Alternatively, this solution works with both Apache2 version < 2.4 as well as >= 2.4. Make sure that the "version" module is enabled:

a2enmod version

And then use this code instead:

<IfVersion < 2.4>
    Allow from all
</IfVersion>
<IfVersion >= 2.4>
    Require all granted
</IfVersion>

It turns out the best solution for me here was to just reformat the drive. Once reformatted all these problems were no longer problems.

If all vectors have equal size, create a matrix and plot it. Each column is plotted with a different color automatically Then you can use legend to indicate columns:

data = randn(100, 5);

figure;
plot(data);

legend(cellstr(num2str((1:size(data,2))')))

Or, if you have a cell with kernels names, use

legend(names)

Create black png with lets say 50% transparency. Overlay this on mouseover.

UIActionSheet is deprecated in iOS 8.

I am using following:

// Create the AlertController
let actionSheetController = UIAlertController(title: "Please select", message: "How you would like to utilize the app?", preferredStyle: .ActionSheet)

// Create and add the Cancel action
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
    // Just dismiss the action sheet
}
actionSheetController.addAction(cancelAction)

// Create and add first option action
let takePictureAction = UIAlertAction(title: "Consumer", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_customer", sender: self)
}
actionSheetController.addAction(takePictureAction)

// Create and add a second option action
let choosePictureAction = UIAlertAction(title: "Service provider", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_provider", sender: self)
}
actionSheetController.addAction(choosePictureAction)

// We need to provide a popover sourceView when using it on iPad
actionSheetController.popoverPresentationController?.sourceView = sender as UIView

// Present the AlertController
self.presentViewController(actionSheetController, animated: true, completion: nil)

I think the easiest way to think about this variable like input parameter in lambda expression in C#. I.e. $_ is similar to x in x => Console.WriteLine(x) anonymous function in C#. Consider following examples:

PowerShell:

1,2,3 | ForEach-Object {Write-Host $_}

Prints:

1
2
3

or

1,2,3 | Where-Object {$_ -gt 1}

Prints:

2
3

And compare this with C# syntax using LINQ:

var list = new List<int> { 1, 2, 3 };
list.ForEach( _ => Console.WriteLine( _ ));

Prints:

1
2
3

or

list.Where( _ => _ > 1)
    .ToList()
    .ForEach(s => Console.WriteLine(s));

Prints:

2
3

id is of primitive type int and not an Object. You cannot call methods on a primitive as you are doing here :

id.equals

Try replacing this:

        if (id.equals(list[pos].getItemNumber())){ //Getting error on "equals"

with

        if (id == list[pos].getItemNumber()){ //Getting error on "equals"

I was working on a project that depended on numpy and scipy. In a clean installation of Fedora 23, using a python virtual environment for Python 3.4 (also worked for Python 2.7), and with the following in my setup.py (in the setup() method)

setup_requires=[
    'numpy',
],
install_requires=[
    'numpy',
    'scipy',
],

I found I had to run the following to get pip install -e . to work:

pip install --upgrade pip

and

sudo dnf install atlas-devel gcc-{c++,gfortran} subversion redhat-rpm-config

The redhat-rpm-config is for scipy's use of redhat-hardened-cc1 as opposed to the regular cc1

i did try the above steps for some reason it seams not to be working for me but this was my final solution to my own problem just maybe helpful to any one reading this :

let pst = post.likes.some( (like) => {  //console.log(like.user, req.user.id);
                                     if(like.user.toString() === req.user.id.toString()){
                                         return true
                                     } } )

here post.likes is an array of users who liked a post.

Use:

echo hello
echo.
echo world

Make sure you open the .xcworkspace file not the project file from xCode Project menu when working with pods. That should solve the issue with linking.

just a note: CPLUS_INCLUDE_PATH and C_INCLUDE_PATH are not the equivalent of LD_LIBRARY_PATH. LD_LIBRARY_PATH serves the ld (the dynamic linker at runtime) whereas the equivalent of the former two that serves your C/C++ compiler with the location of libraries is LIBRARY_PATH.

Use glob. There are comprehensive guide how to open all files from dir: PHP: Using functional programming for listing files and directories

you can try this

 ActionBar actionBar = getSupportActionBar();

Use setState in your view to change employed property of state. This is example of React render engine.

 someFunctionWhichChangeParamEmployed(isEmployed) {
      this.setState({
          employed: isEmployed
      });
 }

 getInitialState() {
      return {
          employed: true
      }
 },

 render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <span>Diff me!</span>
                <MyInput ref="unemployment-reason" name="unemployment-reason" />

}

Fail module works great! Thanks.

I had to define my fact before checking it, otherwise I'd get an undefined variable error.

And I had issues when doing setting the fact with quotes and without spaces.

This worked:

set_fact: flag="failed"

This threw errors:

set_fact: flag = failed 

protected void gvTurnos_RowDataBound(object sender, GridViewRowEventArgs e)
{
    try
    {

        if (e.Row.RowType == DataControlRowType.EmptyDataRow)
        {
            LinkButton btn = (LinkButton)e.Row.FindControl("btnAgregarVacio");
            if (btn != null)
            {
                btn.Visible = rbFiltroEstatusCampus.SelectedValue == "1" ? true : false;

Use Form, not form. The capitalization counts.

How are you? I had the same problem while i was trying connect to MSSQL Server remotely using jdbc (dbeaver on debian).

After a while, i found out that my firewall configuration was not correctly. So maybe it could help you!

Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.

Four exceptions must be configured in Windows Firewall to allow access to SQL Server:

A port exception for TCP Port 1433. In the New Inbound Rule Wizard dialog, use the following information to create a port exception: Select Port Select TCP and specify port 1433 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – TCP 1433" A port exception for UDP Port 1434. Click New Rule again and use the following information to create another port exception: Select Port Select UDP and specify port 1434 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – UDP 1434 A program exception for sqlservr.exe. Click New Rule again and use the following information to create a program exception: Select Program Click Browse to select ‘sqlservr.exe’ at this location: [C:\Program Files\Microsoft SQL Server\MSSQL11.\MSSQL\Binn\sqlservr.exe] where is the name of your SQL instance.

If you use several different versions of python try using virtualenv http://www.virtualenv.org/en/latest/virtualenv.html#installation

With the advantage of pip for each local environment.

Then install a local environment in the current directory by:

virtualenv -p /usr/local/bin/python3.3 ENV --verbose

Note that you specify the path to a python binary you have installed on your system.

Then there are now an local pythonenvironment in that folder. ./ENV

Now there should be ./ENV/pip-3.3

use ./ENV/pip-3.3 freeze to list the local installed libraries.

use ./ENV/pip-3.3 install packagename to install at the local environment.

use ./ENV/python3.3 pythonfile.py to run your python script.

To tackle this with vanilla CSS look for patterns in the ancestors of the h1..h6 elements:

<section class="row">
  <header>
    <h1>AMD RX Series</h1>
    <small>These come in different brands and types</small>
  </header>
</header>

<div class="row">
  <h3>Sapphire RX460 OC 2/4GB</h3>
  <small>Available in 2GB and 4GB models</small>
</div>

If you can spot patterns you may be able to write a selector which targets what you want. Given the above example all h1..h6 elements may be targeted by combining the :first-child and :not pseudo-classes from CSS3, available in all modern browsers, like so:

.row :first-child:not(header) { /* ... */ }

In the future advanced pseudo-class selectors like :has(), and subsequent-sibling combinators (~), will provide even more control as Web standards continue to evolve over time.

Use stored procedures.

And even assuming you would want not to use stored procedures - there is at most 3 commands to be run, not 4. Second getting id is useless, as you can do "INSERT INTO ... RETURNING".

Spring security is a filter based framework, it plants a WALL(HttpFireWall) before your application in terms of proxy filters or spring managed beans. Your request has to pass through multiple filters to reach your API.

Sequence of execution in Spring Security

1. WebAsyncManagerIntegrationFilter Provides integration between the SecurityContext and Spring Web's WebAsyncManager.
   

2. SecurityContextPersistenceFilter This filter will only execute once per request, Populates the SecurityContextHolder with information obtained from the configured SecurityContextRepository prior to the request and stores it back in the repository once the request has completed and clearing the context holder.
   Request is checked for existing session. If new request, SecurityContext will be created else if request has session then existing security-context will be obtained from respository.

3. HeaderWriterFilter Filter implementation to add headers to the current response.

4. LogoutFilter If request url is /logout(for default configuration) or if request url mathces RequestMatcher configured in LogoutConfigurer then

   • clears security context.
   • invalidates the session
   • deletes all the cookies with cookie names configured in LogoutConfigurer
   • Redirects to default logout success url / or logout success url configured or invokes logoutSuccessHandler configured.

5. UsernamePasswordAuthenticationFilter

   • For any request url other than loginProcessingUrl this filter will not process further but filter chain just continues.
   • If requested URL is matches(must be HTTP POST) default /login or matches .loginProcessingUrl() configured in FormLoginConfigurer then UsernamePasswordAuthenticationFilter attempts authentication.
   • default login form parameters are username and password, can be overridden by usernameParameter(String), passwordParameter(String).
   • setting .loginPage() overrides defaults
   • While attempting authentication
     • an Authentication object(UsernamePasswordAuthenticationToken or any implementation of Authentication in case of your custom auth filter) is created.
     • and authenticationManager.authenticate(authToken) will be invoked
       
     • Note that we can configure any number of AuthenticationProvider authenticate method tries all auth providers and checks any of the auth provider supports authToken/authentication object, supporting auth provider will be used for authenticating. and returns Authentication object in case of successful authentication else throws AuthenticationException.
   • If authentication success session will be created and authenticationSuccessHandler will be invoked which redirects to the target url configured(default is /)
   • If authentication failed user becomes un-authenticated user and chain continues.

6. SecurityContextHolderAwareRequestFilter, if you are using it to install a Spring Security aware HttpServletRequestWrapper into your servlet container

7. AnonymousAuthenticationFilter Detects if there is no Authentication object in the SecurityContextHolder, if no authentication object found, creates Authentication object (AnonymousAuthenticationToken) with granted authority ROLE_ANONYMOUS. Here AnonymousAuthenticationToken facilitates identifying un-authenticated users subsequent requests.
   

DEBUG - /app/admin/app-config at position 9 of 12 in additional filter chain; firing Filter: 'AnonymousAuthenticationFilter'
DEBUG - Populated SecurityContextHolder with anonymous token: 'org.springframework.security.authentication.AnonymousAuthenticationToken@aeef7b36: Principal: anonymousUser; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@b364: RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: null; Granted Authorities: ROLE_ANONYMOUS' 

8. ExceptionTranslationFilter, to catch any Spring Security exceptions so that either an HTTP error response can be returned or an appropriate AuthenticationEntryPoint can be launched

9. FilterSecurityInterceptor
   There will be FilterSecurityInterceptor which comes almost last in the filter chain which gets Authentication object from SecurityContext and gets granted authorities list(roles granted) and it will make a decision whether to allow this request to reach the requested resource or not, decision is made by matching with the allowed AntMatchers configured in HttpSecurityConfiguration.

Consider the exceptions 401-UnAuthorized and 403-Forbidden. These decisions will be done at the last in the filter chain

• Un authenticated user trying to access public resource - Allowed
  
• Un authenticated user trying to access secured resource - 401-UnAuthorized
  
• Authenticated user trying to access restricted resource(restricted for his role) - 403-Forbidden
  

Note: User Request flows not only in above mentioned filters, but there are others filters too not shown here.(ConcurrentSessionFilter,RequestCacheAwareFilter,SessionManagementFilter ...)
It will be different when you use your custom auth filter instead of UsernamePasswordAuthenticationFilter.
It will be different if you configure JWT auth filter and omit .formLogin() i.e, UsernamePasswordAuthenticationFilter it will become entirely different case.

