well i found a solution to this problem for who want to work with xCode 4. All what you have to do is importing frameworks from the SimulatorSDK folder /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks

i don't know if it works when you try to test your app on a real iDevice, but i'm sure that it works on simulator.

ENJOY

NSDecimalNumber *myNumber = [NSDecimalNumber decimalNumberWithString:@"123.45"];
NSLog(@"My Number : %@",myNumber);

If you want to get the content without the html tags from the web page (HTML document) , then use this code inside the UIWebViewDidfinishLoading delegate method.

  NSString *myText = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"];

Using Select2 4.0 with Meteor you can do something like this:

Template.TemplateName.rendered = ->

  $("#select2-el").select2({
    data  : Session.get("select2Data")
  })

  @autorun ->

    # Clear the existing list options. 
    $("#select2-el").select2().empty()

    # Re-create with new options.
    $("#select2-el").select2({
      data  : Session.get("select2Data")
    })

What's happening:

1. When Template is rendered...
2. Init a select2 control with data from Session.
3. @autorun (this.autorun) function runs every time the value of Session.get("select2Data") changes.
4. Whenever Session changes, clear existing select2 options and re-create with new data.

This works for any reactive data source - such as a Collection.find().fetch() - not just Session.get().

NOTE: as of Select2 version 4.0 you must remove existing options before adding new onces. See this GitHub Issue for details. There is no method to 'update the options' without clearing the existing ones.

The above is coffeescript. Very similar for Javascript.

I agree that StringTokenizer is overkill here. Actually I tried out the suggestions above and took the time.

My test was fairly simple: create a StringBuilder with about a million characters, convert it to a String, and traverse each of them with charAt() / after converting to a char array / with a CharacterIterator a thousand times (of course making sure to do something on the string so the compiler can't optimize away the whole loop :-) ).

The result on my 2.6 GHz Powerbook (that's a mac :-) ) and JDK 1.5:

• Test 1: charAt + String --> 3138msec
• Test 2: String converted to array --> 9568msec
• Test 3: StringBuilder charAt --> 3536msec
• Test 4: CharacterIterator and String --> 12151msec

As the results are significantly different, the most straightforward way also seems to be the fastest one. Interestingly, charAt() of a StringBuilder seems to be slightly slower than the one of String.

BTW I suggest not to use CharacterIterator as I consider its abuse of the '\uFFFF' character as "end of iteration" a really awful hack. In big projects there's always two guys that use the same kind of hack for two different purposes and the code crashes really mysteriously.

Here's one of the tests:

    int count = 1000;
    ...

    System.out.println("Test 1: charAt + String");
    long t = System.currentTimeMillis();
    int sum=0;
    for (int i=0; i<count; i++) {
        int len = str.length();
        for (int j=0; j<len; j++) {
            if (str.charAt(j) == 'b')
                sum = sum + 1;
        }
    }
    t = System.currentTimeMillis()-t;
    System.out.println("result: "+ sum + " after " + t + "msec");

Use the navbar component and add .navbar-fixed-bottom class:

<div class="navbar navbar-fixed-bottom"></div>

add body

  { padding-bottom: 70px; }

You could use:

jQuery('input[type="date"]').live('click', function(e) {e.preventDefault();}).datepicker();

use

struct arg_struct *args = (struct arg_struct *)arguments;

in place of

struct arg_struct *args = (struct arg_struct *)args;

Since you have not mentioned what needs to be copied, I have left that section empty in the code below.

Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.

This will get you started. I have commented the code so that you will not face any problem understanding it.

First paste the below mentioned code in the outlook module.

Then

1. Click on Tools~~>Rules and Alerts
2. Click on "New Rule"
3. Click on "start from a blank rule"
4. Select "Check messages When they arrive"
5. Under conditions, click on "with specific words in the subject"
6. Click on "specific words" under rules description.
7. Type the word that you want to check in the dialog box that pops up and click on "add".
8. Click "Ok" and click next
9. Select "move it to specified folder" and also select "run a script" in the same box
10. In the box below, specify the specific folder and also the script (the macro that you have in module) to run.
11. Click on finish and you are done.

When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

FOLLOWUP

To extract the contents from your email body, you can split it using SPLIT() and then parsing out the relevant information from it. See this example

Dim MyAr() As String

MyAr = Split(olMail.body, vbCrLf)

For i = LBound(MyAr) To UBound(MyAr)
    '~~> This will give you the contents of your email
    '~~> on separate lines
    Debug.Print MyAr(i)
Next i

like so:

long[,] arr = new long[4, 4] { { 0, 0, 0, 0 }, { 1, 1, 1, 1 }, { 0, 0, 0, 0 }, { 1, 1, 1, 1 } };

var rowCount = arr.GetLength(0);
var colCount = arr.GetLength(1);
for (int row = 0; row < rowCount; row++)
{
    for (int col = 0; col < colCount; col++)               
        Console.Write(String.Format("{0}\t", arr[row,col]));
    Console.WriteLine();
} 

As long as you do not use 1.4 version, you can use explicit annotation:

example:

@Query("select count(e) from Product e where e.area.code = ?1")
long countByAreaCode(String code);

When granting a user access to a database there are a few considerations to be made with advantages and disadvantages in terms of usability and security. Here we have two options for authenticating and granting permission to users. The first is by giving everyone the sa (systems admin) account access and then restricting the permissions manually by retaining a list of the users in which you can grant or deny permissions as needed. This is also known as the SQL authentication method. There are major security flaws in this method, as listed below. The second and better option is to have the Active Directory (AD) handle all the necessary authentication and authorization, also known as Windows authentication. Once the user logs in to their computer the application will connect to the database using those Windows login credentials on the operating system.

The major security issue with using the SQL option is that it violates the principle of least privilege (POLP) which is to only give the user the absolutely necessary permissions they need and no more. By using the sa account you present serious security flaws. The POLP is violated because when the application uses the sa account they have access to the entire database server. Windows authentication on the other hand follows the POLP by only granting access to one database on the server.

The second issue is that there is no need for every instance of the application to have the admin password. This means any application is a potential attack point for the entire server. Windows only uses the Windows credentials to login to the SQL Server. The Windows passwords are stored in a repository as opposed to the SQL database instance itself and the authentication takes place internally within Windows without having to store sa passwords on the application.

A third security issue arises by using the SQL method involves passwords. As presented on the Microsoft website and various security forums, the SQL method doesn’t’ enforce password changing or encryption, rather they are sent as clear text over the network. And the SQL method doesn’t lockout after failing attempts thus allowing a prolonged attempt to break in. Active Directory however, uses Kerberos protocol to encrypt passwords while employing as well a password change system and lockout after failing attempts.

There are efficiency disadvantages as well. Since you will be requiring the user to enter the credentials every time they want to access the database users may forget their credentials.

If a user being removed you would have to remove his credentials from every instance of the application. If you have to update the sa admin password you would have to update every instance of the SQL server. This is time consuming and unsafe, it leaves open the possibility of a dismissed user retaining access to the SQL Server. With the Windows method none of these concerns arise. Everything is centralized and handled by the AD.

The only advantages of using the SQL method lie in its flexibility. You are able to access it from any operating system and network, even remotely. Some older legacy systems as well as some web-based applications may only support sa access.

The AD method also provides time-saving tools such as groups to make it easier to add and remove users, and user tracking ability.

Even if you manage to correct these security flaws in the SQL method, you would be reinventing the wheel. When considering the security advantages provided by Windows authentication, including password policies and following the POLP, it is a much better choice over the SQL authentication. Therefore it is highly recommended to use the Windows authentication option.

This is more readable and good practice too.

With Android's Newer Version >= API 16 use finishAffinity()

approach is suitable for >= API 16.

Intent mIntent = new Intent(mContext,MainActivity.class);
finishAffinity();
startActivity(mIntent);

• Its is same as starting new Activity, and clear all stack.
• OR Restart to MainActivity/FirstActivity.

A simple way is to use a configuration data object, save it as an XML file with the name of the application in the local Folder and on startup read it back.

Here is an example to store the position and size of a form.

The configuration dataobject is strongly typed and easy to use:

[Serializable()]
public class CConfigDO
{
    private System.Drawing.Point m_oStartPos;
    private System.Drawing.Size m_oStartSize;

    public System.Drawing.Point StartPos
    {
        get { return m_oStartPos; }
        set { m_oStartPos = value; }
    }

    public System.Drawing.Size StartSize
    {
        get { return m_oStartSize; }
        set { m_oStartSize = value; }
    }
}

A manager class for saving and loading:

public class CConfigMng
{
    private string m_sConfigFileName = System.IO.Path.GetFileNameWithoutExtension(System.Windows.Forms.Application.ExecutablePath) + ".xml";
    private CConfigDO m_oConfig = new CConfigDO();

    public CConfigDO Config
    {
        get { return m_oConfig; }
        set { m_oConfig = value; }
    }

    // Load configuration file
    public void LoadConfig()
    {
        if (System.IO.File.Exists(m_sConfigFileName))
        {
            System.IO.StreamReader srReader = System.IO.File.OpenText(m_sConfigFileName);
            Type tType = m_oConfig.GetType();
            System.Xml.Serialization.XmlSerializer xsSerializer = new System.Xml.Serialization.XmlSerializer(tType);
            object oData = xsSerializer.Deserialize(srReader);
            m_oConfig = (CConfigDO)oData;
            srReader.Close();
        }
    }

    // Save configuration file
    public void SaveConfig()
    {
        System.IO.StreamWriter swWriter = System.IO.File.CreateText(m_sConfigFileName);
        Type tType = m_oConfig.GetType();
        if (tType.IsSerializable)
        {
            System.Xml.Serialization.XmlSerializer xsSerializer = new System.Xml.Serialization.XmlSerializer(tType);
            xsSerializer.Serialize(swWriter, m_oConfig);
            swWriter.Close();
        }
    }
}

Now you can create an instance and use in your form's load and close events:

    private CConfigMng oConfigMng = new CConfigMng();

    private void Form1_Load(object sender, EventArgs e)
    {
        // Load configuration
        oConfigMng.LoadConfig();
        if (oConfigMng.Config.StartPos.X != 0 || oConfigMng.Config.StartPos.Y != 0)
        {
            Location = oConfigMng.Config.StartPos;
            Size = oConfigMng.Config.StartSize;
        }
    }

    private void Form1_FormClosed(object sender, FormClosedEventArgs e)
    {
        // Save configuration
        oConfigMng.Config.StartPos = Location;
        oConfigMng.Config.StartSize = Size;
        oConfigMng.SaveConfig();
    }

And the produced XML file is also readable:

<?xml version="1.0" encoding="utf-8"?>
<CConfigDO xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <StartPos>
    <X>70</X>
    <Y>278</Y>
  </StartPos>
  <StartSize>
    <Width>253</Width>
    <Height>229</Height>
  </StartSize>
</CConfigDO>

DECLARE @STR VARCHAR(400)

DECLARE @specialchars VARCHAR(50) = '%[~,@,#,$,%,&,*,(,),!^?:]%'

SET @STR = '1, 45 4,3 68.00-'

WHILE PATINDEX( @specialchars, @STR ) > 0

---Remove special characters using Replace function

SET @STR = Replace(Replace(REPLACE( @STR, SUBSTRING( @STR, PATINDEX( @specialchars, @STR ), 1 ),''),'-',''), ' ','')

SELECT @STR

This will work for URL encoded strings too.

