Programs & Examples On #Ncb

On a rather unrelated note: more performance hacks!

• [the first «conjecture» has been finally debunked by @ShreevatsaR; removed]

• When traversing the sequence, we can only get 3 possible cases in the 2-neighborhood of the current element N (shown first):

  1. [even] [odd]
  2. [odd] [even]
  3. [even] [even]

  To leap past these 2 elements means to compute (N >> 1) + N + 1, ((N << 1) + N + 1) >> 1 and N >> 2, respectively.

  Let`s prove that for both cases (1) and (2) it is possible to use the first formula, (N >> 1) + N + 1.

  Case (1) is obvious. Case (2) implies (N & 1) == 1, so if we assume (without loss of generality) that N is 2-bit long and its bits are ba from most- to least-significant, then a = 1, and the following holds:

  (N << 1) + N + 1:     (N >> 1) + N + 1:
  
          b10                    b1
           b1                     b
         +  1                   + 1
         ----                   ---
         bBb0                   bBb
  

  where B = !b. Right-shifting the first result gives us exactly what we want.

  Q.E.D.: (N & 1) == 1 ? (N >> 1) + N + 1 == ((N << 1) + N + 1) >> 1.

  As proven, we can traverse the sequence 2 elements at a time, using a single ternary operation. Another 2× time reduction.

The resulting algorithm looks like this:

uint64_t sequence(uint64_t size, uint64_t *path) {
    uint64_t n, i, c, maxi = 0, maxc = 0;

    for (n = i = (size - 1) | 1; i > 2; n = i -= 2) {
        c = 2;
        while ((n = ((n & 3)? (n >> 1) + n + 1 : (n >> 2))) > 2)
            c += 2;
        if (n == 2)
            c++;
        if (c > maxc) {
            maxi = i;
            maxc = c;
        }
    }
    *path = maxc;
    return maxi;
}

int main() {
    uint64_t maxi, maxc;

    maxi = sequence(1000000, &maxc);
    printf("%llu, %llu\n", maxi, maxc);
    return 0;
}

Here we compare n > 2 because the process may stop at 2 instead of 1 if the total length of the sequence is odd.

[EDIT:]

Let`s translate this into assembly!

MOV RCX, 1000000;



DEC RCX;
AND RCX, -2;
XOR RAX, RAX;
MOV RBX, RAX;

@main:
  XOR RSI, RSI;
  LEA RDI, [RCX + 1];

  @loop:
    ADD RSI, 2;
    LEA RDX, [RDI + RDI*2 + 2];
    SHR RDX, 1;
    SHRD RDI, RDI, 2;    ror rdi,2   would do the same thing
    CMOVL RDI, RDX;      Note that SHRD leaves OF = undefined with count>1, and this doesn't work on all CPUs.
    CMOVS RDI, RDX;
    CMP RDI, 2;
  JA @loop;

  LEA RDX, [RSI + 1];
  CMOVE RSI, RDX;

Use these commands to compile:

nasm -f elf64 file.asm
ld -o file file.o

See the C and an improved/bugfixed version of the asm by Peter Cordes on Godbolt. (editor's note: Sorry for putting my stuff in your answer, but my answer hit the 30k char limit from Godbolt links + text!)

You need to give a value to the constraints manually when using the new layout editor or the missing constraints can be added automatically by clicking the magic wand button in the toolbar menu of the design preview.

Permissions

You need the s3:GetObject permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 ("no such key") error.

If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 ("access denied") error.

The following operation is related to HeadObject:

GetObject

Source: https://docs.aws.amazon.com/AmazonS3/latest/API/API_HeadObject.html

this is how:

   /**
     * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
     * array containing the HTTP server response header fields and content.
     */
    function get_web_page( $url )
    {
        $user_agent='Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0';

        $options = array(

            CURLOPT_CUSTOMREQUEST  =>"GET",        //set request type post or get
            CURLOPT_POST           =>false,        //set to GET
            CURLOPT_USERAGENT      => $user_agent, //set user agent
            CURLOPT_COOKIEFILE     =>"cookie.txt", //set cookie file
            CURLOPT_COOKIEJAR      =>"cookie.txt", //set cookie jar
            CURLOPT_RETURNTRANSFER => true,     // return web page
            CURLOPT_HEADER         => false,    // don't return headers
            CURLOPT_FOLLOWLOCATION => true,     // follow redirects
            CURLOPT_ENCODING       => "",       // handle all encodings
            CURLOPT_AUTOREFERER    => true,     // set referer on redirect
            CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
            CURLOPT_TIMEOUT        => 120,      // timeout on response
            CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        );

        $ch      = curl_init( $url );
        curl_setopt_array( $ch, $options );
        $content = curl_exec( $ch );
        $err     = curl_errno( $ch );
        $errmsg  = curl_error( $ch );
        $header  = curl_getinfo( $ch );
        curl_close( $ch );

        $header['errno']   = $err;
        $header['errmsg']  = $errmsg;
        $header['content'] = $content;
        return $header;
    }

Example

//Read a web page and check for errors:

$result = get_web_page( $url );

if ( $result['errno'] != 0 )
    ... error: bad url, timeout, redirect loop ...

if ( $result['http_code'] != 200 )
    ... error: no page, no permissions, no service ...

$page = $result['content'];

We can pretend they are filenames and remove extensions:

tools::file_path_sans_ext(a)
# [1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"

I think that the fastest way to do this is to just clone the node, which will remove all event listeners:

var old_element = document.getElementById("btn");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);

Just be careful, as this will also clear event listeners on all child elements of the node in question, so if you want to preserve that you'll have to resort to explicitly removing listeners one at a time.

If this seems inconsistent from machine to machine, have you made sure that some 3rd party app like virus scan isn't intercepting something?

In addition to Ian's answer, I had to allow the font extensions in the request filtering module to make it work.

<system.webServer>
  <staticContent>
    <remove fileExtension=".woff" />
    <remove fileExtension=".woff2" />
    <mimeMap fileExtension=".woff" mimeType="application/x-font-woff" />
    <mimeMap fileExtension=".woff2" mimeType="application/x-font-woff" />
  </staticContent>
  <security>
      <requestFiltering>
          <fileExtensions>
              <add fileExtension=".woff" allowed="true" />
              <add fileExtension=".ttf" allowed="true" />
              <add fileExtension=".woff2" allowed="true" />
          </fileExtensions>
      </requestFiltering>
  </security>    
</system.webServer>

Use the valgrind option --track-origins=yes to have it track the origin of uninitialized values. This will make it slower and take more memory, but can be very helpful if you need to track down the origin of an uninitialized value.

Update: Regarding the point at which the uninitialized value is reported, the valgrind manual states:

It is important to understand that your program can copy around junk (uninitialised) data as much as it likes. Memcheck observes this and keeps track of the data, but does not complain. A complaint is issued only when your program attempts to make use of uninitialised data in a way that might affect your program's externally-visible behaviour.

From the Valgrind FAQ:

As for eager reporting of copies of uninitialised memory values, this has been suggested multiple times. Unfortunately, almost all programs legitimately copy uninitialised memory values around (because compilers pad structs to preserve alignment) and eager checking leads to hundreds of false positives. Therefore Memcheck does not support eager checking at this time.

const clone = (fn, context = this) => {
  // Creates a new function, optionally preserving desired context.
  const newFn = fn.bind(context);

  // Shallow copies over function properties, if any.
  return Object.assign(newFn, fn);
}

// Usage:

// Setup the function to copy from.
const log = (...args) => console.log(...args);
log.testProperty = 1;

// Clone and make sure the function and properties are intact.
const log2 = clone(log);
log2('foo');
// -> 'foo'
log2.testProperty;
// -> 1

// Make sure tweaks to the clone function's properties don't affect the original function properties.
log2.testProperty = 2;
log2.testProperty;
// -> 2
log.testProperty;
// -> 1

This clone function:

1. Preserves context.
2. Is a wrapper, and runs the original function.
3. Copies over function properties.

Note that this version only performs a shallow copy. If your function has objects as properties, the reference to the original object is preserved (same behavior as Object spread or Object.assign). This means that changing deep properties in the cloned function will affect the object referenced in the original function!

A little late to the party, but I think regular expressions are not the right tool for the job.

The problem is that you'll come across edge cases which would add extranous complexity to the regular expression. @est mentioned an example line:

for (int i = 0; i < 10; doSomethingTo("("));

This string literal contains an (unbalanced!) parenthesis, which breaks the logic. Apparently, you must ignore contents of string literals. In order to do this, you must take the double quotes into account. But string literals itself can contain double quotes. For instance, try this:

for (int i = 0; i < 10; doSomethingTo("\"(\\"));

If you address this using regular expressions, it'll add even more complexity to your pattern.

I think you are better off parsing the language. You could, for instance, use a language recognition tool like ANTLR. ANTLR is a parser generator tool, which can also generate a parser in Python. You must provide a grammar defining the target language, in your case C++. There are already numerous grammars for many languages out there, so you can just grab the C++ grammar.

Then you can easily walk the parser tree, searching for empty statements as while or for loop body.

For ISO 8601 format for Datetime & Datetime2, below is the recommendation from SQL Server. It does not support basic ISO 8601 format for datetime(yyyyMMddThhmmss).

DateTime

YYYY-MM-DDThh:mm:ss[.mmm]

YYYYMMDD[ hh:mm:ss[.mmm]]

Examples:

1. 2004-05-23T14:25:10

2. 2004-05-23T14:25:10.487

Datetime2

YYYY-MM-DDThh:mm:ss[.nnnnnnn]

YYYY-MM-DDThh:mm:ss[.nnnnnnn] Examples:

1. 2004-05-23T14:25:10

2. 2004-05-23T14:25:10.8849926

You can convert them using 126 option

--Datetime

DECLARE @table Table(ExtendedDate DATETIME, BasicDate Datetime)

DECLARE @ExtendedDate VARCHAR(30) = '2020-07-01T08:39:17' , @BasicDate VARCHAR(30) = '2009-01-23T10:53:21.000'

INSERT INTO @table(ExtendedDate, BasicDate)
SELECT convert(datetime,@ExtendedDate,126) ,convert(datetime,@BasicDate,126)

SELECT * FROM @table
go

-- Datetime2

DECLARE @table Table(ExtendedDate DATETIME2, BasicDate Datetime2)

DECLARE @ExtendedDate VARCHAR(30) = '2000-01-14T13:42:00.0000000' , @BasicDate VARCHAR(30) = '2009-01-23T10:53:21.0000000'

INSERT INTO @table(ExtendedDate, BasicDate)
SELECT convert(datetime2,@ExtendedDate,126) ,convert(datetime2,@BasicDate,126)

SELECT * FROM @table
go

Datetime

+-------------------------+-------------------------+
|      ExtendedDate       |        BasicDate        |

HTTP does not place a predefined limit on the length of each header field or on the length of the header section as a whole, as described in Section 2.5. Various ad hoc limitations on individual header field length are found in practice, often depending on the specific field semantics.

HTTP Header values are restricted by server implementations. Http specification doesn't restrict header size.

A server that receives a request header field, or set of fields, larger than it wishes to process MUST respond with an appropriate 4xx (Client Error) status code. Ignoring such header fields would increase the server's vulnerability to request smuggling attacks (Section 9.5).

