Tumblr has a public API that provides JSON. You can get a dump of posts using a simple url like http://puppygifs.tumblr.com/api/read/json.

You may do as follows to Populate treeView with parent and child node. And also with display and value member of parent and child nodes:

   arrayRoot = taskData.GetRocordForRoot();  // iterate through database table
    for (int j = 0; j <arrayRoot.length; j++) { 
                TreeNode root = new TreeNode();  // Creating new root node
                root.Text = "displayString";
                root.Tag = "valueString";
                treeView1.Nodes.Add(root); //Adding the root node

             arrayChild = taskData.GetRocordForChild();// iterate through database table
                for (int i = 0; i < arrayChild.length; i++) {
                    TreeNode child = new TreeNode(); // creating child node
                    child.Text = "displayString"
                    child.Tag = "valueString";
                    root.Nodes.Add(child); // adding child node
                }

            }

yourNode.Toggle(); //use that function on your node, it toggles it

This can be accomplished in a 'nicer' way using only binding and the GalaSoft MVVM Light library's EventToCommand. In your VM add a command which will be called when the selected item is changed, and initialize the command to perform whatever action is necessary. In this example I used a RelayCommand and will just set the SelectedCluster property.

public class ViewModel
{
    public ViewModel()
    {
        SelectedClusterChanged = new RelayCommand<Cluster>( c => SelectedCluster = c );
    }

    public RelayCommand<Cluster> SelectedClusterChanged { get; private set; } 

    public Cluster SelectedCluster { get; private set; }
}

Then add the EventToCommand behavior in your xaml. This is really easy using blend.

<TreeView
      x:Name="lstClusters"
      ItemsSource="{Binding Path=Model.Clusters}" 
      ItemTemplate="{StaticResource HoofdCLusterTemplate}">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="SelectedItemChanged">
            <GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding SelectedClusterChanged}" CommandParameter="{Binding ElementName=lstClusters,Path=SelectedValue}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
</TreeView>

using remove() method you can able to remove.

getLogout(data){
        return this.sessionModel
        .remove({session_id: data.sid})
        .exec()
        .then(data =>{
            return "signup successfully"
        })
    }

A Stacked bar chart should suffice:

Setup data as follows

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

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

(example prepared in Excel 2010)

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

I was able to correct the flaw by changing the file below:

C:\Windows\System32\inetsrv\config\applicationHost.config

In:

<application path="/" applicationPool="ASP.NET v4.0">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\Bonobo.Git.Server" />
</application>
<application path="/Bonobo.Git.Server" applicationPool="ASP.NET v4.0">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\Bonobo.Git.Server" />
</application>

For:

<application path="/">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\" />
</application>
<application path="/Bonobo.Git.Server" applicationPool="ASP.NET v4.0">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\Bonobo.Git.Server" />
</application>

$("#mydiv").css('top', 200);

$("#mydiv").css('left', 200);

it went OK when i used Locale.US parametre in SimpleDateFormat

String dateString = "15 May 2013 17:38:34 +0300";
System.out.println(dateString);

SimpleDateFormat dateFormat = new SimpleDateFormat("dd MMM yyyy HH:mm:ss Z", Locale.US);
DateFormat targetFormat = new SimpleDateFormat("dd MMM yyyy HH:mm", Locale.getDefault());
String formattedDate = null;
Date convertedDate = new Date();
try {
     convertedDate = dateFormat.parse(dateString);
System.out.println(dateString);
formattedDate = targetFormat.format(convertedDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
 System.out.println(convertedDate);

If I may I could give you some new code for the same task, in my code you can create a so called 'document'(not really)and it is saved, and can be opened up again. It is also stored as a string file though(not a document). Here is the code:

#include "iostream"

#include "windows.h"

#include "string"

#include "fstream"

using namespace std;

int main() {

string saveload;


cout << "---------------------------" << endl;
cout << "|enter 'text' to write your document    |" << endl;
cout << "|enter 'open file' to open the document |" << endl;
cout << "----------------------------------------" << endl;
while (true){
    getline(cin, saveload);

    if (saveload == "open file"){
        string filenamet;
        cout << "file name? " << endl;
        getline(cin, filenamet, '*');
        ifstream loadFile;

        loadFile.open(filenamet, ifstream::in);

        cout << "the text you entered was: ";

        while (loadFile.good()){

            cout << (char)loadFile.get();

            Sleep(100);
        }

        cout << "" << endl;

        loadFile.close();

    }

    if (saveload == "text") {
        string filename;
        cout << "file name: " << endl;
        getline(cin, filename,'*');
        string textToSave;
        cout << "Enter your text: " << endl;
        getline(cin, textToSave,'*');

        ofstream saveFile(filename);

        saveFile << textToSave;

        saveFile.close();

    }
}
return 0;
}

Just take this code and change it to serve your purpose. DREAM BIG,THINK BIG, DO BIG

If you enabled the docker remote API (via -Htcp://0.0.0.0:4243 for instance) and know the host machine's hostname or IP address this can be done with a lot of bash.

Within my container's user's bashrc:

export hostIP=$(ip r | awk '/default/{print $3}')
export containerID=$(awk -F/ '/docker/{print $NF;exit;}' /proc/self/cgroup)
export proxyPort=$(
  curl -s http://$hostIP:4243/containers/$containerID/json |
  node -pe 'JSON.parse(require("fs").readFileSync("/dev/stdin").toString()).NetworkSettings.Ports["DESIRED_PORT/tcp"][0].HostPort'
)

The second line grabs the container ID from your local /proc/self/cgroup file.

Third line curls out to the host machine (assuming you're using 4243 as docker's port) then uses node to parse the returned JSON for the DESIRED_PORT.

The only that worked for me was:

Java > Editor > Mark Occurrences:
Check "Mark occurrences of te selected element in the current file."
... and maybe all the ones below.

If you're looking for a document-level key event handling, then binding it during componentDidMount is the best way (as shown by Brad Colthurst's codepen example):

class ActionPanel extends React.Component {
  constructor(props){
    super(props);
    this.escFunction = this.escFunction.bind(this);
  }
  escFunction(event){
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }
  componentDidMount(){
    document.addEventListener("keydown", this.escFunction, false);
  }
  componentWillUnmount(){
    document.removeEventListener("keydown", this.escFunction, false);
  }
  render(){
    return (   
      <input/>
    )
  }
}

Note that you should make sure to remove the key event listener on unmount to prevent potential errors and memory leaks.

EDIT: If you are using hooks, you can use this useEffect structure to produce a similar effect:

const ActionPanel = (props) => {
  const escFunction = useCallback((event) => {
    if(event.keyCode === 27) {
      //Do whatever when esc is pressed
    }
  }, []);

  useEffect(() => {
    document.addEventListener("keydown", escFunction, false);

    return () => {
      document.removeEventListener("keydown", escFunction, false);
    };
  }, []);

  return (   
    <input />
  )
};

An old stupid trick that works in this case... paste code from your editor to ms notepad, then viceversa, and evil character will disappears ! I take inspiration from wyisyg/msword copypaste problem. Notepad++ utf-8 w/out BOM works as well.

 const remoteReq = request({
    method: 'POST',
    uri: 'http://host.com/api/upload',
    headers: {
      'Authorization': 'Bearer ' + req.query.token,
      'Content-Type': req.headers['content-type'] || 'multipart/form-data;'
    }
  })
  req.pipe(remoteReq);
  remoteReq.pipe(res);

Actually I think that (nullableBool ?? false) is a legitimate option especially when you are trying to evaluate a nullable bool in linq.

For example:

array.Select(v => v.nullableBool ?? false)
(from v in array where v.nullableBool ?? false)

Is cleaner in my opinion as opposed to:

array.Select(v => v.nullableBool.HasValue ? v.nullableBool.Value : false)
(from v in array where v.nullableBool.HasValue ? v.nullableBool.Value : false)

In Xcode 4.5 and above, this can now be done by using 'Auto-layouting / Constraints'.

Major advantages are that:

1. You don't need to programmatically set frames at all!
2. If done right, you don't need to bother about resetting frames for orientation changes.
3. Also, device changes needn't bother you (read, no need to code separately for different screen sizes).

A few disadvantages:

1. Not backward compatible - works only for iOS 6 and above.
2. Need to get familiarised (but will save time later on).

Coolest thing is we get to focus on declaring an intent such as:

• I want these two buttons to be of the same width; or
• I need this view to be vertically centered and extend to a max entent of 10 pts from the superview's edge; or even,
• I want this button/label to resize according to the label it is displaying!

Here is a simple tutorial to get introduced to auto-layouting.

For a more details.

It takes some time at first, but it sure looks like it will be well worth the effort.

If you have dates as a string, it might be easier to do it using pandas' Timestamp

import pandas as pd
df = pd.Timestamp("2019-04-12")
print(df.dayofweek, df.weekday_name)

Output:

4 Friday

The method never returns because it's the end of the world and none of your code is going to be executed next.

Your application, in your example, would exit anyway at the same spot in the code, but, if you use System.exit. you have the option of returning a custom code to the enviroment, like, say

System.exit(42);

Who is going to make use of your exit code? A script that called the application. Works in Windows, Unix and all other scriptable environments.

Why return a code? To say things like "I did not succeed", "The database did not answer".

To see how to get the value od an exit code and use it in a unix shell script or windows cmd script, you might check this answer on this site

Using filter_var() will fail for urls with non-ascii chars, e.g. (http://pt.wikipedia.org/wiki/Guimarães). The following function encode all non-ascii chars (e.g. http://pt.wikipedia.org/wiki/Guimar%C3%A3es) before calling filter_var().

Hope this helps someone.

<?php

function validate_url($url) {
    $path = parse_url($url, PHP_URL_PATH);
    $encoded_path = array_map('urlencode', explode('/', $path));
    $url = str_replace($path, implode('/', $encoded_path), $url);

    return filter_var($url, FILTER_VALIDATE_URL) ? true : false;
}

// example
if(!validate_url("http://somedomain.com/some/path/file1.jpg")) {
    echo "NOT A URL";
}
else {
    echo "IS A URL";
}

While technically correct, the other answers would benefit from an explanation of Angular's URL-to-route matching. I don't think you can fully (pardon the pun) understand what pathMatch: full does if you don't know how the router works in the first place.

Let's first define a few basic things. We'll use this URL as an example: /users/james/articles?from=134#section.

1. It may be obvious but let's first point out that query parameters (?from=134) and fragments (#section) do not play any role in path matching. Only the base url (/users/james/articles) matters.

2. Angular splits URLs into segments. The segments of /users/james/articles are, of course, users, james and articles.

3. The router configuration is a tree structure with a single root node. Each Route object is a node, which may have children nodes, which may in turn have other children or be leaf nodes.

The goal of the router is to find a router configuration branch, starting at the root node, which would match exactly all (!!!) segments of the URL. This is crucial! If Angular does not find a route configuration branch which could match the whole URL - no more and no less - it will not render anything.

E.g. if your target URL is /a/b/c but the router is only able to match either /a/b or /a/b/c/d, then there is no match and the application will not render anything.

Finally, routes with redirectTo behave slightly differently than regular routes, and it seems to me that they would be the only place where anyone would really ever want to use pathMatch: full. But we will get to this later.

Default (prefix) path matching

The reasoning behind the name prefix is that such a route configuration will check if the configured path is a prefix of the remaining URL segments. However, the router is only able to match full segments, which makes this naming slightly confusing.

Anyway, let's say this is our root-level router configuration:

const routes: Routes = [
  {
    path: 'products',
    children: [
      {
        path: ':productID',
        component: ProductComponent,
      },
    ],
  },
  {
    path: ':other',
    children: [
      {
        path: 'tricks',
        component: TricksComponent,
      },
    ],
  },
  {
    path: 'user',
    component: UsersonComponent,
  },
  {
    path: 'users',
    children: [
      {
        path: 'permissions',
        component: UsersPermissionsComponent,
      },
      {
        path: ':userID',
        children: [
          {
            path: 'comments',
            component: UserCommentsComponent,
          },
          {
            path: 'articles',
            component: UserArticlesComponent,
          },
        ],
      },
    ],
  },
];

Note that every single Route object here uses the default matching strategy, which is prefix. This strategy means that the router iterates over the whole configuration tree and tries to match it against the target URL segment by segment until the URL is fully matched. Here's how it would be done for this example:

1. Iterate over the root array looking for a an exact match for the first URL segment - users.
2. 'products' !== 'users', so skip that branch. Note that we are using an equality check rather than a .startsWith() or .includes() - only full segment matches count!
3. :other matches any value, so it's a match. However, the target URL is not yet fully matched (we still need to match james and articles), thus the router looks for children.

• The only child of :other is tricks, which is !== 'james', hence not a match.

4. Angular then retraces back to the root array and continues from there.
5. 'user' !== 'users, skip branch.
6. 'users' === 'users - the segment matches. However, this is not a full match yet, thus we need to look for children (same as in step 3).

• 'permissions' !== 'james', skip it.
• :userID matches anything, thus we have a match for the james segment. However this is still not a full match, thus we need to look for a child which would match articles.
  1. We can see that :userID has a child route articles, which gives us a full match! Thus the application renders UserArticlesComponent.

