I've written something that detects if the page contains the anchor that was clicked on, and if not, goes to the normal page, otherwise it scrolls to the specific section:

$('a[href*=\\#]').on('click',function(e) {

    var target = this.hash;
    var $target = $(target);
    console.log(targetname);
    var targetname = target.slice(1, target.length);

    if(document.getElementById(targetname) != null) {
         e.preventDefault();
    }
    $('html, body').stop().animate({
        'scrollTop': $target.offset().top-120 //or the height of your fixed navigation 

    }, 900, 'swing', function () {
        window.location.hash = target;
  });
});

Do you really need that plugin? You can just animate the scrollTop property:

$("#nav ul li a[href^='#']").on('click', function(e) {

   // prevent default anchor click behavior
   e.preventDefault();

   // store hash
   var hash = this.hash;

   // animate
   $('html, body').animate({
       scrollTop: $(hash).offset().top
     }, 300, function(){

       // when done, add hash to url
       // (default click behaviour)
       window.location.hash = hash;
     });

});

Not in javascript it self but using Google Closure Compiler's advanced mode you can do that:

/**
 * @param {Date} myDate The date
 * @param {string} myString The string
 */
function myFunction(myDate, myString)
{
    //do stuff
}

See http://code.google.com/closure/compiler/docs/js-for-compiler.html

If someone would need a one liner:

iwr -Uri 'https://api.github.com/user' -Headers @{ Authorization = "Basic "+ [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes("user:pass")) }

I am working on an application in which we track live route. Passenger wants to show current position of driver and the expected arrival time to reach at his/her location. So I need to add some duration into current time.

So I found the below mentioned way to do the same. We can add any duration(hour,minutes and seconds) in our current time by moment:

var travelTime = moment().add(642, 'seconds').format('hh:mm A');// it will add 642 seconds in the current time and will give time in 03:35 PM format

var travelTime = moment().add(11, 'minutes').format('hh:mm A');// it will add 11 mins in the current time and will give time in 03:35 PM format; can use m or minutes 

var travelTime = moment().add(2, 'hours').format('hh:mm A');// it will add 2 hours in the current time and will give time in 03:35 PM format

It fulfills my requirement. May be it can help you.

This error usually occurs if you have not included the xmlns:mm properly, it occurs usually in the first line of code.

for me it was..

xmlns:mm="http://millennialmedia.com/android/schema"

that i missed in first line of the code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:mm="http://millennialmedia.com/android/schema"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_marginTop="50dp"
android:layout_marginBottom="50dp"

I had the same problem, however, it worked for me with the following settings:

bulk insert schema.table
from '\\your\data\source.csv'
with (
datafiletype = 'char'
,format = 'CSV'
,firstrow = 2
,fieldterminator = '|'
,rowterminator = '\n'
,tablock
)

My CSV-File looks like this:

"col1"|"col2"
"val1"|"val2"
"val3"|"val4"

My problem was, I had rowterminator set to '0x0a' before, it did not work. Once I changed it to '\n', it started working...

Justin(above) is accurate. However, keep in mind that depending on who you get the certificate from (intermediate CA, root CA involved or not) or how the pfx is created/exported, sometimes they could be missing the certificate chain. After Import, You would have a certificate of PrivateKeyEntry type, but with a chain of length of 1.

To fix this, there are several options. The easier option in my mind is to import and export the pfx file in IE(choosing the option of Including all the certificates in the chain). The import and export process of certificates in IE should be very easy and well documented elsewhere.

Once exported, import the keystore as Justin pointed above. Now, you would have a keystore with certificate of type PrivateKeyEntry and with a certificate chain length of more than 1.

Certain .Net based Web service clients error out(unable to establish trust relationship), if you don't do the above.

Parsing date and time

To create a LocalDateTime object from a string you can use the static LocalDateTime.parse() method. It takes a string and a DateTimeFormatter as parameter. The DateTimeFormatter is used to specify the date/time pattern.

String str = "1986-04-08 12:30";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
LocalDateTime dateTime = LocalDateTime.parse(str, formatter);

Formatting date and time

To create a formatted string out a LocalDateTime object you can use the format() method.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
LocalDateTime dateTime = LocalDateTime.of(1986, Month.APRIL, 8, 12, 30);
String formattedDateTime = dateTime.format(formatter); // "1986-04-08 12:30"

Note that there are some commonly used date/time formats predefined as constants in DateTimeFormatter. For example: Using DateTimeFormatter.ISO_DATE_TIME to format the LocalDateTime instance from above would result in the string "1986-04-08T12:30:00".

The parse() and format() methods are available for all date/time related objects (e.g. LocalDate or ZonedDateTime)

You can try something like Routes.js

import React, { Component } from 'react'
import { BrowserRouter as Router, Route } from 'react-router-dom';
import FrontPage from './FrontPage';
import Dashboard from './Dashboard';
import AboutPage from './AboutPage';
import Backend from './Backend';
import Homepage from './Homepage';
import UserPage from './UserPage';
class Routes extends Component {
    render() {
        return (
            <div>
                <Route exact path="/" component={FrontPage} />
                <Route exact path="/home" component={Homepage} />
                <Route exact path="/about" component={AboutPage} />
                <Route exact path="/admin" component={Backend} />
                <Route exact path="/admin/home" component={Dashboard} />
                <Route exact path="/users" component={UserPage} />    
            </div>
        )
    }
}

export default Routes

App.js

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import { BrowserRouter as Router, Route } from 'react-router-dom'
import Routes from './Routes';

class App extends Component {
  render() {
    return (
      <div className="App">
      <Router>
        <Routes/>
      </Router>
      </div>
    );
  }
}

export default App;

I think you can achieve the same from here also.

Give the div "runat="server" and an id and you can reference it in your code behind.

<div runat="server" id="theDiv">

In code behind:

{
    theDiv.Visible = false;
}

Timings on Excel 2013 fairly slow machine with a big bad used range million rows:

26ms Cells.Find xlPrevious method (as above)

0.4ms Sheet.UsedRange (just call it)

0.14ms Counta binary search + 0.4ms Used Range to start search (12 CountA calls)

So the Find xlPrevious is quite slow if that is of concern.

The CountA binary search approach is to first do a Used Range. Then chop the range in half and see if there are any non-empty cells in the bottom half, and then halve again as needed. It is tricky to get right.

using System.Reflection;
{
    string version = Assembly.GetEntryAssembly().GetName().Version.ToString();
}

Remarks from MSDN http://msdn.microsoft.com/en-us/library/system.reflection.assembly.getentryassembly%28v=vs.110%29.aspx:

The GetEntryAssembly method can return null when a managed assembly has been loaded from an unmanaged application. For example, if an unmanaged application creates an instance of a COM component written in C#, a call to the GetEntryAssembly method from the C# component returns null, because the entry point for the process was unmanaged code rather than a managed assembly.

I did work on something like this once, but sending a video and playing it in real time is a really complex thing. I suggest you work with PNG's only. In my implementation What i did was capture PNGs using the host camera and then sending them over the network to the client, Which will display the image as soon as received and request the next image from the host. Since you are on wifi that communication will be fast enough to get around 8-10 images per-second(approximation only, i worked on Bluetooth). So this will look like a continuous video but with much less effort. For communication you may use UDP sockets(Faster and less complex) or DLNA (Not sure how that works).

Alternatively, you can give the "full location" to the database in your queries a la:

SELECT photo_id FROM [my database name].photogallery;

If using one more often than others, use USE. Even if you do, you can still use the database.table syntax.

Long story short: you set some dimensions and let NumPy set the remaining(s).

(userDim1, userDim2, ..., -1) -->>

(userDim1, userDim1, ..., TOTAL_DIMENSION - (userDim1 + userDim2 + ...))

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

After installing OpenSSL, you need to restart your computer and use Run As Administrator. Then its works.

Recently faced a problem with fetching 'Origin' request header, then I found this question. But pretty confused with the results, req.get('host') is deprecated, that's why giving Undefined. Use,

    req.header('Origin');
    req.header('Host');
    // this method can be used to access other request headers like, 'Referer', 'User-Agent' etc.

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

Use the str accessor with square brackets:

df['col'] = df['col'].str[:9]

Or str.slice:

df['col'] = df['col'].str.slice(0, 9)

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

check field execution_status

0 - Returns only those jobs that are not idle or suspended.
1 - Executing.
2 - Waiting for thread.
3 - Between retries.
4 - Idle.
5 - Suspended.
7 - Performing completion actions.

If you need the result of execution, check the field last_run_outcome

0 = Failed
1 = Succeeded
3 = Canceled
5 = Unknown

docker ps will reveal the list of containers running on docker. Find the one running on your needed port and note down its PID.

Stop and remove that container using following commands:

docker stop PID
docker rm PID

Now run docker-compose up and your services should run as you have freed the needed port.

I am using justify-content-center class to a row within a container. Works well with Bootstrap 4.

<div class="container-fluid">
  <div class="row justify-content-center">
   <img src="logo.png" />
  </div>
</div>

In my case (OS X) it was because I have set GOPATH to /home/username/go (as per the book) instead of /Users/username/go

String s1 = "Welcome"; // Does not create a new instance  
String s2 = new String("Welcome"); // Creates two objects and one reference variable  

s = 'hi how are you'
l = list(map(lambda x: x,s.split()))
print(l)

Output: ['hi', 'how', 'are', 'you']

The OP did not specify or Tag the post to indicate the context (programming language, editor, tool) the Regex will be used within.

For me, I sometimes need to do this while editing a file using Textpad.

Textpad supports some Regex, but does not support lookahead or lookbehind, so it takes a few steps.

If I am looking to retain all lines that Do NOT contain the string hede, I would do it like this:

1. Search/replace the entire file to add a unique "Tag" to the beginning of each line containing any text.

    Search string:^(.)  
    Replace string:<@#-unique-#@>\1  
    Replace-all  

2. Delete all lines that contain the string hede (replacement string is empty):

    Search string:<@#-unique-#@>.*hede.*\n  
    Replace string:<nothing>  
    Replace-all  

3. At this point, all remaining lines Do NOT contain the string hede. Remove the unique "Tag" from all lines (replacement string is empty):

    Search string:<@#-unique-#@>
    Replace string:<nothing>  
    Replace-all  

Now you have the original text with all lines containing the string hede removed.

If I am looking to Do Something Else to only lines that Do NOT contain the string hede, I would do it like this:

1. Search/replace the entire file to add a unique "Tag" to the beginning of each line containing any text.

    Search string:^(.)  
    Replace string:<@#-unique-#@>\1  
    Replace-all  

2. For all lines that contain the string hede, remove the unique "Tag":

    Search string:<@#-unique-#@>(.*hede)
    Replace string:\1  
    Replace-all  

3. At this point, all lines that begin with the unique "Tag", Do NOT contain the string hede. I can now do my Something Else to only those lines.

