			<content:encoded><![CDATA[<p>Here I have shortlisted applications (including web-based apps), based on years of sieving and experimentation. You’ll find many of them very handy. The amazing thing is – they are all freeware!<span id="more-1545"></span></p>
<p><strong>E-mail</strong>: Gmail. Not exactly a software since it’s web mail, but its hands down the best email managing system IMO. (and I’ve used other email clients before like Outlook, Lotus, Yahoo).</p>
<p><strong>Browser</strong>: Google Chrome. I switched from Firefox last year. It took some getting used to in the first week. But after that, I started loving Chrome. I love that it lets you shift your tabs around, unlike Firefox. It also lets you “pin” your frequently accessed pages so it becomes a small icon on the navigation. It’s fast, minimalistic in interface, and very reliable as a browser.</p>
<p><strong>Calendar</strong>: GCal. Keeps all my schedules in check, and it’s web-based so you can access it anywhere – even your phone if it has the web-surfing function</p>
<p><strong>Task Shuffler</strong>: Ever felt the need to move the programs around in your task bar? I know I do. This is an extremely handy program that allows you to do just that, simply via clicking/dragging/dropping. For Windows only.</p>
<p><strong>Screen Capture</strong>: Snipping Tool if you are using Windows Vista (in built), Zap Grab if you are using other platforms. Just click and grab any part of the screen, and you have your image. Extremely useful.</p>
<p><strong>Automated Computer Shut Down</strong>: Switch Off. Automatically Shuts down/ Hibernates/ Restarts/ Logs Off your computer at a time you input. Great if you are downloading something which is taking a while but you need to leave your computer before it finishes.</p>
<p><strong>Audio</strong>: Audacity. Free, open source software for recording and editing sounds.</p>
<p><strong>Document Processor</strong>: Libre Office. This is almost a direct clone of MS Office set (Powerpoint, Word, Excel) – about 99.9% similar. I find it hard to believe that this is free! The only issue I’ve experienced so far is the slight change in formatting when you convert to MS office extensions (.doc, .xls) – but it’s manageable.</p>
<p><strong>PDF</strong>: PDF Creator. Libre Office already comes with an inbuilt pdf creator. But if you want to create PDFs from other applications, PDF creator is for you. As long as there’s a “Print” option, you can generate a pdf from there.</p>
<p><strong>Graphics Editing</strong>: GIMP. Very similar to Adobe Photoshop. Some functions are named and organized differently than Photoshop, so if you are a Photoshop user you can download GIMP Shop to change GIMP’s interface similar to Photoshop. The amazing thing is how GIMP packs with so much graphic editing prowess in such a small program (installer is 15.2meg, while Photoshop is over 700meg).</p>
<p><strong>FTP</strong>: Filezilla. Excellent FTP program that does its job well. You got to love open source projects.</p>
<p><strong>Chat</strong>: GTalk. Extremely low-resource and fast chat application with functions that supersede MSN (example: logging of chat history which is integrated with and automatically saved in Gmail Chat folder). For even more functions (emoticons, group chat, etc), check out Gtalk Labs Edition.</p>
<p><strong>Blogging</strong>: WordPress.org if you are looking to host your own blog and WordPress.com for the free hosted version. Personal Excellence is using WordPress.</p>
<p><strong>Journal</strong>: Daily Diary. A very simple yet effective free journaling application that lets you type and store your entries on your computer. Comes with password protection and multiple journal creation for different purposes (e.g., record of different goals, areas of your life, etc)</p>
<p><strong>Video player</strong>: VLC Media Player. The best multi-format media player. With so many different media formats out there, this one is a catch-all player that plays almost anything. And it’s resource light too.</p>
<p><strong>Information Storage</strong>: Ever Note. Storage central for information captured across any environment – Computer, Web, Phone.</p>
<p><strong>To-Do Lists</strong>: Remember The Milk. Very effective for getting your tasks in check. It’s web-based, which means you can access it anywhere.</p>
<p><strong>Post-It Notes</strong>: Morun Sticky Notes. Minimalistic post-it notes on your desktop. Convenient placeholder for storing commonly-accessed or used information.</p>
<p><strong>Mind Mapping</strong>: Free Mind. It’s a great open-source mindmapping software. Great tool and very user-friendly.</p>
<p><strong>Timer</strong>: E.gg Timer. This is a web-based app and not an actual software. It’s an online stopwatch you can time yourself and it’ll beep at the end. Very useful if you want to timebox when doing a task, exercising, etc.</p>
<p><strong>Internet Calls</strong>: Skype. Gtalk works great too as a backup. Both support video conferencing.</p>
<p><strong>HTML Editor</strong>: NVU is a free, open source web editor, which you can use to build your website via a WYSIWYG editor (what-you-see-is-what-you-get). According to the website, it rivals programs as Adobe’s Dreamweaver and Microsoft’s Expression Web even, in functionality. Usually I use notepad for webpage edits outside of the WordPress platform, but when there’s heavy coding involved, NVU is a great time saver. I used it to build the PEBook and 30DLBL</p>

			<content:encoded><![CDATA[<p>Ahmed M. Rahman</p>
<p>Many people today have flown in an airplane. It is a common communication network today. To travel long distance airplane is must. Many ask the simple question &#8220;what makes an airplane fly&#8221;? The answer one frequently gets is <span id="more-1543"></span>misleading and often just plain wrong. We hope that the answers provided here will clarify many misconceptions. We are going to show you that lift is easier to understand if one starts with Newton rather than Bernoulli. We will also show you that the popular explanation that most of us were taught is misleading at best and that lift is due to the wing diverting air down.</p>
