2012 had been a phenomenal year for Android as explained in an infographic posted by a search monetization agency. According to the infographic, while there were about 425,000 apps in Google app during the start of the year 2012, the count nearly doubled to about 800,000 by the end of the year in Google Play store. The daily revenue of Google Play increased by about 43% within 4 month span between August - November 2012 and reached upto $3.5 Million.
Enterprises are also leveraging the benefit of Android application because of the availability of an ample variety of application. The cause of such a drastic change in the application deployment could be credited to third party application development practice of the Android community. Any developer with any application having any kind of utility can present an application in Google Play Store, as long as the app follows the guidelines and policies of the store.
IT department has also experienced a drastic shift in its operational practices as its workforce is not bound to stay within the campus of the organization anymore. Employees can remotely monitor, manage and administrate the IT related tasks and resolve issues from their Android device.
Here is a list of the best Android applications of last year for IT professionals:
  • Linux Monitor: This app helps IT workforce to monitor and manage their Linux Server activities. Different tasks like monitoring the CPU load, RAM and disk usage, and even network/port activity can be tracked remotely through an Android enabled device. Though it's a paid app, users can download the trial version to get a feel of the application and the way it functions.
  • httpmon: To monitor http servers, specifically, this app is really helpful for IT managers and administrators. A user can customize a request URL with customizable conditions like content using substrings or wildcard characters and can also check the server with a simple ping. Notification actions like flash message, alert message, phone vibration or SMS can also be customized for the failure conditions using this app.
  • ConnectBot: This is another free android app for working with UNIX based servers or any other network component which can work properly with SSH/Telnet connections. Administrators can remotely connect with the server and can perform admin, maintenance and troubleshooting tasks using the command line interface of this app.
  • Cellica Database: Other than having roles and responsibilities on web servers, IT admins need to work upon the databases as well to create tables, to sort the selected tables and data filtrations. To conduct these database operations this application can be used, specifically for databases running on a Windows server. Moreover, this app provides an encrypted access to database location so its a secure mode of connection which protects the network intrusion.
  • ActiveDir Manager: Working on Active Directory of an organization has been made easy with this Android application as it lets the IT personnel to view and manage the users, group and machine from the device. Policies and access can be set from their application, resetting password and other basic admin tasks can be performed with this app. It is available as a free as well as a paid version with the difference that paid version allows us save the changes in setting and option of LDAP connection.
Android has significantly influenced the working practices of workforce inside an organziation as even after being a deeply customized platform, it has evolved in terms of security. Android 4.0 completely wiped out the security loopholes of the architecture in its mobile OS and result of which is that Android is emerging as a platform for business oriented applications as well.

How to Start a Website for Your Small Business

 By

Photo: 1.bp.blogspot.com
 
These days, a business just isn't a business without a website. Customers have grown to expect the convenience of online access, even in industries where a web presence doesn't immediately seem necessary. Hair cutters, farmers, electricians - even mom-and-pop institutions need websites!
The good news is that, as websites have become more necessary, they have also become easier to create. This year, hundreds of thousands of websites will be created, many of them by the entrepreneurs themselves. In the past, web developers were a necessity in a world of HTML and PHP (web coding languages), but these days anybody can create a website. And you can too!
The first step is probably the most difficult, but you don't need a computer to do it! The first thing you need to do is to think about what your website should look like. Before you spend a lot of time constructing the face of your business, you should probably decide what your website's function will be.

Once you've determined what your website does, it's time to try to figure out a simple way to design your site to meet those requirements.
Let's think of a concrete example. Let's say we run a business that delivers fresh baked cookies to people all across Ottawa. What would you like our website to do? Well, a good function for a website like that might be to have a place where people can order our cookies from their computers or phones. That's a great purpose for our website, and I think people would appreciate not having to call to secure some of our delicious white chocolate macadamia treats.

Once you have the primary function (in our case, it's cookie ordering), you can structure the rest of the pages around it. In our example, let's make the main page the cookie order page, and make it so that other pages are accessible through the menu. We could have an "about" page where we talk about why we started the business. We could have a "location" page where people can find out where our store is. We could even have an "apply" page where people can try their hand at becoming cookie deliverers like us!

Now that we've figured out the basic operation of our website, it's time to start building! Don't worry! It's easier than it sounds, and if you make a mistake, no one will notice. Don't worry about buying a domain name for now (we'll cover that in a second). Instead, go straight to a website like WordPress or Blogger.

Once places for teenagers to create emotional personal blogs where they talked about how angry they were about their parents, blog creation websites have recently become one of the easiest and most powerful website creation avenues. WordPress is generally regarded to be the better of the two mentioned above, so try that one if you're just starting out.

WordPress lets you pick from a range of free themes, many of which are of a very high quality. If you don't find anything that works for your website for free, you have a couple options: pay for a premium theme, or modify a theme to better suit your needs.
Premium themes are available from places like Templatic. In some cases, you can even get a team of specialists to work on your design for you.

But if you want to go the free route, you're going to be in for a bit of a hard time. Modifying themes means learning a bit of coding (ew!). Think of it like renovating your kitchen. If you want to do it yourself, you're going to have to study some electrical charts (and probably take out life insurance). Remember, if you can find a free theme that works for you, just go with that!

