Builder is some kind of more complex Factory.

But in Builder you can instantiate objects with using another factories, that are required to build final and valid object.

So, talking about "Creational Patterns" evolution by complexity you can think about it in this way:

Dependency Injection Container -> Service Locator -> Builder -> Factory

To generate an inner builder in Intellij IDEA, check out this plugin: https://github.com/analytically/innerbuilder

For those using React, detecting a same-origin iframe load event is as simple as setting onLoad event listener on iframe element.

<iframe src={'path-to-iframe-source'} onLoad={this.loadListener} frameBorder={0} />

My solution reuses the one of amcdnl, but my fallback consist of using a height for the text container:

.my-caption h4 {
    display: -webkit-box;
    margin: 0 auto;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;
    overflow: hidden;
    text-overflow: ellipsis;

    height: 40px;/* Fallback for non-webkit */
}

What worked for me now is:

CSS:

.right {
  text-align: right;
  margin-right: 1em;
}

.left {
  text-align: left;
  margin-left: 1em;
}

HTML:

<table width="100%">
  <tbody>
    <tr>
      <td class="left">
        <input id="abort" type="submit" name="abort" value="Back">
        <input id="save" type="submit" name="save" value="Save">
      </td>
      <td class="right">
        <input id="delegate" type="submit" name="delegate" value="Delegate">
        <input id="unassign" type="submit" name="unassign" value="Unassign">
        <input id="complete" type="submit" name="complete" value="Complete">
      </td>
    </tr>
  </tbody>
</table>

See the following fiddle:

Please try with just giving the path from where you want to pull the files I just got the files from sdcard like

adb pull sdcard/

do NOT give * like to broaden the search or to filter out. ex: adb pull sdcard/*.txt --> this is invalid.

just give adb pull sdcard/

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

Following leppie's answer, why not make MetaData an interface:

public interface IMetaData { }

public class Metadata<DataType> : IMetaData where DataType : struct
{
    private DataType mDataType;
}

localhost is a special hostname that almost always resolves to 127.0.0.1. If you ask someone else to connect to http://localhost they'll be connecting to their computer instead or yours.

To share your web server with someone else you'll need to find your IP address or your hostname and provide that to them instead. On windows you can find this with ipconfig /all on a command line.

You'll also need to make sure any firewalls you may have configured allow traffic on port 80 to connect to the WAMP server.

You can use the CultureInfo to get the month name. You can even get the short month name as well as other fun things.

I would suggestion you put these into extension methods, which will allow you to write less code later. However you can implement however you like.

Here is an example of how to do it using extension methods:

using System;
using System.Globalization;

class Program
{
    static void Main()
    {

        Console.WriteLine(DateTime.Now.ToMonthName());
        Console.WriteLine(DateTime.Now.ToShortMonthName());
        Console.Read();
    }
}

static class DateTimeExtensions
{
    public static string ToMonthName(this DateTime dateTime)
    {
        return CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(dateTime.Month);
    }

    public static string ToShortMonthName(this DateTime dateTime)
    {
        return CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(dateTime.Month);
    }
}

Hope this helps!

You can use guide=FALSE in scale_..._...() to suppress legend.

For your example you should use scale_colour_continuous() because length is continuous variable (not discrete).

(p3 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
   scale_colour_continuous(guide = FALSE) +
   geom_point()
)

Or using function guides() you should set FALSE for that element/aesthetic that you don't want to appear as legend, for example, fill, shape, colour.

p0 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
  geom_point()    
p0+guides(colour=FALSE)

UPDATE

Both provided solutions work in new ggplot2 version 2.0.0 but movies dataset is no longer present in this library. Instead you have to use new package ggplot2movies to check those solutions.

library(ggplot2movies)
data(movies)
mov <- subset(movies, length != "")

But it's not hard to write one:

public class CaseInsensitiveIndexOfTest extends TestCase {
    public void testOne() throws Exception {
        assertEquals(2, caseInsensitiveIndexOf("ABC", "xxabcdef"));
    }

    public static int caseInsensitiveIndexOf(String substring, String string) {
        return string.toLowerCase().indexOf(substring.toLowerCase());
    }
}

For anyone still struggling with this, this simple extension in swift should fix the problem for you.

extension UINavigationController {
    override open var childForStatusBarStyle: UIViewController? {
        return self.topViewController
    }
}

I think you can leverage the [Zip File System Provider][1] to achieve this. When using FileSystems.newFileSystem it looks like you can treat the objects in that ZIP as a "regular" file.

In the linked documentation above:

Specify the configuration options for the zip file system in the java.util.Map object passed to the FileSystems.newFileSystem method. See the [Zip File System Properties][2] topic for information about the provider-specific configuration properties for the zip file system.

Once you have an instance of a zip file system, you can invoke the methods of the [java.nio.file.FileSystem][3] and [java.nio.file.Path][4] classes to perform operations such as copying, moving, and renaming files, as well as modifying file attributes.

The documentation for the jdk.zipfs module in [Java 11 states][5]:

The zip file system provider treats a zip or JAR file as a file system and provides the ability to manipulate the contents of the file. The zip file system provider can be created by [FileSystems.newFileSystem][6] if installed.

Here is a contrived example I did using your example resources. Note that a .zip is a .jar, but you could adapt your code to instead use classpath resources:

Setup

cd /tmp
mkdir -p x/y/z
touch x/y/z/{a,b,c}.html
echo 'hello world' > x/y/z/d
zip -r example.zip x

Java

import java.io.IOException;
import java.net.URI;
import java.nio.file.FileSystem;
import java.nio.file.FileSystems;
import java.nio.file.Files;
import java.util.Collections;
import java.util.stream.Collectors;

public class MkobitZipRead {

  public static void main(String[] args) throws IOException {
    final URI uri = URI.create("jar:file:/tmp/example.zip");
    try (
        final FileSystem zipfs = FileSystems.newFileSystem(uri, Collections.emptyMap());
    ) {
      Files.walk(zipfs.getPath("/")).forEach(path -> System.out.println("Files in zip:" + path));
      System.out.println("-----");
      final String manifest = Files.readAllLines(
          zipfs.getPath("x", "y", "z").resolve("d")
      ).stream().collect(Collectors.joining(System.lineSeparator()));
      System.out.println(manifest);
    }
  }

}

Output

Files in zip:/
Files in zip:/x/
Files in zip:/x/y/
Files in zip:/x/y/z/
Files in zip:/x/y/z/c.html
Files in zip:/x/y/z/b.html
Files in zip:/x/y/z/a.html
Files in zip:/x/y/z/d
-----
hello world

Short version of Franci's answer:

for(Iterator<String> iter = json.keys();iter.hasNext();) {
    String key = iter.next();
    ...
}

http://msdn.microsoft.com/en-us/library/f02979c7(v=VS.90).aspx

You can pass nothing if you don't need the returned integer like so

if integer.TryParse(number,nothing) then

string a = "10.65678";

decimal d = Math.Round(Convert.ToDouble(a.ToString()),2)

You don't free anything at all. Since you never acquired any resources dynamically, there is nothing you have to, or even are allowed to, free.

(It's the same as when you say int n = 10;: There are no dynamic resources involved that you have to manage manually.)

Turns out that npm was installed in the wrong directory so I had to change the “npm config prefix” by running this code:

npm config set prefix /usr/local

Then I reinstalled gulp globally (with the -g param) and it worked properly.

This article is where I found the solution: http://webbb.be/blog/command-not-found-node-npm

You can convert it to a JavaBean if you want using:

 Gson gson = new GsonBuilder().setPrettyPrinting().create();
 gson.fromJson(jsonString, JavaBean.class)

To use JsonObject, which is more flexible, use the following:

String json = "{\"Success\":true,\"Message\":\"Invalid access token.\"}";
JsonParser jsonParser = new JsonParser();
JsonObject jo = (JsonObject)jsonParser.parse(json);
Assert.assertNotNull(jo);
Assert.assertTrue(jo.get("Success").getAsString());

Which is equivalent to the following:

JsonElement jelem = gson.fromJson(json, JsonElement.class);
JsonObject jobj = jelem.getAsJsonObject();

This worked for me, within an ASP.NET MVC3 site where I'd left the framework to setup unobtrusive validation etc., in case it's useful to anyone:

$("form").data("validator").settings.ignore = "";

Taking a leaf from some statistics software, namely SciPy and MATLAB, these just return the smallest most common value, so if two values occur equally often, the smallest of these are returned. Hopefully an example will help:

>>> from scipy.stats import mode

>>> mode([1, 2, 3, 4, 5])
(array([ 1.]), array([ 1.]))

>>> mode([1, 2, 2, 3, 3, 4, 5])
(array([ 2.]), array([ 2.]))

>>> mode([1, 2, 2, -3, -3, 4, 5])
(array([-3.]), array([ 2.]))

Is there any reason why you can 't follow this convention?

end() will provide the last element of an array

$array = array('a' => 'a', 'b' => 'b', 'c' => 'c');
echo end($array); //output: c

$array1 = array('a', 'b', 'c', 'd');
echo end($array1); //output: d

Another way to do this would be to by using map.

>>> a
[1, 2, 3]
>>> b
[4, 5, 6]
>>> for i,j in map(None,a,b):
    ...   print i,j
    ...
1 4
2 5
3 6

One difference in using map compared to zip is, with zip the length of new list is
same as the length of shortest list. For example:

>>> a
[1, 2, 3, 9]
>>> b
[4, 5, 6]
>>> for i,j in zip(a,b):
    ...   print i,j
    ...
1 4
2 5
3 6

Using map on same data:

>>> for i,j in map(None,a,b):
    ...   print i,j
    ...

    1 4
    2 5
    3 6
    9 None

You could use a Scanner

http://download.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

The scanner can also use delimiters other than whitespace. This example reads several items in from a string:

     String input = "1 fish 2 fish red fish blue fish";
     Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
     System.out.println(s.nextInt());
     System.out.println(s.nextInt());
     System.out.println(s.next());
     System.out.println(s.next());
     s.close(); 

prints the following output:

     1
     2
     red
     blue

Better:

if cells(i,1)="" then 
nextEmpty=i: 
exit for

$('#cf_1268591').attr("disabled", true); 

drop down is always read only . what you can do is make it disabled

if you work with a form , the disabled fields does not submit , so use a hidden field to store disabled dropdown value

This error occurs when there are some non ASCII characters in our string and we are performing any operations on that string without proper decoding. This helped me solve my problem. I am reading a CSV file with columns ID,Text and decoding characters in it as below:

train_df = pd.read_csv("Example.csv")
train_data = train_df.values
for i in train_data:
    print("ID :" + i[0])
    text = i[1].decode("utf-8",errors="ignore").strip().lower()
    print("Text: " + text)

I would also like to save a picture. But my problem(?) is that I want to save it from a bitmap that ive drawed.

