Understanding Ultrabooks

In fact, Intel expects ultrabooks to occupy around 40% of the total laptops launched in 2012. We conversed with Karen Regis, Intel’s Director of Ultrabook Marketing Strategy, to get insights about the big picture.

Following excerpts from our interview:

1) Laptops vs netbooks vs ultrabooks — what’s the difference between them?

There are many types of mobile devices for consumers these days, and it’s important for buyers to understand the differences between them to make sure they choose the right device for their needs. Netbooks are great for content consumption and light productivity and offer the most affordable price points. Ultrabooks are for users looking for a full PC experience in an ultra sleek, ultra stylish design. They have the horsepower for just about any productivity task, but also provide great battery life, the ability to wake up in a flash and built-in security – all at mainstream system price points.

2) In many ways, the netbook segment was a much bigger breakthrough (from a technical perspective) than all the hype surrounding ultrabooks, which is just natural evolution of laptops. Would you agree that the term ultrabook is a marketing gimmick?

Intel expects Ultrabook devices to be as transformational to mobile computing as Intel Centrino Mobile technology was more than eight years ago. Remember, Intel’s vision for the Ultrabook entails a multi-year, industry-wide endeavor that will roll out in phases with new experiences and features added over time. It’s about driving innovation and integrating capabilities that users want and may not even know yet that they need – much like Centrino helped make Wi-Fi a must-have in laptops. Some of the nearer term innovations we expect to see include hybrid devices (both tablet and laptop functionality) as well as technologies like touch and sensors. Intel is committed to the Ultrabook category, and we’re seeing very strong support from our partners as well.

3) This is the first time since 2003 and Centrino chips that Intel is promoting a product such aggressively in the market. Why are ultrabooks so important? How do they feature in Intel’s roadmap?

Yes, on April 4, we announced our new Ultrabook marketing campaign, Intel’s largest in nearly a decade. The global campaign theme is how Intel-inspired Ultrabooks are ushering in “a new era of computing” – making everything else seem like ancient history/old fashioned compared to an Ultrabook.

The creation of the Ultrabook category was shaped by extensive user research and reflects what users value most in a mobile device – a no-compromise, most complete, satisfying and more secure computing experience. We are very excited about this category and are looking ahead to our Ivy Bridge and Haswell platforms to continue to evolve and bring new capabilities to Ultrabook devices in the next several years.

4) How do you respond to the criticism that the ultrabook is a desperate attempt to rekindle excitement among laptops, more importantly among consumers more keen on buying a tablet?

Worldwide PC unit shipments continue to grow at double-digit rates. This is one of the reasons for Intel’s recent record revenues and earnings. We believe that PCs will continue to play a key role in people’s personal computing needs.

At the same time, people have rapidly evolving requirements for personal computing in terms of responsiveness, capabilities, increased security and mobility. Intel aims to help drive these changes. Whether it’s a tablet, PC, Ultrabook or hybrids we aim to deliver great experiences that satisfy people’s needs, no matter what the device.

5) Is an ultrabook a poor man’s MacBook Air?

Intel’s vision for Ultrabook devices entails a multi-year, industry-wide endeavor that will roll out in phases where new experiences and features will be added over time. Intel aims with the Ultrabook category to deliver new experiences that people want and will love. Devices coming in the future will blend the best of the laptop experience with aspects of other consumer electronic devices.

7) We’ve tested majority of the ultrabooks so far and they all offer close to 5 hours of battery life on a single charge. How has Intel managed to do this — make thin ultrabooks last longer than fatter laptops with bigger and better batteries?

Great battery life is one of the requirements to be called an Ultrabook. Ultrabook devices offer at least 5 hours of battery life with many providing 8 hours or more, even in the sleekest form factors. In general, we expect to see greater use of Lithium polymer batteries (such as are used in phones) in Ultrabook devices. Intel is focused on driving innovations in battery design and technology in the industry to continually improve the user experience in terms of ever better battery life in ever more attractive designs. This is one of the focus areas of the Ultrabook Fund (read more here).

8) Regarding OEMs and various partners, is Intel laying down minimum specifications for ultrabooks to ensure a standard benchmark for end user experience?

Intel works closely with its industry partners to ensure that Ultrabook devices consistently deliver a compelling and unique value proposition to customers. In order for a system to be classified as an Ultrabook and use the Ultrabook trademark, a certain set of guidelines must be followed. The guidelines may evolve over time as new capabilities come to market. A verification process is in place to help ensure the consistent and outstanding experience we aim to deliver.

9) What are some of the main challenges that may hinder ultrabooks from completely dominating the personal computing market?

