Programs & Examples On #Double checked locking

If you're only doing a few of them (and/or the array size is large), then you were on the right track with array_search:

$list = array('string1', 'string2', 'string3');
$k = array_search('string2', $list); //$k = 1;

If you want all (or a lot of them), a loop will prob do you better:

foreach ($list as $key => $value) {
    echo $value . " in " . $key . ", ";
}
// Prints "string1 in 0, string2 in 1, string3 in 2, "

here is a workable sample cod, considering the image orientation:

#define rad(angle) ((angle) / 180.0 * M_PI)
- (CGAffineTransform)orientationTransformedRectOfImage:(UIImage *)img
{
    CGAffineTransform rectTransform;
    switch (img.imageOrientation)
    {
        case UIImageOrientationLeft:
            rectTransform = CGAffineTransformTranslate(CGAffineTransformMakeRotation(rad(90)), 0, -img.size.height);
            break;
        case UIImageOrientationRight:
            rectTransform = CGAffineTransformTranslate(CGAffineTransformMakeRotation(rad(-90)), -img.size.width, 0);
            break;
        case UIImageOrientationDown:
            rectTransform = CGAffineTransformTranslate(CGAffineTransformMakeRotation(rad(-180)), -img.size.width, -img.size.height);
            break;
        default:
            rectTransform = CGAffineTransformIdentity;
    };

    return CGAffineTransformScale(rectTransform, img.scale, img.scale);
}


- (UIImage *)croppedImage:(UIImage*)orignialImage InRect:(CGRect)visibleRect{
    //transform visible rect to image orientation
    CGAffineTransform rectTransform = [self orientationTransformedRectOfImage:orignialImage];
    visibleRect = CGRectApplyAffineTransform(visibleRect, rectTransform);

    //crop image
    CGImageRef imageRef = CGImageCreateWithImageInRect([orignialImage CGImage], visibleRect);
    UIImage *result = [UIImage imageWithCGImage:imageRef scale:orignialImage.scale orientation:orignialImage.imageOrientation];
    CGImageRelease(imageRef);
    return result;
}

Docker provides a couple of examples on how to do it. The lightweight option is to:

Put all of your commands in a wrapper script, complete with testing and debugging information. Run the wrapper script as your CMD. This is a very naive example. First, the wrapper script:

#!/bin/bash

# Start the first process
./my_first_process -D
status=$?
if [ $status -ne 0 ]; then
  echo "Failed to start my_first_process: $status"
  exit $status
fi

# Start the second process
./my_second_process -D
status=$?
if [ $status -ne 0 ]; then
  echo "Failed to start my_second_process: $status"
  exit $status
fi

# Naive check runs checks once a minute to see if either of the processes exited.
# This illustrates part of the heavy lifting you need to do if you want to run
# more than one service in a container. The container will exit with an error
# if it detects that either of the processes has exited.
# Otherwise it will loop forever, waking up every 60 seconds

while /bin/true; do
  ps aux |grep my_first_process |grep -q -v grep
  PROCESS_1_STATUS=$?
  ps aux |grep my_second_process |grep -q -v grep
  PROCESS_2_STATUS=$?
  # If the greps above find anything, they will exit with 0 status
  # If they are not both 0, then something is wrong
  if [ $PROCESS_1_STATUS -ne 0 -o $PROCESS_2_STATUS -ne 0 ]; then
    echo "One of the processes has already exited."
    exit -1
  fi
  sleep 60
done

Next, the Dockerfile:

FROM ubuntu:latest
COPY my_first_process my_first_process
COPY my_second_process my_second_process
COPY my_wrapper_script.sh my_wrapper_script.sh
CMD ./my_wrapper_script.sh

can you please try this: replace the case statement with the below one

Sum(CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END) as Count,

I realize this question is old but I didn't understand Antak's answer and didn't want to use a library so I rolled my own solution.

Solution assumes records is a 2D array, records are all the same length, and that fields are all strings.

def stringifyRecords(records):
    column_widths = [0] * len(records[0])
    for record in records:
        for i, field in enumerate(record):
            width = len(field)
            if width > column_widths[i]: column_widths[i] = width

    s = ""
    for record in records:
        for column_width, field in zip(column_widths, record):
            s += field.ljust(column_width+1)
        s += "\n"

    return s

You've no doubt solved this by now or decided to do something different, but as it has not been answered & I stumbled across this when looking for something similar I thought I'd share my method.

I've taken to using two div sets. One has hidden-xs and is for sm, md & lg device viewing. The other has hidden-sm, -md, -lg and is only for mobile. Now I have a lot more control over the display in my CSS.

You can see a rough idea in this js fiddle where I set the footer and buttons to be smaller when the resolution is of the -xs size.

  <div class="modal-footer">
      <div class="hidden-xs">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    <button type="button" class="btn btn-primary">Save changes</button>
      </div>
      <div class="hidden-sm hidden-md hidden-lg sml-footer">
    <button type="button" class="btn btn-xs btn-default" data-dismiss="modal">Close</button>
    <button type="button" class="btn btn-xs btn-primary">Save changes</button>
      </div>
  </div>

Swift3 - In a UITextView or UILabel extension, add this function:

I added some code to keep the current attributed text if you are already using attributed strings with the view (instead of overwriting them).

func setLineHeight(_ lineHeight: CGFloat) {
    guard let text = self.text, let font = self.font else { return }

    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineSpacing = 1.0
    paragraphStyle.lineHeightMultiple = lineHeight
    paragraphStyle.alignment = self.textAlignment

    var attrString:NSMutableAttributedString
    if let attributed = self.attributedText {
        attrString = NSMutableAttributedString(attributedString: attributed)
    } else {
        attrString = NSMutableAttributedString(string: text)
        attrString.addAttribute(NSFontAttributeName, value: font, range: NSMakeRange(0, attrString.length))
    }
    attrString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSMakeRange(0, attrString.length))
    self.attributedText = attrString
}

Just use <br/>. I found myself here looking for the answer to this question and then felt sort of silly for not thinking about using a simple line break as suggested by user JayKilleen in a comment.

Simply use datetime.datetime.strptime:

import datetime
stime = "01/12/2011"
print(datetime.datetime.strptime(stime, "%d/%m/%Y").timestamp())

Result:

1322697600

To use UTC instead of the local timezone use .replace:

datetime.datetime.strptime(stime, "%d/%m/%Y").replace(tzinfo=datetime.timezone.utc).timestamp()

No difference here, but it matters when you have a type that has a constructor.

struct S {
    constexpr S(int);
};

const S s0(0);
constexpr S s1(1);

s0 is a constant, but it does not promise to be initialized at compile-time. s1 is marked constexpr, so it is a constant and, because S's constructor is also marked constexpr, it will be initialized at compile-time.

Mostly this matters when initialization at runtime would be time-consuming and you want to push that work off onto the compiler, where it's also time-consuming, but doesn't slow down execution time of the compiled program

ftp4j is the best one, both for features and license:

http://www.sauronsoftware.it/projects/ftp4j/

One possible reason is because you are declaring a virtual function without defining it.

When you declare it without defining it in the same compilation unit, you're indicating that it's defined somewhere else - this means the linker phase will try to find it in one of the other compilation units (or libraries).

An example of defining the virtual function is:

virtual void fn() { /* insert code here */ }

In this case, you are attaching a definition to the declaration, which means the linker doesn't need to resolve it later.

The line

virtual void fn();

declares fn() without defining it and will cause the error message you asked about.

It's very similar to the code:

extern int i;
int *pi = &i;

which states that the integer i is declared in another compilation unit which must be resolved at link time (otherwise pi can't be set to it's address).

I use setInterval to wait for the content loaded. I hope this can help you to solve that problem.

var $audio = $('#audio');
var src = $audio.attr('src');
var a;
a = window.setInterval(function(){
    src = $audio.attr('src');
    if(src != undefined){
        window.clearInterval(a);
        $('audio').mediaelementplayer({
            audioWidth: '100%'
        });
    }
}, 0);

You could just pass an anchor tag without an href property, and use jQuery to do the required action:

<a class="foo">bar</a>

It is possible to edit same file in Split mode. It is best explained in following youtube video.

https://www.youtube.com/watch?v=q2cMEeE1aOk

You might need to convert the decimal to money (or decimal(8,2)) to get that exact formatting. The convert method can take a third parameter that controls the formatting style:

convert(varchar, cast(price as money))       12345.67
convert(varchar, cast(price as money), 0)    12345.67
convert(varchar, cast(price as money), 1)    12,345.67

Stumbled on this page as well, and then found out this is possible with just javascript (no plugins like ActiveX or Flash), but just in chrome:

https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3

Basically, they added support for a new attribute on the file input element "webkitdirectory". You can use it like this:

<input type="file" id="ctrl" webkitdirectory directory multiple/>

It allows you to select directories. The multiple attribute is a good fallback for browsers that support multiple file selection but not directory selection.

When you select a directory the files are available through the dom object for the control (document.getElementById('ctrl')), just like they are with the multiple attribute. The browsers adds all files in the selected directory to that list recursively.

You can already add the directory attribute as well in case this gets standardized at some point (couldn't find any info regarding that)

Try nodejs instead of just node

$ nodejs -v
v0.10.25

Calling erase will invalidate iterators, you could use:

void erase(std::vector<int>& myNumbers_in, int number_in)
{
    std::vector<int>::iterator iter = myNumbers_in.begin();
    while (iter != myNumbers_in.end())
    {
        if (*iter == number_in)
        {
            iter = myNumbers_in.erase(iter);
        }
        else
        {
           ++iter;
        }
    }

}

Or you could use std::remove_if together with a functor and std::vector::erase:

struct Eraser
{
    Eraser(int number_in) : number_in(number_in) {}
    int number_in;
    bool operator()(int i) const
    {
        return i == number_in;
    }
};

std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), Eraser(number_in)), myNumbers.end());

Instead of writing your own functor in this case you could use std::remove:

std::vector<int> myNumbers;
myNumbers.erase(std::remove(myNumbers.begin(), myNumbers.end(), number_in), myNumbers.end());

In C++11 you could use a lambda instead of a functor:

std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), [number_in](int number){ return number == number_in; }), myNumbers.end());

In C++17 std::experimental::erase and std::experimental::erase_if are also available, in C++20 these are (finally) renamed to std::erase and std::erase_if (note: in Visual Studio 2019 you'll need to change your C++ language version to the latest experimental version for support):

std::vector<int> myNumbers;
std::erase_if(myNumbers, Eraser(number_in)); // or use lambda

or:

std::vector<int> myNumbers;
std::erase(myNumbers, number_in);

status tell you what to do.

Unmerged paths:
  (use "git reset HEAD <file>..." to unstage)
  (use "git add <file>..." to mark resolution)

you probably applied a stash or something else that cause a conflict.

either add, reset, or rm.