4. When I am done, I remove the unique "Tag" from all lines (replacement string is empty):

    Search string:<@#-unique-#@>
    Replace string:<nothing>  
    Replace-all  

For each works with JQuery as in

$(<selector>).each(function() {
   //this points to item
   alert('<msg>');
});

JQuery also, for a popup, has in the UI library a dialog widget: http://jqueryui.com/demos/dialog/

Check it out, works really well.

hi @JackSlayer94 please find the below example to understand how to make an array of size 5.

class Hero {_x000D_
    name: string;_x000D_
    constructor(text: string) {_x000D_
        this.name = text;_x000D_
    }_x000D_
_x000D_
    display() {_x000D_
        return "Hello, " + this.name;_x000D_
    }_x000D_
_x000D_
}_x000D_
_x000D_
let heros:Hero[] = new Array(5);_x000D_
for (let i = 0; i < 5; i++){_x000D_
    heros[i] = new Hero("Name: " + i);_x000D_
}_x000D_
_x000D_
for (let i = 0; i < 5; i++){_x000D_
    console.log(heros[i].display());_x000D_
}

Many years later there seems to still be a usability problem with the Python logger. Here's some explanations with examples:

import logging
# This sets the root logger to write to stdout (your console).
# Your script/app needs to call this somewhere at least once.
logging.basicConfig()

# By default the root logger is set to WARNING and all loggers you define
# inherit that value. Here we set the root logger to NOTSET. This logging
# level is automatically inherited by all existing and new sub-loggers
# that do not set a less verbose level.
logging.root.setLevel(logging.NOTSET)

# The following line sets the root logger level as well.
# It's equivalent to both previous statements combined:
logging.basicConfig(level=logging.NOTSET)


# You can either share the `logger` object between all your files or the
# name handle (here `my-app`) and call `logging.getLogger` with it.
# The result is the same.
handle = "my-app"
logger1 = logging.getLogger(handle)
logger2 = logging.getLogger(handle)
# logger1 and logger2 point to the same object:
# (logger1 is logger2) == True


# Convenient methods in order of verbosity from highest to lowest
logger.debug("this will get printed")
logger.info("this will get printed")
logger.warning("this will get printed")
logger.error("this will get printed")
logger.critical("this will get printed")


# In large applications where you would like more control over the logging,
# create sub-loggers from your main application logger.
component_logger = logger.getChild("component-a")
component_logger.info("this will get printed with the prefix `my-app.component-a`")

# If you wish to control the logging levels, you can set the level anywhere 
# in the hierarchy:
#
# - root
#   - my-app
#     - component-a
#

# Example for development:
logger.setLevel(logging.DEBUG)

# If that prints too much, enable debug printing only for your component:
component_logger.setLevel(logging.DEBUG)


# For production you rather want:
logger.setLevel(logging.WARNING)

A common source of confusion comes from a badly initialised root logger. Consider this:

import logging
log = logging.getLogger("myapp")
log.warning("woot")
logging.basicConfig()
log.warning("woot")

Output:

woot
WARNING:myapp:woot

Depending on your runtime environment and logging levels, the first log line (before basic config) might not show up anywhere.

The git merge-base command can be used to find a common ancestor. So if my_experiment has not been merged into master yet and my_experiment was created from master you could:

git log --oneline `git merge-base my_experiment master`..my_experiment

I got this error in a JobService from the following code:

    BluetoothLeScanner bluetoothLeScanner = getBluetoothLeScanner();
    if (BluetoothAdapter.STATE_ON == getBluetoothAdapter().getState() && null != bluetoothLeScanner) {
        // ...

        getBluetoothAdapter().enable();

Edited the answer, thanks to the prompting of some comments:

Should avoid recommending utf8. It's almost never what you want, and often leads to unexpected messes. The utf8 character set is not fully compatible with UTF-8. The utf8mb4 character set is what you want if you want UTF-8. – Rich Remer Mar 28 '18 at 23:41

and

That seems quite important, glad I read the comments and thanks @RichRemer . Nikki , I think you should edit that in your answer considering how many views this gets. See here https://dev.mysql.com/doc/refman/8.0/en/charset-unicode-utf8.html and here What is the difference between utf8mb4 and utf8 charsets in MySQL? – Paulpro Mar 12 at 17:46

This line looks questionable:

page_output.innerHTML = str_output;

You can use .innerHTML within jQuery, or you can use it without, but you have to address the selector semantically one way or the other:

$('#page_output').innerHTML /* for jQuery */
document.getElementByID('page_output').innerHTML /* for standard JS */

or better yet

$('#page_output').html(str_output);

Content that is floating does not influence the height of its container. The element contains no content that isn't floating (so nothing stops the height of the container being 0, as if it were empty).

Setting overflow: hidden on the container will avoid that by establishing a new block formatting context. See methods for containing floats for other techniques and containing floats for an explanation about why CSS was designed this way.

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Read more here - https://docs.gradle.org/current/userguide/gradle_wrapper.html

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

I had the same problem (openssl) and this worked for me on Ubuntu 14.04.1 LTS. The solution is the same up to Ubuntu 18.04 (tested).

sudo apt-get install libssl-dev

If that empty Date really bugs you, you can also to create a simpler Time structure:

// more work is required to make this even close to production ready
class Time
{
    // TODO: don't forget to add validation
    public int Hours   { get; set; }
    public int Minutes { get; set; }
    public int Seconds { get; set; }

    public override string ToString()
    {  
        return String.Format(
            "{0:00}:{1:00}:{2:00}",
            this.Hours, this.Minutes, this.Seconds);
    }
}

Or, why to bother: if you don't need to do any calculation with that information, just store it as String.

If elements are always nearly sorted as in your example then builtin .sort() (timsort) should be fast:

>>> a = [1,1,2]
>>> b = [1,2,2]
>>> a.sort()
>>> b.sort()
>>> a == b
False

If you don't want to sort inplace you could use sorted().

In practice it might always be faster then collections.Counter() (despite asymptotically O(n) time being better then O(n*log(n)) for .sort()). Measure it; If it is important.

Quick summary:

import "math/bits"
const (
    MaxUint uint = (1 << bits.UintSize) - 1
    MaxInt int = (1 << bits.UintSize) / 2 - 1
    MinInt int = (1 << bits.UintSize) / -2
)

Background:

As I presume you know, the uint type is the same size as either uint32 or uint64, depending on the platform you're on. Usually, one would use the unsized version of these only when there is no risk of coming close to the maximum value, as the version without a size specification can use the "native" type, depending on platform, which tends to be faster.

Note that it tends to be "faster" because using a non-native type sometimes requires additional math and bounds-checking to be performed by the processor, in order to emulate the larger or smaller integer. With that in mind, be aware that the performance of the processor (or compiler's optimised code) is almost always going to be better than adding your own bounds-checking code, so if there is any risk of it coming into play, it may make sense to simply use the fixed-size version, and let the optimised emulation handle any fallout from that.

With that having been said, there are still some situations where it is useful to know what you're working with.

The package "math/bits" contains the size of uint, in bits. To determine the maximum value, shift 1 by that many bits, minus 1. ie: (1 << bits.UintSize) - 1

Note that when calculating the maximum value of uint, you'll generally need to put it explicitly into a uint (or larger) variable, otherwise the compiler may fail, as it will default to attempting to assign that calculation into a signed int (where, as should be obvious, it would not fit), so:

const MaxUint uint = (1 << bits.UintSize) - 1

That's the direct answer to your question, but there are also a couple of related calculations you may be interested in.

According to the spec, uint and int are always the same size.

uint either 32 or 64 bits

int same size as uint

So we can also use this constant to determine the maximum value of int, by taking that same answer and dividing by 2 then subtracting 1. ie: (1 << bits.UintSize) / 2 - 1

And the minimum value of int, by shifting 1 by that many bits and dividing the result by -2. ie: (1 << bits.UintSize) / -2

In summary:

MaxUint: (1 << bits.UintSize) - 1

MaxInt: (1 << bits.UintSize) / 2 - 1

MinInt: (1 << bits.UintSize) / -2

full example (should be the same as below)

package main

import "fmt"
import "math"
import "math/bits"

func main() {
    var mi32 int64 = math.MinInt32
    var mi64 int64 = math.MinInt64

    var i32 uint64 = math.MaxInt32
    var ui32 uint64 = math.MaxUint32
    var i64 uint64 = math.MaxInt64
    var ui64 uint64 = math.MaxUint64
    var ui uint64 = (1 << bits.UintSize) - 1
    var i uint64 = (1 << bits.UintSize) / 2 - 1
    var mi int64 = (1 << bits.UintSize) / -2

    fmt.Printf(" MinInt32: %d\n", mi32)
    fmt.Printf(" MaxInt32:  %d\n", i32)
    fmt.Printf("MaxUint32:  %d\n", ui32)
    fmt.Printf(" MinInt64: %d\n", mi64)
    fmt.Printf(" MaxInt64:  %d\n", i64)
    fmt.Printf("MaxUint64:  %d\n", ui64)
    fmt.Printf("  MaxUint:  %d\n", ui)
    fmt.Printf("   MinInt: %d\n", mi)
    fmt.Printf("   MaxInt:  %d\n", i)
}

i solved this by running CMD in administration mode, so try this.

//example
char character;//to be scanned
char merge[2];// this is just temporary array to merge with      
merge[0] = character;
merge[1] = '\0';
//now you have changed it into a string

Wasted almost one hour, didn't find a solution, so I wanted to contribute =)

In my case, I was importing WRONGLY the component.. like below:

import { MyComponent } from './components/MyComponent'

But the CORRECT is (without curly braces):

import MyComponent from './components/MyComponent'

If you want to set different color for clicked and unclicked radio button just use:

   android:buttonTint="@drawable/radiobutton"  in xml of the radiobutton and your radiobutton.xml will be:  
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#1E88E5"/>
<item android:state_checked="true" android:color="#00e676"/>
<item android:color="#ffffff"/>

This is a method for converting a svg picture to a gif using standard php GD tools

1) You put the image into a canvas element in the browser:

<canvas id=myCanvas></canvas>

<script>
var Key='picturename'
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
base_image = new Image();
base_image.src = myimage.svg;
base_image.onload = function(){

    //get the image info as base64 text string

    var dataURL = canvas.toDataURL();
    //Post the image (dataURL) to the server using jQuery post method
    $.post('ProcessPicture.php',{'TheKey':Key,'image': dataURL ,'h': canvas.height,'w':canvas.width,"stemme":stemme } ,function(data,status){ alert(data+' '+status) });
}
</script>    

And then convert it at the server (ProcessPicture.php) from (default) png to gif and save it. (you could have saved as png too then use imagepng instead of image gif):

//receive the posted data in php
$pic=$_POST['image'];
$Key=$_POST['TheKey'];
$height=$_POST['h'];
$width=$_POST['w'];
$dir='../gif/'
$gifName=$dir.$Key.'.gif';
 $pngName=$dir.$Key.'.png';

//split the generated base64 string before the comma. to remove the 'data:image/png;base64, header  created by and get the image data
$data = explode(',', $pic);
$base64img = base64_decode($data[1]);
$dimg=imagecreatefromstring($base64img); 

//in order to avoid copying a black figure into a (default) black background you must create a white background

$im_out = ImageCreateTrueColor($width,$height);
$bgfill = imagecolorallocate( $im_out, 255, 255, 255 );
imagefill( $im_out, 0,0, $bgfill );

//Copy the uploaded picture in on the white background
ImageCopyResampled($im_out, $dimg ,0, 0, 0, 0, $width, $height,$width, $height);

//Make the gif and png file 
imagegif($im_out, $gifName);
imagepng($im_out, $pngName);

If you're on Linux/Unix you could avoid call() altogether and not execute an entirely new instance of the Python executable and its environment.

import os

cpid = os.fork()
if not cpid:
    import somescript
    os._exit(0)

os.waitpid(cpid, 0)

For what it's worth.

Just ask it for the objectForKey:@"b". If it returns nil, no object is set at that key.

if ([xyz objectForKey:@"b"]) {
    NSLog(@"There's an object set for key @\"b\"!");
} else {
    NSLog(@"No object set for key @\"b\"");
}

Edit: As to your edited second question, it's simply NSUInteger mCount = [xyz count];. Both of these answers are documented well and easily found in the NSDictionary class reference ([1] [2]).

