While its a shame Duarte isn't sticking around to see things through with Palm, this is a major blow for HP and paints a brighter future for Android. Duarte has worked in the past with members of the current Android team when he was the director of design for the phone maker Danger, which like webOS provided a slick user interface for their phone called the Sidekick. In an odd turn of events, Danger was co-founded by Andy Rubin, who coincidentally left Danger to start Android Inc. in 2003. Since then Android was sold to Google, Rubin became Vice President of engineering, and Duarte rejoined his former colleagues at Android.
Currently Android phones are known for sacrificing aesthetic design and a pretty UI for more functionality and improved customization features. Gingerbread, the next version of Android, is already in the works and expected to release at the end of the year. While Duarte may not have much of an influence in steering Gingerbread, expect to see his full visual influence come into play on the following versions of Android.

1. Protect Your Web Browser
The most direct line of attack between the internet and your computer is the browser installed on the PC. Flaws found in browsers are one of the oldest techniques that online criminals have been using. These browser vulnerabilities download malware onto computers using hidden download methods that users will never notice and can't possibly know exist. Internet Explorer and Mozilla Firefox are the most targeted browsers due to the fact that they have been the most widely available and consequently are the most popular among users. Be sure to download updates for your browser regularly and you can be relatively sure that you are surfing safely.
However, your computer can still be exposed to malware in the time between a discovered vulnerability and the implemented security fix. In cases such as these, it is recommended that you use security software in conjunction with regular browser updates, especially if you are a Windows XP user. It would also help to use a more obscure browser such as opera or chrome, both of which are newer browsers on the market and don't have the same popularity as Firefox and IE.
2. Get Adobe Updates
Most consumers are familiar with Adobe Reader, which opens and reads PDF files, and Adobe’s Flash Player for its prominence in online web games. In recent years, a virtual epidemic of attacks has flooded Adobe attempting to exploit their security flaws. Nearly half of these attacks today come hidden in PDF files which will infect a computer as soon as its opened. The beauty of this kind of infection method is that no matter what kind of browser you might be using, its almost a sure thing that you're using Adobe Reader and Adobe Flash Player. The good news is that the majority of people getting infected via Adobe are running old, non-updated versions of their software, much of which has glaring security holes. Nowadays Adobe attempts to update automatically and it is as simple as following a few simple steps. If you would like to make sure your software is up to date, all you have to do is manually update Adobe.
To update Reader, open the application and then select the “Help” tab and click “Check for Updates” from the menu bar. After a few moments Adobe will determine if your software is up to date and if not it will prompt you to download the latest version. Since April 2010, Windows users have been able to choose to get future updates automatically without additional prompts by clicking “Edit”, then “Preferences”, then selecting “Updater” from the list and checking “Automatically install updates.” Mac users have a similar option available to them but Apple will require that they enter their password each time an update is installed. Adobe has elected not to allow silent and automatic updates due to many people being adverse to them.
3. Beware Malicious Ads
An increasingly popular way to get attacks onto trusted websites is to slip them directly into advertisements, usually by tricking smaller advertising networks. This practice has come to be known as Malvertising, which typically exploits software vulnerabilities or sends deceptive and harmful pop-up messages to the user. The most well known version of Malvertising, and one you've probably personally encountered, involves an alert that a malicious virus has been found on the computer, followed by urgent messages to buy the necessary software to remove it. Of course, there really is no harmful virus and the security software, called scareware, is nothing more than fake. This method is simply a ploy to get credit card numbers and a few quick bucks at the expense of a gullible person who believes the message they are seeing is a genuine notification from their system. Currently scareware accounts for half of all malware delivered in advertisements which has increased five times since last year.
Closing the pop-up or killing the browser will usually end the episode, but if you encounter this scam, be sure to check your PC with trusted security software or with Microsoft’s Security Essentials. If you are unlucky enough to have picked up a nasty virus, don't sweat it. Microsoft cleaned scareware from 7.8 million PCs in the second half of 2009, up 47 percent from the 5.3 million in the first half, the company said. My personal favorite for eliminating threats garnered from the web is called Malware Bytes.
4. Poisoned Search Results
There is an online phenomenon on the web called Search Engine Optimization (SEO) which is a technique that raises websites to the top of search engines based on keywords alone. Online criminals are also using this technique to manipulate search engines results into placing malicious sites toward the top of results pages for popular keywords. Typically these malicious sites embed popular keyword to try to distribute scareware to those unlucky enough to visit. Luckily search engines like Google and Microsoft’s Bing are doing their best to detect malicious sites and remove them entirely from their indexes. There are free tools available online such as McAfee’s SiteAdvisor and the Firefox add-on called Web of Trust which can warn you about potentially dangerous links.
5. Antisocial Media
Attackers also use e-mail, instant messaging, blog comments and social networks like Facebook and Twitter to trick people into visiting their websites or downloading malware. It's always better to be safe rather than sorry when dealing with suspicious messages or friend requests, especially in today's day and age. Phishers are trying to steal your login information so they can infiltrate other accounts, impersonate you to try to scam others out of money, and of course gather personal information about you and your friends.
One of the most rampant variants of these AntiSocial Media attacks have come from the Koobface worm and its cousins which have been taking aim at users of Facebook and other social sites for more than a year. The attack usually begins with the promise of a hilarious and never before seen video which prompts you to download a fake multimedia-player codec which is required to view the video. If you do happen to download this codec, your PC will become infected with malware and assuredly become part of a botnet which spews spam and malware across the four corners of the Internet.
Despite all these great tips for keeping you safe on the net, the most important aspect involved in keeping your computer safe from malware is to have a healthy dose of suspicion when browsing. Online criminals are using increasingly sophisticated methods to prey on the unsuspecting and your best defense on the web may just be your gut instinct.