From Documentation ordering of filters is given as

• ChannelProcessingFilter
• ConcurrentSessionFilter
• SecurityContextPersistenceFilter
• LogoutFilter
• X509AuthenticationFilter
• AbstractPreAuthenticatedProcessingFilter
• CasAuthenticationFilter
• UsernamePasswordAuthenticationFilter
• ConcurrentSessionFilter
• OpenIDAuthenticationFilter
• DefaultLoginPageGeneratingFilter
• DefaultLogoutPageGeneratingFilter
• ConcurrentSessionFilter
• DigestAuthenticationFilter
• BearerTokenAuthenticationFilter
• BasicAuthenticationFilter
• RequestCacheAwareFilter
• SecurityContextHolderAwareRequestFilter
• JaasApiIntegrationFilter
• RememberMeAuthenticationFilter
• AnonymousAuthenticationFilter
• SessionManagementFilter
• ExceptionTranslationFilter
• FilterSecurityInterceptor
• SwitchUserFilter

Edit: Thanks Marc, read up on the struct vs class issue and you're right, thank you!

I tend to use the following method for doing what you describe, using a static method of JSon.Net:

MyObject deserializedObject = JsonConvert.DeserializeObject<MyObject>(json);

Link: Serializing and Deserializing JSON with Json.NET

For the Objects list, may I suggest using generic lists out made out of your own small class containing attributes and position class. You can use the Point struct in System.Drawing (System.Drawing.Point or System.Drawing.PointF for floating point numbers) for you X and Y.

After object creation it's much easier to get the data you're after vs. the text parsing you're otherwise looking at.

A single liner, using find:

find -type f -exec grep -lm1 "PATTERN" {} \; -a -quit

Try cleaning the project:

1. shift + cmd + k
2. shift + cmd + Alt + k 

Then try to run your project again. Hope this will fix the problem.

So actually, my comment that you should do a console.log(el.nativeElement) should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element.

What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el) in your example, then you'll have access to the nativeElement object and will see a property called innerHTML.

Which will lead to the answer to your original question:

let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element

Update for better approach:

Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.

The best way to manipulate DOM Elements programmatically is using the Renderer:

constructor(private _elemRef: ElementRef, private _renderer: Renderer) { 
    this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}

Edit

Since Renderer is deprecated now, use Renderer2 instead with setProperty

Update:

This question with its answer explained the console.log behavior.

Which means that console.dir(el.nativeElement) would be the more direct way of accessing the DOM Element as an "inspectable" Object in your console for this situation.

Hope this helped.

function GetUserIP(){
  var ret_ip;
  $.ajaxSetup({async: false});
  $.get('http://jsonip.com/', function(r){ 
    ret_ip = r.ip; 
  });
  return ret_ip;
}

If you want to use the IP and assign it to a variable, Try this. Just call GetUserIP()

You can't read individual integers in a single line separately using BufferedReader as you do using Scannerclass. Although, you can do something like this in regard to your query :

import java.io.*;
class Test
{
   public static void main(String args[])throws IOException
    {
       BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
       int t=Integer.parseInt(br.readLine());
       for(int i=0;i<t;i++)
       {
         String str=br.readLine();
         String num[]=br.readLine().split(" ");
         int num1=Integer.parseInt(num[0]);
         int num2=Integer.parseInt(num[1]);
         //rest of your code
       }
    }
}

I hope this will help you.

I increase max memory to start node-chrome with -Xmx3g, and it's work for me

Aggregation vs Composition

Aggregation implies a relationship where the child can exist independently of the parent. For example, Bank and Employee, delete the Bank and the Employee still exist.

whereas Composition implies a relationship where the child cannot exist independent of the parent. Example: Human and heart, heart don’t exist separate to a Human.

Aggregation relation is “has-a” and composition is “part-of” relation.

Composition is a strong Association whereas Aggregation is a weak Association.

I didn’t like any of these answers because none handle floating-point arrays in a linear algebra or vector space sense, where two rows being “equal” means “within some ”. The one answer that has a tolerance threshold, https://stackoverflow.com/a/26867764/500207, took the threshold to be both element-wise and decimal precision, which works for some cases but isn’t as mathematically general as a true vector distance.

Here’s my version:

from scipy.spatial.distance import squareform, pdist

def uniqueRows(arr, thresh=0.0, metric='euclidean'):
    "Returns subset of rows that are unique, in terms of Euclidean distance"
    distances = squareform(pdist(arr, metric=metric))
    idxset = {tuple(np.nonzero(v)[0]) for v in distances <= thresh}
    return arr[[x[0] for x in idxset]]

# With this, unique columns are super-easy:
def uniqueColumns(arr, *args, **kwargs):
    return uniqueRows(arr.T, *args, **kwargs)

The public-domain function above uses scipy.spatial.distance.pdist to find the Euclidean (customizable) distance between each pair of rows. Then it compares each each distance to a threshold to find the rows that are within thresh of each other, and returns just one row from each thresh-cluster.

As hinted, the distance metric needn’t be Euclidean—pdist can compute sundry distances including cityblock (Manhattan-norm) and cosine (the angle between vectors).

If thresh=0 (the default), then rows have to be bit-exact to be considered “unique”. Other good values for thresh use scaled machine-precision, i.e., thresh=np.spacing(1)*1e3.

From here:

"You can also refer to the properties of the data object via that object, instead of accessing them as variables." Meaning that for OP's case this will work (with a significantly smaller change than other possible solutions):

<% if (obj.date) { %><span class="date"><%= date %></span><% }  %>

It is too late but helps someone, I'm using node version v7.9.0 and express version 4.15.0

if your directory structure is something like this:

your-project
   uploads
   package.json
   server.js

server.js code:

var express         = require('express');
var app             = express();
app.use(express.static(__dirname + '/uploads'));// you can access image 
 //using this url: http://localhost:7000/abc.jpg
//make sure `abc.jpg` is present in `uploads` dir.

//Or you can change the directory for hiding real directory name:

`app.use('/images', express.static(__dirname+'/uploads/'));// you can access image using this url: http://localhost:7000/images/abc.jpg


app.listen(7000);

I have passed through that error today and did everything described above but didn't work for me. So I decided to view the core problem and logged onto the MySQL root folder in Windows 7 and did this solution:

1. Go to folder:

   C:\AppServ\MySQL
   

2. Right click and Run as Administrator these files:

   mysql_servicefix.bat
   
   mysql_serviceinstall.bat
   
   mysql_servicestart.bat
   

Then close the entire explorer window and reopen it or clear cache then login to phpMyAdmin again.

Here's an explanation I wrote recently to help with the void of information on this attribute. http://www.marklio.com/marklio/PermaLink,guid,ecc34c3c-be44-4422-86b7-900900e451f9.aspx (Internet Archive Wayback Machine link)

To quote the most relevant bits:

[Installing .NET] v4 is “non-impactful”. It should not change the behavior of existing components when installed.

The useLegacyV2RuntimeActivationPolicy attribute basically lets you say, “I have some dependencies on the legacy shim APIs. Please make them work the way they used to with respect to the chosen runtime.”

Why don’t we make this the default behavior? You might argue that this behavior is more compatible, and makes porting code from previous versions much easier. If you’ll recall, this can’t be the default behavior because it would make installation of v4 impactful, which can break existing apps installed on your machine.

The full post explains this in more detail. At RTM, the MSDN docs on this should be better.

To find the fastest way to read a file line by line you will have to do some benchmarking. I have done some small tests on my computer but you cannot expect that my results apply to your environment.

Using StreamReader.ReadLine

This is basically your method. For some reason you set the buffer size to the smallest possible value (128). Increasing this will in general increase performance. The default size is 1,024 and other good choices are 512 (the sector size in Windows) or 4,096 (the cluster size in NTFS). You will have to run a benchmark to determine an optimal buffer size. A bigger buffer is - if not faster - at least not slower than a smaller buffer.

const Int32 BufferSize = 128;
using (var fileStream = File.OpenRead(fileName))
  using (var streamReader = new StreamReader(fileStream, Encoding.UTF8, true, BufferSize)) {
    String line;
    while ((line = streamReader.ReadLine()) != null)
      // Process line
  }

The FileStream constructor allows you to specify FileOptions. For example, if you are reading a large file sequentially from beginning to end, you may benefit from FileOptions.SequentialScan. Again, benchmarking is the best thing you can do.

Using File.ReadLines

This is very much like your own solution except that it is implemented using a StreamReader with a fixed buffer size of 1,024. On my computer this results in slightly better performance compared to your code with the buffer size of 128. However, you can get the same performance increase by using a larger buffer size. This method is implemented using an iterator block and does not consume memory for all lines.

var lines = File.ReadLines(fileName);
foreach (var line in lines)
  // Process line

Using File.ReadAllLines

This is very much like the previous method except that this method grows a list of strings used to create the returned array of lines so the memory requirements are higher. However, it returns String[] and not an IEnumerable<String> allowing you to randomly access the lines.

var lines = File.ReadAllLines(fileName);
for (var i = 0; i < lines.Length; i += 1) {
  var line = lines[i];
  // Process line
}

Using String.Split

This method is considerably slower, at least on big files (tested on a 511 KB file), probably due to how String.Split is implemented. It also allocates an array for all the lines increasing the memory required compared to your solution.

using (var streamReader = File.OpenText(fileName)) {
  var lines = streamReader.ReadToEnd().Split("\r\n".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
  foreach (var line in lines)
    // Process line
}

My suggestion is to use File.ReadLines because it is clean and efficient. If you require special sharing options (for example you use FileShare.ReadWrite), you can use your own code but you should increase the buffer size.

I've found a better way how to manage JS packages in my project with NPM Gulp/Grunt task runners. I don't like the idea to have a NPM with another layer of javascript library to handle the "automation", and my number one requirement is to simple run the npm update without any other worries about to if I need to run gulp stuff, if it successfully copied everything and vice versa.

The NPM way:

• The JS minifier is already bundled in the ASP.net core, look for bundleconfig.json so this is not an issue for me (not compiling something custom)
• The good thing about NPM is that is have a good file structure so I can always find the pre-compiled/minified versions of the dependencies under the node_modules/module/dist
• I'm using an NPM node_modules/.hooks/{eventname} script which is handling the copy/update/delete of the Project/wwwroot/lib/module/dist/.js files, you can find the documentation here https://docs.npmjs.com/misc/scripts (I'll update the script that I'm using to git once it'll be more polished) I don't need additional task runners (.js tools which I don't like) what keeps my project clean and simple.

The python way:

https://pypi.python.org/pyp... but in this case you need to maintain the sources manually

This will be different for each OS, based on the information at https://code.visualstudio.com/docs/customization/keybindings

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.

Split Function Works Great when you are getting One String containing multiple values but when you are passing Multiple values you need to do something like this....

you can also get the line if there are other characters before token

items=re.findall("^.*token.*$",s,re.MULTILINE)

The above works like grep token on unix and keyword 'in' or .contains in python and C#

As you are not trying to move the files around in the tree, you should be able to just checkout the directory:

git checkout master -- dirname

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

Just a note for php developers (I lack the necessary stackoverflow points to post this as a comment) ... the automagic (and silent) conversion to TINYINT means that php retrieves a value from a "BOOLEAN" column as a "0" or "1", not the expected (by me) true/false.

A developer who is looking at the SQL used to create a table and sees something like: "some_boolean BOOLEAN NOT NULL DEFAULT FALSE," might reasonably expect to see true/false results when a row containing that column is retrieved. Instead (at least in my version of PHP), the result will be "0" or "1" (yes, a string "0" or string "1", not an int 0/1, thank you php).