We’re thrilled with the reception to Ultrabook devices so far. There’s already been a lot of enthusiasm around the category. We believe there will continue to be a spectrum of types of products with different capabilities and features that meet consumers’ varying needs. There will always be users, though, who are looking for companion devices, like a netbook, to complement their Ultrabook or laptop. There are also those who value certain features more. For example, a gamer may want a desktop system with maximum performance. Or a road warrior may value weight and size as the top feature. We value choice and a spectrum of options for all types of users.

10) This year marks Intel’s first steps into the tablet and smartphone market with Medfield chips. How important is this market to Intel and how does it affect sales of ultrabooks?

I’m not the right person to comment on Medfield, but what I can tell you is that whether it’s a tablet, PC, phone or Ultrabook Intel aims to deliver great experiences that satisfy people’s needs, no matter what the device.

12) How committed is Intel to the future of ultrabooks beyond the upcoming Ivy Bridge architecture?

Intel’s vision for Ultrabook devices entails a multi-year, industry-wide endeavor that will roll out in phases where new experiences and features will be added over time:

A) Intel’s latest Ultra-Low Voltage 2nd generation Intel Core processors started the transition to Ultrabook systems by enabling a new class of thin, light, beautiful designs with mainstream price points. Many systems are available today.

B) 3rd generation Intel Core processors (codenamed “Ivy Bridge”), Intel’s next generation chip, is scheduled for availability very soon. Ultrabook systems based on this new family of processors will bring improved power efficiency, smart visual performance, increased responsiveness and enhanced security. Complimentary USB 3.0 and Thunderbolt technologies are also part of Intel’s ongoing work to drive the PC platform forward.

C) “Haswell” is the third step toward accelerating the category of Ultrabook devices. With “Haswell,” Intel will change the mainstream laptop thermal design point by reducing microprocessor power to 10-20 watts – half of today’s design point.

Android Phone Vs Windows Phone Vs i-Phone

Android Phone Vs Windows Phone Vs i-Phone


Smooth Experience And Fresh Design
Windows Phone comes with a design that has been made from scratch, called the Metro UI. This fresh new interface consists of tiles, rather than the icon-based design that has been, dare we may say, copied by everyone from the iPhone. The tiles are “live”, meaning that they actually show the updated status of the applications they are meant for. The animation effects are also different, and the overall user experience is very smooth. Part of the reason for this is that Microsoft has put stringent hardware requirements for devices to qualify for this platform, which effectively protects against fragmentation that has been experienced by other mobile platforms such as Android.

Deep Social Networking Integration And Web Browsing
TechTree Blog: 5 Reasons Why Windows Phone Will SucceedOne of the first things that you will notice when you start using a WP smartphone is the amount of social network integration that has been built into this platform. You can log into FacebookTwitterWindows LiveLinkedIn, and a host of other social networks and get instant status updates on the home screen through the People tile. The phone’s contact list automatically gets populated with your friends’ details, from the networks you have signed into. In addition to the above, users can also sign into email services of their choice and contacts saved over there are also downloaded automatically to the device, while a live tile for the mail service is made available on the home screen for quick and easy access. Last but not the least, we have to mention that WP devices provide one of the fastest and smoothest internet browsing experience in the current crop of mobile phones, and the credit for this goes to its Internet Explorer browser that uses the same core and rendering engine as IE9 for desktop.

An Increasingly Attractive Application Store
TechTree Blog: 5 Reasons Why Windows Phone Will SucceedSmartphones these days are not just about making phone calls, as more and more users want to use applications for different tasks and the success of a platform depends on its app ecosystem. WP has its own Marketplace application store that distributes free and paid apps. The number of apps is nowhere near that of competing stores, but it is definitely increasing, with the current number now standing at over 80,000. The quality of apps is generally good and Microsoft exercises a strict policy of not allowing “socially unacceptable” programs, possibly with the aim to protect young users against the “evils of the online world”. One of the good things about this app store is that even if it is a paid app, you can still download and try it out before deciding if you would want to buy.

Microsoft Applications Integration
TechTree Blog: 5 Reasons Why Windows Phone Will SucceedWP devices come with integrated Microsoft applications. The Xbox Live tile grants users access to some Xbox 360 features via the “Games hub”. Users can log into the phone using the same credentials as that for the console and purchase games, set their avatar in a 3D fashion, and also play several multiplayer games right from their handset, even as they are on the move. WP phones also come with free Microsoft Office Mobile to let you open, create, or edit MS Office documents including WordExcelPowerPoint,OneNote, and SharePoint. Files can be saved either locally or to SkyDrive and Office 365so that they can be accessed later through cloud servers.

