As a one liner:

ImageIO.write(Scalr.resize(ImageIO.read(...), 150));

This looks like what you actually want. It applies the same approach of this answer to your specific case:

import matplotlib.pyplot as plt

fig, ax = plt.subplots(nrows=3, ncols=3, sharex=True, sharey=True, figsize=(6, 6))

fig.text(0.5, 0.04, 'common X', ha='center')
fig.text(0.04, 0.5, 'common Y', va='center', rotation='vertical')

The reason it didn't work is that despite setting the border-width and the border-color you didn't specify the border-style:

<table style="border-width:1px;border-color:black;border-style:solid;">

JS Fiddle demo.

It's usually better to define the styles in the stylesheet (so that all elements are styled without having to find, and change, every element's style attribute):

table {
    border-color: #000;
    border-width: 1px;
    border-style: solid;
    /* or, of course,
    border: 1px solid #000;
    */
}

Replace your query with the following:

$query = mysql_query("INSERT INTO users VALUES('$username','$pass','$email')", `$Connect`);

The DUAL table is a special one-row table present by default in all Oracle database installations. It is suitable for use in selecting a pseudocolumn such as SYSDATE or USER

The table has a single VARCHAR2(1) column called DUMMY that has a value of "X"

You can read all about it in http://en.wikipedia.org/wiki/DUAL_table

You could spare yourself the transformations, you could use CSS3 Transitions to flip <div>'s and <ol>'s and any HTML tag you want. Here are some demos with source code explain to see and learn: http://www.webdesignerwall.com/trends/47-amazing-css3-animation-demos/

How about this: I used it with a mixin

non-compliant object

@Entity
@Getter
@NoArgsConstructor
public class Telemetry {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long pk;
    private String id;
    private String organizationId;
    private String baseType;
    private String name;
    private Double lat;
    private Double lon;
    private Instant updateTimestamp;
}

Mixin:

@JsonAutoDetect(fieldVisibility = ANY, getterVisibility = NONE, setterVisibility = NONE)
public static class TelemetryMixin {}

Usage:

    ObjectMapper om = objectMapper.addMixIn(Telemetry.class, TelemetryMixin.class);
    Telemetry[] telemetries = om.readValue(someJson, Telemetry[].class);

There is nothing that says you couldn't foreach any number of classes and apply the same mixin.

If you're not familiar with mixins, they are conceptually simply: The structure of the mixin is super imposed on the target class (according to jackson, not as far as the JVM is concerned).

You need to merge the remote branch into your current branch by running git pull.

If your local branch is already up-to-date, you may also need to run git pull --rebase.

A quick google search also turned up this same question asked by another SO user: Cannot push to GitHub - keeps saying need merge. More details there.

According to the standard, you should be safe with that assumption. The C++ bool type has two values - true and false with corresponding values 1 and 0.

The thing to watch about for is mixing bool expressions and variables with BOOL expression and variables. The latter is defined as FALSE = 0 and TRUE != FALSE, which quite often in practice means that any value different from 0 is considered TRUE.

A lot of modern compilers will actually issue a warning for any code that implicitly tries to cast from BOOL to bool if the BOOL value is different than 0 or 1.

Way 1: only works for dataURL, not for other types of url.

 function dataURLtoFile(dataurl, filename) {_x000D_
 _x000D_
        var arr = dataurl.split(','),_x000D_
            mime = arr[0].match(/:(.*?);/)[1],_x000D_
            bstr = atob(arr[1]), _x000D_
            n = bstr.length, _x000D_
            u8arr = new Uint8Array(n);_x000D_
            _x000D_
        while(n--){_x000D_
            u8arr[n] = bstr.charCodeAt(n);_x000D_
        }_x000D_
        _x000D_
        return new File([u8arr], filename, {type:mime});_x000D_
    }_x000D_
    _x000D_
    //Usage example:_x000D_
    var file = dataURLtoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=','hello.txt');_x000D_
    console.log(file);

Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)

 //return a promise that resolves with a File instance_x000D_
    function urltoFile(url, filename, mimeType){_x000D_
        return (fetch(url)_x000D_
            .then(function(res){return res.arrayBuffer();})_x000D_
            .then(function(buf){return new File([buf], filename,{type:mimeType});})_x000D_
        );_x000D_
    }_x000D_
    _x000D_
    //Usage example:_x000D_
    urltoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=', 'hello.txt','text/plain')_x000D_
    .then(function(file){ console.log(file);});

The string is basically bounded from the place where it is pointed to (char *ptrChar;), to the null character (\0).

The char *ptrChar; actually points to the beginning of the string (char array), and thus that is the pointer to that string, so when you do like ptrChar[x] for example, you actually access the memory location x times after the beginning of the char (aka from where ptrChar is pointing to).

Time of Sleep Function is in milliseconds (ms)

if you want 3 minutes, thats the way to do it:

WScript.Sleep(1000 * 60 * 3)

C# knows two terms, delegate and event. Let's start with the first one.

Delegate

A delegate is a reference to a method. Just like you can create a reference to an instance:

MyClass instance = myFactory.GetInstance();

You can use a delegate to create an reference to a method:

Action myMethod = myFactory.GetInstance;

Now that you have this reference to a method, you can call the method via the reference:

MyClass instance = myMethod();

But why would you? You can also just call myFactory.GetInstance() directly. In this case you can. However, there are many cases to think about where you don't want the rest of the application to have knowledge of myFactory or to call myFactory.GetInstance() directly.

An obvious one is if you want to be able to replace myFactory.GetInstance() into myOfflineFakeFactory.GetInstance() from one central place (aka factory method pattern).

Factory method pattern

So, if you have a TheOtherClass class and it needs to use the myFactory.GetInstance(), this is how the code will look like without delegates (you'll need to let TheOtherClass know about the type of your myFactory):

TheOtherClass toc;
//...
toc.SetFactory(myFactory);


class TheOtherClass
{
   public void SetFactory(MyFactory factory)
   {
      // set here
   }

}

If you'd use delegates, you don't have to expose the type of my factory:

TheOtherClass toc;
//...
Action factoryMethod = myFactory.GetInstance;
toc.SetFactoryMethod(factoryMethod);


class TheOtherClass
{
   public void SetFactoryMethod(Action factoryMethod)
   {
      // set here
   }

}

Thus, you can give a delegate to some other class to use, without exposing your type to them. The only thing you're exposing is the signature of your method (how many parameters you have and such).

"Signature of my method", where did I hear that before? O yes, interfaces!!! interfaces describe the signature of a whole class. Think of delegates as describing the signature of only one method!

Another large difference between an interface and a delegate is that when you're writing your class, you don't have to say to C# "this method implements that type of delegate". With interfaces, you do need to say "this class implements that type of an interface".

Further, a delegate reference can (with some restrictions, see below) reference multiple methods (called MulticastDelegate). This means that when you call the delegate, multiple explicitly-attached methods will be executed. An object reference can always only reference to one object.

The restrictions for a MulticastDelegate are that the (method/delegate) signature should not have any return value (void) and the keywords out and ref is not used in the signature. Obviously, you can't call two methods that return a number and expect them to return the same number. Once the signature complies, the delegate is automatically a MulticastDelegate.

Event

Events are just properties (like the get;set; properties to instance fields) which expose subscription to the delegate from other objects. These properties, however, don't support get;set;. Instead, they support add; remove;

So you can have:

    Action myField;

    public event Action MyProperty
    {
        add { myField += value; }
        remove { myField -= value; }
    }

Usage in UI (WinForms,WPF,UWP So on)

So, now we know that a delegate is a reference to a method and that we can have an event to let the world know that they can give us their methods to be referenced from our delegate, and we are a UI button, then: we can ask anyone who is interested in whether I was clicked, to register their method with us (via the event we exposed). We can use all those methods that were given to us and reference them by our delegate. And then, we'll wait and wait.... until a user comes and clicks on that button, then we'll have enough reason to invoke the delegate. And because the delegate references all those methods given to us, all those methods will be invoked. We don't know what those methods do, nor we know which class implements those methods. All we do care about is that someone was interested in us being clicked, and gave us a reference to a method that complied with our desired signature.

Java

Languages like Java don't have delegates. They use interfaces instead. The way they do that is to ask anyone who is interested in 'us being clicked', to implement a certain interface (with a certain method we can call), then give us the whole instance that implements the interface. We keep a list of all objects implementing this interface and can call their 'certain method we can call' whenever we get clicked.

I don't think anyone has mentioned this: Use of alloca in a function will hinder or disable some optimizations that could otherwise be applied in the function, since the compiler cannot know the size of the function's stack frame.

For instance, a common optimization by C compilers is to eliminate use of the frame pointer within a function, frame accesses are made relative to the stack pointer instead; so there's one more register for general use. But if alloca is called within the function, the difference between sp and fp will be unknown for part of the function, so this optimization cannot be done.

Given the rarity of its use, and its shady status as a standard function, compiler designers quite possibly disable any optimization that might cause trouble with alloca, if would take more than a little effort to make it work with alloca.

UPDATE: Since variable-length local arrays have been added to C, and since these present very similar code-generation issues to the compiler as alloca, I see that 'rarity of use and shady status' does not apply to the underlying mechanism; but I would still suspect that use of either alloca or VLA tends to compromise code generation within a function that uses them. I would welcome any feedback from compiler designers.

For Python 3, you need:

list_of_dict_values = list(dict_name.values())

I also had added on or extended additional columns into my AspNetUsers table. When I wanted to simply view this data I found many examples like the code above with "Extensions" etc... This really amazed me that you had to write all those lines of code just to get a couple values from the current users.

It turns out that you can query the AspNetUsers table like any other table:

 ApplicationDbContext db = new ApplicationDbContext();
 var user = db.Users.Where(x => x.UserName == User.Identity.Name).FirstOrDefault();

Use dict.items(); it can be as simple as following:

ship = collections.OrderedDict(ship.items())

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.

I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:

seq 1 500000 | while read digit; do
    touch $(printf "abigfilename%06d\n" $digit);
done

And we note:

$ getconf ARG_MAX
2097152

Note however I can do this:

$ echo * > /dev/null

But this fails:

$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long

I can run a for loop:

$ for f in *; do :; done

which is another shell builtin.

Careful reading of the documentation for ARG_MAX states, Maximum length of argument to the exec functions. This means: Without calling exec, there is no ARG_MAX limitation. So it would explain why shell builtins are not restricted by ARG_MAX.

And indeed, I can ls my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX is working as advertised: the exec is failing with more than ARG_MAX characters on the argument list- including, it should be noted, the environment data.

Although it is a bit strange, but the notifyDataSetChanged does not really work without setting new values to adapter. So, you should do:

array = getNewItems();                    
((MyAdapter) mAdapter).setValues(array);  // pass the new list to adapter !!!
mAdapter.notifyDataSetChanged();       

This has worked for me.

With Oracle you could use analytic functions:

select town, count(town), sum(count(town)) over () total_count from user
group by town

Your other options is to use a subquery:

select town, count(town), (select count(town) from user) as total_count from user
group by town

Removing a Single Attribute on a Single File

See Bavarious's answer.

To Remove All Extended Attributes On a Single File

Use xattr with the -c flag to "clear" the attributes:

xattr -c yourfile.txt

To Remove All Extended Attributes On Many Files

To recursively remove extended attributes on all files in a directory, combine the -c "clear" flag with the -r recursive flag:

xattr -rc /path/to/directory

A Tip for Mac OS X Users

Have a long path with spaces or special characters?

Open Terminal.app and start typing xattr -rc, include a trailing space, and then then drag the file or folder to the Terminal.app window and it will automatically add the full path with proper escaping.

