Programs & Examples On #Assertraises

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

The usual way to use assertRaises is to call a function:

self.assertRaises(TypeError, test_function, args)

to test that the function call test_function(args) raises a TypeError.

The problem with self.testListNone[:1] is that Python evaluates the expression immediately, before the assertRaises method is called. The whole reason why test_function and args is passed as separate arguments to self.assertRaises is to allow assertRaises to call test_function(args) from within a try...except block, allowing assertRaises to catch the exception.

Since you've defined self.testListNone = None, and you need a function to call, you might use operator.itemgetter like this:

import operator
self.assertRaises(TypeError, operator.itemgetter, (self.testListNone,slice(None,1)))

since

operator.itemgetter(self.testListNone,slice(None,1))

is a long-winded way of saying self.testListNone[:1], but which separates the function (operator.itemgetter) from the arguments.

def _assertNotRaises(self, exception, obj, attr):                                                                                                                              
     try:                                                                                                                                                                       
         result = getattr(obj, attr)                                                                                                                                            
         if hasattr(result, '__call__'):                                                                                                                                        
             result()                                                                                                                                                           
     except Exception as e:                                                                                                                                                     
         if isinstance(e, exception):                                                                                                                                           
            raise AssertionError('{}.{} raises {}.'.format(obj, attr, exception)) 

could be modified if you need to accept parameters.

call like

self._assertNotRaises(IndexError, array, 'sort')

You shouldn't raise the warning, you should be using warnings module. By raising it you're generating error, rather than warning.

Simple and Easiest code you can use it to share image from gallery.

 String image_path;
            File file = new File(image_path);
            Uri uri = Uri.fromFile(file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent .setType("image/*");
            intent .putExtra(Intent.EXTRA_STREAM, uri);
            context.startActivity(intent );

Additionally you will probably want to redirect user to the given in headers URL. So finally it will looks like this:

$.ajax({
    //.... other definition
    complete:function(xmlHttp){
        if(xmlHttp.status.toString()[0]=='3'){
        top.location.href = xmlHttp.getResponseHeader('Location');
    }
});

UPD: Opps. Have the same task, but it not works. Doing this stuff. I'll show you solution when I'll find it.

I know this is an old topic. I had the same problem. I tested all the answers about this topic. And nothing worked here... but i found another solution.

Go to pom->overview and add these to you properties:

• Name: "maven.compiler.target" Value: "1.7"

and

• Name: "maven.compiler.source" Value: "1.7"

Now do a maven update.

I use Eclipse Java EE edition

Create a "Dynamic Web Project"

Install a local server in the server view, for the version of Tomcat I'm using. Then debug, and run on that server for testing.

When I deploy I export the project to a war file.

I have used Tinybox 2 for small projects : http://sandbox.scriptiny.com/tinybox2/

np.where returns a tuple of length equal to the dimension of the numpy ndarray on which it is called (in other words ndim) and each item of tuple is a numpy ndarray of indices of all those values in the initial ndarray for which the condition is True. (Please don't confuse dimension with shape)

For example:

x=np.arange(9).reshape(3,3)
print(x)
array([[0, 1, 2],
      [3, 4, 5],
      [6, 7, 8]])
y = np.where(x>4)
print(y)
array([1, 2, 2, 2], dtype=int64), array([2, 0, 1, 2], dtype=int64))

y is a tuple of length 2 because x.ndim is 2. The 1st item in tuple contains row numbers of all elements greater than 4 and the 2nd item contains column numbers of all items greater than 4. As you can see, [1,2,2,2] corresponds to row numbers of 5,6,7,8 and [2,0,1,2] corresponds to column numbers of 5,6,7,8 Note that the ndarray is traversed along first dimension(row-wise).

Similarly,

x=np.arange(27).reshape(3,3,3)
np.where(x>4)

will return a tuple of length 3 because x has 3 dimensions.

But wait, there's more to np.where!

when two additional arguments are added to np.where; it will do a replace operation for all those pairwise row-column combinations which are obtained by the above tuple.

x=np.arange(9).reshape(3,3)
y = np.where(x>4, 1, 0)
print(y)
array([[0, 0, 0],
   [0, 0, 1],
   [1, 1, 1]])

A variation of DixonD's excellent answer (above).

public static bool TryOpen(string path,
                           FileMode fileMode,
                           FileAccess fileAccess,

    }

    stream = null;
    return false;
}

private static bool FileIsLocked(IOException ioException)
{
    var errorCode = (uint)Marshal.GetHRForException(ioException);
    return errorCode == HRFileLocked || errorCode == HRPortionOfFileLocked;

Usage:

private void Sample(string filePath)
{
    Stream stream = null;

    try
    {
        var timeOut = TimeSpan.FromSeconds(1);

        if (!TryOpen(filePath,
                     FileMode.Open,
                     FileAccess.ReadWrite,
                     FileShare.ReadWrite,
                     timeOut,
                     out stream))
            return;

        // Use stream...
    }
    finally
    {
        if (stream != null)
            stream.Close();
    }
}

You can use a kind of continue by using a nested Do ... Loop While False:

'This sample will output 1 and 3 only

Dim i As Integer

For i = 1 To 3: Do

    If i = 2 Then Exit Do 'Exit Do is the Continue

    Debug.Print i

Loop While False: Next i

An object is defined by an OBJECT_ID, which is unique. If A and B are objects and A == B is true, then they are the very same object, they have the same data and methods, but, this is also true:

A.OBJECT_ID == B.OBJECT_ID

if A.Equals(B) is true, that means that the two objects are in the same state, but this doesn't mean that A is the very same as B.

Strings are objects.

Note that the == and Equals operators are reflexive, simetric, tranzitive, so they are equivalentic relations (to use relational algebraic terms)

What this means: If A, B and C are objects, then:

(1) A == A is always true; A.Equals(A) is always true (reflexivity)

(2) if A == B then B == A; If A.Equals(B) then B.Equals(A) (simetry)

(3) if A == B and B == C, then A == C; if A.Equals(B) and B.Equals(C) then A.Equals(C) (tranzitivity)

Also, you can note that this is also true:

(A == B) => (A.Equals(B)), but the inverse is not true.

A B =>
0 0 1
0 1 1
1 0 0
1 1 1

Example of real life: Two Hamburgers of the same type have the same properties: they are objects of the Hamburger class, their properties are exactly the same, but they are different entities. If you buy these two Hamburgers and eat one, the other one won't be eaten. So, the difference between Equals and ==: You have hamburger1 and hamburger2. They are exactly in the same state (the same weight, the same temperature, the same taste), so hamburger1.Equals(hamburger2) is true. But hamburger1 == hamburger2 is false, because if the state of hamburger1 changes, the state of hamburger2 not necessarily change and vice versa.

If you and a friend get a Hamburger, which is yours and his in the same time, then you must decide to split the Hamburger into two parts, because you.getHamburger() == friend.getHamburger() is true and if this happens: friend.eatHamburger(), then your Hamburger will be eaten too.

I could write other nuances about Equals and ==, but I'm getting hungry, so I have to go.

In my case i was using a generic fragment holder using in my activity class and i was replacing this generic fragment with proper fragments at runtime.

Problem was i was giving id's to both include and generic_fragment_layout , removing id from include solved it.

In C++11 and C++14 we have much better options with the random header. The presentation rand() Considered Harmful by Stephan T. Lavavej explains why we should eschew the use of rand() in C++ in favor of the random header and N3924: Discouraging rand() in C++14 further reinforces this point.

The example below is a modified version of the sample code on the cppreference site and uses the std::mersenne_twister_engine engine and the std::uniform_real_distribution which generates numbers in the [0,1) range (see it live):

#include <iostream>
#include <iomanip>
#include <map>
#include <random>

int main()
{
    std::random_device rd;


    std::mt19937 e2(rd());

    std::uniform_real_distribution<> dist(0, 1);

    std::map<int, int> hist;
    for (int n = 0; n < 10000; ++n) {
        ++hist[std::round(dist(e2))];
    }

    for (auto p : hist) {
        std::cout << std::fixed << std::setprecision(1) << std::setw(2)
                  << p.first << ' ' << std::string(p.second/200, '*') << '\n';
    }
}

output will be similar to the following:

0 ************************
1 *************************

Since the post mentioned that speed was important then we should consider the cppreference section that describes the different random number engines (emphasis mine):

The choice of which engine to use involves a number of tradeoffs*: the **linear congruential engine is moderately fast and has a very small storage requirement for state. The lagged Fibonacci generators are very fast even on processors without advanced arithmetic instruction sets, at the expense of greater state storage and sometimes less desirable spectral characteristics. The Mersenne twister is slower and has greater state storage requirements but with the right parameters has the longest non-repeating sequence with the most desirable spectral characteristics (for a given definition of desirable).

So if there is a desire for a faster generator perhaps ranlux24_base or ranlux48_base are better choices over mt19937.

rand()

If you forced to use rand() then the C FAQ for a guide on How can I generate floating-point random numbers?, gives us an example similar to this for generating an on the interval [0,1):

#include <stdlib.h>

double randZeroToOne()
{
    return rand() / (RAND_MAX + 1.);
}

and to generate a random number in the range from [M,N):

double randMToN(double M, double N)
{
    return M + (rand() / ( RAND_MAX / (N-M) ) ) ;  
}

According to the documentation:

$validator = Validator::make($request->all(), [
    'file' => 'max:500000',
]);

The value is in kilobytes. I.e. max:10240 = max 10 MB.

openFileInput() doesn't accept paths, only a file name if you want to access a path, use File file = new File(path) and corresponding FileInputStream

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

Django 1.10 no longer allows you to specify views as a string (e.g. 'myapp.views.home') in your URL patterns.

The solution is to update your urls.py to include the view callable. This means that you have to import the view in your urls.py. If your URL patterns don't have names, then now is a good time to add one, because reversing with the dotted python path no longer works.

from django.conf.urls import include, url

from django.contrib.auth.views import login
from myapp.views import home, contact

urlpatterns = [
    url(r'^$', home, name='home'),
    url(r'^contact/$', contact, name='contact'),
    url(r'^login/$', login, name='login'),
]

If there are many views, then importing them individually can be inconvenient. An alternative is to import the views module from your app.

from django.conf.urls import include, url

from django.contrib.auth import views as auth_views
from myapp import views as myapp_views

urlpatterns = [
    url(r'^$', myapp_views.home, name='home'),
    url(r'^contact/$', myapp_views.contact, name='contact'),
    url(r'^login/$', auth_views.login, name='login'),
]

Note that we have used as myapp_views and as auth_views, which allows us to import the views.py from multiple apps without them clashing.

See the Django URL dispatcher docs for more information about urlpatterns.

There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.

Though PuTTY supports connection-sharing.

While you still need to run a compatible file transfer client (pscp or psftp), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.

To enable the sharing see:
Sharing an SSH connection between PuTTY tools.

Even without connection-sharing, you can still use the psftp or pscp from Windows command line.

See How to use PSCP to copy file from Unix machine to Windows machine ...?

Note that the scp is OpenSSH program. It's primarily *nix program, but you can run it via Windows Subsystem for Linux or get a Windows build from Win32-OpenSSH (it is already built-in in the latest versions of Windows 10).

If you really want to download the files to a local desktop, you have to specify a target path as %USERPROFILE%\Desktop (what typically resolves to a path like C:\Users\username\Desktop).

Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY command.
See Opening Session in PuTTY.

With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the same directory.

(I'm the author of WinSCP)

This is my solution to deep remove empty properties with Lodash:

const compactDeep = obj => {
    const emptyFields = [];

    function calculateEmpty(prefix, source) {
        _.each(source, (val, key) => {
           if (_.isObject(val) && !_.isEmpty(val)) {
                calculateEmpty(`${prefix}${key}.`, val);
            } else if ((!_.isBoolean(val) && !_.isNumber(val) && !val) || (_.isObject(val) && _.isEmpty(val))) {
                emptyFields.push(`${prefix}${key}`);
            }
        });
    }

    calculateEmpty('', obj);

    return _.omit(obj, emptyFields);
};

Could use sprintf to accomplish this:

awk '{str = sprintf("%s %s", $1, $2)} END {print str}' file

They're simply different schemes for representing Unicode characters.

Both are variable-length - UTF-16 uses 2 bytes for all characters in the basic multilingual plane (BMP) which contains most characters in common use.

UTF-8 uses between 1 and 3 bytes for characters in the BMP, up to 4 for characters in the current Unicode range of U+0000 to U+1FFFFF, and is extensible up to U+7FFFFFFF if that ever becomes necessary... but notably all ASCII characters are represented in a single byte each.

For the purposes of a message digest it won't matter which of these you pick, so long as everyone who tries to recreate the digest uses the same option.

See this page for more about UTF-8 and Unicode.

(Note that all Java characters are UTF-16 code points within the BMP; to represent characters above U+FFFF you need to use surrogate pairs in Java.)

Normally there are two ways of initializing variables, 1) using the sess.run(tf.global_variables_initializer()) as the previous answers noted; 2) the load the graph from checkpoint.

