for those of us that love all things pandas, apply, and of course lambda functions:

df['Col3'] = df[['Col1', 'Col2']].apply(lambda x: ''.join(x), axis=1)

Some answers uses each, but map is a better alternative here IMHO:

$("select#example option").map(function() {return $(this).val();}).get();

There are (at least) two map functions in jQuery. Thomas Petersen's answer uses "Utilities/jQuery.map"; this answer uses "Traversing/map" (and therefore a little cleaner code).

It depends on what you are going to do with the values. If you, let's say, want to return the values from a function, map is probably the better alternative. But if you are going to use the values directly you probably want each.

Here is how to make one:

The repository is not down, it looks like they've changed how they host files (I guess they have restored some old code):

Now you have to add the /package-name/ before the -

Eg:

http://registry.npmjs.org/-/npm-1.1.48.tgz
http://registry.npmjs.org/npm/-/npm-1.1.48.tgz

There are 3 ways to solve it:

• Use a complete mirror:

• Use a public proxy:

  --registry http://165.225.128.50:8000

• Host a local proxy:

  https://github.com/hughsk/npm-quickfix

git clone https://github.com/hughsk/npm-quickfix.git
cd npm-quickfix
npm set registry http://localhost:8080/
node index.js

I'd personally go with number 3 and revert to npm set registry http://registry.npmjs.org/ as soon as this get resolved.

JAXB is an ideal solution. But you do not necessarily need xsd and xjc for that. More often than not you don't have an xsd but you know what your xml is. Simply analyze your xml, e.g.,

<customer id="100">
    <age>29</age>
    <name>mkyong</name>
</customer>

Create necessary model class(es):

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

    @XmlElement
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    @XmlElement
    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

Try to unmarshal:

JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(new File("C:\\file.xml"));

A vector is a container class while an array is an allocated memory.

Add this line to your edittext

android:inputType="text"

Your PHP array is defined as:

$arr = array ('resonse'=>'error','comment'=>'test comment here');

Notice the mispelling "resonse". Also, as RaYell has mentioned, you have to use data instead of json in your success function because its parameter is currently data.

Try editing your PHP file to change the spelling form resonse to response. It should work then.

So.. I was also looking into this matter and saw that most of the answers here are asking to fade the container element, not the actual background-image. Then a hack crossed my mind. We can give multiple background right? what if we overlay other color and make it transparent, like code below-

 background: url("//unsplash.it/500/400") rgb(255, 255, 255, 0.5) no-repeat center;

This code actually works stand alone. Try it. We gave a bg image and asked other white color with transparency on top of the image and Voila. TIP- we can give different colors and transparencies to get different filter kind of effect.

Had a similar need. $compile does the job. (Not completely sure if this is "THE" way to do it, still working my way through angular)

http://jsbin.com/ebuhuv/7/edit - my exploration test.

One thing to note (per my example), one of my requirements was that the template would change based on a type attribute once you clicked save, and the templates were very different. So though, you get the data binding, if need a new template in there, you will have to recompile.

No, you can't.

There's no reason why you would need to. This is a one-time operation and so takes only an additional second or two to actually type and execute.

If you're adding columns in your web application this is more indicative of a flaw in your data-model as you shouldn't need to be doing it.

In response to your comment that a comment is a column attribute; it may seem so but behind the scenes Oracle stores this as an attribute of an object.

SQL> desc sys.com$
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 OBJ#                                      NOT NULL NUMBER
 COL#                                               NUMBER
 COMMENT$                                           VARCHAR2(4000)

SQL>

The column is optional and sys.col$ does not contain comment information.

I assume, I have no knowledge, that this was done in order to only have one system of dealing with comments rather than multiple.

You need to open TCP port 8787 in the ec2 Security Group. Also need to open the same port on the EC2 instance's firewall.

Something is wrong with that string try like this:

Worksheets(data_sheet).Range("C2").Value = ProcessString(CStr(last_name))

In the function viewDidLoad of the UIViewController use the code:

self.navigationItem.hidesBackButton = YES;

Instead of doing all these things just

Another way of doing it:

DateTime today = DateTime.Today;
DateTime endOfMonth = new DateTime(today.Year, 
                                   today.Month, 
                                   DateTime.DaysInMonth(today.Year, 
                                                        today.Month));

Er, it's not really a test if you don't add something to your path:

bill@bill-desktop:~$ ls -l /opt/pkg/bin
total 12
-rwxr-xr-x 1 root root   28 2009-01-22 18:58 foo
bill@bill-desktop:~$ which foo

$string = <p>Awesome</p><b> Website</b><i> by Narayan</i>. Thanks for visiting enter code here;
$tags = array("p", "i");

echo preg_replace('#<(' . implode( '|', $tags) . ')(?:[^>]+)?>.*?</\1>#s', '', $string);

When you subtract two dates in Oracle, you get the number of days between the two values. So you just have to multiply to get the result in minutes instead:

SELECT (date2 - date1) * 24 * 60 AS minutesBetween
FROM ...

Added a few optional parameters for creating "future safe" sequences.

CREATE SEQUENCE <NAME>
  START WITH 1
  INCREMENT BY 1

Add the below dependency to your pom.xml:

I would change the query in the following ways:

1. Do the aggregation in subqueries. This can take advantage of more information about the table for optimizing the group by.
2. Combine the second and third subqueries. They are aggregating on the same column. This requires using a left outer join to ensure that all data is available.
3. By using count(<fieldname>) you can eliminate the comparisons to is null. This is important for the second and third calculated values.
4. To combine the second and third queries, it needs to count an id from the mde table. These use mde.mdeid.

The following version follows your example by using union all:

SELECT CAST(Detail.ReceiptDate AS DATE) AS "Date",
       SUM(TOTALMAILED) as TotalMailed,
       SUM(TOTALUNDELINOTICESRECEIVED) as TOTALUNDELINOTICESRECEIVED,
       SUM(TRACEUNDELNOTICESRECEIVED) as TRACEUNDELNOTICESRECEIVED
FROM ((select SentDate AS "ReceiptDate", COUNT(*) as TotalMailed,
              NULL as TOTALUNDELINOTICESRECEIVED, NULL as TRACEUNDELNOTICESRECEIVED
       from MailDataExtract
       where SentDate is not null
       group by SentDate
      ) union all
      (select MDE.ReturnMailDate AS ReceiptDate, 0,
              COUNT(distinct mde.mdeid) as TOTALUNDELINOTICESRECEIVED,
              SUM(case when sd.ReturnMailTypeId = 1 then 1 else 0 end) as TRACEUNDELNOTICESRECEIVED
       from MailDataExtract MDE left outer join
            DTSharedData.dbo.ScanData SD
            ON SD.ScanDataID = MDE.ReturnScanDataID
       group by MDE.ReturnMailDate;
      )
     ) detail
GROUP BY CAST(Detail.ReceiptDate AS DATE)
ORDER BY 1;

The following does something similar using full outer join:

SELECT coalesce(sd.ReceiptDate, mde.ReceiptDate) AS "Date",
       sd.TotalMailed, mde.TOTALUNDELINOTICESRECEIVED,
       mde.TRACEUNDELNOTICESRECEIVED
FROM (select cast(SentDate as date) AS "ReceiptDate", COUNT(*) as TotalMailed
      from MailDataExtract
      where SentDate is not null
      group by cast(SentDate as date)
     ) sd full outer join
    (select cast(MDE.ReturnMailDate as date) AS ReceiptDate,
            COUNT(distinct mde.mdeID) as TOTALUNDELINOTICESRECEIVED,
            SUM(case when sd.ReturnMailTypeId = 1 then 1 else 0 end) as TRACEUNDELNOTICESRECEIVED
     from MailDataExtract MDE left outer join
          DTSharedData.dbo.ScanData SD
          ON SD.ScanDataID = MDE.ReturnScanDataID
     group by cast(MDE.ReturnMailDate as date)
    ) mde
    on sd.ReceiptDate = mde.ReceiptDate
ORDER BY 1;

When using INTEGER columns (that can be NULL) in MySQL, PDO has some (to me) unexpected behaviour.

If you use $stmt->execute(Array), you have to specify the literal NULL and cannot give NULL by variable reference. So this won't work:

// $val is sometimes null, but sometimes an integer
$stmt->execute(array(
    ':param' => $val
));
// will cause the error 'incorrect integer value' when $val == null

But this will work:

// $val again is sometimes null, but sometimes an integer
$stmt->execute(array(
    ':param' => isset($val) ? $val : null
));
// no errors, inserts NULL when $val == null, inserts the integer otherwise

Tried this on MySQL 5.5.15 with PHP 5.4.1

For big CLOB selects also can be used:

SELECT dbms_lob.substr( column_name, dbms_lob.getlength(column_name), 1) FROM foo

I definitely agree that this is perfect for an extension method, but I think it can be improved a bit.

public static string Remove(this string source, string remove,  int firstN)
    {
        if(firstN <= 0 || string.IsNullOrEmpty(source) || string.IsNullOrEmpty(remove))
        {
            return source;
        }
        int index = source.IndexOf(remove);
        return index < 0 ? source : source.Remove(index, remove.Length).Remove(remove, --firstN);
    }

This does a bit of recursion which is always fun.

Here is a simple unit test as well:

   [TestMethod()]
    public void RemoveTwiceTest()
    {
        string source = "look up look up look it up";
        string remove = "look";
        int firstN = 2;
        string expected = " up  up look it up";
        string actual;
        actual = source.Remove(remove, firstN);
        Assert.AreEqual(expected, actual);

    }

From MSDN:

The foreach statement repeats a group of embedded statements for each element in an array or an object collection that implements the System.Collections.IEnumerable or System.Collections.Generic.IEnumerable(Of T) interface.

So, it's not necessarily Array. It could even be a lazy collection with no idea about the count of items in the collection.

Use the first example. If the key doesn't exist it will be added.

var a = new Array();
a['name'] = 'oscar';
alert(a['name']);

Will pop up a message box containing 'oscar'.

Try:

var text = 'name = oscar'
var dict = new Array()
var keyValuePair = text.replace(/ /g,'').split('=');
dict[ keyValuePair[0] ] = keyValuePair[1];
alert( dict[keyValuePair[0]] );

Android Studio now comes bundled with OpenJDK 8 . Legacy projects can still use JDK7 or JDK8

Reference: https://developer.android.com/studio/releases/index.html

TEXT and CHAR will convert to/from the character set they have associated with time. BLOB and BINARY simply store bytes.

BLOB is used for storing binary data while Text is used to store large string.

BLOB values are treated as binary strings (byte strings). They have no character set, and sorting and comparison are based on the numeric values of the bytes in column values.

TEXT values are treated as nonbinary strings (character strings). They have a character set, and values are sorted and compared based on the collation of the character set.

You can set a reference to the Scripting.Runtime library and then use the FileSystemObject. It has a DeleteFile method and a FileExists method.

See the MSDN article here.

I'm going to assume your host is using C-Panel - and that it's probably HostGator or GoDaddy. In both cases they use C-Panel (in fact, a lot of hosts do) to make the Server administration as easy as possible on you, the end user. Even if you are hosting through someone else - see if you can log in to some kind of admin panel and find an .htaccess file that you can edit. (Note: The period before just means that it's a "hidden" file/directory).

Once you find the htaccess file add the following line:

1. Header set Access-Control-Allow-Origin "*" Just to see if it works. Warning: Do not use this line on a production server

It should work. If not, call your host and ask them why the line isn't working - they'll probably be able to help you quickly from there.

