fwrite($handle, "<br>"."\r\n");

Add this under

$password = $_POST['password'].PHP_EOL;

this. .

Or you can add this method to your object:

    public void Save(string filename)
    {
        var ser = new XmlSerializer(this.GetType());
        using (var stream = new FileStream(filename, FileMode.Create))
            ser.Serialize(stream, this);
    }

You need to login to your mysql terminal first using mysql -u username -p password

Then use this:

SELECT @@sql_mode; or SELECT @@GLOBAL.sql_mode;

output will be like this:

STRICT_TRANS_TABLES,STRICT_ALL_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,TRADITIONAL,NO_AUTO_CREATE_USER,NO_ENGINE_SUB

You can also set sql mode by this:

SET GLOBAL sql_mode=TRADITIONAL;

I got a similar error with '/' operand while processing images. I discovered the folder included a text file created by the 'XnView' image viewer. So, this kind of error occurs when some object is not the kind of object expected.

If you need to fetch an object's property dynamically, use the getattr() function: getattr(user, "fullName") - or to elaborate:

user = User()
property = "fullName"
name = getattr(user, property)

Otherwise just use user.fullName.

Every example here shows a solution using the FileReader. It is convenient if you do not need to care about a file encoding. If you use some other languages than english, encoding is quite important. Imagine you have file with this text

Príliš žlutoucký kun
úpel dábelské ódy

and the file uses windows-1250 format. If you use FileReader you will get this result:

P??li? ?lu?ou?k? k??
?p?l ??belsk? ?dy

So in this case you would need to specify encoding as Cp1250 (Windows Eastern European) but the FileReader doesn't allow you to do so. In this case you should use InputStreamReader on a FileInputStream.

Example:

String encoding = "Cp1250";
File file = new File("foo.txt");

if (file.exists()) {
    try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), encoding))) {
        String line = null;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}
else {
    System.out.println("file doesn't exist");
}

In case you want to read the file character after character do not use BufferedReader.

try (InputStreamReader isr = new InputStreamReader(new FileInputStream(file), encoding)) {
    int data = isr.read();
    while (data != -1) {
        System.out.print((char) data);
        data = isr.read();
    }
} catch (IOException e) {
    e.printStackTrace();
}

This has worked for me:

let webApiUrl = 'example.com/getStuff';
let tokenStr = 'xxyyzz';
axios.get(webApiUrl, { headers: {"Authorization" : `Bearer ${tokenStr}`} });

There's now an easy way to do this using dplyr.

dplyr::pull(aframe, a2)

I came here looking for a simple 1-liner to remove/correct the identation level of the docstring for printing, without making it look untidy, for example by making it "hang outside the function" within the script.

Here's what I ended up doing:

import string
def myfunction():

    """
    line 1 of docstring
    line 2 of docstring
    line 3 of docstring"""

print str(string.replace(myfunction.__doc__,'\n\t','\n'))[1:] 

Obviously, if you're indenting with spaces (e.g. 4) rather than the tab key use something like this instead:

print str(string.replace(myfunction.__doc__,'\n    ','\n'))[1:]

And you don't need to remove the first character if you like your docstrings to look like this instead:

    """line 1 of docstring
    line 2 of docstring
    line 3 of docstring"""

print string.replace(myfunction.__doc__,'\n\t','\n') 

It is easy if you are using django version 3.1 and above

def login_view(request):
    if(request.POST):
        yourForm= YourForm(request.POST)
        itemValue = yourForm['your_filed_name'].value()
        # Check if you get the value
        return HttpResponse(itemValue )
    else:
        return render(request, "base.html")

Here is another way of converting a xml to pandas data frame. For example i have parsing xml from a string but this logic holds good from reading file as well.

import pandas as pd
import xml.etree.ElementTree as ET

xml_str = '<?xml version="1.0" encoding="utf-8"?>\n<response>\n <head>\n  <code>\n   200\n  </code>\n </head>\n <body>\n  <data id="0" name="All Categories" t="2018052600" tg="1" type="category"/>\n  <data id="13" name="RealEstate.com.au [H]" t="2018052600" tg="1" type="publication"/>\n </body>\n</response>'

etree = ET.fromstring(xml_str)
dfcols = ['id', 'name']
df = pd.DataFrame(columns=dfcols)

for i in etree.iter(tag='data'):
    df = df.append(
        pd.Series([i.get('id'), i.get('name')], index=dfcols),
        ignore_index=True)

df.head()

Try this:

pointer-events:none

Adding above on the specified HTML element will prevents all click, state and cursor options.

        });

In your supplementary question you asked if www.example.com/file[/].html is a valid URL.

That URL isn't valid because a URL is a type of URI and a valid URI must have a scheme like http: (see RFC 3986).

If you meant to ask if http://www.example.com/file[/].html is a valid URL then the answer is still no because the square bracket characters aren't valid there.

The square bracket characters are reserved for URLs in this format: http://[2001:db8:85a3::8a2e:370:7334]/foo/bar (i.e. an IPv6 literal instead of a host name)

It's worth reading RFC 3986 carefully if you want to understand the issue fully.

Here's my solution for Bootstrap 4:

<button id="search" class="btn btn-primary" 
data-loading-text="<i class='fa fa-spinner fa-spin fa-fw' aria-hidden='true'></i>Searching">
  Search
</button>

var setLoading = function () {
  var search = $('#search');
  if (!search.data('normal-text')) {
    search.data('normal-text', search.html());
  }
  search.html(search.data('loading-text'));
};

var clearLoading = function () {
  var search = $('#search');
  search.html(search.data('normal-text'));
};

setInterval(() => {
  setLoading();
  setTimeout(() => {
    clearLoading();
  }, 1000);
}, 2000);

No, there is nothing like this in CSS. You can, however, use JavaScript to calculate the number of children and apply styles.

This is are other ways of printing empty lines in python

# using \n after the string creates an empty line after this string is passed to the the terminal.
print("We need to put about", average_passengers_per_car, "in each car. \n") 
print("\n") #prints 2 empty lines 
print() #prints 1 empty line 

.row {
    margin-right: 15px;
}

throw this in your CSS

After adding this line of code, the issue will be fixed:

In the database, there are two options:

• bytea. Stores the data in a column, exported as part of a backup. Uses standard database functions to save and retrieve. Recommended for your needs.
• blobs. Stores the data externally, not normally exported as part of a backup. Requires special database functions to save and retrieve.

I've used bytea columns with great success in the past storing 10+gb of images with thousands of rows. PG's TOAST functionality pretty much negates any advantage that blobs have. You'll need to include metadata columns in either case for filename, content-type, dimensions, etc.

If you were talking about WPF then use:

 Application.Current.Windows.OfType<Window>().SingleOrDefault(w => w.IsActive);

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

The advantages of CXF:

1. CXF supports for WS-Addressing, WS-Policy, WS-RM, WS-Security and WS-I BasicProfile.
2. CXF implements JAX-WS API (according by JAX-WS 2.0 TCK).
3. CXF has better integration with Spring and other frameworks.
4. CXF has high extensibility in terms of their interceptor strategy.
5. CXF has more configurable feature via the API instead of cumbersome XML files.
6. CXF has Bindings:SOAP,REST/HTTP, and its Data Bindings support JAXB 2.0,Aegis, by default it use JAXB 2.0 and more close Java standard specification.
7. CXF has abundant toolkits, e.g. Java to WSDL, WSDL to Java, XSD to WSDL, WSDL to XML, WSDL to SOAP, WSDL to Service.

The advantages of Axis2:

1. Axis2 also supports WS-RM, WS-Security, and WS-I BasicProfile except for WS-Policy, I expect it will be supported in an upcoming version.
2. Axis has more options for data bindings for your choose
3. Axis2 supports multiple languages—including C/C++ version and Java version.
4. Axis2 supports a wider range of data bindings, including XMLBeans, JiBX, JaxMe and JaxBRI as well as its own native data binding, ADB. longer history than CXF.

In Summary: From above advantage items, it brings us to a good thoughts to compare Axis2 and CXF on their own merits. they all have different well-developed areas in a certain field, CXF is very configurable, integratable and has rich tool kits supported and close to Java community, Axis2 has taken an approach that makes it in many ways resemble an application server in miniature. it is across multiple programming languages. because its Independence, Axis2 lends itself towards web services that stand alone, independent of other applications, and offers a wide variety of functionality.

As a developer, we need to accord our perspective to choose the right one, whichever framework you choose, you’ll have the benefit of an active and stable open source community. In terms of performance, I did a test based the same functionality and configed in the same web container, the result shows that CXF performed little bit better than Axis2, the single case may not exactly reflect their capabilities and performance.