Instead of telling you how you could execute a certain command (Esc:wq), I can provide you two links that may help you with VIM:

• http://bullium.com/support/vim.html provides an HTML quick reference card
• http://tnerual.eriogerg.free.fr/vim.html provides a PDF quick reference card in several languages, optimized for print-out, fold and put on your desk drawer

However, the best way to learn Vim is not only using it for Git commits, but as a regular editor for your everyday work.

If you're not going to switch to Vim, it's nonsense to keep its commands in mind. In that case, go and set up your favourite editor to use with Git.

The best approach to this problem is first making the database column UNIQUE

ALTER TABLE table_name ADD UNIQUE KEY

THEN INSERT IGNORE INTO table_name ,the value won't be inserted if it results in a duplicate key/already exists in the table.

primes = {x for x in range(2, 101) if all(x%y for y in range(2, min(x, 11)))}

I simplified the test a bit - if all(x%y instead of if not any(not x%y

I also limited y's range; there is no point in testing for divisors > sqrt(x). So max(x) == 100 implies max(y) == 10. For x <= 10, y must also be < x.

pairs = {(x, x+2) for x in primes if x+2 in primes}

Instead of generating pairs of primes and testing them, get one and see if the corresponding higher prime exists.

In the .css try

.jumbotron {_x000D_
    background-color:red !important; _x000D_
}

Not knowing your code, it's a bit hard to answer your question, but based on all the info here, I believe the issue is you're trying to use Collections.sort passing in an object defined as Collection, and sort doesn't support that.

First question. Why is client defined so generically? Why isn't it a List, Map, Set or something a little more specific?

If client was defined as a List, Map or Set, you wouldn't have this issue, as then you'd be able to directly use Collections.sort(client).

HTH

 Toast toast=Toast.makeText(getApplicationContext(),"Hello", Toast.LENGTH_SHORT);
 toast.setGravity(Gravity.CENTER, 0, 0); // last two args are X and Y are used for setting position
 toast.setDuration(10000);//you can even use milliseconds to display toast
 toast.show();**//showing the toast is important**

Use @SessionAttributes

See the docs: Using @SessionAttributes to store model attributes in the HTTP session between requests

"Understanding Spring MVC Model And Session Attributes" also gives a very good overview of Spring MVC sessions and explains how/when @ModelAttributes are transferred into the session (if the controller is @SessionAttributes annotated).

That article also explains that it is better to use @SessionAttributes on the model instead of setting attributes directly on the HttpSession because that helps Spring MVC to be view-agnostic.

Update: The site below is no longer running because, as they say on the site:

As of January 1, 2016, no publicly trusted CA is allowed to issue a SHA-1 certificate. In addition, SHA-1 support was removed by most modern browsers and operating systems in early 2017. Any new certificate you get should automatically use a SHA-2 algorithm for its signature.

Legacy clients will continue to accept SHA-1 certificates, and it is possible to have requested a certificate on December 31, 2015 that is valid for 39 months. So, it is possible to see SHA-1 certificates in the wild that expire in early 2019.

Original answer:

You can also use https://shaaaaaaaaaaaaa.com/ - set up to make this particular task easy. The site has a text box - you type in your site domain name, click the Go button and it then tells you whether the site is using SHA1 or SHA2.

Background

It looks like you are only adding children to the first parent treeView2.Nodes[0].Nodes.Add(yourChildNode)
Depending on how you want it to behave, you need to be explicit about the parent node you wish to add the child to.
For Example, from your screenshot, if you wanted to add the child to the second node you would need:
treeView2.Nodes[1].Nodes.Add(yourChildNode)
If you want to add the children to the currently selected node, get the TreeView.SelectedNode and add the children to it.

Try TreeView to get an idea of how the class operates. Unfortunately the msdn documentation is pretty light on the code samples...

I'm missing a whole lot of safety checks here!

Something like (untested):

private void addChildNode_Click(object sender, EventArgs e) {
  TreeNode ParentNode = treeView2.SelectedNode;  // for ease of debugging!
  if (ParentNode != null) {
    ParentNode.Nodes.Add("Name Of Node");
    treeView2.ExpandAll();   // so you can see what's been added              
    treeView2.Invalidate();  // requests a redraw
  }
}

Each one is a different type execution.

• ExecuteScalar is going to be the type of query which will be returning a single value.

  An example would be returning a generated id after inserting.

  INSERT INTO my_profile (Address) VALUES ('123 Fake St.'); SELECT CAST(scope_identity() AS int)

• ExecuteReader gives you a data reader back which will allow you to read all of the columns of the results a row at a time.

  An example would be pulling profile information for one or more users.

  SELECT * FROM my_profile WHERE id = '123456'

• ExecuteNonQuery is any SQL which isn't returning values, but is actually performing some form of work like inserting deleting or modifying something.

  An example would be updating a user's profile in the database.

  UPDATE my_profile SET Address = '123 Fake St.' WHERE id = '123456'

Here is the code to make this work.

[UIView beginAnimations:@"animateText" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationDuration:1.0f];
[self.lbl setAlpha:0];
[self.lbl setText:@"New Text";
[self.lbl setAlpha:1];
[UIView commitAnimations];

I know it is been a while since this question as been asked, but I found another solution, this is what worked for me:

Pattern REMOVE_TAGS = Pattern.compile("<.+?>");
    Source source= new Source(htmlAsString);
 Matcher m = REMOVE_TAGS.matcher(sourceStep.getTextExtractor().toString());
                        String clearedHtml= m.replaceAll("");

Just for readability created library ngx-if-empty-or-has-items it will check if an object, set, map or array is not empty. Maybe it will help somebody. It has the same functionality as ngIf (then, else and 'as' syntax is supported).

arrayOrObjWithData = ['1'] || {id: 1}

<h1 *ngxIfNotEmpty="arrayOrObjWithData">
  You will see it
</h1>

 or 
 // store the result of async pipe in variable
 <h1 *ngxIfNotEmpty="arrayOrObjWithData$ | async as obj">
  {{obj.id}}
</h1>

 or

noData = [] || {}
<h1 *ngxIfHasItems="noData">
   You will NOT see it
</h1>

You are mixing mysql and mysqli

Change these lines:

$sql = mysql_query("SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysql_num_rows($sql);

to

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

target isn't valid on an input element.

In this case, though, your redirection is done by Javascript, so you could have your script open up a new window.

I think the best option in Terms of performance (or in any terms) is to Distinct using the The IEqualityComparer interface.

Although implementing each time a new comparer for each class is cumbersome and produces boilerplate code.

So here is an extension method which produces a new IEqualityComparer on the fly for any class using reflection.

Usage:

var filtered = taskList.DistinctBy(t => t.TaskExternalId).ToArray();

Extension Method Code

public static class LinqExtensions
{
    public static IEnumerable<T> DistinctBy<T, TKey>(this IEnumerable<T> items, Func<T, TKey> property)
    {
        GeneralPropertyComparer<T, TKey> comparer = new GeneralPropertyComparer<T,TKey>(property);
        return items.Distinct(comparer);
    }   
}
public class GeneralPropertyComparer<T,TKey> : IEqualityComparer<T>
{
    private Func<T, TKey> expr { get; set; }
    public GeneralPropertyComparer (Func<T, TKey> expr)
    {
        this.expr = expr;
    }
    public bool Equals(T left, T right)
    {
        var leftProp = expr.Invoke(left);
        var rightProp = expr.Invoke(right);
        if (leftProp == null && rightProp == null)
            return true;
        else if (leftProp == null ^ rightProp == null)
            return false;
        else
            return leftProp.Equals(rightProp);
    }
    public int GetHashCode(T obj)
    {
        var prop = expr.Invoke(obj);
        return (prop==null)? 0:prop.GetHashCode();
    }
}

You can use this for overwrite file

git checkout file_to_overwrite

You can do it easily like this.

String cls=student.getStudentClass();
class_spinner.setSelection(classArray.indexOf(cls),true);

As long as your program's in a sane state, you can also call (void)puts(your_string) to print it to stdout. Same principle applies to all functions available to the debugger, actually.

Since SHA-1 maps several byte sequences to one, you can't "decrypt" a hash, but in theory you can find collisions: strings that have the same hash.

It seems that breaking a single hash would cost about 2.7 million dollars worth of computer time currently, so your efforts are probably better spent somewhere else.

Killing the tomcat process(forcefully, kill -9 for Linux) and starting it again solves the issue. My guess is, the tomcat instance doesn't get killed properly using shutdown.bat. So, we need to forcefully kill the process and start again.

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

Dim OutApp As Object, OutMail As Object, LogFile As String
Dim cell As Range, S As String, WMBody As String, lFile As Long

S = Environ("appdata") & "\Microsoft\Signatures\"
If Dir(S, vbDirectory) <> vbNullString Then S = S & Dir$(S & "*.htm") Else S = ""
S = CreateObject("Scripting.FileSystemObject").GetFile(S).OpenAsTextStream(1,  -2).ReadAll

WMBody = "<br>Hi All,<br><br>" & _
         "Last line,<br><br>" & S 'Add the Signature to end of HTML Body

Just thought I'd share how I achieve this. Not too sure if it's correct in the defining variables sense but it's small and easy to read which is what I like.

I attach WMBody to .HTMLBody within the object Outlook.Application OLE.

Hope it helps someone.

Thanks, Wes.

For general reference. There is a simpler way using the library Supercharged. Although, you can use extension methods with all solutions mentioned, you find practical user library toolkit.

"red".toColor(); // supports all web color names

Easier, right?

In my case I had to enable virtualization in the BIOS setting.

1. Restart PC
2. While you are on the 'restart' screen press any of these keys and you enter the bios settings in windows: esc, f1, f2, f3, f4, f8 or delete
3. For intel based systems:
   • press f7 (advanced mode)
   • go to advanced
   • cpa configuration
   • enable virtualization

And after all above steps, it finally works :-)

you can use data-tag in html5 and do this using this code:

<script>_x000D_
 $('#mainCat').on('change', function() {_x000D_
  var selected = $(this).val();_x000D_
  $("#expertCat option").each(function(item){_x000D_
   console.log(selected) ;  _x000D_
   var element =  $(this) ; _x000D_
   console.log(element.data("tag")) ; _x000D_
   if (element.data("tag") != selected){_x000D_
    element.hide() ; _x000D_
   }else{_x000D_
    element.show();_x000D_
   }_x000D_

date -d "yesterday" '+%Y-%m-%d'

To use this later:

date=$(date -d "yesterday" '+%Y-%m-%d')

The example creates a list of named lists in a loop.

  MyList <- list()
  for (aName in c("name1", "name2")){
    MyList[[aName]] <- list(aName)
  }
  MyList[["name1"]]
  MyList[["name2"]]

To add another list named "name3" do write:

  MyList$name3 <- list(1, 2, 3)

Boolean wraps the boolean primitive type. In JDK 5 and upwards, Oracle (or Sun before Oracle bought them) introduced autoboxing/unboxing, which essentially allows you to do this

boolean result = Boolean.TRUE;

or

Boolean result = true; 

Which essentially the compiler does,

Boolean result = Boolean.valueOf(true);

So, for your answer, it's YES.

