There is no way to identify the charset of a string that is completely accurate. There are ways to try to guess the charset. One of these ways, and probably/currently the best in PHP, is mb_detect_encoding(). This will scan your string and look for occurrences of stuff unique to certain charsets. Depending on your string, there may not be such distinguishable occurrences.

Take the ISO-8859-1 charset vs ISO-8859-15 ( http://en.wikipedia.org/wiki/ISO/IEC_8859-15#Changes_from_ISO-8859-1 )

There's only a handful of different characters, and to make it worse, they're represented by the same bytes. There is no way to detect, being given a string without knowing it's encoding, whether byte 0xA4 is supposed to signify ¤ or € in your string, so there is no way to know it's exact charset.

(Note: you could add a human factor, or an even more advanced scanning technique (e.g. what Oroboros102 suggests), to try to figure out based upon the surrounding context, if the character should be ¤ or €, though this seems like a bridge too far)

There are more distinguishable differences between e.g. UTF-8 and ISO-8859-1, so it's still worth trying to figure it out when you're unsure, though you can and should never rely on it being correct.

Interesting read: http://kore-nordmann.de/blog/php_charset_encoding_FAQ.html#how-do-i-determine-the-charset-encoding-of-a-string

There are other ways of ensuring the correct charset though. Concerning forms, try to enforce UTF-8 as much as possible (check out snowman to make sure yout submission will be UTF-8 in every browser: http://intertwingly.net/blog/2010/07/29/Rails-and-Snowmen ) That being done, at least you're can be sure that every text submitted through your forms is utf_8. Concerning uploaded files, try running the unix 'file -i' command on it through e.g. exec() (if possible on your server) to aid the detection (using the document's BOM.) Concerning scraping data, you could read the HTTP headers, that usually specify the charset. When parsing XML files, see if the XML meta-data contain a charset definition.

Rather than trying to automagically guess the charset, you should first try to ensure a certain charset yourself where possible, or trying to grab a definition from the source you're getting it from (if applicable) before resorting to detection.

Here is another solution to change the location using href and clear the hash without scrolling.

The magic solution is explained here. Specs here.

const hash = window.location.hash;
history.scrollRestoration = 'manual';
window.location.href = hash;    
history.pushState('', document.title, window.location.pathname);

excerpt from working code (without error handling):

var SubItemModel = mongoose.model('subitems', SubItemSchema);
var ItemModel    = mongoose.model('items', ItemSchema);

var new_sub_item_model = new SubItemModel(new_sub_item_plain);
new_sub_item_model.save(function (error, new_sub_item) {

  var new_item = new ItemModel(new_item);
  new_item.subitem = new_sub_item._id;
  new_item.save(function (error, new_item) {
    // so this is a valid way to populate via the Model
    // as documented in comments above (here @stack overflow):
    ItemModel.populate(new_item, { path: 'subitem', model: 'subitems' }, function(error, new_item) {
      callback(new_item.toObject());
    });
    // or populate directly on the result object
    new_item.populate('subitem', function(error, new_item) {
      callback(new_item.toObject());
    });
  });

});

If you want to enable CORS for all routes, then just install flask_cors extension (pip3 install -U flask_cors) and wrap app like this: CORS(app).

That is enough to do it (I tested this with a POST request to upload an image, and it worked for me):

from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app) # This will enable CORS for all routes

Important note: if there is an error in your route, let us say you try to print a variable that does not exist, you will get a CORS error related message which, in fact, has nothing to do with CORS.

since iOS7 use

self.automaticallyAdjustsScrollViewInsets = NO;

//and create you page scroller with 3 pages

    self.pageView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    [self.pageView setContentSize:CGSizeMake(self.view.frame.size.width*3, self.view.frame.size.height)];
    [self.pageView setShowsVerticalScrollIndicator:NO];
    [self.pageView setPagingEnabled:YES];
    [self.view addSubview:self.pageView];

Where clause and args work together to form the WHERE statement of the SQL query. So say you looking to express

WHERE Column1 = 'value1' AND Column2 = 'value2'

Then your whereClause and whereArgs will be as follows

String whereClause = "Column1 =? AND Column2 =?";
String[] whereArgs = new String[]{"value1", "value2"};

If you want to select all table columns, i believe a null string passed to tableColumns will suffice.

As you say, the % sign is used to take the modulus (division remainder).

In w3schools' JavaScript Arithmetic page we can read in the Remainder section what I think to be a great explanation

In arithmetic, the division of two integers produces a quotient and a remainder.

In mathematics, the result of a modulo operation is the remainder of an arithmetic division.

So, in your specific case, when you try to divide 7 bananas into a group of 5 bananas, you're able to create 1 group of 5 (quotient) and you'll be left with 2 bananas (remainder).

If 5 bananas into a group of 7, you won't be able to and so you're left with again the 5 bananas (remainder).

SVG has properties width and height. They return an object SVGAnimatedLength with two properties: animVal and baseVal. This interface is used for animation, where baseVal is the value before animation. From what I can see, this method returns consistent values in both Chrome and Firefox, so I think it can also be used to get calculated size of SVG.

If you want to check if an object is within in array by checking an attribute on the object, you can use any? and pass a block that evaluates to true or false:

unless @suggested_horses.any? {|h| h.id == horse.id }
  @suggested_horses << horse
end

The approach I use is this:

$('a').on('click', function(event){
    if (yourCondition === true) { //Put here the condition you want
        event.preventDefault(); // Here triggering stops
        // Here you can put code relevant when event stops;
        return;
    }
    // Here your event works as expected and continue triggering
    // Here you can put code you want before triggering
});

Math.ceil() is the correct function to call. I'm guessing a is an int, which would make a / 100 perform integer arithmetic. Try Math.ceil(a / 100.0) instead.

int a = 142;
System.out.println(a / 100);
System.out.println(Math.ceil(a / 100));
System.out.println(a / 100.0);
System.out.println(Math.ceil(a / 100.0));
System.out.println((int) Math.ceil(a / 100.0));

Outputs:

1
1.0
1.42
2.0
2

All user installed apks are located in /data/app/, but you can only access this if you are rooted(afaik, you can try without root and if it doesn't work, rooting isn't hard. I suggest you search xda-developers for rooting instructions)

Use Root explorer or ES File Explorer to access /data/app/ (you have to keep going "up" until you reach the root directory /, kind of like C: in windows, before you can see the data directory(folder)). In ES file explorer you must also tick a checkbox in settings to allow going up to the root directory.

When you are in there you will see all your applications apks, though they might be named strangely. Just copy the wanted .apk and paste in the sd card, after that you can copy it to your computer and when you want to install it just open the .apk in a file manager (be sure to have install from unknown sources enabled in android settings). Even if you only want to send over bluetooth I would recommend copying it to the SD first.

PS Note that paid apps probably won't work being copied this way, since they usually check their licence online. PPS Installing an app this way may not link it with google play(you won't see it in my apps and it won't get updates).

If you wanted to get more than just the mean (aka average) you might check out scipy stats

from scipy import stats
l = [15, 18, 2, 36, 12, 78, 5, 6, 9]
print(stats.describe(l))

# DescribeResult(nobs=9, minmax=(2, 78), mean=20.11111111111111, 
# variance=572.3611111111111, skewness=1.7791785448425341, 
# kurtosis=1.9422716419666397)

Here is Java 8 solution

public static boolean contains(final int[] arr, final int key) {
    return Arrays.stream(arr).anyMatch(i -> i == key);
}

I use an i5 processor with 4Gb RAM. It works very well. I feel this is the minimum configuration required to run both eclipse and android avd simultaneously. Just an old processor with high RAM is not sufficient.

Perform the following steps:

1. Start the Registry Editor by typing regedit in the Run window.
2. Select the following key in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC.
3. In the Security menu, click Permissions.
4. Grant Full Permission to the account which is being used for making connections.
5. Quit the Registry Editor.

You can use InlineComparer

public class InlineComparer<T> : IEqualityComparer<T>
{
    //private readonly Func<T, T, bool> equalsMethod;
    //private readonly Func<T, int> getHashCodeMethod;
    public Func<T, T, bool> EqualsMethod { get; private set; }
    public Func<T, int> GetHashCodeMethod { get; private set; }

    public InlineComparer(Func<T, T, bool> equals, Func<T, int> hashCode)
    {
        if (equals == null) throw new ArgumentNullException("equals", "Equals parameter is required for all InlineComparer instances");
        EqualsMethod = equals;
        GetHashCodeMethod = hashCode;
    }

    public bool Equals(T x, T y)
    {
        return EqualsMethod(x, y);
    }

    public int GetHashCode(T obj)
    {
        if (GetHashCodeMethod == null) return obj.GetHashCode();
        return GetHashCodeMethod(obj);
    }
}

Usage sample:

  var comparer = new InlineComparer<DetalleLog>((i1, i2) => i1.PeticionEV == i2.PeticionEV && i1.Etiqueta == i2.Etiqueta, i => i.PeticionEV.GetHashCode() + i.Etiqueta.GetHashCode());
  var peticionesEV = listaLogs.Distinct(comparer).ToList();
  Assert.IsNotNull(peticionesEV);
  Assert.AreNotEqual(0, peticionesEV.Count);

Using IEqualityComparer for Union
Can I specify my explicit type comparator inline?

Although this question isn't quite new and an answer was already chosen, I would like to share another nice approach.

Using the paramiko library - a pure python implementation of SSH2 - your python script can connect to a remote host via SSH, copy itself (!) to that host and then execute that copy on the remote host. Stdin, stdout and stderr of the remote process will be available on your local running script. So this solution is pretty much independent of an IDE.

On my local machine, I run the script with a cmd-line parameter 'deploy', which triggers the remote execution. Without such a parameter, the actual code intended for the remote host is run.

import sys
import os

def main():
    print os.name

if __name__ == '__main__':
    try:
        if sys.argv[1] == 'deploy':
            import paramiko

            # Connect to remote host
            client = paramiko.SSHClient()
            client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
            client.connect('remote_hostname_or_IP', username='john', password='secret')

            # Setup sftp connection and transmit this script
            sftp = client.open_sftp()
            sftp.put(__file__, '/tmp/myscript.py')
            sftp.close()

            # Run the transmitted script remotely without args and show its output.
            # SSHClient.exec_command() returns the tuple (stdin,stdout,stderr)
            stdout = client.exec_command('python /tmp/myscript.py')[1]
            for line in stdout:
                # Process each line in the remote output
                print line

            client.close()
            sys.exit(0)
    except IndexError:
        pass

    # No cmd-line args provided, run script normally
    main()

Exception handling is left out to simplify this example. In projects with multiple script files you will probably have to put all those files (and other dependencies) on the remote host.

Quick note: if you're also using coord_flip() to flip the x and the y axis, you won't be able to set range limits using coord_cartesian() because those two functions are exclusive (see here).

Fortunately, this is an easy fix; set your limits within coord_flip() like so:

p + coord_flip(ylim = c(3,5), xlim = c(100, 400))

This just alters the visible range (i.e. doesn't remove data points).

