Server normally you should have an xampp icon in the info-section from the taskbar, with this tool you can start the apache server as wel as the mysql database (if you need it)

You have to add THEN

IF EXISTS(SELECT * FROM component_psar WHERE tbl_id = '2' AND row_nr = '1') 
THEN
UPDATE component_psar SET col_1 = '1', col_2 = '1', col_3 = '1', col_4 = '1', col_5 = '1', col_6 = '1', unit = '1', add_info = '1', fsar_lock = '1' WHERE tbl_id = '2' AND row_nr = '1' 
ELSE 
INSERT INTO component_psar (tbl_id, row_nr, col_1, col_2, col_3, col_4, col_5, col_6, unit, add_info, fsar_lock) VALUES('2', '1', '1', '1', '1', '1', '1', '1', '1', '1', 'N')

Stuarts' answer is correct, but if you are not sure if you are saving the titles in lowercase, you can also make a case insensitive search

There are a lot of answered questions in Stack Overflow with more data on this:

Yes, you can do the same in Seaborn directly. This is done with tsplot() which allows either a single array as input, or two arrays where the other is 'time' i.e. x-axis.

import seaborn as sns

data =  [1,5,3,2,6] * 20
time = range(100)

sns.tsplot(data, time)

Sliding the space bar only works if you gave more then one input language selected.

In that case the space bar will also indicate the selected language and show arrows to indicate Sliding will change selection.

This is easy fast and changes the dictionary at the same time.

First response seems the mist accurate.

I would rather create a map

export class item{
    name: string; 
    id: string
}

let caches = new Map<string, item>();

and then you can simply

this.caches[newitem.id] = newitem; 

even

this.caches.set(newitem.id, newitem); 

array is so 1999. :)

Accepted answer doesn't work for me, but this does. Ensure script in the location (c:\temp_ below on each remote server. servers.txt contains a list of IP addresses (one per line).

psexec @servers.txt -u <username> cmd /c "powershell -noninteractive -file C:\temp\script.ps1"

So, pretty much here is your problem. The close button on the upper right of a window frame is not part of the WPF window, but it belongs to the part of the window frame that is controled by your OS. This means you will have to use Win32 interop to do it.

alternativly, you can use the noframe and either provide your own "frame" or have no frame at all.

In case of Oracle since 12c you have DEFAULT ON NULL which implies a NOT NULL constraint.

ALTER TABLE tbl ADD (col VARCHAR(20) DEFAULT ON NULL 'MyDefault');

ALTER TABLE

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified. If you specify an inline constraint that conflicts with NOT NULL and NOT DEFERRABLE, then an error is raised.

To check if a string is empty or contains only whitespace you could use:

shopt -s extglob  # more powerful pattern matching

if [ -n "${str##+([[:space:]])}" ]; then
    echo '$str is not null or space'
fi

You can easily pick image from asset without UIImage(named: "green-square-Retina").

Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.

Your problem with Vim is that you don't grok vi.

You mention cutting with yy and complain that you almost never want to cut whole lines. In fact programmers, editing source code, very often want to work on whole lines, ranges of lines and blocks of code. However, yy is only one of many way to yank text into the anonymous copy buffer (or "register" as it's called in vi).

The "Zen" of vi is that you're speaking a language. The initial y is a verb. The statement yy is a synonym for y_. The y is doubled up to make it easier to type, since it is such a common operation.

This can also be expressed as dd P (delete the current line and paste a copy back into place; leaving a copy in the anonymous register as a side effect). The y and d "verbs" take any movement as their "subject." Thus yW is "yank from here (the cursor) to the end of the current/next (big) word" and y'a is "yank from here to the line containing the mark named 'a'."

If you only understand basic up, down, left, and right cursor movements then vi will be no more productive than a copy of "notepad" for you. (Okay, you'll still have syntax highlighting and the ability to handle files larger than a piddling ~45KB or so; but work with me here).

vi has 26 "marks" and 26 "registers." A mark is set to any cursor location using the m command. Each mark is designated by a single lower case letter. Thus ma sets the 'a' mark to the current location, and mz sets the 'z' mark. You can move to the line containing a mark using the ' (single quote) command. Thus 'a moves to the beginning of the line containing the 'a' mark. You can move to the precise location of any mark using the ` (backquote) command. Thus `z will move directly to the exact location of the 'z' mark.

