If you store an object in session state, that object must be serializable.

http://www.hpenterprisesecurity.com/vulncat/en/vulncat/dotnet/asp_dotnet_bad_practices_non_serializable_object_stored_in_session.html

edit:

In order for the session to be serialized correctly, all objects the application stores as session attributes must declare the [Serializable] attribute. Additionally, if the object requires custom serialization methods, it must also implement the ISerializable interface.

In addition to other nice answers, a quote from Linux system programming written by Google's expert Robert Love:

Advantages of mmap( )

Manipulating files via mmap( ) has a handful of advantages over the standard read( ) and write( ) system calls. Among them are:

• Reading from and writing to a memory-mapped file avoids the extraneous copy that occurs when using the read( ) or write( ) system calls, where the data must be copied to and from a user-space buffer.

• Aside from any potential page faults, reading from and writing to a memory-mapped file does not incur any system call or context switch overhead. It is as simple as accessing memory.

• When multiple processes map the same object into memory, the data is shared among all the processes. Read-only and shared writable mappings are shared in their entirety; private writable mappings have their not-yet-COW (copy-on-write) pages shared.

• Seeking around the mapping involves trivial pointer manipulations. There is no need for the lseek( ) system call.

For these reasons, mmap( ) is a smart choice for many applications.

Disadvantages of mmap( )

There are a few points to keep in mind when using mmap( ):

• Memory mappings are always an integer number of pages in size. Thus, the difference between the size of the backing file and an integer number of pages is "wasted" as slack space. For small files, a significant percentage of the mapping may be wasted. For example, with 4 KB pages, a 7 byte mapping wastes 4,089 bytes.

• The memory mappings must fit into the process' address space. With a 32-bit address space, a very large number of various-sized mappings can result in fragmentation of the address space, making it hard to find large free contiguous regions. This problem, of course, is much less apparent with a 64-bit address space.

• There is overhead in creating and maintaining the memory mappings and associated data structures inside the kernel. This overhead is generally obviated by the elimination of the double copy mentioned in the previous section, particularly for larger and frequently accessed files.

For these reasons, the benefits of mmap( ) are most greatly realized when the mapped file is large (and thus any wasted space is a small percentage of the total mapping), or when the total size of the mapped file is evenly divisible by the page size (and thus there is no wasted space).

It is possible and is deceptively easy:

1. "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties ? Publish. This will create an installer for a ClickOnce application.
2. But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj).
3. Zip that folder (leave out any *.vhost.* files and the app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.

An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.

It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.

This is how I list all the groups (direct and indirect) for a specific Distinguished Name:

The string 1.2.840.113556.1.4.1941 specifies LDAP_MATCHING_RULE_IN_CHAIN.

This rule is limited to filters that apply to the DN. This is a special "extended" match operator that walks the chain of ancestry in objects all the way to the root until it finds a match.

This method is 25 times faster than the UserPrincipal.GetGroups() method in my testing.

Note: The primary group (typically Domain Users) is not returned by this or GetGroups() method. To get the primary group name too, I've confirmed this method works.

Additionally, I found this list of LDAP filters extremely useful.

private IEnumerable<string> GetGroupsForDistinguishedName(DirectoryEntry domainDirectoryEntry, string distinguishedName)
{
    var groups = new List<string>();
    if (!string.IsNullOrEmpty(distinguishedName))
    {
        var getGroupsFilterForDn = $"(&(objectCategory=group)(member:1.2.840.113556.1.4.1941:={distinguishedName}))";
        using (DirectorySearcher dirSearch = new DirectorySearcher(domainDirectoryEntry))
        {
            dirSearch.Filter = getGroupsFilterForDn;
            dirSearch.PropertiesToLoad.Add("name");

            using (var results = dirSearch.FindAll())
            {
                foreach (SearchResult result in results)
                {
                    if (result.Properties.Contains("name"))
                        groups.Add((string)result.Properties["name"][0]);
                }
            }
        }
    }

    return groups;
}

import numpy as np
arr_float = np.arange(10, dtype=np.float32)
arr_int = arr_float.view(np.float32)

use view() and parameter 'dtype' to change the array in place.

For WAMP [Windows 7 Ultimate x64-bit] Users:

I agree with what DangerDave said and so I'm making an answer available for WAMP Users.

Note: First of all, you have to go to your ..\WAMP\Bin\MySQL\MySQL[Your MySQL Version]\Data folder.

Now, you'll see folders of all your databases

• Double-click the folder of the database which has the offending table to open it
• There shouldn't be a file [Your offending MySQL table name].frm, instead there should be a file [Your offending MySQL table name].ibd
• Delete the [Your offending MySQL table name].ibd
• Then, delete it from the Recycle Bin too
• Then run your MySQL query on the database and you're done

On Linux, if you call this inside the git repository folder:

git config http.sslVerify false

this will add sslVerify = false in the [http] section of the config file in the .git folder, which can also be the solution, if you want to add this manually with nano .git/config:

...
[http]
  sslVerify = false

Basically you do the counts as sub-queries within a standard select.

An example would be the following, this returns 1 row, two columns

SELECT
 (SELECT COUNT(*) FROM MyTable WHERE MyCol = 'MyValue') AS MyTableCount,
 (SELECT COUNT(*) FROM YourTable WHERE MyCol = 'MyValue') AS YourTableCount,

javafx.scene.control.Alert

For a an in depth description of how to use JavaFX dialogs see: JavaFX Dialogs (official) by code.makery. They are much more powerful and flexible than Swing dialogs and capable of far more than just popping up messages.

import javafx.scene.control.Alert
import javafx.scene.control.Alert.AlertType;
import javafx.application.Platform;

public class ClassNameHere
{

    public static void infoBox(String infoMessage, String titleBar)
    {
        /* By specifying a null headerMessage String, we cause the dialog to
           not have a header */
        infoBox(infoMessage, titleBar, null);
    }

    public static void infoBox(String infoMessage, String titleBar, String headerMessage)
    {
        Alert alert = new Alert(AlertType.INFORMATION);
        alert.setTitle(titleBar);
        alert.setHeaderText(headerMessage);
        alert.setContentText(infoMessage);
        alert.showAndWait();
    }
}

One thing to keep in mind is that JavaFX is a single threaded GUI toolkit, which means this method should be called directly from the JavaFX application thread. If you have another thread doing work, which needs a dialog then see these SO Q&As: JavaFX2: Can I pause a background Task / Service? and Platform.Runlater and Task Javafx.

To use this method call:

ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE");

or

ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE", "HEADER MESSAGE");

this Works for me, all other solutions didn't.

func adjustUITextViewHeight(arg : UITextView)

    arg.translatesAutoresizingMaskIntoConstraints = true
    arg.sizeToFit()
    arg.scrollEnabled = false
}

In Swift 4 the syntax of arg.scrollEnabled = false has changed to arg.isScrollEnabled = false.

I hope you won't mind a slight tangent, but thought you may be interested to know that besides F (for float), D (for double), and L (for long), a proposal has been made to add suffixes for byte and short—Y and S respectively. This would eliminate to the need to cast to bytes when using literal syntax for byte (or short) arrays. Quoting the example from the proposal:

MAJOR BENEFIT: Why is the platform better if the proposal is adopted?

cruddy code like

 byte[] stuff = { 0x00, 0x7F, (byte)0x80,  (byte)0xFF};

can be recoded as

 byte[] ufum7 = { 0x00y, 0x7Fy, 0x80y, 0xFFy };

Joe Darcy is overseeing Project Coin for Java 7, and his blog has been an easy way to track these proposals.

According to this issue, --user is currently not valid inside a virtual env's pip, since a user location doesn't really make sense for a virtual environment.

So do not use pip install --user some_pkg inside a virtual environment, otherwise, virtual environment's pip will be confused. See this answer for more details.

While I was creating a reactive form, I had to assign 2 types of class on the button. This is how I did it:

<button type="submit" class="btn" [ngClass]="(formGroup.valid)?'btn-info':''" 
[disabled]="!formGroup.valid">Sign in</button>

When the form is valid, button has btn and btn-class (from bootstrap), otherwise just btn class.

1. Pig-latin is data flow style, is more suitable for software engineer. While sql is more suitable for analytics person who are get used to sql. For complex task, for hive you have to manually to create temporary table to store intermediate data, but it is not necessary for pig.

2. Pig-latin is suitable for complicated data structure( like small graph). There's a data structure in pig called DataBag which is a collection of Tuple. Sometimes you need to calculate metrics which involve multiple tuples ( there's a hidden link between tuples, in this case I would call it graph). In this case, it is very easy to write a UDF to calculate the metrics which involve multiple tuples. Of course it could be done in hive, but it is not so convenient as it is in pig.

3. Writing UDF in pig much is easier than in Hive in my opinion.

4. Pig has no metadata support, (or it is optional, in future it may integrate hcatalog). Hive has tables' metadata stored in database.

5. You can debug pig script in local environment, but it would be hard for hive to do that. The reason is point 3. You need to set up hive metadata in your local environment, very time consuming.

This looks a little better than your previous version but get rid of that .Activate on that line and see if you still get that error.

Dim sh1 As Worksheet
set sh1 = Workbooks.Add(filenum(lngPosition) & ".csv")

Creates a worksheet object. Not until you create that object do you want to start working with it. Once you have that object you can do the following:

sh1.Range("A69").Paste
sh1.Range("A69").Select

The sh1. explicitely tells Excel which object you are saying to work with... otherwise if you start selecting other worksheets while this code is running you could wind up pasting data to the wrong place.

str1 = "test123.00";
str2 = "yes50.00";
intStr1 = str1.replace(/[A-Za-z$-]/g, "");
intStr2 = str2.replace(/[A-Za-z$-]/g, "");
total = parseInt(intStr1)+parseInt(intStr2);

alert(total);

JetBrains offer a reasonable explanation,

"Ad-hoc conversion of data structures to text is largely dependent on the current culture, and may lead to unintended results when the code is executed on a machine whose locale differs from that of the original developer. To prevent ambiguities, ReSharper warns you of any instances in code where such a problem may occur."

but if I am working on a site I know will be in English only, I just ignore the suggestion.

You can solve this error by adding an argumentless constructor to the base class (as shown below).

Cheers.

 abstract public class BaseClass {
        // ADD AN ARGUMENTLESS CONSTRUCTOR TO THE BASE CLASS
        public BaseClass(){
        }

        String someString;
        public BaseClass(String someString) {
            this.someString = someString;
        }
        abstract public String getName();
    }

public class ACSubClass extends BaseClass {
    public ASubClass(String someString) {
        super(someString);
    }
    public String getName() {
        return "name value for ASubClass";
    }

That restricts T to reference types. You won't be able to put value types (structs and primitive types except string) there.

You need to use the various Bootstrap 4 centering methods...

• Use text-center for inline elements.
• Use justify-content-center for flexbox elements (ie; form-inline)

https://codeply.com/go/Am5LvvjTxC

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

<section id="cover">
    <div id="cover-caption">
        <div id="container" class="container">
            <div class="row">
                <div class="col-sm-10 offset-sm-1 text-center">
                    <h1 class="display-3">Welcome to Bootstrap 4</h1>
                    <div class="info-form">
                        <form action="" class="form-inline justify-content-center">
                            <div class="form-group">
                                <label class="sr-only">Name</label>
                                <input type="text" class="form-control" placeholder="Jane Doe">
                            </div>
                            <div class="form-group">
                                <label class="sr-only">Email</label>
                                <input type="text" class="form-control" placeholder="[email protected]">
                            </div>
                            <button type="submit" class="btn btn-success ">okay, go!</button>
                        </form>
                    </div>
                    <br>

                    <a href="#nav-main" class="btn btn-secondary-outline btn-sm" role="button">?</a>
                </div>
            </div>
        </div>
    </div>
</section>

I would say it depends on the context. strval() or the casting operator (string) could be used. However, in most cases PHP will decide what's good for you if, for example, you use it with echo or printf...

One small note: die() needs a string and won't show any int :)

The second (assuming you means CONTAINS, and actually put it in a valid query) should be faster, because it can use some form of index (in this case, a full text index). Of course, this form of query is only available if the column is in a full text index. If it isn't, then only the first form is available.

The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan.

The CONTAINS query should be:

SELECT * FROM table WHERE CONTAINS(Column, 'test');

This isn't a "slice", but it is a general solution that doesn't use explicit indexing, and works for the scenario where the sequence in question is anonymous (so you can create and "slice" on the same line, without creating twice and indexing twice): operator.itemgetter

import operator

# Done once and reused
first_and_last = operator.itemgetter(0, -1)

...

first, last = first_and_last(some_list)

You could just inline it as (after from operator import itemgetter for brevity at time of use):

first, last = itemgetter(0, -1)(some_list)

but if you'll be reusing the getter a lot, you can save the work of recreating it (and give it a useful, self-documenting name) by creating it once ahead of time.

