I use the plugin Chrome extension works pretty well:

One thing that caused me a massive headache when using this code (might affect others and I wish that somebody had left a comment like this one here for me to read):

• My aim is to create a dynamic access dashboard, which requires that its linked tables be updated.
• I use the copy methods described above to replace the existing linked CSVs with an updated version of them.
• Running the above code manually from a module worked fine.
• Running identical code from a form linked to the CSV data had runtime error 70 (Permission denied), even tho the first step of my code was to close that form (which should have unlocked the CSV file so that it could be overwritten).
• I now believe that despite the form being closed, it keeps the outdated CSV file locked while it executes VBA associated with that form.

My solution will be to run the code (On timer event) from another hidden form that opens with the database.

Note: If you just want to stop MySQL server, this might be helpful. In my case, it kept on restarting as soon as I killed the process using PID. Also brew stop command didn't work as I installed without using homebrew. Then I went to mac system preferences and we have MySQL installed there. Just open it and stop the MySQL server and you're done. Here in the screenshot, you can find MySQL in bottom of system preferences.

Assuming your Generic List is of type String:

TextWriter tw = new StreamWriter("SavedList.txt");

foreach (String s in Lists.verbList)
   tw.WriteLine(s);

tw.Close();

Alternatively, with the using keyword:

using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
   foreach (String s in Lists.verbList)
      tw.WriteLine(s);
}

Consider this snippet of code. Modify as you see fit, or to fit your requirements. You'll need to have Imports statements for System.IO and System.Data.OleDb.

Dim fi As New FileInfo("c:\foo.csv")
Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Text;Data Source=" & fi.DirectoryName

Dim conn As New OleDbConnection(connectionString)
conn.Open()

'the SELECT statement is important here, 
'and requires some formatting to pull dates and deal with headers with spaces.
Dim cmdSelect As New OleDbCommand("SELECT Foo, Bar, FORMAT(""SomeDate"",'YYYY/MM/DD') AS SomeDate, ""SOME MULTI WORD COL"", FROM " & fi.Name, conn)

Dim adapter1 As New OleDbDataAdapter
adapter1.SelectCommand = cmdSelect

Dim ds As New DataSet
adapter1.Fill(ds, "DATA")

myDataGridView.DataSource = ds.Tables(0).DefaultView 
myDataGridView.DataBind
conn.Close()

In PostgreSQL 9.2 and above, to disconnect everything except your session from the database you are connected to:

SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE datname = current_database()
  AND pid <> pg_backend_pid();

In older versions it's the same, just change pid to procpid. To disconnect from a different database just change current_database() to the name of the database you want to disconnect users from.

You may want to REVOKE the CONNECT right from users of the database before disconnecting users, otherwise users will just keep on reconnecting and you'll never get the chance to drop the DB. See this comment and the question it's associated with, How do I detach all other users from the database.

If you just want to disconnect idle users, see this question.

If you still can not unmount or remount your device after stopping all services and processes with open files, then there may be a swap file or swap partition keeping your device busy. This will not show up with fuser or lsof. Turn off swapping with:

sudo swapoff -a

You could check beforehand and show a summary of any swap partitions or swap files with:

swapon -s

or:

cat /proc/swaps

As an alternative to using the command sudo swapoff -a, you might also be able to disable the swap by stopping a service or systemd unit. For example:

sudo systemctl stop dphys-swapfile

or:

sudo systemctl stop var-swap.swap

In my case, turning off swap was necessary, in addition to stopping any services and processes with files open for writing, so that I could remount my root partition as read only in order to run fsck on my root partition without rebooting. This was necessary on a Raspberry Pi running Raspbian Jessie.

is the ajax uploader refreshing your input element? if so you should consider using .live() method.

 $('#imageFile').live('change', function(){ uploadFile(); });

update:

from jQuery 1.7+ you should use now .on()

 $(parent_element_selector_here or document ).on('change','#imageFile' , function(){ uploadFile(); });

I had the same problem when connecting to GitHub, which requires a user agent. Thus it is sufficient to provide this rather than generating a certificate

var client = new HttpClient();

client.BaseAddress = new Uri("https://api.github.com");
client.DefaultRequestHeaders.Add(
    "Authorization",
    "token 123456789307d8c1d138ddb0848ede028ed30567");
client.DefaultRequestHeaders.Accept.Add(
    new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add(
    "User-Agent",
    "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36");

I would prefer to have the framework do the logging for you by hooking in a logging stream which logs as the framework processes that underlying stream. The following isn't as clean as I would like it, since you can't decide between request and response in the ChainStream method. The following is how I handle it. With thanks to Jon Hanna for the overriding a stream idea

It works the same way for axes: parse(text='70^o*N') will raise the o as a superscript (the *N is to make sure the N doesn't get raised too).

labelsX=parse(text=paste(abs(seq(-100, -50, 10)), "^o ", "*W", sep=""))
labelsY=parse(text=paste(seq(50,100,10), "^o ", "*N", sep=""))
plot(-100:-50, 50:100, type="n", xlab="", ylab="", axes=FALSE)
axis(1, seq(-100, -50, 10), labels=labelsX)
axis(2, seq(50, 100, 10), labels=labelsY)
box()

To do this without LINQ on .Net2.0:

List<Order> objListOrder = GetOrderList();
objListOrder.Sort(
    delegate(Order p1, Order p2)
    {
        return p1.OrderDate.CompareTo(p2.OrderDate);
    }
);

If you're on .Net3.0, then LukeH's answer is what you're after.

To sort on multiple properties, you can still do it within a delegate. For example:

orderList.Sort(
    delegate(Order p1, Order p2)
    {
        int compareDate = p1.Date.CompareTo(p2.Date);
        if (compareDate == 0)
        {
            return p2.OrderID.CompareTo(p1.OrderID);
        }
        return compareDate;
    }
);

This would give you ascending dates with descending orderIds.

However, I wouldn't recommend sticking delegates as it will mean lots of places without code re-use. You should implement an IComparer and just pass that through to your Sort method. See here.

public class MyOrderingClass : IComparer<Order>
{
    public int Compare(Order x, Order y)
    {
        int compareDate = x.Date.CompareTo(y.Date);
        if (compareDate == 0)
        {
            return x.OrderID.CompareTo(y.OrderID);
        }
        return compareDate;
    }
}

And then to use this IComparer class, just instantiate it and pass it to your Sort method:

IComparer<Order> comparer = new MyOrderingClass();
orderList.Sort(comparer);

I encounter the same problem, and @Joe Kington and @bvanlew's answer solve my problem.

but I should add more infomation when you use pycharm and enable auto import.

when you format the code, the code from mpl_toolkits.mplot3d import Axes3D will auto remove by pycharm.

so, my solution is

from mpl_toolkits.mplot3d import Axes3D
Axes3D = Axes3D  # pycharm auto import
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

and it works well!

Use the View for your efforts in altering the position of the column: CREATE VIEW CORRECTED_POSITION AS SELECT co1_1, col_3, col_2 FROM UNORDERDED_POSITION should help.

This requests are made so some reports get produced where it is using SELECT * FROM [table_name]. Or, some business has a hierarchy approach of placing the information in order for better readability from the back end.

Here's the code to do a nice smooth fade between two Activities..

Create a file called fadein.xml in res/anim

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
   android:interpolator="@android:anim/accelerate_interpolator"
   android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="2000" />

Create a file called fadeout.xml in res/anim

<?xml version="1.0" encoding="utf-8"?>

<alpha xmlns:android="http://schemas.android.com/apk/res/android"
   android:interpolator="@android:anim/accelerate_interpolator"
   android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="2000" />

If you want to fade from Activity A to Activity B, put the following in the onCreate() method for Activity B. Before setContentView() works for me.

overridePendingTransition(R.anim.fadein, R.anim.fadeout);

If the fades are too slow for you, change android:duration in the xml files above to something smaller.

The following script set the sequence to a desired value:

Given a freshly created sequence named PCS_PROJ_KEY_SEQ and table PCS_PROJ:

BEGIN
   DECLARE
      PROJ_KEY_MAX       NUMBER := 0;
      PROJ_KEY_CURRVAL   NUMBER := 0;
   BEGIN

    SELECT MAX (PROJ_KEY) INTO PROJ_KEY_MAX FROM PCS_PROJ;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE PCS_PROJ_KEY_SEQ INCREMENT BY ' || PROJ_KEY_MAX;
    SELECT PCS_PROJ_KEY_SEQ.NEXTVAL INTO PROJ_KEY_CURRVAL FROM DUAL;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE PCS_PROJ_KEY_SEQ INCREMENT BY 1';

END;
END;

Should a dictionary like:

{'red': '0.500', 'yellow': '0.250, 'blue': '0.125'}

be required out of a dataframe like:

        a      b
0     red  0.500
1  yellow  0.250
2    blue  0.125

simplest way would be to do:

dict(df.values)

working snippet below:

import pandas as pd
df = pd.DataFrame({'a': ['red', 'yellow', 'blue'], 'b': [0.5, 0.25, 0.125]})
dict(df.values)

Unfortunately historical ticker data that is free is hard to come by. Now that opentick is dead, I dont know of any other provider.

In a previous lifetime I worked for a hedgefund that had an automated trading system, and we used historical data profusely.

We used TickData for our source. Their prices were reasonable, and the data had sub second resolution.

Control characters:

(Hex codes assume an ASCII-compatible character encoding.)

• \a = \x07 = alert (bell)
• \b = \x08 = backspace
• \t = \x09 = horizonal tab
• \n = \x0A = newline (or line feed)
• \v = \x0B = vertical tab
• \f = \x0C = form feed
• \r = \x0D = carriage return
• \e = \x1B = escape (non-standard GCC extension)

Punctuation characters:

• \" = quotation mark (backslash not required for '"')
• \' = apostrophe (backslash not required for "'")
• \? = question mark (used to avoid trigraphs)
• \\ = backslash

Numeric character references:

• \ + up to 3 octal digits
• \x + any number of hex digits
• \u + 4 hex digits (Unicode BMP, new in C++11)
• \U + 8 hex digits (Unicode astral planes, new in C++11)

\0 = \00 = \000 = octal ecape for null character

If you do want an actual digit character after a \0, then yes, I recommend string concatenation. Note that the whitespace between the parts of the literal is optional, so you can write "\0""0".

The documentation you linked actually has the answer in the link associated with the "Java class located out of the source root." Configure your source and test roots and it should work.

https://www.jetbrains.com/idea/webhelp/configuring-content-roots.html

Since you stated that these are tests you should probably go with them marked as Test Source Root instead of Source Root.

Try this:

$('element').attr('id', 'value');

So it becomes;

$(function() {
    $('span .breadcrumb').each(function(){
        $('#nav').attr('id', $(this).text());
        $('#container').attr('id', $(this).text());
        $('.stretch_footer').attr('id', $(this).text())
        $('#footer').attr('id', $(this).text());
    });
});

So you are changing/overwriting the id of three elements and adding an id to one element. You can modify as per you needs...

Simply use

ax.set_xticklabels(label_list, rotation=45)

Using unless is fine for statements with single include? clauses but, for example, when you need to check the inclusion of something in one Array but not in another, the use of include? with exclude? is much friendlier.

if @players.include? && @spectators.exclude? do
  ....
end

But as dizzy42 says above, the use of exclude? requires ActiveSupport

This error message happens either because your ProfileDto class is not registered in the JAXB Content, or the class using it does not use @XmlSeeAlso(ProfileDto.class) to make processable by JAXB.

About your comment:

I was under the impression the annotations was only needed when the referenced class was a sub-class.

No, they are also needed when not declared in the JAXB context or, for example, when the only class having a static reference to it has this reference annotated with @XmlTransient. I maintain a tutorial here.

Your part:

$result = mysql_connect("localhost", "******", "*****") or die ("Could not save image name

Error: " . mysql_error());

mysql_select_db("project") or die("Could not select database");
mysql_query("INSERT into dbProfiles (photo) VALUES('".$_FILES['filep']['name']."')");
if($result) { echo "Image name saved into database

";

Doesn't make much sense, your connection shouldn't be named $result but that is a naming issue not a coding one.

What is a coding issue is if($result), your saying if you can connect to the database regardless of the insert query failing or succeeding you will output "Image saved into database".

Try adding do

$realresult = mysql_query("INSERT into dbProfiles (photo) VALUES('".$_FILES['filep']['name']."')");

and change the if($result) to $realresult

I suspect your query is failing, perhaps you have additional columns or something?