Timely Updates For OS And Apps
TechTree Blog: 5 Reasons Why Windows Phone Will SucceedMicrosoft seems to have taken cue from the negative feedback for its previous mobile OS and made sure that WP devices receive timely updates for the OS as well as for the apps thus far. Updating has been made very easy with the possibility of downloading and installing OTA (over the air) or by connecting the phone to a computer. Similar to the updates for its desktop OS, these WP updates iron out bugs and plug holes in an effort to deliver a better user experience.

Windows Phone smartphones are still awaiting widespread adoption, but we think that its popularity will increase if Microsoft continues to make sure that it does not waver from the above advantages that are currently offered by this platform.

There are certain perks to working as a tech journalist: coffee is free and plentiful, trade shows are equal parts fun and frantic, and most of all, we get the chance to play with lots and lots of new toys. I’ve personally had the luck to be able to swap handsets pretty much bi-weekly for the last couple of months, and find it kind of a bummer that Windows Phone 7 hasn’t really been embraced as the solid mobile platform that it is (I said it’s a bummer, I didn’t say we didn’t see it coming).

Regardless of the numbers, WP7 is one of our favorite mobile platforms, outshining Android in almost every aspect. Don’t believe me? Well, allow me to try and change your mind.

Streamlined User Interface

Android’s are different depending on the SKU of the handset. In other words, the UI you’ll be dealing with when using, say, a Motorola handset, will be radically different than one from Samsung or HTC. The ambiguity can be disconcerting. With WP7, you know what kind of interface you’re going to be working with, regardless of the handset manufacturer. We’d imagine that an un-tweaked user interface would also make lives easier for developers, as well. We love some Android user interfaces, but loathe others. With WP7, at least you know what user interface to expect, regardless of the handset maker. Speaking of which…

WP7 Has An Easier-To-Use Interface

It really does. And look, we get it. An Android is a power user’s phone, and we know that if you’re really looking for power-use, you’ve got to be willing to learn some things. But we’re the geeky minority here, and you’ve got to keep in mind that most people are looking for a phone that makes it easiest to do their day-to-day tasks. Keeping that in mind, WP7’s “tile” system is simply easier to organize and find the things you need to throughout the day. It looks cooler too; way cooler, actually.

WP7 Has Apps That Aren’t Crap

Open-source is good, and it’s a compelling reason to support Android as a mobile platform, but let’s face it: You’ve got to sift through some real $#@t in the Android Marketplace to find apps that are worth downloading, much less buying. Most people fail to realize that the Windows Mobile SDK has been around for quite some time now, and it shows in the Marketplace, especially on the gaming side of the spectrum. Many of the games we played featured awesome 3D graphics and a level of polish simply not(yet)-to-be-found in the Android hemisphere. Microsoft has a far stricter criteria set than Google about which apps and games can populate their respective marketplace. Oh, and now that we’re on the topic of gaming…

Microsoft LIVE Integration Is Bad Ass

If you’re achievement junkies like we are (you know who you are), then a WP7 handset is a must-have. Have a game on Xbox or PC that you love playing? Pop over to the Windows app store; chances are there’s a mobile version of that same game, where you can continue earning points and unlocking achievements with your handset. You can also keep tabs on your buddies’ achievements, and tweak and enhance your Xbox Live avatar. Granted, this integration is still in an infancy stage, but we’d be willing to bet that we’ll be seeing deeper and more intuitive connections between gaming and phones in the near-future. Forward progress is good progress.

Microsoft Mobile Office Integration

We were actually blown away by how deep this rabbit-hole goes. Microsoft Word Mobile Edition, by way of an example, is actually a very intuitive little program, allowing you remote access documents using SharePoint Server 2010, you can use the “find” tool to look for particular words or phrases, and you can even email documents directly from the program.

We’ve had the pleasure of testing some Android phones that can dock with workstations to function as a laptop; imagine how crazy it would be if Windows launched a similar product with a full-fledged Office Suite. That’d be one step closer to a true fusion between phones and computers, and we’re all for that.

Microsoft Isn’t Constantly Getting Sued by Apple

Whether targeting HTC a year ago or Motorola last fall or even Samsung (which is remarkable seeing how they are a flat out key supplier of Apple’s hardware components) just a few days ago, Apple has been regularly suing the hell out of Android handset makers; mostly in regards to hardware and software patents. So why is Apple seemingly ignoring WP7 in the courts? Well, there could be numerous reasons: Optimistically, it could be because the software and hardware developments on WP7 are truly original and innovative, meaning Apple can’t accuse Microsoft of lifting their ideas. A more realistic reasoning? Apple doesn’t see WP7 as that big of a threat…yet.