2. Once you do have the above working change the * to the address of the requesting domain http://cyclistinsuranceaustralia.com.au/. You may find an issue with canonical addressing (including the www) and if so you may need to configure your host for a redirect. That's a different and smaller bridge to cross though. You'll at least be in the right place.

packages installed using pip can be uninstalled completely using

pip uninstall <package>

refrence link

pip uninstall is likely to fail if the package is installed using python setup.py install as they do not leave behind metadata to determine what files were installed.

packages still show up in pip list if their paths(.pth file) still exist in your site-packages or dist-packages folder. You'll need to remove them as well in case you're removing using rm -rf

This is the solution that I came up with for this problem which works for me.

library used: momentjs with plain javascript Date class.

Step 1. Convert String date to moment object (PS: moment retains the original date and time as long as toDate() method is not called):

const dateMoment = moment("2005-07-08T11:22:33+0000");

Step 2. Extract hours and minutes values from the previously created moment object:

  const hours = dateMoment.hours();
  const mins = dateMoment.minutes();

Step 3. Convert moment to Date(PS: this will change the original date based on the timezone of your browser/machine, but don't worry and read step 4.):

  const dateObj = dateMoment.toDate();

Step 4. Manually set the hours and minutes extracted in Step 2.

  dateObj.setHours(hours);
  dateObj.setMinutes(mins);

Step 5. dateObj will now have show the original Date without any timezone difference. Even the Daylight time changes won't have any effect on the date object as we are manually setting the original hours and minutes.

Hope this helps.

Try

set expandtab

for soft tabs.

To fix pre-existing tabs:

:%s/\t/  /g

I used two spaces since you already set your tabstop to 2 spaces.

You can write your select query as,

select * from table_name where to_char(date_time_column, 'YYYY-MM')  = '2011-03';

can use this,

lemons ? alert("please give me a lemonade") : alert("then give me a beer");

explanation: if lemons is true then alert("please give me a lemonade"), if not, alert("then give me a beer")

Depending on where you are in the kestrel pipeline - if you have access to IConfiguration (Startup.cs constructor) or IWebHostEnvironment (formerly IHostingEnvironment) you can either inject the IWebHostEnvironment into your constructor or just request the key from the configuration.

Inject IWebHostEnvironment in Startup.cs Constructor

public Startup(IConfiguration configuration, IWebHostEnvironment env)
{
     var contentRoot = env.ContentRootPath;
}

Using IConfiguration in Startup.cs Constructor

public Startup(IConfiguration configuration)
{
     var contentRoot = configuration.GetValue<string>(WebHostDefaults.ContentRootKey);
}

I had this same problem for days. Keeping srand() out of the loop is a +. Also, dont assign rand() % 100 to any variable. Simply cout rand() % 100 in the loop. Try this:

    srand (time(NULL));
    (int t=0;t<10;t++)
    {
    cout << rand() % 100 << endl;
    } 

An edge case: Above every answer is almost correct but I was stuck in an edge case. If any user randomly clicks the button multiple times within a few seconds then after playing some sound it doesn't respond anymore.

Reason: Initialize Mediaplayer object is very expensive. It also deals with resources (audio file) so it takes some time for it. When users randomly initialize and calling a method of MediaPlayer's methods like start(), stop(), release(), etc can cause IllegalStateException which I faced.

Solution: Thanks caw for his suggestion in the comment about Android-Audio. It has just a simple two java classes (MusicManager.java, SoundManager.java).

You can use MusicManager.java if you want to play one-off sound files -

MusicManager.getInstance().play(MyActivity.this, R.raw.my_sound);

You can use SoundManager.java if you want to play multiple sounds frequently and fast -

class MyActivity extends Activity {

    private SoundManager mSoundManager;

    @Override
    protected void onResume() {
        super.onResume();

        int maxSimultaneousStreams = 3;
        mSoundManager = new SoundManager(this, maxSimultaneousStreams);
        mSoundManager.start();
        mSoundManager.load(R.raw.my_sound_1);
        mSoundManager.load(R.raw.my_sound_2);
        mSoundManager.load(R.raw.my_sound_3);
    }

    private void playSomeSound() {
        if (mSoundManager != null) {
            mSoundManager.play(R.raw.my_sound_2);
        }
    }

    @Override
    protected void onPause() {
        super.onPause();

        if (mSoundManager != null) {
            mSoundManager.cancel();
            mSoundManager = null;
        }
    }

}

Try confirm the data type (SqlDbType) for each parameter in the database and do it this way;

 using(SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["connSpionshopString"].ConnectionString))
 {
            connection.Open();
            string sql =  "INSERT INTO klant(klant_id,naam,voornaam) VALUES(@param1,@param2,@param3)";
            using(SqlCommand cmd = new SqlCommand(sql,connection)) 
            {
                  cmd.Parameters.Add("@param1", SqlDbType.Int).value = klantId;  
                  cmd.Parameters.Add("@param2", SqlDbType.Varchar, 50).value = klantNaam;
                  cmd.Parameters.Add("@param3", SqlDbType.Varchar, 50).value = klantVoornaam;
                  cmd.CommandType = CommandType.Text;
                  cmd.ExecuteNonQuery(); 
            }
 }

private void processLine(String[] strings) {
    Integer[] intarray=new Integer[strings.length];
    for(int i=0;i<strings.length;i++) {
        intarray[i]=Integer.parseInt(strings[i]);
    }
    for(Integer temp:intarray) {
        System.out.println("convert int array from String"+temp);
    }
}

You might be needed to restart the process if app.get not working. Press ctl+c and then restart node app.

One pitfall with alloca is that longjmp rewinds it.

That is to say, if you save a context with setjmp, then alloca some memory, then longjmp to the context, you may lose the alloca memory. The stack pointer is back where it was and so the memory is no longer reserved; if you call a function or do another alloca, you will clobber the original alloca.

To clarify, what I'm specifically referring to here is a situation whereby longjmp does not return out of the function where the alloca took place! Rather, a function saves context with setjmp; then allocates memory with alloca and finally a longjmp takes place to that context. That function's alloca memory is not all freed; just all the memory that it allocated since the setjmp. Of course, I'm speaking about an observed behavior; no such requirement is documented of any alloca that I know.

The focus in the documentation is usually on the concept that alloca memory is associated with a function activation, not with any block; that multiple invocations of alloca just grab more stack memory which is all released when the function terminates. Not so; the memory is actually associated with the procedure context. When the context is restored with longjmp, so is the prior alloca state. It's a consequence of the stack pointer register itself being used for allocation, and also (necessarily) saved and restored in the jmp_buf.

Incidentally, this, if it works that way, provides a plausible mechanism for deliberately freeing memory that was allocated with alloca.

I have run into this as the root cause of a bug.

Use the rename utility written in perl. Might be that it is not available by default though...

$ touch 0{5..6}_h.png

$ ls
05_h.png  06_h.png

$ rename 's/h/half/' *.png

$ ls
05_half.png  06_half.png

The console.log should be wrapped in a function , the "default" function for every class is its constructor so it should be declared there.

import { Component } from '@angular/core';
console.log("Hello1");

 @Component({
  selector: 'hello-console',
})
    export class App {
     s: string = "Hello2";
    constructor(){
     console.log(s); 
    }

}

UPDATE: That a reboot helped was coincidental (I hoped so, hooray!). The real cause of the problem was this: When Gradle is directed to use a specific keystore, that keystore must also contain all the official root certificates. Otherwise it cannot access libraries from regular repositories. What I had to do was this:

Import the self-signed certificate:

keytool -import -trustcacerts -alias myselfsignedcert -file /Users/me/Desktop/selfsignedcert.crt -keystore ./privateKeystore.jks

Add the official root certificates:

keytool -importkeystore -srckeystore <java-home>/lib/security/cacerts -destkeystore ./privateKeystore.jks

Maybe the Gradle daemon also got in the way. Might be worth killing all running daemons found with ./gradlew --status if things start looking bleak.

ORIGINAL POSTING:

Nobody will believe this, I know. Still, if all else fails, give it a try: After a reboot of my Mac the problem was gone. Grrr.

Background: ./gradlew jar kept giving me "unable to find valid certification path to requested target"

I am stuck with a self-signed certificate, saved from browser, imported in privateKeystore.jks. Then instructed Gradle to work with privateKeystore.jks:

org.gradle.jvmargs=-Djavax.net.debug=SSL -Djavax.net.ssl.trustStore="/Users/me/IntelliJ/myproject/privateKeystore.jks"  -Djavax.net.ssl.trustStorePassword=changeit

As mentioned, this only worked after a reboot.

Java binaries may be under "Program Files" or "Program Files (x86)": those white spaces will likely affect the behaviour.

In order to set up env variables correctly, I suggest gathering some info before starting:

• Open DOS shell (type cmd into 'RUN' box) go to C:\
• type "dir /x" and take note of DOS names (with ~) for "Program Files *" folders

Cygwin configuration:

go under C:\cygwin\home\, then open .bash_profile and add the following two lines (conveniently customized in order to match you actual JDK path)

export JAVA_HOME="/cygdrive/c/PROGRA~1/Java/jdk1.8.0_65"
export PATH="$JAVA_HOME/bin:$PATH"

Now from Cygwin launch

javac -version

to check if the configuration is successful.

You would get a type mismatch if Sheets(name).Cells(4 + i, 57) contains a non-numeric value. You should validate the fields before you assume they are numbers and try to subtract from them.

Also, you should enable Option Strict so you are forced to explicitly convert your variables before trying to perform type-dependent operations on them such as subtraction. That will help you identify and eliminate issues in the future, too.    Unfortunately Option Strict is for VB.NET only. Still, you should look up best practices for explicit data type conversions in VBA.

Update:

If you are trying to go for the quick fix of your code, however, wrap the ** line and the one following it in the following condition:

If IsNumeric(Sheets(name).Cells(4 + i, 57))
    Sheets(name).Cells(4 + i, 58) = Sheets(name).Cells(4 + i, 57) - a
    x = Sheets(name).Cells(4 + i, 57) - a
End If

Note that your x value may not contain its expected value in the next iteration, however.

Since API 24 you have FROM_HTML_OPTION_USE_CSS_COLORS so you can define colors in CSS instead of repeating it all time with font color=" Much clearer - when you have some html and you want to highlight some predefined tags - you just need to add CSS fragment at top of your html

This:

function myfunction()
{
     if (a == 'stop')  // How can I stop working of function here?
     {
         return;
     }
}

Adding a new answer just as a reference for future researchers and as nobody mentioned that yet I think it's valid.

Another good option is ng-grid http://angular-ui.github.io/ng-grid/.

And there's a beta version (http://ui-grid.info/) available already with some improvements:

• Native AngularJS implementation, no jQuery
• Performs well with large data sets; even 10,000+ rows
• Plugin architecture allows you to use only the features you need

UPDATE:

It seems UI GRID is not beta anymore.

With the 3.0 release, the repository has been renamed from "ng-grid" to "ui-grid".

What worked for me was:

$('select option').each(function(){$(this).removeAttr('selected');});   

select sequence_owner, sequence_name from dba_sequences;


DBA_SEQUENCES -- all sequences that exist 
ALL_SEQUENCES  -- all sequences that you have permission to see 
USER_SEQUENCES  -- all sequences that you own

Note that since you are, by definition, the owner of all the sequences returned from USER_SEQUENCES, there is no SEQUENCE_OWNER column in USER_SEQUENCES.

String[] tblHead={"Item Name","Price","Qty","Discount"};
DefaultTableModel dtm=new DefaultTableModel(tblHead,0);
JTable tbl=new JTable(dtm);
String[] item={"A","B","C","D"};
dtm.addRow(item);

Here;this is the solution.

You must type in the same name in your select query as your entity or class(case sensitive) . i.e. select user from className/Entity Name user;

I don't know of any git command that gives a "bad" exit code, but it seems like an easy way to do it would be to use a git command that gives no output for a file that isn't tracked, such as git-log or git-ls-files. That way you don't really have to do any parsing, you can run it through another simple utility like grep to see if there was any output.