^(https?)(:\/\/|(\%3A%2F%2F))

Via Jquery:

$(location).attr('href','http://example.com/Registration/Success/');

Nested classes are just like regular classes, but:

• they have additional access restriction (as all definitions inside a class definition do),
• they don't pollute the given namespace, e.g. global namespace. If you feel that class B is so deeply connected to class A, but the objects of A and B are not necessarily related, then you might want the class B to be only accessible via scoping the A class (it would be referred to as A::Class).

Some examples:

Publicly nesting class to put it in a scope of relevant class

Assume you want to have a class SomeSpecificCollection which would aggregate objects of class Element. You can then either:

1. declare two classes: SomeSpecificCollection and Element - bad, because the name "Element" is general enough in order to cause a possible name clash

2. introduce a namespace someSpecificCollection and declare classes someSpecificCollection::Collection and someSpecificCollection::Element. No risk of name clash, but can it get any more verbose?

3. declare two global classes SomeSpecificCollection and SomeSpecificCollectionElement - which has minor drawbacks, but is probably OK.

4. declare global class SomeSpecificCollection and class Element as its nested class. Then:

   • you don't risk any name clashes as Element is not in the global namespace,
   • in implementation of SomeSpecificCollection you refer to just Element, and everywhere else as SomeSpecificCollection::Element - which looks +- the same as 3., but more clear
   • it gets plain simple that it's "an element of a specific collection", not "a specific element of a collection"
   • it is visible that SomeSpecificCollection is also a class.

In my opinion, the last variant is definitely the most intuitive and hence best design.

Let me stress - It's not a big difference from making two global classes with more verbose names. It just a tiny little detail, but imho it makes the code more clear.

Introducing another scope inside a class scope

This is especially useful for introducing typedefs or enums. I'll just post a code example here:

class Product {
public:
    enum ProductType {
        FANCY, AWESOME, USEFUL
    };
    enum ProductBoxType {
        BOX, BAG, CRATE
    };
    Product(ProductType t, ProductBoxType b, String name);

    // the rest of the class: fields, methods
};

One then will call:

Product p(Product::FANCY, Product::BOX);

But when looking at code completion proposals for Product::, one will often get all the possible enum values (BOX, FANCY, CRATE) listed and it's easy to make a mistake here (C++0x's strongly typed enums kind of solve that, but never mind).

But if you introduce additional scope for those enums using nested classes, things could look like:

class Product {
public:
    struct ProductType {
        enum Enum { FANCY, AWESOME, USEFUL };
    };
    struct ProductBoxType {
        enum Enum { BOX, BAG, CRATE };
    };
    Product(ProductType::Enum t, ProductBoxType::Enum b, String name);

    // the rest of the class: fields, methods
};

Then the call looks like:

Product p(Product::ProductType::FANCY, Product::ProductBoxType::BOX);

Then by typing Product::ProductType:: in an IDE, one will get only the enums from the desired scope suggested. This also reduces the risk of making a mistake.

Of course this may not be needed for small classes, but if one has a lot of enums, then it makes things easier for the client programmers.

In the same way, you could "organise" a big bunch of typedefs in a template, if you ever had the need to. It's a useful pattern sometimes.

The PIMPL idiom

The PIMPL (short for Pointer to IMPLementation) is an idiom useful to remove the implementation details of a class from the header. This reduces the need of recompiling classes depending on the class' header whenever the "implementation" part of the header changes.

It's usually implemented using a nested class:

X.h:

class X {
public:
    X();
    virtual ~X();
    void publicInterface();
    void publicInterface2();
private:
    struct Impl;
    std::unique_ptr<Impl> impl;
}

X.cpp:

#include "X.h"
#include <windows.h>

struct X::Impl {
    HWND hWnd; // this field is a part of the class, but no need to include windows.h in header
    // all private fields, methods go here

    void privateMethod(HWND wnd);
    void privateMethod();
};

X::X() : impl(new Impl()) {
    // ...
}

// and the rest of definitions go here

This is particularly useful if the full class definition needs the definition of types from some external library which has a heavy or just ugly header file (take WinAPI). If you use PIMPL, then you can enclose any WinAPI-specific functionality only in .cpp and never include it in .h.

Try this

public int GetFirstDigit(int number) {
  if ( number < 10 ) {
    return number;
  }
  return GetFirstDigit ( (number - (number % 10)) / 10);
}

EDIT

Several people have requested the loop version

public static int GetFirstDigitLoop(int number)
{
    while (number >= 10)
    {
        number = (number - (number % 10)) / 10;
    }
    return number;
}

preg_replace('/[^a-zA-Z0-9\s]/', '',$string) this is using for removing special character only rather than space between the strings.

The window.open will open url in new browser Tab

The window.location.href will open url in current Tab (instead you can use location)

Here is example fiddle (in SO snippets window.open doesn't work)

var url = 'https://example.com';_x000D_
_x000D_
function go1() { window.open(url) }_x000D_
_x000D_
function go2() { window.location.href = url }_x000D_
_x000D_
function go3() { location = url }

<div>Go by:</div>_x000D_
<button onclick="go1()">window.open</button>_x000D_
<button onclick="go2()">window.location.href</button>_x000D_
<button onclick="go3()">location</button>

The easiest solution in Bash:

$ s='"abc"'
$ echo $s
"abc"
$ echo "${s:1:-1}"
abc

This is called substring expansion (see Gnu Bash Manual and search for ${parameter:offset:length}). In this example it takes the substring from s starting at position 1 and ending at the second last position. This is due to the fact that if length is a negative value it is interpreted as a backwards running offset from the end of parameter.

In swift 4.0

Create a delegate on class that need to send some data or provide some functionality to other classes

Like

protocol GetGameStatus {
    var score: score { get }
    func getPlayerDetails()
}

After that in the class that going to confirm to this delegate

class SnakesAndLadders: GetGameStatus {
    func getPlayerDetails() {

 }
}

#! /bin/bash
timeout=10
interval=1
delay=3
(
    ((t = timeout)) || :

    while ((t > 0)); do
        echo "$t"
        sleep $interval
        # Check if the process still exists.
        kill -0 $$ 2> /dev/null || exit 0
        ((t -= interval)) || :
    done

    # Be nice, post SIGTERM first.
    { echo SIGTERM to $$ ; kill -s TERM $$ ; sleep $delay ; kill -0 $$ 2> /dev/null && { echo SIGKILL to $$ ; kill -s KILL $$ ; } ; }
) &

exec "$@"

For python 3.3

from datetime import datetime, timedelta
futuredate = datetime.now() + timedelta(days=10)

If you invoke the shell with script-file, db address, and --quiet arguments, you can redirect the output (made with print() for example) to a file:

mongo localhost/mydatabase --quiet myScriptFile.js > output 

Try this one out

public void getObjectList(){
        System.out.println("Listing objects");
        ObjectListing objectListing = s3.listObjects(new ListObjectsRequest()
                .withBucketName(bucketName)
                .withPrefix("ads"));
        for (S3ObjectSummary objectSummary : objectListing.getObjectSummaries()) {
            System.out.println(" - " + objectSummary.getKey() + "  " +
                               "(size = " + objectSummary.getSize() + ")");
        }
    }

You can all the objects within the bucket with specific prefix.

varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.

The spaces are significant. You created a variable named 'location ' with a value of
' "bob"'. Note - enclosing single quotes were added to show location of space.

If you want quotes in your value, then your code should look like

set location="bob"

If you don't want quotes, then your code should look like

set location=bob

Or better yet

set "location=bob"

The last syntax prevents inadvertent trailing spaces from getting in the value, and also protects against special characters like & | etc.

As Alex Gray points out in a comment above, "all of the corresponding IDs are actually on the extensions page within the browser".

However, you must click the Developer Mode checkbox at top of Extensions page to see them.

You can use Calendar's method

func date(byAdding component: Calendar.Component, value: Int, to date: Date, wrappingComponents: Bool = default) -> Date?

to add any Calendar.Component to any Date. You can create a Date extension to add x minutes to your UIDatePicker's date:

Xcode 8 and Xcode 9 • Swift 3.0 and Swift 4.0

extension Date {
    func adding(minutes: Int) -> Date {
        return Calendar.current.date(byAdding: .minute, value: minutes, to: self)!
    }
}

Then you can just use the extension method to add minutes to the sender (UIDatePicker):

let section1 = sender.date.adding(minutes: 5)
let section2 = sender.date.adding(minutes: 10)

Playground testing:

Date().adding(minutes: 10)  //  "Jun 14, 2016, 5:31 PM"

If you want to know how much numbers the array have, you want to know the array length. The function sizeof(var) in C gives you the bytes in the computer memory. So if you know the memory the int occupy you can do like this:

int arraylength(int array[]) {
    return sizeof(array) / sizeof(int); // Size of the Array divided by the int size
}

As of CMake Wiki:

CMAKE_BINARY_DIR if you are building in-source, this is the same as CMAKE_SOURCE_DIR, otherwise this is the top level directory of your build tree

Compare these two variables to determine if out-of-source build was started

You can simply type Q: and that should solve your problem.

This depends on where you want the error message be stored.

