Programs & Examples On #Enscript

I was facing the same issue while i was using JDK 1.8.0_05 64 bit and eclipse-jee-oxygen-3a-win32-x86_64 on Windows 64 bit Operating System.

Finally i resolved the issue by changing JDK version jdk1.8.0_05 to jdk1.8.0_172

Here is an example of using super():

#New-style classes inherit from object, or from another new-style class
class Dog(object):

    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self):
        self.moves.append('walk')
        self.moves.append('run')

    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super(Superdog, self).moves_setup()
        self.moves.append('fly')

dog = Superdog('Freddy')
print dog.name # Freddy
dog.moves_setup()
print dog.get_moves() # ['walk', 'run', 'fly']. 
#As you can see our Superdog has all moves defined in the base Dog class

the easiest way of doing this is

$("#tabs div[aria-hidden='false']");

and for index

$("#tabs div[aria-hidden='false']").index();

Consider the case in which a service worker acts as an agnostic cache. Your only goal is serve the same resources that you would get from the network, but faster. Of course you can't ensure all the resources will be part of your origin (consider libraries served from CDNs, for instance). As the service worker has the potential of altering network responses, you need to guarantee you are not interested in the contents of the response, nor on its headers, nor even on the result. You're only interested on the response as a black box to possibly cache it and serve it faster.

This is what { mode: 'no-cors' } was made for.

Even better, try an OrderedDict (assuming you want something like a list). Closer to a list than a regular dict since the keys have an order just like list elements have an order. With a regular dict, the keys have an arbitrary order.

Note that this is available in Python 3 and 2.7. If you want to use with an earlier version of Python you can find installable modules to do that.

the point can be if you are not using valid login for linked server. Problem is on destination server side.

There are few steps to try:

1. Align db user and login on destination server: alter user [DBUSER_of_linkedserverlogin] with login = [linkedserverlogin]

2. recreate login on destination server used by linked server.

3. Backup table and recreate it.

2nd resolved my issue with "The value violated the integrity constraints for the column.".

Since your question is more generic so try to implement it with XML Parsers available in Java .If you need it in specific to parsers, update your code here what you have tried yet

<?xml version="1.0" encoding="UTF-8"?>
<ep>
    <source type="xml">TEST</source>
    <source type="text"></source>
</ep>

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse("uri to xmlfile");
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile("//ep/source[@type]");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);

for (int i = 0; i < nl.getLength(); i++)
{
    Node currentItem = nl.item(i);
    String key = currentItem.getAttributes().getNamedItem("type").getNodeValue();
    System.out.println(key);
}

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;

SELECT TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') FROM EmpTable;

An SQLfiddle to test with.

MYPORT=8888; 
kill -9 `ps -ef |grep SimpleHTTPServer |grep $MYPORT |awk '{print $2}'`

That is it!

Explain command line :

• ps -ef : list all process.

• grep SimpleHTTPServer : filter process which belong to "SimpleHTTPServer"

• grep $MYPORT : filter again process belong to "SimpleHTTPServer" where port is MYPORT (.i.e: MYPORT=8888)

• awk '{print $2}' : print second column of result which is the PID (Process ID)

• kill -9 <PID> : Force Kill process with the appropriate PID.

You can import the whole module as follows:

import * as FriendCard from './../pages/FriendCard';

For more details please refer the modules section of Typescript official docs.

• System.Environment.MachineName from a console or WinForms app.
• HttpContext.Current.Server.MachineName from a web app
• System.Net.Dns.GetHostName() to get the FQDN

See How to find FQDN of local machine in C#/.NET ? if the last doesn't give you the FQDN and you need it.

See details about Difference between SystemInformation.ComputerName, Environment.MachineName, and Net.Dns.GetHostName

#!/bin/bash
message="some text"
message="$message add some more"

echo $message

some text add some more

This is called an initialization list. It is for passing arguments to the constructor of a parent class. Here is a good link explaining it: Initialization Lists in C++

for a 2-D tensor, you can get the number of rows and columns as int32 using the following code:

rows, columns = map(lambda i: i.value, tensor.get_shape())

I also just changed the "Start in" setting of the shortcut icon to: %HOMEDRIVE%/xampp/htdocs/

You can edit it. The content of the file is literally "Deny from all" which is an Apache directive: http://httpd.apache.org/docs/2.2/mod/mod_authz_host.html#deny

Since Server.MapPath() does not exist within a Web Api (Soap or REST), you'll need to denote the local- relative to the web server's context- home directory. The easiest way to do so is with:

string AppContext.BaseDirectory { get;}

You can then use this to concatenate a path string to map the relative path to any file.
NOTE: string paths are \ and not / like they are in mvc.

Ex:

System.IO.File.Exists($"{**AppContext.BaseDirectory**}\\\\Content\\\\pics\\\\{filename}");

returns true- positing that this is a sound path in your example

Scope Identity: Identity of last record added within the stored procedure being executed.

@@Identity: Identity of last record added within the query batch, or as a result of the query e.g. a procedure that performs an insert, the then fires a trigger that then inserts a record will return the identity of the inserted record from the trigger.

IdentCurrent: The last identity allocated for the table.

In browsers other than Internet Explorer, you can pass parameters to the function together after the delay:

var timeoutID = window.setTimeout(func, delay, [param1, param2, ...]);

So, you can do this:

var timeoutID = window.setTimeout(function (self) {
  console.log(self); 
}, 500, this);

This is better in terms of performance than a scope lookup (caching this into a variable outside of the timeout / interval expression), and then creating a closure (by using $.proxy or Function.prototype.bind).

The code to make it work in IEs from Webreflection:

/*@cc_on
(function (modifierFn) {
  // you have to invoke it as `window`'s property so, `window.setTimeout`
  window.setTimeout = modifierFn(window.setTimeout);
  window.setInterval = modifierFn(window.setInterval);
})(function (originalTimerFn) {
    return function (callback, timeout){
      var args = [].slice.call(arguments, 2);
      return originalTimerFn(function () { 
        callback.apply(this, args) 
      }, timeout);
    }
});
@*/

You might want to have a look at some of the template frameworks that are available at the moment. Some of them are spin offs as a result of MVC but that isn't required. Spark is a good one.

Just add AsEnumerable() andToList() , so it looks like this

db.Favorites
    .Where(x => x.userId == userId)
    .Join(db.Person, x => x.personId, y => y.personId, (x, y).ToList().AsEnumerable()

ToList().AsEnumerable()

<div id="AlertDiv" style="width:600px;height:400px;border:SOLID 1px;">
    <h1 style="width:100%;height:10%;text-align:center;position:relative;top:40%;">Yes</h1>
</div>

Node v0.6.x has a stable zlib module in core now - there are some examples on how to use it server-side in the docs too.

An example (taken from the docs):

// server example
// Running a gzip operation on every request is quite expensive.
// It would be much more efficient to cache the compressed buffer.
var zlib = require('zlib');
var http = require('http');
var fs = require('fs');
http.createServer(function(request, response) {
  var raw = fs.createReadStream('index.html');
  var acceptEncoding = request.headers['accept-encoding'];
  if (!acceptEncoding) {
    acceptEncoding = '';
  }

  // Note: this is not a conformant accept-encoding parser.
  // See http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.3
  if (acceptEncoding.match(/\bdeflate\b/)) {
    response.writeHead(200, { 'content-encoding': 'deflate' });
    raw.pipe(zlib.createDeflate()).pipe(response);
  } else if (acceptEncoding.match(/\bgzip\b/)) {
    response.writeHead(200, { 'content-encoding': 'gzip' });
    raw.pipe(zlib.createGzip()).pipe(response);
  } else {
    response.writeHead(200, {});
    raw.pipe(response);
  }
}).listen(1337);

If you install using bundler as suggested by gryzzly and the gem creates a binary then make sure you run it with bundle exec mygembinary as the gem is stored in a bundler directory which is not visible on the normal gem path.

You can, but the variable in your last include will overwrite the variable in your first one:

myfile.php

$var = 'test';

mysecondfile.php

$var = 'tester';

test.php

include 'myfile.php';
echo $var;

include 'mysecondfile.php';
echo $var;

Output:

test

tester

I suggest using different variable names.

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

You can do the following in EcmaScript2016

Correction: it's a stage 3 proposal, still it has always worked for me

const objA = {
  attrA: 'hello',
  attrB: true
}

const objB = {
  attrC: 2
}

const mergedObj = {...objA, ...objB}

Apparently things are changing.... getDerivedStateFromProps() is now the preferred function.

class Component extends React.Component {_x000D_
  static getDerivedStateFromProps(props, current_state) {_x000D_
    if (current_state.value !== props.value) {_x000D_
      return {_x000D_
        value: props.value,_x000D_
        computed_prop: heavy_computation(props.value)_x000D_
      }_x000D_
    }_x000D_
    return null_x000D_
  }_x000D_
}

Your project should almost always use the past tense. In any case, the project should always use the same tense for consistency and clarity.

I understand some of the other arguments arguing to use the present tense, but they usually don't apply. The following bullet points are common arguments for writing in the present tense, and my response.

• Writing in the present tense tells someone what applying the commit will do, rather than what you did.

This is the most correct reason one would want to use the present tense, but only with the right style of project. This manner of thinking considers all commits as optional improvements or features, and you are free to decide which commits to keep and which to reject in your particular repository.

This argument works if you are dealing with a truly distributed project. If you are dealing with a distributed project, you are probably working on an open source project. And it is probably a very large project if it is really distributed. In fact, it's probably either the Linux kernel or Git. Since Linux is likely what caused Git to spread and gain in popularity, it's easy to understand why people would consider its style the authority. Yes, the style makes sense with those two projects. Or, in general, it works with large, open source, distributed projects.

That being said, most projects in source control do not work like this. It is usually incorrect for most repositories. It's a modern way of thinking about a commits: Subversion (SVN) and CVS repositories could barely support this style of repository check-ins. Usually an integration branch handled filtering bad check-ins, but those generally weren't considered "optional" or "nice-to-have features".

In most scenarios, when you are making commits to a source repository, you are writing a journal entry which describes what changed with this update, to make it easier for others in the future to understand why a change was made. It generally isn't an optional change - other people in the project are required to either merge or rebase on it. You don't write a diary entry such as "Dear diary, today I meet a boy and he says hello to me.", but instead you write "I met a boy and he said hello to me."

Finally, for such non-distributed projects, 99.99% of the time a person will be reading a commit message is for reading history - history is read in the past tense. 0.01% of the time it will be deciding whether or not they should apply this commit or integrate it into their branch/repository.

• Consistency. That's how it is in many projects (including git itself). Also git tools that generate commits (like git merge or git revert) do it.

No, I guarantee you that the majority of projects ever logged in a version control system have had their history in the past tense (I don't have references, but it's probably right, considering the present tense argument is new since Git). "Revision" messages or commit messages in the present tense only started making sense in truly distributed projects - see the first point above.

• People not only read history to know "what happened to this codebase", but also to answer questions like "what happens when I cherry-pick this commit", or "what kind of new things will happen to my code base because of these commits I may or may not merge in the future".

See the first point. 99.99% of the time a person will be reading a commit message is for reading history - history is read in the past tense. 0.01% of the time it will be deciding whether or not they should apply this commit or integrate it into their branch/repository. 99.99% beats 0.01%.

• It's usually shorter

I've never seen a good argument that says use improper tense/grammar because it's shorter. You'll probably only save 3 characters on average for a standard 50 character message. That being said, the present tense on average will probably be a few characters shorter.