Try copy/pasting your query, replacing the ".$_FILES['filep']['name']." with test and running it in your query browser and see if it goes in.

There is no variable included for that yet, so you have to use shell-out-read-file method:

sh 'pwd > workspace'
workspace = readFile('workspace').trim()

Or (if running on master node):

workspace = pwd()

I think you are confusing objects and classes. A class inside a class looks like this:

class Foo(object):
    class Bar(object):
        pass

>>> foo = Foo()
>>> bar = Foo.Bar()

But it doesn't look to me like that's what you want. Perhaps you are after a simple containment hierarchy:

class Player(object):
    def __init__(self, ... airplanes ...) # airplanes is a list of Airplane objects
        ...
        self.airplanes = airplanes
        ...

class Airplane(object):
    def __init__(self, ... flights ...) # flights is a list of Flight objects
        ...
        self.flights = flights
        ...

class Flight(object):
    def __init__(self, ... duration ...)
        ...
        self.duration = duration
        ...

Then you can build and use the objects thus:

player = Player(...[
    Airplane(... [
        Flight(...duration=10...),
        Flight(...duration=15...),
        ] ... ),
    Airplane(...[
        Flight(...duration=20...),
        Flight(...duration=11...),
        Flight(...duration=25...),

To add disabled attribute

$('#id').attr("disabled", "true");

To remove Disabled Attribute

$('#id').removeAttr('disabled');

A stub is a controllable replacement for an Existing Dependency (or collaborator) in the system. By using a stub, you can test your code without dealing with the dependency directly.

External Dependency - Existing Dependency:
It is an object in your system that your code under test interacts with and over which you have no control. (Common examples are filesystems, threads, memory, time, and so on.)

Forexample in below code:

public void Analyze(string filename)
    {
        if(filename.Length<8)
        {
            try
            {
                errorService.LogError("long file entered named:" + filename);
            }
            catch (Exception e)
            {
                mailService.SendEMail("[email protected]", "ErrorOnWebService", "someerror");
            }
        }
    }

You want to test mailService.SendEMail() method, but to do that you need to simulate an Exception in your test method, so you just need to create a Fake Stub errorService object to simulate the result you want, then your test code will be able to test mailService.SendEMail() method. As you see you need to simulate a result which is from an another Dependency which is ErrorService class object (Existing Dependency object).

The best solution above faces a problem when using the same associative keys, array_merge() will merge array elements together when they have the same NON-NUMBER key, so it is not suitable for the following case

$a1=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow");
$a2=array("c"=>"red","d"=>"black","e"=>"green");

If you are able output your value to the keys of your arrays instead (e.g ->pluck('name', 'id')->toArray() in Eloquent), you can use the following merge method instead

array_keys(array_merge($a1, $a2))

Basically what the code does is it utilized the behavior of array_merge() to get rid of duplicated keys and return you a new array with keys as array elements, hope it helps

If you have a module with a class you want to import, you can do it like this.

module = __import__(filename)
instance = module.MyClass()

If you do not know what the class is named, you can iterate through the classes available from a module.

import inspect
module = __import__(filename)
for c in module.__dict__.values():
    if inspect.isclass(c):
        # You may need do some additional checking to ensure 
        # it's the class you want
        instance = c()

I think the easiest way to match the characters like

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

The best way to do it on blur is:

                        function formatPhone(obj) {
                        if (obj.value != "")
                        { 
                            var numbers = obj.value.replace(/\D/g, ''),
                            char = {0:'(',3:') ',6:' - '};
                            obj.value = '';
                            upto = numbers.length; 

                            if(numbers.length < 10) 
                            { 
                                upto = numbers.length; 
                            }
                            else
                            { 
                                upto = 10; 
                            }
                            for (var i = 0; i < upto; i++) {
                                obj.value += (char[i]||'') + numbers[i];
                            }
                        } 
                    }

It's just a 'safety' warning. It is a relatively common idiom, but also a relatively common error when you meant to have == in there. You can make the warning go away by adding another set of parentheses:

while ((list = list->next))

I forget where I saw this definition, but I think it's pretty nice.

A library is a module that you call from your code, and a framework is a module which calls your code.

If your project (PrjTest) does not expose any public types within the PrjTest namespace, it will cause that error.

Does the project (PrjTest) include any classes or types in the "PrjTest" namespace which are public?

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

Try this...

I have used following code to read "xls and xlsx"

    <?php
    include 'excel_reader.php';       // include the class
    $excel = new PhpExcelReader;      // creates object instance of the class
    $excel->read('excel_file.xls');   // reads and stores the excel file data

    // Test to see the excel data stored in $sheets property
    echo '<pre>';
    var_export($excel->sheets);

    echo '</pre>';

    or 

 echo '<pre>';
    print_r($excel->sheets);

    echo '</pre>';

The default behaviour of Newtonsoft.Json is going to find the public constructors. If your default constructor is only used in containing class or the same assembly, you can reduce the access level to protected or internal so that Newtonsoft.Json will pick your desired public constructor.

Admittedly, this solution is rather very limited to specific cases.

internal Result() { }

public Result(int? code, string format, Dictionary<string, string> details = null)
{
    Code = code ?? ERROR_CODE;
    Format = format;

    if (details == null)
        Details = new Dictionary<string, string>();
    else
        Details = details;
}

1) Find out where java is installed on your drive, open a cmd prompt, go to that location and run ".\java -version" to find out the exact version. Or, quite simply, check the add/remove module in the control panel.

2) After you actually install jdk 7, you need to tell Eclipse about it. Window -> Preferences -> Java -> Installed JREs.

From Auth0.com

Token-Based Authentication, relies on a signed token that is sent to the server on each request.

What are the benefits of using a token-based approach?

• Cross-domain / CORS: cookies + CORS don't play well across different domains. A token-based approach allows you to make AJAX calls to any server, on any domain because you use an HTTP header to transmit the user information.

• Stateless (a.k.a. Server side scalability): there is no need to keep a session store, the token is a self-contained entity that conveys all the user information. The rest of the state lives in cookies or local storage on the client side.

• CDN: you can serve all the assets of your app from a CDN (e.g. javascript, HTML, images, etc.), and your server side is just the API.

• Decoupling: you are not tied to any particular authentication scheme. The token might be generated anywhere, hence your API can be called from anywhere with a single way of authenticating those calls.

• Mobile ready: when you start working on a native platform (iOS, Android, Windows 8, etc.) cookies are not ideal when consuming a token-based approach simplifies this a lot.

• CSRF: since you are not relying on cookies, you don't need to protect against cross site requests (e.g. it would not be possible to sib your site, generate a POST request and re-use the existing authentication cookie because there will be none).

• Performance: we are not presenting any hard perf benchmarks here, but a network roundtrip (e.g. finding a session on database) is likely to take more time than calculating an HMACSHA256 to validate a token and parsing its contents.

<img src='thumb.gif' onclick='this.src="full_size.gif"' />

Of course you can change the onclick event to load the image wherever you want.

Personally, I would use XSLT to transform the XML and remove the trailing colons. For example, suppose I have this input:

<?xml version="1.0" encoding="UTF-8"?>
<Document>
    <Paragraph>This paragraph ends in a period.</Paragraph>
    <Paragraph>This one ends in a colon:</Paragraph>
    <Paragraph>This one has a : in the middle.</Paragraph>
</Document>

If I wanted to strip out trailing colons in my paragraphs, I would use this XSLT:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:fn="http://www.w3.org/2005/xpath-functions"
    version="2.0">
    <!-- identity -->
    <xsl:template match="/|@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <!-- strip out colons at the end of paragraphs -->
    <xsl:template match="Paragraph">
        <xsl:choose>
            <!-- if it ends with a : -->
            <xsl:when test="fn:ends-with(.,':')">
                <xsl:copy>
                    <!-- copy everything but the last character -->
                    <xsl:value-of select="substring(., 1, string-length(.)-1)"></xsl:value-of>
                </xsl:copy>
            </xsl:when>
            <xsl:otherwise>
                <xsl:copy>
                    <xsl:apply-templates/>
                </xsl:copy>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
</xsl:stylesheet> 

Most of the times these terms Web Server and Application server are used interchangeably.

Following are some of the key differences in features of Web Server and Application Server:

• Web Server is designed to serve HTTP Content. App Server can also serve HTTP Content but is not limited to just HTTP. It can be provided other protocol support such as RMI/RPC
• Web Server is mostly designed to serve static content, though most Web Servers have plugins to support scripting languages like Perl, PHP, ASP, JSP etc. through which these servers can generate dynamic HTTP content.
• Most of the application servers have Web Server as integral part of them, that means App Server can do whatever Web Server is capable of. Additionally App Server have components and features to support Application level services such as Connection Pooling, Object Pooling, Transaction Support, Messaging services etc.
• As web servers are well suited for static content and app servers for dynamic content, most of the production environments have web server acting as reverse proxy to app server. That means while servicing a page request, static contents (such as images/Static HTML) are served by web server that interprets the request. Using some kind of filtering technique (mostly extension of requested resource) web server identifies dynamic content request and transparently forwards to app server

Example of such configuration is Apache Tomcat HTTP Server and Oracle (formerly BEA) WebLogic Server. Apache Tomcat HTTP Server is Web Server and Oracle WebLogic is Application Server.

In some cases the servers are tightly integrated such as IIS and .NET Runtime. IIS is web server. When equipped with .NET runtime environment, IIS is capable of providing application services.

You can use rfind() or rindex()
^{Python2 links: rfind() rindex()}

>>> s = 'Hello StackOverflow Hi everybody'

>>> print( s.rfind('H') )
20

>>> print( s.rindex('H') )
20

>>> print( s.rfind('other') )
-1

>>> print( s.rindex('other') )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: substring not found

The difference is when the substring is not found, rfind() returns -1 while rindex() raises an exception ValueError (Python2 link: ValueError).

If you do not want to check the rfind() return code -1, you may prefer rindex() that will provide an understandable error message. Else you may search for minutes where the unexpected value -1 is coming from within your code...

Example: Search of last newline character

>>> txt = '''first line
... second line
... third line'''

>>> txt.rfind('\n')
22

>>> txt.rindex('\n')
22

The javadoc for Object specifies that

This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.

If a class overrides hashCode, it means that it wants to generate a specific id, which will (one can hope) have the right behaviour.

You can use System.identityHashCode to get that id for any class.

You want to join on condition 1 AND condition 2, so simply use the AND keyword as below

ON a.userid = b.sourceid AND a.listid = b.destinationid;

This worked really well for me....

// disable scrolling
$('body').bind('mousewheel touchmove', lockScroll);

// enable scrolling
$('body').unbind('mousewheel touchmove', lockScroll);


// lock window scrolling
function lockScroll(e) {
    e.preventDefault();
}

just wrap those two lines of code with whatever decides when you are going to lock scrolling.

e.g.

$('button').on('click', function() {
     $('body').bind('mousewheel touchmove', lockScroll);
});

In windows for me it kept saying "id_ed25135: No such file or directory" upon entering above commands. So I went to the folder, copied the path within folder explorer and added "\id_ed25135" at the end.

This is what I ended up typing and worked:
ssh-keygen -p -f C:\Users\john\.ssh\id_ed25135

This worked. Because for some reason, in Cmder the default path was something like this C:\Users\capit/.ssh/id_ed25135 (some were backslashes: "\" and some were forward slashes: "/")

File FileOne.js:

module.exports = { ClientIDUnsplash : 'SuperSecretKey' };

File FileTwo.js:

var { ClientIDUnsplash } = require('./FileOne');

This example works best for React.

You could wrapping the transaction over try..catch or even reverse them, here my example code I used to in laravel 5,, if you look deep inside DB:transaction() in Illuminate\Database\Connection that the same like you write manual transaction.

Laravel Transaction

public function transaction(Closure $callback)
    {
        $this->beginTransaction();

        try {
            $result = $callback($this);

            $this->commit();
        }

        catch (Exception $e) {
            $this->rollBack();

            throw $e;
        } catch (Throwable $e) {
            $this->rollBack();

            throw $e;
        }

        return $result;
    }

so you could write your code like this, and handle your exception like throw message back into your form via flash or redirect to another page. REMEMBER return inside closure is returned in transaction() so if you return redirect()->back() it won't redirect immediately, because the it returned at variable which handle the transaction.

