With jsonlint (like xmllint):

aptitude install python-demjson
jsonlint -f foo.json

To clone that repository via a URL like that: yes, you do need a client, and that client is Git. That will let you make changes, your own branches, merge back in sync with other developers, maintain your own source that you can easily keep up to date without downloading the whole thing each time and writing over your own changes etc. A ZIP file won't let you do that.

It is mostly meant for people who want to develop the source rather than people who just want to get the source one off and not make changes.

But it just so happens you can get a ZIP file as well:

Click on http://github.com/zoul/Finch/ and then click on the green Clone or Download button. See here:

I use org.reflections:

Reflections reflections = new Reflections("com.mycompany");    
Set<Class<? extends MyInterface>> classes = reflections.getSubTypesOf(MyInterface.class);

Another example:

public static void main(String[] args) throws IllegalAccessException, InstantiationException {
    Reflections reflections = new Reflections("java.util");
    Set<Class<? extends List>> classes = reflections.getSubTypesOf(java.util.List.class);
    for (Class<? extends List> aClass : classes) {
        System.out.println(aClass.getName());
        if(aClass == ArrayList.class) {
            List list = aClass.newInstance();
            list.add("test");
            System.out.println(list.getClass().getName() + ": " + list.size());
        }
    }
}

Select's default value should be one of its value in the list. In order to load the select with default value you can use ng-options. A scope variable need to be set in the controller and that variable is assigned as ng-model in HTML's select tag.

I had the the same problem and I solved it that way:

File currentJavaJarFile = new File(Main.class.getProtectionDomain().getCodeSource().getLocation().getPath());   
String currentJavaJarFilePath = currentJavaJarFile.getAbsolutePath();
String currentRootDirectoryPath = currentJavaJarFilePath.replace(currentJavaJarFile.getName(), "");

Try using xmltype.createxml(xml).

As in,

select extract(xmltype.createxml(xml), '//fax').getStringVal() from mytab;

It worked for me.

If you want to improve or manipulate even further.

Try something like this.

Select *
from xmltable(xmlnamespaces('some-name-space' as "ns", 
                                  'another-name-space' as "ns1",
                           ), 
                    '/ns/ns1/foo/bar'
                    passing xmltype.createxml(xml) 
                    columns id varchar2(10) path '//ns//ns1/id',
                            idboss varchar2(500) path '//ns0//ns1/idboss',
                            etc....

Found another way.. I use apple's UIImage+ImageEffects.

 UIImage *effectImage = [image applyExtraLightEffect];                        
 self.imageView.image = effectImage;

On MAC OS X(/BSD): you can try to use the lsof (list open files) command

$ sudo lsof -nPi -sTCP:LISTEN

and so

$ kill -9 3320

For the block element not occupy the whole line, set it's width to something small and the white-space:nowrap

label
{
    width:10px;
    display:block;
    white-space:nowrap;
}

Return min and max value in tuple:

def side_values(num_list):
    results_list = sorted(num_list)
    return results_list[0], results_list[-1]


somelist = side_values([1,12,2,53,23,6,17])
print(somelist)

One solution to this would be a list comprehension, with pattern matching inside your tuple:

>>> mylist = [(25,7),(26,9),(55,10)]
>>> [age for (age,person_id) in mylist if person_id == 10]
[55]

Another way would be using map and filter:

>>> map( lambda (age,_): age, filter( lambda (_,person_id): person_id == 10, mylist) )
[55]

Different timeouts mean different things. When you're working on the client.. you're probably looking mostly at the SendTimeout - check this reference - wonderful and relevant explanation: http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/84551e45-19a2-4d0d-bcc0-516a4041943d/

It says:

Brief summary of binding timeout knobs...

Client side:

SendTimeout is used to initialize the OperationTimeout, which governs the whole interaction for sending a message (including receiving a reply message in a request-reply case).  This timeout also applies when sending reply messages from a CallbackContract method.
OpenTimeout and CloseTimeout are used when opening and closing channels (when no explicit timeout value is passed).
ReceiveTimeout is not used.

Server side:

Send, Open, and Close Timeout same as on client (for Callbacks).
ReceiveTimeout is used by ServiceFramework layer to initialize the session-idle timeout.

You can read more about function types in the language specification in sections 3.5.3.5 and 3.5.5.

The TypeScript compiler will infer types when it can, and this is done you do not need to specify explicit types. so for the greeter example, greet() returns a string literal, which tells the compiler that the type of the function is a string, and no need to specify a type. so for instance in this sample, I have the greeter class with a greet method that returns a string, and a variable that is assigned to number literal. the compiler will infer both types and you will get an error if you try to assign a string to a number.

class Greeter {
    greet() {
        return "Hello, ";  // type infered to be string
    }
} 

var x = 0; // type infered to be number

// now if you try to do this, you will get an error for incompatable types
x = new Greeter().greet(); 

Similarly, this sample will cause an error as the compiler, given the information, has no way to decide the type, and this will be a place where you have to have an explicit return type.

function foo(){
    if (true)
        return "string"; 
    else 
        return 0;
}

This, however, will work:

function foo() : any{
    if (true)
        return "string"; 
    else 
        return 0;
}

I could suggest a step by step approach.

1. Visit GNUwin
2. Download the Setup Program
3. Follow the instructions and install GNUWin. You should pay attention to the directory where your application is being installed. (You will need it later1)
4. Follow these instructions and add make to your environment variables. As I told you before, now it is time to know where your application was installed. FYI: The default directory is C:\Program Files (x86)\GnuWin32\.
5. Now, update the PATH to include the bin directory of the newly installed program. A typical example of what one might add to the path is: ...;C:\Program Files (x86)\GnuWin32\bin

Following code worked for me.

import java.io.UnsupportedEncodingException;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


public class SendMail {

    public static void main(String[] args) {

        final String username = "[email protected]";
        final String password = "yourpassword";

        Properties props = new Properties();
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

        Session session = Session.getInstance(props,
          new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
          });

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("[email protected]"));
            message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("[email protected]"));
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler,"
                + "\n\n No spam to my email, please!");

            Transport.send(message);

            System.out.println("Done");

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

You could run it without the -jar command line argument if you happen to know the name of the main class you wish to run:

java -classpath .;myjar.jar;lib/referenced-class.jar my.package.MainClass

If perchance you are using linux, you should use ":" instead of ";" in the classpath.

There's no single method that will do what you want. You will need to make a clone method available for the class in your array. Then, if LINQ is an option:

Foo[] newArray = oldArray.Skip(3).Take(5).Select(item => item.Clone()).ToArray();

class Foo
{
    public Foo Clone()
    {
        return (Foo)MemberwiseClone();
    }
}

returning true or false indicates that whether execution should continue or stop right there. So just an example

<input type="button" onclick="return func();" />

Now if func() is defined like this

function func()
{
 // do something
return false;
}

the click event will never get executed. On the contrary if return true is written then the click event will always be executed.

Here's a cross-browser CSS-only solution. Hope it helps!

To fix this error from Tools > NuGet Package Manager > Package Manager Console simply run:

dotnet restore

The error occurs because the dotnet cli does not create the all of the required files initially. Doing dotnet restore adds the required files.

You can add virtual columns as

SELECT '1' as temp

But if you tries to put where condition to additionally generated column, it wont work and will show an error message as the column doesn't exist.

We can solve this issue by returning sql result as a table.ie,

SELECT tb.* from (SELECT 1 as temp) as tb WHERE tb.temp = 1

On Angular 6, I access parent properties by injecting the parent via constructor. Not the best solution but it works:

 constructor(@Optional() public parentComponentInjectionObject: ParentComponent){
    // And access like this:
    parentComponentInjectionObject.thePropertyYouWantToAccess;
}

This is also good way to accomplish task.

@if($errors->any())
  {!! implode('', $errors->all('<div class="alert alert-danger">:message</div>')) !!}
@endif

We can format tag as per requirements.

Normally when you try to select a node using xpath your xpath-engine will return null or equivalent if the node doesn't exists.

xpath: "/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml"

If your using xsl check out this question for an answer:

xpath find if node exists

It's been quite a few years since this question was last answered. React introduced "Hooks" back in 2017, and "keyCode" has been deprecated.

Now we can write this:

  useEffect(() => {
    const listener = event => {
      if (event.code === "Enter" || event.code === "NumpadEnter") {
        console.log("Enter key was pressed. Run your function.");
        // callMyFunction();
      }
    };
    document.addEventListener("keydown", listener);
    return () => {
      document.removeEventListener("keydown", listener);
    };
  }, []);

This registers a listener on the keydown event, when the component is loaded for the first time. It removes the event listener when the component is destroyed.

This discussion is still of interest to me. Behind the original post are "requirements" which the OP seems to share - i.e. a form with backward compatibility. As someone whose work at the time of writing must sometimes support back to IE6 (and for years to come), I dig that.

Without pushing the framework (all organizations are going to want to reassure themselves on compatibility/robustness, and I'm not using this discussion as justification for the framework), the Drupal solutions to this issue are interesting. Drupal is also directly relevant because the framework has had a long time policy of "it should work without Javascript (only if you want)" i.e. the OP's issue.

Drupal uses it's rather extensive form.inc functions to find the triggering_element (yes, that's the name in code). See the bottom of the code listed on the API page for form_builder (if you'd like to dig into details, the source is recommended - drupal-x.xx/includes/form.inc). The builder uses automatic HTML attribute generation and, via that, can on return detect which button was pressed, and act accordingly (these can be set up to run separate processes too).

Beyond the form builder, Drupal splits data 'delete' actions into separate URLs/forms, likely for the reasons mentioned in the original post. This needs some sort of search/listing step (groan another form! but is user-friendly) as a preliminary. But this has the advantage of eliminating the "submit everything" issue. The big form with the data is used for it's intended purpose, data creation/updating (or even a 'merge' action).