Full URL (full) matching

Example 1

Imagine now that the users route configuration object looked like this:

{
  path: 'users',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

Note the usage of pathMatch: full. If this were the case, steps 1-5 would be the same, however step 6 would be different:

6. 'users' !== 'users/james/articles - the segment does not match because the path configuration users with pathMatch: full does not match the full URL, which is users/james/articles.
7. Since there is no match, we are skipping this branch.
8. At this point we reached the end of the router configuration without having found a match. The application renders nothing.

Example 2

What if we had this instead:

{
  path: 'users/:userID',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'comments',
      component: UserCommentsComponent,
    },
    {
      path: 'articles',
      component: UserArticlesComponent,
    },
  ],
}

users/:userID with pathMatch: full matches only users/james thus it's a no-match once again, and the application renders nothing.

Example 3

Let's consider this:

{
  path: 'users',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      pathMatch: 'full',
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

In this case:

6. 'users' === 'users - the segment matches, but james/articles still remains unmatched. Let's look for children.

• 'permissions' !== 'james' - skip.
• :userID' can only match a single segment, which would be james. However, it's a pathMatch: full route, and it must match james/articles (the whole remaining URL). It's not able to do that and thus it's not a match (so we skip this branch)!

7. Again, we failed to find any match for the URL and the application renders nothing.

As you may have noticed, a pathMatch: full configuration is basically saying this:

Ignore my children and only match me. If I am not able to match all of the remaining URL segments myself, then move on.

Redirects

Any Route which has defined a redirectTo will be matched against the target URL according to the same principles. The only difference here is that the redirect is applied as soon as a segment matches. This means that if a redirecting route is using the default prefix strategy, a partial match is enough to cause a redirect. Here's a good example:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

For our initial URL (/users/james/articles), here's what would happen:

1. 'not-found' !== 'users' - skip it.
2. 'users' === 'users' - we have a match.
3. This match has a redirectTo: 'not-found', which is applied immediately.
4. The target URL changes to not-found.
5. The router begins matching again and finds a match for not-found right away. The application renders NotFoundComponent.

Now consider what would happen if the users route also had pathMatch: full:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    pathMatch: 'full',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

1. 'not-found' !== 'users' - skip it.
2. users would match the first segment of the URL, but the route configuration requires a full match, thus skip it.
3. 'users/:userID' matches users/james. articles is still not matched but this route has children.

• We find a match for articles in the children. The whole URL is now matched and the application renders UserArticlesComponent.

Empty path (path: '')

The empty path is a bit of a special case because it can match any segment without "consuming" it (so it's children would have to match that segment again). Consider this example:

const routes: Routes = [
  {
    path: '',
    children: [
      {
        path: 'users',
        component: BadUsersComponent,
      }
    ]
  },
  {
    path: 'users',
    component: GoodUsersComponent,
  },
];

Let's say we are trying to access /users:

• path: '' will always match, thus the route matches. However, the whole URL has not been matched - we still need to match users!
• We can see that there is a child users, which matches the remaining (and only!) segment and we have a full match. The application renders BadUsersComponent.

Now back to the original question

The OP used this router configuration:

const routes: Routes = [
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
  {
    path: '',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
  {
    path: '**',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
];

If we are navigating to the root URL (/), here's how the router would resolve that:

1. welcome does not match an empty segment, so skip it.
2. path: '' matches the empty segment. It has a pathMatch: 'full', which is also satisfied as we have matched the whole URL (it had a single empty segment).
3. A redirect to welcome happens and the application renders WelcomeComponent.

What if there was no pathMatch: 'full'?

Actually, one would expect the whole thing to behave exactly the same. However, Angular explicitly prevents such a configuration ({ path: '', redirectTo: 'welcome' }) because if you put this Route above welcome, it would theoretically create an endless loop of redirects. So Angular just throws an error, which is why the application would not work at all! (https://angular.io/api/router/Route#pathMatch)

Actually, this does not make too much sense to me because Angular also has implemented a protection against such endless redirects - it only runs a single redirect per routing level! This would stop all further redirects (as you'll see in the example below).

What about path: '**'?

path: '**' will match absolutely anything (af/frewf/321532152/fsa is a match) with or without a pathMatch: 'full'.

Also, since it matches everything, the root path is also included, which makes { path: '', redirectTo: 'welcome' } completely redundant in this setup.

Funnily enough, it is perfectly fine to have this configuration:

const routes: Routes = [
  {
    path: '**',
    redirectTo: 'welcome'
  },
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
];

If we navigate to /welcome, path: '**' will be a match and a redirect to welcome will happen. Theoretically this should kick off an endless loop of redirects but Angular stops that immediately (because of the protection I mentioned earlier) and the whole thing works just fine.

And change the Version Code and Name from there.

Make sure IIS is listening to your port.

In my case this was the issue. So I had to change my port to something else like 8083 and it solved this issue.

**Solution which worked for me
Use NestedScrollView with height as wrap_content

<br> RecyclerView 
                android:layout_width="match_parent"<br>
                android:layout_height="wrap_content"<br>
                android:nestedScrollingEnabled="false"<br>
                  app:layoutManager="android.support.v7.widget.LinearLayoutManager"
                tools:targetApi="lollipop"<br><br> and view holder layout 
 <br> android:layout_width="match_parent"<br>
        android:layout_height="wrap_content"

//Your row content goes here

Don't try to scan text with nextLine(); AFTER using nextInt() with the same scanner! It doesn't work well with Java Scanner, and many Java developers opt to just use another Scanner for integers. You can call these scanners scan1 and scan2 if you want.

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

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

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

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

DPLYR makes this really easy.

x<-santa%>%
   count(Believe)

If you wanted to count by a group; for instance, how many males v females believe, just add a group_by:

x<-santa%>%
   group_by(Gender)%>%
   count(Believe)

You need to use a ServerSocket. You can find an explanation here.

When I started learning Spring Security, then I overrided the method userDetailsService() as in below code snippet:

@Configuration
@EnableWebSecurity
public class ApplicationSecurityConfiguration extends WebSecurityConfigurerAdapter{

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authorizeRequests()
                .antMatchers("/", "/index").permitAll()
                .anyRequest().authenticated()
                .and()
                .httpBasic();
    }

    @Override
    @Bean
    public UserDetailsService userDetailsService() {
        List<UserDetails> users= new ArrayList<UserDetails>();
        users.add(User.withDefaultPasswordEncoder().username("admin").password("nimda").roles("USER","ADMIN").build());
        users.add(User.withDefaultPasswordEncoder().username("Spring").password("Security").roles("USER").build());
        return new InMemoryUserDetailsManager(users);
    }
}

So we can log in to the application using the above-mentioned creds. (e.g. admin/nimda)

Note: This we should not use in production.

I think it is more pythonic:

aList.remove(123)
aList.insert(0, 2014)

more useful:

def shuffle(list, to_delete, to_shuffle, index):
    list.remove(to_delete)
    list.insert(index, to_shuffle)
    return

list = ['a', 'b']
shuffle(list, 'a', 'c', 0)
print list
>> ['c', 'b']

I have used clipboard.js.

We can get it on npm:

npm install clipboard --save

And also on Bower

bower install clipboard --save

Usage & examples are at https://zenorocha.github.io/clipboard.js/.

when we call ASCII as 7 bit code, the left most bit is used as sign bit so with 7 bits we can write up to 127. that means from -126 to 127 because Max imam value of ASCII is 0 to 255. this can be only satisfied with the argument of 7 bit if last bit is considered as sign bit

Using Babel (5.8) I get the same error if I try to use the expression export default in combination with some other export:

export const foo = "foo"
export const bar = "bar"
export default function baz() {}

This is an older question with a proper answer (please use parameterized queries) which I'd like to extend with some timezone discussion. For my current project I was interested in how do the datetime columns handle timezones and this question is the one I found.

Turns out, they do not, at all.

datetime column stores the given DateTime as is, without any conversion. It does not matter if the given datetime is UTC or local.

You can see for yourself:

using (var connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (var command = connection.CreateCommand())
    {
        command.CommandText = "SELECT * FROM (VALUES (@a, @b, @c)) example(a, b, c);";

        var local = DateTime.Now;
        var utc = local.ToUniversalTime();

        command.Parameters.AddWithValue("@a", utc);
        command.Parameters.AddWithValue("@b", local);
        command.Parameters.AddWithValue("@c", utc.ToLocalTime());

        using (var reader = command.ExecuteReader())
        {
            reader.Read();

            var localRendered = local.ToString("o");

            Console.WriteLine($"a = {utc.ToString("o").PadRight(localRendered.Length, ' ')} read = {reader.GetDateTime(0):o}, {reader.GetDateTime(0).Kind}");
            Console.WriteLine($"b = {local:o} read = {reader.GetDateTime(1):o}, {reader.GetDateTime(1).Kind}");
            Console.WriteLine($"{"".PadRight(localRendered.Length + 4, ' ')} read = {reader.GetDateTime(2):o}, {reader.GetDateTime(2).Kind}");
        }
    }
}

What this will print will of course depend on your time zone but most importantly the read values will all have Kind = Unspecified. The first and second output line will be different by your timezone offset. Second and third will be the same. Using the "o" format string (roundtrip) will not show any timezone specifiers for the read values.

Example output from GMT+02:00:

a = 2018-11-20T10:17:56.8710881Z      read = 2018-11-20T10:17:56.8700000, Unspecified
b = 2018-11-20T12:17:56.8710881+02:00 read = 2018-11-20T12:17:56.8700000, Unspecified
                                      read = 2018-11-20T12:17:56.8700000, Unspecified

Also note of how the data gets truncated (or rounded) to what seems like 10ms.

Looks like you need the package from the installation media if you're you're offline (located at D:\sources\sxs) You could copy this to each machine that you require .NET 3.5 on (so technically you only need the installation media once to get the package) and get each machine to run the command:

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess

There's a guide on MSDN.

You can use cluster module. Check this.

var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
    // Fork workers.
    for (var i = 0; i < numCPUs; i++) {
        cluster.fork();
    }

    cluster.on('exit', function(worker, code, signal) {
        console.log('worker ' + worker.process.pid + ' died');
    });
} else {
    // Workers can share any TCP connection
    // In this case its a HTTP server
    http.createServer(function(req, res) {
        res.writeHead(200);
        res.end("hello world\n");
    }).listen(8000);
}

Late to the game, but here's a powerful HOC pattern for overriding a component by providing it as a prop. It's simple and elegant.

Suppose MyComponent renders a fictional A component but you want to allow for a custom override of A, in this example B, which wraps A in a <div>...</div> and also appends "!" to the text prop:

import A from 'fictional-tooltip';

const MyComponent = props => (
  <props.A text="World">Hello</props.A>
);
MyComponent.defaultProps = { A };

const B = props => (
  <div><A {...props} text={props.text + '!'}></div>
);

ReactDOM.render(<MyComponent A={B}/>);

One of the best things about unit testing is that your code will become easier to test as you do it. Preexisting code created without tests is always a challenge because since they weren't meant to be unit-tested, it's not rare to have a high level of coupling between classes, hard-to-configure objects inside your class - like an e-mail sending service reference - and so on. But don't let this bring you down! You'll see that your overall code design will become better as you start to write unit-tests, and the more you test, the more confident you'll become on making even more changes to it without fear of breaking you application or introducing bugs.

There are several reasons to unit-test your code, but as time progresses, you'll find out that the time you save on testing is one of the best reasons to do it. In a system I've just delivered, I insisted on doing automated unit-testing in spite of the claims that I'd spend way more time doing the tests than I would by testing the system manually. With all my unit tests done, I run more than 400 test cases in less than 10 minutes, and every time I had to do a small change in the code, all it took me to be sure the code was still working without bugs was ten minutes. Can you imagine the time one would spend to run those 400+ test cases by hand?

When it comes to automated testing - be it unit testing or acceptance testing - everyone thinks it's a wasted effort to code what you can do manually, and sometimes it's true - if you plan to run your tests only once. The best part of automated testing is that you can run them several times without effort, and after the second or third run, the time and effort you've wasted is already paid for.

One last piece of advice would be to not only unit test your code, but start doing test first (see TDD and BDD for more)

There really isn't a need to do this unless you insist on the value of 0. The HtmlHelper DropDownList extension allows you to set an option label that shows up as the initial value in the select with a null value. Simply use one of the DropDownList signatures that has the option label.

