You can use:

Integer grandChildCount = ((BigInteger) result[1]).intValue();

Or perhaps cast to Number to cover both Integer and BigInteger values.

Instead of selecting all the columns in count count(*) you can limit count for one column count(UserName).

You can limit the whole search to one row by using Limit 0,1

SELECT COUNT(UserName)
  FROM TableName
 WHERE UserName = 'User' AND
       Password = 'Pass'
 LIMIT 0, 1

Unlike some browsers, Java follows the HTTPS specification strictly when it comes to the server identity verification (RFC 2818, Section 3.1) and IP addresses.

When using a host name, it's possible to fall back to the Common Name in the Subject DN of the server certificate, instead of using the Subject Alternative Name.

When using an IP address, there must be a Subject Alternative Name entry (of type IP address, not DNS name) in the certificate.

You'll find more details about the specification and how to generate such a certificate in this answer.

You need to create the project on GitHub first. After that go to the project directory and run in terminal:

git init
git remote add origin https://github.com/xxx/yyy.git
git add .
git commit -m "first commit"
git push -u origin master

I found it easier in following links:

In http://www.remondo.net/visitor-pattern-example-csharp/ I found an example that shows an mock example that shows what is benefit of visitor pattern. Here you have different container classes for Pill:

namespace DesignPatterns
{
    public class BlisterPack
    {
        // Pairs so x2
        public int TabletPairs { get; set; }
    }

    public class Bottle
    {
        // Unsigned
        public uint Items { get; set; }
    }

    public class Jar
    {
        // Signed
        public int Pieces { get; set; }
    }
}

As you see in above, You BilsterPack contain pairs of Pills' so you need to multiply number of pair's by 2. Also you may notice that Bottle use unit which is different datatype and need to be cast.

So in main method you may calculate pill count using following code:

foreach (var item in packageList)
{
    if (item.GetType() == typeof (BlisterPack))
    {
        pillCount += ((BlisterPack) item).TabletPairs * 2;
    }
    else if (item.GetType() == typeof (Bottle))
    {
        pillCount += (int) ((Bottle) item).Items;
    }
    else if (item.GetType() == typeof (Jar))
    {
        pillCount += ((Jar) item).Pieces;
    }
}

Notice that above code violate Single Responsibility Principle. That means you must change main method code if you add new type of container. Also making switch longer is bad practice.

So by introducing following code:

public class PillCountVisitor : IVisitor
{
    public int Count { get; private set; }

    #region IVisitor Members

    public void Visit(BlisterPack blisterPack)
    {
        Count += blisterPack.TabletPairs * 2;
    }

    public void Visit(Bottle bottle)
    {
        Count += (int)bottle.Items;
    }

    public void Visit(Jar jar)
    {
        Count += jar.Pieces;
    }

    #endregion
}

You moved responsibility of counting number of Pills to class called PillCountVisitor (And we removed switch case statement). That mean's whenever you need to add new type of pill container you should change only PillCountVisitor class. Also notice IVisitor interface is general for using in another scenarios.

By adding Accept method to pill container class:

public class BlisterPack : IAcceptor
{
    public int TabletPairs { get; set; }

    #region IAcceptor Members

    public void Accept(IVisitor visitor)
    {
        visitor.Visit(this);
    }

    #endregion
}

we allow visitor to visit pill container classes.

At the end we calculate pill count using following code:

var visitor = new PillCountVisitor();

foreach (IAcceptor item in packageList)
{
    item.Accept(visitor);
}

That mean's: Every pill container allow the PillCountVisitor visitor to see their pills count. He know how to count your pill's.

At the visitor.Count has the value of pills.

In http://butunclebob.com/ArticleS.UncleBob.IuseVisitor you see real scenario in which you can not use polymorphism (the answer) to follow Single Responsibility Principle. In fact in:

public class HourlyEmployee extends Employee {
  public String reportQtdHoursAndPay() {
    //generate the line for this hourly employee
  }
}

the reportQtdHoursAndPay method is for reporting and representation and this violate the Single Responsibility Principle. So it is better to use visitor pattern to overcome the problem.

I had simply changed the capitalization of ONE character in one of my report parameters and could no longer deploy. Changing the single character back to uppercase allowed me to redeploy. Remarkable.

timestamp ="124542124"
value = datetime.datetime.fromtimestamp(timestamp)
exct_time = value.strftime('%d %B %Y %H:%M:%S')

Get the readable date from timestamp with time also, also you can change the format of the date.

int remainder =0;

int division(int dividend, int divisor)
{
    int quotient = 1;

    int neg = 1;
    if ((dividend>0 &&divisor<0)||(dividend<0 && divisor>0))
        neg = -1;

    // Convert to positive
    unsigned int tempdividend = (dividend < 0) ? -dividend : dividend;
    unsigned int tempdivisor = (divisor < 0) ? -divisor : divisor;

    if (tempdivisor == tempdividend) {
        remainder = 0;
        return 1*neg;
    }
    else if (tempdividend < tempdivisor) {
        if (dividend < 0)
            remainder = tempdividend*neg;
        else
            remainder = tempdividend;
        return 0;
    }
    while (tempdivisor<<1 <= tempdividend)
    {
        tempdivisor = tempdivisor << 1;
        quotient = quotient << 1;
    }

    // Call division recursively
    if(dividend < 0)
        quotient = quotient*neg + division(-(tempdividend-tempdivisor), divisor);
    else
        quotient = quotient*neg + division(tempdividend-tempdivisor, divisor);
     return quotient;
 }


void main()
{
    int dividend,divisor;
    char ch = 's';
    while(ch != 'x')
    {
        printf ("\nEnter the Dividend: ");
        scanf("%d", &dividend);
        printf("\nEnter the Divisor: ");
        scanf("%d", &divisor);

        printf("\n%d / %d: quotient = %d", dividend, divisor, division(dividend, divisor));
        printf("\n%d / %d: remainder = %d", dividend, divisor, remainder);

        _getch();
    }
}

This way work for me in Swift 2 iOS 8.x:

PS (this method dont require to override orientation functions like shouldautorotate on every viewController, just one method on AppDelegate)

Check the "requires full screen" in you project general info.

So, on AppDelegate.swift make a variable:

var enableAllOrientation = false

So, put also this func:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
        if (enableAllOrientation == true){
            return UIInterfaceOrientationMask.All
        }
        return UIInterfaceOrientationMask.Portrait
}

So, in every class in your project you can set this var in viewWillAppear:

override func viewWillAppear(animated: Bool)
{
        super.viewWillAppear(animated)
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        appDelegate.enableAllOrientation = true
}

If you need to make a choices based on the device type you can do this:

override func viewWillAppear(animated: Bool)
    {
        super.viewWillAppear(animated)
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        switch UIDevice.currentDevice().userInterfaceIdiom {
        case .Phone:
        // It's an iPhone
           print(" - Only portrait mode to iPhone")
           appDelegate.enableAllOrientation = false
        case .Pad:
        // It's an iPad
           print(" - All orientation mode enabled on iPad")
           appDelegate.enableAllOrientation = true
        case .Unspecified:
        // Uh, oh! What could it be?
           appDelegate.enableAllOrientation = false
        }
    }

Try:

$counter = 0;
foreach ($Contents as $item) {
          something 
          your code  ...
      $counter++;      
}
$total_count=$counter-1;

I had the same problem a few weeks ago like yours; but I invented a brilliant solution for exchanging variables between PHP and JavaScript. It worked for me well:

1. Create a hidden form on a HTML page

2. Create a Textbox or Textarea in that hidden form

3. After all of your code written in the script, store the final value of your variable in that textbox

4. Use $_REQUEST['textbox name'] line in your PHP to gain access to value of your JavaScript variable.

I hope this trick works for you.

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

If you want it in crlf (Windows Eol), go to File -> Preferences -> Settings. Type "end of line" in the User tab and make sure Files: Eol is set to \r\n and if you're using the Prettier extension, make sure Prettier: End of Line is set to crlf. Finally, on your eslintrc file, add this rule: 'linebreak-style': ['error', 'windows']

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

If you use file_put_contents you don't need to do a fopen -> fwrite -> fclose, the file_put_contents does all that for you. You should also check if the webserver has write rights in the directory where you are trying to write your "data.txt" file.

Depending on your PHP version (if it's old) you might not have the file_get/put_contents functions. Check your webserver log to see if any error appeared when you executed the script.

The easier is add [0] - select first value of list with one element:

dfb = df[df['A']==5].index.values.astype(int)[0]
dfbb = df[df['A']==8].index.values.astype(int)[0]

dfb = int(df[df['A']==5].index[0])
dfbb = int(df[df['A']==8].index[0])

But if possible some values not match, error is raised, because first value not exist.

Solution is use next with iter for get default parameetr if values not matched:

dfb = next(iter(df[df['A']==5].index), 'no match')
print (dfb)
4

dfb = next(iter(df[df['A']==50].index), 'no match')
print (dfb)
no match

Then it seems need substract 1:

print (df.loc[dfb:dfbb-1,'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

Another solution with boolean indexing or query:

print (df[(df['A'] >= 5) & (df['A'] < 8)])
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

print (df.loc[(df['A'] >= 5) & (df['A'] < 8), 'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

print (df.query('A >= 5 and A < 8'))
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

Data can be pulled into an excel from another excel through Workbook method or External reference or through Data Import facility.

If you want to read or even if you want to update another excel workbook, these methods can be used. We may not depend only on VBA for this.

If you switch to the jQuery UI Dialog box, you can initialize the buttons array with the appropriate names like:

$("#id").dialog({
  buttons: {
    "Yes": function() {},
    "No": function() {}
  }
});

Okay, but you all know that the * is a wildcard and allows cross site scripting from every domain?

You would like to send multiple Access-Control-Allow-Origin headers for every site that's allowed to - but unfortunately its officially not supported to send multiple Access-Control-Allow-Origin headers, or to put in multiple origins.

You can solve this by checking the origin, and sending back that one in the header, if it is allowed:

$origin = $_SERVER['HTTP_ORIGIN'];
$allowed_domains = [
    'http://mysite1.com',
    'https://www.mysite2.com',
    'http://www.mysite2.com',
];

if (in_array($origin, $allowed_domains)) {
    header('Access-Control-Allow-Origin: ' . $origin);
}

Thats much safer. You might want to edit the matching and change it to a manual function with some regex, or something like that. At least this will only send back 1 header, and you will be sure its the one that the request came from. Please do note that all HTTP headers can be spoofed, but this header is for the client's protection. Don't protect your own data with those values. If you want to know more, read up a bit on CORS and CSRF.

Why is it safer?

