Wondering what is the differences among the digital image formats? Some of the more common ones are GIF (CompuServe Graphics Interchange Format) and JPEG (Joint Photographic Experts Group JFIF Format) .Wherever available choose the “RAW” option when taking photographs with a digital camera because RAW is a virtually lossless, unprocessed capture of data from the camera’s sensor.Saving in minimally compressed RAW means that you will always be able to come back to the data file and manipulate it however you want. By saving in the commonly seen alternative JPEG camera format, you are introducing unremovable, hard-baked processing like white balance and contrast into the image. Saving in RAW is a bit like saving a negative.The advantage of RAW is also its disadvantage in that you do have to post-process it with software like Adobe Photoshop or Adobe Lightroom post shot. Another disadvantage is its large file size. There are considerations in this medium that are different from those for print.
The No. 1 issue when dealing with online images is quality versus file size – a larger image file size usually produces a good quality image, but it slows download and consequently degrades user experience.From a monetizing sense, slow downloads mean users are more likely to get distracted and leave a Web page prematurely. Less important for smaller-site purposes, although still an issue, is that the larger the file size the more storage and bandwidth you need.What’s desired is high quality in a small file size.The more pixels or other data, and the more color in an image, the bigger the file. However, the files size can be reduced through compression. The Web browser on a computer screen lends itself to compression that would be unacceptable in large print like a billboard — garbage called “artifacts” and other degradation appear.Browsers also have limitations that restrict the types of files they can show, which eliminates most of the 70 or so commonly available file types.
Once you’ve captured your RAW image, or acquired through other means other formatted images, like printing industry-standard TIFF from a stock agency, you can concentrate on converting it to the three image file types seen natively in a browser that is without plugins like Flash.The native image file types are JPG (also known as “JPEG”), GIF and PNG. JPEG compression is “lossy,” which means the compression algorithm dumps file data that’s not necessary for a computer screen browser. Thus, getting rid of redundancy, JPEG provides for small file sizes. However, JPEG allows for 8 bits per color which is good.Drawbacks are few. The principal one is that you can’t keep editing and saving JPEGs because quality degrades.Choose GIF for Graphics as this format provides a size-beneficial “lossy” compression, but with less color support.GIF is limited to 256 colors. GIF works well when significant parts of the image have one color. GIF is poor at handling details.
Choose PNG for screen shots as PNG is the open source successor to Compuserve’s GIF, but unlike GIF, it supports 16-million colors, called “True Color”.Like GIF, it’s good for expansive areas of the same color. It’s commonly used for screen shots when displaying them within a browser environment.

You might think app design is the same, whether the software is being developed for iOS or Android. But creating highly polished, elegant-looking apps is simply easier to do when developing for iOS. That’s the prevailing conventional wisdom among developers who code for both platforms.Design is built into Apple’s DNA. Google’s legacy, on the other hand, is search. So it’s not too difficult to guess which platform places a higher premium on app U.I. and aesthetics — and which platform makes it easier to create beautiful software.
The very nature of mobile-sharing apps has changed the types of imagery that people upload. There is also an added on-the-move life-streaming nature to the whole thing. Photos found on the flowing Instagram news feed don’t look like the ones on Flickr.Instagram is a community conducive to likes and comments, whereas Flickr focuses more on displaying collections of photographs in photostreams, sets and galleries, organized by tags and maps. Yet interestingly, the most-used camera on Flickr is the iPhone4.Flickr operates more as a storage space and ongoing project.
A hacker with the handle “Hardcore Charlie” has stolen source code for VMware’s ESX hypervisor and posted it on the Internet.A hypervisor provides a virtualization layer between operating systems and the underlying hardware, creating a virtual machine. This lets users run multiple virtual machines on one processor. Hypervisors are key to virtualization and cloud computing.Hardcore Charlie claims he obtained the code for the VMware Kernel and the TraceViz GUI. He’s promised to post more VMware source code on the Interne.VMware stated that a single file from the ESX source code had been posted and that it dates back to about 2003 to 2004. It said customers may not face an increased security threat. The company is investigating the theft. The VMware documents appear to have been obtained by Hardcore Charlie during an attack on Beijing-based China National Electronics Import-Export last month.About 1 terabyte of data was pilfered in that raid, Hardcore Charlie told Kaspersky Labs. He apparently has about 300 MB of VMWare source code.CEIEC has denied that it had been hacked by Hardcore Charlie. This led the hacktivist to release more documents, including U.S. military data.
