Programs & Examples On #Graphic effects

I had an issue when setting react state multiple times (it always used default state). Following this react/github issue worked for me

const [state, setState] = useState({
  foo: "abc",
  bar: 123
});

// Do this!
setState(prevState => {
  return {
    ...prevState,
    foo: "def"
  };
});
setState(prevState => {
  return {
    ...prevState,
    bar: 456
  };
});

There are no sleep() functions in the pre-C11 C Standard Library, but POSIX does provide a few options.

The POSIX function sleep() (unistd.h) takes an unsigned int argument for the number of seconds desired to sleep. Although this is not a Standard Library function, it is widely available, and glibc appears to support it even when compiling with stricter settings like --std=c11.

The POSIX function nanosleep() (time.h) takes two pointers to timespec structures as arguments, and provides finer control over the sleep duration. The first argument specifies the delay duration. If the second argument is not a null pointer, it holds the time remaining if the call is interrupted by a signal handler.

Programs that use the nanosleep() function may need to include a feature test macro in order to compile. The following code sample will not compile on my linux system without a feature test macro when I use a typical compiler invocation of gcc -std=c11 -Wall -Wextra -Wpedantic.

POSIX once had a usleep() function (unistd.h) that took a useconds_t argument to specify sleep duration in microseconds. This function also required a feature test macro when used with strict compiler settings. Alas, usleep() was made obsolete with POSIX.1-2001 and should no longer be used. It is recommended that nanosleep() be used now instead of usleep().

#define _POSIX_C_SOURCE  199309L     // feature test macro for nanosleep()

#include <stdio.h>
#include <unistd.h>    // for sleep()
#include <time.h>      // for nanosleep()

int main(void)
{
    // use unsigned sleep(unsigned seconds)
    puts("Wait 5 sec...");
    sleep(5);

    // use int nanosleep(const struct timespec *req, struct timespec *rem);
    puts("Wait 2.5 sec...");
    struct timespec ts = { .tv_sec = 2,          // seconds to wait
                           .tv_nsec = 5e8 };     // additional nanoseconds
    nanosleep(&ts, NULL);
    puts("Bye");

    return 0;
}

Addendum:

C11 does have the header threads.h providing thrd_sleep(), which works identically to nanosleep(). GCC did not support threads.h until 2018, with the release of glibc 2.28. It has been difficult in general to find implementations with support for threads.h (Clang did not support it for a long time, but I'm not sure about the current state of affairs there). You will have to use this option with care.

Try this:

from __future__ import with_statement

filename1 = "G:\\test1.TXT"
filename2 = "G:\\test2.TXT"


with open(filename1) as f1:
   with open(filename2) as f2:
      file1list = f1.read().splitlines()
      file2list = f2.read().splitlines()
      list1length = len(file1list)
      list2length = len(file2list)
      if list1length == list2length:
          for index in range(len(file1list)):
              if file1list[index] == file2list[index]:
                  print file1list[index] + "==" + file2list[index]
              else:                  
                  print file1list[index] + "!=" + file2list[index]+" Not-Equel"
      else:
          print "difference inthe size of the file and number of lines"

That depends on what you mean by delete. An array has a fixed size, so deleting doesn't really make sense.

If you want to remove element i, one option would be to move all elements j > i one position to the left (a[j - 1] = a[j] for all j, or using Array.Copy) and then resize the array using ReDim Preserve.

So, unless you are forced to use an array by some external constraint, consider using a data structure more suitable for adding and removing items. List<T>, for example, also uses an array internally but takes care of all the resizing issues itself: For removing items, it uses the algorithm mentioned above (without the ReDim), which is why List<T>.RemoveAt is an O(n) operation.

There's a whole lot of different collection classes in the System.Collections.Generic namespace, optimized for different use cases. If removing items frequently is a requirement, there are lots of better options than an array (or even List<T>).

1. rebuild project in VS
2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

Backout restores or undoes our changes. The way it does this is that, P4 undoes the changes in a changelist (default or new) on our local workspace. We then have to submit/commit this backedout changelist as we do other changeslists. The second part is important here, as it doesn't automatically backout the changelist on the server, we have to submit the backedout changelist (which makes sense after you do it, but i was initially assuming it does that automatically).

As pointed by others, Rollback has greater powers - It can restore changes to a specific date, changelist or a revision#

Use a smarty template for your stuff then just set the POST array as a smarty array and open the template. In the template just echo out the array so if it passes:

if(correct){
    header("Location: passed.php");
} else {
    $smarty->assign("variables", $_POST);
    $smarty->display("register_error.php");
    exit;
}

I have not tried this yet but I am going to try it as a solution and will let you know what I find. But of course this method assumes that you are using smarty.

If not you can just recreate your form there on the error page and echo info into the form or you could send back non important data in a get from and get it

ex.

register.php?name=mr_jones&address==......
echo $_GET[name];

It is very simple to make a variable global in a class:

a = 0

class b():
    global a
    a = 10

>>> a
10

Try this:

lst = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")]
print([s.strip('8') for s in lst]) # remove the 8 from the string borders
print([s.replace('8', '') for s in lst]) # remove all the 8s 

I experienced this today. The value in Config was the updated one but the application would return the older value, stop and starting the solution did nothing.

So I cleared the .Net Temp folder.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

It shouldn't create bugs but to be safe close your solution down first. Clear the Temporary ASP.NET Files then load up your solution.

My issue was sorted.

You can do like this in more natural way,

case expression
when condtion1
   function
when condition2
   function
else
   function
end

Joe Kington's excellent answer is already 4 years old, Matplotlib has incrementally changed (in particular, the introduction of the cycler module) and the new major release, Matplotlib 2.0.x, has introduced stylistic differences that are important from the point of view of the colors used by default.

The color of individual lines

The color of individual lines (as well as the color of different plot elements, e.g., markers in scatter plots) is controlled by the color keyword argument,

plt.plot(x, y, color=my_color)

my_color is either

• a tuple of floats representing RGB or RGBA (as(0.,0.5,0.5)),
• a RGB/RGBA hex string (as "#008080" (RGB) or "#008080A0"),
• a string representation of a float value in [0, 1] inclusive for gray level (e.g., '0.6'),
• a short color name (as "k" for black, possible values in "bgrcmykw"),
• a long color name (as "teal") --- aka HTML color name (in the docs also X11/CSS4 color name),
• a name from the xkcd color survey, prefixed with 'xkcd:' (e.g., 'xkcd:barbie pink'),
• a color from the Tableau Colors in the default 'T10' categorical palette, (e.g., 'tab:blue', 'tab:olive'),
• a reference to a color of the current color cycle (as "C3", i.e., the letter "C" followed by a single digit in "0-9").

The color cycle

By default, different lines are plotted using different colors, that are defined by default and are used in a cyclic manner (hence the name color cycle).

The color cycle is a property of the axes object, and in older releases was simply a sequence of valid color names (by default a string of one character color names, "bgrcmyk") and you could set it as in

my_ax.set_color_cycle(['kbkykrkg'])

(as noted in a comment this API has been deprecated, more on this later).

In Matplotlib 2.0 the default color cycle is ["#1f77b4", "#ff7f0e", "#2ca02c", "#d62728", "#9467bd", "#8c564b", "#e377c2", "#7f7f7f", "#bcbd22", "#17becf"], the Vega category10 palette.

_{(the image is a screenshot from https://vega.github.io/vega/docs/schemes/)}

The cycler module: composable cycles

The following code shows that the color cycle notion has been deprecated

In [1]: from matplotlib import rc_params

In [2]: rc_params()['axes.color_cycle']
/home/boffi/lib/miniconda3/lib/python3.6/site-packages/matplotlib/__init__.py:938: UserWarning: axes.color_cycle is deprecated and replaced with axes.prop_cycle; please use the latter.
  warnings.warn(self.msg_depr % (key, alt_key))
Out[2]: 
['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd',
 '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf']

Now the relevant property is the 'axes.prop_cycle'

In [3]: rc_params()['axes.prop_cycle']
Out[3]: cycler('color', ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf'])

Previously, the color_cycle was a generic sequence of valid color denominations, now by default it is a cycler object containing a label ('color') and a sequence of valid color denominations. The step forward with respect to the previous interface is that it is possible to cycle not only on the color of lines but also on other line attributes, e.g.,

In [5]: from cycler import cycler

In [6]: new_prop_cycle = cycler('color', ['k', 'r']) * cycler('linewidth', [1., 1.5, 2.])

In [7]: for kwargs in new_prop_cycle: print(kwargs)
{'color': 'k', 'linewidth': 1.0}
{'color': 'k', 'linewidth': 1.5}
{'color': 'k', 'linewidth': 2.0}
{'color': 'r', 'linewidth': 1.0}
{'color': 'r', 'linewidth': 1.5}
{'color': 'r', 'linewidth': 2.0}

As you have seen, the cycler objects are composable and when you iterate on a composed cycler what you get, at each iteration, is a dictionary of keyword arguments for plt.plot.

You can use the new defaults on a per axes object ratio,

my_ax.set_prop_cycle(new_prop_cycle)

or you can install temporarily the new default

plt.rc('axes', prop_cycle=new_prop_cycle)

or change altogether the default editing your .matplotlibrc file.

Last possibility, use a context manager

with plt.rc_context({'axes.prop_cycle': new_prop_cycle}):
    ...

to have the new cycler used in a group of different plots, reverting to defaults at the end of the context.

The doc string of the cycler() function is useful, but the (not so much) gory details about the cycler module and the cycler() function, as well as examples, can be found in the fine docs.

Found this elsewhere here but this is a simple solution that works:

 WITH cte AS /* Declaring a new table named 'cte' to be a clone of your table */
 (SELECT *, ROW_NUMBER() OVER (PARTITION BY id ORDER BY val1 DESC) AS rn
 FROM MyTable /* Selecting only unique values based on the "id" field */
 )
 SELECT * /* Here you can specify several columns to retrieve */
 FROM cte
 WHERE rn = 1

You want:

DECLARE @times int

SELECT @times =  COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

You also don't need the 'as' clause.