Because these are "movements" they can also be used as subjects for other "statements."

So, one way to cut an arbitrary selection of text would be to drop a mark (I usually use 'a' as my "first" mark, 'z' as my next mark, 'b' as another, and 'e' as yet another (I don't recall ever having interactively used more than four marks in 15 years of using vi; one creates one's own conventions regarding how marks and registers are used by macros that don't disturb one's interactive context). Then we go to the other end of our desired text; we can start at either end, it doesn't matter. Then we can simply use d`a to cut or y`a to copy. Thus the whole process has a 5 keystrokes overhead (six if we started in "insert" mode and needed to Esc out command mode). Once we've cut or copied then pasting in a copy is a single keystroke: p.

I say that this is one way to cut or copy text. However, it is only one of many. Frequently we can more succinctly describe the range of text without moving our cursor around and dropping a mark. For example if I'm in a paragraph of text I can use { and } movements to the beginning or end of the paragraph respectively. So, to move a paragraph of text I cut it using { d} (3 keystrokes). (If I happen to already be on the first or last line of the paragraph I can then simply use d} or d{ respectively.

The notion of "paragraph" defaults to something which is usually intuitively reasonable. Thus it often works for code as well as prose.

Frequently we know some pattern (regular expression) that marks one end or the other of the text in which we're interested. Searching forwards or backwards are movements in vi. Thus they can also be used as "subjects" in our "statements." So I can use d/foo to cut from the current line to the next line containing the string "foo" and y?bar to copy from the current line to the most recent (previous) line containing "bar." If I don't want whole lines I can still use the search movements (as statements of their own), drop my mark(s) and use the `x commands as described previously.

In addition to "verbs" and "subjects" vi also has "objects" (in the grammatical sense of the term). So far I've only described the use of the anonymous register. However, I can use any of the 26 "named" registers by prefixing the "object" reference with " (the double quote modifier). Thus if I use "add I'm cutting the current line into the 'a' register and if I use "by/foo then I'm yanking a copy of the text from here to the next line containing "foo" into the 'b' register. To paste from a register I simply prefix the paste with the same modifier sequence: "ap pastes a copy of the 'a' register's contents into the text after the cursor and "bP pastes a copy from 'b' to before the current line.

This notion of "prefixes" also adds the analogs of grammatical "adjectives" and "adverbs' to our text manipulation "language." Most commands (verbs) and movement (verbs or objects, depending on context) can also take numeric prefixes. Thus 3J means "join the next three lines" and d5} means "delete from the current line through the end of the fifth paragraph down from here."

This is all intermediate level vi. None of it is Vim specific and there are far more advanced tricks in vi if you're ready to learn them. If you were to master just these intermediate concepts then you'd probably find that you rarely need to write any macros because the text manipulation language is sufficiently concise and expressive to do most things easily enough using the editor's "native" language.

A sampling of more advanced tricks:

There are a number of : commands, most notably the :% s/foo/bar/g global substitution technique. (That's not advanced but other : commands can be). The whole : set of commands was historically inherited by vi's previous incarnations as the ed (line editor) and later the ex (extended line editor) utilities. In fact vi is so named because it's the visual interface to ex.

: commands normally operate over lines of text. ed and ex were written in an era when terminal screens were uncommon and many terminals were "teletype" (TTY) devices. So it was common to work from printed copies of the text, using commands through an extremely terse interface (common connection speeds were 110 baud, or, roughly, 11 characters per second -- which is slower than a fast typist; lags were common on multi-user interactive sessions; additionally there was often some motivation to conserve paper).

So the syntax of most : commands includes an address or range of addresses (line number) followed by a command. Naturally one could use literal line numbers: :127,215 s/foo/bar to change the first occurrence of "foo" into "bar" on each line between 127 and 215. One could also use some abbreviations such as . or $ for current and last lines respectively. One could also use relative prefixes + and - to refer to offsets after or before the curent line, respectively. Thus: :.,$j meaning "from the current line to the last line, join them all into one line". :% is synonymous with :1,$ (all the lines).

