I'd really recommend Scrapy.

Quote from a deleted answer:

• Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
• Scrapy has better and fastest support for parsing (x)html on top of libxml2.
• Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
• Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.

This code below works for me. I always use only single quotes, and it works fine. I suggest you should use only single quotes or only double quotes, but not mixed up.

$.ajax({
    url: 'YourRestEndPoint',
    headers: {
        'Authorization':'Basic xxxxxxxxxxxxx',
        'X-CSRF-TOKEN':'xxxxxxxxxxxxxxxxxxxx',
        'Content-Type':'application/json'
    },
    method: 'POST',
    dataType: 'json',
    data: YourData,
    success: function(data){
      console.log('succes: '+data);
    }
  });

This work for me

<%= f.select :status, [["Single", "single"], ["Married", "married"], ["Engaged", "engaged"], ["In a Relationship", "relationship"]], {}, {class: "form-control"} %>

Found a strange behaviour about this hidden value () and we can't make it to work.

After playing around we found the best way is just defined the value in controller itself after the form scope.

.controller('AddController', [$scope, $http, $state, $stateParams, function($scope, $http, $state, $stateParams) {

    $scope.routineForm = {};
    $scope.routineForm.hiddenfield1 = "whatever_value_you_pass_on";

    $scope.sendData = function {

// JSON http post action to API 
}

}])

The answer I was looking for is at https://unix.stackexchange.com/a/9557/114862.

Using the -c flag when the local file is of greater or equal size to the server version will avoid re-downloading.

Use order function:

set.seed(1)
DF <- data.frame(ID= sample(letters[1:26], 15, TRUE),
                 num = sample(1:100, 15, TRUE),
                 random = rnorm(15),
                 stringsAsFactors=FALSE)
DF[order(DF[,'ID']), ]
   ID num      random
10  b  27  0.61982575
12  e   2 -0.15579551
5   f  78  0.59390132
11  f  39 -0.05612874
1   g  50 -0.04493361
2   j  72 -0.01619026
14  j  87 -0.47815006
3   o 100  0.94383621
9   q  13 -1.98935170
8   r  66  0.07456498
13  r  39 -1.47075238
15  u  35  0.41794156
4   x  39  0.82122120
6   x  94  0.91897737
7   y  22  0.78213630

Another solution would be using orderByfunction from doBy package:

> library(doBy)
> orderBy(~ID, DF)

Simple answer in Python: If you need to create a large real text file I just used a simple while loop and was able to create a 5 GB file in about 20 seconds. I know it's crude, but it is fast enough.

outfile = open("outfile.log", "a+")

def write(outfile):
    outfile.write("hello world hello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello worldhello world"+"\n")
    return

i=0
while i < 1000000:
    write(outfile)
    i += 1
outfile.close()

You didn't join the table in your query.

Your original query will always return nothing unless there are no records at all in eotm_dyn, in which case it will return everything.

Assuming these tables should be joined on employeeID, use the following:

SELECT  *
FROM    employees e
WHERE   NOT EXISTS
        (
        SELECT  null 
        FROM    eotm_dyn d
        WHERE   d.employeeID = e.id
        )

You can join these tables with a LEFT JOIN keyword and filter out the NULL's, but this will likely be less efficient than using NOT EXISTS.

I was face-off a similar situation, I need to provide to my WS: Username, Password and WSS Password Type.

I was initially using the "Http Basic Auth" (as @ahoge), I tried to use the @Philipp-Dev 's ref. too. I didn't get a success solution.

After a little deep search at google, I found this post:

And there was my problem solution

I hope this can help to anyone else, like helps to me.

If you need more flexibility in selecting the processes use

for KILLPID in `ps ax | grep 'my_pattern' | awk ' { print $1;}'`; do 
  kill -9 $KILLPID;
done

You can use grep -e etc.

I know this posting is old, but I had the same problem, WAMP would not go online (green) while SKYPE was running. I simply closed SKYPE, ran WAMP and then reloaded SKYPE. I have not verified this, but I think SKYPE port corrected to allow for WAMP settings. At least I have not experienced any problems doing it this way

public class Statistics {
    double[] data;

        for(double a : data)
            sum += a;
        return sum/size;
    }

    double getVariance() {
        double mean = getMean();
        double temp = 0;
        for(double a :data)
            temp += (a-mean)*(a-mean);
        return temp/(size-1);
    }

    double getStdDev() {
        return Math.sqrt(getVariance());
    }

          return (data[(data.length / 2) - 1] + data[data.length / 2]) / 2.0;
       return data[data.length / 2];
    }
}

It's available in both npm and bower, which is why I have been using it.

If the POM missing warning is of project's self module, the reason is that you are trying to mistakenly build from a sub-module directory. You need to run the build and install command from root directory of the project.

To continue using the iframe YouTube, you should only have to change ?autoplay=1 to ?autoplay=0.

Another way to accomplish this would be by using the YouTube JavaScript Player API. (https://developers.google.com/youtube/js_api_reference)

Edit: the YouTube JavaScript Player API is no longer supported.

<div id="howToVideo"></div>

<script type="application/javascript">

    var ga = document.createElement('script');
    ga.type = 'text/javascript';
    ga.async = false;
    ga.src = 'http://www.youtube.com/player_api';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(ga, s);

    var done = false;
    var player;

    function onYouTubePlayerAPIReady() {
        player = new YT.Player('howToVideo', {
            height: '390',
            width: '640',
            videoId: 'qUJYqhKZrwA',
        playerVars: {
            controls: 0,
            disablekb: 1
        },
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
    }
    function onPlayerReady(evt) {
        console.log('onPlayerReady', evt);
    }
    function onPlayerStateChange(evt) {
        console.log('onPlayerStateChange', evt);
        if (evt.data == YT.PlayerState.PLAYING && !done) {
            setTimeout(stopVideo, 6000);
            done = true;
        }
    }

    function stopVideo() {
        console.log('stopVideo');
        player.stopVideo();
    }

</script>

Here is a jsfiddle for the example: http://jsfiddle.net/fgkrj/

Note that player controls are disabled in the "playerVars" part of the player. The one sacrifice you make is that users are still able to pause the video by clicking on it. I would suggest writing a simple javascript function that subscribes to a stop event and calls player.playVideo().

I find it more useful to use mousedown-event instead of click-event. The click-event doesn't work if the user clicks on other elements on the page with click-events. In combination with jQuery's one() method it looks like this:

$("ul.opMenu li").click(function(event){

   //event.stopPropagation(); not required any more
   $('#MainOptSubMenu').show();

   // add one mousedown event to html
   $('html').one('mousedown', function(){
       $('#MainOptSubMenu').hide();
   });
});

// mousedown must not be triggered inside menu
$("ul.opMenu li").bind('mousedown', function(evt){
    evt.stopPropagation();
});

import org.springframework.core.io.ClassPathResource;

...

File folder = new ClassPathResource("sql").getFile();
File[] listOfFiles = folder.listFiles();

It is worth noting that this will limit your deployment options, ClassPathResource.getFile() only works if the container has exploded (unzipped) your war file.

Adding to the spans

vertical-align:baseline;

Didn't work for me but

vertical-align:baseline;
vertical-align:-webkit-baseline-middle;

did work (tested on Chrome)

If possible I would suggest creating the Path directly from the path elements:

Path path = Paths.get("C:", "dir1", "dir2", "dir3");
// if needed
String textPath = path.toString(); // "C:\\dir1\\dir2\\dir3"

// loading bytes from a file is very easy in C#. The built in System.IO.File.ReadAll* methods take care of making sure every byte is read properly.
// note that for Linux, you will not need the c: part
// just swap out the example folder here with your actual full file path
string pdfFilePath = "c:/pdfdocuments/myfile.pdf";
byte[] bytes = System.IO.File.ReadAllBytes(pdfFilePath);

// munge bytes with whatever pdf software you want, i.e. http://sourceforge.net/projects/itextsharp/
// bytes = MungePdfBytes(bytes); // MungePdfBytes is your custom method to change the PDF data
// ...
// make sure to cleanup after yourself

// and save back - System.IO.File.WriteAll* makes sure all bytes are written properly - this will overwrite the file, if you don't want that, change the path here to something else
System.IO.File.WriteAllBytes(pdfFilePath, bytes);

Let we have the following 2 tables(salary and employee)

Now i want those records from employee table which are not in salary. We can do this in 3 ways:

1. Using inner Join

select * from employee
where id not in(select e.id from employee e inner join salary s on e.id=s.id)

2. Using Left outer join

select * from employee e 
left outer join salary s on e.id=s.id  where s.id is null

3. Using Full Join

select * from employee e
full outer join salary s on e.id=s.id where e.id not in(select id from salary)

Instantiate the class Date and call upon its getFullYear method to get the current year in yyyy format. Something like this:

let currentYear = new Date().getFullYear;

The currentYear variable will hold the value you are looking out for.

It's a chunk of memory allocated from the operating system by the memory manager in use by a process. Calls to malloc() et alia then take memory from this heap instead of having to deal with the operating system directly.

If you have setup.py in your project and you use find_packages() within it, it is necessary to have an __init__.py file in every directory for packages to be automatically found.

Packages are only recognized if they include an __init__.py file

UPD: If you want to use implicit namespace packages without __init__.py you just have to use find_namespace_packages() instead

Using the following 1 line command for changing many files name in linux using phrase specificity:

find -type f -name '*.jpg' | rename 's/holiday/honeymoon/'

For all files with the extension ".jpg", if they contain the string "holiday", replace it with "honeymoon". For instance, this command would rename the file "ourholiday001.jpg" to "ourhoneymoon001.jpg".

This example also illustrates how to use the find command to send a list of files (-type f) with the extension .jpg (-name '*.jpg') to rename via a pipe (|). rename then reads its file list from standard input.

When you use the input function it automatically turns it into a string. You need to go:

vote = int(input('Enter the name of the player you wish to vote for'))

which turns the input into a int type value

To answer the actual question, now that nearly a dozen approaches to working around a solution have been posted: x.transpose reverses the shape of x. One of the interesting side-effects is that if x.ndim == 1, the transpose does nothing.

This is especially confusing for people coming from MATLAB, where all arrays implicitly have at least two dimensions. The correct way to transpose a 1D numpy array is not x.transpose() or x.T, but rather

x[:, None]

or

x.reshape(-1, 1)

From here, you can multiply by a matrix of ones, or use any of the other suggested approaches, as long as you respect the (subtle) differences between MATLAB and numpy.

Names surrounded by double underscores are "special" to Python. They're listed in the Python Language Reference, section 3, "Data model".

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

        <Grid>

If you don't want to modify current codes and just for debug usage.

