Get all distinct id, name and address columns and count the resulting rows.

SELECT COUNT(*) FROM mytable GROUP BY id, name, address

I wanted to do the same thing from a script using a variable and achieved it by putting quotes around the $variable to separate the variable name from the p:

sed -n "$first","$count"p imagelist.txt >"$imageblock"

I wanted to split a list into separate folders and found the initial question and answer a useful step. (split command not an option on the old os I have to port code to).

You can use numpy.loadtext(filename). For example if this is your database .csv:

ID | Name | Address | City | State | Zip | Phone | OPEID | IPEDS |
10 | Adam | 130 W.. | Mo.. | AL... | 3.. | 334.. | 01023 | 10063 |
10 | Carl | 130 W.. | Mo.. | AL... | 3.. | 334.. | 01023 | 10063 |
10 | Adolf | 130 W.. | Mo.. | AL... | 3.. | 334.. | 01023 | 10063 |
10 | Den | 130 W.. | Mo.. | AL... | 3.. | 334.. | 01023 | 10063 |

And you want the Name column:

import numpy as np 
b=np.loadtxt(r'filepath\name.csv',dtype=str,delimiter='|',skiprows=1,usecols=(1,))

>>> b
array([' Adam ', ' Carl ', ' Adolf ', ' Den '], 
      dtype='|S7')

More easily you can use genfromtext:

b = np.genfromtxt(r'filepath\name.csv', delimiter='|', names=True,dtype=None)
>>> b['Name']
array([' Adam ', ' Carl ', ' Adolf ', ' Den '], 
      dtype='|S7')

Update 2016

As mentioned by ralfstx's answer, Eclipse 4.6 M4 Neon (or more) has a word-wrap feature!
(Nov 2015, for release mid 2016). In any editor view, type:

Alt+Shift+Y

(Sadik confirms in the comments it works with Eclipse 2019-09)

By default, text editors are opened with word wrap disabled.
This can be changed with the Enable word wrap when opening an editor option on the General > Editors > Text Editors preference page.

Manually toggle word wrap by clicking in the editor window and pressing (Shift+Alt+Y).
On Mac OS X, press (Cmd-Opt-Y). [Updated May 2017]

The famous bug 35779 is finally closed by r/#/c/61972/ last November.

There are however a few new bugs:

• 481873 "No line ruler number repaint on text editing with disabled "quick diff""
• 484142: "Word Wrap makes some actions very slow"
• 488162: "[word wrap] Hide WW preference to avoid unexpected performance impact"

As long as we are unable to provide acceptable editor performance for big files after toggling editor word wrap state on, we should make sure users can't set WW preference 1 always on by default and wonder why the editors are slow during resizing/zooming.

(2020) MarcGuay adds in the comments:

If you want the wrapping to be persistent/automatic, the cdhq plugin seems to still work with the 2019-03 version of Eclipse.
After installing you can turn it on via Window->Preferences->Word Wrap.

Update 2014

The de.cdhq.eclipse.wordwrap Word-Wrap Eclipse plug-in just got updated, and does provide good wrapping, as illustrated in the project page:

Original answer May 2010

Try the Eclipse Word-Wrap Plug-In here.

Just for the record, while Eclipse Colorer might bring wrapping for xml files, Eclipse has not in general a soft wrapping feature for Text editor.

Soft and hard. Soft will just warp the text at the right window border without adding new line numbers (so there are gaps in the list of numbers when you enable them).

This is one of the most upvoted bugs in Eclipse history: bug 35779 (9 years and counting, 200+ votes)

Update February 2013:

That bug references an old Word wrap plugin, but Oak mentions in his answer (upvoted) a new plugin for recent (Juno+) versions of Eclipse (so 3.8.x, 4.x, may have been seen working with 3.7)
That plugin is from Florian Weßling, who just updated it (March 2013)

Right click in an opened file and select "Toggle Word Wrap" (shortcut ctrl+alt+e)

Just start emulator by command line as follow:

emulator -avd <your avd name> -partition-size 1024 -wipe-data

In simple terms you need to build your payload into a key array

payload = {'key1': 'value1', 'key2': 'value2'}

Then send the payload directly to the action

this.$store.dispatch('yourAction', payload)

No change in your action

yourAction: ({commit}, payload) => {
  commit('YOUR_MUTATION',  payload )
},

In your mutation call the values with the key

'YOUR_MUTATION' (state,  payload ){
  state.state1 = payload.key1
  state.state2 =  payload.key2
},

This answer only applies to ancient versions of Visual Studio - see the more recent answers for modern versions.

You can set Visual Studio's global include path here:

Tools / Options / Projects and Solutions / VC++ Directories / Include files

from tkinter import *
from PIL import ImageTk, Image

window = Tk()
window.geometry("1000x300")

path = "1.jpg"

image = PhotoImage(Image.open(path))

panel = Label(window, image = image)

panel.pack()

window.mainloop()

Use the right attribute of the current instance (e.g. @work.project_id):

<%= f.select :project_id, options_for_select(..., @work.project_id) %>

Yes the tab character is one character. You can match it in java with "\t".

You can press CTLR+F8 to activate or deactivate breackpoints.

This is the short solution.

Yes, the first means "match all strings that start with a letter", the second means "match all strings that contain a non-letter". The caret ("^") is used in two different ways, one to signal the start of the text, one to negate a character match inside square brackets.

All the answers are accepted, you can do this by many ways. One of the trick to do this is this.

 const str = "Test abc test test abc test test test abc test test abc";_x000D_
    _x000D_
    const compare = "abc";_x000D_
    arrayStr = str.split(" ");_x000D_
    arrayStr.forEach((element, index) => {_x000D_
      if (element == compare) {_x000D_
        arrayStr.splice(index, 1);_x000D_
      }_x000D_
    });_x000D_
    const newString = arrayStr.join(" ");_x000D_
    console.log(newString);

There is no native indexof method in java arrays.You will need to write your own method for this.

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

See Getting BLOB data from XHR request which points out that BlobBuilder doesn't work in Chrome so you need to use:

xhr.responseType = 'arraybuffer';

It is an extremely overused way to check for the success/failure of a command. Typically, the code snippet you give would be refactored as:

if grep -e ERROR ${LOG_DIR_PATH}/${LOG_NAME} > /dev/null; then
   ...
fi

(Although you can use 'grep -q' in some instances instead of redirecting to /dev/null, doing so is not portable. Many implementations of grep do not support the -q option, so your script may fail if you use it.)

I'm not really sure if I got your question right. Maybe something like

public class CommentsController : Controller
{
    [HttpPost]
    public ActionResult WriteComment(CommentModel comment)
    {
        // Do the basic model validation and other stuff
        try
        {
            if (ModelState.IsValid )
            {
                 // Insert the model to database like:
                 db.Comments.Add(comment);
                 db.SaveChanges();

                 // Pass the comment's article id to the read action
                 return RedirectToAction("Read", "Articles", new {id = comment.ArticleID});
            }
        }
        catch ( Exception e )
        {
             throw e;
        }
        // Something went wrong
        return View(comment);

    }
}


public class ArticlesController : Controller
{
    // id is the id of the article
    public ActionResult Read(int id)
    {
        // Get the article from database by id
        var model = db.Articles.Find(id);
        // Return the view
        return View(model);
    }
}

easy way to do it

Begin = new DateTime(DateTime.Now.Year, DateTime.Now.Month,1).ToShortDateString();
End = new DataFim.Text = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month)).ToShortDateString();

You should use something similar to this for adding TextView to LinearLayout dynamically:

LinearLayout linearLayout = getActivity().findViewById(R.id.infoLayout);

TextView valueTV = new TextView(context);
valueTV.setText("hallo hallo");
valueTV.setId(Integer.parseInt("5"));
valueTV.setLayoutParams(new LinearLayout.LayoutParams(
       LinearLayout.LayoutParams.FILL_PARENT,
       LinearLayout.LayoutParams.WRAP_CONTENT));

linearLayout.addView(valueTV);

getActivity() is used for inside Fragments, you can use context or anything similar per each instance you are inside.

$ PATH=$PATH:/Library/PostgreSQL/9.1/bin sudo gem install pg

replace the 9.1 for the version installed on your system.

What is gone is gone. The only protection I know of is regular backup.

The focus only works if the window is focused.

Use ((JavascriptExecutor)webDriver).executeScript("window.focus();"); to be sure.

A good plugin that I have used before is DataTables.

I faced this problem on the formative project of my young career.

The approach I took was to save the values and the names of the enumeration externally, and the end goal was to be able to write code that looked as close to a language enum as possible.

I wanted my solution to look like this:

enum HatType
{
    BASEBALL,
    BRIMLESS,
    INDIANA_JONES
}

HatType mine = HatType.BASEBALL;

// prints "BASEBALL"
System.out.println(mine.toString());

// prints true
System.out.println(mine.equals(HatType.BASEBALL));

And I ended up with something like this:

// in a file somewhere:
// 1 --> BASEBALL
// 2 --> BRIMLESS
// 3 --> INDIANA_JONES

HatDynamicEnum hats = HatEnumRepository.retrieve();

HatEnumValue mine = hats.valueOf("BASEBALL");

// prints "BASEBALL"
System.out.println(mine.toString());

// prints true
System.out.println(mine.equals(hats.valueOf("BASEBALL"));

Since my requirements were that it had to be possible to add members to the enum at run-time, I also implemented that functionality:

hats.addEnum("BATTING_PRACTICE");

HatEnumRepository.storeEnum(hats);

hats = HatEnumRepository.retrieve();

HatEnumValue justArrived = hats.valueOf("BATTING_PRACTICE");
// file now reads:
// 1 --> BASEBALL
// 2 --> BRIMLESS
// 3 --> INDIANA_JONES
// 4 --> BATTING_PRACTICE

I dubbed it the Dynamic Enumeration "pattern", and you read about the original design and its revised edition.

The difference between the two is that the revised edition was designed after I really started to grok OO and DDD. The first one I designed when I was still writing nominally procedural DDD, under time pressure no less.

I solved this rather easily (without adding a method) so i'll share:

use Doctrine\Common\Collections\Criteria;

$repository->matching( Criteria::create()->where( Criteria::expr()->neq('id', 1) ) );

By the way, i'm using the Doctrine ORM module from within Zend Framework 2 and i'm not sure whether this would be compatible in any other case.

In my case, i was using a form element configuration like this: to show all roles except "guest" in a radio button array.

$this->add(array(
    'type' => 'DoctrineModule\Form\Element\ObjectRadio',
        'name' => 'roles',
        'options' => array(
            'label' => _('Roles'),
            'object_manager' => $this->getEntityManager(),
            'target_class'   => 'Application\Entity\Role',
            'property' => 'roleId',
            'find_method'    => array(
                'name'   => 'matching',
                'params' => array(
                    'criteria' => Criteria::create()->where(
                        Criteria::expr()->neq('roleId', 'guest')
                ),
            ),
        ),
    ),
));

Assuming you want to get the value if the key does exist, use Dictionary<TKey, TValue>.TryGetValue:

int value;
if (dictionary.TryGetValue(key, out value))
{
    // Key was in dictionary; "value" contains corresponding value
} 
else 
{
    // Key wasn't in dictionary; "value" is now 0
}

(Using ContainsKey and then the the indexer makes it look the key up twice, which is pretty pointless.)

Note that even if you were using reference types, checking for null wouldn't work - the indexer for Dictionary<,> will throw an exception if you request a missing key, rather than returning null. (This is a big difference between Dictionary<,> and Hashtable.)