The following example creates a file chooser and displays it as first an open-file dialog and then as a save-file dialog:

String filename = File.separator+"tmp";
JFileChooser fc = new JFileChooser(new File(filename));

// Show open dialog; this method does not return until the dialog is closed
fc.showOpenDialog(frame);
File selFile = fc.getSelectedFile();

// Show save dialog; this method does not return until the dialog is closed
fc.showSaveDialog(frame);
selFile = fc.getSelectedFile();

Here is a more elaborate example that creates two buttons that create and show file chooser dialogs.

// This action creates and shows a modal open-file dialog.
public class OpenFileAction extends AbstractAction {
    JFrame frame;
    JFileChooser chooser;

    OpenFileAction(JFrame frame, JFileChooser chooser) {
        super("Open...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showOpenDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

// This action creates and shows a modal save-file dialog.
public class SaveFileAction extends AbstractAction {
    JFileChooser chooser;
    JFrame frame;

    SaveFileAction(JFrame frame, JFileChooser chooser) {
        super("Save As...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showSaveDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

Warning suppression is not a solution. You should not be doing two level casting in one statement.

HashMap<String, String> getItems(javax.servlet.http.HttpSession session) {

    // first, cast the returned Object to generic HashMap<?,?>
    HashMap<?, ?> theHash = (HashMap<?, ?>)session.getAttribute("attributeKey");

    // next, cast every entry of the HashMap to the required type <String, String>
    HashMap<String, String> returingHash = new HashMap<>();
    for (Entry<?, ?> entry : theHash.entrySet()) {
        returingHash.put((String) entry.getKey(), (String) entry.getValue());
    }
    return returingHash;
}

Your code works for me

$date = '15-12-2016';
$nameOfDay = date('D', strtotime($date));
echo $nameOfDay;

Use l instead of D, if you prefer the full textual representation of the name

I too got the same error and was able to resolve the error by adding the below dependency to my pom.xml.

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>

Reason is we are using JSP as the view. Default embedded servlet container for Spring Boot Starter Web is tomcat. To enable support for JSP’s, we would need to add a dependency on tomcat-embed-jasper.

In my case I was returning a JSP as view from controller. Hope this answer helps someone who are struggling with same issue.

Adding a quick snippet to have it ready to execute:

Source: myparser.py

import argparse
parser = argparse.ArgumentParser(description="Flip a switch by setting a flag")
parser.add_argument('-w', action='store_true')

args = parser.parse_args()
print args.w

Usage:

python myparser.py -w
>> True

Use Like this:

Uri uri = Uri.parse(URL); //Declare your url here.

VideoView mVideoView  = (VideoView)findViewById(R.id.videoview)
mVideoView.setMediaController(new MediaController(this));       
mVideoView.setVideoURI(uri);
mVideoView.requestFocus();
mVideoView.start();

Another Method:

  String LINK = "type_here_the_link";
  VideoView mVideoView  = (VideoView) findViewById(R.id.videoview);
  MediaController mc = new MediaController(this);
  mc.setAnchorView(videoView);
  mc.setMediaPlayer(videoView);
  Uri video = Uri.parse(LINK);
  mVideoView.setMediaController(mc);
  mVideoView.setVideoURI(video);
  mVideoView.start();

If you are getting this error Couldn't open file on client side, trying server side Error in Android. and also Refer this. Hope this will give you some solution.

Here is how I do it on iOS 9 in Swift -

import UIKit

class CustomView : UIView {

    init() {
        super.init(frame: UIScreen.mainScreen().bounds);

        //for debug validation
        self.backgroundColor = UIColor.blueColor();
        print("My Custom Init");

        return;
    }

    required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented"); }
}

Here is a full project with example:

• UIView Example Project (with SubView example)

#if DEBUG
    System.Diagnostics.Debugger.Break();
#endif

So another way, which I prefer, is to just split the values, for example:

#/path/to/config.cfg
[Numbers]
first_row = 1,2,4,8,12,24,36,48

Could be loaded like this into a list of strings or integers, as follows:

import configparser

config = configparser.ConfigParser()
config.read('/path/to/config.cfg')

# Load into a list of strings
first_row_strings = config.get('Numbers', 'first_row').split(',')

# Load into a list of integers
first_row_integers = [int(x) for x in config.get('Numbers', 'first_row').split(',')]

This method prevents you from needing to wrap your values in brackets to load as JSON.

Why make it so complicated? This worked.

SELECT m_id,v_id,MAX(TIMESTAMP) AS TIME
 FROM table_name 
 GROUP BY m_id

 select p.post_title,m.meta_value sale_price ,n.meta_value   regular_price
    from  wp_postmeta m 
    inner join wp_postmeta n
      on m.post_id  = n.post_id
    inner join wp_posts p
      ON m.post_id=p.id 
    and m.meta_key = '_sale_price'
    and  n.meta_key = '_regular_price'
     AND p.post_type = 'product';



 update  wp_postmeta m 
inner join wp_postmeta n
  on m.post_id  = n.post_id
inner join wp_posts p
  ON m.post_id=p.id 
and m.meta_key = '_sale_price'
and  n.meta_key = '_regular_price'
 AND p.post_type = 'product'
 set m.meta_value = n.meta_value;

In a Firebird database the AFTER myOtherColumn does not work but you can try re-positioning the column using:

ALTER TABLE name ALTER column POSITION new_position

I guess it may work in other cases as well.

Simply add alignSelf: "stretch" to your item's stylesheet.

line1: {
    backgroundColor: '#FDD7E4',
    alignSelf: 'stretch',
    textAlign: 'center',
},

You can still use filter, moving to an outside function the element modification (iterating just once)

def do_the_magic(x):
    do_action(x)
    return check(x)

# you can get a different filtered list
filter(do_the_magic,yourList)

# or have it modified in place (as suggested by Steven Rumbalski, see comment)
yourList[:] = itertools.ifilter(do_the_magic, yourList)

It is possible in Python 3 since v3.1 and Python 2.7. The new with syntax supports multiple context managers:

with A() as a, B() as b, C() as c:
    doSomething(a,b,c)

Unlike the contextlib.nested, this guarantees that a and b will have their __exit__()'s called even if C() or it's __enter__() method raises an exception.

You can also use earlier variables in later definitions (h/t Ahmad below):

with A() as a, B(a) as b, C(a, b) as c:
    doSomething(a, c)

For just plotting a vector, you should use the following command:

text(your.vector, labels=your.labels, cex= labels.size, pos=labels.position)

A PHP Based Solution for search entire table ! Search string is $string . This is generic and will work with all the tables with any number of fields

$sql="SELECT * from client_wireless";
$sql_query=mysql_query($sql);
$logicStr="WHERE ";
$count=mysql_num_fields($sql_query);
for($i=0 ; $i < mysql_num_fields($sql_query) ; $i++){
 if($i == ($count-1) )
$logicStr=$logicStr."".mysql_field_name($sql_query,$i)." LIKE '%".$string."%' ";
else
$logicStr=$logicStr."".mysql_field_name($sql_query,$i)." LIKE '%".$string."%' OR ";
}
// start the search in all the fields and when a match is found, go on printing it .
$sql="SELECT * from client_wireless ".$logicStr;
//echo $sql;
$query=mysql_query($sql);

    <link rel="shortcut icon" href="@Url.Content("~/images/")favicon.ico" type="image/x-icon"/ >

This works for me in MVC4 application favicon image is placed in the images folder and it will traverse from root directory to images and find favicon.ico bingo!

You can use UIGraphicsBeginImageContext method to set the size of image same that of view.

Syntax : void UIGraphicsBeginImageContext(CGSize size);

 #define IMAGE(imageName) (UIImage *)[UIImage imageWithContentsOfFile:
  [[NSBundle mainBundle] pathForResource:imageName ofType:IMAGE_TYPE_PNG]]

        UIGraphicsBeginImageContext(self.view.frame.size);
        [[UIImage imageNamed:@“MyImage.png"] drawInRect:self.view.bounds];
        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    self.view.backgroundColor = [UIColor colorWithPatternImage:IMAGE(@"mainBg")];

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

static variables are stored in the heap

Just a reminder. Beware for double.

Math.Round(0.3 / 0.2 ) result in 1, because in double 0.3 / 0.2 = 1.49999999
Math.Round( 1.5 ) = 2

I also enable the 'u' option on every bash script I write in order to do some extra checking:

set -u 

This will report the usage of uninitialized variables, like in the following script 'check_init.sh'

#!/bin/sh
set -u
message=hello
echo $mesage

Running the script :

$ check_init.sh

Will report the following :

./check_init.sh[4]: mesage: Parameter not set.

Very useful to catch typos

You're so close!

The error arises because gnuplot is trying to interpret the word "plot" as the filename to plot, but you haven't assigned any strings to a variable named "plot" (which is good – that would be super confusing).

look at this: https://developer.mozilla.org/en-US/docs/Web/API/event.keyCode

In a keypress event, the Unicode value of the key pressed is stored in either the keyCode or charCode property, never both. If the key pressed generates a character (e.g. 'a'), charCode is set to the code of that character, respecting the letter case. (i.e. charCode takes into account whether the shift key is held down). Otherwise, the code of the pressed key is stored in keyCode. keyCode is always set in the keydown and keyup events. In these cases, charCode is never set. To get the code of the key regardless of whether it was stored in keyCode or charCode, query the which property. Characters entered through an IME do not register through keyCode or charCode.

If you are using GCC, you can use the GNU extension asprintf function.

char* str;
asprintf (&str, "%i", 12313);
free(str);

From the docs:

To extract the files from a jar file, use x, as in:

C:\Java> jar xf myFile.jar

To extract only certain files from a jar file, supply their filenames:

C:\Java> jar xf myFile.jar foo bar

The folder where jar is probably isn't C:\Java for you, on my Windows partition it's:

C:\Program Files (x86)\Java\jdk[some_version_here]\bin

Unless the location of jar is in your path environment variable, you'll have to specify the full path/run the program from inside the folder.