Most servers will return 413 Entity Too Large or appropriate 4xx error when this happens.

A client MAY discard or truncate received header fields that are larger than the client wishes to process if the field semantics are such that the dropped value(s) can be safely ignored without changing the message framing or response semantics.

Uncapped HTTP header size keeps the server exposed to attacks and can bring down its capacity to serve organic traffic.

I implemeneted this algorithm in typescript and ES6

export type Coordinate = {
  lat: number;
  lon: number;
};

get the distance between two points:

function getDistanceBetweenTwoPoints(cord1: Coordinate, cord2: Coordinate) {
  if (cord1.lat == cord2.lat && cord1.lon == cord2.lon) {
    return 0;
  }

  const radlat1 = (Math.PI * cord1.lat) / 180;
  const radlat2 = (Math.PI * cord2.lat) / 180;

  const theta = cord1.lon - cord2.lon;
  const radtheta = (Math.PI * theta) / 180;

  let dist =
    Math.sin(radlat1) * Math.sin(radlat2) +
    Math.cos(radlat1) * Math.cos(radlat2) * Math.cos(radtheta);

  if (dist > 1) {
    dist = 1;
  }

  dist = Math.acos(dist);
  dist = (dist * 180) / Math.PI;
  dist = dist * 60 * 1.1515;
  dist = dist * 1.609344; //convert miles to km
  
  return dist;
}

get the distance between an array of coordinates

export function getTotalDistance(coordinates: Coordinate[]) {
  coordinates = coordinates.filter((cord) => {
    if (cord.lat && cord.lon) {
      return true;
    }
  });
  
  let totalDistance = 0;

  if (!coordinates) {
    return 0;
  }

  if (coordinates.length < 2) {
    return 0;
  }

  for (let i = 0; i < coordinates.length - 2; i++) {
    if (
      !coordinates[i].lon ||
      !coordinates[i].lat ||
      !coordinates[i + 1].lon ||
      !coordinates[i + 1].lat
    ) {
      totalDistance = totalDistance;
    }
    totalDistance =
      totalDistance +
      getDistanceBetweenTwoPoints(coordinates[i], coordinates[i + 1]);
  }

  return totalDistance.toFixed(2);
}

git status output tells you three things by default:

1. which branch you are on
2. What is the status of your local branch in relation to the remote branch
3. If you have any uncommitted files

When you did git commit , it committed to your local repository, thus #3 shows nothing to commit, however, #2 should show that you need to push or pull if you have setup the tracking branch.

If you find the output of git status verbose and difficult to comprehend, try using git status -sb this is less verbose and will show you clearly if you need to push or pull. In your case, the output would be something like:

master...origin/master [ahead 1]

git status is pretty useful, in the workflow you described do a git status -sb: after touching the file, after adding the file and after committing the file, see the difference in the output, it will give you more clarity on untracked, tracked and committed files.

Update #1
This answer is applicable if there was a misunderstanding in reading the git status output. However, as it was pointed out, in the OPs case, the upstream was not set correctly. For that, Chris Mae's answer is correct.

Disable swipe progmatically by-

    final View touchView = findViewById(R.id.Pager); 
    touchView.setOnTouchListener(new View.OnTouchListener() 
    {         
        @Override
        public boolean onTouch(View v, MotionEvent event)
        { 
           return true; 
        }
     });

and use this to swipe manually

touchView.setCurrentItem(int index);

target="_blank"

Opens a new window and show the related data.

target="_self"

Opens the window in the same frame, it means existing window itself.

target="_top"

Opens the linked document in the full body of the window.

target="_parent"

Opens data in the size of parent window.

 if($("element_selector").attr('disabled') || $("element_selector").prop('disabled'))
 {

    // code when element is disabled

  }

The folder containing your Anaconda installation contains a subfolder called conda-meta with json files for all installed packages, including one for Anaconda itself. Look for anaconda-<version>-<build>.json.

My file is called anaconda-5.0.1-py27hdb50712_1.json, and at the bottom is more info about the version:

"installed_by": "Anaconda2-5.0.1-Windows-x86_64.exe", 
"link": { "source": "C:\\ProgramData\\Anaconda2\\pkgs\\anaconda-5.0.1-py27hdb50712_1" }, 
"name": "anaconda", 
"platform": "win", 
"subdir": "win-64", 
"url": "https://repo.continuum.io/pkgs/main/win-64/anaconda-5.0.1-py27hdb50712_1.tar.bz2", 
"version": "5.0.1"

(Slightly edited for brevity.)

The output from conda -V is the conda version.

If you use dplyr package you can do:

library(dplyr)
filter(df, aged <= laclen)

My approach:

<div class="left">Left</div>
<div class="right">Right</div>

CSS:

.left {
    float: left;
    width: calc(100% - 200px);
    background: green;
}

.right {
    float: right;
    width: 200px;
    background: yellow;
}

I give here 2 ways of coping array, for C and C++ language. memcpy and copy both ar usable on C++ but copy is not usable for C, you have to use memcpy if you are trying to copy array in C.

#include <stdio.h>
#include <iostream>
#include <algorithm> // for using copy (library function)
#include <string.h> // for using memcpy (library function)


int main(){

    int arr[] = {1, 1, 2, 2, 3, 3};
    int brr[100];

    int len = sizeof(arr)/sizeof(*arr); // finding size of arr (array)

    std:: copy(arr, arr+len, brr); // which will work on C++ only (you have to use #include <algorithm>
    memcpy(brr, arr, len*(sizeof(int))); // which will work on both C and C++

    for(int i=0; i<len; i++){ // Printing brr (array).
        std:: cout << brr[i] << " ";
    }

    return 0;
}

If you just want to re-load/update dependencies (I assume, with constantly changing you mean either SNAPSHOTS or local dependencies you update yourself), you can use

mvn dependency:resolve

Very late to answer this, but worth to take a quick look at. Just 2 minutes needed to understand in detail.

First create this java program

import java.util.ArrayList;
import java.util.List;

public class GarbageCollectionAnalysisExample{
    public static void main(String[] args) {
           List<String> l = new ArrayList<String>();
           for (int i = 0; i < 100000000; i++) {
                  l = new ArrayList<String>(); //Memory leak
                  System.out.println(l);
           }
           System.out.println("Done");
    }
}

Use jps to find the vmid (virtual machine id i.e. JVM id)

Go to CMD and type below commands >

C:\>jps
18588 Jps
17252 GarbageCollectionAnalysisExample
16048
2084 Main

17252 is the vmid which we need.

Now we will learn how to use jmap and jhat

Use jmap - to generate heap dump

From java docs about jmap “jmap prints shared object memory maps or heap memory details of a given process or core file or a remote debug server”

Use following command to generate heap dump >

C:\>jmap -dump:file=E:\heapDump.jmap 17252
Dumping heap to E:\heapDump.jmap ...
Heap dump file created

Where 17252 is the vmid (picked from above).

Heap dump will be generated in E:\heapDump.jmap

Now use Jhat Jhat is used for analyzing the garbage collection dump in java -

C:\>jhat E:\heapDump.jmap
Reading from E:\heapDump.jmap...
Dump file created Mon Nov 07 23:59:19 IST 2016

By default, it will start http server on port 7000. Then we will go to http://localhost:7000/

Simple and precise (Source: Socket.IO google group):

socket.emit allows you to emit custom events on the server and client

socket.send sends messages which are received with the 'message' event

The first set of errors, for the missing vtable, are caused because you do not implement takeaway::textualGame(); instead you implement a non-member function, textualGame(). I think that adding the missing takeaway:: will fix that.

The cause of the last error is that you're calling a virtual function, initialData(), from the constructor of gameCore. At this stage, virtual functions are dispatched according to the type currently being constructed (gameCore), not the most derived class (takeaway). This particular function is pure virtual, and so calling it here gives undefined behaviour.

Two possible solutions:

• Move the initialisation code for gameCore out of the constructor and into a separate initialisation function, which must be called after the object is fully constructed; or
• Separate gameCore into two classes: an abstract interface to be implemented by takeaway, and a concrete class containing the state. Construct takeaway first, and then pass it (via a reference to the interface class) to the constructor of the concrete class.

I would recommend the second, as it is a move towards smaller classes and looser coupling, and it will be harder to use the classes incorrectly. The first is more error-prone, as there is no way be sure that the initialisation function is called correctly.

One final point: the destructor of a base class should usually either be virtual (to allow polymorphic deletion) or protected (to prevent invalid polymorphic deletion).

Partial classes recently helped with source control where multiple developers were adding to one file where new methods were added into the same part of the file (automated by Resharper).

These pushes to git caused merge conflicts. I found no way to tell the merge tool to take the new methods as a complete code block.

Partial classes in this respect allows for developers to stick to a version of their file, and we can merge them back in later by hand.

example -

• MainClass.cs - holds fields, constructor, etc
• MainClass1.cs - a developers new code as they implement
• MainClass2.cs - is another developers class for their new code.

You can try using the find function:

string str ("There are two needles in this haystack.");
string str2 ("needle");

if (str.find(str2) != string::npos) {
//.. found.
} 

I found a simple jQuery library called Sticky Table Headers. Two lines of code and it did exactly what I wanted. The solutions above don't manage the column widths, so if you have table cells that take up a lot of space, the resulting size of the persistent header will not match your table's width.

I come across similar problem while calling stored procedure

Which dynamically constructing the query for search I was calling above one by:

    {
        dbManager.ConnectionString = ConfigurationManager.ConnectionStrings["MSSQL"].ToString();
        DataSet ds = new DataSet();
        try
        {
            dbManager.Open();
            dbManager.CreateParameters(9);
            dbManager.AddParameters(0, "@AccessRightId", AccessRightId, ParameterDirection.Input);
            dbManager.AddParameters(1, "@RoleId", RoleId, ParameterDirection.Input);
            dbManager.AddParameters(2, "@ModuleId", ModuleId, ParameterDirection.Input);

that did the trick for Me.

I hope this will be helpfull to someone who fall in similar trap.

taking this one up a notch, for those of you who live on the edge.

gist: https://gist.github.com/akhoury/9118682 Demo: Code snippet below

Handlebars Helper: {{#xif EXPRESSION}} {{else}} {{/xif}}

a helper to execute an IF statement with any expression

1. EXPRESSION is a properly escaped String
2. Yes you NEED to properly escape the string literals or just alternate single and double quotes
3. you can access any global function or property i.e. encodeURIComponent(property)
4. this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), notice age is a string, just for so I can demo parseInt() later in this post

Usage:

<p>
 {{#xif " name == 'Sam' && age === '12' " }}
   BOOM
 {{else}}
   BAMM
 {{/xif}}
</p>

Output

<p>
  BOOM
</p>

JavaScript: (it depends on another helper- keep reading)

 Handlebars.registerHelper("xif", function (expression, options) {
    return Handlebars.helpers["x"].apply(this, [expression, options]) ? options.fn(this) : options.inverse(this);
  });

Handlebars Helper: {{x EXPRESSION}}

A helper to execute javascript expressions

1. EXPRESSION is a properly escaped String
2. Yes you NEED to properly escape the string literals or just alternate single and double quotes
3. you can access any global function or property i.e. parseInt(property)
4. this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), age is a string for demo purpose, it can be anything..