Allowing access from other locations then your own trusted site allows for session highjacking. I'm going to go with a little example - image Facebook allows a wildcard origin - this means that you can make your own website somewhere, and make it fire AJAX calls (or open iframes) to facebook. This means you can grab the logged in info of the facebook of a visitor of your website. Even worse - you can script POST requests and post data on someone's facebook - just while they are browsing your website.

Be very cautious when using the ACAO headers!

This will work

<div style="width:800px;">
  <div style="width:300px; float:left;"></div>
  <div style="width:300px; float:right;"></div>

<div style="clear: both;"></div>

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

Not a full answer but perhaps a useful hint. If it is really the first item you want*, then

next(iter(q))

is much faster than

list(q)[0]

for large dicts, since the whole thing doesn't have to be stored in memory.

For 10.000.000 items I found it to be almost 40.000 times faster.

*The first item in case of a dict being just a pseudo-random item before Python 3.6 (after that it's ordered in the standard implementation, although it's not advised to rely on it).

To trim a string down so it does not contain two or more spaces in a row. Every instance of 2 or more space will be trimmed down to 1 space. A simple solution:

While ImageText1.Contains("  ")                     '2 spaces.
    ImageText1 = ImageText1.Replace("  ", " ")      'Replace with 1 space.
End While

The meta cache control tag allows Web publishers to define how pages should be handled by caches. They include directives to declare what should be cacheable, what may be stored by caches, modifications of the expiration mechanism, and revalidation and reload controls.

The allowed values are:

Public - may be cached in public shared caches
Private - may only be cached in private cache
no-Cache - may not be cached
no-Store - may be cached but not archived

Please be careful about case sensitivity. Add the following meta tag in the source of your webpage. The difference in spelling at the end of the tag is either you use " /> = xml or "> = html.

    <meta http-equiv="Cache-control" content="public">
    <meta http-equiv="Cache-control" content="private">
    <meta http-equiv="Cache-control" content="no-cache">
    <meta http-equiv="Cache-control" content="no-store">

For the best way to do that, try it.

First, find the commit id of the commit that deleted your file. It will give you a summary of commits which deleted files.

git log --diff-filter=D --summary

git checkout 84sdhfddbdddf~1

Note: 84sdhfddbddd is your commit id

Through this you can easily recover all deleted files.

I adapted the answer by ChrisB. Like in his example a temporary combobox is made visible when a cell is clicked. Additionally:

1. List of Combobox items is updated as user types, only matching items are displayed
2. if any item from combobox is selected, filtering is skipped as it makes sense and because of this error

Notes:

1. ComboBoxe's MatchEntry must be set to 2 - fmMatchEntryNone. Don't forget to set ComboBox name to TempCombo
2. I am using listFillRange to set ComboBox options. The range must be continuous, so, matching items are stored in a help column.
3. I have tried accomplishing the same with ComboBox.addItem, but it turned out to be hard to repaint list box as user types

For encoding to base64 in Angular2, you can use btoa() function.

Example:-

console.log(btoa("stringAngular2")); 
// Output:- c3RyaW5nQW5ndWxhcjI=

For decoding from base64 in Angular2, you can use atob() function.

Example:-

console.log(atob("c3RyaW5nQW5ndWxhcjI=")); 
// Output:- stringAngular2

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName
Set
Created="01/01/2000"
where Created is NULL

Documented couple of design issues with this in a comment above. Short story, in Oracle, you need to limit the results manually when you have large tables and/or tables with same column names (and you don't want to explicit type them all out and rename them all). Easy solution is to figure out your breakpoint and limit that in your query. Or you could also do this in the inner query if you don't have the conflicting column names constraint. E.g.

WHERE m_api_log.created_date BETWEEN TO_DATE('10/23/2015 05:00', 'MM/DD/YYYY HH24:MI') 
                                 AND TO_DATE('10/30/2015 23:59', 'MM/DD/YYYY HH24:MI')  

will cut down the results substantially. Then you can ORDER BY or even do the outer query to limit rows.

Also, I think TOAD has a feature to limit rows; but, not sure that does limiting within the actual query on Oracle. Not sure.

You will also need to set 100% height on the html element:

html { height:100%; }

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

For one, you can wrap it up in a function:

function manytimes {
    n=0
    times=$1
    shift
    while [[ $n -lt $times ]]; do
        $@
        n=$((n+1))
    done
}

Call it like:

$ manytimes 3 echo "test" | tr 'e' 'E'
tEst
tEst
tEst

Using BS4 for this specific task seems overkill.

Try instead:

website = urllib2.urlopen('http://10.123.123.5/foo_images/Repo/')
html = website.read()
files = re.findall('href="(.*tgz|.*tar.gz)"', html)
print sorted(x for x in (files))

I found this nifty piece of code on http://www.pythonforbeginners.com/code/regular-expression-re-findall and works for me quite well.

I tested it only on my scenario of extracting a list of files from a web folder that exposes the files\folder in it, e.g.:

and I got a sorted list of the files\folders under the URL

They are not null if you don't initialize the struct.

Snapshot s; // receives no initialization
Snapshot s = {}; // value initializes all members

The second will make all members zero, the first leaves them at unspecified values. Note that it is recursive:

struct Parent { Snapshot s; };
Parent p; // receives no initialization
Parent p = {}; // value initializes all members

The second will make p.s.{x,y} zero. You cannot use these aggregate initializer lists if you've got constructors in your struct. If that is the case, you will have to add proper initalization to those constructors

struct Snapshot {
    int x;
    double y;
    Snapshot():x(0),y(0) { }
    // other ctors / functions...
};

Will initialize both x and y to 0. Note that you can use x(), y() to initialize them disregarding of their type: That's then value initialization, and usually yields a proper initial value (0 for int, 0.0 for double, calling the default constructor for user defined types that have user declared constructors, ...). This is important especially if your struct is a template.

Zeep is a decent SOAP library for Python that matches what you're asking for: http://docs.python-zeep.org

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

This is a bit of a work around, but one way you can achieve this is by adding a breakpoint at the start of the javascript file or block you want to manipulate.

Then when you reload, the debugger will pause on that breakpoint, and you can make any changes you want to the source, save the file and then run the debugger through the modified code.

But as everyone has said, next reload the changes will be gone - at least it let's you run some slightly modified JS client side.

Quite an old question, but might be helpful to somebody in need.

If you know the url, 1. open the chrome browser, 2. open developer tools in chrome , 3. Put the url in search bar and hit enter 4. look in network tab, you will see the ip and port both

Overloading is defining functions that have similar signatures, yet have different parameters. Overriding is only pertinent to derived classes, where the parent class has defined a method and the derived class wishes to override that method.

In PHP, you can only overload methods using the magic method __call.

An example of overriding:

<?php

class Foo {
   function myFoo() {
      return "Foo";
   }
}

class Bar extends Foo {
   function myFoo() {
      return "Bar";
   }
}

$foo = new Foo;
$bar = new Bar;
echo($foo->myFoo()); //"Foo"
echo($bar->myFoo()); //"Bar"
?>

Another method is to use netcat (or nc, dependent upon which posix) in the same format as vatine shows or you can create a text file that contains each command on it's own line.

I have found that some posix' telnets do not handle redirect correctly (which is why I suggest netcat)

You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]

This is pretty simple with numpy, just subtract the arrays:

diffs = array1 - array2

I get:

diffs == array([ 0.1,  0.2,  0.3])

Have you configured the virtual directory as an ASP.NET application for the right framework version?

See IIS Setup

No, don't spoil it with a break. This is the last remaining stronghold for the use of goto.

I would use ConfigurationManager.OpenMappedExeConfiguration.

    compileSdkVersion 23
    buildToolsVersion '23.0.1'

defaultConfig {
    applicationId ""

    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.android.support:recyclerview-v7:23.0.0'
compile 'com.android.support:appcompat-v7:23.0.1'
}

Try this it may help you:

public void ButtonClick(View view) {
    Fragment mFragment = new YourNextFragment(); 
    getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, mFragment).commit();
}

I wanted to add one more point is, if you are storing a really large number like 902054990011312 then one can easily see the difference of INT(20) and BIGINT(20). It is advisable to store in BIGINT.

First the mysqldump command is executed and the output generated is redirected using the pipe. The pipe is sending the standard output into the gzip command as standard input. Following the filename.gz, is the output redirection operator (>) which is going to continue redirecting the data until the last filename, which is where the data will be saved.

For example, this command will dump the database and run it through gzip and the data will finally land in three.gz

mysqldump -u user -pupasswd my-database | gzip > one.gz > two.gz > three.gz

$> ls -l
-rw-r--r--  1 uname  grp     0 Mar  9 00:37 one.gz
-rw-r--r--  1 uname  grp  1246 Mar  9 00:37 three.gz
-rw-r--r--  1 uname  grp     0 Mar  9 00:37 two.gz

My original answer is an example of redirecting the database dump to many compressed files (without double compressing). (Since I scanned the question and seriously missed - sorry about that)

This is an example of recompressing files:

mysqldump -u user -pupasswd my-database | gzip -c > one.gz; gzip -c one.gz > two.gz; gzip -c two.gz > three.gz

$> ls -l
-rw-r--r--  1 uname  grp  1246 Mar  9 00:44 one.gz
-rw-r--r--  1 uname  grp  1306 Mar  9 00:44 three.gz
-rw-r--r--  1 uname  grp  1276 Mar  9 00:44 two.gz

This is a good resource explaining I/O redirection: http://www.codecoffee.com/tipsforlinux/articles2/042.html

If you are on Eclipse,

Right click on your project folder under "Package Explorer".

Goto Source -> Clean up and choose your project.

This will cleanup any mess and your break-point should work now.

If you need to do this as part of a script then the best way is to use Java. Assuming the bin directory is in your path (in most cases), you can use the command line:

jar xf test.zip

If Java is not on your path, reference it directly:

C:\Java\jdk1.6.0_03\bin>jar xf test.zip

Haven't seen this solution yet so here's how I did it without using read_csv:

df.rename(columns={'A':'','B':''})

If you rename all your column names to empty strings your table will return without a header.