EDIT: Here's another article, specifically focussed on extracting JARs: http://docs.oracle.com/javase/tutorial/deployment/jar/unpack.html

Forward declaration should have complete template arguments list specified.

There isn’t really an ideal conversion, but I would like to supply a couple of options.

java.time

First, you should use LocalDate from java.time, the modern Java date and time API, for parsing and holding your date. Avoid Date and SimpleDateFormat since they have design problems and also are long outdated. The latter in particular is notoriously troublesome.

    DateTimeFormatter originalDateFormatter = DateTimeFormatter.ofPattern("dd/MM/uuuu");

    String dateString = "13/06/1983";
    LocalDate date = LocalDate.parse(dateString, originalDateFormatter);
    System.out.println(date);

The output is:

1983-06-13

Do you need to go any further? LocalDate.toString() produces the format you asked about.

Format and parse

Assuming that you do require an XMLGregorianCalendar the first and easy option for converting is:

    XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(date.toString());
    System.out.println(xmlDate);

1983-06-13

Formatting to a string and parsing it back feels like a waste to me, but as I said, it’s easy and I don’t think that there are any surprises about the result being as expected.

Pass year, month and day of month individually

    XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
            .newXMLGregorianCalendarDate(date.getYear(), date.getMonthValue(),
                    date.getDayOfMonth(), DatatypeConstants.FIELD_UNDEFINED);

The result is the same as before. We need to make explicit that we don’t want a time zone offset (this is what DatatypeConstants.FIELD_UNDEFINED specifies). In case someone is wondering, both LocalDate and XMLGregorianCalendar number months the way humans do, so there is no adding or subtracting 1.

Convert through GregorianCalendar

I only show you this option because I somehow consider it the official way: convert LocalDate to ZonedDateTime, then to GregorianCalendar and finally to XMLGregorianCalendar.

    ZonedDateTime dateTime = date.atStartOfDay(ZoneOffset.UTC);
    GregorianCalendar gregCal = GregorianCalendar.from(dateTime);
    XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gregCal);
    xmlDate.setTime(DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED,
            DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED);
    xmlDate.setTimezone(DatatypeConstants.FIELD_UNDEFINED);

I like the conversion itself since we neither need to use strings nor need to pass individual fields (with care to do it in the right order). What I don’t like is that we have to pass a time of day and a time zone offset and then wipe out those fields manually afterwards.

I recently used the following in an application that is working well for my needs.

.htaccess

<IfModule mod_rewrite.c>
# enable rewrite engine
RewriteEngine On

# if requested url does not exist pass it as path info to index.php
RewriteRule ^$ index.php?/ [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php?/$1 [QSA,L]
</IfModule>

index.php

foreach (explode ("/", $_SERVER['REQUEST_URI']) as $part)
{
    // Figure out what you want to do with the URL parts.
}

All the answers here are determining if the element is fully contained within the viewport, not just visible in some way. For example, if only half of an image is visible at the bottom of the view, the solutions here will fail, considering that "outside".

I had a use case where I'm doing lazy loading via IntersectionObserver, but due to animations that occur during pop-in, I didn't want to observe any images that were already intersected on page load. To do that, I used the following code:

const bounding = el.getBoundingClientRect();
const isVisible = (0 < bounding.top && bounding.top < (window.innerHeight || document.documentElement.clientHeight)) ||
        (0 < bounding.bottom && bounding.bottom < (window.innerHeight || document.documentElement.clientHeight));

This is basically checking to see if either the top or bottom bound is independently in the viewport. The opposite end may be outside, but as long as one end is in, it's "visible" at least partially.

Use a BindingList and set the DataPropertyName-Property of the column.

Try the following:

...
private void BindGrid()
{
    gvFilesOnServer.AutoGenerateColumns = false;

    //create the column programatically
    DataGridViewCell cell = new DataGridViewTextBoxCell();
    DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn()
    {
        CellTemplate = cell, 
        Name = "Value",
        HeaderText = "File Name",
        DataPropertyName = "Value" // Tell the column which property of FileName it should use
     };

    gvFilesOnServer.Columns.Add(colFileName);

    var filelist = GetFileListOnWebServer().ToList();
    var filenamesList = new BindingList<FileName>(filelist); // <-- BindingList

    //Bind BindingList directly to the DataGrid, no need of BindingSource
    gvFilesOnServer.DataSource = filenamesList 
}

Use th:switch as an if-else

<span th:switch="${isThisTrue}">
  <i th:case="true" class="fas fa-check green-text"></i>
  <i th:case="false" class="fas fa-times red-text"></i>
</span>

Use th:switch as a switch

<span th:switch="${fruit}">
  <i th:case="Apple" class="fas fa-check red-text"></i>
  <i th:case="Orange" class="fas fa-times orange-text"></i>
  <i th:case="*" class="fas fa-times yellow-text"></i>
</span>

Google aparently has a library for this sort of thing: http://code.google.com/p/jlibs/wiki/AnsiColoring

There's also a Javaworld article on this which solves your problem: http://www.javaworld.com/javaworld/javaqa/2002-12/02-qa-1220-console.html

This answer attempts a pragmatic summary of the many great answers on this page:

^{jeb's great answer deserves special mention, because it really goes in-depth and covers many edge cases.
Notably, he points out that a misconstructed variable/parameter reference such as %~ can break any of the solutions below - including REM lines.}

Whole-line comments - the only directly supported style:

• REM (or case variations thereof) is the only official comment construct, and is the safest choice - see Joey's helpful answer.

• :: is a (widely used) hack, which has pros and cons:

  • Pros:

    • Visual distinctiveness and, possibly, ease of typing.
    • Speed, although that will probably rarely matter - see jeb's great answer and Rob van der Woude's excellent blog post.

  • Cons:

    • Inside (...) blocks, :: can break the command, and the rules for safe use are restrictive and not easy to remember - see below.

If you do want to use ::, you have these choices:

• Either: To be safe, make an exception inside (...) blocks and use REM there, or do not place comments inside (...) altogether.
• Or: Memorize the painfully restrictive rules for safe use of :: inside (...), which are summarized in the following snippet:

@echo off

for %%i in ("dummy loop") do (

  :: This works: ONE comment line only, followed by a DIFFERENT, NONBLANK line.
  date /t

  REM If you followed a :: line directly with another one, the *2nd* one
  REM would generate a spurious "The system cannot find the drive specified."
  REM error message and potentially execute commands inside the comment.
  REM In the following - commented-out - example, file "out.txt" would be
  REM created (as an empty file), and the ECHO command would execute.
  REM   :: 1st line
  REM   :: 2nd line > out.txt & echo HERE

  REM NOTE: If :: were used in the 2 cases explained below, the FOR statement
  REM would *break altogether*, reporting:
  REM  1st case: "The syntax of the command is incorrect."
  REM  2nd case: ") was unexpected at this time."

  REM Because the next line is *blank*, :: would NOT work here.

  REM Because this is the *last line* in the block, :: would NOT work here.
)

Emulation of other comment styles - inline and multi-line:

Note that none of these styles are directly supported by the batch language, but can be emulated.

Inline comments:

<sup>* The code snippets below use ver as a stand-in for an arbitrary command, so as to facilitate experimentation.
* To make SET commands work correctly with inline comments, double-quote the name=value part; e.g., SET "foo=bar".[1]</sup>

In this context we can distinguish two subtypes:

• EOL comments ([to-the-]end-of-line), which can be placed after a command, and invariably extend to the end of the line (again, courtesy of jeb's answer):

  • ver & REM <comment> takes advantage of the fact that REM is a valid command and & can be used to place an additional command after an existing one.
  • ver & :: <comment> works too, but is really only usable outside of (...) blocks, because its safe use there is even more limited than using :: standalone.

• Intra-line comments, which be placed between multiple commands on a line or ideally even inside of a given command.
  Intra-line comments are the most flexible (single-line) form and can by definition also be used as EOL comments.

  • ver & REM^. ^<comment^> & ver allows inserting a comment between commands (again, courtesy of jeb's answer), but note how < and > needed to be ^-escaped, because the following chars. cannot be used as-is: < > | (whereas unescaped & or && or || start the next command).

  • %= <comment> =%, as detailed in dbenham's great answer, is the most flexible form, because it can be placed inside a command (among the arguments).
    It takes advantage of variable-expansion syntax in a way that ensures that the expression always expands to the empty string - as long as the comment text contains neither % nor :
    Like REM, %= <comment> =% works well both outside and inside (...) blocks, but it is more visually distinctive; the only down-sides are that it is harder to type, easier to get wrong syntactically, and not widely known, which can hinder understanding of source code that uses the technique.

Multi-line (whole-line block) comments:

• James K's answer shows how to use a goto statement and a label to delimit a multi-line comment of arbitrary length and content (which in his case he uses to store usage information).

• Zee's answer shows how to use a "null label" to create a multi-line comment, although care must be taken to terminate all interior lines with ^.

• Rob van der Woude's blog post mentions another somewhat obscure option that allows you to end a file with an arbitrary number of comment lines: An opening ( only causes everything that comes after to be ignored, as long as it doesn't contain a ( non-^-escaped) ), i.e., as long as the block is not closed.

^{[1] Using SET "foo=bar" to define variables - i.e., putting double quotes around the name and = and the value combined - is necessary in commands such as SET "foo=bar" & REM Set foo to bar., so as to ensure that what follows the intended variable value (up to the next command, in this case a single space) doesn't accidentally become part of it.
(As an aside: SET foo="bar" would not only not avoid the problem, it would make the double quotes part of the value).
Note that this problem is inherent to SET and even applies to accidental trailing whitespace following the value, so it is advisable to always use the SET "foo=bar" approach.}

Yes, as many people agreed this is the best way to iterate over a Map.

But there are chances to throw nullpointerexception if the map is null. Don't forget to put null .check in.

if x is numeric, then add scale_x_continuous(); if x is character/factor, then add scale_x_discrete(). This might solve your problem.

I also was getting the same problem but after brain storming with IIS and google for many hours. I found out the solution. This error is because some settings are disabled in IIS applicationHost.config.

