Synch Framework vs. Gears

Microsoft Sync Framework
is a data synchronization platform from Microsoft that can be used to synchronize data across multiple data stores. Sync Framework can be used for offline access to data, by working against a cached set of data and submitting the changes to a master database in a batch, as well as to synchronize changes to a data source across all consumers (publish/subscribe sync) and peer-to-peer synchronization of multiple data sources
Unlike Gears, which Google launched in late May, Sync Framework's purpose is not only to provide a way to save data both locally and in the cloud -- a prerequisite for enabling a Web-based application to work offline. "It's a general purpose tool. It's not just for applications, but also for services and devices," Carrabino said
According to the download site, Microsoft Sync Framework will enable "collaboration and offline scenarios for applications, services and devices." That includes P2P synchronization of relational databases, NTFS/FAT file systems and all sorts of data ranging from contacts to music, videos, and user settings

We're doing something different from Google, said Anthony Carrabino, a senior product manager for SQL Server. "Sync Framework is really a tool that lets developers build applications that can sync any data -- files, contacts, it could be anything -- over any type of protocol.

Google Gears
is software offered by Google that "enables more powerful web applications, by adding new features to your web browser. It allows some online files to be used offline

it's important to note that because the database portion of Gears is really just a client-side database accessible from javascript, there's nothing in Gears that specifies a specific server-side implementation, or even a specific server api. Thus, doing things like the data partitioning you describe are up to the developer, as is interfacing with the server in general

Several web applications from a variety of companies have used Gears at some point, including Google (Gmail, YouTube, Docs, Reader, Picasa for mobile, Calendar, Wave), MySpace (Mail Search), Zoho (Writer, Mail), Remember The Milk, and Buxfer.[15] WordPress 2.6 added support for Gears, to speed up the administrative interface and reduce server hits

Version Control Systems

Version Control System (VCS) is a software that allows to manage changes of documents, programs, images and other information that is stored in form of computer files.

Some popular Version Control Systems:
■Subversion - cross-platform open source VCS with great User Interface implementations (TortoiseSVN is the most known implementation for Windows shell integration).
■Git - open-source VCS for distributed development that does not require a central server, yet lacks a convenient UI.
■Mercurial - yet another distributed open source version control system which is less popular than Git (5 times less popular, if you trust Google).
■TFS - is a Microsoft product offering source control, data collection, reporting, and project tracking, and is intended for collaborative software development projects. It is available either as stand-alone software, or as the server side back end platform for Visual Studio Team System (VSTS).

Martin Fowler conducted the survey on 99 developers in his company ThoughtWorks and its the result
The results were this:

Tool	Best	OK	Problematic	Dangerous	No Opinion	Active Responses	Approval %
Subversion	20	72	6	1	0	99	93%
git	65	19	1	0	14	85	99%
Mercurial	33	27	2	0	36	62	97%
ClearCase	0	3	14	41	41	58	5%
TFS	0	0	32	22	44	54	0%
CVS	0	14	59	11	15	84	17%
Bazaar	1	13	3	0	80	17	82%
Perforce	1	26	16	1	54	44	61%
VSS	1	1	11	64	22	77	3%

SQL Injection

SQL injection is a code injection technique that exploits a security vulnerability occurring in

the database layer of an application

Example
SELECT * FROM users WHERE name = 'a';DROP TABLE users; SELECT * FROM userinfo WHERE 't' = 't';

If this code were to be used in an authentication procedure then this example could be used to force the selection of a valid username because the evaluation of 't'='t' is always true.

Anders Hejlsberg author of C# and Turbo Pascal

Anders Hejlsberg was the original author of Turbo Pascal, the chief architect of Delphi, and currently works for Microsoft as the lead architect of the C# programming language.

In 1996, Hejlsberg left Borland and joined archrival Microsoft. One of his first achievements was the J++ programming language and the Windows Foundation Classes; he also became a Microsoft Distinguished Engineer and Technical Fellow. Since 2000, he has been the lead architect of the team developing the C# programming language.

He received the 2001 Dr. Dobb's Excellence in Programming Award for his work on Turbo Pascal, Delphi, C# and the Microsoft .NET Framework.

Aspect Oriented Programming

In computing, aspect-oriented programming (AOP) is a programming paradigm in which secondary or supporting functions are isolated from the main program's business logic. It aims to increase modularity by allowing the separation of cross-cutting concerns, forming a basis for aspect-oriented software development.

AOP addresses the problem of cross-cutting concerns, which would be any kind of code that is repeated in different methods and can't normally be completely refactored into its own module, like with logging or verification. So, with AOP you can leave that stuff out of the main code and define it vertically like so:

function mainProgram()
{ var x =  foo();
 doSomethingWith(x);
 return x;
}

aspect logging
{ before (mainProgram is called):
  { log.Write("entering mainProgram");
  }

 after (mainProgram is called):
  { log.Write(  "exiting mainProgram with return value of "
              + mainProgram.returnValue);
  }
}

aspect verification
{ before (doSomethingWith is called):
  { if (doSomethingWith.arguments[0] == null)
     { throw NullArgumentException();
     }

    if (!doSomethingWith.caller.isAuthenticated)
     { throw Securityexception();
     }
  }
}

And then an aspect-weaver is used to compile the code into this:

function mainProgram()
{ log.Write("entering mainProgram");

 var x = foo(); 

 if (x == null) throw NullArgumentException();
 if (!mainProgramIsAuthenticated()) throw Securityexception();
 doSomethingWith(x); 

 log.Write("exiting mainProgram with return value of "+ x);
 return x;
}

There are two different ways AOP programs can affect other programs, depending on the underlying languages and environments:

(1) a combined program is produced, valid in the original language and indistinguishable from an ordinary program to the ultimate interpreter

(2) the ultimate interpreter or environment is updated to understand and implement AOP features.

