Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

Let me know if you have a problem.

Since nullptr is never going to be returned, I recommend the reference approach. It more accurately represents how the return value will be used.

git checkout master should do the trick. To go back two versions, you could say something like git checkout HEAD~2, but better to create a temporary branch based on that time, so git checkout -b temp_branch HEAD~2

The solution to the problem is:

1. Find the .gitconfig file

2. [user] name = 1wQasdTeedFrsweXcs234saS56Scxs5423 email = [email protected] [credential] helper = osxkeychain [url ""] insteadOf = git:// [url "https://"] [url "https://"] insteadOf = git://

there would be a blank url="" replace it with url="https://"

[user]
    name = 1wQasdTeedFrsweXcs234saS56Scxs5423
    email = [email protected]
[credential]
    helper = osxkeychain
[url "https://"]
    insteadOf = git://
[url "https://"]
[url "https://"]
    insteadOf = git://

This will work :)

Happy Bower-ing

Try moving the button styling to the TouchableHighlight itself:

Styles:

  submit:{
    marginRight:40,
    marginLeft:40,
    marginTop:10,
    paddingTop:20,
    paddingBottom:20,
    backgroundColor:'#68a0cf',
    borderRadius:10,
    borderWidth: 1,
    borderColor: '#fff'
  },
  submitText:{
      color:'#fff',
      textAlign:'center',
  }

Button (same):

<TouchableHighlight
  style={styles.submit}
  onPress={() => this.submitSuggestion(this.props)}
  underlayColor='#fff'>
    <Text style={[this.getFontSize(),styles.submitText]}>Submit</Text>
</TouchableHighlight>

I had the same issue and was not satisfied with any of the answers so far since none of them guaranteed unique IDs.

I too wanted to print object IDs for debugging purposed. I knew there must be some way to do it, because in the Eclipse debugger, it specifies unique IDs for each object.

I came up with a solution based on the fact that the "==" operator for objects only returns true if the two objects are actually the same instance.

import java.util.HashMap;
import java.util.Map;

/**
 *  Utility for assigning a unique ID to objects and fetching objects given
 *  a specified ID
 */
public class ObjectIDBank {

    /**Singleton instance*/
    private static ObjectIDBank instance;

    /**Counting value to ensure unique incrementing IDs*/
    private long nextId = 1;

    /** Map from ObjectEntry to the objects corresponding ID*/
    private Map<ObjectEntry, Long> ids = new HashMap<ObjectEntry, Long>();

    /** Map from assigned IDs to their corresponding objects */
    private Map<Long, Object> objects = new HashMap<Long, Object>();

    /**Private constructor to ensure it is only instantiated by the singleton pattern*/
    private ObjectIDBank(){}

    /**Fetches the singleton instance of ObjectIDBank */
    public static ObjectIDBank instance() {
        if(instance == null)
            instance = new ObjectIDBank();

        return instance;
    }

    /** Fetches a unique ID for the specified object. If this method is called multiple
     * times with the same object, it is guaranteed to return the same value. It is also guaranteed
     * to never return the same value for different object instances (until we run out of IDs that can
     * be represented by a long of course)
     * @param obj The object instance for which we want to fetch an ID
     * @return Non zero unique ID or 0 if obj == null
     */
    public long getId(Object obj) {

        if(obj == null)
            return 0;

        ObjectEntry objEntry = new ObjectEntry(obj);

        if(!ids.containsKey(objEntry)) {
            ids.put(objEntry, nextId);
            objects.put(nextId++, obj);
        }

        return ids.get(objEntry);
    }

    /**
     * Fetches the object that has been assigned the specified ID, or null if no object is
     * assigned the given id
     * @param id Id of the object
     * @return The corresponding object or null
     */
    public Object getObject(long id) {
        return objects.get(id);
    }


    /**
     * Wrapper around an Object used as the key for the ids map. The wrapper is needed to
     * ensure that the equals method only returns true if the two objects are the same instance
     * and to ensure that the hash code is always the same for the same instance.
     */
    private class ObjectEntry {
        private Object obj;

        /** Instantiates an ObjectEntry wrapper around the specified object*/
        public ObjectEntry(Object obj) {
            this.obj = obj;
        }


        /** Returns true if and only if the objects contained in this wrapper and the other
         * wrapper are the exact same object (same instance, not just equivalent)*/
        @Override
        public boolean equals(Object other) {
            return obj == ((ObjectEntry)other).obj;
        }


        /**
         * Returns the contained object's identityHashCode. Note that identityHashCode values
         * are not guaranteed to be unique from object to object, but the hash code is guaranteed to
         * not change over time for a given instance of an Object.
         */
        @Override
        public int hashCode() {
            return System.identityHashCode(obj);
        }
    }
}

I believe that this should ensure unique IDs throughout the lifetime of the program. Note, however, that you probably don't want to use this in a production application because it maintains references to all of the objects for which you generate IDs. This means that any objects for which you create an ID will never be garbage collected.

Since I'm using this for debug purposes, I'm not too concerned with the memory being freed.

You could modify this to allow clearing Objects or removing individual objects if freeing memory is a concern.

You can try:

ls -lru

-u with -lt: sort by, and show, access time;

I got this error when I installed Laravel 5.5 on my digitalocean cloud server (Ubuntu 18.04 and PHP 7.2) and the following command fixed it.

sudo apt install zip unzip php7.2-zip

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

You can just as easily access each element in the list using e.g. path[[1]]. You can't put a set of matrices into an atomic vector and access each element. A matrix is an atomic vector with dimension attributes. I would use the list structure returned by split, it's what it was designed for. Each list element can hold data of different types and sizes so it's very versatile and you can use *apply functions to further operate on each element in the list. Example below.

#  For reproducibile data
set.seed(1)

#  Make some data
userid <- rep(1:2,times=4)
data1 <- replicate(8 , paste( sample(letters , 3 ) , collapse = "" ) )
data2 <- sample(10,8)
df <- data.frame( userid , data1 , data2 )

#  Split on userid
out <- split( df , f = df$userid )
#$`1`
#  userid data1 data2
#1      1   gjn     3
#3      1   yqp     1
#5      1   rjs     6
#7      1   jtw     5

#$`2`
#  userid data1 data2
#2      2   xfv     4
#4      2   bfe    10
#6      2   mrx     2
#8      2   fqd     9

Access each element using the [[ operator like this:

out[[1]]
#  userid data1 data2
#1      1   gjn     3
#3      1   yqp     1
#5      1   rjs     6
#7      1   jtw     5

Or use an *apply function to do further operations on each list element. For instance, to take the mean of the data2 column you could use sapply like this:

sapply( out , function(x) mean( x$data2 ) )
#   1    2 
#3.75 6.25 

for my script of python, I use...

To START python script :

start-stop-daemon --start --background --pidfile $PIDFILE --make-pidfile --exec $DAEMON

To STOP python script :

PID=$(cat $PIDFILE)
kill -9 $PID
rm -f $PIDFILE

P.S.: sorry for poor English, I'm from CHILE :D

Return output first true value.

If all are false return last false value.

Example:-

  null || undefined || false || 0 || 'apple'  // Return apple

None of the answers above work if your variable:

• starts with -e
• starts with -n
• starts with -E
• contains a \ followed by an n
• should not have an extra newline appended after it

and so they cannot be relied upon for arbitrary string contents.

In bash, you can use "here strings" as:

cat <<< "$var" > "$destdir"

As noted in the comment below, @Trebawa's answer (formulated in the same room as mine!) using printf is a better approach.

Well it seems that you are missing a reference to some library. I had the similar error solved it by adding a reference to the #pragma comment(lib, "windowscodecs.lib")

In addition, if you want to refer to the root directory, you can use:

/

Which will refer to the root. So, let's say we're in a file that's nested within a few levels of folders and you want to go back to the main index.html:

<a href="/index.html">My Index Page</a>

Robert is spot-on with further relative path explanations.

I made some big lists. One is a list and one is a numpy array.

import numpy as np
import random
arrayv=np.random.randint(0,10,(100000000,1))
listv=[]
for i in range(0,100000000):
    listv.append(random.randint(0,9))

Using jupyter notebook's %%time function I can compare the speed of various things.

2 seconds:

%%time
listv.index(max(listv))

54.6 seconds:

%%time
listv.index(max(arrayv))

6.71 seconds:

%%time
np.argmax(listv)

103 ms:

%%time
np.argmax(arrayv)

numpy's arrays are crazy fast.

as you write the it with double-quotes, you don't need to escape spaces with \

export PATH=$PATH:"/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/"

of course this also works:

export PATH=$PATH:/cygdrive/C/Program\ Files/Java/jdk1.6.0_23/bin/

a = [[] for index in range(1, n)]

A other users suggested,

.empty()

is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.

If you wish to keep data, like event handlers for example, you should use

.detach()

as described on the JQuery's API detach documentation.

The method .remove() could be usefull for similar purposes.

Use following commnad with your version number

nvm install v8.9
nvm alias default  v8.9
nvm use v8.9

Another way to go

const data: {[key: string]: any} = require('./data.json');

This was you still can define json type is you want and don't have to use wildcard.

For example, custom type json.

interface User {
  firstName: string;
  lastName: string;
  birthday: Date;
}
const user: User = require('./user.json');

This might be useful for refreshing also. But if you want to keep track of position on the page before you click on a same position.. The following code will help.

Also added a data-confirm for prompting the user if they really want to do that..

Note: I'm using jQuery and js-cookie.js to store cookie info.

$(document).ready(function() {
    // make all links with data-confirm prompt the user first.
    $('[data-confirm]').on("click", function (e) {
        e.preventDefault();
        var msg = $(this).data("confirm");
        if(confirm(msg)==true) {
            var url = this.href;
            if(url.length>0) window.location = url;
            return true;
        }
        return false;
    });

    // on certain links save the scroll postion.
    $('.saveScrollPostion').on("click", function (e) {
        e.preventDefault();
        var currentYOffset = window.pageYOffset;  // save current page postion.
        Cookies.set('jumpToScrollPostion', currentYOffset);
        if(!$(this).attr("data-confirm")) {  // if there is no data-confirm on this link then trigger the click. else we have issues.
            var url = this.href;
            window.location = url;
            //$(this).trigger('click');  // continue with click event.
        }
    });

    // check if we should jump to postion.
    if(Cookies.get('jumpToScrollPostion') !== "undefined") {
        var jumpTo = Cookies.get('jumpToScrollPostion');
        window.scrollTo(0, jumpTo);
        Cookies.remove('jumpToScrollPostion');  // and delete cookie so we don't jump again.
    }
});

A example of using it like this.

