      generally speaking, there can be a few independent but overlapping mechanism that will control who is allowed to do what with content: 1. any subject's access to the content itself can be controlled via authorization rules (ie. required vs granted permissions) enforced via system-wide resource-based access control 2. content licensors (~content owners) can restrict the usage of their content by: * whom - ie. content licensee (legally/commercially represented by an organization) * how - eg. reuse as unmodified, create derivatives, composite, redistribute, etc * where - ie. distribution channels their content can be used (eg. only on hotel's vbrochure site, but not in any ids/gds channels) * when - temporal restrictions may limit scope of content license grant by: start, end, duration, season, etc 3. content licensees can further filter or funnel content available to them (resulting from a combination of license granted to them and access control) based on their own criteria (eg. generate a templated hotel presentation only if: at least 1 textual description, 5 photos and 1 video for a hotel is available with a license to combine them (composite content)

      don't just use the attribute's type with first character lower cased!!! argghhh!  (eg. instead of Node node, Node parent)
  • Do Not Model Scaffolding Code
  • Include an Ellipsis ( … ) At The End of Incomplete Lists
  • Develop Consistent Method Signatures
  • Avoid Stereotypes Implied By Language Naming Conventions
  • 3.        Interfaces
  • Name Interfaces According To Language Naming Conventions
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      I+ is NOT an acceptable naming convention!  this is a very dumb, thoughtless, pointless convention originated by microsoft
    • kuni katsuya
      kuni katsuya on 19 Dec 12
  • Do Not Model the Operations and Attributes of an Interface in Your Classes
  • Consider an Interface to Be a Contract
  • 4.        Relationship Guidelines
  • Model Relationships Horizontally
  • Depict Similar Relationships Involving A Common Class As A Tree
  • Always Indicate the Multiplicity
  • reduce clutter in the diagram
  • Avoid a Multiplicity of “*”
  • Replace Relationships By Indicating Attribute Types
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      if dependency relationships were drawn between every class and the types of it's attributes, the class diagram becomes cluttered very quickly this dependency is obvious if the type is indicated for each attribute
  • Do Not Model Every Single Dependency
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      generalization of #7 what you show/don't show depends on the main concepts  you're trying to convey in any specific diagram
  • Write Concise Association Names In Active Voice
  • Indicate Directionality To Clarify An Association Name
  • Name Unidirectional Associations In The Same Direction
  • Indicate Role Names When Multiple Associations Between Two Classes Exist
  • Indicate Role Names on Recursive Associations
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      eg. parent, child
  • Make Associations Bi-Directional Only When Collaboration Occurs In Both Directions
  • Question Multiplicities Involving Minimums And Maximums
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      this just leads to stupid programming practices like hard-coding array sizes, making code more brittle
  • 6.        Inheritance Guidelines
  • “is a”
  • “is like” relationships
  • Apply the Sentence Rule For Inheritance
  • Place Subclasses Below Superclasses
  • A Subclass Should Inherit Everything
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      if a subclass sets an attribute to null, implements a method returning null or throwing a NotImplementedException, it really isn't a subclass, or the superclass needs to be decomposed
  • 7.        Aggregation and Composition Guidelines
  • object is made up of other objects
  • aggregation
  • “is part of” relationships
  • whole-part relationship between two objects
  • Composition
  • stronger form of aggregation where the whole and parts have
  • coincident lifetimes, and it is very common for the whole to manage the lifecycle of its parts
  • Apply the Sentence Rule for Aggregation
  • Depict the Whole to the Left of the Part
  • Don’t Worry About Getting the Diamonds Right
  • associations, aggregation, composition, dependencies, inheritance, and realizations
  • line on a UML class diagram
  • defines a cohesive set of behaviors
  • Indicate Visibility Only On Design Models
  • Design Class Diagrams Should Reflect Language Naming Conventions

  • interfaces define

    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      this is one sensible interface naming option, if the interface encapsulates a cohesive set of behaviors and yes, compared to blindly following the meaningless I+ convention, it requires some thought, but thinking of an appropriate name also forces you to (re)consider the interface's primary responsibility and how it fits into the overall design imho, a class diagram for a domain model should be almost fluently readable english
  • not types
  • ...16 more annotations...
  • Comparable
  • Runnable
  • Serializable
  • Sometimes an Adjective doesn't make sense, but I'd still generally be using interfaces to model behavior, actions, capabilities, properties, etc,... not types.
  • Also, If you were really only going to make one User and call it User then what's the point of also having an IUser interface?
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      another anti-pattern... blindly create an interface for every class, even if there's only one implementation!! arrgghhhh! consider introducing an interface when there are 2-3 well-distinguished, concrete implementations required
  • if you are going to have a few different types of users that need to implement a common interface, what does appending an "I" to the interface save you in choosing names of the implementations?
  • prefer not to use a prefix on interfaces:
  • hurts readability.
  • interfaces names should be as short and pleasant as possible
  • Implementing classes should be uglier to discourage their use.
    • kuni katsuya
      kuni katsuya on 19 Dec 12
       