Add this macro:

#define printf(args...) fprintf(stderr, ##args)
//under GCC
#define printf(args...) fprintf(stderr, __VA_ARGS__)
//under MSVC

Change stderr to stdout if you want to roll back.

It's helpful for debug, but it's not a good practice.

The advantages of using case classes over Enumerations are:

• When using sealed case classes, the Scala compiler can tell if the match is fully specified e.g. when all possible matches are espoused in the matching declaration. With enumerations, the Scala compiler cannot tell.
• Case classes naturally supports more fields than a Value based Enumeration which supports a name and ID.

The advantages of using Enumerations instead of case classes are:

• Enumerations will generally be a bit less code to write.
• Enumerations are a bit easier to understand for someone new to Scala since they are prevalent in other languages

So in general, if you just need a list of simple constants by name, use enumerations. Otherwise, if you need something a bit more complex or want the extra safety of the compiler telling you if you have all matches specified, use case classes.

nan means "not a number", a float value that you get if you perform a calculation whose result can't be expressed as a number. Any calculations you perform with NaN will also result in NaN.

inf means infinity.

For example:

>>> 2*float("inf")
inf
>>> -2*float("inf")
-inf
>>> float("inf")-float("inf")
nan

Here is the code to check if AZ module is installed or not:

$checkModule = "AZ"

$Installedmodules = Get-InstalledModule

if ($Installedmodules.name -contains $checkModule)
{

    "$checkModule is installed "

}

else {

    "$checkModule is not installed"

}

A variation using just standard color code:

android:textColor="#ff0000"

Non-validating URI-reference Parser

For reference purposes, here's the IETF Spec: (TXT | HTML). In particular, Appendix B. Parsing a URI Reference with a Regular Expression demonstrates how to parse a valid regex. This is described as,

for an example of a non-validating URI-reference parser that will take any given string and extract the URI components.

Here's the regex they provide:

 ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?

As someone else said, it's probably best to leave this to a lib/framework you're already using.

Workaround:

Window -> Preferences -> Java -> Installed JREs, select a different JRE

So try this one instead:

Problem solved!

JEP 354: Switch Expressions (Preview) in JDK-13 and JEP 361: Switch Expressions (Standard) in JDK-14 will extend the switch statement so it can be used as an expression.

Now you can:

• directly assign variable from switch expression,
• use new form of switch label (case L ->):

  The code to the right of a "case L ->" switch label is restricted to be an expression, a block, or (for convenience) a throw statement.

• use multiple constants per case, separated by commas,
• and also there are no more value breaks:

  To yield a value from a switch expression, the break with value statement is dropped in favor of a yield statement.

Switch expression example:

public class SwitchExpression {

  public static void main(String[] args) {
      int month = 9;
      int year = 2018;
      int numDays = switch (month) {
        case 1, 3, 5, 7, 8, 10, 12 -> 31;
        case 4, 6, 9, 11 -> 30;
        case 2 -> {
          if (java.time.Year.of(year).isLeap()) {
            System.out.println("Wow! It's leap year!");
            yield 29;
          } else {
            yield 28;
          }
        }
        default -> {
          System.out.println("Invalid month.");
          yield 0;
        }
      };
      System.out.println("Number of Days = " + numDays);
  }
}

As second says, most of the "design" decisions made for TeX documents are backed up by well researched usability studies, so changing them should be undertaken with care. It is, however, relatively common to replace Computer Modern with Times (also a serif face).

Try \usepackage{times}.

I use EasyGit (a.k.a. "eg") as a super lightweight wrapper on top of (or along side of) Git. EasyGit has an "info" subcommand that gives you all kinds of super useful information, including the current branches remote tracking branch. Here's an example (where the current branch name is "foo"):

pknotz@s883422: (foo) ~/workspace/bd
$ eg info
Total commits:      175
Local repository: .git
Named remote repositories: (name -> location)
  origin -> git://sahp7577/home/pknotz/bd.git
Current branch: foo
  Cryptographic checksum (sha1sum): bd248d1de7d759eb48e8b5ff3bfb3bb0eca4c5bf
  Default pull/push repository: origin
  Default pull/push options:
    branch.foo.remote = origin
    branch.foo.merge = refs/heads/aal_devel_1
  Number of contributors:        3
  Number of files:       28
  Number of directories:       20
  Biggest file size, in bytes: 32473 (pygooglechart-0.2.0/COPYING)
  Commits:       62

I figured out how to do this. I was building an application very similar to the example/tutorial you discussed in your original question.

Here's a snippet of the code that worked for me:

        int pageSize = 4;
        int pageNumber = (page ?? 1);
        //Used the following two formulas so that it doesn't round down on the returned integer
        decimal totalPages = ((decimal)(viewModel.Teachers.Count() /(decimal) pageSize));     
        ViewBag.TotalPages = Math.Ceiling(totalPages);  
        //These next two functions could maybe be reduced to one function....would require some testing and building
        viewModel.Teachers = viewModel.Teachers.ToPagedList(pageNumber, pageSize);
        ViewBag.OnePageofTeachers = viewModel.Teachers;
        ViewBag.PageNumber = pageNumber;

        return View(viewModel);

I added

using.PagedList;

to my controller as the tutorial states.

Now in my view my using statements etc at the top, NOTE i didnt change my using model statement.

@model CSHM.ViewModels.TeacherIndexData
@using PagedList;
@using PagedList.Mvc;
<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />

and then at the bottom to build my paged list I used the following and it seems to work. I haven't yet built in the functionality for current sort, showing related data, filters, etc but i dont think it will be that difficult.

Page @ViewBag.PageNumber of @ViewBag.TotalPages

@Html.PagedListPager((IPagedList)ViewBag.OnePageofTeachers, page => Url.Action("Index", new { page }))

Hope that works for you. Let me know if it works!!

AJAX file uploads are now possible by passing a FormData object to the data property of the $.ajax request.

As the OP specifically asked for a jQuery implementation, here you go:

<form id="upload" enctype="multipart/form-data" action="@Url.Action("JsonSave", "Survey")" method="POST">
    <input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
    <button>Upload!</button>
</form>

$('#upload').submit(function(e) {
    e.preventDefault(); // stop the standard form submission

    $.ajax({
        url: this.action,
        type: this.method,
        data: new FormData(this),
        cache: false,
        contentType: false,
        processData: false,
        success: function (data) {
            console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
        },
        error: function(xhr, error, status) {
            console.log(error, status);
        }
    });
});

public JsonResult Survey()
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        var file = Request.Files[i];
        // save file as required here...
    }
    return Json(new { UploadedFileCount = Request.Files.Count });
}

More information on FormData at MDN

On mac I used

sed -i '' -e 's/text-on-line-to-be-changed.*/text-to-replace-the=whole-line/' file-name

That meta tag basically specifies which character set a website is written with.

Here is a definition of UTF-8:

UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

Assuming you're on Windows (if so you should tag your question as such!), on this MSDN page you can find the source for a simple, useful HRTimer C++ class that wraps the needed system calls to do something very close to what you require (it would be easy to add a GetTicks() method to it, in particular, to do exactly what you require).

On non-Windows platforms, there's no QueryPerformanceCounter function, so the solution won't be directly portable. However, if you do wrap it in a class such as the above-mentioned HRTimer, it will be easier to change the class's implementation to use what the current platform is indeed able to offer (maybe via Boost or whatever!).

Here is a simple and elegant way of getting filtered files

var allowedFileExtensions = ".csv,.txt";


var files = Directory.EnumerateFiles(@"C:\MyFolder", "*.*", SearchOption.TopDirectoryOnly)
                .Where(s => allowedFileExtensions.IndexOf(Path.GetExtension(s)) > -1).ToArray(); 

To avoid potentially unexpected results when using GROUP BY without an aggregate function, as is used in the accepted answer, because MySQL is free to retrieve ANY value within the data set being grouped when not using an aggregate function [sic] and issues with ONLY_FULL_GROUP_BY. Please consider using an exclusion join.

Exclusion Join - Unambiguous Entities

Assuming the firstname and lastname are uniquely indexed (unambiguous), an alternative to GROUP BY is to sort using a LEFT JOIN to filter the result set, otherwise known as an exclusion JOIN.

See Demonstration

Ascending order (A-Z)

To retrieve the distinct firstname ordered by lastname from A-Z

Query

SELECT t1.*
FROM table_name AS t1
LEFT JOIN table_name AS t2
ON t1.firstname = t2.firstname
AND t1.lastname > t2.lastname
WHERE t2.id IS NULL;

Result

| id | firstname | lastname |
|----|-----------|----------|
|  2 |      Bugs |    Bunny |
|  1 |      John |      Doe |

Descending order (Z-A)

To retrieve the distinct firstname ordered by lastname from Z-A

Query

SELECT t1.*
FROM table_name AS t1
LEFT JOIN table_name AS t2
ON t1.firstname = t2.firstname
AND t1.lastname < t2.lastname
WHERE t2.id IS NULL;

Result

| id | firstname | lastname |
|----|-----------|----------|
|  2 |      Bugs |    Bunny |
|  3 |      John |  Johnson |

You can then order the resulting data as desired.

Exclusion Join - Ambiguous Entities

If the first and last name combination are not unique (ambiguous) and you have multiple rows of the same values, you can filter the result set by including an OR condition on the JOIN criteria to also filter by id.

See Demonstration

table_name data

(1, 'John', 'Doe'),
(2, 'Bugs', 'Bunny'),
(3, 'John', 'Johnson'),
(4, 'John', 'Doe'),
(5, 'John', 'Johnson')

Query

SELECT t1.*
FROM table_name AS t1
LEFT JOIN table_name AS t2
ON t1.firstname = t2.firstname
AND (t1.lastname > t2.lastname
OR (t1.firstname = t1.firstname AND t1.lastname = t2.lastname AND t1.id > t2.id))
WHERE t2.id IS NULL;

Result

| id | firstname | lastname |
|----|-----------|----------|
|  1 |      John |      Doe |
|  2 |      Bugs |    Bunny |

Ordered Subquery

EDIT

My original answer using an ordered subquery, was written prior to MySQL 5.7.5, which is no longer applicable, due to the changes with ONLY_FULL_GROUP_BY. Please use the exclusion join examples above instead.

It is also important to note; when ONLY_FULL_GROUP_BY is disabled (original behavior prior to MySQL 5.7.5), the use of GROUP BY without an aggregate function may yield unexpected results, because MySQL is free to choose ANY value within the data set being grouped [sic].

Meaning an ID or lastname value may be retrieved that is not associated with the retrieved firstname row.