I made it like this:

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
            switch (item.getItemId()) {
            case R.id.save_sign:      

                myView.save();
                break;

            }
            return false;    

    }

public void save() {
            String filename;
            Date date = new Date(0);
            SimpleDateFormat sdf = new SimpleDateFormat ("yyyyMMddHHmmss");
            filename =  sdf.format(date);

            try{
                 String path = Environment.getExternalStorageDirectory().toString();
                 OutputStream fOut = null;
                 File file = new File(path, "/DCIM/Signatures/"+filename+".jpg");
                 fOut = new FileOutputStream(file);

                 mBitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
                 fOut.flush();
                 fOut.close();

                 MediaStore.Images.Media.insertImage(getContentResolver()
                 ,file.getAbsolutePath(),file.getName(),file.getName());

            }catch (Exception e) {
                e.printStackTrace();
            }

 }

In this context & is causing the function to take stringname by reference. The difference between references and pointers is:

• When you take a reference to a variable, that reference is the variable you referenced. You don't need to dereference it or anything, working with the reference is sematically equal to working with the referenced variable itself.
• NULL is not a valid value to a reference and will result in a compiler error. So generally, if you want to use an output parameter (or a pointer/reference in general) in a C++ function, and passing a null value to that parameter should be allowed, then use a pointer (or smart pointer, preferably). If passing a null value makes no sense for that function, use a reference.
• You cannot 're-seat' a reference. While the value of a pointer can be changed to point at something else, a reference has no similar functionality. Once you take a variable by reference, you are effectively dealing with that variable directly. Just like you can't change the value of a by writing b = 4;. A reference's value is the value of whatever it referenced.

SpahQL is the most promising and well thought out of these, as far as I can tell. I highly recommend checking it out.

Or far simpler than dealing with Spannables manually, since you didn't say that you want the background highlighted, just the text:

String styledText = "This is <font color='red'>simple</font>.";
textView.setText(Html.fromHtml(styledText), TextView.BufferType.SPANNABLE);

Just do:

Stream.of(stream1, stream2, Stream.of(element)).flatMap(identity());

where identity() is a static import of Function.identity().

Concatenating multiple streams into one stream is the same as flattening a stream.

However, unfortunately, for some reason there is no flatten() method on Stream, so you have to use flatMap() with the identity function.

You can do this In the parent component declare:

get self(): ParenComponentClass {
        return this;
    }

In the child component,after include the import of ParenComponentClass, declare:

private _parent: ParenComponentClass ;
@Input() set parent(value: ParenComponentClass ) {
    this._parent = value;
}

get parent(): ParenComponentClass {
    return this._parent;
}

Then in the template of the parent you can do

<childselector [parent]="self"></childselector>

Now from the child you can access public properties and methods of parent using

this.parent

In the past, screen readers and other accessibility software had a difficult time handling tables in an efficient fashion. To some extent, this became handled in screen readers by the reader switching between a "table" mode and a "layout" mode based on what it saw inside the table. This was often wrong, and so the users had to manually switch the mode when navigating through tables. In any case, the large, often highly nested tables were, and to a large extent, are still very difficult to navigate through using a screen reader.

The same is true when divs or other block-level elements are used to recreate tables and are highly nested. The purpose of divs is to be used as a fomating and layout element, and as such, are intended used to hold similar information, and lay it out on the screen for visual users. When a screen reader encounters a page, it often ignores any layout information, both CSS based, as well as html attribute based(This isn't true for all screen readers, but for the most popular ones, like JAWS, Windows Eyes, and Orca for Linux it is).

To this end, tabular data, that is to say data that makes logical sense to be ordered in two or more dimensions, with some sort of headers, is best placed in tables, and use divs to manage the layout of content on the page. (another way to think of what "tabular data" is is to try to draw it in graph form...if you can't, it likely is not best represented in a table)

Finally, with a table-based layout, in order to achieve a fine-grained control of the position of elements on the page, highly nested tables are often used. This has two effects: 1.) Increased code size for each page - Since navigation and common structure is often done with the tables, the same code is sent over the network for each request, whereas a div/css based layout pulls the css file over once, and then uses less wordy divs. 2.) Highly nested tables take much longer for the client's browser to render, leading to slightly slower load times.

In both cases, the increase in "last mile" bandwidth, as well as much faster personal computers mitigates these factors, but none-the-less, they still are existing issues for many sites.

With all of this in mind, as others have said, tables are easier, because they are more grid-oriented, allowing for less thought. If the site in question is not expected to be around long, or will not be maintained, it might make sense to do what is easiest, because it might be the most cost effective. However, if the anticipated userbase might include a substantial portion of handicapped individuals, or if the site will be maintained by others for a long time, spending the time up front to do things in a concise, accessible way may payoff more in the end.

std::string a = "Hello ";
std::string b = "World ";
std::string c = a;
c.append(b);

In newer versions of Qt Creator (Currently using 4.4.1), you can follow these simple steps:
Tools > Options > Environment > Interface

Here you can change the theme to Flat Dark.

It will change the whole Qt Creator theme, not just the editor window.

You could use the ready to use Url Rewrite Filter with a rule like this one:

  <to>/Check_License?Contact_Id=My_Obj_$1</to>
</rule>

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

Why don't you guys try SSEventListener?

You don't need to create any gesture recognizer and separate your logic apart to another method. SSEventListener supports setting listener blocks on a view to listen for single tap gesture, double tap gesture and N-tap gesture if you like, and long press gesture. Setting a single tap gesture listener becomes this way:

[view ss_addTapViewEventListener:^(UITapGestureRecognizer *recognizer) { ... } numberOfTapsRequired:1];

When you want it to validate (in XML/XHTML - thanks, Loren Segal).

To use AUTO_INCREMENT you need to deifne column as INT or floating-point types, not CHAR.

AUTO_INCREMENT use only unsigned value, so it's good to use UNSIGNED as well;

CREATE TABLE discussion_topics (

     topic_id INT NOT NULL unsigned AUTO_INCREMENT,
     project_id char(36) NOT NULL,
     topic_subject VARCHAR(255) NOT NULL,
     topic_content TEXT default NULL,
     date_created DATETIME NOT NULL,
     date_last_post DATETIME NOT NULL,
     created_by_user_id char(36) NOT NULL,
     last_post_user_id char(36) NOT NULL,
     posts_count char(36) default NULL,
     PRIMARY KEY (topic_id) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

from this link:

you can use rstrip() method. Example

mystring = "hello\n"    
print(mystring.rstrip('\n'))

This is an extremely broad scope question, and a lot of the pros/cons will be contextual to the situation.

In all cases, these storage mechanisms will be specific to an individual browser on an individual computer/device. Any requirement to store data on an ongoing basis across sessions will need to involve your application server side - most likely using a database, but possibly XML or a text/CSV file.

localStorage, sessionStorage, and cookies are all client storage solutions. Session data is held on the server where it remains under your direct control.

localStorage and sessionStorage

localStorage and sessionStorage are relatively new APIs (meaning, not all legacy browsers will support them) and are near identical (both in APIs and capabilities) with the sole exception of persistence. sessionStorage (as the name suggests) is only available for the duration of the browser session (and is deleted when the tab or window is closed) - it does, however, survive page reloads (source DOM Storage guide - Mozilla Developer Network).

Clearly, if the data you are storing needs to be available on an ongoing basis then localStorage is preferable to sessionStorage - although you should note both can be cleared by the user so you should not rely on the continuing existence of data in either case.

localStorage and sessionStorage are perfect for persisting non-sensitive data needed within client scripts between pages (for example: preferences, scores in games). The data stored in localStorage and sessionStorage can easily be read or changed from within the client/browser so should not be relied upon for storage of sensitive or security-related data within applications.

Cookies

This is also true for cookies, these can be trivially tampered with by the user, and data can also be read from them in plain text - so if you are wanting to store sensitive data then the session is really your only option. If you are not using SSL, cookie information can also be intercepted in transit, especially on an open wifi.

On the positive side cookies can have a degree of protection applied from security risks like Cross-Site Scripting (XSS)/Script injection by setting an HTTP only flag which means modern (supporting) browsers will prevent access to the cookies and values from JavaScript (this will also prevent your own, legitimate, JavaScript from accessing them). This is especially important with authentication cookies, which are used to store a token containing details of the user who is logged on - if you have a copy of that cookie then for all intents and purposes you become that user as far as the web application is concerned, and have the same access to data and functionality the user has.

As cookies are used for authentication purposes and persistence of user data, all cookies valid for a page are sent from the browser to the server for every request to the same domain - this includes the original page request, any subsequent Ajax requests, all images, stylesheets, scripts, and fonts. For this reason, cookies should not be used to store large amounts of information. The browser may also impose limits on the size of information that can be stored in cookies. Typically cookies are used to store identifying tokens for authentication, session, and advertising tracking. The tokens are typically not human readable information in and of themselves, but encrypted identifiers linked to your application or database.

localStorage vs. sessionStorage vs. Cookies

In terms of capabilities, cookies, sessionStorage, and localStorage only allow you to store strings - it is possible to implicitly convert primitive values when setting (these will need to be converted back to use them as their type after reading) but not Objects or Arrays (it is possible to JSON serialise them to store them using the APIs). Session storage will generally allow you to store any primitives or objects supported by your Server Side language/framework.

Client-side vs. Server-side

As HTTP is a stateless protocol - web applications have no way of identifying a user from previous visits on returning to the web site - session data usually relies on a cookie token to identify the user for repeat visits (although rarely URL parameters may be used for the same purpose). Data will usually have a sliding expiry time (renewed each time the user visits), and depending on your server/framework data will either be stored in-process (meaning data will be lost if the web server crashes or is restarted) or externally in a state server or database. This is also necessary when using a web-farm (more than one server for a given website).

As session data is completely controlled by your application (server side) it is the best place for anything sensitive or secure in nature.

The obvious disadvantage of server-side data is scalability - server resources are required for each user for the duration of the session, and that any data needed client side must be sent with each request. As the server has no way of knowing if a user navigates to another site or closes their browser, session data must expire after a given time to avoid all server resources being taken up by abandoned sessions. When using session data you should, therefore, be aware of the possibility that data will have expired and been lost, especially on pages with long forms. It will also be lost if the user deletes their cookies or switches browsers/devices.

Some web frameworks/developers use hidden HTML inputs to persist data from one page of a form to another to avoid session expiration.

localStorage, sessionStorage, and cookies are all subject to "same-origin" rules which means browsers should prevent access to the data except the domain that set the information to start with.

While you can do OO in C (e.g. by adding a theType *this first parameter to methods, and manually handling something like vtables for polymorphism) this is never particularly satisfactory as a design, and will look ugly (even with some pre-processor hacks).

I would suggest at least looking at a re-design to compare how this would work out.

Overall a lot depends on the answer to the key question: if you have working C++ code, why do you want C instead?

