Read open as

open for inheritance in other modules

I repeat open for inheritance in other modules. So an open class is open for subclassing in other modules that include the defining module. Open vars and functions are open for overriding in other modules. Its the least restrictive access level. It is as good as public access except that something that is public is closed for inheritance in other modules.

From Apple Docs:

Open access applies only to classes and class members, and it differs from public access as follows:

1. Classes with public access, or any more restrictive access level, can be subclassed only within the module where they’re defined.

2. Class members with public access, or any more restrictive access level, can be overridden by subclasses only within the module where they’re defined.

3. Open classes can be subclassed within the module where they’re defined, and within any module that imports the module where they’re defined.

4. Open class members can be overridden by subclasses within the module where they’re defined, and within any module that imports the module where they’re defined.

The import allows the java programmer to access classes of a package without package qualification.

The static import feature allows to access the static members of a class without the class qualification.

The import provides accessibility to classes and interface whereas static import provides accessibility to static members of the class.

Example :

With import

import java.lang.System.*;    
class StaticImportExample{  
    public static void main(String args[]){  

       System.out.println("Hello");
       System.out.println("Java");  

  }   
} 

With static import

import static java.lang.System.*;    
class StaticImportExample{  
  public static void main(String args[]){  

   out.println("Hello");//Now no need of System.out  
   out.println("Java");  

 }   
}

volatile and transient keywords

1) transient keyword is used along with instance variables to exclude them from serialization process. If a field is transient its value will not be persisted.

On the other hand, volatile keyword is used to mark a Java variable as "being stored in main memory".

Every read of a volatile variable will be read from the computer's main memory, and not from the CPU cache, and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.

2) transient keyword cannot be used along with static keyword but volatile can be used along with static.

3) transient variables are initialized with default value during de-serialization and there assignment or restoration of value has to be handled by application code.

For more information, see my blog:
http://javaexplorer03.blogspot.in/2015/07/difference-between-volatile-and.html

You can set one of the columns as an index in case it is an "id" for example. In this case the index column will be replaced by one of the columns you have chosen.

df.set_index('id', inplace=True)

There is no str accessor for datetimes and you can't do dates.astype(str) either, you can call apply and use datetime.strftime:

In [73]:

dates = pd.to_datetime(pd.Series(['20010101', '20010331']), format = '%Y%m%d')
dates.apply(lambda x: x.strftime('%Y-%m-%d'))
Out[73]:
0    2001-01-01
1    2001-03-31
dtype: object

You can change the format of your date strings using whatever you like: strftime() and strptime() Behavior.

Update

As of version 0.17.0 you can do this using dt.strftime

dates.dt.strftime('%Y-%m-%d')

will now work

You can also use Comparator.comparing(Function, Comparator)
It is convenient to chain comparators when necessary, e.g.:

Comparator<SomeEntity> ENTITY_COMPARATOR = comparing(SomeEntity::getProperty1, reverseOrder())
        .thenComparingInt(SomeEntity::getProperty2)
        .thenComparing(SomeEntity::getProperty3, reverseOrder());

Table relationship vs. entity relationship

In a relational database system, a one-to-many table relationship looks as follows:

Note that the relationship is based on the Foreign Key column (e.g., post_id) in the child table.

So, there is a single source of truth when it comes to managing a one-to-many table relationship.

Now, if you take a bidirectional entity relationship that maps on the one-to-many table relationship we saw previously:

If you take a look at the diagram above, you can see that there are two ways to manage this relationship.

In the Post entity, you have the comments collection:

@OneToMany(
    mappedBy = "post",
    cascade = CascadeType.ALL,
    orphanRemoval = true
)
private List<PostComment> comments = new ArrayList<>();

And, in the PostComment, the post association is mapped as follows:

@ManyToOne(
    fetch = FetchType.LAZY
)
@JoinColumn(name = "post_id")
private Post post;

Because there are two ways to represent the Foreign Key column, you must define which is the source of truth when it comes to translating the association state change into its equivalent Foreign Key column value modification.

MappedBy

The mappedBy attribute tells that the @ManyToOne side is in charge of managing the Foreign Key column, and the collection is used only to fetch the child entities and to cascade parent entity state changes to children (e.g., removing the parent should also remove the child entities).

Synchronize both sides of a bidirectional association

Now, even if you defined the mappedBy attribute and the child-side @ManyToOne association manages the Foreign Key column, you still need to synchronize both sides of the bidirectional association.

The best way to do that is to add these two utility methods:

public void addComment(PostComment comment) {
    comments.add(comment);
    comment.setPost(this);
}

public void removeComment(PostComment comment) {
    comments.remove(comment);
    comment.setPost(null);
}

The addComment and removeComment methods ensure that both sides are synchronized. So, if we add a child entity, the child entity needs to point to the parent and the parent entity should have the child contained in the child collection.

Try this

$("#abc").html('<span class = "xyz"> SAMPLE TEXT</span>');

Handle all the css relevant to that span within xyz

I search a way to map a many-to-many association table with extra column(s) with hibernate in xml files configuration.

Assuming with have two table 'a' & 'c' with a many to many association with a column named 'extra'. Cause I didn't find any complete example, here is my code. Hope it will help :).

First here is the Java objects.

public class A implements Serializable{  

    protected int id;
    // put some others fields if needed ...   
    private Set<AC> ac = new HashSet<AC>();

    public A(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Set<AC> getAC() {
        return ac;
    }

    public void setAC(Set<AC> ac) {
        this.ac = ac;
    }

    /** {@inheritDoc} */
    @Override
    public int hashCode() {
        final int prime = 97;
        int result = 1;
        result = prime * result + id;
        return result;
    }

    /** {@inheritDoc} */
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (!(obj instanceof A))
            return false;
        final A other = (A) obj;
        if (id != other.getId())
            return false;
        return true;
    }

}

public class C implements Serializable{

    protected int id;
    // put some others fields if needed ...    

    public C(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    /** {@inheritDoc} */
    @Override
    public int hashCode() {
        final int prime = 98;
        int result = 1;
        result = prime * result + id;
        return result;
    }

    /** {@inheritDoc} */
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (!(obj instanceof C))
            return false;
        final C other = (C) obj;
        if (id != other.getId())
            return false;
        return true;
    }

}

Now, we have to create the association table. The first step is to create an object representing a complex primary key (a.id, c.id).

public class ACId implements Serializable{

    private A a;
    private C c;

    public ACId() {
        super();
    }

    public A getA() {
        return a;
    }
    public void setA(A a) {
        this.a = a;
    }
    public C getC() {
        return c;
    }
    public void setC(C c) {
        this.c = c;
    }
    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((a == null) ? 0 : a.hashCode());
        result = prime * result
                + ((c == null) ? 0 : c.hashCode());
        return result;
    }
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        ACId other = (ACId) obj;
        if (a == null) {
            if (other.a != null)
                return false;
        } else if (!a.equals(other.a))
            return false;
        if (c == null) {
            if (other.c != null)
                return false;
        } else if (!c.equals(other.c))
            return false;
        return true;
    }
}

Now let's create the association object itself.

public class AC implements java.io.Serializable{

    private ACId id = new ACId();
    private String extra;

    public AC(){

    }

    public ACId getId() {
        return id;
    }

    public void setId(ACId id) {
        this.id = id;
    }

    public A getA(){
        return getId().getA();
    }

    public C getC(){
        return getId().getC();
    }

    public void setC(C C){
        getId().setC(C);
    }

    public void setA(A A){
        getId().setA(A);
    }

    public String getExtra() {
        return extra;
    }

    public void setExtra(String extra) {
        this.extra = extra;
    }

    public boolean equals(Object o) {
        if (this == o)
            return true;
        if (o == null || getClass() != o.getClass())
            return false;

        AC that = (AC) o;

        if (getId() != null ? !getId().equals(that.getId())
                : that.getId() != null)
            return false;

        return true;
    }

    public int hashCode() {
        return (getId() != null ? getId().hashCode() : 0);
    }
}

At this point, it's time to map all our classes with hibernate xml configuration.

A.hbm.xml and C.hxml.xml (quiete the same).

<class name="A" table="a">
        <id name="id" column="id_a" unsaved-value="0">
            <generator class="identity">
                <param name="sequence">a_id_seq</param>
            </generator>
        </id>
<!-- here you should map all others table columns -->
<!-- <property name="otherprop" column="otherprop" type="string" access="field" /> -->
    <set name="ac" table="a_c" lazy="true" access="field" fetch="select" cascade="all">
        <key>
            <column name="id_a" not-null="true" />
        </key>
        <one-to-many class="AC" />
    </set>
</class>

<class name="C" table="c">
        <id name="id" column="id_c" unsaved-value="0">
            <generator class="identity">
                <param name="sequence">c_id_seq</param>
            </generator>
        </id>
</class>

And then association mapping file, a_c.hbm.xml.

<class name="AC" table="a_c">
    <composite-id name="id" class="ACId">
        <key-many-to-one name="a" class="A" column="id_a" />
        <key-many-to-one name="c" class="C" column="id_c" />
    </composite-id>
    <property name="extra" type="string" column="extra" />
</class>

Here is the code sample to test.

A = ADao.get(1);
C = CDao.get(1);

if(A != null && C != null){
    boolean exists = false;
            // just check if it's updated or not
    for(AC a : a.getAC()){
        if(a.getC().equals(c)){
            // update field
            a.setExtra("extra updated");
            exists = true;
            break;
        }
    }

    // add 
    if(!exists){
        ACId idAC = new ACId();
        idAC.setA(a);
        idAC.setC(c);

        AC AC = new AC();
        AC.setId(idAC);
        AC.setExtra("extra added"); 
        a.getAC().add(AC);
    }

    ADao.save(A);
}

Each Java process has a pid, which you first need to find with the jps command.

Once you have the pid, you can use jstat -gc [insert-pid-here] to find statistics of the behavior of the garbage collected heap.

• jstat -gccapacity [insert-pid-here] will present information about memory pool generation and space capabilities.

• jstat -gcutil [insert-pid-here] will present the utilization of each generation as a percentage of its capacity. Useful to get an at a glance view of usage.

See jstat docs on Oracle's site.

Last month I tried to configure iptables on a LXC VM container, but every time after reboot the iptables configuration was not automatically loaded.

The only way for me to get it working was by running the following command:

yum -y install iptables-services; systemctl disable firewalld; systemctl mask firewalld; service iptables restart; service iptables save

open C:\myfile.txt for append as #1
write #1, text1.text, text2.text
close()

This is the code I use in Visual Basic 6.0. It helps me to create a txt file on my drive, write two pieces of data into it, and then close the file... Give it a try...

When you are in android studio 3 or above you need to add following lines AndroidManifest.xml file

<activity
            android:name=".MainActivity"
            android:configChanges="orientation"
            android:screenOrientation= "sensorLandscape"
            tools:ignore="LockedOrientationActivity">

One thing this is sensor Landscape, means it will work on both landscape sides

But if you only want to work the regular landscape side then, replace sensorLandscape to landscape

What i have done is that import a new project into eclipse workspace, and that path of that was be

android-sdk-macosx/extras/google/google_play_services/libproject/google-play-services_lib

and add as library in your project.. that it .. simple!! you might require to add support library in your project.

The -std=c++14 flag is not supported on GCC 4.8. If you want to use C++14 features you need to compile with -std=c++1y. Using godbolt.org it appears that the earilest version to support -std=c++14 is GCC 4.9.0 or Clang 3.5.0

In about:config add content.cors.disable (empty string).

My solution to this problem was to use the $() sub-expression block.

