In this step we are going to add the ability to upload images into our app, and also sorting and naming them.
Angular-Meteor provides us with the [$meteor.collectionFS API](/api/files) that wraps [CollectionFS](https://github.com/CollectionFS/Meteor-CollectionFS).
[CollectionFS](https://github.com/CollectionFS/Meteor-CollectionFS) is a suite of Meteor packages that together provide a complete file management solution including uploading, downloading, storage, synchronization, manipulation, and copying.
It supports several storage adapters for saving to the local filesystem, GridFS, or S3, and additional storage adapters can be created.
So let's add image upload to our app! We will start by adding CollectionFS to our project by running the following command:
```
meteor add cfs:standard-packages
```
Now, we will decide the the storage adapter we want to use. CollectionFS provides adapters for many popular storage methods, link FileSystem, GridFS, Amazon S3 and DropBox.
In this example, we will use the GridFS as storage adapters, so we will add the adapter adapter by running this command:
```
meteor add cfs:gridfs
```
Note: you can find more information about Stores and Storage Adapters on the CollectionFS's GitHub repository.
So now we have the CollectionFS support and the storage adapter - we need to create a CollectionFS object to handle our files.
Note that you will need to define the collection as shared resource because you will need to use the collection in both client and server side.
### Creating the CollectionFS
I create the model/images.js file, and define a regular CollectionFS object called "Images", also, I used the CollectionFS API that allows me to defined auth-rules.
Finally, I publish the collection just like any other collection, in order to allow the client to subscribe to those images:
```
Images = new FS.Collection("images", {
stores: [
new FS.Store.GridFS("original")
],
filter: {
allow: {
contentTypes: ['image/*']
}
}
});
if (Meteor.isServer) {
Images.allow({
insert: function (userId) {
return (userId ? true : false);
},
remove: function (userId) {
return (userId ? true : false);
},
download: function () {
return true;
},
update: function (userId) {
return (userId ? true : false);
}
});
Meteor.publish('images', function() {
return Images.find({});
});
}
```
And let's add the usage of $meteorCollectionFS to our core controller (`PartiesListCtrl`):
```
$scope.images = $meteor.collectionFS(Images, false, Images).subscribe('images');
```
So now we have the collection, we need to create a client-side that handles the images upload.
### Image Upload
Note that you can use basic HTML `` or any other package as you want - you only need the HTML5 File object to be provided.
For our application, we would like to add ability to drag-and-drop images, so we can use AngularJS directives that handles file upload and gives us more abilities such as drag & drop, file validation on the client side and some more.
In this example, I will use [ng-file-upload](https://github.com/danialfarid/ng-file-upload), which have many features for file upload.
In order to do this, lets add the package to our project:
```
meteor add danialfarid:ng-file-upload
```
Now, lets add a dependency in the `app.js` file:
```
angular.module('socially',[
'angular-meteor',
/** ... more deps ... **/
'ngFileUpload'
]);
```
Now, before adding the actual file upload to the client, let's add a `$mdDialog` that will show the file upload form, in the `partiesList.js` file:
```
$scope.openAddImageModal = function() {
$mdDialog.show({
controller: 'AddPhotoCtrl',
templateUrl: 'client/parties/views/add-photo-modal.ng.html',
scope: $scope.$new()
}).then(function(image) {
// We will add here later the logic to handle the link between the image and the party
});
};
```
And add a button that calls our `openAddImageModal` function inside the create new party form:
```
Add Photo
```
As you can see, Now let's create the view for this dialog and add the `ng-file-upload` directive:
```
```
Also, in order to make the "drop-zone" look like a dropable area in my page, I added this CSS in the application stylesheet:
```
.drop-box {
background: #F8F8F8;
border: 5px dashed #DDD;
width: 230px;
height: 65px;
text-align: center;
padding-top: 25px;
margin-left: 10px;
}
.drop-box.dragover {
border: 5px dashed blue;
}
.drop-box.dragover-err {
border: 5px dashed red;
}
```
The main code in this HTML is the usage of `addImages` function in the `nfg-change` attribute, because this is the function that handles the main logic of uploading the image.
So let's create the controller (`addPhotoCtrl.js`) and implement this function:
```
angular.module("socially").controller("AddPhotoCtrl", ['$scope', '$meteor', '$rootScope', '$state', '$mdDialog',
function($scope, $meteor, $rootScope, $state, $mdDialog,) {
$scope.addImages = function (files) {
if (files.length > 0) {
$scope.images.save(files[0]);
}
};
$scope.close = $mdDialog.hide;
}]);
```
I also used ngfChange attribute to know when the user chooses a file, the callback is addImages($files), so lets add this to our `example.js` file instead of using "change" event:
```
$scope.addImages = function (files) {
$scope.images.save(files);
};
```
And that's it! now we can upload images by using drag and drop!
Now let's add some more cool features!
### Image Crop
One of the most common actions we want to make with pictures is edit it before saving, we will add to our example ability to crop images before uploading them to the server.
In this example, we will use [ngImgCrop](https://github.com/alexk111/ngImgCrop/) which provides us the ability to do that.
So lets start by adding the package to our project:
```
meteor add alexk111:ng-img-crop
```
And add a dependency in our module:
```
angular.module('socially', ['angular-meteor', /*...*/, 'ngImgCrop']);
```
We want to perform the crop in the client side only, before saving it in the CollectionFS, so lets get the uploaded image, and instead of saving it in the server - we will get the Data Url of it, and use it in the ngImgCrop:
```
$scope.addImages = function (files) {
if (files.length > 0) {
var reader = new FileReader();
reader.onload = function (e) {
$scope.$apply(function() {
$scope.imgSrc = e.target.result;
$scope.myCroppedImage = '';
});
};
reader.readAsDataURL(files[0]);
}
else {
$scope.imgSrc = undefined;
}
};
```
We take the file object and used HTML5 FileReader API to read the file from the user on the client side, without uploading it to the server.
Then we saved the DataURI of the image into a $scope variable.
Next, we will need to use this DataURI with the ngImgCrop directive as follow:
```
```
And let's change the logic of the "Done" button to call a function that will actually save the edited image:
```
Add Image
```
In order to save, we need to implement `saveCroppedImage()` function. We will use the same `$meteorCollectionFS` API we used before, just use the `save` function.
CollectionFS have the ability to receive DataURI and save it, just like a File object. So the implementation looks like that:
```
$scope.saveCroppedImage = function() {
if ($scope.myCroppedImage !== '') {
$scope.images.save($scope.myCroppedImage).then(function() {
$scope.uploadedImage = result[0]._id;
$scope.answer(true);
});
}
};
```
We will save the image call the `answer` function that just close the modal:
```
$scope.answer = function(saveImage) {
if (saveImage) {
$mdDialog.hide($scope.uploadedImage);
}
else {
if ($scope.uploadedImage) {
$scope.images.remove($scope.uploadedImage._id);
}
$mdDialog.hide();
}
}
```
And because we can share the information from the recently closed dialog with the main view (the add party form), we can just the Promise of the `show` function and implement a logic that will save the list of images we want to attach to out party:
```
$mdDialog.show({
controller: 'AddPhotoCtrl',
templateUrl: 'client/parties/views/add-photo-modal.ng.html',
scope: $scope.$new(),
}).then(function(image) {
if (image) {
if (!$scope.newPartyImages) {
$scope.newPartyImages = [];
}
$scope.newPartyImages.push(image);
}
})
```
And we are done! Now we have the ability to crop images and then save them using CollectionFS.
### Display Uploaded Images
Let's add a simple gallery to list the images in the new party form:
```
Add photo by clicking "Add Photo"
```
Cool! We can the all the images we want to attach to the new party!
Now let's add description to our images!
### Images Metadata & Description
Using CollectionFS, we can also save metadata on the files we store.
In order to to that, we just need to update the image object with the value, on the `metadata` property of each image.
In order to do that really nice and user-friendly, I used [angular-xeditable](https://github.com/vitalets/angular-xeditable).
Lets add the angular-xeditable package to our project:
```
meteor add vitalets:angular-xeditable
```
And add a dependency in our module:
```
angular.module('socially', ['angular-meteor', /* ... */ 'xeditable']);
```
Now, let's use angular-xeditable and add usage under the image:
```
{ { image.metadata.description || 'Click to add description' } }
```
And, of course, implement `updateDescription` function on the scope:
```
$scope.updateDescription = function($data, image) {
image.update({$set: {'metadata.description': $data}});
};
```
That's it! Now we have a photo gallery with description for each image!
### Sort Images
After we learned how to use CollectionFS metadata and how to update metadata values, we can also add an ability to sort and update the images order.
To get the ability to sort the images, let's use [angular-sortable-view](https://github.com/kamilkp/angular-sortable-view).
Add the package by running this command:
```
meteor add netanelgilad:angular-sortable-view
```
And then add a dependency for the module:
```
angular.module('socially', ['angular-meteor', /* ... */ 'angular-sortable-view']);
```
The basics of angular-sortable-view is to add the `sv-?` attributes to our page, just like the examples in the `angular-sortable-view` repository, So let's do that:
```
Add photo by clicking "Add Photo"
```
I use the `sv-on-sort` callback to know when the sort is done and which image moved to which position, the $partTo is the array with indexes updated after the sort is done.
Now let's implement the $scope function that will just save the order on the image as a local information, we will use it really soon.
```
$scope.updateOrder = function(sortedArr) {
angular.forEach(sortedArr, function(item, index) {
item.currentOrder = index;
});
};
};
```
We can also add a highlight to the first image, which we will use as the main image, by adding an indication for that:
```
// HTML
Main Image
// CSS
.main-image {
position: absolute;
top: 5px;
left: 5px;
background-color: #f8f8f8;
}
```
So now we have image gallery with ability to edit and add images, add a description to the images, and ability to sort.
Now we just need to add the logic that connect those images with that party we are creating!
### Link Image To Object
So as you know, we have all the images stored in `newPartyImages` array, we let's implement the `createParty` function, and save a link to the image with it's order:
```
$scope.createParty = function() {
$scope.newParty.owner = $rootScope.currentUser._id;
// Link the images and the order to the new party
if ($scope.newPartyImages && $scope.newPartyImages.length > 0) {
$scope.newParty.images = [];
angular.forEach($scope.newPartyImages, function(image) {
$scope.newParty.images.push({id: image._id, order: image.currentOrder})
});
}
// Save the party
$scope.parties.push($scope.newParty);
// Reset the form
$scope.newPartyImages = [];
$scope.newParty = {};
};
```
And that's it!
### Thumbnails
Another common usage with images upload, is the ability to save thumbnails of the image as soon as we upload it.
CollectionFS gives the ability to handle multiple Stores object, and perform manipulations before we save it in each store.
You can find the full information about image manipulation in the [CollectionFS docs](https://github.com/CollectionFS/Meteor-CollectionFS#image-manipulation).
Also, make sure you add `meteor add cfs:graphicsmagick` and install graphicsmagick, for more information, follow the instructions on the CollectionFS GitHub page.
So in order to add ability to save thumbnails, lets add a new store in the `model.js` and use `transformWrite` ability:
```
Images = new FS.Collection("images", {
stores: [
new FS.Store.GridFS("original"),
new FS.Store.GridFS("thumbnail", {
transformWrite: function(fileObj, readStream, writeStream) {
gm(readStream, fileObj.name()).resize('32', '32', '!').stream().pipe(writeStream);
}
})
],
filter: {
allow: {
contentTypes: ['image/*']
}
}
});
```
So now each image we upload will be saved also as thumbnail.
All we have to do is use and display the thumbnail instead of the original image. We just need to add a param to `url()` method of File objects and decide which Store to use when creating the URL:
```
```
That's it! Now we added the ability to save thumbnails for the images and use them in the view!
In addition to the angular-meteor-socially tutorial, you can find simple examples of each step of the tutorial in the Angular-Meteor repository, under examples/ directory.

