InvisibleSHIELD for the iPhone Review

invsibleshield1.jpgThe problem with iPhone cases is that they cover up the beautiful design of the iPhone. But if you don’t put a case on your iphone and you end up damaging it, you’ll never forgive yourself either. Think of the InvisibleSHIELD as a happy medium. Kind of like the emperor’s clothing, the InvisibleSHIELD is designed to protect your iPhone without covering up its lovely curves.

Initially, I was a little skeptical about using the InvisibleSHIELD on the face of the iPhone because I was worried that it would interfere with the sensitivity of the iPhone. Fortunately, it hasn’t interfered at all with the iPhone’s usability. The package included a piece that covers the face of the iPhone, and the back of the iPhone. However the piece for the back of the iPhone doesn’t wrap around far enough to cover the metal edges on the iPhone’s face. I find that a little disappointing since, since I think that the metal edges are the most delicate area on the iPhone and mine have already been getting a little scuffed up from use. The InvisibleSHIELD also claims to be scratch proof. Admittedly, I am to chicken to test that theory out on my precious, however I’ve been carrying it around for a couple of days and it has kept my iPhone safe and sound so far.

Applying the invisibleSHIELD was simple enough, though it did take concentration in order to take some effort to make sure that no air bubbles got in. A spray on solution is included with shield that makes the invisibleSHIELD movable on the iPhone’s surface, so that you can align it as perfectly as possible without much hassle. I succeeded in aligning the front and back piece of the invisibleSHIELD pretty well, minus a bubble that I couldn’t manage to get rid of on the back side.

Overall, the invisibleSHIELD has proved to be a great way to protect your iPhone and I believe that the $24.95 price tag is a fair one for it, especially since they include a lifetime guarantee. My only gripe is that it doesn’t cover the iPhone completely. Also, it’s important to keep in mind that while the InvisibleSHIELD is strong, it’s not strong enough to protect your iphone from the impact of a bad fall. The InvisibleSHIELD is also available for other iPod models and other popular cell phones and gadgets.

Conclusion:

The Good:
Protects iPod without covering up it’s good looks

The bad:
Doesn’t cover the iPhone completely

IFO 3000 Levitating Objects for Your Desk

ifo3000.jpg

Call it magic, we’ll call it the power of magnetic fields, but the IFO 3000 can make objects float mid-air. A special microprocessor inside the IFO controls the magnetic field used to hold and balance an object so that it levitates. You can choose from a range of accessories to make float in the IFO 3000, including a color changing night light, a picture frame, a globe, a mini cooper, or a LCD Alarm Clock that also displays date and temperature. It’s killing us that they can make something like this, yet it’s been 20 years since Back to the Future was in theaters and we still don’t have hover boards. The IFO 3000 retails for £54.50, with accessories costing about £12.95.

Three "Centrino Duo" Laptops For Students

Admission season is upon us and with a lot of new students all set to enter MBA/ IIM/ Engineering colleges, one thing they need to purchase to allow them to work seamlessly, is a laptop. A laptop for a student is a necessity now, as most campuses now days have Wi-Fi. This allows them to function from virtually any corner and when one looks at the rather cramped quarters most universities have, a laptop becomes an essential requirement and not a luxury.

This brings us to the real problem. Intel recently launched their new platform “Santa Rosa”, which talks about significant performance upgrades, better battery life and greater compatibility with Windows Vista. Now this is where the problem starts. Quite a few companies have announced a rash of products without really phasing out their previous Core 2 Duo lines. Most manufacturers now offer both generations of products leading to confusion among users as what to buy. While choice for consumers is always a good thing, most manufacturers just don’t take the trouble of having a coherent product naming scheme that differentiates on product lines and makes the choice easier for the consumer.

So we decided to go through the various product launches and pick out 3 laptops that are based on the new “Centrino Duo” aka “Santa Rosa”.

Dell Inspiron 1520



It is rare to contemplate any kind of roundup, without a single Dell product in its ranks. The newly introduced Inspiron 1520 is a typical Dell product, that offers a range of new “Merom” processors ranging from the T7100 upwards, has a standard of 1 GB RAM, storage space of 120 GB, a choice of Nvidia’s graphical chipsets (8400 GT and 8600 GT), 802.11n support and a 15.4 inch screen with a native resolution of 1280x800. Apart from these basic specifications, it is the range of customization that Dell offers which makes this laptop interesting. Not only can one upgrade to an HD ready resolution of 1680x1050, it offers the choice of adding in a webcam and a Blu-Ray drive. With prices starting at Rs. 58,000, this is ideally our first choice for anyone looking to purchase a solid and a dependable future-ready product.

HP Pavilion dv2519TU

Having recently taken over from Dell the position of the world’s largest PC/Laptop manufacturer, HP continues to grow from strength to strength. One look at the DV2519 TU and it’s not difficult to guess why. For starters, it packs in a decent choice of processors ranging from the T5250 upwards to the T7100, has 1GB of DDR2 667MHz RAM, a 160GB SATA HDD and a Lightscribe Super Multi DVD Writer (+/-R +/-RW) with DL support. For its graphics it uses Intel’s GMA X3100 chipset, which is Windows Vista Premium ready. For its connectivity the laptop also packs in Wi-Fi 802.11n support, Gigabit Lan , a 5-in-1 Multicard reader and a 56k modem. HP recognizing the need for more security at a consumer level, has recently started building in security features into their laptops. This fact is amply illustrated by the fact that this laptop ships with a security fingerprint scanner.