You can learn some basic HTML at places like codecademy.com, or you can just plunge right in, stripping things out of the code behind the website until things work the way you want.
You might want to have a code-familiar friend on hand to help you. You know... just in case things get a little tense around the house.

Once you're done all of that, it's time to make it official. Start shopping for a host! My favourite is Servage, but other options, like Canada's Netfirms are also quite good. Find a pricing structure that works for you. For a small business, you're probably looking at an investment of about 50 bucks a year. That's nothing huge in the grand scheme of running a business. You'll probably spend more on cookie trays in a month!

Plus, we can help! We offer security and peace of mind, as well as content for your new website venture. Check out our Wordpress page for more info.

What Changes Can We Expect in 2013 in the Mobile World?

 By

Photo: l2.yimg.com
 
Everyone has extremely high expectations in the mobile world in 2013, especially since 2012 was an amazing year for mobile. The truth is that the mobile industry is changing at a rapid pace, therefore we could see some incredible improvements in this modern industry that belongs to every mobile consumer worldwide.

It is a proven fact that the mobile trend has entered every aspect of our personal and professional lives. However, in order to see the practical ways that the mobile technology will affect and even change our lives this new year, it is important to study some global trends of the mobile world.
Interesting Mobile Trends in 2013

1. An Even Faster App Growth. More and more users have come to realize that using a mobile phone when accessing the Internet is way more easy and beneficial than using a laptop or a desktop PC. According to Forrester Research, the app Internet market is worth over $2.2 billion. Forrester's chairman predicted that this huge market will expand by over 80%. However, his point of view is not the same of many other marketing experts, who predict that the expansion won't be bigger than 50%.
All Android, iOS, Blackberry and Windows Phones have tens of thousands of apps that are promoted on Google Play or other smartphone app websites. Many talented programmers from all over the world are creating breakthrough apps that are breaking new ground in this market, so there's no other trend for mobile apps than an upward one this new year.

2. An Improved Browsing and Navigation Experience. A good example of such improvement was promoted by Kindle last year, when they introduced a new feature that allowed its readers to pick up reading from where they left off. This feature is similar to Google Docs' offline mode, which automatically saves your articles, so in case the computer suddenly shuts down, you can easily go on writing from where you left.

The results of all these improvements planned for this year will allow the mobile users have a top-notch browsing experience, being able to browse the Internet even in offline mode. It is predicted that the mobile Internet browsing will reach 1.5 billion users this year, while the desktop Internet usage will be only 1.6 billion. If the trend continues, most researchers believe that by 2015 the number of mobile users will reach 2 billion, while the number of people who access the Internet on their laptops will reach 1.7 per month. Therefore, it is imperative that the browsing experience and navigation experience to be the best possible, in order to satisfy even the savviest user.

3. Moving to the Cloud. Box.net, Dropbox and other modern cloud storage devices ease the process of connecting to your favorite media, including movies and TV, whenever you are on the go. On the cloud, you can keep together all your favorite games, TV shows, news, weather, social networking sites and music.

4. Wi-Fi. This new area of the mobile world will certainly continue its steady growth. According to some specialists, we might even see some access points and routers embedded in tablets and mobile phones. Moreover, the speed between mobile devices will increase, allowing for a better and faster data transfer, and consequently an improved user experience.

5. New Smartphones. In 2013, we will be certainly amazed by the new range of smartphones that will hit the headlines. For most of us it will be probably quite difficult to keep up, especially since new phones are announced on a weekly basis. However, on top of all, two phones are considered to be above all else: the one from Microsoft and the new release from Amazon. On the other hand, Nokia and Blackberry won't be pushed away so easily due to their new releases: RIM's BlackBerry 10 and Nokia's Lumia 920.

6. Mobile Video. Lastly, one final trend that will sweep across all nations this year is the over-the-top video trend, which will certainly make the mobile go global. More and more customers are abandoning their regular cable TV subscriptions for Hulu, Netflix, Amazon, Apple and other over-the-top Internet sources. Soon, we might even see smartphones that come with a TV receiver chip embedded in them.

There are many other changes we can expect in 2013 in the mobile world, but the trends showcased above are among the most important we will experience.

Mobile marketing is continually on the rise, especially since mobile users have taken over desktop Internet users. Check out more unique and relevant information about the tremendous power of mobile marketing by clicking on the following link: The Power Of Mobile Marketing.

Compact Flash Card Recovery and USB Flash Drive Recovery

Author: Hardley Thompson

Photo: s3.static.mymemory.co.uk

Compact flash cards and USB flash drive are small storage devices, easy to carry, used to gain additional storage capacity, to backup files or to transfer information from one device to another. These storage devices are reusable, can be erased and reused indefinitely without loss of existent data.

Data loss on compact flash cards or USB can occur through accidental deletion or formatting, from physical damage or virus attack, and the list can go on. The ideal case is when data was deleted or accidental formatted, because the files aren't completely erased. They are still there and can be recovered. USB flash drive recovery or compact flash card recovery can be done in companies specialized in data recovery.
As time passes we tend to depend more and more on technology and the reason for that is that these devices make our life simpler and easier. While there are many reasons for data loss, the evolving technology makes recovering accidentally deleted data from USB flash drives easier.

If your storage device has been under a virus attack, it is indicated that the files should be quarantined and the rest of the data transferred on your computer's hard disk.