You can do the following:

echo "Error!" > logfile.log
exit 125

Or the following:

echo "Error!" 1>&2
exit 64

When you raise an exception you stop the program's execution.

You can also use something like exit xxx where xxx is the error code you may want to return to the operating system (from 0 to 255). Here 125 and 64 are just random codes you can exit with. When you need to indicate to the OS that the program stopped abnormally (eg. an error occurred), you need to pass a non-zero exit code to exit.

As @chepner pointed out, you can do exit 1, which will mean an unspecified error.

There is a misunderstanding here with respect to what a "fork" is. A fork is in fact nothing more than a set of per-user branches. When you push to a fork you actually do push to the original repository, because that is the ONLY repository.

You can try this out by pushing to a fork, noting the commit and then going to the original repository and using the commit ID, you'll see that the commit is "in" the original repository.

This makes a lot of sense, but it is far from obvious (I only discovered this accidentally recently).

When John forks repository SuperProject what seems to actually happen is that all branches in the source repository are replicated with a name like "John.master", "John.new_gui_project", etc.

GitHub "hides" the "John." from us and gives us the illusion we have our own "copy" of the repository on GitHub, but we don't and nor is one even needed.

So my fork's branch "master" is actually named "Korporal.master", but the GitHub UI never reveals this, showing me only "master".

This is pretty much what I think goes on under the hood anyway based on stuff I've been doing recently and when you ponder it, is very good design.

For this reason I think it would be very easy for Microsoft to implement Git forks in their Visual Studio Team Services offering.

Your question is: "How can I see exactly what happened in the someFunction() that caused the exception to happen?"

It seems to me that you are not asking about how to handle unforeseen exceptions in production code (as many answers assumed), but how to find out what is causing a particular exception during development.

The easiest way is to use a debugger that can stop where the uncaught exception occurs, preferably not exiting, so that you can inspect the variables. For example, PyDev in the Eclipse open source IDE can do that. To enable that in Eclipse, open the Debug perspective, select Manage Python Exception Breakpoints in the Run menu, and check Suspend on uncaught exceptions.

This problem becomes apparent when you try to host a react app in github pages.

How I fixed this,

In in my main application file, called app.tsx, where I include the router. I set the basename, eg, <BrowserRouter basename="/Seans-TypeScript-ReactJS-Redux-Boilerplate/">

Note that it is a relative url, this completely simplifies the ability to run locally and hosted. The basename value, matches the repository title on GitHub. This is the path that GitHub pages will auto create.

That is all I needed to do.

See working example hosted on GitHub pages at

https://sean-bradley.github.io/Seans-TypeScript-ReactJS-Redux-Boilerplate/

The only case I could imagine is, that you run this on a webkit browser like Chrome or Safari and your return value in responseText, contains a string value.

In that constelation, the value cannot be displayed (it would get blank)

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

My point here is, that I expect a wrong/double encoded string value. Webkit browsers are more strict on the type = number. If there is "only" a white-space issue, you can try to implicitly call the Number() constructor, like

document.getElementById("points").value = +request.responseText;

For Python2.7 - modifying MYGz's answer to not strip milliseconds:

from datetime import datetime

d = datetime.strptime("20.12.2016 09:38:42,76", "%d.%m.%Y %H:%M:%S,%f").strftime('%s.%f')
d_in_ms = int(float(d)*1000)
print(d_in_ms)

print(datetime.fromtimestamp(float(d)))

Output:

1482248322760
2016-12-20 09:38:42.760000

If you do not need the original list of dictionaries, you could modify it in-place with sort() method using a custom key function.

Key function:

def get_name(d):
    """ Return the value of a key in a dictionary. """

    return d["name"]

The list to be sorted:

data_one = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]

Sorting it in-place:

data_one.sort(key=get_name)

If you need the original list, call the sorted() function passing it the list and the key function, then assign the returned sorted list to a new variable:

data_two = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]
new_data = sorted(data_two, key=get_name)

Printing data_one and new_data.

>>> print(data_one)
[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]
>>> print(new_data)
[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]

So, with customer we create this crazy regex:

(^$)|(^([^\-!#\$%&\(\)\*,\./:;\?@\[\\\]_\{\|\}¨?“”€\+<=>§°\d\s¤®™©]| )+$)

Sorry, much late to the party, but I'll add here that if you wanted to capture processes with names identical to your search string, you could do

pgrep -x PROCESS_NAME

-x          Require an exact match of the process name, or argument list if -f is given.
             The default is to match any substring.

This is extremely useful if your original process created child processes (possibly zombie when you query) which prefix the original process' name in their own name and you are trying to exclude them from your results. There are many UNIX daemons which do this. My go-to example is ninja-dev-sync.

It took me a bit of scouting around to suss this out, but I've settled on this cross-browser implementation:

HTML

<div class="video" style="display: none">
    <div class="mask"></div>
    <a href="#" class="close-btn"><span class="fa fa-times"></span></a>
    <div class="overlay">
        <iframe id="player" width="100%" height="70%" src="//www.youtube.com/embed/Xp697DqsbUU" frameborder="0" allowfullscreen></iframe>
    </div>
</div>

jQuery

$('.launch-video').click(function() {
  $('.video').show();
  $("#player").attr('src','//www.youtube.com/embed/Xp697DqsbUU'); 
});

$('.close-btn').click(function() {
  $('.video').hide();
  $("#player").attr('src','');   
});

What it essentially does is open my lightbox and populate my src attribute, and on close, just remove the src value (then re-populates it on open).

Another option compatible to 4.0:

Before committing the changes, you can recover the new CayenneDataObject object(s) from the collection associated to the context, like this:

CayenneDataObject dataObjectsCollection = (CayenneDataObject)cayenneContext.newObjects();

then access the ObjectId for each one in the collection, like:

ObjectId objectId = dataObject.getObjectId();

Finally you can iterate under the values, where usually the generated-id is going to be the first one of the values (for a single column key) in the Map returned by getIdSnapshot(), it contains also the column name(s) associated to the PK as key(s):

objectId.getIdSnapshot().values()

PrincipalContext pc1 = new PrincipalContext(ContextType.Domain, "DomainName", UserAccountOU, UserName, Password);
UserPrincipal UserPrincipalID = UserPrincipal.FindByIdentity(pc1, IdentityType.SamAccountName, UserID);

searcher.Filter = "(&(ObjectClass=group)(member = " + UserPrincipalID.DistinguishedName + "));

Client side Upload Canceling

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE, can be tampered with so always use server side validation.

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="Submit" />
</form>

<script>
document.forms[0].addEventListener('submit', function( evt ) {
    var file = document.getElementById('file').files[0];

    if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
        //Submit form        
    } else {
        //Prevent default and display error
        evt.preventDefault();
    }
}, false);
</script>

Server Side Upload Canceling

On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.

PHP Validation

On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES array to find out the upload size. (Docs on the contents of $_FILES can be found below the MAX_FILE_SIZE docs)

upload.php

<?php
if(isset($_FILES['file'])) {
    if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
        // File too big
    } else {
        // File within size restrictions
    }
}

for (int i = 0; i < 5; i++){
    int asciiVal = rand()%26 + 97;
    char asciiChar = asciiVal;
    cout << asciiChar << " and ";
}

git gui blame <filename>

Gives you a nice graphical display of changes like "git blame" but with clickable links per line, to move into earlier commits. Hover over the links to get a popup with commit details. Not my credits... found it here:

http://zsoltfabok.com/blog/2012/02/git-blame-line-history/

git gui is a graphical Tcl/Tc interface to git. Without any other params it starts a pretty simple but useful graphical app for committing files, hunks or even single lines and other similar commands like amend, revert, push... It's part of the git stock suite. On windows it is included in the installer. On debian - I don't know about other *nix systems - it has to be installed separately:

apt-get install git-gui

From the docs:

https://git-scm.com/docs/git-gui

DESCRIPTION

A Tcl/Tk based graphical user interface to Git. git gui focuses on allowing users to make changes to their repository by making new commits, amending existing ones, creating branches, performing local merges, and fetching/pushing to remote repositories.

Unlike gitk, git gui focuses on commit generation and single file annotation and does not show project history. It does however supply menu actions to start a gitk session from within git gui.

git gui is known to work on all popular UNIX systems, Mac OS X, and Windows (under both Cygwin and MSYS). To the extent possible OS specific user interface guidelines are followed, making git gui a fairly native interface for users.

COMMANDS

blame

Start a blame viewer on the specified file on the given version (or working directory if not specified).

browser

Start a tree browser showing all files in the specified commit. Files selected through the browser are opened in the blame viewer.

citool

Start git gui and arrange to make exactly one commit before exiting and returning to the shell. The interface is limited to only commit actions, slightly reducing the application’s startup time and simplifying the menubar.

version

Display the currently running version of git gui.

The file google-services.json should be pasted in the app/ directory. After this is when I sync the project with gradle file the unexpected Top level exception error comes. This is occurring because:

Project-Level Gradle File having

dependencies {
    classpath 'com.android.tools.build:gradle:1.0.0'
    classpath 'com.google.gms:google-services:1.3.0-beta1'
}

and App-Level Gradle File having:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:7.5.0' // commenting this lineworks for me
}

The top line is creating a conflict between this and classpath 'com.google.gms:google-services:1.3.0-beta1' So I make comment it now it works Fine and no error of File google-services.json is missing from module root folder. The Google Quickstart Plugin cannot function without it.

Once I got 499 "Request has been forbidden by antivirus" as an AJAX http response (false positive by Kaspersky Internet Security with light heuristic analysis, deep heuristic analysis knew correctly there was nothing wrong).

Are those tags on 'http://www.mywebaddress.com'?

Bear in mind the linter will follow the og:url tag as this tag should point to the canonical URL of the piece of content - so if you have a page, e.g. 'http://mywebaddress.com/article1' with an og:url tag pointing to 'http://mywebaddress.com', Facebook will go there and read the tags there also.

Failing that, the most common reason i've seen for seemingly correct tags not being detected by the linter is user-agent detection returning different content to Facebook's crawler than the content you're seeing when you manually check

Bit of a long shot, but on a lab a while back, we had a situation where a SQL Server appeared unresponsive, not because we had spiked the CPU or anything we could track within SQL Server, it appeared operational to all tests but connections failed under some load.