The prices for this laptop start at Rs. 57,000 and make it an excellent alternative to Dell’s offering.


Acer 6292

Acer while not being as big as the other two brands in this roundup has built up an excellent reputation for offering solid VFM products. The 6292 reviewed by us is one such product. It offers a powerful Core 2 Duo T7100 processor, 1 GB of DDR 2 667 RAM, a 12.1 inch screen with a native resolution of 1280x800, X3100 Windows Vista ready graphics chipset, 160 GB of storage and excellent battery life of nearly 3 hrs under full stress.

The price for this powerful machine starts at Rs. 69,000. For a more detailed link please head on over here.

Home » Features » Portable MP3s & Gizmos » 5 Most Annoying Features in MP3 Players

Back in those days when the dearest thing to me was my Sony Walkman, the single biggest annoyance happened to be the GSM signals interfering with the playback. This invariable happened due to the fact that headphones then, weren't equipped to handle GSM interference. But this didn’t stop me from cursing people for being constantly over the phone.

These days, however, the reasons have changed, and I still curse. Although the reasons that annoy me have changed. After having used and tested scores of mp3 players, I realized that even though we have moved on to achieve a certain respectable level of technological integrity, we still lack in keeping our act together. In my opinion the only thing that MP3 players should differ from each other in is the sound. Why create a niche by wasting time building 'wild' keys and ‘innovative’ designs (hope you catch the sarcasm) when all they do is hurt.

Low Volume level
Now this one, you have to agree with me. What’s the point of making a good looking and plush product when the volume can’t even beat the racket on the road. Despite, what they call it, a cutthroat competition, companies make products with little room to maneuver with regards to the volume output.

When it comes to selecting the right player, apart from the quality, I always look at the volume output. I’m not getting into wave frequencies or sound nitty-gritties. All I’m saying is that when you stay in a noisy city like ours, and (like me) if you depend on your music to save yourself from the insanity, then a player with low volume output will just put you off.


Another problem with some players in the market is that the sound begins to distort the moment the volume is pumped up. I know a certain sect of people who don’t mind, or in some cases can’t make out the difference. For true music connoisseurs, however, this is a big downer. By far, some of the Chinese players that have been on sale in and around the city are known to have this problem.

Also, I will just add that I’m talking about low output levels in context of high bit-rate songs. It’s always nice to listen to songs that are properly ripped. You might notice that while playing certain songs the sound just skyrockets. For this, always make sure you normalize the volume on all songs. Also, you can use software like ‘mp3gain ’ to adjust peak normalization.

Bad set of earphones
Earphones alone can either make or break your listening experience. Of course, what may seem bad is a matter of perception and the design of one’s ear. This is exactly why I think while packing a set of earphones with the player, companies should keep the masses in mind before dishing out products that either keep falling off, or starts hurting your ear.


Apart from ergonomics, many players in the market are known to pack bad earphones with regards to quality. I know it’s the manufacturers prerogative to make stylish and innovative earphones. But not by compromising on people’s comfort level and want for good products. This is exactly why most people have to upgrade their set of earphones after buying the player. Players like Transcend T-sonic 610, Turbolinux Wizpy and even the Cowon A2 have below average earphones. While, some in this list come with bad designs, many here have a below average quality.

What you need, instead, is the good ol' super-aural design to come back in fashion. These headphones are by far is the best value for money. The bass control as well as the stereo dynamics that these can handle is overwhelming. For people who are in love with earphones, would appreciate those in-ear ones that work on noise-isolation technology.

Bad Design
Trust me when I say sleek and slim is in. Keeping this in mind, every product is moving from small to smaller. This goes without saying that everyone prefers a tiny player that slips into the pocket without showing any bulge. However, I certainly don’t appreciate oddly shaped keys (odd is fine, it’s only when they get uncomfortable to use I have a problem) or/and unevenly placed keys. Perfect examples of small sized players with easy-to-use keys would be the Panasonic SV-MP020A, iPod shuffle, Creative MuVo series etc.

Another annoying thing is to see mp3 players without a screen. iPod shuffle is one! I know it is meant for people with a fetish to shuffle songs. But I would love to see what I'm listening to, and it always rocks to have nice interface to arrange, rearrange songs, select presets etc. Shuffle doesn't allow any of that. And by not including, it's not like the prices are low either. You are still paying a premium than most of the players that cost less in the market. What the heck!!

Bad preset options
Whenever you pick a player to scrutinize at any shop, I suggest you check out the pre-loaded song with respect to each and every preset option. In fact, I go so far as to check the usability of EQ settings. I prefer using my own settings, however, when in a hurry it’s your right to expect the presets to perform up to the mark. That good presets come only with high-end products is a misconception. I know some cheap players like the iPod Nano and the Cowon A2 to be the cheapest in the category and still provide some killer preset settings.