In order to include the number of row index "columns" in your total shape I would personally add together the number of columns df.columns.size with the attribute pd.Index.nlevels/pd.MultiIndex.nlevels:

Set up dummy data

import pandas as pd

flat_index = pd.Index([0, 1, 2])
multi_index = pd.MultiIndex.from_tuples([("a", 1), ("a", 2), ("b", 1), names=["letter", "id"])

columns = ["cat", "dog", "fish"]

data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flat_df = pd.DataFrame(data, index=flat_index, columns=columns)
multi_df = pd.DataFrame(data, index=multi_index, columns=columns)

# Show data
# -----------------
# 3 columns, 4 including the index
print(flat_df)
    cat  dog  fish
id                
0     1    2     3
1     4    5     6
2     7    8     9

# -----------------
# 3 columns, 5 including the index
print(multi_df)
           cat  dog  fish
letter id                
a      1     1    2     3
       2     4    5     6
b      1     7    8     9

Writing our process as a function:

def total_ncols(df, include_index=False):
    ncols = df.columns.size
    if include_index is True:
        ncols += df.index.nlevels
    return ncols

print("Ignore the index:")
print(total_ncols(flat_df), total_ncols(multi_df))

print("Include the index:")
print(total_ncols(flat_df, include_index=True), total_ncols(multi_df, include_index=True))

This prints:

Ignore the index:
3 3

Include the index:
4 5

If you want to only include the number of indices if the index is a pd.MultiIndex, then you can throw in an isinstance check in the defined function.

As an alternative, you could use df.reset_index().columns.size to achieve the same result, but this won't be as performant since we're temporarily inserting new columns into the index and making a new index before getting the number of columns.

At the Method Level

1.When the annotation is used at the method level it indicates the purpose of that method is to add one or more model attributes

@ModelAttribute
public void addAttributes(Model model) {
model.addAttribute("india", "india");
}

At the Method Argument 1. When used as a method argument, it indicates the argument should be retrieved from the model. When not present and should be first instantiated and then added to the model and once present in the model, the arguments fields should be populated from all request parameters that have matching names So, it binds the form data with a bean.

 @RequestMapping(value = "/addEmployee", method = RequestMethod.POST)
  public String submit(@ModelAttribute("employee") Employee employee) {
  return "employeeView";
  }

This post is just to mention an additional option. In case you need to set custom R libs in your Linux shell script you may easily do so by

export R_LIBS="~/R/lib"

See R admin guide on complete list of options.

You could try hbase api methods!

org.apache.hadoop.hbase.client.coprocessor.AggregationClient

you can use the collector like this

  Stream<String> io = Stream.of("foo" , "lan" , "mql");
  io.collect(Collectors.toCollection(ArrayList<String>::new));

You can update the accepted answer with the iter_lines method of requests if the file is very large

import csv
import requests

CSV_URL = 'http://samplecsvs.s3.amazonaws.com/Sacramentorealestatetransactions.csv'

with requests.Session() as s:
    download = s.get(CSV_URL)

    line_iterator = (x.decode('utf-8') for x in download.iter_lines(decode_unicode=True))

    cr = csv.reader(line_iterator, delimiter=',')
    my_list = list(cr)
    for row in my_list:
        print(row)

git branch -a - All branches.

git branch -r - Remote branches only.

git branch -l or git branch - Local branches only.

try this

    $("#mprDetailDataTable tr:gt(0)").each(function () {
        var this_row = $(this);
        var productId = $.trim(this_row.find('td:eq(0)').html());//td:eq(0) means first td of this row
        var product = $.trim(this_row.find('td:eq(1)').html())
        var Quantity = $.trim(this_row.find('td:eq(2)').html())
    });

To position horizontally center you can say width: 50%; margin: auto;. As far as I know, that's cross browser. For vertical alignment you can try vertical-align:middle;, but it may only work in relation to text. It's worth a try though.

An other way to get only the filename without querystring is by using parse_url and basename functions :

$parts = parse_url("http://example.com/foo/bar/baz/file.php?a=b&c=d");
$filename = basename($parts["path"]); // this will return 'file.php'

There are two possible solutions:

• Use a boolean mask, then use df.loc[mask]
• Set the date column as a DatetimeIndex, then use df[start_date : end_date]

Using a boolean mask:

Ensure df['date'] is a Series with dtype datetime64[ns]:

df['date'] = pd.to_datetime(df['date'])  

Make a boolean mask. start_date and end_date can be datetime.datetimes, np.datetime64s, pd.Timestamps, or even datetime strings:

#greater than the start date and smaller than the end date
mask = (df['date'] > start_date) & (df['date'] <= end_date)

Select the sub-DataFrame:

df.loc[mask]

or re-assign to df

df = df.loc[mask]

For example,

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.random((200,3)))
df['date'] = pd.date_range('2000-1-1', periods=200, freq='D')
mask = (df['date'] > '2000-6-1') & (df['date'] <= '2000-6-10')
print(df.loc[mask])

yields

            0         1         2       date
153  0.208875  0.727656  0.037787 2000-06-02
154  0.750800  0.776498  0.237716 2000-06-03
155  0.812008  0.127338  0.397240 2000-06-04
156  0.639937  0.207359  0.533527 2000-06-05
157  0.416998  0.845658  0.872826 2000-06-06
158  0.440069  0.338690  0.847545 2000-06-07
159  0.202354  0.624833  0.740254 2000-06-08
160  0.465746  0.080888  0.155452 2000-06-09
161  0.858232  0.190321  0.432574 2000-06-10

Using a DatetimeIndex:

If you are going to do a lot of selections by date, it may be quicker to set the date column as the index first. Then you can select rows by date using df.loc[start_date:end_date].

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.random((200,3)))
df['date'] = pd.date_range('2000-1-1', periods=200, freq='D')
df = df.set_index(['date'])
print(df.loc['2000-6-1':'2000-6-10'])

yields

                   0         1         2
date                                    
2000-06-01  0.040457  0.326594  0.492136    # <- includes start_date
2000-06-02  0.279323  0.877446  0.464523
2000-06-03  0.328068  0.837669  0.608559
2000-06-04  0.107959  0.678297  0.517435
2000-06-05  0.131555  0.418380  0.025725
2000-06-06  0.999961  0.619517  0.206108
2000-06-07  0.129270  0.024533  0.154769
2000-06-08  0.441010  0.741781  0.470402
2000-06-09  0.682101  0.375660  0.009916
2000-06-10  0.754488  0.352293  0.339337

While Python list indexing, e.g. seq[start:end] includes start but not end, in contrast, Pandas df.loc[start_date : end_date] includes both end-points in the result if they are in the index. Neither start_date nor end_date has to be in the index however.

Also note that pd.read_csv has a parse_dates parameter which you could use to parse the date column as datetime64s. Thus, if you use parse_dates, you would not need to use df['date'] = pd.to_datetime(df['date']).

In Place of using this

MsgBox(json.SelectToken("Venue").SelectToken("ID"))

You can also use

MsgBox(json.SelectToken("Venue.ID"))

TimezoneDb provides a free API: http://timezonedb.com/api

GenoNames also has a RESTful API available to get the current time for a given location: http://www.geonames.org/export/ws-overview.html.

You can use Greenwich, UK if you'd like GMT.

I like this better than any of the previous answers. It shows how to use the YAML format and lets you use a variable to specify the bucket.

    - PolicyName: "AllowIncomingBucket"
      PolicyDocument:

              - !Ref S3BucketArn
              - !Join ["/", [!Ref S3BucketArn, '*']]

If you are loading the XML file from a remote location, I would check to see if the file is actually being downloaded correctly using a sniffer like Fiddler.

I wrote a quick console app to run your code and parse the file and it works fine for me.

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

Now with Java EE 7 you can find the resource more easily with

InputStream resource = getServletContext().getResourceAsStream("/WEB-INF/my.json");

A pem file contains the certificate and the private key. It depends on the format your certificate/key are in, but probably it's as simple as this:

cat server.crt server.key > server.pem

Solution in Swift 3.1, After connecting your textfields IBOutlets set your textfields delegate in viewDidLoad, And then navigate your action in textFieldShouldReturn

class YourViewController: UIViewController,UITextFieldDelegate {

        @IBOutlet weak var passwordTextField: UITextField!
        @IBOutlet weak var phoneTextField: UITextField!

        override func viewDidLoad() {
            super.viewDidLoad()
            self.passwordTextField.delegate = self
            self.phoneTextField.delegate = self
            // Set your return type
            self.phoneTextField.returnKeyType = .next
            self.passwordTextField.returnKeyType = .done
        }

        func textFieldShouldReturn(_ textField: UITextField) -> Bool{
            if textField == self.phoneTextField {
                self.passwordTextField.becomeFirstResponder()
            }else if textField == self.passwordTextField{
                // Call login api
                self.login()
            }
            return true
        }

    }

This works for me:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- NOTE: order is important (the first matching state(s) is what is rendered) -->
    <item 
        android:state_selected="true" 
        android:drawable="@drawable/info_icon_solid_with_shadow" />
    <item 
        android:drawable="@drawable/info_icon_outline_with_shadow" />
 </selector>

And then in java:

//assign the image in code (or you can do this in your layout xml with the src attribute)
imageButton.setImageDrawable(getBaseContext().getResources().getDrawable(R.drawable....));

//set the click listener
imageButton.setOnClickListener(new OnClickListener() {

    public void onClick(View button) {
        //Set the button's appearance
        button.setSelected(!button.isSelected());

        if (button.isSelected()) {
            //Handle selected state change
        } else {
            //Handle de-select state change
        }

    }

});

For smooth transition you can also mention animation time:

<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="@android:integer/config_mediumAnimTime">

Forgot to relate to the first code snippet. I wouldn't use forEach at all. Since you are collecting the elements of the Stream into a List, it would make more sense to end the Stream processing with collect. Then you would need peek in order to set the ID.

List<Entry> updatedEntries = 
    entryList.stream()
             .peek(e -> e.setTempId(tempId))
             .collect (Collectors.toList());

For the second snippet, forEach can execute multiple expressions, just like any lambda expression can :

entryList.forEach(entry -> {
  if(entry.getA() == null){
    printA();
  }
  if(entry.getB() == null){
    printB();
  }
  if(entry.getC() == null){
    printC();
  }
});

However (looking at your commented attempt), you can't use filter in this scenario, since you will only process some of the entries (for example, the entries for which entry.getA() == null) if you do.

I'm not an expert, but I guess in sed you'd first need to append the next line into the pattern space, bij using "N". From the section "Multiline Pattern Space" in "Advanced sed Commands" of the book sed & awk (Dale Dougherty and Arnold Robbins; O'Reilly 1997; page 107 in the preview):

The multiline Next (N) command creates a multiline pattern space by reading a new line of input and appending it to the contents of the pattern space. The original contents of pattern space and the new input line are separated by a newline. The embedded newline character can be matched in patterns by the escape sequence "\n". In a multiline pattern space, the metacharacter "^" matches the very first character of the pattern space, and not the character(s) following any embedded newline(s). Similarly, "$" matches only the final newline in the pattern space, and not any embedded newline(s). After the Next command is executed, control is then passed to subsequent commands in the script.

From man sed:

[2addr]N

Append the next line of input to the pattern space, using an embedded newline character to separate the appended material from the original contents. Note that the current line number changes.

I've used this to search (multiple) badly formatted log files, in which the search string may be found on an "orphaned" next line.

For special permissions, such as android.Manifest.permission.PACKAGE_USAGE_STATS used AppOpsManager:
Kotlin

private fun hasPermission(permission:String, permissionAppOpsManager:String): Boolean {
    var granted = false
    if (VERSION.SDK_INT >= VERSION_CODES.M) {
        // requires kitkat
        val appOps = applicationContext!!.getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager

        // requires lollipop
        val mode = appOps.checkOpNoThrow(permissionAppOpsManager,
                              android.os.Process.myUid(), applicationContext!!.packageName)

        if (mode == AppOpsManager.MODE_DEFAULT) {
            granted = applicationContext!!.checkCallingOrSelfPermission(permission) == PackageManager.PERMISSION_GRANTED
        } else {
            granted = mode == AppOpsManager.MODE_ALLOWED
        }
    }

    return granted
}

and anywhere in code:

val permissionAppOpsManager = AppOpsManager.OPSTR_GET_USAGE_STATS
val permission = android.Manifest.permission.PACKAGE_USAGE_STATS
val permissionActivity = Settings.ACTION_USAGE_ACCESS_SETTINGS

if (hasPermission(permission, permissionAppOpsManager)) {
    Timber.i("has permission: $permission")
    // do here what needs permission
} else {
    Timber.e("has no permission: $permission")
    // start activity to get permission
    startActivity(Intent(permissionActivity))
}

Other permissions you can get with TedPermission library

The Apache module PHP version might for some odd reason not be picking up the php.ini file as the CLI version I'd suggest having a good look at:

• Any differences in the .ini files that differ between php -i and phpinfo() via a web page*
• If there are no differences then to look at the permissions of mysql.so and the .ini files but I think that Apache parses these as the root user

To be really clear here, don't go searching for php.ini files on the file system, have a look at what PHP says that it's looking at

Using Guava library:

int size = Iterators.size(iterator);

Internally it just iterates over all elements so its just for convenience.