<p>For an airplane to fly, it must always engage in a tug of war between the opposing forces of <strong>lift versus weight</strong><strong> </strong>and <strong>thrust versus drag</strong>.  For a moment, think of an airplane moving from right to left and the flow of air moving from left to right.<strong> </strong><strong>The weight or force due to gravity</strong><strong> </strong>pulls down on the plane opposing the <strong>lift</strong> created by air flowing over the wing. <strong>Thrust</strong> is generated by the <a href="http://www.allstar.fiu.edu/aero/proptypes.htm">propeller</a> and opposes <strong>drag</strong> caused by air resistance to the airplane.  During take off, thrust must be greater than drag and lift must be greater than weight so that the airplane can become airborne. For landing thrust must be less than drag, and lift must be less than weight.</p>
<p>An airplane in flight is the center of a continuous tug of war between <strong>four</strong><strong> </strong><strong>forces</strong><strong>: </strong><strong>lift</strong><strong>, </strong><strong>gravity force or weight</strong><strong>, </strong><strong>thrust</strong><strong>, </strong>and<strong> </strong><strong>drag</strong><strong>. </strong><strong>Lift and Drag are considered aerodynamic forces because they exist due to the movement of the aircraft through the air</strong>.  The weight pulls down on the plane opposing the lift created by air flowing over the wing. Thrust is generated by the propeller and opposes drag caused by air resistance to the frontal area of the airplane. During take off, thrust must overcome drag and lift must overcome the weight before the airplane can become airborne. In level flight at constant speed, thrust exactly equals drag and lift exactly equals the weight or gravity force. For landings thrust must be reduced below the level of drag and lift below the level of the gravity force or weight.</p>
<p>Lift: Lift is produced by a lower pressure created on the upper surface of an airplane&#8217;s wing compared to the pressure on the wing&#8217;s lower surface, causing the wing to be &#8220;lifted&#8221; upward. The special shape of the airplane wing (<strong>airfoil</strong>) is designed so that air flowing over it will have to travel a greater distance faster, resulting in a lower pressure area (see illustration) thus lifting the wing upward. Lift is that force which opposes the force of gravity (or weight).</p>
<p>Many believe that this explanation is incorrect because flat wings (such as seen on balsa wood airplanes, paper planes and others) also have managed to create lift.   Please read <a href="http://www.allstar.fiu.edu/aero/airflylvl3.htm">How planes fly:  the physical description of flight</a> as well to get a fuller understanding of the creation of lift.  It is more advanced, though.</p>
<p>Thrust: Thrust is a force created by a power source which gives an airplane forward motion. It can either &#8220;pull&#8221; or &#8220;push&#8221; an airplane forward. Thrust is that force which overcomes drag. Conventional airplanes utilize engines as well as <a href="http://www.allstar.fiu.edu/aero/proptypes.htm">propellers</a> to obtain thrust.</p>
<p>Drag : Drag is the force which delays or slows the forward movement of an airplane through the air when the airflow direction is opposite to the direction of motion of the airplane. It is the friction of the air as it meets and passes over and about an airplane and its components. The more surface area exposed to rushing air, the greater the drag. An airplane&#8217;s streamlined shape helps it pass through the air more easily.</p>

			<content:encoded><![CDATA[<p>Ahmed M. Rahman</p>
<p>An Air conditioner is a common electronic device. It used offices and home in everywhere, especially in the tropical region. An air conditioner (often referred to as AC) is a home appliance, system, or mechanism designed to dehumidify and extract heat from an area. The cooling is done using a simple refrigeration cycle. In construction, a complete system of heating, <span id="more-1523"></span>ventilation and air conditioning is referred to as &#8220;HVAC&#8221;.In 1758, Benjamin Franklin and John Hadley, professor of chemistry at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids such as alcohol and ether could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to &#8220;quicken&#8221; the evaporation; they lowered the temperature of the thermometer bulb to -14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). In 1820, British scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate.<br />
Air conditioners employ the same operating principles and basic components as your home refrigerator. Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings of your home; likewise, an air conditioner uses energy to transfer heat from the interior of your home to the relatively warm outside environment.<br />
An air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.<br />
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils.<br />
The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling your home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser&#8217;s metal tubing and fins.<br />
Throughout the second half of the 20th century, nearly all air conditioners used chlorofluorocarbons (CFCs) as their refrigerant, but because these chemicals are damaging to Earth&#8217;s ozone layer, CFC production stopped in the United States in 1995. Nearly all air conditioning systems now employ halogenated chlorofluorocarbons (HCFCs) as a refrigerant, but these are also being gradually phased out, with most production and importing stopped by 2020 and all production and importing stopped by 2030.<br />
Production and importing of today&#8217;s main refrigerant for home air conditioners, HCFC-22 (also called R-22), has begin to be phased out in 2010 and will stop entirely by 2020. However, HCFC-22 is expected to be available for many years as it is recovered from old systems that are taken out of service.</p>

			<content:encoded><![CDATA[<p>System Center Configuration Manager 2012<br />
In a former life, SCCM was known as Systems Management Server (SMS). With the upcoming release of SCCM 2012, Microsoft is introducing major changes to the product designed to enhance the end-user experience and streamline IT operations.<span id="more-1514"></span><br />
For example, in SCCM 2012, Microsoft is making the user the focus rather than computers. This really makes sense, particularly as users begin to rely on more and more devices. With SCCM 2012, as users roam between different computers, their applications can follow them.<br />
To this end, Microsoft is also adding a better software portal to SCCM 2012. While SCCM has always had a concept of a portal, it wasn’t very intuitive. With SCCM 2012, the software portal is a Web-based service from which users can proactively choose to install new software.<br />