Here you go:

<?php

$html = '<p style="border: 1px solid red;">Test</p>';
echo preg_replace('/<p style="(.+?)">(.+?)<\/p>/i', "<p>$2</p>", $html);

?>

By the way, as pointed out by others, regex are not suggested for this.

Deprecated in general means "don't use it".
A deprecated function may or may not work, but it is not guaranteed to work.

Here's a quick way to do it, won't require anything besides sys.. though functionality is limited:

flag = "--flag" in sys.argv[1:]

[1:] is in case if the full file name is --flag

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

Depending on what style attributes you'd like to change you may be able to use the Paris library:

Button view = (Button) LayoutInflater.from(this).inflate(R.layout.section_button, null);
Paris.style(view).apply(R.style.YourStyle);

Many attributes like background, padding, textSize, textColor, etc. are supported.

• List of currently supported attributes
• Installation instructions

Disclaimer: I authored the library.

2) git add .

3) git commit -m "Add all my files"

4) git remote add origin https://github.com/yourusername/your-repo-name.git

Upload of project from scratch require git pull origin master.

5) git pull origin master

6) git push origin master

If any problem occurs in pushing use git push --force origin master

The solution that worked for me is:

• use suptitle() for the actual title
• use title() for the subtitle and adjust it using the optional parameter y:

    import matplotlib.pyplot as plt
    """
            some code here
    """
    plt.title('My subtitle',fontsize=16)
    plt.suptitle('My title',fontsize=24, y=1)
    plt.show()

There can be some nasty overlap between the two pieces of text. You can fix this by fiddling with the value of y until you get it right.

I spent time finding a proper way. This may be useful for others.

Create a UDF and refer in the query -

http://www.geekzilla.co.uk/view5C09B52C-4600-4B66-9DD7-DCE840D64CBD.htm

Install the NuGet package called SevenZipSharp.Interop

Then:

SevenZipBase.SetLibraryPath(@".\x86\7z.dll");
var compressor = new SevenZip.SevenZipCompressor();
var filesToCompress = Directory.GetFiles(@"D:\data\");
compressor.CompressFiles(@"C:\archive\abc.7z", filesToCompress);

This problem is caused (as others have stated) by model attributes being persisted into the query string - this is usually undesirable and is at risk of creating security holes as well as ridiculous query strings. My usual solution is to never use Strings for redirects in Spring MVC, instead use a RedirectView which can be configured not to expose model attributes (see: http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/web/servlet/view/RedirectView.html)

RedirectView(String url, boolean contextRelative, boolean http10Compatible, boolean exposeModelAttributes)

So I tend to have a util method which does a 'safe redirect' like:

public static RedirectView safeRedirect(String url) {
    RedirectView rv = new RedirectView(url);
    rv.setExposeModelAttributes(false);
    return rv;
}

The other option is to use bean configuration XML:

<bean id="myBean" class="org.springframework.web.servlet.view.RedirectView">
   <property name="exposeModelAttributes" value="false" />
   <property name="url" value="/myRedirect"/>
</bean>

Again, you could abstract this into its own class to avoid repetition (e.g. SafeRedirectView).

A note about 'clearing the model' - this is not the same as 'not exposing the model' in all circumstances. One site I worked on had a lot of filters which added things to the model, this meant that clearing the model before redirecting would not prevent a long query string. I would also suggest that 'not exposing model attributes' is a more semantic approach than 'clearing the model before redirecting'.

Check out this article and this simple example. Quick translation of same to your classes ...

var d1 = typeof(Task<>);
Type[] typeArgs = { typeof(Item) };
var makeme = d1.MakeGenericType(typeArgs);
object o = Activator.CreateInstance(makeme);

Per your edit: For that case, you can do this ...

var d1 = Type.GetType("GenericTest.TaskA`1"); // GenericTest was my namespace, add yours
Type[] typeArgs = { typeof(Item) };
var makeme = d1.MakeGenericType(typeArgs);
object o = Activator.CreateInstance(makeme);

To see where I came up with backtick1 for the name of the generic class, see this article.

Note: if your generic class accepts multiple types, you must include the commas when you omit the type names, for example:

Type type = typeof(IReadOnlyDictionary<,>);

I was debugging an issue with git and needed some very verbose output to figure out what was going wrong. I ended up setting the GIT_TRACE environment variable:

export GIT_TRACE=1
git add *.txt

You can also use these on the same line:

GIT_TRACE=1 git add *.txt

Output:

The above answers do not fully answer the question (specifically the millisec part). My solution to this is to use gettimeofday before strftime. Note the care to avoid rounding millisec to "1000". This is based on Hamid Nazari's answer.

#include <stdio.h>
#include <sys/time.h>
#include <time.h>
#include <math.h>

int main() {
  char buffer[26];
  int millisec;
  struct tm* tm_info;
  struct timeval tv;

  gettimeofday(&tv, NULL);

  millisec = lrint(tv.tv_usec/1000.0); // Round to nearest millisec
  if (millisec>=1000) { // Allow for rounding up to nearest second
    millisec -=1000;
    tv.tv_sec++;
  }

  tm_info = localtime(&tv.tv_sec);

  strftime(buffer, 26, "%Y:%m:%d %H:%M:%S", tm_info);
  printf("%s.%03d\n", buffer, millisec);

  return 0;
}

The logical OR '||' automatically short circuits if it meets a true condition once.

false || false || true || false = true, stops at second condition.

On the other hand, the logical AND '&&' automatically short circuits if it meets a false condition once.

false && true && true && true = false, stops at first condition.

Multi cursor edit is natively supported in Visual Studio starting from version 2017 Update 8. The following is an extract of the documentation:

• Ctrl + Alt + click : Add a secondary caret
• Ctrl + Alt + double-click : Add a secondary word selection
• Ctrl + Alt + click + drag : Add a secondary selection
• Shift + Alt + . : Add the next matching text as a selection
• Shift + Alt + ; : Add all matching text as selections
• Shift + Alt + , : Remove last selected occurrence
• Shift + Alt + / : Skip next matching occurrence
• Alt + click : Add a box selection
• Esc or click : Clear all selections

Some of those commands are also available in the Edit menu:

Strip out tags, leave only alphanumeric characters and space:

Edit: all credit to DaveRandom for the perfect solution...

$clear = preg_replace('/[^a-zA-Z0-9\s]/', '', strip_tags(html_entity_decode($des)));

I found a solution, which at least helps in my situation, it probably is not suitable for other situations:

I give all my green child divs a complete margin:

margin: 10px;

And for the surrounding yellow parent div i set a negative margin:

margin: -10px;

I also had to remove any explicit width or height setting for the yellow parent div, otherwise it did not work.

This way, in absolute terms, the child divs are correctly aligned, although the parent yellow div obviously is set off, which in my case is OK, because it will not be visible.

To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:

  3  
  4    PROCEDURE pp (inp p_type);

  4      FOR i IN 1..inp.count LOOP
  5        dbms_output.put_line(inp(i));
  6      END LOOP;
  7    END pp;
  8  END p;
  9  /

Package body created
SQL> DECLARE
  2    v_t p.p_type;
  3  BEGIN
  4    v_t(1) := 'this is a test of p';
  5    v_t(2) := 'A second test line for p';
  6    p.pp(v_t);
  7  END;
  8  /

this is a test of p
A second test line for p

This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.

I recommend: Twisted (http://twistedmatrix.com)

an event-driven networking engine written in Python and licensed under the open source MIT license.

It's cross-platform and was preinstalled on OS X 10.5 to 10.12. Amongst other things you can start up a simple web server in the current directory with:

twistd -no web --path=.

Details

Explanation of Options (see twistd --help for more):

-n, --nodaemon       don't daemonize, don't use default umask of 0077
-o, --no_save        do not save state on shutdown

"web" is a Command that runs a simple web server on top of the Twisted async engine. It also accepts command line options (after the "web" command - see twistd web --help for more):

  --path=             <path> is either a specific file or a directory to be
                      set as the root of the web server. Use this if you
                      have a directory full of HTML, cgi, php3, epy, or rpy
                      files or any other files that you want to be served up
                      raw.

There are also a bunch of other commands such as:

conch            A Conch SSH service.
dns              A domain name server.
ftp              An FTP server.
inetd            An inetd(8) replacement.
mail             An email service
... etc

Installation

Ubuntu

sudo apt-get install python-twisted-web (or python-twisted for the full engine)

Mac OS-X (comes preinstalled on 10.5 - 10.12, or is available in MacPorts and through Pip)

sudo port install py-twisted

Windows

installer available for download at http://twistedmatrix.com/

HTTPS

Twisted can also utilise security certificates to encrypt the connection. Use this with your existing --path and --port (for plain HTTP) options.

twistd -no web -c cert.pem -k privkey.pem --https=4433

dangerouslySetInnerHTML

dangerouslySetInnerHTML is React’s replacement for using innerHTML in the browser DOM. In general, setting HTML from code is risky because it’s easy to inadvertently expose your users to a cross-site scripting (XSS) attack. So, you can set HTML directly from React, but you have to type out dangerouslySetInnerHTML and pass an object with a __html key, to remind yourself that it’s dangerous. For example:

function createMarkup() {
  return {__html: 'First · Second'};
}

function MyComponent() {
  return <div dangerouslySetInnerHTML={createMarkup()} />;
}

as i understood it so you won't think the value in memory is changed. in c when you do x++ the value of x in memory changes. but in python all numbers are immutable hence the address that x pointed as still has x not x+1. when you write x++ you would think that x change what really happens is that x refrence is changed to a location in memory where x+1 is stored or recreate this location if doe's not exists.

You can't have two elements with the same ID.

Aside from that, you are defining them as block elemnts, meaning (in layman's terms) that they are being forced to appear on their own line.

Instead, try something like this:

<div class="link"><a href="..."><img src="..."... /></a></div>
<div class="link"><a href="..."><img src="..."... /></a></div>

CSS:

.link {
    width: 50%;
    float: left;
    text-align: center;
}

This is an old question, that unfortunately even several years on doesn't have a good solution. I've just ported an app from iOS (Obj C) to Android. The biggest problem was not the back end code (for many/most folks, if you can code in Obj C you can code in Java) but porting the native interfaces. What Todd said above, UI layout is still a complete pain. In my experience, the fastest wat to develop a reliable UI that supports multiple formats etc is in good 'ol HTML.

Guessing that what you want to do, is call Files.lines(...) on a resource that comes from the classpath - possibly from within a jar.

Since Oracle convoluted the notion of when a Path is a Path by not making getResource return a usable path if it resides in a jar file, what you need to do is something like this:

Stream<String> stream = new BufferedReader(new InputStreamReader(ClassLoader.getSystemResourceAsStream("/filename.txt"))).lines();

Agree no matches in your example.
If you mean both columns on either then need a query like this or need to re-examine the data design.