Below are the steps to solution:

1. Go to C:\Windows\System32\inetsrv\config\applicationHost.config and open in notepad

2. Change the following key value present in

   • <section name="handlers" overrideModeDefault="Deny" /> change this value from "Deny" to "Allow"

   • <section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" /> change this value from "Deny" to "Allow"

It worked for me.

There is a new chronology.sty by Levi Wiseman. The documentation (pdf) says:

Most timeline packages and solutions for LATEX are used to convey a lot of information and are therefore designed vertically. If you are just attempting to assign labels to dates, a more traditional timeline might be more appropriate. That's what chronology is for.

Here is some example code:

\documentclass{article}
\usepackage{chronology}
\begin{document}

\begin{chronology}[5]{1983}{2010}{3ex}[\textwidth]
\event{1984}{one}
\event[1985]{1986}{two}
\event{\decimaldate{25}{12}{2001}}{three}
\end{chronology}

\end{document}

Which produces this output:

This example program illustrates initialization of an array of C strings.

#include <stdio.h>

const char * array[] = {
    "First entry",
    "Second entry",
    "Third entry",
};

#define n_array (sizeof (array) / sizeof (const char *))

int main ()
{
    int i;

    for (i = 0; i < n_array; i++) {
        printf ("%d: %s\n", i, array[i]);
    }
    return 0;
}

It prints out the following:

0: First entry
1: Second entry
2: Third entry

It is very sad that it is about 2020 still express hasn't added a way to render an HTML page without using sendFile method of the response object. Using sendFile is not a problem but passing argument to it in the form of path.join(__dirname, 'relative/path/to/file') doesn't feel right. Why should a user join __dirname to the file path? It should be done by default. Why can't the root of the server be by defalut the project directory? Also, installing a templating dependency just to render a static HTML file is again not correct. I don't know the correct way to tackle the issue, but if I had to serve a static HTML, then I would do something like:

const PORT = 8154;

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

app.use(express.static('views'));

app.listen(PORT, () => {
    console.log(`Server is listening at port http://localhost:${PORT}`);
});

The above example assumes that the project structure has a views directory and the static HTML files are inside it. For example, let's say, the views directory has two HTML files named index.html and about.html, then to access them, we can visit: localhost:8153/index.html or just localhost:8153/ to load the index.html page and localhost:8153/about.html to load the about.html. We can use a similar approach to serve a react/angular app by storing the artifacts in the views directory or just using the default dist/<project-name> directory and configure it in the server js as follows:

app.use(express.static('dist/<project-name>'));

Do you mean append?

>>> x = [1,2,3]
>>> y = [4,5,6]
>>> x.append(y)
>>> x
[1, 2, 3, [4, 5, 6]]

Or merge?

>>> x = [1,2,3]
>>> y = [4,5,6]
>>> x + y
[1, 2, 3, 4, 5, 6]
>>> x.extend(y)
>>> x
[1, 2, 3, 4, 5, 6] 

You can use also

select * from tablename where column1 ='a' and column2!='b';

int first = 3;  
int mid = 4; 
int last = 6;

//checks for the largest number using the Math.max(a,b) method
//for the second argument (b) you just use the same method to check which  //value is greater between the second and the third
int largest = Math.max(first, Math.max(last, mid));

using ".intValue()" on BigDecimal object is not right when you want to check if its grater than zero. The only option left is ".compareTo()" method.

One should prefere Guava over the Apache Collection (which seems to be abandoned).

Traditional relational databases were designed as client/server database systems. They can be scaled horizontally but the process to do so tends to be complex and error prone. NewSQL databases like NuoDB are memory-centric distributed database systems designed to scale out horizontally while maintaining the SQL/ACID properties of traditional RDBMS.

For more information on NuoDB, read their technical white paper.

In my case it was a proxy issue (requests proxied from nginx to a varnish cache) that caused the issue. I needed to add the following to my proxy definition

You can do this go to Settings > Storage, clicking on the setting menu icon in the top right hand corner and selecting "USB computer connection". I then changed the storage mode to "Camera (PTP)". Done try re installing the driver from device manager.

This will update all the rows in that columns if safe mode is not enabled.

UPDATE table SET columnB = columnA;

If safe mode is enabled then you will need to use a where clause. I use primary key as greater than 0 basically all will be updated

UPDATE table SET columnB = columnA where table.column>0;

This is an old topic but still top-ranked Google results and the solutions offered share the same floating point decimals issue. Here is the (very generic) function I use, thanks to MDN:

function round(value, exp) {
  if (typeof exp === 'undefined' || +exp === 0)
    return Math.round(value);

  value = +value;
  exp = +exp;

  if (isNaN(value) || !(typeof exp === 'number' && exp % 1 === 0))
    return NaN;

  // Shift
  value = value.toString().split('e');
  value = Math.round(+(value[0] + 'e' + (value[1] ? (+value[1] + exp) : exp)));

  // Shift back
  value = value.toString().split('e');
  return +(value[0] + 'e' + (value[1] ? (+value[1] - exp) : -exp));
}

As we can see, we don't get these issues:

round(1.275, 2);   // Returns 1.28
round(1.27499, 2); // Returns 1.27

This genericity also provides some cool stuff:

round(1234.5678, -2);   // Returns 1200
round(1.2345678e+2, 2); // Returns 123.46
round("123.45");        // Returns 123

Now, to answer the OP's question, one has to type:

round(10.8034, 2).toFixed(2); // Returns "10.80"
round(10.8, 2).toFixed(2);    // Returns "10.80"

Or, for a more concise, less generic function:

function round2Fixed(value) {
  value = +value;

  if (isNaN(value))
    return NaN;

  // Shift
  value = value.toString().split('e');
  value = Math.round(+(value[0] + 'e' + (value[1] ? (+value[1] + 2) : 2)));

  // Shift back
  value = value.toString().split('e');
  return (+(value[0] + 'e' + (value[1] ? (+value[1] - 2) : -2))).toFixed(2);
}

You can call it with:

round2Fixed(10.8034); // Returns "10.80"
round2Fixed(10.8);    // Returns "10.80"

if you have long processing server side code, I don't think it does fall into 404 as you said ("it goes to a webpage is not found error page")

Browser should report request timeout error.

You may do 2 things:

Based on CGI/Server side engine increase timeout there

PHP : http://www.php.net/manual/en/info.configuration.php#ini.max-execution-time - default is 30 seconds

In php.ini:

max_execution_time 60

Increase apache timeout - default is 300 (in version 2.4 it is 60).

In your httpd.conf (in server config or vhost config)

TimeOut 600

Note that first setting allows your PHP script to run longer, it will not interferre with network timeout.

Second setting modify maximum amount of time the server will wait for certain events before failing a request

Sorry, I'm not sure if you are using PHP as server side processing, but if you provide more info I will be more accurate.

Use the date function:

select date(timestamp_field) from table

From a character field representation to a date you can use:

select date(substring('2011/05/26 09:00:00' from 1 for 10));

Test code:

create table test_table (timestamp_field timestamp);
insert into test_table (timestamp_field) values(current_timestamp);
select timestamp_field, date(timestamp_field) from test_table;

Test result:

(I'm a few points shy of commenting privileges)

If you decide to forgo the +1 day in CMS's elegant solution, note that if your start date and end date are in the same weekend, you get a negative answer. Ie., 2008/10/26 to 2008/10/26 returns -1.

my rather simplistic solution:

select @Result = (..CMS's answer..)
if  (@Result < 0)
        select @Result = 0
    RETURN @Result

.. which also sets all erroneous posts with start date after end date to zero. Something you may or may not be looking for.

I have used command hcicongif with two greps to separate the PC Mac address and I saved the MAC address to variable:

PCMAC=$( hciconfig -a | grep -E 'BD Address:' | grep -Eo '[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}' )

You can also use this command to check if MAC address is in valid format. Note, that only big chars A-F are allowed and also you need to add input for this grep command:

grep -E '[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}:[A-F0-9]{2}'

Maybe the suggested solutions here worked in 2009, but ive tested all of this upvoted answers and nobody is working in any browsers.

only solution i found working is this: (but its a bit ugly to use i think)

<form method="post" name="form">
<input type="submit" value="dosomething" onclick="javascript: form.action='actionurl1';"/>
<input type="submit" value="dosomethingelse" onclick="javascript: form.action='actionurl2';"/>

The given answers are still valid. No change in SSMS (SQL Server 2016) has been made on that regard.

You can also use the criteria pane, after doing the "Edit Top 200 Rows".

1. Show criteria pane
2. Enter some criterion
3. Edit data directly in the results grid

Additionally, the number of rows for those commands can be customized in your SSMS options.

I've used this "portable plotter". It's very small, multiplatform, easy to use and you can plug it into different graphical libraries. pplot

(Only for the plots part)

If you use or plan to use Qt, another multiplatform solution is Qwt and Qchart

Use substring?

d = "2004-02-06"
substr(d,0,7)
>"2004-02"

sed -i '/^$/d' foo

This tells sed to delete every line matching the regex ^$ i.e. every empty line. The -i flag edits the file in-place, if your sed doesn't support that you can write the output to a temporary file and replace the original:

sed '/^$/d' foo > foo.tmp
mv foo.tmp foo

If you also want to remove lines consisting only of whitespace (not just empty lines) then use:

sed -i '/^[[:space:]]*$/d' foo

Edit: also remove whitespace at the end of lines, because apparently you've decided you need that too:

sed -i '/^[[:space:]]*$/d;s/[[:space:]]*$//' foo

I am using Android Studio 2.1.2. I had same requirement as OP. Though above two answer seemed to help everyone, it did not work for me . I am sharing what worked for me.

Go to main menu/Run/Edit Configuration . Select app under Android Application on the left.This should open multi-tabbed pane . Select General tab ( would be default), click green + sing at the bottom ( below text Before launch: Gradle -awake ...).

A drop down will appear, select Gradle-aware-make option. Another text box will pop up. enter :app:uninstallAll in this text box . (You can use ctrl + space to use autocomplete todetermine right target without typing everything . And also helps you choose the right app name that is avaiable for you). and set apply/ok. Relaunch your app.