Also, make sure that you or other people don't try recovering data if you aren't sure what are you doing or use the broken USB, because this could lead to permanent and irremediable losses. If we face with data loss we should seek a company that is specialized in USB flash drive recovery, compact flash card recovery or other similar devices. These professionals will help you easily recover data from damaged units. They use specific software programs that have been specifically designed for such such recovery operations and aren't usually available for sale for the general public.

If you get your hands on a USB flash drive recovery or compact flash card recovery software and want to try the recovery yourself, you must follow these steps:

For the recovery of deleted files there must be a "Deleted Recovery" option.
In case of accidental formatting you should use the "Format Recovery" option. From the partitions list, the software will choose your flash drive.

Clicking the "Scan" option will open a new window.  Remove the files needed form the folders available, then select the ones you need recovery for.

Click "Recover" in order to start the data recovery process. Recovered data can be stored on hard disk or any storage device other than the one in question.

Once the operation is finished click the "OK" button to complete  the  USB flash drive recovery or compact flash card recovery process.

Closing the page, in order to keep important data safe, it is not necessary to store them on a second storage device, it is advisable to have multiple copies stored on more than 2 devices to increase the chances of recovery data. Also if you are not sure what to do in this situation seek advise from professionals.

Printing Anything From Anywhere Is No Longer Impossible

 By

It's become often a necessity when using a smartphone, tablet, or laptop and is an essential part of your daily workflow. Let's face it that even in our "green" world printing is still required and is not likely to disappear any time soon. In many industries, such as legal, insurance, medical, pharmaceutical, and government a live "wet signature" on a printed page is still required to execute a contract. Gartner research predicts that over 90% of the Fortune 1000 will implement cloud-based printing for mobile employees by 2014.

Here are a few cases in point. You receive a spreadsheet attachment on your smartphone, or tablet and need a way to view the document without squinting. You've revised a large document just as your plane lands, and need to print it before you arrive at your business meeting. Or maybe you are just staying with family out of town, and need to print a boarding pass directly from your phone. Perhaps you purchased last minute show tickets and need to print the eTickets. Whatever the case, wouldn't you like to send a print job to the printer you have down the hall, or to a printer in an office supply superstore down the block, or even in your hotel's lobby? How about sending a document from Montreal to your own printer back in Vancouver?

Mobile printing technology now makes this possible. Printers with wireless or internet connectivity can communicate beyond a specific user or workgroup. And printer vendors and third party vendors; all happy to help you collaborate, remain productive and print when needed while in the office or on the road from your mobile devices; are providing solutions that use e-mail or cloud-based print servers as the backbone for sending print output. Large companies like Apple, Google, and HP have technologies that address issues such as reaching older printers, or finding places to print when you're on the road. There are also a number of manufacturer independent solutions available from Breezy, EFI, PrinterOn, Drivve, and Lantronix to name several.

With mobile printing apps enterprises can provide their staff with mobile device printing services within their own network. This can be important to enterprises with a significant investment in mobile devices or who are adopting BYOD. It is surly better than lugging around the laptop and then printing that important document for your next meeting.

Using the cloud services available with most mobile printing apps you can use enabled printers at locations such as hotels who provide the service in their lobby business centres. The cloud service of these apps will also geo locate the closest printer location and pinpoint it for you on your device. Apps are generally available for Apple, Android, Blackberry and PC devices. Users also have the option of printing from the Web by logging into their app's web server. You also have your home network covered as well. I can attest to mobile printing's reliability as my wife, I and guests use it in our home to print material from our smartphones and tablets.

I am convinced that these apps are a definite must for today's mobile device user.

Configuring a New Laptop

 By

Photo: news.it.ufl.edu

There are a lot of things to consider when you are shopping for that laptop, the two most important specifications however are going to be your processor and your RAM. Here I am going to explain some of the fundamental features of both so you can make a better choice when buying a laptop for yourself.

PROCESSOR (CPU)
Intel the world's largest semi conductor maker has begun the process of transitioning into a quad core line of processors. Their range is branded as Core i3, i5 and i7. If you are hunting for a bargain then you could choose its older Core 2 models, but you would be better off sticking to its latest range.
You could also consider a processor from Intel rival AMD which has a compelling range of products branded as Turion II and Athlon II. If you are a budget shopper then these processes are well worth considering and will serve the purpose for most tasks. The big difference between processors made by AMD is they are simply not as fast as those made by Intel and they tend to act as a drain on battery life.

The most important task is working out exactly how much processing power you need. In general the Core i3 or i5 are suitable for most people. If however you do a lot of video editing then you are going to need a more powerful processor. Gamers in particular believe they need a powerful processor but in practice can actually get away with a slower chip.
Quad core chips still cost a lot and also tend to drain battery life quite quickly. You can identify a quad core chip by the Q denoted next to the machine's model number. If you use your laptop as your main machine, and not taking it out on the road, or you are a gamer or video editor, the quad chip case becomes more compelling.

The decision over processor gets trickier when you are ordering a custom laptop from a manufacturer. You should as a rule avoid the most expensive chipsets on offer and go for the second or third least costliest chips. The increase in price is usually proportional to performance. You should not spend more than $150 upgrading a processor. If you are simply surfing the internet or word processing, even a dual core processor is more than adequate.