Wrap Transaction

$result = DB::transaction(function () use ($request, $message) {
   try{

      // execute query 1
      // execute query 2
      // ..

      return redirect(route('account.article'));

   } catch (\Exception $e) {
       return redirect()->back()->withErrors(['error' => $e->getMessage()]);
    }
 });

// redirect the page
return $result;

then the alternative is throw boolean variable and handle redirect outside transaction function or if your need to retrieve why transaction failed you can get it from $e->getMessage() inside catch(Exception $e){...}

Let's break down the full URL that a client would type into their address bar to reach your servlet:

http://www.example.com:80/awesome-application/path/to/servlet/path/info?a=1&b=2#boo

The parts are:

1. scheme: http
2. hostname: www.example.com
3. port: 80
4. context path: awesome-application
5. servlet path: path/to/servlet
6. path info: path/info
7. query: a=1&b=2
8. fragment: boo

The request URI (returned by getRequestURI) corresponds to parts 4, 5 and 6.

(incidentally, even though you're not asking for this, the method getRequestURL would give you parts 1, 2, 3, 4, 5 and 6).

Now:

• part 4 (the context path) is used to select your particular application out of many other applications that may be running in the server
• part 5 (the servlet path) is used to select a particular servlet out of many other servlets that may be bundled in your application's WAR
• part 6 (the path info) is interpreted by your servlet's logic (e.g. it may point to some resource controlled by your servlet).
• part 7 (the query) is also made available to your servlet using getQueryString
• part 8 (the fragment) is not even sent to the server and is relevant and known only to the client

The following always holds (except for URL encoding differences):

requestURI = contextPath + servletPath + pathInfo

The following example from the Servlet 3.0 specification is very helpful:

Note: image follows, I don't have the time to recreate in HTML:

Also register your created service in the Manifest and uses-permission as

<application ...>
   <service android:name=".MyBroadcastReceiver">
        <intent-filter>
            <action android:name="com.example.MyBroadcastReciver"/>
        </intent-filter>
   </service>
</application>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

and then in braod cast Reciever call your service

public class MyBroadcastReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Intent myIntent = new Intent(context, MyService.class);
        context.startService(myIntent);
    }
}

I needed to indent two rows to allow for a larger first word in a para. A cumbersome one-off solution is to place text in an SVG element and position this the same as an <img>. Using float and the SVG's height tag defines how many rows will be indented e.g.

<p style="color: blue; font-size: large; padding-top: 4px;">
<svg height="44" width="260" style="float:left;margin-top:-8px;"><text x="0" y="36" fill="blue" font-family="Verdana" font-size="36">Lorum Ipsum</text></svg> 
dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.</p>

• SVG's height and width determine area blocked out.
• Y=36 is the depth to the SVG text baseline and same as font-size
• margin-top's allow for best alignment of the SVG text and para text
• Used first two words here to remind care needed for descenders

Yes it is cumbersome but it is also independent of the width of the containing div.

The above answer was to my own query to allow the first word(s) of a para to be larger and positioned over two rows. To simply indent the first two lines of a para you could replace all the SVG tags with the following single pixel img:

<img src="data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" style="float:left;width:260px;height:44px;" />

With Ramda, you can simply do R.isNil(yourValue) Lodash and other helper libraries have the same function.

The essential idea here is to select the data you want to sum, and then sum them. This selection of data can be done in several different ways, a few of which are shown below.

Boolean indexing

Arguably the most common way to select the values is to use Boolean indexing.

With this method, you find out where column 'a' is equal to 1 and then sum the corresponding rows of column 'b'. You can use loc to handle the indexing of rows and columns:

>>> df.loc[df['a'] == 1, 'b'].sum()
15

The Boolean indexing can be extended to other columns. For example if df also contained a column 'c' and we wanted to sum the rows in 'b' where 'a' was 1 and 'c' was 2, we'd write:

df.loc[(df['a'] == 1) & (df['c'] == 2), 'b'].sum()

Query

Another way to select the data is to use query to filter the rows you're interested in, select column 'b' and then sum:

>>> df.query("a == 1")['b'].sum()
15

Again, the method can be extended to make more complicated selections of the data:

df.query("a == 1 and c == 2")['b'].sum()

Note this is a little more concise than the Boolean indexing approach.

Groupby

The alternative approach is to use groupby to split the DataFrame into parts according to the value in column 'a'. You can then sum each part and pull out the value that the 1s added up to:

>>> df.groupby('a')['b'].sum()[1]
15

This approach is likely to be slower than using Boolean indexing, but it is useful if you want check the sums for other values in column a:

>>> df.groupby('a')['b'].sum()
a
1    15
2     8

Why not use a simpler approach? Add a class!

Simply add a class that tells the interval not to do anything. For example: on hover.

var i = 0;_x000D_
this.setInterval(function() {_x000D_
  if(!$('#counter').hasClass('pauseInterval')) { //only run if it hasn't got this class 'pauseInterval'_x000D_
    console.log('Counting...');_x000D_
    $('#counter').html(i++); //just for explaining and showing_x000D_
  } else {_x000D_
    console.log('Stopped counting');_x000D_
  }_x000D_
}, 500);_x000D_
_x000D_
/* In this example, I'm adding a class on mouseover and remove it again on mouseleave. You can of course do pretty much whatever you like */_x000D_
$('#counter').hover(function() { //mouse enter_x000D_
    $(this).addClass('pauseInterval');_x000D_
  },function() { //mouse leave_x000D_
    $(this).removeClass('pauseInterval');_x000D_
  }_x000D_
);_x000D_
_x000D_
/* Other example */_x000D_
$('#pauseInterval').click(function() {_x000D_
  $('#counter').toggleClass('pauseInterval');_x000D_
});

body {_x000D_
  background-color: #eee;_x000D_
  font-family: Calibri, Arial, sans-serif;_x000D_
}_x000D_
#counter {_x000D_
  width: 50%;_x000D_
  background: #ddd;_x000D_
  border: 2px solid #009afd;_x000D_
  border-radius: 5px;_x000D_
  padding: 5px;_x000D_
  text-align: center;_x000D_
  transition: .3s;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
#counter.pauseInterval {_x000D_
  border-color: red;  _x000D_
}

<!-- you'll need jQuery for this. If you really want a vanilla version, ask -->_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

<button id="pauseInterval">Pause</button></p>

I've been looking for this fast and easy approach for ages, so I'm posting several versions to introduce as many people to it as possible.

You can add a UITapGestureRecognizer to the imageView, just drag one into your Storyboard/xib, Ctrl-drag from the imageView to the gestureRecognizer, and Ctrl-drag from the gestureRecognizer to the Swift-file to make an IBAction.

You'll also need to enable user interactions on the UIImageView, as shown in this image:

I do not know much about Java but URL query arguments should be separated by "&", not "?"

http://tools.ietf.org/html/rfc3986 is good place for reference using "sub-delim" as keyword. http://en.wikipedia.org/wiki/Query_string is another good source.

You could start by using git merge --no-commit, and then edit the merge however you like i.e. by unstaging config.xml or any other file, then commit. I suspect you'd want to automate it further after that using hooks, but I think it'd be worth going through manually at least once.

Dirty way to find running services. (sometime it is not accurate because some custom script doesn't have |status| option)

[root@server ~]# for qw in `ls /etc/init.d/*`; do  $qw status | grep -i running; done

  var json = {"ListID" : "1", "ItemName":"test"};
    $.ajax({
            url: url,
            type: 'POST',        
            data: username, 
            cache:false,
            beforeSend: function(xhr) {  
                xhr.setRequestHeader("Accept", "application/json");  
                xhr.setRequestHeader("Content-Type", "application/json");  
            },       
            success:function(response){
             console.log("Success")
            },
              error : function(xhr, status, error) {
            console.log("error")
            }
);

A more straight forward way is to check for equality

if string1 == string2
  puts "match"
else
  puts "not match"
end

however, if you really want to stick to regular expression,

string1 =~ /^123456$/

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    if([text isEqualToString:@"\n"])
        [textView resignFirstResponder];
    return YES;
}

yourtextView.delegate=self;

Also add UITextViewDelegate

Don't forget to confirm protocol

IF you didn't add if([text isEqualToString:@"\n"]) you can't edit

If you make

overflow: hidden in the outer div and overflow-y: scroll in the inner div it will work.

http://jsfiddle.net/C8MuZ/11/

That will only work if register_globals is on, and it should never be on (unless of course you are defining that variable somewhere else).

Try setting the form's action attribute to ?...

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

You can also set it to be blank (""), but older WebKit versions had a bug.

s is an uninitialized pointer; you are writing to a random location in memory. This will invoke undefined behaviour.

You need to allocate some memory for s. Also, never use gets; there is no way to prevent it overflowing the memory you allocate. Use fgets instead.

Try this:

counter=0
while true; do
  if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
       echo "Files Present" | mailx -s "File Present"  -r [email protected] [email protected]
       break
  elif [[ "$counter" -gt 20 ]]; then
       echo "Counter limit reached, exit script."
       exit 1
  else
       let counter++
       echo "Sleeping for another half an hour" | mailx -s "Time to Sleep Now"  -r [email protected] [email protected]
       sleep 1800
  fi
done

Explanation

• break - if files are present, it will break and allow the script to process the files.
• [[ "$counter" -gt 20 ]] - if the counter variable is greater than 20, the script will exit.
• let counter++ - increments the counter by 1 at each pass.

In 2012 OData underwent standardization, so I'll just add an update here..

First the definitions:

REST - is an architecture of how to send messages over HTTP.

OData V4- is a specific implementation of REST, really defines the content of the messages in different formats (currently I think is AtomPub and JSON). ODataV4 follows rest principles.

For example, asp.net people will mostly use WebApi controller to serialize/deserialize objects into JSON and have javascript do something with it. The point of Odata is being able to query directly from the URL with out-of-the-box options.

There's a far more simpler solution to tackle this.

The reason why you get ValueError: Index contains duplicate entries, cannot reshape is because, once you unstack "Location", then the remaining index columns "id" and "date" combinations are no longer unique.

You can avoid this by retaining the default index column (row #) and while setting the index using "id", "date" and "location", add it in "append" mode instead of the default overwrite mode.

So use,

e.set_index(['id', 'date', 'location'], append=True)

Once this is done, your index columns will still have the default index along with the set indexes. And unstack will work.

Let me know how it works out.

It's time to add some lambdas:

codes.entrySet()
    .stream()
    .sorted(Comparator.comparing(Map.Entry::getValue))
    .forEach(System.out::println);

According to the latest Apple Human Interface Guidelines:

In portrait orientation, tab bar icons appear above tab titles. In landscape orientation, the icons and titles appear side-by-side. Depending on the device and orientation, the system displays either a regular or compact tab bar. Your app should include custom tab bar icons for both sizes.

I suggest you to use the above link to understand the full concept. Because apple update it's document in regular interval

I really liked @brettdj's code, but then I found that when I added additional code to edit the copy, it overwrote my original sheet instead. I've tweaked his answer so that further code pointed at ws1 will affect the new sheet rather than the original.

Sub Test()
    Dim ws1 as Worksheet
    ThisWorkbook.Worksheets("Master").Copy
    Set ws1 = ThisWorkbook.Worksheets("Master (2)")
End Sub

You can always, reshape like:

temp = [1,2,3,4,5,5,6,7]

temp = temp.reshape(len(temp), 1)

Because, the major issue is when your, temp.shape is: (8,)

and you need (8,1)

I'm not a mathematician or cryptician, so here's an outside observation in layman's terms (no fancy equations, sorry).

This whole thread is filled with explanations about HOW primes are used in cryptography, it's hard to find anyone in this thread explaining in an easy way WHY primes are used ... most likely because everyone takes that knowledge for granted.

Only looking at the problem from the outside can generate a reaction like; but if they use the sums of two primes, why not create a list of all possible sums any two primes can generate?

On this site there's a list of 455,042,511 primes, where the highest primes is 9,987,500,000 (10 digits).

The largest known prime (as of feb 2015) is 2 to the power of 257,885,161 - 1 which is 17,425,170 digits.

This means that there's no point keeping a list of all the known primes and much less all their possible sums. It's easier to take a number and check if it's a prime.

Calculating big primes in itself is a monumental task, so reverse calculating two primes that has been multiplied with each other both cryptographers and mathematicians would say is hard enough ... today.

