When you submit your e-mail thorough a web form, let say:
If you use client-side validation (Javascript) – the browser (Firefox, IE, Chrome…) will validate the e-mail without having to send it to the server.
Which means, no Internet connection needed, it’s fast since you don’t have to wait for the page to be refreshed to see the validiation..With Server side validation, everything is the opposite. I would say client side validation is safer.
But, if someone has disabled javascript in their browser then that would mean, their web browser is unable to validiate the form so i guess like the above person indicated.. server side validation would be safer, because they can not turn off server validation in their browser.

Facebook may change privacy policy again
Facebook has proposed “updates” to its privacy policies that explain how the social networking giant would use personal data of about 1.2 billion users to deliver advertising and other personalised services.
The social network is proposing these updates as part of a settlement in a US court case relating to advertising, it said in a statement.
The website has revised its two key documents — Data Use Policy and Statement of Rights and Responsibilities — to explain how a user’s name, profile picture and content may be used in connection with ads or commercial content.
The proposed updates say: “You give us permission to use your name, profile picture, content, and information in connection with commercial, sponsored, or related content (such as a brand you like) served or enhanced served or enhanced by us.”
The earlier policy line, “you can use your privacy settings to limit how your name and profile picture may be associated with commercial..”, has been removed.
On the proposed updates, Facebook Chief Privacy Officer, (Policy) Erin Egan said: “We revised our explanation of how things like your name, profile picture and content may be used in connection with ads or commercial content to make it clear that you are granting Facebook permission for this use when you use our services.”
Facebook also said that it may use profile photos of users to help their friends tag them in photos.
The proposed Data Use Policy says that choosing to make information public would allow anyone, including people off Facebook, to be be able to see it.
Also, the website would also have information about the computer, mobile phone, or other devices that are used to install Facebook applications. Other information like IP address, mobile phone number, browser and location of the user would also be accessible to the website.
“We may get your GPS or other location information so we can tell you if any of your friends are nearby, or we could request device information to improve how our apps work on your device,” says the new policy.
Facebook said that users can review and comment on the proposed updates in the next seven days and it will “carefully consider feedback” before adopting any changes.
The proposed updates came after a US court early this week granted approval to Facebook’s $20 million settlement of a lawsuit over its ‘Sponsored Story’ advertisements.
Apple rolls out iPhone trade-in program in U.S. stores
(Reuters) – Apple Inc (AAPL.O) has launched a trade-in program in its U.S. retail stores for older models of its iPhone as it gears up for the launch of a new version of the smartphone, it said on Friday.
Apple will give customers a credit for their old phones to be used toward the purchase of a new model, an Apple spokeswoman said.
A thriving industry exists for older versions of smartphones, especially the iPhone, on websites such as eBay (EBAY.O) and Gazelle. Even broken iPhones can fetch as much as $125 from vendors, who resell them in the United States and internationally.
Gazelle Chief Executive Israel Ganot estimated the used smartphone and tablet market in the United States will reach $14 billion by 2015.
“So there’s obviously a huge opportunity here for multiple players,” he said.
Apple shares dipped nearly 1 percent to $487.46.

What is the difference between client side and server side validation?
Client side validation means the validation of a piece of data is executed on the client’s machine, while the server side validation means that the data is sent to server side first, then the validation is carried out.
This would need some examples to put the terms in context. Client side validation, for most of the software that runs on a PC without network or internet connection, if there is any validation, there is no distinguish of “client” or “server”, because they are the same (the PC).
But for internet (not limited to this, it could be network, 2 iPads) connections for example, let’s say the web page ask you to provide a password entry. The validation of the password entry may occur on both client side and server side. The client side (your internet browser on your PC) validation may use JavaScript to check the length of the password string (not the content of the string) to see if it exceeds a certain length (e.g., minimum of 6 characters). If yes, then the data is sent to server side to be validated (the entered value against the registered value). That server maybe at the other side of the globe.
Client side validation will be written using client side scripts like JavaScript or VB Script. Whereas the server side validation will be written using your server side programming language such as PHP, JSP, PERL or anything you are using. Always go with Server side validation, it will be very helpfull, if your client side script has any error or the script is disabled in client’s browser.
Samsung Opens Registration For Its Very First Developer Conference
Samsung is pretty much Apple at this point. It may use Android as the base of its products, but it builds its hardware around its own software and services. As such, the company is doing what every other platform holder does – host a developer conference.
