Since Java 5, you can use java.util.concurrent.TimeUnit to avoid the use of Magic Numbers like 1000 and 60 in your code.

By the way, you should take care to leap seconds in your computation: the last minute of a year may have an additional leap second so it indeed lasts 61 seconds instead of expected 60 seconds. The ISO specification even plan for possibly 61 seconds. You can find detail in java.util.Date javadoc.

To calculate MD5 hash of CLOB content field with my desired encoding without implicitly recoding content to AL32UTF8, I've used this code:

create or replace function clob2blob(AClob CLOB) return BLOB is
  Result BLOB;
  o1 integer;
  o2 integer;
  c integer;
  w integer;
begin
  o1 := 1;
  o2 := 1;
  c := 0;
  w := 0;
  DBMS_LOB.CreateTemporary(Result, true);
  DBMS_LOB.ConvertToBlob(Result, AClob, length(AClob), o1, o2, 0, c, w);
  return(Result);
end clob2blob;
/

update my_table t set t.hash = (rawtohex(DBMS_CRYPTO.Hash(clob2blob(t.content),2)));

The error you're getting is that self.adj doesn't already have a key 0. You're trying to append to a list that doesn't exist yet.

Consider using a defaultdict instead, replacing this line (in __init__):

self.adj = {}

with this:

self.adj = defaultdict(list)

You'll need to import at the top:

from collections import defaultdict

Now rather than raise a KeyError, self.adj[0].append(edge) will create a list automatically to append to.

For me the solution was to fix the output directory under project settings. Before I was using just "target" for the Project compiler output. Instead I updated it to have a full path e.g. D:\dev\sigplusjava2_68\target

This is an example that works on the AWS Cloud. The scenario is that some machine that booted from autoscaling needs to perform some action on another server, passing the newly spawned instance DNS via SSH

# Get the public DNS of the current machine (AWS specific)
MY_DNS=`curl -s http://169.254.169.254/latest/meta-data/public-hostname`


ssh \
    -o StrictHostKeyChecking=no \
    -i ~/.ssh/id_rsa \

<< EOF
cd ~/
echo "Hey I was just SSHed by ${MY_DNS}"

# Newline is important before final EOF!

If you are using rails or at less activesupport you got String#remove and String#remove! method

Fun new approach to "one-lining" the case of an anonymously split thing such that you don't split it twice, but do all the work in one line is using the walrus operator, :=, to perform assignment as an expression, allowing both:

first, last = (split_str := a.split("-"))[0], split_str[-1]

and:

first, last = (split_str := a.split("-"))[::len(split_str)-1]

Mind you, in both cases it's essentially exactly equivalent to doing on one line:

split_str = a.split("-")

then following up with one of:

first, last = split_str[0], split_str[-1]
first, last = split_str[::len(split_str)-1]

including the fact that split_str persists beyond the line it was used and accessed on. It's just technically meeting the requirements of one-lining, while being fairly ugly. I'd never recommend it over unpacking or itemgetter solutions, even if one-lining was mandatory (ruling out the non-walrus versions that explicitly index or slice a named variable and must refer to said named variable twice).

To follow up on Rachel's answer.
Here's two ways in which you can get Mouse Screen Coordinates in WPF.

1.Using Windows Forms. Add a reference to System.Windows.Forms

public static Point GetMousePositionWindowsForms()
{
    var point = Control.MousePosition;
    return new Point(point.X, point.Y);
}

2.Using Win32

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
internal static extern bool GetCursorPos(ref Win32Point pt);

[StructLayout(LayoutKind.Sequential)]
internal struct Win32Point
{
    public Int32 X;
    public Int32 Y;
};
public static Point GetMousePosition()
{
    var w32Mouse = new Win32Point();
    GetCursorPos(ref w32Mouse);

    return new Point(w32Mouse.X, w32Mouse.Y);
}

It suppresses errors.

See Error Control Operators in the manual:

PHP supports one error control operator: the at sign (@). When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.

If you have set a custom error handler function with set_error_handler() then it will still get called, but this custom error handler can (and should) call error_reporting() which will return 0 when the call that triggered the error was preceded by an @...

Assuming that your branch was created off of master, then while in the branch (that is, you have the branch checked out):

git cherry -v master

or

git log master..

If you are not in the branch, then you can add the branch name to the "git log" command, like this:

git log master..branchname

If your branch was made off of origin/master, then say origin/master instead of master.

There are a couple of things to check:

• In FireBug, see if there are any loading errors that would indicate that your script is badly formatted and the functions do not get registered.
• You can also try typing "proceedToSecond" into the FireBug console to see if the function gets defined
• One thing you may try is removing the space around the @type attribute to the script tag: it should be <script type="text/javascript"> instead of <script type = "text/javascript">

If supported by your browser, you may use CSS3 :read-only selector:

input[type="text"]:read-only {
    cursor: normal;
    background-color: #f8f8f8;
    color: #999;
}

I had a slightly different requirement, whereby I had to selectively transpose columns into rows.

The table had columns:

create table tbl (ID, PreviousX, PreviousY, CurrentX, CurrentY)

I needed columns for Previous and Current, and rows for X and Y. A Cartesian product generated on a static table worked nicely, eg:

select 
    ID,
    max(case when metric='X' then PreviousX
        case when metric='Y' then PreviousY end) as Previous,
    max(case when metric='X' then CurrentX
        case when metric='Y' then CurrentY end) as Current
from tbl inner join
    /* Cartesian product - transpose by repeating row and 
    picking appropriate metric column for period */
    ( VALUES (1, 'X'), (2, 'Y')) AS x (sort, metric) ON 1=1
group by ID
order by ID, sort

Running .html files as php stopped working all of a sudden in my .htaccess file.

well, using the Macro record, and doing it manually, I ended up with this code .. which seems to work .. (although it's not a one liner like yours ;)

lrow = Selection.Row()
Rows(lrow).Select
Selection.Copy
Rows(lrow + 1).Select
Selection.Insert Shift:=xlDown
Application.CutCopyMode = False
Selection.ClearContents

(I put the ClearContents in there because you indicated you wanted format, and I'm assuming you didn't want the data ;) )

If you're finding by Contains then it'll be like this

    $("input[id*='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Starts With then it'll be like this

    $("input[id^='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Ends With then it'll be like this

     $("input[id$='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is not a given string

    $("input[id!='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which name contains a given word, delimited by spaces

     $("input[name~='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is equal to a given string or starting with that string followed by a hyphen

     $("input[id|='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

Here is a good resource straight from Google: http://developer.android.com/training/basics/firstapp/starting-activity.html

At developer.android.com, they have numerous tutorials explaining just about everything you need to know about android. They even provide detailed API for each class.

If that doesn't help, there are NUMEROUS different resources that can help you with this question and other android questions.

The OP added in his question:

the files checked out using msysgit are using CR+LF and I want to force msysgit to get them with LF

A first simple step would still be in a .gitattributes file:

# 2010
*.txt -crlf

# 2020
*.txt text eol=lf 

(as noted in the comments by grandchild, referring to .gitattributes End-of-line conversion), to avoid any CRLF conversion for files with correct eol.

And I have always recommended git config --global core.autocrlf false to disable any conversion (which would apply to all versioned files)

See Best practices for cross platform git config?

Since Git 2.16 (Q1 2018), you can use git add --renormalize . to apply those .gitattributes settings immediately.

But a second more powerful step involves a gitattribute filter driver and add a smudge step

Whenever you would update your working tree, a script could, only for the files you have specified in the .gitattributes, force the LF eol and any other formatting option you want to enforce.
If the "clear" script doesn't do anything, you will have (after commit) transformed your files, applying exactly the format you need them to follow.

The default values for minOccurs and maxOccurs are 1. Thus:

<xsd:element minOccurs="1" name="asdf"/>

cardinality is [1-1] Note: if you specify only minOccurs attribute, it can't be greater than 1, because the default value for maxOccurs is 1.

<xsd:element minOccurs="5" maxOccurs="2" name="asdf"/>

invalid

<xsd:element maxOccurs="2" name="asdf"/>

cardinality is [1-2] Note: if you specify only maxOccurs attribute, it can't be smaller than 1, because the default value for minOccurs is 1.

<xsd:element minOccurs="0" maxOccurs="0"/>

is a valid combination which makes the element prohibited.

I have a sample

import * as types from '../../helpers/ActionTypes';

var initialState = {
  changedValues: {}
};
const quickEdit = (state = initialState, action) => {

  switch (action.type) {

    case types.PRODUCT_QUICKEDIT:
      {
        const item = action.item;
        const changedValues = {
          ...state.changedValues,
          [item.id]: item,
        };

        return {
          ...state,
          loading: true,
          changedValues: changedValues,
        };
      }
    default:
      {
        return state;
      }
  }
};

export default quickEdit;

If you know the width of the span you could just stuff in a left margin.

Try this:

.center { text-align: center}
div.center span { display: table; }

Add the "center: class to your .

If you want some spans centered, but not others, replace the "div.center span" in your style sheet to a class (e.g "center-span") and add that class to the span.

You can completely handle it in the MySQL query:

SELECT SUM(column_name) FROM table_name;

Using PDO (mysql_query is deprecated)

$stmt = $handler->prepare('SELECT SUM(value) AS value_sum FROM codes');
$stmt->execute();

$row = $stmt->fetch(PDO::FETCH_ASSOC);
$sum = $row['value_sum'];

Or using mysqli:

$result = mysqli_query($conn, 'SELECT SUM(value) AS value_sum FROM codes'); 
$row = mysqli_fetch_assoc($result); 
$sum = $row['value_sum'];

Here is a working exemple :

printf("-%s-", (char[2]){'A', 0});

This will display -A-

The term 'slug' comes from the world of newspaper production.

It's an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the "printing presses", this is the name it is referenced by, e.g., "Have you fixed those errors in the 'kate-and-william' story?".

Some systems (such as Django) use the slug as part of the URL to locate the story, an example being www.mysite.com/archives/kate-and-william.

Even Stack Overflow itself does this, with the GEB-ish^(a) self-referential https://stackoverflow.com/questions/427102/what-is-a-slug-in-django/427201#427201, although you can replace the slug with blahblah and it will still find it okay.

It may even date back earlier than that, since screenplays had "slug lines" at the start of each scene, which basically sets the background for that scene (where, when, and so on). It's very similar in that it's a precis or preamble of what follows.