Not sure about the Java parsing, but that's ISO8601: http://en.wikipedia.org/wiki/ISO_8601

In Java
Integer/Integer = Integer
Integer/Double = Double//Either of numerator or denominator must be floating point number
1/10 = 0
1.0/10 = 0.1
1/10.0 = 0.1

Just type cast either of them.

Please try like this : git clone --single-branch --branch <branchname> <url>

replace <branchname> with your branch and <url> with your url.

url will be like http://[email protected]:portno/yourrepo.git.

Before understanding next, you need to have a little idea of Request-Response cycle in node though not much in detail. It starts with you making an HTTP request for a particular resource and it ends when you send a response back to the user i.e. when you encounter something like res.send(‘Hello World’);

let’s have a look at a very simple example.

app.get('/hello', function (req, res, next) {
  res.send('USER')
})

Here we do not need next(), because resp.send will end the cycle and hand over the control back to the route middleware.

Now let’s take a look at another example.

app.get('/hello', function (req, res, next) {
  res.send("Hello World !!!!");
});

app.get('/hello', function (req, res, next) {
  res.send("Hello Planet !!!!");
});

Here we have 2 middleware functions for the same path. But you always gonna get the response from the first one. Because that is mounted first in the middleware stack and res.send will end the cycle.

But what if we always do not want the “Hello World !!!!” response back. For some conditions we may want the "Hello Planet !!!!" response. Let’s modify the above code and see what happens.

app.get('/hello', function (req, res, next) {
  if(some condition){
    next();
    return;
  }
  res.send("Hello World !!!!");  
});

app.get('/hello', function (req, res, next) {
  res.send("Hello Planet !!!!");
});

What’s the next doing here. And yes you might have gusses. It’s gonna skip the first middleware function if the condition is true and invoke the next middleware function and you will have the "Hello Planet !!!!" response.

So, next pass the control to the next function in the middleware stack.

What if the first middleware function does not send back any response but do execute a piece of logic and then you get the response back from second middleware function.

Something like below:-

app.get('/hello', function (req, res, next) {
  // Your piece of logic
  next();
});

app.get('/hello', function (req, res, next) {
  res.send("Hello !!!!");
});

In this case you need both the middleware functions to be invoked. So, the only way you reach the second middleware function is by calling next();

What if you do not make a call to next. Do not expect the second middleware function to get invoked automatically. After invoking the first function your request will be left hanging. The second function will never get invoked and you will not get back the response.

TL;DR

git show <commit>

Show

To show what a commit did with stats:

git show <commit> --stat

Log

To show commit log with differences introduced for each commit in a range:

git log -p <commit1> <commit2>

What is <commit>?

Each commit has a unique id we reference here as <commit>. The unique id is an SHA-1 hash – a checksum of the content you’re storing plus a header. #TMI

If you don't know your <commit>:

1. git log to view the commit history

2. Find the commit you care about.

In my case, I added a new record manually saved and again through shell tried to add new record this time it works perfectly check it out.

In [7]: from main.models import Flight

In [8]: f = Flight(origin="Florida", destination="Alaska", duration=10)

In [9]: f.save()

In [10]: Flight.objects.all() 
Out[10]: <QuerySet [<Flight: Flight object (1)>, <Flight: Flight object (2)>, <Flight: Flight object (3)>, <Flight: Flight object (4)>]>

The quick and dirty way, you can view the available environment variables from the below link.

http://localhost:8080/env-vars.html/

Just replace localhost with your Jenkins hostname, if its different

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

To get the week number for a date in North America I do like this:

function week_number($n)
{
    $w = date('w', $n);
    return 1 + date('z', $n + (6 - $w) * 24 * 3600) / 7;
}

$n = strtotime('2022-12-27');
printf("%s: %d\n", date('D Y-m-d', $n), week_number($n));

and get:

Tue 2022-12-27: 53

The below programme will help you drop duplicates on whole , or if you want to drop duplicates based on certain columns , you can even do that:

import org.apache.spark.sql.SparkSession

object DropDuplicates {
def main(args: Array[String]) {
val spark =
  SparkSession.builder()
    .appName("DataFrame-DropDuplicates")
    .master("local[4]")
    .getOrCreate()

import spark.implicits._

// create an RDD of tuples with some data
val custs = Seq(
  (1, "Widget Co", 120000.00, 0.00, "AZ"),
  (2, "Acme Widgets", 410500.00, 500.00, "CA"),
  (3, "Widgetry", 410500.00, 200.00, "CA"),
  (4, "Widgets R Us", 410500.00, 0.0, "CA"),
  (3, "Widgetry", 410500.00, 200.00, "CA"),
  (5, "Ye Olde Widgete", 500.00, 0.0, "MA"),
  (6, "Widget Co", 12000.00, 10.00, "AZ")
)
val customerRows = spark.sparkContext.parallelize(custs, 4)

// convert RDD of tuples to DataFrame by supplying column names
val customerDF = customerRows.toDF("id", "name", "sales", "discount", "state")

println("*** Here's the whole DataFrame with duplicates")

customerDF.printSchema()

customerDF.show()

// drop fully identical rows
val withoutDuplicates = customerDF.dropDuplicates()

println("*** Now without duplicates")

withoutDuplicates.show()

// drop fully identical rows
val withoutPartials = customerDF.dropDuplicates(Seq("name", "state"))

println("*** Now without partial duplicates too")

withoutPartials.show()

 }
 }

HTTP transaction, basic access authentication, is not suitable for RBAC, because basic access authentication uses the encrypted username:password every time to identify, while what is needed in RBAC is the Role the user wants to use for a specific call. RBAC does not validate permissions on username, but on roles.

You could tric around to concatenate like this: usernameRole:password, but this is bad practice, and it is also inefficient because when a user has more roles, the authentication engine would need to test all roles in concatenation, and that every call again. This would destroy one of the biggest technical advantages of RBAC, namely a very quick authorization-test.

So that problem cannot be solved using basic access authentication.

To solve this problem, session-maintaining is necessary, and that seems, according to some answers, in contradiction with REST.

That is what I like about the answer that REST should not be treated as a religion. In complex business cases, in healthcare, for example, RBAC is absolutely common and necessary. And it would be a pity if they would not be allowed to use REST because all REST-tools designers would treat REST as a religion.

For me there are not many ways to maintain a session over HTTP. One can use cookies, with a sessionId, or a header with a sessionId.

If someone has another idea I will be glad to hear it.

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

You can use always stream writer.It will erase old data and append new one each time.

using (StreamWriter sw = new StreamWriter(filePath))
{                            
    getNumberOfControls(frm1,sw);
}

For me this worked like below -

I had sheet name references in formula for the same sheet. When I removed current sheet name from the formula and sorted it worked correctly.

Since Vagrant 1.1 customize option is getting VirtualBox-specific.

The modern way to do it is:

config.vm.provider :virtualbox do |vb|
  vb.customize ["modifyvm", :id, "--memory", "256"]
end

Horrible to look for this failure:

Copy .dll to here:

\Program Files\Notepad++\plugins --> put it here

Restart the notepad++

and now you are able to use the copy commands!!!

You should use some background image to your radio buttons and flip it with another image on change

.radio {
    background: url(customButton.png) no-repeat;
}

I found the reason why the connection was not working, it was because the connection was trying to connect to port 8888, when it needed to connect to port 8889.

$conn = new PDO("mysql:host=$servername;port=8889;dbname=AppDatabase", $username, $password); 

This fixed the problem, although changing the server name to localhost still gives the error.

Connection failed: SQLSTATE[HY000] [2002] No such file or directory

But it connects successfully when the IP address is entered for the server name.

Microsoft.AspNetCore.All: v2.0.3 | Dapper: v1.50.2

I am not sure if I am using the best practices correctly or not, but I am doing it this way, in order to handle multiple connection strings.

It's easy if you have only 1 connection string

Startup.cs

using System.Data;
using System.Data.SqlClient;

namespace DL.SO.Project.Web.UI
{
    public class Startup
    {
        public IConfiguration Configuration { get; private set; }

        // ......

        public void ConfigureServices(IServiceCollection services)
        {
            // Read the connection string from appsettings.
            string dbConnectionString = this.Configuration.GetConnectionString("dbConnection1");

            // Inject IDbConnection, with implementation from SqlConnection class.
            services.AddTransient<IDbConnection>((sp) => new SqlConnection(dbConnectionString));

            // Register your regular repositories
            services.AddScoped<IDiameterRepository, DiameterRepository>();

            // ......
        }
    }
}

DiameterRepository.cs

using Dapper;
using System.Data;

namespace DL.SO.Project.Persistence.Dapper.Repositories
{
    public class DiameterRepository : IDiameterRepository
    {
        private readonly IDbConnection _dbConnection;

        public DiameterRepository(IDbConnection dbConnection)
        {
            _dbConnection = dbConnection;
        }

        public IEnumerable<Diameter> GetAll()
        {
            const string sql = @"SELECT * FROM TABLE";

            // No need to use using statement. Dapper will automatically
            // open, close and dispose the connection for you.
            return _dbConnection.Query<Diameter>(sql);
        }

        // ......
    }
}

Problems if you have more than 1 connection string

Since Dapper utilizes IDbConnection, you need to think of a way to differentiate different database connections.

I tried to create multiple interfaces, 'inherited' from IDbConnection, corresponding to different database connections, and inject SqlConnection with different database connection strings on Startup.

That failed because SqlConnection inherits from DbConnection, and DbConnection inplements not only IDbConnection but also Component class. So your custom interfaces won't be able to use just the SqlConnection implenentation.

I also tried to create my own DbConnection class that takes different connection string. That's too complicated because you have to implement all the methods from DbConnection class. You lost the help from SqlConnection.

What I end up doing

1. During Startup, I loaded all connection string values into a dictionary. I also created an enum for all the database connection names to avoid magic strings.
2. I injected the dictionary as Singleton.
3. Instead of injecting IDbConnection, I created IDbConnectionFactory and injected that as Transient for all repositories. Now all repositories take IDbConnectionFactory instead of IDbConnection.
4. When to pick the right connection? In the constructor of all repositories! To make things clean, I created repository base classes and have the repositories inherit from the base classes. The right connection string selection can happen in the base classes.