This is speaking from personal experience with various handsets across both platforms, but to put it simply, WP7 has just been a more stable experience. Apps like Facebook and Netflix simply run the way they were meant to with far less of the hiccups and crashes found on the Android platform. This runs parallel with the overall theme behind WP7 mobile devices: Simplicity. Granted, WP7 had to forgo some of the more complex actions Androids are capable of (i.e. lack of tethering support, lack of ability to capture screenshots, no multi-tasking), but to us, that’s a worthy trade for a phone that will do what you want it do, every step of the way.

Zune is a Native Client, and it’s Not Pay-Per-Song

We like Zune as a service—you pay a monthly fee and can download as many songs as you want, as opposed to being pigeonholed into paying per song, like with Apple and Android. Also, we really enjoy the fact that Zune is a native client that comes fresh out-the-box with WP7—setting up music services on an Android involves downloading various apps (like Google Music, which then has to synch to your Google Wallet, which then has to synch to your Google Music Server, which then needs a Gauntlet from Moredore to unlock your songs, which then needs…well, you get the point) that is just sort of a hassle, and glitchy to boot. Again, simplicity reigns supreme.

Snappier Keyboard

All right, we’re getting down to the nitty-gritty, and this is a minor nit to pick, but for the most part (with the exception of the Android Sprint Galaxy, which actually featured a physical slide-out QWERTY keyboard), Windows Phone 7 had a snappier, and more importantly, a more consistent keyboard that was snappy and accurate, regardless of the device. And, though Droid offered a few keyboard-contenders with the Galaxy S2 and the Incredible, others were really bad, (ahem, Droid X2, cough).

No Ad-Ware!

That’s right, there is nary a pop up ad to be found, whether you’re in the Windows Marketplace, or playing a game. There is nothing more irritating when using an Android that having to manually close pop-up adds, many of which appear mid game. There are, indeed, advantages to more stringent app restrictions, and WP7 seems to have found a perfect balance.

The Brief Verdict:

So to get you started, here’s a quick primer on iPhone, Android, and Windows Phone (sorry, no BlackBerry considered in the race), and a smattering of the most common questions about smartphone OSes I’ve received from you.

iPhone 4S in a nutshell

  • Runs Apple’s iOS 5 operating system
  • Available on three carriers: AT&T, Verizon, Sprint
  • Available on three storage sizes: 16GB, 32GB, 64GB
  • Easiest compatibility with iTunes, Apple ecosystem, and products
  • Form factor: One 3.5-inch screen (on the smaller size by today’s standards)

  • Next big operating system release: Unknown. Version 7.5 Mango released in September

Android FAQ

Question:Why there is delay on update for Android devices, and will Ice Cream Sandwich bring the solution for this problem?
With Android phones, we’re at the mercy of manufacturers and carriers who need to test the new OS with the additional skins, overlays, or additional software these phones might have. My colleague Bonnie Cha wrote a great story explaining how OS updates work. So the answer is no, Ice Cream Sandwich (or ICS) won’t fix this. However, back in May, Google and several key manufacturing partners agreed to work together to bring phones released within 18 months of a new OS updated to the latest OS version. Unfortunately, neither Google nor other manufacturers have been forthcoming with how this is playing out in practice. For now, the surest bet to get the latest Android OS is to get the Galaxy Nexus or Samsung Nexus S phone (available for AT&T, T-Mobile, and Sprint).

Q: I am looking forward to buying the Galaxy Nexus. However, which phone would you select between it, the Motorola Droid Razr, and the HTC Rezound?
If it’s specs you’re wondering about, check out my former colleague Nicole Lee’s helpful chart comparing the three. If it’s the overall look and feel, well, that’s just a question I can’t answer for you. What do you value most: the camera, the speed, the price, the way it feels in your hand? They’re all fast, they’re all premium, and they all run on Verizon’s phenomenal 4G LTE network.

The Droid Razr and Galaxy Nexus are thin, but the Galaxy Nexus and Rezound have better screens. The Galaxy Nexus has a 5-megapixel camera, but the Droid Razr’s isn’t my absolute favorite on the market, either. The Droid Razr is more stylish. The Rezound comes with Beats by Dr. Dre headphones and a music algorithm, but the Galaxy Nexus is the first to have the powerful Ice Cream Sandwich OS (the other two will get it as well, but you’ll have to wait until early 2012.) Yet, the Galaxy Nexus isn’t even available yet, while the other two are. I recommend getting yourself to a Verizon store and getting your hands on the other two devices to see how much you connect with them, then go from there.

iPhone FAQ

Q: With the iPhone 4S out, would it be better to wait for the iPhone 5? My 2-year contract renewal is up in 2012. I am hearing possibly summer 2012 for iPhone 5.
If you’re still riding out a contract, keep waiting. The iPhone 4S is a great device, but it’s not worth breaking a contract for or buying fresh unless you need Siri or a better camera.

