Issue resolved.!!! Below are the solutions.

For Java 6: Add below jars into {JAVA_HOME}/jre/lib/ext. 1. bcprov-ext-jdk15on-154.jar 2. bcprov-jdk15on-154.jar

Add property into {JAVA_HOME}/jre/lib/security/java.security security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider

Java 7:download jar from below link and add to {JAVA_HOME}/jre/lib/security http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

Java 8:download jar from below link and add to {JAVA_HOME}/jre/lib/security http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

Issue is that it is failed to decrypt 256 bits of encryption.

Task can be made simple javascript without jQuery etc.

<script type="text/javascript">
function showhide() {
document.getElementById("wizard").className = (document.getElementById("wizard").className=="swMain") ? swHide : swMain;
}
</script>

This function is simple if statement that looks if wizard has class swMain and change class to swHide and else if it's not swMain then change to swMain. This code doesn't support multiple class attributes but in this case it is just enough.

Now you have to make css class named swHide that has display: none

Then add on to the button onclick="showhide()"

So easy it is.

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Login();
    } 

    private static bool logOut;

    private static void Login()
    {
        LoginForm login = new LoginForm();
        MainForm main = new MainForm();
        main.FormClosed += new FormClosedEventHandler(main_FormClosed);
        if (login.ShowDialog(main) == DialogResult.OK)
        {
            Application.Run(main);
            if (logOut)
                Login();
        }
        else
            Application.Exit();
    }

    static void main_FormClosed(object sender, FormClosedEventArgs e)
    {
        logOut= (sender as MainForm).logOut;
    }
}

public partial class MainForm : Form
{
    private void btnLogout_ItemClick(object sender, ItemClickEventArgs e)
    {
        //timer1.Stop();
        this.logOut= true;
        this.Close();
    }
}

I had the same problem. I had to follow these steps to resolve the issue:

1. Make sure you have the following dependencies:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>

2. Create the following filter:

    public class CORSFilter extends OncePerRequestFilter {

        @Override
        protected void doFilterInternal(HttpServletRequest request,
                                        HttpServletResponse response, FilterChain filterChain)
                throws ServletException, IOException {

            String origin = request.getHeader("origin");
            origin = (origin == null || origin.equals("")) ? "null" : origin;
            response.addHeader("Access-Control-Allow-Origin", origin);
            response.addHeader("Access-Control-Allow-Methods", "POST, GET, PUT, UPDATE, DELETE, OPTIONS");
            response.addHeader("Access-Control-Allow-Credentials", "true");
            response.addHeader("Access-Control-Allow-Headers",
                    "Authorization, origin, content-type, accept, x-requested-with");

            filterChain.doFilter(request, response);
        }
    }

3. Apply the above filter for the requests in web.xml

    <filter>
        <filter-name>corsFilter</filter-name>
        <filter-class>com.your.package.CORSFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>corsFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

I hope this is useful to somebody.

This works for me:

? brew link --overwrite macvim
Linking /usr/local/Cellar/macvim/8.0-146_1... 12 symlinks created

default port of mysql is 3306

default pot of sql server is 1433

Please add the correct mime-types to your code - at least these ones:

.jpeg -> image/jpeg
.gif  -> image/gif
.png  -> image/png

A list of mime-types can be found here.

Furthermore, simplify the code's logic and report an error number to help the first level support track down problems:

$allowedExts = array(
  "pdf", 
  "doc", 
  "docx"
); 

$allowedMimeTypes = array( 
  'application/msword',
  'text/pdf',
  'image/gif',
  'image/jpeg',
  'image/png'
);

$extension = end(explode(".", $_FILES["file"]["name"]));

if ( 20000 < $_FILES["file"]["size"]  ) {
  die( 'Please provide a smaller file [E/1].' );
}

if ( ! ( in_array($extension, $allowedExts ) ) ) {
  die('Please provide another file type [E/2].');
}

if ( in_array( $_FILES["file"]["type"], $allowedMimeTypes ) ) 
{      
 move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); 
}
else
{
die('Please provide another file type [E/3].');
}

You could use hashname.key(valuename)

Or, an inversion may be in order. new_hash = hashname.invert will give you a new_hash that lets you do things more traditionally.

I know this question is over 6 years old, but still, I would like to share my method using tables and this won't require any CSS.

<table><tr><td><img src="loading.gif"></td><td> Loading...</td></tr></table>

Cheers! Happy Coding

There's a method for that in ActiveSupport v4.2.0. It's called transform_values and basically just executes a block for each key-value-pair.

Since they're doing it with a each I think there's no better way than to loop through.

hash = {sample: 'gach'}

result = {}
hash.each do |key, value|
  result[key] = do_stuff(value)
end

Update:

Since Ruby 2.4.0 you can natively use #transform_values and #transform_values!.

The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

from django.contrib.auth.models import User
user = User.objects.create_user(username='john',
                                 email='[email protected]',
                                 password='glass onion')

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

I haven't tried specifically getting the VM settings, but there is a wealth of information in the JMX utilities specifically the MXBean utilities. This would be where I would start. Hopefully you find something there to help you.

The sun website has a bunch on the technology:

As drew_w said, you can find a good example here.

I am having problems with stdin/stout - when payload size exceeds several kilobytes it hangs. I need to call Python functions not only with some short arguments, but with a custom payload that could be big.

A while ago, I wrote a virtual actor library that allows to distribute task on different machines via Redis. To call Python code, I added functionality to listen for messages from Python, process them and return results back to .NET. Here is a brief description of how it works.

It works on a single machine as well, but requires a Redis instance. Redis adds some reliability guarantees - payload is stored until a worked acknowledges completion. If a worked dies, the payload is returned to a job queue and then is reprocessed by another worker.

This method would work for a list implementation and could be implemented as an extension method.

public void TestMethod()
{
    var first = new List<int> {1, 2, 3, 4, 5};
    var second = new List<string> {"One", "Two", "Three", "Four", "Five"};

    foreach(var value in this.Zip(first, second, (x, y) => new {Number = x, Text = y}))
    {
        Console.WriteLine("{0} - {1}",value.Number, value.Text);
    }
}

public IEnumerable<TResult> Zip<TFirst, TSecond, TResult>(List<TFirst> first, List<TSecond> second, Func<TFirst, TSecond, TResult> selector)
{
    if (first.Count != second.Count)
        throw new Exception();  

    for(var i = 0; i < first.Count; i++)
    {
        yield return selector.Invoke(first[i], second[i]);
    }
}

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

Roughly the same kinds of things you've done in C#. Calling getch() is probably the simplest.

Your session status are set once you start a session, and by default, take the current GLOBAL value.

If you disconnected after you did SET @@GLOBAL.wait_timeout=300, then subsequently reconnected, you'd see

SHOW SESSION VARIABLES LIKE "%wait%";

Result: 300

Similarly, at any time, if you did

mysql> SET session wait_timeout=300;

You'd get

mysql> SHOW SESSION VARIABLES LIKE 'wait_timeout';

+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| wait_timeout  | 300   |
+---------------+-------+

Agreed with Yuri Tkachenko's answer.

I wanna point this out.

It's a pretty specific scenario. BUT it happens.

When you copy a gif before its loaded fully in some site like google images. it just gives the preview image address of that gif. Which is clearly not a gif.

So, make sure it ends with .gif extension

You can use the maps library to do this. Specifically, maps.FrozenMap

import maps
fm = maps.FrozenMap(my_dict)
hash(fm)

To install maps, just do:

pip install maps

It handles the nested dict case too:

import maps
fm = maps.FrozenMap.recurse(my_dict)
hash(fm)

Disclaimer: I am the author of the maps library.

Lots of others have already advised you to rethink your code to make it more testable - good advice and usually simpler than what I'm about to suggest.

If you can't change the code to make it more testable, PowerMock: https://code.google.com/p/powermock/

PowerMock extends Mockito (so you don't have to learn a new mock framework), providing additional functionality. This includes the ability to have a constructor return a mock. Powerful, but a little complicated - so use it judiciously.

You use a different Mock runner. And you need to prepare the class that is going to invoke the constructor. (Note that this is a common gotcha - prepare the class that calls the constructor, not the constructed class)

@RunWith(PowerMockRunner.class)
@PrepareForTest({First.class})

Then in your test set-up, you can use the whenNew method to have the constructor return a mock

whenNew(Second.class).withAnyArguments().thenReturn(mock(Second.class));

You can compare two images using functions from PIL.

import Image
import ImageChops

im1 = Image.open("splash.png")
im2 = Image.open("splash2.png")

diff = ImageChops.difference(im2, im1)

The diff object is an image in which every pixel is the result of the subtraction of the color values of that pixel in the second image from the first image. Using the diff image you can do several things. The simplest one is the diff.getbbox() function. It will tell you the minimal rectangle that contains all the changes between your two images.

You can probably implement approximations of the other stuff mentioned here using functions from PIL as well.

Something like this should work:

sh -c 'cd /tmp && exec pwd'

You can also initialise it like this:

struct name sara = { "Sara", "Black" };

Since (as a special case) you're allowed to initialise char arrays from string constants.

Now, as for what a struct actually is - it's a compound type composed of other values. What sara actually looks like in memory is a block of 20 consecutive char values (which can be referred to using sara.first, followed by 0 or more padding bytes, followed by another block of 20 consecutive char values (which can be referred to using sara.last). All other instances of the struct name type are laid out in the same way.

In this case, it is very unlikely that there is any padding, so a struct name is just a block of 40 characters, for which you have a name for the first 20 and the last 20.

You can find out how big a block of memory a struct name takes using sizeof(struct name), and you can find out where within that block of memory each member of the structure is placed at using offsetof(struct name, first) and offsetof(struct name, last).

Add an additional div around all container divs you want the drop shadow to encapsulate. Add the classes drop-shadow and container to the additional div. The class .container will keep the fluidity. Use the class .drop-shadow (or whatever you like) to add the box-shadow property. Then target the .drop-shadow div and negate the unwanted styles .container adds--such as left & right padding.

Example: http://jsfiddle.net/SHLu4/2/

It'll be something like:

<div class="container drop-shadow">
    <div class="container">
        <div class="row">
            <div class="col-md-8">Main Area</div>
            <div class="col-md-4">Side Area</div>
        </div>
    </div>
</div>

And your CSS:

<style>
    .drop-shadow {
        -webkit-box-shadow: 0 0 5px 2px rgba(0, 0, 0, .5);
        box-shadow: 0 0 5px 2px rgba(0, 0, 0, .5);
    }
    .container.drop-shadow {
        padding-left:0;
        padding-right:0;
    }
</style>

public class Class1 {
private String extref="MY";

public String getExtref() {
    return extref;
}

public String setExtref(String extref) {
    return this.extref = extref;
}

public static void main(String[] args) {

    Class1 obj=new Class1();
    String value=obj.setExtref("AFF");
    int returnedValue=getMethod(value);     
    System.out.println(returnedValue);
}

/**
 * @param value
 * @return
 */
private static int getMethod(String value) {
      HashMap<Integer, String> hashmap1 = new HashMap<Integer, String>();
        hashmap1.put(1,"MY");
        hashmap1.put(2,"AFF");

        if (hashmap1.containsValue(value))
        {
            for (Map.Entry<Integer,String> e : hashmap1.entrySet()) {
                Integer key = e.getKey();
                Object value2 = e.getValue();
                if ((value2.toString()).equalsIgnoreCase(value))
                {
                    return key;
                }
            }
        }   
        return 0;

}
}

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

function URL() {
    location.href = 'http://your.url.here';
}

Do

apachectl -k graceful

Check this link for more information : http://www.electrictoolbox.com/article/apache/restart-apache/

Try mono:

http://www.go-mono.com/mono-downloads/download.html

This download works on all versions of Windows XP, 2003, Vista and Windows 7.