Samsung announced today that registration is now open for the first annual Samsung Developers Conference. The conference is being held in San Francisco and will last from October 27 to the 29.
So, what can you expect from the first ever Samsung Developers Conference? The company’s wide range of Galaxy mobile devices will obviously be represented, but Samsung doesn’t just make the world’s most popular Android device. It also builds smart TVs and other software that it wants developers to create apps for.
Samsung won’t be exclusively sticking to Android devices at the event either as some of the planned events revolve around the company’s Tizen mobile operating system. Samsung may be using it to target low-end devices for emerging markets, and developers will need to know all about it if they want to cash in on the potential digital gold rush.
It should be noted that the most interesting aspect of Samsung’s Developer Conference is that it exists. Google already has the Android developer conference locked up with Google I/O. Sure, there are other conferences, but you go to Google I/O to learn straight from the people building the platform. For Samsung, its developer conference looks like another attempt to distance itself from Google, especially with the focus on Tizen.
With Samsung quickly matching Apple in terms of brand recognition, it wouldn’t be surprising to see Samsung ditch Android in the near future. It’s not like the company needs Android to be successful as long as it can provide the same user experience with its own software. This developer conference may be the first step in convincing developers
A Camera That Sees like the Human Eye
IBM’s brainlike computer architecture paves the way for a new kind of artificial vision.
The retina is an enormously powerful tool. It sorts through massive amounts of data while operating on only a fraction of the power that a conventional digital camera and computer would require to do the same task.
Now, engineers at a company called iniLabs in Switzerland are applying lessons from biology in an effort to build a more efficient digital camera inspired by the human retina.
Like the individual neurons in our eyes, the new camera—named the Dynamic Vision Sensor (DVS)—responds only to changes in a given scene. This approach eliminates large swaths of redundant data and could be useful for many fields, including surveillance, robotics, and microscopy.
“Your eye and my eye are digital cameras too. [They’re] just a different kind of digital camera,” says Tobi Delbruck, the chief scientific officer at iniLabs. “We had machine vision that was as good as possible with existing architecture and hardware. But compared to biology, machine vision is pathetically poor.”
An ordinary camera will take in everything it sees, storing the information to be processed later. This uses up a lot of power and a lot of space. Neurons in the eye, however, fire only when they sense a change—such as when a particular part of a scene gets brighter or dimmer. The DVS mimics that selectivity, transmitting information only in response to a shift in the scene. That takes less power and leaves less information to be processed.
This feature could be especially useful for recording scenes that do not change often. For example, when sleep researchers videotape their subjects, they are later forced to comb through hours of uneventful footage. With a sensor like the DVS, important, active portions of the data are automatically highlighted.
The pixels in the DVS also mimic the way an individual eye neuron will calibrate itself to a particular location: that cell and those responsible for another area will respond to incoming data in slightly different ways, so one neuron might be very sensitive to input while another takes more stimulation to fire. Similarly, each pixel of the DVS adjusts its own exposure. This allows the DVS to handle uneven lighting conditions, though it also requires enormous pixels that are 10 times the size of those in a modern cell-phone camera.
The DVS is built to work with IBM’s new TrueNorth computer architecture (see “IBM Researchers Show Blueprints for Brainlike Computing”). TrueNorth is a programming approach that mimics biology—information is stored, processed, and shared in a network of “neuromorphic” computer chips, inspired by the neural networks in the brain.
“What we’re talking about—the cameras sending information when something changes—is actually a very central theme to how the brain works, or at least how neuroscientists think it works,” says Nabil Imam, a computer scientist at Cornell University, who is part of the Cornell team that helped IBM develop its neuromorphic chips. “We’re capturing brain features at a high level.”
By combining their camera with TrueNorth architecture, Delbruck and his team believe, they will achieve a device that’s better at handling dynamic, real-time problems.
The DVS is available for purchase for about $2,700 and has been used in several research projects, including one that recorded traffic and another that involved tracking particles in a fluid. The team plans to continue improving the device. The next goals are to add color sensitivity and to enlarge the camera’s retina from its current resolution of 240×180.
Windows 8.1 release date, price and features
Microsoft has revealed full details about the comprehensive update to Windows 8, now known as Windows 8.1 and formerly known as Windows Blue. We’ve also had plenty of time with the new update, so check out our brand new Hands on: Windows 8.1 review.
The Windows 8.1 release date is October 17 – it will be available to existing Windows 8 users for free on Windows Update. It will be available to buy in retail from October 18.