Add-Type -Language CSharp @"
public class Thing{
    public string Name;
}
"@;

$x = New-Object Thing

$x.Name = "Bill"

Write-Output "My name is $($x.Name)"
Write-Output "This won't work right: $x.Name"

Gives:

My name is Bill
This won't work right: Thing.Name

Building off of Nike's answer. Its straightforward to implement the laplacian based method with opencv:

short GetSharpness(char* data, unsigned int width, unsigned int height)
{
    // assumes that your image is already in planner yuv or 8 bit greyscale
    IplImage* in = cvCreateImage(cvSize(width,height),IPL_DEPTH_8U,1);
    IplImage* out = cvCreateImage(cvSize(width,height),IPL_DEPTH_16S,1);
    memcpy(in->imageData,data,width*height);

    // aperture size of 1 corresponds to the correct matrix
    cvLaplace(in, out, 1);

    short maxLap = -32767;
    short* imgData = (short*)out->imageData;
    for(int i =0;i<(out->imageSize/2);i++)
    {
        if(imgData[i] > maxLap) maxLap = imgData[i];
    }

    cvReleaseImage(&in);
    cvReleaseImage(&out);
    return maxLap;
}

Will return a short indicating the maximum sharpness detected, which based on my tests on real world samples, is a pretty good indicator of if a camera is in focus or not. Not surprisingly, normal values are scene dependent but much less so than the FFT method which has to high of a false positive rate to be useful in my application.

Let me quote and comment more closely the RFC 7231 section 4.2.2, already cited in earlier comments :

A request method is considered "idempotent" if the intended effect on the server of multiple identical requests with that method is the same as the effect for a single such request. Of the request methods defined by this specification, PUT, DELETE, and safe request methods are idempotent.

(...)

Idempotent methods are distinguished because the request can be repeated automatically if a communication failure occurs before the client is able to read the server's response. For example, if a client sends a PUT request and the underlying connection is closed before any response is received, then the client can establish a new connection and retry the idempotent request. It knows that repeating the request will have the same intended effect, even if the original request succeeded, though the response might differ.

So, what should be "the same" after a repeated request of an idempotent method? Not the server state, nor the server response, but the intended effect. In particular, the method should be idempotent "from the point of view of the client". Now, I think that this point of view shows that the last example in Dan Lowe's answer, which I don't want to plagiarize here, indeed shows that a PATCH request can be non-idempotent (in a more natural way than the example in Jason Hoetger's answer).

Indeed, let's make the example slightly more precise by making explicit one possible intend for the first client. Let's say that this client goes through the list of users with the project to check their emails and zip codes. He starts with user 1, notices that the zip is right but the email is wrong. He decides to correct this with a PATCH request, which is fully legitimate, and sends only

PATCH /users/1
{"email": "[email protected]"}

since this is the only correction. Now, the request fails because of some network issue and is re-submitted automatically a couple of hours later. In the meanwhile, another client has (erroneously) modified the zip of user 1. Then, sending the same PATCH request a second time does not achieve the intended effect of the client, since we end up with an incorrect zip. Hence the method is not idempotent in the sense of the RFC.

If instead the client uses a PUT request to correct the email, sending to the server all properties of user 1 along with the email, his intended effect will be achieved even if the request has to be re-sent later and user 1 has been modified in the meanwhile --- since the second PUT request will overwrite all changes since the first request.

Q1) Here are couple things to read or google more :

Main differences between SOAP and RESTful web services in java http://www.ajaxonomy.com/2008/xml/web-services-part-1-soap-vs-rest

It's up to you what do you want to learn first. I'd recommend you take a look at the CXF framework. You can build both rest/soap services.

Q2) Here are couple of good tutorials for soap (I had them bookmarked) :

http://united-coders.com/phillip-steffensen/developing-a-simple-soap-webservice-using-spring-301-and-apache-cxf-226

http://www.benmccann.com/blog/web-services-tutorial-with-apache-cxf/

http://www.mastertheboss.com/web-interfaces/337-apache-cxf-interceptors.html

Best way to learn is not just reading tutorials. But you would first go trough tutorials to get a basic idea so you can see that you're able to produce something(or not) and that would get you motivated.

SO is great way to learn particular technology (or more), people ask lot of wierd questions, and there are ever weirder answers. But overall you'll learn about ways to solve issues on other way. Maybe you didn't know of that way, maybe you couldn't thought of it by yourself.

Subscribe to couple of tags that are interesting to you and be persistent, ask good questions and try to give good answers and I guarantee you that you'll learn this as time passes (if you're persistent that is).

Q3) You will have to answer this one yourself. First by deciding what you're going to build, after all you will need to think of some mini project or something and take it from there.

If you decide to use CXF as your framework for building either REST/SOAP services I'd recommend you look up this book Apache CXF Web Service Development. It's fantastic, not hard to read and not too big either (win win).

Arrays are special objects in java, they have a simple attribute named length which is final.

There is no "class definition" of an array (you can't find it in any .class file), they're a part of the language itself.

10.7. Array Members

The members of an array type are all of the following:

• The public final field length, which contains the number of components of the array. length may be positive or zero.

• The public method clone, which overrides the method of the same name in class Object and throws no checked exceptions. The return type of the clone method of an array type T[] is T[].

  A clone of a multidimensional array is shallow, which is to say that it creates only a single new array. Subarrays are shared.

• All the members inherited from class Object; the only method of Object that is not inherited is its clone method.

Use the Chart Wizard.

On Step 2 of 4, there is a tab labeled "Series". There are 3 fields and a list box on this tab. The list box shows the different series you are already including on the chart. Each series has both a "Name" field and a "Values" field that is specific to that series. The final field is the "Category (X) axis labels" field, which is common to all series.

Click on the "Add" button below the list box. This will add a blank series to your list box. Notice that the values for "Name" and for "Values" change when you highlight a series in the list box.

Select your new series.

There is an icon in each field on the right side. This icon allows you to select cells in the workbook to pull the data from. When you click it, the Wizard temporarily hides itself (except for the field you are working in) allowing you to interact with the workbook.

Select the appropriate sheet in the workbook and then select the fields with the data you want to show in the chart. The button on the right of the field can be clicked to unhide the wizard.

Hope that helps.

EDIT: The above applies to 2003 and before. For 2007, when the chart is selected, you should be able to do a similar action using the "Select Data" option on the "Design" tab of the ribbon. This opens up a dialog box listing the Series for the chart. You can select the series just as you could in Excel 2003, but you must use the "Add" and "Edit" buttons to define custom series.

In the component.css or app.css add Icon Color styles

.material-icons.color_green { color: #00FF00; }
.material-icons.color_white { color: #FFFFFF; }

In the component.html set the icon class

<mat-icon class="material-icons color_green">games</mat-icon>

You can configure log4j.properties like above answers, or use org.apache.log4j.BasicConfigurator

public class FooImpl implements Foo {

    private static final Logger LOGGER = Logger.getLogger(FooBar.class);

    public Object createObject() {
        BasicConfigurator.configure();
        LOGGER.info("something");
        return new Object();
    }
}

So under the table, configure do:

  configure() {
    Logger root = Logger.getRootLogger();
    root.addAppender(new ConsoleAppender(
           new PatternLayout(PatternLayout.TTCC_CONVERSION_PATTERN)));
  }

Here is an alternative solution:

class extendedWebBrowser : WebBrowser
{
    /// <summary>
    /// Default constructor which will make the browser to ignore all errors
    /// </summary>
    public extendedWebBrowser()
    {
        this.ScriptErrorsSuppressed = true;

        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
             object axIWebBrowser2 = field.GetValue(this);
             axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { true });
        }
    }
}

According to the documentation.

Looks like the answers above are for when you are writing and compiling a program, but I'm using a Vendor's software, Catalog.exe, part of the Voyager card catalog by "Ex Libris" and I'm getting the error as well:

catalog-error.png http://img805.imageshack.us/img805/8275/catalogerror.png

I have two Windows 7 32-bit machines. The newer one is giving me the error but on the older one it runs fine. I have done a lot of research with Google and here are some of the things I've found that people are saying related to this issue. Maybe one of these things will help fix the error for you, although they didn't work for me:

• An outdated or corrupt video card driver can cause Run-Time Error 380 (try updating)
• Restart in Safe Mode
• Run system file checker sfc /scannow
• Run the application as Administrator (right click, Run as Administrator)
• Get all the MS Windows and MS Office Updates
• Uninstall and reinstall the software
• Clean the registry with CCleaner to remove bad or null registry values
• Reinstall MS Office (or possibly install and older version?)
• (Re) install all the Microsoft VB6 runtime libraries, updates, and service packs
• (Re) install the "Microsoft Visual C++ Runtime Library"
• Configure Windows to use the decimal "." when displaying numbers. Select Start / Control Panel / Date, Time, Language, and Regional Options.

From what others are saying (like David M) I think it could be related to the MSVBM60.DLL library - but it appears that on both of my computers this file is the exact same (same version, size, date, etc).

Since that file wasn't different I tried to find what other (dll) files the application could be using, so I launched Process Explorer by Sysinternals and took a look at the application (it loads and then crashes when you tell it to "connect"), and the screenshots below are what I found.

Now, I'm not a Windows / VB programmer, just a power user, and so I'm about at the end of my knowledge for what to do. I've talked to the software vendor and they recommend reinstalling Windows. That will probably work, but it just bugs me that this program can run on Windows 7, but something on this particular system is causing errors. Finally, this is an image that has been deployed on multiple machines already and so while re-installing Windows once is not a big deal it would save me some serious time if I could figure out a fix or workaround.

Here is a helpful website on using appcmd to export/import a site configuration. http://www.microsoftpro.nl/2011/01/27/exporting-and-importing-sites-and-app-pools-from-iis-7-and-7-5/

What about creating an extension method?

public static class NullableExtensions
{
    public static bool TryParse(this DateTime? dateTime, string dateString, out DateTime? result)
    {
        DateTime tempDate;
        if(! DateTime.TryParse(dateString,out tempDate))
        {
            result = null;
            return false;
        }

        result = tempDate;
        return true;

    }
}

DECLARE @nombre NVARCHAR(100)
DECLARE @tablas TABLE(nombre nvarchar(100))

INSERT INTO @tablas
SELECT t.TABLE_SCHEMA+ '.'+t.TABLE_NAME FROM INFORMATION_SCHEMA.TABLES T
DECLARE @contador INT=0

SELECT @contador=COUNT(*) FROM INFORMATION_SCHEMA.TABLES

WHILE @contador>0 
BEGIN
    SELECT TOP 1 @nombre=nombre FROM @tablas 
    DECLARE @sql NVARCHAR(500)=''
    SET @sql =@sql+'Truncate table  '+@nombre
    EXEC (@sql)
    SELECT @sql
    SET @contador=@contador-1   
    DELETE TOP (1) @tablas 
END

Sounds like an ideal application for RegEx -- an engine designed for fast text manipulation. In this case:

Regex.Replace("He\"ll,o Wo'r.ld", "[@,\\.\";'\\\\]", string.Empty)

Update for everybody coming to check why tensorflow.keras is not visible in PyCharm.

Starting from TensorFlow 2.0, only PyCharm versions > 2019.3 are able to recognise tensorflow and keras inside tensorflow (tensorflow.keras) properly.

Also, it is recommended(by Francois Chollet) that everybody switches to tensorflow.keras in place of plain keras.