MEMORY (RAM)
4GB RAM is the standard memory offered by most manufacturers even on low end laptops and that is really all you need. Starting prices for a laptop with 4GB RAM are just under $500. In the past manufacturers used to make consumers pay through the nose when they upgraded the memory whilst custom ordering. More recently, this practice seems to have changed, and only Apple really still does this.

If upgrading your memory to 4GB costs you less than $90, which is what it costs separately, then you should definitely upgrade. Upgrading beyond 4GB is going to be expensive, and the only real reason to do it is if you are video editing, and even then it's still not absolutely necessary when you compare it against the expense. For a desktop, spending an additional $100 is no big deal, but for a laptop where it is going to cost you an additional $300 for 8GB, it's simply not worth it unless your laptop is your primary video editing device.

6 Best Tips To Develop An App For The Android Platform In 2013

By

Photo: cdn.androidpolice.com
 
A recent report by Gartner states that Android has captured over half of the planet's smartphone OS market share. Android app development provides an array of endless opportunities to its developers as it has a wide and fragmented user base. The good news is that even the tools of Android app development are getting updated keeping in mind the recent requirements and offering innovation development platforms for its developers.

Let's take a look at the 6 most vital things to keep in mind while developing an app for Android:

Develop Your Skills: Learn SQL, Eclipse and XML to create visually appealing and highly functional apps for your Android. All three technologies will allow developers to build intuitive apps with storage, productivity and visual features. Developers can fix future issues that may arise with Android apps. Thus developers must keep track of development software of Android apps.
Build For Multiple Screens: Create Android apps by keeping in mind various screen sizes and resolutions. Know all available screen sizes before you start building your app. An app developed for one screen size may not work well in a different screen size thus leading to inconsistent and unsatisfactory user experiences.

Use Latest Version: Developers must keep themselves updated with the latest version of SDK for Android app development. The latest versions can help fix many latent issues like bug fixes, performance related problems, resolutions and so on. In order to create a good app it is necessary to equip it with the most recent features and troubleshooting software for improved user experiences.
Power Consumption: Make sure to design your apps in a way that they consume less power. Whether you develop a free or a paid app make certain to design it for lower power consumption rate than that of computers. Ensure that your app does not kill the phone's battery life and annoy your users.

Make it Android Compatible: Build an app compatible with Android. Ensure that it can easily work using Android functions like it is easy to install and simple to work with. Android ensures that its app work as per the user requirements. For instance, app must close down when not in use and come back to life when the user taps or clicks back in for navigation. Moreover developers must make sure that your app is compatible with at least top 5 or top 3 versions of Android operating systems in order to deliver viable solutions to its users.

Test your App: Use Monkey to throw a stream of random tests to your app. Or, if you have time let random human users test your app and check for issues that might crop up. This is the most effective way to check for your app usability and appeal. This is the most crucial step before distributing or marketing your app as it a successful app is all about enhanced user appeal and function.

To conclude:
To develop robust and highly functional apps it is imperative for developers to use the most recent and reliable of the software. Remember to build apps for diverse customers and devices without compromising on the development aesthetics.

Sap Data Warehousing Solution

by:

Photo: praxa.com.au
 
SAP BW is a continuous data warehousing solution that uses former SAP technologies. This SAP BW is built on the Basis of 3-tier architecture and coded in the ABAP (Advanced Business Application Programming) language. This 3-tier architecture and code language uses ALE (Application Link Enabling) and BAPI (Business Application Programming Interface) to link BW with SAP systems and non-SAP systems.  
 
BW Architecture

The BW has three layers in it. The top layer is the reporting layer. This top layer may be BW Business Explorer (BEx) or a third-party reporting device. This BEx consists of two components: one is BEx Analyzer and other is BEx Browser.

BW Server is a middle layer that carries out three tasks: it administrates the BW system, stores data and retrieves the data. In The bottom layer it consists of source systems, which may be R/3 systems, BW systems, flat files, and other systems. In the source systems a SAP component called Plug-In must be installed. It contains extractors. An extractor is a set of ABAP programs, database tables, and other objects that BW uses, which helps to extract data from the SAP systems. This BW Server contain  

 
 Administrator Workbench, Metadata Repository and Metadata Manager, Staging Engine, PSA, ODS and User Roles.

This Administrator Workbench checks metadata and all BW objects. It has two components: one is BW Scheduler and other is BW Monitor. This component helps to load data and to monitor the data.

This Metadata Repository contains information relating to data warehouse. Metadata Repository contains two types one is business-related and other is technical. Metadata Manager is used to maintain Metadata Repository.

PSA (Persistent Staging Area) is also a BW server. This PSA stores data in the original format while being imported from the source system. It ensures quality check of data before they are loaded in their destinations, such as ODS Objects or Info Cubes.


This ODS (Operational Data Store) Objects helps to build a multilayer structure for operational data reporting. It is used for detail reporting.

GUI Design Vs Web Design With Code

 By

Photo: webdevia.com
 
When you go into web design, you'll discover that the face of the field as been forever changed by GUI (Graphical User Interface, pronounced like gooey) design editors. Nonetheless, some designers prefer to work with the underlying page code. Both are part of modern web design courses and have advantages and disadvantages.