Windows Phone FAQ

Q: Which is easier to use: Windows Phone, iOS 5, or Android 4.0?
Windows Phone has the cleanest OS of the three and is the easiest for getting in and out, at least as far as the main screens go. With only two home screens to toggle between, it’s hard to get lost. However, the edgy “metro” look may not be for everyone, and the apps look completely different. There are also a few tricks you need to know about to fully use the OS, like pressing and holding on “live tiles” to pin, unpin, and get more options, and using your finger to pull down the signal strength meter and battery meter while you’re on the Start screen (these otherwise disappear from view.) There are other tricks, too–tools in Bing you may not think to look for, and actions when you press and hold the Home and Back buttons.

The iPhone and Android have their own quirks as well, and I don’t consider the other two particularly hard to learn, though with its large icons and limit to two screens, it’s easier to navigate Windows Phone.

Do you know if WP7.5 is limited to single-core processors and how that would impact the performance of the devices?
Right now all Windows phones are single-core, and I can’t complain about performance issues. With the way that the OS handles tasks and task-switching, dual-core processing may not be strictly necessary. That said, as all phones join the processor race, I’m sure we’ll eventually see dual-core Windows Phones with much larger screens and many more features advanced as well.

Q: Do you think Windows will have the kind of app choice that iOS or Android do? I have not heard much about what Microsoft is doing to bring in developers or how they will play the app market.
Windows Phone is really ramping up its app presence. In a few months’ time, the population of the app Marketplace has shot from 18,000 to 40,000, and is growing. While they need to keep wooing developers to create interesting apps, there’s also the danger of choking on too much unnecessary app sludge, an argument one could levy against iOS (500+K apps) and even Android (300K).

Battery life

With battery life being one of the biggest issues, does any one of the operating systems seem to handle that better than the others? If so, which and why?
How a phone’s operating system handles resources is part of the equation, but not as key a factor in our opinion as the hardware and the capacity of the battery. If it seems that Android phones experience faster battery draining than the iPhone, that’s likely because there’s so much variance among different hardware specs and manufacturers. To be fair, the recently launched iPhone 4S has purportedly shorter battery life than several Android phones as well. There are also some Android phones with better battery life than others.

The real question is when we can stop wondering if our smartphones will last longer than a day before needing a recharge. Here’s some good news we still have to wait to see: researchers are redesigning the lithium ion battery to charge faster and hold charges longer, up to three days. I, for one, am relieved to know that smart chemists are hard at work, and that a fix is coming.

How to Decrease Web Page Loading Time…


How to Decrease Web Page Loading Time….


By now everyone in SEO industry is aware that web page loading is a part of seo/organic search and if you do not work on your page loading time all your effort on SEO may just go down the barrel. From the OfficialGoogle Blog

Speeding up websites is important – not just to site owners, but to all Internet users. Faster sites create happy users and we’ve seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don’t just improve user experience; recent data shows that improving site speed also reduces operating costs. Like us, our users place a lot of value in speed – that’s why we’ve decided to take site speed into account in our search rankings. We use a variety of sources to determine the speed of a site relative to other sites.

You should not worry too much because site speed is just small weightage when it comes to page ranking. Still the important factors are like backlinks, relevancy and 200 others. But does it mean that if you are not affected by site speed does it mean you should now work on your page’s speed. I don’t think so. You should work on web page speed to the extent you can so that you not only make better user experience but in the long run, may not be penalized for slow page loading by Big G when site speed factor becomes a bit more major factor for search engine results.

1. Better Web Host

One of the best place to start with better site experiences is your host. If you do not have good and reliable host the other point may actually be of no use.

2. Compress output

Images take the large chunk of the total time to view any page yet HTML is considerable part of the content delivered by any server. HTML is static text content that can be reduced considerably if you compress the output. Modern day Web servers do support compressed output and all modern browsers are not far behind when rendering the compressed output as well. If any browser that does not support compressed output web servers render normal output to them and so it is wise option to enable compressed output for your server as well.

For PHP and Apache just adding couple of lines in your apache configuration file can actually do this for you.

<IfModule mod_deflate.c>
	SetOutputFilter DEFLATE
	# file-types indicated will not be compressed
	SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|rar|zip|pdf)$ no-gzip dont-vary
	<IfModule mod_headers.c>
		Header append Vary User-Agent

If your website is not very image heavy it can speed up to 60% of bandwidth usage.

3. Optimize HTML

Use Google Webmaster to see which page takes more time and to load and see if you can reduce the size of your HTML code on those pages. Excessive use of tables or even unwanted nested tables just adds to the size of the page.