    Select TableA.Col1, TableA.Col2, TableB.Val
    FROM TableA
    INNER JOIN TableB
          ON TableA.Col1 = TableB.Col1 OR TableA.Col2 = TableB.Col2 
          OR TableA.Col2 = TableB.Col1 OR TableA.Col1 = TableB.Col2

This is a hack to make inner functions (functions defined inside other functions) work more like they should. In javascript when you define one function inside another this automatically gets set to the global scope. This can be confusing because you expect this to have the same value as in the outer function.

var car = {};
car.starter = {};

car.start = function(){
    var that = this;

    // you can access car.starter inside this method with 'this'
    this.starter.active = false;

    var activateStarter = function(){
        // 'this' now points to the global scope
        // 'this.starter' is undefined, so we use 'that' instead.
        that.starter.active = true;

        // you could also use car.starter, but using 'that' gives
        // us more consistency and flexibility
    };

    activateStarter();

};

This is specifically a problem when you create a function as a method of an object (like car.start in the example) then create a function inside that method (like activateStarter). In the top level method this points to the object it is a method of (in this case, car) but in the inner function this now points to the global scope. This is a pain.

Creating a variable to use by convention in both scopes is a solution for this very general problem with javascript (though it's useful in jquery functions, too). This is why the very general sounding name that is used. It's an easily recognizable convention for overcoming a shortcoming in the language.

Like El Ronnoco hints at Douglas Crockford thinks this is a good idea.

you can do it like this:

map(list, df.values)

Much like the manual, use an equals (=) sign in your definition of the parameters:

function dosomething($var1, $var2, $var3 = 'somevalue'){
    // Rest of function here...
}

Try this solution:

Oz<-subset(data, data$Month==5,select=Ozone) # select ozone  value in the month of                 
                                             #May (i.e. Month = 5)
summary(T)                                   #gives caracteristics of table( contains 1 column of Ozone) including max, min ...

You could put it in the session:

session_start();
$_SESSION['array_name'] = $array_name;

Or if you want to send it via a form you can serialize it:

<input type='hidden' name='input_name' value="<?php echo htmlentities(serialize($array_name)); ?>" />

$passed_array = unserialize($_POST['input_name']);

Note that to work with serialized arrays, you need to use POST as the form's transmission method, as GET has a size limit somewhere around 1024 characters.

I'd use sessions wherever possible.

You don't have to do this locally either. You can do it through a remote repository, for example:

svn export http://<repo>/process/test.txt /path/to/code/

Building on the accepted answer, this will work with ngRepeat, filterand handle expections better:

Controller:

vm.remove = function(item, array) {
  var index = array.indexOf(item);
  if(index>=0)
    array.splice(index, 1);
}

View:

ng-click="vm.remove(item,$scope.bdays)"

This issue has driven me mad: Spring is such a potent tool and yet, such a simple thing as writing an output String as JSON seems impossible without ugly hacks.

My solution (in Kotlin) that I find the least intrusive and most transparent is to use a controller advice and check whether the request went to a particular set of endpoints (REST API typically since we most often want to return ALL answers from here as JSON and not make specializations in the frontend based on whether the returned data is a plain string ("Don't do JSON deserialization!") or something else ("Do JSON deserialization!")). The positive aspect of this is that the controller remains the same and without hacks.

The supports method makes sure that all requests that were handled by the StringHttpMessageConverter(e.g. the converter that handles the output of all controllers that return plain strings) are processed and in the beforeBodyWrite method, we control in which cases we want to interrupt and convert the output to JSON (and modify headers accordingly).

@ControllerAdvice
class StringToJsonAdvice(val ob: ObjectMapper) : ResponseBodyAdvice<Any?> {
    
    override fun supports(returnType: MethodParameter, converterType: Class<out HttpMessageConverter<*>>): Boolean =
        converterType === StringHttpMessageConverter::class.java

    override fun beforeBodyWrite(
        body: Any?,
        returnType: MethodParameter,
        selectedContentType: MediaType,
        selectedConverterType: Class<out HttpMessageConverter<*>>,
        request: ServerHttpRequest,
        response: ServerHttpResponse
    ): Any? {
        return if (request.uri.path.contains("api")) {
            response.getHeaders().contentType = MediaType.APPLICATION_JSON
            ob.writeValueAsString(body)
        } else body
    }
}

I hope in the future that we will get a simple annotation in which we can override which HttpMessageConverter should be used for the output.

If you get this error when you try to pipe/redirect output of your script

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-5: ordinal not in range(128)

Just export PYTHONIOENCODING in console and then run your code.

export PYTHONIOENCODING=utf8

To hide the grid column

jQuery("#validGrid").jqGrid('hideCol',str);

public string RemoveSpecial(string evalstr)
{
StringBuilder finalstr = new StringBuilder();
            foreach(char c in evalstr){
            int charassci = Convert.ToInt16(c);
            if (!(charassci >= 33 && charassci <= 47))// special char ???
             finalstr.append(c);
            }
return finalstr.ToString();
}

ddList.Items.FindByText("oldValue").Selected = false;
ddList.Items.FindByText("newValue").Selected = true;

Ignacio Vazquez-Abrams is correct. But to elaborate, re.match() will return either None, which evaluates to False, or a match object, which will always be True as he said. Only if you want information about the part(s) that matched your regular expression do you need to check out the contents of the match object.

After my previous answer disaster, I'm going to try something else.

List<Model> usrList  = 
(list.Where(n => n.application == "applicationame").ToList());
usrList.ForEach(n => n.users.RemoveAll(n => n.surname != "surname"));

To illustrate what the other answers are saying:

$ foo="Hello, World"
$ echo $foo
Hello, World
$ bar="Goodbye"
$ export foo
$ bash
bash-3.2$ echo $foo
Hello, World
bash-3.2$ echo $bar

bash-3.2$ 

My understanding after reading the link offered by G.Grothendieck is that %>% is an operator that pipes functions. This helps readability and productivity as it's easier to follow the flow of multiple functions through these pipes than going backwards when multiple function are nested.

Not sure what you are really after but if you want to print exactly what you have you can do:

Option 1

print(df['Item'].to_csv(index=False))

Sweet
Candy
Chocolate

Option 2

for v in df['Item']:
    print(v)

Sweet
Candy
Chocolate

The Pattern.quote(String s) sort of does what you want. However it leaves a little left to be desired; it doesn't actually escape the individual characters, just wraps the string with \Q...\E.

There is not a method that does exactly what you are looking for, but the good news is that it is actually fairly simple to escape all of the special characters in a Java regular expression:

regex.replaceAll("[\\W]", "\\\\$0")

Why does this work? Well, the documentation for Pattern specifically says that its permissible to escape non-alphabetic characters that don't necessarily have to be escaped:

It is an error to use a backslash prior to any alphabetic character that does not denote an escaped construct; these are reserved for future extensions to the regular-expression language. A backslash may be used prior to a non-alphabetic character regardless of whether that character is part of an unescaped construct.

For example, ; is not a special character in a regular expression. However, if you escape it, Pattern will still interpret \; as ;. Here are a few more examples:

• > becomes \> which is equivalent to >
• [ becomes \[ which is the escaped form of [
• 8 is still 8.
• \) becomes \\\) which is the escaped forms of \ and ( concatenated.

Note: The key is is the definition of "non-alphabetic", which in the documentation really means "non-word" characters, or characters outside the character set [a-zA-Z_0-9].

Oracle doesn't provide such IIF Function. Instead, try using one of the following alternatives:

DECODE Function:

SELECT DECODE(EMP_ID, 1, 'True', 'False') from Employee

CASE Function:

SELECT CASE WHEN EMP_ID = 1 THEN 'True' ELSE 'False' END from Employee

I tried most of the other answers on this question here and came to find that most of the services used were defunct except one.

Here is a script that should do the trick and download only a minimal amount of information:

#!/usr/bin/env python

import urllib
import re

def get_external_ip():
    site = urllib.urlopen("http://checkip.dyndns.org/").read()
    grab = re.findall('([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)', site)
    address = grab[0]
    return address

if __name__ == '__main__':
  print( get_external_ip() )

You can redirect by this method also:

return Yii::$app->response->redirect(['user/index', 'id' => 10]);

If you want to send the Header information immediately use with send().This method adds a Location header to the current response.

return Yii::$app->response->redirect(['user/index', 'id' => 10])->send();

If you want the complete URL then use like Url::to(['user/index', 'id' => 302]) with the header of use yii\helpers\Url;.

For more information check Here. Hope this will help someone.

If you mean that you have an environment variable named CLASSPATH, I'd say that's your mistake. I don't have such a thing on any machine with which I develop Java. CLASSPATH is so tied to a particular project that it's impossible to have a single, correct CLASSPATH that works for all.

I set CLASSPATH for each project using either an IDE or Ant. I do a lot of web development, so each WAR and EAR uses their own CLASSPATH.

It's ignored by IDEs and app servers. Why do you have it? I'd recommend deleting it.

The comparator should be only for the key, not for the whole entry. It sorts the entries based on the keys.

You should change it to something as follows

SortedMap<String, Double> myMap = 
    new TreeMap<String, Double>(new Comparator<String>()
    {
        public int compare(String o1, String o2)
        {
            return o1.compareTo(o2);
        } 
});

Update

You can do something as follows (create a list of entries in the map and sort the list base on value, but note this not going to sort the map itself) -

List<Map.Entry<String, Double>> entryList = new ArrayList<Map.Entry<String, Double>>(myMap.entrySet());
    Collections.sort(entryList, new Comparator<Map.Entry<String, Double>>() {
        @Override
        public int compare(Entry<String, Double> o1, Entry<String, Double> o2) {
            return o1.getValue().compareTo(o2.getValue());
        }
    });

Have you tried Advanced Filter? Using your short list as the 'Criteria' and long list as the 'List Range'. Use the options: 'Filter in Place' and 'Unique Values'.

You should be presented with the list of unique values that only appear in your short list.

Alternatively, you can paste your Unique list to another location (on the same sheet), if you prefer. Choose the option 'Copy to another Location' and in the 'Copy to' box enter the cell reference (say F1) where you want the Unique list.

Note: this will work with the two columns (name/ID) too, if you select the two columns as both 'Criteria' and 'List Range'.

Java doesn't have an analog to C++'s structs, but you can use classes with all public members.

Here is how I was able to trick Excel to count expired certifications in a list. I didn't have a set date, or date range, just current date. "TODAY()" doesn't work in these for Excel 2013. It sees it as text or condition, not the date value. So these previous didn't work for me. So the word problem/scenario: How many people are expired in this list?

Use: =IFERROR(D5-TODAY(),0) Where D5 is the date to be interrogated.

Then use: =IF(J5>=1,1,0) Where J5 is the cell where the first equation is producing either a positive or negative number. This set, I have hidden on the side of the visible sheet, then I just sum the total for the number of unexpired members.

usermod -m -d /newhome username

This problem happened for me only in special cases, when I called website from some internet providers,

I've configured only ip v4 in VirtualHost configuration of apache, but some of router use ip v6, and when I added ip v6 to apache config the problem solved.