WARNING

With MySQL GROUP BY may not yield the expected results when used with ORDER BY

See Test Case Example

The best method of implementation, to ensure expected results, is to filter the result set scope using an ordered subquery.

table_name data

(1, 'John', 'Doe'),
(2, 'Bugs', 'Bunny'),
(3, 'John', 'Johnson')

Query

SELECT * FROM (
    SELECT * FROM table_name ORDER BY ID DESC
) AS t1
GROUP BY FirstName

Result

| ID | first |    last |
|----|-------|---------|
|  2 |  Bugs |   Bunny |
|  3 |  John | Johnson |

Comparison

To demonstrate the unexpected results when using GROUP BY in combination with ORDER BY

Query

SELECT * FROM table_name GROUP BY FirstName ORDER BY ID DESC

Result

| ID | first |  last |
|----|-------|-------|
|  2 |  Bugs | Bunny |
|  1 |  John |   Doe |

I have used winston logger earlier.

Nowadays I am using below simpler code from experience:

1. Set the environment variable from cmd/ command line (on Windows):

   cmd
   setx LOG_LEVEL info
   

Or, you could have a variable in your code if you like, but above is better.

2. Restart cmd/ command line, or, IDE/ editor like Netbeans

3. Have below like code:

   console.debug = console.log;   // define debug function
   console.silly = console.log;   // define silly function
   
   switch (process.env.LOG_LEVEL) {
       case 'debug':
       case 'silly':
           // print everything
           break;
   
       case 'dir':
       case 'log':
           console.debug = function () {};
           console.silly = function () {};
           break;
   
       case 'info':
           console.debug = function () {};
           console.silly = function () {};
           console.dir = function () {};
           console.log = function () {};
           break;
   
       case 'trace':   // similar to error, both may print stack trace/ frames
       case 'warn':    // since warn() function is an alias for error()
       case 'error':
           console.debug = function () {};
           console.silly = function () {};
           console.dir = function () {};
           console.log = function () {};
           console.info = function () {};
           break;
   }
   

4. Now use all console.* as below:

   console.error(' this is a error message '); // will print
   console.warn(' this is a warn message '); // will print
   console.trace(' this is a trace message '); // will print
   console.info(' this is a info message '); // will print, LOG_LEVEL is set to this
   
   console.log(' this is a log message '); // will NOT print
   console.dir(' this is a dir message '); // will NOT print
   console.silly(' this is a silly message '); // will NOT print
   console.debug(' this is a debug message '); // will NOT print
   

Now, based on your LOG_LEVEL settings made in the point 1 (like, setx LOG_LEVEL log and restart command line), some of the above will print, others won't print

Hope that helped.

Using PAM is execellent.

For checking type conversions in version 3, you can go to their github and check into the different liquibase types and check the method toDatabaseDataType. For example, for Boolean, you can check here:

https://github.com/liquibase/liquibase/blob/master/liquibase-core/src/main/java/liquibase/datatype/core/BooleanType.java

For version 2.0.x, the conversion seems to be into database specific classes. For example, for Mysql:

https://github.com/liquibase/liquibase/blob/2_0_x/liquibase-core/src/main/java/liquibase/database/typeconversion/core/MySQLTypeConverter.java

Simply subtract them:

SELECT ('2015-01-12'::date - '2015-01-01'::date) AS days;

The result:

 days
------
   11

jquery validation plugin version work fine v1.15.0 but v1.17.0 not work for me.

$(document).find('#add_patient_form').validate({
          ignore: [],
          rules:{
            'email[]':
            {
              required:true,
            },               
          },
          messages:{
            'email[]':
            {
              'required':'Required'
            },            
          },    
        });

what about using the official API?

According to the API doc:

DESTROY: Removes the datepicker functionality completely. This will return the element back to its pre-init state.

Use:

$("#txtSearch").datepicker("destroy");

to restore the input to its normal behaviour and

$("#txtSearch").datepicker(/*options*/);

again to show the datapicker again.

function searchForId($id, $array) {
   foreach ($array as $key => $val) {
       if ($val['uid'] === $id) {
           return $key;
       }
   }
   return null;
}

This will work. You should call it like this:

$id = searchForId('100', $userdb);

It is important to know that if you are using === operator compared types have to be exactly same, in this example you have to search string or just use == instead ===.

Based on angoru answer. In later versions of PHP (>= 5.5.0) you can use one-liner.

$key = array_search('100', array_column($userdb, 'uid'));

Here is documentation: http://php.net/manual/en/function.array-column.php.

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

T = map(lambda i: L[i], Idx)

I had the same issue with Base64 not being defined. I went to an online encoder and then saved the output into a variable. This probably is not ideal for many images, but for my needs it was sufficient.

function makePDF(){
    var doc = new jsPDF();
    var image = "data:image/png;base64,iVBORw0KGgoAA..";
    doc.addImage(image, 'JPEG', 15, 40, 180, 160);
    doc.save('title');
}

I already had this problem before.

Choose "Run" then "Edit Configurations". In the "General" tab, check the "Deployment Target Options" section.

In my case, the target was already set to "USB Device" and the checkbox "Use same device for future launches" was checked.

I had to change the target to "Show Device Chooser Dialog" and I unchecked the check box. Then my device appeared in the list.

If your device still doesn't appear, then you have to enable USB-Debugging in the smartphone settings again.

Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.

It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.

Update will give you better performance with a queryset of more than one object, as it will make one database call per queryset.

However save is useful, as it is easy to override the save method in your model and add extra logic there. In my own application for example, I update a dates when other fields are changed.

Class myModel(models.Model): 
    name = models.CharField()
    date_created = models.DateField()

    def save(self):
        if not self.pk :
           ### we have a newly created object, as the db id is not set
           self.date_created = datetime.datetime.now()
        super(myModel , self).save()

Take a look at this , we can simply do this with outline-offset property

Output image look like

.black_box {_x000D_
    width:500px;_x000D_
    height:200px;_x000D_
    background:#000;_x000D_
    float:left;_x000D_
    border:2px solid #000;_x000D_
    outline: 1px dashed #fff;_x000D_
    outline-offset: -10px;_x000D_
}

<div class="black_box"></div>

This answer is specific for WordPress:

$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

$media_dir = $base_dir . 'yourfolder/images/';
$media_url = $hase_url . 'yourfolder/images/';

$image_paths = glob( $media_dir . '*.jpg' );
$image_names = array();
$image_urls = array();

foreach ( $image_paths as $image ) {
    $image_names[] = str_replace( $media_dir, '', $image );
    $image_urls[] = str_replace( $media_dir, $media_url, $image );
}

// --- You now have:

// $image_paths ... list of absolute file paths 
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg

// $image_urls ... list of absolute file URLs 
// e.g. http://example.com/wp-content/uploads/yourfolder/images/sample.jpg

// $image_names ... list of filenames only
// e.g. sample.jpg

Here are some other settings that will give you images from other places than the child theme. Just replace the first 2 lines in above code with the version you need:

From Uploads directory:

// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
$upload_path = wp_upload_dir();
$base_dir = trailingslashit( $upload_path['basedir'] );
$base_url = trailingslashit( $upload_path['baseurl'] );

From Parent-Theme

// e.g. /path/to/wordpress/wp-content/themes/parent-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_template_directory() );
$base_url = trailingslashit( get_template_directory_uri() );

From Child-Theme

// e.g. /path/to/wordpress/wp-content/themes/child-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

Matt Trout's overview lists five choices, from perl -de 0 onwards, and he recommends Reply, if extensibility via plugins is important, or tinyrepl from Eval::WithLexicals, for a minimal, pure-perl solution that includes readline support and lexical persistence.

You could try

 try{
        if(webDriver.switchTo().alert() != null){
           Alert alert = webDriver.switchTo().alert();
           alert.getText();
           //etc.
        }
    }catch(Exception e){}

If that doesn't work, you could try looping through all the window handles and see if the alert exists. I'm not sure if the alert opens as a new window using selenium.

for(String s: webDriver.getWindowHandles()){
 //see if alert exists here.
}

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

Update:

Bootstrap 3 has been released since this question was originally answered in January, so if you are a BS3 user, please refer to the BS3 documentation. For those still on BS2, the original answer still applies. If you are interested in switching from 2 to 3, see the migration guide.

Original answer:

From the bootstrap 2 docs:

Make any row "fluid" by changing .row to .row-fluid. The column classes stay the exact same, making it easy to flip between fixed and fluid grids.

Code

<div class="row-fluid">
  <div class="span4">...</div>
  <div class="span8">...</div>
</div>

This, in conjunction with setting the width of your container to a fluid value, should allow you to get your desired layout.

When initializing an array, C allows you to fill it with values. So

char s[100] = "abcd";

is basically the same as

int s[3] = { 1, 2, 3 };

but it doesn't allow you to do the assignment since s is an array and not a free pointer. The meaning of

s = "abcd" 

is to assign the pointer value of abcd to s but you can't change s since then nothing will be pointing to the array.
This can and does work if s is a char* - a pointer that can point to anything.

If you want to copy the string simple use strcpy.

In C++ new/delete call the Constructor/Destructor accordingly.

malloc/free simply allocate memory from the heap. new/delete allocate memory as well.

Here's a little app to get you started...

import difflib as dl

a = file('file').read()
b = file('file1').read()

sim = dl.get_close_matches

s = 0
wa = a.split()
wb = b.split()

for i in wa:
    if sim(i, wb):
        s += 1

n = float(s) / float(len(wa))
print '%d%% similarity' % int(n * 100)

use

pattern.compile("\"");
String s= p.toString()+"yourcontent"+p.toString();

will give result as yourcontent as is

Sam's answer gives the reason that default arguments are preferable for constructors rather than overloading. I just want to add that C++-0x will allow delegation from one constructor to another, thereby removing the need for defaults.

Use pass for no-op:

if x == 0:
  pass
else:
  print "x not equal 0"

And here's another example:

def f():
  pass

Or:

class c:
  pass

Using a custom spinner layout like this:

<?xml version="1.0" encoding="utf-8"?>
<Spinner xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/spinnerTarget"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:textSize="14dp"         
          android:textColor="#000000"/>

In the activity:

    // populate the list
    ArrayList<String> dataList = new ArrayList<String>();
    for (int i = 0; i < 4; i++) {
        dataList.add("Item");
    }

    // set custom layout spinner_layout.xml and adapter
    Spinner spinnerObject = (Spinner) findViewById(R.id.spinnerObject);
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, R.drawable.spinner_layout, dataList);
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinnerObject.setAdapter(dataAdapter);
    spinnerObject.setOnTouchListener(new View.OnTouchListener() { 

        public boolean onTouch(View v, MotionEvent event) {
            // to set value of first selection, because setOnItemSelectedListener will not dispatch if the user selects first element
            TextView spinnerTarget = (TextView)v.findViewById(R.id.spinnerTarget);
            spinnerTarget.setText(spinnerObject.getSelectedItem().toString());

            return false;
        }

    });
    spinnerObject.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                private boolean selectionControl = true;

                public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
                    // just the first time
                    if(selectionControl){

                        // find TextView in layout 
                        TextView spinnerTarget = (TextView)parent.findViewById(R.id.spinnerTarget);
                        // set spinner text empty
                        spinnerTarget.setText("");
                        selectionControl = false;
                    }
                    else{
                        // select object
                    }
                }

                public void onNothingSelected(AdapterView<?> parent) {

You can center absolute items by providing the left property with the width of the device divided by two and subtracting out half of the element you'd like to center's width.

