using (var client = new HttpClient(handler))
            {
                ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
                var response = await client.SendAsync(new HttpRequestMessage(HttpMethod.Get, apiEndPoint)).ConfigureAwait(false);
                await response.Content.ReadAsStringAsync().ConfigureAwait(false);
            }

This worked for me

Just in case you don't want to use stored proc, here's a simple query version

select * 
  from information_schema.columns 
 where table_name = 'aspnet_Membership'
 order by ordinal_position

@Ashika's answer works fantastically if you want (0,0) to be represented in the top, left corner, per normal CS convention. If however you would prefer to use normal mathematical convention and put (0,0) in the lower left hand corner, you could use this:

LinkedList<String> printList = new LinkedList<String>();
for (char[] row: array) {
    printList.addFirst(Arrays.toString(row));;
}
while (!printList.isEmpty())
    System.out.println(printList.removeFirst());

This used LIFO (Last In First Out) to reverse the order at print time.

Vulgo has the right idea on this thread. I believe his solution is the easiest of the bunch, although his answer could have been a little more in-depth. Here is something that worked for me. I have provided an example.

<h1 id="hello1">Hello World</h1>
<h2 id="hello2">Random</h2>
<button id="click">Click To Hide</button>

<script>

  document.getElementById('click').addEventListener('click', function(){
    doStuff();
  });

  function doStuff() {
    for(var i=1; i<=2; i++){
        var el = document.getElementById("hello" + i);
        el.style.display = 'none';
    }
  }

</script>

Obviously just change the integers in the for loop to account for however many elements you are targeting, which in this example was 2.

First, I can give you the answer for one table:

The trouble with all these INTO OUTFILE or --tab=tmpfile (and -T/path/to/directory) answers is that it requires running mysqldump on the same server as the MySQL server, and having those access rights.

My solution was simply to use mysql (not mysqldump) with the -B parameter, inline the SELECT statement with -e, then massage the ASCII output with sed, and wind up with CSV including a header field row:

Example:

 mysql -B -u username -p password database -h dbhost -e "SELECT * FROM accounts;" \
 | sed "s/\"/\"\"/g;s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g"

"id","login","password","folder","email" "8","mariana","xxxxxxxxxx","mariana","" "3","squaredesign","xxxxxxxxxxxxxxxxx","squaredesign","[email protected]" "4","miedziak","xxxxxxxxxx","miedziak","[email protected]" "5","Sarko","xxxxxxxxx","Sarko","" "6","Logitrans Poland","xxxxxxxxxxxxxx","LogitransPoland","" "7","Amos","xxxxxxxxxxxxxxxxxxxx","Amos","" "9","Annabelle","xxxxxxxxxxxxxxxx","Annabelle","" "11","Brandfathers and Sons","xxxxxxxxxxxxxxxxx","BrandfathersAndSons","" "12","Imagine Group","xxxxxxxxxxxxxxxx","ImagineGroup","" "13","EduSquare.pl","xxxxxxxxxxxxxxxxx","EduSquare.pl","" "101","tmp","xxxxxxxxxxxxxxxxxxxxx","_","[email protected]"

Add a > outfile.csv at the end of that one-liner, to get your CSV file for that table.

Next, get a list of all your tables with

mysql -u username -ppassword dbname -sN -e "SHOW TABLES;"

From there, it's only one more step to make a loop, for example, in the Bash shell to iterate over those tables:

 for tb in $(mysql -u username -ppassword dbname -sN -e "SHOW TABLES;"); do
     echo .....;
 done

Between the do and ; done insert the long command I wrote in Part 1 above, but substitute your tablename with $tb instead.

template <class T>
void transpose( const std::vector< std::vector<T> > & a,
std::vector< std::vector<T> > & b,
int width, int height)
{
    for (int i = 0; i < width; i++)
    {
        for (int j = 0; j < height; j++)
        {
            b[j][i] = a[i][j];
        }
    }
} 

For the easiest scenario when you hide cells at the very bottom of table view, you could adjust tableView's contentInset after you hide cell:

- (void)adjustBottomInsetForHiddenSections:(NSInteger)numberOfHiddenSections
{
    CGFloat bottomInset = numberOfHiddenSections * 44.0; // or any other 'magic number
    self.tableView.contentInset = UIEdgeInsetsMake(self.tableView.contentInset.top, self.tableView.contentInset.left, -bottomInset, self.tableView.contentInset.right);
}

Try Freshen command:

rpm -Fvh *.rpm

You can't modify the collection, not even the values. You could save these cases and remove them later. It would end up like this:

Dictionary<string, int> colStates = new Dictionary<string, int>();
// ...
// Some code to populate colStates dictionary
// ...

int OtherCount = 0;
List<string> notRelevantKeys = new List<string>();

foreach (string key in colStates.Keys)
{

    double Percent = colStates[key] / colStates.Count;

    if (Percent < 0.05)
    {
        OtherCount += colStates[key];
        notRelevantKeys.Add(key);
    }
}

foreach (string key in notRelevantKeys)
{
    colStates[key] = 0;
}

colStates.Add("Other", OtherCount);

This solution for Ubuntu Host, Macos Guest

1. disable SIP
2. install mac ports
3. sudo launchctl unload /Library/Apple/System/Library/LaunchDaemons/com.apple.usbmuxd.plist
4. sudo port install usbmuxd
5. sudo usbmuxd --foreground
6. then connect iPhone and let the guest to take control

Disabling SIP

1. Start vmware
2. select guest and "power to firmware"
3. in efi menu, enter setup > config boot options > add boot options > select recovery partition > select boot.efi
4. at input file description hit and type in label e.g. "recovery" > commit changes and exit
5. boot from recovery and be patient
6. follow prompt until you see OS X Utilities menu
7. At the very top menu select Utilities > Terminal
8. In terminal enter "csrutil status"
9. then csrutil disable
10. then csrutil status
11. then reboot > hit enter once or twice
12. Double check in OSX Terminal app to ensure SIP is disabled

Finally, disable HiDPI:

$ sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool NO

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

when it comes to subquery and co-related query both have inner query and outer query the only difference is in subquery the inner query doesn't depend on outer query, whereas in co-related inner query depends on outer.

You can use isinstance if you have an instance, or issubclass if you have a class. Normally thought its a bad idea. Normally in Python you work out if an object is capable of something by attempting to do that thing to it.

Here is a one-liner for Mac/Linux to connect to an Android device over Wi-Fi, but first you must connect to the device via USB.

# sleep 5 is to wait for the device to restart listening.

In android gradle 0.4.0 you can just do:

println System.env.HOME

classpath com.android.tools.build:gradle-experimental:0.4.0

If you'll go through these steps:

1. In the Terminal type brew install jmeter and hit Enter
2. When it'll be done type jmeter and hit Enter again

The solution below does only one groupBy and extract the rows of your dataframe that contain the maxValue in one shot. No need for further Joins, or Windows.

import org.apache.spark.sql.Row
import org.apache.spark.sql.catalyst.encoders.RowEncoder
import org.apache.spark.sql.DataFrame

//df is the dataframe with Day, Category, TotalValue

implicit val dfEnc = RowEncoder(df.schema)

val res: DataFrame = df.groupByKey{(r) => r.getInt(0)}.mapGroups[Row]{(day: Int, rows: Iterator[Row]) => i.maxBy{(r) => r.getDouble(2)}}

how about this solution?

if type(x) in (float, int):
    # do whatever
else:
    # do whatever

Another base R option could be gl():

gl(5, 3)

Where the output is a factor:

 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
Levels: 1 2 3 4 5

If integers are needed, you can convert it:

as.numeric(gl(5, 3))

 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5

class First(object):
  def __init__(self, a):
    print "first", a
    super(First, self).__init__(20)

class Second(object):
  def __init__(self, a):
    print "second", a
    super(Second, self).__init__()

class Third(First, Second):
  def __init__(self):
    super(Third, self).__init__(10)
    print "that's it"

t = Third()

Output is

first 10
second 20
that's it

Call to Third() locates the init defined in Third. And call to super in that routine invokes init defined in First. MRO=[First, Second]. Now call to super in init defined in First will continue searching MRO and find init defined in Second, and any call to super will hit the default object init. I hope this example clarifies the concept.

If you don't call super from First. The chain stops and you will get the following output.

first 10
that's it

The "Issue 2" answer given by @Sagar works for the majority of git servers such as gitorious.

However, there will be a name clash in a system like gitolite where the public ssh keys are checked in as files named with the username, ie keydir/jenkins.pub. What if there are multiple jenkins servers that need to access the same gitolite server?

(Note: this is about running the Jenkins daemon not running a build job as a user (addressed by @Sagar's "Issue 1").)

So in this case you do need to run the Jenkins daemon as a different user.

There are two steps:

Step 1

The main thing is to update the JENKINS_USER environment variable. Here's a patch showing how to change the user to ptran.

My Code to insert data is not working. It showing no error but data is not showing in my database.

}

some applications will treat "localhost" specially. the mysql client will treat localhost as a request to connect to the local unix domain socket instead of using tcp to connect to the server on 127.0.0.1. This may be faster, and may be in a different authentication zone.

I don't know of other apps that treat localhost differently than 127.0.0.1, but there probably are some.

You must attach the event after insert elements, like that you don't attach a global event on your document but a specific event on the inserted elements.

e.g.

document.getElementById('form').addEventListener('submit', function(e) {_x000D_

  var name = document.getElementById('txtName').value;_x000D_
  var idElement = 'btnPrepend';_x000D_
  var html = `_x000D_
    <ul>_x000D_
      <li>${name}</li>_x000D_
    </ul>_x000D_
    <input type="button" value="prepend" id="${idElement}" />_x000D_
  `;_x000D_
  /* Insert the html into your DOM */_x000D_
  insertHTML('form', html);_x000D_
  /* Add an event listener after insert html */_x000D_
  addEvent(idElement);_x000D_
});_x000D_
_x000D_
const insertHTML = (tag = 'form', html, position = 'afterend', index = 0) => {_x000D_
  document.getElementsByTagName(tag)[index].insertAdjacentHTML(position, html);_x000D_
}_x000D_
const addEvent = (id, event = 'click') => {_x000D_
  document.getElementById(id).addEventListener(event, function() {_x000D_
    insertHTML('ul', '<li>Prepending data</li>', 'afterbegin')_x000D_
  });_x000D_
}

<form id="form">_x000D_

dist.plot_summary()

# Make prediction on new datapoints based on the fit
dist.predict(y)

# Retrieve your pvalues with 
dist.y_pred
# array(['down', 'none', 'none', 'up', 'up'], dtype='<U4')
dist.y_proba
array([0.02040816, 0.02040816, 0.02040816, 0.        , 0.        ])

# Or in one dataframe
dist.df

# The plot function will now also include the predictions of y
dist.plot()

Note that in this case, all points will be significant because of the uniform distribution. You can filter with the dist.y_pred if required.