<a href='gotopage.html' class='saveScrollPostion' data-confirm='Are you sure?'>Goto what the heck</a>

This Answer seems to be

bit helpful while declaring the large numbe of variable in the function

Laravel 5.7.*

For Example

public function index()
{
    $activePost = Post::where('status','=','active')->get()->count();

    $inActivePost = Post::where('status','=','inactive')->get()->count();

    $yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();

    $todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();

    return view('dashboard.index')->with('activePost',$activePost)->with('inActivePost',$inActivePost )->with('yesterdayPostActive',$yesterdayPostActive )->with('todayPostActive',$todayPostActive );
}

When you see the last line of the returns it not looking good

When You Project is Getting Larger its not good

So

public function index()
    {
        $activePost = Post::where('status','=','active')->get()->count();

        $inActivePost = Post::where('status','=','inactive')->get()->count();

        $yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();

        $todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();

        $viewShareVars = ['activePost','inActivePost','yesterdayPostActive','todayPostActive'];

        return view('dashboard.index',compact($viewShareVars));
    }

As You see all the variables as declared as array of $viewShareVars and Accessed in View

But My Function Becomes very Larger so i have decided to make the line as very simple

public function index()
    {
        $activePost = Post::where('status','=','active')->get()->count();

        $inActivePost = Post::where('status','=','inactive')->get()->count();

        $yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();

        $todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();

        $viewShareVars = array_keys(get_defined_vars());

        return view('dashboard.index',compact($viewShareVars));
    }

the native php function get_defined_vars() get all the defined variables from the function

and array_keys will grab the variable names

so in your view you can access all the declared variable inside the function

as {{$todayPostActive}}

For dynamically setting state properties for form inputs and keeping them controlled you could do something like this:

const inputs = [
    { name: 'email', type: 'email', placeholder: "Enter your email"},
    { name: 'password', type: 'password', placeholder: "Enter your password"},
    { name: 'passwordConfirm', type: 'password', placeholder: "Confirm your password"},
]

class Form extends Component {
  constructor(props){
    super(props)
    this.state = {} // Notice no explicit state is set in the constructor
  }

  handleChange = (e) => {
    const { name, value } = e.target;

    this.setState({
      [name]: value
    }
  }

  handleSubmit = (e) => {
    // do something
  }

  render() {
     <form onSubmit={(e) => handleSubmit(e)}>
       { inputs.length ?
         inputs.map(input => {
           const { name, placeholder, type } = input;
           const value = this.state[name] || ''; // Does it exist? If so use it, if not use an empty string

           return <input key={name}  type={type} name={name} placeholder={placeholder} value={value} onChange={this.handleChange}/>
       }) :
         null
       }
       <button type="submit" onClick={(e) => e.preventDefault }>Submit</button>
     </form>    
  }
}

That's probably as fast as you can do it in pure python for reasonably large inputs:

def choose(n, k):
    if k == n: return 1
    if k > n: return 0
    d, q = max(k, n-k), min(k, n-k)
    num =  1
    for n in xrange(d+1, n+1): num *= n
    denom = 1
    for d in xrange(1, q+1): denom *= d
    return num / denom

I had the same issue on Ubuntu(14.04) with Jupyter.

To solve it I've added the dot library to python sys.path

First: check if dot is installed,

Then: find his path whereis dot -> /local/notebook/miniconda2/envs/ik2/bin/dot

Finally in python script : sys.path.append("/local/notebook/miniconda2/envs/ik2/bin/dot")

EDIT: From ECMAScript 2018 onwards, lookbehind assertions (even unbounded) are supported natively.

In previous versions, you can do this:

^(?:(?!filename\.js$).)*\.js$

This does explicitly what the lookbehind expression is doing implicitly: check each character of the string if the lookbehind expression plus the regex after it will not match, and only then allow that character to match.

^                 # Start of string
(?:               # Try to match the following:
 (?!              # First assert that we can't match the following:
  filename\.js    # filename.js 
  $               # and end-of-string
 )                # End of negative lookahead
 .                # Match any character
)*                # Repeat as needed
\.js              # Match .js
$                 # End of string

Another edit:

It pains me to say (especially since this answer has been upvoted so much) that there is a far easier way to accomplish this goal. There is no need to check the lookahead at every character:

^(?!.*filename\.js$).*\.js$

works just as well:

^                 # Start of string
(?!               # Assert that we can't match the following:
 .*               # any string, 
  filename\.js    # followed by filename.js
  $               # and end-of-string
)                 # End of negative lookahead
.*                # Match any string
\.js              # Match .js
$                 # End of string

It is indeed a foreign key error, you can find out using perror:

shell$ perror 150
MySQL error code 150: Foreign key constraint is incorrectly formed

To find out more details about what failed, you can use SHOW ENGINE INNODB STATUS and look for the LATEST FOREIGN KEY ERROR section it contains details about what is wrong.

In your case, it is most likely cause something is referencing the country_id column.

In addition to options suggested by others I can recommend the fmt library which implements string formatting similar to str.format in Python and String.Format in C#. Here's an example:

std::string a = "test";
std::string b = "text.txt";
std::string c = "text1.txt";
std::string result = fmt::format("{0} {1} > {2}", a, b, c);

Disclaimer: I'm the author of this library.

Use the function GetSize from the module cv with your image as parameter. It returns width, height as a tuple with 2 elements:

width, height = cv.GetSize(src)

The error says that a warning was treated as an error, therefore your problem is a warning message! The object file is then not created because there was an error. So you need to check your warnings and fix them.

In case you don't know how to find them: Open the Error List (View > Error List) and click on Warning.

What worked me is that I copied all the code inside the broken class and removed that file. Then, I opened an empty file with the same name and pasted back.

Result: beautiful syntax highlights came back!

Problem with the above answer comes with files input with "./" like "./my-file.txt"

Workaround (of many):

    myfile="./somefile.txt"
    FOLDER="$(dirname $(readlink -f "${ARG}"))"
    echo ${FOLDER}

CONVERT(VARCHAR,GETDATE(),120)

using System.Linq;

...

double total = myList.Sum(item => item.Amount);

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

As far as I know Python runs off of the commandline using the PATH variable as opposed to a registry setting.

So if you point to the correct version on your PATH you will use that. Remember to restart your command prompt to use the new PATH settings.

You can set selinux to permissive in order to analyze.

    # setenforce 0

Selinux will log but permit acesses. So you can check the /var/log/audit/audit.log for details. Maybe you will need change selinux context. Fot this, you will use chcon command. If you need, show us your audit.log to more detailed answer.

Don't forget to enable selinux after you solved the problem. It better keep selinux enforced.

    # setenforce 1

I've covered this in a pet project.. use what you want.

Note that the ListEx implements the IDataReader interface.

people = new ListExCommand(command)
.Map(p=> new ContactPerson()
{
  Age = p.GetInt32(p.GetOrdinal("Age")),
  FirstName = p.GetString(p.GetOrdinal("FirstName")),
  IdNumber = p.GetInt64(p.GetOrdinal("IdNumber")),
  Surname = p.GetString(p.GetOrdinal("Surname")),
  Email = "[email protected]"
})
.ToListEx()
.Where("FirstName", "Peter");

Or use object mapping like in the following example.

people = new ListExAutoMap(personList)
.Map(p => new ContactPerson()
{
    Age = p.Age,
    FirstName = p.FirstName,
    IdNumber = p.IdNumber,
    Surname = p.Surname,
    Email = "[email protected]"
})
.ToListEx()
.Where(contactPerson => contactPerson.FirstName == "Zack");

Have a look at http://caprisoft.codeplex.com

In addition to your CORS issue, the server you are trying to access has HTTP basic authentication enabled. You can include credentials in your cross-domain request by specifying the credentials in the URL you pass to the XHR:

url = 'http://username:[email protected]/testpage'

document.getElementById("PdfContentArea").setAttribute('data', path);

OR

var objectEl = document.getElementById("PdfContentArea")

objectEl.outerHTML = objectEl.outerHTML.replace(/data="(.+?)"/, 'data="' + path + '"');

In such cases, you can convert the values of enum to a List and stream through it. Something like below examples. I would recommend using filter().

Using ForEach:

List<Category> category = Arrays.asList(Category.values());
category.stream().forEach(eachCategory -> {
            if(eachCategory.toString().equals("3")){
                String name = eachCategory.name();
            }
        });

Or, using Filter:

When you want to find with code:

List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.toString().equals("3")).findAny().orElse(null);

System.out.println(category.toString() + " " + category.name());

When you want to find with name:

List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.name().equals("Apple")).findAny().orElse(null);

System.out.println(category.toString() + " " + category.name());

Hope it helps! I know this is a very old post, but someone can get help.

1- Traditional way

The traditional conversion way is through using read() method of InputStream as the following:

public static byte[] convertUsingTraditionalWay(File file)
{
    byte[] fileBytes = new byte[(int) file.length()]; 
    try(FileInputStream inputStream = new FileInputStream(file))
    {
        inputStream.read(fileBytes);
    }
    catch (Exception ex) 
    {
        ex.printStackTrace();
    }
    return fileBytes;
}

2- Java NIO

With Java 7, you can do the conversion using Files utility class of nio package:

public static byte[] convertUsingJavaNIO(File file)
{
    byte[] fileBytes = null;
    try
    {
        fileBytes = Files.readAllBytes(file.toPath());
    }
    catch (Exception ex) 
    {
        ex.printStackTrace();
    }
    return fileBytes;
}

3- Apache Commons IO

Besides JDK, you can do the conversion using Apache Commons IO library in 2 ways:

3.1. IOUtils.toByteArray()

public static byte[] convertUsingIOUtils(File file)
{
    byte[] fileBytes = null;
    try(FileInputStream inputStream = new FileInputStream(file))
    {
        fileBytes = IOUtils.toByteArray(inputStream);
    }
    catch (Exception ex) 
    {
        ex.printStackTrace();
    }
    return fileBytes;
}

3.2. FileUtils.readFileToByteArray()

public static byte[] convertUsingFileUtils(File file)
{
    byte[] fileBytes = null;
    try
    {
        fileBytes = FileUtils.readFileToByteArray(file);
    }
    catch(Exception ex)
    {
        ex.printStackTrace();
    }
    return fileBytes;
}

If You're using php5.6 and Ubuntu 18.04 Then run these two commands in your terminal your errors will be solved definitely.

sudo apt-get install php5.6-gd

then restart your apache server by this command.

 sudo service apache2 restart

Simply, static functions function independently of the class where they belong.

$this means, this is an object of this class. It does not apply to static functions.

class test {
    public function sayHi($hi = "Hi") {
        $this->hi = $hi;
        return $this->hi;
    }
}
class test1 {
    public static function sayHi($hi) {
        $hi = "Hi";
        return $hi;
    }
}

//  Test
$mytest = new test();
print $mytest->sayHi('hello');  // returns 'hello'
print test1::sayHi('hello');    //  returns 'Hi'

Interfaces do not contain any implementation.

1. Define an interface with a property.
2. Further you can implement that interface in any class and use this class going forward.
3. If required you can have this property defined as virtual in the class so that you can modify its behaviour.

I'm assuming you are using m2eclipse as you mentioned it. However it is not clear whether you created your project under Eclipse or not so I'll try to cover all cases.

1. If you created a "Java" project under Eclipse (Ctrl+N > Java Project), then right-click the project in the Package Explorer view and go to Maven > Enable Dependency Management (depending on the initial project structure, you may have modify it to match the maven's one, for example by adding src/java to the source folders on the build path).

2. If you created a "Maven Project" under Eclipse (Ctrl+N > Maven Project), then it should be already "Maven ready".

3. If you created a Maven project outside Eclipse (manually or with an archetype), then simply import it in Eclipse (right-click the Package Explorer view and select Import... > Maven Projects) and it will be "Maven ready".

Now, to add a dependency, either right-click the project and select Maven > Add Dependency) or edit the pom manually.

PS: avoid using the maven-eclipse-plugin if you are using m2eclipse. There is absolutely no need for it, it will be confusing, it will generate some mess. No, really, don't use it unless you really know what you are doing.