In other words, one way of working around the problem is to devolve the form into two, then the problem vanishes (and the HTML methods can be corrected through a POST too).

Use OrderedDicts: http://docs.python.org/2/library/collections.html#collections.OrderedDict

>>> x = OrderedDict((("a", "1"), ("c", '3'), ("b", "2")))
>>> x["d"] = 4
>>> x.keys().index("d")
3
>>> x.keys().index("c")
1

For those using Python 3

>>> list(x.keys()).index("c")
1

Use the below code in android.support.v4

FragmentTransaction ft1 = getFragmentManager().beginTransaction();
WebViewFragment w1 = new WebViewFragment();
w1.init(linkData.getLink());
ft1.addToBackStack(linkData.getName());
ft1.replace(R.id.listFragment, w1);
ft1.commit();

This might not be a popular option, but sometimes the scripts end up being distributed in various chunks, in that case I've found this to be a quick fix

if(window.onload != null){var f1 = window.onload;}
window.onload=function(){
    //do something

    if(f1!=null){f1();}
}

then somewhere else...

if(window.onload != null){var f2 = window.onload;}
window.onload=function(){
    //do something else

    if(f2!=null){f2();}
}

this will update the onload function and chain as needed

If you wish to stream the CSV out to the user without creating a file then I found the following to be the simplest method. You can use any extension/method to create the ToCsv() function (which returns a string based on the given DataTable).

        var report = myDataTable.ToCsv();
        var bytes = Encoding.GetEncoding("iso-8859-1").GetBytes(report);

        Response.Buffer = true;
        Response.Clear();
        Response.AddHeader("content-disposition", "attachment; filename=report.csv");
        Response.ContentType = "text/csv";
        Response.BinaryWrite(bytes);
        Response.End();

I tried to get an uwsgi:// working, but somehow the manual thought it was clear to me that I actually needed mod_proxy_uwsgi. It was not. Here is how you do it: How to compile mod_proxy_uwsgi or mod_uwsgi?

This error also happens if you have got the order of your components wrong.

Example: this wrong:

 <ComponentA> 
    <ComponentB> 

    </ComponentA> 
 </ComponentB> 

correct way:

  <ComponentA> 
    <ComponentB>

    </ComponentB>  
  </ComponentA> 

Try opening config-db.php, it's inside /etc/phpmyadmin. In my case, the user was phpmyadmin, and my password was correct. Maybe your problem is that you're using the usual 'root' username, and your password could be correct.

late to the party, was searching for same, as "in" is not valid, I had just created following.

    sub_index = 0
    position = -1
    for ch_i,ch_f in enumerate(full) :
        if ch_f.lower() != sub[sub_index].lower():
            position = -1
            sub_index = 0
        if ch_f.lower() == sub[sub_index].lower():
            if sub_index == 0 :
                position = ch_i

            if (len(sub) - 1) <= sub_index :
                break
            else:
                sub_index += 1

    return position

print(find_str("Happy birthday", "py"))
print(find_str("Happy birthday", "rth"))
print(find_str("Happy birthday", "rh"))

which produces

3
8
-1

remove lower() in case case insensitive find not needed.

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

A bootstrap v3 solution (where the events have different names), also using only one jQuery selector (as seen here):

$('.accordion').on('hide.bs.collapse show.bs.collapse', function (n) {
    $(n.target).siblings('.panel-heading').find('i.glyphicon').toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
});

First check if the user has granted the permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
    == PackageManager.PERMISSION_DENIED)

Then, you could use this to request to the user:

ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);

And in Marshmallow, it will appear in a dialog

Node.js has included experimental support for ES6 support. Read more about here: https://nodejs.org/docs/latest-v13.x/api/esm.html#esm_enabling.

TLDR;

Node.js >= v13

It's very simple in Node.js 13 and above. You need to either:

• Save the file with .mjs extension, or
• Add { "type": "module" } in the nearest package.json.

You only need to do one of the above to be able to use ECMAScript modules.

Node.js <= v12

If you are using Node.js version 8-12, save the file with ES6 modules with .mjs extension and run it like:

node --experimental-modules my-app.mjs

Simplicity is the ultimate sophistication.
If you don't want the text-to-be-coppied to be visible:

jQuery:

$('button.copyButton').click(function(){
    $(this).siblings('input.linkToCopy').select();      
    document.execCommand("copy");
});

HTML:

<button class="copyButton">click here to copy</button>
<input class="linkToCopy" value="TEXT TO COPY"
style="position: absolute; z-index: -999; opacity: 0;" />

A rather simple solution is to create a singleton manager class, in which you can store a reference to one or more Activities, or anything else you want access to throughout the app.

Call UberManager.getInstance().setMainActivity( activity ); in the main activity's onCreate.

Call UberManager.getInstance().getMainActivity(); anywhere in your app to retrieve it. (I am using this to be able to use Toast from a non UI thread.)

Make sure you add a call to UberManager.getInstance().cleanup(); when your app is being destroyed.

import android.app.Activity;

public class UberManager
{
    private static UberManager instance = new UberManager();

    private Activity mainActivity = null;

    private UberManager()
    {

    }

    public static UberManager getInstance()
    {
        return instance;
    }

    public void setMainActivity( Activity mainActivity )
    {
        this.mainActivity = mainActivity;
    }

    public Activity getMainActivity()
    {
        return mainActivity;
    }

    public void cleanup()
    {
        mainActivity = null;
    }
}

Honestly, I've always been happy with emacs. Then again, I started out using emacs, so I've no doubt that it colours my perceptions. Still, it gives syntax highlighting and formatting, and can easily be configured to build the LaTeX. Check out the TeX mode.

In the solution below I used python3.4 as binary, but it's safe to use with any version or binary of python. it works fine on windows too (except the downloading pip with wget obviously but just save the file locally and run it with python).

This is great if you have multiple versions of python installed, so you can manage external libraries per python version.

So first, I'd recommend get-pip.py, it's great to install pip :

wget https://bootstrap.pypa.io/get-pip.py

Then you need to install pip for your version of python, I have python3.4 so for me this is the command :

python3.4 get-pip.py

Now pip is installed for python3.4 and in order to get libraries for python3.4 one need to call it within this version, like this :

python3.4 -m pip

So if you want to install numpy you would use :

python3.4 -m pip install numpy

Note that numpy is quite the heavy library. I thought my system was hanging and failing. But using the verbose option, you can see that the system is fine :

python3.4 -m pip install numpy -v

This may tell you that you lack python.h but you can easily get it :

On RHEL (Red hat, CentOS, Fedora) it would be something like this :

yum install python34-devel

On debian-like (Debian, Ubuntu, Kali, ...) :

apt-get install python34-dev

Then rerun this :

python3.4 -m pip install numpy -v

From the documentation:

list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a),x) is equivalent to a.append(x)

http://docs.python.org/2/tutorial/datastructures.html#more-on-lists

There is one other option also .

row=(Row) sheet.getRow(i);
        if (row == null || isEmptyRow(row)) {
            return;
        }
Iterator<Cell> cells = row.cellIterator();
    while (cells.hasNext())
     {}

I suggest you do some experiments using "make". Here is a simple demo, showing the difference between = and :=.

/* Filename: Makefile*/
x := foo
y := $(x) bar
x := later

a = foo
b = $(a) bar
a = later

test:
    @echo x - $(x)
    @echo y - $(y)
    @echo a - $(a)
    @echo b - $(b)

make test prints:

x - later
y - foo bar
a - later
b - later bar

Follow the steps as below: (Linux)

Edit the file ~/.bashrc, to enter following lines at its end (In case, of Mac, file would be ~/.bash_profile)

# Git branch in prompt.
parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h \W\[\033[32m\]\$(parse_git_branch)\[\033[00m\] $ "

Now, start the new terminal window, and try entering to any git-repo. The current branch would be shown, with the prompt.

You can do it using merge_all in the reshape package. You can pass parameters to merge using the ... argument

reshape::merge_all(list_of_dataframes, ...)

Here is an excellent resource on different methods to merge data frames.

You can use unionByName to make this:

df = df_1.unionByName(df_2)

unionByName is available since Spark 2.3.0.

Note that you can also create your own structures using a Map.Entry as the main type, using its basic implementation AbstractMap.SimpleEntry. For instance, if you wanted to have an ordered list of entries, you could write:

List<Map.Entry<String, Integer>> entries = new ArrayList<>();
entries.add(new AbstractMap.SimpleEntry<String, Integer>(myStringValue, myIntValue));

And so on. From there, you have a list of tuples. Very useful when you want ordered tuples and a basic Map is a no-go.

In xaml

<TextBlock Text="{Binding CelsiusTemp}" />

In ViewModel, this way setting the value also works:

 public string CelsiusTemp
        {
            get { return string.Format("{0}°C", _CelsiusTemp); }
            set
            {
                value = value.Replace("°C", "");
              _CelsiusTemp = value;
            }
        }

Here's what I use:

/* Returns a list of files in a directory (except the ones that begin with a dot) */

void GetFilesInDirectory(std::vector<string> &out, const string &directory)
{
#ifdef WINDOWS
    HANDLE dir;
    WIN32_FIND_DATA file_data;

    if ((dir = FindFirstFile((directory + "/*").c_str(), &file_data)) == INVALID_HANDLE_VALUE)
        return; /* No files found */

    do {
        const string file_name = file_data.cFileName;
        const string full_file_name = directory + "/" + file_name;
        const bool is_directory = (file_data.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) != 0;

        if (file_name[0] == '.')
            continue;

        if (is_directory)
            continue;

        out.push_back(full_file_name);
    } while (FindNextFile(dir, &file_data));

    FindClose(dir);
#else
    DIR *dir;
    class dirent *ent;
    class stat st;

    dir = opendir(directory);
    while ((ent = readdir(dir)) != NULL) {
        const string file_name = ent->d_name;
        const string full_file_name = directory + "/" + file_name;

        if (file_name[0] == '.')
            continue;

        if (stat(full_file_name.c_str(), &st) == -1)
            continue;

        const bool is_directory = (st.st_mode & S_IFDIR) != 0;

        if (is_directory)
            continue;

        out.push_back(full_file_name);
    }
    closedir(dir);
#endif

Adjacent string literals are concatenated at compile time, just as in C. http://docs.python.org/reference/lexical_analysis.html#string-literal-concatenation is a good place to start for more info.

