We use Sphinx in a Vertical Search project with 10.000.000 + of MySql records and 10+ different database . It has got very excellent support for MySQL and high performance on indexing , research is fast but maybe a little less than Lucene. However it's the right choice if you need quickly indexing every day and use a MySQL db.

The identity section goes under the system.web section, not under authentication:

<system.web>
  <authentication mode="Windows"/>
  <identity impersonate="true" userName="foo" password="bar"/>
</system.web>

Probably the simplest way is using subplot2grid, described in Customizing Location of Subplot Using GridSpec.

ax = plt.subplot2grid((2, 2), (0, 0))

is equal to

import matplotlib.gridspec as gridspec
gs = gridspec.GridSpec(2, 2)
ax = plt.subplot(gs[0, 0])

so bmu's example becomes:

import numpy as np
import matplotlib.pyplot as plt

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
fig = plt.figure(figsize=(8, 6))
ax0 = plt.subplot2grid((1, 3), (0, 0), colspan=2)
ax0.plot(x, y)
ax1 = plt.subplot2grid((1, 3), (0, 2))
ax1.plot(y, x)

plt.tight_layout()
plt.savefig('grid_figure.pdf')

use this

public void goToAttract(View v)
{
    Intent intent = new Intent(getActivity(), MainActivityList.class);
    startActivity(intent);
}

be sure you've registered MainActivityList in you Manifest

You can try this:

mean(as.matrix(cluster1))

You can create the path if it doesn't exist yet with a method like the following:

using System.IO;

private void CreateIfMissing(string path)
{
  bool folderExists = Directory.Exists(Server.MapPath(path));
  if (!folderExists)
    Directory.CreateDirectory(Server.MapPath(path));
}

Removing container by force worked for me.

docker rm -f <id_of_the_dead_container>

Notes:

Be aware that this command might throw this error Error response from daemon: Driver devicemapper failed to remove root filesystem <id_of_the_dead_container>: Device is Busy

The mount of your's dead container device mapper should be removed despite this message. That is, you will no longer access this path:

/var/lib/docker/devicemapper/mnt/<id_of_the_dead_container>

If you're using the wonderful ondrej/php ubuntu repository with php7.0:

sudo apt-get install php7.0-pgsql

For ondrej/php Ubuntu repository with php7.1:

sudo apt-get install php7.1-pgsql

Same repository, but for php5.6:

sudo apt-get install php5.6-pgsql

Concise and easy to remember. I love this repository.

Apply the following steps:

1. insert new layout xml in folder layout
2. rename window2
3. add new button and add this line: android:onClick="window2"

mainactivity.java

public void openWindow2(View v) {
        //call window2
        setContentView(R.layout.window2);           
    }
}

In Kotlin you just need to set your string value like this:

<string name="song_number_and_title">"%1$d ~ %2$s"</string>

Create a text view on your layout:

<TextView android:text="@string/song_number_and_title"/>

Then do this in your code if you using Anko:

val song = database.use { // get your song from the database }
song_number_and_title.setText(resources.getString(R.string.song_number_and_title, song.number, song.title))  

You might need to get your resources from the application context.

I encountered this same symptom and none of the solutions above were helpful. I finally got a stack trace of the problem by importing the ear project again to eclipse, and was able to trace this down to the org.eclipse.m2e.wtp.MavenDeploymentDescriptorManagement which was trying to delete a directory in windows' temp directory called ".mavenDeploymentDescriptorManagement", which caused an irrational NullPointerException from the java.io.File.exists() method, particularly because the code already had successfully done the same thing in a previous method with the same variable, then called file.isFile() without problem.

Checking this out on the file system revealed that the file could only be accessed with administrator privileges. Apparently I had at some point launched eclipse from an administrator console by mistake. In the end I just made hidden files visible in windows explorer and deleted the temporary file manually, which solved the problem.

Assuming you build your jar file with ant, you can just instruct ant to leave out the META-INF dir. This is a simplified version of my ant target:

<jar destfile="app.jar" basedir="${classes.dir}">
    <zipfileset excludes="META-INF/**/*" src="${lib.dir}/bcprov-jdk16-145.jar"></zipfileset>
    <manifest>
        <attribute name="Main-Class" value="app.Main"/>
    </manifest>
</jar>

It is difficult to find a regular expression which works for all IPv6 cases. They are usually hard to maintain, not easily readable and may cause performance problems. Hence, I want to share an alternative solution which I have developed: Regular Expression (RegEx) for IPv6 Separate from IPv4

Now you may ask that "This method only finds IPv6, how can I find IPv6 in a text or file?" Here are methods for this issue too.

Note: If you do not want to use IPAddress class in .NET, you can also replace it with my method. It also covers mapped IPv4 and special cases too, while IPAddress does not cover.

class IPv6
{
    public List<string> FindIPv6InFile(string filePath)
    {
        Char ch;
        StringBuilder sbIPv6 = new StringBuilder();
        List<string> listIPv6 = new List<string>();
        StreamReader reader = new StreamReader(filePath);
        do
        {
            bool hasColon = false;
            int length = 0;

            do
            {
                ch = (char)reader.Read();

                if (IsEscapeChar(ch))
                    break;

                //Check the first 5 chars, if it has colon, then continue appending to stringbuilder
                if (!hasColon && length < 5)
                {
                    if (ch == ':')
                    {
                        hasColon = true;
                    }
                    sbIPv6.Append(ch.ToString());
                }
                else if (hasColon) //if no colon in first 5 chars, then dont append to stringbuilder
                {
                    sbIPv6.Append(ch.ToString());
                }

                length++;

            } while (!reader.EndOfStream);

            if (hasColon && !listIPv6.Contains(sbIPv6.ToString()) && IsIPv6(sbIPv6.ToString()))
            {
                listIPv6.Add(sbIPv6.ToString());
            }

            sbIPv6.Clear();

        } while (!reader.EndOfStream);
        reader.Close();
        reader.Dispose();

        return listIPv6;
    }

    public List<string> FindIPv6InText(string text)
    {
        StringBuilder sbIPv6 = new StringBuilder();
        List<string> listIPv6 = new List<string>();

        for (int i = 0; i < text.Length; i++)

                }

                length++;

            } while (i + length != text.Length);

            if (hasColon && !listIPv6.Contains(sbIPv6.ToString()) && IsIPv6(sbIPv6.ToString()))
            {
                listIPv6.Add(sbIPv6.ToString());

            i += length;

        {
            return ip.AddressFamily == AddressFamily.InterNetworkV6;

        }
    }

A little late, but here's a regex I found that returns 0 matches for empty or white spaces:

/^(?!\s*$).+/

You can test this out at regex101

If you also use jQueryUI, you get a (simple) version of the :data selector with it that checks for the presence of a data item, so you can do something like $("div:data(view)"), or $( this ).closest(":data(view)").

See http://api.jqueryui.com/data-selector/ . I don't know for how long they've had it, but it's there now!

I would like to refer a previous question, Because I have faced same problem and solved by this solution. First of all a constraint is always built with a Hash value in it's name. So problem is this HASH is varies in different Machine or Database. For example DF__Companies__IsGlo__6AB17FE4 here 6AB17FE4 is the hash value(8 bit). So I am referring a single script which will be fruitful to all

DECLARE @Command NVARCHAR(MAX)
     declare @table_name nvarchar(256)
     declare @col_name nvarchar(256)
     set @table_name = N'ProcedureAlerts'
     set @col_name = N'EmailSent'

     select @Command ='Alter Table dbo.ProcedureAlerts Drop Constraint [' + ( select d.name
     from 
         sys.tables t
         join sys.default_constraints d on d.parent_object_id = t.object_id
         join sys.columns c on c.object_id = t.object_id
                               and c.column_id = d.parent_column_id
     where 
         t.name = @table_name
         and c.name = @col_name) + ']'

    --print @Command
    exec sp_executesql @Command

It will drop your default constraint. However if you want to create it again you can simply try this

ALTER TABLE [dbo].[ProcedureAlerts] ADD DEFAULT((0)) FOR [EmailSent]

Finally, just simply run a DROP command to drop the column.

Do not set the background-color inside the print stylesheet. Just set the attribute in the normal css file and it works fine :)

You have to override your ; delimiter with something like $$ to avoid this kind of error.

After your function definition, you can set the delimiter back to ;.

This should work:

DELIMITER $$
CREATE FUNCTION F_Dist3D (x1 decimal, y1 decimal) 
RETURNS decimal
DETERMINISTIC
BEGIN 
  DECLARE dist decimal;
  SET dist = SQRT(x1 - y1);
  RETURN dist;
END$$
DELIMITER ;

Using iText (existing PDF in bytes)

    public static byte[] mergePDF(List<byte[]> pdfFilesAsByteArray) throws DocumentException, IOException {

    ByteArrayOutputStream outStream = new ByteArrayOutputStream();
    Document document = null;
    PdfCopy writer = null;

    for (byte[] pdfByteArray : pdfFilesAsByteArray) {

        try {
            PdfReader reader = new PdfReader(pdfByteArray);
            int numberOfPages = reader.getNumberOfPages();

            if (document == null) {
                document = new Document(reader.getPageSizeWithRotation(1));
                writer = new PdfCopy(document, outStream); // new
                document.open();
            }
            PdfImportedPage page;
            for (int i = 0; i < numberOfPages;) {
                ++i;
                page = writer.getImportedPage(reader, i);
                writer.addPage(page);
            }
        }

        catch (Exception e) {
            e.printStackTrace();
        }

    }

    document.close();
    outStream.close();
    return outStream.toByteArray();

}

Using plain old JavaScript worked for me:
document.querySelector('#elementName').click();

You may use clang as well. It used to be faster than GCC, and now it is quite a stable thing. It is much easier to build clang from sources (you can really drink cup of coffee during build process).

In short:

1. Get clang binaries (sudo apt-get install clang).. or download and build (read instructions here)
2. Mount your raspberry rootfs (it may be the real rootfs mounted via sshfs, or an image).

3. Compile your code:

   path/to/clang --target=arm-linux-gnueabihf --sysroot=/some/path/arm-linux-gnueabihf/sysroot my-happy-program.c -fuse-ld=lld
   

Optionally you may use legacy arm-linux-gnueabihf binutils. Then you may remove "-fuse-ld=lld" flag at the end.

Differences might not be meaningful in a typical use case, but using the standard DOM functionality

$("#el")[0].outerHTML

is about twice as fast as

$("<div />").append($("#el").clone()).html();

so I would go with:

/* 
 * Return outerHTML for the first element in a jQuery object,
 * or an empty string if the jQuery object is empty;  
 */
jQuery.fn.outerHTML = function() {
   return (this[0]) ? this[0].outerHTML : '';  
};

You should use profiles.

<profiles>
    <profile>
        <id>otherOutputDir</id>
        <build>
            <directory>yourDirectory</directory>
        </build>
    </profile>
</profiles>

And start maven with your profile

mvn compile -PotherOutputDir

If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :

<properties>
    <buildDirectory>${project.basedir}/target</buildDirectory>
</properties>

<build>
    <directory>${buildDirectory}</directory>
</build>

And compile like this :

mvn compile -DbuildDirectory=test

That's because you can't change the target directory by using -Dproject.build.directory

This is the correct way.

>>> x = [ ['0,0', '0,1'], ['1,0', '1,1'], ['2,0', '2,1'] ]
>>> for i in range(len(x)):
        for j in range(len(x[i])):
                print(x[i][j])


0,0
0,1
1,0
1,1
2,0
2,1
>>> 

AFAIK you can't do that.
What I did at my place of work, is transfer the files to your home (~) folder (or really any folder that you have full permissions in, i.e chmod 777 or variants) via WinSCP, and then SSH to to your linux machine and sudo from there to your destination folder.

Another solution would be to change permissions of the directories you are planning on uploading the files to, so your user (which is without sudo privileges) could write to those dirs.

I would also read about WinSCP Remote Commands for further detail.

I've had this problem. See The Python "Connection Reset By Peer" Problem.

You have (most likely) run afoul of small timing issues based on the Python Global Interpreter Lock.