"Easiest way is to use the built-in feature of SQL Management Studio" but... I have resolved it with a function and a couple of procedures. For example, to obtain the create table for a table named 'table_name', you have to execute just the procedure called sp_ppinScriptTabla:

Exec sp_ppinScriptTabla 'table_name'

I was facing this error because

Sometimes when I Combine the path with File Name and FileName = ""

It become Path Directory not a file which is a problem as mentioned above

so you must check for FileName like this

if(itemUri!="")
        File.Delete(Path.Combine(RemoteDirectoryPath, itemUri));

I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.

You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.

Edit:

Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.

For instance:

public ActionResult Index()
{
    return View();
}

[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
   // load object and return in view
   ViewModel viewModel = Load(id);

   // get the previous url and store it with view model
   viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;

   return View(viewModel);
}

[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
   // Attempt to save the posted object if it works, return index if not return the Edit view again

   bool success = Save(viewModel);
   if (success)
   {
       return Redirect(viewModel.PreviousUrl);
   }
   else
   {
      ModelState.AddModelError("There was an error");
      return View(viewModel);
   }
}

The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:

@model ViewModel

@using (Html.BeginForm())
{
    ...
    <input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}

Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.

This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.

Maybe you should look into using something simple like a truecrypt volume for source code storage as that seems to be a concern of yours. You can create an encrypted file on a usb key or just encrypt the whole volume (provided the code will fit) so you can simply take the key with you at the end of the day.

To compile, you could then use something like PyInstaller or py2exe in order to create a stand-alone executable. If you really wanted to go the extra mile, look into a packer or compression utility in order to add more obfuscation. If none of these are an option, you could at least compile the script into bytecode so it isn't immediately readable. Keep in mind that these methods will merely slow someone trying to debug or decompile your program.

Django also has the 'latest(field_name = None)' function that finds the latest (max. value) entry. It not only works with date fields but also with strings and integers.

You can give the field name when calling that function:

max_rated_entry = YourModel.objects.latest('rating')
return max_rated_entry.details

Or you can already give that field name in your models meta data:

from django.db import models

class YourModel(models.Model):
    #your class definition
    class Meta:
        get_latest_by = 'rating'

Now you can call 'latest()' without any parameters:

max_rated_entry = YourModel.objects.latest()
return max_rated_entry.details

<script type="text/javascript" src="jquery-1.9.1.min.js"></script>

            $(this).next(".hidden-content").slideToggle("slow");
            $(this).toggleClass("expanded-header");
        });
    });
</script>

You don't really need a specific client, it's fairly simple with most libraries. For example in jQuery you can just call the generic $.ajax function with the type of request you want to make:

$.ajax({
    url: 'http://example.com/',
    type: 'PUT',
    data: 'ID=1&Name=John&Age=10', // or $('#myform').serializeArray()
    success: function() { alert('PUT completed'); }
});

You can replace PUT with GET/POST/DELETE or whatever.

From Python 2.5 onwards, you can use

from ..Modules import LDAPManager

The leading period takes you "up" a level in your heirarchy.

See the Python docs on intra-package references for imports.

I could be crazy but I'm finding these answers seriously bloated. Here's my solution

function serialiseForm(form) {
  var input = form.getElementsByTagName("input");
  var formData = {};
  for (var i = 0; i < input.length; i++) {
    formData[input[i].name] = input[i].value;
  }
  return formData = JSON.stringify(formData);
}

Install PAR::Packer from CPAN (it is free) and use pp utility.

Here is an easier way you can write the time format (hh:mm:ss tt) and display them separately if you wish.

string time = DateTime.Now.Hour.ToString("00") + ":" + DateTime.Now.Minute.ToString("00") + ":" + DateTime.Now.Second.ToString("00") + DateTime.Now.ToString(" tt");

or just simply:

 DateTime.Now.ToString("hh:mm:ss tt")

Even in spite of being final a field can be modified outside of static initializer and (at least JVM HotSpot) will execute the bytecode perfectly fine.

The problem is that Java compiler does not allow this, but this can be easily bypassed using objectweb.asm. Here is p?e?r?f?e?c?t?l?y? ?v?a?l?i?d? ?c?l?a?s?s?f?i?l?e? an invalid classfile from the JVMS specification standpoint, but it passes bytecode verification and then is successfully loaded and initialized under JVM HotSpot OpenJDK12:

ClassWriter cw = new ClassWriter(0);
cw.visit(Opcodes.V1_8, Opcodes.ACC_PUBLIC, "Cl", null, "java/lang/Object", null);
{
    FieldVisitor fv = cw.visitField(Opcodes.ACC_PRIVATE | Opcodes.ACC_STATIC | Opcodes.ACC_FINAL, "fld", "I", null, null);
    fv.visitEnd();
}
{
    // public void setFinalField1() { //... }
    MethodVisitor mv = cw.visitMethod(Opcodes.ACC_PUBLIC | Opcodes.ACC_STATIC, "setFinalField1", "()V", null, null);
    mv.visitMaxs(2, 1);
    mv.visitInsn(Opcodes.ICONST_5);
    mv.visitFieldInsn(Opcodes.PUTSTATIC, "Cl", "fld", "I");
    mv.visitInsn(Opcodes.RETURN);
    mv.visitEnd();
}
{
    // public void setFinalField2() { //... }
    MethodVisitor mv = cw.visitMethod(Opcodes.ACC_PUBLIC | Opcodes.ACC_STATIC, "setFinalField2", "()V", null, null);
    mv.visitMaxs(2, 1);
    mv.visitInsn(Opcodes.ICONST_2);
    mv.visitFieldInsn(Opcodes.PUTSTATIC, "Cl", "fld", "I");
    mv.visitInsn(Opcodes.RETURN);
    mv.visitEnd();
}
cw.visitEnd();

In Java, the class looks roughly speaking as follows:

public class Cl{
    private static final int fld;

    public static void setFinalField1(){
        fld = 5;
    }

    public static void setFinalField2(){
        fld = 2;
    }
}

which cannot be compiled with javac, but can be loaded and executed by JVM.

JVM HotSpot has special treatment of such classes in the sense that it prevents such "constants" from participating in constant folding. This check is done on the bytecode rewriting phase of class initialization:

// Check if any final field of the class given as parameter is modified
// outside of initializer methods of the class. Fields that are modified
// are marked with a flag. For marked fields, the compilers do not perform
// constant folding (as the field can be changed after initialization).
//
// The check is performed after verification and only if verification has
// succeeded. Therefore, the class is guaranteed to be well-formed.
InstanceKlass* klass = method->method_holder();
u2 bc_index = Bytes::get_Java_u2(bcp + prefix_length + 1);
constantPoolHandle cp(method->constants());
Symbol* ref_class_name = cp->klass_name_at(cp->klass_ref_index_at(bc_index));
if (klass->name() == ref_class_name) {
   Symbol* field_name = cp->name_ref_at(bc_index);
   Symbol* field_sig = cp->signature_ref_at(bc_index);

   fieldDescriptor fd;
   if (klass->find_field(field_name, field_sig, &fd) != NULL) {
      if (fd.access_flags().is_final()) {
         if (fd.access_flags().is_static()) {
            if (!method->is_static_initializer()) {
               fd.set_has_initialized_final_update(true);
            }
          } else {
            if (!method->is_object_initializer()) {
              fd.set_has_initialized_final_update(true);
            }
          }
        }
      }
    }
}

The only restriction that JVM HotSpot checks is that the final field should not be modified outside of the class that the final field is declared at.

Include the HTML

Including HTML is done by using a w3-include-html attribute:

Example

    <div w3-include-html="content.html"></div>

Add the JavaScript

HTML includes are done by JavaScript.

    <script>
    function includeHTML() {
      var z, i, elmnt, file, xhttp;
      /*loop through a collection of all HTML elements:*/
      z = document.getElementsByTagName("*");
      for (i = 0; i < z.length; i++) {
        elmnt = z[i];
        /*search for elements with a certain atrribute:*/
        file = elmnt.getAttribute("w3-include-html");
        if (file) {
          /*make an HTTP request using the attribute value as the file name:*/
          xhttp = new XMLHttpRequest();
          xhttp.onreadystatechange = function() {
            if (this.readyState == 4) {
              if (this.status == 200) {elmnt.innerHTML = this.responseText;}
              if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
              /*remove the attribute, and call this function once more:*/
              elmnt.removeAttribute("w3-include-html");
              includeHTML();
            }
          } 
          xhttp.open("GET", file, true);
          xhttp.send();
          /*exit the function:*/
          return;
        }
      }
    }
    </script>

Call includeHTML() at the bottom of the page:

Example

<!DOCTYPE html>
<html>
<script>
function includeHTML() {
  var z, i, elmnt, file, xhttp;
  /*loop through a collection of all HTML elements:*/
  z = document.getElementsByTagName("*");
  for (i = 0; i < z.length; i++) {
    elmnt = z[i];
    /*search for elements with a certain atrribute:*/
    file = elmnt.getAttribute("w3-include-html");
    if (file) {
      /*make an HTTP request using the attribute value as the file name:*/
      xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
        if (this.readyState == 4) {
          if (this.status == 200) {elmnt.innerHTML = this.responseText;}
          if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
          /*remove the attribute, and call this function once more:*/
          elmnt.removeAttribute("w3-include-html");
          includeHTML();
        }
      }      
      xhttp.open("GET", file, true);
      xhttp.send();
      /*exit the function:*/
      return;
    }
  }
};
</script>
<body>

<div w3-include-html="h1.html"></div> 
<div w3-include-html="content.html"></div> 

<script>
includeHTML();
</script>

</body>

IPython is basically the "recommended" Python shell, which provides extra features. There is no language called IPython.

I found simple solution (I think) :

var marker = new google.maps.Marker();

function Clear(){
     marker.setMap(null);
}

Almost the same as skornos, but with variable declarations for a more explicit answer. It can work with Flask-RESTful extension:

from flask import Flask
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)

class UserAPI(Resource):
    def show(userId, username=None):
    pass

api.add_resource(UserAPI, '/<userId>', '/<userId>/<username>', endpoint='user')

if __name__ == '__main__':
    app.run()

The add_resource method allows pass multiples URLs. Each one will be routed to your Resource.

I ran into the same problem and here's how I was able to fix it

keytool -list -alias androiddebugkey -keystore <project_file\android\app\debug.keystore>

From GeekInterview:

In J2EE application, modules are packaged as EAR, JAR, and WAR based on their functionality

JAR: EJB modules which contain enterprise java beans (class files) and EJB deployment descriptor are packed as JAR files with .jar extension

WAR: Web modules which contain Servlet class files, JSP Files, supporting files, GIF and HTML files are packaged as a JAR file with .war (web archive) extension

EAR: All the above files (.jar and .war) are packaged as a JAR file with .ear (enterprise archive) extension and deployed into Application Server.