The big deal: These features are just the tip of the iceberg when it comes to what’s new and good in SCCM 2012, but they demonstrate Microsoft’s focus on the end user, which, along with initiatives such as BYOD and even VDI, are the continuation of a trend in this direction.</p>
<p>System Center Operations Manager 2012<br />
For quite a while, SCOM has had availability monitoring for network devices, and there have been third-party tools that could get more detailed information from network devices. However, SCOM 2012 provides support for much more in the way of native device monitoring. SCOM 2012 offers the ability to discover and monitor network devices, including the various interfaces and ports on those devices. With SCOM 2012, you can go far beyond simple up/down monitoring in SCOM.<br />
The big deal: Microsoft offers various System Center bundles that make the products available in affordable ways. Now, SCOM can be used for much more than it could before. SCOM has always been an outstanding monitoring tool for Microsoft environments. SCOM 2007 added support for some third-party platforms, and SCOM 2012 extends the infrastructure monitoring capabilities of the product.</p>
<p>Windows 8 client<br />
Much has been written about Windows 8, and Microsoft is certainly making the product an emphasis in the coming form factor war. If Windows 8 works the way that Microsoft seems to want it to work — and the market accepts it as a viable option outside the confines of the traditional computing space — the product could revolutionize computing by allowing the same operating system and applications to run seamlessly across a wide variety of devices, including PCs, laptops, tablets, phones, and even gaming consoles. Obviously, Microsoft has Windows Phone 7 as another mobile option for mobile devices, but the interface similarities may help when it comes to widespread adoption.<br />
The big deal: It’s clear that Microsoft has an uphill battle ahead of it when it comes to the mobile space. If the company can get Windows 8 right, it could create massive opportunities for developers to get their applications in front of audiences on any device form factor they use.</p>
<p>Lync<br />
I like Lync. The product has the potential to seriously disrupt the telephony space, and it adds serious unified communications capabilities to organizations that deploy it. Lync 2010 added a number of user-centric features, including the “me” area, which allows users to set their own status and track their own visibility. Lync also enables users to share individual desktops and to collaborate with other users. In addition, Lync includes audio and video conferencing capabilities and much more.<br />
The big deal: Between Lync and Microsoft’s Skype acquisition, the company is well positioned to own the voice and video space if it can execute well. Lync can be a full-fledged replacement for an existing PBX and makes person-to-person communication very easy via a number of different channels.</p>
<p>Hyper-V 3.0<br />
Microsoft has gone on record to say that Hyper-V 3.0 will catapult the company’s virtualization efforts and move it, in some ways, beyond what even VMware is offering. Hyper-V 3.0 will add the ability to perform multiple concurrent live migrations and introduces the new VHDX virtual disk format, a virtual fibre channel adapter and boot from SAN capabilities.<br />
From a scalability perspective, Hyper-V 3.0 supports up to 160 logical processors on a host, as well as up to 2 TB of RAM. Guests will be able to support 32 vCPUs and up to 512 GB of RAM.<br />
The big deal: Again, this is not intended to be a complete Hyper-V 3.0 primer. However, this is another instance where a combination of circumstance and feature gap closing may help Microsoft. VMware has, in the opinion of many, made some serious errors in its new licensing schemes. This may provide an outstanding opportunity for Hyper-V 3.0 to begin to supplant VMware in some environments. Hyper-V 3.0 will begin to erase some of VMware’s feature lead, which may help this process along.</p>

			<content:encoded><![CDATA[<p>Microsoft showed us a more in-depth look at Windows 8 today, from the previously mentioned tablet interface to the traditional mouse-and-keyboard desktop. Here&#8217;s what it looks like.</p>
<p>Microsoft&#8217;s &#8220;re-imagining&#8221; of Windows 8 is focused very heavily on a new, Metro-style touch-based interface. However, they make a big deal of saying that it&#8217;s just as usable with a mouse and keyboard—and no matter what device you&#8217;re on, you can switch between the simple Metro interface and the traditional Windows desktop to fit whatever your needs are at that given moment.<span id="more-1450"></span></p>
<p><strong>Performance Increases</strong></p>
<p>One of the issues that&#8217;s been on our minds since they previewed this new interface was whether this will keep bogging Windows down with more running processes, and whether running a full Windows desktop on a low-powered tablet was really a good idea.</p>
<p>Performance was the first thing they addressed today: Windows 8 actually has better performance than Windows 7, even with this metro interface running on top of a desktop. Tablet users and netbook users should notice a fairly significant performance increase with Windows 8. What it really &#8220;feels&#8221; like in real-world usage remains to be seen, but you can see a comparison between a task manager running on both operating systems above—which makes us pretty hopeful. Furthermore, any of your tablet-based apps will suspend themselves when you jump into the traditional desktop, so they don&#8217;t take up any of your resources.</p>
<p><strong>The Lock Screen</strong></p>
<p>Windows 8&#8242;s lock screen is pretty much what you&#8217;d expect: it&#8217;s got a beautiful picture along with a few little widgets full of information, like the time, how many emails you have, and so on. However, after swiping to unlock, Windows 8 shows off some pretty neat touch-based features, particularly a &#8220;picture password&#8221; feature. Instead of using a PIN or a lock pattern to get into your system, you swipe invisible gestures using a picture to orient yourself (in the example they showed, the password was to tap on a person’s nose and swipe left across their arm). Android modders might find this similar to CyanogenMod&#8217;s lock screen gestures.</p>
<p><strong>The Home Screen</strong></p>