1. In PostgreSQL command-line interface after login, type the following command to connect with the desired database.

       \c [database_name]
   

Then you will see this message You are now connected to database "[database_name]"

2. Type the following command to list all the tables.

       \dt
   

Well, you have some options.

You could configure sudo to not prompt for a password. This is not recommended, due to the security risks.

You could write an expect script to read the password and supply it to sudo when required, but that's clunky and fragile.

I would recommend designing the script to run as root and drop its privileges whenever they're not needed. Simply have it sudo -u someotheruser command for the commands that don't require root.

(If they have to run specifically as the user invoking the script, then you could have the script save the uid and invoke a second script via sudo with the id as an argument, so it knows who to su to..)

Option 1: Using Windows PowerShell

Open the windows menu. Type: "PowerShell" and open the 'Windows PowerShell' command window.

Goto folder with desired files: e.g. cd "C:\house chores" Notice: address must incorporate quotes "" if there are spaces involved.

You can use 'dir' to see all the files in the folder. Using '|' will pipeline the output of 'dir' for the command that follows.

Notes: 'dir' is an alias of 'Get-ChildItem'. See: wiki: cmdlets. One can provide further functionality. e.g. 'dir -recurse' outputs all the files, folders and sub-folders.

What if I only want a range of files?

Instead of 'dir |' I can use:

dir | where-object -filterscript {($_.Name -ge 'DSC_20') -and ($_.Name -le 'DSC_31')} |

For batch-renaming with the directory name as a prefix:

dir | Rename-Item -NewName {$_.Directory.Name + " - " + $_.Name}

Option 2: Using Command Prompt

In the folder press shift+right-click : select 'open command-window here'

for %a in (*.*) do ren "%a" "prefix - %a"

If there are a lot of files, it might be good to add an '@echo off' command before this and an 'echo on' command at the end.

SDK developers prefer to define their own types using typedef. This allows changing underlying types only in one place, without changing all client code. It is important to follow this convention. DWORD is unlikely to be changed, but types like DWORD_PTR are different on different platforms, like Win32 and x64. So, if some function has DWORD parameter, use DWORD and not unsigned int, and your code will be compiled in all future windows headers versions.

What this message from the glibc dynamic linker actually means is that the library mentioned (/lib/libpam.so.0 in your case) doesn't have the VERDEF ELF section while the binary (authpam in your case) has some version definitions in VERNEED section for this library (presumably, libpam.so.0). You can easily see it with readelf, just look at .gnu.version_d and .gnu.version_r sections (or lack thereof).

So it's not a symbol version mismatch, because if the binary wanted to get some specific version via VERNEED and the library didn't provide it in its actual VERDEF, that would be a hard linker error and the binary wouldn't run at all (like this compared to this or that). It's that the binary wants some versions, but the library doesn't provide any information about its versions.

What does it mean in practice? Usually, exactly what is seen in this example — nothing, things just work ignoring versioning. Could things break? Of course, yes, so the other answers are correct in the fact that one should use the same libraries at runtime as the ones the binary was linked to at build time.

More information could be found in Ulrich Dreppers "ELF Symbol Versioning".

maydenec is correct (in my case...). The file was moved.

I even found this file:

C:\Program Files (x86)\Android\android-sdk\tools\adb_has_moved.txt

Which explained this issue.

Suggestions in this file:

1. Install "Android SDK Platform-tools".
2. Please also update your PATH environment variable to include the "platform-tools/" directory.

If you know how many rows there will be in total you can use the ROW_NUMBER() function. Here's an examble from MSDN (http://msdn.microsoft.com/en-us/library/ms186734.aspx)

USE AdventureWorks;
GO
WITH OrderedOrders AS
(
    SELECT SalesOrderID, OrderDate,
    ROW_NUMBER() OVER (ORDER BY OrderDate) AS 'RowNumber'
    FROM Sales.SalesOrderHeader 
) 
SELECT * 
FROM OrderedOrders 
WHERE RowNumber BETWEEN 50 AND 60;

If you don't feel like aliassing you can also just prefix the tablenames.

This way you can better automate generation of your queries. Also, it's a best-practice to not use select * (it is obviously slower than just selecting the fields you need Furthermore, only explicitly name the fields you want to have.

Go to mirror.olnevhost.net/pub/apache/maven/binaries/ and check what is the latest tar.gz file

Supposing it is e.g. apache-maven-3.2.1-bin.tar.gz, from the command line; you should be able to simply do:

wget http://mirror.olnevhost.net/pub/apache/maven/binaries/apache-maven-3.2.1-bin.tar.gz

And then proceed to install it.

UPDATE: Adding complete instructions (copied from the comment below)

1. Run command above from the dir you want to extract maven to (e.g. /usr/local/apache-maven)

2. run the following to extract the tar:

   tar xvf apache-maven-3.2.1-bin.tar.gz
   

3. Next add the env varibles such as

   export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1

   export M2=$M2_HOME/bin

   export PATH=$M2:$PATH

4. Verify

   mvn -version
   

You might want to try out Quick JUnit: https://marketplace.eclipse.org/content/quick-junit

The plugin is stable and it allows switching between production and test code. I am currently using Eclipse Mars 4.5 and the plugin is supported for this release as well as for the following:

Luna (4.4), Kepler (4.3), Juno (4.2, 3.8), Previous to Juno (<=4.1)

You can use .append() for simply concatenating strings.

std::string s = "string1";
s.append("string2");

I think you might even be able to do:

std::string s = "string1";
s += "string2";

As for the formatting operations of C#'s StringBuilder, I believe snprintf (or sprintf if you want to risk writing buggy code ;-) ) into a character array and convert back to a string is about the only option.

You can concat the data in this way:

InfoDF = pd.DataFrame()
tempDF = pd.DataFrame(rows,columns=['id','min_date'])

InfoDF = pd.concat([InfoDF,tempDF])

If there is XML file with 2 different tables then will:

LOAD XML LOCAL INFILE 'table1.xml' INTO TABLE table1 
LOAD XML LOCAL INFILE 'table1.xml' INTO TABLE table2

work

Python uses "Duck typing", i.e. if a variable kwaks like a duck, it must be a duck. In your case, you probably want it to be iterable, or you want to access the item at a certain index. You should just do this: i.e. use the object in for var: or var[idx] inside a try block, and if you get an exception it wasn't a duck...

Java supplies a way of doing this directly. If you don't want the dashes, they are easy to strip out. Just use uuid.replace("-", "")

import java.util.UUID;

public class randomStringGenerator {
    public static void main(String[] args) {
        System.out.println(generateString());
    }

    public static String generateString() {
        String uuid = UUID.randomUUID().toString();
        return "uuid = " + uuid;
    }
}

Output

uuid = 2d7428a6-b58c-4008-8575-f05549f16316

Instead of bar use self.bar or Foo.bar. Assigning to Foo.bar will create a static variable, and assigning to self.bar will create an instance variable.

The global variable should be declare in config/initializers directory

COLOURS = %w(white blue black red green)

The previous answers did not work for me.

I used this code. If you are using OSX make sure to use the correct format.

RewriteRule (.*) http://www.NEWDOMAIN.com/ [R=301,L]

To achieve this you would do something like:

n=L[0][0]
m=len(A)
for i in range(m):
    for j in range(m):
        if L[i][j]==n:
            //do some processing
        else:
            break;

The conversion in JAVA is quite simple but need some understanding. As explain in the JLS for integer operations:

If an integer operator other than a shift operator has at least one operand of type long, then the operation is carried out using 64-bit precision, and the result of the numerical operator is of type long. If the other operand is not long, it is first widened (§5.1.5) to type long by numeric promotion (§5.6).

And an example is always the best way to translate the JLS ;)

int + long -> long
int(1) + long(2) + int(3) -> long(1+2) + long(3)

Otherwise, the operation is carried out using 32-bit precision, and the result of the numerical operator is of type int. If either operand is not an int, it is first widened to type int by numeric promotion.

short + int -> int + int -> int

A small example using Eclipse to show that even an addition of two shorts will not be that easy :

short s = 1;
s = s + s; <- Compiling error

//possible loss of precision
//  required: short
//  found:    int

This will required a casting with a possible loss of precision.

The same is true for the floating point operators

If at least one of the operands to a numerical operator is of type double, then the operation is carried out using 64-bit floating-point arithmetic, and the result of the numerical operator is a value of type double. If the other operand is not a double, it is first widened (§5.1.5) to type double by numeric promotion (§5.6).

So the promotion is done on the float into double.

And the mix of both integer and floating value result in floating values as said

If at least one of the operands to a binary operator is of floating-point type, then the operation is a floating-point operation, even if the other is integral.

This is true for binary operators but not for "Assignment Operators" like +=

A simple working example is enough to prove this

int i = 1;
i += 1.5f;

The reason is that there is an implicit cast done here, this will be execute like

i = (int) i + 1.5f
i = (int) 2.5f
i = 2

As others have pointed out, the accepted answer does not return both x86 and x64 installs. Below is my solution for that. It creates a StringBuilder, appends the registry values to it (with formatting), and writes its output to a text file:

const string FORMAT = "{0,-100} {1,-20} {2,-30} {3,-8}\n";

private void LogInstalledSoftware()
{
    var line = string.Format(FORMAT, "DisplayName", "Version", "Publisher", "InstallDate");
    line += string.Format(FORMAT, "-----------", "-------", "---------", "-----------");
    var sb = new StringBuilder(line, 100000);
    ReadRegistryUninstall(ref sb, RegistryView.Registry32);
    sb.Append($"\n[64 bit section]\n\n{line}");
    ReadRegistryUninstall(ref sb, RegistryView.Registry64);
    File.WriteAllText(@"c:\temp\log.txt", sb.ToString());
}

   private static void ReadRegistryUninstall(ref StringBuilder sb, RegistryView view)
    {
        const string REGISTRY_KEY = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
        using var baseKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, view);
        using var subKey = baseKey.OpenSubKey(REGISTRY_KEY);
        foreach (string subkey_name in subKey.GetSubKeyNames())
        {
            using RegistryKey key = subKey.OpenSubKey(subkey_name);
            if (!string.IsNullOrEmpty(key.GetValue("DisplayName") as string))
            {
                var line = string.Format(FORMAT,
                    key.GetValue("DisplayName"),
                    key.GetValue("DisplayVersion"),
                    key.GetValue("Publisher"),
                    key.GetValue("InstallDate"));
                sb.Append(line);
            }
            key.Close();
        }
        subKey.Close();
        baseKey.Close();
    }

Depending on your Java class package name, you're probably 4 or 5 levels down the directory structure.

If your Java class package is, for example, com.stackoverflow.project, then your class is located at src/com/stackoverflow/project.

You can either move up the directory structure with multiple ../, or you can move the text file to the same package as your class. It would be easier to move the text file.

Update

With ES6, this is possible in exactly the manner you have described; a detailed description can be found in the documentation.

