அறிவியற்பா: பொருண்மையீர்ப்பு அலைகள்!

பொருண்மையீர்ப்பு அலைகளில் முக்கியப் பங்காற்றியுள்ள இந்திய

Tata Institute for Fundamental Research, Chennai Mathematical Insitute, Indian Institute of Sci. Ed. and Research – Trivandrum and Kolkata, Inter-University Campus for Astronomy and Astrophysics, IIT Gandhinagar, Raja Ramanna Center for Advanced Tech.-Indore -ஆய்வாளர்களுக்கு வாழ்த்துகள்!

நேற்று வெளிவந்த பொருண்மையீர்ப்பு அலைகளைப் பற்றிய கண்டுபிடிப்பை வைத்து ஒரு வெண்பா!

சொற்பிழை பொருட்பிழை யிருப்பினும் பொறுத்தருளிக் கோடி காட்டுக! தளை தட்டினாலும் தலை தட்டாமல் கூறுக!

ஈரேழ் உலகைச் சூலகத்தில் இட்டவள்
சீராய் விரித்த வியன்செயல் ஓதுவோம்
கூராய் குறுக்கி, பலகணியில் நோக்கிலும் (அதன்)
தீரா அழகே/அறிவே சிறப்பு

[இரண்யகர்ப்பம் போன்ற பேரண்டம் வெடித்து வந்ததை, தெரிந்தவற்றைக் கொண்டுக் காணும் போதும், அதன் அழகு பீடுடையது.]

ஏந்திழையின்பொன்சூல் வெடித்தே விரிய
இழையெங்கும் சூழ்கொண் டுழன்றுப் பொடிக்க
மழையாய், களிகொண்டத் தூள்கூடி கூட்டுத்தூள்
விசைபெற்றே ஆன தணு!

[பெருவெடிப்பு சூல் கொண்டு வெடித்தப்பின்பு, ஆற்றல் இழைவடிவாக இருந்து, அதனின்று மென் துகள்கள், அதனின்று வன் துகள்கள், அணுவும் உண்டானது ]

அணுக்கள் அணுக்கமாகி ஈங்குப் பொருளமைய
ஆழியது வெந்தது போல் கோளமெங்கும் விரிய
இணுங்கிய தூள்கூடி விண்மீனாய் ஆகியே
ஈன்றவே தீப்பிழம்(பு) உலகு.

[அணுக்கள் கூடி ஒளிப்பிழம்பாகப் பொருளாகவும், அவை கூடி விண்மீன் உண்டானது]

விண்மீன் உமிழ்ந்த ஒளிவெளி செல்ல
விழுகூன் கிழமீன் உளதில் இடுங்கிட

How do you turn WiFi on in the Windows 8

Suddenly Windows 8, WiFi off was the status and wasn’t able to use Wifi Networks!!

http://img694.imageshack.us/img694/2959/62721723.png

Tried many fixes but nothing worked out.. the below is what helped me solve the issue..

Find “Window Power Shell” using Windows + F key.. run.. the command below

get-Wmiobject -class win32_networkadapter -namespace root\CIMV2 | where-object {$_.Name -match “Wifi” -or $_.Name -match “wireless” -and $_.name -notmatch “Microsoft Virtual WiFi Miniport Adapter” -and $_.netenabled -eq $false} | % {$_.enable() }

Now right click wifi network and diagnoze and fix to make wifi on

The serial key generator for Flex / AIR product to licence the RIA Product

http://code.google.com/p/codegenas3/

The project uses MD5 Encryption to generate the serial key, specific to Machine. The Unique key on system basis is generated and respective serial key is verified with the MD5 Checksum. Can be used on Flex / AIR products selling.

Also, uses SharedObject to store the unique System Key

Usage:
import adams.dev.MD5;
var reg:MD5 = new MD5();
reg.registereduser – > status of user registration
reg.skey – > serial key of the end user
reg.setRegKey(reg.skey); – > to enable the product

Note: The project is 3 years older work done by me.

set maintainAspectRatio true for Spark Image

To use maintainAspectRatio true in your Spark Image, use the fillMode=”scale” and scaleMode=”letterbox”

<s:Image id=”img” smooth=”true” fillMode=”scale” scaleMode=”letterbox” />

due to : spark.primitives.BitmapImage

private function get maintainAspectRatio():Boolean{
return (_scaleMode == BitmapScaleMode.LETTERBOX && _fillMode == BitmapFillMode.SCALE);}

iOS Packaging from Flex

My latest experience on converting Flex App to iOS, might be of use for beginners.