You may also set {{ant.build.javac.target=1.5}} ant property to update default target version of task. See http://ant.apache.org/manual/javacprops.html#target

That is a Python bug between "*" and special characters.

Instead of

re.compile(r"\w*")

Try:

re.compile(r"[a-zA-Z0-9]*")

It works, however does not make the same regular expression.

This bug seems to have been fixed between 2.7.5 and 2.7.6.

Use the TRUNCATE TABLE command.

select * from my_table where my_field Like '[a-z][a-z]%'

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

For ppl who are still facing this issue, try adding s3_host as follows to the config hash

   :storage => :s3,
   :s3_credentials => {:access_key_id => access key,
   :secret_access_key => secret access key},
   :bucket => bucket name here,
   :s3_host_name => s3-us-west-1.amazonaws.com or whatever comes as per your region}.

This fixed the issue for me.

Even easier to use than /proc/self/status: /proc/self/statm. It's just a space delimited list of several statistics. I haven't been able to tell if both files are always present.

/proc/[pid]/statm

Provides information about memory usage, measured in pages. The columns are:

• size (1) total program size (same as VmSize in /proc/[pid]/status)
• resident (2) resident set size (same as VmRSS in /proc/[pid]/status)
• shared (3) number of resident shared pages (i.e., backed by a file) (same as RssFile+RssShmem in /proc/[pid]/status)
• text (4) text (code)
• lib (5) library (unused since Linux 2.6; always 0)
• data (6) data + stack
• dt (7) dirty pages (unused since Linux 2.6; always 0)

Here's a simple example:

from pathlib import Path
from resource import getpagesize

PAGESIZE = getpagesize()
PATH = Path('/proc/self/statm')


def get_resident_set_size() -> int:
    """Return the current resident set size in bytes."""
    # statm columns are: size resident shared text lib data dt
    statm = PATH.read_text()
    fields = statm.split()
    return int(fields[1]) * PAGESIZE


data = []
start_memory = get_resident_set_size()
for _ in range(10):
    data.append('X' * 100000)
    print(get_resident_set_size() - start_memory)

That produces a list that looks something like this:

0
0
368640
368640
368640
638976
638976
909312
909312
909312

You can see that it jumps by about 300,000 bytes after roughly 3 allocations of 100,000 bytes.

import os
os.path.abspath(os.path.expanduser(os.path.expandvars(PathNameString)))

Note that expanduser is necessary (on Unix) in case the given expression for the file (or directory) name and location may contain a leading ~/(the tilde refers to the user's home directory), and expandvars takes care of any other environment variables (like $HOME).

Actually, DB::connection('name')->select(..) doesnt work for me, because 'name' has to be in double quotes: "name"

Still, the select query is executed on my default connection. Still trying to figure out, how to convince Laravel to work the way it is intended: change the connection.

Edit: I figured it out. After debugging Laravels DatabaseManager it turned out my database.php (config file) (inside $this->app) was wrong. In the section "connections" I had stuff like "database" with values of the one i copied it from. In clear terms, instead of

env('DB_DATABASE', 'name')

I needed to place something like

'myNewName'

since all connections were listed with the same values for the database, username, password, etc. which of course makes little sense if I want to access at least another database name

Therefore, every time I wanted to select something from another database I always ended up in my default database

One has to ask what the point of using short tags is.

Quicker to type

MDCore said:

<?= is far more convenient than typing <?php echo

Yes, it is. You save having to type 7 characters * X times throughout your scripts.

However, when a script takes an hour, or 10 hours, or more, to design, develop, and write, how relevant is the few seconds of time not typing those 7 chars here and there for the duration of the script?

Compared to the potential for some core, or all, of you scripts not working if short tags are not turned on, or are on but an update or someone changing the ini file/server config stops them working, other potentials.

The small benefit you gain doesn't comes close to outweighing the severity of the potential problems, that is your site not working, or worse, only parts of it not working and thus a headache to resolve.

Easier to read

This depends on familiarity.
I've always seen and used <?php echo. So while <?= is not hard to read, it's not familiar to me and thus not easier to read.

And with front end/back end developer split (as with most companies) would a front end developer working on those templates be more familiar knowing <?= is equal to "PHP open tag and echo"?
I would say most would be more comfortable with the more logical one. That is, a clear PHP open tag and then what is happening "echo" - <?php echo.

Risk assessment
Issue = entire site or core scripts fail to work;

The potential of issue is very low + severity of outcome is very high = high risk

Conclusion

You save a few seconds here and there not having to type a few chars, but risk a lot for it, and also likely lose readability as a result.

Front or back end coders familiar with <?= are more likely to understand <?php echo, as they're standard PHP things - standard <?php open tag and very well known "echo".
(Even front end coders should know "echo" or they simply wont be working on any code served by a framework).

Whereas the reverse is not as likely, someone is not likely to logically deduce that the equals sign on a PHP short tag is "echo".

Since version 2.1 of the Maven Dependency Plugin, there is a dependency:get goal for this purpose. To make sure you are using the right version of the plugin, you'll need to use the "fully qualified name":

2014 While is back

Just think logical.

Look at this

for( var index = 0 , length = array.length ; index < length ; index++ ) {

 //do stuff

}

1. Need to create at least 2 variables (index,length)
2. Need to check if the index is smaller than the length
3. Need to increase the index
4. the for loop has 3 parameters

Now tell me why this should be faster than:

var length = array.length;

while( --length ) { //or length--

 //do stuff

}

1. One variable
2. No checks
3. the index is decreased (Machines prefer that)
4. while has only one parameter

I was totally confused when Chrome 28 showed that the for loop is faster than the while. This must have ben some sort of

"Uh, everyone is using the for loop, let's focus on that when developing for chrome."

But now, in 2014 the while loop is back on chrome. it's 2 times faster , on other/older browsers it was always faster.

Lately i made some new tests. Now in real world envoirement those short codes are worth nothing and jsperf can't actually execute properly the while loop, because it needs to recreate the array.length which also takes time.

you CAN'T get the actual speed of a while loop on jsperf.

you need to create your own custom function and check that with window.performance.now()

And yeah... there is no way the while loop is simply faster.

The real problem is actually the dom manipulation / rendering time / drawing time or however you wanna call it.

For example i have a canvas scene where i need to calculate the coordinates and collisions... this is done between 10-200 MicroSeconds (not milliseconds). it actually takes various milliseconds to render everything.Same as in DOM.

BUT

There is another super performant way using the for loop in some cases... for example to copy/clone an array

for(
 var i = array.length ;
 i > 0 ;
 arrayCopy[ --i ] = array[ i ] // doing stuff
);

Notice the setup of the parameters:

1. Same as in the while loop i'm using only one variable
2. Need to check if the index is bigger than 0;
3. As you can see this approach is different vs the normal for loop everyone uses, as i do stuff inside the 3th parameter and i also decrease directly inside the array.

Said that, this confirms that machines like the --

writing that i was thinking to make it a little shorter and remove some useless stuff and wrote this one using the same style:

for(
 var i = array.length ;
 i-- ;
 arrayCopy[ i ] = array[ i ] // doing stuff
);

Even if it's shorter it looks like using i one more time slows down everything. It's 1/5 slower than the previous for loop and the while one.

Note: the ; is very important after the for looo without {}

Even if i just told you that jsperf is not the best way to test scripts .. i added this 2 loops here

http://jsperf.com/caching-array-length/40

And here is another answer about performance in javascript

https://stackoverflow.com/a/21353032/2450730

This answer is to show performant ways of writing javascript. So if you can't read that, ask and you will get an answer or read a book about javascript http://www.ecma-international.org/ecma-262/5.1/

I have adapted the script from Russ Cam (thank you, Russ Cam!) to my own needs: I needed to merge any columns that had the same value, not just empty cells.

This could be useful to someone else... Here is what I have come up with:

jQuery(document).ready(function() {

   jQuery('table.tblSimpleAgenda tr').each(function() {
    var tr = this;
    var counter = 0;
    var strLookupText = '';

    jQuery('td', tr).each(function(index, value) {
      var td = jQuery(this);

      if ((td.text() == strLookupText) || (td.text() == "")) {
        counter++;
        td.prev().attr('colSpan', '' + parseInt(counter + 1,10) + '').css({textAlign : 'center'});
        td.remove();
      }
      else {
        counter = 0;
      }

      // Sets the strLookupText variable to hold the current value. The next time in the loop the system will check the current value against the previous value.
      strLookupText = td.text();

    });

  });

});

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

This post is old enough that this answer will probably be little use to the OP, but I spent forever trying to answer this same question, so I thought I would update it with my findings.

This answer assumes that you already have a working SQL query in place in your Excel document. There are plenty of tutorials to show you how to accomplish this on the web, and plenty that explain how to add a parameterized query to one, except that none seem to work for an existing, OLE DB query.

So, if you, like me, got handed a legacy Excel document with a working query, but the user wants to be able to filter the results based on one of the database fields, and if you, like me, are neither an Excel nor a SQL guru, this might be able to help you out.

Most web responses to this question seem to say that you should add a “?” in your query to get Excel to prompt you for a custom parameter, or place the prompt or the cell reference in [brackets] where the parameter should be. This may work for an ODBC query, but it does not seem to work for an OLE DB, returning “No value given for one or more required parameters” in the former instance, and “Invalid column name ‘xxxx’” or “Unknown object ‘xxxx’” in the latter two. Similarly, using the mythical “Parameters…” or “Edit Query…” buttons is also not an option as they seem to be permanently greyed out in this instance. (For reference, I am using Excel 2010, but with an Excel 97-2003 Workbook (*.xls))

What we can do, however, is add a parameter cell and a button with a simple routine to programmatically update our query text.

First, add a row above your external data table (or wherever) where you can put a parameter prompt next to an empty cell and a button (Developer->Insert->Button (Form Control) – You may need to enable the Developer tab, but you can find out how to do that elsewhere), like so:

Next, select a cell in the External Data (blue) area, then open Data->Refresh All (dropdown)->Connection Properties… to look at your query. The code in the next section assumes that you already have a parameter in your query (Connection Properties->Definition->Command Text) in the form “WHERE (DB_TABLE_NAME.Field_Name = ‘Default Query Parameter')” (including the parentheses). Clearly “DB_TABLE_NAME.Field_Name” and “Default Query Parameter” will need to be different in your code, based on the database table name, database value field (column) name, and some default value to search for when the document is opened (if you have auto-refresh set). Make note of the “DB_TABLE_NAME.Field_Name” value as you will need it in the next section, along with the “Connection name” of your query, which can be found at the top of the dialog.

Close the Connection Properties, and hit Alt+F11 to open the VBA editor. If you are not on it already, right click on the name of the sheet containing your button in the “Project” window, and select “View Code”. Paste the following code into the code window (copying is recommended, as the single/double quotes are dicey and necessary).