The issue turned out to be due to the volume of traffic against the server meant we were triggering the in built windows Syn Attack Flood Protection within Windows. Annoyingly when you hit this, there is no logged message within windows server, or within SQL - you only see the symtpoms which are connections failing to be made - this is because windows slows down on accepting the messages and let's a queue build. From the connection standpoint, the server appears to not respond when it should (it doesn't even acknowledge the message arrived)

http://msdn.microsoft.com/en-us/library/ee377084(v=bts.10).aspx

Scroll down to SynAttackProtect and you will see the default in windows server 2003 sp1 onwards was to enable this feature by default. It is a DDOS protection mechanism in effect, and the lack of logging that it is triggering makes it incredibly difficult to detect when your server does this.

It took 3 days within the MS lab before it was figured out.

You mentioned 100 conenctions, we had an app that constantly connected, ran queries and then disconnected, it did not hold the connections open. This meant that we had multiple threads on each machine connectiong doing this, 10 machines, multiple threads per machine, and it was considered enough different connections consistently being made / dropped to trigger the defense.

Whether you are at that level (since it is not a clearly defined threshold by MS) is hard to say.

I move the whole directory from my Windows installation to a unix production server and I got the same error. To fix it, I just ran these two lines in unix and everything started to run fine

A bit optimized(for me atleast) solution. write this to a file db.js and require this to wherever required and call it with a function call and you are good to go.

   const MongoClient = require('mongodb').MongoClient;
    async function getConnections(url,db){
        return new Promise((resolve,reject)=>{
            MongoClient.connect(url, { useUnifiedTopology: true },function(err, client) {
                if(err) { console.error(err) 
                    resolve(false);
                }
                else{
                    resolve(client.db(db));
                }
            })
        });
    }

    module.exports = async function(){
        let dbs      = [];
        dbs['db1']     = await getConnections('mongodb://localhost:27017/','db1');
        dbs['db2']     = await getConnections('mongodb://localhost:27017/','db2');
        return dbs;
    };

I had the same exact issue on my ArchLinux VPS today.

mysql -u root -p just didn't work, whereas mysql -u root -pmypassword did.

It turned out I had a broken /dev/tty device file (most likely after a udev upgrade), so mysql couldn't use it for an interactive login.

I ended up removing /dev/tty and recreating it with mknod /dev/tty c 5 1 and chmod 666 /dev/tty. That solved the mysql problem and some other issues too.

For exporting the instances of the classes you can use this syntax:

// export index.js
const Foo = require('./my/module/foo');
const Bar = require('./my/module/bar');

module.exports = {
    Foo : new Foo(),
    Bar : new Bar()
};

// import and run method
const {Foo,Bar} = require('module_name');
Foo.test();

If double quotes does not work , try including the string within square brackets.

For eg:

SELECT "Business Name","Other Name" FROM your_Table

can be changed as

SELECT [Business Name],[Other Name] FROM your_Table

It is possible you use the bash program, with the parameter -c for execute the commands:

bashCommand = "cwm --rdf test.rdf --ntriples > test.nt"
output = subprocess.check_output(['bash','-c', bashCommand])

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

If none of them are working then check this.. say if you have x and y arrays of data along respective axis. Then check in which cell(jupyter) you have initialized x and y to empty. This is because , maybe you are appending data to x and y without re-initializing them. So plot has old data too. So check that..

The marketing release number is for the customers, called version number. It starts with 1.0 and goes up for major updates to 2.0, 3.0, for minor updates to 1.1, 1.2 and for bug fixes to 1.0.1, 1.0.2 . This number is oriented about releases and new features.

The build number is mostly the internal number of builds that have been made until then. But some use other numbers like the branch number of the repository. This number should be unique to distinguish the different nearly the same builds.

As you can see, the build number is not necessary and it is up to you which build number you want to use. So if you update your Xcode to a major version, the build field is empty. The version field may not be empty!.

To get the build number as a NSString variable:

NSString * appBuildString = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

To get the version number as a NSString variable:

NSString * appVersionString = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

If you want both in one NSString:

NSString * versionBuildString = [NSString stringWithFormat:@"Version: %@ (%@)", appVersionString, appBuildString];

This is tested with Xcode Version 4.6.3 (4H1503). The build number is often written in parenthesis / braces. The build number is in hexadecimal or decimal.

In Xcode you can auto-increment the build number as a decimal number by placing the following in the Run script build phase in the project settings

#!/bin/bash    
buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

For hexadecimal build number use this script

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$((0x$buildNumber)) 
buildNumber=$(($buildNumber + 1)) 
buildNumber=$(printf "%X" $buildNumber)
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

At the most basic level, something of the form (function(){...})() is a function literal that is executed immediately. What this means is that you have defined a function and you are calling it immediately.

This form is useful for information hiding and encapsulation since anything you define inside that function remains local to that function and inaccessible from the outside world (unless you specifically expose it - usually via a returned object literal).

A variation of this basic form is what you see in jQuery plugins (or in this module pattern in general). Hence:

(function($) {
  ...
})(jQuery);

Which means you're passing in a reference to the actual jQuery object, but it's known as $ within the scope of the function literal.

Type 1 isn't really a plugin. You're simply assigning an object literal to jQuery.fn. Typically you assign a function to jQuery.fn as plugins are usually just functions.

Type 2 is similar to Type 1; you aren't really creating a plugin here. You're simply adding an object literal to jQuery.fn.

Type 3 is a plugin, but it's not the best or easiest way to create one.

To understand more about this, take a look at this similar question and answer. Also, this page goes into some detail about authoring plugins.

I know my case is rare, but I'll still add it here for someone who troubleshoots it later. I had a Linux Kernel module target in my Makefile and I tried to compile my user space program together with the kernel module that doesn't have stdio. Making it a separate target solved the problem.

Not in stock Windows but it is provided by Services for Unix and there are several simple batch scripts floating around that accomplish the same thing such this this one.

Posed question

Responding to the question 'what metric should be used for multi-class classification with imbalanced data': Macro-F1-measure. Macro Precision and Macro Recall can be also used, but they are not so easily interpretable as for binary classificaion, they are already incorporated into F-measure, and excess metrics complicate methods comparison, parameters tuning, and so on.

Micro averaging are sensitive to class imbalance: if your method, for example, works good for the most common labels and totally messes others, micro-averaged metrics show good results.

Weighting averaging isn't well suited for imbalanced data, because it weights by counts of labels. Moreover, it is too hardly interpretable and unpopular: for instance, there is no mention of such an averaging in the following very detailed survey I strongly recommend to look through:

Sokolova, Marina, and Guy Lapalme. "A systematic analysis of performance measures for classification tasks." Information Processing & Management 45.4 (2009): 427-437.

Application-specific question

However, returning to your task, I'd research 2 topics:

1. metrics commonly used for your specific task - it lets (a) to compare your method with others and understand if you do something wrong, and (b) to not explore this by yourself and reuse someone else's findings;
2. cost of different errors of your methods - for example, use-case of your application may rely on 4- and 5-star reviewes only - in this case, good metric should count only these 2 labels.

Commonly used metrics. As I can infer after looking through literature, there are 2 main evaluation metrics:

1. Accuracy, which is used, e.g. in

Yu, April, and Daryl Chang. "Multiclass Sentiment Prediction using Yelp Business."

(link) - note that the authors work with almost the same distribution of ratings, see Figure 5.

Pang, Bo, and Lillian Lee. "Seeing stars: Exploiting class relationships for sentiment categorization with respect to rating scales." Proceedings of the 43rd Annual Meeting on Association for Computational Linguistics. Association for Computational Linguistics, 2005.

(link)

2. MSE (or, less often, Mean Absolute Error - MAE) - see, for example,

Lee, Moontae, and R. Grafe. "Multiclass sentiment analysis with restaurant reviews." Final Projects from CS N 224 (2010).

(link) - they explore both accuracy and MSE, considering the latter to be better

Pappas, Nikolaos, Rue Marconi, and Andrei Popescu-Belis. "Explaining the Stars: Weighted Multiple-Instance Learning for Aspect-Based Sentiment Analysis." Proceedings of the 2014 Conference on Empirical Methods In Natural Language Processing. No. EPFL-CONF-200899. 2014.

(link) - they utilize scikit-learn for evaluation and baseline approaches and state that their code is available; however, I can't find it, so if you need it, write a letter to the authors, the work is pretty new and seems to be written in Python.

Cost of different errors. If you care more about avoiding gross blunders, e.g. assinging 1-star to 5-star review or something like that, look at MSE; if difference matters, but not so much, try MAE, since it doesn't square diff; otherwise stay with Accuracy.

About approaches, not metrics

Try regression approaches, e.g. SVR, since they generally outperforms Multiclass classifiers like SVC or OVA SVM.

By calling method

public class a 
{
    void sum(int i,int k)
    {
        System.out.println("THe sum of the number="+(i+k));
    }
}
class b
{
    public static void main(String[] args)
    {
        a vc=new a();
        vc.sum(10 , 20);
    }
}

git log -1 --stat

could work

Search for   or only nbsp - did you try this?

You must convert to List as shown below:

    String[] valores = hierarquia.split(".");       
    List<String> lista =  Arrays.asList(valores);

    String jpqlQuery = "SELECT a " +
            "FROM AcessoScr a " +
            "WHERE a.scr IN :param ";

    Query query = getEntityManager().createQuery(jpqlQuery, AcessoScr.class);                   
    query.setParameter("param", lista);     
    List<AcessoScr> acessos = query.getResultList();

It will hopefully be available soon in Javascript, as it is in proposal phase as of Apr, 2020. You can monitor the status here for compatibility and support - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Nullish_coalescing_operator

For people using Typescript, you can use the nullish coalescing operator from Typescript 3.7

From the docs -

You can think of this feature - the ?? operator - as a way to “fall back” to a default value when dealing with null or undefined. When we write code like

let x = foo ?? bar();

this is a new way to say that the value foo will be used when it’s “present”; but when it’s null or undefined, calculate bar() in its place.