This answer is for the impatient/ have deadlines to meet to, only a part/simple explanation is below:

• in C++, you can have same name in class via overloading (for example, since they are all same name can't be exported as-is from dll, etc.) solution to these problems is they are converted to different strings (called symbols), symbols accounts the name of function, also the arguments, so each of these functions even with same name, can be uniquely identified (also called, name mangling)
• in C, you don't have overloading, the function name is unique (so, a separate string for identifying the a function name uniquely is not required, so symbol is function name itself)

So
in C++, with name mangling uniquely identities each function
in C, even without name mangling uniquely identities each function

To change the behaviour of C++, that is, to specify that name mangling should not happen for a particular function, you can use extern "C" before the function name, for whatever reason, like exporting a function with a specific name from a dll, for use by its clients.

Make use of Android Volly library as much as possible. It maps your JSON reponse in respective class objects. You can add getter setter for that response model objects. And then you can access these JSON values/parameter using .operator like normal JAVA Object. It makes response handling very simple.

import java.util.Scanner;
class my{
public static void main(String args[])
{
    Scanner x=new Scanner(System.in);
    double a,b,c=0,d;
    d=1;
    d=d/10;
    int e,z=0;
    System.out.print("Enter no:");
    a=x.nextInt();

    for(b=1;b<=a/2;b++)
    {
        if(b*b==a)
        {
            c=b;
            break;
        }
        else
        {
            if(b*b>a)
            break;
        }
    } 
    b--;
    if(c==0)
    {
       for(e=1;e<=15;e++)
        {
            while(b*b<=a && z==0)
            {
                if(b*b==a){c=b;z=1;}
                else
                {
                    b=b+d;          //*d==0.1 first time*//
                    if(b*b>=a){z=1;b=b-d;}
                }
            }
            d=d/10;
            z=0;
        }
        c=b;
    }

        System.out.println("Squre root="+c);

C# 8 now (since 2019) supports Ranges which allows you to achieve Slice much easier (similar to JS syntax):

var array = new int[] { 1, 2, 3, 4, 5 };
var slice1 = array[2..^3];    // array[new Range(2, new Index(3, fromEnd: true))]
var slice2 = array[..^3];     // array[Range.EndAt(new Index(3, fromEnd: true))]
var slice3 = array[2..];      // array[Range.StartAt(2)]
var slice4 = array[..];       // array[Range.All]

You can use ranges instead of the well known LINQ functions: Skip(), Take(), Count().

Please check https://www.sqlite.org/lang_altertable.html#otheralter

The only schema altering commands directly supported by SQLite are the "rename table" and "add column" commands shown above. However, applications can make other arbitrary changes to the format of a table using a simple sequence of operations. The steps to make arbitrary changes to the schema design of some table X are as follows:

1. If foreign key constraints are enabled, disable them using PRAGMA foreign_keys=OFF.
2. Start a transaction.
3. Remember the format of all indexes and triggers associated with table X. This information will be needed in step 8 below. One way to do this is to run a query like the following: SELECT type, sql FROM sqlite_master WHERE tbl_name='X'.
4. Use CREATE TABLE to construct a new table "new_X" that is in the desired revised format of table X. Make sure that the name "new_X" does not collide with any existing table name, of course.
5. Transfer content from X into new_X using a statement like: INSERT INTO new_X SELECT ... FROM X.
6. Drop the old table X: DROP TABLE X.
7. Change the name of new_X to X using: ALTER TABLE new_X RENAME TO X.
8. Use CREATE INDEX and CREATE TRIGGER to reconstruct indexes and triggers associated with table X. Perhaps use the old format of the triggers and indexes saved from step 3 above as a guide, making changes as appropriate for the alteration.
9. If any views refer to table X in a way that is affected by the schema change, then drop those views using DROP VIEW and recreate them with whatever changes are necessary to accommodate the schema change using CREATE VIEW.
10. If foreign key constraints were originally enabled then run PRAGMA foreign_key_check to verify that the schema change did not break any foreign key constraints.
11. Commit the transaction started in step 2.
12. If foreign keys constraints were originally enabled, reenable them now.

The procedure above is completely general and will work even if the schema change causes the information stored in the table to change. So the full procedure above is appropriate for dropping a column, changing the order of columns, adding or removing a UNIQUE constraint or PRIMARY KEY, adding CHECK or FOREIGN KEY or NOT NULL constraints, or changing the datatype for a column, for example.

You can use the module called win32clipboard, which is part of pywin32.

Here is an example that first sets the clipboard data then gets it:

import win32clipboard

# set clipboard data
win32clipboard.OpenClipboard()
win32clipboard.EmptyClipboard()
win32clipboard.SetClipboardText('testing 123')
win32clipboard.CloseClipboard()

# get clipboard data
win32clipboard.OpenClipboard()
data = win32clipboard.GetClipboardData()
win32clipboard.CloseClipboard()
print data

An important reminder from the documentation:

When the window has finished examining or changing the clipboard, close the clipboard by calling CloseClipboard. This enables other windows to access the clipboard. Do not place an object on the clipboard after calling CloseClipboard.

Try rejson-py which is relatively new since 2017. Look at this introduction.

from rejson import Client, Path

rj = Client(host='localhost', port=6379)

# Set the key `obj` to some object
obj = {
    'answer': 42,
    'arr': [None, True, 3.14],
    'truth': {
        'coord': 'out there'
    }
}
rj.jsonset('obj', Path.rootPath(), obj)

# Get something
print 'Is there anybody... {}?'.format(
    rj.jsonget('obj', Path('.truth.coord'))
)

# Delete something (or perhaps nothing), append something and pop it
rj.jsondel('obj', Path('.arr[0]'))
rj.jsonarrappend('obj', Path('.arr'), 'something')
print '{} popped!'.format(rj.jsonarrpop('obj', Path('.arr')))

# Update something else
rj.jsonset('obj', Path('.answer'), 2.17)

I have faced this type of error. to call a function from the razor.

public ActionResult EditorAjax(int id, int? jobId, string type = ""){}

solved that by changing the line

from

<a href="/ScreeningQuestion/EditorAjax/5&jobId=2&type=additional" /> 

to

<a href="/ScreeningQuestion/EditorAjax/?id=5&jobId=2&type=additional" />

where my route.config is

routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }, new string[] { "RPMS.Controllers" } // Parameter defaults
        );

i believe what you're looking for is the str.encode("string-escape") function. For example, if you have a variable that you want to 'raw string':

a = '\x89'
a.encode('unicode_escape')
'\\x89'

Note: Use string-escape for python 2.x and older versions

I was searching for a similar solution and found the solution via: casting raw strings python

This worked for me. adding two dots and slash.

body{
    background: url(../images/yourimage.png);
}

You can do this:

describe EVENT_LOG

or

desc EVENT_LOG

Note: only applicable if you know the table name and specifically for Oracle.

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

If you are using:

tstart = clock();

// ...do something...

tend = clock();

Then you will need the following to get time in seconds:

time = (tend - tstart) / (double) CLOCKS_PER_SEC;

What's typically meant by 32-bit or 64-bit machine is the size of the externally visible ("architected") general-purpose integer registers.

This has very little to do with how the hardware is built though. For example, let's consider the (long obsolete) Intel Pentium Pro. It's normally considered a "32-bit" processor, even though it supports up to 36-bit physical addresses, has a 64-bit wide data bus, and internally computations on all supported operand types are carried out in a single set of registers (which are therefore 80 bits wide, to support the largest floating point type).

At least in the case of Intel processors, even though larger physical addressing has been available for a long time, the largest amount of memory directly visible within the address space of any one process on a 32-bit processor is also limited to 4 gigabytes (32-bit addressing). The 36-bit physical addressing allows addressing up to 64 gigabytes of RAM, but only 4 gigabytes of that can be directly visible at any given time.

The change to 64-bit machines mostly involved changing what was made visible to the user (or to code at the assembly language level). Again, what you see is rarely identical to what's real. For example, most 64-bit code sees pointers/addresses as being 64 bits, but actual processors don't support that large of addresses. Current CPUs support 48-bit virtual addresses, and (at least as far as I've noticed) a maximum of 40 bits of physical addressing. On the other hand, they're designed so in the future, when larger memory becomes practical, they can extend the physical addressing out to 48 bits without affecting software at all. Even when they increase the 48-bit virtual addressing, in a typical case it'll only affect a small amount of the operating system kernel (normal code is unaffected, because it already assumed addresses are 64 bits).

So, no: a 64-bit machine does not really support up to 64 bits of physical addressing, but most typical 64-bit software should remain compatible with a future processor that did support directly addressing that much RAM.

Just in case someone pulls their hair out with this problem like I did today, I couldn't resolve this error until I changed

spring.jpa.hibernate.dll-auto=create

to

spring.jpa.properties.hibernate.hbm2ddl.auto=create

<meta name="viewport" content="width=device-width, minimum-scale=1, maximum-scale=1">

In standard SQL this type of update looks like:

update a
   set a.firstfield ='BIT OF TEXT' + b.something
  from file1 a
  join file2 b
    on substr(a.firstfield,10,20) = 
       substr(b.anotherfield,1,10)
 where a.firstfield like 'BLAH%' 

With minor syntactic variations this type of thing will work on Oracle or SQL Server and (although I don't have a DB/2 instance to hand to test) will almost certainly work on DB/2.

Here's a workaround. If you want to copy everything from A that does not already exist in B:

Copy A to a new directory C. Copy B to C, overwriting anything that overlaps with A. Copy C to B.

That means you must install simplejson. On newer versions of python, it was included by default into python's distribution, and renamed to json. So if you are on python 2.6+ you should change all instances of simplejson to json.

For a quick fix you could also edit the file and change the line:

import simplejson

to:

import json as simplejson

and hopefully things will work.

Like with SQL Server Management Studio (already explained), it is also possible with Datagrip as explained here.

1. Right-click an SQL statement, and select Explain plan.
2. In the Output pane, click Plan.
3. By default, you see the tree representation of the query. To see the query plan, click the Show Visualization icon, or press Ctrl+Shift+Alt+U

Please keep in mind: this is just a JavaScript thing and has nothing to do with Angular JS. So don't be confused about the magical '$' sign ;)

The main problem is that this is an hierarchical structure.

console.log($scope.life.meaning);  // <-- Nope! This is undefined.
=> a.b.c

This is undefined because "$scope.life" is not existing but the term above want to solve "meaning".

A solution should be

var the_string = 'lifeMeaning';
$scope[the_string] = 42;
console.log($scope.lifeMeaning);
console.log($scope['lifeMeaning']);

or with a little more efford.

var the_string_level_one = 'life';
var the_string_level_two = the_string_level_one + '.meaning';
$scope[the_string_level_two ] = 42;
console.log($scope.life.meaning);
console.log($scope['the_string_level_two ']);

Since you can access a structural objecte with

var a = {};
a.b = "ab";
console.log(a.b === a['b']);

There are several good tutorials about this which guide you well through the fun with JavaScript.

There is something about the

$scope.$apply();
do...somthing...bla...bla

Go and search the web for 'angular $apply' and you will find information about the $apply function. And you should use is wisely more this way (if you are not alreay with a $apply phase).

$scope.$apply(function (){
    do...somthing...bla...bla
})

 $("#file-upload").change(function () {

    var validExtensions = ["jpg","pdf","jpeg","gif","png"]
    var file = $(this).val().split('.').pop();
    if (validExtensions.indexOf(file) == -1) {
        alert("Only formats are allowed : "+validExtensions.join(', '));
    }

});

Well the first and second queries may yield different results because a LEFT JOIN includes all records from the first table, even if there are no corresponding records in the right table.