Well nobody answered - which is in part the fault of the question : the input string contains eleven fields (this much can be inferred) but how many tabs ? Most possibly exactly 10. Then the answer is

String s = "\t2\t\t4\t5\t6\t\t8\t\t10\t";
String[] fields = s.split("\t", -1);  // in your case s.split("\t", 11) might also do
for (int i = 0; i < fields.length; ++i) {
    if ("".equals(fields[i])) fields[i] = null;
}
System.out.println(Arrays.asList(fields));
// [null, 2, null, 4, 5, 6, null, 8, null, 10, null]
// with s.split("\t") : [null, 2, null, 4, 5, 6, null, 8, null, 10]

If the fields happen to contain tabs this won't work as expected, of course.
The -1 means : apply the pattern as many times as needed - so trailing fields (the 11th) will be preserved (as empty strings ("") if absent, which need to be turned to null explicitly).

If on the other hand there are no tabs for the missing fields - so "5\t6" is a valid input string containing the fields 5,6 only - there is no way to get the fields[] via split.

Swift 4.2

var base64String = "my fancy string".data(using: .utf8, allowLossyConversion: false)?.base64EncodedString()

to decode, see (from https://gist.github.com/stinger/a8a0381a57b4ac530dd029458273f31a)

//: # Swift 3: Base64 encoding and decoding
import Foundation

extension String {
//: ### Base64 encoding a string
    func base64Encoded() -> String? {
        if let data = self.data(using: .utf8) {
            return data.base64EncodedString()
        }
        return nil
    }

//: ### Base64 decoding a string
    func base64Decoded() -> String? {
        if let data = Data(base64Encoded: self) {
            return String(data: data, encoding: .utf8)
        }
        return nil
    }
}
var str = "Hello, playground"
print("Original string: \"\(str)\"")

if let base64Str = str.base64Encoded() {
    print("Base64 encoded string: \"\(base64Str)\"")
    if let trs = base64Str.base64Decoded() {
        print("Base64 decoded string: \"\(trs)\"")
        print("Check if base64 decoded string equals the original string: \(str == trs)")
    }
}

Google Guava

If you're using Guava, you can take a functional approach and do the following

FluentIterable.from(list).find(new Predicate<MyObject>() {
   public boolean apply(MyObject input) {
      return "John".equals(input.getName());
   }
}).Any();

which looks a little verbose. However the predicate is an object and you can provide different variants for different searches. Note how the library itself separates the iteration of the collection and the function you wish to apply. You don't have to override equals() for a particular behaviour.

As noted below, the java.util.Stream framework built into Java 8 and later provides something similar.

<strong> and <em> - unlike <b> and <i> - have clear purpose for web browsers for the blind.

A blind person doesn't browse the web visually, but by sound such as text readers. <strong> and <em>, in addition to encouraging something to be bold or italic, also convey loudness or stressing syllables respectively (OH MY! & Ooooooh Myyyyyyy!). Audio-only browsers are unpredictable when it comes to <b> and <i>... they may make them loud or stress them or they may not... you never can be sure unless you use <strong> and <em>.

If you set the x:Name property to each TabItem as:

<TabControl x:Name="MyTab" SelectionChanged="TabControl_SelectionChanged">
    <TabItem x:Name="MyTabItem1" Header="One"/>
    <TabItem x:Name="MyTabItem2" Header="2"/>
    <TabItem x:Name="MyTabItem3" Header="Three"/>
</TabControl>

Then you can access to each TabItem at the event:

private void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (MyTabItem1.IsSelected)
    // do your stuff
    if (MyTabItem2.IsSelected)
    // do your stuff
    if (MyTabItem3.IsSelected)
    // do your stuff
}

You were setting BCC but then overwriting the variable with the FROM

$to = "[email protected]";
     $subject .= "".$emailSubject."";
 $headers .= "Bcc: ".$emailList."\r\n";
 $headers .= "From: [email protected]\r\n" .
     "X-Mailer: php";
     $headers .= "MIME-Version: 1.0\r\n";
     $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
 $message = '<html><body>';
 $message .= 'THE MESSAGE FROM THE FORM';

     if (mail($to, $subject, $message, $headers)) {
     $sent = "Your email was sent!";
     } else {
      $sent = ("Error sending email.");
     }

One problem is that you are using count to refer both to the position in the word that you are checking, and the number of char you have seen, and you are using char to refer both to the input character you are checking, and the current character in the string. Use separate variables instead.

Also, move the return statement outside the loop; otherwise you will always return after checking the first character.

Finally, you only need one loop to iterate over the string. Get rid of the outer while loop and you will not need to track the position in the string.

Taking these suggestions, your code would look like this:

def count_letters(word, char):
  count = 0
  for c in word:
    if char == c:
      count += 1
  return count

Change the 5 to 5.0. You're getting integer division.

The proper way would be to use $_SERVER["PHP_SELF"] (in conjunction with htmlspecialchars to avoid possible exploits). You can also just skip the action= part empty, which is not W3C valid, but currently works in most (all?) browsers - the default is to submit to self if it's empty.

Here is an example form that takes a name and email, and then displays the values you have entered upon submit:

<?php if (!empty($_POST)): ?>
    Welcome, <?php echo htmlspecialchars($_POST["name"]); ?>!<br>
    Your email is <?php echo htmlspecialchars($_POST["email"]); ?>.<br>
<?php else: ?>
    <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
        Name: <input type="text" name="name"><br>
        Email: <input type="text" name="email"><br>
        <input type="submit">
    </form>
<?php endif; ?>

And if you add an alias for it then it's even better right?

git config --global alias.nccommit 'commit -a --allow-empty-message -m ""'

Now you just do an nccommit, nc because of no comment, and everything should be commited.

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView wb = new WebView(this);
        wb.loadUrl("file:///android_asset/index.html");
        setContentView(wb);
    }


keep your .html in `asset` folder

Actually, "narrow" or "partial" or "sparse" checkouts are under current, heavy development for Git. Note, you'll still have the full repository under .git. So, the other two posts are current for the current state of Git but it looks like we will be able to do sparse checkouts eventually. Checkout the mailing lists if you're interested in more details -- they're changing rapidly.

You are looking for the insert function, found in the table section of the main library.

foo = {}
table.insert(foo, "bar")
table.insert(foo, "baz")

To destroy the previous contents of the file, then write a new string to the file:

open('myfile.txt', 'w') { |f| f << "some text or data structures..." } 

To append to a file without overwriting its old contents:

open('myfile.txt', "a") { |f| f << 'I am appended string' } 

    WITH CTE_SUM AS (
      SELECT ProductID, Sum(OrderQuantity) AS TotalOrderQuantity 
      FROM OrderDetails GROUP BY ProductID
    )
    SELECT DISTINCT OrderDetails.ProductID, OrderDetails.ProductName, OrderDetails.OrderQuantity,CTE_SUM.TotalOrderQuantity 
    FROM 
    OrderDetails INNER JOIN CTE_SUM 
    ON OrderDetails.ProductID = CTE_SUM.ProductID

Please check if this works.

If that's so bothering, you could try to switch to windows explorer alternative like freecommander which has a toolbar button for that purpose.

If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE

Edit: On the model overview it's under Physical Schemata

Screenshot:

I tried all of the above, nothing worked for me. Then I changed tomcat port numbers both HTTP/1.1 and Tomcat admin port and it got solved.

I see other solutions above worked for the people but it is worth to try this one if any of the above doesn't work.

Thanks everyone!

The fact that mongoDB is not relational have led some people to consider it useless. I think that you should know what you are doing before designing a DB. If you choose to use noSQL DB such as MongoDB, you better implement a schema. This will make your collections - more or less - resemble tables in SQL databases. Also, avoid denormalization (embedding), unless necessary for efficiency reasons.

If you want to design your own noSQL database, I suggest to have a look on Firebase documentation. If you understand how they organize the data for their service, you can easily design a similar pattern for yours.

As others pointed out, you will have to do the joins client-side, except with Meteor (a Javascript framework), you can do your joins server-side with this package (I don't know of other framework which enables you to do so). However, I suggest you read this article before deciding to go with this choice.

Edit 28.04.17: Recently Firebase published this excellent series on designing noSql Databases. They also highlighted in one of the episodes the reasons to avoid joins and how to get around such scenarios by denormalizing your database.

Assume i have two arrays. The first one has student details and the student marks details. Both arrays have the common key, that is ‘studentId’

let studentDetails = [
  { studentId: 1, studentName: 'Sathish', gender: 'Male', age: 15 },
  { studentId: 2, studentName: 'kumar', gender: 'Male', age: 16 },
  { studentId: 3, studentName: 'Roja', gender: 'Female', age: 15 },
  {studentId: 4, studentName: 'Nayanthara', gender: 'Female', age: 16},
];

let studentMark = [
  { studentId: 1, mark1: 80, mark2: 90, mark3: 100 },
  { studentId: 2, mark1: 80, mark2: 90, mark3: 100 },
  { studentId: 3, mark1: 80, mark2: 90, mark3: 100 },
  { studentId: 4, mark1: 80, mark2: 90, mark3: 100 },
];

I want to merge the two arrays based on the key ‘studentId’. I have created a function to merge the two arrays.

const mergeById = (array1, array2) =>
    array1.map(itm => ({
      ...array2.find((item) => (item.studentId === itm.studentId) && item),
      ...itm
    }));

here is the code to get the final result

let result = mergeById(studentDetails, studentMark);

[
{"studentId":1,"mark1":80,"mark2":90,"mark3":100,"studentName":"Sathish","gender":"Male","age":15},{"studentId":2,"mark1":80,"mark2":90,"mark3":100,"studentName":"kumar","gender":"Male","age":16},{"studentId":3,"mark1":80,"mark2":90,"mark3":100,"studentName":"Roja","gender":"Female","age":15},{"studentId":4,"mark1":80,"mark2":90,"mark3":100,"studentName":"Nayanthara","gender":"Female","age":16}
]

First you create a UIImage from your image file, then create a UIImageView from that:

let imageName = "yourImage.png"
let image = UIImage(named: imageName)
let imageView = UIImageView(image: image!)

Finally you'll need to give imageView a frame and add it your view for it to be visible:

imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
view.addSubview(imageView)

when(
  fooDao.getBar(
    any(Bazoo.class)
  )
).thenReturn(myFoo);

or (to avoid nulls):

when(
  fooDao.getBar(
    (Bazoo)notNull()
  )
).thenReturn(myFoo);

Don't forget to import matchers (many others are available):

For Mockito 2.1.0 and newer:

import static org.mockito.ArgumentMatchers.*;

For older versions:

I had a similar problem.

As it turned out, I ran mvn clean package install.

Correct way is mvn clean install

1. Use HTTP Basic Auth to authenticate clients, but treat username/password only as temporary session token.
   
   The session token is just a header attached to every HTTP request, eg: Authorization: Basic Ym9ic2Vzc2lvbjE6czNjcmV0
   
   The string Ym9ic2Vzc2lvbjE6czNjcmV0 above is just the string "bobsession1:s3cret" (which is a username/password) encoded in Base64.

2. To obtain the temporary session token above, provide an API function (eg: http://mycompany.com/apiv1/login) which takes master-username and master-password as an input, creates a temporary HTTP Basic Auth username / password on the server side, and returns the token (eg: Ym9ic2Vzc2lvbjE6czNjcmV0). This username / password should be temporary, it should expire after 20min or so.

3. For added security ensure your REST service are served over HTTPS so that information are not transferred plaintext

If you're on Java, Spring Security library provides good support to implement above method

Arrays.asList does not return instance of java.util.ArrayListbut it returns instance of java.util.Arrays.ArrayList.

