Important expectations of teachers from students!

No comments
Teachers always want and expect some things out of their students while the students feel all stuck. Twenty19 brings you a list some of the most common expectations of teachers from every student. If you want to be your teacher’s pet, start doing all the things listed below! ;)

“Be in discipline!”

zeph__s_discipline_wallpaper_by_fallenangelii-d5d8xdh
Every teacher wants the class to be under her control. Obedience is the key to be disciplined enough. The teacher wants all their students to have a controlled and systematic behavior.

“I want pin-drop silence in the class!”

students-in-classroom
We are sure you’ve heard this statement a lot. If you haven’t then probably you are the same person trying not to maintain the silence. Good luck with that though. ;)

“I want all my students to come first!”

IIT-JEE-exams-coming-soon
This statement is used by the teacher who actually puts the efforts to bring you to a level where you score the highest. She is the same person who has been boosting you before the exam and the same person who you will find boasting about you after you score well in your exam. :)

“Study 2 hours daily! No excuses!”

23_little
One of the most common phrase you would ever hear from a teacher.
Apart from school, every teacher expects that the students will at least spend two hours of their remaining day studying. She not only wants you to sit with your book but also believes in reading and gain the knowledge from it. Although, that rarely happens. :D

“Your attendance must be always full!”

Untitled
This teacher totally believes and expects the students also to believe that attendance is the foremost thing that helps one score the highest and be the brightest. This teacher only allows serious sick leaves and doesn’t tolerate any other excuse! Beware, she might not even allow you a sick leave. :P

The Top 5 skills you need for your dream job!

No comments
      In a world of competition, to survive and succeed, you need skills. Some of these skills are inborn while others must be nurtured. While different jobs require different skill sets, there are some skills which top the chart and apply to all.

#1 Leadership

leadership - twenty19
This may sound like some skill you need for a managerial position but companies now-a-days are looking for youngsters with leaderships traits and the ability to lead. They are looking for a talent pool that is never shy to put its hand up and take the first step forward. This is a trait which is inborn and can, with some hard work, be acquired.

#2 Team Player

Companies and hiring managers look for people who can get along well with others. They know that being a team player is an invaluable asset anyone can possess. Companies cannot afford to have talent without co-ordination or co-operation. Being someone who can put aside differences and get along well with people, can hugely boost your chances of sealing that dream job.

#3 Critical Thinking

At a time when people make decisions based more on emotion than logic, it is highly appreciable if can think before you act. Critical thinking is an attribute that defines you and shows you distinct and different in a crowd. Companies look for people who can think deep and act after having analyzed all the permutations and combinations in a problem. They look for someone who can take one shot at a problem and solve it forever.

#4 Communication

This will forever be one skill, that everyone needs to possess, to achieve success.Communication is the art of effectively conveying your thoughts so that they become seeds for an action. Hiring managers look for people who can take a thought and turn it into reality. They look for someone who can make even the most complex of topics, easy and understandable, for the simplest of minds. It is an art which one needs and one which guarantees success.

#5 Motivation

Motivation is as equally important as all the above, previously mentioned skills. Companies have started to realize that individuals who are truly motivated and enthused, drive them forward. They do not approve of someone who lacks interest and is not motivated to do his work.  Find the job which motivates you and which keeps the fire in your belly burning. That is your ticket to success.

“If today were the last day of your life, would you want to do what you are about to do today?” – Steve Jobs.