I got this error when there were files in the Dockerfile directory that were not accessible by the current user. docker could thus not upload the full context to the daemon and brought the "Couldn't connect to Docker daemon at http+docker://localunixsocket" message.

You can simply compare it with System.DBNull.Value

You could always listen to the window resize event. If, on that event, the window went from being taller than it is wide to wider than it is tall (or vice versa), you can be pretty sure the phone orientation was just changed.

The exact way to check is:

//takes care of boolen, undefined and empty

isNaN(x) || typeof(x) ==='boolean' || typeof(x) !=='undefined' || x!=='' ? 'is really a nan' : 'is a number'

f = open(filename,'r')
f.seek(-1,2)     # go to the file end.
eof = f.tell()   # get the end of file location
f.seek(0,0)      # go back to file beginning

while(f.tell() != eof):
    <body>

You can use the file methods seek() and tell() to determine the position of the end of file. Once the position is found, seek back to the file beginning

@html.label and @html.textbox are use when you want bind it to your model in a easy way...which cannot be achieve by input etc. in one line

To fix this issue, I simply let Tortoise Git install its update.

You have to replace string line

QString line = in.readLine();

into while:

QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
    QMessageBox::information(0, "error", file.errorString());
}

QTextStream in(&file);

while(!in.atEnd()) {
    QString line = in.readLine();    
    QStringList fields = line.split(",");    
    model->appendRow(fields);    
}

file.close();

I ended up using this:

$('.selectAll').toggle(function() {
  $(this).select();
}, function() {
  $(this).unselect();
});

Are you using virtualenv? If yes, deactivate the virtualenv. If you are not using, it is already installed widely (system level). Try to upgrade package.

pip install flake8 --upgrade

Press Control + H, then select Options and check Match entire cell contents and Match case. In the Find what field type a 0, and leave the Replace with field blank. Then Replace All. This will remove all of the zeros that are stand alone.

>>> n, m = 6, 3
>>> k = n - m+1
>>> print ('{}\n'*(k)).format(*[range(i, i+m) for i in xrange(k)])

This method Appends the specified element to the end of this list.

add(E e) //append element to the end of the arraylist.

This method Inserts the specified element at the specified position in this list.

void add(int index, E element) //inserts element at the given position in the array list.

This method Replaces the element at the specified position in this list with the specified element.

set(int index, E element) //Replaces the element at the specified position in this list with the specified element.
      

      

Consider the code below.

def return_something(someint):
 if  someint > 5:
    return someint

y = return_something(2)
y.real()

This is going to give you the error

AttributeError: 'NoneType' object has no attribute 'real'

So points are as below.

1. In the code, a function or class method is not returning anything or returning the None
2. Then you try to access an attribute of that returned object(which is None), causing the error message.

After doing some research and testing, the only correct implementation is:

setTimeout(yourFunctionReference, 4000, param1, param2, paramN);

setTimeout will pass all extra parameters to your function so they can be processed there.

The anonymous function can work for very basic stuff, but within instance of a object where you have to use "this", there is no way to make it work. Any anonymous function will change "this" to point to window, so you will lose your object reference.

The best approach to embed a SWF into an HTML page is to use SWFObject.

It is a simple open-source JavaScript library that is easy-to-use and standards-friendly method to embed Flash content.

It also offers Flash player version detection. If the user does not have the version of Flash required or has JavaScript disabled, they will see an alternate content. You can also use this library to trigger a Flash player upgrade. Once the user has upgraded, they will be redirected back to the page.

An example from the documentation:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
  <head>
    <title>SWFObject dynamic embed - step 3</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <script type="text/javascript" src="swfobject.js"></script>

    <script type="text/javascript">
        swfobject.embedSWF("myContent.swf", "myContent", "300", "120", "9.0.0");
    </script>

  </head>
  <body>
    <div id="myContent">
      <p>Alternative content</p>
    </div>
  </body>
</html>

A good tool to use along with this is the SWFObject HTML and JavaScript generator. It basically generates the HTML and JavaScript you need to embed the Flash using SWFObject. Comes with a very simple UI for you to input your parameters.

It Is highly recommended and very simple to use.

1) Add any remote repositories you want to compare:

git remote add foobar git://github.com/user/foobar.git

2) Update your local copy of a remote:

git fetch foobar

Fetch won't change your working copy.

3) Compare any branch from your local repository to any remote you've added:

git diff master foobar/master

my string

var obj = {"Status":0,"Data":{"guid":"","invitationGuid":"","entityGuid":"387E22AD69-4910-430C-AC16-8044EE4A6B24443545DD"},"Extension":null}

Following code to get guid:

var userObj = JObject.Parse(obj);
var userGuid = Convert.ToString(userObj["Data"]["guid"]);

As of Chrome 52, the UI has changed. When the Developer Tools dialog is open, you select the vertical ellipsis and can then choose the docking position:

Select the icon on the left to open the Chrome Developer Tools in a new window:

Previously

Click and hold the button next to the close button of the Developer Tool in order to reveal the "Undock into separate window" option.

Note: A "press" is not enough in that state.

On Linux (at least) you can set CHROME_LOG_FILE in the environment to have chrome write a log of the Console activity to the named file each time it runs. The log is overwritten every time chrome starts. This way, if you have an automated session that runs chrome, you don't have a to change the way chrome is started, and the log is there after the session ends.

export CHROME_LOG_FILE=chrome.log

If you want to test the index to see if it works, here is the syntax:

SELECT *
FROM Table WITH(INDEX(Index_Name))

The WITH statement will force the index to be used.

Add this code in the activity from where you want to exit from the app on pressing back button:

@Override
public void onBackPressed() {
    super.onBackPressed();
    exitFromApp();
}

private void exitFromApp() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    startActivity(intent);
}

Mongo includes a mongoexport utility (see docs) which can dump a collection. This utility uses the native libmongoclient and is likely the fastest method.

mongoexport -d <database> -c <collection_name>

Also helpful:

-o: write the output to file, otherwise standard output is used (docs)

--jsonArray: generates a valid json document, instead of one json object per line (docs)

--pretty: outputs formatted json (docs)

Never, never, never say

if something == True:

Never. It's crazy, since you're redundantly repeating what is redundantly specified as the redundant condition rule for an if-statement.

Worse, still, never, never, never say

if something == False:

You have not. Feel free to use it.

Finally, doing a == None is inefficient. Do a is None. None is a special singleton object, there can only be one. Just check to see if you have that object.

body { 
    min-height: 101vh;

works the best for me

Had similar problem. Added in build.gradle and it worked for me.

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

The following solution worked for me.

I added resetting state function to meta reducers.The key was to use

return reducer(undefined, action);

to set all reducers to initial state. Returning undefined instead was causing errors due to the fact that the structure of the store has been destroyed.

/reducers/index.ts

export function resetState(reducer: ActionReducer<State>): ActionReducer<State> {
  return function (state: State, action: Action): State {

    switch (action.type) {
      case AuthActionTypes.Logout: {
        return reducer(undefined, action);
      }
      default: {
        return reducer(state, action);
      }
    }
  };
}

export const metaReducers: MetaReducer<State>[] = [ resetState ];

app.module.ts

import { StoreModule } from '@ngrx/store';
import { metaReducers, reducers } from './reducers';

@NgModule({
  imports: [
    StoreModule.forRoot(reducers, { metaReducers })
  ]
})
export class AppModule {}

This generates a random number between 0-9

SELECT ABS(CHECKSUM(NEWID()) % 10)

1 through 6

SELECT ABS(CHECKSUM(NEWID()) % 6) + 1

3 through 6

SELECT ABS(CHECKSUM(NEWID()) % 4) + 3

Dynamic (Based on Eilert Hjelmeseths Comment, updated to fix bug( + to -))

SELECT ABS(CHECKSUM(NEWID()) % (@max - @min - 1)) + @min

Updated based on comments:

• NEWID generates random string (for each row in return)
• CHECKSUM takes value of string and creates number
• modulus (%) divides by that number and returns the remainder (meaning max value is one less than the number you use)
• ABS changes negative results to positive
• then add one to the result to eliminate 0 results (to simulate a dice roll)

Happy coding..

The new line character is \n. It is used inside a string.

Example:

    print('First line \n Second line') 

where \n is the newline character.

This would yield the result:

First line
 Second line

If you use Python 2, you do not use the parentheses on the print function.

Hive has a lot of good date parsing UDFs: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-DateFunctions

Just doing the string comparison as Nigel Tufnel suggests is probably the easiest solution, although technically it's unsafe. But you probably don't need to worry about that unless your tables have historical data about the medieval ages (dates with only 3 year digits) or dates from scifi novels (dates with more than 4 year digits).

Anyway, if you ever find yourself in a situation where you would want to do fancier date comparisons, or if your date format is not in a "biggest to smallest" order, e.g. the American convention of "mm/dd/yyyy", then you could use unix_timestamp with two arguments:

select *
from your_table
where unix_timestamp(your_date_column, 'yyyy-MM-dd') >= unix_timestamp('2010-09-01', 'yyyy-MM-dd')
and unix_timestamp(your_date_column, 'yyyy-MM-dd') <= unix_timestamp('2013-08-31', 'yyyy-MM-dd')

If you are given this format it takes like a link to another page or another link.partial view majorly used for renduring the html files from one place to another.

tldr; both HTTP/1.1 and HTTP/2 headers are case-insensitive.