Old answer

Default parameters in JavaScript can be implemented in mainly two ways:

function myfunc(a, b)
{
    // use this if you specifically want to know if b was passed
    if (b === undefined) {
        // b was not passed
    }
    // use this if you know that a truthy value comparison will be enough
    if (b) {
        // b was passed and has truthy value
    } else {
        // b was not passed or has falsy value
    }
    // use this to set b to a default value (using truthy comparison)
    b = b || "default value";
}

The expression b || "default value" evaluates the value AND existence of b and returns the value of "default value" if b either doesn't exist or is falsy.

Alternative declaration:

function myfunc(a)
{
    var b;

    // use this to determine whether b was passed or not
    if (arguments.length == 1) {
        // b was not passed
    } else {
        b = arguments[1]; // take second argument
    }
}

The special "array" arguments is available inside the function; it contains all the arguments, starting from index 0 to N - 1 (where N is the number of arguments passed).

This is typically used to support an unknown number of optional parameters (of the same type); however, stating the expected arguments is preferred!

Further considerations

Although undefined is not writable since ES5, some browsers are known to not enforce this. There are two alternatives you could use if you're worried about this:

b === void 0;
typeof b === 'undefined'; // also works for undeclared variables

Navicat15: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'

Ubuntu16.04, if mysql server is running and the configure in /etc/mysql like this:

[mysqld] socket = /var/run/mysqld/mysqld.sock

Then Navicat15 localhost default setting is: "/var/lib/mysql/mysql.sock"

You can edit in addvance like this:

I think this is the culprit:

cmd = new SqlCommand(query, con);

DataTable dt = Select(query);

cmd.ExecuteNonQuery();

ddtype.DataSource = dt;

I don't know what that code is supposed to do, but it looks like you want to create an SqlDataReader for that, as explained here and all over the web if you search for "SqlCommand DropDownList DataSource":

cmd = new SqlCommand(query, con);
ddtype.DataSource = cmd.ExecuteReader();

Or you can create a DataTable as explained here:

cmd = new SqlCommand(query, con);

SqlDataAdapter listQueryAdapter = new SqlDataAdapter(cmd);
DataTable listTable = new DataTable();
listQueryAdapter.Fill(listTable);

ddtype.DataSource = listTable;

The Java Service Wrapper might help you, depending on your requirements.

Since most for loops are very similar, Java provides a shortcut to reduce the amount of code required to write the loop called the for each loop.

Here is an example of the concise for each loop:

for (Integer grade : quizGrades){
      System.out.println(grade);
 }    

In the example above, the colon (:) can be read as "in". The for each loop altogether can be read as "for each Integer element (called grade) in quizGrades, print out the value of grade."

If you're using jQuery 1.5 you can use the new Deferreds pattern:

$('a.button').click(function(){
    if(condition == 'true'){
        $.when(function1()).then(function2());
    }
    else {
        doThis(someVariable);
    }
});

Edit: Updated blog link:

Rebecca Murphy had a great write-up on this here: http://rmurphey.com/blog/2010/12/25/deferreds-coming-to-jquery/

You can use the regular Switch widget and just call setTextOn() and setTextOff(), or use the android:textOn and android:textOff attributes.

And here's what it looks like:

Note that you can change the default encoding of the JVM using the confusingly-named property file.encoding.

If your application is particularly sensitive to encodings (perhaps through usage of APIs implying default encodings), then you should explicitly set this on JVM startup to a consistent (known) value.

Meteor is a framework built ontop of node.js. It uses node.js to deploy but has several differences.

The key being it uses its own packaging system instead of node's module based system. It makes it easy to make web applications using Node. Node can be used for a variety of things and on its own is terrible at serving up dynamic web content. Meteor's libraries make all of this easy.

Enhancement of Ben Brandt's answer to compensate even if the string starts with space by applying LTRIM(). Tried to edit his answer but rejected, so I am now posting it here separately.

DECLARE @test NVARCHAR(255)
SET @test = 'First Second'

SELECT SUBSTRING(LTRIM(@test),1,(CHARINDEX(' ',LTRIM(@test) + ' ')-1))

As far as I know '#error' only will print strings, in fact you don't even need to use quotes.

Have you tried writing various purposefully incorrect code using "BOOST_VERSION"? Perhaps something like "blah[BOOST_VERSION] = foo;" will tell you something like "string literal 1.2.1 cannot be used as an array address". It won't be a pretty error message, but at least it'll show you the relevant value. You can play around until you find a compile error that does tell you the value.

Just an addition to the answers above.

If you want to execute a SQL with an "IN" statement you could do this:

ids_list = [1,2,3]
query = "SELECT id, name FROM user WHERE id IN %s" 
args = [(ids_list,)] # Don't forget the "comma", to force the tuple
conn.execute(query, args)

Two points:

• There is no need for Parenthesis for the IN statement(like "... IN(%s) "), just put "...IN %s"
• Force the list of your ids to be one element of a tuple. Don't forget the " , " : (ids_list,)

EDIT Watch out that if the length of list is one or zero this will raise an error!

if (UIDevice.current.identifierForVendor?.uuidString) != nil

def mode(inp_list):
    sort_list = sorted(inp_list)
    dict1 = {}
    for i in sort_list:        
            count = sort_list.count(i)
            if i not in dict1.keys():
                dict1[i] = count

    maximum = 0 #no. of occurences
    max_key = -1 #element having the most occurences

    for key in dict1:
        if(dict1[key]>maximum):
            maximum = dict1[key]
            max_key = key 
        elif(dict1[key]==maximum):
            if(key<max_key):
                maximum = dict1[key]
                max_key = key

    return max_key

This seems to be very easy

I think the simple way is to use DateOffset from Pandas like so:

import pandas as pd
date_1 = pd.to_datetime("2013-03-31", format="%Y-%m-%d") - pd.DateOffset(months=1)

The result will be a Timestamp object

If you hadn't made any commit yet, only (1: branch) and (3: checkout) would be enough.
Or, in one command: git checkout -b newBranch

As mentioned in the git reset man page:

$ git branch topic/wip     # (1)
$ git reset --hard HEAD~3  # (2)  NOTE: use $git reset --soft HEAD~3 (explanation below)
$ git checkout topic/wip   # (3)

1. You have made some commits, but realize they were premature to be in the "master" branch. You want to continue polishing them in a topic branch, so create "topic/wip" branch off of the current HEAD.
2. Rewind the master branch to get rid of those three commits.
3. Switch to "topic/wip" branch and keep working.

Note: due to the "destructive" effect of a git reset --hard command (it does resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded), I would rather go with:

$ git reset --soft HEAD~3  # (2)

This would make sure I'm not losing any private file (not added to the index).
The --soft option won't touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do).

With Git 2.23+, the new command git switch would create the branch in one line (with the same kind of reset --hard, so beware of its effect):

git switch -f -c topic/wip HEAD~3

I also tried this app https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi

and it worked flawlessly.

If you combine both Ben and ausadmin's solutions, you end up with a very MVVM friendly solution:

<TextBox Text="{Binding Txt1, Mode=TwoWay, UpdateSourceTrigger=Explicit}">
    <TextBox.InputBindings>
        <KeyBinding Gesture="Enter" 
                    Command="{Binding UpdateTextBoxBindingOnEnterCommand}"
                    CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}" />
    </TextBox.InputBindings>
</TextBox>

...which means you are passing the TextBox itself as the parameter to the Command.

This leads to your Command looking like this (if you're using a DelegateCommand-style implementation in your VM):

    public bool CanExecuteUpdateTextBoxBindingOnEnterCommand(object parameter)
    {
        return true;
    }

    public void ExecuteUpdateTextBoxBindingOnEnterCommand(object parameter)
    {
        TextBox tBox = parameter as TextBox;
        if (tBox != null)
        {
            DependencyProperty prop = TextBox.TextProperty;
            BindingExpression binding = BindingOperations.GetBindingExpression(tBox, prop);
            if (binding != null) 
                binding.UpdateSource();
        }
    }

This Command implementation can be used for any TextBox and best of all no code in the code-behind though you may want to put this in it's own class so there are no dependencies on System.Windows.Controls in your VM. It depends on how strict your code guidelines are.

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

For beginners above answer might be difficult, this is the easiest way to understand it:

Traits

trait SayWorld {
    public function sayHello() {
        echo 'World!';
    }
}

so if you want to have sayHello function in other classes without re-creating the whole function you can use traits,

class MyClass{
  use SayWorld;

}

$o = new MyClass();
$o->sayHello();

Cool right!

Not only functions you can use anything in the trait(function, variables, const...). Also, you can use multiple traits: use SayWorld, AnotherTraits;

Interface

  interface SayWorld {
     public function sayHello();
  }

  class MyClass implements SayWorld { 
     public function sayHello() {
        echo 'World!';
     }
}

So this is how interfaces differ from traits: You have to re-create everything in the interface in an implemented class. Interfaces don't have an implementation and interfaces can only have functions and constants, it cannot have variables.

I hope this helps!

The Homebrew package manager includes launchctl plists to start automatically. For more information, run brew info postgres.

Start manually

pg_ctl -D /usr/local/var/postgres start

Stop manually

pg_ctl -D /usr/local/var/postgres stop

Start automatically

"To have launchd start postgresql now and restart at login:"

brew services start postgresql

What is the result of pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start?

What is the result of pg_ctl -D /usr/local/var/postgres status?

Are there any error messages in the server.log?

Make sure tcp localhost connections are enabled in pg_hba.conf:

# IPv4 local connections:
host    all    all    127.0.0.1/32    trust

Check the listen_addresses and port in postgresql.conf:

egrep 'listen|port' /usr/local/var/postgres/postgresql.conf

#listen_addresses = 'localhost'        # What IP address(es) to listen on;
#port = 5432                # (change requires restart)

Cleaning up

PostgreSQL was most likely installed via Homebrew, Fink, MacPorts or the EnterpriseDB installer.

Check the output of the following commands to determine which package manager it was installed with:

brew && brew list|grep postgres
fink && fink list|grep postgres
port && port installed|grep postgres

Simple just log into your GitHub account and on the far right side in the navigation menu choose Settings, in the Settings Tab choose Default Branch and return back to main page of your repository that did the trick for me.

not really. Server side code is happening on the server--- you can use javascript to display something to the user on the client side, but it obviously will only execute on the client side. This is the nature of a client server web technology. You're basically disconnected from the server when you get your response.

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

regarding the recommended answer's code,

For my bot the recommended answer did not work. This is because I'm using Chrome which is requiring me to use KEYEVENTF_SCANCODE in my dwFlags.

To get his code to work I had to modify these code blocks:

class KEYBDINPUT(ctypes.Structure):
    _fields_ = (("wVk",         wintypes.WORD),
                ("wScan",       wintypes.WORD),
                ("dwFlags",     wintypes.DWORD),
                ("time",        wintypes.DWORD),
                ("dwExtraInfo", wintypes.ULONG_PTR))

    def __init__(self, *args, **kwds):
        super(KEYBDINPUT, self).__init__(*args, **kwds)
        # some programs use the scan code even if KEYEVENTF_SCANCODE
        # isn't set in dwFflags, so attempt to map the correct code.
        #if not self.dwFlags & KEYEVENTF_UNICODE:l
            #self.wScan = user32.MapVirtualKeyExW(self.wVk,
                                                 #MAPVK_VK_TO_VSC, 0)
            # ^MAKE SURE YOU COMMENT/REMOVE THIS CODE^

def PressKey(keyCode):
    input = INPUT(type=INPUT_KEYBOARD,
              ki=KEYBDINPUT(wScan=keyCode,
                            dwFlags=KEYEVENTF_SCANCODE))
    user32.SendInput(1, ctypes.byref(input), ctypes.sizeof(input))

def ReleaseKey(keyCode):
    input = INPUT(type=INPUT_KEYBOARD,
              ki=KEYBDINPUT(wScan=keyCode,
                            dwFlags=KEYEVENTF_SCANCODE | KEYEVENTF_KEYUP))
    user32.SendInput(1, ctypes.byref(input), ctypes.sizeof(input))

time.sleep(5) # sleep to open browser tab
PressKey(0x26) # press right arrow key
time.sleep(2) # hold for 2 seconds
ReleaseKey(0x26) # release right arrow key

I hope this helps someone's headache!