Since Java 7 you can do the same with Files.newBufferedWriter a little more succinctly:

Path logFile = Paths.get("/tmp/example.txt");
try (BufferedWriter writer = Files.newBufferedWriter(logFile, StandardCharsets.UTF_8)) {
    writer.write("Hello World!");
    // ...
}

You can use forwarding to remove the previous activity from the activity stack while launching the next one. There's an example of this in the APIDemos, but basically all you're doing is calling finish() immediately after calling startActivity().

not Error:

JSONObject json1 = getJsonX();

Error:

JSONObject json2 = null;
if(x == y)
   json2 = getJSONX();

Error: Local variable statement defined in an enclosing scope must be final or effectively final.

But you can write:

JSONObject json2 = (x == y) ? json2 = getJSONX() : null;

Check if in your php.ini file has the following line:

;extension=php_gd2.dll

if exists, change it to

extension=php_gd2.dll

and restart apache

(it works on MAC)

It can be convenient to approach argument detection by evoking your function with an Object of optional properties:

function foo(options) {
    var config = { // defaults
        list: 'string value',
        of: [a, b, c],
        optional: {x: y},
        objects: function(param){
           // do stuff here
        }
    }; 
    if(options !== undefined){
        for (i in config) {
            if (config.hasOwnProperty(i)){
                if (options[i] !== undefined) { config[i] = options[i]; }
            }
        }
    }
}

Hope this helps:

First, your success() handler just returns the data, but that's not returned to the caller of getData() since it's already in a callback. $http is an asynchronous call that returns a $promise, so you have to register a callback for when the data is available.

I'd recommend looking up Promises and the $q library in AngularJS since they're the best way to pass around asynchronous calls between services.

For simplicity, here's your same code re-written with a function callback provided by the calling controller:

var myApp = angular.module('myApp',[]);

myApp.service('dataService', function($http) {
    delete $http.defaults.headers.common['X-Requested-With'];
    this.getData = function(callbackFunc) {
        $http({
            method: 'GET',
            url: 'https://www.example.com/api/v1/page',
            params: 'limit=10, sort_by=created:desc',
            headers: {'Authorization': 'Token token=xxxxYYYYZzzz'}
        }).success(function(data){
            // With the data succesfully returned, call our callback
            callbackFunc(data);
        }).error(function(){
            alert("error");
        });
     }
});

myApp.controller('AngularJSCtrl', function($scope, dataService) {
    $scope.data = null;
    dataService.getData(function(dataResponse) {
        $scope.data = dataResponse;
    });
});

Now, $http actually already returns a $promise, so this can be re-written:

var myApp = angular.module('myApp',[]);

myApp.service('dataService', function($http) {
    delete $http.defaults.headers.common['X-Requested-With'];
    this.getData = function() {
        // $http() returns a $promise that we can add handlers with .then()
        return $http({
            method: 'GET',
            url: 'https://www.example.com/api/v1/page',
            params: 'limit=10, sort_by=created:desc',
            headers: {'Authorization': 'Token token=xxxxYYYYZzzz'}
         });
     }
});

myApp.controller('AngularJSCtrl', function($scope, dataService) {
    $scope.data = null;
    dataService.getData().then(function(dataResponse) {
        $scope.data = dataResponse;
    });
});

Finally, there's better ways to configure the $http service to handle the headers for you using config() to setup the $httpProvider. Checkout the $http documentation for examples.

You can get the key using values using following code..

ArrayList valuesList = new ArrayList();
Set keySet = initalMap.keySet();
ArrayList keyList = new ArrayList(keySet);

for(int i = 0 ; i < keyList.size() ; i++ ) {
    valuesList.add(initalMap.get(keyList.get(i)));
}

Collections.sort(valuesList);
Map finalMap = new TreeMap();
for(int i = 0 ; i < valuesList.size() ; i++ ) {
    String value = (String) valuesList.get(i);

    for( int j = 0 ; j < keyList.size() ; j++ ) {
        if(initalMap.get(keyList.get(j)).equals(value)) {
            finalMap.put(keyList.get(j),value);
        }   
    }
}
System.out.println("fianl map ---------------------->  " + finalMap);

Well, the shortest way I know of, is following:

psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}

database_name: Which database should you insert your file data in.

file_path: Absolute path to the file through which you want to perform the importing.

host_name: The name of the host. For development purposes, it is mostly localhost.

Upon entering this command in console, you will be prompted to enter your password.

Use let instead of var in code :

for(let i=1;i<=5;i++){setTimeout(()=>{console.log(i)},1000);}

If someone has the same issue as I had - make sure that you don't install from the Ubuntu 14.04 repo onto a 12.04 machine - it gives this same error. Reinstalling from the proper repository fixed the issue.

DECLARE @chr nvarchar(50) = (SELECT CONVERT(nvarchar(50), GETDATE(), 103))

SELECT @chr chars, CONVERT(date, @chr, 103) date_again

Just another possibility: Spring initializes bean by type not by name if you don't define bean with a name, which is ok if you use it by its type:

Producer:

@Service
public void FooServiceImpl implements FooService{}

Consumer:

@Autowired
private FooService fooService;

or

@Autowired
private void setFooService(FooService fooService) {}

but not ok if you use it by name:

ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
ctx.getBean("fooService");

It would complain: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'fooService' is defined In this case, assigning name to @Service("fooService") would make it work.

In app.config file (or .exe.config) you can add or change the "receiveTimeout" property in binding. like this

<binding name="WebServiceName" receiveTimeout="00:00:59" />

It is SUBSTITUTE(B1," ",""), not REPLACE(xx;xx;xx).

/\(?([0-9]{3})\)?([ .-]?)([0-9]{3})\2([0-9]{4})/

Supports :

• (123) 456 7899
• (123).456.7899
• (123)-456-7899
• 123-456-7899

Now it is possible to set click_action in Firebase Console. You just go to notifications-send message-advanced option and there you will have two fields for key and value. In first field you put click_action and in second you put some text which represents value of that action. And you add intent-filter in your Manifest and give him the same value as you wrote in console. And that is simulation of real click_action.

The basic questions that differentiate implementations of "CopyStream" are:

• size of the reading buffer
• size of the writes
• Can we use more than one thread (writing while we are reading).

The answers to these questions result in vastly different implementations of CopyStream and are dependent on what kind of streams you have and what you are trying to optimize. The "best" implementation would even need to know what specific hardware the streams were reading and writing to.

I do this:

git rm --cached `git ls-files -i --exclude-from=.gitignore` 
git commit -m 'Removed all files that are in the .gitignore' 
git push origin master

Which will remove all the files/folders that are in your git ignore, saving you have to pick each one manually

This seems to have stopped working for me, I now do:

 git rm -r --cached . 
 git add .
 git commit -m 'Removed all files that are in the .gitignore' 
 git push origin master

The documentation for Gerrit, in particular the "Push changes" section, explains that you push to the "magical refs/for/'branch' ref using any Git client tool".

The following image is taken from the Intro to Gerrit. When you push to Gerrit, you do git push gerrit HEAD:refs/for/<BRANCH>. This pushes your changes to the staging area (in the diagram, "Pending Changes"). Gerrit doesn't actually have a branch called <BRANCH>; it lies to the git client.

Internally, Gerrit has its own implementation for the Git and SSH stacks. This allows it to provide the "magical" refs/for/<BRANCH> refs.

When a push request is received to create a ref in one of these namespaces Gerrit performs its own logic to update the database, and then lies to the client about the result of the operation. A successful result causes the client to believe that Gerrit has created the ref, but in reality Gerrit hasn’t created the ref at all. [Link - Gerrit, "Gritty Details"].

After a successful patch (i.e, the patch has been pushed to Gerrit, [putting it into the "Pending Changes" staging area], reviewed, and the review has passed), Gerrit pushes the change from the "Pending Changes" into the "Authoritative Repository", calculating which branch to push it into based on the magic it did when you pushed to refs/for/<BRANCH>. This way, successfully reviewed patches can be pulled directly from the correct branches of the Authoritative Repository.

If for matching identical images ( same size/orientation )

// Compare two images by getting the L2 error (square-root of sum of squared error).
double getSimilarity( const Mat A, const Mat B ) {
if ( A.rows > 0 && A.rows == B.rows && A.cols > 0 && A.cols == B.cols ) {
    // Calculate the L2 relative error between images.
    double errorL2 = norm( A, B, CV_L2 );
    // Convert to a reasonable scale, since L2 error is summed across all pixels of the image.
    double similarity = errorL2 / (double)( A.rows * A.cols );
    return similarity;
}
else {
    //Images have a different size
    return 100000000.0;  // Return a bad value
}

You have to register the annotation binding for Jackson in your spring-mvc-config.xml, for example :

<!-- activates annotation driven binding -->
<mvc:annotation-driven ignoreDefaultModelOnRedirect="true" validator="validator">
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"/>
        <bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"/>
        <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
    </mvc:message-converters>
</mvc:annotation-driven>

Then in your controller you can use :

@RequestMapping(value = "/your_url", method = RequestMethod.GET, produces = "application/json")
@ResponseBody

All major browsers now include native JSON encoding/decoding.

// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject); 

// To decode (This produces an object)
var obj = JSON.parse(json_str);

Note that only valid JSON data will be encoded. For example:

var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"

Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.

Some JSON resources:

• JSON on Mozilla Developer Network
• JSON on Wikipedia

To keep all objects whose names match a pattern, you could use grep, like so:

to.remove <- ls()
to.remove <- c(to.remove[!grepl("^obj", to.remove)], "to.remove")
rm(list=to.remove)

This is the simplest way I found. I used your html. The padding is just to reset browser defaults.

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

Short, secure, without plugin:

:sav new_name
:!rm <C-R>#  // or !del <C-R># for windows

control + R, # will instantly expand to an alternate-file (previously edited path in current window) before pressing Enter. That allows us to review what exactly we're going to delete. Using pipe | in such a case is not secure, because if sav fails for any reason, # will still point to another place (or to nothing). That means !rm # or delete(expand(#)) may delete completely different file! So do it by hand carefully or use good script (they are mentioned in many answers here).

Educational

...or try build a function/command/script yourself. Start from sth simple like:

command! -nargs=1 Rename saveas <args> | call delete(expand('#')) | bd #

after vimrc reload, just type :Rename new_filename. What is the problem with this command?

Security test 1: What does:Rename without argument?

Yes, it deletes file hidden in '#' !

Solution: you can use eg. conditions or try statement like that:

command! -nargs=1 Rename try | saveas <args> | call delete(expand('#')) | bd # | endtry

Security test 1: :Rename (without argument) will throw an error:

E471: Argument required

Security test 2: What if the name will be the same like previous one?