GUI programs are familiar to anyone who has used a modern computer, or even a smart phone. Operating systems on computers make themselves user friendly by requiring no knowledge of code. More advanced computer users can still use small snippets of code to check certain details on their computer, but even this is becoming impossible with the latest operating systems.
A similar evolution happened in graphics programs. One of the earliest places where point and click was used to good effect, the first graphics programs actually took number commands to determine line placement. Today that would be absurd and we operate drawing programs with near the same ease of an old fashioned pen and paper, or pain, without having to think about the math behind the picture.

GUI interfaces generally mean that output is based on WYSIWYG (What You See Is What You Get). That means if a table is in a particular place, how it displays on the screen is how it will show up in the final product. This is good enough for a general user, and is a component of basic blogging software, but something a bit more in depth is needed for web design courses.

If you study web design in a computer college, or even if you want to become an expert user, you will learn about HTML (Hyper Text Markup Language), CSS (Cascading Style Sheets) and other coding systems that talk to a web browser to tell it what to display. You might even want to go for some advanced IT training in web based programing and learn to use some of the plug in interfaces. These allow for a number of the in-browser games and utilities the average user makes part of their web experience, from social media through to basics like email and file and photo sharing.
WYSIWYG web design programs usually include a code mode, but you don't even need a fancy program to do it. A simple text editor, with nothing other than basic character input works fine to create HTML. That is how the earliest web designers did it. You'll just view your finished work in your computer's browser, before manually uploading it to your file host. On the other hand, with a WYSIWYG system, it may even do the file uploading for you, as well as allowing you to view the finished product in a variety of browsers, streamlining the design process.

Common Laptop Faults To Look Out For

 By

Photo: cdn3.sbnation.com
 
A laptop computer shouldn't be viewed as unbreakable, you will find there are plenty of issues that might go drastically wrong in day-to-day use, from bumps and scrapes or computer software complications to hardware problems. Having a laptop computer which is frequently carried with you means that anything at all might happen and it may be rather frustrating if issues are encountered. Being familiar with possible laptop errors can help you to self-diagnose complications and from that point figure out the appropriate plan of action to get the issue solved. Here are several of the most common complications where a laptop computer may have to be mended -

Bumps & Knocks

Laptops are designed with mobility at heart, and because of the continual traveling to and fro, they can withstand a substantial amount of punishment. A substantial bump can certainly trigger a laptop computer to fail. Impact damage can damage the external shell or case and even more importantly result in the harddrive malfunctioning. For the case, a couple of good bumps could before long leave the outer shell damaged, warped or dinged up. And, with regards to the inner elements, an unexpected jolt could result in damage to the harddrive or mother board, which can result in the laptop becoming unusable.

Overheating

Quite a frequent issue with laptop computers is getting too hot which generally develops from a fan no longer working efficiently enough. In the event the fan is obstructed, which often can occur when the laptop is put on a soft or textile surface area or blocked with airborne debris, than this might quickly result in the laptop starting to overheat. When the fan isn't capable of working as designed, the interior elements, for example the Central processing unit and hard drive may very well get too hot, which can force the laptop computer to immediately power down - this is usually a built-in, protective measure to prevent long-term harm.

Life Of The Battery

In the event the battery pack isn't in a position to charge then chances are it will be an issue with the exterior power supply or perhaps a defective power jack. The power jack, it is the outlet on the side or rear of the laptop computer which allows you to connect to the AC adapter and it is fairly susceptible to damage because of the frequency of its use. When the AC adapter is often connected and removed, the jack may well come unfastened from the mounting within the mother board, which could result in charging related difficulties.

How to choose between: Netbook vs Laptop

 by:

Photo: techmaza.in
 
 Share of netbooks at PC market has rapidly grown recently. They are more often considered as a future replacement for regular laptops that used to utilize before. However there is an inherent confusion as to what exactly a netbook is and how it compares to a laptop. Undoubtedly both of them have their own advantages and shortages. In order to make your life easier when choosing between 2 gadgets we have listed below points to consider before purchasing:

Size. What you surely feel in the first instance about netbooks is their size. Netbook’s display usually ranges from 7 to 10 inches whereas laptops normally start from 14 inches. This consequently makes netbooks much smaller and lighter comparing to laptops. They are so portable that you may carry them in a purse or small backpack.

Resolution. Most of netbooks currently allow for maximum screen resolution at 1024x600. Anything below doesn’t let you to view whole width of the web page at any one time. So the user has to scroll the page back and forth to read a full line of text. However most recent netbooks are usually produced to allow 1024x600 which is ok for comfortable surfing over majority of web-sites.

Power. The smaller size of netbooks makes them much more power efficient. So you can use a netbook for 5-6 hours without recharging batteries which is about 3 times longer than your average laptop. This feature together with an increased portability puts netbooks in a category of must-have stuff for long distant travellers.

Performance. Of course a size is not the only difference between these 2 categories of gadgets. The main shortage of netbooks relates to their weaker performance specifications. Lower hard drive speed, processor speed and graphics memory apparently do not add any value to the attractiveness of netbooks. Therefore running any sort of processor-intensive jobs like graphics, footage or video modifying wouldn’t be as smooth as it used to be on laptops. Even excessive playing of videos on sites like Youtube can also slow down your netbook considerably. 