Bee has pre-defined root Object with standard methods and attributes. The Object can be extended and can have a custom design constructor. You can create instances of Object and, you can use dot notation to access object members.
Method Call
An object can be instantiated using reserved keyword "new" and JSON literal or constructor Object() with arguments. After the object is created you can enhance the object.
** empty object
new object := {};
** set attribute values
new object.a1 := 1;
new object.a2 := 2;
** check the object
expect object = {a1:1, a2:2};
** remove attributes
del object["a1"];
del object["a2"];
** check the object
expect object = {};
Type of objects can be defined using JSON. You can enumerate attributes with type declarations in a complex structure. Later you can create instances of this type using the default object constructor.
** object subtype with attributes
type TName: {a1, a2 ∈ Type, a3 ∈ Type, ...} < O;
** call default constructor
new myObject = TName(a1:value1, a2:value2, a3 value3 ...);
Note: Default object constructor is created automaticly by the compiler. You can use the type-name as if you have already implemented a constructor for this new type.
Next example demonstrate an object with two attributes that have default values. Attributes with default values can be created using type inference.
** define object type using JSON
type T:{a1:10, a2:5};
** create two new objects
new obj1 := T(a2:0); -- a1, a2 are optional
new obj2 := T(1,10); -- attribute names are optional
** check the object
expect obj1 = {a1:10, a2:0};
expect obj2 = {a1:1, a2:10};
A custom object type can be created automaticly by the compiler using type inference. All you need is a rule that return an object with rule name reused as type. The compiler will detect that result type is not defined so it will create a default type behind the scene.
** define object constuctor
rule TName(a1 ∈ Type, ...) => (self ∈ TName):
** initialize object attributes
let self.a1 := a1;
....
** define object method
rule .name(self ∈ TName):
...
return;
return;
An object constructor is a high order rule. It has a static context and can contain object states and methods. All methods are sharing the same context. Result is by convention called "self" and it represent the current context.
Access to public members is enable by using dot qualifier notation. The qualifier is the actual object represented as input-output parameter or result: "self" that is explicitly defined as parameter for every public method.
Object scope is dynamic in contrast to the constructor scope that is static. The "self" scope is pass to public methods as a pointer. Object scope is created by the object constructor rule using keyword "new:.
We define an object constructor Foo that has two attributes and a public method. The constructor receive parameters (a,b) and create an object with attributes {a,b}. The .log() method is called using "apply" keyword.
** define object constructor:
rule Foo(a, b ∈ N) => (self ∈ Foo):
** create object attributes
new self.a := a;
new self.b := b;
** define method: log
rule .log(self ∈ Foo):
print "a =" + self.a;
print "b =" + self.b;
return;
return;
** test Foo
rule main:
** create an instance of Foo
new test := Foo(1,2);
** call a method test.log
apply test.log;
** verify attribute values
fail if test.a ≠ 1;
fail if test.b ≠ 2;
** what is the object type
print type(test); -- Foo
return;
a = 1 b = 2 Foo
Next example define an object using a constructor. This particular constructor can receive a variable number of arguments and produce an object that has two attributes.
** define the object type
rule MyObject(*v ∈ [N]) =>
(self: {sum ∈ N, avg ∈ R}):
** private variable
new count := 0;
cycle:
new x ∈ N;
for ∀ x ∈ v do
let self.sum += x;
let count += 1;
repeat;
let self.avg := self.sum / count;
return;
Note: In previous example we demonstrate type inference for result object. Object attributes are defined in the result declaration: Compiler will create the attributes from JSON and assign default values.
Bee objects are based on dictionaries. In fact an object do not have attributes it has keys. That is, each attribute is a (key:value) pair.
** define object type
rule MyObject(*values ∈ R) => (self ∈ O):
** set initial attributes
let self:={a1, a2, ... ∈ N};
** set attribute values in a loop
cycle:
new i := 0;
new k ∈ S;
for ∀ k ∈ self.keys() do
let self[k] := values[i];
let i += 1;
done;
return;
By default, Bee custom types are dynamic and can be extended using inheritance. We use symbol "<:" to define the super-type. A derived type can call super type constructor using qualifier: "super."
** define custom type
type Foo: {a, b ∈ N} <: Object;
** define Foo constructor
rule Foo(p1, p2 ∈ N) => (self &isin Foo);
let self := {a:p1, b:p2};
** overvrite the original method
rule .log():
print "a = ", self.a;
print "b = ", self.b;
return;
return;
** define Bar derived type:
type Bar: {a, b ∈ N, c ∈ R} <: Foo;
** define Bar constructor
rule Bar(p1, p2 ∈ N) => (self ∈ Bar);
let self := super(p1, p2);
new self.c := p1+p2;
** overvrite the original method
rule .log():
super.log();
print "c = ", slef.c;
return;
return;
** test Bar constructor
rule main:
new bar := Bar(3,4);
apply bar.log();
return;
a = 3 b = 4 c = 7
Bee can define an abstract constructor. This can contain forward declarations. These are method signatures that have no statements and can't be run.
Next example demonstrate how to create a constructor for abstract type. An abstract rule can't be instantiated directly. It is design for inheritance. You must implement all the abstract methods when you extend it.
** define abstract type
rule Root() => (self ∈ Root):
** define an abstract method
rule .log(self ∈ Root);
return;
** implement an abstract type
rule Foo(a,b ∈ N) =>(self ∈ Foo <: Root);
** imlement the log method
rule .log(self ∈ Foo):
for x ∈ self.keys() do
print x + " = " + self[x];
done;
return;
return;
rule main:
new foo := Foo(1,2);
apply foo.log;
return;
A trait is a special rule that encapsulate behaviour. Traits can be used to extend a specific type. When you apply a rule to an object this is enhanced with new behaviour.
An object, can be augmented using traits. The trits are specified using symbol + follow by a comma separated list of traits. The traits can be local or imported from other module.
type TName {attribute Type, ...} <: Object+(trait_list):
In next example we define a trait. The trait is used to define type Foo that is augmented. To signal an augmented object type you must use symbol "+" after the type name.
** define new trait
rule augment(self ∈ O):
** overvrite the log method
rule .log(self ∈ O):
for x ∈ self.keys() do
print x + " = " + self[x];
done;
return;
return;
** use trait augment to define Foo
rule Foo(a, b ∈ N) => (self:Foo <: Foo+):
** apply the augmentation
apply augment(self);
return;
rule main:
new bar = Foo(a:1, b:2);
apply bar.log;
return;
a = 10 b = 20
In data science you need to organize structured data in memory. Memory is flat so you can use Objects to make a complex structure. For example you can store Object references into a Collection.
type Person: {name ∈ S, age ∈ N} <: Object;
rule main:
** array of 10 persons
new catalog ∈ [Person](10);
** initialize value using literals
new catalog[1] := {name:"Cleopatra", age:15};
new catalog[2] := {name:"Martin", age:17};
** using one element with dot operators
print catalog[1].name; -- will print Cleopatra
print catalog[2].name; -- will print Martin
** member type can be check using _type()_ built in
print type(Person.name); -- will print U
print type(Person.age); -- will print W
** print size of structure
print size(Person);
return;
Recursive structure type is an Object that contains one or more references to other Objects of the same type as himself. The Object can grow in size and create a tree.
** example of single recursive node
type Node: {
data ∈ Z, -- integer data
previous ∈ Node -- reference to previous node
} <: Object;
A linked List could be created using this kind of Object. In principle a Linked List has 2 references. One is for prior element and another is the next element:
** example of double recursive node
type Node: {
data ∈ Z, -- integer data
prior ∈ Node, -- reference to previous node
next ∈ Node -- reference to next node
} <: Object;
Note: First element will have prior = Null. Last element will have next = Null. There is more to say about these kind of objects. We will explain complex data structures in the next chapter.