You can use:

public YourClass[] AllProducts()
{
    try
    {
        using (UserDataDataContext db = new UserDataDataContext())
        {
            return db.mrobProducts.Where(x => x.Status == 1)
                           .OrderBy(x => x.ID)
                           .Select(x => new YourClass { ID = x.ID, Name = x.Name, Price = x.Price})
                           .ToArray();
        }
    }
    catch
    {
        return null;
    }
}

And here is YourClass implementation:

public class YourClass
{
  public string Name {get; set;}
  public int ID {get; set;}
  public int Price {get; set;}
}

And your AllProducts method's return type must be YourClass[].

If you are using MYSQL-WORKBENCH, then you can select blob column normally and right click on column and click open value in editor. refer screenshot:

Spring MVC will give you the HttpRequest if you just add it to your controller method signature:

For instance:

/**
 * Generate a PDF report...
 */
@RequestMapping(value = "/report/{objectId}", method = RequestMethod.GET)
public @ResponseBody void generateReport(
        @PathVariable("objectId") Long objectId, 
        HttpServletRequest request, 
        HttpServletResponse response) {

    // ...
    // Here you can use the request and response objects like:
    // response.setContentType("application/pdf");
    // response.getOutputStream().write(...);

}

As you see, simply adding the HttpServletRequest and HttpServletResponse objects to the signature makes Spring MVC to pass those objects to your controller method. You'll want the HttpSession object too.

EDIT: It seems that HttpServletRequest/Response are not working for some people under Spring 3. Try using Spring WebRequest/WebResponse objects as Eduardo Zola pointed out.

I strongly recommend you to have a look at the list of supported arguments that Spring MVC is able to auto-magically inject to your handler methods.

if you process the parameters immediately and then move to the next page, you can put a question mark on the end of the new location.

for example, if you would have done $location.path('/nextPage');

you can do this instead: $location.path('/nextPage?');

My first suggestion would be use your calendar table, if you don't have one, then create one. They are very useful. Your query is then as simple as:

DECLARE @MinDate DATE = '20140101',
        @MaxDate DATE = '20140106';

SELECT  Date
FROM    dbo.Calendar
WHERE   Date >= @MinDate
AND     Date < @MaxDate;

If you don't want to, or can't create a calendar table you can still do this on the fly without a recursive CTE:

DECLARE @MinDate DATE = '20140101',
        @MaxDate DATE = '20140106';

SELECT  TOP (DATEDIFF(DAY, @MinDate, @MaxDate) + 1)
        Date = DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a.object_id) - 1, @MinDate)
FROM    sys.all_objects a
        CROSS JOIN sys.all_objects b;

For further reading on this see:

• Generate a set or sequence without loops – part 1
• Generate a set or sequence without loops – part 2
• Generate a set or sequence without loops – part 3

With regard to then using this sequence of dates in a cursor, I would really recommend you find another way. There is usually a set based alternative that will perform much better.

So with your data:

  date   | it_cd | qty 
24-04-14 |  i-1  | 10 
26-04-14 |  i-1  | 20

To get the quantity on 28-04-2014 (which I gather is your requirement), you don't actually need any of the above, you can simply use:

SELECT  TOP 1 date, it_cd, qty 
FROM    T
WHERE   it_cd = 'i-1'
AND     Date <= '20140428'
ORDER BY Date DESC;

If you don't want it for a particular item:

SELECT  date, it_cd, qty 
FROM    (   SELECT  date, 
                    it_cd, 
                    qty, 
                    RowNumber = ROW_NUMBER() OVER(PARTITION BY ic_id 
                                                    ORDER BY date DESC)
            FROM    T
            WHERE   Date  <= '20140428'
        ) T
WHERE   RowNumber = 1;

You can also use

./gradlew clean build (Mac and Linux) -With ./

gradlew clean build (Windows) -Without ./

it removes build folder, as well configure your modules and then build your project.

i use it before release any new app on playstore.

Here is code for checked and unchecked with a button:

var set=1;
var unset=0;
jQuery( function() {
    $( '.checkAll' ).live('click', function() {
        $( '.cb-element' ).each(function () {
            if(set==1){ $( '.cb-element' ).attr('checked', true) unset=0; }
            if(set==0){ $( '.cb-element' ).attr('checked', false); unset=1; }
        });
        set=unset;
    });
});

Update: Here is the same code block using the newer Jquery 1.6+ prop method, which replaces attr:

var set=1;
var unset=0;
jQuery( function() {
    $( '.checkAll' ).live('click', function() {
        $( '.cb-element' ).each(function () {
            if(set==1){ $( '.cb-element' ).prop('checked', true) unset=0; }
            if(set==0){ $( '.cb-element' ).prop('checked', false); unset=1; }
        });
        set=unset;
    });
});

While I agree that in general inline-block is better, there's one extra thing to take into account if you're using percentage widths to create a responsive grid (or if you want pixel-perfect widths):

If you're using inline-block for grids that total 100% or near to 100% width, you need to make sure your HTML markup contains no white space between columns.

With floats, this is not something you need to worry about - the columns float over any whitespace or other content between columns. This question's answers have some good tips on ways to remove HTML whitespace without making your code ugly.

If for any reason you can't control the HTML markup (e.g. a restrictive CMS), you can try the tricks described here, or you might need to compromise and use floats instead of inline-block. There are also ugly CSS tricks that should only be used in extreme circumstances, like font-size:0; on the column container then reapply font size within each column.

For example:

• Here's a 3-column grid of 33.3% width with float: left. It "just works" (but for the wrapper needing to be cleared).
• Here's the exact same grid, with inline-block. The whitespace between blocks creates a fixed-width space which pushes the total width beyond 100%, breaking the layout and causing the last column to drop down a line.
• Here' s the same grid, with inline-block and no whitespace between columns in the HTML. It "just works" again - but the HTML is uglier and your CMS might force some kind of prettification or indenting to its HTML output making this difficult to achieve in reality.

Using index:

>>> string = "Username: How are you today?"
>>> string[:string.index(":")]
'Username'

The index will give you the position of : in string, then you can slice it.

If you want to use regex:

>>> import re
>>> re.match("(.*?):",string).group()
'Username'                       

match matches from the start of the string.

you can also use itertools.takewhile

>>> import itertools
>>> "".join(itertools.takewhile(lambda x: x!=":", string))
'Username'

using from ListSelectionModel:

ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
  public void valueChanged(ListSelectionEvent e) {
    String selectedData = null;

    int[] selectedRow = table.getSelectedRows();
    int[] selectedColumns = table.getSelectedColumns();

    for (int i = 0; i < selectedRow.length; i++) {
      for (int j = 0; j < selectedColumns.length; j++) {
        selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
      }
    }
    System.out.println("Selected: " + selectedData);
  }

});

see here.

Another way to do this:

1. Put your prefix in one column say column A in excel
2. Put the values to which you want to add prefix in another column say column B in excel
3. In Column C, use this formula;

"C1=A1&B1"

4. Copy all the values in column C and paste it again in the same selection but as values only.

I also had this issue. I'm using IntelliJ IDEA. I was using src/main/java for configuration files and src/test/java for test files.
Because of this testNG couldn't find the class path. To prevent getting that error need to move all the files from src/main/java to src/test/java or vice versa.

The other thing to be careful about, is to use the clf (clear figure) command when you are starting a fresh plot. Otherwise you may be plotting on a pre-existing figure (not possible with the figure command by itself, but if you do figure(2) there may already be a figure #2), with more than one axis, or an axis that is placed kinda funny. Use clf to ensure that you're starting from scratch:

figure(N);
clf;
plot(something);
...

Put this on an event

$(function(){
    $('.package').click(function(){
       var content = $('.container').html();
       $(this).html(content);
    });
});

I found the answer, and in spite of what I reported, it was NOT browser specific. The bug was in my function code, and would have occurred in any browser. It boils down to this. I had two lines in my code that were FireFox/FireBug specific. They used console.log. In IE, they threw an error, so I commented them out (or so I thought). I did a crappy job commenting them out, and broke the bracketing in my function.

Original Code (with console.log in it):

if (sxti.length <= 50) console.log('sxti=' + sxti);
if (sxph.length <= 50) console.log('sxph=' + sxph);

Broken Code (misplaced brackets inside comments):

if (sxti.length <= 50) { //console.log('sxti=' + sxti); }
if (sxph.length <= 50) { //console.log('sxph=' + sxph); }

Fixed Code (fixed brackets outside comments):

if (sxti.length <= 50) { }//console.log('sxti=' + sxti);
if (sxph.length <= 50) { }//console.log('sxph=' + sxph);

So, it was my own sloppy coding. The function really wasn't defined, because a syntax error kept it from being closed.

Oh well, live and learn. ;)

That's about it. There is no magic built-in function...

My own humble (case sensitive) solution:

uint8_t strContains(char* string, char* toFind)
{
    uint8_t slen = strlen(string);
    uint8_t tFlen = strlen(toFind);
    uint8_t found = 0;

    if( slen >= tFlen )
    {
        for(uint8_t s=0, t=0; s<slen; s++)
        {
            do{

                if( string[s] == toFind[t] )
                {
                    if( ++found == tFlen ) return 1;
                    s++;
                    t++;
                }
                else { s -= found; found=0; t=0; }

              }while(found);
        }
        return 0;
    }
    else return -1;
}

Results

XMLHttpRequest is a standard object in the JavaScript Object model.

According to Wikipedia, XMLHttpRequest first appeared in Internet Explorer 5 as an ActiveX object, but has since been made into a standard and has been included for use in JavaScript in the Mozilla family since 1.0, Apple Safari 1.2, Opera 7.60-p1, and IE 7.0.

The open() method on the object takes the HTTP Method as an argument - and is specified as taking any valid HTTP method (see the item number 5 of the link) - including GET, POST, HEAD, PUT and DELETE, as specified by RFC 2616.

As a side note IE 7–8 only permit the following HTTP methods: "GET", "POST", "HEAD", "PUT", "DELETE", "MOVE", "PROPFIND", "PROPPATCH", "MKCOL", "COPY", "LOCK", "UNLOCK", and "OPTIONS".

A FragmentActivity is a subclass of Activity that was built for the Android Support Package.

The FragmentActivity class adds a couple new methods to ensure compatibility with older versions of Android, but other than that, there really isn't much of a difference between the two. Just make sure you change all calls to getLoaderManager() and getFragmentManager() to getSupportLoaderManager() and getSupportFragmentManager() respectively.

You can actually still use ".css" and apply css transitions to the div being affected. So continue using ".css" and add the below styles to your stylesheet for "#hfont1". Since ".css" allows for a lot more properties than ".animate", this is always my preferred method.

#hfont1 {
    -webkit-transition: width 0.4s;
    transition: width 0.4s;
}

I recommend using https://github.com/aleksaan/diskusage utility which I wrote. Very simple and helpful. And very fast.

Just type in a command shell

diskusage.exe -path 'd:/go; d:/Books'

and get list of folders arranged by size

  1.| DIR: d:/go      | SIZE: 325.72 Mb   | DEPTH: 1 
  2.| DIR: d:/Books   | SIZE:  14.01 Mb   | DEPTH: 1 

This example was executed at 272ms on HDD.