Sub RefreshQuery()
 Dim queryPreText As String
 Dim queryPostText As String
 Dim valueToFilter As String
 Dim paramPosition As Integer
 valueToFilter = "DB_TABLE_NAME.Field_Name ="

 With ActiveWorkbook.Connections("Connection name").OLEDBConnection
     queryPreText = .CommandText
     paramPosition = InStr(queryPreText, valueToFilter) + Len(valueToFilter) - 1
     queryPreText = Left(queryPreText, paramPosition)
     queryPostText = .CommandText
     queryPostText = Right(queryPostText, Len(queryPostText) - paramPosition)
     queryPostText = Right(queryPostText, Len(queryPostText) - InStr(queryPostText, ")") + 1)
     .CommandText = queryPreText & " '" & Range("Cell reference").Value & "'" & queryPostText
 End With
 ActiveWorkbook.Connections("Connection name").Refresh
End Sub

Replace “DB_TABLE_NAME.Field_Name” and "Connection name" (in two locations) with your values (the double quotes and the space and equals sign need to be included).

Replace "Cell reference" with the cell where your parameter will go (the empty cell from the beginning) - mine was the second cell in the first row, so I put “B1” (again, the double quotes are necessary).

Save and close the VBA editor.

Enter your parameter in the appropriate cell.

Right click your button to assign the RefreshQuery sub as the macro, then click your button. The query should update and display the right data!

Notes: Using the entire filter parameter name ("DB_TABLE_NAME.Field_Name =") is only necessary if you have joins or other occurrences of equals signs in your query, otherwise just an equals sign would be sufficient, and the Len() calculation would be superfluous. If your parameter is contained in a field that is also being used to join tables, you will need to change the "paramPosition = InStr(queryPreText, valueToFilter) + Len(valueToFilter) - 1" line in the code to "paramPosition = InStr(Right(.CommandText, Len(.CommandText) - InStrRev(.CommandText, "WHERE")), valueToFilter) + Len(valueToFilter) - 1 + InStr(.CommandText, "WHERE")" so that it only looks for the valueToFilter after the "WHERE".

This answer was created with the aid of datapig’s “BaconBits” where I found the base code for the query update.

@Andy's answer is Okay. But if you want to show time without 24 hours format then you may follow like this way

string dateTime = DateTime.Now.ToString("hh:mm:ss tt", CultureInfo.InvariantCulture);

After that, you should get time like as "10:35:20 PM" or "10:35:20 AM"

Kotlin Solution

view.isVisible = true
view.isInvisible = true
view.isGone = true

// For these to work, you need to use androidx and import:
import androidx.core.view.isVisible // or isInvisible/isGone

Kotlin Extension Solution

If you'd like them to be more consistent length, work for nullable views, and lower the chance of writing the wrong boolean, try using these custom extensions:

// Example
view.hide()

fun View?.show() {
    if (this == null) return
    if (!isVisible) isVisible = true
}

fun View?.hide() {
    if (this == null) return
    if (!isInvisible) isInvisible = true
}

fun View?.gone() {
    if (this == null) return
    if (!isGone) isGone = true
}

To make conditional visibility simple, also add these:

fun View?.show(visible: Boolean) {
    if (visible) show() else gone()
}

fun View?.hide(hide: Boolean) {
    if (hide) hide() else show()
}

fun View?.gone(gone: Boolean = true) {
    if (gone) gone() else show()
}

None of the other answers worked for me. For me the device registered with eclipse after I rebooted the phone. Process for that is going to vary by phone model.

if you try with lubridate:

library(lubridate)
lubridate::week(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))

[1] 11 11 12  1

The pattern is the same. Try isoweek

lubridate::isoweek(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))
[1] 11 12 12  1

new table inherits only "not null" constraint and no other constraint. Thus you can alter the table after creating it with "create table as" command or you can define all constraint that you need by following the

create table t1 (id number default 1 not null);
insert into t1 (id) values (2);

create table t2 as select * from t1;

This will create table t2 with not null constraint. But for some other constraint except "not null" you should use the following syntax

create table t1 (id number default 1 unique);
insert into t1 (id) values (2);

create table t2 (id default 1 unique)
as select * from t1;

This might help

def union(a,b):
    for e in b:
        if e not in a:
            a.append(e)

The union function merges the second list into first, with out duplicating an element of a, if it's already in a. Similar to set union operator. This function does not change b. If a=[1,2,3] b=[2,3,4]. After union(a,b) makes a=[1,2,3,4] and b=[2,3,4]

we developed a module on GitHub that has hooks for fetching data so you can use it like this for your purpose:

import { useFetching } from "react-concurrent";

const app = () => {
  const { data, isLoading, error , refetch } = useFetching(() =>
    fetch("http://example.com"),
  );
};

You can fork that out, but any PRs are welcome. https://github.com/hosseinmd/react-concurrent#react-concurrent

Remember that, as described in "Git: Finding what branch a commit came from", you cannot easily pinpoint the branch where that commit has been made (branches can be renamed, moved, deleted...), even though git branch --contains <commit> is a start.

• You can go back from commit to commit until git branch --contains <commit> doesn't list the feature branch and list develop branch,
• compare that commit SHA1 to /refs/heads/develop

If the two commits id match, you are good to go (that would mean the feature branch has its origin at the HEAD of develop).

TEXT is used for large pieces of string data. If the length of the field exceeed a certain threshold, the text is stored out of row.

VARCHAR is always stored in row and has a limit of 8000 characters. If you try to create a VARCHAR(x), where x > 8000, you get an error:

Server: Msg 131, Level 15, State 3, Line 1

The size () given to the type ‘varchar’ exceeds the maximum allowed for any data type (8000)

These length limitations do not concern VARCHAR(MAX) in SQL Server 2005, which may be stored out of row, just like TEXT.

Note that MAX is not a kind of constant here, VARCHAR and VARCHAR(MAX) are very different types, the latter being very close to TEXT.

In prior versions of SQL Server you could not access the TEXT directly, you only could get a TEXTPTR and use it in READTEXT and WRITETEXT functions.

In SQL Server 2005 you can directly access TEXT columns (though you still need an explicit cast to VARCHAR to assign a value for them).

TEXT is good:

• If you need to store large texts in your database
• If you do not search on the value of the column
• If you select this column rarely and do not join on it.

VARCHAR is good:

• If you store little strings
• If you search on the string value
• If you always select it or use it in joins.

By selecting here I mean issuing any queries that return the value of the column.

By searching here I mean issuing any queries whose result depends on the value of the TEXT or VARCHAR column. This includes using it in any JOIN or WHERE condition.

As the TEXT is stored out of row, the queries not involving the TEXT column are usually faster.

Some examples of what TEXT is good for:

• Blog comments
• Wiki pages
• Code source

Some examples of what VARCHAR is good for:

• Usernames
• Page titles
• Filenames

As a rule of thumb, if you ever need you text value to exceed 200 characters AND do not use join on this column, use TEXT.

Otherwise use VARCHAR.

P.S. The same applies to UNICODE enabled NTEXT and NVARCHAR as well, which you should use for examples above.

P.P.S. The same applies to VARCHAR(MAX) and NVARCHAR(MAX) that SQL Server 2005+ uses instead of TEXT and NTEXT. You'll need to enable large value types out of row for them with sp_tableoption if you want them to be always stored out of row.

As mentioned above and here, TEXT is going to be deprecated in future releases:

The text in row option will be removed in a future version of SQL Server. Avoid using this option in new development work, and plan to modify applications that currently use text in row. We recommend that you store large data by using the varchar(max), nvarchar(max), or varbinary(max) data types. To control in-row and out-of-row behavior of these data types, use the large value types out of row option.

The except:pass construct essentially silences any and all exceptional conditions that come up while the code covered in the try: block is being run.

What makes this bad practice is that it usually isn't what you really want. More often, some specific condition is coming up that you want to silence, and except:pass is too much of a blunt instrument. It will get the job done, but it will also mask other error conditions that you likely haven't anticipated, but may very well want to deal with in some other way.

What makes this particularly important in Python is that by the idioms of this language, exceptions are not necessarily errors. They're often used this way, of course, just as in most languages. But Python in particular has occasionally used them to implement an alternative exit path from some code tasks which isn't really part of the normal running case, but is still known to come up from time to time and may even be expected in most cases. SystemExit has already been mentioned as an old example, but the most common example nowadays may be StopIteration. Using exceptions this way caused a lot of controversy, especially when iterators and generators were first introduced to Python, but eventually the idea prevailed.

This lists all the files (and only the files) in the current directory:

for /r %i in (*) do echo %i

Also if you run that command in a batch file you need to double the % signs.

for /r %%i in (*) do echo %%i

(thanks @agnul)

<?php
$divStyle=''; // show div

// add condition
if($variable == '1'){
  $divStyle='style="display:none;"'; //hide div
}

print'<div '.$divStyle.'>Div to hide</div>';
?>

To expand this question into the realm of use outside of Excel s own VBA, the ActiveWindow property must be addressed as a child of the Excel.Application object.

Example for creating an Excel workbook from Access:

Using the Excel.Application object in another Office application's VBA project will require you to add Microsoft Excel 15.0 Object library (or equivalent for your own version).

Option Explicit

Sub xls_Build__Report()
    Dim xlApp As Excel.Application, ws As Worksheet, wb As Workbook
    Dim fn As String

    Set xlApp = CreateObject("Excel.Application")
    xlApp.DisplayAlerts = False
    xlApp.Visible = True

    Set wb = xlApp.Workbooks.Add
    With wb
        .Sheets(1).Name = "Report"
        With .Sheets("Report")

            'report generation here

        End With

        'This is where the Freeze Pane is dealt with
        'Freezes top row
        With xlApp.ActiveWindow
            .SplitColumn = 0
            .SplitRow = 1
            .FreezePanes = True
        End With

        fn = CurrentProject.Path & "\Reports\Report_" & Format(Date, "yyyymmdd") & ".xlsx"
        If CBool(Len(Dir(fn, vbNormal))) Then Kill fn
        .SaveAs FileName:=fn, FileFormat:=xlOpenXMLWorkbook
    End With

Close_and_Quit:
    wb.Close False
    xlApp.Quit
End Sub

The core process is really just a reiteration of previously submitted answers but I thought it was important to demonstrate how to deal with ActiveWindow when you are not within Excel's own VBA. While the code here is VBA, it should be directly transcribable to other languages and platforms.

There's no goto instruction in the Python programming language. You'll have to write your code in a structured way... But really, why do you want to use a goto? that's been considered harmful for decades, and any program you can think of can be written without using goto.

Of course, there are some cases where an unconditional jump might be useful, but it's never mandatory, there will always exist a semantically equivalent, structured solution that doesn't need goto.

My personal preference is to delete the branch name after I’m done with a topic branch.