You can do like this:

sess = tf.Session(config=config)
saver = tf.train.Saver(max_to_keep=3)
try:
    saver.restore(sess, tf.train.latest_checkpoint(FLAGS.model_dir))
    # start from the latest checkpoint, the sess will be initialized 
    # by the variables in the latest checkpoint
except ValueError:
    # train from scratch
    init = tf.global_variables_initializer()
    sess.run(init)

And the third method is to use the tf.train.Supervisor. The session will be

Create a session on 'master', recovering or initializing the model as needed, or wait for a session to be ready.

sv = tf.train.Supervisor([parameters])
sess = sv.prepare_or_wait_for_session()

you can wrap -Andrie answer into a generic function

mbind<-function(...){
 Reduce( function(x,y){cbind(x,y[match(row.names(x),row.names(y)),])}, list(...) )
}

Here, you can bind multiple frames with rownames as key

If you give a Scanner object a String, it will read it in as data. That is, "a.txt" does not open up a file called "a.txt". It literally reads in the characters 'a', '.', 't' and so forth.

This is according to Core Java Volume I, section 3.7.3.

If I find a solution to reading the actual paths, I will return and update this answer. The solution this text offers is to use

Scanner in = new Scanner(Paths.get("myfile.txt"));

But I can't get this to work because Path isn't recognized as a variable by the compiler. Perhaps I'm missing an import statement.

If you're brave and willing to roll your own, you could start with a PostScript library and augment it to deal with PDF, taking advantage of Adobe's free online PDF reference.

From the output of "ps aux | grep docker", it looks like docker daemon is not running. Try using below methods to see what is wrong and why docker is not starting

1. Check the docker logs

$ sudo tail -f /var/log/upstart/docker.log

2. Try starting docker in debug mode

ActivityLifecycleCallbacks might be of interest, but it isn't well documented.

Though, if you call registerActivityLifecycleCallbacks() you should be able to get callbacks for when Activities are created, destroyed, etc. You can call getComponentName() for the Activity.

Hi For jQuery You can only use like this

Use async and type="text/javascript" only

As an addition to the solution:

ul li:before {
 content: '?'; 
}

You can use any SVG icon as the content, such as the Font Aswesome.

ul {_x000D_
  list-style: none;_x000D_
  padding-left: 0;_x000D_
}_x000D_
li {_x000D_
  position: relative;_x000D_
  padding-left: 1.5em;  /* space to preserve indentation on wrap */_x000D_
}_x000D_
li:before {_x000D_
  content: '';  /* placeholder for the SVG */_x000D_
  position: absolute;_x000D_
  left: 0;  /* place the SVG at the start of the padding */_x000D_
  width: 1em;_x000D_
  height: 1em;_x000D_
  background: url("data:image/svg+xml;utf8,<?xml version='1.0' encoding='utf-8'?><svg width='18' height='18' viewBox='0 0 1792 1792' xmlns='http://www.w3.org/2000/svg'><path d='M1671 566q0 40-28 68l-724 724-136 136q-28 28-68 28t-68-28l-136-136-362-362q-28-28-28-68t28-68l136-136q28-28 68-28t68 28l294 295 656-657q28-28 68-28t68 28l136 136q28 28 28 68z'/></svg>") no-repeat;_x000D_
}

<ul>_x000D_
  <li>this is my text</li>_x000D_
  <li>this is my text</li>_x000D_
  <li>This is my text, it's pretty long so it needs to wrap. Note that wrapping preserves the indentation that bullets had!</li>_x000D_
  <li>this is my text</li>_x000D_
  <li>this is my text</li>_x000D_
</ul>

Note: To solve the wrapping problem that other answers had:

• we reserve 1.5m ems of space at the left of each <li>
• then position the SVG at the start of that space (position: absolute; left: 0)

I came across this issue twice once in upgrading to 3.2.18 from 3.2.1 and 4.3.5 from 3.2.8. In both cases, this error is because of different version of spring modules

I would rather prefer that you use BitBucket, as it is not public and there is an official tutorial by Unity on Bitbucket.

hope this helps.

Is the div a fixed width or a fluid width? Either way, for fluid width you could use:

#element { /* this is the child div */
margin-left:auto;
margin-right:auto;
/* Add remaining styling here */
}

Or you could set the parent div to text-align:center; and the child div to text-align:left;.

And left:50%; only centers it according to the whole page when the div is set to position:absolute;. If yous set the div to left:50%; it should do it relative to the parent div's width. For fixed width, do this:

#parent {
width:500px;
}

#child {
left:50%;
margin-left:-100px;
width:200px;
}

There's already a lot of good answers here so why not one more, use a library like lodash or underscore :)

obj = {
   1 : { name : 'bob' , dinner : 'pizza' },
   2 : { name : 'john' , dinner : 'sushi' },
   3 : { name : 'larry', dinner : 'hummus' }
}

_.where(obj, {dinner: 'pizza'})
>> [{"name":"bob","dinner":"pizza"}]

Hope not to be late. It is accomplished using only one line!

-webkit-transition: all 0.2s ease-in-out, width 0, height 0, top 0, left 0;
-moz-transition: all 0.2s ease-in-out, width 0, height 0, top 0, left 0;
-o-transition: all 0.2s ease-in-out, width 0, height 0, top 0, left 0;
transition: all 0.2s ease-in-out, width 0, height 0, top 0, left 0; 

That works on Chrome. You have to separate the CSS properties with a comma.

Here is a working example: http://jsfiddle.net/H2jet/

If you want to use special character in javascript variable value, Escape Character (\) is required.

Backslash in your example is special character, too.

So you should do something like this,

var ttt = "aa ///\\\\\\"; // --> ///\\\

or

var ttt = "aa ///\\"; // --> ///\

But Escape Character not require for user input.

When you press / in prompt box or input field then submit, that means single /.

You cannot instantiate an interface - you must provide a concrete implementation of IEnumerable.

Here's an approach which uses a gradient to fake the line. It works with multiline strikes and doesn't need additional DOM elements. But as it's a background gradient, it's behind the text...

del, strike {
  text-decoration: none;
  line-height: 1.4;
  background-image: -webkit-gradient(linear, left top, left bottom, from(transparent), color-stop(0.63em, transparent), color-stop(0.63em, #ff0000), color-stop(0.7em, #ff0000), color-stop(0.7em, transparent), to(transparent));
  background-image: -webkit-linear-gradient(top, transparent 0em, transparent 0.63em, #ff0000 0.63em, #ff0000 0.7em, transparent 0.7em, transparent 1.4em);
  background-image: -o-linear-gradient(top, transparent 0em, transparent 0.63em, #ff0000 0.63em, #ff0000 0.7em, transparent 0.7em, transparent 1.4em);
  background-image: linear-gradient(to bottom, transparent 0em, transparent 0.63em, #ff0000 0.63em, #ff0000 0.7em, transparent 0.7em, transparent 1.4em);
  -webkit-background-size: 1.4em 1.4em;
  background-size: 1.4em 1.4em;
  background-repeat: repeat;
}

See fiddle: http://jsfiddle.net/YSvaY/

Gradient color-stops and background size depend on line-height. (I used LESS for calculation and Autoprefixer afterwards...)

step-1

open -> Visual Studio 2017 Developer Command Prompt

step-2

WSDL.exe  /OUT:myFile.cs WSDLURL  /Language:CS /serverInterface

• /serverInterface (this to create interface from wsdl file)
• WSDL.exe (this use to create class from wsdl. this comes with .net
• /OUT: (output file name)

step-2

create new "Web service Project"

step-3

add -> web service

step-4

copy all code from myFile.cs (generated above) except "using classes" eg:

 /// <remarks/>
    [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "4.6.1055.0")]
    [System.Web.Services.WebServiceBindingAttribute(Name="calculoterServiceSoap",Namespace="http://tempuri.org/")]

    string addition(int firtNo, int secNo);
}

step-4

past it into your webService.asmx.cs (inside of namespace) created above in step-2

step-5

inherit the interface class with your web service class eg:

public class WebService2 : ICalculoterServiceSoap

As other posters have mentioned, I'd suggest you have a look at aria2. From the Ubuntu man page for version 1.16.1:

aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. aria2 can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.

You can use the -x flag to specify the maximum number of connections per server (default: 1):

aria2c -x 16 [url] 

If the same file is available from multiple locations, you can choose to download from all of them. Use the -j flag to specify the maximum number of parallel downloads for every static URI (default: 5).

aria2c -j 5 [url] [url2]

Have a look at http://aria2.sourceforge.net/ for more information. For usage information, the man page is really descriptive and has a section on the bottom with usage examples. An online version can be found at http://aria2.sourceforge.net/manual/en/html/README.html.

I faced this issue, I was not able to copy zeppelin [1GB] directory into docker container and was getting issue

COPY failed: stat /var/lib/docker/tmp/docker-builder977188321/zeppelin-0.7.2-bin-all: no such file or directory

I am using docker Version: 17.09.0-ce and resolved the issue with the following steps.

Step 1: copy zeppelin directory [which i want to copy into docker package]into directory contain "Dockfile"

Step 2: edit Dockfile and add command [location where we want to copy] ADD ./zeppelin-0.7.2-bin-all /usr/local/

Step 3: go to directory which contain DockFile and run command [alternatives also available] docker build

Step 4: docker image created Successfully with logs

OK, finally we have an answer...

You are correctly specifying headers: {"Content-Type": "application/json"}, to set your content type. Under the hood either the package http or the lower level dart:io HttpClient is changing this to application/json; charset=utf-8. However, your server web application obviously isn't expecting the suffix.

To prove this I tried it in Java, with the two versions

conn.setRequestProperty("content-type", "application/json; charset=utf-8"); // fails
conn.setRequestProperty("content-type", "application/json"); // works

Are you able to contact the web application owner to explain their bug? I can't see where Dart is adding the suffix, but I'll look later.

EDIT Later investigation shows that it's the http package that, while doing a lot of the grunt work for you, is adding the suffix that your server dislikes. If you can't get them to fix the server then you can by-pass http and use the dart:io HttpClient directly. You end up with a bit of boilerplate which is normally handled for you by http.

Working example below:

import 'dart:convert';
import 'dart:io';
import 'dart:async';

main() async {
  String url =
      'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
  Map map = {
    'data': {'apikey': '12345678901234567890'},
  };

  print(await apiRequest(url, map));
}

Future<String> apiRequest(String url, Map jsonMap) async {
  HttpClient httpClient = new HttpClient();
  HttpClientRequest request = await httpClient.postUrl(Uri.parse(url));
  request.headers.set('content-type', 'application/json');
  request.add(utf8.encode(json.encode(jsonMap)));
  HttpClientResponse response = await request.close();
  // todo - you should check the response.statusCode
  String reply = await response.transform(utf8.decoder).join();
  httpClient.close();
  return reply;
}

Depending on your use case, it may be more efficient to re-use the HttpClient, rather than keep creating a new one for each request. Todo - add some error handling ;-)

You can use arrows:

arrows(x,y-sd,x,y+sd, code=3, length=0.02, angle = 90)

I got this error when getting a value from NSUserDefaults. The following gives error:

let arr = defaults.objectForKey("myArray")

What fixed the error was to cast the type to the correct type stored in NSUserDefaults. The following gives no error:

let arr = defaults.objectForKey("myArray") as! Array<String>

Although System.Collections.Generic.Dictionary matches the tag "hashmap" and will work well in your example, it is not an exact equivalent of C++'s std::map - std::map is an ordered collection.

If ordering is important you should use SortedDictionary.

My main advice would be to steer clear of the HAVING clause (see below):

WITH HighEarners AS
     ( SELECT EmpId, DeptId
         FROM EMPLOYEE
        WHERE Salary > 1000 ), 
     DeptmentHighEarnerTallies AS 
     ( SELECT DeptId, COUNT(*) AS HighEarnerTally
         FROM HighEarners
        GROUP 
           BY DeptId )
SELECT DeptName
  FROM DEPARTMENT NATURAL JOIN DeptmentHighEarnerTallies
 WHERE HighEarnerTally > 2;

The very early SQL implementations lacked derived tables and HAVING was a workaround for one of its most obvious drawbacks (how to select on the result of a set function from the SELECT clause). Once derived tables had become a thing, the need for HAVING went away. Sadly, HAVING itself didn't go away (and never will) because nothing is ever removed from standard SQL. There is no need to learn HAVING and I encourage fledgling coders to avoid using this historical hangover.

update_attribute and update_attributes are similar, but with one big difference: update_attribute does not run validations.

Also:

• update_attribute is used to update record with single attribute.

  Model.update_attribute(:column_name, column_value1)
  

• update_attributes is used to update record with multiple attributes.

  Model.update_attributes(:column_name1 => column_value1, :column_name2 => column_value2, ...)
  

These two methods are really easy to confuse given their similar names and works. Therefore, update_attribute is being removed in favor of update_column.

Now, in Rails4 you can use Model.update_column(:column_name, column_value) at the place of Model.update_attribute(:column_name, column_value)

As you can see, the code public Circle(double r).... how is that different from what I did in mine with public CircleR(double r)? For whatever reason, no error is given in the code from the book, however mine says there is an error there.