It's a nit, but enough to cause unit tests to fail.

I have successfully styled my Bootstrap navbar using the following CSS. Also you didn't define any font in your CSS so that's why the font isn't changing. The site for which this CSS is used can be found here.

.navbar-default .navbar-nav > li > a:hover, .navbar-default .navbar-nav > li > a:focus {
    color: #000; /*Sets the text hover color on navbar*/
}

.navbar-default .navbar-nav > .active > a, .navbar-default .navbar-nav > .active >
        a:hover, .navbar-default .navbar-nav > .active > a:focus {
    color: white; /*BACKGROUND color for active*/
    background-color: #030033;
}

.navbar-default {
    background-color: #0f006f;
    border-color: #030033;
}

.dropdown-menu > li > a:hover,
.dropdown-menu > li > a:focus {
    color: #262626;
    text-decoration: none;
    background-color: #66CCFF; /*change color of links in drop down here*/
}

.nav > li > a:hover,
.nav > li > a:focus {
    text-decoration: none;
    background-color: silver; /*Change rollover cell color here*/
}

.navbar-default .navbar-nav > li > a {
    color: white; /*Change active text color here*/
}

Sometimes when your table has a similar name to the database name you should use back tick. so instead of:

INSERT INTO books.book(field1, field2) VALUES ('value1', 'value2');

You should have this:

INSERT INTO `books`.`book`(`field1`, `field2`) VALUES ('value1', 'value2');

Method 1

The problem with your code is that you are selecting the .remode_hover that is a descendant of .remode_selected. So the first part of getting your code to work correctly is by removing that space

.reMode_selected.reMode_hover:hover

Then, in order to get the style to not work, you have to override the style set by the :hover. In other words, you need to counter the background-color property. So the final code will be

.reMode_selected.reMode_hover:hover {
  background-color:inherit;
}
.reMode_hover:hover {
  background-color: #f0ac00;
}

Fiddle

Method 2

An alternative method would be to use :not(), as stated by others. This will return any element that doesn't have the class or property stated inside the parenthesis. In this case, you would put .remode_selected in there. This will target all elements that don't have a class of .remode_selected

Fiddle

However, I would not recommend this method, because of the fact that it was introduced in CSS3, so browser support is not ideal.

Method 3

A third method would be to use jQuery. You can target the .not() selector, which would be similar to using :not() in CSS, but with much better browser support

Fiddle

x = y = 5 is equivalent to x = (y = 5), because the assignment operators "group" right to left, which works. Meaning: assign 5 to y, leaving the number 5; and then assign that 5 to x.

This is not the same as (x = y) = 5, which doesn't work! Meaning: assign the value of y to x, leaving the value of y; and then assign 5 to, umm..., what exactly?

When you mix the different kinds of assignment operators, <- binds tighter than =. So x = y <- 5 is interpreted as x = (y <- 5), which is the case that makes sense.

Unfortunately, x <- y = 5 is interpreted as (x <- y) = 5, which is the case that doesn't work!

See ?Syntax and ?assignOps for the precedence (binding) and grouping rules.

Indeed a one-hot encoder will work just fine here, convert any string and numerical categorical variables you want into 1's and 0's this way and random forest should not complain.

For 2 use cases:

1. I only want n overall results, not n results per file, the grep -m 2 is per file max occurrence.
2. I often use git grep which doesn't take -m

A good alternative in these scenarios is grep | sed 2q to grep first 2 occurrences across all files. sed documentation: https://www.gnu.org/software/sed/manual/sed.html

Does c# have its own version of the java "synchronized" keyword?

No. In C#, you explicitly lock resources that you want to work on synchronously across asynchronous threads. lock opens a block; it doesn't work on method level.

However, the underlying mechanism is similar since lock works by invoking Monitor.Enter (and subsequently Monitor.Exit) on the runtime. Java works the same way, according to the Sun documentation.

I encountered this error when using Travis CI to deploy content, which involved pushing edits to a repository.

I eventually solved the issue by updating the GitHub personal access token associated with the Travis account with the public_repo scope access permission:

SELECT @variable1 = col1, @variable2 = col2
FROM table1

As @huyz mention sometimes desired behavior is using case-insensitive searches but case-sensitive substitutions. My solution for that:

nnoremap / /\c
nnoremap ? ?\c

With that always when you hit / or ? it will add \c for case-insensitive search.

To post files as from byte arrays:

private static string UploadFilesToRemoteUrl(string url, IList<byte[]> files, NameValueCollection nvc) {

        string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");

        var request = (HttpWebRequest) WebRequest.Create(url);
        request.ContentType = "multipart/form-data; boundary=" + boundary;
        request.Method = "POST";
        request.KeepAlive = true;
        var postQueue = new ByteArrayCustomQueue();

        var formdataTemplate = "\r\n--" + boundary + "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";

        foreach (string key in nvc.Keys) {
            var formitem = string.Format(formdataTemplate, key, nvc[key]);
            var formitembytes = Encoding.UTF8.GetBytes(formitem);
            postQueue.Write(formitembytes);
        }

        var headerTemplate = "\r\n--" + boundary + "\r\n" +
            "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n" +

        var i = 0;
        foreach (var file in files) {
            var header = string.Format(headerTemplate, "file" + i, "file" + i + ".zip");
            var headerbytes = Encoding.UTF8.GetBytes(header);
            postQueue.Write(headerbytes);
            postQueue.Write(file);
            i++;
        }

        postQueue.Write(Encoding.UTF8.GetBytes("\r\n--" + boundary + "--"));

        request.ContentLength = postQueue.Length;

        using (var requestStream = request.GetRequestStream()) {
            postQueue.CopyToStream(requestStream);
            requestStream.Close();
        }

        var webResponse2 = request.GetResponse();

            webResponse2.Close();
            return res;

Try these simple steps:

ObjectMapper mapper = new ObjectMapper();
String newJsonData = mapper.writeValueAsString(cartList);
return newJsonData;
ObjectMapper() is com.fasterxml.jackson.databind.ObjectMapper.ObjectMapper();

For a non-recursive delete (using du and awk):

rm `du * | awk '$1 == "0" {print $2}'`

you can also use this code in your style.xml file so you don't need to write anything else in your activity.java

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>

    <item name="android:windowExitAnimation">@android:anim/fade_out</item>
</style>

Is it possible that you can avoid using wsdl2java? You can straight away use CXF FrontEnd APIs to invoke your SOAP Webservice. The only catch is that you need to create your SEI and VOs on your client end. Here is a sample code.

package com.aranin.weblog4j.client;

import com.aranin.weblog4j.services.BookShelfService;
import com.aranin.weblog4j.vo.BookVO;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class DemoClient {
    public static void main(String[] args){
        String serviceUrl = "http://localhost:8080/weblog4jdemo/bookshelfservice";
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(BookShelfService.class);
        factory.setAddress(serviceUrl);
        BookShelfService bookService = (BookShelfService) factory.create();

        //insert book
        BookVO bookVO = new BookVO();
        bookVO.setAuthor("Issac Asimov");
        bookVO.setBookName("Foundation and Earth");

        String result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        bookVO = new BookVO();
        bookVO.setAuthor("Issac Asimov");
        bookVO.setBookName("Foundation and Empire");

        result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        bookVO = new BookVO();
        bookVO.setAuthor("Arthur C Clarke");
        bookVO.setBookName("Rama Revealed");

        result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        //retrieve book

        bookVO = bookService.getBook("Foundation and Earth");

        System.out.println("book name : " + bookVO.getBookName());
        System.out.println("book author : " + bookVO.getAuthor());

    }
}

If you want to change theme of an already existing activity, call recreate() after setTheme().

Note: don't call recreate if you change theme in onCreate(), to avoid infinite loop.

I solved this problem by using @ResponseBody like below:

@RequestMapping(value = "/resturl", method = RequestMethod.GET, produces = {"application/json"})
    @ResponseStatus(HttpStatus.OK)
    @Transactional(value = "jpaTransactionManager")
    public @ResponseBody List<DomainObject> findByResourceID(@PathParam("resourceID") String resourceID) {

If you are using visual studio code:

1. Open terminal
2. Run the command: Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
3. Then run the command protractor conf.js

This is related to protractor test script execution related and I faced the same issue and it was resolved like this.

Try with this solution: http://phppot.com/php/sorting-mysql-row-order-using-jquery/ where new order is saved in some HMTL element. Then you submit the form with this data to some PHP script, and iterate trough it with for loop.

Note: I had to add another db field of type INT(11) which is updated(timestamp'ed) on each iteration - it serves for script to know which row is recenty updated, or else you end up with scrambled results.

try something like this :

    DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
    Document dDoc = builder.parse("d://utf8test.xml");

    XPath xPath = XPathFactory.newInstance().newXPath();
    NodeList nodes = (NodeList) xPath.evaluate("//xml/ep/source/@type", dDoc, XPathConstants.NODESET);
    for (int i = 0; i < nodes.getLength(); i++) {
        Node node = nodes.item(i);
        System.out.println(node.getTextContent());
    }

please note the changes :

• we ask for a nodeset (XPathConstants.NODESET) and not only for a single node.
• the xpath is now //xml/ep/source/@type and not //xml/source/@type/text()

PS: can you add the tag java to your question ? thanks.

If I can add my $0.02, I prefer using PascalCase as enum values in C.

In C, they are basically global, and PEER_CONNECTED gets really tiring as opposed to PeerConnected.

Breath of fresh air.

Literally, it makes me breathe easier.

In Java, it is possible to use raw enum names as long as you static import them from another class.

import static pkg.EnumClass.*;

Now, you can use the unqualified names, that you qualified in a different way already.

I am currently (thinking) about porting some C code to Java and currently 'torn' between choosing Java convention (which is more verbose, more lengthy, and more ugly) and my C style.

PeerConnected would become PeerState.CONNECTED except in switch statements, where it is CONNECTED.

Now there is much to say for the latter convention and it does look nice but certain "idiomatic phrases" such as if (s == PeerAvailable) become like if (s == PeerState.AVAILABLE) and nostalgically, this is a loss of meaning to me.

I think I still prefer the Java style because of clarity but I have a hard time looking at the screaming code.

Now I realize PascalCase is already widely used in Java but very confusing it would not really be, just a tad out of place.

Generally i live this situation when parent of my object is hidden. for example when the html is like this:

    <div class="div-parent" style="display:none">
        <div class="div-child" style="display:block">
        </div>
    </div>

if you ask if child is visible like:

    $(".div-child").is(":visible");

it will return false because its parent is not visible so that div wont be visible, also.

I think you both are right. The later answer works fine but its like setting a global option so you have to do the following:

    $.ajaxSetup({
        async: false
    });

    //ajax call here

    $.ajaxSetup({
        async: true
    });

Building on the answer by @JoelCoehoorn, my approach is to leave all my PRINT statements in place, and simply follow them with the RAISERROR statement to cause the flush.

For example:

PRINT 'MyVariableName: ' + @MyVariableName
RAISERROR(N'', 0, 1) WITH NOWAIT

The advantage of this approach is that the PRINT statements can concatenate strings, whereas the RAISERROR cannot. (So either way you have the same number of lines of code, as you'd have to declare and set a variable to use in RAISERROR).

If, like me, you use AutoHotKey or SSMSBoost or an equivalent tool, you can easily set up a shortcut such as "]flush" to enter the RAISERROR line for you. This saves you time if it is the same line of code every time, i.e. does not need to be customised to hold specific text or a variable.

A related question has been asked before: What is “above-the-fold content” in Google Pagespeed?

Firstly you have to notice that this is all about 'mobile pages'.
So when I interpreted your question and screenshot correctly, then this is not for your site!