You will need to convert to ArrayList if you want to access ArrayList specific information

allWords.addAll(Arrays.asList(strTemp.toLowerCase().split("\\s+")));

You can do it in this way

private EditText nameEdit;
private EditText emailEdit;
private String nameDefaultValue = "Your Name";
private String emailDefaultValue = "[email protected]";

and inside onCreate method

nameEdit = (EditText) findViewById(R.id.name);
    nameEdit.setText(nameDefaultValue); 
    nameEdit.setOnTouchListener( new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (nameEdit.getText().toString().equals(nameDefaultValue)){
                nameEdit.setText("");
            }
            return false;
        }
    });

    nameEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {               
            if(!hasFocus && TextUtils.isEmpty(nameEdit.getText().toString())){
                nameEdit.setText(nameDefaultValue);
            } else if (hasFocus && nameEdit.getText().toString().equals(nameDefaultValue)){
                nameEdit.setText("");
            }
        }
    });     

    emailEdit = (EditText)findViewById(R.id.email);
    emailEdit.setText(emailDefaultValue);   
    emailEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {               
            if(!hasFocus && TextUtils.isEmpty(emailEdit.getText().toString())){
                emailEdit.setText(emailDefaultValue);
            } else if (hasFocus && emailEdit.getText().toString().equals(emailDefaultValue)){
                emailEdit.setText("");
            }
        }
    });

Steps:

1. Create a CSR Using Key Chain Access
2. Create a P12 Using Key Chain Access using private key
3. APNS App ID and certificate

This gives you three files:

• The CSR
• The private key as a p12 file (PushChatKey.p12)
• The SSL certificate, aps_development.cer

Go to the folder where you downloaded the files, in my case the Desktop:

$ cd ~/Desktop/

Convert the .cer file into a .pem file:

$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem

Convert the private key’s .p12 file into a .pem file:

$ openssl pkcs12 -nocerts -out PushChatKey.pem -in PushChatKey.p12

Enter Import Password:

MAC verified OK Enter PEM pass phrase: Verifying - Enter PEM pass phrase:

You first need to enter the passphrase for the .p12 file so that openssl can read it. Then you need to enter a new passphrase that will be used to encrypt the PEM file. Again for this tutorial I used “pushchat” as the PEM passphrase. You should choose something more secure. Note: if you don’t enter a PEM passphrase, openssl will not give an error message but the generated .pem file will not have the private key in it.

Finally, combine the certificate and key into a single .pem file:

$ cat PushChatCert.pem PushChatKey.pem > ck.pem

Make sure that you have set your application-site version from v2.0 to v4.0 in IIS Manager:

Application Pools > Your Application > Advanced Settings > .NET Framework Version

After that, install your ASP.NET.

For 32-Bit OS (Windows):

C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

For 64-Bit OS (Windows):

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

Restart your application-site in IIS Manager and enjoy.

Where you declare the myclass[] array as :

xClass myclass[] = new xClass[10]

, simply pass in as an argument the number of XClass elements you'll need. At that point do you know how many you will need? By declaring the array as having 10 elements, you are not declaring 10 XClass objects, you're simply creating an array with 10 elements of type xClass.

I benchmarked it multiple times on Google Chrome 52, but feel free to copypaste it into any other browser's console.

~ 1500 ms, includes (~ 2700 ms when I used the polyfill)

var array = [0,1,2,3,4,5,6,7,8,9]; 
var result = 0;

var start = new Date().getTime();
for(var i = 0; i < 10000000; i++)
{
  if(array.includes("test") === true){ result++; }
}
console.log(new Date().getTime() - start);

~ 1050 ms, indexOf

var array = [0,1,2,3,4,5,6,7,8,9]; 
var result = 0;

var start = new Date().getTime();
for(var i = 0; i < 10000000; i++)
{
  if(array.indexOf("test") > -1){ result++; }
}
console.log(new Date().getTime() - start);

~ 650 ms, custom function

function inArray(target, array)
{

/* Caching array.length doesn't increase the performance of the for loop on V8 (and probably on most of other major engines) */

  for(var i = 0; i < array.length; i++) 
  {
    if(array[i] === target)
    {
      return true;
    }
  }

  return false; 
}

var array = [0,1,2,3,4,5,6,7,8,9]; 
var result = 0;

var start = new Date().getTime();
for(var i = 0; i < 10000000; i++)
{
  if(inArray("test", array) === true){ result++; }
}
console.log(new Date().getTime() - start);

If you are using an implementation of InputStream, you can check the result of InputStream#markSupported() that tell you whether or not you can use the method mark() / reset().

If you can mark the stream when you read, then call reset() to go back to begin.

If you can't you'll have to open a stream again.

Another solution would be to convert InputStream to byte array, then iterate over the array as many time as you need. You can find several solutions in this post Convert InputStream to byte array in Java using 3rd party libs or not. Caution, if the read content is too big you might experience some memory troubles.

Finally, if your need is to read image, then use :

BufferedImage image = ImageIO.read(new URL("http://www.example.com/images/toto.jpg"));

Using ImageIO#read(java.net.URL) also allows you to use cache.

I would do it using a for loop as shown below :

def determine_period(universe_array):
    tmp = universe_array
    for period in xrange(1, 13):
        tmp = apply_rules(tmp)
        if numpy.array_equal(tmp, universe_array):
            return period
    return 0

1. Update Maven Project and check the option "Force update of Snapshots/Releases", it will remove errors.
2. If not, Maven clean and install the Project.
3. Still the error isn't removed, repeat step 1.

It worked for me :)

If you are using Maven, run this command in your project directory

mvn clean package

You can't really do this without some form of scripting to the best of my knowledge.

<form id="my_form">
<!-- Your Form -->    
<a href="javascript:{}" onclick="document.getElementById('my_form').submit(); return false;">submit</a>
</form>

Example from Here.

GregorianCalendar c = GregorianCalendar.from((LocalDate.parse("2016-06-22")).atStartOfDay(ZoneId.systemDefault()));
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

As mentioned before use apache commons codec. It's recommended by Spring guys as well (see DigestUtils in Spring doc). E.g.:

DigestUtils.sha1Hex(b);

Definitely wouldn't use the top rated answer here.

Try using sed as mentioned on http://linuxcommando.blogspot.com/2008/03/using-sed-to-extract-lines-in-text-file.html. For example use

sed '2,4!d' somefile.txt

to print from the second line to the fourth line of somefile.txt. (And don't forget to check http://www.grymoire.com/Unix/Sed.html, sed is a wonderful tool.)

You might find mimeTeX useful.

You can use

<video src="..." ... controlsList="nodownload">

https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/controlsList

It doesn't prevent saving the video, but it does remove the download button and the "Save as" option in the context menu.

Maybe somebody can be interested, the following worked for me for the py2exe package. (I have windows 7 64 bit and portable python 2.7, Visual Studio 2005 Express with Windows SDK for Windows 7 and .NET Framework 4)

set VS90COMNTOOLS=%VS80COMNTOOLS%

then:

python.exe setup.py install

If anybody still looking at this question, the currently accepted answer is now outdated:

Since Python 3.7* the dictionaries are order-preserving, that is they now behave exactly as collections.OrderedDicts used to. Unfortunately, there is still no dedicated method to index into keys() / values() of the dictionary, so getting the first key / value in the dictionary can be done as

first_key = list(colors)[0]
first_val = list(colors.values())[0]

or alternatively (this avoids instantiating the keys view into a list):

def get_first_key(dictionary):
    for key in dictionary:
        return key
    raise IndexError

first_key = get_first_key(colors)
first_val = colors[first_key]

If you need an n-th key, then similarly

def get_nth_key(dictionary, n=0):
    if n < 0:
        n += len(dictionary)
    for i, key in enumerate(dictionary.keys()):
        if i == n:
            return key
    raise IndexError("dictionary index out of range") 

(*CPython 3.6 already included ordered dicts, but this was only an implementation detail. The language specification includes ordered dicts from 3.7 onwards.)

q = input("Apple")
w = input("Ball")
Definition = {'apple': q, 'ball': w}

These posts apparently are in the wrong order! This is #1 in a series of 3 posts. Sorry.

In attempting to use Lie Ryan's code, I had problems retrieving stored information. The vector's elements are not stored contiguously,as you can see by "cheating" a bit and storing the pointer to each element's address (which of course defeats the purpose of the dynamic array concept) and examining them.

With a bit of tinkering, via:

ss_vector* vector; // pull this out to be a global vector

// Then add the following to attempt to recover stored values.

int return_id_value(int i,apple* aa) // given ptr to component,return data item
{   printf("showing apple[%i].id = %i and  other_id=%i\n",i,aa->id,aa->other_id);
    return(aa->id);
}

int Test(void)  // Used to be "main" in the example
{   apple* aa[10]; // stored array element addresses
    vector = ss_init_vector(sizeof(apple));
    // inserting some items
    for (int i = 0; i < 10; i++)
    {   aa[i]=init_apple(i);
        printf("apple id=%i and  other_id=%i\n",aa[i]->id,aa[i]->other_id);
        ss_vector_append(vector, aa[i]);
     }   
 // report the number of components
 printf("nmbr of components in vector = %i\n",(int)vector->size);
 printf(".*.*array access.*.component[5] = %i\n",return_id_value(5,aa[5]));
 printf("components of size %i\n",(int)sizeof(apple));
 printf("\n....pointer initial access...component[0] = %i\n",return_id_value(0,(apple *)&vector[0]));
 //.............etc..., followed by
 for (int i = 0; i < 10; i++)
 {   printf("apple[%i].id = %i at address %i, delta=%i\n",i,    return_id_value(i,aa[i]) ,(int)aa[i],(int)(aa[i]-aa[i+1]));
 }   
// don't forget to free it
ss_vector_free(vector);
return 0;
}

It's possible to access each array element without problems, as long as you know its address, so I guess I'll try adding a "next" element and use this as a linked list. Surely there are better options, though. Please advise.

This error also occurs when you try to use the result of getwd() directly in the path. The problem is the missingness of the "/" at the end. Try the following code:

projectFolder <- paste(getwd(), "/", sep = '')

The paste() is to concatenate the forward slash at the end.

There are 94 Unicode characters which can be represented as one byte according to the JSON spec (if your JSON is transmitted as UTF-8). With that in mind, I think the best you can do space-wise is base85 which represents four bytes as five characters. However, this is only a 7% improvement over base64, it's more expensive to compute, and implementations are less common than for base64 so it's probably not a win.

You could also simply map every input byte to the corresponding character in U+0000-U+00FF, then do the minimum encoding required by the JSON standard to pass those characters; the advantage here is that the required decoding is nil beyond builtin functions, but the space efficiency is bad -- a 105% expansion (if all input bytes are equally likely) vs. 25% for base85 or 33% for base64.

Final verdict: base64 wins, in my opinion, on the grounds that it's common, easy, and not bad enough to warrant replacement.

Sorry, answered my own question. It may not be the most correct or most elegant solution, but it works for me, and gives a pretty solid user experience. I looked into the code for ListView to see why the two behaviors are so different, and came across this from ListView.java:

    public void setItemsCanFocus(boolean itemsCanFocus) {
        mItemsCanFocus = itemsCanFocus;
        if (!itemsCanFocus) {
            setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
        }
    }

So, when calling setItemsCanFocus(false), it's also setting descendant focusability such that no child can get focus. This explains why I couldn't just toggle mItemsCanFocus in the ListView's OnItemSelectedListener -- because the ListView was then blocking focus to all children.

What I have now:

<ListView
    android:id="@android:id/list" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent"
    android:descendantFocusability="beforeDescendants"
    />

I use beforeDescendants because the selector will only be drawn when the ListView itself (not a child) has focus, so the default behavior needs to be that the ListView takes focus first and draws selectors.