Thus, for your specific use case, you can replace:

x, y = a.split("-")[0], a.split("-")[-1]

with:

x, y = itemgetter(0, -1)(a.split("-"))

and split only once without storing the complete list in a persistent name for len checking or double-indexing or the like.

Note that itemgetter for multiple items returns a tuple, not a list, so if you're not just unpacking it to specific names, and need a true list, you'd have to wrap the call in the list constructor.

For an example data in your table such as combinations of

'', null and as well as actual value than if you want to only actual value and replace to '' and null value by # symbol than execute this query

SELECT Column_Name = (CASE WHEN (Column_Name IS NULL OR Column_Name = '') THEN '#' ELSE Column_Name END) FROM Table_Name

and another way you can use it but this is little bit lengthy and instead of this you can also use IsNull function but here only i am mentioning IIF function

SELECT IIF(Column_Name IS NULL, '#', Column_Name) FROM Table_Name  
SELECT IIF(Column_Name  = '', '#', Column_Name) FROM Table_Name  
-- and syntax of this query
SELECT IIF(Column_Name IS NULL, 'True Value', 'False Value') FROM Table_Name

In my case I resolved this issue by

• clicking button Add which is next to the "Credentials" text
• adding credentials (login and password)
• selecting these credentials on the popup menu, which is on the left of the Add button
• waiting for a couple of seconds

My environment was Jenkins installed in the Windows. The UI question was why the warning was placed before the tool to resolve it.

You use the modulo operator:

while(score)
{
    printf("%d\n", score % 10);
    score /= 10;
}

Note that this will give you the digits in reverse order (i.e. least significant digit first). If you want the most significant digit first, you'll have to store the digits in an array, then read them out in reverse order.

Python doesn't have variable declarations, so it has to figure out the scope of variables itself. It does so by a simple rule: If there is an assignment to a variable inside a function, that variable is considered local.^[1] Thus, the line

counter += 1

implicitly makes counter local to increment(). Trying to execute this line, though, will try to read the value of the local variable counter before it is assigned, resulting in an UnboundLocalError.^[2]

If counter is a global variable, the global keyword will help. If increment() is a local function and counter a local variable, you can use nonlocal in Python 3.x.

What worked for me was the following command:

python -m pip install --upgrade pip

To create an option that needs no value, set the action ^[docs] of it to 'store_const', 'store_true' or 'store_false'.

PrincipalContext for browsing the AD is ridiculously slow (only use it for .ValidateCredentials, see below), use DirectoryEntry instead and .PropertiesToLoad() so you only pay for what you need.

        // I only care about what groups the user is a memberOf
        searcher.PropertiesToLoad.Add("memberOf");

        // FYI, non-null results means the user was found
        var results = searcher.FindOne();

        var properties = results?.Properties;
        if (properties?.Contains("memberOf") == true)
        {
            // ... iterate over all the groups the user is a member of
        }

}

Clean, simple, fast. No magic, no half-documented calls to .RefreshCache to grab the tokenGroups or to .Bind or .NativeObject in a try/catch to validate credentials.

For authenticating the user:

using (var context = new PrincipalContext(ContextType.Domain))
{
    return context.ValidateCredentials(username, password);
}

I know that this is rather old also. I recently had a need to create a context menu that I inject into other sites that have different properties based n the element clicked.

It's rather rough, and there are probable better ways to achieve this. It uses the jQuery Context menu Library Located Here

I enjoyed creating it and though that you guys might have some use out of it.

Here is the fiddle. I hope that it can hopefully help someone out there.

$(function() {
  function createSomeMenu() {
    var all_array = '{';
    var x = event.clientX,
      y = event.clientY,
      elementMouseIsOver = document.elementFromPoint(x, y);
    if (elementMouseIsOver.closest('a')) {
      all_array += '"Link-Fold": {"name": "Link", "icon": "fa-external-link", "items": {"fold2-key1": {"name": "Open Site in New Tab"}, "fold2-key2": {"name": "Open Site in Split Tab"}, "fold2-key3": {"name": "Copy URL"}}},';
    }
    if (elementMouseIsOver.closest('img')) {
      all_array += '"Image-Fold": {"name": "Image","icon": "fa-picture-o","items": {"fold1-key1": {"name":"Download Image"},"fold1-key2": {"name": "Copy Image Location"},"fold1-key3": {"name": "Go To Image"}}},';
    }
    all_array += '"copy": {"name": "Copy","icon": "copy"},"paste": {"name": "Paste","icon": "paste"},"edit": {"name": "Edit HTML","icon": "fa-code"}}';
    return JSON.parse(all_array);
  }

  // setup context menu
  $.contextMenu({
    selector: 'body',
    build: function($trigger, e) {
      return {
        callback: function(key, options) {
          var m = "clicked: " + key;
          console.log(m);
        },
        items: createSomeMenu()
      };
    }
  });
});

You can also do:

This works, but there may I'm not sure if it's supported in Django 2.

No command sbt found

It's saying that sbt is not on your path. Try to run ./sbt from ~/bin/sbt/bin or wherever the sbt executable is to verify that it runs correctly. Also check that you have execute permissions on the sbt executable. If this works , then add ~/bin/sbt/bin to your path and sbt should run from anywhere.

See this question about adding a directory to your path.

To verify the path is set correctly use the which command on LINUX. The output will look something like this:

$ which sbt
/usr/bin/sbt

Lastly, to verify sbt is working try running sbt -help or likewise. The output with -help will look something like this:

$ sbt -help
Usage: sbt [options]

  -h | -help         print this message

I solve the problem my issue was I had file named queue.py in the same directory

float price = 4.30;
DecimalFormat format = new DecimalFormat("0.##"); // Choose the number of decimal places to work with in case they are different than zero and zero value will be removed
format.setRoundingMode(RoundingMode.DOWN); // Choose your Rounding Mode
System.out.println(format.format(price));

This is the result of some tests:

4.30     => 4.3
4.39     => 4.39  // Choose format.setRoundingMode(RoundingMode.UP) to get 4.4
4.000000 => 4
4        => 4

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col

The code below gives the HEX and RGB value of the range whether formatted using conditional formatting or otherwise. If the range is not formatted using Conditional Formatting and you intend to use iColor function in the Excel as UDF. It won't work. Read the below excerpt from MSDN.

Note that the DisplayFormat property does not work in user defined functions. For example, in a worksheet function that returns the interior color of a cell, if you use a line similar to:

Range.DisplayFormat.Interior.ColorIndex

then the worksheet function executes to return a #VALUE! error. If you are not finding color of the conditionally formatted range, then I encourage you to rather use

Range.Interior.ColorIndex

as then the function can also be used as UDF in Excel. Such as iColor(B1,"HEX")

Public Function iColor(rng As Range, Optional formatType As String) As Variant
'formatType: Hex for #RRGGBB, RGB for (R, G, B) and IDX for VBA Color Index
    Dim colorVal As Variant
    colorVal = rng.DisplayFormat.Interior.Color
    Select Case UCase(formatType)
        Case "HEX"
            iColor = "#" & Format(Hex(colorVal Mod 256),"00") & _
                           Format(Hex((colorVal \ 256) Mod 256),"00") & _
                           Format(Hex((colorVal \ 65536)),"00")
        Case "RGB"
            iColor = Format((colorVal Mod 256),"00") & ", " & _
                     Format(((colorVal \ 256) Mod 256),"00") & ", " & _
                     Format((colorVal \ 65536),"00")
        Case "IDX"
            iColor = rng.Interior.ColorIndex
        Case Else
            iColor = colorVal
    End Select
End Function

'Example use of the iColor function
Sub Get_Color_Format()
    Dim rng As Range

    For Each rng In Selection.Cells
        rng.Offset(0, 1).Value = iColor(rng, "HEX")
        rng.Offset(0, 2).Value = iColor(rng, "RGB")
    Next
End Sub

++i is a pre-increment; i++ is post-increment.
The downside of post-increment is that it generates an extra value; it returns a copy of the old value while modifying i. Thus, you should avoid it when possible.

I prefer Buffer.from(data.Body).toString('utf8'). It supports encoding parameters. With other AWS services (ex. Kinesis Streams) someone may want to replace 'utf8' encoding with 'base64'.

new AWS.S3().getObject(
  { Bucket: this.awsBucketName, Key: keyName }, 
  function(err, data) {
    if (!err) {
      const body = Buffer.from(data.Body).toString('utf8');
      console.log(body);
    }
  }
);

This will provide you with the total memory in your system in human readable format and automatically scale to the appropriate unit ( e.g. bytes, KB, MB, or GB).

Follow a simple checklist:

1. Try pinging the machine ping 192.168.1.2
2. Ensure MySQL is running on the specified port 3306 i.e. it has not been modified.
3. Ensure that the other PC is not blocking inbound connections on that port. If it is, add a firewall exception to allow connections on port 3306 and allow inbound connections in general.
4. It would be nice if you could post the exact error as it is displayed when you attempt to make that connection.

If you aren't actually restricted to keeping all of these elements as sibling nodes you can wrap the ones that go together in another default flex box, and have the container of both use space-between.

.space-between {_x000D_
  border: 1px solid red;_x000D_
  display: flex;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.default-flex {_x000D_
  border: 1px solid blue;_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
}

<div class="space-between">_x000D_
  <div class="child">1</div>_x000D_
  <div class="default-flex">_x000D_
    <div class="child">2</div>_x000D_
    <div class="child">3</div>_x000D_
    <div class="child">4</div>_x000D_
    <div class="child">5</div>_x000D_
  </div>_x000D_
</div>

Or if you were doing the same thing with flex-start and flex-end reversed you just swap the order of the default-flex container and lone child.

Interface is the class that contains an abstract method that cannot create any object.Since Interface cannot create the object and its not a pure class, Its no worth implementing it.

use [\\W+] or "[^a-zA-Z0-9]" as regex to match any special characters and also use String.replaceAll(regex, String) to replace the spl charecter with an empty string. remember as the first arg of String.replaceAll is a regex you have to escape it with a backslash to treat em as a literal charcter.

          String c= "hjdg$h&jk8^i0ssh6";
        Pattern pt = Pattern.compile("[^a-zA-Z0-9]");
        Matcher match= pt.matcher(c);
        while(match.find())
        {
            String s= match.group();
        c=c.replaceAll("\\"+s, "");
        }
        System.out.println(c);

The accepted answer doesn't work if some package vendors it's own copy of urllib3, in which case this will still work:

A socket is a data I/O mechanism. A port is a contractual concept of a communication protocol. A socket can exist without a port. A port can exist witout a specific socket (e.g. if several sockets are active on the same port, which may be allowed for some protocols).

A port is used to determine which socket the receiver should route the packet to, with many protocols, but it is not always required and the receiving socket selection can be done by other means - a port is entirely a tool used by the protocol handler in the network subsystem. e.g. if a protocol does not use a port, packets can go to all listening sockets or any socket.

What's new in Python 3.0 says:

All text is Unicode; however encoded Unicode is represented as binary data

If you want to ensure you are outputting utf-8, here's an example from this page on unicode in 3.0:

b'\x80abc'.decode("utf-8", "strict")

Using ES6 string literals, would be much shorter:

const insertAt = (str, sub, pos) => `${str.slice(0, pos)}${sub}${str.slice(pos)}`;_x000D_
    _x000D_
console.log(insertAt('I want apple', ' an', 6)) // logs 'I want an apple'

Most likely the remote repository doesn't exist or you have added the wrong one.

You have to first remove the origin and re-add it:

git remote remove origin
git remote add origin https://github.com/username/repository

You just need to set the related drawables and set them in the checkbox:

<CheckBox 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:text="new checkbox" 
    android:background="@drawable/my_checkbox_background"
    android:button="@drawable/my_checkbox" />

The trick is on how to set the drawables. Here's a good tutorial about this.

strong and weak, these keywords revolves around Object Ownership in Objective-C

What is object ownership ?

Pointer variables imply ownership of the objects that they point to.

• When a method (or function) has a local variable that points to an object, that variable is said to own the object being pointed to.
• When an object has an instance variable that points to another object, the object with the pointer is said to own the object being pointed to.

Anytime a pointer variable points to an object, that object has an owner and will stay alive. This is known as a strong reference.

A variable can optionally not take ownership of an object that it points to. A variable that does not take ownership of an object is known as a weak reference.

Have a look for a detailed explanation here Demystifying @property and attributes

For me problem solved by changing http://ajax... into https://ajax... (add an S to http)

Why not create symlinks the other way around? Meaning instead of linking from the Git repository to the application directory, just link the other way around.

For example, let’s say I am setting up an application installed in ~/application that needs a configuration file config.conf:

• I add config.conf to my Git repository, for example, at ~/repos/application/config.conf.
• Then I create a symlink from ~/application by running ln -s ~/repos/application/config.conf.