For example,

git-ls-files test_file.c | grep .

will exit with a zero code if the file is tracked, but a exit code of one if the file is not tracked.

The servlet container loads the servlet during startup or when the first request is made. The loading of the servlet depends on the attribute "load-on-startup" in "web.xml" file. If the attribute has a positive integer(0 to 128) then the servlet is load with the loading of the container otherwise it loads when the first request comes for service.

When the servlet is loaded once it gets request then it is called "Lazy loading".

regex solution (The best way is the solution by @Elazar this is just for fun)

import re
def remove_prefix(text, prefix):
    return re.sub(r'^{0}'.format(re.escape(prefix)), '', text)

>>> print remove_prefix('template.extensions', 'template.')
extensions

In Vim, use :insert. This will keep all your formatting and not do autoindenting. For more information help :insert.

All these answers are correct, but I had to also check if the string contains other characters and Hebrew letters so I simply used:

if (!str.match(/^[\d]+$/)) {
    //contains other characters as well
}

Use the map() function native on JavaScript arrays:

var yourArray = [ {
    'id':1,
    'name':'john'
},{
    'id':2,
    'name':'jane'
}........,{
    'id':2000,
    'name':'zack'
}];

var newArray = yourArray.map( function( el ){ 
                                return el.name; 
                               });

Here is a theme that I copied all the important parts of the Visual Studio 2013 dark theme.

**Update 08/Sep/15 - Qt Creator 3.5.1/Qt 5.5.1 might have fixed the rest of Qt not being dark properly and hard to read.

Intuitively:

"The complexity should be O(nLog n)... for each item we "heapify", it has the potential to have to filter down once for each level for the heap so far (which is log n levels)."

Not quite. Your logic does not produce a tight bound -- it over estimates the complexity of each heapify. If built from the bottom up, insertion (heapify) can be much less than O(log(n)). The process is as follows:

( Step 1 ) The first n/2 elements go on the bottom row of the heap. h=0, so heapify is not needed.

( Step 2 ) The next n/22 elements go on the row 1 up from the bottom. h=1, heapify filters 1 level down.

( Step i ) The next n/2i elements go in row i up from the bottom. h=i, heapify filters i levels down.

( Step log(n) ) The last n/2log2(n) = 1 element goes in row log(n) up from the bottom. h=log(n), heapify filters log(n) levels down.

NOTICE: that after step one, 1/2 of the elements (n/2) are already in the heap, and we didn't even need to call heapify once. Also, notice that only a single element, the root, actually incurs the full log(n) complexity.

Theoretically:

The Total steps N to build a heap of size n, can be written out mathematically.

At height i, we've shown (above) that there will be n/2i+1 elements that need to call heapify, and we know heapify at height i is O(i). This gives:

The solution to the last summation can be found by taking the derivative of both sides of the well known geometric series equation:

Finally, plugging in x = 1/2 into the above equation yields 2. Plugging this into the first equation gives:

Thus, the total number of steps is of size O(n)

It's only supposed to send the information to the server. The reason that it must preceed the file field is that it has to come before the file payload in the request for the server to be able to use it to check the size of the upload.

How the value is used on the server depends on what you use to take care of the upload. The code is supposedly intended for a specific upload component that specifically looks for that value.

It seems that the built in upload support in PHP is one to use this field value.

If you need to resume an scp transfer from local to remote, try with rsync:

rsync --partial --progress --rsh=ssh local_file user@host:remote_file

Short version, as pointed out by @aurelijus-rozenas:

rsync -P -e ssh local_file user@host:remote_file

In general the order of args for rsync is

rsync [options] SRC DEST

With recent versions of Matlab, you can use the Table data structure to your advantage. There's even a 'rowfun' operation but I found it easier just to do this:

a = magic(6);
incrementRow = cell2mat(cellfun(@(x) x+1,table2cell(table(a)),'UniformOutput',0))

or here's an older one I had that doesn't require tables, for older Matlab versions.

dataBinner = cell2mat(arrayfun(@(x) Binner(a(x,:),2)',1:size(a,1),'UniformOutput',0)')

I was facing the same problem. This way I was able to solved it. As CQM said, using Color.parseColor() is a good solution to this issue.

Here is the code I used:

this.Button_C.setTextColor(Color.parseColor(prefs.getString("color_prefs", String.valueOf(R.color.green))));

In this case my target was to change the Button's text color (Button_C) when I change the color selection from my Preferences (color_prefs).

If you have tried all the other answers, and it still hasn't work, you can try skipping a line:

Scanner scan = new Scanner(System.in);
scan.nextLine();
String s = scan.nextLine();
System.out.println("String is " + s);

you may try this:-

myImgView.setImageDrawable(getResources().getDrawable(R.drawable.image_name));

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

Hope this will help you. I am using this solution for Search on some columns but i don't want to display them on frontend.

I've learned to not try to outsmart the garbage collection. With that said, I just stick to using using keyword when dealing with unmanaged resources like file I/O or database connections.

In Visual Basic, do this to select a row in a DataGridView; the selected row will appear with a highlighted color but note that the cursor position will not change:

Grid.Rows(0).Selected = True

Do this change the position of the cursor:

Grid.CurrentCell = Grid.Rows(0).Cells(0)

Combining the lines above will position the cursor and select a row. This is the standard procedure for focusing and selecting a row in a DataGridView:

Grid.CurrentCell = Grid.Rows(0).Cells(0)
Grid.Rows(0).Selected = True

I'm surprised no one mentioned the possibility to use an API to do the work.

Granted, if you want to stay secure, converting HTML to PDF directly from within the browser using javascript is not a good idea.

But here's what you can do:

When your user hit the "Print" (for example) button, you:

1. Send a request to your server at a specific endpoint with details about what to convert (URL of the page for instance).
2. This endpoint will then send the data to convert to an API, and will receive the PDF in response
3. which it will return to your user.

For a user point of view, they will receive a PDF by clicking on a button.

There are many available API that does the job, some better than others (that's not why I'm here) and a Google search will give you a lot of answers.

Depending on what is written your backend, you might be interested in PDFShift (Truth: I work there).

They offer ready to work packages for PHP, Python and Node.js. All you have to do is install the package, create an account, indicate your API key and you are all set!

The advantage of the API is that they work well in all languages. All you have to do is a request (generally POST) containing the data you want to be converted and get a PDF back. And depending on your usage, it's generally free, except if you are a heavy user.

CentOS is Linux, so as in just about all other Unix/Linux systems, you have the find command. To search for files within the current directory:

find -name "filename"

You can also have wildcards inside the quotes, and not just a strict filename. You can also explicitly specify a directory to start searching from as the first argument to find:

find / -name "filename"

will look for "filename" or all the files that match the regex expression in between the quotes, starting from the root directory. You can also use single quotes instead of double quotes, but in most cases you don't need either one, so the above commands will work without any quotes as well. Also, for example, if you're searching for java files and you know they are somewhere in your /home/username, do:

find /home/username -name *.java

There are many more options to the find command and you should do a:

man find

to learn more about it.

One more thing: if you start searching from / and are not root or are not sudo running the command, you might get warnings that you don't have permission to read certain directories. To ignore/remove those, do:

find / -name 'filename' 2>/dev/null

That just redirects the stderr to /dev/null.

Well if you know the basics behind them, it shouldn't be too hard.

Generally you create an array called "buckets" that contain the key and value, with an optional pointer to create a linked list.

When you access the hash table with a key, you process the key with a custom hash function which will return an integer. You then take the modulus of the result and that is the location of your array index or "bucket". Then you check the unhashed key with the stored key, and if it matches, then you found the right place.

Otherwise, you've had a "collision" and must crawl through the linked list and compare keys until you match. (note some implementations use a binary tree instead of linked list for collisions).

Check out this fast hash table implementation:

https://attractivechaos.wordpress.com/2009/09/29/khash-h/

foreach (var f in Directory.GetFiles(".", "*.dll"))
            Assembly.LoadFrom(f);

That loads all the DLLs present in your executable's folder.

In my case I was trying to use Reflection to find all subclasses of a class, even in other DLLs. This worked, but I'm not sure if it's the best way to do it.

EDIT: I timed it, and it only seems to load them the first time.

Stopwatch stopwatch = new Stopwatch();
for (int i = 0; i < 4; i++)
{
    stopwatch.Restart();
    foreach (var f in Directory.GetFiles(".", "*.dll"))
        Assembly.LoadFrom(f);
    stopwatch.Stop();
    Console.WriteLine(stopwatch.ElapsedMilliseconds);
}

Output: 34 0 0 0

So one could potentially run that code before any Reflection searches just in case.

I had this issue too.

It started after I did a little folder tidying in my project. I then tried to compile and got many duplicate class errors. (despite them not being duplicated. I think the linking was just out of wack)

Upon checking these, the errors would all disappear leaving only the "Metadata file ...debug\application.exe could not be found" error.

I solved this by looking in the build output window to find which classes were duplicated.

I would then right click the class name and "go to definition".

there will be two definitions to select from, open them both, the second definition will seem to open the same file again, however the second one will identify as the error source(red underline).

Delete all the code out of the file and save(This will not effect your actual file).
This should now compile correctly.

Here's some code from Excel 2010 that may work. It has a couple specifics (like filtering bad-encode characters from titles) but it was designed to create multiple multi-series graphs from 4-dimensional data having both absolute and percentage-based data. Modify it how you like:

1. Observer pattern throughout whole swing (Observable, Observer)
2. MVC also in swing
3. Adapter pattern: InputStreamReader and OutputStreamWriter NOTE: ContainerAdapter, ComponentAdapter, FocusAdapter, KeyAdapter, MouseAdapter are not adapters; they are actually Null Objects. Poor naming choice by Sun.
4. Decorator pattern (BufferedInputStream can decorate other streams such as FilterInputStream)
5. AbstractFactory Pattern for the AWT Toolkit and the Swing pluggable look-and-feel classes
6. java.lang.Runtime#getRuntime() is Singleton
7. ButtonGroup for Mediator pattern
8. Action, AbstractAction may be used for different visual representations to execute same code -> Command pattern
9. Interned Strings or CellRender in JTable for Flyweight Pattern (Also think about various pools - Thread pools, connection pools, EJB object pools - Flyweight is really about management of shared resources)
10. The Java 1.0 event model is an example of Chain of Responsibility, as are Servlet Filters.
11. Iterator pattern in Collections Framework
12. Nested containers in AWT/Swing use the Composite pattern
13. Layout Managers in AWT/Swing are an example of Strategy

and many more I guess

here we console natural number 0 to ......n (next number print in console every 60 sec.) , using setInterval()

I hate messy fields in my databases. If the column might be a blank string or null, I'd rather fix this before doing the select each time, like this:

UPDATE MyTable SET MyColumn=NULL WHERE MyColumn='';
SELECT * FROM MyTable WHERE MyColumn IS NULL

This keeps the data tidy, as long as you don't specifically need to differentiate between NULL and empty for some reason.

Non-inherited elements must have default styles set.
If parent class set color:white and font-weight:bold style then no inherited child must set 'color:black' and font-weight: normal in their class. If style is not set, elements get their style from their parents.

<select name="forma" onchange="location = this.value;">

UPDATE (Nov 2015): In this day and age if you want to have a drop menu there are plenty of arguably better ways to implement one. This answer is a direct answer to a direct question, but I don't advocate this method for public facing web sites.

UPDATE (May 2020): Someone asked in the comments why I wouldn't advocate this solution. I guess it's a question of semantics. I'd rather my users navigate using <a> and kept <select> for making form selections because HTML elements have semantic meeting and they have a purpose, anchors take you places, <select> are for picking things from lists.