SAA Task Team To Begin Search For Salary Increase Difference In Two Weeks
by SW EditorA task team appointed to find money for salaries at South African Airways (SAA) said on Friday it would start its work in two weeks’ time.
The team will now need to find 2.1% for salaries after unions agreed on a 5.9% pay increase retrospective to April this year.
National Union Mineworkers of South Africa (Numsa) and the South African Cabin Crew Association (Sacca) had demanded an 8% increase, but have now called off their strike.
Talks on retrenchments have been deferred to next year. And for now, staff will be returning to work this weekend.
With regards to salary increases, Numsa and the Sacca have agreed that the remaining 2.1% that workers are demanding will be sourced by the appointed task team.
Numsa’s Phakamile Hlubi-Majola said: “We will work to ensure that we find the money because we believe that if you guys do what you are supposed to do by dealing with the corruption in the procurement spend, that money can be found. That’s why we established the task team.”
The Sacca’s Zazi Ntsibanyoni-Mngambi said the task team would not only consist of union representatives.
“It’s going to be ourselves as unions and SAA management because they are the ones with the contracts, and of course, the CCMA will facilitate and the DP and Treasury will play an oversight role.”
Flights are set to return to normal this weekend.
Meanwhile, unions say they have been able to negotiate for talks on retrenchments at SAA to be deferred to next year.
Numsa’s Hlubi-Majola says retrenchments have been delayed but only for members of her union and Sacca.
“Remember comrades we were supposed to start last week, and we said to them ‘you are out of your minds. There’s been no consultation, you haven’t done the right work’; so in other words, the bargaining forum where [National Transport Movement] NTM is dominant, sorry.”