Facebook’s Messenger Platform Preserves WhatsApp’s Clarity Of Purpose

No comments

We demystified it last month, but Facebook’s $18 billion acquisition of WhatsApp should begin to make more sense to people today after the company announced that its Messenger service will become a platform for third parties — as TechCrunch first reported last week.
The Messenger Platform will allow developers to deeplink their apps into Messenger, and it will also become a communications channel for businesses and customers. These moves aren’t a huge surprise — they’ve been pioneered by Line and WeChat in Asia for years, and Facebook’s head of Messenger, David Marcus, gave plenty of hints in an interview with Wired last year. But, while the tech industry chews on the immediate implications, the path for WhatsApp is clearer than ever.
If Facebook is a platform (which it now is), then WhatsApp will continue to be a communications utility. WhatsApp’s simplicity is the yin to the yang of Messenger’s busy platform.
“No ads, no games, and no gimmicks” has long been the ethos for WhatsApp’s founders, who instead stick to the business of connecting people. Initially that was via free messages — WhatsApp has eclipsed SMS in volume — and now it includes voice calls,which are slowly rolling out on Android devices first.
tumblr_inline_n19kcby0jA1qzzumw
A note from WhatsApp co-founder Brian Acton, via Sequoia Capital
If Facebook didn’t have Messenger — or WhatsApp had remained independent — there would be pressure to introduce games, business-consumer messaging or other features that are money spinners in Asia and way more lucrative than WhatsApp’s $1 per year subscription. (Though, for what it’s worth, I’ve not paid a cent for my three years using it.)
However, with Messenger adopting the platform approach and offering a more interactive experience, WhatsApp can be its antithesis and focus on basic communication.
There’s an argument that Facebook will bring WhatsApp under the Messenger Platform umbrella over time, which is easy to say when you consider that the service has 700 million monthly active users. But there’s likely a vast overlap between that user base and the 600 million that Facebook says use Messenger; duplicating features across the two would make no sense.
There’s also a strong case to offer a simplified chat app option. WhatsApp’s core strength is its ease of use. There needs to be a channel for users like my mum who don’t want bells and whistles, or those using low-end devices or spotty mobile internet connections.
Yes, WhatsApp may not make the kind of revenue per user as Messenger if it stays simple, but I’m willing to bet that Facebook is happier to have it as a differentiated experience that keeps non-Messenger users inside the Facebook ecosystem in some form. That’s better than losing them to a rival service. Besides, more subtle monetization options may be forthcoming for WhatsApp in the future.
Update: WhatsApp co-founder Brian Acton told a panel at Facebook’s F8 group that “[Messenger] Platform is not top-of-mind for us.” WhatsApp is focused on product development, he added.

Facebook Finds Strength As A Family, Not An App

No comments

F8 started with a family photo. But not of the Zuckerbergs. Of Facebook’s products. “Facebook used to be this one blue app on your phone, and now Facebook is a family of apps” said its CEO as he showed off the user counts of the different family members. Facebook Groups with 700 million. WhatsApp with 700 million. Messenger with 600 million. Instagram with 300 million. And the patriarch, Facebook, with 1.4 billion.
Rather than just being a social network, Facebook sees strength as an interconnected clan of experiences — developed in-house, acquired, and tapped in from outside.
Mark Zuckerberg F8 2015
The subtext of Zuck’s “family” quote is that one app can’t do everything. On mobile, people want lean, purpose-driven experiences. Cramming everything into a one-size-fits-all can make it slow and bloated.
But when you’re talking about trying to connect every human on earth, a singularly focused app alone can’t possibly meet the diverse needs of a diverse population. Zuckerberg explained “We’re building this family so we can offer unique, world-class experiences for every way that people want to share.”
There’s safety in numbers.

Post-Facebook

An early Facebook For iOS App
An early Facebook For iOS app
Facebook was built as a website, not an app. At 11 years old, it’s downright ancient by social standards, and its age is starting to show. The popular belief is that teens are over Facebook, or at least what it used to be. Luckily, Facebook saw this coming.
The Facebook family started when it acquired Instagram, the new darling amongst youngsters alongside Snapchat. Instead of rolling it into Facebook or rebranding it as Facebook Camera, it let Instagram be Instagram. If people didn’t want to read links or deal with the personal drama of status updates on Facebook, they could just let the pretty pictures flow over their eyes.
As mobile became the dominant way people connected, Facebook saw that its messaging system’s growth was hampered by keeping it buried inside the main app.
When people are on the go, they usually need to communicate. On desktop, messaging was a feature. On mobile, Facebook realized it’s a whole app — one people might use more than the News Feed. So it spun out Messenger to great success. And it acquired WhatsApp for what seemed like a crazy $19 billion…until it became obvious that messaging was the center of the smartphone.
Zuckerberg said this morning that five years ago, most content on Facebook was text. Now it’s photos, soon it will be video, and eventually it will be immersive content like virtual reality and augmented reality. If the content sharing of the future requires a headset, Facebook needed one, so it acquired Oculus.
Facebook Family Of Products
By starting a family, Facebook has insulated itself from disruption, now and in the future. If competitors controlled the top photo sharing or messaging app, they could use those as a wedge to pry themselves into Facebook’s core social networking ad business. But surrounded by its family, Facebook has largely managed to repel those threats.
Mark Zuckerberg declared “There are so many ways that people want to share that this family will keep growing.”