Consider, if you are viewing a page with a non-traditional browser (a non graphical browser or screen reader or the page is accessed programmatically, or JavaScript is disabled) what then is the "meaning" or the "intent" of this <select> you have used for navigation? It is saying "please pick a page name" and not a lot else, certainly nothing about navigating. The easy response to this is well i know that my users will be using IE or whatever so shrug but this kinda misses the point of semantic importance.

Whereas a funky drop-down UI element made of suitable layout elements (and some js) containing some regular anchors still retains it intent even if the layout element is lost, "these are a bunch of links, select one and we will navigate there".

Here is an article on the misuse and abuse of <select>.

I tried all the above answers, but inserting or removing items to recyclerview causes problem with the position in the dataSet. Ended up using delete(getAdapterPosition()); inside the viewHolder which worked great at finding the position of items.

Hopefully this helps someone out there.

For platform I was specifying "Any CPU", changed it to "AnyCPU" and that fixed the problem.

msbuild C:\Users\Project\Project.publishproj /p:Platform="AnyCPU"  /p:DeployOnBuild=true /p:PublishProfile=local /p:Configuration=Debug

If you look at your .csproj file you'll see the correct platform name to use.

Use a timer with an interval set to 2–3 seconds.

You have three different options to choose from, depending on which type of application you're writing:

1. System.Timers.Timer
2. System.Windows.Forms.Timer
3. System.Threading.Timer

Don't use Thread.Sleep if your application need to process any inputs on that thread at the same time (WinForms, WPF), as Sleep will completely lock up the thread and prevent it from processing other messages. Assuming a single-threaded application (as most are), your entire application will stop responding, rather than just delaying an operation as you probably intended. Note that it may be fine to use Sleep in pure console application as there are no "events" to handle or on separate thread (also Task.Delay is better option).

In addition to timers and Sleep you can use Task.Delay which is asynchronous version of Sleep that does not block thread from processing events (if used properly - don't turn it into infinite sleep with .Wait()).

 public async void ClickHandler(...)
 {
      // whatever you need to do before delay goes here         

      await Task.Delay(2000);

      // whatever you need to do after delay.
 }

The same await Task.Delay(2000) can be used in a Main method of a console application if you use C# 7.1 (Async main on MSDN blogs).

Note: delaying operation with Sleep has benefit of avoiding race conditions that comes from potentially starting multiple operations with timers/Delay. Unfortunately freezing UI-based application is not acceptable so you need to think about what will happen if you start multiple delays (i.e. if it is triggered by a button click) - consider disabling such button, or canceling the timer/task or making sure delayed operation can be done multiple times safely.

You can also do this much easier with a plugin called jQuery-confirm. All you have to do is add the script tag and the style sheet they provide in your page

<link rel="stylesheet" 
href="https://cdnjs.cloudflare.com/ajax/libs/jquery-
confirm/3.3.0/jquery-confirm.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-
confirm/3.3.0/jquery-confirm.min.js"></script>

And then an example of calling the alert box is:

   <script>
        $.alert({
    title: 'Alert!',
    content: 'Simple alert!',
     });

I found an easy and nice solution:

char*string_acquire(char*s,int size,FILE*stream){
    int i;
    fgets(s,size,stream);
    i=strlen(s)-1;
    if(s[i]!='\n') while(getchar()!='\n');
    if(s[i]=='\n') s[i]='\0';
    return s;
}

it's based on fgets but free from '\n' and stdin extra characters (to replace fflush(stdin) that doesn't works on all OS, useful if you have to acquire strings after this).

There's no need for Prototype here: JavaScript has for..in loops. If you're not sure that no one messed with Object.prototype, check hasOwnProperty() as well, ie

for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
        doSomethingWith(obj[prop]);
}

The extreme and simple cases:

• A compiler will produce a binary executable in the target machine's native executable format. This binary file contains all required resources except for system libraries; it's ready to run with no further preparation and processing and it runs like lightning because the code is the native code for the CPU on the target machine.

• An interpreter will present the user with a prompt in a loop where he can enter statements or code, and upon hitting RUN or the equivalent the interpreter will examine, scan, parse and interpretatively execute each line until the program runs to a stopping point or an error. Because each line is treated on its own and the interpreter doesn't "learn" anything from having seen the line before, the effort of converting human-readable language to machine instructions is incurred every time for every line, so it's dog slow. On the bright side, the user can inspect and otherwise interact with his program in all kinds of ways: Changing variables, changing code, running in trace or debug modes... whatever.

With those out of the way, let me explain that life ain't so simple any more. For instance,

• Many interpreters will pre-compile the code they're given so the translation step doesn't have to be repeated again and again.
• Some compilers compile not to CPU-specific machine instructions but to bytecode, a kind of artificial machine code for a ficticious machine. This makes the compiled program a bit more portable, but requires a bytecode interpreter on every target system.
• The bytecode interpreters (I'm looking at Java here) recently tend to re-compile the bytecode they get for the CPU of the target section just before execution (called JIT). To save time, this is often only done for code that runs often (hotspots).
• Some systems that look and act like interpreters (Clojure, for instance) compile any code they get, immediately, but allow interactive access to the program's environment. That's basically the convenience of interpreters with the speed of binary compilation.
• Some compilers don't really compile, they just pre-digest and compress code. I heard a while back that's how Perl works. So sometimes the compiler is just doing a bit of the work and most of it is still interpretation.

In the end, these days, interpreting vs. compiling is a trade-off, with time spent (once) compiling often being rewarded by better runtime performance, but an interpretative environment giving more opportunities for interaction. Compiling vs. interpreting is mostly a matter of how the work of "understanding" the program is divided up between different processes, and the line is a bit blurry these days as languages and products try to offer the best of both worlds.

I would use FMOD to do this for your game. It has the ability to play any file mostly for sounds and is pretty simple to implement in C++. using FMOD and Dir3ect X together can be powerful and not that difficult. If you are familiar with Singleton classes I would create a Singleton class of a sound manager in your win main cpp and then have access to it whenever to load or play new music or sound effects. here's an audio manager example

    #pragma once

#include "fmod_memoryinfo.h"
#include "fmod_output.h"

class AudioManager
{

Do you plan to have a squared UIView of width: 100 and Height: 100 centered inside the UIView of an UIViewController? If so, you may try one of the 6 following Auto Layout styles (Swift 5 / iOS 12.2):

1. Using NSLayoutConstraint initializer

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    let widthConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    let heightConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    view.addConstraints([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    let widthConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    let heightConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100).isActive = true
}

2. Using Visual Format Language

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["view": view!, "newView": newView]
    let horizontalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterY, metrics: nil, views: views)
    let verticalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterX, metrics: nil, views: views)
    view.addConstraints(horizontalConstraints)
    view.addConstraints(verticalConstraints)
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["view": view!, "newView": newView]
    let horizontalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterY, metrics: nil, views: views)
    let verticalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterX, metrics: nil, views: views)
    NSLayoutConstraint.activate(horizontalConstraints)
    NSLayoutConstraint.activate(verticalConstraints)
}

3. Using a mix of NSLayoutConstraint initializer and Visual Format Language

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["newView": newView]
    let widthConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let heightConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    view.addConstraints(widthConstraints)
    view.addConstraints(heightConstraints)
    view.addConstraints([horizontalConstraint, verticalConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["newView": newView]
    let widthConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let heightConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    NSLayoutConstraint.activate(widthConstraints)
    NSLayoutConstraint.activate(heightConstraints)
    NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["newView": newView]
    let widthConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let heightConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    NSLayoutConstraint.activate(widthConstraints)
    NSLayoutConstraint.activate(heightConstraints)
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true
}

4. Using UIView.AutoresizingMask

Note: Springs and Struts will be translated into corresponding auto layout constraints at runtime.

override func viewDidLoad() {
    let newView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = true
    newView.center = CGPoint(x: view.bounds.midX, y: view.bounds.midY)
    newView.autoresizingMask = [UIView.AutoresizingMask.flexibleLeftMargin, UIView.AutoresizingMask.flexibleRightMargin, UIView.AutoresizingMask.flexibleTopMargin, UIView.AutoresizingMask.flexibleBottomMargin]
}

5. Using NSLayoutAnchor

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)
    
    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = newView.centerXAnchor.constraint(equalTo: view.centerXAnchor)
    let verticalConstraint = newView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
    let widthConstraint = newView.widthAnchor.constraint(equalToConstant: 100)
    let heightConstraint = newView.heightAnchor.constraint(equalToConstant: 100)
    view.addConstraints([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)
    
    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = newView.centerXAnchor.constraint(equalTo: view.centerXAnchor)
    let verticalConstraint = newView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
    let widthConstraint = newView.widthAnchor.constraint(equalToConstant: 100)
    let heightConstraint = newView.heightAnchor.constraint(equalToConstant: 100)
    NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)
    
    newView.translatesAutoresizingMaskIntoConstraints = false
    newView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    newView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
    newView.widthAnchor.constraint(equalToConstant: 100).isActive = true
    newView.heightAnchor.constraint(equalToConstant: 100).isActive = true
}

6. Using intrinsicContentSize and NSLayoutAnchor

import UIKit

class CustomView: UIView {
    
    override var intrinsicContentSize: CGSize {
        return CGSize(width: 100, height: 100)
    }
    
}

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        let newView = CustomView()
        newView.backgroundColor = UIColor.red
        view.addSubview(newView)
        
        newView.translatesAutoresizingMaskIntoConstraints = false
        let horizontalConstraint = newView.centerXAnchor.constraint(equalTo: view.centerXAnchor)
        let verticalConstraint = newView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
        NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint])
    }
    
}

Result:

You simply need to do a SUBSTR on the string in col3....

    Select col1, col2, REPLACE(substr(col3, instr(col3, 'Client Name'), 
    (instr(col3, '|', instr(col3, 'Client Name')  -
    instr(col3, 'Client Name'))
    ),
'Client Name = ',
'')
    from Table01 

And yes, that is a bad DB design for the reasons stated in the original issue

Pythonic duck-typing should in principle determine what an object can do, i.e., its properties and methods. By looking at a dictionary object one may try to guess it has at least one of the following: dict.keys() or dict.values() methods. You should try to use this approach for future work with programming languages whose type checking occurs at runtime, especially those with the duck-typing nature.

Run make -n; it shows you the value of the variable..

Makefile...

all:
        @echo $(NDK_PROJECT_PATH)

Command:

export NDK_PROJECT_PATH=/opt/ndk/project
make -n 

Output:

echo /opt/ndk/project

To update each submodule, you could invoke the following command (at the root of the repository):

git submodule -q foreach git pull -q origin master

You can remove the -q option to follow the whole process.

Compare getApplication() and getApplicationContext().

getApplication returns an Application object which will allow you to manage your global application state and respond to some device situations such as onLowMemory() and onConfigurationChanged().

getApplicationContext returns the global application context - the difference from other contexts is that for example, an activity context may be destroyed (or otherwise made unavailable) by Android when your activity ends. The Application context remains available all the while your Application object exists (which is not tied to a specific Activity) so you can use this for things like Notifications that require a context that will be available for longer periods and independent of transient UI objects.

I guess it depends on what your code is doing whether these may or may not be the same - though in normal use, I'd expect them to be different.

In /etc/apache2/ports.conf, change the port as

Listen 8079

Then go to /etc/apache2/sites-enabled/000-default.conf

And change the first line as

<VirtualHost *: 8079>

Now restart

sudo service apache2 restart

Apache will now listen on port 8079 and redirect to /var/www/html

On saveAndFlush, changes will be flushed to DB immediately in this command. With save, this is not necessarily true, and might stay just in memory, until flush or commit commands are issued.