Iconic Harajuku Station, located in Tokyo's hub of pop culture, to be rebuilt after Olympics
The nearly 100-year-old Harajuku Station, sited in a hub of Tokyo pop culture, will be dismantled and rebuilt after the Tokyo Olympic and Paralympic Games, as its fire-resistance capability does not meet requirements, East Japan Railway Co. said Tuesday.
The Western-style wooden station building, completed in 1924, is a gateway to the Harajuku district — a center of youth culture and street fashion. JR East said the new station will replicate as much as possible the current design, which features half-timbered structures that expose the building’s framework.
The area sees daily crowds of overseas tourists visiting Takeshita Street, a shopping lane lined with clothing stores and cafes, among other shops.
Aside from rebuilding the current station building, JR East also began constructing a new building in September 2016 located south of the current station that is set to open on March 21 next year, taking over station functions.
The train operator had been discussing whether to preserve or dismantle the present station building together with Shibuya Ward, where the station is located, and other parties.

The aim of this article is to carefully examine dating app culture, and debate whether this new culture is conducive or destructive to finding true love.
If you've spent some time around the block, you'll be familiar with Tinder's notoriousness as "the Sex App."
Unlike OkCupid, and JDate, Tinder doesn't ask the user for any personal information.
The decision of whether or not to pursue a prospect is solely based on looks.
Not that there's anything wrong with that! Within the first year of a long-term relationship, physical appearance will probably make up 80% of your reason for staying in the relationship.
There's nothing wrong with making decisions based on physical appearance. The true dangers is when any chance of real intimacy is sacrificed on the alter of meaningless sexual encounters.
Tinder is an epidemic for the future of love. Here are 3 reasons why I think that is:
The Height of Promiscuity: Then and Now
"We all want freedom, but we also have a basic human need for intimacy and meaning."
If you're familiar with the love culture from 70 years ago, then you'll realize just how far we've "evolved" from the norms of way back then.
In the 1940's, it was not abnormal for people to decide to get hitched after 3 weeks of knowing each other. So many people died in WWII, that people simply felt the realities of mortality much more intensely then we do today. Not only that, back then "promiscuity" wasn't as commonplace as it is today.
Case in point: In 1954, Marilyn Monroe stood on top of a subway grate in NYC, and the resulting photo was considered "the height of promiscuity." I'd compare this with a modern photo of a Miley Cyrus or Beyoncé outfit, but what's the point?
 Men are also made to feel that having 10 women on a string is a sign of masculinity. It's sad. Especially because only 0.1% of men can actually maintain the juggling act. Of course, about 30% of men just pretend like they're juggling 20 leads a time.
The Pros and Cons of Unlimited Possibility
So, we live in a society which has been sexually liberated. That's supposed to be a good thing, right?!
Here's where it becomes problematic though: we have become debilitated from making commitments because of the ocean of possibilities currently available to us.
In 1993, IBM was on the verge of bankruptcy before Lou Gerstner, a new CEO stepped in and saved the business. He attributed IBM's problems to "a lack of focus." The empire was involved in a wide variety of businesses, and spreading itself thin, as a "Jack of all trades," and "Master of none."
So, too, with modern dating culture. When we date 2 or 3 people at a time, it becomes very difficult to say no to that possibility of endless variety, and endless choices.
Apps, and the internet have opened up the ability to connect instantaneously with a swipe across your mobile phone. That comes with advantages, but also comes with dangers. We are drowning in a sea of endless possibilities.
This is dangerous because it decreases our ability to take emotional risks. Any time we are thinking of delving deeper into an existing relationship, we instead choose to take another swim in the sea of endless possibilities.
If we were wise, we would take a lesson from Andy Samberg and his movie "Hot Rod." Andy is able to choose his targets confidently, and has the courage to take risks, both emotionally, and physically.
Establishing Trust in a Culture of Games
When a man and a woman decide to take a chance on love, they are essentially letting their guard down, and choosing not to be cynical about romance.
Since the beginning of time, there have been barriers to achieving this level of trust. Many women often fear that "the guy only wants her for her body," while men often fear "the girl only wants him for the money." This is of course an out-dated saying, and today these concerns are actually intertwined and reversed.
Nonetheless, the Tinder culture has re-enforced this gnawing concern amongst women that the guy is solely pursuing her for her looks.

SDMTS Part 2 Static Data Exploration
In this post, we will explore the contents of the data set, and see what we can do with it!
Important Links
This post also has a supplemental R notebook. All of the code and the details of the exploration can be found there in the Part_2 folder. In this post I will only summarize the findings and display some highlights.
Introduction
The purpose of this post for me was to confirm my beliefs on what I thought the data values represented. For you, hopefully it will give you a better idea of how the data is mapped out through out this file system. Admittedly, my first exploration of this data set occurred before I knew anything about any RDBMS’s, and as a result was pretty painful. Hopefully with my summaries and the commands to put everything into postgresql makes everything crystal clear.
Mapping out a single trip
To start out, we’ll begin by mapping out a single trip. All of the code and details can be found in the R notebook. The 30 route has a special place in my heart, allowing me to surf every morning at 6 before class. Let’s begin by looking at a trip along this route!
The data we are going to need to plot this out are a trip_id, a list of stop_id’s and their coordinates, and a list of shape_pt’s and their coordinates. All of the data we need can be found in the shapes, stops, stop_times, and trips files. After a bit of munging and using the ggmap api we have the following map:
The black line represents the path taken by the trip and the red dots are all of the stops along the way.
Places
In the places file is a list of primary locations that are currently services by SDMTS. Let us take a look at its distribution on a map:
The SDMTS system seems to extend out to cover a large region. However, there is clearly a primary area of service, so let us take a closer look at that:
Conclusion
Unfortunately, the amount of interesting things that can be accomplished with this data alone is pretty limited. However, the code in notebook should help you get a more solid idea of how that static data is conveyed and how to extract useful ideas out of it. Moreover, this data serves as a necessary context for making sense out of the live feed data. In Part 3, I will cover the process I am using to gather data from the real time feed.