<p>The home screen is very familiar to anyone who&#8217;s used Windows Phone 7. You&#8217;ve got a set of tiles, each of which represents an application, and many of which show information and notifications that correspond to the app. For example, your email tile will tell you how many unread emails you have (and who they&#8217;re from), your calendar tile will show upcoming events, your music tile will show you what&#8217;s playing, and so on. You can also create tiles for games, contacts, and even traditional Windows apps that will pull you into the Windows desktop. The tablet-optimized apps are all full screen and &#8220;immersive&#8221;, though, and you can rearrange their icons on the home screen easily (just as you would on any other tablet platform).</p>
<p><strong>Running Apps</strong></p>
<p>Running a basic app works as you expect—you tap on its home screen icon and it goes full screen. The browser has lots of touch-based controls, like pinch to zoom and copy and paste, and apps can also share information one another easily. To do so, you just need to select text in the browser or choose a photo in their cloud-based photo app and hit the &#8220;Share&#8221; button—you&#8217;ll then be able to pick an app to which you want to send that text or picture, and work with it from there. For example, you can share photos to Facebook, send text from a web page in an email, and so on.</p>
<p>None of this is brand new to touch-based platforms, but what is new is the ability to not only multitask, but run these apps side by side. Say you want to watch a video and keep an eye on your news feed at the same time. Just like in Windows 7 for the desktop, you can dock an app to one side of the screen while docking another app at the opposite side, which is a seriously cool feature. Imagine being able to IM and play a game at the same time, or browse the web while writing an email. It&#8217;s a fantastic way to fix one of the big shortcomings of mobile OSes, thus allowing you to ignore the full desktop interface more often and stay in the touch-friendly, tablet view.</p>
<p><strong>The App Store</strong></p>
<p>The Windows App Store looks much like the home screen, with tiles that correspond to different categories and featured apps. From there, you can look at a more detailed list of the available apps in a given section. And, the store contains not only touch-based apps for the tablet interface, but some of the more traditional desktop Windows apps you&#8217;re used to, so you have one portal to discover all your Windows apps no matter what interface you&#8217;re using.</p>
<p><strong>Windows Live&#8217;s Cloud Syncing</strong></p>
<p>Windows Live is taking center stage as the backend for all of Windows 8&#8242;s cloud syncing abilities. Your address book, photos, SkyDrive data, and even data within third-party apps can sync up to the cloud with Windows Live. The address book also syncs with other services like Facebook and Twitter as well. You can even sync all of your settings from one Windows 8 PC to another. Just sign onto your Windows 8 with a Windows Live ID and you&#8217;ll get all your themes, languages, app settings, taskbar, and other preferences will show right up. It&#8217;s a pretty neat feature if you have multiple Windows 8 PCs and don&#8217;t want to set them all up separately—just a few taps and you&#8217;ve got all your preferences ready to go.</p>
<p><strong>A New Task Manager</strong></p>
<p>Microsoft&#8217;s finally redesigned the task manager, and it looks pretty great. You have a very simple task manager for basic task killing, but if you&#8217;re a more advanced user, you can bring up the detailed task manager filled with information on CPU and RAM usage, Metro app history, and even startup tweaking—so you can get rid of apps that launch on startup without going all the way into msconfig.</p>
<p><strong>Windows Explorer</strong></p>
<p>You will have native ISO mounting in Windows Explorer, a new Office-style ribbon, and a one folder up button like the old days of XP. It also has a really cool &#8220;quick access&#8221; toolbar in the left-hand corner of the title bar that gives you super quick access to your favorite buttons from the ribbon.</p>
<p><strong>Other Features</strong></p>
<p>Along with these cool features, Windows 8 also comes with other features. It&#8217;s got system-wide spellchecking, so you don&#8217;t have to rely on a specific app to keep your writing top-notch, as well as a system-wide search feature, that lets you search anything from your music library to your contacts to the web itself. It also has a really cool feature for desktop users that lets your run the Metro UI on one monitor while running the traditional desktop on the other.</p>
<p>It also has a really cool feature called &#8220;refresh your PC&#8221;, where you can do a clean install with the tap of a button. Whether you&#8217;re selling your machine or just want a cleaner, faster installation of Windows, you can do it all in one click. You can even set refresh points, similar to restore points, so you can refresh your PC to the way it was at a certain point in time.</p>

			<content:encoded><![CDATA[<p>As companies turn to social media giants like Facebook and Twitter to drive traffic and gain new customers, there is a growing risk that the website — one of the most powerful sales and marketing tools — will be overlooked. <span id="more-1382"></span></p>
<p style="text-align: justify;">It is important for every consumer-facing enterprise to seek out new prospects and drive additional traffic via all available social media channels. Yet too many companies still neglect some basic strategies that could maximize conversion rates for the traffic they already have. The following strategies — when implemented correctly — will not only lead to an increase in conversion rates and revenue from mobile and social media channels but will also help drive companies toward an important cultural transformation, one that can elevate them above competitors and help them stay there.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>Some Perspective</strong></p>
<p style="text-align: justify;">Commerce is becoming less about channels and more about touch points. Marketing is moving beyond multichannel to become “multipoint,” and coping with this shift is a serious challenge for businesses of all kinds.</p>