      but they don't *have* to be ugly, like BlahImpl for specialized implementations, use descriptive adjective-noun combos
  • Code using an instance of some type should never, ever care if that type is an interface or a class
  • exposing such a detail in the name of the type is pointless and harmful to understanding
  • several reasons Java does not generally use the IUser convention.
  • should not have to know whether the client is using an interface or an implementation class
  • Java naming convention prefers longer names with actual meanings to Hungarian-style prefixes
  • Interface naming in Java [closed]

  • Session Management Cheat Sheet
  • should not be extremely descriptive nor offer unnecessary details
  • change the default session ID name of the web development framework to a generic name
  • ...50 more annotations...
  • length must be at least 128 bits (16 bytes)
  • Session ID Length
  • Session ID Name Fingerprinting
  • Session ID Properties
  • Session ID Entropy
  • must be unpredictable (random enough) to prevent guessing attacks
  • good PRNG (Pseudo Random Number Generator) must be used
  • must provide at least 64 bits of entropy
  • Session ID Content (or Value)
  • content (or value) must be meaningless
  • identifier on the client side
  • meaning and business or application logic associated to the session ID must be stored on the server side
  • session objects or in a session management database or repository
  • create cryptographically strong session IDs through the usage of cryptographic hash functions such as SHA1 (160 bits).
  • Session Management Implementation
  • defines the exchange mechanism that will be used between the user and the web application to share and continuously exchange the session ID
  • token expiration date and time
  • This is one of the reasons why cookies (RFCs 2109 & 2965 & 6265 [1]) are one of the most extensively used session ID exchange mechanisms, offering advanced capabilities not available in other methods
  • Transport Layer Security
  • use an encrypted HTTPS (SSL/TLS) connection for the entire web session
  • not only for the authentication
  • process where the user credentials are exchanged.
  • “Secure” cookie attribute
  • must be used to ensure the session ID is only exchanged through an encrypted channel
  • never switch a given session from HTTP to HTTPS, or viceversa
  • should not mix encrypted and unencrypted contents (HTML pages, images, CSS, Javascript files, etc) on the same host (or even domain - see the “domain” cookie attribute)
  • should not offer public unencrypted contents and private encrypted contents from the same host
  • www.example.com over HTTP (unencrypted) for the public contents
  • secure.example.com over HTTPS (encrypted) for the private and sensitive contents (where sessions exist)
  • only has port TCP/80 open
  • only has port TCP/443 open
  • “HTTP Strict Transport Security (HSTS)” (previously called STS) to enforce HTTPS connections.
  • Secure Attribute
  • instructs web browsers to only send the cookie through an encrypted HTTPS (SSL/TLS) connection
  • HttpOnly Attribute
  • instructs web browsers not to allow scripts (e.g. JavaScript or VBscript) an ability to access the cookies via the DOM document.cookie object
  • Domain and Path Attributes
  • instructs web browsers to only send the cookie to the specified domain and all subdomains
  • “Domain” cookie attribute
  • “Path” cookie attribute
  • instructs web browsers to only send the cookie to the specified directory or subdirectories (or paths or resources) within the web application
  • vulnerabilities in www.example.com might allow an attacker to get access to the session IDs from secure.example.com
  • Expire and Max-Age Attributes
  • “Max-Age”
  • “Expires” attributes
  • it will be considered a
  • persistent cookie
  • and will be stored on disk by the web browser based until the expiration time
  • use non-persistent cookies for session management purposes, so that the session ID does not remain on the web client cache for long periods of time, from where an attacker can obtain it.

  • most common solution is to
  • have a second persisted id, the uid

  • recommended approach to avoid any kind of subtle problems is to have a real uid property which will be persisted in the database but is not a primary key for efficiency concerns

  • EntityGraphUnintializer
  • uninitializeEntityGraph
  • Person object will be uninitialized
  • uperson contains
  • only the minimum of data
  • to correctly merge your changes in the server persistence context
  • Tide uses the
  • client data tracking
  • to determine which parts of the graph need to be sent
  • Calling the EntityGraphUninitializer manually is a bit tedious and ugly, so there is a cleaner possibility when you are using generated typesafe service proxies
  • annotate your service method arguments with @org.granite.tide.data.Lazy :
  • @Lazy
  • take care that you have added the [Lazy] annotation to your Flex metadata compilation configuration
  • in the Flex application, register the UninitializeArgumentPreprocessor component in Tide as follows :
