Programs & Examples On #Radix point

The functions have different purposes. vector::insert allows you to insert an object at a specified position in the vector, whereas vector::push_back will just stick the object on the end. See the following example:

using namespace std;
vector<int> v = {1, 3, 4};
v.insert(next(begin(v)), 2);
v.push_back(5);
// v now contains {1, 2, 3, 4, 5}

You can use insert to perform the same job as push_back with v.insert(v.end(), value).

Instead of

• paste (default spaces),
• paste0 (force the inclusion of missing NA as character) or
• unite (constrained to 2 columns and 1 separator),

I'd suggest an alternative as flexible as paste0 but more careful with NA: stringr::str_c

library(tidyverse)

# check the missing value!!
df <- tibble(
  n = c(2, 2, 8),
  s = c("aa", "aa", NA_character_),
  b = c(TRUE, FALSE, TRUE)
)

df %>% 
  mutate(
    paste = paste(n,"-",s,".",b),
    paste0 = paste0(n,"-",s,".",b),
    str_c = str_c(n,"-",s,".",b)
  ) %>% 

  # convert missing value to ""
  mutate(
    s_2=str_replace_na(s,replacement = "")
  ) %>% 
  mutate(
    str_c_2 = str_c(n,"-",s_2,".",b)
  )
#> # A tibble: 3 x 8
#>       n s     b     paste          paste0     str_c      s_2   str_c_2   
#>   <dbl> <chr> <lgl> <chr>          <chr>      <chr>      <chr> <chr>     
#> 1     2 aa    TRUE  2 - aa . TRUE  2-aa.TRUE  2-aa.TRUE  "aa"  2-aa.TRUE 
#> 2     2 aa    FALSE 2 - aa . FALSE 2-aa.FALSE 2-aa.FALSE "aa"  2-aa.FALSE
#> 3     8 <NA>  TRUE  8 - NA . TRUE  8-NA.TRUE  <NA>       ""    8-.TRUE

extra note from str_c documentation

Like most other R functions, missing values are "infectious": whenever a missing value is combined with another string the result will always be missing. Use str_replace_na() to convert NA to "NA"

Just multiply the number by 100, round, and divide the resulting number by 100.

Look into System.Threading.Timer class. I think this is what you're looking for.

The code example on MSDN seems to show this class doing very similar to what you're trying to do (check status after certain time).

The mentioned code example from the MSDN link:

using System;
using System.Threading;

class TimerExample
{
    static void Main()
    {
        // Create an AutoResetEvent to signal the timeout threshold in the
        // timer callback has been reached.
        var autoEvent = new AutoResetEvent(false);
        
        var statusChecker = new StatusChecker(10);

        // Create a timer that invokes CheckStatus after one second, 
        // and every 1/4 second thereafter.
        Console.WriteLine("{0:h:mm:ss.fff} Creating timer.\n", 
                        DateTime.Now);
        var stateTimer = new Timer(statusChecker.CheckStatus, 
                                autoEvent, 1000, 250);

        // When autoEvent signals, change the period to every half second.
        autoEvent.WaitOne();
        stateTimer.Change(0, 500);
        Console.WriteLine("\nChanging period to .5 seconds.\n");

        // When autoEvent signals the second time, dispose of the timer.
        autoEvent.WaitOne();
        stateTimer.Dispose();
        Console.WriteLine("\nDestroying timer.");
    }
}

class StatusChecker
{
    private int invokeCount;
    private int  maxCount;

    public StatusChecker(int count)
    {
        invokeCount  = 0;
        maxCount = count;
    }

    // This method is called by the timer delegate.
    public void CheckStatus(Object stateInfo)
    {
        AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
        Console.WriteLine("{0} Checking status {1,2}.", 
            DateTime.Now.ToString("h:mm:ss.fff"), 
            (++invokeCount).ToString());

        if(invokeCount == maxCount)
        {
            // Reset the counter and signal the waiting thread.
            invokeCount = 0;
            autoEvent.Set();
        }
    }
}
// The example displays output like the following:
//       11:59:54.202 Creating timer.
//       
//       11:59:55.217 Checking status  1.
//       11:59:55.466 Checking status  2.
//       11:59:55.716 Checking status  3.
//       11:59:55.968 Checking status  4.
//       11:59:56.218 Checking status  5.
//       11:59:56.470 Checking status  6.
//       11:59:56.722 Checking status  7.
//       11:59:56.972 Checking status  8.
//       11:59:57.223 Checking status  9.
//       11:59:57.473 Checking status 10.
//       
//       Changing period to .5 seconds.
//       
//       11:59:57.474 Checking status  1.
//       11:59:57.976 Checking status  2.
//       11:59:58.476 Checking status  3.
//       11:59:58.977 Checking status  4.
//       11:59:59.477 Checking status  5.
//       11:59:59.977 Checking status  6.
//       12:00:00.478 Checking status  7.
//       12:00:00.980 Checking status  8.
//       12:00:01.481 Checking status  9.
//       12:00:01.981 Checking status 10.
//       
//       Destroying timer.

I think 2 update calls should do

update VersionedFields
set Value = replace(value,'<iframe','<a><iframe')

update VersionedFields
set Value = replace(value,'> </iframe>','</a>')

This code will let you have a variable number of rows (with a variable number of DIVs on each row) and it will make all of the DIVs on each row match the height of its tallest neighbour:

If we assumed all the DIVs, that are floating, are inside a container with the id "divContainer", then you could use the following:

$(document).ready(function() {

var currentTallest = 0;
var currentRowStart = 0;
var rowDivs = new Array();

$('div#divContainer div').each(function(index) {

    if(currentRowStart != $(this).position().top) {

        // we just came to a new row.  Set all the heights on the completed row
        for(currentDiv = 0 ; currentDiv < rowDivs.length ; currentDiv++) rowDivs[currentDiv].height(currentTallest);

        // set the variables for the new row
        rowDivs.length = 0; // empty the array
        currentRowStart = $(this).position().top;
        currentTallest = $(this).height();
        rowDivs.push($(this));

    } else {

        // another div on the current row.  Add it to the list and check if it's taller
        rowDivs.push($(this));
        currentTallest = (currentTallest < $(this).height()) ? ($(this).height()) : (currentTallest);

    }
    // do the last row
    for(currentDiv = 0 ; currentDiv < rowDivs.length ; currentDiv++) rowDivs[currentDiv].height(currentTallest);

});
});

From what the other answers have proposed, I believe this might help:

var object = ips[ipId];
var name = "Joe";
var anothername = "Fred";
var value = "Thingy";
var anothervalue = "Fingy";
object[name] = value;
object[anothername] = anothervalue;

However, this is not tested, just an assumption based on the constant repetition of:

object["string"] = value;
//object = {string: value}

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

This should work:

function valthisform()
{
    var checkboxs=document.getElementsByName("c1");
    var okay=false;
    for(var i=0,l=checkboxs.length;i<l;i++)
    {
        if(checkboxs[i].checked)
        {
            okay=true;
            break;
        }
    }
    if(okay)alert("Thank you for checking a checkbox");
    else alert("Please check a checkbox");
}

If you have a question about the code, just comment.

^{I use l=checkboxs.length to improve the performance. See http://www.erichynds.com/javascript/javascript-loop-performance-caching-the-length-property-of-an-array/}

I'd recommend the Range object's AutoFill method for this:

rngSource.AutoFill Destination:=rngDest

Specify the Source range that contains the values or formulas you want to fill down, and the Destination range as the whole range that you want the cells filled to. The Destination range must include the Source range. You can fill across as well as down.

It works exactly the same way as it would if you manually "dragged" the cells at the corner with the mouse; absolute and relative formulas work as expected.

Here's an example:

'Set some example values'
Range("A1").Value = "1"
Range("B1").Formula = "=NOW()"
Range("C1").Formula = "=B1+A1"

'AutoFill the values / formulas to row 20'
Range("A1:C1").AutoFill Destination:=Range("A1:C20")

Hope this helps.

I know I am very late to the party, but I finaly found out how we can register the MaxLengthAttribute.

First we need a validator:

public class MaxLengthClientValidator : DataAnnotationsModelValidator<MaxLengthAttribute>
{
    private readonly string _errorMessage;
    private readonly int _length;


    public MaxLengthClientValidator(ModelMetadata metadata, ControllerContext context, MaxLengthAttribute attribute)
    : base(metadata, context, attribute)
    {
        _errorMessage = attribute.FormatErrorMessage(metadata.DisplayName);
        _length = attribute.Length;
    }

    public override IEnumerable<ModelClientValidationRule> GetClientValidationRules()
    {
        var rule = new ModelClientValidationRule
        {
            ErrorMessage = _errorMessage,
            ValidationType = "length"
        };

        rule.ValidationParameters["max"] = _length;
        yield return rule;
    }
}

Nothing realy special. In the constructor we save some values from the attribute. In the GetClientValidationRules we set a rule. ValidationType = "length" is mapped to data-val-length by the framework. rule.ValidationParameters["max"] is for the data-val-length-max attribute.

Now since you have a validator, you only need to register it in global.asax:

protected void Application_Start()
{
    //...

    //Register Validator
    DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(MaxLengthAttribute), typeof(MaxLengthClientValidator));
}

Et voila, it just works.

Most of the answers are correct but I want to add little more. The ternary operator is right-associative, which means it can be chained in the following way if … else-if … else-if … else :

function example() {
    return condition1 ? value1
         : condition2 ? value2
         : condition3 ? value3
         : value4;
}

Equivalent to:

function example() {
    if (condition1) { return value1; }
    else if (condition2) { return value2; }
    else if (condition3) { return value3; }
    else { return value4; }
}

More details is here

The fastest way is to do a*a or a**2 or np.square(a) whereas np.power(a, 2) showed to be considerably slower.

np.power() allows you to use different exponents for each element if instead of 2 you pass another array of exponents. From the comments of @GarethRees I just learned that this function will give you different results than a**2 or a*a, which become important in cases where you have small tolerances.

I've timed some examples using NumPy 1.9.0 MKL 64 bit, and the results are shown below:

In [29]: a = np.random.random((1000, 1000))

In [30]: timeit a*a
100 loops, best of 3: 2.78 ms per loop

In [31]: timeit a**2
100 loops, best of 3: 2.77 ms per loop

In [32]: timeit np.power(a, 2)
10 loops, best of 3: 71.3 ms per loop

The way I do it, taking advantage of some modern C# features:

Option 1)

public static class Utils {
    public static bool IsNullOrEmpty<T>(this IEnumerable<T> list) {
        return !(list?.Any() ?? false);
    }
}

Option 2)

public static class Utils {
    public static bool IsNullOrEmpty<T>(this IEnumerable<T> list) {
        return !(list?.Any()).GetValueOrDefault();
    }
}

And by the way, never use Count == 0 or Count() == 0 just to check if a collection is empty. Always use Linq's .Any()

This is the hardware serial number. To access it on

• Android Q (>= SDK 29) android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE is required. Only system apps can require this permission. If the calling package is the device or profile owner then the READ_PHONE_STATE permission suffices.

• Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using android.os.Build.SERIAL returns android.os.Build.UNKNOWN.

• Android 7.1 and earlier (<= SDK 25) and earlier android.os.Build.SERIAL does return a valid serial.

It's unique for any device. If you are looking for possibilities on how to get/use a unique device id you should read here.

For a solution involving reflection without requiring a permission see this answer.

I was getting this problem while using a tunnel because I:

1. had the tunnel url:port set in the FB app settings
2. but was accessing the local server by pointing my browser to "http://localhost:3000"

once i started punching the tunnel url:port into the browser, i was good to go.

i'm using Rails and Facebooker, but might help others just the same.

If you paste

A.do() {
  if (condition1) {
   X.doSomething
  } else if (condition2) {
   Y.doSomethingElse
  } else {
   donotDoAnything
  }
}

You must make your foreign key nullable:

public class User
{
    public int Id { get; set; }
    public int? CountryId { get; set; }
    public virtual Country Country { get; set; }
}

You can decode it to str with receive.decode('utf_8').

You can also use lib-auto

 xmlns:app="http://schemas.android.com/apk/lib-auto"

pyPDF works fine (assuming that you're working with well-formed PDFs). If all you want is the text (with spaces), you can just do:

import pyPdf
pdf = pyPdf.PdfFileReader(open(filename, "rb"))
for page in pdf.pages:
    print page.extractText()

You can also easily get access to the metadata, image data, and so forth.

A comment in the extractText code notes:

Locate all text drawing commands, in the order they are provided in the content stream, and extract the text. This works well for some PDF files, but poorly for others, depending on the generator used. This will be refined in the future. Do not rely on the order of text coming out of this function, as it will change if this function is made more sophisticated.

Whether or not this is a problem depends on what you're doing with the text (e.g. if the order doesn't matter, it's fine, or if the generator adds text to the stream in the order it will be displayed, it's fine). I have pyPdf extraction code in daily use, without any problems.

A fast solution is using the gnu utility truncate:

[ -z $(tail -c1 file) ] && truncate -s-1 file

The test will be true if the file does have a trailing new line.

The removal is very fast, truly in place, no new file is needed and the search is also reading from the end just one byte (tail -c1).

Try changing the app/config/email.php

smtp to mail

you can use ? at the end to skip one "\"

regex("\\\\?")

You could also use a CSS "calc" to get the same effect instead of using the negative margin or transform properties (in case you want to use those properties for anything else).

.hero:after,
.hero:after {
    z-index: -1;
    position: absolute;
    top: 98.1%;
    left: calc(50% - 25px);
    content: '';
    width: 0;
    height: 0;
    border-top: solid 50px #e15915;
    border-left: solid 50px transparent;
    border-right: solid 50px transparent;
}

for me the "workaround" solution was to remove the "_normal" from the end of the string

Check it out below:

In Mvc 4 you can use AcceptVerbsAttribute, I think this is a very clean solution

[AcceptVerbs(WebRequestMethods.Http.Get, WebRequestMethods.Http.Post)]
public IHttpActionResult Login()
{
   // Login logic
}

Config file:

worker_processes  4;  # 2 * Number of CPUs

events {
    worker_connections  19000;  # It's the key to high performance - have a lot of connections available
}

worker_rlimit_nofile    20000;  # Each connection needs a filehandle (or 2 if you are proxying)


# Total amount of users you can serve = worker_processes * worker_connections

I know some things have changed in AC 2010. However, the old-fashioned ADODB is, as far as I know, the best way to go in VBA. An Example:

Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim prm As ADODB.Parameter
Dim rs As ADODB.Recordset
Dim colReturn As New Collection

Dim SQL As String
SQL = _
    "SELECT c.ClientID, c.LastName, c.FirstName, c.MI, c.DOB, c.SSN, " & _
    "c.RaceID, c.EthnicityID, c.GenderID, c.Deleted, c.RecordDate " & _
    "FROM tblClient AS c " & _
    "WHERE c.ClientID = @ClientID"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

With cn
    .Provider = DataConnection.MyADOProvider
    .ConnectionString = DataConnection.MyADOConnectionString
    .Open
End With

With cmd
    .CommandText = SQL
    .ActiveConnection = cn
    Set prm = .CreateParameter("@ClientID", adInteger, adParamInput, , mlngClientID)
    .Parameters.Append prm
End With

Set rs = cmd.Execute

With rs
    If Not .EOF Then
        Do Until .EOF
            mstrLastName = Nz(!LastName, "")
            mstrFirstName = Nz(!FirstName, "")
            mstrMI = Nz(!MI, "")
            mdDOB = !DOB
            mstrSSN = Nz(!SSN, "")
            mlngRaceID = Nz(!RaceID, -1)
            mlngEthnicityID = Nz(!EthnicityID, -1)
            mlngGenderID = Nz(!GenderID, -1)
            mbooDeleted = Deleted
            mdRecordDate = Nz(!RecordDate, "")

            .MoveNext
        Loop
    End If
    .Close
End With

cn.Close

Set rs = Nothing
Set cn = Nothing

Below is my simple approach to the issue.

JQuery function:

jQuery.fn.trackClicks = function () {
    if ($(this).attr("data-clicks") === undefined) $(this).attr("data-clicks", 0);

    var timer;
    $(this).click(function () {
        $(this).attr("data-clicks", parseInt($(this).attr("data-clicks")) + 1);

        if (timer) clearTimeout(timer);

        var item = $(this);
        timer = setTimeout(function() {
            item.attr("data-clicks", 0);
        }, 1000);
    });
}

Implementation:

$(function () {
    $("a").trackClicks();

    $("a").click(function () {
        if ($(this).attr("data-clicks") === "2") {
            // Double clicked
        }
    });
});

Inspect the clicked element in Firefox/Chrome to see data-clicks go up and down as you click, adjust time (1000) to suit.

One way is (this is with Bash)

grep -P '\t'

-P turns on Perl regular expressions so \t will work.

As user unwind says, it may be specific to GNU grep. The alternative is to literally insert a tab in there if the shell, editor or terminal will allow it.

In my case, this causes error:

return response->json(["message" => "Model status successfully updated!", "data" => $model], 200);

but this not:

return response->json(["message" => "Model status successfully updated!", "data" => $model->toJson()], 200);

I've written a tutorial that expands on the answer posted by JVitela. Basically, it uses the same idea, but instead of rendering each string to a texture, it renders all characters from a font file to a texture and uses that to allow for full dynamic text rendering with no further slowdowns (once the initialization is complete).

The main advantage of my method, compared to the various font atlas generators, is that you can ship small font files (.ttf .otf) with your project instead of having to ship large bitmaps for every font variation and size. It can generate perfect quality fonts at any resolution using only a font file :)

The tutorial includes full code that can be used in any project :)

data = []
n = int(raw_input('Enter how many elements you want: '))
for i in range(0, n):
    x = raw_input('Enter the numbers into the array: ')
    data.append(x)
print(data)

Now this doesn't do any error checking and it stores data as a string.

I've found this to work for me:

to hide:

$('.mapWrapper')
.css({
  visibility: 'hidden',
  height: 0
});

to show:

    $('.mapWrapper').css({
      visibility: 'visible',
      height: 'auto'
    });

The posted answers are very good when working with data.frames. However, these tasks can be pretty inefficient from a memory perspective. With large data, removing a column can take an unusually long amount of time and/or fail due to out of memory errors. Package data.table helps address this problem with the := operator:

library(data.table)
> dt <- data.table(a = 1, b = 1, c = 1)
> dt[,a:=NULL]
     b c
[1,] 1 1

I should put together a bigger example to show the differences. I'll update this answer at some point with that.

Swift 3+

button.setImage(UIImage(named: "selected_image"), for: [.selected, .highlighted])

OR

button.setImage(UIImage(named: "selected_image"), for: UIControlState.selected.union(.highlighted))

It means that the button current in selected state, then you touch it, show the highlight state.

I've seen various suggestions how code can find out whether it runs on the emulator, but none are quite satisfactory, or "future-proof". For the time being I've settled on reading the device ID, which is all zeros for the emulator:

TelephonyManager telmgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); boolean isEmulator = "000000000000000".equals(telmgr.getDeviceId());

But on a deployed app that requires the READ_PHONE_STATE permission

Linkage. Try this:

extern "C" void *print_message() {...

You can increase body size in nginx configuration file as

sudo nano /etc/nginx/nginx.conf

client_max_body_size 100M;

Restart nginx to apply the changes.

sudo service nginx restart

I have found that this error can occur in DESIGN MODE as opposed to ? execution mode... If you are doing something such as creating a class member which requires access to an .INI or .HTM file (configuration file, help file) you might want to NOT initialize the item in the declaration, but initialize it later in FORM_Load() etc... When you DO initialize... Use a guard IF statement:

    /// <summary>FORM: BasicApp - Load</summary>
    private void BasicApp_Load(object sender, EventArgs e)
    {
        // Setup Main Form Caption with App Name and Config Control Info
        if (!DesignMode)
        {
            m_Globals = new Globals();
            Text = TGG.GetApplicationConfigInfo();
        }
    }

This will keep the MSVS Designer from trying to create an INI or HTM file when you are in design mode.

I had to use un function which finds every elements in an array. So I modified the function done by Jakub Trunecek as follow:

function search_in_array_r($needle, $array) {
    $found = array();
    foreach ($array as $key => $val) {
        if ($val[1] == $needle) {
            array_push($found, $val[1]);
        }
    }
    if (count($found) != 0)
        return $found;
    else
        return null;
}

<font color="red">This is some text!</font> 

This worked the best for me when I only wanted to change one word into the color red in a sentence.

For Expose.class Error i.e

Hope this helps. Good luck!

As a refinement of simplest solution, and if you can’t or don’t want to install Powershell, just run:

dir /s /b | sort /r /+261 > out.txt

or (faster):

dir /s /b | sort /r /+261 /o out.txt

And lines longer than 260 will get to the top of listing. Note that you must add 1 to SORT column parameter (/+n).

On my Slovenian keyboard it is ALT    + Ð

First you have to install a module call Serial. To do that go to the folder call Scripts which is located in python installed folder. If you are using Python 3 version it's normally located in location below,

C:\Python34\Scripts  

Once you open that folder right click on that folder with shift key. Then click on 'open command window here'. After that cmd will pop up. Write the below code in that cmd window,

pip install PySerial

and press enter.after that PySerial module will be installed. Remember to install the module u must have an INTERNET connection.

after successfully installed the module open python IDLE and write down the bellow code and run it.

import serial
# "COM11" is the port that your Arduino board is connected.set it to port that your are using        
ser = serial.Serial("COM11", 9600)
while True:
    cc=str(ser.readline())
    print(cc[2:][:-5])   

You need to click Log Navigator icon (far right in left sidebar). Then choose your Debug/Run session in left sidebar, and you will have console in editor area.