On the contrary - doing some of the things advised by Google in their guidelines will things make worse than better for 'normal' websites.
And not everything that comes from Google is the "holy grail" just because it comes from Google. And they themselves are not a good role model if you have a look at their HTML markup.

The best advice I could give you is:

• Set width and height on replaced elements in your CSS, so that the browser can layout the elements and doesn't have to wait for the replaced content!

Additionally why do you use different CSS files, rather than just one?
The additional request is worse than the small amount of data volume. And after the first request the CSS file is cached anyway.

The things one should always take care of are:

• reduce the number of requests as much as possible
• keep your overall page weight as low as possible

And don't puzzle your brain about how to get 100% of Google's PageSpeed Insights tool ...! ;-)

Addition 1: Here is the page on which Google shows us, what they recommend for Optimize CSS Delivery.

As said before, I don't think that this is neither realistic nor that it makes sense for a "normal" website! Because mainly when you have a responsive web design it is most certain that you use media queries and other layout styles. So if you are not gonna load your CSS first and in a blocking manner you'll get a FOUT (Flash Of Unstyled Text). I really do not believe that this is "better" than at least some more milliseconds to render the page!

Imho Google is starting a new "hype" (when I have a look at all the question about it here on Stackoverflow) ...!

For an actual HQL query:

FROM Users WHERE Name IS NULL

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

Here's a script that will use the Google API to acquire the users postal code and populate an input field.

function postalCodeLookup(input) {
    var head= document.getElementsByTagName('head')[0],
        script= document.createElement('script');
    script.src= '//maps.googleapis.com/maps/api/js?sensor=false';
    head.appendChild(script);
    script.onload = function() {
        if (navigator.geolocation) {
            var a = input,
                fallback = setTimeout(function () {
                    fail('10 seconds expired');
                }, 10000);

            navigator.geolocation.getCurrentPosition(function (pos) {
                clearTimeout(fallback);
                var point = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
                new google.maps.Geocoder().geocode({'latLng': point}, function (res, status) {
                    if (status == google.maps.GeocoderStatus.OK && typeof res[0] !== 'undefined') {
                        var zip = res[0].formatted_address.match(/,\s\w{2}\s(\d{5})/);
                        if (zip) {
                            a.value = zip[1];
                        } else fail('Unable to look-up postal code');
                    } else {
                        fail('Unable to look-up geolocation');
                    }
                });
            }, function (err) {
                fail(err.message);
            });
        } else {
            alert('Unable to find your location.');
        }
        function fail(err) {
            console.log('err', err);
            a.value('Try Again.');
        }
    };
}

You can adjust accordingly to acquire different information. For more info, check out the Google Maps API documentation.

JSON_UNESCAPED_UNICODE is available on PHP Version 5.4 or later.
The following code is for Version 5.3.

UPDATED

• html_entity_decode is a bit more efficient than pack + mb_convert_encoding.
• (*SKIP)(*FAIL) skips backslashes itself and specified characters by JSON_HEX_* flags.

function raw_json_encode($input, $flags = 0) {
    $fails = implode('|', array_filter(array(
        '\\\\',
        $flags & JSON_HEX_TAG ? 'u003[CE]' : '',
        $flags & JSON_HEX_AMP ? 'u0026' : '',
        $flags & JSON_HEX_APOS ? 'u0027' : '',
        $flags & JSON_HEX_QUOT ? 'u0022' : '',
    )));
    $pattern = "/\\\\(?:(?:$fails)(*SKIP)(*FAIL)|u([0-9a-fA-F]{4}))/";
    $callback = function ($m) {
        return html_entity_decode("&#x$m[1];", ENT_QUOTES, 'UTF-8');
    };
    return preg_replace_callback($pattern, $callback, json_encode($input, $flags));
}

you can use style

   <td  colspan="2">
     <div style="float:left; width:80px"><asp:Label ID="Label6" runat="server" Text="Label"></asp:Label></div>

    <div style="float: right; width:100px">

There are differences with some exceptions, e.g. KeyboardInterrupt.

Reading PEP8:

A bare except: clause will catch SystemExit and KeyboardInterrupt exceptions, making it harder to interrupt a program with Control-C, and can disguise other problems. If you want to catch all exceptions that signal program errors, use except Exception: (bare except is equivalent to except BaseException:).

It looks like you're using ngModel on the same form field as formControlName. Support for using the ngModel input property and ngModelChange event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7

The answer lies within the Java Documentation's Tutorial for Writing/Saving an Image.

The Image I/O class provides the following method for saving an image:

static boolean ImageIO.write(RenderedImage im, String formatName, File output)  throws IOException

The tutorial explains that

The BufferedImage class implements the RenderedImage interface.

so it's able to be used in the method.

For example,

try {
    BufferedImage bi = getMyImage();  // retrieve image
    File outputfile = new File("saved.png");
    ImageIO.write(bi, "png", outputfile);
} catch (IOException e) {
    // handle exception
}

It's important to surround the write call with a try block because, as per the API, the method throws an IOException "if an error occurs during writing"

Also explained are the method's objective, parameters, returns, and throws, in more detail:

Writes an image using an arbitrary ImageWriter that supports the given format to a File. If there is already a File present, its contents are discarded.

Parameters:

im - a RenderedImage to be written.

formatName - a String containg the informal name of the format.

output - a File to be written to.

Returns:

false if no appropriate writer is found.

Throws:

IllegalArgumentException - if any parameter is null.

IOException - if an error occurs during writing.

However, formatName may still seem rather vague and ambiguous; the tutorial clears it up a bit:

The ImageIO.write method calls the code that implements PNG writing a “PNG writer plug-in”. The term plug-in is used since Image I/O is extensible and can support a wide range of formats.

But the following standard image format plugins : JPEG, PNG, GIF, BMP and WBMP are always be present.

For most applications it is sufficient to use one of these standard plugins. They have the advantage of being readily available.

There are, however, additional formats you can use:

The Image I/O class provides a way to plug in support for additional formats which can be used, and many such plug-ins exist. If you are interested in what file formats are available to load or save in your system, you may use the getReaderFormatNames and getWriterFormatNames methods of the ImageIO class. These methods return an array of strings listing all of the formats supported in this JRE.

String writerNames[] = ImageIO.getWriterFormatNames();

The returned array of names will include any additional plug-ins that are installed and any of these names may be used as a format name to select an image writer.

For a full and practical example, one can refer to Oracle's SaveImage.java example.

The cli command I've used with python for this is:

cat myfile.json | python -mjson.tool

You should be able to find more info here:

http://docs.python.org/library/json.html

This won't work if the data is not sequential (1 2 3 4 but 5 7 3 1 5) as in that case you can't sort it.

Here is how I solve that issue for me:

Column A initial data that needs to contain 5 rows between each number - 5 4 6 8 9

Column B - 1 2 3 4 5 (final number represents the number of empty rows that you need to be between numbers in column A) copy-paste 1-5 in column B as long as you have numbers in column A.

Jump to D column, in D1 type 1. In D2 type this formula - =IF(B2=1,1+D1,D1) Drag it to the same length as column B.

Back to Column C - at C1 cell type this formula - =IF(B1=1,INDIRECT("a"&(D1)),""). Drag it down and we done. Now in column C we have same sequence of numbers as in column A distributed separately by 4 rows.

We use something like this and very useful for me .

In Java 8 that parameter is commonly used to print a warning message like this one:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

The reason why you get this message in Java 8 is because Permgen has been replaced by Metaspace to address some of PermGen's drawbacks (as you were able to see for yourself, one of those drawbacks is that it had a fixed size).

FYI: an article on Metaspace: http://java-latte.blogspot.in/2014/03/metaspace-in-java-8.html

Here's an example:

public class Main {

    public static void main(String[] args) {

        double val1 = 100;
        double val2 = 10;
        char operation = 'd';
        double result = 0;

        switch (operation) {

            case 'a':
                result = val1 + val2; break;

            case 's':
                result = val1 - val2; break;
            case 'd':
                if (val2 != 0)
                    result = val1 / val2; break;
            case 'm':
                result = val1 * val2; break;

            default: System.out.println("Not a defined operation");


        }

        System.out.println(result);
    }
}

Check out new Tool bar on support library class in Lollipop update you can design actionbar by adding toolbar in your layout

add these items in your app theme

 <item name="android:windowNoTitle">true</item>
 <item name="windowActionBar">false</item>

Create your toolbar in a layout and include your textview in center design your toolbar

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/acbarcolor">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/toolbar_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:text="@string/app_name"
            android:textColor="#ffffff"
            android:textStyle="bold" />

    </RelativeLayout>

</android.support.v7.widget.Toolbar>

add your action bar as tool bar

toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

please ensure that you need to include toolbar on your resource file like this

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    android:orientation="vertical"
    android:layout_height="match_parent"
    android:layout_width="match_parent"

I ended creating my own functions:

@Component({
    selector: 'cookie-consent',
    template: cookieconsent_html,
    styles: [cookieconsent_css]
})
export class CookieConsent {
    private isConsented: boolean = false;

    constructor() {
        this.isConsented = this.getCookie(COOKIE_CONSENT) === '1';
    }

    private getCookie(name: string) {
        let ca: Array<string> = document.cookie.split(';');
        let caLen: number = ca.length;
        let cookieName = `${name}=`;
        let c: string;

        for (let i: number = 0; i < caLen; i += 1) {
            c = ca[i].replace(/^\s+/g, '');
            if (c.indexOf(cookieName) == 0) {
                return c.substring(cookieName.length, c.length);
            }
        }
        return '';
    }

    private deleteCookie(name) {
        this.setCookie(name, '', -1);
    }

    private setCookie(name: string, value: string, expireDays: number, path: string = '') {
        let d:Date = new Date();
        d.setTime(d.getTime() + expireDays * 24 * 60 * 60 * 1000);
        let expires:string = `expires=${d.toUTCString()}`;
        let cpath:string = path ? `; path=${path}` : '';
        document.cookie = `${name}=${value}; ${expires}${cpath}`;
    }

    private consent(isConsent: boolean, e: any) {
        if (!isConsent) {
            return this.isConsented;
        } else if (isConsent) {
            this.setCookie(COOKIE_CONSENT, '1', COOKIE_CONSENT_EXPIRE_DAYS);
            this.isConsented = true;
            e.preventDefault();
        }
    }
}

Instead of using a dot, like: 1.2, try to input like this: 1,2.

For those using Winginx (nginx based instead of Apache based), I fixed it with these 4 steps:

1. On the Tools menu hit the Winginx PHP5 Config (never mind the 5 in the name...):

   

2. Select the PHP version you want the php.ini to change:

   

3. On the PHP Extensions tab select the php_openssl extension and hit the Save button:

   

4. restart the appropriate PHP service through the taskbar (Stop and Start):

   

This will try the subdir if the file doesn't exist in the root. Needed this as I moved a basic .html website that expects to be ran at the root level and pushed it to a subdir. Only works if all files are flat (no .htaccess trickery in the subdir possible). Useful for linked things like css and js files.

# Internal Redirect to subdir if file is found there.
RewriteEngine on
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI} !-s
RewriteCond %{DOCUMENT_ROOT}/subdir/%{REQUEST_URI} -s
RewriteRule ^(.*)$ /subdir/$1 [L]

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

Use SequenceEqual to check for sequence equality because Equals method checks for reference equality.

var a = ints1.SequenceEqual(ints2);

Or if you don't care about elements order use Enumerable.All method:

var a = ints1.All(ints2.Contains);

The second version also requires another check for Count because it would return true even if ints2 contains more elements than ints1. So the more correct version would be something like this:

var a = ints1.All(ints2.Contains) && ints1.Count == ints2.Count;

In order to check inequality just reverse the result of All method:

var a = !ints1.All(ints2.Contains)

First, attempt to pull from the same refspec that you are trying to push to.