4. Cache Static Content

If you are into web development you would know the issues with caching but it is not all the sad things that caching can do. If your website images are cached on user’s browser he may not need to download them again and again saving you not only lot of bandwidth but this also mean that his each subsequent page visits are faster and quicker for the user.

In Apache, you can just add the following lines and this would mean your images, style sheets and JavaScript code are stored on user PC for 30 days before downloading again.

<IfModule mod_expires.c>
	ExpiresActive On
	ExpiresByType image/gif A2592000
	ExpiresByType image/png A2592000
	ExpiresByType image/jpg A2592000
	ExpiresByType image/jpeg A2592000
	ExpiresByType text/css A2592000 
	ExpiresByType text/js A2592000 

5. Optimizing Images

Images are one of the main reasons why your pages takes more time to load and so there are more than one way to optimize your images. You can have the same image in 2 different sizes. Try to convert your images to the lowest possible size. This would mean that with the same user experience you actually speed up your pages.

6. Use Image Sprites

Combining lot of small images into a single large image and then placing the same image with the CSS background-position property can save lot of web server requests, file IO and even rendering of lot of small files. Many large websites does this like

Or even Addthis

7. Cookieless domain

Any query to just download a static content is appended with many header data. Large websites uses different domain (i.gstatic.com by Google) for serving static content and the only reason I can think off is they serve static content from an external domain which does not send header and especially cookies for the content, saving lot of unwanted header data transfer.

8. Avoid Flash

When you use too many flash widgets on your web page it slows down the page considerably. So keep away from flash to the extent possible.

9. Remove un-wanted Gadgets

I see many sites and specially blogs have too many gadgets like temperature, date, map and other such frills and if you think they are not used by your users to the extent you want them to be using it, it’s better to remove them from your page.

10. Control Ads

Last but not the least is your ads. Apply the 80/20 rule. 80% of ads generate 20% of revenue and 20% of ads generate 80% of the revenue. Find the right balance between lesser ads with maximum possible revenue. See each ad unit on your page and see how they have performed for last 3 months and see if some ads just generated $0.05 for last 3 months and flush them out. Apart from that you can also see how a rich media ad works and if they are not very different from text ads, opt for text ads.



9 Ways to Remain Safe on WWW

9 Ways to Remain Safe on WWW




Points to remember to stay safe and secure on the WWW.

1. Install a good antivirus/IDS

There are many sites on the net spreading Trojans, viruses and all kind of dirty stuff! If you are without a Anti-Virus, then it is most likely you will get infected within a day or so!

2. Update your OS at least once in 3 days

Never Ever avoid updating your OS no matter if its Linux, Windows , Mac etc. There are exploits released almost every day and if you are without updates then it’s a invite to Hackers.

3. Never blindly click any links

Don’t even trust Google , If the link is given to you from a untrusted location it may point to a Trojan ,Virus , Phished Page , etc..

4. Don’t use same passwords on multiple sites

Using a same password on multiple sites is the worst thing common users do while surfing the web. Same passwords on multiple sites are an easy way for hackers to get access to your other accounts on the web.

5. Avoid registrations when you can do things without it

Most of the people of the net are just unaware of the fact that registering on multiple sites can affect their privacy and can lead to further problems. Eg :- If i hacked a website where you are registered and i find some of your details from the site’s database , These details can help me crack your password on other sites and eventually leading to further attacks.

6. Scan the website before visiting

If your friend sent you a link and you want to test it if it’s secure to visit that site , then you can scan the website for malicious files in some online scanners , (It just take a minute!)

7. Use strong passwords

Powerful Passwords refer to a password which at least contains a letter(Small as well as Capital) , number , Special Character.
Use of keywords like your birth date, name, username etc is a big NO.

8. Don’t trust anybody you don’t know

There are bad guys whole over the World Wide Web (especially on social networking sites), Hunting for victims, they ask for your sensitive information leading to successful exploitation of your account. Read more about Social Engineering for more info

9. Always use a secure browser

Client side attacks are a common way to get access to your machine, today most of the attack are undetectable by AV’s and IDS. Till date I find Mozilla Firefox to be the most secure and Internet Explorer to be the most weak.




How Anti-Viruses Works???

Anti-Virus is a software or a program that can scan your files and data in your computer prevent you from firmwares and viruses…

How Does it works

Anti-Virus uses 2 different techniques to accomplish its tasks :-

  1. Examining Files and comparing its signature/structure to that of viruses present in a database or a text file…This is called a virus-dictionary..
  2. Identifying some suspicious behavior from any Program or Software sitting on the system

Virus-dictionary Method

In a Virus-dictionary Method a Anti-Virus starts by examining a file and checking up the dictionary of known viruses…

Every Binary/ELF/.exe has its own signature if they have different functionality…
Actually by signature we means some data in the bin file..This is a set of opcodes which the computer understands..These are different in every unique program..