One of the worst-kept secrets in the technology space- Google Drive, is finally here — live and yours to explore.But if you’re already using a cloud service, or maybe even a couple of services the question undoubtedly arises, Do you really need another cloud platform? This question gets more complicated when you consider that Google already has a number of cloud services such as Play for music storage, Picasa for photos, YouTube for videos and even Gmail as well. Google Drive doesn’t seek to replace any of these existing Google services — though it does replace one cloud service. Instead, Google Drive seeks to replace the USB thumb drive stuffed into your backpack or purse. And, if you pay up for extra storage, maybe even the portable disk drive too. You can store all manner of file formats, and Drive gives you the option to convert files into Google-friendly formats as well.
Aficionados of the long-running sitcom Scrubs will know this one essential fact: Everything comes down to poo. Really. Tracking your bowel movements is apparently a great way to monitor your health on a day-to-day basis. This app will help you track what you ate and how it turned into a bowel movement, with your stress level and the amount of fiber, and water, in your diet – really, every ingredient that makes for poo. Email your charts to your doctor or… yeah, let’s just keep it with your doctor. Bonus feature: Tweet your poo to your friends.
This falls into the “you’ve got to be kidding me” realm. This app has the ability to get your phone to fornicate with another NFC-enabled Android device running Gingerbread or Ice Cream Sandwich. There is really not much we can do to explain that, so watch the publisher’s slightly NSFW video below. Thanks to Twitter follower Michael Nicholas for sending this one in.
As the Google Play description so helpfully points out, this is a shooting game. But it is not your normal Doom-style first-person shooter. This is more like a bad 1990s quarter-arcade shooter. You are President George H. W. Bush and the White House has been infiltrated by bad guys. An assault rifle pops out of the desk in the Oval Office and you start shooting down bad guys like you were a Duck Hunt pro. It is hard to tell if this game is mocking Bush or turning him into a hero. Either way, for a shooting game, it is not that bad.
Also apparently known as the Charlie Sheen App. There are certain things that fly on Android that Apple and its App Store guidelines would never, ever approve. This would probably be Example A. The concept is simple. Cut up a bunch of fake cocaine and pretend to sniff it. There are five levels of difficulty and the phone vibrates when you reach the appropriate level of intoxication.
No list of weird things would be complete without an entry from Geico. The App Store description says, “Just like the GEICO commercial, now you too can do dumb things with your smartphone!” Boy, can you ever. There are seven BroStaches to choose from. Put the smartphone to your lips and it will follow your words along with your ridiculous BroStache.
This app proudly proclaims itself to be, “the first interspecies game on the App Store.” Sure, we can get behind that. The game starts with two levels: a laser pointer that your cat can chase around the screen, and a mouse. You will need to pay $1.99 to fully unlock the mouse level (the upgrade comes with a free butterfly level.) You can also purchase and upgrade to move the laser pointer on the iPad with your iPhone (otherwise it moves automatically). Once your cat catches the laser pointer dot, mouse or butterfly, it accumulates points which you can share with a leader board or on Facebook and Twitter. Brilliant.
We’re all familiar with Apple’s love affair for thin devices. Although the third-generation iPad surprised many by gaining about half a millimeter of thickness, it looks like Apple could be back to trimming product dimensions by using a new kind of display technology in the next iPhone.Instead of using a display comprising a number of separate layers, Apple could use in-cell touch display technology. The report says Apple would be sourcing its in-cell displays from Toshiba and Sharp.

According to Korea IT News Apple will use Liquidmetal for the casing of the iPhone 5, which will be launched in June.Liquidmetal is the commercial name of an amorphous metal alloy developed by researchers at the California Institute of Technology and marketed by a company they set up called Liquidmetal Technologies.The alloy’s been used in more than 10 million hinges for mobile phones and smartphones, more than 2 million antennae, over 2 million cases and more than 1 million pounds of coatings materials. Apple purchased a worldwide exclusive license to commercialize Liquidmetal Technologies’ in the field of consumer electronics, according to the latter’s 10-K report filed with the Securities and Exchange Commission.With the license, Apple is likely to use the technology in future mobile devices, including the iPhone, iPad or even the MacBook Air. Liquidmetal offers a lightweight solution that has all the characteristics of metal and can be an attractive alternative to plastics.
Apple posted a job listing for a “Computer Vision specialist,” the tech-obsessed chamber began speculating which Apple product line would be employing this person’s expertise also the job posting made frequent reference to 3-D: “3-D geometry,” “3-D reconstruction” and “cameras and surfaces in a 3-D environment.” Apple could be delving into applications as familiar as simple 3-D video capture, to as arcane as real-time environment capture for an augmented-reality system.Computer vision is about enabling the computer or mobile device to make sense of a 3-D image the way humans do. “For this job application, Apple appears to be looking for someone who could help them think about how stereo cameras could look at a scene, and figure out how to do something useful for its owner.
