    x = x.setter(_x_set)
    x = x.deleter(_x_del)

Is the same as:

    def _x_get(self):
        return self._x
    x = property(_x_get, doc="I'm the 'x' property.")

Which is the same as :

    @property
    def x(self):
        """I'm the 'x' property."""

    @x.deleter

Completely untested, but this should work:

View positiveButton = findViewById(R.id.positiveButton);
RelativeLayout.LayoutParams layoutParams = 
    (RelativeLayout.LayoutParams)positiveButton.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
positiveButton.setLayoutParams(layoutParams);

add android:configChanges="orientation|screenSize" inside your activity in your manifest

The include tag

The <include> tag lets you to divide your layout into multiple files: it helps dealing with complex or overlong user interface.

Let's suppose you split your complex layout using two include files as follows:

top_level_activity.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <include layout="@layout/include1.xml" />

    <!-- Second include file -->
    <include layout="@layout/include2.xml" />

</LinearLayout>

Then you need to write include1.xml and include2.xml.

Keep in mind that the xml from the include files is simply dumped in your top_level_activity layout at rendering time (pretty much like the #INCLUDE macro for C).

The include files are plain jane layout xml.

include1.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textView1"
    android:text="First include"
    android:textAppearance="?android:attr/textAppearanceMedium"/>

... and include2.xml:

<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/button1"
    android:text="Button" />

See? Nothing fancy. Note that you still have to declare the android namespace with xmlns:android="http://schemas.android.com/apk/res/android.

So the rendered version of top_level_activity.xml is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <TextView
        android:id="@+id/textView1"
        android:text="First include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <!-- Second include file -->
    <Button
        android:id="@+id/button1"
        android:text="Button" />


</LinearLayout>

In your java code, all this is transparent: findViewById(R.id.textView1) in your activity class returns the correct widget ( even if that widget was declared in a xml file different from the activity layout).

And the cherry on top: the visual editor handles the thing swimmingly. The top level layout is rendered with the xml included.

The plot thickens

As an include file is a classic layout xml file, it means that it must have one top element. So in case your file needs to include more than one widget, you would have to use a layout.

Let's say that include1.xml has now two TextView: a layout has to be declared. Let's choose a LinearLayout.

include1.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout2" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

</LinearLayout>

The top_level_activity.xml will be rendered as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <LinearLayout 
        android:id="@+id/layout2" 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

       <TextView
            android:id="@+id/textView1"
            android:text="Second include"
            android:textAppearance="?android:attr/textAppearanceMedium"/>

       <TextView
            android:id="@+id/textView2"
            android:text="More text"
            android:textAppearance="?android:attr/textAppearanceMedium"/>

   </LinearLayout>

     <!-- Second include file -->
   <Button
        android:id="@+id/button1"
        android:text="Button" />

</LinearLayout>

But wait the two levels of LinearLayout are redundant!

Indeed, the two nested LinearLayout serve no purpose as the two TextView could be included under layout1for exactly the same rendering.

So what can we do?

Enter the merge tag

The <merge> tag is just a dummy tag that provides a top level element to deal with this kind of redundancy issues.

Now include1.xml becomes:

<merge xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

</merge>

and now top_level_activity.xml is rendered as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file --> 
    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <!-- Second include file -->
    <Button
        android:id="@+id/button1"
        android:text="Button" />

</LinearLayout>

You saved one hierarchy level, avoid one useless view: Romain Guy sleeps better already.

Aren't you happier now?

@Vigril Disgr4ce

When it comes to multi field forms, it makes sense to use React's key feature: components.

In my projects, I create TextField components, that take a value prop at minimum, and it takes care of handling common behaviors of an input text field. This way you don't have to worry about keeping track of field names when updating the value state.

[...]

handleChange: function(event) {
  this.setState({value: event.target.value});
},
render: function() {
  var value = this.state.value;
  return <input type="text" value={value} onChange={this.handleChange} />;
}

[...]

Looks like you're already using request module.

in this case all you need to post multipart/form-data is to use its form feature:

var req = request.post(url, function (err, resp, body) {
  if (err) {
    console.log('Error!');
  } else {
    console.log('URL: ' + body);
  }
});
var form = req.form();
form.append('file', '<FILE_DATA>', {
  filename: 'myfile.txt',
  contentType: 'text/plain'
});

but if you want to post some existing file from your file system, then you may simply pass it as a readable stream:

form.append('file', fs.createReadStream(filepath));

request will extract all related metadata by itself.

For more information on posting multipart/form-data see node-form-data module, which is internally used by request.

The u- prefix just means that you have a Unicode string. When you really use the string, it won't appear in your data. Don't be thrown by the printed output.

For example, try this:

print mail_accounts[0]["i"]

You won't see a u.

This looks like what you actually want. It applies the same approach of this answer to your specific case:

import matplotlib.pyplot as plt

fig, ax = plt.subplots(nrows=3, ncols=3, sharex=True, sharey=True, figsize=(6, 6))

fig.text(0.5, 0.04, 'common X', ha='center')
fig.text(0.04, 0.5, 'common Y', va='center', rotation='vertical')

I made this work by importing datetime as realdatetime and replacing the methods I needed in the mock with the real methods:

import datetime as realdatetime

@mock.patch('datetime')
def test_method(self, mock_datetime):
    mock_datetime.today = realdatetime.today
    mock_datetime.now.return_value = realdatetime.datetime(2019, 8, 23, 14, 34, 8, 0)

if you want to follow Android 10 practices to write in storage, check here and if you only want the images to be app specific, here for example if you want to store an image just to be used by your app:

viewModelScope.launch(Dispatchers.IO) {
            getApplication<Application>().openFileOutput(filename, Context.MODE_PRIVATE).use {
                bitmap.compress(Bitmap.CompressFormat.PNG, 50, it)
            }
        }

getApplication is a method to give you context for ViewModel and it's part of AndroidViewModel later if you want to read it:

viewModelScope.launch(Dispatchers.IO) {
            val savedBitmap = BitmapFactory.decodeStream(
                getApplication<App>().openFileInput(filename).readBytes().inputStream()
            )
        }

To undo your last commit, simply do git reset --hard HEAD~.

Edit: this answer applied to an earlier version of the question that did not mention preserving local changes; the accepted answer from Tim is indeed the correct one. Thanks to qwertzguy for the heads up.

You can find a really good boilerplate made by Henrik Joreteg (ampersandjs) here: https://github.com/HenrikJoreteg/hjs-webpack

Then in your webpack.config.js

var getConfig = require('hjs-webpack')

module.exports = getConfig({
  in: 'src/index.js',
  out: 'public',
  clearBeforeBuild: true,
  https: process.argv.indexOf('--https') !== -1
})

Ports

The ports section will publish ports on the host. Docker will setup a forward for a specific port from the host network into the container. By default this is implemented with a userspace proxy process (docker-proxy) that listens on the first port, and forwards into the container, which needs to listen on the second point. If the container is not listening on the destination port, you will still see something listening on the host, but get a connection refused if you try to connect to that host port, from the failed forward into your container.

Note, the container must be listening on all network interfaces since this proxy is not running within the container's network namespace and cannot reach 127.0.0.1 inside the container. The IPv4 method for that is to configure your application to listen on 0.0.0.0.

Also note that published ports do not work in the opposite direction. You cannot connect to a service on the host from the container by publishing a port. Instead you'll find docker errors trying to listen to the already-in-use host port.

Expose

Expose is documentation. It sets metadata on the image, and when running, on the container too. Typically you configure this in the Dockerfile with the EXPOSE instruction, and it serves as documentation for the users running your image, for them to know on which ports by default your application will be listening. When configured with a compose file, this metadata is only set on the container. You can see the exposed ports when you run a docker inspect on the image or container.

There are a few tools that rely on exposed ports. In docker, the -P flag will publish all exposed ports onto ephemeral ports on the host. There are also various reverse proxies that will default to using an exposed port when sending traffic to your application if you do not explicitly set the container port.

Other than those external tools, expose has no impact at all on the networking between containers. You only need a common docker network, and connecting to the container port, to access one container from another. If that network is user created (e.g. not the default bridge network named bridge), you can use DNS to connect to the other containers.

I have figured out a solution to this problem. We can build a Function or View with "rendered" sql in a stored procedure that can then be executed as normal.

1.Create another sproc

CREATE PROCEDURE [dbo].[usp_FunctionBuilder]
DECLARE @outerSql VARCHAR(MAX)
DECLARE @innerSql VARCHAR(MAX)

2.Build the dynamic sql that you want to execute in your function (Example: you could use a loop and union, you could read in another sproc, use if statements and parameters for conditional sql, etc.)

SET @innerSql = 'your sql'

3.Wrap the @innerSql in a create function statement and define any external parameters that you have used in the @innerSql so they can be passed into the generated function.

SET @outerSql = 'CREATE FUNCTION [dbo].[fn_GeneratedFunction] ( @Param varchar(10))
RETURNS TABLE
AS
RETURN
' + @innerSql;


EXEC(@outerSql)

This is just pseudocode but the solution solves many problems such as linked server limitations, parameters, dynamic sql in function, dynamic server/database/table name, loops, etc.

You will need to tweak it to your needs, (Example: changing the return in the function)

I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):

    public ActionResult ExportToExcel()
    {
        var products = new System.Data.DataTable("teste");
        products.Columns.Add("col1", typeof(int));
        products.Columns.Add("col2", typeof(string));

        products.Rows.Add(1, "product 1");
        products.Rows.Add(2, "product 2");
        products.Rows.Add(3, "product 3");
        products.Rows.Add(4, "product 4");
        products.Rows.Add(5, "product 5");
        products.Rows.Add(6, "product 6");
        products.Rows.Add(7, "product 7");


        var grid = new GridView();
        grid.DataSource = products;
        grid.DataBind();

        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
        Response.ContentType = "application/ms-excel";

        Response.Charset = "";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

        grid.RenderControl(htw);

        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();

        return View("MyView");
    }

To remove all array elements irrespective of any given id, use this:

collection.update(
  { },
  { $pull: { 'contact.phone': { number: '+1786543589455' } } }
);

Do this:

date('Y-m-d', strtotime('dd/mm/yyyy'));

But make sure 'dd/mm/yyyy' is the actual date.

Recently I was trying to detect the home press button, because I needed it to do the same as the method "onBackPressed()". In order to do this, I had to override the method "onSupportNavigateUp()" like this:

override fun onSupportNavigateUp(): Boolean {
    onBackPressed()
    return true
}

It worked perfectly. =)

**Set proper alias name**
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509","BC");
            X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(derInputStream);
            String alias = cert.getSubjectX500Principal().getName();
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
            trustStore.load(null);
trustStore.setCertificateEntry(alias, cert);

i saw this error when i was trying to send a form, and in one of the fields' names, i let the word "endereço".

echo form_input(array('class' => 'form-control', 'name' => 'endereco', 'placeholder' => 'Endereço', 'value' => set_value('endereco')));

When i changed 'ç' for 'c', the error was gone.