According to RFC 7230 (HTTP/1.1):

Each header field consists of a case-insensitive field name followed by a colon (":"), optional leading whitespace, the field value, and optional trailing whitespace.

https://tools.ietf.org/html/rfc7230#section-3.2

Also, RFC 7540 (HTTP/2):

Just as in HTTP/1.x, header field names are strings of ASCII
characters that are compared in a case-insensitive fashion.

I struggled for half a day to get JSCH to work without using the System.in as the input stream to no avail. I tried Ganymed http://www.ganymed.ethz.ch/ssh2/ and had it going in 5 minutes. All the examples seem to be aimed at one usage of the app and none of the examples showed what i needed. Ganymed's example Basic.java Baaaboof Has everything i need.

:qall and :wqall to close all the split screens.

Interestingly, when I replaced this:

$("body").trigger("click")

With this:

jQuery("body").trigger("click")

It works!

In WPF an image is typically loaded from a Stream or an Uri.

BitmapImage supports both and an Uri can even be passed as constructor argument:

var uri = new Uri("http://...");
var bitmap = new BitmapImage(uri);

If the image file is located in a local folder, you would have to use a file:// Uri. You could create such a Uri from a path like this:

var path = Path.Combine(Environment.CurrentDirectory, "Bilder", "sas.png");
var uri = new Uri(path);

If the image file is an assembly resource, the Uri must follow the the Pack Uri scheme:

var uri = new Uri("pack://application:,,,/Bilder/sas.png");

In this case the Visual Studio Build Action for sas.png would have to be Resource.

Once you have created a BitmapImage and also have an Image control like in this XAML

<Image Name="image1" />

you would simply assign the BitmapImage to the Source property of that Image control:

image1.Source = bitmap;

This is how you link a JS file in HTML

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

<script> - tag is used to define a client-side script, such as a JavaScript.

type - specify the type of the script

src - script file name and path

Well, longs can't hold anything but integers.

One option is to use a float: float('234.89')

The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))

>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L

Found transport-attribute in binding-element which tells us that this is the WSDL 1.1 binding for the SOAP 1.1 HTTP binding.

ex.

<wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

As from Android developer guide :

"orientation" The screen orientation has changed — the user has rotated the device. Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.

"screenSize" The current available screen size has changed. This represents a change in the currently available size, relative to the current aspect ratio, so will change when the user switches between landscape and portrait. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device). Added in API level 13.

So, in the AndroidManifest.xml file, we can put:

<activity
            android:name=".activities.role_activity.GeneralViewPagerActivity"
            android:label="@string/title_activity_general_view_pager"
            android:screenOrientation="portrait"
            android:configChanges="orientation|keyboardHidden|screenSize"
            >
        </activity> 

You can try settings of code::block, there is a complier..., then you select in C mode.

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

For Kotlin users:

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?, 
    savedInstanceState: Bundle?) : View?
{
    // Inflate the layout for this fragment
    var myView = inflater.inflate(R.layout.fragment_home, container, false)
    var btn_test = myView.btn_test as Button
    btn_test.setOnClickListener {
        textView.text = "hunny home fragment"
    }

    return myView
}

In case you want to pass multiple arguments you can use a tuple

price = 33.3
with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: %s price %f" % (TotalAmount, price))

More: Print multiple arguments in python

if you want to print the value of a size_t as a string you can do this:

char text[] = "Lets go fishing in stead of sitting on our but !!";
size_t line = 2337200120702199116;

/* on windows I64x or I64d others %lld or %llx if it works %zd or %zx */
printf("number: %I64d\n",*(size_t*)&text);
printf("text: %s\n",*(char(*)[])&line);

result is:

number: 2337200120702199116

text: Lets go fishing in stead of sitting on our but !!

Edit: rereading the question because of the down votes i noted his problem is not %llu or %I64d but the size_t type on different machines see this question https://stackoverflow.com/a/918909/1755797
http://www.cplusplus.com/reference/cstdio/printf/

size_t is unsigned int on a 32bit machine and unsigned long long int on 64bit
but %ll always expects a unsigned long long int.

size_t varies in length on different operating systems while %llu is the same

Also with indented source code you can use <<- (with a trailing dash) to ignore leading tabs (but not leading spaces).

For example this:

if [ some test ]; then
    cat <<- xx
        line1
        line2
xx
fi

Outputs indented text without the leading whitespace:

line1
line2

You can achieve it using this single line code :

String numbers = text.substring(text.length() - 7, text.length());

But be sure to catch Exception if the input string length is less than 7.

You can replace 7 with any number say N, if you want to get last 'N' characters.

To install 3.0 which is the latest stable version:

$ git clone http://github.com/antirez/redis.git 
$ cd redis && git checkout 3.0 
$ make redis-cli 

Optionally, you can put the compiled executable in your load path for convenience:

$ ln -s src/redis-cli /usr/local/bin/redis-cli

If you want to use jQuery on a site where it is already included, this is the way to go (inspired by BrunoLM):

var $ = unsafeWindow.jQuery;

I know this wasn't the original intent of the question, but it is increasingly becoming a common case and you didn't explicitly exclude this case. ;)

I liked galloglas's code, and I changed the main function so that it shows a sorted list of total size by application:

verbose = True
if __name__ == '__main__':
    mbdb = process_mbdb_file("Manifest.mbdb")
    mbdx = process_mbdx_file("Manifest.mbdx")
    sizes = {}
    for offset, fileinfo in mbdb.items():
        if offset in mbdx:
            fileinfo['fileID'] = mbdx[offset]
        else:
            fileinfo['fileID'] = "<nofileID>"
            print >> sys.stderr, "No fileID found for %s" % fileinfo_str(fileinfo)
        print fileinfo_str(fileinfo, verbose)
        if (fileinfo['mode'] & 0xE000) == 0x8000:
        sizes[fileinfo['domain']]= sizes.get(fileinfo['domain'],0) + fileinfo['filelen']
    for domain in sorted(sizes, key=sizes.get):
        print "%-60s %11d (%dMB)" % (domain, sizes[domain], int(sizes[domain]/1024/1024))

That way you can figure out what application is eating all that space.

You can use Files#readAllLines() to get all lines of a text file into a List<String>.

for (String line : Files.readAllLines(Paths.get("/path/to/file.txt"))) {
    // ...
}

Tutorial: Basic I/O > File I/O > Reading, Writing and Creating text files

You can use String#split() to split a String in parts based on a regular expression.

for (String part : line.split("\\s+")) {
    // ...
}

Tutorial: Numbers and Strings > Strings > Manipulating Characters in a String

You can use Integer#valueOf() to convert a String into an Integer.

Integer i = Integer.valueOf(part);

Tutorial: Numbers and Strings > Strings > Converting between Numbers and Strings

You can use List#add() to add an element to a List.

numbers.add(i);

Tutorial: Interfaces > The List Interface

So, in a nutshell (assuming that the file doesn't have empty lines nor trailing/leading whitespace).

List<Integer> numbers = new ArrayList<>();
for (String line : Files.readAllLines(Paths.get("/path/to/file.txt"))) {
    for (String part : line.split("\\s+")) {
        Integer i = Integer.valueOf(part);
        numbers.add(i);
    }
}

If you happen to be at Java 8 already, then you can even use Stream API for this, starting with Files#lines().

List<Integer> numbers = Files.lines(Paths.get("/path/to/test.txt"))
    .map(line -> line.split("\\s+")).flatMap(Arrays::stream)
    .map(Integer::valueOf)
    .collect(Collectors.toList());

For Windows' IDE:

If your path doesn't work, you can try to add the chromedriver.exe to your project, like in this project structure.

Then you should load the chromedriver.exe in your main file. As for me, I loaded the driver.exe in driver.py.

def get_chrome_driver():
return webdriver.Chrome("..\\content\\engine\\chromedriver.exe",
                            chrome_options='--no-startup-window')

.. means driver.py's upper directory

. means the directory where the driver.py is located

Hope this will be helpful.

If you want to apply the WHERE clause to the result of the UNION, then you have to embed the UNION in the FROM clause:

SELECT *
  FROM (SELECT * FROM TableA
        UNION
        SELECT * FROM TableB
       ) AS U
 WHERE U.Col1 = ...

I'm assuming TableA and TableB are union-compatible. You could also apply a WHERE clause to each of the individual SELECT statements in the UNION, of course.

If you want to do it in shell, instead of writing code.

 python3 -m zipfile -e myfiles.zip myfiles/

myfiles.zip is the zip archive and myfiles is the path to extract the files.

I think there is a specific Win32 API call which takes the application path and puts it in the registry automatically for you in the proper location, I've used it in the past but I don't remember the function name anymore.

I've never come across point 2? Can you explain why you think this affects deployment in any way. If anything maven allows you to structure your projects in a modularised way that actually allows hot fixes for bugs in a particular tier, and allows independent development of an API from the remainder of the project for example.

It is possible that you are trying to cram everything into a single module, in which case the problem isn't really maven at all, but the way you are using it.

2018 Update

In the current version of PowerShell (tested with v5.1 on Windows 10 1809) one can use the simpler Unix syntax rm -R .\DirName to silently delete the directory .\DirName with all subdirectories and files it may contain. In fact many common Unix commands work in the same way in PowerShell as in a Linux command line.

datejs could parse following, you might want to try out.