This approach might not always work, but it worked well for me so far.

Speaking production, seamless failover/recovery both require a baby sitter
1- Couchbase, there is no seamless failover/recovery, manual intervention is required.
rebalancing takes too much time, too much risk if more than one node get lost.

2- Mongo with shards, data recovery from loosing a config server, is not an easy task

This is array initializer syntax, and it can only be used on the right-hand-side when declaring a variable of array type. Example:

int[] x = {1,2,3,4};
String y = {"a","b","c"};

If you're not on the RHS of a variable declaration, use an array constructor instead:

int[] x;
x = new int[]{1,2,3,4};
String y;
y = new String[]{"a","b","c"};

These declarations have the exact same effect: a new array is allocated and constructed with the specified contents.

In your case, it might actually be clearer (less repetitive, but a bit less concise) to specify the table programmatically:

double[][] m = new double[4][4];

for(int i=0; i<4; i++) {
    for(int j=0; j<4; j++) {
        m[i][j] = i*j;
    }
}

you can use scrollto(x,y) function to handle the position of scrollbar right to the point that you need to be showed after zooming.for finding the position of mouse use event.clientX and event.clientY. this will help you

If it outputs to stderr as well you'll want to silence that. You can do that by redirecting file descriptor 2:

# Send stdout to out.log, stderr to err.log
myprogram > out.log 2> err.log

# Send both stdout and stderr to out.log
myprogram &> out.log      # New bash syntax
myprogram > out.log 2>&1  # Older sh syntax

# Log output, hide errors.
myprogram > out.log 2> /dev/null

I use this simple playbook:

---
# vars.yml
#
# Shows the value of all variables/facts.
#
# Example:
#
#   ansible-playbook vars.yml -e 'hosts=localhost'
#
- hosts: localhost
  tasks:
    - fail: "You must specify a value for `hosts` variable - e.g.: ansible-playbook vars.yml -e 'hosts=localhost'"
      when: hosts is not defined

- hosts: "{{ hosts }}"
  tasks:
    - debug: var=vars
    - debug: var=hostvars[inventory_hostname]

Have seen this issue with Java 1.9 and SpringBoot 1.5.x, when main-class is not specified explicitly.

With Java 1.8, it is able to find main-class without explicit property and 'mvn package' works fine.

You can't change the margin of a table cell. But you CAN change the padding. Change the padding of the TD, which will make the cell larger and push the text away from the side with the increased padding. If you have border lines, however, it still won't be exactly what you want.

The javadoc of the File class describes the class as:

An abstract representation of file and directory pathnames.

File is only a representation of a pathname, with a few methods concerning the filesystem (like exists()) and directory handling but actual streaming input and output is done elsewhere. Streams can be opened and closed, files cannot.

(My personal opinion is that it's rather unfortunate that Sun then went on to create RandomAccessFile, causing much confusion with its inconsistent naming.)

I always use pseudo elements :before and :after for changing the appearance of checkboxes and radio buttons. it's works like a charm.

Steps

1. Hide the default checkbox using css rules like visibility:hidden or opacity:0 or position:absolute;left:-9999px etc.
2. Create a fake checkbox using :before element and pass either an empty or a non-breaking space '\00a0';
3. When the checkbox is in :checked state, pass the unicode content: "\2713", which is a checkmark;
4. Add :focus style to make the checkbox accessible.
5. Done

getent passwd | cut -d: -f1 | perl -e'while(<>){chomp;$l = `crontab -u $_ -l 2>/dev/null`;print "$_\n$l\n" if $l}'

This avoids messing with passwd directly, skips users that have no cron entries and for those who have them it prints out the username as well as their crontab.

Mostly dropping this here though so i can find it later in case i ever need to search for it again.

I had the same issue, ended up using the much more convenient Guava Resources:

Resources.getResource("my.file")

The compiler replaces null comparisons with a call to HasValue, so there is no real difference. Just do whichever is more readable/makes more sense to you and your colleagues.

Instead of having static methods and passing around a pointer to the class instance, you could use functionality in the new C++11 standard: std::function and std::bind:

#include <functional>
class EventHandler
{
    public:
        void addHandler(std::function<void(int)> callback)
        {
            cout << "Handler added..." << endl;
            // Let's pretend an event just occured
            callback(1);
        }
};

The addHandler method now accepts a std::function argument, and this "function object" have no return value and takes an integer as argument.

To bind it to a specific function, you use std::bind:

class MyClass
{
    public:
        MyClass();

        // Note: No longer marked `static`, and only takes the actual argument
        void Callback(int x);
    private:
        int private_x;
};

MyClass::MyClass()
{
    using namespace std::placeholders; // for `_1`

    private_x = 5;
    handler->addHandler(std::bind(&MyClass::Callback, this, _1));
}

void MyClass::Callback(int x)
{
    // No longer needs an explicit `instance` argument,
    // as `this` is set up properly
    cout << x + private_x << endl;
}

You need to use std::bind when adding the handler, as you explicitly needs to specify the otherwise implicit this pointer as an argument. If you have a free-standing function, you don't have to use std::bind:

void freeStandingCallback(int x)
{
    // ...
}

int main()
{
    // ...
    handler->addHandler(freeStandingCallback);
}

Having the event handler use std::function objects, also makes it possible to use the new C++11 lambda functions:

handler->addHandler([](int x) { std::cout << "x is " << x << '\n'; });

Use the following command:

in.nextLine();

right after

System.out.println("Invalid input. Please Try Again.");
System.out.println();

or after the following curly bracket (where your comment regarding it, is).

This command advances the scanner to the next line (when reading from a file or string, this simply reads the next line), thus essentially flushing it, in this case. It clears the buffer and readies the scanner for a new input. It can, preferably, be used for clearing the current buffer when a user has entered an invalid input (such as a letter when asked for a number).

Documentation of the method can be found here: http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html#nextLine()

Hope this helps!

You're close.

The LIKE operator works with strings (CHAR, NVARCHAR, etc). so you need to concattenate the '%' symbol to the string...

MS SQL Server:

SELECT * FROM table1,table2 WHERE table1.x LIKE table2.y + '%'

Use of LIKE, however, is often slower than other operations. It's useful, powerful, flexible, but has performance considerations. I'll leave those for another topic though :)

EDIT:

I don't use MySQL, but this may work...

SELECT * FROM table1,table2 WHERE table1.x LIKE CONCAT(table2.y, '%')

If you are aware of bootstrap you can do it easily by using 'flex' property.All you need to do is pass below css properties to parent div

.homepageSection {
  overflow: hidden;
  height: auto;
  display: flex;
  flex-flow: row;
}

where .homepageSection is my parent div. Now add child div in your html as

<div class="abc col-md-6">
<div class="abc col-md-6">

where abc is my child div.You can check equality of height in both child div irrespective of border just by giving border to child div

Try this php code.

<?PHP

function getUserIP()
{
    // Get real visitor IP behind CloudFlare network
    if (isset($_SERVER["HTTP_CF_CONNECTING_IP"])) {
              $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
              $_SERVER['HTTP_CLIENT_IP'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
    }
    $client  = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote  = $_SERVER['REMOTE_ADDR'];

    if(filter_var($client, FILTER_VALIDATE_IP))
    {
        $ip = $client;
    }
    elseif(filter_var($forward, FILTER_VALIDATE_IP))
    {
        $ip = $forward;
    }
    else
    {
        $ip = $remote;
    }

    return $ip;
}


$user_ip = getUserIP();

echo $user_ip; // Output IP address [Ex: 177.87.193.134]

No need to bother with iTunesConnect for sharing your adhoc builds. Just upload your ipa file to diawi and after successful uploading you will get a link open the link in safari and you will be asked to install app. Tap on install and enjoy

You need to specify the minimum width of the field.

String.format("%" + numberOfSpaces + "s", ""); 

Why do you want to generate a String of spaces of a certain length.

If you want a column of this length with values then you can do:

String.format("%" + numberOfSpaces + "s", "Hello"); 

which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

exit(int code); is declared in stdlib.h so you need an

#include <stdlib.h>

Also:
- You have no parameter for the exit(), it requires an int so provide one.
- Burn this book, it uses goto which is (for everyone but linux kernel hackers) bad, very, very, VERY bad.

Edit:
Oh, and

void main()

is bad, too, it's:

int main(int argc, char *argv[])

I found following way which can be used if you KNOW name of lock

select IS_USED_LOCK('lockname');

however i not found any info about how to list all names.

After socket.io 1.0 we cannot use

io.sockets.clients(); 
or
io.sockets.clients('room'); 

anymore. Instead you can use the following

var clients_in_the_room = io.sockets.adapter.rooms[roomId]; 
for (var clientId in clients_in_the_room ) {
  console.log('client: %s', clientId); //Seeing is believing 
  var client_socket = io.sockets.connected[clientId];//Do whatever you want with this
}

just return true inside your if statement

var myArr = [1,2,3,4];

myArr.forEach(function(elem){
  if (elem === 3) {

      return true;

    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

GPL-compiled ffmpeg can be used from non-GPL program (commercial project) only if it is invoked in the separate process as command line utility; all wrappers that are linked with ffmpeg library (including Microsoft's FFMpegInterop) can use only LGPL build of ffmpeg.

You may try my .NET wrapper for FFMpeg: Video Converter for .NET (I'm an author of this library). It embeds FFMpeg.exe into the DLL for easy deployment and doesn't break GPL rules (FFMpeg is NOT linked and wrapper invokes it in the separate process with System.Diagnostics.Process).

Method __str__ should return string, not print.

def __str__(self):

You can use position:absolute to position an overlay inside of your div and then stretch it in all directions like so:

CSS ^{updated *}

.overlay {
    position:absolute;
    top:0;
    left:0;
    right:0;
    bottom:0;
    background-color:rgba(0, 0, 0, 0.85);
    background: url(data:;base64,iVBORw0KGgoAAAANSUhEUgAAAAIAAAACCAYAAABytg0kAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwAADqYAAAOpgAABdwnLpRPAAAABl0RVh0U29mdHdhcmUAUGFpbnQuTkVUIHYzLjUuNUmK/OAAAAATSURBVBhXY2RgYNgHxGAAYuwDAA78AjwwRoQYAAAAAElFTkSuQmCC) repeat scroll transparent\9; /* ie fallback png background image */
    z-index:9999;
    color:white;
}

You just need to make sure that your parent div has the position:relative property added to it and a lower z-index.

Made a demo that should work in all browsers, including IE7+, for a commenter below.

Demo

Removed the opacity property from the css and instead used an rGBA color to give the background, and only the background, an opacity level. This way the content that the overlay carries will not be affected. Since IE does not support rGBA i used an IE hack instead to give it an base64 encoded PNG background image that fills the overlay div instead, this way we can evade IEs opacity issue where it applies the opacity to the children elements as well.

It's a new era and with Python 3.6.1 dictionaries now retain their order. These semantics aren't explicit because that would require BDFL approval. But Raymond Hettinger is the next best thing (and funnier) and he makes a pretty strong case that dictionaries will be ordered for a very long time.

So now it's easy to create slices of a dictionary:

test_dict = {
                'first':  1,
                'second': 2,
                'third':  3,
                'fourth': 4
            }

list(test_dict.items())[:2]

Note: Dictonary insertion-order preservation is now official in Python 3.7.

you should return Scaffold widget and add your widget inside Scaffold

suck as this code :

import 'package:flutter/material.dart';

void main() {
  runApp(new MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return Scaffold(
          backgroundColor: Colors.white,
          body: Center(child: new Text("Hello, World!"));
    );
  }
}

Set your working directory one level/folder higher. For example, if it is already set as:

setwd("C:/Users/Z/Desktop/Files/RStudio/Coursera/specdata")

go up one level back and set it as:

setwd("C:/Users/Z/Desktop/Files/RStudio/Coursera")

In other words, do not make "specdata" folder as your working directory.

try this:

bigInt.sign = number < 0 ? 0 : 1

With Spring 3.0 you can use the HttpEntity return object. If you use this, then your controller does not need a HttpServletResponse object, and therefore it is easier to test. Except this, this answer is relative equals to the one of Infeligo.

