.Net vs Java

The purpose of this post is the answer the age old question “Should I use Java or .NET?”  What are the advantages of each?  What are the disadvantages of each?  How should corporations decide which platform to use?

.NET platform

.NET applications are built by developing in any of the .NET languages such as C#, VB, or C++, which is then compiled into the CIL (Common intermediate language) byte-code.  Next, the CIL is converted into assembly which can then be executed on any Windows machine.

Java platform

J2EE applications are built by developing in Java only, which is then compiled into Java byte-code.  The intermediate byte-code is then converted to assembly using the JVM (Java Virtual Machine).  Unlike the .NET platform, however, the assembly code created from the JVM can run on any platform, including Windows, Unix, Solaris, or Mac OS.

Platform dependency

The major difference between Java and .NET is their platform dependencies.  .NET applications can only be run on Windows, while Java applications can be run on any machine.

Cost

The next major difference between Java and .NET is cost.  Since Java is open source, it’s completely free to develop and deploy Java applications.  It’s most popular IDEs like Eclipse and JBuilder are also free.  Furthermore, since Java applications are platform independent, they can be ran on UNIX machines, which is a free OS.  Essentially, the only cost associated with running Java programs would be the cost of hardware.

.NET applications, on the other hand, can only run on Windows machines, so Windows Server licenses will need to be purchased.  Unlike the Java platform which leverages free IDEs, .NET applications are built with Visual Studio, which is also requires a paid license.

As a result, small companies and startups are much more likely to have J2EE frameworks than .NET frameworks simply because it’s 100% free to develop Java applications.

Corporate infrastructure

Unfortunately, whether to choose the .NET platform or the Java platform isn’t always under your control.  In the corporate world, it’s very common for corporations to acquire other companies.  As a result, even if the corporation in question was originally built on a Java platform running on all UNIX machines, after a number of acquisitions that same company might now have a whole farm of UNIX, Solaris, and Windows machines.  In other words, larger corporations tend to be made up of both Java and .Net applications.  This isn’t necessarily a bad thing, but it sure can complicate your IT department!

Interoperability

This is sometimes an overlooked topic in the Java vs .NET debate –  .NET applications can theoretically be written in many different languages, including C#, VB, and C++ to name the major ones.  On one hand, this might provide you with the flexibility to hire programmers with different skill sets, allowing say a C++ developer to build certain portions of an application, and a C# developer to build other portions of an application.  Like any double edged sword, however, this can cause problems with maintainability.  The more languages that your application is built in, the harder it will be to keep the correct proportion of developers with each skill set to maintain the code when changes need to be made.

Java applications, as mentioned before, are only developed in Java.  This means that you won’t ever have the problem of training your developers in different languages, spending your company’s time and money.  It also makes the scalability of your applications much easier to handle, because if you need more developers, you simply hire more Java programmers.

GUI

Another difference between .NET and Java is the way that GUIs (Graphical User Interfaces) are handled.  .NET GUIs are somewhat easier to develop because they can directly access the graphical components of the Windows OS.  Although Java Swing and SWT (Standard Widget Toolkit) enable developers to create GUI elements on any platform, it is somewhat more cumbersome to manage than .NET

RIA dependencies

Finally, another difference to take into consideration is the emergence of new RIA (Rich Internet Application) technologies like Adobe Flex, Microsoft Silverlight, ICEfaces, and Javascript libraries like jQuery, YUI, and ExtJS.

If you’re building web applications using Adobe Flex or ICEfaces, you’ll need the Java platform.  If on the other hand you want to develop RIA applications using Silverlight, you’ll have to use the .NET platform.  If your web applications will be built using a Javascript library like jQuery, either platform will be just fine!

Conclusion

The reason that the Java vs .NET debate continues to rage on is simply because both platforms are excellent.  There’s nothing that one platform can do that the other can’t do.  But, under the certain circumstances explained above, it is sometimes advantageous to choose one over the other.