You can (sometimes) correct this with a time.sleep(0.01) placed strategically.

"Where?" you ask. Beats me. The idea is to provide some better thread concurrency in and around the client requests. Try putting it just before you make the request so that the GIL is reset and the Python interpreter can clear out any pending threads.

For Windows HTTP, you can't beat Fiddler. You can use it as a reverse proxy for port-forwarding on a web server. It doesn't necessarily need IE, either. It can use other clients.

First, which version of ubuntu are you using, it might be easiest to just upgrade to one that has it.

Next, enable backports (system menue, adminstration, software sources), and search for in in synaptic.

Last, look for a ppa for it.

You can use an inflater with TableRow:

for (int i = 0; i < months; i++) {
    
    View view = getLayoutInflater ().inflate (R.layout.list_month_data, null, false);
        
    TextView textView = view.findViewById (R.id.title);
    
    textView.setText ("Text");
        
    tableLayout.addView (view);
    
}

Layout:

<TableRow
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_centerInParent="true"
    android:gravity="center_horizontal"
    android:paddingTop="15dp"
    android:paddingRight="15dp"
    android:paddingLeft="15dp"
    android:paddingBottom="10dp"
    >
    
    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="18sp"
        android:gravity="center"
        />
    
</TableRow>

CMake favours passing the full path to link libraries, so assuming libbingitup.a is in ${CMAKE_SOURCE_DIR}, doing the following should succeed:

add_executable(main main.cpp)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libbingitup.a)

The easiest way to fix this is to add a new factor to your column. Use the levels function to determine how many factors you have and then add a new factor.

    > levels(data$Fireplace.Qu)
    [1] "Ex" "Fa" "Gd" "Po" "TA"
    > levels(data$Fireplace.Qu) = c("Ex", "Fa", "Gd", "Po", "TA", "None")
    [1] "Ex"   "Fa"   "Gd"   "Po"   " TA"  "None"

You need to write it like sprintf(aa, "%9.7lf", a)

Check out http://en.wikipedia.org/wiki/Printf for some more details on format codes.

Fatal error: Can't use function return value in write context

This usually happens when using a function directly with empty.

Example:

if (empty(is_null(null))) {
  echo 'empty';
}

This is because empty is a language construct and not a function, it cannot be called with an expression as its argument in PHP versions before 5.5. Prior to PHP 5.5, the argument to empty() must be a variable, but an arbitrary expression (such as a return value of a function) is permissible in PHP 5.5+.

empty, despite its name, does not actually check if a variable is "empty". Instead, it checks if a variable doesn't exist, or == false. Expressions (like is_null(null) in the example) will always be deemed to exist, so here empty is only checking if it is equal to false. You could replace empty() here with !, e.g. if (!is_null(null)), or explicitly compare to false, e.g. if (is_null(null) == false).

Just to add to Shahid's answer - you can account for orientation changes or different devices using this (iOS7+):

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

DEMO

You cannot achieve the desired solution with CSS z-index either, as z-index is only relative to the parent element. So if you have parents A and B with respective children a and b, b's z-index is only relative to other children of B and a's z-index is only relative to other children of A.

The z-index of A and B are relative to each other if they share the same parent element, but all of the children of one will share the same relative z-index at this level.

start_date = datetime.strptime('8/18/2008', "%m/%d/%Y")

Make file executable:

chmod +x file

Find location of perl:

which perl

This should return something like

/bin/perl sometimes /usr/local/bin

Then in the first line of your script add:

#!"path"/perl with path from above e.g.

#!/bin/perl

Then you can execute the file

./file

There may be some issues with the PATH, so you may want to change that as well ...

Instead of triggering the native file-download dialog like so:

By DOWNLOAD_ANCHOR = By.partialLinkText("download");
driver.findElement(DOWNLOAD_ANCHOR).click();

I usually do this instead, to bypass the native File Download dialog. This way it works on ALL browsers:

String downloadURL = driver.findElement(DOWNLOAD_ANCHOR).getAttribute("href");
File downloadedFile = getFileFromURL(downloadURL);

This just requires that you implement method getFileFromURL that uses Apache HttpClient to download a file and return a File reference to you.

Similarly, if you happen to be using Selenide, it works the same way using the built-in download() function for handling file downloads.

This can be achieved using div. It can be done with table too. But i always prefer div.

<body id="doc-body" style="width: 100%; height: 100%; overflow: hidden; position: fixed" onload="InitApp()"> 
    <div>
        <!--If you don't need header background color you don't need this div.-->
        <div id="div-header-hack" style="height: 20px; position: absolute; background-color: gray"></div>

        <div id="div-header" style="position: absolute; top: 0px; overflow: hidden; height: 20px; background-color: gray">                
        </div>

        <div id="div-item" style="position: absolute; top: 20px; overflow: auto" onscroll="ScrollHeader()">                
        </div>
    </div>
</body>

Javascript:
please refer jsFiddle for this part. Else this answer becomes very lengthy.

I don't know if this is still going. But something like this is what I ended up using (I keep a session object on each connected socket, which in turn contains the username and other info:

var connectedUsers = Object.keys(io.sockets.connected).map(function(socketId) {
    return io.sockets.connected[socketId].session.username;
});

Solution for this issue is:

1. Create another connection manager for your excel or flat files else you just have to pass variable values in connection string:

2. Right Click on Connection Manager>>properties>>Expression >>Select "ConnectionString" from drop down and pass the input variable like path , filename ..

As others have pointed out, using the * operator for a mutable object duplicates references, so if you change one you change them all. If you want to create independent instances of a mutable object, your xrange syntax is the most Pythonic way to do this. If you are bothered by having a named variable that is never used, you can use the anonymous underscore variable.

[e for _ in xrange(n)]

Have you added the dll into your project references list? If not right click on the project "References" folder and selecet "Add Reference" then use browse to locate your science.dll, select it and click ok.

I can't see the image of your VS instance that some people are referring to and I note that you now say that it works in Net4.0 and VS2010.

VS2008 projects support NET 3.5 by default. I expect that is the problem as your DLL may be NET 4.0 compliant but not NET 3.5.

For example,

package main

import "fmt"

func main() {
    type Map1 map[string]interface{}
    type Map2 map[string]int
    m := Map1{"foo": Map2{"first": 1}, "boo": Map2{"second": 2}}
    //m = map[foo:map[first: 1] boo: map[second: 2]]
    fmt.Println("m:", m)
    for k, v := range m {
        fmt.Println("k:", k, "v:", v)
    }
}

Output:

m: map[boo:map[second:2] foo:map[first:1]]
k: boo v: map[second:2]
k: foo v: map[first:1]

The transcript mode is what you want and is used by Google Talk and the SMS/MMS application. Are you correctly calling notifyDatasetChanged() on your adapter when you add items?

This will set your number of mysql connection unti (Requires SUPER privileges).

There is a lot of confusion around lambdas and closures, even in the answers to this StackOverflow question here. Instead of asking random programmers who learned about closures from practice with certain programming languages or other clueless programmers, take a journey to the source (where it all began). And since lambdas and closures come from Lambda Calculus invented by Alonzo Church back in the '30s before first electronic computers even existed, this is the source I'm talking about.

Lambda Calculus is the simplest programming language in the world. The only things you can do in it:?

• APPLICATION: Applying one expression to another, denoted f x.
  (Think of it as a function call, where f is the function and x is its only parameter)
• ABSTRACTION: Binds a symbol occurring in an expression to mark that this symbol is just a "slot", a blank box waiting to be filled with value, a "variable" as it were. It is done by prepending a Greek letter ? (lambda), then the symbolic name (e.g. x), then a dot . before the expression. This then converts the expression into a function expecting one parameter.
  For example: ?x.x+2 takes the expression x+2 and tells that the symbol x in this expression is a bound variable – it can be substituted with a value you supply as a parameter.
  Note that the function defined this way is anonymous – it doesn't have a name, so you can't refer to it yet, but you can immediately call it (remember application?) by supplying it the parameter it is waiting for, like this: (?x.x+2) 7. Then the expression (in this case a literal value) 7 is substituted as x in the subexpression x+2 of the applied lambda, so you get 7+2, which then reduces to 9 by common arithmetics rules.

So we've solved one of the mysteries:
lambda is the anonymous function from the example above, ?x.x+2.

function(x) { return x+2; }

and you can immediately apply it to some parameter like this:

(function(x) { return x+2; })(7)

or you can store this anonymous function (lambda) into some variable:

var f = function(x) { return x+2; }

which effectively gives it a name f, allowing you to refer to it and call it multiple times later, e.g.:

alert(  f(7) + f(10)  );   // should print 21 in the message box

But you didn't have to name it. You could call it immediately:

alert(  function(x) { return x+2; } (7)  );  // should print 9 in the message box

In LISP, lambdas are made like this:

(lambda (x) (+ x 2))

and you can call such a lambda by applying it immediately to a parameter:

(  (lambda (x) (+ x 2))  7  )

As I said, what the lambda abstraction does is binding a symbol in its subexpression, so that it becomes a substitutible parameter. Such a symbol is called bound. But what if there are other symbols in the expression? For example: ?x.x/y+2. In this expression, the symbol x is bound by the lambda abstraction ?x. preceding it. But the other symbol, y, is not bound – it is free. We don't know what it is and where it comes from, so we don't know what it means and what value it represents, and therefore we cannot evaluate that expression until we figure out what y means.

In fact, the same goes with the other two symbols, 2 and +. It's just that we are so familiar with these two symbols that we usually forget that the computer doesn't know them and we need to tell it what they mean by defining them somewhere, e.g. in a library or the language itself.

You can think of the free symbols as defined somewhere else, outside the expression, in its "surrounding context", which is called its environment. The environment might be a bigger expression that this expression is a part of (as Qui-Gon Jinn said: "There's always a bigger fish" ;) ), or in some library, or in the language itself (as a primitive).

This lets us divide lambda expressions into two categories:

• CLOSED expressions: every symbol that occurs in these expressions is bound by some lambda abstraction. In other words, they are self-contained; they don't require any surrounding context to be evaluated. They are also called combinators.
• OPEN expressions: some symbols in these expressions are not bound – that is, some of the symbols occurring in them are free and they require some external information, and thus they cannot be evaluated until you supply the definitions of these symbols.

You can CLOSE an open lambda expression by supplying the environment, which defines all these free symbols by binding them to some values (which may be numbers, strings, anonymous functions aka lambdas, whatever…).

And here comes the closure part:
The closure of a lambda expression is this particular set of symbols defined in the outer context (environment) that give values to the free symbols in this expression, making them non-free anymore. It turns an open lambda expression, which still contains some "undefined" free symbols, into a closed one, which doesn't have any free symbols anymore.

For example, if you have the following lambda expression: ?x.x/y+2, the symbol x is bound, while the symbol y is free, therefore the expression is open and cannot be evaluated unless you say what y means (and the same with + and 2, which are also free). But suppose that you also have an environment like this:

{  y: 3,
+: [built-in addition],
2: [built-in number],
q: 42,
w: 5  }

This environment supplies definitions for all the "undefined" (free) symbols from our lambda expression (y, +, 2), and several extra symbols (q, w). The symbols that we need to be defined are this subset of the environment:

{  y: 3,
+: [built-in addition],
2: [built-in number]  }

and this is precisely the closure of our lambda expression :>

In other words, it closes an open lambda expression. This is where the name closure came from in the first place, and this is why so many people's answers in this thread are not quite correct :P

Well, the corporate marketoids of Sun/Oracle, Microsoft, Google etc. are to blame, because that's what they called these constructs in their languages (Java, C#, Go etc.). They often call "closures" what are supposed to be just lambdas. Or they call "closures" a particular technique they used to implement lexical scoping, that is, the fact that a function can access the variables that were defined in its outer scope at the time of its definition. They often say that the function "encloses" these variables, that is, captures them into some data structure to save them from being destroyed after the outer function finishes executing. But this is just made-up post factum "folklore etymology" and marketing, which only makes things more confusing, because every language vendor uses its own terminology.