Most screens look fine during the morning hours and day because they’re made to be BRIGHT like the outside sun. However, during the evenings at 10PM, or even 4AM for that matter, you definitely shouldn't be looking at anything that resembles the sun. Ever notice that when you come back to your monitor after dark, or even just as dusk is falling, they tend to blind your eyes and make you reach for the brightness controls? F.lux fixes all this by adjusting your computer's display to adapt to the time of day. It will become warm colored at night and during the day take on the color of sunlight. As someone who has battled with insomnia on more than one occasion, it's definitely nice to know I won't turn on my monitor only to have my retinas seared.
The basic principles behind the F.lux program involve adjusting your monitor based on color temperatures. The term color temperature is a way to numerically describe how much red or blue light is illuminating a room. Color temperature is measured in Kelvins and is used to describe every kind of light you use and buy. Warm colored light sources are described in lower degrees kelving while cool light is higher up the spectrum. A candle which gives off a red-orange light has a color temperature of approximately 1800K while a bright sunny day may be around 6000K. A cloudy day will cause the sunlight that penetrates to have a more blue color and may have a color temperature around 7000K. If you're wondering what the color temperature of your monitor is, consider that most LCD's are defaulted to 6500K while CRT's may have an even higher color temperature.
Keep in mind that this program is not designed for use during advanced color work such as graphical design but it will be perfectly fine for regular use. I personally don't have a problem at all with the color when I play video games at night. If you have a problem with your screen looking much too yellow at night, try adjusting the color temperature sliders under the settings tab. I personally have the Daytime setting cranked all the way up with my night temperature sitting at 4200K near the Flourescent setting. What I like best about F.lux is that once you set it up you will never have to think about it again. Its all automatic.

A properly calibrated television could end up looking better than a factory defaulted TV of nearly twice the price. Blu-ray content especially is sensitive to calibration and you will be absolutely surprised at the differences. My friend had just bought a High Definition LCD TV Monitor and we decided to test out the waters by watching Pan's Labyrinth on Blu Ray. I thought the picture quality was superb and was congratulating him on purchasing such a sweet TV. That's when he decided to open up all the settings on his TV and he actually sat down to calibrate the TV while I watched. He asked my opinion on a few setting since he is partially colorblind but it was easy enough to get through. We tossed in The Dark Night on Blu Ray immediately after and my jaw dropped at how much better the picture looked. I was truly stunned at the image quality. I could count the hairs on Christian Bales five o clock shadow and was almost blinded when the picture would switch from dark scenes to brighter ones. I felt for the first time that I had seen what the Blu Ray technology could actually do and it sent chills down my spine.
So how exactly do you go about calibrating a High Definition TV? The process is quite simple and is often ignored in the manufacturers instruction manual. The first and most important step you should take when calibrating your TV is to mimic the ambient lighting in the room that you normally watch your movies in. For example, if you find yourself watching your TV mostly in the middle of the day open the curtains and let in some light. Otherwise, if you watch a lot of movies in the late evenings, try dimming the lights and closing the curtains.
Brightness or black level is one of the most important settings on your TV. Your goal when calibrating this setting is to try and lower the brightness right down until blacks look deep on all levels of darkness. If there is a loss in detail when viewing varying levels of dark you don't have your setting correct. When tweaking this setting its a good idea to find an image or movie with a great dynamic range. Something that displays both dark shadows with clean and bright scenes such as The Dark Night.
Once you are done with your black levels the next setting you will be moving onto will be your television's contrast settings which may also be called white level. Basically you want to raise the contrast until whites get as bright as possible while still being crisp and not blurred in any way. A poor contrast ratio will have a negative effect on the color quality which may cause your picture to look washed out or like there's a transparent black sheet draped over the TV. Adjusting contrast ratios can prove difficult as any changes you make will affect the brightness levels previously mentioned.
Next up is sharpness. Sharpness could more accurately be called "artificial edge enhancement" and generally only improves the aesthetics of lower-quality signals like standard cable and satellite programs. Increasing the sharpness may give you the illusion that you're getting more detail, but the end result is definitely not a more accurate picture. Too high of a sharpness setting will often creates halos around the edges of objects onscreen and create hard looking edges. Take into consideration that most movies already have this edge-enhancement filter applied during mastering so as a general rule you can leave sharpness very low or even at zero as sharpness is not needed for HD sources.
Color levels are perhaps the most difficult and subjective setting you will need to tweak on your TV as these color changes will affect your previously tweaked settings. The best thing to do with colour levels is essentially do it by eye. Fortunately, factory settings for color are usually close to where they should be. You want to avoid a picture where it looks like everyone is sunburned or some of the colors have been amplified to an extreme. Some of these color level settings are called tint, hue, and color temperature. Remember, you simply want to try and balance out the colors as best as you can without negatively affecting your previous adjustments. If you're used to watching TV with a high contrast and brightness setting you may find that your picture seems a bit dull. If so, try living with the new settings for a few days before changing them back. Your eyes may not have gotten used to a more naturally balanced picture and we as humans typically avoid change.
If you want to take much of the guesswork out of manually adjusting your TV's settings and get great results at the same time, you may consider purchasing a calibration DVD. These discs include test patterns and specifically created videos and scenes that make it easy to match your TV's settings to broadcasting standards. If you want to be 100% sure you're getting the best possible picture your TV can deliver, consider hiring a certified professional to calibrate your HDTV. These experts will be armed with specialized test equipment and an extended knowledge of the inside of your TV and more advanced settings which should definitely be left up to the experts.