Date.parse('1997-07-16T19:20:15')           // ISO 8601 Formats
Date.parse('1997-07-16T19:20:30+01:00')     // ISO 8601 with Timezone offset

Edit: Regex version

x = "2011-01-28T19:30:00EST"

MM = ["January", "February","March","April","May","June","July","August","September","October","November", "December"]

xx = x.replace(
    /(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):\d{2}(\w{3})/,
    function($0,$1,$2,$3,$4,$5,$6){
        return MM[$2-1]+" "+$3+", "+$1+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6
    }
)

Result

January 28, 2011 - 7:30PM EST

Edit2: I changed my timezone to EST and now I got following

x = "2011-01-28T19:30:00-05:00"

MM = {Jan:"January", Feb:"February", Mar:"March", Apr:"April", May:"May", Jun:"June", Jul:"July", Aug:"August", Sep:"September", Oct:"October", Nov:"November", Dec:"December"}

xx = String(new Date(x)).replace(
    /\w{3} (\w{3}) (\d{2}) (\d{4}) (\d{2}):(\d{2}):[^(]+\(([A-Z]{3})\)/,
    function($0,$1,$2,$3,$4,$5,$6){
        return MM[$1]+" "+$2+", "+$3+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6 
    }
)

return

January 28, 2011 - 7:30PM EST

Basically

String(new Date(x))

return

Fri Jan 28 2011 19:30:00 GMT-0500 (EST)

I disagree with the advice given here - even the reference for the accepted answer concludes:

You can of course use query string parameters with HTTPS, but don’t use them for anything that could present a security problem. For example, you could safely use them to identity part numbers or types of display like ‘accountview’ or ‘printpage’, but don’t use them for passwords, credit card numbers or other pieces of information that should not be publicly available.

So, no they aren't really safe...!

In C++ (but not plain C), it's perfectly legal to typedef a type twice, so long as both definitions are completely identical:

// foo.h
struct A{};
typedef A *PA;

// bar.h
struct A;  // forward declare A
typedef A *PA;
void func(PA x);

// baz.cc
#include "bar.h"
#include "foo.h"
// We've now included the definition for PA twice, but it's ok since they're the same
...
A x;
func(&x);

This is an old topic, but I wrote a class with nested subclasses and static members for colors defined by simple C macros.

I got the color function from this post Color Text In C Programming in dreamincode.net by user no2pencil.

I made it this way so to be able to use the static constants in std::cout stream like this:

cout << zkr::cc::fore::red << "This is red text. " 
     << zkr::cc::console << "And changing to console default colors, fg, bg."
     << endl;

The class and a test program source code can be downloaded here.

cc::console will reset to console default colors and attributes, cc::underline will underline the text, which works on putty which I've tested the test program.

Colors:

black
blue
red
magenta
green
cyan
yellow
white

lightblack
lightblue
lightred
lightmagenta
lightgreen
lightcyan
lightyellow
lightwhite

Which can be used with both fore and back static subclasses of the cc static class.

EDIT 2017

I'm just adding the class code here to be more practical.

The color code macros:

#define CC_CONSOLE_COLOR_DEFAULT "\033[0m"
#define CC_FORECOLOR(C) "\033[" #C "m"
#define CC_BACKCOLOR(C) "\033[" #C "m"
#define CC_ATTR(A) "\033[" #A "m"

and the main color function that defines a color or an attribute to the screen:

char *cc::color(int attr, int fg, int bg)
{
    static char command[13];

    /* Command is the control command to the terminal */
    sprintf(command, "%c[%d;%d;%dm", 0x1B, attr, fg + 30, bg + 40);
    return command;
}

You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %> with its successor EL ${}. They do not share the same variable scope. The allFestivals is not available in scriptlet scope and the i is not available in EL scope.

You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

and then iterate over the list as follows:

<c:forEach items="${allFestivals}" var="festival">
    <tr>      
        <td>${festival.festivalName}</td>
        <td>${festival.location}</td>
        <td>${festival.startDate}</td>
        <td>${festival.endDate}</td>
        <td>${festival.URL}</td>  
    </tr>
</c:forEach>

(beware of possible XSS attack holes, use <c:out> accordingly)

Don't forget to remove the <jsp:useBean> as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml so that you won't accidently use them:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <scripting-invalid>true</scripting-invalid>
    </jsp-property-group>
</jsp-config>

Node.js was created explicitly as an experiment in async processing. The theory was that doing async processing on a single thread could provide more performance and scalability under typical web loads than the typical thread-based implementation.

And you know what? In my opinion that theory's been borne out. A node.js app that isn't doing CPU intensive stuff can run thousands more concurrent connections than Apache or IIS or other thread-based servers.

The single threaded, async nature does make things complicated. But do you honestly think it's more complicated than threading? One race condition can ruin your entire month! Or empty out your thread pool due to some setting somewhere and watch your response time slow to a crawl! Not to mention deadlocks, priority inversions, and all the other gyrations that go with multithreading.

In the end, I don't think it's universally better or worse; it's different, and sometimes it's better and sometimes it's not. Use the right tool for the job.

I found out that you need to add the pointer eg:

div{
    cursor: url('cursorurl.png'), pointer;
}

window.open('mailto:[email protected]'); as above does nothing to hide the "[email protected]" email address from being harvested by spambots. I used to constantly run into this problem.

var recipient="test";
var at = String.fromCharCode(64);
var dotcom="example.com";
var mail="mailto:";
window.open(mail+recipient+at+dotcom);

• fill_parent will make the width or height of the element to be as large as the parent element, in other words, the container.

• wrap_content will make the width or height be as large as needed to contain the elements within it.

I don't know you specific situation. Back when I was writing C programs, we have always used #2.

#define FALSE = 0
#define TRUE = !FALSE

This might be otherwise under alien platform to DOS or Intel-based processors. But I used to use both C and ASM together writing graphic libraries and graphical IDE. I was a true fan of Micheal Abrash and was intending to learn about texture mapping and so. Anyway! That's not the subject of the question here!

This was the most commonly used form to define boolean values in C, as this headerfile stdbool.h did not exist then.

Both directives obviously serve the same purpose, and though it seems that the decision of the angular team to include both interfere with the DRY principle and adds to the payload of the page, it still is rather practical to have them both around. It is easier to style your input elements as you have both .ng-pristine and .ng-dirty available for styling in your css files. I guess this was the primary reason for adding both directives.

Looping through a table for each row and reading the 1st column value works by using JQuery and DOM logic.

var i = 0;
var t = document.getElementById('flex1');

$("#flex1 tr").each(function() {
    var val1 = $(t.rows[i].cells[0]).text();
    alert(val1) ;
    i++;
});

Try this

Months.values()[index]

This way of specifying the encoding of a Python file comes from PEP 0263 - Defining Python Source Code Encodings.

It is also recognized by GNU Emacs (see Python Language Reference, 2.1.4 Encoding declarations), though I don't know if it was the first program to use that syntax.

I'm using such thing to clean-up the style='...' section out of tags with keeping of other attributes at the moment.

$output = preg_replace('/<([^>]+)(\sstyle=(?P<stq>["\'])(.*)\k<stq>)([^<]*)>/iUs', '<$1$5>', $input);

Try installing it again with the stand alone installer https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager-end-user-license-agreement - assuming you have a CPU that supports Virtualization, have turned off antivirus and any hypervisor.

If you just happen to have a Map with Integer keys you cannot change, you could write a custom EL function to convert a Long to Integer. This would allow you to do something like:

<c:out value="${map[myLib:longToInteger(1)]}"/>

It seems that with ASP.NET Core 2, you can again inherit AuthorizeAttribute, you just need to also implement IAuthorizationFilter (or IAsyncAuthorizationFilter):

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class CustomAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    private readonly string _someFilterParameter;

    public CustomAuthorizeAttribute(string someFilterParameter)
    {
        _someFilterParameter = someFilterParameter;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;

        if (!user.Identity.IsAuthenticated)
        {
            // it isn't needed to set unauthorized result 
            // as the base class already requires the user to be authenticated
            // this also makes redirect to a login page work properly
            // context.Result = new UnauthorizedResult();
            return;
        }

        // you can also use registered services
        var someService = context.HttpContext.RequestServices.GetService<ISomeService>();

        var isAuthorized = someService.IsUserAuthorized(user.Identity.Name, _someFilterParameter);
        if (!isAuthorized)
        {
            context.Result = new StatusCodeResult((int)System.Net.HttpStatusCode.Forbidden);
            return;
        }
    }
}

JPA is just a specification while Hibernate is one of the JPA provider i.e hibernate is implementing various things mentioned in JPA contract.

I did a function that takes array of strings and returns attributed string with the attributes you give.

func createAttributedString(stringArray: [String], attributedPart: Int, attributes: [NSAttributedString.Key: Any]) -> NSMutableAttributedString? {
    let finalString = NSMutableAttributedString()
    for i in 0 ..< stringArray.count {
        var attributedString = NSMutableAttributedString(string: stringArray[i], attributes: nil)
        if i == attributedPart {
            attributedString = NSMutableAttributedString(string: attributedString.string, attributes: attributes)
            finalString.append(attributedString)
        } else {
            finalString.append(attributedString)
        }
    }
    return finalString
}

In the example above you specify what part of string you want to get attributed with attributedPart: Int

And then you give the attributes for it with attributes: [NSAttributedString.Key: Any]

USE EXAMPLE

if let attributedString = createAttributedString(stringArray: ["Hello ", "how ", " are you?"], attributedPart: 2, attributes: [NSAttributedString.Key.foregroundColor: UIColor.systemYellow]) {
      myLabel.attributedText = attributedString
}

For me, a hint to wrap the troubled element in another HTML tag helped. However I also needed to add a key to that HTML tag. For example:

// Didn't work
<div>
     <TroubledComponent/>
</div>

// Worked
<div key='uniqueKey'>
     <TroubledComponent/>
</div>

Procedures in a Module start being useful and generic when you pass in arguments.

For example:

Public Function DoSomethingElse(strMessage As String)  
    MsgBox strMessage
End Function

Can now display any message that is passed in with the string variable called strMessage.

A nice practical use of this is if you want to make your own HtmlHelper extensions. For example, I hate trying to remember the <link> tag syntax, so I've created my own extension method to make a <link> tag:

<Extension()> _
Public Function CssBlock(ByVal html As HtmlHelper, ByVal src As String, ByVal Optional ByVal htmlAttributes As Object = Nothing) As MvcHtmlString
    Dim tag = New TagBuilder("link")
    tag.MergeAttribute("type", "text/css")
    tag.MergeAttribute("rel", "stylesheet")
    tag.MergeAttribute("href", src)
    tag.MergeAttributes(New RouteValueDictionary(htmlAttributes))
    Dim result = tag.ToString(TagRenderMode.Normal)
    Return MvcHtmlString.Create(result)
End Function

I could have returned String from this method, but if I had the following would break:

<%: Html.CssBlock(Url.Content("~/sytles/mysite.css")) %>

With MvcHtmlString, using either <%: ... %> or <%= ... %> will both work correctly.