Looks good to me. If the indexer was unsigned (uint etc), you might have to take that into account. Call me lazy, but in that (unsigned) case, I might just use a counter-variable:

uint pos = arr.Length;
for(uint i = 0; i < arr.Length ; i++)
{
    arr[--pos] = 42;
}

(actually, even here you'd need to be careful of cases like arr.Length = uint.MaxValue... maybe a != somewhere... of course, that is a very unlikely case!)

Based on some answers I found here, I made myself a small helper file to source for my projects:

trycatch.sh

#!/bin/bash

function try()
{
    [[ $- = *e* ]]; SAVED_OPT_E=$?
    set +e
}

function throw()
{
    exit $1
}

function catch()
{
    export ex_code=$?
    (( $SAVED_OPT_E )) && set +e
    return $ex_code
}

function throwErrors()
{
    set -e
}

function ignoreErrors()
{
    set +e
}

here is an example how it looks like in use:

#!/bin/bash
export AnException=100
export AnotherException=101

# start with a try
try
(   # open a subshell !!!
    echo "do something"
    [ someErrorCondition ] && throw $AnException

    echo "do something more"
    executeCommandThatMightFail || throw $AnotherException

    throwErrors # automaticatly end the try block, if command-result is non-null
    echo "now on to something completely different"
    executeCommandThatMightFail

    echo "it's a wonder we came so far"
    executeCommandThatFailsForSure || true # ignore a single failing command

    ignoreErrors # ignore failures of commands until further notice
    executeCommand1ThatFailsForSure
    local result = $(executeCommand2ThatFailsForSure)
    [ result != "expected error" ] && throw $AnException # ok, if it's not an expected error, we want to bail out!
    executeCommand3ThatFailsForSure

    echo "finished"
)
# directly after closing the subshell you need to connect a group to the catch using ||
catch || {
    # now you can handle
    case $ex_code in
        $AnException)
            echo "AnException was thrown"
        ;;
        $AnotherException)
            echo "AnotherException was thrown"
        ;;
        *)
            echo "An unexpected exception was thrown"
            throw $ex_code # you can rethrow the "exception" causing the script to exit if not caught
        ;;
    esac
}

Using the .EditedFormattedValue property solves the problem

To be notified each time a checkbox in a cell toggles a value when clicked, you can use the CellContentClick event and access the preliminary cell value .EditedFormattedValue.

As the event is fired the .EditedFormattedValue is not yet applied visually to the checkbox and not yet committed to the .Value property.

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
   var checkbox = dataGridView1.CurrentCell as DataGridViewCheckBoxCell;

   bool isChecked = (bool)checkbox.EditedFormattedValue;

}

The event fires on each Click and the .EditedFormattedValue toggles

It's not possible to clear the Serial Monitor window based on incoming serial data.

I can think of a couple of options, the simplest (and cheatiest) is to use println() with a fixed width string that you've generated that contains your sensor data.

The Arduino IDE's Serial Monitor's Autoscroll checkbox means if you persistently send the fixed width string (with 500ms delay perhaps) this will give the impression that it's updating once it gets to the bottom and starts scrolling. You could also shrink the height of the window to make it look like it only has one line.

To accomplish a fixed width string that's suitable for serial println() you'll need functions to convert your sensor values to strings, as well as pad/trim them to a persistent size. Then concatenate the values together (including separators if it makes the data easier to read)

An output of something similar to this is what i'm hinting at:

| 1.0 | 1.1 | 1.2 | 1.3 | 1.4 | 1.5 | 1.6 | 1.7 | 1.8 |

All things considered, this isn't a great solution but it would get you a result.

A far smarter idea is to build another program outside of Arduino and it's IDE that listens to the com port for sensor values sent from the Arduino. Your Arduino program will need to send a message your external program can unambiguously interpret, something like 1=0.5; where 1 = sensor ID and 0.5 = sensor value. The external program would then keep these values (1 for each sensor). The external program can then display this information in whatever way you'd like, a nice console output would be relatively easy to achieve :-)

C# has .NET's serialport class which is a pleasure to use. (most of the time!)

Python has a module called pyserial, which is also easy great.

Either language will give you much greater control over console output, should you choose to proceed this way.

To create a read-only database user account for MySQL

At a UNIX prompt, run the MySQL command-line program, and log in as an administrator by typing the following command:

mysql -u root -p

Type the password for the root account. At the mysql prompt, do one of the following steps:

To give the user access to the database from any host, type the following command:

grant select on database_name.* to 'read-only_user_name'@'%' identified by 'password';

If the collector will be installed on the same host as the database, type the following command:

grant select on database_name.* to 'read-only_user_name' identified by 'password';

This command gives the user read-only access to the database from the local host only. If you know the host name or IP address of the host that the collector is will be installed on, type the following command:

grant select on database_name.* to 'read-only_user_name'@'host_name or IP_address' identified by 'password';

The host name must be resolvable by DNS or by the local hosts file. At the mysql prompt, type the following command:

flush privileges;

Type quit.

The following is a list of example commands and confirmation messages:

mysql> grant select on dbname.* to 'readonlyuser'@'%' identified 
by 'pogo$23';
Query OK, 0 rows affected (0.11 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.

I don't understand why, over the course of eight years, no one has posted the easy answer. Rather than encode the file as base64, encode the json as a string. Then just decode the json on the server side.

In Javascript:

let formData = new FormData();
formData.append("file", myfile);
formData.append("myjson", JSON.stringify(myJsonObject));

POST it using Content-Type: multipart/form-data

On the server side, retrieve the file normally, and retrieve the json as a string. Convert the string to an object, which is usually one line of code no matter what programming language you use.

(Yes, it works great. Doing it in one of my apps.)

You can put your test specific properties into src/test/resources/config/application.properties.

The properties defined in this file will override those defined in src/main/resources/application.properties during testing.

For more information on why this works have a look at Spring Boots docs.

I had a similar issue with Windows server 2012, installing the feature "Application Server" in the server manager fixed the issue.

=IF(ISNA(INDEX(B:B,MATCH(C2,A:A,0))),"",INDEX(B:B,MATCH(C2,A:A,0)))

Will return the answer you want and also remove the #N/A result that would appear if you couldn't find a result due to it not appearing in your lookup list.

Ross

Calendar start = Calendar.getInstance();
Calendar end = Calendar.getInstance();
start.set(2010, 7, 23);
end.set(2010, 8, 26);
Date startDate = start.getTime();
Date endDate = end.getTime();
long startTime = startDate.getTime();
long endTime = endDate.getTime();
long diffTime = endTime - startTime;
long diffDays = diffTime / (1000 * 60 * 60 * 24);
DateFormat dateFormat = DateFormat.getDateInstance();
System.out.println("The difference between "+
  dateFormat.format(startDate)+" and "+
  dateFormat.format(endDate)+" is "+
  diffDays+" days.");

This will not work when crossing daylight savings time (or leap seconds) as orange80 pointed out and might as well not give the expected results when using different times of day. Using JodaTime might be easier for correct results, as the only correct way with plain Java before 8 I know is to use Calendar's add and before/after methods to check and adjust the calculation:

start.add(Calendar.DAY_OF_MONTH, (int)diffDays);
while (start.before(end)) {
    start.add(Calendar.DAY_OF_MONTH, 1);
    diffDays++;
}
while (start.after(end)) {
    start.add(Calendar.DAY_OF_MONTH, -1);
    diffDays--;
}

In the contracting world I'm often using machines that are using older images. After trying everything above I decided to update my VS 2013 to the most recent version (Update 4). After 90 minutes and a restart the references are working just fine now! Hope this helps!

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

sed can be put into multi-line search & replace mode to match newline characters \n.

To do so sed first has to read the entire file or string into the hold buffer ("hold space") so that it then can treat the file or string contents as a single line in "pattern space".

To replace a single newline portably (with respect to GNU and FreeBSD sed) you can use an escaped "real" newline.

# cf. http://austinmatzko.com/2008/04/26/sed-multi-line-search-and-replace/
echo 'California
Massachusetts
Arizona' | 
sed -n -e '
# if the first line copy the pattern to the hold buffer
1h
# if not the first line then append the pattern to the hold buffer
1!H
# if the last line then ...
$ {
# copy from the hold to the pattern buffer
g
# double newlines
s/\n/\
\
/g
s/$/\
/
p
}'

# output
# California
#
# Massachusetts
#
# Arizona
#

There is, however, a much more convenient was to achieve the same result:

echo 'California
Massachusetts
Arizona' | 
   sed G

I believe that is the point of an anonymous function, it lacks a name or a way to reference it.

If I were you I would just create a named function, or put it in a variable so you have a reference to it.

var t = {};
var handler = function(e) {
    t.scroll = function(x, y) {
        window.scrollBy(x, y);
    };
    t.scrollTo = function(x, y) {
        window.scrollTo(x, y);
    };
};
window.document.addEventListener("keydown", handler);

You can then remove it by

window.document.removeEventListener("keydown", handler);   

There is no notion of a function in the JDK as of java 6.

Guava has a Function interface though and the
Collections2.transform(Collection<E>, Function<E,E2>)
method provides the functionality you require.

Example:

// example, converts a collection of integers to their
// hexadecimal string representations
final Collection<Integer> input = Arrays.asList(10, 20, 30, 40, 50);
final Collection<String> output =
    Collections2.transform(input, new Function<Integer, String>(){

        @Override
        public String apply(final Integer input){
            return Integer.toHexString(input.intValue());
        }
    });
System.out.println(output);

Output:

[a, 14, 1e, 28, 32]

These days, with Java 8, there is actually a map function, so I'd probably write the code in a more concise way:

Collection<String> hex = input.stream()
                              .map(Integer::toHexString)
                              .collect(Collectors::toList);

Try this:

(add-hook 'text-mode-hook
  (function
   (lambda ()
     (setq tab-width 4)
     (define-key text-mode-map "\C-i" 'self-insert-command)
     )))

That will make TAB always insert a literal TAB character with tab stops every 4 characters (but only in Text mode). If that's not what you're asking for, please describe the behavior you'd like to see.

To get the variable name of var as a string:

var = 1000
var_name = [k for k,v in locals().items() if v == var][0] 
print(var_name) # ---> outputs 'var'

I have have this problem a number of times and there seems to be 2 ways of fixing it (shown below). You can use either of these properties to fix the rendering, or both at the same time.