The :... g and :... v commands bear some explanation as they are incredibly powerful. :... g is a prefix for "globally" applying a subsequent command to all lines which match a pattern (regular expression) while :... v applies such a command to all lines which do NOT match the given pattern ("v" from "conVerse"). As with other ex commands these can be prefixed by addressing/range references. Thus :.,+21g/foo/d means "delete any lines containing the string "foo" from the current one through the next 21 lines" while :.,$v/bar/d means "from here to the end of the file, delete any lines which DON'T contain the string "bar."

It's interesting that the common Unix command grep was actually inspired by this ex command (and is named after the way in which it was documented). The ex command :g/re/p (grep) was the way they documented how to "globally" "print" lines containing a "regular expression" (re). When ed and ex were used, the :p command was one of the first that anyone learned and often the first one used when editing any file. It was how you printed the current contents (usually just one page full at a time using :.,+25p or some such).

Note that :% g/.../d or (its reVerse/conVerse counterpart: :% v/.../d are the most common usage patterns. However there are couple of other ex commands which are worth remembering:

We can use m to move lines around, and j to join lines. For example if you have a list and you want to separate all the stuff matching (or conversely NOT matching some pattern) without deleting them, then you can use something like: :% g/foo/m$ ... and all the "foo" lines will have been moved to the end of the file. (Note the other tip about using the end of your file as a scratch space). This will have preserved the relative order of all the "foo" lines while having extracted them from the rest of the list. (This would be equivalent to doing something like: 1G!GGmap!Ggrep foo<ENTER>1G:1,'a g/foo'/d (copy the file to its own tail, filter the tail through grep, and delete all the stuff from the head).

To join lines usually I can find a pattern for all the lines which need to be joined to their predecessor (all the lines which start with "^ " rather than "^ * " in some bullet list, for example). For that case I'd use: :% g/^ /-1j (for every matching line, go up one line and join them). (BTW: for bullet lists trying to search for the bullet lines and join to the next doesn't work for a couple reasons ... it can join one bullet line to another, and it won't join any bullet line to all of its continuations; it'll only work pairwise on the matches).

Almost needless to mention you can use our old friend s (substitute) with the g and v (global/converse-global) commands. Usually you don't need to do so. However, consider some case where you want to perform a substitution only on lines matching some other pattern. Often you can use a complicated pattern with captures and use back references to preserve the portions of the lines that you DON'T want to change. However, it will often be easier to separate the match from the substitution: :% g/foo/s/bar/zzz/g -- for every line containing "foo" substitute all "bar" with "zzz." (Something like :% s/\(.*foo.*\)bar\(.*\)/\1zzz\2/g would only work for the cases those instances of "bar" which were PRECEDED by "foo" on the same line; it's ungainly enough already, and would have to be mangled further to catch all the cases where "bar" preceded "foo")

The point is that there are more than just p, s, and d lines in the ex command set.

The : addresses can also refer to marks. Thus you can use: :'a,'bg/foo/j to join any line containing the string foo to its subsequent line, if it lies between the lines between the 'a' and 'b' marks. (Yes, all of the preceding ex command examples can be limited to subsets of the file's lines by prefixing with these sorts of addressing expressions).

That's pretty obscure (I've only used something like that a few times in the last 15 years). However, I'll freely admit that I've often done things iteratively and interactively that could probably have been done more efficiently if I'd taken the time to think out the correct incantation.

Another very useful vi or ex command is :r to read in the contents of another file. Thus: :r foo inserts the contents of the file named "foo" at the current line.

More powerful is the :r! command. This reads the results of a command. It's the same as suspending the vi session, running a command, redirecting its output to a temporary file, resuming your vi session, and reading in the contents from the temp. file.

Even more powerful are the ! (bang) and :... ! (ex bang) commands. These also execute external commands and read the results into the current text. However, they also filter selections of our text through the command! This we can sort all the lines in our file using 1G!Gsort (G is the vi "goto" command; it defaults to going to the last line of the file, but can be prefixed by a line number, such as 1, the first line). This is equivalent to the ex variant :1,$!sort. Writers often use ! with the Unix fmt or fold utilities for reformating or "word wrapping" selections of text. A very common macro is {!}fmt (reformat the current paragraph). Programmers sometimes use it to run their code, or just portions of it, through indent or other code reformatting tools.