And if you have a lot of columns in your table you can just create a dictionary first instead of renaming manually:

df_dict = dict.fromkeys(df.columns, '')
df.rename(columns = df_dict)

To extrapolate on Felix Kling's comment, you can use .filter() like this:

var sources = images.map(function (img) {
  if(img.src.split('.').pop() === "json") { // if extension is .json
    return null; // skip
  } else {
    return img.src;
  }
}).filter(Boolean);

That will remove falsey values from the array that is returned by .map()

You could simplify it further like this:

var sources = images.map(function (img) {
  if(img.src.split('.').pop() !== "json") { // if extension is .json
    return img.src;
  }
}).filter(Boolean);

Or even as a one-liner using an arrow function, object destructuring and the && operator:

var sources = images.map(({ src }) => src.split('.').pop() !== "json" && src).filter(Boolean);

Using bootstrap with a little bit of customization, the following seems to work for me:

I need 3 partitions in my container and I tried this:

CSS:

.row.content {height: 100%; width:100%; position: fixed; }
.sidenav {
  padding-top: 20px;
  border: 1px solid #cecece;
  height: 100%;
}
.midnav {
  padding: 0px;
}

HTML:

  <div class="container-fluid text-center"> 
    <div class="row content">
    <div class="col-md-2 sidenav text-left">Some content 1</div>
    <div class="col-md-9 midnav text-left">Some content 2</div>
    <div class="col-md-1 sidenav text-center">Some content 3</div>
    </div>
  </div>

So i tried the above :javascript which works :) However HAML wraps the generated code in CDATA like so:

<script type="text/javascript">
  //<![CDATA[
    $(document).ready( function() {
       $('body').addClass( 'test' );
    } );
  //]]>
</script>

The following HAML will generate the typical tag for including (for example) typekit or google analytics code.

 %script{:type=>"text/javascript"}
  //your code goes here - dont forget the indent!

<img src="../template/edit.png" name="edit-save" onclick="this.src = '../template/save.png'" />

Arrays in PHP are associative arrays (otherwise known as dictionaries or hashes) by default. If you don't explicitly assign a key to a value, the interpreter will silently do that for you. So, the expression you've got up there iterates through $user_list, making the key available as $user and the value available as $pass as local variables in the body of the foreach.

>>> a='2010-01-31'
>>> a.split('-')
['2010', '01', '31']
>>> year,month,date=a.split('-')
>>> year
'2010'
>>> month
'01'
>>> date
'31'

Bitmap implements Parcelable, so you could always pass it with the intent:

Intent intent = new Intent(this, NewActivity.class);
intent.putExtra("BitmapImage", bitmap);

and retrieve it on the other end:

Intent intent = getIntent(); 
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("BitmapImage");

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

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

So, you can do this:

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

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

The code to make it work in IEs from Webreflection:

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

This is what I ended up using to take the value from an input, expanding numbers less than 17digits and converting Exponential numbers to x10^y

// e.g.
//  niceNumber("1.24e+4")   becomes 
// 1.24x10 to the power of 4 [displayed in Superscript]

function niceNumber(num) {
  try{
        var sOut = num.toString();
      if ( sOut.length >=17 || sOut.indexOf("e") > 0){
      sOut=parseFloat(num).toPrecision(5)+"";
      sOut = sOut.replace("e","x10<sup>")+"</sup>";
      }
      return sOut;

  }
  catch ( e) {
      return num;
  }
}

A minor modification like below worked for me when using it from within perl and system() call:

sftp {user}@{host} <<< $'put {local_file_path} {remote_file_path}'

I posted a similar question about checking if byte[] is full of zeroes. (SIMD code was beaten so I removed it from this answer.) Here is fastest code from my comparisons:

static unsafe bool EqualBytesLongUnrolled (byte[] data1, byte[] data2)
{
    if (data1 == data2)
        return true;
    if (data1.Length != data2.Length)
        return false;

    fixed (byte* bytes1 = data1, bytes2 = data2) {
        int len = data1.Length;
        int rem = len % (sizeof(long) * 16);
        long* b1 = (long*)bytes1;
        long* b2 = (long*)bytes2;
        long* e1 = (long*)(bytes1 + len - rem);

        while (b1 < e1) {
            if (*(b1) != *(b2) || *(b1 + 1) != *(b2 + 1) || 
                *(b1 + 2) != *(b2 + 2) || *(b1 + 3) != *(b2 + 3) ||
                *(b1 + 4) != *(b2 + 4) || *(b1 + 5) != *(b2 + 5) || 
                *(b1 + 6) != *(b2 + 6) || *(b1 + 7) != *(b2 + 7) ||
                *(b1 + 8) != *(b2 + 8) || *(b1 + 9) != *(b2 + 9) || 
                *(b1 + 10) != *(b2 + 10) || *(b1 + 11) != *(b2 + 11) ||
                *(b1 + 12) != *(b2 + 12) || *(b1 + 13) != *(b2 + 13) || 
                *(b1 + 14) != *(b2 + 14) || *(b1 + 15) != *(b2 + 15))
                return false;
            b1 += 16;
            b2 += 16;
        }

        for (int i = 0; i < rem; i++)
            if (data1 [len - 1 - i] != data2 [len - 1 - i])
                return false;

        return true;
    }
}

If you are still recieving the InvalidKeyException when running my AES encryption program with 256 bit keys, but not with 128 bit keys, it is because you have not installed the new policy JAR files correctly, and has nothing to do with BouncyCastle (which is also restrained by those policy files). Try uninstalling, then re-installing java and then replaceing the old jar's with the new unlimited strength ones. Other than that, I'm out of ideas, best of luck.

You can see the policy files themselves if you open up the lib/security/local_policy.jar and US_export_policy.jar files in winzip and look at the conatined *.policy files in notepad and make sure they look like this:

default_local.policy:

    // Country-specific policy file for countries with no limits on crypto strength.
grant {
    // There is no restriction to any algorithms.
    permission javax.crypto.CryptoAllPermission; 
};

default_US_export.policy:

// Manufacturing policy file.
grant {
    // There is no restriction to any algorithms.
    permission javax.crypto.CryptoAllPermission; 
};

For each row returned by a query, the ROWNUM pseudocolumn returns a number indicating the order in which Oracle selects the row from a table or set of joined rows. The first row selected has a ROWNUM of 1, the second has 2, and so on.

  SELECT * FROM sometable1 so
    WHERE so.id IN (
    SELECT so2.id from sometable2 so2
    WHERE ROWNUM <=5
    )
    AND ORDER BY so.somefield AND ROWNUM <= 100 

I have implemented this in oracle server 11.2.0.1.0

QLineEdit::setValidator(), for example:

myLineEdit->setValidator( new QIntValidator(0, 100, this) );

or

myLineEdit->setValidator( new QDoubleValidator(0, 100, 2, this) );

See: QIntValidator, QDoubleValidator, QLineEdit::setValidator

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

Getting rid of Integrated Security=true worked for me.

If you don't like public static initializer, reflection can be a workaround.

<?php

class LanguageUtility
{
    public static function initializeClass($class)
    {
        try
        {
            // Get a static method named 'initialize'. If not found,
            // ReflectionMethod() will throw a ReflectionException.
            $ref = new \ReflectionMethod($class, 'initialize');

            // The 'initialize' method is probably 'private'.
            // Make it accessible before calling 'invoke'.
            // Note that 'setAccessible' is not available
            // before PHP version 5.3.2.
            $ref->setAccessible(true);

            // Execute the 'initialize' method.
            $ref->invoke(null);
        }   
        catch (Exception $e)
        {
        }
    }
}

class MyClass
{
    private static function initialize()
    {
    }
}

LanguageUtility::initializeClass('MyClass');

?>

addClass=(selector,classes)=>document.querySelector(selector).classList(...classes.split(' '));

This will add ONE class or MULTIPLE classes :

addClass('#myDiv','back-red'); // => Add "back-red" class to <div id="myDiv"/>
addClass('#myDiv','fa fa-car') //=>Add two classes to "div"

The short answer: when you create a ListView you pass it a reference to the data. Now, whenever this data will be altered, it will affect the list view and thus add the item to it, after you'll call adapter.notifyDataSetChanged();.

If you're using a RecyclerView, update only the last element (if you've added it at the end of the list of objs) to save memory with: mAdapter.notifyItemInserted(mItems.size() - 1);

The way i did in Android Studio which is also based on IntelliJ was like this. In commit dialog, I reverted the change for workspace.xml, then it was moved to unversioned file. After that I deleted this from commit dialog. Now it won't appear in the changelist. Note that my gitignore was already including .idea/workspace.xml

If you get a model instance from the database, then calling the save method will always update that instance. For example:

t = TemperatureData.objects.get(id=1)
t.value = 999  # change field
t.save() # this will update only

If your goal is prevent any INSERTs, then you can override the save method, test if the primary key exists and raise an exception. See the following for more detail:

• How Django knows to UPDATE vs. INSERT

Here is how you can read the entire file contents, and if done successfully, start a webserver which displays the JPG image in response to every request:

var http = require('http')
var fs = require('fs')

fs.readFile('image.jpg', function(err, data) {
  if (err) throw err // Fail if the file can't be read.
  http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'image/jpeg'})
    res.end(data) // Send the file data to the browser.
  }).listen(8124)
  console.log('Server running at http://localhost:8124/')
})

Note that the server is launched by the "readFile" callback function and the response header has Content-Type: image/jpeg.

[Edit] You could even embed the image in an HTML page directly by using an <img> with a data URI source. For example:

  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><img src="data:image/jpeg;base64,')
  res.write(Buffer.from(data).toString('base64'));
  res.end('"/></body></html>');

As mentioned by ecdpalma below, git 1.7.12+ (August 2012) has enhanced the option --root for git rebase:

"git rebase [-i] --root $tip" can now be used to rewrite all the history leading to "$tip" down to the root commit.

That new behavior was initially discussed here:

I personally think "git rebase -i --root" should be made to just work without requiring "--onto" and let you "edit" even the first one in the history.
It is understandable that nobody bothered, as people are a lot less often rewriting near the very beginning of the history than otherwise.

The patch followed.

(original answer, February 2010)

As mentioned in the Git FAQ (and this SO question), the idea is:

1. Create new temporary branch
2. Rewind it to the commit you want to change using git reset --hard
3. Change that commit (it would be top of current HEAD, and you can modify the content of any file)

4. Rebase branch on top of changed commit, using:

   git rebase --onto <tmp branch> <commit after changed> <branch>`
   

The trick is to be sure the information you want to remove is not reintroduced by a later commit somewhere else in your file. If you suspect that, then you have to use filter-branch --tree-filter to make sure the content of that file does not contain in any commit the sensible information.

In both cases, you end up rewriting the SHA1 of every commit, so be careful if you have already published the branch you are modifying the contents of. You probably shouldn’t do it unless your project isn’t yet public and other people haven’t based work off the commits you’re about to rewrite.

For git 1.9.5 on Windows 7: "my Notes" (double quotes) corrected this issue. In my case putting the file(s) before or after the -m 'message'. made no difference; using single quotes was the problem.