On a Linotype machine, a slug was a single line piece of metal which was created from the individual letter forms. By making a single slug for the whole line, this greatly improved on the old character-by-character compositing.

Although the following is pure conjecture, an early meaning of slug was for a counterfeit coin (which would have to be pressed somehow). I could envisage that usage being transformed to the printing term (since the slug had to be pressed using the original characters) and from there, changing from the 'piece of metal' definition to the 'story summary' definition. From there, it's a short step from proper printing to the online world.

My opinion is that selectedIndex or using objectAtIndex is not necessarily the best way to switch the tab. If you reorder your tabs, a hard coded index selection might mess with your former app behavior.

If you have the object reference of the view controller you want to switch to, you can do:

tabBarController.selectedViewController = myViewController

Of course you must make sure, that myViewController really is in the list of tabBarController.viewControllers.

You use:

yourcommand  > /dev/null 2>&1

If it should run in the Background add an &

yourcommand > /dev/null 2>&1 &

>/dev/null 2>&1 means redirect stdout to /dev/null AND stderr to the place where stdout points at that time

If you want stderr to occur on console and only stdout going to /dev/null you can use:

yourcommand 2>&1 > /dev/null

In this case stderr is redirected to stdout (e.g. your console) and afterwards the original stdout is redirected to /dev/null

If the program should not terminate you can use:

nohup yourcommand &

Without any parameter all output lands in nohup.out

Virtual Box gives a lot of issues when it comes to bridge adaptor. I had the same issue with Virtual Box for windows 10. I decided to create VirtualBox Host-Only Ethernet adapter. But I again got issues while creating the host-only ethernet adaptor. I decided to switch to vmware. Vmware did not give me any issues. After installing vmware (and after changing few settings in the BIOS) and installing ubuntu on it, it automatically connected to my host machine's internet. It was able to generate it's own IP address as well and could also ping the host machine (windows machine). Hence, for me virtual box created a lot of issues whereas, vmware worked smoothly for me.

No there is no such extension method overload for this. I've found this frustrating myself in the past and as such I usually write a helper class to deal with this problem. The goal is to convert a Func<T,T,bool> to IEqualityComparer<T,T>.

Example

public class EqualityFactory {
  private sealed class Impl<T> : IEqualityComparer<T,T> {
    private Func<T,T,bool> m_del;
    private IEqualityComparer<T> m_comp;
    public Impl(Func<T,T,bool> del) { 
      m_del = del;
      m_comp = EqualityComparer<T>.Default;
    }
    public bool Equals(T left, T right) {
      return m_del(left, right);
    } 
    public int GetHashCode(T value) {
      return m_comp.GetHashCode(value);
    }
  }
  public static IEqualityComparer<T,T> Create<T>(Func<T,T,bool> del) {
    return new Impl<T>(del);
  }
}

This allows you to write the following

var distinctValues = myCustomerList
  .Distinct(EqualityFactory.Create((c1, c2) => c1.CustomerId == c2.CustomerId));

Try adding this to your source:

debugger;

It works in most, if not all browsers. Just place it somewhere in your code, and it will act like a breakpoint.

Due to PEP-0469 which renamed iteritems() to items() and PEP-3113 which removed Tuple parameter unpacking, in Python 3.x you should write Martijn Pieters? answer like this:

my_dictionary = dict(map(lambda item: (item[0], f(item[1])), my_dictionary.items()))

Floating Placeholder

It's simple, safe and reliable to position a placeholder label above a text view, set its font, color and manage placeholder visibility by tracking changes to the text view's character count.

Swift 3:

class NotesViewController : UIViewController, UITextViewDelegate {

    @IBOutlet var textView : UITextView!
    var placeholderLabel : UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()

        textView.delegate = self
        placeholderLabel = UILabel()
        placeholderLabel.text = "Enter some text..."
        placeholderLabel.font = UIFont.italicSystemFont(ofSize: (textView.font?.pointSize)!)
        placeholderLabel.sizeToFit()
        textView.addSubview(placeholderLabel)
        placeholderLabel.frame.origin = CGPoint(x: 5, y: (textView.font?.pointSize)! / 2)
        placeholderLabel.textColor = UIColor.lightGray
        placeholderLabel.isHidden = !textView.text.isEmpty
    }

    func textViewDidChange(_ textView: UITextView) {
        placeholderLabel.isHidden = !textView.text.isEmpty
    }
}

^{Swift 2: Same, except:italicSystemFontOfSize(textView.font.pointSize), UIColor.lightGrayColor}

Just write what you really wanted to know:

fac.GetCachedValue("Auto Print Clinical Warnings").ToLower().StartsWith("y")

It's much simpler than anything with substring.

In Python 3,

def filter_nonprintable(text):
    import itertools
    # Use characters of control category
    nonprintable = itertools.chain(range(0x00,0x20),range(0x7f,0xa0))
    # Use translate to remove all non-printable characters
    return text.translate({character:None for character in nonprintable})

See this StackOverflow post on removing punctuation for how .translate() compares to regex & .replace()

The ranges can be generated via nonprintable = (ord(c) for c in (chr(i) for i in range(sys.maxunicode)) if unicodedata.category(c)=='Cc') using the Unicode character database categories as shown by @Ants Aasma.

If file is in use FileOutputStream fileOutputStream = new FileOutputStream(file); returns java.io.FileNotFoundException with 'The process cannot access the file because it is being used by another process' in the exception message.

just add different .gitignore files to mini project 1 and mini project 2. Each of the .gitignore files should /node_modules and you're good to go.

$x = $y ?? 'dev'

is short hand for x = y if y is set, otherwise x = 'dev'

There is also

$x = $y =="SOMETHING" ? 10 : 20

meaning if y equals 'SOMETHING' then x = 10, otherwise x = 20

paste your .html file in assets folder of your project folder. and create an xml file in layout folder with the fol code: my.xml:

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/webview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
    />

add fol code in activity

setContentView(R.layout.my);
    WebView mWebView = null;
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.loadUrl("file:///android_asset/new.html"); //new.html is html file name.

Mostly this is related to problems on windows with the unzipping it seems. (See other answers here for that).

The second largest issue seems to be that eclipse is not able to find java or finds a java version which is too old or even older eclipse installations.

Here's another take to the latter problem and a small twist to solve it. My work environment is on a linux system, without root access, and with software installations where I can configure which versions to use in a kind of config file. However I have no influence on the way those software packages are installed and they are immutable to me.

I download and untar the latest eclipse as usual to a user disk for which I have write permissions. Then I configure myself an alias to always temporarily cd into the eclipse installation when starting. That regardless of where I work on the file systems, eclipse always finds its correct libraries. It seems in some places, eclipses default search path for java digs out an installation (of java or older eclipses or sth else) in my environment that it really should not use.

Here's the alias: alias eclipse '(pushd /enter_path_to_eclipse_install_dir_here/eclipse ; ./eclipse ; popd)'

Now you can start it normally from e.g. your project or arbitrary work directory:

eclipse

Or also put it in the background

eclipse &

Maybe this helps for people in convoluted work environments.

$("a[href*='id=ABC']").addClass('active_jquery_menu');

Try sending the UTF-8 Charset header:

<?php header ('Content-type: text/html; charset=utf-8'); ?>

And the HTML meta:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

The pythonic way of doing this is using subprocess.Popen

subprocess.Popen takes a list where the first element is the command to be run followed by any command line arguments.

As an example:

import subprocess

args = ['echo', 'Hello!']
subprocess.Popen(args) // same as running `echo Hello!` on cmd line

args2 = ['echo', '-v', '"Hello Again"']
subprocess.Popen(args2) // same as running 'echo -v "Hello Again!"` on cmd line

this worked fine for me:

class ItemSerializer(serializers.ModelSerializer):
    category_name = serializers.ReadOnlyField(source='category.name')
    class Meta:
        model = Item
        fields = "__all__"

using : New Java 7 NIO library, try

        if(!Files.exists(filePath.getParent())) {
            Files.createDirectory(filePath.getParent());
        }
        if(!Files.exists(filePath)) {
            Files.createFile(filePath);
        }
        // Empty the file content
        writer = Files.newBufferedWriter(filePath);
        writer.write("");
        writer.flush();

The above code checks if Directoty exist if not creates the directory, checks if file exists is yes it writes empty string and flushes the buffer, in the end yo get the writer pointing to empty file

If the id column has no default value, but has NOT NULL constraint, then you have to provide a value yourself

INSERT INTO dbo.role (id, name, created) VALUES ('something', 'Content Coordinator', GETDATE()), ('Content Viewer', GETDATE())

you must use

 < SomeObject xml:space="preserve" > once upon a time ...
      this line will be below the first one < /SomeObject>

Or if you prefer :

 <SomeObject xml:space="preserve" />  once upon a time... &#10; this line below < / SomeObject>

watch out : if you both use &10 AND you go to the next line in your text, you'll have TWO empty lines.

clientX/Y refers to relative screen coordinates, for instance if your web-page is long enough then clientX/Y gives clicked point's coordinates location in terms of its actual pixel position while ScreenX/Y gives the ordinates in reference to start of page.

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

I agree with the other answers that using two containers is preferable, but if you have your heart set on bunding multiple services in a single container you can use something like supervisord.

in Hipache for instance, the included Dockerfile runs supervisord, and the file supervisord.conf specifies for both hipache and redis-server to be run.

I found this on Microsoft Dev Center. It works correctly and ignores double-clicking in wrong places. As you see, the point is that an item gets selected before double-click event is triggered.

private void listView1_DoubleClick(object sender, EventArgs e)
{
    // user clicked an item of listview control
    if (listView1.SelectedItems.Count == 1)
    {
        //do what you need to do here            
    }
}

To use information_schema and not collide with other sessions:

select * 
from tempdb.INFORMATION_SCHEMA.COLUMNS
where table_name =
    object_name(
        object_id('tempdb..#test'),
        (select database_id from sys.databases where name = 'tempdb'))

Using gnu find, I think this is what you want. It finds all real files and not directories (-type f), and for each one prints the filename (%p), a tab (\t), the size in kilobytes (%k), the suffix " KB", and then a newline (\n).

find . -type f -printf '%p\t%k KB\n'

If the printf command doesn't format things the way you want, you can use exec, followed by the command you want to execute on each file. Use {} for the filename, and terminate the command with a semicolon (;). On most shells, all three of those characters should be escaped with a backslash.