<%= Html.DropDownList( "DropDownValue",
                       (IEnumerable<SelectListItem>)ViewData["Menu"],
                        "-- Select One --" ) %>

Check out my highly simplified Echo example: It is designed to use basic HTTP communication, but it can easily be modified to use named pipes by editing the app.config files for the client and server. Make the following changes:

Edit the server's app.config file, removing or commenting out the http baseAddress entry and adding a new baseAddress entry for the named pipe (called net.pipe). Also, if you don't intend on using HTTP for a communication protocol, make sure the serviceMetadata and serviceDebug is either commented out or deleted:

<configuration>
    <system.serviceModel>
        <services>
            <service name="com.aschneider.examples.wcf.services.EchoService">
                <host>
                    <baseAddresses>
                        <add baseAddress="net.pipe://localhost/EchoService"/>
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors></serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

Edit the client's app.config file so that the basicHttpBinding is either commented out or deleted and a netNamedPipeBinding entry is added. You will also need to change the endpoint entry to use the pipe:

<configuration>
    <system.serviceModel>
        <bindings>
            <netNamedPipeBinding>
                <binding name="NetNamedPipeBinding_IEchoService"/>
            </netNamedPipeBinding>
        </bindings>
        <client>
            <endpoint address              = "net.pipe://localhost/EchoService"
                      binding              = "netNamedPipeBinding"
                      bindingConfiguration = "NetNamedPipeBinding_IEchoService"
                      contract             = "EchoServiceReference.IEchoService"
                      name                 = "NetNamedPipeBinding_IEchoService"/>
        </client>
    </system.serviceModel>
</configuration>

The above example will only run with named pipes, but nothing is stopping you from using multiple protocols to run your service. AFAIK, you should be able to have a server run a service using both named pipes and HTTP (as well as other protocols).

Also, the binding in the client's app.config file is highly simplified. There are many different parameters you can adjust, aside from just specifying the baseAddress...

Here is an approach for you to do something on a different thread and start listening to the key pressed in a different thread. And the Console will stop its processing when your actual process ends or the user terminates the process by pressing Esc key.

class SplitAnalyser
{
    public static bool stopProcessor = false;
    public static bool Terminate = false;

    static void Main(string[] args)
    {
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("Split Analyser starts");
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("Press Esc to quit.....");
        Thread MainThread = new Thread(new ThreadStart(startProcess));
        Thread ConsoleKeyListener = new Thread(new ThreadStart(ListerKeyBoardEvent));
        MainThread.Name = "Processor";
        ConsoleKeyListener.Name = "KeyListener";
        MainThread.Start();
        ConsoleKeyListener.Start();

        while (true) 
        {
            if (Terminate)
            {
                Console.WriteLine("Terminating Process...");
                MainThread.Abort();
                ConsoleKeyListener.Abort();
                Thread.Sleep(2000);
                Thread.CurrentThread.Abort();
                return;
            }

            if (stopProcessor)
            {
                Console.WriteLine("Ending Process...");
                MainThread.Abort();
                ConsoleKeyListener.Abort();
                Thread.Sleep(2000);
                Thread.CurrentThread.Abort();
                return;
            }
        } 
    }

    public static void ListerKeyBoardEvent()
    {
        do
        {
            if (Console.ReadKey(true).Key == ConsoleKey.Escape)
            {
                Terminate = true;
            }
        } while (true); 
    }

    public static void startProcess()
    {
        int i = 0;
        while (true)
        {
            if (!stopProcessor && !Terminate)
            {
                Console.ForegroundColor = ConsoleColor.White;
                Console.WriteLine("Processing...." + i++);
                Thread.Sleep(3000);
            }
            if(i==10)
                stopProcessor = true;

        }
    }

}

Collections.singletonList(object)

the list created by this method is immutable.

JToken is the base class for JObject, JArray, JProperty, JValue, etc. You can use the Children<T>() method to get a filtered list of a JToken's children that are of a certain type, for example JObject. Each JObject has a collection of JProperty objects, which can be accessed via the Properties() method. For each JProperty, you can get its Name. (Of course you can also get the Value if desired, which is another JToken.)

Putting it all together we have:

JArray array = JArray.Parse(json);

foreach (JObject content in array.Children<JObject>())
{
    foreach (JProperty prop in content.Properties())
    {
        Console.WriteLine(prop.Name);
    }
}

Output:

Here is what you do in Excel 2003:

1. In your sheet of interest, go to Format -> Sheet -> Hide and hide your sheet.
2. Go to Tools -> Protection -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Here is what you do in Excel 2007:

1. In your sheet of interest, go to Home ribbon -> Format -> Hide & Unhide -> Hide Sheet and hide your sheet.
2. Go to Review ribbon -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?

If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.

Although this question has been asked a while ago, it is still relevant as of today. This is not a trivial approach using script file params, but I already had some extreme use-cases that this way was most suited.

I came across this post to find out a better solution than I wrote a while ago, with hope to find maybe a native feature or something similar.
I will share my solution, up until a better one will be implemented. This works on most modern browsers, maybe even on older ones, didn't try.

All the solutions above, are based on the fact that it has to be injected with predefined and well marked SCRIPT tag and rely completely on the HTML implementation. But, what if the script is injected dynamically, or even worse, what if you are write a library, that will be used in a variety of websites?
In these and some other cases, all the above answers are not sufficient and even becoming too complicated.

First, let's try to understand what do we need to achieve here. All we need to do is to get the URL of the script itself, from there it's a piece of cake.

There is actually a nice trick to get the script URL from the script itself. One of the functionalities of the native Error class, is the ability to provide a stack trace of the "problematic location", including the exact file trace to the last call. In order to achieve this, I will use the stack property of the Error instance, that once created, will give the full stack trace.

Here is how the magic works:

// The pattern to split each row in the stack trace string
const STACK_TRACE_SPLIT_PATTERN = /(?:Error)?\n(?:\s*at\s+)?/;
// For browsers, like Chrome, IE, Edge and more.
const STACK_TRACE_ROW_PATTERN1 = /^.+?\s\((.+?):\d+:\d+\)$/;
// For browsers, like Firefox, Safari, some variants of Chrome and maybe other browsers.
const STACK_TRACE_ROW_PATTERN2 = /^(?:.*?@)?(.*?):\d+(?::\d+)?$/;

const getFileParams = () => {
    const stack = new Error().stack;
    const row = stack.split(STACK_TRACE_SPLIT_PATTERN, 2)[1];
    const [, url] = row.match(STACK_TRACE_ROW_PATTERN1) || row.match(STACK_TRACE_ROW_PATTERN2) || [];
    if (!url) {
        console.warn("Something went wrong. You should debug it and find out why.");
        return;
    }
    try {
        const urlObj = new URL(url);
        return urlObj.searchParams; // This feature doesn't exists in IE, in this case you should use urlObj.search and handle the query parsing by yourself.
    } catch (e) {
        console.warn(`The URL '${url}' is not valid.`);
    }
}

Now, in any case of script call, like in the OP case:

<script type="text/javascript" src="file.js?obj1=somevalue&obj2=someothervalue"></script>

In the file.js script, you can now do:

const params = getFileParams();
console.log(params.get('obj2'));
// Prints: someothervalue

This will also work with RequireJS and other dynamically injected file scripts.

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

Well, you do have to create a temp table, but it doesn't have to have the right schema....I've created a stored procedure that modifies an existing temp table so that it has the required columns with the right data type and order (dropping all existing columns, adding new columns):

GO
create procedure #TempTableForSP(@tableId int, @procedureId int)  
as   
begin  
    declare @tableName varchar(max) =  (select name  
                                        from tempdb.sys.tables 
                                        where object_id = @tableId
                                        );    
    declare @tsql nvarchar(max);    
    declare @tempId nvarchar(max) = newid();      
    set @tsql = '    
    declare @drop nvarchar(max) = (select  ''alter table tempdb.dbo.' + @tableName 
            +  ' drop column ''  + quotename(c.name) + '';''+ char(10)  
                                   from tempdb.sys.columns c   
                                   where c.object_id =  ' + 
                                         cast(@tableId as varchar(max)) + '  
                                   for xml path('''')  
                                  )    
    alter table tempdb.dbo.' + @tableName + ' add ' + QUOTENAME(@tempId) + ' int;
    exec sp_executeSQL @drop;    
    declare @add nvarchar(max) = (    
                                select ''alter table ' + @tableName 
                                      + ' add '' + name 
                                      + '' '' + system_type_name 
                           + case when d.is_nullable=1 then '' null '' else '''' end 
                                      + char(10)   
                              from sys.dm_exec_describe_first_result_set_for_object(' 
                               + cast(@procedureId as varchar(max)) + ', 0) d  
                                order by column_ordinal  
                                for xml path(''''))    

    execute sp_executeSQL  @add;    
    alter table '  + @tableName + ' drop column ' + quotename(@tempId) + '  ';      
    execute sp_executeSQL @tsql;  
end         
GO

create table #exampleTable (pk int);

declare @tableId int = object_Id('tempdb..#exampleTable')
declare @procedureId int = object_id('examplestoredProcedure')

exec #TempTableForSP @tableId, @procedureId;

insert into #exampleTable
exec examplestoredProcedure

Note this won't work if sys.dm_exec_describe_first_result_set_for_object can't determine the results of the stored procedure (for instance if it uses a temp table).

Often you want to pass a viewmodel also, and not the only one file. In the code below you'll find some other useful features:

• checking if the file has been attached
• checking if file size is 0
• checking if file size is above 4 MB
• checking if file size is less than 100 bytes
• checking file extensions

It could be done via the following code:

[HttpPost]
public ActionResult Index(MyViewModel viewModel)
{
    // if file's content length is zero or no files submitted

    if (Request.Files.Count != 1 || Request.Files[0].ContentLength == 0)
    {
        ModelState.AddModelError("uploadError", "File's length is zero, or no files found");
        return View(viewModel);
    }

    // check the file size (max 4 Mb)

    if (Request.Files[0].ContentLength > 1024 * 1024 * 4)
    {
        ModelState.AddModelError("uploadError", "File size can't exceed 4 MB");
        return View(viewModel);
    }

    // check the file size (min 100 bytes)

    if (Request.Files[0].ContentLength < 100)
    {
        ModelState.AddModelError("uploadError", "File size is too small");
        return View(viewModel);
    }

    // check file extension

    string extension = Path.GetExtension(Request.Files[0].FileName).ToLower();

    if (extension != ".pdf" && extension != ".doc" && extension != ".docx" && extension != ".rtf" && extension != ".txt")
    {
        ModelState.AddModelError("uploadError", "Supported file extensions: pdf, doc, docx, rtf, txt");
        return View(viewModel);
    }

    // extract only the filename
    var fileName = Path.GetFileName(Request.Files[0].FileName);

    // store the file inside ~/App_Data/uploads folder
    var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);

    try
    {
        if (System.IO.File.Exists(path))
            System.IO.File.Delete(path);

        Request.Files[0].SaveAs(path);
    }
    catch (Exception)
    {
        ModelState.AddModelError("uploadError", "Can't save file to disk");
    }

    if(ModelState.IsValid)
    {
        // put your logic here

        return View("Success");
    }

    return View(viewModel);         
}

Make sure you have

@Html.ValidationMessage("uploadError")

in your view for validation errors.

Also keep in mind that default maximum request length is 4MB (maxRequestLength = 4096), to upload larger files you have to change this parameter in web.config:

<system.web>
    <httpRuntime maxRequestLength="40960" executionTimeout="1100" />

(40960 = 40 MB here).

Execution timeout is the whole number of seconds. You may want to change it to allow huge files uploads.

eval('(' + jsonObject + ')')

Just match /^index\.php/ then reject whatever matches it.

Ensure Solution Explorer is visible In MS Studio 2008 Go to view and click Solution explorer

In Solution explorer go to Reference Right click on Reference and select Add Reference.. Select .NET tab Scroll down till you find System.Drawing -> select it -> click on OK button Do the same for System.Windows.Forms

When you run your form this will work

I solved this by changing transports from 'websocket' to 'polling'

   var socket = io.connect('xxx.xxx.xxx.xxx:8000', {
      transports: ['polling']
   });

It's very similar to

char array[] = {'O', 'n', 'e', ' ', /*etc*/ ' ', 'm', 'u', 's', 'i', 'c', '\0'};

but gives you read-only memory.

For a discussion of the difference between a char[] and a char *, see comp.lang.c FAQ 1.32.

You need to write it this way

<div 
    className="player"
    style={{ position: "absolute" }}
    onKeyDown={this.onKeyPressed}
    tabIndex="0"
  >

If onKeyPressed is not bound to this, then try to rewrite it using arrow function or bind it in the component constructor.

To get the namespace in its namespace format, e.g. {myNameSpace}, you can do the following:

root = tree.getroot()
ns = re.match(r'{.*}', root.tag).group(0)

This way, you can use it later on in your code to find nodes, e.g using string interpolation (Python 3).

link = root.find(f"{ns}link")

table {
    width: 100%;

    th, td {
        width: 1%;
    }
}

SCSS syntax

The URI is encoded as UTF-8, but Tomcat is decoding them as ISO-8859-1. You need to edit the connector settings in the server.xml and add the URIEncoding="UTF-8" attribute.

or edit this parameter on your application.properties

server.tomcat.uri-encoding=utf-8

Basically, to make a cross domain AJAX requests, the requested server should allow the cross origin sharing of resources (CORS). You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/

In your scenario, you are setting the headers in the client which in fact needs to be set into http://localhost:8080/app server side code.