Then in the OnItemSelectedListener, since I know which header view I want to override the selector (would take more work to dynamically determine if any given position contains a focusable view), I can change descendant focusability, and set focus on the EditText. And when I navigate out of that header, change it back it again.

public void onItemSelected(AdapterView<?> listView, View view, int position, long id)
{
    if (position == 1)
    {
        // listView.setItemsCanFocus(true);

        // Use afterDescendants, because I don't want the ListView to steal focus
        listView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
        myEditText.requestFocus();
    }
    else
    {
        if (!listView.isFocused())
        {
            // listView.setItemsCanFocus(false);

            // Use beforeDescendants so that the EditText doesn't re-take focus
            listView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
            listView.requestFocus();
        }
    }
}

public void onNothingSelected(AdapterView<?> listView)
{
    // This happens when you start scrolling, so we need to prevent it from staying
    // in the afterDescendants mode if the EditText was focused 
    listView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
}

Note the commented-out setItemsCanFocus calls. With those calls, I got the correct behavior, but setItemsCanFocus(false) caused focus to jump from the EditText, to another widget outside of the ListView, back to the ListView and displayed the selector on the next selected item, and that jumping focus was distracting. Removing the ItemsCanFocus change, and just toggling descendant focusability got me the desired behavior. All items draw the selector as normal, but when getting to the row with the EditText, it focused on the text field instead. Then when continuing out of that EditText, it started drawing the selector again.

As far as I can think bout it, there's only two ways you can do it. How can you know the user has finished writing a word? Either on focus lost, or clicking on an "ok" button. There's no way on my mind you can know the user pressed the last character...

So call onFocusChange(View v, boolean hasFocus) or add a button and a click listener to it.

Not sure if you have resolved it (and if I understand correctly), but here's my idea:

If parent receives myProp, and you want it to pass to child and watch it in child, then parent has to have copy of myProp (not reference).

Try this:

new Vue({
  el: '#app',
  data: {
    text: 'Hello'
  },
  components: {
    'parent': {
      props: ['myProp'],
      computed: {
        myInnerProp() { return myProp.clone(); } //eg. myProp.slice() for array
      }
    },
    'child': {
      props: ['myProp'],
      watch: {
        myProp(val, oldval) { now val will differ from oldval }
      }
    }
  }
}

and in html:

<child :my-prop="myInnerProp"></child>

actually you have to be very careful when working on complex collections in such situations (passing down few times)

You can also try recfromcsv() which can guess data types and return a properly formatted record array.

You can't achieve what you want with arrays. Use vectors instead, and read about the std::remove algorithm. Something like:

std::remove(array, array+5, 3)

will work on your array, but it will not shorten it (why -- because it's impossible). With vectors, it'd be something like

v.erase(std::remove(v.begin(), v.end(), 3), v.end())

Based on Roberts answer, here is my function. This works for me if the element or its parent have been faded out via jQuery, can either get inner or outer dimensions and also returns the offset values.

/edit1: rewrote the function. it's now smaller and can be called directly on the object

/edit2: the function will now insert the clone just after the original element instead of the body, making it possible for the clone to maintain inherited dimensions.

$.fn.getRealDimensions = function (outer) {
    var $this = $(this);
    if ($this.length == 0) {
        return false;
    }
    var $clone = $this.clone()
        .show()
        .css('visibility','hidden')
        .insertAfter($this);        
    var result = {
        width:      (outer) ? $clone.outerWidth() : $clone.innerWidth(), 
        height:     (outer) ? $clone.outerHeight() : $clone.innerHeight(), 
        offsetTop:  $clone.offset().top, 
        offsetLeft: $clone.offset().left
    };
    $clone.remove();
    return result;
}

var dimensions = $('.hidden').getRealDimensions();

The ensure the browser downloads a new version of the favicon and does not use a cached version you can add a dummy parameter to the favicon url:

<link rel="icon" type="image/x-icon" href="favicon.ico?any=param">

To check on elasticsearch cluster health you need to use

curl localhost:9200/_cat/health

More on the cat APIs here.

I usually use elasticsearch-head plugin to visualize that.

You can find it's github project here.

It's easy to install sudo $ES_HOME/bin/plugin -i mobz/elasticsearch-head and then you can open localhost:9200/_plugin/head/ in your web brower.

You should have something that looks like this :

You can trick MySQL into thinking you are actually specifying a primary key column. This allows you to "override" safe mode.

Assuming you have a table with an auto-incrementing numeric primary key, you could do the following:

DELETE FROM tbl WHERE id <> 0

ul {
  padding-left: 0;
  list-style-position: inside;
}

Explanation: The first property padding-left: 0 clears the default padding/spacing for the ul element while list-style-position: inside makes the dots/bullets of li aligned like a normal text.

So this code

<p>The ul element</p>
<ul>
asdfas
  <li>Coffee</li>
  <li>Tea</li>
  <li>Milk</li>
</ul>

without any CSS will give us this:

but if we add in the CSS give at the top, that will give us this:

Some Android phones contain Busybox. Was hard to find.

To see if busybox was around:

ls -lR / | grep busybox

If you know it's around. You need some read/write space. Try you flash drive, /sdcard

cd /sdcard
ls -lR / >lsoutput.txt

upload to your computer. Upload the file. Get some text editor. Search for busybox. Will see what directory the file was found in.

busybox find /sdcard -iname 'python*'

to make busybox easier to access, you could:

cd /sdcard
ln -s /where/ever/busybox/is  busybox
/sdcard/busybox find /sdcard -iname 'python*'

Or any other place you want. R

In my case, the problem was caused by not being logged in with Postman, so I opened a connection in another tab with a session cookie I took from the headers in my Chrome session.

Tested on Ideone.

import json
array = '{"fruits": ["apple", "banana", "orange"]}'
data  = json.loads(array)
fruits_list = data['fruits']
print fruits_list

An easy way to remember it is the way "canonical" is used in theological circles, canonical truth is the real truth so if two people find it they have found the same truth. Same with canonical instance. If you think you have found two of them (i.e. a.equals(b)) you really only have one (i.e. a == b). So equality implies identity in the case of canonical object.

Now for the comparison. You now have the choice of using a==b or a.equals(b), since they will produce the same answer in the case of canonical instance but a==b is comparison of the reference (the JVM can compare two numbers extremely rapidly as they are just two 32 bit patterns compared to a.equals(b) which is a method call and involves more overhead.

I typically reset my file input after capturing the selected files. No need to push a button, you have everything required in the $event object that you're passing to onChange:

onChange(event) {
  // Get your files
  const files: FileList = event.target.files;

  // Clear the input
  event.srcElement.value = null;
}

Different workflow, but the OP doesn't mention pushing a button is a requirement...

I just want to add what worked for me, I added height and width to both divs and used bootstrap to make it responsive

   <div class="col-lg-1 mapContainer">
       <div id="map"></div>
   </div>

   #map{
        height: 100%;
        width:100%;
   }
   .mapContainer{
        height:200px;
        width:100%
   }

in order for col-lg-1 to work add bootstrap reference located Here

It works for me:

>>> def pyth_test (x1, x2):
...     print x1 + x2
...
>>> pyth_test(1,2)
3

Make sure you define the function before you call it.

According to Ruskins answer and the comments here I came up with the following (recursive) solution:

public static T GetParentOfType<T>(this Control control) where T : class
{
    if (control?.Parent == null)
        return null;

    if (control.Parent is T parent)
        return parent;

    return GetParentOfType<T>(control.Parent);
}

if u want to set a bitmap object to image view here is simple two line`

Bitmap bitmap=BitmapFactory.decodeResource(getResources(),R.drawable.sample_drawable_image);
image.setImageBitmap(bitmap);

You JSON doesn't match your struct fields: E.g. "district" in JSON and "District" as the field.

Also: Your Item is a slice type but your JSON is a dict value. Do not mix this up. Slices decode from arrays.

The URL should point to your own custom filebrowser url you might have.

I have already done this in one of my projects, and I have posted a tutorial on this topic on my blog

http://www.mixedwaves.com/2010/02/integrating-fckeditor-filemanager-in-ckeditor/

The tutorial gives a step by step instructions about how to integrate the inbuilt FileBrowser of FCKEditor in CKEditor, if you don't want to make our own. Its pretty simple.

1.question answer-In your mobile having Developer Option in settings and enable that one. after In android studio project source file in bin--> apk file .just copy the apk file and paste in mobile memory in ur pc.. after all finished .you click that apk file in your mobile is automatically installed.

2.question answer-Your mobile is Samsung are just add Samsung Kies software in your pc..its helps to android code run in your mobile ...

If you specifically want to use an ad hoc wireless network, then Andy's answer seems to be your only option. However, if you just want to share your laptop's internet connection via Wi-fi using any means necessary, then you have at least two more options:

1. Use your laptop as a router to create a wifi hotspot using Virtual Router or Connectify. A nice set of instructions can be found here.
2. Use the Wi-fi Direct protocol which creates a direct connection between any devices that support it, although with Android devices support is limited* and with Windows the feature seems likely to be Windows 8 only.

*Some phones with Android 2.3 have proprietary OS extensions that enable Wi-fi Direct (mostly newer Samsung phones), but Android 4 should fully support this (source).

I FIGURED IT OUT. SIMPLE, EFFECTIVE NO jQUERY

We're going to to be using a hidden checkbox.
This example includes one "on click - off click 'hover / active' state"

--

To make content itself clickable:

HTML

<input type="checkbox" id="activate-div">
  <label for="activate-div">
   <div class="my-div">
      //MY DIV CONTENT
   </div>
  </label>

CSS

#activate-div{display:none}    

.my-div{background-color:#FFF} 

#activate-div:checked ~ label 
.my-div{background-color:#000}

To make button change content:

HTML

<input type="checkbox" id="activate-div">
   <div class="my-div">
      //MY DIV CONTENT
   </div>

<label for="activate-div">
   //MY BUTTON STUFF
</label>

CSS

#activate-div{display:none}

.my-div{background-color:#FFF} 

#activate-div:checked + 
.my-div{background-color:#000}

Hope it helps!!

You can specify an array in your HTML this way:

<input type="hidden" name="id[]" value="1"/>
<input type="hidden" name="id[]" value="2"/>
<input type="hidden" name="id[]" value="3"/>

This will result in this $_GET array in PHP:

array(
  'id' => array(
    0 => 1,
    1 => 2,
    2 => 3
  )
)

Of course, you can use any sort of HTML input, here. The important thing is that all inputs whose values you want in the 'id' array have the name id[].

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

What you are probably really wanting to do here is use the union operator like this:

(select ID from Logo where AccountID = 1 and Rendered = 'True')
  union
  (select ID from Design where AccountID = 1 and Rendered = 'True')
  order by ID limit 0, 51

Here's the docs for it https://dev.mysql.com/doc/refman/5.0/en/union.html

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

Making use of JavaScripts short-circuit evaluation. If el.shouldBeProcessed returns true, doSomeLengthyOperation

elementsCollection.forEach( el => 
  el.shouldBeProcessed && doSomeLengthyOperation()
);

This will also work

newData <- data*data

I think you can create empty numpy array like:

>>> import numpy as np
>>> empty_array= np.zeros(0)
>>> empty_array
array([], dtype=float64)
>>> empty_array.shape
(0,)

This format is useful when you want to append numpy array in the loop.

In chrome and firefox the methods above didn't work unless I used 'live' instead of 'bind'.