Make your laptop a wifi hotspot for your phone (any) and connect it to internet. Sniff Traffic on your wifi interface using wireshark.

you will get to know a lot of anti privacy stuff!

Not sure if this is relevant but I had the same problem with Fiddler after the last update (v2.4.5.0). I turned all filters off but still wasn't picking up any traffic. When I unchecked Use Filters on the filters tab, however, all traffic was picked up as normal. I'm still trying to figure out how I can use filters when just checking Use Filters box causes all traffic to be blocked.

Git doesn't store file permissions other than executable scripts. Consider using something like git-cache-meta to save file ownership and permissions.

Git can only store two types of modes: 755 (executable) and 644 (not executable). If your file was 444 git would store it has 644.

You can get the size of your Mysql database by running the following command in Mysql client

SELECT  sum(round(((data_length + index_length) / 1024 / 1024 / 1024), 2))  as "Size in GB"
FROM information_schema.TABLES
WHERE table_schema = "<database_name>"

Double is a wrapper class,

The Double class wraps a value of the primitive type double in an object. An object of type Double contains a single field whose type is double.

In addition, this class provides several methods for converting a double to a String and a String to a double, as well as other constants and methods useful when dealing with a double.

The double data type,

The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is 4.94065645841246544e-324d to 1.79769313486231570e+308d (positive or negative). For decimal values, this data type is generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.

Check each datatype with their ranges : Java's Primitive Data Types.

Important Note : If you'r thinking to use double for precise values, you need to re-think before using it. Java Traps: double

A couple of general tips (besides the DOS line ending issue):

cat is for concatenating files, it's not the only tool that can read files! If a command doesn't read files then use redirection like command < file.

You can set the field separator with the -F option so instead of:

cat foo | awk 'BEGIN{FS="|"} {print $2 " " $1}' 

Try:

awk -F'|' '{print $2" "$1}' foo 

This will output:

com.emailclient.account [email protected]
com.socialsite.auth.accoun [email protected]

To get the desired output you could do a variety of things. I'd probably split() the second field:

awk -F'|' '{split($2,a,".");print a[2]" "$1}' file
emailclient [email protected]
socialsite [email protected]

Finally to get the first character converted to uppercase is a bit of a pain in awk as you don't have a nice built in ucfirst() function:

awk -F'|' '{split($2,a,".");print toupper(substr(a[2],1,1)) substr(a[2],2),$1}' file
Emailclient [email protected]
Socialsite [email protected]

If you want something more concise (although you give up a sub-process) you could do:

awk -F'|' '{split($2,a,".");print a[2]" "$1}' file | sed 's/^./\U&/'
Emailclient [email protected]
Socialsite [email protected]

Please note that the problem is not white color. It is because it is being transparent.

When an element is made transparent, all of its child element's opacity; alpha filter in IE 6 7 etc, is changed to the new value.

So you cannot say that it is white!

You can place an element above it, and change that element's transparency to 1 while changing the image's transparency to .2 or what so ever you want to.

Step 1 is always to first determine where the problem lies. Your title and most of your question seem to suggest that you're running into quite a low length limit on the length of a string in JavaScript / on browsers, an improbably low limit. You're not. Consider:

var str;

document.getElementById('theButton').onclick = function() {
  var build, counter;

  if (!str) {
    str = "0123456789";
    build = [];
    for (counter = 0; counter < 900; ++counter) {
      build.push(str);
    }
    str = build.join("");
  }
  else {
    str += str;
  }
  display("str.length = " + str.length);
};

Live copy

Repeatedly clicking the relevant button keeps making the string longer. With Chrome, Firefox, Opera, Safari, and IE, I've had no trouble with strings more than a million characters long:

str.length = 9000
str.length = 18000
str.length = 36000
str.length = 72000
str.length = 144000
str.length = 288000
str.length = 576000
str.length = 1152000
str.length = 2304000
str.length = 4608000
str.length = 9216000
str.length = 18432000

...and I'm quite sure I could got a lot higher than that.

So it's nothing to do with a length limit in JavaScript. You haven't show your code for sending the data to the server, but most likely you're using GET which means you're running into the length limit of a GET request, because GET parameters are put in the query string. Details here.

You need to switch to using POST instead. In a POST request, the data is in the body of the request rather than in the URL, and can be very, very large indeed.

For integers you can use Integer.signum()

Returns the signum function of the specified int value. (The return value is -1 if the specified value is negative; 0 if the specified value is zero; and 1 if the specified value is positive.)

Check your servers error log, typically /var/log/apache2/error.log.

In ~/.subversion/auth/svn.simple/ you should find a file with a long hexadecimal name. The password is in there in plaintext.

If there is more than one file you'll need to find that one that references the server you need the password for.

The HTTP specification (RFC 2616) has a number of recommendations that are applicable. Here is my interpretation:

• HTTP status code 200 OK for a successful PUT of an update to an existing resource. No response body needed. (Per Section 9.6, 204 No Content is even more appropriate.)
• HTTP status code 201 Created for a successful PUT of a new resource, with the most specific URI for the new resource returned in the Location header field and any other relevant URIs and metadata of the resource echoed in the response body. (RFC 2616 Section 10.2.2)
• HTTP status code 409 Conflict for a PUT that is unsuccessful due to a 3^rd-party modification, with a list of differences between the attempted update and the current resource in the response body. (RFC 2616 Section 10.4.10)
• HTTP status code 400 Bad Request for an unsuccessful PUT, with natural-language text (such as English) in the response body that explains why the PUT failed. (RFC 2616 Section 10.4)

In terms of pattern interpretation, there's no difference between the following forms:

• /pattern/
• new RegExp("pattern")

If you want to replace a literal string using the replace method, I think you can just pass a string instead of a regexp to replace.

Otherwise, you'd have to escape any regexp special characters in the pattern first - maybe like so:

function reEscape(s) {
    return s.replace(/([.*+?^$|(){}\[\]])/mg, "\\$1");
}

// ...

var re = new RegExp(reEscape(pattern), "mg");
this.markup = this.markup.replace(re, value);

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

Check it out in this demo fiddle, go ahead and change the dropdown or default values in the code.

Setting the passenger.Title with a value that equals to a title.Value should work.

View:

<select [(ngModel)]="passenger.Title">
    <option *ngFor="let title of titleArray" [value]="title.Value">
      {{title.Text}}
    </option>
</select>

TypeScript used:

class Passenger {
  constructor(public Title: string) { };
}
class ValueAndText {
  constructor(public Value: string, public Text: string) { }
}

...
export class AppComponent {
    passenger: Passenger = new Passenger("Lord");

    titleArray: ValueAndText[] = [new ValueAndText("Mister", "Mister-Text"),
                                  new ValueAndText("Lord", "Lord-Text")];

}

Class<?> cls = Class.forName(className);

But your className should be fully-qualified - i.e. com.mycompany.MyClass

You can use file prefix to load the external application context file some thing like this

  <context:property-placeholder location="file:///C:/Applications/external/external.properties"/>

Patching wasn't working for me, for whatever reason, so I had to resort to this method:

import { of } from 'rxjs/observable/of'

// ...

return of(res)

According to the Java Virtual Machine Specification (Java SE 8), JVM §4.3.2. Field Descriptors:

FieldType term | Type      | Interpretation
-------------- | --------- | --------------
L ClassName ;  | reference | an instance of class ClassName
[              | reference | one array dimension
...            | ...       | ...

the expression [Ljava.lang.String;@45a877 means this is an array ( [ ) of class java.lang.String ( Ljava.lang.String; ). And @45a877 is the address where the String object is stored in memory.

Since I haven't seen an answer that deal with numerical and non-numerical attributes, here is a complement answer.

You might want to drop the outliers only on numerical attributes (categorical variables can hardly be outliers).

Function definition

I have extended @tanemaki's suggestion to handle data when non-numeric attributes are also present:

from scipy import stats

def drop_numerical_outliers(df, z_thresh=3):
    # Constrains will contain `True` or `False` depending on if it is a value below the threshold.
    constrains = df.select_dtypes(include=[np.number]) \
        .apply(lambda x: np.abs(stats.zscore(x)) < z_thresh, reduce=False) \
        .all(axis=1)
    # Drop (inplace) values set to be rejected
    df.drop(df.index[~constrains], inplace=True)

Usage

drop_numerical_outliers(df)

Example

Imagine a dataset df with some values about houses: alley, land contour, sale price, ... E.g: Data Documentation

First, you want to visualise the data on a scatter graph (with z-score Thresh=3):

# Plot data before dropping those greater than z-score 3. 
# The scatterAreaVsPrice function's definition has been removed for readability's sake.
scatterAreaVsPrice(df)

# Drop the outliers on every attributes
drop_numerical_outliers(train_df)

# Plot the result. All outliers were dropped. Note that the red points are not
# the same outliers from the first plot, but the new computed outliers based on the new data-frame.
scatterAreaVsPrice(train_df)

Try this:

delete from your_table;    
delete from sqlite_sequence where name='your_table';

SQLite Autoincrement

SQLite keeps track of the largest ROWID that a table has ever held using the special SQLITE_SEQUENCE table. The SQLITE_SEQUENCE table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.

If you want to write a graphical UI in bash, zenity is the way to go. This is what you can do with it:

Application Options:
  --calendar                                     Display calendar dialog
  --entry                                        Display text entry dialog
  --error                                        Display error dialog
  --info                                         Display info dialog
  --file-selection                               Display file selection dialog
  --list                                         Display list dialog
  --notification                                 Display notification
  --progress                                     Display progress indication dialog
  --question                                     Display question dialog
  --warning                                      Display warning dialog
  --scale                                        Display scale dialog
  --text-info                                    Display text information dialog

Combining these widgets you can create pretty usable GUIs. Of course, it's not as flexible as a toolkit integrated into a programming language, but in some cases it's really useful.

I dislike the chaining thens. The second then does not have access to status. As stated before 'response.json()' returns a promise. Returning the then result of 'response.json()' in a acts similar to a second then. It has the added bonus of being in scope of the response.

return fetch(url, params).then(response => {
    return response.json().then(body => {
        if (response.status === 200) {
            return body
        } else {
            throw body
        }
    })
})

Had the same issues getting an authorization token on my Nexus 5 on Windows 8.1. I didn't have the latest adb driver installed - this is visible in device manager. Downloaded the latest ADB USB driver from Google here: http://developer.android.com/sdk/win-usb.html

Updated the driver in device manager, however enable/disable USB debugging and unplugging/plugging USB still did not work. Finally the "adb kill-server" and "adb start-server" mentioned in other answers did the trick once the driver was updated.

I was facing same issue on Android Studio 2.2 preview 1, solution by @AndresSuarez was correct but for some reasons I couldn't find JAVA TM process in my task manager. So I tried the following solution and it worked -

Open command prompt and type TASKKILL /F /IM java.exe. This will kill all JAVA TM processes automatically. Now re-compile the app again, it will work.

Additionally, you can create a .bat file, add the above code in it and run it every time you face the issue.

As skaffman suggested, JSP 2.0 Tag Files are the bee's knees.

Let's take your simple example.

Put the following in WEB-INF/tags/wrapper.tag

<%@tag description="Simple Wrapper Tag" pageEncoding="UTF-8"%>
<html><body>
  <jsp:doBody/>
</body></html>

Now in your example.jsp page:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:wrapper>
    <h1>Welcome</h1>
</t:wrapper>

That does exactly what you think it does.