If you are using PHP Apache server, then you will need to add following in your .htaccess file:

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

Joshua P Nixon's answer is correct but I had to set last modified date also. so here is the code.

var file = new File([blob], "file_name", {lastModified: 1534584790000});

1534584790000 is an unix timestamp for "GMT: Saturday, August 18, 2018 9:33:10 AM"

Here's proof that using std::numeric_limits::epsilon() is not the answer — it fails for values greater than one:

Proof of my comment above:

#include <stdio.h>
#include <limits>

double ItoD (__int64 x) {
    // Return double from 64-bit hexadecimal representation.
    return *(reinterpret_cast<double*>(&x));
}

void test (__int64 ai, __int64 bi) {
    double a = ItoD(ai), b = ItoD(bi);
    bool close = std::fabs(a-b) < std::numeric_limits<double>::epsilon();
    printf ("%.16f and %.16f %s close.\n", a, b, close ? "are " : "are not");
}

int main()
{
    test (0x3fe0000000000000L,
          0x3fe0000000000001L);

    test (0x3ff0000000000000L,
          0x3ff0000000000001L);
}

Running yields this output:

0.5000000000000000 and 0.5000000000000001 are  close.
1.0000000000000000 and 1.0000000000000002 are not close.

Note that in the second case (one and just larger than one), the two input values are as close as they can possibly be, and still compare as not close. Thus, for values greater than 1.0, you might as well just use an equality test. Fixed epsilons will not save you when comparing floating-point values.

There's always LINQ:

t.GetProperties().Where(
    p=>p.GetCustomAttributes(typeof(MyAttribute), true).Length != 0)

You can use the isNaN function to determine if a value does not convert to a number. Example as below:

function checkInp()
{
  var x=document.forms["myForm"]["age"].value;
  if (isNaN(x)) 
  {
    alert("Must input numbers");
    return false;
  }
}

Apple released code at WWDC as a category on UIImage that includes this functionality, if you have a developer account you can grab the UIImage category (and the rest of the sample code) by going to this link: https://developer.apple.com/wwdc/schedule/ and browsing for section 226 and clicking on details. I haven't played around with it yet but I think the effect will be a lot slower on iOS 6, there are some enhancements to iOS 7 that make grabbing the initial screen shot that is used as input to the blur a lot faster.

If you want many inserts

from rope.base.codeanalyze import ChangeCollector

c = ChangeCollector(code)
c.add_change(5, 5, '<span style="background-color:#339999;">')
c.add_change(10, 10, '</span>')
rend_code = c.get_changed()

This works for me perfectly without any external API, just native Java hidden feature :)

import com.sun.management.OperatingSystemMXBean;
...
OperatingSystemMXBean osBean = ManagementFactory.getPlatformMXBean(
                OperatingSystemMXBean.class);
// What % CPU load this current JVM is taking, from 0.0-1.0
System.out.println(osBean.getProcessCpuLoad());

// What % load the overall system is at, from 0.0-1.0
System.out.println(osBean.getSystemCpuLoad());

If you want to mirror same content from source to destination, try following one.

function CopyFilesToFolder ($fromFolder, $toFolder) {
    $childItems = Get-ChildItem $fromFolder
    $childItems | ForEach-Object {
         Copy-Item -Path $_.FullName -Destination $toFolder -Recurse -Force
    }
}

Test:

CopyFilesToFolder "C:\temp\q" "c:\temp\w"

For me it works like this

Rotate clockwise

 ffmpeg -i "path_source_video.mp4" -filter:v "transpose=1" "path_output_video.mp4"

Rotate counterclockwise

 ffmpeg -i "path_source_video.mp4" -filter:v "transpose=0,transpose=1,transpose=0" -acodec copy "path_output_video.mp4"

the package I use zeranoe

Look at a JUnit report. JUnit is already organized by package. Each package has (or can have) TestSuite classes, each of which in turn run multiple TestCases. Each TestCase can have multiple test methods of the form public void test*(), each of which will actually become an instance of the TestCase class to which they belong. Each test method (TestCase instance) has a name and a pass/fail criteria.

What my management requires is the concept of individual TestStep items, each of which reports their own pass/fail criteria. Failure of any test step must not prevent the execution of subsequent test steps.

In the past, test developers in my position organized TestCase classes into packages that correspond to the part(s) of the product under test, created a TestCase class for each test, and made each test method a separate "step" in the test, complete with its own pass/fail criteria in the JUnit output. Each TestCase is a standalone "test", but the individual methods, or test "steps" within the TestCase, must occur in a specific order.

The TestCase methods were the steps of the TestCase, and test designers got a separate pass/fail criterion per test step. Now the test steps are jumbled, and the tests (of course) fail.

For example:

Class testStateChanges extends TestCase

public void testCreateObjectPlacesTheObjectInStateA()
public void testTransitionToStateBAndValidateStateB()
public void testTransitionToStateCAndValidateStateC()
public void testTryToDeleteObjectinStateCAndValidateObjectStillExists()
public void testTransitionToStateAAndValidateStateA()
public void testDeleteObjectInStateAAndObjectDoesNotExist()
public void cleanupIfAnythingWentWrong()

Each test method asserts and reports its own separate pass/fail criteria. Collapsing this into "one big test method" for the sake of ordering loses the pass/fail criteria granularity of each "step" in the JUnit summary report. ...and that upsets my managers. They are currently demanding another alternative.

Can anyone explain how a JUnit with scrambled test method ordering would support separate pass/fail criteria of each sequential test step, as exemplified above and required by my management?

Regardless of the documentation, I see this as a serious regression in the JUnit framework that is making life difficult for lots of test developers.

Start a timer in the constructor of your class. The interval is in milliseconds so 5*60 seconds = 300 seconds = 300000 milliseconds.

static void Main(string[] args)
{
    System.Timers.Timer timer = new System.Timers.Timer();
    timer.Interval = 300000;
    timer.Elapsed += timer_Elapsed;
    timer.Start();
}

Then call GetData() in the timer_Elapsed event like this:

static void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    //YourCode
}

Try this as a shortcut, not as a definitive solution (see comments):

<script type="text/javascript">
    var ip = location.host;
    alert(ip);
</script>

This solution cannot work in some scenarios but it can help for quick testing. Regards

you can use script module

Example

- name: Transfer and execute a script.
  hosts: all
  tasks:

     - name: Copy and Execute the script 
       script: /home/user/userScript.sh

Look at strtok(). strtok() is not a re-entrant function.

strtok_r() is the re-entrant version of strtok(). Here's an example program from the manual:

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

   int main(int argc, char *argv[])
   {
       char *str1, *str2, *token, *subtoken;
       char *saveptr1, *saveptr2;
       int j;

       if (argc != 4) {
           fprintf(stderr, "Usage: %s string delim subdelim\n",argv[0]);
           exit(EXIT_FAILURE);
       }

       for (j = 1, str1 = argv[1]; ; j++, str1 = NULL) {
           token = strtok_r(str1, argv[2], &saveptr1);
           if (token == NULL)
               break;
           printf("%d: %s\n", j, token);

           for (str2 = token; ; str2 = NULL) {
               subtoken = strtok_r(str2, argv[3], &saveptr2);
               if (subtoken == NULL)
                   break;
               printf(" --> %s\n", subtoken);
           }
       }

       exit(EXIT_SUCCESS);
   }

Sample run which operates on subtokens which was obtained from the previous token based on a different delimiter:

$ ./a.out hello:word:bye=abc:def:ghi = :

1: hello:word:bye
 --> hello
 --> word
 --> bye
2: abc:def:ghi
 --> abc
 --> def
 --> ghi

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

ConfigurationManager.AppSettings is actually a property, so you need to use square brackets.

Overall, here's what you need to do:

SqlConnection con= new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);

The problem is that you tried to set con to a string, which is not correct. You have to either pass it to the constructor or set con.ConnectionString property.

This is what I use.

function getOrientation() {

    // if window.orientation is available...
    if( window.orientation && typeof window.orientation === 'number' ) {

        // ... and if the absolute value of orientation is 90...
        if( Math.abs( window.orientation ) == 90 ) {

              // ... then it's landscape
              return 'landscape';

        } else {

              // ... otherwise it's portrait
              return 'portrait';

        }

    } else {

        return false; // window.orientation not available

    }

}

Implementation

window.addEventListener("orientationchange", function() {

     // if orientation is landscape...
     if( getOrientation() === 'landscape' ) {

         // ...do your thing

    }

}, false);

I find that no one mentions this difference:

__getattribute__ has a default implementation, but __getattr__ does not.

class A:
    pass
a = A()
a.__getattr__ # error
a.__getattribute__ # return a method-wrapper

This has a clear meaning: since __getattribute__ has a default implementation, while __getattr__ not, clearly python encourages users to implement __getattr__.

The easiest way would be to use Runtime.getRuntime.exec().

For example, to get a registry value for the default browser on Windows:

String command = "REG QUERY HKEY_CLASSES_ROOT\\http\\shell\\open\\command";
try
{
    Process process = Runtime.getRuntime().exec(command);
} catch (IOException e)
{
    e.printStackTrace();
}

Then use a Scanner to get the output of the command, if necessary.

Scanner kb = new Scanner(process.getInputStream());

Note: the \ is an escape character in a String, and must be escaped to work properly (hence the \\).

However, there is no executable called cd, because it can't be implemented in a separate process.

The one case where the current working directory matters is executing an external process (using ProcessBuilder or Runtime.exec()). In those cases you can specify the working directory to use for the newly started process explicitly.

Easiest way for your command:

System.setProperty("user.dir", "C:\\Program Files\\Flowella");

If your div is absolutely positioned and you know the width, you can just use:

#myDiv{
position:absolute;
left: 0;
width: 200px;
}

$('#myDiv').animate({left:'-200'},1000);

Which will slide it off screen.

Alternatively, you could wrap it a container div

#myContainer{
position:relative;
width: 200px;
overflow: hidden;
}

#myDiv{
position:absolute;
top: 0;
left: 0;
width: 200px;
}

<div id="myContainer">

<div id="myDiv">Wheee!</div>

</div>

$('#myDiv').animate({left:'-200'},1000);

Since you add .. after cmake, it will jump up and up (just like cd ..) in the directory. But if you want to run cmake under the same folder with CMakeLists.txt, please use . instead of ...

I had a similar problem using Flask, but I did not have to resort to JSON. I just passed a list letters = ['a','b','c'] with render_template('show_entries.html', letters=letters), and set

var letters = {{ letters|safe }}

in my javascript code. Jinja2 replaced {{ letters }} with ['a','b','c'], which javascript interpreted as an array of strings.

MVC 4:

    function Cargar_BS(bs) {
        $.getJSON('@Url.Action("GetBienServicio", "MonitoreoAdministracion")',
                        {
                            id: bs
                        },
                        function (d) {
                            $("#txtIdItem").empty().append('<option value="">-Seleccione-</option>');
                            $.each(d, function (idx, item) {
                                jQuery("<option/>").text(item.C_DescBs).attr("value", item.C_CodBs).appendTo("#txtIdItem");
                            })
                            $('#txtIdItem').trigger("chosen:updated");
                        });
    }

Assuming you mean you want to do this automatically from a "local" machine, without manually logging into the "remote" machine, you should look into a TCL extension known as Expect, it is designed precisely for this sort of situation. I've also provided a link to a script for logging-in/interacting via SSH.

            echo $value;
        }
    }else{

An '@' has another meaning as well: putting it in front of a variable declaration allows you to use reserved keywords as variable names.

For example:

string @class = "something";
int @object = 1;

I've only found one or two legitimate uses for this. Mainly in ASP.NET MVC when you want to do something like this:

<%= Html.ActionLink("Text", "Action", "Controller", null, new { @class = "some_css_class" })%>

Which would produce an HTML link like:

<a href="/Controller/Action" class="some_css_class">Text</a>

Otherwise you would have to use 'Class', which isn't a reserved keyword but the uppercase 'C' does not follow HTML standards and just doesn't look right.

Globally install Composer on OS X 10.11 El Capitan

This command will NOT work in OS X 10.11:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/bin --filename=composer 

Instead, let's write to the /usr/local/bin path for the user:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Now we can access the composer command globally, just like before.

It's better to use backtracking

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

void swap(char *a, char *b) {
    char temp;
    temp = *a;
    *a = *b;
    *b = temp;
}

void print(char *a, int i, int n) {
    int j;
    if(i == n) {
        printf("%s\n", a);
    } else {
        for(j = i; j <= n; j++) {
            swap(a + i, a + j);
            print(a, i + 1, n);
            swap(a + i, a + j);
        }
    }
}

int main(void) {
    char a[100];
    gets(a);
    print(a, 0, strlen(a) - 1);
    return 0;
}

With little modification but almost similar approach to get the full file path of each sub folder

dataFolderPath = 'UCR_TS_Archive_2015/';

dirData = dir(dataFolderPath);      %# Get the data for the current directory
dirIndex = [dirData.isdir];  %# Find the index for directories
fileList = {dirData(~dirIndex).name}';  %'# Get a list of the files
if ~isempty(fileList)
    fileList = cellfun(@(x) fullfile(dataFolderPath,x),...  %# Prepend path to files
        fileList,'UniformOutput',false);
end
subDirs = {dirData(dirIndex).name};  %# Get a list of the subdirectories
validIndex = ~ismember(subDirs,{'.','..'});  %# Find index of subdirectories
%#   that are not '.' or '..'
for iDir = find(validIndex)                  %# Loop over valid subdirectories
    nextDir = fullfile(dataFolderPath,subDirs{iDir});    %# Get the subdirectory path
    getAllFiles = dir(nextDir);
    for k = 1:1:size(getAllFiles,1)
        validFileIndex = ~ismember(getAllFiles(k,1).name,{'.','..'});
        if(validFileIndex)
            filePathComplete = fullfile(nextDir,getAllFiles(k,1).name);
            fprintf('The Complete File Path: %s\n', filePathComplete);
        end
    end
end  

To be more clear, I will begin at the beginning.