Add this to your base controller inside GetDefaults() method

    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
         GetDefaults();
         base.OnActionExecuting(filterContext);
    }

    private void GetDefaults()
    {
    var actionName = filterContext.ActionDescriptor.ActionName;
    var controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;
    }

Implement your controllers to Basecontroller

Add a partial view _Breadcrumb.cshtml and add it in all required pages with @Html.Partial("_Breadcrumb")

_Breadcrumb.cshtml

<span>
    <a href="../@ViewData["controllerName"]">
        @ViewData["controllerName"]
    </a> > @ViewData["actionName"]
</span>

Try the maven-exec-plugin. From there:

mvn exec:java -Dexec.mainClass="com.example.Main"

This will run your class in the JVM. You can use -Dexec.args="arg0 arg1" to pass arguments.

If you're on Windows, apply quotes for exec.mainClass and exec.args:

mvn exec:java -D"exec.mainClass"="com.example.Main"

If you're doing this regularly, you can add the parameters into the pom.xml as well:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.2.1</version>
  <executions>
    <execution>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>com.example.Main</mainClass>
    <arguments>
      <argument>foo</argument>
      <argument>bar</argument>
    </arguments>
  </configuration>
</plugin>

Functions dealing with text like label, title, etc. accept parameters same as matplotlib.text.Text. For the font size you can use size/fontsize:

from matplotlib import pyplot as plt    

fig = plt.figure()
plt.plot(data)
fig.suptitle('test title', fontsize=20)
plt.xlabel('xlabel', fontsize=18)
plt.ylabel('ylabel', fontsize=16)
fig.savefig('test.jpg')

For globally setting title and label sizes, mpl.rcParams contains axes.titlesize and axes.labelsize. (From the page):

axes.titlesize      : large   # fontsize of the axes title
axes.labelsize      : medium  # fontsize of the x any y labels

(As far as I can see, there is no way to set x and y label sizes separately.)

And I see that axes.titlesize does not affect suptitle. I guess, you need to set that manually.

You can use the format method of the DateTime class:

$date = new DateTime('2000-01-01');
$result = $date->format('Y-m-d H:i:s');

If format fails for some reason, it will return FALSE. In some applications, it might make sense to handle the failing case:

if ($result) {
  echo $result;
} else { // format failed
  echo "Unknown Time";
}

Add this attribute:

checked="checked"

I like the answer that attempts to do the translate, however, while using the code it doesn't like columns that are not VARCHAR type such as BIGINT or DATETIME. I needed something similar today so I took the time to modify it more to my liking. It is also now encapsulated in a function which is the closest thing I could find to just typing describe as oracle handles it. I may still be missing a few data types in my case statement but this works for everything I tried it on. It also orders by ordinal position. this could be expanded on to include primary key columns easily as well.

CREATE FUNCTION dbo.describe (@TABLENAME varchar(50))
returns table
as
RETURN
(
SELECT TOP 1000 column_name AS [ColumnName],
       IS_NULLABLE AS [IsNullable],
       DATA_TYPE + '(' + CASE 
                                    WHEN DATA_TYPE = 'varchar' or DATA_TYPE = 'char' THEN 
                                      CASE 
                                        WHEN Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5)) = -1 THEN 'Max'
                                        ELSE Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5))
                                      END
                                    WHEN DATA_TYPE = 'decimal' or DATA_TYPE = 'numeric' THEN
                                      Cast(NUMERIC_PRECISION AS VARCHAR(5))+', '+Cast(NUMERIC_SCALE AS VARCHAR(5))
                                    WHEN DATA_TYPE = 'bigint' or DATA_TYPE = 'int' THEN
                                      Cast(NUMERIC_PRECISION AS VARCHAR(5))
                                    ELSE ''
                                  END + ')' AS [DataType]
FROM   INFORMATION_SCHEMA.Columns
WHERE  table_name = @TABLENAME
order by ordinal_Position
);
GO

once you create the function here is a sample table that I used

create table dbo.yourtable
(columna bigint,
 columnb int,
 columnc datetime,
 columnd varchar(100),
 columne char(10),
 columnf bit,
 columng numeric(10,2),
 columnh decimal(10,2)
 )

Then you can execute it as follows

select * from describe ('yourtable')

It returns the following

ColumnName IsNullable DataType

columna NO bigint(19)
columnb NO int(10)
columnc NO datetime()
columnd NO varchar(100)
columne NO char(10)
columnf NO bit()
columng NO numeric(10, 2)
columnh NO decimal(10, 2)

hope this helps someone.

For some applications you can use Fraction instead of floating-point numbers.

>>> from fractions import Fraction
>>> Fraction(1, 3**54)
Fraction(1, 58149737003040059690390169)

(For other applications, there's decimal, as suggested out by the other responses.)

You can do (jQuery 1.6 onwards):

$('#idCheckbox').prop('checked', true);
$('#idCheckbox').prop('checked', false);

to remove you can also use:

$('#idCheckbox').removeProp('checked');

with jQuery < 1.6 you must do

$('#idCheckbox').attr('checked', true);
$('#idCheckbox').removeAttr('checked');

As @Bruno suggested, using pytest fixtures is another solution that is accessible for both test classes or even just simple test functions. Here's an example testing python2.7 functions:

import pytest

@pytest.fixture(scope='function')
def some_resource(request):
    stuff_i_setup = ["I setup"]

    def some_teardown():
        stuff_i_setup[0] += " ... but now I'm torn down..."
        print stuff_i_setup[0]
    request.addfinalizer(some_teardown)

    return stuff_i_setup[0]

def test_1_that_needs_resource(some_resource):
    print some_resource + "... and now I'm testing things..."

So, running test_1... produces:

I setup... and now I'm testing things...
I setup ... but now I'm torn down...

Notice that stuff_i_setup is referenced in the fixture, allowing that object to be setup and torn down for the test it's interacting with. You can imagine this could be useful for a persistent object, such as a hypothetical database or some connection, that must be cleared before each test runs to keep them isolated.

Where it is documented:

From the API documentation under the has_many association in "Module ActiveRecord::Associations::ClassMethods"

collection.build(attributes = {}, …) Returns one or more new objects of the collection type that have been instantiated with attributes and linked to this object through a foreign key, but have not yet been saved. Note: This only works if an associated object already exists, not if it‘s nil!

The answer to building in the opposite direction is a slightly altered syntax. In your example with the dogs,

Class Dog
   has_many :tags
   belongs_to :person
end

Class Person
  has_many :dogs
end

d = Dog.new
d.build_person(:attributes => "go", :here => "like normal")

or even

t = Tag.new
t.build_dog(:name => "Rover", :breed => "Maltese")

You can also use create_dog to have it saved instantly (much like the corresponding "create" method you can call on the collection)

How is rails smart enough? It's magic (or more accurately, I just don't know, would love to find out!)

Here is the simple explanation of Redux over Flux. Redux does not have a dispatcher.It relies on pure functions called reducers. It does not need a dispatcher. Each actions are handled by one or more reducers to update the single store. Since data is immutable, reducers returns a new updated state that updates the store

For more information Flux vs Redux

I would like to add that Using the library momentjs in javascript you can have the whole data information in an object with:

const today = moment(1557697070824.94).toObject();

You should obtain an object with this properties:

today: {
  date: 15,
  hours: 2,
  milliseconds: 207,
  minutes: 31,
  months: 4
  seconds: 22,
  years: 2019
}

It is very useful when you have to calculate dates.

try this

 $('html').click(function() {
 //your stuf
 });

 $('#menucontainer').click(function(event){
     event.stopPropagation();
 });

you can also use the outside events

Sometimes swift file are not added or removed from target, go to target-->Build setting --> compile Sources --> see if any required swift class file is missing or not . In my case Application was crashing due to swift source file not present in compile.

With Java 8, you can do this.

final int[] arr = {1, 2, 3};
final PrimitiveIterator.OfInt i1 = Arrays.stream(arr).iterator();
final PrimitiveIterator.OfInt i2 = IntStream.of(arr).iterator();
final Iterator<Integer> i3 = IntStream.of(arr).boxed().iterator();

I recommend 2 things. First is associative array.

$person = Array();
$person['name'] = "Joe";
$person['age'] = 22;

Second is classes.

Detailed documentation here: http://php.net/manual/en/language.oop5.php

There is something explained here :

If the application is not doing anything in that 10 seconds, this will form a bad design only to make the user wait for 10 seconds doing nothing.

If there is something going on in that, or if you wish to implement 10 seconds delay splash screen,Here is the Code :

ProgressDialog pd;
pd = ProgressDialog.show(this,"Please Wait...", "Loading Application..", false, true);
pd.setCanceledOnTouchOutside(false);
Thread t = new Thread()
{ 
      @Override
      public void run()
      {
                try
                {
                    sleep(10000)  //Delay of 10 seconds
                } 
        catch (Exception e) {}
        handler.sendEmptyMessage(0);
        }
} ;
t.start();

//Handles the thread result of the Backup being executed.
private Handler handler = new Handler()
{
    @Override
    public void handleMessage(Message msg) 
    {
        pd.dismiss();
        //Start the Next Activity here...

    }
};

You're trying to insert $newdate into your db. You need to convert it to a string first. Use the DateTime::format method to convert back to a string.

To create a composite unique key on table

ALTER TABLE [TableName] ADD UNIQUE ([Column1], [Column2], [column3]);

You can put the file "hibernate.cfg.xml" to the src folder (src\hibernate.cfg.xml) and then init the config as the code below:

Configuration configuration = new Configuration();          
sessionFactory =configuration.configure().buildSessionFactory();

In similar situations, I've done well by putting something like the following into /etc/rc.local:

cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local  # check that rc.local ran

This has worked on multiple versions of Fedora and on Ubuntu 14.04 LTS, for both python and perl scripts.

If you are writing to a file, using a BufferedWriter instance, use the newLine() method of that instance. It provides a platform-independent way to write the new line in a file.

You could also try the dateparser module, which may be slower than datefinder on free text but which should cover more potential cases and date formats, as well as a significant number of languages.

For those stuck on windows (version >= server 2012 or win 8)and python 2.7,

import ctypes

class FILETIME(ctypes.Structure):
    _fields_ = [("dwLowDateTime", ctypes.c_uint),
                ("dwHighDateTime", ctypes.c_uint)]

    file_time = FILETIME()
    ctypes.windll.kernel32.GetSystemTimePreciseAsFileTime(ctypes.byref(file_time))
    return (file_time.dwLowDateTime + (file_time.dwHighDateTime << 32)) / 1.0e7

GetSystemTimePreciseAsFileTime function

Even if both work, I would use the latter. location is an object, and assigning a string to an object doesn't bode well for readability or maintenance.

Although I quite like the accepted answer, I think that, for completeness, this option should be mentioned as well:

if (item.Rate.GetValueOrDefault() == 0) { }

This solution

• does not require an additional method,
• is faster than all the other options, since GetValueOrDefault is a single field read operation¹ and
• reads easier than ((item.Rate ?? 0) == 0) (this might be a matter of taste, though).

¹ This should not influence your decision, though, since these kinds of micro-optimization are unlikely to make any difference.

int row_count = dt.Rows.Count;

The Integer class implements Comparable<Integer>, so you could try,

x.compareTo(y) == 0

also, if rather than equality, you are looking to compare these integers, then,

x.compareTo(y) < 0 will tell you if x is less than y.

x.compareTo(y) > 0 will tell you if x is greater than y.

Of course, it would be wise, in these examples, to ensure that x is non-null before making these calls.

If you need to use the latest versions of SciPy rather than the packaged version, without going through the hassle of building BLAS and LAPACK, you can follow the below procedure.

Install linear algebra libraries from repository (for Ubuntu),

sudo apt-get install gfortran libopenblas-dev liblapack-dev

Then install SciPy, (after downloading the SciPy source): python setup.py install or

pip install scipy

As the case may be.