This worked for me:

$('img').live('contextmenu', function(e){
    return false;
});

The reason for this apparent performance discrepancy between categorical & binary cross entropy is what user xtof54 has already reported in his answer below, i.e.:

the accuracy computed with the Keras method evaluate is just plain wrong when using binary_crossentropy with more than 2 labels

I would like to elaborate more on this, demonstrate the actual underlying issue, explain it, and offer a remedy.

This behavior is not a bug; the underlying reason is a rather subtle & undocumented issue at how Keras actually guesses which accuracy to use, depending on the loss function you have selected, when you include simply metrics=['accuracy'] in your model compilation. In other words, while your first compilation option

model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])

is valid, your second one:

model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])

will not produce what you expect, but the reason is not the use of binary cross entropy (which, at least in principle, is an absolutely valid loss function).

Why is that? If you check the metrics source code, Keras does not define a single accuracy metric, but several different ones, among them binary_accuracy and categorical_accuracy. What happens under the hood is that, since you have selected binary cross entropy as your loss function and have not specified a particular accuracy metric, Keras (wrongly...) infers that you are interested in the binary_accuracy, and this is what it returns - while in fact you are interested in the categorical_accuracy.

Let's verify that this is the case, using the MNIST CNN example in Keras, with the following modification:

model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])  # WRONG way

model.fit(x_train, y_train,
          batch_size=batch_size,
          epochs=2,  # only 2 epochs, for demonstration purposes
          verbose=1,
          validation_data=(x_test, y_test))

# Keras reported accuracy:
score = model.evaluate(x_test, y_test, verbose=0) 
score[1]
# 0.9975801164627075

# Actual accuracy calculated manually:
import numpy as np
y_pred = model.predict(x_test)
acc = sum([np.argmax(y_test[i])==np.argmax(y_pred[i]) for i in range(10000)])/10000
acc
# 0.98780000000000001

score[1]==acc
# False    

To remedy this, i.e. to use indeed binary cross entropy as your loss function (as I said, nothing wrong with this, at least in principle) while still getting the categorical accuracy required by the problem at hand, you should ask explicitly for categorical_accuracy in the model compilation as follows:

from keras.metrics import categorical_accuracy
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=[categorical_accuracy])

In the MNIST example, after training, scoring, and predicting the test set as I show above, the two metrics now are the same, as they should be:

# Keras reported accuracy:
score = model.evaluate(x_test, y_test, verbose=0) 
score[1]
# 0.98580000000000001

# Actual accuracy calculated manually:
y_pred = model.predict(x_test)
acc = sum([np.argmax(y_test[i])==np.argmax(y_pred[i]) for i in range(10000)])/10000
acc
# 0.98580000000000001

score[1]==acc
# True    

System setup:

Python version 3.5.3
Tensorflow version 1.2.1
Keras version 2.0.4

UPDATE: After my post, I discovered that this issue had already been identified in this answer.

compareTo() is from the Comparable interface.

compare() is from the Comparator interface.

Both methods do the same thing, but each interface is used in a slightly different context.

The Comparable interface is used to impose a natural ordering on the objects of the implementing class. The compareTo() method is called the natural comparison method. The Comparator interface is used to impose a total ordering on the objects of the implementing class. For more information, see the links for exactly when to use each interface.

You should take a look at the new Spatial data-types that were introduced in SQL Server 2008. They are specifically designed this kind of task and make indexing and querying the data much easier and more efficient.

By Changing The DbContext As Below;

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
    }

Just adding in OnModelCreating method call to base.OnModelCreating(modelBuilder); and it becomes fine. I am using EF6.

In particular it wasn't too difficult to use abego TreeLayout to produce results shown below with the default settings.

If you try that tool, note this caveat: It prints children in the order they were added. For a BST where left vs right matters I found this library to be inappropriate without modification.

Also, the method to add children simply takes a parent and child node as parameters. (So to process a bunch of nodes, you must take the first one separately to create a root.)

I ended up using this solution above, modifying it to take in the type <Node> so as to have access to Node's left and right (children).

When you are sure your script is perfectly working, you can get rid of warning and notices like this: Put this line at the beginning of your PHP script:

error_reporting(E_ERROR);

Before that, when working on your script, I would advise you to properly debug your script so that all notice or warning disappear one by one.

So you should first set it as verbose as possible with:

error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

UPDATE: how to log errors instead of displaying them

As suggested in the comments, the better solution is to log errors into a file so only the PHP developer sees the error messages, not the users.

A possible implementation is via the .htaccess file, useful if you don't have access to the php.ini file (source).

# Suppress PHP errors
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

# Enable PHP error logging
php_flag  log_errors on
php_value error_log  /home/path/public_html/domain/PHP_errors.log

# Prevent access to PHP error log
<Files PHP_errors.log>
 Order allow,deny
 Deny from all
 Satisfy All
</Files>

To style the output to your preferred pretty format, see the man page for git-log.

Example:

git log --pretty=format:"%h; author: %cn; date: %ci; subject:%s" tagA...tagB

Another approach is to first do a searchType: 'count', then and then do a normal search with size set to results.count.

The advantage here is it avoids depending on a magic number for UPPER_BOUND as suggested in this similar SO question, and avoids the extra overhead of building too large of a priority queue that Shay Banon describes here. It also lets you keep your results sorted, unlike scan.

The biggest disadvantage is that it requires two requests. Depending on your circumstance, this may be acceptable.

If you make all the properties animated the same, you can set each separately which will allow you to not repeat the code.

 transition: all 2s;
 transition-property: color, text-shadow;

There is more about it here: CSS transition shorthand with multiple properties?

I would avoid using the property all (transition-property overwrites 'all'), since you could end up with unwanted behavior and unexpected performance hits.

Use innerText/textContent:

  var el = document.getElementById('*spaM4');
  console.log(el.innerText || el.textContent);

I wrote a little post to help out with this, you can read more here https://timber.io/snippets/asynchronously-load-a-script-in-the-browser-with-javascript/, but I've attached the helper class below. It will automatically wait for a script to load and return a specified window attribute once it does.

export default class ScriptLoader {
  constructor (options) {
    const { src, global, protocol = document.location.protocol } = options
    this.src = src
    this.global = global
    this.protocol = protocol
    this.isLoaded = false
  }

  loadScript () {
    return new Promise((resolve, reject) => {
      // Create script element and set attributes
      const script = document.createElement('script')
      script.type = 'text/javascript'
      script.async = true
      script.src = `${this.protocol}//${this.src}`

      // Append the script to the DOM
      const el = document.getElementsByTagName('script')[0]
      el.parentNode.insertBefore(script, el)

      // Resolve the promise once the script is loaded
      script.addEventListener('load', () => {
        this.isLoaded = true
        resolve(script)
      })

      // Catch any errors while loading the script
      script.addEventListener('error', () => {
        reject(new Error(`${this.src} failed to load.`))
      })
    })
  }

  load () {
    return new Promise(async (resolve, reject) => {
      if (!this.isLoaded) {
        try {
          await this.loadScript()
          resolve(window[this.global])
        } catch (e) {
          reject(e)
        }
      } else {
        resolve(window[this.global])
      }
    })
  }
}

Usage is like this:

const loader = new Loader({
    src: 'cdn.segment.com/analytics.js',
    global: 'Segment',
})

// scriptToLoad will now be a reference to `window.Segment`
const scriptToLoad = await loader.load()

Assuming that you are using UTF-8 encoding:

string convert = "This is the string to be converted";

// From string to byte array
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);

// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);

You can use this utility class -

public class DateUtils
{
    public static final long SECOND_IN_MILLIS = 1000;
    public static final long MINUTE_IN_MILLIS = SECOND_IN_MILLIS * 60;
    public static final long HOUR_IN_MILLIS = MINUTE_IN_MILLIS * 60;
    public static final long DAY_IN_MILLIS = HOUR_IN_MILLIS * 24;
    public static final long WEEK_IN_MILLIS = DAY_IN_MILLIS * 7;
}

If you are working on Android framework then just import it (also named DateUtils) under package android.text.format

'\r' is the carriage return character. The main times it would be useful are:

1. When reading text in binary mode, or which may come from a foreign OS, you'll find (and probably want to discard) it due to CR/LF line-endings from Windows-format text files.

2. When writing to an interactive terminal on stdout or stderr, '\r' can be used to move the cursor back to the beginning of the line, to overwrite it with new contents. This makes a nice primitive progress indicator.

The example code in your post is definitely a wrong way to use '\r'. It assumes a carriage return will precede the newline character at the end of a line entered, which is non-portable and only true on Windows. Instead the code should look for '\n' (newline), and discard any carriage return it finds before the newline. Or, it could use text mode and have the C library handle the translation (but text mode is ugly and probably should not be used).

You can use the IndexOf method and the Substring method like so:

string output = input.Substring(input.IndexOf('.') + 1);

The above doesn't have error handling, so if a period doesn't exist in the input string, it will present problems.

vector<string> getseq(char * db_file)

And if you want to print it on main() you should do it in a loop.

int main() {
     vector<string> str_vec = getseq(argv[1]);
     for(vector<string>::iterator it = str_vec.begin(); it != str_vec.end(); it++) {
         cout << *it << endl;
     }
}

I think the problem is with the datatype of the data you are passing Caused by: java.sql.SQLException: Invalid column type: 1111 check the datatypes you pass with the actual column datatypes may be there can be some mismatch or some constraint violation with null

It's basically the same as Darin Dimitrov's but it shows how you could use it do dynamically create and store functions and arguments. I hope it's useful for you :)

var argsContainer = ['hello', 'you', 'there'];_x000D_
var functionsContainer = [];_x000D_
_x000D_
for (var i = 0; i < argsContainer.length; i++) {_x000D_
var currentArg = argsContainer[i]; _x000D_
_x000D_
  functionsContainer.push(function(currentArg){_x000D_
    console.log(currentArg);_x000D_
  });_x000D_
};_x000D_
_x000D_
for (var i = 0; i < functionsContainer.length; i++) {_x000D_
  functionsContainer[i](argsContainer[i]);_x000D_
}

From the docs on angular.element:

find() - Limited to lookups by tag name

So if you're not using jQuery with Angular, but relying upon its jqlite implementation, you can't do elm.find('#someid').

You do have access to children(), contents(), and data() implementations, so you can usually find a way around it.

I think you could do:

$('#google_translate_element').find('*').each(function(){
    $(this).unbind('click');
});

but it would cause a lot of overhead

Python 3.7 introduces 6 new time functions with nanosecond resolution, for example instead of time.time() you can use time.time_ns() to avoid floating point imprecision issues:

import time
print(time.time())
# 1522915698.3436284
print(time.time_ns())
# 1522915698343660458

These 6 functions are described in PEP 564:

time.clock_gettime_ns(clock_id)

time.clock_settime_ns(clock_id, time:int)

time.monotonic_ns()

time.perf_counter_ns()

time.process_time_ns()

time.time_ns()

These functions are similar to the version without the _ns suffix, but return a number of nanoseconds as a Python int.

int i;
string whatever;

//Best since no exception raised
int.TryParse(whatever, out i);

//Better use try catch on this one
i = Convert.ToInt32(whatever);

What is a LATERAL join?

The feature was introduced with PostgreSQL 9.3.
Quoting the manual:

Subqueries appearing in FROM can be preceded by the key word LATERAL. This allows them to reference columns provided by preceding FROM items. (Without LATERAL, each subquery is evaluated independently and so cannot cross-reference any other FROM item.)

Table functions appearing in FROM can also be preceded by the key word LATERAL, but for functions the key word is optional; the function's arguments can contain references to columns provided by preceding FROM items in any case.

Basic code examples are given there.