Sam Ward: GB & England player still 'dreams' of Tokyo 2020 despite 'freak' eye injury
Great Britain and England hockey player Sam Ward says it remains his "dream" to make the Tokyo 2020 Olympic squad despite suffering a "freak" eye injury.
The 28-year-old was struck in the face by the ball during GB's play-off win over Malaysia on 3 November, sustaining a crushed retina and facial fractures.
Ward has lost some vision in his left eye but hopes to play in Tokyo.
"That is my dream," he said. "It's been in my sight the last couple of years. I hope to be back and going to that."
Ward has scored 72 goals in 126 appearances for Great Britain and England and represented GB at the Rio 2016 Olympics.
He scored twice against Malaysia as GB secured qualification for the 2020 Games, which begin on 24 July.
"In my head, I've got a strong chance of coming back," he told BBC Radio 5 Live Drive.
"You've got to work hard, train hard, do your rehab right. The biggest thing is putting yourself in the best position possible, so making sure you make the right decisions day in, day out."
Ward's parents were at the Malaysia game and spoke to their son before he went to hospital, where he underwent surgery to repair the fractures.
He now has peripheral vision in his left eye and a grey patch in the middle, which has improved since what he described as a "freak incident".
"I have been informed there is retinal damage and it will never return to its full state," Ward added. "To what degree [it will recover], at the moment we don't know.
"It's a tough pill to swallow but it depends how you look at things. I'm a fully-functioning man, I've got everything I need, I've got all the support around - medical staff, the lot. There's a lot worse things out there in life. As long as you keep perspective, I'll be fine."
Head protection 'practically tough'
Hockey players wear face masks when defending penalty corners but Ward was attacking when he inadvertently blocked a goalbound shot by a team-mate.
"I remember seeing the ball heading towards my head, everything just seemed to slow down," he said.
"The way I play, I get into some funny positions. It helps me score goals but for the first time ever it really caught me out.
"It was a freak incident. I've known of other incidents but never this severe. I'm just unlucky. I put myself in that place so I've got to take it on the chin.
"It's a tough one to say whether it [head protection] should be worn in more areas of the game. It's one of those things that needs weighing up in time. Practically, it's pretty tough."


How to read DEXRDO prints:
jl777cLast Wednesday at 8:02 PM
this print has 3 parts
DEXpurge.145 for t.xxx -> n.0
that means for timeslot 145 at the unixtimestamp, it purged 0 packets
this makes sense as you need to run 59 minutes before anything will be purged.the rightmost part of L.8 A.1 coll.0 is the performance stats of the internal hashtable for recent requests. L is the number of lookups, A.1 is the number of additions to the hashtable and coll is the number of collisions
each collision will likely create a bit of redundant data transmission, that is why this is being tracked. my results show about a 0.1% collision rate, which is small enough to not matter as the goal is less than 20% redundant packets
now the middle part is what has the most important data
total.1 is the total number of packets that are in the RAM (sum of all timeslots)
the e59... is a combination of all the shorthashes (least 32 bits of actual hash XOR), given N packets, if it generates the same combination of shorthashes, odds are very good that the data is 100% in sync
R.1 S.0 A.1 duplicates.0
R.1 is the number of packets received
S.0 is the number of packets sent
A.1 is the number of packets added to the RAM. until purging starts, this should match the earlier total

text$ - Initial text for the menu
menu_id - User defined integer identifier parent - A menu handle |
|
CreateMenu creates a new menu and attaches it to the specified parent menu.
'Top level' window menus (for example, the 'File' and 'Edit' menus found in many applications, and the example below) should be attached to the menu returned by the WindowMenu command. Sub menu items are then attached to the menu handle returned by this command. The menu_id should uniquely identify what the menu item will do, as this id will be returned to you in EventData when the event occurs. Separator lines can be implemented by leaving the text$ blank. Shortcut keys can be implemented using the HotKeyEvent function. If you wish to show the keyboard shortcut in the menu, you should separate it from the main text using Chr$(8) or Chr$(9). This will ensure that it is correctly positioned in the menu. Chr$(8) results in right aligned shortcuts, whereas Chr$(9) results in left aligned shortcuts. See the example for details. ALT shortcut keys can be implemented by preceding the desired character in text$ with an ampersand (&). For example, if text$ is set to "&Copy", then the keyboard shortcut ALT-C will trigger the menu event. See also: WindowMenu, UpdateWindowMenu, SetMenuText, EnableMenu, DisableMenu, MenuDisabled, CheckMenu, UncheckMenu, MenuChecked. |

Jada Pinkett Smith in tears over 'complex' friendship with Tupac Shakur
The actress couldn't stop the tears from falling as she discussed her complex relationship with the late rapper on her Red Table Talk chat show
by Lucy Needham, https://www.facebook.com/dailymirror/Jada Pinkett Smith broke down in tears as she opened up about her friendship with Tupac Shakur, saying "It's hard to love someone who has a legacy."
The two stars both attended the same high school in Baltimore and went on to have a complex relationship and fell out just before the rapper was fatally shot in September 1996.
Jada became very emotional as she recalled her 'complex' relationship with Tupac with Robyn Crawford on her chat show Red Table Talk.
The pair spoke about the struggle of loving someone in the spotlight following the release of Robyn's book A Song For You which details her love affair with Whitney Houston.
"When you said [the book is] a love letter to Whitney, that resonated as so powerful," Jada told her guest. "It was so healing for me in so many different ways. It's hard to live someone who has had a legacy at the level she has had and then to lose them under tragic circumstances. I have a very similar situation."
Jada went on to say that she and Tupac acted as each other's 'anchors' when they found fame.
"Him feeling like, ‘You’re the only stability I got, I can’t afford for you to put that attention elsewhere,’" Jada said of Tupac.
"For him, it was, we were an anchor for each other. Anytime he felt like that anchor was threatened, oh my God,'" she added.
The actress previously revealed that she had bickered with Tupac before his death over her fears he was heading down a destructive path.
They were still not speaking when Tupac was killed in Las Vegas in 1996 meaning Jada never got to make ammends.
For her latest episode of Red Table Talk, Jada sat down with Robyn Crawford who discussed her relationship with Whitney Houston.
Robyn revealed that she had known Whitney for twenty years before she decided to walk away after becoming worried about her explosive marriage to Bobbi Brown.
"The more I saw and heard and the messier it got, I thought she'd get tired of it," Robyn recalled. "Whitney had a lot of pride and a strong will. But every time I thought that would be it, it wasn't."
Blinking back tears, Jada said: "I know the depth of that struggle, having to do it as well."
Speaking to Howard Stern in 2015, Jada described how she and Tupac got into a "hardcore" fight before he died.
"There’s not a day that goes by that I don’t think about Pac. I think about him every single day," she said of her high school friend.
She said that she and Tupac lacked 'physical chemistry' and did kiss each other once but it never went anywhere.