It was bothering me that implementing a listener for all of my EditText fields required me to have ugly, verbose code so I wrote the below class. May be useful to anyone stumbling upon this.

public abstract class TextChangedListener<T> implements TextWatcher {
    private T target;

    public TextChangedListener(T target) {
        this.target = target;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}

    @Override
    public void afterTextChanged(Editable s) {
        this.onTextChanged(target, s);
    }

    public abstract void onTextChanged(T target, Editable s);
}

Now implementing a listener is a little bit cleaner.

editText.addTextChangedListener(new TextChangedListener<EditText>(editText) {
            @Override
            public void onTextChanged(EditText target, Editable s) {
                //Do stuff
            }
        });

As for how often it fires, one could maybe implement a check to run their desired code in //Do stuff after a given a

Looping the pointer to gain better performance:

#include <ctype.h>

char* toLower(char* s) {
  for(char *p=s; *p; p++) *p=tolower(*p);
  return s;
}
char* toUpper(char* s) {
  for(char *p=s; *p; p++) *p=toupper(*p);
  return s;
}

The common error that I have find is when you forget to define your url in yourapp/urls.py

we don't want any suggetion!! solution plz..

You need to declare y and c outside the scope of the if/else statement. A variable is only valid inside the scope it is declared (and a scope is marked with { })

#include <iostream> 
using namespace std; 
//Using the Gaussian algorithm 
int dayofweek(int date, int month, int year ){ 
int d=date; 
int y, c;
if (month==1||month==2) 
        {y=((year-1)%100);c=(year-1)/100;} 
else 
        {y=year%100;c=year/100;} 
int m=(month+9)%12+1; 
int product=(d+(2.6*m-0.2)+y+y/4+c/4-2*c); 
return product%7; 
} 

int main(){ 
cout<<dayofweek(19,1,2054); 
return 0; 
} 

Just adding a default custom WebViewClient will do. This makes the WebView handle any loaded urls itself.

mWebView.setWebViewClient(new WebViewClient());

You might also try eliminating the code you think you're having problems with and seeing if it compiles with no references to that code. If not, fix things until it compiles again, and then work your suspected problem code back in. Sometimes I get strange errors about classes or methods that I know are correct when the compiler doesn't like something else. Once I fix the thing that it's really getting hung up on, these 'phantom' errors disappear.

What about something like this:

for /f %%f in ('curl -s -l -u user:pass ftp://ftp.myftpsite.com/') do curl -O -u user:pass ftp://ftp.myftpsite.com/%%f

Just edit the httpd-vhost-conf scroll to the bottom and on the last example/demo for creating a virtual host, remove the hash-tags for DocumentRoot and ServerName. You may have hash-tags just before the <VirtualHost *.80> and </VirtualHost>

After DocumentRoot, just add the path to your web-docs ... and add your domain-name after ServerNmane

<VirtualHost *:80>
    ##ServerAdmin [email protected]
    DocumentRoot "C:/xampp/htdocs/www"
    ServerName example.com
    ##ErrorLog "logs/dummy-host2.example.com-error.log"
    ##CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>

Be sure to create the www folder under htdocs. You do not have to name the folder www but I did just to be simple about it. Be sure to restart Apache and bang! you can now store files in the newly created directory. To test things out just create a simple index.html or index.php file and place in the www folder, then go to your browser and test it out localhost/ ... Note: if your server is serving php files over html then remember to add localhost/index.html if the html file is the one you choose to use for this test.

Something I should add, in order to still have access to the xampp homepage then you will need to create another VirtualHost. To do this just add

<VirtualHost *:80>
    ##ServerAdmin [email protected]
    DocumentRoot "C:/xampp/htdocs"
    ServerName htdocs.example.com
    ##ErrorLog "logs/dummy-host2.example.com-error.log"
    ##CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>

underneath the last VirtualHost that you created. Next make the necessary changes to your host file and restart Apache. Now go to your browser and visit htdocs.example.com and your all set.

Check this SharpDOM . This is a c# 4.0 internal dsl for generating html and also asp.net mvc view engine.

Change the window name in your two different calls:

function popitup(url,windowName) {
       newwindow=window.open(url,windowName,'height=200,width=150');
       if (window.focus) {newwindow.focus()}
       return false;
     }

windowName must be unique when you open a new window with same url otherwise the same window will be refreshed.

From the comments:

import msvcrt # built-in module

def kbfunc():
    return ord(msvcrt.getch()) if msvcrt.kbhit() else 0

Thanks for the help. I ended up writing a C DLL called PyKeyboardAccess.dll and accessing the crt conio functions, exporting this routine:

#include <conio.h>

int kb_inkey () {
   int rc;
   int key;

   key = _kbhit();

   if (key == 0) {
      rc = 0;
   } else {
      rc = _getch();
   }

   return rc;
}

And I access it in python using the ctypes module (built into python 2.5):

import ctypes
import time

#
# first, load the DLL
#


try:
    kblib = ctypes.CDLL("PyKeyboardAccess.dll")
except:
    raise ("Error Loading PyKeyboardAccess.dll")


#
# now, find our function
#

try:
    kbfunc = kblib.kb_inkey
except:
    raise ("Could not find the kb_inkey function in the dll!")


#
# Ok, now let's demo the capability
#

while 1:
    x = kbfunc()

    if x != 0:
        print "Got key: %d" % x
    else:
        time.sleep(.01)

There is a specific property for this. It is called CharacterCasing and you could set it to Upper

  TextBox1.CharacterCasing = CharacterCasing.Upper;

In ASP.NET you could try to add this to your textbox style

  style="text-transform:uppercase;"

You could find an example here: http://www.w3schools.com/cssref/pr_text_text-transform.asp

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

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

The CONTAINS query should be:

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

Use the background-color property instead of the background property in your CSS. So your code will look like this:
.fb-icon:hover {
background: blue;
}

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("C:\\");
    }
}

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

FWIW, I was getting this error when I was accidentally making a GET request to an endpoint that was expecting a POST request. Presumably that was just that particular servers way of handling the problem.

tl;dr

Data structures (DS) are important because they are used to perform operations on data which basically implies: take some input, process it, and give back the output.

Some data structures are more useful than others in some particular cases. Therefore, it is quite unfair to ask which (DS) is more efficient/speedy. It is like asking which tool is more efficient between a knife and fork. I mean all depends on the situation.

Lists

A list is mutable sequence, typically used to store collections of homogeneous items.

Sets

A set object is an unordered collection of distinct hashable objects. It is commonly used to test membership, remove duplicates from a sequence, and compute mathematical operations such as intersection, union, difference, and symmetric difference.

Usage

From some of the answers, it is clear that a list is quite faster than a set when iterating over the values. On the other hand, a set is faster than a list when checking if an item is contained within it. Therefore, the only thing you can say is that a list is better than a set for some particular operations and vice-versa.

Some dtype are not supported by specific OpenCV functions. For example inputs of dtype np.uint32 create this error. Try to convert the input to a supported dtype (e.g. np.int32 or np.float32)

1 You can use a drawable

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_item1"
        android:icon="@drawable/my_item_drawable"
        android:title="@string/menu_item1"
        android:showAsAction="ifRoom" />
</menu>

2 Create a style for the action bar and use a custom background:

<resources>
    <!-- the theme applied to the application or activity -->
    <style name="CustomActivityTheme" parent="@android:style/Theme.Holo">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
        <!-- other activity and action bar styles here -->
    </style>
    <!-- style for the action bar backgrounds -->
    <style name="MyActionBar" parent="@android:style/Widget.Holo.ActionBar">
        <item name="android:background">@drawable/background</item>
        <item name="android:backgroundStacked">@drawable/background</item>
        <item name="android:backgroundSplit">@drawable/split_background</item>
    </style>
</resources>

3 Style again android:actionBarDivider

The android documentation is very usefull for that.

After spending about two hours trying to come up with a solution I realized that I had adblockers blocking the call to GA. Once I turned them off I was good to go.

In the interest of creating a simple example that uses const...

const myRef = { foo: 'bar' };
const myVal = true;

function passes(r, v) {
  r.foo = 'baz';
  v = false;
}

passes(myRef, myVal);

console.log(myRef, myVal); // Object {foo: "baz"} true

I know I am posting this answer little late, but I felt it is worth using Google's fuse location provider service to get the current location.

Main features of this api are :

1.Simple APIs: Lets you choose your accuracy level as well as power consumption.

2.Immediately available: Gives your apps immediate access to the best, most recent location.

3.Power-efficiency: It chooses the most efficient way to get the location with less power consumptions

4.Versatility: Meets a wide range of needs, from foreground uses that need highly accurate location to background uses that need periodic location updates with negligible power impact.

It is flexible in while updating in location also. If you want current location only when your app starts then you can use getLastLocation(GoogleApiClient) method.

If you want to update your location continuously then you can use requestLocationUpdates(GoogleApiClient,LocationRequest, LocationListener)

You can find a very nice blog about fuse location here and google doc for fuse location also can be found here.

Update

According to developer docs starting from Android O they have added new limits on background location.

If your app is running in the background, the location system service computes a new location for your app only a few times each hour. This is the case even when your app is requesting more frequent location updates. However if your app is running in the foreground, there is no change in location sampling rates compared to Android 7.1.1 (API level 25).

Once you have localized the dropdown element

dropdownElement = $("#dropdownElement");

Find the <option> element using the JQuery attribute selector

dropdownElement.find('option[value=foo]').remove();

The second form (creating an HTTP server yourself, instead of having Express create one for you) is useful if you want to reuse the HTTP server, for example to run socket.io within the same HTTP server instance:

var express = require('express');
var app     = express();
var server  = require('http').createServer(app);
var io      = require('socket.io').listen(server);
...
server.listen(1234);

However, app.listen() also returns the HTTP server instance, so with a bit of rewriting you can achieve something similar without creating an HTTP server yourself:

var express   = require('express');
var app       = express();

// app.use/routes/etc...

var server    = app.listen(3033);
var io        = require('socket.io').listen(server);

io.sockets.on('connection', function (socket) {
  ...
});

  #!/bin.bash
for folder_to_go in $(find . -mindepth 1 -maxdepth 1 -type d \( -name "*" \) ) ; 
                                    # you can add pattern insted of * , here it goes to any folder 
                                    #-mindepth / maxdepth 1 means one folder depth   
do
cd $folder_to_go
  echo $folder_to_go "########################################## "
  
  whatever you want to do is here

cd ../ # if maxdepth/mindepath = 2,  cd ../../
done

#you can try adding many internal for loops with many patterns, this will sneak anywhere you want

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.

sudo apt-get install ruby-all-dev

worked for me.

If you have more than one view in the layout file android.R.layout.simple_list_item_1 then you'll have to pass the third argument android.R.id.text1 to specify the view that should be filled with the array elements (values). But if you have just one view in your layout file, there is no need to specify the third argument.

Here's how one can get the actual path to the file in MacOS/Unix using an inline Perl script:

FILE=$(perl -e "use Cwd qw(abs_path); print abs_path('$0')")

Similarly, to get the directory of a symlinked file:

DIR=$(perl -e "use Cwd qw(abs_path); use File::Basename; print dirname(abs_path('$0'))")

in continuation to @ Cuong Le's answer , my approach to prevent replay attack would be

// Encrypt the Unix Time at Client side using the shared private key(or user's password)

// Send it as part of request header to server(WEB API)

// Decrypt the Unix Time at Server(WEB API) using the shared private key(or user's password)

// Check the time difference between the Client's Unix Time and Server's Unix Time, should not be greater than x sec

// if User ID/Hash Password are correct and the decrypted UnixTime is within x sec of server time then it is a valid request

Maybe you are out of inodes. Try df -i

                     2591792  136322 2455470    6% /home
/dev/sdb1            1887488 1887488       0  100% /data

Disk used 6% but inode table full.

Sounds like you're expecting size_t to be the same as unsigned long (possibly 64 bits) when it's actually an unsigned int (32 bits). Try using %zu in both cases.

I'm not entirely certain though.

There's actually a good reason:
The non-static access does not always work, for reasons of ambiguity.

Suppose we have two classes, A and B, the latter being a subclass of A, with static fields with the same name:

public class A {
    public static String VALUE = "Aaa";
}

public class B extends A {
    public static String VALUE = "Bbb";
}

Direct access to the static variable:

A.VALUE (="Aaa")
B.VALUE (="Bbb")

Indirect access using an instance (gives a compiler warning that VALUE should be statically accessed):

new B().VALUE (="Bbb")

So far, so good, the compiler can guess which static variable to use, the one on the superclass is somehow farther away, seems somehow logical.