This is one of the huge benefits of using the machine.config. At my last job, we had development, test and production environments. We could use the machine.config for things like connection strings (to the appropriate, dev/test/prod SQL machine).

This may not be a solution for you if you don't have access to the actual production machine (like, if you were using a hosting company on a shared host).

Remember, if you have a string which was read as a line from a text file using the fgets() function, you need to use substr($string, -3, 1) so that you get the actual character and not part of the CRLF (Carriage Return Line Feed).

I don't think the person who asked the question needed this, but for me, I was having trouble getting that last character from a string from a text file so I'm sure others will come across similar problems.

The only benefit for the option B is having all the data in one system, yet it's a false benefit! You may argue that your code is also a form of data, and therefore also can be stored in database - how would you like it?

Unless you have some unique case:

• Business logic belongs in code.
• Structured data belongs in database (relational or non-relational).
• Bulk data belongs in storage (filesystem or other).

It is not necessary to use filesystem to keep files. Instead you may use cloud storage (such as Amazon S3) or Infrastructure-as-a-service on top of it (such as Uploadcare):

https://uploadcare.com/upload-api-cloud-storage-and-cdn/

But storing files in the database is a bad idea.

An earlier process of resolving conflicts (through the staging view) in Eclipse seemed much more intuitive several years ago, so either the tooling no longer functions in the way that I was used to, or I am remembering the process of resolving merge conflicts within SVN repositories. Regardless, there was this nifty "Mark as Merged" menu option when right-clicking on a conflicting file.

Fast forward to 2019, I am using the "Git Staging" view in Eclipse (v4.11). Actually, I am using STS (Spring Tool Suite 3.9.8), but I think the Git Staging view is a standard Eclipse plugin for working with Java/Spring-based projects. I share the following approach in case it helps anyone else, and because I grow weary or resolving merge conflicts from the GIT command line. ;-)

Because the feature I recall is now gone (or perhaps done differently with the current version of GIT and Eclipse), here are the current steps that I now follow to resolve merge conflicts through Eclipse using a GIT repository. It seems the most intuitive to me. Obviously, it is clear from the number of responses here that there are many ways to resolve merge conflicts. Perhaps I just need to switch to JetBrains IntelliJ, with their three-way merge tool.

1. Double-click on the offending file
2. A "Text Compare" interface appears, with side-by-side views of the conflicting commits.
3. Identify which view is the local state of the file, or the most recent commit.
4. Make changes to the local window, either adding or redacting the changes from the offending commit.
5. When the desired set of changes has been reviewed and updated, right-click on the unstaged file.
6. Click the "Add to Index" option, and your file will be added to the staged changes.
7. This also removes the conflicting file from the unstaged list, thus indicating that it has been "marked as merged"
8. Continue this process with each additional file in conflict.
9. When you have reivewed all conflicting files, confirm that all desired files (including additional changes) are staged.
10. Add an appropriate commit message.
11. Commit and push the "merged" files to the origin repository, and this officially marks your files as merged.

NOTE: Because the menu options are not intuitive, a number of things can be misleading. For example, if you have saved any updates locally, and try to reopen the conflicting file to confirmand that the changes you made have persisted, confusion may result since the original conflict state is opened... not your changes.

But once you add the file(s) to the index, you will see your changes there.

I also recommend that when you pull in changes that result in a merge conflict, that you "stash" your local changes first, and then pull the changes in again. At least with GIT, as a protection, you will not be allowed to pull in external changes until you either revert your changes or stash them. Discard and revert to the HEAD state if the changes are not important, but stash them otherwise.

Finally, if you have just one or two files changing, then consider pulling them into separate text files as a reference, then revert to the HEAD and then manually update the file(s) when you pull changes across.

The quickest solution to your problem I believe is that you simply are missing parentheses on your getText. Simply add () to edit.getText().toString() and that should solve it

Right-click (or control-click) the application in question and choose "Open"

for string sorting in case some one needs it,

const dataArr = {_x000D_
_x000D_
  "hello": [{_x000D_
    "id": 114,_x000D_
    "keyword": "zzzzzz",_x000D_
    "region": "Sri Lanka",_x000D_
    "supportGroup": "administrators",_x000D_
    "category": "Category2"_x000D_
  }, {_x000D_
    "id": 115,_x000D_
    "keyword": "aaaaa",_x000D_
    "region": "Japan",_x000D_
    "supportGroup": "developers",_x000D_
    "category": "Category2"_x000D_
  }]_x000D_
_x000D_
};_x000D_
const sortArray = dataArr['hello'];_x000D_
_x000D_
console.log(sortArray.sort((a, b) => {_x000D_
  if (a.region < b.region)_x000D_
    return -1;_x000D_
  if (a.region > b.region)_x000D_
    return 1;_x000D_
  return 0;_x000D_
}));

You can do it with anchor tags using css3 :target pseudo-selector, this selector is going to be triggered when the element with the same id as the hash of the current URL get an match. Example

Knowing this, we can combine this technique with the use of proximity selectors like "+" and "~" to select any other element through the target element who id get match with the hash of the current url. An example of this would be something like what you are asking.

You can pass the event as argument to the function and then prevent the default behaviour.

var OnSubmitTest = React.createClass({
        render: function() {
        doSomething = function(event){
           event.preventDefault();
           alert('it works!');
        }

        return <form onSubmit={this.doSomething}>
        <button>Click me</button>
        </form>;
    }
});

Interface is a contract you should comply to or given to, depending if you are implementer or a user.

This is what I use:

    private void ExpireAllCookies()
    {
        if (HttpContext.Current != null)
        {
            int cookieCount = HttpContext.Current.Request.Cookies.Count;
            for (var i = 0; i < cookieCount; i++)
            {
                var cookie = HttpContext.Current.Request.Cookies[i];
                if (cookie != null)
                {
                    var expiredCookie = new HttpCookie(cookie.Name) {
                        Expires = DateTime.Now.AddDays(-1),
                        Domain = cookie.Domain
                    };
                    HttpContext.Current.Response.Cookies.Add(expiredCookie); // overwrite it
                }
            }

            // clear cookies server side
            HttpContext.Current.Request.Cookies.Clear();
        }
    }

To skip . & .., you can use Dir::each_child.

Dir.each_child('/path/to/dir') do |filename|
  puts filename
end

Dir::children returns an array of the filenames.

Use https://prestodb.io/docs/current/connector/kafka-tutorial.html

A super SQL engine, provided by Facebook, that connects on several data sources (Cassandra, Kafka, JMX, Redis ...).

PrestoDB is running as a server with optional workers (there is a standalone mode without extra workers), then you use a small executable JAR (called presto CLI) to make queries.

Once you have configured well the Presto server , you can use traditionnal SQL:

SELECT count(*) FROM TOPIC_NAME;

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>

You have to put a g at the end, it stands for "global":

echo dog dog dos | sed -r 's:dog:log:g'
                                     ^

This is designed for use when you have a shell script build step. Use only the first two lines to get the file name.

You can get the console log file (using bash magic) for the current build from a shell script this way and check it for some error string, failing the job if found:

logFilename=${JENKINS_HOME}/${JOB_URL:${#JENKINS_URL}}
logFilename=${logFilename//job\//jobs\/}builds/${BUILD_NUMBER}/log

grep "**Failure**" ${logFilename} ; exitCode=$?
[[ $exitCode -ne 1 ]] && exit 1

You have to build the file name by taking the JOB_URL, stripping off the leading host name part, adding in the path to JENKINS_HOME, replacing "/job/" to "/jobs/" to handle all nested folders, adding the current build number and the file name.

The grep returns 0 if the string is found and 2 if there is a file error. So a 1 means it found the error indication string. That makes the build fail.

For python3.5.3, pip3 is also installed when you install python. When you install it you may not select the add to path. Then you can find where the pip3 located and add it to path manually.

Another possibility with Guava:

dependency: compile 'com.google.guava:guava:11.0.2'

import com.google.common.io.ByteStreams;
...

String total = new String(ByteStreams.toByteArray(inputStream ));

Jackson and Gson are the most complete Java JSON packages regarding actual data binding support; many other packages only provide primitive Map/List (or equivalent tree model) binding. Both have complete support for generic types, as well, as enough configurability for many common use cases.

Since I am more familiar with Jackson, here are some aspects where I think Jackson has more complete support than Gson (apologies if I miss a Gson feature):

• Extensive annotation support; including full inheritance, and advanced "mix-in" annotations (associate annotations with a class for cases where you can not directly add them)
• Streaming (incremental) reading, writing, for ultra-high performance (or memory-limited) use cases; can mix with data binding (bind sub-trees) -- EDIT: latest versions of Gson also include streaming reader
• Tree model (DOM-like access); can convert between various models (tree <-> java object <-> stream)
• Can use any constructors (or static factory methods), not just default constructor
• Field and getter/setter access (earlier gson versions only used fields, this may have changed)
• Out-of-box JAX-RS support
• Interoperability: can also use JAXB annotations, has support/work-arounds for common packages (joda, ibatis, cglib), JVM languages (groovy, clojure, scala)
• Ability to force static (declared) type handling for output
• Support for deserializing polymorphic types (Jackson 1.5) -- can serialize AND deserialize things like List correctly (with additional type information)
• Integrated support for binary content (base64 to/from JSON Strings)

For those that want a nice conditional:

DECLARE @MyDate DATETIME  = 'some date in future' --example  DateAdd(day,5,GetDate())

IF @MyDate < DATEADD(DAY,1,GETDATE())
    BEGIN
        PRINT 'Date NOT greater than today...'
END
ELSE 
    BEGIN
       PRINT 'Date greater than today...'
END 

-> is for pointers to a class instance

. is for class instances

:: is for classnames - for example when using a static member

No, it won't, unless you do some work.

The important part here is what DEBUG really is, and it's a kind of constant defined that the compiler can check against.

If you check the project properties, under the Build tab, you'll find three things:

• A text box labelled "Conditional compilation symbols"
• A check box labelled "Define DEBUG constant"
• A check box labelled "Define TRACE constant"

There is no such checkbox, nor constant/symbol pre-defined that has the name RELEASE.

However, you can easily add that name to the text box labelled Conditional compilation symbols, but make sure you set the project configuration to Release-mode before doing so, as these settings are per configuration.

So basically, unless you add that to the text box, #if RELEASE won't produce any code under any configuration.

This is because your servlet is trying to access a request object which is no more exist.. A servlet's forward or include statement does not stop execution of method block. It continues to the end of method block or first return statement just like any other java method.

The best way to resolve this problem just set the page (where you suppose to forward the request) dynamically according your logic. That is:

protected void doPost(request , response){
String returnPage="default.jsp";
if(condition1){
 returnPage="page1.jsp";
}
if(condition2){
   returnPage="page2.jsp";
}
request.getRequestDispatcher(returnPage).forward(request,response); //at last line
}

and do the forward only once at last line...

you can also fix this problem using return statement after each forward() or put each forward() in if...else block

You need to use the CONCAT() function in MySQL for string concatenation:

UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;

You need the "correlation id" (the "AS SS" thingy) on the sub-select to reference the fields in the "ON" condition. The id's assigned inside the sub select are not usable in the join.