If all you want to do is store some static values in a lookup table, you can use an Object Literal (the same format used by JSON) to do it compactly:

var table = { one: [1,10,5], two: [2], three: [3, 30, 300] }

And then access them using JavaScript's associative array syntax:

alert(table['one']);    // Will alert with [1,10,5]
alert(table['one'][1]); // Will alert with 10

I could be wrong because I've never used Angular, but I believe you are probably using ng-bind, which will create just a TextNode.

You will want to use ng-bind-html instead.

http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml

Update: It looks like you'll need to use ng-bind-html-unsafe='q.category'

http://docs.angularjs.org/api/ng.directive:ngBindHtmlUnsafe

Here's a demo:

Tcpdf is also a good liabrary for generating pdf in php http://www.tcpdf.org/

Unsure what dbms you're using however I'd do it this way in Microsoft SQL:

select      [date]
from        tbemp 
order by    cast([date] as datetime) asc

For that kind of behavior I always use the jQueryUI button widget, I use it for links and buttons.

Define the tag within HTML:

<button id="sampleButton">Sample Button</button>
<a id="linkButton" href="yourHttpReferenceHere">Link Button</a>

Use jQuery to initialize the buttons:

$("#sampleButton").button();
$("#linkButton").button();

Use the button widget methods to disable/enable them:

$("#sampleButton").button("enable"); //enable the button
$("#linkButton").button("disable"); //disable the button

That will take care of the button and cursor behavior, but if you need to get deeper and change the button style when disabled then overwrite the following CSS classes within your page CSS style file.

.ui-state-disabled,
.ui-widget-content .ui-state-disabled,
.ui-widget-header .ui-state-disabled {
      background-color:aqua;
      color:black;
 }

But remember: those CSS classes (if changed) will change the style for other widgets too.

As an example of the difference -- if you have a task the does something with the UI thread (e.g. a task that represents an animation in a Storyboard) if you Task.WaitAll() then the UI thread is blocked and the UI is never updated. if you use await Task.WhenAll() then the UI thread is not blocked, and the UI will be updated.

I think it's just for your convenience (and the readers of your code)

Your code, and your unit tests should be ideally self documenting which this API helps with,

Think abt what is more clear to read:

AssertTrue(!(a > 3));

or

AssertFalse(a > 3);

When you open your tests after xx months when your tests suddenly fail, it would take you much less time to understand what went wrong in the second case (my opinion). If you disagree, you can always stick with AssertTrue for all cases :)

As another poster said, it's typically preferable to have interfaces define capabilities not types. I would tend not to "implement" something like a "User," and this is why "IUser" often isn't really necessary in the way described here. I often see classes as nouns and interfaces as adjectives:

class Number implements Comparable{...}  
class MyThread implements Runnable{...}
class SessionData implements Serializable{....}

Sometimes an Adjective doesn't make sense, but I'd still generally be using interfaces to model behavior, actions, capabilities, properties, etc,... not types.

Also, If you were really only going to make one User and call it User then what's the point of also having an IUser interface? And if you are going to have a few different types of users that need to implement a common interface, what does appending an "I" to the interface save you in choosing names of the implementations?

I think a more realistic example would be that some types of users need to be able to login to a particular API. We could define a Login interface, and then have a "User" parent class with SuperUser, DefaultUser, AdminUser, AdministrativeContact, etc suclasses, some of which will or won't implement the Login (Loginable?) interface as necessary.

I think this will do:

$('#'+div_id+' .widget-head > span').text("new dialog title");

With nginx you can send both tokens like this (even though it's against the standard):

Authorization: Basic basic-token,Bearer bearer-token

This works as long as the basic token is first - nginx successfully forwards it to the application server.

And then you need to make sure your application can properly extract the Bearer from the above string.

This is really a tricky thing to have a sticky header on your table. I had same requirement but with asp:GridView and then I found it really thought to have sticky header on gridview. There are many solutions available and it took me 3 days trying all the solution but none of them could satisfy.

The main issue that I faced with most of these solutions was the alignment problem. When you try to make the header floating, somehow the alignment of header cells and body cells get off track.

With some solutions, I also got issue of getting header overlapped to first few rows of body, which cause body rows getting hidden behind the floating header.

So now I had to implement my own logic to achieve this, though I also not consider this as perfect solution but this could also be helpful for someone,

Below is the sample table.

<div class="table-holder">
        <table id="MyTable" cellpadding="4" cellspacing="0" border="1px" class="customerTable">
            <thead>
                <tr><th>ID</th><th>First Name</th><th>Last Name</th><th>DOB</th><th>Place</th></tr>
            </thead>
            <tbody>
                <tr><td>1</td><td>Customer1</td><td>LastName</td><td>1-1-1</td><td>SUN</td></tr>
                <tr><td>2</td><td>Customer2</td><td>LastName</td><td>2-2-2</td><td>Earth</td></tr>
                <tr><td>3</td><td>Customer3</td><td>LastName</td><td>3-3-3</td><td>Mars</td></tr>
                <tr><td>4</td><td>Customer4</td><td>LastName</td><td>4-4-4</td><td>Venus</td></tr>
                <tr><td>5</td><td>Customer5</td><td>LastName</td><td>5-5-5</td><td>Saturn</td></tr>
                <tr><td>6</td><td>Customer6</td><td>LastName</td><td>6-6-6</td><td>Jupitor</td></tr>
                <tr><td>7</td><td>Customer7</td><td>LastName</td><td>7-7-7</td><td>Mercury</td></tr>
                <tr><td>8</td><td>Customer8</td><td>LastName</td><td>8-8-8</td><td>Moon</td></tr>
                <tr><td>9</td><td>Customer9</td><td>LastName</td><td>9-9-9</td><td>Uranus</td></tr>
                <tr><td>10</td><td>Customer10</td><td>LastName</td><td>10-10-10</td><td>Neptune</td></tr>
            </tbody>
        </table>
    </div>

Note: The table is wrapped into a DIV with class attribute equal to 'table-holder'.

Below is the JQuery script that I added in my html page header.

<script src="../Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="../Scripts/jquery-ui.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        //create var for table holder
        var originalTableHolder = $(".table-holder");
        // set the table holder's with
        originalTableHolder.width($('table', originalTableHolder).width() + 17);
        // Create a clone of table holder DIV
        var clonedtableHolder = originalTableHolder.clone();

        // Calculate height of all header rows.
        var headerHeight = 0;
        $('thead', originalTableHolder).each(function (index, element) {
            headerHeight = headerHeight + $(element).height();
        });

        // Set the position of cloned table so that cloned table overlapped the original
        clonedtableHolder.css('position', 'relative');
        clonedtableHolder.css('top', headerHeight + 'px');

        // Set the height of cloned header equal to header height only so that body is not visible of cloned header
        clonedtableHolder.height(headerHeight);
        clonedtableHolder.css('overflow', 'hidden');

        // reset the ID attribute of each element in cloned table
        $('*', clonedtableHolder).each(function (index, element) {
            if ($(element).attr('id')) {
                $(element).attr('id', $(element).attr('id') + '_Cloned');
            }
        });

        originalTableHolder.css('border-bottom', '1px solid #aaa');

        // Place the cloned table holder before original one
        originalTableHolder.before(clonedtableHolder);
    });
</script>

and at last below is the CSS class for bit of coloring purpose.

.table-holder
{
    height:200px;
    overflow:auto;
    border-width:0px;    
}

.customerTable thead
{
    background: #4b6c9e;        
    color:White;
}

So the whole idea of this logic is to place the table into a table holder div and create clone of that holder at client side when page loaded. Now hide the body of table inside clone holder and position the remaining header part over to original header.

Same solution also works for asp:gridview, you need to add two more steps to achieve this in gridview,

1. In OnPrerender event of gridview object in your web page, set the table section of header row equal to TableHeader.

   if (this.HeaderRow != null)
   {
       this.HeaderRow.TableSection = TableRowSection.TableHeader;
   }
   

2. And wrap your grid into <div class="table-holder"></div>.

Note: if your header has clickable controls then you may need to add some more jQuery script to pass the events raised in cloned header to original header. This code is already available in jQuery sticky-header plugin create by jmosbech

I needed something similar in a case when i had some fixed Options and i wanted one other option to be editable! In this case i made a hidden input that would overlap the select option and would be editable and used jQuery to make it all work seamlessly.

I am sharing the fiddle with all of you!

HTML

<div id="billdesc">
    <select id="test">
      <option class="non" value="option1">Option1</option>
      <option class="non" value="option2">Option2</option>
      <option class="editable" value="other">Other</option>
    </select>
    <input class="editOption" style="display:none;"></input>
</div>

CSS

body{
    background: blue;
}
#billdesc{
    padding-top: 50px;
}
#test{
    width: 100%;
    height: 30px;
}
option {
    height: 30px;
    line-height: 30px;
}

.editOption{
    width: 90%;
    height: 24px;
    position: relative;
    top: -30px

}

jQuery

var initialText = $('.editable').val();
$('.editOption').val(initialText);

$('#test').change(function(){
var selected = $('option:selected', this).attr('class');
var optionText = $('.editable').text();

if(selected == "editable"){
  $('.editOption').show();


  $('.editOption').keyup(function(){
      var editText = $('.editOption').val();
      $('.editable').val(editText);
      $('.editable').html(editText);
  });

}else{
  $('.editOption').hide();
}
});

Edit : Added some simple touches design wise, so people can clearly see where the input ends!

JS Fiddle : http://jsfiddle.net/69wP6/4/

There is no agreed upon naming convention for HTML and CSS. But you could structure your nomenclature around object design. More specifically what I call Ownership and Relationship.

Ownership

Keywords that describe the object, could be separated by hyphens.

car-new-turned-right

Keywords that describe the object can also fall into four categories (which should be ordered from left to right): Object, Object-Descriptor, Action, and Action-Descriptor.

car - a noun, and an object
new - an adjective, and an object-descriptor that describes the object in more detail
turned - a verb, and an action that belongs to the object
right - an adjective, and an action-descriptor that describes the action in more detail

Note: verbs (actions) should be in past-tense (turned, did, ran, etc).

Relationship

Objects can also have relationships like parent and child. The Action and Action-Descriptor belongs to the parent object, they don't belong to the child object. For relationships between objects you could use an underscore.

car-new-turned-right_wheel-left-turned-left

• car-new-turned-right (follows the ownership rule)
• wheel-left-turned-left (follows the ownership rule)
• car-new-turned-right_wheel-left-turned-left (follows the relationship rule)

Final notes:

• Because CSS is case-insensitive, it's better to write all names in lower-case (or upper-case); avoid camel-case or pascal-case as they can lead to ambiguous names.
• Know when to use a class and when to use an id. It's not just about an id being used once on the web page. Most of the time, you want to use a class and not an id. Web components like (buttons, forms, panels, ...etc) should always use a class. Id's can easily lead to naming conflicts, and should be used sparingly for namespacing your markup. The above concepts of ownership and relationship apply to naming both classes and ids, and will help you avoid naming conflicts.
• If you don't like my CSS naming convention, there are several others as well: Structural naming convention, Presentational naming convention, Semantic naming convention, BEM naming convention, OCSS naming convention, etc.