Here's a simple solution that finds and prints them out using "ls -lh", which will show you the size in human-readable form (k for kilobytes, M for megabytes):

find . -type f -exec ls -lh \{\} \;

As yet another alternative, "wc -c" will print the number of characters (bytes) in the file:

find . -type f -exec wc -c \{\} \;

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)

sub myhandler(eventsource)
  process(eventsource.value)
end sub

for each cell
  cell.setEventHandler(myHandler)

But i dont know the syntax for achieving this in VB/VBA, or if is even possible.

I ran into same issue when running:

$ /Users/<username>/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28" "build-tools;28.0.3"_

I solved it as

$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home    

$ ls /Library/Java/JavaVirtualMachines/

jdk-11.0.1.jdk      
jdk1.8.0_202.jdk

Change Java to use 1.8

$ export JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home'

Then the same command runs fine

$ /Users/<username>/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28" "build-tools;28.0.3"

Try to use CorFlagsReader from this project at CodePlex. It has no references to other assemblies and it can be used as is.

You should never apply bindings more than once to a view. In 2.2, the behaviour was undefined, but still unsupported. In 2.3, it now correctly shows an error. When using knockout, the goal is to apply bindings once to your view(s) on the page, then use changes to observables on your viewmodel to change the appearance and behaviour of your view(s) on your page.

In order to run the bootstrap date time picker you need to include Moment.js as well. Here is the working code sample in your case.

Just catch your exception and do proper exception handling:

if (cost !=null && !"".equals(cost) ){
        try {
           Integer intCost = Integer.parseInt(cost);
           List<Book> books = bookService . findBooksCheaperThan(intCost);  
        } catch (NumberFormatException e) {
           System.out.println("This is not a number");
           System.out.println(e.getMessage());
        }
    }

Your struct can have methods and properties... why not try

public struct MyStruct { 
    public string s;
    public int length { return s.Length; }
}

Correction @Guffa's answer shows that it is possible... more info here: http://www.codeproject.com/KB/cs/Csharp_implicit_operator.aspx

According to VBA help on SET statement it sets a reference to an object.so if you change a property the actual object will also changes.

Dim newObj as Object
Set var1=Object1(same type as Object)
Set var2=Object1(same type as Object)
Set var3=Object1(same type as Object)
Set var4=Object1(same type as Object)
Var1.property1=NewPropertyValue

the other Vars properties also changes,so:

Var1.property1=Var2.property1=Var3.property1=Var4.property1=Object1.Property1=NewpropertyValue`

actualy all vars are the same!

To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.

Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.

According to Apple's Data Formatting Guide

Creating a date formatter is not a cheap operation. If you are likely to use a formatter frequently, it is typically more efficient to cache a single instance than to create and dispose of multiple instances. One approach is to use a static variable

And while I agree with @Leon that this should be failable initializer, when you enter seed data, we could have one that isn't failable (just like there is UIImage(imageLiteralResourceName:)).

So here's my approach:

extension DateFormatter {
  static let yyyyMMdd: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd"
    formatter.calendar = Calendar(identifier: .iso8601)
    formatter.timeZone = TimeZone(secondsFromGMT: 0)
    formatter.locale = Locale(identifier: "en_US_POSIX")
    return formatter
  }()
}

extension Date {
    init?(yyyyMMdd: String) {
        guard let date = DateFormatter.yyyyMMdd.date(from: yyyyMMdd) else { return nil }
        self.init(timeInterval: 0, since: date)
    }

    init(dateLiteralString yyyyMMdd: String) {
        let date = DateFormatter.yyyyMMdd.date(from: yyyyMMdd)!
        self.init(timeInterval: 0, since: date)
    }
}

And now enjoy simply calling:

// For seed data
Date(dateLiteralString: "2020-03-30")

// When parsing data
guard let date = Date(yyyyMMdd: "2020-03-30") else { return nil }

math.fabs() always returns float, while abs() may return integer.

You are asking a few different questions...

• How can I create websites with Java?

The simplest way to start making websites with Java is to use JSP. JSP stands for Java Server Pages, and it allows you to embed HTML in Java code files for dynamic page creation. In order to compile and serve JSPs, you will need a Servlet Container, which is basically a web server that runs Java classes. The most popular basic Servlet Container is called Tomcat, and it's provided free by The Apache Software Foundation. Follow the tutorial that cletus provided here.

Once you have Tomcat up and running, and have a basic understanding of how to deploy JSPs, you'll probably want to start creating your own JSPs. I always like IBM developerWorks tutorials. They have a JSP tutorial here that looks alright (though a bit dated).

You'll find out that there is a lot more to Java web development than JSPs, but these tutorials will get you headed in the right direction.

• PHP vs. Java

This is a pretty subjective question. PHP and Java are just tools, and in the hands of a bad programmer, any tool is useless. PHP and Java both have their strengths and weaknesses, and the discussion of them is probably outside of the scope of this post. I'd say that if you already know Java, stick with Java.

• File I/O vs. MySQL

MySQL is better suited for web applications, as it is designed to handle many concurrent users. You should know though that Java can use MySQL just as easily as PHP can, through JDBC, Java's database connectivity framework.

IEnumerable<Book> _Book_IE;
List<Book> _Book_List;

If it's the generic variant:

_Book_IE = _Book_List;

If you want to convert to the non-generic one:

IEnumerable ie = (IEnumerable)_Book_List;

Without watches or observer callbacks (http://jsfiddle.net/zymotik/853wvv7s/):

JavaScript:

angular.module("Demo", [])
    .factory("DemoService", function($timeout) {

        function DemoService() {
            var self = this;
            self.name = "Demo Service";

            self.count = 0;

            self.counter = function(){
                self.count++;
                $timeout(self.counter, 1000);
            }

            self.addOneHundred = function(){
                self.count+=100;
            }

            self.counter();
        }

        return new DemoService();

    })
    .controller("DemoController", function($scope, DemoService) {

        $scope.service = DemoService;

        $scope.minusOneHundred = function() {
            DemoService.count -= 100;
        }

    });

HTML

<div ng-app="Demo" ng-controller="DemoController">
    <div>
        <h4>{{service.name}}</h4>
        <p>Count: {{service.count}}</p>
    </div>
</div>

This JavaScript works as we are passing an object back from the service rather than a value. When a JavaScript object is returned from a service, Angular adds watches to all of its properties.

Also note that I am using 'var self = this' as I need to keep a reference to the original object when the $timeout executes, otherwise 'this' will refer to the window object.

Below is the link which guide in parsing JSON string in android.

http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE

Also according to your json string code snippet must be something like this:-

JSONObject mainObject = new JSONObject(yourstring);

JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");  
JSONString url = universityObject.getString("url");

Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)

Same for other object.

2017 Update I guess. textarea worked fine for me using Spring, Bootstrap and a bunch of other things. Got the SOAP payload stored in a DB, read by Spring and push via Spring-MVC. xmp didn't work at all.

You say "Java" but "not Java EE". Do you mean you are using JSP and/or servlets but not a full Java EE stack? If that's the case, then you should still have request.getParameter() available to you.

If you mean you are writing Java but you are not writing JSPs nor servlets, or that you're just using Java as your reference point but you're on some other platform that doesn't have built-in parameter parsing ... Wow, that just sounds like an unlikely question, but if so, the principle would be:

xparm=0
word=""
loop
  get next char
  if no char
    exit loop
  if char=='='
    param_name[xparm]=word
    word=""
  else if char=='&'
    param_value[xparm]=word
    word=""
    xparm=xparm+1
  else if char=='%'
    read next two chars
    word=word+interpret the chars as hex digits to make a byte
  else
    word=word+char

(I could write Java code but that would be pointless, because if you have Java available, you can just use request.getParameters.)

It works like this:

h4 {
    display:inline;
}
h4:after {
    content:"\a";
    white-space: pre;
}

input fields can be styled as you wish. So instead of zoom, you could have

input[type="checkbox"]{
  width: 30px; /*Desired width*/
  height: 30px; /*Desired height*/
}

EDIT:

You would have to add extra rules like this:

input[type="checkbox"]{
  width: 30px; /*Desired width*/
  height: 30px; /*Desired height*/
  cursor: pointer;
  -webkit-appearance: none;
  appearance: none;
}

long __builtin_expect(long EXP, long C);

This construct tells the compiler that the expression EXP most likely will have the value C. The return value is EXP. __builtin_expect is meant to be used in an conditional expression. In almost all cases will it be used in the context of boolean expressions in which case it is much more convenient to define two helper macros:

#define unlikely(expr) __builtin_expect(!!(expr), 0)
#define likely(expr) __builtin_expect(!!(expr), 1)

These macros can then be used as in

if (likely(a > 1))

UIImage contains a CGImage as its main content member as well as scaling and orientation factors. Since CGImage and its various functions are derived from OSX, it expects a coordinate system that is upside down compared to the iPhone. When you create a UIImage, it defaults to an upside-down orientation to compensate (you can change this!). Use the .CGImage property to access the very powerful CGImage functions, but drawing onto the iPhone screen etc. is best done with the UIImage methods.

Another reason for the error might be is that Xcode is running a script during the run phase.

If this is the case, you have 2 options:

1. Delete the script (makes sense if the script is NOT important)

2. Modify/update the scripts location path (Xcode might not be able to locate the script)

In my case, the script was important, so I modified/updated its location.

Originally, the script location path was written like this:

$SRCROOT/scripts/clean-assets.sh

Because the scripts path contained spaces (I moved the project to a new directory), I changed the path to this:

"$SRCROOT"/scripts/clean-assets.sh

By adding quotes to SRCROOT, changing it to "$SRCROOT", the error will go away.

This is trivial when you use SUMPRODUCT. Por ejemplo:

=SUMPRODUCT((worksheet2!A:A=A3)*1)

You could put the above formula in cell B3, where A3 is the name you want to find in worksheet2.

I know this is an old question, but none of the answers worked for me, because I wanted to reliably (always be able to) set the cell into edit mode when possibly executing other events like Toolbar Button clicks, menu selections, etc. that may affect the default focus after those events return. I ended up needing a timer and invoke. The following code is in a new component derived from DataGridView. This code allows me to simply make a call to myXDataGridView.CurrentRow_SelectCellFocus(myDataPropertyName); anytime I want to arbitrarily set a databound cell to edit mode (assuming the cell is Not in ReadOnly mode).