Development of Windows 8.1 is complete, confirming what we knew would be a significant update to Microsoft’s operating system in time for the holidays this winter. While the “release to manufacturing” moniker does ring a bit of finality to it, this is by no means the end of the line for the OS. Development will continue until its general availability which is slated for October 17th.
Between now and then, Microsoft will issue a series of “quick fix engineering” (QFE) updates to the manufacturers while they are building their next batch of goodies.
The official confirmation from Microsoft: “Today we are excited to share that starting at 12am on October 18 in New Zealand (that’s 12:00pm in the UK and 4:00am in Redmond – October 17th). Windows 8.1 will begin rolling out worldwide as a free update for consumers on Windows 8 through the Windows Store. Windows 8.1 will also be available at retail and on new devices starting on October 18 by market.”
October will mark a year since Windows 8 was released. There’s also a Windows 8.1 RT version, too, if that floats your boat.
To whet our appetites in the meantime, Microsoft has released a preview version, called the Windows 8.1 Release Preview. It’s now available to download.
Apple patents new unibody hinge to make laptops even thinner
The size of our devices are stuck at something of a bottleneck. We can’t exactly make them smaller because they’re so reliant on large, easily visible displays. So, the industry makes do, and makes the devices thinner, which reduces overall size without compromising display size. One object standing in the way of even thinner laptops is the hinge, and Apple might have found a way to remove that from the design equation.
Yesterday, a new patent application was published that describes “flexible segments” that interlock to form a rigid material. The material used isn’t some kind of top-secret new wonder metal only found deep within Apple’s subterranean volcano lair, but rather a process that can take rigid material — such as plastic or metal — and can cut it in such a way to create the flexible segments. The flexible segmented hinge could bend at various degrees, but that depends on the segments being cut in different patterns. The patent claims that when using this method instead of a standard hinge, the overall thickness of the device can be reduced. Considering laptops like the MacBook Air are already so thin that it feels like picking it up will cause it to snap in half, making the hardware even thinner is certainly intriguing.
Even more intriguing, this cutting method could mean that laptops can become one fluid piece of metal or plastic, rather than being separate sheets of material attached through a hinge. The cut-hinge technique could also apply to other products, such as headphones or really anything else that uses a hinge, like a door.
Though MacBooks might need a drastic design refresh sometime soon — as we’ve grown accustomed to thin, silver laptops with iterative hardware upgrades — the existence of this patent doesn’t mean you’ll soon have a MacBook Air so thin that you’ll have to shut the ceiling fan off to make sure it doesn’t blow off the desk. Instead, we might see this kind of hinge first applied to cheaper products, such as the headphones that come with iPhones, or the iPad’s Smart Cover.
However, the possibilities the cut-hinge may bring could be quite impressive. Smartphones are already extremely stale in terms of design in that they’re all similarly sized flat rectangles. With the direction in which the phone industry has been moving — larger displays — phones are already getting too big for the intent of a portable device. Perhaps Apple can bake this cut-hinge into not only the casing of a device, but also the display itself. If so, we could finally have a full smartphone touchscreen that can fold on itself to become smaller in your pocket, but unfold to a regular smartphone size. At least this patent facilitates that dream.

The Latest Smartphone – HTC Sensation XE with Awe-Inspiring Features
The headphones are the Monster iBeats model, and would be rather costly if you were to buy them separately. The gadget has a built in microphone as well. When the headphones are plugged in, by evasion HTC’s music player gives you the option of having new improved and improved controls. It sounds amazing and attractive too, when you have the beats off option activated. With beats turned on, the music has depth and even with treble turned up to the max and it works fairly well with most tracks.
Hardware with Awesome Music
The original Sensation was recognized for both its looks and performance. The rebirth of the Sensation is certainly glorious. Featuring a combination of features, such as Beats Audio and the speed and style you have come to expect, you would be mistaken if you did not take a closer look at this phone when you are in the market.
The Sensation XE is great both in terms of a phone as well as a music device. The fast dual-core processor assists its speed, and battery life has a reasonable duration of 5 hours and 20 minutes, which is on average with other Android Smartphones. The screen is also amazing. Its high 540×960 (qHD) declaration makes text and images sharp, and there’s plenty of opposition. The screen is also bright and it has been found that the middle brightness setting is more than enough for general use.
Running the Ice Cream Sandwich version of the operating system, this phone is comfortable besides other high end phones. If you enjoy a phone that looks as good as it works, then the black case with red and silver detailing is certain to please. Sophistication and comfort meet with this device, offering a sturdy and comfortable feeling in the hand and pocket.