If this does not work, you can force a git push by using git push -f <repo> <refspec>, but use caution: this method can cause references to be deleted on the remote repository.

Two suggestions:

1. Use std::deque instead of std::vector for better performance in your specific case and use the method std::deque::pop_front().
2. Rethink (I mean: delete) the & in std::vector<ScanRule>& topPriorityRules;

Start your script with the following line. The script will first run and then you will get the python command prompt. At this point all variables and functions will be available for interactive use and invocations.

#!/usr/bin/env python -i

You can use Programmatic Navigation.In order to go back, you use this:

router.go(n) 

Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:

<a @click="$router.go(-1)">back</a>

You can use the RTrim function to trim all whitespace from the right. Use LTrim to trim all whitespace from the left. For example

UPDATE Table SET Name = RTrim(Name)

Or for both left and right trim

UPDATE Table SET Name = LTrim(RTrim(Name))

I'm not really too clear what you are asking, but using the -f command line option just specifies a file - it doesn't tell make to change directories. If you want to do the work in another directory, you need to cd to the directory:

clean:
    cd gtest-1.4.0 && $(MAKE) clean

Note that each line in Makefile runs in a separate shell, so there is no need to change the directory back.

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`
  

Use ==:

pip install django_modeltranslation==0.4.0-beta2

You don't really need the directive, can achieve it by using the ng-init and ng-checked. below demo link shows how to set the initial value for checkbox in angularjs.

demo link:

<form>
    <div>
      Released<input type="checkbox" ng-model="Released" ng-bind-html="ACR.Released" ng-true-value="true" ng-false-value="false" ng-init='Released=true' ng-checked='true' /> 
      Inactivated<input type="checkbox" ng-model="Inactivated" ng-bind-html="Inactivated" ng-true-value="true" ng-false-value="false" ng-init='Inactivated=false' ng-checked='false' /> 
      Title Changed<input type="checkbox" ng-model="Title" ng-bind-html="Title" ng-true-value="true" ng-false-value="false" ng-init='Title=false' ng-checked='false' />
    </div>
    <br/>
    <div>Released value is  <b>{{Released}}</b></div>
    <br/>
    <div>Inactivated  value is  <b>{{Inactivated}}</b></div>
    <br/>
    <div>Title  value is  <b>{{Title}}</b></div>
    <br/>
  </form>

// Code goes here

  var app = angular.module("myApp", []);
        app.controller("myCtrl", function ($scope) {

         });    

I'm new to node.js (about 2 weeks), but I've just created a module that recursively reports to the console the contents of an object. It will list all or search for a specific item and then drill down by a given depth if need be.

Perhaps you can customize this to fit your needs. Keep It Simple! Why complicate?...

'use strict';

//console.log("START: AFutils");

// Recusive console output report of an Object
// Use this as AFutils.reportObject(req, "", 1, 3); // To list all items in req object by 3 levels
// Use this as AFutils.reportObject(req, "headers", 1, 10); // To find "headers" item and then list by 10 levels
// yes, I'm OLD School!  I like to see the scope start AND end!!!  :-P
exports.reportObject = function(obj, key, level, deep) 
{
    if (!obj)
    { 
        return;
    }

    var nextLevel = level + 1;

    var keys, typer, prop;
    if(key != "")
    {   // requested field
        keys = key.split(']').join('').split('[');
    }
    else
    {   // do for all
        keys = Object.keys(obj);
    }
    var len = keys.length;
    var add = "";
    for(var j = 1; j < level; j++)
    {
        // I would normally do {add = add.substr(0, level)} of a precreated multi-tab [add] string here, but Sublime keeps replacing with spaces, even with the ["translate_tabs_to_spaces": false] setting!!! (angry)
        add += "\t";
    }

    for (var i = 0; i < len; i++) 
    {
        prop = obj[keys[i]];
        if(!prop)
        {
            // Don't show / waste of space in console window...
            //console.log(add + level + ": UNDEFINED [" + keys[i] + "]");
        }
        else
        {
            typer = typeof(prop);
            if(typer == "function")
            {
                // Don't bother showing fundtion code...
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "}");
            }
            else
            if(typer == "object")
            {
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "}");
                if(nextLevel <= deep)
                {
                    // drop the key search mechanism if first level item has been found...
                    this.reportObject(prop, "", nextLevel, deep); // Recurse into
                }
            }
            else
            {
                // Basic report
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "} = " + prop + ".");
            }
        }
    }
    return ;
};

//console.log("END: AFutils");

The documentation (or The Definitive Guide) says, that you can also use the next query to delete all indices:

curl -XDELETE 'http://localhost:9200/*'

And there's an important note:

For some, the ability to delete all your data with a single command is a very scary prospect. If you want to eliminate the possibility of an accidental mass-deletion, you can set the following to true in your elasticsearch.yml:

action.destructive_requires_name: true

 $.ajax({
         type:'POST',
         url: 'ajaxRequest.php',
         data:{
         userEmail : userEmail
         },
         success:function(data){
         if(data == "error"){
                $('#ShowError').show().text("Email dosen't Match ");
                $('#ShowSuccess').hide();
               }
               else{
                 $('#ShowSuccess').show().text(data);
                }
              }
            });

Updated 10-second countdown using Hooks (a new feature proposal that lets you use state and other React features without writing a class. They’re currently in React v16.7.0-alpha).

import React, { useState, useEffect } from 'react';
import ReactDOM from 'react-dom';

const Clock = () => {
    const [currentCount, setCount] = useState(10);
    const timer = () => setCount(currentCount - 1);

    useEffect(
        () => {
            if (currentCount <= 0) {
                return;
            }
            const id = setInterval(timer, 1000);
            return () => clearInterval(id);
        },

There is a special security expression in spring security:

hasAnyRole(list of roles) - true if the user has been granted any of the roles specified (given as a comma-separated list of strings).

I have never used it but I think it is exactly what you are looking for.

Example usage:

<security:authorize access="hasAnyRole('ADMIN', 'DEVELOPER')">
    ...
</security:authorize>

Here is a link to the reference documentation where the standard spring security expressions are described. Also, here is a discussion where I described how to create custom expression if you need it.

use

=VLOOKUP(D4,F4:G9,2)

with the range F4:G9:

0   0.1
1   0.15
5   0.2
15  0.3
30  1
100 1.3

and D4 being the value in question, e.g. 18.75 -> result: 0.3

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

No, but since C++11 there is [u]int8_t.

Although M-x eval-buffer will work you may run into problems with toggles and other similar things. A better approach might be to "mark" or highlight whats new in your .emacs (or even scratch buffer if your just messing around) and then M-x eval-region. Hope this helps.

Using @Saikh's answer above, the 2nd option, you can add a space between the time itself and the AM or PM.

REVERSE(LEFT(REVERSE(CONVERT(VARCHAR(20),CONVERT(TIME,myDateTime),100)),2) + ' ' + SUBSTRING(REVERSE(CONVERT(VARCHAR(20),CONVERT(TIME,myDateTime),100)),3,20)) AS [Time],

Messy I know, but it's the solution I chose. Strange that the CONVERT() doesn't add that space automatically. SQL Server 2008 R2

In NASM syntax:

mov eax, var       == lea eax, [var]   ; i.e. mov r32, imm32
lea eax, [var+16]  == mov eax, var+16
lea eax, [eax*4]   == shl eax, 2        ; but without setting flags

In MASM syntax, use OFFSET var to get a mov-immediate instead of a load.

One can use assign method of DataFrame:

df= (pd.DataFrame({'Year': ['2014', '2015'], 'quarter': ['q1', 'q2']}).
  assign(period=lambda x: x.Year+x.quarter ))

For Xamarin.iOS (C#):

UIButton messagesButton = new UIButton(UIButtonType.Custom);
UIImage icon = UIImage.FromBundle("Images/icon.png");
messagesButton.SetImage(icon.ImageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), UIControlState.Normal);
messagesButton.TintColor = UIColor.White;
messagesButton.Frame = new RectangleF(0, 0, 25, 25);

You can get the actual height of called layout with this code:

public int getLayoutSize() {
// Get the layout id
    final LinearLayout root = (LinearLayout) findViewById(R.id.mainroot);
    final AtomicInteger layoutHeight = new AtomicInteger();

    root.post(new Runnable() { 
    public void run() { 
        Rect rect = new Rect(); 
        Window win = getWindow();  // Get the Window
                win.getDecorView().getWindowVisibleDisplayFrame(rect);

                // Get the height of Status Bar
                int statusBarHeight = rect.top;

                // Get the height occupied by the decoration contents 
                int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();

                // Calculate titleBarHeight by deducting statusBarHeight from contentViewTop  
                int titleBarHeight = contentViewTop - statusBarHeight; 
                Log.i("MY", "titleHeight = " + titleBarHeight + " statusHeight = " + statusBarHeight + " contentViewTop = " + contentViewTop); 

                // By now we got the height of titleBar & statusBar
                // Now lets get the screen size
                DisplayMetrics metrics = new DisplayMetrics();
                getWindowManager().getDefaultDisplay().getMetrics(metrics);   
                int screenHeight = metrics.heightPixels;
                int screenWidth = metrics.widthPixels;
                Log.i("MY", "Actual Screen Height = " + screenHeight + " Width = " + screenWidth);   

                // Now calculate the height that our layout can be set
                // If you know that your application doesn't have statusBar added, then don't add here also. Same applies to application bar also 
                layoutHeight.set(screenHeight - (titleBarHeight + statusBarHeight));
                Log.i("MY", "Layout Height = " + layoutHeight);   

            // Lastly, set the height of the layout       
            FrameLayout.LayoutParams rootParams = (FrameLayout.LayoutParams)root.getLayoutParams();
            rootParams.height = layoutHeight.get();
            root.setLayoutParams(rootParams);
        }
    });

return layoutHeight.get();
}

Use HttpServerUtility.UrlEncode

In my case easiest way to get browser headers was to use php. It appends headers to file and prints them to test page.

<?php
$fp = fopen('m:/temp/requests.txt', 'a');
$time = $_SERVER['REQUEST_TIME'];
fwrite($fp, $time  "\n");
echo "$time.<br>";
foreach (getallheaders() as $name => $value) {
    $cur_hd = "$name: $value\n";
    fwrite($fp, $cur_hd);
    echo "$cur_hd.<br>";
}
fwrite($fp, "***\n");
fclose($fp);
?>

You are getting NullPointerException as the "output" is null when the while loop ends. You can collect the output in some buffer and then use it, something like this-

    StringBuilder buffer = new StringBuilder();
    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
        buffer.append(output);
    }
    output = buffer.toString(); // now you have the output
    conn.disconnect();

I found that piping the array to the Out-String cmdlet works well too.

For example:

PS C:\> $a  | out-string

This
Is
a
cat

It depends on your end goal as to which method is the best to use.

Follow the following steps:

1. Open the XAMPP control panel and click on the shell and open the shell.
2. In the shell run the following : mysql -h localhost -u root -p and press enter. It will as for a password, by default the password is blank so just press enter
3. Then just run the following query SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpassword'); and press enter and your password is updated for root user on localhost

For iOS 10+, you can use this method for knowing when your notification is clicked irrespective of the state of the app.

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    //Notification clicked
    completionHandler()
}

The "ternary expression" x ? y : z can only be used for conditional assignment. That is, you could do something like:

String mood = inProfit() ? "happy" : "sad";

because the ternary expression is returning something (of type String in this example).