I recently ran into this kinda issue, where I need to communicate between client and server using websocket in a PHP based codeigniter project.

I resolved this issue by adding my port(node app running on) into Allow incoming TCP ports & Allow outgoing TCP ports lists.

You can find these configurations in Firewall Configurations in your server's WHM panel.

ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.

But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:

sudo apt-get install libstdc++.i686

Maybe an easier way would be to add the pandas.Series into the pandas.DataFrame with ignore_index=True argument to DataFrame.append(). Example -

DF = DataFrame()
for sample,data in D_sample_data.items():
    SR_row = pd.Series(data.D_key_value)
    DF = DF.append(SR_row,ignore_index=True)

Demo -

In [1]: import pandas as pd

In [2]: df = pd.DataFrame([[1,2],[3,4]],columns=['A','B'])

In [3]: df
Out[3]:
   A  B
0  1  2
1  3  4

In [5]: s = pd.Series([5,6],index=['A','B'])

In [6]: s
Out[6]:
A    5
B    6
dtype: int64

In [36]: df.append(s,ignore_index=True)
Out[36]:
   A  B
0  1  2
1  3  4
2  5  6

Another issue in your code is that DataFrame.append() is not in-place, it returns the appended dataframe, you would need to assign it back to your original dataframe for it to work. Example -

DF = DF.append(SR_row,ignore_index=True)

To preserve the labels, you can use your solution to include name for the series along with assigning the appended DataFrame back to DF. Example -

DF = DataFrame()
for sample,data in D_sample_data.items():
    SR_row = pd.Series(data.D_key_value,name=sample)
    DF = DF.append(SR_row)
DF.head()

Authentication is done via a simple ldap_bind command that takes the users DN and the password. The user is authenticated when the bind is successfull. Usually you would get the users DN via an ldap_search based on the users uid or email-address.

Getting the users roles is something different as it is an ldap_search and depends on where and how the roles are stored in the ldap. But you might be able to retrieve the roles during the lap_search used to find the users DN.

C++ supplies a string class that can be used like this:

#include <string>
#include <iostream>

int main() {
    std::string Something = "Some text";
    std::cout << Something << std::endl;
}

look at String.indexOf and String.substring.

Make sure you check for -1 for indexOf.

Swift 3:

let alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.default, handler: nil))

     textField.placeholder = "Enter text:"
})

self.present(alert, animated: true, completion: nil)

One considerable difference is about porting Python2 to Python3. urllib2 does not exist for python3 and its methods ported to urllib. So you are using that heavily and want to migrate to Python3 in future, consider using urllib. However 2to3 tool will automatically do most of the work for you.

I was looking around for an answer on bulk inserting Objects.

The answer by Ragnar123 led me to making this function:

function bulkInsert(connection, table, objectArray, callback) {
  let keys = Object.keys(objectArray[0]);
  let values = objectArray.map( obj => keys.map( key => obj[key]));
  let sql = 'INSERT INTO ' + table + ' (' + keys.join(',') + ') VALUES ?';
  connection.query(sql, [values], function (error, results, fields) {
    if (error) callback(error);
    callback(null, results);
  });
}

bulkInsert(connection, 'my_table_of_objects', objectArray, (error, response) => {
  if (error) res.send(error);
  res.json(response);
});

Hope it helps!

This worked for me to bypass the proxy definitions:

1) become root

2) gem install -u gem_name gem_name

Hope you can work it out

Cached loop should be fastest (at least when called multiple times)

var factorial = (function() {
  var x =[];

  return function (num) {
    if (x[num] >0) return x[num];
    var rval=1;
    for (var i = 2; i <= num; i++) {
        rval = rval * i;
        x[i] = rval;
    }
    return rval;
  }
})();

You would use data validation for this. Click in the cell you want to have a multiple drop down > DATA > Validation > Criteria (List from a Range) - here you select form a list of items you want in the drop down. And .. you are good. I have included an example to reference.

this might be a solution, i have done something similar but this one does not seem to work for example if the necessary function requires administrator privileges it should ask you to restart it as admin.

@echo off
mkdir C:\Users\cmdfolder

if echo=="Access is denied." (goto :1A) else (goto :A4)

:A1
cls 
color 0d
echo restart this program as administator

:A4
pause

Second possibility is,

UPDATE TableB 
SET TableB.value = (
    SELECT TableA.value 
    FROM TableA
    WHERE TableA.name = TableB.name
);

Set these lines to OnResume as well and make sure if focusableInTouch is set to true while you initialize your controls

<controlName>.requestFocus();

<controlName>.requestFocusFromTouch();

You will need to build that CREATE TABLE statement from the inputs and then execute it.

A simple example:

declare @cmd nvarchar(1000), @TableName nvarchar(100);

set @TableName = 'NewTable';

set @cmd = 'CREATE TABLE dbo.' + quotename(@TableName, '[') + '(newCol int not null);';

print @cmd;

--exec(@cmd);

This is similar to an 'ls' but it does not take into account the prefix folder convention and will list the objects in the bucket. It's left up to the reader to filter out prefixes which are part of the Key name.

In Python 2:

from boto.s3.connection import S3Connection

conn = S3Connection() # assumes boto.cfg setup
bucket = conn.get_bucket('bucket_name')
for obj in bucket.get_all_keys():
    print(obj.key)

In Python 3:

from boto3 import client

conn = client('s3')  # again assumes boto.cfg setup, assume AWS S3
for key in conn.list_objects(Bucket='bucket_name')['Contents']:
    print(key['Key'])

Another option is to check for regular expression match on the command output.

For example:

[[ "$(./somecommand)" =~ "sub string" ]] && echo "Output includes 'sub string'"

By default

1. Primitives are passed by value. Unlikely to Java, string is primitive in PHP
2. Arrays of primitives are passed by value
3. Objects are passed by reference

4. Arrays of objects are passed by value (the array) but each object is passed by reference.

   <?php
   $obj=new stdClass();
   $obj->field='world';
   
   $original=array($obj);
   
   
   function example($hello) {
       $hello[0]->field='mundo'; // change will be applied in $original
       $hello[1]=new stdClass(); // change will not be applied in $original
       $
   }
   
   example($original);
   
   var_dump($original);
   // array(1) { [0]=> object(stdClass)#1 (1) { ["field"]=> string(5) "mundo" } } 
   

Note: As an optimization, every single value is passed as reference until its modified inside the function. If it's modified and the value was passed by reference then, it's copied and the copy is modified.

For me, this was the best solution:

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyData == Keys.Enter)
    {
        MessageBox.Show("Enter key pressed");
    }
}

If a node is so unhealthy that the master can't get status from it -- Kubernetes may not be able to restart the node. And if health checks aren't working, what hope do you have of accessing the node by SSH?

In this case, you may have to hard-reboot -- or, if your hardware is in the cloud, let your provider do it.

For example, the AWS EC2 Dashboard allows you to right-click an instance to pull up an "Instance State" menu -- from which you can reboot/terminate an unresponsive node.

Before doing this, you might choose to kubectl cordon node for good measure. And you may find kubectl delete node to be an important part of the process for getting things back to normal -- if the node doesn't automatically rejoin the cluster after a reboot.

Why would a node become unresponsive? Probably some resource has been exhausted in a way that prevents the host operating system from handling new requests in a timely manner. This could be disk, or network -- but the more insidious case is out-of-memory (OOM), which Linux handles poorly.

To help Kubernetes manage node memory safely, it's a good idea to do both of the following:

• Reserve some memory for the system.
• Be very careful with (avoid) opportunistic memory specifications for your pods. In other words, don't allow different values of requests and limits for memory.

The idea here is to avoid the complications associated with memory overcommit, because memory is incompressible, and both Linux and Kubernetes' OOM killers may not trigger before the node has already become unhealthy and unreachable.

What I've done is a bit manual, but I:

1. Merged the branches normally; Reverted the merge with revert;
2. Checked out all my files to HEAD~1, that is, their state in the merge commit;
3. Rebased my commits to hide this hackery from the commit history.

Ugly? Yes. Easy to remember? Also yes.

Encodings

In most cases, SQL Server stores Unicode data (i.e. that which is found in the XML and N-prefixed types) in UCS-2 / UTF-16 (storage is the same, UTF-16 merely handles Supplementary Characters correctly). This is not configurable: there is no option to use either UTF-8 or UTF-32 ^{(see UPDATE section at the bottom re: UTF-8 starting in SQL Server 2019)}. Whether or not the built-in functions can properly handle Supplementary Characters, and whether or not those are sorted and compared properly, depends on the Collation being used. The older Collations — names starting with SQL_ (e.g. SQL_Latin1_General_CP1_CI_AS) xor no version number in the name (e.g. Latin1_General_CI_AS) — equate all Supplementary Characters with each other (due to having no sort weight). Starting in SQL Server 2005 they introduced the 90 series Collations (those with _90_ in the name) that could at least do a binary comparison on Supplementary Characters so that you could differentiate between them, even if they didn't sort in the desired order. That also holds true for the 100 series Collations introduced in SQL Server 2008. SQL Server 2012 introduced Collations with names ending in _SC that not only sort Supplementary Characters properly, but also allow the built-in functions to interpret them as expected (i.e. treating the surrogate pair as a single entity). Starting in SQL Server 2017, all new Collations (the 140 series) implicitly support Supplementary Characters, hence there are no new Collations with names ending in _SC.

Starting in SQL Server 2019, UTF-8 became a supported encoding for CHAR and VARCHAR data (columns, variables, and literals), but not TEXT ^{(see UPDATE section at the bottom re: UTF-8 starting in SQL Server 2019)}.

Non-Unicode data (i.e. that which is found in the CHAR, VARCHAR, and TEXT types — but don't use TEXT, use VARCHAR(MAX) instead) uses an 8-bit encoding (Extended ASCII, DBCS, or EBCDIC). The specific character set / encoding is based on the Code Page, which in turn is based on the Collation of a column, or the Collation of the current database for literals and variables, or the Collation of the Instance for variable / cursor names and GOTO labels, or what is specified in a COLLATE clause if one is being used.

To see how locales match up to collations, check out:

• Windows Collation Name
• SQL Server Collation Name

To see the Code Page associated with a particular Collation (this is the character set and only affects CHAR / VARCHAR / TEXT data), run the following:

SELECT COLLATIONPROPERTY( 'Latin1_General_100_CI_AS' , 'CodePage' ) AS [CodePage];

To see the LCID (i.e. locale) associated with a particular Collation (this affects the sorting & comparison rules), run the following:

SELECT COLLATIONPROPERTY( 'Latin1_General_100_CI_AS' , 'LCID' ) AS [LCID];

To view the list of available Collations, along with their associated LCIDs and Code Pages, run:

SELECT [name],
       COLLATIONPROPERTY( [name], 'LCID' ) AS [LCID],
       COLLATIONPROPERTY( [name], 'CodePage' ) AS [CodePage]
FROM sys.fn_helpcollations()
ORDER BY [name];

Defaults

Before looking at the Server and Database default Collations, one should understand the relative importance of those defaults.

The Server (Instance, really) default Collation is used as the default for newly created Databases (including the system Databases: master, model, msdb, and tempdb). But this does not mean that any Database (other than the 4 system DBs) is using that Collation. The Database default Collation can be changed at any time (though there are dependencies that might prevent a Database from having it's Collation changed). The Server default Collation, however, is not so easy to change. For details on changing all collations, please see: Changing the Collation of the Instance, the Databases, and All Columns in All User Databases: What Could Possibly Go Wrong?