In latin1 each character is exactly one byte long. In utf8 a character can consist of more than one byte. Consequently utf8 has more characters than latin1 (and the characters they do have in common aren't necessarily represented by the same byte/bytesequence).

Option 1: Put this in your procedure to print 'comment' to stdout when it runs.

SELECT 'Comment';

Option 2: Put this in your procedure to print a variable with it to stdout:

declare myvar INT default 0;
SET myvar = 5;
SELECT concat('myvar is ', myvar);

This prints myvar is 5 to stdout when the procedure runs.

Option 3, Create a table with one text column called tmptable, and push messages to it:

declare myvar INT default 0;
SET myvar = 5;
insert into tmptable select concat('myvar is ', myvar);

You could put the above in a stored procedure, so all you would have to write is this:

CALL log(concat('the value is', myvar));

Which saves a few keystrokes.

Option 4, Log messages to file

select "penguin" as log into outfile '/tmp/result.txt';

There is very heavy restrictions on this command. You can only write the outfile to areas on disk that give the 'others' group create and write permissions. It should work saving it out to /tmp directory.

Also once you write the outfile, you can't overwrite it. This is to prevent crackers from rooting your box just because they have SQL injected your website and can run arbitrary commands in MySQL.

I was using the Runnable with sv.fullScroll(View.FOCUS_DOWN); It works perfectly for the immediate problem, but that method makes ScrollView take the Focus from the entire screen, if you make that AutoScroll to happen every time, no EditText will be able to receive information from the user, my solution was use a different code under the runnable:

sv.scrollTo(0, sv.getBottom() + sv.getScrollY());

making the same without losing focus on important views

Since tcp usages are pretty straightforward from other answers, I'll mention some interesting UDP use-cases:

1)DHCP - Dynamic Host Configuration Protocol, which is being used in order to dynamically assign IP address and some other network configuration to the connecting devices. In simple words, this protocol allows you just connect to the network cable(or wifi) and start using the internet, without any additional configurations. DHCP uses UDP protocol. Since the settings request message is being broadcasted from the host and there is no way to establish a TCP connection with DHCP server(you don't know it's address) it's impossible to use TCP instead.

2)Traceroute - well-known network diagnostic tool which allows you to explore which path in the network your datagram passes to reach it's destination(and how much time it takes). By default, it works by sending UDP datagram with unlikely destination port number(ranging from 33434 to 33534) to the destination with the ttl(time-to-live) field set to 1. When the router somewhere in the network gets such datagram - it finds out that the datagram is expired. Then, the router drops the datagram and sends to the origin of the datagram an ICMP(Internet Control Message Protocol) error message indicating that the datagram's ttl was expired and containing router's name and IP address. Each time the host sends datagrams with higher and higher TTL, thus increasing the network part which it succeeds to overcome and getting new ICMP messages from new routers. When it eventually reaches it's destination(datagrams TTL is big enough to allow it),- the destination host sends 'Destination port unreachable' ICMP message to the origin host. This way, Traceroute knows that the destination was reached. Since the TCP guarantees segments delivery it would be at least inefficient to use it instead of UDP which, in turn, allows datagram to be just dropped without any resend attempts(resend is implemented on the higher level, with continuously increasing TTL as described above).

There are 2 different places you can set it:

php.ini

post_max_size=20M
upload_max_filesize=20M

.htaccess / httpd.conf / virtualhost include

php_value post_max_size 20M
php_value upload_max_filesize 20M

Which one to use depends on what you have access to.

.htaccess will not require a server restart, but php.ini and the other apache conf files will.

This should do it:

ALTER TABLE test MODIFY locationExpert VARCHAR(120) 

as a quick oneliner

# just list all the postgres tables sorted in the terminal
db='my_db_name'
clear;psql -d $db -t -c '\dt'|cut -c 11-|perl -ne 's/^([a-z_0-9]*)( )(.*)/$1/; print'

or if you prefer much clearer json output multi-liner :

IFS='' read -r -d '' sql_code <<"EOF_CODE"
    select array_to_json(array_agg(row_to_json(t))) from (
        SELECT table_catalog,table_schema,table_name 
        FROM information_schema.tables
        ORDER BY table_schema,table_name ) t
EOF_CODE
psql -d postgres -t -q -c "$sql_code"|jq

If you need to be checking external pages, you won't be able to get away with a pure javascript solution, since any requests to external URLs are blocked. You can get away with it by using JSONP, but that won't work unless the page you're requesting only serves up JSON.

You need to have a proxy on your own server to get the external links for you. This is actually rather simple with any server-side language.

<?php
$contents = file_get_contents($_GET['url']); // please do some sanitation here...
                                             // i'm just showing an example.
echo $contents;
?>

If you needed to check server response codes (eg: 404, 301, etc), then using a library such as cURL in your server-side script could retrieve that information and then pass it onto your javascript app.

Thinking about it now, there probably could be JSONP-enabled proxies out there for you to use, should the "setting up my own proxy" option not be viable.

Unfortunately, CSS Zen Garden can no longer be used as an example of good HTML/CSS design. Virtually all of their recent designs use graphics for section heading. These graphic files are specified in the CSS.

Hence, a website whose purpose is to show the advantage of keeping design out of content, now regularly commits the UNSPEAKABLE SIN of putting content into design. (If the section heading in the HTML file were to change, the section heading displayed would not).

Which only goes to show that even those advocate the strict DIV & CSS religion, can't follow their own rules. You may use that as a guideline in how closely you follow them.

Another way to fix the problem of too many layers of nested quotation:

You are trying to cram too much into too tiny a space, so use a bash function.

The problem is you are trying to have too many levels of nesting, and the basic alias technology is not powerful enough to accommodate. Use a bash function like this to make it so the single, double quotes back ticks and passed in parameters are all handled normally as we would expect:

lets_do_some_stuff() {
    tmp=$1                       #keep a passed in parameter.
    run_your_program $@          #use all your passed parameters.
    echo -e '\n-------------'    #use your single quotes.
    echo `date`                  #use your back ticks.
    echo -e "\n-------------"    #use your double quotes.
}
alias foobarbaz=lets_do_some_stuff

Then you can use your $1 and $2 variables and single, double quotes and back ticks without worrying about the alias function wrecking their integrity.

This program prints:

el@defiant ~/code $ foobarbaz alien Dyson ring detected @grid 10385
alien Dyson ring detected @grid 10385

Depends a lot on your definition of what a "character" is. If "rune equals a character " is OK for your task (generally it isn't) then the answer by VonC is perfect for you. Otherwise, it should be probably noted, that there are few situations where the number of runes in a Unicode string is an interesting value. And even in those situations it's better, if possible, to infer the count while "traversing" the string as the runes are processed to avoid doubling the UTF-8 decode effort.

I have the error of system.typeintialzationException, which is due to when I tried to move the file like:

 File.Move(DestinationFilePath, SourceFilePath)

That error was due to I had swapped the path actually, correct one is:

 File.Move(SourceFilePath, DestinationFilePath)

Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)

The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B cmd

%SendKeys% "echo off{ENTER}"

set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"

set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"

set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"

%SendKeys% "exit{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));

For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx

For example:

LEFT ARROW    {LEFT}
RIGHT ARROW   {RIGHT}

For anyone looking to do this dynamically then setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom) on the buttons object will assist.

Sample

Button search = (Button) findViewById(R.id.yoursearchbutton);
search.setCompoundDrawables('your_drawable',null,null,null);

You can create the Python dictionary and serialize it to JSON in one line and it's not even ugly.

my_json_string = json.dumps({'key1': val1, 'key2': val2})

This is how I do it:

CSS:

html, body {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}
#content {
    display: table-cell;
    text-align: center;
    vertical-align: middle
}

HTML:

<div id="content">
    Content goes here
</div>

The locks are always taken at DB level:-

Oracle official Document:- To avoid conflicts during a transaction, a DBMS uses locks, mechanisms for blocking access by others to the data that is being accessed by the transaction. (Note that in auto-commit mode, where each statement is a transaction, locks are held for only one statement.) After a lock is set, it remains in force until the transaction is committed or rolled back. For example, a DBMS could lock a row of a table until updates to it have been committed. The effect of this lock would be to prevent a user from getting a dirty read, that is, reading a value before it is made permanent. (Accessing an updated value that has not been committed is considered a dirty read because it is possible for that value to be rolled back to its previous value. If you read a value that is later rolled back, you will have read an invalid value.)

How locks are set is determined by what is called a transaction isolation level, which can range from not supporting transactions at all to supporting transactions that enforce very strict access rules.

One example of a transaction isolation level is TRANSACTION_READ_COMMITTED, which will not allow a value to be accessed until after it has been committed. In other words, if the transaction isolation level is set to TRANSACTION_READ_COMMITTED, the DBMS does not allow dirty reads to occur. The interface Connection includes five values that represent the transaction isolation levels you can use in JDBC.

For me it was :

Use the command as

java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>

The above command will set the mentioned paths to classpath only once for executing the class named TestClass.