From the bash man page:

Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard.

So you can do this:

echo $'hello\tworld'

Another easy way to do this is by using the following syntax to iterate through the object, keeping access to the key and value:

for(var key in object){
  console.log(key + ' - ' + object[key])
}

so for yours:

for(var key in obj){
  console.log(key + ' - ' + obj[key])
}

ugly but efficient

stringstream.str() returns a temporary string object that's destroyed at the end of the full expression. If you get a pointer to a C string from that (stringstream.str().c_str()), it will point to a string which is deleted where the statement ends. That's why your code prints garbage.

You could copy that temporary string object to some other string object and take the C string from that one:

const std::string tmp = stringstream.str();
const char* cstr = tmp.c_str();

Note that I made the temporary string const, because any changes to it might cause it to re-allocate and thus render cstr invalid. It is therefor safer to not to store the result of the call to str() at all and use cstr only until the end of the full expression:

use_c_str( stringstream.str().c_str() );

Of course, the latter might not be easy and copying might be too expensive. What you can do instead is to bind the temporary to a const reference. This will extend its lifetime to the lifetime of the reference:

{
  const std::string& tmp = stringstream.str();   
  const char* cstr = tmp.c_str();
}

IMO that's the best solution. Unfortunately it's not very well known.

https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.sort_values.html

I don't think you should ever provide the False value in square brackets (ever), also the column values when they are more than one, then only they are provided as a list! Not like ['one'].

test = df.sort_values(by='one', ascending = False)

There is a package called yum-utils that builds on YUM and contains a tool called repoquery that can do this.

$ repoquery --help | grep -E "list\ files" 
  -l, --list            list files in this package/group

Combined into one example:

$ repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

On at least one RH system, with rpm v4.8.0, yum v3.2.29, and repoquery v0.0.11, repoquery -l rpm prints nothing.

If you are having this issue, try adding the --installed flag: repoquery --installed -l rpm.

DNF Update:

To use dnf instead of yum-utils, use the following command:

$ dnf repoquery -l time
/usr/bin/time
/usr/share/doc/time-1.7
/usr/share/doc/time-1.7/COPYING
/usr/share/doc/time-1.7/NEWS
/usr/share/doc/time-1.7/README
/usr/share/info/time.info.gz

Try this:

document.frames["myiframe"].onload = function(){
   alert("Hello World");
}

int [] SouceArray1 = new int[] {2,1,3};
int [] SourceArray2 = new int[] {4,5,6};
int [] targetArray = new int [SouceArray1.Length + SourceArray2.Length];
SouceArray1.CopyTo(targetArray,0);
SourceArray2.CopyTo(targetArray,SouceArray1.Length) ; 
foreach (int i in targetArray) Console.WriteLine(i + " ");  

Using the above code two Arrays can be easily merged.

First step: write an extension method to find out if an input is prime

public static bool isPrime(this int number ) {

    for (int i = 2; i < number; i++) { 
        if (number % i == 0) { 
            return false; 
        } 
    }

    return true;   
}

2 step: write the method that will print all prime numbers that are between 0 and the number input

public static void getAllPrimes(int number)
{
    for (int i = 0; i < number; i++)
    {
        if (i.isPrime()) Console.WriteLine(i);
    }
}

You can simply print exception.ToString() -- that will also include the full text for all the nested InnerExceptions.

Try this:

var curHeight;
var curWidth;

function getImgSize(imgSrc)
{
var newImg = new Image();
newImg.src = imgSrc;
curHeight = newImg.height;
curWidth = newImg.width;

}

I know it's not an exact answer to the OP, but as answers have already be given...

Do you really need to do this in PHP ?
What I mean is : if you need to convert a lot of images, doing it in PHP might not be the best way : you'll be confronted to memory_limit, max_execution_time, ...

I would also say GD might not get you the best quality/size ratio ; but not sure about that (if you do a comparison between GD and other solutions, I am very interested by the results ;-) )

Another approach, not using PHP, would be to use Image Magick via the command line (and not as a PHP extension like other people suggested)

You'd have to write a shell-script that goes through all .png files, and gives them to either

• convert to create a new .jpg file for each .png file
• or mogrify to directly work on the original file and override it.

As a sidenote : if you are doing this directly on your production server, you could put some sleep time between bunches of conversions, to let it cool down a bit sometimes ^^

I've use the shell script + convert/mogrify a few times (having them run for something like 10 hours one time), and they do the job really well :-)

One line solution:

const useForceUpdate = () => useState()[1];

useState returns a pair of values: the current state and a function that updates it - state and setter, here we are using only the setter in order to force re-render.

You are comparing two objects for equality. The snippet:

if (obj == this) {     return true; } 

is a quick test that can be read

"If the object I'm comparing myself to is me, return true"

. You usually see this happen in equals methods so they can exit early and avoid other costly comparisons.

https://php.net/manual/en/function.pathinfo.php

pathinfo($path, PATHINFO_FILENAME);

Simple functional test: https://ideone.com/POhIDC

This post has a method to achieve this

from (zvrba) You can do it by redirecting the output to a file first. For example:

echo zz > bla.txt
set /p VV=<bla.txt
echo %VV%

Swift 4: Another example using Unit Tests which only works with ===

Note: Test below fails with ==, works with ===

func test_inputTextFields_Delegate_is_ViewControllerUnderTest() {

        //instantiate viewControllerUnderTest from Main storyboard
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        viewControllerUnderTest = storyboard.instantiateViewController(withIdentifier: "StoryBoardIdentifier") as! ViewControllerUnderTest 
        let _ = viewControllerUnderTest.view

        XCTAssertTrue(viewControllerUnderTest.inputTextField.delegate === viewControllerUnderTest) 
    }

And the class being

class ViewControllerUnderTest: UIViewController, UITextFieldDelegate {
    @IBOutlet weak var inputTextField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        inputTextField.delegate = self
    }
}

The error in Unit Tests if you use == is, Binary operator '==' cannot be applied to operands of type 'UITextFieldDelegate?' and 'ViewControllerUnderTest!'

For completeness, we should include ConfigParser and configparser which are part of the standard library in Python 2 and 3, respectively. This module reads and writes to a config/ini file and (at least in Python 3) behaves in a lot of ways like a dictionary. It has the added benefit that you can store multiple dictionaries into separate sections of your config/ini file and recall them. Sweet!

Python 2.7.x example.

import ConfigParser

config = ConfigParser.ConfigParser()

dict1 = {'key1':'keyinfo', 'key2':'keyinfo2'}
dict2 = {'k1':'hot', 'k2':'cross', 'k3':'buns'}
dict3 = {'x':1, 'y':2, 'z':3}

# Make each dictionary a separate section in the configuration
config.add_section('dict1')
for key in dict1.keys():
    config.set('dict1', key, dict1[key])
   
config.add_section('dict2')
for key in dict2.keys():
    config.set('dict2', key, dict2[key])

config.add_section('dict3')
for key in dict3.keys():
    config.set('dict3', key, dict3[key])

# Save the configuration to a file
f = open('config.ini', 'w')
config.write(f)
f.close()

# Read the configuration from a file
config2 = ConfigParser.ConfigParser()
config2.read('config.ini')

dictA = {}
for item in config2.items('dict1'):
    dictA[item[0]] = item[1]

dictB = {}
for item in config2.items('dict2'):
    dictB[item[0]] = item[1]

dictC = {}
for item in config2.items('dict3'):
    dictC[item[0]] = item[1]

print(dictA)
print(dictB)
print(dictC)

Python 3.X example.

import configparser

config = configparser.ConfigParser()

dict1 = {'key1':'keyinfo', 'key2':'keyinfo2'}
dict2 = {'k1':'hot', 'k2':'cross', 'k3':'buns'}
dict3 = {'x':1, 'y':2, 'z':3}

# Make each dictionary a separate section in the configuration
config['dict1'] = dict1
config['dict2'] = dict2
config['dict3'] = dict3

# Save the configuration to a file
f = open('config.ini', 'w')
config.write(f)
f.close()

# Read the configuration from a file
config2 = configparser.ConfigParser()
config2.read('config.ini')

# ConfigParser objects are a lot like dictionaries, but if you really
# want a dictionary you can ask it to convert a section to a dictionary
dictA = dict(config2['dict1'] )
dictB = dict(config2['dict2'] )
dictC = dict(config2['dict3'])

print(dictA)
print(dictB)
print(dictC)

Console output

{'key2': 'keyinfo2', 'key1': 'keyinfo'}
{'k1': 'hot', 'k2': 'cross', 'k3': 'buns'}
{'z': '3', 'y': '2', 'x': '1'}

Contents of config.ini

[dict1]
key2 = keyinfo2
key1 = keyinfo

[dict2]
k1 = hot
k2 = cross
k3 = buns

[dict3]
z = 3
y = 2
x = 1

On Windows, the following steps should re-trigger the GitHub login window when git cloneing:

• Search start menu for "Credential Manager"
• Select "Windows Credentials"
• Delete any credentials related to Git or GitHub

You can use JVM args

java -Duser.country=ES -Duser.language=es -Duser.variant=Traditional_WIN

This code enumerates each sequence only once and uses Select(x => x) to hide the result to get a clean Linq-style extension method. Since it uses HashSet<T> its runtime is O(n + m) if the hashes are well distributed. Duplicate elements in either list are omitted.

public static IEnumerable<T> SymmetricExcept<T>(this IEnumerable<T> seq1,
    IEnumerable<T> seq2)
{
    HashSet<T> hashSet = new HashSet<T>(seq1);
    hashSet.SymmetricExceptWith(seq2);
    return hashSet.Select(x => x);
}

Search and Replace'

Ctrl + F Open find and replace dialog

Ctrl + F / Ctrl + Shift + K Find previous / find next occurrence of search term (close find window first).

Ctrl + H Search Workspace (Java Search, Task Search, and File Search).

Ctrl + J / Ctrl+Shift +J Incremental search forward / backwards. Type search term after pressing Ctrl+J, there is now search window Ctrl+shift+O Open a resource search dialog to find any class

If you want to use class, you can do this.

Helper.js

  function x(){}

  function y(){}

  export default class Helper{

    static x(){ x(); }

    static y(){ y(); }

  }

App.js

import Helper from 'helper.js';

Surprised I haven't seen this one yet. If you only need two splits, I highly recommend. . .

Series.str.partition

partition performs one split on the separator, and is generally quite performant.

df['row'].str.partition(' ')[[0, 2]]

       0                   2
0  00000       UNITED STATES
1  01000             ALABAMA
2  01001  Autauga County, AL
3  01003  Baldwin County, AL
4  01005  Barbour County, AL

If you need to rename the rows,

df['row'].str.partition(' ')[[0, 2]].rename({0: 'fips', 2: 'row'}, axis=1)

    fips                 row
0  00000       UNITED STATES
1  01000             ALABAMA
2  01001  Autauga County, AL
3  01003  Baldwin County, AL
4  01005  Barbour County, AL

If you need to join this back to the original, use join or concat:

df.join(df['row'].str.partition(' ')[[0, 2]])

pd.concat([df, df['row'].str.partition(' ')[[0, 2]]], axis=1)

                        row      0                   2
0       00000 UNITED STATES  00000       UNITED STATES
1             01000 ALABAMA  01000             ALABAMA
2  01001 Autauga County, AL  01001  Autauga County, AL
3  01003 Baldwin County, AL  01003  Baldwin County, AL
4  01005 Barbour County, AL  01005  Barbour County, AL

Try adding this at the end of your code:

import matplotlib.pyplot as plt

plt.title('add title here')

Note that if your canvas is statically declared you should use the width and height attributes, not the style, eg. this will work:

<canvas id="c" height="100" width="100" style="border:1px"></canvas>
<script>
    document.getElementById('c').width = 200;
</script>

But this will not work:

<canvas id="c" style="width: 100px; height: 100px; border:1px"></canvas>
<script>
    document.getElementById('c').width = 200;
</script>

You can combine the two functions; coerce to characters thence to numerics:

> fac <- factor(c("1","2","1","2"))
> as.numeric(as.character(fac))
[1] 1 2 1 2

Does not work, you have to do this:

if ( $("#your_select_id option[value='enter_value_here']").length == 0 ){
  alert("option doesn't exist!");
}

If you want to get it aligned to the right after the text looses focus you can try to use the direction modifier. This will show the right part of the text after loosing focus. e.g. useful if you want to show the file name in a large path.

input.rightAligned {_x000D_
  direction:ltr;_x000D_
  overflow:hidden;_x000D_
}_x000D_
input.rightAligned:not(:focus) {_x000D_
  direction:rtl;_x000D_
  text-align: left;_x000D_
  unicode-bidi: plaintext;_x000D_
  text-overflow: ellipsis;_x000D_
}

<form>_x000D_
    <input type="text" class="rightAligned" name="name" value="">_x000D_
</form>

The not selector is currently well supported : Browser support

I'm new to AngularJS and I came across this CORS problem, almost lost my mind! Luckily i found a way to fix this. So here it goes....