Usage:

<p>Url: {{x "'hi' + name + ', ' + window.location.href + ' <---- this is your href,' + ' your Age is:' + parseInt(this.age, 10)"}}</p>

Output:

<p>Url: hi Sam, http://example.com <---- this is your href, your Age is: 20</p>

Moar

if you want access upper level scope, this one is slightly different, the expression is the JOIN of all arguments, usage: say context data looks like this:

// data
{name: 'Sam', age: '20', address: { city: 'yomomaz' } }

// in template
// notice how the expression wrap all the string with quotes, and even the variables
// as they will become strings by the time they hit the helper
// play with it, you will immediately see the errored expressions and figure it out

{{#with address}}
    {{z '"hi " + "' ../this.name '" + " you live with " + "' city '"' }}
{{/with}}

Javascript:

Handlebars.registerHelper("z", function () {
    var options = arguments[arguments.length - 1]
    delete arguments[arguments.length - 1];
    return Handlebars.helpers["x"].apply(this, [Array.prototype.slice.call(arguments, 0).join(''), options]);
});

Handlebars.registerHelper("zif", function () {
    var options = arguments[arguments.length - 1]
    delete arguments[arguments.length - 1];
    return Handlebars.helpers["x"].apply(this, [Array.prototype.slice.call(arguments, 0).join(''), options]) ? options.fn(this) : options.inverse(this);
});

Given a file application.yaml in test/resources

From the test context, I can get the file with

String file = getClass().getClassLoader().getResource("application.yaml").getPath(); 

which will actually point to the file in test-classes

put this code to your php page.

$sql = "SELECT * FROM userdetail";
$result = mysqli_query("connection ", $sql);

while ($row = mysqli_fetch_array($result,MYSQLI_BOTH)) {
    echo "<img src='images/".$row['image']."'>";
    echo "<p>".$row['text']. "</p>";
}

i hope this is work.

JS Code:

function TodayDate(){
        let data= new Date();
        return data.getFullYear().toString()+'-' + (data.getMonth()+1).toString()+'-' + data.getDate().toString()

    document.getElementById('today').innerHTML = '<input type="date" name="Data" value="'+TodayDate()+'" ><br>';

Html Code:

A little bit rough but it works!

Today, in Office 365, Excel has so called 'array functions'. The filter function does exactly what you want. No need to use CTRL+SHIFT+ENTER anymore, a simple enter will suffice.

In Office 365, your problem would be simply solved by using:

=VLOOKUP(A3, FILTER(A2:C6, B2:B6="B"), 3, FALSE)

if($('#test2').is(':checked')) {
    $(this).append('stuff');
} 

In case you decide to use dangerous code that is subject to breakage, this extension function will fetch a key from a Dictionary<K,V> according to its internal indexing (which for Mono and .NET currently appears to be in the same order as you get by enumerating the Keys property).

It is much preferable to use Linq: dict.Keys.ElementAt(i), but that function will iterate O(N); the following is O(1) but with a reflection performance penalty.

using System;
using System.Collections.Generic;
using System.Reflection;

public static class Extensions
{
    public static TKey KeyByIndex<TKey,TValue>(this Dictionary<TKey, TValue> dict, int idx)
    {
        Type type = typeof(Dictionary<TKey, TValue>);
        FieldInfo info = type.GetField("entries", BindingFlags.NonPublic | BindingFlags.Instance);
        if (info != null)
        {
            // .NET
            Object element = ((Array)info.GetValue(dict)).GetValue(idx);
            return (TKey)element.GetType().GetField("key", BindingFlags.Public | BindingFlags.Instance).GetValue(element);
        }
        // Mono:
        info = type.GetField("keySlots", BindingFlags.NonPublic | BindingFlags.Instance);
        return (TKey)((Array)info.GetValue(dict)).GetValue(idx);
    }
};

What's the default superuser username/password for postgres after a new install?:

CAUTION The answer about changing the UNIX password for "postgres" through "$ sudo passwd postgres" is not preferred, and can even be DANGEROUS!

This is why: By default, the UNIX account "postgres" is locked, which means it cannot be logged in using a password. If you use "sudo passwd postgres", the account is immediately unlocked. Worse, if you set the password to something weak, like "postgres", then you are exposed to a great security danger. For example, there are a number of bots out there trying the username/password combo "postgres/postgres" to log into your UNIX system.

What you should do is follow Chris James's answer:

sudo -u postgres psql postgres

# \password postgres

Enter new password: 

To explain it a little bit...

SQL 2016 solution/workaround here (could also work in earlier versions). This may not work or be appropriate in every situation, but I resolved the error by granting my database user read/write schema ownership as follows in SSMS:

Database > Security > Users > User > Properties > Owned Schemas > check db_datareader and db_datawriter.

A caveat which the other answers don't seem to mention is that the time which is shown by dmesg doesn't take into account any sleep/suspend time. So there are cases where the usual answer of using dmesg -T doesn't work, and shows a completely wrong time.

A workaround for such situations is to write something to the kernel log at a known time and then use that entry as a reference to calculate the other times. Obviously, it will only work for times after the last suspend.

So to display the correct time for recent entries on machines which may have been suspended since their last boot, use something like this from my other answer here:

# write current time to kernel ring buffer so it appears in dmesg output
echo "timecheck: $(date +%s) = $(date +%F_%T)" | sudo tee /dev/kmsg

# use our "timecheck" entry to get the difference
# between the dmesg timestamp and real time
offset=$(dmesg | grep timecheck | tail -1 \
| perl -nle '($t1,$t2)=/^.(\d+)\S+ timecheck: (\d+)/; print $t2-$t1')

# pipe dmesg output through a Perl snippet to
# convert it's timestamp to correct readable times
dmesg | tail \
| perl -pe 'BEGIN{$offset=shift} s/^\[(\d+)\S+/localtime($1+$offset)/e' $offset

I do it using the following :-

package main

import (
    "fmt"
    "strings"
)

func main (){
    concatenation:= strings.Join([]string{"a","b","c"},"") //where second parameter is a separator. 
    fmt.Println(concatenation) //abc
}

Putting Maven aside, you can put JAR libraries inside the Main Jar but you will need to use your own classloader.

Use re.sub directly, this allows you to specify a count:

regex.sub('', url, 1)

(Note that the order of arguments is replacement, original not the opposite, as might be suspected.)

Maybe try this? It seems the problem is solved after remove all the handlers in my case.

for handler in logging.root.handlers[:]:

Along the lines of the accepted answer, if you have a JSON text sample you can plug it in to this converter, select your options and generate the C# code.

If you don't know the type at runtime, this topic looks like it would fit.

dynamically deserialize json into any object passed in. c#

As per the documentation, these are just synonyms. size() is there to be consistent with other STL containers (like vector, map, etc.) and length() is to be consistent with most peoples' intuitive notion of character strings. People usually talk about a word, sentence or paragraph's length, not its size, so length() is there to make things more readable.

While a bit more cryptic than join, you can also multiply the array by a string.

@arr * " "

Another way with lodash 4.17.2

_.chain(params)
    .keyBy('name')
    .mapValues('input')
    .value();

or

_.mapValues(_.keyBy(params, 'name'), 'input')

or with _.reduce

_.reduce(
    params,
    (acc, { name, input }) => ({ ...acc, [name]: input }),
    {}
)

SOLUTIONS

1. Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
2. Paste the following line in CMakeCache.txt: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

Note the path to g++ depends on OS. I have used my fedora path obtained using which g++

For those trying to calculate percentages with the accepted answer, but are losing precision:

If you run this:

echo "scale=2; (100/180) * 180" | bc

You get 99.00 only, which is losing precision.

If you run it this way:

echo "result = (100/180) * 180; scale=2; result / 1" | bc -l

Now you get 99.99.

Because you're scaling only at the moment of printing.

Refer to here

$('#graphtype option[value=""]').prop("selected", true);

This works well where #graphtype is the id of the select tag.

example select tag:

 <select name="site" id="site" class="form-control" onchange="getgraph1(this.options[this.selectedIndex].value);">
    <option value="" selected>Site</option> 
    <option value="sitea">SiteA</option>
    <option value="siteb">SiteB</option>
  </select>

Joking aside, if you're only expecting your input integer to be a zero or a one, you should really be checking that this is the case.

int yourInteger = whatever;
bool yourBool;
switch (yourInteger)
{
    case 0: yourBool = false; break;
    case 1: yourBool = true;  break;
    default:
        throw new InvalidOperationException("Integer value is not valid");
}

The out-of-the-box Convert won't check this; nor will yourInteger (==|!=) (0|1).

In addition to @delmadord's answer and your comments:

Currently there is no method to create subquery in FROM clause, so you need to manually use raw statement, then, if necessary, you will merge all the bindings:

$sub = Abc::where(..)->groupBy(..); // Eloquent Builder instance

$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )
    ->mergeBindings($sub->getQuery()) // you need to get underlying Query Builder
    ->count();

Mind that you need to merge bindings in correct order. If you have other bound clauses, you must put them after mergeBindings:

$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )

    // ->where(..) wrong

    ->mergeBindings($sub->getQuery()) // you need to get underlying Query Builder

    // ->where(..) correct

    ->count();

None of these attributes are reliable because per the servlet spec (2.4, 2.5 and 3.0), these attributes are overridden if you include/forward a second time (or if someone calls getNamedDispatcher). I think the only reliable way to get the original request URI/query string is to stick a filter at the beginning of your filter chain in web.xml that sets your own custom request attributes based on request.getRequestURI()/getQueryString() before any forwards/includes take place.

http://www.caucho.com/resin-3.0/webapp/faq.xtp contains an excellent summary of how this works (minus the technical note that a second forward/include messes up your ability to use these attributes).

If you want to concatenate the input, then replace printf("%s\n", buffer); with strcat(big_buffer, buffer);. Also create and initialize the big buffer at the beginning: char *big_buffer = new char[BIG_BUFFERSIZE]; big_buffer[0] = '\0';. You should also prevent a buffer overrun by verifying the current buffer length plus the new buffer length does not exceed the limit: if ((strlen(big_buffer) + strlen(buffer)) < BIG_BUFFERSIZE). The modified program would look like this:

#include <stdio.h>
#include <string.h>

#define BUFFERSIZE 10
#define BIG_BUFFERSIZE 1024

int main (int argc, char *argv[])
{
    char buffer[BUFFERSIZE];
    char *big_buffer = new char[BIG_BUFFERSIZE];
    big_buffer[0] = '\0';
    printf("Enter a message: \n");
    while(fgets(buffer, BUFFERSIZE , stdin) != NULL)
    {
        if ((strlen(big_buffer) + strlen(buffer)) < BIG_BUFFERSIZE)
        {
            strcat(big_buffer, buffer);
        }
    }
    return 0;
}

If you are passing all your parameters on the URL, then probably comma separated values would be the best choice. Then you would have an URL template like the following:

api.com/users?id=id1,id2,id3,id4,id5

You can use the $set syntax if you want to set the value of a document to an arbitrary value. This will either update the value if the attribute already exists on the document or create it if it doesn't. If you need to set a single value in a dictionary like you describe, you can use the dot notation to access child values.