So, lets expand upon that to something a bit more general. WEB-INF/tags/genericpage.tag

<%@tag description="Overall Page template" pageEncoding="UTF-8"%>
<%@attribute name="header" fragment="true" %>
<%@attribute name="footer" fragment="true" %>
<html>
  <body>
    <div id="pageheader">
      <jsp:invoke fragment="header"/>
    </div>
    <div id="body">
      <jsp:doBody/>
    </div>
    <div id="pagefooter">
      <jsp:invoke fragment="footer"/>
    </div>
  </body>
</html>

To use this:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:genericpage>
    <jsp:attribute name="header">
      <h1>Welcome</h1>
    </jsp:attribute>
    <jsp:attribute name="footer">
      <p id="copyright">Copyright 1927, Future Bits When There Be Bits Inc.</p>
    </jsp:attribute>
    <jsp:body>
        <p>Hi I'm the heart of the message</p>
    </jsp:body>
</t:genericpage>

What does that buy you? A lot really, but it gets even better...

WEB-INF/tags/userpage.tag

<%@tag description="User Page template" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>
<%@attribute name="userName" required="true"%>

<t:genericpage>
    <jsp:attribute name="header">
      <h1>Welcome ${userName}</h1>
    </jsp:attribute>
    <jsp:attribute name="footer">
      <p id="copyright">Copyright 1927, Future Bits When There Be Bits Inc.</p>
    </jsp:attribute>
    <jsp:body>
        <jsp:doBody/>
    </jsp:body>
</t:genericpage>

To use this: (assume we have a user variable in the request)

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:userpage userName="${user.fullName}">
  <p>
    First Name: ${user.firstName} <br/>
    Last Name: ${user.lastName} <br/>
    Phone: ${user.phone}<br/>
  </p>
</t:userpage>

But it turns you like to use that user detail block in other places. So, we'll refactor it. WEB-INF/tags/userdetail.tag

<%@tag description="User Page template" pageEncoding="UTF-8"%>
<%@tag import="com.example.User" %>
<%@attribute name="user" required="true" type="com.example.User"%>

First Name: ${user.firstName} <br/>
Last Name: ${user.lastName} <br/>
Phone: ${user.phone}<br/>

Now the previous example becomes:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>

<t:userpage userName="${user.fullName}">
  <p>
    <t:userdetail user="${user}"/>
  </p>
</t:userpage>

The beauty of JSP Tag files is that it lets you basically tag generic markup and then refactor it to your heart's content.

JSP Tag Files have pretty much usurped things like Tiles etc., at least for me. I find them much easier to use as the only structure is what you give it, nothing preconceived. Plus you can use JSP tag files for other things (like the user detail fragment above).

Here's an example that is similar to DisplayTag that I've done, but this is all done with Tag Files (and the Stripes framework, that's the s: tags..). This results in a table of rows, alternating colors, page navigation, etc:

<t:table items="${actionBean.customerList}" var="obj" css_class="display">
  <t:col css_class="checkboxcol">
    <s:checkbox name="customerIds" value="${obj.customerId}"
                onclick="handleCheckboxRangeSelection(this, event);"/>
  </t:col>
  <t:col name="customerId" title="ID"/>
  <t:col name="firstName" title="First Name"/>
  <t:col name="lastName" title="Last Name"/>
  <t:col>
    <s:link href="/Customer.action" event="preEdit">
      Edit
      <s:param name="customer.customerId" value="${obj.customerId}"/>
      <s:param name="page" value="${actionBean.page}"/>
    </s:link>
  </t:col>
</t:table>

Of course the tags work with the JSTL tags (like c:if, etc.). The only thing you can't do within the body of a tag file tag is add Java scriptlet code, but this isn't as much of a limitation as you might think. If I need scriptlet stuff, I just put the logic in to a tag and drop the tag in. Easy.

So, tag files can be pretty much whatever you want them to be. At the most basic level, it's simple cut and paste refactoring. Grab a chunk of layout, cut it out, do some simple parameterization, and replace it with a tag invocation.

At a higher level, you can do sophisticated things like this table tag I have here.

shell_exec returns all of the output stream as a string. exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter.

See

• http://php.net/manual/en/function.shell-exec.php
• http://php.net/manual/en/function.exec.php

I'll chip in my solution, since i can't find anything like this in the answers so far. It is a bit overengineered maybe, but it generates the lookup table using C++14 std::index_sequence in compile time.

#include <array>
#include <utility>

constexpr unsigned long reverse(uint8_t value) {
    uint8_t result = 0;
    for (std::size_t i = 0, j = 7; i < 8; ++i, --j) {
        result |= ((value & (1 << j)) >> j) << i;
    }
    return result;
}

template<size_t... I>
constexpr auto make_lookup_table(std::index_sequence<I...>)
{
    return std::array<uint8_t, sizeof...(I)>{reverse(I)...};   
}

template<typename Indices = std::make_index_sequence<256>>
constexpr auto bit_reverse_lookup_table()
{
    return make_lookup_table(Indices{});
}

constexpr auto lookup = bit_reverse_lookup_table();

int main(int argc)
{
    return lookup[argc];
}

Tried to use the solution proposed by Misko, but in my situation, some attributes, which needed to be merged into my template html, were themselves directives.

Unfortunately, not all of the directives referenced by the resulting template did work correctly. I did not have enough time to dive into angular code and find out the root cause, but found a workaround, which could potentially be helpful.

The solution was to move the code, which creates the template html, from compile to a template function. Example based on code from above:

    angular.module('formComponents', [])
  .directive('formInput', function() {
    return {
        restrict: 'E',
        template: function(element, attrs) {
           var type = attrs.type || 'text';
            var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
            var htmlText = '<div class="control-group">' +
                '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                    '<div class="controls">' +
                    '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                    '</div>' +
                '</div>';
             return htmlText;
        }
        compile: function(element, attrs)
        {
           //do whatever else is necessary
        }
    }
})

I do this, which will handle 1=TRUE=yes=YES=true, 0=FALSE=no=NO=false:

BOOL=false
if (STRING)
  BOOL=JSON.parse(STRING.toLowerCase().replace('no','false').replace('yes','true'));

Replace STRING with the name of your string variable.

If it's not null, a numerical value or one of these strings: "true", "TRUE", "false", "FALSE", "yes", "YES", "no", "NO" It will throw an error (intentionally.)

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

[How can I] Change the password, so I can share it with others and let them sign

Using keytool:

Re-enter new keystore password:  new-password

For the most part you treat it as if you are validating any other kind of control but use the InitialValue property of the required field validator.

<asp:RequiredFieldValidator ID="rfv1" runat="server" ControlToValidate="your-dropdownlist" InitialValue="Please select" ErrorMessage="Please select something" />

Basically what it's saying is that validation will succeed if any other value than the 1 set in InitialValue is selected in the dropdownlist.

If databinding you will need to insert the "Please select" value afterwards as follows

this.ddl1.Items.Insert(0, "Please select");

Well, for me this is the expected result; adding six months to Jan. 1st July.

Modern Solution

The result is that the circle never gets distorted and the text stays exactly in the middle of the circle - vertically and horizontally.

.circle {
  background: gold;
  width: 40px; 
  height: 40px;
  border-radius: 50%;
  display: flex; /* or inline-flex */
  align-items: center; 
  justify-content: center;
}

<div class="circle">text</div>

Simple and easy to use. Enjoy!

make sure you are on a branch, at least in master branch

type:

git branch

you should see:

ubuntu-user:~/git/turmeric-releng$ git branch

* (no branch)
master

then type:

git checkout master

then all your changes will fit in master branch (or the branch u choose)

df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])

type(df.<column name>)

example: if you want to convert day which is initially a string to a Timestamp in Pandas

df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])

type(df.day)

The output will be pandas.tslib.Timestamp

Stacks for threads are often smaller. You can change the default at link time, or change at run time also. For reference, some defaults are:

• glibc i386, x86_64: 7.4 MB
• Tru64 5.1: 5.2 MB
• Cygwin: 1.8 MB
• Solaris 7..10: 1 MB
• MacOS X 10.5: 460 KB
• AIX 5: 98 KB
• OpenBSD 4.0: 64 KB
• HP-UX 11: 16 KB

You can use typeof(N) to get the actual object type, but what you want to do is check the tag, not the type of the DOM element.

In that case, use the elem.tagName or elem.nodeName property.

if you want to get really creative, you can use a dictionary of tagnames and anonymous closures instead if a switch or if/else.

Place the image in a source folder, not a regular folder. That is: right-click on project -> New -> Source Folder. Place the image in that source folder. Then:

InputStream input = classLoader.getResourceAsStream("image.jpg");

Note that the path is omitted. That's because the image is directly in the root of the path. You can add folders under your source folder to break it down further if you like. Or you can put the image under your existing source folder (usually called src).

Refreshing db context with Reload is not recommended way due to performance loses. It is good enough and the best practice to initialize a new instance of the dbcontext before each operation executed. It also provide you a refreshed up to date context for each operation.

using (YourContext ctx = new YourContext())
{
   //Your operations
}

You can use the below syntax -

Use the INFORMATION_SCHEMA.TABLES view to get the list of tables. Generate Drop scripts in the select statement and drop it using Dynamic SQL:

DECLARE @sql NVARCHAR(max)=''

SELECT @sql += ' Drop table ' + QUOTENAME(TABLE_SCHEMA) + '.'+ QUOTENAME(TABLE_NAME) + '; '
FROM   INFORMATION_SCHEMA.TABLES
WHERE  TABLE_TYPE = 'BASE TABLE'

Exec Sp_executesql @sql

Sys.Tables Version

DECLARE @sql NVARCHAR(max)=''

SELECT @sql += ' Drop table ' + QUOTENAME(s.NAME) + '.' + QUOTENAME(t.NAME) + '; '
FROM   sys.tables t
       JOIN sys.schemas s
         ON t.[schema_id] = s.[schema_id]
WHERE  t.type = 'U'

Exec sp_executesql @sql

Note: If you have any foreign Keys defined between tables then first run the below query to disable all foreign keys present in your database.

EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"

Note that this information is readily available in the documentation; just press F1. The page you link to deals with Visual Basic .NET, not VBA. While (no pun intended) there is some degree of overlap in syntax between VBA and VB.NET, one can't just assume that the documentation for the one can be applied directly to the other.

Also in the VBA help file:

Tip The Do...Loop statement provides a more structured and flexible way to perform looping.

You have some data that is being entered by users somewhere in the application.

1. the component in which the data is being entered should have this data in its state because it needs to manipulate and change it during data entry

2. anywhere else in the application the data should be passed down as props to all the other components

So yes the props are changing but they are changed at the 'source' and will then simply flow down from there. So props are immutable in the context of the component receiving them.

E.g. a reference data screen where users edit a list of suppliers would manage this in state, which would then have an action cause the updated data to be saved in ReferenceDataState which could be one level below AppState and then this supplier list would be passed as props to all the components that needed to use it.