SELECT
       cs.CUSID
       ,dp.DEPID
FROM
    CUSTMR cs
        LEFT OUTER JOIN (
            SELECT
                    DEPID
                    ,DEPNAME
                FROM
                    DEPRMNT 
                WHERE
                    dp.DEPADDRESS = 'TOKYO'
        ) ss
            ON (
                ss.DEPID = cs.CUSID
                AND ss.DEPNAME = cs.CUSTNAME
            )
WHERE
    cs.CUSID != '' 

<div class="parent" style="height:500px;">
<div class="child-left floatLeft" style="height:100%">
</div>

<div class="child-right floatLeft" style="height:100%">
</div>
</div>

I used inline style just to give idea.

Make sure you have this code on you component:

export class Component {
  checked = true;
}

This is a solution suggested by the MySQl manual:

If expr is given as an argument to LAST_INSERT_ID(), the value of the argument is returned by the function and is remembered as the next value to be returned by LAST_INSERT_ID(). This can be used to simulate sequences:

Create a table to hold the sequence counter and initialize it:

    mysql> CREATE TABLE sequence (id INT NOT NULL);
    mysql> INSERT INTO sequence VALUES (0);

Use the table to generate sequence numbers like this:

    mysql> UPDATE sequence SET id=LAST_INSERT_ID(id+1);
    mysql> SELECT LAST_INSERT_ID();

The UPDATE statement increments the sequence counter and causes the next call to LAST_INSERT_ID() to return the updated value. The SELECT statement retrieves that value. The mysql_insert_id() C API function can also be used to get the value. See Section 23.8.7.37, “mysql_insert_id()”.

You can generate sequences without calling LAST_INSERT_ID(), but the utility of using the function this way is that the ID value is maintained in the server as the last automatically generated value. It is multi-user safe because multiple clients can issue the UPDATE statement and get their own sequence value with the SELECT statement (or mysql_insert_id()), without affecting or being affected by other clients that generate their own sequence values.

Rules are used to enhance the behaviour of each test method in a generic way. Junit rule intercept the test method and allows us to do something before a test method starts execution and after a test method has been executed.

For example, Using @Timeout rule we can set the timeout for all the tests.

public class TestApp {
    @Rule
    public Timeout globalTimeout = new Timeout(20, TimeUnit.MILLISECONDS);

    ......
    ......

 }

@TemporaryFolder rule is used to create temporary folders, files. Every time the test method is executed, a temporary folder is created and it gets deleted after the execution of the method.

public class TempFolderTest {

 @Rule
 public TemporaryFolder tempFolder= new TemporaryFolder();

 @Test
 public void testTempFolder() throws IOException {
  File folder = tempFolder.newFolder("demos");
  File file = tempFolder.newFile("Hello.txt");

  assertEquals(folder.getName(), "demos");
  assertEquals(file.getName(), "Hello.txt");

 }


}

You can see examples of some in-built rules provided by junit at this link.

Try this:

return Redirect("http://www.website.com");

Also:

func getTime() -> (hour: Int, minute: Int,second: Int) {
    let hour = 1
    let minute = 2
    let second = 3
    return ( hour, minute, second)
}

Then it's invoked as:

let time = getTime()
print("hour: \(time.hour), minute: \(time.minute), second: \(time.second)")

This is the standard way how to use it in the book The Swift Programming Language written by Apple.

or just like:

let time = getTime()
print("hour: \(time.0), minute: \(time.1), second: \(time.2)")

it's the same but less clearly.

If trigger("chosen:updated"); not working, use .trigger("liszt:updated"); of @Nhan Tran it is working fine.

RESTful does not recommend using verbs in URL's /cars/search is not restful. The right way to filter/search/paginate your API's is through Query Parameters. However there might be cases when you have to break the norm. For example, if you are searching across multiple resources, then you have to use something like /search?q=query

You can go through http://saipraveenblog.wordpress.com/2014/09/29/rest-api-best-practices/ to understand the best practices for designing RESTful API's

As always in python, there are of course several ways to do it, but there is one obvious way to do it.

tmpdict["ONE"]["TWO"]["THREE"] is the obvious way to do it.

When that does not fit well with your algorithm, that may be a hint that your structure is not the best for the problem.

If you just want to just save you repetative typing, you can of course alias a subset of the dict:

>>> two_dict = tmpdict['ONE']['TWO'] # now you can just write two_dict for tmpdict['ONE']['TWO']
>>> two_dict["spam"] = 23
>>> tmpdict
{'ONE': {'TWO': {'THREE': 10, 'spam': 23}}}

I used to use the PGP disk encryption product on a laptop (and ran NTFS compressed on top of that!). It didn't seem to have much effect if the amount of disk to be read was small; and most software sources aren't huge by disk standards.

You have lots of RAM and pretty fast processors. I spent most of my time thinking, typing or debugging.

I wouldn't worry very much about it.

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

try this....

I'm partial to AdeptSQL. It's clean and intuitive and it DOESN'T have the one feature that scares the hell out of me on a lot of similar programs. One giant button that it you push it will automatically synchronize EVERYTHING without so much as a by-your-leave. If you want to sync the changes you have to do it yourself and I like that.

In our case we had a query which loads multiple items with select * from x where something in (...) The in part was so long for benchmark test.(17mb as text query). Query is valid but text so long. Shortening the query solved the problem.

I also got this error, was not having any clue. I could see the class and jars in Target folder. I later installed Maven 3.5, switched my local repo from C drive to other drive through conf/settings.xml of Maven. It worked perfectly fine after that. I think having local repo in C drive was main issue. Even though repo was having full access.

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

Oh, that's an interesting beast.

I've spent considerable time of getting that right, there are three main issues that differs from locale to locale: - currency symbol and direction - thousand separator - decimal point

I've written my own rather extensive implementation of this which is part of the kiwi python framework, check out the LGPL:ed source here:

http://svn.async.com.br/cgi-bin/viewvc.cgi/kiwi/trunk/kiwi/currency.py?view=markup

The code is slightly Linux/Glibc specific, but shouldn't be too difficult to adopt to windows or other unixes.

Once you have that installed you can do the following:

>>> from kiwi.datatypes import currency
>>> v = currency('10.5').format()

Which will then give you:

'$10.50'

or

'10,50 kr'

Depending on the currently selected locale.

The main point this post has over the other is that it will work with older versions of python. locale.currency was introduced in python 2.5.

In this sample, I created a JavaScript progress bar (with percentage display), you can control it and hide it with JavaScript.

In this sample, the progress bar advances every 100ms. You can see it in JSFiddle

var elapsedTime = 0;
var interval = setInterval(function() {
  timer()
}, 100);

function progressbar(percent) {
  document.getElementById("prgsbarcolor").style.width = percent + '%';
  document.getElementById("prgsbartext").innerHTML = percent + '%';
}

function timer() {
  if (elapsedTime > 100) {
    document.getElementById("prgsbartext").style.color = "#FFF";
    document.getElementById("prgsbartext").innerHTML = "Completed.";
    if (elapsedTime >= 107) {
      clearInterval(interval);
      history.go(-1);
    }
  } else {
    progressbar(elapsedTime);
  }
  elapsedTime++;
}

[cell setSelectionStyle:UITableViewCellSelectionStyleGray];

Make sure you have used the above line to use the selection effect

w3school offered this way:

echo nl2br("One line.\n Another line.");

by use of this function you can do it..i tried other ways that said above but they wont help me..

Also consider using Array(). From the Ruby Community Style Guide:

Use Array() instead of explicit Array check or [*var], when dealing with a variable you want to treat as an Array, but you're not certain it's an array.

# bad
paths = [paths] unless paths.is_a? Array
paths.each { |path| do_something(path) }

# bad (always creates a new Array instance)
[*paths].each { |path| do_something(path) }

# good (and a bit more readable)
Array(paths).each { |path| do_something(path) }

I need to add a header to categorize the list item in Drawer

Customize the listView or use expandableListView

I need a radio button to select some of my options

You can do that without modifying the current implementation of NavigationDrawer, You just need to create a custom adapter for your listView. You can add a parent layout as Drawer then you can do any complex layouts within that as normal.

Use the following code for refreshing fragment again:

FragmentTransaction ftr = getFragmentManager().beginTransaction();                          
ftr.detach(EnterYourFragmentName.this).attach(EnterYourFragmentName.this).commit();

If you are using Java, you could just replace the x00 characters before the insert like following:

myValue.replaceAll("\u0000", "")

The solution was provided and explained by Csaba in following post:

https://www.postgresql.org/message-id/1171970019.3101.328.camel%40coppola.muc.ecircle.de

Respectively:

in Java you can actually have a "0x0" character in your string, and that's valid unicode. So that's translated to the character 0x0 in UTF8, which in turn is not accepted because the server uses null terminated strings... so the only way is to make sure your strings don't contain the character '\u0000'.

Just delete the ".project" file in your project folder (it's hidden on Linux, use "ls -a" to show), then from Eclipse, choose Create Android Project from existing source

Solution - I removed the height and width elements of the img and then the alt text worked.

<img src="smiley.gif" alt="Smiley face" width="32" height="32" />

#define FOO(fmt, ...) printf(fmt, ##__VA_ARGS__)

I reworked the example you provided in the js fiddle : http://jsfiddle.net/zravs3hp/

Step 1 :

I renamed your container div to overlay, as semantically this div is not a container, but an overlay. I also placed the loader div as a child of this overlay div.

The resulting html is :

<div class="overlay">
    <div id="loading-img"></div>
</div>


<div class="content">
    <div>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ea velit provident sint aliquid eos omnis aperiam officia architecto error incidunt nemo obcaecati adipisci doloremque dicta neque placeat natus beatae cupiditate minima ipsam quaerat explicabo non reiciendis qui sit. ...</div>
    <button id="button">Submit</button>
</div>

The css of the overlay is the following

.overlay {
    background: #e9e9e9;  <- I left your 'gray' background
    display: none;        <- Not displayed by default
    position: absolute;   <- This and the following properties will
    top: 0;                  make the overlay, the element will expand
    right: 0;                so as to cover the whole body of the page
    bottom: 0;
    left: 0;
    opacity: 0.5;
}

Step 2 :

I added some dummy text so as to have something to overlay.

Step 3 :

Then, in the click handler we just need to show the overlay :

$("#button").click(function () {
    $(".overlay").show();
});

For getting a list of int from an enum, use the following. It works!