It's not really meant to be used as a short, in-line if-else. In particular, you can't use it if the individual parts don't return a value, or return values of incompatible types. (So while you could do this if both method happened to return the same value, you shouldn't invoke it for the side-effect purposes only).

So the proper way to do this would just be with an if-else block:

if (jXPanel6.isVisible()) {
    jXPanel6.setVisible(true);
}
else {
    jXPanel6.setVisible(false);
}

which of course can be shortened to

jXPanel6.setVisible(jXPanel6.isVisible());

Both of those latter expressions are, for me, more readable in that they more clearly communicate what it is you're trying to do. (And by the way, did you get your conditions the wrong way round? It looks like this is a no-op anyway, rather than a toggle).

Don't mix up low character count with readability. The key point is what is most easily understood; and mildly misusing language features is a definite way to confuse readers, or at least make them do a mental double-take.

Do this. Add this to the bottom of your doc just before you close the body tag.

<script>
    function canvasToImg() {
      var canvas = document.getElementById("yourCanvasID");
      var ctx=canvas.getContext("2d");
      //draw a red box
      ctx.fillStyle="#FF0000";
      ctx.fillRect(10,10,30,30);

      var url = canvas.toDataURL();

      var newImg = document.createElement("img"); // create img tag
      newImg.src = url;
      document.body.appendChild(newImg); // add to end of your document
    }

    canvasToImg(); //execute the function
</script>

Of course somewhere in your doc you need the canvas tag that it will grab.

<canvas id="yourCanvasID" />

int size = myHashSet.size();
int item = new Random().nextInt(size); // In real life, the Random object should be rather more shared than this
int i = 0;
for(Object obj : myhashSet)
{
    if (i == item)
        return obj;
    i++;
}

You could also use the store library which performs it for you with crossbrowser ability.

example :

// Store current user
store.set('user', { name:'Marcus' })

// Get current user
store.get('user')

// Remove current user
store.remove('user')

// Clear all keys
store.clearAll()

// Loop over all stored values
store.each(function(value, key) {
    console.log(key, '==', value)
})

Files.lines

Java 8+ has a nice and short way using NIO using Files.lines. Note that you have to close the stream using try-with-resources:

long lineCount;
try (Stream<String> stream = Files.lines(path, StandardCharsets.UTF_8)) {
  lineCount = stream.count();
}

If you don't specify the character encoding, the default one used is UTF-8. You may specify an alternate encoding to match your particular data file as shown in the example above.

Replace get with jsonp:

 $http.jsonp('http://mywebservice').success(function ( data ) {
    alert(data);
    });
}

If you are going to be changing a String many times, then it is usually more efficient to use a StringBuilder (but measure your performance to find out):

String str = "The rain in Spain falls mainly on the plain";
StringBuilder sb = new StringBuilder(str);
// do your replacing in sb - although you'll find this trickier than simply using String
String newStr = sb.toString();

Every time you do a replace on a String, a new String object is created, because Strings are immutable. StringBuilder is mutable, that is, it can be changed as much as you want.

protected void Button1_Click(object sender, EventArgs e)
   {


       using (SqlConnection connection1 = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\Database.mdf;Integrated Security=True;User Instance=True"))
       {
           connection1.Open();

           // Start a local transaction.
           SqlTransaction sqlTran = connection1.BeginTransaction();

           // Enlist a command in the current transaction.
           SqlCommand command = connection1.CreateCommand();
           command.Transaction = sqlTran;

           try
           {
               // Execute two separate commands.
               command.CommandText =
                "insert into [doctor](drname,drspecialization,drday) values ('a','b','c')";
               command.ExecuteNonQuery();
               command.CommandText =
                "insert into [doctor](drname,drspecialization,drday) values ('x','y','z')";
               command.ExecuteNonQuery();

               // Commit the transaction.
               sqlTran.Commit();
               Label3.Text = "Both records were written to database.";
           }
           catch (Exception ex)
           {
               // Handle the exception if the transaction fails to commit.
               Label4.Text = ex.Message;


               try
               {
                   // Attempt to roll back the transaction.
                   sqlTran.Rollback();
               }
               catch (Exception exRollback)
               {
                   // Throws an InvalidOperationException if the connection 
                   // is closed or the transaction has already been rolled 
                   // back on the server.
                   Label5.Text = exRollback.Message;

               }
           }
       }


   }

If you are using Java 7+, you may want to use NIO.2, e.g.:

❍ Code:

public static void main(String[] args) throws Exception {

    File file = new File("test.csv");

    List<String> lines = Files.readAllLines(file.toPath(), 
            StandardCharsets.UTF_8);

    for (String line : lines) {
        String[] array = line.split(",", -1);
        System.out.println(array[0]);
    }

}

❍ Output:

a
1RW
1RW
1RW
1RW
1RW
1RW
1R1W
1R1W
1R1W

The need is the possible desire for reproducible results, which may for example come from trying to debug your program, or of course from trying to redo what it does:

These two results we will "never" reproduce as I just asked for something "random":

R> sample(LETTERS, 5)
[1] "K" "N" "R" "Z" "G"
R> sample(LETTERS, 5)
[1] "L" "P" "J" "E" "D"

These two, however, are identical because I set the seed:

R> set.seed(42); sample(LETTERS, 5)
[1] "X" "Z" "G" "T" "O"
R> set.seed(42); sample(LETTERS, 5)
[1] "X" "Z" "G" "T" "O"
R> 

There is vast literature on all that; Wikipedia is a good start. In essence, these RNGs are called Pseudo Random Number Generators because they are in fact fully algorithmic: given the same seed, you get the same sequence. And that is a feature and not a bug.

graphics.h appears to something once bundled with Borland and/or Turbo C++, in the 90's.

http://www.daniweb.com/software-development/cpp/threads/17709/88149#post88149

It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

All of these answers appear to be incomplete and/or kludges. Looking at the RestTemplate interface, it sure looks like it is intended to have a ClientHttpRequestFactory injected into it, and then that requestFactory will be used to create the request, including any customizations of headers, body, and request params.

You either need a universal ClientHttpRequestFactory to inject into a single shared RestTemplate or else you need to get a new template instance via new RestTemplate(myHttpRequestFactory).

Unfortunately, it looks somewhat non-trivial to create such a factory, even when you just want to set a single Authorization header, which is pretty frustrating considering what a common requirement that likely is, but at least it allows easy use if, for example, your Authorization header can be created from data contained in a Spring-Security Authorization object, then you can create a factory that sets the outgoing AuthorizationHeader on every request by doing SecurityContextHolder.getContext().getAuthorization() and then populating the header, with null checks as appropriate. Now all outbound rest calls made with that RestTemplate will have the correct Authorization header.

Without more emphasis placed on the HttpClientFactory mechanism, providing simple-to-overload base classes for common cases like adding a single header to requests, most of the nice convenience methods of RestTemplate end up being a waste of time, since they can only rarely be used.

I'd like to see something simple like this made available

@Configuration
public class MyConfig {
  @Bean
  public RestTemplate getRestTemplate() {
    return new RestTemplate(new AbstractHeaderRewritingHttpClientFactory() {
        @Override
        public HttpHeaders modifyHeaders(HttpHeaders headers) {
          headers.addHeader("Authorization", computeAuthString());
          return headers;
        }
        public String computeAuthString() {
          // do something better than this, but you get the idea
          return SecurityContextHolder.getContext().getAuthorization().getCredential();
        }
    });
  }
}

At the moment, the interface of the available ClientHttpRequestFactory's are harder to interact with than that. Even better would be an abstract wrapper for existing factory implementations which makes them look like a simpler object like AbstractHeaderRewritingRequestFactory for the purposes of replacing just that one piece of functionality. Right now, they are very general purpose such that even writing those wrappers is a complex piece of research.

I had a similar problem when migrating an old database to a new version.

Switch the MySQL mode to not use STRICT.

Error Code: 1406. Data too long for column - MySQL

Use the csv module:

import csv

with open("test.csv", "r") as f:
    reader = csv.reader(f, delimiter="\t")
    for i, line in enumerate(reader):
        print 'line[{}] = {}'.format(i, line)

Output:

line[0] = ['Year:', 'Dec:', 'Jan:']
line[1] = ['1', '50', '60']
line[2] = ['2', '25', '50']
line[3] = ['3', '30', '30']
line[4] = ['4', '40', '20']
line[5] = ['5', '10', '10']

For truncate:

var intvalue = Math.floor(value);

For round:

var intvalue = Math.round(value);

If you try to console log query object directly you will get error TypeError: Cannot convert object to primitive value

So I would suggest use JSON.stringify

const http = require('http');
const url = require('url');

const server = http.createServer((req, res) => {
    const parsedUrl = url.parse(req.url, true);

    const path = parsedUrl.pathname, query = parsedUrl.query;
    const method = req.method;

    res.end("hello world\n");

    console.log(`Request received on: ${path} + method: ${method} + query: 
    ${JSON.stringify(query)}`);
    console.log('query: ', query);
  });


  server.listen(3000, () => console.log("Server running at port 3000"));

So doing curl http://localhost:3000/foo\?fizz\=buzz will return Request received on: /foo + method: GET + query: {"fizz":"buzz"}

This worked for me. Running android API 19 and above.

If you like to have the timestamp without the timezone but local timezone do

git log -1 --format=%cd --date=local

you can add this style to your buttons:

#button1 , #button2 {
display:inline-block;
/* additional code */
}

You can use the onload="" HTML attribute and use JavaScript to adjust the opacity style of your element.

Leave your CSS as you proposed. Edit your HTML code to:

<body onload="document.getElementById(test).style.opacity='1'">
    <div id="test">
        <p>?This is a test</p>
    </div>
</body>

This also works to fade-in the complete page when finished loading:

HTML:

<body onload="document.body.style.opacity='1'">
</body>

CSS:

body{ 
    opacity: 0;
    transition: opacity 2s;
    -webkit-transition: opacity 2s; /* Safari */
}

Check the W3Schools website: transitions and an article for changing styles with JavaScript.

You can install this Jenkins Console log plugin to write the log in your workspace as a post build step.

You have to build the plugin yourself and install the plugin manually.

Next, you can add a post build step like that:

With an additional post build step (shell script), you will be able to grep your log.

I hope it helped :)

Actually, the correct solution is:

composer require vendor/package

Taken from the CLI documentation for Composer:

The require command adds new packages to the composer.json file from the current directory.

php composer.phar require

After adding/changing the requirements, the modified requirements will be installed or updated.

If you do not want to choose requirements interactively, you can just pass them to the command.

php composer.phar require vendor/package:2.* vendor/package2:dev-master

While it is true that composer update installs new packages found in composer.json, it will also update the composer.lock file and any installed packages according to any fuzzy logic (> or * chars after the colons) found in composer.json! This can be avoided by using composer update vendor/package, but I wouldn't recommend making a habit of it, as you're one forgotten argument away from a potentially broken project…

Keep things sane and stick with composer require vendor/package for adding new dependencies!

Cookies are basically text, so you can store an array by encoding it as a JSON string (see json_encode). Be aware that there is a limit on the length of the string you can store though.

SWIFT 4.x :

self.mConstraint.constant = 100.0
UIView.animate(withDuration: 0.3) {
        self.view.layoutIfNeeded()
}

Example with completion:

self.mConstraint.constant = 100
UIView.animate(withDuration: 0.3, animations: {
        self.view.layoutIfNeeded()
    }, completion: {res in
        //Do something
})

You can try this

Dim occurCount As Integer = Len(testStr) - Len(testStr.Replace(testCharStr, ""))

This functionality is not built-in to C# 5 or below.
Update: C# 6 now supports string interpolation, see newer answers.