Mac OS X Lion

Lion is a significant step forward for Mac OS X, but it's not without its problems. Features such as Mission Control, Resume, Auto Save and Versions will prove incredibly useful over time. Launchpad may prove its worth, but even if it remains unused, it's not in the way. Many Mac owners will miss Rosetta, but its demise was inevitable. Not so Front Row, which didn't need to be dropped at all. Maybe Apple will put it in the App Store as a free download.

Despite a few teething troubles (most notably breaking third-party NAS compatibility and a few questionable interface decisions), Lion is definitely worth the upgrade. Like most OS upgrades it will probably really shine after its second or third update, but unless you're running PowerPC applications you can't be without, there's no need to wait.

Cloud Computing

Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more inefficient computing by centralizing storage, memory, processing and bandwidth.

A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc. You dont need a software or a server to use them. All a consumer would need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud ( internet) and is totally managed by the cloud service provider Yeah , Google etc. The consumer gets to use the software alone and enjoy the benefits. The analogy is , 'If you need milk , would you buy a cow ?' All the users or consumers need is to get the benefits of using the software or hardware of the computer like sending emails etc. Just to get this benefit (milk) why should a consumer buy a (cow) software /hardware ?

Cloud computing is broken down into three segments: "application" "storage" and "connectivity." Each segment serves a different purpose and offers different products for businesses and individuals around the world. In June 2011, a study conducted by VersionOne found that 91% of senior IT professionals actually don't know what cloud computing is and two-thirds of senior finance professionals are clear by the concept, highlighting the young nature of the technology. In Sept 2011, an Aberdeen Group study found that disciplined companies achieved on average an 68% increase in their IT expense because cloud computing and only a 10% reduction in data center power costs.

LG Optimus 3D

The LG Optimus 3D is a beast. That's normally meant as a compliment, but in reality, being a beast is a bit of a double-edged sword. Sure, you're big and powerful -- enough to rip your shirt open at the slightest provocation, at the very least. But you're also more than a little ugly and difficult to get on with. Don't believe the fairytales about the beast going off with the princess after she's discovered he has a heart of gold. Girls are far more fickle than that.

Ahem. We were talking about the LG Optimus 3D, weren't we? Let's start with that all-consuming power. The Optimus 3D has a dual-core 1GHz processor, which is more than capable of most tasks that you throw at it, including 3D 720p video capture. It has 8GB of internal storage, a SD card slot for expanding that further, and all the usual HSDPA, Wi-Fi and Bluetooth connectivity options.

The display is pretty impressive too -- a larger-than-average 4.3-inch capacitive touchscreen, running at 480 x 800 resolution. It copes well in sunlight, and you'll be surprised how much of a usability improvement the larger screen delivers when it comes to hitting the right key on an on-screen keyboard or playing games.

Unfortunately, rather than use that display to show off stock Android's rather tasty design, LG's chosen to slather everything in its own user interface, which is ugly as sin. It's square, it's squat, it's outdated, it's not pleasant to use, and worst of all it replaces several bits of perfectly good software included by default in Android.

One example is the News app. Google's News and Weather app detects your location automatically, picks a selection of local media sources, and links to a wide range of stories in different categories. You click them, and they open in the browser where the news source gets advertising revenue.

LG's app, on the other hand, demanded that I manually set a location and some categories before I got to see any news, and once I had, gave me nothing but an RSS feed from Sky News in the "Top Stories" category. Clicking through to a story gave me a paragraph, which I then had to click through again to get to the actual story.

Then there's the 3D. Let's not beat around the bush here -- it's a useless gimmick. Sure, it's fun for 30 seconds, and it'll earn you brief credibility if you wave it at your friends in the pub. But even aside of the argument as to whether it's nicer to look at than 2D, it doesn't add any actual functionality -- just novelty.

The only place where you can make an argument that 3D is actually worth using is in the games on the phone. Here, powerups whizz out of the screen, golf balls disappear satisfyingly into the distance and cars slide convincingly around corners. It's a pity the games themselves aren't much cop, but crucially the 3D does genuinely improve the experience. Enough to want to be tied into a lengthy contract for? Perhaps not.