You can increase depth of subfolders to analyze, for example:

diskusage.exe -path 'd:/go; d:/Books' -depth 2

and get sizes not only for selected folders but also for its subfolders

  1.| DIR: d:/go            | SIZE: 325.72 Mb   | DEPTH: 1 
  2.| DIR: d:/go/pkg        | SIZE: 212.88 Mb   | DEPTH: 2 
  3.| DIR: d:/go/src        | SIZE:  62.57 Mb   | DEPTH: 2 
  4.| DIR: d:/go/bin        | SIZE:  30.44 Mb   | DEPTH: 2

If you want to restore all of the files at once

Remember to use the period because it tells git to grab all of the files.

This command will reset the head and unstage all of the changes:

$ git reset HEAD . 

Then run this to restore all of the files:

$ git checkout .

Then doing a git status, you'll get:

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.

If your activity is being rendered as a dialog, simply add a button to your activity's xml,

<Button
    android:id="@+id/close_button"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Dismiss" />

Then attach a click listener in your Activity's Java code. In the listener, simply call finish()

Button close_button = (Button) findViewById(R.id.close_button);
close_button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        finish();
    }
});

That should dismiss your dialog, returning you to the calling activity.

If I understand correctly then it would be easier if you gave your image a transparent background and set the background container's background-color property without having to use filters and so on.

http://www.ajaxblender.com/howto-convert-image-to-grayscale-using-javascript.html

Shows you how to use filters in IE. Maybe if you leverage something from that. Not very cross-browser compatible though. Another option might be to have two images and use them as background-images (rather than img tags), swap one out after another using the :hover pseudo selector.

You can achieve this by utilizing the jsPDF library and the toDataURL function.

In my case the excel was frozen when using the formula of

B2=INDEX($A$2:$A$20, MATCH(0, COUNTIF($B$1:B1, $A$2:$A$20), 0))

because there was many rows (10000). So I did in another way which I show below.

I have copied my original list to a second column and then with the function of Excel "remove duplicates" I could find the list of unique values.

Copied from Microsoft Office Website:

Select all the rows, including the column headers, in the list 

you want to filter.

Click the top left cell of the range, and then drag to the bottom right cell.

On the Data menu, point to Filter, and then click Advanced Filter.
In the Advanced Filter dialog box, click Filter the list, in place.
Select the Unique records only check box, and then click OK.

The filtered list is displayed and the duplicate rows are hidden.

On the Edit menu, click Office Clipboard.

The Clipboard task pane is displayed.

Make sure the filtered list is still selected, and then click Copy Copy button.

The filtered list is highlighted with bounding outlines and the selection appears as an > > item at the top of the Clipboard.

On the Data menu, point to Filter, and then click Show All.

The original list is re-displayed.

Press the DELETE key.

The original list is deleted.

In the Clipboard, click on the filtered list item.

The filtered list appears in the same location as the original list.

If you don't need the gap to be exactly 2 lines high, you can add an empty view like this:

    <View
        android:layout_width="fill_parent"
        android:layout_height="30dp">
    </View>

I had this problem also. The issue was because I was running an old version of PHP (5.6) and once I upgraded to PHP 7.4 the errors went away.

This was on Amazon Linux 2 for me and the command to upgrade was:

amazon-linux-extras install php7.4

Other flavors of *nix might have it in their repositories otherwise if you're on a flavor of Linux then Remi might have it for you here: https://rpms.remirepo.net/

The trick is to implement a stable sort. I've created a Widget class that can contain your test data:

public class Widget : IComparable
{
    int x;
    int y;
    public int X
    {
        get { return x; }
        set { x = value; }
    }

    public int Y
    {
        get { return y; }
        set { y = value; }
    }

    public Widget(int argx, int argy)
    {
        x = argx;
        y = argy;
    }

    public int CompareTo(object obj)
    {
        int result = 1;
        if (obj != null && obj is Widget)
        {
            Widget w = obj as Widget;
            result = this.X.CompareTo(w.X);
        }
        return result;
    }

    static public int Compare(Widget x, Widget y)
    {
        int result = 1;
        if (x != null && y != null)                
        {                
            result = x.CompareTo(y);
        }
        return result;
    }
}

I implemented IComparable, so it can be unstably sorted by List.Sort().

However, I also implemented the static method Compare, which can be passed as a delegate to a search method.

I borrowed this insertion sort method from C# 411:

 public static void InsertionSort<T>(IList<T> list, Comparison<T> comparison)
        {           
            int count = list.Count;
            for (int j = 1; j < count; j++)
            {
                T key = list[j];

                int i = j - 1;
                for (; i >= 0 && comparison(list[i], key) > 0; i--)
                {
                    list[i + 1] = list[i];
                }
                list[i + 1] = key;
            }
    }

You would put this in the sort helpers class that you mentioned in your question.

Now, to use it:

    static void Main(string[] args)
    {
        List<Widget> widgets = new List<Widget>();

        widgets.Add(new Widget(0, 1));
        widgets.Add(new Widget(1, 1));
        widgets.Add(new Widget(0, 2));
        widgets.Add(new Widget(1, 2));

        InsertionSort<Widget>(widgets, Widget.Compare);

        foreach (Widget w in widgets)
        {
            Console.WriteLine(w.X + ":" + w.Y);
        }
    }

And it outputs:

0:1
0:2
1:1
1:2
Press any key to continue . . .

This could probably be cleaned up with some anonymous delegates, but I'll leave that up to you.

EDIT: And NoBugz demonstrates the power of anonymous methods...so, consider mine more oldschool :P

Here are the docs about the "new" format syntax. An example would be:

"({:d} goals, ${:d})".format(self.goals, self.penalties)

If both goals and penalties are integers (i.e. their default format is ok), it could be shortened to:

"({} goals, ${})".format(self.goals, self.penalties)

And since the parameters are fields of self, there's also a way of doing it using a single argument twice (as @Burhan Khalid noted in the comments):

"({0.goals} goals, ${0.penalties})".format(self)

Explaining:

• {} means just the next positional argument, with default format;
• {0} means the argument with index 0, with default format;
• {:d} is the next positional argument, with decimal integer format;
• {0:d} is the argument with index 0, with decimal integer format.

There are many others things you can do when selecting an argument (using named arguments instead of positional ones, accessing fields, etc) and many format options as well (padding the number, using thousands separators, showing sign or not, etc). Some other examples:

"({goals} goals, ${penalties})".format(goals=2, penalties=4)
"({goals} goals, ${penalties})".format(**self.__dict__)

"first goal: {0.goal_list[0]}".format(self)
"second goal: {.goal_list[1]}".format(self)

"conversion rate: {:.2f}".format(self.goals / self.shots) # '0.20'
"conversion rate: {:.2%}".format(self.goals / self.shots) # '20.45%'
"conversion rate: {:.0%}".format(self.goals / self.shots) # '20%'

"self: {!s}".format(self) # 'Player: Bob'
"self: {!r}".format(self) # '<__main__.Player instance at 0x00BF7260>'

"games: {:>3}".format(player1.games)  # 'games: 123'
"games: {:>3}".format(player2.games)  # 'games:   4'
"games: {:0>3}".format(player2.games) # 'games: 004'

Note: As others pointed out, the new format does not supersede the former, both are available both in Python 3 and the newer versions of Python 2 as well. Some may say it's a matter of preference, but IMHO the newer is much more expressive than the older, and should be used whenever writing new code (unless it's targeting older environments, of course).

Alerts aren't the best for displaying objects. Try console.log? If you still see Object Object in the console, use JSON.parse like this > var obj = JSON.parse(yourObject); console.log(obj)

You could also look at underscore.js, which provides utility methods like debounce:

var lazyLayout = _.debounce(calculateLayout, 300);
$(window).resize(lazyLayout);

Is there a way to convert an Integer[] array to an int[] array?

This gross omission from the Java core libraries seems to come up on pretty much every project I ever work on. And as convenient as the Trove library might be, I am unable to parse the precise requirements to meet LPGL for an Android app that statically links an LGPL library (preamble says ok, body does not seem to say the same). And it's just plain inconvenient to go rip-and-stripping Apache sources to get these classes. There has to be a better way.

For a typical XAMPP install on windows you probably have the php_sockets.dll in your C:\xampp\php\ext directory. All you got to do is go to php.ini in the C:\xampp\php directory and change the ;extension=php_sockets.dll to extension=php_sockets.dll.

Intent intent = getIntent();
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
finish();
startActivity(intent);

This allows you to reload with theme changes and hides the animations.

Check your real my.ini file location and set --defaults-file="location" with this command

mysql --defaults-file="C:\MYSQL\my.ini" -u root -p

This solution is permanently for your cmd Screen.

Yet another answer: Use parameter expansion on empty parameters:

# calls curl 4 times 
curl -s -w "\n" -X GET "http:{,,,}//www.google.com"

You can get the pyspark path in python using pip (if you have installed pyspark using PIP) as below

There are no unsigned integers in Java. All integers are signed and in big endian.

On the C side the each byte has tne LSB at the start is on the left and the MSB at the end.

It sounds like you are using LSB as Least significant bit, are you? LSB usually stands for least significant byte. Endianness is not bit based but byte based.

To convert from unsigned byte to a Java integer:

int i = (int) b & 0xFF;

To convert from unsigned 32-bit little-endian in byte[] to Java long (from the top of my head, not tested):

long l = (long)b[0] & 0xFF;
l += ((long)b[1] & 0xFF) << 8;
l += ((long)b[2] & 0xFF) << 16;
l += ((long)b[3] & 0xFF) << 24;

Actually i am getting return value from a another sp into @temp and then it @temp =1 then i want to inc the count of @SelectoneCount by 1 and so on. Please let me know what is the correct syntax.

What's wrong with:

IF @Temp = 1 --Or @Temp = 2 also?
BEGIN
    SET @SelectoneCount = @SelectoneCount + 1
END

(Although this does reek of being procedural code - not usually the best way to use SQL)

Try to use JSONP in your Ajax call. It will bypass the Same Origin Policy.

http://learn.jquery.com/ajax/working-with-jsonp/

Try example

$.ajax({
    url: "https://api.dailymotion.com/video/x28j5hv?fields=title",

    dataType: "jsonp",
    success: function( response ) {
        console.log( response ); // server response
    }

});

$month = 10; // october

$firstday = date('01-' . $month . '-Y');
$lastday = date(date('t', strtotime($firstday)) .'-' . $month . '-Y');

So simple you can use case statement here.

CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN 
         CASE WHEN  ISSUE_DIVISION is null then "Null Value found" //give your option
         Else 1 End
ELSE 0 END As Issue_Division_Result

To get the value of a pointer, just de-reference the pointer.

int *ptr;
int value;
*ptr = 9;

value = *ptr;

value is now 9.

I suggest you read more about pointers, this is their base functionality.

This may Happen because Activity "A" may have Fragments and when you navigate to Activity "B" .

then Activity Life Cycle of activty "A" will be

OnResume->OnPause()->OnSavedInsanceState()

here in OnSavedInsanceState may cause crash because it couldnt save state with to much data. so to try to clear the saveInsatnce of the Activity "A" by adding following code.

 @Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
    super.onSaveInstanceState(oldInstanceState);
    if (oldInstanceState != null) {
        oldInstanceState.clear();
    }

}

If you are worried about encoding, you can always use a switch statement.