// If the DGV does not have Focus prior to a toolbar button Click, 
// then the toolbar button will have focus after its Click event handler returns.
// To reliably set focus to the DGV, we need to time it to happen After event handler procedure returns.

private string m_SelectCellFocus_DataPropertyName = "";
private System.Timers.Timer timer_CellFocus = null;

public void CurrentRow_SelectCellFocus(string sDataPropertyName)
{
  // This procedure is called by a Toolbar Button's Click Event to select and set focus to a Cell in the DGV's Current Row.
  m_SelectCellFocus_DataPropertyName = sDataPropertyName;
  timer_CellFocus = new System.Timers.Timer(10);
  timer_CellFocus.Elapsed += TimerElapsed_CurrentRowSelectCellFocus;
  timer_CellFocus.Start();
}


void TimerElapsed_CurrentRowSelectCellFocus(object sender, System.Timers.ElapsedEventArgs e)
{
  timer_CellFocus.Stop();
  timer_CellFocus.Elapsed -= TimerElapsed_CurrentRowSelectCellFocus;
  timer_CellFocus.Dispose();
  // We have to Invoke the method to avoid raising a threading error
  this.Invoke((MethodInvoker)delegate
  {
    Select_Cell(m_SelectCellFocus_DataPropertyName);
  });
}


private void Select_Cell(string sDataPropertyName)
{
  /// When the Edit Mode is Enabled, set the initial cell to the Description
  foreach (DataGridViewCell dgvc in this.SelectedCells) 
  {
    // Clear previously selected cells
    dgvc.Selected = false; 
  }
  foreach (DataGridViewCell dgvc in this.CurrentRow.Cells)
  {
    // Select the Cell by its DataPropertyName
    if (dgvc.OwningColumn.DataPropertyName == sDataPropertyName)
    {
      this.CurrentCell = dgvc;
      dgvc.Selected = true;
      this.Focus();
      return;
    }
  }
}

Updated code

$('a','div.res').click(function(){
  var currentAnchor = $(this);
  alert(currentAnchor.text());
  alert(currentAnchor.attr('href'));
});

I was looking for something similar myself, preferably without using a library or sorting the entire list. My solution ended up similar to the question itself, just simplified a bit.

var firstBorn = People.FirstOrDefault(p => p.DateOfBirth == People.Min(p2 => p2.DateOfBirth));

in typeScript of angular 6, this code is working for me.

var formData = new FormData();
formData.append('name', 'value1');
formData.append('name', 'value2');
console.log(formData.get('name')); // this is return first element value.

or for all values:

console.log(formData.getAll('name')); // return all values

memset (from <string.h>) is probably the fastest standard way, since it's usually a routine written directly in assembly and optimized by hand.

memset(myarray, 0, sizeof(myarray)); // for automatically-allocated arrays
memset(myarray, 0, N*sizeof(*myarray)); // for heap-allocated arrays, where N is the number of elements

By the way, in C++ the idiomatic way would be to use std::fill (from <algorithm>):

std::fill(myarray, myarray+N, 0);

which may be optimized automatically into a memset; I'm quite sure that it will work as fast as memset for ints, while it may perform slightly worse for smaller types if the optimizer isn't smart enough. Still, when in doubt, profile.

For a pure numpy implementation of Cartesian product of 1D arrays (or flat python lists), just use meshgrid(), roll the axes with transpose(), and reshape to the desired ouput:

 def cartprod(*arrays):
     N = len(arrays)
     return transpose(meshgrid(*arrays, indexing='ij'), 
                      roll(arange(N + 1), -1)).reshape(-1, N)

Note this has the convention of last axis changing fastest ("C style" or "row-major").

If you want to change the first axis fastest ("FORTRAN style" or "column-major"), just change the order parameter of reshape() like this: reshape((-1, N), order='F')

All answers are correct, but you need to convert a long big fat number into a timer first:

    public String toTimer(long milliseconds){
    String finalTimerString = "";
    String secondsString;
    // Convert total duration into time
    int hours = (int)( milliseconds / (1000*60*60));
    int minutes = (int)(milliseconds % (1000*60*60)) / (1000*60);
    int seconds = (int) ((milliseconds % (1000*60*60)) % (1000*60) / 1000);
    // Add hours if there
    if(hours > 0){
        finalTimerString = hours + ":";
    }
    // Prepending 0 to seconds if it is one digit
    if(seconds < 10){
        secondsString = "0" + seconds;
    }else{
        secondsString = "" + seconds;}
    finalTimerString = finalTimerString + minutes + ":" + secondsString;
    // return timer string
    return finalTimerString;
}

And this is how you use it:

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
textView.setText(String.format("%s", toTimer(progress)));        
}

It registers the driver; something of the form:

public class SomeDriver implements Driver {
  static {
    try {
      DriverManager.registerDriver(new SomeDriver());
    } catch (SQLException e) {
      // TODO Auto-generated catch block
    }
  }

  //etc: implemented methods
}

Update in 2020 in Php7:

there is a better way to do this using the Null coalescing operator by just doing the following:

$data[$parts[0]] = $parts[1] ?? null;

I had the same problem. Initially I had setup Eclipse CDT with Cygwing & was working smoothly. One day there happened a problem due to which I had to reset windows. After that when I opened Eclipse I started facing the issue described above. This is how I solved it.

First I searched that in the error the PATH variable value is same as the PATH variable of windows ( just by manual comparison of both two values ). I found that to be same. Now I realized that it is a PATH problem.

Then started looking for Cygwin whether it is there or not? It was there. I located & found that it exists in

C:\cygwin64\bin>

Then I simply went ahead & updated the PATH variable to include this path & restarted eclipse.

The code compiles & debugging (GDB ) is working nicely.

Hope this helps.

Set the original background-color in you CSS file:

.forum{
    background-color:#f0f;
}?

You don't have to capture the original color in jQuery. Remember that jQuery will alter the style INLINE, so by setting the background-color to null you will get the same result.

$(function() {
    $(".forum").hover(
    function() {
        $(this).css('background-color', '#ff0')
    }, function() {
        $(this).css('background-color', '')
    });
});?

It works with C#.

In Bash, I would use the following one-liner:

[[ "${str}" == \"*\" || "${str}" == \'*\' ]] && str="${str:1:-1}"

This will remove surrounding quotes (both single and double) while keeping quoting characters inside the string intact. Also, it won't do anything if there's only a single leading quote or only a single trailing quote, which is usually what you want in my experience.

Wrapped in a function:

#!/usr/bin/env bash

# Strip surrounding quotes from string [$1: variable name]
function strip_quotes() {
    local -n var="$1"
    [[ "${var}" == \"*\" || "${var}" == \'*\' ]] && var="${var:1:-1}"
}

str="$*"
echo "Before: ${str}"
strip_quotes str
echo "After:  ${str}"

You should use "readonly" instead like:

$("input[type='text']").attr("readonly", "true");

UPDATE some_table 
   SET this_column=x, that_column=y 
   WHERE something LIKE 'them'

In VB.NET:

Dim webClient As New System.Net.WebClient
Dim result As String = webClient.DownloadString("http://api.hostip.info/?ip=68.180.206.184")

In C#:

System.Net.WebClient webClient = new System.Net.WebClient();
string result = webClient.DownloadString("http://api.hostip.info/?ip=68.180.206.184");

Do whatever you want to do after the file loads successfully.just after the completion of your file processing set the value of file control to blank string.so the .change() will always be called even the file name changes or not. like for example you can do this thing and worked for me like charm

  $('#myFile').change(function () {
    LoadFile("myFile");//function to do processing of file.
    $('#myFile').val('');// set the value to empty of myfile control.
    });

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

Html.ActionLink generates an <a href=".."></a> tag automatically.

Url.Action generates only an url.

For example:

@Html.ActionLink("link text", "actionName", "controllerName", new { id = "<id>" }, null)

generates:

<a href="/controllerName/actionName/<id>">link text</a>

and

@Url.Action("actionName", "controllerName", new { id = "<id>" }) 

generates:

/controllerName/actionName/<id>

Best plus point which I like is using Url.Action(...)

You are creating anchor tag by your own where you can set your own linked text easily even with some other html tag.

<a href="@Url.Action("actionName", "controllerName", new { id = "<id>" })">

   <img src="<ImageUrl>" style"width:<somewidth>;height:<someheight> />

   @Html.DisplayFor(model => model.<SomeModelField>)
</a>

Given an instance of the struct, you set the values.

    student thisStudent;
    Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
    thisStudent.s_id = int.Parse(Console.ReadLine());
    thisStudent.s_name = Console.ReadLine();
    thisStudent.c_name = Console.ReadLine();
    thisStudent.s_dob = Console.ReadLine();

Note this code is incredibly fragile, since we aren't checking the input from the user at all. And you aren't clear to the user that you expect each data point to be entered on a separate line.

The file module doesn't copy files on the remote system. The src parameter is only used by the file module when creating a symlink to a file.

If you want to move/rename a file entirely on a remote system then your best bet is to use the command module to just invoke the appropriate command:

- name: Move foo to bar
  command: mv /path/to/foo /path/to/bar

If you want to get fancy then you could first use the stat module to check that foo actually exists:

- name: stat foo
  stat: path=/path/to/foo
  register: foo_stat

- name: Move foo to bar
  command: mv /path/to/foo /path/to/bar
  when: foo_stat.stat.exists

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

You can use default values for the parameters of stored procedures:

CREATE PROCEDURE MyTestProcedure ( @MyParam1 INT,
@MyParam2 VARCHAR(20) = ‘ABC’,
@MyParam3 INT = NULL)
AS
BEGIN
    -- Procedure body here

END

If @MyParam2 is not supplied, it will have the 'ABC' value...

If you do not use any placeholders (as the "exactly" seems to imply), how about string comparison instead?

If you do use placeholders, ^ and $ match the beginning and the end of a string, respectively.