If p is the object retrieved:

existing = p['d']['a']

For pymongo versions < 3.0

db.ProductData.update({
  '_id': p['_id']
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False, multi=False)

For pymongo versions >= 3.0

db.ProductData.update_one({
  '_id': p['_id']
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False)

However if you just need to increment the value, this approach could introduce issues when multiple requests could be running concurrently. Instead you should use the $inc syntax:

For pymongo versions < 3.0:

db.ProductData.update({
  '_id': p['_id']
},{
  '$inc': {
    'd.a': 1
  }
}, upsert=False, multi=False)

For pymongo versions >= 3.0:

db.ProductData.update_one({
  '_id': p['_id']
},{
  '$inc': {
    'd.a': 1
  }
}, upsert=False)

This ensures your increments will always happen.

You can copy subscribers dictionary object to a same type of temporary dictionary object and then iterate the temporary dictionary object using foreach loop.

You can overwrite Bootstraps default CSS by adding your own rules.

<style type="text/css">
   body { background: navy !important; } /* Adding !important forces the browser to overwrite the default style applied by Bootstrap */
</style>

Your problem can easily be solved by converting it to the object first. After it is converted to object, just use "astype" to convert it to str.

obj = lambda x:x[1:]
df['id']=df['id'].apply(obj).astype('str')

I think this is all you really need to do:

var listB = new List<int>{3, 4, 5};
var listA = new List<int>{1, 2, 3, 4, 5};

var listMerged = listA.Union(listB);

If it's open to a modification, you could use a suffix instead of a prefix. Then you could use tab-completion to get the original filename and add the suffix.

Otherwise, no this isn't something that is supported by the mv command. A simple shell script could cope though.

I just made sure that I am in the same directory as the json file and then simply ran this

curl -s -H "Content-Type: application/json" -XPOST localhost:9200/product/default/_bulk?pretty --data-binary @product.json

So if you too make sure you are at the same directory and run it this way. Note: product/default/ in the command is something specific to my environment. you can omit it or replace it with whatever is relevant to you.

Make it dataType instead of datatype.

And add below code in php as your ajax request is expecting json and will not accept anything, but json.

header('Content-Type: application/json');

Correct Content type for JSON and JSONP

The response visible in firebug is text data. Check Content-Type of the response header to verify, if the response is json. It should be application/json for dataType:'json' and text/html for dataType:'html'.

The answer I was searching for was answered here: How to use python argparse with args other than sys.argv?

If main.py and parse_args() is written in this way, then the parsing can be done nicely

# main.py
import argparse
def parse_args():
    parser = argparse.ArgumentParser(description="")
    parser.add_argument('--input', default='my_input.txt')
    return parser

def main(args):
    print(args.input)

if __name__ == "__main__":
    parser = parse_args()
    args = parser.parse_args()
    main(args)

Then you can call main() and parse arguments with parser.parse_args(['--input', 'foobar.txt']) to it in another python script:

# temp.py
from main import main, parse_args
parser = parse_args()
args = parser.parse_args([]) # note the square bracket
# to overwrite default, use parser.parse_args(['--input', 'foobar.txt'])
print(args) # Namespace(input='my_input.txt')
main(args)

Not an answer per se, but a guideline. Most of the time there is not much sense in declaring local T&& variable (as you did with std::vector<int>&& rval_ref). You will still have to std::move() them to use in foo(T&&) type methods. There is also the problem that was already mentioned that when you try to return such rval_ref from function you will get the standard reference-to-destroyed-temporary-fiasco.

Most of the time I would go with following pattern:

// Declarations
A a(B&&, C&&);
B b();
C c();

auto ret = a(b(), c());

You don't hold any refs to returned temporary objects, thus you avoid (inexperienced) programmer's error who wish to use a moved object.

auto bRet = b();
auto cRet = c();
auto aRet = a(std::move(b), std::move(c));

// Either these just fail (assert/exception), or you won't get 
// your expected results due to their clean state.
bRet.foo();
cRet.bar();

Obviously there are (although rather rare) cases where a function truly returns a T&& which is a reference to a non-temporary object that you can move into your object.

Regarding RVO: these mechanisms generally work and compiler can nicely avoid copying, but in cases where the return path is not obvious (exceptions, if conditionals determining the named object you will return, and probably couple others) rrefs are your saviors (even if potentially more expensive).

You can use this one: • You can type it by pressing Alt key and typing 0149.

For Xcode 4.3 the easier way might be: Edit/Refactor/Convert to objective-C ARC, then check off the files you don't want to be converted. I find this way the same as using the compiler flag above.

As Luiggi mentioned you need to change your main to:

import java.util.Arrays;

public class trial1{

    public static void main(String[] args){
        int[] A = numbers();
        System.out.println(Arrays.toString(A)); //Might require import of util.Arrays
    }

    public static int[] numbers(){
        int[] A = {1,2,3};
        return A;
    }
}

You may also want to make sure that your code localizes correctly, or make sure the users are used to the "international" notation. For example, "1,112" actually means different numbers across different countries. In Germany it means the number a little over one, instead of one thousand and something.

Corresponding Wikipedia article is at http://en.wikipedia.org/wiki/Decimal_mark. It seems to be poorly written at this time though. For example as a Chinese I'm not sure where does these description about thousand separator in China come from.

This should do it:

WHERE `date` = CURDATE() - INTERVAL 1 DAY

A Quick Hack Update

If you use the value none for all the CSS user-select properties (including browser prefixes of it), there is a problem which can be still occurred by this.

.div {
    -webkit-user-select: none; /* Chrome all / Safari all */
    -moz-user-select: none;    /* Firefox all             */
    -ms-user-select: none;     /* Internet Explorer  10+  */
     user-select: none;        /* Likely future           */
}

As CSS-Tricks says, the problem is:

WebKit still allows the text to be copied, if you select elements around it.

You can also use the below one to enforce that an entire element gets selected which means if you click on an element, all the text wrapped in that element will get selected. For this all you have to do is changing the value none to all.

.force-select {
    -webkit-user-select: all;  /* Chrome 49+     */
    -moz-user-select: all;     /* Firefox 43+    */
    -ms-user-select: all;      /* No support yet */
    user-select: all;          /* Likely future  */
}

It's a prefix to indicate the number is in hexadecimal rather than in some other base. The C programming language uses it to tell compiler.

Example:

0x6400 translates to 6*16^3 + 4*16^2 + 0*16^1 +0*16^0 = 25600. When compiler reads 0x6400, It understands the number is hexadecimal with the help of 0x term. Usually we can understand by (6400)₁₆ or (6400)₈ or whatever ..

For binary it would be:

0b00000001

Hope I have helped in some way.

Good day!

You can pass values by using the below .

@Html.ActionLink("About", "About", "Home",new { name = ViewBag.Name }, htmlAttributes:null )

Controller:

public ActionResult About(string name)
        {
            ViewBag.Message = "Your application description page.";
            ViewBag.NameTransfer = name;
            return View();
        }

And the URL looks like

http://localhost:50297/Home/About?name=My%20Name%20is%20Vijay

I don't think there is a more "angular way" to select an element. See, for instance, the way they are achieving this goal in the last example of this old documentation page:

{
     template: '<div>' +
    '<div class="title">{{title}}</div>' +
    '<div class="body" ng-transclude></div>' +
    '</div>',

    link: function(scope, element, attrs) {
        // Title element
        var title = angular.element(element.children()[0]),
        // ...
    }
}

The other answers did not help me as I only had client attached (the previous one that started the session was already detached).

To fix it I followed the answer here (I was not using xterm).

Which simply said:

1. Detach from tmux session
2. Run resize linux command
3. Reattach to tmux session

Start with deleting the file IISEXPRESS that exists in your directory, then start debugging.

If that does not solve the problem, go to your Project (Ctrl+Alt+L). Right click -> Properties -> Debug and Check "Enable Windows Authentication".

To do it the ASP.NET way:

<asp:TextBox ID="txtBox1" TextMode="Password" runat="server" />

Please try Firebug Lite for Google Chrome

String date = new SimpleDateFormat("dd-MM-yyyy").format(new Date());

Since the question was asked the Angular team has solved this issue by making it possible to dynamically create input names.

With Angular version 1.3 and later you can now do this:

<form name="vm.myForm" novalidate>
  <div ng-repeat="p in vm.persons">
    <input type="text" name="person_{{$index}}" ng-model="p" required>
    <span ng-show="vm.myForm['person_' + $index].$invalid">Enter a name</span>
  </div>
</form>

Demo

Angular 1.3 also introduced ngMessages, a more powerful tool for form validation. You can use the same technique with ngMessages:

<form name="vm.myFormNgMsg" novalidate>
    <div ng-repeat="p in vm.persons">
      <input type="text" name="person_{{$index}}" ng-model="p" required>
      <span ng-messages="vm.myFormNgMsg['person_' + $index].$error">
        <span ng-message="required">Enter a name</span>
      </span>
    </div>
  </form>

My solution reuses the one of amcdnl, but my fallback consist of using a height for the text container:

.my-caption h4 {
    display: -webkit-box;
    margin: 0 auto;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;
    overflow: hidden;
    text-overflow: ellipsis;

    height: 40px;/* Fallback for non-webkit */
}

You can try

$string = "this is the test for string." ;
$string = str_replace(' ', '_', $string);
$string = substr($string,0,10);

var_dump($string);

Output

this_is_th

Uncaught TypeError: undefined is not a function example_app.js:7

This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined.

So what's on example_app.js line 7? Looks like this:

var tasks = new ExampleApp.Collections.Tasks(data.tasks);

There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks is undefined.

So lets look at where that is declared:

var Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks. But you never add it to the ExampleApp.Collections object, a place you later expect it to be.

Change that to this, and I bet you'd be good.

ExampleApp.Collections.Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.

In Javascript, when you execute a function, it's evaluated like:

expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does

That expression can be complex. So when you see undefined is not a function it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.

And in this case, it was because you didn't put something where you thought you did.

compile is a configuration that is usually introduced by a plugin (most likely the java plugin) Have a look at the gradle userguide for details about configurations. For now adding the java plugin on top of your build script should do the trick:

apply plugin:'java'

If you are really looking to speed your code navigation, you might want to take a look at nWire for Java. It is a code exploration plugin for Eclipse. You can instantly see all the related artifacts. So, in that case, you will focus on the method call and instantly see all possible implementations, declarations, invocations, etc.

1. Open & Edit /etc/my.cnf or /etc/mysql/my.cnf, depending on your distro.
2. Add skip-grant-tables under [mysqld]
3. Restart Mysql
4. You should be able to login to mysql now using the below command mysql -u root -p
5. Run mysql> flush privileges;
6. Set new password by ALTER USER 'root'@'localhost' IDENTIFIED BY 'NewPassword';
7. Go back to /etc/my.cnf and remove/comment skip-grant-tables
8. Restart Mysql
9. Now you will be able to login with the new password mysql -u root -p

None from the answers above really addresses the issue correctly. The reason is that we want to disable selection of the cell but not necessarily of subviews inside the cell.