DatabaseConnectionName.cs

namespace DL.SO.Project.Domain.Repositories
{
    public enum DatabaseConnectionName
    {
        Connection1,
        Connection2
    }
}

IDbConnectionFactory.cs

using System.Data;

namespace DL.SO.Project.Domain.Repositories
{
    public interface IDbConnectionFactory
    {
        IDbConnection CreateDbConnection(DatabaseConnectionName connectionName);
    }
}

DapperDbConenctionFactory - my own factory implementation

namespace DL.SO.Project.Persistence.Dapper
{
    public class DapperDbConnectionFactory : IDbConnectionFactory
    {
        private readonly IDictionary<DatabaseConnectionName, string> _connectionDict;

        public DapperDbConnectionFactory(IDictionary<DatabaseConnectionName, string> connectionDict)
        {
            _connectionDict = connectionDict;
        }

        public IDbConnection CreateDbConnection(DatabaseConnectionName connectionName)
        {
            string connectionString = null;
            if (_connectDict.TryGetValue(connectionName, out connectionString))
            {
                return new SqlConnection(connectionString);
            }

            throw new ArgumentNullException();
        }
    }
}

Startup.cs

namespace DL.SO.Project.Web.UI
{
    public class Startup
    {
        // ......

        public void ConfigureServices(IServiceCollection services)
        {
            var connectionDict = new Dictionary<DatabaseConnectionName, string>
            {
                { DatabaseConnectionName.Connection1, this.Configuration.GetConnectionString("dbConnection1") },
                { DatabaseConnectionName.Connection2, this.Configuration.GetConnectionString("dbConnection2") }
            };

            // Inject this dict
            services.AddSingleton<IDictionary<DatabaseConnectionName, string>>(connectionDict);

            // Inject the factory
            services.AddTransient<IDbConnectionFactory, DapperDbConnectionFactory>();

            // Register your regular repositories
            services.AddScoped<IDiameterRepository, DiameterRepository>();

            // ......
        }
    }
}

DiameterRepository.cs

using Dapper;
using System.Data;

namespace DL.SO.Project.Persistence.Dapper.Repositories
{
    // Move the responsibility of picking the right connection string
    //   into an abstract base class so that I don't have to duplicate
    //   the right connection selection code in each repository.
    public class DiameterRepository : DbConnection1RepositoryBase, IDiameterRepository
    {
        public DiameterRepository(IDbConnectionFactory dbConnectionFactory)
            : base(dbConnectionFactory) { }

        public IEnumerable<Diameter> GetAll()
        {
            const string sql = @"SELECT * FROM TABLE";

            // No need to use using statement. Dapper will automatically
            // open, close and dispose the connection for you.
            return base.DbConnection.Query<Diameter>(sql);
        }

        // ......
    }
}

DbConnection1RepositoryBase.cs

using System.Data;
using DL.SO.Project.Domain.Repositories;

namespace DL.SO.Project.Persistence.Dapper
{
    public abstract class DbConnection1RepositoryBase
    {
        public IDbConnection DbConnection { get; private set; }

        public DbConnection1RepositoryBase(IDbConnectionFactory dbConnectionFactory)
        {
            // Now it's the time to pick the right connection string!
            // Enum is used. No magic string!
            this.DbConnection = dbConnectionFactory.CreateDbConnection(DatabaseConnectionName.Connection1);
        }
    }
}

Then for other repositories that need to talk to the other connections, you can create a different repository base class for them.

using System.Data;
using DL.SO.Project.Domain.Repositories;

namespace DL.SO.Project.Persistence.Dapper
{
    public abstract class DbConnection2RepositoryBase
    {
        public IDbConnection DbConnection { get; private set; }

        public DbConnection2RepositoryBase(IDbConnectionFactory dbConnectionFactory)
        {
            this.DbConnection = dbConnectionFactory.CreateDbConnection(DatabaseConnectionName.Connection2);
        }
    }
}

using Dapper;
using System.Data;

namespace DL.SO.Project.Persistence.Dapper.Repositories
{
    public class ParameterRepository : DbConnection2RepositoryBase, IParameterRepository
    {
        public ParameterRepository (IDbConnectionFactory dbConnectionFactory)
            : base(dbConnectionFactory) { }

        public IEnumerable<Parameter> GetAll()
        {
            const string sql = @"SELECT * FROM TABLE";
            return base.DbConnection.Query<Parameter>(sql);
        }

        // ......
    }
}

Hope all these help.

• Make sure your images are accurate size according to Apple guidelines.
• Make sure, You will select only one option , either launch screen file or Launch Image Source. You can find these two options in Project build settings -> General

My suggestion to you is to select Launch Image Source as Image.Assets. Create splash image assets there in Image.assests folder.

If you only need to support certain modern browsers then you can now use:

navigator.languages

which returns an array of the user's language preferences in the order specified by the user.

There is no way to know unless the particular company reveals the info. The best you can do is find a few companies that are sharing and then extrapolate based on app ranking (which is available publicly). The best you'll get is a ball park estimate.

Simplest way to do so is to read the size of a "querySnapshot".

db.collection("cities").get().then(function(querySnapshot) {      
    console.log(querySnapshot.size); 
});

You can also read the length of the docs array inside "querySnapshot".

querySnapshot.docs.length;

Or if a "querySnapshot" is empty by reading the empty value, which will return a boolean value.

querySnapshot.empty;

pickling is recursive, not sequential. Thus, to pickle a list, pickle will start to pickle the containing list, then pickle the first element… diving into the first element and pickling dependencies and sub-elements until the first element is serialized. Then moves on to the next element of the list, and so on, until it finally finishes the list and finishes serializing the enclosing list. In short, it's hard to treat a recursive pickle as sequential, except for some special cases. It's better to use a smarter pattern on your dump, if you want to load in a special way.

The most common pickle, it to pickle everything with a single dump to a file -- but then you have to load everything at once with a single load. However, if you open a file handle and do multiple dump calls (e.g. one for each element of the list, or a tuple of selected elements), then your load will mirror that… you open the file handle and do multiple load calls until you have all the list elements and can reconstruct the list. It's still not easy to selectively load only certain list elements, however. To do that, you'd probably have to store your list elements as a dict (with the index of the element or chunk as the key) using a package like klepto, which can break up a pickled dict into several files transparently, and enables easy loading of specific elements.

Saving and loading multiple objects in pickle file?

I'm recently doing a project and using collections.Counter.(Which tortured me).

The Counter in collections have a very very bad performance in my opinion. It's just a class wrapping dict().

What's worse, If you use cProfile to profile its method, you should see a lot of '__missing__' and '__instancecheck__' stuff wasting the whole time.

Be careful using its most_common(), because everytime it would invoke a sort which makes it extremely slow. and if you use most_common(x), it will invoke a heap sort, which is also slow.

Btw, numpy's bincount also have a problem: if you use np.bincount([1,2,4000000]), you will get an array with 4000000 elements.

A Stacked bar chart should suffice:

Setup data as follows

Name    Start       End         Duration (End - Start)
Fred    1/01/1981   1/06/1985    1612   
Bill    1/07/1985   1/11/2000    5602  
Joe     1/01/1980   1/12/2001    8005  
Jim     1/03/1999   1/01/2000    306  

1. Plot Start and Duration as a stacked bar chart
2. Set the X-Axis minimum to the desired start date
3. Set the Fill Colour of thestart range to no fill
4. Set the Fill of individual bars to suit

I got exactly the same error in Windows 8 while trying to export decision tree digraph using tree.export_graphviz! Then I installed GraphViz from this link. And then I followed the below steps which resolved my issue:

• Right click on My PC >> click on "Change Settings" under "Computer name, domain, and workgroup settings"
• It will open the System Properties window; Goto 'Advanced' tab >> click on 'Environment Variables' >> Under "System Variables" >> select 'Path' and click on 'Edit' >> In 'Variable Value' field, put a semicolon (;) at the end of existing value and then include the path of its installation folder (e.g. ;C:\Program Files (x86)\Graphviz2.38\bin) >> Click on 'Ok' >> 'Ok' >> 'Ok'
• Restart your PC as environment variables are changed

With bootstrap3-typeahead, I made it to work with the following code:

<input id="typeahead-input" type="text" data-provide="typeahead" />

<script type="text/javascript">
jQuery(document).ready(function() {
    $('#typeahead-input').typeahead({
        source: function (query, process) {
            return $.get('search?q=' + query, function (data) {
                return process(data.search_results);
            });
        }
    });
})
</script>

The backend provides search service under the search GET endpoint, receiving the query in the q parameter, and returns a JSON in the format { 'search_results': ['resultA', 'resultB', ... ] }. The elements of the search_resultsarray are displayed in the typeahead input.

The reason it is only a suggestion is that you could quite easily write a print function that ignored the options value. The built-in printing and formatting functions do use the options value as a default.

As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles.

Mathematica or Maple will allow you to give as many decimal places as your heart desires.

EDIT:
It might be useful to think about the difference between decimal places and significant figures. If you are doing statistical tests that rely on differences beyond the 15th significant figure, then your analysis is almost certainly junk.

On the other hand, if you are just dealing with very small numbers, that is less of a problem, since R can handle number as small as .Machine$double.xmin (usually 2e-308).

Compare these two analyses.

x1 <- rnorm(50, 1, 1e-15)
y1 <- rnorm(50, 1 + 1e-15, 1e-15)
t.test(x1, y1)  #Should throw an error

x2 <- rnorm(50, 0, 1e-15)
y2 <- rnorm(50, 1e-15, 1e-15)
t.test(x2, y2)  #ok

In the first case, differences between numbers only occur after many significant figures, so the data are "nearly constant". In the second case, Although the size of the differences between numbers are the same, compared to the magnitude of the numbers themselves they are large.

As mentioned by e3bo, you can use multiple-precision floating point numbers using the Rmpfr package.

mpfr("3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825")

These are slower and more memory intensive to use than regular (double precision) numeric vectors, but can be useful if you have a poorly conditioned problem or unstable algorithm.

I realize this question is ancient and there is an accepted and an alternate answer. I also realize that my answer will only answer half of the question, but for anyone wanting to round to the nearest minute and still have a datetime compatible value using only a single function:

CAST(YourValueHere as smalldatetime);

For hours or seconds, use Jeff Ogata's answer (the accepted answer) above.

As others have said, simply restarting the terminal after you've made changes should reset and changes you've made to your ~/.zshrc file. For instance after adding function to open visual studio:

function code {  
    if [[ $# = 0 ]]
    then
        open -a "Visual Studio Code"
    else
        local argPath="$1"
        [[ $1 = /* ]] && argPath="$1" || argPath="$PWD/${1#./}"
        open -a "Visual Studio Code" "$argPath"
    fi
}

I was able to use the keyword code to open the program from the command line.

from Jackson 2.7.x+ there is a way to annotate the member variable itself:

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

I got this error because of a missing return statement.

In my experience, most probably its happened with jquery version(using multiple version) conflicts, for sort out the issue we can use a no-conflict method like below.

jQuery.noConflict();
(function( $ ) {
  $(function() {
    // More code using $ as alias to jQuery
    $('button').click(function(){
        $('#modalID').modal('show');
    });
  });
})(jQuery);

In[1]: def myfunc(a=1, b=2):
In[2]:    print(a, b)

In[3]: mydict = {'a': 100, 'b': 200}

In[4]: myfunc(**mydict)
100 200

A few extra details that might be helpful to know (questions I had after reading this and went and tested):

1. The function can have parameters that are not included in the dictionary
2. You can not override a parameter that is already in the dictionary
3. The dictionary can not have parameters that aren't in the function.