Just be careful with the format you keep those large numbers in. The maximum size for an integer in some systems is as low as 65,535 (32,767 signed). Other systems, you've got 2,147,483,647 (or 4,294,967,295 unsigned)

SELECT MIN(id) as id FROM students where id>(SELECT MIN(id) FROM students);

This design was not mentioned yet:

Multiple lineage columns

Though it has limitations, if you can bear them, it's very simple and very efficient. Features:

• Columns: one for each lineage level, refers to all the parents up to the root, levels below the current items' level are set to 0 (or NULL)
• There is a fixed limit to how deep the hierarchy can be
• Cheap ancestors, descendants, level
• Cheap insert, delete, move of the leaves
• Expensive insert, delete, move of the internal nodes

Here follows an example - taxonomic tree of birds so the hierarchy is Class/Order/Family/Genus/Species - species is the lowest level, 1 row = 1 taxon (which corresponds to species in the case of the leaf nodes):

CREATE TABLE `taxons` (
  `TaxonId` smallint(6) NOT NULL default '0',
  `ClassId` smallint(6) default NULL,
  `OrderId` smallint(6) default NULL,
  `FamilyId` smallint(6) default NULL,
  `GenusId` smallint(6) default NULL,
  `Name` varchar(150) NOT NULL default ''
);

and the example of the data:

+---------+---------+---------+----------+---------+-------------------------------+
| TaxonId | ClassId | OrderId | FamilyId | GenusId | Name                          |

This is great because this way you accomplish all the needed operations in a very easy way, as long as the internal categories don't change their level in the tree.

There is one thing that many people don't realize right away when dealing with loops and invariants. They get confused between the loop invariant, and the loop conditional ( the condition which controls termination of the loop ).

As people point out, the loop invariant must be true

1. before the loop starts
2. before each iteration of the loop
3. after the loop terminates

( although it can temporarily be false during the body of the loop ). On the other hand the loop conditional must be false after the loop terminates, otherwise the loop would never terminate.

Thus the loop invariant and the loop conditional must be different conditions.

A good example of a complex loop invariant is for binary search.

bsearch(type A[], type a) {
start = 1, end = length(A)

    while ( start <= end ) {
        mid = floor(start + end / 2)

        if ( A[mid] == a ) return mid
        if ( A[mid] > a ) end = mid - 1
        if ( A[mid] < a ) start = mid + 1

    }
    return -1

}

So the loop conditional seems pretty straight forward - when start > end the loop terminates. But why is the loop correct? What is the loop invariant which proves it's correctness?

The invariant is the logical statement:

if ( A[mid] == a ) then ( start <= mid <= end )

This statement is a logical tautology - it is always true in the context of the specific loop / algorithm we are trying to prove. And it provides useful information about the correctness of the loop after it terminates.

If we return because we found the element in the array then the statement is clearly true, since if A[mid] == a then a is in the array and mid must be between start and end. And if the loop terminates because start > end then there can be no number such that start <= mid and mid <= end and therefore we know that the statement A[mid] == a must be false. However, as a result the overall logical statement is still true in the null sense. ( In logic the statement if ( false ) then ( something ) is always true. )

Now what about what I said about the loop conditional necessarily being false when the loop terminates? It looks like when the element is found in the array then the loop conditional is true when the loop terminates!? It's actually not, because the implied loop conditional is really while ( A[mid] != a && start <= end ) but we shorten the actual test since the first part is implied. This conditional is clearly false after the loop regardless of how the loop terminates.

This annotation is commonly used to eliminate NullPointerExceptions. @Nullable says that this parameter might be null. A good example of such behaviour can be found in Google Guice. In this lightweight dependency injection framework you can tell that this dependency might be null. If you would try to pass null without an annotation the framework would refuse to do it's job.

What is more @Nullable might be used with @NotNull annotation. Here you can find some tips on how to use them properly. Code inspection in IntelliJ checks the annotations and helps to debug the code.

You can't do it the way you've written it because C++ class member functions have a hidden this parameter passed in. pthread_create() has no idea what value of this to use, so if you try to get around the compiler by casting the method to a function pointer of the appropriate type, you'll get a segmetnation fault. You have to use a static class method (which has no this parameter), or a plain ordinary function to bootstrap the class:

class C
{
public:
    void *hello(void)
    {
        std::cout << "Hello, world!" << std::endl;
        return 0;
    }

    static void *hello_helper(void *context)
    {
        return ((C *)context)->hello();
    }
};
...
C c;
pthread_t t;
pthread_create(&t, NULL, &C::hello_helper, &c);

Just found sys.executable - the full path to the current Python executable, which can be used to run the script (instead of relying on the shbang, which obviously doesn't work on Windows)

import sys

theproc = subprocess.Popen([sys.executable, "myscript.py"])
theproc.communicate()

ASCII - Software allocates only 8 bit byte in memory for a given character. It works well for English & adopted (loanwords like façade) characters as their corresponding decimal values falls below 128 in the decimal value. Example C program.

UTF-8 - Software allocates 1 to 4 variable 8 bit bytes for a given character. What does mean by variable here? Let us say you are sending the character 'A' through your HTML pages in the browser (HTML is UTF-8), the corresponding decimal value of A is 65, when you convert it into decimal it becomes 01000010. This requires only 1 bytes, 1 byte memory is allocated even for special adopted English characters like 'ç' in a word façade. However, when you want to store European characters, it requires 2 bytes, so you need UTF-8. However, when you go for Asian characters, you require minimum of 2 bytes and maximum of 4 bytes. Similarly, Emoji's require 3 to 4 bytes. UTF-8 will solve all your needs.

UTF-16 will allocate minimum 2 bytes and maximum of 4 bytes per character, it will not allocate 1 or 3 bytes. Each character is either represented in 16 bit or 32 bit.

Then why exists UTF-16? Originally, Unicode was 16 bit not 8 bit. Java adopted the original version of UTF-16.

In a nutshell, you don't need UTF-16 anywhere unless it has been already been adopted by the language or platform you are working on.

Java program invoked by web browsers uses UTF-16 but the web browser sends characters using UTF-8.

you can simply write:

for item,i in zip(your_list, range(len(your_list)):

    if type(item) == list:
        print(f"{item} at index {i} is a list")

I guess you are using Rails 4. If so, the needed parameters must be marked as required.

You might want to do it like this:

class UsersController < ApplicationController

  def create
    @user = User.new(user_params)
    # ...
  end

  private

  def user_params
    params.require(:user).permit(:username, :email, :password, :salt, :encrypted_password)
  end
end

I was facing the same issue running my node js code on Windows VM on mac machine. The following code did the trick.

Replace

process.platform == 'win32'

with

const os = require('os');

os.platform() == 'win32';

EOF means end of file. It's a sign that the end of a file is reached, and that there will be no data anymore.

Edit:

I stand corrected. In this case it's not an end of file. As mentioned, it is passed when CTRL+d (linux) or CTRL+z (windows) is passed.

You can use query string to pass value from one page to another..

1.pass the value using querystring

 Response.Redirect("Default3.aspx?value=" + txt.Text + "& number="+n);

2.Retrive the value in the page u want by using any of these methods..

Method1:

    string v = Request.QueryString["value"];
    string n=Request.QueryString["number"];

Method2:

      NameValueCollection v = Request.QueryString;
    if (v.HasKeys())
    {
        string k = v.GetKey(0);
        string n = v.Get(0);
        if (k == "value")
        {
            lbltext.Text = n.ToString();
        }
        if (k == "value1")
        {
            lbltext.Text = "error occured";
        }
    }

NOTE:Method 2 is the fastest method.

Use split and map function:

var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });

Notice +val - string is casted to a number.

Or shorter:

var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });

edit 2015.07.29

Today I'd advise against using + operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number call:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
  return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);

edit 2017.03.09

ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);

I like to do this with sed. In you case:

for x in DET01-*.dat; do
    echo $x | sed -r 's/DET01-ABC-(.+)\.dat/mv -v "\0" "DET01-XYZ-\1.dat"/'
done | sh -e

It is best to omit the "sh -e" part first to see what will be executed.

What about:

tail -n +347340107 filename | head -n 100

I didn't test it, but I think that would work.

Parse a filename from the fully qualified path name (e.g., c:\temp\my.bat) to any component (e.g., File.ext).

Single line of code:

For %%A in ("C:\Folder1\Folder2\File.ext") do (echo %%~fA)

You can change out "C:\Folder1\Folder2\File.ext" for any full path and change "%%~fA" for any of the other options you will find by running "for /?" at the command prompt.

Elaborated Code

set "filename=C:\Folder1\Folder2\File.ext"
For %%A in ("%filename%") do (
    echo full path: %%~fA
    echo drive: %%~dA
    echo path: %%~pA
    echo file name only: %%~nA
    echo extension only: %%~xA
    echo expanded path with short names: %%~sA
    echo attributes: %%~aA
    echo date and time: %%~tA
    echo size: %%~zA
    echo drive + path: %%~dpA
    echo name.ext: %%~nxA
    echo full path + short name: %%~fsA)

Will the conditions be ORed or ANDed together?

Starts with: abc
Ends with: xyz
Contains: 123
Doesn't contain: 456

The OR version is fairly simple; as you said, it's mostly a matter of inserting pipes between individual conditions. The regex simply stops looking for a match as soon as one of the alternatives matches.

/^abc|xyz$|123|^(?:(?!456).)*$/

That fourth alternative may look bizarre, but that's how you express "doesn't contain" in a regex. By the way, the order of the alternatives doesn't matter; this is effectively the same regex:

/xyz$|^(?:(?!456).)*$|123|^abc/

The AND version is more complicated. After each individual regex matches, the match position has to be reset to zero so the next regex has access to the whole input. That means all of the conditions have to be expressed as lookaheads (technically, one of them doesn't have to be a lookahead, I think it expresses the intent more clearly this way). A final .*$ consummates the match.

/^(?=^abc)(?=.*xyz$)(?=.*123)(?=^(?:(?!456).)*$).*$/

And then there's the possibility of combined AND and OR conditions--that's where the real fun starts. :D

Step 1

Create and switch to a new "dev" branch, where your local git files are in-synced with the remote but "dev" branch does not exist yet.

git branch dev # create
git checkout dev # switch
# No need to git add or git commit, the current
# branch's files will be cloned to the new branch by-default.
git push --set-upstream origin dev # push the "dev" branch to the remote.

Step 2

Make your changes to the "dev" branch (your current if you follow step 1), commit and push them to the remote "dev" branch.

git add .
git commit -S -m "my first commit to the dev branch" # remove the -S if you're not "secure", secure = when you already setup crypto private and public keys (i.e "verified" green sign in github)
git push -u origin dev # push the changes to the remote, -u origin dev is optional but good to use.

Step 3

Merge your "dev" branch into the "master".

git checkout dev # switch to "dev" branch if you're not already.
git merge master # optionally, this command is being used to resolve any conflicts if you pushed any changes to your "master" but "dev" doesn't have that commit.
git checkout master # switch to "master", which is the branch you want to be merged.
git merge --no-ff dev # merge the "dev" branch into the "master" one.

Slightly shorter version using methods chain:

var list = new List<string> {"a", "b", "a", "c", "a", "b"};
var q = list.GroupBy(x => x)
            .Select(g => new {Value = g.Key, Count = g.Count()})
            .OrderByDescending(x=>x.Count);

foreach (var x in q)
{
    Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
}

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

Manually:

int strlen(string s)
{
    int len = 0;

    while (s[len])
        len++;

    return len;
}

Based on @Joaquin Astelarra response, I have managed to write this little helper named load_controller_helper.php:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

if (!function_exists('load_controller'))
{
    function load_controller($controller, $method = 'index')
    {
        require_once(FCPATH . APPPATH . 'controllers/' . $controller . '.php');

        $controller = new $controller();

        return $controller->$method();
    }
}

You can use/call it like this:

$this->load->helper('load_controller');
load_controller('homepage', 'not_found');

Note: The second argument is not mandatory, as it will run the method named index, like CodeIgniter would.