The server/Instance Collation controls:

• local variable names
• CURSOR names
• GOTO labels
• Instance-level meta-data

The Database default Collation is used in three ways:

• as the default for newly created string columns. But this does not mean that any string column is using that Collation. The Collation of a column can be changed at any time. Here knowing the Database default is important as an indication of what the string columns are most likely set to.
• as the Collation for operations involving string literals, variables, and built-in functions that do not take string inputs but produces a string output (i.e. IF (@InputParam = 'something') ). Here knowing the Database default is definitely important as it governs how these operations will behave.
• Database-level meta-data

The column Collation is either specified in the COLLATE clause at the time of the CREATE TABLE or an ALTER TABLE {table_name} ALTER COLUMN, or if not specified, taken from the Database default.

Since there are several layers here where a Collation can be specified (Database default / columns / literals & variables), the resulting Collation is determined by Collation Precedence.

All of that being said, the following query shows the default / current settings for the OS, SQL Server Instance, and specified Database:

SELECT os_language_version,
       ---
       SERVERPROPERTY('LCID') AS 'Instance-LCID',
       SERVERPROPERTY('Collation') AS 'Instance-Collation',
       SERVERPROPERTY('ComparisonStyle') AS 'Instance-ComparisonStyle',
       SERVERPROPERTY('SqlSortOrder') AS 'Instance-SqlSortOrder',
       SERVERPROPERTY('SqlSortOrderName') AS 'Instance-SqlSortOrderName',
       SERVERPROPERTY('SqlCharSet') AS 'Instance-SqlCharSet',
       SERVERPROPERTY('SqlCharSetName') AS 'Instance-SqlCharSetName',
       ---
       DATABASEPROPERTYEX(N'{database_name}', 'LCID') AS 'Database-LCID',
       DATABASEPROPERTYEX(N'{database_name}', 'Collation') AS 'Database-Collation',
  DATABASEPROPERTYEX(N'{database_name}', 'ComparisonStyle') AS 'Database-ComparisonStyle',
       DATABASEPROPERTYEX(N'{database_name}', 'SQLSortOrder') AS 'Database-SQLSortOrder'
FROM   sys.dm_os_windows_info;

Installation Default

Another interpretation of "default" could mean what default Collation is selected for the Instance-level collation when installing. That varies based on the OS language, but the (horrible, horrible) default for systems using "US English" is SQL_Latin1_General_CP1_CI_AS. In that case, the "default" encoding is Windows Code Page 1252 for VARCHAR data, and as always, UTF-16 for NVARCHAR data. You can find the list of OS language to default SQL Server collation here: Collation and Unicode support: Server-level collations. Keep in mind that these defaults can be overridden; this list is merely what the Instance will use if not overridden during install.

UPDATE 2018-10-02

SQL Server 2019 introduces native support for UTF-8 in VARCHAR / CHAR datatypes (not TEXT!). This is accomplished via a set of new collations, the names of which all end with _UTF8. This is an interesting capability that will definitely help some folks, but there are some "quirks" with it, especially when UTF-8 isn't being used for all columns and the Database's default Collation, so don't use it just because you have heard that UTF-8 is magically better. UTF-8 was designed solely for ASCII compatibility: to enable ASCII-only systems (i.e. UNIX back in the day) to support Unicode without changing any existing code or files. That it saves space for data using mostly (or only) US English characters (and some punctuation) is a side-effect. When not using mostly (or only) US English characters, data can be the same size as UTF-16, or even larger, depending on which characters are being used. And, in cases where space is being saved, performance might improve, but it might also get worse.

For a detailed analysis of this new feature, please see my post, "Native UTF-8 Support in SQL Server 2019: Savior or False Prophet?".

i think this is cool, even tho in general its good form to leave the caller of a method responsible for ensuring its called on the right thread.

if (![[NSThread currentThread] isMainThread]) {
    [self performSelector:_cmd onThread:[NSThread mainThread] withObject:someObject waitUntilDone:NO];
    return;
}

I'm not a git expert, but I think this should work:

git clone http://git.abc.net/git/abc.git
cd abc
git checkout my_abc 

OR

git clone http://git.abc.net/git/abc.git
cd abc
git checkout -b new_branch my_abc

The second variation establishes a new branch based on the tag, which lets you avoid a 'detached HEAD'. (git-checkout manual)

Every git repo contains the entire revision history, so cloning the repo gives you access to the latest commit, plus everything that came before, including the tag you're looking for.

As a button value is an attribute you need to use the .attr() method in jquery. This should do it

<script type="text/javascript">
    $(document).ready(function() {
        $('.my_button').click(function() {
            alert($(this).attr("value"));
        });
    });
</script>

You can also use attr to set attributes, more info in the docs.

This only works in JQuery 1.6+. See postpostmodern's answer for older versions.

Adding a roundabout answer here. I was struggling to install git on an RHEL 6.0 Amazon instance, and what ended up saving me was ... conda, as in Anaconda Python.

I installed conda on the command line from the archives (code modeled after this):

wget http://repo.continuum.io/miniconda/Miniconda2-4.2.12-Linux-x86_64.sh -O ~/miniconda.sh
bash ~/miniconda.sh -b -p $HOME/miniconda
export PATH="$HOME/miniconda/bin:$PATH"

and then ran

conda install git

and a relatively recent version git was installed. Today is 12/26/2016 and the version is 2.9.3.

Note: if you were on Branch1, you will with Git 2.0 (Q2 2014) be able to type:

git checkout Branch2
git rebase -

See commit 4f40740 by Brian Gesiak modocache:

rebase: allow "-" short-hand for the previous branch

Teach rebase the same shorthand as checkout and merge to name the branch to rebase the current branch on; that is, that "-" means "the branch we were previously on".

Sorry for resurrecting an ancient thread, but I recently wanted to do this, but I wanted a 100% portable bash script to do it. So here's my solution using only grep and sed.

The below was bashed out very quickly, and so could be made much more elegant, but I'm just getting started really with sed/awk etc...

curl "http://www.webpagewithtableinit.com/" 2>/dev/null | grep -i -e '</\?TABLE\|</\?TD\|</\?TR\|</\?TH' | sed 's/^[\ \t]*//g' | tr -d '\n' | sed 's/<\/TR[^>]*>/\n/Ig'  | sed 's/<\/\?\(TABLE\|TR\)[^>]*>//Ig' | sed 's/^<T[DH][^>]*>\|<\/\?T[DH][^>]*>$//Ig' | sed 's/<\/T[DH][^>]*><T[DH][^>]*>/,/Ig'

As you can see I've got the page source using curl, but you could just as easily feed in the table source from elsewhere.

Here's the explanation:

Get the Contents of the URL using cURL, dump stderr to null (no progress meter)

curl "http://www.webpagewithtableinit.com/" 2>/dev/null 

.

I only want Table elements (return only lines with TABLE,TR,TH,TD tags)

| grep -i -e '</\?TABLE\|</\?TD\|</\?TR\|</\?TH'

.

Remove any Whitespace at the beginning of the line.

| sed 's/^[\ \t]*//g' 

.

Remove newlines

| tr -d '\n\r' 

.

Replace </TR> with newline

| sed 's/<\/TR[^>]*>/\n/Ig'  

.

Remove TABLE and TR tags

| sed 's/<\/\?\(TABLE\|TR\)[^>]*>//Ig' 

.

Remove ^<TD>, ^<TH>, </TD>$, </TH>$

| sed 's/^<T[DH][^>]*>\|<\/\?T[DH][^>]*>$//Ig' 

.

Replace </TD><TD> with comma

| sed 's/<\/T[DH][^>]*><T[DH][^>]*>/,/Ig'

.

Note that if any of the table cells contain commas, you may need to escape them first, or use a different delimiter.

Hope this helps someone!

I know this is an older thread but I wanted to give what I think to be helpful information.

I personally use PyPy which is really easy to install using pip. I interchangeably use Python/PyPy interpreter, you don't need to change your code at all and I've found it to be roughly 40x faster than the standard python interpreter (Either Python 2x or 3x). I use pyCharm Community Edition to manage my code and I love it.

I like writing code in python as I think it lets you focus more on the task than the language, which is a huge plus for me. And if you need it to be even faster, you can always compile to a binary for Windows, Linux, or Mac (not straight forward but possible with other tools). From my experience, I get about 3.5x speedup over PyPy when compiling, meaning 140x faster than python. PyPy is available for Python 3x and 2x code and again if you use an IDE like PyCharm you can interchange between say PyPy, Cython, and Python very easily (takes a little of initial learning and setup though).

Some people may argue with me on this one, but I find PyPy to be faster than Cython. But they're both great choices though.

Edit: I'd like to make another quick note about compiling: when you compile, the resulting binary is much bigger than your python script as it builds all dependencies into it, etc. But then you get a few distinct benefits: speed!, now the app will work on any machine (depending on which OS you compiled for, if not all. lol) without Python or libraries, it also obfuscates your code and is technically 'production' ready (to a degree). Some compilers also generate C code, which I haven't really looked at or seen if it's useful or just gibberish. Good luck.

Hope that helps.

/([0-9]+[.,]*)+/ matches any number with or without coma or dots

it can match

         122
         122,354
         122.88
         112,262,123.7678

bug: it also matches 262.4377,3883 ( but it doesn't matter parctically)

It can take time for the network close to be observed - the total time is nominally about 2 minutes (yes, minutes!) after a close before the packets destined for the port are all assumed to be dead. The error condition is detected at some point. With a small write, you are inside the MTU of the system, so the message is queued for sending. With a big write, you are bigger than the MTU and the system spots the problem quicker. If you ignore the SIGPIPE signal, then the functions will return EPIPE error on a broken pipe - at some point when the broken-ness of the connection is detected.

A very straight forward approach is to use an installed Adobe Reader or any other PDF viewer capable of printing:

Process p = new Process( );
p.StartInfo = new ProcessStartInfo( )
{
    CreateNoWindow = true,
    Verb = "print",
    FileName = path //put the correct path here
};
p.Start( );

Another way is to use a third party component, e.g. PDFView4NET

I believe your question is to change only width of view dynamically, whereas above methods will change layout properties completely to new one, so I suggest to getLayoutParams() from view first, then set width on layoutParams, and finally set layoutParams to the view, so following below steps to do the same.

View view = findViewById(R.id.nutrition_bar_filled);
LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = newWidth;
view.setLayoutParams(layoutParams);

import subprocess
ping_response = subprocess.Popen(["/bin/ping", "-c1", "-w100", "192.168.0.1"], stdout=subprocess.PIPE).stdout.read()

Just in case you want to handle the behaviour of the back button (at the bottom of the phone) and the home button (the one to the left of the action bar), this custom activity I'm using in my project may help you.

import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;

/**
 * Activity where the home action bar button behaves like back by default
 */
public class BackActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setupHomeButton();
    }

    private void setupHomeButton() {
        final ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeButtonEnabled(true);
        }
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onMenuHomePressed();
                return true;
        }
        return super.onOptionsItemSelected(item);
    }

    protected void onMenuHomePressed() {
        onBackPressed();
    }
}

Example of use in your activity:

public class SomeActivity extends BackActivity {

    // ....

    @Override
    public void onBackPressed()
    {
        // Example of logic
        if ( yourConditionToOverride ) {
            // ... do your logic ...
        } else {
            super.onBackPressed();
        }
    }    
}

In VB its normally Dir to find the directory of the file. If it's not blank then it exists and then use Kill to get rid of the file.

test = Dir(Filename)
If Not test = "" Then
    Kill (Filename)
End If

for more exactly positioning:

      background-position: bottom 5px right 7px;

If you switch to the jQuery UI Dialog box, you can initialize the buttons array with the appropriate names like:

$("#id").dialog({
  buttons: {
    "Yes": function() {},
    "No": function() {}
  }
});

For the second part of your question, you can also use shift, for example:

df['t-1'] = df['t'].shift(1)

t-1 would then contain the values from t one row above.