Examples:

Number 1: The function can have parameters that are not included in the dictionary

In[5]: mydict = {'a': 100}
In[6]: myfunc(**mydict)
100 2

Number 2: You can not override a parameter that is already in the dictionary

In[7]: mydict = {'a': 100, 'b': 200}
In[8]: myfunc(a=3, **mydict)

TypeError: myfunc() got multiple values for keyword argument 'a'

Number 3: The dictionary can not have parameters that aren't in the function.

In[9]:  mydict = {'a': 100, 'b': 200, 'c': 300}
In[10]: myfunc(**mydict)

TypeError: myfunc() got an unexpected keyword argument 'c'

As requested in comments, a solution to Number 3 is to filter the dictionary based on the keyword arguments available in the function:

In[11]: import inspect
In[12]: mydict = {'a': 100, 'b': 200, 'c': 300}
In[13]: filtered_mydict = {k: v for k, v in mydict.items() if k in [p.name for p in inspect.signature(myfunc).parameters.values()]}
In[14]: myfunc(**filtered_mydict)
100 200

Another option is to accept (and ignore) additional kwargs in your function:

In[15]: def myfunc2(a=None, **kwargs):
In[16]:    print(a)

In[17]: mydict = {'a': 100, 'b': 200, 'c': 300}

In[18]: myfunc2(**mydict)
100

Notice further than you can use positional arguments and lists or tuples in effectively the same way as kwargs, here's a more advanced example incorporating both positional and keyword args:

In[19]: def myfunc3(a, *posargs, b=2, **kwargs):
In[20]:    print(a, b)
In[21]:    print(posargs)
In[22]:    print(kwargs)

In[23]: mylist = [10, 20, 30]
In[24]: mydict = {'b': 200, 'c': 300}

In[25]: myfunc3(*mylist, **mydict)
10 200
(20, 30)
{'c': 300}

We can use params, new feature of the UI-Router:

API Reference / ui.router.state / $stateProvider

params A map which optionally configures parameters declared in the url, or defines additional non-url parameters. For each parameter being configured, add a configuration object keyed to the name of the parameter.

See the part: "...or defines additional non-url parameters..."

So the state def would be:

$stateProvider
  .state('home', {
    url: "/home",
    templateUrl: 'tpl.html',
    params: { hiddenOne: null, }
  })

Few examples form the doc mentioned above:

// define a parameter's default value
params: {
  param1: { value: "defaultValue" }
}
// shorthand default values
params: {
  param1: "defaultValue",
  param2: "param2Default"
}

// param will be array []
params: {
  param1: { array: true }
}

// handling the default value in url:
params: {
  param1: {
    value: "defaultId",
    squash: true
} }
// squash "defaultValue" to "~"
params: {
  param1: {
    value: "defaultValue",
    squash: "~"
  } }

EXTEND - working example: http://plnkr.co/edit/inFhDmP42AQyeUBmyIVl?p=info

Here is an example of a state definition:

 $stateProvider
  .state('home', {
      url: "/home",
      params : { veryLongParamHome: null, },
      ...
  })
  .state('parent', {
      url: "/parent",
      params : { veryLongParamParent: null, },
      ...
  })
  .state('parent.child', { 
      url: "/child",
      params : { veryLongParamChild: null, },
      ...
  })

This could be a call using ui-sref:

<a ui-sref="home({veryLongParamHome:'Home--f8d218ae-d998-4aa4-94ee-f27144a21238'
  })">home</a>

<a ui-sref="parent({ 
    veryLongParamParent:'Parent--2852f22c-dc85-41af-9064-d365bc4fc822'
  })">parent</a>

<a ui-sref="parent.child({
    veryLongParamParent:'Parent--0b2a585f-fcef-4462-b656-544e4575fca5',  
    veryLongParamChild:'Child--f8d218ae-d998-4aa4-94ee-f27144a61238'
  })">parent.child</a>

Check the example here

It is also worth to mention, that if you DO NOT intent to modify the values of the list, it is possible (and better) to use the const_iterator, as follows:

for (std::list<Student>::const_iterator it = data.begin(); it != data.end(); ++it){
    // do whatever you wish but don't modify the list elements
    std::cout << it->name;
}

If you want to write all in one line try

new Select (driver.findElement(By.id("designation"))).selectByVisibleText("Programmer ");

To see your log in SQL Developer then press:

CTRL+SHIFT + L (or CTRL + CMD + L on macOS)

or

View -> Log

or by using mysql query

show errors;

select *
into existing table database..existingtable
from database..othertables....

If you have used select * into tablename from other tablenames already, next time, to append, you say select * into existing table tablename from other tablenames

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

Should be xpath with not contains() method, //production[not(contains(category,'business'))]

Press ESC to make sure you are out of the edit mode and then type:

:wq

Within the push method of hashHistory, you can specify your query parameters. For instance,

history.push({
  pathname: '/dresses',
  search: '?color=blue'
})

or

history.push('/dresses?color=blue')

You can check out this repository for additional examples on using history

You have no combinator (space, >, +...) so no children will get involved, ever.

However, you could avoid the need for jQuery by using an ID and getElementById, or you could use the old getElementsByName("frmSave")[0] or the even older document.forms['frmSave']. jQuery is unnecessary here.

From the documentation:

If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

A leading slash matches the beginning of the pathname. For example, "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".

So you should add the following line to your root .gitignore:

/config.php

Check out this plugin:

moment-countdown

moment-countdown is a tiny moment.js plugin that integrates with Countdown.js. The file is here.

How it works?

//from then until now
moment("1982-5-25").countdown().toString(); //=> '30 years, 10 months, 14 days, 1 hour, 8 minutes, and 14 seconds'

//accepts a moment, JS Date, or anything parsable by the Date constructor
moment("1955-8-21").countdown("1982-5-25").toString(); //=> '26 years, 9 months, and 4 days'

//also works with the args flipped, like diff()
moment("1982-5-25").countdown("1955-8-21").toString(); //=> '26 years, 9 months, and 4 days'

//accepts all of countdown's options
moment().countdown("1982-5-25", countdown.MONTHS|countdown.WEEKS, NaN, 2).toString(); //=> '370 months, and 2.01 weeks'

I don't think it provides a multi-hop wireless packet routing environment. However you can try to integrate a simple routing mechanism. Just check out Wi-Share to get an idea how it can be done.

It basically overrides the method canScrollHorizontally to disable swiping by finger. Howsoever setCurrentItem still works.

You can't insert the values into timestamp column explicitly. It is auto-generated. Do not use this column in your insert statement. Refer http://msdn.microsoft.com/en-us/library/ms182776(SQL.90).aspx for more details.

You could use a datetime instead of a timestamp like this:

create table demo (
    ts datetime
)

insert into demo select current_timestamp

select ts from demo

Returns:

2014-04-04 09:20:01.153

With regex:

re.sub(r'^(.{75}).*$', '\g<1>...', data)

Long strings are truncated:

>>> data="11111111112222222222333333333344444444445555555555666666666677777777778888888888"
>>> re.sub(r'^(.{75}).*$', '\g<1>...', data)
'111111111122222222223333333333444444444455555555556666666666777777777788888...'

Shorter strings never get truncated:

>>> data="11111111112222222222333333"
>>> re.sub(r'^(.{75}).*$', '\g<1>...', data)
'11111111112222222222333333'

This way, you can also "cut" the middle part of the string, which is nicer in some cases:

re.sub(r'^(.{5}).*(.{5})$', '\g<1>...\g<2>', data)

>>> data="11111111112222222222333333333344444444445555555555666666666677777777778888888888"
>>> re.sub(r'^(.{5}).*(.{5})$', '\g<1>...\g<2>', data)
'11111...88888'

don't forget to close and start the terminal window again ;)

(at least if you want to check "npm --version" in the terminal)

sudo npm install npm -g

that did the trick for me, too

Just drop

<script>
myfunction();
</script>

in the body where you want it to be called, understanding that when the page loads and the browser reaches that point, that's when the call will occur.

When running in a CI script, you will have trouble with imperative commands as create raises an error if the resource already exists.

What you can do is applying (declarative pattern) the output of your imperative command, by using --dry-run=true and -o yaml options:

kubectl create whatever --dry-run=true -o yaml | kubectl apply -f -

The command above will not raise an error if the resource already exists (and will update the resource if needed).

This is very useful in some cases where you cannot use the declarative pattern (for instance when creating a docker-registry secret).

I would go with Ryan's answer if you really want to do this.

In general on a *nix environment, you always want to err on giving away as little permissions as possible.

9 times out of 10, 755 is the ideal permission for this - as the only user with the ability to modify the files will be the webserver. Change this to 775 with your ftp user in a group if you REALLY need to change this.

Since you're new to php by your own admission, here's a helpful link for improving the security of your upload service: move_uploaded_file

No, but another great alternative is having the method use a generic template class for optional parameters as follows:

public class OptionalOut<Type>
{
    public Type Result { get; set; }
}

Then you can use it as follows:

public string foo(string value, OptionalOut<int> outResult = null)
{
    // .. do something

    if (outResult != null) {
        outResult.Result = 100;
    }

    return value;
}

public void bar ()
{
    string str = "bar";

    string result;
    OptionalOut<int> optional = new OptionalOut<int> ();

    // example: call without the optional out parameter
    result = foo (str);
    Console.WriteLine ("Output was {0} with no optional value used", result);

    // example: call it with optional parameter
    result = foo (str, optional);
    Console.WriteLine ("Output was {0} with optional value of {1}", result, optional.Result);

    // example: call it with named optional parameter
    foo (str, outResult: optional);
    Console.WriteLine ("Output was {0} with optional value of {1}", result, optional.Result);
}

+1 for VisualSVN being better than AnkhSVN, having tried both, and +1 for the FogBugz Add-in.

The old tried and true

mkdir /tmp/qq >/dev/null 2>&1

will do what you want with none of the race conditions many of the other solutions have.

Sometimes the simplest (and ugliest) solutions are the best.

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

Use zip(*list):

>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]

The zip() function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l you apply all tuples in l as separate arguments to the zip() function, so zip() pairs up 1 with 3 with 8 first, then 2 with 4 and 9. Those happen to correspond nicely with the columns, or the transposition of l.

zip() produces tuples; if you must have mutable list objects, just map() the tuples to lists or use a list comprehension to produce a list of lists:

map(list, zip(*l))          # keep it a generator
[list(t) for t in zip(*l)]  # consume the zip generator into a list of lists

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

You can simply center the image and text in the parent tag by setting

div {
     text-align: center;
}

vertical center the img and span

img {
     vertical-align:middle;
}
span {
     vertical-align:middle;
}

You can just add second set below, and one thing to mention is that h4 has block display attribute, so you might want to set

h4 {
    display: inline-block
}

to set the h4 "inline".