If the return value of your pdf framework is an byte array (read the second part of my answer for other return values) :

@RequestMapping(value = "/files/{fileName}", method = RequestMethod.GET)
public HttpEntity<byte[]> createPdf(
                 @PathVariable("fileName") String fileName) throws IOException {

    byte[] documentBody = this.pdfFramework.createPdf(filename);

    HttpHeaders header = new HttpHeaders();
    header.setContentType(MediaType.APPLICATION_PDF);
    header.set(HttpHeaders.CONTENT_DISPOSITION,
                   "attachment; filename=" + fileName.replace(" ", "_"));
    header.setContentLength(documentBody.length);

    return new HttpEntity<byte[]>(documentBody, header);
}

If the return type of your PDF Framework (documentBbody) is not already a byte array (and also no ByteArrayInputStream) then it would been wise NOT to make it a byte array first. Instead it is better to use:

• InputStreamResource,
• PathResource (since Spring 4.0) or
• FileSystemResource,

example with FileSystemResource:

@RequestMapping(value = "/files/{fileName}", method = RequestMethod.GET)
public HttpEntity<byte[]> createPdf(
                 @PathVariable("fileName") String fileName) throws IOException {

    File document = this.pdfFramework.createPdf(filename);

    HttpHeaders header = new HttpHeaders();
    header.setContentType(MediaType.APPLICATION_PDF);
    header.set(HttpHeaders.CONTENT_DISPOSITION,
                   "attachment; filename=" + fileName.replace(" ", "_"));
    header.setContentLength(document.length());

    return new HttpEntity<byte[]>(new FileSystemResource(document),
                                  header);
}

I did a little experiment to see which of these methods

• string.startswith('hello')
• string.rfind('hello') == 0
• string.rpartition('hello')[0] == ''
• string.rindex('hello') == 0

are most efficient to return whether a certain string begins with another string.

Here is the result of one of the many test runs I've made, where each list is ordered to show the least time it took (in seconds) to parse 5 million of each of the above expressions during each iteration of the while loop I used:

['startswith: 1.37', 'rpartition: 1.38', 'rfind: 1.62', 'rindex: 1.62']

['startswith: 1.35', 'rpartition: 1.42', 'rfind: 1.63', 'rindex: 1.68']
['startswith: 1.32', 'rpartition: 1.46', 'rfind: 1.65', 'rindex: 1.75']
['startswith: 1.37', 'rpartition: 1.46', 'rfind: 1.74', 'rindex: 1.75']
['startswith: 1.31', 'rpartition: 1.48', 'rfind: 1.67', 'rindex: 1.74']
['startswith: 1.44', 'rpartition: 1.46', 'rindex: 1.69', 'rfind: 1.74']
['startswith: 1.44', 'rpartition: 1.42', 'rfind: 1.65', 'rindex: 1.65']
['startswith: 1.36', 'rpartition: 1.44', 'rfind: 1.64', 'rindex: 1.74']
['startswith: 1.34', 'rpartition: 1.46', 'rfind: 1.61', 'rindex: 1.74']
['startswith: 1.35', 'rpartition: 1.56', 'rfind: 1.68', 'rindex: 1.69']
['startswith: 1.32', 'rpartition: 1.48', 'rindex: 1.64', 'rfind: 1.65']
['startswith: 1.28', 'rpartition: 1.43', 'rfind: 1.59', 'rindex: 1.66']

I believe that it is pretty obvious from the start that the startswith method would come out the most efficient, as returning whether a string begins with the specified string is its main purpose.

What surprises me is that the seemingly impractical string.rpartition('hello')[0] == '' method always finds a way to be listed first, before the string.startswith('hello') method, every now and then. The results show that using str.partition to determine if a string starts with another string is more efficient then using both rfind and rindex.

Another thing I've noticed is that string.rindex('hello') == 0 and string.rindex('hello') == 0 have a good battle going on, each rising from fourth to third place, and dropping from third to fourth place, which makes sense, as their main purposes are the same.

Here is the code:

from time import perf_counter

string = 'hello world'
places = dict()

while True:
    start = perf_counter()
    for _ in range(5000000):
        string.startswith('hello')
    end = perf_counter()
    places['startswith'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rfind('hello') == 0
    end = perf_counter()
    places['rfind'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rpartition('hello')[0] == ''
    end = perf_counter()
    places['rpartition'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rindex('hello') == 0
    end = perf_counter()
    places['rindex'] = round(end - start, 2)
    
    print([f'{b}: {str(a).ljust(4, "4")}' for a, b in sorted(i[::-1] for i in places.items())])

I am not sure it would read better but you could do the following:

while any((not condition1, not condition2, val == -1)):
    val,something1,something2 = getstuff()

    if something1==10:
        condition1 = True

    if something2==20:
        condition2 = True

You should group by the field you want the SUM apply to, and not include in SELECT any field other than multiple rows values, like COUNT, SUM, AVE, etc, because if you include Bill field like in this case, only the first value in the set of rows will be displayed, being almost meaningless and confusing.

This will return the sum of bills per account number:

SELECT SUM(Bill) FROM Table1 GROUP BY AccountNumber

You could add more clauses like WHERE, ORDER BY etc as needed.

Use this

//*[@id='popover-search']/div/div/ul/li[1]/a/span[contains(text(),'Some text')]

OR

//*[@id='popover-search']/div/div/ul/li[1]/a/span[contains(.,'Some text')]

It might be easier with vlookup. Try this:

=IFERROR(VLOOKUP(D2,G:H,2,0),"")

The IFERROR() is for no matches, so that it throws "" in such cases.

VLOOKUP's first parameter is the value to 'look for' in the reference table, which is column G and H.

VLOOKUP will thus look for D2 in column G and return the value in the column index 2 (column G has column index 1, H will have column index 2), meaning that the value from column H will be returned.

The last parameter is 0 (or equivalently FALSE) to mean an exact match. That's what you need as opposed to approximate match.

There is a useful Web API method called URL

const url = new URL('http://www.somedomain.com/account/search?filter=a#top');_x000D_
console.log(url.pathname.split('/'));_x000D_
const params = new URLSearchParams(url.search)_x000D_
console.log(params.get("filter"))

On my system it went like this:

On my Android device in my Linux shell, a simple "ifconfig" did not give me my IP address. I had to type:

ifconfig eth0

-or-

netcfg

to get my IP address. (I knew eth0 was configured because I saw it in my dmesg.) Then I did the :

setprop service.adb.tcp.port -1

stop adbd

start adbd

Then on my Win7 box (the one running Eclipse 3.7.1). I opened a command prompt to

\android-sdk\platform-tools>

without running as admin. Then I did a

adb connect 12.345.678.90

I never put a port. If I did a

adb tcpip 5555

it said it couldn't find the device then nothing appeared in my "adb devices" list. I.e. it only works if I DON'T do the tcpip command above.

I can do an "adb shell" and mess with my Android Device. But my Android Device does not appear in my Run->Run Configurations->Target tab right now. On the other hand, if I keep the Target Tab set to automatic. Then when I run my app via Run->Run it does run on my Android device even though my Android device is not even listed as one of my targets.

Resource-Only DLL is an option for you. But it is not required necessarily unless you want to modify resources without recompiling applications. Have just one common ResourceDictionary file is also an option. It depends how often you change resources and etc.

<ResourceDictionary Source="pack://application:,,,/
     <MyAssembly>;component/<FolderStructureInAssembly>/<ResourceFile.xaml>"/>

MyAssembly - Just assembly name without extension

FolderStructureInAssembly - If your resources are in a folde, specify folder structure

When you are doing this it's better to aware of siteOfOrigin as well.

WPF supports two authorities: application:/// and siteoforigin:///. The application:/// authority identifies application data files that are known at compile time, including resource and content files. The siteoforigin:/// authority identifies site of origin files. The scope of each authority is shown in the following figure.

Consider the option of encapsulating this particular dictionary and provide a method to return the value for that key:

public static class NumbersAdapter
{
    private static readonly Dictionary<string, string> Mapping = new Dictionary<string, string>
    {
        ["1"] = "One",
        ["2"] = "Two",
        ["3"] = "Three"
    };

    public static string GetValue(string key)
    {
        return Mapping.ContainsKey(key) ? Mapping[key] : key;
    }
}

Then you can manage the behaviour of this dictionary.

For example here: if the dictionary doesn't have the key, it returns key that you pass by parameter.

When we first moved over to Vista with Oracle 10g, we experienced this issue when we installed the Oracle client on our Vista boxes, even when we were running with admin privileges during install.

Oracle brought out a new version of the 10g client (10.2.0.3) that was Vista compatible.

I do believe that this was after 11g was released, so it is possible that there is a 'Vista compatible' version for 11g also.

If you're concatenating strings to build file paths, use the Join-Path command:

Join-Path C:\temp "MyNewFolder"

It'll automatically add the appropriate trailing / leading slashes for you, which makes things a lot easier.

You can have multiple <context:property-placeholder /> elements instead of explicitly declaring multiple PropertiesPlaceholderConfigurer beans.

Try to use pointers...

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

int main()
{

  char str[] = "String1 subString1 Strinstrnd subStr ing1subString";
  char sub[] = "subString";

  char *p1, *p2, *p3;
  int i=0,j=0,flag=0;

  p1 = str;
  p2 = sub;

  for(i = 0; i<strlen(str); i++)
  {
    if(*p1 == *p2)
      {
          p3 = p1;
          for(j = 0;j<strlen(sub);j++)
          {
            if(*p3 == *p2)
            {
              p3++;p2++;
            } 
            else
              break;
          }
          p2 = sub;
          if(j == strlen(sub))
          {
             flag = 1;
            printf("\nSubstring found at index : %d\n",i);
          }
      }
    p1++; 
  }
  if(flag==0)
  {
       printf("Substring NOT found");
  }
return (0);
}

This work for me!

Here is my way:

Let's say the branch name is develop.

# Create a new temp branch based on one history commit
git checkout <last_known_good_commit_hash>
git checkout -b develop-temp

# Delete the original develop branch and 
# create a new branch with the same name based on the develop-temp branch
git branch -D develop
git checkout -b develop

# Force update this new branch
git push -f origin develop

# Remove the temp branch
git branch -D develop-temp

@owlstead, regarding your request for "a cryptographically secure variant of one of the given answers," please see RNCryptor. It was designed to do exactly what you're requesting (and was built in response to the problems with the code listed here).

RNCryptor uses PBKDF2 with salt, provides a random IV, and attaches HMAC (also generated from PBKDF2 with its own salt. It support synchronous and asynchronous operation.

Unlike other answers, the UrlSearchParams object can avoid using Regexes or other string manipulation and is available is most modern browsers:

var queryString = location.search
let params = new URLSearchParams(queryString)
// example of retrieving 'id' parameter
let id = parseInt(params.get("id"))
console.log(id)

The answer to this is CSS Specificity. You need to be more "specific" in your CSS so that it can override bootstrap css properties.

For example you have a sample code for a bootstrap menu here:

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
    <div id="home-menu-container" class="collapse navbar-collapse">
        <ul id="home-menu" class="nav navbar-nav">
            <li><a class="navbar-brand" href="#"><img src="images/xd_logo.png" /></a></li>
            <li><a href="#intro">Home</a></li>
            <li><a href="#about">About Us</a></li>

            <li><a href="#contact">Contact Us</a></li>
        </ul>
    </div><!-- /.navbar-collapse -->
</nav>

Here, you need to remember the hierarchy of the specificity. It goes like this:

• Give an element with an id mentioned 100 points
• Give an element with a class mentioned 10 points
• Give a simple element a single 1 point

So, for the above if your css has something like this:

.navbar ul li a { color: red; } /* 10(.navbar) + 1(ul) + 1(li) + 1(a) = 13 points */
.navbar a { color: green; } /* 10(.navbar) + 1(a) = 11 points */

So, even if you have defined the .navbar a after .navbar ul li a it is still going to override with a red colour, instead of a green since the specificity is more (13 points).

So, basically all you need to do is calculate the points for the element you are wanting to change the css for, via inspect element on your browser. Here, bootstrap has specified its css for the element as

.navbar-inverse .navbar-nav>li>a { /* Total = 22 points */
    color: #999;
}

So, even if your css is loading is being loaded after bootstrap.css which has the following line:

.navbar-nav li a {
    color: red;
}

it's still going to be rendered as #999. In order to solve this, bootstrap has 22 points (calculate it yourself). So all we need is something more than that. Thus, I have added custom IDs to the elements i.e. home-menu-container and home-menu. Now the following css will work:

#home-menu-container #home-menu li a { color: red; } /* 100 + 100 + 1 + 1 = 202 points :) */

Done.