Instead of trying to use the branch name to explain the meaning of the branch, I start the subject line of the commit message in the first commit on that branch with “Branch:” and include further explanations in the body of the message if the subject does not give me enough space.

The branch name in my use is purely a handle for referring to a topic branch while working on it. Once work on the topic branch has concluded, I get rid of the branch name, sometimes tagging the commit for later reference.

That makes the output of git branch more useful as well: it only lists long-lived branches and active topic branches, not all branches ever.

Along the same lines as some of the suggestions you would need to do at least the following:

• Load some CSS dynamically through JavaScript
• Craft some print-specific CSS rules
• Apply your fancy CSS rules through JavaScript

An example CSS could be as simple as this:

@media print {
  body * {
    display:none;
  }

  body .printable {
    display:block;
  }
}

Your JavaScript would then only need to apply the "printable" class to your target div and it will be the only thing visible (as long as there are no other conflicting CSS rules -- a separate exercise) when printing happens.

<script type="text/javascript">
  function divPrint() {
    // Some logic determines which div should be printed...
    // This example uses div3.
    $("#div3").addClass("printable");
    window.print();
  }

You may want to optionally remove the class from the target after printing has occurred, and / or remove the dynamically-added CSS after printing has occurred.

Below is a full working example, the only difference is that the print CSS is not loaded dynamically. If you want it to really be unobtrusive then you will need to load the CSS dynamically like in this answer.

Do you mean like this?

<!-- ... --->
<td>
   this text should be left justified
   and this text should be right justified?
</td>
<!-- ... --->

If yes

<!-- ... --->
<td>
   <p style="text-align: left;">this text should be left justified</p>
   <p style="text-align: right;">and this text should be right justified?</p>
</td>
<!-- ... --->

does not work if numberOfLines > 1 What i did made a condition like this-

if(lblRecLocation.text.length > 100)
    lblRecLocation.font = [UIFont fontWithName:@"app_font_name" size:10];

Without jQuery:

document.getElementById('file').onchange = function(){

  var file = this.files[0];

  var reader = new FileReader();
  reader.onload = function(progressEvent){
    // Entire file
    console.log(this.result);

    // By lines
    var lines = this.result.split('\n');
    for(var line = 0; line < lines.length; line++){
      console.log(lines[line]);
    }
  };
  reader.readAsText(file);
};

HTML:

<input type="file" name="file" id="file">

Remember to put your javascript code after the file field is rendered.

I adopted the solution suggested by @(Kirk Woll), and it works for me. I have also seen in the Android source code for the "Contacts" app, that they use a similar technique. I would like to add some more details: On top on my ListActivity-derived class:

private static final String LIST_STATE = "listState";
private Parcelable mListState = null;

Then, some method overrides:

@Override
protected void onRestoreInstanceState(Bundle state) {
    super.onRestoreInstanceState(state);
    mListState = state.getParcelable(LIST_STATE);
}

@Override
protected void onResume() {
    super.onResume();
    loadData();
    if (mListState != null)
        getListView().onRestoreInstanceState(mListState);
    mListState = null;
}

@Override
protected void onSaveInstanceState(Bundle state) {
    super.onSaveInstanceState(state);
    mListState = getListView().onSaveInstanceState();
    state.putParcelable(LIST_STATE, mListState);
}

Of course "loadData" is my function to retrieve data from the DB and put it onto the list.

On my Froyo device, this works both when you change the phone orientation, and when you edit an item and go back to the list.

You can try styling with LevelSubMenuStyles

            <asp:Menu ID="mainMenu" runat="server" Orientation="Horizontal" 
                StaticEnableDefaultPopOutImage="False">
                <StaticMenuStyle CssClass="test" />
                <LevelSubMenuStyles>
                    <asp:SubMenuStyle BackColor="#33CCFF" BorderColor="#FF9999" 
                        Font-Underline="False" />
                    <asp:SubMenuStyle BackColor="#FF99FF" Font-Underline="False" />
                </LevelSubMenuStyles>
                <StaticMenuItemStyle CssClass="main-nav-item" />
            </asp:Menu>

Well, there could be many solutions to this problem like scraping the version code from App Page (Google Play App page), etc.

But I am going to show you the ultimate solution that won't cost a penny and will work like magic.

1. Just save the latest Version code of your app on Firebase Remote
   Config panel
2. Fetch that version code value whenever the app is opened

3. Compare it with the current version code of the app, which you can get by the following code

   private int getCurrentVersionCode() {
   try {
       return getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
   } catch (NameNotFoundException e) {
       e.printStackTrace();
   }
   return -1;
   

   }

If the fetched version code is greater than the current version, show an AlertDialog asking to update the app. Otherwise, the app is already updated.

So, whenever you roll out the new version, you need to put that new version code in Firebase Remote config panel

You can read the whole tutorial on how to force users to update the app using Firebase Remote Config

In my case, the solution was to close Android Studio and kill the java processs, which was very big (1.2 GB). After this, my project runs normally (OS X Mount Lion, Android Studio 1.2.2, iMac Mid 2011 4GB Ram).

2 from decimal numbering system in binary is as follows

10

now if you do

2 << 11

it would be , 11 zeros would be padded on the right side

1000000000000

The signed left shift operator "<<" shifts a bit pattern to the left, and the signed right shift operator ">>" shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator ">>>" shifts a zero into the leftmost position, while the leftmost position after ">>" depends on sign extension [..]

left shifting results in multiplication by 2 (*2) in terms or arithmetic

For example

2 in binary 10, if you do <<1 that would be 100 which is 4

4 in binary 100, if you do <<1 that would be 1000 which is 8

In addition to Ishmaeel's answer, the method OpenMappedMachineConfiguration() will always return a Configuration object. So to check to see if it loaded you should check the HasFile property where true means it came from a file.

The error message says

"The path to the driver executable must be set by the webdriver.ie.driver system property;"

You are setting the path for the Chrome Driver with "webdriver.chrome.driver" property. You are not setting the file location when for InternetExplorerDriver, to do that you must set "webdriver.ie.driver" property.

You can set these properties in your shell, via maven, or your IDE with the -DpropertyName=Value

-Dwebdriver.ie.driver="C:/.../IEDriverServer.exe" 

You need to use quotes because of spaces or slashes in your path on windows machines, or alternatively reverse the slashes other wise they are the string string escape prefix.

You could also use

System.setProperty("webdriver.ie.driver","C:/.../IEDriverServer.exe"); 

inside your code.

First you need an object

public class MyObject {
  public string Id {get;set;}
  public string Text {get;set;}
  ...
}

Then in here

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

        using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
            JavaScriptSerializer js = new JavaScriptSerializer();
            var objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
        }

    }

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

JavaScriptSerializer System.Web.Script.Serialization

First, here's some sample data:

set.seed(1)
dat <- data.frame(one = rnorm(15),
                 two = sample(LETTERS, 15),
                 three = rnorm(15),
                 four = runif(15))
dat <- data.frame(lapply(dat, function(x) { x[sample(15, 5)] <- NA; x }))
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677        NA
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA        NA
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Here's our replacement:

dat[["four"]][is.na(dat[["four"]])] <- 0
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677 0.0000000
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA 0.0000000
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Alternatively, you can, of course, write dat$four[is.na(dat$four)] <- 0

See How to Make Dialogs.

You can use:

JOptionPane.showMessageDialog(frame, "Eggs are not supposed to be green.");

And you can also change the symbol to an error message or an warning. E.g see JOptionPane Features.

I'm running on a system where I have sudo apt but no sudo pip. (And no su access.) I got myself into this same situation by following the advice from pip:

You are using pip version 8.1.1, however 18.0 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

None of the other fixes worked for me, because I don't have enough admin privileges. However, a few things stuck with me from reading up on this:

• I shouldn't have done this. Sure, pip told me to. It lied.
• Using --user solves a lot of issues by focusing on the user-only directory.

So, I found this command line to work to revert me back to where I was. If you were using a different version than 8.1.1, you will obviously want to change that part of the line.

python -m pip install --force-reinstall pip==8.1.1 --user

That's the only thing that worked for me, but it worked perfectly!

JAVA_HOME should point at where the JDK is installed not not a JRE.

So, if you type ls $JAVA_HOME what do you see? if you do ls $JAVA_HOME/bin/ do you see javac?

If the first doesn't work then you don't have JAVA_HOME pointing at the right directory. If the second doesn't work then you need to point JAVA_HOME at a JDK instead of a JRE.

See O'Reilly "Java Cookbook", Ian Darwin - recipe 17.4 Handling Multiple Clients.

Pay attention that accept() is not thread safe, so the call is wrapped within synchronized.

64: synchronized(servSock) {
65:     clientSocket = servSock.accept();
66: }

It worked for me, In eclipse: Window > Preference > Team > SVN: select SVNKit (Pure Java) instead JavaHL(JNI)

If you use jCanvas library you can use opacity property when drawing. If you need fade effect on top of that, simply redraw with different values.

It is possible to scaffold a view. Just use -Tables the way you would to scaffold a table, only use the name of your view. E.g., If the name of your view is ‘vw_inventory’, then run this command in the Package Manager Console (substituting your own information for "My..."):

PM> Scaffold-DbContext "Server=MyServer;Database=MyDatabase;user id=MyUserId;password=MyPassword" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Temp -Tables vw_inventory

This command will create a model file and context file in the Temp directory of your project. You can move the model file into your models directory (remember to change the namespace name). You can copy what you need from the context file and paste it into the appropriate existing context file in your project.

Note: If you want to use your view in an integration test using a local db, you'll need to create the view as part of your db setup. If you’re going to use the view in more than one test, make sure to add a check for existence of the view. In this case, since the SQL ‘Create View’ statement is required to be the only statement in the batch, you’ll need to run the create view as dynamic Sql within the existence check statement. Alternatively you could run separate ‘if exists drop view…’, then ‘create view’ statements, but if multiple tests are running concurrently, you don’t want the view to be dropped if another test is using it. Example:

  void setupDb() {
    ...
    SomeDb.Command(db => db.Database.ExecuteSqlRaw(CreateInventoryView()));
    ...
  }
  public string CreateInventoryView() => @"
  IF OBJECT_ID('[dbo].[vw_inventory]') IS NULL
    BEGIN EXEC('CREATE VIEW [dbo].[vw_inventory] AS
       SELECT ...')
    END";

You should definitely consider using a package like @Shubham above is advising, but I created a working codepen based on what you described: http://codepen.io/dtschust/pen/WGwdVN?editors=1111 . It works in my browser in chrome, perhaps you can see if there's something I did there that you missed, or if there's some extended complexity in your application that prevents this from working.

Don't use a function that loops to split a string!, my function below will split a string very fast, with no looping!