In some research articles, it reveals that Axis2's proprietary ADB databinding is a bit faster than CXF since it don’t have additional feature(WS-Security). Apache AXIS2 is relatively most used framework but Apache CXF scores over other Web Services Framework comparatively considering ease of development, current industry trend, performance, overall scorecard and other features (unless there is Web Services Orchestration support is explicitly needed, which is not required here)

Just to add - Safari 2 and earlier definitely didn't support PUT and DELETE. I get the impression 3 did, but I don't have it around to test anymore. Safari 4 definitely does support PUT and DELETE.

It's best to do this with numpy in my opinion

import numpy as np
import pandas as pd
d = pd.DataFrame(np.zeros((N_rows, N_cols)))

Your syntax is fine, it will return rows where LastAdDate lies within the last 6 months;

select cast('01-jan-1970' as datetime) as LastAdDate into #PubAdvTransData 
    union select GETDATE()
    union select NULL
    union select '01-feb-2010'

DECLARE @sp_Date DATETIME = DateAdd(m, -6, GETDATE())

SELECT * FROM #PubAdvTransData pat
     WHERE (pat.LastAdDate > @sp_Date)

>2010-02-01 00:00:00.000
>2010-04-29 21:12:29.920

Are you sure LastAdDate is of type DATETIME?

Another way in which this could be achieved is

df['color'] = df.Set.map( lambda x: 'red' if x == 'Z' else 'green')

You can make it like that:

    <html>
<head>
    <style>
        .round {
            display:block;
            width: 55px;
            height: 55px;
            border-radius: 50%;
            overflow: hidden;
            padding:5px 4px;
        }
        .round img {
            width: 45px;
        }
    </style>
</head>
<body>
    <div class="round">
        <img src="image.jpg" />
    </div>
</body>

Treat IllegalArgumentException as a preconditions check, and consider the design principle: A public method should both know and publicly document its own preconditions.

I would agree this example is correct:

void setPercentage(int pct) {
    if( pct < 0 || pct > 100) {
         throw new IllegalArgumentException("bad percent");
     }
}

If EmailUtil is opaque, meaning there's some reason the preconditions cannot be described to the end-user, then a checked exception is correct. The second version, corrected for this design:

import com.someoneelse.EmailUtil;

public void scanEmail(String emailStr, InputStream mime) throws ParseException {
    EmailAddress parsedAddress = EmailUtil.parseAddress(emailStr);
}

If EmailUtil is transparent, for instance maybe it's a private method owned by the class under question, IllegalArgumentException is correct if and only if its preconditions can be described in the function documentation. This is a correct version as well:

/** @param String email An email with an address in the form [email protected]
 * with no nested comments, periods or other nonsense.
 */
public String scanEmail(String email)
  if (!addressIsProperlyFormatted(email)) {
      throw new IllegalArgumentException("invalid address");
  }
  return parseEmail(emailAddr);
}
private String parseEmail(String emailS) {
  // Assumes email is valid
  boolean parsesJustFine = true;
  // Parse logic
  if (!parsesJustFine) {
    // As a private method it is an internal error if address is improperly
    // formatted. This is an internal error to the class implementation.
    throw new AssertError("Internal error");
  }
}

This design could go either way.

• If preconditions are expensive to describe, or if the class is intended to be used by clients who don't know whether their emails are valid, then use ParseException. The top level method here is named scanEmail which hints the end user intends to send unstudied email through so this is likely correct.
• If preconditions can be described in function documentation, and the class does not intent for invalid input and therefore programmer error is indicated, use IllegalArgumentException. Although not "checked" the "check" moves to the Javadoc documenting the function, which the client is expected to adhere to. IllegalArgumentException where the client can't tell their argument is illegal beforehand is wrong.

A note on IllegalStateException: This means "this object's internal state (private instance variables) is not able to perform this action." The end user cannot see private state so loosely speaking it takes precedence over IllegalArgumentException in the case where the client call has no way to know the object's state is inconsistent. I don't have a good explanation when it's preferred over checked exceptions, although things like initializing twice, or losing a database connection that isn't recovered, are examples.

As lots of others have said, you will need to use multiple ALTER COLUMN statements, one for each column you want to modify.

If you want to modify all or several of the columns in your table to the same datatype (such as expanding a VARCHAR field from 50 to 100 chars), you can generate all the statements automatically using the query below. This technique is also useful if you want to replace the same character in multiple fields (such as removing \t from all columns).

SELECT
     TABLE_CATALOG
    ,TABLE_SCHEMA
    ,TABLE_NAME
    ,COLUMN_NAME
    ,'ALTER TABLE ['+TABLE_SCHEMA+'].['+TABLE_NAME+'] ALTER COLUMN ['+COLUMN_NAME+'] VARCHAR(300)' as 'code'
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'your_table' AND TABLE_SCHEMA = 'your_schema'

This generates an ALTER TABLE statement for each column for you.

In the POSIX standard, which /bin/sh is supposed to respect, the command is . (a single dot), not source. The source command is a csh-ism that has been pulled into bash.

Try

. $env_name/bin/activate

Or if you must have non-POSIX bash-isms in your code, use #!/bin/bash.

There are several things wrong with this as you can see in the other posts, but the reason you're getting that error is because you name your form getElementById. So document.getElementById now points to your form instead of the default method that javascript provides. See my fiddle for a working demo https://jsfiddle.net/jemartin80/nhjehwqk/.

function checkValues()
{
   var isFormValid, form_fname;

   isFormValid = true;
   form_fname = document.getElementById("fname");
   if (form_fname.value === "")
   {
       isFormValid = false;
   }
   isFormValid || alert("I am indicating that there is something wrong with your input.")

   return isFormValid;
}

You can add a simple css3 rule in the body or in specific div, use pointer-events: none; property.

You can try this...

Use the TextFieldParser class built into the .Net framework.

Here's some code copied from an MSDN forum post by Paul Clement. It converts the CSV into a new in-memory DataTable and then binds the DataGridView to the DataTable

    Dim TextFileReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("C:\Documents and Settings\...\My Documents\My Database\Text\SemiColonDelimited.txt")

    TextFileReader.TextFieldType = FileIO.FieldType.Delimited
    TextFileReader.SetDelimiters(";")

    Dim TextFileTable As DataTable = Nothing

    Dim Column As DataColumn
    Dim Row As DataRow
    Dim UpperBound As Int32
    Dim ColumnCount As Int32
    Dim CurrentRow As String()

    While Not TextFileReader.EndOfData
        Try
            CurrentRow = TextFileReader.ReadFields()
            If Not CurrentRow Is Nothing Then
                ''# Check if DataTable has been created
                If TextFileTable Is Nothing Then
                    TextFileTable = New DataTable("TextFileTable")
                    ''# Get number of columns
                    UpperBound = CurrentRow.GetUpperBound(0)
                    ''# Create new DataTable
                    For ColumnCount = 0 To UpperBound
                        Column = New DataColumn()
                        Column.DataType = System.Type.GetType("System.String")
                        Column.ColumnName = "Column" & ColumnCount
                        Column.Caption = "Column" & ColumnCount
                        Column.ReadOnly = True
                        Column.Unique = False
                        TextFileTable.Columns.Add(Column)
                    Next
                End If
                Row = TextFileTable.NewRow
                For ColumnCount = 0 To UpperBound
                    Row("Column" & ColumnCount) = CurrentRow(ColumnCount).ToString
                Next

Under Tools > Preferences > Databases there is a third party JDBC driver path that must be setup. Once the driver path is setup a separate 'MySQL' tab should appear on the New Connections dialog.

Note: This is the same jdbc connector that is available as a JAR download from the MySQL website.

After establising the connection and executing the query try this:

 ResultSet resultSet;
 int columnCount = resultSet.getMetaData().getColumnCount();
 System.out.println("column count : "+columnCount);

I don't know if anyone is still following this thread, but I recently had this issue when I tried to launch ActiveMQ 5.10 as a Windows service.

I didn't have a JAVA_HOME path set. I had Java 6 and Java 7 installed, but the default version was v7. (ie if I opened a command window and types "java -version").

This is where the clue was - "java -version" returned "Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)" but I was had installed the Win32 service...

It turns out that if you use the Win32 wrapper on a 64-bit machine it somehow decides to use a different version of Java...

So my fix was to uninstall the 32-bit version of the wrapper and install the 64-bit version. aversion on my machine; just habit I guess... But luckily I resolved the issue eventually...

You also can set the width of a audio tag by JavaScript:

audio = document.getElementById('audio-id');
audio.style.width = '200px';

You might need to change your path by:

import os
path=os.chdir(str('Here should be the path to your file')) #This command changes directory

This is what worked for me at least! Hope it works for you too!

A connection timeout is the maximum amount of time that the program is willing to wait to setup a connection to another process. You aren't getting or posting any application data at this point, just establishing the connection, itself.

A socket timeout is the timeout when waiting for individual packets. It's a common misconception that a socket timeout is the timeout to receive the full response. So if you have a socket timeout of 1 second, and a response comprised of 3 IP packets, where each response packet takes 0.9 seconds to arrive, for a total response time of 2.7 seconds, then there will be no timeout.