That is the correct way to do it till such a component (or attribute on the TextInput) is specifically developed.

The web has the ‘number’ type for the input element, but that is web based and react-native does not use a web view.

You could consider to create that input as a react component on it’s own (maybe call NumberInput): that’ll enable you to reuse it or maybe even open source it since you can create many TextInputs that has different value filters/checkers.

The downside to immediate correction is to ensure correct feedback is given to the user as to prevent confusion as to what happened to his value

select t1.* from 
(select * from TABLE Where CCC='D' AND DDD='X') as t1,
(select * from TABLE Where CCC<>'D' AND DDD='X') as t2

Another way to do this!

Typically you'll need cookies to log into a site, which means cookielib, urllib and urllib2. Here's a class which I wrote back when I was playing Facebook web games:

import cookielib
import urllib
import urllib2

# set these to whatever your fb account is
fb_username = "[email protected]"
fb_password = "secretpassword"

class WebGamePlayer(object):

    def __init__(self, login, password):
        """ Start up... """
        self.login = login
        self.password = password

        self.cj = cookielib.CookieJar()
        self.opener = urllib2.build_opener(
            urllib2.HTTPRedirectHandler(),
            urllib2.HTTPHandler(debuglevel=0),
            urllib2.HTTPSHandler(debuglevel=0),
            urllib2.HTTPCookieProcessor(self.cj)
        )
        self.opener.addheaders = [
            ('User-agent', ('Mozilla/4.0 (compatible; MSIE 6.0; '
                           'Windows NT 5.2; .NET CLR 1.1.4322)'))
        ]

        # need this twice - once to set cookies, once to log in...
        self.loginToFacebook()
        self.loginToFacebook()

    def loginToFacebook(self):
        """
        Handle login. This should populate our cookie jar.
        """
        login_data = urllib.urlencode({
            'email' : self.login,
            'pass' : self.password,
        })
        response = self.opener.open("https://login.facebook.com/login.php", login_data)
        return ''.join(response.readlines())

You won't necessarily need the HTTPS or Redirect handlers, but they don't hurt, and it makes the opener much more robust. You also might not need cookies, but it's hard to tell just from the form that you've posted. I suspect that you might, purely from the 'Remember me' input that's been commented out.

Update September 2015 (6 years later)

The last release of git-for-Windows (2.5.3) now includes:

By configuring git config core.editor notepad, users can now use notepad.exe as their default editor.
Configuring git config format.commitMessageColumns 72 will be picked up by the notepad wrapper and line-wrap the commit message after the user edits it.

See commit 69b301b by Johannes Schindelin (dscho).

And Git 2.16 (Q1 2018) will show a message to tell the user that it is waiting for the user to finish editing when spawning an editor, in case the editor opens to a hidden window or somewhere obscure and the user gets lost.

See commit abfb04d (07 Dec 2017), and commit a64f213 (29 Nov 2017) by Lars Schneider (larsxschneider).

launch_editor(): indicate that Git waits for user input

When a graphical GIT_EDITOR is spawned by a Git command that opens and waits for user input (e.g. "git rebase -i"), then the editor window might be obscured by other windows.
The user might be left staring at the original Git terminal window without even realizing that s/he needs to interact with another window before Git can proceed. To this user Git appears hanging.

Print a message that Git is waiting for editor input in the original terminal and get rid of it when the editor returns, if the terminal supports erasing the last line

Original answer

I just tested it with git version 1.6.2.msysgit.0.186.gf7512 and Notepad++5.3.1

I prefer to not have to set an EDITOR variable, so I tried:

git config --global core.editor "\"c:\Program Files\Notepad++\notepad++.exe\""
# or
git config --global core.editor "\"c:\Program Files\Notepad++\notepad++.exe\" %*"

That always gives:

C:\prog\git>git config --global --edit
"c:\Program Files\Notepad++\notepad++.exe" %*: c:\Program Files\Notepad++\notepad++.exe: command not found
error: There was a problem with the editor '"c:\Program Files\Notepad++\notepad++.exe" %*'.

If I define a npp.bat including:

"c:\Program Files\Notepad++\notepad++.exe" %*

and I type:

C:\prog\git>git config --global core.editor C:\prog\git\npp.bat

It just works from the DOS session, but not from the git shell.
(not that with the core.editor configuration mechanism, a script with "start /WAIT..." in it would not work, but only open a new DOS window)

Bennett's answer mentions the possibility to avoid adding a script, but to reference directly the program itself between simple quotes. Note the direction of the slashes! Use / NOT \ to separate folders in the path name!

git config --global core.editor \
"'C:/Program Files/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"

Or if you are in a 64 bit system:

git config --global core.editor \
"'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"

But I prefer using a script (see below): that way I can play with different paths or different options without having to register again a git config.

The actual solution (with a script) was to realize that:
what you refer to in the config file is actually a shell (/bin/sh) script, not a DOS script.

So what does work is:

C:\prog\git>git config --global core.editor C:/prog/git/npp.bat

with C:/prog/git/npp.bat:

#!/bin/sh
"c:/Program Files/Notepad++/notepad++.exe" -multiInst "$*"

or

#!/bin/sh
"c:/Program Files/Notepad++/notepad++.exe" -multiInst -notabbar -nosession -noPlugin "$*"

With that setting, I can do 'git config --global --edit' from DOS or Git Shell, or I can do 'git rebase -i ...' from DOS or Git Shell.
Bot commands will trigger a new instance of notepad++ (hence the -multiInst' option), and wait for that instance to be closed before going on.

Note that I use only '/', not \'. And I installed msysgit using option 2. (Add the git\bin directory to the PATH environment variable, but without overriding some built-in windows tools)

The fact that the notepad++ wrapper is called .bat is not important.
It would be better to name it 'npp.sh' and to put it in the [git]\cmd directory though (or in any directory referenced by your PATH environment variable).

lightfire228 adds in the comments:

For anyone having an issue where N++ just opens a blank file, and git doesn't take your commit message, see "Aborting commit due to empty message": change your .bat or .sh file to say:

"<path-to-n++" .git/COMMIT_EDITMSG -<arguments>. 

That will tell notepad++ to open the temp commit file, rather than a blank new one.

Yes. Problem is in wrong notation. Use:

$this->sendRequest($uri)

Instead. Or

self::staticMethod()

for static methods. Also read this for getting idea of OOP - http://www.php.net/manual/en/language.oop5.basic.php

I found this question while trying to figure out why I could not connect to redis after starting it via brew services start redis.

tl;dr

Depending on how fresh your machine or install is you're likely missing a config file or a directory for the redis defaults.

1. You need a config file at /usr/local/etc/redis.conf. Without this file redis-server will not start. You can copy over the default config file and modify it from there with

   cp /usr/local/etc/redis.conf.default /usr/local/etc/redis.conf
   

2. You need /usr/local/var/db/redis/ to exist. You can do this easily with

   mkdir -p /usr/local/var/db/redis
   

Finally just restart redis with brew services restart redis.

How do you find this out!?

I wasted a lot of time trying to figure out if redis wasn't using the defaults through homebrew and what port it was on. Services was misleading because even though redis-server had not actually started, brew services list would still show redis as "started." The best approach is to use brew services --verbose start redis which will show you that the log file is at /usr/local/var/log/redis.log. Looking in there I found the smoking gun(s)

Fatal error, can't open config file '/usr/local/etc/redis.conf'

or

Can't chdir to '/usr/local/var/db/redis/': No such file or directory

Thankfully the log made the solution above obvious.

Can't I just run redis-server?

You sure can. It'll just take up a terminal or interrupt your terminal occasionally if you run redis-server &. Also it will put dump.rdb in whatever directory you run it in (pwd). I got annoyed having to remove the file or ignore it in git so I figured I'd let brew do the work with services.

If your table is only 2 columns across, you can easily reach the second td with the adjacent sibling selector, which IE8 does support along with :first-child:

.editor td:first-child
{
    width: 150px; 
}

.editor td:first-child + td input,
.editor td:first-child + td textarea
{
    width: 500px;
    padding: 3px 5px 5px 5px;
    border: 1px solid #CCC; 
}

Otherwise, you'll have to use a JS selector library like jQuery, or manually add a class to the last td, as suggested by James Allardice.

You can also drag a tap gesture recogniser to the image view in Storyboard. Then create an action by ctrl + drag to the code.

range = 10..50

rand(range)

or

range.to_a.sample

or

range.to_a.shuffle(this will shuffle whole array and you can pick a random number by first or last or any from this array to pick random one)

Try to use this alternate query:

SELECT A.CONTACTID 
FROM (SELECT CONTACTID FROM TESTTBL WHERE FLAG = 'VOLUNTEER')A , 
(SELECT CONTACTID FROM TESTTBL WHERE FLAG = 'UPLOADED') B WHERE A.CONTACTID = B.CONTACTID;

Here is a generic solution using plpgsql:

CREATE OR REPLACE FUNCTION create_role_if_not_exists(rolename NAME) RETURNS TEXT AS
$$
BEGIN
    IF NOT EXISTS (SELECT * FROM pg_roles WHERE rolname = rolename) THEN
        EXECUTE format('CREATE ROLE %I', rolename);
        RETURN 'CREATE ROLE';
    ELSE
        RETURN format('ROLE ''%I'' ALREADY EXISTS', rolename);
    END IF;
END;
$$
LANGUAGE plpgsql;

Usage:

posgres=# SELECT create_role_if_not_exists('ri');
 create_role_if_not_exists 
---------------------------
 CREATE ROLE
(1 row)
posgres=# SELECT create_role_if_not_exists('ri');
 create_role_if_not_exists 
---------------------------
 ROLE 'ri' ALREADY EXISTS
(1 row)

This can't be done with pure HTML.

However if you have access to PHP on the Apache server (you tagged the post "apache") it can be done easilly - se the PHP glob function. If not - you might try Server Side Include - it's an Apache thing, and I don't know much about it.