Security test 3: What if the file will be in different location than your actual?

Fix it yourself. For readability you can write it in this manner:

function! s:localscript_name(name):
  try
    execute 'saveas ' . a:name
    ...
  endtry
endfunction
command! -nargs=1 Rename call s:localscript_name(<f-args>)

notes

• !rm # is better than !rm old_name -> you don't need remember the old name

• !rm <C-R># is better than !rm # when do it by hand -> you will see what you actually remove (safety reason)

• !rm is generally not very secure... mv to a trash location is better

• call delete(expand('#')) is better than shell command (OS agnostic) but longer to type and impossible to use control + R

• try | code1 | code2 | tryend -> when error occurs while code1, don't run code2

• :sav (or :saveas) is equivalent to :f new_name | w - see file_f - and preserves undo history

• expand('%:p') gives whole path of your location (%) or location of alternate file (#)

I would suggest separating your code based on the functionality and purpose specific to each sheet or module. In this manner, you would only put code relative to a sheet's UI inside the sheet's module and only put code related to modules in respective modules. Also, use separate modules to encapsulate code that is shared or reused among several different sheets.

For example, let's say you multiple sheets that are responsible for displaying data from a database in a special way. What kinds of functionality do we have in this situation? We have functionality related to each specific sheet, tasks related to getting data from the database, and tasks related to populating a sheet with data. In this case, I might start with a module for the data access, a module for populating a sheet with data, and within each sheet I'd have code for accessing code in those modules.

It might be laid out like this.

Module: DataAccess:

Function GetData(strTableName As String, strCondition1 As String) As Recordset
    'Code Related to getting data from the database'
End Function

Module: PopulateSheet:

Sub PopulateASheet(wsSheet As Worksheet, rs As Recordset)
    'Code to populate a worksheet '
End Function

Sheet: Sheet1 Code:

Sub GetDataAndPopulate()
    'Sample Code'
     Dim rs As New Recordset
     Dim ws As Worksheet
     Dim strParam As String
     Set ws = ActiveSheet
     strParam = ws.Range("A1").Value

     Set rs = GetData("Orders",strParam)

     PopulateASheet ws, rs
End Sub

Sub Button1_Click()
    Call GetDataAndPopulate
End Sub

Since your local repository is few commits ahead, git tries to merge your remote to your local repo. This can be handled via merge, but in your case, perhaps you are looking for rebase, i.e. add your commit to the top. You can do this with

git rebase or git pull --rebase

Here is a good article explaining the difference between git pull & git pull --rebase.

https://www.derekgourlay.com/blog/git-when-to-merge-vs-when-to-rebase/

You can add a PPA that provides a relatively current version of SmartGit(as well as SmartGitHg, the predecessor of SmartGit).

To add the PPA run:

sudo add-apt-repository ppa:eugenesan/ppa
sudo apt-get update

To install smartgit (after adding the PPA) run:

sudo apt-get install smartgit

To install smartgithg (after adding the PPA) run:

sudo apt-get install smartgithg

This should add a menu option for you

You can also look into pandas.Timestamp, which includes methods like .now and .today. Unlike pandas.to_datetime('now'), pandas.Timestamp.now() won't default to UTC:

we do check the IsDisposed property on the schedule component before using it in the Timer Tick event but it doesn't help.

If I understand that stack trace, it's not your timer which is the problem, it's one in the control itself - it might be them who are not cleaning-up properly.

Are you explicitly calling Dispose on their control?

Give permission in .htaccess as follows:

<Directory "Your directory path/uploads/">
Allow from all
</Directory>

You can try with Directory.GetFiles and fix your pattern

 string[] files = Directory.GetFiles(@"c:\", "*.txt");

 foreach (string file in files)
 {
    File.Copy(file, "....");
 }

 Or Move

 foreach (string file in files)
 {
    File.Move(file, "....");
 }

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

If you want to check for local files first do:

@font-face {
font-family: 'Green Sans Web';
src:
    local('Green Web'),
    local('GreenWeb-Regular'),
    url('GreenWeb.ttf');
}

There is a more elaborate description of what to do here.

This works and it is a lot easier to toggle that the methods above:

use inline: onended="if($(this).attr('data-loop')){ this.currentTime = 0; this.play(); }"

Turn the looping on by $(audio_element).attr('data-loop','1'); Turn the looping off by $(audio_element).removeAttr('data-loop');

Both answers are in the ballpark but neither is a complete answer.

MyClass.class.isInstance(obj) is for checking an instance. It returns true when the parameter obj is non-null and can be cast to MyClass without raising a ClassCastException. In other words, obj is an instance of MyClass or its subclasses.

MyClass.class.isAssignableFrom(Other.class) will return true if MyClass is the same as, or a superclass or superinterface of, Other. Other can be a class or an interface. It answers true if Other can be converted to a MyClass.

A little code to demonstrate:

public class NewMain
{
    public static void main(String[] args)
    {
        NewMain nm = new NewMain();
        nm.doit();
    }

    class A { }

    class B extends A { }

    public void doit()
    {
        A myA = new A();
        B myB = new B();
        A[] aArr = new A[0];
        B[] bArr = new B[0];

        System.out.println("b instanceof a: " + (myB instanceof A)); // true
        System.out.println("b isInstance a: " + A.class.isInstance(myB)); //true
        System.out.println("a isInstance b: " + B.class.isInstance(myA)); //false
        System.out.println("b isAssignableFrom a: " + A.class.isAssignableFrom(B.class)); //true
        System.out.println("a isAssignableFrom b: " + B.class.isAssignableFrom(A.class)); //false
        System.out.println("bArr isInstance A: " + A.class.isInstance(bArr)); //false
        System.out.println("bArr isInstance aArr: " + aArr.getClass().isInstance(bArr)); //true
        System.out.println("bArr isAssignableFrom aArr: " + aArr.getClass().isAssignableFrom(bArr.getClass())); //true
    }
}

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

You can do it by using pymysql:

For example, let's suppose you have a MySQL database with the next user, password, host and port and you want to write in the database 'data_2', if it is already there or not.

import pymysql
user = 'root'
passw = 'my-secret-pw-for-mysql-12ud'
host =  '172.17.0.2'
port = 3306
database = 'data_2'

If you already have the database created:

conn = pymysql.connect(host=host,
                       port=port,
                       user=user, 
                       passwd=passw,  
                       db=database,
                       charset='utf8')

data.to_sql(name=database, con=conn, if_exists = 'replace', index=False, flavor = 'mysql')

If you do NOT have the database created, also valid when the database is already there:

conn = pymysql.connect(host=host, port=port, user=user, passwd=passw)

conn.cursor().execute("CREATE DATABASE IF NOT EXISTS {0} ".format(database))
conn = pymysql.connect(host=host,
                       port=port,
                       user=user, 
                       passwd=passw,  
                       db=database,
                       charset='utf8')

data.to_sql(name=database, con=conn, if_exists = 'replace', index=False, flavor = 'mysql')

I was also facing a similar issue ("no runnable methods..") on running the simplest of simple piece of code (Using @Test, @Before etc.) and found the solution nowhere. I was using Junit4 and Eclipse SDK version 4.1.2. Resolved my problem by using the latest Eclipse SDK 4.2.2. I hope this helps people who are struggling with a somewhat similar issue.

If you want to call them like that, you should declare them static.

For posterity, I think this is quicker:

a = np.array([np.array(list()) for _ in y])

You might even be able to pass in a generator (i.e. [] -> ()), in which case the inner list is never fully stored in memory.

Responding to comment below:

>>> import numpy as np
>>> y = range(10)
>>> a = np.array([np.array(list) for _ in y])
>>> a
array([array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),

       array(<type 'list'>, dtype=object)], dtype=object)

It's the "null coalescing operator", added in php 7.0. The definition of how it works is:

It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

So it's actually just isset() in a handy operator.

Those two are equivalent¹:

$foo = $bar ?? 'something';
$foo = isset($bar) ? $bar : 'something';

¹There is a difference: In case of ??, the first expression is evaluated only once, as opposed to ? :, where the expression is first evaluated in the condition section, then the second time in the "answer" section.

This works,

#!/usr/bin/Rscript

but I don't know what happens if you have more than 1 version of R installed on your machine.

If you do it like this

#!/usr/bin/env Rscript

it tells the interpreter to just use whatever R appears first on your path.

In Windows Forms and WPF:

textbox.SelectionStart = 0;

WHERE customers.customer_name = suppliers.supplier_name)

datepicker doesnot have a maxDate as an option.I used this endDate option.It worked well.

>                 endDate: new Date()
>             });

I don't know, it works fine for me. Exact commands:

import scipy, pylab
ax = pylab.subplot(111)
ax.scatter(scipy.randn(100), scipy.randn(100), c='b')
ax.scatter(scipy.randn(100), scipy.randn(100), c='r')
ax.figure.show()

You could store the data in an array of strings of some large fixed size. It should be efficient to access any particular character in that array of strings, and to treat that character as a byte.

It would be interesting to see the operations you want to support, perhaps expressed as an interface, to make the question more concrete.

Try to think in terms of a model and what happens to that model when a checkbox is checked.

Assuming that each checkbox is bound to a field on the model with ng-model then the property on the model is changed whenever a checkbox is clicked:

<input type='checkbox' ng-model='fooSelected' />
<input type='checkbox' ng-model='baaSelected' />

and in the controller:

$scope.fooSelected = false;
$scope.baaSelected = false;

The next button should only be available under certain circumstances so add the ng-disabled directive to the button:

<button type='button' ng-disabled='nextButtonDisabled'></button>

Now the next button should only be available when either fooSelected is true or baaSelected is true and we need to watch any changes to these fields to make sure that the next button is made available or not:

$scope.$watch('[fooSelected,baaSelected]', function(){
    $scope.nextButtonDisabled = !$scope.fooSelected && !scope.baaSelected;
}, true );

The above assumes that there are only a few checkboxes that affect the availability of the next button but it could be easily changed to work with a larger number of checkboxes and use $watchCollection to check for changes.

Two ways that work:

1. Use stringBuilderObj.setLength(0).
2. Allocate a new one with new StringBuilder() instead of clearing the buffer.

There's a much better solution for this problem.