Try using this code:

var event = new Date();
var options = { weekday: 'long' };
console.log(event.toLocaleDateString('en-US', options));

this will give you the day name in string format.

Yes, since some genius in the Java API creation committee decided that, even though certain classes have size() members or length attributes, they won't implement getSize() or getLength() which JSF and most other standards require, you can't do what you want.

There's a couple ways to do this.

One: add a function to your Bean that returns the length:

In class MyBean:
public int getSomelistLength() { return this.somelist.length; }

In your JSF page:
#{MyBean.somelistLength}

Two: If you're using Facelets (Oh, God, why aren't you using Facelets!), you can add the fn namespace and use the length function

In JSF page:
#{ fn:length(MyBean.somelist) }

Follow this step it will convert string to number

$value = '$0025.123';
$onlyNumeric = filter_var($value, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
settype($onlyNumeric,"float");

$result=($onlyNumeric+100);
echo $result;

Another way to do it :

$res = preg_replace("/[^0-9.]/", "", "$15645623.095605659");

There are multiple options available for generating HTML reports for Selenium WebDriver scripts.

1. Use the JUNIT TestWatcher class for creating your own Selenium HTML reports

The TestWatcher JUNIT class allows overriding the failed() and succeeded() JUNIT methods that are called automatically when JUNIT tests fail or pass.

The TestWatcher JUNIT class allows overriding the following methods:

• protected void failed(Throwable e, Description description)

failed() method is invoked when a test fails

• protected void finished(Description description)

finished() method is invoked when a test method finishes (whether passing or failing)

• protected void skipped(AssumptionViolatedException e, Description description)

skipped() method is invoked when a test is skipped due to a failed assumption.

• protected void starting(Description description)

starting() method is invoked when a test is about to start

• protected void succeeded(Description description)

succeeded() method is invoked when a test succeeds

See below sample code for this case:

import static org.junit.Assert.assertTrue;
import org.junit.Test;

public class TestClass2 extends WatchManClassConsole {

    @Test public void testScript1() {
        assertTrue(1 < 2); >
    }

    @Test public void testScript2() {
        assertTrue(1 > 2);
    }

    @Test public void testScript3() {
        assertTrue(1 < 2);
    }

    @Test public void testScript4() {
        assertTrue(1 > 2);
    }
}

import org.junit.Rule; 
import org.junit.rules.TestRule; 
import org.junit.rules.TestWatcher; 
import org.junit.runner.Description; 
import org.junit.runners.model.Statement; 

public class WatchManClassConsole {

    @Rule public TestRule watchman = new TestWatcher() { 

        @Override public Statement apply(Statement base, Description description) { 
            return super.apply(base, description); 
        } 

        @Override protected void succeeded(Description description) { 
            System.out.println(description.getDisplayName() + " " + "success!"); 
        } 

        @Override protected void failed(Throwable e, Description description) { 
            System.out.println(description.getDisplayName() + " " + e.getClass().getSimpleName()); 
        }
    }; 
}

2. Use the Allure Reporting framework

Allure framework can help with generating HTML reports for your Selenium WebDriver projects.

The reporting framework is very flexible and it works with many programming languages and unit testing frameworks.

You can read everything about it at http://allure.qatools.ru/.

You will need the following dependencies and plugins to be added to your pom.xml file

1. maven surefire
2. aspectjweaver
3. allure adapter

The correct answer is, you need to set JUST body to overflow:hidden. For whatever reason, if you also set html to overflow:hidden the result is the problem you've described.

SELECT (cast(timestamp_1 as bigint) - cast(timestamp_2 as bigint)) FROM table;

In case if someone is having an issue using extract.

You shouldn't be using onClick any more if you are using jQuery. jQuery provides its own methods of attaching and binding events. See .click()

$(document).ready(function(){
    var js = "alert('B:' + this.id); return false;";
    // create a function from the "js" string
    var newclick = new Function(js);

    // clears onclick then sets click using jQuery
    $("#anchor").attr('onclick', '').click(newclick);
});

That should cancel the onClick function - and keep your "javascript from a string" as well.

The best thing to do would be to remove the onclick="" from the <a> element in the HTML code and switch to using the Unobtrusive method of binding an event to click.

You also said:

Using onclick = function() { return eval(js); } doesn't work because you are not allowed to use return in code passed to eval().

No - it won't, but onclick = eval("(function(){"+js+"})"); will wrap the 'js' variable in a function enclosure. onclick = new Function(js); works as well and is a little cleaner to read. (note the capital F) -- see documentation on Function() constructors

(Assuming Excel 2003...)

When using the Text-to-Columns Wizard has, in Step 3 you can dictate the data type for each of the columns. Click on the column in the preview and change the misbehaving column from "General" to "Text."

I suspect its a new feature since this post was created - pass parameters to the script block using $Using:var. Then its a simple mater to pass parameters provided the script is already on the machine or in a known network location relative to the machine

Taking the main example it would be:

icm -cn $Env:ComputerName { 
    C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 -one "uno" -two "dos" -Debug -Clear $Using:Clear
}

HTML CODE:

<table class="table table-hover">
    <thead>
        <tr>
            <th>Firstname</th>
            <th>Lastname</th>
            <th>Email</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>John</td>
            <td>Doe</td>
            <td>[email protected]</td>
        </tr>
        <tr>
            <td>Mary</td>
            <td>Moe</td>
            <td>[email protected]</td>
        </tr>
        <tr>
            <td>July</td>
            <td>Dooley</td>
            <td>[email protected]</td>
        </tr>
    </tbody>

CSS CODE

.table-hover thead tr:hover th, .table-hover tbody tr:hover td {
    background-color: #D1D119;
}

The css code indicate that:

mouse over row:

.table-hover > thead > tr:hover

background color of th will change to #D1D119

th

Same action will happen for tbody

.table-hover tbody tr:hover td

I don't believe AJAX can handle file uploads but this can be achieved with libraries that leverage flash. Another advantage of the flash implementation is the ability to do multiple files at once (like gmail).

SWFUpload is a good start : http://www.swfupload.org/documentation

jQuery and some of the other libraries have plugins that leverage SWFUpload. On my last project we used SWFUpload and Java without a problem.

Also helpful and worth looking into is Apache's FileUpload : http://commons.apache.org/fileupload/index.html

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.

To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data to an array before not after you try to slice it:

R = np.array(mean_data)[:,0]

instead of

R = np.array(mean_data[:,0])

But, assuming mean_data has a shape nx3, instead of

R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]

You can simply do

A = np.array(mean_data).mean(axis=0)

which averages over the 0th axis and returns a length-n array

But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:

PHP 5.4 has a function called http_response_code, so if you're using PHP 5.4 you can just do:

http_response_code(500);

I've written a polyfill for this function (Gist) if you're running a version of PHP under 5.4.

To answer your follow-up question, the HTTP 1.1 RFC says:

The reason phrases listed here are only recommendations -- they MAY be replaced by local equivalents without affecting the protocol.

That means you can use whatever text you want (excluding carriage returns or line feeds) after the code itself, and it'll work. Generally, though, there's usually a better response code to use. For example, instead of using a 500 for no record found, you could send a 404 (not found), and for something like "conditions failed" (I'm guessing a validation error), you could send something like a 422 (unprocessable entity).

InnoDB supports RENAME TABLE statement to move table from one database to another. To use it programmatically and rename database with large number of tables, I wrote a couple of procedures to get the job done. You can check it out here - SQL script @Gist

To use it simply call the renameDatabase procedure.

CALL renameDatabase('old_name', 'new_name');

Tested on MariaDB and should work ideally on all RDBMS using InnoDB transactional engine.

$('#loginBtn').click(function(e) {
    e.preventDefault(); /// it should not have this code or else it wont continue
    //....
});

Run Below Commands in Line:-

1. stop-all.sh (Run Stop All to Stop all the hadoop process)
2. rm -r /usr/local/hadoop/tmp/ (Your Hadoop tmp directory which you configured in hadoop/conf/core-site.xml)
3. sudo mkdir /usr/local/hadoop/tmp (Make the same directory again)
4. hadoop namenode -format (Format your namenode)
5. start-all.sh (Run Start All to start all the hadoop process)
6. JPS (It will show the running processes)

I think in your Angular-2 version directives are not supported in Component decorator, hence you have to register directive same as other component in @NgModule and then import in component as below and also remove directives: [ChildComponent] from decorator.

import {myDirective} from './myDirective';

process.stdin.pipe(process.stdout);

EDIT : It is not bleeding edge anymore : http://blog.docker.com/2016/02/docker-1-10/

Original Answer
I battled with it the whole night. If you're not afraid of bleeding edge, the latest version of Docker engine and Docker compose both implement libnetwork.