Answers above helped greatly.

Here is the Swift version.

@IBOutlet weak var priceLabel: UILabel!

*.... lines of code later*

self.priceLabel.font = self.priceLabel.font.fontWithSize(22)

Everybody did explain why this problem occurs, but it's still very easy to forget about it and then scratching your head why you got wrong results. Especially when you're working on big sets of data when the results seem to be fine at first glance.

Using Object.entries you ensure to go trough all properties:

var arr = [3, 5, 7];
arr.foo = "hello";

for ( var [key, val] of Object.entries( arr ) ) {
   console.log( val );
}

/* Result:

3
5
7
hello

*/

If you need to remove just trailing whitespace, you could use str.rstrip(), which should be slightly more efficient than str.strip():

>>> lst = ['this\n', 'is\n', 'a\n', 'list\n', 'of\n', 'words\n']
>>> [x.rstrip() for x in lst]
['this', 'is', 'a', 'list', 'of', 'words']
>>> list(map(str.rstrip, lst))
['this', 'is', 'a', 'list', 'of', 'words']

A more native pandas approach is to apply a replace function as below:

def multiple_replace(dict, text):
  # Create a regular expression  from the dictionary keys
  regex = re.compile("(%s)" % "|".join(map(re.escape, dict.keys())))

  # For each match, look-up corresponding value in dictionary
  return regex.sub(lambda mo: dict[mo.string[mo.start():mo.end()]], text) 

Once you defined the function, you can apply it to your dataframe.

di = {1: "A", 2: "B"}
df['col1'] = df.apply(lambda row: multiple_replace(di, row['col1']), axis=1)

Agree with Dave Webb, os.walk will yield an item for each directory in the tree. Fact is, you just don't have to care about subFolders.

Code like this should work:

import os
import sys

rootdir = sys.argv[1]

for folder, subs, files in os.walk(rootdir):
    with open(os.path.join(folder, 'python-outfile.txt'), 'w') as dest:
        for filename in files:
            with open(os.path.join(folder, filename), 'r') as src:
                dest.write(src.read())

Initial Check.

1) When you are exporting the DISPLAY to other machine, ensure you entered the command xhost + on that machine. This command allows to other machine to export their DISPLAY on this machine. There may be security constraints, just know about it. Need to check ssh -X MachineIP will not require xhost + ?

2) Some times JCONSOLE won't show all its process, since those JVM process may run with different user and you are exporting the DISPLAY with another user. so better follow CD_DIR>sudo ./jconsole

3) In WAS (WEBSPHERE); jconsole won't be able to connect its java server process, that time just go till the link, then try connecting it. This worked for me. May be this page is initializing some variables to enable jconsole to connect with that server.

WAS console > Application servers > server1 > Process definition > Java Virtual Machine

I have faced the same issue with AIX (where command line interface only available, There is no DISPLAY UI) machine. I resolved by installing

NX Client for Windows

Step 1: Through that Windows machine, I connected with unix box where GUI console is available.
Step 2: SSH to the AIX box from that UNIX box.
Step 3: set DISPLAY like "export DISPLAY=UNIXMACHINE:NXClientPORTConnectedMentionedOnTitle"
Step 4: Now if we launch any programs which requires DISPLAY; it will be launched on this UNIX box.

VNC

If you installed VNC on UNIX box where display is available; then Windows and NX Client is not required. Step 1: Use VNC to connect with Unix box where GUI console is available.
Step 2: SSH to the AIX box from that UNIX box.
Step 3: set DISPLAY like "export DISPLAY=UNIXMACHINE:VNCPORT"
Step 4: Now if we launch any programs which requires DISPLAY; it will be launched on this UNIX box.

ELSE

Step 1: SSH to the AIX box from that UNIX box.
Step 2: set DISPLAY like "export DISPLAY=UNIXMACHINE:VNCPORT"
Step 3: Now if we launch any programs which requires DISPLAY; it will be launched on this UNIX box.

Go to Window → Preferences → Java → Installed JREs. Select the JRE you're using, click Edit, and there will be a line for Default VM Arguments which will apply to every execution. For instance, I use this on OS X to hide the icon from the dock, increase max memory and turn on assertions:

-Xmx512m -ea -Djava.awt.headless=true

Have you tried displaying a £ ?

Here is an overwhelming list.

To add to the answers of Ryley and atonyc, you don't actually have to use a real CSS property, like text-index or border-spacing, but instead you can specify a fake CSS property, like rotation or my-awesome-property. It might be a good idea to use something that does not risk becoming an actual CSS property in the future.

Also, somebody asked how to animate other things at the same time. This can be done as usual, but remember that the step function is called for every animated property, so you'll have to check for your property, like so:

$('#foo').animate(
    {
        opacity: 0.5,
        width: "100px",
        height: "100px",
        myRotationProperty: 45
    },
    {
        step: function(now, tween) {
            if (tween.prop === "myRotationProperty") {
                $(this).css('-webkit-transform','rotate('+now+'deg)');
                $(this).css('-moz-transform','rotate('+now+'deg)'); 
                // add Opera, MS etc. variants
                $(this).css('transform','rotate('+now+'deg)');  
            }
        }
    });

(Note: I can't find the documentation for the "Tween" object in the jQuery documentation; from the animate documentation page there is a link to http://api.jquery.com/Types#Tween which is a section that doesn't appear to exist. You can find the code for the Tween prototype on Github here).

This is my simplified example of how to run RAW SELECT, get result and access the values.

$res = DB::select('
        select count(id) as c
        from prices p 
        where p.type in (2,3)
    ');
    if ($res[0]->c > 10)
    {
        throw new Exception('WOW');
    }

If you want only run sql script with no return resutl use this

DB::statement('ALTER TABLE products MODIFY COLUMN physical tinyint(1) AFTER points;');

Tested in laravel 5.1

Java 8 does bring the

Collectors.joining(CharSequence delimiter, CharSequence prefix, CharSequence suffix)

method, that is nullsafe by using prefix + suffix for null values.

It can be used in the following manner:

String s = stringList.stream().collect(Collectors.joining(" and ", "prefix_", "_suffix"))

The Collectors.joining(CharSequence delimiter) method just calls joining(delimiter, "", "") internally.

for (int i = 0; i < myList.Length; i++)
{
    if (myList[i].Contains(myString)) // (you use the word "contains". either equals or indexof might be appropriate)
    {
        return i;
    }
}

Old fashion loops are almost always the fastest.

I had the same problem, and found the answer. If you use node.js with express, you need to give it its own function in order for the js file to be reached. For example:

const script = path.join(__dirname, 'script.js');
const server = express().get('/', (req, res) => res.sendFile(script))

The solution:

error : The requested URL returned error : 503 while Accessing

The error might be resolved by deleting the existing git folder.

Retrieve the ID of the current item in the WordPress Loop.

echo get_the_ID(); 

hence works for the product id too. #tested #woo-commerce

I struggled with the same problem where I was trying to execute an update query like the same as you did-

@Modifying
@Transactional
@Query(value = "UPDATE SAMPLE_TABLE st SET st.status=:flag WHERE se.referenceNo in :ids")
public int updateStatus(@Param("flag")String flag, @Param("ids")List<String> references);

This will work if you have put @EnableTransactionManagement annotation on the main class. Spring 3.1 introduces the @EnableTransactionManagement annotation to be used in on @Configuration classes and enable transactional support.

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

Short answer:

In common use, space " ", Tab "\t" and newline "\n" are the difference:

string.IsNullOrWhiteSpace("\t"); //true
string.IsNullOrEmpty("\t"); //false

string.IsNullOrWhiteSpace(" "); //true
string.IsNullOrEmpty(" "); //false

string.IsNullOrWhiteSpace("\n"); //true
string.IsNullOrEmpty("\n"); //false

Get directory size

Properties of the solution:

• returns both: the apparent size (number of bytes in the file) and the actual disk space the files uses.
• counts hard linked files only once
• counts symlinks the same way du does
• does not use recursion
• uses st.st_blocks for disk space used, thus works only on Unix-like systems

The code:

import os


def du(path):
    if os.path.islink(path):
        return (os.lstat(path).st_size, 0)
    if os.path.isfile(path):
        st = os.lstat(path)
        return (st.st_size, st.st_blocks * 512)
    apparent_total_bytes = 0
    total_bytes = 0
    have = []
    for dirpath, dirnames, filenames in os.walk(path):
        apparent_total_bytes += os.lstat(dirpath).st_size
        total_bytes += os.lstat(dirpath).st_blocks * 512
        for f in filenames:
            fp = os.path.join(dirpath, f)
            if os.path.islink(fp):
                apparent_total_bytes += os.lstat(fp).st_size
                continue
            st = os.lstat(fp)
            if st.st_ino in have:
                continue  # skip hardlinks which were already counted
            have.append(st.st_ino)
            apparent_total_bytes += st.st_size
            total_bytes += st.st_blocks * 512
        for d in dirnames:
            dp = os.path.join(dirpath, d)
            if os.path.islink(dp):
                apparent_total_bytes += os.lstat(dp).st_size
    return (apparent_total_bytes, total_bytes)

Example usage:

>>> du('/lib')
(236425839, 244363264)

$ du -sb /lib
236425839   /lib
$ du -sB1 /lib
244363264   /lib

Human readable file size

Properties of the solution:

• Supports up to Yottabytes
• Supports SI Units or IEC Units
• Support custom suffixes

The code:

def humanized_size(num, suffix='B', si=False):
    if si:
        units = ['','K','M','G','T','P','E','Z']
        last_unit = 'Y'
        div = 1000.0
    else:
        units = ['','Ki','Mi','Gi','Ti','Pi','Ei','Zi']
        last_unit = 'Yi'
        div = 1024.0
    for unit in units:
        if abs(num) < div:
            return "%3.1f%s%s" % (num, unit, suffix)
        num /= div
    return "%.1f%s%s" % (num, last_unit, suffix)

Example usage:

>>> humanized_size(236425839)
'225.5MiB'
>>> humanized_size(236425839, si=True)
'236.4MB'
>>> humanized_size(236425839, si=True, suffix='')
'236.4M'

            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_one, container, false);
        Button buttonSayHi = (Button) view.findViewById(R.id.buttonSayHi);
        buttonSayHi.setOnClickListener(this);
        return view;
    }

But I think is better handle the buttons in this way:

@Override
    public void onClick(View v) {
        switch(v.getId()){
            case R.id.buttonSayHi:
            /** Do things you need to..
               fragmentTwo = new FragmentTwo();

               fragmentTransaction.replace(R.id.frameLayoutFragmentContainer, fragmentTwo);
               fragmentTransaction.addToBackStack(null);

               fragmentTransaction.commit();  
            */
            break;
        }   
    }

As Filburt says; but also note that it's usually better to write

test="not(Count = 'N/A')"

If there's exactly one Count element they mean the same thing, but if there's no Count, or if there are several, then the meanings are different.