My problem was, when I use AngularJS $resource in sending API requests I'm getting this error message XMLHttpRequest cannot load http://website.com. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access. Yup, I already added callback="JSON_CALLBACK" and it didn't work.

What I did to fix it the problem, instead of using GET method or resorting to $http.get, I've used JSONP. Just replace GET method with JSONP and change the api response format to JSONP as well.

    myApp.factory('myFactory', ['$resource', function($resource) {

           return $resource( 'http://website.com/api/:apiMethod',
                        { callback: "JSON_CALLBACK", format:'jsonp' }, 
                        { 
                            method1: { 
                                method: 'JSONP', 
                                params: { 
                                            apiMethod: 'hello world'
                                        } 
                            },
                            method2: { 
                                method: 'JSONP', 
                                params: { 
                                            apiMethod: 'hey ho!'
                                        } 
                            }
            } );

    }]);

I hope someone find this helpful. :)

Use a cyclic scheduler. This gives you the ability to add regular maintenance times to check the correctness of critical data. The problem most often encountered is corruption of the stack. If your software is cyclical you can reinitialise the stack between cycles. Do not reuse the stacks for interrupt calls, setup a separate stack of each important interrupt call.

Similar to the Watchdog concept is deadline timers. Start a hardware timer before calling a function. If the function does not return before the deadline timer interrupts then reload the stack and try again. If it still fails after 3/5 tries you need reload from ROM.

Split your software into parts and isolate these parts to use separate memory areas and execution times (Especially in a control environment). Example: signal acquisition, prepossessing data, main algorithm and result implementation/transmission. This means a failure in one part will not cause failures through the rest of the program. So while we are repairing the signal acquisition the rest of tasks continues on stale data.

Everything needs CRCs. If you execute out of RAM even your .text needs a CRC. Check the CRCs regularly if you using a cyclical scheduler. Some compilers (not GCC) can generate CRCs for each section and some processors have dedicated hardware to do CRC calculations, but I guess that would fall out side of the scope of your question. Checking CRCs also prompts the ECC controller on the memory to repair single bit errors before it becomes a problem.

It's not possible to achieve the required level of control over presentation in a regular textarea.

If you're OK with that, try CodeMirror or Ace or Monaco (used in MS VSCode).

Pandas offer a great way to manipulate tables, as you can make binning easy (binning a dataframe in pandas in Python) and calculate statistics. Other thing that is great in pandas is the Panel class that you can join series of layers with different properties and combine it using groupby function.

Try the code below. Using core Java basic functions. It takes care of Strings with extension, and without extension (without the '.' character). The case of multiple '.' is also covered.

String str = "filename.xml";
if (!str.contains(".")) 
    System.out.println("File Name=" + str); 
else {
    str = str.substring(0, str.lastIndexOf("."));
    // Because extension is always after the last '.'
    System.out.println("File Name=" + str);
}

You can adapt it to work with null strings.

I've found an solution. I use an solution of Steve Gentile, jQuery and ASP.NET MVC – sending JSON to an Action – Revisited.

My ASP.NET MVC view code looks like:

function getplaceholders() {
        var placeholders = $('.ui-sortable');
        var results = new Array();
        placeholders.each(function() {
            var ph = $(this).attr('id');
            var sections = $(this).find('.sort');
            var section;

            sections.each(function(i, item) {
                var sid = $(item).attr('id');
                var o = { 'SectionId': sid, 'Placeholder': ph, 'Position': i };
                results.push(o);
            });
        });
        var postData = { widgets: results };
        var widgets = results;
        $.ajax({
            url: '/portal/Designer.mvc/SaveOrUpdate',
            type: 'POST',
            dataType: 'json',
            data: $.toJSON(widgets),
            contentType: 'application/json; charset=utf-8',
            success: function(result) {
                alert(result.Result);
            }
        });
    };

and my controller action is decorated with an custom attribute

[JsonFilter(Param = "widgets", JsonDataType = typeof(List<PageDesignWidget>))]
public JsonResult SaveOrUpdate(List<PageDesignWidget> widgets

Code for the custom attribute can be found here (the link is broken now).

Because the link is broken this is the code for the JsonFilterAttribute

public class JsonFilter : ActionFilterAttribute
{
    public string Param { get; set; }
    public Type JsonDataType { get; set; }
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (filterContext.HttpContext.Request.ContentType.Contains("application/json"))
        {
            string inputContent;
            using (var sr = new StreamReader(filterContext.HttpContext.Request.InputStream))
            {
                inputContent = sr.ReadToEnd();
            }
            var result = JsonConvert.DeserializeObject(inputContent, JsonDataType);
            filterContext.ActionParameters[Param] = result;
        }
    }
}

JsonConvert.DeserializeObject is from Json.NET

Link: Serializing and Deserializing JSON with Json.NET

Assuming you mean "file on a local filesystem" when you say .json file.

You'll need to save the json data formatted as jsonp, and use a file:// url to access it.

Your HTML will look like this:

<script src="file://c:\\data\\activity.jsonp"></script>
<script type="text/javascript">
  function updateMe(){
    var x = 0;
    var activity=jsonstr;
    foreach (i in activity) {
        date = document.getElementById(i.date).innerHTML = activity.date;
        event = document.getElementById(i.event).innerHTML = activity.event;
    }
  }
</script>

And the file c:\data\activity.jsonp contains the following line:

jsonstr = [ {"date":"July 4th", "event":"Independence Day"} ];

You can solve it very simple way just invoking the input. However, if you press Enter then the console will disapper again. Simply use this Console.ReadLine(); or Console.Read();

var someString = "(/n{})+++(/n{})---(/n{})$$$";_x000D_
var toRemove = "(/n{})"; // should find & remove last occurrence _x000D_
_x000D_
function removeLast(s, r){_x000D_
  s = s.split(r)_x000D_
  return s.slice(0,-1).join(r) + s.pop()_x000D_
}_x000D_
_x000D_
console.log(_x000D_
  removeLast(someString, toRemove)_x000D_
)

Breakdown:

s = s.split(toRemove)         // ["", "+++", "---", "$$$"]

s.slice(0,-1)                 //  ["", "+++", "---"]   

s.slice(0,-1).join(toRemove)  // "})()+++})()---"

s.pop()                       //  "$$$"   

the best way i found was to set the image you want to view responsively as a background image and sent a css property for the div as cover.

background-image : url('YOUR URL');
background-size : cover

I'm not sure whether "best practice for parsing XML" exists. There are numerous technologies suited for different situations. Which way to use depends on the concrete scenario.

You can go with LINQ to XML, XmlReader, XPathNavigator or even regular expressions. If you elaborate your needs, I can try to give some suggestions.

Concepts

Observables in short tackles asynchronous processing and events. Comparing to promises this could be described as observables = promises + events.

What is great with observables is that they are lazy, they can be canceled and you can apply some operators in them (like map, ...). This allows to handle asynchronous things in a very flexible way.

A great sample describing the best the power of observables is the way to connect a filter input to a corresponding filtered list. When the user enters characters, the list is refreshed. Observables handle corresponding AJAX requests and cancel previous in-progress requests if another one is triggered by new value in the input. Here is the corresponding code:

this.textValue.valueChanges
    .debounceTime(500)
    .switchMap(data => this.httpService.getListValues(data))
    .subscribe(data => console.log('new list values', data));

(textValue is the control associated with the filter input).

Here is a wider description of such use case: How to watch for form changes in Angular 2?.

There are two great presentations at AngularConnect 2015 and EggHead:

• Observables vs promises - https://egghead.io/lessons/rxjs-rxjs-observables-vs-promises

Christoph Burgdorf also wrote some great blog posts on the subject:

In action

In fact regarding your code, you mixed two approaches ;-) Here are they:

• Manage the observable by your own. In this case, you're responsible to call the subscribe method on the observable and assign the result into an attribute of the component. You can then use this attribute in the view for iterate over the collection:

  @Component({
    template: `
      <h1>My Friends</h1>
      <ul>
        <li *ngFor="#frnd of result">
          {{frnd.name}} is {{frnd.age}} years old.
        </li>
      </ul>
    `,
    directive:[CORE_DIRECTIVES]
  })
  export class FriendsList implement OnInit, OnDestroy {
    result:Array<Object>; 
  
    constructor(http: Http) {
    }
  
    ngOnInit() {
      this.friendsObservable = http.get('friends.json')
                    .map(response => response.json())
                    .subscribe(result => this.result = result);
     }
  
     ngOnDestroy() {
       this.friendsObservable.dispose();
     }
  }
  

  Returns from both get and map methods are the observable not the result (in the same way than with promises).

• Let manage the observable by the Angular template. You can also leverage the async pipe to implicitly manage the observable. In this case, there is no need to explicitly call the subscribe method.

  @Component({
    template: `
      <h1>My Friends</h1>
      <ul>
        <li *ngFor="#frnd of (result | async)">
          {{frnd.name}} is {{frnd.age}} years old.
        </li>
      </ul>
    `,
    directive:[CORE_DIRECTIVES]
  })
  export class FriendsList implement OnInit {
    result:Array<Object>; 
  
    constructor(http: Http) {
    }
  
    ngOnInit() {
      this.result = http.get('friends.json')
                    .map(response => response.json());
     }
  }
  

You can notice that observables are lazy. So the corresponding HTTP request will be only called once a listener with attached on it using the subscribe method.

You can also notice that the map method is used to extract the JSON content from the response and use it then in the observable processing.

Hope this helps you, Thierry

try td {background-color:white}

It just worked for a column I didn't want to get trampled by a previous column's long text.

As an alternative to WMios's answer, you can also use componentsSeparatedByCharactersInSet, which can be handy in the case you have more separators (blank space, comma, etc.).

With your specific input:

let separators = NSCharacterSet(charactersInString: " ")
var fullName: String = "First Last";
var words = fullName.componentsSeparatedByCharactersInSet(separators)

// words contains ["First", "Last"]

Using multiple separators:

let separators = NSCharacterSet(charactersInString: " ,")
var fullName: String = "Last, First Middle";
var words = fullName.componentsSeparatedByCharactersInSet(separators)

// words contains ["Last", "First", "Middle"]

const setTimeoutAsync = (cb, delay) =>
  new Promise((resolve) => {
    setTimeout(() => {
      resolve(cb());
    }, delay);
  });

We can pass custom 'cb fxn' like this one

I needed a quick way to determine if the user connection speed was fast enough to enable/disable some features in a site I’m working on, I made this little script that averages the time it takes to download a single (small) image a number of times, it's working pretty accurately in my tests, being able to clearly distinguish between 3G or Wi-Fi for example, maybe someone can make a more elegant version or even a jQuery plugin.

The call to InitializeComponent() (which is usually called in the default constructor of at least Window and UserControl) is actually a method call to the partial class of the control (rather than a call up the object hierarchy as I first expected).

This method locates a URI to the XAML for the Window/UserControl that is loading, and passes it to the System.Windows.Application.LoadComponent() static method. LoadComponent() loads the XAML file that is located at the passed in URI, and converts it to an instance of the object that is specified by the root element of the XAML file.