But be aware, that even if you flush the changes in transaction and do not commit them, the changes still won't be visible to the outside transactions until the commit in this transaction.

In your case, you probably use some sort of transactions mechanism, which issues commit command for you if everything works out fine.

You should not attempt to parse HTML with regex. HTML is not a regular language, so any regex you come up with will likely fail on some esoteric edge case. Please refer to the seminal answer to this question for specifics. While mostly formatted as a joke, it makes a very good point.

The following examples are Java, but the regex will be similar -- if not identical -- for other languages.

String target = someString.replaceAll("<[^>]*>", "");

Assuming your non-html does not contain any < or > and that your input string is correctly structured.

If you know they're a specific tag -- for example you know the text contains only <td> tags, you could do something like this:

String target = someString.replaceAll("(?i)<td[^>]*>", "");

Edit: Omega brought up a good point in a comment on another post that this would result in multiple results all being squished together if there were multiple tags.

For example, if the input string were <td>Something</td><td>Another Thing</td>, then the above would result in SomethingAnother Thing.

In a situation where multiple tags are expected, we could do something like:

String target = someString.replaceAll("(?i)<td[^>]*>", " ").replaceAll("\\s+", " ").trim();

This replaces the HTML with a single space, then collapses whitespace, and then trims any on the ends.

Another option is to use a regex and gsub, which takes a block:

'one TWO three foUR'.gsub(/\w+/, &:capitalize)

I know it has been a long time since the original question was posted. But i think for slow ones like me a bit of explanation of @Heisenberg's answer would help.

Declare two variable in the adapter class as

private int mExpandedPosition= -1;
private RecyclerView recyclerView = null;

Then in onBindViewHolder following as given in the original answer.

      // This line checks if the item displayed on screen 
      // was expanded or not (Remembering the fact that Recycler View )
      // reuses views so onBindViewHolder will be called for all
      // items visible on screen.
    final boolean isExpanded = position==mExpandedPosition;

        //This line hides or shows the layout in question
        holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);

        // I do not know what the heck this is :)
        holder.itemView.setActivated(isExpanded);

        // Click event for each item (itemView is an in-built variable of holder class)
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

 // if the clicked item is already expaned then return -1 
//else return the position (this works with notifyDatasetchanged )
                mExpandedPosition = isExpanded ? -1:position;
    // fancy animations can skip if like
                TransitionManager.beginDelayedTransition(recyclerView);
    //This will call the onBindViewHolder for all the itemViews on Screen
                notifyDataSetChanged();
            }
        });

And lastly to get the recyclerView object in the adapter override

@Override
public void onAttachedToRecyclerView(@NonNull RecyclerView recyclerView) {
    super.onAttachedToRecyclerView(recyclerView);

    this.recyclerView = recyclerView;
}

Hope this Helps.

I guess no one mentioned this so I will write it here. In phpMyAdmin 4.x, there is "Add Routine" link under "Routines" tab at the top row. This link opens a popup dialog where you can write your Stored procedure without worrying about delimiter or template.

Add Routine

Note that for simple test stored procedure, you may want to drop the default parameter which is already given or you can simply set it with a value.

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

/*USE THIS SCRIPT */

var today = new Date();
var first = new Date(today.getFullYear(), 0, 1);
var theDay = Math.round(((today - first) / 1000 / 60 / 60 / 24) + .5, 0);
alert("Today is the " + theDay + (theDay == 1 ? "st" : (theDay == 2 ? "nd" : (theDay == 3 ? "rd" : "th"))) + " day of the year");

In stall PuTTY in our system and set the environment variable PATH Pointing to putty path. open the command prompt and move to putty folder. Using PSCP command

Please check this

Shortest Yet !!!

=f.hidden_field :title, :value => "some value"

Shorter, DRYer and perhaps more obvious.

Of course with ruby 1.9 and the new hash format we can go 3 characters shorter with...

=f.hidden_field :title, value: "some value"

Funnily enough, adjusting the padding seems to do it.

.arrow {
  border: solid rgb(2, 0, 0);
  border-width: 0 3px 3px 0;
  display: inline-block;
}

.first{
  padding: 2vh;
}

.second{
  padding: 4vh;
}

.left {
    transform: rotate(135deg);
    -webkit-transform: rotate(135deg);
 }

<i class="arrow first left"></i>
<i class="arrow second left"></i>

I like to use the program Artistic Style. According to their website:

Artistic Style is a source code indenter, formatter, and beautifier for the C, C++, C# and Java programming languages.

It runs in Window, Linux and Mac. It will do things like indenting, replacing tabs with spaces or vice-versa, putting spaces around operations however you like (converting if(x<2) to if ( x<2 ) if that's how you like it), putting braces on the same line as function definitions, or moving them to the line below, etc. All the options are controlled by command line parameters.

In order to use it in vim, just set the formatprg option to it, and then use the gq command. So, for example, I have in my .vimrc:

autocmd BufNewFile,BufRead *.cpp set formatprg=astyle\ -T4pb

so that whenever I open a .cpp file, formatprg is set with the options I like. Then, I can type gg to go to the top of the file, and gqG to format the entire file according to my standards. If I only need to reformat a single function, I can go to the top of the function, then type gq][ and it will reformat just that function.

The options I have for astyle, -T4pb, are just my preferences. You can look through their docs, and change the options to have it format the code however you like.

Here's a demo. Before astyle:

int main(){if(x<2){x=3;}}

float test()
{
if(x<2)
x=3;
}

After astyle (gggqG):

int main()
{
    if (x < 2)
    {
        x = 3;
    }
}

float test()
{
    if (x < 2)
        x = 3;
}

Hope that helps.

When you have repeated notifications at future, you do not want to cancel those notifications, you can clear the item in notification center by:

func clearNotificationCenter() {
    UIApplication.sharedApplication().applicationIconBadgeNumber = 1
    UIApplication.sharedApplication().applicationIconBadgeNumber = 0
}

You cannot clear notification when your app is open in the foreground by calling the method below immediately after receiving local notification, otherwise you will receive tens of hundreds of notifications. Maybe because the same notification apply again, and now is the time to fire, so you keep fire, apply again, fire, apply....:

[UIApplication sharedApplication].scheduledLocalNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;

Add Thread.sleep

Although the question was asked quite long time ago, writing this answer with hope it will help somebody.

Pass the date you want to start to count from. Using moment().fromNow() of momentjs: (See more information here)

getRelativeTime(date) {
    const d = new Date(date * 1000);
    return moment(d).fromNow();
}

If you want to change information provided for dates fromNow you write your custom relative time for moment.

For example, in my own case I wanted to print 'one month ago' instead of 'a month ago' (provided by moment(d).fromNow()). In this case, you can write something given below.

moment.updateLocale('en', {
    relativeTime: {
        future: 'in %s',
        past: '%s ago',
        s: 'a few seconds',
        ss: '%d seconds',
        m: '1 m',
        mm: '%d minutes',
        h: '1 h',
        hh: '%d hours',
        d: '1 d',
        dd: '%d days',
        M: '1 month',
        MM: '%d months',
        y: '1 y',
        yy: '%d years'
    }
});

NOTE: I wrote my code for project in Angular 6

Underscore-java keeps orders for elements while reading json. I am the maintainer of the project.

String json = "{\n"
      + "    \"items\":\n"
      + "    [\n"
      + "        {\n"
      + "            \"WR\":\"qwe\",\n"
      + "            \"QU\":\"asd\",\n"
      + "            \"QA\":\"end\",\n"
      + "            \"WO\":\"hasd\",\n"
      + "            \"NO\":\"qwer\"\n"
      + "        }\n"
      + "    ]\n"
      + "}";
System.out.println(U.fromJson(json));

// {items=[{WR=qwe, QU=asd, QA=end, WO=hasd, NO=qwer}]}

You don't. The C++ standard has no concept of directories. It is up to the implementation to turn a string into a file handle. The contents of that string and what it maps to is OS dependent. Keep in mind that C++ can be used to write that OS, so it gets used at a level where asking how to iterate through a directory is not yet defined (because you are writing the directory management code).

Look at your OS API documentation for how to do this. If you need to be portable, you will have to have a bunch of #ifdefs for various OSes.

If you want to manipulate the form programmatically the simplest solution is to keep a reference to it:

static Form myForm;

static void Main()
{
    myForm = new Form();
    Application.Run(myForm);
}

You can then use that to change the size (or what ever else you want to do) at run time. Though as Arrow points out you can't set the Width and Height directly but have to set the Size property.

Here are several benefits of IHttpActionResult over HttpResponseMessage mentioned in Microsoft ASP.Net Documentation:

• Simplifies unit testing your controllers.
• Moves common logic for creating HTTP responses into separate classes.
• Makes the intent of the controller action clearer, by hiding the low-level details of constructing the response.

But here are some other advantages of using IHttpActionResult worth mentioning:

• Respecting single responsibility principle: cause action methods to have the responsibility of serving the HTTP requests and does not involve them in creating the HTTP response messages.
• Useful implementations already defined in the System.Web.Http.Results namely: Ok NotFound Exception Unauthorized BadRequest Conflict Redirect InvalidModelState (link to full list)
• Uses Async and Await by default.
• Easy to create own ActionResult just by implementing ExecuteAsync method.
• you can use ResponseMessageResult ResponseMessage(HttpResponseMessage response) to convert HttpResponseMessage to IHttpActionResult.

another way is to use the range method

foo = [1,2,3,4,5,6]
bar = [10,20,30,40,50,60]
a = foo[0...3]
b = bar[3...6]

print a + b 
=> [1, 2, 3, 40, 50 , 60]

Try this:

sys.getsizeof(object)

getsizeof() Return the size of an object in bytes. It calls the object’s __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.

A recursive recipe

Here's an extension function:

        public static string ToBinary(this string data, bool formatBits = false)
        {
            char[] buffer = new char[(((data.Length * 8) + (formatBits ? (data.Length - 1) : 0)))];
            int index = 0;
            for (int i = 0; i < data.Length; i++)
            {
                string binary = Convert.ToString(data[i], 2).PadLeft(8, '0');
                for (int j = 0; j < 8; j++)
                {
                    buffer[index] = binary[j];
                    index++;
                }
                if (formatBits && i < (data.Length - 1))
                {
                    buffer[index] = ' ';
                    index++;
                }
            }
            return new string(buffer);
        }

You can use it like:

Console.WriteLine("Testing".ToBinary());

and if you add 'true' as a parameter, it will automatically separate each binary sequence.

it works

Add this inside your head tag

<link rel="shortcut icon" href="http://example.com/myicon.png" />

If you want to take control of /usr/bin/

You will need to reboot your system:

Right after the boot sound, Hold down Command-R to boot into the Recovery System

Click the Utilities menu and select Terminal

Type csrutil disable and press return

Click the ? menu and select Restart

Once you have committed your changes, make sure to re-enable SIP! It does a lot to protect your system. (Same steps as above except type: csrutil enable)

I found this ans more pythonic:

if type(aObject) is str:
    #do your stuff here
    pass

since type objects are singleton, is can be used to do the compare the object to the str type

For Java 7+ doc you can use this:

BufferedReader reader = Files.newBufferedReader(path, StandardCharsets.UTF_8);

Here are all Charsets doc

For example if your file is in CP1252, use this method

Charset.forName("windows-1252");

Here is other canonical names for Java encodings both for IO and NIO doc

If you do not know with exactly encoding you have got in a file, you may use some third-party libs like this tool from Google this which works fairly neat.

Just to be clear, you are wanting to launch a program from a batch file and then have the batch file press keys (in your example, the arrow keys) within that launched program?