And it's even worse because of the fact that there's always a bit of truth in what they say, which does not allow you to easily dismiss it as false :P Let me explain:

If you want to implement a language that uses lambdas as first-class citizens, you need to allow them to use symbols defined in their surrounding context (that is, to use free variables in your lambdas). And these symbols must be there even when the surrounding function returns. The problem is that these symbols are bound to some local storage of the function (usually on the call stack), which won't be there anymore when the function returns. Therefore, in order for a lambda to work the way you expect, you need to somehow "capture" all these free variables from its outer context and save them for later, even when the outer context will be gone. That is, you need to find the closure of your lambda (all these external variables it uses) and store it somewhere else (either by making a copy, or by preparing space for them upfront, somewhere else than on the stack). The actual method you use to achieve this goal is an "implementation detail" of your language. What's important here is the closure, which is the set of free variables from the environment of your lambda that need to be saved somewhere.

It didn't took too long for people to start calling the actual data structure they use in their language's implementations to implement closure as the "closure" itself. The structure usually looks something like this:

Closure {
   [pointer to the lambda function's machine code],
   [pointer to the lambda function's environment]
}

and these data structures are being passed around as parameters to other functions, returned from functions, and stored in variables, to represent lambdas, and allowing them to access their enclosing environment as well as the machine code to run in that context. But it's just a way (one of many) to implement closure, not the closure itself.

As I explained above, the closure of a lambda expression is the subset of definitions in its environment that give values to the free variables contained in that lambda expression, effectively closing the expression (turning an open lambda expression, which cannot be evaluated yet, into a closed lambda expression, which can then be evaluated, since all the symbols contained in it are now defined).

Anything else is just a "cargo cult" and "voo-doo magic" of programmers and language vendors unaware of the real roots of these notions.

I hope that answers your questions. But if you had any follow-up questions, feel free to ask them in the comments, and I'll try to explain it better.

The most common ones I see in production code are (in this order):

myFunctionName     // lower camel case

MyFunctionName     // upper camel case

my_function_name   // K & R ?

I find the naming convention a programmer uses in C++ code usually has something to do with their programming background.

E.g. ex-java programmers tend to use lower camel case for functions

You should be using the json module. json.dumps(string). It can also serialize other python data types.

import json

>>> s = 'my string with "double quotes" blablabla'

>>> json.dumps(s)
<<< '"my string with \\"double quotes\\" blablabla"'

409 Conflict could be an acceptable solution.

According to: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

The doc continues with an example:

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

In my case, I would like to PUT a string, that must be unique, to a database via an API. Before adding it to the database, I am checking that it is not already in the database.

If it is, I will return "Error: The string is already in the database", 409.

I believe this is what the OP wanted: an error code suitable for when the data does not pass the server's criteria.

Below code is self-explanatory, We can use an enum with a switch case:

/**
 *
 */
enum ClassNames {
    STRING(String.class, String.class.getSimpleName()),
    BOOLEAN(Boolean.class, Boolean.class.getSimpleName()),
    INTEGER(Integer.class, Integer.class.getSimpleName()),
    LONG(Long.class, Long.class.getSimpleName());
    private Class typeName;
    private String simpleName;
    ClassNames(Class typeName, String simpleName){
        this.typeName = typeName;
        this.simpleName = simpleName;
    }
}

Based on the class values from the enum can be mapped:

 switch (ClassNames.valueOf(clazz.getSimpleName())) {
        case STRING:
            String castValue = (String) keyValue;
            break;
        case BOOLEAN:
            break;
        case Integer:
            break;
        case LONG:
            break;
        default:
            isValid = false;

    }

Hope it helps :)

May be it is the problem of using len() for an integer value. does not posses the len attribute in Python.

Error as:I will give u an example:

Instead of use ths,

data = [1,2,3,4]
print(len(data))

First step is to check sessionStorage for some pre-defined value and if it exists alert user:

if (sessionStorage.getItem("is_reloaded")) alert('Reloaded!');

Second step is to set sessionStorage to some value (for example true):

sessionStorage.setItem("is_reloaded", true);

Session values kept until page is closed so it will work only if page reloaded in a new tab with the site. You can also keep reload count the same way.

Check if /usr/bin has 'javac'. If not you have installed JRE & have to install jdk dev version like "java-1.8.0-openjdk-devel.x86_64"

function get_format($df) {

    $str = '';
    $str .= ($df->invert == 1) ? ' - ' : '';
    if ($df->y > 0) {
        // years
        $str .= ($df->y > 1) ? $df->y . ' Years ' : $df->y . ' Year ';
    } if ($df->m > 0) {
        // month
        $str .= ($df->m > 1) ? $df->m . ' Months ' : $df->m . ' Month ';
    } if ($df->d > 0) {
        // days
        $str .= ($df->d > 1) ? $df->d . ' Days ' : $df->d . ' Day ';
    } 

    echo $str;
}

$yr=$year;
$dates=$dor;
$myyear='+'.$yr.' years';
$new_date = date('Y-m-d', strtotime($myyear, strtotime($dates)));
$date1 = new DateTime("$new_date");
$date2 = new DateTime("now");
$diff = $date2->diff($date1);

You can also use the Grid View its also Responsive its something like this:

#wrapper {
   width: auto;
    height: auto;
    box-sizing: border-box;
    display: grid;
    grid-auto-flow: row;
    grid-template-columns: repeat(6, 1fr);
}

#left{
    text-align: left;
    grid-column: 1/4;
}

#right {
    text-align: right;
    grid-column: 4/6;
}

and the HTML should look like this :

<div id="wrapper">
<div id="left" > ...some awesome stuff </div>
<div id="right" > ...some awesome stuff </div>
</div>

here is a link for more information:

im quite new but i thougt i could share my little experience

For using the new progress bar

style="?android:attr/progressBarStyleHorizontal"

for the old grey color progress bar use

style="@android:style/Widget.ProgressBar.Horizontal"

in this one you have the option of changing the height by setting minHeight

The complete XML code is:

    <ProgressBar
    android:id="@+id/pbProcessing"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/tvProcessing"
    android:indeterminateOnly="true"/>

indeterminateOnly is set to true for getting indeterminate horizontal progress bar

I'd like to add one additional piece of information since the accepted answer above didn't fix my errors completely.

In my scenario, I have a parent component, which holds a child component. And that child component also contains another component.

So, my parent component's spec file need to have the declaration of the child component, AS WELL AS THE CHILD'S CHILD COMPONENT. That finally fixed the issue for me.

matches method performs matching of full line, i.e. it is equivalent to find() with '^abc$'. So, just use Pattern.compile("[a-zA-Z]").matcher(str).find() instead. Then fix your regex. As @user unknown mentioned your regex actually matches only one character. You probably should say [a-zA-Z]+

This is exactly what I wanted to do. I was not sure of the previous command git cherry-pick C, it sounds nice but it seems you do this to get changes from another branch but not on same branch, has anyone tried it?

So I did something else which also worked : I got the files I wanted back from the old commit file by file

git checkout <commit-hash> <filename>

ex : git checkout 08a6497b76ad098a5f7eda3e4ec89e8032a4da51 file.css

-> this takes the files as they were from the old commit

Then I did my changes. And I committed again.

git status (to check which files were modified)
git diff (to check the changes you made)
git add .
git commit -m "my message"

I checked my history with git log, and I still have my history along with my new changes made from the old files. And I could push too.

Note that to go back to the state you want you need to put the hash of the commit before the unwanted changes. Also make sure you don't have uncommitted changes before you do that.

See the end of this post for how to do this in WAMPServer 3

For WampServer 2.5 and previous versions

WAMPServer is designed to be a single seat developers tool. Apache is therefore configure by default to only allow access from the PC running the server i.e. localhost or 127.0.0.1 or ::1

But as it is a full version of Apache all you need is a little knowledge of the server you are using.

The simple ( hammer to crack a nut ) way is to use the 'Put Online' wampmanager menu option.

left click wampmanager icon -> Put Online

This however tells Apache it can accept connections from any ip address in the universe. That's not a problem as long as you have not port forwarded port 80 on your router, or never ever will attempt to in the future.

The more sensible way is to edit the httpd.conf file ( again using the wampmanager menu's ) and change the Apache access security manually.

left click wampmanager icon -> Apache -> httpd.conf

This launches the httpd.conf file in notepad.

Look for this section of this file

<Directory "d:/wamp/www">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride All

    #
    # Controls who can get stuff from this server.
    #
#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
</Directory>

Now assuming your local network subnet uses the address range 192.168.0.?

Add this line after Allow from localhost

Allow from 192.168.0

This will tell Apache that it is allowed to be accessed from any ip address on that subnet. Of course you will need to check that your router is set to use the 192.168.0 range.

This is simply done by entering this command from a command window ipconfig and looking at the line labeled IPv4 Address. you then use the first 3 sections of the address you see in there.

For example if yours looked like this:-

IPv4 Address. . . . . . . . . . . : 192.168.2.11

You would use

Allow from 192.168.2

UPDATE for Apache 2.4 users

Of course if you are using Apache 2.4 the syntax for this has changed.

You should replace ALL of this section :

Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
Allow from localhost

With this, using the new Apache 2.4 syntax

Require local
Require ip 192.168.0

You should not just add this into httpd.conf it must be a replace.

For WAMPServer 3 and above

In WAMPServer 3 there is a Virtual Host defined by default. Therefore the above suggestions do not work. You no longer need to make ANY amendments to the httpd.conf file. You should leave it exactly as you find it.

Instead, leave the server OFFLINE as this funtionality is defunct and no longer works, which is why the Online/Offline menu has become optional and turned off by default.

Now you should edit the \wamp\bin\apache\apache{version}\conf\extra\httpd-vhosts.conf file. In WAMPServer3.0.6 and above there is actually a menu that will open this file in your editor

left click wampmanager -> Apache -> httpd-vhost.conf

just like the one that has always existsed that edits your httpd.conf file.

It should look like this if you have not added any of your own Virtual Hosts

#
# Virtual Hosts
#

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot c:/wamp/www
    <Directory  "c:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require local
    </Directory>
</VirtualHost>

Now simply change the Require parameter to suite your needs EG

If you want to allow access from anywhere replace Require local with

Require all granted

If you want to be more specific and secure and only allow ip addresses within your subnet add access rights like this to allow any PC in your subnet

Require local
Require ip 192.168.1

Or to be even more specific

Require local
Require ip 192.168.1.100
Require ip 192.168.1.101

Using the code below you can extend the partial context class with a method that will take a collection of entity objects and bulk copy them to the database. Simply replace the name of the class from MyEntities to whatever your entity class is named and add it to your project, in the correct namespace. After that all you need to do is call the BulkInsertAll method handing over the entity objects you want to insert. Do not reuse the context class, instead create a new instance every time you use it. This is required, at least in some versions of EF, since the authentication data associated with the SQLConnection used here gets lost after having used the class once. I don't know why.

This version is for EF 5

No, this is not possible. In documents that make use of CSS, an inline style attribute can only contain property declarations; the same set of statements that appears in each ruleset in a stylesheet. From the Style Attributes spec:

The value of the style attribute must match the syntax of the contents of a CSS declaration block (excluding the delimiting braces), whose formal grammar is given below in the terms and conventions of the CSS core grammar:

declaration-list
  : S* declaration? [ ';' S* declaration? ]*
  ;

Neither selectors (including pseudo-elements), nor at-rules, nor any other CSS construct are allowed.

Think of inline styles as the styles applied to some anonymous super-specific ID selector: those styles only apply to that one very element with the style attribute. (They take precedence over an ID selector in a stylesheet too, if that element has that ID.) Technically it doesn't work like that; this is just to help you understand why the attribute doesn't support pseudo-class or pseudo-element styles (it has more to do with how pseudo-classes and pseudo-elements provide abstractions of the document tree that can't be expressed in the document language).

Note that inline styles participate in the same cascade as selectors in rule sets, and take highest precedence in the cascade (!important notwithstanding). So they take precedence even over pseudo-class states. Allowing pseudo-classes or any other selectors in inline styles would possibly introduce a new cascade level, and with it a new set of complications.