If you want to execute more then one classes, then you can follow this

set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"

After this you can execute as many classes as you want just by simply typing

java <your-class-name>

The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)

If you want to set the classpth only once so that it could work for everytime, then do as follows

1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
    a.  Variable Name-     classpath
    b.  Variable Value-    .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.

Remember this will work every time. You don't need to explicitly set the classpath again and again.

NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.

Hope this will help you.

Difference between Spring, Struts and Hibernate are following:

1. Spring is an Application Framework but Struts and hibernate is not.
2. Spring and Hibernate are Light weighted but Struts 2 is not.
3. Spring and Hibernate has layered architecture but Struts 2 doesn't.
4. Spring and Hibernate support loose coupling but Struts 2 doesn't.
5. Struts 2 and Hibernate have tag library but Spring doesn't.
6. Spring and Hibernate have easy integration with ORM technologies but Struts doesn't.
7. Struts 2 has easy integration with client-side technologies but Spring and Hibernate don't have.

I solved this problem instantiating a new Date object in node.js:...

In Javascript, send the Date().toISOString() to nodejs:...

var start_date = new Date(2012, 01, 03, 8, 30);

$.ajax({
    type: 'POST',
    data: { start_date: start_date.toISOString() },
    url: '/queryScheduleCollection',
    dataType: 'JSON'
}).done(function( response ) { ... });

Then use the ISOString to create a new Date object in nodejs:..

exports.queryScheduleCollection = function(db){
    return function(req, res){

        var start_date = new Date(req.body.start_date);

        db.collection('schedule_collection').find(
            { start_date: { $gte: start_date } }
        ).toArray( function (err,d){
            ...
            res.json(d)
        })
    }
};

Note: I'm using Express and Mongoskin.

ONE OF THE approaches for compilers is to allocate a little more memory and store count of elements in the head element.

Example how it could be done: Here

int* i = new int[4];

compiler will allocate sizeof(int)*5 bytes.

int *temp = malloc(sizeof(int)*5)

Will store 4 in first sizeof(int) bytes

*temp = 4;

and set i

i = temp + 1;

So i points to array of 4 elements, not 5.

And

delete[] i;

will be processed following way

int *temp = i - 1;
int numbers_of_element = *temp; // = 4
... call destructor for numbers_of_element elements if needed
... that are stored in temp + 1, temp + 2, ... temp + 4
free (temp)

Should you want to add a new column (say 'count_column') containing the groups' counts into the dataframe:

df.count_column=df.groupby(['col5','col2']).col5.transform('count')

(I picked 'col5' as it contains no nan)

Do the following on your linux box where java works (if u like the terminal way of doing things)

cd ~
mkdir decompiled_code && cd decompiled_code
wget https://bitbucket.org/mstrobel/procyon/downloads/procyon-decompiler-0.5.36.jar
java -jar procyon-decompiler-0.5.36.jar /Path/to/your/jar -o .

NOTE : as @Richard commented "this may be illegal depending on whether you own the copyright to the jar, the country you live in and your purpose for doing it."

1.) Create a sequence of numbers 'seq' from 1 to 1000, and fix the width '-w' (width is determined by length of ending number, in this case 4 digits for 1000).

2.) Also, select which numbers you want using 'sed -n' (in this case, we select numbers 1-100).

3.) 'echo' out each number. Numbers are stored in the variable 'i', accessed using the '$'.

Pros: This code is pretty clean.

Cons: 'seq' isn't native to all Linux systems (as I understand)

for i in `seq -w 1 1000 | sed -n '1,100p'`; 
do 
    echo $i; 
done

I would like to add an answer to this that hasn't been mentioned, as I have tried all of the above to no avail. My specific situation is that I am using semantic-ui, which has built in !important attributes on elements (extremely annoying). I tried everything to override it, only in the end did one thing work (using jquery). It is as follows:

$('.active').css('cssText', 'border-radius: 0px !important');

SOLVED - not rendering border radius correctly in IE 10 and 11

For those not getting the -ms-border-radius: or the border-radius: to work in IE 10,11 And it renders all square then follow these steps:

1. Click on the gear wheel at the top right of the IE browser
2. Click on Compatibility view settings
3. Now uncheck the 2 boxes that are checked by default.

In my case, I was using both @RunWith(MockitoJUnitRunner.class) and MockitoAnnotations.initMocks(this). When I removed MockitoAnnotations.initMocks(this) it worked correctly.

If using javascript is allowed, you can set the display property to an empty string. This will cause it to use the default for that particular element.

var element = document.querySelector('span.selector');

// Set display to empty string to use default for that element
element.style.display = '';

Here is a link to a jsbin.

This is nice because you don't have to worry about the different types of display to revert to (block, inline, inline-block, table-cell, etc).

But, it requires javascript, so if you are looking for a css-only solution, then this is not the solution for you.

Note: This overrides inline styles, but not styles set in css

android:focusableInTouchMode="true"

this gives it to you as a string.

Another difference is that POST generally requires two HTTP operations, whereas GET only requires one.

Edit: I should clarify--for common programming patterns. Generally responding to a POST with a straight up HTML web page is a questionable design for a variety of reasons, one of which is the annoying "you must resubmit this form, do you wish to do so?" on pressing the back button.

yet another edit: As of version 5.2 pluck is not deprecated anymore, it just got new behaviour (same as lists previously - see side-note below):

edit: As of version 5.1 pluck is deprecated, so start using value instead:

DB::table('users')->where('username', $username)->value('groupName');    

// valid for L4 / L5.0 only
DB::table('users')->where('username', $username)->pluck('groupName');

this will return single value of groupName field of the first row found.

SIDE NOTE reg. @TomasButeler comment: As Laravel doesn't follow sensible versioning, there are sometimes cases like this. At the time of writing this answer we had pluck method to get SINGLE value from the query (Laravel 4.* & 5.0).

Then, with L5.1 pluck got deprecated and, instead, we got value method to replace it.

But to make it funny, pluck in fact was never gone. Instead it just got completely new behaviour and... deprecated lists method.. (L5.2) - that was caused by the inconsistency between Query Builder and Collection methods (in 5.1 pluck worked differently on the collection and query, that's the reason).

A bracket - [ or ] - means that end of the range is inclusive -- it includes the element listed. A parenthesis - ( or ) - means that end is exclusive and doesn't contain the listed element. So for [first1, last1), the range starts with first1 (and includes it), but ends just before last1.

Assuming integers:

• (0, 5) = 1, 2, 3, 4
• (0, 5] = 1, 2, 3, 4, 5
• [0, 5) = 0, 1, 2, 3, 4
• [0, 5] = 0, 1, 2, 3, 4, 5

If checked:

$( "SELECTOR" ).attr( "checked" )  // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.

Get the checked val:

$( "SELECTOR:checked" ).val()

Get the checked val numbers:

$( "SELECTOR:checked" ).length

Check or uncheck checkbox

$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );

Use ?:

<form action="?" method="post">

It will send the user back to the same page.

Ruby has Enumerator#with_index(offset = 0), so first convert the array to an enumerator using Object#to_enum or Array#map:

[:a, :b, :c].map.with_index(2).to_a
#=> [[:a, 2], [:b, 3], [:c, 4]]

Generate change SQL queries (FAST)

mysql -e "SELECT CONCAT( 'update ', table_name , ' set ', column_name, ' = replace(', column_name,', ''www.oldsite.com'', ''www.newsite.com'');' ) AS statement FROM information_schema.columns WHERE table_name LIKE 'wp_%'" -u root -p your_db_name_here > upgrade_script.sql

Remove any garbage at the start of the file. I had some.

nano upgrade_script.sql

Run generated script with --force options to skip errors. (SLOW - grab a coffee if big DB)

mysql -u root -p your_db_name_here --force < upgrade_script.sql

You can use generic code inspection via instanceof:

var e = document.getElementById('#my-element');
if (e instanceof HTMLInputElement) {}         // <input>
elseif (e instanceof HTMLSelectElement) {}    // <select>
elseif (e instanceof HTMLTextAreaElement) {}  // <textarea>
elseif (  ... ) {}                            // any interface

Look here for a complete list of interfaces.

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

null is a legal value (and reserved word) in JSON, but some environments do not have a "NULL" object (as opposed to a NULL value) and hence cannot accurately represent the JSON null. So they will sometimes represent it as an empty array.

Whether null is a legal value in that particular element of that particular API is entirely up to the API designer.

Adding to Julia Passynkova's answer

To set validation error in component:

formData.form.controls['email'].setErrors({'incorrect': true});

To unset validation error in component:

formData.form.controls['email'].setErrors(null);

Be careful with unsetting the errors using null as this will overwrite all errors. If you want to keep some around you may have to check for the existence of other errors first:

if (isIncorrectOnlyError){
   formData.form.controls['email'].setErrors(null);
}

I wrote a more general helper class which accepts a string-based dictionary of custom parameters, so that they can be set by the caller without having to hard-code them. It goes without saying that you should only use such method when you want (or need) to manually issue a SOAP-based web service: in most common scenarios the recommended approach would be using the Web Service WSDL together with the Add Service Reference Visual Studio feature instead.

For additional info & details regarding this class you can also read this post on my blog.

Here's another two-div solution. Tried to keep it concise and not hardcoded. First, the expectable html:

<div id="outer">
  <div id="inner">
    content
  </div>
</div>

The principle behind the following css is to position some side of "outer", then use the fact that it assumes the size of "inner" to relatively shift the latter.

#outer {
  position: fixed;
  left: 50%;          // % of window
}
#inner {
  position: relative;
  left: -50%;         // % of outer (which auto-matches inner width)
}

This approach is similar to Quentin's, but inner can be of variable size.