When defining constructors of a class, they should have the same name as its class. Thus the following code

public class Circle
{ 
    //This part is called the constructor and lets us specify the radius of a  
    //particular circle. 
  public Circle(double r) 
  { 
   radius = r; 
  }
 ....
} 

is correct while your code

public class Circle
{
    private double radius;
    public CircleR(double r)
    {
        radius = r;
    }
    public diameter()
    {
       double d = radius * 2;
       return d;
    }
}

is wrong because your constructor has different name from its class. You could either follow the same code from the book and change your constructor from

public CircleR(double r) 

to

public Circle(double r)

or (if you really wanted to name your constructor as CircleR) rename your class to CircleR.

So your new class should be

public class CircleR
{
    private double radius;
    public CircleR(double r)
    {
        radius = r;
    }
    public double diameter()
    {
       double d = radius * 2;
       return d;
    }
}

I also added the return type double in your method as pointed out by Froyo and John B.

Refer to this article about constructors.

DateTime is a DataType which is used to store both Date and Time. But it provides Properties to get the Date Part.

You can get the Date part from Date Property.

http://msdn.microsoft.com/en-us/library/system.datetime.date.aspx

DateTime date1 = new DateTime(2008, 6, 1, 7, 47, 0);
Console.WriteLine(date1.ToString());

// Get date-only portion of date, without its time.
DateTime dateOnly = date1.Date;
// Display date using short date string.
Console.WriteLine(dateOnly.ToString("d"));
// Display date using 24-hour clock.
Console.WriteLine(dateOnly.ToString("g"));
Console.WriteLine(dateOnly.ToString("MM/dd/yyyy HH:mm"));   
// The example displays the following output to the console:
//       6/1/2008 7:47:00 AM
//       6/1/2008
//       6/1/2008 12:00 AM
//       06/01/2008 00:00

It is always a good idea to use existing solutions that are being supported by a lot of high-level developers. The most popular one is https://github.com/cocur/slugify. First of all, it supports more than one language, and it is being updated.

If you do not want to use the whole package, you can copy the part that you need.

When do I need to declare them myself?

The Rule of Three states that if you declare any of a

1. copy constructor
2. copy assignment operator
3. destructor

then you should declare all three. It grew out of the observation that the need to take over the meaning of a copy operation almost always stemmed from the class performing some kind of resource management, and that almost always implied that

• whatever resource management was being done in one copy operation probably needed to be done in the other copy operation and

• the class destructor would also be participating in management of the resource (usually releasing it). The classic resource to be managed was memory, and this is why all Standard Library classes that manage memory (e.g., the STL containers that perform dynamic memory management) all declare “the big three”: both copy operations and a destructor.

A consequence of the Rule of Three is that the presence of a user-declared destructor indicates that simple member wise copy is unlikely to be appropriate for the copying operations in the class. That, in turn, suggests that if a class declares a destructor, the copy operations probably shouldn’t be automatically generated, because they wouldn’t do the right thing. At the time C++98 was adopted, the significance of this line of reasoning was not fully appreciated, so in C++98, the existence of a user declared destructor had no impact on compilers’ willingness to generate copy operations. That continues to be the case in C++11, but only because restricting the conditions under which the copy operations are generated would break too much legacy code.

How can I prevent my objects from being copied?

Declare copy constructor & copy assignment operator as private access specifier.

class MemoryBlock
{
public:

//code here

private:
MemoryBlock(const MemoryBlock& other)
{
   cout<<"copy constructor"<<endl;
}

// Copy assignment operator.
MemoryBlock& operator=(const MemoryBlock& other)
{
 return *this;
}
};

int main()
{
   MemoryBlock a;
   MemoryBlock b(a);
}

In C++11 onwards you can also declare copy constructor & assignment operator deleted

class MemoryBlock
{
public:
MemoryBlock(const MemoryBlock& other) = delete

// Copy assignment operator.
MemoryBlock& operator=(const MemoryBlock& other) =delete
};


int main()
{
   MemoryBlock a;
   MemoryBlock b(a);
}

We can read properties file in spring boot using 3 way

1. Read value from application.properties Using @Value

map key as

public class EmailService {

 @Value("${email.username}")
 private String username;

}

2. Read value from application.properties Using @ConfigurationProperties

In this we will map prefix of key using ConfigurationProperties and key name is same as field of class

  @Component
   @ConfigurationProperties("email")
    public class EmailConfig {

        private String   username;
    }

3. Read application.properties Using using Environment object

public class EmailController {

@Autowired
private Environment env;

@GetMapping("/sendmail")
public void sendMail(){     
    System.out.println("reading value from application properties file  using Environment ");
    System.out.println("username ="+ env.getProperty("email.username"));
    System.out.println("pwd ="+ env.getProperty("email.pwd"));
}

I recommend you create an enum for your car colours instead of using Strings and the natural ordering of the enum will be the order in which you declare the constants.

public enum PaintColors {
    SILVER, BLUE, MAGENTA, RED
}

and

 static class ColorComparator implements Comparator<CarSort>
 {
     public int compare(CarSort c1, CarSort c2)
     {
         return c1.getColor().compareTo(c2.getColor());
     }
 }

You change the String to PaintColor and then in main your car list becomes:

carList.add(new CarSort("Ford Figo",PaintColor.SILVER));

...

Collections.sort(carList, new ColorComparator());

- (NSInteger)tableView:(UITableView *)theTableView numberOfRowsInSection:(NSInteger)section
{
    return 1;
}

- (UITableViewCell *)tableView:(UITableView *)theTableView  cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"HistoryCell";

    UITableViewCell *cell = (UITableViewCell *)[theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }
    cell.descriptionLabel.text = @"Testing";
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Code for selection.
}

these are UITableView delegate methods.

I'd try the following steps:

1) Check if there is a Byte Order Mark

2) Check if the file is valid UTF8

3) Use the local "ANSI" codepage (ANSI as Microsoft defines it)

Step 2 works because most non ASCII sequences in codepages other that UTF8 are not valid UTF8.

I have ran into this when doing ajax forms where I include multiple field sets. Taking for example an employment application. I start out with one professional reference set and I have a button that says "Add More". This does an ajax call with a $count parameter to include the input set again (name, contact, phone.. etc) This works fine on first page call as I do something like:

<?php 
include('references.php');`
?>

User presses a button that makes an ajax call ajax('references.php?count=1'); Then inside the references.php file I have something like:

<?php
$count = isset($_GET['count']) ? $_GET['count'] : 0;
?>

I also have other dynamic includes like this throughout the site that pass parameters. The problem happens when the user presses submit and there is a form error. So now to not duplicate code to include those extra field sets that where dynamically included, i created a function that will setup the include with the appropriate GET params.

<?php

function include_get_params($file) {
  $parts = explode('?', $file);
  if (isset($parts[1])) {
    parse_str($parts[1], $output);
    foreach ($output as $key => $value) {
      $_GET[$key] = $value;
    }
  }
  include($parts[0]);
}
?>

The function checks for query params, and automatically adds them to the $_GET variable. This has worked pretty good for my use cases.

Here is an example on the form page when called:

<?php
// We check for a total of 12
for ($i=0; $i<12; $i++) {
  if (isset($_POST['references_name_'.$i]) && !empty($_POST['references_name_'.$i])) {
   include_get_params(DIR .'references.php?count='. $i);
 } else {

}
?>

Just another example of including GET params dynamically to accommodate certain use cases. Hope this helps. Please note this code isn't in its complete state but this should be enough to get anyone started pretty good for their use case.

Much has changed for MySQL 8. I've found the following modification of the MySQL 8.0 "How to Reset the Root Password" documentation works with Mac OS X.

Create a temp file $HOME/mysql.root.txt with the SQL to update the root password:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<new-password>';

This uses mysql_native_password to avoid the Authentication plugin 'caching_sha2_password' cannot be loaded error, which I get if I omit the option.

Stop the server, start with an --init-file option to set the root password, then restart the server:

mysql.server stop mysql.server start --init-file=$HOME/mysql.root.txt mysql.server stop mysql.server start

Save the file lines in a list, then remove of the list the line you want to delete and write the remain lines to a new file

with open("file_name.txt", "r") as f:
    lines = f.readlines() 
    lines.remove("Line you want to delete\n")
    with open("new_file.txt", "w") as new_f:
        for line in lines:        
            new_f.write(line)

A simple solution:

Yes you can.

See the code from the following thread from 2007: PDF within a DIV

<div>
    <object data="test.pdf" type="application/pdf" width="300" height="200">
        alt : <a href="test.pdf">test.pdf</a>
    </object>
</div>

It uses <object>, which can be styled with CSS, and so you can float them, give them borders, etc.

(In the end, I edited my pdf files to remove large borders and converted them to jpg images.)

 byte[] byteArray = new byte[102400];
 base64String = Base64.encode(byteArray);

That code will encode 102400 bytes, no matter how much data you actually use in the array.

while ((bytesRead = fis.read(byteArray)) != -1)

You need to use the value of bytesRead somewhere.

Also, this may not read the whole file into the array in one go (it only reads as much as is in the I/O buffer), so your loop will probably not work, you may end up with half an image in your array.

I'd use Apache Commons IOUtils here:

 Base64.encode(FileUtils.readFileToByteArray(file));

Element objects have no .getroot() method. Drop that call, and the .tostring() call works:

xmlstr = ElementTree.tostring(et, encoding='utf8', method='xml')

You only need to use .getroot() if you have an ElementTree instance.

Other notes:

• This produces a bytestring, which in Python 3 is the bytes type.
  If you must have a str object, you have two options:

  1. Decode the resulting bytes value, from UTF-8: xmlstr.decode("utf8")

  2. Use encoding='unicode'; this avoids an encode / decode cycle:

     xmlstr = ElementTree.tostring(et, encoding='unicode', method='xml')
     

• If you wanted the UTF-8 encoded bytestring value or are using Python 2, take into account that ElementTree doesn't properly detect utf8 as the standard XML encoding, so it'll add a <?xml version='1.0' encoding='utf8'?> declaration. Use utf-8 or UTF-8 (with a dash) if you want to prevent this. When using encoding="unicode" no declaration header is added.

For Mac/Linux;

PYTHONPATH=/foo/bar/baz python somescript.py somecommand

For Windows, setup a wrapper pythonpath.bat;

@ECHO OFF
setlocal
set PYTHONPATH=%1
python %2 %3
endlocal

and call pythonpath.bat script file like;

pythonpath.bat /foo/bar/baz somescript.py somecommand

Below is a suggested approach to Question #1 which I use if I wish to use the ForEach-Object cmdlet. It does not directly answer the question because it does not EXIT the pipeline. However, it may achieve the desired effect in Q#1. The only drawback an amateur like myself can see is when processing large pipeline iterations.

    $zStop = $false
    (97..122) | Where-Object {$zStop -eq $false} | ForEach-Object {
    $zNumeric = $_
    $zAlpha = [char]$zNumeric
    Write-Host -ForegroundColor Yellow ("{0,4} = {1}" -f ($zNumeric, $zAlpha))
    if ($zAlpha -eq "m") {$zStop = $true}
    }
    Write-Host -ForegroundColor Green "My PSVersion = 5.1.18362.145"

I hope this is of use. Happy New Year to all.

def sort_np_array(x, column=None, flip=False):
    x = x[np.argsort(x[:, column])]
    if flip:
        x = np.flip(x, axis=0)
    return x

Array in the original question:

a = np.array([[9, 2, 3],
              [4, 5, 6],
              [7, 0, 5]])

The result of the sort_np_array function as expected by the author of the question:

sort_np_array(a, column=1, flip=False)

[2]: array([[7, 0, 5],
            [9, 2, 3],
            [4, 5, 6]])

@agilityvision's answer translated to Swift4/iOS11. I haven't used localized strings, but you can change that easily:

import UIKit

/** An alert controller that can be called without a view controller.
 Creates a blank view controller and presents itself over that
 **/
class AlertPlusViewController: UIAlertController {

    private var alertWindow: UIWindow?

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        self.alertWindow?.isHidden = true
        alertWindow = nil
    }

    func show() {
        self.showAnimated(animated: true)
    }

    func showAnimated(animated _: Bool) {

        let blankViewController = UIViewController()
        blankViewController.view.backgroundColor = UIColor.clear

        let window = UIWindow(frame: UIScreen.main.bounds)
        window.rootViewController = blankViewController
        window.backgroundColor = UIColor.clear
        window.windowLevel = UIWindowLevelAlert + 1
        window.makeKeyAndVisible()
        self.alertWindow = window

        blankViewController.present(self, animated: true, completion: nil)
    }

    func presentOkayAlertWithTitle(title: String?, message: String?) {

        let alertController = AlertPlusViewController(title: title, message: message, preferredStyle: .alert)
        let okayAction = UIAlertAction(title: "Ok", style: .default, handler: nil)
        alertController.addAction(okayAction)
        alertController.show()
    }

    func presentOkayAlertWithError(error: NSError?) {
        let title = "Error"
        let message = error?.localizedDescription
        presentOkayAlertWithTitle(title: title, message: message)
    }

MixEdit extension for Visual Studio allows you to do multiediting in the way you are describing. It supports multiple carets and multiple selections.