If that is the case, you aren't going to be able to do that with simply a ".bat" file as the launched would stop the batch file from continuing until it terminated--

My first recommendation would be to use something like AutoHotkey or AutoIt if possible, simply because they both have active forums where you'd find countless examples of people launching applications and sending key presses not to mention tools to simply "record" what you want to do. However you said this is a work computer and you may not be able to load a 3rd party program.. but you aren't without options.

You can use Windows Scripting Host from something like a .vbs file to launch a program and send keys to that process. If you're running a version of Windows that includes PowerShell 2.0 (Windows XP with Service Pack 3, Windows Vista with Service Pack 1, Windows 7, etc.) you can use Windows Scripting Host as a COM object from your PS script or use VB's Intereact class.

The specifics of how to do it are outside the scope of this answer but you can find numerous examples using the methods I just described by searching on SO or Google.

edit: Just to help you get started you can look here:

1. Automate tasks with Windows Script Host's SendKeys method
2. A useful thread about SendKeys

You need to run:

npx tsc

...rather than just calling tsc own its on like a Windows command as everyone else seems to be suggesting.

If you don't have npx installed then you should. It should be installed globally (unlike Typescript). So first run:

npm install -g npx

..then run npx tsc.

This is an example to read and write binary jjpg or wmv video file. FILE *fout; FILE *fin;

Int ch;
char *s;
fin=fopen("D:\\pic.jpg","rb");
if(fin==NULL)
     {  printf("\n Unable to open the file ");
         exit(1);
      }

 fout=fopen("D:\\ newpic.jpg","wb");
 ch=fgetc(fin);
       while (ch!=EOF)
             { 
                  s=(char *)ch;
                  printf("%c",s);
                 ch=fgetc (fin):
                 fputc(s,fout);
                 s++;
              }

        printf("data read and copied");
        fclose(fin);
        fclose(fout);

You should check your designer file. Open Form1.Designer.cs and
find this line: windows Form Designer Generated Code.
Expand this and you will see a lot of code. So check Whether this line is there inside datagridview1 controls if not place it.

this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick); 

I hope it helps.

For those, who wonder how it goes in VS.

MSVC 2015 Update 1, cl.exe version 19.00.24215.1:

#include <iostream>

template<typename X, typename Y>
struct A
{
  template<typename Z>
  static void f()
  {
    std::cout << "from A::f():" << std::endl
      << __FUNCTION__ << std::endl
      << __func__ << std::endl
      << __FUNCSIG__ << std::endl;
  }
};

void main()
{
  std::cout << "from main():" << std::endl
    << __FUNCTION__ << std::endl
    << __func__ << std::endl
    << __FUNCSIG__ << std::endl << std::endl;

  A<int, float>::f<bool>();
}

output:

from main():
main
main
int __cdecl main(void)

from A::f():
A<int,float>::f
f
void __cdecl A<int,float>::f<bool>(void)

Using of __PRETTY_FUNCTION__ triggers undeclared identifier error, as expected.

You can use _ _getitem__(key) function.

>>> iterable = ('A', 'B', 'C', 'D', 'E')
>>> key = 4
>>> iterable.__getitem__(key)
'E'

For my projects I made this solution (RecyclerView with setEmptyView method):

public class RecyclerViewEmptySupport extends RecyclerView {
    private View emptyView;

    private AdapterDataObserver emptyObserver = new AdapterDataObserver() {


        @Override
        public void onChanged() {
            Adapter<?> adapter =  getAdapter();
            if(adapter != null && emptyView != null) {
                if(adapter.getItemCount() == 0) {
                    emptyView.setVisibility(View.VISIBLE);
                    RecyclerViewEmptySupport.this.setVisibility(View.GONE);
                }
                else {
                    emptyView.setVisibility(View.GONE);
                    RecyclerViewEmptySupport.this.setVisibility(View.VISIBLE);
                }
            }

        }
    };

    public RecyclerViewEmptySupport(Context context) {
        super(context);
    }

    public RecyclerViewEmptySupport(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public RecyclerViewEmptySupport(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setAdapter(Adapter adapter) {
        super.setAdapter(adapter);

        if(adapter != null) {
            adapter.registerAdapterDataObserver(emptyObserver);
        }

        emptyObserver.onChanged();
    }

    public void setEmptyView(View emptyView) {
        this.emptyView = emptyView;
    }
}

And you should use it instead of RecyclerView class:

<com.maff.utils.RecyclerViewEmptySupport android:id="@+id/list1"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    />

<TextView android:id="@+id/list_empty"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Empty"
    />

and

RecyclerViewEmptySupport list = 
    (RecyclerViewEmptySupport)rootView.findViewById(R.id.list1);
list.setLayoutManager(new LinearLayoutManager(context));
list.setEmptyView(rootView.findViewById(R.id.list_empty));

Well; this works as well:

home = "$System.env.HOME"

It's not clear what you're aiming for.

I used the timezone-js package.

var timezoneJS  = require('timezone-js');
var tzdata = require('tzdata');

createDate(dateObj) {
    if ( dateObj == null ) {
        return null;
    }
    var nativeTimezoneOffset = new Date().getTimezoneOffset();
    var offset = this.getTimeZoneOffset();

    // use the native Date object if the timezone matches
    if ( offset == -1 * nativeTimezoneOffset ) {
        return dateObj;
    }

    this.loadTimeZones();

    // FIXME: it would be better if timezoneJS.Date was an instanceof of Date
    //        tried jquery $.extend
    //        added hack to Fiterpickr to look for Dater.getTime instead of "d instanceof Date"
    return new timezoneJS.Date(dateObj,this.getTimeZoneName());
},

Create this class:

public class StdOutErrLog {

private static final Logger logger = Logger.getLogger(StdOutErrLog.class);

public static void tieSystemOutAndErrToLog() {
    System.setOut(createLoggingProxy(System.out));
    System.setErr(createLoggingProxy(System.err));
}

public static PrintStream createLoggingProxy(final PrintStream realPrintStream) {
    return new PrintStream(realPrintStream) {
        public void print(final String string) {
            logger.info(string);
        }
        public void println(final String string) {
            logger.info(string);
        }
    };
}
}

Call this in your code

StdOutErrLog.tieSystemOutAndErrToLog();

Download Spring STS (SpringSource Tool Suite) and choose Spring Template Project from the Dashboard. This is the easiest way to get a preconfigured spring mvc project, ready to go.

methods for setting attributes(for example class) on an element: 1. el.className = string 2. el.setAttribute('class',string) 3. el.attributes.setNamedItem(object) 4. el.setAttributeNode(node)

I have made a simple benchmark test (here)

and it seems that setAttributeNode is about 3 times faster then using setAttribute.

so if performance is an issue - use "setAttributeNode"

If /foo/bar is on NFS (or possibly some FUSE filesystem), that might be the problem.

Either way, adding -O / --omit-dir-times to your command line will avoid it trying to set modification times on directories.

This is an inevitably long yet easy to follow explanation from ProGit book:

Note: For reference you can read Chapter 7.7 of the book, Reset Demystified

Git as a system manages and manipulates three trees in its normal operation:

• HEAD: Last commit snapshot, next parent
• Index: Proposed next commit snapshot
• Working Directory: Sandbox

The HEAD

HEAD is the pointer to the current branch reference, which is in turn a pointer to the last commit made on that branch. That means HEAD will be the parent of the next commit that is created. It’s generally simplest to think of HEAD as the snapshot of your last commit on that branch.

What does it contain?
To see what that snapshot looks like run the following in root directory of your repository:

                                 git ls-tree -r HEAD

it would result in something like this:

                       $ git ls-tree -r HEAD  
                       100644 blob a906cb2a4a904a152... README  
                       100644 blob 8f94139338f9404f2... Rakefile  
                       040000 tree 99f1a6d12cb4b6f19... lib  

The Index

Git populates this index with a list of all the file contents that were last checked out into your working directory and what they looked like when they were originally checked out. You then replace some of those files with new versions of them, and git commit converts that into the tree for a new commit.

What does it contain?
Use git ls-files -s to see what it looks like. You should see something like this:

                 100644 a906cb2a4a904a152e80877d4088654daad0c859 0 README   
                 100644 8f94139338f9404f26296befa88755fc2598c289 0 Rakefile  
                 100644 47c6340d6459e05787f644c2447d2595f5d3a54b 0 lib/simplegit.rb  

The Working Directory

This is where your files reside and where you can try changes out before committing them to your staging area (index) and then into history.

Visualized Sample

Let's see how do these three trees (As the ProGit book refers to them) work together?
Git’s typical workflow is to record snapshots of your project in successively better states, by manipulating these three trees. Take a look at this picture:

To get a good visualized understanding consider this scenario. Say you go into a new directory with a single file in it. Call this v1 of the file. It is indicated in blue. Running git init will create a Git repository with a HEAD reference which points to the unborn master branch

At this point, only the working directory tree has any content. Now we want to commit this file, so we use git add to take content in the working directory and copy it to the index.

Then we run git commit, which takes the contents of the index and saves it as a permanent snapshot, creates a commit object which points to that snapshot, and updates master to point to that commit.

If we run git status, we’ll see no changes, because all three trees are the same.

The beautiful point

git status shows the difference between these trees in the following manner:

• If the Working Tree is different from index, then git status will show there are some changes not staged for commit
• If the Working Tree is the same as index, but they are different from HEAD, then git status will show some files under changes to be committed section in its result
• If the Working Tree is different from the index, and index is different from HEAD, then git status will show some files under changes not staged for commit section and some other files under changes to be committed section in its result.

For the more curious

Note about git reset command
Hopefully, knowing how reset command works will further brighten the reason behind the existence of these three trees.

reset command is your Time Machine in git which can easily take you back in time and bring some old snapshots for you to work on. In this manner, HEAD is the wormhole through which you can travel in time. Let's see how it works with an example from the book:

Consider the following repository which has a single file and 3 commits which are shown in different colours and different version numbers:

The state of trees is like the next picture:

Step 1: Moving HEAD (--soft):

The first thing reset will do is move what HEAD points to. This isn’t the same as changing HEAD itself (which is what checkout does). reset moves the branch that HEAD is pointing to. This means if HEAD is set to the master branch, running git reset 9e5e6a4 will start by making master point to 9e5e6a4. If you call reset with --soft option it will stop here, without changing index and working directory. Our repo will look like this now:
Notice: HEAD~ is the parent of HEAD

Looking a second time at the image, we can see that the command essentially undid the last commit. As the working tree and the index are the same but different from HEAD, git status will now show changes in green ready to be committed.

Step 2: Updating the index (--mixed):

This is the default option of the command

Running reset with --mixed option updates the index with the contents of whatever snapshot HEAD points to currently, leaving Working Directory intact. Doing so, your repository will look like when you had done some work that is not staged and git status will show that as changes not staged for commit in red. This option will also undo the last commit and also unstage all the changes. It's like you made changes but have not called git add command yet. Our repo would look like this now:

Step 3: Updating the Working Directory (--hard)

If you call reset with --hard option it will copy contents of the snapshot HEAD is pointing to into HEAD, index and Working Directory. After executing reset --hard command, it would mean like you got back to a previous point in time and haven't done anything after that at all. see the picture below:

Conclusion

I hope now you have a better understanding of these trees and have a great idea of the power they bring to you by enabling you to change your files in your repository to undo or redo things you have done mistakenly.

Use -B, -A or -C option

grep --help
...
-B, --before-context=NUM  print NUM lines of leading context
-A, --after-context=NUM   print NUM lines of trailing context
-C, --context=NUM         print NUM lines of output context
-NUM                      same as --context=NUM
...

How can we open a new, but more importantly, how do we do stuff in that new tab?