Note also that very old revisions of the Style Attributes spec did originally propose allowing this, however it was scrapped, presumably for the reason given above, or because implementing it was not a viable option.

If you're using NuGet it is worth going to 'Manage NuGet Packages For Solution', finding the package which is causing issues and hitting update. It should then bring all of the packages up to the latest version and resolve the problem.

Worth a shot as it's a quick and easy.

I tried all settings mentioned in this post to build my project successfully however that didn't work for me. At last I was able to build my project successfully with mvn -DargLine=-Dfile.encoding=UTF-8 clean insall command.

You have to set a default value.

ALTER TABLE mytable ADD COLUMN mycolumn character varying(50) NOT NULL DEFAULT 'foo';

... some work (set real values as you want)...

ALTER TABLE mytable ALTER COLUMN mycolumn DROP DEFAULT;

I got the same error, but when i did as below, it resolved the issue.
Instead of writing like this:

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

use the below one:

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

std::stoi from string could also be used.

    #include <string>

    using namespace std;

    int main (int argc, char** argv)
    {
         if (argc >= 2)
         {
             int val = stoi(argv[1]);
             // ...    
         }
         return 0;
    }

With Objective C class methods, we can just avoid using the singleton pattern the usual way, from:

[[Librarian sharedInstance] openLibrary]

to:

[Librarian openLibrary]

by wrapping the class inside another class that just has Class Methods, that way there is no chance of accidentally creating duplicate instances, as we're not creating any instance!

I wrote a more detailed blog here :)

I believe the problem with "go to" packages is that they would work diferently for each language.

If you use Javascript js-hyperclick and hyperclick (since code-links is deprecated) may do what you need.

Use symbols-view package which let your search and jump to functions declaration but just of current opened file. Unfortunately, I don't know of any other language's equivalent.

There is also another package which could be useful for go-to in Python: python-tools

As of May 2016, recent version of Atom now support "Go-To" natively. At the GitHub repo for this module you get a list of the following keys:

• symbols-view:toggle-file-symbols to Show all symbols in current file
• symbols-view:toggle-project-symbols to Show all symbols in the project
• symbols-view:go-to-declaration to Jump to the symbol under the cursor
• symbols-view:return-from-declaration to Return from the jump

I now only have one thing missing with Atom for this: mouse click bindings. There's an open issue on Github if anyone want to follow that feature.

The solution is not very efficient as pointed by Erwin, because of presence of SubQs

select * from purchases p1 where total in
(select max(total) from purchases where p1.customer=customer) order by total desc;

p is the conversion specifier to print pointers. Use this.

int a = 42;

printf("%p\n", (void *) &a);

Remember that omitting the cast is undefined behavior and that printing with p conversion specifier is done in an implementation-defined manner.

Just run this in a console.

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
cinst powershell

It installs the latest version using a Chocolatey repository.

Originally I was using command cinst powershell 3.0.20121027, but it looks like it later stopped working. Since this question is related to PowerShell 3.0 this was the right way. At this moment (June 26, 2014) cinst powershell refers to version 3.0 of PowerShell, and that may change in future.

See the Chocolatey PowerShell package page for details on what version will be installed.

The issue is not with the with statement, it is on the Range function, it doesn't accept the absolute cell value.. it should be like Range("A4:B100").. you can refer the following thread for reference..

following code should work.. Convert cells(1,1) into "A1" and vice versa

LastColData = Sheets(WSNAME).Range("A4").End(xlToRight).Column
            LastRowData = Sheets(WSNAME).Range("A4").End(xlDown).Row
            Rng = "A4:" & Sheets(WSNAME).Cells(LastRowData, LastColData).Address(RowAbsolute:=False, ColumnAbsolute:=False)

 Worksheets(WSNAME).Range(Rng).ClearContents

Annotation that binds a method parameter or method return value to a named model attribute, exposed to a web view.

public String add(@ModelAttribute("specified") Model model) {
    ...
}

Try this one:

p.pos_fixed {
    position:fixed;
    top:30px;
    right:5px;
}

I found a very beautiful recursive (even functional) Breadth-First traversal related algorithm. Not my idea, but i think it should be mentioned in this topic.

Chris Okasaki explains his breadth-first numbering algorithm from ICFP 2000 at http://okasaki.blogspot.de/2008/07/breadth-first-numbering-algorithm-in.html very clearly with only 3 pictures.

The Scala implementation of Debasish Ghosh, which i found at http://debasishg.blogspot.de/2008/09/breadth-first-numbering-okasakis.html, is:

trait Tree[+T]
case class Node[+T](data: T, left: Tree[T], right: Tree[T]) extends Tree[T]
case object E extends Tree[Nothing]

def bfsNumForest[T](i: Int, trees: Queue[Tree[T]]): Queue[Tree[Int]] = {
  if (trees.isEmpty) Queue.Empty
  else {
    trees.dequeue match {
      case (E, ts) =>
        bfsNumForest(i, ts).enqueue[Tree[Int]](E)
      case (Node(d, l, r), ts) =>
        val q = ts.enqueue(l, r)
        val qq = bfsNumForest(i+1, q)
        val (bb, qqq) = qq.dequeue
        val (aa, tss) = qqq.dequeue
        tss.enqueue[org.dg.collection.BFSNumber.Tree[Int]](Node(i, aa, bb))
    }
  }
}

def bfsNumTree[T](t: Tree[T]): Tree[Int] = {
  val q = Queue.Empty.enqueue[Tree[T]](t)
  val qq = bfsNumForest(1, q)
  qq.dequeue._1
}

There are several ways of checking if an variable is an array or not. The best solution is the one you have chosen.

variable.constructor === Array

This is the fastest method on Chrome, and most likely all other browsers. All arrays are objects, so checking the constructor property is a fast process for JavaScript engines.

If you are having issues with finding out if an objects property is an array, you must first check if the property is there.

variable.prop && variable.prop.constructor === Array

Some other ways are:

Array.isArray(variable)

Update May 23, 2019 using Chrome 75, shout out to @AnduAndrici for having me revisit this with his question This last one is, in my opinion the ugliest, and it is one of the slowest fastest. Running about 1/5 the speed as the first example. This guy is about 2-5% slower, but it's pretty hard to tell. Solid to use! Quite impressed by the outcome. Array.prototype, is actually an array. you can read more about it here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/isArray

variable instanceof Array

This method runs about 1/3 the speed as the first example. Still pretty solid, looks cleaner, if you're all about pretty code and not so much on performance. Note that checking for numbers does not work as variable instanceof Number always returns false. Update: instanceof now goes 2/3 the speed!

So yet another update

Object.prototype.toString.call(variable) === '[object Array]';

This guy is the slowest for trying to check for an Array. However, this is a one stop shop for any type you're looking for. However, since you're looking for an array, just use the fastest method above.

Also, I ran some test: http://jsperf.com/instanceof-array-vs-array-isarray/35 So have some fun and check it out.

Note: @EscapeNetscape has created another test as jsperf.com is down. http://jsben.ch/#/QgYAV I wanted to make sure the original link stay for whenever jsperf comes back online.

The standard advice, promoted by the Yahoo! Exceptional Performance team, is to put the <script> tags at the end of the document body so they don't block rendering of the page.

But there are some newer approaches that offer better performance, as described in this answer about the load time of the Google Analytics JavaScript file:

There are some great slides by Steve Souders (client-side performance expert) about:

• Different techniques to load external JavaScript files in parallel
• their effect on loading time and page rendering
• what kind of "in progress" indicators the browser displays (e.g. 'loading' in the status bar, hourglass mouse cursor).

this works for me:

from tkinter import *
root = Tk()
l = Label(root, text="Does it work")
l.pack()

For TamperMonkey:

@grant window.close 

Ref: https://www.tampermonkey.net/documentation.php#_grant

For a PHP approach, you can use mysql_field_flags

$q = mysql_query('select * from table limit 1');

for($i = 0; $i < mysql_num_fields(); $i++)
    if(strpos(mysql_field_tags($q, $i), 'primary_key') !== false)
        echo mysql_field_name($q, $i)." is a primary key\n";

It may be time consuming to get all the application Ids from YARN and kill them one by one. You can use a Bash for loop to accomplish this repetitive task quickly and more efficiently as shown below:

Kill all applications on YARN which are in ACCEPTED state:

for x in $(yarn application -list -appStates ACCEPTED | awk 'NR > 2 { print $1 }'); do yarn application -kill $x; done

Kill all applications on YARN which are in RUNNING state:

for x in $(yarn application -list -appStates RUNNING | awk 'NR > 2 { print $1 }'); do yarn application -kill $x; done

I've figure it out the solution to my problem:

• Step 1: from within the vSphere client, while connected to vCenter1, select the VM and then from "File" menu select "Export"->"Export OVF Template" (Note: make sure the VM is Powered Off otherwise this feature is not available - it will be gray). This action will allow you to save on your machine/laptop the VM (as an .vmdk, .ovf and a .mf file).
• Step 2: Connect to the vCenter2 with your vSphere client and from "File" menu select "Deploy OVF Template..." and then select the location where the VM was saved in the previous step.

That was all!
Thanks!

With Ansible 1.9 or later

Ansible uses the become, become_user, and become_method directives to achieve privilege escalation. You can apply them to an entire play or playbook, set them in an included playbook, or set them for a particular task.

- name: checkout repo
  git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
  become: yes
  become_user: some_user

You can use become_with to specify how the privilege escalation is achieved, the default being sudo.

The directive is in effect for the scope of the block in which it is used (examples).

See Hosts and Users for some additional examples and Become (Privilege Escalation) for more detailed documentation.

In addition to the task-scoped become and become_user directives, Ansible 1.9 added some new variables and command line options to set these values for the duration of a play in the absence of explicit directives:

• Command line options for the equivalent become/become_user directives.
• Connection specific variables which can be set per host or group.

As of Ansible 2.0.2.0, the older sudo/sudo_user syntax described below still works, but the deprecation notice states, "This feature will be removed in a future release."

Previous syntax, deprecated as of Ansible 1.9 and scheduled for removal:

- name: checkout repo
  git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
  sudo: yes
  sudo_user: some_user

Instead of adding the line breaks with nl2br() and then removing the line breaks with explode(), try using the line break character '\r' or '\n' or '\r\n'.

<?php     $options= file_get_contents("employees.txt");     $options=explode("\n",$options);        // try \r as well.      foreach ($options as $singleOption){         echo "<option value='".$singleOption."'>".$singleOption."</option>";     }   ?> 

This could also fix the issue if the problem was due to Google Spreadsheets reading the line breaks.

You're on the right track. You may read the user input into an integer and switch on that:

enum Choice
{
  EASY = 1, 
  MEDIUM = 2, 
  HARD = 3
};

int i = -1;

// ...<present the user with a menu>...

cin >> i;

switch(i)
{
  case EASY:
    cout << "Easy\n";
    break;
  case MEDIUM:
    cout << "Medium\n";
    break;
  case HARD:
    cout << "Hard\n";
    break;
  default:
    cout << "Invalid Selection\n";
    break;
}

Using @EmbeddableId for the PK entity has solved my issue.

@Entity
@Table(name="SAMPLE")
 public class SampleEntity implements Serializable{
   private static final long serialVersionUID = 1L;

   @EmbeddedId
   SampleEntityPK id;

 }

You can use a jQuery plugin: jQuery Array Utilities

For example the code below

$.union([1, 2, 2, 3], [2, 3, 4, 5, 5])

will return [1,2,3,4,5]

var curDate=new Date();
var startDate=document.forms[0].m_strStartDate;

var endDate=document.forms[0].m_strEndDate;
var startDateVal=startDate.value.split('-');
var endDateVal=endDate.value.split('-');
var firstDate=new Date();
firstDate.setFullYear(startDateVal[2], (startDateVal[1] - 1), startDateVal[0]);

var secondDate=new Date();
secondDate.setFullYear(endDateVal[2], (endDateVal[1] - 1), endDateVal[0]);
if(firstDate > curDate) {
    alert("Start date cannot be greater than current date!");
    return false;
}
if (firstDate > secondDate) {
    alert("Start date cannot be greater!");
    return false;
}

1. Go to Google Fonts https://fonts.google.com/

The problem is that what you are trying to do shouldn't be done. You shouldn't be inflating fragments inside other fragments. From Android's documentation:

Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.