Keyboard. Another major complaint about netbooks is the dimension of the keyboards. If you have large fingers, you’ll find that you spend as much time correcting typos as you do typing. Netbooks generally carry scrunched up small keyboards that are rather uncomfortable to type on, making them unsuitable for note taking.

Optical drives and connectivity. Netbooks usually do not have an optical disc drives - so that means no CDs or DVDs. Nonetheless, connectivity is a central focus for netbooks. All of them come with Wi-Fi built in and an increasing number now also have Bluetooth on board, so they can be connected wirelessly to a 3G mobile phone for internet access on the move.

Price. And the last but apparently not least point to consider is the price. Netbooks cost between $200-$500 depending on how fancy you want it and what you are using it for. The cheapest laptops start at around $400. With a low end netbook, you can get on the Internet, type and edit documents, and play some games that don’t need a lot of graphics to run smoothly. The higher end models offer more storage, more RAM, and more features.

Root Bridge for CCNA and CCNP, Part 1

 By

Photo: ccnaanswers.com

As a CCNA / CCNP candidate you are expected to understand the purpose of the Root Bridge and how it is elected.
The first role which the spanning-tree protocol needs to elect is which switch device on your LAN will act as the Root Bridge, or as I like to refer to it "The reference point."

Each spanning-tree protocol enabled switch will commence the election of the reference point by issuing out of all live ports a frame called a BPDU (Bridge Protocol Data Unit), within this frame are details regarding the transmitting switches spanning-tree credentials that are used to determine if it will be the reference point.
When a switch receives a Bridge Protocol Data Unit it will compare the contents with it's own values to determine if the received values are better than it's own. The first value which the switch will look at will be a value called the "Default Priority", by default this value is set to 32768, which ever switch advertises the lowest Default Priority will be elected the Reference Point (Root Bridge), if on the other hand the Default Priorities are the same the lowest switch MAC address is used to break the tie.
Note: The Default Priority and MAC values are carried within the BPDU.
Once the Reference Point (Root Bridge) has been determined the switches will now need to choose which of their ports will need to block and which can remain open.

The best way to understand how they choose which ports should stay open and which block is to picture two switches connected together via one link, port 1 on switch 1 to port 1 on switch 2. For our example we will imagine switch 1 being the Root Bridge.

As Switch 1 is the Root Bridge and as such will issue BPDU's claiming to be so out of the only port is has connected, switch 2 receives the BPDU on a single port and no other port, since switch 2 can only see the root bridge on a single port it will keep that on open and not block any other port since it cannot see the BPDU on any other port.

If you now connect the two switches together via their respective Port 2 switch 2 will start receiving BPDU's down both port 1 and port 2, in this scenario switch 2 has to block one of the ports but which one?

Replacing Laptop Parts Made Simple

 By

Photo:  howitoo.com

There might be a minor problem in your laptop and replacing the current model is simply not an option. In this case, get the replacement part and save money. Minor issues come about this is why replacement parts such as bulbs, screen, power button boards, laptop LCD cables, keyboards and many other parts can be found easily online. The battery life is the one such crucial part.

Steps to extend battery life are as follows:

• Mute or turn down the volume if it is not required
• Remove external devices such as USB devices, Bluetooth and Wi-Fi
• Change the display setting by dimming the light option
• Clean battery contacts to increase the energy efficiency
• Hibernate rather than selecting the standby option

Compaq laptops offer good performance at affordable prices. There is a range available for students, business people and also homeowners. Remember to know what features you personally require before purchasing one. You can easily find replacement Compaq laptop parts online.
Many people replace their notebook screens as well. Why do people replace their screens? This is because the clarity and brightness are not as it used to be. People usually upgrade to a higher resolution by ordering a new LCD screen. Bring your notebook back to life by replacing the damaged screen. Search online and find the best LCD screens for notebooks of Sony, Toshiba, Apple, Acer and many other brands.

All of the sudden one fine day you switch on the notebook, but your screen is dark and dim. This is generally because the LCD inverter needs to be replaced. It is easy to replace a faulty screen rather than replacing the entire screen. LCD inverters come in different sizes like 12", 14", 15.4" and 17". It is this inverter that is the power source for the backlight of your laptop.

A laptop adapter is vital for charging the batteries of your device. An adapter can stop working due to many reasons. The main reasons include damaged AC jack, faulty motherboard, etc. Every brand has a different adapter specifically designed for that device. It's imperative to know the brand and series number before purchasing an adapter.

Keyboards are not as expensive as other parts might be. After a certain time, the buttons on a keyboard don't work as smoothly as they should. Thanks to the internet replacing and buying new parts has become simpler and saves us from the hassle of visiting stores.

The Illusion of Business Intelligence

by:

Photo: res.sys-con.com
 
The proponents of BI however hope to fulfill the vision of Laplace; who suggested: '... with an intelligence sufficiently vast to submit all comprehensable data to analysis ... nothing would be uncertain and the future and past present to his eyes.' 

Business Intelligence is not a productive system, such as accounting, stockkeeping, or supply chain management. Customer care or relationship management should first be consodered as a tool to manage and track your customer service, but is often seen as an analysis tool for customer behavior to improve for example cross-selling rather than service quality.