If you have a newer distro with a newer systemd (systemd version 236 or newer), you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME.

Long story:

In newer versions of systemd there is a relatively new option (the github request is from 2016 ish and the enhancement is merged/closed 2017 ish) where you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME. The file:path option is documented in the most recent systemd.exec man page.

This new feature is relatively new and so is not available for older distros like centos-7 (or any centos before that).

If you want to extend it just because you need Not-Swipeable behaviour, you dont need to do it. ViewPager2 provides nice property called : isUserInputEnabled

You can do it on a per file basis. Use the path attribute to include the filename

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <location path="YourFileNameHere.xml">
        <system.webServer>
            <staticContent>
                <clientCache cacheControlMode="DisableCache" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>

The problem is that your regex is a string, but html is bytes:

>>> type(html)
<class 'bytes'>

Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.

You can either decode the bytes to a string:

html = html.decode('ISO-8859-1')  # encoding may vary!
title = re.findall(pattern, html)  # no more error

Or use a bytes regex:

regex = rb'<title>(,+?)</title>'
#        ^

In this particular context, you can get the encoding from the response headers:

with urllib.request.urlopen(url) as response:
    encoding = response.info().get_param('charset', 'utf8')
    html = response.read().decode(encoding)

See the urlopen documentation for more details.

MVC is a controlled environment and MVVM is a reactive environment.

In a controlled environment you should have less code and a common source of logic; which should always live within the controller. However; in the web world MVC easily gets divided into view creation logic and view dynamic logic. Creation lives on the server and dynamic lives on the client. You see this a lot with ASP.NET MVC combined with AngularJS whereas the server will create a View and pass in a Model and send it to the client. The client will then interact with the View in which case AngularJS steps in to as a local controller. Once submitted the Model or a new Model is passed back to the server controller and handled. (Thus the cycle continues and there are a lot of other translations of this handling when working with sockets or AJAX etc but over all the architecture is identical.)

MVVM is a reactive environment meaning you typically write code (such as triggers) that will activate based on some event. In XAML, where MVVM thrives, this is all easily done with the built in databinding framework BUT as mentioned this will work on any system in any View with any programming language. It is not MS specific. The ViewModel fires (usually a property changed event) and the View reacts to it based on whatever triggers you create. This can get technical but the bottom line is the View is stateless and without logic. It simply changes state based on values. Furthermore, ViewModels are stateless with very little logic, and Models are the State with essentially Zero logic as they should only maintain state. I describe this as application state (Model), state translator (ViewModel), and then the visual state / interaction (View).

In an MVC desktop or client side application you should have a Model, and the Model should be used by the Controller. Based on the Model the controller will modify the View. Views are usually tied to Controllers with Interfaces so that the Controller can work with a variety of Views. In ASP.NET the logic for MVC is slightly backwards on the server as the Controller manages the Models and passes the Models to a selected View. The View is then filled with data based on the model and has it's own logic (usually another MVC set such as done with AngularJS). People will argue and get this confused with application MVC and try to do both at which point maintaining the project will eventually become a disaster. ALWAYS put the logic and control in one location when using MVC. DO NOT write View logic in the code behind of the View (or in the View via JS for web) to accommodate Controller or Model data. Let the Controller change the View. The ONLY logic that should live in a View is whatever it takes to create and run via the Interface it's using. An example of this is submitting a username and password. Whether desktop or web page (on client) the Controller should handle the submit process whenever the View fires the Submit action. If done correctly you can always find your way around an MVC web or local app easily.

MVVM is personally my favorite as it's completely reactive. If a Model changes state the ViewModel listens and translates that state and that's it!!! The View is then listening to the ViewModel for state change and it also updates based on the translation from the ViewModel. Some people call it pure MVVM but there's really only one and I don't care how you argue it and it's always Pure MVVM where the View contains absolutely no logic.

Here's a slight example: Let's say the you want to have a menu slide in on a button press. In MVC you will have a MenuPressed action in your interface. The Controller will know when you click the Menu button and then tell the View to slide in the Menu based on another Interface method such as SlideMenuIn. A round trip for what reason? Incase the Controller decides you can't or wants to do something else instead that's why. The Controller should be in charge of the View with the View doing nothing unless the Controller says so. HOWEVER; in MVVM the slide menu in animation should be built in and generic and instead of being told to slide it in will do so based on some value. So it listens to the ViewModel and when the ViewModel says, IsMenuActive = true (or however) the animation for that takes place. Now, with that said I want to make another point REALLY CLEAR and PLEASE pay attention. IsMenuActive is probably BAD MVVM or ViewModel design. When designing a ViewModel you should never assume a View will have any features at all and just pass translated model state. That way if you decide to change your View to remove the Menu and just show the data / options another way, the ViewModel doesn't care. So how would you manage the Menu? When the data makes sense that's how. So, one way to do this is to give the Menu a list of options (probably an array of inner ViewModels). If that list has data, the Menu then knows to open via the trigger, if not then it knows to hide via the trigger. You simply have data for the menu or not in the ViewModel. DO NOT decide to show / hide that data in the ViewModel.. simply translate the state of the Model. This way the View is completely reactive and generic and can be used in many different situations.

All of this probably makes absolutely no sense if you're not already at least slightly familiar with the architecture of each and learning it can be very confusing as you'll find ALOT OF BAD information on the net.

So... things to keep in mind to get this right. Decide up front how to design your application and STICK TO IT.

If you do MVC, which is great, then make sure you Controller is manageable and in full control of your View. If you have a large View consider adding controls to the View that have different Controllers. JUST DON'T cascade those controllers to different controllers. Very frustrating to maintain. Take a moment and design things separately in a way that will work as separate components... And always let the Controller tell the Model to commit or persist storage. The ideal dependency setup for MVC in is View ? Controller ? Model or with ASP.NET (don't get me started) Model ? View ? Controller ? Model (where Model can be the same or a totally different Model from Controller to View) ...of course the only need to know of Controller in View at this point is mostly for endpoint reference to know where back to pass a Model.

If you do MVVM, I bless your kind soul, but take the time to do it RIGHT! Do not use interfaces for one. Let your View decide how it's going to look based on values. Play with the View with Mock data. If you end up having a View that is showing you a Menu (as per the example) even though you didn't want it at the time then GOOD. You're view is working as it should and reacting based on the values as it should. Just add a few more requirements to your trigger to make sure this doesn't happen when the ViewModel is in a particular translated state or command the ViewModel to empty this state. In your ViewModel DO NOT remove this with internal logic either as if you're deciding from there whether or not the View should see it. Remember you can't assume there is a menu or not in the ViewModel. And finally, the Model should just allow you to change and most likely store state. This is where validation and all will occur; for example, if the Model can't modify the state then it will simply flag itself as dirty or something. When the ViewModel realizes this it will translate what's dirty, and the View will then realize this and show some information via another trigger. All data in the View can be binded to the ViewModel so everything can be dynamic only the Model and ViewModel has absolutely no idea about how the View will react to the binding. As a matter of fact the Model has no idea of a ViewModel either. When setting up dependencies they should point like so and only like so View ? ViewModel ? Model (and a side note here... and this will probably get argued as well but I don't care... DO NOT PASS THE MODEL to the VIEW unless that MODEL is immutable; otherwise wrap it with a proper ViewModel. The View should not see a model period. I give a rats crack what demo you've seen or how you've done it, that's wrong.)

Here's my final tip... Look at a well designed, yet very simple, MVC application and do the same for an MVVM application. One will have more control with limited to zero flexibility while the other will have no control and unlimited flexibility.

A controlled environment is good for managing the entire application from a set of controllers or (a single source) while a reactive environment can be broken up into separate repositories with absolutely no idea of what the rest of the application is doing. Micro managing vs free management.

If I haven't confused you enough try contacting me... I don't mind going over this in full detail with illustration and examples.

At the end of the day we're all programmers and with that anarchy lives within us when coding... So rules will be broken, theories will change, and all of this will end up hog wash... But when working on large projects and on large teams, it really helps to agree on a design pattern and enforce it. One day it will make the small extra steps taken in the beginning become leaps and bounds of savings later.

Use this code to easy get Date & Time :

package date.time;

import java.text.SimpleDateFormat;    
import java.util.Date;

public class DateTime {

    public static void main(String[] args) {
        SimpleDateFormat dnt = new SimpleDateFormat("dd/MM/yy :: HH:mm:ss");
        Date date = new Date();
        System.out.println("Today Date & Time at Now :"+dnt.format(date));  
    } 
}

Are you trying to mimic a click on a button when the enter key is pressed? If so you may need to use the trigger syntax.

Try changing

$('input[name = butAssignProd]').click();

to

$('input[name = butAssignProd]').trigger("click");

If this isn't the problem then try taking a second look at your key capture syntax by looking at the solutions in this post: jQuery Event Keypress: Which key was pressed?

Using BroadcastReceiver

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // something
    // for home listen
    InnerRecevier innerReceiver = new InnerRecevier();
    IntentFilter intentFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
    registerReceiver(innerReceiver, intentFilter);

}



// for home listen
class InnerRecevier extends BroadcastReceiver {

    final String SYSTEM_DIALOG_REASON_KEY = "reason";
    final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (Intent.ACTION_CLOSE_SYSTEM_DIALOGS.equals(action)) {
            String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);
            if (reason != null) {
                if (reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {
                    // home is Pressed
                }
            }
        }
    }
}

1 - Open the files '.vbox' and '.vbox-prev' (if exist) files in any text editor and replace the first character of HardDisk uuid (take note to revert this change on step 6)

Example: nano /home/virtualbox/WindowsServer/WindowsServer.vbox

Change:

<HardDisks>
        <HardDisk uuid="{3ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>

To:

<HardDisks>
        <HardDisk uuid="{2ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>

2 - Reboot machine

4 - Stop Virtual Machine (if started)

5 - On terminal:

su vbox
cd /home/virtualbox/WindowsServer/
VBoxManage modifyhd WindowsServer.vdi --resize SIZE
exit
exit

change SIZE for a number in Megabytes, example 80000 (80GB)

6 - Open again the files '.vbox' and '.vbox-prev' (if exist) files in any text editor and replace the first character of HardDisk uuid whith the original value

Example: nano /home/virtualbox/WindowsServer/WindowsServer.vbox

Change:

<HardDisks>
        <HardDisk uuid="{2ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>

To:

<HardDisks>
        <HardDisk uuid="{3ebaa9b6-8318-4b81-b853-8f30dd278bdc}" location="/home/virtualbox/WindowsServer/WindowsServer.vdi" format="VDI" type="Normal"/>

7 - Reboot machine

The problem, as stated in your logs, is 2 dependencies trying to use different versions of 3rd dependency. Add one of the following to the app-gradle file:

androidTestCompile 'com.google.code.findbugs:jsr305:2.0.1'
androidTestCompile 'com.google.code.findbugs:jsr305:1.3.9'

You can use DataFrame.fillna or Series.fillna which will replace the Python object None, not the string 'None'.

import pandas as pd
import numpy as np

For dataframe:

df = df.fillna(value=np.nan)

For column or series:

df.mycol.fillna(value=np.nan, inplace=True)

Hi I needed to do the same thing! Don't ask why but I was generating a html using python and needed a way to loop through items in a list and have each item take on a row of its own WITHIN A SINGLE CELL of a table.

I found that the br tag worked well for me. For example:

<!DOCTYPE html>
<HTML>
    <HEAD>
        <TITLE></TITLE>
    </HEAD>
    <BODY>
  <TABLE>
            <TR>
                <TD>
                    item 1 <BR>
                    item 2 <BR>
                    item 3 <BR>
                    item 4 <BR>
                </TD>
            </TR>
        </TABLE>
  </BODY>

This will produce the output that I wanted.

Do it simply by adding a class to the body:

.stop-scrolling {
  height: 100%;
  overflow: hidden;
}

Add the class then remove when you want to re-enable scrolling, tested in IE, FF, Safari and Chrome.

$('body').addClass('stop-scrolling')

For mobile devices, you'll need to handle the touchmove event:

$('body').bind('touchmove', function(e){e.preventDefault()})

And unbind to re-enable scrolling. Tested in iOS6 and Android 2.3.3

$('body').unbind('touchmove')

You can add a reference to System.Configuration in your project and then:

using System.Configuration;

then

string sValue = ConfigurationManager.AppSettings["BatchFile"];

with an app.config file like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <appSettings>
       <add key="BatchFile" value="blah.bat" />
   </appSettings>
</configuration>

You could write a function template back that delegates to the member function for ordinary containers and a normal function that implements the missing functionality for strings:

template <typename C>
typename C::reference back(C& container)
{
    return container.back();
}

template <typename C>
typename C::const_reference back(const C& container)
{
    return container.back();
}

char& back(std::string& str)
{
    return *(str.end() - 1);
}

char back(const std::string& str)
{
    return *(str.end() - 1);
}

Then you can just say back(foo) without worrying whether foo is a string or a vector.

