scrollTop get each pixel

Vote count:

0

When I use the function scrollTop to get the amount of pixels of the top I receive 1, 4, 20,... depending on the speed that I am scrolling.

$(window).scroll(function(){
    var position = $(document).scrollTop();
    console.log(position);
)};

I am building a site were I need to get each pixel. This because I am checking when a certain position-value is showing. For example:

if(position === 1200){
    // do something
}

Now this is not possible with the values I receive of the scrollTop function. Now I'am using this code below which make it possible to calculate each pixel, but this is only working smooth when the site is not to heigh. If the site is more then 3000px of height, it will begin to jitter because it takes to lang to calculate the pixel.

var viewportFirstPosition = $(document).scrollTop();
$(window).scroll(function(){
    var inc;

    var viewportHeight = $(window).height();
    var viewportNewPosition = $(document).scrollTop();

    if(viewportNewPosition > viewportFirstPosition){
       inc=1;
    }
    else{
       inc=-1;
    }

    while(viewportFirstPosition !== viewportNewPosition){
        viewportFirstPosition += inc;
        console.log(viewportFirstPosition); // 1, 2, 3, 4, 5, ...
    }
}

Any ideas how I can do it differently? Without the jitter :) Thanks!

Filter Results in AngularJS

I have ng-click in my view, which is supposed to filter my presented results.

<a role="menuitem" tabindex="-1" href ng-click="itemFilter=itemABCFilter">ABC Filter</a>

All items from ABC are stored in my controller, such as

$scope.itemABC=["Alpha","Beta","Gamma"];

A list of all items in my view come from a $http request I made. No I seek loop through all data.item (my data I obtained from the get request) and find out whether it contains any element of itemABC or can be considered as a substring of any of the elements of itemABC it.

  $scope.itemABCfilter=function(data){
    for (var j=0; j<$scope.itemABC.length;j++){
      if($scope.itemABC[j].search($scope.data[i].name)>-1) return true;
    }

Somehow the code above does not filter my results. Do I handle the $http request results not correctly or is the code simply wrong? How would ou do it?

Thanks

tfs build is getting failed when releasebuild is true

Vote count:

I am working on triggering release from TFS build and I have configured Release Management environment for the same.

TFS build is not successful when I make "ReleaseBuild=true". Error count is zero even though the build is getting failed. From some of the articles, I came to know that build agent account should be created as "Release Manager" in RM client. Now Build Agent is running under NETWORK SERVICES account.

I have few doubts:

1. Do I need to change Build Agent identity to windows identity and create that user as release manager in RM client?


2. If yes, what are the necessary permissions to be given for that account in both windows and in RM.


3. If No, how I could create NETWORK SERVICES as “release manager” in RM

Please help me to resolve this road blocking issue.

How to create a join_table with a specific table name? (RAILS)

I have been given the unenviable task of moving from Postgres to Oracle. (Very very sad. Not my call). When I run rake db:migrate, rails throws an Oracle error ORA-00972: identifier is too long. How can I specify the table_name in the migration so that it is less than the 30 character limit imposed by Oracle?

The following is an example taken from: http://ift.tt/1vvO7C0

and yields a table name: products_categories

class CreateJoinTableProductsCategories < ActiveRecord::Migration def change create_join_table :products, :categories do |t| # t.index [:product_id, :category_id] # t.index [:category_id, :product_id] end end end

I want to do something like this, specifying the join_table name, to yield the join table name of "myjointablename":

class CreateJoinTableProductsCategories < ActiveRecord::Migration def change create_join_table :products, :categories, table_name: :myjointablename do |t| # t.index [:product_id, :category_id] # t.index [:category_id, :product_id] end end end

Interface between 2 java Applications - How to use path to second application

Vote count:

0

I am writing an interface between 2 java applications. Application 1 is built on top of an Eclipse RCP framework, and is the starting point of my interface. The code I am writing is built within a plugin and loaded via an update site into Application 1. (fairly happy with this part).

My issue then is how to reference the 2nd Application from within this plugin.