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.shift.html

On Chrome 16, and possibly earlier versions, you can use "\n". As a sidenote, "\t" also works

This is strictly not speaking using jQuery, but I have found this method easier than using jQuery. There are probably endless methods of achieving this and many clever ones here, but not all have worked for me. However the following method has always worked and I am passing it one in case it helps someone else.

Three javascript libraries are required, createCookie, readCookie and eraseCookie. These libraries are not mine but I began using them about 5 years ago and don't know their origin.

createCookie = function(name, value, days) {
if (days) {
    var date = new Date();
    date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
    var expires = "; expires=" + date.toGMTString();
}
else var expires = "";

document.cookie = name + "=" + value + expires + "; path=/";
}

readCookie = function (name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
    var c = ca[i];
    while (c.charAt(0) == ' ') c = c.substring(1, c.length);
    if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
eraseCookie = function (name) {
   createCookie(name, "", -1);
}

To call them you need to create a small PHP function, normally as part of your support library, as follows:

<?php
 function createjavaScriptCookie($sessionVarible) {
 $s =  "<script>";
 $s = $s.'createCookie('. '"'. $sessionVarible                 
 .'",'.'"'.$_SESSION[$sessionVarible].'"'. ',"1"'.')';
 $s = $s."</script>";
 echo $s;
}
?>

So to use all you now have to include within your index.php file is

$_SESSION["video_dir"] = "/video_dir/";
createjavaScriptCookie("video_dir");

Now in your javascript library.js you can recover the cookie with the following code:

var videoPath = readCookie("video_dir") +'/'+ video_ID + '.mp4';

I hope this helps.

You can use this selector to undermouse object and then manipulate it as a jQuery object:

$(':hover').last();

If you are planning to get the image from its path, it's better to use Assets instead of trying to figure out the path of the drawable folder.

    InputStream stream = getAssets().open("image.png");
    Drawable d = Drawable.createFromStream(stream, null);

IIS uses Integrated Authentication and by default IE has the ability to use your windows user account...but don't worry, so does Firefox but you'll have to make a quick configuration change.

1) Open up Firefox and type in about:config as the url

2) In the Filter Type in ntlm

3) Double click "network.automatic-ntlm-auth.trusted-uris" and type in localhost and hit enter

4) Write Thank You To Blogger

As Always, Hope this helped you out.

In order to install compass On Mac OS X 10.10 (Yosemite)had to perform the following:

1. Set Up Ruby Environment

• Ensure ruby is installed and up to date: ruby -v
• Update gem's sudo gem update --system

2. Set Up MAC Environment

Install the Xcode Command Line Tools this is the key to install Compass.

xcode-select --install

Installing the Xcode Command Line Tools are the key to getting Compass working on OS X

3. Install Compass

sudo gem install compass

Use extension methods. Replace NameOfContext with the name of your object context.

public static class Extensions{
   public static IQueryable<Company> CompleteCompanies(this NameOfContext context){
         return context.Companies
             .Include("Employee.Employee_Car")
             .Include("Employee.Employee_Country") ;
     }

     public static Company CompanyById(this NameOfContext context, int companyID){
         return context.Companies
             .Include("Employee.Employee_Car")
             .Include("Employee.Employee_Country")
             .FirstOrDefault(c => c.Id == companyID) ;
      }

}

Then your code becomes

     Company company = 
          context.CompleteCompanies().FirstOrDefault(c => c.Id == companyID);

     //or if you want even more
     Company company = 
          context.CompanyById(companyID);

Besides put all your assets in the public folder, you can use the HTML::image() Method, and only needs an argument which is the path to the image, relative on the public folder, as well:

{{ HTML::image('imgs/picture.jpg') }}

Which generates the follow HTML code:

<img src="http://localhost:8000/imgs/picture.jpg">

The link to other elements of HTML::image() Method: http://laravel-recipes.com/recipes/185/generating-an-html-image-element

You can have both formats as an argument to the function date():

date("d-m-Y H:i:s")

Check the manual for more info : http://php.net/manual/en/function.date.php

As pointed out by @ThomasVdBerge to display minutes you need the 'i' character

This is what I am doing for my need, Where I need to send the login data to API as form data and the Javascript Object(userData) is getting converted automatically to URL encoded data

        var deferred = $q.defer();
        $http({
            method: 'POST',
            url: apiserver + '/authenticate',
            headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
            transformRequest: function (obj) {
                var str = [];
                for (var p in obj)
                    str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
                return str.join("&");
            },
            data: userData
        }).success(function (response) {
            //logics
            deferred.resolve(response);
        }).error(function (err, status) {
           deferred.reject(err);
        });

This how my Userdata is

var userData = {
                grant_type: 'password',
                username: loginData.userName,
                password: loginData.password
            }

$foo = 42;
$bar = function($x = 0) use ($foo){
    return $x + $foo;
};
var_dump($bar(10)); // int(52)

UPDATE: there is now support for arrow functions, but i will let for someone that used it more to create the answer

When you want to destroy a session completely, you need to do more then just

session_destroy();

First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:

<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>

The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.

Edit:

You need to remove the () from your exit code near the top of your script. it should just be

exit;

Rewrite of Igor's code as plugin.

Use:

$('input[type=radio]').uncheckableRadio();

Plugin:

(function( $ ){

    $.fn.uncheckableRadio = function() {

        return this.each(function() {
            $(this).mousedown(function() {
                $(this).data('wasChecked', this.checked);
            });

            $(this).click(function() {
                if ($(this).data('wasChecked'))
                    this.checked = false;
            });
        });

    };

})( jQuery );

It means the file containing main doesn't have access to the player structure definition (i.e. doesn't know what it looks like).

Try including it in header.h or make a constructor-like function that allocates it if it's to be an opaque object.

EDIT

If your goal is to hide the implementation of the structure, do this in a C file that has access to the struct:

struct player *
init_player(...)
{
    struct player *p = calloc(1, sizeof *p);

    /* ... */
    return p;
}

However if the implementation shouldn't be hidden - i.e. main should legally say p->canPlay = 1 it would be better to put the definition of the structure in header.h.

What I believe user2087510 meant was:

name = 'something'
name = name.replace("'", "\\'")

I have also used this with success.

Alternatively you could just use a document.write:

<script type="text\javascript">
var loc = "http://";
document.write('<a href="' + loc + '">Link text</a>');
</script>

Actually, when you do not want to use external sources (or cannot), I would recommend:

DEVICE=$(ls -l /sys/class/net | awk '$NF~/pci0/ { print $(NF-2); exit }')
IPADDR=$(ip -br address show dev $DEVICE | awk '{print substr($3,1,index($3,"/")-1);}')

The first line gets the name of the first network device on the PCI bus, the second one gives you its IP address.

BTW ps ... | grep ... | awk ... stinks. awk does not need grep.

Using str_replace() to remove the dots is not overkill.

$string_number = '1.512.523,55';
// NOTE: You don't really have to use floatval() here, it's just to prove that it's a legitimate float value.
$number = floatval(str_replace(',', '.', str_replace('.', '', $string_number)));

// At this point, $number is a "natural" float.
print $number;

This is almost certainly the least CPU-intensive way you can do this, and odds are that even if you use some fancy function to do it, that this is what it does under the hood.

For me, this error came up when I was trying to rollback a transaction block after encountering an exception, inside another transaction block.

All I had to do to fix it was to remove my inner transaction block.

Things can get quite messy when using nested transactions, best to avoid this and just restructure your code.

From the documentation:

1. get cookie from response

   url = 'http://example.com/some/cookie/setting/url'
   r = requests.get(url)
   r.cookies
   

   {'example_cookie_name': 'example_cookie_value'}

2. give cookie back to server on subsequent request

   url = 'http://httpbin.org/cookies'
   cookies = dict(cookies_are='working')
   r = requests.get(url, cookies=cookies)`
   

Based on what I read from different sources:

An await expression does not block the thread on which it is executing. Instead, it causes the compiler to sign up the rest of the async method as a continuation on the awaited task. Control then returns to the caller of the async method. When the task completes, it invokes its continuation, and execution of the async method resumes where it left off.

To wait for a single task to complete, you can call its Task.Wait method. A call to the Wait method blocks the calling thread until the single class instance has completed execution. The parameterless Wait() method is used to wait unconditionally until a task completes. The task simulates work by calling the Thread.Sleep method to sleep for two seconds.

This article is also a good read.

df.apply(axis=0, func=lambda x : any(pd.isnull(x)))

Will check for each column if it contains Nan or not.

Exceute the program by pressing SHIFT+F6, instead of clicking the RUN button on the window. This might be silly, bt the error main class not found is not occurring, the project is executing well...

There's nothing innately wrong with the string form.

Rather than avoid the "global" strict form for worry of concatenating non-strict javascript, it's probably better to just fix the damn non-strict javascript to be strict.

having two tables for head and body worked for me

var ref = Request.ServerVariables("HTTP_REFERER");

Type within the quotes any other server variable name you want.

You need to import PIL (Pillow) for this. Suppose you have an image of size 1200, 1600. We will crop image from 400, 400 to 800, 800

from PIL import Image
img = Image.open("ImageName.jpg")
area = (400, 400, 800, 800)
cropped_img = img.crop(area)
cropped_img.show()

You can use "DATE" as a data type while you are creating the table. In this way, you can avoid the above error. Eg:

CREATE TABLE Employee (birth_date DATE);
INSERT INTO Employee VALUES('1967-11-17');

Apparently, the system I was using had the docker-ce not Docker. Thus, running below command did the trick.

sudo apt-get purge docker-ce

sudo rm -rf /var/lib/docker

hope it helps

@echo off 
    setlocal enableextensions disabledelayedexpansion

    set "search=%1"
    set "replace=%2"

    set "textFile=Input.txt"

    for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
        set "line=%%i"
        setlocal enabledelayedexpansion
        >>"%textFile%" echo(!line:%search%=%replace%!
        endlocal
    )

for /f will read all the data (generated by the type comamnd) before starting to process it. In the subprocess started to execute the type, we include a redirection overwritting the file (so it is emptied). Once the do clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.

    super.onCreate(savedInstanceState);

If you need a directive more advanced, I recomend the solution that I implemnted, correctly tested on Internet Explorer 11, Chrome and FireFox.

I hope it, will be helpfull.

HTML :

<a href="#" class="btn btn-default" file-name="'fileName.extension'"  ng-click="getFile()" file-download="myBlobObject"><i class="fa fa-file-excel-o"></i></a>

        OutputStream outStream=null;
outStream = response.getOutputStream();//is important manage the exceptions here
ObjectThatWritesOnOutputStream myWriter= new ObjectThatWritesOnOutputStream();// note that this object doesn exist on JAVA,
ObjectThatWritesOnOutputStream.write(outStream);//you can configure more things here
outStream.flush();
return;
}

best and simple way is to put title inside a span and replace then.