You may want to run it in verbose + force mode.

logrotate -vf /etc/logrotate.conf

my recipe:

datatable declaration:

defaultContent: "<button type='button'....

events:

$('#usersDataTable tbody').on( 'click', '.delete-user-btn', function () { var user_data = table.row( $(this).parents('tr') ).data(); }

Why not set stdout directly to sys.stdout? And if you need to output to a log as well, then you can simply override the write method of f.

import sys
import subprocess

class SuperFile(open.__class__):

    def write(self, data):
        sys.stdout.write(data)
        super(SuperFile, self).write(data)

f = SuperFile("log.txt","w+")       
process = subprocess.Popen(command, stdout=f, stderr=f)

Use Remove()...

string foo = "1234567890";
int trimLength = 5;

if (foo.Length > trimLength) foo = foo.Remove(trimLength);

// foo is now "12345"

a {background-color:transparent !important;}

n = eval(input('Num books: '))
books = {}
for i in range(n):
    titlez = input("Enter Title: ")
    copy = eval(input("Num of copies: "))
    books[titlez] = copy

prob = input('Sell a book; enter YES or NO: ')
if prob == 'YES' or 'yes':
    choice = input('Enter book title: ')
    if choice in books:
        init_num = books[choice]
        init_num -= 1
        books[choice] = init_num
        print(books)

Wildcards worked for me when the string I was searching for could be entered manually. However, I wanted to store this string in another cell and refer to it. I couldn't figure out how to do this with wildcards so I ended up doing the following:

A1 is the cell containing my search string. B and C are the columns within which I want to count the number of instances of A1, including within strings:

=COUNTIF(ARRAYFORMULA(ISNUMBER(SEARCH(A1, B:C))), TRUE)

This is built on some of the previous answers and comments. The following covers all the edge cases and fairly concise as well:

const isNumRegEx = /^-?(\d*\.)?\d+$/;

function isNumeric(n, allowScientificNotation = false) {
    return allowScientificNotation ? 
                !Number.isNaN(parseFloat(n)) && Number.isFinite(n) :
                isNumRegEx.test(n);
}

To answer your question, yes you may pass JSON in the URI as part of a GET request (provided you URL-encode). However, considering your reason for doing this is due to the length of the URI, using JSON will be self-defeating (introducing more characters than required).

I suggest you send your parameters in body of a POST request, either in regular CGI style (param1=val1&param2=val2) or JSON (parsed by your API upon receipt)

$('td').click(function() {
    var myCol = $(this).index();
    var $tr = $(this).closest('tr');
    var myRow = $tr.index();
});

If your artifact is not a dependency of a given project, your best bet is to use a repository search engine. Many of them describes the dependencies of a given artifact.

Try withColumn with the function when as follows:

val sqlContext = new SQLContext(sc)
import sqlContext.implicits._ // for `toDF` and $""
import org.apache.spark.sql.functions._ // for `when`

val df = sc.parallelize(Seq((4, "blah", 2), (2, "", 3), (56, "foo", 3), (100, null, 5)))
    .toDF("A", "B", "C")

val newDf = df.withColumn("D", when($"B".isNull or $"B" === "", 0).otherwise(1))

newDf.show() shows

+---+----+---+---+
|  A|   B|  C|  D|
+---+----+---+---+
|  4|blah|  2|  1|
|  2|    |  3|  0|
| 56| foo|  3|  1|
|100|null|  5|  0|
+---+----+---+---+

I added the (100, null, 5) row for testing the isNull case.

I tried this code with Spark 1.6.0 but as commented in the code of when, it works on the versions after 1.4.0.

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

Add a container div for the image and the caption:

<div class="item">
    <img src=""/>
    <span class="caption">Text below the image</span>
</div>

Then, with a bit of CSS, you can make an automatically wrapping image gallery:

div.item {
    vertical-align: top;
    display: inline-block;
    text-align: center;
    width: 120px;
}
img {
    width: 100px;
    height: 100px;
    background-color: grey;
}
.caption {
    display: block;
}

div.item {_x000D_
    /* To correctly align image, regardless of content height: */_x000D_
    vertical-align: top;_x000D_
    display: inline-block;_x000D_
    /* To horizontally center images and caption */_x000D_
    text-align: center;_x000D_

Updated answer

Instead of using 'anonymous' div and spans, you can also use the HTML5 figure and figcaption elements. The advantage is that these tags add to the semantic structure of the document. Visually there is no difference, but it may (positively) affect the usability and indexability of your pages.

The tags are different, but the structure of the code is exactly the same, as you can see in this updated snippet and fiddle:

<figure class="item">
    <img src=""/>
    <figcaption class="caption">Text below the image</figcaption>
</figure>

figure.item {_x000D_
    /* To correctly align image, regardless of content height: */_x000D_
    vertical-align: top;_x000D_
    display: inline-block;_x000D_
    /* To horizontally center images and caption */_x000D_
    text-align: center;_x000D_
    /* The width of the container also implies margin around the images. */_x000D_
    width: 120px;_x000D_
}_x000D_
img {_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background-color: grey;_x000D_
}_x000D_
.caption {_x000D_
    /* Make the caption a block so it occupies its own line. */_x000D_
    display: block;_x000D_

if you want to completely empty the database and not just delete a model or models attached to it you can do:

rake db:purge

you can also do it on the test database

rake db:test:purge

If you're using jQuery-UI, you must include the jQuery UI CSS package, otherwise the UI components don't know how to be styled.

If you don't like the jQuery UI styles, then you'll have to recreate all the styles it would have otherwise applied.

Fix #1 - jQuery-UI Style

Just include jquery-ui.css and everything should work just fine with the latest supported versions of jquery.

Fix #2 - Bootstrap Theme

There is a project that created a Bootstrap-esque theme for jQuery-UI components called jquery-ui-bootstrap. Just grab the stylesheet from there and you should be all set.

Fix #3 - Manual CSS

If you only need the AutoComplete widget from jQuery-UI's library, you should start by doing a custom build so you don't pull in resources you're not using.

After that, you'll need to style it yourself. Just look at some of the other styles that are applied to jquery's autocomplete.css and theme.css to figure out what styles you'll need to manually replace.

You can use bootstrap's dropdowns.less for inspiration.

Here's a sample CSS that fits pretty well with Bootstrap's default theme:

.ui-autocomplete {
    position: absolute;
    z-index: 1000;
    cursor: default;
    padding: 0;
    margin-top: 2px;
    list-style: none;
    background-color: #ffffff;
    border: 1px solid #ccc;
    -webkit-border-radius: 5px;
       -moz-border-radius: 5px;
            border-radius: 5px;
    -webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
       -moz-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
            box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}
.ui-autocomplete > li {
  padding: 3px 20px;
}
.ui-autocomplete > li.ui-state-focus {
  background-color: #DDD;
}
.ui-helper-hidden-accessible {
  display: none;
}

Tip: Since the dropdown menu hides every time you go to inspect the element (i.e. whenever the input loses focus), for easier debugging of the style, find the control with .ui-autocomplete and remove display: none;.

With the SMS Retriever API, one can Read OTP without declaring android.permission.READ_SMS.

1. Start the SMS retriever

    private fun startSMSRetriever() {
        // Get an instance of SmsRetrieverClient, used to start listening for a matching SMS message.
        val client = SmsRetriever.getClient(this /* context */);

        // Starts SmsRetriever, which waits for ONE matching SMS message until timeout
        // (5 minutes). The matching SMS message will be sent via a Broadcast Intent with
        // action SmsRetriever#SMS_RETRIEVED_ACTION.
        val task: Task<Void> = client.startSmsRetriever();

        // Listen for success/failure of the start Task. If in a background thread, this
        // can be made blocking using Tasks.await(task, [timeout]);
        task.addOnSuccessListener {
            Log.d("SmsRetriever", "SmsRetriever Start Success")
        }

        task.addOnFailureListener {
            Log.d("SmsRetriever", "SmsRetriever Start Failed")
        }
    }

2. Receive messages via Broadcast

    public class MySMSBroadcastReceiver : BroadcastReceiver() {

        override fun onReceive(context: Context?, intent: Intent?) {
            if (SmsRetriever.SMS_RETRIEVED_ACTION == intent?.action && intent.extras!=null) {
                val extras = intent.extras
                val status = extras.get(SmsRetriever.EXTRA_STATUS) as Status

                when (status.statusCode) {
                    CommonStatusCodes.SUCCESS -> {
                        // Get SMS message contents
                        val message = extras.get(SmsRetriever.EXTRA_SMS_MESSAGE) as String
                        Log.e("Message", message);
                        // Extract one-time code from the message and complete verification
                        // by sending the code back to your server.
                    }
                    CommonStatusCodes.TIMEOUT -> {
                        // Waiting for SMS timed out (5 minutes)
                        // Handle the error ...
                    }
                }
            }
        }

    }   


    /**Don't forgot to define BroadcastReceiver in AndroidManifest.xml.*/       
    <receiver android:name=".MySMSBroadcastReceiver" android:exported="true">
        <intent-filter>
            <action android:name="com.google.android.gms.auth.api.phone.SMS_RETRIEVED"/>
        </intent-filter>
    </receiver>

3. Send the one-time code from the verification message to your server

Make sure your SMS format is exactly as below:

<#> Your ExampleApp code is: 123ABC78
fBzOyyp9h6L

1. Be no longer than 140 bytes
2. Begin with the prefix <#>

3. End with an 11-character hash string that identifies your app

   You can compute app hash with following code:

   import android.content.Context
   import android.content.ContextWrapper
   import android.content.pm.PackageManager
   import android.util.Base64
   import android.util.Log
   import java.nio.charset.StandardCharsets
   import java.security.MessageDigest
   import java.security.NoSuchAlgorithmException
   import java.util.*
   
   /**
    * This is a helper class to generate your message hash to be included in your SMS message.
    *
    * Without the correct hash, your app won't recieve the message callback. This only needs to be
    * generated once per app and stored. Then you can remove this helper class from your code.
    *
    * For More Detail: https://developers.google.com/identity/sms-retriever/verify#computing_your_apps_hash_string

The XLSB format is also dedicated to the macros embeded in an hidden workbook file located in excel startup folder (XLSTART).