An Extended Family

Still, Facebook can’t buy or build everything. Snapchat, for example, turned down what’s reported to be at least a $3 billion acquisition offer. And when Facebook tried to clone Snapchat with Poke and then Slingshot, it failed miserably both times.
But there’s a third option beyond buy or build: partner. This was the strategy Facebook revealed today.
David Marcus F8

Years ago, it came to the same conclusion on the web. It knew people wanted a wider variety of things to do on Facebook, from using utilities to playing games, but it didn’t have the time, resources, or know how to create them all in-house. That led to Facebook’s first platform. Developers got a built-in userbase, virality, and ways to make money, and Facebook soaked up all the engagement driven by the platform apps.
Now Facebook is doing the same on mobile with the Messenger platform. It’s extending what counts as family by inviting over 40 developers to build companion apps for creating and discovering content to be shared through Messenger. This time around, developers get help with discovery and virality, and again, Facebook gets to soak up all the engagement they lure in. Messenger usage translates to platform lock-in, driving views of Facebook’s News Feed where it shows ads.

Using Facebook Messenger platform content apps

Having played with a few of the Messenger content apps, they’re definitively not things Facebook would build. There are slews of goofy GIF makers, ways to layer cartoony animations or special effects over you photos, or record lip-sync videos.
That’s the whole idea, though. To each their own Messenger app.
More serious adults might like sharing ESPN clips, while kids will prefer creating custom emoji. As Zuckerberg noted “People need to be able to share what matters to them with all the different groups of people they care about this is how we give people the power to make the world more open and connected.”
It’s an approach similar to the monolithic chat apps of Asia, like WeChat and Line. By letting other apps build companion experiences, they strengthen the community around their core apps.
F8 also unveiled more ways to join the family. Websites can now integrate a revampedreal-time Facebook comment widget that entrenches the company’s identity system. They can syndicate Facebook videos with a new embedded video player, using extra views to lure publishers into posting their content on Facebook. And businesses can start communicating with customers via Messenger.

Keeping The Family Together

While the Messenger platform made big waves today, it didn’t exactly have the most prestigious launch partners. Only a few of the developers that built Messenger apps, like Giphy, Imgur, and JibJab, already had a healthy following. The question will be whether brand-name companies will want to build a dedicated Messenger companion app to be adopted by Facebook.
As Andreessen Horowitz partner and mobile expert Benedict Evans wisely noted:
When more apps get built for Messenger, the discovery benefit of the curated platform will diminish. And if these apps don’t see business advantages from being a Messenger companion, like getting downloads of their main apps, they might not bother to build or maintain another set of code.
Keeping partners loyal and feeling valued has been sore spot for Facebook in the past.
851557_383156055132709_1792461819_n-1It cratered game companies like Zynga when it reduced virality on its web platform. News reader apps from The Guardian and Wall Street Journal got burned when the News Feed stopped promoting them. Facebook has copied features of apps built atop it. Platform whiplash rocked developers as Facebook rapidly changed its APIs around 2009. Facebook’s little-known HTML5 app platform was abandoned soon after birth. Now, Page admins are up in arms as their News Feed reach decreases.
In an attempt to repent, started “Operation Developer Love”.  Last year’s F8 motto was “Move Fast With Stable Infra”, an update to its less mature slogan “Move Fast And Break Things”. It instituted a one-year API stability guarantee, and has since stressed transparency around News Feed changes.
When I asked how Messenger will make developers feel valued during Messenger head David Marcus’ F8 panel Q&A, he insisted “The beauty of the platform is that developers get attribution. If your friends are using apps and sharing content with you, you’re able to download the app and share with more friends.”