• You can name commits more consistently with titles of tickets in your issue/feature tracker (which don't use past tense, although sometimes future)

Tickets are written as either something that is currently happening (e.g. the app is showing the wrong behavior when I click this button), or something that needs to be done in the future (e.g. the text will need a review by the editor).

History (i.e. commit messages) is written as something that was done in the past (e.g. the problem was fixed).

Just adding to Jason's answer, the . selector is only for classes. If you want to select something other than the element, id, or class, you need to wrap it in square brackets.

e.g.

$('element[attr=val]')

Thumbs up first before use codes please!!! Create an image that fully cover the whole tab bar item for each item. This is needed to use the image you created as a tab bar item button. Be sure to make the height/width ratio be the same of each tab bar item too. Then:

UITabBarController *tabBarController = (UITabBarController *)self;
UITabBar *tabBar = tabBarController.tabBar;
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];
UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];

int x,y;

x = tabBar.frame.size.width/4 + 4; //when doing division, it may be rounded so that you need to add 1 to each item; 
y = tabBar.frame.size.height + 10; //the height return always shorter, this is compensated by added by 10; you can change the value if u like.

//because the whole tab bar item will be replaced by an image, u dont need title
tabBarItem1.title = @"";
tabBarItem2.title = @"";
tabBarItem3.title = @"";
tabBarItem4.title = @"";

[tabBarItem1 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"item1-select.png"] scaledToSize:CGSizeMake(x, y)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"item1-deselect.png"] scaledToSize:CGSizeMake(x, y)]];//do the same thing for the other 3 bar item

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

I found the answer. IE stores passwords in two different locations based on the password type:

• Http-Auth: %APPDATA%\Microsoft\Credentials, in encrypted files
• Form-based: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2, encrypted with the url

From a very good page on NirSoft.com:

Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:

• AutoComplete Passwords: These passwords are saved in the following location in the Registry: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2 The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).

• HTTP Authentication Passwords: These passwords are stored in the Credentials file under Documents and Settings\Application Data\Microsoft\Credentials, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.

In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead/CredWrite, where the user can manage their passwords from within an established UI system in Windows.

When do you choose functional programming over object oriented?

When you anticipate a different kind of software evolution:

• Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

• Functional languages are good when you have a fixed set of things, and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types, and the existing functions are left alone.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method.

• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This problem has been well known for many years; in 1998, Phil Wadler dubbed it the "expression problem". Although some researchers think that the expression problem can be addressed with such language features as mixins, a widely accepted solution has yet to hit the mainstream.

What are the typical problem definitions where functional programming is a better choice?

Functional languages excel at manipulating symbolic data in tree form. A favorite example is compilers, where source and intermediate languages change seldom (mostly the same things), but compiler writers are always adding new translations and code improvements or optimizations (new operations on things). Compilation and translation more generally are "killer apps" for functional languages.

The error shows you either didn't create the rails project yet or you're not in the rails project directory.

Suppose if you're working on myapp project. You've to move to that project directory on your command line and then generate the model. Here are some steps you can refer.

Example: Assuming you didn't create the Rails app yet:

$> rails new myapp
$> cd myapp

Now generate the model from your commandline.

$> rails generate model your_model_name 

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

The below code will give you list of all the rows:-

df[df['C'] != 'XYZ']

To store the values from the above code into a dataframe :-

newdf = df[df['C'] != 'XYZ']

In the html file there are three input boxes with userid,username,department respectively.

These inputboxes are used to get the input from the user.

The user can add any number of inputs to the page.

When clicking the button the script will enable the debugger mode.

Along the lines of Tim Down's answer but leveraging jQuery (mentioned by the OP) and loosely coupling the containing page and the iframe, you could do the following:

In the iframe:

<script>
    $(function() {
        var w = window;
        if (w.frameElement != null
                && w.frameElement.nodeName === "IFRAME"
                && w.parent.jQuery) {
            w.parent.jQuery(w.parent.document).trigger('iframeready');
        }
    });
</script>

In the containing page:

<script>
    function myHandler() {
        alert('iframe (almost) loaded');
    }
    $(document).on('iframeready', myHandler);
</script>

The iframe fires an event on the (potentially existing) parent window's document - please beware that the parent document needs a jQuery instance of itself for this to work. Then, in the parent window you attach a handler to react to that event.

This solution has the advantage of not breaking when the containing page does not contain the expected load handler. More generally speaking, it shouldn't be the concern of the iframe to know its surrounding environment.

Please note, that we're leveraging the DOM ready event to fire the event - which should be suitable for most use cases. If it's not, simply attach the event trigger line to the window's load event like so:

$(window).on('load', function() { ... });

xampp port 80 is busy when some other application is using the same port at that time. This can be solved by using one of the following methods:

1. Detect the application which is using the port 80 and close it.
2. This one is more efficient. xampp installs apache server with default port 80. So, you can change this port manually to any number.

Just find the httpd.conf file in xampp installation and replace the following line of code.

#Listen 12.34.56.78:1234
Listen 80

to any port number of your choice. Here, i have taken 8000.

#Listen 12.34.56.78:1234
Listen 8000

Find the following code in the same file httpd.conf

ServerName localhost

Replace with the following, take the same number you have used in upper code.

ServerName localhost:8000

The crux of the solution is setting

CURLOPT_RETURNTRANSFER => true

then

$response = curl_exec($ch);

CURLOPT_RETURNTRANSFER tells PHP to store the response in a variable instead of printing it to the page, so $response will contain your response. Here's your most basic working code (I think, didn't test it):

// init curl object        
$ch = curl_init();

// define options
$optArray = array(
    CURLOPT_URL => 'http://www.google.com',
    CURLOPT_RETURNTRANSFER => true
);

// apply those options
curl_setopt_array($ch, $optArray);

// execute request and get response
$result = curl_exec($ch);

I am using this Typescript snippet:

function UInt8ArrayToString(uInt8Array: Uint8Array): string
{
    var s: string = "[";
    for(var i: number = 0; i < uInt8Array.byteLength; i++)
    {
        if( i > 0 )
            s += ", ";
        s += uInt8Array[i];
    }
    s += "]";
    return s;
}

Remove the type annotations if you need the JavaScript version. Hope this helps!

You could also give them all the same name so they are an array, but give them different values:

<div id="checkboxes">
    <input type="checkbox" name="c_n[]" value="c_n_0" checked="checked" />Option 1
    <input type="checkbox" name="c_n[]" value="c_n_1" />Option 2
    <input type="checkbox" name="c_n[]" value="c_n_2" />Option 3
    <input type="checkbox" name="c_n[]" value="c_n_3" checked="checked" />Option 4
</div>

You can then get only the value of only the ticked ones using map:

$('#checkboxes input:checked[name="c_n[]"]')
            .map(function () { return $(this).val(); }).get()

setTimeout is not an async function, so you can't use it with ES7 async-await. But you could implement your sleep function using ES6 Promise:

function sleep (fn, par) {
  return new Promise((resolve) => {
    // wait 3s before calling fn(par)
    setTimeout(() => resolve(fn(par)), 3000)
  })
}

Then you'll be able to use this new sleep function with ES7 async-await:

var fileList = await sleep(listFiles, nextPageToken)

Please, note that I'm only answering your question about combining ES7 async/await with setTimeout, though it may not help solve your problem with sending too many requests per second.

Update: Modern node.js versions has a buid-in async timeout implementation, accessible via util.promisify helper:

const {promisify} = require('util');
const setTimeoutAsync = promisify(setTimeout);

Another nice approach can be seen here: http://blogs.microsoft.co.il/blogs/eladkatz/archive/2011/05/29/what-is-the-easiest-way-to-set-spacing-between-items-in-stackpanel.aspx Link is broken -> this is webarchive of this link.

It shows how to create an attached behavior, so that syntax like this would work:

<StackPanel local:MarginSetter.Margin="5">
   <TextBox Text="hello" />
   <Button Content="hello" />
   <Button Content="hello" />
</StackPanel>

This is the easiest & fastest way to set Margin to several children of a panel, even if they are not of the same type. (I.e. Buttons, TextBoxes, ComboBoxes, etc.)

Multitiple inheritance is not possible in C#, however it can be simulated using interfaces, see Simulated Multiple Inheritance Pattern for C#.

The basic idea is to define an interface for the members on class B that you wish to access (call it IB), and then have C inherit from A and implement IB by internally storing an instance of B, for example:

class C : A, IB
{
    private B _b = new B();

    // IB members
    public void SomeMethod()
    {
        _b.SomeMethod();
    }
}

The answers to this question are a little out of date and missing potentially key steps, so this is an updated guide for installing an app from an external developer.

----- How to Resign an iOS App -----

Let's say you receive an app (e.g. MyApp.ipa) from another developer, and you want to be able to install and run it on your devices (by using ideviceinstaller, for example).

Prepare New Signing Assets

The first step is to attain a Provisioning Profile which includes all of the devices you wish to install and run on. Ensure that the profile contains a certificate that you have installed in your Keychain Access (e.g. iPhone Developer: Some Body (XXXXXXXXXX) ). Download the profile (MyProfile.mobileprovision) so you can replace the profile embedded in the app.

Next, we are going to prepare an entitlements file to include in the signing. Open up your terminal and run the following.

$ security cms -D -i path/to/MyProfile.mobileprovision > provision.plist

This will create an xml file describing your Provisioning Profile. Next, we want to extract the entitlements into a file.

$ /usr/libexec/PlistBuddy -x -c 'Print :Entitlements' provision.plist > entitlements.plist

Replace The Provisioning Profile and Resign App

If you are working with a .ipa file, first, unzip the app (if you have a .app instead, you can skip this step).

$ unzip MyApp.ipa

Your working directory will now contain Payload/ and Payload/MyApp.app/. Next, remove the old code signature files.

$ rm -rf Payload/MyApp.app/_CodeSignature

Replace the existing provisioning profile (i.e. embedded.mobileprovision) with your own.

$ cp path/to/MyProfile.mobileprovision Payload/MyApp.app/embedded.mobileprovision

Now sign the app with the certificate included in your provisioning profile and the entitlements.plist that you created earlier.

$ /usr/bin/codesign -f -s "iPhone Developer: Some Body (XXXXXXXXXX)" --entitlements entitlements.plist Payload/MyApp.app

IMPORTANT: You must also resign all frameworks included in the app. You will find these in Payload/MyApp.app/Frameworks. If the app is written in Swift or if it includes any additional frameworks these must be resigned or the app will install but not run.

$ /usr/bin/codesign -f -s "iPhone Developer: Some Body (XXXXXXXXXX)" --entitlements entitlements.plist Payload/MyApp.app/Frameworks/*

You can now rezip the app.

$ zip -qr MyApp-resigned.ipa Payload

Done

You may now remove the Payload directory since you have your original app (MyApp.ipa) and your resigned version (MyApp-resigned.ipa). You can now install MyApp-resigned.ipa on any device included in your provisioning profile.

Edit your php.ini file, search for soap.wsdl_cache_enabled and set the value to 0

[soap]
; Enables or disables WSDL caching feature.
; http://php.net/soap.wsdl-cache-enabled
soap.wsdl_cache_enabled=0

I just cut-and-pasted your example into a file; it ran fine under bash. I don't see any problems with it.

For good measure you may want to ensure it ends with a newline, though bash shouldn't care. (It runs for me both with and without the final newline.)

You'll sometimes see strange errors if you've accidentally embedded a control character in the file. Since it's a short script, try creating a new script by pasting it from your question here on StackOverflow, or by simply re-typing it.

What version of bash are you using? (bash --version)

Good luck!