Using the :r! and ! commands means that any external utility or filter can be treated as an extension of our editor. I have occasionally used these with scripts that pulled data from a database, or with wget or lynx commands that pulled data off a website, or ssh commands that pulled data from remote systems.

Another useful ex command is :so (short for :source). This reads the contents of a file as a series of commands. When you start vi it normally, implicitly, performs a :source on ~/.exinitrc file (and Vim usually does this on ~/.vimrc, naturally enough). The use of this is that you can change your editor profile on the fly by simply sourcing in a new set of macros, abbreviations, and editor settings. If you're sneaky you can even use this as a trick for storing sequences of ex editing commands to apply to files on demand.

For example I have a seven line file (36 characters) which runs a file through wc, and inserts a C-style comment at the top of the file containing that word count data. I can apply that "macro" to a file by using a command like: vim +'so mymacro.ex' ./mytarget

(The + command line option to vi and Vim is normally used to start the editing session at a given line number. However it's a little known fact that one can follow the + by any valid ex command/expression, such as a "source" command as I've done here; for a simple example I have scripts which invoke: vi +'/foo/d|wq!' ~/.ssh/known_hosts to remove an entry from my SSH known hosts file non-interactively while I'm re-imaging a set of servers).

Usually it's far easier to write such "macros" using Perl, AWK, sed (which is, in fact, like grep a utility inspired by the ed command).

The @ command is probably the most obscure vi command. In occasionally teaching advanced systems administration courses for close to a decade I've met very few people who've ever used it. @ executes the contents of a register as if it were a vi or ex command.
Example: I often use: :r!locate ... to find some file on my system and read its name into my document. From there I delete any extraneous hits, leaving only the full path to the file I'm interested in. Rather than laboriously Tab-ing through each component of the path (or worse, if I happen to be stuck on a machine without Tab completion support in its copy of vi) I just use:

1. 0i:r (to turn the current line into a valid :r command),
2. "cdd (to delete the line into the "c" register) and
3. @c execute that command.

That's only 10 keystrokes (and the expression "cdd @c is effectively a finger macro for me, so I can type it almost as quickly as any common six letter word).

A sobering thought

I've only scratched to surface of vi's power and none of what I've described here is even part of the "improvements" for which vim is named! All of what I've described here should work on any old copy of vi from 20 or 30 years ago.

There are people who have used considerably more of vi's power than I ever will.

A persistence context handles a set of entities which hold data to be persisted in some persistence store (e.g. a database). In particular, the context is aware of the different states an entity can have (e.g. managed, detached) in relation to both the context and the underlying persistence store.

Although Hibernate-related (a JPA provider), I think these links are useful:

http://docs.jboss.org/hibernate/core/4.0/devguide/en-US/html/ch03.html

http://docs.jboss.org/hibernate/entitymanager/3.5/reference/en/html/architecture.html

In Java EE, a persistence context is normally accessed via an EntityManager.

http://docs.oracle.com/javaee/6/api/javax/persistence/EntityManager.html

The various states an entity can have and the transitions between these are described below:

As an alternative to 'save & quit', you can use git-commit's function git-commit-commit, by default bound to C-c C-c. It will save the file and close it. Afterwards, you still have to close emacs with C-x C-c, as mentioned before. I am currently trying to find out how to make emacs quit automatically.

MySQL DELETE records with JOIN

You generally use INNER JOIN in the SELECT statement to select records from a table that have corresponding records in other tables. We can also use the INNER JOIN clause with the DELETE statement to delete records from a table and also the corresponding records in other tables e.g., to delete records from both T1 and T2 tables that meet a particular condition, you use the following statement:

DELETE T1, T2
FROM T1
INNER JOIN T2 ON T1.key = T2.key
WHERE condition

Notice that you put table names T1 and T2 between DELETE and FROM. If you omit the T1 table, the DELETE statement only deletes records in the T2 table, and if you omit the T2 table, only records in the T1 table are deleted.

The join condition T1.key = T2.key specifies the corresponding records in the T2 table that need be deleted.

The condition in the WHERE clause specifies which records in the T1 and T2 that need to be deleted.