'<div id="'+div_id+'" class="widget" style="height:60px;width:110px">\n\
        <div class="widget-head ui-widget-header" 
                style="cursor:move;height:20px;width:130px">'+
     '<span id="'+span_id+'" style="float:right; cursor:pointer" 
            class="dialog_link ui-icon ui-icon-newwin ui-icon-pencil"></span>' +
      '<span id="spTitle">'+
      dialog_title+ '</span>'
 '</div></div>

now you can simply use this:

$('#'+div_id+' .widget-head sp#spTitle').text("new dialog title");

Also with dict

a = []
b = {1:'one'}

a.append(dict(b))
print a
b[1]='iuqsdgf'
print a

result

[{1: 'one'}]
[{1: 'one'}]

Here's an example that reads a list of CSV strings into a list of lists and then loops through that list of lists and prints the CSV strings back out to the console.

import java.util.ArrayList;
import java.util.List;

public class ListExample
{
    public static void main(final String[] args)
    {
        //sample CSV strings...pretend they came from a file
        String[] csvStrings = new String[] {
                "abc,def,ghi,jkl,mno",
                "pqr,stu,vwx,yz",
                "123,345,678,90"
        };

        List<List<String>> csvList = new ArrayList<List<String>>();

        //pretend you're looping through lines in a file here
        for(String line : csvStrings)
        {
            String[] linePieces = line.split(",");
            List<String> csvPieces = new ArrayList<String>(linePieces.length);
            for(String piece : linePieces)
            {
                csvPieces.add(piece);
            }
            csvList.add(csvPieces);
        }

        //write the CSV back out to the console
        for(List<String> csv : csvList)
        {
            //dumb logic to place the commas correctly
            if(!csv.isEmpty())
            {
                System.out.print(csv.get(0));
                for(int i=1; i < csv.size(); i++)
                {
                    System.out.print("," + csv.get(i));
                }
            }
            System.out.print("\n");
        }
    }
}

Pretty straightforward I think. Just a couple points to notice:

1. I recommend using "List" instead of "ArrayList" on the left side when creating list objects. It's better to pass around the interface "List" because then if later you need to change to using something like Vector (e.g. you now need synchronized lists), you only need to change the line with the "new" statement. No matter what implementation of list you use, e.g. Vector or ArrayList, you still always just pass around List<String>.

2. In the ArrayList constructor, you can leave the list empty and it will default to a certain size and then grow dynamically as needed. But if you know how big your list might be, you can sometimes save some performance. For instance, if you knew there were always going to be 500 lines in your file, then you could do:

List<List<String>> csvList = new ArrayList<List<String>>(500);

That way you would never waste processing time waiting for your list to grow dynamically grow. This is why I pass "linePieces.length" to the constructor. Not usually a big deal, but helpful sometimes.

Hope that helps!

Robocopy, or "Robust File Copy", is a command-line directory replication command. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was introduced as a standard feature of Windows Vista, Windows 7 and Windows Server 2008.

   robocopy c:\Sourcepath c:\Destpath /E /XC /XN /XO

To elaborate (using Hydrargyrum, HailGallaxar and Andy Schmidt answers):

• /E makes Robocopy recursively copy subdirectories, including empty ones.
• /XC excludes existing files with the same timestamp, but different file sizes. Robocopy normally overwrites those.
• /XN excludes existing files newer than the copy in the destination directory. Robocopy normally overwrites those.
• /XO excludes existing files older than the copy in the destination directory. Robocopy normally overwrites those.

With the Changed, Older, and Newer classes excluded, Robocopy does exactly what the original poster wants - without needing to load a scripting environment.

Because boolean data type is stored like an integer, bit operator ^ functions like a XOR operation if used with boolean values.

//©Mfpl - XOR_Test.java

    public class XOR_Test {
        public static void main (String args[]) {
            boolean a,b;

            a=false; b=false;
            System.out.println("a=false; b=false;  ->  " + (a^b));

            a=false; b=true;
            System.out.println("a=false; b=true;  ->  " + (a^b));

            a=true;  b=false;
            System.out.println("a=true;  b=false;  ->  " + (a^b));

            a=true; b=true;
            System.out.println("a=true; b=true;  ->  " + (a^b));

            /*  output of this program:

                    a=true;  b=false;  ->  true
                    a=true; b=true;  ->  false
            */
        }
    }

In PHP>=5.3 and based on Luc M's answer (the first one) you can make use of closures like this

array_walk_recursive($aNonFlat, function(&$v, $k, &$t){$t->aFlat[] = $v;}, $objTmp);

I love this because I don't have to surround the function's code with quotes like when using create_function()

I faced this issue, while connecting DB, the variable to connect to db was not defined.

Cause: php tried to connect to the db with undefined variable for db host (localhost/127.0.0.1/... any other ip or domain) but failed to trace the domain.

Solution: Make sure the db host is properly defined.

From the Sublime Text docs for Windows/Linux:

Keypress            Command
Ctrl + K, Ctrl + U  Transform to Uppercase
Ctrl + K, Ctrl + L  Transform to Lowercase

and for Mac:

Keypress    Command
cmd + KU    Transform to Uppercase
cmd + KL    Transform to Lowercase

Also note that Ctrl + Shift + p in Windows (? + Shift + p in a Mac) brings up the Command Palette where you can search for these and other commands. It looks like this:

If you don't want to modify the databound object from some reason (for example you want to show some view in your grid, but you don't want it as a part of the datasource object), you might want to do this:

1.Add column manually:

    DataGridViewColumn c = new DataGridViewColumn();
    DataGridViewCell cell = new DataGridViewTextBoxCell();

    c.CellTemplate = cell;
    c.HeaderText = "added";
    c.Name = "added";
    c.Visible = true;
dgv.Columns.Insert(0, c); 

2.In the DataBindingComplete event do something like this:

foreach (DataGridViewRow row in dgv.Rows)
{if (row.Cells[7].Value.ToString()=="1")
row.Cells[0].Value = "number one"; }

(just a stupid example)

but remember IT HAS to be in the DataBindingComplete, otherwise value will remain blank

Yes, a menu gives you the bar but it doesn't give you any items to put in the bar. You need something like (from one of my own projects):

<!-- Menu. -->
<Menu Width="Auto" Height="20" Background="#FFA9D1F4" DockPanel.Dock="Top">
    <MenuItem Header="_Emulator">
    <MenuItem Header="Load..." Click="MenuItem_Click" />
    <MenuItem Header="Load again" Click="menuEmulLoadLast" />
    <Separator />
    <MenuItem Click="MenuItem_Click">
        <MenuItem.Header>
            <DockPanel>
                <TextBlock>Step</TextBlock>
                <TextBlock Width="10"></TextBlock>
                <TextBlock HorizontalAlignment="Right">F2</TextBlock>
            </DockPanel>
        </MenuItem.Header>
    </MenuItem>
    :

You need to subscribe to the KeyDown event on the text box. Then something like this:

private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
    if (!char.IsControl(e.KeyChar) 
       && !char.IsDigit(e.KeyChar) 
       && e.KeyChar != '.' && e.KeyChar != '+' && e.KeyChar != '-'
       && e.KeyChar != '(' && e.KeyChar != ')' && e.KeyChar != '*' 
       && e.KeyChar != '/')
    {
        e.Handled = true;
        return;
    }
    e.Handled=false;
    return;
}

The important thing to know is that if you changed the Handled property to true, it will not process the keystroke. Setting it to false will.

Taking for granted that the JSON you posted is actually what you are seeing in the browser, then the problem is the JSON itself.

The JSON snippet you have posted is malformed.

You have posted:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe"[{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }]

while the correct JSON would be:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe" : [{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }
        ]
    }
]

Put the following code in the <head> section:

<meta http-equiv="refresh" content="0; url=http://address/">

To see the index for a specific table use SHOW INDEX:

SHOW INDEX FROM yourtable;

To see indexes for all tables within a specific schema you can use the STATISTICS table from INFORMATION_SCHEMA:

SELECT DISTINCT
    TABLE_NAME,
    INDEX_NAME
FROM INFORMATION_SCHEMA.STATISTICS
WHERE TABLE_SCHEMA = 'your_schema';

Removing the where clause will show you all indexes in all schemas.

I tested with:

$("div.error").remove();
$(".error").removeClass("error");

It will be ok, when you need to validate it again.

If you want to measure code efficiency, or in any other way measure time intervals, the following will be easier:

#include <time.h>

int main()
{
   clock_t start = clock();
   //... do work here
   clock_t end = clock();
   double time_elapsed_in_seconds = (end - start)/(double)CLOCKS_PER_SEC;
   return 0;
}

Centered and middled content ?

Do it this way :

<table style="width:100%">
    <tr>
        <td valign="middle" align="center">Table once ruled centering</td>
    </tr>
</table>

I fiddled it here

Ha, let me guess .. you want DIVs ..

just make your first outter DIV behave like a table-cell then style it with vertical align:middle;

<div>
    <p>I want this paragraph to be at the center, but I can't.</p>
</div>

div {
    width:500px;
    height:100px;
    background-color:aqua;
    text-align:center;
    /*  there it is */
    display:table-cell;
    vertical-align:middle;
}

Also note that if, for whatever reason, you make a method in a @Service as final, the autowired beans you will access from it will always be null.

Although parseInt is the official function to do this, you can achieve the same with this code:

number*1

The advantage is that you save some characters, which might save bandwidth if your code has to lots of such conversations.

And for vim 7.4+ you can use (preferably on your .vimrc) (thanks to ??? for that last bit of news!):

:set nofixendofline

Now regarding older versions of vim.

Even if the file was already saved with new lines at the end:

vim -b file and once in vim:

:set noeol
:wq

done.

alternatively you can open files in vim with :e ++bin file

Yet another alternative:

:set binary
:set noeol
:wq

see more details at Why do I need vim in binary mode for 'noeol' to work?

Try adding a view users/show.json.erb This should be rendered when you make a request for the JSON format, and you get the added benefit of it being rendered by erb too, so your file could look something like this

{
    "first_name": "<%= @user.first_name.to_json %>",
    "last_name": "<%= @user.last_name.to_json %>"
}

The below code helps to get the details of elements from the specific form with the form id,

$('#formId input, #formId select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements from all the forms which are place in the loading page,

$('form input, form select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements which are place in the loading page even when the element is not place inside the tag,

$('input, select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

NOTE: We add the more element tag name what we need in the object list like as below,

Example: to get name of attribute "textarea",

$('input, select, textarea').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

This post is already a year old... but, I really, really like the ES6 @dzuc answer. However it is incomplete by not been able to handle multiple selects or checkboxes. This has already pointed and code solutions has been offered. I find them heavy and not optimized. So I wrote a 2 versions based on @dzuc to handle these cases:

• For ASP style forms where multiple items name could just simple repeated.

let r=Array.from(fd).reduce(
  (o , [k,v]) => (
     (!o[k])
     ? {...o , [k] : v}
     : {...o , [k] : [...o[k] , v]}
   )
   ,{}
);
let obj=JSON.stringify(r);

One line Hotshot version:

Array.from(fd).reduce((o,[k,v])=>((!o[k])?{...o,[k]:v}:{...o,[k]:[...o[k],v]}),{});

• For PHP style forms where the multiple item names must have a [] suffix.

let r=Array.from(fd).reduce(
  (o , [k,v]) => (
    (k.split('[').length>1)
    ? (k=k.split('[')[0]
      , (!o[k])
      ? {...o , [k] : [v]}
      : {...o , [k] : [...o[k] , v ]}
    )

  )
  ,{}

let obj=JSON.stringify(r);

One line Hotshot version:

Array.from(fd).reduce((o,[k,v])=>((k.split('[').length>1)?(k=k.split('[')[0],(!o[k])?{...o,[k]:[v]}:{...o,[k]:[...o[k],v]}):{...o,[k]:v}),{});

• Extension of PHP form that support multi-level arrays.