In my case I was presenting a UISwitch in the middle of the row and I wanted to disable selection for the rest of the row (which is empty) but not for the switch! The proper way of doing that is hence in the method

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

where a statement of the form

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];

disables selection for the specific cell while at the same time allows the user to manipulate the switch and hence use the appropriate selector. This is not true if somebody disables user interaction through the

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

method which merely prepares the cell and does not allow interaction with the UISwitch.

Moreover, using the method

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

in order to deselect the cell with a statement of the form

[tableView deselectRowAtIndexPath:indexPath animated:NO];

still shows the row being selected while the user presses on the original contentView of the cell.

Just my two cents. I am pretty sure many will find this useful.

You can use concat:

In [11]: pd.concat([df1['c'], df2['c']], axis=1, keys=['df1', 'df2'])
Out[11]: 
                 df1       df2
2014-01-01       NaN -0.978535
2014-01-02 -0.106510 -0.519239
2014-01-03 -0.846100 -0.313153
2014-01-04 -0.014253 -1.040702
2014-01-05  0.315156 -0.329967
2014-01-06 -0.510577 -0.940901
2014-01-07       NaN -0.024608
2014-01-08       NaN -1.791899

[8 rows x 2 columns]

The axis argument determines the way the DataFrames are stacked:

df1 = pd.DataFrame([1, 2, 3])
df2 = pd.DataFrame(['a', 'b', 'c'])

pd.concat([df1, df2], axis=0)
   0
0  1
1  2
2  3
0  a
1  b
2  c

pd.concat([df1, df2], axis=1)

   0  0
0  1  a
1  2  b
2  3  c

Use Sum()

 List<string> foo = new List<string>();
 foo.Add("1");
 foo.Add("2");
 foo.Add("3");
 foo.Add("4");

 Console.Write(foo.Sum(x => Convert.ToInt32(x)));

Prints:

If you have Gimp, I saw that exporting the image in .eps format would do the job.

Yes, the index starts at zero (0). The two arguments are startIndex and endIndex, where per the documentation:

The substring begins at the specified beginIndex and extends to the character at index endIndex - 1.

See here for more information.

public bool SaveBase64(string Dir, string FileName, string FileType, string Base64ImageString)
{
    try
    {
        string folder = System.Web.HttpContext.Current.Server.MapPath("~/") + Dir;
        if (!Directory.Exists(folder))
        {
            Directory.CreateDirectory(folder);
        }

        string filePath = folder + "/" + FileName + "." + FileType;
        File.WriteAllBytes(filePath, Convert.FromBase64String(Base64ImageString));
        return true;
    }
    catch
    {
        return false;

Assuming your RDBMS know window functions and CTE and USER_ID is the patient's id:

WITH TT AS (
    SELECT *, ROW_NUMBER() OVER(PARTITION BY USER_ID ORDER BY DOCUMENT_DATE DESC) AS N
    FROM test_table
)
SELECT *
FROM TT
WHERE N = 1;

I assumed you wanted to sort by DOCUMENT_DATE, you can easily change that if wanted. If your RDBMS doesn't know window functions, you'll have to do a join :

SELECT *
FROM test_table T1
INNER JOIN (SELECT USER_ID, MAX(DOCUMENT_DATE) AS maxDate
            FROM test_table
            GROUP BY USER_ID) T2
    ON T1.USER_ID = T2.USER_ID
        AND T1.DOCUMENT_DATE = T2.maxDate;

It would be good to tell us what your RDBMS is though. And this query selects the most recent date for every patient, you can add a condition for a given patient.

You just need to add this property in your asp:Button element (for example):

OnClientClick="javascript:window.close();"

It works perfectly.

from datetime import datetime, timedelta

yesterday = datetime.now() - timedelta(days=1)
yesterday.strftime('%m%d%y')

Not sure if this helps but in my app I had to check if a dictionary has changed.

Doing this will not work since basically it's still the same object:

val={'A':1,'B':2}
old_val=val

val['A']=10
if old_val != val:
  print('changed')

Using copy/deepcopy works:

import copy
val={'A':1,'B':2}
old_val=copy.deepcopy(val)

val['A']=10
if old_val != val:
  print('changed')

Since Qt 5.8, we now have QDateTime::currentSecsSinceEpoch() to deliver the seconds directly, a.k.a. as real Unix timestamp. So, no need to divide the result by 1000 to get seconds anymore.

Each compiler has its own libexec/ directory. Normally libexec directory contains small helper programs called by other programs. In this case, gcc is looking for its own 'cc1' compiler. Your machine may contains different versions of gcc, and each version should have its own 'cc1'. Normally these compilers are located on:

/usr/local/libexec/gcc/<architecture>/<compiler>/<compiler_version>/cc1

Similar path for g++. Above error means, that the current gcc version used is not able to find its own 'cc1' compiler. This normally points to a PATH issue.

You can also take a look at mechanize. Its meant to handle "stateful programmatic web browsing" (as per their site).

You need to convert your wildcard expression to a regular expression. For example:

    private bool WildcardMatch(String s, String wildcard, bool case_sensitive)
    {
        // Replace the * with an .* and the ? with a dot. Put ^ at the
        // beginning and a $ at the end
        String pattern = "^" + Regex.Escape(wildcard).Replace(@"\*", ".*").Replace(@"\?", ".") + "$";

        // Now, run the Regex as you already know
        Regex regex;
        if(case_sensitive)
            regex = new Regex(pattern);
        else
            regex = new Regex(pattern, RegexOptions.IgnoreCase);

        return(regex.IsMatch(s));
    } 

Delete Temp files by run > %temp%

And Open VS2015 by run as admin,

it works for me.

One way to do this would be to pass the instance of ParentClass to the ChildClass on construction

public ChildClass
{
    private ParentClass parent;

    public ChildClass(ParentClass parent)
    {
        this.parent = parent;
    }

    public void LoadData(DateTable dt)
    {
       // do something
       parent.CurrentRow++; // or whatever.
       parent.UpdateProgressBar(); // Call the method
    }
}

Make sure to pass the reference to this when constructing ChildClass inside parent:

if(loadData){

     ChildClass childClass = new ChildClass(this); // here

     childClass.LoadData(this.Datatable);

}

Caveat: This is probably not the best way to organise your classes, but it directly answers your question.

EDIT: In the comments you mention that more than 1 parent class wants to use ChildClass. This is possible with the introduction of an interface, eg:

public interface IParentClass
{
    void UpdateProgressBar();
    int CurrentRow{get; set;}
}

Now, make sure to implement that interface on both (all?) Parent Classes and change child class to this:

public ChildClass
{
    private IParentClass parent;

    public ChildClass(IParentClass parent)
    {
        this.parent = parent;
    }

    public void LoadData(DateTable dt)
    {
       // do something
       parent.CurrentRow++; // or whatever.
       parent.UpdateProgressBar(); // Call the method
    }
}

Now anything that implements IParentClass can construct an instance of ChildClass and pass this to its constructor.

Use the %02X format parameter:

printf("%02X",word[i]);

1. For API 11 and later, can use seekbar's XML attributes(android:rotation="270") for vertical effect.

   <SeekBar
   android:id="@+id/seekBar1"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:rotation="270"/>
   

2. For older API level (ex API10), only use Selva's answer:
   https://github.com/AndroSelva/Vertical-SeekBar-Android

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

Stack Overflow has solved a similar problem with long lines of code by using a DIV and having overflow-x:auto. CSS can't break up words for you.

You can do via Page directive.

For example:

<%@ page language="java" contentType="application/json; charset=UTF-8"
    pageEncoding="UTF-8"%>

• contentType="mimeType [ ;charset=characterSet ]" | "text/html;charset=ISO-8859-1"

The MIME type and character encoding the JSP file uses for the response it sends to the client. You can use any MIME type or character set that are valid for the JSP container. The default MIME type is text/html, and the default character set is ISO-8859-1.

Use the website mentioned in previous posts to create the icons:http://android-ui-utils.googlecode.com/hg/asset-studio/dist/index.html Unzip folder and Go into you file explorer on (windows or mac) find AndroidStudioProjects > "app name" > app > src > main (replace the web one here)> res (replace the rest with the one from the unzipped folder the you already downloaded)

*Close android studio so that you can make changes and when android studio is opened again the changes will appear

You can write DateTime? newdate = null;

in typeScript of angular 6, this code is working for me.

var formData = new FormData();
formData.append('name', 'value1');
formData.append('name', 'value2');
console.log(formData.get('name')); // this is return first element value.

or for all values:

console.log(formData.getAll('name')); // return all values

#1 I use the last one frequently when having buttons on the layout which are not generated (but static obviously).

If you use it in practice and in a business application, pay extra attention here, because when you use source obfuscater like ProGuard, you'll need to mark these methods in your activity as to not be obfuscated.

For archiving some kind of compile-time-security with this approach, have a look at Android Lint (example).

#2 Pros and cons for all methods are almost the same and the lesson should be:

Use what ever is most appropriate or feels most intuitive to you.

If you have to assign the same OnClickListener to multiple button instances, save it in the class-scope (#1). If you need a simple listener for a Button, make an anonymous implementation:

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // Take action.
    }
});

I tend to not implement the OnClickListener in the activity, this gets a little confusing from time to time (especially when you implement multiple other event-handlers and nobody knows what this is all doing).

input = {"A":"a", "B":"b", "C":"c"}
output = {k:v for (k,v) in input.items() if key_satifies_condition(k)}

If you use FluentNHibernate you can use following configuration code:

private ISessionFactory createSessionFactory()
{
    return Fluently.Configure()
            .Database(SQLiteConfiguration.Standard.UsingFileWithPassword(filename, password))
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<DBManager>())
            .ExposeConfiguration(this.buildSchema)
            .BuildSessionFactory();    
}

private void buildSchema(Configuration config)
{
        if (filename_not_exists == true)
        {
            new SchemaExport(config).Create(false, true);
        }
}    

Method UsingFileWithPassword(filename, password) encrypts a database file and sets password.
It runs only if the new database file is created. The old one not encrypted fails when is opened with this method.

Explanation in German but the code is a well-tested in-place implementation:

Private Sub QuickSort(ByRef Field() As String, ByVal LB As Long, ByVal UB As Long)
    Dim P1 As Long, P2 As Long, Ref As String, TEMP As String

    P1 = LB
    P2 = UB
    Ref = Field((P1 + P2) / 2)

    Do
        Do While (Field(P1) < Ref)
            P1 = P1 + 1
        Loop

        Do While (Field(P2) > Ref)
            P2 = P2 - 1
        Loop

        If P1 <= P2 Then
            TEMP = Field(P1)
            Field(P1) = Field(P2)
            Field(P2) = TEMP

            P1 = P1 + 1
            P2 = P2 - 1
        End If
    Loop Until (P1 > P2)

    If LB < P2 Then Call QuickSort(Field, LB, P2)
    If P1 < UB Then Call QuickSort(Field, P1, UB)
End Sub

Invoked like this:

Call QuickSort(MyArray, LBound(MyArray), UBound(MyArray))

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

The dynamic SQL is a different scope to the outer, calling SQL: so @siteid is not recognised

You'll have to use a temp table/table variable outside of the dynamic SQL:

DECLARE @dbName nvarchar(128) = 'myDb'
DECLARE @siteId TABLE (siteid int)

INSERT @siteId
exec ('SELECT TOP 1 Id FROM ' + @dbName + '..myTbl')  

select * FROM @siteId

Note: TOP without an ORDER BY is meaningless. There is no natural, implied or intrinsic ordering to a table. Any order is only guaranteed by the outermost ORDER BY

Warn/confirm User if Back button is Pressed is as below.

window.onbeforeunload = function() { return "Your work will be lost."; };

You can get more information using below mentioned links.