In Lollipop (21), you can use Intent.EXTRA_REPLACEMENT_EXTRAS to override the intent for Facebook specifically (and specify a link only)

https://developer.android.com/reference/android/content/Intent.html#EXTRA_REPLACEMENT_EXTRAS

private void doShareLink(String text, String link) {
  Intent shareIntent = new Intent(Intent.ACTION_SEND);
  shareIntent.setType("text/plain");
  Intent chooserIntent = Intent.createChooser(shareIntent, getString(R.string.share_via));

  // for 21+, we can use EXTRA_REPLACEMENT_EXTRAS to support the specific case of Facebook
  // (only supports a link)
  // >=21: facebook=link, other=text+link
  // <=20: all=link
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    shareIntent.putExtra(Intent.EXTRA_TEXT, text + " " + link);
    Bundle facebookBundle = new Bundle();
    facebookBundle.putString(Intent.EXTRA_TEXT, link);
    Bundle replacement = new Bundle();
    replacement.putBundle("com.facebook.katana", facebookBundle);
    chooserIntent.putExtra(Intent.EXTRA_REPLACEMENT_EXTRAS, replacement);
  } else {
    shareIntent.putExtra(Intent.EXTRA_TEXT, link);
  }

  chooserIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  startActivity(chooserIntent);
}

What about:

This is called type conversion :

var i64 int64
i64 = int64(i)

When I was facing this issue I used to install OpenCV in pycharm installed package panel where we can find under the settings tab. Search "OpenCV-python" and install it in the installed package panel of right interpreter.

setSelection(int index) method in Edittext should allow you to do this.

Just restarting Eclipse fixed the issue in my project

Multiple column search with dataframe:

Using Bootstrap 3.3.5 and .container-fluid, this is how I get full width with no gutters or horizontal scrolling on mobile. Note that .container-fluid was re-introduced in 3.1.

Full width on mobile/tablet, 1/4 screen on desktop

<div class="container-fluid"> <!-- Adds 15px left/right padding --> 
  <div class="row"> <!-- Adds -15px left/right margins -->
    <div class="col-md-4 col-md-offset-4" style="padding-left: 0, padding-right: 0"> <!-- col classes adds 15px padding, so remove the same amount -->
      <!-- Full-width for mobile -->
      <!-- 1/4 screen width for desktop -->
    </div>
  </div>
</div>

Full width on all resolutions (mobile, table, desktop)

<div class="container-fluid"> <!-- Adds 15px left/right padding -->
  <div class="row"> <!-- Adds -15px left/right margins -->
    <div>
      <!-- Full-width content -->
    </div>
  </div>
</div>

Important! Difference between Oracle and Mysql: Let's say that t1 t2 don't have duplicate rows between them but they have duplicate rows individual. Example: t1 has sales from 2017 and t2 from 2018

SELECT T1.YEAR, T1.PRODUCT FROM T1

UNION ALL

SELECT T2.YEAR, T2.PRODUCT FROM T2

In ORACLE UNION ALL fetches all rows from both tables. The same will occur in MySQL.

However:

SELECT T1.YEAR, T1.PRODUCT FROM T1

UNION

SELECT T2.YEAR, T2.PRODUCT FROM T2

In ORACLE, UNION fetches all rows from both tables because there are no duplicate values between t1 and t2. On the other hand in MySQL the resultset will have fewer rows because there will be duplicate rows within table t1 and also within table t2!

1. Start a graphical vim session.
2. Do :e $MYGVIMRC Enter
3. Use the graphical font selection dialog to select a font.
4. Type :set guifont= Tab Enter.
5. Type G o to start a new line at the end of the file.
6. Type Ctrl+R followed by :.

The command in step 6 will insert the contents of the : special register which contains the last ex-mode command used. Here that will be the command from step 4, which has the properly formatted font name thanks to the tab completion of the value previously set using the GUI dialog.

$host is a variable of the Core module.

$host

This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.

This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.

$http_host is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER (ref).

$http_HEADER

The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;

Summarizing:

• $http_host equals always the HTTP_HOST request header.
• $host equals $http_host, lowercase and without the port number (if present), except when HTTP_HOST is absent or is an empty value. In that case, $host equals the value of the server_name directive of the server which processed the request.

Use max():

 
Using itemgetter():

In [53]: lis=[(101, 153), (255, 827), (361, 961)]

In [81]: from operator import itemgetter

In [82]: max(lis,key=itemgetter(1))[0]    #faster solution
Out[82]: 361

using lambda:

In [54]: max(lis,key=lambda item:item[1])
Out[54]: (361, 961)

In [55]: max(lis,key=lambda item:item[1])[0]
Out[55]: 361

timeit comparison:

In [30]: %timeit max(lis,key=itemgetter(1))
1000 loops, best of 3: 232 us per loop

In [31]: %timeit max(lis,key=lambda item:item[1])
1000 loops, best of 3: 556 us per loop

I ran into problems with just an FittedBox so I wrapped my Image in an LayoutBuilder:

LayoutBuilder( 
   builder: (_, constraints) => Image(
      fit: BoxFit.fill,
      width: constraints.maxWidth,
      image: AssetImage(assets.example),
   ),
)

This worked like a charm and I suggest you give it a try.
Of course you can use height instead of width, this is just what I used.

First of all I wanted to thank jimbo and (his post / twitter-api-php simple library).

If you are going to use the GET search/tweets API with "twitter-api-php" PHP library (TwitterAPIExchange.php):

First, you have to just comment "Perform a POST request and echo the response " code area.

Just use "Perform a GET request and echo the response" code and echo the response and change these two lines:

$url = 'https://api.twitter.com/1.1/followers/ids.json';
$getfield = '?screen_name=J7mbo';

to

$url = 'https://api.twitter.com/1.1/search/tweets.json';
$getfield = '?q=J7mbo';

(Change screen_name to q, that's it :)

Using toLocaleString ref at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString

function formatComma(value, sep = 0) {_x000D_
      return Number(value).toLocaleString("ja-JP", { style: "currency", currency: "JPY", minimumFractionDigits: sep });_x000D_
    }_x000D_
console.log(formatComma(123456789, 2)); // ?123,456,789.00_x000D_
console.log(formatComma(123456789, 0)); // ?123,456,789_x000D_
console.log(formatComma(1234, 0)); // ?1,234

Yes, you can use mysqldump with the --no-data option:

mysqldump -u user -h localhost --no-data -p database > database.sql

Vavr (formerly called Javaslang) (http://www.vavr.io) provides tuples (til size of 8) as well. Here is the javadoc: https://static.javadoc.io/io.vavr/vavr/0.9.0/io/vavr/Tuple.html.

This is a simple example:

Tuple2<Integer, String> entry = Tuple.of(1, "A");

Integer key = entry._1;
String value = entry._2;

Why JDK itself did not come with a simple kind of tuples til now is a mystery to me. Writing wrapper classes seems to be an every day business.

I had a different problem from what all of the answers so far mentioned!

I should start off by saying that I had it in Visual Studio, and not SQL Server Express but the solution should be exactly the same.

Well, god, it's actually really simple and maybe a bit foolish. When I tried to create a database and Visual Studio suggested the name of the SQL Server it gave me my Windows username and since it's actually the name of the server I went for it.

In reality it actually was my Windows username + \SQLEXPRESS. If you didn't change any settings this is probably yours too. If it works, stop reading; this is my answer. If it doesn't work maybe the name is different.

If, like me, you only had this problem in Visual Studio to check what is yours follow these steps:

1. Open SQL Server Management Studio^icon.
2. If you don't see your server (docked to the left by default) press F8 or go to View -> Object Explorer.
3. Right click on the name of the server and choose Properties (The last item)
4. At the bottom left you can see your server's actual name under "Server" (not Connection, but above it).

This is the name of the server and this is what you should attempt to connect to! not what Visual Studio suggests!

You don't need to use character codes; just use UTF-8 and put them in literally; like so:

??

If you absolutely must use the entites, they are ▲ and ▼, respectively.

As @hitec said, you have to be sure that you have the right permissions, if you do, you can use this line to ensure the existence of the directory:

Directory.CreateDirectory(Path.GetDirectoryName(filePath))

Perhaps the best choice to avoid linking containers issues are the docker networking features

But to make this work, docker creates entries in the /etc/hosts for each container from assigned names to each container.

with docker-compose --x-networking -up is something like [docker_compose_folder]-[service]-[incremental_number]

To not depend on unexpected changes in these names you should use the parameter

container_name

in your docker-compose.yml as follows:

php:
      container_name: waapi_php_1
      build: config/docker/php
      ports:
        - "42022:22"
      volumes:
        - .:/var/www/html
      env_file: config/docker/php/.env.development

Making sure that it is the same name assigned in your configuration file for this service. I'm pretty sure there are better ways to do this, but it is a good approach to start.

Extract the information from the database for the checkbox fields. Next change the above example line to: (this code assumes that you've retrieved the information for the user into an associative array called dbvalue and the DB field names match those on the HTML form)

<input type="checkbox" name="tag_1" id="tag_1" value="yes" <?php echo ($dbvalue['tag_1']==1 ? 'checked' : '');?>>

If you're looking for the code to do everything for you, you've come to the wrong place.

static function definitions will mark this symbol as internal. So it will not be visible for linking from outside, but only to functions in the same compilation unit, usually the same file.

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

The foreach underhood is creating the iterator, calling hasNext() and calling next() to get the value; The issue with the performance comes only if you are using something that implements the RandomomAccess.

for (Iterator<CustomObj> iter = customList.iterator(); iter.hasNext()){
   CustomObj custObj = iter.next();
   ....
}

Performance issues with the iterator-based loop is because it is:

1. allocating an object even if the list is empty (Iterator<CustomObj> iter = customList.iterator(););
2. iter.hasNext() during every iteration of the loop there is an invokeInterface virtual call (go through all the classes, then do method table lookup before the jump).
3. the implementation of the iterator has to do at least 2 fields lookup in order to make hasNext() call figure the value: #1 get current count and #2 get total count
4. inside the body loop, there is another invokeInterface virtual call iter.next(so: go through all the classes and do method table lookup before the jump) and as well has to do fields lookup: #1 get the index and #2 get the reference to the array to do the offset into it (in every iteration).

A potential optimiziation is to switch to an index iteration with the cached size lookup:

for(int x = 0, size = customList.size(); x < size; x++){
  CustomObj custObj = customList.get(x);
  ...
}

Here we have:

1. one invokeInterface virtual method call customList.size() on the initial creation of the for loop to get the size
2. the get method call customList.get(x) during the body for loop, which is a field lookup to the array and then can do the offset into the array

We reduced a ton of method calls, field lookups. This you don't want to do with LinkedList or with something that is not a RandomAccess collection obj, otherwise the customList.get(x) is gonna turn into something that has to traverse the LinkedList on every iteration.

This is perfect when you know that is any RandomAccess based list collection.

This is not my prefered way to do this, cause of massive CPU consumption.

If that is actually your working code, then just keep it like that. Checking a boolean once a second causes NO measurable CPU load. None whatsoever.