Unless you have some really compelling reason not to, I suggest ditching the MS JDBC driver.

Instead, use the jtds jdbc driver. Read the README.SSO file in the jtds distribution on how to configure for single-sign-on (native authentication) and where to put the native DLL to ensure it can be loaded by the JVM.

I don't think the Chrome Developer tools pretty print XHR content. See: Viewing HTML response from Ajax call through Chrome Developer tools?

$('.div').html(val) will set the HTML values of all selected elements, $('.div').text(val) will set the text values of all selected elements.

API docs for jQuery.html()

I would guess that they correspond to Node#textContent and Element#innerHTML, respectively. (Gecko DOM references).

You should try this syntax - assuming you want to have @OrderID as a parameter for your stored procedure:

CREATE PROCEDURE dbo.YourStoredProcNameHere
   @OrderID INT
AS
BEGIN
 DECLARE @OrderItemID AS INT
 DECLARE @AppointmentID AS INT
 DECLARE @PurchaseOrderID AS INT
 DECLARE @PurchaseOrderItemID AS INT
 DECLARE @SalesOrderID AS INT
 DECLARE @SalesOrderItemID AS INT

 SELECT @OrderItemID = OrderItemID 
 FROM [OrderItem] 
 WHERE OrderID = @OrderID

 SELECT @AppointmentID = AppoinmentID 
 FROM [Appointment] 
 WHERE OrderID = @OrderID

 SELECT @PurchaseOrderID = PurchaseOrderID 
 FROM [PurchaseOrder] 
 WHERE OrderID = @OrderID

END

OF course, that only works if you're returning exactly one value (not multiple values!)

While C++ (excluding C++11) has enums, the values in them are "leaked" into the global namespace.
If you don't want to have them leaked (and don't NEED to use the enum type), consider the following:

class EnumName {  
   public:   
      static int EnumVal1;  
      (more definitions)  
};  
EnumName::EnumVal1 = {value};  
if ([your value] == EnumName::EnumVal1)  ...

I just found this question and thought it needs a more comprehensive answer:

As of PHP 5.4 there are three methods to accomplish this:

Assembling the response code on your own (PHP >= 4.0)

The header() function has a special use-case that detects a HTTP response line and lets you replace that with a custom one

header("HTTP/1.1 200 OK");

However, this requires special treatment for (Fast)CGI PHP:

$sapi_type = php_sapi_name();
if (substr($sapi_type, 0, 3) == 'cgi')
    header("Status: 404 Not Found");
else
    header("HTTP/1.1 404 Not Found");

Note: According to the HTTP RFC, the reason phrase can be any custom string (that conforms to the standard), but for the sake of client compatibility I do not recommend putting a random string there.

Note: php_sapi_name() requires PHP 4.0.1

3rd argument to header function (PHP >= 4.3)

There are obviously a few problems when using that first variant. The biggest of which I think is that it is partly parsed by PHP or the web server and poorly documented.

Since 4.3, the header function has a 3rd argument that lets you set the response code somewhat comfortably, but using it requires the first argument to be a non-empty string. Here are two options:

header(':', true, 404);
header('X-PHP-Response-Code: 404', true, 404);

I recommend the 2nd one. The first does work on all browsers I have tested, but some minor browsers or web crawlers may have a problem with a header line that only contains a colon. The header field name in the 2nd. variant is of course not standardized in any way and could be modified, I just chose a hopefully descriptive name.

http_response_code function (PHP >= 5.4)

The http_response_code() function was introduced in PHP 5.4, and it made things a lot easier.

http_response_code(404);

That's all.

Compatibility

Here is a function that I have cooked up when I needed compatibility below 5.4 but wanted the functionality of the "new" http_response_code function. I believe PHP 4.3 is more than enough backwards compatibility, but you never know...

// For 4.3.0 <= PHP <= 5.4.0
if (!function_exists('http_response_code'))
{
    function http_response_code($newcode = NULL)
    {
        static $code = 200;
        if($newcode !== NULL)
        {
            header('X-PHP-Response-Code: '.$newcode, true, $newcode);
            if(!headers_sent())
                $code = $newcode;
        }       
        return $code;
    }
}

In C and languages based on the C syntax, the prefix 0x means hexadecimal (base 16).

Thus, 0x400 = 4×(16²) + 0×(16¹) + 0×(16⁰) = 4×((2⁴)²) = 2² × 2⁸ = 2¹⁰ = 1024, or one binary K.

And so 0x6400 = 0x4000 + 0x2400 = 0x19×0x400 = 25K

I think

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

<div>Testing</div>
<div id="result" style="margin:1em 4em; background:rgb(200,200,255); height:500px"></div>
<div style="background:rgb(200,255,200); height:3000px; width:5000px;"></div>

<script>
(function(){
    var link=$("#result");

    var top = link.offset().top; // position from $(document).offset().top
    var bottom = top + link.height(); // position from $(document).offset().top

    var left = link.offset().left; // position from $(document).offset().left
    var right = left + link.width(); // position from $(document).offset().left

    var bottomFromBottom = $(document).height() - bottom;
    // distance from document's bottom
    var rightFromRight = $(document).width() - right;
    // distance from document's right

    var str="";
    str+="top: "+top+"<br>";
    str+="bottom: "+bottom+"<br>";
    str+="left: "+left+"<br>";
    str+="right: "+right+"<br>";
    str+="bottomFromBottom: "+bottomFromBottom+"<br>";
    str+="rightFromRight: "+rightFromRight+"<br>";
    link.html(str);
})();
</script>

The result are

top: 44
bottom: 544
left: 72
right: 1277
bottomFromBottom: 3068
rightFromRight: 3731

in chrome browser of mine.

When the document is scrollable, $(window).height() returns height of browser viewport, not the width of document of which some parts are hiden in scroll. See http://api.jquery.com/height/ .

This is what I ended up doing. I'm sure there is a more efficient way of doing this but this is what i came up with.

Model/User.php

protected $rules = [
    'email_address' => 'sometimes|required|email|unique:users,email_address, {{$id}}',
];

Model/BaseModel.php

public function validate($data, $id = null) {


      $rules = $this->$rules_string;

     //let's loop through and explode the validation rules
     foreach($rules as $keys => $value) {

        $validations = explode('|', $value);

        foreach($validations as $key=>$value) {

            // Seearch for {{$id}} and replace it with $id
            $validations[$key] = str_replace('{{$id}}', $id, $value);

        }
        //Let's create the pipe seperator 
        $implode = implode("|", $validations);
        $rules[$keys] = $implode;

     }
     ....

  }

I pass the $user_id to the validation in the controller

Controller/UserController.php

public function update($id) { 

   .....

    $user = User::find($user_id);

    if($user->validate($formRequest, $user_id)) {
      //validation succcess 
    } 

    ....


}

I tried guava-libraries from google. It has a FluentIterable which I think is close to LINQ. Also see FunctionalExplained.

List<String> parts = new ArrayList<String>();  // add parts to the collection.    
FluentIterable<Integer> partsStartingA = 
    FluentIterable.from(parts).filter(new Predicate<String>() {
        @Override
        public boolean apply(final String input) {
            return input.startsWith("a");
        }
    }).transform(new Function<String, Integer>() {
        @Override
        public Integer apply(final String input) {
            return input.length();
        }
    });

Seems to be an extensive library for Java. Certainly not as succinct as LINQ but looks interesting.

Just wanted to add something to Kamil's answer

After following the steps, I still got an error,

error Could not find device with the name: "....'s Xr"

It Worked !

Hope this will help someone who faced similar issue.

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

My solution:

let isEmpty = (val) => {
    let typeOfVal = typeof val;
    switch(typeOfVal){
        case 'object':
            return (val.length == 0) || !Object.keys(val).length;
            break;
        case 'string':
            let str = val.trim();
            return str == '' || str == undefined;
            break;
        case 'number':
            return val == '';
            break;
        default:
            return val == '' || val == undefined;
    }
};
console.log(isEmpty([1,2,4,5])); // false
console.log(isEmpty({id: 1, name: "Trung",age: 29})); // false
console.log(isEmpty('TrunvNV')); // false
console.log(isEmpty(8)); // false
console.log(isEmpty('')); // true
console.log(isEmpty('   ')); // true
console.log(isEmpty([])); // true
console.log(isEmpty({})); // true

Because the numbers after point is only zero, the best solution is to use the Math.Round(MyNumber)

You write like this-:

xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
           day: '%d %b %Y'    //ex- 01 Jan 2016
        }
}

also check for other datetime format

What you put inside the </dependencies> tag of the root pom will be included by all child modules of the root pom. If all your modules use that dependency, this is the way to go.

However, if only 3 out of 10 of your child modules use some dependency, you do not want this dependency to be included in all your child modules. In that case, you can just put the dependency inside the </dependencyManagement>. This will make sure that any child module that needs the dependency must declare it in their own pom file, but they will use the same version of that dependency as specified in your </dependencyManagement> tag.

You can also use the </dependencyManagement> to modify the version used in transitive dependencies, because the version declared in the upper most pom file is the one that will be used. This can be useful if your project A includes an external project B v1.0 that includes another external project C v1.0. Sometimes it happens that a security breach is found in project C v1.0 which is corrected in v1.1, but the developers of B are slow to update their project to use v1.1 of C. In that case, you can simply declare a dependency on C v1.1 in your project's root pom inside `, and everything will be good (assuming that B v1.0 will still be able to compile with C v1.1).

AngularJS' orderBy filter does just support arrays - no objects. So you have to write an own small filter, which does the sorting for you.

Or change the format of data you handle with (if you have influence on that). An array containing objects is sortable by native orderBy filter.

Here is my orderObjectBy filter for AngularJS:

app.filter('orderObjectBy', function(){
 return function(input, attribute) {
    if (!angular.isObject(input)) return input;

    var array = [];
    for(var objectKey in input) {
        array.push(input[objectKey]);
    }

    array.sort(function(a, b){
        a = parseInt(a[attribute]);
        b = parseInt(b[attribute]);
        return a - b;
    });
    return array;
 }
});

Usage in your view:

<div class="item" ng-repeat="item in items | orderObjectBy:'position'">
    //...
</div>

The object needs in this example a position attribute, but you have the flexibility to use any attribute in objects (containing an integer), just by definition in view.

Example JSON:

{
    "123": {"name": "Test B", "position": "2"},
    "456": {"name": "Test A", "position": "1"}
}

Here is a fiddle which shows you the usage: http://jsfiddle.net/4tkj8/1/

The minium sdk version should be same as of the modules/lib you are using For example: Your module min sdk version is 26 and your app min sdk version is 21 It should be same.