For saving the graph:

matplotlib.rcParams['savefig.dpi'] = 300

This answer will be for swift dictionary w/ String keys. Like this one below.

let dict: [String: Int] = ["hey": 1, "yo": 2, "sup": 3, "hello": 4, "whassup": 5]

Here's the extension I'll use.

extension Dictionary {
  func allKeys() -> [String] {
    guard self.keys.first is String else {
      debugPrint("This function will not return other hashable types. (Only strings)")
      return []
    }
    return self.flatMap { (anEntry) -> String? in
                          guard let temp = anEntry.key as? String else { return nil }
                          return temp }
  }
}

And I'll get all the keys later using this.

let componentsArray = dict.allKeys()

Worth a read: http://bigdingus.com/2007/12/29/html-escaping-in-javascript/

escapeHTML: (function() {
 var MAP = {
   '&': '&',
   '<': '&lt;',
   '>': '&gt;',
   '"': '&#34;',
   "'": '&#39;'
 };
  var repl = function(c) { return MAP[c]; };
  return function(s) {
    return s.replace(/[&<>'"]/g, repl);
  };
})()

Note: Only run this once. And don't run it on already encoded strings e.g. & becomes &

The way it worked for me in order to replace the old name of my project for a new one (everywhere in my codebase) is the following:

1. Close Android Studio.
2. Rename the root folder of your project.
3. Open Android Studio. It will not find the old project, so you must import it again. This step will generate the configuration again (no need to touch your .idea files manually), including a new .iml file with the new project name. Afterwards you can delete the old .iml file if you want.
4. Once the renamed project is imported in Android Studio you need to rename your source packages to use the new project name in case you used the old project name as part of the package path.

NOTE: This worked for Android Studio 2.1.2

I 've tried a lot of examples but with Django mutagen plays nicely.

Example checking if files is mp3

from mutagen.mp3 import MP3, HeaderNotFoundError  

try:
    audio = MP3(file)
except HeaderNotFoundError:
    raise ValidationError('This file should be mp3')

The downside is that your ability to check file types is limited, but it's a great way if you want not only check for file type but also to access additional information.

If you use Material Design in your app then use this

<com.google.android.material.card.MaterialCardView
            android:layout_width="75dp"
            android:layout_height="75dp"
            app:cardCornerRadius="50dp"
            app:strokeWidth="1dp"
            app:strokeColor="@color/black">
            <ImageView
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:id="@+id/circular_image"
                android:scaleType="fitCenter"
                android:src="@drawable/your_img" />
        </com.google.android.material.card.MaterialCardView>

The solution with copying 32-bit libs over to 64-bit did not work for me. What worked was unchecking Target Platform Prefer 32-bit check mark in project properties.

Here is one for DOS or Unix new line:

    void chomp( string &s)
    {
            int pos;
            if((pos=s.find('\n')) != string::npos)
                    s.erase(pos);
    }

I tested what @Samy Dindane suggested in the comment on the OP.

I believe it works, try

git fetch <remote_name> <remote_branch>:<local_branch>
git checkout <local_branch>

Here's an example for a fictitious remote repository named foo with a branch named bar where I create a local branch bar tracking the remote:

git fetch foo bar:bar
git checkout bar

Posting this answer for folks wanting to initialize list with POCOs and also coz this is the first thing that pops up in search but all answers only for list of type string.

You can do this two ways one is directly setting the property by setter assignment or much cleaner by creating a constructor that takes in params and sets the properties.

class MObject {        
        public int Code { get; set; }
        public string Org { get; set; }
    }

List<MObject> theList = new List<MObject> { new MObject{ PASCode = 111, Org="Oracle" }, new MObject{ PASCode = 444, Org="MS"} };

OR by parameterized constructor

class MObject {
        public MObject(int code, string org)
        {
            Code = code;
            Org = org;
        }

        public int Code { get; set; }
        public string Org { get; set; }
    }

List<MObject> theList = new List<MObject> {new MObject( 111, "Oracle" ), new MObject(222,"SAP")};


        

This works a treat for both iOS6 and 7

Xamarin(C#) options

var buttonStyleItems = UIBarButtonItem.AppearanceWhenContainedIn(typeof(SettingsNavigationController));
buttonStyleItems.SetBackButtonTitlePositionAdjustment(new UIOffset(-1000, -1000), UIBarMetrics.Default);

Objective-C option

[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-1000, -1000) forBarMetrics:UIBarMetricsDefault];

I could remove the error (Run-time error '1004'. Application-defined or operation-defined error) by defining the counters as Single

You can get the "Forbidden" error if your user account lacks access permissions to a repository or repository path; it makes sense to check authorization settings for your user account. Make sure your system administrator hasn't provided you with No Access permission to the repository path.

If you are sure that permissions are set correctly, then double-check the URL you use. URLs in Apache Subversion are case-sensitive.

Additionally, I advise you to read articles on authorization in Subversion and VisualSVN Server:

• SVNBook about path-based authorization.
• VisualSVN Team's article about path-based authorization. It explains the principles of SVN authorization by comparing it with Windows Access Control.

The swift 4.2 version of solution would be the following:

let spacing: CGFloat = 10 // the amount of spacing to appear between image and title
self.button?.imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: spacing)
self.button?.titleEdgeInsets = UIEdgeInsets(top: 0, left: spacing, bottom: 0, right: 0)

This is fixed in later versions of PHPMyAdmin. The Ubuntu Software Repositories for Ubuntu 18.04.2 holds version 4.6.6.5, while they're currently at 4.9.0.1. Updating your PHPMyAdmin installation will fix this problem, but might prove to be riskier than just editing that one line of code. Here's how I did it on my Ubuntu Server. Steps are essentially the same (with a different path) for all operating systems.

1. Download PHPMyAdmin.

wget https://files.phpmyadmin.net/phpMyAdmin/4.9.0.1/phpMyAdmin-4.9.0.1-all-languages.zip
unzip phpMyAdmin-4.9.0.1-all-languages.zip

2. Backup your old PHPMyAdmin installation.

cp -r /usr/share/phpmyadmin ~/phpmyadmin-backup

3. Drop your new PHPMyAdmin on your old PHPMyAdmin

cd phpMyAdmin-4.9.0.1-all-languages
rm -r /usr/share/phpmyadmin/doc/html
cp -R * /usr/share/phpmyadmin/

Verify that it works. If it doesn't, welll... You have a backup, so restore it and manually edit the faulty line. In my own personal experience, I discovered after doing this that version 4.6.6.5 was not only riddled with bugs, but also incredibly slow compared to the new 4.9.0.1. The speed increase was pure magic for something I though was of "WordPress" quality.

Adding to the above answer, whoever looks for a solution, you can also try 'match' operator instead of 'like'. Do not want to be biased but it perfectly worked for me in Postgresql.

Note.query.filter(Note.message.match("%somestr%")).all()

It inherits database functions such as CONTAINS and MATCH. However, it is not available in SQLite.

For more info go Common Filter Operators

Yet another variant:

Date.prototype.isPrototypeOf(myDateObject)

If you want to remove specific punctuation from a string, it will probably be best to explicitly remove exactly what you want like

replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"")

Doing the above still doesn't return the string as you have specified it. If you want to remove any extra spaces that were left over from removing crazy punctuation, then you are going to want to do something like

replace(/\s{2,}/g," ");

My full example:

var s = "This., -/ is #! an $ % ^ & * example ;: {} of a = -_ string with `~)() punctuation";
var punctuationless = s.replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"");
var finalString = punctuationless.replace(/\s{2,}/g," ");

Results of running code in firebug console:

If you want to make a list with unique values from an existing list you can use

List myUniqueList = myList.stream().distinct().collect(Collectors.toList());

I'd give all the responses here a try first. But I wanted to just throw in what I do, just in case these do not work for you.

I've tried to solve the same problem you're having before, and in the end, what I decided on doing is to have only one JRE installed on my system at a given time. I do have about 10 different JDKs (1.3 through 1.6, and from various vendors - Sun, Oracle, IBM), since I do need it for development, but only one standalone JRE.

This has worked for me on my Windows 2000 + IE 6 computer at home, as well as my Windows XP + Multiple IE computer at work.

Only using class names is not sufficient in your case.

• By.cssSelector(".ban") has 15 matching nodes
• By.cssSelector(".hot") has 11 matching nodes
• By.cssSelector(".ban.hot") has 5 matching nodes

Therefore you need more restrictions to narrow it down. Option 1 and 2 below are available for css selector, 1 might be the one that suits your needs best.

Option 1: Using list items' index (CssSelector or XPath)

Limitations

• Not stable enough if site's structure changes

Example:

driver.FindElement(By.CssSelector("#rightbar > .menu > li:nth-of-type(3) > h5"));
driver.FindElement(By.XPath("//*[@id='rightbar']/ul/li[3]/h5"));

Option 2: Using Selenium's FindElements, then index them. (CssSelector or XPath)

Limitations

• Not stable enough if site's structure changes
• Not the native selector's way

Example:

// note that By.CssSelector(".ban.hot") and //*[contains(@class, 'ban hot')] are different, but doesn't matter in your case
IList<IWebElement> hotBanners = driver.FindElements(By.CssSelector(".ban.hot"));
IWebElement banUsStates = hotBanners[3];

Option 3: Using text (XPath only)

Limitations

• Not for multilanguage sites
• Only for XPath, not for Selenium's CssSelector

Example:

driver.FindElement(By.XPath("//h5[contains(@class, 'ban hot') and text() = 'us states']"));

Option 4: Index the grouped selector (XPath only)

Limitations

• Not stable enough if site's structure changes
• Only for XPath, not CssSelector

Example:

driver.FindElement(By.XPath("(//h5[contains(@class, 'ban hot')])[3]"));

Option 5: Find the hidden list items link by href, then traverse back to h5 (XPath only)

Limitations

• Only for XPath, not CssSelector
• Low performance
• Tricky XPath

Example:

driver.FindElement(By.XPath(".//li[.//ul/li/a[contains(@href, 'geo.craigslist.org/iso/us/al')]]/h5"));

Whilst agreeing with Douwe Maan and Erik's answers, there are a couple of other things here that you may find useful.

Firstly, within your head tags, you can reference a separate JavaScript file, which is then reusable:

<script language="JavaScript" src="/common/common.js"></script>

where common.js is your reusable function file in a top-level directory called common.

Secondly, you can delay the operation of a script using setTimeout, e.g.:

setTimeout(someFunction, 5000);

The second argument is in milliseconds. I mention this, because you appear to be trying to delay something in your original code snippet.

I had the same problem when I wrote two upstreams in NGINX conf

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
    server 127.0.0.1:9000;
}

...

fastcgi_pass php_upstream;

but in /etc/php/7.3/fpm/pool.d/www.conf I listened the socket only

listen = /var/run/php/my.site.sock

So I need just socket, no any 127.0.0.1:9000, and I just removed IP+port upstream

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
}

This could be rewritten without an upstream

fastcgi_pass unix:/var/run/php/my.site.sock;

You want to do:

git reset HEAD~

If you don't want the changes and blow everything away:

git reset --hard HEAD~

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

Solution (Updated: 24-may-2016): Change build.gradle (project)

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:X.X.X-lastVersionGradle'
    classpath 'com.google.gms:google-services:X.X.X-lastVersionGServices' // If use google-services

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

X.X.X-lastVersionGradle: For example: 2.1.0

X.X.X-lastVersionGServices: For example: 3.0.0 (support Firebase Analytics)

Note: if you're using the google-services plugin has to be the same version (if there)

Warning!! -> 2.2.0-alpha throws Unsupported major.minor version 52.0 if you don't use java JDK 8u91 and NetBeans 8.1

IN bootstrap 4 you need to add popper js for tooltip, I also don`t understand why bootstrap 4 includes external popper.js, It means bootstrap makes more complicated instead of easy when upgrading to the latest versions.