Backface visibility hidden fixes the problem as it simplifies the animation to just the front of the object, whereas the default state is the front and the back.

backface-visibility: hidden;

TranslateZ also works as it is a hack to add hardware acceleration to the animation.

transform: translateZ(0);

Both of these properties fix the problem that you are having but some people also like to add

-webkit-font-smoothing: subpixel-antialiased;

to their animated to object. I find that it can change the rendering of a web font but feel free to experiment with that method too.

start MYSQL in safe mode

mysqld_safe --skip-grant-tables &

Connect to MYSQL server

mysql -u root

run SQL commands to reset password:

use mysql;
SET GLOBAL default_password_lifetime = 0;
SET PASSWORD = PASSWORD('new_password');

Last step, restart your mysql service

Also you could use like below in C++.

int j=3;
int i=2;
for (; i<n && j<n ; j=j+2, i=i+2){
  // your code
}

Its possible to make this even shorter with C# 6:

public string NullToString(string Value)
{
    return value?.ToString() ?? "";
}

$_SERVER['HTTP_HOST'] 

//to get the domain

$protocol=strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') === FALSE ? 'http' : 'https';
$domainLink=$protocol.'://'.$_SERVER['HTTP_HOST'];

//domain with protocol

$url=$protocol.'://'.$_SERVER['HTTP_HOST'].'?'.$_SERVER['QUERY_STRING'];

//protocol,domain,queryString total **As the $_SERVER['SERVER_NAME'] is not reliable for multi domain hosting!

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize and add following two methods:

public class SerilizeDeserialize
{

    // Serialize collection of any type to a byte stream

    public static byte[] Serialize<T>(T obj)
    {
        using (MemoryStream memStream = new MemoryStream())
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            binSerializer.Serialize(memStream, obj);
            return memStream.ToArray();
        }
    }

    // DSerialize collection of any type to a byte stream

    public static T Deserialize<T>(byte[] serializedObj)
    {
        T obj = default(T);
        using (MemoryStream memStream = new MemoryStream(serializedObj))
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            obj = (T)binSerializer.Deserialize(memStream);
        }
        return obj;
    }

}

How To use these method in your Class:

ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);

ArrayList arrayListMemDes = new ArrayList();

arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);

Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
    Console.WriteLine(item);
}

This mostly addresses the second line: best practices, assignments, function parameters etc.

General practice. Try to make everything const that you can. Or to put that another way, make everything const to begin with, and then remove exactly the minimum set of consts necessary to allow the program to function. This will be a big help in attaining const-correctness, and will help ensure that subtle bugs don't get introduced when people try and assign into things they're not supposed to modify.

Avoid const_cast<> like the plague. There are one or two legitimate use cases for it, but they are very few and far between. If you're trying to change a const object, you'll do a lot better to find whoever declared it const in the first pace and talk the matter over with them to reach a consensus as to what should happen.

Which leads very neatly into assignments. You can assign into something only if it is non-const. If you want to assign into something that is const, see above. Remember that in the declarations int const *foo; and int * const bar; different things are const - other answers here have covered that issue admirably, so I won't go into it.

Function parameters:

Pass by value: e.g. void func(int param) you don't care one way or the other at the calling site. The argument can be made that there are use cases for declaring the function as void func(int const param) but that has no effect on the caller, only on the function itself, in that whatever value is passed cannot be changed by the function during the call.

Pass by reference: e.g. void func(int &param) Now it does make a difference. As just declared func is allowed to change param, and any calling site should be ready to deal with the consequences. Changing the declaration to void func(int const &param) changes the contract, and guarantees that func can now not change param, meaning what is passed in is what will come back out. As other have noted this is very useful for cheaply passing a large object that you don't want to change. Passing a reference is a lot cheaper than passing a large object by value.

Pass by pointer: e.g. void func(int *param) and void func(int const *param) These two are pretty much synonymous with their reference counterparts, with the caveat that the called function now needs to check for nullptr unless some other contractual guarantee assures func that it will never receive a nullptr in param.

Opinion piece on that topic. Proving correctness in a case like this is hellishly difficult, it's just too damn easy to make a mistake. So don't take chances, and always check pointer parameters for nullptr. You will save yourself pain and suffering and hard to find bugs in the long term. And as for the cost of the check, it's dirt cheap, and in cases where the static analysis built into the compiler can manage it, the optimizer will elide it anyway. Turn on Link Time Code Generation for MSVC, or WOPR (I think) for GCC, and you'll get it program wide, i.e. even in function calls that cross a source code module boundary.

At the end of the day all of the above makes a very solid case to always prefer references to pointers. They're just safer all round.

This excerpt from the glibc manual 0.02 may also be relevant when researching the topic:

There is a potential problem with the size_t type and versions of GCC prior to release 2.4. ANSI C requires that size_t always be an unsigned type. For compatibility with existing systems' header files, GCC defines size_t in stddef.h' to be whatever type the system'ssys/types.h' defines it to be. Most Unix systems that define size_t in `sys/types.h', define it to be a signed type. Some code in the library depends on size_t being an unsigned type, and will not work correctly if it is signed.

The GNU C library code which expects size_t to be unsigned is correct. The definition of size_t as a signed type is incorrect. We plan that in version 2.4, GCC will always define size_t as an unsigned type, and the fixincludes' script will massage the system'ssys/types.h' so as not to conflict with this.

In the meantime, we work around this problem by telling GCC explicitly to use an unsigned type for size_t when compiling the GNU C library. `configure' will automatically detect what type GCC uses for size_t arrange to override it if necessary.

Per @EthanB suggestion and @karim making a back filled rectangle, I just created a category for the UIButton to achieve this.

Just drop in the Category code: https://github.com/zmonteca/UIButton-PLColor

Usage:

[button setBackgroundColor:uiTextColor forState:UIControlStateDisabled];

Optional forStates to use:

UIControlStateNormal
UIControlStateHighlighted
UIControlStateDisabled
UIControlStateSelected

1. For MySQL:

SELECT FIND_IN_SET(5, columnname) AS result 
FROM table

2.For Postgres SQL :

SELECT * 
FROM TABLENAME f
WHERE 'searchvalue' = ANY (string_to_array(COLUMNNAME, ','))

Example

select * 
from customer f
where '11' = ANY (string_to_array(customerids, ','))

IE10 does not support DX filters as IE9 and earlier have done, nor does it support a prefixed version of the greyscale filter.

However, you can use an SVG overlay in IE10 to accomplish the greyscaling. Example:

img.grayscale:hover {
    filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'1 0 0 0 0, 0 1 0 0 0, 0 0 1 0 0, 0 0 0 1 0\'/></filter></svg>#grayscale");
}

svg {
    background:url(http://4.bp.blogspot.com/-IzPWLqY4gJ0/T01CPzNb1KI/AAAAAAAACgA/_8uyj68QhFE/s400/a2cf7051-5952-4b39-aca3-4481976cb242.jpg);
}

You need to make the object first, then use [] to set it.

var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);

UPDATE 2018:

If you're able to use ES6 and Babel, you can use this new feature:

{
    [yourKeyVariable]: someValueArray,
}  

You need the get the values from the query string (since you dont have a method set, your using GET by default)

use the following tutorial.

http://papermashup.com/read-url-get-variables-withjavascript/

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        vars[key] = value;
    });
    return vars;
}

>>> import re
>>> st = " i think mabe 124 + <font color=\"black\"><font face=\"Times New Roman\">but I don't have a big experience it just how I see it in my eyes <font color=\"green\"><font face=\"Arial\">fun stuff"
>>> re.sub("<.*?>","",st)
" i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"
>>> 

Here is a working solution:

#include <stdio.h>
#include <string.h>

int main(int argc, char** argv) 
{
      char str1[16];
      char str2[16];
      strcpy(str1, "sssss");
      strcpy(str2, "kkkk");
      strcat(str1, str2);
      printf("%s", str1);
      return 0;
}

Output:

ssssskkkk

You have to allocate memory for your strings. In the above code, I declare str1 and str2 as character arrays containing 16 characters. I used strcpy to copy characters of string literals into them, and strcat to append the characters of str2 to the end of str1. Here is how these character arrays look like during the execution of the program:

After declaration (both are empty): 
str1: [][][][][][][][][][][][][][][][][][][][] 
str2: [][][][][][][][][][][][][][][][][][][][]

After calling strcpy (\0 is the string terminator zero byte): 
str1: [s][s][s][s][s][\0][][][][][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

After calling strcat: 
str1: [s][s][s][s][s][k][k][k][k][\0][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

I'm not sure about what you mean by "I have no access to image" But if you have access to parent div you can do the following:

Firs give id or class to your div:

<div class="parent">
   <img src="http://someimage.jpg">
</div>

Than add this to your css:

.parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 100%;
   width: 100%;
}

By default, Valgrind writes its output to stderr. So you need to do something like:

valgrind a.out > log.txt 2>&1

Alternatively, you can tell Valgrind to write somewhere else; see http://valgrind.org/docs/manual/manual-core.html#manual-core.comment (but I've never tried this).

Lots of good advince in the other posts. This is what I use:

Key key;
SecureRandom rand = new SecureRandom();
KeyGenerator generator = KeyGenerator.getInstance("AES");
generator.init(256, rand);
key = generator.generateKey();

If you need another randomness provider, which I sometime do for testing purposes, just replace rand with

MySecureRandom rand = new MySecureRandom();

To summarize, JSX doesn't support comments, either html-like or js-like:

<div>
    /* This will be rendered as text */
    // as well as this
    <!-- While this will cause compilation failure -->
</div>

and the only way to add comments "in" JSX is actually to escape into JS and comment in there:

<div>
    {/* This won't be rendered */}
    {// just be sure that your closing bracket is out of comment
    }
</div>

if you don't want to make some nonsense like

<div style={{display:'none'}}>
    actually, there are other stupid ways to add "comments"
    but cluttering your DOM is not a good idea
</div>

Finally, if you do want to create a comment node via React, you have to go much fancier, check out this answer.

I had this problem today, was in a lot of time crunch, so below idea worked:

• setTimeout with 1 sec -- call a function that shows the div
• setTimeout with 10 sec -- call a function that hides the div

Fade is not there, but that bootstrap feeling will be there.

Hope that helps.

For global use, you may use:

$val = $_REQUEST['subject'];

and to add yo your session, simply

session_start();
$_SESSION['subject'] =  $val;

And you dont need jQuery in this case.

thinking backwards

Take the last digits only (up to 10) ignoring first "1".

function formatUSNumber(entry = '') {
  const match = entry
    .replace(/\D+/g, '').replace(/^1/, '')
    .match(/([^\d]*\d[^\d]*){1,10}$/)[0]
  const part1 = match.length > 2 ? `(${match.substring(0,3)})` : match
  const part2 = match.length > 3 ? ` ${match.substring(3, 6)}` : ''
  const part3 = match.length > 6 ? `-${match.substring(6, 10)}` : ''    
  return `${part1}${part2}${part3}`
}

example input / output as you type

formatUSNumber('+1333')
// (333)

formatUSNumber('333')
// (333)

formatUSNumber('333444')
// (333) 444

formatUSNumber('3334445555')
// (333) 444-5555

It is possible to handle this using Vavr library

import static io.vavr.API.*;
import static io.vavr.Predicates.*;

Match(variable).of(
    Case($(isIn(5, 6, ... , 100)), () -> doSomething()),
    Case($(), () -> handleCatchAllCase())
);

This is of course only slight improvement since all cases still need to be listed explicitly. But it is easy to define custom predicate:

public static <T extends Comparable<T>> Predicate<T> isInRange(T lower, T upper) {
    return x -> x.compareTo(lower) >= 0 && x.compareTo(upper) <= 0;
}

Match(variable).of(
    Case($(isInRange(5, 100)), () -> doSomething()),
    Case($(), () -> handleCatchAllCase())
);

Match is an expression so here it returns something like Runnable instance instead of invoking methods directly. After match is performed Runnable can be executed.