The full example is shown here.

<div id="photo" style="text-align: center">_x000D_
  <img style="vertical-align:middle" src="https://via.placeholder.com/22x22" alt="">_x000D_
  <span style="vertical-align:middle">Take a photo</span>_x000D_
</div>

The basic intrinsic types (e.g. byte, int, string, and arrays) will be serialized automatically by WCF. Custom classes, like your UploadedFile, won't be.

So, a silly question (but I have to ask it...): is UploadedFile marked as a [DataContract]? If not, you'll need to make sure that it is, and that each of the members in the class that you want to send are marked with [DataMember].

Unlike remoting, where marking a class with [XmlSerializable] allowed you to serialize the whole class without bothering to mark the members that you wanted serialized, WCF needs you to mark up each member. (I believe this is changing in .NET 3.5 SP1...)

A tremendous resource for WCF development is what we know in our shop as "the fish book": Programming WCF Services by Juval Lowy. Unlike some of the other WCF books around, which are a bit dry and academic, this one takes a practical approach to building WCF services and is actually useful. Thoroughly recommended.

1. Every postal code system uses only A-Z and/or 0-9 and sometimes space/dash

2. Not every country uses postal codes (ex. Ireland outside of Dublin), but we'll ignore that here.

3. The shortest postal code format is Sierra Leone with NN

4. The longest is American Samoa with NNNNN-NNNNNN

5. You should allow one space or dash.

6. Should not begin or end with space or dash

This should cover the above:

(?i)^[a-z0-9][a-z0-9\- ]{0,10}[a-z0-9]$

Best I can give you is a "works for me" on SVN 1.5. You may try adding --no-auth-cache to your svn update to see if that lets you override more easily.

If you want to permanently switch from user2 to user1, head into ~/.subversion/auth/ on *nix and delete the auth cache file for domain.com (most likely in ~/.subversion/auth/svn.simple/ -- just read through them and you'll find the one you want to drop). While it is possible to update the current auth cache, you have to make sure to update the length tokens as well. Simpler just to get prompted again next time you update.

You can achieve that by printing your string like:

<?php $string ='here is your string.'; print_r($string); ?>

Input: 0 0.1 1000

=FIXED(E5,2)

Output: 0.00 0.10 1,000.00

=TEXT(E5,"0.00")

Output: 0.00 0.10 1000.00

Note: As you can see FIXED add a coma after a thousand, where TEXT does not.

make sure the service is stopped, the services control panel is closed, and no open file handles are open by the service.

Also make sure ProcessExplorer is not running.

I use this:

import sqlite3

    db = sqlite3.connect('~/foo.sqlite')
    dbc = db.cursor()
    dbc.execute("PRAGMA table_info('bar')"
    ciao = dbc.fetchall()

    HeaderList=[]
    for i in ciao:
        counter=0
        for a in i:
            counter+=1
            if( counter==2):
                HeaderList.append(a)

print(HeaderList)

Determine whether the list of names is different with each query or reused. If it is reused, it belongs to the database.

Even if it is unique with each query, it may be useful to load it to a temporary table (#table syntax) for performance reasons - in that case you will be able to avoid recompilation of a complex query.

If the maximum number of names is fixed, you should use a parametrized query.

However, if none of the above cases applies, I would go with inlining the names in the query as in your approach #1.

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

UPDATE table SET columnB = columnA;

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

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

Your for loop looks good.

A possible while loop to accomplish the same thing:

int sum = 0;
int i = 1;
while (i <= 100) {
    sum += i;
    i++;
}
System.out.println("The sum is " + sum);

A possible do while loop to accomplish the same thing:

int sum = 0;
int i = 1;
do {
    sum += i;
    i++;
} while (i <= 100);
System.out.println("The sum is " + sum);

The difference between the while and the do while is that, with the do while, at least one iteration is sure to occur.

This cannot be done in pure java. But you can run external programs using java and get the result.

Process p=Runtime.getRuntime().exec("systeminfo");
Scanner scan=new Scanner(p.getInputStream());
while(scan.hasNext()){
    String temp=scan.nextLine();
    if(temp.equals("Available Physical Memmory")){
       System.out.println("RAM :"temp.split(":")[1]);
       break;
    }
}

I use a small set of documentation patterns:

• always documenting about thread-safety
• always documenting immutability
• javadoc with examples (like Formatter)
• @Deprecation with WHY and HOW to replace the annotated element

Using Bootstrap's built in .center-block class, which sets margin left and right to auto:

<iframe class="center-block" width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>

Or using the built in .text-center class, which sets text-align: center:

<div class="text-center">
  <iframe width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>

Generic way to update the any JSONObjet with new values.

private static void updateJsonValues(JsonObject jsonObj) {
    for (Map.Entry<String, JsonElement> entry : jsonObj.entrySet()) {
        JsonElement element = entry.getValue();
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {
            jsonObj.addProperty(entry.getKey(), "<provide new value>");
        }

    }
}

private static void parseJsonArray(JsonArray asJsonArray) {
    for (int index = 0; index < asJsonArray.size(); index++) {
        JsonElement element = asJsonArray.get(index);
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        }

    }
}

ShowPopUpForToDoList: function (id, apprId, tab) {
    var snapShot = "isFromAlert";
    if (tab != "Request")
        snapShot = "isFromTodoList";
    $.ajax({
        type: "GET",
        url: common.GetRootUrl('ActionForm/SetParamForToDoList'),
        data: { id: id, tab: tab },
        async:false,
        success: function (data) {
            ActionForm.EditActionFormPopup(id, snapShot);
        }
    });
},

Here SetParamForToDoList will be excecuted first after the function ActionForm.EditActionFormPopup will fire.

I've posted a script for generating all platform icons for PhoneGap apps from a single SVG icon file. If you have existing bitmaps, I also include some notes that may help you to generate the SVG vectors from an existing bitmap. This won't work for all bitmaps but may for yours.

It is not an anti-pattern to call setState in componentDidMount. In fact, ReactJS provides an example of this in their documentation:

You should populate data with AJAX calls in the componentDidMount lifecycle method. This is so you can use setState to update your component when the data is retrieved.

Example From Doc

componentDidMount() {
    fetch("https://api.example.com/items")
      .then(res => res.json())
      .then(
        (result) => {
          this.setState({
            isLoaded: true,
            items: result.items
          });
        },
        // Note: it's important to handle errors here
        // instead of a catch() block so that we don't swallow
        // exceptions from actual bugs in components.
        (error) => {
          this.setState({
            isLoaded: true,
            error
          });
        }
      )
  }

Move the session_start(); to top of the page always.

<?php
@ob_start();
session_start();
?>

You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:

FormBorderStyle    FixedToolWindow
ShowInTaskBar      False
StartPosition      CenterScreen

To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:

MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
    // etc
}

It would be advisable to add your own Show method that takes the text and other options you require:

public DialogResult Show(string text, Color foreColour)
{
     lblText.Text = text;
     lblText.ForeColor = foreColour;
     return this.ShowDialog();
}

You can try this:

Hope it works for you..

`private void validateUserEntry()
{
    // Checks the value of the text.
    if(serverName.Text.Length == 0)
    {
    // Initializes the variables to pass to the MessageBox.Show method.
    string message = "You did not enter a server name. Cancel this operation?";
    string caption = "Error Detected in Input";
    MessageBoxButtons buttons = MessageBoxButtons.YesNo;
    DialogResult result;

    // Displays the MessageBox.
    result = MessageBox.Show(message, caption, buttons);
    if (result == System.Windows.Forms.DialogResult.Yes)
    {
     // Closes the parent form.
        this.Close();
    }
    }
}` 

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

i had this problem when running the magento indexer in osx. and yes its related to php problem when connecting to mysql through pdo

in mac osx xampp, to fix this you have create symbolic link to directory /var/mysql, here is how

cd /var/mysql && sudo ln -s /Applications/XAMPP/xamppfiles/var/mysql/mysql.sock

if the directory /var/mysql doesnt exist, we must create it with

sudo mkdir /var/mysql

I wrote a module called Ng-Idle that may be useful to you in this situation. Here is the page which contains instructions and a demo.

Basically, it has a service that starts a timer for your idle duration that can be disrupted by user activity (events, such as clicking, scrolling, typing). You can also manually interrupt the timeout by calling a method on the service. If the timeout is not disrupted, then it counts down a warning where you could alert the user they are going to be logged out. If they do not respond after the warning countdown reaches 0, an event is broadcasted that your application can respond to. In your case, it could issue a request to kill their session and redirect to a login page.

Additionally, it has a keep-alive service that can ping some URL at an interval. This can be used by your app to keep a user's session alive while they are active. The idle service by default integrates with the keep-alive service, suspending the pinging if they become idle, and resuming it when they return.

All the info you need to get started is on the site with more details in the wiki. However, here's a snippet of config showing how to sign them out when they time out.

angular.module('demo', ['ngIdle'])
// omitted for brevity
.config(function(IdleProvider, KeepaliveProvider) {
  IdleProvider.idle(10*60); // 10 minutes idle
  IdleProvider.timeout(30); // after 30 seconds idle, time the user out
  KeepaliveProvider.interval(5*60); // 5 minute keep-alive ping
})
.run(function($rootScope) {
    $rootScope.$on('IdleTimeout', function() {
        // end their session and redirect to login
    });
});

Consider using SCSS. It's full compatible with CSS syntax, so a valid CSS file is also a valid SCSS file. This makes migration easy, just change the suffix. It has numerous enhancements, the most useful being variables and nested selectors.

You need to run it through a pre-processor to convert it to CSS before shipping it to the client.

I've been a hardcore CSS developer for many years now, but since forcing myself to do a project in SCSS, I now won't use anything else.

There's a slightly better way:

int valueParsed;
if(Int32.TryParse(txtMyText.Text.Trim(), out valueParsed))
{ ... }

If you try to parse the text and it can't be parsed, the Int32.Parse method will raise an exception. I think it is better for you to use the TryParse method which will capture the exception and let you know as a boolean if any exception was encountered.

There are lot of complications in parsing text which Int32.Parse takes into account. It is foolish to duplicate the effort. As such, this is very likely the approach taken by VB's IsNumeric. You can also customize the parsing rules through the NumberStyles enumeration to allow hex, decimal, currency, and a few other styles.

Another common approach for non-web based applications is to restrict the input of the text box to only accept characters which would be parseable into an integer.