<p style="text-align: justify;">Fortunately, the website remains a place where many customer conversations are initiated, and a growing percentage of transactions are completed, even if they begin elsewhere. A strong yet nimble website — one that can efficiently leverage customer data — will put brands in a better position to effectively respond to the emerging demands of multipoint marketing. Without such a site, they will continue to lose out on potential revenue and lose ground to more agile competitors.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>1. Understand Your Customer</strong></p>
<p style="text-align: justify;">By tracking anonymous consumer behavior on the website, companies can display campaigns, content, offers and experiences tailored to an individual’s browsing habits. Watch what they search for and what they look at, not just what they buy.</p>
<p style="text-align: justify;">For example, you might display the latest Air Jordans to consumers who have a history of browsing Nike sneakers. In my experience, retailers who target promotions based on brand preferences see a double digit increase in average order value.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>2. Make Webpages Relevant</strong></p>
<p style="text-align: justify;">Websites should adjust marketing content in real time to reflect current events or other sales-related factors, such as customer location. Content that is tailored to different key segments (for example, notifying overseas consumers of discounted international shipping or letting customers from Florida know there’s no sales tax) can help persuade them to purchase.</p>
<p style="text-align: justify;">Relevance includes adjusting site content to reflect where a consumer comes from. For example, were they directed from Facebook or an email newsletter? Make sure the messaging that brought them to the site is reflected in the site experience and inform that site experience with what analytics show about that traffic segment. For example, data may indicate that the buying habits of customers from Facebook are different from those who land on your site via email.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>3. Use Offline Learning to Inform Online Action</strong></p>
<p style="text-align: justify;">Many multichannel retailers have accumulated a lot of knowledge about their customers. For example, managers of brick and mortar stores know that there are local brand preferences. Headquarters may track brand preference by region or state. So use that data to geo-target online traffic.</p>
<p style="text-align: justify;">If Texas shoppers prefer Wranglers to Levis, highlight Wranglers to online traffic from Texas. The results will be improved conversion rates and higher average order values.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>4. Consistency Is Key</strong></p>
<p style="text-align: justify;">Traffic that comes from outside channels like social media will convert better if consistent messaging is maintained throughout the sales cycle. A promotion that initially drives traffic to a website (such as “Twitter followers receive 20% off”) should be reflected not just on the landing page but also on each page that the visitor sees until they check out.</p>
<p style="text-align: justify;">This doesn’t mean a site makeover. Instead, the message simply needs to echo the messaging that caught the consumer’s attention in the first place.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>5. Test, Test, Test</strong></p>
<p style="text-align: justify;">To know if a site is truly compelling, brands must constantly test it to ensure that content is presented in a manner that resonates with consumers to produce optimum results. Businesses should test for sticking points and optimize the choice of messaging, design of buttons, layout of forms and display of positive reinforcements like trust seals and privacy assurances. Even a small improvement at each stage of the process will pay big dividends.</p>
<p style="text-align: justify;">Smart marketers will establish a culture of testing. By making the use of A/B and multivariate testing tools, brands can increase creativity, experimentation and revenue. A culture of testing in which decisions are data-driven is the best posture from which to meet marketing challenges.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>Looking Forward</strong></p>
<p style="text-align: justify;">I would love to be able to wrap up by saying “do the above and you’re done.” But that’s not how commerce works today. The rapidly evolving world of multipoint marketing means that brands must constantly tweak the experience that their website delivers to each visitor segment based on everything they know about that segment. That knowledge includes data drawn from all channels — something a website can provide if the proper technology is in place to tap it.</p>

			<content:encoded><![CDATA[<p style="text-align: justify;"><strong>Ahmed Matiur Rahman</strong></p>
<p style="text-align: justify;">Paper is a thin material mainly used for writing option, printing upon or for packaging. It is produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses and drying them into flexible sheets. Paper is a versatile material with many uses. Whilst the most common is for writing and printing upon, it is also widely used as a packaging material, in many cleaning products, in a number of industrial and construction processes, and occasionally as a food ingredient, particularly in Asian cultures. <span id="more-1323"></span>The word paper derives from the Greek term for the ancient Egyptian writing material called papyrus, which was formed from beaten stripes of papyrus plants.</p>
<p style="text-align: justify;">Paper is chiefly used for written communication. The earliest paper was papyrus, made from reeds by the ancient Egyptians. Paper was made by the Chinese in the second century, probably by a Chinese court official named Cai Lun. His paper was made from such things as tree bark and old fish netting. Recognized almost immediately as a valuable secret, it was 500 years before the Japanese acquired knowledge of the method. Papermaking was known in the Islamic world from the end of eight century A.D.</p>
<p style="text-align: justify;">Knowledge of papermaking eventually moved westward, and the first European paper mill was built at Jativa, in the province of Valencia, Spain, in about 1150. By the end of the 15<sup>th</sup> century, paper mills existed in Italy, France, Germany, and England, and by the end of the 16<sup>th</sup> century, paper was being made throughout Europe.</p>