If you add a Selection and saving to workbook path to Ryan Bradley code that will be more elastic:

 Sub ExportImage()

Dim sheet, zoom_coef, area, chartobj
Dim sFilePath As String
Dim sView As String

'Captures current window view
sView = ActiveWindow.View

'Sets the current view to normal so there are no "Page X" overlays on the image
ActiveWindow.View = xlNormalView

'Temporarily disable screen updating
Application.ScreenUpdating = False

Set sheet = ActiveSheet

'Set the file path to export the image to the user's desktop
'I have to give credit to Kyle for this solution, found it here:
'http://stackoverflow.com/questions/17551238/vba-how-to-save-excel-workbook-to-desktop-regardless-of-user
'sFilePath = CreateObject("WScript.Shell").specialfolders("Desktop") & "\" & ActiveSheet.Name & ".png"

'##################
'Lukasz : Save to  workbook directory
'Asking for filename insted of ActiveSheet.Name is also good idea, without file extension
dim FileID as string
FileID=inputbox("Type a file name","Filename...?",ActiveSheet.Name)
sFilePath = ThisWorkbook.Path & "\" & FileID & ".png"

'Lukasz:Change code to use Selection
'Simply select what you want to export and run the macro

Dim r As Long, c As Integer, ar As Long, ac As Integer

    r = Selection.rows.Count
    c = Selection.Columns.Count
    ar = ActiveCell.Row
    ac = ActiveCell.Column
    ActiveSheet.PageSetup.PrintArea = Range(Cells(ar, ac), Cells(ar, ac)).Resize(r, c).Address

'Export print area as correctly scaled PNG image, courtasy of Winand

Short answer: AngularJS ("jqlite") doesn't support this. Include jQuery on your page (before including Angular), and it should work. See https://groups.google.com/d/topic/angular/H4haaMePJU0/discussion

After lots of research, I solve this issue with hint from ofir_aghai answer about script load event.

Basically we need to use $ for jQuery code, but we can't use it till jQuery is loaded. I used document.createElement() to add a script for jQuery, but the issue is that it takes time to load while the next statement in JavaScript using $ fails. So, I used the below solution.

myscript.js is having code which uses jQuery main.js is used to load both jquery.min.js and myscript.js files making sure that jQuery is loaded.

main.js code

window.load = loadJQueryFile();
var heads = document.getElementsByTagName('head');

function loadJQueryFile(){
    var jqueryScript=document.createElement('script');
    jqueryScript.setAttribute("type","text/javascript");
    jqueryScript.setAttribute("src", "/js/jquery.min.js");

    jqueryScript.onreadystatechange = handler;
    jqueryScript.onload = handler;  
    heads[0].appendChild(jqueryScript);
}

function handler(){
    var myScriptFile=document.createElement('script');
    myScriptFile.setAttribute("type","text/javascript");
    myScriptFile.setAttribute("src", "myscript.js");
    heads[0].appendChild(myScriptFile);
 }

This way it worked. Using loadJQueryFile() from myscript.js didn't work. It immediately goes to the next statement which uses $.

Best and the simple way of doing is :

Just use the default way from Sequelize

db.Sensors.findAll({
    where: {
        nodeid: node.nodeid
    },
    raw : true // <----------- Magic is here
}).success(function (sensors) {
        console.log(sensors);
});

Note : [options.raw] : Return raw result. See sequelize.query for more information.

For the nested result/if we have include model , In latest version of sequlize ,

db.Sensors.findAll({
    where: {
        nodeid: node.nodeid
    },
    include : [
        { model : someModel }
    ]
    raw : true , // <----------- Magic is here
    nest : true // <----------- Magic is here
}).success(function (sensors) {
        console.log(sensors);
});

Try this :

odd :

select * from( 
SELECT col1, col2, ROW_NUMBER() OVER(ORDER BY col1 DESC) AS 'RowNumber', 
FROM table1
) d where (RowNumber % 2) = 1 

even :

select * from( 
SELECT col1, col2, ROW_NUMBER() OVER(ORDER BY col1 DESC) AS 'RowNumber', 
FROM table1
) d where (RowNumber % 2) = 0

I am in the same boot like you. In the case you mention, I would implement the input validation UI component as a React component.

I agree the implementation of the validation logic itself should (must) not be coupled. Therefore I would put it into a separate JS module.

That is, for logic that should not be coupled use a JS module/class in separate file, and use require/import to de-couple the component from the "service".

This allows for dependency injection and unit testing of the two independently.

What you are looking for is a pseudo-element that doesn't exist. There is :first-letter and :first-line, but no :first-word.

You can of course do this with JavaScript. Here's some code I found that does this: http://www.dynamicsitesolutions.com/javascript/first-word-selector/

python -c "exec(open('main.py').read())"

egyamado's answer was really helpful! You can enhance it for your particular setup with something like this:

import sublime, sublime_plugin
import webbrowser

class OpenBrowserCommand(sublime_plugin.TextCommand):
   def run(self, edit, keyPressed, localHost, pathToFiles):  
      for region in self.view.sel():  
         if not region.empty():  
            # Get the selected text  
            url = self.view.substr(region)  
            # prepend beginning of local host url 
            url = localHost + url  
         else:
            # prepend beginning of local host url 
            url = localHost + self.view.file_name()
            # replace local path to file
            url = url.replace(pathToFiles, "")


         if keyPressed == "1":
            navigator = webbrowser.get("open -a /Applications/Firefox.app %s")
         if keyPressed == "2":
            navigator = webbrowser.get("open -a /Applications/Google\ Chrome.app %s")
         if keyPressed == "3":
            navigator = webbrowser.get("open -a /Applications/Safari.app %s")
         navigator.open_new(url)

And then in your keybindings:

{ "keys": ["alt+1"], "command": "open_browser", "args": {"keyPressed": "1", "localHost": "http://nbrown.smartdestinations.com", "pathToFiles":"/opt/local/apache2/htdocs"}},
{ "keys": ["alt+2"], "command": "open_browser", "args": {"keyPressed": "2", "localHost": "http://nbrown.smartdestinations.com", "pathToFiles":"/opt/local/apache2/htdocs"}},
{ "keys": ["alt+3"], "command": "open_browser", "args": {"keyPressed": "3", "localHost": "http://nbrown.smartdestinations.com", "pathToFiles":"/opt/local/apache2/htdocs"}}

We store sample urls at the top of all our templates, so the first part allows you to highlight that sample URL and launch it in a browser. If no text is highlighted, it will simply use the file name. You can adjust the command calls in the keybindings to your localhost url and the system path to the documents you're working on.

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

However, the support for dashed lines depends on the selected terminal:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

Running

set terminal pngcairo dashed
set output 'test.png'
test
set output

gives:

whereas, the postscript terminal shows different dash patterns:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

Version 5.0

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• A new dashtype parameter was introduced:

  To get the predefined dash patterns, use e.g.

  plot x dashtype 2
  

  You can also specify custom dash patterns like

  plot x dashtype (3,5,10,5),\
       2*x dashtype '.-_'
  

• The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

  set for [i=1:8] linetype i dashtype i
  

• The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:

You can try this code

String[] stringA = new String[stringArrayList.size()];
stringArrayList.toArray(stringA)
System.out.println(stringA[0]);

If you're having this issue while using an sql-server with the sequelize-typescript npm make sure to add @AutoIncrement to ID column:

  @PrimaryKey
  @AutoIncrement
  @Column
  id!: number;

It needs to work with the transparent background in a spinner.

Do you mean altering the table after it has been created? If so you need to use alter table, in particular:

ALTER TABLE tablename MODIFY COLUMN new-column-definition

e.g.

ALTER TABLE test MODIFY COLUMN locationExpect VARCHAR(120);

Thanks to Ian Henry!

In case if you need to get file from MS SQL Server here is the solution.

public FileResult DownloadDocument(string id)
        {
            if (!string.IsNullOrEmpty(id))
            {
                try
                {
                    var fileId = Guid.Parse(id);

                    var myFile = AppModel.MyFiles.SingleOrDefault(x => x.Id == fileId);

                    if (myFile != null)
                    {
                        byte[] fileBytes = myFile.FileData;
                        return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, myFile.FileName);
                    }
                }
                catch
                {
                }
            }

            return null;
        }

Where AppModel is EntityFramework model and MyFiles presents table in your database. FileData is varbinary(MAX) in MyFiles table.

for color in ['r', 'b', 'g', 'k', 'm']:
    plot(x, y, color=color)

SELECT CAST(CAST('000000000' AS INTEGER) AS VARCHAR)

This has a limit on the length of the string that can be converted to an INT

In my experience, this error is frequently caused by a spelling error.

I got this error today.

make[1]: *** No rule to make target maintenaceDialog.cpp', needed bymaintenaceDialog.o'. Stop.

In my case the error was simply a spelling error. The word MAINTENANCE was missing it's third N.

Also check the spelling on your filenames.

Best way to use UserDefaults

Steps

1. Create extension of UserDefaults
2. Create enum with required Keys to store in local
3. Store and retrieve the local data wherever you want

Sample

extension UserDefaults{

    //MARK: Check Login
    func setLoggedIn(value: Bool) {
        set(value, forKey: UserDefaultsKeys.isLoggedIn.rawValue)
        //synchronize()
    }

    func isLoggedIn()-> Bool {
        return bool(forKey: UserDefaultsKeys.isLoggedIn.rawValue)
    }

    //MARK: Save User Data
    func setUserID(value: Int){
        set(value, forKey: UserDefaultsKeys.userID.rawValue)
        //synchronize()
    }

    //MARK: Retrieve User Data
    func getUserID() -> Int{
        return integer(forKey: UserDefaultsKeys.userID.rawValue)
    }
}

enum for Keys used to store data

enum UserDefaultsKeys : String {
    case isLoggedIn
    case userID
}

Save in UserDefaults where you want

UserDefaults.standard.setLoggedIn(value: true)          // String
UserDefaults.standard.setUserID(value: result.User.id!) // String

Retrieve data anywhere in app

print("ID : \(UserDefaults.standard.getUserID())")
UserDefaults.standard.getUserID()

Remove Values

UserDefaults.standard.removeObject(forKey: UserDefaultsKeys.userID) 

This way you can store primitive data in best

Update You need no use synchronize() to store the values. As @Moritz pointed out the it unnecessary and given the article about it.Check comments for more detail

In repo_a:

git remote add -f b path/to/repo_b.git
git remote update
git diff master remotes/b/master
git remote rm b

This script demonstrates a few ways to show the local timezone using astimezone():

#!/usr/bin/env python3

import pytz
from datetime import datetime, timezone
from tzlocal import get_localzone

utc_dt = datetime.now(timezone.utc)

PST = pytz.timezone('US/Pacific')
EST = pytz.timezone('US/Eastern')
JST = pytz.timezone('Asia/Tokyo')
NZST = pytz.timezone('Pacific/Auckland')

print("Pacific time {}".format(utc_dt.astimezone(PST).isoformat()))
print("Eastern time {}".format(utc_dt.astimezone(EST).isoformat()))
print("UTC time     {}".format(utc_dt.isoformat()))
print("Japan time   {}".format(utc_dt.astimezone(JST).isoformat()))

# Use astimezone() without an argument
print("Local time   {}".format(utc_dt.astimezone().isoformat()))

# Use tzlocal get_localzone
print("Local time   {}".format(utc_dt.astimezone(get_localzone()).isoformat()))

# Explicitly create a pytz timezone object
# Substitute a pytz.timezone object for your timezone
print("Local time   {}".format(utc_dt.astimezone(NZST).isoformat()))

It outputs the following:

$ ./timezones.py 
Pacific time 2019-02-22T17:54:14.957299-08:00
Eastern time 2019-02-22T20:54:14.957299-05:00
UTC time     2019-02-23T01:54:14.957299+00:00
Japan time   2019-02-23T10:54:14.957299+09:00
Local time   2019-02-23T14:54:14.957299+13:00
Local time   2019-02-23T14:54:14.957299+13:00
Local time   2019-02-23T14:54:14.957299+13:00

As of python 3.6 calling astimezone() without a timezone object defaults to the local zone (docs). This means you don't need to import tzlocal and can simply do the following:

#!/usr/bin/env python3

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc)

print("Local time {}".format(utc_dt.astimezone().isoformat()))

You can also move mounted out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.

function init() {
  // Use `this` normally
}

new Vue({
  methods:{
    init
  },
  mounted(){
    init.call(this)
  }
})

instead of declaring as int i declare it as Integer i then we can do i=null;

Integer i;
i=null;

     function my_simple_crypt( $string, $action = 'e' ) {
        // you may change these values to your own
        $secret_key = 'my_simple_secret_key';
        $secret_iv = 'my_simple_secret_iv';

        $output = false;
        $encrypt_method = "AES-256-CBC";
        $key = hash( 'sha256', $secret_key );
        $iv = substr( hash( 'sha256', $secret_iv ), 0, 16 );

        if( $action == 'e' ) {
            $output = base64_encode( openssl_encrypt( $string, $encrypt_method, $key, 0, $iv ) );
        }
        else if( $action == 'd' ){
            $output = openssl_decrypt( base64_decode( $string ), $encrypt_method, $key, 0, $iv );
        }

        return $output;
    }

How do I print out my $ids and $nIds?

print "$ids\n";
print "$nIds\n";

I tried simply print $ids, but Perl complains.