For example, your style might look something like this.

bottom: {
    position: 'absolute',
    left: (Dimensions.get('window').width / 2) - 25,
    top: height*0.93,
}

The quick and simple answer is No.

Javascript is quite a high level language and does not have access to this sort of information.

I am assuming you want to do something programatically.

You might consider, using getenv to pull the value out of the ORACLE_HOME environmental variable. Assuming you are talking C or C++ or Pro*C.

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

Adding a second drive is probably easiest. That would only take a few minutes, and it wouldn't require any configuration, really.

Alternatively, you could create the second, bigger drive, then run a disk imaging utility to copy all data on disk1 to disk2. That certainly shouldn't take a few hours, but it would take longer than just living with two drives.

I use the following method, it returns a string from stdin (I use it for json parsing). It works with pipe and prompt on Windows (not tested on Linux yet). When prompting, two line breaks indicate end of input.

def get_from_stdin():

  lb = 0
  stdin = ''

  for line in sys.stdin:
    if line == "\n":
        lb += 1
        if lb == 2:
            break
    else:
        lb = 0
        stdin += line

  return stdin

If you want to add the elements in a list (list2) to the end of other list (list), then you can use the list extend method

list = [1, 2, 3]
list2 = [4, 5, 6]
list.extend(list2)
print list
[1, 2, 3, 4, 5, 6]

Or if you want to concatenate two list then you can use + sign

list3 = list + list2
print list3
[1, 2, 3, 4, 5, 6]

TL;DR:

They use a stack architecture with cached graphs for everything above the MySQL bottom of their stack.

Long Answer:

I did some research on this myself because I was curious how they handle their huge amount of data and search it in a quick way. I've seen people complaining about custom made social network scripts becoming slow when the user base grows. After I did some benchmarking myself with just 10k users and 2.5 million friend connections - not even trying to bother about group permissions and likes and wall posts - it quickly turned out that this approach is flawed. So I've spent some time searching the web on how to do it better and came across this official Facebook article:

• TAO: Facebook’s Distributed Data Store for the Social Graph
• TAO: The power of the graph.

I really recommend you to watch the presentation of the first link above before continue reading. It's probably the best explanation of how FB works behind the scenes you can find.

The video and article tells you a few things:

• They're using MySQL at the very bottom of their stack
• Above the SQL DB there is the TAO layer which contains at least two levels of caching and is using graphs to describe the connections.
• I could not find anything on what software / DB they actually use for their cached graphs

Let's take a look at this, friend connections are top left:

Well, this is a graph. :) It doesn't tell you how to build it in SQL, there are several ways to do it but this site has a good amount of different approaches. Attention: Consider that a relational DB is what it is: It's thought to store normalised data, not a graph structure. So it won't perform as good as a specialised graph database.

Also consider that you have to do more complex queries than just friends of friends, for example when you want to filter all locations around a given coordinate that you and your friends of friends like. A graph is the perfect solution here.

I can't tell you how to build it so that it will perform well but it clearly requires some trial and error and benchmarking.

Here is my disappointing test for just findings friends of friends:

DB Schema:

CREATE TABLE IF NOT EXISTS `friends` (
`id` int(11) NOT NULL,
  `user_id` int(11) NOT NULL,
  `friend_id` int(11) NOT NULL
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

Friends of Friends Query:

(
        select friend_id
        from friends
        where user_id = 1
    ) union (
        select distinct ff.friend_id
        from
            friends f
            join friends ff on ff.user_id = f.friend_id
        where f.user_id = 1
    )

I really recommend you to create you some sample data with at least 10k user records and each of them having at least 250 friend connections and then run this query. On my machine (i7 4770k, SSD, 16gb RAM) the result was ~0.18 seconds for that query. Maybe it can be optimized, I'm not a DB genius (suggestions are welcome). However, if this scales linear you're already at 1.8 seconds for just 100k users, 18 seconds for 1 million users.

This might still sound OKish for ~100k users but consider that you just fetched friends of friends and didn't do any more complex query like "display me only posts from friends of friends + do the permission check if I'm allowed or NOT allowed to see some of them + do a sub query to check if I liked any of them". You want to let the DB do the check on if you liked a post already or not or you'll have to do in code. Also consider that this is not the only query you run and that your have more than active user at the same time on a more or less popular site.

I think my answer answers the question how Facebook designed their friends relationship very well but I'm sorry that I can't tell you how to implement it in a way it will work fast. Implementing a social network is easy but making sure it performs well is clearly not - IMHO.

I've started experimenting with OrientDB to do the graph-queries and mapping my edges to the underlying SQL DB. If I ever get it done I'll write an article about it.

TV Sony Bravia KLV-32T550A Below mention config works greatly You should add the following into the /boot/config.txt to force the output to HDMI and set the

resolution 82   1920x1080   60Hz    1080p

hdmi_ignore_edid=0xa5000080
hdmi_force_hotplug=1
hdmi_boost=7
hdmi_group=2
hdmi_mode=82
hdmi_drive=1

The syntax problem is shadowing method and variable names. In the current version sort_word_list() is a method, and sorted_word_list is a variable, whereas num_words is both. Also, list.sort() modifies the list and replaces it with a sorted version; the sorted(list) function actually returns a new list.

But I suspect this indicates a design problem. What's the point of calls like

test.parser()
test.sort_word_list()
test.num_words()

which don't do anything? You should probably just have the methods figure out whether the appropriate counting and/or sorting has been done, and, if appropriate, do the count or sort and otherwise just return something.

E.G.,

def sort_word_list(self):
   if self.sorted_word_list is not None:
      self.sorted_word_list = sorted(self.word_list)
   return self.sorted_word_list

(Alternately, you could use properties.)

The last thing on the Laravel Eloquent doc page is:

protected $appends = array('is_admin');

That can be used automatically to add new accessors to the model without any additional work like modifying methods like ::toArray().

Just create getFooBarAttribute(...) accessor and add the foo_bar to $appends array.

Use this one :

 onSelect: function(dateText) {
                 $("input#DateTo").datepicker('option', 'minDate', dateText);
            }

You should not add C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng to your PATH. There is only a javascript file which you cannot use in terminal.

You need ng.cmd which is probably located at %AppData%\Roaming\npm. Make sure this path is included in your PATH variable.

I think you need the btn class.
It would be like this:

<a class="btn disabled" href="#">Disabled link</a>

Try:

With DependencedIncidents AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
),
lalala AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
)

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

You can just do git merge <commit-number> or git cherry-pick <commit> <commit> ...

As suggested by Ryan Stewart you may also create a branch from the current HEAD:

git branch brand-name

Or just a tag:

git tag tag-name

I'll try and break it down (example from documention)

/* 
 *   The cellForRowAtIndexPath takes for argument the tableView (so if the same object
 *   is delegate for several tableViews it can identify which one is asking for a cell),
 *   and an indexPath which determines which row and section the cell is returned for. 
 */ 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    /*
     *   This is an important bit, it asks the table view if it has any available cells
     *   already created which it is not using (if they are offScreen), so that it can
     *   reuse them (saving the time of alloc/init/load from xib a new cell ).
     *   The identifier is there to differentiate between different types of cells
     *   (you can display different types of cells in the same table view)
     */

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];

    /*
     *   If the cell is nil it means no cell was available for reuse and that we should
     *   create a new one.
     */
    if (cell == nil) {

        /* 
         *   Actually create a new cell (with an identifier so that it can be dequeued). 
         */

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MyIdentifier"] autorelease];

        cell.selectionStyle = UITableViewCellSelectionStyleNone;

    }

    /*
     *   Now that we have a cell we can configure it to display the data corresponding to
     *   this row/section
     */

    NSDictionary *item = (NSDictionary *)[self.content objectAtIndex:indexPath.row];
    cell.textLabel.text = [item objectForKey:@"mainTitleKey"];
    cell.detailTextLabel.text = [item objectForKey:@"secondaryTitleKey"];
    NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:@"imageKey"] ofType:@"png"];
    UIImage *theImage = [UIImage imageWithContentsOfFile:path];
    cell.imageView.image = theImage;

    /* Now that the cell is configured we return it to the table view so that it can display it */

    return cell;

}

This is a DataSource method so it will be called on whichever object has declared itself as the DataSource of the UITableView. It is called when the table view actually needs to display the cell onscreen, based on the number of rows and sections (which you specify in other DataSource methods).

There are several ways rsync compares files -- the authoritative source is the rsync algorithm description: https://www.andrew.cmu.edu/course/15-749/READINGS/required/cas/tridgell96.pdf. The wikipedia article on rsync is also very good.

For local files, rsync compares metadata and if it looks like it doesn't need to copy the file because size and timestamp match between source and destination it doesn't look further. If they don't match, it cp's the file. However, what if the metadata do match but files aren't actually the same? Then rsync probably didn't do what you intended.

Files that are the same size may still have changed. One simple example is a text file where you correct a typo -- like changing "teh" to "the". The file size is the same, but the corrected file will have a newer timestamp. --size-only says "don't look at the time; if size matches assume files match", which would be the wrong choice in this case.

On the other hand, suppose you accidentally did a big cp -r A B yesterday, but you forgot to preserve the time stamps, and now you want to do the operation in reverse rsync B A. All those files you cp'ed have yesterday's time stamp, even though they weren't really modified yesterday, and rsync will by default end up copying all those files, and updating the timestamp to yesterday too. --size-only may be your friend in this case (modulo the example above).

--ignore-times says to compare the files regardless of whether the files have the same modify time. Consider the typo example above, but then not only did you correct the typo but you used touch to make the corrected file have the same modify time as the original file -- let's just say you're sneaky that way. Well --ignore-times will do a diff of the files even though the size and time match.

SOLVED - not rendering border radius correctly in IE 10 and 11

For those not getting the -ms-border-radius: or the border-radius: to work in IE 10,11 And it renders all square then follow these steps:

1. Click on the gear wheel at the top right of the IE browser
2. Click on Compatibility view settings
3. Now uncheck the 2 boxes that are checked by default.

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

That is interesting subject. You can play around with two lifecycle hooks to figure out how it works: ngOnChanges and ngOnInit.