Now to the point where it gets tricky: Interfaces can also have static variables.

public interface C {
    public static String VALUE = "Ccc";
}

public interface D {
    public static String VALUE = "Ddd";
}

Let's remove the static variable from B, and observe following situations:

• B implements C, D
• B extends A implements C
• B extends A implements C, D
• B extends A implements C where A implements D
• B extends A implements C where C extends D
• ...

The statement new B().VALUE is now ambiguous, as the compiler cannot decide which static variable was meant, and will report it as an error:

error: reference to VALUE is ambiguous
both variable VALUE in C and variable VALUE in D match

And that's exactly the reason why static variables should be accessed in a static way.

This is the conditional operator expression.

(condition) ? [true path] : [false path];

For example

 string value = someBooleanExpression ? "Alpha" : "Beta";

So if the boolean expression is true, value will hold "Alpha", otherwise, it holds "Beta".

for example I faced this in express node.js when trying to create route for paths not starting with /internal

app.get(`\/(?!internal).*`, (req, res)=>{

and after long trying it just worked when passing it as a RegExp Object using new RegExp()

app.get(new RegExp("\/(?!internal).*"), (req, res)=>{

this may help if you are getting this common issue in routing

I use something like this to load properties file.

        final ResourceBundle bundle = ResourceBundle
                .getBundle("properties/errormessages");

        for (final Enumeration<String> keys = bundle.getKeys(); keys
                .hasMoreElements();) {
            final String key = keys.nextElement();
            final String value = bundle.getString(key);
            prop.put(key, value);
        }

    font-size: 25px;

}

When you are using as syntax, like ParentController as parentCtrl, to define a controller then to access parent scope variable in child controller use following :

var id = $scope.parentCtrl.id;

Where parentCtrl is name of parent controller using as syntax and id is a variable defined in same controller.

Just use os.listdir and os.path.isfile instead of os.walk.

Example:

import os
files = [f for f in os.listdir('.') if os.path.isfile(f)]
for f in files:
    # do something

But be careful while applying this to other directory, like

files = [f for f in os.listdir(somedir) if os.path.isfile(f)].

which would not work because f is not a full path but relative to the current dir.

Therefore, for filtering on another directory, do os.path.isfile(os.path.join(somedir, f))

(Thanks Causality for the hint)

use the following

select sum(transaction_amount) from TransactionMaste
where Card_No = '123' and transaction_date = CONVERT(VARCHAR(10),GETDATE(),111)

or the following

select sum(transaction_amount) from TransactionMaste
where Card_No = '123' and transaction_date = CONVERT(VARCHAR(10), GETDATE(), 120)

If you need some es6 improvements not supported by Typescript, you can target es6 in your tsconfig and use Babel to convert your files in es5.

If you're talking about checking it out, you probably want the subversion itself. If you're interested in history, I'd use git-svn. If you want the real subversion clone, I don't know, there was something. :)

You may use the class java.util.Random with method

char c = (char)(rnd.nextInt(128-32))+32 

20x to get Bytes, which you interpret as ASCII. If you're fine with ASCII.

32 is the offset, from where the characters are printable in general.

What problem are you having, specifically?

Binary floating-point numbers have interesting precision characteristics, since the value is stored as a binary integer raised to a binary power. When dealing with sub-integer values (that is, values between 0 and 1), negative powers of two "round off" very differently than negative powers of ten.

For example, the number 0.1 can be represented by 1 x 10^-1, but there is no combination of base-2 exponent and mantissa that can precisely represent 0.1 -- the closest you get is 0.10000000000000001.

So if you have an application where you are working with values like 0.1 or 0.01 a great deal, but where small (less than 0.000000000000001%) errors cannot be tolerated, then binary floating-point numbers are not for you.

Conversely, if powers of ten are not "special" to your application (powers of ten are important in currency calculations, but not in, say, most applications of physics), then you are actually better off using binary floating-point, since it's usually at least an order of magnitude faster, and it is much more memory efficient.

The article from the Python documentation on floating point issues and limitations does an excellent job of explaining this issue in an easy to understand form. Wikipedia also has a good article on floating point that explains the math behind the representation.

you can do it with this

Cursor cursor = database.query(
            TABLE_NAME,
            YOUR_COLUMNS, null, null, null, null, COLUMN_INTEREST+" DESC");

While many people here say there is no best way for object creation, there is a rationale as to why there are so many ways to create objects in JavaScript, as of 2019, and this has to do with the progress of JavaScript over the different iterations of EcmaScript releases dating back to 1997.

Prior to ECMAScript 5, there were only two ways of creating objects: the constructor function or the literal notation ( a better alternative to new Object()). With the constructor function notation you create an object that can be instantiated into multiple instances (with the new keyword), while the literal notation delivers a single object, like a singleton.

// constructor function
function Person() {};

// literal notation
var Person = {};

Regardless of the method you use, JavaScript objects are simply properties of key value pairs:

// Method 1: dot notation
obj.firstName = 'Bob';

// Method 2: bracket notation. With bracket notation, you can use invalid characters for a javascript identifier.
obj['lastName'] = 'Smith';

// Method 3: Object.defineProperty
Object.defineProperty(obj, 'firstName', {
    value: 'Bob',
    writable: true,
    configurable: true,
    enumerable: false
})

// Method 4: Object.defineProperties
Object.defineProperties(obj, {
  firstName: {
    value: 'Bob',
    writable: true
  },
  lastName: {
    value: 'Smith',
    writable: false
  }
});

In early versions of JavaScript, the only real way to mimic class-based inheritance was to use constructor functions. the constructor function is a special function that is invoked with the 'new' keyword. By convention, the function identifier is capitalized, albiet it is not required. Inside of the constructor, we refer to the 'this' keyword to add properties to the object that the constructor function is implicitly creating. The constructor function implicitly returns the new object with the populated properties back to the calling function implicitly, unless you explicitly use the return keyword and return something else.

function Person(firstName, lastName) {
    this.firstName = firstName;
    this.lastName = lastName;

    this.sayName = function(){
        return "My name is " + this.firstName + " " + this.lastName;
    }
} 

var bob = new Person("Bob", "Smith");
bob instanceOf Person // true

There is a problem with the sayName method. Typically, in Object-Oriented Class-based programming languages, you use classes as factories to create objects. Each object will have its own instance variables, but it will have a pointer to the methods defined in the class blueprint. Unfortunately, when using JavaScript's constructor function, every time it is called, it will define a new sayName property on the newly created object. So each object will have its own unique sayName property. This will consume more memory resources.

In addition to increased memory resources, defining methods inside of the constructor function eliminates the possibility of inheritance. Again, the method will be defined as a property on the newly created object and no other object, so inheritance cannot work like. Hence, JavaScript provides the prototype chain as a form of inheritance, making JavaScript a prototypal language.

If you have a parent and a parent shares many properties of a child, then the child should inherit those properties. Prior to ES5, it was accomplished as follows:

function Parent(eyeColor, hairColor) {
    this.eyeColor = eyeColor;
    this.hairColor = hairColor;
}

Parent.prototype.getEyeColor = function() {
  console.log('has ' + this.eyeColor);
}

Parent.prototype.getHairColor = function() {
  console.log('has ' + this.hairColor);
}

function Child(firstName, lastName) {
  Parent.call(this, arguments[2], arguments[3]);
  this.firstName = firstName;
  this.lastName = lastName;
}

Child.prototype = Parent.prototype;

var child = new Child('Bob', 'Smith', 'blue', 'blonde');
child.getEyeColor(); // has blue eyes
child.getHairColor(); // has blonde hair

The way we utilized the prototype chain above has a quirk. Since the prototype is a live link, by changing the property of one object in the prototype chain, you'd be changing same property of another object as well. Obviously, changing a child's inherited method should not change the parent's method. Object.create resolved this issue by using a polyfill. Thus, with Object.create, you can safely modify a child's property in the prototype chain without affecting the parent's same property in the prototype chain.

ECMAScript 5 introduced Object.create to solve the aforementioned bug in the constructor function for object creation. The Object.create() method CREATES a new object, using an existing object as the prototype of the newly created object. Since a new object is created, you no longer have the issue where modifying the child property in the prototype chain will modify the parent's reference to that property in the chain.

var bobSmith = {
    firstName: "Bob",
    lastName: "Smith",
    sayName: function(){
      return "My name is " + this.firstName + " " + this.lastName;
    }
}

var janeSmith = Object.create(bobSmith, {
    firstName : {  value: "Jane" }
})

console.log(bobSmith.sayName()); // My name is Bob Smith
console.log(janeSmith.sayName()); // My name is Jane Smith
janeSmith.__proto__ == bobSmith; // true
janeSmith instanceof bobSmith; // Uncaught TypeError: Right-hand side of 'instanceof' is not callable. Error occurs because bobSmith is not a constructor function.

Prior to ES6, here was a common creational pattern to utilize function constructors and Object.create:

const View = function(element){
  this.element = element;
}

View.prototype = {
  getElement: function(){
    this.element
  }
}

const SubView = function(element){
  View.call(this, element);
}

SubView.prototype = Object.create(View.prototype);

Now Object.create coupled with constructor functions have been widely used for object creation and inheritance in JavaScript. However, ES6 introduced the concept of classes, which are primarily syntactical sugar over JavaScript's existing prototype-based inheritance. The class syntax does not introduce a new object-oriented inheritance model to JavaScript. Thus, JavaScript remains a prototypal language.

ES6 classes make inheritance much easier. We no longer have to manually copy the parent class's prototype functions and reset the child class's constructor.

// create parent class
class Person {
  constructor (name) {
    this.name = name;
  }
}

// create child class and extend our parent class
class Boy extends Person {
  constructor (name, color) {
    // invoke our parent constructor function passing in any required parameters
    super(name);

    this.favoriteColor = color;
  }
}

const boy = new Boy('bob', 'blue')
boy.favoriteColor; // blue

All in all, these 5 different strategies of Object Creation in JavaScript coincided the evolution of the EcmaScript standard.

The quickest fix for me was doing the following:

cd /usr/local
git reset --hard FETCH_HEAD

Then I retried brew install imagemagick and it correctly pulled the package from the new mirror, instead of adamv.

If that does not work, ensure that /Library/Caches/Homebrew does not contain any imagemagick files or folders. Delete them if it does.

I also hit this error. In my case the root cause was async related (during a codebase refactor): An asynchronous function that builds the object to which the "not a function" function belongs was not awaited, and the subsequent attempt to invoke the function throws the error, example below:

const car = carFactory.getCar();
car.drive() //throws TypeError: drive is not a function

The fix was:

const car = await carFactory.getCar();
car.drive()

Posting this incase it helps anyone else facing this error.

I'm running the very latest Laravel 5 dev release, and if you've changed the namespace you'll need to call your seed class like this:

$this->call('\todoparrot\TodolistTableSeeder');

Obviously you'll need to replace todoparrot with your designated namespace. Otherwise I receive the same error indicated in the original question.

It is not possible to add comments to 'normal' Access queries, that is, a QueryDef in an mdb, which is why a number of people recommend storing the sql for queries in a table.

Class.isAssignableFrom() - works for interfaces as well. If you don't want that, you'll have to call getSuperclass() and test until you reach Object.

Making the custom rating bar with layer list and selectors is complex, it is better to override the RatingBar class and create a custom RatingBar. createBackgroundDrawableShape() is the function where you should put your empty state png and createProgressDrawableShape() is the function where you should put your filled state png.