The real problem is that the thread that checks the value may not see a change that has happened for an arbitrarily long time due to caching. To ensure that the value is always synchronized between threads, you need to put the volatile keyword in the variable definition, i.e.

private volatile boolean value;

Note that putting the access in a synchronized block, such as when using the notification-based solution described in other answers, will have the same effect.

I'm not an Oracle user (well, lately anyhow), BUT...

In most databases (and in precise language), a date doesn't include a time. Having a date doesn't imply that you are denoting a specific second on that date. Generally if you want a time as well as a date, that's called a timestamp.

You can use document.write, however it's not a good practice, it may clear the entire page depends on when it's being executed.

You should use Element.innerHtml like this:

<div>foo</div>
<span id="insertHere"></span>
<div>bar</div>

<script>
document.getElementById('insertHere').innerHTML = '<div>Print this after the script tag</div>';
</script>

Here is a batch file that generates all 10.x.x.x addresses

@echo off

SET /A X=0
SET /A Y=0
SET /A Z=0

:loop
SET /A X+=1
echo 10.%X%.%Y%.%Z%
IF "%X%" == "256" (
 GOTO end
 ) ELSE (
 GOTO loop2
 GOTO loop
 )


:loop2
SET /A Y+=1
echo 10.%X%.%Y%.%Z%
IF "%Y%" == "256" (
  SET /A Y=0
  GOTO loop
  ) ELSE (
   GOTO loop3
   GOTO loop2
 )


:loop3

SET /A Z+=1
echo 10.%X%.%Y%.%Z%
IF "%Z%" == "255" (

When you define concatenation you need to use an ALIAS for the new column if you want to order on it combined with DISTINCT Some Ex with sql 2008

--this works 

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName 
    from SalesLT.Customer c 
    order by FullName

--this works too

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) 
    from SalesLT.Customer c 
    order by 1

-- this doesn't 

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName 
    from SalesLT.Customer c 
    order by c.FirstName, c.LastName

-- the problem the DISTINCT needs an order on the new concatenated column, here I order on the singular column
-- this works

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) 
        as FullName, CustomerID 
        from SalesLT.Customer c 

order by 1, CustomerID

-- this doesn't

    SELECT DISTINCT (c.FirstName + ' ' + c.LastName) as FullName 
     from SalesLT.Customer c 
      order by 1, CustomerID

It appears this issue is fixed in npm v5.4.2

https://github.com/npm/npm/issues/17979

(Scroll down to the last comment in the thread)

Update

Actually fixed in 5.6.0. There was a cross platform bug in 5.4.2 that was causing the issue to still occur.

https://github.com/npm/npm/issues/18712

Update 2

See my answer here: https://stackoverflow.com/a/53680257/1611058

npm ci is the command you should be using when installing existing projects now.

An application does not need to have any registry entry. In fact, many applications do not need to be installed at all. U3 USB sticks are a good example; the programs on them just run from the file system.

As noted, most good applications can be found via their uninstall registry key though. This is actually a pair of keys, per-user and per-machine (HKCU/HKLM - Piskvor mentioned only the HKLM one). It does not (always) give you the install directory, though.

If it's in HKCU, then you have to realise that HKEY_CURRENT_USER really means "Current User". Other users have their own HKCU entries, and their own installed software. You can't find that. Reading every HKEY_USERS hive is a disaster on corporate networks with roaming profiles. You really don't want to fetch 1000 accounts from your remote [US|China|Europe] office.

Even if an application is installed, and you know where, it may not have the same "version" notion you have. The best source is the "version" resource in the executables. That's indeed a plural, so you have to find all of them, extract version resources from all and in case of a conflict decid on something reasonable.

So - good luck. There are dozes of ways to fail.

From the docs

In the Java programming language, every application must contain a main method whose signature is:

public static void main(String[] args)

The modifiers public and static can be written in either order (public static or static public), but the convention is to use public static as shown above. You can name the argument anything you want, but most programmers choose "args" or "argv".

As you say:

error: missing method body, or declare abstract public static void main(String[] args); ^ this is what i got after i added it after the class name

You probably haven't declared main with a body (as ';" would suggest in your error).

You need to have main method with a body, which means you need to add { and }:

public static void main(String[] args) {


}

Add it inside your class definition.

Although sometimes error messages are not very clear, most of the time they contain enough information to point to the issue. Worst case, you can search internet for the error message. Also, documentation can be really helpful.

this is how i did it

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. (If the ‘-e’ flag is specified, then values from the environment override assignments in the makefile.

I think the only foolproof method you can have is creating a Contact Me page that is a form that submits to a script that sends to your email address. That way, your address is never exposed to the public at all. This may be undesirable for some reason, but I think it's a pretty good solution. It often irks me when I'm forced to copy/paste someone's email address from their site to my mail client and send them a message; I'd rather do it right through a form on their site. Also, this approach allows you to have anonymous comments sent to you, etc. Just be sure to protect your form using some kind of anti-bot scheme, such as a captcha. There are plenty of them discussed here on SO.

You can do it in two ways:

First:

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    const listItems = data.map((d) => <li key={d.name}>{d.name}</li>);

    return (
      <div>
      {listItems }
      </div>
    );
  }

Second: Directly write the map function in the return

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    return (
      <div>
      {data.map(function(d, idx){
         return (<li key={idx}>{d.name}</li>)
       })}
      </div>
    );
  }

-split outputs an array, and you can save it to a variable like this:

$a = -split 'Once  upon    a     time'
$a[0]

Once

Another cute thing, you can have arrays on both sides of an assignment statement:

$a,$b,$c = -split 'Once  upon    a'
$c

a

Recently I had the need to perform some encryption/decryption interoperability between javascript and python.

Specifically...

1) Using AES to encrypt in javascript and decrypt in python (Google App Engine) 2) Using RSA to encrypt in javascript and decrypt in python (Google App Engine) 3) Using pycrypto

I found lots and lots of different versions of RSA and AES floating around the web and they were all different in their approach but I did not find a good example of end to end javascript and python interoperability.

Eventually I managed to cobble together something that suited my needs after a lot of trial and error.

Anyhow I knocked up an example of a js/webapp talking to a google app engine hosted python server that uses AES and public key and private key RSA stuff.

I though I'd include it here by link in case it will be of some use to others who need to accomplish the same thing.

http://www.ipowow.com/files/aesrsademo.tar.gz

and see demo at rsa-aes-demo DOT appspot DOT com

edit: look at the browser console output and also view source to get some hints and useful messages as to what's going on in the demo

edit: updated very old and defunct link to source to now point to

You can do it a number of ways, depending on the type of quotes you use:

• echo "<a href='http://www.whatever.com/$param'>Click here</a>";
• echo "<a href='http://www.whatever.com/{$param}'>Click here</a>";
• echo '<a href="http://www.whatever.com/' . $param . '">Click here</a>';
• echo "<a href=\"http://www.whatever.com/$param\">Click here</a>";

Double quotes allow for variables in the middle of the string, where as single quotes are string literals and, as such, interpret everything as a string of characters -- nothing more -- not even \n will be expanded to mean the new line character, it will just be the characters \ and n in sequence.

You need to be careful about your use of whichever type of quoting you decide. You can't use double quotes inside a double quoted string (as in your example) as you'll be ending the string early, which isn't what you want. You can escape the inner double quotes, however, by adding a backslash.

On a separate note, you might need to be careful about XSS attacks when printing unsafe variables (populated by the user) out to the browser.

I had this error in my DNN application installed on Windows 2012 R2. It's using some 32 bit dll and only Oracle.DataAccess.dll x32 was working. My solution is:

1. Uninstall old Oracle Client \ ODAC.
2. Install Oracle 11 Client x32.
3. Install Oracle ODAC 12 x64.
4. Check IIS Application Pool (Classic version) has option "Enable 32-Bit Applications" = true.

You can use Google's Gson library to convert json to Hashmap. Try below code

String jsonString = "Your JSON string";
HashMap<String,String> map = new Gson().fromJson(jsonString, new TypeToken<HashMap<String, String>>(){}.getType());

I tried everything form everywhere. Nothing worked until I did this. Following the steps below.

RPC:AEC:0 error is known as CPU/RAM/Device/Identity failure.

Only possible way you can follow to get rid off this error is,

Go to settings → application → Play Store → Clear Data & Clear Cache.

Go to accounts → Google → Remove account.

Reboot device.

Again Settings → Account → Google → Log In.

This worked best for me:

import decimal
'%.2E' % decimal.Decimal('40800000000.00000000000000')
# 4.08E+10

Using Guava you can easily combine different type of criteria. For your specific solution you can use:

value = CharMatcher.inRange('0', '9')
        .or(CharMatcher.inRange('a', 'z')
        .or(CharMatcher.inRange('A', 'Z'))).retainFrom(value)

There is also other way to generate log file.

Before running ansible-playbook run the following commands to enable logging:

• Specify the location for the log file.

  export ANSIBLE_LOG_PATH=~/ansible.log

• Enable Debug

  export ANSIBLE_DEBUG=True

• To check that generated log file.

  less $ANSIBLE_LOG_PATH

Based on Aladin Q's solution, here is a helper function that I wrote, that will change the image in an imageview while running a little fade out / fade in animation:

public static void ImageViewAnimatedChange(Context c, final ImageView v, final Bitmap new_image) {
        final Animation anim_out = AnimationUtils.loadAnimation(c, android.R.anim.fade_out); 
        final Animation anim_in  = AnimationUtils.loadAnimation(c, android.R.anim.fade_in); 
        anim_out.setAnimationListener(new AnimationListener()
        {
            @Override public void onAnimationStart(Animation animation) {}
            @Override public void onAnimationRepeat(Animation animation) {}
            @Override public void onAnimationEnd(Animation animation)
            {
                v.setImageBitmap(new_image); 
                anim_in.setAnimationListener(new AnimationListener() {
                    @Override public void onAnimationStart(Animation animation) {}
                    @Override public void onAnimationRepeat(Animation animation) {}
                    @Override public void onAnimationEnd(Animation animation) {}
                });
                v.startAnimation(anim_in);
            }
        });
        v.startAnimation(anim_out);
    }

I found this to work best, if any image fails to load the first time, it is completely removed from the DOM. Executing console.clear() keeps the console window clean, since the 404 errors cannot be omitted with try/catch blocks.

$('img').one('error', function(err) {
    // console.log(JSON.stringify(err, null, 4))
    $(this).remove()
    console.clear()
})

I enabled Trust Server Certificate in the Connection Properties and it worked for me

Create a copy of executables of same service and paste it on the same path of the existing service and then uninstall.