A quick & dirty test with a xlsm or xlsb in XLSTART folder:

Measure-Command { $x = New-Object -com Excel.Application ;$x.Visible = $True ; $x.Quit() }

0,89s with a xlsb (binary) versus 1,3s with the same content in xlsm format (xml in a zip file) ... :)

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command

Thanks for all the help guys, I appreciate it ;)

On my Ubuntu VM, with 1048 MB total RAM, java -XX:+PrintFlagsFinal -version | grep HeapSize printed : uintx MaxHeapSize := 266338304, which is approx 266MB and is 1/4th of my total RAM.

The right and standard way to do it is using classList. It is now widely supported in the latest version of most modern browsers:

ELEMENT.classList.remove("CLASS_NAME");

remove.onclick = () => {_x000D_
  const el = document.querySelector('#el');_x000D_
  if (el.classList.contains("red")) {_x000D_
    el.classList.remove("red");_x000D_
_x000D_
  }_x000D_
}

.red {_x000D_
  background: red_x000D_
}

<div id='el' class="red"> Test</div>_x000D_
<button id='remove'>Remove Class</button>

I moved my htdocs folder from C:\xampp\htdocs to D:\htdocs without editing the Apache config file (httpd.conf).

Step 1) Move C:\xampp\htdocs folder to D:\htdocs Step 2) Create a symbolic link in C:\xampp\htdocs linked to D:\htdocs using mklink command.

D:\>mklink /J C:\xampp\htdocs D:\htdocs
Junction created for C:\xampp\htdocs <<===>> D:\htdocs

D:\>

Step 3) Done!

I always do OOP and use this class to maintain the session so u can use the function is_logged_in to check if the user is logged in or not, and if not you do what you wish to.

<?php
class Session
{
private $logged_in=false;
public $user_id;

function __construct() {
    session_start();
    $this->check_login();
if($this->logged_in) {
  // actions to take right away if user is logged in
} else {
  // actions to take right away if user is not logged in
}
}

public function is_logged_in() {
   return $this->logged_in;
}

public function login($user) {
// database should find user based on username/password
if($user){
  $this->user_id = $_SESSION['user_id'] = $user->id;
  $this->logged_in = true;
  }
}

public function logout() {
unset($_SESSION['user_id']);
unset($this->user_id);
$this->logged_in = false;
}

private function check_login() {
if(isset($_SESSION['user_id'])) {
  $this->user_id = $_SESSION['user_id'];
  $this->logged_in = true;
} else {
  unset($this->user_id);
  $this->logged_in = false;
 }
}

}

$session = new Session();
?>

I'd suggest using intermediary third table for storing tags<=>items associations, since we have many-to-many relations between tags and items, i.e. one item can be associated with multiple tags and one tag can be associated with multiple items. HTH, Valve.

.aspx uses a full lifecycle (Init, Load, PreRender) and can respond to button clicks etc.
An .ashx has just a single ProcessRequest method.

The SciPy webpage used to provide build and installation instructions, but the instructions there now rely on OS binary distributions. To build SciPy (and NumPy) on operating systems without precompiled packages of the required libraries, you must build and then statically link to the Fortran libraries BLAS and LAPACK:

mkdir -p ~/src/
cd ~/src/
wget http://www.netlib.org/blas/blas.tgz
tar xzf blas.tgz
cd BLAS-*

## NOTE: The selected Fortran compiler must be consistent for BLAS, LAPACK, NumPy, and SciPy.
## For GNU compiler on 32-bit systems:
#g77 -O2 -fno-second-underscore -c *.f                     # with g77
#gfortran -O2 -std=legacy -fno-second-underscore -c *.f    # with gfortran
## OR for GNU compiler on 64-bit systems:
#g77 -O3 -m64 -fno-second-underscore -fPIC -c *.f                     # with g77
gfortran -O3 -std=legacy -m64 -fno-second-underscore -fPIC -c *.f    # with gfortran
## OR for Intel compiler:
#ifort -FI -w90 -w95 -cm -O3 -unroll -c *.f

# Continue below irrespective of compiler:
ar r libfblas.a *.o
ranlib libfblas.a
rm -rf *.o
export BLAS=~/src/BLAS-*/libfblas.a

Execute only one of the five g77/gfortran/ifort commands. I have commented out all, but the gfortran which I use. The subsequent LAPACK installation requires a Fortran 90 compiler, and since both installs should use the same Fortran compiler, g77 should not be used for BLAS.

Next, you'll need to install the LAPACK stuff. The SciPy webpage's instructions helped me here as well, but I had to modify them to suit my environment:

mkdir -p ~/src
cd ~/src/
wget http://www.netlib.org/lapack/lapack.tgz
tar xzf lapack.tgz
cd lapack-*/
cp INSTALL/make.inc.gfortran make.inc          # On Linux with lapack-3.2.1 or newer
make lapacklib
make clean
export LAPACK=~/src/lapack-*/liblapack.a

Update on 3-Sep-2015: Verified some comments today (thanks to all): Before running make lapacklib edit the make.inc file and add -fPIC option to OPTS and NOOPT settings. If you are on a 64bit architecture or want to compile for one, also add -m64. It is important that BLAS and LAPACK are compiled with these options set to the same values. If you forget the -fPIC SciPy will actually give you an error about missing symbols and will recommend this switch. The specific section of make.inc looks like this in my setup:

FORTRAN  = gfortran 
OPTS     = -O2 -frecursive -fPIC -m64
DRVOPTS  = $(OPTS)
NOOPT    = -O0 -frecursive -fPIC -m64
LOADER   = gfortran

On old machines (e.g. RedHat 5), gfortran might be installed in an older version (e.g. 4.1.2) and does not understand option -frecursive. Simply remove it from the make.inc file in such cases.

The lapack test target of the Makefile fails in my setup because it cannot find the blas libraries. If you are thorough you can temporarily move the blas library to the specified location to test the lapack. I'm a lazy person, so I trust the devs to have it working and verify only in SciPy.

You might want to look into the libero FSM generator software. From a state description language and/or a (windows) state diagram editor you may generate code for C, C++, java and many others ... plus nice documentation and diagrams. Source and binaries from iMatix

I am pretty sure that the reason why this problem happened is because of the license of the toolbox (package) in which this function belongs in. Write which divrat and see what will be the result. If it returns path of the function and the comment Has no license available, then the problem is related to the license. That means, license of the package is not set correctly. Mostly it happens if the package (toolbox) of this function is added later, i.e., after installation of the original matlab. Please check and solve the license issue, then it will work fine.

Run below command where pom.xml is placed:

mvn spring-boot:run -Drun.jvmArguments="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"

And start your remote java application with debugging option on port 5005

As already mentioned, creating your own aggregate function is the right thing to do. Here is my concatenation aggregate function (you can find details in French):

CREATE OR REPLACE FUNCTION concat2(text, text) RETURNS text AS '
    SELECT CASE WHEN $1 IS NULL OR $1 = \'\' THEN $2
            WHEN $2 IS NULL OR $2 = \'\' THEN $1
            ELSE $1 || \' / \' || $2
            END; 
'
 LANGUAGE SQL;

CREATE AGGREGATE concatenate (
  sfunc = concat2,
  basetype = text,
  stype = text,
  initcond = ''

);

And then use it as:

SELECT company_id, concatenate(employee) AS employees FROM ...

SELECT
main.CustomerID,
f.Data AS FirstName,
m.Data AS MiddleName,
l.Data AS LastName,
d.Data AS Date
FROM table main
INNER JOIN table f on f.CustomerID = main.CustomerID
INNER JOIN table m on m.CustomerID = main.CustomerID
INNER JOIN table l on l.CustomerID = main.CustomerID
INNER JOIN table d on d.CustomerID = main.CustomerID
WHERE f.DBColumnName = 'FirstName' 
AND m.DBColumnName = 'MiddleName' 
AND l.DBColumnName = 'LastName' 
AND d.DBColumnName = 'Date' 

Edit: I have written this without an editor & have not run the SQL. I hope, you get the idea.

Forms maintain separate resource files (SomeForm.Designer.resx) added via the designer. To use icons embedded in another resource file requires codes. (this.Icone = Project.Resources.SomeIcon;)

I agree with the common answer here that yes you should dispose and no you generally shouldn't set the variable to null... but I wanted to point out that dispose is NOT primarily about memory management. Yes, it can help (and sometimes does) with memory management, but it's primary purpose is to give you deterministic releasing of scarce resources.

For example, if you open a hardware port (serial for example), a TCP/IP socket, a file (in exclusive access mode) or even a database connection you have now prevented any other code from using those items until they are released. Dispose generally releases these items (along with GDI and other "os" handles etc. which there are 1000's of available, but are still limited overall). If you don't call dipose on the owner object and explicitly release these resources, then try to open the same resource again in the future (or another program does) that open attempt will fail because your undisposed, uncollected object still has the item open. Of course, when the GC collects the item (if the Dispose pattern has been implemented correctly) the resource will get released... but you don't know when that will be, so you don't know when it's safe to re-open that resource. This is the primary issue Dispose works around. Of course, releasing these handles often releases memory too, and never releasing them may never release that memory... hence all the talk about memory leaks, or delays in memory clean up.

I have seen real world examples of this causing problems. For instance, I have seen ASP.Net web applications that eventually fail to connect to the database (albeit for short periods of time, or until the web server process is restarted) because the sql server 'connection pool is full'... i.e, so many connections have been created and not explicitly released in so short a period of time that no new connections can be created and many of the connections in the pool, although not active, are still referenced by undiposed and uncollected objects and so can't be reused. Correctly disposing the database connections where necessary ensures this problem doesn't happen (at least not unless you have very high concurrent access).