My problem was because I added a second parameter:

AngularFireModule.initializeApp(firebaseConfig, 'reservas')

if I remove the second parameter it works fine:

AngularFireModule.initializeApp(firebaseConfig)

Maybe a much simpler way? Just adding to the list of answers here:

@for /f "tokens=1,* delims=: " %%a in ('sc queryex state=Inactive') do net start "%%b"

You need to double check the PATH environment setting. C:\Program Files\Java\jdk-13 you currently have there is not correct. Please make sure you have the bin subdirectory for the latest JDK version at the top of the PATH list.

java.exe executable is in C:\Program Files\Java\jdk-13\bin directory, so that is what you need to have in PATH.

Use this tool to quickly verify or edit the environment variables on Windows. It allows to reorder PATH entries. It will also highlight invalid paths in red.

If you want your code to run on lower JDK versions as well, change the target bytecode version in the IDE. See this answer for the relevant screenshots.

See also this answer for the Java class file versions. What happens is that you build the code with Java 13 and 13 language level bytecode (target) and try to run it with Java 8 which is the first (default) Java version according to the PATH variable configuration.

The solution is to have Java 13 bin directory in PATH above or instead of Java 8. On Windows you may have C:\Program Files (x86)\Common Files\Oracle\Java\javapath added to PATH automatically which points to Java 8 now:

If it's the case, remove the highlighted part from PATH and then logout/login or reboot for the changes to have effect. You need to Restart as administrator first to be able to edit the System variables (see the button on the top right of the system variables column).

Getting this error when doing a cordova build android --release

I was able to resolve this, after trying so so many different things, by simply doing :

npm install cordova -g   # to upgrade to version 10.0.0

cordova platform rm android
cordova platform add android    # to upgrade to android version 9.0.0

In your example, because you use CurrentDB to execute your INSERT you've made it harder for yourself. Instead, this will work:

  Dim query As String
  Dim newRow As Long  ' note change of data type
  Dim db As DAO.Database

  query = "INSERT INTO InvoiceNumbers (date) VALUES (" & NOW() & ");"
  Set db = CurrentDB
  db.Execute(query)
  newRow = db.OpenRecordset("SELECT @@IDENTITY")(0)
  Set db = Nothing

I used to do INSERTs by opening an AddOnly recordset and picking up the ID from there, but this here is a lot more efficient. And note that it doesn't require ADO.

Use HttpServerUtility.UrlEncode

As Alex says, it works very well. The only tricky part is to remember to make any changes in the cmake files, rather than from within Visual Studio. So on all platforms, the workflow is similar to if you'd used plain old makefiles.

But it's fairly easy to work with, and I've had no issues with cmake generating invalid files or anything like that, so I wouldn't worry too much.

For people who are reading byte array into String and trying to convert to object with JAXB, you can add "iso-8859-1" encoding by creating String from byte array like this:

String JAXBallowedString= new String(byte[] input, "iso-8859-1");

This would replace the conflicting byte to single-byte encoding which JAXB can handle. Obviously this solution is only to parse the xml.

Found out what was wrong. I never installed the setuptools for python, so it was missing some vital files, like the egg ones.

If you find yourself having my issue above, download this file and then in powershell or command prompt, navigate to ez_setup’s directory and execute the command and this will run the file for you:

$ [sudo] python ez_setup.py

If you still need to install pip at this point, run:

$ [sudo] easy_install pip

easy_install was part of the setuptools, and therefore wouldn't work for installing pip.

Then, pip will successfully install django with the command:

$ [sudo] pip install django

Hope I saved someone the headache I gave myself!

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.

What you could do is copy the code from tkinter.py into a file called mytkinter.py, then do this code:

import tkinter, mytkinter
root = tkinter.Tk()
window = mytkinter.Tk()
button = mytkinter.Button(window, text="Search", width = 7,
                               command=cmd)
button2 = tkinter.Button(root, text="Search", width = 7,
                               command=cmdtwo)

And you have two windows which don't collide!

This is an interesting question and touches on a very basic concept in Bourne shell and subshell. Here I provide a solution that is different from the previous solutions by doing some kind of filtering. I will give an example that may be useful in real life. This is a fragment for checking that downloaded files conform to a known checksum. The checksum file look like the following (Showing just 3 lines):

49174 36326 dna_align_feature.txt.gz
54757     1 dna.txt.gz
55409  9971 exon_transcript.txt.gz

The shell script:

#!/bin/sh

.....

failcnt=0 # this variable is only valid in the parent shell
#variable xx captures all the outputs from the while loop
xx=$(cat ${checkfile} | while read -r line; do
    num1=$(echo $line | awk '{print $1}')
    num2=$(echo $line | awk '{print $2}')
    fname=$(echo $line | awk '{print $3}')
    if [ -f "$fname" ]; then
        res=$(sum $fname)
        filegood=$(sum $fname | awk -v na=$num1 -v nb=$num2 -v fn=$fname '{ if (na == $1 && nb == $2) { print "TRUE"; } else { print "FALSE"; }}')
        if [ "$filegood" = "FALSE" ]; then
            failcnt=$(expr $failcnt + 1) # only in subshell
            echo "$fname BAD $failcnt"
        fi
    fi
done | tail -1) # I am only interested in the final result
# you can capture a whole bunch of texts and do further filtering
failcnt=${xx#* BAD } # I am only interested in the number
# this variable is in the parent shell
echo failcnt $failcnt
if [ $failcnt -gt 0 ]; then
    echo $failcnt files failed
else
    echo download successful
fi

The parent and subshell communicate through the echo command. You can pick some easy to parse text for the parent shell. This method does not break your normal way of thinking, just that you have to do some post processing. You can use grep, sed, awk, and more for doing so.

A simpler SHA-1 method: (updated from the commenter's suggestions, also using a massively more efficient byte->string algorithm)

String sha1Hash( String toHash )
{
    String hash = null;
    try
    {
        MessageDigest digest = MessageDigest.getInstance( "SHA-1" );
        byte[] bytes = toHash.getBytes("UTF-8");
        digest.update(bytes, 0, bytes.length);
        bytes = digest.digest();

        // This is ~55x faster than looping and String.formating()
        hash = bytesToHex( bytes );
    }
    catch( NoSuchAlgorithmException e )
    {
        e.printStackTrace();
    }
    catch( UnsupportedEncodingException e )
    {
        e.printStackTrace();
    }
    return hash;
}

// http://stackoverflow.com/questions/9655181/convert-from-byte-array-to-hex-string-in-java
final protected static char[] hexArray = "0123456789ABCDEF".toCharArray();
public static String bytesToHex( byte[] bytes )
{
    char[] hexChars = new char[ bytes.length * 2 ];
    for( int j = 0; j < bytes.length; j++ )
    {
        int v = bytes[ j ] & 0xFF;
        hexChars[ j * 2 ] = hexArray[ v >>> 4 ];
        hexChars[ j * 2 + 1 ] = hexArray[ v & 0x0F ];
    }
    return new String( hexChars );
}

For anyone interested, this one worked for me in Ubuntu:

1. Go to .ssh directory.

   $ cd ~/.ssh
   

2. Remove the known_hosts file.

   $ rm known_hosts
   

3. Re-push your Git changes.

A recent web.config change may be in the wrong web.config file.

A <machineKey...> property had been added to Views/web.config. No matter how many Cleans and Rebuilds the error remained. The fix was to move the property into the root /web.config.

After some tinkering for a while with different solutions i found out that one must create a notification channel in Android 8.1 and above.

private fun startForeground() {
    val channelId =
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                createNotificationChannel("my_service", "My Background Service")
            } else {
                // If earlier version channel ID is not used
                // https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#NotificationCompat.Builder(android.content.Context)
                ""
            }

    val notificationBuilder = NotificationCompat.Builder(this, channelId )
    val notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setPriority(PRIORITY_MIN)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build()
    startForeground(101, notification)
}

@RequiresApi(Build.VERSION_CODES.O)
private fun createNotificationChannel(channelId: String, channelName: String): String{
    val chan = NotificationChannel(channelId,
            channelName, NotificationManager.IMPORTANCE_NONE)
    chan.lightColor = Color.BLUE
    chan.lockscreenVisibility = Notification.VISIBILITY_PRIVATE
    val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    service.createNotificationChannel(chan)
    return channelId
}

From my understanding background services are now displayed as normal notifications that the user then can select to not show by deselecting the notification channel.

Update: Also don't forget to add the foreground permission as required Android P:

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

You can combine pseudo-elements! Sorry guys, I figured this one out myself shortly after posting the question. Maybe it's less commonly used because of compatibility issues.

li:last-child:before { content: "and "; }

li:last-child:after { content: "."; }

This works swimmingly. CSS is kind of amazing.

I had same problem regarding that i.e A network-related or instance-specific error occurred while establishing a connection to SQL Server.

I was using SQL Server 2005 (.\sqlexpress)` and worked fine but suddenly services stopped and gave me error.

I solved it like this,

Start -> Search Box - > Sql Configuration Manager -> SQL Server 2005 Services >and just Change Your SQL Server (SQLEXPRESS) State to Running by right clicking that service Sate.

For ASP.NET web pages (not MVC), you can use Sys.UI.DomEvent object as wrapper of native event.

<div onclick="event.stopPropagation();" ...

or, pass event as a parameter to inner function:

<div onclick="someFunction(event);" ...

and in someFunction:

function someFunction(event){
    event.stopPropagation(); // here Sys.UI.DomEvent.stopPropagation() method is used
    // other onclick logic
}

Published by Microsoft in Standard Date and Time Format Strings:

dataGrid.Columns[2].DefaultCellStyle.Format = "d"; // Short date

That should format the date according to the person's location settings.

This is part of Microsoft's larger collection of Formatting Types in .NET.

After hours of searching I think my problem was that command yum install php-soap installs the latest version of soap for the latest php version.

My php version was 7.027, but latest php version is 7.2 so I had to search for the right soap version and finaly found it HERE!

yum install rh-php70-php-soap

Now php -m | grep -i soap works, Output: soap

Try jQuery.inArray()

Here is a jsfiddle link using the same code : http://jsfiddle.net/yrshaikh/SUKn2/

The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0

Example Code :

<html>
   <head>
      <style>
         div { color:blue; }
         span { color:red; }
  </style>
      <script src="http://code.jquery.com/jquery-latest.js"></script>
   </head>
   <body>    
      <div>"John" found at <span></span></div>
      <div>4 found at <span></span></div>
      <div>"Karl" not found, so <span></span></div>
      <div>
         "Pete" is in the array, but not at or after index 2, so <span></span>
      </div>
      <script>
         var arr = [ 4, "Pete", 8, "John" ];
         var $spans = $("span");
         $spans.eq(0).text(jQuery.inArray("John", arr));
         $spans.eq(1).text(jQuery.inArray(4, arr));
         $spans.eq(2).text(jQuery.inArray("Karl", arr));
         $spans.eq(3).text(jQuery.inArray("Pete", arr, 2));
      </script>  
   </body>
</html>

Output:

"John" found at 3
4 found at 0
"Karl" not found, so -1
"Pete" is in the array, but not at or after index 2, so -1

It might be help someone. Similar example.