All the solutions that check a multitude of conditions based on where the ranges are in relation to one another can be greatly simplified by just ensuring that a specific range starts earlier! You ensure that the first range starts earlier (or at the same time) by swapping the ranges if necessary up front.

Then, you can detect overlap if the other range start is less than or equal to the first range end (if ranges are inclusive, containing both the start and end times) or less than (if ranges are inclusive of start and exclusive of end).

Assuming inclusive at both ends, there's only four possibilities of which one is a non-overlap:

|----------------------|        range 1
|--->                           range 2 overlap
 |--->                          range 2 overlap
                       |--->    range 2 overlap
                        |--->   range 2 no overlap

The endpoint of the range 2 doesn't enter into it. So, in pseudo-code:

def doesOverlap (r1, r2):
    if r1.s > r2.s:
        swap r1, r2
    if r2.s > r1.e:
        return false
    return true

This could be simplified even more into:

def doesOverlap (r1, r2):
    if r1.s > r2.s:
        swap r1, r2
    return r2.s <= r1.e

If the ranges are inclusive at the start and exclusive at the end, you just have to replace > with >= in the second if statement (for the first code segment: in the second code segment, you'd use < rather than <=):

|----------------------|        range 1
|--->                           range 2 overlap
 |--->                          range 2 overlap
                       |--->    range 2 no overlap
                        |--->   range 2 no overlap

You greatly limit the number of checks you have to make because you remove half of the problem space early by ensuring range 1 never starts after range 2.

Setting the background to "@null" will make the button have no effect when clicked. This will be a better choice.

style="?android:attr/borderlessButtonStyle"

Later I found that using

android:background="?android:attr/selectableItemBackground"

is also a good solution. And you can inherit this attribute in your own style.

Or with a constructor & linq with Select:

public class TargetType {
  public string Prop1 {get;set;}
  public string Prop1 {get;set;}

  // Constructor
  public TargetType(OrigType origType) {
    Prop1 = origType.Prop1;
    Prop2 = origType.Prop2;
  }
}

var origList = new List<OrigType>();
var targetList = origList.Select(s=> new TargetType(s)).ToList();  

The Linq line is more soft! ;-)

From a little search, that I understand the file should be opened in universal newline mode, which you cannot directly do with a response content (I guess).

To finish the task, you can either save the downloaded content to a temporary file, or process it in memory.

Save as file:

import requests
import csv
import os

temp_file_name = 'temp_csv.csv'
url = 'http://url.to/file.csv'
download = requests.get(url)

with open(temp_file_name, 'w') as temp_file:
    temp_file.writelines(download.content)

with open(temp_file_name, 'rU') as temp_file:
    csv_reader = csv.reader(temp_file, dialect=csv.excel_tab)
    for line in csv_reader:
        print line

# delete the temp file after process
os.remove(temp_file_name)

In memory:

(To be updated)

Try this:

tr -d " \t" <filename

See the manpage for tr(1) for more details.

Integer foo[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 };

List<Integer> list = Arrays.asList(foo);
// or
Iterable<Integer> iterable = Arrays.asList(foo);

Though you need to use an Integer array (not an int array) for this to work.

For primitives, you can use guava:

Iterable<Integer> fooBar = Ints.asList(foo);

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>15.0</version>
    <type>jar</type>
</dependency>

For Java8: (from Jin Kwon's answer)

final int[] arr = {1, 2, 3};
final PrimitiveIterator.OfInt i1 = Arrays.stream(arr).iterator();
final PrimitiveIterator.OfInt i2 = IntStream.of(arr).iterator();
final Iterator<Integer> i3 = IntStream.of(arr).boxed().iterator();

What you want is org.mockito.Mockito.CALLS_REAL_METHODS according to the docs:

 * This implementation can be helpful when working with legacy code.
 * When this implementation is used, unstubbed methods will delegate to the real implementation.
 * This is a way to create a partial mock object that calls real methods by default.
 * <p>
 * As usual you are going to read <b>the partial mock warning</b>:
 * Object oriented programming is more less tackling complexity by dividing the complexity into separate, specific, SRPy objects.
 * How does partial mock fit into this paradigm? Well, it just doesn't... 
 * Partial mock usually means that the complexity has been moved to a different method on the same object.
 * In most cases, this is not the way you want to design your application.
 * <p>
 * However, there are rare cases when partial mocks come handy: 
 * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.)
 * However, I wouldn't use partial mocks for new, test-driven & well-designed code.
 * <p>
 * Example:
 * <pre class="code"><code class="java">
 * Foo mock = mock(Foo.class, CALLS_REAL_METHODS);
 *
 * // this calls the real implementation of Foo.getSomething()
 * value = mock.getSomething();
 *
 * when(mock.getSomething()).thenReturn(fakeValue);
 *
 * // now fakeValue is returned
 * value = mock.getSomething();
 * </code></pre>

Thus your code should look like:

import org.junit.Test;
import static org.mockito.Mockito.*;
import static org.junit.Assert.*;

public class StockTest {

    public class Stock {
        private final double price;
        private final int quantity;

        Stock(double price, int quantity) {
            this.price = price;
            this.quantity = quantity;
        }

        public double getPrice() {
            return price;
        }

        public int getQuantity() {
            return quantity;
        }

        public double getValue() {
            return getPrice() * getQuantity();
        }
    }

    @Test
    public void getValueTest() {
        Stock stock = mock(Stock.class, withSettings().defaultAnswer(CALLS_REAL_METHODS));
        when(stock.getPrice()).thenReturn(100.00);
        when(stock.getQuantity()).thenReturn(200);
        double value = stock.getValue();

        assertEquals("Stock value not correct", 100.00 * 200, value, .00001);
    }
}

The call to Stock stock = mock(Stock.class); calls org.mockito.Mockito.mock(Class<T>) which looks like this:

 public static <T> T mock(Class<T> classToMock) {
    return mock(classToMock, withSettings().defaultAnswer(RETURNS_DEFAULTS));
}

The docs of the value RETURNS_DEFAULTS tell:

/**
 * The default <code>Answer</code> of every mock <b>if</b> the mock was not stubbed.
 * Typically it just returns some empty value. 
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations. 
 * <p>
 * This implementation first tries the global configuration. 
 * If there is no global configuration then it uses {@link ReturnsEmptyValues} (returns zeros, empty collections, nulls, etc.)
 */

It looks like there is no difference, for uses each underneath.

Like Bayard says, each is more idiomatic. It hides more from you and doesn't require special language features. Per Telemachus's Comment

for .. in .. sets the iterator outside the scope of the loop, so

for a in [1,2]
  puts a
end

leaves a defined after the loop is finished. Where as each doesn't. Which is another reason in favor of using each, because the temp variable lives a shorter period.

Make an exception handler like this,

private int ConvertIntoNumeric(String xVal)
{
 try
  { 
     return Integer.parseInt(xVal);
  }
 catch(Exception ex) 
  {
     return 0; 
  }
}

.
.
.
.

int xTest = ConvertIntoNumeric("N/A");  //Will return 0

@SilverLight.. This is clearly an issue with a Database object. It can be a badly written query, or missing indexes. But as of now I won't suggest you to increase the timeout without investigating the issue with your Database objects

NovinMedia.Data.DbObject.RunProcedure(String storedProcName, IDataParameter[] parameters, Int32& rowsAffected) +209

Put a breakpoint on this line of code to findout the procedure name and then optimise the procedure by looking at its execution plan.

I cannot help you more till the time you post details about the stored procedure.

Tomcat does log the stacktrace, but it is not always clear where the log files are, when tomcat is started from an IDE. When I start it from IntelliJ, CATALINA_BASE is set to ${home}/.IntelliJIdea10/system/tomcat/Unnamed_r6-idea, and the log files are in in [CATALINA_BASE]/logs.

To see the logs, either locate the log files, or edit [CATALINA_HOME]/conf/logging.properties to direct tomcat logger output to console. Below I added a second handler to the default tomcat configuration:

 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

Now the full stacktrace appears in the IntelliJ output:

 Dec 27, 2011 12:02:45 PM org.apache.catalina.core.StandardContext filterStart
 SEVERE: Exception starting filter filterChainProxy
 org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'filterChainProxy' is defined   at
 org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:529)
 . . .

I have just created the function with the same names to convert and overwrite to the new one php7:

$host =     "your host";      
$un = "username";    
$pw = "password";       
$db = "database"; 

$MYSQLI_CONNECT = mysqli_connect($host, $un, $pw, $db);

function mysql_query($q) {
    global $MYSQLI_CONNECT;
    return mysqli_query($MYSQLI_CONNECT,$q);
}

function mysql_fetch_assoc($q) {
    return mysqli_fetch_assoc($q);
}

function mysql_fetch_array($q){
    return mysqli_fetch_array($q , MYSQLI_BOTH);
}

function mysql_num_rows($q){
    return mysqli_num_rows($q);
}

function mysql_insert_id() {
    global $MYSQLI_CONNECT;
    return mysqli_insert_id($MYSQLI_CONNECT);
}

function mysql_real_escape_string($q) {
    global $MYSQLI_CONNECT;
    return mysqli_real_escape_string($MYSQLI_CONNECT,$q);
}

It works for me , I hope it will work for you all , if I mistaken , correct me.

How do I keep looping through until the len(new_list) = len(data_list)

while len(new_list) != len(data_list):
    # ...

Maybe like this?

And no, it’s not necessary to create a new list; most sorting algorithms work by changing the list in place.

What you probably trying to do is Selection sort with a separate list. See the Wikipedia article for more information about that sorting algorithm and you’ll see how it works with a single list, and how efficient it is (spoiler: it isn’t).

This is commonly caused by running out of file descriptors.

There is the systems total file descriptor limit, what do you get from the command:

sysctl fs.file-nr

This returns counts of file descriptors:

<in_use> <unused_but_allocated> <maximum>

To find out what a users file descriptor limit is run the commands:

sudo su - <username>
ulimit -Hn

To find out how many file descriptors are in use by a user run the command:

sudo lsof -u <username> 2>/dev/null | wc -l

So now if you are having a system file descriptor limit issue you will need to edit your /etc/sysctl.conf file and add, or modify it it already exists, a line with fs.file-max and set it to a value large enough to deal with the number of file descriptors you need and reboot.

fs.file-max = 204708

you can do it better with two datagridview, you add the same datasource , hide the headers of the second, set the height of the second = to the height of the rows of the first, turn off all resizable atributes of the second, synchronize the scrollbars of both, only horizontal, put the second on the botton of the first etc.

take a look:

   dgv3.ColumnHeadersVisible = false;
   dgv3.Height = dgv1.Rows[0].Height;
   dgv3.Location = new Point(Xdgvx, this.dgv1.Height - dgv3.Height - SystemInformation.HorizontalScrollBarHeight);
   dgv3.Width = dgv1.Width;

   private void dgv1_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
            {
                dgv3.HorizontalScrollingOffset = e.NewValue;
            }
        }

Regular Expression for 0 to 100 with the decimal point.