Just in case you guys have the url like localhost/index.xsp?a=1#something and you need to get the param not the hash.

var vars = [], hash, anchor;
var q = document.URL.split('?')[1];
if(q != undefined){
    q = q.split('&');
    for(var i = 0; i < q.length; i++){
        hash = q[i].split('=');
        anchor = hash[1].split('#');
        vars.push(anchor[0]);
        vars[hash[0]] = anchor[0];
    }
}

add {3,5} to your expression which means length between 3 to 5

/^([a-zA-Z0-9_-]){3,5}$/

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

CakePHP was intended to be used as Ruby on Rails framework clone, done in PHP, so any reverse-engineering of underlying database is pointless. EER diagrams should be reverse-engineered from Model layer.

Such tools do exist for Ruby Here you can see Redmine database EER diagrams reverse-engineered from Models. Not from database. http://redminecookbook.com/Redmine-erd-diagrams.html

With following tools: http://rails-erd.rubyforge.org/ http://railroady.prestonlee.com/

JAVA 8 lambda expression

Collections.sort(studList, (Student s1, Student s2) ->{
        return s1.getFirstName().compareToIgnoreCase(s2.getFirstName());
});

OR

Comparator<Student> c = (s1, s2) -> s1.firstName.compareTo(s2.firstName);
studList.sort(c)

The function will return true if the given string is in the right format('MM/DD/YYYY') else it will return false. (I found this code online & modified it a little)

function isValidDate(date) {_x000D_
    var temp = date.split('/');_x000D_
    var d = new Date(temp[2] + '/' + temp[0] + '/' + temp[1]);_x000D_
    return (d && (d.getMonth() + 1) == temp[0] && d.getDate() == Number(temp[1]) && d.getFullYear() == Number(temp[2]));_x000D_

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

Using dependency injection in your constructor makes managing the lifetime of your HttpClient easier - taking the lifetime managemant outside of the code that needs it and making it easily changable at a later date.

My current preference is to create a seperate http client class that inherits from HttpClient once per target endpoint domain and then make it a singleton using dependency injection. public class ExampleHttpClient : HttpClient { ... }

Then I take a constructor dependency on the custom http client in the service classes where I need access to that API. This solves the lifetime problem and has advantages when it comes to connection pooling.

You can see a worked example in related answer at https://stackoverflow.com/a/50238944/3140853

1. crop would be a more reusable function if you separate the cropping code from the image saving code. It would also make the call signature simpler.
2. im.crop returns a Image._ImageCrop instance. Such instances do not have a save method. Instead, you must paste the Image._ImageCrop instance onto a new Image.Image
3. Your ranges do not have the right step sizes. (Why height-2 and not height? for example. Why stop at imgheight-(height/2)?).

So, you might try instead something like this:

import Image
import os

def crop(infile,height,width):
    im = Image.open(infile)
    imgwidth, imgheight = im.size
    for i in range(imgheight//height):
        for j in range(imgwidth//width):
            box = (j*width, i*height, (j+1)*width, (i+1)*height)
            yield im.crop(box)

if __name__=='__main__':
    infile=...

If you set up a JBoss server using the Eclipse WebTools, you can simply start the server in debug mode (debug button in the servers view). This will allow you to set breakpoints in the application that is running inside the JBoss.

I use @gnarf's method, though I fall back on document.writelning a <script> tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:

if (horus.script.broken) {
    document.writeln('<script type="text/javascript" src="'+script+'"></script>');   
    horus.script.loaded(script);
} else {
    var s=document.createElement('script');
    s.type='text/javascript';
    s.src=script;
    s.async=true;

    if (horus.brokenDOM){
        s.onreadystatechange=
            function () {
                if (this.readyState=='loaded' || this.readyState=='complete'){
                    horus.script.loaded(script);
                }
        }
    }else{
        s.onload=function () { horus.script.loaded(script) };
    }

    document.head.appendChild(s);
}

where horus.script.loaded() notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).

The code posted in the question is obviously not a a complete example (it's not adding anything to the arraylist, it's not defining i anywhere).

First as others have said you need to understand the difference between primitive types and the class types that box them. E.g. Integer boxes int, Double boxes double, Long boxes long and so-on. Java automatically boxes and unboxes in various scenarios (it used to be you had to box and unbox manually with library calls but that was deemed an ugly PITA).

http://docs.oracle.com/javase/tutorial/java/data/autoboxing.html

You can mostly cast from one primitive type to another (the exception being boolean) but you can't do the same for boxed types. To convert one boxed type to another is a bit more complex. Especially if you don't know the box type in advance. Usually it will involve converting via one or more primitive types.

So the answer to your question depends on what is in your arraylist, if it's just objects of type Integer you can do.

sum = ((double)(int)marks.get(i));

The cast to int will behind the scenes first cast the result of marks.get to Integer, then it will unbox that integer. We then use another cast to convert the primitive int to a primitive double. Finally the result will be autoboxed back into a Double when it is assigned to the sum variable. (asside, it would probablly make more sense for sum to be of type double rather than Double in most cases).

If your arraylist contains a mixture of types but they all implement the Number interface (Integer, Short, Long, Float and Double all do but Character and Boolean do not) then you can do.

sum = ((Number)marks.get(i)).doubleValue();

If there are other types in the mix too then you might need to consider using the instanceof operator to identify them and take appropriate action.

I had this problem when I was trying to call a WCF service hosted in a new server from a windows application from my local. I was getting same error message and at end had this "No connection could be made because the target machine actively refused it 127.0.0.1:8888". I donot know whether I am wrong or correct but I feel whenever the server was getting request from my windows application it is routing to something else. So I did some reading and added below in Web.config of service host project. After that everything worked like a magic.

<system.net>
    <defaultProxy enabled="false">
    </defaultProxy>
</system.net>

In C++11 you can use std::to_string:

#include <string>

std::string s = std::to_string(5);

If you're working with prior to C++11, you could use C++ streams:

#include <sstream>

int i = 5;
std::string s;
std::stringstream out;
out << i;
s = out.str();

Have you tried setOnFocusChangeListener? Within the handler, you could change the text appearance.

For instance:

TextView text = (TextView)findViewById(R.id.text);
text.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            ((TextView)v).setXXXX();
        } else {
            ((TextView)v).setXXXX();
        }
    }
});

You can then apply whatever changes you want when it's focused or not. You can also use the ViewTreeObserver to listen for Global focus changes.

For instance:

View all = findViewById(R.id.id_of_top_level_view_on_layout);
ViewTreeObserver vto = all.getViewTreeObserver();
vto.addOnGlobalFocusChangeListener(new ViewTreeObserver.OnGlobalFocusChangeListener() {
    public void onGlobalFocusChanged(
        View oldFocus, View newFocus) {
        // xxxx
    }
});

I hope this helps or gives you ideas.

This will help exactly what you want

replace dt - your datetime c - call field astro_transit1 - your table 300 refer 5 min so add 300 each time for time gap increase

SELECT FROM_UNIXTIME( 300 * ROUND( UNIX_TIMESTAMP( r.dt ) /300 ) ) AS 5datetime, (
SELECT r.c
FROM astro_transit1 ra
WHERE ra.dt = r.dt
ORDER BY ra.dt DESC

If you are using this other path a lot of the time you can fix this permanently without having to specify the path all of the time. By default, it is checking for partial views in the View folder and in the Shared folder. But say you want to add one.

Add a class to your Models folder:

public class NewViewEngine : RazorViewEngine {

   private static readonly string[] NEW_PARTIAL_VIEW_FORMATS = new[] {
      "~/Views/Foo/{0}.cshtml",
      "~/Views/Shared/Bar/{0}.cshtml"
   };

   public NewViewEngine() {
      // Keep existing locations in sync
      base.PartialViewLocationFormats = base.PartialViewLocationFormats.Union(NEW_PARTIAL_VIEW_FORMATS).ToArray();
   }
}

Then in your Global.asax.cs file, add the following line:

ViewEngines.Engines.Add(new NewViewEngine());

This problem happens because IIS does not know about woff and woff2 file mime types.

Solution 1:

Add these lines in your web.config project:

 <system.webServer>
  ...
  </modules>
    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
      <remove fileExtension=".woff2" />
      <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
    </staticContent>

Solution 2:

On IIS project page:

Step 1: Go to your project IIS home page and double click on MIME Types button:

Step 2: Click on Add button from Actions menu:

Step 3: In the middle of the screen appears a window and in this window you need to add the two lines from solution 1:

If you want to make multiple operation use

select (sel1.s1+sel2+s2)

(select sum(hours) s1 from resource) sel1
join 
(select sum(hours) s2 from projects-time)sel2
on sel1.s1=sel2.s2

As mentioned by @Rafael Almeida, the problem you are having is caused by an untrusted SSL certificate. In my case, the SSL certificate was untrusted by my server. To get around this without compromising security, I downloaded the certificate, and installed it on the server (by simply double clicking on the .crt file and then Install Certificate...).

there are two ways to do this in jquery depending what you are looking for..

using jquery you can do

• //this will wait for the text assets to be loaded before calling this (the dom.. css.. js)

  $(document).ready(function(){...});
  

• //this will wait for all the images and text assets to finish loading before executing

  $(window).load(function(){...});
  

long/int to the byte array looks like exact purpose of struct.pack. For long integers that exceed 4(8) bytes, you can come up with something like the next:

>>> limit = 256*256*256*256 - 1
>>> i = 1234567890987654321
>>> parts = []
>>> while i:
        parts.append(i & limit)
        i >>= 32

>>> struct.pack('>' + 'L'*len(parts), *parts )
'\xb1l\x1c\xb1\x11"\x10\xf4'

>>> struct.unpack('>LL', '\xb1l\x1c\xb1\x11"\x10\xf4')
(2976652465L, 287445236)
>>> (287445236L << 32) + 2976652465L
1234567890987654321L

The Tuple approach :

This solution provides a strict FixedLengthArray (ak.a. SealedArray) type signature based in Tuples.

Syntax example :

// Array containing 3 strings
let foo : FixedLengthArray<[string, string, string]> 

This is the safest approach, considering it prevents accessing indexes out of the boundaries.

Implementation :

type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' | 'unshift' | number
type ArrayItems<T extends Array<any>> = T extends Array<infer TItems> ? TItems : never
type FixedLengthArray<T extends any[]> =
  Pick<T, Exclude<keyof T, ArrayLengthMutationKeys>>
  & { [Symbol.iterator]: () => IterableIterator< ArrayItems<T> > }

Tests :

var myFixedLengthArray: FixedLengthArray< [string, string, string]>

// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ]  // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ]  // ? TYPE ERROR
myFixedLengthArray = [ 'a' ]            // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ]       // ? LENGTH ERROR

// Index assignment tests 
myFixedLengthArray[1] = 'foo'           // ? OK
myFixedLengthArray[1000] = 'foo'        // ? INVALID INDEX ERROR

// Methods that mutate array length
myFixedLengthArray.push('foo')          // ? MISSING METHOD ERROR
myFixedLengthArray.pop()                // ? MISSING METHOD ERROR

// Direct length manipulation
myFixedLengthArray.length = 123         // ? READ-ONLY ERROR

// Destructuring
var [ a ] = myFixedLengthArray          // ? OK
var [ a, b ] = myFixedLengthArray       // ? OK
var [ a, b, c ] = myFixedLengthArray    // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? INVALID INDEX ERROR

(*) This solution requires the noImplicitAny typescript configuration directive to be enabled in order to work (commonly recommended practice)

The Array(ish) approach :

This solution behaves as an augmentation of the Array type, accepting an additional second parameter(Array length). Is not as strict and safe as the Tuple based solution.