Now you will be able to load a controller inside another controller without using HMVC.

Later Edit: Be aware that this method might have unexpected results. Always test it!

Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:

*** Phones:

• HTC Sensation
• HTC Sensation XL
• HTC Evo 3D
• HTC One S
• HTC One X
• Huawei Ascend P1
• Huawei Ascend X (U9000)
• Huawei Honor (U8860)
• LG Nitro HD (P930)
• LG Optimus 2x (P990)
• LG Optimus Black (P970)
• LG Optimus 3D (P920)
• Samsung Galaxy S II (i9100)
• Samsung Galaxy S III (i9300)
• Samsung Galaxy R (i9103)
• Samsung Google Nexus S (i9020)
• Samsung Galaxy Nexus (i9250)

Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.

I'd a similar problem in a legacy application, but de "--" was string parameter.

Ex.:

Dim cmd As New OracleCommand("INSERT INTO USER (name, address, photo) VALUES ('User1', '--', :photo)", oracleConnection)
Dim fs As IO.FileStream = New IO.FileStream("c:\img.jpg", IO.FileMode.Open)
Dim br As New IO.BinaryReader(fs)
cmd.Parameters.Add(New OracleParameter("photo", OracleDbType.Blob)).Value = br.ReadBytes(fs.Length)
cmd.ExecuteNonQuery() 'here throws ORA-01008

Changing address parameter value '--' to '00' or other thing, works.

As the main question:

Anybody know why this is not allowed?

is still not answered, I did a quick search and found a relatively new addition from a MySQL developer at MySQL Bugs:

[17 Mar 2017 15:11] Ståle Deraas

Posted by developer:

This is indeed a valid feature request, and at first glance it might seem trivial to add. But TEXT/BLOBS values are not stored directly in the record buffer used for reading/updating tables. So it is a bit more complex to assign default values for them.

This is no definite answer, but at least a starting point for the why question.

In the mean time, I'll just code around it and either make the column nullable or explicitly assign a (default '') value for each insert from the application code...

This is an old question, but I stumbled onto this when looking for the answer so I wanted to give the update to the answer for reference.

The methods save and update are deprecated.

save(to_save, manipulate=True, check_keys=True, **kwargs)¶ Save a document in this collection.

DEPRECATED - Use insert_one() or replace_one() instead.

Changed in version 3.0: Removed the safe parameter. Pass w=0 for unacknowledged write operations.

update(spec, document, upsert=False, manipulate=False, multi=False, check_keys=True, **kwargs) Update a document(s) in this collection.

DEPRECATED - Use replace_one(), update_one(), or update_many() instead.

Changed in version 3.0: Removed the safe parameter. Pass w=0 for unacknowledged write operations.

in the OPs particular case, it's better to use replace_one.

In my view the most realistic scenario is when tasks have a heavy operation to complete. Shivprasad's approach focuses more on object creation/memory allocation than on computing itself. I made a research calling the following method:

public static double SumRootN(int root)
{
    double result = 0;
    for (int i = 1; i < 10000000; i++)
        {
            result += Math.Exp(Math.Log(i) / root);
        }
        return result; 
}

Execution of this method takes about 0.5sec.

I called it 200 times using Parallel:

Parallel.For(0, 200, (int i) =>
{
    SumRootN(10);
});

Then I called it 200 times using the old-fashioned way:

List<Task> tasks = new List<Task>() ;
for (int i = 0; i < loopCounter; i++)
{
    Task t = new Task(() => SumRootN(10));
    t.Start();
    tasks.Add(t);
}

Task.WaitAll(tasks.ToArray()); 

First case completed in 26656ms, the second in 24478ms. I repeated it many times. Everytime the second approach is marginaly faster.

On Ubuntu 14.04 I had to use a combination of previous answers.

First, install pip3 apt-get install python-pip3

Then with pip3 install jupyter pip3 install jupyter

Then using ipython3 install the kernel ipython3 kernel install

You can use ServiceLocatorFactoryBean. First you need to create an interface for your class

public interface YourClassFactory {
    YourClass getClassByName(String name);
}

Then you have to create a config file for ServiceLocatorBean

@Configuration
@Component
public class ServiceLocatorFactoryBeanConfig {

    @Bean
    public ServiceLocatorFactoryBean serviceLocatorBean(){
        ServiceLocatorFactoryBean bean = new ServiceLocatorFactoryBean();
        bean.setServiceLocatorInterface(YourClassFactory.class);
        return bean;
    }
}

Now you can find your class by name like that

@Autowired
private YourClassfactory factory;

YourClass getYourClass(String name){
    return factory.getClassByName(name);
}

Checking if v contains the element x:

#include <algorithm>

if(std::find(v.begin(), v.end(), x) != v.end()) {
    /* v contains x */
} else {
    /* v does not contain x */
}

Checking if v contains elements (is non-empty):

if(!v.empty()){
    /* v is non-empty */
} else {
    /* v is empty */
}

What about the Activity.finish() method (quoting) :

Call this when your activity is done and should be closed.

The -L merely gives the path where to find the .a or .so file. What you're looking for is to add -lmine to the LIBS variable.

Make that -static -lmine to force it to pick the static library (in case both static and dynamic library exist).

Addition: Suppose the path to the file has been conveyed to the linker (or compiler driver) via -L you can also specifically tell it to link libfoo.a by giving -l:libfoo.a. Note that in this case the name includes the conventional lib-prefix. You can also give a full path this way. Sometimes this is the better method to "guide" the linker to the right location.

var url = window.open("", "_blank");
url.location = "url";

this worked for me.

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.

/**
 * HTTP request types
 */
public static final int POST_TYPE   = 1;
public static final int GET_TYPE    = 2;
public static final int PUT_TYPE    = 3;
public static final int DELETE_TYPE = 4;

/**
 * HTTP request header constants
 */
public static final String CONTENT_TYPE         = "Content-Type";
public static final String ACCEPT_ENCODING      = "Accept-Encoding";
public static final String CONTENT_ENCODING     = "Content-Encoding";
public static final String ENCODING_GZIP        = "gzip";
public static final String MIME_FORM_ENCODED    = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN      = "text/plain";

private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
    final Map<String, String> headers, final Map<String, String> params, final int requestType) 
            throws IOException {

    DefaultHttpClient client = HTTPClientFactory.newClient();

    client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);

    // add user and pass to client credentials if present
    if ((user != null) && (pass != null)) {
        client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
    }

This can help you

namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
imshow( "Display window", image );                   // Show our image inside it.

And why not to use this ?

SELECT model, date FROM doc ORDER BY date DESC LIMIT 1

Except struct you can also use array module

import array
values = array.array('l') # array of long integers
values.read(fin, 1) # read 1 integer
file_size  = values[0]

Follow as in picture for removing that lint error and adding automatic fix by addin g--fix in package.json

You would use it as the first line of a subclass constructor to call the constructor of its parent class.

For example:

public class TheSuper{
    public TheSuper(){
        eatCake();
    }
}

public class TheSub extends TheSuper{
    public TheSub(){
        super();
        eatMoreCake();
    }
}

Constructing an instance of TheSub would call both eatCake() and eatMoreCake()

java.io.File doesn't represent an open file, it represents a path in the filesystem. Therefore having close method on it doesn't make sense.

Actually, this class was misnamed by the library authors, it should be called something like Path.

git tag

should be enough. See git tag man page

You also have:

git tag -l <pattern>

List tags with names that match the given pattern (or all if no pattern is given).
Typing "git tag" without arguments, also lists all tags.

More recently ("How to sort git tags?", for Git 2.0+)

git tag --sort=<type>

Sort in a specific order.

Supported type is:

• "refname" (lexicographic order),
• "version:refname" or "v:refname" (tag names are treated as versions).

Prepend "-" to reverse sort order.

That lists both:

• annotated tags: full objects stored in the Git database. They’re checksummed; contain the tagger name, e-mail, and date; have a tagging message; and can be signed and verified with GNU Privacy Guard (GPG).
• lightweight tags: simple pointer to an existing commit

Note: the git ready article on tagging disapproves of lightweight tag.

Without arguments, git tag creates a “lightweight” tag that is basically a branch that never moves.
Lightweight tags are still useful though, perhaps for marking a known good (or bad) version, or a bunch of commits you may need to use in the future.
Nevertheless, you probably don’t want to push these kinds of tags.

Normally, you want to at least pass the -a option to create an unsigned tag, or sign the tag with your GPG key via the -s or -u options.

That being said, Charles Bailey points out that a 'git tag -m "..."' actually implies a proper (unsigned annotated) tag (option '-a'), and not a lightweight one. So you are good with your initial command.

This differs from:

git show-ref --tags -d

Which lists tags with their commits (see "Git Tag list, display commit sha1 hashes").
Note the -d in order to dereference the annotated tag object (which have their own commit SHA1) and display the actual tagged commit.

Similarly, git show --name-only <aTag> would list the tag and associated commit.

@SpringBootApplication
@EnableConfigurationProperties
@EntityScan(basePackages = {"com.project.ppaa.model"})  // scan JPA entities
public class Application {

  private static ConfigurableApplicationContext applicationContext;

  public static void main(String[] args) {
    Application.applicationContext = SpringApplication.run(Application.class, args);
  }
}

it should work automatically but if it does not, you can enter the base package

@EntityScan(basePackages = {"com.project.ppaa.model"})  // scan JPA entities manually

I got blur working with SVG blur filter:

CSS

-webkit-filter: url(#svg-blur);
        filter: url(#svg-blur);

SVG

<svg id="svg-filter">
    <filter id="svg-blur">
        <feGaussianBlur in="SourceGraphic" stdDeviation="4"></feGaussianBlur>
    </filter>
</svg>

Working example:

Please note - this will not work in IE versions

If you want to set null value using update query set column value to NULL (without quotes) update tablename set columnname = NULL

However, if you are directly editing field value inside mysql workbench then use (Esc + del) keystroke to insert null value into selected column

I'd probably recommend using something like rsync for this due to its include and exclude flags, e.g:-

rsync -rav -e ssh --include '*/' --include='*.class' --exclude='*' \
server:/usr/some/unknown/number/of/sub/folders/ \ 
/usr/project/backup/some/unknown/number/of/sub/folders/

Some other useful flags:

• -r for recursive
• -a for archive (mostly all files)
• -v for verbose output
• -e to specify ssh instead of the default (which should be ssh, actually)

A URL that was created from a JavaScript Blob can not be converted to a "normal" URL.

A blob: URL does not refer to data the exists on the server, it refers to data that your browser currently has in memory, for the current page. It will not be available on other pages, it will not be available in other browsers, and it will not be available from other computers.

Therefore it does not make sense, in general, to convert a Blob URL to a "normal" URL. If you wanted an ordinary URL, you would have to send the data from the browser to a server and have the server make it available like an ordinary file.

It is possible convert a blob: URL into a data: URL, at least in Chrome. You can use an AJAX request to "fetch" the data from the blob: URL (even though it's really just pulling it out of your browser's memory, not making an HTTP request).