Currently, for development I have bundled all of the Application 2 JARs into a separate project, and then referenced this bundled project from my development plugins for Application 1. This works inside Eclipse, but has numerous problems when trying to include this as part of the update site. Not least of which is that the JARs don't belong to us, and therefore re-packaging and distributing them is a no-no.

In my deployed environment, I can assume that Application 2 will be installed on the client machine, along with the required JARs, but I don't necessarily know where they will be installed, or what version they will have.

So I see a number of options, but whether they are correct or not I don't have the experience in deploying Java applications to be able to tell.

Options:

1. Update command line for Application 1 to specify the classpath for JARs for Application 2.


2. Use Preferences window inside Application 1 (because this is based on Eclipse RCP), and create a customised ClassLoader for the JARs in Application 2.


3. Create a cut-down version of the bundled JARs for Application 2 and deploy these through the update site (I have been trying this, but have hit the wall again, and can't help feeling there is a better way).

A secondary question for my plugin development is, How can I tell 'nicely' whether Application 2 is configured and installed ? so that I can gracefully exit my plugin, and perhaps give the user a nice message.

Javascript POST to PHP page

Vote count:

0

My goal is to establish where a page was opened via a javascript pop up, and carry a related URTL varialble through to other page(s). Originally I thought I could do this with a URL variable however as java runs client side and php is server side there is no way to verify whether the window is a java windopw especially given the possibility that someone returned on a favorite or bookmark

I originally made a similar post to this however as the idea has evolved and being stuck with the variable in the URL, this may be a better approach

I think I have figured out the basics but the mechanics involve javascript that I am not so familiar with.

Here is what I have in a page right now

<script>
function PopupCenter(pageURL, title,w,h) {
var left = (screen.width/2)-(w/2);
var top = (screen.height/2)-(h/2);
var targetWin = window.open (pageURL, title, 'toolbar=no, location=no, directories=no, status=no,  menubar=no, scrollbars=yes, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+top+', left='+left);
}
</script>

<a onclick="PopupCenter('/customconfig/index.php, 'CustomBuilder1',1080,700);" href="javascript:void(0);"> <img border=0  src = "/images/Animated.GIF"></a>

Now I found this page http://ift.tt/1rDC1Ed

which tells me how to pot a POST in a javascrip with this code

<script>
function postwith (to,p) { 
var myForm = document.createElement("form");
myForm.method="post" ;
myForm.action = to ;
for (var k in p) {
var myInput = document.createElement("input") ;
myInput.setAttribute("name", k) ;
myInput.setAttribute("value", p[k]);
myForm.appendChild(myInput) ;
}
document.body.appendChild(myForm) ;
myForm.submit() ;
document.body.removeChild(myForm) ;
}
</script>

Of course the advantage of this method is that there is no URL variable when I go to the first page and I can also carry the POST value through all php pages.

My biggest question is how to merge the code for loading the centered javascript window with the code for passing the POST variable, and making them work "happy together"

This means that if someone goes back on a bookmark or favorite the POST value will be NULL, and I can carry that NULL value through the subsequent page(s) as a POST hidden value

Thanks,

Mark

Building a logical tree for a custom control

Vote count:

0

I'm working on a control that has an ObservableCollection as one of its DependencyProperties. This property is set as the DefaultProperty for my control, so I can implicitly add items to the collection in XAML by constructing lines similar to the following:

<MyControl>
    <MyItem/>
    <MyItem/>
    <MyItem/>
</MyControl>

As far as I understand, the WPF engine builds the logical tree when it parses through the XAML. Therefore, each MyItem should be a logical child of the MyControl. Conversely, the MyControl should be the logical parent of each MyItem.

Well, apparently there is more to it. Below is the code that I use to define the relationship above. The custom control contains a DependencyProperty for the ObservableCollection and it is backed by a CLR-property.