Since this answer seems to have become popular, but may be a little cryptic to some readers, let me expand it.

The "=" and "!=" operator in XPath can compare two sets of values. In general, if A and B are sets of values, then "=" returns true if there is any pair of values from A and B that are equal, while "!=" returns true if there is any pair that are unequal.

In the common case where A selects zero-or-one nodes, and B is a constant (say "NA"), this means that not(A = "NA") returns true if A is either absent, or has a value not equal to "NA". By contrast, A != "NA" returns true if A is present and not equal to "NA". Usually you want the "absent" case to be treated as "not equal", which means that not(A = "NA") is the appropriate formulation.

In dealing with databases (in particular MySQL, but this applies to most databases), I found it hard to store UTC.

• Databases usually work with server datetime by default (that is, CURRENT_TIMESTAMP).
• You may not be able to change the server timezone.
• Even if you are able to change the timezone, you may have third-party code that expects server timezone to be local.

I found it easier to just store server datetime in the database, then let the database convert the stored datetime back to UTC (that is, UNIX_TIMESTAMP()) in the SQL statements. After that you can use the datetime as UTC in your code.

If you have 100% control over the server and all code, it's probably better to change server timezone to UTC.

jsonObj.profile-id is a subtraction expression (i.e. jsonObj.profile - id).

To access a key that contains characters that cannot appear in an identifier, use brackets:

jsonObj["profile-id"]

To add to Glenn's great answer, here's what I did to find which files were faulty:

find . -name "*.png" -type f -print0 | xargs \
       -0 pngcrush_1_8_8_w64.exe -n -q > pngError.txt 2>&1

I used the find and xargs because pngcrush could not handle lots of arguments (which were returned by **/*.png). The -print0 and -0 is required to handle file names containing spaces.

Then search in the output for these lines: iCCP: Not recognizing known sRGB profile that has been edited.

./Installer/Images/installer_background.png:    
Total length of data found in critical chunks            =     11286  
pngcrush: iCCP: Not recognizing known sRGB profile that has been edited

And for each of those, run mogrify on it to fix them.

mogrify ./Installer/Images/installer_background.png

Doing this prevents having a commit changing every single png file in the repository when only a few have actually been modified. Plus it has the advantage to show exactly which files were faulty.

I tested this on Windows with a Cygwin console and a zsh shell. Thanks again to Glenn who put most of the above, I'm just adding an answer as it's usually easier to find than comments :)

'a' in x

and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries

If you want to convert an Instant to a Date:

Date myDate = Date.from(instant);

And then you can use SimpleDateFormat for the formatting part of your question:

SimpleDateFormat formatter = new SimpleDateFormat("dd MM yyyy HH:mm:ss");
String formattedDate = formatter.format(myDate);

You can get a pretty coarse idea of the OS you're using by checking sys.platform.

Once you have that information you can use it to determine if calling something like os.uname() is appropriate to gather more specific information. You could also use something like Python System Information on unix-like OSes, or pywin32 for Windows.

There's also psutil if you want to do more in-depth inspection without wanting to care about the OS.

This is how you can achieve this.

upstream {
    nodeapp 127.0.0.1:8080;
}

server {
    listen 80;

    # The host name to respond to
    server_name cdn.domain.com;

    location /(.*) {
        proxy_pass http://nodeapp/$1$is_args$args;
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Real-Port $server_port;
        proxy_set_header X-Real-Scheme $scheme;
    }
}

You can also use this configuration to load balance amongst multiple Node processes like so:

upstream {
    nodeapp 127.0.0.1:8081;
    nodeapp 127.0.0.1:8082;
    nodeapp 127.0.0.1:8083;
}

Where you are running your node server on ports 8081, 8082 and 8083 in separate processes. Nginx will easily load balance your traffic amongst these server processes.

In Visual Studio for Mac and C# you can use:

Environment.SetEnvironmentVariable("<Variable_name>", "<Value>");

But you will need the following namespace

using System.Collections;

you can check the full list of variables with this:

foreach (DictionaryEntry de in Environment.GetEnvironmentVariables())
            Console.WriteLine("  {0} = {1}", de.Key, de.Value);

The most straight forward solution to determine the rank of a given value is to count the number of values before it. Suppose we have the following values:

10 20 30 30 30 40

• All 30 values are considered 3rd
• All 40 values are considered 6th (rank) or 4th (dense rank)

Now back to the original question. Here is some sample data which is sorted as described in OP (expected ranks are added on the right):

+------+-----------+------+--------+    +------+------------+
| id   | firstname | age  | gender |    | rank | dense_rank |
+------+-----------+------+--------+    +------+------------+
|   11 | Emily     |   20 | F      |    |    1 |          1 |
|    3 | Grace     |   25 | F      |    |    2 |          2 |
|   20 | Jill      |   25 | F      |    |    2 |          2 |
|   10 | Megan     |   26 | F      |    |    4 |          3 |
|    8 | Lucy      |   27 | F      |    |    5 |          4 |
|    6 | Sarah     |   30 | F      |    |    6 |          5 |
|    9 | Zoe       |   30 | F      |    |    6 |          5 |
|   14 | Kate      |   35 | F      |    |    8 |          6 |
|    4 | Harry     |   20 | M      |    |    1 |          1 |
|   12 | Peter     |   20 | M      |    |    1 |          1 |
|   13 | John      |   21 | M      |    |    3 |          2 |
|   16 | Cole      |   25 | M      |    |    4 |          3 |
|   17 | Dennis    |   27 | M      |    |    5 |          4 |
|    5 | Scott     |   30 | M      |    |    6 |          5 |
|    7 | Tony      |   30 | M      |    |    6 |          5 |
|    2 | Matt      |   31 | M      |    |    8 |          6 |
|   15 | James     |   32 | M      |    |    9 |          7 |
|    1 | Adams     |   33 | M      |    |   10 |          8 |
|   18 | Smith     |   35 | M      |    |   11 |          9 |
|   19 | Zack      |   35 | M      |    |   11 |          9 |
+------+-----------+------+--------+    +------+------------+

To calculate RANK() OVER (PARTITION BY Gender ORDER BY Age) for Sarah, you can use this query:

SELECT COUNT(id) + 1 AS rank, COUNT(DISTINCT age) + 1 AS dense_rank
FROM testdata
WHERE gender = (SELECT gender FROM testdata WHERE id = 6)
AND age < (SELECT age FROM testdata WHERE id = 6)

+------+------------+
| rank | dense_rank |
+------+------------+
|    6 |          5 |
+------+------------+

To calculate RANK() OVER (PARTITION BY Gender ORDER BY Age) for All rows you can use this query:

SELECT testdata.id, COUNT(lesser.id) + 1 AS rank, COUNT(DISTINCT lesser.age) + 1 AS dense_rank
FROM testdata
LEFT JOIN testdata AS lesser ON lesser.age < testdata.age AND lesser.gender = testdata.gender
GROUP BY testdata.id

And here is the result (joined values are added on right):

+------+------+------------+    +-----------+-----+--------+
| id   | rank | dense_rank |    | firstname | age | gender |
+------+------+------------+    +-----------+-----+--------+

This should accomplish what you want to do. I just tested it on a sheet of mine; let me know if this doesn't work. LTrim is if you only have leading spaces; the Trim function can be used as well as it takes care of leading and trailing spaces. Replace the range of cells in the area I have as "A1:C50" and also make sure to change "Sheet1" to the name of the sheet you're working on.

Dim cell As Range, areaToTrim As Range
Set areaToTrim = Sheet1.Range("A1:C50")
For Each cell In areaToTrim
    cell.Value = LTrim(cell.Value)
Next cell

shiv / shim / sham

If your image(s) are already loaded (or not), this "tool" may come in handy:

Object.defineProperty
(
    HTMLImageElement.prototype,'toDataURL',
    {enumerable:false,configurable:false,writable:false,value:function(m,q)
    {
        let c=document.createElement('canvas');
        c.width=this.naturalWidth; c.height=this.naturalHeight;
        c.getContext('2d').drawImage(this,0,0); return c.toDataURL(m,q);
    }}
);

.. but why?

This has the advantage of using the "already loaded" image data, so no extra request in needed. Aditionally it lets the end-user (programmer like you) decide the CORS and/or mime-type and quality -OR- you can leave out these arguments/parameters as described in the MDN specification here.

If you have this JS loaded (prior to when it's needed), then converting to dataURL is as simple as:

examples

<img src="/yo.jpg" onload="console.log(this.toDataURL('image/jpeg'))">

console.log(document.getElementById("someImgID").toDataURL());

GPU fingerprinting

If you are concerned about the "preciseness" of the bits then you can alter this tool to suit your needs as provided by @Kaiido's answer.

This should be faster.

while ($personCount < 10) {
    $result .= "{$personCount} people ";
    $personCount++;
}

echo $result;

Citation from here:

This is actually by design. There seems to be no good reason to inherit a static class. It has public static members that you can always access via the class name itself. The only reasons I have seen for inheriting static stuff have been bad ones, such as saving a couple of characters of typing.

There may be reason to consider mechanisms to bring static members directly into scope (and we will in fact consider this after the Orcas product cycle), but static class inheritance is not the way to go: It is the wrong mechanism to use, and works only for static members that happen to reside in a static class.