I don't think there is a "apache-common-like" tool to compare maps since the equality of 2 maps is very ambiguous and depends on the developer needs and the map implementation...

For exemple if you compare two hashmaps in java: - You may want to just compare key/values are the same - You may also want to compare if the keys are ordered the same way - You may also want to compare if the remaining capacity is the same ... You can compare a lot of things!

What such a tool would do when comparing 2 different map implementations such that: - One map allow null keys - The other throw runtime exception on map2.get(null)

You'd better to implement your own solution according to what you really need to do, and i think you already got some answers above :)

In Laravel 5.6, you will need to set it as

  session(['variableName'=>$value]);

To retrieve it is as simple as

$variableName = session('variableName')

In addition to Doug Kavendek answer. One could use the following approach to get closer to tz_database.

1. Download [Free Zip Code Latitude and Longitude Database]
2. Download [A shapefile of the TZ timezones of the world]
3. Use any free library for shapefile querying (e.g. .NET Easy GIS .NET, LGPL).

    var shapeFile = new ShapeFile(shapeFilePath);
    var shapeIndex = shapeFile.GetShapeIndexContainingPoint(new PointD(long, lat), 0D);
    var attrValues = shapeFile.GetAttributeFieldValues(shapeIndex);
    var timeZoneId = attrValues[0];

P.S. Can't insert all the links :( So please use search.

I'm writing common function for change window

this code can be used parallel in all type of project

function changewindow(url,userdata){
    $.ajax({
        type: "POST",
        url: url,
        data: userdata,
        dataType: "html",
        success: function(html){                
            $("#bodycontent").html(html);
        },
        error: function(html){
            alert(html);
        }
    });
}

Or you can do this:

MyString[0];

I was running JUNIT 5 and was also referencing Hamcrest external jar. But Hamcrest is also part of JUNIT 5 library. So, I have to change the order of external Hamecrest jar file up the JUNIT 5 library in build path.

Handy one liner to parse a CSV file into an array

$csv = array_map('str_getcsv', file('data.csv'));

Check /var/lib/php/session and its permissions. This dir should be writable by user so the session can be stored

run this :

chown -R mysql:mysql /var/lib/mysql

and try again!

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY

It's possible to change default fonts, both for the axes and for other text, by adding the following lines to the startup.m file.

% Change default axes fonts.
set(0,'DefaultAxesFontName', 'Times New Roman')
set(0,'DefaultAxesFontSize', 14)

% Change default text fonts.
set(0,'DefaultTextFontname', 'Times New Roman')
set(0,'DefaultTextFontSize', 14)

If you don't know if you have a startup.m file, run

which startup

to find its location. If Matlab says there isn't one, run

userpath

to know where it should be placed.

@theczechsensation's solution is already half way there.

For those who like to exclude noisy log messages and keep the log to their app only this is the solution:

Add your exclusions to Log Tag like this: ^(?!(eglCodecCommon|tagToExclude))

Add your package name or prefix to Package Name: com.mycompany.

This way it is possible to filter for as many strings you like and keep the log to your package.

The easiest fix is to just float the container. (eg. float: left;) On another note, each id should be unique, meaning you can't use the same id twice in the same HTML document. You should use classes instead, where you can use the same class for multiple elements.

.container {
    position: relative;
    background: rgb(255, 100, 0);
    margin: 0;
    width: 40%;
    height: 100px;
    float: left;
}

If error related to Cocoapods as follow:

library not found for -lPod-...

You need to check Other Linker Flags and remove it from there.

Extra Information: If you have an old project that uses cocoapods. And recently you needed to add the use_frameworks! to your podfile. cocoapods will not add the libraries to your Other Linker Flags anymore cause its inherited. Therefore, you may need to remove those manually from the other linker flags which they were added before using the use_frameworks!

I think I have found an easy hack out.

Delete the file that you have on the local repository (the file that you want updated from the latest commit in the remote server)

And then do a git pull

Because the file is deleted, there will be no conflict

<?php
$args     = array( 'post_type' => 'product', 'category' => 34, 'posts_per_page' => -1 );
$products = get_posts( $args ); 
?>

This should grab all the products you want, I may have the post type wrong though I can't quite remember what woo-commerce uses for the post type. It will return an array of products

For me, this is the clearest and most intuitive:

values = []
for action in ['Sell','Buy']:
    amounts = orders_df['Amounts'][orders_df['Action'==action]].values
    if action == 'Sell':
        prices = orders_df['Prices'][orders_df['Action'==action]].values
    else:
        prices = -1*orders_df['Prices'][orders_df['Action'==action]].values
    values += list(amounts*prices)  
orders_df['Values'] = values

The .values method returns a numpy array allowing you to easily multiply element-wise and then you can cumulatively generate a list by 'adding' to it.

Usually, if the command is an external program, you can use the OS to help you here.

command > file_output.txt

So your C code would be doing something like

exec("command > file_output.txt");

Then you can use the file_output.txt file.

Try this code

if ($(window).width() < 960) {
 alert('width is less than 960px');
}
else {
 alert('More than 960');
}

   if ($(window).width() < 960) {_x000D_
     alert('width is less than 960px');_x000D_
    }_x000D_
    else {_x000D_
     alert('More than 960');_x000D_
    }

Here's how you do this with react-router v2.0.0 with ES6. react-router has moved away from mixins.

import React from 'react';

export default class MyComponent extends React.Component {
  navigateToPage = () => {
    this.context.router.push('/my-route')
  };

  render() {
    return (
      <button onClick={this.navigateToPage}>Go!</button>
    );
  }
}

MyComponent.contextTypes = {
  router: React.PropTypes.object.isRequired
}

This can be a quick hack to connect hive and python,

from pyhive import hive
cursor = hive.connect('YOUR_HOST_NAME').cursor()
cursor.execute('SELECT * from table_name LIMIT 5',async=True)
print cursor.fetchall()

Output: List of Tuples

This draws an arc with the center in the specified rectangle. You can draw, half-circles, quarter-circles, etc.

g.drawArc(x - r, y - r, r * 2, r * 2, 0, 360)

This is a speed test about different ways to test "Boolean" values in Bash:

#!/bin/bash
rounds=100000

b=true # For true; b=false for false
type -a true
time for i in $(seq $rounds); do command $b; done
time for i in $(seq $rounds); do $b; done
time for i in $(seq $rounds); do [ "$b" == true ]; done
time for i in $(seq $rounds); do test "$b" == true; done
time for i in $(seq $rounds); do [[ $b == true ]]; done

b=x; # Or any non-null string for true; b='' for false
time for i in $(seq $rounds); do [ "$b" ]; done
time for i in $(seq $rounds); do [[ $b ]]; done

b=1 # Or any non-zero integer for true; b=0 for false
time for i in $(seq $rounds); do ((b)); done

It would print something like

true is a shell builtin
true is /bin/true

List<T> has a Reverse() method, however it only reverses the order of two (or more) consecutive items.

your_list.Reverse(index, 2);

Where the second parameter 2 indicates we are reversing the order of 2 items, starting with the item at the given index.

I solved this error by add below user-permission in AndroidManifest.xml

Also, Initialize Alert dialog with Activity Name:

AlertDialog.Builder builder = new AlertDialog.Builder(YourActivity.this);

var elemScrolPosition = elem.scrollHeight - elem.scrollTop - elem.clientHeight;

It calculates distance scroll bar to bottom of element. Equal 0, if scroll bar has reached bottom.

This solved the issue for me:

pip install -I --upgrade psutil --force

Afterwards just uninstall psutil with the new version and hop you can suddenly install the older version (:

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.text span {
       background:rgba(165, 220, 79, 0.8);
       float: left;
       clear: left;
       padding:7px 10px;
       color:white;
    }

Note:Remove <br/>'s before using this off course.

Well, I did this like this:

dgvReport.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;
dgvReport.AutoResizeColumns();
dgvReport.AllowUserToResizeColumns = true;
dgvReport.AllowUserToOrderColumns = true;

in that particular order. Columns are resized (extended) AND the user can resize columns afterwards.

array_push($arr, ['key1' => $value1, 'key2' => value2]);

This works just fine. creates the the key with its value in the array

Like others have mentioned, you probably want to look at reusing an existing graphing solution, but rotating text isn't too difficult. The somewhat confusing bit (to me) is that you rotate the whole context and then draw on it:

ctx.rotate(Math.PI*2/(i*6));

The angle is in radians. The code is taken from this example, which I believe was made for the transformations part of the MDC canvas tutorial.

Please see the answer below for a more complete solution.

2. mongod --dbpath=C:/data/db --port 27017 --logpath C:/data/log/log.txt --service
3. mongod --dbpath=C:/data/db --port 27017 --logpath C:/data/log/log.txt --install

No, only part of ten digits number can be stored in a unsigned long int whose valid range is 0 to 4,294,967,295 . you can refer to this: http://msdn.microsoft.com/en-us/library/s3f49ktz(VS.80).aspx

For this purpose, you can create your own function. For example:

$ echo 'mkfile() { mkdir -p "$(dirname "$1")" && touch "$1" ;  }' >> ~/.bashrc
$ source ~/.bashrc
$ mkfile ./fldr1/fldr2/file.txt

Explanation:

• Insert the function to the end of ~/.bashrc file using the echo command
• The -p flag is for creating the nested folders, such as fldr2
• Update the ~/.bashrc file with the source command
• Use the mkfile function to create the file

No need of JQuery simply you can do

if(yourObject['email']){
 // what if this property exists.
}

as with any value for email will return you true, if there is no such property or that property value is null or undefined will result to false

Use rgba value for the backgroundColor.