It's very simple. Git doesn't care about what's the name of its directory. It only cares what's inside. So you can simply do:

# copy the directory into newrepo dir that exists already (else create it)
$ cp -r gitrepo1 newrepo

# remove .git from old repo to delete all history and anything git from it
$ rm -rf gitrepo1/.git

Note that the copy is quite expensive if the repository is large and with a long history. You can avoid it easily too:

# move the directory instead
$ mv gitrepo1 newrepo

# make a copy of the latest version
# Either:
$ mkdir gitrepo1; cp -r newrepo/* gitrepo1/  # doesn't copy .gitignore (and other hidden files)

# Or:
$ git clone --depth 1 newrepo gitrepo1; rm -rf gitrepo1/.git

# Or (look further here: http://stackoverflow.com/q/1209999/912144)
$ git archive --format=tar --remote=<repository URL> HEAD | tar xf -

Once you create newrepo, the destination to put gitrepo1 could be anywhere, even inside newrepo if you want it. It doesn't change the procedure, just the path you are writing gitrepo1 back.

This bug is filed here. This is a bug of android devices having API level less than 12. You've to put correct versions of your layouts in drawable-v12 folder which will be used for API level 12 or higher. And an erroneous version(corners switched/reversed) of the same layout will be put in the default drawable folder which will be used by the devices having API level less than 12.

For example: I had to design a button with rounded corner at bottom-right.

In 'drawable' folder - button.xml: I had to make bottom-left corner rounded.

<shape>
    <corners android:bottomLeftRadius="15dp"/>
</shape>

In 'drawable-v12' folder - button.xml: Correct version of the layout was placed here to be used for API level 12 or higher.

<shape>
    <corners android:bottomLeftRadius="15dp"/>
</shape>

public int getAge(Date dateOfBirth)

        throw new IllegalArgumentException("Can't be born in the future");
    }

    int age = now.get(Calendar.YEAR) - dob.get(Calendar.YEAR);

    if (now.get(Calendar.DAY_OF_YEAR) < dob.get(Calendar.DAY_OF_YEAR))

In general custom audit (creating various tables) is a bad option. Database/table triggers can be disabled to skip some log activities. Custom audit tables can be tampered. Exceptions can take place that will bring down application. Not to mentions difficulties designing a robust solution. So far I see a very simple cases in this discussion. You need a complete separation from current database and from any privileged users(DBA, Developers). Every mainstream RDBMSs provide audit facilities that even DBA not able to disable, tamper in secrecy. Therefore, provided audit capability by RDBMS vendor must be the first option. Other option would be 3rd party transaction log reader or custom log reader that pushes decomposed information into messaging system that ends up in some forms of Audit Data Warehouse or real time event handler. In summary: Solution Architect/"Hands on Data Architect" needs to involve in destining such a system based on requirements. It is usually too serious stuff just to hand over to a developers for solution.

update: Copied material that was on the R wiki at http://rwiki.sciviews.org/doku.php?id=tips:graphics-base:2yaxes, link now broken: also available from the wayback machine

Two different y axes on the same plot

(some material originally by Daniel Rajdl 2006/03/31 15:26)

Please note that there are very few situations where it is appropriate to use two different scales on the same plot. It is very easy to mislead the viewer of the graphic. Check the following two examples and comments on this issue (example1, example2 from Junk Charts), as well as this article by Stephen Few (which concludes “I certainly cannot conclude, once and for all, that graphs with dual-scaled axes are never useful; only that I cannot think of a situation that warrants them in light of other, better solutions.”) Also see point #4 in this cartoon ...

If you are determined, the basic recipe is to create your first plot, set par(new=TRUE) to prevent R from clearing the graphics device, creating the second plot with axes=FALSE (and setting xlab and ylab to be blank – ann=FALSE should also work) and then using axis(side=4) to add a new axis on the right-hand side, and mtext(...,side=4) to add an axis label on the right-hand side. Here is an example using a little bit of made-up data:

set.seed(101)
x <- 1:10
y <- rnorm(10)
## second data set on a very different scale
z <- runif(10, min=1000, max=10000) 
par(mar = c(5, 4, 4, 4) + 0.3)  # Leave space for z axis
plot(x, y) # first plot
par(new = TRUE)
plot(x, z, type = "l", axes = FALSE, bty = "n", xlab = "", ylab = "")
axis(side=4, at = pretty(range(z)))
mtext("z", side=4, line=3)

twoord.plot() in the plotrix package automates this process, as does doubleYScale() in the latticeExtra package.

Another example (adapted from an R mailing list post by Robert W. Baer):

## set up some fake test data
time <- seq(0,72,12)
betagal.abs <- c(0.05,0.18,0.25,0.31,0.32,0.34,0.35)
cell.density <- c(0,1000,2000,3000,4000,5000,6000)

## add extra space to right margin of plot within frame
par(mar=c(5, 4, 4, 6) + 0.1)

## Plot first set of data and draw its axis
plot(time, betagal.abs, pch=16, axes=FALSE, ylim=c(0,1), xlab="", ylab="", 
   type="b",col="black", main="Mike's test data")
axis(2, ylim=c(0,1),col="black",las=1)  ## las=1 makes horizontal labels
mtext("Beta Gal Absorbance",side=2,line=2.5)
box()

## Allow a second plot on the same graph
par(new=TRUE)

## Plot the second plot and put axis scale on right
plot(time, cell.density, pch=15,  xlab="", ylab="", ylim=c(0,7000), 
    axes=FALSE, type="b", col="red")
## a little farther out (line=4) to make room for labels
mtext("Cell Density",side=4,col="red",line=4) 
axis(4, ylim=c(0,7000), col="red",col.axis="red",las=1)

## Draw the time axis
axis(1,pretty(range(time),10))
mtext("Time (Hours)",side=1,col="black",line=2.5)  

## Add Legend
legend("topleft",legend=c("Beta Gal","Cell Density"),
  text.col=c("black","red"),pch=c(16,15),col=c("black","red"))

Similar recipes can be used to superimpose plots of different types – bar plots, histograms, etc..

I think the answer may be easier to understand like this:

$('#empid').on('change',function() {_x000D_
  alert($(this).val());_x000D_
  console.log($(this).val());_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>_x000D_
<select id="empid" name="empname" multiple="multiple">_x000D_
  <option value="0">Potato</option>_x000D_
  <option value="1">Carrot</option>_x000D_
  <option value="2">Apple</option>_x000D_
  <option value="3">Raisins</option>_x000D_
  <option value="4">Peanut</option>_x000D_
</select>_x000D_
<br />_x000D_
Hold CTRL / CMD for selecting multiple fields

If you select "Carrot" and "Raisins" in the list, the output will be "1,3".

This works for me https://www.nuget.org/packages/ASquare.WindowsTaskScheduler/

It is nicely designed Fluent API.

//This will create Daily trigger to run every 10 minutes for a duration of 18 hours
SchedulerResponse response = WindowTaskScheduler
    .Configure()
    .CreateTask("TaskName", "C:\\Test.bat")
    .RunDaily()
    .RunEveryXMinutes(10)
    .RunDurationFor(new TimeSpan(18, 0, 0))
    .SetStartDate(new DateTime(2015, 8, 8))
    .SetStartTime(new TimeSpan(8, 0, 0))
    .Execute();

Usually with printf (or one of its cousins) using the %x format specifier.

If you would like to output array within string using puts, you will get the same result as if you were using print:

puts "#{[0, 1, nil]}":
[0, 1, nil]

But if not withing a quoted string then yes. The only difference is between new line when we use puts.

If you don't mind using absolute positioning, you can position your background image, and then add an overlay using opacity.

div {
    width:50px;
    height:50px;
    background:   url('http://images1.wikia.nocookie.net/__cb20120626155442/adventuretimewithfinnandjake/images/6/67/Link.gif');
    position:absolute;
    left:0;
    top:0;
}

.overlay {
   background:red;
   opacity:.5;
}

Use the index to get desired node if xpath is complicated or more than one node present with same xpath.

Ex :

(//bookstore[@location = 'US'])[index]

You can give the number which node you want.

You can use either h() or html_escape(), but most people use h() by convention. h() is short for html_escape() in rails.

In your controller:

@stuff = "<b>Hello World!</b>"

In your view:

<%=h @stuff %>

If you view the HTML source: you will see the output without actually bolding the data. I.e. it is encoded as <b>Hello World!</b>.

It will appear an be displayed as <b>Hello World!</b>

The options for popen can be used in call

args, 
bufsize=0, 
executable=None, 
stdin=None, 
stdout=None, 
stderr=None, 
preexec_fn=None, 
close_fds=False, 
shell=False, 
cwd=None, 
env=None, 
universal_newlines=False, 
startupinfo=None, 
creationflags=0

So...

subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml",  "/tmp/video_xml"], stdout=myoutput)

Then you can do what you want with myoutput (which would need to be a file btw).

Also, you can do something closer to a piped output like this.

dmesg | grep hda

would be:

p1 = Popen(["dmesg"], stdout=PIPE)
p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]

There's plenty of lovely, useful info on the python manual page.

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

I'd use wildcard searching.

where <field> like '%[ab]%'

It isn't regex, but it does a good job. You can also do variants like <field> like 'sim[oa]ns' -- which will match simons, and simans...

Depnding on your collation you may or may not have to include case data, like '%[aAbB]%'

As mentioned elsewhere be prepared for a wait since indexes are out of the question when you're doing contains searching.

I was using this two lines in the url and the template from the admin what i was changing to my need

• Updated Nov 2019 (appended).

I routinely use several Anaconda-installed virtual environments (venv). This code snippet/examples enables you to determine whether or not you are in a venv (or your system environment), and to also require a specific venv for your script.

Add to Python script (code snippet):

# ----------------------------------------------------------------------------
# Want script to run in Python 3.5 (has required installed OpenCV, imutils, ... packages):
import os

# First, see if we are in a conda venv { py27: Python 2.7 | py35: Python 3.5 | tf: TensorFlow | thee : Theano }
try:
   os.environ["CONDA_DEFAULT_ENV"]
except KeyError:
   print("\tPlease set the py35 { p3 | Python 3.5 } environment!\n")
   exit()

# If we are in a conda venv, require the p3 venv:
if os.environ['CONDA_DEFAULT_ENV'] != "py35":
    print("\tPlease set the py35 { p3 | Python 3.5 } environment!\n")
    exit()

# See also:
# Python: Determine if running inside virtualenv
# http://stackoverflow.com/questions/1871549/python-determine-if-running-inside-virtualenv  
# [ ... SNIP! ... ]

Example:

$ p2
  [Anaconda Python 2.7 venv (source activate py27)]

(py27) $ python  webcam_.py
    Please set the py35 { p3 | Python 3.5 } environment!

(py27) $ p3
  [Anaconda Python 3.5 venv (source activate py35)]

(py35) $ python  webcam.py -n50

    current env: py35
    processing (live): found 2 faces and 4 eyes in this frame
    threaded OpenCV implementation
    num_frames: 50
    webcam -- approx. FPS: 18.59
    Found 2 faces and 4 eyes!
(py35) $

Update 1 -- use in bash scripts:

You can also use this approach in bash scripts (e.g., those that must run in a specific virtual environment). Example (added to bash script):

if [ $CONDA_DEFAULT_ENV ]        ## << note the spaces (important in BASH)!
    then
        printf 'venv: operating in tf-env, proceed ...'
    else
        printf 'Note: must run this script in tf-env venv'
        exit
fi

Update 2 [Nov 2019]

• For simplicity, I like Matt's answer (https://stackoverflow.com/a/51245168/1904943).

Since my original post I've moved on from Anaconda venv (and Python itself has evolved viz-a-viz virtual environments).

Reexamining this issue, here is some updated Python code that you can insert to test that you are operating in a specific Python virtual environment (venv).

import os, re
try:
    if re.search('py37', os.environ['VIRTUAL_ENV']):
        pass
except KeyError:
    print("\n\tPlease set the Python3 venv [alias: p3]!\n")
    exit()

Here is some explanatory code.

In fact there is a way to use two or more models on one view without wrapping them in a class that contains both.

Using Employee as an example model:

@model Employee

Is actually treated like.

@{ var Model = ViewBag.model as Employee; }

So the View(employee) method is setting your model to the ViewBag and then the ViewEngine is casting it.

This means that,

ViewBag.departments = GetListOfDepartments();
    return View(employee);

Can be used like,

            @model  Employee
        @{
                var DepartmentModel = ViewBag.departments as List<Department>;
        }

Essentially, you can use whatever is in your ViewBag as a "Model" because that's how it works anyway. I'm not saying that this is architecturally ideal, but it is possible.

I don't know if it would work, but maybe you could break the page into columns using the multicol package.