Disable Back Button in Browser using JavaScript

I hope this will help to you.

I found this much simpler. Simply type this into the terminal:

PATH=$PATH:C:\[pythondir]\scripts 

To me this is just one of many idiosyncracies (emphasis on the idio(t) ) of typescript that causes people to pull out their hair and curse the developers. Maybe they could work on coming up with more understandable error messages.

If you have directory listing disabled in your webserver, then the only way somebody will find it is by guessing or by finding a link to it.

That said, I've seen hacking scripts attempt to "guess" a whole bunch of these common names. "secret.html" would probably be in such a guess list.

The more reasonable solution is to restrict access using a username/password via a htaccess file (for apache) or the equivalent setting for whatever webserver you're using.

In my case git rm --cached didn't work. But i got it with a git rebase

On Windows use:

C:\PostgreSQL\pg10\bin>createuser -U postgres --pwprompt <USER>

Add --superuser or --createdb as appropriate.

See https://www.postgresql.org/docs/current/static/app-createuser.html for further options.

and I Have an issue which I wanted to do this sending data type in a Soft Button which I'd made and the softKey which is the default in every Android Device, so I've done this, first I've made an Intent in my "A" Activity:

            Intent intent = new Intent();
            intent.setClass(context, _AddNewEmployee.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
            startActivityForResult(intent, 6969);
            setResult(60);

Then in my second Activity, I've declared a Field in my "B" Activity:

private static int resultCode = 40;

then after I made my request successfully or whenever I wanted to tell the "A" Activity that this job is successfully done here change the value of resultCode to the same I've said in "A" Activity which in my case is "60" and then:

private void backToSearchActivityAndRequest() {
    Intent data = new Intent();
    data.putExtra("PhoneNumber", employeePhoneNumber);
    setResult(resultCode, data);
    finish();
}

@Override
public void onBackPressed() {
    backToSearchActivityAndRequest();
}

PS: Remember to remove the Super from the onBackPressed Method if you want this to work properly.

then I should call the onActivityResult Method in my "A" Activity as well:

   @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 6969 && resultCode == 60) {
            if (data != null) {
                    user_mobile = data.getStringExtra("PhoneNumber");
                    numberTextField.setText(user_mobile);
                    getEmployeeByNumber();
            }
        }
    }

that's it, hope it helps you out. #HappyCoding;

Usually if you use space as delimiter, you want to treat multiple spaces as one, because you parse the output of a command aligning some columns with spaces. (and the google search for that lead me here)

In this case a single cut command is not sufficient, and you need to use:

tr -s ' ' | cut -d ' ' -f 2

Or

awk '{print $2}'

You could use the String.IndexOf Method and pass StringComparison.OrdinalIgnoreCase as the type of search to use:

string title = "STRING";
bool contains = title.IndexOf("string", StringComparison.OrdinalIgnoreCase) >= 0;

Even better is defining a new extension method for string:

public static class StringExtensions
{
    public static bool Contains(this string source, string toCheck, StringComparison comp)
    {
        return source?.IndexOf(toCheck, comp) >= 0;
    }
}

Note, that null propagation ?. is available since C# 6.0 (VS 2015), for older versions use

if (source == null) return false;
return source.IndexOf(toCheck, comp) >= 0;

USAGE:

string title = "STRING";
bool contains = title.Contains("string", StringComparison.OrdinalIgnoreCase);

Something that your code doesn't account for is displaying multiple errors. As you have noted above it is possible for the user to upload a file >2MB of the wrong type, but your code can only report one of the issues. Try something like:

if(isset($_FILES['uploaded_file'])) {
    $errors     = array();
    $maxsize    = 2097152;
    $acceptable = array(
        'application/pdf',
        'image/jpeg',
        'image/jpg',
        'image/gif',
        'image/png'
    );

    if(($_FILES['uploaded_file']['size'] >= $maxsize) || ($_FILES["uploaded_file"]["size"] == 0)) {
        $errors[] = 'File too large. File must be less than 2 megabytes.';
    }

    if((!in_array($_FILES['uploaded_file']['type'], $acceptable)) && (!empty($_FILES["uploaded_file"]["type"]))) {
        $errors[] = 'Invalid file type. Only PDF, JPG, GIF and PNG types are accepted.';
    }

    if(count($errors) === 0) {
        move_uploaded_file($_FILES['uploaded_file']['tmpname'], '/store/to/location.file');
    } else {
        foreach($errors as $error) {
            echo '<script>alert("'.$error.'");</script>';
        }

        die(); //Ensure no more processing is done
    }
}

Look into the docs for move_uploaded_file() (it's called move not store) for more.

I had the same problem, and it came from a wrong client_id / Facebook App ID.

Did you switch your Facebook app to "public" or "online ? When you do so, Facebook creates a new app with a new App ID.

You can compare the "client_id" parameter value in the url with the one in your Facebook dashboard.

Also Make sure your app is public. Click on + Add product Now go to products => Facebook Login Now do the following:

Valid OAuth redirect URIs : example.com/

I just wanted to illustrate that the built-in solutions (SQL-only) are not always the best ones. At first I thought that because Django's QuerySet.objects.order_by method accepts multiple arguments, you could easily chain them:

ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]

But, it does not work as you would expect. Case in point, first is a list of presidents sorted by score (selecting top 5 for easier reading):

>>> auths = Author.objects.order_by('-score')[:5]
>>> for x in auths: print x
... 
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)

Using Alex Martelli's solution which accurately provides the top 5 people sorted by last_name:

>>> for x in sorted(auths, key=operator.attrgetter('last_name')): print x
... 
Benjamin Harrison (467)
James Monroe (487)
Gerald Rudolph (464)
Ulysses Simpson (474)
Harry Truman (471)

And now the combined order_by call:

>>> myauths = Author.objects.order_by('-score', 'last_name')[:5]
>>> for x in myauths: print x
... 
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)

As you can see it is the same result as the first one, meaning it doesn't work as you would expect.

Please not that, if you haven't installed git through Xcode or home-brew, you'll likely find the bash scripts haysclarks refers to in /Library/Developer/CommandLineTools/, and not in /Applications/Xcode.app/Contents/Developer/, thus making the lines to include within .bashrc the following:

    . /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

Try to use the <font> tag

?<table> 
    <thead> 
        <tr> 
            <th><font color="#FFF">Header 1</font></th> 
            <th><font color="#FFF">Header 1</font></th> 
            <th><font color="#FFF">Header 1</font></th> 
        </tr> 
    </thead> 
    <tbody> 
        <tr> 
            <td>blah blah</td> 
            <td>blah blah</td> 
            <td>blah blah</td> 
        </tr> 
    </tbody> 
</table>

But I think this should work, too:

?<table> 
    <thead> 
        <tr> 
            <th color="#FFF">Header 1</th> 
            <th color="#FFF">Header 1</th> 
            <th color="#FFF">Header 1</th> 
        </tr> 
    </thead> 
    <tbody> 
        <tr> 
            <td>blah blah</td> 
            <td>blah blah</td> 
            <td>blah blah</td> 
        </tr> 
    </tbody> 
</table>

EDIT:

Crossbrowser solution:

use capitals in HEX-color.

<th bgcolor="#5D7B9D" color="#FFFFFF"><font color="#FFFFFF">Header 1</font></th>

If you want to use glyph icons with bootstrap 2.3.2, Add the font files from bootstrap 3 to your project folder then copy this to your css file

 @font-face {
  font-family: 'Glyphicons Halflings';
  src: url('../fonts/glyphicons-halflings-regular.eot');
  src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

If

width = img.width;
height = img.height;
var ctx = canvas.getContext('2d');

Then you can use these transformations to turn the image to orientation 1

From orientation:

1. ctx.transform(1, 0, 0, 1, 0, 0);
2. ctx.transform(-1, 0, 0, 1, width, 0);
3. ctx.transform(-1, 0, 0, -1, width, height);
4. ctx.transform(1, 0, 0, -1, 0, height);
5. ctx.transform(0, 1, 1, 0, 0, 0);
6. ctx.transform(0, 1, -1, 0, height, 0);
7. ctx.transform(0, -1, -1, 0, height, width);
8. ctx.transform(0, -1, 1, 0, 0, width);

Before drawing the image on ctx

  lstResult.Clear();
  foreach (ManagementObject drive in new ManagementObjectSearcher("select * from Win32_DiskDrive where InterfaceType='USB'").Get())
  {
       foreach (ManagementObject partition in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskDrive.DeviceID='" + drive["DeviceID"] + "'} WHERE AssocClass = Win32_DiskDriveToDiskPartition").Get())
       {
            foreach (ManagementObject disk in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" + partition["DeviceID"] + "'} WHERE AssocClass = Win32_LogicalDiskToPartition").Get())
            {
                  foreach (var item in disk.Properties)
                  {
                       object value = disk.GetPropertyValue(item.Name);
                  }
                  string valor = disk["Name"].ToString();
                  lstResult.Add(valor);
                  }
             }
        }
   }

When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

For more : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

In another way,

If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”

There won't be any "merge commit" in fast-forwarding merge.

Using Date pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z' and Java 8 you could do

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);

Update: For pre 26 use Joda time

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
LocalDate date = org.joda.time.LocalDate.parse(string, formatter);

In app/build.gradle file, add like this-

dependencies {    
    compile 'joda-time:joda-time:2.9.4'
}

Update on 11 December 2015

Username + password is no longer a recommended solution. This is due to

I tried this and Gmail sent the email used as username in this code an email saying that We recently blocked a sign-in attempt to your Google Account, and directed me to this support page: support.google.com/accounts/answer/6010255 so it looks for it to work, the email account being used to send needs to reduce their own security

Google had released Gmail API - https://developers.google.com/gmail/api/?hl=en. We should use oAuth2 method, instead of username + password.

Here's the code snippet to work with Gmail API.

GoogleMail.java

import com.google.api.client.util.Base64;
import com.google.api.services.gmail.Gmail;

import javax.mail.MessagingException;

import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

/**

public class GoogleMail {
    private GoogleMail() {
    }

    private static MimeMessage createEmail(String to, String cc, String from, String subject, String bodyText) throws MessagingException {
        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);

        MimeMessage email = new MimeMessage(session);
        InternetAddress tAddress = new InternetAddress(to);
        InternetAddress cAddress = cc.isEmpty() ? null : new InternetAddress(cc);
        InternetAddress fAddress = new InternetAddress(from);

        email.setFrom(fAddress);
        if (cAddress != null) {
            email.addRecipient(javax.mail.Message.RecipientType.CC, cAddress);
        }
        email.addRecipient(javax.mail.Message.RecipientType.TO, tAddress);
        email.setSubject(subject);
        email.setText(bodyText);
        return email;
    }

    private static Message createMessageWithEmail(MimeMessage email) throws MessagingException, IOException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        email.writeTo(baos);
        String encodedEmail = Base64.encodeBase64URLSafeString(baos.toByteArray());
        Message message = new Message();
        message.setRaw(encodedEmail);
        return message;
    }

    public static void Send(Gmail service, String recipientEmail, String ccEmail, String fromEmail, String title, String message) throws IOException, MessagingException {
        Message m = createMessageWithEmail(createEmail(recipientEmail, ccEmail, fromEmail, title, message));
        service.users().messages().send("me", m).execute();
    }
}

To construct an authorized Gmail service through oAuth2, here's the code snippet.