Note : Every time you launch your app now , this new target will try to uninstall your app from your emulator or device. So if your testing device is not available, your launc will probably fail while uninstalling but will continue to start your emulator. So Either start your emulator first, or re-lauch after first fail again ( as first launch will start emulator though uninstall fails).

Maybe you can use ListBuffers in scala to create empty list and add strings later because ListBuffers are mutable. Also all the List functions are available for the ListBuffers in scala.

import scala.collection.mutable.ListBuffer 

val dm = ListBuffer[String]()
dm: scala.collection.mutable.ListBuffer[String] = ListBuffer()
dm += "text1"
dm += "text2"
dm = ListBuffer(text1, text2)

if you want you can convert this to a list by using .toList

Two solutions for you.

Solution 1 - Just use the key. You have not said that you can not use it. :)

<?php
    // Get the first element of this array.
    $array = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' );

    // Gets the first element by key
    $result = $array[4];

    // Expected result: string apple
    assert('$result === "apple" /* Expected result: string apple. */');
?>

Solution 2 - array_flip() + key()

<?php
    // Get first element of this array. Expected result: string apple
    $array = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' );

    // Turn values to keys
    $array = array_flip($array);

    // You might thrown a reset in just to make sure
    // that the array pointer is at the first element.
    // Also, reset returns the first element.
    // reset($myArray);

    // Return the first key
    $firstKey = key($array);

    assert('$firstKey === "apple" /* Expected result: string apple. */');
?>

Solution 3 - array_keys()

echo $array[array_keys($array)[0]];

You could also simply use a local integer variable if the lists have the same length:

List<classA> listA = fillListA();
List<classB> listB = fillListB();

var i = 0;
foreach(var itemA in listA)
{
    Console.WriteLine(itemA  + listB[i++]);
}

Yes, you can use json_encode to take your HTML string and escape it as necessary.

Note that in JSON, the top level item must be an array or object (that's not true anymore), it cannot just be a string. So you'll want to create an object and make the HTML string a property of the object (probably the only one), so the resulting JSON looks something like:

{"html": "<p>I'm the markup</p>"}

Resource-Only DLL is an option for you. But it is not required necessarily unless you want to modify resources without recompiling applications. Have just one common ResourceDictionary file is also an option. It depends how often you change resources and etc.

<ResourceDictionary Source="pack://application:,,,/
     <MyAssembly>;component/<FolderStructureInAssembly>/<ResourceFile.xaml>"/>

MyAssembly - Just assembly name without extension

FolderStructureInAssembly - If your resources are in a folde, specify folder structure

When you are doing this it's better to aware of siteOfOrigin as well.

WPF supports two authorities: application:/// and siteoforigin:///. The application:/// authority identifies application data files that are known at compile time, including resource and content files. The siteoforigin:/// authority identifies site of origin files. The scope of each authority is shown in the following figure.

There are many errors in your code, for example you are not really calling your deck by just typing deck in your Shuffle method. You can only call it by typing theCard.deck

I have changed your shuffle method:

public void Shuffle(){
    for (int i = 0; i < theCard.deck.length; i++) {
        int index = (int)(Math.random()*theCard.deck.length );
        int temp = theCard.deck[i];
        theCard.deck[i] = theCard.deck[index];
        theCard.deck[index] = temp;
        remainingCards--;
    }
}

Also, as it is said you have structural problem. You should name classes as you understand in real life, for example, when you say card, it is only one card, when you say deck it is supposed to be 52+2 cards. In this way your code would be more understandable.

That works with :

 var element = document.getElementById('myElem');
 if (typeof (element) != undefined && typeof (element) != null && typeof (element) != 'undefined') {
     console.log('element exists');
 }
 else{
     console.log('element NOT exists');
 }

Same as any other language, just pass index number of element that you want to retrieve.

#!/usr/bin/env python
x = [2,3,4,5,6,7]
print(x[5])

First you have to ensure that there is a SMTP server listening on port 25.

To look whether you have the service, you can try using TELNET client, such as:

C:\> telnet localhost 25

(telnet client by default is disabled on most recent versions of Windows, you have to add/enable the Windows component from Control Panel. In Linux/UNIX usually telnet client is there by default.

$ telnet localhost 25

If it waits for long then time out, that means you don't have the required SMTP service. If successfully connected you enter something and able to type something, the service is there.

If you don't have the service, you can use these:

• A mock SMTP server that will mimic the behavior of actual SMTP server, as you are using Java, it is natural to suggest Dumbster fake SMTP server. This even can be made to work within JUnit tests (with setup/tear down/validation), or independently run as separate process for integration test.
• If your host is Windows, you can try installing Mercury email server (also comes with WAMPP package from Apache Friends) on your local before running above code.
• If your host is Linux or UNIX, try to enable the mail service such as Postfix,
• Another full blown SMTP server in Java, such as Apache James mail server.

If you are sure that you already have the service, may be the SMTP requires additional security credentials. If you can tell me what SMTP server listening on port 25 I may be able to tell you more.

OID's are still in use for Postgres with large objects (though some people would argue large objects are not generally useful anyway). They are also used extensively by system tables. They are used for instance by TOAST which stores larger than 8KB BYTEA's (etc.) off to a separate storage area (transparently) which is used by default by all tables. Their direct use associated with "normal" user tables is basically deprecated.

The oid type is currently implemented as an unsigned four-byte integer. Therefore, it is not large enough to provide database-wide uniqueness in large databases, or even in large individual tables. So, using a user-created table's OID column as a primary key is discouraged. OIDs are best used only for references to system tables.

Apparently the OID sequence "does" wrap if it exceeds 4B 6. So in essence it's a global counter that can wrap. If it does wrap, some slowdown may start occurring when it's used and "searched" for unique values, etc.

See also https://wiki.postgresql.org/wiki/FAQ#What_is_an_OID.3F

I had a similar situation. However I used a different solution.

In my model I create a property that does the dictionary lookup. In the template I then use the property.

In my model: -

@property
def state_(self):
    """ Return the text of the state rather than an integer """
    return self.STATE[self.state]

In my template: -

The state is: {{ item.state_ }}

Abstraction is the process where you "throw-away" unnecessary details from an entity you plan to capture/represent in your design and keep only the properties of the entity that are relevant to your domain.
Example: to represent car you would keep e.g. the model and price, current location and current speed and ignore color and number of seats etc.

Encapsulation is the "binding" of the properties and the operations that manipulate them in a single unit of abstraction (namely a class).
So the car would have accelarate stop that manipulate location and current speed etc.

Simple declaration of the StringHttpMessageConverter bean is not enough, you need to inject it into AnnotationMethodHandlerAdapter:

<bean class = "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <array>
            <bean class = "org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" />
            </bean>
        </array>
    </property>
</bean>

However, using this method you have to redefine all HttpMessageConverters, and also it doesn't work with <mvc:annotation-driven />.

So, perhaps the most convenient but ugly method is to intercept instantiation of the AnnotationMethodHandlerAdapter with BeanPostProcessor:

public class EncodingPostProcessor implements BeanPostProcessor {
    public Object postProcessBeforeInitialization(Object bean, String name)
            throws BeansException {
        if (bean instanceof AnnotationMethodHandlerAdapter) {
            HttpMessageConverter<?>[] convs = ((AnnotationMethodHandlerAdapter) bean).getMessageConverters();
            for (HttpMessageConverter<?> conv: convs) {
                if (conv instanceof StringHttpMessageConverter) {
                    ((StringHttpMessageConverter) conv).setSupportedMediaTypes(
                        Arrays.asList(new MediaType("text", "html", 
                            Charset.forName("UTF-8"))));
                }
            }
        }
        return bean;
    }

    public Object postProcessAfterInitialization(Object bean, String name)
            throws BeansException {
        return bean;
    }
}

-

<bean class = "EncodingPostProcessor " />

Apache has ArithmeticUtils.pow(int k, int e).

$ens = $em->getRepository('AcmeBinBundle:Marks')
              ->findBy(
                 array(), 
                 array('id' => 'ASC')
               );

I had the same issue while following the Laravel docs (https://laravel.com/docs/5.2/homestead)

My problem was very simple, I missed read this part in the docs:

Homestead.yaml file will be placed in the ~/.homestead hidden directory:

So I was updating the wrong Homestead.yaml file, since the file was moved when I ran the bash init.sh command.

I only realised this after a lot of searching, so hope this will help someone.

Nginx prefers prefix-based location matches (not involving regular expression), that's why in your code block, /stash redirects are going to /.

The algorithm used by Nginx to select which location to use is described thoroughly here: https://www.digitalocean.com/community/tutorials/understanding-nginx-server-and-location-block-selection-algorithms#matching-location-blocks

add display:block; and it'll work. Images are inline by default

To clarify, the default width for a block element is auto, which of course fills the entire available width of the containing element.

By setting the margin to auto, the browser assigns half the remaining space to margin-left and the other half to margin-right.

I think you want to change the setting called "DropDownStyle" to be "DropDownList".

Make sure you concatenate the multiple emails with ',' instead of ';'

# tar all files within and deeper in a given directory
# with no prefixes ( neither <directory>/ nor ./ )
# parameters: <source directory> <target archive file>
function tar_all_in_dir {
    { cd "$1" && find -type f -print0; } \
    | cut --zero-terminated --characters=3- \
    | tar --create --file="$2" --directory="$1" --null --files-from=-
}

Safely handles filenames with spaces or other unusual characters. You can optionally add a -name '*.sql' or similar filter to the find command to limit the files included.

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

I also had this problem and I solved it inserting my Flutter SDK path which was

C:\...\flutter_windows_v0.6.0-beta\flutter

Download it from here:

http://www.iis.net/downloads/microsoft/url-rewrite

or if you already have Web Platform Installer on your machine you can install it from there.