While you may be able to accomplish the task with the hacks presented here, I highly suggest you don't do it. Its impossible to be sure that these hacks will handle what each new Android OS does when you try to inflate a layout for a fragment containing another fragment.

The only Android-supported way to add a fragment to another fragment is via a transaction from the child fragment manager.

Simply change your XML layout into an empty container (add an ID if needed):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapFragmentContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
</LinearLayout>

Then in the Fragment onViewCreated(View view, @Nullable Bundle savedInstanceState) method:

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    FragmentManager fm = getChildFragmentManager();
    SupportMapFragment mapFragment = (SupportMapFragment) fm.findFragmentByTag("mapFragment");
    if (mapFragment == null) {
        mapFragment = new SupportMapFragment();
        FragmentTransaction ft = fm.beginTransaction();
        ft.add(R.id.mapFragmentContainer, mapFragment, "mapFragment");
        ft.commit();
        fm.executePendingTransactions();
    }
    mapFragment.getMapAsync(callback);
}

See this answer. val() is comparing a string, not a numeric value.

For android 4.2, dont forget to add @JavascriptInterface to all javasscript functions

Try This:

using System;
using System.Configuration;
using System.Web.Configuration;

namespace SampleApplication.WebConfig
{
    public partial class webConfigFile : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //Helps to open the Root level web.config file.
            Configuration webConfigApp = WebConfigurationManager.OpenWebConfiguration("~");
            //Modifying the AppKey from AppValue to AppValue1
            webConfigApp.AppSettings.Settings["ConnectionString"].Value = "ConnectionString";
            //Save the Modified settings of AppSettings.
            webConfigApp.Save();
        }
    }
}

protected void Page_Load(object sender, EventArgs e)
    {
        // prevent user from making operation twice
        btnSave.Attributes.Add("onclick", 
                               "this.disabled=true;" + GetPostBackEventReference(btnSave).ToString() + ";");

        // ... etc. 
    }

I found the game library Allegro easy to use back in the day. Might be worth a look.

I had the same problem , first I couldn't find those dlls in the list of .NET components . but later I figured it out that the solution is :

1- first I changed target framework from .NET framework 4 client profile to .NET framework 4.

2- then scroll down the list of .NET components , pass first list of system.web... , scroll down , and find the second list of system.web... at the bottom , they're there .

I hope this could help others

I bet your machine's culture is not "en-US". From the documentation:

If provider is a null reference (Nothing in Visual Basic), the current culture is used.

If your current culture is not "en-US", this would explain why it works for me but doesn't work for you and works when you explicitly specify the culture to be "en-US".

It only opens the first (bookmarked) page full screen. Any next page will be opened WITH the address bar visible again. Whatever meta tag you put into your page header...

you can use cmd \k at the end of your script to see the error. it won't close your command prompt after the execution is done

import numpy as np

n = 51 #number of data points
# Suppose the real and imaginary parts are created independently
real_part = np.random.normal(size=n)
imag_part = np.random.normal(size=n)

# Create a complex array - the imaginary part will be equal to zero
z = np.array(real_part, dtype=complex)
# Now define the imaginary part:
z.imag = imag_part
print(z)

I found them useful in a situation when I wanted to declare a handler for some control's event, using another control. To do it normally you would have to store controls' references in fields of the class so that you could use them in a different method than they were created.

private ComboBox combo;
private Label label;

public CreateControls()
{
    combo = new ComboBox();
    label = new Label();
    //some initializing code
    combo.SelectedIndexChanged += new EventHandler(combo_SelectedIndexChanged);
}

void combo_SelectedIndexChanged(object sender, EventArgs e)
{
    label.Text = combo.SelectedValue;
}

thanks to lambda expressions you can use it like this:

public CreateControls()
{
    ComboBox combo = new ComboBox();
    Label label = new Label();
    //some initializing code
    combo.SelectedIndexChanged += (s, e) => {label.Text = combo.SelectedValue;};
}

Much easier.

Okay This may sound Dumb but it worked for me.

as a total beginner, I didn't realized that writing:

router.post("/", (res, req) => {
  console.log(req.body);
  req.send("User Route");
});

is wrong !

You have make sure that you pass parameters(req,res) of post/get in right order: and call them accordingly:

router.post("/", (req, res) => {
  console.log(req.body);
  res.send("User Route");
});

Here is a nearly complete example javascript function that will allow multiple markers defined in a JSONObject.

It will only display the markers that are with in the bounds of the map.

This is important so you are not doing extra work.

You can also set a limit to the markers so you are not showing an extreme amount of markers (if there is a possibility of a thing in your usage);

it will also not display markers if the center of the map has not changed more than 500 meters.
This is important because if a user clicks on the marker and accidentally drags the map while doing so you don't want the map to reload the markers.

I attached this function to the idle event listener for the map so markers will show only when the map is idle and will redisplay the markers after a different event.

In action screen shot there is a little change in the screen shot showing more content in the infowindow. pasted from pastbin.com

<script src="//pastebin.com/embed_js/uWAbRxfg"></script>

it's as simple as this

$.post({url: "som_page.php", 
    data: { data1: value1, data2: value2 }
    ).done(function( data ) { 
        $( "body" ).html(data);
    });
});

I had to solve this to make a screen lock of my application where I had to pass sensitive data as user and the url where he was working. Then create a function that executes this code

String.split seems to be much slower than StringTokenizer. The only advantage with split is that you get an array of the tokens. Also you can use any regular expressions in split. org.apache.commons.lang.StringUtils has a split method which works much more faster than any of two viz. StringTokenizer or String.split. But the CPU utilization for all the three is nearly the same. So we also need a method which is less CPU intensive, which I am still not able to find.

Your most elegant solution must be:

var left: Node? = null

fun show() {
    left?.also {
        queue.add( it )
    }
}

Then you don't have to define a new and unnecessary local variable, and you don't have any new assertions or casts (which are not DRY). Other scope functions could also work so choose your favourite.

Use the method setAnimation(null) to stop an animation, it exposed as public method in View.java, it is the base class for all widgets, which are used to create interactive UI components (buttons, text fields, etc.). /** * Sets the next animation to play for this view. * If you want the animation to play immediately, use * {@link #startAnimation(android.view.animation.Animation)} instead. * This method provides allows fine-grained * control over the start time and invalidation, but you * must make sure that 1) the animation has a start time set, and * 2) the view's parent (which controls animations on its children) * will be invalidated when the animation is supposed to * start. * * @param animation The next animation, or null. */ public void setAnimation(Animation animation)

In Swift:

let globalPoint = aView.superview?.convertPoint(aView.frame.origin, toView: nil)

It works for me in Oxygen.

1) Go to Help > Eclipse Marketplace... and search for "DLTK". You'll find something like "Shell Script (DLTK) 5.8.0". Install it and reboot Eclipse.

(Or drag'n'drop "Install" button from this web page to your Eclipse: https://marketplace.eclipse.org/content/shell-script-dltk)

2) Right-click on the shell/batch file in Project Explorer > Open With > Other... and select Shell Script Editor. You can also associate the editor with all files of that extension.

In PrimeFaces 3.0, that style get applied on the generated inner <div> of the table cell, not on the <td> as you (and I) would expect. The following example should work out for you:

<p:dataTable styleClass="myTable">

with

.myTable td:nth-child(1) {
    width: 20px;
}

In PrimeFaces 3.5 and above, it should work exactly the way you coded and expected.

in your tsconfig you have to add: "esModuleInterop": true - it should help.

Using JExamXML with java application

    import com.a7soft.examxml.Options;

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

       // Reads two XML files into two strings
       String s1 = readFile("orders1.xml");
       String s2 = readFile("orders.xml");

       // Loads options saved in a property file
       Options.loadOptions("options");

       // Compares two Strings representing XML entities
       System.out.println( ExamXML.compareXMLString( s1, s2 ) );

Use socat for this:

For example:

socat PTY,link=/dev/ttyS10 PTY,link=/dev/ttyS11

In my case got a working solution through Cross-document Messaging (XDM) and Executing Chrome extension onclick instead of page load.

manifest.json

        "myscript.js"
      ]
    }
  ],

  "background": {
    "scripts": [
      "background.js"
    ]
  }

}

background.js

chrome.browserAction.onClicked.addListener(function (tab) {
  chrome.tabs.query({active: true, currentWindow: true}, function (tabs) {
    var activeTab = tabs[0];
    chrome.tabs.sendMessage(activeTab.id, {"message": "clicked_browser_action"});
  });
});

myscript.js

chrome.runtime.onMessage.addListener(
    function (request, sender, sendResponse) {
        if (request.message === "clicked_browser_action") {
        console.log('Hello world!')
        }
    }
);

Your code is fine, just replace the following line:

JSONArray jsonMainArr = new JSONArray(mainJSON.getJSONArray("source"));

with this line:

JSONArray jsonMainArr = mainJSON.getJSONArray("source");

The worst way:

>>> def hex_to_int(x):
    return eval("0x" + x)

>>> hex_to_int("c0ffee")
12648430

Please don't do this!

Is using eval in Python a bad practice?

use jQuery.live() instead . Documentation here

e.g

$("mylink").live("click", function(event) { alert("new link clicked!");});

Adding one more scalable solution.

lists = [lst1, lst2, lst3, lst4]
df = pd.concat([pd.Series(x) for x in lists], axis=1)

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

If you use Bootstrap 3 and everything works fine on other browsers except IE, try the below.

1. Download the JDK
2. Install it
3. Then Setup environment variables like this :
4. Click on EDIT

5. Then click PATH, Click Add , Then Add it like this:

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

If you need access to the resources of a library project (as you do with ABS) ensure that you add the library project/module as a "Module Dependency" instead of a "Library".

Try jQuery.inArray()

Here is a jsfiddle link using the same code : http://jsfiddle.net/yrshaikh/SUKn2/

The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0

Example Code :

<html>
   <head>
      <style>
         div { color:blue; }
         span { color:red; }
  </style>
      <script src="http://code.jquery.com/jquery-latest.js"></script>
   </head>
   <body>    
      <div>"John" found at <span></span></div>
      <div>4 found at <span></span></div>
      <div>"Karl" not found, so <span></span></div>
      <div>
         "Pete" is in the array, but not at or after index 2, so <span></span>
      </div>
      <script>
         var arr = [ 4, "Pete", 8, "John" ];
         var $spans = $("span");
         $spans.eq(0).text(jQuery.inArray("John", arr));
         $spans.eq(1).text(jQuery.inArray(4, arr));
         $spans.eq(2).text(jQuery.inArray("Karl", arr));
         $spans.eq(3).text(jQuery.inArray("Pete", arr, 2));
      </script>  
   </body>
</html>

Output:

"John" found at 3
4 found at 0
"Karl" not found, so -1
"Pete" is in the array, but not at or after index 2, so -1

Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.

First, some definitions:

1. There are TypeNames, which are string representations of the type of an object, interface, etc. For example, Bar is a TypeName in Public Class Bar, or in Dim Foo as Bar. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.
2. There are System.Type objects which contain a value. This value indicates a type; just like a String would take some text or an Int would take a number, except we are storing types instead of text or numbers. Type objects contain the type definitions, as well as its corresponding TypeName.

Second, the theory:

1. Foo.GetType() returns a Type object which contains the type for the variable Foo. In other words, it tells you what Foo is an instance of.
2. GetType(Bar) returns a Type object which contains the type for the TypeName Bar.

3. In some instances, the type an object has been Cast to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer cast into an Object:

   Dim MyVal As Integer = 42 Dim MyObj As Object = CType(MyVal, Object)

So, is MyObj of type Object or of type Integer? MyObj.GetType() will tell you it is an Integer.

4. But here comes the Type Of Foo Is Bar feature, which allows you to ascertain a variable Foo is compatible with a TypeName Bar. Type Of MyObj Is Integer and Type Of MyObj Is Object will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it. More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarks

The test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.