Note: This code will not work with svg for now.

public class CustomRatingBar extends RatingBar {

    @Nullable
    private Bitmap mSampleTile;

    public ShapeDrawableRatingBar(final Context context, final AttributeSet attrs) {
        super(context, attrs);
        setProgressDrawable(createProgressDrawable());
    }

    @Override
    protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        if (mSampleTile != null) {
            final int width = mSampleTile.getWidth() * getNumStars();
            setMeasuredDimension(resolveSizeAndState(width, widthMeasureSpec, 0), getMeasuredHeight());
        }
    }

    protected LayerDrawable createProgressDrawable() {
        final Drawable backgroundDrawable = createBackgroundDrawableShape();
        LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{
            backgroundDrawable,
            backgroundDrawable,
            createProgressDrawableShape()
        });

        layerDrawable.setId(0, android.R.id.background);
        layerDrawable.setId(1, android.R.id.secondaryProgress);
        layerDrawable.setId(2, android.R.id.progress);
        return layerDrawable;
    }

    protected Drawable createBackgroundDrawableShape() {
        final Bitmap tileBitmap = drawableToBitmap(getResources().getDrawable(R.drawable.ic_star_empty));
        if (mSampleTile == null) {
            mSampleTile = tileBitmap;
        }
        final ShapeDrawable shapeDrawable = new ShapeDrawable(getDrawableShape());
        final BitmapShader bitmapShader = new BitmapShader(tileBitmap, Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
        shapeDrawable.getPaint().setShader(bitmapShader);
        return shapeDrawable;
    }

    protected Drawable createProgressDrawableShape() {
        final Bitmap tileBitmap = drawableToBitmap(getResources().getDrawable(R.drawable.ic_star_full));
        final ShapeDrawable shapeDrawable = new ShapeDrawable(getDrawableShape());
        final BitmapShader bitmapShader = new BitmapShader(tileBitmap, Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
        shapeDrawable.getPaint().setShader(bitmapShader);
        return new ClipDrawable(shapeDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
    }

    Shape getDrawableShape() {
        final float[] roundedCorners = new float[]{5, 5, 5, 5, 5, 5, 5, 5};
        return new RoundRectShape(roundedCorners, null, null);
    }

    public static Bitmap drawableToBitmap(Drawable drawable) {
        if (drawable instanceof BitmapDrawable) {
            return ((BitmapDrawable) drawable).getBitmap();
        }

        int width = drawable.getIntrinsicWidth();
        width = width > 0 ? width : 1;
        int height = drawable.getIntrinsicHeight();
        height = height > 0 ? height : 1;

        final Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bitmap);
        drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
        drawable.draw(canvas);

        return bitmap;
    }
}

Getting height transitions to work can be a bit tricky mainly because you have to know the height to animate for. This is further complicated by padding in the element to be animated.

Here is what I came up with:

use a style like this:

    .slideup, .slidedown {
        max-height: 0;            
        overflow-y: hidden;
        -webkit-transition: max-height 0.8s ease-in-out;
        -moz-transition: max-height 0.8s ease-in-out;
        -o-transition: max-height 0.8s ease-in-out;
        transition: max-height 0.8s ease-in-out;
    }
    .slidedown {            
        max-height: 60px ;  // fixed width                  
    }

Wrap your content into another container so that the container you're sliding has no padding/margins/borders:

  <div id="Slider" class="slideup">
    <!-- content has to be wrapped so that the padding and
            margins don't effect the transition's height -->
    <div id="Actual">
            Hello World Text
        </div>
  </div>

Then use some script (or declarative markup in binding frameworks) to trigger the CSS classes.

  $("#Trigger").click(function () {
    $("#Slider").toggleClass("slidedown slideup");
  });

Example here: http://plnkr.co/edit/uhChl94nLhrWCYVhRBUF?p=preview

This works fine for fixed size content. For a more generic soltution you can use code to figure out the size of the element when the transition is activated. The following is a jQuery plug-in that does just that:

$.fn.slideUpTransition = function() {
    return this.each(function() {
        var $el = $(this);
        $el.css("max-height", "0");
        $el.addClass("height-transition-hidden");
    });
};

$.fn.slideDownTransition = function() {
    return this.each(function() {
        var $el = $(this);
        $el.removeClass("height-transition-hidden");

        // temporarily make visible to get the size
        $el.css("max-height", "none");
        var height = $el.outerHeight();

        // reset to 0 then animate with small delay
        $el.css("max-height", "0");

        setTimeout(function() {
            $el.css({
                "max-height": height
            });
        }, 1);
    });
};

which can be triggered like this:

$("#Trigger").click(function () {

    if ($("#SlideWrapper").hasClass("height-transition-hidden"))
        $("#SlideWrapper").slideDownTransition();
    else
        $("#SlideWrapper").slideUpTransition();
});

against markup like this:

<style>
#Actual {
    background: silver;
    color: White;
    padding: 20px;
}

.height-transition {
    -webkit-transition: max-height 0.5s ease-in-out;
    -moz-transition: max-height 0.5s ease-in-out;
    -o-transition: max-height 0.5s ease-in-out;
    transition: max-height 0.5s ease-in-out;
    overflow-y: hidden;            
}
.height-transition-hidden {            
    max-height: 0;            
}
</style>
<div id="SlideWrapper" class="height-transition height-transition-hidden">
    <!-- content has to be wrapped so that the padding and
        margins don't effect the transition's height -->
    <div id="Actual">
     Your actual content to slide down goes here.
    </div>
</div>

I wrote this up recently in a blog post if you're interested in more detail:

http://weblog.west-wind.com/posts/2014/Feb/22/Using-CSS-Transitions-to-SlideUp-and-SlideDown

Try bellow code with jquery :

<html>
<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>

<script>
$(document).ready(function(){
    $('#myForm').on('change', "input#MyFile", function (e) {
        e.preventDefault();
        $("#myForm").submit();
    });
});
</script>
<body>
    <div id="content">
        <form id="myForm" action="action.php" method="POST" enctype="multipart/form-data">
            <input type="file" id="MyFile" value="Upload" />
        </form>
    </div>
</body>
</html>

Just use this website: http://ticons.fokkezb.nl :)

It makes it easier for you, and generates the correct sizes directly

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

I know I am late to answer the function but jquery have a in build function to do this

if(jQuery.type(val) === "undefined"){
    //Some code goes here
}

Refer jquery API document of jquery.type https://api.jquery.com/jQuery.type/ for the same.

I liked qiao's first answer very much! The only thing missing here is to mark the vertexes as visited.

Why we need to do it?
Lets imagine that there is another node number 13 connected from node 11. Now our goal is to find node 13.
After a little bit of a run the queue will look like this:

[[1, 2, 6], [1, 3, 10], [1, 4, 7], [1, 4, 8], [1, 2, 5, 9], [1, 2, 5, 10]]

Note that there are TWO paths with node number 10 at the end.
Which means that the paths from node number 10 will be checked twice. In this case it doesn't look so bad because node number 10 doesn't have any children.. But it could be really bad (even here we will check that node twice for no reason..)
Node number 13 isn't in those paths so the program won't return before reaching to the second path with node number 10 at the end..And we will recheck it..

All we are missing is a set to mark the visited nodes and not to check them again..
This is qiao's code after the modification:

graph = {
    1: [2, 3, 4],
    2: [5, 6],
    3: [10],
    4: [7, 8],
    5: [9, 10],
    7: [11, 12],
    11: [13]
}


def bfs(graph_to_search, start, end):
    queue = [[start]]
    visited = set()

    while queue:
        # Gets the first path in the queue
        path = queue.pop(0)

        # Gets the last node in the path
        vertex = path[-1]

        # Checks if we got to the end
        if vertex == end:
            return path
        # We check if the current node is already in the visited nodes set in order not to recheck it
        elif vertex not in visited:
            # enumerate all adjacent nodes, construct a new path and push it into the queue
            for current_neighbour in graph_to_search.get(vertex, []):
                new_path = list(path)
                new_path.append(current_neighbour)
                queue.append(new_path)

            # Mark the vertex as visited
            visited.add(vertex)


print bfs(graph, 1, 13)

The output of the program will be:

[1, 4, 7, 11, 13]

Without the unneccecery rechecks..

It's simplest to just call the function yourself directly the first time:

foo();
setInterval(foo, delay);

However there are good reasons to avoid setInterval - in particular in some circumstances a whole load of setInterval events can arrive immediately after each other without any delay. Another reason is that if you want to stop the loop you have to explicitly call clearInterval which means you have to remember the handle returned from the original setInterval call.

So an alternative method is to have foo trigger itself for subsequent calls using setTimeout instead:

function foo() {
   // do stuff
   // ...

   // and schedule a repeat
   setTimeout(foo, delay);
}

// start the cycle
foo();

This guarantees that there is at least an interval of delay between calls. It also makes it easier to cancel the loop if required - you just don't call setTimeout when your loop termination condition is reached.

Better yet, you can wrap that all up in an immediately invoked function expression which creates the function, which then calls itself again as above, and automatically starts the loop:

(function foo() {
    ...
    setTimeout(foo, delay);
})();

which defines the function and starts the cycle all in one go.

This just print before exit.

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

void sigint_handler(int);

int  main(void)
{
    signal(SIGINT, sigint_handler);

     while (1){
         pause();   
     }         
    return 0;
}

 void sigint_handler(int sig)
{
    /*do something*/
    printf("killing process %d\n",getpid());
    exit(0);
}

How you detect EOF depends on what you're using to read the stream:

function                  result on EOF or error                    
--------                  ----------------------
fgets()                   NULL
fscanf()                  number of succesful conversions
                            less than expected
fgetc()                   EOF
fread()                   number of elements read
                            less than expected

Check the result of the input call for the appropriate condition above, then call feof() to determine if the result was due to hitting EOF or some other error.

Using fgets():

 char buffer[BUFFER_SIZE];
 while (fgets(buffer, sizeof buffer, stream) != NULL)
 {
   // process buffer
 }
 if (feof(stream))
 {
   // hit end of file
 }
 else
 {
   // some other error interrupted the read
 }

Using fscanf():

char buffer[BUFFER_SIZE];
while (fscanf(stream, "%s", buffer) == 1) // expect 1 successful conversion
{
  // process buffer
}
if (feof(stream)) 
{
  // hit end of file
}
else
{
  // some other error interrupted the read
}

Using fgetc():

int c;
while ((c = fgetc(stream)) != EOF)
{
  // process c
}
if (feof(stream))
{
  // hit end of file
}
else
{
  // some other error interrupted the read
}

Using fread():

char buffer[BUFFER_SIZE];
while (fread(buffer, sizeof buffer, 1, stream) == 1) // expecting 1 
                                                     // element of size
                                                     // BUFFER_SIZE
{
   // process buffer
}
if (feof(stream))
{
  // hit end of file
}
else
{
  // some other error interrupted read
}

Note that the form is the same for all of them: check the result of the read operation; if it failed, then check for EOF. You'll see a lot of examples like:

while(!feof(stream))
{
  fscanf(stream, "%s", buffer);
  ...
}

This form doesn't work the way people think it does, because feof() won't return true until after you've attempted to read past the end of the file. As a result, the loop executes one time too many, which may or may not cause you some grief.

I use application link:AutoHotkey with below code saved in CommentDuplikateSaveClipboard.ahk file. You can edit/remove shortcuts it is easy.
I have link to this file "Shortcut to CommentDuplikateSaveClipboard.ahk" in Autostart in windows.
This script protect your clipboard.
If you are more curious you would add shortcuts to thisable/enable script.
I sometimes use very impressive Multi Clipboard script to easy handle with many clips saved on disk and use with CTRL+C,X,V to copy,paste,cut,next,previous,delete this,delete all.

;CommentDuplikateSaveClipboard.ahk

!c:: ; Alt+C === Duplicate Line
^d:: ; Ctrl+D
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{END}{ENTER}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!x:: ; Alt+X === Comment Duplicate Line
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{LEFT}//{END}{ENTER}{CTRLDOWN}v{CTRLUP}{HOME}

Since the Support Library v24.2.0. you can achivie this very easy

What you need to do is just:

1. Add the design library to your dependecies

   dependencies {
        compile "com.android.support:design:25.1.0"
   }
   

2. Use TextInputEditText in conjunction with TextInputLayout

   <android.support.design.widget.TextInputLayout
       android:id="@+id/etPasswordLayout"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:passwordToggleEnabled="true">
   
       <android.support.design.widget.TextInputEditText
           android:id="@+id/etPassword"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:hint="@string/password_hint"
           android:inputType="textPassword"/>
   </android.support.design.widget.TextInputLayout>
   

passwordToggleEnabled attribute will make the password toggle appear

3. In your root layout don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto"

4. You can customize your password toggle by using:

app:passwordToggleDrawable - Drawable to use as the password input visibility toggle icon.
app:passwordToggleTint - Icon to use for the password input visibility toggle.
app:passwordToggleTintMode - Blending mode used to apply the background tint.

More details in TextInputLayout documentation.