All the answers work but they always traverse the whole list. If I understand your question, you only need the first match. So you don't have to consider the rest of the list if you found your first match:

mylist = ['abc123', 'def456', 'ghi789']
sub = 'abc'
next((s for s in mylist if sub in s), None) # returns 'abc123'

If the match is at the end of the list or for very small lists, it doesn't make a difference, but consider this example:

import timeit

mylist = ['abc123'] + ['xyz123']*1000
sub = 'abc'

timeit.timeit('[s for s in mylist if sub in s]', setup='from __main__ import mylist, sub', number=100000)
# for me 7.949463844299316 with Python 2.7, 8.568840944994008 with Python 3.4
timeit.timeit('next((s for s in mylist if sub in s), None)', setup='from __main__ import mylist, sub', number=100000) 
# for me 0.12696599960327148 with Python 2.7, 0.09955992100003641 with Python 3.4

When I have used replace all 0 and match case with blank in Excel 2010 I find it paints the cell blank but the data is just whitewashed. So you use counta and the cell is still counted as with something to count. Never use that method in 2010 unless it is for display purposes only.

Use the Index property in your DGV's SelectedRows collection:

int index = yourDGV.SelectedRows[0].Index;

According to gurus, I define LINQ as motorcycle and SP as car. If you want to go for a short trip and only have small passengers(in this case 2), go gracefully with LINQ. But if you want to go for a journey and have large band, i think you should choose SP.

As a conclusion, choosing between motorcycle or car is depend on your route (business), length (time), and passengers (data).

Hope it helps, I may be wrong. :D

Use

 mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 mediaplayer.prepareAsync();
 mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mp) {
          mediaplayer.start();
      }
 });

It specifies that an iterator has come to an end. You can think of yield break as a return statement which does not return a value.

For example, if you define a function as an iterator, the body of the function may look like this:

for (int i = 0; i < 5; i++)
{
    yield return i;
}

Console.Out.WriteLine("You will see me");

Note that after the loop has completed all its cycles, the last line gets executed and you will see the message in your console app.

Or like this with yield break:

int i = 0;
while (true)
{
    if (i < 5)
    {
        yield return i;
    }
    else
    {
        // note that i++ will not be executed after this
        yield break;
    }
    i++;
}

Console.Out.WriteLine("Won't see me");

In this case the last statement is never executed because we left the function early.

The ES6 way to split a string into an array character-wise is by using the spread operator. It is simple and nice.

array = [...myString];

Example:

let myString = "Hello world!"
array = [...myString];
console.log(array);

// another example:

console.log([..."another splitted text"]);

This is a CSS trick, not a formal solution. I leave the code with the period black because it helps me position the element. Afterward, color your content (color:white) and (margin-top:-5px or so) to make it as though the period is not there.

div.yourdivname:after {
content: ".";
  border-bottom:1px solid grey;
  width:60%;
  display:block;
  margin:0 auto;
}

This is very helpful since that API's will change for sure and you can refactor once and very fast!

This past week I installed Microsoft SQL Server 2014 Developer Edition on my dev box, and immediately ran into a problem I had never seen before.

I’ve installed various versions of SQL Server countless times, and it is usually a painless procedure. Install the server, run the Management Console, it’s that simple. However, after completing this installation, when I tried to log in to the server using SSMS, I got an error like the one below:

SQL Server login error 18456 “Login failed for user… (Microsoft SQL Server, Error: 18456)” I’m used to seeing this error if I typed the wrong password when logging in – but that’s only if I’m using mixed mode (Windows and SQL Authentication). In this case, the server was set up with Windows Authentication only, and the user account was my own. I’m still not sure why it didn’t add my user to the SYSADMIN role during setup; perhaps I missed a step and forgot to add it. At any rate, not all hope was lost.

The way to fix this, if you cannot log on with any other account to SQL Server, is to add your network login through a command line interface. For this to work, you need to be an Administrator on Windows for the PC that you’re logged onto.

Stop the MSSQL service. Open a Command Prompt using Run As Administrator. Change to the folder that holds the SQL Server EXE file; the default for SQL Server 2014 is “C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Binn”. Run the following command: “sqlservr.exe –m”. This will start SQL Server in single-user mode. While leaving this Command Prompt open, open another one, repeating steps 2 and 3. In the second Command Prompt window, run “SQLCMD –S Server_Name\Instance_Name” In this window, run the following lines, pressing Enter after each one: 1

CREATE LOGIN [domainName\loginName] FROM WINDOWS 2 GO 3 SP_ADDSRVROLEMEMBER 'LOGIN_NAME','SYSADMIN' 4 GO Use CTRL+C to end both processes in the Command Prompt windows; you will be prompted to press Y to end the SQL Server process.

Restart the MSSQL service. That’s it! You should now be able to log in using your network login.

I had the exact same problem you describe above (Galaxy Nexus on t-mobile USA) it is because mobile data is turned off.

In Jelly Bean it is: Settings > Data Usage > mobile data

Note that I have to have mobile data turned on PRIOR to sending an MMS OR receiving one. If I receive an MMS with mobile data turned off, I will get the notification of a new message and I will receive the message with a download button. But if I do not have mobile data on prior, the incoming MMS attachment will not be received. Even if I turn it on after the message was received.

For some reason when your phone provider enables you with the ability to send and receive MMS you must have the Mobile Data enabled, even if you are using Wifi, if the Mobile Data is enabled you will be able to receive and send MMS, even if Wifi is showing as your internet on your device.

It is a real pain, as if you do not have it on, the message can hang a lot, even when turning on Mobile Data, and might require a reboot of the device.

All given answers work fine, but I remember learning that using setAlpha can be a bad idea performance wise (more info here). So creating a StateListDrawable is a better idea to manage disabled state of buttons. Here's how:

Create a XML btn_blue.xml in res/drawable folder:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Disable background -->
    <item android:state_enabled="false"
          android:color="@color/md_blue_200"/>
    
    <!-- Enabled background -->
    <item android:color="@color/md_blue_500"/>
</selector>

Create a button style in res/values/styles.xml

<style name="BlueButton" parent="ThemeOverlay.AppCompat">
      <item name="colorButtonNormal">@drawable/btn_blue</item>
      <item name="android:textColor">@color/md_white_1000</item>
</style>

Then apply this style to your button:

<Button
     android:id="@+id/my_disabled_button"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:theme="@style/BlueButton"/>

Now when you call btnBlue.setEnabled(true) OR btnBlue.setEnabled(false) the state colors will automatically switch.

FOR ANYONE RUNNING AN OS WITH SELINUX: The correct way of allowing httpd to write to the laravel storage folder is:

sudo semanage fcontext -a -t httpd_sys_rw_content_t '/path/to/www/storage(/.*)?'

Then to apply the changes immediately:

sudo restorecon -F -r '/path/to/www/storage'

SELinux can be a pain to deal with, but if it's present then I'd STRONGLY ADVISE you learn it rather than bypassing it entirely.

Have you seen this already? The cause seems to be a very old libpam on one of the sides, probably on that customer.

Or the links for the version might be missing : http://www.linux.org/docs/ldp/howto/Program-Library-HOWTO/shared-libraries.html

use the following way to convert the array to an object easily.

var obj = {};
array.forEach(function(e){
   obj[e[0]] = e[1]
})

This will use the first element as the key and the second element as the value for each element.

I came across a wonderful piece of code to check whether or not an element is a child of another element. I have to use this because IE doesn't support the .contains element method. Hope this will help others as well.

Below is the function:

function isChildOf(childObject, containerObject) {
  var returnValue = false;
  var currentObject;

  if (typeof containerObject === 'string') {
    containerObject = document.getElementById(containerObject);
  }
  if (typeof childObject === 'string') {
    childObject = document.getElementById(childObject);
  }

  currentObject = childObject.parentNode;

  while (currentObject !== undefined) {
    if (currentObject === document.body) {
      break;
    }

    if (currentObject.id == containerObject.id) {
      returnValue = true;
      break;
    }

    // Move up the hierarchy
    currentObject = currentObject.parentNode;
  }

  return returnValue;
}

Best way I have used is to mount the VS 2010 Image or insert the Installation disc and run the uninstall option, really works well

I would make the class final and every method would be static.

So the class cannot be extended and the methods can be called by Classname.methodName. If you add members, be sure that they work thread safe ;)

In the default constructor (and any non-default ones if you have any too of course):

public foo() {
    Bar = "bar";
}

This is no less performant that your original code I believe, since this is what happens behind the scenes anyway.

My solution is to cover all the range of diacritics:

([A-z0-9À-ž\s]){2,}

A-z - this is for all latin characters

0-9 - this is for all digits

À-ž - this is for all diacritics

\s - this is for spaces

{2,} - string needs to be at least 2 characters long

Self invoking anonymous function (SIAF)

Self-invoking functions runs instantly, even if DOM isn't completely ready.

jQuery document.ready vs self calling anonymous function

There are multiple methods for handling this problem.

My advice is to use the powerful Windows freeware console application SendEmail.

sendEmail.exe -f [email protected] -o message-file=body.txt -u subject message -t [email protected] -a attachment.zip -s smtp.gmail.com:446 -xu gmail.login -xp gmail.password

From git stash --help

Recovering stashes that were cleared/dropped erroneously
   If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
   following incantation to get a list of stashes that are still in your repository, but not reachable any more:

       git fsck --unreachable |
       grep commit | cut -d\  -f3 |
       xargs git log --merges --no-walk --grep=WIP

This helped me better than the accepted answer with the same scenario.

Your JavaScript is fine, unless you have other scripts running on this page which may corrupt everything. You may check this using Firebug.

I've now tested a bit and it really seems that ASP.net ignores disabled controls. Basically the postback is issued, but probably the framework ignores such events since it "assumes" that a disabled button cannot raise any postback and so it ignores possibly attached handlers. Now this is just my personal reasoning, one could use Reflector to check this in more depth.

As a solution you could really try to do the disabling at a later point, basically you delay the control.disabled = "disabled" call using a JavaTimer or some other functionality. In this way 1st the postback to the server is issued before the control is being disabled by the JavaScript function. Didn't test this but it could work

The align-items property of flex-box aligns the items inside a flex container along the cross axis just like justify-content does along the main axis. (For the default flex-direction: row the cross axis corresponds to vertical and the main axis corresponds to horizontal. With flex-direction: column those two are interchanged respectively).

Here's an example of how align-items:center looks:

But align-content is for multi line flexible boxes. It has no effect when items are in a single line. It aligns the whole structure according to its value. Here's an example for align-content: space-around;:

And here's how align-content: space-around; with align-items:center looks:

Note the 3rd box and all other boxes in first line change to vertically centered in that line.

Here are some codepen links to play with:

Here's a super cool pen which shows and lets you play with almost everything in flexbox.

This will return specifically what you are asking.

Dim mySiteUrl = Request.Url.Host.ToString()

I know this is an older question. But I needed the same simple answer and this returns exactly what is asked (without the http://).

git branch newbranch
git checkout master 
git merge newbranch 

Yes there is.

Proxies may send a HTTP_X_FORWARDED_FOR header but even that is optional.

Also keep in mind that visitors may share IP addresses; University networks, large companies and third-world/low-budget ISPs tend to share IPs over many users.

I also had the similar problem recently with Oracle 12c. It got resolved after I changed the version of the ojdbc jar used. Replaced ojdbc14 with ojdbc6 jar.

Make sure you don't add or uncomment the AllowNoPassword option after the $i++ line.

/* Uncomment the following to enable logging in to passwordless accounts, * after taking note of the associated security risks. */

 $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

JFrame.setVisible(true);

You can either use setVisible(false) or dispose() method to disappear current form.