In more detail, LoadComponent creates an instance of the XamlParser, and builds a tree of the XAML. Each node is parsed by the XamlParser.ProcessXamlNode(). This gets passed to the BamlRecordWriter class. Some time after this I get a bit lost in how the BAML is converted to objects, but this may be enough to help you on the path to enlightenment.

Note: Interestingly, the InitializeComponent is a method on the System.Windows.Markup.IComponentConnector interface, of which Window/UserControl implement in the partial generated class.

Hope this helps!

409 Conflict could be an acceptable solution.

According to: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

The doc continues with an example:

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

In my case, I would like to PUT a string, that must be unique, to a database via an API. Before adding it to the database, I am checking that it is not already in the database.

If it is, I will return "Error: The string is already in the database", 409.

I believe this is what the OP wanted: an error code suitable for when the data does not pass the server's criteria.

You could achieve this quite easily with jQuery by registering for the click event of the anchors (with class="movie") and using the .load() method to send an AJAX request and replace the contents of the summary div:

$(function() {
    $('.movie').click(function() {
        $('#summary').load(this.href);

        // it's important to return false from the click
        // handler in order to cancel the default action
        // of the link which is to redirect to the url and
        // execute the AJAX request
        return false;
    });
});

You can also change the pop-up options themselves, to be more convenient for your normal use. Summary:

1. Run the SQL Management Studio Express 2008
2. Click the Tools -> Options

3. Select SQL Server Object Explorer . Now you should be able to see the options

   • Value for Edit Top Rows Command
   • Value for Select Top Rows Command

4. Give the Values 0 here to select/ Edit all the Records

Patrick's (accepted) answer is right: if not a: is the right way to do it. Harley Holcombe's answer is right that this is in the PEP 8 style guide. But what none of the answers explain is why it's a good idea to follow the idiom—even if you personally find it's not explicit enough or confusing to Ruby users or whatever.

Python code, and the Python community, has very strong idioms. Following those idioms makes your code easier to read for anyone experienced in Python. And when you violate those idioms, that's a strong signal.

It's true that if not a: doesn't distinguish empty lists from None, or numeric 0, or empty tuples, or empty user-created collection types, or empty user-created not-quite-collection types, or single-element NumPy array acting as scalars with falsey values, etc. And sometimes it's important to be explicit about that. And in that case, you know what you want to be explicit about, so you can test for exactly that. For example, if not a and a is not None: means "anything falsey except None", while if len(a) != 0: means "only empty sequences—and anything besides a sequence is an error here", and so on. Besides testing for exactly what you want to test, this also signals to the reader that this test is important.

But when you don't have anything to be explicit about, anything other than if not a: is misleading the reader. You're signaling something as important when it isn't. (You may also be making the code less flexible, or slower, or whatever, but that's all less important.) And if you habitually mislead the reader like this, then when you do need to make a distinction, it's going to pass unnoticed because you've been "crying wolf" all over your code.

First add the # -*- coding: utf-8 -*- line to the beginning of the file and then use u'foo' for all your non-ASCII unicode data:

def NewFunction():
    return u'£'

or use the magic available since Python 2.6 to make it automatic:

from __future__ import unicode_literals

Starting from Java 10:

List<E> oldList = List.of();
List<E> newList = List.copyOf(oldList);

List.copyOf() returns an unmodifiable List containing the elements of the given Collection.

The given Collection must not be null, and it must not contain any null elements.

Also, if you want to create a deep copy of a List, you can find many good answers here.

Use the cmd.exe command processor to build a timestamped file name to log your scheduled task's output

To build upon answers by others here, it may be that you want to create an output file that has the date and/or time embedded in the name of the file. You can use the cmd.exe command processor to do this for you.

Note: This technique takes the string output of internal Windows environment variables and slices them up based on character position. Because of this, the exact values supplied in the examples below may not be correct for the region of Windows you use. Also, with some regional settings, some components of the date or time may introduce a space into the constructed file name when their value is less than 10. To mitigate this issue, surround your file name with quotes so that any unintended spaces in the file name won't break the command-line you're constructing. Experiment and find what works best for your situation.

Be aware that PowerShell is more powerful than cmd.exe. One way it is more powerful is that it can deal with different Windows regions. But this answer is about solving this issue using cmd.exe, not PowerShell, so we continue.

Using cmd.exe

You can access different components of the date and time by slicing the internal environment variables %date% and %time%, as follows (again, the exact slicing values are dependent on the region configured in Windows):

• Year (4 digits): %date:~10,4%
• Month (2 digits): %date:~4,2%
• Day (2 digits): %date:~7,2%
• Hour (2 digits): %time:~0,2%
• Minute (2 digits): %time:~3,2%
• Second (2 digits): %time:~6,2%

Suppose you want your log file to be named using this date/time format: "Log_[yyyyMMdd]_[hhmmss].txt". You'd use the following:

Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt

To test this, run the following command line:

cmd.exe /c echo "Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt"

Putting it all together, to redirect both stdout and stderr from your script to a log file named with the current date and time, use might use the following as your command line:

cmd /c YourProgram.cmd > "Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt" 2>&1

Note the use of quotes around the file name to handle instances a date or time component may introduce a space character.

In my case, if the current date/time were 10/05/2017 9:05:34 AM, the above command-line would produce the following:

cmd /c YourProgram.cmd > "Log_20171005_ 90534.txt" 2>&1

To get left and right tabs (now also with sideways) support for Bootstrap 3, bootstrap-vertical-tabs component can be used.

https://github.com/dbtek/bootstrap-vertical-tabs

Add this line to autoload.php in the application folder:

$autoload['time_zone'] = date_default_timezone_set('Asia/Kolkata');

$("#registerSubmit").serialize() // returns all the data in your form
$.ajax({
     type: "POST",
     url: 'your url',
     data: $("#registerSubmit").serialize(),
     success: function() {
          //success message mybe...
     }
});

For me completely closing out of Xcode and then restarting the project worked.

This is not the solution for the original question, I don't believe, but it is one more simple thing to try before deleting files and folders, etc. Credit to this answer for the idea.

ps -o ppid=$(ps -ax | grep nameOfProcess | awk '{print $1}')

Prints out the changing process pid and then the parent PID. You can then kill the parent, or you can use that parentPID in the following command to get the name of the parent process:

ps -p parentPID -o comm=

For me the parent was 'login' :\

You need to provide a candidate for autowire. That means that an instance of PasswordHint must be known to spring in a way that it can guess that it must reference it.

Please provide the class head of PasswordHint and/or the spring bean definition of that class for further assistance.

Try changing the name of

PasswordHintAction action;

to

PasswordHintAction passwordHintAction;

so that it matches the bean definition.

So this is my first answer here, and because I needed something similar I did with pseudo elements for 2 inner shadows, and an extra DIV for an upper outer shadow. Don't know if this is the best solutions but maybe it will help someone.

HTML

<div class="shadow-block">
    <div class="shadow"></div>
    <div class="overlay">
        <div class="overlay-inner">
            content here
        </div>
    </div>
</div>

CSS

.overlay {
    background: #f7f7f4;
    height: 185px;
    overflow: hidden;
    position: relative;
    width: 100%; 
}

.overlay:before {
    border-radius: 50% 50% 50% 50%;
    box-shadow: 0 0 50px 2px rgba(1, 1, 1, 0.6);
    content: " ";
    display: block;
    margin: 0 auto;
    width: 80%;
}

.overlay:after {
    border-radius: 50% 50% 50% 50%;
    box-shadow: 0 0 70px 5px rgba(1, 1, 1, 0.5);
    content: "-";
    display: block;
    margin: 0 auto;
    position: absolute;
    bottom: -65px;
    left: -50%;
    right: -50%;
    width: 80%;
}

.shadow {
    position: relative;
    width:100%;
    height:8px;
    margin: 0 0 -22px 0;
    -webkit-box-shadow: 0px 0px 50px 3px rgba(1, 1, 1, 0.6);
    box-shadow: 0px 0px 50px 3px rgba(1, 1, 1, 0.6);
    border-radius: 50%;
}

I also faced the same problem, and get the columns name and its types. Then cast(col_Name as Char) from table name. From this way i get the problem as '0000-00-00 00:00:00' then I Update as valid date and time the error gets away for my case.

If you have one TableView for more tables, and one of this tables is grouped and the another one plain, than you can simulate the plain style with the function from UITableViewDelegate:

override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {   
    return CGFloat.min
}

This will tell you what line is the problem.

import csv

lines = []
with open('output.txt','r') as f:
    for line in f.readlines():
        lines.append(line[:-1])

with open('corrected.csv','w') as correct:
    writer = csv.writer(correct, dialect = 'excel')
    with open('input.csv', 'r') as mycsv:
        reader = csv.reader(mycsv)
        try:
            for i, row in enumerate(reader):
                if row[0] not in lines:
                   writer.writerow(row)
        except csv.Error:
            print('csv choked on line %s' % (i+1))
            raise

Perhaps this from daniweb would be helpful:

I'm getting this error when reading from a csv file: "Runtime Error! line contains NULL byte". Any idea about the root cause of this error?

...

Ok, I got it and thought I'd post the solution. Simply yet caused me grief... Used file was saved in a .xls format instead of a .csv Didn't catch this because the file name itself had the .csv extension while the type was still .xls

To be verbose it the removal of extension is demonstrated for workbooks.. which now have a variety of extensions . . a new unsaved Book1 has no ext . works the same for files

Function WorkbookIsOpen(FWNa$, Optional AnyExt As Boolean = False) As Boolean

Dim wWB As Workbook, WBNa$, PD%
FWNa = Trim(FWNa)
If FWNa <> "" Then
    For Each wWB In Workbooks
        WBNa = wWB.Name
        If AnyExt Then
            PD = InStr(WBNa, ".")
            If PD > 0 Then WBNa = Left(WBNa, PD - 1)
            PD = InStr(FWNa, ".")
            If PD > 0 Then FWNa = Left(FWNa, PD - 1)
            '
            ' the alternative of using split..  see commented out  below
            ' looks neater but takes a bit longer then the pair of instr and left
            ' VBA does about 800,000  of these small splits/sec
            ' and about 20,000,000  Instr Lefts per sec
            ' of course if not checking for other extensions they do not matter
            ' and to any reasonable program
            ' THIS DISCUSSIONOF TIME TAKEN DOES NOT MATTER
            ' IN doing about doing 2000 of this routine per sec

            ' WBNa = Split(WBNa, ".")(0)
            'FWNa = Split(FWNa, ".")(0)
        End If

        If WBNa = FWNa Then
            WorkbookIsOpen = True
            Exit Function
        End If
    Next wWB
End If

End Function

For the event where there are multiple check-boxes from which you'd like to select/deselect only a few, the following work with the Chrome Driver (somehow failed for IE Driver):

NOTE: My check-boxes didn't have an ID associated with them, which would be the best way to identify them according to the Documentation. Note the ! sign at the beginning of the statement.

if(!driver.findElement(By.xpath("//input[@type='checkbox' and @name='<name>']")).isSelected()) 
{
  driver.findElement(By.xpath("//input[@type='checkbox' and @name= '<name>']")).click();
}

If it comes to that, create a watchdog thread that messes up requests' internal state after 10 seconds, e.g.:

• closes the underlying socket, and ideally
• triggers an exception if requests retries the operation

Note that depending on the system libraries you may be unable to set deadline on DNS resolution.

There are two ways to go about this. You can either use the IDE to generate a WSDL, or you can do it via the command line.

1. To create it via the IDE:

In the solution explorer pane, right click on the project that you would like to add the Service to:

Then, you can enter the path to your service WSDL and hit go:

2. To create it via the command line:

Open a VS 2010 Command Prompt (Programs -> Visual Studio 2010 -> Visual Studio Tools)
Then execute:

WSDL /verbose C:\path\to\wsdl

WSDL.exe will then output a .cs file for your consumption.

If you have other dependencies that you received with the file, such as xsd's, add those to the argument list:

WSDL /verbose C:\path\to\wsdl C:\path\to\some\xsd C:\path\to\some\xsd

If you need VB output, use /language:VB in addition to the /verbose.