Just take a normal Button and use the drawableLeft and the gravity attributes.

<Button
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:drawableLeft="@drawable/my_btn_icon"
  android:gravity="left|center_vertical" />

This way you get a button which displays a icon in the left side of the button and the text at the right site of the icon vertical centered.

I found some elegant solution on MSDN

System.Console.Write('\uXXXX') //XXXX is hex Unicode for character

This simple program writes ? right on the screen.

        Console.Write('\u2103'); //? character code
    }
}

Those are by no means the same. The first will simply send you to whatever URL you have assigned to window.location.href (in the same window you're currently in). The second makes a GET AJAX request.

Try this page: http://www.codebelt.com/jquery/open-new-browser-window-with-jquery-custom-size/

It gives a great example on how to open a new window*.

If you wish to use raw javascript then this is what you're looking for:

window.open(URL,name,specs,replace)

As seen in http://www.w3schools.com/jsref/met_win_open.asp

Use its value directly:

In [79]: df[df.c > 0.5][['b', 'e']].values
Out[79]: 
array([[ 0.98836259,  0.82403141],
       [ 0.337358  ,  0.02054435],
       [ 0.29271728,  0.37813099],
       [ 0.70033513,  0.69919695]])

Or with standard Java API you can use java.util.Properties:

Properties props = new Properties();
try (FileInputStream in = new FileInputStream(path)) {
    props.load(in);
}

I know this is old, but most of these answers require a ton of extra code.

If you have a light colored background, you can simply use this:

I have not been able to find a Firefox option equivalent of --disable-web-security or an addon that does that for me. I really needed it for some testing scenarios where modifying the web server was not possible. What did help was to use Fiddler to auto-modify web responses so that they have the correct headers and CORS is no longer an issue.

The steps are:

1. Open fiddler.

2. If on https go to menu Tools -> Options -> Https and tick the Capture & Decrypt https options

3. Go to menu Rules -> Customize rules. Modify the OnBeforeResponseFunction so that it looks like the following, then save:

    static function OnBeforeResponse(oSession: Session) {
       //....
       oSession.oResponse.headers.Remove("Access-Control-Allow-Origin");
       oSession.oResponse.headers.Add("Access-Control-Allow-Origin", "*");
       //...
    }
   

   This will make every web response to have the Access-Control-Allow-Origin: * header.

4. This still won't work as the OPTIONS preflight will pass through and cause the request to block before our above rule gets the chance to modify the headers. So to fix this, in the fiddler main window, on the right hand side there's an AutoResponder tab. Add a new rule and response: METHOD:OPTIONS https://yoursite.com/ with auto response: *CORSPreflightAllow and tick the boxes: "Enable Rules" and "Unmatched requests passthrough".

As Mingyu pointed out, there is a problem in formatting. Other than that, I would strongly recommend not using the Derived class's name while calling super() since it makes your code inflexible (code maintenance and inheritance issues). In Python 3, Use super().__init__ instead. Here is the code after incorporating these changes :

class Car(object):
    condition = "new"

    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg

class ElectricCar(Car):

    def __init__(self, battery_type, model, color, mpg):
        self.battery_type=battery_type
        super().__init__(model, color, mpg)

Thanks to Erwin Mayer for pointing out the issue in using __class__ with super()

Depending on what is needed, scikit-image may be the best choice, with manipulations going way beyond PIL and the current version of Pillow. Very well-maintained, at least as much as Pillow. Also, the underlying data structures are from Numpy and Scipy, which makes its code incredibly interoperable. Examples that pillow can't handle:

You can see its power in the gallery. This paper provides a great intro to it. Good luck!

this $('#checkboxId').is(':checked') for verify if is checked

Basically, fs.readFileSync throws an error when a file is not found. This error is from the Error prototype and thrown using throw, hence the only way to catch is with a try / catch block:

var fileContents;
try {
  fileContents = fs.readFileSync('foo.bar');
} catch (err) {
  // Here you get the error when the file was not found,
  // but you also get any other error
}

Unfortunately you can not detect which error has been thrown just by looking at its prototype chain:

if (err instanceof Error)

is the best you can do, and this will be true for most (if not all) errors. Hence I'd suggest you go with the code property and check its value:

if (err.code === 'ENOENT') {
  console.log('File not found!');
} else {
  throw err;
}

This way, you deal only with this specific error and re-throw all other errors.

Alternatively, you can also access the error's message property to verify the detailed error message, which in this case is:

ENOENT, no such file or directory 'foo.bar'

Hope this helps.

I solved the problem by enabling the mod_autoindex from Apache. It was disabled by default.

Using sed can also be elegant in this situation. Example (replace line with matched group "yyy" from line):

$ cat testfile
xxx yyy zzz
yyy xxx zzz
$ cat testfile | sed -r 's#^.*(yyy).*$#\1#g'
yyy
yyy

You can fill it from XAML or from .cs. There are few ways to fill controls with data. It would be best for You to read more about WPF technology, it allows to do many things in many ways, depending on Your needs. It's more important to choose method based on Your project needs. You can start here. It's an easy article about creating combobox, and filling it with some data.

Finally, Google realized the severity of this problem (applying custom font to UI components) and they devised a clean solution for it.

First, you need to update to support library 26+ (you may also need to update your gradle{4.0+}, android studio), then you can create a new resource folder called font. In this folder, you can put your font resources (.tff,...). Then you need to override the default app them and force your custom font into it :)

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:fontFamily">@font/my_custom_font</item>
</style>

Note: if you want to support devices with older API than 16, you have to use app namespace instead of android!

GO isn't a keyword in SQL Server; it's a batch separator. GO ends a batch of statements. This is especially useful when you are using something like SQLCMD. Imagine you are entering in SQL statements on the command line. You don't necessarily want the thing to execute every time you end a statement, so SQL Server does nothing until you enter "GO".

Likewise, before your batch starts, you often need to have some objects visible. For example, let's say you are creating a database and then querying it. You can't write:

CREATE DATABASE foo;
USE foo;
CREATE TABLE bar;

because foo does not exist for the batch which does the CREATE TABLE. You'd need to do this:

CREATE DATABASE foo;
GO
USE foo;
CREATE TABLE bar;

If you don't want to deal with security and want to make it as exposed (aka "convenient") as possible for short term, and|or don't have ssh/telnet or key generation on all your hosts, you can can hack a one-liner together with netcat. Write a command to your target computer's port over the network and it will run it. Then you can block access to that port to a few "trusted" users or wrap it in a script that only allows certain commands to run. And use a low privilege user.

on the server

mkfifo /tmp/netfifo; nc -lk 4201 0</tmp/netfifo | bash -e &>/tmp/netfifo

This one liner reads whatever string you send into that port and pipes it into bash to be executed. stderr & stdout are dumped back into netfifo and sent back to the connecting host via nc.

on the client

To run a command remotely: echo "ls" | nc HOST 4201

or

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

To elaborate on @serine's answer and illustrate working with non-trivial multi-valued condition: I had a need to show a "dim-out" overlay on an item for the boolean condition NOT a AND (b OR NOT c).

For background, this is a "Multiple Choice" question. If the user picks a wrong answer it becomes disabled (dimmed out and cannot be selected again). An automated agent has the ability to focus on any particular choice to give an explanation (border highlighted). When the agent focuses on an item, it should not be dimmed out even if it is disabled. All items that are not in focused are marked de-focused, and should be dimmed out.

The logic for dimming is thus:

NOT IsFocused AND (IsDefocused OR NOT Enabled)

To implement this logic, I made a generic IMultiValueConverter named (awkwardly) to match my logic

// 'P' represents a parenthesis
//     !  a &&  ( b ||  !  c )
class NOT_a_AND_P_b_OR_NOT_c_P : IMultiValueConverter
{
    // redacted [...] for brevity
    public object Convert(object[] values, ...)
    {
        bool a = System.Convert.ToBoolean(values[0]);
        bool b = System.Convert.ToBoolean(values[1]);
        bool c = System.Convert.ToBoolean(values[2]);

        return !a && (b || !c);
    }
    ...
}

In the XAML I use this in a MultiDataTrigger in a <Style><Style.Triggers> resource

<MultiDataTrigger>
    <MultiDataTrigger.Conditions>
        <!-- when the equation is TRUE ... -->
        <Condition Value="True">
            <Condition.Binding>
                <MultiBinding Converter="{StaticResource NOT_a_AND_P_b_OR_NOT_c_P}">
                    <!-- NOT IsFocus AND ( IsDefocused OR NOT Enabled ) -->
                    <Binding Path="IsFocus"/>
                    <Binding Path="IsDefocused" />
                    <Binding Path="Enabled" />
                </MultiBinding>
            </Condition.Binding>
        </Condition>
    </MultiDataTrigger.Conditions>
    <MultiDataTrigger.Setters>
        <!-- ... show the 'dim-out' overlay -->
        <Setter Property="Visibility" Value="Visible" />
    </MultiDataTrigger.Setters>
</MultiDataTrigger>

And for completeness sake, my converter is defined in a ResourceDictionary

<ResourceDictionary xmlns:conv="clr-namespace:My.Converters" ...>
    <conv:NOT_a_AND_P_b_OR_NOT_c_P x:Key="NOT_a_AND_P_b_OR_NOT_c_P" />
</ResourceDictionary>

In bash:

while read -r line ; do
    [[ $line == all:* ]] && line+=" anotherthing"
    echo "$line"
done < filename

Solution:

To fix it you need to fetch first

$ git fetch origin

$ git rebase origin/master

Current branch master is up to date.

$ git checkout develop

Branch develop set up to track remote branch develop from origin.

Switched to a new branch ‘develop’

vector::clear() does not free memory allocated by the vector to store objects; it calls destructors for the objects it holds.

For example, if the vector uses an array as a backing store and currently contains 10 elements, then calling clear() will call the destructor of each object in the array, but the backing array will not be deallocated, so there is still sizeof(T) * 10 bytes allocated to the vector (at least). size() will be 0, but size() returns the number of elements in the vector, not necessarily the size of the backing store.

As for your second question, anything you allocate with new you must deallocate with delete. You typically do not maintain a pointer to a vector for this reason. There is rarely (if ever) a good reason to do this and you prevent the vector from being cleaned up when it leaves scope. However, calling clear() will still act the same way regardless of how it was allocated.