You can use the target argument in the Thread constructor to directly pass in a function that gets called instead of run.

Just one command did the work

netsh http add iplisten 127.0.0.1

function download(text, name, type) {_x000D_
  var a = document.getElementById("a");_x000D_
  var file = new Blob([text], {type: type});_x000D_
  a.href = URL.createObjectURL(file);_x000D_
  a.download = name;_x000D_
}

<a href="" id="a">click here to download your file</a>_x000D_
<button onclick="download('file text', 'myfilename.json', 'text/json')">Create file</button>

I think this can work with json files too if you change the mime type.

You should use the string replace function, with a single regex. Assuming by special characters, you mean anything that's not letter, here is a solution:

const str = "abc's test#s";_x000D_
console.log(str.replace(/[^a-zA-Z ]/g, ""));

From Django documentation for url

url(regex, view, kwargs=None, name=None) This function is an alias to django.urls.re_path(). It’s likely to be deprecated in a future release.

Key difference between path and re_path is that path uses route without regex

You can use re_path for complex regex calls and use just path for simpler lookups

You may have a table called 'test'

COPY test(gid, "name", the_geom)
FROM '/home/data/sample.csv'
WITH DELIMITER ','
CSV HEADER

cdecl is a great tool for deciphering weird syntax like function pointer declarations. You can use it to generate them as well.

As far as tips for making complicated declarations easier to parse for future maintenance (by yourself or others), I recommend making typedefs of small chunks and using those small pieces as building blocks for larger and more complicated expressions. For example:

typedef int (*FUNC_TYPE_1)(void);
typedef double (*FUNC_TYPE_2)(void);
typedef FUNC_TYPE_1 (*FUNC_TYPE_3)(FUNC_TYPE_2);

rather than:

typedef int (*(*FUNC_TYPE_3)(double (*)(void)))(void);

cdecl can help you out with this stuff:

cdecl> explain int (*FUNC_TYPE_1)(void)
declare FUNC_TYPE_1 as pointer to function (void) returning int
cdecl> explain double (*FUNC_TYPE_2)(void)
declare FUNC_TYPE_2 as pointer to function (void) returning double
cdecl> declare FUNC_TYPE_3 as pointer to function (pointer to function (void) returning double) returning pointer to function (void) returning int
int (*(*FUNC_TYPE_3)(double (*)(void )))(void )

And is (in fact) exactly how I generated that crazy mess above.

Using this and {{this}}. See code below in node.js:

var Handlebars= require("handlebars");
var randomList= ["James Bond", "Dr. No", "Octopussy", "Goldeneye"];
var source= "<ul>{{#each this}}<li>{{this}}</li>{{/each}}</ul>";
var template= Handlebars.compile(source);
console.log(template(randomList));

Console log output:

<ul><li>James Bond</li><li>Dr. No</li><li>Octopussy</li><li>Goldeneye</li></ul>

Standard (https://tools.ietf.org/html/rfc6750) says you can use:

• Form-Encoded Body Parameter: Authorization: Bearer mytoken123
• URI Query Parameter: access_token=mytoken123

So it's possible to pass many Bearer Token with URI, but doing this is discouraged (see section 5 in the standard).

Here is a solution that works with simple CSS and standard font awesome syntax, no need for unicode values, etc.

1. Create an <input> tag followed by a standard <i> tag with the icon you need.

2. Use relative positioning together with a higher layer order (z-index) and move the icon over and on top of the input field.

3. (Optional) You can make the icon active, to perhaps submit the data, via standard JS.

See the three code snippets below for the HTML / CSS / JS.