The recommended way to do this would be with String.Format:

string name = "Scott";
string output = String.Format("Hello {0}", name);

However, I wrote a small open-source library called SmartFormat that extends String.Format so that it can use named placeholders (via reflection). So, you could do:

string name = "Scott";
string output = Smart.Format("Hello {name}", new{name}); // Results in "Hello Scott".

Hope you like it!

the correct answer is good , but

OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());

not work for me , instead of it , use :

byte[] outputBytes = rootJsonObject.getBytes("UTF-8");
OutputStream os = con.getOutputStream();
os.write(outputBytes);

This should work in modern browsers:

input[value]:not([value=""])

It selects all inputs with value attribute and then select inputs with non empty value among them.

The accepted answer works but doesn't move back to previous position if you scroll above it. It is always stuck to the top after being placed there.

  $(window).scroll(function(e) {
    $el = $('.fixedElement');
    if ($(this).scrollTop() > 42 && $el.css('position') != 'fixed') {
      $('.fixedElement').css( 'position': 'fixed', 'top': '0px');

    } else if ($(this).scrollTop() < 42 && $el.css('position') != 'relative') {
      $('.fixedElement').css( 'relative': 'fixed', 'top': '42px');
//this was just my previous position/formating
    }
  });

jleedev's response whould work, but I wasn't able to get it to work. His example page also didn't work (for me).

I see 2 options.

1. Using numpy:

   property_a = numpy.array([545., 656., 5.4, 33.])
   property_b = numpy.array([ 1.2,  1.3, 2.3, 0.3])
   good_objects = [True, False, False, True]
   good_indices = [0, 3]
   property_asel = property_a[good_objects]
   property_bsel = property_b[good_indices]
   

2. Using a list comprehension and zip it:

   property_a = [545., 656., 5.4, 33.]
   property_b = [ 1.2,  1.3, 2.3, 0.3]
   good_objects = [True, False, False, True]
   good_indices = [0, 3]
   property_asel = [x for x, y in zip(property_a, good_objects) if y]
   property_bsel = [property_b[i] for i in good_indices]
   

I would like to recommend you to use another way to do this.

I guess you want to show start up screen while the program is starting, if it is already running in backend, don't show it.

Your application can continuously write current time to a specific file. While your application is starting, check the last timestamp, if current_time-last_time>the time range your specified for writing the latest time, it means your application is stopped, either killed by system or user himself.

I did something like that :

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View view = super.getView(position, convertView, parent);

    TextView textView = (TextView) view.findViewById(android.R.id.text1);
    textView.setHeight(30);
    textView.setMinimumHeight(30);

    /*YOUR CHOICE OF COLOR*/
    textView.setTextColor(Color.BLACK);

    return view;
}

You must put the both fields textView.setHeight(30); textView.setMinimumHeight(30); or it won't change anything. For me it worked & i had the same problem.

I was having the same error (with ElementTree). In my case it was because of encodings, and I was able to solve it without having to use an external library. Hope this helps other people finding this question based on the title. (reference)

import xml.etree.ElementTree as ET
parser = ET.XMLParser(encoding="utf-8")
tree = ET.fromstring(xmlstring, parser=parser)

EDIT: Based on comments, this answer might be outdated. But this did work back when it was answered...

Another way is to use the DateTime class, this way you can also specify the timezone. Note: PHP 5.3 or higher.

// For the current date
function isTodayWeekend() {
    $currentDate = new DateTime("now", new DateTimeZone("Europe/Amsterdam"));
    return $currentDate->format('N') >= 6;
}

If you need to be able to check a certain date string, you can use DateTime::createFromFormat

function isWeekend($date) {
    $inputDate = DateTime::createFromFormat("d-m-Y", $date, new DateTimeZone("Europe/Amsterdam"));
    return $inputDate->format('N') >= 6;
}

The beauty of this way is that you can specify the timezone without changing the timezone globally in PHP, which might cause side-effects in other scripts (for ex. Wordpress).

You can change the separator either by setting a locale or using the DecimalFormatSymbols.

If you want the grouping separator to be a point, you can use an european locale:

NumberFormat nf = NumberFormat.getNumberInstance(Locale.GERMAN);
DecimalFormat df = (DecimalFormat)nf;

Alternatively you can use the DecimalFormatSymbols class to change the symbols that appear in the formatted numbers produced by the format method. These symbols include the decimal separator, the grouping separator, the minus sign, and the percent sign, among others:

DecimalFormatSymbols otherSymbols = new DecimalFormatSymbols(currentLocale);
otherSymbols.setDecimalSeparator(',');
otherSymbols.setGroupingSeparator('.'); 
DecimalFormat df = new DecimalFormat(formatString, otherSymbols);

currentLocale can be obtained from Locale.getDefault() i.e.:

Locale currentLocale = Locale.getDefault();

Unfortunately, It is not possible to compare datetime towards varchar using 'LIKE' But the desired output is possible in another way.

    select * from record where datediff(dd,[record].[register_date],'2009-10-10')=0

Just to add my 2 cents, I'd write my own PHP Script:

http://php.net/manual/en/function.mail.php

There are lots of ways to do the attachment in the examples on that page.

For what it's worth, I just created a directory on an ext4 file system with 1,000,000 files in it, then randomly accessed those files through a web server. I didn't notice any premium on accessing those over (say) only having 10 files there.

This is radically different from my experience doing this on ntfs a few years back.

Filter() from the base package is the perfect function for that use-case: You simply have to code:

Filter(is.numeric, x)

It is also much faster than select_if():

library(microbenchmark)
microbenchmark(
    dplyr::select_if(mtcars, is.numeric),
    Filter(is.numeric, mtcars)
)

returns (on my computer) a median of 60 microseconds for Filter, and 21 000 microseconds for select_if (350x faster).

You can create the Python dictionary and serialize it to JSON in one line and it's not even ugly.

my_json_string = json.dumps({'key1': val1, 'key2': val2})

I was debugging the problem for the better part of the day and when I was close to burning the building I discovered the Process Monitor tool from Sysinternals.

Set it to monitor w3wp.exe and check last events before it exits after you fire a request in the browser. Hope that helps further readers.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

Inside the function parameter list, char arr[] is absolutely equivalent to char *arr, so the pair of definitions and the pair of declarations are equivalent.

void function(char arr[]) { ... }
void function(char *arr)  { ... }

void function(char arr[]);
void function(char *arr);

The issue is the calling context. You provided a string literal to the function; string literals may not be modified; your function attempted to modify the string literal it was given; your program invoked undefined behaviour and crashed. All completely kosher.

Treat string literals as if they were static const char literal[] = "string literal"; and do not attempt to modify them.

You said :

Maybe my data.frame is not in a good format?

Yes this is true. Your data is in the wide format You need to put it in the long format. Generally speaking, long format is better for variables comparison.

Using reshape2 for example , you do this using melt:

dat.m <- melt(dat,id.vars = "Rank") ## just melt(dat) should work

Then you get your barplot:

ggplot(dat.m, aes(x = Rank, y = value,fill=variable)) +
    geom_bar(stat='identity')

But using lattice and barchart smart formula notation , you don't need to reshape your data , just do this:

barchart(F1+F2+F3~Rank,data=dat)

I think you need to add some context to your question. However, basic information about these things can be found here:

window.opener https://developer.mozilla.org/en-US/docs/Web/API/Window.opener

I've used window.opener mostly when opening a new window that acted as a dialog which required user input, and needed to pass information back to the main window. However this is restricted by origin policy, so you need to ensure both the content from the dialog and the opener window are loaded from the same origin.

window.parent https://developer.mozilla.org/en-US/docs/Web/API/Window.parent

I've used this mostly when working with IFrames that need to communicate with the window object that contains them.

window.top https://developer.mozilla.org/en-US/docs/Web/API/Window.top

This is useful for ensuring you are interacting with the top level browser window. You can use it for preventing another site from iframing your website, among other things.

If you add some more detail to your question, I can supply other more relevant examples.

UPDATE: There are a few ways you can handle your situation.
You have the following structure:

• Main Window
  • Dialog 1
    • Dialog 2 Opened By Dialog 1

When Dialog 1 runs the code to open Dialog 2, after creating Dialog 2, have dialog 1 set a property on Dialog 2 that references the Dialog1 opener.

So if "childwindow" is you variable for the dialog 2 window object, and "window" is the variable for the Dialog 1 window object. After opening dialog 2, but before closing dialog 1 make an assignment similar to this:

childwindow.appMainWindow = window.opener

After making the assignment above, close dialog 1. Then from the code running inside dialog2, you should be able to use window.appMainWindow to reference the main window, window object.

Hope this helps.

To delete bin and obj before build add to project file:

<Target Name="BeforeBuild">
    <!-- Remove obj folder -->
    <RemoveDir Directories="$(BaseIntermediateOutputPath)" />
    <!-- Remove bin folder -->
    <RemoveDir Directories="$(BaseOutputPath)" />
</Target>

Here is article: How to remove bin and/or obj folder before the build or deploy

Best way to load local images in react is as follows

For example, Keep all your images(or any assets like videos, fonts) in the public folder as shown below.

Simply write <img src='/assets/images/Call.svg' /> to access the Call.svg image from any of your react component

Note: Keeping your assets in public folder ensures that, you can access it from anywhere from the project, by just giving '/path_to_image' and no need for any path traversal '../../' like this

if you happened to use NLog in your ASP.net project, you can add a Debugger target:

<targets>
    <target name="debugger" xsi:type="Debugger"
            layout="${date:format=HH\:mm\:ss}|${pad:padding=5:inner=${level:uppercase=true}}|${message} "/>

and writes logs to this target for the levels you want:

<rules>
    <logger name="*" minlevel="Trace" writeTo="debugger" />

now you have console output just like Jetty in "Output" window of VS, and make sure you are running in Debug Mode(F5).

1 : if you are interested only in the static block of the class , the loading the class only would do , and would execute static blocks then all you need is:

Class.forName("Somthing");

2 : if you are interested in loading the class , execute its static blocks and also want to access its its non static part , then you need an instance and then you need:

Class.forName("Somthing").newInstance();

you can do like this

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

it was the update version of Codemwnci. his code is quite fine and works great except the error message. To avoid error you must change the condition statement.

  // Listen for changes in the text
textField.getDocument().addDocumentListener(new DocumentListener() {
  public void changedUpdate(DocumentEvent e) {
    warn();
  }
  public void removeUpdate(DocumentEvent e) {
    warn();
  }
  public void insertUpdate(DocumentEvent e) {
    warn();
  }

  public void warn() {
     if (textField.getText().length()>0){
       JOptionPane.showMessageDialog(null,
          "Error: Please enter number bigger than 0", "Error Massage",
          JOptionPane.ERROR_MESSAGE);
     }
  }
});

For debugging purposes, you can use the DLL file. You can run it using dotnet ConsoleApp2.dll. If you want to generate an EXE file, you have to generate a self-contained application.

To generate a self-contained application (EXE in Windows), you must specify the target runtime (which is specific to the operating system you target).

Pre-.NET Core 2.0 only: First, add the runtime identifier of the target runtimes in the .csproj file (list of supported RIDs):

<PropertyGroup>
    <RuntimeIdentifiers>win10-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
</PropertyGroup>

The above step is no longer required starting with .NET Core 2.0.

Then, set the desired runtime when you publish your application:

dotnet publish -c Release -r win10-x64
dotnet publish -c Release -r ubuntu.16.10-x64

Most likely, cron is running in a very sparse environment. Check the environment variables cron is using by appending a dummy job which dumps env to a file like this:

* * * * * env > env_dump.txt

Compare that with the output of env in a normal shell session.

You can prepend your own environment variables to the local crontab by defining them at the top of your crontab.