This is our Codable class to bind data. You can easily create this class using SwiftyJsonAccelerator

 class ModelPushNotificationFilesFile: Codable {

  enum CodingKeys: String, CodingKey {
    case url
    case id
    case fileExtension = "file_extension"
    case name
  }

  var url: String?
  var id: Int?
  var fileExtension: String?
  var name: String?

  init (url: String?, id: Int?, fileExtension: String?, name: String?) {
    self.url = url
    self.id = id
    self.fileExtension = fileExtension
    self.name = name
  }

  required init(from decoder: Decoder) throws {
    let container = try decoder.container(keyedBy: CodingKeys.self)
    url = try container.decodeIfPresent(String.self, forKey: .url)
    id = try container.decodeIfPresent(Int.self, forKey: .id)
    fileExtension = try container.decodeIfPresent(String.self, forKey: .fileExtension)
    name = try container.decodeIfPresent(String.self, forKey: .name)
  }

}

This is Json String

    let jsonString = "[{\"name\":\"\",\"file_extension\":\"\",\"id\":10684,\"url\":\"https:\\/\\/homepages.cae.wisc.edu\\/~ece533\\/images\\/tulips.png\"},

{\"name\":\"\",\"file_extension\":\"\",\"id\":10684,\"url\":\"https:\\/\\/homepages.cae.wisc.edu\\/~ece533\\/images\\/arctichare.png\"},

{\"name\":\"\",\"file_extension\":\"\",\"id\":10684,\"url\":\"https:\\/\\/homepages.cae.wisc.edu\\/~ece533\\/images\\/serrano.png\"},

{\"name\":\"\",\"file_extension\":\"\",\"id\":10684,\"url\":\"https:\\/\\/homepages.cae.wisc.edu\\/~ece533\\/images\\/peppers.png\"},

{\"name\":\"\",\"file_extension\":\"\",\"id\":10684,\"url\":\"https:\\/\\/homepages.cae.wisc.edu\\/~ece533\\/images\\/pool.png\"}]"

Here we convert to swift object.

   let jsonData = Data(jsonString.utf8)

        let decoder = JSONDecoder()

        do {
            let fileArray = try decoder.decode([ModelPushNotificationFilesFile].self, from: jsonData)
            print(fileArray)
            print(fileArray[0].url)
        } catch {
            print(error.localizedDescription)
        }

I'm recently doing a project and using collections.Counter.(Which tortured me).

The Counter in collections have a very very bad performance in my opinion. It's just a class wrapping dict().

What's worse, If you use cProfile to profile its method, you should see a lot of '__missing__' and '__instancecheck__' stuff wasting the whole time.

Be careful using its most_common(), because everytime it would invoke a sort which makes it extremely slow. and if you use most_common(x), it will invoke a heap sort, which is also slow.

Btw, numpy's bincount also have a problem: if you use np.bincount([1,2,4000000]), you will get an array with 4000000 elements.

Here is a method using a lookup table of thresholds and associated colours to map the colours to the variable of interest.

 # make a grid 'Grd' of points and number points for side of square 'GrdD'
Grd <- expand.grid(seq(0.5,400.5,10),seq(0.5,400.5,10))
GrdD <- length(unique(Grd$Var1))

# Add z-values to the grid points
Grd$z <- rnorm(length(Grd$Var1), mean = 10, sd =2)

# Make a vector of thresholds 'Brks' to colour code z 
Brks <- c(seq(0,18,3),Inf)

# Make a vector of labels 'Lbls' for the colour threhsolds
Lbls <- Lbls <- c('0-3','3-6','6-9','9-12','12-15','15-18','>18')

# Make a vector of colours 'Clrs' for to match each range
Clrs <- c("grey50","dodgerblue","forestgreen","orange","red","purple","magenta")

# Make up lookup dataframe 'LkUp' of the lables and colours 
LkUp <- data.frame(cbind(Lbls,Clrs),stringsAsFactors = FALSE)

# Add a new variable 'Lbls' the grid dataframe mapping the labels based on z-value
Grd$Lbls <- as.character(cut(Grd$z, breaks = Brks, labels = Lbls))

# Add a new variable 'Clrs' to the grid dataframe based on the Lbls field in the grid and lookup table
Grd <- merge(Grd,LkUp, by.x = 'Lbls')

# Plot the grid using the 'Clrs' field for the colour of each point
plot(Grd$Var1,
     Grd$Var2,
     xlim = c(0,400),
     ylim = c(0,400),
     cex = 1.0,
     col = Grd$Clrs,
     pch = 20,
     xlab = 'mX',
     ylab = 'mY',
     main = 'My Grid',
     axes = FALSE,
     labels = FALSE,
     las = 1
)

axis(1,seq(0,400,100))
axis(2,seq(0,400,100),las = 1)
box(col = 'black')

legend("topleft", legend = Lbls, fill = Clrs, title = 'Z')

I've chmoded my keypair to 600 in order to get into my personal instance last night,

And this is the way it is supposed to be.

From the EC2 documentation we have "If you're using OpenSSH (or any reasonably paranoid SSH client) then you'll probably need to set the permissions of this file so that it's only readable by you." The Panda documentation you link to links to Amazon's documentation but really doesn't convey how important it all is.

The idea is that the key pair files are like passwords and need to be protected. So, the ssh client you are using requires that those files be secured and that only your account can read them.

Setting the directory to 700 really should be enough, but 777 is not going to hurt as long as the files are 600.

Any problems you are having are client side, so be sure to include local OS information with any follow up questions!

Any server side stuff such as php declaration must get evaluated in the host file (file with a .php extension) inside the script tags such as below

<script type="text/javascript">
    var1 = "<?php echo 'Hello';?>";
</script>

Then in the .js file, you can use the variable

alert(var1);

If you try to evaluate php declaration in the .js file, it will NOT work

The COM threading model is called an "apartment" model, where the execution context of initialized COM objects is associated with either a single thread (Single Thread Apartment) or many threads (Multi Thread Apartment). In this model, a COM object, once initialized in an apartment, is part of that apartment for the duration of its runtime.

The STA model is used for COM objects that are not thread safe. That means they do not handle their own synchronization. A common use of this is a UI component. So if another thread needs to interact with the object (such as pushing a button in a form) then the message is marshalled onto the STA thread. The windows forms message pumping system is an example of this.

If the COM object can handle its own synchronization then the MTA model can be used where multiple threads are allowed to interact with the object without marshalled calls.

You probably haven't added a reference to Microsoft XML (any version) for Dim objHTTP As New MSXML2.XMLHTTP in the VBA window's Tools/References... dialog.

Also, it's a good idea to avoid using late binding (CreateObject...); better to use early binding (Dim objHTTP As New MSXML2.XMLHTTP), as early binding allows you to use Intellisense to list the members and do all sorts of design-time validation.

Actually Alix Axel, above regex is wrong in latitude, longitude ranges point of view.

Latitude measurements range from –90° to +90° Longitude measurements range from –180° to +180°

So the regex given below validates more accurately.
Also, as per my thought no one should restrict decimal point in latitude/longitude.

^([-+]?\d{1,2}([.]\d+)?),\s*([-+]?\d{1,3}([.]\d+)?)$

OR for Objective C

^([-+]?\\d{1,2}([.]\\d+)?),\\s*([-+]?\\d{1,3}([.]\\d+)?)$

Are you trying to do something like this?

>>> strs = [s.strip('\(\)') for s in ['some\\', '(list)', 'of', 'strings']]
>>> strs 
['some', 'list', 'of', 'strings']

This one is similar to @Wilhelm's solution. The loop automates based on a range created by evaluating the populated date column. This was slapped together based strictly on the conversation here and screenshots.

Please note: This assumes that the headers will always be on the same row (row 8). Changing the first row of data (moving the header up/down) will cause the range automation to break unless you edit the range block to take in the header row dynamically. Other assumptions include that VOL and CAPACITY formula column headers are named "Vol" and "Cap" respectively.

Sub Loop3()

Dim dtCnt As Long
Dim rng As Range
Dim frmlas() As String

Application.ScreenUpdating = False

'The following code block sets up the formula output range
dtCnt = Sheets("Loop").Range("A1048576").End(xlUp).Row              'lowest date column populated
endHead = Sheets("Loop").Range("XFD8").End(xlToLeft).Column         'right most header populated
Set rng = Sheets("Loop").Range(Cells(9, 2), Cells(dtCnt, endHead))  'assigns range for automation

ReDim frmlas(1)      'array assigned to formula strings
    'VOL column formula
frmlas(0) = "VOL FORMULA"
    'CAPACITY column formula
frmlas(1) = "CAP FORMULA"

For i = 1 To rng.Columns.count
If rng(0, i).Value = "Vol" Then         'checks for volume formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula= frmlas(0)    'inserts volume formula
    Next j
ElseIf rng(0, i).Value = "Cap" Then     'checks for capacity formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula = frmlas(1)   'inserts capacity formula
    Next j
End If
Next i

Application.ScreenUpdating = True

End Sub

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

Where is your problem??

For the stored procedure, just create:

CREATE PROCEDURE dbo.ReadEmployees @EmpID INT
AS
   SELECT *  -- I would *strongly* recommend specifying the columns EXPLICITLY
   FROM dbo.Emp
   WHERE ID = @EmpID

That's all there is.

From your ASP.NET application, just create a SqlConnection and a SqlCommand (don't forget to set the CommandType = CommandType.StoredProcedure)

DataTable tblEmployees = new DataTable();

using(SqlConnection _con = new SqlConnection("your-connection-string-here"))
using(SqlCommand _cmd = new SqlCommand("ReadEmployees", _con))
{
    _cmd.CommandType = CommandType.StoredProcedure;

    _cmd.Parameters.Add(new SqlParameter("@EmpID", SqlDbType.Int));
    _cmd.Parameters["@EmpID"].Value = 42;

    SqlDataAdapter _dap = new SqlDataAdapter(_cmd);

    _dap.Fill(tblEmployees);
}

YourGridView.DataSource = tblEmployees;
YourGridView.DataBind();

and then fill e.g. a DataTable with that data and bind it to e.g. a GridView.

In JSF 2.2 it's possible to use passthrough elements:

<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:jsf="http://xmlns.jcp.org/jsf">
    ...
    <div jsf:id="id1" />
    ...
</html>

The requirement is to have at least one attribute in the element using jsf namespace.

Remove the visible="false" attribute and add a CSS class that is not visible by default. Then you should be able to reference the dropdown by the correct id, for example:

$("#ctl00_cphTest_test1").show();

Above ID you should serach for in the source of the rendered page in your browser.