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

Note:The cause of the quotes is that when data moves from excel to clipboard it is fully complying with CSV standards which include quoting values that include tabs, new lines etc (and double-quote characters are replaced with two double-quote characters )

So another approach, especially as in OP's case when tabs/new lines are due to the formula, is to use alternate characters for tabs and hard returns. I use ascii Unit Separator =char(31) for tabs and ascii Record Separator =char(30) for new lines.

Then pasting into text editor will not involve the extra CSV rules and you can do a quick search and replace to convert them back again.

If the tabs/new lines are embedded in the data, you can do a search and replace in excel to convert them.

Whether using formula or changing the data, the key to choosing delimiters is never use characters that can be in the actual data. This is why I recommend the low level ascii characters.

Here is a very handy and helpful information about Git Push: Git Push: Just the Tip

The most common use of git push is to push your local changes to your public upstream repository. Assuming that the upstream is a remote named "origin" (the default remote name if your repository is a clone) and the branch to be updated to/from is named "master" (the default branch name), this is done with: git push origin master

git push origin will push changes from all local branches to matching branches the origin remote.

git push origin master will push changes from the local master branch to the remote master branch.

git push origin master:staging will push changes from the local master branch to the remote staging branch if it exists.

Try those methods, it should work:

• quit/exit Skype (make sure it's not running) because it reserves localhost:80
• disable Anti-virus (Try first to disable skype and running again, if it didn't work do this step)
• Right click on xampp control panel and run as administrator

for the GitLab Enterprise Edition 9.3.0

By default, master branch is protected so unprotect :)

1-Select you "project"

2-Select "Repository"

3-Select "branches"

4-Select "Project Settings"

5-In "Protected Branches" click to "expand"

6-and after click in "unprotect" button

Simple two line code solution using pandas

  import pandas as pd

  read_file = pd.read_csv ('File name.csv')
  read_file.to_excel ('File name.xlsx', index = None, header=True)

I know this is an old question. But I too needed the same one recently, and I got this question from stackoverflow + another answer from this blog. The answer which was in the blog was more straight forward as it focuses specially for this kind of a validation. Here is how to do it.

$.validator.addClassRules("price", {
     required: true,
     minlength: 2
});

This method does not require you to have validate method above this call.

Hope this will help someone in the future too. Source here.

I had the same problem, Here is my code before modification :

package com.asagaama

import org.apache.spark.SparkContext
import org.apache.spark.SparkConf
import org.apache.spark.rdd.RDD

/**
  * Created by asagaama on 16/02/2017.
  */
object Word {

  def countWords(sc: SparkContext) = {
    // Load our input data
    val input = sc.textFile("/Users/Documents/spark/testscase/test/test.txt")
    // Split it up into words
    val words = input.flatMap(line => line.split(" "))
    // Transform into pairs and count
    val counts = words.map(word => (word, 1)).reduceByKey { case (x, y) => x + y }
    // Save the word count back out to a text file, causing evaluation.
    counts.saveAsTextFile("/Users/Documents/spark/testscase/test/result.txt")
  }

  def main(args: Array[String]) = {
    val conf = new SparkConf().setAppName("wordCount")
    val sc = new SparkContext(conf)
    countWords(sc)
  }

}

And after replacing :

val conf = new SparkConf().setAppName("wordCount")

With :

val conf = new SparkConf().setAppName("wordCount").setMaster("local[*]")

It worked fine !

There is no version 1.3.0 for rope. 1.3.0 refers to the package cached-property. The highest available version of rope is 0.9.4.

You can install different versions with conda install package=version. But in this case there is only one version of rope so you don't need that.

The reason you see the cached-property in this listing is because it contains the string "rope": "cached-p rope erty"

py35_0 means that you need python version 3.5 for this specific version. If you only have python3.4 and the package is only for version 3.5 you cannot install it with conda.

I am not quite sure on the defaults either. It should be an indication that this package is inside the default conda channel.

PROBLEM SOLVED

I had exactly the same error. When the remote object got binded to the rmiregistry it was attached with the loopback IP Address which will obviously fail if you try to invoke a method from a remote address. In order to fix this we need to set the java.rmi.server.hostname property to the IP address where other devices can reach your rmiregistry over the network. It doesn't work when you try to set the parameter through the JVM. It worked for me just by adding the following line to my code just before binding the object to the rmiregistry:

System.setProperty("java.rmi.server.hostname","192.168.1.2");

In this case the IP address on the local network of the PC binding the remote object on the RMI Registry is 192.168.1.2.

Updating this post (2015) : unbind/bind should not be used anymore with jQuery 1.7+. Use instead the function off(). Example :

$('#id').off('click');
$('#id').click(function(){
    myNewFunction();
    //Other code etc.
});

Be sure that you call a non-parameter function in .click, otherwise it will be ignored.

It confusing to mock a "real" application configuration file. I suggest you roll your own because it is quite easy to parse an XML file using e.g. LINQ.

For example create an XML file MyDll.config like below and copy it alongside the DLL. To Keep it up to date set its property in Visual Studio to "Copy to Output Directory"

<?xml version="1.0" encoding="utf-8" ?>
 <configuration>
  <setting key="KeyboardEmulation" value="Off"></setting>
 </configuration>

In your Code read it like this:

    XDocument config = XDocument.Load("MyDll.config");
    var settings = config.Descendants("setting").Select(s => new { Key = s.Attribute("key").Value, Value = s.Attribute("value").Value });
    bool keyboardEmulation = settings.First(s => s.Key == "KeyboardEmulation").Value == "On";

typeof will serve the purpose I think

if(typeof foo != "undefined"){}

import csv

with open('file_name.csv', 'w') as csv_file:
    writer = csv.writer(csv_file)
    writer.writerow(('colum1', 'colum2', 'colum3'))
    for key, value in dictionary.items():
        writer.writerow([key, value[0], value[1]])

This would be the simplest way to write data to .csv file

If you are using the push_back there is no call for the string constructor. Otherwise it will create a string object via casting, then it will add the character in this string to the other string. Too much trouble for a tiny character ;)

You can check Date Mutators: https://laravel.com/docs/5.3/eloquent-mutators#date-mutators

You need set in your User model column from_date in $dates array and then you can change format in $dateFormat

The another option is also put this method to your User model:

public function getFromDateAttribute($value) {
    return \Carbon\Carbon::parse($value)->format('d-m-Y');
}

and then in view if you run {{ $user->from_date }} you will be see format that you want.

the best way it is create object with list of dynamic functions like:

const USER = 'user';

const userModule = {
  [USER + 'Action'] : function () { ... }, 
  [USER + 'OnClickHandler'] : function () { ... }, 
  [USER + 'OnCreateHook'] : function () { ... }, 
}

The server certificate is invalid, either because it is signed by an invalid CA (internal CA, self signed,...), doesn't match the server's name or because it is expired.

Either way, you need to find how to tell to the Python library that you are using that it must not stop at an invalid certificate if you really want to download files from this server.

num.toStringAsFixed() rounds. This one turns you num (n) into a string with the number of decimals you want (2), and then parses it back to your num in one sweet line of code:

n = num.parse(n.toStringAsFixed(2));

A chain of hooks is a set of functions in which each function calls the next. What is significant about a chain of hooks is that a programmer can add another function to the chain at run time. One way to do this is to look for a known location where the address of the first function in a chain is kept. You then save the value of that function pointer and overwrite the value at the initial address with the address of the function you wish to insert into the hook chain. The function then gets called, does its business and calls the next function in the chain (unless you decide otherwise). Naturally, there are a number of other ways to create a chain of hooks, from writing directly to memory to using the metaprogramming facilities of languages like Ruby or Python.

An example of a chain of hooks is the way that an MS Windows application processes messages. Each function in the processing chain either processes a message or sends it to the next function in the chain.

I don't know if this will help, but I did this:

LocationManager locationManager  = (LocationManager) context.getSystemService(context.LOCATION_SERVICE);

If you're already on EL 3.0 (Java EE 7; WildFly, Tomcat 8, GlassFish 4, etc), then you could use the new += operator for this:

<c:out value="${empty value ? 'none' : value += ' enabled'}" />

If you're however not on EL 3.0 yet, and the value is a genuine java.lang.String instance (and thus not e.g. java.lang.Long), then use EL 2.2 (Java EE 7; JBoss AS 6/7, Tomcat 7, GlassFish 3, etc) capability of invoking direct methods with arguments, which you then apply on String#concat():

<c:out value="${empty value ? 'none' : value.concat(' enabled')}" />

Or if you're even not on EL 2.2 yet, then use JSTL <c:set> to create a new EL variable with the concatenated values just inlined in value:

<c:set var="enabled" value="${value} enabled" />
<c:out value="${empty value ? 'none' : enabled}" />

Motion is an alternative to Zoneminder. It has a steeper setup curve as everything is configured via config files.However, the config files are nicely commented and it's easier than it sounds. It's very reliable once running as well.

To add a Foscam camera (mentioned above) use the following syntax to stream the video from the camera.

netcam_url http://<IPADDRESS>/videostream.cgi?user=admin?pwd=

Where the user is admin with a blank password (the default for Foscam cameras).

For really high uptime/reliablity consider using a monitoring tool such as Monit. This works well with Motion.

You can also use interface builder if you don't want to make the adjustments in code. Here I left align the text and also indent it some:

Don't forget you can also align an image in the button too.:

@media only screen 
and (min-device-width : 320px) 
and (max-device-width : 480px) { #title_message { display: none; }}

This would be for a responsive design with a single page for an iphone screen specifically. Are you actually routing to a different mobile page?

An optional way if you want to use pure Python:

ElementTree is good for most cases, but it can't CData and pretty print.

So, if you need CData and pretty print you should use minidom:

minidom_example.py:

from xml.dom import minidom

doc = minidom.Document()

root = doc.createElement('root')
doc.appendChild(root)

leaf = doc.createElement('leaf')
text = doc.createTextNode('Text element with attributes')
leaf.appendChild(text)
leaf.setAttribute('color', 'white')
root.appendChild(leaf)

leaf_cdata = doc.createElement('leaf_cdata')
cdata = doc.createCDATASection('<em>CData</em> can contain <strong>HTML tags</strong> without encoding')
leaf_cdata.appendChild(cdata)
root.appendChild(leaf_cdata)

branch = doc.createElement('branch')
branch.appendChild(leaf.cloneNode(True))
root.appendChild(branch)

mixed = doc.createElement('mixed')
mixed_leaf = leaf.cloneNode(True)
mixed_leaf.setAttribute('color', 'black')
mixed_leaf.setAttribute('state', 'modified')
mixed.appendChild(mixed_leaf)
mixed_text = doc.createTextNode('Do not use mixed elements if it possible.')
mixed.appendChild(mixed_text)
root.appendChild(mixed)

xml_str = doc.toprettyxml(indent="  ")
with open("minidom_example.xml", "w") as f:
    f.write(xml_str)

minidom_example.xml:

<?xml version="1.0" ?>
<root>
  <leaf color="white">Text element with attributes</leaf>
  <leaf_cdata>
<![CDATA[<em>CData</em> can contain <strong>HTML tags</strong> without encoding]]>  </leaf_cdata>
  <branch>
    <leaf color="white">Text element with attributes</leaf>
  </branch>
  <mixed>
    <leaf color="black" state="modified">Text element with attributes</leaf>
    Do not use mixed elements if it possible.
  </mixed>
</root>

let's suppose the new and untracked file is called: "views.json". if you want to change branch by stashing the state of your app, I generally type:

git add views.json

Then:

git stash

And it would be stashed. Then I can just change branch with

git checkout other-nice-branch

From Using Triggers:

Detecting the DML Operation That Fired a Trigger

If more than one type of DML operation can fire a trigger (for example, ON INSERT OR DELETE OR UPDATE OF Emp_tab), the trigger body can use the conditional predicates INSERTING, DELETING, and UPDATING to check which type of statement fire the trigger.

So

IF DELETING THEN ... END IF;

should work for your case.