I will rely on the sample code found in https://github.com/ExcelDataReader/ExcelDataReader, but with some modifications to avoid inconveniences.

The following code detects the file format, either xls or xlsx.

FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader;

//1. Reading Excel file
if (Path.GetExtension(filePath).ToUpper() == ".XLS")
{
    //1.1 Reading from a binary Excel file ('97-2003 format; *.xls)
    excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
}
else
{
    //1.2 Reading from a OpenXml Excel file (2007 format; *.xlsx)
    excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
}

//2. DataSet - The result of each spreadsheet will be created in the result.Tables
DataSet result = excelReader.AsDataSet();

//3. DataSet - Create column names from first row
excelReader.IsFirstRowAsColumnNames = false;

Now we can access the file contents in a more convenient way. I use DataTable for this. The following is an example to access a specific cell, and print its value in the console:

DataTable dt = result.Tables[0];
Console.WriteLine(dt.Rows[rowPosition][columnPosition]);

If you do not want to do a DataTable, you can do the same as follows:

Console.WriteLine(result.Tables[0].Rows[rowPosition][columnPosition]);

It is important not try to read beyond the limits of the table, for this you can see the number of rows and columns as follows:

Console.WriteLine(result.Tables[0].Rows.Count);
Console.WriteLine(result.Tables[0].Columns.Count);

Finally, when you're done, you should close the reader and free resources:

//5. Free resources (IExcelDataReader is IDisposable)
excelReader.Close();

I hope you find it useful.

(I understand that the question is old, but I make this contribution to enhance the knowledge base, because there is little material about particular implementations of this library).

The method .appendChild() is used to add a new element NOT add text to an existing element.

Example:

var p = document.createElement("p");
document.body.appendChild(p);

Reference: Mozilla Developer Network

The standard approach for this is using .innerHTML(). But if you want a alternate solution you could try using element.textContent.

Example:

document.getElementById("foo").textContent = "This is som text";

Reference: Mozilla Developer Network

How ever this is only supported in IE 9+

You can use the following code snippet :

java -XX:+PrintFlagsFinal -Xms512m -Xmx1024m -Xss512k -XX:PermSize=64m -XX:MaxPermSize=128m
    -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

In my pc I am getting following output :

    uintx InitialHeapSize                          := 536870912       {product}
    uintx MaxHeapSize                              := 1073741824      {product}
    uintx PermSize                                 := 67108864        {pd product}
    uintx MaxPermSize                              := 134217728       {pd product}
     intx ThreadStackSize                          := 512             {pd product}

On IntelliJ IDEA 2016.1.2

Go to Settings > Editor > General > Appearance then check the Show Line number option

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

instead of using iframe and depending on the third party`think about using flexpaper, or pdf.js.

I used PDF.js, it works fine for me. Here is the demo.

The best/easy/fast solution that you can use if it's a quick debugging, is to surround your code with catching exceptions. That's what I'm doing when I want to check something fast in production.

try {
    // Page code
}
catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

Use this code:

shell_exec("wmic computersystem get username")

Maybe you should try it with -quality 100 -size "1024x1024", because resize often gives results that are ugly to view.

You should override Equals and GetHashCode meaningfully, in this case to compare the ID:

public class LinqTest
{
    public int id { get; set; }
    public string value { get; set; }

    public override bool Equals(object obj)
    {
        LinqTest obj2 = obj as LinqTest;
        if (obj2 == null) return false;
        return id == obj2.id;
    }

    public override int GetHashCode()
    {
        return id;
    }
}

Now you can use Distinct:

List<LinqTest> uniqueIDs = myList.Distinct().ToList();

'&' --> '&'

'<' --> '&lt;'

'>' --> '&gt;'

On Windows:

CHDIR Displays the name of or changes the current directory.

In Linux:

PWD Displays the name of current directory.

Since $.getJSON is async, I think your console.log(list.length); code is firing before your array has been populated. To correct this put your console.log statement inside your callback:

var list = new Array();
$.getJSON("json.js", function(data) {
    $.each(data, function(i, item) {
        console.log(item.text);
        list.push(item.text);
    });
    console.log(list.length);
});

The examples below refer to the following HTML snippet:

<div id="test">
   Warning: This element contains <code>code</code> and <strong>strong language</strong>.
</div>

The node will be referenced by the following JavaScript:

var x = document.getElementById('test');

element.innerHTML

Sets or gets the HTML syntax describing the element's descendants

x.innerHTML
// => "
// =>   Warning: This element contains <code>code</code> and <strong>strong language</strong>.
// => "

This is part of the W3C's DOM Parsing and Serialization Specification. Note it's a property of Element objects.

node.innerText

Sets or gets the text between the start and end tags of the object

x.innerText
// => "Warning: This element contains code and strong language."

• innerText was introduced by Microsoft and was for a while unsupported by Firefox. In August of 2016, innerText was adopted by the WHATWG and was added to Firefox in v45.
• innerText gives you a style-aware, representation of the text that tries to match what's rendered in by the browser this means:
  • innerText applies text-transform and white-space rules
  • innerText trims white space between lines and adds line breaks between items
  • innerText will not return text for invisible items
• innerText will return textContent for elements that are never rendered like <style /> and `
• Property of Node elements

node.textContent

Gets or sets the text content of a node and its descendants.

x.textContent
// => "
// =>   Warning: This element contains code and strong language.
// => "

While this is a W3C standard, it is not supported by IE < 9.

• Is not aware of styling and will therefore return content hidden by CSS
• Does not trigger a reflow (therefore more performant)
• Property of Node elements

node.value

This one depends on the element that you've targeted. For the above example, x returns an HTMLDivElement object, which does not have a value property defined.

x.value // => null

Input tags (<input />), for example, do define a value property, which refers to the "current value in the control".

<input id="example-input" type="text" value="default" />
<script>
  document.getElementById('example-input').value //=> "default"
  // User changes input to "something"
  document.getElementById('example-input').value //=> "something"
</script>

From the docs:

Note: for certain input types the returned value might not match the value the user has entered. For example, if the user enters a non-numeric value into an <input type="number">, the returned value might be an empty string instead.

Sample Script

Here's an example which shows the output for the HTML presented above:

var properties = ['innerHTML', 'innerText', 'textContent', 'value'];_x000D_
_x000D_
// Writes to textarea#output and console_x000D_
function log(obj) {_x000D_
  console.log(obj);_x000D_
  var currValue = document.getElementById('output').value;_x000D_
  document.getElementById('output').value = (currValue ? currValue + '\n' : '') + obj; _x000D_
}_x000D_
_x000D_
// Logs property as [propName]value[/propertyName]_x000D_
function logProperty(obj, property) {_x000D_
  var value = obj[property];_x000D_
  log('[' + property + ']'  +  value + '[/' + property + ']');_x000D_
}_x000D_
_x000D_
// Main_x000D_
log('=============== ' + properties.join(' ') + ' ===============');_x000D_
for (var i = 0; i < properties.length; i++) {_x000D_
  logProperty(document.getElementById('test'), properties[i]);_x000D_
}

<div id="test">_x000D_
  Warning: This element contains <code>code</code> and <strong>strong language</strong>._x000D_
</div>_x000D_
<textarea id="output" rows="12" cols="80" style="font-family: monospace;"></textarea>

You may also use the defer attribute in the script tag. As long as you do not specify async which would of course not be useful for your aim.

Example:

<script src="//other-domain.com/script.js" defer></script>
<script src="myscript.js" defer></script>

As described here:

In the above example, the browser will download both scripts in parallel and execute them just before DOMContentLoaded fires, maintaining their order.

[...] deferred scripts should run after the document had parsed, in the order they were added [...]

i solved this problem by changing jre required for server (in my case is tomcat). From Server tab in eclipse, double click on the server (in order to open page for server configuration), click on Runtime environment, then change JRE required

It looks like others had this problem also, and there is a simple Python script now, for converting output of mysqldump into CSV files.

wget https://raw.githubusercontent.com/jamesmishra/mysqldump-to-csv/master/mysqldump_to_csv.py
mysqldump -u username -p --host=rdshostname database table | python mysqldump_to_csv.py > table.csv

I will leave this here as a possible fix, worked for me at least and might help others. Pretty sure this would be a linux only fix.

I decided to not go with the pip install and go with the github version (option one on the installation guide).

Instead of placing the copied docker-compose directory into /usr/local/bin/docker-compose from the curl/github command, I went with /usr/bin/docker-compose which is the location of Docker itself and will force the program to run in root. So it works in root and sudo but now won't work without sudo so the opposite effect which is what you want to run it as a user anyways.

How to get the version {major}.{year}.1{date}.1{time}

This one is kind of experimental, but I like it. Inspired by Jeff Atwood @ CodingHorror (link).

The resulting version number becomes 1.2016.10709.11641 (meaning 2016-07-09 16:41), which allows for

• poor mans zero padding (with the stupid leading 1s)
• nearly-human readable local DateTime embedded into the version number
• leaving Major version alone for really major breaking changes.

Add a new item to your project, select General -> Text Template, name it something like CustomVersionNumber and (where applicable) comment out the AssemblyVersion and AssemblyFileVersion in Properties/AssemblyInfo.cs.

Then, when saving this file, or building the project, this will regenerate a .cs file located as a sub-item under the created .tt file.

<#@ template language="C#" #>
<#@ assembly name="System.Core" #>
<#@ import namespace="System.Linq" #>

//
// This code was generated by a tool. Any changes made manually will be lost
// the next time this code is regenerated.
//

using System.Reflection;

<#
    var date = DateTime.Now;
    int major = 1;
    int minor = date.Year;
    int build = 10000 + int.Parse(date.ToString("MMdd"));
    int revision = 10000 + int.Parse(date.ToString("HHmm"));
#>

[assembly: AssemblyVersion("<#= $"{major}.{minor}.{build}.{revision}" #>")]
[assembly: AssemblyFileVersion("<#= $"{major}.{minor}.{build}.{revision}" #>")]

In my case, I was installing a project with MinimumSDK bigger than the Android version of my real device. I used another device and it solved MinSDK -> 24 My Phone -> 21

For a more flexible and lazy solution, you could match all properties of the objects. Most of the time, this should get you the behavior you want, and you can always be more specific when it doesn't. Here's a grep function that works based on this principle:

Function Select-ObjectPropertyValues {
    param(
    [Parameter(Mandatory=$true,Position=0)]
    [String]
    $Pattern,
    [Parameter(ValueFromPipeline)]
    $input)

    $input | Where-Object {($_.PSObject.Properties | Where-Object {$_.Value -match $Pattern} | Measure-Object).count -gt 0} | Write-Output
}

You can use following lines of code to insert values into an already existing table. Here the table is db_name.table_name having two columns, and I am inserting 'All','done' as a row in the table.

insert into table db_name.table_name
select 'ALL','Done';

Hope this was helpful.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

What you want cannot be done, because plt.legend() places a legend in the current axes, in your case in the last one.

If, on the other hand, you can be content with placing a comprehensive legend in the last subplot, you can do like this

f, (ax1, ax2, ax3) = plt.subplots(3, sharex=True, sharey=True)
l1,=ax1.plot(x,y, color='r', label='Blue stars')
l2,=ax2.plot(x,y, color='g')
l3,=ax3.plot(x,y, color='b')
ax1.set_title('2012/09/15')
plt.legend([l1, l2, l3],["HHZ 1", "HHN", "HHE"])
plt.show()

Note that you pass to legend not the axes, as in your example code, but the lines as returned by the plot invocation.

PS

Of course you can invoke legend after each subplot, but in my understanding you already knew that and were searching for a method for doing it at once.

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(response.GetResponseStream());

Besides these given great answers, What I have learned is that:

NEVER compare objects with == unless you intend to be comparing them by their references.

The properties that can be set for a figure is referenced here.

You could then use:

figure_number = 1;
x      = 0;   % Screen position
y      = 0;   % Screen position
width  = 600; % Width of figure
height = 400; % Height of figure (by default in pixels)

figure(figure_number, 'Position', [x y width height]);

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

.NET 4.0 and above:

using System.Web.Security.AntiXss;
//...
var encoded = AntiXssEncoder.HtmlEncode("input", useNamedEntities: true);

For me this was the issue. This whole block was missing from the section.