[ContentProperty("Items")]
public class MyControl : Control
{
    public static readonly DependencyProperty ItemsProperty = DependencyProperty.Register(
        "Items", 
        typeof(ObservableCollection<MyItem>), 
        typeof(MyControl), 
        new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.AffectsRender, OnItemsChangedProperty));

    [Category("MyControl")]
    public ObservableCollection<MyItem> Items
    {
        get { return (ObservableCollection<MyItem>)GetValue(ItemsProperty); }
        set { SetValue(ItemsProperty, value); }
    }

    public MyControl() : base()
    {   //Set a new collection per control, but don't destroy binding.
        SetCurrentValue(ItemsProperty, new ObservableCollection<MyItem>());
    }
}

From with the MyItem (which inherits FrameworkContentElement), I attempt to access its logical parent like so:

if (Parent is FrameworkElement)
{    //Re-Render the parent control.
    ((FrameworkElement)Parent).InvalidateVisual();
}

To my surprise, the parent control is never re-rendered. This is because the MyItem.Parent property is null. Why is this?

How can I instruct the WPF engine to know that MyControl should be the logical parent to MyItem?

Overlapping Perlin Noise

Vote count:

0

I have a perlin noise function, and I want to use it to pick biomes for a map for my game. The problem is that biomes are determined by two factors - average precipitation and average temperature. So, I thought, I'd just make two perlin noise functions and overlap them.

The issue now is that biomes do not encompass all possible precipitation temperature combinations. For example, there is no biome with high precipitation and low temperature, as shown in this picture.

How can I still use perlin noise but never reach the areas that aren't covered by biomes?

Copy offset to notepad when hex value is "xx" in .bin file

Vote count:

So I have a .bin file (16.5mb) that I would like to search through finding Hex values that I will pre-define in a textbox and copy the offset where the hex value is located into notepad for later use. And repeat this for the entire file.

So far I can load the .bin with button1, textbox1 and OFD. I would rather search only for the Hex value I specify with textbox2 and button2. If it is easier or faster to search for bytes I can enter the hex in as byte equivalent.

I found this which is similar= VB.Net Get Offset Address but no luck configuring it to my needs. Searching for Hex values would be ideal. This looks helpful however.

 Dim pos As Integer = 0 ' <== THIS IS THE OFFSET
    Dim length As Integer = reader.BaseStream.Length
    Do While pos < length
        ' Read the integer.
        Dim value As Byte = reader.ReadByte()
        If value = CByte(&H41) Then
            Return pos
            Exit Do
        End If
        ' Add length of integer in bytes to position.
        pos += 1
    Loop
End Using

Can someone suggest a good way of accomplishing this? Please and Thank you.

Let me tell ya, so much help here, my skill set is rapidly increasing. Thank you all for your help!!

MSSMS 2008 R2 Database is SQL 2008 SP1

However, I'm stuck. I've looked for an answer, but can't seem to find subtracting time in the same table from two different rows of the same table that fits. I'm having a difficult time with the following query. In the table below, I want to differentiate the TimeOut from one row to the TimeIn of the next row. Consider in the following table of finding the difference in minutes between the TimeOut in Row 1 (10:35am) and the TimeIn in Row 2 (10:38am).

Table 1: TIMESHEET

ROW    EmpID       TimeIn                   TimeOut
1       138         2014-01-05 10:04:00      2014-01-05 10:35:00   
2       138         2014-01-05 10:38:00      2014-01-05 10:59:00 
3       138         2014-01-05 11:05:00      2014-01-05 11:30:00  

Expected results

ROW    EmpID       TimeIn                   TimeOut                  Minutes
1       138         2014-01-05 10:04:00      2014-01-05 10:35:00       
2       138         2014-01-05 10:38:00      2014-01-05 10:59:00       3
3       138         2014-01-05 11:05:00      2014-01-05 11:30:00       6
etc
etc
etc

Basically, I need to differentiate the times in the query to show how long employees where on break. I've tried doing a join, but that doesn't seem to work and I don't know if OVER with PARTITION is the way to go, because I cannot seem to follow the logic (Yeah, I'm still learning). I also considering two temp tables and comparing them, but that doesn't work when I start changing days or employee ID's. Finally, I am thinking maybe LEAD in an OVER statement? Or is it just simple to do a DATEDIFF with a CAST?