Complains about what? Uninitialised value? Perhaps your loop was never entered due to an error opening the file. Be sure to check if open returned an error, and make sure you are using use strict; use warnings;.

my ($ids, $nIds) is a list, right? With two elements?

It's a (very special) function call. $ids,$nIds is a list with two elements.

I'd like to add that TypeGuards only work on strings or numbers, if you want to compare an object use instanceof

if(task.id instanceof UUID) {
  //foo
}

You can use any on process for dynamic path on command prompt

Process p = Runtime.getRuntime().exec("cmd.exe /c start dir ");
Process p = Runtime.getRuntime().exec("cmd.exe /c start cd \"E:\\rakhee\\Obligation Extractions\" && dir");
Process p = Runtime.getRuntime().exec("cmd.exe /c start cd \"E:\\oxyzen-workspace\\BrightleafDesktop\\Obligation Extractions\" && dir");

I know this topic is old, but for future people who could wonder the same question, another incredibly inefficient solution could be to do:

PersonModel.find({$where : 'this.favouriteFoods.indexOf("sushi") != -1'});

This avoids all optimisations by MongoDB so do not use in production code.

this worked for me inside a directive and works without refreshing the baseurl (just adds the endpoint).Good for Single Page Apps with routing mechanism.

  $(location).attr('href', 'http://localhost:10005/#/endpoint') 

In com.sun.jna.Platform class you can find useful static methods like

Platform.isWindows();
Platform.is64Bit();
Platform.isIntel();
Platform.isARM();

and much more.

If you use Maven just add dependency

<dependency>
 <groupId>net.java.dev.jna</groupId>
 <artifactId>jna</artifactId>
 <version>5.2.0</version>
</dependency>

Otherwise just find jna library jar file (ex. jna-5.2.0.jar) and add it to classpath.

for file in Data/*.txt
do
    for ((i = 0; i < 3; i++))
    do
        name=${file##*/}
        base=${name%.txt}
        ./MyProgram.exe "$file" Logs/"${base}_Log$i.txt"
    done
done

The name=${file##*/} substitution (shell parameter expansion) removes the leading pathname up to the last /.

The base=${name%.txt} substitution removes the trailing .txt. It's a bit trickier if the extensions can vary.

To disable all mouse click

var event = $(document).click(function(e) {
    e.stopPropagation();
    e.preventDefault();
    e.stopImmediatePropagation();
    return false;
});

// disable right click
$(document).bind('contextmenu', function(e) {
    e.stopPropagation();
    e.preventDefault();
    e.stopImmediatePropagation();
    return false;
});

to enable it again:

$(document).unbind('click');
$(document).unbind('contextmenu');

There is not currently any way to style HTML5 <audio> players using CSS. Instead, you can leave off the control attribute, and implement your own controls using Javascript. If you don't want to implement them all on your own, I'd recommend using an existing themeable HTML5 audio player, such as jPlayer.

In my instance, I was running an abnormal query to fix data. If you lock the tables in your query, then you won't have to deal with the Lock timeout:

LOCK TABLES `customer` WRITE;
update customer set account_import_id = 1;
UNLOCK TABLES;

This is probably not a good idea for normal use.

Very Clever and easy way to detect your string is contains only digits or not is this way:

string s = "12fg";

if(s.All(char.IsDigit))
{
   return true; // contains only digits
}
else
{
   return false; // contains not only digits
}

Installing MVC directly on your web server is one option, as then the assemblies will be installed in the GAC. You can also bin deploy the assemblies, which might help keep your server clear of pre-release assemblies until a final release is available.

Phil Haack posted a nice article a couple days ago about how to deploy MVC along with your app, so it's not necessary to install directly:

http://www.haacked.com/archive/2008/11/03/bin-deploy-aspnetmvc.aspx

Note: The following applies to Windows PowerShell.
See the next section for the cross-platform PowerShell Core (v6+) edition.

• On PSv5.1 or higher, where > and >> are effectively aliases of Out-File, you can set the default encoding for > / >> / Out-File via the $PSDefaultParameterValues preference variable:

  • $PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'

• On PSv5.0 or below, you cannot change the encoding for > / >>, but, on PSv3 or higher, the above technique does work for explicit calls to Out-File.
  (The $PSDefaultParameterValues preference variable was introduced in PSv3.0).

• On PSv3.0 or higher, if you want to set the default encoding for all cmdlets that support
  an -Encoding parameter (which in PSv5.1+ includes > and >>), use:

  • $PSDefaultParameterValues['*:Encoding'] = 'utf8'

If you place this command in your $PROFILE, cmdlets such as Out-File and Set-Content will use UTF-8 encoding by default, but note that this makes it a session-global setting that will affect all commands / scripts that do not explicitly specify an encoding via their -Encoding parameter.

Similarly, be sure to include such commands in your scripts or modules that you want to behave the same way, so that they indeed behave the same even when run by another user or a different machine; however, to avoid a session-global change, use the following form to create a local copy of $PSDefaultParameterValues:

• $PSDefaultParameterValues = @{ '*:Encoding' = 'utf8' }

Caveat: PowerShell, as of v5.1, invariably creates UTF-8 files _with a (pseudo) BOM_, which is customary only in the Windows world - Unix-based utilities do not recognize this BOM (see bottom); see this post for workarounds that create BOM-less UTF-8 files.

For a summary of the wildly inconsistent default character encoding behavior across many of the Windows PowerShell standard cmdlets, see the bottom section.

The automatic $OutputEncoding variable is unrelated, and only applies to how PowerShell communicates with external programs (what encoding PowerShell uses when sending strings to them) - it has nothing to do with the encoding that the output redirection operators and PowerShell cmdlets use to save to files.

Optional reading: The cross-platform perspective: PowerShell Core:

PowerShell is now cross-platform, via its PowerShell Core edition, whose encoding - sensibly - defaults to BOM-less UTF-8, in line with Unix-like platforms.

• This means that source-code files without a BOM are assumed to be UTF-8, and using > / Out-File / Set-Content defaults to BOM-less UTF-8; explicit use of the utf8 -Encoding argument too creates BOM-less UTF-8, but you can opt to create files with the pseudo-BOM with the utf8bom value.

• If you create PowerShell scripts with an editor on a Unix-like platform and nowadays even on Windows with cross-platform editors such as Visual Studio Code and Sublime Text, the resulting *.ps1 file will typically not have a UTF-8 pseudo-BOM:

  • This works fine on PowerShell Core.
  • It may break on Windows PowerShell, if the file contains non-ASCII characters; if you do need to use non-ASCII characters in your scripts, save them as UTF-8 with BOM.
    Without the BOM, Windows PowerShell (mis)interprets your script as being encoded in the legacy "ANSI" codepage (determined by the system locale for pre-Unicode applications; e.g., Windows-1252 on US-English systems).

• Conversely, files that do have the UTF-8 pseudo-BOM can be problematic on Unix-like platforms, as they cause Unix utilities such as cat, sed, and awk - and even some editors such as gedit - to pass the pseudo-BOM through, i.e., to treat it as data.

  • This may not always be a problem, but definitely can be, such as when you try to read a file into a string in bash with, say, text=$(cat file) or text=$(<file) - the resulting variable will contain the pseudo-BOM as the first 3 bytes.

Inconsistent default encoding behavior in Windows PowerShell:

Regrettably, the default character encoding used in Windows PowerShell is wildly inconsistent; the cross-platform PowerShell Core edition, as discussed in the previous section, has commendably put and end to this.

Note:

• The following doesn't aspire to cover all standard cmdlets.

• Googling cmdlet names to find their help topics now shows you the PowerShell Core version of the topics by default; use the version drop-down list above the list of topics on the left to switch to a Windows PowerShell version.

• As of this writing, the documentation frequently incorrectly claims that ASCII is the default encoding in Windows PowerShell - see this GitHub docs issue.

Cmdlets that write:

Out-File and > / >> create "Unicode" - UTF-16LE - files by default - in which every ASCII-range character (too) is represented by 2 bytes - which notably differs from Set-Content / Add-Content (see next point); New-ModuleManifest and Export-CliXml also create UTF-16LE files.

Set-Content (and Add-Content if the file doesn't yet exist / is empty) uses ANSI encoding (the encoding specified by the active system locale's ANSI legacy code page, which PowerShell calls Default).

Export-Csv indeed creates ASCII files, as documented, but see the notes re -Append below.

Export-PSSession creates UTF-8 files with BOM by default.

New-Item -Type File -Value currently creates BOM-less(!) UTF-8.

The Send-MailMessage help topic also claims that ASCII encoding is the default - I have not personally verified that claim.

Start-Transcript invariably creates UTF-8 files with BOM, but see the notes re -Append below.

Re commands that append to an existing file:

>> / Out-File -Append make no attempt to match the encoding of a file's existing content. That is, they blindly apply their default encoding, unless instructed otherwise with -Encoding, which is not an option with >> (except indirectly in PSv5.1+, via $PSDefaultParameterValues, as shown above). In short: you must know the encoding of an existing file's content and append using that same encoding.

Add-Content is the laudable exception: in the absence of an explicit -Encoding argument, it detects the existing encoding and automatically applies it to the new content.^{Thanks, js2010}. Note that in Windows PowerShell this means that it is ANSI encoding that is applied if the existing content has no BOM, whereas it is UTF-8 in PowerShell Core.

This inconsistency between Out-File -Append / >> and Add-Content, which also affects PowerShell Core, is discussed in this GitHub issue.

Export-Csv -Append partially matches the existing encoding: it blindly appends UTF-8 if the existing file's encoding is any of ASCII/UTF-8/ANSI, but correctly matches UTF-16LE and UTF-16BE.
To put it differently: in the absence of a BOM, Export-Csv -Append assumes UTF-8 is, whereas Add-Content assumes ANSI.

Start-Transcript -Append partially matches the existing encoding: It correctly matches encodings with BOM, but defaults to potentially lossy ASCII encoding in the absence of one.

Cmdlets that read (that is, the encoding used in the absence of a BOM):

Get-Content and Import-PowerShellDataFile default to ANSI (Default), which is consistent with Set-Content.
ANSI is also what the PowerShell engine itself defaults to when it reads source code from files.

By contrast, Import-Csv, Import-CliXml and Select-String assume UTF-8 in the absence of a BOM.

There are several ways to intercept the initialization process in Spring. If you have to initialize all beans and autowire/inject them there are at least two ways that I know of that will ensure this. I have only testet the second one but I belive both work the same.

If you are using @Bean you can reference by initMethod, like this.

@Configuration
public class BeanConfiguration {

  @Bean(initMethod="init")
  public BeanA beanA() {
    return new BeanA();
  }
}

public class BeanA {

  // method to be initialized after context is ready
  public void init() {
  }

} 

If you are using @Component you can annotate with @EventListener like this.

@Component
public class BeanB {

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
  }
}

In my case I have a legacy system where I am now taking use of IoC/DI where Spring Boot is the choosen framework. The old system brings many circular dependencies to the table and I therefore must use setter-dependency a lot. That gave me some headaches since I could not trust @PostConstruct since autowiring/injection by setter was not yet done. The order is constructor, @PostConstruct then autowired setters. I solved it with @EventListener annotation which wil run last and at the "same" time for all beans. The example shows implementation of InitializingBean aswell.

I have two classes (@Component) with dependency to each other. The classes looks the same for the purpose of this example displaying only one of them.

@Component
public class BeanA implements InitializingBean {
  private BeanB beanB;

  public BeanA() {
    log.debug("Created...");
  }

  @PostConstruct
  private void postConstruct() {
    log.debug("@PostConstruct");
  }

  @Autowired
  public void setBeanB(BeanB beanB) {
    log.debug("@Autowired beanB");
    this.beanB = beanB;
  }

  @Override
  public void afterPropertiesSet() throws Exception {
    log.debug("afterPropertiesSet()");
  }

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
    log.debug("@EventListener");
  } 
}

This is the log output showing the order of the calls when the container starts.

As you can see @EventListener is run last after everything is ready and configured.

This process is somewhat un-orthodox, but would work across all python versions,

Suppose you want to execute a script named 'recommend.py' inside an 'if' condition, then use,

if condition:
       import recommend

The technique is different, but works!

Keep in mind if you are wanting to test this component you will want to inject the window. Use the @Inject() function to inject the window object by naming it using a string token like detailed in this duplicate

I have got the solution for my query:

i have done something like this:

cell.innerHTML="<img height=40 width=40 alt='' src='<%=request.getContextPath()%>/writeImage.htm?' onerror='onImgError(this);' onLoad='setDefaultImage(this);'>"

function setDefaultImage(source){
        var badImg = new Image();
        badImg.src = "video.png";
        var cpyImg = new Image();
        cpyImg.src = source.src;

        if(!cpyImg.width)
        {
            source.src = badImg.src;
        }

    }


    function onImgError(source){
        source.src = "video.png";
        source.onerror = ""; 
        return true; 
    } 

This way it's working in all browsers.