I hope what you are trying to achieve is like this. For this please use Box layout.

package com.kcing.kailas.sample.client;

import javax.swing.BoxLayout;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
import javax.swing.WindowConstants;

public class Testing extends JFrame {

    private JPanel jContentPane = null;

    public Testing() {
        super();
        initialize();
    }

    private void initialize() {
        this.setSize(300, 200);
        this.setContentPane(getJContentPane());
        this.setTitle("JFrame");
    }

    private JPanel getJContentPane() {
        if (jContentPane == null) {
            jContentPane = new JPanel();
            jContentPane.setLayout(null);

            JPanel panel = new JPanel();

            panel.setBounds(61, 11, 81, 140);
            panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
            jContentPane.add(panel);

            JCheckBox c1 = new JCheckBox("Check1");
            panel.add(c1);
            c1 = new JCheckBox("Check2");
            panel.add(c1);
            c1 = new JCheckBox("Check3");
            panel.add(c1);
            c1 = new JCheckBox("Check4");
            panel.add(c1);
        }
        return jContentPane;
    }

    public static void main(String[] args) throws Exception {
        Testing frame = new Testing();
        frame.setVisible(true);
        frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
    }
}

The best practice would be to create a module separately which has only one method whose task we be to give a logger handler to the the calling method. Save this file as m_logger.py

import logger, logging

def getlogger():
    # logger
    logger = logging.getLogger(__name__)
    logger.setLevel(logging.DEBUG)
    # create console handler and set level to debug
    #ch = logging.StreamHandler()
    ch = logging.FileHandler(r'log.txt')
    ch.setLevel(logging.DEBUG)
    # create formatter
    formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
    # add formatter to ch
    ch.setFormatter(formatter)
    # add ch to logger
    logger.addHandler(ch)
    return logger

Now call the getlogger() method whenever logger handler is needed.

from m_logger import getlogger
logger = getlogger()
logger.info('My mssg')

If you want to keep using the Array.prototype.include() in javascript you can use this script: github-script-ie-include That converts automatically the include() to the match() function if it detects IE.

Other option is using always thestring.match(Regex(expression))

import { Component, Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'timePipe'
})
export class TimeValuePipe implements PipeTransform {

  transform(value: any, args?: any): any {
   var hoursMinutes = value.split(/[.:]/);
  var hours = parseInt(hoursMinutes[0], 10);
  var minutes = hoursMinutes[1] ? parseInt(hoursMinutes[1], 10) : 0;
  console.log('hours ', hours);
  console.log('minutes ', minutes/60);
  return (hours + minutes / 60).toFixed(2);
  }
}
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  name = 'Angular';
  order = [
    {
      "order_status": "Still at Shop",
      "order_id": "0:02"
    },
    {
      "order_status": "On the way",
      "order_id": "02:29"
    },
    {
      "order_status": "Delivered",
      "order_id": "16:14"
    },
     {
      "order_status": "Delivered",
      "order_id": "07:30"
    }
  ]
}

Invoke this module in App.Module.ts file.

You could use x ** (1. / 3) to compute the (floating-point) cube root of x.

The slight subtlety here is that this works differently for negative numbers in Python 2 and 3. The following code, however, handles that:

def is_perfect_cube(x):
    x = abs(x)
    return int(round(x ** (1. / 3))) ** 3 == x

print(is_perfect_cube(63))
print(is_perfect_cube(64))
print(is_perfect_cube(65))
print(is_perfect_cube(-63))
print(is_perfect_cube(-64))
print(is_perfect_cube(-65))
print(is_perfect_cube(2146689000)) # no other currently posted solution
                                   # handles this correctly

This takes the cube root of x, rounds it to the nearest integer, raises to the third power, and finally checks whether the result equals x.

The reason to take the absolute value is to make the code work correctly for negative numbers across Python versions (Python 2 and 3 treat raising negative numbers to fractional powers differently).

Reading the docs I find the section Passing Variables On The Command Line, that gives this example:

ansible-playbook release.yml --extra-vars "version=1.23.45 other_variable=foo"

Others examples demonstrate how to load from JSON string (=1.2) or file (=1.3)

What exactly do you want to know?

The shared library soname? That's part of the filename, libstdc++.so.6, or shown by readelf -d /usr/lib64/libstdc++.so.6 | grep soname.

The minor revision number? You should be able to get that by simply checking what the symlink points to:

$ ls -l  /usr/lib/libstdc++.so.6
lrwxrwxrwx. 1 root root 19 Mar 23 09:43 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.16

That tells you it's 6.0.16, which is the 16th revision of the libstdc++.so.6 version, which corresponds to the GLIBCXX_3.4.16 symbol versions.

Or do you mean the release it comes from? It's part of GCC so it's the same version as GCC, so unless you've screwed up your system by installing unmatched versions of g++ and libstdc++.so you can get that from:

$ g++ -dumpversion
4.6.3

Or, on most distros, you can just ask the package manager. On my Fedora host that's

$ rpm -q libstdc++
libstdc++-4.6.3-2.fc16.x86_64
libstdc++-4.6.3-2.fc16.i686

As other answers have said, you can map releases to library versions by checking the ABI docs

Simply use

1. shift + cmd + P
2. Search Select Interpreter

3. Select it and it will show you the list of your virtual environment created via conda and other python versions

4. select the environment and you are ready to go.

Quoting the 'Select and activate an environment' docs

Selecting an interpreter from the list adds an entry for python.pythonPath with
the path to the interpreter inside your Workspace Settings.

Alternate solution

Create a column that will store the month:

data['month'] = data['date'].dt.month

Create a column that will store the year:

data['year'] = data['date'].dt.year

Use the input() built-in function to get a input line from the user.

You can read the help here.

You can use the following code to get several line at once (finishing by an empty one):

while input() != '':
    do_thing

If you don't care about IE =6, you could use pure CSS ...

.forum:hover { background-color: #380606; }

.forum { color: white; }_x000D_
.forum:hover { background-color: #380606 !important; }_x000D_
/* we use !important here to override specificity. see http://stackoverflow.com/q/5805040/ */_x000D_
_x000D_

<meta charset=utf-8>_x000D_

<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

With jQuery, usually it is better to create a specific class for this style:

.forum_hover { background-color: #380606; }

and then apply the class on mouseover, and remove it on mouseout.

$('.forum').hover(function(){$(this).toggleClass('forum_hover');});

$(document).ready(function(){_x000D_
  $('.forum').hover(function(){$(this).toggleClass('forum_hover');});_x000D_
});

.forum_hover { background-color: #380606 !important; }_x000D_
_x000D_

<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

If you must not modify the class, you could save the original background color in .data():

  $('.forum').data('bgcolor', '#380606').hover(function(){
    var $this = $(this);
    var newBgc = $this.data('bgcolor');
    $this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);
  });

$(document).ready(function(){_x000D_

The ENABLEDELAYEDEXPANSION part is REQUIRED in certain programs that use delayed expansion, that is, that takes the value of variables that were modified inside IF or FOR commands by enclosing their names in exclamation-marks.

If you enable this expansion in a script that does not require it, the script behaves different only if it contains names enclosed in exclamation-marks !LIKE! !THESE!. Usually the name is just erased, but if a variable with the same name exist by chance, then the result is unpredictable and depends on the value of such variable and the place where it appears.

The SETLOCAL part is REQUIRED in just a few specialized (recursive) programs, but is commonly used when you want to be sure to not modify any existent variable with the same name by chance or if you want to automatically delete all the variables used in your program. However, because there is not a separate command to enable the delayed expansion, programs that require this must also include the SETLOCAL part.

I know this is an old post but just for reference. Here is how to append without the special case check for an empty list, although at the expense of more complex looking code.

void Append(List * l, Node * n)
{
    Node ** next = &list->Head;
    while (*next != NULL) next = &(*next)->Next;
    *next = n;
    n->Next = NULL;
}

def find_substring():
    s = 'bobobnnnnbobmmmbosssbob'
    cnt = 0
    for i in range(len(s)):
        if s[i:i+3] == 'bob':
            cnt += 1
    print 'bob found: ' + str(cnt)
    return cnt

def main():
    print(find_substring())

You'll be starting a PHP process, opening a DB connection, having the DB read image data from the same disk and RAM for cache as filesystem would, transferring it over few sockets and buffers and then pushing out via PHP, which by default makes it non-cacheable and adds overhead of chunked HTTP encoding.

OTOH modern web servers can serve images with just few optimized kernel calls (memory-mapped file and that memory area passed to TCP stack), so that they don't even copy memory around and there's almost no overhead.

That's a difference between being able to serve 20 or 2000 images in parallel on one machine.

So don't do it unless you absolutely need transactional integrity (and actually even that can be done with just image metadata in DB and filesystem cleanup routines) and know how to improve PHP's handling of HTTP to be suitable for images.

I had the same error after moving to a new laptop (Windows 10). In addition to setting Copy Local to true as mentioned above, I had to install the Crystal Reports 32-bit runtime engine for .Net Framework, even though everything else is set to run in a 64-bit environment. Hope that helps.

Just with bash:

convert_date () {
    local months=( JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC )
    local i
    for (( i=0; i<11; i++ )); do
        [[ $2 = ${months[$i]} ]] && break
    done
    printf "%4d%02d%02d\n" $3 $(( i+1 )) $1
}

And invoke it like this

d=$( convert_date 27 JUN 2011 )

Or if the "old" date string is stored in a variable

d_old="27 JUN 2011"
d=$( convert_date $d_old )  # not quoted

This script worked for me:

DELETE t
FROM table t
INNER JOIN join_table jt ON t.fk_column = jt.id
WHERE jt.comdition_column…;

I came up with a solution similar to Christians but without depending on the Community MSBuild tasks, this is not an option for me as I do not want to install these tasks for all of our developers.

I am generating code and compiling to an Assembly and want to auto-increment version numbers. However, I can not use the VS 6.0.* AssemblyVersion trick as it auto-increments build numbers each day and breaks compatibility with Assemblies that use an older build number. Instead, I want to have a hard-coded AssemblyVersion but an auto-incrementing AssemblyFileVersion. I've accomplished this by specifying AssemblyVersion in the AssemblyInfo.cs and generating a VersionInfo.cs in MSBuild like this,

  <PropertyGroup>
    <Year>$([System.DateTime]::Now.ToString("yy"))</Year>
    <Month>$([System.DateTime]::Now.ToString("MM"))</Month>
    <Date>$([System.DateTime]::Now.ToString("dd"))</Date>
    <Time>$([System.DateTime]::Now.ToString("HHmm"))</Time>
    <AssemblyFileVersionAttribute>[assembly:System.Reflection.AssemblyFileVersion("$(Year).$(Month).$(Date).$(Time)")]</AssemblyFileVersionAttribute>
  </PropertyGroup>
  <Target Name="BeforeBuild">
    <WriteLinesToFile File="Properties\VersionInfo.cs" Lines="$(AssemblyFileVersionAttribute)" Overwrite="true">
    </WriteLinesToFile>
  </Target>

This will generate a VersionInfo.cs file with an Assembly attribute for AssemblyFileVersion where the version follows the schema of YY.MM.DD.TTTT with the build date. You must include this file in your project and build with it.

I got an example here that struck me!

foo.py

import bar

class gX(object):
    g = 10

bar.py

from foo import gX

o = gX()

main.py

import foo
import bar

print "all done"

At the command line: $ python main.py

Traceback (most recent call last):
  File "m.py", line 1, in <module>
    import foo
  File "/home/xolve/foo.py", line 1, in <module>
    import bar
  File "/home/xolve/bar.py", line 1, in <module>
    from foo import gX
ImportError: cannot import name gX

Use -->

comboBox1.DataSource = colors.ToList();

Unless the dictionary is converted to list, combo-box can't recognize its members.

>>> s = '/tmp/10508.constantstring'
>>> s.split('/tmp/')[1].split('constantstring')[0].strip('.')

I think the reason that this is happening could be because TextBox1 is scoping to the VBA module and its associated sheet, while Range is scoping to the "Active Sheet".

EDIT

It looks like you may be able to use the GetObject function to pull the textbox from the workbook.

It depends on the compiler. If you compile with, say, G++ on Linux and VC++ on Windows, this will do :

#ifdef linux
    ...
#elif _WIN32
    ...
#else
    ...
#endif

You are not writing your code inside any function, you can return from functions only. Remove return statement and just print the value you want.

This is implementation dependent, as the C standard does NOT define the signed-ness of char. Depending on the platform, char may be signed or unsigned, so you need to explicitly ask for signed char or unsigned char if your implementation depends on it. Just use char if you intend to represent characters from strings, as this will match what your platform puts in the string.

The difference between signed char and unsigned char is as you'd expect. On most platforms, signed char will be an 8-bit two's complement number ranging from -128 to 127, and unsigned char will be an 8-bit unsigned integer (0 to 255). Note the standard does NOT require that char types have 8 bits, only that sizeof(char) return 1. You can get at the number of bits in a char with CHAR_BIT in limits.h. There are few if any platforms today where this will be something other than 8, though.