Basically when you set default value to Input that's mean it will be used only in case there will be no value coming on that component. And the interesting part it will be changed before component will be initialized.

Let's say we have such components with two lifecycle hooks and one property coming from input.

@Component({
  selector: 'cmp',
})
export class Login implements OnChanges, OnInit {
  @Input() property: string = 'default';

  ngOnChanges(changes) {
    console.log('Changed', changes.property.currentValue, changes.property.previousValue);
  }

  ngOnInit() {
    console.log('Init', this.property);
  }

}

Situation 1

Component included in html without defined property value

As result we will see in console: Init default

That's mean onChange was not triggered. Init was triggered and property value is default as expected.

Situation 2

Component included in html with setted property <cmp [property]="'new value'"></cmp>

As result we will see in console:

Changed new value Object {}

Init new value

And this one is interesting. Firstly was triggered onChange hook, which setted property to new value, and previous value was empty object! And only after that onInit hook was triggered with new value of property.

Use the other encode method in URLEncoder:

URLEncoder.encode(String, String)

The first parameter is the text to encode; the second is the name of the character encoding to use (e.g., UTF-8). For example:

System.out.println(
  URLEncoder.encode(
    "urlParameterString",
    java.nio.charset.StandardCharsets.UTF_8.toString()
  )
);

Probably too late but this is how I resolved this error.

If this solution is not working,

<init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>/* Name of Package where your service class exists */</param-value>
</init-param>

How do I convert ElementTree.Element to a String?

For Python 3:

xml_str = ElementTree.tostring(xml, encoding='unicode')

For Python 2:

xml_str = ElementTree.tostring(xml, encoding='utf-8')

The following is compatible with both Python 2 & 3, but only works for Latin characters:

xml_str = ElementTree.tostring(xml).decode()

Example usage

from xml.etree import ElementTree

xml = ElementTree.Element("Person", Name="John")
xml_str = ElementTree.tostring(xml).decode()
print(xml_str)

Output:

<Person Name="John" />

Explanation

Despite what the name implies, ElementTree.tostring() returns a bytestring by default in Python 2 & 3. This is an issue in Python 3, which uses Unicode for strings.

In Python 2 you could use the str type for both text and binary data. Unfortunately this confluence of two different concepts could lead to brittle code which sometimes worked for either kind of data, sometimes not. [...]

To make the distinction between text and binary data clearer and more pronounced, [Python 3] made text and binary data distinct types that cannot blindly be mixed together.

^{Source: Porting Python 2 Code to Python 3}

If we know what version of Python is being used, we can specify the encoding as unicode or utf-8. Otherwise, if we need compatibility with both Python 2 & 3, we can use decode() to convert into the correct type.

For reference, I've included a comparison of .tostring() results between Python 2 and Python 3.

ElementTree.tostring(xml)
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />

ElementTree.tostring(xml, encoding='unicode')
# Python 3: <Person Name="John" />
# Python 2: LookupError: unknown encoding: unicode

ElementTree.tostring(xml, encoding='utf-8')
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />

ElementTree.tostring(xml).decode()
# Python 3: <Person Name="John" />
# Python 2: <Person Name="John" />

Thanks to Martijn Peters for pointing out that the str datatype changed between Python 2 and 3.

Why not use str()?

In most scenarios, using str() would be the "cannonical" way to convert an object to a string. Unfortunately, using this with Element returns the object's location in memory as a hexstring, rather than a string representation of the object's data.

from xml.etree import ElementTree

xml = ElementTree.Element("Person", Name="John")
print(str(xml))  # <Element 'Person' at 0x00497A80>

You forgot the actual JSON part - data is a dictionary and not yet JSON-encoded. Write it like this for maximum compatibility (Python 2 and 3):

import json
with open('data.json', 'w') as f:
    json.dump(data, f)

On a modern system (i.e. Python 3 and UTF-8 support), you can write a nicer file with

import json
with open('data.json', 'w', encoding='utf-8') as f:
    json.dump(data, f, ensure_ascii=False, indent=4)

Generate 8 characters key

lpad(conv(floor(rand()*pow(36,6)), 10, 36), 8, 0); 

How do I generate a unique, random string for one of my MySql table columns?

The easiest answer: jQuery. Do something like this:

$(document).ready(function(){
   var $form = $('form');
   $form.submit(function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });
});

If you want to add content dynamically and still need it to work, and also with more than one form, you can do this:

   $('form').live('submit', function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });

I am highlighting the solution in both 1.9 and 2.0 since it is useful for some

In 1.9, I think the better solution is to save the file to disk and use it as Typed file like:

RetroFit 1.9

(I don't know about your server-side implementation) have an API interface method similar to this

@POST("/en/Api/Results/UploadFile")
void UploadFile(@Part("file") TypedFile file,
                @Part("folder") String folder,
                Callback<Response> callback);

And use it like

TypedFile file = new TypedFile("multipart/form-data",
                                       new File(path));

For RetroFit 2 Use the following method

RetroFit 2.0 ( This was a workaround for an issue in RetroFit 2 which is fixed now, for the correct method refer jimmy0251's answer)

API Interface:

public interface ApiInterface {

    @Multipart
    @POST("/api/Accounts/editaccount")
    Call<User> editUser(@Header("Authorization") String authorization,
                        @Part("file\"; filename=\"pp.png\" ") RequestBody file,
                        @Part("FirstName") RequestBody fname,
                        @Part("Id") RequestBody id);
}

Use it like:

File file = new File(imageUri.getPath());

RequestBody fbody = RequestBody.create(MediaType.parse("image/*"),
                                       file);

RequestBody name = RequestBody.create(MediaType.parse("text/plain"),
                                      firstNameField.getText()
                                                    .toString());

RequestBody id = RequestBody.create(MediaType.parse("text/plain"),
                                    AZUtils.getUserId(this));

In my case, I tried to open a DOS prompt and go to the MySQL bin\ directory and issue the below command:

mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini" --standalone --console

And it shows me I was missing the "C:\Program Files\MySQL\MySQL Server 5.0\Uploads" folder; I built one and problem solved.

Use forward slashes. See explanation here

In Mac OSX 10.5 or later, Apple recommends to set the $JAVA_HOME variable to /usr/libexec/java_home, just export $JAVA_HOME in file ~/. bash_profile or ~/.profile.

Open the terminal and run the below command.

$ vim .bash_profile

export JAVA_HOME=$(/usr/libexec/java_home)

save and exit from vim editor, then run the source command on .bash_profile

$ source .bash_profile

$ echo $JAVA_HOME

/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

For information, I just had the default root + without password. It didn't work with all previous answers.

• I created a new user with all privileges and a password. It worked.

• -ppassword WITHOUT SPACE.

You could also use GNU screen which just about every Linux/Unix system should have.

If you are on Ubuntu/Debian, its enhanced variant byobu is rather nice too.

Use:

(summary(fit))$coefficients[***num***,4]

where num is a number which denotes the row of the coefficients matrix. It will depend on how many features you have in your model and which one you want to pull out the p-value for. For example, if you have only one variable there will be one p-value for the intercept which will be [1,4] and the next one for your actual variable which will be [2,4]. So your num will be 2.

For anyone coming to this via Google, note that starting from SDK 1.6 Android now has an official native SDK.

You can download the Android NDK (Native Development Kit) from here: https://developer.android.com/ndk/downloads/index.html

Also there is an blog post about the NDK:
http://android-developers.blogspot.com/2009/06/introducing-android-15-ndk-release-1.html

As many people have commented, responsive design very often sets width by %

width:inherit will inherit the CSS width NOT the computed width -- Which means the child container inherits width:100%

But, I think, almost as often responsive design sets max-width too, therefore:

#container {
    width:100%;
    max-width:800px;
}
#contained {
    position:fixed;
    width:inherit;
    max-width:inherit;
}

This worked very satisfyingly to solve my problem of making a sticky menu be restrained to the original parent width whenever it got "stuck"

Both the parent and child will adhere to the width:100% if the viewport is less than the maximum width. Likewise, both will adhere to the max-width:800px when the viewport is wider.

It works with my already responsive theme in a way that I can alter the parent container without having to also alter the fixed child element -- elegant and flexible

ps: I personally think it does not matter one bit that IE6/7 do not use inherit

If you want to delete all duplicates, but one out of each set of duplicates, this is one solution:

DELETE posts
FROM posts
LEFT JOIN (
    SELECT id
    FROM posts
    GROUP BY id
    HAVING COUNT(id) = 1

    UNION

    SELECT id
    FROM posts
    GROUP BY id
    HAVING COUNT(id) != 1
) AS duplicate USING (id)
WHERE duplicate.id IS NULL;

Here is a more general generator function that skips any number of items from the beginning and end of an iterable:

def skip(iterable, at_start=0, at_end=0):
    it = iter(iterable)
    for x in itertools.islice(it, at_start):
        pass
    queue = collections.deque(itertools.islice(it, at_end))
    for x in it:
        queue.append(x)
        yield queue.popleft()

Example usage:

>>> list(skip(range(10), at_start=2, at_end=2))
[2, 3, 4, 5, 6, 7]

TextMarks gives you access to its shared shortcode to send and receive text messages from your app via their API. Messages come from/to 41411 (instead of e.g. a random phone# and unlike e-mail gateways you have the full 160 chars to work with).

You can also tell people to text in your keyword(s) to 41411 to invoke various functionality in your app. There is a JAVA API client along with several other popular languages and very comprehensive documentation and technical support.

The 14 day free trial can be easily extended for developers who are still testing it out and building their apps.

Check it out here: TextMarks API Info

1. As per https://msdn.microsoft.com/en-us/library/ms180065.aspx, "DBCC USEROPTIONS reports an isolation level of 'read committed snapshot' when the database option READ_COMMITTED_SNAPSHOT is set to ON and the transaction isolation level is set to 'read committed'. The actual isolation level is read committed."

2. Also in SQL Server Management Studio, in database properties under Options->Miscellaneous there is "Is Read Committed Snapshot On" option status

At the beginning of your main method, add this line of code :

final long startTime = System.nanoTime();

And then, at the last line of your main method, you can add :

final long duration = System.nanoTime() - startTime;

duration now contains the time in nanoseconds that your program ran. You can for example print this value like this:

System.out.println(duration);

If you want to show duration time in seconds, you must divide the value by 1'000'000'000. Or if you want a Date object: Date myTime = new Date(duration / 1000); You can then access the various methods of Date to print number of minutes, hours, etc.

You can use android:largeHeap="true" to request a larger heap size, but this will not work on any pre Honeycomb devices. On pre 2.3 devices, you can use the VMRuntime class, but this will not work on Gingerbread and above.