Sets the inhibition radius based off the average receptive field size. The average receptive field size is the distance of the connected synapses with respect to to their input column. In other words, it is the distance between a column and its input source averaged across all connected synapses. The distance used is the Euclidean distance. Refer to the initialization of self.syn_dist for more details. NOTE

Signals
Methods
Detailed Description
Add items to the ComboBox by assigning it a ListModel, or a list of strings to the model property.
ComboBox { width: 200 model: [ "Banana", "Apple", "Coconut" ] }
In this example we are demonstrating how to use a ListModel with a combo box.
ComboBox { currentIndex: 2 model: ListModel { id: cbItems ListElement { text: "Banana"; color: "Yellow" } ListElement { text: "Apple"; color: "Green" } ListElement { text: "Coconut"; color: "Brown" } } width: 200 onCurrentIndexChanged: console.debug(cbItems.get(currentIndex).text + ", " + cbItems.get(currentIndex).color) }
You can make a combo box editable by setting the editable property. An editable combo box will autocomplete its text based on what is available in the model.
In the next example we demonstrate how you can append content to an editable combo box by reacting to the accepted signal. Note that you have to explicitly prevent duplicates.
ComboBox { editable: true model: ListModel { id: model ListElement { text: "Banana"; color: "Yellow" } ListElement { text: "Apple"; color: "Green" } ListElement { text: "Coconut"; color: "Brown" } } onAccepted: { if (find(currentText) === -1) { model.append({text: editText}) currentIndex = find(editText) } } }
You can create a custom appearance for a ComboBox by assigning a ComboBoxStyle.
Property Documentation
Returns true
if the combo box contains acceptable text in the editable text field.
If a validator was set, this property will return true
if the current text satisfies the validator or mask as a final string (not as an intermediate string).
This QML property was introduced in QtQuick.Controls 1.1.
This property specifies whether the combobox should gain active focus when pressed. The default value is false
.
This property holds the number of items in the combo box.
This QML property was introduced in QtQuick.Controls 1.1.
The text of the currently selected item in the ComboBox.
Note: Since currentText
depends on currentIndex
, there's no way to ensure currentText
will be up to date whenever a onCurrentIndexChanged
handler is called.
This property specifies text being manipulated by the user for an editable combo box.
This QML property was introduced in QtQuick.Controls 1.1.
This property holds whether the combo box can be edited by the user. The default value is false
.
This QML property was introduced in QtQuick.Controls 1.1.
This property holds whether an editable ComboBox has partial text input from an input method.
While it is composing an input method may rely on mouse or key events from the ComboBox to edit or commit the partial text. This property can be used to determine when to disable events handlers that may interfere with the correct operation of an input method.
This QML property was introduced in QtQuick.Controls 1.3.
Provides hints to the input method about the expected content of the combo box and how it should operate.
The value is a bit-wise combination of flags or Qt.ImhNone
if no hints are set.
Flags that alter behavior are:
- Qt.ImhHiddenText - Characters should be hidden, as is typically used when entering passwords.
- Qt.ImhSensitiveData - Typed text should not be stored by the active input method in any persistent storage like predictive user dictionary.
- Qt.ImhNoAutoUppercase - The input method should not try to automatically switch to upper case when a sentence ends.
- Qt.ImhPreferNumbers - Numbers are preferred (but not required).
- Qt.ImhPreferUppercase - Upper case letters are preferred (but not required).
- Qt.ImhPreferLowercase - Lower case letters are preferred (but not required).
- Qt.ImhNoPredictiveText - Do not use predictive text (i.e. dictionary lookup) while typing.
- Qt.ImhDate - The text editor functions as a date field.
- Qt.ImhTime - The text editor functions as a time field.
Flags that restrict input (exclusive flags) are:
- Qt.ImhDigitsOnly - Only digits are allowed.
- Qt.ImhFormattedNumbersOnly - Only number input is allowed. This includes decimal point and minus sign.
- Qt.ImhUppercaseOnly - Only upper case letter input is allowed.
- Qt.ImhLowercaseOnly - Only lower case letter input is allowed.
- Qt.ImhDialableCharactersOnly - Only characters suitable for phone dialing are allowed.
- Qt.ImhEmailCharactersOnly - Only characters suitable for email addresses are allowed.
- Qt.ImhUrlCharactersOnly - Only characters suitable for URLs are allowed.
Masks:
- Qt.ImhExclusiveInputMask - This mask yields nonzero if any of the exclusive flags are used.
This QML property was introduced in QtQuick.Controls 1.5.
menu : Component |
model : model |
The model to populate the ComboBox from.
Changing the model after initialization will reset currentIndex to 0
.
This property determines if the user can select the text in the editable text field with the mouse.
The default value is true
.
This QML property was introduced in QtQuick.Controls 1.3.
style : Component |
The style Component for this control.
See also Qt Quick Controls Styles QML Types.
The model role used for populating the ComboBox.
Allows you to set a text validator for an editable ComboBox. When a validator is set, the text field will only accept input which leaves the text property in an intermediate state. The accepted signal will only be sent if the text is in an acceptable state when enter is pressed.
Currently supported validators are IntValidator, DoubleValidator, and RegExpValidator. An example of using validators is shown below, which allows input of integers between 11 and 31 into the text field:
Note: This property is only applied when editable is true
import QtQuick 2.2 import QtQuick.Controls 1.2 ComboBox { editable: true model: 10 validator: IntValidator {bottom: 0; top: 10;} focus: true }
This QML property was introduced in QtQuick.Controls 1.1.
See also acceptableInput, accepted, and editable.
Signal Documentation
This signal is emitted when the Return or Enter key is pressed on an editable combo box. If the confirmed string is not currently in the model, the currentIndex will be set to -1 and the currentText will be updated accordingly.
Note: If there is a validator set on the combobox, the signal will only be emitted if the input is in an acceptable state.
The corresponding handler is onAccepted
.
This QML signal was introduced in QtQuick.Controls 1.1.
This signal is similar to currentIndex changed, but will only be emitted if the combo box index was changed by the user, not when set programmatically.
index is the activated model index, or -1
if a new string is accepted.
The corresponding handler is onActivated
.
This QML signal was introduced in QtQuick.Controls 1.1.
Method Documentation
Finds and returns the index of a given text If no match is found, -1
is returned. The search is case sensitive.
This QML method was introduced in QtQuick.Controls 1.1.
Causes all editText to be selected.
This QML method was introduced in QtQuick.Controls 1.1.
Returns the text for a given index. If an invalid index is provided, null
is returned
This QML method was introduced in QtQuick.Controls 1.1.