Create an output file and custom function:

outputFile = open('outputfile.log', 'w')

def printing(text):
    print(text)
    if outputFile:
        outputFile.write(str(text))

Then instead of print(text) in your code, call printing function.

printing("START")
printing(datetime.datetime.now())
printing("COMPLETE")
printing(datetime.datetime.now())

ZShape is not static so it requires an instance of the outer class.

The simplest solution is to make ZShape and any nested class static if you can.

I would also make any fields final or static final that you can as well.

Integer i = theLong != null ? theLong.intValue() : null;

or if you don't need to worry about null:

// auto-unboxing does not go from Long to int directly, so
Integer i = (int) (long) theLong;

And in both situations, you might run into overflows (because a Long can store a wider range than an Integer).

Java 8 has a helper method that checks for overflow (you get an exception in that case):

Integer i = theLong == null ? null : Math.toIntExact(theLong);

1. go to the master branch our-team

   • git checkout our-team

2. pull all the new changes from our-team branch

   • git pull

3. go to your branch featurex

   • git checkout featurex

4. merge the changes of our-team branch into featurex branch

   • git merge our-team
   • or git cherry-pick {commit-hash} if you want to merge specific commits

5. push your changes with the changes of our-team branch

   • git push

Note: probably you will have to fix conflicts after merging our-team branch into featurex branch before pushing

For those looking for an in-transaction solution, the following seems to work.

Instead of an ENUM, a DOMAIN shall be used on type TEXT with a constraint checking that the value is within the specified list of allowed values (as suggested by some comments). The only problem is that no constraint can be added (and thus neither modified) to a domain if it is used by any composite type (the docs merely says this "should eventually be improved"). Such a restriction may be worked around, however, using a constraint calling a function, as follows.

START TRANSACTION;

CREATE FUNCTION test_is_allowed_label(lbl TEXT) RETURNS BOOL AS $function$
    SELECT lbl IN ('one', 'two', 'three');
$function$ LANGUAGE SQL IMMUTABLE;

CREATE DOMAIN test_domain AS TEXT CONSTRAINT val_check CHECK (test_is_allowed_label(value));

CREATE TYPE test_composite AS (num INT, word test_domain);

CREATE TABLE test_table (val test_composite);
INSERT INTO test_table (val) VALUES ((1, 'one')::test_composite), ((3, 'three')::test_composite);
-- INSERT INTO test_table (val) VALUES ((4, 'four')::test_composite); -- restricted by the CHECK constraint

CREATE VIEW test_view AS SELECT * FROM test_table; -- just to show that the views using the type work as expected

CREATE OR REPLACE FUNCTION test_is_allowed_label(lbl TEXT) RETURNS BOOL AS $function$
    SELECT lbl IN ('one', 'two', 'three', 'four');
$function$ LANGUAGE SQL IMMUTABLE;

INSERT INTO test_table (val) VALUES ((4, 'four')::test_composite); -- allowed by the new effective definition of the constraint

SELECT * FROM test_view;

CREATE OR REPLACE FUNCTION test_is_allowed_label(lbl TEXT) RETURNS BOOL AS $function$
    SELECT lbl IN ('one', 'two', 'three');
$function$ LANGUAGE SQL IMMUTABLE;

-- INSERT INTO test_table (val) VALUES ((4, 'four')::test_composite); -- restricted by the CHECK constraint, again

SELECT * FROM test_view; -- note the view lists the restricted value 'four' as no checks are made on existing data

DROP VIEW test_view;
DROP TABLE test_table;
DROP TYPE test_composite;
DROP DOMAIN test_domain;
DROP FUNCTION test_is_allowed_label(TEXT);

COMMIT;

Previously, I used a solution similar to the accepted answer, but it is far from being good once views or functions or composite types (and especially views using other views using the modified ENUMs...) are considered. The solution proposed in this answer seems to work under any conditions.

The only disadvantage is that no checks are performed on existing data when some allowed values are removed (which might be acceptable, especially for this question). (A call to ALTER DOMAIN test_domain VALIDATE CONSTRAINT val_check ends up with the same error as adding a new constraint to the domain used by a composite type, unfortunately.)

Note that a slight modification such as CHECK (value = ANY(get_allowed_values())), where get_allowed_values() function returned the list of allowed values, would not work - which is quite strange, so I hope the solution proposed above works reliably (it does for me, so far...). (it works, actually - it was my error)

To those still having problems, I solved it this way:

List<Item> newItems = databaseHandler.getItems();
ListArrayAdapter.clear();
ListArrayAdapter.addAll(newItems);
ListArrayAdapter.notifyDataSetChanged();
databaseHandler.close();

I first cleared the data from the adapter, then added the new collection of items, and only then set notifyDataSetChanged(); This was not clear for me at first, so I wanted to point this out. Take note that without calling notifyDataSetChanged() the view won't be updated.

If this is something you'll need to do often...then you may want to denormalize the relationship between tables A and B.

For example, on insert to table B, you could write zero or more entries to a juncion table mapping B to A based on partial mapping. Similarly, changes to either table could update this association.

This all depends on how frequently tables A and B are modified. If they are fairly static, then taking a hit on INSERT is less painful then repeated hits on SELECT.

No you can't use bind variables that way. In your second example :into_bind in v_query_str is just a placeholder for value of variable v_num_of_employees. Your select into statement will turn into something like:

SELECT COUNT(*) INTO  FROM emp_...

because the value of v_num_of_employees is null at EXECUTE IMMEDIATE.

Your first example presents the correct way to bind the return value to a variable.

Edit

The original poster has edited the second code block that I'm referring in my answer to use OUT parameter mode for v_num_of_employees instead of the default IN mode. This modification makes the both examples functionally equivalent.

Other answer were not working with a generic interface.

This one does, just replace typeof(ISomeInterface) by typeof (T).

List<string> types = AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes())
            .Where(x => typeof(ISomeInterface).IsAssignableFrom(x) && !x.IsInterface && !x.IsAbstract)
            .Select(x => x.Name).ToList();

So with

AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes())

we get all the assemblies

!x.IsInterface && !x.IsAbstract

is used to exclude the interface and abstract ones and

.Select(x => x.Name).ToList();

to have them in a list.

Non VBA Solution:

Use Conditional Formatting rule with formula: =ISNA(A1) (to highlight cells with all errors - not only #N/A, use =ISERROR(A1))

VBA Solution:

Your code loops through 50 mln cells. To reduce number of cells, I use .SpecialCells(xlCellTypeFormulas, 16) and .SpecialCells(xlCellTypeConstants, 16)to return only cells with errors (note, I'm using If cell.Text = "#N/A" Then)

Sub ColorCells()
    Dim Data As Range, Data2 As Range, cell As Range
    Dim currentsheet As Worksheet

    Set currentsheet = ActiveWorkbook.Sheets("Comparison")

    With currentsheet.Range("A2:AW" & Rows.Count)
        .Interior.Color = xlNone
        On Error Resume Next
        'select only cells with errors
        Set Data = .SpecialCells(xlCellTypeFormulas, 16)
        Set Data2 = .SpecialCells(xlCellTypeConstants, 16)
        On Error GoTo 0
    End With

    If Not Data2 Is Nothing Then
        If Not Data Is Nothing Then
            Set Data = Union(Data, Data2)
        Else
            Set Data = Data2
        End If
    End If

    If Not Data Is Nothing Then
        For Each cell In Data
            If cell.Text = "#N/A" Then
               cell.Interior.ColorIndex = 4
            End If
        Next
    End If
End Sub

Note, to highlight cells witn any error (not only "#N/A"), replace following code

If Not Data Is Nothing Then
   For Each cell In Data
       If cell.Text = "#N/A" Then
          cell.Interior.ColorIndex = 3
       End If
   Next
End If

with

If Not Data Is Nothing Then Data.Interior.ColorIndex = 3

UPD: (how to add CF rule through VBA)

Sub test()
    With ActiveWorkbook.Sheets("Comparison").Range("A2:AW" & Rows.Count).FormatConditions
        .Delete
        .Add Type:=xlExpression, Formula1:="=ISNA(A1)"
        .Item(1).Interior.ColorIndex = 3
    End With
End Sub

For me neither the MouseClick or Click event worked, because the events, simply, are not called when you right click. The quick way to do it is:

 private void button1_MouseUp(object sender, MouseEventArgs e)
 {
        if (e.Button == MouseButtons.Right)
        {
            //do something here
        }
        else//left or middle click
        {
            //do something here
        }
 }

You can modify that to do exactly what you want depended on the arguments' values.

WARNING: There is one catch with only using the mouse up event. if you mousedown on the control and then you move the cursor out of the control to release it, you still get the event fired. In order to avoid that, you should also make sure that the mouse up occurs within the control in the event handler. Checking whether the mouse cursor coordinates are within the control's rectangle before you check the buttons will do it properly.

I have had the same issue in OSX. It can be fixed by running Disk Utilities to Repair Permissions. I agree with Peter Nixey: in my case it is caused when my 3G dongle installs or reinstalls its driver. Repairing Permissions afterward fixes the issue.

Assert.That(myTestDelegate, Throws.ArgumentException
    .With.Property("Message").EqualTo("your argument is invalid."));

You need a click listener which calls addActivityItem if less than 2 options exist:

var activities = document.getElementById("activitySelector");

activities.addEventListener("click", function() {
    var options = activities.querySelectorAll("option");
    var count = options.length;
    if(typeof(count) === "undefined" || count < 2)
    {
        addActivityItem();
    }
});

activities.addEventListener("change", function() {
    if(activities.value == "addNew")
    {
        addActivityItem();
    }
});

function addActivityItem() {
    // ... Code to add item here
}

A live demo is here on JSfiddle.

from terminal

 > cd myProjectPath
 myProjectPath > npm install

I'd just like to add that one small issue with outputting the buffer strings from a spawned process with console.log() is that it adds newlines, which can spread your spawned process output over additional lines. If you output stdout or stderr with process.stdout.write() instead of console.log(), then you'll get the console output from the spawned process 'as is'.

I saw that solution here: Node.js: printing to console without a trailing newline?

Hope that helps someone using the solution above (which is a great one for live output, even if it is from the documentation).

This example of a Javascript function is called by an event listener to identify the form

function submitUpdate(event) {
    trigger_field = document.getElementById(event.target.id);
    trigger_form = trigger_field.form;

Here is the function I am using for my work

function getLatLngByZipcode(zipcode) 
{
    var geocoder = new google.maps.Geocoder();
    var address = zipcode;
    geocoder.geocode({ 'address': address }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var latitude = results[0].geometry.location.lat();
            var longitude = results[0].geometry.location.lng();
            alert("Latitude: " + latitude + "\nLongitude: " + longitude);
        } else {
            alert("Request failed.")
        }
    });
    return [latitude, longitude];
}

If you are saying you wanna pass javascript value from one jsp to another in javascript then use URLRewriting technique to pass javascript variable to next jsp file and access that in next jsp in request object.

Other wise you can't do it.

For raw speed, use C. For power, use C++. For .NET compatibility, use C#.

They're all pretty complex as languages go; C through decades of gradual accretion, C++ through years of more rapid enhancement, and C# through the power of Microsoft.