Whereas most of the existing answers are great, I would like to include an answer using a traditional for loop, which should also be considered here. The OP requests an answer which is ES5/ES6 compatible, and the traditional for loop applies :)

The problem with using array functions in this scenario, is that they don't mutate objects, but in this case, mutation is a requirement. The performance gain of using a traditional for loop is just a (huge) bonus.

const findThis = 2;
const items = [{id:1, ...}, {id:2, ...}, {id:3, ...}];

for (let i = 0, l = items.length; i < l; ++i) {
  if (items[i].id === findThis) {
    items[i].iAmChanged = true;
    break;
  }
}

Although I am a great fan of array functions, don't let them be the only tool in your toolbox. If the purpose is mutating the array, they are not the best fit.

Working in 2018 (Spark 2.3)

Python

df = spark.read
    .option("header", "true")
    .format("csv")
    .schema(myManualSchema)
    .load("mycsv.csv")

Scala

val myDf = spark.read
  .option("header", "true")
  .format("csv")
  .schema(myManualSchema)
  .load("mycsv.csv")

PD1: myManualSchema is a predefined schema written by me, you could skip that part of code

UPDATE 2021 The same code works for Spark 3.x

df = spark.read
    .option("header", "true")
    .option("inferSchema", "true")
    .format("csv")
    .csv("mycsv.csv")

I unable to comment on the top answer, but Excel actually lets you do this without adding the ugly conditional logic.

Conditional formatting is automatically applied to any input that isn't an error, so you can achieve the same effect as:

=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))

With this:

= MATCH(A1,$B$1:$B$1000,0)))

If the above is applied to your data, A1 will be formatted if it matches any cell in $B$1:$B$1000, as any non-match will return an error.

• json.loads take a string as input and returns a dictionary as output.
• json.dumps take a dictionary as input and returns a string as output.

If you need to convert JSON data into a python object, it can do so with Python3, in one line without additional installations, using SimpleNamespace and object_hook:

from string

import json
from types import SimpleNamespace

string = '{"foo":3, "bar":{"x":1, "y":2}}'

# Parse JSON into an object with attributes corresponding to dict keys.
x = json.loads(string, object_hook=lambda d: SimpleNamespace(**d))

print(x.foo)
print(x.bar.x)
print(x.bar.y)

output:

3
1
2

from file:

JSON object: data.json

{
    "foo": 3,
    "bar": {
        "x": 1,
        "y": 2
    }
}

import json
from types import SimpleNamespace

with open("data.json") as fh:
    string = fh.read()

# Parse JSON into an object with attributes corresponding to dict keys.
x = json.loads(string, object_hook=lambda d: SimpleNamespace(**d))

print(x.foo)
print(x.bar.x)
print(x.bar.y)

output:

3
1
2

from requests

import json
from types import SimpleNamespace
import requests

r = requests.get('https://api.github.com/users/MilovanTomasevic')

# Parse JSON into an object with attributes corresponding to dict keys.
x = json.loads(r.text, object_hook=lambda d: SimpleNamespace(**d))

print(x.name)
print(x.company)
print(x.blog)

output:

.shape() gives the actual shape of your array in terms of no of elements in it, No of rows/No of Columns. The answer you get is in the form of tuples.

For Example: 1D ARRAY:

d=np.array([1,2,3,4])
print(d)
(1,)

Output: (4,) ie the number4 denotes the no of elements in the 1D Array.

2D Array:

e=np.array([[1,2,3],[4,5,6]])   
print(e)
(2,3)

Output: (2,3) ie the number of rows and the number of columns.

The number of elements in the final output will depend on the number of rows in the Array....it goes on increasing gradually.

SELECT DATABASE() worked in PHPMyAdmin.

From the Reflector'd source:

public static List<TSource> ToList<TSource>(this IEnumerable<TSource> source)
{
    if (source == null)
    {
        throw Error.ArgumentNull("source");
    }
    return new List<TSource>(source);
}

So yes, your original list won't be updated (i.e. additions or removals) however the referenced objects will.

With Swift 5.1, Grand Central Dispatch offers many ways to solve your problem. According to your needs, you may choose one of the seven patterns shown in the following Playground snippets.

#1. Using DispatchGroup, DispatchGroup's notify(qos:flags:queue:execute:) and DispatchQueue's async(group:qos:flags:execute:)

The Apple Developer Concurrency Programming Guide states about DispatchGroup:

Dispatch groups are a way to block a thread until one or more tasks finish executing. You can use this behavior in places where you cannot make progress until all of the specified tasks are complete. For example, after dispatching several tasks to compute some data, you might use a group to wait on those tasks and then process the results when they are done.

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)
let group = DispatchGroup()

queue.async(group: group) {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

queue.async(group: group) {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

group.notify(queue: queue) {
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#2. Using DispatchGroup, DispatchGroup's wait(), DispatchGroup's enter() and DispatchGroup's leave()

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)
let group = DispatchGroup()

group.enter()
queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
    group.leave()
}

group.enter()
queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
    group.leave()
}

queue.async {
    group.wait()
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

Note that you can also mix DispatchGroup wait() with DispatchQueue async(group:qos:flags:execute:) or mix DispatchGroup enter() and DispatchGroup leave() with DispatchGroup notify(qos:flags:queue:execute:).

#3. Using Dispatch?Work?Item?Flags barrier and DispatchQueue's async(group:qos:flags:execute:)

Grand Central Dispatch Tutorial for Swift 4: Part 1/2 article from Raywenderlich.com gives a definition for barriers:

Dispatch barriers are a group of functions acting as a serial-style bottleneck when working with concurrent queues. When you submit a DispatchWorkItem to a dispatch queue you can set flags to indicate that it should be the only item executed on the specified queue for that particular time. This means that all items submitted to the queue prior to the dispatch barrier must complete before the DispatchWorkItem will execute.

Usage:

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)

queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

queue.async(flags: .barrier) {
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#4. Using DispatchWorkItem, Dispatch?Work?Item?Flags's barrier and DispatchQueue's async(execute:)

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)

queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

let dispatchWorkItem = DispatchWorkItem(qos: .default, flags: .barrier) {
    print("#3 finished")
}

queue.async(execute: dispatchWorkItem)

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#5. Using DispatchSemaphore, DispatchSemaphore's wait() and DispatchSemaphore's signal()

Soroush Khanlou wrote the following lines in The GCD Handbook blog post:

Using a semaphore, we can block a thread for an arbitrary amount of time, until a signal from another thread is sent. Semaphores, like the rest of GCD, are thread-safe, and they can be triggered from anywhere. Semaphores can be used when there’s an asynchronous API that you need to make synchronous, but you can’t modify it.

Apple Developer API Reference also gives the following discussion for DispatchSemaphore init(value:?) initializer:

Passing zero for the value is useful for when two threads need to reconcile the completion of a particular event. Passing a value greater than zero is useful for managing a finite pool of resources, where the pool size is equal to the value.

Usage:

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let queue = DispatchQueue(label: "com.company.app.queue", attributes: .concurrent)
let semaphore = DispatchSemaphore(value: 0)

queue.async {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
    semaphore.signal()
}

queue.async {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
    semaphore.signal()
}

queue.async {
    semaphore.wait()
    semaphore.wait()    
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 */

#6. Using OperationQueue and Operation's addDependency(_:)

The Apple Developer API Reference states about Operation?Queue:

Operation queues use the libdispatch library (also known as Grand Central Dispatch) to initiate the execution of their operations.

Usage:

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let operationQueue = OperationQueue()

let blockOne = BlockOperation {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

let blockTwo = BlockOperation {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

let blockThree = BlockOperation {
    print("#3 finished")
}

blockThree.addDependency(blockOne)
blockThree.addDependency(blockTwo)

operationQueue.addOperations([blockThree, blockTwo, blockOne], waitUntilFinished: false)

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 or
 #2 started
 #1 started
 #2 finished
 #1 finished
 #3 finished
 */

#7. Using OperationQueue and OperationQueue's addBarrierBlock(_:) (requires iOS 13)

import Foundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let operationQueue = OperationQueue()

let blockOne = BlockOperation {
    print("#1 started")
    Thread.sleep(forTimeInterval: 5)
    print("#1 finished")
}

let blockTwo = BlockOperation {
    print("#2 started")
    Thread.sleep(forTimeInterval: 2)
    print("#2 finished")
}

operationQueue.addOperations([blockTwo, blockOne], waitUntilFinished: false)
operationQueue.addBarrierBlock {
    print("#3 finished")
}

/*
 prints:
 #1 started
 #2 started
 #2 finished
 #1 finished
 #3 finished
 or
 #2 started
 #1 started
 #2 finished
 #1 finished
 #3 finished
 */

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

you must implement IComparer interface.

In this sample I've my custom object JSONReturn, I implement my class like this :

Friend Class JSONReturnComparer
    Implements IComparer(of JSONReturn)

    Public Function Compare(x As JSONReturn, y As JSONReturn) As Integer Implements    IComparer(Of JSONReturn).Compare
        Return String.Compare(x.Name, y.Name)
    End Function

End Class

I call my sort List method like this : alResult.Sort(new JSONReturnComparer())

Maybe it could help you

A simple answer if you don't want to install anything new

To change all the fonts in your plot plot + theme(text=element_text(family="mono")) Where mono is your chosen font.

List of default font options:

• mono
• sans
• serif
• Courier
• Helvetica
• Times
• AvantGarde
• Bookman
• Helvetica-Narrow
• NewCenturySchoolbook
• Palatino
• URWGothic
• URWBookman
• NimbusMon
• URWHelvetica
• NimbusSan
• NimbusSanCond
• CenturySch
• URWPalladio
• URWTimes
• NimbusRom

R doesn't have great font coverage and, as Mike Wise points out, R uses different names for common fonts.

This page goes through the default fonts in detail.

You can use any of these in your scenario since they write to the default streams (output and error). If you were piping output to another commandlet you would want to use Write-Output, which will eventually terminate in Write-Host.

This article describes the different output options: PowerShell O is for Output

Addendum:

The important concept is that you are evaluating an expression in your Razor code. The best way to do this (if, for example, you are in a foreach loop) is using a generic method.

The syntax for calling a generic method in Razor is:

@(expression)

In this case, the expression is:

User.Identity.IsAuthenticated ? "auth" : "anon"

Therefore, the solution is:

@(User.Identity.IsAuthenticated ? "auth" : "anon")

This code can be used anywhere in Razor, not just for an html attribute.

See @Kyralessa 's comment for C# Razor Syntax Quick Reference (Phil Haack's blog).

It is possible to do this, but most likely your host implemented mod_security for a reason. Be sure they approve of you disabling it for your own site.

That said, this should do it;

<IfModule mod_security.c>
  SecFilterEngine Off
  SecFilterScanPOST Off
</IfModule>

<xsl:call-template> is a close equivalent to calling a function in a traditional programming language.

You can define functions in XSLT, like this simple one that outputs a string.

<xsl:template name="dosomething">
  <xsl:text>A function that does something</xsl:text>
</xsl:template>

This function can be called via <xsl:call-template name="dosomething">.

<xsl:apply-templates> is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:

<!-- sample XML snippet -->
<xml>
  <foo /><bar /><baz />
</xml>

<!-- sample XSLT snippet -->
<xsl:template match="xml">
  <xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>

<xsl:template match="foo"> <!-- will be called once -->
  <xsl:text>foo element encountered</xsl:text>
</xsl:template>

<xsl:template match="*"> <!-- will be called twice -->
  <xsl:text>other element countered</xsl:text>
</xsl:template>

This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.

If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.

You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).

A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates> the current node moves on with every iteration, whereas <xsl:call-template> does not change the current node. I.e. the . within a called template refers to the same node as the . in the calling template. This is not the case with apply-templates.

This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode and priority, the fact that templates can have both a name and a match. It also has an impact whether the template has been imported (<xsl:import>) or not. These are advanced uses and you can deal with them when you get there.

You can add a class to the parent of the red div, e.g. green-style

$('.red').parent().addClass('green-style');

then add style to the css

.green-style .red {
     background:green; 
}

so everytime you add red element under green-style, the background will be green

Or... You could place the image in an anchor tag. Cause I had the same problem and it fixed it without issue. A lot of people use local paths before they publish their site and photos. Just make sure you go back and fix that in the final editing phase.

1) If a DataFrame has got Nan and Non Null values and you want to find whether the DataFrame
is empty or not then try this code.
2) when this situation can happen? 
This situation happens when a single function is used to plot more than one DataFrame 
which are passed as parameter.In such a situation the function try to plot the data even 
when a DataFrame is empty and thus plot an empty figure!.
It will make sense if simply display 'DataFrame has no data' message.
3) why? 
if a DataFrame is empty(i.e. contain no data at all.Mind you DataFrame with Nan values 
is considered non empty) then it is desirable not to plot but put out a message :
Suppose we have two DataFrames df1 and df2.
The function myfunc takes any DataFrame(df1 and df2 in this case) and print a message 
if a DataFrame is empty(instead of plotting):

df1                     df2
col1 col2           col1 col2 
Nan   2              Nan  Nan 
2     Nan            Nan  Nan  

and the function:

def myfunc(df):
  if (df.count().sum())>0: ##count the total number of non Nan values.Equal to 0 if DataFrame is empty
     print('not empty')
     df.plot(kind='barh')
  else:
     display a message instead of plotting if it is empty
     print('empty')

You don't need the separate fill item. In fact, it's invalid. You just have to add a solid block to the shape. The subsequent stroke draws on top of the solid:

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

    <corners android:radius="5dp" />
    <solid android:color="@android:color/white" />
    <stroke
        android:width="1dip"
        android:color="@color/bggrey" />
</shape>

You also don't need the layer-list if you only have one shape.