List<int> listEnumValues = new List<int>();
YourEnumType[] myEnumMembers = (YourEnumType[])Enum.GetValues(typeof(YourEnumType));
foreach ( YourEnumType enumMember in myEnumMembers)
{
    listEnumValues.Add(enumMember.GetHashCode());
}

I wanted to use Font Awesome 5+ and most answers focus on older versions

For the new Font Awesome 5+ the angular project hasn't been released yet, so if you want to make use of the examples mentioned on the font awesome website atm you need to use a work around. (especially the fas, far classes instead of the fa class)

I've just imported the cdn to Font Awesome 5 in my styles.css. Just added this in case it helps someone find the answer quicker than I did :-)

Code in Style.css

@import "https://use.fontawesome.com/releases/v5.0.7/css/all.css";

import java.io.IOException;
import java.lang.ProcessBuilder;

public class handlingexe {
    public static void main(String[] args) throws IOException {
        ProcessBuilder p = new ProcessBuilder();
        System.out.println("Started EXE");
        p.command("C:\\Users\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe");   

        p.start();
        System.out.println("Started EXE"); 
    }
}

tl;dr: use OSX's native process launcher and manager, launchd.

To do so, make a launchctl daemon. You'll have full control over all aspects of the script. You can run once or keep alive as a daemon. In most cases, this is the way to go.

1. Create a .plist file according to the instructions in the Apple Dev docs here or more detail below.
2. Place in ~/Library/LaunchAgents
3. Log in (or run manually via launchctl load [filename.plist])

For more on launchd, the wikipedia article is quite good and describes the system and its advantages over other older systems.

Here's the specific plist file to run a script at login.

Updated 2017/09/25 for OSX El Capitan and newer (credit to José Messias Jr):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
   <key>Label</key>
   <string>com.user.loginscript</string>
   <key>ProgramArguments</key>
   <array><string>/path/to/executable/script.sh</string></array>
   <key>RunAtLoad</key>
   <true/>
</dict>
</plist>

Replace the <string> after the Program key with your desired command (note that any script referenced by that command must be executable: chmod a+x /path/to/executable/script.sh to ensure it is for all users).

Save as ~/Library/LaunchAgents/com.user.loginscript.plist

Run launchctl load ~/Library/LaunchAgents/com.user.loginscript.plist and log out/in to test (or to test directly, run launchctl start com.user.loginscript)

Tail /var/log/system.log for error messages.

The key is that this is a User-specific launchd entry, so it will be run on login for the given user. System-specific launch daemons (placed in /Library/LaunchDaemons) are run on boot.

If you want a script to run on login for all users, I believe LoginHook is your only option, and that's probably the reason it exists.

I had same issue as I had missed adding composeEnhancers. Once this is setup then you can take a look into action creators. You get this error when this is not setup as well.

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

const store = createStore(
  rootReducer,
  composeEnhancers(applyMiddleware(thunk))
);

Use another constant instead of Calendar.HOUR, use Calendar.HOUR_OF_DAY.

calendar.set(Calendar.HOUR_OF_DAY, 0);

Calendar.HOUR uses 0-11 (for use with AM/PM), and Calendar.HOUR_OF_DAY uses 0-23.

To quote the Javadocs:

public static final int HOUR

Field number for get and set indicating the hour of the morning or afternoon. HOUR is used for the 12-hour clock (0 - 11). Noon and midnight are represented by 0, not by 12. E.g., at 10:04:15.250 PM the HOUR is 10.

and

public static final int HOUR_OF_DAY

Field number for get and set indicating the hour of the day. HOUR_OF_DAY is used for the 24-hour clock. E.g., at 10:04:15.250 PM the HOUR_OF_DAY is 22.

Testing ("now" is currently c. 14:55 on July 23, 2013 Pacific Daylight Time):

public class Main
{
   static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    public static void main(String[] args)
    {
        Calendar now = Calendar.getInstance();
        now.set(Calendar.HOUR, 0);
        now.set(Calendar.MINUTE, 0);

        now.set(Calendar.HOUR_OF_DAY, 0);

You are able to choose one that you like, but it has to be unique.

Every time I have to enter the SKU I use the App identifier (e.g. de.mycompany.myappname) because this is already unique.

Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax() method. Or if you wanted to do it using plain javascript, here's a tutorial.

Make sure your code is in DOM Ready as pointed by rocket-hazmat

.click()

$('#RootNode').click(function(){
  //do something
});

document.getElementById("RootNode").onclick = function(){//do something}

Use event Delegation/

$(document).on("click", "#RootNode", function(){
   //do something
});

Wrap Code in Dom Ready

$(document).ready(function(){
    $('#RootNode').click(function(){
     //do something
    });
});

for those who got here because the title of the question:

I use Reply-To: address with webforms. when someone fills out the form, the webpage sends an automatic email to the page's owner. the From: is the automatic mail sender's address, so the owner knows it is from the webform. but the Reply-To: address is the one filled in in the form by the user, so the owner can just hit reply to contact them.

Muppy is (yet another) Memory Usage Profiler for Python. The focus of this toolset is laid on the identification of memory leaks.

Muppy tries to help developers to identity memory leaks of Python applications. It enables the tracking of memory usage during runtime and the identification of objects which are leaking. Additionally, tools are provided which allow to locate the source of not released objects.

Always mark as source root the directory ABOVE the import!

So if the structure is

parent_folder/src/module.py

you must put something like:

from src.module import function_inside_module

and have parent_folder marked as "source folder" in PyCharm

This is also simple crossbrowser solution:

var addEvent =  window.attachEvent||window.addEventListener;
var event = window.attachEvent ? 'onclick' : 'click';
addEvent(event, function(){
    alert('Hello!')
});

Instead of 'click' can be any event of course.

SELECT e.*,
       cnt.colCount 
FROM eventsTable e
INNER JOIN (
           select columnName,count(columnName) as colCount
           from eventsTable e2 
          group by columnName
           ) as cnt on cnt.columnName = e.columnName
WHERE e.columnName='Business'

-- Added space

The following syntax can also be used if the array is not named (just the array is passed to the template):

  <ul id="luke_should_be_here">
  {{this.1.name}}
  </ul>

This far I've found this one is working, having to set a Timeout of 1ms for the action to complete after chrome's auto-filling ..

$(window).on('load', function() {
    setTimeout(function(){
        $('input[name*=email],input[name*=Password]').val('-').val(null);
    },1);
});

I'm wondering if there's any way of attaching this function to chrome self-completion firing, or even, redeclaring it

Try this:

UPDATE test
SET
   field = 1
WHERE id = 123 and condition

Try this small example:

Code:

try {
    Path tmpDir = Files.createTempDirectory("tmpDir");
    System.out.println(tmpDir.toString());
    Files.delete(tmpDir);
} catch (IOException e) {
    e.printStackTrace();
}

Imports:
java.io.IOException
java.nio.file.Files
java.nio.file.Path

Console output on Windows machine:
C:\Users\userName\AppData\Local\Temp\tmpDir2908538301081367877

Comment:
Files.createTempDirectory generates unique ID atomatically - 2908538301081367877.

I had the same issue after I upgraded my JDK from 1.7 to 1.8. I'm using Eclipse 4.4 (Luna). The error is gone after I degrade JDK to 1.7.

I was using it in subquery and it returned me same rows in subquery

 SELECT  ID ,
            ( SELECT TOP 1
                        ImageURL
              FROM      SubTable 
              ORDER BY  NEWID()
            ) AS ImageURL,
            GETUTCDATE() ,
            1
    FROM    Mytable

then i solved with including parent table variable in where

SELECT  ID ,
            ( SELECT TOP 1
                        ImageURL
              FROM      SubTable 
              Where Mytable.ID>0
              ORDER BY  NEWID()
            ) AS ImageURL,
            GETUTCDATE() ,
            1
    FROM    Mytable

Note the where condtition

The next step would be FisherFaces. Try it and check whether they work for you. Here is a nice comparison.

I have a few suggestions:

• If your nodes are configured to have 6g maximum for Spark (and are leaving a little for other processes), then use 6g rather than 4g, spark.executor.memory=6g. Make sure you're using as much memory as possible by checking the UI (it will say how much mem you're using)
• Try using more partitions, you should have 2 - 4 per CPU. IME increasing the number of partitions is often the easiest way to make a program more stable (and often faster). For huge amounts of data you may need way more than 4 per CPU, I've had to use 8000 partitions in some cases!
• Decrease the fraction of memory reserved for caching, using spark.storage.memoryFraction. If you don't use cache() or persist in your code, this might as well be 0. It's default is 0.6, which means you only get 0.4 * 4g memory for your heap. IME reducing the mem frac often makes OOMs go away. UPDATE: From spark 1.6 apparently we will no longer need to play with these values, spark will determine them automatically.
• Similar to above but shuffle memory fraction. If your job doesn't need much shuffle memory then set it to a lower value (this might cause your shuffles to spill to disk which can have catastrophic impact on speed). Sometimes when it's a shuffle operation that's OOMing you need to do the opposite i.e. set it to something large, like 0.8, or make sure you allow your shuffles to spill to disk (it's the default since 1.0.0).
• Watch out for memory leaks, these are often caused by accidentally closing over objects you don't need in your lambdas. The way to diagnose is to look out for the "task serialized as XXX bytes" in the logs, if XXX is larger than a few k or more than an MB, you may have a memory leak. See https://stackoverflow.com/a/25270600/1586965
• Related to above; use broadcast variables if you really do need large objects.
• If you are caching large RDDs and can sacrifice some access time consider serialising the RDD http://spark.apache.org/docs/latest/tuning.html#serialized-rdd-storage. Or even caching them on disk (which sometimes isn't that bad if using SSDs).
• (Advanced) Related to above, avoid String and heavily nested structures (like Map and nested case classes). If possible try to only use primitive types and index all non-primitives especially if you expect a lot of duplicates. Choose WrappedArray over nested structures whenever possible. Or even roll out your own serialisation - YOU will have the most information regarding how to efficiently back your data into bytes, USE IT!
• (bit hacky) Again when caching, consider using a Dataset to cache your structure as it will use more efficient serialisation. This should be regarded as a hack when compared to the previous bullet point. Building your domain knowledge into your algo/serialisation can minimise memory/cache-space by 100x or 1000x, whereas all a Dataset will likely give is 2x - 5x in memory and 10x compressed (parquet) on disk.

EDIT: (So I can google myself easier) The following is also indicative of this problem:

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

Curl is a non-java program and must be provided outside your Java program.

You can easily get much of the functionality using Jakarta Commons Net, unless there is some specific functionality like "resume transfer" you need (which is tedious to code on your own)

You can also use this:

<fieldset>
<input type="radio" name="myoptions[]" value="blue"> Blue<br />
<input type="radio" name="myoptions[]" value="red"> Red<br />
<input type="radio" name="myoptions[]" value="green"> Green<br />
<label for="myoptions[]" class="error" style="display:none;">Please choose one.</label>
</fieldset>

and simply add this rule

rules: {
 'myoptions[]':{ required:true }
}

Mention how to add rules.

This works for me in IE 7, FF 3.5, Chrome 3b, Safari 4 (Windows).

Also works in IE 6 if you uncomment the clearer div at the bottom. Edit: as Natalie Downe said, you can simply add width: 100%; to #container instead.

I don't know a CSS way to vertically center the text in the right div if the div isn't of fixed height. If it is, you can set the line-height to the same value as the div height and put an inner div containing your text with display: inline; line-height: 110%.