The only way to have as large a limit as possible is to do memory intensive tasks via the NDK, as the NDK does not impose memory limits like the SDK.

Alternatively, you could only load the part of the model that is currently in view, and load the rest as you need it, while removing the unused parts from memory. However, this may not be possible, depending on your app.

There's also a DataSetExtension method called "AsEnumerable()" (in System.Data) that takes a DataTable and returns an Enumerable. See the MSDN doc for more details, but it's basically as easy as:

dataTable.AsEnumerable()

The downside is that it's enumerating DataRow, not your custom class. A "Select()" LINQ call could convert the row data, however:

private IEnumerable<TankReading> ConvertToTankReadings(DataTable dataTable)
{
    return dataTable.AsEnumerable().Select(row => new TankReading      
            {      
                TankReadingsID = Convert.ToInt32(row["TRReadingsID"]),      
                TankID = Convert.ToInt32(row["TankID"]),      
                ReadingDateTime = Convert.ToDateTime(row["ReadingDateTime"]),      
                ReadingFeet = Convert.ToInt32(row["ReadingFeet"]),      
                ReadingInches = Convert.ToInt32(row["ReadingInches"]),      
                MaterialNumber = row["MaterialNumber"].ToString(),      
                EnteredBy = row["EnteredBy"].ToString(),      
                ReadingPounds = Convert.ToDecimal(row["ReadingPounds"]),      
                MaterialID = Convert.ToInt32(row["MaterialID"]),      
                Submitted = Convert.ToBoolean(row["Submitted"]),      
            });
}

If you have content with height unknown but you know the height the of container. The following solution works extremely well.

HTML

<div class="center-test">
    <span></span><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. 
    Nesciunt obcaecati maiores nulla praesentium amet explicabo ex iste asperiores 
    nisi porro sequi eaque rerum necessitatibus molestias architecto eum velit 
    recusandae ratione.</p>
</div>

CSS

.center-test { 
   width: 300px; 
   height: 300px; 
   text-align: 
   center; 
   background-color: #333; 
}
.center-test span { 
   height: 300px; 
   display: inline-block; 
   zoom: 1; 
   *display: inline; 
   vertical-align: middle; 
 }
.center-test p { 
   display: inline-block; 
   zoom: 1; 
   *display: inline; 
   vertical-align: middle; 
   color: #fff; 
 }

One gotcha for newby's to display: inline-block; [span] and [p] have no html white space so that the span then doesn't take up any space. Also I've added in the CSS hack for display inline-block for IE. Hope this helps someone!

I've tried the code from above and made my own shadow which is little bit closer to what I am trying to achieve. Maybe it will help others too.

What image do you want to hide? Assuming all images, the following should work:

$("img").hide();

Otherwise, using selectors, you could find all images that are child elements of the containing div, and hide those.

However, i strongly recommend you read the Jquery docs, you could have figured it out yourself: http://docs.jquery.com/Main_Page

Unfortunately, if you're trying to debug something at the very start of a Windows Service operation, "attaching" to the running process won't work. I tried using Debugger.Break() within the OnStart procecdure, but with a 64-bit, Visual Studio 2010 compiled application, the break command just throws an error like this:

System error 1067 has occurred.

At that point, you need to set up an "Image File Execution" option in your registry for your executable. It takes five minutes to set up, and it works very well. Here's a Microsoft article where the details are:

How to: Launch the Debugger Automatically

Besides the basic difference of access specifier, and few mentioned above I would like to add some of the major differences including few of the mentioned above with a code sample with output, which will give a more clear idea of the reference and value

Structs:

• Are value types and do not require heap allocation.
• Memory allocation is different and is stored in stack
• Useful for small data structures
• Affect performance, when we pass value to method, we pass the entire data structure and all is passed to the stack.
• Constructor simply returns the struct value itself (typically in a temporary location on the stack), and this value is then copied as necessary
• The variables each have their own copy of the data, and it is not possible for operations on one to affect the other.
• Do not support user-specified inheritance, and they implicitly inherit from type object

Class:

• Reference Type value
• Stored in Heap
• Store a reference to a dynamically allocated object
• Constructors are invoked with the new operator, but that does not allocate memory on the heap
• Multiple variables may have a reference to the same object
• It is possible for operations on one variable to affect the object referenced by the other variable

Code Sample

    static void Main(string[] args)
    {
        //Struct
        myStruct objStruct = new myStruct();
        objStruct.x = 10;
        Console.WriteLine("Initial value of Struct Object is: " + objStruct.x);
        Console.WriteLine();
        methodStruct(objStruct);
        Console.WriteLine();
        Console.WriteLine("After Method call value of Struct Object is: " + objStruct.x);
        Console.WriteLine();

        //Class
        myClass objClass = new myClass(10);
        Console.WriteLine("Initial value of Class Object is: " + objClass.x);
        Console.WriteLine();
        methodClass(objClass);
        Console.WriteLine();
        Console.WriteLine("After Method call value of Class Object is: " + objClass.x);
        Console.Read();
    }
    static void methodStruct(myStruct newStruct)
    {
        newStruct.x = 20;
        Console.WriteLine("Inside Struct Method");
        Console.WriteLine("Inside Method value of Struct Object is: " + newStruct.x);
    }
    static void methodClass(myClass newClass)
    {
        newClass.x = 20;
        Console.WriteLine("Inside Class Method");
        Console.WriteLine("Inside Method value of Class Object is: " + newClass.x);
    }
    public struct myStruct
    {
        public int x;
        public myStruct(int xCons)
        {
            this.x = xCons;
        }
    }
    public class myClass
    {
        public int x;
        public myClass(int xCons)
        {
            this.x = xCons;
        }
    }

Output

Initial value of Struct Object is: 10

Inside Struct Method Inside Method value of Struct Object is: 20

After Method call value of Struct Object is: 10

Initial value of Class Object is: 10

Inside Class Method Inside Method value of Class Object is: 20

After Method call value of Class Object is: 20

Here you can clearly see the difference between call by value and call by reference.

I Concatenated my formula as normal but at the start I had '= instead of =.

Then I copy and paste as text to where I need it. Then I highlight the section saved as text and press ctrl + H to find and replace.
I replace '= with = and all of my functions are active.

Its a few stages but it avoids VBA.

I hope this helps,

If you want to fetch + merge, run

git pull

if you want simply to fetch :

git fetch

Its best to use it for every method intended as an override, and Java 6+, every method intended as an implementation of an interface.

First, it catches misspellings like "hashcode()" instead of "hashCode()" at compile-time. It can be baffling to debug why the result of your method doesn't seem to match your code when the real cause is that your code is never invoked.

Also, if a superclass changes a method signature, overrides of the older signature can be "orphaned", left behind as confusing dead code. The @Override annotation will help you identify these orphans so that they can be modified to match the new signature.

Please note that inserted, deleted means the same thing as inserted CROSS JOIN deleted and gives every combination of every row. I doubt this is what you want.

Something like this may help get you started...

SELECT
  CASE WHEN inserted.primaryKey IS NULL THEN 'This is a delete'
       WHEN  deleted.primaryKey IS NULL THEN 'This is an insert'
                                        ELSE 'This is an update'
  END  as Action,
  *
FROM
  inserted
FULL OUTER JOIN
  deleted
    ON inserted.primaryKey = deleted.primaryKey

Depending on what you want to do, you then reference the table you are interested in with inserted.userID or deleted.userID, etc.

Finally, be aware that inserted and deleted are tables and can (and do) contain more than one record.

If you insert 10 records at once, the inserted table will contain ALL 10 records. The same applies to deletes and the deleted table. And both tables in the case of an update.

EDIT Examplee Trigger after OPs edit.

ALTER TRIGGER [dbo].[UpdateUserCreditsLeft] 
  ON  [dbo].[Order]
  AFTER INSERT,UPDATE,DELETE
AS 
BEGIN

  -- SET NOCOUNT ON added to prevent extra result sets from
  -- interfering with SELECT statements.
  SET NOCOUNT ON;

  UPDATE
    User
  SET
    CreditsLeft = CASE WHEN inserted.UserID IS NULL THEN <new value for a  DELETE>
                       WHEN  deleted.UserID IS NULL THEN <new value for an INSERT>
                                                    ELSE <new value for an UPDATE>
                  END
  FROM
    User
  INNER JOIN
    (
      inserted
    FULL OUTER JOIN
      deleted
        ON inserted.UserID = deleted.UserID  -- This assumes UserID is the PK on UpdateUserCreditsLeft
    )
      ON User.UserID = COALESCE(inserted.UserID, deleted.UserID)

END

If the PrimaryKey of UpdateUserCreditsLeft is something other than UserID, use that in the FULL OUTER JOIN instead.

Since I have encoding ISO-8859-1 operating system the date format "dd.MM.yyyy HH:mm:sss" was not recognised what did work was to use InvariantCulture string.

string url = "GetData?DagsPr=" + DagsProfs.ToString(CultureInfo.InvariantCulture)

add app:elevation="0dp" in AppBarLayout for hiding shadow in appbar

jQuery

$('head').append( ... );

JavaScript:

document.getElementsByTagName('head')[0].appendChild( ... );

XPath 2 has a lower-case (and upper-case) string function. That's not quite the same as case-insensitive, but hopefully it will be close enough:

//CD[lower-case(@title)='empire burlesque']

If you are using XPath 1, there is a hack using translate.

It might be easier to use JavaScript or jquery for this. Assuming that the height of the header and the footer is 200 then the code will be:

function SetHeight(){
    var h = $(window).height();
    $("#inner-right").height(h-200);    
}

$(document).ready(SetHeight);
$(window).resize(SetHeight);

The problem occurs because webpack-dev-server 2.4.4 adds a host check. You can disable it by adding this to your webpack config:

 devServer: {
    compress: true,
    disableHostCheck: true,   // That solved it

 }      

EDIT: Please note, this fix is insecure.

Please see the following answer for a secure solution: https://stackoverflow.com/a/43621275/5425585

using jQuery

 $("#ddl").change(function () {
                alert($(this).val());
            });

jsFiddle

public static void GoToSite(string url)
{
     System.Diagnostics.Process.Start(url);
}

that should solve your problem

To trigger an event you basically just call the event handler for that element. Slight change from your code.

var a = document.getElementById("element");
var evnt = a["onclick"];

if (typeof(evnt) == "function") {
    evnt.call(a);
}

One line working answer:

$url = "http://www.yoursite/one/two/three/drink";
echo $end = end((explode('/', $url)));

Output: drink

I just want to mention a thing, there are many tools can do text processing, e.g. sort, cut, split, join, paste, comm, uniq, column, rev, tac, tr, nl, pr, head, tail.....

they are very handy but you have to learn their options etc.