Create a custom Router with its own browserHistory:

import React from 'react';
import { Router } from 'react-router-dom';
import { createBrowserHistory } from 'history';

export const history = createBrowserHistory();

const ExtBrowserRouter = ({children}) => (
  <Router history={history} >
  { children }
  </Router>
);

export default ExtBrowserRouter

Next, on your Root where you define your Router, use the following:

import React from 'react';       
import { /*BrowserRouter,*/ Route, Switch, Redirect } from 'react-router-dom';

//Use 'ExtBrowserRouter' instead of 'BrowserRouter'
import ExtBrowserRouter from './ExtBrowserRouter'; 
...

export default class Root extends React.Component {
  render() {
    return (
      <Provider store={store}>
        <ExtBrowserRouter>
          <Switch>
            ...
            <Route path="/login" component={Login}  />
            ...
          </Switch>
        </ExtBrowserRouter>
      </Provider>
    )
  }
}

Finally, import history where you need it and use it:

import { history } from '../routers/ExtBrowserRouter';
...

export function logout(){
  clearTokens();      
  history.push('/login'); //WORKS AS EXPECTED!
  return Promise.reject('Refresh token has expired');
}

To find the minimum value of a list, you might just as well use min:

x = min(float(s) for s in l) # min of a generator

Or, if you want the result as a string, rather than a float, use a key function:

x = min(l, key=float)

For jQuery Mobile 1.4.5:

for anchor buttons, the CSS class is: ui-state-disabled, and for input buttons it is just enough to toggle the disabled attribute.

function toggleDisableButtons() {_x000D_
  $("#link-1").toggleClass("ui-state-disabled", !$("#link-1").hasClass("ui-state-disabled"));_x000D_
  $("#button-1").attr("disabled") ? $("#button-1").removeAttr("disabled") : $("#button-1").attr("disabled","");_x000D_
}

    <button class="ui-btn" onclick="toggleDisableButtons();">Toggle disabled</button>_x000D_
    <a id="link-1" href="#" class="ui-btn ui-state-disabled">Anchor</a>_x000D_

    _x000D_
  </div>_x000D_
</div>_x000D_
</body>_x000D_
</html>

BTW, for input buttons, there is an alternate method:

Enable:

$(".class").prop("disabled", false).removeClass("ui-state-disabled");

Disable:

$(".class").prop("disabled", true).addClass("ui-state-disabled");

If you want to log to STDOUT you can use any of the ways Laravel provides; for example (from wired00's answer):

Log::info('This is some useful information.');

The STDOUT magic can be done with the following (you are setting the file where info messages go):

Log::useFiles('php://stdout', 'info');

Word of caution: this is strictly for debugging. Do no use anything in production you don't fully understand.

You can make use of location service available in @angular/common and via this below code you can get the location or current URL

import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router';

@Component({
  selector: 'app-top-nav',
  templateUrl: './top-nav.component.html',
  styleUrls: ['./top-nav.component.scss']
})
export class TopNavComponent implements OnInit {

  route: string;

  constructor(location: Location, router: Router) {
    router.events.subscribe((val) => {
      if(location.path() != ''){
        this.route = location.path();
      } else {
        this.route = 'Home'
      }
    });
  }

  ngOnInit() {
  }

}

here is the reference link from where I have copied thing to get location for my project. https://github.com/elliotforbes/angular-2-admin/blob/master/src/app/common/top-nav/top-nav.component.ts

I'd recommend to use an array for storing all values via __set().

class foo {

    protected $values = array();

    public function __get( $key )
    {
        return $this->values[ $key ];
    }

    public function __set( $key, $value )
    {
        $this->values[ $key ] = $value;
    }

}

This way you make sure, that you can't access the variables in another way (note that $values is protected), to avoid collisions.

    val fileName = "app.apk"
    ZipFile(fileName).use { zip ->
        zip.entries().asSequence().forEach { entry ->
            if(entry.name == "AndroidManifest.xml") {
                zip.getInputStream(entry).use { input ->

This is a kotlin version of the answer above.

It's a default font on Macs, but rare on PCs. Since it's not technically web-safe, some people may have it and some people may not. If you want to use a font like that, without using @font-face, you may want to write it out several different ways because it might not work the same for everyone.

I like using a font stack that touches on all bases like this:

font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", 
  Helvetica, Arial, "Lucida Grande", sans-serif;

This recommended font-family stack is further described in this CSS-Tricks snippet Better Helvetica which uses a font-weight: 300; as well.