\usepackage{multicol}

\begin{document}
\begin{multicols}{2}[Your list here]
\end{multicols}

@Chaibi Alaa, To make the user able to add only once, and move the marker; You can set the marker on first click and then just change the position on subsequent clicks.

var marker;

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});


function placeMarker(location) {

    if (marker == null)
    {
          marker = new google.maps.Marker({
             position: location,
             map: map

    } 
    else 
    {
        marker.setPosition(location); 
    } 
}

I was having this issue intermittently. Unbeknownst to me, BackboneJS was running on the page and replacing the element I was trying to click. My code looked like this.

driver.findElement(By.id("checkoutLink")).click();

Which is of course functionally the same as this.

WebElement checkoutLink = driver.findElement(By.id("checkoutLink"));
checkoutLink.click();

What would occasionally happen was the javascript would replace the checkoutLink element in between finding and clicking it, ie.

WebElement checkoutLink = driver.findElement(By.id("checkoutLink"));
// javascript replaces checkoutLink
checkoutLink.click();

Which rightfully led to a StaleElementReferenceException when trying to click the link. I couldn't find any reliable way to tell WebDriver to wait until the javascript had finished running, so here's how I eventually solved it.

new WebDriverWait(driver, timeout)
    .ignoring(StaleElementReferenceException.class)
    .until(new Predicate<WebDriver>() {
        @Override
        public boolean apply(@Nullable WebDriver driver) {
            driver.findElement(By.id("checkoutLink")).click();
            return true;
        }
    });

This code will continually try to click the link, ignoring StaleElementReferenceExceptions until either the click succeeds or the timeout is reached. I like this solution because it saves you having to write any retry logic, and uses only the built-in constructs of WebDriver.

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

I believe IE requires the H.264 or MPEG-4 codec, which it seems like you don't specify/include. You can always check for browser support by using HTML5Please and Can I use.... Both sites usually have very up-to-date information about support, polyfills, and advice on how to take advantage of new technology.

The base UINavigationController should have the below callback so that the child items can decide what orientation they want.

-(NSUInteger)supportedInterfaceOrientations {
    UIViewController *topVC = self.topViewController;
    return topVC.supportedInterfaceOrientations;
}

-(BOOL)shouldAutorotate {
   UIViewController *topVC = self.topViewController;
   return [topVC shouldAutorotate];
}

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

Live demo

Fixed: no need to use a setOnMenuItemClickListener. Just pressing the button, it creates and launches the activity through the intent.

Thanks a lot everybody for your help!

echo test > afile.txt

redirects stdout to afile.txt. This is the same as doing

echo test 1> afile.txt

To redirect stderr, you do:

echo test 2> afile.txt

>& is the syntax to redirect a stream to another file descriptor - 0 is stdin, 1 is stdout, and 2 is stderr.

You can redirect stdout to stderr by doing:

echo test 1>&2 # or echo test >&2

Or vice versa:

echo test 2>&1

So, in short... 2> redirects stderr to an (unspecified) file, appending &1 redirects stderr to stdout.

In C++ language the result of the subexpresison is never affected by the surrounding context (with some rare exceptions). This is one of the principles that the language carefully follows. The expression c = a / b contains of an independent subexpression a / b, which is interpreted independently from anything outside that subexpression. The language does not care that you later will assign the result to a double. a / b is an integer division. Anything else does not matter. You will see this principle followed in many corners of the language specification. That's juts how C++ (and C) works.

One example of an exception I mentioned above is the function pointer assignment/initialization in situations with function overloading

void foo(int);
void foo(double);

void (*p)(double) = &foo; // automatically selects `foo(fouble)`

This is one context where the left-hand side of an assignment/initialization affects the behavior of the right-hand side. (Also, reference-to-array initialization prevents array type decay, which is another example of similar behavior.) In all other cases the right-hand side completely ignores the left-hand side.

You can also rename remote tags without checking them out, by duplicate the old tag/branch to a new name and delete the old one, in a single git push command.

Remote tag rename / Remote branch ? tag conversion: (Notice: :refs/tags/)

git push <remote_name> <old_branch_or_tag>:refs/tags/<new_tag> :<old_branch_or_tag>

Remote branch rename / Remote tag ? branch conversion: (Notice: :refs/heads/)

git push <remote_name> <old_branch_or_tag>:refs/heads/<new_branch> :<old_branch_or_tag>

Output renaming a remote tag:

D:\git.repo>git push gitlab App%2012.1%20v12.1.0.23:refs/tags/App_12.1_v12.1.0.23 :App%2012.1%20v12.1.0.23

When you declare:

int column, row, index = 0;

Only index is set to zero.

However you can do the following:

int column, row, index;
column = index = row = 0;

But personally I prefer the following which has been pointed out.
It's a more readable form in my view.

int column = 0, row = 0, index = 0;

or

int column = 0;
int row = 0;
int index = 0;

C++11 standard on jumping over some initializations

JohannesD gave an explanation, now for the standards.

The C++11 N3337 standard draft 6.7 "Declaration statement" says:

3 It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps (87) from a point where a variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has scalar type, class type with a trivial default constructor and a trivial destructor, a cv-qualified version of one of these types, or an array of one of the preceding types and is declared without an initializer (8.5).

87) The transfer from the condition of a switch statement to a case label is considered a jump in this respect.

[ Example:

void f() {
   // ...
  goto lx;    // ill-formed: jump into scope of a
  // ...
ly:
  X a = 1;
  // ...
lx:
  goto ly;    // OK, jump implies destructor
              // call for a followed by construction
              // again immediately following label ly
}

— end example ]

As of GCC 5.2, the error message now says:

crosses initialization of

C

C allows it: c99 goto past initialization

The C99 N1256 standard draft Annex I "Common warnings" says:

2 A block with initialization of an object that has automatic storage duration is jumped into

3-right click on drawable and new drawable resource file just set root element to selector.

go to file and set "state_pressed"

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_pressed="true"android:drawable="@drawable/YourShape1"/>
<item android:state_pressed="false" android:drawable="@drawable/YourShape2"/>

</selector>

4-the end go to xml layout and set your Button background "your selector"

(sorry for my english weak)

use this command on your script file after copying it to Linux/Unix

perl -pi -e 's/\r//' scriptfilename

You can also pass value directly via URL.

If you want to call method public static void calling(string name){....}

then you should call usingHttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create("http://localhost:****/Report/calling?name=Priya); webrequest.Method = "GET"; webrequest.ContentType = "application/text";

Just make sure you are using ?Object = value in URL

getline is storing the entire line at once, which is not what you want. A simple fix is to have three variables and use cin to get them all. C++ will parse automatically at the spaces.

#include <iostream>
using namespace std;

int main() {
    string a, b, c;
    cin >> a >> b >> c;
    //now you have your three words
    return 0;
}

I don't know what particular "operation" you're talking about, so I can't help you there, but if it's changing characters, read up on string and indices. The C++ documentation is great. As for using namespace std; versus std:: and other libraries, there's already been a lot said. Try these questions on StackOverflow to start.

Try this :

$('.close-button').on('click', function(){
  $('.element').removeClass('grown');
  $('.element').addClass('spot');
});

$('.element').on('click', function(){
  $(this).removeClass('spot');
  $(this).addClass('grown');
});

I hope I understood your question.

Well, I don't understand why are you used transaction in case when you make a select.

Transaction is useful when you make changes (add, edit or delete) data from database.

Remove transaction unless you use insert, update or delete statements

I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.

this is a generic example let me know if this explains the point i mentioned

CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
    empName VARCHAR2(50);
    empSalary NUMBER(7,2);      
BEGIN
    UPDATE emp
    SET sal = sal + 1000
    WHERE empno = 7499
    RETURNING ename, sal
    INTO empName, empSalary;

    DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
    DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;

I ran into this as well and tried all of the other solutions. I did not have the .class file in my HTML folder, I only had the .java file. Once I added the .class file the program worked fine.

My blog will work 100 percent.

If you want to keep with the Pandas syntex this worked for me.

df = df[df.dt_mvmt.isNotNull()]

I needed to explicitly add POST in the CURL command:

curl -X POST http://<user>:<token>@<server>/safeRestart

I also have the SafeRestart Plugin installed, in case that makes a difference.

Assuming a list like below - and assuming some of the options were selected ... (this is a multi select, but this will also work on a single select.

<select multiple='multiple' id='selectListName'> 
    <option>1</option> 
    <option>2</option> 
    <option>3</option> 
    <option>4</option>
</select>

In some function called based on some event, the following code would clear all selected options.

$("#selectListName").prop('selectedIndex', -1);

This workaround works for me for VS 2019

Tools => Options

Then type Projects and solutions in the search box.

Select the Web Projects.

Then deselect the option below.

Stop debugger when browser window is closed, close browser when debugging stops.

This works for me. Hope this will help.

Add the following line at the top of the file that gives the error:

declare var require: any

The default System.Net.ServicePointManager.SecurityProtocol in both .NET 4.0/4.5 is SecurityProtocolType.Tls|SecurityProtocolType.Ssl3.

.NET 4.0 supports up to TLS 1.0 while .NET 4.5 supports up to TLS 1.2

However, an application targeting .NET 4.0 can still support up to TLS 1.2 if .NET 4.5 is installed in the same environment. .NET 4.5 installs on top of .NET 4.0, replacing System.dll.

I've verified this by observing the correct security protocol set in traffic with fiddler4 and by manually setting the enumerated values in a .NET 4.0 project:

ServicePointManager.SecurityProtocol = (SecurityProtocolType)192 |
(SecurityProtocolType)768 | (SecurityProtocolType)3072;

Reference:

namespace System.Net
{
    [System.Flags]
    public enum SecurityProtocolType
    {
       Ssl3 = 48,
       Tls = 192,
       Tls11 = 768,
       Tls12 = 3072,
    }
}

If you attempt the hack on an environment with ONLY .NET 4.0 installed, you will get the exception:

Unhandled Exception: System.NotSupportedException: The requested security protocol is not supported. at System.Net.ServicePointManager.set_SecurityProtocol(SecurityProtocolType v alue)

However, I wouldn't recommend this "hack" since a future patch, etc. may break it.*

Therefore, I've decided the best route to remove support for SSLv3 is to:

1. Upgrade all applications to .NET 4.5

2. Add the following to boostrapping code to override the default and future proof it:

   System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

*Someone correct me if this hack is wrong, but initial tests I see it works

The problem is in the file :

style.css - line 721

#sub_footer {
    background: url("../images/exterior/sub_footer.png") repeat-x;
    background: -moz-linear-gradient(0% 100% 90deg,#102c40, #091925);
    background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#091925), to(#102c40));
    -moz-box-shadow: 3px 3px 4px #999999;
    -webkit-box-shadow: 3px 3px 4px #999999;
    box-shadow: 3px 3px 4px #999999;
    padding-top:10px;
    font-size:9px;
    min-height:40px;
}

remove the lines :

-moz-box-shadow: 3px 3px 4px #999999;
-webkit-box-shadow: 3px 3px 4px #999999;
box-shadow: 3px 3px 4px #999999; 

This basically gives a shadow gradient only to the footer. In Firefox, it is the first line that is causing the problem.

Some might say that I'm a little off-topic, but here it is anyway:

You don't necessarily have to choose because of your string's content between:
echo "It's \"game\" time."; or echo 'It\'s "game" time.';

If you're familiar with the use of the english quotation marks, and the correct character for the apostrophe, you can use either double or single quotes, because it won't matter anymore:
echo "It’s “game” time."; and echo 'It’s “game” time.';

Of course you can also add variables if needed. Just don't forget that they get evaluated only when in double quotes!

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

Error message suggests that the client has closed the connection while the server is still trying to write out a response.

You should not used document.getElementByID because its work only for client side controls which ids are fixed . You should use jquery instead like below example.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>                                                                                                             
<div id="foo">
   <div class="bar"> 
          Hello world!
     </div>
</div>

use this :

$("[id^='foo']").find("[class^='bar']")

// do not forget to add script tags as above

if you want any remove edit any operation then just add "." behind and do the operations

Sometimes when I get stuck on this I hard code a path to project in the wsgi file like:

sys.path.append("/var/www/html/myproject")

application = get_wsgi_application()

It will work.

Edit to original answer: Even though this is answer (as of the time of this comment) is the selected answer, the original version of this answer is outdated.

I'm adding an update here to help others avoid getting sidetracked by this answer like I did.

As the other answer mentions, Ruby >= 2.5 added the Hash#slice method which was previously only available in Rails.

Example:

> { one: 1, two: 2, three: 3 }.slice(:one, :two)
=> {:one=>1, :two=>2}

End of edit. What follows is the original answer which I guess will be useful if you're on Ruby < 2.5 without Rails, although I imagine that case is pretty uncommon at this point.

If you're using Ruby, you can use the select method. You'll need to convert the key from a Symbol to a String to do the regexp match. This will give you a new Hash with just the choices in it.

choices = params.select { |key, value| key.to_s.match(/^choice\d+/) }

or you can use delete_if and modify the existing Hash e.g.

params.delete_if { |key, value| !key.to_s.match(/choice\d+/) }

or if it is just the keys and not the values you want then you can do:

params.keys.select { |key| key.to_s.match(/^choice\d+/) }

and this will give the just an Array of the keys e.g. [:choice1, :choice2, :choice3]

i'd suggest shorter and faster approach:

printf("%.2f", ((signed long)(fVal * 100) * 0.01f));

this way you won't overflow int, plus multiplication by 100 shouldn't influence the significand/mantissa itself, because the only thing that really is changing is exponent.