Syntax example :

let foo: FixedLengthArray<string, 3> 

Keep in mind that this approach will not prevent you from accessing an index out of the declared boundaries and set a value on it.

Implementation :

type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' |  'unshift'
type FixedLengthArray<T, L extends number, TObj = [T, ...Array<T>]> =
  Pick<TObj, Exclude<keyof TObj, ArrayLengthMutationKeys>>
  & {
    readonly length: L 
    [ I : number ] : T
    [Symbol.iterator]: () => IterableIterator<T>   
  }

Tests :

var myFixedLengthArray: FixedLengthArray<string,3>

// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ]  // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ]  // ? TYPE ERROR
myFixedLengthArray = [ 'a' ]            // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ]       // ? LENGTH ERROR

// Index assignment tests 
myFixedLengthArray[1] = 'foo'           // ? OK
myFixedLengthArray[1000] = 'foo'        // ? SHOULD FAIL

// Methods that mutate array length
myFixedLengthArray.push('foo')          // ? MISSING METHOD ERROR
myFixedLengthArray.pop()                // ? MISSING METHOD ERROR

// Direct length manipulation
myFixedLengthArray.length = 123         // ? READ-ONLY ERROR

// Destructuring
var [ a ] = myFixedLengthArray          // ? OK
var [ a, b ] = myFixedLengthArray       // ? OK
var [ a, b, c ] = myFixedLengthArray    // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? SHOULD FAIL

Put a call to DoEvents in the loop.

This will affect performance, so you might want to only call it on each, say, 10th iteration.
However, if you only have 30, that's hardly an issue.

I can't believe so many people are posting answers without reading the JSON properly.

If you foreach iterate $json_a alone, you have an object of objects. Even if you pass in true as the second parameter, you have a two-dimensional array. If you're looping through the first dimension you can't just echo the second dimension like that. So this is wrong:

foreach ($json_a as $k => $v) {
   echo $k, ' : ', $v;
}

To echo the statuses of each person, try this:

<?php

$string = file_get_contents("/home/michael/test.json");
if ($string === false) {
    // deal with error...
}

$json_a = json_decode($string, true);
if ($json_a === null) {
    // deal with error...
}

foreach ($json_a as $person_name => $person_a) {
    echo $person_a['status'];
}

?>

Try:
$data = file_get_contents ("file.json");
        $json = json_decode($data, true);
        foreach ($json as $key => $value) {
            if (!is_array($value)) {
                echo $key . '=>' . $value . '<br/>';
            } else {
                foreach ($value as $key => $val) {
                    echo $key . '=>' . $val . '<br/>';
                }
            }
        }

I had this same need i started with bobbin's first example and ended up with this

  function add_business_days($startdate,$buisnessdays,$holidays=array(),$dateformat){
    $enddate = strtotime($startdate);
    $day = date('N',$enddate);
    while($buisnessdays > 1){
        $enddate = strtotime(date('Y-m-d',$enddate).' +1 day');
        $day = date('N',$enddate);
        if($day < 6 && !in_array($enddate,$holidays))$buisnessdays--;
    }
    return date($dateformat,$enddate);
  }

There's a facility to have a separate style sheet for print, using

 <link type="text/css" rel="stylesheet" media="print" href="print.css">

I don't know if it does what you want though.

Here is an answer with support to IE using object-fit so you won't lose ratio

Using a simple JS snippet to detect if the object-fit is supported and then replace the img for a svg

//ES6 version
if ('objectFit' in document.documentElement.style === false) {
  document.addEventListener('DOMContentLoaded', () => {
    document.querySelectorAll('img[data-object-fit]').forEach(image => {
      (image.runtimeStyle || image.style).background = `url("${image.src}") no-repeat 50%/${image.currentStyle ? image.currentStyle['object-fit'] : image.getAttribute('data-object-fit')}`
      image.src = `data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='${image.width}' height='${image.height}'%3E%3C/svg%3E`
    })
  })
}

//ES5 version
if ('objectFit' in document.documentElement.style === false) {
  document.addEventListener('DOMContentLoaded', function() {
    Array.prototype.forEach.call(document.querySelectorAll('img[data-object-fit]').forEach(function(image) {
      (image.runtimeStyle || image.style).background = "url(\"".concat(image.src, "\") no-repeat 50%/").concat(image.currentStyle ? image.currentStyle['object-fit'] : image.getAttribute('data-object-fit'));
      image.src = "data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='".concat(image.width, "' height='").concat(image.height, "'%3E%3C/svg%3E");
    }));
  });
}

img {
  display: inline-flex;
  width: 175px;
  height: 175px;
  margin-right: 10px;
  border: 1px solid red
}


/*for browsers which support object fit */

[data-object-fit='cover'] {
  object-fit: cover
}

[data-object-fit='contain'] {
  object-fit: contain
}

<img data-object-fit='cover' src='//picsum.photos/1200/600' />
<img data-object-fit='contain' src='//picsum.photos/1200/600' />
<img src='//picsum.photos/1200/600' />

Note: There are also a few object-fit polyfills out there that will make object-fit work.

Here are a few examples:

• object-fit-images
• constancecchen /object-fit-pollyfill
• Polyfill for CSS object-fit property

You can save the current cookies as a Python object using pickle. For example:

import pickle
import selenium.webdriver

driver = selenium.webdriver.Firefox()
driver.get("http://www.google.com")
pickle.dump( driver.get_cookies() , open("cookies.pkl","wb"))

And later to add them back:

import pickle
import selenium.webdriver

driver = selenium.webdriver.Firefox()
driver.get("http://www.google.com")
cookies = pickle.load(open("cookies.pkl", "rb"))
for cookie in cookies:
    driver.add_cookie(cookie)

read the following article http://mycodelines.wordpress.com/2009/09/01/in-which-scenario-we-use-abstract-classes-and-interfaces/

Abstract Classes

–> When you have a requirement where your base class should provide default implementation of certain methods whereas other methods should be open to being overridden by child classes use abstract classes.

For e.g. again take the example of the Vehicle class above. If we want all classes deriving from Vehicle to implement the Drive() method in a fixed way whereas the other methods can be overridden by child classes. In such a scenario we implement the Vehicle class as an abstract class with an implementation of Drive while leave the other methods / properties as abstract so they could be overridden by child classes.

–> The purpose of an abstract class is to provide a common definition of a base class that multiple derived classes can share.

For example a class library may define an abstract class that is used as a parameter to many of its functions and require programmers using that library to provide their own implementation of the class by creating a derived class.

Use an abstract class

When creating a class library which will be widely distributed or reused—especially to clients, use an abstract class in preference to an interface; because, it simplifies versioning. This is the practice used by the Microsoft team which developed the Base Class Library. ( COM was designed around interfaces.) Use an abstract class to define a common base class for a family of types. Use an abstract class to provide default behavior. Subclass only a base class in a hierarchy to which the class logically belongs.

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

To manually generate a Certificate, you need a Certificate Signing Request (CSR) file from your Mac. To create a CSR file, follow the instructions below to create one using Keychain Access.

Create a CSR file. In the Applications folder on your Mac, open the Utilities folder and launch Keychain Access.

Within the Keychain Access drop down menu, select Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority.

In the Certificate Information window, enter the following information: In the User Email Address field, enter your email address. In the Common Name field, create a name for your private key (e.g., John Doe Dev Key). The CA Email Address field should be left empty. In the "Request is" group, select the "Saved to disk" option. Click Continue within Keychain Access to complete the CSR generating process.

You still have to wrap it in an ISERROR, but you could use MATCH() instead of VLOOKUP():

Returns the relative position of an item in an array that matches a specified value in a specified order. Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself.

Here's a complete example, assuming you're looking for the word "key" in a range of cells:

=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")

The FALSE is necessary to force an exact match, otherwise it will look for the closest value.

Errr, it's a bit messy in the view. But I think I've gotten it to work with group (http://mongoid.org/docs/querying/)

Controller

@event_attendees = Activity.only(:user_id).where(:action => 'Attend').order_by(:created_at.desc).group

View

<% @event_attendees.each do |event_attendee| %>    
  <%= event_attendee['group'].first.user.first_name %>
<% end %>

This was bugging me too, since this was a standard feature in Sublime Text 2, but somehow automatic indentation no longer worked in Sublime Text 3 for HTML files.

My solution was to find the Miscellaneous.tmPreferences file from Sublime Text 2 (found under %AppData%/Roaming/Sublime Text 2/Packages/HTML) and copy those settings to the same file for ST3.

Now package handling has been made more difficult for ST3, but luckily you can just add the files to your %AppData%/Roaming/Sublime Text 3/Packages folder and they overwrite default settings in the install directory. Just save this file as "%AppData%/Roaming/Sublime Text 3/Packages/HTML/Miscellaneous.tmPreferences" and auto indent works again like it did in ST2.

hi if are you new in android use this way Apply your view to make it gone GONE is one way, else, get hold of the parent view, and remove the child from there..... else get the parent layout and use this method an remove all child parentView.remove(child)

I would suggest using the GONE approach...

('my string'.match(/\s/g) || []).length;

The class is .navbar-default. You need to create a class on your custom css .navbar-default.And follow the css code. Also if you don’t want box-shadow on your menu, you can put on the same class.

 .navbar-default {
      background-color:transparent !important;
      border-color:transparent;
      background-image:none;
      box-shadow:none;  
 }

To change font navbar color, the class is to change – .navbar-default .navbar-nav>li>a see the code bellow:

  .navbar-default .navbar-nav>li>a {
     font-size:20px; 
     color:#fff; 
 }

add delim_whitespace=True argument, it's faster than regex.

If you just want the INSERT queries, use the following:

mysqldump --skip-triggers --compact --no-create-info

if you using jpa repository, set properties.put("hibernate.enable_lazy_load_no_trans",true); to jpaPropertymap

I believe you're not fully understanding how pointers work.
When you have a pointer pointing to some memory there are three different things you must understand:
- there is "what is pointed" by the pointer (the memory)
- this memory address
- not all pointers need to have their memory deleted: you only need to delete memory that was dynamically allocated (used new operator).

Imagine:

int *ptr = new int; 
// ptr has the address of the memory.
// at this point, the actual memory doesn't have anything.
*ptr = 8;
// you're assigning the integer 8 into that memory.
delete ptr;
// you are only deleting the memory.
// at this point the pointer still has the same memory address (as you could
//   notice from your 2nd test) but what inside that memory is gone!