There is a nice summary of this issue here.

As others have mentioned since I posted this, you're better off using int8_t and uint8_t if you really want to represent small integers.

def binary(decimal) :
    otherBase = ""
    while decimal != 0 :
        otherBase  =  str(decimal % 2) + otherBase
        decimal    //=  2
    return otherBase

print binary(10)

output:

1010

If you want to do the same thing in C# based on Ciarán Answer

string sSheetName = null;
string sConnection = null;
DataTable dtTablesList = default(DataTable);
OleDbCommand oleExcelCommand = default(OleDbCommand);
OleDbDataReader oleExcelReader = default(OleDbDataReader);
OleDbConnection oleExcelConnection = default(OleDbConnection);

sConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Test.xls;Extended Properties=\"Excel 12.0;HDR=No;IMEX=1\"";

oleExcelConnection = new OleDbConnection(sConnection);
oleExcelConnection.Open();

dtTablesList = oleExcelConnection.GetSchema("Tables");

if (dtTablesList.Rows.Count > 0) 
{
    sSheetName = dtTablesList.Rows[0]["TABLE_NAME"].ToString();
}

dtTablesList.Clear();
dtTablesList.Dispose();


if (!string.IsNullOrEmpty(sSheetName)) {
    oleExcelCommand = oleExcelConnection.CreateCommand();
    oleExcelCommand.CommandText = "Select * From [" + sSheetName + "]";
    oleExcelCommand.CommandType = CommandType.Text;
    oleExcelReader = oleExcelCommand.ExecuteReader();
    nOutputRow = 0;

    while (oleExcelReader.Read())
    {
    }
    oleExcelReader.Close();
}
oleExcelConnection.Close();

here is another way read Excel into a DataTable without using OLEDB very quick Keep in mind that the file ext would have to be .CSV for this to work properly

private static DataTable GetDataTabletFromCSVFile(string csv_file_path)
{
    csvData = new DataTable(defaultTableName);
    try
    {
        using (TextFieldParser csvReader = new TextFieldParser(csv_file_path))
        {
            csvReader.SetDelimiters(new string[]
            {
                tableDelim 
            });
            csvReader.HasFieldsEnclosedInQuotes = true;
            string[] colFields = csvReader.ReadFields();
            foreach (string column in colFields)
            {
                DataColumn datecolumn = new DataColumn(column);
                datecolumn.AllowDBNull = true;
                csvData.Columns.Add(datecolumn);
            }

            while (!csvReader.EndOfData)
            {
                string[] fieldData = csvReader.ReadFields();
                //Making empty value as null
                for (int i = 0; i < fieldData.Length; i++)
                {
                    if (fieldData[i] == string.Empty)
                    {
                        fieldData[i] = string.Empty; //fieldData[i] = null
                    }
                    //Skip rows that have any csv header information or blank rows in them
                    if (fieldData[0].Contains("Disclaimer") || string.IsNullOrEmpty(fieldData[0]))
                    {
                        continue;
                    }
                }
                csvData.Rows.Add(fieldData);
            }
        }
    }
    catch (Exception ex)
    {
    }
    return csvData;
}

If you do a simple test:

import time
import sys

def run1(runs):
    x = 0
    cur = time.time()
    while x < runs:
        x += 1
        print >> sys.stderr, 'X'
    elapsed = (time.time()-cur)
    return elapsed

def run2(runs):
    x = 0
    cur = time.time()
    while x < runs:
        x += 1
        sys.stderr.write('X\n')
        sys.stderr.flush()
    elapsed = (time.time()-cur)
    return elapsed

def compare(runs):
    sum1, sum2 = 0, 0
    x = 0
    while x < runs:
        x += 1
        sum1 += run1(runs)
        sum2 += run2(runs)
    return sum1, sum2

if __name__ == '__main__':
    s1, s2 = compare(1000)
    print "Using (print >> sys.stderr, 'X'): %s" %(s1)
    print "Using (sys.stderr.write('X'),sys.stderr.flush()):%s" %(s2)
    print "Ratio: %f" %(float(s1) / float(s2))

You will find that sys.stderr.write() is consistently 1.81 times faster!

I tried below code to find duplicate values from list

1) create a set of duplicate list

2) Iterated through set by looking in duplicate list.

glist=[1, 2, 3, "one", 5, 6, 1, "one"]
x=set(glist)
dup=[]
for c in x:
    if(glist.count(c)>1):
        dup.append(c)
print(dup)

OUTPUT

[1, 'one']

Now get the all index for duplicate element

glist=[1, 2, 3, "one", 5, 6, 1, "one"]
x=set(glist)
dup=[]
for c in x:
    if(glist.count(c)>1):
        indices = [i for i, x in enumerate(glist) if x == c]
        dup.append((c,indices))
print(dup)

OUTPUT

[(1, [0, 6]), ('one', [3, 7])]

Hope this helps someone

You could pass an object as attribute and read it into the directive like this:

<div my-directive="{id:123,name:'teo',salary:1000,color:red}"></div>

app.directive('myDirective', function () {
    return {            
        link: function (scope, element, attrs) {
           //convert the attributes to object and get its properties
           var attributes = scope.$eval(attrs.myDirective);       
           console.log('id:'+attributes.id);
           console.log('id:'+attributes.name);
        }
    };
});

If you want to open it for a range and for a protocol

ufw allow 11200:11299/tcp
ufw allow 11200:11299/udp

1. Go to Control Panel
2. Double click on Java
3. Open the Security tab
4. Select Medium
5. Click on Apply
6. Restart your web browser

That's it!

It is possible using ConfigTransform build target available as a Nuget package - https://www.nuget.org/packages/CodeAssassin.ConfigTransform/

All "web.*.config" transform files will be transformed and output as a series of "web.*.config.transformed" files in the build output directory regardless of the chosen build configuration.

The same applies to "app.*.config" transform files in non-web projects.

and then adding the following target to your *.csproj.

<Target Name="TransformActiveConfiguration" Condition="Exists('$(ProjectDir)/Web.$(Configuration).config')" BeforeTargets="Compile" >
    <TransformXml Source="$(ProjectDir)/Web.Config" Transform="$(ProjectDir)/Web.$(Configuration).config" Destination="$(TargetDir)/Web.config" />
</Target>

Posting an answer as this is the first Stackoverflow post that appears in Google on the subject.

Yes you can target those specificaly using input[type=submit] e.g.

.myFormClass input[type=submit] {
  margin: 10px;
  color: white;
  background-color: blue;
}

in .net core if you want to access querystring in our view use it like

@Context.Request.Query["yourKey"]

if we are in location where @Context is not avilable we can inject it like

@inject Microsoft.AspNetCore.Http.IHttpContextAccessor HttpContextAccessor
@if (HttpContextAccessor.HttpContext.Request.Query.Keys.Contains("yourKey"))
{
      <text>do something </text>
}

also for cookies

HttpContextAccessor.HttpContext.Request.Cookies["DeniedActions"]

Your FMAT.h requires a definition of std::string in order to complete the definition of class FMAT. In FMAT.cpp, you've done this by #include <string> before #include "FMAT.h". You haven't done that in your main file.

Your attempt to forward declare string was incorrect on two levels. First you need a fully qualified name, std::string. Second this works only for pointers and references, not for variables of the declared type; a forward declaration doesn't give the compiler enough information about what to embed in the class you're defining.

Arrays.asList(arr).iterator();

Or write your own, implementing ListIterator interface..

Be sure you are setting PATH to Program Files (x86) not Program Files. That solved my problem.

In this case, no need for a directive. This does the job :

<button ng-click="count = count + 1" ng-init="count=0">
  Increment
</button>
<span>
  count: {{count}}
</span>

Source: https://docs.angularjs.org/api/ng/directive/ngClick

If you want cmd.exe to not close, and able to continue to type, use cmd /k

Just felt the need to clarify what /k does (from windows website):

/k : Carries out the command specified by string and continues.

So cmd /k without follow up command at the end of bat file will just keep cmd.exe window open for further use.

On the other hand pause at the end of a batch file will simply pause the process and terminate cmd.exe on first button press

There are two methods by which you can round up your double value.

1. Math.ceil
2. Math.floor

If you want your answer 4.90625 as 4 then you should use Math.floor and if you want your answer 4.90625 as 5 then you can use Math.ceil

You can refer following code for that.

public class TestClass {

    public static void main(String[] args) {
        int floorValue = (int) Math.floor((double)157 / 32);
        int ceilValue = (int) Math.ceil((double)157 / 32);
        System.out.println("Floor: "+floorValue);
        System.out.println("Ceil: "+ceilValue);

    }

}

This scenario comes up when you -- or forces greater than you -- have mangled a file in your local repo and you just want to restore a fresh copy of the latest version of it from the repo. Simply deleting the file with /bin/rm (not git rm) or renaming/hiding it and then issuing a git pull will not work: git notices the file's absence and assumes you probably want it gone from the repo (git diff will show all lines deleted from the missing file).

git pull not restoring locally missing files has always frustrated me about git, perhaps since I have been influenced by other version control systems (e.g. svn update which I believe will restore files that have been locally hidden).

git reset --hard HEAD is an alternative way to restore the file of interest as it throws away any uncommitted changes you have. However, as noted here, git reset is is a potentially dangerous command if you have any other uncommitted changes that you care about.

The git fetch ... git checkout strategy noted above by @chrismillah is a nice surgical way to restore the file in question.

The easiest way is:

RandomAccessFile in = new RandomAccessFile("filename", "r"); 
int i = in.readInt();

-- or --

DataInputStream in = new DataInputStream(new BufferedInputStream(
    new FileInputStream("filename"))); 
int i = in.readInt();

You're looking for the onclose event.

note that not all browsers support this (for example firefox 2)

when in pyspark multiple conditions can be built using &(for and) and | (for or).

Note:In pyspark t is important to enclose every expressions within parenthesis () that combine to form the condition

%pyspark
dataDF = spark.createDataFrame([(66, "a", "4"), 
                                (67, "a", "0"), 
                                (70, "b", "4"), 
                                (71, "d", "4")],
                                ("id", "code", "amt"))
dataDF.withColumn("new_column",
       when((col("code") == "a") | (col("code") == "d"), "A")
      .when((col("code") == "b") & (col("amt") == "4"), "B")
      .otherwise("A1")).show()

In Spark Scala code (&&) or (||) conditions can be used within when function

//scala
val dataDF = Seq(
      (66, "a", "4"), (67, "a", "0"), (70, "b", "4"), (71, "d", "4"
      )).toDF("id", "code", "amt")
dataDF.withColumn("new_column",
       when(col("code") === "a" || col("code") === "d", "A")
      .when(col("code") === "b" && col("amt") === "4", "B")
      .otherwise("A1")).show()

=======================

Output:
+---+----+---+----------+
| id|code|amt|new_column|
+---+----+---+----------+
| 66|   a|  4|         A|
| 67|   a|  0|         A|

There is also a Windows built-in program called findstr.exe with which you can search within files.

>findstr /s "provider=sqloledb" *.cs

As everyone has mentioned. It's different line ending style. MacOSX uses Unix line endings - i.e. LF (line feed).

Windows uses both CR (carriage return) & LF (line feed) as a line ending. Since you're using both windows and mac thats where the problem stems from.

If you create a file in windows and then bring it onto the mac you might see these ^M characters at the end of the lines.

If you want to remove them you can do this very easily in emacs. Just highlight and copy the ^M character and do a query-replace ^M with and you'e done.

EDIT: Some other links that may be of help. http://xahlee.org/emacs/emacs_adv_tips.html

This one helps you configure emacs to use a particular type of line-ending style. http://www.emacswiki.org/emacs/EndOfLineTips

The best way to handle styling is by using classes with set of css properties.

example:

<Component className={this.getColor()} />

getColor() {
    let class = "badge m2";
    class += this.state.count===0 ? "warning" : danger;
    return class;
}

In case anyone finds it useful, www.querymongo.com does translation between SQL and MongoDB, including OR clauses. It can be really helpful for figuring out syntax when you know the SQL equivalent.

In the case of OR statements, it looks like this

SQL:

SELECT * FROM collection WHERE columnA = 3 OR columnB = 'string';

MongoDB:

db.collection.find({
    "$or": [{
        "columnA": 3
    }, {
        "columnB": "string"
    }]
});