You can create an Int Array like this:

val numbers = IntArray(5, { 10 * (it + 1) })

5 is the Int Array size. the lambda function is the element init function. 'it' range in [0,4], plus 1 make range in [1,5]

origin function is:

 /**
 * An array of ints. When targeting the JVM, instances of this class are 
 * represented as `int[]`.
 * @constructor Creates a new array of the specified [size], with all elements 
 *  initialized to zero.
 */
 public class IntArray(size: Int) {
       /**
        * Creates a new array of the specified [size], where each element is 
        * calculated by calling the specified
        * [init] function. The [init] function returns an array element given 
        * its index.
        */
      public inline constructor(size: Int, init: (Int) -> Int)
  ...
 }

IntArray class defined in the Arrays.kt

Slicing:

x = [0,1,2,3,4]
x = x[1:]

Which would actually return a subset of the original but not modify it.

There is a whole new approach that you may want to consider if what you're after is the power and performance of stored procedures, and the rapid development that tools like Entity Framework provide.

I've taken SQL+ for a test drive on a small project, and it is really something special. You basically add what amounts to comments to your SQL routines, and those comments provide instructions to a code generator, which then builds a really nice object oriented class library based on the actual SQL routine. Kind of like entity framework in reverse.

Input parameters become part of an input object, output parameters and result sets become part of an output object, and a service component provides the method calls.

If you want to use stored procedures, but still want rapid development, you might want to have a look at this stuff.

Which alignment technique you use depends on your circumstances but the basic one is float: right;:

<input type="button" value="Click Me" style="float: right;">

You'll probably want to clear your floats though but that can be done with overflow:hidden on the parent container or an explicit <div style="clear: both;"></div> at the bottom of the container.

For example: http://jsfiddle.net/ambiguous/8UvVg/

Floated elements are removed from the normal document flow so they can overflow their parent's boundary and mess up the parent's height, the clear:both CSS takes care of that (as does overflow:hidden). Play around with the JSFiddle example I added to see how floating and clearing behave (you'll want to drop the overflow:hidden first though).

I've modified Foxidrive's answer to copy entire folders and all their contents. this script will create a folder and backup another folder's contents into it, including any subfolders underneath.

If you put this in say an hourly scheduled task you need to be careful as you could fill up your drive quickly with copies of your original folder. Before bitbucket etc i was using as similar script to save my code offline.

@echo off
for /f "delims=" %%a in ('wmic OS Get localdatetime  ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set HH=%dt:~8,2%
set Min=%dt:~10,2%
set Sec=%dt:~12,2%

set stamp=YourPrefixHere_%YYYY%%MM%%DD%@%HH%%Min%
rem you could for example want to create a folder in Gdrive and save backup there
cd C:\YourGoogleDriveFolder
mkdir %stamp%
cd %stamp%

 xcopy C:\FolderWithDataToBackup\*.* /s 

After running around in the Preferences dialog, the following is the location at which the highlight color for "occurrences" can be changed:

General -> Editors -> Text Editors -> Annotations

Look for Occurences from the Annotation types list.

Then, be sure that Text as highlighted is selected, then choose the desired color.

By design, getRequestURL() gives you the full URL, missing only the query string.

In HttpServletRequest, you can get individual parts of the URI using the methods below:

// Example: http://myhost:8080/people?lastname=Fox&age=30

String uri = request.getScheme() + "://" +   // "http" + "://
             request.getServerName() +       // "myhost"
             ":" +                           // ":"
             request.getServerPort() +       // "8080"
             request.getRequestURI() +       // "/people"
             "?" +                           // "?"
             request.getQueryString();       // "lastname=Fox&age=30"

• .getScheme() will give you "https" if it was a https://domain request.
• .getServerName() gives domain on http(s)://domain.
• .getServerPort() will give you the port.

Use the snippet below:

String uri = request.getScheme() + "://" +
             request.getServerName() + 
             ("http".equals(request.getScheme()) && request.getServerPort() == 80 || "https".equals(request.getScheme()) && request.getServerPort() == 443 ? "" : ":" + request.getServerPort() ) +
             request.getRequestURI() +
            (request.getQueryString() != null ? "?" + request.getQueryString() : "");

This snippet above will get the full URI, hiding the port if the default one was used, and not adding the "?" and the query string if the latter was not provided.

Proxied requests

Note, that if your request passes through a proxy, you need to look at the X-Forwarded-Proto header since the scheme might be altered:

request.getHeader("X-Forwarded-Proto")

Also, a common header is X-Forwarded-For, which show the original request IP instead of the proxys IP.

request.getHeader("X-Forwarded-For")

If you are responsible for the configuration of the proxy/load balancer yourself, you need to ensure that these headers are set upon forwarding.

If you are trying to redirect after the headers have been sent (if, for instance, you are doing an error redirect from a partially-generated page), you can send some client Javascript (location.replace or location.href, etc.) to redirect to whatever URL you want. Of course, that depends on what HTML has already been sent down.

• To remove white spaces:

1) To remove white space everywhere:

df.columns = df.columns.str.replace(' ', '')

2) To remove white space at the beginning of string:

df.columns = df.columns.str.lstrip()

3) To remove white space at the end of string:

df.columns = df.columns.str.rstrip()

4) To remove white space at both ends:

df.columns = df.columns.str.strip()

• To replace white spaces with other characters (underscore for instance):

5) To replace white space everywhere

df.columns = df.columns.str.replace(' ', '_')

6) To replace white space at the beginning:

df.columns = df.columns.str.replace('^ +', '_')

7) To replace white space at the end:

df.columns = df.columns.str.replace(' +$', '_')

8) To replace white space at both ends:

df.columns = df.columns.str.replace('^ +| +$', '_')

All above applies to a specific column as well, assume you have a column named col, then just do:

df[col] = df[col].str.strip()  # or .replace as above

Use print_r($votes); to inspect the array $votes, you will see that key 0 does not exist there. It will return NULL and throw that error.

Hi Just addition to VonC comments. I am using ecj compiler to compile my project. it was throwing expcetion that some of the classes are not found. But the project was bulding fine with javac compiler.

So just I added the classes into the classpath(which we have to pass as argument) and now its working fine... :)

As parents() returns a list, this also works

$('#element').parents()[3];

You can have multiple .gitignore, each one of course in its own directory.
To check which gitignore rule is responsible for ignoring a file, use git check-ignore: git check-ignore -v -- afile.

And you can have different version of a .gitignore file per branch: I have already seen that kind of configuration for ensuring one branch ignores a file while the other branch does not: see this question for instance.

If your repo includes several independent projects, it would be best to reference them as submodules though.
That would be the actual best practices, allowing each of those projects to be cloned independently (with their respective .gitignore files), while being referenced by a specific revision in a global parent project.
See true nature of submodules for more.

Note that, since git 1.8.2 (March 2013) you can do a git check-ignore -v -- yourfile in order to see which gitignore run (from which .gitignore file) is applied to 'yourfile', and better understand why said file is ignored.
See "which gitignore rule is ignoring my file?"

If you are on Linux:

sudo service virtualbox restart

.a files are created with the ar utility, and they are libraries. To use it with gcc, collect all .a files in a lib/ folder and then link with -L lib/ and -l<name of specific library>.

Collection of all .a files into lib/ is optional. Doing so makes for better looking directories with nice separation of code and libraries, IMHO.

I was facing the same issue. I tried the following and it worked. installing for Mac OS X, anaconda python 2.7

pip uninstall tensorflow export TF_BINARY_URL=<get the correct url from http://tflearn.org/installation/> pip install --upgrade $TF_BINARY_URL

Installed tensorflow-1.0.0

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.

Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.

You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.

You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.

    }

$final_array = array_combine($a, $a);

Reference: http://php.net/array-combine

P.S. Be careful with source array containing duplicated keys like the following:

$a = ['one','two','one'];

Note the duplicated one element.

If you intend to use this output in production, then use the Trace class members. This makes the code portable, you can wire up different types of listeners and output to the console window, debug window, log file, or whatever else you like.

If this is just some temporary debugging code that you're using to verify that certain code is being executed or has the correct values, then use the Debug class as Zach suggests.

If you absolutely must use the console, then you can attach a console in the program's Main method.

Ensure these two and it should work:-

1. Python, Oracle instantclient and cx_Oracle are 32 bit.
2. Set the environment variables.

Fixes this issue on windows like a charm.

A year later, stumbled across this question for a inline LI problem, but have found a great solution that may apply here.

http://robertnyman.com/2010/02/24/css-display-inline-block-why-it-rocks-and-why-it-sucks/

vertical-align:bottom on all my LI elements fixed my "extra margin" problem in all browsers.

s.length() - s.replaceAll(" ", "").length() returns you number of spaces.

There are more ways. For example"

int spaceCount = 0;
for (char c : str.toCharArray()) {
    if (c == ' ') {
         spaceCount++;
    }
}

etc., etc.

In your case you tried to split string using \t - TAB. You will get right result if you use " " instead. Using \s may be confusing since it matches all whitepsaces - regular spaces and TABs.

just follow this step (i am not writing code just Bcoz you may do copy and paste and cant learn)..

1. first at all you need to declare a button which you have in layout

2. Give reference to that button by finding its id (using findviewById) in oncreate

3. setlistener for button (like setonclick listener)

4. last handle the click event (means start new activity by using intent as you know already)

5. Dont forget to add activity in manifest file

BTW this is just simple i would like to suggest you that just start from simple tutorials available on net will be better for you..

Best luck for Android

No, it doesn't save you memory.

Also note that you don't have to import Math at all. Everything in java.lang is imported automatically.

A better example would be something like an ArrayList

import java.util.ArrayList;
....
ArrayList<String> i = new ArrayList<String>();

Note I'm importing the ArrayList specifically. I could have done

import java.util.*; 

But you generally want to avoid large wildcard imports to avoid the problem of collisions between packages.

Note that the NSString stringWithContentsOfURL will report a totally different user-agent string than the UIWebView making the same request. So if your server is user-agent aware, and sending back different html depending on who is asking for it, you may not get correct results this way.

Also note that the @"document.body.innerHTML" mentioned above will only display what is in the body tag. If you use @"document.all[0].innerHTML" you will get both head and body. Which is still not the complete contents of the UIWebView, since it will not get back the !doctype or html tags, but it is a lot closer.