For further details please see official documentation.

For those interested in the OS X solution for apps like Intelli-J where authorizations are stored by OSX:

1. Hit CMD+SPACE
2. Type "keychain"
3. Open keychain access
4. Under "Keychains" on the left, choose "login"
5. Under "Category" on the right, choose "All items"
6. At the top right in the search box, type in the the host URL (e.g. svn.mycompany.com)
7. Your keychain item will show if you chose to have your Mac remember your login credentials.
8. Double click the item and check the "Show password" checkbox at the bottom of the dialog that pops up. You will have to enter your Mac login to reveal the password.

Much easier than having to try to decrypt a password :-)

The user "geoand" is right in pointing out the reasons here and giving a solution. But a better approach is to encapsulate your configuration into a separate class, say SystemContiguration java class and then inject this class into what ever services you want to use those fields.

Your current way(@grahamrb) of reading config values directly into services is error prone and would cause refactoring headaches if config setting name is changed.

Like it has been written before:

• Right Click on Bash on Ubuntu on Windows Icon if you have it on a Task Bar Shortcut Icon
• Click on Properties
• Select Options Tab on the Properties Window
• Check the QuickEditMode option
• Click Apply

Now you are able to open a new Bash Terminal and just use Right-Click to paste

In order to be able to copy from Terminal, Just use CTRL+M and this will enable you to select and copy selected Text.

I fixed my problem by moving the <script type="text/javascript"></script> block containing the Sys.* calls lower down (to the last item before the close of the body's <asp:Content/> section) in the HTML on the page. I originally had my the script block in the HEAD <asp:Content/> section of my page. I was working inside a page that had a MasterPageFile. Hope this helps someone out.

You can try the expand option in Series.str.split('seperator', expand=True).
By default expand is False.

expand : bool, default False
Expand the splitted strings into separate columns.

• If True, return DataFrame/MultiIndex expanding dimensionality.
• If False, return Series/Index, containing lists of strings.

You need to use a global regular expression for this. Try it this way:

str.replace(/"/g, '\\"');

Check out regex syntax and options for the replace function in Using Regular Expressions with JavaScript.

Like this.

.divContainer input[type="text"] {
  width:150px;
}
.divContainer input[type="radio"] {
  width:20px;
}

Load a page within a page using an iframe. The following should serve as a good starting point.

<body>
  <div>
    <iframe src="page1.html" name="targetframe" allowTransparency="true" scrolling="no" frameborder="0" >
    </iframe>
  </div>

  <br/>

  <div>
    <a href="page2.html" target="targetframe">Link to Page 2</a><br />
    <a href="page3.html" target="targetframe">Link to Page 3</a>
  </div>
</body>

Django querysets are lazy. That means a query will hit the database only when you specifically ask for the result.

So until you print or actually use the result of a query you can filter further with no database access.

As you can see below your code only executes one sql query to fetch only the last 10 items.

In [19]: import logging                                 
In [20]: l = logging.getLogger('django.db.backends')    
In [21]: l.setLevel(logging.DEBUG)                      
In [22]: l.addHandler(logging.StreamHandler())      
In [23]: User.objects.all().order_by('-id')[:10]          
(0.000) SELECT "auth_user"."id", "auth_user"."username", "auth_user"."first_name", "auth_user"."last_name", "auth_user"."email", "auth_user"."password", "auth_user"."is_staff", "auth_user"."is_active", "auth_user"."is_superuser", "auth_user"."last_login", "auth_user"."date_joined" FROM "auth_user" ORDER BY "auth_user"."id" DESC LIMIT 10; args=()

mysqli is the enhanced version of mysql.

PDO extension defines a lightweight, consistent interface for accessing databases in PHP. Each database driver that implements the PDO interface can expose database-specific features as regular extension functions.

Do NOT loop through all cells!! There is a lot of overhead in communications between worksheets and VBA, for both reading and writing. Looping through all cells will be agonizingly slow. I'm talking hours.

Instead, load an entire sheet at once into a Variant array. In Excel 2003, this takes about 2 seconds (and 250 MB of RAM). Then you can loop through it in no time at all.

In Excel 2007 and later, sheets are about 1000 times larger (1048576 rows × 16384 columns = 17 billion cells, compared to 65536 rows × 256 columns = 17 million in Excel 2003). You will run into an "Out of memory" error if you try to load the whole sheet into a Variant; on my machine I can only load 32 million cells at once. So you have to limit yourself to the range you know has actual data in it, or load the sheet bit by bit, e.g. 30 columns at a time.

Option Explicit

Sub test()

    Dim varSheetA As Variant
    Dim varSheetB As Variant
    Dim strRangeToCheck As String
    Dim iRow As Long
    Dim iCol As Long

    strRangeToCheck = "A1:IV65536"
    ' If you know the data will only be in a smaller range, reduce the size of the ranges above.
    Debug.Print Now
    varSheetA = Worksheets("Sheet1").Range(strRangeToCheck)
    varSheetB = Worksheets("Sheet2").Range(strRangeToCheck) ' or whatever your other sheet is.
    Debug.Print Now

    For iRow = LBound(varSheetA, 1) To UBound(varSheetA, 1)
        For iCol = LBound(varSheetA, 2) To UBound(varSheetA, 2)
            If varSheetA(iRow, iCol) = varSheetB(iRow, iCol) Then
                ' Cells are identical.
                ' Do nothing.
            Else
                ' Cells are different.
                ' Code goes here for whatever it is you want to do.
            End If
        Next iCol
    Next iRow

End Sub

To compare to a sheet in a different workbook, open that workbook and get the sheet as follows:

Set wbkA = Workbooks.Open(filename:="C:\MyBook.xls")
Set varSheetA = wbkA.Worksheets("Sheet1") ' or whatever sheet you need

You can also remove rows and columns by feeding a vector of logical boolean values to the matrix. This handles the situation where you have multiple non-contiguous rows or non-contiguous columns that need to be deleted.

# TRUE = Keep a row/column
# FALSE = Delete a row/column
#
# FALSE for rows 4, 5, and 6
# Row:            1     2     3     4      5      6      7     8     9     10
rows_to_keep <- c(TRUE, TRUE, TRUE, FALSE, FALSE, FALSE, TRUE, TRUE, TRUE, TRUE)
    
# FALSE for columns 7, 8, and 9
# Column:         1     2     3     4     5     6     7      8      9      10
cols_to_keep <- c(TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, FALSE, FALSE, FALSE, TRUE) 

To remove just the rows:

t1 <- t1[rows_to_keep,]

To remove just the columns:

t1 <- t1[,cols_to_keep]

To remove both the rows and columns:

t1 <- t1[rows_to_keep, cols_to_keep]

This coding technique is useful if you don't know in advance what rows or columns you need to remove. The rows_to_keep and cols_to_keep vectors can be calculated as appropriate by your code.

This seems ok....

var b = list[y];
list[y] = list[x];
list[x] = b;

Howerver using

var b = list[y];

means a b variable is going to be to be present for the rest of the scope. This can potentially lead to a memory leak. Unlikely, but still better to avoid.

Maybe a good idea to put this into Array.prototype.swap

Array.prototype.swap = function (x,y) {
  var b = this[x];
  this[x] = this[y];
  this[y] = b;
  return this;
}

which can be called like:

list.swap( x, y )

This is a clean approach to both avoiding memory leaks and DRY.

svn log -r {2009-09-17}:HEAD

where 2009-09-17 is the date you went on holiday. To see the changed files as well as the summary, add a -v option:

svn log -r {2009-09-17}:HEAD -v

I haven't used WebSVN but there will be a log viewer somewhere that does the equivalent of these commands under the hood.

I was trying to connect mlab with my company wifi connection and it was giving this error. But when I switched to personal network it worked and got connected.

My solution handles quotes, overriding field and string separators, etc. It is short and sweet.

    public static string[] CSVRowToStringArray(string r, char fieldSep = ',', char stringSep = '\"')
    {
        bool bolQuote = false;
        StringBuilder bld = new StringBuilder();
        List<string> retAry = new List<string>();

        foreach (char c in r.ToCharArray())
            if ((c == fieldSep && !bolQuote))
            {
                retAry.Add(bld.ToString());
                bld.Clear();
            }
            else
                if (c == stringSep)
                    bolQuote = !bolQuote;
                else
                    bld.Append(c);

        return retAry.ToArray();
    }

Given it's a raw expression, you should use DB::raw() to set CURRENT_TIMESTAMP as a default value for a column:

$table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));

This works flawlessly on every database driver.

New shortcut

As of Laravel 5.1.25 (see PR 10962 and commit 15c487fe) you can use the new useCurrent() column modifier method to set the CURRENT_TIMESTAMP as a default value for a column:

$table->timestamp('created_at')->useCurrent();

Back to the question, on MySQL you could also use the ON UPDATE clause through DB::raw():

$table->timestamp('updated_at')->default(DB::raw('CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP'));

Gotchas

• MySQL
  
  Starting with MySQL 5.7, 0000-00-00 00:00:00 is no longer considered a valid date. As documented at the Laravel 5.2 upgrade guide, all timestamp columns should receive a valid default value when you insert records into your database. You may use the useCurrent() column modifier (from Laravel 5.1.25 and above) in your migrations to default the timestamp columns to the current timestamps, or you may make the timestamps nullable() to allow null values.

• PostgreSQL & Laravel 4.x
  
  In Laravel 4.x versions, the PostgreSQL driver was using the default database precision to store timestamp values. When using the CURRENT_TIMESTAMP function on a column with a default precision, PostgreSQL generates a timestamp with the higher precision available, thus generating a timestamp with a fractional second part - see this SQL fiddle.

  This will led Carbon to fail parsing a timestamp since it won't be expecting microseconds being stored. To avoid this unexpected behavior breaking your application you have to explicitly give a zero precision to the CURRENT_TIMESTAMP function as below:

  $table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP(0)'));
  

  Since Laravel 5.0, timestamp() columns has been changed to use a default precision of zero which avoids this.

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

An observable allows you to subscribe only whereas a subject allows you to both publish and subscribe.

So a subject allows your services to be used as both a publisher and a subscriber.

As of now, I'm not so good at Observable so I'll share only an example of Subject.

Let's understand better with an Angular CLI example. Run the below commands:

npm install -g @angular/cli

ng new angular2-subject

cd angular2-subject

ng serve

Replace the content of app.component.html with:

<div *ngIf="message">
  {{message}}
</div>

<app-home>
</app-home>

Run the command ng g c components/home to generate the home component. Replace the content of home.component.html with:

<input type="text" placeholder="Enter message" #message>
<button type="button" (click)="setMessage(message)" >Send message</button>

#message is the local variable here. Add a property message: string; to the app.component.ts's class.

Run this command ng g s service/message. This will generate a service at src\app\service\message.service.ts. Provide this service to the app.