More like a correlated subquery

A LATERAL join is more like a correlated subquery, not a plain subquery, in that expressions to the right of a LATERAL join are evaluated once for each row left of it - just like a correlated subquery - while a plain subquery (table expression) is evaluated once only. (The query planner has ways to optimize performance for either, though.)
Related answer with code examples for both side by side, solving the same problem:

• Optimize GROUP BY query to retrieve latest row per user

For returning more than one column, a LATERAL join is typically simpler, cleaner and faster.
Also, remember that the equivalent of a correlated subquery is LEFT JOIN LATERAL ... ON true:

• Call a set-returning function with an array argument multiple times

Things a subquery can't do

There are things that a LATERAL join can do, but a (correlated) subquery cannot (easily). A correlated subquery can only return a single value, not multiple columns and not multiple rows - with the exception of bare function calls (which multiply result rows if they return multiple rows). But even certain set-returning functions are only allowed in the FROM clause. Like unnest() with multiple parameters in Postgres 9.4 or later. The manual:

This is only allowed in the FROM clause;

So this works, but cannot (easily) be replaced with a subquery:

CREATE TABLE tbl (a1 int[], a2 int[]);
SELECT * FROM tbl, unnest(a1, a2) u(elem1, elem2);  -- implicit LATERAL

The comma (,) in the FROM clause is short notation for CROSS JOIN.
LATERAL is assumed automatically for table functions.
About the special case of UNNEST( array_expression [, ... ] ):

• How do you declare a set-returning-function to only be allowed in the FROM clause?

Set-returning functions in the SELECT list

You can also use set-returning functions like unnest() in the SELECT list directly. This used to exhibit surprising behavior with more than one such function in the same SELECT list up to Postgres 9.6. But it has finally been sanitized with Postgres 10 and is a valid alternative now (even if not standard SQL). See:

• What is the expected behaviour for multiple set-returning functions in SELECT clause?

Building on above example:

SELECT *, unnest(a1) AS elem1, unnest(a2) AS elem2
FROM   tbl;

Comparison:

dbfiddle for pg 9.6 here
dbfiddle for pg 10 here

Clarify misinformation

The manual:

For the INNER and OUTER join types, a join condition must be specified, namely exactly one of NATURAL, ON join_condition, or USING (join_column [, ...]). See below for the meaning.
For CROSS JOIN, none of these clauses can appear.

So these two queries are valid (even if not particularly useful):

SELECT *
FROM   tbl t
LEFT   JOIN LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t ON TRUE;

SELECT *
FROM   tbl t, LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t;

While this one is not:

SELECT *
FROM   tbl t
LEFT   JOIN LATERAL (SELECT * FROM b WHERE b.t_id = t.t_id) t;

That's why Andomar's code example is correct (the CROSS JOIN does not require a join condition) and Attila's is was not.

If you need to retrieve more columns other than columns which are in group by then you can consider below query. Check it once whether it is performing well or not.

SELECT 
a.[CUSTOMER ID], 
a.[NAME], 
(select SUM(b.[AMOUNT]) from INV_DATA b
where b.[CUSTOMER ID] = a.[CUSTOMER ID]
GROUP BY b.[CUSTOMER ID]) AS [TOTAL AMOUNT]
FROM RES_DATA a

I'm not a mathematician or cryptician, so here's an outside observation in layman's terms (no fancy equations, sorry).

This whole thread is filled with explanations about HOW primes are used in cryptography, it's hard to find anyone in this thread explaining in an easy way WHY primes are used ... most likely because everyone takes that knowledge for granted.

Only looking at the problem from the outside can generate a reaction like; but if they use the sums of two primes, why not create a list of all possible sums any two primes can generate?

On this site there's a list of 455,042,511 primes, where the highest primes is 9,987,500,000 (10 digits).

The largest known prime (as of feb 2015) is 2 to the power of 257,885,161 - 1 which is 17,425,170 digits.

This means that there's no point keeping a list of all the known primes and much less all their possible sums. It's easier to take a number and check if it's a prime.

Calculating big primes in itself is a monumental task, so reverse calculating two primes that has been multiplied with each other both cryptographers and mathematicians would say is hard enough ... today.

In Android Studio you don't need the plug in. On A Mac just open Android Studio -> click Android Studio in the top bar -> click Prefrences -> find File and Code Templates in the list -> select includes -> build it and will be persistent in all your project

Or just call mysql command with --version option.

mysql --version

I think when you define a function with "var foo = function() {...};", the function is only defined after that line. In other words, try this:

var replaceHtmlEntites = (function() {
  var translate_re = /&(nbsp|amp|quot|lt|gt);/g;
  var translate = {
    "nbsp": " ",
    "amp" : "&",
    "quot": "\"",
    "lt"  : "<",
    "gt"  : ">"
  };
  return function(s) {
    return ( s.replace(translate_re, function(match, entity) {
      return translate[entity];
    }) );
  }
})();

var cleanText = text.replace(/^\xa0*([^\xa0]*)\xa0*$/g,"");
cleanText = replaceHtmlEntities(text);

Edit: Also, only use "var" the first time you declare a variable (you're using it twice on the cleanText variable).

Edit 2: The problem is the spelling of the function name. You have "var replaceHtmlEntites =". It should be "var replaceHtmlEntities ="

You can use CSS3 'transform':

CSS:

.popup-bck{
  background-color: rgba(102, 102, 102, .5);
  position: fixed;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: 10;
}
.popup-content-box{
  background-color: white;
  position: fixed;
  top: 50%;
  left: 50%;
  z-index: 11;
-webkit-transform: translate(-50%, -50%);
-moz-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
-o-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}

HTML:

<div class="popup-bck"></div>
<div class="popup-content-box">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. 
</div>

*so you don't have to use margin-left: -width/2 px;

You have to read the API carefully for this methods. Sometimes you can get confused very easily.

It is either:

if (B.class.isInstance(view))

API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)

or:

if (B.class.isAssignableFrom(view.getClass()))

API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter

or (without reflection and the recommended one):

if (view instanceof B)

I was solving same problem recently. I was designing a write cmdlet for my Subtitle module. I had six different user stories:

• Subtitle only
• Subtitle and path (original file name is used)
• Subtitle and new file name (original path is used)
• Subtitle and name suffix is used (original path and modified name is used).
• Subtile, new path and new file name is is used.
• Subtitle, new path and suffix is used.

I end up in the big frustration because I though that 4 parameters will be enough. Like most of the times, the frustration was pointless because it was my fault. I didn't know enough about parameter sets.

After some research in documentation, I realized where is the problem. With knowledge how the parameter sets should be used, I developed a general and simple approach how to solve this problem. A pencil and a sheet of paper is required but a spreadsheet editor is better:

1. Write down all intended ways how the cmdlet should be used => user stories.
2. Keep adding parameters with meaningful names and mark the use of the parameters until you have a unique collection set => no repetitive combination of parameters.
3. Implement parameter sets into your code.
4. Prepare tests for all possible user stories.
5. Run tests (big surprise, right?). IDEs doesn't checks parameter sets collision, tests could save lots of trouble later one.

Example:

The practical example could be seen over here.

BTW: The parameter uniqueness within parameter sets is the reason why the ParameterSetName property doesn't support [String[]]. It doesn't really make any sense.

Make sure file name "Dockerfile" is not saved with any extension. Just create a file without any extension.

And make sure Dockerfile is in same directory from where you are trying to building docker image.

I have spent a lot of time looking for solution for this. And finally managed to do this. Don't forget to upvote @Jason Robinson answer because my is based on his.

So first thing, you sholuld know that since Android 7.0 we have to use FileProvider and something called ContentUri, otherwise you will get an annoying error trying to invoke your Intent. This is sample code:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, getUriFromPath(context, "[Your path to save image]"));
startActivityForResult(intent, CAPTURE_IMAGE_RESULT);

Method getUriFromPath(Context, String) basis on user version of Android create FileUri (file://...) or ContentUri (content://...) and there it is:

public Uri getUriFromPath(Context context, String destination) {
    File file =  new File(destination);

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
        return FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
    } else {
        return Uri.fromFile(file);
    }
}

After onActivityResult you can catch that uri where image is saved by camera, but now you have to detect camera rotation, here we will use moddified @Jason Robinson answer:

First we need to create ExifInterface based on Uri

@Nullable
public ExifInterface getExifInterface(Context context, Uri uri) {
    try {
        String path = uri.toString();
        if (path.startsWith("file://")) {
            return new ExifInterface(path);
        }
        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            if (path.startsWith("content://")) {
                InputStream inputStream = context.getContentResolver().openInputStream(uri);
                return new ExifInterface(inputStream);
            }
        }
    }
    catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

Above code can be simplified, but i want to show everything. So from FileUri we can create ExifInterface based on String path, but from ContentUri we can't, Android doesn't support that.

In that case we have to use other constructor based on InputStream. Remember this constructor isn't available by default, you have to add additional library:

compile "com.android.support:exifinterface:XX.X.X"

Now we can use getExifInterface method to get our angle:

public float getExifAngle(Context context, Uri uri) {
    try {
        ExifInterface exifInterface = getExifInterface(context, uri);
        if(exifInterface == null) {
            return -1f;
        }

        int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION,
                ExifInterface.ORIENTATION_UNDEFINED);

        switch (orientation) {
            case ExifInterface.ORIENTATION_ROTATE_90:
                return 90f;
            case ExifInterface.ORIENTATION_ROTATE_180:
                return 180f;
            case ExifInterface.ORIENTATION_ROTATE_270:
                return 270f;
            case ExifInterface.ORIENTATION_NORMAL:
                return 0f;
            case ExifInterface.ORIENTATION_UNDEFINED:
                return -1f;
            default:
                return -1f;
        }
    }
    catch (Exception e) {
        e.printStackTrace();
        return -1f;
    }
}

Now you have Angle to properly rotate you image :).

SQL Server / MS Access Syntax:

SELECT TOP 1 * FROM table_name ORDER BY RAND()

MySQL Syntax:

SELECT * FROM table_name ORDER BY RAND() LIMIT 1

// To see global variable is enabled or not and location of query log    
SHOW VARIABLES like 'general%';
// Set query log on 
SET GLOBAL general_log = ON; 

You don't have to use Tomcat installation as a server location. It is much easier just to copy the files in the ROOT folder.

Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.8\webapps, R-click on the ROOT folder and copy it. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or ../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder, R-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.

You can either:

• Use XmlSerializer class
• Use XmlDocument class

There is actually no difference as both require 1 click:

• Eclipse: manual Save, auto-compile.
• IntelliJ: auto Save, manual compile.

Simplest solution is just to get used to it. Because when you spend most of your daytime in your IDE, then better have fast habits in one than slow habits in several of them.

with jQuery :
html :

<form method="POST" name="myform" action="index.php?action=contact_agent&agent_id="  onsubmit="SetData()">
  <select name="agent" id="agent">
    <option value="1">Agent Homer</option>
    <option value="2">Agent Lenny</option>
    <option value="3">Agent Carl</option>
  </select>
</form>

jQuery :

$('form').submit(function(){
   $(this).attr('action',$(this).attr('action')+$('#agent').val());
   $(this).submit();
});

javascript :

function SetData(){
   var select = document.getElementById('agent');
   var agent_id = select.options[select.selectedIndex].value;
   document.myform.action = "index.php?action=contact_agent&agent_id="+agent_id ; # or .getAttribute('action')
   myform.submit();
}

Solution : SpreadsheetApp.getActiveSheet().getRange('F2').setValue('hello')

Explanation :

Setting value in a cell in spreadsheet to which script is attached

SpreadsheetApp.getActiveSpreadsheet().getSheetByName(SHEET_NAME).getRange(RANGE).setValue(VALUE);

Setting value in a cell in sheet which is open currently and to which script is attached

SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange(RANGE).setValue(VALUE);

Setting value in a cell in some spreadsheet to which script is NOT attached (Destination sheet name known)

SpreadsheetApp.openById(SHEET_ID).getSheetByName(SHEET_NAME).getRange(RANGE).setValue(VALUE);

Setting value in a cell in some spreadsheet to which script is NOT attached (Destination sheet position known)

SpreadsheetApp.openById(SHEET_ID).getSheets()[POSITION].getRange(RANGE).setValue(VALUE);

These are constants, you must define them yourself

SHEET_ID

SHEET_NAME

POSITION

VALUE

RANGE

By script attached to a sheet I mean that script is residing in the script editor of that sheet. Not attached means not residing in the script editor of that sheet. It can be in any other place.