Here's an example:

var blob = new Blob(["Hello, world!"], { type: 'text/plain' });_x000D_
var blobUrl = URL.createObjectURL(blob);_x000D_
_x000D_
var xhr = new XMLHttpRequest;_x000D_
xhr.responseType = 'blob';_x000D_
_x000D_
xhr.onload = function() {_x000D_
   var recoveredBlob = xhr.response;_x000D_
_x000D_
   var reader = new FileReader;_x000D_
_x000D_
   reader.onload = function() {_x000D_
     var blobAsDataUrl = reader.result;_x000D_
     window.location = blobAsDataUrl;_x000D_
   };_x000D_
_x000D_
   reader.readAsDataURL(recoveredBlob);_x000D_
};_x000D_
_x000D_
xhr.open('GET', blobUrl);_x000D_
xhr.send();

data: URLs are probably not what you mean by "normal" and can be problematically large. However they do work like normal URLs in that they can be shared; they're not specific to the current browser or session.

i personally use the jquery dump plugin alot to dump objects, its a bit similar to php's print_r() function Basic usage:

var obj = {
            hubba: "Some string...",
            bubba: 12.5,
            dubba: ["One", "Two", "Three"]
        }
$("#dump").append($.dump(obj));
/* will return:
Object { 
     hubba: "Some string..."
     bubba: 12.5
     dubba: Array ( 
          0 => "One"
          1 => "Two"
          2 => "Three"
     )
}
*/

Its very human readable, i also recommend this site http://json.parser.online.fr/ for creating/parsing/reading json, because it has nice colors

You just change following line in /etc/phpmyadmin/config.inc.php

$ Cfg ['Servers'] [$ i] ['table_uiprefs'] = ‘pma_table_uiprefs’;

to

$ cfg ['Servers'] [$ i] ['pma__table_uiprefs'] = ‘pma__table_uiprefs’;

And restart apache server with command,

sudo service apache2 restart

The standard MIME type for ZIP files is application/zip. The types for the files inside the ZIP does not matter for the MIME type.

As @Charles says, git mv is a shorthand.

The real question here is "Other version control systems (eg. Subversion and Perforce) treat file renames specially. Why doesn't Git?"

Linus explains at http://permalink.gmane.org/gmane.comp.version-control.git/217 with characteristic tact:

Please stop this "track files" crap. Git tracks exactly what matters, namely "collections of files". Nothing else is relevant, and even thinking that it is relevant only limits your world-view. Notice how the notion of CVS "annotate" always inevitably ends up limiting how people use it. I think it's a totally useless piece of crap, and I've described something that I think is a million times more useful, and it all fell out exactly because I'm not limiting my thinking to the wrong model of the world.

In our case it was an empty AndroidManifest.xml.

While upgrading Eclispe we ran into the usual trouble, and AndroidManifest.xml must have been checked into SVN by the build script after being clobbered.

Found it by compiling from inside Eclipse, instead of from the command line.

If efficiency is an issue and you have to build multiple different n-grams (up to a hundred as you say), but you want to use pure python I would do:

from itertools import chain

def n_grams(seq, n=1):
    """Returns an itirator over the n-grams given a listTokens"""
    shiftToken = lambda i: (el for j,el in enumerate(seq) if j>=i)
    shiftedTokens = (shiftToken(i) for i in range(n))
    tupleNGrams = zip(*shiftedTokens)
    return tupleNGrams # if join in generator : (" ".join(i) for i in tupleNGrams)

def range_ngrams(listTokens, ngramRange=(1,2)):
    """Returns an itirator over all n-grams for n in range(ngramRange) given a listTokens."""
    return chain(*(n_grams(listTokens, i) for i in range(*ngramRange)))

Usage :

>>> input_list = input_list = 'test the ngrams generator'.split()
>>> list(range_ngrams(input_list, ngramRange=(1,3)))
[('test',), ('the',), ('ngrams',), ('generator',), ('test', 'the'), ('the', 'ngrams'), ('ngrams', 'generator'), ('test', 'the', 'ngrams'), ('the', 'ngrams', 'generator')]

~Same speed as NLTK:

import nltk

input_list = 'test the ngrams interator vs nltk '*10**6
nltk.ngrams(input_list,n=5)
# 7.02 ms ± 79 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Repost from my previous answer.

The primary purpose of AF_INET was to allow for other possible network protocols or address families (AF is for address family; PF_INET is for the (IPv4) internet protocol family). For example, there probably are a few Netware SPX/IPX networks around still; there were other network systems like DECNet, StarLAN and SNA, not to mention the ill-begotten ISO OSI (Open Systems Interconnection), and these did not necessarily use the now ubiquitous IP address to identify the peer host in network connections.

The ubiquitous alternative to AF_INET (which, in retrospect, should have been named AF_INET4) is AF_INET6, for the IPv6 address family. IPv4 uses 32-bit addresses; IPv6 uses 128-bit addresses.

You may see some other values - but they are unusual. It is there to allow for alternatives and future directions. The sockets interface is actually very general indeed - which is one of the reasons it has thrived where other networking interfaces have withered.

Life has (mostly) gotten simpler - be grateful.

On the xkcd note, the Bobby Tables website has good advice for avoiding the improper interpretation of user data (in this case, the string "Null") in SQL queries in various languages, including ColdFusion.

It is not clear from the question that this is the source of the problem, and given the solution noted in a comment to the first answer (embedding the parameters in a structure) it seems likely that it was something else.

Just as Jake Wilson said: You can set the connection to a variable then disconnect it when you are done:

let db;
mongoose.connect('mongodb://localhost:27017/somedb').then((dbConnection)=>{
    db = dbConnection;
    afterwards();
});


function afterwards(){

    //do stuff

    db.disconnect();
}

or if inside Async function:

(async ()=>{
    const db = await mongoose.connect('mongodb://localhost:27017/somedb', { useMongoClient: 
                  true })

    //do stuff

    db.disconnect()
})

otherwise when i was checking it in my environment it has an error.

You should install Google Drivers from: http://developer.android.com/sdk/win-usb.html#top That works for me every time

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

Have a look at this link: http://php.net/manual/en/pdostatement.rowcount.php It is not recommended to use rowCount() in SELECT statements!

To be honest, the comments accompanying the prototypes seem clear enough. Something like this should do the trick:

void compute_md5(char *str, unsigned char digest[16]) {
    MD5Context ctx;
    MD5Init(&ctx);
    MD5Update(&ctx, str, strlen(str));
    MD5Final(digest, &ctx);
}

where str is a C string you want the hash of, and digest is the resulting MD5 digest.

I know this is an old thread, but I stumbled across it and thought I'd share my method which I have found to be a very fast way to use find to find only non-binary files:

find . -type f -exec grep -Iq . {} \; -print

The -I option to grep tells it to immediately ignore binary files and the . option along with the -q will make it immediately match text files so it goes very fast. You can change the -print to a -print0 for piping into an xargs -0 or something if you are concerned about spaces (thanks for the tip, @lucas.werkmeister!)

Also the first dot is only necessary for certain BSD versions of find such as on OS X, but it doesn't hurt anything just having it there all the time if you want to put this in an alias or something.

EDIT: As @ruslan correctly pointed out, the -and can be omitted since it is implied.

Java creates a String object for each string literal you use in your code. Any time "" is used, it is the same as calling new String().

Strings are complex data that just "act" like primitive data. String literals are actually objects even though we pretend they're primitive literals, like 6, 6.0, 'c', etc. So the String "literal" "text" returns a new String object with value char[] value = {'t','e','x','t}. Therefore, calling

new String("text"); 

is actually akin to calling

new String(new String(new char[]{'t','e','x','t'}));

Hopefully from here, you can see why your textbook considers this redundant.

For reference, here is the implementation of String: http://www.docjar.com/html/api/java/lang/String.java.html

It's a fun read and might inspire some insight. It's also great for beginners to read and try to understand, as the code demonstrates very professional and convention-compliant code.

Another good reference is the Java tutorial on Strings: http://docs.oracle.com/javase/tutorial/java/data/strings.html

You need to use Inlines:

<TextBlock.Inlines>
    <Run FontWeight="Bold" FontSize="14" Text="This is WPF TextBlock Example. " />
    <Run FontStyle="Italic" Foreground="Red" Text="This is red text. " />
</TextBlock.Inlines>

With binding:

<TextBlock.Inlines>
    <Run FontWeight="Bold" FontSize="14" Text="{Binding BoldText}" />
    <Run FontStyle="Italic" Foreground="Red" Text="{Binding ItalicText}" />
</TextBlock.Inlines>

You can also bind the other properties:

<TextBlock.Inlines>
    <Run FontWeight="{Binding Weight}"
         FontSize="{Binding Size}"
         Text="{Binding LineOne}" />
    <Run FontStyle="{Binding Style}"
         Foreground="Binding Colour}"
         Text="{Binding LineTwo}" />
</TextBlock.Inlines>

You can bind through converters if you have bold as a boolean (say).

select * from tbl where (endDate>=@starDate and startDate<=@endDate)

attached the diagram for explanation

storing simple data in DB StartDate =10/01/2020 and endDate=20/01/2020. user can provide @startDate(d1) and @endDate(d2) to search.

here 6 scenarios can happen depicted by the 4 red lines (match data) 2 green lines (no match data).

so by conclusion from the image, to get data from DB by providing d1,d2. ED must be greater than d1(@startDate) and SD must be less than d2(@endDate).

I know the thread is already all, but as I was checking through I've come up with a solution (code listed below). Hope it can help.

#include <iostream>
#include <vector>

class Box
{
    public:

    static int BoxesTotal;
    static int BoxesEver;
    int Id;

    Box()
    {
        ++BoxesTotal;
        ++BoxesEver;
        Id = BoxesEver;
        std::cout << "Box (" << Id << "/" << BoxesTotal << "/" << BoxesEver << ") initialized." << std::endl;
    }

    ~Box()
    {
        std::cout << "Box (" << Id << "/" << BoxesTotal << "/" << BoxesEver << ") ended." << std::endl;
        --BoxesTotal;
    }

};

int Box::BoxesTotal = 0;
int Box::BoxesEver = 0;

int main(int argc, char* argv[])
{
    std::cout << "Objects (Boxes) example." << std::endl;
    std::cout << "------------------------" << std::endl;

    std::vector <Box*> BoxesTab;

    Box* Indicator;
    for (int i = 1; i<4; ++i)
    {
        std::cout << "i = " << i << ":" << std::endl;
        Box* Indicator = new(Box);
        BoxesTab.push_back(Indicator);
        std::cout << "Adres Blowera: " <<  BoxesTab[i-1] << std::endl;
    }

    std::cout << "Summary" << std::endl;
    std::cout << "-------" << std::endl;
    for (int i=0; i<3; ++i)
    {
        std::cout << "Adres Blowera: " <<  BoxesTab[i] << std::endl;
    }

    std::cout << "Deleting" << std::endl;
    std::cout << "--------" << std::endl;
    for (int i=0; i<3; ++i)
    {
        std::cout << "Deleting Box: " << i+1 << " (" <<  BoxesTab[i] << ") " << std::endl;
        Indicator = (BoxesTab[i]);
        delete(Indicator);
    }

    return 0;
}

And the result it produces is:

Objects (Boxes) example.
------------------------
i = 1:
Box (1/1/1) initialized.
Adres Blowera: 0xdf8ca0
i = 2:
Box (2/2/2) initialized.
Adres Blowera: 0xdf8ce0
i = 3:
Box (3/3/3) initialized.
Adres Blowera: 0xdf8cc0

Deleting Box: 1 (0xdf8ca0) 
Box (1/3/3) ended.
Deleting Box: 2 (0xdf8ce0) 
Box (2/2/3) ended.
Deleting Box: 3 (0xdf8cc0) 
Box (3/1/3) ended.