A lazy way (not the best way) to learn text processing might be: only learn grep , sed and awk. with this three tools, you can solve almost 99% of text processing problems and don't need to memorize above different cmds and options. :)

AND, if you 've learned and used the three, you knew the difference. Actually, the difference here means which tool is good at solving what kind of problem.

a more lazy way might be learning a script language (python, perl or ruby) and do every text processing with it.

This is the most efficient way to get just the callers class. Other approaches take an entire stack dump and only give you the class name.

However, this class in under sun.* which is really for internal use. This means that it may not work on other Java platforms or even other Java versions. You have to decide whether this is a problem or not.

java.net.URLDecoder deals only with the application/x-www-form-urlencoded MIME format (e.g. "%20" represents space), not with HTML character entities. I don't think there's anything on the Java platform for that. You could write your own utility class to do the conversion, like this one.

As far as I know there is no built in svn command to accomplish this. You would need to write a script to run several commands to build all the diffs. A simpler approach would be to use a GUI svn client if that is an option. Many of them such as the subversive plugin for Eclipse will list the history of a file as well as allow you to view the diff of each revision.

ul {
width: 90%; 
    list-style-type:none;
    margin:auto;
    padding:0;
    position:relative;
    left:5%;
}

If you want to see data updates you could use this technique with required permissions:

SELECT OBJECT_NAME(OBJECT_ID) AS DatabaseName, last_user_update,*
FROM sys.dm_db_index_usage_stats
WHERE database_id = DB_ID( 'DATABASE')
AND OBJECT_ID=OBJECT_ID('TABLE')

Add this path in your Environment Variables PATH C:\Users\USERNAME\AppData\Roaming\npm\

This will work. This is your directory name "Directory_Name"

 sudo code --user-data-dir="Directory_Name"

I think this might help...

In order to break down user inputted dates (mm/dd/yyyy) in my scripts, I store the day, month, and year into an array, and then put the values into separate variables as follows:

DATE_ARRAY=(`echo $2 | sed -e 's/\// /g'`)
MONTH=(`echo ${DATE_ARRAY[0]}`)
DAY=(`echo ${DATE_ARRAY[1]}`)
YEAR=(`echo ${DATE_ARRAY[2]}`)

This is usually simply due to mismatching times between your host and client machines. You can try to synchronize the times on your machines using ntp.

You can just add the DISTINCT(ip), but it has to come at the start of the query. Be sure to escape PHP variables that go into the SQL string.

SELECT DISTINCT(ip), name, COUNT(name) nameCnt, 
time, price, SUM(price) priceSum
FROM tablename 
WHERE time >= $yesterday AND time <$today 
GROUP BY ip, name

First, I see you're using an explicit $.parseJSON(). If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.

To iterate through the first item in the array you've got there, use code like this:

var firstItem = response.d[0];

for(key in firstItem) {
  console.log(key + ':' + firstItem[key]);
}

If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d and then use this code inside that outer loop.

Actually got the same problem. For me worked this easy way:

Adding the data to a Datatable and sort it:

dt.DefaultView.Sort = "columnname";
dt = dt.DefaultView.ToTable();

Try this!

package your.package;

import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateUtil
{
    private static SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;

    static
    {
        try
        {
//          Configuration configuration = new Configuration();
            Configuration configuration = new Configuration().configure();

            serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
            sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        }
        catch (HibernateException he)
        {
            System.err.println("Error creating Session: " + he);
            throw new ExceptionInInitializerError(he);
        }
    }

    public static SessionFactory getSessionFactory()
    {
        return sessionFactory;
    } 
}

It's something that "appears to the rest of the system to occur instantaneously", and falls under categorisation of Linearizability in computing processes. To quote that linked article further:

Atomicity is a guarantee of isolation from concurrent processes. Additionally, atomic operations commonly have a succeed-or-fail definition — they either successfully change the state of the system, or have no apparent effect.

So, for instance, in the context of a database system, one can have 'atomic commits', meaning that you can push a changeset of updates to a relational database and those changes will either all be submitted, or none of them at all in the event of failure, in this way data does not become corrupt, and consequential of locks and/or queues, the next operation will be a different write or a read, but only after the fact. In the context of variables and threading this is much the same, applied to memory.

Your quote highlights that this need not be expected behaviour in all instances.

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

this works for me :

1- add class for each row "removeRow"

2- in the jQuery

$(".removeRow").remove();

Use

var_dump($this->input->post());

Please see the screen shot. Here I am priniting all the post array value

Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

I'll answer for horizontal stretching of text, since the vertical is the easy part - just use "transform: scaleY()"

.stretched-text {
  letter-spacing: 2px;
  display: inline-block;
  font-size: 32px;
  transform: scaleY(0.5);
  transform-origin: 0 0;
  margin-bottom: -50%;
}
span {
  font-size: 16px;
  vertical-align: top;
}

<span class="stretched-text">this is some stretched text</span>
<span>and this is some random<br />triple line <br />not stretched text</span>

letter-spacing just adds space between letters, stretches nothing, but it's kinda relative

inline-block because inline elements are too restrictive and the code below wouldn't work otherwise

Now the combination that makes the difference

font-size to get to the size we want - that way the text will really be of the length it's supposed to be and the text before and after it will appear next to it (scaleX is just for show, the browser still sees the element at its original size when positioning other elements).

scaleY to reduce the height of the text, so that it's the same as the text beside it.

transform-origin to make the text scale from the top of the line.

margin-bottom set to a negative value, so that the next line will not be far below - preferably percentage, so that we won't change the line-height property. vertical-align set to top, to prevent the text before or after from floating to other heights (since the stretched text has a real size of 32px)

-- The simple span element has a font-size, only as a reference.

The question asked for a way to prevent the boldness of the text caused by the stretch and I still haven't given one, BUT the font-weight property has more values than just normal and bold.

I know, you just can't see that, but if you search for the appropriate fonts, you can use the more values.

Choose & memorize 1 of the following!!! :)

[\s\S]*
[\w\W]*
[\d\D]*

Explanation:

\s: whitespace \S: not whitespace

\w: word \W: not word

\d: digit \D: not digit

(You can exchange the * for + if you want 1 or MORE characters [instead of 0 or more]).

BONUS EDIT:

If you want to match everything on a single line, you can use this:

[^\n]+

Explanation:

^: not

\n: linebreak

+: for 1 character or more

<div ng-controller="ExampleController">
  <form name="myForm">
    <label for="repeatSelect"> Repeat select: </label>
    <select name="repeatSelect" id="repeatSelect" ng-model="data.model">
      <option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
    </select>
  </form>
  <hr>
  <tt>model = {{data.model}}</tt><br/>
</div>

AngularJS:

angular.module('ngrepeatSelect', [])
 .controller('ExampleController', ['$scope', function($scope) {
   $scope.data = {
    model: null,
    availableOptions: [
      {id: '1', name: 'Option A'},
      {id: '2', name: 'Option B'},
      {id: '3', name: 'Option C'}
    ]
   };
}]);

The easiest way would be to use a GUI:

For Gnome use gnome-schedule (universe)

sudo apt-get install gnome-schedule 

For KDE use kde-config-cron

It should be pre installed on Kubuntu

But if you use a headless linux or don´t want GUI´s you may use:

crontab -e

If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:

*     *     *     *     *  YOURCOMMAND
-     -     -     -     -
|     |     |     |     |
|     |     |     |     +----- Day in Week (0 to 7) (Sunday is 0 and 7)
|     |     |     +------- Month (1 to 12)
|     |     +--------- Day in Month (1 to 31)
|     +----------- Hour (0 to 23)
+------------- Minute (0 to 59)

There are some shorts, too (if you don´t want the *):

@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year

If you want to use the shorts as cron (because they don´t work or so):

@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *

I know that this post is a bit old but incase anyone finds it still relevant you might want to check out the free geocoding services offered by USC College. This does included address validation via ajax and static calls. The only catch is that they request a link back and only offer allotments of 2500 calls. More than fair. https://webgis.usc.edu/Services/AddressValidation/Default.aspx

Strictly speaking, you should put something that makes sense - according to the spec here, the most correct version is:

<input name=name id=id type=checkbox checked=checked>

For HTML, you can also use the empty attribute syntax, checked="", or even simply checked (for stricter XHTML, this is not supported).

Effectively, however, most browsers will support just about any value between the quotes. All of the following will be checked:

<input name=name id=id type=checkbox checked>
<input name=name id=id type=checkbox checked="">
<input name=name id=id type=checkbox checked="yes">
<input name=name id=id type=checkbox checked="blue">
<input name=name id=id type=checkbox checked="false">

And only the following will be unchecked:

<input name=name id=id type=checkbox>

See also this similar question on disabled="disabled".

Another form that works with Postgres 9.1+ is combining a Common Table Expression with the USING statement for the join.

WITH prod AS (select m_product_id, upc from m_product where upc='7094')
DELETE FROM m_productprice B
USING prod C
WHERE B.m_product_id = C.m_product_id 
AND B.m_pricelist_version_id = '1000020';

(I do realise the question is old, but it's among the top hits on Google.)

A common situation where you want to know the response code is in exception handling. As of C# 7, you can use pattern matching to actually only enter the catch clause if the exception matches your predicate:

catch (WebException ex) when (ex.Response is HttpWebResponse response)
{
     doSomething(response.StatusCode)
}

This can easily be extended to further levels, such as in this case where the WebException was actually the inner exception of another (and we're only interested in 404):

catch (StorageException ex) when (ex.InnerException is WebException wex && wex.Response is HttpWebResponse r && r.StatusCode == HttpStatusCode.NotFound)

Finally: note how there's no need to re-throw the exception in the catch clause when it doesn't match your criteria, since we don't enter the clause in the first place with the above solution.

For me ony granting 'Read' permissions for 'NetworkService' to the whole 'EventLog' branch worked.

Also you can use f-string formatting to write integer to file

For appending use following code, for writing once replace 'a' with 'w'.

for i in s_list:
    with open('path_to_file','a') as file:
        file.write(f'{i}\n')

file.close()

as much as everyone hates tables for layout, they do help with stuff like this, either using explicit table tags or using display:table-cell

<div style="width:300px; display:table">
    <label for="MyInput" style="display:table-cell; width:1px">label&nbsp;text</label>
    <input type="text" id="MyInput" style="display:table-cell; width:100%" />
</div>

Sending data to some service page.