Debug version ipa generation is faster than rest, make sure you select Ad Hoc Distribution for testing the app on any device with Developer licence and Developer Provisioning Profile.

Make sure you use Mac for porting the application with Apple’s iPhone Configuration Utility, otherwise with windows use iTunes for porting the app into Device.

Reason:

You cannot install IPA files to the device via Apple’s iPhone Configuration Utility on WIN, got error “Could not install application on device. Error kAMDReceiveMessageError”. Workaround is to install IPA with iTunes on Windows or iTunes/iPhone Configuration Utility on Mac OS (2810687) (source : http://kb2.adobe.com/cps/891/cpsid_89107.html)

Move Scroll bar on left side Flex4

I struggled a lot, but fixed it with easy tweak.
s:List Property -> layoutDirection=”rtl”
Note, in case you were using itemRenderer , make the reverse there to avoid arabic right to left effect by :

Parallel Computing in AS3 //P

Managed to create a Master – Slave architecture between a group of SWF Files.
This group will have a Master SWF which will command other slave swf’s to do certain processing.

This architecture might be helpful in distributing the processing to many files thus reducing the Memory being occupied in a Single SWF.

With IoC in proper form in future, will be successful editing the Slave SWF’s Dynamically.

Code for Master : https://gist.github.com/9bd094ac172d336004c6

Code for Slaves : https://gist.github.com/a840cea1258e019176d8

This Architecture avails running multiple threads with different SWF files at same time

Things i learnt new from ACE -Flex4

ACE exam was a good learning experience for me, I came to learn about these new things yesterday.

saveCache is used in LCDS for offline mode saving.
Native Platform style is default setting for AIR.
FileMode.Update is used to make the both file writing and reading.
AcceptDragDrop is the method used to accept an DragObject and DoDrag is to initiate the dragging.
SQLConnection is the class used for setting SQLLite into write mode.
SQLStatement class property “text” is used for the sql querying purpose.
mouseDownEffect also can be used to set the Effect on MouseClick.
widthInChars is new property for TextInput which can be used to set width.
AIR can access the methods of loaded SWF by default.

Flex 4 ACE Questions

Passed ACE Certification with Flex4.

The differences of Flex3 and Flex 4 certifications
1/ more questions – 59 questions (previously 50)
2/ more time – 90 minutes (previously 60 min) Don’t bother about time factor you will have at least 30 minutes spare time for review.
3/ UI have more share among questions 35 %
4/ In Flex_Exam_Guide – They didn’t mentioned about LCDS, but we got Questions from LCDS too.

Tips:
1/ Do use attest, as it is the only resource we have for mockup
2/ Unlike Attest the questions will be in shuffled order
3/ While you attend ACE, don’t forget to use “Flag for review”, whenever you have doubt on your answer.
4/ The Questionnaire will be different for everyone

The below are some important topics, these areas required to be refreshed before attempting ACE.

LCDS
RemoteObject vs. Webservice vs. HTTPService

Flex3
[RemoteClass],[Bindable] Metadatas,E4X xml query, Labelfunction and Labelfield usage,Custom Event, Producer, consumer, validator,TabNavigator ,viewstack, setStyle, BlendMode, Modules vs. Sub Applications and formatter

OOPS
Interface, Encapsulation, Design patterns, access modifiers, Constructor and getter setters

AIR:
native platform in AIR Application,File management in AIR, Preloader, Drag and Drop in AIR, Security Sandbox in AIR, SQL Lite in AIR, create a Native AIR Application, Badge Installer in AIR

Spark :
working with state, ArrayList vs. Arraycollection, Animate, constraint layout in Spark Components, orientation of Child components,effects, create a custom component, Two-Way Binding, IVisualElement, ItemRenderer, LayoutBase, SkinnableComponent, TextInput, CSS namespace declaration, Descendant ID Type Class CSS types and Group

Dynamic Injection on runtime using BeanFactory

Met with requirement to inject object dynamically at runtime based on Push Message received.