To provide a user friendly way of oAuth2 authentication, I made use of JavaFX, to display the following input dialog

The key to display user friendly oAuth2 dialog can be found in MyAuthorizationCodeInstalledApp.java and SimpleSwingBrowser.java

document.getElementById("my").className = 'myclass';

Try setting the parameters' "default value" to use the same query as the "available values". In effect it provides every single "available value" as a "default value" and the "Select All" option is automatically checked.

out.write(c.toString());
out.newLine();

here is a simple solution, I hope it works

EDIT: I was using "\n" which was obviously not recommended approach, modified answer.

v-bind and v-on are two frequently used directives in vuejs html template. So they provided a shorthand notation for the both of them as follows:

You can replace v-on: with @

v-on:click='someFunction'

as:

@click='someFunction'

Another example:

v-on:keyup='someKeyUpFunction'

as:

@keyup='someKeyUpFunction'

Similarly, v-bind with :

v-bind:href='var1'

Can be written as:

:href='var1'

Hope it helps!

I've been using Jasob for years and it is hands down the best obfuscator out there.
It has an advanced UI but is still intuitive and easy to use.
It will also handle HTML and CSS files.

The best way to use it is to prefix all of your private variables with something like an underscore, then use the sort feature to group them all together and check them off as targets for obfuscation.

Users can still view your source, but it's much more difficult to decipher when your private variables are converted from something like _sUserPreferredNickName to a.

The engine will automatically tally up the number of targeted variables and prioritize them to get the maximum compression.

I don't work for Jasob and I get nothing out of promoting them, just offering some friendly advice.
The downside is that it's not free and is a little pricey, but still worth it when stacked against alternatives - the 'free' options don't even come close.

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

Based on l2aelba anwser. This was tested on FF, Safari, Chrome, IE (8,9,10 and 11)

    $("#editText").on("paste", function (e) {
        e.preventDefault();

        var text;
        var clp = (e.originalEvent || e).clipboardData;
        if (clp === undefined || clp === null) {
            text = window.clipboardData.getData("text") || "";
            if (text !== "") {
                if (window.getSelection) {
                    var newNode = document.createElement("span");
                    newNode.innerHTML = text;
                    window.getSelection().getRangeAt(0).insertNode(newNode);
                } else {
                    document.selection.createRange().pasteHTML(text);
                }
            }
        } else {
            text = clp.getData('text/plain') || "";
            if (text !== "") {
                document.execCommand('insertText', false, text);
            }
        }
    });

You can do the same like this:

@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    FaqQuestions faqQuestions = null;
    try {
        faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
                questionId);
        Hibernate.initialize(faqQuestions.getFaqAnswers());

        tx.commit();
        faqQuestions.getFaqAnswers().size();
    } finally {
        session.close();
    }
    return faqQuestions;
}

Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

Here is my solution

-- Create the maximum number of words we want to pick (indexes in n)
with recursive n(i) as (
    select
        1 i
    union all
    select i+1 from n where i < 1000
)
select distinct
    s.id,
    s.oaddress,
    -- n.i,
    -- use the index to pick the nth word, the last words will always repeat. Remove the duplicates with distinct
    if(instr(reverse(trim(substring_index(s.oaddress,' ',n.i))),' ') > 0,
        reverse(substr(reverse(trim(substring_index(s.oaddress,' ',n.i))),1,
            instr(reverse(trim(substring_index(s.oaddress,' ',n.i))),' '))),
        trim(substring_index(s.oaddress,' ',n.i))) oth
from 
    app_schools s,
    n

The best way is to add the directory to the load path and then require the basename of each file. This is because you want to avoid accidentally requiring the same file twice -- often not the intended behavior. Whether a file will be loaded or not is dependent on whether require has seen the path passed to it before. For example, this simple irb session shows that you can mistakenly require and load the same file twice.

$ irb
irb(main):001:0> require 'test'
=> true
irb(main):002:0> require './test'
=> true
irb(main):003:0> require './test.rb'
=> false
irb(main):004:0> require 'test'
=> false

Note that the first two lines return true meaning the same file was loaded both times. When paths are used, even if the paths point to the same location, require doesn't know that the file was already required.

Here instead, we add a directory to the load path and then require the basename of each *.rb file within.

dir = "/path/to/directory"
$LOAD_PATH.unshift(dir)
Dir[File.join(dir, "*.rb")].each {|file| require File.basename(file) }

If you don't care about the file being required more than once, or your intention is just to load the contents of the file, perhaps load should be used instead of require. Use load in this case, because it better expresses what you're trying to accomplish. For example:

Dir["/path/to/directory/*.rb"].each {|file| load file }

Hide the input with css, add a label and assign it to input button. label will be clickable and when clicked, it will fire up the file dialog.

<input type="file" id="files" class="hidden"/>
<label for="files">Select file</label>

Then style the label as a button if you want.

It is because the Creation was delayed. If you want the picture to be loaded immediately, you can simply add this code into the init phase.

src.CacheOption = BitmapCacheOption.OnLoad;

like this:

src.BeginInit();
src.UriSource = new Uri("picture.jpg", UriKind.Relative);
src.CacheOption = BitmapCacheOption.OnLoad;
src.EndInit();

When a and b are 1-dimensional sequences, numpy.cov(a,b)[0][1] is equivalent to your cov(a,b).

The 2x2 array returned by np.cov(a,b) has elements equal to

cov(a,a)  cov(a,b)

cov(a,b)  cov(b,b)

(where, again, cov is the function you defined above.)

The simplest way, based on @nosklo's comment and answer:

import tempfile
tmp = tempfile.mkdtemp()

But if you want to manually control the creation of the directories:

import os
from tempfile import gettempdir
tmp = os.path.join(gettempdir(), '.{}'.format(hash(os.times())))
os.makedirs(tmp)

That way you can easily clean up after yourself when you are done (for privacy, resources, security, whatever) with:

from shutil import rmtree
rmtree(tmp, ignore_errors=True)

This is similar to what applications like Google Chrome and Linux systemd do. They just use a shorter hex hash and an app-specific prefix to "advertise" their presence.

The obj directory is for intermediate object files and other transient data files that are generated by the compiler or build system during a build. The bin directory is the directory that final output binaries (and any dependencies or other deployable files) will be written to.

You can change the actual directories used for both purposes within the project settings, if you like.

If you have a colleague working with you:

1) ask him to rename the file causing problems and commit

2) you update (now you see the file with invalid checksum with different name)

3) rename it back to its original name

4) commit (and ask you colleague to update to get back the file name in its initial state)

This solved the problem for me.

We can three part naming like database_name..object_name

The below query will create the table into our database(with out constraints)

SELECT * 
INTO DestinationDB..MyDestinationTable 
FROM SourceDB..MySourceTable 

Alternatively you could:

INSERT INTO DestinationDB..MyDestinationTable 
SELECT * FROM SourceDB..MySourceTable

If your destination table exists and is empty.

use ondragstart(event) instead of ondrag(event)

Make sure that when you cloned the repository, you did so with the SSH URL and not the HTTPS; in the clone URL box of the repo, choose the SSH protocol before copying the URL. See image below:

I'm setting up a dev server to play with that mirrors our outdated live one, I used The Perfect Server - Ubuntu 14.04 (nginx, BIND, MySQL, PHP, Postfix, Dovecot and ISPConfig 3)

After experiencing the same issue, I came across this post and nothing was working. I changed the value in every recommended file (nginx.conf, ispconfig.vhost, /sites-available/default, etc.)

Finally, changing client_max_body_size in my /etc/nginx/sites-available/apps.vhost and restarting nginx is what did the trick. Hopefully it helps someone else.

I got the same issue. And I add 2 framework I need to Build Phases. Hope this help!

Make sure you have the access to the directory you are trying to spool. I tried to spool to root and it did not created the file (e.g c:\test.txt). You can check where you are spooling by issuing spool command.

Another way is to use direnv and to separate config files per directory. For example:

.
+-- companyA
¦  +-- .envrc
¦  +-- .gitconfig
+-- companyB
¦  +-- .envrc
¦  +-- .gitconfig
+-- personal
   +-- .envrc
   +-- .gitconfig

Each .envrc should contain something like this:

export GIT_CONFIG=$(pwd)/.gitconfig

And .gitconfig is usual gitconfig with desired values.

Here's a simple function that creates a CSS color string from RGB values ranging from 0 to 255:

function rgb(r, g, b){
  return "rgb("+r+","+g+","+b+")";
}

Alternatively (to create fewer string objects), you could use array join():

function rgb(r, g, b){
  return ["rgb(",r,",",g,",",b,")"].join("");
}

The above functions will only work properly if (r, g, and b) are integers between 0 and 255. If they are not integers, the color system will treat them as in the range from 0 to 1. To account for non-integer numbers, use the following:

function rgb(r, g, b){
  r = Math.floor(r);
  g = Math.floor(g);
  b = Math.floor(b);
  return ["rgb(",r,",",g,",",b,")"].join("");
}

You could also use ES6 language features:

const rgb = (r, g, b) => 
  `rgb(${Math.floor(r)},${Math.floor(g)},${Math.floor(b)})`;

Even I had the same problem understanding how are CPython, JPython, IronPython, PyPy are different from each other.

So, I am willing to clear three things before I begin to explain:

1. Python: It is a language, it only states/describes how to convey/express yourself to the interpreter (the program which accepts your python code).
2. Implementation: It is all about how the interpreter was written, specifically, in what language and what it ends up doing.
3. Bytecode: It is the code that is processed by a program, usually referred to as a virtual machine, rather than by the "real" computer machine, the hardware processor.

CPython is the implementation, which was written in C language. It ends up producing bytecode (stack-machine based instruction set) which is Python specific and then executes it. The reason to convert Python code to a bytecode is because it's easier to implement an interpreter if it looks like machine instructions. But, it isn't necessary to produce some bytecode prior to execution of the Python code (but CPython does produce).

If you want to look at CPython's bytecode then you can. Here's how you can:

>>> def f(x, y):                # line 1
...    print("Hello")           # line 2
...    if x:                    # line 3
...       y += x                # line 4
...    print(x, y)              # line 5
...    return x+y               # line 6
...                             # line 7
>>> import dis                  # line 8
>>> dis.dis(f)                  # line 9
  2           0 LOAD_GLOBAL              0 (print)

Now, let's have a look at the above code. Lines 1 to 6 are a function definition. In line 8, we import the 'dis' module which can be used to view the intermediate Python bytecode (or you can say, disassembler for Python bytecode) that is generated by CPython (interpreter).