What I did was first I installed python 3.7

brew install python3
brew unlink python

then I installed python 3.6.5 using above link

brew install --ignore-dependencies https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb --ignore-dependencies

I found the GeoCoder javascript a little buggy when I included it in my jsp files.

You can also try this:

    var lat = "43.7667855" ;
    var long = "-79.2157321" ;
    var url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="
       +lat+","+long+"&sensor=false";
    $.get(url).success(function(data) {
       var loc1 = data.results[0];
       var county, city;
         $.each(loc1, function(k1,v1) {
            if (k1 == "address_components") {
               for (var i = 0; i < v1.length; i++) {
                  for (k2 in v1[i]) {
                     if (k2 == "types") {
                        var types = v1[i][k2];
                        if (types[0] =="sublocality_level_1") {
                            county = v1[i].long_name;
                            //alert ("county: " + county);
                        } 
                        if (types[0] =="locality") {
                           city = v1[i].long_name;
                           //alert ("city: " + city);
                       } 
                     }

                  }          

               }

            }

         });
         $('#city').html(city); 
    }); 

My answer doesn't contribute anything new, just a concrete example I encountered.

import gtk.gdk

w = gtk.gdk.get_default_root_window()

PyDev showed the error message "Undefined variable from import: get_default_root_window()"

In the python shell you can see that this is a 'built-in' module as mentioned in a answer above:

>>> import gtk.gdk
>>> gtk.gdk
<module 'gtk.gdk' (built-in)>

Now under Window->Preferences->PyDev->Interpreters->Python Interpreter, I selected the tab 'Forced Builtins' and added 'gtk.gdk' to the list.

Now the error message didn't show anymore.

You have to first convert your object literal to a Prototype Hash:

// Store your object literal
var obj = {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}}

// Iterate like so.  The $H() construct creates a prototype-extended Hash.
$H(obj).each(function(pair){
  alert(pair.key);
  alert(pair.value);
});

# here database details      
mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');

$sql = "SELECT username FROM userregistraton";
$result = mysql_query($sql);

echo "<select name='username'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['username'] ."'>" . $row['username'] ."</option>";
}
echo "</select>";

# here username is the column of my table(userregistration)
# it works perfectly

And for the plain js answer if anyone might be interested;

var count = document.getElementsByClassName("item");

Cheers.

If you are allowed to change the code of the document inside your iframe and that content is visible only using its parent window, simply add the following CSS in your iframe:

body {
    overflow:hidden;
}

Here a very simple example:

http://jsfiddle.net/u5gLoav9/

This solution allow you to:

• Keep you HTML5 valid as it does not need scrolling="no" attribute on the iframe (this attribute in HTML5 has been deprecated).

• Works on the majority of browsers using CSS overflow:hidden

• No JS or jQuery necessary.

Notes:

To disallow scroll-bars horizontally, use this CSS instead:

overflow-x: hidden;

Pattern p = Pattern.compile("tom"); //the regular-expression pattern
Matcher m = p.matcher("(bob)(tom)(harry)"); //The data to find matches with

while (m.find()) {
    //do something???
}   

Use regex to find a match maybe?

Or create an array

 String[] a = new String[]{
        "tom",
        "bob",
        "harry"
 };

 if(a.contains(stringtomatch)){
     //do something
 }

You may use Perl on the commandline:

perl -e 'my @b=(); while(<>) {push(@b, $_);}; print join("", reverse(@b));' orig > rev

The simplest is just

string filename = ...
Thread thread = new Thread(() => download(filename));
thread.Start();

The advantage(s) of this (over ParameterizedThreadStart) is that you can pass multiple parameters, and you get compile-time checking without needing to cast from object all the time.

Gone views returns 0 as height if app in background. This my code (1oo% works)

fun View.postWithTreeObserver(postJob: (View, Int, Int) -> Unit) {
    viewTreeObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
        override fun onGlobalLayout() {
            val widthSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)
            val heightSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)
            measure(widthSpec, heightSpec)
            postJob(this@postWithTreeObserver, measuredWidth, measuredHeight)
            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
                @Suppress("DEPRECATION")
                viewTreeObserver.removeGlobalOnLayoutListener(this)
            } else {
                viewTreeObserver.removeOnGlobalLayoutListener(this)
            }
        }
    })
}

You can define a generic function like this:

@SuppressWarnings("unchecked")
public static <T> List<T> newFixedSizeList(int size) {
    return (List<T>)Arrays.asList(new Object[size]);
}

And

List<String> s = newFixedSizeList(3);  // All elements are initialized to null
s.set(0, "zero");
s.add("three");  // throws java.lang.UnsupportedOperationException

You can do this with a single statement - assuming you are calling it from a JDBC-like connector with in/out parameters functionality:

insert into batch(batchid, batchname) 
values (batch_seq.nextval, 'new batch')
returning batchid into :l_batchid;

or, as a pl-sql script:

variable l_batchid number;

insert into batch(batchid, batchname) 
values (batch_seq.nextval, 'new batch')
returning batchid into :l_batchid;

select :l_batchid from dual;

The object-fit CSS property sets how the content of a replaced element, such as an img or video, should be resized to fit its container.

Magically, object fit also works on a canvas element. No JavaScript needed, and the canvas doesn't stretch, automatically fills to proportion.

canvas {
    width: 100%;
    object-fit: contain;
}

You may use Oracle pipelined functions

Basically, when you would like a PLSQL (or java or c) routine to be the «source» of data -- instead of a table -- you would use a pipelined function.

Simple Example - Generating Some Random Data
How could you create N unique random numbers depending on the input argument?

create type array
as table of number;


create function  gen_numbers(n in number default null)
return array
PIPELINED
as
begin
  for i in 1 .. nvl(n,999999999)
  loop
     pipe row(i);
 end loop;
 return;
end;

Suppose we needed three rows for something. We can now do that in one of two ways:

select * from TABLE(gen_numbers(3));

COLUMN_VALUE

       1
       2
       3

or

select * from TABLE(gen_numbers)
 where rownum <= 3;

COLUMN_VALUE

       1
       2
       3

A linear search starts at the beginning of a list of values, and checks 1 by 1 in order for the result you are looking for.

A binary search starts in the middle of a sorted array, and determines which side (if any) the value you are looking for is on. That "half" of the array is then searched again in the same fashion, dividing the results in half by two each time.

If you prefer splitting a CSV list in SQL, there's a different way to do it using Common Table Expressions (CTEs). See Efficient way to string split using CTE.

In Linux I've resolved this by deleting all the folders with names starting as ".AndroidStudio" in my home directory and then rerunning the Android Studio.

This worked for me. Make sure to put "ff" between 0x and color code. Like this 0xff2196F3

Drawable mDrawable = ContextCompat.getDrawable(MainActivity.this,R.drawable.ic_vector_home);
                    mDrawable.setColorFilter(new
                            PorterDuffColorFilter(0xff2196F3,PorterDuff.Mode.SRC_IN));

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

Here's a nice way for child objects to have access to parent properties and methods using JavaScript's prototype chain, and it's compatible with Internet Explorer. JavaScript searches the prototype chain for methods and we want the child’s prototype chain to looks like this:

Child instance -> Child’s prototype (with Child methods) -> Parent’s prototype (with Parent methods) -> Object prototype -> null

The child methods can also call shadowed parent methods, as shown at the three asterisks *** below.

Here’s how:

//Parent constructor_x000D_
function ParentConstructor(firstName){_x000D_
    //add parent properties:_x000D_
    this.parentProperty = firstName;_x000D_
}_x000D_
_x000D_
//add 2 Parent methods:_x000D_
ParentConstructor.prototype.parentMethod = function(argument){_x000D_
    console.log(_x000D_
            "Parent says: argument=" + argument +_x000D_
            ", parentProperty=" + this.parentProperty +_x000D_
            ", childProperty=" + this.childProperty_x000D_
    );_x000D_
};_x000D_
_x000D_
ParentConstructor.prototype.commonMethod = function(argument){_x000D_
    console.log("Hello from Parent! argument=" + argument);_x000D_
};_x000D_
_x000D_
//Child constructor    _x000D_
function ChildConstructor(firstName, lastName){_x000D_
    //first add parent's properties_x000D_
    ParentConstructor.call(this, firstName);_x000D_
_x000D_
    //now add child's properties:_x000D_
    this.childProperty = lastName;_x000D_
}_x000D_
_x000D_
//insert Parent's methods into Child's prototype chain_x000D_
var rCopyParentProto = Object.create(ParentConstructor.prototype);_x000D_
rCopyParentProto.constructor = ChildConstructor;_x000D_
ChildConstructor.prototype = rCopyParentProto;_x000D_
_x000D_
//add 2 Child methods:_x000D_
ChildConstructor.prototype.childMethod = function(argument){_x000D_
    console.log(_x000D_
            "Child says: argument=" + argument +_x000D_
            ", parentProperty=" + this.parentProperty +_x000D_
            ", childProperty=" + this.childProperty_x000D_
    );_x000D_
};_x000D_
_x000D_
ChildConstructor.prototype.commonMethod = function(argument){_x000D_
    console.log("Hello from Child! argument=" + argument);_x000D_
_x000D_
    // *** call Parent's version of common method_x000D_
    ParentConstructor.prototype.commonMethod(argument);_x000D_
};_x000D_
_x000D_
//create an instance of Child_x000D_
var child_1 = new ChildConstructor('Albert', 'Einstein');_x000D_
_x000D_
//call Child method_x000D_
child_1.childMethod('do child method');_x000D_
_x000D_
//call Parent method_x000D_
child_1.parentMethod('do parent method');_x000D_
_x000D_
//call common method_x000D_
child_1.commonMethod('do common method');

At runtime, you know what style you want your button to have. So beforehand, in xml in the layout folder, you can have all ready to go buttons with the styles you need. So in the layout folder, you might have a file named: button_style_1.xml. The contents of that file might look like:

<?xml version="1.0" encoding="utf-8"?>
<Button
    android:id="@+id/styleOneButton"
    style="@style/FirstStyle" />

If you are working with fragments, then in onCreateView you inflate that button, like:

Button firstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

where container is the ViewGroup container associated with the onCreateView method you override when creating your fragment.

Need two more such buttons? You create them like this:

Button secondFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);
Button thirdFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

You can customize those buttons:

secondFirstStyleBtn.setText("My Second");
thirdFirstStyleBtn.setText("My Third");

Then you add your customized, stylized buttons to the layout container you also inflated in the onCreateView method:

_stylizedButtonsContainer = (LinearLayout) rootView.findViewById(R.id.stylizedButtonsContainer);

_stylizedButtonsContainer.addView(firstStyleBtn);
_stylizedButtonsContainer.addView(secondFirstStyleBtn);
_stylizedButtonsContainer.addView(thirdFirstStyleBtn);

And that's how you can dynamically work with stylized buttons.