The data.table package introduced the IDate class some time ago and zoo-package-like functions to retrieve months, days, etc (Check ?IDate). so, you can extract the desired info now in the following ways:

require(data.table)
df <- data.frame(id = 1:3,
                 date = c("2004-02-06" , "2006-03-14" , "2007-07-16"))
setDT(df)
df[ , date := as.IDate(date) ] # instead of as.Date()
df[ , yrmn := paste0(year(date), '-', month(date)) ]
df[ , yrmn2 := format(date, '%Y-%m') ]

If you want to wait for jobs to finish, use wait. This will make the shell wait until all background jobs complete. However, if any of your jobs daemonize themselves, they are no longer children of the shell and wait will have no effect (as far as the shell is concerned, the child is already done. Indeed, when a process daemonizes itself, it does so by terminating and spawning a new process that inherits its role).

#!/bin/sh
{ sleep 5; echo waking up after 5 seconds; } &
{ sleep 1; echo waking up after 1 second; } &
wait
echo all jobs are done!

You can use SELECT EXISTS command and execute it for a cursor using a rawQuery, from the documentation

The EXISTS operator always evaluates to one of the integer values 0 and 1. If executing the SELECT statement specified as the right-hand operand of the EXISTS operator would return one or more rows, then the EXISTS operator evaluates to 1. If executing the SELECT would return no rows at all, then the EXISTS operator evaluates to 0.

Although not exactly answering the question as formulated, but if you need or can take the end result as string you can also use

string s = Char.ConvertFromUtf32(56);

which will give you surrogate UTF-16 pairs if needed, protecting you if you are out side of the BMP.

From kitkat onwards use evaluateJavascript method instead loadUrl to call the javascript functions like below

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
        webView.evaluateJavascript("enable();", null);
    } else {
        webView.loadUrl("javascript:enable();");
    }

If you want to delete rows based on multiple values of the column, you could use:

df[(df.line_race != 0) & (df.line_race != 10)]

To drop all rows with values 0 and 10 for line_race.

new table inherits only "not null" constraint and no other constraint. Thus you can alter the table after creating it with "create table as" command or you can define all constraint that you need by following the

create table t1 (id number default 1 not null);
insert into t1 (id) values (2);

create table t2 as select * from t1;

This will create table t2 with not null constraint. But for some other constraint except "not null" you should use the following syntax

create table t1 (id number default 1 unique);
insert into t1 (id) values (2);

create table t2 (id default 1 unique)
as select * from t1;

Laravel 5 ships with a Bootstrap 4 paginator if anyone needs it.

First create a new service provider.

php artisan make:provider PaginationServiceProvider

In the register method pass a closure to Laravel's paginator class that creates and returns the new presenter.

<?php


namespace App\Providers;

use Illuminate\Pagination\BootstrapFourPresenter;
use Illuminate\Pagination\Paginator;
use Illuminate\Support\ServiceProvider;

class PaginationServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        Paginator::presenter(function($paginator)
        {
            return new BootstrapFourPresenter($paginator);
        });
    }
}

Register the new provider in config/app.php

'providers' => [
    //....
    App\Providers\PaginationServiceProvider::class,
]

msys2@bash:~$ adb shell 'su -c id'
uid=0(root) gid=0(root) groups=0(root) context=u:r:magisk:s0
msys2@bash:~$ adb shell "su -c id"
uid=0(root) gid=0(root) groups=0(root) context=u:r:magisk:s0
msys2@bash:~$ adb shell su -c id
uid=0(root) gid=0(root) groups=0(root) context=u:r:magisk:s0

2. adb shell -t

if want run am cmd, -t option maybe required:

C:\>adb shell su -c am stack list
cmd: Failure calling service activity: Failed transaction (2147483646)

C:\>adb shell -t su -c am stack list
Stack id=0 bounds=[0,0][1200,1920] displayId=0 userId=0
...

If you're looking for something quick and dirty just load the data in the head of your HTML document.

data.js

var DATA = {"a" : "b", "c" : "d"};

index.html

<html>
<head>
   <script src="data.js" ></script>
   <script src="main.js" ></script>
</head>
...
</html>

main.js

(function(){
   console.log(DATA); // {"a" : "b", "c" : "d"}
})();

I should mention that your heap size (in Chrome) is about 4GBs, so if your data is larger than that you should find another method. If you want to check another browser try this:

window.performance.memory.jsHeapSizeLimit / 1024 / 1024 / 1024 + " GBs"
// "4.046875 GBs"