An alternative to the accepted answer that fits in the first line:

#!/bin/bash -e

cd some_dir  

./configure --some-flags  

make  

make install

This has been driving me crazy, but I finally put all the pieces together. As of 1/25/2015, I've confirmed that it is possible to list the images in the docker V2 registry ( exactly as @jonatan mentioned, above. )

I would up-vote that answer, if I had the rep for it.

Instead, I'll expand on the answer. Since registry V2 is made with security in mind, I think it's appropriate to include how to set it up with a self signed cert, and run the container with that cert in order that an https call can be made to it with that cert:

This is the script I actually use to start the registry:

sudo docker stop registry
sudo docker rm -v registry
sudo docker run -d \
  -p 5001:5001 \
  -p 5000:5000 \
  --restart=always \
  --name registry \
  -v /data/registry:/var/lib/registry \
  -v /root/certs:/certs \
  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
  -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \ 
  -e REGISTRY_HTTP_DEBUG_ADDR=':5001' \
  registry:2.2.1

This may be obvious to some, but I always get mixed up with keys and certs. The file that needs to be referenced to make the call @jonaton mentions above**, is the domain.crt listed above. ( Since I put domain.crt in /root, I made a copy into the user directory where it could be accessed. )

curl --cacert ~/domain.crt https://myregistry:5000/v2/_catalog
> {"repositories":["redis","ubuntu"]}

**The command above has been changed: -X GET didn't actually work when I tried it.

Note: https://myregistry:5000 ( as above ) must match the domain given to the cert generated.

I meet the same problem today, and solve it by the code follows.

html code:

<div style='display: none'>
  <img id='img' src='img/iak.png' width='600' height='400' />
</div>
<canvas id='iak'>broswer don't support canvas</canvas>

js code:

var canvas = document.getElementById('iak')
var iakImg = document.getElementById('img')
var ctx = canvas.getContext('2d')
var image = new Image()
image.src=iakImg.src
image.onload = function () {
   ctx.drawImage(image,0,0)
   var data = ctx.getImageData(0,0,600,400)
}

code like above, and there is no cross-domain problem.

In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.

  def change
    change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13
    change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13
  end

You can do this: add oldvalue attribute to html element, add set oldvalue when user click. Then onchange event use oldvalue.

<input type="text" id="test" value ="ABS" onchange="onChangeTest(this)" onclick="setoldvalue(this)" oldvalue="">

<script>
function setoldvalue(element){
   element.setAttribute("oldvalue",this.value);
}

function onChangeTest(element){
   element.setAttribute("value",this.getAttribute("oldvalue"));
}
</script>

Assuming your json object from your GET request looks like the one you posted above simply do:

let list: string[] = [];

json.Results.forEach(element => {
    list.push(element.Id);
});

Or am I missing something that prevents you from doing it this way?

Try having this in your xml of Edit Text:

android:inputType="numberDecimal"

Copy the downloaded DLL file in a custom folder on your dev drive, then add the reference to your project using the Browse button in the Add Reference dialog.
Be sure that the new reference has the Copy Local = True.
The Add Reference dialog could be opened right-clicking on the References item in your project in Solution Explorer

UPDATE AFTER SOME YEARS
At the present time the best way to resolve all those problems is through the
Manage NuGet packages menu command of Visual Studio 2017/2019.
You can right click on the References node of your project and select that command. From the Browse tab search for the library you want to use in the NuGet repository, click on the item if found and then Install it. (Of course you need to have a package for that DLL and this is not guaranteed to exist)

Just adding .First to your bananaToken should do it:
foodJsonObj["food"]["fruit"]["orange"].Parent.AddAfterSelf(bananaToken .First);
.First basically moves past the { to make it a JProperty instead of a JToken.

@Brian Rogers, Thanks I forgot the .Parent. Edited

Differences might not be meaningful in a typical use case, but using the standard DOM functionality

$("#el")[0].outerHTML

is about twice as fast as

$("<div />").append($("#el").clone()).html();

so I would go with:

/* 
 * Return outerHTML for the first element in a jQuery object,
 * or an empty string if the jQuery object is empty;  
 */
jQuery.fn.outerHTML = function() {
   return (this[0]) ? this[0].outerHTML : '';  
};

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

Use

<ScrollView 
 onMomentumScrollEnd={(event) => this.getscrollposition(event)} 
 scrollEventThrottle={16}>

Show Position

getscrollposition(e) {console.log('scroll y ', e.nativeEvent.contentOffset.y);}

For those who want some background info, here's a short article explaining why overflow: hidden works. It has to do with the so-called block formatting context. This is part of W3C's spec (ie is not a hack) and is basically the region occupied by an element with a block-type flow.

Every time it is applied, overflow: hidden creates a new block formatting context. But it's not the only property capable of triggering that behaviour. Quoting a presentation by Fiona Chan from Sydney Web Apps Group:

• float: left / right
• overflow: hidden / auto / scroll
• display: table-cell and any table-related values / inline-block
• position: absolute / fixed

First, get Pdftk:

sudo apt-get install pdftk

Now, as shown on example page, use

pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf

for merging pdf files into one.

Let us assume you have a margin-bottom property set to 20px / 20% / 20em. To get the value as a number there are two options:

Option 1:

parseInt($('#some_DOM_element_ID').css('margin-bottom'), 10);

The parseInt() function parses a string and returns an integer. Don't change the 10 found in the above function (known as a "radix") unless you know what you are doing.

Example Output will be: 20 (if margin-bottom set in px) for % and em it will output the relative number based on current Parent Element / Font size.

Option 2 (I personally prefer this option)

parseFloat($('#some_DOM_element_ID').css('margin-bottom'));

Example Output will be: 20 (if margin-bottom set in px) for % and em it will output the relative number based on current Parent Element / Font size.

The parseFloat() function parses a string and returns a floating point number.

The parseFloat() function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string.

The advantage of Option 2 is that if you get decimal numbers returned (e.g. 20.32322px) you will get the number returned with the values behind the decimal point. Useful if you need specific numbers returned, for example if your margin-bottom is set in em or %

Try overriding and returning true from either onInterceptTouchEvent() and/or onTouchEvent(), which will consume touch events on the pager.

$("#element").validate().valid()

Though I am very late in this discussion, I thought this may be useful for some one in future.

I had faced similar situation. The easiest workaround for those who doesn't mind unsetting and resetting the variable is to do so. I am pretty sure the reason why this is not working is clear from the other answers and from the php.net manual. The simplest workaround worked for me is

Assumption:

1. $object is the object with overloaded __get and __set from the base class, which I am not in the freedom to modify.
2. shippingData is the array I want to modify a field of for e.g. :- phone_number

// First store the array in a local variable.
$tempShippingData = $object->shippingData;

unset($object->shippingData);

$tempShippingData['phone_number'] = '888-666-0000' // what ever the value you want to set

$object->shippingData = $tempShippingData; // this will again call the __set and set the array variable

unset($tempShippingData);

Note: this solution is one of the quick workaround possible to solve the problem and get the variable copied. If the array is too humungous, it may be good to force rewrite the __get method to return a reference rather expensive copying of big arrays.

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

The code pasted by Rivers is great. Thanks a lot! I'm new here and can't comment, I'd just want to answer to the question from javiervd (How would you set the screen_name and count with this approach?), as I've lost a lot of time to figure it out.

You need to add the parameters both to the URL and to the signature creating process. Creating a signature is the article that helped me. Here is my code:

$oauth = array(
           'screen_name' => 'DwightHoward',
           'count' => 2,
           'oauth_consumer_key' => $consumer_key,
           'oauth_nonce' => time(),
           'oauth_signature_method' => 'HMAC-SHA1',
           'oauth_token' => $oauth_access_token,
           'oauth_timestamp' => time(),
           'oauth_version' => '1.0'
         );

$options = array(
             CURLOPT_HTTPHEADER => $header,
             //CURLOPT_POSTFIELDS => $postfields,
             CURLOPT_HEADER => false,
             CURLOPT_URL => $url . '?screen_name=DwightHoward&count=2',
             CURLOPT_RETURNTRANSFER => true, CURLOPT_SSL_VERIFYPEER => false
           );

You can convert a string to a date easily by:

CAST(YourDate AS DATE)

There are multiple methods of creating date as discussed above. I would not repeat same stuff. Here is small method to convert String to Date in Java Script if that is what you are looking for,

function compareDate(str1){
// str1 format should be dd/mm/yyyy. Separator can be anything e.g. / or -. It wont effect
var dt1   = parseInt(str1.substring(0,2));
var mon1  = parseInt(str1.substring(3,5));
var yr1   = parseInt(str1.substring(6,10));
var date1 = new Date(yr1, mon1-1, dt1);
return date1;
}

If you are using Windows S.O. make sure it is in the folder:

C:\Users\**your-user-name**\AppData\Local\Android\Sdk\platform-tools

Otherwise, open Android Studio and go to:

Tools> SDK Manager> Android SDK> SDK Tools

Select the Android Platform-Tools and Android SDK Tools checkbox and click Apply. After download check the directory again.

I believe all the existing answers contain the relevant information, but I would like to summarize.

The response object that is returned by requests get and post operations contains two useful attributes:

Response attributes

• response.text - Contains str with the response text.
• response.content - Contains bytes with the raw response content.

You should choose one or other of these attributes depending on the type of response you expect.

• For text-based responses (html, json, yaml, etc) you would use response.text
• For binary-based responses (jpg, png, zip, xls, etc) you would use response.content.

Writing response to file

When writing responses to file you need to use the open function with the appropriate file write mode.

• For text responses you need to use "w" - plain write mode.
• For binary responses you need to use "wb" - binary write mode.