[telegram] <n> Guys i read the whitepaper & stuff but i haven't really found an answer to my question..how is komodo price gonna rise if kmd is not used on the blockchain created with komodo tech?
can you believe that the larger the komodo ecosystem, the better for KMD?
if so, then each new coin in the komodo ecosystem, helps KMD, without paying any "KMD tax"
this idea that a coin only has value if it is taxing all the projects that use it, it seems to ignore the elasticity of demand based on price
if something is more expensive, less people will use it
if it is free, then the most people will use it
komodo is a tax free zone
it will become one of the largest ecosystems in crypto
KMD will be at the center of this
granted it is a long term thing and wont be apparent in a day, week, month or even year. but as the ecosystem gets to 1000+ projects, then the effect will indeed become a powerful one

[telegram] <Dwydco> @Thomas : not in first version, the goal was back then to have a secure solution for pirates. The app was released on beta in december and already worked well. I was sidetracked by investors research and financial issues, and wanted to have a solid company secured by lawyers to begin operate.
Back then MMv2 was still not finished, but it always has been my goal, I just prefered the layered approach building a system on a centralisef infra to get the logic and core going, to progressively migrate to other tech like MMv2.
The devtime estimated between the 2 being so different, I prefered the choice of a slow start with something reliable, and tend to go to DEX tech on next iterations.
[telegram] <Dwydco> the goal is double : migrate to decentralized solution while maintaining a good service, and switch progressively. But to be efficient I can t stay alone, and have to find people to make this happen faster, this needs funding so I have to start somewhere :)
[telegram] <Dwydco> I assume that building and refining will bring more knowledge and understanding to shape better ideas using the tech as it has to be used than forcing the use directly.
The problem with current dexes is GUI, so refining a good one and just replacing the backend with dex tech makes it possible to obtain experience in both UI and core and develop ton of featured instead of being blocked on technical subjects

Top 3 Cloud Providers across the globe
Amazon Web Services (AWS), a collection of remote computing services, also called web services, make up a cloud-computing platform offered by Amazon.com. These services operate from 11 geographical regions across the world. The most central and well-known of these services arguably include Amazon Elastic Compute Cloud and Amazon S3. Amazon markets these products as a service to provide large computing-capacity more quickly and more cheaply than a client company building an actual physical server farm.
Google Cloud Platform is a cloud computing platform by Google that offers hosting on the same supporting infrastructure that Google uses internally for end-user products like Google Search and YouTube. Cloud Platform provides developer products to build a range of programs from simple websites to complex applications.
Microsoft Azure is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed and Microsoft partner hosted datacenters. It provides both PaaS and IaaS services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems


Rules/Regulations:
Make a presentation (ppt) on any one of your favourite cars (even an ATV/
formula one) of any company. You have to act as a representative trying to sell
your product.
Presentation must contain the following points:
- Car Features (including photos)
- Cost
- Why people would buy your product?
- Any extra thing which you want to add.
Extra points if you include a small video (1 min max) on that car in the
presentation.
Maximum time for presentation: 6 minutes.
You can participate individually or in a team of two.
Judging criteria:
- Presentation Skills
- Content of the ppt
- Are you able to convince the costumer(judges in this case) to buy your
product
- How much good is your product
- How much knowledge you have about your product


--- layout: archive title: Zulip Chat Archive permalink: /stream/116395-maths/topic/unique.20ring.20hom.20from.20.E2.84.9A.html ---
Lean is asking me to prove f r = g r
where f
and g
are two ring homs, and r : ℚ
. Is this statement in mathlib?
There is eq_cast
, but this gives you a ton of goals instead of just is_ring_hom f
. Also, the cast only works for division rings :scream: (which is of course necessary, but doesn't help me)
It's not true for arbitrary ring homs, I think. You can freely define the "divide by p" operation in the ring unless you know the ring is a domain or is multiplicatively cancellative
But Mario, the image of 1/n
must be a multiplicative inverse of n
.
that element must satisfy n * a = 1
but why is there a unique such element?
unless you know n * a = n * a' => a = a'
Sure yeah, I just baulked at "freely" without thinking
I mean freely relative to that restriction of course
I mean, there are even two ring homs Q -> Q
, the identity and the zero map.
lol
Wait are mathlib ring homs identity-preserving
yes
Ok then scratch that
Inverses are unique
why?
without cancellation
Are we talking about commutative rings?
I guess so
Then inverses are unique
why?
If a*b=1
and a*c=1
then b*a*c=b=c
Just like there's a unique map from Z to any ring, there's at most one map from Q to any comm ring
I see, so commutativity is essential here
My gut feeling is that we don't need comm ring but I'm supposed to be marking 500 scripts not reading this
So let me humiliate myself by trying to figure this out in real time
Man I am so bad at rings.
by which I mean noncommutative rings
Obviously we need that a ring hom sends 1 to 1 (and I know people who don't even believe this)
Is it true for the ring of half-integers?
It's bound to be true
I'd know a weird example if it weren't true
So the question currently is that if Z[1/2] -> R is a ring hom between rings with 1 (R not necc commutative) which sends 1 to 1 then is it the only one?
yes
And my money is on yes
21/2=1/22=1
meh
2 x 1/2 and 1/2 x 2 are both 1 in Z[1/2]
so I bet the same argument works
If a and b are two candidates for the image of 1/2 then we can still run the same argument becuase we have associativity and one_mul and mul_one
a*(2*b)=(a*2)*b
and this works in general, so Johan doesn't even need commutative, as long as 1 is going to 1
(which implies 2 is going to 1+1)
(i.e. a unique place)
Students learn in maths departments that in lots of categories "surjective" is the same as "epimorphism" and "injective" is the same as "monomorphism"
yeah, that sounds right
and then we pull out the example of the category of rings, where Z -> Q is both monic and epic
so I think I was probably proving that.
whilst worrying about whether we should have been pulling out the category of commutative rings instead.
OK see you in 2 weeks
when I've finished this marking
[yeah right]
I guess the correct statement is that in a general not-necc-commutative ring, two-sided inverses are unique.  I really must go away.
@Kevin Buzzard GO AWAY!!!

The image of a ring hom from a commutative ring is a commutative ring.
this is the important bit, I think; the fact that f n
is always in the center of the ring
The image of a ring hom from a commutative ring is a commutative ring.
Yes but the problem with this argument is that the two images might be different commutative subrings.
this is the important bit, I think; the fact that
f n
is always in the center of the ring
Is that obvious? I don't see how we have access to facts about stuff not in the image.
It might well be true but I don't see it immediately.
and lunch is nearly over :-/
I have no feeling for how bad noncommutative rings can be.
Is there some crazy non-commutative polynomial ring Q[z] where lambda z isn't z lambda for lambda in Q?
Oops, I mean that f n
and f m
commute
there's a theorem about that in nat.cast
For commutative rings I have a really powerful feeling about how to build them -- throwing in generators and relations -- but for non-commutative rings I don't know what one can get away with.
I think non-commutative rings are as broken as semigroups -- not enough axioms!
this follows from the universal property of the fraction field and the uniqueness of maps from Z, right?
For commutative rings, sure.
@Mario Carneiro Do you want to PR you lemma? Or shall I do it? What would be a good file to put it in?