I found this more cleaner.

       Date start = new Date();
        //Waiting for 10 seconds
        Thread.sleep(10000);
        Date end = new Date();
        long diff = end.getTime() - start.getTime();
        String TimeTaken = String.format("[%s] hours : [%s] mins : [%s] secs",
                Long.toString(TimeUnit.MILLISECONDS.toHours(diff)), 
                TimeUnit.MILLISECONDS.toMinutes(diff),
                TimeUnit.MILLISECONDS.toSeconds(diff));
        System.out.println(String.format("Time taken %s", TimeTaken));

Output : Time taken [0] hours : [0] mins : [10] secs

localeCompare() is slow, so if you don't care about the "correct" ordering of non-English-character strings, try your original method or the cleaner-looking:

str1 < str2 ? -1 : +(str1 > str2)

This is an order of magnitude faster than localeCompare() on my machine.

The + ensures that the answer is always numeric rather than boolean.

Try the below code. I am using this code for opening a PDF file. You can use it for other files also.

File file = new File(Environment.getExternalStorageDirectory(),
                     "Report.pdf");
Uri path = Uri.fromFile(file);
Intent pdfOpenintent = new Intent(Intent.ACTION_VIEW);
pdfOpenintent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
pdfOpenintent.setDataAndType(path, "application/pdf");
try {
    startActivity(pdfOpenintent);
}
catch (ActivityNotFoundException e) {

}

If you want to open files, you can change the setDataAndType(path, "application/pdf"). If you want to open different files with the same intent, you can use Intent.createChooser(intent, "Open in...");. For more information, look at How to make an intent with multiple actions.

Best shown by example. String. 192.168.1.1 and a greedy regex \b.+\b You might think this would give you the 1st octet but is actually matches against the whole string. Why? Because the.+ is greedy and a greedy match matches every character in 192.168.1.1 until it reaches the end of the string. This is the important bit! Now it starts to backtrack one character at a time until it finds a match for the 3rd token (\b).

If the string a 4GB text file and 192.168.1.1 was at the start you could easily see how this backtracking would cause an issue.

To make a regex non greedy (lazy) put a question mark after your greedy search e.g

*?
??
+?

What happens now is token 2 (+?) finds a match, regex moves along a character and then tries the next token (\b) rather than token 2 (+?). So it creeps along gingerly.

I have seen systems that use Reflection and attributes on Properties or fields to maps DataReaders to objects. (A bit like what LinqToSql does.) They save a bit of typing and may reduce the number of errors when coding for DBNull etc. Once you cache the generated code they can be faster then most hand written code as well, so do consider the “high road” if you are doing this a lot.

See "A Defense of Reflection in .NET" for one example of this.

You can then write code like

class CustomerDTO  
{
    [Field("id")]
    public int? CustomerId;

    [Field("name")]
    public string CustomerName;
}

...

using (DataReader reader = ...)
{    
   List<CustomerDTO> customers = reader.AutoMap<CustomerDTO>()
                                    .ToList();
}

(AutoMap(), is an extension method)

@Stilgar, thanks for a great comment

If are able to you are likely to be better of using NHibernate, EF or Linq to Sql, etc However on old project (or for other (sometimes valid) reasons, e.g. “not invented here”, “love of stored procs” etc) It is not always possible to use a ORM, so a lighter weight system can be useful to have “up your sleeves”

If you every needed too write lots of IDataReader loops, you will see the benefit of reducing the coding (and errors) without having to change the architecture of the system you are working on. That is not to say it’s a good architecture to start with..

I am assuming that CustomerDTO will not get out of the data access layer and composite objects etc will be built up by the data access layer using the DTO objects.

A few years after I wrote this answer Dapper entered the world of .NET, it is likely to be a very good starting point for writing your onw AutoMapper, maybe it will completely remove the need for you to do so.

Outstream is not closed ... close the stream so that response goes back to test client. Hope this helps.

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

That's my personal short function

I'm surprised nobody mentioned diff -y to produce a side-by-side output, for example:

And in file3(different lines have a symbol | in middle):

(Update: August 2011)

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"

Java 7 regex named group support was presented back in September 2010 in Oracle's blog.

In the official release of Java 7, the constructs to support the named capturing group are:

• (?<name>capturing text) to define a named group "name"
• \k<name> to backreference a named group "name"
• ${name} to reference to captured group in Matcher's replacement string
• Matcher.group(String name) to return the captured input subsequence by the given "named group".

Other alternatives for pre-Java 7 were:

• Google named-regex (see John Hardy's answer)
  Gábor Lipták mentions (November 2012) that this project might not be active (with several outstanding bugs), and its GitHub fork could be considered instead.
• jregex (See Brian Clozel's answer)

(Original answer: Jan 2009, with the next two links now broken)

You can not refer to named group, unless you code your own version of Regex...

That is precisely what Gorbush2 did in this thread.

Regex2

(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:

only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.

Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)

Example:

String:

"TEST 123"

RegExp:

"(?<login>\\w+) (?<id>\\d+)"

Access

matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login

Replace

matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____ 

(extract from the implementation)

                    head = createGroup(false);
                    ((GroupTail)root).name = name.toString();

                    capturingGroup = true;
                    tail = root;
                    head.next = expr(tail);

                }

One downside of the solutions based on grid.arrange is that they make it difficult to label the plots with letters (A, B, etc.), as most journals require.

I wrote the cowplot package to solve this (and a few other) issues, specifically the function plot_grid():

library(cowplot)

iris1 <- ggplot(iris, aes(x = Species, y = Sepal.Length)) +
  geom_boxplot() + theme_bw()

iris2 <- ggplot(iris, aes(x = Sepal.Length, fill = Species)) +
  geom_density(alpha = 0.7) + theme_bw() +
  theme(legend.position = c(0.8, 0.8))

plot_grid(iris1, iris2, labels = "AUTO")

The object that plot_grid() returns is another ggplot2 object, and you can save it with ggsave() as usual:

p <- plot_grid(iris1, iris2, labels = "AUTO")
ggsave("plot.pdf", p)

Alternatively, you can use the cowplot function save_plot(), which is a thin wrapper around ggsave() that makes it easy to get the correct dimensions for combined plots, e.g.:

p <- plot_grid(iris1, iris2, labels = "AUTO")
save_plot("plot.pdf", p, ncol = 2)

(The ncol = 2 argument tells save_plot() that there are two plots side-by-side, and save_plot() makes the saved image twice as wide.)

For a more in-depth description of how to arrange plots in a grid see this vignette. There is also a vignette explaining how to make plots with a shared legend.

One frequent point of confusion is that the cowplot package changes the default ggplot2 theme. The package behaves that way because it was originally written for internal lab uses, and we never use the default theme. If this causes problems, you can use one of the following three approaches to work around them:

1. Set the theme manually for every plot. I think it's good practice to always specify a particular theme for each plot, just like I did with + theme_bw() in the example above. If you specify a particular theme, the default theme doesn't matter.

2. Revert the default theme back to the ggplot2 default. You can do this with one line of code:

theme_set(theme_gray())

3. Call cowplot functions without attaching the package. You can also not call library(cowplot) or require(cowplot) and instead call cowplot functions by prepending cowplot::. E.g., the above example using the ggplot2 default theme would become:

## Commented out, we don't call this
# library(cowplot)

iris1 <- ggplot(iris, aes(x = Species, y = Sepal.Length)) +
  geom_boxplot()

iris2 <- ggplot(iris, aes(x = Sepal.Length, fill = Species)) +
  geom_density(alpha = 0.7) +
  theme(legend.position = c(0.8, 0.8))

cowplot::plot_grid(iris1, iris2, labels = "AUTO")

Updates:

• As of cowplot 1.0, the default ggplot2 theme is not changed anymore.
• As of ggplot2 3.0.0, plots can be labeled directly, see e.g. here.

You may already find your answer because it was some time ago you asked. But I tried to do something similar when coding ror. I wanted to run "rails server" in a new cmd window so I don't have to open a new cmd and then find my path again.

What I found out was to use the K switch like this:

start cmd /k echo Hello, World!

start before "cmd" will open the application in a new window and "/K" will execute "echo Hello, World!" after the new cmd is up.

You can also use the /C switch for something similar.

start cmd /C pause

This will then execute "pause" but close the window when the command is done. In this case after you pressed a button. I found this useful for "rails server", then when I shutdown my dev server I don't have to close the window after.

Use the following in your batch file:

start cmd.exe /c "more-batch-commands-here"

or

start cmd.exe /k "more-batch-commands-here"

/c Carries out the command specified by string and then terminates

/k Carries out the command specified by string but remains

The /c and /k options controls what happens once your command finishes running. With /c the terminal window will close automatically, leaving your desktop clean. With /k the terminal window will remain open. It's a good option if you want to run more commands manually afterwards.

Consult the cmd.exe documentation using cmd /? for more details.

Escaping Commands with White Spaces

The proper formatting of the command string becomes more complicated when using arguments with spaces. See the examples below. Note the nested double quotes in some examples.

Examples:

Run a program and pass a filename parameter:
CMD /c write.exe c:\docs\sample.txt

Run a program and pass a filename which contains whitespace:
CMD /c write.exe "c:\sample documents\sample.txt"

Spaces in program path:
CMD /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in program path + parameters:
CMD /c ""c:\Program Files\demo.cmd"" Parameter1 Param2
CMD /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch demo1 and demo2:
CMD /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

https://stackoverflow.com/a/44845810/10480776 @Edison D'souza's answer was exactly what I was looking for. However, it was only replacing the first occurrence of the string. Here was my solution to handling multiple <br/> tags:

<Typography style={{ whiteSpace: "pre-line" }}>
    {shortDescription.split("<br/>").join("\n")}
</Typography>

Assuming you have already downloaded Jdk 1.8. You have to make sure your eclipse version supports Jdk 1.8. Click on "Help" tab and then select "Check for Updates". Try again.

Right click the project and select properties Click the java compiler from the left and change to your required version Hope this helps

Simple use this great free online tool:

https://pratie.tomodea.dev/lab/icalendar/default.asp

You can initialize it just like any list:

public List<ContactNumber> ContactNumbers { get; set; }

public Human(int id)
{
    Id = id;
    ContactNumbers = new List<ContactNumber>();
}

public Human(int id, string address, string name) :this(id)
{
    Address = address;
    Name = name;
    // no need to initialize the list here since you're
    // already calling the single parameter constructor
}       

However, I would even go a step further and make the setter private since you often don't need to set the list, but just access/modify its contents:

public List<ContactNumber> ContactNumbers { get; private set; }

Based on this article titled "How can a batch file test existence of a directory" it's "not entirely reliable".

BUT I just tested this:

@echo off
IF EXIST %1\NUL goto print
ECHO not dir
pause
exit
:print
ECHO It's a directory
pause

and it seems to work

You can specify the default named parameter in the json.dumps() function:

json.dumps(obj, default=lambda x: x.__dict__)

Explanation:

Form the docs (2.7, 3.6):

``default(obj)`` is a function that should return a serializable version
of obj or raise TypeError. The default simply raises TypeError.

(Works on Python 2.7 and Python 3.x)

Note: In this case you need instance variables and not class variables, as the example in the question tries to do. (I am assuming the asker meant class instance to be an object of a class)

I learned this first from @phihag's answer here. Found it to be the simplest and cleanest way to do the job.

Updated html for the newer bootstrap

    .table-hover > tbody > tr.danger:hover > td {
     background-color: red !important;
}
.table-hover > tbody > tr.warning:hover > td {
     background-color: yellow !important;
}
.table-hover > tbody > tr.success:hover > td {
     background-color: blue !important;
}

I don't know why this old issue popped up today in the Bash tagged listings, but just in case for future researchers, keep in mind that you can avoid escaping by using ASCII codes of the chars you need to echo.

Example:

 echo -e "This is \x22\x27\x22\x27\x22text\x22\x27\x22\x27\x22"
 This is "'"'"text"'"'"

\x22 is the ASCII code (in hex) for double quotes and \x27 for single quotes. Similarly you can echo any character.

I suppose if we try to echo the above string with backslashes, we will need a messy two rows backslashed echo... :)

For variable assignment this is the equivalent:

 $ a=$'This is \x22text\x22'
 $ echo "$a"
 This is "text"

If the variable is already set by another program, you can still apply double/single quotes with sed or similar tools.

Example:

 $ b="Just another text here"
 $ echo "$b"
 Just another text here
 $ sed 's/text/"'\0'"/' <<<"$b" #\0 is a special sed operator
 Just another "0" here #this is not what i wanted to be
 $ sed 's/text/\x22\x27\0\x27\x22/' <<<"$b"
 Just another "'text'" here #now we are talking. You would normally need a dozen of backslashes to achieve the same result in the normal way.