Any help would be greatly appreciated!! Thanks in advance.

Make JavaScript event handler depend on AJAX response

Vote count:

0

A JavaScript beginner here :) I am trying to write a Web photo viewer where faces would be marked on the photos. To switch between photos, I'd like to use AJAX. My PHP script returns the name of the picture file and the coordinates of faces (x, y, radius) in the form of a JSON string, e.g.

{"filename":"im1.jpg","faces":[{"x":129,"y":260,"radius":40},{"x":232,"y":297,"radius":40}]} 

I want to draw circles on a canvas, based on faces, once the mouse is over the photo. Therefore I created a listener for the mouseover event. The problem is that if I add the listener after the AJAX call, the canvas gets multiple listeners and keeps drawing circles from the previous photos. So it looks like the handler needs to be defined in advance. But then I am struggling to pass the AJAX response to it. How could I achieve it?

My HTML code so far looks like this:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<canvas id="canvas" width="100" height="600"
    style="background-size: 100% 100%; border: 1px solid #FF0000;"></canvas>
<script>
    var image = new Image();
    var canvas = document.getElementById("canvas");
    var context = canvas.getContext("2d");

    function loadXMLDoc() {

        var xmlhttp;
        if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        }
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                var ajaxData = JSON.parse(xmlhttp.responseText);
                image.src = ajaxData.filename;
                image.onload = function() {
                    canvas.width = Math.round(canvas.height / image.height * image.width);
                    canvas.style.backgroundImage = "url('" + image.src + "')";
                }
                var faces = ajaxData.faces;
                canvas.addEventListener('mouseout', function(evt) {
                    context.clearRect(0, 0, canvas.width, canvas.height);
                    console.log("Canvas cleared");
                }, false);

                canvas.addEventListener('mouseover', function(evt) {
                    console.log("Canvas entered");
                    console.log("Faces to mark: " + faces.length);

                    for (i = 0; i < faces.length; i++) {
                        context.beginPath();
                        context.arc(faces[i].x, faces[i].y,

                        context.strokeStyle = "#00BBBB";
                        context.lineWidth = 1;
                        context.stroke();
                    }

I have an assignment to create a login & registering etc system. The solution must follow MVC architechture. My question is:

How can you use a Controller in PHP? I can't see how because there's no way to call specific functions in the controller from a form, the form action must be a php file. Since the form action must be a php file, I can't choose which function to execute, unless I use ifs to find the right function to execute. But that doesn't seem like a good solution.

Partitioning wide rows in Spark / Cassandra

Vote count:

0

Let's assume we have a Cassandra cluster with RF = N and a table containing wide rows.

Our table could have an index something like this: pk / ck1 / ck2 / ....

If I create an RDD from the table as follows:

val wide_row = sc.cassandraTable(KS, TABLE).select("c1", "c2").where("pk = ?", PK)

I notice that one Spark node has 100% of the table and the others have none. I assume this is because the spark-cassandra-connector has no way of breaking down the query token range into smaller sub ranges because it's actually not a range -- it's simply the hash of PK.

At this point we could simply call redistribute(N) to spread the data across the Spark cluster before processing, but this has the effect of moving data across the network to nodes that already have the data locally in Cassandra (remember RF = N)

What we would really like is to have each Spark node load a subset of the wide row locally from Cassandra.

One approach which came to mind is to generate an RDD containing the list of all values of the first cluster key (ck1) when pk = PK. We could then use mapPartitions() to load a slice of the wide row based on each value of ck1.

Assuming we already have our list values for ck1, we could write something like this:

val ck1_list = ....  // RDD

ck1_list.repartition(ck1_list.count().toInt) // create a partition for each value of ck1

val wide_row = ck1_list.mapPartitionsWithIndex(f) 

Within the partition iterator, f(), we would like to call another function g(pk, ck1) which loads the row slice from Cassandra for row key pk and column ck1. We could then apply flatMap to ck1_list so as to create a fully distributed RDD of the wide row without any shuffing.