For example,

backgroundColor: 'rgba(52, 52, 52, 0.8)'

This sets it to a grey color with 80% opacity, which is derived from the opacity decimal, 0.8. This value can be anything from 0.0 to 1.0.

@cms way is the more recent, suggested in MS website, but I had a hard problem to solve, with both method posted here, now I post the solution for all!

problem: if you use an url like this: www.somesite.it/?p=1500 in some case you get an internal server error (500), although in web browser this www.somesite.it/?p=1500 perfectly work.

solution: you have to move out parameters, working code is:

using System.Net;
//...
using (WebClient client = new WebClient ()) 
{
    client.QueryString.Add("p", "1500"); //add parameters
    string htmlCode = client.DownloadString("www.somesite.it");
    //...
}

No, there is not really any other way : if you have many locations and want to display them on a map, the best solution is to :

• fetch the latitude+longitude, using the geocoder, when a location is created
• store those in your database, alongside the address
• and use those stored latitude+longitude when you want to display the map.

This is, of course, considering that you have a lot less creation/modification of locations than you have consultations of locations.

Yes, it means you'll have to do a bit more work when saving the locations -- but it also means :

• You'll be able to search by geographical coordinates
  • i.e. "I want a list of points that are near where I'm now"
• Displaying the map will be a lot faster
  • Even with more than 20 locations on it
• Oh, and, also (last but not least) : this will work ;-)
  • You will less likely hit the limit of X geocoder calls in N seconds.
  • And you will less likely hit the limit of Y geocoder calls per day.

1. Enhanced For Loop (Java)

for (Object obj : list);

2. Enhanced For Each in arraylist (Java)

ArrayList<Integer> list = new ArrayList<Integer>(); 
list.forEach((n) -> System.out.println(n)); 

You are using an adjacent sibling selector (+) when the elements are not siblings. The label is the parent of the input, not it's sibling.

CSS has no way to select an element based on it's descendents (nor anything that follows it).

You'll need to look to JavaScript to solve this.

Alternatively, rearrange your markup:

<input id="foo"><label for="foo">…</label>

From http://codecorner.galanter.net/2012/06/04/solution-for-operation-is-not-valid-due-to-the-current-state-of-the-object-error/

Issue happens because Microsoft Security Update MS11-100 limits number of keys in Forms collection during HTTP POST request. To alleviate this problem you need to increase that number.

This can be done in your application Web.Config in the <appSettings> section (create the section directly under <configuration> if it doesn’t exist). Add 2 lines similar to the lines below to the section:

<add key="aspnet:MaxHttpCollectionKeys" value="2000" />
<add key="aspnet:MaxJsonDeserializerMembers" value="2000" />

The above example set the limit to 2000 keys. This will lift the limitation and the error should go away.

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

Another way is to download source code then change following vaiables in variables.less

@font-family-sans-serif:  "Helvetica Neue", Helvetica, Arial, sans-serif;
@font-family-serif:       Georgia, "Times New Roman", Times, serif;
//** Default monospace fonts for `<code>`, `<kbd>`, and `<pre>`.
@font-family-monospace:   Menlo, Monaco, Consolas, "Courier New", monospace;
@font-family-base:        @font-family-sans-serif;

And then compile it to .css file

If you a framework like Bootstrap you can make any iframe video responsive by using this snippet:

<div class="embed-responsive embed-responsive-16by9">
    <iframe class="embed-responsive-item" src="vid.mp4" allowfullscreen></iframe>
</div>

you should you use following code

$configValue = Mage::getStoreConfig(
                   'sectionName/groupName/fieldName',
                   Mage::app()->getStore()
               ); 

Mage::app()->getStore() this will add store code in fetch values so that you can get correct configuration values for current store this will avoid incorrect store's values because magento is also use for multiple store/views so must add store code to fetch anything in magento.

if we have more then one store or multiple views configured then this will insure that we are getting values for current store

Here is an example from my HOW TO Matlab page:

close all; clear all;

img   = imread('lena.tif','tif');
imagesc(img)
img   = fftshift(img(:,:,2));
F     = fft2(img);

figure;

imagesc(100*log(1+abs(fftshift(F)))); colormap(gray); 
title('magnitude spectrum');

figure;
imagesc(angle(F));  colormap(gray);
title('phase spectrum');

This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.

ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say

img = imread('ngc6543a.jpg');

and it will work. I used an older version of Matlab to make the above example and just copied it here.

On the scaling factor

When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c value in the equation

s = c log(1+r) 

There is no known way to pre detrmine this scale that I know. Just need to try different values to get on you like. I used 100 in the above example.

You can Try using :- git ls-files -s

Using jQuery

$('#note textarea');

or just

$('#textid');

You can use somthing like this.

render () {
    var btnClass = 'btn';
    if (this.state.isPressed) btnClass += ' btn-pressed';
    else if (this.state.isHovered) btnClass += ' btn-over';
    return <button className={btnClass}>{this.props.label}</button>;
  }

Or else, you can use classnames NPM package to make dynamic and conditional className props simpler to work with (especially more so than conditional string manipulation).

classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'

You can also use below mentioned code

Response.Write("<script type='text/javascript'>"); Response.Write("window.location = '" + redirect url + "'</script>");Response.Flush();

var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; ++i) {
  // ...
}

It is very simple

public void onClick(View v) {

        imgButton.setImageResource(R.drawable.ic_launcher);

    }

Using set Background image resource will chanage the background of the button

<?php
if(!@mysql_connect('127.0.0.1', 'root', '*your default password*'))
{
    echo "mysql not connected ".mysql_error();
    exit;

}
echo 'great work';
?>

if no error then you will get greatwork as output.

Try it saved my life XD XD

Documenting another scenario after burning way too much time.

Make sure you don't have a dependency jar that has a class with an EJB annotation on it.

We had a common jar file that had an @local annotation. That class was later moved out of that common project and into our main ejb jar project. Our ejb jar and our common jar are both bundled within an ear. The version of our common jar dependency was not updated. Thus 2 classes trying to be something with incompatible changes.

You can use Reflection to do this: (from my library - this gets the names and values)

public static Dictionary<string, object> DictionaryFromType(object atype)
{
    if (atype == null) return new Dictionary<string, object>();
    Type t = atype.GetType();
    PropertyInfo[] props = t.GetProperties();
    Dictionary<string, object> dict = new Dictionary<string, object>();
    foreach (PropertyInfo prp in props)
    {
        object value = prp.GetValue(atype, new object[]{});
        dict.Add(prp.Name, value);
    }
    return dict;
}

This thing will not work for properties with an index - for that (it's getting unwieldy):

public static Dictionary<string, object> DictionaryFromType(object atype, 
     Dictionary<string, object[]> indexers)
{
    /* replace GetValue() call above with: */
    object value = prp.GetValue(atype, ((indexers.ContainsKey(prp.Name)?indexers[prp.Name]:new string[]{});
}

Also, to get only public properties: (see MSDN on BindingFlags enum)

/* replace */
PropertyInfo[] props = t.GetProperties();
/* with */
PropertyInfo[] props = t.GetProperties(BindingFlags.Public)

This works on anonymous types, too!
To just get the names:

public static string[] PropertiesFromType(object atype)
{
    if (atype == null) return new string[] {};
    Type t = atype.GetType();
    PropertyInfo[] props = t.GetProperties();
    List<string> propNames = new List<string>();
    foreach (PropertyInfo prp in props)
    {
        propNames.Add(prp.Name);
    }
    return propNames.ToArray();
}

And it's just about the same for just the values, or you can use:

GetDictionaryFromType().Keys
// or
GetDictionaryFromType().Values

But that's a bit slower, I would imagine.

if you want to add new text before or after the selected colum:

• press ctrl+v
• select columns
• press shift+i
• write your text
• press esc
• press "jj"

To install and run any version of Python in the same system follow my guide below.

For example say you want to install Python 2.x and Python 3.x on the same Windows system.

1. Install both of their binary releases anywhere you want.

   • When prompted do not register their file extensions and
   • do not add them automatically to the PATH environment variable

2. Running simply the command python the executable that is first met in PATH will be chosen for launch. In other words, add the Python directories manually. The one you add first will be selected when you type python. Consecutive python programs (increasing order that their directories are placed in PATH) will be chosen like so:

   • py -2 for the second python
   • py -3 for the third python etc..

3. No matter the order of "pythons" you can:

   • run Python 2.x scripts using the command: py -2 (Python 3.x functionality) (ie. the first Python 2.x installation program found in your PATH will be selected)
   • run Python 3.x scripts using the command: or py -3 (ie. the first Python 3.x installation program found in your PATH will be selected)

In my example I have Python 2.7.14 installed first and Python 3.5.3. This is how my PATH variable starts with:

PATH=C:\Program Files\Microsoft MPI\Bin\;C:\Python27;C:\Program Files\Python_3.6\Scripts\;C:\Program Files\Python_3.6\;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Common Files\Intel\Shared

...

Note that Python 2.7 is first and Python 3.5 second.

• So running python command will launch python 2.7 (if Python 3.5 the same command would launch Python 3.5).
• Running py -2 launches Python 2.7 (because it happens that the second Python is Python 3.5 which is incompatible with py -2). Running py -3 launches Python 3.5 (because it's Python 3.x)
• If you had another python later in your path you would launch like so: py -4. This may change if/when Python version 4 is released.

Now py -4 or py -5 etc. on my system outputs: Requested Python version (4) not installed or Requested Python version (5) not installed etc.

Hopefully this is clear enough.

One issue which doesn't seem to have been mentioned is that this error can crop up due to a problem with the code that has nothing to do with indentation.

For example, take the following script:

def add_one(x):
    try:
        return x + 1
add_one(5)

This returns an IndentationError: unexpected unindent when the problem is of course a missing except: statement.

My point: check the code above where the unexpected (un)indent is reported!