EDIT: You can accept a larger variety of input formats, such as money values ("$100") and exponents ("1E4"), by specifying the specific NumberStyles:

int valueParsed;
if(Int32.TryParse(txtMyText.Text.Trim(), NumberStyles.AllowCurrencySymbol | NumberStyles.AllowExponent, CultureInfo.CurrentCulture, out valueParsed))
{ ... }

... or by allowing any kind of supported formatting:

int valueParsed;
if(Int32.TryParse(txtMyText.Text.Trim(), NumberStyles.Any, CultureInfo.CurrentCulture, out valueParsed))
{ ... }

If the forked repo is protected so you can't push directly into it, and your goal is to make changes to their foo, then you need to get their branch foo into your repo like so:

git remote add protected_repo https://github.com/theirusername/their_repo.git
git fetch protected_repo 
git checkout --no-track protected_repo/foo

Now you have a local copy of foo with no upstream associated to it. You can commit changes to it (or not) and then push your foo to your own remote repo.

git push --set-upstream origin foo

Now foo is in your repo on GitHub and your local foo is tracking it. If they continue to make changes to foo you can fetch theirs and merge into your foo.

git checkout foo 
git fetch protected_repo
git merge protected_repo/foo

A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.

If you want to control the width of your data, then you could use the width sub-specifiers in the printf format string. Eg. :

printf("%5d", 2);

It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.

If you want complete control, you'll probably have to implement it yourself.

Add position:fixed. Then the cover is fixed over the whole screen, also when you scroll.
And add maybe also margin: 0; padding:0; so it wont have some space's around the cover.

#dimScreen
{
    position:fixed;
    padding:0;
    margin:0;

    top:0;
    left:0;

    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5);
}

And if it shouldn't stick on the screen fixed, use position:absolute;

CSS Tricks have also an interesting article about fullscreen property.

Edit:
Just came across this answer, so I wanted to add some additional things.
Like Daniel Allen Langdon mentioned in the comment, add top:0; left:0; to be sure, the cover sticks on the very top and left of the screen.

If you some elements are at the top of the cover (so it doesn't cover everything), then add z-index. The higher the number, the more levels it covers.

You'll have problems creating lists without commas. It shouldn't be too hard to transform your data so that it uses commas as separating character.

Once you have commas in there, it's a relatively simple list creation operations:

array1 = [1,2,3]
array2 = [4,5,6]

array3 = [array1, array2]

array4 = [7,8,9]
array5 = [10,11,12]

array3 = [array3, [array4, array5]]

When testing we get:

print(array3)

[[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]

And if we test with indexing it works correctly reading the matrix as made up of 2 rows and 2 columns:

array3[0][1]
[4, 5, 6]

array3[1][1]
[10, 11, 12]

Hope that helps.

If you are switching on the value of a single variable then I'd use a switch every time, it's what the construct was made for.

Otherwise, stick with multiple if-else statements.

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

If you want to display single value access from database into textbox, please refer to the code below:

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
TextBox1.Text=cmd.ExecuteScalar();
Con.Close();

or

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
SqlDataReader dr=new SqlDataReadr();
dr=cmd.Executereader();
if(dr.read())
{
    TextBox1.Text=dr.GetValue(0).Tostring();
}
Con.Close();

To concatenate all the project manager names from projects that have multiple project managers write:

SELECT a.project_id,a.project_name,Stuff((SELECT N'/ ' + first_name + ', '+last_name FROM projects_v 
where a.project_id=project_id
 FOR
 XML PATH(''),TYPE).value('text()[1]','nvarchar(max)'),1,2,N''
) mgr_names
from projects_v a
group by a.project_id,a.project_name

there are two ways of doing it either you can use XML or Java for it. If it's static and requires no changes then you can initialize in XML.

  android:drawableLeft="@drawable/cloud_up"
    android:drawablePadding="5sp"

Now if you need to change the icons dynamically then you can do it by calling the icons based on the events

       textViewContext.setText("File Uploaded");
textViewContext.setCompoundDrawablesWithIntrinsicBounds(R.drawable.uploaded, 0, 0, 0);

You can do these conversions also with the .NET Framework:

JSON to XML: by using System.Runtime.Serialization.Json

var xml = XDocument.Load(JsonReaderWriterFactory.CreateJsonReader(
    Encoding.ASCII.GetBytes(jsonString), new XmlDictionaryReaderQuotas()));

XML to JSON: by using System.Web.Script.Serialization

var json = new JavaScriptSerializer().Serialize(GetXmlData(XElement.Parse(xmlString)));

private static Dictionary<string, object> GetXmlData(XElement xml)
{
    var attr = xml.Attributes().ToDictionary(d => d.Name.LocalName, d => (object)d.Value);
    if (xml.HasElements) attr.Add("_value", xml.Elements().Select(e => GetXmlData(e)));
    else if (!xml.IsEmpty) attr.Add("_value", xml.Value);

    return new Dictionary<string, object> { { xml.Name.LocalName, attr } };
}

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

I use

            chartRange = xlWorkSheet.Rows[1];
            chartRange.Font.Bold = true;

to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.

You can call in VBA directly

            ActiveCell.Font.Bold = True

With this code I create a timestamp in the active cell, with bold font and yellow background

           Private Sub Worksheet_SelectionChange(ByVal Target As Range)
               ActiveCell.Value = Now()
               ActiveCell.Font.Bold = True
               ActiveCell.Interior.ColorIndex = 6
           End Sub

// iterate over the map
for(Entry<String, ArrayList<String>> entry : test1.entrySet()){
    // iterate over each entry
    for(String item : entry.getValue()){
        // print the map's key with each value in the ArrayList
        System.out.println(entry.getKey() + ": " + item);
    }
}

If you are using Java 1.5 or later then this is an iterative binary GCD algorithm which uses Integer.numberOfTrailingZeros() to reduce the number of checks and iterations required.

public class Utils {
    public static final int gcd( int a, int b ){
        // Deal with the degenerate case where values are Integer.MIN_VALUE
        // since -Integer.MIN_VALUE = Integer.MAX_VALUE+1
        if ( a == Integer.MIN_VALUE )
        {
            if ( b == Integer.MIN_VALUE )
                throw new IllegalArgumentException( "gcd() is greater than Integer.MAX_VALUE" );
            return 1 << Integer.numberOfTrailingZeros( Math.abs(b) );
        }
        if ( b == Integer.MIN_VALUE )
            return 1 << Integer.numberOfTrailingZeros( Math.abs(a) );

        a = Math.abs(a);
        b = Math.abs(b);
        if ( a == 0 ) return b;
        if ( b == 0 ) return a;
        int factorsOfTwoInA = Integer.numberOfTrailingZeros(a),
            factorsOfTwoInB = Integer.numberOfTrailingZeros(b),
            commonFactorsOfTwo = Math.min(factorsOfTwoInA,factorsOfTwoInB);
        a >>= factorsOfTwoInA;
        b >>= factorsOfTwoInB;
        while(a != b){
            if ( a > b ) {
                a = (a - b);
                a >>= Integer.numberOfTrailingZeros( a );
            } else {
                b = (b - a);
                b >>= Integer.numberOfTrailingZeros( b );
            }
        }
        return a << commonFactorsOfTwo;
    }
}

Unit test:

import java.math.BigInteger;
import org.junit.Test;
import static org.junit.Assert.*;

public class UtilsTest {
    @Test
    public void gcdUpToOneThousand(){
        for ( int x = -1000; x <= 1000; ++x )
            for ( int y = -1000; y <= 1000; ++y )
            {
                int gcd = Utils.gcd(x, y);
                int expected = BigInteger.valueOf(x).gcd(BigInteger.valueOf(y)).intValue();
                assertEquals( expected, gcd );
            }
    }

    @Test
    public void gcdMinValue(){
        for ( int x = 0; x < Integer.SIZE-1; x++ ){
            int gcd = Utils.gcd(Integer.MIN_VALUE,1<<x);
            int expected = BigInteger.valueOf(Integer.MIN_VALUE).gcd(BigInteger.valueOf(1<<x)).intValue();
            assertEquals( expected, gcd );
        }
    }
}

There wasn't any luck here with the other answers, but I managed to work it out with this nice one-liner:

((GuidAttribute)(AppDomain.CurrentDomain.DomainManager.EntryAssembly).GetCustomAttributes(typeof(GuidAttribute), true)[0]).Value

In my opinion, it is a good practice to run Jupyter in a dedicated workbook folder.

$ mkdir jupyter_folder
$ jupyter-notebook --notebook-dir jupyter_folder

where 'jupyter_folder' is a folder in my home.

This method work without permission issue.

str.replace() ^v2|v3 does not recognize regular expressions.

To perform a substitution using a regular expression, use re.sub() ^v2|v3.

For example:

import re

line = re.sub(
           r"(?i)^.*interfaceOpDataFile.*$", 
           "interfaceOpDataFile %s" % fileIn, 
           line
       )

In a loop, it would be better to compile the regular expression first:

import re

regex = re.compile(r"^.*interfaceOpDataFile.*$", re.IGNORECASE)
for line in some_file:
    line = regex.sub("interfaceOpDataFile %s" % fileIn, line)
    # do something with the updated line

String path = "C:\\Documents and Settings\\someDir";

In Windows you should use four backslash but not two.

Had to debug a site for native Android browser and came here. So I tried weinre on an OS X 10.9 (as weinre server) with Firefox 30.0 (weinre client) and an Android 4.1.2 (target). I'm really, really surprised of the result.

1. Download and install node runtime from http://nodejs.org/download/
2. Install weinre: sudo npm -g install weinre
3. Find out your current IP address at Settings > Network
4. Setup a weinre server on your machine: weinre --boundHost YOUR.IP.ADDRESS.HERE
5. In your browser call: http://YOUR.IP.ADRESS.HERE:8080
6. You'll see a script snippet, place it into your site: <script src="http://YOUR.IP.ADDRESS.HERE:8080/target/target-script-min.js"></script>
7. Open the debug client in your local browser: http://YOUR.IP.ADDRESS.HERE:8080/client
8. Finally on your Android: call the site you want to inspect (the one with the script inside) and see how it appears as "Target" in your local browser. Now you can open "Elements" or whatever you want.

Maybe 8080 isn't your default port. Then in step 4 you have to call weinre --httpPort YOURPORT --boundHost YOUR.IP.ADRESS.HERE.

And I don't remember exactly when it was, maybe somewhere after step 5, I had to accept incoming connections prompt, of course.

Happy debugging

P.S. I'm still overwhelmed how good that works. Even elements-highlighting work

Make the method type [HttpPost], create a model that has one int[] parameter, and post with json:

/* Model */
public class CategoryRequestModel 
{
    public int[] Categories { get; set; }
}

/* WebApi */
[HttpPost]
public HttpResponseMessage GetCategories(CategoryRequestModel model)
{
    HttpResponseMessage resp = null;

    try
    {
        var categories = //your code to get categories

        resp = Request.CreateResponse(HttpStatusCode.OK, categories);

    }
    catch(Exception ex)
    {
        resp = Request.CreateErrorResponse(HttpStatusCode.InternalServerError, ex);
    }

    return resp;
}

/* jQuery */
var ajaxSettings = {
    type: 'POST',
    url: '/Categories',
    data: JSON.serialize({Categories: [1,2,3,4]}),
    contentType: 'application/json',
    success: function(data, textStatus, jqXHR)
    {
        //get categories from data
    }
};

$.ajax(ajaxSettings);

You can react to new file activity with FileSystemWatcher.