But the sour taste of unreliability is hard to wash out of developers’ mouths, and some virality now might not be enough. Zuckerberg concluded that “Moving from a single service to a family of world-class apps is the biggest change we’ve made in years.”
If Facebook wants to keep the family together, it will have to prove its commitment to partners. The company has consistently countered developer and marketer complaints by saying it prioritizes what’s best for its end users. If the audience gets burned by spam, outdated functionality, or annoying marketing posts, there won’t be anyone left to use Facebook’s partner apps in the future.
But just like a real family, even if you do have favorites, you can’t say that aloud.

When Facebook was just a young bachelor, cavorting around colleges, it didn’t have to worry about anyone but itself. But it’s entering a new life phase with new responsibilities, and it will have to balance its affection for users, advertisers, developers, and its own bottom line. Family isn’t always easy, but its the only way Facebook’s legacy will live on.

Do-it-yourself healthcare is closer than you think

AUSTIN–Healthcare-related innovation was everywhere at South by Southwest Interactive this year. There were sessions on healthcare IT, big data, wearables, and innovative startups that are using technology to upend the status quo. For example, Tim O’Reilly gave a talk about adapting the same experience-focused approach used by companies such as Apple, Google, and Uber to reimagine health care delivery.
And if there is any industry ripe for disruption, it is healthcare. According to federal government statistics, healthcare expenditures in the U.S now exceed $3 trillion and represent 17% of the nation’s GDP. Yet despite consisting of such a huge slice of the economy, and incorporating large amounts of new technology for diagnosis and treatment of diseases in the past 30 years, the industry has failed at delivering cost-effective care. Compare that with the computing industry, where the million-dollar supercomputer of 20 years ago now fits in your pocket and costs $600 unsubsidized. Thanks to smartphones, cloud computing, sensors, and other technology, today’s health tech entrepreneurs see plenty of opportunities.
One such startup is Audicus. Audicus is aiming to upend the current model and cost structure for obtaining hearing aids. If you’re old enough to think you need a hearing aid, the drill is something like this: Your doctor refers you to an audiologist’s office. The audiologists give you some tests with specialized equipment. They get some detailed data on your hearing loss, and recommend whether you need a hearing aid (or two) and what the options are and their costs. Typically, hearing aids run $2,000 to $3,000 per ear for good-quality smaller ones. Also, most insurance plans don’t cover them, so this is an out-of-pocket expenditure for most patients.
Instead, Audicus is using the Internet to enable a simpler process, with better price transparency, to hearing aid patients. While not eliminating a professional audiologist test, it is using the Internet at what it does best – use technology to present information about a product, enable transparency by clearly spelling out costs, and providing easily accessible post-sale support.
This is not a futuristic technology solution per se, but it does provide an avenue for more innovation. Given the right set of headphones, software, and smartphone based application, why can’t that audio test be administered over the Internet by an audiologist at much lower cost? With new Bluetooth-enabled hearing aids already available, why couldn’t the adjusting and tweaking of the hearing aid be done over the Internet as well? We likely have all the base technology to do this in today’s platforms. What’s required is a rethinking of the model to effectively use it. Audicus looks to be able to do these types of innovations in the future.
Tinnitracks
Along the lines of hearing, Tinnitracks is using music therapy to treat chronic Tinnitus, or ringing in the ears. According to recent neuroscientific findings, Tinnitus can be mitigated by “tuning” your hearing with filtered music. Tinnitracks is a Web application that analyzes your own music that you listen to. It then analyzes it for your tinnitus frequency (which an audiologist or ENT specialist can determine) and filters the music that will help tune your ears so as not to trigger the ringing (pictured, right). As Tinnitus is not an easily treatable problem, if this really brings relief to sufferers, it will be a great use of technology for do-it-yourself therapy.
Another interesting company launching soon is Opternative. It is gearing up deliver $30 refractive eye exams over the Internet, using your computer and a Web-enabled phone. Using the same principles as an in an office exam, it will deliver a legal prescription signed by an optometrist that reviews the results of the test. And you can’t even cheat by memorizing the eye chart, as they randomize it.
First Derm is an interesting telemedicine application. Using an IOS or Android app, a user can take a picture of a skin condition or other issue you might otherwise need to book an appointment with a dermatologist for. You take two pictures of the affected area, and provide some basic information, but the initial case request is anonymous. For a $40 fee, a licensed dermatologist reviews the case and responds to you in 24 hours. First Derm says that in 70% of cases, the issue can be treated with an over-the-counter medication. Currently they are limited in that they cannot write prescriptions. In those cases, they will refer you to a local dermatologist. Given the high cost of seeing a specialist, and that specialist co-pay amounts for many insurance plans are now $50 or even more, this is a good use of technology for convenient treatment of non-serious dermatology issues.
So many other startups and more established companies are taking disruptive approaches to solving problems in health care. In many of these cases, the technology platforms we need to build better solutions to health issues are already here. What we need is deep thinking about what really needs to be accomplished, a customer-centric approach (not doctor- or institution-centric), and clever use of technology to change the current models and inefficient cost structures of health service delivery.