NOTE: I got the link to this code from #python IRC channel: https://gist.github.com/nedbat/e89fa710db0edfb9057dc8d18d979f9c

And then, there is Jython, which is written in Java and ends up producing Java byte code. The Java byte code runs on Java Runtime Environment, which is an implementation of Java Virtual Machine (JVM). If this is confusing then I suspect that you have no clue how Java works. In layman terms, Java (the language, not the compiler) code is taken by the Java compiler and outputs a file (which is Java byte code) that can be run only using a JRE. This is done so that, once the Java code is compiled then it can be ported to other machines in Java byte code format, which can be only run by JRE. If this is still confusing then you may want to have a look at this web page.

Here, you may ask if the CPython's bytecode is portable like Jython, I suspect not. The bytecode produced in CPython implementation was specific to that interpreter for making it easy for further execution of code (I also suspect that, such intermediate bytecode production, just for the ease the of processing is done in many other interpreters).

So, in Jython, when you compile your Python code, you end up with Java byte code, which can be run on a JVM.

Similarly, IronPython (written in C# language) compiles down your Python code to Common Language Runtime (CLR), which is a similar technology as compared to JVM, developed by Microsoft.

I was solving this algorithm and get stuck with the pairs part.

This explanation help me a lot https://betterexplained.com/articles/techniques-for-adding-the-numbers-1-to-100/

So to calculate the sum of series of numbers:

n(n+1)/2

But you need to calculate this

1 + 2 + ... + (n-1)

So in order to get this you can use

n(n+1)/2 - n

that is equal to

n(n-1)/2

This does not answer the original question, but as the question is highly ranked and linked for any ContextClassLoader query, I think it is important to answer the related question of when the context class loader should be used. Short answer: never use the context class loader! But set it to getClass().getClassLoader() when you have to call a method that is missing a ClassLoader parameter.

When code from one class asks to load another class, the correct class loader to use is the same class loader as the caller class (i.e., getClass().getClassLoader()). This is the way things work 99.9% of the time because this is what the JVM does itself the first time you construct an instance of a new class, invoke a static method, or access a static field.

When you want to create a class using reflection (such as when deserializing or loading a configurable named class), the library that does the reflection should always ask the application which class loader to use, by receiving the ClassLoader as a parameter from the application. The application (which knows all the classes that need constructing) should pass it getClass().getClassLoader().

Any other way to obtain a class loader is incorrect. If a library uses hacks such as Thread.getContextClassLoader(), sun.misc.VM.latestUserDefinedLoader(), or sun.reflect.Reflection.getCallerClass() it is a bug caused by a deficiency in the API. Basically, Thread.getContextClassLoader() exists only because whoever designed the ObjectInputStream API forgot to accept the ClassLoader as a parameter, and this mistake has haunted the Java community to this day.

That said, many many JDK classes use one of a few hacks to guess some class loader to use. Some use the ContextClassLoader (which fails when you run different apps on a shared thread pool, or when you leave the ContextClassLoader null), some walk the stack (which fails when the direct caller of the class is itself a library), some use the system class loader (which is fine, as long as it is documented to only use classes in the CLASSPATH) or bootstrap class loader, and some use an unpredictable combination of the above techniques (which only makes things more confusing). This has resulted in much weeping and gnashing of teeth.

When using such an API, first, try to find an overload of the method that accepts the class loader as a parameter. If there is no sensible method, then try setting the ContextClassLoader before the API call (and resetting it afterwards):

ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
try {
    Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
    // call some API that uses reflection without taking ClassLoader param
} finally {
    Thread.currentThread().setContextClassLoader(originalClassLoader);
}

this is the code.

I've been using the following and type casting it to a string and checking for the nan value

   (str(df.at[index, 'column']) == 'nan')

This allows me to check specific value in a series and not just return if this is contained somewhere within the series.

Stop container by container id

docker container stop <container_id>

Remove container by container id

If don't want stop and remove, can force remove

docker container rm -f <container_id>

Remove image

Done!

yes in Virtuemart its must be button CLOSe-continue shopping, not element, because after click you can redirect.. i found this redirect bug on my ajax website.

This is how I did it.

It may be faster because it is using execute_batch:

# df is the dataframe
if len(df) > 0:
    df_columns = list(df)
    # create (col1,col2,...)
    columns = ",".join(df_columns)

    # create VALUES('%s', '%s",...) one '%s' per column
    values = "VALUES({})".format(",".join(["%s" for _ in df_columns])) 

    #create INSERT INTO table (columns) VALUES('%s',...)
    insert_stmt = "INSERT INTO {} ({}) {}".format(table,columns,values)

    cur = conn.cursor()
    psycopg2.extras.execute_batch(cur, insert_stmt, df.values)
    conn.commit()
    cur.close()

Could this do for you? Check my JSFiddle

And the code:

HTML

<div class="container">
    <div class="div1">Div 1</div>
    <div class="div2">Div 2</div>
</div>

CSS

div.container {
    background-color: #FF0000;
    margin: auto;   
    width: 304px;
}

div.div1 {
    border: 1px solid #000;
    float: left;
    width: 150px;
}

div.div2 {
    border: 1px solid red;
    float: left;
    width: 150px;
}

Normally it is quite good to do:

echo isset($_GET['id']) ? $_GET['id'] : 'wtf';

This is so when assigning the var to other variables you can do defaults all in one breath instead of constantly using if statements to just give them a default value if they are not set.

You are looking for size:

In [11]: df.groupby(['col5', 'col2']).size()
Out[11]:
col5  col2
1     A       1
      D       3
2     B       2
3     A       3
      C       1
4     B       1
5     B       2
6     B       1
dtype: int64

To get the same answer as waitingkuo (the "second question"), but slightly cleaner, is to groupby the level:

In [12]: df.groupby(['col5', 'col2']).size().groupby(level=1).max()
Out[12]:
col2
A       3
B       2
C       1
D       3
dtype: int64

• F# Has Better Performance than C# in Math
• You could use F# projects in the same solution with C# (and call from one to another)
• F# is really good for complex algorithmic programming, financial and scientific applications
• F# logically is really good for the parallel execution (it is easier to make F# code execute on parallel cores, than C#)

It's just about the remainders. Let me show you how

10 % 5=0
9 % 5=4 (because the remainder of 9 when divided by 5 is 4)
8 % 5=3
7 % 5=2
6 % 5=1

5 % 5=0 (because it is fully divisible by 5)

Now we should remember one thing, mod means remainder so

4 % 5=4

but why 4? because 5 X 0 = 0 so 0 is the nearest multiple which is less than 4 hence 4-0=4

If you're using Atom editor, you can accomplish this by the ascii-tree package.

You can write the following tree:

root
+-- dir1
    +--file1
+-- dir2
    +-- file2

and convert it to the following by selecting it and pressing ctrl-alt-t:

root
+-- dir1
¦   +-- file1
+-- dir2
    +-- file2

I've already encountered this problem on people using my in-house tools on new 64 bit machines with Office 2010.

all I had to do was change lines of code like this:

Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
    (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

To This:

#If VBA7 Then
    Private Declare PtrSafe Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
        (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#Else
    Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
        (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#End If

You will, of course want to make sure that the library you're using is available on both machines, but so far nothing I've used has been a problem.

Note that in the old VB6, PtrSafe isn't even a valid command, so it'll appear in red as though you have a compile error, but it won't actually ever give an error because the compiler will skip the first part of the if block.

Applications using the above code compile and run perfectly on Office 2003, 2007, and 2010 32 and 64 bit.

You can push your local branch to a new remote branch like so:

git push origin master:test

(Assuming origin is your remote, master is your local branch name and test is the name of the new remote branch, you wish to create.)

If at the same time you want to set up your local branch to track the newly created remote branch, you can do so with -u (on newer versions of Git) or --set-upstream, so:

git push -u origin master:test

or

git push --set-upstream origin master:test

...will create a new remote branch, named test, in remote repository origin, based on your local master, and setup your local master to track it.

If you're dealing with months and years you need something that knows how many days each month has and which years are leap years.

Enter the Gregorian Calendar (and other culture-specific Calendar implementations).

While Calendar doesn't provide methods to directly calculate the difference between two points in time, it does have methods such as

DateTime AddWeeks(DateTime time, int weeks)
DateTime AddMonths(DateTime time, int months)
DateTime AddYears(DateTime time, int years)

Method that will work. The way it is used above will not work.

declare @str varchar(50)='79136'

select 
  case 
    when  @str LIKE replicate('[0-9]',LEN(@str)) then 1

select 
  case

Or when you have an existing Dynamic Web Project, you can set/change it in Targeted Runtimes entry in project's properties. Eclipse will then automagically add all its libraries to the build path (without having a copy of them in the project!).

The only other difference is the default inheritance of classes and structs, which, unsurprisingly, is private and public respectively.

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Or use WITH NO_WAIT to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true

Most people will tell you to check your proxy settings or delete and re-add artifacts, but I will stay away from that and give another suggestion in case that doesn't turn out to be your problem. It could be your mirror settings.

If you use maven at the office then there's a good chance maven is configured to look for your company's internal maven repository. If you're doing some work from home and you are not connected to the network this could be the problem. An obvious solution might be VPN to the office to get visibility to this repo. Another way around this is to add another mirror site to your /User/.m2/settings.xml file so if it fails to find it on your office network it will try public repo.

<mirror>
    <id>Central</id>
    <url>http://repo1.maven.org/maven2</url>
    <mirrorOf>central</mirrorOf>
    <!-- United States, St. Louis-->
</mirror>

For other maven repositories take a look here: http://docs.codehaus.org/display/MAVENUSER/Mirrors+Repositories

I find jackson fasterxml is one good choice to serializing/deserializing bean with XML.

Refer: How to use spring to marshal and unmarshal xml?

This is the best help that I found:

https://atom.io/packages/atom-beautify

This package can be installed in Atom and then CTRL+ALT+B solve the problem.

So, yeah, all what you need, just comment line in INI file like zend_extension=xdebug.so or similar.

Comments can be made by adding semicolon.

But, such kind of answer already added, and I'd like to share ready solution to switch Xdebug status.

I've made quick switcher for Xdebug. Maybe it would be useful for someone.

A cleaner way of iterating the lists is:

// initialise the collection
collection = new ArrayList<ArrayList<String>>();
// iterate
for (ArrayList<String> innerList : collection) {
    for (String string : innerList) {
        // do stuff with string
    }
}

Thanks to yojimbo for his answer. To add to his sample, I wanted to use the jquery method $.getJSON which puts a random callback in the query string so I also wanted to parse that out in the Node.js. I also wanted to pass an object back and use the stringify function.

This is my Client Side code.

$.getJSON("http://localhost:8124/dummy?action=dostuff&callback=?",
function(data){
  alert(data);
},
function(jqXHR, textStatus, errorThrown) {
    alert('error ' + textStatus + " " + errorThrown);
});

This is my Server side Node.js

var http = require('http');
var querystring = require('querystring');
var url = require('url');

http.createServer(function (req, res) {
    //grab the callback from the query string   
    var pquery = querystring.parse(url.parse(req.url).query);   
    var callback = (pquery.callback ? pquery.callback : '');

    //we probably want to send an object back in response to the request
    var returnObject = {message: "Hello World!"};
    var returnObjectString = JSON.stringify(returnObject);

    //push back the response including the callback shenanigans
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end(callback + '(\'' + returnObjectString + '\')');
}).listen(8124);