Since last time I wrote the previous second case, at work it came a case that the PHP form has checkboxes on multi-levels. I wrote a new case to support previous case and this one. I created a snippet to better showcase this case, the result show on the console for this demo, modify this to your need. Tried to optimize it the best I could without compromising performance, however, it compromise some human readability. It takes advantage that arrays are objects and variables pointing to arrays are kept as reference. No hotshot for this one, be my guest.

Another—as of yet unmentioned—reason for favoring pip is because it is the new hotness and will continue to be used in the future.

The infographic below—from the Current State of Packaging section in the The Hitchhiker's Guide to Packaging v1.0—shows that setuptools/easy_install will go away in the future.

Here's another infographic from distribute's documentation showing that Setuptools and easy_install will be replaced by the new hotness—distribute and pip. While pip is still the new hotness, Distribute merged with Setuptools in 2013 with the release of Setuptools v0.7.

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

Angular 8 & rxjs 6 in 2019 version

I would like to share the solution based on others great solutions.

First make a service to listen for routes changes and save the last previous route in a Behavior Subject, then provide this service in the main app.component in constructor then use this service to get the previous route you want when ever you want.

use case: you want to redirect the user to an advertise page then auto redirect him/her to where he did came from so you need the last previous route to do so.

// service : route-events.service.ts

import { Injectable } from '@angular/core';
import { Router, RoutesRecognized } from '@angular/router';
import { BehaviorSubject } from 'rxjs';
import { filter, pairwise } from 'rxjs/operators';
import { Location } from '@angular/common';

@Injectable()
export class RouteEventsService {

    // save the previous route
  public previousRoutePath = new BehaviorSubject<string>('');

  constructor(
    private router: Router,
    private location: Location
  ) {

    // ..initial prvious route will be the current path for now
    this.previousRoutePath.next(this.location.path());


    // on every route change take the two events of two routes changed(using pairwise)
    // and save the old one in a behavious subject to access it in another component
    // we can use if another component like intro-advertise need the previous route
    // because he need to redirect the user to where he did came from.
    this.router.events.pipe(
      filter(e => e instanceof RoutesRecognized),
      pairwise(),
        )
    .subscribe((event: any[]) => {
        this.previousRoutePath.next(event[0].urlAfterRedirects);
    });

  }
}

provide the service in app.module

  providers: [
    ....
    RouteEventsService,
    ....
  ]

Inject it in app.component

  constructor(
    private routeEventsService: RouteEventsService
  )

finally use the saved previous route in the component you want

  onSkipHandler(){
    // navigate the user to where he did came from
    this.router.navigate([this.routeEventsService.previousRoutePath.value]);
  }

Wouldn't something like this work?

$("body *").not(".form_wrapper").click(function() {

});

or

$("body *:not(.form_wrapper)").click(function() {

});

They are not doing the same job: $emit dispatches an event upwards through the scope hierarchy, while $broadcast dispatches an event downwards to all child scopes.

You need to change some setting in your php.ini:

upload_max_filesize = 2M 
;or whatever size you want

max_execution_time = 60
; also, higher if you must - sets the maximum time in seconds

Were your PHP.ini is located depends on your environment, more information: http://php.net/manual/en/ini.list.php

For anybody else stumbling over this, the same happened to me while trying to send a SOAP request header to a SOAP service. The issue was a wrong order in the code, I requested the input stream first before sending the XML body. In the code snipped below, the line InputStream in = conn.getInputStream(); came immediately after ByteArrayOutputStream out = new ByteArrayOutputStream(); which is the incorrect order of things.

ByteArrayOutputStream out = new ByteArrayOutputStream();
// send SOAP request as part of HTTP body 
byte[] data = request.getHttpBody().getBytes("UTF-8");
conn.getOutputStream().write(data); 

if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
  Log.d(TAG, "http response code is " + conn.getResponseCode());
  return null;
}

InputStream in = conn.getInputStream();

FileNotFound in this case was an unfortunate way to encode HTTP response code 400.

First you need query Intent to handler sharing option. Then use package name to filter Intent then we will have only one Intent that handler sharing option!

Share via Facebook

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Content to share");
PackageManager pm = v.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList) {
    if ((app.activityInfo.name).contains("facebook")) {
        final ActivityInfo activity = app.activityInfo;
        final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);
        shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |             Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
        shareIntent.setComponent(name);
        v.getContext().startActivity(shareIntent);
        break;
   }
}

Bonus - Share via Twitter

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Content to share");
PackageManager pm = v.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList) {
    if ("com.twitter.android.PostActivity".equals(app.activityInfo.name)) {
        final ActivityInfo activity = app.activityInfo;
        final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);
        shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |             Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
        shareIntent.setComponent(name);
        v.getContext().startActivity(shareIntent);
        break;
   }
}

The above methods seems to be complex. Use my method as a reference.

I have this two files

run.php

mkdir.py

Here, I've created a html page which contains GO button. Whenever you press this button a new folder will be created in directory whose path you have mentioned.

run.php

<html>
 <body>
  <head>
   <title>
     run
   </title>
  </head>

   <form method="post">

    <input type="submit" value="GO" name="GO">
   </form>
 </body>
</html>

<?php
    if(isset($_POST['GO']))
    {
        shell_exec("python /var/www/html/lab/mkdir.py");
        echo"success";
    }
?>

mkdir.py

#!/usr/bin/env python    
import os    
os.makedirs("thisfolder");

Ubuntu 18.04 LTS

These are the steps which worked for me. Many, many thanks to William Desportes for providing the automatic updates on their Ubuntu PPA.

Step 1 (from William Desportes post)
$ sudo add-apt-repository ppa:phpmyadmin/ppa

Step 2
$ sudo apt-get --with-new-pkgs upgrade

Step 3
$ sudo service mysql restart

If you have issues restarting mysql, you can also restart with the following sequence
$ sudo service mysql stop;
$ sudo service mysql start;

- (IBAction)toggleSpinner:(id)sender
{
    if (self.spinner.isAnimating)
    {
        [self.spinner stopAnimating];
        ((UIButton *)sender).titleLabel.text = @"Start spinning";
        [self.controlState setValue:[NSNumber numberWithBool:NO] forKey:@"SpinnerAnimatingState"];
    }
    else
    {
        [self.spinner startAnimating];
        ((UIButton *)sender).titleLabel.text = @"Stop spinning";
        [self.controlState setValue:[NSNumber numberWithBool:YES] forKey:@"SpinnerAnimatingState"];
    }
}

You should have to add only minViewMode: "months" in your datepicker function.

Here you go.

Add in your application.properties file:

#first db
spring.datasource.url = [url]
spring.datasource.username = [username]
spring.datasource.password = [password]
spring.datasource.driverClassName = oracle.jdbc.OracleDriver

#second db ...
spring.secondDatasource.url = [url]
spring.secondDatasource.username = [username]
spring.secondDatasource.password = [password]
spring.secondDatasource.driverClassName = oracle.jdbc.OracleDriver

Add in any class annotated with @Configuration the following methods:

@Bean
@Primary
@ConfigurationProperties(prefix="spring.datasource")
public DataSource primaryDataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
@ConfigurationProperties(prefix="spring.secondDatasource")
public DataSource secondaryDataSource() {
    return DataSourceBuilder.create().build();
}

As OMG Ponies stated, the having clause is what you are after. However, if you were hoping that you would get discrete rows instead of a summary (the "having" creates a summary) - it cannot be done in a single statement. You must use two statements in that case.

Few ideas, in my opinion only first one gives some guarantee:

1. Keep your secrets on some server on internet, and when needed just grab them and use. If user is about to use dropbox then nothing stops you from making request to your site and get your secret key.

2. Put your secrets in jni code, add some variable code to make your libraries bigger and more difficult to decompile. You might also split key string in few parts and keep them in various places.

3. use obfuscator, also put in code hashed secret and later on unhash it when needed to use.

4. Put your secret key as last pixels of one of your image in assets. Then when needed read it in your code. Obfuscating your code should help hide code that will read it.

I find the Code Metrics and Dependency Structure Matrix add-ins for Reflector very useful.

To extend Sean's great and concise answer with some sugar and modern syntax:

// date.js

const getMonthName = (num) => {
  const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Oct', 'Nov', 'Dec'];
  return months[num];
};

const formatDate = (d) => {
  const date = new Date(d);
  const year = date.getFullYear();
  const month = getMonthName(date.getMonth());
  const day = ('0' + date.getDate()).slice(-2);
  const hour = ('0' + date.getHours()).slice(-2);
  const minutes = ('0' + date.getMinutes()).slice(-2);

  return `${year} ${month} ${day}, ${hour}:${minutes}`;
};

module.exports = formatDate;

Then eg.

import formatDate = require('./date');

const myDate = "2018-07-24T13:44:46.493Z"; // Actual value from wherever, eg. MongoDB date
console.log(formatDate(myDate)); // 2018 Jul 24, 13:44

You haven't accepted an answer, so here's what worked for me in PuTTY:

Without allowing username changes, i got this question's subject as error on the gateway machine.

If you already know size of the char*, use this instead

char* data = ...;
int size = ...;
std::string myString(data, size);

This doesn't use strlen.

EDIT: If string variable already exists, use assign():

std::string myString;
char* data = ...;
int size = ...;
myString.assign(data, size);

If you're purely fetching data, it's a big help to performance when you tell EF to not keep track of the entities it fetches. Do this by using MergeOption.NoTracking. EF will just generate the query, execute it and deserialize the results to objects, but will not attempt to keep track of entity changes or anything of that nature. If a query is simple (doesn't spend much time waiting on the database to return), I've found that setting it to NoTracking can double query performance.

See this MSDN article on the MergeOption enum:

Identity Resolution, State Management, and Change Tracking

This seems to be a good article on EF performance:

Performance and the Entity Framework

In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.

Use daniel's solution if the set of encoded characters is relatively restricted. Otherwise, use one of the numerous HTML-parsing libraries.

I like BeautifulSoup because it can handle malformed XML/HTML :

http://www.crummy.com/software/BeautifulSoup/

for your question, there's an example in their documentation

from BeautifulSoup import BeautifulStoneSoup
BeautifulStoneSoup("Sacré bleu!", 
                   convertEntities=BeautifulStoneSoup.HTML_ENTITIES).contents[0]
# u'Sacr\xe9 bleu!'

I know @Martyn does not want full code, but I think this annotation its good for this question:

Foursquared for Android is open-source, and have an interesting code pattern interacting with the foursquare REST API.

I had this problem running unit tests (xunit) in Visual Studio 2015 and came across the following fix:

Menu Bar -> Test -> Test Settings -> Default Processor Architecture -> X64

Say you want to answer a request with a 204: No Content HTTP status. Firefox will complain with "no element found" in the console of the browser. This is a bug in Firefox that has been reported, but never fixed, for several years. By sending a "Content-type: text/plain" header, you can prevent this error in Firefox.

In Servlet do:

String selectedRole = "rat"; // Or "cat" or whatever you'd like.
request.setAttribute("selectedRole", selectedRole);

Then in JSP do:

<select name="roleName">
    <c:forEach items="${roleNames}" var="role">
        <option value="${role}" ${role == selectedRole ? 'selected' : ''}>${role}</option>
    </c:forEach>
</select>

It will print the selected attribute of the HTML <option> element so that you end up like:

<select name="roleName">
    <option value="cat">cat</option>
    <option value="rat" selected>rat</option>
    <option value="unicorn">unicorn</option>
</select>

Apart from the problem: this is not a combo box. This is a dropdown. A combo box is an editable dropdown.

Do this :

<script type="text/javascript">
function showDetails(username)
{
   window.location = '/player_detail?username='+username;
}
</script>

<input type="button" name="theButton" value="Detail" onclick="showDetails('username');">