With the right config file (that need to be put in version 2), you will create services that will all see each other. And, bonus, you can scale them with docker-compose as well (you can scale any service you want that doesn't bind port on the host)

Here is an example file

version: "2"
services:
  router:
    build: services/router/
    ports:
      - "8080:8080"
  auth:
    build: services/auth/
  todo:
    build: services/todo/
  data:
    build: services/data/

And the reference for this new version of compose file: https://github.com/docker/compose/blob/1.6.0-rc1/docs/networking.md

Simply call this method to get the Firebase Messaging Token

public void getFirebaseMessagingToken ( ) {
        FirebaseMessaging.getInstance ().getToken ()
                .addOnCompleteListener ( task -> {
                    if (!task.isSuccessful ()) {
                        //Could not get FirebaseMessagingToken
                        return;
                    }
                    if (null != task.getResult ()) {
                        //Got FirebaseMessagingToken
                        String firebaseMessagingToken = Objects.requireNonNull ( task.getResult () );
                        //Use firebaseMessagingToken further
                    }
                } );
    }

The above code works well after adding this dependency in build.gradle file

implementation 'com.google.firebase:firebase-messaging:21.0.0'

Note: This is the code modification done for the above dependency to resolve deprecation. (Working code as of 1st November 2020)

as suggested, you can use 'die and dump' such as

dd($var)

or only 'dump', without dying,

dump($var)

You could create a CSS class for this and apply it to your columns. Since the gutter (spacing between columns) is controlled by padding in Bootstrap 3, adjust the padding accordingly:

.col {
  padding-right:7px;
  padding-left:7px;
}

Demo: http://bootply.com/93473

EDIT If you only want the spacing between columns you can select all cols except first and last like this..

.col:not(:first-child,:last-child) {
  padding-right:7px;
  padding-left:7px;
}

Updated Bootply

For Bootstrap 4 see: Remove gutter space for a specific div only

There are several methods of std::string for searching, but find is probably what you're looking for. If you mean a C-style string, then the equivalent is strchr. However, in either case, you can also use a for loop and check each character—the loop is essentially what these two wrap up.

Once you know how to find the next character given a starting position, you continually advance your search (i.e. use a loop), counting as you go.

\\d{3} matches any sequence of three digits in Java.

You should use PDO Prepare

From the link:

Calling PDO::prepare() and PDOStatement::execute() for statements that will be issued multiple times with different parameter values optimizes the performance of your application by allowing the driver to negotiate client and/or server side caching of the query plan and meta information, and helps to prevent SQL injection attacks by eliminating the need to manually quote the parameters.

The below code worked.

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Add this code before calling videoView.start(). With this the video activity runs in full screen mode in most of the cases. But if the title bar is still displayed then change your theme in your manifest to this.

    android:theme="@style/Theme.AppCompat.NoActionBar">

You can use list slicing to archive your goal:

n = 5
mylist = [1,2,3,4,5,6,7,8,9]
newlist = mylist[n:]
print newlist

Outputs:

[6, 7, 8, 9]

Or del if you only want to use one list:

n = 5
mylist = [1,2,3,4,5,6,7,8,9]
del mylist[:n]
print mylist

Outputs:

[6, 7, 8, 9]

Just window.location = "http://wherever.you.wanna.go.com/", or, for local links, window.location = "my_relative_link.html".

You can try it by typing it into your address bar as well, e.g. javascript: window.location = "http://www.google.com/".

Also note that the protocol part of the URL (http://) is not optional for absolute links; omitting it will make javascript assume a relative link.

First, Single throws an exception if there is more than one element satisfying the criteria. Second, your criteria should only check if the Correct property is true. Right now, you are checking if a is equal to a.Correct (which will not even compile).

You should use First (which will throw if there are no such elements), or FirstOrDefault (which will return null for a reference type if there isn't such element):

// this will return the first correct answer,
// or throw an exception if there are no correct answers
var correct = answers.First(a => a.Correct); 

// this will return the first correct answer, 
// or null if there are no correct answers
var correct = answers.FirstOrDefault(a => a.Correct); 

// this will return a list containing all answers which are correct,
// or an empty list if there are no correct answers
var allCorrect = answers.Where(a => a.Correct).ToList();

image

Variable-length binary data from 0 through 2^31-1 (2,147,483,647) bytes. Still it IS supported to use image datatype, but be aware of:

https://docs.microsoft.com/en-us/sql/t-sql/data-types/binary-and-varbinary-transact-sql

varbinary [ ( n | max) ]

Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length. The ANSI SQL synonym for varbinary is binary varying.

So both are equally in size (2GB). But be aware of:

https://docs.microsoft.com/en-us/sql/database-engine/deprecated-database-engine-features-in-sql-server-2016#features-not-supported-in-a-future-version-of-sql-server

Though the end of "image" datatype is still not determined, you should use the "future" proof equivalent.

But you have to ask yourself: why storing BLOBS in a Column?

Make a new class SortedObservableCollection, derive it from ObservableCollection and implement IComparable<Pair<ushort, string>>.

This may help a small percentage of people still scratching their heads. Text copied from clipboard into VSCode may have an invisible hard space character preventing wrapping. Check it with HTML inspector

Try something like this:

#include <signal.h>

    child_pid = fork();
    if (child_pid > 0) {
     /*PARENT*/
        alarm(30);
        /*

From a controller you can also return an Object/Array and it will be sent as a JSON response (including the correct HTTP headers).

public function show($id)
{
    return Customer::find($id);
}

$('#cf_1268591').attr("disabled", true); 

drop down is always read only . what you can do is make it disabled

if you work with a form , the disabled fields does not submit , so use a hidden field to store disabled dropdown value

The following syntax fixes it for you:

curl -v -F key1=value1 -F upload=@localfilename URL

You should bind the tap event, the click does not exist on mobile safari or in the UIWbview. You can also use this polyfill ,to avoid the 300ms delay when a link is touched.

just take a new class beside every row and apply css of margin-top: 20px;
here is the code below
<style>
  .small-top
   {
     margin-top: 25px;  
   }
</style>    
<div class="row small-top">
   <div class="col-md-12">

You maybe not asking the UWP api. But in UWP, file.DisplayName is the name without extensions. Hope useful for others.

Method below also works.

$users = User::all()->map(function ($user) {
  return collect($user)->only(['id', 'name', 'email']);
});

What I have found best is a CSRF token and save it in the session for links where you need to verify the referrer.

So if you are generating a FB callback then it would look something like this:

$token = uniqid(mt_rand(), TRUE);
$_SESSION['token'] = $token;
$url = "http://example.com/index.php?token={$token}";

Then the index.php will look like this:

if(empty($_GET['token']) || $_GET['token'] !== $_SESSION['token'])
{
    show_404();
} 

//Continue with the rest of code

I do know of secure sites that do the equivalent of this for all their secure pages.

I'm trying to make a "bubble" that can popup when the onmouseover event is fired and will stay open as long as the mouse is over the item that threw the onmouseover event OR if the mouse is moved into the bubble. My bubble will need to have all manners of html and styling including hyperlinks, images, etc.

All those events fully managed by this plugin...

I came across a solution based on a few answers popped in the thread. (windows 10)

setwd("D:/path to folder where the files are")
directory <- getwd()
myfile<- "a_file_in_the_folder.txt"
filepath=paste0(directory,"/",myfile[1],sep="")
table <- read.table(table, sep = "\t", header=T, row.names = 1, dec=",")

Here is a website that will give you what you need

As a summary, it provides links to InputMethodManager and View from Android Developers. It will reference to the getWindowToken inside of View and hideSoftInputFromWindow() for InputMethodManager

A better answer is given in the link, hope this helps.

here is an example to consume the onTouch event:

editText_input_field.setOnTouchListener(otl);

private OnTouchListener otl = new OnTouchListener() {
  public boolean onTouch (View v, MotionEvent event) {
        return true; // the listener has consumed the event
  }
};

Here is another example from the same website. This claims to work but seems like a bad idea since your EditBox is NULL it will be no longer an editor:

MyEditor.setOnTouchListener(new OnTouchListener(){

  @Override
  public boolean onTouch(View v, MotionEvent event) {
    int inType = MyEditor.getInputType(); // backup the input type
    MyEditor.setInputType(InputType.TYPE_NULL); // disable soft input
    MyEditor.onTouchEvent(event); // call native handler
    MyEditor.setInputType(inType); // restore input type
    return true; // consume touch even
  }
});

Hope this points you in the right direction

I solved this by simple copy and paste method. I don't know it is the best way to do this but,for me it works good and almost instantaneously. Here is my code.

    private void copyAlltoClipboard()
    {
        dataGridView1.SelectAll();
        DataObject dataObj = dataGridView1.GetClipboardContent();
        if (dataObj != null)
            Clipboard.SetDataObject(dataObj);
    }
    private void button3_Click_1(object sender, EventArgs e)
    {
        copyAlltoClipboard();
        Microsoft.Office.Interop.Excel.Application xlexcel;
        Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
        Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;
        xlexcel = new Excel.Application();
        xlexcel.Visible = true;
        xlWorkBook = xlexcel.Workbooks.Add(misValue);
        xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        Excel.Range CR = (Excel.Range)xlWorkSheet.Cells[1, 1];
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);          
    }

Thanks.