Examples

Text request and save

# Request the HTML for this web page:
response = requests.get("https://stackoverflow.com/questions/31126596/saving-response-from-requests-to-file")
with open("response.txt", "w") as f:
    f.write(response.text)

Binary request and save

# Request the profile picture of the OP:
response = requests.get("https://i.stack.imgur.com/iysmF.jpg?s=32&g=1")
with open("response.jpg", "wb") as f:
    f.write(response.content)

Answering the original question

The original code should work by using wb and response.content:

import requests

files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("out.xls", "wb")
file.write(response.content)
file.close()

But I would go further and use the with context manager for open.

import requests

with open('1.pdf', 'rb') as file:
    files = {'f': ('1.pdf', file)}
    response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)

response.raise_for_status() # ensure we notice bad responses

with open("out.xls", "wb") as file:
    file.write(response.content)

If the above solution does not work for you it is may be possible to obtain the same result with the following pure nodejs code. The above did not work for me and resulted in a compilation exception when running 'npm install iconv' on OSX:

fs.readFileSync() returns a Buffer if no encoding is specified. And Buffer has a toString() method that will convert to UTF8 if no encoding is specified giving you the file's contents. See the nodejs documentation. This worked for me.

You have to validate the connection.

If you use Oracle it is likely that you use Oracle´s Universal Connection Pool. The following assumes that you do so.

The easiest way to validate the connection is to tell Oracle that the connection must be validated while borrowing it. This can be done with

pool.setValidateConnectionOnBorrow(true);

But it works only if you hold the connection for a short period. If you borrow the connection for a longer time, it is likely that the connection gets broken while you hold it. In that case you have to validate the connection explicitly with

if (connection == null || !((ValidConnection) connection).isValid())

See the Oracle documentation for further details.

Like the others said:

inputString.split('\n')  # --> ['Line 1', 'Line 2', 'Line 3']

This is identical to the above, but the string module's functions are deprecated and should be avoided:

import string
string.split(inputString, '\n')  # --> ['Line 1', 'Line 2', 'Line 3']

Alternatively, if you want each line to include the break sequence (CR,LF,CRLF), use the splitlines method with a True argument:

inputString.splitlines(True)  # --> ['Line 1\n', 'Line 2\n', 'Line 3']

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

I was looking for the answer to the same question and came across this topic. I see two main ways: the combination of array_search & unset and the use of array_diff. At first glance, it seemed to me that the first method would be faster, since does not require the creation of an additional array (as when using array_diff). But I wrote a small benchmark and made sure that the second method is not only more concise, but also faster! Glad to share this with you. :)

You can do it using xml.

Create an xml layout and name it like my_edit_text_border.xml

 <?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#ffffff"/>
            <corners android:radius="5dp" />
            <stroke
                android:width="2dp"
                android:color="#949494"
                />
        </shape>
    </item>
</selector>

Add background to your Edittext

<EditText
 android:id="@+id/editText1"

 android:background="@layout/my_edit_text_border">

I've mixed and matched from different schemes I've seen and based on the tooling I'm using.
So my completed branch name would be:

name/feature/issue-tracker-number/short-description

which would translate to:

mike/blogs/RSSI-12/logo-fix

The parts are separated by forward slashes because those get interpreted as folders in SourceTree for easy organization. We use Jira for our issue tracking so including the number makes it easier to look up in the system. Including that number also makes it searchable when trying to find that issue inside Github when trying to submit a pull request.

I agree css is better. If you did want to do it via Xpath you could try:

    String kk = wd.findElement(By.xpath(.//*div[@id='customSelect_3']/div/span[@class='selectLabel clear'].getText()))

The below css code always keep the button at the bottom of the page

position:absolute;
bottom:0;

Since you want to do it in relative positioning, you should go for margin-top:100%

position:relative;
margin-top:100%;

EDIT1: JSFiddle1

EDIT2: To place button at center of the screen,

position:relative;
left: 50%;
margin-top:50%;

Simple fundamentals, Elastic community has exposed indexing, searching, deleting operation as rest web service. You can interact elastic using curl or sense(chrome plugin) or any rest client like postman.

If you are just testing few commands, I would recommend can use of sense chrome plugin which has simple UI and pretty mature plugin now.

I tested your code and works properly. I've added a small demo with another way to print all the data in the map:

ConcurrentHashMap<String, Integer> map = new ConcurrentHashMap<String, Integer>();
map.put("A", 1);
map.put("B", 2);
map.put("C", 3);

for (String key : map.keySet()) {
    System.out.println(key + " " + map.get(key));
}

for (Map.Entry<String, Integer> entry : map.entrySet()) {
    String key = entry.getKey().toString();
    Integer value = entry.getValue();
    System.out.println("key, " + key + " value " + value);
}

Here's how I usually do it. For example, to calculate 1717 mod 2:

• Take 1717 / 2. The answer is 858.5
• Now take 858 and multiply it by the mod (2) to get 1716
• Finally, subtract the original number (1717) minus the number you got from the previous step (1716) -- 1717-1716=1.

So 1717 mod 2 is 1.

To sum this up all you have to do is multiply the numbers before the decimal point with the mod then subtract it from the original number.

You have more going on than you said. I ran the following expanded test from your example:

public class test {

    public static void main(String[] args) {
        Object[][] someArray = new Object[5][];
        someArray[0] = new Object[10];
        someArray[1] = null;
        someArray[2] = new Object[1];
        someArray[3] = null;
        someArray[4] = new Object[5];

        for (int i=0; i<=someArray.length-1; i++) {
            if (someArray[i] != null) {
                System.out.println("not null");
            } else {
                System.out.println("null");
            }
        }
    }
}

and got the expected output:

$ /cygdrive/c/Program\ Files/Java/jdk1.6.0_03/bin/java -cp . test
not null
null
not null
null
not null

Are you possibly trying to check the lengths of someArray[index]?

Please follow the below example:

public enum ErrorCodes {
NO_File("No file found. "),
private ErrorCodes(String value) { 
    this.errordesc = value; 
    }
private String errordesc = ""; 
public String errordesc() {
    return errordesc;
}
public void setValue(String errordesc) {
    this.errordesc = errordesc;
}

};

In your code call it like:

fileResponse.setErrorCode(ErrorCodes.NO_FILE.errordesc());

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

$('#div1').attr('class')

will return a string of the classes. Turn it into an array of class names

var classNames = $('#div1').attr('class').split(' ');

Had a similar problem with a ghost table. Thankfully had an SQL dump from before the failure.

In my case, I had to:

1. Stop mySQL
2. Move ib* files from /var/mysql off to a backup
3. Delete /var/mysql/{dbname}
4. Restart mySQL
5. Recreate empty database
6. Restore dump file

NOTE: Requires dump file.

In vi, J (that's Shift + J) or :join should do what you want, for the most part. Note that they adjust whitespace. In particular, you'll end up with a space between the two joined lines in many cases, and if the second line is indented that indentation will be removed prior to joining.

In Vim you can also use gJ (G, then Shift + J) or :join!. These will join lines without doing any whitespace adjustments.

In Vim, see :help J for more information.

The web server is prompting you for a SPNEGO (Simple and Protected GSSAPI Negotiation Mechanism) token.

This is a Microsoft invention for negotiating a type of authentication to use for Web SSO (single-sign-on):

• either NTLM
• or Kerberos.

See:

• Microsoft MSDN Library: HTTP-Based Cross-Platform Authentication by Using the Negotiate Protocol
• RFC 4178: The Simple and Protected Generic Security Service Application Program Interface (GSS-API) Negotiation Mechanism

Assign fx:id or declare variable to/of any node: anchorpane, button, etc. Then add event handler to it and within that event handler insert the given code below:

Stage stage = (Stage)((Node)((EventObject) eventVariable).getSource()).getScene().getWindow();

Hope, this works for you!!

For Linux and OSX

Step 1: Download chromedriver

# You can find more recent/older versions at http://chromedriver.storage.googleapis.com/
# Also make sure to pick the right driver, based on your Operating System
wget http://chromedriver.storage.googleapis.com/81.0.4044.69/chromedriver_mac64.zip

For debian: wget https://chromedriver.storage.googleapis.com/2.41/chromedriver_linux64.zip

Step 2: Add chromedriver to /usr/local/bin

unzip chromedriver_mac64.zip
sudo mv chromedriver /usr/local/bin
sudo chown root:root /usr/local/bin/chromedriver
sudo chmod +x /usr/local/bin/chromedriver

You should now be able to run

from selenium import webdriver

browser = webdriver.Chrome()
browser.get('http://localhost:8000')

without any issues

Michael's suggestion of running your own nbviewer instance is a good one I used in the past with an Enterprise Github server.

Another lightweight alternative is to have a cell at the end of your notebook that does a shell call to nbconvert so that it's automatically refreshed after running the whole thing:

!ipython nbconvert <notebook name>.ipynb --to html

EDIT: With Jupyter/IPython's Big Split, you'll probably want to change this to !jupyter nbconvert <notebook name>.ipynb --to html now.

We use Oracle PL/SQL Developer(Version 12.0.7). And we use F5 button to view the explain plan.

The following configs works on Cent OS 6 or earlier

As stated above first have to disable selinux.

Step 1 nano /etc/sysconfig/selinux

Make sure the file has this configurations

SELINUX=disabled

SELINUXTYPE=targeted

Then restart the system

Step 2

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

Step 3

sudo service iptables save

For Cent OS 7

step 1

firewall-cmd --zone=public --permanent --add-port=8080/tcp

Step 2

firewall-cmd --reload

Here is a solution am using with anular 6.

[readonly]="DateRelatedObject.bool_DatesEdit ? true : false"

plus above given answer

[attr.disabled]="valid == true ? true : null"

did't work for me plus be aware of using null cause it's expecting bool.

In Windows, you can use any combination of red green and blue on the foreground (text) and the background.

/* you can use these constants
FOREGROUND_BLUE
FOREGROUND_GREEN
FOREGROUND_RED
FOREGROUND_INTENSITY
BACKGROUND_BLUE
BACKGROUND_GREEN
BACKGROUND_RED
BACKGROUND_INTENSITY
*/

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
std::cout << "I'm cyan! Who are you?" << std::endl;

Wikipedia is built on MediaWiki, and here's the MediaWiki API.

More compact version working with spaces and newlines in the file name:

find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;

Use UNSIGNED for non-negative integers.