When you did

ptr = NULL;
// you didn't delete the memory
// you're only saying that this pointer is now pointing to "nowhere".
// the memory that was pointed by this pointer is now lost.

C++ allows that you try to delete a pointer that points to null but it doesn't actually do anything, just doesn't give any error.

You can use File.WriteAllBytes

(update: 2018)

Note that pd.Timegrouper is depreciated and will be removed. Use instead:

 df.groupby(pd.Grouper(freq='M'))

Yep, but you have to put the array first in the expression:

... | where { @("user1","user2") -notlike $_.username }

-Oisin

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

You can use the iframe's load event to respond when the iframe loads.

document.querySelector('iframe').onload = function(){
    console.log('iframe loaded');
};

This won't tell you whether the correct content loaded: To check that, you can inspect the contentDocument.

document.querySelector('iframe').onload = function(){
    var iframeBody = this.contentDocument.body;
    console.log('iframe loaded, body is: ', body);
};

Checking the contentDocument won't work if the iframe src points to a different domain from where your code is running.

I had an issue at work. The oracle server was "patched" and one of the databases I use could not be connect via the TNSNames entry but via Basic connection. The Database was up and admin could see it was up and running.

Addionally any application that used TNS for connecting to the database would not work either.

The problem found was that the database name was not correct in the TNS file but for some reason it's been working for years. Correcting the name fixed it for us. I did find that Oracle SQL Developer kept using the old TNS entry even after I updated it and I don't feel like reinstalling it for just one DB Connection. It appears that when the database was created it was given a smaller name then the others and via some cut and paste action within the TNSNames file it got mixed up. No one is sure how its worked as we're investigating it but the oracle patch ensured that the name had to be correct

An example of the name was it was down as "DBName.Part1.Part2" but in fact the DB name was "DBName"

to reattach this object, you must use merge();

this methode accept in parameter your entity detached and return an entity will be attached and reloaded from Database.

Example :
    Lot objAttach = em.merge(oldObjDetached);
    objAttach.setEtat(...);
    em.persist(objAttach);

You can do this too:

oldIFS="$IFS"
IFS=$'\n' arr=($(<file))
IFS="$oldIFS"
echo "${arr[1]}" # It will print `A Dog`.

Note:

Filename expansion still occurs. For example, if there's a line with a literal * it will expand to all the files in current folder. So use it only if your file is free of this kind of scenario.

It is even easier in Swift:

let string : String = "Hello  "
let characters = Array(string)
println(characters)
// [H, e, l, l, o,  , , ,  , ]

This uses the facts that

• an Array can be created from a SequenceType, and
• String conforms to the SequenceType protocol, and its sequence generator enumerates the characters.

And since Swift strings have full support for Unicode, this works even with characters outside of the "Basic Multilingual Plane" (such as ) and with extended grapheme clusters (such as , which is actually composed of two Unicode scalars).

Update: As of Swift 2, String does no longer conform to SequenceType, but the characters property provides a sequence of the Unicode characters:

let string = "Hello  "
let characters = Array(string.characters)
print(characters)

This works in Swift 3 as well.

Update: As of Swift 4, String is (again) a collection of its Characters:

let string = "Hello  "
let characters = Array(string)
print(characters)
// ["H", "e", "l", "l", "o", " ", "", "", " ", ""]

It sounds like your printMousePos function should:

1. Get the X and Y coordinates of the mouse
2. Add those values to the HTML

Currently, it does this:

1. Creates (undefined) variables for the X and Y coordinates of the mouse
2. Attaches a function to the "mousemove" event (which will set those variables to the mouse coordinates when triggered by a mouse move)
3. Adds the current values of your variables to the HTML

See the problem? Your variables are never getting set, because as soon as you add your function to the "mousemove" event you print them.

It seems like you probably don't need that mousemove event at all; I would try something like this:

function printMousePos(e) {
    var cursorX = e.pageX;
    var cursorY = e.pageY;
    document.getElementById('test').innerHTML = "x: " + cursorX + ", y: " + cursorY;
}

Write-back and write-through describe policies when a write hit occurs, that is when the cache has the requested information. In these examples, we assume a single processor is writing to main memory with a cache.

Write-through: The information is written to the cache and memory, and the write finishes when both have finished. This has the advantage of being simpler to implement, and the main memory is always consistent (in sync) with the cache (for the uniprocessor case - if some other device modifies main memory, then this policy is not enough), and a read miss never results in writes to main memory. The obvious disadvantage is that every write hit has to do two writes, one of which accesses slower main memory.

Write-back: The information is written to a block in the cache. The modified cache block is only written to memory when it is replaced (in effect, a lazy write). A special bit for each cache block, the dirty bit, marks whether or not the cache block has been modified while in the cache. If the dirty bit is not set, the cache block is "clean" and a write miss does not have to write the block to memory.

The advantage is that writes can occur at the speed of the cache, and if writing within the same block only one write to main memory is needed (when the previous block is being replaced). The disadvantages are that this protocol is harder to implement, main memory can be not consistent (not in sync) with the cache, and reads that result in replacement may cause writes of dirty blocks to main memory.

The policies for a write miss are detailed in my first link.

These protocols don't take care of the cases with multiple processors and multiple caches, as is common in modern processors. For this, more complicated cache coherence mechanisms are required. Write-through caches have simpler protocols since a write to the cache is immediately reflected in memory.

I've tried different numbers, and it always acts as if the 0s aren't there and sorts the numbers correctly otherwise. Anyone know why?

You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Javascript:

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort

array.sort([compareFunction])

Parameters

compareFunction

Specifies a function that defines the sort order. If omitted, the array is sorted lexicographically (in dictionary order) according to the string conversion of each element.

In the ECMAscript specification (the normative reference for the generic Javascript), ECMA-262, 3rd ed., section 15.4.4.11, the default sort order is lexicographical, although they don't come out and say it, instead giving the steps for a conceptual sort function that calls the given compare function if necessary, otherwise comparing the arguments when converted to strings:

13. If the argument comparefn is undefined, go to step 16.
14. Call comparefn with arguments x and y.
15. Return Result(14).
16. Call ToString(x).
17. Call ToString(y).
18. If Result(16) < Result(17), return -1.
19. If Result(16) > Result(17), return 1.
20. Return +0.

I'm a java developer that happened to get on a team without a DBA and one where as a developer, I can't get DBA rights. I was tasked with moving an entire schema between two databases, so without having a DBA, I had to do it and do it by running scripts, not being able to use the GUI in SQL Server 2008 because I didn't have admin privileges.

Everything was moved without issue, however, when running a stored procedure on the new schema.table, I found I lost the identity field in a table. I double checked the script that created the table and it was there, however, SQL Server didn't get it when I ran the script. I was told later by a DBA that he had seen this same problem before.

In any event, for SQL Server 2008, these are the steps I took to get this resolved and they worked, so I'm posting this here in the hopes it will be a help to someone. This is what I did as I had FK dependencies on another table that made this more difficult:

I used this query to verify the identity was indeed missing and to view dependencies on the table.

1.) Find statistics on a table:

exec sp_help 'dbo.table_name_old';

2.) Create a duplicate, identical new table, except add an identity field on the PK field where it had been before.

3.) Disable the identity to move data.

SET IDENTITY_INSERT dbo.table_name ON 

4.) Transfer the data.

INSERT INTO dbo.table_name_new
(
field1, field2, etc...
)
SELECT 
field1, field2, etc...
FROM 
dbo.table_name_old;

5.) Verify the data is there.

SELECT * FROM dbo.table_name_new

6.) Re-enable the identity.

SET IDENTITY_INSERT ToyRecP.ToyAwards.lkpFile_New OFF

7.) This is the best script I found to get all the FK relationships to verify which table(s) the original table references as dependencies and I came across many, so it is a keeper!

SELECT f.name AS ForeignKey,
   OBJECT_NAME(f.parent_object_id) AS TableName,
   COL_NAME(fc.parent_object_id, fc.parent_column_id) AS ColumnName,
   OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName,
   COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS ReferenceColumnName
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
   ON f.OBJECT_ID = fc.constraint_object_id
   ORDER BY ReferenceTableName;

8.) Make sure you have all the PK and FK scripts for all the tables involved, before this next step.

9.) You can right-click on each key and script this using SQL Server 2008

10.) Drop the FK(s) from the dependency table(s) using this syntax:

ALTER TABLE [dbo].[table_name] DROP CONSTRAINT [Name_of_FK]

11.) Drop the original table:

DROP TABLE dbo.table_name_old;

13.) These next steps rely on the scripts you created in SQL Server 2008 in step 9.

--Add the PK to the new table.

--Add the FK to the new table.

--Add the FK's back to the dependency table.

14.) Verify everything is correct and complete. I used the GUI to look at the tables.

15.) Rename the new table to the original tables name.

exec sp_RENAME '[Schema_Name.OldTableName]' , '[NewTableName]';

Finally, everything worked!

One method is to add a new event listener that calls e.stopImmediatePropagation().

Although conceptually the same as Asaph's answer (benefiting from the same cross-browser compatibility, even IE6), it is a lot smaller and comes in handy when size is at a premium and/or when it is not needed so often.

function childOf(/*child node*/c, /*parent node*/p){ //returns boolean
  while((c=c.parentNode)&&c!==p); 
  return !!c; 
}

..or as one-liner (just 64 chars!):

function childOf(c,p){while((c=c.parentNode)&&c!==p);return !!c}

and jsfiddle here.

Usage:
childOf(child, parent) returns boolean true|false.

Explanation:
while evaluates as long as the while-condition evaluates to true.
The && (AND) operator returns this boolean true/false after evaluating the left-hand side and the right-hand side, but only if the left-hand side was true (left-hand && right-hand).

The left-hand side (of &&) is: (c=c.parentNode).
This will first assign the parentNode of c to c and then the AND operator will evaluate the resulting c as a boolean.
Since parentNode returns null if there is no parent left and null is converted to false, the while-loop will correctly stop when there are no more parents.

The right-hand side (of &&) is: c!==p.
The !== comparison operator is 'not exactly equal to'. So if the child's parent isn't the parent (you specified) it evaluates to true, but if the child's parent is the parent then it evaluates to false.
So if c!==p evaluates to false, then the && operator returns false as the while-condition and the while-loop stops. (Note there is no need for a while-body and the closing ; semicolon is required.)

So when the while-loop ends, c is either a node (not null) when it found a parent OR it is null (when the loop ran through to the end without finding a match).

Thus we simply return that fact (converted as boolean value, instead of the node) with: return !!c;: the ! (NOT operator) inverts a boolean value (true becomes false and vice-versa).
!c converts c (node or null) to a boolean before it can invert that value. So adding a second ! (!!c) converts this false back to true (which is why a double !! is often used to 'convert anything to boolean').