When the Anti-Virus gets the signature of the file it then checks for the same signature in the dictionary of known-viruses(reported signatures) if it matches any signature in the dictionary then it is reported as a virus and the required task is performed(Dis-infection , removal ,etc etc..)

For this method to be successful , The virus-dictionary needs to be updated as a new virus-signature is reported.

This Method is quite common in most of the anti-viruses out there but it is not so successful now as its really easy to bypass this protection by using binders (These are the program that binds one program to another) , packers (Packs the signature , simply compresses the opcodes and make it difficult to detect) , encoders (These are the main cause of concern for the Anti-Virus developers out there as its quite a powerful approach , the encoders change the opcodes to something similar which provides the same functionality…It drastically changes the bin signatures and makes it almost undetectable..)

Another con of this Method is that it takes a lot of time and system resources to scan and compare all the files sitting on our system..

The Suspicious – Behaviors Method

In this method the anti-virus simply check for some suspicious – behavior happening on the system.. For checking this the anti-virus today has many modules like :-

  1. Network Traffic Monitors
  2. System Files Monitors
  3. Process Monitors etc etc..

Network Traffic Monitors

Network Traffic Monitors simply monitors the incoming and ongoing network traffic from the system to other systems or the internet…

For eg :-

If there is a trojan sitting on the system..It will certainly listen for the attackers call ..As it receives the attackers call (in the form of a TCP , UDP etc packets) It simply send down the data to the attacker system (most of the trojans) This fluctuates the network traffic and Anti-Virus catches the trojan and performs the required task..

System Files Monitors

The System files Monitors simply checks for the files sitting on the system ..

Eg :-

If there is a virus sitting on a system and it checks for some system files and tries to dlete them then this will Report as a suspicious behaviour to the anti-virus..Then the anti-virus performs the required task..

Process Monitors

The Process Monitors check the process tree of the system and checks if there are some hidden programs running..If it finds something suspicious it reports the anti-virus core and then the required task is performed..

Eg :-

There is a key-logger sitting on the system. Most of the key-loggers have hidden processes and simply reads the key-strokes a user makes..This would be undetectable without the use of Process Monitors..

Actually these were only the features on a basic anti-virus Most of the anti-virus today have Millions of protection systems and features and its not in the scope of this article..

BitTorrent – Tips & Tricks

BitTorrent – Tips & Tricks

BitTorrent - Tips & Tricks


uTorrent is currently the smallest, lightest and most feature packed BitTorrent client available. With a file size of barely a megabyte, it’s perfect for even low powered computers like netbooks and there are some versions available for mobile devices as well that allow you to connect to your home PC and check the status of your downloads. It’s even surpassed the popularity of some previous famous torrent clients like Azureus (now called Vuze). Many first time users of uTorrent may immediately hate it because of the slow speeds or the torrents simply refuse to connect to any seeders or peers. There’s a simple reason behind that; unlike a P2P client like say LimeWire where everything is pre-configured, you need to do a little tweaking to get the best out of uTorrent and that’s exactly what we’ll be discussing today. Other than that, we’ll also share some very interesting features uTorrent has to offer which may go unnoticed for many simply because not everyone is an inquisitive geek.


Solving the NAT Problem


You should have a little green circle here for best results

When you install uTorrent, the application automatically adds an exception to Windows Firewall so the incoming traffic is not blocked. Despite this, you may still get a little exclamation or a red circle in the bottom right corner of uTorrent and if it continues to remain then you may have a NAT (Network Address Translation) problem. Most ISPs (except a few) tend to block P2P traffic which means most of the ports other than the ones used for the HTTP protocol are blocked. What you’re looking for is a green circle with a little tick mark which means your PC is able to receive incoming connections.

There are two ways around this. The first is the simplest way, by default; UPnP is enabled in uTorrent which automatically maps the port you’ve currently assigned with the router. If the router has UPnP support then make sure it’s enabled. For this, you’ll have to enter the router settings and navigate to that section. Since each router has different features and organizational structure, it’s best if you check the manual that came with it or the site. If you’re trying this at work then you’ll have to check with your network administrator for this although I doubt he’ll be of much help unless he’s already busy downloading quietly.