Had a bit hard time finding solution, unusual with Swiz Framework.
Thought of sharing my experience here..
Step 1: In swiz Context assign the bean factory to your Bean Class

messenger.beanFactory = this.beanFactory;

Step 2:
In your bean class, Implement Interface IBeanFactoryAware
public class NativeMessenger implements IBeanFactoryAware

Step 3:
To Satisfy the implementation add the below code:
private var _beanFactory:IBeanFactory;
public function set beanFactory( beanFactory:IBeanFactory ):void{
_beanFactory = beanFactory;
}
Step 4:
Got access to Beanfactory
public var dynamicDAO:AbstractDAO;
protected function consumeHandler(event:MessageEvent =null) : void
{
var daoName:String = event.message.headers[“dynamicdao”];
dynamicDAO = _beanFactory.getBeanByName(daoName).source as AbstractDAO;
}

Now the dynamicDAO is assigned with the bean dynamically based on the consumer Message.

Flash Builder Network Monitor Bug

When a sequence of service calls made to server using, Blaze DS.

I got the below error, where as i used to get the result handler and fault handler responses for the same request.
There was nothing wrong in server side,
[FaultEvent fault=[RPC Fault faultString=”Error #2006: The supplied index is out of bounds.” faultCode=”InvokeFailed” faultDetail=”null”] messageId=”” type=”fault” bubbles=false cancelable=true eventPhase=2]

At last, i got it by disabling the Network Monitor of Flash builder things were back in shape..

Flex4 Module Loading

Tried out module loading in Flex 4 with Swiz, posted the code in Github link.
Hope, this is useful while using modules with Flex4.
Usage:
On change of moduleIndex the new module will be loaded on stage, the example is an alternative for viewStack elements loading.

How to Modify SWF without Recompilation

I could n’t access my Laptop last week, but i had some urgent work to do (recompile a old SWF). Here is how i did it.

This post is just a reference and guide based on the Post.

Find the Point which you want to modify using any of the available SWF Decompilers

Decompress the SWF using java.util.zip.DeflaterInputStream : Java Source Code file link

Jar File Download Link

Usage :  java -jar SWFCompress.jar c 'YourSWF.swf'

Download the Nemo440.AIR , to view the hex code.

Notice the exact place of the code to be modified using

The conventions of u30 encrypted Hex code is provided by Adobe.

Download any Free Hex Editors like HxD, to edit the SWF

Find the code part and modify the -decompressed SWF

Compress the decompressed SWF, back to the form, using SWFCompress.jar.

Usage :  java -jar SWFCompress.jar d 'YourSWF.swf'

Now the re compressed SWF is ready to go. Have Fun Cracking, Hacking SWF’s

Project: Swiz DAO

Libraries Used: Swiz, AS3Signals and FoomongerSwizFramework.

Objective:

To create GenericDAO framework, like IBM Generic DAO (Java /Spring/ Hibernate)

About GenericDAO:

DAO is the Object which manages to perform CRUD Operation and other Common

Operations to be done over a ValueObject ( known as Pojo in Java ).

GenericDAO is a reusable DAO class which can be used generically.

Goal:

In IBM GenericDAO, to add a new DAO, the steps to be done is simply,

Add a valueobject (pojo).
Add a hbm.xml mapping file for the valueobject.
Add the 10-line Spring configuration file for the DAO.

Similarly, in AS3 Project Swiz DAO. We want to attain a similar feet of achievement.

Client Side GenericDAO model:

As we were working on a Client Side language, also we should be managing a persistent object Collection (for every valueObject) .

Usage:

<swiz:Prototype name=”personDAO”

constructorArguments=”{[‘person’,personProcessor]}” type=”{AbstractDAO}”

singleton=”true”/>

Added, How it works in Github: DI Mechanism Link

Generic DAO in AS3

Built an AS3 Project to Work with GenericDAO using Swiz and AS3Signals

The project was inspired by Java Spring Framework:
IBM Generic Dao

The project uses the benefits of DI provided by Swiz 1.0.
The Deferred Instantiation of Swiz builds DAO Object only when [Inject] keyword is used.

Also, uses the latest Spark SkinnableComponent Framework for the View Part with Passive View.

The Source can be downloaded from SwizDAO Git
The below is the code from Swiz Context for a DAO Object:

<swiz:Prototype name=”taskDAO” constructorArguments=”{[‘task’,taskProcessor]}” type=”{AbstractDAO}” singleton=”true”/>