Here's a quick fix to prepend $PATH to the current crontab:

# echo PATH=$PATH > tmp.cron
# echo >> tmp.cron
# crontab -l >> tmp.cron
# crontab tmp.cron

The resulting crontab will look similar to chrissygormley's answer, with PATH defined before the crontab rules.

You may be able to achieve what you want with Class Table Inheritance where you change AlbumTrackReference to AlbumTrack:

class AlbumTrack extends Track { /* ... */ }

And getTrackList() would contain AlbumTrack objects which you could then use like you want:

foreach($album->getTrackList() as $albumTrack)
{
    echo sprintf("\t#%d - %-20s (%s) %s\n", 
        $albumTrack->getPosition(),
        $albumTrack->getTitle(),
        $albumTrack->getDuration()->format('H:i:s'),
        $albumTrack->isPromoted() ? ' - PROMOTED!' : ''
    );
}

You will need to examine this throughly to ensure you don't suffer performance-wise.

Your current set-up is simple, efficient, and easy to understand even if some of the semantics don't quite sit right with you.

From a former string concatenater (sp?) you should really consider using String.Format instead of concatenation.

    Dim s1 As String
    Dim i As Integer
    s1 = "Hello"
    i = 1
    String.Format("{0} {1}", s1, i)

It makes things a lot easier to read and maintain and I believe makes your code look more professional. See: code better – use string.format. Although not everyone agrees When is it better to use String.Format vs string concatenation?

I think you should only throw an exception when there's nothing you can do to get out of your current state. For example if you are allocating memory and there isn't any to allocate. In the cases you mention you can clearly recover from those states and can return an error code back to your caller accordingly.

You will see plenty of advice, including in answers to this question, that you should throw exceptions only in "exceptional" circumstances. That seems superficially reasonable, but is flawed advice, because it replaces one question ("when should I throw an exception") with another subjective question ("what is exceptional"). Instead, follow the advice of Herb Sutter (for C++, available in the Dr Dobbs article When and How to Use Exceptions, and also in his book with Andrei Alexandrescu, C++ Coding Standards): throw an exception if, and only if

• a precondition is not met (which typically makes one of the following impossible) or
• the alternative would fail to meet a post-condition or
• the alternative would fail to maintain an invariant.

Why is this better? Doesn't it replace the question with several questions about preconditions, postconditions and invariants? This is better for several connected reasons.

• Preconditions, postconditions and invariants are design characteristics of our program (its internal API), whereas the decision to throw is an implementation detail. It forces us to bear in mind that we must consider the design and its implementation separately, and our job while implementing a method is to produce something that satisfies the design constraints.
• It forces us to think in terms of preconditions, postconditions and invariants, which are the only assumptions that callers of our method should make, and are expressed precisely, enabling loose coupling between the components of our program.
• That loose coupling then allows us to refactor the implementation, if necessary.
• The post-conditions and invariants are testable; it results in code that can be easily unit tested, because the post-conditions are predicates our unit-test code can check (assert).
• Thinking in terms of post-conditions naturally produces a design that has success as a post-condition, which is the natural style for using exceptions. The normal ("happy") execution path of your program is laid out linearly, with all the error handling code moved to the catch clauses.

The easiest solution I found to this problem was to downgrade the MySql from MySQL Workbench to MySQL Version 1.2.17. I had browsed some MySQL Forums, where it was said that the timeout time in MySQL Workbech has been hard coded to 600 and some suggested methods to change it didn't work for me. If someone is facing the same problem with workbench you could try downgrading too.

For completeness:

Does Add to homescreen work on Chrome for iOS?

No.

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

This should work. I would trim the whitespace from the input field first of all:

if($('#Field').val() != "") {
    var value = $('#Field').val().replace(/^\s\s*/, '').replace(/\s\s*$/, '');
    var intRegex = /^\d+$/;
    if(!intRegex.test(value)) {
        errors += "Field must be numeric.<br/>";
        success = false;
    }
} else {
    errors += "Field is blank.</br />";
    success = false;
}

                {

                    HttpPostedFileBase filebase = new HttpPostedFileWrapper(pic);
                    var fileName = Path.GetFileName(filebase.FileName);


                    string fileExtension = System.IO.Path.GetExtension(fileName);

                    if (fileExtension == ".xls" || fileExtension == ".xlsx")
                    {
                        string FileName = Guid.NewGuid().GetHashCode().ToString("x");
                        string dirLocation = Server.MapPath("~/Content/PacketExcel/");
                        if (!Directory.Exists(dirLocation))
                        {
                            Directory.CreateDirectory(dirLocation);
                        }
                        string fileLocation = Server.MapPath("~/Content/PacketExcel/") + FileName + fileExtension;
                        filebase.SaveAs(fileLocation);
}
}

most simple solution would be to set a boolean var. if to true where you do the insert statement and then in the outter loop check this and insert the tweet there if the boolean is true...

Several sites provide reasonable cheat sheets or HOWTOs for tables and images. Top on my list are:

• Pandoc readme, specifically tables

• RStudio's RMarkdown, more details in basics (including tables) and a rewrite of pandoc's markdown.

Pictures are very simple to use but do not offer the ability to adjust the image to fit the page (see Update, below). To adjust the image properties (size, resolution, colors, border, etc), you'll need some form of image editor. I find I can do everything I need with one of ImageMagick, GIMP, or InkScape, all free and open source.

To add a picture, use:

![Caption for the picture.](/path/to/image.png)

I know pandoc supports PNG and JPG, which should meet most of your needs.

You do have control over image size if you are creating it in R (e.g., a plot). This can be done either directly in the command to create the image or, even better, via options if you are using knitr (highly recommended ... check out chunk options, specifically under Plots).

I strongly recommend perusing these tutorials; markdown is very handy and has many features most people don't use on a regular basis but really like once they learn it. (SO is not necessarily the best place to ask questions that are answered very directly in these tutorials.)

Update, 2019-Aug-31

Some time ago, pandoc incorporated "link_attributes" for images (apparently in 2015, with commit jgm/pandoc#244cd56). "Resizing images" can be done directly. For example:

![unchanged image](foo.jpg)
![much-smaller image](foo.jpg){#id .class width=30 height=20px}
![half-size image](foo.jpg){#id .class width=50% height=50%}

The dimensions can be provided with no units (pixels assumed), or with "px, cm, mm, in, inch and %" (ref: https://pandoc.org/MANUAL.html, search for link_attributes).

(I'm not certain that CommonMark has implemented this, though there was a lengthy discussion.)

Simply check that the directory/package of the class is marked as "Sources Root". I believe the package should be application or execution in your case.

To do so, right click on the package, and select Mark Directory As->Sources Root.

SharedPreferences mPrefs;
final String welcomeScreenShownPref = "welcomeScreenShown";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mPrefs = PreferenceManager.getDefaultSharedPreferences(this);

    // second argument is the default to use if the preference can't be found
    Boolean welcomeScreenShown = mPrefs.getBoolean(welcomeScreenShownPref, false);

    if (!welcomeScreenShown) {
        // here you can launch another activity if you like

        SharedPreferences.Editor editor = mPrefs.edit();
        editor.putBoolean(welcomeScreenShownPref, true);
        editor.commit(); // Very important to save the preference

    }
}

CMake 3.13 on Ubuntu 16.04

This approach is more flexible because it doesn't constraint MY_VARIABLE to a type:

$ cat CMakeLists.txt 
message("MY_VARIABLE=${MY_VARIABLE}")
if( MY_VARIABLE ) 
    message("MY_VARIABLE evaluates to True")
endif()

$ mkdir build && cd build

$ cmake ..
MY_VARIABLE=
-- Configuring done

-- Build files have been written to: /path/to/build

$ cmake .. -DMY_VARIABLE=True

-- Build files have been written to: /path/to/build

$ cmake .. -DMY_VARIABLE=False
MY_VARIABLE=False
-- Configuring done

$ cmake .. -DMY_VARIABLE=1

$ cmake .. -DMY_VARIABLE=0

How about

a["abc"] = [1, 2]

This will result in:

>>> a
{'abc': [1, 2]}

Is that what you were looking for?

I am not saying that you have to abandon PHP, but you need different technologies here.

Let's start off simple (without Akamai :-)) and think about the implications here. Video, chat, etc. - it's all client-side in the beginning. The user has a webcam, you want to grab the signal somehow and send it to the server. There is no PHP so far.

I know that Flash supports this though (check this tutorial on webcams and flash) so you could use Flash to transport the content to the server. I think if you'll stay with Flash, then Flex (flex and webcam tutorial) is probably a good idea to look into.

So those are just the basics, maybe it gives you an idea of where you need to research because obviously this won't give you a full video chat inside your app yet. For starters, you will need some sort of way to record the streams and re-publish them so others see other people from the chat, etc..

I'm also not sure how much traffic and bandwidth this is gonna consume though and generally, you will need way more than a Stackoverflow question to solve this issue. Best would be to do a full spec of your app and then hire some people to help you build it.

HTH!

I had the same issue, only using a .pug file (similar to .jade). I realized that it was also a space issue, following the end of my closing parentheses. In my example, you need to highlight the text after (placeholder="YOUR MESSAGE") to see:

BEFORE:

form.form-horizontal(method='POST')
  .form-group
    textarea.form-control(placeholder="YOUR MESSAGE") 
  .form-group  
    button.btn.btn-primary(type='submit') SUBMIT

AFTER:

form.form-horizontal(method='POST')
  .form-group
    textarea.form-control(placeholder="YOUR MESSAGE")
  .form-group  
    button.btn.btn-primary(type='submit') SUBMIT

alert(xml.data[0].city);

use xml.data["Data"][0].city instead

Swift 4 This is just awesome

  self.imgViewPreview.transform = CGAffineTransform(scaleX: 0, y: 0)
          UIView.animate(withDuration: 1, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0, options: .curveEaseOut, animations: {
              self.imgViewPreview.image = newImage
              self.imgViewPreview.transform = .identity
          }, completion: nil)

The error is due the fact that you are passing a wrong to strcat(). Look at strcat()'s prototype:

   char *strcat(char *dest, const char *src);

But you pass char as the second argument, which is obviously wrong.

Use snprintf() instead.

char str[1024] = "Hello World";
char tmp = '.';
size_t len = strlen(str);

snprintf(str + len, sizeof str - len, "%c", tmp);

As commented by OP:

That was just a example with Hello World to describe the Problem. It must be empty as first in my real program. Program will fill it later. The problem just contains to add a char/int to an char Array

In that case, snprintf() can handle it easily to "append" integer types to a char buffer too. The advantage of snprintf() is that it's more flexible to concatenate various types of data into a char buffer.

For example to concatenate a string, char and an int:

char str[1024];
ch tmp = '.';
int i = 5;

// Fill str here

snprintf(str + len, sizeof str - len, "%c%d", str, tmp, i);

.NET Example as requested:

using (client)
{
    var existingObject = client.ListObjects(requestForExisingFile).S3Objects; 
    if (existingObject.Count == 1)
    {
        var requestCopyObject = new CopyObjectRequest()
        {
            SourceBucket = BucketNameProd,
            SourceKey = objectToMerge.Key,
            DestinationBucket = BucketNameDev,
            DestinationKey = newKey
        };
        client.CopyObject(requestCopyObject);
    }
}

with client being something like

var config = new AmazonS3Config { CommunicationProtocol = Protocol.HTTP, ServiceURL = "s3-eu-west-1.amazonaws.com" };
var client = AWSClientFactory.CreateAmazonS3Client(AWSAccessKey, AWSSecretAccessKey, config);

There might be a better way, but it's just some quick code I wrote to get some files transferred.

Delete all files under the .m2 repository folder and rebuild the project.