So here's the question:

Is it possible to make a CQL call from within a Spark task? What driver should be used? Can it be set up only once an reused for subsequent tasks?

Any help would be greatly appreciated, thanks.

Single Method Web Service - Bad idea?

Vote count:

0

There has been some debate around a web service for a project. A few of the old school developers think a single method which accepts a generic object (a JSON string containing a method name and data which be serialized into different objects) is a good way of doing it. It'll work...but feels completely wrong.

Personally, I think this completely goes against the grain of a service and further down the line will spell trouble and headaches as the project grows/changes. I would prefer to go down a RESTful route or standard service method verb of "GetCustomerById", giving a Separation of Concern. Plus if we ever expose the service, the method names will mean something to external consumers.

The generic method touted will work perfectly fine, but I feel it just goes completely against the principle of SOA and services. Plus, I feel like I'm losing a battle against some old school ways of thinking - "it works though".

Are there any other pitfalls I can put forward to show that this will be a bad idea in the long run? I'm a advocate of patterns and practices, which can fall on deaf ears. Any pros and cons I can use would be appreciated.

How to add new object of model in a foreign controller

Vote count:

0

I am rather new to Rails.

I am working on a profile-page for a User. The show view is divided into partials. The thing about my modelling structure is, that a User can have a Skill. But the User model itself does not have a Skill related column, so all Skill entries are saved in the Skill model.

So, my question is, how can I include a partial into the User show view, that contains a simple add Skill form (name needed only), which saves that Skill into its own table and adds it to the others collection of User.skills?

PDO, output all data from a table

Vote count:

0

I have been trying to output data from a db table but I can't seem to do it, it doens't show up no matter what I do. I tried using foreach but no dice. This code was taken from a phpacademy tutorial and I am trying to modify it by adding a bit of functionality like being able to gather all data from the database using pdo

$bgItems = DB::getInstance()->getAll('background_image');

echo '<pre>', var_dump($bgItems), '</pre>';

foreach($bgItems as $bgItem) {
    echo $bgItem;
}

This is what the DB class looks like with the method i'm trying to implement: public function query($sql, $params = array()) {

$this->_error = false;
        if($this->_query = $this->_pdo->prepare($sql)) {
            $x = 1;
            if(count($params)) {
                foreach($params as $param) {
                    $this->_query->bindValue($x, $param);
                    $x++;
                }
            }

            if($this->_query->execute()) {
                $this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
                $this->_count = $this->_query->rowCount();
            } else {
                $this->_error = true;
            }
        }

        return $this;
    }

    public function action($action, $table, $where = array()) {
        if(count($where) === 3) { 
            $operators = array('=', '>', '<', '>=', '<=');

            $field      = $where[0];
            $operator   = $where[1];
            $value      = $where[2];

            if(in_array($operator, $operators)) {
                $sql = "{$action} FROM {$table} WHERE {$field} {$operator} ?";
                if(!$this->query($sql, array($value))->error()) {
                    return $this;
                }
            }
        }

        else {
            $sql = "{$action} FROM {$table}";
            if(!$this->query($sql)->error()) {
                return $this;
            }
        }

        return false;
    }

    public function getAll($table) {
        return $this->action('SELECT *', $table);
    }

And this is the output I get when trying to view the data retrieved using var_dump, which obviously looks like a complicated array.

object(DB)#3 (5) {

  object(PDO)#4 (0) {
  }

How to import csv which have lines that are ends with separate character?

Vote count:

11110|2005001|abc|apple|00|good|fine|2|||||0|||go|stop||20100520|

Above is an example of csv data.

I'm trying to import a csv into database table. But every line of the csv ends with separate character '|'.

I think that is why keep failing to import data.

I chose options like this :

partial import :                 uncheck;
format of imported file :        csv
option - fields terminated by :  |
option - fields enclosed by by :
option - field escaped by :      \
option - lines terminated by :   auto
option - column names : 

How can I import these csv files into db?