I found way for Print Log in Retrofit

OkHttpClient okHttpClient = new OkHttpClient.Builder()
            .addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Request request = chain.request();
                    if (BuildConfig.DEBUG) {
                        Log.e(getClass().getName(), request.method() + " " + request.url());
                        Log.e(getClass().getName(), "" + request.header("Cookie"));
                        RequestBody rb = request.body();
                        Buffer buffer = new Buffer();
                        if (rb != null)
                            rb.writeTo(buffer);
                        LogUtils.LOGE(getClass().getName(), "Payload- " + buffer.readUtf8());
                    }
                    return chain.proceed(request);
                }
            })
            .readTimeout(60, TimeUnit.SECONDS)
            .connectTimeout(60, TimeUnit.SECONDS)
            .build();

            iServices = new Retrofit.Builder()
                    .baseUrl("Your Base URL")
                    .client(okHttpClient)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build()
                    .create(Your Service Interface .class);

Works for me.

feedgnuplot is another front end to gnuplot, which handles piping in data.

You can always use the stl:

auto min_value = *std::min_element(v.begin(),v.end());

Something like this could be useful:

char str[] = "0x1800785";
int num;

sscanf(str, "%x", &num);
printf("0x%x %i\n", num, num); 

Read man sscanf

If you wish to have your config file on a different path you have to give your service a name:

mysqld --install NAME --defaults-file=C:\my-opts2.cnf

You can also use the name to install multiple mysql services listening on different sockets if you need that for some reason. You can see why it's failing by copying the execution path and adding --console to the end in the terminal. Finally, you can modify the starting path of a service by regediting:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NAME

That works well but it isn't as useful because the windows service mechanism provides little logging capabilities.

/**

public static boolean isEmailValid(String email) {
    String expression = "^[\\w\\.-]+@([\\w\\-]+\\.)+[A-Z]{2,4}$";
    Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(email);
    return matcher.matches();

Pass your edit text string in this function .

for right email verification you need server side authentication

Note there is now a built-in method in Android, see answers below.

in Bitbucket go to branches in left hand side menu.

1. Select your branch you want to delete.
2. Go to action column, click on three dots (...) and select delete.

If you have several threads executing the methods m1 and m2 in the code below:

class SomeClass {
    private int i = 0;

    public void m1() { i = 5; }
    public int m2() { return i; }
}

you have the guarantee that any thread calling m2 will either read 0 or 5.

On the other hand, with this code (where i is a long):

class SomeClass {
    private long i = 0;

    public void m1() { i = 1234567890L; }
    public long m2() { return i; }
}

a thread calling m2 could read 0, 1234567890L, or some other random value because the statement i = 1234567890L is not guaranteed to be atomic for a long (a JVM could write the first 32 bits and the last 32 bits in two operations and a thread might observe i in between).

public static void main(String[] args) {

    int[] A=new int[size];
      //code for take input in array
      int[] C=sorting(A); //pass array via method
      //and then print array

    }
public static int[] sorting(int[] a) {
     //code for work with array 
     return a; //retuen array
}

I'm using nnoremap in my .vimrc

To single quote a word:

nnoremap sq :silent! normal mpea'<Esc>bi'<Esc>`pl

To remove quotes (works on double quotes as well):

nnoremap qs :silent! normal mpeld bhd `ph<CR>

Rule to remember: 'sq' = single quote.

Your second attempt failed primarily because you named the CTE same as the underlying table and made the CTE look as if it was a recursive CTE, because it essentially referenced itself. A recursive CTE must have a specific structure which requires the use of the UNION ALL set operator.

Instead, you could just have given the CTE a different name as well as added the target column to it:

With SomeName As
(
SELECT 
CODE_DEST,
ROW_NUMBER() OVER (ORDER BY [RS_NOM] DESC) AS RN
FROM DESTINATAIRE_TEMP
)
UPDATE SomeName SET CODE_DEST=RN

you have to put this in web.config :

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="50000000" />
      </webServices>
    </scripting>
  </system.web.extensions>

I simply:

rm -rf ~/anaconda3

...this removed conda also.

Then:

mousepad ~/.bashrc

...and removed the path line added at the very bottom (clearly identified by Anaconda as 'added by Anaconda'.

Worth noting that anaconda3 created a backup of my .bashrc file before modification, and named it as:

./bashrc-anaconda3.bak

...so I could always have just renamed this and deleted my modified .bashrc

 byte[] bytes = { 1,2,3,4 };

 string stringByte= BitConverter.ToString(bytes);

 Console.WriteLine(stringByte);

For the most part you treat it as if you are validating any other kind of control but use the InitialValue property of the required field validator.

<asp:RequiredFieldValidator ID="rfv1" runat="server" ControlToValidate="your-dropdownlist" InitialValue="Please select" ErrorMessage="Please select something" />

Basically what it's saying is that validation will succeed if any other value than the 1 set in InitialValue is selected in the dropdownlist.

If databinding you will need to insert the "Please select" value afterwards as follows

this.ddl1.Items.Insert(0, "Please select");

I had the same problem. Even after updating the password using sudo passwd it was not working. I had to give "multiple" roles for my user through IAM & Admin Refer Screen Shot on IAM & Admin screen of google cloud

After that i restarted the VM. Then again changed the password and then it worked.

user1@sap-hanaexpress-public-1-vm:~> sudo passwd
New password: 
Retype new password: 
passwd: password updated successfully
user1@sap-hanaexpress-public-1-vm:~> su
Password: 
sap-hanaexpress-public-1-vm:/home/user1 # whoami
root
sap-hanaexpress-public-1-vm:/home/user1 #

To just get the index column names df.index.names will work for both a single Index or MultiIndex as of the most recent version of pandas.

As someone who found this while trying to find the best way to get a list of index names + column names, I would have found this answer useful:

names = list(filter(None, df.index.names + df.columns.values.tolist()))

This works for no index, single column Index, or MultiIndex. It avoids calling reset_index() which has an unnecessary performance hit for such a simple operation. I'm surprised there isn't a built in method for this (that I've come across). I guess I run into needing this more often because I'm shuttling data from databases where the dataframe index maps to a primary/unique key, but is really just another column to me.

If your whitespace is consistent you could use that as a delimiter, also instead of inserting \t directly, you could set the output separator and it will be included automatically:

< file awk -v OFS='\t' -v FS='[/ ]' '{print $3, $5, $NF}'

On OS X nothing helps poor builtin sed to become adequate. The solution is:

brew install gnu-sed

And then use gsed instead of sed, which will just work as expected.

You have to add writing rights to the directory in which your sqlite database is stored. So running chmod 664 /srv/mysite should help.

This is a security risk, so better solution is to change the owner of your database to www-data:

chown www-data:www-data /srv/mysite
chown www-data:www-data /srv/mysite/DATABASE.sqlite

Actually I merged all your answers to my own solution how to solve the above problem:

1. I create the pubxml file according my needs
2. Then I copy all the parameters from pubxml file to my own list of parameters "/p:foo=bar" for msbuild.exe
3. I throw away the pubxml file

The result is like that:

msbuild /t:restore /t:build /p:WebPublishMethod=FileSystem /p:publishUrl=C:\builds\MyProject\ /p:DeleteExistingFiles=True /p:LastUsedPlatform="Any CPU" /p:Configuration=Release

And, if you don't want to instantiate Class2, declare UpdateEmployee as static and call it like this:

Class2.UpdateEmployee();

However, you'll normally want to do what @parag said.

\d means 'digit'. + means, '1 or more times'. So \d+ means one or more digit. It will match 12 and 1.

This is the is simplest solution that worked for me.

// Start animation
linear_layout.startAnimation(slide_down); 

paramiko.SFTPClient

Sample Usage:

import paramiko
paramiko.util.log_to_file("paramiko.log")

# Open a transport
host,port = "example.com",22
transport = paramiko.Transport((host,port))

# Auth    
username,password = "bar","foo"
transport.connect(None,username,password)

# Go!    
sftp = paramiko.SFTPClient.from_transport(transport)

# Download
filepath = "/etc/passwd"
localpath = "/home/remotepasswd"
sftp.get(filepath,localpath)

# Upload
filepath = "/home/foo.jpg"
localpath = "/home/pony.jpg"
sftp.put(localpath,filepath)

# Close
if sftp: sftp.close()
if transport: transport.close()

The correct way of doing this is

<div class="row text-center">

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

Nothing helps me from all this answers, but I found the right steps (Windows 7 64 bit):

1) Open android.bat from your sdk folder for editing;

2) Add exactly this two strings:

set java_exe=c:\Program Files\Java\jdk1.8.0_25\bin\java.exe
rem call lib\find_java.bat

instead of this:

set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF

Where c:\Program Files\Java\jdk1.8.0_25 is your jdk folder. 3) Enjoy. SDK Manager will launch from Android studio IDE.

\usepackage[utf8]{inputenc} will not work for a bibliographic entry such as this:

@ARTICLE{Hardy2007,
author = {Ibn Taymiyyah, A?mad ibn ?Abd al{-}Halim},
title = {Naq? al{-}man?iq},
shorttitle = {Naq? al-man?iq},
editor = {?amzah, A?mad},
publisher = {Maktabat a{l-}Sunnah},
address = {Cairo},
year = {1970},
sortname = {IbnTaymiyyaNaqdalmantiq},
keywords = { Logic, Medieval}} 

For this entry use \usepackage[utf8x]{inputenc}

One other possible reason: in my case, I was attempting to save the child before saving the parent, on a brand new entity.

The code was something like this in a User.java model:

this.lastName = lastName;
this.isAdmin = isAdmin;
this.accountStatus = "Active";
this.setNewPassword(password);
this.timeJoin = new Date();
create();

The setNewPassword() method creates a PasswordHistory record and adds it to the history collection in User. Since the create() statement hadn't been executed yet for the parent, it was trying to save to a collection of an entity that hadn't yet been created. All I had to do to fix it was to move the setNewPassword() call after the call to create().

this.lastName = lastName;

To change your password for accessing Subversion

Typically this would be handled by your Subversion server administrator. If that's you and you are using the built-in authentication, then edit your [repository]\conf\passwd file on your Subversion server machine.

To delete locally-cached credentials

Follow these steps:

• Right-click your desktop and select TortoiseSVN->Settings
• Select Saved Data.
• Click Clear against Authentication Data.

Next time you attempt an action that requires credentials you'll be asked for them.

If you're using the command-line svn.exe use the --no-auth-cache option so that you can specify alternate credentials without having them cached against your Windows user.

It wasn't immediately obvious to me that I needed to download the helper first! I found the credential.helper download at Atlassian's Permanently authenticating with Git repositories.

Quote:

Follow these steps if you want to use Git with credential caching on OS X:

Download the binary git-credential-osxkeychain.

Run the command below to ensure the binary is executable:

chmod a+x git-credential-osxkeychain

Put it in the directory /usr/local/bin.

Run the command below:

git config --global credential.helper osxkeychain

What is RMSE? Also known as MSE, RMD, or RMS. What problem does it solve?

If you understand RMSE: (Root mean squared error), MSE: (Mean Squared Error) RMD (Root mean squared deviation) and RMS: (Root Mean Squared), then asking for a library to calculate this for you is unnecessary over-engineering. All these metrics are a single line of python code at most 2 inches long. The three metrics rmse, mse, rmd, and rms are at their core conceptually identical.