I don't think you can "legally" load only part of an XML file, since then it would be malformed (there would be a missing closing element somewhere).

Using LINQ-to-XML, you can do var doc = XDocument.Load("yourfilepath"). From there its just a matter of querying the data you want, say like this:

var authors = doc.Root.Elements().Select( x => x.Element("Author") );

HTH.

EDIT:

Okay, just to make this a better sample, try this (with @JWL_'s suggested improvement):

using System;
using System.Xml.Linq;

namespace ConsoleApplication1 {
    class Program {
        static void Main( string[] args )  {
            XDocument doc = XDocument.Load( "XMLFile1.xml" );
            var authors = doc.Descendants( "Author" );
            foreach ( var author in authors ) {
                Console.WriteLine( author.Value );
            }
            Console.ReadLine();
        }
    }
}

You will need to adjust the path in XDocument.Load() to point to your XML file, but the rest should work. Ask questions about which parts you don't understand.

Suppose logical address space is **32 bit so total possible logical entries will be 2^32 and other hand suppose each page size is 4 byte then size of one page is *2^2*2^10=2^12...* now we know that no. of pages in page table is pages=total possible logical address entries/page size so pages=2^32/2^12 =2^20 Now suppose that each entry in page table takes 4 bytes then total size of page table in *physical memory will be=2^2*2^20=2^22=4mb***

The function itself looks fine to me. The problem could be that you aren't allocating enough space for your string to pad that many characters onto it. You could avoid this problem in the future by passing a size_of_string argument to the function and make sure you don't pad the string when the length is about to be greater than the size.

MySQL doesn't reduce the size of ibdata1. Ever. Even if you use optimize table to free the space used from deleted records, it will reuse it later.

An alternative is to configure the server to use innodb_file_per_table, but this will require a backup, drop database and restore. The positive side is that the .ibd file for the table is reduced after an optimize table.

This problem solved with

 "Origin, X-Requested-With, Content-Type, Accept, Authorization"

Particular in my project (express.js/nodejs)

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Methods", "GET,HEAD,OPTIONS,POST,PUT");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
  next();
});

Update:

Every time error: Access-Control-Allow-Headers is not allowed by itself in preflight response error you can see what wrong with chrome developer tool:

above error is missing Content-Type so add string Content-Type to Access-Control-Allow-Headers

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

The best way is to use closures, because the window object gets very, very cluttered with properties.

Sometimes value stored in Database could contain spaces so running this could be fail

String.Equals(row.Name, "test", StringComparison.OrdinalIgnoreCase)

Solution to this problems is to remove space then convert its case then select like this

 return db.UsersTBs.Where(x => x.title.ToString().ToLower().Replace(" ",string.Empty).Equals(customname.ToLower())).FirstOrDefault();

Note in this case

customname is value to match with Database value

UsersTBs is class

title is the Database column

I have created a json file which contain conutry name,ISO and country code. Here is a link. Conutries Code

Above File Example [{ "Name": "Afghanistan", "ISO": "af", "Code": "93" }]

A quick workaround is using window.addEventListener instead of document.addEventListener.

You can try define in your LINQ expression only the field's that you will need.

Example. Imagine that you have an Model with Id, Name, Phone and Picture (byte array) and need to load from json into an select list.

LINQ Query:

var listItems = (from u in Users where u.name.Contains(term) select u).ToList();

The problem here is "select u" that get all fields. So, if you have big pictures, booomm.

How to solve? very, very simple.

var listItems = (from u in Users where u.name.Contains(term) select new {u.Id, u.Name}).ToList();

The best practices is select only the field that you will use.

Remember. This is a simple tip, but can help many ASP.NET MVC developpers.

TL;DR:

The ActionListeners (there can be multiple) execute in the order they were registered BEFORE the action

Long Answer:

A business action typically invokes an EJB service and if necessary also sets the final result and/or navigates to a different view if that is not what you are doing an actionListener is more appropriate i.e. for when the user interacts with the components, such as h:commandButton or h:link they can be handled by passing the name of the managed bean method in actionListener attribute of a UI Component or to implement an ActionListener interface and pass the implementation class name to actionListener attribute of a UI Component.

image has a shape of (64,64,3).

Your input placeholder _x have a shape of (?, 64,64,3).

The problem is that you're feeding the placeholder with a value of a different shape.

You have to feed it with a value of (1, 64, 64, 3) = a batch of 1 image.

Just reshape your image value to a batch with size one.

image = array(img).reshape(1, 64,64,3)

P.S: the fact that the input placeholder accepts a batch of images, means that you can run predicions for a batch of images in parallel. You can try to read more than 1 image (N images) and than build a batch of N image, using a tensor with shape (N, 64,64,3)

How wide is the text column?

With a GROUP BY there's not much you can do to avoid a data scan (at least an index scan).

I'd recommend:

1. If possible, changing the schema to remove duplication of text data. This way the count will happen on a narrow foreign key field in the 'many' table.

2. Alternatively, creating a generated column with a HASH of the text, then GROUP BY the hash column. Again, this is to decrease the workload (scan through a narrow column index)

Edit:

Your original question did not quite match your edit. I'm not sure if you're aware that the COUNT, when used with a GROUP BY, will return the count of items per group and not the count of items in the entire table.

for complette URL with protocol, servername and parameters:

 $base_url = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']=='on' ? 'https' : 'http' ) . '://' .  $_SERVER['HTTP_HOST'];
 $url = $base_url . $_SERVER["REQUEST_URI"];

The & means that the function accepts the address (or reference) to a variable, instead of the value of the variable.

For example, note the difference between this:

void af(int& g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

And this (without the &):

void af(int g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

I had the same problem error that is shown, i solve it by adding

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

I had this problem cause i exceeded the 65K methods dex limit imposed by Android i used so many libraries

A snippet I found at http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=21021 that helped me:

select t.name TableName, i.rows Records
from sysobjects t, sysindexes i
where t.xtype = 'U' and i.id = t.id and i.indid in (0,1)
order by TableName;

Also for openCV in python you can do:

img = cv2.imread('myImage.jpg')
height, width, channels = img.shape 

Within PowerShell ISE you can hit Ctrl+J to open the Start Snipping menu and select Comment block:

pod setup --verbose 

I am running the above mentioned command right now but as mentioned by @Joe Blow, it shows absolutely no information on the progress.

But if you open the Activity Monitor on Mac (Task Manager on Windows?), under the 'Network' tab you will see a process named 'git-remote-https' and it shows the size of 'Received Bytes' increasing. After downloading about 300MB it stopped and then I could see further progress in the Terminal window.

You can also use this command to reload the ~/.bash_profile for that user. Make sure to use the dash.

httpOnly is supported as of Tomcat 6.0.19 and Tomcat 5.5.28.

See the changelog entry for bug 44382.

The last comment for bug 44382 states, "this has been applied to 5.5.x and will be included in 5.5.28 onwards." However, it does not appear that 5.5.28 has been released.

The httpOnly functionality can be enabled for all webapps in conf/context.xml:

<Context useHttpOnly="true">
...
</Context>

My interpretation is that it also works for an individual context by setting it on the desired Context entry in conf/server.xml (in the same manner as above).

If it is only about nltk, I once faced similar problem. Try following guide for installation. Install NLTK

If you are sure it doesn't work with any other module, you may have problem with different versions of Python installed.

Or Give It a Try to see if it says pip is already installed.:

sudo apt-get install python-pip python-dev build-essential 

and see if it works.

This should work:

reload(my.module)

From the Python docs

Reload a previously imported module. The argument must be a module object, so it must have been successfully imported before. This is useful if you have edited the module source file using an external editor and want to try out the new version without leaving the Python interpreter.

If running Python 3.4 and up, do import importlib, then do importlib.reload(nameOfModule).

Don't forget the caveats of using this method:

• When a module is reloaded, its dictionary (containing the module’s global variables) is retained. Redefinitions of names will override the old definitions, so this is generally not a problem, but if the new version of a module does not define a name that was defined by the old version, the old definition is not removed.

• If a module imports objects from another module using from ... import ..., calling reload() for the other module does not redefine the objects imported from it — one way around this is to re-execute the from statement, another is to use import and qualified names (module.*name*) instead.

• If a module instantiates instances of a class, reloading the module that defines the class does not affect the method definitions of the instances — they continue to use the old class definition. The same is true for derived classes.

ole@T:~$ docker run -it --rm alpine /bin/ash
(inside container) / # 

Options used above:

• /bin/ash is Ash (Almquist Shell) provided by BusyBox
• --rm Automatically remove the container when it exits (docker run --help)
• -i Interactive mode (Keep STDIN open even if not attached)
• -t Allocate a pseudo-TTY

Since 2.5 you can use equivalent of C’s ”?:” ternary conditional operator and the syntax is:

[on_true] if [expression] else [on_false]

So your example is fine, but you've to simply add else, like:

print a if b else ''

This solution did the job for me. The RecursiveIteratorIterator lists all directories and files recursively but unsorted. The program filters the list and sorts it.

I'm sure there is a way to write this shorter; feel free to improve it. It is just a code snippet. You may want to pimp it to your purposes.

<?php

$path = '/pth/to/your/directories/and/files';
// an unsorted array of dirs & files
$files_dirs = iterator_to_array( new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path),RecursiveIteratorIterator::SELF_FIRST) );

echo '<html><body><pre>';
// create a new associative multi-dimensional array with dirs as keys and their files
$dirs_files = array();
foreach($files_dirs as $dir){
 if(is_dir($dir) AND preg_match('/\/\.$/',$dir)){
  $d = preg_replace('/\/\.$/','',$dir);
  $dirs_files[$d] = array();
  foreach($files_dirs as $file){
   if(is_file($file) AND $d == dirname($file)){
    $f = basename($file);
    $dirs_files[$d][] = $f;
   }
  }
 }
}
//print_r($dirs_files);

// sort dirs
ksort($dirs_files);

foreach($dirs_files as $dir => $files){
 $c = substr_count($dir,'/');
 echo  str_pad(' ',$c,' ', STR_PAD_LEFT)."$dir\n";
 // sort files
 asort($files);
 foreach($files as $file){
  echo str_pad(' ',$c,' ', STR_PAD_LEFT)."|_$file\n";
 }
}
echo '</pre></body></html>';

The Fibonacci sphere algorithm is great for this. It is fast and gives results that at a glance will easily fool the human eye. You can see an example done with processing which will show the result over time as points are added. Here's another great interactive example made by @gman. And here's a simple implementation in python.

import math


def fibonacci_sphere(samples=1):

    points = []
    phi = math.pi * (3. - math.sqrt(5.))  # golden angle in radians

    for i in range(samples):
        y = 1 - (i / float(samples - 1)) * 2  # y goes from 1 to -1
        radius = math.sqrt(1 - y * y)  # radius at y

        theta = phi * i  # golden angle increment

        x = math.cos(theta) * radius
        z = math.sin(theta) * radius

        points.append((x, y, z))

    return points

1000 samples gives you this:

use LineNumberReader

something like

public static int countLines(File aFile) throws IOException {
    LineNumberReader reader = null;
    try {
        reader = new LineNumberReader(new FileReader(aFile));
        while ((reader.readLine()) != null);
        return reader.getLineNumber();
    } catch (Exception ex) {
        return -1;
    } finally { 
        if(reader != null) 
            reader.close();
    }
}

Since IntelliJ 2016, the location is File | Settings | Build, Execution, Deployment | Compiler | Build process heap size.