Public Sub TestMethod1()

    Dim MyValInt As Integer = 42
    Dim MyValDble As Double = CType(MyValInt, Double)
    Dim MyObj As Object = CType(MyValDble, Object)

    Debug.Print(MyValInt.GetType.ToString) 'Returns System.Int32
    Debug.Print(MyValDble.GetType.ToString) 'Returns System.Double
    Debug.Print(MyObj.GetType.ToString) 'Returns System.Double

    Debug.Print(MyValInt.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyValDble.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyObj.GetType.GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(GetType(Integer).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Double).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Object).GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(MyValInt.GetType = GetType(Integer)) '# Returns True
    Debug.Print(MyValInt.GetType = GetType(Double)) 'Returns False
    Debug.Print(MyValInt.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyValDble.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyObj.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyObj.GetType = GetType(Object)) 'Returns False

    Debug.Print(TypeOf MyObj Is Integer) 'Returns False
    Debug.Print(TypeOf MyObj Is Double) '# Returns True
    Debug.Print(TypeOf MyObj Is Object) '# Returns True


End Sub

EDIT

You can also use Information.TypeName(Object) to get the TypeName of a given object. For example,

Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"

in case of the IPv4 protocol, the server with one IP address that listens on one port only can handle 2^32 IP addresses x 2^16 ports so 2^48 unique sockets. If you speak about a server as a physical machine, and you are able to utilize all 2^16 ports, then there could be maximum of 2^48 x 2^16 = 2^64 unique TCP/IP sockets for one IP address. Please note that some ports are reserved for the OS, so this number will be lower. To sum up:

1 IP and 1 port --> 2^48 sockets

1 IP and all ports --> 2^64 sockets

all unique IPv4 sockets in the universe --> 2^96 sockets

Try adding this line to the xml parent layout

 android:animateLayoutChanges="true"

Your layout will look like this

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:animateLayoutChanges="true"
    android:longClickable="false"
    android:orientation="vertical"
    android:weightSum="16">

    .......other code here

    </LinearLayout>

Another, unfortunately highly OS-dependent, solution is memory mapping the file. The benefits generally include performance of the read, and reduced memory use as the applications view and operating systems file cache can actually share the physical memory.

POSIX code would look like this:

int fd = open("filename", O_RDONLY);
int len = lseek(fd, 0, SEEK_END);
void *data = mmap(0, len, PROT_READ, MAP_PRIVATE, fd, 0);

Windows on the other hand is little more tricky, and unfortunately I don't have a compiler in front of me to test, but the functionality is provided by CreateFileMapping() and MapViewOfFile().

SELECT COLUMN_NAME, TABLE_NAME,table_schema
FROM INFORMATION_SCHEMA.COLUMNS;

array_push — Push one or more elements onto the end of array

Take note of the words "one or more elements onto the end" to do that using $arr[] you would have to get the max size of the array

First of all, install and save them in package.json:

npm i --save jquery
npm i --save jquery-ui-dist

Secondly, add a alias in webpack configuration:

resolve: {
  root: [
    path.resolve(__dirname, '../node_modules'),
    path.resolve(__dirname, '../src'),
  ],
  alias: {
    'jquery-ui': 'jquery-ui-dist/jquery-ui.js'
  },
  extensions: ['', '.js', '.json'],
}

It work for me with the last jquery(3.2.1) and jquery-ui(1.12.1).

See my blog for detail: http://code.tonytuan.org/2017/03/webpack-import-jquery-ui-in-es6-syntax.html

Check that ORACLE_HOME environment variable is pointing to the correct oracle home. In my case it was changed by another software installation.

If you want to build DOM you can use jsdom.

There's also cheerio, it has the jQuery interface and it's a lot faster than older versions of jsdom, although these days they are similar in performance.

You might wanna have a look at htmlparser2, which is a streaming parser, and according to its benchmark, it seems to be faster than others, and no DOM by default. It can also produce a DOM, as it is also bundled with a handler that creates a DOM. This is the parser that is used by cheerio.

parse5 also looks like a good solution. It's fairly active (11 days since the last commit as of this update), WHATWG-compliant, and is used in jsdom, Angular, and Polymer.

And if you want to parse HTML for web scraping, you can use YQL¹. There is a node module for it. YQL I think would be the best solution if your HTML is from a static website, since you are relying on a service, not your own code and processing power. Though note that it won't work if the page is disallowed by the robot.txt of the website, YQL won't work with it.

If the website you're trying to scrape is dynamic then you should be using a headless browser like phantomjs. Also have a look at casperjs, if you're considering phantomjs. And you can control casperjs from node with SpookyJS.

Beside phantomjs there's zombiejs. Unlike phantomjs that cannot be embedded in nodejs, zombiejs is just a node module.

There's a nettuts+ toturial for the latter solutions.

¹ Since Aug. 2014, YUI library, which is a requirement for YQL, is no longer actively maintained, source

HTML:

<body ng-app="App">
    <div ng-controller="testController" >
        <input type="hidden" id="testInput" ng-model="testInput" ng-init="testInput=123" />
    </div>
    {{ testInput }}
</body>

JS:

angular.module('App', []);

testController = function ($scope) {
    console.log('test');
    $scope.$watch('testInput', testShow, true);
    function testShow() {
      console.log($scope.testInput);
    }
}

Fiddle

just the numbers:

$('input.time').keydown(function(e) { if(e.keyCode>=48 && e.keyCode<=57) { return true; } else { return false; } });

or for time including ":"

$('input.time').keydown(function(e) { if(e.keyCode>=48 && e.keyCode<=58) { return true; } else { return false; } });

also including delete and backspace:

$('input.time').keydown(function(e) { if((e.keyCode>=46 && e.keyCode<=58) || e.keyCode==8) { return true; } else { return false; } });

unfortuneatly not getting it to work on a iMAC

When you click on compose email in Gmail notice that the url changes from https://mail.google.com/mail/u/0/#inbox to https://mail.google.com/mail/u/0/#inbox?compose=new. Now when you enter say a email id [email protected] , the value for compose changes now the url became https://mail.google.com/mail/u/0/#inbox?compose=150b0f7ffb682642.

So this is working fine with my html hyperlink until the account is signed in, but if the account is not signed in it would take me the login page and when I enter the credentials somehow this compose value is lost and this does not work.

Close terminal, delete the folder where your project is, then clone again your project and voilá.

In a batch file solution

for /R c:\source %%f in (*.xml) do copy %%f x:\destination\

The code works as such;

for each file for in directory c:\source and subdirectories /R that match pattern (\*.xml) put the file name in variable %%f, then for each file do copy file copy %%f to destination x:\\destination\\

Just tested it here on my Windows XP computer and it worked like a treat for me. But I typed it into command prompt so I used the single %f variable name version, as described in the linked question above.

According to my research there is no way to do this exactly the way you want. You can manually re-create the table and copy the data, or SSMS can (and will) do this for you (when you drag and drop a column to a different order, it does this). In fact it souldn't matter what order the columns are... As an alternative solution you can select the data you want in the order you desired. For example, instead of using asterisk (*) in select, specify the column names in some order... Lets say MyTable has col1, col2, col3, colNew columns.

Instead of:

SELECT * FROM MyTable

You can use:

SELECT col1, colNew, col2, col3 FROM MyTable

for getting Hash map first element you can use bellow code in kotlin:

val data : Float = hashMap?.get(hashMap?.keys?.first())

Answering this old question (for others which may help)

Configuring your httpd conf correctly will make the problem solved. Install any httpd server, if you don't have one.

Listing my config here.

[smilyface@box002 ~]$ cat /etc/httpd/conf/httpd.conf | grep shirts | grep -v "#"

        ProxyPass /shirts-service http://local.box002.com:16743/shirts-service
        ProxyPassReverse /shirts-service http://local.box002.com:16743/shirts-service
        ProxyPass /shirts http://local.box002.com:16443/shirts
        ProxyPassReverse /shirts http://local.box002.com:16443/shirts
        ...
        ...
        ...

edit the file as above and then restart httpd as below

[smilyface@box002 ~]$ sudo service httpd restart

And then request with with https will work without exception.
Also request with http will forward to https ! No worries.

You can use the re module for regexes, but regexes are probably overkill for what you want. I might try something like

z.write(article[:article.index("</html>") + 7]

This is much cleaner, and should be much faster than a regex based solution.

if you're using jQuery you would have:

$('#elementId').change(function() { alert('Do Stuff'); });

or MS AJAX:

$addHandler($get('elementId'), 'change', function(){ alert('Do Stuff'); });

Or in the raw HTML of the element:

<input type="text" onchange="alert('Do Stuff');" id="myElement" />

After re-reading the question I think I miss-read what was to be done. I've never found a way to update a DOM element in a manner which will force a change event, what you're best doing is having a separate event handler method, like this:

$addHandler($get('elementId'), 'change', elementChanged);
function elementChanged(){
  alert('Do Stuff!');
}
function editElement(){
  var el = $get('elementId');
  el.value = 'something new';
  elementChanged();
}

Since you're already writing a JavaScript method which will do the changing it's only 1 additional line to call.

Or, if you are using the Microsoft AJAX framework you can access all the event handlers via:

$get('elementId')._events

It'd allow you to do some reflection-style workings to find the right event handler(s) to fire.

This might be a bit of a hack, but I avoided the issue and converted the json into PHP's POST array on the server side:

$_POST = json_decode(file_get_contents('php://input'), true);

You are using jQuery, right? Separate JavaScript from HTML.

You can use trigger or triggerHandler.

var $myInput = $('#changeProgramatic').on('change', ChangeValue);

var anotherFunction = function() {
  $myInput.val('Another value');
  $myInput.trigger('change');
};

The volatile and transient modifiers can be applied to fields of classes¹ irrespective of field type. Apart from that, they are unrelated.

The transient modifier tells the Java object serialization subsystem to exclude the field when serializing an instance of the class. When the object is then deserialized, the field will be initialized to the default value; i.e. null for a reference type, and zero or false for a primitive type. Note that the JLS (see 8.3.1.3) does not say what transient means, but defers to the Java Object Serialization Specification. Other serialization mechanisms may pay attention to a field's transient-ness. Or they may ignore it.

(Note that the JLS permits a static field to be declared as transient. This combination doesn't make sense for Java Object Serialization, since it doesn't serialize statics anyway. However, it could make sense in other contexts, so there is some justification for not forbidding it outright.)

The volatile modifier tells the JVM that writes to the field should always be synchronously flushed to memory, and that reads of the field should always read from memory. This means that fields marked as volatile can be safely accessed and updated in a multi-thread application without using native or standard library-based synchronization. Similarly, reads and writes to volatile fields are atomic. (This does not apply to >>non-volatile<< long or double fields, which may be subject to "word tearing" on some JVMs.) The relevant parts of the JLS are 8.3.1.4, 17.4 and 17.7.

How to show uncommitted changes in Git

The command you are looking for is git diff.

git diff - Show changes between commits, commit and working tree, etc

Here are some of the options it expose which you can use

git diff (no parameters)
Print out differences between your working directory and the index.

git diff --cached:
Print out differences between the index and HEAD (current commit).

git diff HEAD:
Print out differences between your working directory and the HEAD.

git diff --name-only
Show only names of changed files.

git diff --name-status
Show only names and status of changed files.

git diff --color-words
Word by word diff instead of line by line.

Here is a sample of the output for git diff --color-words:

I'd a similar problem in a legacy application, but de "--" was string parameter.

Ex.:

Dim cmd As New OracleCommand("INSERT INTO USER (name, address, photo) VALUES ('User1', '--', :photo)", oracleConnection)
Dim fs As IO.FileStream = New IO.FileStream("c:\img.jpg", IO.FileMode.Open)
Dim br As New IO.BinaryReader(fs)
cmd.Parameters.Add(New OracleParameter("photo", OracleDbType.Blob)).Value = br.ReadBytes(fs.Length)
cmd.ExecuteNonQuery() 'here throws ORA-01008

Changing address parameter value '--' to '00' or other thing, works.