In your case you can use __FILE__ variable !
It should help.
It is one of predefined.
Read more about predefined constants in PHP http://php.net/manual/en/language.constants.predefined.php

If the list you use for the spinner is an object then you can find its position like this

private int selectSpinnerValue( List<Object> ListSpinner,String myString) 
{
    int index = 0;
    for(int i = 0; i < ListSpinner.size(); i++){
      if(ListSpinner.get(i).getValueEquals().equals(myString)){
          index=i;
          break;
      }
    }
    return index;
}

using:

 int index=selectSpinnerValue(ListOfSpinner,StringEquals);
    spinner.setSelection(index,true);

Simple method to get resource ID:

public int getDrawableName(Context ctx,String str){
    return ctx.getResources().getIdentifier(str,"drawable",ctx.getPackageName());
}

Regardless of the API level, Check String arrays and Object arrays in SharedPreferences

SAVE ARRAY

public boolean saveArray(String[] array, String arrayName, Context mContext) {   
    SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);  
    SharedPreferences.Editor editor = prefs.edit();  
    editor.putInt(arrayName +"_size", array.length);  
    for(int i=0;i<array.length;i++)  
        editor.putString(arrayName + "_" + i, array[i]);  
    return editor.commit();  
} 

LOAD ARRAY

public String[] loadArray(String arrayName, Context mContext) {  
    SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);  
    int size = prefs.getInt(arrayName + "_size", 0);  
    String array[] = new String[size];  
    for(int i=0;i<size;i++)  
        array[i] = prefs.getString(arrayName + "_" + i, null);  
    return array;  
}  

for (int i = 0; i < 6; i++)
{
    test.ColumnDefinitions.Add(new ColumnDefinition());

    Label t1 = new Label();
    t1.Content = "Test" + i;

    Grid.SetColumn(t1, i);
    Grid.SetRow(t1, 0);
    test.Children.Add(t1);
}

I had the same problem. I stash my changes with git stash and hard reset the branch in local to a previous commit(I thought it caused that) then did a git pull and I am not getting that head detached now. Dont forget git stash apply to have your changes again.

Go into your AndroidManifest.xml file

• Click on the Application Tab
• Find the Text Box Labelled "Icon"
• Then click the "Browse" button at the end of the text box
• Click the Button Labelled: "Create New Icon..."
  
  
• Create your icon
• Click Finish
  
• Click "Yes to All" if you already have the icon set to something else.

Enjoy using a gui rather then messing with an image editor! Hope this helps!

Or in php >= 7.3.0

you can use the function array_key_last()

As described in php.net — Gets the last key of an array

https://www.php.net/manual/en/function.array-key-last.php

From the documentation:

Due to limitations in JavaScript, Vue cannot detect the following changes to an array:

1. When you directly set an item with the index, e.g. vm.items[indexOfItem] = newValue
2. When you modify the length of the array, e.g. vm.items.length = newLength

In my case i stumbled on this problem when migrating from Angular to VUE. Fix was quite easy, but really difficult to find:

setValue(index) {
    Vue.set(this.arr, index, !this.arr[index]);
    this.$forceUpdate(); // Needed to force view rerendering
}

A CASE statement is an expression, just like a boolean comparison. That means the 'AND' needs to go before the 'CASE' statement, not within it.:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)

AND -- Added the "AND" here

CASE WHEN @day = 'Monday' THEN (Monday = 1)   -- Removed "AND" 
    WHEN @day = 'Tuesday' THEN (Tuesday = 1)  -- Removed "AND" 
    ELSE AND (Wednesday = 1) 
END

Google Apps Script is javascript, you can use all the string methods...

var grade = itemResponse.getResponse();
if(grade.indexOf("9th")>-1){do something }

You can find doc on many sites, this one for example.

git checkout origin/[branch] .
git status

// Note dot (.) at the end. And all will be good

If you just need to read the data.

encrypt(str.data(),str.size());

If you need a read/write copy of the data put it into a vector. (Don;t dynamically allocate space that's the job of vector).

std::vector<byte>  source(str.begin(),str.end());
encrypt(&source[0],source.size());

Of course we are all assuming that byte is a char!!!

One option would be to add your working directory to your Chrome "workspace" which allows Chrome to map local files to those on the page. It will then detect changes in the local files, and update the page in real-time.

This can be done from the "Sources" tab of Devtools:

Click on the "Filesystem" tab in the file browser sidebar, then click the +Plus sign button to "Add folder to workspace" - you will be prompted with a banner at the top of the screen to allow or deny local file access:

Once allowed, the folder will appear in the "Filesystem" tab on the left. Chrome will now attempt to associate each file in the filesystem tab with a file in the page. Sometimes you will need to reload the page once for this to function correctly.

Once this is done, Chrome should have no trouble picking up local changes, in fact you won't even need to reload to get the changes in many cases, and you can make edits to the local files directly from Devtools (which is extremely useful for CSS, it even comments out CSS lines when you toggle the checkboxes in the Styles tab).

More information on Workspaces in Chrome.

You don't need any webpack configuration for this..

In your component just give image path. By default react will know its in public directory.

<img src="/image.jpg" alt="image" />

// display error messages for a page, but never more than 3 errors
window.onerror = function(msg, url, line) {
if (onerror.num++ < onerror.max) {
alert("ERROR: " + msg + "\n" + url + ":" + line);
return true;
}
}
onerror.max = 3;
onerror.num = 0;

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter

I'm guessing the original poster is coming from a C++/STL background which is causing some confusion. In C++ std::list is a doubly linked list.

In Java [java.util.]List is an implementation-free interface (pure abstract class in C++ terms). List can be a doubly linked list - java.util.LinkedList is provided. However, 99 times out of 100 when you want a make a new List, you want to use java.util.ArrayList instead, which is the rough equivalent of C++ std::vector. There are other standard implementations, such as those returned by java.util.Collections.emptyList() and java.util.Arrays.asList().

From a performance standpoint there is a very small hit from having to go through an interface and an extra object, however runtime inlining means this rarely has any significance. Also remember that String are typically an object plus array. So for each entry, you probably have two other objects. In C++ std::vector<std::string>, although copying by value without a pointer as such, the character arrays will form an object for string (and these will not usually be shared).

If this particular code is really performance-sensitive, you could create a single char[] array (or even byte[]) for all the characters of all the strings, and then an array of offsets. IIRC, this is how javac is implemented.

Can't you use the first selector ?

something like: tr:first

Use a linked list. It was designed for this exact situation.
If you still need the dictionary O(1) lookups, use both a dictionary and a linked list.

The volatile keyword is used:

• to make non atomic 64-bit operations atomic: long and double. (all other, primitive accesses are already guaranteed to be atomic!)
• to make variable updates guaranteed to be seen by other threads + visibility effects: after writing to a volatile variable, all the variables that where visible before writing that variable become visible to another thread after reading the same volatile variable (happen-before ordering).

The java.util.concurrent.atomic.* classes are, according to the java docs:

A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form:

boolean compareAndSet(expectedValue, updateValue);

The atomic classes are built around the atomic compareAndSet(...) function that maps to an atomic CPU instruction. The atomic classes introduce the happen-before ordering as the volatile variables do. (with one exception: weakCompareAndSet(...)).

From the java docs:

When a thread sees an update to an atomic variable caused by a weakCompareAndSet, it does not necessarily see updates to any other variables that occurred before the weakCompareAndSet.

To your question:

Does this mean that whosoever takes lock on it, that will be setting its value first. And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

You don't lock anything, what you are describing is a typical race condition that will happen eventually if threads access shared data without proper synchronization. As already mentioned declaring a variable volatile in this case will only ensure that other threads will see the change of the variable (the value will not be cached in a register of some cache that is only seen by one thread).

What is the difference between AtomicInteger and volatile int?

AtomicInteger provides atomic operations on an int with proper synchronization (eg. incrementAndGet(), getAndAdd(...), ...), volatile int will just ensure the visibility of the int to other threads.

Yes, in your formula, you can cbind the numeric variables to be aggregated:

aggregate(cbind(x1, x2) ~ year + month, data = df1, sum, na.rm = TRUE)
   year month         x1          x2
1  2000     1   7.862002   -7.469298
2  2001     1 276.758209  474.384252
3  2000     2  13.122369 -128.122613
...
23 2000    12  63.436507  449.794454
24 2001    12 999.472226  922.726589

See ?aggregate, the formula argument and the examples.

$query_ids = $this->getEntityManager()

        GROUP BY e_.id")
     ->setMaxResults(5)
     ->setMaxResults($limit)

HERE in the second query the result of the first query should be passed ..

$query_select = "SELECT e
      FROM MuzichCoreBundle:Element e 
      WHERE e.id IN (".$query_ids->getResult().")

For Xcode 9.1 and Swift 4:

1. Import StoreKit:

import StoreKit

2.Conform the protocol

SKStoreProductViewControllerDelegate

3.Implement the protocol

func openStoreProductWithiTunesItemIdentifier(identifier: String) {
    let storeViewController = SKStoreProductViewController()
    storeViewController.delegate = self

    let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier]
    storeViewController.loadProduct(withParameters: parameters) { [weak self] (loaded, error) -> Void in

        if loaded {
            // Parent class of self is UIViewContorller
            self?.present(storeViewController, animated: true, completion: nil)
        }
    }   
}

3.1

func productViewControllerDidFinish(_ viewController: SKStoreProductViewController) {
    viewController.dismiss(animated: true, completion: nil)
}

4. How to use:

openStoreProductWithiTunesItemIdentifier(identifier: "here_put_your_App_id")

Note:

It is very important to enter the exact ID of your APP. Because this cause error (not show the error log, but nothing works fine because of this)

php curl lib is just a wrapper of cUrl, so, first of all, you should install cUrl. Download the cUrl source to your linux server. Then, use the follow commands to install:

tar zxvf cUrl_src_taz
cd cUrl_src_taz
./configure --prefix=/curl/install/home
make
make test    (optional)
make install
ln -s  /curl/install/home/bin/curl-config /usr/bin/curl-config

Then, copy the head files in the "/curl/install/home/include/" to "/usr/local/include". After all above steps done, the php curl extension configuration could find the original curl, and you can use the standard php extension method to install php curl.
Hope it helps you, :)

Since Go 1.11+, GOPATH is no longer recommended, the new way is using Go Modules.

Say you're writing a program called simple:

1. Create a directory:

   mkdir simple
   cd simple
   

2. Create a new module:

   go mod init github.com/username/simple
   # Here, the module name is: github.com/username/simple.
   # You're free to choose any module name.
   # It doesn't matter as long as it's unique.
   # It's better to be a URL: so it can be go-gettable.
   

3. Put all your files in that directory.

4. Finally, run:

   go run .
   

5. Alternatively, you can create an executable program by building it:

   go build .
   
   # then:
   ./simple     # if you're on xnix
   
   # or, just:
   simple       # if you're on Windows
   

For more information, you may read this.

Go has included support for versioned modules as proposed here since 1.11. The initial prototype vgo was announced in February 2018. In July 2018, versioned modules landed in the main Go repository. In Go 1.14, module support is considered ready for production use, and all users are encouraged to migrate to modules from other dependency management systems.

Old question, but have you checked out JFormDesigner?

You can indeed match all those characters, but it's safer to escape the - so that it is clear that it be taken literally.

If you are using a POSIX variant you can opt to use:

([[:alnum:]\-_]+)

But a since you are including the underscore I would simply use:

([\w\-]+)

(works in all variants)

The following seems to work as well, and it's a little bit shorter than the other answers:

T result = (T)Convert.ChangeType(otherTypeObject, typeof(T));

try this out

$("div[id^='car']:last").after($('#car2').clone());

I know its Too late But I hope it will work new comers Try This Its Working ... :D

With the help of dr answer, I wrote a workaround that makes the conversion to put in your .bashrc. It won't break anything if you don't have any timestamp or already correct timestamps.

dmesg_with_human_timestamps () {
    $(type -P dmesg) "$@" | perl -w -e 'use strict;
        my ($uptime) = do { local @ARGV="/proc/uptime";<>}; ($uptime) = ($uptime =~ /^(\d+)\./);
        foreach my $line (<>) {
            printf( ($line=~/^\[\s*(\d+)\.\d+\](.+)/) ? ( "[%s]%s\n", scalar localtime(time - $uptime + $1), $2 ) : $line )
        }'
}
alias dmesg=dmesg_with_human_timestamps

Also, a good reading on the dmesg timestamp conversion logic & how to enable timestamps when there are none: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92677