RMSE answers the question: "How similar, on average, are the numbers in list1 to list2?". The two lists must be the same size. I want to "wash out the noise between any two given elements, wash out the size of the data collected, and get a single number feel for change over time".

Intuition and ELI5 for RMSE:

Imagine you are learning to throw darts at a dart board. Every day you practice for one hour. You want to figure out if you are getting better or getting worse. So every day you make 10 throws and measure the distance between the bullseye and where your dart hit.

You make a list of those numbers list1. Use the root mean squared error between the distances at day 1 and a list2 containing all zeros. Do the same on the 2nd and nth days. What you will get is a single number that hopefully decreases over time. When your RMSE number is zero, you hit bullseyes every time. If the rmse number goes up, you are getting worse.

Example in calculating root mean squared error in python:

import numpy as np
d = [0.000, 0.166, 0.333]   #ideal target distances, these can be all zeros.
p = [0.000, 0.254, 0.998]   #your performance goes here

print("d is: " + str(["%.8f" % elem for elem in d]))
print("p is: " + str(["%.8f" % elem for elem in p]))

def rmse(predictions, targets):
    return np.sqrt(((predictions - targets) ** 2).mean())

rmse_val = rmse(np.array(d), np.array(p))
print("rms error is: " + str(rmse_val))

Which prints:

d is: ['0.00000000', '0.16600000', '0.33300000']
p is: ['0.00000000', '0.25400000', '0.99800000']
rms error between lists d and p is: 0.387284994115

The mathematical notation:

Glyph Legend: n is a whole positive integer representing the number of throws. i represents a whole positive integer counter that enumerates sum. d stands for the ideal distances, the list2 containing all zeros in above example. p stands for performance, the list1 in the above example. superscript 2 stands for numeric squared. d_i is the i'th index of d. p_i is the i'th index of p.

The rmse done in small steps so it can be understood:

def rmse(predictions, targets):

    differences = predictions - targets                       #the DIFFERENCEs.

    differences_squared = differences ** 2                    #the SQUAREs of ^

    mean_of_differences_squared = differences_squared.mean()  #the MEAN of ^

    rmse_val = np.sqrt(mean_of_differences_squared)           #ROOT of ^

    return rmse_val                                           #get the ^

How does every step of RMSE work:

Subtracting one number from another gives you the distance between them.

8 - 5 = 3         #absolute distance between 8 and 5 is +3
-20 - 10 = -30    #absolute distance between -20 and 10 is +30

If you multiply any number times itself, the result is always positive because negative times negative is positive:

3*3     = 9   = positive
-30*-30 = 900 = positive

Add them all up, but wait, then an array with many elements would have a larger error than a small array, so average them by the number of elements.

But wait, we squared them all earlier to force them positive. Undo the damage with a square root!

That leaves you with a single number that represents, on average, the distance between every value of list1 to it's corresponding element value of list2.

If the RMSE value goes down over time we are happy because variance is decreasing.

RMSE isn't the most accurate line fitting strategy, total least squares is:

Root mean squared error measures the vertical distance between the point and the line, so if your data is shaped like a banana, flat near the bottom and steep near the top, then the RMSE will report greater distances to points high, but short distances to points low when in fact the distances are equivalent. This causes a skew where the line prefers to be closer to points high than low.

If this is a problem the total least squares method fixes this: https://mubaris.com/posts/linear-regression

Gotchas that can break this RMSE function:

If there are nulls or infinity in either input list, then output rmse value is is going to not make sense. There are three strategies to deal with nulls / missing values / infinities in either list: Ignore that component, zero it out or add a best guess or a uniform random noise to all timesteps. Each remedy has its pros and cons depending on what your data means. In general ignoring any component with a missing value is preferred, but this biases the RMSE toward zero making you think performance has improved when it really hasn't. Adding random noise on a best guess could be preferred if there are lots of missing values.

In order to guarantee relative correctness of the RMSE output, you must eliminate all nulls/infinites from the input.

RMSE has zero tolerance for outlier data points which don't belong

Root mean squared error squares relies on all data being right and all are counted as equal. That means one stray point that's way out in left field is going to totally ruin the whole calculation. To handle outlier data points and dismiss their tremendous influence after a certain threshold, see Robust estimators that build in a threshold for dismissal of outliers.

For Asp.Net MVC

@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList, 
 new { 
 @class = "chosen-select form-control"
 }) 

or

  @Html.ListBoxFor(model => model.parameterName,
  ViewBag.ParameterValueList as MultiSelectList,
   new{
       data_placeholder = "Select Options ",
       @class = "chosen-select form-control"
   })

I had this problem because I didn't map all entities in orm.xml file

Here is my simplistic log4j2.xml that prints to console and writes to a daily rolling file:

// java
private static final Logger LOGGER = LogManager.getLogger(MyClass.class);

    </Loggers>
</Configuration>

TimeBasedTriggeringPolicy

interval (integer) - How often a rollover should occur based on the most specific time unit in the date pattern. For example, with a date pattern with hours as the most specific item and and increment of 4 rollovers would occur every 4 hours. The default value is 1.

modulate (boolean) - Indicates whether the interval should be adjusted to cause the next rollover to occur on the interval boundary. For example, if the item is hours, the current hour is 3 am and the interval is 4 then the first rollover will occur at 4 am and then next ones will occur at 8 am, noon, 4pm, etc.

A new log file will be created daily with previous day automatically renamed to:

In a Maven project, you would put the log4j2.xml in src/main/resources or src/test/resources.

Create a table layout panel with two columns in your form and name it tlpFields.

Then, simply add new control to table layout panel (in this case I added 5 labels in column-1 and 5 textboxes in column-2).

tlpFields.RowStyles.Clear();  //first you must clear rowStyles

for (int ii = 0; ii < 5; ii++)
{
    Label l1= new Label();
    TextBox t1 = new TextBox();

    l1.Text = "field : ";

    tlpFields.Controls.Add(l1, 0, ii);  // add label in column0
    tlpFields.Controls.Add(t1, 1, ii);  // add textbox in column1

    tlpFields.RowStyles.Add(new RowStyle(SizeType.Absolute,30)); // 30 is the rows space
}

Finally, run the code.

Private Function LoaderData(ByVal strSql As String) As DataTable
    Dim cnn As SqlConnection
    Dim dad As SqlDataAdapter

    Dim dtb As New DataTable
    cnn = New SqlConnection(My.Settings.mySqlConnectionString)
    Try
        cnn.Open()
        dad = New SqlDataAdapter(strSql, cnn)
        dad.Fill(dtb)
        cnn.Close()
        dad.Dispose()
    Catch ex As Exception
        cnn.Close()
        MsgBox(ex.Message)
    End Try
    Return dtb
End Function

You can extract the html string from the PartialViewResult object, similar to the answer to this thread:

Render a view as a string

PartialViewResult and ViewResult both derive from ViewResultBase, so the same method should work on both.

Using the code from the thread above, you would be able to use:

public ActionResult ReturnSpecialJsonIfInvalid(AwesomenessModel model)
{
    if (ModelState.IsValid)
    {
        if(Request.IsAjaxRequest())
            return PartialView("NotEvil", model);
        return View(model)
    }
    if(Request.IsAjaxRequest())
    {
        return Json(new { error = true, message = RenderViewToString(PartialView("Evil", model))});
    }
    return View(model);
}

The radio buttons are sent on form submit when they are checked only...

use isset() if true then its checked otherwise its not

Using the utility I describe here, you can have a more control over the string representation you get for your array.

String[] s = { "hello", "world" };
RichIterable<String> r = RichIterable.from(s);
r.mkString();                 // gives "hello, world"
r.mkString(" | ");            // gives "hello | world"
r.mkString("< ", ", ", " >"); // gives "< hello, world >"

Pseudo-code based on @biziclop's answer:

• Using only basic constructs: variables, arrays, if, while and for
• Functions getNode(id) and getChildren(id)
• Assuming known number of nodes N

NOTE: I use array-indexing from 1, not 0.

Breadth-first

S = Array(N)
S[1] = 1; // root id
cur = 1;
last = 1
while cur <= last
    id = S[cur]
    node = getNode(id)
    children = getChildren(id)

    n = length(children)
    for i = 1..n
        S[ last+i ] = children[i]
    end
    last = last+n
    cur = cur+1

    visit(node)
end

Depth-first

S = Array(N)
S[1] = 1; // root id
cur = 1;
while cur > 0
    id = S[cur]
    node = getNode(id)
    children = getChildren(id)

    n = length(children)
    for i = 1..n
        // assuming children are given left-to-right
        S[ cur+i-1 ] = children[ n-i+1 ] 

        // otherwise
        // S[ cur+i-1 ] = children[i] 
    end
    cur = cur+n-1

    visit(node)
end

Try the following:-

ChangeYear:- When set to true, indicates that the cells of the previous or next month indicated in the calendar of the current month can be selected. This option is used with options.showOtherMonths set to true.

YearRange:- Specifies the range of years in the year dropdown. (Default value: “-10:+10")

Example:-

$(document).ready(function() {
    $("#date").datepicker({
        changeYear:true,
        yearRange: "2005:2015"
    });
});

There is also http://appyframework.org/pod.html which takes a LibreOffice or OpenOffice document as template and can generate pdf, rtf, odt ... To generate pdf it requires a headless OOo on some server. Documentation is concise but relatively complete. http://appyframework.org/podWritingTemplates.html If you need advice, the author is rather helpful.

An quit option in the Console Panel will also clear all variables in variable explorer

Postgres has a very rich system catalog exposed via SQL tables. PG's statistics collector is a subsystem that supports collection and reporting of information about server activity.

Now to figure out the blocking PIDs you can simply query pg_stat_activity.

select pg_blocking_pids(pid) as blocked_by
from pg_stat_activity
where cardinality(pg_blocking_pids(pid)) > 0;

To, get the query corresponding to the blocking PID, you can self-join or use it as a where clause in a subquery.

SELECT query
FROM pg_stat_activity
WHERE pid IN (select unnest(pg_blocking_pids(pid)) as blocked_by from pg_stat_activity where cardinality(pg_blocking_pids(pid)) > 0);

Note: Since pg_blocking_pids(pid) returns an Integer[], so you need to unnest it before you use it in a WHERE pid IN clause.

Hunting for slow queries can be tedious sometimes, so have patience. Happy hunting.

jQuery.val() and .text() will never return 'undefined' for an empty selection. It always returns an empty string (i.e. ""). .html() will return null if the element doesn't exist though.You need to do:

if(page_name != '')

For other variables that don't come from something like jQuery.val() you would do this though:

if(typeof page_name != 'undefined')

You just have to use the typeof operator.

1.open the terminal.

2.backup your database with following command

your postgres bin - /opt/PostgreSQL/9.1/bin/

your source database server - 192.168.1.111

your backup file location and name - /home/dinesh/db/mydb.backup

your source db name - mydatabase

/opt/PostgreSQL/9.1/bin/pg_dump --host '192.168.1.111' --port 5432 --username "postgres" --no-password --format custom --blobs --file "/home/dinesh/db/mydb.backup" "mydatabase"

3.restore mydb.backup file into destination.

your destination server - localhost

your destination database name - mydatabase

create database for restore the backup.

/opt/PostgreSQL/9.1/bin/psql -h 'localhost' -p 5432 -U postgres -c "CREATE DATABASE mydatabase"

restore the backup.

/opt/PostgreSQL/9.1/bin/pg_restore --host 'localhost' --port 5432 --username "postgres" --dbname "mydatabase" --no-password --clean "/home/dinesh/db/mydb.backup"