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True

You can create an ImageButton in your android activity_main.xml and which image you want to place in your button just paste that image in your drawable folder below is the sample code for your reference.

<ImageButton
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginBottom="49dp"
    android:layout_weight="1"
    android:onClick="prev"
    android:src="@drawable/prev"
    />

Probably something like this? (UNTESTED)

Sub Sample()
    Dim strWB4, strMyMacro
    strMyMacro = "Sheet1.my_macro_name"

    '
    '~~> Rest of Code
    '

    'loop through the folder and get the file names
    For Each Fil In FLD.Files
        Set x4WB = x1.Workbooks.Open(Fil)
        x4WB.Application.Visible = True

        x1.Run strMyMacro

        x4WB.Close

        Do Until IsWorkBookOpen(Fil) = False
            DoEvents
        Loop
    Next

    '
    '~~> Rest of Code
    '
End Sub

'~~> Function to check if the file is open
Function IsWorkBookOpen(FileName As String)
    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0:    IsWorkBookOpen = False
    Case 70:   IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select

You can't mix in stored procedures with ordinary SQL, whilst with stored function you can.

e.g. SELECT get_foo(myColumn) FROM mytable is not valid if get_foo() is a procedure, but you can do that if get_foo() is a function. The price is that functions have more limitations than a procedure.

I was facing the same issue and solved with below code. (if any TLS connectivity issue)

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

Please paste this line before open the client channel.

If none of the above solution worked for you, locate the Wifi adapter from "Control Panel\Network and Internet\Network Connections", right click on it, and select "Diagnose", then follow the given instructions on the screen. It worked for me.

I used the following for creating a custom progress bar.

File res/drawable/progress_bar_states.xml declares the colors of the different states:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">
        <shape>
            <gradient
                    android:startColor="#000001"
                    android:centerColor="#0b131e"
                    android:centerY="0.75"
                    android:endColor="#0d1522"
                    android:angle="270"
            />
        </shape>
    </item>

    <item android:id="@android:id/secondaryProgress">
        <clip>
            <shape>
                <gradient
                        android:startColor="#234"
                        android:centerColor="#234"
                        android:centerY="0.75"
                        android:endColor="#a24"
                        android:angle="270"
                />
            </shape>
        </clip>
    </item>

    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <gradient
                    android:startColor="#144281"
                    android:centerColor="#0b1f3c"
                    android:centerY="0.75"
                    android:endColor="#06101d"
                    android:angle="270"
                />
            </shape>
        </clip>
    </item>

</layer-list>

And the code inside your layout xml:

<ProgressBar android:id="@+id/progressBar"
    android:progressDrawable="@drawable/progress_bar_states"
    android:layout_width="fill_parent" android:layout_height="8dip" 
    style="?android:attr/progressBarStyleHorizontal" 
    android:indeterminateOnly="false" 
    android:max="100">
</ProgressBar>

Enjoy!

The most efficient selector you can use is an attribute selector.

 input[name="btnPage"]:hover {/*your css here*/}

Here's a live demo: http://tinkerbin.com/3G6B93Cb

i believe this jquery work for you well please check a code below.

this will make your submit action works and open a link in new tab whether you want to open action url again or a new link

jQuery('form').on('submit',function(e){
setTimeout(function () { window.open('https://www.google.com','_blank');}, 1000);});})

This code works for me perfect..

All the metadata about the columns in Oracle Database is accessible using one of the following views.

user_tab_cols; -- For all tables owned by the user

all_tab_cols ; -- For all tables accessible to the user

dba_tab_cols; -- For all tables in the Database.

So, if you are looking for a column like ADD_TMS in SCOTT.EMP Table and add the column only if it does not exist, the PL/SQL Code would be along these lines..

DECLARE
  v_column_exists number := 0;  
BEGIN
  Select count(*) into v_column_exists
    from user_tab_cols
    where upper(column_name) = 'ADD_TMS'
      and upper(table_name) = 'EMP';
      --and owner = 'SCOTT --*might be required if you are using all/dba views

  if (v_column_exists = 0) then
      execute immediate 'alter table emp add (ADD_TMS date)';
  end if;
end;
/

If you are planning to run this as a script (not part of a procedure), the easiest way would be to include the alter command in the script and see the errors at the end of the script, assuming you have no Begin-End for the script..

If you have file1.sql

alter table t1 add col1 date;
alter table t1 add col2 date;
alter table t1 add col3 date;

And col2 is present,when the script is run, the other two columns would be added to the table and the log would show the error saying "col2" already exists, so you should be ok.

I personally do it this way, keeping the embedded CASE expressions confined. I'd also put comments in to explain what is going on. If it is too complex, break it out into function.

SELECT
    col1,
    col2,
    col3,
    CASE WHEN condition THEN
      CASE WHEN condition1 THEN
        CASE WHEN condition2 THEN calculation1
        ELSE calculation2 END
      ELSE
        CASE WHEN condition2 THEN calculation3
        ELSE calculation4 END
      END
    ELSE CASE WHEN condition1 THEN 
      CASE WHEN condition2 THEN calculation5
      ELSE calculation6 END
    ELSE CASE WHEN condition2 THEN calculation7
         ELSE calculation8 END
    END AS 'calculatedcol1',
    col4,
    col5 -- etc
FROM table

Try to use the following code. It will help you in full or more.

1. A .xml file designed to use this code to set background color:

   android:background="#000000"
   

   or

   android:background="#FFFFFF"
   

   

   Or you can set it programmatically as well.

2. Also you can use this code programmatically:

   image.setBackgroundDrawable(getResources().getDrawable(
       R.drawable.llabackground));
   

3. Also this code for setting the background color as well programmatically:

   image.setBackgroundColor(Color.parseColor("#FFFFFF"));
   

4. This code for the same programmatically:

   image.setBackgroundColor(getResources().getColor(Color.WHITE));
   

The color depends on your choice of which color you want to use for transparent. Mostly use a white or #FFFFFF color.

Regarding R.drawable.llabackground: This line of code is for your style of the background, like something special or different for your purpose. You can also use this.

DateTime dateTime = DateTime.Now ; 
string today = dateTime.DayOfWeek.ToString();
string yesterday = dateTime.AddDays(-1).DayOfWeek.ToString(); //Fetch day i.e. Mon, Tues
string result = dateTime.AddDays(-1).ToString("yyyy-MM-dd");

The above snippet will work. It is also advisable to make single instance of DateTime.Now;

Check out this implementation of PHP's strtotime() in JavaScript!

I found that it works identically to PHP for everything that I threw at it.

Update: this function as per version 1.0.2 can't handle this case: '2007:07:20 20:52:45' (Note the : separator for year and month)

Update 2018:

This is now available as an npm module! Simply npm install locutus and then in your source:

var strtotime = require('locutus/php/datetime/strtotime');

Display line numbers:

:set nu

Stop showing the line numbers:

:set nonu

Its short for :set nonumber

ps. These commands are to be run in normal mode.

Here is a code to split the data into n=5 folds in a stratified manner

% X = data array
% y = Class_label
from sklearn.cross_validation import StratifiedKFold
skf = StratifiedKFold(y, n_folds=5)
for train_index, test_index in skf:
    print("TRAIN:", train_index, "TEST:", test_index)
    X_train, X_test = X[train_index], X[test_index]
    y_train, y_test = y[train_index], y[test_index]

Open up terminal first and then go to directory of web server

cd /Library/WebServer/Documents

and then type this and what you will do is you will give read and write permission

sudo chmod -R o+w /Library/WebServer/Documents

This will surely work!

I just want to propose another alternative that will concern some of you :

android:configChanges="orientation|keyboardHidden" 

implies that we explicitly declare the layout to be injected.

In case we want to keep the automatic injection thanks to the layout-land and layout folders. All you have to do is add it to the onCreate:

    if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
        getSupportActionBar().hide();

    } else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
        getSupportActionBar().show();
    }

Here, we display or not the actionbar depending on the orientation of the phone

If your table has ordering by id, you could easily done by:

select * from table where id > 10

For me following was working:

var completionHandler:((Float)->Void)!

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

The title attribute works on most HTML tags and is widely supported by modern browsers.

You can use:

SELECT 1 FROM MyTable WHERE <MyCondition>

If there is no record matching the condition, the resulted recordset is empty.

I assume that you want them sorted by something else also, to get a consistent ordering between all items where AVC is the same. For example by name:

var sortedList = list.OrderBy(x => c.AVC).ThenBy(x => x.Name).ToList();

Since 2017 and Symfony 3.3 you can register Repository as service, with all its advantages it has.

Check my post How to use Repository with Doctrine as Service in Symfony for more general description.

To your specific case, original code with tuning would look like this:

1. Use in your services or Controller

<?php

namespace Test\CommonBundle\Services;

use Doctrine\ORM\EntityManagerInterface;

class UserService
{
    private $userRepository;

    // use custom repository over direct use of EntityManager
    // see step 2
    public function __constructor(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function getUser($userId)
    {
        return $this->userRepository->find($userId);
    }
}

2. Create new custom repository

<?php

namespace Test\CommonBundle\Repository;

use Doctrine\ORM\EntityManagerInterface;

class UserRepository
{
    private $repository;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->repository = $entityManager->getRepository(UserEntity::class);
    }

    public function find($userId)
    {
        return  $this->repository->find($userId);
    }
}

3. Register services

# app/config/services.yml
services:
    _defaults:
        autowire: true

    Test\CommonBundle\:
       resource: ../../Test/CommonBundle

These functions, based on the above, seem to work well for getting characters from the keyboard (blocking and non-blocking):

import termios, fcntl, sys, os

def get_char_keyboard():
  fd = sys.stdin.fileno()

  oldterm = termios.tcgetattr(fd)
  newattr = termios.tcgetattr(fd)
  newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
  termios.tcsetattr(fd, termios.TCSANOW, newattr)

  c = None
  try:
    c = sys.stdin.read(1)
  except IOError: pass

  termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)

  return c

def get_char_keyboard_nonblock():
  fd = sys.stdin.fileno()

  oldterm = termios.tcgetattr(fd)
  newattr = termios.tcgetattr(fd)
  newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
  termios.tcsetattr(fd, termios.TCSANOW, newattr)

  oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
  fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

  c = None

  try:
    c = sys.stdin.read(1)
  except IOError: pass

  termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
  fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

  return c

If you want list of error messages met in Sql server, you can see with

SELECT *

In my case

git rm -r .

The area of abcd`s PDF is not one, which is impossible like pointed out in many comments. Assumptions done in many answers here

1. Assume constant distance between consecutive edges.
2. Probability under pdf should be 1. The normalization should be done as Normalization with probability, not as Normalization with pdf, in histogram() and hist().

Fig. 1 Output of hist() approach, Fig. 2 Output of histogram() approach

The max amplitude differs between two approaches which proposes that there are some mistake in hist()'s approach because histogram()'s approach uses the standard normalization. I assume the mistake with hist()'s approach here is about the normalization as partially pdf, not completely as probability.