<p style="text-align: justify;">Paper, whether produced in the modern factory or by the most careful, delicate hand methods, is made up of connected fibers. The fibers can come from a number of sources including cloth rags, cellulose fibers from plants, and, most notably, trees. The use of cloth in the process has always produced high quality paper. Today, a large proportion of cotton and linen fibers in the mix create many excellent papers for special uses, from wedding invitation paper stock to special paper for pen and ink drawings.</p>
<p style="text-align: justify;">The methods of making paper is essentially a simple one – mix up vegetable fibers, and cook them in hot water until the fibers are soft but not dissolved. The hot water also contains a base of chemical such as lye, which softens the fibers as they are cooking. Then pass a screen-like material through the mixture, let the water drip off and/or evaporate, and then squeeze or blot out additional water. A layer of paper is left behind. Essential to the process are the fibers, which are never totally destroyed, and, when mixed and softened, from and interlaced pattern within the paper itself. Modern papermaking methods, although significantly more complicated than the older ways, are developmental improvements rather than entirely new methods of making paper.</p>
<p style="text-align: justify;">Probably half of the fibers used for paper today come from wood that has been purposely harvested. The remaining material comes from wood fiber from sawmills, recycled newspaper, some vegetable matter, and recycled cloth. Coniferous trees, such as spruce and fir, used to be preferred for papermaking because the cellulose trees are called “softwood” by the paper industry. Deciduous trees (leafy trees such as poplar and elm) are called “hardwood.” Because of increasing demand for paper, and improvements in pulp processing technology, almost any species of three can now be harvested for paper.</p>
<p style="text-align: justify;">Some plants other than trees are suitable for paper making. In areas without significant forests, bamboo has been used for paper pulp, as has straw and sugarcane.</p>
<p style="text-align: justify;">Most paper is makde by a mechanical or chemical process. Flax, hem, and jute fibers are commonly used for textiles and rope making, but they can also be used for paper. Some high-grade cigarette paper is made from flax.</p>
<p style="text-align: justify;">Cotton and linen rags are used in fine-grade papers such as letterhead and resume paper, and for bank notes and security certificates, the rags are usually cutting and waste from textile and garment mills. The rags must be cut and cleaned, boiled, and beaten before they can be used by the paper mill.</p>
<p style="text-align: justify;">Other materials used in paper manufacture include bleaches and dyes, fillers such as chalk, clay, or titanium oxide, and sizings such as rosin, gum, and starch.</p>

			<content:encoded><![CDATA[<p style="text-align: justify;"><strong>David A. Harding</strong></p>
<p style="text-align: justify;">There are five kinds of <strong>computer backup storage</strong> each with its own advantages and disadvantages you should consider. We’ll briefly describe each type of <em>computer backup storage</em> in this article so you can choose the best option for you. I have definitely learned the hard way, over the years, about the importance of backing up files. Many times I thought my files were safe and secure when they actually were not! I also sometimes just simply forgot to backup all the files and now have a list of the most important computer files to backup.</p>
<p style="text-align: justify;"><strong>No Backups</strong></p>
<p style="text-align: justify;">Even a few years ago, it would be crazy to suggest to people that they use computers without making regular backups, but today it’s a very real and very legitimate option. Thanks to the prevalence of “cloud” applications from Google and other companies, many users today store all of their files and applications entirely on the Web.</p>
<p style="text-align: justify;">If you use hosted applications for everything, then you have nothing to worry about when your computer fails. You just need to stand up, walk to another computer, and log in to start working where you left off.</p>
<p style="text-align: justify;">This option isn’t for everyone. Anyone who still needs an offline application or wants to keep their files private from Google still needs to store files locally and should make Easy Secure Backups using the methods described later in this article.</p>
<p style="text-align: justify;">We expect a significant rise in the number of users who store all of their data in the cloud when Google releases its upcoming Chrome operating system for computers.</p>
<p style="text-align: justify;"><strong>Same Disk Backups</strong></p>
<p style="text-align: justify;">At first, making a backup to the same disk doesn’t make any sense. If the disk fails, you lose both the original and the backup copies. Plus, making a same disk backup will run slowly—hard drives aren’t designed to quickly copy data from one part of the disk to another part of the same disk.</p>
<p style="text-align: justify;">But a same disk backup can give you access to an important computer backup storage feature: the ability to save multiple versions of the same file. For example, you can make a new copy of your accounting Excel worksheet every time you save so that you can always restore an older version if you make a mistake. You probably also want to do this with important Word documents in case you accidentally delete a few paragraphs or pages, your Outlook email files in case you delete an important email, and many other applications.</p>
<p style="text-align: justify;">Although a same disk can be useful, you should always remember that a disk failure will wipe out both original and backup copies, so this method is best used in combination with computer backup storage methods described later in this article.</p>
<p style="text-align: justify;"><strong>External Backup Disks</strong></p>
<p style="text-align: justify;">External backup disks is one of the cheapest methods of computer backup storage and probably also the method that offers the best privacy for your files. Best of all, external backup disks are easy to use with Windows.</p>
<p style="text-align: justify;">Most external disks these days use USB 2.0, although a few disks use Firewire or eSATA. In any case, all you need to do is plug in your external disk and wait for Windows to load it (also called mounting). After you disk mounts, go to the Windows Backup Wizard located in the System and Maintenance menu of the Control Panel. Set up a backup and start it right away.</p>