Extra:
The function's body/payload is so small that, depending on case (like when it is not used often and appears just once in the code), one could even omit the function (wrapping) and just use the while-loop:

var a=document.getElementById('child'),
    b=document.getElementById('parent'),
    c;

c=a; while((c=c.parentNode)&&c!==b); //c=!!c;

if(!!c){ //`if(c)` if `c=!!c;` was used after while-loop above
    //do stuff
}

instead of:

var a=document.getElementById('child'),
    b=document.getElementById('parent'),
    c;

function childOf(c,p){while((c=c.parentNode)&&c!==p);return !!c}

c=childOf(a, b);    

if(c){ 
    //do stuff
}

As mentioned in the presentation at the I/O (about 4:05), Volley "is terrible" for large payloads. As I understand it that means not to use Volley for receiving/sending (big) files. Looking at the code it seems that it is not even designed to handle multipart form data (e.g. Request.java has getBodyContentType() with hardcoded "application/x-www-form-urlencoded"; HttpClientStack::createHttpRequest() can handle only byte[], etc...). Probably you will be able to create implementation that can handle multipart but If I were you I will just use HttpClient directly with MultipartEntity like:

    HttpPost req = new HttpPost(composeTargetUrl());
    MultipartEntity entity = new MultipartEntity();
    entity.addPart(POST_IMAGE_VAR_NAME, new FileBody(toUpload));
    try {
        entity.addPart(POST_SESSION_VAR_NAME, new StringBody(uploadSessionId));
    } catch (UnsupportedEncodingException e) {
        throw new RuntimeException(e);
    }
    req.setEntity(entity);

You may need newer HttpClient (i.e. not the built-in) or even better, use Volley with newer HttpClient

The modern way to do it that maintains the order is:

>>> from collections import OrderedDict
>>> list(OrderedDict.fromkeys(lseparatedOrbList))

as discussed by Raymond Hettinger (python core dev) in this answer. In python 3.5 and above this is also the fastest way - see the linked answer for details. However the keys must be hashable (as is the case in your list I think)

Your method must be static

static void setTextboxText(int result)
{
    if (this.InvokeRequired)
    {
        this.Invoke(new IntDelegate(SetTextboxTextSafe), new object[] { result }); 
    }
    else
    {
        SetTextboxTextSafe(result);
    }
}

SpringApplication implicitly registers a shutdown hook with the JVM to ensure that ApplicationContext is closed gracefully on exit. That will also call all bean methods annotated with @PreDestroy. That means we don't have to explicitly use the registerShutdownHook() method of a ConfigurableApplicationContext in a boot application, like we have to do in spring core application.

@SpringBootConfiguration
public class ExampleMain {
    @Bean
    MyBean myBean() {
        return new MyBean();
    }

    public static void main(String[] args) {
        ApplicationContext context = SpringApplication.run(ExampleMain.class, args);
        MyBean myBean = context.getBean(MyBean.class);
        myBean.doSomething();

        //no need to call context.registerShutdownHook();
    }

    private static class MyBean {

        @PostConstruct
        public void init() {
            System.out.println("init");
        }

        public void doSomething() {
            System.out.println("in doSomething()");
        }

        @PreDestroy
        public void destroy() {
            System.out.println("destroy");
        }
    }
}

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.

Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.

DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj

...

The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.

var DyObjectsList = new List<dynamic>; 
if (condition1) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = true; 
    DyObj.Message = "Message 1"; 
    DyObjectsList .Add(DyObj); 
} 
if (condition2) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = false; 
    DyObj.Message = "Message 2"; 
    DyObjectsList .Add(DyObj); 
} 

your resulting List essentially looks like this

DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj

Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.

However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.

There are really great answers above to the asked question. There might be no need for another answer but still I want to give my personal opinion on the topic in the simplest words possible.

Here are some points about containers & images that will help us for a conclusion:

• A docker image can be:
  1. created-from-a-given-container
  2. deleted
  3. used-to-create-any-number-of-containers
• A docker container can be:
  1. created-from-an-image
  2. started
  3. stopped
  4. restarted
  5. deleted
  6. used-to-create-any-number-of-images
• A docker run command does this:
  1. Downloads an image or uses a cached image
  2. Creates a new container out of it
  3. Starts the container
• When a Dockerfile is used to create an image:
  1. It is already well known that the image will eventually be used to run a docker container.
  2. After issuing docker build command, docker behind-the-scenes creates a running container with a base-file-system and follows steps inside the Dockerfile to configure that container as per the developers need.
  3. After the container is configured with specs of the Dockerfile, it will be committed as an image.
  4. The image gets ready to rock & roll!

Conclusion:

As we can see, a docker container is independent of a docker image.

A container can be restarted provided the unique ID of that container [use docker ps --all to get the id].

Any operation like making a new directory, creating files, installing tools, etc. can be done inside the container when it is running. Once the container is stopped, it persists all the changes. Container stopping and restarting is like rebooting a computer system.

An already created container is always available for a restart but when we issue docker run command, a new container is created out of an image and hence it is like a new computer system. The changes made inside the old container - as we can understand now - are not available in this new container.

A final note:

I guess it's now obvious why the data seems to be lost yet it is always there.. but in a different [old] container. So, take a good note of the difference in docker start & docker run command & never get confused in them.

The following code allows you to benefit from all SSL validation checks (e.g. date validity, CA certificate chain ...) EXCEPT a pluggable verification step e.g. to verify the hostname or do other additional certificate verification steps.

from httplib import HTTPSConnection
import ssl


def create_custom_HTTPSConnection(host):

    def verify_cert(cert, host):
        # Write your code here
        # You can certainly base yourself on ssl.match_hostname
        # Raise ssl.CertificateError if verification fails
        print 'Host:', host
        print 'Peer cert:', cert

    class CustomHTTPSConnection(HTTPSConnection, object):
        def connect(self):
            super(CustomHTTPSConnection, self).connect()
            cert = self.sock.getpeercert()
            verify_cert(cert, host)

    context = ssl.create_default_context()
    context.check_hostname = False
    return CustomHTTPSConnection(host=host, context=context)


if __name__ == '__main__':
    # try expired.badssl.com or self-signed.badssl.com !
    conn = create_custom_HTTPSConnection('badssl.com')
    conn.request('GET', '/')
    conn.getresponse().read()

For quick reference of anyone who wants to go to the end of line or start of line in iTerm2, the above link http://hackaddict.blogspot.com/2007/07/skip-to-next-or-previous-word-in-iterm.html notes that in iTerm2:

• Ctrl+A, jumps to the start of the line, while
• Ctrl+E, jumps to the end of the line.

If using the command line, you'll need to use one of the packages listed with

sdkmanager --list | grep "playstore"

Once that is installed you can use the appropriate package in

avdmanager create avd --force --name testAVD --abi google_apis_playstore/x86_64 --package "system-images;android-28;google_apis_playstore;x86_64" -d 19

Replace google_apis_playstore;x86_64 with the package you installed

you can right click on a grid of results in SQL server, and choose save as CSV. you can then you can import this into Excel.

Excel gives you a import wizard, ensure you select comma delimited. it works fine for me when i needed to import 50k+ records into excel.

Maybe your dept_name columns have different charsets.

You could try to alter one or both of them:

ALTER TABLE department MODIFY dept_name VARCHAR(20) CHARACTER SET utf8;
ALTER TABLE course MODIFY dept_name VARCHAR(20) CHARACTER SET utf8;

you can create a shallow clone to only get the last few revisions:

 git clone --depth 1 git://url

then either simply delete the .git directory or use git archive to export your tree.

Good technical & logical question my dear friend. No in robots.txt file you can't go with relative URL of the sitemap; you need to go with the complete URL of the sitemap.

It's better to go with "sitemap: https://www.example.com/sitemap_index.xml"

In the above URL after the colon gives space. I also like to support Deepak.

This should work. But I have same problems on an Android phone.

<input type="number" /> <input type="tel" />

I found out, that if I didn't include the jquerymobile-framework, the keypad showed correctly on the two types of fields.

But I havn't found a solution to solve that problem, if you really need to use jquerymobile.

UPDATE: I found out, that if the form-tag is stored out of the

<div data-role="page"> 

The number keypad isn't shown. This must be a bug...

This one worked for me too

msiexec /i "msi path" INSTALLDIR="D:\myfolder" /q

I had tried two other iterations and both installed in the default C:\Program Files

INSTALLDIR="D:\myfolder" /q got it installed on the other drive.

For an iBeacon with ProximityUUID E2C56DB5-DFFB-48D2-B060-D0F5A71096E0, major 0, minor 0, and calibrated Tx Power of -59 RSSI, the transmitted BLE advertisement packet looks like this:

d6 be 89 8e 40 24 05 a2 17 6e 3d 71 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 52 ab 8d 38 a5

This packet can be broken down as follows:

d6 be 89 8e # Access address for advertising data (this is always the same fixed value)
40 # Advertising Channel PDU Header byte 0.  Contains: (type = 0), (tx add = 1), (rx add = 0)
24 # Advertising Channel PDU Header byte 1.  Contains:  (length = total bytes of the advertising payload + 6 bytes for the BLE mac address.)
05 a2 17 6e 3d 71 # Bluetooth Mac address (note this is a spoofed address)
02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 # Bluetooth advertisement
52 ab 8d 38 a5 # checksum

The key part of that packet is the Bluetooth Advertisement, which can be broken down like this:

02 # Number of bytes that follow in first AD structure
01 # Flags AD type
1A # Flags value 0x1A = 000011010  
   bit 0 (OFF) LE Limited Discoverable Mode
   bit 1 (ON) LE General Discoverable Mode
   bit 2 (OFF) BR/EDR Not Supported
   bit 3 (ON) Simultaneous LE and BR/EDR to Same Device Capable (controller)
   bit 4 (ON) Simultaneous LE and BR/EDR to Same Device Capable (Host)
1A # Number of bytes that follow in second (and last) AD structure
FF # Manufacturer specific data AD type
4C 00 # Company identifier code (0x004C == Apple)
02 # Byte 0 of iBeacon advertisement indicator
15 # Byte 1 of iBeacon advertisement indicator
e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 # iBeacon proximity uuid
00 00 # major 
00 00 # minor 
c5 # The 2's complement of the calibrated Tx Power

Any Bluetooth LE device that can be configured to send a specific advertisement can generate the above packet. I have configured a Linux computer using Bluez to send this advertisement, and iOS7 devices running Apple's AirLocate test code pick it up as an iBeacon with the fields specified above. See: Use BlueZ Stack As A Peripheral (Advertiser)

This blog has full details about the reverse engineering process.

You can call Stored Procedure like this inside Stored Procedure B.

CREATE PROCEDURE spA
@myDate DATETIME
AS
    EXEC spB @myDate

RETURN 0

I would zip the lists together to compare them element by element.

main_list = [b for a, b in zip(list1, list2) if a!= b]

The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.

The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).

Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime() method. You could have used Q or M or Monty Python and the method would have returned them unchanged as well; the method only looks for patterns starting with % to replace those with information from the datetime object.