Simply enter the IP of your PC and the port number in both start and end fields and your set

In case you don’t have a router at home or the UPnP trick is still not working, the second one is a sure fix. The first thing you need to do is pick a port number, any random number generated by uTorrent is fine. Next, check if the port is open by going to Options>Setup Guide. Here uncheck the first box ‘Bandwidth’ and only keep the second one (Network) checked. The default port number will already be in there. Click the button ‘Run Tests’ and it will check if the port is open. If it still reports that the port is blocked then you’ll need to open the port in either you modem or router. Most modems supplied by your ISP will have a feature called ‘Virtual Server’. If you aren’t using a modem and just a router then you should find that option over there as well. To know how to access this ‘Virtual Server’ section, I strongly recommend PortForward.com as it has detailed instructions on how to setup port forwarding on virtually every modem/router in the market. Once this is set, just restart uTorrent and you should immediately see a green circle telling you everything’s ok.



Getting the maximum speed from your Internet connection

Even though your NAT problem is fixed, you may find the speeds aren’t really up to the mark. Let’s say you have a 1Mbps line at home, the download speed that you can actually get is 120kBps but somehow you never get beyond 20kBps. This is because your download and upload limit in uTorrent is set to unlimited by default. In India, most Internet plans are capped at a low upload rate despite of having a high download rate. Think of the upload and download rate as lanes, if both are set to unlimited, uTorrent will automatically divide the bandwidth and give each lane equal preference so automatically your download speeds are halved.

The trick to getting the most out of your internet connection is to cap the upload speed in uTorrent. You can do this by going into Options>Preferences> Bandwidth or you can simply right click the status at the bottom and select the upload speed. After a lot of trial and error, I’ve found 9-10kBps to be the sweet spot at my home but it’s not a hard and fast rule. You can experiment a bit and try different combinations to see which works best for your connection. Even after setting that if you’re still getting slow speeds then make sure that torrent has enough seeders or try a different one. There are time when a torrent may show you there are thousands of seeders but you still get shitty speeds which could mean that the people you are connected to are uploading at a slow rate in which case there’s nothing you can do about it.



Schedule Downloads

Not everyone has an unlimited data plan, so for those who rely on the night unlimited plan, uTorrent’s scheduling function comes in really handy. Head over to Options>Preferences>Scheduler and check Enable Scheduler. Now let’s take a simple scenario, I’m on a night unlimited plan which means from 12AM to 8AM, I’m not charged for using the Internet. Each square represents an hour during the day, so from Monday to Saturday, I have marked all the squares white from 8AM to 12AM which means uTorrent will automatically stop any uploads or downloads during this time. Assuming Sundays, you get the entire day to download for free, you can mark everything green. This way, uTorrent will automatically start and stop downloading without the need for your intervention. If you find the browsing speeds drop then you can mark some hours of the day as light green so the bandwidth is limited and you can surf the net properly.



Use Auto-Shutdown to Save Power

A simple but very handy feature which should be used by everyone. You can choose to place the PC on Standby, Hibernate, shutdown when the downloads complete or simply quit the application so that the bandwidth is freed up. This would save you some power as well instead of the PC just remaining on doing nothing.



Maintain a good share ratio

When it comes to torrents, sharing is caring. It’s a good practice to seed the file you’ve already downloaded for sometime at least so that the others have a fair chance of downloading the file. It’s also a good habit since some private torrent sites like Demonoid.com keep a track of your download and upload ratio. Here’s the thing though, once a file is downloaded, uTorrent automatically starts seeding. At some point, you would like to stop seeding the file simply because it’s old or it may be hogging all the upload slots as compared to a newer file that’s being seeded. In this case go the Queuing section in Preferences and instruct uTorrent to stop seeding a file once it has achieved a ratio of 1.0. By default, uTorrent will stop sharing that file once the share ratio reaches 150 percent.


Take advantage of the new Apps feature

The new version of uTorrent includes a new App section which gives you access to more content right in uTorrent. For instance the TED app lets you download all Ted talks or VLC which lets you playback any music or video file you’ve downloaded.

Google’s New Navigation Bar, Publicly Available

  • Google rolls out New Navigation Bar

  • Does away with underlined links and adds more color to the bar

The new navigation bar is slowly rolled out to all Google users. After more than 6 months of testing, the new navigation bar removes the clutter by grouping extraneous links in a menu inspired by Google Chrome. It also removes link underlining and replaces it with a colored bar. There’s more spacing between the links, so the new navigation bar works better on a touchscreen device.


Another change is that Google shows your name instead of your email address. For some reason, Google doesn’t link to the Google Profile and makes it more difficult to switch to a different account if you use multiple sign-in or Gmail delegation. Now you need to click “Switch account” to see the list of accounts you can use.

Unfortunately, Google didn’t manage to add the bar to all its services, so you’ll only see it if you use Google Web Search, Google Image Search, Google Realtime Search, Google Maps and Gmail.