I find this elegant as it makes sure it is a string and checks its length:

def empty(mystring):
    assert isinstance(mystring, str)
    if len(mystring) == 0:
        return True
    else:
        return False

As mentioned in the other answers MOQ cannot mock static methods and, as a general rule, one should avoid statics where possible.

Sometimes it is not possible. One is working with legacy or 3rd party code or with even with the BCL methods that are static.

A possible solution is to wrap the static in a proxy with an interface which can be mocked

    public interface IFileProxy {
        void Delete(string path);
    }

    public class FileProxy : IFileProxy {
        public void Delete(string path) {
            System.IO.File.Delete(path);
        }
    }

    public class MyClass {

        private IFileProxy _fileProxy;

        public MyClass(IFileProxy fileProxy) {
            _fileProxy = fileProxy;
        }

        public void DoSomethingAndDeleteFile(string path) {
            // Do Something with file
            // ...
            // Delete
            System.IO.File.Delete(path);
        }

        public void DoSomethingAndDeleteFileUsingProxy(string path) {
            // Do Something with file
            // ...
            // Delete
            _fileProxy.Delete(path);

        }
    }

The downside is that the ctor can become very cluttered if there are a lot of proxies (though it could be argued that if there are a lot of proxies then the class may be trying to do too much and could be refactored)

Another possibility is to have a 'static proxy' with different implementations of the interface behind it

   public static class FileServices {

        static FileServices() {
            Reset();
        }

        internal static IFileProxy FileProxy { private get; set; }

        public static void Reset(){
           FileProxy = new FileProxy();
        }

        public static void Delete(string path) {
            FileProxy.Delete(path);
        }

    }

Our method now becomes

    public void DoSomethingAndDeleteFileUsingStaticProxy(string path) {
            // Do Something with file
            // ...
            // Delete
            FileServices.Delete(path);

    }

For testing, we can set the FileProxy property to our mock. Using this style reduces the number of interfaces to be injected but makes dependencies a bit less obvious (though no more so than the original static calls I suppose).

The best way to do this is using Behaviur Subject, here is an example:

var sub = new rxjs.BehaviorSubject([0, 1])
sub.next([2, 3])
setTimeout(() => {sub.next([4, 5])}, 1500)
sub.subscribe(a => console.log(a)) //2, 3 (current value) -> wait 2 sec -> 4, 5

select LAST_LOAD_TIME, ELAPSED_TIME, MODULE, SQL_TEXT elapsed from v$sql
  order by LAST_LOAD_TIME desc

More complicated example (don't forget to delete or to substitute PATTERN):

select * from (
  select LAST_LOAD_TIME, to_char(ELAPSED_TIME/1000, '999,999,999.000') || ' ms' as TIME,
         MODULE, SQL_TEXT from SYS."V_\$SQL"
    where SQL_TEXT like '%PATTERN%'
    order by LAST_LOAD_TIME desc
  ) where ROWNUM <= 5;

You have to use providers instead of injectables

@Component({
    selector: 'my-app',
    providers: [NameService]
})

Complete code sample here.

If you want to generate 100 numbers that are random, but each number appearing only once, a good way would be to generate an array with the numbers in order, then shuffle it.

Something like this:

$arr = array();

for ($i=1;$i<=101;$i++) {
    $arr[] = $i;
}

shuffle($arr);

print_r($arr);

Output will look something like this:

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Use stringi package and stri_length function

> stri_length(c("ala ma kota","ABC",NA))

Why? Because it is the FASTEST among presented solutions :)

require(microbenchmark)
require(stringi)
require(stringr)
x <- c(letters,NA,paste(sample(letters,2000,TRUE),collapse=" "))
microbenchmark(nchar(x),str_length(x),stri_length(x))
Unit: microseconds
           expr    min     lq  median      uq     max neval
       nchar(x) 11.868 12.776 13.1590 13.6475  41.815   100
  str_length(x) 30.715 33.159 33.6825 34.1360 173.400   100
 stri_length(x)  2.653  3.281  4.0495  4.5380  19.966   100

and also works fine with NA's

nchar(NA)
## [1] 2
stri_length(NA)
## [1] NA

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

This problem explained in MSDN Library and as I understand installing Microsoft's Redistributable Package can help.

But sometimes the following solution can be used (as developer's side solution):

In your Visual Studio, open Project properties -> Configuration properties -> C/C++ -> Code generation and change option Runtime Library to /MT instead of /MD

\d{1,3} will match numbers like 00 or 333 as well which wouldn't be a valid ID.

This is an excellent answer from smink, citing:

ValidIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";

In my case, I pushed several big (> 100Mb) files and then proceeded to remove them. But they were still in the history of my repo, so I had to remove them from it as well.

What did the trick was:

bfg -b 100M  # To remove all blobs from history, whose size is superior to 100Mb
git reflog expire --expire=now --all
git gc --prune=now --aggressive

Then, you need to push force on your branch:

git push origin <your_branch_name> --force

Note: bfg is a tool that can be installed on Linux and macOS using brew:

brew install bfg

For me it was using {{ }} instead of {% %}:

href="{{ static 'bootstrap.min.css' }}"  # wrong
href="{% static 'bootstrap.min.css' %}"  # right

Lets say your data is -

data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }

You can use the data.items() method to get the dictionary elements. Note, in django templates we do NOT put (). Also some users mentioned values[0] does not work, if that is the case then try values.items.

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>

    {% for key, values in data.items %}
    <tr>
        <td>{{key}}</td>
        {% for v in values[0] %}
        <td>{{v}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

Am pretty sure you can extend this logic to your specific dict.

To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.

return render_to_response('some_page.html', {'data': sorted(data.items())})

In template file:

{% for key, value in data %}
    <tr>
        <td> Key: {{ key }} </td> 
        <td> Value: {{ value }} </td>
    </tr>
{% endfor %}

The source file jquery-1.2.6.min.js is not called the jQuery command $() is executed earlier than <..src='jquery-1.2.6.min.js'>.

Please run <.. src="/js/jquery-1.2.6.min.js.."> at first and make sure the src path is right, then execute jquery command

$(document).ready(function() 

Using std::vector<unsigned char>:

#include <vector>
using namespace std;

vector<unsigned char> intToBytes(int paramInt)
{
     vector<unsigned char> arrayOfByte(4);
     for (int i = 0; i < 4; i++)
         arrayOfByte[3 - i] = (paramInt >> (i * 8));
     return arrayOfByte;
}

It can also be done using the IsSelected property of the TreeView item. Here's how I managed it,

public delegate void TreeviewItemSelectedHandler(TreeViewItem item);
public class TreeViewItem
{      
  public static event TreeviewItemSelectedHandler OnItemSelected = delegate { };
  public bool IsSelected 
  {
    get { return isSelected; }
    set 
    { 
      isSelected = value;
      if (value)
        OnItemSelected(this);
    }
  }
}

Then in the ViewModel that contains the data your TreeView is bound to, just subscribe to the event in the TreeViewItem class.

TreeViewItem.OnItemSelected += TreeViewItemSelected;

And finally, implement this handler in the same ViewModel,

private void TreeViewItemSelected(TreeViewItem item)
{
  //Do something
}

And the binding of course,

<Setter Property="IsSelected" Value="{Binding IsSelected}" />    

You can pass the tv_sec parameter to some of the formatting function. Have a look at gmtime, localtime(). Then look at snprintf.

Here's a simple example of how to load JSON data into an Angular model.

I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.

http://www.iNorthwind.com/Service1.svc/getAllCustomers

It returns some JSON data which looks like this:

{ 
    "GetAllCustomersResult" : 
        [
            {
              "CompanyName": "Alfreds Futterkiste",
              "CustomerID": "ALFKI"
            },
            {
              "CompanyName": "Ana Trujillo Emparedados y helados",
              "CustomerID": "ANATR"
            },
            {
              "CompanyName": "Antonio Moreno Taquería",
              "CustomerID": "ANTON"
            }
        ]
    }

..and I want to populate a drop down list with this data, to look like this...

I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.

How would I do it ?

My Angular controller would look like this:

function MikesAngularController($scope, $http) {

    $scope.listOfCustomers = null;

    $http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
         .success(function (data) {
             $scope.listOfCustomers = data.GetAllCustomersResult;
         })
         .error(function (data, status, headers, config) {
             //  Do some error handling here
         });
}

... which fills a "listOfCustomers" variable with this set of JSON data.

Then, in my HTML page, I'd use this:

<div ng-controller='MikesAngularController'>
    <span>Please select a customer:</span>
    <select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>

And that's it. We can now see a list of our JSON data on a web page, ready to be used.

The key to this is in the "ng-options" tag:

customer.CustomerID as customer.CompanyName for customer in listOfCustomers

It's a strange syntax to get your head around !

When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.

This is what you wanna do:

var oldSrc = 'http://example.com/smith.gif';
var newSrc = 'http://example.com/johnson.gif';
$('img[src="' + oldSrc + '"]').attr('src', newSrc);

If the data is not null-terminated, you should use -initWithData:encoding:

NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];

If the data is null-terminated, you should instead use -stringWithUTF8String: to avoid the extra \0 at the end.

NSString* newStr = [NSString stringWithUTF8String:[theData bytes]];

(Note that if the input is not properly UTF-8-encoded, you will get nil.)

Swift variant:

let newStr = String(data: data, encoding: .utf8)
// note that `newStr` is a `String?`, not a `String`.

If the data is null-terminated, you could go though the safe way which is remove the that null character, or the unsafe way similar to the Objective-C version above.

// safe way, provided data is \0-terminated
let newStr1 = String(data: data.subdata(in: 0 ..< data.count - 1), encoding: .utf8)
// unsafe way, provided data is \0-terminated
let newStr2 = data.withUnsafeBytes(String.init(utf8String:))