Using JDOM:

    String message = doc.getRootElement().getText();
    System.out.println(message);
} catch (JDOMException e) {

    System.out.println(message);
} catch (SAXException e) {
    // handle SAXException 
} catch (IOException e) {
    // handle IOException

DocumentBuilder db = null;
try {

        String message = doc.getDocumentElement().getTextContent();
        System.out.println(message);
    } catch (SAXException e) {
        // handle SAXException
    } catch (IOException e) {
        // handle IOException
    }
} catch (ParserConfigurationException e1) {
    // handle ParserConfigurationException
}

None of these worked for me.

I was experiencing this issue in only once particular class. What finally worked for me was to delete the offending class and recreate it. Problem solved... mystery not so much!

EDIT: Use this Solution here: https://stackoverflow.com/a/20559175/2033223 Works perfect!

First of, thank for your solution @luizfelipetx

I changed your solution a little bit. This works for me:

public static String getRealPathFromDocumentUri(Context context, Uri uri){
    String filePath = "";

    Pattern p = Pattern.compile("(\\d+)$");
    Matcher m = p.matcher(uri.toString());
    if (!m.find()) {
        Log.e(ImageConverter.class.getSimpleName(), "ID for requested image not found: " + uri.toString());
        return filePath;
    }
    String imgId = m.group();

    String[] column = { MediaStore.Images.Media.DATA };
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ imgId }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();

    return filePath;
}

Note: So we got documents and image, depending, if the image comes from 'recents', 'gallery' or what ever. So I extract the image ID first before looking it up.

The three options that come to mind:

1st) End void loop() with while(1)... or equally as good... while(true)

void loop(){
    //the code you want to run once here, 
    //e.g., If (blah == blah)...etc.

    while(1)        //last line of main loop
}

This option runs your code once and then kicks the Ard into an endless "invisible" loop. Perhaps not the nicest way to go, but as far as outside appearances, it gets the job done.
The Ard will continue to draw current while it spins itself in an endless circle... perhaps one could set up a sort of timer function that puts the Ard to sleep after so many seconds, minutes, etc., of looping... just a thought... there are certainly various sleep libraries out there... see e.g., Monk, Programming Arduino: Next Steps, pgs., 85-100 for further discussion of such.

2nd) Create a "stop main loop" function with a conditional control structure that makes its initial test fail on a second pass.
This often requires declaring a global variable and having the "stop main loop" function toggle the value of the variable upon termination. E.g.,

boolean stop_it = false;         //global variable

void setup(){
    Serial.begin(9600); 
    //blah...
}

boolean stop_main_loop(){        //fancy stop main loop function

    if(stop_it == false){   //which it will be the first time through

        Serial.println("This should print once.");

       //then do some more blah....you can locate all the
       // code you want to run once here....eventually end by 
       //toggling the "stop_it" variable ... 
    }
    stop_it = true; //...like this
    return stop_it;   //then send this newly updated "stop_it" value
                     // outside the function
}

void loop{ 

    stop_it = stop_main_loop();     //and finally catch that updated 
                                    //value and store it in the global stop_it 
                                    //variable, effectively 
                                    //halting the loop  ...
}

Granted, this might not be especially pretty, but it also works.
It kicks the Ard into another endless "invisible" loop, but this time it's a case of repeatedly checking the if(stop_it == false) condition in stop_main_loop() which of course fails to pass every time after the first time through.

3rd) One could once again use a global variable but use a simple if (test == blah){} structure instead of a fancy "stop main loop" function.

boolean start = true;                  //global variable

void setup(){

      Serial.begin(9600);
}

void loop(){

      if(start == true){           //which it will be the first time through



           Serial.println("This should print once.");       

           //the code you want to run once here, 
           //e.g., more If (blah == blah)...etc.

     }

start = false;                //toggle value of global "start" variable
                              //Next time around, the if test is sure to fail.
}

There are certainly other ways to "stop" that pesky endless main loop but these three as well as those already mentioned should get you started.

Had the same problem while trying to run WCF app from Visual Studio. Solved it by running Visual Studio as administrator.

No you would have to create your own solution. Like using the Observer design pattern or something.

If you have no control over the variable or who is using it, I'm afraid you're doomed. EDIT: Or use Skilldrick's solution!

Mike

There are some good answers here already. But it's worthwhile to drive home the difference in parallelism offered:

• success() returns the original promise
• then() returns a new promise

The difference is then() drives sequential operations, since each call returns a new promise.

$http.get(/*...*/).
  then(function seqFunc1(response){/*...*/}).
  then(function seqFunc2(response){/*...*/})

1. $http.get()
2. seqFunc1()
3. seqFunc2()

success() drives parallel operations, since handlers are chained on the same promise.

$http(/*...*/).
  success(function parFunc1(data){/*...*/}).
  success(function parFunc2(data){/*...*/})

1. $http.get()
2. parFunc1(), parFunc2() in parallel

Finally in .NET 4.5, the CLR allows one to hint/suggest¹ method inlining using MethodImplOptions.AggressiveInlining value. It is also available in the Mono's trunk (committed today).

// The full attribute usage is in mscorlib.dll,
// so should not need to include extra references
using System.Runtime.CompilerServices; 

...

[MethodImpl(MethodImplOptions.AggressiveInlining)]
void MyMethod(...)

1. Previously "force" was used here. Since there were a few downvotes, I'll try to clarify the term. As in the comments and the documentation, The method should be inlined if possible. Especially considering Mono (which is open), there are some mono-specific technical limitations considering inlining or more general one (like virtual functions). Overall, yes, this is a hint to compiler, but I guess that is what was asked for.

I know that this is not the C#, but in the framework (VB.NET) there is already such a function

Dim str As String = "UPPERlower"
Dim b As Boolean = InStr(str, "UpperLower")

C# variant:

string myString = "Hello World";
bool contains = Microsoft.VisualBasic.Strings.InStr(myString, "world");

Query string and parameters are different.

You need to use both in single routing url

Please check below example may be useful for you.

app.get('/sample/:id', function(req, res) {

 var id = req.params.id; //or use req.param('id')

  ................

});

Get the link to pass your second segment is your id example: http://localhost:port/sample/123

If you facing problem please use Passing variables as query string using '?' operator

  app.get('/sample', function(req, res) {

     var id = req.query.id; 

      ................

    });

Get link your like this example: http://localhost:port/sample?id=123

Both in a single example

app.get('/sample/:id', function(req, res) {

 var id = req.params.id; //or use req.param('id')
 var id2 = req.query.id; 
  ................

});

Get link example: http://localhost:port/sample/123?id=123

Let me add here that one very minor issue that could generate this type of error is the missing .git extension in the repository URL. Ensure you enter the fully qualified URL ending with .git. I use bitbucket so what I do do is do click 'clone' and the fully qualified URL is automatically generated for me. There is a similar approach with github.

I was getting this same error on my server - PHP 7.0 with the mysqlnd extension already enabled.

Solution was for me (thanks to this page) was to deselect the mysqli extension and select nd_mysqli instead.

NB - You may be able to access the extensions selector in your cPanel. (I access mine via the Select PHP Version option.)

This is simple way to convert files to Base64 and avoid "maximum call stack size exceeded at FileReader.reader.onload" with the file has big size.

document.querySelector('#fileInput').addEventListener('change',   function () {_x000D_
_x000D_
    var reader = new FileReader();_x000D_
    var selectedFile = this.files[0];_x000D_
_x000D_
    reader.onload = function () {_x000D_
        var comma = this.result.indexOf(',');_x000D_
        var base64 = this.result.substr(comma + 1);_x000D_
        console.log(base64);_x000D_
    }_x000D_
    reader.readAsDataURL(selectedFile);_x000D_
}, false);

<input id="fileInput" type="file" />

I have a better way:

http
    .authorizeRequests()
    .antMatchers("/api/v1/signup/**").permitAll()
    .anyRequest().authenticated()

you need to call the function like this

$this->assign()

instead of just assign()

Use this:

$('a[href^="#"]').on('click', function(event) {

    var target = $( $(this).attr('href') );

    if( target.length ) {
        event.preventDefault();
        $('html, body').animate({
            scrollTop: target.offset().top
        }, 500);
    }

});

It is because it's being converted from a binary representation. Just because it has printed all those decimal digits doesn't mean it can represent all decimal values to that precision. Take, for example, this in Python:

>>> 0.14285714285714285
0.14285714285714285
>>> 0.14285714285714286
0.14285714285714285

Notice how I changed the last digit, but it printed out the same number anyway.

A layer in a neural network without a bias is nothing more than the multiplication of an input vector with a matrix. (The output vector might be passed through a sigmoid function for normalisation and for use in multi-layered ANN afterwards but that’s not important.)

This means that you’re using a linear function and thus an input of all zeros will always be mapped to an output of all zeros. This might be a reasonable solution for some systems but in general it is too restrictive.

Using a bias, you’re effectively adding another dimension to your input space, which always takes the value one, so you’re avoiding an input vector of all zeros. You don’t lose any generality by this because your trained weight matrix needs not be surjective, so it still can map to all values previously possible.

2d ANN:

For a ANN mapping two dimensions to one dimension, as in reproducing the AND or the OR (or XOR) functions, you can think of a neuronal network as doing the following:

On the 2d plane mark all positions of input vectors. So, for boolean values, you’d want to mark (-1,-1), (1,1), (-1,1), (1,-1). What your ANN now does is drawing a straight line on the 2d plane, separating the positive output from the negative output values.

Without bias, this straight line has to go through zero, whereas with bias, you’re free to put it anywhere. So, you’ll see that without bias you’re facing a problem with the AND function, since you can’t put both (1,-1) and (-1,1) to the negative side. (They are not allowed to be on the line.) The problem is equal for the OR function. With a bias, however, it’s easy to draw the line.

Note that the XOR function in that situation can’t be solved even with bias.

curl -X PUT -T "/path/to/file" "http://myputserver.com/puturl.tmp"

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

@Bryce, really nice answer.

VB.NET version:

Public Shared Iterator Function FindVisualChildren(Of T As DependencyObject)(depObj As DependencyObject) As IEnumerable(Of T)
    If depObj IsNot Nothing Then
        For i As Integer = 0 To VisualTreeHelper.GetChildrenCount(depObj) - 1
            Dim child As DependencyObject = VisualTreeHelper.GetChild(depObj, i)
            If child IsNot Nothing AndAlso TypeOf child Is T Then
                Yield DirectCast(child, T)
            End If
            For Each childOfChild As T In FindVisualChildren(Of T)(child)
                Yield childOfChild
            Next
        Next
    End If
End Function

Usage (this disables all TextBoxes in a window):

        For Each tb As TextBox In FindVisualChildren(Of TextBox)(Me)
          tb.IsEnabled = False
        Next

From C# 5.0, you can specify the method as

public async Task<bool> doAsyncOperation()
{
    // do work
    return true;
}

bool result = await doAsyncOperation();

Probably the easiest way:

<input type='text' id='abc' value="hel'lo">

It's the '+' operator at the beginning of the line that trips things up (not just that you are using two '+' operators consecutively). The '+' operator can be used at the end of lines, but not at the beginning.