Webdriver doesn't add a new WindowHandle for each tab, and only has control of the first tab. So, after selecting a new tab (Control + Tab Number) set .DefaultContent() on the driver to define the visible tab as the one you're going to do work on.

Visual Basic

Dim driver = New WebDriver("Firefox", BaseUrl)

' Open new tab - send Control T
Dim body As IWebElement = driver.FindElement(By.TagName("body"))
body.SendKeys(Keys.Control + "t")

' Go to a URL in that tab
driver.GoToUrl("YourURL")


' Assuming you have m tabs open, go to tab n by sending Control + n
body.SendKeys(Keys.Control + n.ToString())

' Now set the visible tab as the drivers default content.
driver.SwitchTo().DefaultContent()

Here are summarized the key differences between RESTful and RESTless web services:

1. Protocol

• RESTful services use REST architectural style,
• RESTless services use SOAP protocol.

2. Business logic / Functionality

• RESTful services use URL to expose business logic,
• RESTless services use the service interface to expose business logic.

3. Security

• RESTful inherits security from the underlying transport protocols,
• RESTless defines its own security layer, thus it is considered as more secure.

4. Data format

• RESTful supports various data formats such as HTML, JSON, text, etc,
• RESTless supports XML format.

5. Flexibility

• RESTful is easier and flexible,
• RESTless is not as easy and flexible.

6. Bandwidth

• RESTful services consume less bandwidth and resource,
• RESTless services consume more bandwidth and resources.

One of the challenges I had with the answers is that it assumed that the object was a single level. For example,

const testObj = { testKey: 'testValue' }
const refString = 'testKey';
const refObj = testObj[refString];

works fine, but

const testObj = { testKey:
                  { level2Key: 'level2Value' }
                }
const refString = 'testKey.level2Key';
const refObj = testObj[refString];

does not work.

What I ended up doing was building a function to access multi-level objects:

objVar(str) {
    let obj = this;
    const parts = str.split('.');
    for (let p of parts) {
        obj = obj[p];
    }
    return obj;
}

In the second scenario, then, I can pass the string to this function to get back the object I'm looking for:

const testObj = { testKey:
                  { level2Key: 'level2Value' }
                }
const refString = 'testObj.testKey.level2Key';
const refObj = objVar[refString];

The issue in the original question is that you are not capturing "page" event, to resolve this you need to add (page)='yourEventHandler($event)' as an attribute in the md-paginator tag.

check a working example here

You can also check the API docs here

This is what I ended up using a variation of, which checks for IE8 and below:

if (preg_match('/MSIE\s(?P<v>\d+)/i', @$_SERVER['HTTP_USER_AGENT'], $B) && $B['v'] <= 8) {
    // Browsers IE 8 and below
} else {
    // All other browsers
}

The above answers would give me Major version 6 on Windows 10.

The solution that I have found to work without adding extra VB libraries was following:

var versionString = (string)Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows NT\\CurrentVersion")?.GetValue("productName");

I wouldn't consider this the best way to get the version, but the upside this is oneliner no extra libraries, and in my case checking if it contains "10" was good enough.

If you just want go get to work real fast, and move along with your work...

Just export GIT_TERMINAL_PROMPT=1

$ export GIT_TERMINAL_PROMPT=1
$ go get [whatever]

It will now prompt you for a user/pass for the rest of your shell session. Put this in your .profile or setup git as above for a more permanent solution.

I've solved this problem by using the search function on Docker's website where '*' is a valid search that returns 200k repositories and then I crawled each invididual page. HTML parsing allows me to extract all the image names on each page.

You can use the onChange property. Something like:

<select onChange="window.location.href=this.value">
    <option value="www.google.com">A</option>
    <option value="www.aol.com">B</option>
</select>

Somewhere in your project, typically main.js or router.js

import Router from 'vue-router'

Router.prototype.open = function (routeObject) {
  const {href} = this.resolve(routeObject)
  window.open(href, '_blank')
}

In your component:

<div @click="$router.open({name: 'User', params: {ID: 123}})">Open in new tab</div>

Give an id to h3 like this:

<h3 id="headertag">Featured Offers</h3>

and in the javascript function do this :

document.getElementById("headertag").innerHTML = "Public Offers";

Right click properties, Application tab, then see the assembly name and default namespace

I like the viewer of Total Commander because it only loads the text you actually see and so is very fast. Of course, it is just a text/hex viewer, so it won't format your XML, but you can use a basic text search.

In my case this was happening because org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource is an autowired field without a Qualifier and I am using multiple datasources with qualified names. I solved this problem by using @Primary arbitrarily on one of my dataSource bean configurations like so

@Primary
@Bean(name="oneOfManyDataSources")
public DataSource dataSource() { ... }

I suppose they want you to implement AbstractRoutingDataSource, and then that auto configuration will just work because no qualifier is needed, you just have a single data source that allows your beans to resolve to the appropriate DataSource as needed. Then you don't need the @Primary or @Qualifier annotations at all, because you just have a single DataSource.

In any case, my solution worked because my beans specify DataSource by qualifier, and the JPA auto config stuff is happy because it has a single primary DataSource. I am by no means recommending this as the "right" way to do things, but in my case it solved the problem quickly and did not deter the behavior of my application in any noticeable manner. Will hopefully one day get around to implementing the AbstractRoutingDataSource and refactoring all the beans that need a specific DataSource and then perhaps that will be a neater solution.

If the width of the contents changes, you'll have to use this bit of code to update each column:

private void ResizeGridViewColumn(GridViewColumn column)
{
    if (double.IsNaN(column.Width))
    {
        column.Width = column.ActualWidth;
    }

    column.Width = double.NaN;
}

You'd have to fire it each time the data for that column updates.

you can multiplication using lambda

foo=[1,2,3,4]
bar=[1,2,5,55]
l=map(lambda x,y:x*y,foo,bar)

Try GetElementsByTagName method of XMLDocument class to read specific data or LoadXml method to read all data to xml document.

Well, here's an example for overloaded constructors.

public class Employee
{
   private String name;
   private int age;

   public Employee()
   {
      System.out.println("We are inside Employee() constructor");
   }

   public Employee(String name)
   {
      System.out.println("We are inside Employee(String name) constructor");
      this.name = name;
   }

   public Employee(String name, int age)
   {
      System.out.println("We are inside Employee(String name, int age) constructor");
      this.name = name;
      this.age = age;
   }

   public Employee(int age)
   {
      System.out.println("We are inside Employee(int age) constructor");
      this.age = age; 
   }

   public String getName()
   {
      return name;
   }

   public void setName(String name)
   {
      this.name = name;
   }

   public int getAge()
   {
      return age;
   }

   public void setAge(int age)
   {
      this.age = age;
   }
}

In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.

Here are some resources which throw more light on constructor overloading in java,

Adding to the accepted answer, you can used DATABASE_DEFAULT as encoding.

This allows database to make choice for you and your code becomes more portable.

SELECT MyColumn
FROM 
    FirstTable a
        INNER JOIN SecondTable b
            ON a.MyID COLLATE DATABASE_DEFAULT = b.YourID COLLATE DATABASE_DEFAULT

The line-continuation will fail if you have whitespace (spaces or tab characters[1]) after the backslash and before the newline. With no such whitespace, your example works fine for me:

$ cat test.sh
if ! fab --fabfile=.deploy/fabfile.py \
   --forward-agent \
   --disable-known-hosts deploy:$target; then
     echo failed
else
     echo succeeded
fi

$ alias fab=true; . ./test.sh
succeeded
$ alias fab=false; . ./test.sh
failed

Some detail promoted from the comments: the line-continuation backslash in the shell is not really a special case; it is simply an instance of the general rule that a backslash "quotes" the immediately-following character, preventing any special treatment it would normally be subject to. In this case, the next character is a newline, and the special treatment being prevented is terminating the command. Normally, a quoted character winds up included literally in the command; a backslashed newline is instead deleted entirely. But otherwise, the mechanism is the same. Most importantly, the backslash only quotes the immediately-following character; if that character is a space or tab, you just get a literal space or tab, and any subsequent newline remains unquoted.

[1] or carriage returns, for that matter, as Czechnology points out. Bash does not get along with Windows-formatted text files, not even in WSL. Or Cygwin, but at least their Bash port has added a set -o igncr option that you can set to make it carriage-return-tolerant.

Yes, the error you are getting means that there is not a private key on your Mac associated with the distribution certificate you are trying to use to sign the app.

There are two possible solutions, depending on whether the computer who requested the distribution certificate is available or not.

If the computer who requested the distribution certificate is available (or there is a backup of the distribution assets somewhere)

1. From the computer where the distribution asset was generated, open Xcode.
2. Click on Window, Organizer.
3. Expand the Teams section.
4. Select your team, select the certificate of "iOS Distribution" type, click Export and follow the instructions.
5. Save the exported file and go to your computer.
6. Repeat steps 1-3.
7. Click Import and select the file you exported before.

If the computer where the distribution profile was created is not accessible anymore (and there is not a backup)

You have to revoke the certificate and create a new one.

You may need to ask your team admin or agent to give you some privileges in order to generate distribution certificates. Once you have enough privileges, follow these steps (accurate as of 15-May-2013):

1. Go to this webpage: https://developer.apple.com/devcenter/ios/index.action
2. Click on "Member Center" and enter your iOS developer credentials.
3. Click on "Certificates, Identifiers & Profiles".
4. Click on "Certificates" under the "iOS Apps" section.
5. Expand the Certificates section on the left, select Distribution, and click on your distribution certificate.
6. Click Revoke and follow the instructions.
7. Click on the plus sign to add a new certificate.
8. Select "App Store and Ad Hoc" option, and click Continue.
9. Follow the steps printed in the webpage. That involves opening the Keychain application on your Mac and generate a Certificate Signing Request from there. Click Continue.
10. Upload the .csr file and click Continue.
11. A certificate is generated for distribution. Download it and double click it to integrate it in your keychain.

Reopen Xcode and check your project configuration to see if you can now select an "iPhone Distribution" certificate (i.e. it's not grayed out).

It isn't that tough to construct a mapping:

   1  2  3  4  5  use this mapping if (a,b) != (b,a)
1  0  1  3  6 10
2  2  4  7 11 16
3  5  8 12 17 23
4  9 13 18 24 31
5 14 19 25 32 40

   1  2  3  4  5 use this mapping if (a,b) == (b,a) (mirror)
1  0  1  2  4  6
2  1  3  5  7 10
3  2  5  8 11 14
4  4  8 11 15 19
5  6 10 14 19 24


    0  1 -1  2 -2 use this if you need negative/positive
 0  0  1  2  4  6
 1  1  3  5  7 10
-1  2  5  8 11 14
 2  4  8 11 15 19
-2  6 10 14 19 24

Figuring out how to get the value for an arbitrary a,b is a little more difficult.

This is the clearest, simplest way for me think of extends vs. super:

• extends is for reading

• super is for writing

I find "PECS" to be a non-obvious way to think of things regarding who is the "producer" and who is the "consumer". "PECS" is defined from the perspective of the data collection itself – the collection "consumes" if objects are being written to it (it is consuming objects from calling code), and it "produces" if objects are being read from it (it is producing objects to some calling code). This is counter to how everything else is named though. Standard Java APIs are named from the perspective of the calling code, not the collection itself. For example, a collection-centric view of java.util.List should have a method named "receive()" instead of "add()" – after all, the calling code adds the element, but the list itself receives the element.

I think it's more intuitive, natural and consistent to think of things from the perspective of the code that interacts with the collection – does the code "read from" or "write to" the collection? Following that, any code writing to the collection would be the "producer", and any code reading from the collection would be the "consumer".

For new you should use delete. For new[] use delete[]. Your second variant is correct.