As Jose answered, screen -d -r should do the trick. This is a combination of two commands, as taken from the man page.

screen -d detaches the already-running screen session, and screen -r reattaches the existing session. By running screen -d -r, you force screen to detach it and then resume the session.

If you use the capital -D -RR, I quote the man page because it's too good to pass up.

Attach here and now. Whatever that means, just do it.

Note: It is always a good idea to check the status of your sessions by means of "screen -list".

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

If you use mysql 5.6 server and have problems with C:\Program Files\MySQL\MySQL Server 5.6\my.ini:

You should go to C:\ProgramData\MySQL\MySQL Server 5.6\my.ini.

You should add skip-grant-tables and then you do not need a password.

# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.

If you don't have PHP 5.2 you can use something like this:

function js_str($s)
{
    return '"' . addcslashes($s, "\0..\37\"\\") . '"';
}

function js_array($array)
{
    $temp = array_map('js_str', $array);
    return '[' . implode(',', $temp) . ']';
}

echo 'var cities = ', js_array($php_cities_array), ';';

Linux

Run ps and determine the PID of your node process.

Then, run sudo kill PID

Windows

Use tasklist to display the list of running processes:

tasklist /O

Then, kill the node process like so (using the PID obtained from the tasklist command):

taskkill /pid PID

For large datasets, it is memory efficient to read only selected rows via the skiprows parameter.

Example

pred = lambda x: x not in [1, 3]
pd.read_csv("data.csv", skiprows=pred, index_col=0, names=...)

This will now return a DataFrame from a file that skips all rows except 1 and 3.

Details

From the docs:

skiprows : list-like or integer or callable, default None

...

If callable, the callable function will be evaluated against the row indices, returning True if the row should be skipped and False otherwise. An example of a valid callable argument would be lambda x: x in [0, 2]

This feature works in version pandas 0.20.0+. See also the corresponding issue and a related post.

If you're using Node.js:

In that req.user is ObjectId format.

var mongoose = require("mongoose");
var ObjectId = mongoose.Schema.Types.ObjectId;

function getUsers(req, res)
    User.findOne({"_id":req.user}, { password: 0 }) 
         .then(data => {

Thanks for the replies.
What I did was,
1. I install meinberg ntp software application on windows 7 pc. (softros ntp server is also possible.)
2. change raspberry pi ntp.conf file (for auto update date and time)

server xxx.xxx.xxx.xxx iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst

3. If you want to make sure that date and time update at startup run this python script in rpi,

import os

try:
    client = ntplib.NTPClient()
    response = client.request('xxx.xxx.xxx.xxx', version=4)
    print "===================================="
    print "Offset : "+str(response.offset)
    print "Version : "+str(response.version)
    print "Date Time : "+str(ctime(response.tx_time))
    print "Leap : "+str(ntplib.leap_to_text(response.leap))
    print "Root Delay : "+str(response.root_delay)
    print "Ref Id : "+str(ntplib.ref_id_to_text(response.ref_id))
    os.system("sudo date -s '"+str(ctime(response.tx_time))+"'")
    print "===================================="
except:
    os.system("sudo date")
    print "NTP Server Down Date Time NOT Set At The Startup"
    pass

I found more info in raspberry pi forum.

The JavaScript appendchild method can be use to append an item to another element. The jQuery Append element does the same work but certainly in less number of lines:

Let us take an example to Append an item in a list:

a) With JavaScript

var n= document.createElement("LI");                 // Create a <li> node
var tn = document.createTextNode("JavaScript");      // Create a text node
n.appendChild(tn);                                   // Append the text to <li>
document.getElementById("myList").appendChild(n);  

b) With jQuery

$("#myList").append("<li>jQuery</li>")

One place where it's useful is for UI activities, like setting a spinner before a lengthy operation:

- (void) handleDoSomethingButton{

    [mySpinner startAnimating];

    (do something lengthy)
    [mySpinner stopAnimating];
}

will not work, because you are blocking the main thread during your lengthy thing and not letting UIKit actually start the spinner.

- (void) handleDoSomethingButton{
     [mySpinner startAnimating];

     dispatch_async (dispatch_get_main_queue(), ^{
          (do something lengthy)
          [mySpinner stopAnimating];
    });
}

will return control to the run loop, which will schedule UI updating, starting the spinner, then will get the next thing off the dispatch queue, which is your actual processing. When your processing is done, the animation stop is called, and you return to the run loop, where the UI then gets updated with the stop.

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

I must add :

I had the same problem, it was coming from the fact that my teammate had a different version of cordova, and commited plugins on the repo with his version.

For all cordova plugins, I had to :

cordova plugin rm <plugin-name> 
cordova plugin add <plugin-name>

And ask my teammate to update his cordova to match my version

Example of single, double, heredoc, and nowdoc quotes

<?php

    $fname = "David";

    // Single quotes
    echo 'My name is $fname.'; // My name is $fname.

    // Double quotes
    echo "My name is $fname."; // My name is David.

    // Curly braces to isolate the name of the variable
    echo "My name is {$fname}."; // My name is David.

    // Example of heredoc
    echo $foo = <<<abc
    My name is {$fname}
    abc;

        // Example of nowdoc
        echo <<< 'abc'
        My name is "$name".
        Now, I am printing some
    abc;

?>

In Swift 4.2 and Xcode 10.1

We have three types of Queues :

1. Main Queue: Main queue is a serial queue which is created by the system and associated with the application main thread.

2. Global Queue : Global queue is a concurrent queue which we can request with respect to the priority of the tasks.

3. Custom queues : can be created by the user. Custom concurrent queues always mapped into one of the global queues by specifying a Quality of Service property (QoS).

DispatchQueue.main//Main thread
DispatchQueue.global(qos: .userInitiated)// High Priority
DispatchQueue.global(qos: .userInteractive)//High Priority (Little Higher than userInitiated)
DispatchQueue.global(qos: .background)//Lowest Priority
DispatchQueue.global(qos: .default)//Normal Priority (after High but before Low)
DispatchQueue.global(qos: .utility)//Low Priority
DispatchQueue.global(qos: .unspecified)//Absence of Quality

These all Queues can be executed in two ways

1. Synchronous execution

2. Asynchronous execution

DispatchQueue.global(qos: .background).async {
    // do your job here
    DispatchQueue.main.async {
        // update ui here
    }
}

//Perform some task and update UI immediately.
DispatchQueue.global(qos: .userInitiated).async {  
    // Perform task
    DispatchQueue.main.async {  
        // Update UI
        self.tableView.reloadData()  
    }
}

//To call or execute function after some time
DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
    //Here call your function
}

//If you want to do changes in UI use this
DispatchQueue.main.async(execute: {
    //Update UI
    self.tableView.reloadData()
})

From AppCoda : https://www.appcoda.com/grand-central-dispatch/

//This will print synchronously means, it will print 1-9 & 100-109
func simpleQueues() {
    let queue = DispatchQueue(label: "com.appcoda.myqueue")

    queue.sync {
        for i in 0..<10 {
            print("", i)
        }
    }

    for i in 100..<110 {
        print("??", i)
    }
}

//This will print asynchronously 
func simpleQueues() {
    let queue = DispatchQueue(label: "com.appcoda.myqueue")

    queue.async {
        for i in 0..<10 {
            print("", i)
        }
    }

    for i in 100..<110 {
        print("??", i)
    }
}

As a workaround you can use the fact percent vertical padding and margin are computed from the container width. It's quite a ugly solution and I don't know if you'll be able to use it but well, it works: http://jsfiddle.net/bFWT9/

Assuming you are using debian linux (I'm using Linux mint 12, problem was on Ubuntu 12.04.1 LTS server I ssh'ed into.)

I suggest taking @dkamins advice and making sure you have mcrypt installed and active on your php5 install. Use "sudo apt-get install php5-mcrypt" to install. My notes below.

Using PHP version PHP Version 5.3.10-1ubuntu3.4, if you open phpinfo() as suggested by @John Conde, which you do by creating test file on web server (e.g. create status page testphp.php with just the contents "" anywhere accessible on the server via browser)

I found no presence of enabled or disabled status on the status page when opened in browser. When I then opened the php.ini file, mentioned by @Anthony Forloney, thinking to uncomment ;extension=php_mcrypt.dll to extension=php_mcrypt.dll

I toggled that back and forth and restarted Apache (I'm running Apache2 and you can restart in my setup with sudo /etc/init.d/apache2 restart or when you are in that directory just sudo restart I believe) with change and without change but all no go. I took @dkamins advice and went to install the package with "sudo apt-get install php5-mcrypt" and then restarted apache as above. Then my error was gone and my application worked fine.

javascript does not not have a compiler like for example Java/C(You can compare it more to languages like PHP for example). If you want to write compiled code you should read the section about addons and learn C. Although this is rather complex and I don't think you need to do this but instead just write javascript.

A year after asking the question comes a new article on the subject:

http://erniemiller.org/2014/10/23/in-defense-of-alias/

It seems that "so many men, so many minds." From the former article author encourages to use alias_method, while the latter suggests using alias.

However there's a common overview of these methods in both blogposts and answers above:

• use alias when you want to limit aliasing to the scope where it's defined
• use alias_method to allow inherited classes to access it

NOTE: Doesn't work on newer versions of jQuery.

Since you are using jQuery please use it's seralize function to serialize data and then pass it into the data parameter of ajax call:

info[0] = 'hi';
info[1] = 'hello';

var data_to_send = $.serialize(info);

$.ajax({
    type: "POST",
    url: "index.php",
    data: data_to_send,
    success: function(msg){
        $('.answer').html(msg);
    }
});

bash has a builtin

PyLibTiff worked better for me than PIL, which as of December 2020 still doesn't support color images with more than 8 bits per color.

from libtiff import TIFF

tif = TIFF.open('filename.tif') # open tiff file in read mode
# read an image in the currect TIFF directory as a numpy array
image = tif.read_image()

# read all images in a TIFF file:
for image in tif.iter_images(): 
    pass

tif = TIFF.open('filename.tif', mode='w')
tif.write_image(image)

You can install PyLibTiff with

pip3 install numpy libtiff

The readme of PyLibTiff also mentions the tifffile library but I haven't tried it.

In Kotlin, if you refer the Button View with id then, enable/disable button as like

layout.xml

<Button
   android:id="@+id/btn_start"
   android:layout_width="100dp"
   android:layout_height="50dp"
   android:text="@string/start"
   android:layout_alignParentBottom="true"/>

activity.kt

  btn_start.isEnabled = true   //to enable button
  btn_start.isEnabled = false  //to disable button

On fedora/rhel/centos you need to

sudo yum install -y python3-devel

before

mkvirtualenv -p /usr/bin/python3.3 test-3.3
pip install numpy

otherwise you'll get

SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

Often when people are looking for "timezones", what will suffice is just "UTC offset". e.g., their server is in UTC+5 and they want to know that their client is running in UTC-8.

In plain old javascript (new Date()).getTimezoneOffset()/60 will return the current number of hours offset from UTC.

It's worth noting a possible "gotcha" in the sign of the getTimezoneOffset() return value (from MDN docs):

The time-zone offset is the difference, in minutes, between UTC and local time. Note that this means that the offset is positive if the local timezone is behind UTC and negative if it is ahead. For example, for time zone UTC+10:00 (Australian Eastern Standard Time, Vladivostok Time, Chamorro Standard Time), -600 will be returned.

However, I recommend you use the day.js for time/date related Javascript code. In which case you can get an ISO 8601 formatted UTC offset by running:

> dayjs().format("Z")
"-08:00"

It probably bears mentioning that the client can easily falsify this information.

(Note: this answer originally recommended https://momentjs.com/, but dayjs is a more modern, smaller alternative.)

This worked for me:

If you wrote your Serialized class object into a file, then made some changes to file and compiled it, and then you try to read an object, then this will happen.

So, write the necessary objects to file again if a class is modified and recompiled.

PS: This is NOT a solution; was meant to be a workaround.

We can add additional columns to DataFrame directly with below steps:

from pyspark.sql.functions import when
df = spark.createDataFrame([["amit", 30], ["rohit", 45], ["sameer", 50]], ["name", "age"])
df = df.withColumn("profile", when(df.age >= 40, "Senior").otherwise("Executive"))
df.show()

This answer covers a lot of ground, so it’s divided into three parts:

• How to use a CORS proxy to get around “No Access-Control-Allow-Origin header” problems
• How to avoid the CORS preflight
• How to fix “Access-Control-Allow-Origin header must not be the wildcard” problems

How to use a CORS proxy to avoid “No Access-Control-Allow-Origin header” problems

If you don’t control the server your frontend code is sending a request to, and the problem with the response from that server is just the lack of the necessary Access-Control-Allow-Origin header, you can still get things to work—by making the request through a CORS proxy.