Client Side Basic Data Binding is now capable of updating dynamic data without having a manual refresh in the client side. But assume, what happen if these dynamic data is available in the server side and time to time that server emitting a new dynamic stream of data, can we bind these kind of data to the dropdown? In these type of situations, Server side data binding is introduced.
Server side data binding is handled via onDataBind callback function. It allow users to customize the data binding logic and will be triggers on dropdown initialization and on dynamic data dropdown operations. This function will receive DropdownRequestParams argument and expect to return RxJS Observable query result DropdownQueryResult<T> object stream. Data returned from this callback function will be directly bound to dropdown assuming that it matches the on demand request context.
For use of Server side web socket data binding operations it is mandatory to import DropdownResourceModule to your application module.
Let's see how it uses a simple socket connection to emit data in an time interval and how it could listened from the client side in step by step.
In the very first of component initialization, you can creates a web socket connection for browser environment. refer the below code snippet for Global Ref Service isBrowser method.
Then, if window is not undefined
, Dropdown Web Socket Data Fetch Service init
method will triggers with web socket endpoint. refer the below code snippet.
Then DropdownDataBindCallback
data can be bind into onDataBind
property.
After all socket connection will keep alive with a RxJS
Interval and it will emit a data set for Dropdown Web Socket Data Fetch Service socketStream
method with a object which contains keep-alive
tag in every defined interval.
After all done, OnDestroy Angular life cycle hook automatically triggers and invoke Dropdown Web Socket Data Fetch Service dispose method and unsubscribe all the subscriptions and complete the web socket connection operations.
The complete set of code snippet for the server side web socket data binding via onDataBind call back function can be seen in What You Will See section example.

Explanation
BlocJams stores album information and plays songs within the albums. Originaly created with vanilla javascript, refactored with jQuery, and then remade with AngularJS, the application stores albums and plays music based on user input. The application consist of a homepage, a collection page filled with stored albums, and the album page that displays the album itself along with each song the album contains. When a song is selected, a responsive player bar actively displays the current song.
Problem
This is a problem that caused me to come up with BlocJams. Essentially, this section is the client’s request taken and broken down into a list of problems. This is where we define our problems. A pseudocode of sorts.
Solution
In here, we take each problem listed above and discuss how we solved it, or if we solved it.
Results
BlocJams plays music.
This project was amazing. - AverageUserMonthly Magazine
OMG IT PLAYS MUSIC! - Captain Morthan Obvious
4 stars! - An astronomer counting Aries in the sky
Conclusion
BlocJams can play music, skip songs, replay them. Doubts I had stemmed from never coding before. I learned javascript and jQuery and the difference between the two.

Brute Force Browsing
Contents
Description
- Most Web browsers have a standard behavior of listening on port 80 for HTTP traffic and port 443 for HTTPS traffic.
- A Web server is only supposed to access files reachable from its own document root directory.
- Common Gateway Interface (CGI) is intended to allow ordinary programs to interact using a Web browser interface.
- CGI interfaces are present at the core of almost all Web applications
- The Web server can restrict access to a CGI to specific users but cannot limit the files that the CGI can access.
- These facts lead to a set of vulnerabilities called “forceful browsing” or 'brute-force browsing“ vulnerabilities.
- In these vulnerabilities, an attacker can manipulate values in the data they submit to a CGI program by way of the browser and thus force the Web server to return Web pages or other files that the attacker would be unable to access otherwise.
Types of Forceful Browsing
URL Guessing
- Guess the names of Web pages and enter them in the browser to see if they find a real page and if they can access it.
- Because the only security on these pages is that they are not linked to anywhere on the site that can be seen by a regular user.
Session Replay Attack
- This type takes place when the attacker knows the URL already. This can be done via saved URLs where the attacker had one instance of legitimate access to the URL and now replays the URL to regain access or replay a prior transaction. If this succeeds. the attacker has carried out a session replay attack.
- The root cause of this vulnerability is the lack of state HTTP and CGIs were never intended to he accessed in a stateful fashion.
- Sometimes. a session variable is used to associate an authenticated user with a particular session, but these session variables can't he immediately expired by the server because any lag in the communication will cut off the legitimate user from his session.
- Session variables are often stored in hidden fields in the HTML Pages of the site, or they are transmitted as art of the URL.
Non-URL Forceful Browsing
- URLs are the most common places from which to perform forceful browsing, but it is not the only place where browsing can be accomplished. Any of the CGI parameters that are present in the fields of the HTML page (both hidden and unhidden) can he tampered with.
Anatomy of an Exploit
URL Guessing
- An attacker visits a Web site
- for example: http://www.mywebsite.html/default.html.
- When the attacker browses the site. the attacker notices that there is a pattern to the URLs being seen.
- The link titled New Member” leads to the URL http://www.mywebsite.html/newmember.html.
- The link titled “Consultants” leads to the URL http://www.mywebsite.html/consultants.html.
- The attacker notices that there is no URL listed that seems to have anything to do with site administration and decides to see if he can find It.
- He guesses at a couple of URLs until he happens to guess the correct URL to achieve some level of access: http://www.mywebsite.html/admin.html.
Session Replay
- An attacker sits down at a coworker's desk after the coworker has stepped away, and the computer is left unlocked. The coworker had just shown the attacker the new item he bought at a major online retailer.
- The attacker navigates to the account management page and changes coworker‘s email address and password to his own, then logs out of the online retailer's site and closes the browser before returning to his own desk.
Real-World Examples
- Kerio Personal Firewall TM is a firewall for workstations. In 2003, a session replay vulnerability was reported. The vulnerability reported involved a law in the authentication when the firewall's remote administration was being used. The traffic during the session is encrypted. but if the entire administration session is captured using a network sniffer and then replayed as a whole, the server recognizes it as a valid session.
- The impact of this vulnerability is that an attacker could record a session and replay it at will to cause the same administrative commands to be sent to the firewall.
Test Techniques
URL Guessing
- Start testing for brute-force browsing vulnerabilities by mapping your site. Begin by creating a list of all the URLs that are intended to be safe and accessible to everyone, including those people who aren't logged in.
- Log on to your site as an administrator and manually walk through all the pages you can access or find links to.
- The next step is to log out of the site completely, and clear your browser cache and cookies. Go back to your site and try all of the URIs both from the safe list and the administrator list. Mark each of the URLs that is reachable.
- Now repeat this process while logged in as a normal user. Again, mark each of the accessible pages. If there is any page that is accessible by non admininistrators and it is not on the safe list, then you have a URI–guessing security vulnerability.
Session Replay
- Start by seeing if you can detect how your system is storing session information.
- Log into the system as a regular user, and navigate to a URL that requires you to be logged into the system to access. Look at the URL that is displayed in your browser's address bar. Does it contain any parameters with names like “session” or any long strings of seemingly random letters and numbers? If either of these are true, the URL probably contains the session variable.
- Now save the current page to a local file, and log out of your site. Delete your browser's cache and clear your cookies, then try opening the saved file in your browser, and click on one of the links. If you can still navigate around the site, your system may be vulnerable to a session replay attack.
- Try copying the URL to a file, and close your browser. Clear your cache and cookies again. Reopen your browser and paste the URL into the address bar and see if you can access the site without logging in. If you can, you may have a session replay attack.
- To verify your findings, try the same process from a different machine with the locally saved file and the URL. If you can still access the site without logging in, you have a confirmed vulnerability.