Another option using Xpath.

library(RCurl)
library(XML)

theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
webpage <- getURL(theurl)
webpage <- readLines(tc <- textConnection(webpage)); close(tc)

pagetree <- htmlTreeParse(webpage, error=function(...){}, useInternalNodes = TRUE)

# Extract table header and contents
tablehead <- xpathSApply(pagetree, "//*/table[@class='wikitable sortable']/tr/th", xmlValue)
results <- xpathSApply(pagetree, "//*/table[@class='wikitable sortable']/tr/td", xmlValue)

# Convert character vector to dataframe
content <- as.data.frame(matrix(results, ncol = 8, byrow = TRUE))

# Clean up the results
content[,1] <- gsub(" ", "", content[,1])
tablehead <- gsub(" ", "", tablehead)
names(content) <- tablehead

Produces this result

None of these solutions quite worked for me. My original audio was being overwritten, or I was getting an error like "failed to map memory" with the more complex 'amerge' example. It seems I needed -filter_complex amix.

ffmpeg -i videowithaudioyouwanttokeep.mp4 -i audiotooverlay.mp3 -vcodec copy -filter_complex amix -map 0:v -map 0:a -map 1:a -shortest -b:a 144k out.mkv

A Linq one-liner for converting a byte array byteArrFilename read from a file to a pure ascii C-style zero-terminated string would be this: Handy for reading things like file index tables in old archive formats.

String filename = new String(byteArrFilename.TakeWhile(x => x != 0)
                              .Select(x => x < 128 ? (Char)x : '?').ToArray());

I use '?' as default char for anything not pure ascii here, but that can be changed, of course. If you want to be sure you can detect it, just use '\0' instead, since the TakeWhile at the start ensures that a string built this way cannot possibly contain '\0' values from the input source.

I built an extension called Checkpoints, an alternative to Local History. Checkpoints has support for viewing history for all files (that has checkpoints) in the tree view, not just the currently active file. There are some other minor differences aswell, but overall they are pretty similar.

Some practical uses for the [Serializable] attribute:

• Saving object state using binary serialisation; you can very easily 'save' entire object instances in your application to a file or network stream and then recreate them by deserialising - check out the BinaryFormatter class in System.Runtime.Serialization.Formatters.Binary
• Writing classes whose object instances can be stored on the clipboard using Clipboard.SetData() - nonserialisable classes cannot be placed on the clipboard.
• Writing classes which are compatible with .NET Remoting; generally, any class instance you pass between application domains (except those which extend from MarshalByRefObject) must be serialisable.

These are the most common usage cases that I have come across.

The Bash Reference Manual is an authoritative source of information about bash.

Here's an example of testing a variable to see if it exists:

if [ -z "$PS1" ]; then
        echo This shell is not interactive
else
        echo This shell is interactive
fi

(From section 6.3.2.)

Note that the whitespace after the open [ and before the ] is not optional.

Tips for Vim users

I had a script that had several declarations as follows:

export VARIABLE_NAME="$SOME_OTHER_VARIABLE/path-part"

But I wanted them to defer to any existing values. So I re-wrote them to look like this:

if [ -z "$VARIABLE_NAME" ]; then
        export VARIABLE_NAME="$SOME_OTHER_VARIABLE/path-part"
fi

I was able to automate this in vim using a quick regex:

s/\vexport ([A-Z_]+)\=("[^"]+")\n/if [ -z "$\1" ]; then\r  export \1=\2\rfi\r/gc

This can be applied by selecting the relevant lines visually, then typing :. The command bar pre-populates with :'<,'>. Paste the above command and hit enter.

I think you can use date() function to achive this

$date = '19:24:15 06/13/2013'; 
echo date('h:i:s a m/d/Y', strtotime($date));

This will output

07:24:15 pm 06/13/2013

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Updated

This is with DateTime

$date = new DateTime('19:24:15 06/13/2013');
echo $date->format('h:i:s a m/d/Y') ;

You didn't specified what JAXB-IMPL version are you using, but once I had the same problem (with jaxb-impl 2.0.5) and solved it using the annotation at the getter level instead of using it at the member level.

just write the css attributes in a proper manner i.e:

font-size:35px;

For flexibility and other places you might want to validated. You can use the following function.

`function validateOnlyTextField(element) {
    var str = element.value;
    if(!(/^[a-zA-Z, ]+$/.test(str))){
        // console.log('String contain number characters');
        str = str.substr(0,  str.length -1);
        element.value = str;
    }
}`

Then on your html section use the following event.

<input type="text" id="names" onkeyup="validateOnlyTextField(this)" />

You can always reuse the function.

For me, I had to use secure https rather than http.

I think you have a bug there, I code this way:

for (std::list<CAudioChannel *>::iterator itAudioChannel = audioChannels.begin();
             itAudioChannel != audioChannels.end(); )
{
    CAudioChannel *audioChannel = *itAudioChannel;
    std::list<CAudioChannel *>::iterator itCurrentAudioChannel = itAudioChannel;
    itAudioChannel++;

    if (audioChannel->destroyMe)
    {
        audioChannels.erase(itCurrentAudioChannel);
        delete audioChannel;
        continue;
    }
    audioChannel->Mix(outBuffer, numSamples);
}

Yes, set the cell as a RANGE object one time and then use that RANGE object in your code:

Sub RangeExample()
Dim MyRNG As Range

Set MyRNG = Sheets("Sheet1").Cells(23, 4)

Debug.Print MyRNG.Value

End Sub

Alternately you can simply store the value of that cell in memory and reference the actual value, if that's all you really need. That variable can be Long or Double or Single if numeric, or String:

Sub ValueExample()
Dim MyVal As String

MyVal = Sheets("Sheet1").Cells(23, 4).Value

Debug.Print MyVal

End Sub

We don't have any way to add volume in running container, but to achieve this objective you may use the below commands:

Copy files/folders between a container and the local filesystem:

docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH

docker cp [OPTIONS] SRC_PATH CONTAINER:DEST_PATH

For reference see:

https://docs.docker.com/engine/reference/commandline/cp/

The Short Answer

It looks like GitHub won't let you compare the branches because they don't actually share any of the same history at all, even though they may share much of the same files and code.

Here is a screenshot of the temporary fork I made of your repo, where I tried to compare master with the upstreambranch, like you described. Notice the error message:

It says:

There isn't anything to compare.

master and upstreambranch are entirely different commit histories.

The Long Answer

You probably downloaded the original source and added it to a completely new repo instead of cloning the original repo, right? Doing that will make it so that the history of your repo will be completely different from the history of the original repo, since your new repo won't have any of the same commits with the same sha IDs.

You can see that by doing a reverse log of your master branch and the upstreambranch:

# Your first commit, see commit sha
git log --reverse master
commit c548d7b1b16b0350d7fbdb3ff1cfedcb38051397 # <== HERE
Author: Padraic Stack <[email protected]>
Date:   Wed Apr 2 15:11:28 2014 +0100

    First commit of everything

# First commit sha of the original repo
git log --reverse upstreambranch
commit 105a12817234033c45b4dc7522ff3103f473a862 # <== THERE

Solutions

If you redo your commits on top of the original history, you should then be able to compare the branches. There are several different ways that you can redo your commits, including

git rebase --onto

and

git cherry-pick

You also can redo each commit manually, if you have to.

I found that running apache_start in gave me the exact error and on which line it was.

My error was that I left a space in between localhost: and the port.

Before the body of the constructor, use either:

: base (parameters)

: this (parameters)

Example:

public class People: User
{
   public People (int EmpID) : base (EmpID)
   {
      // Add more statements here.
   }
}

If you just want to tack something on by hand, then the sed answer will work for you. If instead the text is in file(s) (say file1.txt and file2.txt):

Using Perl:

perl -e 'open(OUT, ">>", "outfile.txt"); print OUT while (<>);' file*.txt

N.B. while the >> may look like an indication of redirection, it is just the file open mode, in this case "append".

An example of bootstrapping is in some web frameworks. You call index.php (the bootstrapper), and then it loads the frameworks helpers, models, configuration, and then loads the controller and passes off control to it.

As you can see, it's a simple file that starts a large process.

The meta-programming behind responder registration (see Parched Squid's answer) also allows you to do nifty stuff like this:

def index
  @posts = Post.all

  respond_to do |format|
    format.html  # index.html.erb
    format.json  { render :json => @posts }
    format.csv   { render :csv => @posts }
    format.js
  end
end

The csv line will cause to_csv to be called on each post when you visit /posts.csv. This makes it easy to export data as CSV (or any other format) from your rails site.

The js line will cause a javascript file /posts.js (or /posts.js.coffee) to be rendered/executed. I've found that to be a light-weight way to create an Ajax enabled site using jQuery UI pop-ups.

As of nginx 1.8.0, the correct solution is

sudo nginx -t && sudo service nginx reload

Note that due to a bug, configtest always returns a zero exit code even if the config file has an error.

Instead of modifying the height and width attributes of the image, try modifying the CSS height and width.

myimg = document.getElementById('myimg');
myimg.style.height = "50px";
myimg.style.width = "50px";

One common "gotcha" is that the height and width styles are strings that include a unit, like "px" in the example above.

Edit - I think that setting the height and width directly instead of using style.height and style.width should work. It would also have the advantage of already having the original dimensions. Can you post a bit of your code? Are you sure you're in standards mode instead of quirks mode?

This should work:

myimg = document.getElementById('myimg');
myimg.height = myimg.height * 2;
myimg.width = myimg.width * 2;

The Node Knockout competition wrapped up recently, and many of the submissions are available on github. The competition site doesn't appear to be working right now, but I'm sure you could Google up a few entries to check out.

CSV Files with Custom Delimiters

By default, a comma is used as a delimiter in a CSV file. However, some CSV files can use delimiters other than a comma. Few popular ones are | and \t.

import csv
data_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter='|')
    writer.writerows(data_list)

output:

SN|Name|Contribution
1|Linus Torvalds|Linux Kernel
2|Tim Berners-Lee|World Wide Web
3|Guido van Rossum|Python Programming

    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC, delimiter=';')
    writer.writerows(row_list)

As you can see, we have passed csv.QUOTE_NONNUMERIC to the quoting parameter. It is a constant defined by the csv module.

csv.QUOTE_NONNUMERIC specifies the writer object that quotes should be added around the non-numeric entries.

There are 3 other predefined constants you can pass to the quoting parameter:

• csv.QUOTE_ALL - Specifies the writer object to write CSV file with quotes around all the entries.
• csv.QUOTE_MINIMAL - Specifies the writer object to only quote those fields which contain special characters (delimiter, quotechar or any characters in lineterminator)
• csv.QUOTE_NONE - Specifies the writer object that none of the entries should be quoted. It is the default value.

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC,
                        delimiter=';', quotechar='*')
    writer.writerows(row_list)

output:

*SN*;*Name*;*Contribution*
1;*Linus Torvalds*;*Linux Kernel*
2;*Tim Berners-Lee*;*World Wide Web*
3;*Guido van Rossum*;*Python Programming*

Here, we can see that quotechar='*' parameter instructs the writer object to use * as quote for all non-numeric values.

An interface can extend multiple interfaces.

A class can implement multiple interfaces.

However, a class can only extend a single class.

Careful how you use the words extends and implements when talking about interface and class.

Add toString() method to your address class then do

System.out.println(Arrays.toString(houseAddress));

Start -> Control Panel -> Programs and Features, search for the Add-ons you would like to uninstall and click on particular one to uninstall.

Yes, I tried uninstalling from IE, Tools -> Manage Add-ons and then click "More Information" link at the bottom, however the "Remove" button was disabled. This didn't work.

Above mentioned solution for uninstalling from "Programs and Features" works.