Code with hist() [deprecated]

Some remarks

1. First check: sum(f)/N gives 1 if Nbins manually set.
2. pdf requires the width of the bin (dx) in the graph g

Code

%http://stackoverflow.com/a/5321546/54964
N=10000;
Nbins=50;
[f,x]=hist(randn(N,1),Nbins); % create histogram from ND

%METHOD 4: Count Densities, not Sums!
figure(3)
dx=diff(x(1:2)); % width of bin
g=1/sqrt(2*pi)*exp(-0.5*x.^2) .* dx; % pdf of ND with dx
% 1.0000
bar(x, f/sum(f));hold on
plot(x,g,'r');hold off

Output is in Fig. 1.

Code with histogram()

Some remarks

1. First check: a) sum(f) is 1 if Nbins adjusted with histogram()'s Normalization as probability, b) sum(f)/N is 1 if Nbins is manually set without normalization.
2. pdf requires the width of the bin (dx) in the graph g

Code

%%METHOD 5: with histogram()
% http://stackoverflow.com/a/38809232/54964
N=10000;

figure(4);
h = histogram(randn(N,1), 'Normalization', 'probability') % hist() deprecated!
Nbins=h.NumBins;
edges=h.BinEdges; 
x=zeros(1,Nbins);
f=h.Values;
for counter=1:Nbins
    midPointShift=abs(edges(counter)-edges(counter+1))/2; % same constant for all
    x(counter)=edges(counter)+midPointShift;
end
dx=diff(x(1:2)); % constast for all
g=1/sqrt(2*pi)*exp(-0.5*x.^2) .* dx; % pdf of ND
% Use if Nbins manually set
%new_area=sum(f)/N % diff of consecutive edges constant
% Use if histogarm() Normalization probability
new_area=sum(f)
% 1.0000
% No bar() needed here with histogram() Normalization probability
hold on;
plot(x,g,'r');hold off

Output in Fig. 2 and expected output is met: area 1.0000.

You could use a cross-over ethernet cable - http://en.wikipedia.org/wiki/Ethernet_crossover_cable

Assuming your RPi is a DCHP Client, then best to run a simple DHCP server on your notebook to assign the RPi an IP address.

Try quoting the argument list:

Start-Process -FilePath "C:\Program Files\MSBuild\test.exe" -ArgumentList "/genmsi/f $MySourceDirectory\src\Deployment\Installations.xml"

You can also provide the argument list as an array (comma separated args) but using a string is usually easier.

use:

#ifdef __linux__ 
    //linux code goes here
#elif _WIN32
    // windows code goes here
#else

#endif

For funsies... just collect the extensions in a dict, and track all of them in a folder. Then just pull the extensions you want.

import os

search = {}

for f in os.listdir(os.getcwd()):
    fn, fe = os.path.splitext(f)
    try:
        search[fe].append(f)
    except:
        search[fe]=[f,]

extensions = ('.png','.jpg')
for ex in extensions:
    found = search.get(ex,'')
    if found:
        print(found)

In the lastest version of code with express-generator (4.13.1) app.js is an exported module and the server is started in /bin/www using app.set('port', process.env.PORT || 3001) in app.js will be overridden by a similar statement in bin/www. I just changed the statement in bin/www.

Unfortunately, what you want is not possible with Python (which makes Python close to useless for command-line one-liner programs). Even explicit use of parentheses does not avoid the syntax exception. You can get away with a sequence of simple statements, separated by semi-colon:

for i in range(10): print "foo"; print "bar"

But as soon as you add a construct that introduces an indented block (like if), you need the line break. Also,

for i in range(10): print "i equals 9" if i==9 else None

is legal and might approximate what you want.

As for the try ... except thing: It would be totally useless without the except. try says "I want to run this code, but it might throw an exception". If you don't care about the exception, leave away the try. But as soon as you put it in, you're saying "I want to handle a potential exception". The pass then says you wish to not handle it specifically. But that means your code will continue running, which it wouldn't otherwise.

Yes, require is a Node.JS function and doesn't work in client side scripting without certain requirements. If you're getting this error while writing electronJS code, try the following:

In your BrowserWindow declaration, add the following webPreferences field: i.e, instead of plain mainWindow = new BrowserWindow(), write

mainWindow = new BrowserWindow({
        webPreferences: {
            nodeIntegration: true
        }
    });

Try this:

Use back-ticks for NAME

CREATE TABLE `teachers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `addr` varchar(255) NOT NULL,
  `phone` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

Use Date convert to compare with date: Try This:

select * from table 
where TO_DATE(to_char(timespanColumn,'YYYY-MM-DD'),'YYYY-MM-DD') = to_timestamp('2018-03-26', 'YYYY-MM-DD')

for macOS, ?+N by default.

@ruchira ur solution it self is best.But i think if it is only about integer and a string we can do it in much easy and simple way..

 class B {   
    public String myfun() {         
        int a=2;           //Integer .. you could use scanner or pass parameters ..i have simply assigned
        String b="hi";      //String
        return Integer.toString(a)+","+b; //returnig string and int with "," in middle          
    }       
}

class A {    
    public static void main(String args[]){

        B obj=new B();  // obj of class B with myfun() method  
        String returned[]=obj.myfun().split(",");
             //splitting integer and string values with "," and storing them in array   
        int b1=Integer.parseInt(returned[0]); //converting first value in array to integer.    
        System.out.println(returned[0]); //printing integer    
        System.out.println(returned[1]); //printing String
    }
}

i hope it was useful.. :)

Ensure compiled dll of your project placed in proper bin folder.

In my case, when i have changed the compiled directory of our subproject to bin folder of our main project, it worked.

use jquery event filter

you can use it like this

$("a:Event(click)")

You can use Decode as well:

SELECT DISTINCT a.item, decode(b.salesman,'VIKKIE','ICKY',Else),NVL(a.manufacturer,'Not Set')Manufacturer
FROM inv_items a, arv_sales b
WHERE a.co = b.co
      AND A.ITEM_KEY = b.item_key
      AND a.co = '100'
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
                         and to_date('011713','mmddrr')
GROUP BY a.item, b.salesman, a.manufacturer
ORDER BY a.item

        int large = 0, second = 0;

        for (int i = 0; i < input.length - 1; i = i + 2) {
            // System.out.println(i);
            int fist = input[i];
            int sec = input[i + 1];
            if (sec >= fist) {
                int temp = fist;
                fist = sec;
                sec = temp;
            }
            if (fist >= second) {
                if (fist >= large) {
                    large = fist;
                } else {
                    second = fist;

                if (sec >= large) {
                    large = sec;
                } else {
                    second = sec;
                }
            }
        }
    }
}

Try Calender. Use getInstance to get a Calender-Object. Then use setTime to set the required Date. Now you can use get(int field) with the appropriate constant like HOUR_OF_DAY or so to read the values you need.

In EF Core you no longer can execute "free" raw sql. You are required to define a POCO class and a DbSet for that class. In your case you will need to define Rank:

var ranks = DbContext.Ranks
   .FromSql("SQL_SCRIPT OR STORED_PROCEDURE @p0,@p1,...etc", parameters)
   .AsNoTracking().ToList();

As it will be surely readonly it will be useful to include the .AsNoTracking() call.

EDIT - Breaking change in EF Core 3.0:

DbQuery() is now obsolete, instead DbSet() should be used (again). If you have a keyless entity, i.e. it don't require primary key, you can use HasNoKey() method:

ModelBuilder.Entity<SomeModel>().HasNoKey()

You can try:

 function onlyAlphabets(e, t) {
        return (e.charCode > 64 && e.charCode < 91) || (e.charCode > 96 && e.charCode < 123) || e.charCode == 32;   
    }

For React.js, the following is what worked for me in the footer...

render() {
    const yearNow = new Date().getFullYear();
    return (
    <div className="copyright">&copy; Company 2015-{yearNow}</div>
);
}

Try to use this xPath expression:

//book/title[@lang='it']/..

That should give you all book nodes in "it" lang

I do not think the above answer is "wrong" but there are large areas of authentication that are not touched upon (or rather the emphasis is on "how to implement cookie sessions", not on "what options are available and what are the trade-offs".

My suggested edits/answers are

• The problem lies more in account setup than in password checking.
• The use of two-factor authentication is much more secure than more clever means of password encryption

• Do NOT try to implement your own login form or database storage of passwords, unless the data being stored is valueless at account creation and self-generated (that is, web 2.0 style like Facebook, Flickr, etc.)

  1. Digest Authentication is a standards-based approach supported in all major browsers and servers, that will not send a password even over a secure channel.

This avoids any need to have "sessions" or cookies as the browser itself will re-encrypt the communication each time. It is the most "lightweight" development approach.

However, I do not recommend this, except for public, low-value services. This is an issue with some of the other answers above - do not try an re-implement server-side authentication mechanisms - this problem has been solved and is supported by most major browsers. Do not use cookies. Do not store anything in your own hand-rolled database. Just ask, per request, if the request is authenticated. Everything else should be supported by configuration and third-party trusted software.

So ...

First, we are confusing the initial creation of an account (with a password) with the re-checking of the password subsequently. If I am Flickr and creating your site for the first time, the new user has access to zero value (blank web space). I truly do not care if the person creating the account is lying about their name. If I am creating an account of the hospital intranet/extranet, the value lies in all the medical records, and so I do care about the identity (*) of the account creator.

This is the very very hard part. The only decent solution is a web of trust. For example, you join the hospital as a doctor. You create a web page hosted somewhere with your photo, your passport number, and a public key, and hash them all with the private key. You then visit the hospital and the system administrator looks at your passport, sees if the photo matches you, and then hashes the web page/photo hash with the hospital private key. From now on we can securely exchange keys and tokens. As can anyone who trusts the hospital (there is the secret sauce BTW). The system administrator can also give you an RSA dongle or other two-factor authentication.

But this is a lot of a hassle, and not very web 2.0. However, it is the only secure way to create new accounts that have access to valuable information that is not self-created.

1. Kerberos and SPNEGO - single sign-on mechanisms with a trusted third party - basically the user verifies against a trusted third party. (NB this is not in any way the not to be trusted OAuth)

2. SRP - sort of clever password authentication without a trusted third party. But here we are getting into the realms of "it's safer to use two-factor authentication, even if that's costlier"

3. SSL client side - give the clients a public key certificate (support in all major browsers - but raises questions over client machine security).

In the end, it's a tradeoff - what is the cost of a security breach vs the cost of implementing more secure approaches. One day, we may see a proper PKI widely accepted and so no more own rolled authentication forms and databases. One day...

As you're using Python 3, there is no urllib module anymore. It has been split into several modules.

This would be equivalent to urlretrieve:

import urllib.request
data = urllib.request.urlretrieve("http://...")

urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.

Basically:

• urlretrieve saves the file to a temporary file and returns a tuple (filename, headers)
• urlopen returns a Request object whose read method returns a bytestring containing the file contents

You can use org.apache.commons.lang.time.DateUtils to make it cleaner:

(firstDate.getTime() - secondDate.getTime()) / DateUtils.MILLIS_PER_SECOND

On my machine mysqld service stopped that's why it was giving me the same problem.