Also i hate useless 5-band equalizers that some players dish out. So working on manual settings can prove to be a big problem. You dont want to end up with something that sounds like the loud treble rickshaw deck. While I'm at this, I'll also suggest you be wary of players with confusing UI. You will be stuck figuring out where to find what!!

Lack of expandable memory

Now this is something that is not very common. It beats me how companies have failed to standardize this. When you are making long distance trips, chances are you may have heard all the songs back to back twice. This is when you will wish your player had an option to increase the memory. It's not like players don't come with this option. The Wespro WK512S, the SanDisk Sansa series, iRiver clix etc. have this option, and they don't even come with a premium for this. In fact, if the Wespro player comes for less the Rs. 2,000.

You know the list doesn't end here. There's DRM file compatibilty issues, external battery etc. You can discuss all this and more in our forums.

Apple Plans Cheaper, Nano-based Phone

Apple Inc. plans to launch a cheaper version of the iPhone in the fourth quarter that could be based on the ultra-slim iPod Nano music player, according to a JP Morgan report.


Kevin Chang, a JP Morgan analyst based in Taiwan, cited people in the supply channel he did not name and an application with the U.S Patent and Trademark office for his report dated July 8.

Apple filed a patent application document dated July 5 that refers to a multifunctional handheld device with a circular touch pad control, similar to the Nano's scroll wheel.

Apple spokeswoman Natalie Kerris declined comment.

Long lines of people turned out on June 29 when U.S. sales began for the iPhone, a mobile phone with a music player and Web browser. Analysts have estimated that sales in the first weekend were as high as 700,000 units.

Chang said a way to follow up the iPhone with a cheaper version would be to convert the Nano into a phone and price it at $300 or lower. The iPhone sells for $500 and $600, depending on storage space.

"We believe that iPod Nano will be converted into a phone because it's probably the only way for Apple to launch a lower end phone without severely cannibalizing iPod Nano," he said noting that the new phone could have "rather limited functionality."

Another analyst Gene Munster of Piper Jaffray said he expects Apple to bring out iPods that resemble iPhone, which features such as a touch-sensitive screen, later this year. Such products would help stop iPhone eating into iPod sales.

"We believe the iPhone reveals much of what the iPod will soon be," Munster said in a note to clients, "iPods with some of the touchscreen features of the iPhone should lessen the impact of cannibalization."

Kerris also declined comment on Munster's note.

Because of the anticipated lower price for the Nano-based phone, 2008 sales of 30 million to 40 million units "is achievable," according to JP Morgan's Chang.

This would be a much larger volume than is expected of the first iPhone, Apple has targeted sales of 10 million units in 2008, which would give it a 1 percent share of the global market.

Sales of the iPhone are expected to be limited to a small percentage of the market due to its high price tag, particularly in the United States where 85 percent of consumers tend to spend $100 or less on cell phones.

But analysts forecast that a cheaper phone from Apple, which leads the digital music player market, could pose a much bigger threat to long-established phone makers such as Nokia, Motorola Inc, Samsung Electronics Co Ltd and Sony Ericsson, owned by Sony Corp and Ericsson.

Taiwan's Catcher Technology will be the "major source of metal casing" for the new phone, according to Chang, who cited an unidentified channel source.

Revenue from Apple could represent T$6 billion ($183 million) to T$8 billion ($244 million) revenue for Catcher in 2008, Chang estimated.

Printing API of Java 2D

Printing is an area where Java has changed a lot since its first version. First printing resources arose in JDK 1.1, with AWT Printing API. When JDK 1.2 has arrived, Java Printing API came along, giving support to graphic bidimensional printing (texts, images, etc). More recently, Java Print Service (JPS) was introduced. It offers a set of new features, such as dynamic knowledge of available printers. But this article will focus on Printing API of Java 2D.



Printing system of Printing API is very similar to that used to render Java 2D graphics on monitor. We must provide a paint( ) method with rendering code in order to render the screen. But in order to use printing features, we must implement a paint( ) method.



The application only needs to provide the document content to be printed and let printing system to determine when each page must be generated. This system makes possible for JVM to implement the necessary optimizations to printing process.



You need to accomplish two tasks in order to accomplish printing with Java 2D: to render pages and to manage the printing job.

Java RMI

RMI (Remote Method Invocation) is one of Java technology approaches to provide functionalities of a distributed objects platform. This distributed objects system is part of Java basic core since JGK 1.1.

Using RMI architecture, it is possible for an active object in a Java virtual machine to interact with objects in others Java virtual machines, no matter where these machines are located.
When developing a client-server application using Java RMI, it is essential defining the interface of services that are going to be offered by server object.
Services specified by RMI interface must be implemented using a Java class. In this implementation, you must indicate that this class objects can be accessed remotely.

Since you have implemented interface and service, it is now possible to create RMI client-server applications.

Execution of RMI client-server applications requires:


  • Execution of client application and of server application.

  • Execution of RMI registry service.

RMI also offers facilities to operate with available code in distributed pattern, dynamic activation and others distributed services.