I guess it depends on what you are processing. If you are calculating the FFT over a large duration you might find that it does take a while depending on how many frequency points you are wanting. However, in most cases for audio it is considered non-stationary (that is the signals mean and variance changes to much over time), so taking one large FFT (Periodogram PSD estimate) is not an accurate representation. Alternatively you could use Short-time Fourier transform, whereby you break the signal up into smaller frames and calculate the FFT. The frame size varies depending on how quickly the statistics change, for speech it is usually 20-40ms, for music I assume it is slightly higher.

This method is good if you are sampling from the microphone, because it allows you to buffer each frame at a time, calculate the fft and give what the user feels is "real time" interaction. Because 20ms is quick, because we can't really perceive a time difference that small.

I developed a small bench mark to test the difference between FFTW and KissFFT c-libraries on a speech signal. Yes FFTW is highly optimised, but when you are taking only short-frames, updating the data for the user, and using only a small fft size, they are both very similar. Here is an example on how to implement the KissFFT libraries in Android using LibGdx by badlogic games. I implemented this library using overlapping frames in an Android App I developed a few months ago called Speech Enhancement for Android.

For me, I was receiving this error when connecting to the new IP Address I had configured FileZilla to bind to and saved the configuration. After trying all of the other answers unsuccessfully, I decided to connect to the old IP Address to see what came up; lo and behold it responded.

I restarted the FileZilla Windows Service and it immediately came back listening on the correct IP. Pretty elementary, but it cost me some time today as a noob to FZ.

Hopefully this helps someone out in the same predicament.

Seems like the only way to get decimal in a pretty (for me) form requires some ridiculous code.

The only solution I got so far:

CASE WHEN xy>0 and xy<1 then '0' || to_char(xy) else to_char(xy)

xy is a decimal.

xy             query result
0.8            0.8  --not sth like .80
10             10  --not sth like 10.00

Here's a comprehensive yet non-exhaustive list of examples of list operations and whether or not they are thread safe. Hoping to get an answer regarding the obj in a_list language construct here.

This is an option:

dbContext.Entry(entity).State = EntityState.Detached;

There is no cross-browser way of styling option elements, certainly not to the extent of your second screenshot. You might be able to make them bold, and set the font-size, but that will be about it...

The problem is likely you try to register a 32-bit library with 64-bit version of regsvr32. See this KB article - you need to run regsvr32 from windows\SysWOW64 for 32-bit libraries.

Here is the simple solution by StreamEx:

StreamEx.of(list).groupingBy(Function.identity(), MoreCollectors.countingInt());

This has the advantage of reducing the Java stream boilerplate code: collect(Collectors.

Using a decorator for measuring execution time for functions can be handy. There is an example at http://www.zopyx.com/blog/a-python-decorator-for-measuring-the-execution-time-of-methods.

Below I've shamelessly pasted the code from the site mentioned above so that the example exists at SO in case the site is wiped off the net.

import time                                                

def timeit(method):

    def timed(*args, **kw):
        ts = time.time()
        result = method(*args, **kw)
        te = time.time()

        print '%r (%r, %r) %2.2f sec' % \
              (method.__name__, args, kw, te-ts)
        return result

    return timed

class Foo(object):

    @timeit
    def foo(self, a=2, b=3):

To just add a custom content to the current UserAgent value, do the following:

1 - Get the user agent value from a NEW WEBVIEW

2 - Append the custom content to it

3 - Save the new value in a dictionary with the key UserAgent

4 - Save the dictionary in standardUserDefaults.

See the exemple below:

NSString *userAgentP1 = [[[UIWebView alloc] init] stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];
NSString *userAgentP2 = @"My_custom_value";
NSString *userAgent = [NSString stringWithFormat:@"%@ %@", userAgentP1, userAgentP2];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:userAgent, @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];

First:

By convention, in Python world, the shortcut for numpy is np, so:

In [1]: import numpy as np

In [2]: a = np.array([[1,2],[3,4]])

Second:

In Numpy, dimension, axis/axes, shape are related and sometimes similar concepts:

dimension

In Mathematics/Physics, dimension or dimensionality is informally defined as the minimum number of coordinates needed to specify any point within a space. But in Numpy, according to the numpy doc, it's the same as axis/axes:

In Numpy dimensions are called axes. The number of axes is rank.

In [3]: a.ndim  # num of dimensions/axes, *Mathematics definition of dimension*
Out[3]: 2

axis/axes

the nth coordinate to index an array in Numpy. And multidimensional arrays can have one index per axis.

In [4]: a[1,0]  # to index `a`, we specific 1 at the first axis and 0 at the second axis.
Out[4]: 3  # which results in 3 (locate at the row 1 and column 0, 0-based index)

shape

describes how many data (or the range) along each available axis.

In [5]: a.shape
Out[5]: (2, 2)  # both the first and second axis have 2 (columns/rows/pages/blocks/...) data

My approach was, but I can't guarantee that this is the fastest solution.

df = pd.DataFrame(columns=["firstname", "lastname"])
df = df.append({
     "firstname": "John",
     "lastname":  "Johny"
      }, ignore_index=True)

I would suggest instead of trying to extract the HTML from the WebView, you extract the HTML from the URL. By this, I mean using a third party library such as JSoup to traverse the HTML for you. The following code will get the HTML from a specific URL for you

public static String getHtml(String url) throws ClientProtocolException, IOException {
        HttpClient httpClient = new DefaultHttpClient();
        HttpContext localContext = new BasicHttpContext();
        HttpGet httpGet = new HttpGet(url);
        HttpResponse response = httpClient.execute(httpGet, localContext);
        String result = "";

        BufferedReader reader = new BufferedReader(
            new InputStreamReader(
                response.getEntity().getContent()
            )
        );

        String line = null;
        while ((line = reader.readLine()) != null){
            result += line + "\n";
        }
        return result;
    }

Two different kinds of parameters can be adjusted during the training of an ANN, the weights and the value in the activation functions. This is impractical and it would be easier if only one of the parameters should be adjusted. To cope with this problem a bias neuron is invented. The bias neuron lies in one layer, is connected to all the neurons in the next layer, but none in the previous layer and it always emits 1. Since the bias neuron emits 1 the weights, connected to the bias neuron, are added directly to the combined sum of the other weights (equation 2.1), just like the t value in the activation functions.1

The reason it's impractical is because you're simultaneously adjusting the weight and the value, so any change to the weight can neutralize the change to the value that was useful for a previous data instance... adding a bias neuron without a changing value allows you to control the behavior of the layer.

Furthermore the bias allows you to use a single neural net to represent similar cases. Consider the AND boolean function represented by the following neural network:

_{(source: aihorizon.com)}

• w0 corresponds to b.
• w1 corresponds to x1.
• w2 corresponds to x2.

A single perceptron can be used to represent many boolean functions.

For example, if we assume boolean values of 1 (true) and -1 (false), then one way to use a two-input perceptron to implement the AND function is to set the weights w0 = -3, and w1 = w2 = .5. This perceptron can be made to represent the OR function instead by altering the threshold to w0 = -.3. In fact, AND and OR can be viewed as special cases of m-of-n functions: that is, functions where at least m of the n inputs to the perceptron must be true. The OR function corresponds to m = 1 and the AND function to m = n. Any m-of-n function is easily represented using a perceptron by setting all input weights to the same value (e.g., 0.5) and then setting the threshold w0 accordingly.

Perceptrons can represent all of the primitive boolean functions AND, OR, NAND ( 1 AND), and NOR ( 1 OR). Machine Learning- Tom Mitchell)

The threshold is the bias and w0 is the weight associated with the bias/threshold neuron.

Introduction

Basically, if there is a need to display a sorted collection, please consider using the CollectionViewSource class: assign ("bind") its Source property to the source collection — an instance of the ObservableCollection<T> class.

The idea is that CollectionViewSource class provides an instance of the CollectionView class. This is kind of "projection" of the original (source) collection, but with applied sorting, filtering, etc.

References:

• How to: Sort and Group Data Using a View in XAML.
• WPF’s CollectionViewSource.

Live Shaping

WPF 4.5 introduces "Live Shaping" feature for CollectionViewSource.

References:

• WPF 4.5 New Feature: Live Shaping.
• CollectionViewSource.IsLiveSorting Property.
• Repositioning data as the data's values change (Live shaping).

Solution

If there still a need to sort an instance of the ObservableCollection<T> class, here is how it can be done. The ObservableCollection<T> class itself does not have sort method. But, the collection could be re-created to have items sorted:

// Animals property setter must raise "property changed" event to notify binding clients.
// See INotifyPropertyChanged interface for details.
Animals = new ObservableCollection<string>
    {
        "Cat", "Dog", "Bear", "Lion", "Mouse",
        "Horse", "Rat", "Elephant", "Kangaroo",
        "Lizard", "Snake", "Frog", "Fish",
        "Butterfly", "Human", "Cow", "Bumble Bee"
    };
...
Animals = new ObservableCollection<string>(Animals.OrderBy(i => i));

Additional details

Please note that OrderBy() and OrderByDescending() methods (as other LINQ–extension methods) do not modify the source collection! They instead create a new sequence (i.e. a new instance of the class that implements IEnumerable<T> interface). Thus, it is necessary to re-create the collection.

Use the JavaScript RegExp object constructor.

var re = new RegExp("\\w+");
re.test("hello");

You can pass flags as a second string argument to the constructor. See the documentation for details.

I am currently using PDFBox which has good support for graphic output. There is good support for extracting the vector strokes and also for managing fonts. There are some good tools for trying it out (e.g. PDFReader will display as Java Graphics2D). You can intercept the graphics tool with an SVG tool like Batik (I do this and it gives good capture).

There is no simple way to convert all PDF to SVG - it depends on the strategy and tools used to create the PDFs. Some text is converted to vectors and cannot be easily reconstructed - you have to install vector fonts and look them up.

UPDATE: I have now developed this into a package PDF2SVG which does not use Batik any more:

which has been tested on a range of PDFs. It produces SVG output consisting of

• characters as one <svg:text> per character
• paths as <svg:path>
• images as <svg:image>

Later packages will (hopefully) convert the characters to running text and the paths to higher-level graphics objects

UPDATE: We can now re-create running text from the SVG characters. We've also converted diagrams to domain-specific XML (e.g. chemical spectra). See https://bitbucket.org/petermr/svg2xml-dev. It's still in Alpha, but is moving at a useful speed. Anyone can join in!

UPDATE. (@Tim Kelty) We are continuing to work on PDF2SVG and also downstream tools that do (limited) Java OCR and creation of higher-level graphics primitives (arrows, boxes, etc.) See https://bitbucket.org/petermr/imageanalysis https://bitbucket.org/petermr/diagramanalyzer https://bitbucket.org/petermr/norma and https://bitbucket.org/petermr/ami-core . This is a funded project to capture 100 million facts from the scientific literature (contentmine.org) much of which is PDF.