Or, if you are looking for simple collection of errors for your apps.. here is my implementation of this:

public override void OnActionExecuting(HttpActionContext actionContext)
    {
        var modelState = actionContext.ModelState;

        if (!modelState.IsValid) 
        {

            var errors = new List<string>();
            foreach (var state in modelState)
            {
                foreach (var error in state.Value.Errors)
                {
                    errors.Add(error.ErrorMessage);
                }
            }

            var response = new { errors = errors };

            actionContext.Response = actionContext.Request
                .CreateResponse(HttpStatusCode.BadRequest, response, JsonMediaTypeFormatter.DefaultMediaType);

The solution by "Mark Seagoe" worked for me too. I got a message that "Port 443 in use by Unable to open process with PID 14508". So i opened task manager and killed this process 14508. This was used by my previous xampp version and it was orphaned.

so no need to change any ports or anything, this is a simple two step process and it worked .

You actually do the normal delete. But on the model you specify that its a softdelete model.

So on your model add the code:

class Contents extends Eloquent {

    use SoftDeletingTrait;

    protected $dates = ['deleted_at'];

}

Then on your code do the normal delete like:

$id = Contents::find( $id );
$id ->delete();

Also make sure you have the deleted_at column on your table.

Or just see the docs: http://laravel.com/docs/eloquent#soft-deleting

I have been researching this for quite a while and I am trying to do the same thing, so hopefully this will help someone else. I have been using crossbrowsertesting.com and literally testing this in almost every browser known to man. The solution I've got currently works in Opera, Chrome, Firefox 3.5+, IE8+, iPhone 3GS, iPhone 4, iPhone 4s, iPhone 5, iPhone 5s, iPad 1+, Android 2.3+, Windows Phone 8.

Dynamically Changing Sources

Dynamically changing the video is very difficult, and if you want a Flash fallback you will have to remove the video from the DOM/page and re-add it so that Flash will update because Flash will not recognize dynamic updates to Flash vars. If you're going to use JavaScript to change it dynamically, I would completely remove all <source> elements and just use canPlayType to set the src in JavaScript and break or return after the first supported video type and don't forget to dynamically update the flash var mp4. Also, some browsers won't register that you changed the source unless you call video.load(). I believe the issue with .load() you were experiencing can be fixed by first calling video.pause(). Removing and adding video elements can slow down the browser because it continues buffering the removed video, but there's a workaround.

Cross-browser Support

As far as the actual cross-browser portion, I arrived at Video For Everybody as well. I already tried the MediaelementJS Wordpress plugin, which turned out to cause a lot more issues than it resolved. I suspect the issues were due to the Wordpress plug-in and not the actually library. I'm trying to find something that works without JavaScript, if possible. So far, what I've come up with is this plain HTML:

</object>
<strong>Download video:</strong>  <a href="video.mp4">MP4 format</a> | <a href="video.ogv">Ogg format</a> | <a href="video.webm">WebM format</a>
</video>

Important notes:

• Ended up putting the ogg as the first <source> because Mac OS Firefox quits trying to play the video if it encounters an MP4 as the first <source>.
• The correct MIME types are important .ogv files should be video/ogg, not video/ogv
• If you have HD video, the best transcoder I've found for HD quality OGG files is Firefogg
• The .iphone.mp4 file is for iPhone 4+ which will only play videos that are MPEG-4 with H.264 Baseline 3 Video and AAC audio. The best transcoder I found for that format is Handbrake, using the iPhone & iPod Touch preset will work on iPhone 4+, but to get iPhone 3GS to work you need to use the iPod preset which has much lower resolution which I added as video.iphone3g.mp4.
• In the future we will be able to use a media attribute on the <source> elements to target mobile devices with media queries, but right now the older Apple and Android devices don't support it well enough.

Edit:

• I'm still using Video For Everybody but now I've transitioned to using FlowPlayer, to control the Flash fallback, which has an awesome JavaScript API that can be used to control it.

In the properties for your pydev project, there's a pane called "PyDev - PYTHONPATH", with a sub-pane called "External Libraries". You can add source folders (any folder that has an __init__.py) to the path using that pane. Your project code will then be able to import modules from those source folders.

Yes.

<head>
<script type='javascript'>
var x = 0;
</script>
</head>
<body>
  <input type='button' onclick='x++;'/>
</body>

[Psuedo code, god I hope this is right.]

In addition to everything else that has been said, you can call DefaultIfEmpty() before you call Single(). This will ensure that your sequence contains something and thereby averts the InvalidOperationException "Sequence contains no elements". For example:

BlogPost post = (from p in dc.BlogPosts
                 where p.BlogPostID == ID
                 select p).DefaultIfEmpty().Single();

Solution for PHP 5.2 with DateTime objects. But startDate MUST be before endDate.

function createRange($startDate, $endDate) {
    $tmpDate = new DateTime($startDate);
    $tmpEndDate = new DateTime($endDate);

    $outArray = array();
    do {
        $outArray[] = $tmpDate->format('Y-m-d');
    } while ($tmpDate->modify('+1 day') <= $tmpEndDate);

    return $outArray;
}

Using:

$dates = createRange('2010-10-01', '2010-10-05');

$dates contain:

Array( '2010-10-01', '2010-10-02', '2010-10-03', '2010-10-04', '2010-10-05' )       

There are 2 main kinds of transactions; connection transactions and ambient transactions. A connection transaction (such as SqlTransaction) is tied directly to the db connection (such as SqlConnection), which means that you have to keep passing the connection around - OK in some cases, but doesn't allow "create/use/release" usage, and doesn't allow cross-db work. An example (formatted for space):

using (IDbTransaction tran = conn.BeginTransaction()) {
    try {
        // your code
        tran.Commit();
    }  catch {
        tran.Rollback();
        throw;
    }
}

Not too messy, but limited to our connection "conn". If we want to call out to different methods, we now need to pass "conn" around.

The alternative is an ambient transaction; new in .NET 2.0, the TransactionScope object (System.Transactions.dll) allows use over a range of operations (suitable providers will automatically enlist in the ambient transaction). This makes it easy to retro-fit into existing (non-transactional) code, and to talk to multiple providers (although DTC will get involved if you talk to more than one).

For example:

using(TransactionScope tran = new TransactionScope()) {
    CallAMethodThatDoesSomeWork();
    CallAMethodThatDoesSomeMoreWork();
    tran.Complete();
}

Note here that the two methods can handle their own connections (open/use/close/dispose), yet they will silently become part of the ambient transaction without us having to pass anything in.

If your code errors, Dispose() will be called without Complete(), so it will be rolled back. The expected nesting etc is supported, although you can't roll-back an inner transaction yet complete the outer transaction: if anybody is unhappy, the transaction is aborted.

The other advantage of TransactionScope is that it isn't tied just to databases; any transaction-aware provider can use it. WCF, for example. Or there are even some TransactionScope-compatible object models around (i.e. .NET classes with rollback capability - perhaps easier than a memento, although I've never used this approach myself).

All in all, a very, very useful object.

Some caveats:

• On SQL Server 2000, a TransactionScope will go to DTC immediately; this is fixed in SQL Server 2005 and above, it can use the LTM (much less overhead) until you talk to 2 sources etc, when it is elevated to DTC.
• There is a glitch that means you might need to tweak your connection string

None/Null is a data type of the class NoneType in pyspark/python so, Below will not work as you are trying to compare NoneType object with string object

df[df.dt_mvmt == None].count() 0 df[df.dt_mvmt != None].count() 0

correct

df=df.where(col("dt_mvmt").isNotNull()) returns all records with dt_mvmt as None/Null

This my variant of the solution based on LINQ and the Descendants method of the XDocument class

using System;
using System.Linq;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XDocument xml = XDocument.Parse(@"
        <root>
          <child id='1'/>
          <child id='2'>
            <subChild id='3'>
                <extChild id='5' />
                <extChild id='6' />
            </subChild>
            <subChild id='4'>
                <extChild id='7' />
            </subChild>
          </child>
        </root>");

        xml.Descendants().Where(p => p.Name.LocalName == "extChild")
                         .ToList()
                         .ForEach(e => Console.WriteLine(e));

        Console.ReadLine();
    }
}

Results:

Simple answer would be: Null is for Database tables while Blank is for Django Forms.

if re.match(regex, content):

You could also use re.search depending on how you want it to match.

This will write the time & date every 20 seconds in the file ping_ip.txt. The second to last line just says run the same batch file again, and agan, and again,..........etc.

Does not seem to create multiple instances, so that's a good thing.

@echo %time% %date% >>ping_ip.txt
ping -n 20 -w 3 127.0.0.1 >>ping_ip.txt

Just set the img css to be display:inline or display:inline-block

Cellspacing is all around the cell and cannot be changed (i.e. if it's set to one, there will be 1 pixel of space on all sides). Padding can be specified discreetly (e.g. padding-top, padding-bottom, padding-left, and padding-right; or padding: [top] [right] [bottom] [left];).

"Not equals" can be expressed with the "not" operator ! and the standard .equals.

if (a.equals(b)) // a equals b
if (!a.equals(b)) // a not equal to b

Refer to Section 8.3 of this SAML core pdf of oasis SAML specification.

SP and IdP usually communicate each other about a subject. That subject should be identified through a NAME-IDentifier , which should be in some format so that It is easy for the other party to identify it based on the Format.

All these

1.urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified [default]

2.urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

3.urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

4.urn:oasis:names:tc:SAML:2.0:nameid-format:transient

are format for the Name Identifiers.

The name format for a transient ID in SAML 1 is urn:mace:shibboleth:1.0:nameIdentifier and in SAML 2 is urn:oasis:names:tc:SAML:2.0:nameid-format:transient

Transient is for [section 8.3.8 of SAML Core]

Indicates that the content of the element is an identifier with transient semantics and SHOULD be treated as an opaque and temporary value by the relying party.

Unspecified can be used and it purely depends on the entities implementation on their own wish.

The session is stored server-side so you cannot add values to it from JavaScript. All that you get client-side is the session cookie which contains an id. One possibility would be to send an AJAX request to a server-side script which would set the session variable. Example with jQuery's .post() method:

$.post('/setsessionvariable.php', { name: 'value' });

You should, of course, be cautious about exposing such script.

argmax() will only return the first occurrence for each row. http://docs.scipy.org/doc/numpy/reference/generated/numpy.argmax.html

If you ever need to do this for a shaped array, this works better than unravel:

import numpy as np
a = np.array([[1,2,3], [4,3,1]])  # Can be of any shape
indices = np.where(a == a.max())

You can also change your conditions:

indices = np.where(a >= 1.5)

The above gives you results in the form that you asked for. Alternatively, you can convert to a list of x,y coordinates by:

x_y_coords =  zip(indices[0], indices[1])

I'm not sure what problem you are solving, but when I have two side by side containers that need to be the same height, I run a little javascript on page load that finds the maximum height of the two and explicitly sets the other to the same height. It seems to me that height: 100% might just mean "make it the size needed to fully contain the content" when what you really want is "make both the size of the largest content."

Note: you'll need to resize them again if anything happens on the page to change their height -- like a validation summary being made visible or a collapsible menu opening.

Personally, for me, the best solution for a similar issue was:

HTML

<input type="radio" name="selectAll" value="true" />
<input type="radio" name="selectAll" value="false" />

JQuery

var $selectAll = $( "input:radio[name=selectAll]" );
    $selectAll.on( "change", function() {
         console.log( "selectAll: " + $(this).val() );
         // or
         alert( "selectAll: " + $(this).val() );
    });

*The event "click" can work in place of "change" as well.