You can import popper js before bootstrap on angular or a simple html, Angular import would be like this

npm install popper.js --save

then go to .angular-cli.json and change the order like below.

 "scripts": [
        "../node_modules/jquery/dist/jquery.slim.min.js",
        "../node_modules/tether/dist/js/tether.min.js", 
        "../node_modules/popper.js/dist/umd/popper.js",              
        "../node_modules/bootstrap/dist/js/bootstrap.min.js"
      ],

you can also use CDN direct call popper js into your any project.

"".join([i for i in my_list])

This should work just like you asked!

Your web app can now take a 'native' screenshot of the client's entire desktop using getUserMedia():

Have a look at this example:

https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/

The client will have to be using chrome (for now) and will need to enable screen capture support under chrome://flags.

Nothing as useful as this: Common Data Structure Operations:

I found this to work flawlessly if you want to share whole screen.

@IBAction func shareButton(_ sender: Any) {

    let bounds = UIScreen.main.bounds
    UIGraphicsBeginImageContextWithOptions(bounds.size, true, 0.0)
    self.view.drawHierarchy(in: bounds, afterScreenUpdates: false)
    let img = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    let activityViewController = UIActivityViewController(activityItems: [img!], applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view
    self.present(activityViewController, animated: true, completion: nil)
}

In 3.0, there's now an easier way - hook into the new motion events.

The main trick is that you need to have some UIView (not UIViewController) that you want as firstResponder to receive the shake event messages. Here's the code that you can use in any UIView to get shake events:

@implementation ShakingView

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if ( event.subtype == UIEventSubtypeMotionShake )
    {
        // Put in code here to handle shake
    }

    if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )
        [super motionEnded:motion withEvent:event];
}

- (BOOL)canBecomeFirstResponder
{ return YES; }

@end

You can easily transform any UIView (even system views) into a view that can get the shake event simply by subclassing the view with only these methods (and then selecting this new type instead of the base type in IB, or using it when allocating a view).

In the view controller, you want to set this view to become first responder:

- (void) viewWillAppear:(BOOL)animated
{
    [shakeView becomeFirstResponder];
    [super viewWillAppear:animated];
}
- (void) viewWillDisappear:(BOOL)animated
{
    [shakeView resignFirstResponder];
    [super viewWillDisappear:animated];
}

Don't forget that if you have other views that become first responder from user actions (like a search bar or text entry field) you'll also need to restore the shaking view first responder status when the other view resigns!

This method works even if you set applicationSupportsShakeToEdit to NO.

In my case I just forgot to add nativeQuery = true

@Query( value = "some sql query ...", nativeQuery = true)

For Spring Boot with Spring Data JPA

If this is an ASP.NET app why not use Server.HtmlEncode() ?

Ctrl + Alt + MouseWheel will work in Visual Studio 2015.

It's a subtle difference, but this works fine for me:

$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);

Notice, the difference between getColumnDimensionByColumn and getColumnDimension

Also, I'm not even setting AutoSize and it works fine.

If you are using T-SQL then it appears from previous posts that UNION removes duplicates. But if you are not, you could use distinct. This doesn't quite feel right to me either but it could get you the result you are looking for

SELECT DISTINCT *
FROM
(
select * from calls
left join users a on calls.assigned_to= a.user_id
where a.dept = 4 
union
select * from calls
left join users r on calls.requestor_id= r.user_id
where r.dept = 4
)a

This is correct. You can also do :

A[] a = new A[] { new A("args"), new A("other args"), .. };

This syntax can also be used to create and initialize an array anywhere, such as in a method argument:

someMethod( new A[] { new A("args"), new A("other args"), . . } )

If your data is already in array form, it's really simple using jQuery:

 $(data.msg).each(function()
 {
     alert(this.value);
     alert(this.label);

     //this refers to the current item being iterated over

     var option = $('<option />');
     option.attr('value', this.value).text(this.label);

     $('#myDropDown').append(option);
 });

.ajax() is more flexible than .getJSON() - for one, getJson is targeted specifically as a GET request to retrieve json; ajax() can request on any verb to get back any content type (although sometimes that's not useful). getJSON internally calls .ajax().

Keep your scripts right before </body>. Async can be used with scripts located there in a few circumstances (see discussion below). Defer won't make much of a difference for scripts located there because the DOM parsing work has pretty much already been done anyway.

Here's an article that explains the difference between async and defer: http://peter.sh/experiments/asynchronous-and-deferred-javascript-execution-explained/.

Your HTML will display quicker in older browsers if you keep the scripts at the end of the body right before </body>. So, to preserve the load speed in older browsers, you don't want to put them anywhere else.

If your second script depends upon the first script (e.g. your second script uses the jQuery loaded in the first script), then you can't make them async without additional code to control execution order, but you can make them defer because defer scripts will still be executed in order, just not until after the document has been parsed. If you have that code and you don't need the scripts to run right away, you can make them async or defer.

You could put the scripts in the <head> tag and set them to defer and the loading of the scripts will be deferred until the DOM has been parsed and that will get fast page display in new browsers that support defer, but it won't help you at all in older browsers and it isn't really any faster than just putting the scripts right before </body> which works in all browsers. So, you can see why it's just best to put them right before </body>.

Async is more useful when you really don't care when the script loads and nothing else that is user dependent depends upon that script loading. The most often cited example for using async is an analytics script like Google Analytics that you don't want anything to wait for and it's not urgent to run soon and it stands alone so nothing else depends upon it.

Usually the jQuery library is not a good candidate for async because other scripts depend upon it and you want to install event handlers so your page can start responding to user events and you may need to run some jQuery-based initialization code to establish the initial state of the page. It can be used async, but other scripts will have to be coded to not execute until jQuery is loaded.

I've made an example for you showing how this could be done.

Notice the js but also that I changed #value into an input element

<input id="value" type="hidden" style="width:300px"/>

and that I am triggering the change event for getting the initial values

$('#attribute').select2().on('change', function() {
    $('#value').select2({data:data[$(this).val()]});
}).trigger('change');

Code Example

Edit:

In the current version of select2 the class attribute is being transferred from the hidden input into the root element created by select2, even the select2-offscreen class which positions the element way outside the page limits.

To fix this problem all that's needed is to add removeClass('select2-offscreen') before applying select2 a second time on the same element.

$('#attribute').select2().on('change', function() {
    $('#value').removeClass('select2-offscreen').select2({data:data[$(this).val()]});
}).trigger('change');

I've added a new Code Example to address this issue.

This is the best solution I found so far.

in blade

@if($mentors->count() == 0)
    <td colspan="5" class="text-center">
        Nothing Found
    </td>
@endif

in controller

if ($mentors->count() == 0) {
    return "Nothing Found";
}

If I understand your question correctly you do want the lines after TERMINATE, not including the TERMINATE-line. awk can do this in a simple way:

awk '{if(found) print} /TERMINATE/{found=1}' your_file

Explanation:

1. Although not best practice you could rely on the fact that all vars defaults to 0 or the empty string if not defined. So the first expression (if(found) print) will not print anything to start off with.
2. After the printing is done we check if the this is the starter-line (that should not be included).

This will print all lines after the TERMINATE-line.

Generalization:

• You have a file with start- and end-lines and you want the lines between those lines excluding the start- and end-lines.
• start- and end-lines could be defined by a regular expression matching the line.

Example:

$ cat ex_file.txt 
not this line
second line
START
A good line to include
And this line
Yep
END
Nope more
...
never ever
$ awk '/END/{found=0} {if(found) print} /START/{found=1}' ex_file.txt 
A good line to include
And this line
Yep
$

Explanation:

1. If the end-line is found no printing should be done. Note that this check is done before the actual printing to exclude the end-line from the result.
2. Print the current line if found is set.
3. If the start-line is found then set found=1 so that the following lines are printed. Note that this check is done after the actual printing to exclude the start-line from the result.

Notes:

• The code rely on the fact that all awk-vars defaults to 0 or the empty string if not defined. This is valid but may not be best practice so you could add a BEGIN{found=0} to the start of the awk-expression.
• If multiple start-end-blocks is found they are all printed.

First, I am copying all values of arrays into a single array then I am removing duplicates values into the array. Line 12, explaining if same number occur more than time then put some extra garbage value into "j" position. At the end, traverse from start-end and check if same garbage value occur then discard.

public class Union {
public static void main(String[] args){

    int arr1[]={1,3,3,2,4,2,3,3,5,2,1,99};
    int arr2[]={1,3,2,1,3,2,4,6,3,4};
    int arr3[]=new int[arr1.length+arr2.length];

    for(int i=0;i<arr1.length;i++)
        arr3[i]=arr1[i];

    for(int i=0;i<arr2.length;i++)
        arr3[arr1.length+i]=arr2[i];
    System.out.println(Arrays.toString(arr3));

    for(int i=0;i<arr3.length;i++)
    {
        for(int j=i+1;j<arr3.length;j++)
        {
            if(arr3[i]==arr3[j])
                arr3[j]=99999999;          //line  12
        }
    }
    for(int i=0;i<arr3.length;i++)
    {
        if(arr3[i]!=99999999)
            System.out.print(arr3[i]+" ");
    }
}   
}

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

$('.select_continent').click(function () {
    alert($(this).attr('value'));
});

I saw a lot of answers here but I didn't try any of them. I've just created the filter as in the following code.

import org.springframework.context.annotation.Configuration;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import java.io.IOException;

@WebFilter(urlPatterns = "/Admin")
@Configuration
public class AdminFilter implements Filter{
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse  servletResponse, FilterChain filterChain) throws IOException, ServletException      {
    System.out.println("happened");

    }

    @Override
    public void destroy() {

    }
}

And leaved the remaining Spring Boot application as it was.

It has 2 purposes.

yentup has given the first one.

It's used for raising your own errors.

if something:
    raise Exception('My error!')

The second is to reraise the current exception in an exception handler, so that it can be handled further up the call stack.

try:
  generate_exception()
except SomeException as e:
  if not can_handle(e):
    raise
  handle_exception(e)

Before making the npm build,
1) Go to your React project root folder and open package.json.
2) Add "homepage" attribute to package.json

• if you want to provide absolute path

  "homepage": "http://hostName.com/appLocation",
  "name": "react-app",
  "version": "1.1.0",
  

• if you want to provide relative path

  "homepage": "./",
  "name": "react-app",
  

  Using relative path method may warn a syntax validation error in your IDE. But the build is made without any errors during compilation.

3) Save the package.json , and in terminal run npm run-script build
4) Copy the contents of build/ folder to your server directory.

PS: It is easy to use relative path method if you want to change the build file location in your server frequently.

Unfortunately you can't use that tuple assignment syntax in (ECMA|Java)Script.

EDIT: Someone linked to Mozilla/JS 1.7 - this wouldn't work cross-browser but if that is not required then there's your answer.