Import Subject into MessageService. Add a subject too. The final code shall look like this:

import { Injectable } from '@angular/core';
import { Subject } from 'rxjs/Subject';

@Injectable()
export class MessageService {

  public message = new Subject<string>();

  setMessage(value: string) {
    this.message.next(value); //it is publishing this value to all the subscribers that have already subscribed to this message
  }
}

Now, inject this service in home.component.ts and pass an instance of it to the constructor. Do this for app.component.ts too. Use this service instance for passing the value of #message to the service function setMessage:

import { Component } from '@angular/core';
import { MessageService } from '../../service/message.service';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent {

  constructor(public messageService:MessageService) { }

  setMessage(event) {
    console.log(event.value);
    this.messageService.setMessage(event.value);
  }
}

Inside app.component.ts, subscribe and unsubscribe (to prevent memory leaks) to the Subject:

import { Component, OnDestroy } from '@angular/core';
import { MessageService } from './service/message.service';
import { Subscription } from 'rxjs/Subscription';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {

  message: string;
  subscription: Subscription;

  constructor(public messageService: MessageService) { }

  ngOnInit() {
    this.subscription = this.messageService.message.subscribe(
      (message) => {
        this.message = message;
      }
    );
  }

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

That's it.

Now, any value entered inside #message of home.component.html shall be printed to {{message}} inside app.component.html

My team ran into this problem when using Node with React Native and PouchDB. Here is how we solved it...

NPM install buffer:

$ npm install --save buffer

Ensure Buffer, btoa, and atob are loaded as a globals:

global.Buffer = global.Buffer || require('buffer').Buffer;

if (typeof btoa === 'undefined') {
  global.btoa = function (str) {
    return new Buffer(str, 'binary').toString('base64');
  };
}

if (typeof atob === 'undefined') {
  global.atob = function (b64Encoded) {
    return new Buffer(b64Encoded, 'base64').toString('binary');
  };
}

This question is rather old, but for those finding it, there's a new possible solution: Neovim contains a full-fledged, first-class terminal emulator, which does exactly what ConqueTerm tried to. Simply run :term <your command here>.

<C-\><C-n> will exit term mode back to normal-mode. If you're like me and prefer that escape still exit term mode, you can add this to your nvimrc:

tnoremap <ESC><ESC> <C-\><C-N>

And then hitting ESC twice will exit terminal mode back to normal-mode, so you can manipulate the buffer that the still-running command is writing to.

Though keep in mind, as nvim is under heavy development at the time I'm posting this answer, another way to exit terminal mode may be added. As Ctrl+\Ctrl+n switches to normal mode from almost any mode, I don't expect that this answer will become wrong, but be aware that if it doesn't work, this answer might be out of date.

This answer does not address the Debug button (you'd have to design a form and use the buttons on that to do something like the method in your next question). But it does address this part:

now I don't want to lose the comfortableness of the default handler which also point me to the exact line where the error has occured.

First, I'll assume you don't want this in production code - you want it either for debugging or for code you personally will be using. I use a compiler flag to indicate debugging; then if I'm troubleshooting a program, I can easily find the line that's causing the problem.

# Const IsDebug = True

Sub ProcA()
On Error Goto ErrorHandler
' Main code of proc

ExitHere:
    On Error Resume Next
    ' Close objects and stuff here
    Exit Sub

ErrorHandler:
    MsgBox Err.Number & ": " & Err.Description, , ThisWorkbook.Name & ": ProcA"
    #If IsDebug Then
        Stop            ' Used for troubleshooting - Then press F8 to step thru code 
        Resume          ' Resume will take you to the line that errored out
    #Else
        Resume ExitHere ' Exit procedure during normal running
    #End If
End Sub

Note: the exception to Resume is if the error occurs in a sub-procedure without an error handling routine, then Resume will take you to the line in this proc that called the sub-procedure with the error. But you can still step into and through the sub-procedure, using F8 until it errors out again. If the sub-procedure's too long to make even that tedious, then your sub-procedure should probably have its own error handling routine.

There are multiple ways to do this. Sometimes for smaller programs where I know I'm gonna be stepping through it anyway when troubleshooting, I just put these lines right after the MsgBox statement:

    Resume ExitHere         ' Normally exits during production
    Resume                  ' Never will get here
Exit Sub

It will never get to the Resume statement, unless you're stepping through and set it as the next line to be executed, either by dragging the next statement pointer to that line, or by pressing CtrlF9 with the cursor on that line.

Here's an article that expands on these concepts: Five tips for handling errors in VBA. Finally, if you're using VBA and haven't discovered Chip Pearson's awesome site yet, he has a page explaining Error Handling In VBA.

Unset display:

You can use the value unset which works in both Firefox and Chrome.

display: unset;

.foo     { display: none;  }
.foo.bar { display: unset; }

If you're designing for an iOS device or just webkit, you can do it with no JS whatsoever:

CSS:

@-webkit-keyframes spin {  
from {  
    -webkit-transform: rotate(0deg);  
}  
to {  
    -webkit-transform: rotate(360deg);  
    } 
}

.wheel {
    width:40px;
    height:40px;
    background:url(wheel.png);
    -webkit-animation-name: spin; 
    -webkit-animation-iteration-count: infinite; 
    -webkit-animation-timing-function: linear;
    -webkit-animation-duration: 3s; 
}

This would trigger the animation on load. If you wanted to trigger it on hover, it might look like this:

.wheel {
    width:40px;
    height:40px;
    background:url(wheel.png);
}

.wheel:hover {
    -webkit-animation-name: spin; 
    -webkit-animation-iteration-count: infinite; 
    -webkit-animation-timing-function: ease-in-out;
    -webkit-animation-duration: 3s; 
}

SELECT @LastChangeDate = GETDATE()

SOLUTION After all this time, I managed to resolve the problem.

In Module: UserForms(Name).Userform_Initialize

This method works best to dynamically init the current UserForm

DROP TABLE IF EXISTS [table_name]

it first checks if the table exists, if it does it deletes the table while

DROP TABLE [table_name]

it deletes without checking, so if it doesn't exist it exits with an error

Yes, but then what do you do about the django objects? simple json tends to choke on them.

If the objects are individual model objects (not querysets, e.g.), I have occasionally stored the model object type and the pk, like so:

seralized_dict = simplejson.dumps(my_dict, 
                     default=lambda a: "[%s,%s]" % (str(type(a)), a.pk)
                     )

to de-serialize, you can reconstruct the object referenced with model.objects.get(). This doesn't help if you are interested in the object details at the type the dict is stored, but it's effective if all you need to know is which object was involved.

If box-sizing is not an option, another way to do this is just to make it a child of the sized element.

Demo

CSS

.box {
  width: 100px;
  height: 100px;
  display: inline-block;
  margin-right: 5px;
}
.border {
  border: 1px solid;
  display: block;
}
.medium { border-width: 10px; }
.large  { border-width: 25px; }

HTML

<div class="box">
  <div class="border small">A</div>
</div>
<div class="box">
  <div class="border medium">B</div>
</div>
<div class="box">
  <div class="border large">C</div>
</div>

How I redirect to an area is add it as a parameter

@Html.Action("Action", "Controller", new { area = "AreaName" })

for the href portion of a link I use

@Url.Action("Action", "Controller", new { area = "AreaName" })

It should suffice to say whether bcrypt or SHA-512 (in the context of an appropriate algorithm like PBKDF2) is good enough. And the answer is yes, either algorithm is secure enough that a breach will occur through an implementation flaw, not cryptanalysis.

If you insist on knowing which is "better", SHA-512 has had in-depth reviews by NIST and others. It's good, but flaws have been recognized that, while not exploitable now, have led to the the SHA-3 competition for new hash algorithms. Also, keep in mind that the study of hash algorithms is "newer" than that of ciphers, and cryptographers are still learning about them.

Even though bcrypt as a whole hasn't had as much scrutiny as Blowfish itself, I believe that being based on a cipher with a well-understood structure gives it some inherent security that hash-based authentication lacks. Also, it is easier to use common GPUs as a tool for attacking SHA-2–based hashes; because of its memory requirements, optimizing bcrypt requires more specialized hardware like FPGA with some on-board RAM.

Note: bcrypt is an algorithm that uses Blowfish internally. It is not an encryption algorithm itself. It is used to irreversibly obscure passwords, just as hash functions are used to do a "one-way hash".

Cryptographic hash algorithms are designed to be impossible to reverse. In other words, given only the output of a hash function, it should take "forever" to find a message that will produce the same hash output. In fact, it should be computationally infeasible to find any two messages that produce the same hash value. Unlike a cipher, hash functions aren't parameterized with a key; the same input will always produce the same output.

If someone provides a password that hashes to the value stored in the password table, they are authenticated. In particular, because of the irreversibility of the hash function, it's assumed that the user isn't an attacker that got hold of the hash and reversed it to find a working password.

Now consider bcrypt. It uses Blowfish to encrypt a magic string, using a key "derived" from the password. Later, when a user enters a password, the key is derived again, and if the ciphertext produced by encrypting with that key matches the stored ciphertext, the user is authenticated. The ciphertext is stored in the "password" table, but the derived key is never stored.

In order to break the cryptography here, an attacker would have to recover the key from the ciphertext. This is called a "known-plaintext" attack, since the attack knows the magic string that has been encrypted, but not the key used. Blowfish has been studied extensively, and no attacks are yet known that would allow an attacker to find the key with a single known plaintext.

So, just like irreversible algorithms based cryptographic digests, bcrypt produces an irreversible output, from a password, salt, and cost factor. Its strength lies in Blowfish's resistance to known plaintext attacks, which is analogous to a "first pre-image attack" on a digest algorithm. Since it can be used in place of a hash algorithm to protect passwords, bcrypt is confusingly referred to as a "hash" algorithm itself.

Assuming that rainbow tables have been thwarted by proper use of salt, any truly irreversible function reduces the attacker to trial-and-error. And the rate that the attacker can make trials is determined by the speed of that irreversible "hash" algorithm. If a single iteration of a hash function is used, an attacker can make millions of trials per second using equipment that costs on the order of $1000, testing all passwords up to 8 characters long in a few months.

If however, the digest output is "fed back" thousands of times, it will take hundreds of years to test the same set of passwords on that hardware. Bcrypt achieves the same "key strengthening" effect by iterating inside its key derivation routine, and a proper hash-based method like PBKDF2 does the same thing; in this respect, the two methods are similar.

So, my recommendation of bcrypt stems from the assumptions 1) that a Blowfish has had a similar level of scrutiny as the SHA-2 family of hash functions, and 2) that cryptanalytic methods for ciphers are better developed than those for hash functions.

You can use a try-except

try:
   print(str.to.id)
except AttributeError: # Not a Retweet
   print('null')

Your Eclipse software suite doesn't support Java 1.8

Download a newer version of Eclipse.

I think you can use this code in order to have List of outgoing Addresses having a display Name (also different):

//1.The ACCOUNT
MailAddress fromAddress = new MailAddress("[email protected]", "my display name");
String fromPassword = "password";

//2.The Destination email Addresses
MailAddressCollection TO_addressList = new MailAddressCollection();

//3.Prepare the Destination email Addresses list
foreach (var curr_address in mailto.Split(new [] {";"}, StringSplitOptions.RemoveEmptyEntries))
{
    MailAddress mytoAddress = new MailAddress(curr_address, "Custom display name");
    TO_addressList.Add(mytoAddress);
}

//4.The Email Body Message
String body = bodymsg;

//5.Prepare GMAIL SMTP: with SSL on port 587
var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
    Timeout = 30000
};


//6.Complete the message and SEND the email:
using (var message = new MailMessage()
        {
            From = fromAddress,
            Subject = subject,
            Body = body,
        })
{
    message.To.Add(TO_addressList.ToString());
    smtp.Send(message);
}

I've found this solution by googling. I have just had this problem and it solved it.