You need to place the \n in double quotes.
Inside single quotes it is treated as 2 characters '\' followed by 'n'

You need:

$str = str_replace("\n", '', $str);

A better alternative is to use PHP_EOL as:

$str = str_replace(PHP_EOL, '', $str);

Here is a method I use to both iterate an enum and provide multiple values types from one enum

enum IterateEnum: Int {
    case Zero
    case One
    case Two
    case Three
    case Four
    case Five
    case Six
    case Seven

    //tuple allows multiple values to be derived from the enum case, and
    //since it is using a switch with no default, if a new case is added,
    //a compiler error will be returned if it doesn't have a value tuple set
    var value: (french: String, spanish: String, japanese: String) {
        switch self {
        case .Zero: return (french: "zéro", spanish: "cero", japanese: "nuru")
        case .One: return (french: "un", spanish: "uno", japanese: "ichi")
        case .Two: return (french: "deux", spanish: "dos", japanese: "ni")
        case .Three: return (french: "trois", spanish: "tres", japanese: "san")
        case .Four: return (french: "quatre", spanish: "cuatro", japanese: "shi")
        case .Five: return (french: "cinq", spanish: "cinco", japanese: "go")
        case .Six: return (french: "six", spanish: "seis", japanese: "roku")
        case .Seven: return (french: "sept", spanish: "siete", japanese: "shichi")
        }
    }

    //Used to iterate enum or otherwise access enum case by index order.
    //Iterate by looping until it returns nil
    static func item(index: Int) -> IterateEnum? {
        return IterateEnum.init(rawValue: index)
    }

    static func numberFromSpanish(number: String) -> IterateEnum? {
        return findItem { $0.value.spanish == number }
    }

    //use block to test value property to retrieve the enum case        
    static func findItem(predicate: ((_: IterateEnum) -> Bool)) -> IterateEnum? {

        var enumIndex: Int = -1
        var enumCase: IterateEnum?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = IterateEnum.item(index: enumIndex)

            if let eCase = enumCase {

                if predicate(eCase) {
                    return eCase
                }
            }
        } while enumCase != nil
        return nil
    }
}

var enumIndex: Int = -1
var enumCase: IterateEnum?

// Iterate until item returns nil
repeat {
    enumIndex += 1
    enumCase = IterateEnum.item(index: enumIndex)
    if let eCase = enumCase {
        print("The number \(eCase) in french: \(eCase.value.french), spanish: \(eCase.value.spanish), japanese: \(eCase.value.japanese)")
    }
} while enumCase != nil

print("Total of \(enumIndex) cases")

let number = IterateEnum.numberFromSpanish(number: "siete")

print("siete in japanese: \((number?.value.japanese ?? "Unknown"))")

This is the output:

The number Zero in french: zéro, spanish: cero, japanese: nuru
The number One in french: un, spanish: uno, japanese: ichi
The number Two in french: deux, spanish: dos, japanese: ni
The number Three in french: trois, spanish: tres, japanese: san
The number Four in french: quatre, spanish: cuatro, japanese: shi
The number Five in french: cinq, spanish: cinco, japanese: go
The number Six in french: six, spanish: seis, japanese: roku
The number Seven in french: sept, spanish: siete, japanese: shichi

Total of 8 cases

siete in japanese: shichi

UPDATE

I recently created a protocol to handle the enumeration. The protocol requires an enum with an Int raw value:

protocol EnumIteration {

    //Used to iterate enum or otherwise access enum case by index order. Iterate by looping until it returns nil

    static func item(index:Int) -> Self?
    static func iterate(item:((index:Int, enumCase:Self)->()), completion:(()->())?) {
    static func findItem(predicate:((enumCase:Self)->Bool)) -> Self?
    static func count() -> Int
}

extension EnumIteration where Self: RawRepresentable, Self.RawValue == Int {

    //Used to iterate enum or otherwise access enum case by index order. Iterate by looping until it returns nil
    static func item(index:Int) -> Self? {
        return Self.init(rawValue: index)
    }

    static func iterate(item:((index:Int, enumCase:Self)->()), completion:(()->())?) {

        var enumIndex:Int = -1
        var enumCase:Self?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = Self.item(enumIndex)

            if let eCase = enumCase {
                item(index: enumIndex, enumCase: eCase)
            }
        } while enumCase != nil
        completion?()
    }

    static func findItem(predicate:((enumCase:Self)->Bool)) -> Self? {

        var enumIndex:Int = -1
        var enumCase:Self?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = Self.item(enumIndex)

            if let eCase = enumCase {

                if predicate(enumCase:eCase) {
                    return eCase
                }
            }
        } while enumCase != nil
        return nil
    }

    static func count() -> Int {
        var enumIndex:Int = -1
        var enumCase:Self?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = Self.item(enumIndex)
        } while enumCase != nil

        //last enumIndex (when enumCase == nil) is equal to the enum count
        return enumIndex
    }
}

btnTest_Click(null, null);

Provided that the method isn't using either of these parameters (it's very common not to.)

To be honest though this is icky. If you have code that needs to be called you should follow the following convention:

protected void btnTest_Click(object sender, EventArgs e)
{
   SomeSub();
}

protected void SomeOtherFunctionThatNeedsToCallTheCode()
{
   SomeSub();
}

protected void SomeSub()
{
   // ...
}

Below are three functions you can use to alter and use the MS Access 2010 Import Specification. The third sub changes the name of an existing import specification. The second sub allows you to change any xml text in the import spec. This is useful if you need to change column names, data types, add columns, change the import file location, etc.. In essence anything you want modify for an existing spec. The first Sub is a routine that allows you to call an existing import spec, modify it for a specific file you are attempting to import, importing that file, and then deleting the modified spec, keeping the import spec "template" unaltered and intact. Enjoy.

Please also see this Microsoft Connect report on essentially, how blummin' difficult it is to use PowerShell to run shell commands (oh, the irony).

http://connect.microsoft.com/PowerShell/feedback/details/376207/

They suggest using --% as a way to force PowerShell to stop trying to interpret the text to the right.

For example:

MSBuild /t:Publish --% /p:TargetDatabaseName="MyDatabase";TargetConnectionString="Data Source=.\;Integrated Security=True" /p:SqlPublishProfilePath="Deploy.publish.xml" Database.sqlproj

If you have an existing list and you want to loop over it and keep track of the indices you can use the enumerate function. For example

l = ["apple", "pear", "banana"]
for i, fruit in enumerate(l):
   print "index", i, "is", fruit

For Asp.Net core you better use

<partial name="_MyPartialView" model="MyModel" />

So for example

@foreach (var item in Model)
{
   <partial name="_MyItemView" model="item" />
}

This is my favorite use of 112 and 114

select (convert(varchar, getdate(), 112)+ replace(convert(varchar, getdate(), 114),':','')) as 'Getdate() 

112 + 114 or YYYYMMDDHHMMSSMSS'

Result:

Getdate() 112 + 114 or YYYYMMDDHHMMSSMSS

Since the reduce method has been removed from the built in function from Python3, don't forget to import the functools in your code. Please look at the code snippet below.

import functools
my_list = [10,15,20,25,35]
sum_numbers = functools.reduce(lambda x ,y : x+y , my_list)
print(sum_numbers)

#include <ctime>
#include <functional>

using namespace std;

void f() {
  clock_t begin = clock();

  // ...code to measure time...

  clock_t end = clock();

  function<double(double, double)> convtime = [](clock_t begin, clock_t end)
  {
     return double(end - begin) / CLOCKS_PER_SEC;
  };

  printf("Elapsed time: %.2g sec\n", convtime(begin, end));

}

Similar example to one available here, only with additional conversion function + print out.

Yes You Can!

I worked on a project that did that (see comment). Unfortunately no code samples from that one, but googling revealed these:

How you can integrate data from several Web services using Excel and VBA

STEP BY STEP: Consuming Web Services through VBA (Excel or Word)

VBA: Consume Soap Web Services

I did this many years back on 2003 or possibly 97, yikes!

If I recall you need to use one of the subcommands above tied to a timer. You cannot operate on the db with any connections or forms open.

So you do something about closing all forms, and kick off the timer as the last running method. (which will in turn call the compact operation once everything closes)

If you haven't figured this out I could dig through my archives and pull it up.

If you are looking for a solution to your particular case, it would be:

Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse("2012-05-20T09:00:00.000Z");
String formattedDate = new SimpleDateFormat("dd/MM/yyyy, Ka").format(date);

You're currently writing the binary data in the string-object to your file. This binary data will probably only consist of a pointer to the actual data, and an integer representing the length of the string.

If you want to write to a text file, the best way to do this would probably be with an ofstream, an "out-file-stream". It behaves exactly like std::cout, but the output is written to a file.

The following example reads one string from stdin, and then writes this string to the file output.txt.

#include <fstream>
#include <string>
#include <iostream>

int main()
{
    std::string input;
    std::cin >> input;
    std::ofstream out("output.txt");
    out << input;
    out.close();
    return 0;
}

Note that out.close() isn't strictly neccessary here: the deconstructor of ofstream can handle this for us as soon as out goes out of scope.

For more information, see the C++-reference: http://cplusplus.com/reference/fstream/ofstream/ofstream/

Now if you need to write to a file in binary form, you should do this using the actual data in the string. The easiest way to acquire this data would be using string::c_str(). So you could use:

write.write( studentPassword.c_str(), sizeof(char)*studentPassword.size() );

If you are using a composite key in your bean, your parameter will be an object. You need to adjust your findBy method according to the new combination.

@Embeddable
public class CombinationId implements Serializable {

  private String xId;
  private String yId;
}

public class RealObject implements Serializable, Persistable<CombinationId> {

  @EmbeddedId private CombinationId id;
}

In that case, your repository findBy method should be as this

@Repository
public interface PaymentProfileRepository extends JpaRepository<RealObject, String> {

  List<RealObject> findById_XId(String someString);
}

The part you're missing is converting from the integer to the type-safe enum. Java will not do it automatically. There's a couple of ways you can go about this:

1. Use a list of static final ints rather than a type-safe enum and switch on the int value you receive (this is the pre-Java 5 approach)
2. Switch on either a specified id value (as described by heneryville) or the ordinal value of the enum values; i.e. guideView.GUIDE_VIEW_SEVEN_DAY.ordinal()

3. Determine the enum value represented by the int value and then switch on the enum value.

   enum GuideView {
       SEVEN_DAY,
       NOW_SHOWING,
       ALL_TIMESLOTS
   }
   
   // Working on the assumption that your int value is 
   // the ordinal value of the items in your enum
   public void onClick(DialogInterface dialog, int which) {
       // do your own bounds checking
       GuideView whichView = GuideView.values()[which];
       switch (whichView) {
           case SEVEN_DAY:
               ...
               break;
           case NOW_SHOWING:
               ...
               break;
       }
   }
   

   You may find it more helpful / less error prone to write a custom valueOf implementation that takes your integer values as an argument to resolve the appropriate enum value and lets you centralize your bounds checking.

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

If you want some icons (or all) from font-awesome including yout custom svg icons you can:

1- Go to http://fontawesome.io/ Download the zip and extract-it for example in your Desktop.

2- Go to http://fontastic.me/ use your email to create an account.

3- Once you have been logged-in click on the header option: Add More Icons.

4- Select the SVG of font-awesome located in your extracted zip inside fonts.

5- Repeat the procces uploading your own svg files.

6- Inside Home (at the header of the page) Select the icons you want to download, customize them to give your custom names and select publish to have a link or download the fonts and css.

Sorry about my english ! :D

Sybase IQ:

describe table_name;

mail -s "$(echo -e "This is the subject\nFrom: Paula <[email protected]>\n
Reply-to: [email protected]\nContent-Type: text/html\n")" 
[email protected] < htmlFileMessage.txt

the above is my solution..just replace the "Paula" with any name you want e.g Johny Bravo..any extra headers can be added just after the from and before the reply to...just make sure you know your headers syntax before adding them....this worked perfectly for me.