Business Intelligence is complex and expensive software for gathering and analyzing masses of data that supposedly will be of help to make better business decisions. It relies on a faith in mathematics that were obtained by Bernoulli, Coombs, Edwards, Neumann and Morgenstern. They saw heuristic approaches to decision making as defective because it takes resource saving short-cuts.

The proponents of BI now claim that it provides the computing power to optimize decision making by calculating probability for maximum utitlity, as described by Simon (1955). Optimisation however, relies on a number of restrictive assumptions, such as that the process of decision analysis has to be followed precisely and that the data available are correct and relevant. Let's for a moment assume that the garbage-in problem has been solved and the data given to the business executives are good.

Klein (1999) provides a list of these restrictions and requirements that were identified in many studies :

1. The goals must be well defined in quantitative terms.

2. The decision makers values must be stable.

3. The situation must be stable.

4. The task is restricted to the selection of options.

5. Exhaustive generation of alternatives.

6. Optimal choice must be possible in reasonable time.

7. Thorough comparison of options.

8. Use compensatory strategy

9. Probaility estimates must be coherent and accurate.

10. Failure prediction must be exhaustive.

11. Evaluation must be exhaustive

There are many studies about human decision making and most of them come to the conclusion that 'less is more'. Less information about a subject makes for better decisions. Bi can be used to gather and consolidate information that then seems to be simpler and easier to use for decisions. The problem is one of comprehension and trust. Can the user comprehend what the data values truly mean? Do the metadata make sense to the deciding person? Can past averages, means, standard deviations and periodic data be used to predict the future? I propose that just a few people within any organization might even sensibly comprehend what those data could mean. The old adage of garbage-in-garbage-out still holds. Who knows if the mathematical methods used to process the data are well chosen.

Klein (1999) proposes that forcing people to give up their heuristic approach to decision making puts them into 'information overload' and questions optimization as the gold standard for decision making.

Now that users of Business Intelligence data do not find them too helpful and seem overwhelmed, the new idea is to aid or replace human decision making with predictive analytics, using probability calculated from past data. Probability computing about future events is the next illusion that BI proponents sell.

Here is a list of what the executives and managers really need for decision making and don't get from Business Inteligence:

- what customers want.

- what to do to be competitive.

- where business has to innovate.

- how the market will react to current and upcoming changes.

- what competitors are currently doing.

- how employees really see the company.

- how to impove the profitability of the business.

- how to improve internal communications.

- the quality of business processes (not the quality of execution).

You might recognize a common element in the above list: Knowledge is not about knowing a lot of data, or taking decisions based on data. One has to come up with an ACTION or a list of alternative actions and then take a decision which one to perform. Finding out from BI that revenue is dropping only says that the management is out of touch with the business.


Simon (1972) was concerned that optimization was not practical in a field setting because of its restrictions. I propose that there is no proof available that BI solves the problem of the restrictions listed above. Business Intelligence can enforce the optimization process for the decision maker and seemingly create the conditions necessary. It can however only propose options based on the data available to the system. It can not propose to the user to go outside the system and analyze other information as it brakes the optimization process. As a consequence it BLINDS the decision maker to the real world. Klein (1999) proposes that it the enforced optimization process stops the decision maker from gaining experience for future benefit. Outside opportunities and constraints would be totally ignored.

Business Intellilgence enforces a better decision making process but not a better quality of decision making.

Timely and good quality information is not like having a crystal ball. It is abstract information and will tell the user nothing that he doesn't know. We can only make decisions based on analogies to previously perceived patterns that have to be fairly simple. Statistical software does not take better decisions just because it can process more data. Any data given to the user that is not truly relevant turns into noise that reduces the quality of the communication channel and obfuscates the important information. Less data means less noise.

What information should it be that truly represents a company's competitive position in the market? Past sales data and comparisons of market share? What decision will that offer? The best way to find out about the competion is to ask a customer who decided for another product why. A competitor is a friend who helps the business to improve what it does. Without competitors companies would become complacent. Inteviewing five of those customers who switched - ideally face to face - will provide much more decision making input than statistics. That certain groups of randomly classified people spent a certain amount on randomly classified goods is not knowledge. A qualified manager who attends sales calls or walks into the store to speak with customers will see those changes in customer behaviour in real-time. He can ask about customer preferences at the time they happen and not months later in a filtered and watered down manner that is completely abstract.

March (1978) and Simon (1983) propose that people do not decide by calculating expected utility and question its mathematical foundation (that is used in BI) for real-world situations. Klein (1999) proposes that training people by exposing them to experience of decision making is more important than abstract optimization processes. This falls in line with Thomas Sowell in 'Knowledge and Decisions' who calculates the cost of knowledge by its practical usefullness and not by the amount of abstract eductation.

Antonio Damasio (1995) has virtually proven the influence of our emotional center on human decision making and Steven Johnson paints a wonderful picture of the power of our human mind in its connection of instincts, intuitions and emotions created by the link between the neocortex and hippocampus, and amygdala. Good decisions come from feeling good about a decision and mathematical optimization strategies fail to do that.

Massive business intelligence data do not eliminate the guesswork but create a substantial amount of new guesses that have no connection with the real world situation. Yes, gather business relevant data, filter it and link just the neceassary detail right into your business service, that will improve decision making. Our uncertainty is not reduced by knowing more, as we all have experienced. That is the approach we propose at ISIS Papyrus Software.