Xcode 8 and Swift 3.0

Using URLSession:

 let url = URL(string:"Download URL")!
 let req = NSMutableURLRequest(url:url)
 let config = URLSessionConfiguration.default
 let session = URLSession(configuration: config, delegate: self, delegateQueue: OperationQueue.main)

 let task : URLSessionDownloadTask = session.downloadTask(with: req as URLRequest)
task.resume()

URLSession Delegate call:

func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {

}


func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, 
didWriteData bytesWritten: Int64, totalBytesWritten writ: Int64, totalBytesExpectedToWrite exp: Int64) {
                   print("downloaded \(100*writ/exp)" as AnyObject)

}

func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL){

}

Using Block GET/POST/PUT/DELETE:

 let request = NSMutableURLRequest(url: URL(string: "Your API URL here" ,param: param))!,
        cachePolicy: .useProtocolCachePolicy,
        timeoutInterval:"Your request timeout time in Seconds")
    request.httpMethod = "GET"
    request.allHTTPHeaderFields = headers as? [String : String] 

    let session = URLSession.shared

    let dataTask = session.dataTask(with: request as URLRequest) {data,response,error in
        let httpResponse = response as? HTTPURLResponse

        if (error != nil) {
         print(error)
         } else {
         print(httpResponse)
         }

        DispatchQueue.main.async {
           //Update your UI here
        }

    }
    dataTask.resume()

Working fine for me.. try it 100% result guarantee

You can also use .split("[|]").

(I used this instead of .split("\\|"), which didn't work for me.)

The result produced by the Query is having no of rows that need proper handling this issue can be resolved if you provide the valid handler in the query like 1. limiting the query to return one single row 2. this can also be done by providing "select max(column)" that will return the single row

In tables I have used \footnotetext.

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

Write a simple server python server listening on a port (say 8080), bind the port -p 8080:8080 with the container, make a HTTP request to localhost:8080 to ask the python server running shell scripts with popen, run a curl or writing code to make a HTTP request curl -d '{"foo":"bar"}' localhost:8080

#!/usr/bin/python
from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer

                post_body = self.rfile.read(content_len)
                self.send_response(200)
                self.end_headers()
                data = json.loads(post_body)

                # Use the post data

                p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
                p_status = p.wait()
                (output, err) = p.communicate()
                print "Command output : ", output

This works if the dll is .net or Win32. Reflection methods only work if the dll is .net. Also, if you use reflection, you have the overhead of loading the whole dll into memory. The below method does not load the assembly into memory.

// Get the file version.
FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(@"C:\MyAssembly.dll");

// Print the file name and version number.
Console.WriteLine("File: " + myFileVersionInfo.FileDescription + '\n' +
                  "Version number: " + myFileVersionInfo.FileVersion);

In AppDelegate you can write like this...

var window: UIWindow?

fileprivate let navigationCtrl = UINavigationController()

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    self.createWindow()

    self.showLoginVC()

    return true
}

func createWindow() {
    let screenSize = UIScreen.main.bounds
    self.window = UIWindow(frame: screenSize)
    self.window?.backgroundColor = UIColor.white
    self.window?.makeKeyAndVisible()
    self.window?.rootViewController = navigationCtrl
}

func showLoginVC() {
    let storyboardBundle = Bundle.main
    // let storyboardBundle = Bundle(for: ClassName.self) // if you are not using main application, means may be you are crating a framework or library you can use this statement instead
    let storyboard = UIStoryboard(name: "LoginVC", bundle: storyboardBundle)
    let loginVC = storyboard.instantiateViewController(withIdentifier: "LoginVC") as! LoginVC
    navigationCtrl.pushViewController(loginVC, animated: false)
}

You can use this OverlayContainer. The trick is to use absolute with 100% size. Check below an example:

// @flow

import React from 'react'
import { View, StyleSheet } from 'react-native'

type Props = {
  behind: React.Component,
  front: React.Component,
  under: React.Component
}

// Show something on top of other
export default class OverlayContainer extends React.Component<Props> {
  render() {
    const { behind, front, under } = this.props

    return (
      <View style={styles.container}>
        <View style={styles.center}>
          <View style={styles.behind}>
            {behind}
          </View>
          {front}
        </View>
        {under}
      </View>
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    height: '100%',
    justifyContent: 'center',
  },
  center: {
    width: '100%',
    height: '100%',
    alignItems: 'center',
    justifyContent: 'center',
  },
  behind: {
    alignItems: 'center',
    justifyContent: 'center',
    position: 'absolute',
    left: 0,
    top: 0,
    width: '100%',
    height: '100%'
  }
})

Options to avoid using SecurityContextHolder in tests:

• Option 1: use mocks - I mean mock SecurityContextHolder using some mock library - EasyMock for example
• Option 2: wrap call SecurityContextHolder.get... in your code in some service - for example in SecurityServiceImpl with method getCurrentPrincipal that implements SecurityService interface and then in your tests you can simply create mock implementation of this interface that returns the desired principal without access to SecurityContextHolder.

Generic solution extracting the first "n" words of refcell string into a new string of "x" number of characters

=LEFT(SUBSTITUTE(***refcell***&" "," ",REPT(" ",***x***),***n***),***x***)

Assuming A1 has text string to extract, the 1st word extracted to a 15 character result

=LEFT(SUBSTITUTE(A1&" "," ",REPT(" ",15),1),15)

This would result in "Toronto" being returned to a 15 character string. 1st 2 words extracted to a 30 character result

=LEFT(SUBSTITUTE(A1&" "," ",REPT(" ",30),2),30)

would result in "Toronto is" being returned to a 30 character string

The error is due to executing long running operations in main thread,You can easily rectify the problem by using AsynTask or Thread. You can checkout this library AsyncHTTPClient for better handling.

AsyncHttpClient client = new AsyncHttpClient();
client.get("http://www.google.com", new AsyncHttpResponseHandler() {

    @Override
    public void onStart() {
        // Called before a request is started
    }

    @Override
    public void onSuccess(int statusCode, Header[] headers, byte[] response) {
        // Called when response HTTP status is "200 OK"
    }

    @Override
    public void onFailure(int statusCode, Header[] headers, byte[] errorResponse, Throwable e) {
        // Called when response HTTP status is "4XX" (for example, 401, 403, 404)
    }

    @Override
    public void onRetry(int retryNo) {
        // Called when request is retried
    }
});

Possible solutions -
1.Make sure that you don't have any other element with name/id as submit.
2.Try to call the function as onClick = "return submitAction();"
3.document.getElementById("form-name").submit();

A few wrinkles that I don't see being addressed in other answers:

1. the element can contain multiple levels of child nodes (e.g. child nodes that have child nodes that have child nodes...)
2. a selection can consist of different start and end positions (e.g. multiple chars are selected)
3. the node containing a Caret start/end may not be either the element or its direct children

Here's a way to get start and end positions as offsets to the element's textContent value:

// node_walk: walk the element tree, stop when func(node) returns false
function node_walk(node, func) {
  var result = func(node);
  for(node = node.firstChild; result !== false && node; node = node.nextSibling)
    result = node_walk(node, func);
  return result;
};

// getCaretPosition: return [start, end] as offsets to elem.textContent that
//   correspond to the selected portion of text
//   (if start == end, caret is at given position and no text is selected)
function getCaretPosition(elem) {
  var sel = window.getSelection();
  var cum_length = [0, 0];

  if(sel.anchorNode == elem)
    cum_length = [sel.anchorOffset, sel.extentOffset];
  else {
    var nodes_to_find = [sel.anchorNode, sel.extentNode];
    if(!elem.contains(sel.anchorNode) || !elem.contains(sel.extentNode))
      return undefined;
    else {
      var found = [0,0];
      var i;
      node_walk(elem, function(node) {
        for(i = 0; i < 2; i++) {
          if(node == nodes_to_find[i]) {
            found[i] = true;
            if(found[i == 0 ? 1 : 0])
              return false; // all done
          }
        }

        if(node.textContent && !node.firstChild) {
          for(i = 0; i < 2; i++) {
            if(!found[i])
              cum_length[i] += node.textContent.length;
          }
        }
      });
      cum_length[0] += sel.anchorOffset;
      cum_length[1] += sel.extentOffset;
    }
  }
  if(cum_length[0] <= cum_length[1])
    return cum_length;
  return [cum_length[1], cum_length[0]];
}

I managed to make it work with alpha28 like this:

import {Component, View} from 'angular2/angular2';

@Component({
  selector: 'circle', 
  properties: ['color: color'],
})
@View({
    template: `<style>
    .circle{
        width:50px;
        height: 50px;
        border-radius: 25px;
    }
</style>
<div class="circle" [style.background-color]="changeBackground()">
    <content></content>
</div>
`
})
export class Circle {
    color;

    constructor(){
    }

    changeBackground(): string {
        return this.color;
    }

Found the answer here: http://www.digitallycreated.net/Blog/59/locally-publishing-a-vs2010-asp.net-web-application-using-msbuild

Visual Studio 2010 has great new Web Application Project publishing features that allow you to easy publish your web app project with a click of a button. Behind the scenes the Web.config transformation and package building is done by a massive MSBuild script that’s imported into your project file (found at: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets). Unfortunately, the script is hugely complicated, messy and undocumented (other then some oft-badly spelled and mostly useless comments in the file). A big flowchart of that file and some documentation about how to hook into it would be nice, but seems to be sadly lacking (or at least I can’t find it).

Unfortunately, this means performing publishing via the command line is much more opaque than it needs to be. I was surprised by the lack of documentation in this area, because these days many shops use a continuous integration server and some even do automated deployment (which the VS2010 publishing features could help a lot with), so I would have thought that enabling this (easily!) would be have been a fairly main requirement for the feature.

Anyway, after digging through the Microsoft.Web.Publishing.targets file for hours and banging my head against the trial and error wall, I’ve managed to figure out how Visual Studio seems to perform its magic one click “Publish to File System” and “Build Deployment Package” features. I’ll be getting into a bit of MSBuild scripting, so if you’re not familiar with MSBuild I suggest you check out this crash course MSDN page.

Publish to File System

The VS2010 Publish To File System Dialog Publish to File System took me a while to nut out because I expected some sensible use of MSBuild to be occurring. Instead, VS2010 does something quite weird: it calls on MSBuild to perform a sort of half-deploy that prepares the web app’s files in your project’s obj folder, then it seems to do a manual copy of those files (ie. outside of MSBuild) into your target publish folder. This is really whack behaviour because MSBuild is designed to copy files around (and other build-related things), so it’d make sense if the whole process was just one MSBuild target that VS2010 called on, not a target then a manual copy.

This means that doing this via MSBuild on the command-line isn’t as simple as invoking your project file with a particular target and setting some properties. You’ll need to do what VS2010 ought to have done: create a target yourself that performs the half-deploy then copies the results to the target folder. To edit your project file, right click on the project in VS2010 and click Unload Project, then right click again and click Edit. Scroll down until you find the Import element that imports the web application targets (Microsoft.WebApplication.targets; this file itself imports the Microsoft.Web.Publishing.targets file mentioned earlier). Underneath this line we’ll add our new target, called PublishToFileSystem:

<Target Name="PublishToFileSystem"
        DependsOnTargets="PipelinePreDeployCopyAllFilesToOneFolder">
    <Error Condition="'$(PublishDestination)'==''"
           Text="The PublishDestination property must be set to the intended publishing destination." />
    <MakeDir Condition="!Exists($(PublishDestination))"
             Directories="$(PublishDestination)" />

    <ItemGroup>
        <PublishFiles Include="$(_PackageTempDir)\**\*.*" />
    </ItemGroup>

    <Copy SourceFiles="@(PublishFiles)"
          DestinationFiles="@(PublishFiles->'$(PublishDestination)\%(RecursiveDir)%(Filename)%(Extension)')"
          SkipUnchangedFiles="True" />
</Target>

This target depends on the PipelinePreDeployCopyAllFilesToOneFolder target, which is what VS2010 calls before it does its manual copy. Some digging around in Microsoft.Web.Publishing.targets shows that calling this target causes the project files to be placed into the directory specified by the property _PackageTempDir.