Have you tried setting the li width to, say, 16% with a margin of 0.5%?

nav li {
  line-height: 87px;
  float: left;
  text-align: center;
  width: 16%;
  margin-right: 0.5%;
}

edit: I would set the UL to 100% width:

nav ul { width: 100%; margin: 0 auto; }

I recently needed to do the same thing, and was pleased that the colspan worked fine with consecutive pipes ||

Tested on v4.5 (latest on macports) and the v5.4 (latest on homebrew). Not sure why it doesn't work on the live preview site you provide.

A simple test that I started with was:

| Header ||
|--------------|
| 0 | 1 |

using the command:

multimarkdown -t html test.md > test.html

Your DemoApplication class is in the com.ag.digital.demo.boot package and your LoginBean class is in the com.ag.digital.demo.bean package. By default components (classes annotated with @Component) are found if they are in the same package or a sub-package of your main application class DemoApplication. This means that LoginBean isn't being found so dependency injection fails.

There are a couple of ways to solve your problem:

1. Move LoginBean into com.ag.digital.demo.boot or a sub-package.
2. Configure the packages that are scanned for components using the scanBasePackages attribute of @SpringBootApplication that should be on DemoApplication.

A few of other things that aren't causing a problem, but are not quite right with the code you've posted:

• @Service is a specialisation of @Component so you don't need both on LoginBean
• Similarly, @RestController is a specialisation of @Component so you don't need both on DemoRestController
• DemoRestController is an unusual place for @EnableAutoConfiguration. That annotation is typically found on your main application class (DemoApplication) either directly or via @SpringBootApplication which is a combination of @ComponentScan, @Configuration, and @EnableAutoConfiguration.

I found

dmesg | grep tty

doing the job.

A great way to do this would be to use CSS 3 indeed.

Create a div width a class - e.g. supersizer on top of your page:

Then set following CSS properties:

  .supersizer {_x000D_
    background: url("http://fc06.deviantart.net/fs70/f/2012/099/d/f/stackoverflow_16x16_icon_by_muntoo_stock-d4vl2v4.png") no-repeat center center fixed;_x000D_
    width: 100%;_x000D_
    height: 100%;_x000D_
    position: fixed;_x000D_
    z-index: -1;_x000D_
    opacity: 0.5;_x000D_
    -webkit-background-size: cover;_x000D_
    -moz-background-size: cover;_x000D_
    -o-background-size: cover;_x000D_
    background-size: cover;_x000D_
    top: 0;_x000D_
  }

<div class="supersizer"></div>

As paxdiablo said you can use >& to redirect both stdout and stderr. However if you want them separated you can use the following:

(command > stdoutfile) >& stderrfile

...as indicated the above will redirect stdout to stdoutfile and stderr to stderrfile.

TLDR

=(A1/86400)+25569

...and the format of the cell should be date.

If it doesn't work for you

• If you get a number you forgot to format the output cell as a date.
• If you get ##### you probably don't have a real Unix time. Check your timestamps in https://www.epochconverter.com/. Try to divide your input by 10, 100, 1000 or 10000**
• You work with timestamps outside Excel's (very extended) limits.
• You didn't replace A1 with the cell containing the timestamp ;-p

Explanation

Unix system represent a point in time as a number. Specifically the number of seconds* since a zero-time called the Unix epoch which is 1/1/1970 00:00 UTC/GMT. This number of seconds is called "Unix timestamp" or "Unix time" or "POSIX time" or just "timestamp" and sometimes (confusingly) "Unix epoch".

In the case of Excel they chose a different zero-time and step (because who wouldn't like variety in technical details?). So Excel counts days since 24 hours before 1/1/0000 UTC/GMT. So 25569 corresponds to 1/1/1970 00:00 UTC/GMT and 25570 to 2/1/1970 00:00.

Now please note that we have 86400 seconds per day (24 hours x60 minutes each x60 seconds) and you can understand what this formula does: A1/86400 converts seconds to days and +25569 adjusts for the offset between what is time-zero for Unix and what is time-zero for Excel.

By the way DATE(1970,1,1) will helpfully return 25569 for you in case you forget all this so a more "self-documenting" way to write our formula is:

=A1/(24*60*60) + DATE(1970,1,1)

P.S.: All these were already present in other answers and comments just not laid out as I like them and I don't feel it's OK to edit the hell out of another answer.

*: that's almost correct because you should not count leap seconds

**: E.g. in the case of this question the number was number of milliseconds since the the Unix epoch.

Past 10g the current answer no longer works for renaming views. The only method that still works is dropping and recreating the view. The best way I can think of to do this would be:

SELECT TEXT FROM ALL_VIEWS WHERE owner='some_schema' and VIEW_NAME='some_view';

Add this in front of the SQL returned

Create or replace view some_schema.new_view_name as ...

Drop the old view

Drop view some_schema.some_view;

Try this

string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };

var t = lines.ToList().Find(c => c.Contains(stringToCheck));

It will return you the line with the first incidence of the text that you are looking for.

So, I spent some time with this issue and found a solution. It is not pretty one, but at least a start point - maybe someone will supplement this with some useful comments.

Some info about mapping that I found in process:

• Class that contains basic mapping of Hibernate types to property types is org.hibernate.type.TypeFactory. All this mappings are stored in unmodifiable map

  private static final Map BASIC_TYPES;
  ...
  basics.put( java.util.Date.class.getName(), Hibernate.TIMESTAMP );
  ...
  BASIC_TYPES = Collections.unmodifiableMap( basics );
  

As you can see with java.util.Date type assosited with Hibernate type org.hibernate.type.TimestampType

• Next interesting moment - creation of Hibernate org.hibernate.cfg.Configuration - object that contains all info about mapped classes. This classes and their properties can be extracted like this:

  Iterator clsMappings = cfg.getClassMappings();
  while(clsMappings.hasNext()){
      PersistentClass mapping = (PersistentClass) clsMappings.next();
      handleProperties(mapping.getPropertyIterator(), map);
  }
  

• Vast majority of properties are the objects of org.hibernate.mapping.SimpleValue types. Our point of interest is the method SimpleValue.getType() - in this method is defined what type will be used to convert properties values back-and-forth while working with DB

  Type result = TypeFactory.heuristicType(typeName, typeParameters);
  

At this point I understand that I am unable to modify BASIC_TYPES - so the only way - to replace SimpleValue object to the properties of java.util.Date types to my custom Object that will be able to know the exact type to convert.

The solution:

• Create custom container entity manager factory by extending HibernatePersistence class and overriding its method createContainerEntityManagerFactory:

  public class HibernatePersistenceExtensions extends HibernatePersistence {
  
      @Override
      public EntityManagerFactory createContainerEntityManagerFactory(PersistenceUnitInfo info, Map map) {
  
          if ("true".equals(map.get("hibernate.use.custom.entity.manager.factory"))) {
              return CustomeEntityManagerFactoryFactory.createCustomEntityManagerFactory(info, map);
          } else {
              return super.createContainerEntityManagerFactory(info, map);
          }
      }
  }
  

• Create Hibernate configuration object, modify value ojects for java.util.Date properties and then create custom entity manager factory.

  public class ReattachingEntityManagerFactoryFactory {
  
  
      @SuppressWarnings("rawtypes")
      public static EntityManagerFactory createContainerEntityManagerFactory(
      PersistenceUnitInfo info, Map map) {
          Ejb3Configuration cfg = new Ejb3Configuration();
  
          Ejb3Configuration configured = cfg.configure( info, map );
  
          handleClassMappings(cfg, map);
  
          return configured != null ? configured.buildEntityManagerFactory() : null;
      }
  
      @SuppressWarnings("rawtypes")
      private static void handleClassMappings(Ejb3Configuration cfg, Map map) {
          Iterator clsMappings = cfg.getClassMappings();
          while(clsMappings.hasNext()){
               PersistentClass mapping = (PersistentClass) clsMappings.next();
               handleProperties(mapping.getPropertyIterator(), map);
          }
      } 
  
  
  
      private static void handleProperties(Iterator props, Map map) {
  
          while(props.hasNext()){
               Property prop = (Property) props.next();
               Value value = prop.getValue();
               if (value instanceof Component) {
                   Component c = (Component) value;
                   handleProperties(c.getPropertyIterator(), map);
               } else {
  
                   handleReturnUtilDateInsteadOfTimestamp(prop, map);
  
               }
           }
  
      private static void handleReturnUtilDateInsteadOfTimestamp(Property prop, Map map) {
          if ("true".equals(map.get("hibernate.return.date.instead.of.timestamp"))) {
              Value value = prop.getValue();
  
              if (value instanceof SimpleValue) {
                  SimpleValue simpleValue = (SimpleValue) value;
                  String typeName = simpleValue.getTypeName();
                  if ("java.util.Date".equals(typeName)) {
                      UtilDateSimpleValue udsv = new UtilDateSimpleValue(simpleValue);
                      prop.setValue(udsv);
                  }
              }
          }
      }
  
  }
  

As you can see I just iterate over every property and substitute SimpleValue-object for UtilDateSimpleValue for properties of type java.util.Date. This is very simple class - it implements the same interface as SimpleValue object, e.g org.hibernate.mapping.KeyValue. In constructor original SimpleValue object is passed - so every call to UtilDateSimpleValue is redirected to the original object with one exception - method getType(...) return my custom Type.

public class UtilDateSimpleValue implements KeyValue{

    private SimpleValue value;

    public UtilDateSimpleValue(SimpleValue value) {
        this.value = value;
    }

    public SimpleValue getValue() {
        return value;
    }

    @Override
    public int getColumnSpan() {
        return value.getColumnSpan();
    }

    ...

    @Override
    public Type getType() throws MappingException {
        final String typeName = value.getTypeName();

        if (typeName == null) {
                throw new MappingException("No type name");
        }

        Type result = new UtilDateUserType();

        return result;
    }
    ...
}

• And the last step is implementation of UtilDateUserType. I just extend original org.hibernate.type.TimestampType and override its method get() like this:

  public class UtilDateUserType extends TimestampType{
  
      @Override
      public Object get(ResultSet rs, String name) throws SQLException {
          Timestamp ts = rs.getTimestamp(name);
  
          Date result = null;
          if(ts != null){
              result = new Date(ts.getTime());
          }
  
          return result;
      }
  }
  

That is all. A little bit tricky, but now every java.util.Date property is returned as java.util.Date without any additional modifications of existing code (annotations or modifying setters). As I find out in Hibernate 4 or above there is a much more easier way to substitute your own type (see details here: Hibernate TypeResolver). Any suggestions or criticism are welcome.

I know this comes in late, but why not use plain JS to remove the event?

var myElement = document.getElementById("your_ID");
myElement.onclick = null;

or, if you use a named function as an event handler:

function eh(event){...}
var myElement = document.getElementById("your_ID");
myElement.addEventListener("click",eh); // add event handler
myElement.removeEventListener("click",eh); //remove it

Try to do...

Vanilla Javascipt does not support multi-line strings. Language pre-processors are turning out to be feasable these days.

CoffeeScript, the most popular of these has this feature, but it's not minimal, it's a new language. Google's traceur compiler adds new features to the language as a superset, but I don't think multi-line strings are one of the added features.

I'm looking to make a minimal superset of javascript that supports multiline strings and a couple other features. I started this little language a while back before writing the initial compiler for coffeescript. I plan to finish it this summer.

If pre-compilers aren't an option, there is also the script tag hack where you store your multi-line data in a script tag in the html, but give it a custom type so that it doesn't get evaled. Then later using javascript, you can extract the contents of the script tag.

Also, if you put a \ at the end of any line in source code, it will cause the the newline to be ignored as if it wasn't there. If you want the newline, then you have to end the line with "\n\".

with open("myfile.txt") as f:
    lines = f.readlines()
    first_row = lines[0]
    print first_row
    last_row = lines[-1]
    print last_row

To make the whole div act as a link, set the anchor tag as:

display: block

And set your height of the anchor tag to 100%. Then set a fixed height to your div tag. Then style your anchor tag like usual.

For example:

<html>
<head>
    <title>DIV Link</title>

    <style type="text/css">
    .link-container {
        border: 1px solid;
        width: 50%;
        height: 20px;
    }

    .link-container a {
        display: block;
        background: #c8c8c8;
        height: 100%;
        text-align: center;
    }

    .link-container a:hover {
        background: #f8f8f8;
    }

    </style>

</head>
<body>

    <div class="link-container">
        <a href="http://www.stackoverflow.com">Stack Overflow</a>
    </div>

    <div class="link-container">
        <a href="http://www.stackoverflow.com">Stack Overflow</a>
    </div>

</body> </html>

Good luck!

You have to create either another page or generic handler with the code to generate your pdf. Then that event gets triggered and the person is redirected to that page.