It'd be wrong not to mention, too, that the Optimus 3D has launched with an outdated version of Android -- version 2.2. Version 2.3 has been available for the best part of six months, so it's ridiculous to see phones arriving still packing the previous edition. There's no real excuse for this, except that LG's bloatware probably doesn't work with the latest version of Android yet.

Finally, we got surprisingly poor battery life from the 1,500 mAh Li-Ion battery. You might be expecting that the big screen and meaty processor were sucking up the juice, but a glance at Android's battery use graph suggested that it was actually cell standby causing the power drain. That's a little surprising, and could suggest there's some sort of software glitch, which is hopefully fixable with a patch.

Conclusion

So, what have we learnt? We've learnt that the LG Optimus 3D is powerful, and large. But we've also learnt that it's ugly, bloated, a little outdated, and makes your eyes hurt if you look at it for too long.

The LG Optimus 3D is a beast, but it's also pretty beastly. 

ASP or PHP?? What is best??

 

ASP and PHP are both programming languages that are commonly used to create websites. Unlike the usual static html web pages, ASP and PHP websites are more dynamic and can allow users to interact and exchange information using the website's databases.

ASP is the short term for Active Server Pages, a type of program that works with Microsoft alongside IIS or Internet Information Server. ASP needs a Microsoft Server for the website to work. On the other, PHP or Hypertext Preprocessor, runs using Linux or Unix server. The more updated PHP programs can now run on an NT server.

PHP programs can also run in Windows, Solaris, Unix and Linux while ASP can only work with Window-based platforms. Just recently, ASP can now run on a Linux platform given that there is an ASP-Apache program installed on its server.

If you were a programmer adept with the C++ language, you would probably be more comfortable using PHP than ASP. PHP uses C/C++ as base language and most syntax are similar to each other. Because a big chunk of programmers are still using C++ language, PHP are by far more popular than ASP.

ASP is very much similar to the syntax and interface of Visual Basic programming. This is basically because Visual Basic is basically correlated with Microsoft products and programs. So if you were a programmer, choosing between ASP and PHP would basically depend on which language you are more adept with.

When it comes to costing and expenses, ASP programs needs to run on Windows with IIS installed on the server. You need to purchase both of these components in order for ASP to work. On the other hand, a PHP would only require running on a Linux server, which you can get at no cost.

PHP is very much flexible when it terms of database connectivity. It can connect to several databases of which the most commonly used is the MySQL. Note that MySQL would not cost you a thing to use. But if you were to use ASP, you need to purchase MS-SQL, which is a Microsoft product.

Loading speed is a big factor in maintaining a website. If you are particular about speed, then you need to go with PHP. PHP codes runs much quicker than ASP basically because it runs in its very own memory space while ASP uses an overhead server and is uses a COM based architecture.

In working with PHP, most tools associated with the program are mostly open source software so you need not pay for them. As for ASP, you might need to buy additional tools to work with its programs.

In conclusion, both PHP and ASP have its own advantages and disadvantages. It basically depends on which part of developing a website you are most concerned with. Are you worried about the cost of creating your website? Do you want to use a programming language that you are more familiar with? Do you want a more stable and faster website? Choosing between ASP and PHP basically depends on your own personal preference. It doesn't hurt to confer with other programmers or webmasters and research more information on which programming would best fit the requirements of your website.

Top Brands of Tablet PC

What is a Tablet PC?

• A tablet personal computer or tablet PC is tablet-sized computer that also has the key features of a full-size personal computer. A tablet PC is essentially a small laptop computer, equipped with a rotateable touchscreen as an additional input device, and running a standard (or lightly adapted) PC operating system like Windows or Linux. The term was made popular with the Microsoft Tablet PC concept presented by Microsoft in 2001. Today, the term tablet is also used to refer to computer-like devices operated primarily by a touch screen but not intended to run general PC operating systems or applications.