The first task we call in our target is the Error task, upon which we’ve placed a condition that ensures that the task only happens if the PublishDestination property hasn’t been set. This will catch you and error out the build in case you’ve forgotten to specify the PublishDestination property. We then call the MakeDir task to create that PublishDestination directory if it doesn’t already exist.

We then define an Item called PublishFiles that represents all the files found under the _PackageTempDir folder. The Copy task is then called which copies all those files to the Publish Destination folder. The DestinationFiles attribute on the Copy element is a bit complex; it performs a transform of the items and converts their paths to new paths rooted at the PublishDestination folder (check out Well-Known Item Metadata to see what those %()s mean).

To call this target from the command-line we can now simply perform this command (obviously changing the project file name and properties to suit you):

msbuild Website.csproj "/p:Platform=AnyCPU;Configuration=Release;PublishDestination=F:\Temp\Publish" /t:PublishToFileSystem

I took Fredrik's method and modified the return type.

This way, the method supports deferred execution like other LINQ methods.

EDIT: If this wasn't clear, any usage of this method must end with ToList() or any other way to force the method to work on the complete enumerable. Otherwise, the action would not be performed!

public static IEnumerable<T> ForEach<T>(this IEnumerable<T> enumeration, Action<T> action)
{
    foreach (T item in enumeration)
    {
        action(item);
        yield return item;
    }
}

And here's the test to help see it:

[Test]
public void TestDefferedExecutionOfIEnumerableForEach()
{
    IEnumerable<char> enumerable = new[] {'a', 'b', 'c'};

    var sb = new StringBuilder();

    enumerable
        .ForEach(c => sb.Append("1"))
        .ForEach(c => sb.Append("2"))
        .ToList();

    Assert.That(sb.ToString(), Is.EqualTo("121212"));
}

If you remove the ToList() in the end, you will see the test failing since the StringBuilder contains an empty string. This is because no method forced the ForEach to enumerate.

check this Twig Reference.

You can do it that simple:

{% if (a or b) %}
    ...
{% endif %}

So if you actually want to find executable file types (e.g. scripts, ELF binaries etc.. etc..) not merely files with execution permission then you probably want to do something more like this (where the current directory . can be replaced with whatever directory you want):

 gfind . -type f -exec bash -c '[[ $(file -b "'{}'") == *" executable "* ]] ' \; -print

Or for those of you who aren't using macports (linux users) or otherwise have gnu find installed as find you want:

 find . -type f -exec bash -c '[[ $(file -b "'{}'") == *" executable "* ]] ' \; -print

Though if you are on OS X it comes with a little utility hidden somewhere called is_exec that basically bundles up that little test for you so you can shorten the command line if you find it. But this way is more flexible as you can easily replace the == test with the =~ test and use it to check for more complex properties like executable plain text files or whatever other info your file command returns.

The exact rules for quotation here are pretty opaque so I just end up working it out by trial and error but I'd love to hear the right explanation.

You can't style the drop down box itself, only the input field. The box is rendered by the operating system.

If you want more control over the look of your input fields, you can always look into JavaScript solutions.

If, however, your intent was to remove the border from the input itself, your selector is wrong. Try this instead:

select#xyz {
    border: none;
}

Its fine to just do char **strings;, char **strings = NULL, or char **strings = {NULL}

but to initialize it you'd have to use malloc:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main(){
    // allocate space for 5 pointers to strings
    char **strings = (char**)malloc(5*sizeof(char*));
    int i = 0;
    //allocate space for each string
    // here allocate 50 bytes, which is more than enough for the strings
    for(i = 0; i < 5; i++){
        printf("%d\n", i);
        strings[i] = (char*)malloc(50*sizeof(char));
    }
    //assign them all something
    sprintf(strings[0], "bird goes tweet");
    sprintf(strings[1], "mouse goes squeak");
    sprintf(strings[2], "cow goes moo");
    sprintf(strings[3], "frog goes croak");
    sprintf(strings[4], "what does the fox say?");
    // Print it out
    for(i = 0; i < 5; i++){
        printf("Line #%d(length: %lu): %s\n", i, strlen(strings[i]),strings[i]);
    } 
    //Free each string
    for(i = 0; i < 5; i++){
        free(strings[i]);
    }
    //finally release the first string
    free(strings);
    return 0;
}

In order to make a pull request you need to do the following steps:

1. Fork a repository (to which you want to make a pull request). Just click the fork button the the repository page and you will have a separate github repository preceded with your github username.
2. Clone the repository to your local machine. The Github software that you installed on your local machine can do this for you. Click the clone button beside the repository name.
3. Make local changes/commits to the files
4. sync the changes
5. go to your github forked repository and click the "Compare & Review" green button besides the branch button. (The button has icon - no text)
6. A new page will open showing your changes and then click the pull request link, that will send the request to the original owner of the repository you forked.

It took me a while to figure this, hope this will help someone.

Starting from pandas 0.14 (released end of May 2014), postgresql is supported. The sql module now uses sqlalchemy to support different database flavors. You can pass a sqlalchemy engine for a postgresql database (see docs). E.g.:

from sqlalchemy import create_engine
engine = create_engine('postgresql://username:password@localhost:5432/mydatabase')
df.to_sql('table_name', engine)

You are correct that in pandas up to version 0.13.1 postgresql was not supported. If you need to use an older version of pandas, here is a patched version of pandas.io.sql: https://gist.github.com/jorisvandenbossche/10841234.
I wrote this a time ago, so cannot fully guarantee that it always works, buth the basis should be there). If you put that file in your working directory and import it, then you should be able to do (where con is a postgresql connection):

import sql  # the patched version (file is named sql.py)
sql.write_frame(df, 'table_name', con, flavor='postgresql')

An alternative solution:

div[class|='tocolor'] will match for values of the "class" attribute that begin with "tocolor-", including "tocolor-1", "tocolor-2", etc.

Beware that this won't match

<div class="foo tocolor-">

Reference: https://www.w3.org/TR/css3-selectors/#attribute-representation

[att|=val]

Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D)

Go to the Servers project in eclipse, under your runtime server configuration(in my case Tomcat v7.0 Server at localhost-config) go to server.xml file then search for <context> tag, normally you will find more than one context tag, delete them and run your application in the appropriate server that will work now.

in my case i have found duplicate Context tag :

<Context docBase="my-project" path="/my-project" reloadable="true" source="org.eclipse.jst.jee.server:my-project"/&gt;&lt;Context docBase="my-project" path="/smartphone-selfcare" reloadable="true" source="org.eclipse.jst.jee.server:my-project"/></Host>

First solution - simply change the extension of your .json file to .ts and add export default at the beginning of the file, like so:

export default {
   property: value;
}

Then you can just simply import the file without the need to add typings, like so:

import data from 'data';

Second solution get the json via HttpClient.

Inject HttpClient into your component, like so:

export class AppComponent  {
  constructor(public http: HttpClient) {}
}

and then use this code:

this.http.get('/your.json').subscribe(data => {
  this.results = data;
});

https://angular.io/guide/http

This solution has one clear adventage over other solutions provided here - it doesn't require you to rebuild entire application if your json will change (it's loaded dynamically from a separate file, so you can modify only that file).

You can use now() like:

Select data from tablename where datetime >= "01-01-2009 00:00:00" and datetime <= now();

If you don't want to use temporary tables here is a split string like function you can use

SET @Array = 'one,two,three,four';
SET @ArrayIndex = 2;
SELECT CASE 
    WHEN @Array REGEXP CONCAT('((,).*){',@ArrayIndex,'}') 
    THEN SUBSTRING_INDEX(SUBSTRING_INDEX(@Array,',',@ArrayIndex+1),',',-1) 
    ELSE NULL
END AS Result;

• SUBSTRING_INDEX(string, delim, n) returns the first n
• SUBSTRING_INDEX(string, delim, -1) returns the last only
• REGEXP '((delim).*){n}' checks if there are n delimiters (i.e. you are in bounds)

$(window).mouseleave(function(event) {
  if (event.toElement == null) {
    //Do something
  }
})

This might be a bit hacky but it will only trigger when the mouse leaves the window. I kept catching child events and this resolved it

quite simple:

ul.yourlist li { float:left; }

or

ul.yourlist li { display:inline; }

Create a breakpoint as you normally would, right click the red dot and select "condition".

If you're using Eclipse PDT, this is done by opening up the PHP explorer view, then clicking the upside-down triangle in the top-right of that window. A context window appears, and the filters option is available there. Clicking the Filters menu option opens a new window, where .* files can be unchecked, thus allowing the editing of .htaccess files.

I searched forever for this, so I'm sorta answering my own question here. I'm sure someone else will have the same problem too, so I hope this helps someone else as well.

Another way to reset the values (for multiple selected elements) could be this:

$("selector").each(function(){

    /*Perform any check and validation if needed for each item */

    /*Use "this" to handle the element in javascript or "$(this)" to handle the element with jquery */

    this.selectedIndex=0;

});

The way to do this using py2exe is to use the bundle_files option in your setup.py file. For a single file you will want to set bundle_files to 1, compressed to True, and set the zipfile option to None. That way it creates one compressed file for easy distribution.

Here is a more complete description of the bundle_file option quoted directly from the py2exe site*

Using "bundle_files" and "zipfile"

An easier (and better) way to create single-file executables is to set bundle_files to 1 or 2, and to set zipfile to None. This approach does not require extracting files to a temporary location, which provides much faster program startup.

Valid values for bundle_files are:

• 3 (default) don't bundle
• 2 bundle everything but the Python interpreter
• 1 bundle everything, including the Python interpreter

If zipfile is set to None, the files will be bundle within the executable instead of library.zip.

Here is a sample setup.py:

from distutils.core import setup
import py2exe, sys, os

sys.argv.append('py2exe')

setup(
    options = {'py2exe': {'bundle_files': 1, 'compressed': True}},
    windows = [{'script': "single.py"}],
    zipfile = None,
)

Not sure if this will help in your context...

Can the soap object be cast as a BindingProvider ?

MyWebServiceSoap soap;
MyWebService service = new MyWebService("http://www.google.com");
soap = service.getMyWebServiceSoap();
// set timeouts here
((BindingProvider)soap).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000);
    soap.sendRequestToMyWebService();

On the other hand if you are wanting to set the timeout on the initialization of the MyWebService object then this will not help.

This worked for me when wanting to timeout the individual WebService calls.

With the api you can use

var table = $('#example').DataTable();

table.column( 0 ).visible( false );

Look this info:

Inspired by Enigmativity's answer - let's assume you have two (or more) classes, like

public class Bar { }
public class Square { }

and you want to call the method Foo<T> with Bar and Square, which is declared as

public class myClass
{
    public void Foo<T>(T item)
    {
        Console.WriteLine(typeof(T).Name);
    }
}

Then you can implement an Extension method like:

public static class Extension
{
    public static void InvokeFoo<T>(this T t)
    {
        var fooMethod = typeof(myClass).GetMethod("Foo");
        var tType = typeof(T);
        var fooTMethod = fooMethod.MakeGenericMethod(new[] { tType });
        fooTMethod.Invoke(new myClass(), new object[] { t });
    }
}

With this, you can simply invoke Foo like:

var objSquare = new Square();
objSquare.InvokeFoo();

var objBar = new Bar();
objBar.InvokeFoo();

which works for every class. In this case, it will output:

Square
Bar

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

<div>
  <div class="a">
    A
  </div>
</div>?


$(window).scroll(function() {
  if ($(this).scrollTop() > 0) {
    $('.a').fadeOut();
  } else {
    $('.a').fadeIn();
  }
});

Sample

ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, and WRITE_EXTERNAL_STORAGE are all part of the Android 6.0 runtime permission system. In addition to having them in the manifest as you do, you also have to request them from the user at runtime (using requestPermissions()) and see if you have them (using checkSelfPermission()).