My mistake was to put a project in other location out of the workspace, and share this workspace between several computers, where the paths difer. I learned that, when a project is out of workspace, its location is saved in workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location

Deleting .location and reimporting the project into workspace solved the issue. Hope this helps.

Assume you were:

1. Reading a network file and got disconnected.
2. Reading a local file that was no longer available.
3. Using some stream to read data and some other process closed the stream.
4. Trying to read/write a file, but don't have permission.
5. Trying to write to a file, but disk space was no longer available.

There are many more examples, but these are the most common, in my experience.

I would have thought this would have been answered already - but surely what you want is this: box-shadow: 0 0 3px #CC0000;

Example: http://jsfiddle.net/vmzLW/

The simple way to make the browser downloads a file is to make the request like that:

 function downloadFile(urlToSend) {
     var req = new XMLHttpRequest();
     req.open("GET", urlToSend, true);
     req.responseType = "blob";
     req.onload = function (event) {
         var blob = req.response;
         var fileName = req.getResponseHeader("fileName") //if you have the fileName header available
         var link=document.createElement('a');
         link.href=window.URL.createObjectURL(blob);
         link.download=fileName;
         link.click();
     };

     req.send();
 }

This opens the browser download pop up.

(I'm not allowed to comment yet.) I would suggest the following improvements to the already great answer of James McNellis:

template <typename Enumeration>
constexpr auto as_integer(Enumeration const value)
    -> typename std::underlying_type<Enumeration>::type
{
    static_assert(std::is_enum<Enumeration>::value, "parameter is not of type enum or enum class");
    return static_cast<typename std::underlying_type<Enumeration>::type>(value);
}

with

• constexpr: allowing me to use an enum member value as compile-time array size
• static_assert+is_enum: to 'ensure' compile-time that the function does sth. with enumerations only, as suggested

By the way I'm asking myself: Why should I ever use enum class when I would like to assign number values to my enum members?! Considering the conversion effort.

Perhaps I would then go back to ordinary enum as I suggested here: How to use enums as flags in C++?

Yet another (better) flavor of it without static_assert, based on a suggestion of @TobySpeight:

template <typename Enumeration>
constexpr std::enable_if_t<std::is_enum<Enumeration>::value,
std::underlying_type_t<Enumeration>> as_number(const Enumeration value)
{
    return static_cast<std::underlying_type_t<Enumeration>>(value);
}

Try Microsoft.VisualBasic.FileIO.FileSystem.MoveFile(Source, Destination, True). The last parameter is Overwrite switch, which System.IO.File.Move doesn't have.

Use Tkinter there are a ton of tutorials online for this. basically, you can create events. Here is a link to a great site! This makes it easy to capture clicks. Also, if you are trying to make a game, Tkinter also has a GUI. Although, I wouldn't recommend Python for games at all, it could be a fun experiment. Good Luck!

Array can only be used for specific types, whereas lists can be used for any object.

Arrays can also only data of one type, whereas a list can have entries of various object types.

Arrays are also more efficient for some numerical computation.

You should declare the variable in a header file:

extern int x;

and then define it in one C file:

int x;

In C, the difference between a definition and a declaration is that the definition reserves space for the variable, whereas the declaration merely introduces the variable into the symbol table (and will cause the linker to go looking for it when it comes to link time).

This issue still exists. An OnTouchListener with an OnSwipeTouchListener solves it in a simple way:

myView.setOnTouchListener(
    new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            if(!swipe.onTouch(v, event)) {
                if (event.getAction() == MotionEvent.ACTION_UP) {
                    // your code here

                    return true;
                } else if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    // your code here

                    return true;
                }
            }
            return false;
        }

    }
);

where swipe refers to a class which records whether swipe methods have been invoked, then forwards events to the delegate OnSwipeTouchListener.

private class DirtyOnSwipeTouchListener extends OnSwipeTouchListener {
    private boolean dirty = false;
    private OnSwipeTouchListener delegate;

    public DirtyOnSwipeTouchListener(Context ctx, OnSwipeTouchListener delegate) {
        super(ctx);

        this.delegate = delegate;
    }

    private void reset() {

To get the file name portion of the file name, the basename method is used:

var path = require("path");
var fileName = "C:\\Python27\\ArcGIS10.2\\python.exe";
var file = path.basename(fileName);

console.log(file); // 'python.exe'

If you want the file name without the extension, you can pass the extension variable (containing the extension name) to the basename method telling Node to return only the name without the extension:

var path = require("path");
var fileName = "C:\\Python27\\ArcGIS10.2\\python.exe";
var extension = path.extname(fileName);
var file = path.basename(fileName,extension);

console.log(file); // 'python'

You could use this plugin which creates a form, and submits it, then removes it from the page.

jQuery.download = function(url, data, method) {
    //url and data options required
    if (url && data) {
        //data can be string of parameters or array/object
        data = typeof data == 'string' ? data : jQuery.param(data);
        //split params into form inputs
        var inputs = '';
        jQuery.each(data.split('&'), function() {
            var pair = this.split('=');
            inputs += '<input type="hidden" name="' + pair[0] +
                '" value="' + pair[1] + '" />';
        });
        //send request
        jQuery('<form action="' + url +
                '" method="' + (method || 'post') + '">' + inputs + '</form>')
            .appendTo('body').submit().remove();
    };
};


$.download(
    '/export.php',
    'filename=mySpreadsheet&format=xls&content=' + spreadsheetData
);

This worked for me. Found this plugin here

Quite a painful problem for me too. Just spent about an hour trying to build and re-build - no joy. In the end I had to do this:

1. Upgrade the base SDK to the latest ( in my case iOS 5 )
2. Restart xCode
3. Clean & Build
4. It worked!

I guess it's a bunch of jargon about arm6 , arm7 as it looked like my project was valid for both, at least the settings seemed to say so ) , my guess is this is a cynical way to bamboozle us with the technicalities, which we don't understand, so we just take the easy option and target the latest iOS ( good for Apple with more people being up-to-date ) ....

Use the $@ variable, which expands to all command-line parameters separated by spaces.

abc "$@"

I'm sure you know that a std::vector<X> stores a whole bunch of X objects, right? But if you have a std::map<X, Y>, what it actually stores is a whole bunch of std::pair<const X, Y>s. That's exactly what a map is - it pairs together the keys and the associated values.

When you iterate over a std::map, you're iterating over all of these std::pairs. When you dereference one of these iterators, you get a std::pair containing the key and its associated value.

std::map<std::string, int> m = /* fill it */;
auto it = m.begin();

Here, if you now do *it, you will get the the std::pair for the first element in the map.

Now the type std::pair gives you access to its elements through two members: first and second. So if you have a std::pair<X, Y> called p, p.first is an X object and p.second is a Y object.

So now you know that dereferencing a std::map iterator gives you a std::pair, you can then access its elements with first and second. For example, (*it).first will give you the key and (*it).second will give you the value. These are equivalent to it->first and it->second.

For anyone hitting this issue in the future: the specific situation here ("the server isn't sending back the WSDL properly") may or may not always be relevant, but two key aspects should always be:

1. The message faultCode=INVALID_WSDL: Expected element '{http://schemas.xmlsoap.org/wsdl/}definitions' means that the actual content returned is not XML with a base element of "definitions" in the WSDL namespace.
2. The message WSDLException (at /html) tells you an important clue about what it did find — for this example, /html strongly implies that a normal webpage was returned, rather than a WSDL. Another common situation is seeing something like /soapenv:Reason, which would indicate that the server was trying to treat it as a SOAP call — for example, this can happen if your URL is for the "base" service URL rather than the WSDL.

Using .htaccess to Redirect to www or non-www:

Simply put the following lines of code into your main, root .htaccess file. In both cases, just change out domain.com to your own hostname.

Redirect to www

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_HOST} ^domain\.com [NC]
  RewriteRule ^(.*)$ http://wwwDOTdomainDOtcom/$1 [L,R=301]
</IfModule>

Redirect to non-www

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_HOST} ^www\.domain\.com [NC]
  RewriteRule ^(.*)$ http://domainDOTcom/$1 [L,R=301]
</IfModule>

change DOT to => . !!!

For those who have this problem with collection of enums here is how to solve it:

@Enumerated(EnumType.STRING)
@Column(name = "OPTION")
@CollectionTable(name = "MY_ENTITY_MY_OPTION")
@ElementCollection(targetClass = MyOptionEnum.class, fetch = EAGER)
Collection<MyOptionEnum> options;

The data you are encoding is a keyless array, so JSON encodes it with [] brackets. See www.json.org for more information about that. The curly braces are used for lists with key/value pairs.

From www.json.org:

JSON is built on two structures:

A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.

An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma).

An array is an ordered collection of values. An array begins with [ (left bracket) and ends with ] (right bracket). Values are separated by , (comma).

Add offset8 to your class, for example:

<div class="offset8">aligns to the right</div>

I would also recommend Ilmbase, which is part of OpenEXR. It's a good set of templated 2,3,4-vector and matrix routines.

If order does matter, how about:

>>> foo = 'mppmt'
>>> ''.join(sorted(set(foo), key=foo.index))
'mpt'

Since this is the first question from Google I'll add the JavaScript style typeof alternative here as well:

myObject.getClass().getName() // String

Use Shell "program file path file path you want to open".

Example:

Shell "c:\windows\system32\mspaint.exe c:users\admin\x.jpg"

for finding a specific value of a column you can use the code below

irrespective of the preference you can use the any of the method you like

df.col_name.value_counts().Value_you_are_looking_for

take example of the titanic dataset

df.Sex.value_counts().male

this gives a count of all male on the ship Although if you want to count a numerical data then you cannot use the above method because value_counts() is used only with series type of data hence fails So for that you can use the second method example

the second method is

#this is an example method of counting on a data frame
df[(df['Survived']==1)&(df['Sex']=='male')].counts()

this is not that efficient as value_counts() but surely will help if you want to count values of a data frame hope this helps

There is built-in command line debugger client within Node.js. Cloud 9 IDE have also pretty nice (visual) debugger.

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.

If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE

echo %WORKSPACE%

If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &, &&, or || are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.

setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
  set WORKSPACE=AFTER
  echo Normal Expansion = %WORKSPACE%
  echo Delayed Expansion = !WORKSPACE!
)

The output of the above is

Normal Expansion = BEFORE
Delayed Expansion = AFTER

Use HELP SET or SET /? from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.

It's a little unclear whether you're asking for opinions, eg. "it's common to do xxx" or an actual rule, so I'm going to lean in the direction of rules.

The examples you cite seem based upon the examples in the spec for the nav element. Remember that the spec keeps getting tweaked and the rules are sometimes convoluted, so I'd venture many people might tend to just do what's given rather than interpret. You're showing two separate examples with different behavior, so there's only so much you can read into it. Do either of those sites also have the opposing sub/nav situation, and if so how do they handle it?

Most importantly, though, there's nothing in the spec saying either is the way to do it. One of the goals with HTML5 was to be very clear[this for comparison] about semantics, requirements, etc. so the omission is worth noting. As far as I can see, the examples are independent of each other and equally valid within their own context of layout requirements, etc.

Having the nav's source position be conditional is kind of silly(another red flag). Just pick a method and go with it.