<p style="text-align: justify;">You have so many choices when buying an external hard drive to use for computer backup storage. You can now get a 2 TB External Hard Drive.</p>
<p style="text-align: justify;">Your first backup to an external drive will take a while, but your second and subsequent backups will go much faster because Windows transfers only the files that have changed.</p>
<p style="text-align: justify;">After you make your backup, you need to safely remove your disk and then store it somewhere safe. It’s no use to you if the same natural disaster that destroys your computer also destroys your backup. You also need to keep the disk safe from attackers or your private files could fall into the wrong hands. For both purposes, we recommend storing your backup disk in a sturdy fire-proof safe.</p>
<p style="text-align: justify;"><strong>Network Storage</strong></p>
<p style="text-align: justify;">At businesses and even in homes, more and more people are using Network-Attached Storage (NAS), which is simply disk drives accessible over your local network. NAS offers almost all of the benefits of external backup disks and also Internet-based backups for computer backup storage. Many devices made for small and home offices are also very easy to use.</p>
<p style="text-align: justify;">Similar to external disks, a NAS plugs into your computer—but instead of plugging into your computer directly, in plugs into your network router. You can then create a folder on your computer that stores all the files on your NAS. You can backup files to this folder like normal and you can also share files with other people on your same local network.</p>
<p style="text-align: justify;">Because the NAS is separate from your computer, there’s much less chance it will be destroyed by any calamity that strikes your computer. You can even store NASes in a safe place where they’re resist fire damage and thieves while still connected to the network, providing the ultimate in safety and convince.</p>
<p style="text-align: justify;"><strong>Computer Backup Storage With RAID</strong></p>
<p style="text-align: justify;">Another great feature available in higher-end NASes is the ability to use a Redundant Array of Independent Disks (RAID) for extra safe backups. If you use your computer for business and worry about losing thousands of dollars of data to a disk drive crash, a NAS with RAID should be an important part of your computer backup storage plan.</p>
<p style="text-align: justify;">RAID is also available for all full-sized PC computers using a special card called a RAID controller, but this method can require a lot of hassle and unskilled users can easily wipe out all their data by choosing the wrong option. With a RAID-enabled NAS, all you usually need to do put a second disk drive in your NAS, browse to a Web interface, and click a button to enable RAID computer backup storage protection.</p>
<p style="text-align: justify;">
<p style="text-align: justify;"><strong>Internet-Based Backup</strong></p>
<p style="text-align: justify;">The sudden popularity of Dropbox has brought increased attention to the already-established industry of Internet-based backups. Non-geeks will probably appreciate Internet-based backups the most, as very little setup is required. For example, to use Dropbox, all you need to do is install the Dropbox application, create a Dropbox account, and copy your files to a Dropbox folder. Dropbox will do all of the rest.</p>
<p style="text-align: justify;">Dropbox and promise better security, but you’re still trusting someone else with all of your most important files. You can get online easy secure backup that is guaranteed against data loss, however it costs an absolute fortune. Livedrive offer unlimited online storage.</p>
<p style="text-align: justify;">The main disadvantage of Dropbox is that you trust the security of your data to Dropbox. Although Dropbox uses high-security technology, any hacker who ever figures out how to get around it will have access to the private files of millions of customers—and that’s an awfully tempting target. In contrast, if you keep your own computer backup storage, you only need to worry about direct threats against your computer.</p>
<p style="text-align: justify;"><strong>Conclusion: You Can’t Avoid Computer Backup Storage</strong></p>
<p style="text-align: justify;">Whether you choose to keep your data in the cloud or store it on a high-end NAS, you should still make a clear choice about how you want to keep your computer backup storage before something goes wrong and your data is suddenly gone. If you organize your computer files neatly you will find that any kind of backup is a whole lot easier!</p>

			<content:encoded><![CDATA[<p style="text-align: justify;">Cyber attacks are already upon us but the rules of digital warfare have yet to be agreed upon. Is it time, as an influential think tank believes, for a digital Geneva Convention?<br />
Is it even possible when the Internet was designed without country borders and when defining what a &#8220;cyber-war&#8221; constitutes is near-impossible? <span id="more-1261"></span><br />
&#8220;We come in peace&#8221; reads the tagline of the Chaos Communication Congress in Berlin.<br />
The event, which attracts &#8220;thousands of hackers, scientists, artists, and utopians from all around the world&#8221;, is a timely reminder that not all hackers are obsessed with unearthing secrets or bringing down governments.<br />
They are keen to point out that the definition of &#8220;hacker&#8221; can mean both a technical expert who modifies things as well as the increasingly common definition of someone who digitally intrudes.<br />
But there are worries from governments around the world that a &#8220;cyber-war&#8221; is just around the corner, moving from conventional battlefields into the digital world.<br />
&#8220;Cyber-threats are not on the horizon, they are upon us,&#8221; says US Senator Robert Menendez.<br />
He is introducing a bill to the US Congress, following reports of cyber attacks on Nasdaq OMX Group and both oil and gas companies, aimed at &#8220;strengthening cybersecurity&#8221;.<br />
Despite the concern, many still do not realise the effects this seemingly impending battle could have.<br />
Most of our infrastructures rely on computer technology to function properly &#8211; from railways to electricity companies and national defence systems &#8211; so failure or malicious attacks on them matters more than just not being able to read an e-mail.<br />