(Mads Torgersen, C# Language PM)

Other opinions from channel9

Inheritance in .NET works only on instance base. Static methods are defined on the type level not on the instance level. That is why overriding doesn't work with static methods/properties/events...

Static methods are only held once in memory. There is no virtual table etc. that is created for them.

If you invoke an instance method in .NET, you always give it the current instance. This is hidden by the .NET runtime, but it happens. Each instance method has as first argument a pointer (reference) to the object that the method is run on. This doesn't happen with static methods (as they are defined on type level). How should the compiler decide to select the method to invoke?

And as a valuable idea, littleguru has a partial "workaround" for this issue: the Singleton pattern.

I think ResponseEntityExceptionHandler meets your requirements. A sample piece of code for HTTP 400:

@ControllerAdvice
public class MyExceptionHandler extends ResponseEntityExceptionHandler {

  @ResponseStatus(value = HttpStatus.BAD_REQUEST)
  @ExceptionHandler({HttpMessageNotReadableException.class, MethodArgumentNotValidException.class,
      HttpRequestMethodNotSupportedException.class})
  public ResponseEntity<Object> badRequest(HttpServletRequest req, Exception exception) {
    // ...
  }
}

You can check this post

git log --format="%h" | tail -1 gives you the commit hash (ie 0dd89fb), which you can feed into other commands, by doing something like

git diff `git log --format="%h" --after="1 day"| tail -1`..HEAD to view all the commits in the last day.

Just had this issue with an Outlook client going through a Exchange server to an external address on Windows XP. Clearing the temp files seemed to do the trick.

I can actually think of two ways to do it:

1. slice the list like (this deletes the 1st,3rd and 8th elements)

   somelist = somelist[1:2]+somelist[3:7]+somelist[8:]

2. do that in place, but one at a time:

   somelist.pop(2) somelist.pop(0)

Strings do have a length method: __len__()

The protocol in Python is to implement this method on objects which have a length and use the built-in len() function, which calls it for you, similar to the way you would implement __iter__() and use the built-in iter() function (or have the method called behind the scenes for you) on objects which are iterable.

See Emulating container types for more information.

Here's a good read on the subject of protocols in Python: Python and the Principle of Least Astonishment

The following was tested for IIS 8.5 and Windows 8.1.

As of IIS 7, Windows recommends restarting IIS via net stop/start. Via the command prompt (as Administrator):

> net stop WAS
> net start W3SVC

net stop WAS will stop W3SVC as well. Then when starting, net start W3SVC will start WAS as a dependency.

If they're using basic authentication:

wget http://username:[email protected]/page.html

If they're using POSTed form data, you'll need to use something like cURL instead.

If you are using Android Lollipop i.e. SDK 21, then:

CookieManager.getInstance().setAcceptCookie(true);

won't work. You need to use:

CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);

I ran into same issue and the above line worked as a charm.

In workbench 6.0 Connect to any of the database. You will see two tabs.

1.Management 2. Schemas

By default Schemas tab is selected. Select Management tab then select Data Export . You will get list of all databases. select the desired database and and the file name and ther options you wish and start export. You are done with backup.

I use:

var value = "'Field1','Field2','Field3'".Replace("'", "\""); 

as opposed to the equivalent

var value = "\"Field1\",\"Field2\",\"Field3\"";

Because the former has far less noise than the latter, making it easier to see typo's etc.

I use it a lot in unit tests.

// get checkbox values using checkbox's name

<head>
        <script>
        function getCheckBoxValues(){
            $('[name="checkname"]').each( function (){
                alert($(this).val());
            });
        }
        </script>
    </head>
    <body>
        <input type="checkbox" name="checkname" value='1'/>
        <input type="checkbox" name="checkname" value='2'/>
        <input type="checkbox" name="checkname" value='3'/>
        <input type="button" value="CheckBoxValues" onclick="getCheckBoxValues()"/>
    </body>

// get only the values witch are checked

function getCheckBoxValues(){
        $('[name="checkname"]').each( function (){
            if($(this).prop('checked') == true){
                alert($(this).val());
            }

To remove a record.

 var db = firebase.database();                   
 var ref = db.ref(); 
 var survey=db.ref(path+'/'+path);    //Eg path is company/employee                
 survey.child(key).remove();          //Eg key is employee id

Here is a query, you can run it in SQL Developer (or SQL*Plus):

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
  FROM DBA_SEGMENTS DS
  WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES)
 GROUP BY DS.TABLESPACE_NAME,
       SEGMENT_NAME;

These both work fine for me...

<?php
  $db = mysql_connect('localhost','user','pass');
  mysql_select_db('test_db');

  $stmt = "INSERT INTO `test` (`first`,`last`,`whenadded`) VALUES ".
          "('{$first}','{$last}','NOW())";
  $rslt = mysql_query($stmt);

  $stmt = "INSERT INTO `users` (`first`,`last`,`whenadded`) VALUES ".
          "('{$first}', '{$last}', CURRENT_TIMESTAMP)";
  $rslt = mysql_query($stmt);

?>

Side note: mysql_query() is not the best way to connect to MySQL in current versions of PHP.

You could create Util class:

public final class CollectionHelpers {
    public static <T> boolean addNullSafe(List<T> list, T element) {
        if (list == null || element == null) {
            return false;
        }

        return list.add(element);
    }
}

And then use it:

Element element = getElementFromSomeWhere(someParameter);
List<Element> arrayList = new ArrayList<>();
CollectionHelpers.addNullSafe(list, element);

If you happen to process the value with some string function before saving, make sure the function can properly handle multibyte characters. String functions that cannot do that and are, say, attempting to truncate might split one of the single multibyte characters in the middle, and that can cause such string error situations.

In PHP for instance, you would need to switch from substr to mb_substr.

First, you can switch on an enum in Java. I'm guessing you intended to say you can’t, but you can. chars have a set range of values, so it's easy to compare. Strings can be anything.

A switch statement is usually implemented as a jump table (branch table) in the underlying compilation, which is only possible with a finite set of values. C# can switch on strings, but it causes a performance decrease because a jump table cannot be used.

Java 7 and later supports String switches with the same characteristics.

For windows specifically: \path\to\python.exe -m pip install PackageName works.

You can quickly serve static content in JAVA Spring-boot App via thymeleaf (ref: source)

I assume you have already added Spring Boot plugin apply plugin: 'org.springframework.boot' and the necessary buildscript

Then go ahead and ADD thymeleaf to your build.gradle ==>

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

Lets assume you have added home.html at src/main/resources To serve this file, you will need to create a controller.

package com.ajinkya.th.controller;

  import org.springframework.stereotype.Controller;
  import org.springframework.web.bind.annotation.RequestMapping;

  @Controller
  public class HomePageController {

      @RequestMapping("/")
      public String homePage() {
        return "home";
      }

  }

Thats it ! Now restart your gradle server. ./gradlew bootRun

        var hours = currentTime.getHours()
        //Note: before converting into 12 hour format
        var suffix = '';
        if (hours > 11) {
            suffix += "PM";
        } else {
            suffix += "AM";
        }
        var minutes = currentTime.getMinutes()
        if (minutes < 10) {
            minutes = "0" + minutes
        }
        if (hours > 12) {
            hours -= 12;
        } else if (hours === 0) {
            hours = 12;
        }
        var time = hours + ":" + minutes + " " + suffix;
        return time;
    }

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).

tolist() works fine even if encountered a nested array, say a pandas DataFrame;

my_list = [0,1,2,3,4,5,4,3,2,1,0]
my_dt = pd.DataFrame(my_list)
new_list = [i[0] for i in my_dt.values.tolist()]

print(type(my_list),type(my_dt),type(new_list))

If you are using Git Gui on windows,

1. Abort the merge
2. Make sure you are on your target branch
3. Delete the conflicting file from explorer
4. Rescan for changes in Git Gui (F5)
5. Notice that conflicting file is deleted
6. Select Stage Changed Files To Commit (Ctrl-I) from Commit menu
7. Enter a commit comment like "deleted conflicting file"
8. Commit (ctrl-enter)
9. Now if you restart the merge it will (hopefully) work.

Not really - the only thing you could realistically do is offer advice on the site; maybe, before their first time signing in, you could show them a form with information indicating that it is not recommended that they allow the browser to store the password.

Then the user will immediately follow the advice, write down the password on a post-it note and tape it to their monitor.

below code can be put inside a main method

    // TODO Auto-generated method stub
    Integer[] a = { 11, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 3, 4, 1, 2, 2, 2, 2, 3, 4, 2 };
    List<Integer> list = new ArrayList<Integer>(Arrays.asList(a));
    Set<Integer> set = new HashSet<Integer>(list);
    int highestSeq = 0;
    int seq = 0;
    for (int i : set) {
        int tempCount = 0;
        for (int l : list) {
            if (i == l) {
                tempCount = tempCount + 1;
            }
            if (tempCount > highestSeq) {
                highestSeq = tempCount;
                seq = i;
            }
        }

    }

    System.out.println("highest sequence is " + seq + " repeated for " + highestSeq);

Setting autoScroll to true did not the trick for me, so I did choose another solution. I built a service that hooks in every time the route changes and that uses the built-in $anchorScroll service to scroll to top. Works for me :-).

Service:

 (function() {
    "use strict";

    angular
        .module("mymodule")
        .factory("pageSwitch", pageSwitch);

    pageSwitch.$inject = ["$rootScope", "$anchorScroll"];

    function pageSwitch($rootScope, $anchorScroll) {
        var registerListener = _.once(function() {
            $rootScope.$on("$locationChangeSuccess", scrollToTop);
        });

        return {
            registerListener: registerListener
        };

        function scrollToTop() {
            $anchorScroll();
        }
    }
}());

Registration:

angular.module("mymodule").run(["pageSwitch", function (pageSwitch) {
    pageSwitch.registerListener();
}]);

You have to reimplement it using <xsl:choose> tag:

       <xsl:choose>
         <xsl:when test="$CreatedDate > $IDAppendedDate">
           <h2> mooooooooooooo </h2>
         </xsl:when>
         <xsl:otherwise>
          <h2> dooooooooooooo </h2>
         </xsl:otherwise>
       </xsl:choose>