Hope this helps!

Thanks for the above codes! - I tried several options and this was the ticket. I had problems in that preventDefault was preventing scrolling on the ipad - I am now testing for draggable items and it works great so far.

if (event.target.id == 'draggable_item' ) {
    event.preventDefault();
}

I use this line for Spring Boot applications:

logging.level.org.springframework.jdbc.core = TRACE

This approach pretty universal and I usually use it for any other classes inside my application.

First, it violates two principles of Zen of Python:

• Explicit is better than implicit
• Errors should never pass silently

What it means, is that you intentionally make your error pass silently. Moreover, you don't event know, which error exactly occurred, because except: pass will catch any exception.

Second, if we try to abstract away from the Zen of Python, and speak in term of just sanity, you should know, that using except:pass leaves you with no knowledge and control in your system. The rule of thumb is to raise an exception, if error happens, and take appropriate actions. If you don't know in advance, what actions these should be, at least log the error somewhere (and better re-raise the exception):

try:
    something
except:
    logger.exception('Something happened')

But, usually, if you try to catch any exception, you are probably doing something wrong!

I solved the problem by using the Rnd() function:

Function RollD6() As UInteger
        RollD6 = (Math.Floor(6 * Rnd())) + 1
        Return RollD6
End Function

When the form loads, I use the Randomize() method to make sure I don't always get the same sequence of random numbers from run to run.

speaking of which ...
python3.6 comes with f-strings which makes things much easier in formatting!
now if your python version is greater than 3.6 you can format your strings with these available methods:

name = "python"

print ("i code with %s" %name)          # with help of older method
print ("i code with {0}".format(name))  # with help of format
print (f"i code with {name}")           # with help of f-strings

I had the same problem. I was very new to iPhone development and it was my first time trying to submit my app to App-store...

Check the following :

1. Check that your current "Bundle Identifier" is same as your current "Provisioning Profile" name in "Code Signing Identity".

2. In "Code Signing identity block" - Check Debug AND Distribution have the same "Code Signing Information". Try to keep the "Code Signing Information" same in all the Blocks.

3. Try to Download the "Provisioning Profile" again and double click on the profile. Then use that newly downloaded profile in your "Code Signing Identity".

4. Try to Download the "Certificate" again from the "developer.apple.com" and double click on the certificate. (It worked in my case)

Then "Clean" the project and click on "Build for Archive". Hope your code will be archived perfectly.

From the horse's mouth: Explicit line joining

Two or more physical lines may be joined into logical lines using backslash characters (\), as follows: when a physical line ends in a backslash that is not part of a string literal or comment, it is joined with the following forming a single logical line, deleting the backslash and the following end-of-line character. For example:

if 1900 < year < 2100 and 1 <= month <= 12 \
   and 1 <= day <= 31 and 0 <= hour < 24 \
   and 0 <= minute < 60 and 0 <= second < 60:   # Looks like a valid date
        return 1

A line ending in a backslash cannot carry a comment. A backslash does not continue a comment. A backslash does not continue a token except for string literals (i.e., tokens other than string literals cannot be split across physical lines using a backslash). A backslash is illegal elsewhere on a line outside a string literal.

The legend titles can be labeled by specific aesthetic.

This can be achieved using the guides() or labs() functions from ggplot2 (more here and here). It allows you to add guide/legend properties using the aesthetic mapping.

Here's an example using the mtcars data set and labs():

ggplot(mtcars, aes(x=mpg, y=disp, size=hp, col=as.factor(cyl), shape=as.factor(gear))) +
  geom_point() +
  labs(x="miles per gallon", y="displacement", size="horsepower", 
       col="# of cylinders", shape="# of gears")

Answering the OP's question using guides():

# transforming the data from wide to long
require(reshape2)
dfm <- melt(df, id="TY")

# creating a scatterplot
ggplot(data = dfm, aes(x=TY, y=value, color=variable)) + 
  geom_point(size=5) +
  labs(title="Temperatures\n", x="TY [°C]", y="Txxx") +
  scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
  theme_bw() +
  guides(color=guide_legend("my title"))  # add guide properties by aesthetic

If you have a file named filelist.txt that is a list paths such as the following: c:/dir1/dir2/file1.h c:/dir1/dir2/dir3/file2.h

then you can do this: rev filelist.txt | cut -d"/" -f1 | rev

Selecting N random items from a group shouldn't have anything to do with order! Randomness is about unpredictability and not about shuffling positions in a group. All the answers that deal with some kinda ordering is bound to be less efficient than the ones that do not. Since efficiency is the key here, I will post something that doesn't change the order of items too much.

1) If you need true random values which means there is no restriction on which elements to choose from (ie, once chosen item can be reselected):

public static List<T> GetTrueRandom<T>(this IList<T> source, int count, 
                                       bool throwArgumentOutOfRangeException = true)
{
    if (throwArgumentOutOfRangeException && count > source.Count)
        throw new ArgumentOutOfRangeException();

    var randoms = new List<T>(count);
    randoms.AddRandomly(source, count);
    return randoms;
}

If you set the exception flag off, then you can choose random items any number of times.

If you have { 1, 2, 3, 4 }, then it can give { 1, 4, 4 }, { 1, 4, 3 } etc for 3 items or even { 1, 4, 3, 2, 4 } for 5 items!

This should be pretty fast, as it has nothing to check.

2) If you need individual members from the group with no repetition, then I would rely on a dictionary (as many have pointed out already).

public static List<T> GetDistinctRandom<T>(this IList<T> source, int count)
{
    if (count > source.Count)
        throw new ArgumentOutOfRangeException();

    if (count == source.Count)
        return new List<T>(source);

    var sourceDict = source.ToIndexedDictionary();

    if (count > source.Count / 2)
    {
        while (sourceDict.Count > count)
            sourceDict.Remove(source.GetRandomIndex());

        return sourceDict.Select(kvp => kvp.Value).ToList();
    }

    var randomDict = new Dictionary<int, T>(count);
    while (randomDict.Count < count)
    {
        int key = source.GetRandomIndex();
        if (!randomDict.ContainsKey(key))
            randomDict.Add(key, sourceDict[key]);
    }

    return randomDict.Select(kvp => kvp.Value).ToList();
}

The code is a bit lengthier than other dictionary approaches here because I'm not only adding, but also removing from list, so its kinda two loops. You can see here that I have not reordered anything at all when count becomes equal to source.Count. That's because I believe randomness should be in the returned set as a whole. I mean if you want 5 random items from 1, 2, 3, 4, 5, it shouldn't matter if its 1, 3, 4, 2, 5 or 1, 2, 3, 4, 5, but if you need 4 items from the same set, then it should unpredictably yield in 1, 2, 3, 4, 1, 3, 5, 2, 2, 3, 5, 4 etc. Secondly, when the count of random items to be returned is more than half of the original group, then its easier to remove source.Count - count items from the group than adding count items. For performance reasons I have used source instead of sourceDict to get then random index in the remove method.

So if you have { 1, 2, 3, 4 }, this can end up in { 1, 2, 3 }, { 3, 4, 1 } etc for 3 items.

3) If you need truly distinct random values from your group by taking into account the duplicates in the original group, then you may use the same approach as above, but a HashSet will be lighter than a dictionary.

public static List<T> GetTrueDistinctRandom<T>(this IList<T> source, int count, 
                                               bool throwArgumentOutOfRangeException = true)
{
    if (count > source.Count)
        throw new ArgumentOutOfRangeException();

    var set = new HashSet<T>(source);

    if (throwArgumentOutOfRangeException && count > set.Count)
        throw new ArgumentOutOfRangeException();

    List<T> list = hash.ToList();

    if (count >= set.Count)
        return list;

    if (count > set.Count / 2)
    {
        while (set.Count > count)
            set.Remove(list.GetRandom());

        return set.ToList();
    }

    var randoms = new HashSet<T>();
    randoms.AddRandomly(list, count);
    return randoms.ToList();
}

The randoms variable is made a HashSet to avoid duplicates being added in the rarest of rarest cases where Random.Next can yield the same value, especially when input list is small.

So { 1, 2, 2, 4 } => 3 random items => { 1, 2, 4 } and never { 1, 2, 2}

{ 1, 2, 2, 4 } => 4 random items => exception!! or { 1, 2, 4 } depending on the flag set.

Some of the extension methods I have used:

static Random rnd = new Random();
public static int GetRandomIndex<T>(this ICollection<T> source)
{
    return rnd.Next(source.Count);
}

public static T GetRandom<T>(this IList<T> source)
{
    return source[source.GetRandomIndex()];
}

static void AddRandomly<T>(this ICollection<T> toCol, IList<T> fromList, int count)
{
    while (toCol.Count < count)
        toCol.Add(fromList.GetRandom());
}

public static Dictionary<int, T> ToIndexedDictionary<T>(this IEnumerable<T> lst)
{
    return lst.ToIndexedDictionary(t => t);
}

public static Dictionary<int, T> ToIndexedDictionary<S, T>(this IEnumerable<S> lst, 
                                                           Func<S, T> valueSelector)
{
    int index = -1;
    return lst.ToDictionary(t => ++index, valueSelector);
}

If its all about performance with tens of 1000s of items in the list having to be iterated 10000 times, then you may want to have faster random class than System.Random, but I don't think that's a big deal considering the latter most probably is never a bottleneck, its quite fast enough..

Edit: If you need to re-arrange order of returned items as well, then there's nothing that can beat dhakim's Fisher-Yates approach - short, sweet and simple..

<xsl:variable name="count" select="count(/Property/long = $parPropId)"/>

Un-tested but I think that should work. I'm assuming the Property nodes are direct children of the root node and therefor taking out your descendant selector for peformance

possibly not so many answers so thinking to share my code which can help someone

df1 = df.select(to_date(df.t, 'yyyy-MM-dd').alias('dt'))
print df1
print df1.show()

output

DataFrame[dt: date]
+----------+
|        dt|
+----------+
|2019-06-22|
+----------+

the above code to convert to date if you want to convert datetime then use to_timestamp. let me know if you have any doubt.

Just copy the parent view's frame to the child-view then add it. After that autoresizing will work. Actually you should only copy the size CGRectMake(0, 0, parentView.frame.size.width, parentView.frame.size.height)

childView.frame = CGRectMake(0, 0, parentView.frame.size.width, parentView.frame.size.height);
[parentView addSubview:childView];

Acording to this page of the Android Team of Wikimedia Apps, a good way of optimize Gradle builds is adding this lines to your ~/.gradle/gradle.properties

org.gradle.daemon=true                                                          
org.gradle.parallel=true
org.gradle.configureondemand=true
org.gradle.jvmargs=-Xmx2048M

For those who do not have the file there are two ways to do it:

1. Add the file locally in your project by creating a file called gradle.properties in the project root or,

2. You can set them globally for all your projects by creating the same file in your home directory (%UserProfile%.gradle on Windows, ~/.gradle on Linux and Mac OS X)

   It is a good practice to set the properties in your home directory, rather than on a project level.

this is better function

function RGB2HTML(red, green, blue)
{
    var decColor =0x1000000+ blue + 0x100 * green + 0x10000 *red ;
    return '#'+decColor.toString(16).substr(1);
}

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.

However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

Just add this section to server, just before the location / {

location /your/folder/to/browse/ {
        autoindex on;