You can also use window.setInterval() to run some code repeatedly at a regular interval.

WPF contains the following MessageBox:

if (MessageBox.Show("Do you want to Save?", "Confirm", 
    MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes)
{

}

The given answer is far from complete. In fact, it is so far from complete that it tends to lead the reader to believe that this answer is OS dependent when it isn't. It also isn't something which is programming language dependent (as some commentators have suggested). I'm going to add more information in order to make this more clear. First, lets give the list of current new line variations (as in, what they've been since 1999):

• \r\n is only used on Windows Notepad, the DOS command line, most of the Windows API and in some (older) Windows apps.
• \n is used for all other systems, applications and the Internet.

You'll notice that I've put most Windows apps in the \n group which may be slightly controversial but before you disagree with this statement, please grab a UNIX formatted text file and try it in 10 web friendly Windows applications of your choice (which aren't listed in my exceptions above). What percentage of them handled it just fine? You'll find that they (practically) all implement auto detection of line endings or just use \n because, while Windows may use \r\n, the Internet uses \n. Therefore, it is best practice for applications to use \n alone if you want your output to be Internet friendly.

PHP also defines a newline character called PHP_EOL. This constant is set to the OS specific newline string for the machine PHP is running on (\r\n for Windows and \n for everything else). This constant is not very useful for webpages and should be avoided for HTML output or for writing most text to files. It becomes VERY useful when we move to command line output from PHP applications because it will allow your application to output to a terminal Window in a consistent manner across all supported OSes.

If you want your PHP applications to work from any server they are placed on, the two biggest things to remember are that you should always just use \n unless it is terminal output (in which case you use PHP_EOL) and you should also ALWAYS use / for your path separator (not \).

The even longer explanation:

An application may choose to use whatever line endings it likes regardless of the default OS line ending style. If I want my text editor to print a newline every time it encounters a period that is no harder than using the \n to represent a newline because I'm interpreting the text as I display it anyway. IOW, I'm fiddling around with measuring the width of each character so it knows where to display the next so it is very simple to add a statement saying that if the current char is a period then perform a newline action (or if it is a \n then display a period).

Aside from the null terminator, no character code is sacred and when you write a text editor or viewer you are in charge of translating the bits in your file into glyphs (or carriage returns) on the screen. The only thing that distinguishes a control character such as the newline from other characters is that most font sets don't include them (meaning they don't have a visual representation available).

That being said, if you are working at a higher level of abstraction then you probably aren't making your own textbox controls. If this is the case then you're stuck with whatever line ending that control makes available to you. Even in this case it is a simple matter to automatically detect the line ending style of any string and make the conversion before you load your text into the control and then undo it when you read from that control. Meaning, that if you're a desktop application dev and your application doesn't recognize \n as a newline then it isn't a very friendly application and you really have no excuse because it isn't hard to make it the right way. It also means that whomever wrote Notepad should be ashamed of himself because it really is very easy to do much better and so many people suffer through using it every day.

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." />

Replace it by:

<context:component-scan base-package="org.assessme.com." />

It is because your Autowired service is not scanned by Spring since it is not in the right package.

You need to put the arguments to pass ("/select etc") in the second parameter of the Start method.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

SELECT count(word) as count 
FROM words 
GROUP BY word
HAVING count >= 2;

check your tab order and make sure the textbox is set to zero

The answer is given in @dku-rajkumar post.

ArrayList commonList = CollectionUtils.retainAll(list1,list2);

Wow, an amazing number of people misread the question. It's easy to make a cell look empty. The problem is that if you need the cell to be empty, Excel formulas can't return "no value" but can only return a value. Returning a zero, a space, or even "" is a value.

So you have to return a "magic value" and then replace it with no value using search and replace, or using a VBA script. While you could use a space or "", my advice would be to use an obvious value, such as "NODATE" or "NONUMBER" or "XXXXX" so that you can easily see where it occurs - it's pretty hard to find "" in a spreadsheet.

One thing to be aware of, is that isVisible() returns the visible state of the current fragment. There is a problem in the support library, where if you have nested fragments, and you hide the parent fragment (and therefore all the children), the child still says it is visible.

isVisible() is final, so can't override unfortunately. My workaround was to create a BaseFragment class that all my fragments extend, and then create a method like so:

public boolean getIsVisible()
{
    if (getParentFragment() != null && getParentFragment() instanceof BaseFragment)
    {
        return isVisible() && ((BaseFragment) getParentFragment()).getIsVisible();
    }
    else
    {
        return isVisible();
    }
}

I do isVisible() && ((BaseFragment) getParentFragment()).getIsVisible(); because we want to return false if any of the parent fragments are hidden.

This seems to do the trick for me.

AFAIS, nobody mentions of final usage for that. If you modify your last example and define variables a and b as final variables, then the compiler is assured that their sum, value 5 , can be assigned to a variable of type byte, without any loss of precision. In this case, the compiler is good to assign the sum of a and b to c . Here’s the modified code:

final byte a = 2;
final byte b = 3;
byte c = a + b;

Use compareTo:

date1.compareTo(date2);

From the Maven docs, sounds like it's just a difference in which repository you install the package into:

• install - install the package into the local repository, for use as a dependency in other projects locally
• deploy - done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

Maybe there is some confusion in that "install" to the CI server installs it to it's local repository, which then you as a user are sharing?

As the comments to the question say, you will need pandoc and latex (e.g. TeXShop). I installed pandoc with Homebrew, it took just a second. Having pandoc and TeXShop, I could generate latex but not pdf (on the command line).

ipython nbconvert --to latex mynotebook.ipynb

Exploring the latex (.tex) file with TeXShop, the failure was due to missing stylesheets and defs. After installing all of these (adjustbox.sty, adjcalc.sty, trimclip.sty, collectbox.sty, tc-pgf.def, ucs.sty, uni-global.def, utf8x.def, ucsencs.def), it did finally work.

However, the result looks a little too funky for my taste. It is too bad that printing the html from Safari loses the syntax coloring. Otherwise, it doesn't look so bad. (This is all on OS X).

This is a prompt to create a bunch of object, such as sp_help_diagram (?), that do not exist.

This should have nothing to do with the owner of the db.

You need to use the proper git URL:

pip install git+https://github.com/jkbr/httpie.git#egg=httpie

Also see the VCS Support section of the pip documentation.

Don’t forget to include the egg=<projectname> part to explicitly name the project; this way pip can track metadata for it without having to have run the setup.py script.

You can also try this

<li><%= link_to "", application_welcome_path, class: "navbar-brand metas-logo"    %></li>

Where "metas-logo" is a css class with a background image

Create a method to recursively iterate through nested lists. If the current element is an instance of list, then call the same method again. If not, print the current element. Here's an example:

data = [1,2,3,[4,[5,6,7,[8,9]]]]

def print_list(the_list):

    for each_item in the_list:
        if isinstance(each_item, list):
            print_list(each_item)
        else:
            print(each_item)

print_list(data)

import statements are supported in the stable release of Node since version 14.x LTS.

All you need to do is specify "type": "module" in package.json.

First navigate to below location and open it in a text editor

<TOMCAT_HOME>/conf/tomcat-users.xml

For tomcat 7, Add the following xml code somewhere between <tomcat-users>

  <role rolename="manager-gui"/>
  <user username="username" password="password" roles="manager-gui"/>

Now restart the tomcat server.

If you are using angular4 the use below import. it should work .

import 'rxjs/add/operator/map';

If you are using angular5/6 then use map with pipe and import below one

import { map } from "rxjs/operators";

If only one checkbox should be checked in the same time use RadioButtonFor instead:

      @Html.RadioButtonFor(model => model.Type,1, new { @checked = "checked" }) fultime
      @Html.RadioButtonFor(model => model.Type,2) party
      @Html.RadioButtonFor(model => model.Type,3) next option...

If one more one could be checked in the same time use excellent extension: CheckBoxListFor:

Hope,it will help

Let me first explain when and why OOMKiller get invoked?

Say you have 512 RAM + 1GB Swap memory. So in theory, your CPU has access to total of 1.5GB of virtual memory.

Now, for some time everything is running fine within 1.5GB of total memory. But all of sudden (or gradually) your system has started consuming more and more memory and it reached at a point around 95% of total memory used.

Now say any process has requested large chunck of memory from the kernel. Kernel check for the available memory and find that there is no way it can allocate your process more memory. So it will try to free some memory calling/invoking OOMKiller (http://linux-mm.org/OOM).

OOMKiller has its own algorithm to score the rank for every process. Typically which process uses more memory becomes the victim to be killed.

Where can I find logs of OOMKiller?