Those of you who intend to use this phone to enjoy music should be pleasantly surprised. Those of you who won’t rely on this mobile phone as a music player will also be pleased by the increased speed of this device when compared to the original. Powering the change you will find a Dual-core CPU of 1.2GHz. These features place this device in close competition with other smart phones. I wouldn’t be surprised to see this phone remain at the top of the market for quite some time to come.
Software
Increasing the performance of this phone was clearly important to HTC since they used a 1.2GHz dual core that has been recognized as a leader in the field. The RAM of this phone comes in at just under one gig. You most definitely will notice that this operating system has been optimized to give you a much more responsive interface. Throughout this powerful little device you will be pleasantly met with a smooth operating experience that improves upon the original. It is safe to say that this phone is more than capable of satisfying most users. I believe that HTC has become a serious contender with this phone.
Women in Engineering Earn 25% Less Than Men
Women who work in engineering or optics earn less than men, and the wage gap peaks mid-career, a new survey finds.
Median salaries for men in these fields were 36 percent higher overall than for women. The median salary for men was $79,755, compared with $58,431 for women. Men and women had the largest salary difference in Middle Eastern countries.
The findings were detailed in the International Society for Optics and Photonics (SPIE) 2013 global salary report.
Men earned 140 percent more than women in technical fields in the Middle East (at all income levels), 63 percent more in Asia (in higher-income jobs), 41 percent more in Europe (in higher-income jobs) and 32 percent more in North America (at all income levels), the survey found. The smallest gap was in Oceania, where men earned only 9 percent more than women in tech fields (at all income levels).
The engineering income gap between men and women was the widest during the mid-career years. After 16 to 20 years of employment, men earned 43 percent more than women, compared with 8 percent more after fewer than five years of employment, and 24 percent more after more than 30 years of work. [5 Reasons Women Trail Men in Science]
Male survey respondents also reported working longer hours than women. Between 25 and 30 percent of the men said they work 50 hours or more per week, compared with about 20 percent of women. But the number of hours worked is just one of many factors that might explain the difference in pay mid-career, the report’s authors noted.
The pay difference varied by employer type as well. Men earned more than women at companies, government laboratories, and private labs or research institutes. Men had the greatest advantage at “Other research institutes,” where they earned 79 percent more than women. In civilian government jobs, however, men actually earned 11 percent less than women.
Men made up 83 percent of the survey sample. SPIE sent survey invitations to its global customer database in April. The survey yielded a total of 6,752 valid responses.
iPhone 5S release dates, specs keep pouring in
Rendering of a champagne-colored iPhone 5S: It will be interesting to see if Apple still has some big surprises in store that analysts and the media haven’t covered yet.

We have iPhone 5S release dates, colors, and specs. Did I leave anything out?
Oh yeah, I forget to mention that they’re all just rumors. But there’s little left to the imagination these days when Apple rolls out a new product.
Apple is widely expected to hold an event unveiling the new iPhone on September 10. Japan’s Nikkei said sales of the device will begin September 20 in that country, and then Chinese newspapers chimed in with a release date there of late November (due to China’s verification process).
Here’s what we’ve heard about prominent specs:
- Camera: Probably the most important feature for the consumer is a better camera. The latest speculation on the camera claims it will get a larger f/2.0 aperture (that would match the HTC One) with dual LED flash. If accurate, that aperture would be significantly larger than the iPhone 5‘s. That means more light gets through, improving image quality and low-light performance.
- Fingerprint scanner/reader in the home button: That technology is likely coming from AuthenTec, a fingerprint sensor technology company that Apple acquired last year. The larger point is the iPhone 5S may mainstream biometric technology, improving electronic payments and making it easier to get music and sensitive data from the cloud.
- Chips: A 128GB flash storage option is the freshest speculation. That seems like overkill for most consumers but then 16GB seemed like a lot when the iPhone 3G came out. An updated A7 processor is also expected. Remember, the iPhone 4S got the new A5 processor when it was released in October 2011.
- New 3G/4G standard support: Versions of the 5S (and 5C) may support China’s 4G TDD-LTE standard. That could mean a huge boost in market penetration in China (and global market share) for Apple. (That support may also include China’s TD-SCDMA.)
It’s almost needless to mention at this point that there may be a gold iPhone 5S along with the standard black and white versions. The important point is that it most likely won’t be a garish gold but a more subtle champagne color.
I think that about covers it — for now.