<form class="form-horizontal" role="form" ng-submit="submit_form()">
    <input type="text" name="user_id" ng-model = "formAdata.user_id">
    <input type="text" id="name" name="name" ng-model = "formAdata.name">
</form>

$scope.submit_form = function()
            {
                $http({
                        url: "http://localhost/services/test.php",
                        method: "POST",
                        headers: {'Content-Type': 'application/x-www-form-urlencoded'},
                        data: $.param($scope.formAdata)
                    }).success(function(data, status, headers, config) {
                        $scope.status = status;
                    }).error(function(data, status, headers, config) {
                        $scope.status = status;
                    });
            }

So this question is nearly 10 years old, but it popped up on one of my searches, and I think that there are better solutions when programming in Qt: Signals & slots, timers, and finite state machines. The delays that are required can be implemented without sleeping the application in a way that interrupts other functions, and without concurrent programming and without spinning the processor - the Qt application will sleep when there are no events to process.

A hack for this is to have a sequence of timers with their timeout() signal connected to the slot for the event, which then kicks off the second timer. This is nice because it is simple. It's not so nice because it quickly becomes difficult to troubleshoot and maintain if there are logical branches, which there generally will be outside of any toy example.

QTimer

A better, more flexible option is the State Machine infrastructure within Qt. There you can configure an framework for an arbitrary sequence of events with multiple states and branches. An FSM is much easier to define, expand and maintain over time.

Qt State Machine

Font myFont = new Font("Serif", Font.BOLD, 12);, then use a setFont method on your components like

JButton b = new JButton("Hello World");
b.setFont(myFont);

Stop abusing private fields!!!

The comments here seem to be overwhelmingly supportive towards using private fields. Well, then I have something different to say.

Are private fields good in principle? Yes. But saying that a golden rule is make everything private when you're not sure is definitely wrong! You won't see the problem until you run into one. In my opinion, you should mark fields as protected if you're not sure.

There are two cases you want to extend a class:

• You want to add extra functionality to a base class
• You want to modify existing class that's outside the current package (in some libraries perhaps)

There's nothing wrong with private fields in the first case. The fact that people are abusing private fields makes it so frustrating when you find out you can't modify shit.

Consider a simple library that models cars:

class Car {
    private screw;
    public assembleCar() {
       screw.install();
    };
    private putScrewsTogether() {
       ...
    };
}

The library author thought: there's no reason the users of my library need to access the implementation detail of assembleCar() right? Let's mark screw as private.

Well, the author is wrong. If you want to modify only the assembleCar() method without copying the whole class into your package, you're out of luck. You have to rewrite your own screw field. Let's say this car uses a dozen of screws, and each of them involves some untrivial initialization code in different private methods, and these screws are all marked private. At this point, it starts to suck.

Yes, you can argue with me that well the library author could have written better code so there's nothing wrong with private fields. I'm not arguing that private field is a problem with OOP. It is a problem when people are using them.

The moral of the story is, if you're writing a library, you never know if your users want to access a particular field. If you're unsure, mark it protected so everyone would be happier later. At least don't abuse private field.

I very much support Nick's answer.

Alternatively, you can use the method int integerValue = (int)Math.round(double a);

There simply is no console listening by default. Running in debug mode there is a console attached, but in a production environment it is as you suspected, the message just doesn't go anywhere because nothing is listening.

You can use element.scrollTop and element.scrollLeft to get the vertical and horizontal offset, respectively, that has been scrolled. element can be document.body if you care about the whole page. You can compare it to element.offsetHeight and element.offsetWidth (again, element may be the body) if you need percentages.

I have had to do this several times and have researched many different solutions.

The solution I find in most elegant and easy to accomplish can be implemented as such.

1. Create a project that you can create a simple interface

the interface will contain signatures of any members you wish to call.

public interface IExampleProxy
{
    string HelloWorld( string name );
}

Its important to keep this project clean and lite. It is a project that both AppDomain's can reference and will allow us to not reference the Assembly we wish to load in seprate domain from our client assembly.

2. Now create project that has the code you want to load in seperate AppDomain.

This project as with the client proj will reference the proxy proj and you will implement the interface.

public interface Example : MarshalByRefObject, IExampleProxy
{
    public string HelloWorld( string name )
    {
        return $"Hello '{ name }'";
    }
}

3. Next, in the client project, load code in another AppDomain.

So, now we create a new AppDomain. Can specify the base location for assembly references. Probing will check for dependent assemblies in GAC and in current directory and the AppDomain base loc.

// set up domain and create
AppDomainSetup domaininfo = new AppDomainSetup
{
    ApplicationBase = System.Environment.CurrentDirectory
};

Evidence adevidence = AppDomain.CurrentDomain.Evidence;

AppDomain exampleDomain = AppDomain.CreateDomain("Example", adevidence, domaininfo);

// assembly ant data names
var assemblyName = "<AssemblyName>, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null|<keyIfSigned>";
var exampleTypeName = "Example";

// Optional - get a reflection only assembly type reference
var @type = Assembly.ReflectionOnlyLoad( assemblyName ).GetType( exampleTypeName ); 

// create a instance of the `Example` and assign to proxy type variable
IExampleProxy proxy= ( IExampleProxy )exampleDomain.CreateInstanceAndUnwrap( assemblyName, exampleTypeName );

// Optional - if you got a type ref
IExampleProxy proxy= ( IExampleProxy )exampleDomain.CreateInstanceAndUnwrap( @type.Assembly.Name, @type.Name );    

// call any members you wish
var stringFromOtherAd = proxy.HelloWorld( "Tommy" );

// unload the `AppDomain`
AppDomain.Unload( exampleDomain );

if you need to, there are a ton of different ways to load an assembly. You can use a different way with this solution. If you have the assembly qualified name then I like to use the CreateInstanceAndUnwrap since it loads the assembly bytes and then instantiates your type for you and returns an object that you can simple cast to your proxy type or if you not that into strongly-typed code you could use the dynamic language runtime and assign the returned object to a dynamic typed variable then just call members on that directly.

There you have it.

This allows to load an assembly that your client proj doesnt have reference to in a seperate AppDomain and call members on it from client.

To test, I like to use the Modules window in Visual Studio. It will show you your client assembly domain and what all modules are loaded in that domain as well your new app domain and what assemblies or modules are loaded in that domain.

The key is to either make sure you code either derives MarshalByRefObject or is serializable.

`MarshalByRefObject will allow you to configure the lifetime of the domain its in. Example, say you want the domain to destroy if the proxy hasnt been called in 20 minutes.

I hope this helps.

For example:

import subprocess

subprocess.call("C:\helloworld.py")

subprocess.call(["python", "-h"])

AngularJS – Isolated Scopes – @ vs = vs &

Short examples with explanation are available at below link :

http://www.codeforeach.com/angularjs/angularjs-isolated-scopes-vs-vs

@ – one way binding

In directive:

scope : { nameValue : "@name" }

In view:

<my-widget name="{{nameFromParentScope}}"></my-widget>

= – two way binding

In directive:

scope : { nameValue : "=name" },
link : function(scope) {
  scope.name = "Changing the value here will get reflected in parent scope value";
}

In view:

<my-widget name="{{nameFromParentScope}}"></my-widget>

& – Function call

In directive :

scope : { nameChange : "&" }
link : function(scope) {
  scope.nameChange({newName:"NameFromIsolaltedScope"});
}

In view:

<my-widget nameChange="onNameChange(newName)"></my-widget>

This will increase any date by exactly one

String untildate="2011-10-08";//can take any date in current format    
SimpleDateFormat dateFormat = new SimpleDateFormat( "yyyy-MM-dd" );   
Calendar cal = Calendar.getInstance();    
cal.setTime( dateFormat.parse(untildate));    
cal.add( Calendar.DATE, 1 );    
String convertedDate=dateFormat.format(cal.getTime());    
System.out.println("Date increase by one.."+convertedDate);

I think your best bet is going to be to convert those lists into something parcelable such as a string (or map?) to get it to the Activity. Then the Activity will have to convert it back to an array.

Implementing custom parcelables is a pain in the neck IMHO so I would avoid it if possible.

A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.

If you want to control the width of your data, then you could use the width sub-specifiers in the printf format string. Eg. :

printf("%5d", 2);

It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.

If you want complete control, you'll probably have to implement it yourself.

Just note the difference between the range operators:

3..10  # includes 10
3...10 # doesn't include 10

Orabig is correct.

You can bind 10.0.2.15 in Ubuntu (VirtualBox) then do a port forwarding from host to guest Ubuntu.

in /etc/redis/redis.conf

bind 10.0.2.15

then, restart redis:

sudo systemctl restart redis

It shall work!

Alternative without using cut2.

das$wt2 <- as.factor( as.numeric( cut(das$wt,3)))

or

das$wt2 <- as.factor( cut(das$wt,3, labels=F))

As pointed out by @ben-bolker this splits into equal-widths rather occupancy. I think that using quantiles one can approximate equal-occupancy

x = rnorm(10)
x
 [1] -0.1074316  0.6690681 -1.7168853  0.5144931  1.6460280  0.7014368
 [7]  1.1170587 -0.8503069  0.4462932 -0.1089427
bin = 3 #for 1/3 rd, 4 for 1/4, 100 for 1/100th etc
xx = cut(x, quantile(x, breaks=1/bin*c(1:bin)), labels=F, include.lowest=T)
table(xx)
1 2 3 4
3 2 2 3

You can use Sys.time(). However, when you record the time difference in a table or a csv file, you cannot simply say end - start. Instead, you should define the unit:

f_name <- function (args*){
start <- Sys.time()
""" You codes here """
end <- Sys.time()
total_time <- as.numeric (end - start, units = "mins") # or secs ... 
}

Then you can use total_time which has a proper format.

In iOS9 UIPopoverController is depreciated. So can use the below code for Objective-C version above iOS9.x,

- (IBAction)onclickPopover:(id)sender {
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
UIViewController *viewController = [sb instantiateViewControllerWithIdentifier:@"popover"];

viewController.modalPresentationStyle = UIModalPresentationPopover;
viewController.popoverPresentationController.sourceView = self.popOverBtn;
viewController.popoverPresentationController.sourceRect = self.popOverBtn.bounds;
viewController.popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirectionAny;
[self presentViewController:viewController animated:YES completion:nil]; }

According to the certification exam you should use Convert.ToXXX() whenever possible for simple conversions because it optimizes performance better than CXXX conversions.

Just add background-attachment to your code

body {
    background-position: center;
    background-image: url(../images/images5.jpg);
    background-attachment: fixed;
}

if the database is maintained by you then simply create a new database and import the data from the old one. the collation problem is solved!!!!!

Sure there is! For instance:

<xsl:if test="not(contains($hhref, '1234'))">
  <li>
    <a href="{$hhref}" title="{$pdate}">
      <xsl:value-of select="title"/>
    </a>
  </li>
</xsl:if>

The syntax is: contains(stringToSearchWithin, stringToSearchFor)

Alternatively, you could invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

I liked this example.

I used the

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ScrollView01"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<RelativeLayout

and works perfectly