1:- Go to terminal and type

sudo service mysqld restart

This will restart the mysqld service and create a new sock file on the required location.

PEP-8 is the official python coding standard. It contains a section on docstrings, which refers to PEP-257 -- a complete specification for docstrings.

This might help

var link = document.createElementNS("http://www.w3.org/1999/xhtml", "a");

This will works to show your window in full screen

Note: For this to work, you need Query from http://code.jquery.com/jquery-2.1.1.min.js

Or make have javascript link like this.

<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

   <div id="demo-element">

            element.mozRequestFullScreen();
        else if(element.webkitRequestFullscreen)
            element.webkitRequestFullscreen();

            document.webkitExitFullscreen();
        else if(document.msExitFullscreen)
            document.msExitFullscreen();
    }

    function IsFullScreenCurrently() {
        var full_screen_element = document.fullscreenElement || document.webkitFullscreenElement || document.mozFullScreenElement || document.msFullscreenElement || null;

        if(full_screen_element === null)
            return false;

            return true;
    }

    $("#go-button").on('click', function() {
        if(IsFullScreenCurrently())
            GoOutFullscreen();
        else
            GoInFullscreen($("#demo-element").get(0));
    });

    $(document).on('fullscreenchange webkitfullscreenchange mozfullscreenchange MSFullscreenChange', function() {
        if(IsFullScreenCurrently()) {
            $("#demo-element span").text('Full Screen Mode Enabled');
            $("#go-button").text('Disable Full Screen');
        }
        else {
            $("#demo-element span").text('Full Screen Mode Disabled');
            $("#go-button").text('Enable Full Screen');
        }
    });</script>

It can be done using Java's sleep method. I've tested it in FF and IE and it doesn't lock the computer, chew up resources, or cause endless server hits. Seems like a clean solution to me.

First you have to get Java loaded up on the page and make its methods available. To do that, I did this:

<html>
<head>

<script type="text/javascript">

  function load() {
    var appletRef = document.getElementById("app");
    window.java = appletRef.Packages.java;
  } // endfunction

</script>

<body onLoad="load()">

<embed id="app" code="java.applet.Applet" type="application/x-java-applet" MAYSCRIPT="true" width="0" height="0" />

Then, all you have to do when you want a painless pause in your JS is:

java.lang.Thread.sleep(xxx)

Where xxx is time in milliseconds. In my case (by way of justification), this was part of back-end order fulfillment at a very small company and I needed to print an invoice that had to be loaded from the server. I did it by loading the invoice (as a webpage) into an iFrame and then printing the iFrame. Of course, I had to wait until the page was fully loaded before I could print, so the JS had to pause. I accomplished this by having the invoice page (in the iFrame) change a hidden form field on the parent page with the onLoad event. And the code on the parent page to print the invoice looked like this (irrelevant parts cut for clarity):

var isReady = eval('document.batchForm.ready');
isReady.value=0;

frames['rpc_frame'].location.href=url;

while (isReady.value==0) {
  java.lang.Thread.sleep(250);
} // endwhile

window.frames['rpc_frame'].focus();
window.frames['rpc_frame'].print();

So the user pushes the button, the script loads the invoice page, then waits, checking every quarter second to see if the invoice page is finished loading, then pops up the print dialog for the user to send it to the printer. QED.

you can get it in your controller:

using System.Security.Claims;
var userId = this.User.FindFirstValue(ClaimTypes.NameIdentifier);

or write an extension method like before .Core v1.0

using System;
using System.Security.Claims;

namespace Shared.Web.MvcExtensions
{
    public static class ClaimsPrincipalExtensions
    {
        public static string GetUserId(this ClaimsPrincipal principal)
        {
            if (principal == null)
                throw new ArgumentNullException(nameof(principal));

            return principal.FindFirst(ClaimTypes.NameIdentifier)?.Value;
        }
    }
}

and get wherever user ClaimsPrincipal is available :

using Microsoft.AspNetCore.Mvc;
using Shared.Web.MvcExtensions;

namespace Web.Site.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return Content(this.User.GetUserId());
        }
    }
}

Apply the reverse function to the range to iterate backwards:

For Swift 1.2 and earlier:

// Print 10 through 1
for i in reverse(1...10) {
    println(i)
}

It also works with half-open ranges:

// Print 9 through 1
for i in reverse(1..<10) {
    println(i)
}

Note: reverse(1...10) creates an array of type [Int], so while this might be fine for small ranges, it would be wise to use lazy as shown below or consider the accepted stride answer if your range is large.

To avoid creating a large array, use lazy along with reverse(). The following test runs efficiently in a Playground showing it is not creating an array with one trillion Ints!

Test:

var count = 0
for i in lazy(1...1_000_000_000_000).reverse() {
    if ++count > 5 {
        break
    }
    println(i)
}

For Swift 2.0 in Xcode 7:

for i in (1...10).reverse() {
    print(i)
}

Note that in Swift 2.0, (1...1_000_000_000_000).reverse() is of type ReverseRandomAccessCollection<(Range<Int>)>, so this works fine:

var count = 0
for i in (1...1_000_000_000_000).reverse() {
    count += 1
    if count > 5 {
        break
    }
    print(i)
}

For Swift 3.0 reverse() has been renamed to reversed():

for i in (1...10).reversed() {
    print(i) // prints 10 through 1
}

The simpler and current approach for adding header to a single request is:

// Step 1

const yourHeader: HttpHeaders = new HttpHeaders({
    Authorization: 'Bearer JWT-token'

// POST request

this.http.post(url, body, { headers: yourHeader });

// GET request

this.http.get(url, { headers: yourHeader });

You don't need a derived table at all for this.

Just put the INTO after the first SELECT

SELECT top(100)* 
INTO tmpFerdeen
FROM Customers
UNION All
SELECT top(100)* 
FROM CustomerEurope
UNION All
SELECT top(100)* 
FROM CustomerAsia
UNION All
SELECT top(100)* 
FROM CustomerAmericas

I have adopted your script for my situation Jotne.

#! /bin/bash

logfile="/var/oscamlog/oscam1check.log"

case "$(pidof oscam1 | wc -w)" in

0)  echo "oscam1 not running, restarting oscam1:     $(date)" >> $logfile
    /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1 &
    ;;
2)  echo "oscam1 running, all OK:     $(date)" >> $logfile
    ;;
*)  echo "multiple instances of oscam1 running. Stopping & restarting oscam1:     $(date)" >> $logfile
    kill $(pidof oscam1 | awk '{print $1}')
    ;;
esac

While I was testing, I ran into a problem.. I started 3 extra process's of oscam1 with this line: /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1 which left me with 8 process for oscam1. the problem is this.. When I run the script, It only kills 2 process's at a time, so I would have to run it 3 times to get it down to 2 process..

Other than killall -9 oscam1 followed by /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1, in *)is there any better way to killall apart from the original process? So there would be zero downtime?

Try __FILE__ and __LINE__.
You might also find __DATE__ and __TIME__ useful.
Though unless you have to debug a program on the clientside and thus need to log these informations you should use normal debugging.

Yes. You can use *args as a non-keyword argument. You will then be able to pass any number of arguments.

def manyArgs(*arg):
  print "I was called with", len(arg), "arguments:", arg

>>> manyArgs(1)
I was called with 1 arguments: (1,)
>>> manyArgs(1, 2, 3)
I was called with 3 arguments: (1, 2, 3)

As you can see, Python will unpack the arguments as a single tuple with all the arguments.

For keyword arguments you need to accept those as a separate actual argument, as shown in Skurmedel's answer.

To answer your first question: yes it is feasible to develop an android application in pure python, in order to achieve this I suggest you use BeeWare, which is just a suite of python tools, that work together very well and they enable you to develop platform native applications in python.

checkout this video by the creator of BeeWare that perfectly explains and demonstrates it's application

How it works

Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine. This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java .class file, which can be packaged into an Android application.

VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes. Using this, you can write an Android application directly against the native Android APIs.

Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application.

Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:

• Mac
• Windows
• Linux
• iPhone/iPad
• Android
• AppleTV
• tvOS.

You can check This native Android Tic Tac Toe app written in Python, using the BeeWare suite. on GitHub

in addition to the BeeWare tools, you'll need to have a JDK and Android SDK installed to test run your application.

and to answer your second question: a good environment can be anything you are comfortable with be it a text editor and a command line, or an IDE, if you're looking for a good python IDE I would suggest you try Pycharm, it has a community edition which is free, and it has a similar environment as android studio, due to to the fact that were made by the same company.

I hope this has been helpful

NOTE The question in the bounty by @WilliamJockusch and the original question are different.

This answer is about StackOverflow's in the general case of third-party libraries and what you can/can't do with them. If you're looking about the special case with XslTransform, see the accepted answer.

Stack overflows happen because the data on the stack exceeds a certain limit (in bytes). The details of how this detection works can be found here.

I'm wondering if there is a general way to track down StackOverflowExceptions. In other words, suppose I have infinite recursion somewhere in my code, but I have no idea where. I want to track it down by some means that is easier than stepping through code all over the place until I see it happening. I don't care how hackish it is.

As I mentioned in the link, detecting a stack overflow from static code analysis would require solving the halting problem which is undecidable. Now that we've established that there is no silver bullet, I can show you a few tricks that I think helps track down the problem.

I think this question can be interpreted in different ways, and since I'm a bit bored :-), I'll break it down into different variations.

Detecting a stack overflow in a test environment

Basically the problem here is that you have a (limited) test environment and want to detect a stack overflow in an (expanded) production environment.

Instead of detecting the SO itself, I solve this by exploiting the fact that the stack depth can be set. The debugger will give you all the information you need. Most languages allow you to specify the stack size or the max recursion depth.

Basically I try to force a SO by making the stack depth as small as possible. If it doesn't overflow, I can always make it bigger (=in this case: safer) for the production environment. The moment you get a stack overflow, you can manually decide if it's a 'valid' one or not.

To do this, pass the stack size (in our case: a small value) to a Thread parameter, and see what happens. The default stack size in .NET is 1 MB, we're going to use a way smaller value:

class StackOverflowDetector
{
    static int Recur()
    {
        int variable = 1;
        return variable + Recur();
    }

    static void Start()
    {
        int depth = 1 + Recur();
    }

    static void Main(string[] args)
    {
        Thread t = new Thread(Start, 1);
        t.Start();
        t.Join();
        Console.WriteLine();
        Console.ReadLine();
    }
}

Note: we're going to use this code below as well.

Once it overflows, you can set it to a bigger value until you get a SO that makes sense.