"What do we think the next big wave of opportunities are?" Verizon Wireless CEO Lowell McAdam said in the interview. "We're working on tablets together, for example. We're looking at all the things Google has in its archives that we could put on a tablet to make it a great experience."
The move certainly strengthens the relationship between Verizon and Google which was forged last fall when the two announced a multi-year collaboration on devices and services. However, it remains to be seen how Apple will respond to the news of a new tablet powered by Google, which already competes with Apple in wireless software and mobile advertising. Odds are Apple is a little less than pleased and it will be interesting to see how they respond to Verizon's request to carry the iPhone on their network. Perhaps this announcement is merely a ploy to give Verizon more leverage in negotiations with Apple or perhaps Apple has already denied Verizon access to their iPhone.
Regardless, an Android tablet on Verizon's network is not entirely surprising. At the Consumer Electronics Show last January Motorola demonstrated a prototype Android tablet running on Verizon's upcoming LTE network. It was also noted in the demonstration that if the tablet was commercialized and produced, the device could be released for sale as early as fall of this year. Verizon has already admitted to being “handicapped” by its CDMA network but McAdam promised that the new devices would be available on the company’s new LTE 4G network, which arrives early next year.
As of right now, Verizon and Google are in it together for the long haul and it looks like Apple will be facing much stiffer competition with the tablet than it ever saw in the iPhone and iPod markets. Now that Android tablets have been confirmed and an HP/Palm tablet all but unannounced, there will undoubtedly be an all-out tablet war. Right now Apple has the very distinct advantage seeing as they have already released a matured iPad and analysts estimate that it will take one to two years for competitors to reach the same functionality. Lets just hope that we as consumers see some benefit from this tablet war.

If you examine the evolution of the smartphone—particularly after the release of the first iPhone which paved the way for the smartphone industry—it becomes clear that the devices are really just small PCs. They require processors, ram, and other hardware just like a PC and at the same time they require operating system to bring all that hardware together for a smooth platform. Dell was perhaps one of the first to notice this PC "trend" and now the company is coming out with Dell-branded smartphones.
HP, on the other hand, allowed its Windows Mobile-powered iPaq line to stagnate while they waited for Microsoft to roll out a new version of its mobile OS. As HP continued to wait for Microsoft and the iPaq line further deteriorated, Apple, Google, RIM, and many others have bulked up their rosters of smartphones leaving HP trailing in the dust still waiting on Microsoft. It's important to note that Apple and Google (Android) aren't just offering great smartphones, but rather an all-in-one phone solution including hardware, software, and services.
Clearly HP was missing something despite their ability to produce great hardware and provided great services. So far HP has been forced to use currently available operating systems which has effectively tied HP's future to whoevers' operation system they used. Whether it was Windows Phone 7 or Android, Microsoft or Google would have controlled their destiny.
With the Palm acquisition, HP is finally in a position to control its own mobile destiny. With webOS, HP gets an operating system that fully spans mobile communication and the Web while no longer having to rely on Microsoft or Google to provide the OS. This merger successfully puts HP's foot in the door for smartphones, tablets, and netbooks. HP currently plans to invest well over $200 million into Palm R&D while also investing heavily in third-party software development for the webOS platform. Palm's OS gives HP the ability to unite Web apps with mobile apps in real-time on mobile platforms just like the iPhone.
However there is a chance that HP's plan will be nothing more than a huge flop. Simply put, HP wants what Apple has. A single operating system, which it completely controls, at the heart of all of its consumer electronics -- phones, tablets, netbooks, lightweight PCs, digital cameras, televisions, etc. The problem lies with the fact that WebOS is already considered a failed platform. Despite its nice user interface and a few technical qualities, consumers haven't found any justification to buy Palm devices instead of Apple, Android, or even Microsoft devices. And, more importantly, developers haven't found any incentive to develop applications for WebOS.
Without any unique apps there would be absolutely no reason to have a unique platform. All the while, Android and Apple continue to fade away into the distance with crowds of people behind them while HP is still trying to get their game straight.
Hopefully this merger will become a success with HP becoming a mobile powerhouse over the next few years but only time will tell.