One workaround in the short term is to drop your targetSdkVersion below 23.

But, eventually, you will want to update your app to use the runtime permission system.

For example, this activity works with five permissions. Four are runtime permissions, though it is presently only handling three (I wrote it before WRITE_EXTERNAL_STORAGE was added to the runtime permission roster).

(from this sample project)

For the requestPermissions() function, should the parameters just be "ACCESS_COARSE_LOCATION"? Or should I include the full name "android.permission.ACCESS_COARSE_LOCATION"?

I would use the constants defined on Manifest.permission, as shown above.

Also, what is the request code?

That will be passed back to you as the first parameter to onRequestPermissionsResult(), so you can tell one requestPermissions() call from another.

find /abs/path/ -name '*.js'

Edit: As Brian points out, add -type f if you want only plain files, and not directories, links, etc.

Assuming that your branch is called master both here and remotely, and that your remote is called origin you could do:

git reset --hard <commit-hash>
git push -f origin master

However, you should avoid doing this if anyone else is working with your remote repository and has pulled your changes. In that case, it would be better to revert the commits that you don't want, then push as normal.

You can do this with a list comprehension and index()

tuple_list = [("pineapple", 5), ("cherry", 7), ("kumquat", 3), ("plum", 11)]
[x[0] for x in tuple_list].index("kumquat")
2
[x[1] for x in tuple_list].index(7)
1

It's better, if you use two div containers in HTML .

As Shown Below:

HTML:

<div id="container1">
    <div id="container2">
        // Content here
    </div>
</div>

CSS:

 #container1{
    height: 100%;
    width: 100%;
    overflow: hidden;
}

 #container2{
    height: 100%;
    width: 100%;
    overflow: auto;
    padding-right: 20px;
}

I know I'm a bit late to the party, but if you can put up with having the lines left-justified, one hack is to put the pipes before the items and then put a mask over the left edge, basically like so:

li::before {
  content: " | ";
  white-space: nowrap;
}

ul, li {
  display: inline;
}

.mask {
  width:4px;
  position: absolute;
  top:8px; //position as needed
}

more complete example: http://jsbin.com/hoyaduxi/1/edit

The LDF is the transaction log. It keeps a record of everything done to the database for rollback purposes.

You do not want to delete, but you can shrink it with the dbcc shrinkfile command. You can also right-click on the database in SQL Server Management Studio and go to Tasks > Shrink.

I've found that these problems are often best solved at the server layer. Do you have access to an .htaccess file where you could place a redirect rule? If so:

RedirectPermanent /path/to/page http://uri.com

This redirect will also serve a "301 Moved Permanently" response to indicate that the Flickr page (for example) is the permanent URI for the old page.

If this is not possible, you can create a custom page template for each page in question, and add the following PHP code to the top of the page template (actually, this is all you need in the template:

In case anyone else needs to add padding to something with background-image and background-size: contain or cover, I used the following which is a nice way of doing it. You can replace the border-width with 10% or 2vw or whatever you like.

.bg-image {
    background: url("/image/logo.png") no-repeat center #ffffff / contain;
    border: inset 10px transparent;
    box-sizing: border-box;
}

This means you don't have to define a width.

I manually filled NAs by exporting the CSV then editing it and reimporting, as below.

Perhaps one of you experts might explain why this procedure worked so well (the first file had columns with data of types char, INT and num (floating point numbers)), which all became char type after STEP 1; but at the end of STEP 3 R correctly recognized the datatype of each column).

# STEP 1:
MainOptionFile <- read.csv("XLUopt_XLUstk_v3.csv",
                            header=T, stringsAsFactors=FALSE)
#... STEP 2:
TestFrame <- subset(MainOptionFile, str_locate(option_symbol,"120616P00034000") > 0)
write.csv(TestFrame, file = "TestFrame2.csv")
# ...
# STEP 3:
# I made various amendments to `TestFrame2.csv`, including replacing all missing data cells with appropriate numbers. I then read that amended data frame back into R as follows:    
XLU_34P_16Jun12 <- read.csv("TestFrame2_v2.csv",
                            header=T,stringsAsFactors=FALSE)

On arrival back in R, all columns had their correct measurement levels automatically recognized by R!

Even simpler:

body: new URLSearchParams({
      'userName': '[email protected]',
      'password': 'Password!',
      'grant_type': 'password'
    }),

Roc answer is a great help. I would like to add a small block to it:

mRecyclerView.scrollToPosition(mAdapter.getItemCount() - 1);

The language standard simply doesn't allow for it. Labels can only be followed by statements, and declarations do not count as statements in C. The easiest way to get around this is by inserting an empty statement after your label, which relieves you from keeping track of the scope the way you would need to inside a block.

#include <stdio.h>
int main () 
{
    printf("Hello ");
    goto Cleanup;
Cleanup: ; //This is an empty statement.
    char *str = "World\n";
    printf("%s\n", str);
}

If you only want to change the font in the TEXTAREA then you only need to change the changeFont() function in the original code to:

function changeFont(_name) {
    document.getElementById("mytextarea").style.fontFamily = _name;
}

Then selecting a font will change on the font only in the TEXTAREA.

You need to inject mock inside the class you're testing. At the moment you're interacting with the real object, not with the mock one. You can fix the code in a following way:

void testAbc(){
     myClass.myObj = myInteface;
     myClass.abc();
     verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}

although it would be a wiser choice to extract all initialization code into @Before

@Before
void setUp(){
     myClass = new myClass();
     myClass.myObj = myInteface;
}

@Test
void testAbc(){
     myClass.abc();
     verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}

Updating an entry:

A simple increment should do the trick.

UPDATE mytable 
  SET logins = logins + 1 
  WHERE id = 12

Insert new row, or Update if already present:

If you would like to update a previously existing row, or insert it if it doesn't already exist, you can use the REPLACE syntax or the INSERT...ON DUPLICATE KEY UPDATE option (As Rob Van Dam demonstrated in his answer).

Inserting a new entry:

Or perhaps you're looking for something like INSERT...MAX(logins)+1? Essentially you'd run a query much like the following - perhaps a bit more complex depending on your specific needs:

INSERT into mytable (logins) 
  SELECT max(logins) + 1 
  FROM mytable

background-image takes an url as a value. Use either

background-image: url ('/image/btn.png');

or

background: url ('/image/btn.png') no-repeat;

which is a shorthand for

background-image: url ('/image/btn.png');
background-repeat: no-repeat;

Also, you might want to look at the button HTML element for fancy submit buttons.

The unambiguous way to write this is (i.e. increase the 2nd date by 1 and make it <)

select * 
from xxx 
where dates >= '20121026'
  and dates <  '20121028'

If you're using SQL Server 2008 or above, you can safety CAST as DATE while retaining SARGability, e.g.

select * 
from xxx 
where CAST(dates as DATE) between '20121026' and '20121027'

This explicitly tells SQL Server that you are only interested in the DATE portion of the dates column for comparison against the BETWEEN range.

An inheritor of a base class should have an "is a" relationship. Interface represents An "implements a" relationship. So only use a base class when your inheritors will maintain the is a relationship.

We can compile the code of C in Sublime Text and can print some value or strings but it does not accept input from the user. (Till I know... I am sure about compiling but not about output from given input.) If you are using Windows you have to set the environment variables for Sublime Text and GCC compiler.

Change the file content of c:\wamp\alias\phpmyadmin.conf to the following.

Note: You should set the Allow Directive to allow from your local machine for security purposes. The directive Allow from all is insecure and should be limited to your local machine.

<Directory "c:/wamp/apps/phpmyadmin3.4.5/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Deny,Allow
        Allow from all
</Directory>

Here my WAMP installation is in the c:\wamp folder. Change it according to your installation.

Previously, it was like this:

<Directory "c:/wamp/apps/phpmyadmin3.4.5/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Deny,Allow
    Deny from all
    Allow from 127.0.0.1
</Directory>

Modern versions of Apache 2.2 and up will look for a IPv6 loopback instead of a IPv4 loopback (your localhost).

The real problem is that wamp is binding to an IPv6 address. The fix: just add Allow from ::1 - Tiberiu-Ionu? Stan

<Directory "c:/wamp22/apps/phpmyadmin3.5.1/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Deny,Allow
    Deny from all
    Allow from localhost 127.0.0.1 ::1
</Directory>

This will allow only the local machine to access local apps for Apache.

Restart your Apache server after making these changes.

So I haven't been able to get the Mesh Colliders to work. I created a composite collider using simple box colliders and it worked exactly as expected.

Other tests with simple Mesh Colliders have come out the same.

It looks like the best answer is to build a composite collider out of simple box/sphere colliders.

For my specific case I wrote a Wizard that creates a Pipe shaped compound collider.

@script AddComponentMenu("Colliders/Pipe Collider");
class WizardCreatePipeCollider extends ScriptableWizard
{
    public var outterRadius : float = 200;
    public var innerRadius : float = 190;
    public var sections : int = 12;
    public var height : float = 20;

    @MenuItem("GameObject/Colliders/Create Pipe Collider")
    static function CreateWizard()
    {
        ScriptableWizard.DisplayWizard.<WizardCreatePipeCollider>("Create Pipe Collider");
    }

    public function OnWizardUpdate() {
        helpString = "Creates a Pipe Collider";
    }

    public function OnWizardCreate() {
        var theta : float = 360f / sections;
        var width : float = outterRadius - innerRadius;

        var sectionLength : float = 2 * outterRadius * Mathf.Sin((theta / 2) * Mathf.Deg2Rad);

        var container : GameObject = new GameObject("Pipe Collider");
        var section : GameObject;
        var sectionCollider : GameObject;
        var boxCollider : BoxCollider;

        for(var i = 0; i < sections; i++)
        {
            section = new GameObject("Section " + (i + 1));

            sectionCollider = new GameObject("SectionCollider " + (i + 1));
            section.transform.parent = container.transform;
            sectionCollider.transform.parent = section.transform;

            section.transform.localPosition = Vector3.zero;
            section.transform.localRotation.eulerAngles.y = i * theta;

            boxCollider = sectionCollider.AddComponent.<BoxCollider>();
            boxCollider.center = Vector3.zero;
            boxCollider.size = new Vector3(width, height, sectionLength);

            sectionCollider.transform.localPosition = new Vector3(innerRadius + (width / 2), 0, 0);
        }
    }
}

Don't get confused with the concepts of Angular and RxJS

We have pipes concept in Angular and pipe() function in RxJS.

1) Pipes in Angular: A pipe takes in data as input and transforms it to the desired output
https://angular.io/guide/pipes

2) pipe() function in RxJS: You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.
https://angular.io/guide/rx-library (search for pipes in this URL, you can find the same)

So according to your question, you are referring pipe() function in RxJS

This brings up the Team Explorer Changes dialog:


Type in a description- here it's "Stack Overflow Example Commit".
Make a choice of the three options on offer, all of which are explained here.

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers.

Example -

$( document ).on( events, selector, data, handler );

The error you are getting is in line 3. i.e. it is not in

CONSTRAINT no_duplicate_tag UNIQUE (question_id, tag_id)

but earlier:

CREATE TABLE tags
     (
              (question_id, tag_id) NOT NULL,

Correct table definition is like pilcrow showed.