Google discovers new security holes in SSL — is the entire system fundamentally flawed?

No comments
Data security

Share This Article

Google has discovered that an intermediate certificate authority had issued unauthorized certificates for multiple Google domains. The problem arose because the intermediate authority, MCS Holdings, had issued certificates for the Google domains, despite not holding those domains itself.
The reason it’s critical that companies not mint certificates for websites they don’t operate themselves is because doing so breaks the function of SSL itself. Here’s how the system is supposed to operate:
How SSL works
Your PC contacts a Google server, which returns a certificate. Your computer uses that certificate to encrypt a data session. The server confirms that the key is good and establishes the secure session with your PC. When certificates are signed by third parties, it allows the false server to execute a classic man-in-the-middle attack.
Main_the_middle
In a man-in-the-middle attack, an intervening certificate authority can pretend to be the genuine issuing authority, particularly if the intermediate certificate company is given the full authority of an issuing CA, which is what happened here. That’s not supposed to happen, as Google points out — the original Certificate Authority, CNNIC (the Chinese Internet Network Information Center) should never have given such authority to MCS Holding in the first place.

Fixing the TLS/SSL system

The problem with the SSL system — in addition to all the bugs, at least — is that it relies on the idea that Certificate Authorities will always issue good certificates. History has proven this simply isn’t true — multiple Certificate Authorities have been hacked, including companies like VeriSign and the now-defunct DigiNotar. Google wants to revamp the process of issuing certificates with its Certificate Transparency initiative. This project would:
  • Make it impossible (or at least very difficult) for a CA to issue a SSL certificate for a domain without the certificate being visible to the owner of that domain.
  • Provide an open auditing and monitoring system that lets any domain owner or CA determine whether certificates have been mistakenly or maliciously issued.
  • Protect users (as much as possible) from being duped by certificates that were mistakenly or maliciously issued.
Certificates would be logged, and the logs would be monitored by public servers that would periodically check to see if malicious or unauthorized certificates were being used across the net. For example, if Certificate Authority XYZ issued an unauthorized certificate for Gmail, a Certificate Transparency Monitor would detect the problem and alert Google itself. Finally, the logs and monitors would themselves be guarded by a cryptographic watchdog program, which would check to ensure that SSL certificates were properly logged and that the logs weren’t tampered with.
The other problem with the TLS/SSL system, beyond the fact that it relies on intrinsic trust, is that the system can be easily subverted. Unless certificates issued by a particular authority are revoked, those certificates can continue to be used to wreak havoc. This is why the recent Lenovo-Superfish debacle was so dangerous. Until Google, Microsoft, and Firefox updated their own software to reject the Komodo certificate, it remained available and functional — effectively end-running around any security that a website might try to provide.