For me it's Enterprise Architect from Sparx Systems. A very rounded UML tool for a very reasonable price.

Very strong feature list including: integrated project management, baselining, export/import (including export to html), documentation generation from the model, various templates (Zachman, TOGAF, etc.), IDE plugins, code generation (with IDE plugins available for Visual Studio, Eclipse & others), automation API - the list goes on.

Oh yeah, don't forget support for source control directly from inside the tool (SVN, CVS, TFS & SCC).

I would also stay away from Visio - you only get diagrams, not a model. Rename a class in one place in a UML modelling tool and you rename in all places. This is not the case in Visio!

Open eclipse.ini in the installation directory, and observe the line with text:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 then it is 64 bit.

If it would be plugins/org.eclipse.equinox.launcher.win32.win32.x86_32_1.0.200.v20090519 then it is 32 bit.

How to generate SQL scripts for your database in Workbench

1. In Workbench Central (the default "Home" tab) connect to your MySQL instance, opening a SQL Editor tab.
2. Click on the SQL Editor tab and select your database from the SCHEMAS list in the Object Browser on the left.
3. From the menu select Database > Reverse Engineer and follow the prompts. The wizard will lead you through connecting to your instance, selecting your database, and choosing the types of objects you want to reverse engineer. When you're all done, you will have at least one new tab called MySQL Model. You may also have a tab called EER Diagram which is cool but not relevant here.
4. Click in the MySQL Model tab
5. Select Database > Forward Engineer
6. Follow the prompts. Many options present themselves, including Generate INSERT Scripts for Tables which allows you to script out the data contained within your tables (perfect for lookup tables).
7. Soon you will see the generated script in front of you. At this point you can Copy to Clipboard or Save to Text File.

The wizard will take you further, but if you just want the script you can stop here.

A word of caution: the scripts are generated with CREATE commands. If you want ALTER you'll have to (as far as I can tell) manually change the CREATEs to ALTERs.

This is guaranteed to work, I just did it tonight.

Another issue is that your database may be in a "non-trusted" location. Go to the trust center settings and add your database location to the trusted locations list.

Use the -S option:

gcc -S program.c

Today i was facing same problem. I was in very difficult situation but what id did i create a table with diffrent name e.g (modulemaster was not creating then i create modulemaster1) and after creating table i just do the rename table.

replace:

input, select, textarea{
    color: #000;
}

with:

input, select, textarea{
    color: #f00;
}

or color: #ff0000;

Here is one possible case:

map(lambda op1,op2: op1*op2, list1, list2)

versus:

[op1*op2 for op1,op2 in zip(list1,list2)]

I am guessing the zip() is an unfortunate and unnecessary overhead you need to indulge in if you insist on using list comprehensions instead of the map. Would be great if someone clarifies this whether affirmatively or negatively.

$query    =    "SELECT username, userid FROM user WHERE username = 'admin' ";
$result    =    $conn->query($query);

if (!$result) {
  echo 'Could not run query: ' . mysql_error();
  exit;
}

$arrayResult    =    mysql_fetch_array($result);

//Now you can access $arrayResult like this

$arrayResult['userid'];    // output will be userid which will be in database
$arrayResult['username'];  // output will be admin

//Note- userid and username will be column name of user table.

Ruby on rails uses :: for namespace resolution.

class User < ActiveRecord::Base

  VIDEOS_COUNT = 10
  Languages = { "English" => "en", "Spanish" => "es", "Mandarin Chinese" => "cn"}

end

To use it :

User::VIDEOS_COUNT
User::Languages
User::Languages.values_at("Spanish") => "en"

Also, other usage is : When using nested routes

OmniauthCallbacksController is defined under users.

And routed as:

devise_for :users, controllers: {omniauth_callbacks: "users/omniauth_callbacks"}


class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController

end

You could add an event handler to your input like so:

document.getElementById('addLinks').onkeypress=function(e){
    if(e.keyCode==13){
        document.getElementById('linkadd').click();
    }
}

You simply use Explicit conversion Cast int to enum or enum to int

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine((int)Number.three); //Output=3

        Console.WriteLine((Number)3);// Outout three
        Console.Read();
    }

    public enum Number
    {
        Zero = 0,
        One = 1,
        Two = 2,
        three = 3
    }
}

You edit an element's value by editing it's .value property.

document.getElementById('DATE').value = 'New Value';

I know this is an old thread but what solved the issue for me was adding the following to my build.gradle files. As already stated above there is a compatibility issue with mockito-all

Possibly useful post:

testCompile ('junit:junit:4.12') {
    exclude group: 'org.hamcrest'
}
testCompile ('org.mockito:mockito-core:1.10.19') {
    exclude group: 'org.hamcrest'
}
testCompile 'org.hamcrest:hamcrest-core:1.3'

Compatibility Guide for JDK 8 says that in Java 8 the command line flag MaxPermSize has been removed. The reason is that the permanent generation was removed from the hotspot heap and was moved to native memory. So in order to remove this message edit MAVEN_OPTS Environment User Variable:

Java 7

MAVEN_OPTS -Xmx512m -XX:MaxPermSize=128m

Java 8

MAVEN_OPTS -Xmx512m

This loops vertically but might work for you.

int rtn = 0;    
foreach(int[] L in lists){
    for(int i = 0; i<L.Length;i++){
          rtn = L[i];
      //Do something with rtn
    }
}

Here's a handy variation that I don't see mentioned in the faq. You can return the current message for editing by specifying a text editor.

svn propedit svn:log --revprop -r N --editor-cmd vim

try running the following command:

pip install mysqlclient

max-age=0, must-revalidate and no-cache aren't exactly identical. With must-revalidate, if the server doesn't respond to a revalidation request, the browser/proxy is supposed to return a 504 error. With no-cache, it would just show the cached content, which would be probably preferred by the user (better to have something stale than nothing at all). This is why must-revalidate is intended for critical transactions only.

I just got the same problem and to fix it, I opened the task manager and killed the adb.exe process, then I restarted Eclipse.

In Simpler words, Pig is a high-level platform for creating MapReduce programs used with Hadoop, using pig scripts we will process the large amount of data into desired format.

Once the processed data obtained, this processed data is kept in HDFS for later processing to obtain the desired results.

On top of the stored processed data we will apply HIVE SQL commands to get the desired results, internally this hive sql commands runs MAP Reduce programs.

break ends the loop that it is currently in. So, you are only ever checking if it divisible by 2, giving you all odd numbers.

for num in range(2,101):
    for i in range(2,num):
        if (num%i==0):
            break
    else:
        print(num)

that being said, there are much better ways to find primes in python than this.

for num in range(2,101):
    if is_prime(num):
        print(num)

def is_prime(n):
    for i in range(2, int(math.sqrt(n)) + 1):
        if n % i == 0:
            return False
    return True

kindly executed these commands.

pip install google
pip install google-core-api

will definitely solve your problem

Before pushing, do a git pull with rebase option. This will get the changes that you made online (in your origin) and apply them locally, then add your local changes on top of it.

git pull --rebase

Now, you can push to remote

git push 

For more information take a look at Git rebase explained and Chapter 3.6 Git Branching - Rebasing.

UPDATE  table
SET     columnx = CASE WHEN condition THEN 25 ELSE columnx END,
        columny = CASE WHEN condition THEN columny ELSE 25 END

I found this article and tried the tutorial. Basically, you can use the date constructor to parse a date, then write get the seconds from the getTime() method

var d=new Date("October 13, 1975 11:13:00");
document.write(d.getTime() + " milliseconds since 1970/01/01");

Does this work?

Use event delegation by assigning the onclick to the <ol>. Then pass the event object as the argument, and using that, grab the text from the clicked element.

function addText(event) {_x000D_
    var targ = event.target || event.srcElement;_x000D_
    document.getElementById("alltext").value += targ.textContent || targ.innerText;_x000D_
}

<textarea id="alltext"></textarea>_x000D_
_x000D_
<ol onclick="addText(event)">_x000D_
  <li>Hello</li>_x000D_
  <li>World</li>_x000D_
  <li>Earthlings</li>_x000D_
</ol>

Note that this method of passing the event object works in older IE as well as W3 compliant systems.

As a rule of thumb, I would generally use === instead of == (and !== instead of !=).

Reasons are explained in in the answers above and also Douglas Crockford is pretty clear about it (JavaScript: The Good Parts).

However there is one single exception: == null is an efficient way to check for 'is null or undefined':

if( value == null ){
    // value is either null or undefined
}

For example jQuery 1.9.1 uses this pattern 43 times, and the JSHint syntax checker even provides the eqnull relaxing option for this reason.

From the jQuery style guide:

Strict equality checks (===) should be used in favor of ==. The only exception is when checking for undefined and null by way of null.

// Check for both undefined and null values, for some important reason. 
undefOrNull == null;

The same problem arrised for me when I installed Kaliko CMS Nuget Package. When I removed it, it started working fine again. So, your problem could be because of a recently installed Nuget Package. Uninstall it and your solution will work just fine.

make input to block and float, Adjust margin top value.

HTML:

height:18px;
width:18px;
padding:0;
margin-top:5px;
display:block;

For current datetime, you can use now() function in postgresql insert query.

You can also refer following link.

As others have said this can be caused when you've not installed an app that is listed in INSTALLED_APPS.

In my case, manage.py was attempting to log the exception, which led to an attempt to render it which failed due to the app not being initialized yet. By commenting out the except clause in manage.py the exception was displayed without special rendering, avoiding the confusing error.

# Temporarily commenting out the log statement.
#try:
    execute_from_command_line(sys.argv)
#except Exception as e:
#    log.error('Admin Command Error: %s', ' '.join(sys.argv), exc_info=sys.exc_info())
#    raise e

You need to define the enum outside of the class.

public enum card_suits
{
    Clubs,
    Hearts,
    Spades,
    Diamonds
}

public class Card
{
     // ...

That being said, you may also want to consider using the standard naming guidelines for Enums, which would be CardSuit instead of card_suits, since Pascal Casing is suggested, and the enum is not marked with the FlagsAttribute, suggesting multiple values are appropriate in a single variable.

egit has a serious bug when comparing a file in your working dir with an earlier - it flashes a blank tab. The bug has been around since 2010 and still has not been fixed. This very basic feature which works very well in svn plugin is completely broken.

They're already ints. Why not just use subtraction?

compare = a - b;

Note that Integer.compareTo() doesn't necessarily return only -1, 0 or 1 either.