The following are some standard terminology used in AOP:

• Cross-cutting concerns: Even though most classes in an OO model will perform a single, specific function, they often share common, secondary requirements with other classes.
• Advice: This is the additional code that you want to apply to your existing model.
• Pointcut: This is the term given to the point of execution in the application at which cross-cutting concern needs to be applied.
• Aspect: The combination of the pointcut and the advice is termed an aspect.

AOP has been implemented (in either the language itself or as external library) for the following programming languages & tools:

1. Java AspectJ
2. .Net framework (C# & VB.Net)
3. C/C++
4. PostSharp

Alice Teaches Kids To Program

Computer scientists have found a way to make computer programming visual. Instead of using numbers, letters, and punctuation like other programming languages, Alice uses three dimensional figures placed in a storyline. Users select from a gallery of characters and backgrounds, then select the character's movements through a pulldown menu.
Alice is an educational software that teaches students computer programming in 3D environment.

Sun Microsystems presented its 2009 Duke’s Choice Award for Java Technology in Education to Carnegie Mellon’s innovative Alice software system during the JavaOne conference at San Francisco’s Moscone Center

PostgreSQL support Arabic

PostgreSQL:
is an object-relational database management system (ORDBMS). It is released under a BSD-style license and is thus free software. As with many other open-source programs, PostgreSQL is not controlled by any single company, but has a global community of developers and companies to develop it.
Problem:
PostgreSQL cannot support arabic fonts as it used SQL-ASCII Encoding as default.
Solution:
You just choose UTF-8 encoding to enable DB to be arabic.
You can now make a simple C# application that connect to postgre DB to check if it run right or no?You have recourse to simple application of Adrian Pasik to test

القضاء الإدارى يقضي بحجب مواقع الإنترنت الإباحية في مصر

قضت محكمة القضاء الإداري بمجلس الدولة في جلستها المنعقدة الثلاثاء بإلزام كل من وزارة الاتصالات والجهاز القومي لتنظيم الاتصالات بحجب المواقع الإباحية على شبكة الإنترنت، وذلك في الدعوى المقامة بهذا الصدد من أحد المحامين ويدعى نزار غراب.

قالت المحكمة في حيثيات حكمها: إن الدستور المعدل، مسايراً في ذلك الاتفاقات الدولية المقررة لحقوق الإنسان قد كفل حرية التعبير بمدلوله العام،وما توخاه الدستور من خلال ضمان حرية التعبير هو أن يكون التماس الآراء والأفكار وتلقيها عن الغير ونقلها إليه غير مقيد بالحدود الأقليمية على اختلافها، حسبما ذكرت وكالة أنباء الشرق الأوسط.

وأضافت :إن الدستور أكد على ضرورة ألا تنحصر حرية التعبير في مصادر بذواتها، بل قصد أن تترامى أفاقها وأن تتعدد مواردها، إلا من الأغلال أو القيود التي تفرزها تقاليد المجتمع وقيمه وثوابته بحسبان أن الحريات والحقوق العامة ليست حريات وحقوق مطلقة وإنما مقيدة بالحفاظ على الطابع الأصيل للأسرة التي هي أساس المجتمع والتي قوامها الدين والأخلاق والوطنية والتزام الدول والمجتمع بمراعاة المستوى الرفيع للتربية الدينية والقيم الخلقية والوطنية والتراث الحقيقي للشعب والآداب العامة.

وأشارت المحكمة إلى أنه بشبكة الإنترنت مواقع إباحية تنفث سمومها في نشر الرذيلة بين طوائف المجتمع المصري بالصوت والصورة، بما يهدم كل العقائد الدينية الراسخة والقيم الأخلاقية والآداب العامة.

وأوضحت أن الإبقاء على هذه المواقع وعدم حجبها يهدم القيم المشار إليها ولا يمكن أن يدور ذلك في فلك حرية التعبير لأن ما يعرض على هذه المواقع يعد أبرز صور الإخلال بالمصالح العليا للدولة والأمن القومي الاجتماعي، ومن ثم كان لزاماً على الإدارة اتخاذ كافة الوسائل اللازمة لحجب هذه المواقع عن المواطن المصري ويضحى القرار السلبي بالامتناع عن ذلك اعتداء صارخاً على أحكام الدستور والقانون.

الساحر اليمني التائب

فيديو حلقات الساحر اليمني التائب التي عرضت على قناة المجد

الساحر اليمني التائب نشأ في أسرة متأثرة بالسحر وكان والده ساحراً شهيراً، وبالرغم من امتهانه السحر والشعوذة وهو في بداية شبابه بفعل اصرار والده على ان يورثه مهنته لتذهب جهود والدته التي حاولت إبعاده عن هذا الطريق ادراج الرياح، ومع ذلك برع في أمور السحر والشعوذة وامتلك القدرة على مخاطبة الجان والشياطين وتسخيرهم لصالحه طوال عشرين عاماً، قبل ان يتوب ويهتدي الى الطريق الحق..

من اعماله السحرية الذي كان يشتكي من عدم حمل زوجته بأنه قادر على علاجها، وهذه كانت البداية وكان يوهم الناس بأنه يعلم بكل شيء بمساعدة الشياطين والجان فكان يزرع في قلوبهم الخوف والرعب من تصرفاته وأفعاله وكان يصور لهم أنه يغرس «الجنبية» خنجر يمني في جسمه وهذا غير حقيقي