Top Tips for Buying a New Computer

 By

Photo: techlocation.com
 
So you want to buy a new computer? Maybe this is your first computer or maybe it's an upgrade from an old relic you've had for a while. Whatever the reason for the new computer, this article will help you make some key decisions around what to look for in your new computer.

1. Desktop or Laptop? This is always a huge question and there are whole articles discussing just this very thing. For me it comes down to one question: Does it need to be portable? Laptops are great for people on the move. They are awesome if you don't have a lot of space to put a big desktop computer. But they are disposable. They are hard to repair and expensive if you decide to repair them. They aren't upgradeable either. The desktop computer will last you longer, you can upgrade it and if it does break, the part is easily replaced. Make this decision based on your own needs and preferences.

2. What am I going to use it for? You need a lot more power to play online games such as World of Warcraft than you do to write a letter in Microsoft Word. Decide what you will use it for first and then pick a computer that fits that need. Remember that they make computers specifically for gaming. They are high powered computers with expensive video and sound cards and a lot of processing power. You don't need all that to check the news your standard desktop computer will do just fine.

3. How much money do I have to spend? This determines everything! You can get a desktop computer for $300 if you want. These are perfectly good computers. They probably won't play your online role playing game, but they are good for surfing the web and doing some word processing. On the other extreme you can spend $2000, $3000 or even $5000 on a brand new system that does everything and will play any game you throw at it. So decide whether you're getting a laptop or a desktop and what your intended usage is and then pick a budget that fits your needs.

4. How do I pick once I've narrowed down my choices?
a. Look at processing power first. We are up to iCore7 and counting. You may not need an iCore7 for your purposes now, but if you can afford a little extra juice it will help extend the life of your computer.

b. Then look at the amount of RAM you need. I suggest no less than 4 GB of RAM. Make sure the computer will handle at least 6 or 8 GB though. This gives you some upgrade room when you need it.
c. Now decide how much storage you need. Most computers come with at least 200 or 300 GB now and many with much more than that. Storage space is easy to expand as needed with external hard drives and USB thumb drives so it's not a crisis if your hard drive is a little small.

d. Lastly look at the extras like DVD burners, a fancy mouse or keyboard, video cards and sound cards. Unless you're watching a lot of movies or listening to a lot of music or playing those games we talked about, the video card and sound card that are in the computer will be fine. Often these are referred to as "onboard video" or "onboard sound." All that means is that they are part of the motherboard, not an extra card like you can buy at any computer store.

When you finally decide on a computer make sure you have all of the cables you need to hook up your monitor and printer if you have one. Keep the receipt in case it doesn't work for some reason or you're missing pieces and make sure you keep the box for a while. Often the box is your warranty. Many manufacturers require you to send the computer back in the original box for repair if it's needed. Once the warranty period ends you can throw out the box.

Print this article in case you need it and have fun shopping! Buying a new computer is a lot of fun once you learn a little bit about what you're buying and what you need. Getting the right computer for your needs takes a little research, but it's worth the effort. When you get a computer that can keep up to your needs it makes your life a lot easier. Enjoy!

Challenges in Distributed Java Applications

By

Photo: res.sys-con.com
 
Different type of software applications are incorporated at each level of the industry as well as in individual practices so as to facilitate their technology related tasks and operations. Various development technologies and concepts are introduced to make the process of development easier and to make software more innovative and effective. Different development technologies and platforms are chosen according to the scope of the application.
Java is one of the important programming languages used by the software application developers since they can be deployed on any hardware platform without the need to modify the code. The reason of such sophistication is compilation of code at the bit-level i.e. Java code is first compiled into a binary file and so is executable at all platforms. This also makes Java a suitable platform for deploying over a distributed environment, where systems are located over the network with different hardware configurations and platforms.
Java has been a mainstream programming language for over a few decades due to its infinite usability for developing software. However, for deploying it in a distributed environment, the following issues and challenges can be encountered:
  • Efficient Memory Management: All the memory management tasks are undertaken by the Virtual Machine or JVMs hosting the component of applications. So even after developing an efficient application to work in a distributed environment, developers cannot precisely estimate how the memory is managed on the remote machine. This becomes a challenge when some nodes over the network are performing poor in terms of memory allocation and release.

  • Performance: Common bottlenecks related to the performance of application in conventional language like C, are easy to identify. However in case of Java, deployed in a distributed application, identification of the performance issues is difficult and moreover, a distributed environment appends the additional overhead in the performance of the code because of the execution model of Java. Native applications, on the other hand, serve the purpose in a more productive way making deployment on the Java platform a concern for developing distributed applications.

  • Reliability: "Threads" provide a crucial advantage for developing multi-tasking software in Java. However, in distributed software, excess use of threads increases the chances of problems like resource contention or dead-lock. These problems, if taken place, can freeze a system and cause serious performance related issues and run-time errors. It requires the component-level assessment of code for proper functionality to speculate any kind of run-time error.
Testing of the components in distributed application is difficult as various components reside on systems and need to be tested simultaneously. In order to optimize the performance and reliability of the application, developers need to deploy various tools and assisting software to enhance the quality of the software which should be efficient as well as productive with minimum error-prone areas.