Creating exceptions before you SO

The StackOverflowException is not catchable. This means there's not much you can do when it has happened. So, if you believe something is bound to go wrong in your code, you can make your own exception in some cases. The only thing you need for this is the current stack depth; there's no need for a counter, you can use the real values from .NET:

class StackOverflowDetector
{
    static void CheckStackDepth()
    {
        if (new StackTrace().FrameCount > 10) // some arbitrary limit
        {
            throw new StackOverflowException("Bad thread.");
        }
    }

    static int Recur()
    {
        CheckStackDepth();
        int variable = 1;
        return variable + Recur();
    }

    static void Main(string[] args)
    {
        try
        {
            int depth = 1 + Recur();
        }
        catch (ThreadAbortException e)
        {
            Console.WriteLine("We've been a {0}", e.ExceptionState);
        }
        Console.WriteLine();
        Console.ReadLine();
    }
}

Note that this approach also works if you are dealing with third-party components that use a callback mechanism. The only thing required is that you can intercept some calls in the stack trace.

Detection in a separate thread

You explicitly suggested this, so here goes this one.

You can try detecting a SO in a separate thread.. but it probably won't do you any good. A stack overflow can happen fast, even before you get a context switch. This means that this mechanism isn't reliable at all... I wouldn't recommend actually using it. It was fun to build though, so here's the code :-)

class StackOverflowDetector
{
    static int Recur()
    {
        Thread.Sleep(1); // simulate that we're actually doing something :-)
        int variable = 1;
        return variable + Recur();
    }

    static void Start()
    {
        try
        {
            int depth = 1 + Recur();
        }
        catch (ThreadAbortException e)
        {
            Console.WriteLine("We've been a {0}", e.ExceptionState);
        }
    }

    static void Main(string[] args)
    {
        // Prepare the execution thread
        Thread t = new Thread(Start);
        t.Priority = ThreadPriority.Lowest;

        // Create the watch thread
        Thread watcher = new Thread(Watcher);
        watcher.Priority = ThreadPriority.Highest;
        watcher.Start(t);

        // Start the execution thread
        t.Start();
        t.Join();

        watcher.Abort();
        Console.WriteLine();
        Console.ReadLine();
    }

    private static void Watcher(object o)
    {
        Thread towatch = (Thread)o;

        while (true)
        {
            if (towatch.ThreadState == System.Threading.ThreadState.Running)
            {
                towatch.Suspend();
                var frames = new System.Diagnostics.StackTrace(towatch, false);
                if (frames.FrameCount > 20)
                {
                    towatch.Resume();
                    towatch.Abort("Bad bad thread!");
                }
                else
                {
                    towatch.Resume();
                }
            }
        }
    }
}

Run this in the debugger and have fun of what happens.

Using the characteristics of a stack overflow

Another interpretation of your question is: "Where are the pieces of code that could potentially cause a stack overflow exception?". Obviously the answer of this is: all code with recursion. For each piece of code, you can then do some manual analysis.

It's also possible to determine this using static code analysis. What you need to do for that is to decompile all methods and figure out if they contain an infinite recursion. Here's some code that does that for you:

// A simple decompiler that extracts all method tokens (that is: call, callvirt, newobj in IL)
internal class Decompiler
{
    private Decompiler() { }

    static Decompiler()
    {
        singleByteOpcodes = new OpCode[0x100];
        multiByteOpcodes = new OpCode[0x100];
        FieldInfo[] infoArray1 = typeof(OpCodes).GetFields();
        for (int num1 = 0; num1 < infoArray1.Length; num1++)
        {
            FieldInfo info1 = infoArray1[num1];
            if (info1.FieldType == typeof(OpCode))
            {
                OpCode code1 = (OpCode)info1.GetValue(null);
                ushort num2 = (ushort)code1.Value;
                if (num2 < 0x100)
                {
                    singleByteOpcodes[(int)num2] = code1;
                }
                else
                {
                    if ((num2 & 0xff00) != 0xfe00)
                    {
                        throw new Exception("Invalid opcode: " + num2.ToString());
                    }
                    multiByteOpcodes[num2 & 0xff] = code1;
                }
            }
        }
    }

    private static OpCode[] singleByteOpcodes;
    private static OpCode[] multiByteOpcodes;

    public static MethodBase[] Decompile(MethodBase mi, byte[] ildata)
    {
        HashSet<MethodBase> result = new HashSet<MethodBase>();

        Module module = mi.Module;

        int position = 0;
        while (position < ildata.Length)
        {
            OpCode code = OpCodes.Nop;

            ushort b = ildata[position++];
            if (b != 0xfe)
            {
                code = singleByteOpcodes[b];
            }
            else
            {
                b = ildata[position++];
                code = multiByteOpcodes[b];
                b |= (ushort)(0xfe00);
            }

            switch (code.OperandType)
            {
                case OperandType.InlineNone:

class StackOverflowDetector
{
    // This method will be found:
    static int Recur()

        CheckStackDepth();
        int variable = 1;
        return variable + Recur();
    }

    static void Main(string[] args)
    {
        RecursionDetector();
        Console.WriteLine();
        Console.ReadLine();
    }

    static void RecursionDetector()
    {
        // First decompile all methods in the assembly:
        Dictionary<MethodBase, MethodBase[]> calling = new Dictionary<MethodBase, MethodBase[]>();
        var assembly = typeof(StackOverflowDetector).Assembly;

        foreach (var type in assembly.GetTypes())
        {
            foreach (var member in type.GetMembers(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance).OfType<MethodBase>())
            {
                var body = member.GetMethodBody();
                if (body!=null)
                {
                    var bytes = body.GetILAsByteArray();
                    if (bytes != null)
                    {
                        // Store all the calls of this method:
                        var calls = Decompiler.Decompile(member, bytes);
                        calling[member] = calls;
                    }
                }
            }
        }

        // Check every method:
        foreach (var method in calling.Keys)
        {
            // If method A -> ... -> method A, we have a possible infinite recursion
            CheckRecursion(method, calling, new HashSet<MethodBase>());
        }
    }

Now, the fact that a method cycle contains recursion, is by no means a guarantee that a stack overflow will happen - it's just the most likely precondition for your stack overflow exception. In short, this means that this code will determine the pieces of code where a stack overflow can occur, which should narrow down most code considerably.

Yet other approaches

There are some other approaches you can try that I haven't described here.

1. Handling the stack overflow by hosting the CLR process and handling it. Note that you still cannot 'catch' it.
2. Changing all IL code, building another DLL, adding checks on recursion. Yes, that's quite possible (I've implemented it in the past :-); it's just difficult and involves a lot of code to get it right.
3. Use the .NET profiling API to capture all method calls and use that to figure out stack overflows. For example, you can implement checks that if you encounter the same method X times in your call tree, you give a signal. There's a project here that will give you a head start.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

ax[0, 0].plot(range(10), 'r') #row=0, col=0
ax[1, 0].plot(range(10), 'b') #row=1, col=0
ax[0, 1].plot(range(10), 'g') #row=0, col=1
ax[1, 1].plot(range(10), 'k') #row=1, col=1
plt.show()

Basically you need to download the IEDriverServer.exe from Selenium HQ website without executing anything just remmeber the location where you want it and then put the code on Eclipse like this

System.setProperty("webdriver.ie.driver", "C:\\Users\\juan.torres\\Desktop\\QA stuff\\IEDriverServer_Win32_2.32.3\\IEDriverServer.exe");
WebDriver driver= new InternetExplorerDriver();

driver.navigate().to("http://www.youtube.com/");

for the path use double slash //

ok have fun !!

I have used a syntax like this before:

$(ProjectDir)..\headers

or

..\headers

As other have pointed out, the starting directory is the one your project file is in(vcproj or vcxproj), not where your main code is located.

   $("[id$=btneNoteBulkExcelUpload]").hide();
   } 

     foreach (DataRow row in dt.Rows) 
     {
        foreach (DataColumn col in dt.Columns)
           Console.WriteLine(row[col]);
     }

Not in VB.NET, you have to select all lines at then Edit, Advanced, Comment Selection menu, or a keyboard shortcut for that menu.

Solution

Angular2 developed on the ground of modern technologies like TypeScript and ES6.

So you can just do let copy = Object.assign({}, myObject).

Object assign - nice examples.

For nested objects : let copy = JSON.parse(JSON.stringify(myObject))

And if you have this problem in slider or slideshow you must use jquery.easing.1.3:

<script src="http://gsgd.co.uk/sandbox/jquery/easing/jquery.easing.1.3.js"></script>

This might be a bit faster:

dir /A:-D /B *.* 2>nul | find /c /v ""

`/A:-D` - filters out only non directory items (files)
`/B`    - prints only file names (no need a full path request)
`*.*`   - can filters out specific file names (currently - all)
`2>nul` - suppresses all error lines output to does not count them

After struggling with this issue for quite some time I managed to solve it by allowing incoming connections on port 8080.

Since you wrote that the .listen(8080, "0.0.0.0") solution didn't work for you, make sure the connections on port 8080 are allowed through your firewall.

This post helped me to create a new Inbound rule in windows firewall settings.

If your file my.cnf (usually in the /etc/mysql/ folder) is correctly configured with

socket=/var/lib/mysql/mysql.sock

you can check if mysql is running with the following command:

mysqladmin -u root -p status

try changing your permission to mysql folder. If you are working locally, you can try:

sudo chmod -R 755 /var/lib/mysql/

that solved it for me

For me, works this way: mvn -f /path/to/pom.xml [goals]

You could try:

$rows = array();
while($row = mysql_fetch_array($result)){
  array_push($rows, $row);
}
echo json_encode($rows);

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

Just use this extension to move any UIView when keyboard is presented.

extension UIView {
    func bindToKeyboard(){
        NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillChange(_:)), name: NSNotification.Name.UIKeyboardWillChangeFrame, object: nil)
    }

    @objc func keyboardWillChange(_ notification: NSNotification){
        let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
        let curve = notification.userInfo![UIKeyboardAnimationCurveUserInfoKey] as! UInt
        let beginningFrame = (notification.userInfo![UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
        let endFrame = (notification.userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue

        let deltaY = endFrame.origin.y - beginningFrame.origin.y

        UIView.animateKeyframes(withDuration: duration, delay: 0.0, options: UIViewKeyframeAnimationOptions(rawValue: curve), animations: {
            self.frame.origin.y += deltaY
        }, completion: nil)
    }
}

Then in your viewdidload bind your view to the keyboard

UiView.bindToKeyboard()

Would you want the same form with different parts, showing each part accordingly with a button?

Here an example with three steps, that is, three form parts, but it is expandable to any number of form parts. The HTML characters « and » just print respectively « and » which might be interesting for the previous and next button characters.

_x000D_
/* this function shows form part [n] and hides the remaining form parts */_x000D_

  var i = 1, p = document.getElementById("form_part"+1);_x000D_

I experienced the same problem as the OP after right-clicking on my project and selecting Close Unrelated Projects.

In my case, I resolved the problem by re-opening the appcompat_v7 project and cleaning/rebuilding both projects.

I know this is an old post but I've just signed up for Azure and I get 25,000 emails a month for free via SendGrid. These instructions are excellent, I was up and running in minutes:

How to Send Email Using SendGrid with Azure

Azure customers can unlock 25,000 free emails each month.

Jinja 2.6 does not have the map function. So an alternate way of doing this would be:

set_fact: foo="{% for i in bar_result.results %}{{ i.ansible_facts.foo_item }}{%endfor%}"