^100(\.[0]{1,2})?|([0-9]|[1-9][0-9])(\.[0-9]{1,2})?$

you can do it with visual Basic, put a Webbrowser control on the form, load an html that opens a popup with Location=no and it will open a new browser without address bar. Probably not what you are looking for but just thought throw it in :)

// GET: api/GetStudent

public Response Get() {
    return StoredProcedure.GetStudent();
}

public static Response GetStudent() {
    using (var db = new dal()) {
        var student = db.Database.SqlQuery<GetStudentVm>("GetStudent").ToList();
        return new Response {
            Sucess = true,
            Message = student.Count() + " Student found",
            Data = student
        };
    }
}

You may put an inner div in the container that is enough wide to hold all the floated divs.

#container {_x000D_
  background-color: red;_x000D_
  overflow: hidden;_x000D_
  width: 200px;_x000D_
}_x000D_
_x000D_
#inner {_x000D_
  overflow: hidden;_x000D_
  width: 2000px;_x000D_
}_x000D_
_x000D_
.child {_x000D_
  float: left;_x000D_
  background-color: blue;_x000D_
  width: 50px;_x000D_
  height: 50px;_x000D_
}

<div id="container">_x000D_
  <div id="inner">_x000D_
    <div class="child"></div>_x000D_
    <div class="child"></div>_x000D_
    <div class="child"></div>_x000D_
  </div>_x000D_
</div>

Actually, you will have to use the "?" instead of "&" for your first parameter only. If you use more than one parameter, you will then have to add "&" to the chain.

For instance, if you want to add autoplay and closed captioning, you will have to add this portion to your embedded video URL: ?autoplay=1&cc_load_policy=1.

It would look like this:

<iframe width="420" height="315" src="http://www.youtube.com/embed/
oHg5SJYRHA0?autoplay=1&cc_load_policy=1" frameborder="0"
allowfullscreen></iframe>

Strings are always modelled as immutable (atleast in heigher level languages python/java/javascript/Scala/Objective-C).

So any string operations like concatenation, replacements always returns a new string which contains intended value, whereas the original string will still be same.

Regex for Facebook-like validation:

public static final String REGEX_EMAIL_VALIDATION = "^[\\w-\\+]+(\\.[\\w]+)*@[\\w-]+(\\.[\\w]+)*(\\.[a-zA-Z]{2,})$";

Dto for Unit tests(with Lombok):

@Data
@Accessors(chain = true)
@FieldDefaults(level = AccessLevel.PRIVATE)
public class UserCreateDto {

    @NotNull
    @Pattern(regexp = REGEX_EMAIL_VALIDATION)
    @Size(min = 1, max = 254)
    String email;
}

Valid/invalid emails below with Unit tests:

public class UserCreateValidationDtoTest {

private static final String[] VALID_EMAILS = new String[]{"[email protected]", "[email protected]",
        "[email protected]", "[email protected]", "[email protected]",
        "[email protected]", "[email protected]", "[email protected]",
        "[email protected]", "[email protected]", "[email protected]"};
private static final String[] INVALID_EMAILS = new String[]{"[email protected]", "email@111",
        "email", "[email protected]", "email123@gmail.", "[email protected]", "[email protected]",
        "[email protected]", "email()*@gmAil.com", "eEmail()*@gmail.com", "email@%*.com", "[email protected]",
        "[email protected]", "email@[email protected]", "[email protected]."};
private Validator validator;

@Before
public void setUp() throws Exception {
    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    validator = factory.getValidator();
}

@Test
public void emailValidationShouldBeValid() throws Exception {
    Arrays.stream(VALID_EMAILS)
            .forEach(email -> {
                        Set<ConstraintViolation<UserCreateDto>> violations = validateEmail(
                                new UserCreateDto().setEmail(email));
                        System.out.println("Email: " + email + ", violations: " + violations);
                        Assert.assertTrue(violations.isEmpty());
                    }
            );
}

@Test
public void emailValidationShouldBeNotValid() throws Exception {
    Arrays.stream(INVALID_EMAILS)
            .forEach(email -> {
                        Set<ConstraintViolation<UserCreateDto>> violations = validateEmail(
                                new UserCreateDto().setEmail(email));
                        System.out.println("Email: " + email + ", violations: " + violations);
                        Assert.assertTrue(!violations.isEmpty());
                    }
            );
}


private Set<ConstraintViolation<UserCreateDto>> validateEmail(UserCreateDto user) {
    String emailFieldName = "email";
    return validator.validateProperty(user, emailFieldName);
}

}

Add a unique id to all your instances, i.e.

public interface Idable {
  int id();
}

public class IdGenerator {
  private static int id = 0;
  public static synchronized int generate() { return id++; }
}

public abstract class AbstractSomething implements Idable {
  private int id;
  public AbstractSomething () {
    this.id = IdGenerator.generate();
  }
  public int id() { return id; }
}

Extend from AbstractSomething and query this property. Will be safe inside a single vm (assuming no game playing with classloaders to get around statics).

Did you see this? If I haven't misunderstand that answer, you may try to create a new virtualenv on top of the old one. You just need to know which python is going to use your virtualenv (you will need to see your virtualenv version).

If your virtualenv is installed with the same python version of the old one and upgrading your virtualenv package is not an option, you may want to read this in order to install a virtualenv with the python version you want.

EDIT

I've tested this approach (the one that create a new virtualenv on top of the old one) and it worked fine for me. I think you may have some problems if you change from python 2.6 to 2.7 or 2.7 to 3.x but if you just upgrade inside the same version (staying at 2.7 as you want) you shouldn't have any problem, as all the packages are held in the same folders for both python versions (2.7.x and 2.7.y packages are inside your_env/lib/python2.7/).

If you change your virtualenv python version, you will need to install all your packages again for that version (or just link the packages you need into the new version packages folder, i.e: your_env/lib/python_newversion/site-packages)

Here for usefulness... some code for getting the values into a list, which converts the enum into readable form for the text

public class KeyValuePair
  {
    public string Key { get; set; }

    public string Name { get; set; }

    public int Value { get; set; }

    public static List<KeyValuePair> ListFrom<T>()
    {
      var array = (T[])(Enum.GetValues(typeof(T)).Cast<T>());
      return array
        .Select(a => new KeyValuePair
          {
            Key = a.ToString(),
            Name = a.ToString().SplitCapitalizedWords(),
            Value = Convert.ToInt32(a)
          })
          .OrderBy(kvp => kvp.Name)
         .ToList();
    }
  }

.. and the supporting System.String extension method:

/// <summary>
/// Split a string on each occurrence of a capital (assumed to be a word)
/// e.g. MyBigToe returns "My Big Toe"
/// </summary>
public static string SplitCapitalizedWords(this string source)
{
  if (String.IsNullOrEmpty(source)) return String.Empty;
  var newText = new StringBuilder(source.Length * 2);
  newText.Append(source[0]);
  for (int i = 1; i < source.Length; i++)
  {
    if (char.IsUpper(source[i]))
      newText.Append(' ');
    newText.Append(source[i]);
  }
  return newText.ToString();
}

REST is an architecture invented by Roy Fielding and described in his dissertation Architectural Styles and the Design of Network-based Software Architectures. Roy is also the main author of HTTP - the protocol that defines document transfer over the World Wide Web. HTTP is a RESTful protocol. When developers talk about "using REST Web services" it is probably more accurate to say "using HTTP."

SOAP is a XML-based protocol that tunnels inside an HTTP request/response, so even if you use SOAP, you are using REST too. There is some debate over whether SOAP adds any significant functionality to basic HTTP.

Before authoring a Web service, I would recommend studying HTTP. Odds are your requirements can be implemented with functionality already defined in the spec, so other protocols won't be needed.

var obj = { a: 1, b: undefined, c: 3 }

To remove undefined props in an object we use like this

JSON.parse(JSON.stringify(obj));

Output: {a: 1, c: 3}

Then tell read.table not to use row.names:

systems <- read.table("http://getfile.pl?test.csv", 
                      header=TRUE, sep=",", row.names=NULL)

and now your rows will simply be numbered.

Also look at read.csv which is a wrapper for read.table which already sets the sep=',' and header=TRUE arguments so that your call simplifies to

systems <- read.csv("http://getfile.pl?test.csv", row.names=NULL)

How about this? (jsFiddle link)

The error implies that this subquery is returning more than 1 row:

(Select Supplier_Item.Price from Supplier_Item,orderdetails,Supplier where Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID )

You probably don't want to include the orderdetails and supplier tables in the subquery, because you want to reference the values selected from those tables in the outer query. So I think you want the subquery to be simply:

(Select Supplier_Item.Price from Supplier_Item where Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID )

I suggest you read up on correlated vs. non-correlated subqueries.

u can simply use "width" attribute of "style" to change the length of the dropdown box

<select class="my_dropdown" id="my_dropdown" style="width:APPROPRIATE WIDTH IN PIXLES">

<option value="2">short</option>
</select>

e.g.

style="width:200px"

Indexing in python starting from 0. You wrote [1:] this would not return you a first char in any case - this will return you a rest(except first char) of string.

If you have the following structure:

mylist = ['base', 'sample', 'test']

And want to get fist char for the first one string(item):

myList[0][0]
>>> b

If all first chars:

[x[0] for x in myList]
>>> ['b', 's', 't']    

If you have a text:

text = 'base sample test'
text.split()[0][0]
>>> b

If you are Clion/anyOtherJetBrainsIDE user, and yourFile.exe cause this problem, just delete it and let the app create and link it with libs from a scratch. It helps.

First of all you have to fetch the remote repository:

git fetch remoteName

Than you can create the new branch and set it up to track the remote branch you want:

git checkout -b newLocalBranch remoteName/remoteBranch

You can also use "git branch --track" instead of "git checkout -b" as max specified.

git branch --track newLocalBranch remoteName/remoteBranch