Before you use my function, you need to set up a "helper" table, you only need to do this one time per database:

CREATE TABLE Numbers
(Number int  NOT NULL,
    CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
DECLARE @x int
SET @x=0
WHILE @x<8000
BEGIN
    SET @x=@x+1
    INSERT INTO Numbers VALUES (@x)
END

use this function to split your string, which does not loop and is very fast:

CREATE FUNCTION [dbo].[FN_ListToTable]
(
     @SplitOn              char(1)              --REQUIRED, the character to split the @List string on
    ,@List                 varchar(8000)        --REQUIRED, the list to split apart
)
RETURNS
@ParsedList table
(
    ListValue varchar(500)
)
AS
BEGIN

/**
Takes the given @List string and splits it apart based on the given @SplitOn character.
A table is returned, one row per split item, with a column name "ListValue".
This function workes for fixed or variable lenght items.
Empty and null items will not be included in the results set.


Returns a table, one row per item in the list, with a column name "ListValue"

EXAMPLE:
----------
SELECT * FROM dbo.FN_ListToTable(',','1,12,123,1234,54321,6,A,*,|||,,,,B')

    returns:
        ListValue  
        -----------
        1
        12
        123
        1234
        54321
        6
        A
        *
        |||
        B

        (10 row(s) affected)

**/



----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
INSERT INTO @ParsedList
        (ListValue)
    SELECT
        ListValue
        FROM (SELECT
                  LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(@SplitOn, List2, number+1)-number - 1))) AS ListValue
                  FROM (
                           SELECT @SplitOn + @List + @SplitOn AS List2
                       ) AS dt
                      INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
                  WHERE SUBSTRING(List2, number, 1) = @SplitOn
             ) dt2
        WHERE ListValue IS NOT NULL AND ListValue!=''



RETURN

END --Function FN_ListToTable

you can use this function as a table in a join:

SELECT
    Col1, COl2, Col3...
    FROM  YourTable
        INNER JOIN FN_ListToTable(',',@YourString) s ON  YourTable.ID = s.ListValue

Here is your example:

Select * from sometable where tableid in(SELECT ListValue FROM dbo.FN_ListToTable(',',@Ids) s)

I hope this doesn't count as spam. I humbly ended up writing a function after endless debug sessions: http://github.com/halilim/Javascript-Simple-Object-Inspect

function simpleObjInspect(oObj, key, tabLvl)
{
    key = key || "";
    tabLvl = tabLvl || 1;
    var tabs = "";
    for(var i = 1; i < tabLvl; i++){
        tabs += "\t";
    }
    var keyTypeStr = " (" + typeof key + ")";
    if (tabLvl == 1) {
        keyTypeStr = "(self)";
    }
    var s = tabs + key + keyTypeStr + " : ";
    if (typeof oObj == "object" && oObj !== null) {
        s += typeof oObj + "\n";
        for (var k in oObj) {
            if (oObj.hasOwnProperty(k)) {
                s += simpleObjInspect(oObj[k], k, tabLvl + 1);
            }
        }
    } else {
        s += "" + oObj + " (" + typeof oObj + ") \n";
    }
    return s;
}

Usage

alert(simpleObjInspect(anyObject));

or

console.log(simpleObjInspect(anyObject));

Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global, nonlocal, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.

Here are some examples regarding global:-

>>> global_var = 5
>>> def fn():
...     print(global_var)
... 
>>> fn()
5
>>> def fn_2():
...     global_var += 2
...     print(global_var)
... 
>>> fn_2()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
...     global global_var
...     global_var += 2
...     print(global_var)
... 
>>> fn_3()
7

The same patterns can be applied to nonlocal variables too, but this keyword is only available to the latter Python versions.

In case you're wondering, nonlocal is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def within a def, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...

Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner defs using the same variable names as the outer ones, which just should just be avoided to be honest.

Implement the View.OnClickListener interface and override the onClick method.

ImageView btnSearch;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search1);
        ImageView btnSearch = (ImageView) findViewById(R.id.btnSearch);
        btnSearch.setOnClickListener(this);
    }

@Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btnSearch: {
                Intent intent = new Intent(Search.this,SearchFeedActivity.class);
                startActivity(intent);
                break;
            }

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

"TypeScript Fundamentals" -- a Pluralsight video-course by Dan Wahlin and John Papa is a really good, presently (March 25, 2016) updated to reflect TypeScript 1.8, introduction to Typescript.

For me the really good features, beside the nice possibilities for intellisense, are the classes, interfaces, modules, the ease of implementing AMD, and the possibility to use the Visual Studio Typescript debugger when invoked with IE.

To summarize: If used as intended, Typescript can make JavaScript programming more reliable, and easier. It can increase the productivity of the JavaScript programmer significantly over the full SDLC.

try this, it works. (in the example below i have 3 cells for example.)

    func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
    let visibleRect = CGRect(origin: self.collectionView.contentOffset, size: self.collectionView.bounds.size)
    let visiblePoint = CGPointMake(CGRectGetMidX(visibleRect), CGRectGetMidY(visibleRect))
    let visibleIndexPath = self.collectionView.indexPathForItemAtPoint(visiblePoint)
    if let v = visibleIndexPath {
        switch v.item {
        case 0: setImageDescription()
            break
        case 1: setImageConditions()
            break
        case 2: setImageResults()
            break
        default: break
        }
    }

lsof -n -i | awk '{ print $1,$9; }' | sort -u

This displays who's doing what. Remove -n to see hostnames (a bit slower).

In your case $("#mySelect").val("fg") :)

import codecs
f=codecs.open("test.html", 'r')
print f.read()

Try something like this.

A version I do not believe that has been posted yet. I tested with python 2.7 on Ubuntu 12.04.

Found this solution at : http://code.activestate.com/recipes/439094-get-the-ip-address-associated-with-a-network-inter/

import socket
import fcntl
import struct

def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,  # SIOCGIFADDR
        struct.pack('256s', ifname[:15])
    )[20:24])

Example Result:

>>> get_ip_address('eth0')
'38.113.228.130'

It´s out of the scope of the question, but I think it might be also interesting to know how to link to a route. The query would look like this:

https://www.google.es/maps/dir/'52.51758801683297,13.397978515625027'/'52.49083837044266,13.369826049804715'

Instead of JSONObject , you can use ObjectMapper to convert java object to json string

ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);

I had the same problems. I had to change file rights. Unmark "read only" in their properties.

Two more ways to do it (see my comment on the previous answer by @Tomasz Nurkiewicz):

The first relies on the fact that the compiler simply won't let you pass in something of the wrong type:

when(a.method(any(Class.class))).thenReturn(b);

You lose the exact typing (the Class<? extends A>) but it probably works as you need it to.

The second is a lot more involved but is arguably a better solution if you really want to be sure that the argument to method() is an A or a subclass of A:

when(a.method(Matchers.argThat(new ClassOrSubclassMatcher<A>(A.class)))).thenReturn(b);

Where ClassOrSubclassMatcher is an org.hamcrest.BaseMatcher defined as:

public class ClassOrSubclassMatcher<T> extends BaseMatcher<Class<T>> {

    private final Class<T> targetClass;

    public ClassOrSubclassMatcher(Class<T> targetClass) {
        this.targetClass = targetClass;
    }

    @SuppressWarnings("unchecked")
    public boolean matches(Object obj) {
        if (obj != null) {
            if (obj instanceof Class) {
                return targetClass.isAssignableFrom((Class<T>) obj);
            }
        }
        return false;
    }

    public void describeTo(Description desc) {
        desc.appendText("Matches a class or subclass");
    }       
}

Phew! I'd go with the first option until you really need to get finer control over what method() actually returns :-)

I had the same problem but now here is how I solved it
Go to https://developers.facebook.com/
• Click on the Apps menu on the top bar.
• Select the respective app from the drop down.
• Click Settings from the table in the left side of the page
• Then under the Contact Email type in your email you would like to use
• Then click save settings button
• Go to 'Status & Review' from the table in the left side of the page.
• Do you want to make this app and all its live features available to the general public? - Select switch to set YES/NO value.

There is no good way to do that, but you should use portable solution, so avoid system() calls, in your case you could use cin.get() or getch() as you mentioned in your question, also there is one advice. Make all pauses controlled by one (or very few) preprocessor definitions.

For example:

Somewhere in global file:

#define USE_PAUSES
#ifndef _DEBUG    //I asume you have _DEBUG definition for debug and don't have it for release build
#undef USE_PAUSES
#endif

Somewhere in code

#ifdef USE_PAUSES
cin.get();
#endif

This is not universal advice, but you should protect yourself from putting pauses in release builds and these should have easy control, my mentioned global file may not be so global, because changes in that may cause really long compilation.

Spinning off the closing question, "how do I convert a to type Test::A" rather than being rigid about the requirement to have a cast in there, and answering several years late only because this seems to be a popular question and nobody else has mentioned the alternative, per the C++11 standard:

5.2.9 Static cast

... an expression e can be explicitly converted to a type T using a static_cast of the form static_cast<T>(e) if the declaration T t(e); is well-formed, for some invented temporary variable t (8.5). The effect of such an explicit conversion is the same as performing the declaration and initialization and then using the temporary variable as the result of the conversion.

Therefore directly using the form t(e) will also work, and you might prefer it for neatness:

auto result = Test(a);

You can also use PowerShell to quickly replace words or character reptitions. PowerShell is for Windows. Current version is 3.0.

$oldfile = "$env:windir\WindowsUpdate.log"

$newfile = "$env:temp\newfile.txt"
$text = (Get-Content -Path $oldfile -ReadCount 0) -join "`n"

$text -replace '/(.)\1{9,}/', ' ' | Set-Content -Path $newfile

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

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

You can check the return value from scanf. This code will just sit there until it receives a string.

int a;

do {
  // other code
  a = scanf("%s", url);

} while (a <= 0);

Add ?var1=data1&var2=data2 to the end of url to submit values to the page via GET:

using System.Net;
using System.IO;

string url = "https://www.example.com/scriptname.php?var1=hello";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();

Reported by @davidpbr ConstraintLayout performance

I made two similar 7-child layouts, one each with a parent ConstraintLayout and RelativeLayout. Based on Android Studio method tracing tool, it appears the ConstraintLayout spends more time in onMeasure and performs additional work in onFinishInflate.

Library used (support-v4, appcompat-v7…):

com.android.support.constraint:constraint-layout:1.0.0-alpha1

Devices/Android versions reproduced on: Samsung Galaxy S6 (SM-G920A. Sorry, no Nexus atm). Android 5.0.2

Handling categorical features scikit-learn expects all features to be numeric. So how do we include a categorical feature in our model?

Ordered categories: transform them to sensible numeric values (example: small=1, medium=2, large=3) Unordered categories: use dummy encoding (0/1) What are the categorical features in our dataset?