This works:

ggplot(combined.data, aes(x = region, y = expression, fill = species)) +
geom_boxplot() 

The does not:

ggplot(combined.data, aes(x = region, y = expression, fill = species))
+ geom_boxplot() 

*Error in + geom_boxplot():
invalid argument to unary operator*

You also can't use two '+' operators, which in this case you've done. But to fix this, you'll have to selectively remove those at the beginning of lines.

First make sure you have installed Nginx with the HTTP rewrite module. To install this we need to have pcre-library

How to install pcre library

If the above mentioned are done or if you already have them, then just add the below code in your nginx server block

  if ($host !~* ^www\.) {
    rewrite ^(.*)$ http://www.$host$1 permanent;
  }

To remove www from every request you can use

  if ($host = 'www.your_domain.com' ) {
   rewrite  ^/(.*)$  http://your_domain.com/$1  permanent;
  }

so your server block will look like

  server {
            listen       80;
            server_name  test.com;
            if ($host !~* ^www\.) {
                    rewrite ^(.*)$ http://www.$host$1 permanent;
            }
            client_max_body_size   10M;
            client_body_buffer_size   128k;

            root       /home/test/test/public;
            passenger_enabled on;
            rails_env production;

            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                    root   html;
            }
    }

strip colons from the $time, $to and $from strings, convert to int and then use the following condition to check if the time is between from and to. Example is in php, but shouldn't matter.

if(($to < $from && ($time >= $from || $time <= $to)) ||
    ($time >= $from && $time <= $to)) {
    return true;
}

Implemented with swift on Xcode 6.1

self.tableView.tableFooterView = UIView(frame: CGRectZero)
self.tableView.tableFooterView?.hidden = true

The second line of code does not cause any effect on presentation, you can use to check if is hidden or not.

Set PYTHONPATH environment variable in root project directory.

Considering UNIX-like:

export PYTHONPATH=.

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

you can use LocalDate:

Days.daysBetween(new LocalDate(start), new LocalDate(end)).getDays() 

Remember set sendfile off; or cache headers doesn't work. I use this snipped:

location / {

        index index.php index.html index.htm;
        try_files $uri $uri/ =404; #.s. el /index.html para html5Mode de angular

        #.s. kill cache. use in dev
        sendfile off;
        add_header Last-Modified $date_gmt;
        add_header Cache-Control 'no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0';
        if_modified_since off;
        expires off;
        etag off;
        proxy_no_cache 1;
        proxy_cache_bypass 1; 
    }

I was having this issue when testing my Cordova app on android. It just so happens that this android device does not persist its date, and will reset back to its factory date somehow. The API that it calls has a cert that is valid starting this year, while the device date after bootup is in 2017. For now, I have to adb shell and change the date manually.

I know this may not be your specific error, but I once had a leading space in my path and java would work but javac would not.

For what it's worth, I offer the sage advice: "Examine your Path closely".

What you are doing is pass by value not pass by reference. Because you are sending the value of a variable 'p' to the function 'f' (in main as f(p);)

The same program in C with pass by reference will look like,(!!!this program gives 2 errors as pass by reference is not supported in C)

#include <stdio.h>

void f(int &j) {    //j is reference variable to i same as int &j = i
  j++;
}

int main() {
  int i = 20;
  f(i);
  printf("i = %d\n", i);

  return 0;
}

Output:-

3:12: error: expected ';', ',' or ')' before '&' token
             void f(int &j);
                        ^
9:3:  warning: implicit declaration of function 'f'
               f(a);
               ^

$blog is an object, not an array, so you should access it like so:

$blog->id;
$blog->title;
$blog->content;

1. Download script: https://raw.github.com/pypa/pip/master/contrib/get-pip.py
2. Save it on drive somewhere like C:\pip-script\get-pip.py
3. Navigate to that path from command prompt and run " python get-pip.py "

Guide link: http://www.pip-installer.org/en/latest/installing.html#install-pip

Note: Make sure scripts path like this (C:\Python27\Scripts) is added int %PATH% environment variable as well.

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

Here is my summary of this problem: 5 Ways of Calling Java from Python

http://baojie.org/blog/2014/06/16/call-java-from-python/ (cached)

Short answer: Jpype works pretty well and is proven in many projects (such as python-boilerpipe), but Pyjnius is faster and simpler than JPype

I have tried Pyjnius/Jnius, JCC, javabridge, Jpype and Py4j.

Py4j is a bit hard to use, as you need to start a gateway, adding another layer of fragility.

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;

public class GetJsonFromUrl {
    String url = null;

    public GetJsonFromUrl(String url) {
        this.url = url;
    }

    public String GetJsonData() {
        try {
            URL Url = new URL(url);
            HttpURLConnection connection = (HttpURLConnection) Url.openConnection();
            InputStream is = connection.getInputStream();
            BufferedReader br = new BufferedReader(new InputStreamReader(is));
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line);
            }
            line = sb.toString();
            connection.disconnect();
            is.close();
            sb.delete(0, sb.length());
            return line;
        } catch (Exception e) {
            return null;
        }
    }
}

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

Based on the comment we are removing one property from style attribute.

Here this was not affect, but when more property are used within the style it helpful.

$('#msform').css('display', '')

After this we use

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

To call GET,POST,DELETE,PUT All kind of request, i have created one common function

function CallAPI($method, $api, $data) {
    $url = "http://localhost:82/slimdemo/RESTAPI/" . $api;
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

    switch ($method) {

            break;
    }
    curl_close($curl);
    echo $error_status;
    die;
}

Use defaultdict instead:

from collections import defaultdict
data = defaultdict(list)
data[1].append('hello')

This way you don't have to initialize all the keys you want to use to lists beforehand.

What is happening in your example is that you use one (mutable) list:

alist = [1]
data = dict.fromkeys(range(2), alist)
alist.append(2)
print data

would output {0: [1, 2], 1: [1, 2]}.

The basic difference between Web Services and Web APIs

Web Service:

1) It is a SOAP-based service and returns data as XML.

2) It only supports the HTTP protocol.

3) It is not open source but can be used by any client that understands XML.

5) It requires a SOAP protocol to receive and send data over the network, so it is not a light-weight architecture.

Web API:

1) A Web API is an HTTP based service and returns JSON or XML data by default.

2) It supports the HTTP protocol.

3) It can be hosted within an application or IIS.

4) It is open source and it can be used by any client that understands JSON or XML.

5) It has light-weight architecture and good for devices which have limited bandwidth, like mobile devices.

Use MySQL's STR_TO_DATE() function to parse the string that you're attempting to insert:

INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
  (STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))

I don't see why you shouldn't be able to send html content via a post.

if you encounter any issues, you could perhaps use some kind of encoding / decoding - but I don't see that you will.

Faster clearing than Arrays.fill is with this (From Fast Serialization Lib). I just use arrayCopy (is native) to clear the array:

static Object[] EmptyObjArray = new Object[10000];

public static void clear(Object[] arr) {
    final int arrlen = arr.length;
    clear(arr, arrlen);
}

public static void clear(Object[] arr, int arrlen) {
    int count = 0;
    final int length = EmptyObjArray.length;
    while( arrlen - count > length) {
        System.arraycopy(EmptyObjArray,0,arr,count, length);
        count += length;
    }
    System.arraycopy(EmptyObjArray,0,arr,count, arrlen -count);
}

From a purely "make it fit in the div" perspective, add the following to your table class (jsfiddle):

table-layout: fixed;
width: 100%;

Set your column widths as desired; otherwise, the fixed layout algorithm will distribute the table width evenly across your columns.

For quick reference, here are the table layout algorithms, emphasis mine:

• Fixed (source)

  With this (fast) algorithm, the horizontal layout of the table does not depend on the contents of the cells; it only depends on the table's width, the width of the columns, and borders or cell spacing.

• Automatic (source)

  In this algorithm (which generally requires no more than two passes), the table's width is given by the width of its columns [, as determined by content] (and intervening borders).
  
  [...] This algorithm may be inefficient since it requires the user agent to have access to all the content in the table before determining the final layout and may demand more than one pass.

Click through to the source documentation to see the specifics for each algorithm.

numpy.append is pretty different from list.append in python. I know that's thrown off a few programers new to numpy. numpy.append is more like concatenate, it makes a new array and fills it with the values from the old array and the new value(s) to be appended. For example:

import numpy

old = numpy.array([1, 2, 3, 4])
new = numpy.append(old, 5)
print old
# [1, 2, 3, 4]
print new
# [1, 2, 3, 4, 5]
new = numpy.append(new, [6, 7])
print new
# [1, 2, 3, 4, 5, 6, 7]

I think you might be able to achieve your goal by doing something like:

result = numpy.zeros((10,))
result[0:2] = [1, 2]

# Or
result = numpy.zeros((10, 2))
result[0, :] = [1, 2]

Update:

If you need to create a numpy array using loop, and you don't know ahead of time what the final size of the array will be, you can do something like:

import numpy as np

a = np.array([0., 1.])
b = np.array([2., 3.])

temp = []
while True:
    rnd = random.randint(0, 100)
    if rnd > 50:
        temp.append(a)
    else:
        temp.append(b)
    if rnd == 0:
         break

 result = np.array(temp)

In my example result will be an (N, 2) array, where N is the number of times the loop ran, but obviously you can adjust it to your needs.

The error you're seeing has nothing to do with types, it has to do with the shape of the numpy arrays you're trying to concatenate. If you do np.append(a, b) the shapes of a and b need to match. If you append an (2, n) and (n,) you'll get a (3, n) array. Your code is trying to append a (1, 0) to a (2,). Those shapes don't match so you get an error.

private static void GrantAccess(string file)
        {
            bool exists = System.IO.Directory.Exists(file);
            if (!exists)
            {
                DirectoryInfo di = System.IO.Directory.CreateDirectory(file);
                Console.WriteLine("The Folder is created Sucessfully");
            }
            else
            {
                Console.WriteLine("The Folder already exists");
            }
            DirectoryInfo dInfo = new DirectoryInfo(file);
            DirectorySecurity dSecurity = dInfo.GetAccessControl();
            dSecurity.AddAccessRule(new FileSystemAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), FileSystemRights.FullControl, InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.NoPropagateInherit, AccessControlType.Allow));
            dInfo.SetAccessControl(dSecurity);

        }

You could just loop the rows and read the same cell from each row (doesn't this comprise a column?).

In case anyone's wondering why Eclipse still puts a J2SE-1.5 library on the Java Build Path in a Maven project even if a Java version >= 9 is specified by the maven.compiler.release property (as of October 2020, that is Eclipse version 2020-09 including Maven version 3.6.3): Maven by default uses version 3.1 of the Maven compiler plugin, while the release property has been introduced only in version 3.6.

So don't forget to include a current version of the Maven compiler plugin in your pom.xml when using the release property:

<properties>
    <maven.compiler.release>15</maven.compiler.release>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
        </plugin>
    </plugins>
</build>

Or alternatively but possibly less prominent, specify the Java version directly in the plugin configuration:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <release>15</release>
            </configuration>
        </plugin>
    </plugins>
</build>

This picks up Line's comment on the accepted answer which, had I seen it earlier, would have saved me another hour of searching.

Check out ActiveModel::Dirty (available on all models by default). The documentation is really good, but it lets you do things such as:

@user.street1_changed? # => true/false

You need to use the various Bootstrap 4 centering methods...

• Use text-center for inline elements.
• Use justify-content-center for flexbox elements (ie; form-inline)

https://codeply.com/go/Am5LvvjTxC

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

<section id="cover">
    <div id="cover-caption">
        <div id="container" class="container">
            <div class="row">
                <div class="col-sm-10 offset-sm-1 text-center">
                    <h1 class="display-3">Welcome to Bootstrap 4</h1>
                    <div class="info-form">
                        <form action="" class="form-inline justify-content-center">
                            <div class="form-group">
                                <label class="sr-only">Name</label>
                                <input type="text" class="form-control" placeholder="Jane Doe">
                            </div>
                            <div class="form-group">
                                <label class="sr-only">Email</label>
                                <input type="text" class="form-control" placeholder="[email protected]">

                        </form>
                    </div>
                    <br>

I knew that i am too late for this answer, but i hope this will help to other who are facing and who will face.

As you have written h_url is global var like var = h_url; so you can use that variable anywhere in your file.

• h_url=document.getElementById("u").value; Here h_url contain value of your search box text value whatever user has typed.

• document.getElementById("u"); This is the identifier of your form field with some specific ID.

• Your Search Field without id

  <input type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item..." value="text" />

• Alter Search Field with id

  <input id="u" type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item..." value="text" />

• When you click on submit that will try to fetch value from document.getElementById("u").value; which is syntactically right but you haven't define id so that will return null.

• So, Just make sure while you use form fields first define that ID and do other task letter.

I hope this helps you and never get Cannot set property 'value' of null Error.

Here is the proper documentation for the jQueryUI widget. There isn't a built-in parameter for limiting max results, but you can accomplish it easily:

$("#auto").autocomplete({
    source: function(request, response) {
        var results = $.ui.autocomplete.filter(myarray, request.term);

        response(results.slice(0, 10));
    }
});

You can supply a function to the source parameter and then call slice on the filtered array.

Here's a working example: http://jsfiddle.net/andrewwhitaker/vqwBP/

If you want to remove n item from end of array in javascript, you can easily use:

arr.splice(-n, n);

You can get around this by using a traits class:
It requires you set up a specialsed traits class for each actuall class you use.

template<typename SubClass>
class SubClass_traits
{};

template<typename Subclass>
class A {
    public:
        void action(typename SubClass_traits<Subclass>::mytype var)
        {
                (static_cast<Subclass*>(this))->do_action(var);
        }
};


// Definitions for B
class B;   // Forward declare

template<> // Define traits for B. So other classes can use it.
class SubClass_traits<B>
{
    public:
        typedef int mytype;
};

// Define B
class B : public A<B>
{
    // Define mytype in terms of the traits type.
    typedef SubClass_traits<B>::mytype  mytype;
    public:

        B() {}

        void do_action(mytype var) {
                // Do stuff
        }
};

int main(int argc, char** argv)
{
    B myInstance;
    return 0;
} 

I believe it makes sense revisit this question as also pointed out in the comments, the introduction of OpenID Connect may have brought more confusion.

OpenID Connect is an authentication protocol like OpenID 1.0/2.0 but it is actually built on top of OAuth 2.0, so you'll get authorization features along with authentication features. The difference between the two is pretty well explained in detail in this (relatively recent, but important) article: http://oauth.net/articles/authentication/

• com => domain
• something => company name
• something => Main package name

For example: com.paresh.mainpackage

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com. This information i have found at http://download.oracle.com/javase/tutorial/java/package/namingpkgs.html

1. Compile your application with -g, then you'll have debug symbols in the binary file.

2. Use gdb to open the gdb console.

3. Use file and pass it your application's binary file in the console.

4. Use run and pass in any arguments your application needs to start.

5. Do something to cause a Segmentation Fault.

6. Type bt in the gdb console to get a stack trace of the Segmentation Fault.

Assign a int -1 to an unsigned: As -1 does not fit in the range [0...UINT_MAX], multiples of UINT_MAX+1 are added until the answer is in range. Evidently UINT_MAX is pow(2,32)-1 or 429496725 on OP's machine so a has the value of 4294967295.

    unsigned int a = -1;

The "%x", "%u" specifier expects a matching unsigned. Since these do not match, "If a conversion specification is invalid, the behavior is undefined. If any argument is not the correct type for the corresponding conversion specification, the behavior is undefined." C11 §7.21.6.1 9. The printf specifier does not change b.

    printf("%x\n", b);  // UB
    printf("%u\n", b);  // UB

The "%d" specifier expects a matching int. Since these do not match, more UB.

    printf("%d\n", a);  // UB

Given undefined behavior, the conclusions are not supported.

both cases, the bytes are the same (ffffffff).

Even with the same bit pattern, different types may have different values. ffffffff as an unsigned has the value of 4294967295. As an int, depending signed integer encoding, it has the value of -1, -2147483647 or TBD. As a float it may be a NAN.

what is unsigned word for?

unsigned stores a whole number in the range [0 ... UINT_MAX]. It never has a negative value. If code needs a non-negative number, use unsigned. If code needs a counting number that may be +, - or 0, use int.

Update: to avoid a compiler warning about assigning a signed int to unsigned, use the below. This is an unsigned 1u being negated - which is well defined as above. The effect is the same as a -1, but conveys to the compiler direct intentions.

unsigned int a = -1u;

CREATE OR REPLACE PROCEDURE insert_into (
   p_errcode        OUT   NUMBER,
   p_errmesg        OUT   VARCHAR2,

   v_param0   VARCHAR2 (30) := '0.25,2.25,33.689, abc, 99';
   v_param1   VARCHAR2 (30) := '2.65,66.32, abc-def, 21.5';
BEGIN
   FOR i IN (SELECT COLUMN_VALUE
               FROM TABLE (SPLIT (v_param0, ',')))
   LOOP
      INSERT INTO tempo
                  (col1
                  )
           VALUES (i.COLUMN_VALUE
                  );
   END LOOP;

   FOR i IN (SELECT COLUMN_VALUE
               FROM TABLE (SPLIT (v_param1, ',')))
   LOOP
      INSERT INTO tempo

Vector and list aren't conceptually tied to C++. Similar structures can be implemented in C, just the syntax (and error handling) would look different. For example LodePNG implements a dynamic array with functionality very similar to that of std::vector. A sample usage looks like:

uivector v = {};
uivector_push_back(&v, 1);
uivector_push_back(&v, 42);
for(size_t i = 0; i < v.size; ++i)
    printf("%d\n", v.data[i]);
uivector_cleanup(&v);

As can be seen the usage is somewhat verbose and the code needs to be duplicated to support different types.

nothings/stb gives a simpler implementation that works with any types, but compiles only in C:

double *v = 0;
sb_push(v, 1.0);
sb_push(v, 42.0);
for(int i = 0; i < sb_count(v); ++i)
    printf("%g\n", v[i]);
sb_free(v);

A lot of C code, however, resorts to managing the memory directly with realloc:

void* newMem = realloc(oldMem, newSize);
if(!newMem) {
    // handle error
}
oldMem = newMem;

Note that realloc returns null in case of failure, yet the old memory is still valid. In such situation this common (and incorrect) usage leaks memory:

oldMem = realloc(oldMem, newSize);
if(!oldMem) {
    // handle error
}

Compared to std::vector and the C equivalents from above, the simple realloc method does not provide O(1) amortized guarantee, even though realloc may sometimes be more efficient if it happens to avoid moving the memory around.

In some cases, when you check your default encoding (print sys.getdefaultencoding()), it returns that you are using ASCII. If you change to UTF-8, it doesn't work, depending on the content of your variable. I found another way:

import sys
reload(sys)  
sys.setdefaultencoding('Cp1252')

You can use setCustomValidity function when oninvalid event occurs.

Like below:-

<input class="form-control" type="email" required="" 
    placeholder="username" oninvalid="this.setCustomValidity('Please Enter valid email')">
</input>

Update:-

To clear the message once you start entering use oninput="setCustomValidity('') attribute to clear the message.

<input class="form-control" type="email"  required="" placeholder="username"
 oninvalid="this.setCustomValidity('Please Enter valid email')"
 oninput="setCustomValidity('')"></input>

According to the Java docs, it looks like you need to use the MemoryImageSource Class to put your byte array into an object in memory, and then use Component.createImage(ImageProducer) next (passing in your MemoryImageSource, which implements ImageProducer).

Fixed positioning doesn't work on iOS like it does on computers.

Imagine you have a sheet of paper (the webpage) under a magnifying glass(the viewport), if you move the magnifying glass and your eye, you see a different part of the page. This is how iOS works.

Now there is a sheet of clear plastic with a word on it, this sheet of plastic stays stationary no matter what (the position:fixed elements). So when you move the magnifying glass the fixed element appears to move.

Alternatively, instead of moving the magnifying glass, you move the paper (the webpage), keeping the sheet of plastic and magnifying glass still. In this case the word on the sheet of plastic will appear to stay fixed, and the rest of the content will appear to move (because it actually is) This is a traditional desktop browser.

So in iOS the viewport moves, in a traditional browser the webpage moves. In both cases the fixed elements stay still in reality; although on iOS the fixed elements appear to move.

The way to get around this, is to follow the last few paragraphs in this article

(basically disable scrolling altogether, have the content in a separate scrollable div (see the blue box at the top of the linked article), and the fixed element positioned absolutely)

"position:fixed" now works as you'd expect in iOS5.

The most simple solution for me has been to:

1)Select the Range and copy it (ctrl+c)

2)Create a new text file (anywhere, it will be deleted soon), open the text file and then paste in the excel information (ctrl+v)

3)Now that the information in Excel is in the text file, perform a select all in the text file (ctrl+a), and then copy (ctrl+c)

4)Go to the beginning of the original range in step 1, and paste over that old information from the copy in step 3.

DONE! No more false blanks! (you can now delete the temp text file)

you might consider using the Relative and Absolute positining.

`.container {  
position: relative;  
}  
.tag {     
position: absolute;   
}`  

I have tested it there, also if you want it to change its position use this as its margin:

top: 20px;
left: 10px;

It will place it 20 pixels from top and 10 pixels from left; but leave this one if not necessary.

Having the following XML:

<node>Text1<subnode/>text2</node> 

How do I select either the first or the second text node via XPath?

Use:

/node/text()

This selects all text-node children of the top element (named "node") of the XML document.

/node/text()[1]

This selects the first text-node child of the top element (named "node") of the XML document.

/node/text()[2]

This selects the second text-node child of the top element (named "node") of the XML document.

/node/text()[someInteger]

This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:

/node/text()[position() = someInteger]

Old Thread but I found this on my journey to the below answer and figure someone else might need it too.

=IFERROR(ArrayFormula(query(index(Sheet3!A:C&""),"select* Where Col1="""&B1&""" ")), ARRAYFORMULA({"*     *","no cells","match"}));

Here is a simply built text Filter from a 3 column data set (A,B and C) located in "sheet3" into the current sheet and calling a comparison to a cell from the current sheet to filter within Col1(A).

This bit is just to get rid of the #N/A error if the filter turns up no results //ARRAYFORMULA({"* *","no cells","match"}))

Now this answer is for those lost souls that got here with this problem because they force-unmounted the drive but their hard drive is NTFS Formatted. Assuming you have ntfs-3g installed (sudo apt-get install ntfs-3g).

sudo ntfs-3g /dev/hdd /mnt/mount_point -o force

Where hdd is the hard drive in question and the "/mnt/mount_point" directory exists.

NOTES: This fixed the issue on an Ubuntu 18.04 machine using NTFS drives that had their journal files reset through sudo ntfsfix /dev/hdd and unmounted by force using sudo umount -l /mnt/mount_point

Leaving my answer here in case this fix can aid anyone!

This may work:

SELECT Count(tag) AS 'Tag Count'
FROM Table
GROUP BY tag

and

SELECT Count(tag) AS 'Negative Tag Count'
FROM Table
WHERE entryID > 0
GROUP BY tag

function doesNotContainAbcOrDef(x) {
    return (x.match('abc') || x.match('def')) === null;
}

jQuery has a nice function for removing elements from the DOM.

The closest() function is cool because it will "get the first element that matches the selector by testing the element itself and traversing up through its ancestors."

$(this).closest("tr").remove();

Each delete button could run that very succinct code with a function call.

Doing this works for me:

moment(new Date("27/04/2016")).format

If the long string to multiple lines confuses you. Then you may install mz-tools addin which is a freeware and has the utility which splits the line for you.

Download Mz-tools

If your string looks like below

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & "','" & txtContractStartDate.Value & "','" & txtSeatNo.Value & "','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

Simply select the string > right click on VBA IDE > Select MZ-tools > Split Lines

You can do this really easily with ack:

ack -l 'cats' | ack -xl 'dogs'

• -l: return a list of files
• -x: take the files from STDIN (the previous search) and only search those files

And you can just keep piping until you get just the files you want.

I had pip referring by default to pip3, which made me download the libs for python3. On the contrary I launched the shell as python (which opened python 2) and the library wasn't installed there obviously.

Once I matched the names pip3 -> python3, pip -> python (2) all worked.

In onViewHolder set onClickListiner to any view and in side click use this code :

Toast.makeText(Drawer_bar.this, "position" + position, Toast.LENGTH_SHORT).show();

Replace Drawer_Bar with your Activity name.

For e.g. when a user has login.Now lets say the user want to create a forum topic, How will I know that the user is already logged in?

Think about it - there must be some handshake that tells your "Create Forum" API that this current request is from an authenticated user. Since REST APIs are typically stateless, the state must be persisted somewhere. Your client consuming the REST APIs is responsible for maintaining that state. Usually, it is in the form of some token that gets passed around since the time the user was logged in. If the token is good, your request is good.

Check how Amazon AWS does authentications. That's a perfect example of "passing the buck" around from one API to another.

*I thought of adding some practical response to my previous answer. Try Apache Shiro (or any authentication/authorization library). Bottom line, try and avoid custom coding. Once you have integrated your favorite library (I use Apache Shiro, btw) you can then do the following:

1. Create a Login/logout API like: /api/v1/login and api/v1/logout
2. In these Login and Logout APIs, perform the authentication with your user store
3. The outcome is a token (usually, JSESSIONID) that is sent back to the client (web, mobile, whatever)
4. From this point onwards, all subsequent calls made by your client will include this token
5. Let's say your next call is made to an API called /api/v1/findUser
6. The first thing this API code will do is to check for the token ("is this user authenticated?")
7. If the answer comes back as NO, then you throw a HTTP 401 Status back at the client. Let them handle it.
8. If the answer is YES, then proceed to return the requested User

That's all. Hope this helps.

Assume you were:

1. Reading a network file and got disconnected.
2. Reading a local file that was no longer available.
3. Using some stream to read data and some other process closed the stream.
4. Trying to read/write a file, but don't have permission.
5. Trying to write to a file, but disk space was no longer available.

There are many more examples, but these are the most common, in my experience.

The problem I had was related to SOAP version. The asmx service was configured to accept both versions, 1.1 and 1.2, so, I think that when you are consuming the service, the client or the server doesn't know what version resolve.

To fix that, is necessary add:

using (wsWebService yourService = new wsWebService())
{
    yourService.Url = "https://myUrlService.com/wsWebService.asmx?op=someOption";
    yourService.UseDefaultCredentials = true; // this line depends on your authentication type
    yourService.SoapVersion = SoapProtocolVersion.Soap11; // asign the version of SOAP
    var result = yourService.SomeMethod("Parameter");
}

Where wsWebService is the name of the class generated as a reference.

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

I have had a similar issue recently and realised that it's not due to background-size:cover but background-attachment:fixed.

I solved the issue by using a media query for iPhone and setting background-attachment property to scroll.

For my case:

.cover {

To find the distance between 2 points, you need to find the length of the hypotenuse in a right angle triangle with a width and height equal to the vertical and horizontal distance:

Math.hypot(endX - startX, endY - startY)

There is actually, a less heavy-handed way of doing a stream copy. Take note however, that this implies that you can store the entire file in memory. Don't try and use this if you are working with files that go into the hundreds of megabytes or more, without caution.

public static void CopySmallTextStream(Stream input, Stream output)
{
  using (StreamReader reader = new StreamReader(input))
  using (StreamWriter writer = new StreamWriter(output))
  {
    writer.Write(reader.ReadToEnd());
  }
}

NOTE: There may also be some issues concerning binary data and character encodings.

if you want include Id

async getMarkers() {
  const events = await firebase.firestore().collection('events')
  events.get().then((querySnapshot) => {
      const tempDoc = querySnapshot.docs.map((doc) => {
        return { id: doc.id, ...doc.data() }
      })
      console.log(tempDoc)
    })
}

Same way with array

async getMarkers() {
  const events = await firebase.firestore().collection('events')
  events.get().then((querySnapshot) => {
      const tempDoc = []
      querySnapshot.forEach((doc) => {
         tempDoc.push({ id: doc.id, ...doc.data() })
      })
      console.log(tempDoc)
   })
 }

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

Probably I have found myself:

ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
return connectivityManager.getActiveNetworkInfo().isConnectedOrConnecting();

Maven plugin uses a settings file where the configuration can be set. Its path is available in Eclipse at Window|Preferences|Maven|User Settings. If the file doesn't exist, create it and put on something like this:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies>
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>192.168.1.100</host>
      <port>6666</port>
      <username></username>

      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
  </proxies>
  <profiles/>
  <activeProfiles/>
</settings>

After editing the file, it's just a matter of clicking on Update Settings button and it's done. I've just done it and it worked :)

I suspect you haven't authorize your Excel installation to run macro from an automated Excel. It is a security protection by default at installation. To change this:

1. File > Options > Trust Center
2. Click on Trust Center Settings... button
3. Macro Settings > Check Enable all macros

Run:

pip  list

You should get a list of packages (including panda) and their versions, e.g.:

beautifulsoup4 (4.5.1)
cycler (0.10.0)
jdcal (1.3)
matplotlib (1.5.3)
numpy (1.11.1)
openpyxl (2.2.0b1)
pandas (0.18.1)
pip (8.1.2)
pyparsing (2.1.9)
python-dateutil (2.2)
python-nmap (0.6.1)
pytz (2016.6.1)
requests (2.11.1)
setuptools (20.10.1)
six (1.10.0)
SQLAlchemy (1.0.15)
xlrd (1.0.0)

Just for the shake of completing the answer given by eipi10.

I was facing the same problem, without using scale_y_continuous nor coord_cartesian.

The conflict was coming from the x axis, where I defined limits = c(1, 30). It seems such limits do not provide enough space if you want to "dodge" your bars, so R still throws the error

Removed 8 rows containing missing values (geom_bar)

Adjusting the limits of the x axis to limits = c(0, 31) solved the problem.

In conclusion, even if you are not putting limits to your y axis, check out your x axis' behavior to ensure you have enough space

make your class public access modifier,

just add public keyword infront of your class name

 namespace Test
{
  public  class Delivery
    {
        private string name;
        private string address;
        private DateTime arrivalTime;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }

        public string Address
        {
            get { return address; }
            set { address = value; }
        }

        public DateTime ArrivlaTime
        {
            get { return arrivalTime; }
            set { arrivalTime = value; }
        }

        public string ToString()
        {
            { return name + address + arrivalTime.ToString(); }
        }
    }
}

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

For those coming here and are using Java config you can set the Bean to lazy-init using annotations like this:

In the configuration class:

@Configuration
// @Lazy - For all Beans to load lazily
public class AppConf {

    @Bean
    @Lazy
    public Demo demo() {
        return new Demo();
    }
}

For component scanning and auto-wiring:

@Component
@Lazy
public class Demo {
    ....
    ....
}

@Component
public class B {

    @Autowired
    @Lazy // If this is not here, Demo will still get eagerly instantiated to satisfy this request.
    private Demo demo;

    .......
 }

You can use the regex

(\s)\1

and

replace it with $1.

Java code:

str = str.replaceAll("(\\s)\\1","$1");

If the input is "foo\t\tbar " you'll get "foo\tbar " as output
But if the input is "foo\t bar" it will remain unchanged because it does not have any consecutive whitespace characters.

If you treat all the whitespace characters(space, vertical tab, horizontal tab, carriage return, form feed, new line) as space then you can use the following regex to replace any number of consecutive white space with a single space:

str = str.replaceAll("\\s+"," ");

But if you want to replace two consecutive white space with a single space you should do:

str = str.replaceAll("\\s{2}"," ");

List

dict = {'Neetu':22,'Shiny':21,'Poonam':23}
print sorted(dict.items())
sv = sorted(dict.values())
print sv

Dictionary

d = []
l = len(sv)
while l != 0 :
    d.append(sv[l - 1])
    l = l - 1
print d`