You can easily run your own proxy using code from https://github.com/Rob--W/cors-anywhere/.
You can also easily deploy your own proxy to Heroku in just 2-3 minutes, with 5 commands:

git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master

After running those commands, you’ll end up with your own CORS Anywhere server running at, e.g., https://cryptic-headland-94862.herokuapp.com/.

Now, prefix your request URL with the URL for your proxy:

https://cryptic-headland-94862.herokuapp.com/https://example.com

Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:

1. Forwards the request to https://example.com.
2. Receives the response from https://example.com.
3. Adds the Access-Control-Allow-Origin header to the response.
4. Passes that response, with that added header, back to the requesting frontend code.

The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin response header is what the browser sees.

This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS request, because in that case, the proxy also sends back the Access-Control-Allow-Headers and Access-Control-Allow-Methods headers needed to make the preflight successful.

How to avoid the CORS preflight

The code in the question triggers a CORS preflight—since it sends an Authorization header.

https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Preflighted_requests

Even without that, the Content-Type: application/json header would also trigger a preflight.

What “preflight” means: before the browser tries the POST in the code in the question, it’ll first send an OPTIONS request to the server — to determine if the server is opting-in to receiving a cross-origin POST that has Authorization and Content-Type: application/json headers.

It works pretty well with a small curl script - I get my data.

To properly test with curl, you must emulate the preflight OPTIONS request the browser sends:

curl -i -X OPTIONS -H "Origin: http://127.0.0.1:3000" \
    -H 'Access-Control-Request-Method: POST' \
    -H 'Access-Control-Request-Headers: Content-Type, Authorization' \
    "https://the.sign_in.url"

…with https://the.sign_in.url replaced by whatever your actual sign_in URL is.

The response the browser needs to see from that OPTIONS request must have headers like this:

Access-Control-Allow-Origin:  http://127.0.0.1:3000
Access-Control-Allow-Methods: POST
Access-Control-Allow-Headers: Content-Type, Authorization

If the OPTIONS response doesn’t include those headers, then the browser will stop right there and never even attempt to send the POST request. Also, the HTTP status code for the response must be a 2xx—typically 200 or 204. If it’s any other status code, the browser will stop right there.

The server in the question is responding to the OPTIONS request with a 501 status code, which apparently means it’s trying to indicate it doesn’t implement support for OPTIONS requests. Other servers typically respond with a 405 “Method not allowed” status code in this case.

So you’re never going to be able to make POST requests directly to that server from your frontend JavaScript code if the server responds to that OPTIONS request with a 405 or 501 or anything other than a 200 or 204 or if doesn’t respond with those necessary response headers.

The way to avoid triggering a preflight for the case in the question would be:

• if the server didn’t require an Authorization request header but instead, e.g., relied on authentication data embedded in the body of the POST request or as a query param
• if the server didn’t require the POST body to have a Content-Type: application/json media type but instead accepted the POST body as application/x-www-form-urlencoded with a parameter named json (or whatever) whose value is the JSON data

How to fix “Access-Control-Allow-Origin header must not be the wildcard” problems

I am getting another error message:

The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://127.0.0.1:3000' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

For a request that includes credentials, browsers won’t let your frontend JavaScript code access the response if the value of the Access-Control-Allow-Origin response header is *. Instead the value in that case must exactly match your frontend code’s origin, http://127.0.0.1:3000.

See Credentialed requests and wildcards in the MDN HTTP access control (CORS) article.

If you control the server you’re sending the request to, then a common way to deal with this case is to configure the server to take the value of the Origin request header, and echo/reflect that back into the value of the Access-Control-Allow-Origin response header; e.g., with nginx:

add_header Access-Control-Allow-Origin $http_origin

But that’s just an example; other (web) server systems provide similar ways to echo origin values.

I am using Chrome. I also tried using that Chrome CORS Plugin

That Chrome CORS plugin apparently just simplemindedly injects an Access-Control-Allow-Origin: * header into the response the browser sees. If the plugin were smarter, what it would be doing is setting the value of that fake Access-Control-Allow-Origin response header to the actual origin of your frontend JavaScript code, http://127.0.0.1:3000.

So avoid using that plugin, even for testing. It’s just a distraction. To test what responses you get from the server with no browser filtering them, you’re better off using curl -H as above.

As far as the frontend JavaScript code for the fetch(…) request in the question:

headers.append('Access-Control-Allow-Origin', 'http://localhost:3000');
headers.append('Access-Control-Allow-Credentials', 'true');

Remove those lines. The Access-Control-Allow-* headers are response headers. You never want to send them in a request. The only effect that’ll have is to trigger a browser to do a preflight.

While we are talking about STL, maps and dictionary, I'd recommend taking a look at the C5 library. It offers several types of dictionaries and maps that I've frequently found useful (along with many other interesting and useful data structures).

If you are a C++ programmer moving to C# as I did, you'll find this library a great resource (and a data structure for this dictionary).

-Paul

I had to do this to get it to work:

$pair = "$($user):$($pass)"
$encodedCredentials = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($Pair))
$headers = @{ Authorization = "Basic $encodedCredentials" }
Invoke-WebRequest -Uri $url -Method Get -Headers $headers -OutFile Config.html

There can be two aspects developer may face.

• Either he wants to remove pods completely from project
• developer wants to uninstall particular framework from project from pods.

In first case you have to use 'pod deintegrate' and follow several steps which are mentioned in the answers above.

For second case that is if you want to uninstall any particular framework which is installed there very simple way available in your pod file just comment the framework which you want to uninstall and run pod install command.

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'
target 'ProjectName' do
  # Uncomment this line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

    pod 'iCarousel', '~> 1.8'
#    pod 'Facebook-iOS-SDK', '~> 4.1'
#    pod 'ParseFacebookUtilsV4', '~> 1.11'
#    pod 'Parse', '~> 1.14'


end

Here I want to uninstall facebook and parse frameworks (which were installed using pods) and not iCarousel that is why I have updated my pod file like above.

Now if I run pod install it will keep iCarousel as it is in my project and will remove facebook and parse.

It's very simple.

If you want to have something like a glyphicon icon and then "Wish List",

<span class="glyphicon-heart"></span> @Html.ActionLink("Wish List (0)", "Index", "Home")

system ('/usr/bin/pdfcrop filename.pdf'); 

Extending @DomTomCat and others' approach, these functional (ie, return modified data via deepcopy without affecting the input) setter and mapper works for nested dict and list.

setter:

def set_at_path(data0, keys, value):
    data = deepcopy(data0)
    if len(keys)>1:
        if isinstance(data,dict):
            return {k:(set_by_path(v,keys[1:],value) if k==keys[0] else v) for k,v in data.items()}
        if isinstance(data,list):
            return [set_by_path(x[1],keys[1:],value) if x[0]==keys[0] else x[1] for x in enumerate(data)]
    else:
        data[keys[-1]]=value
        return data

mapper:

def map_at_path(data0, keys, f):
    data = deepcopy(data0)
    if len(keys)>1:
        if isinstance(data,dict):
            return {k:(map_at_path(v,keys[1:],f) if k==keys[0] else v) for k,v in data.items()}
        if isinstance(data,list):
            return [map_at_path(x[1],keys[1:],f) if x[0]==keys[0] else x[1] for x in enumerate(data)]
    else:
        data[keys[-1]]=f(data[keys[-1]])
        return data

You can throw an unchecked exception from the method which you wish to roll back. This will be detected by spring and your transaction will be marked as rollback only.

I'm assuming you're using Spring here. And I assume the annotations you refer to in your tests are the spring test based annotations.

The recommended way to indicate to the Spring Framework's transaction infrastructure that a transaction's work is to be rolled back is to throw an Exception from code that is currently executing in the context of a transaction.

and note that:

please note that the Spring Framework's transaction infrastructure code will, by default, only mark a transaction for rollback in the case of runtime, unchecked exceptions; that is, when the thrown exception is an instance or subclass of RuntimeException.

All the other solutions posted here cause the toggle to get out of sync if it is double clicked. The following solution uses the events provided by the Bootstrap framework, and the toggle always matches the state of the collapsible element:

HTML:

<div class="row-fluid summary">
    <div class="span11">
        <h2>MyHeading</h2>  
    </div>
    <div class="span1">
        <button id="intro-switch" class="btn btn-success" data-toggle="collapse" data-target="#intro">+</button>
    </div>
</div>
<div class="row-fluid summary">
    <div id="intro" class="collapse"> 
        Here comes the text...
    </div>
</div>

JS:

$('#intro').on('show', function() {
  $('#intro-switch').html('-')
})
$('#intro').on('hide', function() {
  $('#intro-switch').html('+')
})

That should work for most cases.

However, I also ran into an additional problem when trying to nest one collapsible element and its toggle switch inside another collapsible element. With the above code, when I click the nested toggle to hide the nested collapsible element, the toggle for the parent element also changes. It may be a bug in Bootstrap. I found a solution that seems to work: I added a "collapsed" class to the toggle switches (Bootstrap adds this when the collapsible element is hidden but they don't start out with it), then added that to the jQuery selector for the hide function:

HTML:

<div class="row-fluid summary">
    <div class="span11">
        <h2>MyHeading</h2>  
    </div>
    <div class="span1">
        <button id="intro-switch" class="btn btn-success collapsed" data-toggle="collapse" data-target="#intro">+</button>
    </div>
</div>
<div class="row-fluid summary">
    <div id="intro" class="collapse"> 
        Here comes the text...<br>
        <a id="details-switch" class="collapsed" data-toggle="collapse" href="#details">Show details</a>
        <div id="details" class="collapse">
            More details...
        </div>
    </div>
</div>

JS:

$('#intro').on('show', function() {
    $('#intro-switch').html('-')
})
$('#intro').on('hide', function() {
    $('#intro-switch.collapsed').html('+')
})

$('#details').on('show', function() {
    $('#details-switch').html('Hide details')
})
$('#details').on('hide', function() {
    $('#details-switch.collapsed').html('Show details')
})

It stands for Representational State Transfer and it can mean a lot of things, but usually when you are talking about APIs and applications, you are talking about REST as a way to do web services or get programs to talk over the web.

REST is basically a way of communicating between systems and does much of what SOAP RPC was designed to do, but while SOAP generally makes a connection, authenticates and then does stuff over that connection, REST works pretty much the same way that that the web works. You have a URL and when you request that URL you get something back. This is where things start getting confusing because people describe the web as a the largest REST application and while this is technically correct it doesn't really help explain what it is.

In a nutshell, REST allows you to get two applications talking over the Internet using tools that are similar to what a web browser uses. This is much simpler than SOAP and a lot of what REST does is says, "Hey, things don't have to be so complex."

First off: a List is a Collection. It is a specialized Collection, however.

A Collection is just that: a collection of items. You can add stuff, remove stuff, iterate over stuff and query how much stuff is in there.

A List adds the information about a defined sequence of stuff to it: You can get the element at position n, you can add an element at position n, you can remove the element at position n.

In a Collection you can't do that: "the 5th element in this collection" isn't defined, because there is no defined order.

There are other specialized Collections as well, for example a Set which adds the feature that it will never contain the same element twice.

A possibility is that the git server you are pushing to is down/crashed, and the solution lies in restarting the git server.

Just use dynamic as the argument:

var list = new List<dynamic>();

I had the same problem and I Changed this

<configuration>
    <source>1.7</source>
    <target>1.7</target>
 </configuration>

here 1.7 is my JDK version.it was solved.

<div style="float: left;">
<?php 
  echo("<a href=\"pagea.php?id=$id\">Page A</a>") 
?>
</div>
<div id="contentInfo_new" style="float: left;">
  <script type="text/javascript" src="getData.php?id=<?php echo($id); ?>"></script>
</div>

So, is that a behavior to expect, a bug

Truth be told I am not sure. It looks like parser is interpreting count not as a column name but a function and expects following parentheses. Looks like a bug or at least a serious limitation of the parser.

is there a canonical way to go around?

Some options have been already mentioned by Herman and mattinbits so here more SQLish approach from me:

import org.apache.spark.sql.functions.count

df.groupBy("x").agg(count("*").alias("cnt")).where($"cnt"  > 2)

For what it's worth.

```{r eval=FALSE}

The document will display the code by default but will prevent the code block from being executed, and thus will also not display any results.

The 'best' way to do this would be to set a property on a view object once the update is successful. You can then access this property in the view and inform the user accordingly.

Having said that it would be possible to trigger an alert from the controller code by doing something like this -

public ActionResult ActionName(PostBackData postbackdata)
{
    //your DB code
    return new JavascriptResult { Script = "alert('Successfully registered');" };
}

A simpler way of doing it is:

var dictionary = list.GroupBy(it => it.Key).ToDictionary(dict => dict.Key, dict => dict.Select(item => item.value).ToList());