Ordered categories: weather (already encoded with sensible numeric values) Unordered categories: season (needs dummy encoding), holiday (already dummy encoded), workingday (already dummy encoded) For season, we can't simply leave the encoding as 1 = spring, 2 = summer, 3 = fall, and 4 = winter, because that would imply an ordered relationship. Instead, we create multiple dummy variables:

# An utility function to create dummy variable
`def create_dummies( df, colname ):
col_dummies = pd.get_dummies(df[colname], prefix=colname)
col_dummies.drop(col_dummies.columns[0], axis=1, inplace=True)
df = pd.concat([df, col_dummies], axis=1)
df.drop( colname, axis = 1, inplace = True )
return df`

The TextBox wasn't receiving the enter key at all in my situation. The first thing I tried was changing the enter key into an input key, but I was still getting the system beep when enter was pressed. So, I subclassed and overrode the ProcessDialogKey() method and sent my own event that I could bind the click handler to.

public class EnterTextBox : TextBox
{
    [Browsable(true), EditorBrowsable]
    public event EventHandler EnterKeyPressed;

    protected override bool ProcessDialogKey(Keys keyData)
    {
        if (keyData == Keys.Enter)
        {
            EnterKeyPressed?.Invoke(this, EventArgs.Empty);
            return true;
        }
        return base.ProcessDialogKey(keyData);
    }
}

Attribute_Brands is a named range.

On any worksheet (tab) press F5 and type Attribute_Brands into the reference box and click on the OK button.

This will take you to the named range.

The data in it can be updated by typing new values into the cells.

The named range can be altered via the 'Insert - Name - Define' menu.

If you support IE, for versions of Internet Explorer 8 and above, this:

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />

Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.

If you separate with semi-colon, it sets compatibility levels for different versions. For example:

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

For this:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

It forces the browser the render at whatever the most recent version's standards are.

If path is not hardcoded in any script then your websites should work seamlessly.

Make sure you somehow use results which are computed in benchmarked code. Otherwise your code can be optimized away.

I wrote an updated version of Kees C. Bakker's answer:

const hasVerticalScroll = (node) => {
  if (!node) {
    if (window.innerHeight) {
      return document.body.offsetHeight > window.innerHeight
    }
    return (document.documentElement.scrollHeight > document.documentElement.offsetHeight)
      || (document.body.scrollHeight > document.body.offsetHeight)
  }
  return node.scrollHeight > node.offsetHeight
}

if (hasVerticalScroll(document.querySelector('body'))) {
  this.props.handleDisableDownScrollerButton()
}

The function returns true or false depending whether the page has a vertical scrollbar or not.

For example:

const hasVScroll = hasVerticalScroll(document.querySelector('body'))

if (hasVScroll) {
  console.log('HAS SCROLL', hasVScroll)
}

Here's a somewhat robust way to get the path to Chrome.

(Note that you should do this only if you specifically need Chrome, and not the default browser, or Chromium, or something else.)

def try_find_chrome_path():
    result = None
    if _winreg:
        for subkey in ['ChromeHTML\\shell\\open\\command', 'Applications\\chrome.exe\\shell\\open\\command']:
            try: result = _winreg.QueryValue(_winreg.HKEY_CLASSES_ROOT, subkey)
            except WindowsError: pass
            if result is not None:
                result_split = shlex.split(result, False, True)
                result = result_split[0] if result_split else None
                if os.path.isfile(result):
                    break
                result = None
    else:
        expected = "google-chrome" + (".exe" if os.name == 'nt' else "")
        for parent in os.environ.get('PATH', '').split(os.pathsep):
            path = os.path.join(parent, expected)
            if os.path.isfile(path):
                result = path
                break
    return result

When you upload a file using FileField, the file will have a URL that you can use to point to the file and use HTML download attribute to download that file you can simply do this.

models.py

The model.py looks like this

class CsvFile(models.Model):
    csv_file = models.FileField(upload_to='documents')

views.py

#csv upload

class CsvUploadView(generic.CreateView):

   model = CsvFile
   fields = ['csv_file']
   template_name = 'upload.html'

#csv download

class CsvDownloadView(generic.ListView):

    model = CsvFile
    fields = ['csv_file']
    template_name = 'download.html'

Then in your templates.

#Upload template

upload.html

<div class="container">
<form action="#" method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.media }}
    {{ form.as_p }}
    <button class="btn btn-primary btn-sm" type="submit">Upload</button>
</form>

#download template

download.html

  {% for document in object_list %}

     <a href="{{ document.csv_file.url }}" download  class="btn btn-dark float-right">Download</a>

  {% endfor %}

I did not use forms, just rendered model but either way, FileField is there and it will work the same.

My issue on OSX it was gradle version. Gradle was ignoring my Android.mk. So, in order to override this option, and use my make instead, I have entered this line:

sourceSets.main.jni.srcDirs = []

inside of the android tag in build.gradle.

I have wasted lot of time on this!

You could query the sys.tables database view to get out the names of the tables, and then use this query to build yourself another query to do the update on the back of that. For instance:

select 'select * from '+name from sys.tables

will give you a script that will run a select * against all the tables in the system catalog, you could alter the string in the select clause to do your update, as long as you know the column name is the same on all the tables you wish to update, so your script would look something like:

select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables

You could also then predicate on the tables query to only include tables that have a name in a certain format, or are in a subset you want to create the update script for.

No real need for the JSON.NET package. You could use JavaScriptSerializer. The Serialize method will turn a managed type instance into a JSON string.

var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(instanceOfThing);

Read up the concept of a name space. When you assign a variable in a function, you only assign it in the namespace of this function. But clearly you want to use it between all functions.

def defineAList():
    #list = ['1','2','3'] this creates a new list, named list in the current namespace.
    #same name, different list!

    list.extend['1', '2', '3', '4'] #this uses a method of the existing list, which is in an outer namespace
    print "For checking purposes: in defineAList, list is",list
    return list

Alternatively, you can pass it around:

def main():
    new_list = defineAList()
    useTheList(new_list)

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

I encountered a similar problem like this, problem was with the backend . I was using node server(Express). I had a get request from the frontend(angular) as shown below

   onGetUser(){
        return this.http.get("http://localhost:3000/user").pipe(map(
            (response:Response)=>{
                const user =response.json();
                return user;
            }
        )) 
    }

But it gave the following error

This is the backend code written using express without the headers

app.get('/user',async(req,res)=>{
     const user=await getuser();
     res.send(user);
 })

After adding a header to the method problem was solved

app.get('/user',async(req,res)=>{
    res.header("Access-Control-Allow-Origin", "*");
    const user=await getuser();
    res.send(user);
})

With REGEXP_SUBSTR is as simple as:

SELECT REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 1) col_one,
       REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 2) col_two
FROM YOUR_TABLE t;

A node is defined as:

the smallest unit of a valid, complete structure in a document.

or as:

An object in the tree view that serves as a container to hold related objects.

Now their are many different kinds of nodes as an elements node, an attribute node etc.

Use maven and the plugin jaxws-maven-plugin. this will generate a web service client. Make sure you are setting the xadditionalHeaders to true. This will generate methods with header inputs.

I had the same problem a couple days ago. My development environment is Win8 and the website was working just fine, but when i uploaded the files to production server (Linux) was displaying a blank page.

Turns out that models and controllers's filenames should start with a uppercase letter.

The file must be called ‘Blog.php’, with a capital ‘B’.

Class names must start with an uppercase letter.

In windows environment this wont matter since windows does not differentiate uppercase and lowercase, but in linux environment, the files wont be displayed.

Hope I've helped.

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

setting the content-type to undefined would make javascript pass the header data As it is , and over writing the default angular $httpProvider header configurations. Angular $http Documentation

$http({url:url,method:"POST", headers:{'Content-Type':undefined}).then(success,failure);

key = "".join( chr( val ) for val in myList )

I am assuming what you are trying to achieve is to insert a line after the first few lines of of a textfile.

head -n10 file.txt >> newfile.txt
echo "your line >> newfile.txt
tail -n +10 file.txt >> newfile.txt

If you don't want to rest of the lines from the file, just skip the tail part.

Append IDs at the class declaration

.aclass, #hashone, #hashtwo{ ...codes... }
document.getElementById( "hashone" ).style.visibility = "hidden";

One way to do this is to insert a dummy column with the sums in order to sort:

In [10]: sum_B_over_A = df.groupby('A').sum().B

In [11]: sum_B_over_A
Out[11]: 
A
bar    0.253652
baz   -2.829711
foo    0.551376
Name: B

in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)

In [13]: df
Out[13]: 
     A         B      C  sum_B_over_A
0  foo  1.624345  False      0.551376
1  bar -0.611756   True      0.253652
2  baz -0.528172  False     -2.829711
3  foo -1.072969   True      0.551376
4  bar  0.865408  False      0.253652
5  baz -2.301539   True     -2.829711

In [14]: df.sort(['sum_B_over_A', 'A', 'B'])
Out[14]: 
     A         B      C   sum_B_over_A
5  baz -2.301539   True      -2.829711
2  baz -0.528172  False      -2.829711
1  bar -0.611756   True       0.253652
4  bar  0.865408  False       0.253652
3  foo -1.072969   True       0.551376
0  foo  1.624345  False       0.551376

and maybe you would drop the dummy row:

In [15]: df.sort(['sum_B_over_A', 'A', 'B']).drop('sum_B_over_A', axis=1)
Out[15]: 
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

This terminal command:

open /Applications/Python\ 3.7/Install\ Certificates.command

Found here: https://stackoverflow.com/a/57614113/6207266

Resolved it for me. With my config

pip install --upgrade certifi

had no impact.

Java documentation is helpful to know the root cause of a particular IOException.

Just have a look at the direct known sub-interfaces of IOException from the documentation page:

ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException

Most of these exceptions are self-explanatory.

A few IOExceptions with root causes:

EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.

SocketException: Thrown to indicate that there is an error creating or accessing a Socket.

RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.

UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).

MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.

When you normalize a matrix using NORM_L1, you are dividing every pixel value by the sum of absolute values of all the pixels in the image. As a result, all pixel values become much less than 1 and you get a black image. Try NORM_MINMAX instead of NORM_L1.

When creating the TABLE under B2BOWNER, be sure to prefix the PL/SQL function with the Schema name; i.e. B2BOWNER.F_SSC_Page_Map_Insert.

I did not realize this until the DBAs pointed it out. I could have created the table under my root USER/SCHEMA and the PL/SQL function would have worked fine.

This worked for me:

.dropdown, .dropdown-menu {
  z-index:2;
}
.navbar {
  position: static;
  z-index: 1;
}

For closing (not quit) the running application in Simulator the keyboard shortcut is "shift+command+h".

The easiest way is:

echo. > Filename.txt

I just configured min as the following :

spring.h2.console.enabled=true
spring.h2.console.path=/h2-console


# changing the name of my data base for testing
spring.datasource.url= jdbc:h2:mem:mockedDB
spring.datasource.username=sa
spring.datasource.password=sa



# in testing i don`t need to know the port

#Feature that determines what happens when no accessors are found for a type
#(and there are no annotations to indicate it is meant to be serialized).
spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false`enter code here`

For Converting an Image object to byte[] you can do as follows:

public static byte[] converterDemo(Image x)
{
    ImageConverter _imageConverter = new ImageConverter();
    byte[] xByte = (byte[])_imageConverter.ConvertTo(x, typeof(byte[]));
    return xByte;
}

Recommendation:

when you have more than one condition with and and or is better separate with () to avoid verification problems

<c:if test="${(not validID) and (addressIso == 'US' or addressIso == 'BR')}">

Interestingly, both C & C++ (and I think C#, but I'm not sure) specifically allow the trailing comma -- for exactly the reason given: It make programmaticly generating lists much easier. Not sure why JavaScript didn't follow their lead.