Can not delete the '|' at the end of the line.

Because there are more than 400,000 lines in csv file.

And I don't know regular expression and some of lines are ends with '|||' like this;;

Angular service calling another service

I'm making a simple Angular app to manage incomes. The incomes come from projects that I store in json (for testing purpose).

So, basically, I use a service in Angular to get this json and I would like to have another service that call Projects service and filter the incomes of each projects.

Here's the code :

facturateApp.service('Projects', function($http){     


 var Projects = {
      async: function() {

        var promise = $http.get('base.json').then(function (response) {            
          return response.data;
        });
        return promise;
      }
    };
    return Projects;


});

facturateApp.service('Incomes', function(Projects){    
    var incomes = []; 
    Projects.async().then(function(d) {
      var projects = d;

      angular.forEach(projects, function(project){

        if(typeof(project.account.accountAmount) == 'number' && project.account.accountAmount > 0){
            var newIncome = {};
            newIncome.projectName = project.projectName;
            newIncome.clientName = project.clientName;
            newIncome.typeIncome = "Accompte";
            newIncome.amount = project.account.amountAccount;
            newIncome.date = project.account.accountDate;
            newIncome.notes = project.account.accountType;
            incomes.push(newIncome);


        }



      });
      angular.forEach(projects, function(project){


        if (typeof(project.total.totalAmount) == 'number' && project.total.totalAmount > 0){
            var newIncome = {};
            newIncome.projectName = project.projectName;
            newIncome.clientName = project.clientName;
            newIncome.typeIncome = "Accompte";
            newIncome.amount = project.total.totalAmount;
            newIncome.date = project.total.totalDate;
            newIncome.notes = project.total.totalType;
            incomes.push(newIncome);


        }


      });

    });
    console.log(incomes); // still returns [];
    return incomes;

});

My problem is that the last log returns an empty array. I probably know why : incomes is returned before Projects.async().then(function(d) is executed.

But I don't know wait for this function to be executed before returning incomes in a service that call another service...

Any help ?

How do I get the phone owner's full name through AccountPicker?

Vote count:

0

I need both the phone owner's name and email.

I successfully obtained the name through using ContactsContract.Profile (how to get firstname and lastname of Android phone owner?), but I wasn't able to obtain an email. It is possible to get the email, but it isn't 100% that you'll get any data whatsoever (so even getting the name isn't 100%).

Hence, I'm using AccountPicker, AccountManager & the Google Play Services API to try to get it. That being said, I understand that this method doesn't guarantee getting the email or name either, but I'd at least like to know how to get the name. The following is how I got the email:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login_register);
    int REQUEST_EMAIL_CODE = 1;

    try {
        Intent intent = AccountPicker.newChooesAccountIntent(null, null,
                new String[] { "com.google" }, false, null, null, null, null);
        startActivityForResult(intent, REQUEST_EMAIL_CODE);
    } catch (ActivityNotFoundException e) {
      //handle error here
    } 
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1 && resultCode == RESULT_OK) {
        String userEmailAddress = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
   }
}

I'm not sure how I would obtain the name. I've tried replacing AccountManager.KEY_ACCOUNT_NAME with different things, but nothing yielded the result and usually I got an error. Maybe now that I have the email, there is a way to get the name from using it some key?

we have 4 entity , Bills, BillDetails ,Products, ProductGroups

var qry = from bill in ctx.Bills
          join billDetail in ctx.BillDetails on bill.Id equal billDetail.Bill_Id
          join product in ctx.Products on billDetail.Product_Id equals product.Id

          where 
               productGroup.Id == 113
          select bill;

the problem is if we disable lazy loading the returnded bill dos not contains BillDetail entity, we have to return it explicitly as anonymous object

is there any way to convert it to something like this ?

var qry = ctx.Bills
          .Include("BillDetails")
          .Include("BillDetails.Products")
          .Include("BillDetails.Products.ProductGroup")