And if you want to add unique on tag1, tag2, tag3 (which sounds very suspicious), then the syntax is:

CREATE TABLE tags (
    question_id INTEGER NOT NULL,
    tag_id SERIAL NOT NULL,
    tag1 VARCHAR(20),
    tag2 VARCHAR(20),
    tag3 VARCHAR(20),
    PRIMARY KEY(question_id, tag_id),
    UNIQUE (tag1, tag2, tag3)
);

or, if you want to have the constraint named according to your wish:

CREATE TABLE tags (
    question_id INTEGER NOT NULL,
    tag_id SERIAL NOT NULL,
    tag1 VARCHAR(20),
    tag2 VARCHAR(20),
    tag3 VARCHAR(20),
    PRIMARY KEY(question_id, tag_id),
    CONSTRAINT some_name UNIQUE (tag1, tag2, tag3)
);

This how I would implement it:

     REGEXP_REPLACE(text,'(^[[:space:]]*|[[:space:]]*$)')

In addition to what have been suggested, setdefault might be useful in situations where you don't want to modify a value that has been already set. For example, when you have duplicate numbers and you want to treat them as one group. In this case, if you encounter a repeated duplicate key which has been already set, you won't update the value of that key. You will keep the first encountered value. As if you are iterating/updating the repeated keys once only.

Here's a code example of recording the index for the keys/elements of a sorted list:

nums = [2,2,2,2,2]
d = {}
for idx, num in enumerate(sorted(nums)):
    # This will be updated with the value/index of the of the last repeated key
    # d[num] = idx # Result (sorted_indices): [4, 4, 4, 4, 4]
    # In the case of setdefault, all encountered repeated keys won't update the key.
    # However, only the first encountered key's index will be set 
    d.setdefault(num,idx) # Result (sorted_indices): [0, 0, 0, 0, 0]

sorted_indices = [d[i] for i in nums]

I spent more time on this than I should have, and haven't tested in IE for obvious reasons. That being said, it's pretty much identical.

If you’re running Jupyter on Python 3, you can set up a Python 2 kernel like this:

In Java 11 we can use Collection.toArray(generator) method. The following code will create a new array of String:

Set<String> set = Set.of("one", "two", "three");
String[] array = set.toArray(String[]::new)

See: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Collection.html#toArray(java.util.function.IntFunction)

System.Threading.Thread.Sleep(50);

Remember though, that doing this in the main GUI thread will block your GUI from updating (it will feel "sluggish")

Just remove the ; to make it work for VB.net as well.

As mentioned in the previous posts, using an HttpServletReqiestWrapper is the way to go, however the missed part in those posts was that apart from overriding the method getParameter(), you should also override other parameter related methods to produce a consistent response. e.g. the value of a param added by the custom request wrapper should also be included in the parameters map returned by the method getParameterMap(). Here is an example:

   public class AddableHttpRequest extends HttpServletRequestWrapper {

    /** A map containing additional request params this wrapper adds to the wrapped request */
    private final Map<String, String> params = new HashMap<>();

    /**
     * Constructs a request object wrapping the given request.
     * @throws java.lang.IllegalArgumentException if the request is null
     */
    AddableHttpRequest(final HttpServletRequest request) {
        super(request)
    }

    @Override
    public String getParameter(final String name) {
        // if we added one with the given name, return that one
        if ( params.get( name ) != null ) {
            return params.get( name );
        } else {
            // otherwise return what's in the original request
            return super.getParameter(name);
        }
    }


    /**
     * *** OVERRIDE THE METHODS BELOW TO REFLECT PARAMETERS ADDED BY THIS WRAPPER ****
     */

    @Override
    public Map<String, String> getParameterMap() {
        // defaulf impl, should be overridden for an approprivate map of request params
        return super.getParameterMap();
    }

    @Override
    public Enumeration<String> getParameterNames() {
        // defaulf impl, should be overridden for an approprivate map of request params names
        return super.getParameterNames();
    }

    @Override
    public String[] getParameterValues(final String name) {
        // defaulf impl, should be overridden for an approprivate map of request params values
        return super.getParameterValues(name);
    }
}

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

The correct parameter to set the maximum length is:

SET @@group_concat_max_len = value_numeric;

value_numeric must be > 1024; by default the group_concat_max_len value is 1024.

It means XML is malformed or the response body is not XML document at all.

var x = {
    a: (window.secreta = 5),
    b: (window.secretb = 6),
    c: window.secreta + window.secretb
};

This is almost identical to @slicedtoad's answer, but doesn't use a function.

Just keep a currentValue variable in your controller that you update on every change. You can then compare that to the new value every time before you update it.'

The idea of using a watch is good as well, but I think a simple variable is the simplest and most logical solution.

You can use Jquery's on method and listen for the scroll event.

Quick fix - make sure all variables which do not get initialized when they are created (eg var num : Int? vs var num = 5) have either a ? or !.

Long answer (reccomended) - read the doc as per mprivat suggests...

Android Studio 3

Make sure you have the latest version of Android Studio. The support library is included by default when you create new projects. If you are adding the Support Library to a project that doesn't have it, then you just need to add a single line to your app module's build.gradle file, and then sync gradle.

build.gradle

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:27.1.1'
} 

It should just be that easy, though there may be some things to note:

• Android Studio should give you a warning nowadays if the support library needs to be updated. Just update the 27.1.1 numbers that I have here to whatever it tells you to. You can also manually check what the latest revision is if you want to.
• The implementation keyword replaces compile that was used in Android Studio 2.x. (What's the difference?)
• There are other support library packages that you may need to include depending on what your app uses (like constraint-layout or recyclerview).
• Make sure that you have the latest updates for everything in the SDK Manager. Go to Tools > SDK Manager.

Documentation

• Support Library
• Support Library Setup
• Support Library Features

I'm betting the problem is that Cygwin is writing Unix line endings (LF) to the file, and you're opening it with a program that expects Windows line-endings (CRLF). To determine if this is the case — and for a bit of a hackish workaround — try:

echo "`date` User `whoami` started the script."$'\r' >> output.log

(where the $'\r' at the end is an extra carriage-return; it, plus the Unix line ending, will result in a Windows line ending).

Try with

$('.handle').css({'left': '300px'});

Instead of

$('.handle').css({'style':'left: 300px'})

I would recommend storing these as numbers in columns of type varchar - one column per "field" (like contry code etc.).

The format should be applied when you interact with a user... that makes it easier to account for format changes for example and will help esp. when your application goes international...

This is it guys! FIXED!

Wait and see: https://bugzilla.mozilla.org/show_bug.cgi?id=649849

or workaround

For those wondering:

https://bugzilla.mozilla.org/show_bug.cgi?id=649849#c59

First, because the bug has a lot of hostile spam in it, it creates a hostile workplace for anyone who gets assigned to this.

Secondly, the person who has the ability to do this (which includes rewriting ) has been allocated to another project (b2g) for the time being and wont have time until that project get nearer to completion.

Third, even when that person has the time again, there is no guarantee that this will be a priority because, despite webkit having this, it breaks the spec for how is supposed to work (This is what I was told, I do not personally know the spec)

Now see https://wiki.mozilla.org/B2G/Schedule_Roadmap ;)

The page no longer exists and the bug hasn't be fixed but an acceptable workaround came from João Cunha, you guys can thank him for now!

I recently moved a site using SimplePie (http://simplepie.org/) from a server that was using PHP 5.2.17 to one that is using PHP 5.3.2. It was after this move that I began receiving a list of error messages such as this one:

Deprecated: Assigning the return value of new by reference is deprecated in .../php/simplepie.inc on line 738

After reviewing several discussions of this issue, I cleared things up by replacing all the instances of =& new with = new in the simplepie.inc file.

I'm not experienced enough to know if this will work in all instances where these error messages are received but it worked in this particular case and it may be worth trying.

onNewIntent() is meant as entry point for singleTop activities which already run somewhere else in the stack and therefore can't call onCreate(). From activities lifecycle point of view it's therefore needed to call onPause() before onNewIntent(). I suggest you to rewrite your activity to not use these listeners inside of onNewIntent(). For example most of the time my onNewIntent() methods simply looks like this:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // getIntent() should always return the most recent
    setIntent(intent);
}

With all setup logic happening in onResume() by utilizing getIntent().

You can give the Open Hardware Monitor a go, although it lacks support for the latest processors.

internal sealed class CpuTemperatureReader : IDisposable
{
    private readonly Computer _computer;

    public CpuTemperatureReader()
    {
        _computer = new Computer { CPUEnabled = true };
        _computer.Open();
    }

    public IReadOnlyDictionary<string, float> GetTemperaturesInCelsius()
    {
        var coreAndTemperature = new Dictionary<string, float>();

        foreach (var hardware in _computer.Hardware)
        {
            hardware.Update(); //use hardware.Name to get CPU model
            foreach (var sensor in hardware.Sensors)
            {
                if (sensor.SensorType == SensorType.Temperature && sensor.Value.HasValue)
                    coreAndTemperature.Add(sensor.Name, sensor.Value.Value);
            }
        }

        return coreAndTemperature;
    }

    public void Dispose()
    {
        try
        {
            _computer.Close();
        }
        catch (Exception)
        {
            //ignore closing errors
        }
    }
}

Download the zip from the official source, extract and add a reference to OpenHardwareMonitorLib.dll in your project.

As has, to some extent, been mentioned before, an enum is a java class with the special condition that its definition must start with at least one "enum constant".

Apart from that, and that enums cant can't be extended or used to extend other classes, an enum is a class like any class and you use it by adding methods below the constant definitions:

public enum MySingleton {
    INSTANCE;

    public void doSomething() { ... }

    public synchronized String getSomething() { return something; }

    private String something;
}

You access the singleton's methods along these lines:

MySingleton.INSTANCE.doSomething();
String something = MySingleton.INSTANCE.getSomething();

The use of an enum, instead of a class, is, as has been mentioned in other answers, mostly about a thread-safe instantiation of the singleton and a guarantee that it will always only be one copy.

And, perhaps, most importantly, that this behavior is guaranteed by the JVM itself and the Java specification.

Here's a section from the Java specification on how multiple instances of an enum instance is prevented:

An enum type has no instances other than those defined by its enum constants. It is a compile-time error to attempt to explicitly instantiate an enum type. The final clone method in Enum ensures that enum constants can never be cloned, and the special treatment by the serialization mechanism ensures that duplicate instances are never created as a result of deserialization. Reflective instantiation of enum types is prohibited. Together, these four things ensure that no instances of an enum type exist beyond those defined by the enum constants.

Worth noting is that after the instantiation any thread-safety concerns must be handled like in any other class with the synchronized keyword etc.

Had same issue today, and noticed that this occurs when owner/group of file is not the one running app that reads key. Maybe is your issue too.

Whenever gcc on the compilation machine and gdb on the testing machine have differing versions, you may be facing debuginfo format incompatibility.

To fix that, try downgrading the debuginfo format:

gcc -gdwarf-3 ...
gcc -gdwarf-2 ...
gcc -gstabs ...
gcc -gstabs+ ...
gcc -gcoff ...
gcc -gxcoff ...
gcc -gxcoff+ ...

Or match gdb to the gcc you're using.

Another approach would be to reset the form using JavaScript right after the form in the HTML:

<form id="myForm">
  <input type="text" value="" name="myTextInput" />
</form>

<script type="text/javascript">
  document.getElementById("myForm").reset();
</script>

You could add this code:

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if ([[UIScreen mainScreen] respondsToSelector: @selector(scale)]) {
            CGSize result = [[UIScreen mainScreen] bounds].size;
            CGFloat scale = [UIScreen mainScreen].scale;
            result = CGSizeMake(result.width * scale, result.height * scale);

            if(result.height == 960) {
                NSLog(@"iPhone 4 Resolution");
            }
            if(result.height == 1136) {