Here's something that might be interesting for developers hacking (minified or obfuscated) JavaScript more frequently.

You can build your own CLI JavaScript beautifier in under 5 mins and have it handy on the command-line. You'll need Mozilla Rhino, JavaScript file of some of the JS beautifiers available online, small hack and a script file to wrap it all up.

I wrote an article explaining the procedure: Command-line JavaScript beautifier implemented in JavaScript.

Not every DB schema can be converted. MySQL is more complex and feature-rich than SQLite. However, if your schema is simple enough, you could dump it into an SQL file and try to import it / load it into an SQLite DB.

I had the same issue. I added following attributes to <xs:schema..> elementFormDefault="qualified" attributeFormDefault="unqualified"

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns="http://www.example.com/schemas/ArrayOfMarketWithStations"
    targetNamespace="http://www.example.com/schemas/ArrayOfMarketWithStations" 
    elementFormDefault="qualified" attributeFormDefault="unqualified" >

and re-generated java classes by running xjc, which corrected package-info.java.

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.com/schemas/ArrayOfMarketWithStations", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)

This fixed the issue for me.

Type on sqlplus command prompt

SQL> select * from global_name;

then u will be see result on command prompt

SQL ORCL.REGRESS.RDBMS.DEV.US.ORACLE.COM

Here first one "ORCL" is database name,may be your system "XE" and other what was given on oracle downloading time.

You can do :

1) javac -cp /path/to/jar/file Myprogram.java

2) java -cp .:/path/to/jar/file Myprogram

So, lets suppose your current working directory in terminal is src/Report/

javac -cp src/external/myfile.jar Reporter.java

java -cp .:src/external/myfile.jar Reporter

Take a look here to setup Classpath

The best one by far is

bool(re.search('ba[rzd]', 'foobarrrr'))

Returns True

It is an "INEQUALITY" operator. Get a list of comparison operators in VBA

Jasmine doesn't have that functionality, but you might be able to hack something together using Object.defineProperty.

You could refactor your code to use a getter function, then spy on the getter.

spyOn(myObj, 'getValueA').andReturn(1);
expect(myObj.getValueA()).toBe(1);

Kotlin version with update for deprication of RequestBody.create :

Retrofit interface

@Multipart
@POST("uploadPhoto")
fun uploadFile(@Part file: MultipartBody.Part): Call<FileResponse>

and to Upload

fun uploadFile(fileUrl: String){
    val file = File(fileUrl)
    val fileUploadService = RetrofitClientInstance.retrofitInstance.create(FileUploadService::class.java)
    val requestBody = file.asRequestBody(file.extension.toMediaTypeOrNull())
    val filePart = MultipartBody.Part.createFormData(
        "blob",file.name,requestBody
    )
    val call = fileUploadService.uploadFile(filePart)

    call.enqueue(object: Callback<FileResponse>{
        override fun onFailure(call: Call<FileResponse>, t: Throwable) {
            Log.d(TAG,"Fckd")
        }

        override fun onResponse(call: Call<FileResponse>, response: Response<FileResponse>) {
            Log.d(TAG,"success"+response.toString()+" "+response.body().toString()+"  "+response.body()?.status)
        }

    })
}

If you want insert all data from one table to another table there is a very simply sql

INSERT INTO destinationTable  (SELECT * FROM sourceDbName.SourceTableName);

For a web service hosted in ASP.NET, the configuration property is executionTimeout:

<configuration> <system.web>

<httpRuntime executionTimeout="360" />

</system.web>

</configuration>

Set this and the thread abort exception will go away :)

Installing a newer release of IDEA Community (2018.3 instead of 2017.x) was solved my issue with same error but java version:11. Reimport hadn't worked for me. But it worth a try.

Further hint: If you don't need those information you can change the Table Type to "Blackhole" (instead of InnoDB). This means, nothing will be stored in the future and the insert statements are still working fine.

You can also disable the logs by setting all events to disabled:

A sort of block comment uses an if statement:

if(FALSE) {
  all your code
}

It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).

User interactive approach:

git clean -i -fd

Remove .classpath [y/N]? N
Remove .gitignore [y/N]? N
Remove .project [y/N]? N
Remove .settings/ [y/N]? N
Remove src/com/amazon/arsdumpgenerator/inspector/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/s3/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/s3/ [y/N]? y

-i for interactive
-f for force
-d for directory
-x for ignored files(add if required)

Note: Add -n or --dry-run to just check what it will do.

Well, In my case the solution was quite simple and straight.

I had to change just the value of log On As value.

Steps to Resolve-

1. Open Sql Server Configuration manager
2. Right click on SQL Server (MSSQLSERVER)
3. Go to Properties

4. change log On As value to LocalSystem

Hoping this will help you too :)

Try this if other answers did not work for you.

For me This happened for API 27 Emulator.

API 26 Emulator worked just fine. So I started API 26 Emulator first and then closed it.

Then I started API 27 Emulator and It worked with No errors at all.

The correct way of use forms now in Angular2 is:

<form  (ngSubmit)="onSubmit()">

        <label>Username:</label>
        <input type="text" class="form-control"   [(ngModel)]="user.username" name="username" #username="ngModel" required />

        <label>Contraseña:</label>
        <input type="password" class="form-control"  [(ngModel)]="user.password" name="password" #password="ngModel" required />


    <input type="submit" value="Entrar" class="btn btn-primary"/>

</form>

The old way doesn't works anymore

Anyone can use underscore _ (its Okay)

No one should use hypen - (its Bad practice)

No one should use capital letters inside package names (Bad practice)

NOTE: Here "Bad Practice" is meant for technically you are allowed to use that, but conventionally its not in good manners to write.

You can use ffprobe to get frame number with the following commands

1. first method

ffprobe.exe -i video_name -print_format json -loglevel fatal -show_streams -count_frames -select_streams v

which tell to print data in json format

select_streams v will tell ffprobe to just give us video stream data and if you remove it, it will give you audio information as well

and the output will be like

    "streams": [
        {
            "index": 0,
            "codec_name": "mpeg4",

            }
        }
    ]
}

2. you can use

ffprobe -v error -show_format -show_streams video_name

which will give you stream data, if you want selected information like frame rate, use the following command

ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 video_name

which give a number base on your video information, the problem is when you use this method, its possible you get a N/A as output.

You may try this

pip install --upgrade tensorflow

this works for me. You still get the errors but they're easy enough to suppress. it also works from within subfolders!

git status >/dev/null 2>&1 && echo Hello World!

You can put this in an if then statement if you need to conditionally do more.

Polling the last modified file property is a simple yet effective solution though. Just define a class extending my FileChangedWatcher and implement the onModified() method:

import java.io.File;

public abstract class FileChangedWatcher
{
    private File file;

    public FileChangedWatcher(String filePath)
    {
        file = new File(filePath);
    }

    public void watch() throws InterruptedException
    {
        long currentModifiedDate = file.lastModified();

        while (true)
        {
            long newModifiedDate = file.lastModified();

            if (newModifiedDate != currentModifiedDate)
            {
                currentModifiedDate = newModifiedDate;
                onModified();
            }

            Thread.sleep(100);
        }
    }

    public String getFilePath()
    {
        return file.getAbsolutePath();
    }

    protected abstract void onModified();
}

You can call sortable on a <tbody> instead of on the individual rows.

You can take the SelectedItem and cast it back to your class and access its properties.

 MessageBox.Show(((ComboboxItem)ComboBox_Countries_In_Silvers.SelectedItem).Value);

Edit You can try using DataTextField and DataValueField, I used it with DataSource.

ComboBox_Servers.DataTextField = "Text";
ComboBox_Servers.DataValueField = "Value";

A BigDecimal is an exact way of representing numbers. A Double has a certain precision. Working with doubles of various magnitudes (say d1=1000.0 and d2=0.001) could result in the 0.001 being dropped alltogether when summing as the difference in magnitude is so large. With BigDecimal this would not happen.

The disadvantage of BigDecimal is that it's slower, and it's a bit more difficult to program algorithms that way (due to + - * and / not being overloaded).

If you are dealing with money, or precision is a must, use BigDecimal. Otherwise Doubles tend to be good enough.

I do recommend reading the javadoc of BigDecimal as they do explain things better than I do here :)

Note that You can configure Apache so that all files With .inc extension are forbidden to be retrieved by visiting URL directly.

Oracle 11g provides a PIVOT operation that does what you want.

Oracle 11g solution

select * from
(select id, k, v from _kv) 
pivot(max(v) for k in ('name', 'age', 'gender', 'status')

(Note: I do not have a copy of 11g to test this on so I have not verified its functionality)

I obtained this solution from: http://orafaq.com/wiki/PIVOT

EDIT -- pivot xml option (also Oracle 11g)
Apparently there is also a pivot xml option for when you do not know all the possible column headings that you may need. (see the XML TYPE section near the bottom of the page located at http://www.oracle.com/technetwork/articles/sql/11g-pivot-097235.html)

select * from
(select id, k, v from _kv) 
pivot xml (max(v)
for k in (any) )

(Note: As before I do not have a copy of 11g to test this on so I have not verified its functionality)

Edit2: Changed v in the pivot and pivot xml statements to max(v) since it is supposed to be aggregated as mentioned in one of the comments. I also added the in clause which is not optional for pivot. Of course, having to specify the values in the in clause defeats the goal of having a completely dynamic pivot/crosstab query as was the desire of this question's poster.

The formatting can be done like this (I assumed you meant HH:MM instead of HH:SS, but it's easy to change):

Time.now.strftime("%d/%m/%Y %H:%M")
#=> "14/09/2011 14:09"

Updated for the shifting:

d = DateTime.now
d.strftime("%d/%m/%Y %H:%M")
#=> "11/06/2017 18:11"
d.next_month.strftime("%d/%m/%Y %H:%M")
#=> "11/07/2017 18:11"

You need to require 'date' for this btw.

In C & C++ single quotes is known as a character ('a') whereas double quotes is know as a string ("Hello"). The difference is that a character can store anything but only one alphabet/number etc. A string can store anything. But also remember that there is a difference between '1' and 1. If you type cout<<'1'<<endl<<1; The output would be the same, but not in this case:

cout<<int('1')<<endl<<int(1);

This time the first line would be 48. As when you convert a character to an int it converts to its ascii and the ascii for '1' is 48. Same, if you do:

string s="Hi";
s+=48; //This will add "1" to the string
s+="1"; This will also add "1" to the string