If these things were threatened, some commentators believe it is not just the internet at threat, but many lives.<br />
&#8220;The attackers are constantly developing new strategies,&#8221; John Bumgarner, chief technologist of the US Cyber Consequences Unit, told BBC Newsnight.<br />
&#8220;There are thing out there right now that the public doesn&#8217;t really know about &#8211; technologies that can be embedded in systems that will run but you will never see.<br />
&#8220;Things already exist to do things like turn off the power grid, disrupt water systems, disrupt manufacturing processes GPS [devices] in cars have the capability to give wrong directions and your car could catch fire potentially depending on how you program it.&#8221;<br />
Others, such as Frank Coggrave, vice president of digital investigators Guidance Software, believe these sorts of comments are &#8220;edging towards hysteria&#8221;.<br />
But what even is a cyber-war? And how does anyone know when it begins or who is fighting who?<br />
&#8216;Other-than-war&#8217;<br />
&#8220;There is no clear, internationally agreed upon definition of what would constitute a cyber-war. In fact, there is considerable confusion,&#8221; said a report released at the Munich Security Conference by think tank The EastWest Institute.<br />
Its paper, titled Working Towards Rules for Governing Cyber Conflict, says that &#8220;the current ambiguity [about what constitutes cyber conflict] is impeding policy development and clouding the application of existing Convention requirements&#8221; and perhaps the idea of peace and war is too simple in the digital age when the world could find itself in a third, &#8220;other than war&#8221; mode.<br />
In basic terms, it is calling for something similar to the Hague or Geneva conventions that govern conventional warfare.<br />
While seemingly simple in theory, this could be very difficult to put into practice.<br />
&#8220;It&#8217;s a challenge and [governments are] doing a valiant job but the whole area of cyberspace and cyber-attack is very difficult to quantify,&#8221; says Mr Coggrave.<br />
&#8220;Who is performing the attacks? Just look back over the last year at the Stuxnet attack on Iran&#8217;s nuclear reactors.&#8221;<br />
The Stuxnet attack &#8211; where specific types of industrial controls were targeted and damage is believed to have been done to Iran&#8217;s uranium enrichment programme &#8211; was described as enemies of Iran &#8220;seeking to wage a cyber war&#8221; by the country&#8217;s communication minister.<br />
&#8220;It&#8217;s still questionable who actually did it,&#8221; says Mr Coggrave.<br />
&#8220;Was it the Israelis, the Chinese, the CIA or M16? When you come to cyber-attacks, because of the interconnectivity of the world, it is actually so difficult to attribute [responsibility for the attack to any one party] that putting in rules of engagement is valiant but probably flawed.&#8221;<br />
Many experts believe that this attack, unlike most others before it, was carried out with some form of state involvement &#8211; citing the proficiency and scale of the attack.<br />
&#8216;Indiscriminate&#8217; attack<br />
While this attack was quite specifically targeted, it is very difficult to aim at one organisation or country. Even the Stuxnet worm has affected computers in 10 countries.<br />
This means that neutral or humanitarian organisations online could be hit in the metaphorical crossfire. The job that the Red Cross does in &#8220;kinetic&#8221; &#8211; or traditional &#8211; warfare could be impossible to recreate in the virtual world.<br />
&#8220;Viruses tend to be indiscriminate,&#8221; says Mr Coggrave.<br />
&#8220;And there is blurring between cyber-warfare and cyber-terrorism if you generate a virus that attacks a Windows machine for example, how can you make sure it&#8217;s a machine run by MI6 and not a machine run by the Red Cross?&#8221;<br />
According to the Congressional Service, &#8220;US officials now consider cyberspace to be a domain for warfare, similar to air, space, land, and sea.&#8221;<br />
The difficulty is, with the global nature of the web, working out which territory belongs to whom and what bits of the web are friendly and which are hostile.<br />
But, if battle lines can be drawn and territory can be won or lost, those like the technical wizards at the Chaos Congress could find themselves as digital infantry on the virtual frontline.</p>

<div id="_mcePaste">Every new organism, whether it is a planet, fish, animal or human, resembles its parents – and yet it differs from them. For example, children may look like one parent or the other, but usually they have some features of each parent.<span id="more-1233"></span> What has happened it that the parents have passed down to the children certain characteristics. The children have “inherited” them. So heredity is the study of how offspring resemble their parents.</div>
<div id="_mcePaste">The unit of heredity is called the “gene”. Genes are larges molecules found in the nuclei of both sperm cells and egg cells. Within the nucleus of each cell are long, thin strands, or threads. They are called “chromosomes”, and they carry the genes.</div>
<div id="_mcePaste">Since chromosomes occur in pairs, their genes are also paired. The chromosomes of a cell may contain hundreds of thousands of pairs of genes. Each gene pair controls one or more feature of the organism, such as color of hair, shape of nose, size of body and so on.</div>
<div id="_mcePaste">There are many “laws” of heredity, which means that the process takes place in certain ways. For example, every trait that is inherited depends on a single “factor”, and each factor behaves independently. Because a certain trait is inherited from the parents, it doesn’t mean that any other trait will also necessarily be inherited. In other words, the factors, or genes, have nothing to do with each other.</div>
<div id="_mcePaste">Some genes carry traits that are “dominant”, and others carry traits that are “recessive”. For example, the gene for curly hair seems to be dominant to the gene for straight hair. When both parents are curly haired, they usually have curly haired children. But if each parent carries a recessive gene for straight hair, some children may be straight hair.</div>
<div id="_mcePaste">Scientists have studied such human traits as color of eyes, hair, and skin, so that they usually can tell how they will be inherited by people whose family history is known for several generations.</div>