You need to use == or === for comparison. = assigns a new value.

Besides that, using == is pointless when dealing with booleans only. Just use if(foo) instead of if(foo == true).

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 26
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

This will do it for you:

function inArray(needle, haystack) {
    var length = haystack.length;
    for(var i = 0; i < length; i++) {
        if(haystack[i] == needle)
            return true;
    }
    return false;
}

I found it in Stack Overflow question JavaScript equivalent of PHP's in_array().

You can use this code:

<select id="menu" name="links" size="1" onchange="window.location.href=this.value;">
    <option value="URL">Book</option>
    <option value="URL">Pen</option>
    <option value="URL">Read</option>
    <option value="URL">Apple</option>
</select>

To check that the file you're trying to open actually exists, you can change directories in terminal using cd. To change to ~/Desktop/sass/css: cd ~/Desktop/sass/css. To see what files are in the directory: ls.

If you want information about either of those commands, use the man page: man cd or man ls, for example.

Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.

On Mac OS X, you can also use open to open a finder window: open . will open the current directory in finder. (open ~/Desktop/sass/css will open the ~/Desktop/sass/css).

For Python Run This Command

apt-get install -y python-setuptools

For Python 3.

apt-get install -y python3-setuptools

On RHEL 6 this worked for me also:

umount -f -a -t cifs -l FOLDER_NAME

I asked a question about this and I was referred to this post with the message:

This question already has an answer here:

“Notice: Undefined variable”, “Notice: Undefined index”, and “Notice: Undefined offset” using PHP

I am sharing my question and solution here:

This is the error:

Line 154 is the problem. This is what I have in line 154:

153    foreach($cities as $key => $city){
154        if(($city != 'London') && ($city != 'Madrid') && ($citiesCounterArray[$key] >= 1)){

I think the problem is that I am writing if conditions for the variable $city, which is not the key but the value in $key => $city. First, could you confirm if that is the cause of the warning? Second, if that is the problem, why is it that I cannot write a condition based on the value? Does it have to be with the key that I need to write the condition?

UPDATE 1: The problem is that when executing $citiesCounterArray[$key], sometimes the $key corresponds to a key that does not exist in the $citiesCounterArray array, but that is not always the case based on the data of my loop. What I need is to set a condition so that if $key exists in the array, then run the code, otherwise, skip it.

UPDATE 2: This is how I fixed it by using array_key_exists():

foreach($cities as $key => $city){
    if(array_key_exists($key, $citiesCounterArray)){
        if(($city != 'London') && ($city != 'Madrid') && ($citiesCounterArray[$key] >= 1)){

Combining the input from everyone else (use not, no parens, use os.mkdir) you'd get...

special_path_for_john = "/usr/share/sounds/blues"
if not os.path.exists(special_path_for_john):
    os.mkdir(special_path_for_john)

The formtarget attribute is only used for buttons with type="submit".

That is from this reference.

Here is an answer using JavaScript:

<input type="button" onClick="openNewTab()" value="facebook">

<script type="text/javascript">
    function openNewTab() {
        window.open("http://www.facebook.com/");
    }
</script>

Note: This is some explanation and pseudocode as to how to implement a very trivial server that can handle incoming and outcoming WebSocket messages as per the definitive framing format. It does not include the handshaking process. Furthermore, this answer has been made for educational purposes; it is not a full-featured implementation.

Specification (RFC 6455)

Sending messages

(In other words, server → browser)

The frames you're sending need to be formatted according to the WebSocket framing format. For sending messages, this format is as follows:

• one byte which contains the type of data (and some additional info which is out of scope for a trivial server)
• one byte which contains the length
• either two or eight bytes if the length does not fit in the second byte (the second byte is then a code saying how many bytes are used for the length)
• the actual (raw) data

The first byte will be 1000 0001 (or 129) for a text frame.

The second byte has its first bit set to 0 because we're not encoding the data (encoding from server to client is not mandatory).

It is necessary to determine the length of the raw data so as to send the length bytes correctly:

• if 0 <= length <= 125, you don't need additional bytes
• if 126 <= length <= 65535, you need two additional bytes and the second byte is 126
• if length >= 65536, you need eight additional bytes, and the second byte is 127

The length has to be sliced into separate bytes, which means you'll need to bit-shift to the right (with an amount of eight bits), and then only retain the last eight bits by doing AND 1111 1111 (which is 255).

After the length byte(s) comes the raw data.

This leads to the following pseudocode:

bytesFormatted[0] = 129

indexStartRawData = -1 // it doesn't matter what value is
                       // set here - it will be set now:

if bytesRaw.length <= 125
    bytesFormatted[1] = bytesRaw.length

    indexStartRawData = 2

else if bytesRaw.length >= 126 and bytesRaw.length <= 65535
    bytesFormatted[1] = 126
    bytesFormatted[2] = ( bytesRaw.length >> 8 ) AND 255
    bytesFormatted[3] = ( bytesRaw.length      ) AND 255

    indexStartRawData = 4

else
    bytesFormatted[1] = 127
    bytesFormatted[2] = ( bytesRaw.length >> 56 ) AND 255
    bytesFormatted[3] = ( bytesRaw.length >> 48 ) AND 255
    bytesFormatted[4] = ( bytesRaw.length >> 40 ) AND 255
    bytesFormatted[5] = ( bytesRaw.length >> 32 ) AND 255
    bytesFormatted[6] = ( bytesRaw.length >> 24 ) AND 255
    bytesFormatted[7] = ( bytesRaw.length >> 16 ) AND 255
    bytesFormatted[8] = ( bytesRaw.length >>  8 ) AND 255
    bytesFormatted[9] = ( bytesRaw.length       ) AND 255

    indexStartRawData = 10

// put raw data at the correct index
bytesFormatted.put(bytesRaw, indexStartRawData)


// now send bytesFormatted (e.g. write it to the socket stream)

Receiving messages

(In other words, browser → server)

The frames you obtain are in the following format:

• one byte which contains the type of data
• one byte which contains the length
• either two or eight additional bytes if the length did not fit in the second byte
• four bytes which are the masks (= decoding keys)
• the actual data

The first byte usually does not matter - if you're just sending text you are only using the text type. It will be 1000 0001 (or 129) in that case.

The second byte and the additional two or eight bytes need some parsing, because you need to know how many bytes are used for the length (you need to know where the real data starts). The length itself is usually not necessary since you have the data already.

The first bit of the second byte is always 1 which means the data is masked (= encoded). Messages from the client to the server are always masked. You need to remove that first bit by doing secondByte AND 0111 1111. There are two cases in which the resulting byte does not represent the length because it did not fit in the second byte:

• a second byte of 0111 1110, or 126, means the following two bytes are used for the length
• a second byte of 0111 1111, or 127, means the following eight bytes are used for the length

The four mask bytes are used for decoding the actual data that has been sent. The algorithm for decoding is as follows:

decodedByte = encodedByte XOR masks[encodedByteIndex MOD 4]

where encodedByte is the original byte in the data, encodedByteIndex is the index (offset) of the byte counting from the first byte of the real data, which has index 0. masks is an array containing of the four mask bytes.

This leads to the following pseudocode for decoding:

secondByte = bytes[1]

length = secondByte AND 127 // may not be the actual length in the two special cases

indexFirstMask = 2          // if not a special case

if length == 126            // if a special case, change indexFirstMask
    indexFirstMask = 4

else if length == 127       // ditto
    indexFirstMask = 10

masks = bytes.slice(indexFirstMask, 4) // four bytes starting from indexFirstMask

indexFirstDataByte = indexFirstMask + 4 // four bytes further

decoded = new array

decoded.length = bytes.length - indexFirstDataByte // length of real data

for i = indexFirstDataByte, j = 0; i < bytes.length; i++, j++
    decoded[j] = bytes[i] XOR masks[j MOD 4]


// now use "decoded" to interpret the received data

List is an interface. You need a specific class in the end so either try

List l = new ArrayList();

or

List l = new LinkedList();

Whichever suit your needs.

Try this:

Date date=new Date("12/12/11 8:22:09 PM");    
System.out.println("Time in 24Hours ="+new SimpleDateFormat("HH:mm").format(date));

Another way to handle the situation is exception handling.

Every time a non-existent value is called, your code will recover from the exception and just continue with the loop. In the catch-block you can handle the error the same way you write it down in your else-statement when the expression (... != null) returns false. Of course throwing and handling exceptions is a relatively costly operation which might not be ideal depending on the performance requirements.

Did you check the string concatenation function? Something like:

update table_c set column_a = column_b || column_c 

should work. More here

For multiple way points, following can be used as well.

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
    Uri.parse("https://www.google.com/maps/dir/48.8276261,2.3350114/48.8476794,2.340595/48.8550395,2.300022/48.8417122,2.3028844"));
startActivity(intent);

First set of coordinates are your starting location. All of the next are way points, plotted route goes through.

Just keep adding way points by concating "/latitude,longitude" at the end. There is apparently a limit of 23 way points according to google docs. Not sure if that applies to Android too.

After calculation of the boundries you can check the distance between upper left and down right corner; then you can understand the zoom level by testing the distance (if distance is too far zoom level would be low) then you can select wheter using setbound method or setZoom..

Hardware

I'm sorry, but upgrading development station to SSD and tons of ram has probably a bigger influence than points below combined.

Tools versions

Increasing build performance has major priority for the development teams, so make sure you are using latest Gradle and Android Gradle Plugin.

Configuration File

Create a file named gradle.properties in whatever directory applies:

• /home/<username>/.gradle/ (Linux)
• /Users/<username>/.gradle/ (Mac)
• C:\Users\<username>\.gradle (Windows)

Append:

# IDE (e.g. Android Studio) users:
# Settings specified in this file will override any Gradle settings
# configured through the IDE.

# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html

# The Gradle daemon aims to improve the startup and execution time of Gradle.
# When set to true the Gradle daemon is to run the build.
# TODO: disable daemon on CI, since builds should be clean and reliable on servers
org.gradle.daemon=true

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# https://medium.com/google-developers/faster-android-studio-builds-with-dex-in-process-5988ed8aa37e#.krd1mm27v
org.gradle.jvmargs=-Xmx5120m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit

org.gradle.parallel=true

# Enables new incubating mode that makes Gradle selective when configuring projects. 
# Only relevant projects are configured which results in faster builds for large multi-projects.
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
org.gradle.configureondemand=true

# http://tools.android.com/tech-docs/build-cache
android.enableBuildCache=true

Gradle properties works local if you place them at projectRoot\gradle.properties and globally if you place them at user_home\.gradle\gradle.properties. Properties applied if you run gradle tasks from console or directly from idea:

IDE Settings

It is possible to tweak Gradle-IntelliJ integration from the IDE settings GUI. Enabling "offline work" (check answer from yava below) will disable real network requests on every "sync gradle file".

Native multi-dex

One of the slowest steps of the apk build is converting java bytecode into single dex file. Enabling native multidex (minSdk 21 for debug builds only) will help the tooling to reduce an amount of work (check answer from Aksel Willgert below).

Dependencies

Prefer @aar dependencies over library sub-projects.

Search aar package on mavenCentral, jCenter or use jitpack.io to build any library from github. If you are not editing sources of the dependency library you should not build it every time with your project sources.

Antivirus

Consider to exclude project and cache files from antivirus scanning. This is obviously a trade off with security (don't try this at home!). But if you switch between branches a lot, then antivirus will rescan files before allowing gradle process to use it, which slows build time (in particular AndroidStudio sync project with gradle files and indexing tasks). Measure build time and process CPU with and without antivirus enabled to see if it is related.

Profiling a build

Gradle has built-in support for profiling projects. Different projects are using a different combination of plugins and custom scripts. Using --profile will help to find bottlenecks.

Two possibilities here. Java Version incompatible or import

Yes, sql can do this, but with a different syntax. The sqlite documentation is pretty good, by the way. It will also tell you that the only way to insert several row is use a select statement as the source of the data to be inserted.

If you are facing any issues during push ( in windows OS), just remove the cached git account by following the given steps below: 1. Search for Control panel and open the same. 2. Search for Credential Manager and open this. 3. Click on Windows Credentials under Manage your credentials page. 4. Under Generic Credentials click on GitHub. 5. Click on Remove and then confirm by clicking Yes button. 6. Now start pushing the code and you will get GitHub popup to login again and now you are done. Everything will work properly after successful login.

After my question resulted in no satisfying result (because C++ doesn't implement tag-based init for structures), I took the trick I found here: Are members of a C++ struct initialized to 0 by default?

For you it would amount to do that:

address temp_address = {}; // will zero all fields in C++
temp_address.city = "Hamilton";
temp_address.prov = "Ontario";

This is certainly the closest to what you wanted originally (zero all the fields except those you want to initialize).