Google's latest object recognition tech can spot everything in your living room

Google object recognition spots items in a living room
Automatic object recognition in images is currently tricky. Even if a computer has the help of smart algorithms and human assistants, it may not catch everything in a given scene. Google might change that soon, though; it just detailed a new detection systemthat can easily spot lots of objects in a scene, even if they're partly obscured. The key is aneural network that can rapidly refine the criteria it's looking for without requiring a lot of extra computing power. The result is a far deeper scanning system that can both identify more objects and make better guesses -- it can spot tons of items in a living room, including (according to Google's odd example) a flying cat. The technology is still young, but the internet giant sees its recognition breakthrough helping everything fromimage searches through to self-driving cars. Don't be surprised if it gets much easier to look for things online using only vaguest of terms.

How to Choose BitLocker Drive Encryption Method and Cipher Strength in Windows 10?

No comments
BitLocker is an encryption method that enables users to lock the different drives in Windows. The drives which are protected by BitLocker are accessed by passwords. Windows has provided opportunity for users to choose and configure the cipher strength and algorithm used by BitLocker Drive Encryption. This can be achieved via the Local Group Policy editor. The Local Policy Editor will let you configure and select the cipher method for BitLocker encryption. By default it is not configured but you can choose your choiceable encryption method by enabling the Policy Setting. If the drive is already encrypted or if encryption is in progress, the encyption method will have no effect. If you leave the policy unconfigured, then BitLocker will use the default encryption method of AES 128-bit with Diffuser or the encryption method specified by the setup script.

Steps to Choose BitLocker Drive Encryption Method and Cipher Strength in Windows 10

1. Press Windows_R to open Run Window. Type gpedit.msc to open Local Group Policy Editor.
gpedit
2. Now navigate to the following location Computer Configuration-> Administrative Templates->Windows Components-> BitLocker Drive Encryption.

The 2 in 1 pictured here is a 12.5" screen that is just 7.2 mm thick with keyboard detached and weighs 670 grams. The Surface Pro 3 – for comparison – is 9.1 mm thick and weighs 800 grams. It includes a media dock that provides additional cooling for a burst of performance. The next-generation chip is purpose-built for 2 in 1s and will hit the market later in 2014. Called the Intel Core M, it will be the most energy-efficient Intel Core processor in the company's history with power usage cut by up to 45 percent, resulting in 60 percent less heat. The majority of designs based on this new chip are expected to be fanless, with up to 32 hours of battery life, offering both a lightning-fast tablet and razor-thin laptop.
Intel is also delivering innovation and performance for the most demanding PC users. During the conference, the company introduced its 4th generation Core i7 and i5 processor "K" SKU – the first from Intel to deliver four cores at up to 4 GHz base frequency. This desktop processor, built for enthusiasts, enables new levels of overclocking capability. Production shipments begin this month.
Intel also outlined progress towards a vision to deliver 3-D camera and voice recognition technologies to advance more natural, intuitive interaction with computing devices. The latest RealSense software development kit will be made available in the third quarter of 2014, providing opportunity for developers of all skill levels to create user interfaces.
Computer processors continue to get smaller, faster and cheaper thanks to Moore's Law – expanding the scale and potential for technology in everything from cloud computing and the Internet of Things, to mobile phones and wearable technology.
"The lines between technology categories are blurring as the era of integrated computing takes hold where form factor matters less than the experience delivered when all devices are connected to each other and to the cloud," said Renée James, Intel Corporation President. "Whether it's a smartphone, smart shirt, ultra-thin 2-in-1, or a new cloud service delivered to smart buildings outfitted with connected systems, together Intel and the Taiwan ecosystem have the opportunity to accelerate and deliver the value of a smart, seamlessly connected and integrated world of computing."