Typically in /var/log directory. Either /var/log/kern.log or /var/log/dmesg

Hope this will help you.

Some typical solutions:

1. Increase memory (not swap)
2. Find the memory leaks in your program and fix them
3. Restrict memory any process can consume (for example JVM memory can be restricted using JAVA_OPTS)
4. See the logs and google :)

If you need to mix colour from variable and alpha transparency, and with solutions that include rgba() function you get an error like

      background-color: rgba(#{$color}, 0.3);
                       ^
      $color: #002366 is not a color.
   ?
   ¦       background-color: rgba(#{$color}, 0.3);
   ¦                         ^^^^^^^^^^^^^^^^^^^^

Something like this might be useful.

$meeting-room-colors: (
  Neumann: '#002366',
  Turing: '#FF0000',
  Lovelace: '#00BFFF',
  Shared: '#00FF00',
  Chilling: '#FF1493',
);
$color-alpha: EE;

@each $name, $color in $meeting-room-colors {

  .#{$name} {

     background-color: #{$color}#{$color-alpha};

  }

}

You can check if the index of the selected value is 0 or -1 using the selectedIndex property.

In your case 0 is also not a valid index value because its the "placeholder":
<option value="selectcard">--- Please select ---</option>

LIVE DEMO

function Validate()
 {
   var combo = document.getElementById("cardtype");
   if(combo.selectedIndex <=0)
    {
      alert("Please Select Valid Value");
    }
 }

These methods work, if you already have a .vimrc file:

:scriptnames list all the .vim files that Vim loaded for you, including your .vimrc file.

:e $MYVIMRC open & edit the current .vimrc that you are using, then use Ctrl + G to view the path in status bar.

I saw that someone was wondering how to do it for another controller.

In my case I had all of my email templates in the Views/Email folder, but you could modify this to pass in the controller in which you have views associated for.

public static string RenderViewToString(Controller controller, string viewName, object model)
    {
        var oldController = controller.RouteData.Values["controller"].ToString();

        if (controller.GetType() != typeof(EmailController))
            controller.RouteData.Values["controller"] = "Email";

        var oldModel = controller.ViewData.Model;
        controller.ViewData.Model = model;
        try
        {
            using (var sw = new StringWriter())
            {
                var viewResult = ViewEngines.Engines.FindView(controller.ControllerContext, viewName,
                                                                           null);

                var viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
                viewResult.View.Render(viewContext, sw);

                //Cleanup
                controller.ViewData.Model = oldModel;
                controller.RouteData.Values["controller"] = oldController;

                return sw.GetStringBuilder().ToString();
            }
        }
        catch (Exception ex)
        {
            Elmah.ErrorSignal.FromCurrentContext().Raise(ex);

            throw ex;
        }
    }

Essentially what this does is take a controller, such as AccountController and modify it to think it's an EmailController so that the code will look in the Views/Email folder. It's necessary to do this because the FindView method doesn't take a straight up path as a parameter, it wants a ControllerContext.

Once done rendering the string, it returns the AccountController back to its initial state to be used by the Response object.

git reset --hard might do the trick as well

Switches based on integers can be optimized to very efficent code. Switches based on other data type can only be compiled to a series of if() statements.

For that reason C & C++ only allow switches on integer types, since it was pointless with other types.

The designers of C# decided that the style was important, even if there was no advantage.

The designers of Java apparently thought like the designers of C.

This worked perfectly for me.

Step 1:

Select the Project Target-- > Build Settings. Search PROVISIONING_PROFILE and delete whatever nonsense is there.

Step 2:

Uncheck "Automatically manage signing", then check it again and reselect the Team. Xcode then fix whatever was causing the issue on its own.

Here's another (modern) but slightly different version than the ones mentioned before. Tested with IE9:

$('#textareaID').on('input change keyup', function () {
  if (this.value.length) {
    // textarea has content
  } else {
    // textarea is empty
  }
});

For outdated browsers you might also add selectionchange and propertychange (as mentioned in other answers). But selectionchange didn't work for me in IE9. That's why I added keyup.

An additional possible cause.

My HTML page had these starting tags:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

This was on a page that using the slick jquery slideshow.

I removed the tags and replaced with:

<html>

And everything is working again.

Use " instead of " to escape it.

web.config is an XML file so you should use XML escaping.

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

See this forum thread.

Update:

" should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \" and ""?

Update 2:

Try single quotes for the connectionString:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Or:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Update 3:

From MSDN (SqlConnection.ConnectionString Property):

To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.

So:

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

The issue is not with web.config, but the format of the connection string. In a connection string, if you have a " in a value (of the key-value pair), you need to enclose the value in '. So, while Password=somepass"word does not work, Password='somepass"word' does.

if (Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName).Length > 1)
{
  AppLog.Write("Application XXXX already running. Only one instance of this application is allowed", AppLog.LogMessageType.Warn);
  return;
}

Simple utility method:

public static boolean isBetween(int value, int min, int max)
{
  return((value > min) && (value < max));
}

You can use this code snipped to show text with ellipsis

Text(
    "Introduction to Very very very long text",
    maxLines: 1,
    overflow: TextOverflow.ellipsis,
    softWrap: false,
    style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold),
),

For something simple that work for arrays , strings , and objects I builed this function:

function console_testing($var){

    $var = json_encode($var,JSON_UNESCAPED_UNICODE);

    $output = <<<EOT
    <script>
        console.log($var); 
    </script>
EOT;

    echo $output;

}

One common error is leaving a space before the class names. Even if this was the correct syntax:

.menu a:hover .main-nav-item

it never would have worked.

Therefore, you would not write

.menu a .main-nav-item:hover

it would be

.menu a.main-nav-item:hover

One of the challenges I had with the answers is that it assumed that the object was a single level. For example,

const testObj = { testKey: 'testValue' }
const refString = 'testKey';
const refObj = testObj[refString];

works fine, but

const testObj = { testKey:
                  { level2Key: 'level2Value' }
                }
const refString = 'testKey.level2Key';
const refObj = testObj[refString];

does not work.

What I ended up doing was building a function to access multi-level objects:

objVar(str) {
    let obj = this;
    const parts = str.split('.');
    for (let p of parts) {
        obj = obj[p];
    }
    return obj;
}

In the second scenario, then, I can pass the string to this function to get back the object I'm looking for:

const testObj = { testKey:
                  { level2Key: 'level2Value' }
                }
const refString = 'testObj.testKey.level2Key';
const refObj = objVar[refString];

An expression of non-boolean type specified in a context where a condition is expected

I also got this error when I forgot to add ON condition when specifying my join clause.

There's always some reflection hacks that you can adapt. Here is some example, but using a collection would be the solution to your problem (the integers you stick on your variables name is a good hint telling us you should use a collection!).

public class TheClass {

    private int theField= 42;

    public static void main(String[] args) throws Exception {

        TheClass c= new TheClass();

        System.out.println(c.getClass().getDeclaredField("theField").get(c));
    }
}

Very simple method:

.create:before {
content: url(image.png);
}

Works in all modern browsers and IE8+.

Edit

Don't use this on large sites though. The :before pseudo-element is horrible in terms of performance.

To get the list of the enum values you have to use:

enum AnimalEnum {
  DOG = "dog", 
  CAT = "cat", 
  MOUSE = "mouse"
}

Object.values(AnimalEnum);

in pythonwin,

SHIFT + TAB works

Your best bet is to have both repos on your local machine and use the linux diff command with the two directories as parameters:

diff -r repo-A repo-B

The performance of an IF EXISTS statement:

IF EXISTS(SELECT 1 FROM mytable WHERE someColumn = someValue)

depends on the indexes present to satisfy the query.

use for each loop...

ArrayList<Character> al = new ArrayList<>();    
String input="hello";

for (int i = 0; i < input.length(); i++){
    al.add(input.charAt(i));
}

for (Character ch : al) {               
    System.Out.println(ch);             
}

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

Be sure to add this command at the end of every view where you want the validations to be active.

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

Create a class Logger(code below), replace Console.WriteLine with Logger.Out. At the end write to a file the string Log

public static class Logger
{        
     public static StringBuilder LogString = new StringBuilder(); 
     public static void Out(string str)
     {
         Console.WriteLine(str);
         LogString.Append(str).Append(Environment.NewLine);
     }
 }

You could just add a new Variable under the properties of your project Each time you want to get that variable you just have to use

My.Settings.(Name of variable)

That'll work for the entire Project in all forms

According to the Java docs, it looks like you need to use the MemoryImageSource Class to put your byte array into an object in memory, and then use Component.createImage(ImageProducer) next (passing in your MemoryImageSource, which implements ImageProducer).

Here is another solution that works good.

(function() {
    'use strict';

    angular.module('cms').config(route);
    route.$inject = ['$routeProvider'];

    function route($routeProvider) {

        $routeProvider
            .when('/:section', {
                templateUrl: buildPath
            })
            .when('/:section/:page', {
                templateUrl: buildPath
            })
            .when('/:section/:page/:task', {
                templateUrl: buildPath
            });



    }

    function buildPath(path) {

        var layout = 'layout';

        angular.forEach(path, function(value) {

            value = value.charAt(0).toUpperCase() + value.substring(1);
            layout += value;

        });

        layout += '.tpl';

        return 'client/app/layouts/' + layout;

    }

})();

In my case I was including the path to package.egg folder rather than the actual package underneath. I copied the package to top level and it worked.

1. Check the latest Jest (v 0.22): https://github.com/facebook/jest

2. The Facebook team adds the Istanbul code coverage output as part of the coverage report and you can use it directly.

3. After executing Jest, you can get a coverage report in the console and under the root folder set by Jest, you will find the coverage report in JSON and HTML format.

4. FYI, if you install from npm, you might not get the latest version; so try the GitHub first and make sure the coverage is what you need.

Did you try gcc -S -fverbose-asm -O source.c then look into the generated source.s assembler file ?

The generated assembler code goes into source.s (you could override that with -o assembler-filename ); the -fverbose-asm option asks the compiler to emit some assembler comments "explaining" the generated assembler code. The -O option asks the compiler to optimize a bit (it could optimize more with -O2 or -O3).

If you want to understand what gcc is doing try passing -fdump-tree-all but be cautious: you'll get hundreds of dump files.

BTW, GCC is extensible thru plugins or with MELT (a high level domain specific language to extend GCC; which I abandoned in 2017)

I have used the following:

 int index = vpPager.getCurrentItem();
 MyPagerAdapter adapter = ((MyPagerAdapter)vpPager.getAdapter());
 MyFragment suraVersesFragment = (MyFragment)adapter.getRegisteredFragment(index);

Use the Socket() constructor, and connect(SocketAddress endpoint, int timeout) method instead.

In your case it would look something like:

Socket socket = new Socket();
socket.connect(new InetSocketAddress(ipAddress, port), 1000);

Quoting from the documentation

connect

public void connect(SocketAddress endpoint, int timeout) throws IOException

Connects this socket to the server with a specified timeout value. A timeout of zero is interpreted as an infinite timeout. The connection will then block until established or an error occurs.

Parameters:

endpoint - the SocketAddress
timeout - the timeout value to be used in milliseconds.

Throws:

IOException - if an error occurs during the connection
SocketTimeoutException - if timeout expires before connecting
IllegalBlockingModeException - if this socket has an associated channel, and the channel is in non-blocking mode
IllegalArgumentException - if endpoint is null or is a SocketAddress subclass not supported by this socket

Since: 1.4

According to Cliff Click in his 2009 Java One talk A Crash Course in Modern Hardware:

Today, performance is dominated by patterns of memory access. Cache misses dominate – memory is the new disk. [Slide 65]

You can get his full slides here.

Cliff gives an example (finishing on Slide 30) showing that even with the CPU doing register-renaming, branch prediction, and speculative execution, it's only able to start 7 operations in 4 clock cycles before having to block due to two cache misses which take 300 clock cycles to return.

So he says to speed up your program you shouldn't be looking at this sort of minor issue, but on larger ones such as whether you're making unnecessary data format conversions, such as converting "SOAP ? XML ? DOM ? SQL ? …" which "passes all the data through the cache".

The following code works fine for me:

RewriteEngine on 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}\.php -f 
RewriteRule ^(.*)$ $1.php

dmidecode -t 17 | grep  Size:

Adding all above values displayed after "Size: " will give exact total physical size of all RAM sticks in server.

You can make use of getSizeof() as mentioned below to determine the size of an object

import sys
str1 = "one"
int_element=5
print("Memory size of '"+str1+"' = "+str(sys.getsizeof(str1))+ " bytes")
print("Memory size of '"+ str(int_element)+"' = "+str(sys.getsizeof(int_element))+ " bytes")

Use datetime.timetuple() to convert your datetime object to a time.struct_time object then get its tm_yday property:

from datetime import datetime
day_of_year = datetime.now().timetuple().tm_yday  # returns 1 for January 1st

This appear to be default behaviour now, so it's enough to do:

$("#press-enter").on("click", function(){alert("You `clicked' or 'Entered' me!")})

You can try it in this JSFiddle

Tested on: Chrome 56.0 and Firefox (Dev Edition) 54.0a2, both with jQuery 2.2.x and 3.x

The only way I'm aware of is the trick used by FileSaver.js:

1. Create a hidden <a> tag.
2. Set its href attribute to the blob's URL.
3. Set its download attribute to the filename.
4. Click on the <a> tag.

Here is a simplified example (jsfiddle):

var saveData = (function () {
    var a = document.createElement("a");
    document.body.appendChild(a);
    a.style = "display: none";
    return function (data, fileName) {
        var json = JSON.stringify(data),
            blob = new Blob([json], {type: "octet/stream"}),
            url = window.URL.createObjectURL(blob);
        a.href = url;
        a.download = fileName;
        a.click();
        window.URL.revokeObjectURL(url);
    };
}());

var data = { x: 42, s: "hello, world", d: new Date() },
    fileName = "my-download.json";

saveData(data, fileName);

I wrote this example just to illustrate the idea, in production code use FileSaver.js instead.

Notes

• Older browsers don't support the "download" attribute, since it's part of HTML5.
• Some file formats are considered insecure by the browser and the download fails. Saving JSON files with txt extension works for me.

You cant add add items in string array more than its size, i'll suggest you to use ArrayList you can add items dynamically at run time in arrayList if you feel any problem you can freely ask

put your css in public folder, then

add this in you blade file

<link rel="stylesheet" type="text/css" href="{{ asset('mystyle.css') }}">

I would like to share an awesome answer, it might be helpful. Credits Bill Karwin see here https://dba.stackexchange.com/questions/6598/innodb-create-table-error-row-size-too-large

They vary by InnoDB file format.At present there are 2 formats called Antelope and Barracuda.

The central tablespace file (ibdata1) is always in Antelope format. If you use file-per-table, you can make the individual files use Barracuda format by setting innodb_file_format=Barracuda in my.cnf.

Basic points:

1. One 16KB page of InnoDB data must hold at least two rows of data. Plus each page has a header and a footer containing page checksums and log sequence number and so on. That's where you get your limit of a bit less than 8KB per row.

2. Fixed-size data types like INTEGER, DATE, FLOAT, CHAR are stored on this primary data page and count toward the row size limit.

3. Variable-sized data types like VARCHAR, TEXT, BLOB are stored on overflow pages, so they don't count fully toward the row size limit. In Antelope, up to 768 bytes of such columns are stored on the primary data page in addition to being stored on the overflow page. Barracuda supports a dynamic row format, so it may store only a 20-byte pointer on the primary data page.

4. Variable-size data types are also prefixed with 1 or more bytes to encode the length. And InnoDB row format also has an array of field offsets. So there's an internal structure more or less documented in their wiki.

Barracuda also supports a ROW_FORMAT=COMPRESSED to gain further storage efficiency for overflow data.

I also have to comment that I've never seen a well-designed table exceed the row size limit. It's a strong "code smell" that you're violating the repeating groups condition of First Normal Form.

I rewrote the code provided by Ninja2k because I didn't like that it looped through cells. For future reference here's a version using arrays instead which works noticeably faster over lots of ranges but has the same result:

Function concat2(useThis As Range, Optional delim As String) As String
    Dim tempValues
    Dim tempString
    Dim numValues As Long
    Dim i As Long, j As Long
    tempValues = useThis
    numValues = UBound(tempValues) * UBound(tempValues, 2)
    ReDim values(1 To numValues)
    For i = UBound(tempValues) To LBound(tempValues) Step -1
        For j = UBound(tempValues, 2) To LBound(tempValues, 2) Step -1
            values(numValues) = tempValues(i, j)
            numValues = numValues - 1
        Next j
    Next i
    concat2 = Join(values, delim)
End Function

I can't help but think there's definitely a better way...

Here are steps to do it manually without VBA which only works with 1d arrays and makes static values instead of retaining the references:

1. Update cell formula to something like =Sheet2!A1:A15
2. Hit F9
3. Remove the curly braces { and }
4. Place CONCATENATE( at the front of the formula after the = sign and ) at the end of the formula.
5. Hit enter.

If you need to support IE 8 or earlier, you can use jQuery to accomplish this.

var a = [1,2,2,3,4,3,5];
var unique = $.grep(a, function (item, index) {
   return index === $.inArray(item, a);
});

I've used those exists (select * from inserted/deleted) queries for a long time, but it's still not enough for empty CRUD operations (when there're no records in inserted and deleted tables). So after researching this topic a little bit I've found more precise solution:

declare
    @columns_count int = ?? -- number of columns in the table,
    @columns_updated_count int = 0

-- this is kind of long way to get number of actually updated columns
-- from columns_updated() mask, it's better to create helper table
-- or at least function in the real system
with cte_columns as (
    select @columns_count as n
    union all
    select n - 1 from cte_columns where n > 1
), cte_bitmasks as (
    select
        n,
        (n - 1) / 8 + 1 as byte_number,
        power(2, (n - 1) % 8) as bit_mask
    from cte_columns
)
select
    @columns_updated_count = count(*)
from cte_bitmasks as c
where
    convert(varbinary(1), substring(@columns_updated_mask, c.byte_number, 1)) & c.bit_mask > 0

-- actual check
if exists (select * from inserted)
    if exists (select * from deleted)
        select @operation = 'U'
    else
        select @operation = 'I'
else if exists (select * from deleted)
    select @operation = 'D'
else if @columns_updated_count = @columns_count
    select @operation = 'I'
else if @columns_updated_count > 0
    select @operation = 'U'
else
    select @operation = 'D'

It's also possible to use columns_updated() & power(2, column_id - 1) > 0 to see if the column is updated, but it's not safe for tables with big number of columns. I've used a bit complex way of calculating (see helpful article below).

Also, this approach will still incorrectly classifies some updates as inserts (if every column in the table is affected by update), and probably it will classifies inserts where there only default values are inserted as deletes, but those are king of rare operations (at lease in my system they are). Besides that, I don't know how to improve this solution at the moment.

• COLUMNS_UPDATED() for audit triggers by Piotr Rodak
• Dealing with very large bitmasks by Adam Machanic

I found the answer is very very simple...

// It is in java, but it should be same in pyspark
Column col = ds.col("colName"); //the column object
String theNameOftheCol = col.toString();

The variable "theNameOftheCol" is "colName"

You can also perform Implicit Type Conversions with template literals. Example:

let fruits = ["mango","orange","pineapple","papaya"];

console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya

You can use File.WriteAllBytes

Probably not the most efficient, but think it's a neat way to do it.

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "true"));
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "false"));

    }

    static Int32 CountAllTheTimesThisStringAppearsInThatString(string orig, string find)
    {
        var s2 = orig.Replace(find,"");
        return (orig.Length - s2.Length) / find.Length;
    }
}

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

Depending on your python version and how you installed it, it is possible that mysql connector isn't installed, you can install it with pip

To install mysql connector:

pip install mysql-connector-python

Simple solution: 2678400000 is 31 day in milliseconds

var oneMonthFromNow = new Date((+new Date) + 2678400000);

Update:

Use this data to build our own function:

• 2678400000 - 31 day
• 2592000000 - 30 days
• 2505600000 - 29 days
• 2419200000 - 28 days

@Adrien's answer is not working. It gives an ORA-01791.

The correct answer (for the question that is asked) should be:

select id
from 
 (SELECT id, 2 as ordered FROM a -- returns 1,4,2,3
  UNION ALL
  SELECT id, 1 as ordered FROM b -- returns 2,1
  )
group by id
order by min(ordered)

Explanation:

1. The "UNION ALL" is combining the 2 sets. A "UNION" is wastefull because the 2 sets could not be the same, because the ordered field is different.
2. The "group by" is then eliminating duplicates
3. The "order by min (ordered)" is assuring the elements of table b are first

This solves all the cases, even when table b has more or different elements then table a

An example on how to use that would be great. There is a couple of examples at the Qt forum, but you're right that the official documentation should be expanded.

QJsonDocument on its own indeed doesn't produce anything, you will have to add the data to it. That's done through the QJsonObject, QJsonArray and QJsonValue classes. The top-level item needs to be either an array or an object (because 1 is not a valid json document, while {foo: 1} is.)

If you really must use only standard libraries, then you just have to expand on Omar's solution a bit. (Apache's IOUtils is basically just a set of convenience methods which saves on a lot of coding)

You are already able to get the input stream through clobObject.getAsciiStream()

You just have to "manually transfer" the characters to the StringWriter:

InputStream in = clobObject.getAsciiStream();
Reader read = new InputStreamReader(in);
StringWriter write = new StringWriter();

int c = -1;
while ((c = read.read()) != -1)
{
    write.write(c);
}
write.flush();
String s = write.toString();

Bear in mind that

1. If your clob contains more character than would fit a string, this won't work.
2. Wrap the InputStreamReader and StringWriter with BufferedReader and BufferedWriter respectively for better performance.

I'd like to add my experience. In the last few days, I solved an instance of this error in my application. In my particular case, the errors in the code were:

• Removing elements from an STL collection while iterating over it (I believe there are debug flags in Visual Studio to catch these things; I caught it during code review)
• This one is more complex, I'll divide it in steps:
  • From a native C++ thread, call back into managed code
  • In managed land, call Control.Invoke and dispose a managed object which wraps the native object to which the callback belongs.
  • Since the object is still alive inside the native thread (it will remain blocked in the callback call until Control.Invoke ends). I should clarify that I use boost::thread, so I use a member function as the thread function.
  • Solution: Use Control.BeginInvoke (my GUI is made with Winforms) instead so that the native thread can end before the object is destroyed (the callback's purpose is precisely notifying that the thread ended and the object can be destroyed).

Well I found this way :

As a general rule, pop up blockers target windows that launch without user interaction. Usually a click event can open a window without it being blocked. (unless it's a really bad popup blocker)

Try launching after a click event

this works for me try it.

height:1rem;
font-size: 3.75em;

If you are using windows, the PyQt4 folder is not in the path by default, you have to go to it before trying to run it:

c:\Python27\Lib\site-packages\PyQt4\something> pyuic4.exe full/path/to/input.ui -o full/path/to/output.py

or call it using its full path

full/path/to/my/files> c:\Python27\Lib\site-packages\PyQt4\something\pyuic4.exe input.ui -o output.py

Deleting the node folder and restarting works for me(run npm install after restarting)

As mentioned in a different post Read .txt file from workspace groovy script in Jenkins I was struggling to make it work for the pom modules for a file in the workspace, in the Extended Choice Parameter. Here is my solution with the printlns:

import groovy.util.XmlSlurper
import java.util.Map
import jenkins.*
import jenkins.model.*
import hudson.*
import hudson.model.*    

try{
//get Jenkins instance
    def jenkins = Jenkins.instance
//get job Item
    def item = jenkins.getItemByFullName("The_JOB_NAME")
    println item
// get workspacePath for the job Item
    def workspacePath = jenkins.getWorkspaceFor (item)
    println workspacePath

    def file = new File(workspacePath.toString()+"\\pom.xml")
    def pomFile = new XmlSlurper().parse(file)
    def pomModules = pomFile.modules.children().join(",")
    return pomModules
} catch (Exception ex){
    println ex.message
}

You can use:

<a ng-href="#/about">About</a>

If you want some dynamic variable inside href you can do like this way:

<a ng-href="{{link + 123}}">Link to 123</a>

Where link is Angular scope variable.

Increasing column size with ALTER will not lose any data:

alter table [progennet_dev].PROGEN.LE 
    alter column UR_VALUE_3 varchar(500) 

As @Martin points out, remember to explicitly specify NULL | NOT NULL

For the sake of everyone and myself, here is how I use it:

def run_sql(conn_String):
  output_connection = engine.create_engine(conn_string, poolclass=NullPool).connect()
  rows = output_connection.execute('select * from db1.t1').fetchall()  
  return [dict(row) for row in rows]

The difference between constructor and getInitialState is the difference between ES6 and ES5 itself.
getInitialState is used with React.createClass and
constructor is used with React.Component.

Hence the question boils down to advantages/disadvantages of using ES6 or ES5.

Let's look at the difference in code

ES5

var TodoApp = React.createClass({ 
  propTypes: {
    title: PropTypes.string.isRequired
  },
  getInitialState () { 
    return {
      items: []
    }; 
  }
});

ES6

class TodoApp extends React.Component {
  constructor () {
    super()
    this.state = {
      items: []
    }
  }
};

There is an interesting reddit thread regarding this.

React community is moving closer to ES6. Also it is considered as the best practice.

There are some differences between React.createClass and React.Component. For instance, how this is handled in these cases. Read more about such differences in this blogpost and facebook's content on autobinding

constructor can also be used to handle such situations. To bind methods to a component instance, it can be pre-bonded in the constructor. This is a good material to do such cool stuff.

Some more good material on best practices
Best Practices for Component State in React.js
Converting React project from ES5 to ES6

Update: April 9, 2019,:

With the new changes in Javascript class API, you don't need a constructor.

You could do

class TodoApp extends React.Component {

    this.state = {items: []}
};

This will still get transpiled to constructor format, but you won't have to worry about it. you can use this format that is more readable.

With React Hooks

From React version 16.8, there's a new API Called hooks.

Now, you don't even need a class component to have a state. It can even be done in a functional component.

import React, { useState } from 'react';

function TodoApp () {
  const items = useState([]);

Note that the initial state is passed as an argument to useState; useState([])

Read more about react hooks from the official docs