I think its worth referencing this similar answer: https://stackoverflow.com/a/5288804/64313

Here is a another quick solution. There are other variations possible on this using the <available> tag:

# exit with failure if no files are found
<property name="file" value="${some.path}/some.txt" />
<fail message="FILE NOT FOUND: ${file}">
    <condition><not>
        <available file="${file}" />
    </not></condition>
</fail>

You might want a variant of exists ... perldoc -f "-f"

      -X FILEHANDLE
       -X EXPR
       -X DIRHANDLE
       -X      A file test, where X is one of the letters listed below.  This unary operator takes one argument,
               either a filename, a filehandle, or a dirhandle, and tests the associated file to see if something is
               true about it.  If the argument is omitted, tests $_, except for "-t", which tests STDIN.  Unless
               otherwise documented, it returns 1 for true and '' for false, or the undefined value if the file
               doesn’t exist.  Despite the funny names, precedence is the same as any other named unary operator.
               The operator may be any of:

                   -r  File is readable by effective uid/gid.
                   -w  File is writable by effective uid/gid.
                   -x  File is executable by effective uid/gid.
                   -o  File is owned by effective uid.

                   -R  File is readable by real uid/gid.
                   -W  File is writable by real uid/gid.
                   -X  File is executable by real uid/gid.
                   -O  File is owned by real uid.

                   -e  File exists.
                   -z  File has zero size (is empty).
                   -s  File has nonzero size (returns size in bytes).

                   -f  File is a plain file.
                   -d  File is a directory.
                   -l  File is a symbolic link.
                   -p  File is a named pipe (FIFO), or Filehandle is a pipe.
                   -S  File is a socket.
                   -b  File is a block special file.
                   -c  File is a character special file.
                   -t  Filehandle is opened to a tty.

                   -u  File has setuid bit set.
                   -g  File has setgid bit set.
                   -k  File has sticky bit set.

                   -T  File is an ASCII text file (heuristic guess).
                   -B  File is a "binary" file (opposite of -T).

                   -M  Script start time minus file modification time, in days.

See that your __init__.py defines __all__. The modules - packages doc says

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.

...

The only solution is for the package author to provide an explicit index of the package. The import statement uses the following convention: if a package’s __init__.py code defines a list named __all__, it is taken to be the list of module names that should be imported when from package import * is encountered. It is up to the package author to keep this list up-to-date when a new version of the package is released. Package authors may also decide not to support it, if they don’t see a use for importing * from their package. For example, the file sounds/effects/__init__.py could contain the following code:

__all__ = ["echo", "surround", "reverse"]

This would mean that from sound.effects import * would import the three named submodules of the sound package.

I know this post is very old, For those who don't want to use android:fillViewport="true" because it sometimes doesn't bring up the edittext above keyboard. Use Relative layout instead of LinearLayout it solves the purpose.

You can do this using additional effects as a part of jQuery-ui

$('.show_hide').click(function () {
    $(".slidingDiv").toggle("slide");
});

I've been forgetting to share my solution, I couldn't find a way to do this without using JS. There are some corner cases where @Jeffery A Wooden's suggested CSS just wont cover.

This is what I apply to all of my UI containers, no need to apply to each element since it recuses on all the child elements.

CSS:

.unselectable {
    /* For Opera and <= IE9, we need to add unselectable="on" attribute onto each element */
    /* Check this site for more details: http://help.dottoro.com/lhwdpnva.php */
    -moz-user-select: none; /* These user-select properties are inheritable, used to prevent text selection */
    -webkit-user-select: none;
    -ms-user-select: none; /* From IE10 only */
    user-select: none; /* Not valid CSS yet, as of July 2012 */

    -webkit-user-drag: none; /* Prevents dragging of images/divs etc */
    user-drag: none;
}

JS:

var makeUnselectable = function( $target ) {
    $target
        .addClass( 'unselectable' ) // All these attributes are inheritable
        .attr( 'unselectable', 'on' ) // For IE9 - This property is not inherited, needs to be placed onto everything
        .attr( 'draggable', 'false' ) // For moz and webkit, although Firefox 16 ignores this when -moz-user-select: none; is set, it's like these properties are mutually exclusive, seems to be a bug.
        .on( 'dragstart', function() { return false; } );  // Needed since Firefox 16 seems to ingore the 'draggable' attribute we just applied above when '-moz-user-select: none' is applied to the CSS 

    $target // Apply non-inheritable properties to the child elements
        .find( '*' )
        .attr( 'draggable', 'false' )
        .attr( 'unselectable', 'on' ); 
};

This was way more complicated than it needed to be.

Its actually formulated more like:

https://<bucket-name>.s3.amazonaws.com/<key>

See here

If you are using JSP 2.0 and above It will come with the EL support: so that you can write in plain english and use and with empty operators to write your test:

<c:if test="${(empty object_1.attribute_A) and (empty object_2.attribute_B)}">

you can use CASE WHEN as follow as achieve the as IF ELSE.

SELECT FROM A a 
LEFT JOIN B b 
ON a.col1 = b.col1 
AND (CASE 
        WHEN a.col2 like '0%' then TRIM(LEADING '0' FROM a.col2)
        ELSE substring(a.col2,1,2)
    END
)=b.col2; 

p.s:just in case somebody needs this way.

If this is for a Windows Runtime application, then you have to add the self-signed certificate to the project and reference it in the appxmanifest.

The docs are here: http://msdn.microsoft.com/en-us/library/windows/apps/hh465031.aspx

Same thing if it's from a CA that's not trusted (like a private CA that the machine itself doesn't trust) -- you need to get the CA's public cert, add it as content to the app then add it to the manifest.

Once that's done, the app will see it as a correctly signed cert.

For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.

    Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);

If you want it to download and install from your own server then use the following code

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
    startActivity(intent);

public class MainClass {
   public static void main(String args[]) {
    System.out.printf("%d %(d %+d %05d\n", 3, -3, 3, 3);

    System.out.printf("Default floating-point format: %f\n", 1234567.123);
    System.out.printf("Floating-point with commas: %,f\n", 1234567.123);
    System.out.printf("Negative floating-point default: %,f\n", -1234567.123);
    System.out.printf("Negative floating-point option: %,(f\n", -1234567.123);

    System.out.printf("Line-up positive and negative values:\n");
    System.out.printf("% ,.2f\n% ,.2f\n", 1234567.123, -1234567.123);
  }
}

And print out:

3 (3) +3 00003
Default floating-point format: 1234567,123000
Floating-point with commas: 1.234.567,123000
Negative floating-point default: -1.234.567,123000
Negative floating-point option: (1.234.567,123000)

Line-up positive and negative values:
1.234.567,12
-1.234.567,12

Based on Jon Skeet answer i've made a class that permits to do it easily at work:

import com.google.common.collect.ImmutableMap;
import com.google.common.collect.Maps;

import java.util.EnumSet;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

/**
 * <p>
 * This permits to easily implement a failsafe implementation of the enums's valueOf
 * Better use it inside the enum so that only one of this object instance exist for each enum...
 * (a cache could solve this if needed)
 * </p>
 *
 * <p>
 * Basic usage exemple on an enum class called MyEnum:
 *
 *   private static final FailSafeValueOf<MyEnum> FAIL_SAFE = FailSafeValueOf.create(MyEnum.class);
 *   public static MyEnum failSafeValueOf(String enumName) {
 *       return FAIL_SAFE.valueOf(enumName);
 *   }
 *
 * </p>
 *
 * <p>
 * You can also use it outside of the enum this way:
 *   FailSafeValueOf.create(MyEnum.class).valueOf("EnumName");
 * </p>
 *
 * @author Sebastien Lorber <i>([email protected])</i>
 */
public class FailSafeValueOf<T extends Enum<T>> {

    private final Map<String,T> nameToEnumMap;

    private FailSafeValueOf(Class<T> enumClass) {
        Map<String,T> map = Maps.newHashMap();
        for ( T value : EnumSet.allOf(enumClass)) {
            map.put( value.name() , value);
        }
        nameToEnumMap = ImmutableMap.copyOf(map);
    }

    /**
     * Returns the value of the given enum element
     * If the 
     * @param enumName
     * @return
     */
    public T valueOf(String enumName) {
        return nameToEnumMap.get(enumName);
    }

    public static <U extends Enum<U>> FailSafeValueOf<U> create(Class<U> enumClass) {
        return new FailSafeValueOf<U>(enumClass);
    }

}

And the unit test:

import org.testng.annotations.Test;

import static org.testng.Assert.*;


/**
 * @author Sebastien Lorber <i>([email protected])</i>
 */
public class FailSafeValueOfTest {

    private enum MyEnum {
        TOTO,
        TATA,
        ;

        private static final FailSafeValueOf<MyEnum> FAIL_SAFE = FailSafeValueOf.create(MyEnum.class);
        public static MyEnum failSafeValueOf(String enumName) {
            return FAIL_SAFE.valueOf(enumName);
        }
    }

    @Test
    public void testInEnum() {
        assertNotNull( MyEnum.failSafeValueOf("TOTO") );
        assertNotNull( MyEnum.failSafeValueOf("TATA") );
        assertNull( MyEnum.failSafeValueOf("TITI") );
    }

    @Test
    public void testInApp() {
        assertNotNull( FailSafeValueOf.create(MyEnum.class).valueOf("TOTO") );
        assertNotNull( FailSafeValueOf.create(MyEnum.class).valueOf("TATA") );
        assertNull( FailSafeValueOf.create(MyEnum.class).valueOf("TITI") );
    }

}

Notice that i used Guava to make an ImmutableMap but actually you could use a normal map i think since the map is never returned...

Here is another way of doing this by using es6 template literals dynamically at runtime.

const str = 'My name is ${name} and my age is ${age}.'_x000D_
const obj = {name:'Simon', age:'33'}_x000D_
_x000D_
_x000D_
const result = new Function('const {' + Object.keys(obj).join(',') + '} = this.obj;return `' + str + '`').call({obj})_x000D_
_x000D_
document.body.innerHTML = result

It's easy

Get these tools:

1. dex2jar to translate dex files to jar files

2. jd-gui to view the java files in the jar

The source code is quite readable as dex2jar makes some optimizations.

Procedure:

And here's the procedure on how to decompile:

Step 1:

Convert classes.dex in test_apk-debug.apk to test_apk-debug_dex2jar.jar

d2j-dex2jar.sh -f -o output_jar.jar apk_to_decompile.apk
d2j-dex2jar.sh -f -o output_jar.jar dex_to_decompile.dex

Note 1: In the Windows machines all the .sh scripts are replaced by .bat scripts

Note 2: On linux/mac don't forget about sh or bash. The full command should be:

sh d2j-dex2jar.sh -f -o output_jar.jar apk_to_decompile.apk 

Note 3: Also, remember to add execute permission to dex2jar-X.X directory e.g. sudo chmod -R +x dex2jar-2.0

dex2jar documentation

Step 2:

Open the jar in JD-GUI

Here is another way:

• Browse someone's commit history (Click commits which is next to branch to see the whole commit history)

• Click the commit that with the person's username because there might be so many of them

• Then you should see the web address has a hash concatenated to the URL. Add .patch to this commit URL

• You will probably see the person's email address there

Example: https://github.com/[username]/[reponame]/commit/[hash].patch

You have several errors there.

First, you have to return a value from the function in the HTML markup: <form name="ff1" method="post" onsubmit="return validateForm();">

Second, in the JSFiddle, you place the code inside onLoad which and then the form won't recognize it - and last you have to return true from the function if all validation is a success - I fixed some issues in the update:

https://jsfiddle.net/mj68cq0b/

function validateURL(url) {
    var reurl = /^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/;
    return reurl.test(url);
}

function validateForm()
{
    // Validate URL
    var url = $("#frurl").val();
    if (validateURL(url)) { } else {
        alert("Please enter a valid URL, remember including http://");
        return false;
    }

    // Validate Title
    var title = $("#frtitle").val();
    if (title=="" || title==null) {
        alert("Please enter only alphanumeric values for your advertisement title");
        return false;
    }

    // Validate Email
    var email = $("#fremail").val();
    if ((/(.+)@(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email==null) { } else {
        alert("Please enter a valid email");
        return false;
    }
  return true;
}