Moshe's solution is great but the problem may still exist if you need to put the list inside a div. (read: CSS counter-reset on nested list)

This style could prevent that issue:

ol > li {_x000D_
    counter-increment: item;_x000D_
}_x000D_
_x000D_
ol > li:first-child {_x000D_
  counter-reset: item;_x000D_
}_x000D_
_x000D_
ol ol > li {_x000D_
    display: block;_x000D_
}_x000D_
_x000D_
ol ol > li:before {_x000D_
    content: counters(item, ".") ". ";_x000D_
    margin-left: -20px;_x000D_
}

<ol>_x000D_
  <li>list not nested in div</li>_x000D_
</ol>_x000D_
_x000D_
<hr>_x000D_
_x000D_
<div>_x000D_
  <ol>_x000D_
  <li>nested in div</li>_x000D_
  <li>two_x000D_
    <ol>_x000D_
      <li>two.one</li>_x000D_
      <li>two.two</li>_x000D_
      <li>two.three</li>_x000D_
    </ol>_x000D_
  </li>_x000D_
  <li>three_x000D_
    <ol>_x000D_
      <li>three.one</li>_x000D_
      <li>three.two_x000D_
        <ol>_x000D_
          <li>three.two.one</li>_x000D_
          <li>three.two.two</li>_x000D_
        </ol>_x000D_
      </li>_x000D_
    </ol>_x000D_
  </li>_x000D_
  <li>four</li>_x000D_
  </ol>_x000D_
</div>

You can also set the counter-reset on li:before.

A more modern way to undo a merge is:

git merge --abort

And the slightly older way:

git reset --merge

The old-school way described in previous answers (warning: will discard all your local changes):

git reset --hard

But actually, it is worth noticing that git merge --abort is only equivalent to git reset --merge given that MERGE_HEAD is present. This can be read in the git help for merge command.

git merge --abort is equivalent to git reset --merge when MERGE_HEAD is present.

After a failed merge, when there is no MERGE_HEAD, the failed merge can be undone with git reset --merge but not necessarily with git merge --abort, so they are not only old and new syntax for the same thing. This is why i find git reset --merge to be much more useful in everyday work.

For instance you can use

update tablename set datetimefield='19980223 14:23:05'
update tablename set datetimefield='02/23/1998 14:23:05'
update tablename set datetimefield='1998-12-23 14:23:05'
update tablename set datetimefield='23 February 1998 14:23:05'
update tablename set datetimefield='1998-02-23T14:23:05'

You need to be careful of day/month order since this will be language dependent when the year is not specified first. If you specify the year first then there is no problem; date order will always be year-month-day.

This is long one but a full proof solution, never fails

Just pass your number to this function as a double, it will return you rounding the decimal value up to the nearest value of 5;

if 4.25, Output 4.25

if 4.20, Output 4.20

if 4.24, Output 4.20

if 4.26, Output 4.30

if you want to round upto 2 decimal places,then use

DecimalFormat df = new DecimalFormat("#.##");
roundToMultipleOfFive(Double.valueOf(df.format(number)));

if up to 3 places, new DecimalFormat("#.###")

if up to n places, new DecimalFormat("#.nTimes #")

 public double roundToMultipleOfFive(double x)
            {

                x=input.nextDouble();
                String str=String.valueOf(x);
                int pos=0;
                for(int i=0;i<str.length();i++)
                {
                    if(str.charAt(i)=='.')
                    {
                        pos=i;
                        break;
                    }
                }

                int after=Integer.parseInt(str.substring(pos+1,str.length()));
                int Q=after/5;
                int R =after%5;

                if((Q%2)==0)
                {
                    after=after-R;
                }
                else
                {
                   if(5-R==5)
                   {
                     after=after;
                   }
                   else after=after+(5-R);
                }

                       return Double.parseDouble(str.substring(0,pos+1).concat(String.valueOf(after))));

            }

I faced the same problem while installing Eclipse for c/c++ applications .I downloaded Mingw GCC ,put its bin folder in your path ,used it in toolchains while making new C++ project in Eclipse and build which solved my problem. Referred to this video

The below code is to add 4 hours to date(example today's date)

var today = new Date();
today.setHours(today.getHours() + 4);

It will not cause error if you try to add 4 to 23 (see the docs):

If a parameter you specify is outside of the expected range, setHours() attempts to update the date information in the Date object accordingly

1) first remove cordova cmd

npm uninstall -g cordova

2) After that remove ionic

npm uninstall -g ionic

i've been researching for that too but unfortunately the facebook device auth is still on experimental and they didn't give new keys (partner) to use the device auth.

You can find the working example here: http://oauth-device-demo.appspot.com/ Just look at the website source and you can have the appID that works with it.

The other one is twitter PIN oauth it's working and publicly available (i'm using it) https://dev.twitter.com/docs/auth/pin-based-authorization

I fear i incur upset reactions but nevertheless, to clarify for me if i'm wrong or those seeing this question and being interested in an answer:

my understanding of https://tools.ietf.org/html/rfc1122 whose status is "an official specification" and as such is the reference for the terminology used in this question and which is neither superseded by another RFC nor has errata contradicting the following:

theoretically, ie. based on the written spec., UDP like given by https://tools.ietf.org/html/rfc1122#section-4 has no "packet size". Thus the answer could be "indefinite"

In practice, which is what this questions likely seeked (and which could be updated for current tech in action), this might be different and I don't know.

I apologize if i caused upsetting. https://tools.ietf.org/html/rfc1122#page-8 The "Internet Protocol Suite" and "Architectural Assumptions" don't make clear to me the "assumption" i was on, based on what I heard, that the layers are separate. Ie. the layer UDP is in does not have to concern itself with the layer IP is in (and the IP layer does have things like Reassembly, EMTU_R, Fragmentation and MMS_R (https://tools.ietf.org/html/rfc1122#page-56))

I think this is pretty obvious :

• $observe is used in linking function of directives.
• $watch is used on scope to watch any changing in its values.

Keep in mind : both the function has two arguments,

$observe/$watch(value : string, callback : function);

• value : is always a string reference to the watched element (the name of a scope's variable or the name of the directive's attribute to be watched)
• callback : the function to be executed of the form function (oldValue, newValue)

I have made a plunker, so you can actually get a grasp on both their utilization. I have used the Chameleon analogy as to make it easier to picture.

Same problem but @Angelo answer didn't work for me, because I'm using same server with different credentials. I used the approach below and tested it on Windows 10.

cmdkey /add:server01 /user:<username> /pass:<password>

Then used mstsc /v:server01 to connect to the server.

The point is to use names instead of ip addresses to avoid conflict between credentials. If you don't have a DNS server locally accessible try c:\windows\system32\drivers\etc\hosts file.

You can try DBVisualizer some features are not free, but you can get an evaluate license...

Nick answers its fine but you will have functions which repeats itsself while scrolling or will not work at all if user has the window zoomed. I came up with an easy fix just math.round the first height and it works just as assumed.

    if (Math.round($(window).scrollTop()) + $(window).innerHeight() == $(document).height()){
    loadPagination();
    $(".go-up").css("display","block").show("slow");
}

If you do want to use null values with '=' or '<>' operators you may find the

answer from @egallardo hier

very useful.

Short example for '=': The expression

WHERE t.field = :param

you refactor like this

WHERE ((:param is null and t.field is null) or t.field = :param)

Now you can set the parameter param either to some non-null value or to null:

query.setParameter("param", "Hello World"); // Works
query.setParameter("param", null);          // Works also

I have used jQuery AJAX to make AJAX requests.

Check the following code:

<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $('#call').click(function ()
            {
                $.ajax({
                    type: "post",
                    url: "testme", //this is my servlet
                    data: "input=" +$('#ip').val()+"&output="+$('#op').val(),
                    success: function(msg){      
                            $('#output').append(msg);
                    }
                });
            });

        });
    </script>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
</head>
<body>
    input:<input id="ip" type="text" name="" value="" /><br></br>
    output:<input id="op" type="text" name="" value="" /><br></br>
    <input type="button" value="Call Servlet" name="Call Servlet" id="call"/>
    <div id="output"></div>
</body>

There is no built-in extension method to do this. Although defining one is fairly straight forward. At the bottom of the post is a method I defined called Iterate. It can be used like so

collection.Iterate(c => { c.PropertyToSet = value;} );

Iterate Source

public static void Iterate<T>(this IEnumerable<T> enumerable, Action<T> callback)
{
    if (enumerable == null)
    {
        throw new ArgumentNullException("enumerable");
    }

    IterateHelper(enumerable, (x, i) => callback(x));
}

public static void Iterate<T>(this IEnumerable<T> enumerable, Action<T,int> callback)
{
    if (enumerable == null)
    {
        throw new ArgumentNullException("enumerable");
    }

    IterateHelper(enumerable, callback);
}

private static void IterateHelper<T>(this IEnumerable<T> enumerable, Action<T,int> callback)
{
    int count = 0;
    foreach (var cur in enumerable)
    {
        callback(cur, count);
        count++;
    }
}

install

$ sudo rabbitmq-plugins enable rabbitmq_management

and go to http://localhost:15672/#/queues if you are using localhost. the default password will be username: guest, password: guest and go to queues tab and delete the queue.

The error is because fName is included in the SELECT list, but is not included in a GROUP BY clause and is not part of an aggregate function (Count(), Min(), Max(), Sum(), etc.)

You can fix that problem by including fName in a GROUP BY. But then you will face the same issue with surname. So put both in the GROUP BY:

SELECT
    fName,
    surname,
    Count(*) AS num_rows
FROM
    author
    INNER JOIN book
    ON author.aID = book.authorID;
GROUP BY
    fName,
    surname

Note I used Count(*) where you wanted SUM(orders.quantity). However, orders isn't included in the FROM section of your query, so you must include it before you can Sum() one of its fields.

If you have Access available, build the query in the query designer. It can help you understand what features are possible and apply the correct Access SQL syntax.

Here is a very easy way of doing that

 $(function () {
    $(".glyphicon").unbind('click');
    $(".glyphicon").click(function (e) {
        $(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");
});

Hope this helps :D

In your php.ini configuration file simply uncomment the extension:

;extension=pdo_mysql

(You can find your php.ini file in the php folder where your server is installed.)

make this to

extension=pdo_mysql

now you need to configure your .env file in find DB_DATABASE= write in that database name which you used than migrate like if i used my database and database name is "abc" than i need to write there DB_DATABASE=abc and save that .env file and run command again

php artisan migrate

so after run than you got some msg like as:

php artisan migrate
Migration table created successfully.

Filter array of objects, which property matches value, returns array:

var result = jsObjects.filter(obj => {
  return obj.b === 6
})

See the MDN Docs on Array.prototype.filter()

const jsObjects = [_x000D_
  {a: 1, b: 2}, _x000D_
  {a: 3, b: 4}, _x000D_
  {a: 5, b: 6}, _x000D_
  {a: 7, b: 8}_x000D_
]_x000D_
_x000D_
let result = jsObjects.filter(obj => {_x000D_
  return obj.b === 6_x000D_
})_x000D_
_x000D_
console.log(result)

Find the value of the first element/object in the array, otherwise undefined is returned.

var result = jsObjects.find(obj => {
  return obj.b === 6
})

See the MDN Docs on Array.prototype.find()

const jsObjects = [_x000D_
  {a: 1, b: 2}, _x000D_
  {a: 3, b: 4}, _x000D_
  {a: 5, b: 6}, _x000D_
  {a: 7, b: 8}_x000D_
]_x000D_
_x000D_
let result = jsObjects.find(obj => {_x000D_
  return obj.b === 6_x000D_
})_x000D_
_x000D_
console.log(result)

Note that if there are ties in top 10 values, you will only get the top 10 rows, not the top 10 values with the answers provided. Ex: if the top 5 values are 10, 11, 12, 13, 14, 15 but your data contains 10, 10, 11, 12, 13, 14, 15 you will only get 10, 10, 11, 12, 13, 14 as your top 5 with a LIMIT

Here is a solution which will return more than 10 rows if there are ties but you will get all the rows where some_value_column is technically in the top 10.

select
  *
from
  (select
     *,
     rank() over (order by some_value_column desc) as my_rank
  from mytable) subquery
where my_rank <= 10

The <footer> tag seems like a good candidate:

<footer>&copy; 2011 Some copyright message</footer>

Try this.

To get the data from the UserDefaults.

var defaults = NSUserDefaults.standardUserDefaults()
var dict : NSDictionary = ["key":"value"]
var array1: NSArray = dict.allValues // Create a dictionary and assign that to this array
defaults.setObject(array1, forkey : "MyKey")

var myarray : NSArray = defaults.objectForKey("MyKey") as NSArray
println(myarray)

Educated guess: You have a ISO-8859-1 encoded pound sign in a UTF-8 encoded page.

Make sure your data is in the right encoding and everything will work fine.

Only thing that comes even close is the :contains pseudo class in CSS3, but that only selects textual content, not tags or elements, so you're out of luck.

A simpler way to select a parent with specific children in jQuery can be written as (with :has()):

$('#parent:has(#child)');