//Try this if you can't use -std=c++11:-
int number=55;
char tempStr[32] = {0};
sprintf(tempStr, "%d", number);

You could also send your testers the apk that is signed with your debug key. You can find that in the bin folder of your project after building in debug mode.

You have to stop the current process and run your new one. In Eclipse, you can press this button to ReLaunch your application:

This solution helped me more, from msdn microsoft:

var result =  query.AsEnumerable().Select((x, index) =>
              new { index,x.Id,x.FirstName});

query is your toList() query.

BufferedReader#read reads single character[0 to 65535 (0x00-0xffff)] from the stream, so it is not possible to read single integer from stream.

            String s= inp.readLine();
            int[] m= new int[2];
            String[] s1 = inp.readLine().split(" ");
            m[0]=Integer.parseInt(s1[0]);
            m[1]=Integer.parseInt(s1[1]);

            // Checking whether I am taking the inputs correctly
            System.out.println(s);
            System.out.println(m[0]);
            System.out.println(m[1]);

You can check also Scanner vs. BufferedReader.

Ascii string to integer conversion is done by the atoi() function.

Not all at once. But you can press

Alt + Enter

People assume it only works when you are at the particular item. But it actually works for "next missing type". So if you keep pressing Alt + Enter, IDEA fixes one after another until all are fixed.

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

Try using inner join in your Query

    Query query=session.createQuery("from Product as p INNER JOIN p.catalog as c 
    WHERE c.idCatalog= :id and p.productName like :XXX");
    query.setParameter("id", 7);
    query.setParameter("xxx", "%"+abc+"%");
    List list = query.list();

also in the hibernate config file have

<!--hibernate.cfg.xml -->
<property name="show_sql">true</property>

To display what is being queried on the console.

By default cron logs to /var/log/syslog so you can see cron related entries by using:

grep CRON /var/log/syslog

I think a lot of times people get confused about the difference between dependency injection and a dependency injection framework (or a container as it is often called).

Dependency injection is a very simple concept. Instead of this code:

public class A {
  private B b;

  public A() {
    this.b = new B(); // A *depends on* B
  }

  public void DoSomeStuff() {
    // Do something with B here
  }
}

public static void Main(string[] args) {
  A a = new A();
  a.DoSomeStuff();
}

you write code like this:

public class A {
  private B b;

  public A(B b) { // A now takes its dependencies as arguments
    this.b = b; // look ma, no "new"!
  }

  public void DoSomeStuff() {
    // Do something with B here
  }
}

public static void Main(string[] args) {
  B b = new B(); // B is constructed here instead
  A a = new A(b);
  a.DoSomeStuff();
}

And that's it. Seriously. This gives you a ton of advantages. Two important ones are the ability to control functionality from a central place (the Main() function) instead of spreading it throughout your program, and the ability to more easily test each class in isolation (because you can pass mocks or other faked objects into its constructor instead of a real value).

The drawback, of course, is that you now have one mega-function that knows about all the classes used by your program. That's what DI frameworks can help with. But if you're having trouble understanding why this approach is valuable, I'd recommend starting with manual dependency injection first, so you can better appreciate what the various frameworks out there can do for you.

Struggled to solve this one, checked the load order and if jQuery was included twice via bundling, but that didn't seem to be the cause.

Finally fixed it by making the following change:

(before):

$('#myModal').modal('hide');

(after):

window.$('#myModal').modal('hide');

You will be presented with the MD5, SHA1, and SHA256 keys; Choose the one you need.

As far as the http verb is concerned the WebRequest might be easier. You could go for something like:

    WebRequest r = WebRequest.Create("http://some.url");
    r.Method = "POST";
    using (var s = r.GetResponse().GetResponseStream())
    {
        using (var reader = new StreamReader(r, FileMode.Open))
        {
            var content = reader.ReadToEnd();
        }
    }

Obviously this lacks exception handling and writing the request body (for which you can use r.GetRequestStream() and write it like a regular stream, but I hope it may be of some help.

Since you can just create and throw exceptions it could be as easy as

if ( word.contains(" ") )
{
     throw new RuntimeException ( "Word contains one or more spaces" ) ;
}

If you would like to be more formal, you can create an Exception class

class SpaceyWordException extends RuntimeException
{

}

Either way, if you use RuntimeException, your new Exception will be unchecked.

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

package com.example;
import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
public class StrongAES 
{
    public void run() 
    {
        try 
        {
            String text = "Hello World";
            String key = "Bar12345Bar12345"; // 128 bit key
            // Create key and cipher
            Key aesKey = new SecretKeySpec(key.getBytes(), "AES");
            Cipher cipher = Cipher.getInstance("AES");
            // encrypt the text
            cipher.init(Cipher.ENCRYPT_MODE, aesKey);
            byte[] encrypted = cipher.doFinal(text.getBytes());
            System.err.println(new String(encrypted));
            // decrypt the text
            cipher.init(Cipher.DECRYPT_MODE, aesKey);
            String decrypted = new String(cipher.doFinal(encrypted));
            System.err.println(decrypted);
        }
        catch(Exception e) 
        {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) 
    {
        StrongAES app = new StrongAES();
        app.run();
    }
}

Tomcat can tell you in several ways. Here's the easiest:

 $ /path/to/catalina.sh version
Using CATALINA_BASE:   /usr/local/apache-tomcat-7.0.29
Using CATALINA_HOME:   /usr/local/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
Using CLASSPATH:       /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.29
Server built:   Jul 3 2012 11:31:52
Server number:  7.0.29.0
OS Name:        Mac OS X
OS Version:     10.7.4
Architecture:   x86_64
JVM Version:    1.6.0_33-b03-424-11M3720
JVM Vendor:     Apple Inc.

If you don't know where catalina.sh is (or it never gets called), you can usually find it via ps:

$ ps aux | grep catalina
chris            930   0.0  3.1  2987336 258328 s000  S    Wed01PM   2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start

From the ps output, you can see both catalina.home and catalina.base. catalina.home is where the Tomcat base files are installed, and catalina.base is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.

You can also interrogate the JVM directly if you can't find it in a ps listing:

$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29

If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home and catalina.base.

Yes it's possible. Look!

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

But why would you want to?

As stated before - VueJS simply can't track those operations(array elements assignment). All operations that are tracked by VueJS with array are here. But I'll copy them once again:

• push()
• pop()
• shift()
• unshift()
• splice()
• sort()
• reverse()

During development, you face a problem - how to live with that :).

push(), pop(), shift(), unshift(), sort() and reverse() are pretty plain and help you in some cases but the main focus lies within the splice(), which allows you effectively modify the array that would be tracked by VueJs. So I can share some of the approaches, that are used the most working with arrays.

You need to replace Item in Array:

// note - findIndex might be replaced with some(), filter(), forEach() 
// or any other function/approach if you need 
// additional browser support, or you might use a polyfill
const index = this.values.findIndex(item => {
          return (replacementItem.id === item.id)
        })
this.values.splice(index, 1, replacementItem)

Note: if you just need to modify an item field - you can do it just by:

this.values[index].itemField = newItemFieldValue

And this would be tracked by VueJS as the item(Object) fields would be tracked.

You need to empty the array:

this.values.splice(0, this.values.length)

Actually you can do much more with this function splice() - w3schools link You can add multiple records, delete multiple records, etc.

Vue.set() and Vue.delete()

Vue.set() and Vue.delete() might be used for adding field to your UI version of data. For example, you need some additional calculated data or flags within your objects. You can do this for your objects, or list of objects(in the loop):

 Vue.set(plan, 'editEnabled', true) //(or this.$set)

And send edited data back to the back-end in the same format doing this before the Axios call:

 Vue.delete(plan, 'editEnabled') //(or this.$delete)

Just order by count(*) desc and you'll get the highest (if you combine it with limit 1)

Just import following package,

import org.hibernate.cfg.Configuration;

Error was solved!!!

Using Apollo Server 2.

Per https://github.com/apollographql/apollo-client/issues/4778#issuecomment-509638071, this solved my problem:

try 'ws://localhost:4000/graphql'

...since incoming and outgoing requests now use the same address.

Here's a way to do it:

// The method to call
void Foo()
{
}


Action action = Foo;
action.BeginInvoke(ar => action.EndInvoke(ar), null);

Of course you need to replace Action by another type of delegate if the method has a different signature

Instead of copy/paste a unicode character or setting it in the code-behind you could also change the properties of the TextBox. Simply set "UseSystemPasswordChar" to True and everytghing will be done for you by the Framework. Or in code-behind:

this.txtPassword.UseSystemPasswordChar = true;

I think the easiest fix to this is to self ping your own server every 30 mins. Here's the code I use in my node.js project to prevent sleeping.

const request = require('request');
const ping = () => request('https://<my-app-name>.herokuapp.com/', (error, response, body) => {
    console.log('error:', error); // Print the error if one occurred
    console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
    console.log('body:', body); // Print body of response received
});
setInterval(ping, 20*60*1000); // I have set to 20 mins interval

While it is nowhere nearly as clean, but you could implement something like C# delegates using a Java Proxy.

1. Edit registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\python.exe\default
2. Set default program to open .py files to python.exe

In Objective-C, a selector's signature consists of:

1. The name of the method (in this case it would be 'myTest') (required)
2. A ':' (colon) following the method name if the method has an input.
3. A name and ':' for every additional input.

Selectors have no knowledge of:

1. The input types
2. The method's return type.

Here's a class implementation where performMethodsViaSelectors method performs the other class methods by way of selectors:

@implementation ClassForSelectors
- (void) fooNoInputs {
    NSLog(@"Does nothing");
}
- (void) fooOneIput:(NSString*) first {
    NSLog(@"Logs %@", first);
}
- (void) fooFirstInput:(NSString*) first secondInput:(NSString*) second {
    NSLog(@"Logs %@ then %@", first, second);
}
- (void) performMethodsViaSelectors {
    [self performSelector:@selector(fooNoInputs)];
    [self performSelector:@selector(fooOneInput:) withObject:@"first"];
    [self performSelector:@selector(fooFirstInput:secondInput:) withObject:@"first" withObject:@"second"];
}
@end

The method you want to create a selector for has a single input, so you would create a selector for it like so:

SEL myTestSelector = @selector(myTest:);

Use this to solve your problem:
