Bootstrap Version 3.x

As always, read Bootstrap's great documentation:

3.x Docs: https://getbootstrap.com/docs/3.3/css/#grid-nesting

Make sure the parent level row is inside of a .container element. Whenever you'd like to nest rows, just open up a new .row inside of your column.

Here's a simple layout to work from:

<div class="container">
    <div class="row">
        <div class="col-xs-6">
            <div class="big-box">image</div>
        </div>
        <div class="col-xs-6">
            <div class="row">
                <div class="col-xs-6"><div class="mini-box">1</div></div>
                <div class="col-xs-6"><div class="mini-box">2</div></div>
                <div class="col-xs-6"><div class="mini-box">3</div></div>
                <div class="col-xs-6"><div class="mini-box">4</div></div>
            </div>
        </div>
    </div>
</div>

Bootstrap Version 4.0

4.0 Docs: http://getbootstrap.com/docs/4.0/layout/grid/#nesting

Here's an updated version for 4.0, but you should really read the entire docs section on the grid so you understand how to leverage this powerful feature

<div class="container">
  <div class="row">
    <div class="col big-box">
      image
    </div>

    <div class="col">
      <div class="row">
        <div class="col mini-box">1</div>
        <div class="col mini-box">2</div>
      </div>
      <div class="row">
        <div class="col mini-box">3</div>
        <div class="col mini-box">4</div>
      </div>
    </div>

  </div>
</div>

Which will look like this (with a little bit of added styling):

$(document).on('keyup','#search_product',function(){
    $( "#search_product" ).autocomplete({
      source:function(request,response){
                  $.post("<?= base_url('ecommerce/autocomplete') ?>",{'name':$( "#search_product" ).val()}).done(function(data, status){

                    response(JSON.parse(data));
        });
      }
    });
});

PHP code :

public function autocomplete(){
    $name=$_POST['name'];
    $result=$this->db->select('product_name,sku_code')->like('product_name',$name)->get('product_list')->result_array();
    $names=array();
    foreach($result as $row){
        $names[]=$row['product_name'];
    }
    echo json_encode($names);
}

FSPL depends on two parameters: First is the frequency of radio signals;Second is the wireless transmission distance. The following formula can reflect the relationship between them.

FSPL (dB) = 20log10(d) + 20log10(f) + K

d = distance
f = frequency
K= constant that depends on the units used for d and f
If d is measured in kilometers, f in MHz, the formula is:

FSPL (dB) = 20log10(d)+ 20log10(f) + 32.44

From the Fade Margin equation, Free Space Path Loss can be computed with the following equation.

Free Space Path Loss=Tx Power-Tx Cable Loss+Tx Antenna Gain+Rx Antenna Gain - Rx Cable Loss - Rx Sensitivity - Fade Margin

With the above two Free Space Path Loss equations, we can find out the Distance in km.

Distance (km) = 10(Free Space Path Loss – 32.44 – 20log10(f))/20

The Fresnel Zone is the area around the visual line-of-sight that radio waves spread out into after they leave the antenna. You want a clear line of sight to maintain strength, especially for 2.4GHz wireless systems. This is because 2.4GHz waves are absorbed by water, like the water found in trees. The rule of thumb is that 60% of Fresnel Zone must be clear of obstacles. Typically, 20% Fresnel Zone blockage introduces little signal loss to the link. Beyond 40% blockage the signal loss will become significant.

FSPLr=17.32*v(d/4f)

d = distance [km]
f = frequency [GHz]
r = radius [m]

Checkout the -maxdepth flag of find

find . -maxdepth 1 -type d -exec ls -ld "{}" \;

Here I used 1 as max level depth, -type d means find only directories, which then ls -ld lists contents of, in long format.

This might be off-topic. But for the wget in for loop, you can certainly do

curl -O http://example.com/search/link[1-600]

If you have Bluetooth, Use twedge on windows and getblue app on android, they also have a few videos of it. It's made by TEC-IT. I've got it to work by setting the interface option to bluetooth server in TWedge and setting the output setting in getblue to Bluetooth client and selecting my computer from the Bluetooth devices list. Make sure your computer and phone is paired. Also to get the barcode as input set the action setting in TWedge to Keyboard Wedge. This will allow for you to first click the input text box on said form, then scan said product with your phone and wait a sec for the barcode number to be put into the text box. Using this method requires no php that doesn't already exist in your current form processing, just process the text box as usual and viola your phone scans bar codes, sends them to your pc via Bluetooth wirelessly, your computer inserts the barcode into whatever text field is selected in any application or website. Hope this helps.

This code works for me:

#!/bin/sh

argc=$#
echo $argc
if [ $argc -eq 0 -o $argc -eq 1 ]; then
  echo "foo"
else
  echo "bar"
fi

I don't think sh supports "==". Use "=" to compare strings and -eq to compare ints.

man test

for more details.

BULK INSERT dbo.temp

Here's a solution that doesn't use JS at all. It uses checkboxes instead.

You can hide the checkbox by adding this to your CSS:

.container input{
    display: none;
}

And then add some styling to make it look like a button.

Here's the source code that I modded.

There are at least two possible situations:

1. you are deleting the same entity twice
2. you are deleting something that wasn't allocated

For the first one I strongly suggest NULL-ing all deleted pointers.

You have three options:

1. overload new and delete and track the allocations
2. yes, use gdb -- then you'll get a backtrace from your crash, and that'll probably be very helpful
3. as suggested -- use Valgrind -- it isn't easy to get into, but it will save you time thousandfold in the future...

I do it like this:

(Shortened the code a bit)

public struct Age
{
    public readonly int Years;
    public readonly int Months;
    public readonly int Days;

}

public Age( int y, int m, int d ) : this()
{
    Years = y;
    Months = m;
    Days = d;
}

public static Age CalculateAge ( DateTime birthDate, DateTime anotherDate )
{
    if( startDate.Date > endDate.Date )
        {
            throw new ArgumentException ("startDate cannot be higher then endDate", "startDate");
        }

        int years = endDate.Year - startDate.Year;
        int months = 0;
        int days = 0;

        // Check if the last year, was a full year.
        if( endDate < startDate.AddYears (years) && years != 0 )
        {
            years--;
        }

        // Calculate the number of months.
        startDate = startDate.AddYears (years);

        if( startDate.Year == endDate.Year )
        {
            months = endDate.Month - startDate.Month;
        }
        else
        {
            months = ( 12 - startDate.Month ) + endDate.Month;
        }

        // Check if last month was a complete month.
        if( endDate < startDate.AddMonths (months) && months != 0 )
        {
            months--;
        }

        // Calculate the number of days.
        startDate = startDate.AddMonths (months);

        days = ( endDate - startDate ).Days;

        return new Age (years, months, days);
}

// Implement Equals, GetHashCode, etc... as well
// Overload equality and other operators, etc...

}

//declare the total variable
int total = 0;
//loop through the datagrid and sum the column 
for(int i=0;i<datagridview1.Rows.Count;i++)
{
    total +=int.Parse(datagridview1.Rows[i].Cells["CELL NAME OR INDEX"].Value.ToString());

}
string tota

I made a function which handles arrays as well as single GET or POST values

function subVal($varName, $default=NULL,$isArray=FALSE ){ // $isArray toggles between (multi)array or single mode

    $retVal = "";
    $retArray = array();

    if($isArray) {
        if(isset($_POST[$varName])) {
            foreach ( $_POST[$varName] as $var ) {  // multidimensional POST array elements
                $retArray[]=$var;
            }
        }
        $retVal=$retArray;
    }

    elseif (isset($_POST[$varName]) )  {  // simple POST array element
        $retVal = $_POST[$varName];
    }

    else {
        if (isset($_GET[$varName]) ) {
            $retVal = $_GET[$varName];    // simple GET array element
        }
        else {
            $retVal = $default;
        }
    }

    return $retVal;

}

Examples:

$curr_topdiameter = subVal("topdiameter","",TRUE)[3];
$user_name = subVal("user_name","");

I had to do something similar to Sean and ilalex's answer.
But I had too many options to explicitly define the sort order for and only needed to float certain entries to the front of the list ... in the specified (non-natural) order.
Hopefully this is helpful to someone else.

public class CarComparator implements Comparator<Car> {

    //sort these items in this order to the front of the list 
    private static List<String> ORDER = Arrays.asList("dd", "aa", "cc", "bb");

    public int compare(final Car o1, final Car o2) {
        int result = 0;
        int o1Index = ORDER.indexOf(o1.getName());
        int o2Index = ORDER.indexOf(o2.getName());
        //if neither are found in the order list, then do natural sort
        //if only one is found in the order list, float it above the other
        //if both are found in the order list, then do the index compare
        if (o1Index < 0 && o2Index < 0) result = o1.getName().compareTo(o2.getName());
        else if (o1Index < 0) result = 1;
        else if (o2Index < 0) result = -1;
        else result = o1Index - o2Index;
        return result;
    }

//Testing output: dd,aa,aa,cc,bb,bb,bb,a,aaa,ac,ac,ba,bd,ca,cb,cb,cd,da,db,dc,zz
}

When you start SSMS, it allows you to choose a Server Type and Server Name. In the server type dropdown, choose "Integration Services" and connect to the server.

Then you'll be able to see what packages are in the db.

I had the same issue. I wanted icons to appear by pressing the button but without any movement and sliding the enviroment, just like bulb: on and off, appeared and dissapeared, so I needed to make an empty div with fixed sizes.

width: 13px;
min-width: 13px;

did the trick for me

I solved the problem updating all packages from Android SDK Manager and also, I had to install Extras -> Android Support Repository.

You can proxyfy references to your object with, for example, dictionary singleton. You may store not object, but its ID or hash and access it trought the dictionary. Then when you need to remove the object you set value for its key to null.

You should look at RAND_MAX for your particular compiler/environment. I think you would see these results if rand() is producing a random 16-bit number. (you seem to be assuming it will be a 32-bit number).

I can't promise this is the answer, but please post your value of RAND_MAX, and a little more detail on your environment.

The accepted answer is correct but it doesn't tell you how to use it. This is how you use indexOf and substring functions together.

String filename = "abc.def.ghi";     // full file name
int iend = filename.indexOf("."); //this finds the first occurrence of "." 
//in string thus giving you the index of where it is in the string

// Now iend can be -1, if lets say the string had no "." at all in it i.e. no "." is found. 
//So check and account for it.

String subString;
if (iend != -1) 
{
    subString= filename.substring(0 , iend); //this will give abc
}

Yes you can; it works on Android too:

tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:

* tel:2125551212
* tel: (212) 555 1212

The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:

<a href="tel:2125551212">2125551212</a>

on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.

Have a look to RFC3966

• SQL is a query language to operate on sets.

  It is more or less standardized, and used by almost all relational database management systems: SQL Server, Oracle, MySQL, PostgreSQL, DB2, Informix, etc.

• PL/SQL is a proprietary procedural language used by Oracle

• PL/pgSQL is a procedural language used by PostgreSQL

• TSQL is a proprietary procedural language used by Microsoft in SQL Server.

Procedural languages are designed to extend SQL's abilities while being able to integrate well with SQL. Several features such as local variables and string/data processing are added. These features make the language Turing-complete.

They are also used to write stored procedures: pieces of code residing on the server to manage complex business rules that are hard or impossible to manage with pure set-based operations.

I would go with the traditional find & xargs way:

find ~/Linux/Old -maxdepth 1 -mindepth 1 -not -name Tux.png -print0 | 
    xargs -0 mv -t ~/Linux/New

-maxdepth 1 makes it not search recursively. If you only care about files, you can say -type f. -mindepth 1 makes it not include the ~/Linux/Old path itself into the result. Works with any filenames, including with those that contain embedded newlines.

One comment notes that the mv -t option is a probably GNU extension. For systems that don't have it

find ~/Linux/Old -maxdepth 1 -mindepth 1 -not -name Tux.png \
    -exec mv '{}' ~/Linux/New \;

Wait, are you really needing to render it using javascript?

Be aware that in HTML5 there is srcdoc, which can do that for you! (The drawback is that IE/EDGE does not support it yet https://caniuse.com/#feat=iframe-srcdoc)

See here [srcdoc]: https://www.w3schools.com/tags/att_iframe_srcdoc.asp

Another thing to note is that if you want to avoid the interference of the js code inside and outside you should consider using the sandbox mode.

See here [sandbox]: https://www.w3schools.com/tags/att_iframe_sandbox.asp

can try this

select (CONVERT(VARCHAR(10),GETDATE()+360,110)) as Date_Result

Since jQuery.get is just a shorthand for jQuery.ajax, another way would be to use the latter one's context option, as stated in the documentation:

The this reference within all callbacks is the object in the context option passed to $.ajax in the settings; if context is not specified, this is a reference to the Ajax settings themselves.

So you would use

$.ajax('http://www.example.org', {
  dataType: 'xml',
  data: {'a':1,'b':2,'c':3},
  context: {
    url: 'http://www.example.org'
  }
}).done(function(xml) {alert(this.url});

Thanks a lot for the first answer.

As for me, I had just one problem with it. When inflating my view, i had a bug : java.lang.NoSuchMethodException : MyView(Context, Attributes)

I resolved it by creating a new constructor :

public MyView(Context context, AttributeSet attrs) {
     super(context, attrs);
     // some code
}

Hope this will help !

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

div1 {
    float: right;
} 
div2 {
    float: left;
}

This will work OK as long as you set clear: both for the element that separates this two column block.

For mini pies, lines and bars, Peity is brilliant, simple, tiny, fast, uses really elegant markup.

I'm not sure of it's relationship with Flot (given its name), but Flotr2 is pretty good, certainly does better pies than Flot.

Bluff produces nice-looking line graphs, but I had a bit of trouble with its pies.

Not what I was after, but another commercial product (much like Highcharts) is TeeChart.

You can't do this. A File is just an abstract way to refer to a file in the file system. It doesn't contain any of the file contents itself.

If you're trying to create an in-memory file that can be referred to using a File object, you aren't going to be able to do that, either, as explained in this thread, this thread, and many other places..

git fetch && git checkout branch-name

import json

# some JSON:
json_str =  '{ "name":"Sarah", "age":25, "city":"Chicago"}'

# parse json_str:
json = json.loads(json_str)

# get tags from json   
tags = []
for tag in json:
    tags.append(tag)
  

# print each tag name e your content
for i in range(len(tags)):
    print(tags[i] + ': ' + str(json[tags[i]]))

I was getting the same exact error as well. Here is the fix. When you are specifying where to write to, Android will automatically resolve your path into either /data/ or /mnt/sdcard/. Let me explain.

If you execute the following statement:

File resolveMe = new File("/data/myPackage/files/media/qmhUZU.jpg");
resolveMe.createNewFile();

It will resolve the path to the root /data/ somewhere higher up in Android.

I figured this out, because after I executed the following code, it was placed automatically in the root /mnt/ without me translating anything on my own.

File resolveMeSDCard = new File("/sdcard/myPackage/files/media/qmhUZU.jpg");
resolveMeSDCard.createNewFile();

A quick fix would be to change your following code:

File f = new File(getLocalPath().replace("/data/data/", "/"));

Hope this helps

Second Approach

Adding a new Form for handling Cancel button click. Now, on Cancel button click we will post the second form and will redirect to the home page.

Third Approach: Client Script

<button name="ClientCancel" type="button" 
    onclick=" document.location.href = $('#cancelUrl').attr('href');">Cancel (Client Side)
</button>
<a id="cancelUrl" href="@Html.AttributeEncode(Url.Action("Index", "Home"))"

Breakpoints and especially conditional breakpoints are your friends.

Also you can write small assert like function which will check values and throw exceptions if needed in debug version of site (some variable is set to true or url has some parameter)

To work around the RETURN/GO issue you could put RAISERROR ('Oi! Stop!', 20, 1) WITH LOG at the top.

This will close the client connection as per RAISERROR on MSDN.

The very big downside is you have to be sysadmin to use severity 20.

Edit:

A simple demonstration to counter Jersey Dude's comment...

RAISERROR ('Oi! Stop!', 20, 1)  WITH LOG
SELECT 'Will not run'
GO
SELECT 'Will not run'
GO
SELECT 'Will not run'

The syntax of the class creation statement:

class <ClassName>(superclass):
    #code follows

In the absence of any other superclasses that you specifically want to inherit from, the superclass should always be object, which is the root of all classes in Python.

object is technically the root of "new-style" classes in Python. But the new-style classes today are as good as being the only style of classes.

But, if you don't explicitly use the word object when creating classes, then as others mentioned, Python 3.x implicitly inherits from the object superclass. But I guess explicit is always better than implicit (hell)

Try the following to support basic html tags including ul ol li tags. Create a Tag handler as shown below

import org.xml.sax.XMLReader;

import android.app.Activity;
import android.os.Bundle;
import android.text.Editable;
import android.text.Html;
import android.text.Html.TagHandler;
import android.util.Log;

public class MyTagHandler implements TagHandler {
    boolean first= true;
    String parent=null;
    int index=1;
    @Override
    public void handleTag(boolean opening, String tag, Editable output,
                          XMLReader xmlReader) {

        if(tag.equals("ul")) parent="ul";
        else if(tag.equals("ol")) parent="ol";
        if(tag.equals("li")){
            if(parent.equals("ul")){
                if(first){
                    output.append("\n\t•");
                    first= false;
                }else{
                    first = true;
                }
            }
            else{
                if(first){
                    output.append("\n\t"+index+". ");
                    first= false;
                    index++;
                }else{
                    first = true;
                }
            }
        }
    }
}

Set the text on Activity as shown below

@SuppressWarnings("deprecation")
    public void init(){
        try {
            TextView help = (TextView) findViewById(R.id.help);
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
                help.setText(Html.fromHtml(getString(R.string.help_html),Html.FROM_HTML_MODE_LEGACY, null, new MyTagHandler()));
            } else {
                help.setText(Html.fromHtml(getString(R.string.help_html), null, new MyTagHandler()));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

And html text on resource string files as

<![CDATA[ ...raw html data ...]] >

new Date().getTime();

For more information, see @James McMahon's answer.

It is going to write the value of your property model.Destination

This is by design. You'll want to populate your Destination property with the value you want in your controller before returning your view.

The easiest way for me is doing this:

import datetime
from unittest.mock import Mock, patch

def test():
    datetime_mock = Mock(wraps=datetime.datetime)
    datetime_mock.now.return_value = datetime.datetime(1999, 1, 1)
    with patch('datetime.datetime', new=datetime_mock):
        assert datetime.datetime.now() == datetime.datetime(1999, 1, 1)

CAUTION for this solution: all functionality from datetime module from the target_module will stop working.

DateTime.Now.ToString("M/d/yyyy");

s = "BINGO"
print(" ".join(s))

Should do it.

Incase you're using pandas and your read_excel reads in Date formatted as Excel numbers improperly and need to recover the real dates behind...

The lambda function applied on the column uses xlrd to recover the date back

import xlrd
df['possible_intdate'] = df['possible_intdate'].apply(lambda s: xlrd.xldate.xldate_as_datetime(s, 0))


>> df['possible_intdate']

My answer is too late, but it can help others.

I had the same problem, even when I used a form tag.

I solved it by declaring Meta Charset in the header of the page:

<meta charset = "UTF-8" />

C/C++ standard library <stdlib.h> contains qsort function.

This is not the best quick sort implementation in the world but it fast enough and VERY EASY to be used... the formal syntax of qsort is:

qsort(<arrayname>,<size>,sizeof(<elementsize>),compare_function);

The only thing that you need to implement is the compare_function, which takes in two arguments of type "const void", which can be cast to appropriate data structure, and then return one of these three values:

• negative, if a should be before b
• 0, if a equal to b
• positive, if a should be after b

1. Comparing a list of integers:

simply cast a and b to integers if x < y,x-y is negative, x == y, x-y = 0, x > y, x-y is positive x-y is a shortcut way to do it :) reverse *x - *y to *y - *x for sorting in decreasing/reverse order

int compare_function(const void *a,const void *b) {
int *x = (int *) a;
int *y = (int *) b;
return *x - *y;
}

2. Comparing a list of strings:

For comparing string, you need strcmp function inside <string.h> lib. strcmp will by default return -ve,0,ve appropriately... to sort in reverse order, just reverse the sign returned by strcmp

#include <string.h>
int compare_function(const void *a,const void *b) {
return (strcmp((char *)a,(char *)b));
}

3. Comparing floating point numbers:

int compare_function(const void *a,const void *b) {
double *x = (double *) a;
double *y = (double *) b;
// return *x - *y; // this is WRONG...
if (*x < *y) return -1;
else if (*x > *y) return 1; return 0;
}

4. Comparing records based on a key:

Sometimes you need to sort a more complex stuffs, such as record. Here is the simplest way to do it using qsort library.

typedef struct {
int key;
double value;
} the_record;

int compare_function(const void *a,const void *b) {
the_record *x = (the_record *) a;
the_record *y = (the_record *) b;
return x->key - y->key;
}

This code for those who are experiencing the same problem trying to accessing the camera could be written with a safety check.

if ret is True:
   gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
else:
   continue

OR in case you want to close the camera/ discontinue if there will be some problem with the frame itself

if ret is True:
   gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
else:
   break

For reference https://github.com/HackerShackOfficial/AI-Smart-Mirror/issues/36

No REAL easy way to do this. Lots of ideas out there, though.

Best one I've found:

SELECT table_name, LEFT(column_names , LEN(column_names )-1) AS column_names
FROM information_schema.columns AS extern
CROSS APPLY
(
    SELECT column_name + ','
    FROM information_schema.columns AS intern
    WHERE extern.table_name = intern.table_name
    FOR XML PATH('')
) pre_trimmed (column_names)
GROUP BY table_name, column_names;

Or a version that works correctly if the data might contain characters such as <

WITH extern
     AS (SELECT DISTINCT table_name
         FROM   INFORMATION_SCHEMA.COLUMNS)
SELECT table_name,
       LEFT(y.column_names, LEN(y.column_names) - 1) AS column_names
FROM   extern
       CROSS APPLY (SELECT column_name + ','
                    FROM   INFORMATION_SCHEMA.COLUMNS AS intern
                    WHERE  extern.table_name = intern.table_name
                    FOR XML PATH(''), TYPE) x (column_names)
       CROSS APPLY (SELECT x.column_names.value('.', 'NVARCHAR(MAX)')) y(column_names) 

Or just...

var response = (function() {
    var a;
    // calculate a
    return a;
})();  

In this case, the response variable receives the return value of the function. The function executes immediately.

You can use this construct if you want to populate a variable with a value that needs to be calculated. Note that all calculation happens inside the anonymous function, so you don't pollute the global namespace.

I think this solution uses less code and is easy to understand even for newbie.

For string field in struct, you can use pointer and reassigning the string to that pointer will be straightforward and simpler.

Define definition of struct:

typedef struct {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} Patient;

Initialize variable with type of that struct:

Patient patient;
patient.number = 12345;
patient.address = "123/123 some road Rd.";
patient.birthdate = "2020/12/12";
patient.gender = "M";

It is that simple. Hope this answer helps many developers.

SQL: show full processlist;

This is what the MySQL Workbench does.

I've created a simple example tutorial. You can read this and use in your application.

http://ribinsandroidhelper.blogspot.in/2013/03/qr-code-reading-on-your-application.html

Through this link you can download the qrcode library project and import into your workspace and add library to your project

and copy this code to your activity

 Intent intent = new Intent("com.google.zxing.client.android.SCAN");
 startActivityForResult(intent, 0);

 public void onActivityResult(int requestCode, int resultCode, Intent intent) {
     if (requestCode == 0) {
         if (resultCode == RESULT_OK) {
             String contents = intent.getStringExtra("SCAN_RESULT");
             String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
             Toast.makeText(this, contents,Toast.LENGTH_LONG).show();
             // Handle successful scan
         } else if (resultCode == RESULT_CANCELED) {
             //Handle cancel
         }
     }
}

I found this worked best for me.

In AndroidManifest.xml <activity> element add android:windowSoftInputMode="stateHidden"

This always hides the keyboard when entering the activity.

You can achieve what you want without the instanceof keyword as you can write custom type guards now:

interface A{
    member:string;
}

function instanceOfA(object: any): object is A {
    return 'member' in object;
}

var a:any={member:"foobar"};

if (instanceOfA(a)) {
    alert(a.member);
}

Lots of Members

If you need to check a lot of members to determine whether an object matches your type, you could instead add a discriminator. The below is the most basic example, and requires you to manage your own discriminators... you'd need to get deeper into the patterns to ensure you avoid duplicate discriminators.

interface A{
    discriminator: 'I-AM-A';
    member:string;
}

function instanceOfA(object: any): object is A {
    return object.discriminator === 'I-AM-A';
}

var a:any = {discriminator: 'I-AM-A', member:"foobar"};

if (instanceOfA(a)) {
    alert(a.member);
}

Microsoft has a tool called JLCA: Java Language Conversion Assistant. I can't tell if it is better though, as I have never compared the two.

array(A) or array(t(A)) will give you a 1-d array.

If the list is sorted (as happens to be in the example) a binary search on index certainly works.

    public static Dog Find(List<Dog> AllDogs, string Id)
    {
        int p = 0;
        int n = AllDogs.Count;
        while (true)
        {
            int m = (n + p) / 2;
            Dog d = AllDogs[m];
            int r = string.Compare(Id, d.Id);
            if (r == 0)
                return d;
            if (m == p)
                return null;
            if (r < 0)
                n = m;
            if (r > 0)
                p = m;
        }
    }

Not sure what the LINQ version of this would be.

Looping the pointer to gain better performance:

#include <ctype.h>

char* toLower(char* s) {
  for(char *p=s; *p; p++) *p=tolower(*p);
  return s;
}
char* toUpper(char* s) {
  for(char *p=s; *p; p++) *p=toupper(*p);
  return s;
}

sudoPassword = 'mypass'
command = 'mount -t vboxsf myfolder /home/myuser/myfolder'
p = os.system('echo %s|sudo -S %s' % (sudoPassword, command))

Try this and let me know if it works. :-)

And this one:

os.popen("sudo -S %s"%(command), 'w').write('mypass')

tl;dr

Instant and LocalDateTime are two entirely different animals: One represents a moment, the other does not.

• Instant represents a moment, a specific point in the timeline.
• LocalDateTime represents a date and a time-of-day. But lacking a time zone or offset-from-UTC, this class cannot represent a moment. It represents potential moments along a range of about 26 to 27 hours, the range of all time zones around the globe. A LocalDateTime value is inherently ambiguous.

Incorrect Presumption

LocalDateTime is rather date/clock representation including time-zones for humans.

Your statement is incorrect: A LocalDateTime has no time zone. Having no time zone is the entire point of that class.

To quote that class’ doc:

This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

So Local… means “not zoned, no offset”.

Instant

An Instant is a moment on the timeline in UTC, a count of nanoseconds since the epoch of the first moment of 1970 UTC (basically, see class doc for nitty-gritty details). Since most of your business logic, data storage, and data exchange should be in UTC, this is a handy class to be used often.

Instant instant = Instant.now() ;  // Capture the current moment in UTC.

OffsetDateTime

The class OffsetDateTime class represents a moment as a date and time with a context of some number of hours-minutes-seconds ahead of, or behind, UTC. The amount of offset, the number of hours-minutes-seconds, is represented by the ZoneOffset class.

If the number of hours-minutes-seconds is zero, an OffsetDateTime represents a moment in UTC the same as an Instant.

ZoneOffset

The ZoneOffset class represents an offset-from-UTC, a number of hours-minutes-seconds ahead of UTC or behind UTC.

A ZoneOffset is merely a number of hours-minutes-seconds, nothing more. A zone is much more, having a name and a history of changes to offset. So using a zone is always preferable to using a mere offset.

ZoneId

A time zone is represented by the ZoneId class.

A new day dawns earlier in Paris than in Montréal, for example. So we need to move the clock’s hands to better reflect noon (when the Sun is directly overhead) for a given region. The further away eastward/westward from the UTC line in west Europe/Africa the larger the offset.

A time zone is a set of rules for handling adjustments and anomalies as practiced by a local community or region. The most common anomaly is the all-too-popular lunacy known as Daylight Saving Time (DST).

A time zone has the history of past rules, present rules, and rules confirmed for the near future.

These rules change more often than you might expect. Be sure to keep your date-time library's rules, usually a copy of the 'tz' database, up to date. Keeping up-to-date is easier than ever now in Java 8 with Oracle releasing a Timezone Updater Tool.

Specify a proper time zone name in the format of Continent/Region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 2-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

Time Zone = Offset + Rules of Adjustments

ZoneId z = ZoneId.of( “Africa/Tunis” ) ; 

ZonedDateTime

Think of ZonedDateTime conceptually as an Instant with an assigned ZoneId.

ZonedDateTime = ( Instant + ZoneId )

To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone):

ZonedDateTime zdt = ZonedDateTime.now( z ) ;  // Pass a `ZoneId` object such as `ZoneId.of( "Europe/Paris" )`. 

Nearly all of your backend, database, business logic, data persistence, data exchange should all be in UTC. But for presentation to users you need to adjust into a time zone expected by the user. This is the purpose of the ZonedDateTime class and the formatter classes used to generate String representations of those date-time values.

ZonedDateTime zdt = instant.atZone( z ) ;
String output = zdt.toString() ;                 // Standard ISO 8601 format.

You can generate text in localized format using DateTimeFormatter.

DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL ).withLocale( Locale.CANADA_FRENCH ) ; 
String outputFormatted = zdt.format( f ) ;

LocalDate, LocalTime, LocalDateTime

The "local" date time classes, LocalDateTime, LocalDate, LocalTime, are a different kind of critter. The are not tied to any one locality or time zone. They are not tied to the timeline. They have no real meaning until you apply them to a locality to find a point on the timeline.

The word “Local” in these class names may be counter-intuitive to the uninitiated. The word means any locality, or every locality, but not a particular locality.

So for business apps, the "Local" types are not often used as they represent just the general idea of a possible date or time not a specific moment on the timeline. Business apps tend to care about the exact moment an invoice arrived, a product shipped for transport, an employee was hired, or the taxi left the garage. So business app developers use Instant and ZonedDateTime classes most commonly.

So when would we use LocalDateTime? In three situations:

• We want to apply a certain date and time-of-day across multiple locations.
• We are booking appointments.
• We have an intended yet undetermined time zone.

Notice that none of these three cases involve a single certain specific point on the timeline, none of these are a moment.

One time-of-day, multiple moments

Sometimes we want to represent a certain time-of-day on a certain date, but want to apply that into multiple localities across time zones.

For example, "Christmas starts at midnight on the 25th of December 2015" is a LocalDateTime. Midnight strikes at different moments in Paris than in Montréal, and different again in Seattle and in Auckland.

LocalDate ld = LocalDate.of( 2018 , Month.DECEMBER , 25 ) ;
LocalTime lt = LocalTime.MIN ;   // 00:00:00
LocalDateTime ldt = LocalDateTime.of( ld , lt ) ;  // Christmas morning anywhere. 

Another example, "Acme Company has a policy that lunchtime starts at 12:30 PM at each of its factories worldwide" is a LocalTime. To have real meaning you need to apply it to the timeline to figure the moment of 12:30 at the Stuttgart factory or 12:30 at the Rabat factory or 12:30 at the Sydney factory.

Booking appointments

Another situation to use LocalDateTime is for booking future events (ex: Dentist appointments). These appointments may be far enough out in the future that you risk politicians redefining the time zone. Politicians often give little forewarning, or even no warning at all. If you mean "3 PM next January 23rd" regardless of how the politicians may play with the clock, then you cannot record a moment – that would see 3 PM turn into 2 PM or 4 PM if that region adopted or dropped Daylight Saving Time, for example.

For appointments, store a LocalDateTime and a ZoneId, kept separately. Later, when generating a schedule, on-the-fly determine a moment by calling LocalDateTime::atZone( ZoneId ) to generate a ZonedDateTime object.

ZonedDateTime zdt = ldt.atZone( z ) ;  // Given a date, a time-of-day, and a time zone, determine a moment, a point on the timeline.

If needed, you can adjust to UTC. Extract an Instant from the ZonedDateTime.

Instant instant = zdt.toInstant() ;  // Adjust from some zone to UTC. Same moment, same point on the timeline, different wall-clock time.

Unknown zone

Some people might use LocalDateTime in a situation where the time zone or offset is unknown.

I consider this case inappropriate and unwise. If a zone or offset is intended but undetermined, you have bad data. That would be like storing a price of a product without knowing the intended currency (dollars, pounds, euros, etc.). Not a good idea.

All date-time types

For completeness, here is a table of all the possible date-time types, both modern and legacy in Java, as well as those defined by the SQL standard. This might help to place the Instant & LocalDateTime classes in a larger context.

Notice the odd choices made by the Java team in designing JDBC 4.2. They chose to support all the java.time times… except for the two most commonly used classes: Instant & ZonedDateTime.

But not to worry. We can easily convert back and forth.

Converting Instant.

// Storing
OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC ) ;
myPreparedStatement.setObject( … , odt ) ;

// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
Instant instant = odt.toInstant() ;

Converting ZonedDateTime.

// Storing
OffsetDateTime odt = zdt.toOffsetDateTime() ;
myPreparedStatement.setObject( … , odt ) ;

// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
ZoneId z = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = odt.atZone( z ) ; 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

local::lib will help you. It will convince "make install" (and "Build install") to install to a directory you can write to, and it will tell perl how to get at those modules.

In general, if you want to use a module that is in a blib/ directory, you want to say perl -Mblib ... where ... is how you would normally invoke your script.

1. Create a new folder in Drive and share it as "Public on the web."
2. Upload your content files to this folder.
3. Right click on your folder and click on Details.
4. Copy Hosting URL and paste it on your browser.(e.g. https://googledrive.com/host/0B716ywBKT84AcHZfMWgtNk5aeXM)
5. It will launch index.html if it exist in your folder other wise list all files in your folder.

Here's a simple way

for (i in 1:10) {
  
  skip_to_next <- FALSE
  
  # Note that print(b) fails since b doesn't exist
  
  tryCatch(print(b), error = function(e) { skip_to_next <<- TRUE})
  
  if(skip_to_next) { next }     
}

Note that the loop completes all 10 iterations, despite errors. You can obviously replace print(b) with any code you want. You can also wrap many lines of code in { and } if you have more than one line of code inside the tryCatch

You didn't add any width or content to the elements. Also you should set padding top and bottom to your main element so the content is not hidden behind the header/footer. You can remove the height as well and let the browser decide based on the content.

http://jsfiddle.net/BrmGr/12/

.header{
position: fixed;
background-color: #f00;
height: 100px;
    width:100%;
}
.main{
background-color: #ff0;
    padding-top: 100px;
    padding-bottom: 120px;
}
.footer{
position: fixed;
bottom: 0;
background-color: #f0f;
height: 120px;
    width:100%;}

This answer is a little variance for the question. Sometimes, we only need the sql only for debug purposes in runtime. In that case, there are a more easy way, using debug on editors.

• Put a breakpoint on org.hibernate.loader.Loader.loadEntityBatch (or navigate on the stack until there);
• When execution is suspended, look the value of variable this.sql ;

This is for hibernate 3. I'm not sure that this work on other versions.

As an aside, when trying to diagnose a similar bug I realised that jquery's ajax error callback returns a status of "timeout" if it failed due to a timeout.

Here's an example:

$.ajax({
    url: "/ajax_json_echo/",
    timeout: 500,
    error: function(jqXHR, textStatus, errorThrown) {
        alert(textStatus); // this will be "timeout"
    }
});

Here it is on jsfiddle.

in laravel 5 first we need to create migration and then run the migration

Step 1.

php artisan make:migration create_users_table --create=users

Step 2.

php artisan migrate

This happens if you initialized a new github repo with README and/or LICENSE file

git remote add origin [//your github url]

//pull those changes

git pull origin master 

// or optionally, 'git pull origin master --allow-unrelated-histories' if you have initialized repo in github and also committed locally

//now, push your work to your new repo

git push origin master

Now you will be able to push your repository to github. Basically, you have to merge those new initialized files with your work. git pull fetches and merges for you. You can also fetch and merge if that suits you.

I would also suggest looking at the "libphonenumber" Google Library. I know it is not regex but it does exactly what you want.

For example, it will recognize that:

15555555555

is a possible number but not a valid number. It also supports countries outside the US.

Highlights of functionality:

• Parsing/formatting/validating phone numbers for all countries/regions of the world.
• getNumberType - gets the type of the number based on the number itself; able to distinguish Fixed-line, Mobile, Toll-free, Premium Rate, Shared Cost, VoIP and Personal Numbers (whenever feasible).
• isNumberMatch - gets a confidence level on whether two numbers could be the same.
• getExampleNumber/getExampleNumberByType - provides valid example numbers for all countries/regions, with the option of specifying which type of example phone number is needed.
• isPossibleNumber - quickly guessing whether a number is a possible phonenumber by using only the length information, much faster than a full validation.
• isValidNumber - full validation of a phone number for a region using length and prefix information.
• AsYouTypeFormatter - formats phone numbers on-the-fly when users enter each digit.
• findNumbers - finds numbers in text input.
• PhoneNumberOfflineGeocoder - provides geographical information related to a phone number.

Examples

The biggest problem with phone number validation is it is very culturally dependant.

• America
  • (408) 974–2042 is a valid US number
  • (999) 974–2042 is not a valid US number
• Australia
  • 0404 999 999 is a valid Australian number
  • (02) 9999 9999 is also a valid Australian number
  • (09) 9999 9999 is not a valid Australian number

A regular expression is fine for checking the format of a phone number, but it's not really going to be able to check the validity of a phone number.

I would suggest skipping a simple regular expression to test your phone number against, and using a library such as Google's libphonenumber (link to GitHub project).

Introducing libphonenumber!

Using one of your more complex examples, 1-234-567-8901 x1234, you get the following data out of libphonenumber (link to online demo):

Validation Results

Result from isPossibleNumber()  true
Result from isValidNumber()     true

Formatting Results:

E164 format                    +12345678901
Original format                (234) 567-8901 ext. 123
National format                (234) 567-8901 ext. 123
International format           +1 234-567-8901 ext. 123
Out-of-country format from US  1 (234) 567-8901 ext. 123
Out-of-country format from CH  00 1 234-567-8901 ext. 123

So not only do you learn if the phone number is valid (which it is), but you also get consistent phone number formatting in your locale.

As a bonus, libphonenumber has a number of datasets to check the validity of phone numbers, as well, so checking a number such as +61299999999 (the international version of (02) 9999 9999) returns as a valid number with formatting:

Validation Results

Result from isPossibleNumber()  true
Result from isValidNumber()     true

Formatting Results

E164 format                    +61299999999
Original format                61 2 9999 9999
National format                (02) 9999 9999
International format           +61 2 9999 9999
Out-of-country format from US  011 61 2 9999 9999
Out-of-country format from CH  00 61 2 9999 9999

libphonenumber also gives you many additional benefits, such as grabbing the location that the phone number is detected as being, and also getting the time zone information from the phone number:

PhoneNumberOfflineGeocoder Results
Location        Australia

PhoneNumberToTimeZonesMapper Results
Time zone(s)    [Australia/Sydney]

But the invalid Australian phone number ((09) 9999 9999) returns that it is not a valid phone number.

Validation Results

Result from isPossibleNumber()  true
Result from isValidNumber()     false

Google's version has code for Java and Javascript, but people have also implemented libraries for other languages that use the Google i18n phone number dataset:

Unless you are certain that you are always going to be accepting numbers from one locale, and they are always going to be in one format, I would heavily suggest not writing your own code for this, and using libphonenumber for validating and displaying phone numbers.

you can find more details about the Popup Control from MSDN documentation.

MSDN documentation on Popup control

There is an internal Bash variable called $PIPESTATUS; it’s an array that holds the exit status of each command in your last foreground pipeline of commands.

<command> | tee out.txt ; test ${PIPESTATUS[0]} -eq 0

Or another alternative which also works with other shells (like zsh) would be to enable pipefail:

set -o pipefail
...

The first option does not work with zsh due to a little bit different syntax.

Problem statement = No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? intellij

Solution

Please set the Environment variable like below to solve the issue

Variable name : JAVA_HOME

Variable Value : C:\Program Files\Java\jdk1.8.0_202

Variable name : M2_HOME

Variable Value : C:\Program Files\apache-maven-3.6.0

Moreover, Add Java and maven path in "System Variables" like below:

1. C:\Program Files\Java\jdk1.8.0_202\bin

2. C:\Program Files\apache-maven-3.6.0\bin

The subprocess module is the preferred way of running other programs from Python -- much more flexible and nicer to use than os.system.

import subprocess
#subprocess.check_output(['ls', '-l'])  # All that is technically needed...
print(subprocess.check_output(['ls', '-l']))

Using the -n /usr/local/bin flag does work, BUT I had to come back to this page every time I wanted to update a package again. So I figured out a permanent fix for this.

For those interested in fixing this permanently:

Create a ~/.gemrc file

vim .gemrc

With the following content:

:gemdir:
   - ~/.gem/ruby
install: -n /usr/local/bin

Now you can run your command normally without the -n flag.

Enjoy!

If you want to set in imageview an image that is inside the mipmap dirs you can do it like this:

myImageView.setImageDrawable(getResources().getDrawable(R.mipmap.my_picture)

A simple solution is to install jshon library :

jshon -l < /tmp/test.json

This is the problem about Multidex . You can try to remove some jar, or you can try like this : http://developer.android.com/tools/building/multidex.html#mdex-gradle in app build.gradle :

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

In your manifest :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

Yes. You can use reg.exe which comes with the OS to add, delete or query registry values. Reg.exe does not have an explicit modify command, but you can do it by doing delete and then add.

In objectMapper we have writeValueAsString() which accepts object as parameter. We can pass object list as parameter get the string back.

List<Apartment> aptList =  new ArrayList<Apartment>();
    Apartment aptmt = null;
    for(int i=0;i<5;i++){
         aptmt= new Apartment();
         aptmt.setAptName("Apartment Name : ArrowHead Ranch");
         aptmt.setAptNum("3153"+i);
         aptmt.setPhase((i+1));
         aptmt.setFloorLevel(i+2);
         aptList.add(aptmt);
    }
mapper.writeValueAsString(aptList)

Cursors are a mechanism to explicitly enumerate through the rows of a result set, rather than retrieving it as such.

However, while they may be more comfortable to use for programmers accustomed to writing While Not RS.EOF Do ..., they are typically a thing to be avoided within SQL Server stored procedures if at all possible -- if you can write a query without the use of cursors, you give the optimizer a much better chance to find a fast way to implement it.

In all honesty, I've never found a realistic use case for a cursor that couldn't be avoided, with the exception of a few administrative tasks such as looping over all indexes in the catalog and rebuilding them. I suppose they might have some uses in report generation or mail merges, but it's probably more efficient to do the cursor-like work in an application that talks to the database, letting the database engine do what it does best -- set manipulation.

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

To start the MySQL service, you can remove '/var/lib/mysql/mysql.sock' and start the MySQL service again:

Remove the socket file:

[root@server ~]# rm /var/lib/mysql/mysql.sock
rm: remove socket `/var/lib/mysql/mysql.sock'? yes

Start the MySQL service:

[root@server~]# service mysqld start
Starting mysqld:                                           [  OK  ]

It will help you to resolve your problem.

(Neither IN nor ANY is an "operator". A "construct" or "syntax element".)

Logically, quoting the manual:

IN is equivalent to = ANY.

But there are two syntax variants of IN and two variants of ANY. Details:

• How to use ANY instead of IN in a WHERE clause with Rails?

IN taking a set is equivalent to = ANY taking a set, as demonstrated here:

• postgreSQL - in vs any

But the second variant of each is not equivalent to the other. The second variant of the ANY construct takes an array (must be an actual array type), while the second variant of IN takes a comma-separated list of values. This leads to different restrictions in passing values and can also lead to different query plans in special cases:

• Index not used with =any() but used with in
• Pass multiple sets or arrays of values to a function

ANY is more versatile

The ANY construct is far more versatile, as it can be combined with various operators, not just =. Example:

SELECT 'foo' LIKE ANY('{FOO,bar,%oo%}');

For a big number of values, providing a set scales better for each:

• Optimizing a Postgres query with a large IN

Related:

• Can PostgreSQL index array columns?

Inversion / opposite / exclusion

"Find rows where id is in the given array":

SELECT * FROM tbl WHERE id = ANY (ARRAY[1, 2]);

Inversion: "Find rows where id is not in the array":

SELECT * FROM tbl WHERE id <> ALL (ARRAY[1, 2]);
SELECT * FROM tbl WHERE id <> ALL ('{1, 2}');  -- equivalent array literal
SELECT * FROM tbl WHERE NOT (id = ANY ('{1, 2}'));

All three equivalent. The first with array constructor, the other two with array literal. The data type can be derived from context unambiguously. Else, an explicit cast may be required, like '{1,2}'::int[].

Rows with id IS NULL do not pass either of these expressions. To include NULL values additionally:

SELECT * FROM tbl WHERE (id = ANY ('{1, 2}')) IS NOT TRUE;

I know the question is about GCC, but I thought it might be useful to have some information about compilers other compilers as well.

GCC's noinline function attribute is pretty popular with other compilers as well. It is supported by at least:

• Clang (check with __has_attribute(noinline))
• Intel C/C++ Compiler (their documentation is terrible, but I'm certain it works on 16.0+)
• Oracle Solaris Studio back to at least 12.2
• ARM C/C++ Compiler back to at least 4.1
• IBM XL C/C++ back to at least 10.1
• TI 8.0+ (or 7.3+ with --gcc, which will define __TI_GNU_ATTRIBUTE_SUPPORT__)

Additionally, MSVC supports __declspec(noinline) back to Visual Studio 7.1. Intel probably supports it too (they try to be compatible with both GCC and MSVC), but I haven't bothered to verify that. The syntax is basically the same:

__declspec(noinline)
static void foo(void) { }

PGI 10.2+ (and probably older) supports a noinline pragma which applies to the next function:

#pragma noinline
static void foo(void) { }

TI 6.0+ supports a FUNC_CANNOT_INLINE pragma which (annoyingly) works differently in C and C++. In C++, it's similar to PGI's:

#pragma FUNC_CANNOT_INLINE;
static void foo(void) { }

In C, however, the function name is required:

#pragma FUNC_CANNOT_INLINE(foo);
static void foo(void) { }

Cray 6.4+ (and possibly earlier) takes a similar approach, requiring the function name:

#pragma _CRI inline_never foo
static void foo(void) { }

Oracle Developer Studio also supports a pragma which takes the function name, going back to at least Forte Developer 6, but note that it needs to come after the declaration, even in recent versions:

static void foo(void);
#pragma no_inline(foo)

Depending on how dedicated you are, you could create a macro that would work everywhere, but you would need to have the function name as well as the declaration as arguments.

If, OTOH, you're okay with something that just works for most people, you can get away with something which is a little more aesthetically pleasing and doesn't require repeating yourself. That's the approach I've taken for Hedley, where the current version of HEDLEY_NEVER_INLINE looks like:

#if \
  HEDLEY_GNUC_HAS_ATTRIBUTE(noinline,4,0,0) || \
  HEDLEY_INTEL_VERSION_CHECK(16,0,0) || \
  HEDLEY_SUNPRO_VERSION_CHECK(5,11,0) || \
  HEDLEY_ARM_VERSION_CHECK(4,1,0) || \
  HEDLEY_IBM_VERSION_CHECK(10,1,0) || \
  HEDLEY_TI_VERSION_CHECK(8,0,0) || \
  (HEDLEY_TI_VERSION_CHECK(7,3,0) && defined(__TI_GNU_ATTRIBUTE_SUPPORT__))
#  define HEDLEY_NEVER_INLINE __attribute__((__noinline__))
#elif HEDLEY_MSVC_VERSION_CHECK(13,10,0)
#  define HEDLEY_NEVER_INLINE __declspec(noinline)
#elif HEDLEY_PGI_VERSION_CHECK(10,2,0)
#  define HEDLEY_NEVER_INLINE _Pragma("noinline")
#elif HEDLEY_TI_VERSION_CHECK(6,0,0)
#  define HEDLEY_NEVER_INLINE _Pragma("FUNC_CANNOT_INLINE;")
#else
#  define HEDLEY_NEVER_INLINE HEDLEY_INLINE
#endif

If you don't want to use Hedley (it's a single public domain / CC0 header) you can convert the version checking macros without too much effort, but more than I'm willing to put in ?.

You can try Cactoos:

InputStream stream = new InputStreamOf(str);

Then, if you need a Reader:

Reader reader = new ReaderOf(stream);

A proven solution for Visual Studio extension for Data Tools for Business Intelligence (SSDT-BI 2013):

1. Move the Project folder to its new location (don't rename anything yet)
2. In Solution Explorer, rename the Project / Solution.
3. Close (and save) the newly-renamed project.
4. Rename the project's folder and .sln file.
5. Use a text editor and open the newly-renamed project solution file (.sln) (I used Notepad++)
6. In line number 6 you'll see: "Project {fdjfksdjk4387!...} = "OLDPROJECT", "OLDFOLDER\OLDPROJECT.rptproj". Rename everything with the new names used in step 4. (i.e. ... = "NEWPROJECT", "NEWFOLDER\NEWPROJECT.rptproj"... )
7. That's it!

It was tested 100% and worked flawlessly in my case.

NOTE: I can't confirm if it works under different project templates and other Visual Studio versions. As always, do backup everything beforehand.

Alex Yao's Answer is the simplest solution, if you just want to build and run Java program w/o taking any input from the console use the solution provided by Alex Yao. However if you would like to take input from the console then refer to the following link

Java console input in Sublime Text 2?

you can use pattern matcher as well, which will replace all in one shot.

Pattern keyPattern = Pattern.compile(key); Matcher matcher = keyPattern.matcher(str); String nerSrting = matcher.replaceAll(value);

you can also just use return:

   function outer() { 
    function inner() {
        alert("hi");
    }
return inner();

}
outer();

var el = document.getElementById('foo');
el.parentNode.innerHTML;

FireFox have problemes for getBBox(), i need to do this in vanillaJS.

I've a better Way and is the same result as real svg.getBBox() function !

With this good post : Get the real size of a SVG/G element

var el   = document.getElementById("yourElement"); // or other selector like querySelector()
var rect = el.getBoundingClientRect(); // get the bounding rectangle

console.log( rect.width );
console.log( rect.height);

If the previously mentioned higher z-indexing in parent nodes wont suit your needs, you can create alternative solution and target it to problematic browsers either by IE conditional comments or using the (more idealistic) feature detection provided by Modernizr.

Quick (and obviously working) test for Modernizr:

Modernizr.addTest('compliantzindex', function(){
    var test  = document.createElement('div'),
        fake = false,
        root = document.body || (function () {
            fake = true;
            return document.documentElement.appendChild(document.createElement('body'));
        }());

    root.appendChild(test);
    test.style.position = 'relative';
    var ret = (test.style.zIndex !== 0);
    root.removeChild(test);

    if (fake) {
        document.documentElement.removeChild(root);
    }

    return ret;
});

$('#test').attr('checked','checked');

$('#test').removeAttr('checked');

<select name="country" formControlName="country" id="country" 
       class="formcontrol form-control-element" [(ngModel)]="country">
   <option value="90">Turkey</option>
   <option value="1">USA</option>
   <option value="30">Greece</option>
</select>

name="country"
formControlName="country" 
[(ngModel)]="country" 

Those are the three things need to use ngModel inside a formGroup directive.

Note that same name should be used.

This comment on this page worked for me and a few others. It deserves its own answer:

python manage.py migrate --run-syncdb

Well, this should really be broken into 2 parts:

1. Can you pair 2 Bluetooth devices without going through a Bluetooth pairing handshake? No, you can't. That's baked into the protocol so there is no way around this.
2. Can you perform the handshake without a user interface? Yes, you can: that's just code.

I'm not sure how you do it in Windows land, but in *nix land there are functions buried in the Bluez stack that let you receive notifications about when a new device appears, and send it the pairing code (clearly there have to be these functions: those are what the user interface use). Given sufficient time and experience I'm sure you could figure out how to write your own version of the Bluetooth Settings app that somehow:

• Detected a new device had arrived
• Looked at the name/bluetooth mac address and checked some internal database for the pairing code to use.
• Sent the pairing code and completed the operation

All without having to pop up a user interface.

If you go ahead and write the code I'd LOVE to get my hands on it.

Below code(jQuery.isEmptyObject(anyObject) function is already provided) works perfectly fine, no need to write one of your own.

   // works for any Object Including JSON(key value pair) or Array.
  //  var arr = [];
  //  var jsonObj = {};
    if (jQuery.isEmptyObject(anyObjectIncludingJSON))
    {
       console.log("Empty Object");
    }

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

You can install them by

sudo apt-get install -y libav-tools

After changing main port from 80 to 8080 you have to change the config in XAMPP control panel as I show in the images:

1)

2)

3)

Then restart the service and that's it !

You have to distinct sub routines and functions in vba... Generally (as far as I know), sub routines do not return anything and the surrounding parantheses are optional. For functions, you need to write the parantheses.

As for your example, MsgBox is not a function but a sub routine and therefore the parantheses are optional in that case. One exception with functions is, when you do not assign the returned value, or when the function does not consume a parameter, you can leave away the parantheses too.

This answer goes into a bit more detail, but basically you should be on the save side, when you provide parantheses for functions and leave them away for sub routines.

All these suggestions work unless you put the anchors inside an UL list.

<ul>
    <li>
        <a>click me</a>>
    </li>
</ul>

Then any cascade style sheet rules are overridden in the Chrome browser. The width becomes auto. Then you must use inline CSS rules directly on the anchor itself.

See this answer here. You need to redirect all routes that Node is not using to Angular:

app.get('*', function(req, res) {
  res.sendfile('./server/views/index.html')
})

onload event handler must be inside popup's HTML <body> markup.

First check the default-jdk package, good chance it already provide you an OpenJDK >= 11.
ref: https://packages.ubuntu.com/search?keywords=default-jdk&searchon=names&suite=all&section=all

Ubuntu 18.04 LTS +

So starting from Ubuntu 18.04 LTS it should be ok.

sudo apt update -qq
sudo apt install -yq default-jdk

note: don't forget to set JAVA_HOME

export JAVA_HOME=/usr/lib/jvm/default-java
mvn -version

Ubuntu 16.04 LTS

For Ubuntu 16.04 LTS, only openjdk-8-jdk is provided in the official repos so you need to find it in a ppa:

sudo add-apt-repository -y ppa:openjdk-r/ppa
sudo apt update -qq
sudo apt install -yq openjdk-11-jdk

note: don't forget to set JAVA_HOME

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
mvn -version

Here is the code to set up a MediaPlayer to play off of the SD card:

String PATH_TO_FILE = "/sdcard/music.mp3";    
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(PATH_TO_FILE);
mediaPlayer.prepare();   
mediaPlayer.start()

You can see the full example here. Let me know if you have any problems.

• getattr(x, 'y') is equivalent to x.y
• setattr(x, 'y', v) is equivalent to x.y = v
• delattr(x, 'y') is equivalent to del x.y

The middle one writes to the pipeline. Write-Host and Out-Host writes to the console. 'echo' is an alias for Write-Output which writes to the pipeline as well. The best way to write to the console would be using the Write-Host cmdlet.

When an object is written to the pipeline it can be consumed by other commands in the chain. For example:

"hello world" | Do-Something

but this won't work since Write-Host writes to the console, not to the pipeline (Do-Something will not get the string):

Write-Host "hello world" | Do-Something

Also, your compare function is incorrect. It needs to return -1, 0, or 1, not a boolean as you have it. The correct compare function would be:

def compare(item1, item2):
    if fitness(item1) < fitness(item2):
        return -1
    elif fitness(item1) > fitness(item2):
        return 1
    else:
        return 0

# Calling
list.sort(key=compare)

Actually I tried creating empty stdClass and compared the speed to empty class.

class emp{}

then proceeded creating 1000 stdClasses and emps... empty classes were done in around 1100 microseconds while stdClasses took over 1700 microseconds. So I guess its better to create your own dummy class for storing data if you want to use objects for that so badly (arrays are a lot faster for both writing and reading).

You can use Get-Member

if(Get-Member -inputobject $var -name "Property" -Membertype Properties){
#Property exists
}

Set environment variables for JAVA_HOME and JRE_HOME without the \bin. That worked for me

I've tried all above and [readr][1] made the best job. I have only 8gb RAM

Loop for 20 files, 5gb each, 7 columns:

read_fwf(arquivos[i],col_types = "ccccccc",fwf_cols(cnpj = c(4,17), nome = c(19,168), cpf = c(169,183), fantasia = c(169,223), sit.cadastral = c(224,225), dt.sitcadastral = c(226,233), cnae = c(376,382)))

I know this is an old question, but I stumbled across it when I was having a similar issue, and just wanted to share how I ended achieving the results you requested so future people can pick what works best for their situation.

First, I utilize the onsubmit event in the form, and pass this to the function to make it easier to deal with this particular form.

<form action="/system/wpacert" onsubmit="return closeSelf(this);" method="post" enctype="multipart/form-data"  name="certform">
    <div>Certificate 1: <input type="file" name="cert1"/></div>
    <div>Certificate 2: <input type="file" name="cert2"/></div>
    <div>Certificate 3: <input type="file" name="cert3"/></div>

    <div><input type="submit" value="Upload"/></div>
</form>

In our function, we'll submit the form data, and then we'll close the window. This will allow it to submit the data, and once it's done, then it'll close the window and return you to your original window.

<script type="text/javascript">
  function closeSelf (f) {
     f.submit();
     window.close();
  }
</script>

Hope this helps someone out. Enjoy!

Option 2: This option will let you submit via AJAX, and if it's successful, it'll close the window. This prevents windows from closing prior to the data being submitted. Credits to http://jquery.malsup.com/form/ for their work on the jQuery Form Plugin

First, remove your onsubmit/onclick events from the form/submit button. Place an ID on the form so AJAX can find it.

<form action="/system/wpacert" method="post" enctype="multipart/form-data"  id="certform">
    <div>Certificate 1: <input type="file" name="cert1"/></div>
    <div>Certificate 2: <input type="file" name="cert2"/></div>
    <div>Certificate 3: <input type="file" name="cert3"/></div>

    <div><input type="submit" value="Upload"/></div>
</form>

Second, you'll want to throw this script at the bottom, don't forget to reference the plugin. If the form submission is successful, it'll close the window.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script> 
<script src="http://malsup.github.com/jquery.form.js"></script> 

    <script>
       $(document).ready(function () {
          $('#certform').ajaxForm(function () {
          window.close();
          });
       });
    </script>

Is there any possible way to change the color of a font-awesome icon to black?

Yes, there is. See the snipped bellow

<!-- Assuming that you don't have, this needs to be in your HTML file (usually the header) -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

<!-- Here is what you need to use -->
<a href="/users/edit" class="fa fa-cog" style="color:black"> Edit Profile</a>

Font awesome is supposed to be font not image, right?

Yes, it is a font. Therefore, you are able to scale it to any size without losing quality.

Even though you've got your answer, for those that find this question, it is also possible to open an Excel spreadsheet as a JET data store. Borrowing the connection string from a project I've used it on, it will look kinda like this:

strExcelConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & objFile.Path & ";Extended Properties=""Excel 8.0;HDR=Yes"""
strSQL = "SELECT * FROM [RegistrationList$] ORDER BY DateToRegister DESC"

Note that "RegistrationList" is the name of the tab in the workbook. There are a few tutorials floating around on the web with the particulars of what you can and can't do accessing a sheet this way.

Just thought I'd add. :)

Directly calling a URL to get an image may concern with major security issues. You need to ensure that you have sufficient rights to access that resource. However You can use ByteOutputStream to read image file. This is an example (Its just an example, you need to do necessary changes as per your requirement.)

ByteArrayOutputStream bis = new ByteArrayOutputStream();
InputStream is = null;
try {
  is = url.openStream ();
  byte[] bytebuff = new byte[4096]; 
  int n;

  while ( (n = is.read(bytebuff)) > 0 ) {
    bis.write(bytebuff, 0, n);
  }
}

From the git-diff manpage:

git diff [--options] <commit> <commit> [--] [<path>...]

For instance, to see the difference for a file "main.c" between now and two commits back, here are three equivalent commands:

$ git diff HEAD^^ HEAD main.c
$ git diff HEAD^^..HEAD -- main.c
$ git diff HEAD~2 HEAD -- main.c

I've used the jdbcsql project on Sourceforge.

On *nix systems, this will create a csv stream of results to standard out:

java -Djava.security.egd=file///dev/urandom -jar jdbcsql.jar -d oracledb_SID -h $host -p 1521 -U some_username -m oracle -P "$PW" -f excel -s "," "$1"

Note that adding the -Djava.security.egd=file///dev/urandom increases performance greatly

Windows commands are similar: see http://jdbcsql.sourceforge.net/

.card-img-top {
width: 100%;
height: 30vh;
object-fit: contain;
}

Contain will help in getting Complete Image displayed inside Card.

Adjust height "30vh" according to your need!

The whole point of using a mapping technology like Jackson is that you can use Objects (you don't have to parse the JSON yourself).

Define a Java class that resembles the JSON you will be expecting.

e.g. this JSON:

{
"foo" : ["abc","one","two","three"],
"bar" : "true",
"baz" : "1"
}

could be mapped to this class:

public class Fizzle{
    private List<String> foo;
    private boolean bar;
    private int baz;
    // getters and setters omitted
}

Now if you have a Controller method like this:

@RequestMapping("somepath")
@ResponseBody
public Fozzle doSomeThing(@RequestBody Fizzle input){
    return new Fozzle(input);
}

and you pass in the JSON from above, Jackson will automatically create a Fizzle object for you, and it will serialize a JSON view of the returned Object out to the response with mime type application/json.

For a full working example see this previous answer of mine.

Position the div relatively, and position the ribbon absolutely inside it. Something like:

#content {
  position:relative;
}

.ribbon {
  position:absolute;
  top:0;
  right:0;
}

did you try 'localhost/phpmyadmin' ? (notice the lowercase)

PHPMyAdmin tends to have inconsistent directory names across its versions/distributions.

Edit: Confirm the URL by checking the name of the root folder!

If the config was the primary issue (and it may still be nthary) you would get a php error, not a http "Object not found" error,

As for the config error, here are some steps to correct it:

1. Once you have confirmed which case your PHPMyAdmin is in, confirm that your config.inc.php is located in its root directory.

2. If it is, rename it to something else as a backup. Then copy the config.sample.inc.php (in the same directory) and rename it to config.inc.php

3. Check if it works.

4. If its does, then open up both the new config.inc.php (that works) and the backup you took earlier of your old one. Compare them and copy/replace the important parts that you want to carry over, the file (in its default state) isn't that long and it should be relatively easy to do so.

N.B. If the reason that you want your old config is because of security setup that you once had, I would definitely suggest still using the security wizard built into XAMPP so that you can be assured that you have the right configuration for the right version. There is no guarantee that different XAMPP/PHPMyAdmin versions implement security/anything in the same way.

XAMPP Security Wizard

C99 does, if you have

#include <stdbool.h> 

If the compiler does not support C99, you can define it yourself:

// file : myboolean.h
#ifndef MYBOOLEAN_H
#define MYBOOLEAN_H

#define false 0
#define true 1
typedef int bool; // or #define bool int

#endif

(but note that this definition changes ABI for bool type so linking against external libraries which were compiled with properly defined bool may cause hard-to-diagnose runtime errors).

I tried every thing, but still I was unable to do that, I am using mysql, jpa with hibernate, I resolved my issue by assigning value of id 0 in constructor Following is my id declaration code

@Id
@Column(name="id",updatable=false,nullable=false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

I think I found why there are a few varying answers for this question. When the window has been resized such that it has a horizontal scroll bar (because the buffer is larger than the window) Console.CursorTop seems to return the wrong line. The following code works for me, regardless of window size or cursor position.

public static void ClearLine()
{
    Console.SetCursorPosition(0, Console.CursorTop);
    Console.Write(new string(' ', Console.WindowWidth));
    Console.SetCursorPosition(0, Console.CursorTop - (Console.WindowWidth >= Console.BufferWidth ? 1 : 0));
}

Without the (Console.WindowWidth >= Console.BufferWidth ? 1 : 0), the code may either move the cursor up or down, depending on which version you use from this page, and the state of the window.

Adding that completionHandler line to delegate method solved same problem for me:

//Called when a notification is delivered to a foreground app.
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

completionHandler([.alert, .badge, .sound])
} 

Just reading the file into an array, one line per element, is trivial:

open my $handle, '<', $path_to_file;
chomp(my @lines = <$handle>);
close $handle;

Now the lines of the file are in the array @lines.

If you want to make sure there is error handling for open and close, do something like this (in the snipped below, we open the file in UTF-8 mode, too):

my $handle;
unless (open $handle, "<:encoding(utf8)", $path_to_file) {
   print STDERR "Could not open file '$path_to_file': $!\n";
   # we return 'undefined', we could also 'die' or 'croak'
   return undef
}
chomp(my @lines = <$handle>);
unless (close $handle) {
   # what does it mean if close yields an error and you are just reading?
   print STDERR "Don't care error while closing '$path_to_file': $!\n";
} 

you can use CASE WHEN as follow as achieve the as IF ELSE.

SELECT FROM A a 
LEFT JOIN B b 
ON a.col1 = b.col1 
AND (CASE 
        WHEN a.col2 like '0%' then TRIM(LEADING '0' FROM a.col2)
        ELSE substring(a.col2,1,2)
    END
)=b.col2; 

p.s:just in case somebody needs this way.

1. Either upgrade to gulp 4 Or Else
2. downgrade to an earlier node version.

One way would be hg rollback (deprecated as of Hg2.7, August 2013)

Please use hg commit --amend instead of rollback to correct mistakes in the last commit.

Roll back the last transaction in a repository.

When committing or merging, Mercurial adds the changeset entry last.
Mercurial keeps a transaction log of the name of each file touched and its length prior to the transaction. On abort, it truncates each file to its prior length. This simplicity is one benefit of making revlogs append-only. The transaction journal also allows an undo operation.

See TortoiseHg Recovery section:

This thread also details the difference between hg rollback and hg strip:
(written by Martin Geisler who also contributes on SO)

• 'hg rollback' will remove the last transaction. Transactions are a concept often found in databases. In Mercurial we start a transaction when certain operations are run, such as commit, push, pull...
  When the operation finishes succesfully, the transaction is marked as complete. If an error occurs, the transaction is "rolled back" and the repository is left in the same state as before.
  You can manually trigger a rollback with 'hg rollback'. This will undo the last transactional command. If a pull command brought 10 new changesets into the repository on different branches, then 'hg rollback' will remove them all. Please note: there is no backup when you rollback a transaction!

• 'hg strip' will remove a changeset and all its descendants. The changesets are saved as a bundle, which you can apply again if you need them back.

ForeverWintr suggests in the comments (in 2016, 5 years later)

You can 'un-commit' files by first hg forgetting them, e.g.: hg forget filea; hg commit --amend, but that seems unintuitive.
hg strip --keep is probably a better solution for modern hg.

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

Using ignore Duplicates on the unique index as suggested by IanC here was my solution for a similar issue, creating the index with the Option WITH IGNORE_DUP_KEY

In backward compatible syntax
, WITH IGNORE_DUP_KEY is equivalent to WITH IGNORE_DUP_KEY = ON.

Ref.: index_option

The -> operator is used when we are working with a pointer and the dot is used otherwise. So if we have a struct class like:

struct class{ int num_students; int yr_grad; };

and we have an instance of a class* curr_class (class pointer), then to get access to number of students we would do

cout << curr_class->num_students << endl;

In case we had a simple class object , say class_2016, we would do

cout << class_2016.num_students << endl;

For the pointer to class the -> operator is equivalent to

(*obj).mem_var

Note: For a class, the way to access member functions of the class will also be the same way

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

• 0.5.0
• 0.5.9
• 0.6.0

For clarification, each pair is equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

For example,

package main

func main() {
    mymap := make(map[int]string)
    keys := make([]int, 0, len(mymap))
    for k := range mymap {
        keys = append(keys, k)
    }
}

To be efficient in Go, it's important to minimize memory allocations.

Bryan Denny's post above is not working for me since not all extensions have a "Content Type" sub-key in the registry. I had to tweak the code as follows:

private string GetMimeType(string sFileName)
{
  // Get file extension and if it is empty, return unknown
  string sExt = Path.GetExtension(sFileName);
  if (string.IsNullOrEmpty(sExt)) return "Unknown file type";

  // Default type is "EXT File"
  string mimeType = string.Format("{0} File", sExt.ToUpper().Replace(".", ""));

  // Open the registry key for the extension under HKEY_CLASSES_ROOT and return default if it doesn't exist
  Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(sExt);
  if (regKey == null) return mimeType;

  // Get the "(Default)" value and re-open the key for that value
  string sSubType = regKey.GetValue("").ToString();
  regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(sSubType);

  // If it exists, get the "(Default)" value of the new key
  if (regKey?.GetValue("") != null) mimeType = regKey.GetValue("").ToString();

  // Return the value
  return mimeType;
}

Now it works fine for me for all registered file types and un-registered or generic file types (like JPG, etc).

In my case, the route signature was different from the method parameter. I had id, but I was accepting documentId as parameter, that caused the problem.

[Route("Documents/{id}")]   <--- caused the webapi error
[Route("Documents/{documentId}")] <-- solved
public Document Get(string documentId)
{
  ..
}

You can add border to the UIImageView, and then change the size of the UIimageView according to the image size:

#import <QuartzCore/QuartzCore.h>


// adding border to the imageView
[imageView.layer setBorderColor: [[UIColor whiteColor] CGColor]];
[imageView.layer setBorderWidth: 2.0];

// resize the imageView to fit the image size
CGSize size = [image size];
float factor = size.width / self.frame.size.width;
if (factor < size.height / self.frame.size.height) {
    factor = size.height / self.frame.size.height;
}

CGRect rect = CGRectMake(0, 0, size.width/factor, size.height/factor);
imageView.frame = rect;

Make sure you to set the origin of the imageView to the center

if you open the psql console in a terminal window, by typing

$ psql

you're super user username will be shown before the =#, for example:

elisechant=#$

That will be the user name you should use for localhost.

Have a look at this picture: Graphical Projections

The glOrtho command produces an "Oblique" projection that you see in the bottom row. No matter how far away vertexes are in the z direction, they will not recede into the distance.

I use glOrtho every time I need to do 2D graphics in OpenGL (such as health bars, menus etc) using the following code every time the window is resized:

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, windowWidth, windowHeight, 0.0f, 0.0f, 1.0f);

This will remap the OpenGL coordinates into the equivalent pixel values (X going from 0 to windowWidth and Y going from 0 to windowHeight). Note that I've flipped the Y values because OpenGL coordinates start from the bottom left corner of the window. So by flipping, I get a more conventional (0,0) starting at the top left corner of the window rather.

Note that the Z values are clipped from 0 to 1. So be careful when you specify a Z value for your vertex's position, it will be clipped if it falls outside that range. Otherwise if it's inside that range, it will appear to have no effect on the position except for Z tests.

Linq.Min() / Linq.Max() approach:

DateTime date1 = new DateTime(2000,1,1);
DateTime date2 = new DateTime(2001,1,1);

DateTime minresult = new[] { date1,date2 }.Min();
DateTime maxresult = new[] { date1,date2 }.Max(); 

 ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext()); //getappcontext for just this activity context get
 File file = contextWrapper.getDir(file_path, Context.MODE_PRIVATE);  
 if (!isExternalStorageAvailable() || isExternalStorageReadOnly()) 
 { 
  saveToExternalStorage.setEnabled(false);
 }
 else
 {
  External_File = new File(getExternalFilesDir(file_path), file_name);//if ready then create a file for external 
 }

}
 try
  {
   FileInputStream fis = new FileInputStream(External_File);
   DataInputStream in = new DataInputStream(fis);
   BufferedReader br =new BufferedReader(new InputStreamReader(in));
   String strLine;
   while ((strLine = br.readLine()) != null) 
   {
    myData = myData + strLine;
   }
   in.close();
  }
  catch (IOException e) 
  {
   e.printStackTrace();
  }
  InputText.setText("Save data of External file::::  "+myData);


private static boolean isExternalStorageReadOnly() 
{ 
 String extStorageState = Environment.getExternalStorageState(); 
 if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(extStorageState))
 { 
  return true; 
 } 
 return false; 
} 

private static boolean isExternalStorageAvailable()
{ 
 String extStorageState = Environment.getExternalStorageState(); 
 if (Environment.MEDIA_MOUNTED.equals(extStorageState))
 { 
  return true; 
 } 
 return false; 
} 

Docker official position is explained in issue #11815 :

Issue 11815: Allow to specify default registries used in pull command

Resolution:

Like pointed out earlier (#11815), this would fragment the namespace, and hurt the community pretty badly, making dockerfiles no longer portable.

[the Maintainer] will close this for this reason.

Red Hat had a specific implementation that allowed it (see anwser, but it was refused by Docker upstream projet). It relied on --add-registry argument, which was set in /etc/containers/registries.conf on RHEL/CentOS 7.

EDIT:

Actually, Docker supports registry mirrors (also known as "Run a Registry as a pull-through cache"). https://docs.docker.com/registry/recipes/mirror/#configure-the-docker-daemon

Instead of %matplotlib inline,it is not a python script so we can write like this it will work from IPython import get_ipython get_ipython().run_line_magic('matplotlib', 'inline')

The solution Bobince posted works perfectly for me. I wanted to offer an alternative method as well for future visitors:

if (typeof(jQuery) == 'undefined') {
    (function() {
        var sct = document.createElement('script');
        sct.src = ('https:' == document.location.protocol ? 'https' : 'http') +
          '://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js';
        sct.type = 'text/javascript';
        sct.async = 'true';
        var domel = document.getElementsByTagName('script')[0];
        domel.parentNode.insertBefore(sct, domel);
    })();
}

In this example, I've included a conditional load for jQuery to demonstrate use case. Hope that's useful for someone!

Seconds with 2 decimal spaces:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime) / 1000000, "#,##0.00") & " seconds") 'end timer

Milliseconds:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime), "#,##0.00") & " milliseconds") 'end timer

Milliseconds with comma seperator:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime) * 1000, "#,##0.00") & " milliseconds") 'end timer

Just leaving this here for anyone that was looking for a simple timer formatted with seconds to 2 decimal spaces like I was. These are short and sweet little timers I like to use. They only take up one line of code at the beginning of the sub or function and one line of code again at the end. These aren't meant to be crazy accurate, I generally don't care about anything less then 1/100th of a second personally, but the milliseconds timer will give you the most accurate run time of these 3. I've also read you can get the incorrect read out if it happens to run while crossing over midnight, a rare instance but just FYI.

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

I think you are using it in wrong way. Here is an excerpt from the changelog:

New: @Url parameter annotation allows passing a complete URL for an endpoint.

So your interface should be like this:

public interface APIService {
    @GET
    Call<Users> getUsers(@Url String url);
}

You can't do it with client side script only... you could make an AJAX call to some server side code that will send an email...

Array type does not exist

There is no 'array' type in batch files, which is both an upside and a downside at times, but there are workarounds.

Here's a link that offers a few suggestions for creating a system for yourself similar to an array in a batch: http://hypftier.de/en/batch-tricks-arrays.

• As for echoing to a file echo variable >> filepath works for echoing the contents of a variable to a file,
• and echo. (the period is not a typo) works for echoing a newline character.

I think that these two together should work to accomplish what you need.

Further reading

• For an in depth explanation why "elem[1]" only LOOKS like an array see this SO answer: Arrays, linked lists and other data structures in cmd.exe (batch) script

I think :hover was missing in above answers. So following would do the needful.(if css was required)

#myDiv:hover
{
    cursor: pointer;
}

In Rails

If you need

• a "pretty printed" Hash
• in e.g. the Rails.logger
• that, specifically, runs inspect on the objects in the Hash
  • which is useful if you override/define the inspect method in your objects like you're supposed to

... then this works great! (And gets better, the bigger and more nested your Hash object is.)

logger.error my_hash.pretty_inspect

For example:

class MyObject1
  def inspect
    "<#{'*' * 10} My Object 1 #{'*' * 10}>"
  end
end

class MyObject2
  def inspect
    "<#{'*' * 10} My Object 2 #{'*' * 10}>"

my_hash = { a: 1, b: MyObject1.new, MyObject2.new => 3 }

Rails.logger.error my_hash
# {:a=>1, :b=><********** My Object 1 **********>, <********** My Object 2 **********>=>3}

# EW! ^

Rails.logger.error my_hash.pretty_inspect
# {:a=>1,
#  :b=><********** My Object 1 **********>,
#  <********** My Object 2 **********>=>3}

pretty_inspect comes from PrettyPrint, which rails includes by default. So, no gems needed and no conversion to JSON needed.

Not In Rails

If you're not in Rails or if the above fails for some reason, try using require "pp" first. For example:

require "pp"  # <-----------

class MyObject1
  def inspect
    "<#{'*' * 10} My Object 1 #{'*' * 10}>"
  end
end

class MyObject2
  def inspect
    "<#{'*' * 10} My Object 2 #{'*' * 10}>"
  end
end

my_hash = { a: 1, b: MyObject1.new, MyObject2.new => 3 }

puts my_hash
# {:a=>1, :b=><********** My Object 1 **********>, <********** My Object 2 **********>=>3}

# EW! ^

puts my_hash.pretty_inspect
# {:a=>1,
#  :b=><********** My Object 1 **********>,
#  <********** My Object 2 **********>=>3}

In your script, this part:

document.getElementById('Noite')

must be returning null and you are also attempting to set the display property to an invalid value. There are a couple of possible reasons for this first part to be null.

1. You are running the script too early before the document has been loaded and thus the Noite item can't be found.

2. There is no Noite item in your HTML.

I should point out that your use of document.write() in this case code probably signifies a problem. If the document has already loaded, then a new document.write() will clear the old content and start a new fresh document so no Noite item would be found.

If your document has not yet been loaded and thus you're doing document.write() inline to add HTML inline to the current document, then your document has not yet been fully loaded so that's probably why it can't find the Noite item.

The solution is probably to put this part of your script at the very end of your document so everything before it has already been loaded. So move this to the end of your body:

document.getElementById('Noite').style.display='block';

And, make sure that there are no document.write() statements in javascript after the document has been loaded (because they will clear the previous document and start a new one).

In addition, setting the display property to "display" doesn't make sense to me. The valid options for that are "block", "inline", "none", "table", etc... I'm not aware of any option named "display" for that style property. See here for valid options for teh display property.

You can see the fixed code work here in this demo: http://jsfiddle.net/jfriend00/yVJY4/. That jsFiddle is configured to have the javascript placed at the end of the document body so it runs after the document has been loaded.

P.S. I should point out that your lack of braces for your if statements and your inclusion of multiple statements on the same line makes your code very misleading and unclear.

I'm having a really hard time figuring out what you're asking, but here's a cleaned up version of your code that works which you can also see working here: http://jsfiddle.net/jfriend00/QCxwr/. Here's a list of the changes I made:

1. The script is located in the body, but after the content that it is referencing.
2. I've added var declarations to your variables (a good habit to always use).
3. The if statement was changed into an if/else which is a lot more efficient and more self-documenting as to what you're doing.
4. I've added braces for every if statement so it absolutely clear which statements are part of the if/else and which are not.
5. I've properly closed the </dd> tag you were inserting.
6. I've changed style.display = ''; to style.display = 'block';.
7. I've added semicolons at the end of every statement (another good habit to follow).

I often get this one when I accidentally call a function using the class name rather than the object name. This typically happens because i give them too similar names : P

ie:

MyClass myclass = new MyClass();

// then later

MyClass.someFunction();

This is obviously a static method. (good for somethings) But what i really wanted to do (in most cases was)

myclass.someFunction();

It's such a silly mistake, but every couple of months, i waste about 30 mins messing with vars in the "MyClass" definitions to work out what im doing wrong when really, its just a typo.

Funny note: stack overflow highlights the syntax to make the mistake really obvious here.

I faced the same issue ... little work around (only for implementation not anonymous objects ) ... we can declare the class level exception object as null ... then initialize it inside the catch block for run method ... if there was error in run method,this variable wont be null .. we can then have null check for this particular variable and if its not null then there was exception inside the thread execution.

class TestClass implements Runnable{
    private Exception ex;

        @Override
        public void run() {
            try{
                //business code
               }catch(Exception e){
                   ex=e;
               }
          }

      public void checkForException() throws Exception {
            if (ex!= null) {
                throw ex;
            }
        }
}     

call checkForException() after join()

constexpr indicates a value that's constant and known during compilation.
const indicates a value that's only constant; it's not compulsory to know during compilation.

int sz;
constexpr auto arraySize1 = sz;    // error! sz's value unknown at compilation
std::array<int, sz> data1;         // error! same problem

constexpr auto arraySize2 = 10;    // fine, 10 is a compile-time constant
std::array<int, arraySize2> data2; // fine, arraySize2 is constexpr

Note that const doesn’t offer the same guarantee as constexpr, because const objects need not be initialized with values known during compilation.

int sz;
const auto arraySize = sz;       // fine, arraySize is const copy of sz
std::array<int, arraySize> data; // error! arraySize's value unknown at compilation

All constexpr objects are const, but not all const objects are constexpr.

If you want compilers to guarantee that a variable has a value that can be used in contexts requiring compile-time constants, the tool to reach for is constexpr, not const.

First off, interpreted/compiled is not a property of the language but a property of the implementation. For most languages, most if not all implementations fall in one category, so one might save a few words saying the language is interpreted/compiled too, but it's still an important distinction, both because it aids understanding and because there are quite a few languages with usable implementations of both kinds (mostly in the realm of functional languages, see Haskell and ML). In addition, there are C interpreters and projects that attempt to compile a subset of Python to C or C++ code (and subsequently to machine code).

Second, compilation is not restricted to ahead-of-time compilation to native machine code. A compiler is, more generally, a program that converts a program in one programming language into a program in another programming language (arguably, you can even have a compiler with the same input and output language if significant transformations are applied). And JIT compilers compile to native machine code at runtime, which can give speed very close to or even better than ahead of time compilation (depending on the benchmark and the quality of the implementations compared).

But to stop nitpicking and answer the question you meant to ask: Practically (read: using a somewhat popular and mature implementation), Python is compiled. Not compiled to machine code ahead of time (i.e. "compiled" by the restricted and wrong, but alas common definition), "only" compiled to bytecode, but it's still compilation with at least some of the benefits. For example, the statement a = b.c() is compiled to a byte stream which, when "disassembled", looks somewhat like load 0 (b); load_str 'c'; get_attr; call_function 0; store 1 (a). This is a simplification, it's actually less readable and a bit more low-level - you can experiment with the standard library dis module and see what the real deal looks like. Interpreting this is faster than interpreting from a higher-level representation.

That bytecode is either interpreted (note that there's a difference, both in theory and in practical performance, between interpreting directly and first compiling to some intermediate representation and interpret that), as with the reference implementation (CPython), or both interpreted and compiled to optimized machine code at runtime, as with PyPy.

Odeds answer is almost complete. Just one thing to add.

1. Escape xml special chars like Emanuele Greco said.
2. Put the password in single quotes like Oded said
3. (this one is new) Escape single ticks with another single tick (ref)

having this password="'; this sould be a valid connection string:

connectionString='Server=dbsrv;User ID=myDbUser;Password='"&&;'

It is very important that AJAX requests retain session. The easiest example is when you try to do an AJAX request for the admin panel, let's say. Of course that you will protect the page that you make the request to, not to accessible by others who don't have the session you get after administrator login. Makes sense?

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

I was looking for "javascript prevent select change" on Google and this question comes at first result. At the end my solution was:

const $select = document.querySelector("#your_select_id");
let lastSelectedIndex = $select.selectedIndex;
// We save the last selected index on click
$select.addEventListener("click", function () {
    lastSelectedIndex = $select.selectedIndex;
});

// And then, in the change, we select it if the user does not confirm
$select.addEventListener("change", function (e) {
    if (!confirm("Some question or action")) {
        $select.selectedIndex = lastSelectedIndex;
        return;
    }
    // Here do whatever you want; the user has clicked "Yes" on the confirm
    // ...
});

I hope it helps to someone who is looking for this and does not have jQuery :)

Accepted Answer is correct, but it didn't fully work for me. I had to delete the package.lock file, re-run "npm install", and then close and reopen my visual studio. Hope this helps someone

Without seeing your full code, this is impossible to answer with any certainty. The error usually occurs when you are trying to unload a control rather than the form.

Make sure that you don't have the "me" in brackets.

Also if you can post the full code for the userform it would help massively.

To find duration or time interval with two different time zone

import org.joda.time.{DateTime, Period, PeriodType}

val s1 = "2019-06-13T05:50:00-07:00"
val s2 = "2019-10-09T11:30:00+09:00"    

val period = new Period(DateTime.parse(s1), DateTime.parse(s2), PeriodType dayTime())

period.getDays
period.getMinutes
period.getHours

output period = P117DT13H40M

days = 117
minutes = 40
hours = 13

Try this .{3,} this will match any characher except new line (\n)

I have passed this problem in VS2012. When I can't find "Browse with.." on the right-click of the project, I found it on File Menu -> Browse with. If it doesn't appear, first you have to click on menu bar, then try open file menu again. If it still doesn't appear, you can just go to Quick Launch on the top right of menu bar then type it "Browse with".

Firstly create app.js file in the directory you want to publish.

var http = require('http');
var fs = require('fs');
var mime = require('mime');
http.createServer(function(req,res){
    if (req.url != '/app.js') {
    var url = __dirname + req.url;
        fs.stat(url,function(err,stat){
            if (err) {
            res.writeHead(404,{'Content-Type':'text/html'});
            res.end('Your requested URI('+req.url+') wasn\'t found on our server');
            } else {
            var type = mime.getType(url);
            var fileSize = stat.size;
            var range = req.headers.range;
                if (range) {
                    var parts = range.replace(/bytes=/, "").split("-");
                var start = parseInt(parts[0], 10);
                    var end = parts[1] ? parseInt(parts[1], 10) : fileSize-1;
                    var chunksize = (end-start)+1;
                    var file = fs.createReadStream(url, {start, end});
                    var head = {
                'Content-Range': `bytes ${start}-${end}/${fileSize}`,
                'Accept-Ranges': 'bytes',
                'Content-Length': chunksize,
                'Content-Type': type
                }
                    res.writeHead(206, head);
                    file.pipe(res);
                    } else {    
                    var head = {
                'Content-Length': fileSize,
                'Content-Type': type
                    }
                res.writeHead(200, head);
                fs.createReadStream(url).pipe(res);
                    }
            }
        });
    } else {
    res.writeHead(403,{'Content-Type':'text/html'});
    res.end('Sorry, access to that file is Forbidden');
    }
}).listen(8080);

Simply run node app.js and your server shall be running on port 8080. Besides video it can stream all kinds of files.

What is “export default” in JavaScript?

In default export the naming of import is completely independent and we can use any name we like.

I will illustrate this line with a simple example.

Let’s say we have three modules and an index.html file:

• modul.js
• modul2.js
• modul3.js
• index.html

File modul.js

export function hello() {
    console.log("Modul: Saying hello!");
}

export let variable = 123;

File modul2.js

export function hello2() {
    console.log("Module2: Saying hello for the second time!");
}

export let variable2 = 456;

modul3.js

export default function hello3() {
    console.log("Module3: Saying hello for the third time!");
}

File index.html

<script type="module">
import * as mod from './modul.js';
import {hello2, variable2} from './modul2.js';
import blabla from './modul3.js'; // ! Here is the important stuff - we name the variable for the module as we like

mod.hello();
console.log("Module: " + mod.variable);

hello2();
console.log("Module2: " + variable2);

blabla();
</script>

The output is:

modul.js:2:10   -> Modul: Saying hello!
index.html:7:9  -> Module: 123
modul2.js:2:10  -> Module2: Saying hello for the second time!
index.html:10:9 -> Module2: 456
modul3.js:2:10  -> Module3: Saying hello for the third time!

So the longer explanation is:

'export default' is used if you want to export a single thing for a module.

So the thing that is important is "import blabla from './modul3.js'" - we could say instead:

"import pamelanderson from './modul3.js" and then pamelanderson();. This will work just fine when we use 'export default' and basically this is it - it allows us to name it whatever we like when it is default.

P.S.: If you want to test the example - create the files first, and then allow CORS in the browser -> if you are using Firefox type in the URL of the browser: about:config -> Search for "privacy.file_unique_origin" -> change it to "false" -> open index.html -> press F12 to open the console and see the output -> Enjoy and don't forget to return the CORS settings to default.

P.S.2: Sorry for the silly variable naming

More information is in link2medium and link2mdn.

This has happened to me also, after undating to IOS11 on my iPhone. When I try to connect to the corporate network it bring up the corporate cert and says it isn't trusted. I press the 'trust' button and the connection fails and the cert does not appear in the trusted certs list.

Try using @Html.DropDownList instead:

<td>Account: </td>
<td>@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))</td>

@Html.DropDownListFor expects a lambda as its first argument, not a string for the ID as you specify.

Other than that, without knowing what getUserAccounts() consists of, suffice to say it needs to return some sort of collection (IEnumerable for example) that has at least 1 object in it. If it returns null the property in the ViewBag won't have anything.

Thanks for the answer. I just got this working on Windows XP, with a few modifications. Here are my steps.

1. Download and install latest xampp to G:\xampp. As of 2010/03/12, this is 1.7.3.
2. Download the zip of xampp-win32-1.7.0.zip, which is the latest xampp distro without php 5.3. Extract somewhere, e.g. G:\xampp-win32-1.7.0\
3. Remove directory G:\xampp\php
4. Remove G:\xampp\apache\modules\php5apache2_2.dll and php5apache2_2_filter.dll
5. Copy G:\xampp-win32-1.7.0\xampp\php to G:\xampp\php.
6. Copy G:\xampp-win32-1.7.0\xampp\apache\bin\php* to G:\xampp\apache\bin
7. Edit G:\xampp\apache\conf\extra\httpd-xampp.conf.
   • Immediately after the line, <IfModule alias_module> add the lines

(snip)

<IfModule mime_module>
  LoadModule php5_module "/xampp/apache/bin/php5apache2_2.dll"
  AddType application/x-httpd-php-source .phps
  AddType application/x-httpd-php .php .php5 .php4 .php3 .phtml .phpt
    <Directory "/xampp/htdocs/xampp">
      <IfModule php5_module>
        <Files "status.php">
            php_admin_flag safe_mode off
        </Files>
      </IfModule>
    </Directory>
</IfModule>

(Note that this is taken from the same file in the 1.7.0 xampp distribution. If you run into trouble, check that conf file and make the new one match it.)

You should then be able to start the apache server with PHP 5.2.8. You can tail the G:\xampp\apache\logs\error.log file to see whether there are any errors on startup. If not, you should be able to see the XAMPP splash screen when you navigate to localhost.

Hope this helps the next guy.

cheers,

Another example using PowerShell for set permissions (File / Directory) :

Verify permissions

Get-Acl "C:\file.txt" | fl *

Apply full permissions for everyone

$acl = Get-Acl "C:\file.txt"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule("everyone","FullControl","Allow")
$acl.SetAccessRule($accessRule)
$acl | Set-Acl "C:\file.txt"

Hope this helps

To easily apply the comm command to unsorted files, use Bash's process substitution:

$ bash --version
GNU bash, version 3.2.51(1)-release
Copyright (C) 2007 Free Software Foundation, Inc.
$ cat > abc
123
567
132
$ cat > def
132
777
321

So the files abc and def have one line in common, the one with "132". Using comm on unsorted files:

$ comm abc def
123
    132
567
132
    777
    321
$ comm -12 abc def # No output! The common line is not found
$

The last line produced no output, the common line was not discovered.

Now use comm on sorted files, sorting the files with process substitution:

$ comm <( sort abc ) <( sort def )
123
            132
    321
567
    777
$ comm -12 <( sort abc ) <( sort def )
132

Now we got the 132 line!

Robustness diagrams are written after use cases and before class diagrams. They help to identify the roles of use case steps. You can use them to ensure your use cases are sufficiently robust to represent usage requirements for the system you're building.

They involve:

1. Actors
2. Use Cases
3. Entities
4. Boundaries
5. Controls

Whereas the Model-View-Controller pattern is used for user interfaces, the Entity-Control-Boundary Pattern (ECB) is used for systems. The following aspects of ECB can be likened to an abstract version of MVC, if that's helpful:

Entities (model)
Objects representing system data, often from the domain model.

Boundaries (view/service collaborator)
Objects that interface with system actors (e.g. a user or external service). Windows, screens and menus are examples of boundaries that interface with users.

Controls (controller)
Objects that mediate between boundaries and entities. These serve as the glue between boundary elements and entity elements, implementing the logic required to manage the various elements and their interactions. It is important to understand that you may decide to implement controllers within your design as something other than objects – many controllers are simple enough to be implemented as a method of an entity or boundary class for example.

Four rules apply to their communication:

1. Actors can only talk to boundary objects.
2. Boundary objects can only talk to controllers and actors.
3. Entity objects can only talk to controllers.
4. Controllers can talk to boundary objects and entity objects, and to other controllers, but not to actors

Communication allowed:

         Entity    Boundary   Control
Entity     X                     X
Boundary                         X
Control    X          X          X

I think you're confused about what binary is. Binary and decimal are just different representations of a number - e.g. 101 base 2 and 5 base 10 are the same number. The operations add, subtract, and compare operate on numbers - 101 base 2 == 5 base 10 and addition is the same logical operation no matter what base you're working in. The fact that your python interpreter may store things as binary internally doesn't affect how you work with it - if you have an integer type, just use +, -, etc.

If you have strings of binary digits, you'll have to either write your own implementation or convert them using the int(binaryString, 2) function.

Just adding the same code with the imports. Also contains the unimplemented code that is needed for compilation. I initially had trouble finding out what was imported for this code. Also adding the right package for the X509Certificate. Got this working with trial and error:

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import javax.security.cert.CertificateException;
import javax.security.cert.X509Certificate;
import javax.ws.rs.core.MultivaluedMap;

 TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {

     public java.security.cert.X509Certificate[] getAcceptedIssuers() {
         java.security.cert.X509Certificate[] chck = null;
         ;
         return chck;
     }

     public void checkServerTrusted(X509Certificate[] arg0, String arg1)
             throws CertificateException {
         // TODO Auto-generated method stub

     }

     public void checkClientTrusted(X509Certificate[] arg0, String arg1)
             throws CertificateException {

     }

     public void checkClientTrusted(
             java.security.cert.X509Certificate[] arg0, String arg1)
                     throws java.security.cert.CertificateException {
         // TODO Auto-generated method stub

     }

     public void checkServerTrusted(
             java.security.cert.X509Certificate[] arg0, String arg1)
                     throws java.security.cert.CertificateException {
         // TODO Auto-generated method stub

     }
 } };

 // Install the all-trusting trust manager
 try {
     SSLContext sc = SSLContext.getInstance("TLS");
     sc.init(null, trustAllCerts, new SecureRandom());
     HttpsURLConnection
     .setDefaultSSLSocketFactory(sc.getSocketFactory());
 } catch (Exception e) {
     ;
 }

Yes.

If you want to retrieve your value from an list box you should try this:

String itemSelected = numberListBox.GetItemText(numberListBox.SelectedItem);
