MS-DOS Source Code for First Time Ever

OPEN MS-DOS Source Code

Early tech fans might remember the good 'ol days of Microsoft MS-DOS, the company's first operating system from the 1980's. Now, with the help of the Computer History Museum, Microsoft is making the source code for DOS available to the public for the first time ever. Get excited, hackers.

The Computer History Museum, based in Mountain View, Calif., is making MS DOS 1.1, 2.0 and Word 1.1a available to help fans and technologists better understand the history of computing.

Microsoft announced the move in a blog post on its website and detailed the early beginnings of the iconic software.

In 1980, IBM approached Microsoft to work on a project code-named “Chess.” What followed was a significant milestone in the history of the personal computer. Microsoft, at the time, provided the BASIC language interpreter for IBM. However, they had other plans and asked Microsoft to create an operating system. Without their own on hand, Microsoft licensed an operating system from Seattle Computer Products which would become the foundation for PC-DOS and MS-DOS.

IBM and Microsoft developed a unique relationship that paved the way for advancements in the nascent personal computer industry, and subsequent advancements in personal computing.

Following the first DOS-based version of Microsoft Word in 1983, Word for Windows launched in 1989 and become a huge hit for the company. It generated over half the revenue of the worldwide word-processing market, according to Microsoft.

"Thanks to the Computer History Museum, these important pieces of source code will be preserved and made available to the community for historical and technical scholarship," a company said in a statement.

It's enough to make us want to find our old 5.25-inch floppy drives and green CRT monitors.

What's Wrong With Apple's iOS 7.1

• A New Phone Interface

  

  The most striking visual change is the telephone interface. Although the circular number key pads remain, the large square "call" button has been replaced by a small circle displaying a phone icon.

• Hunt and Peck?

  

  Those phone call interface changes have been carried over to the answer/decline screens as well. Now when your receive an incoming call, the screen will display two simple red and green button icons, instead of the large "answer" and "decline" button blocks in the previous version.

  This change seems more like a designer flourish rather than a practical move, as hitting those large call/answer/decline buttons on the iPhone's touchscreen while carrying bags or multitasking is certainly easier than having to now aim for the tiny circles.

• Touch ID & Passcode

  

  In addition to boosting the accuracy of the iPhone 5S Touch ID system, iOS 7.1 now gives the feature its own set-up menu in the Settings section. Not much has changed here, but it's a welcome update and it seems a bit odd that Apple didn't give Touch ID its own menu section from the very beginning.

• Wallpapers Without the Motion Sickness

  

  When iOS 7 first debuted, one of the biggest complaints revolved around the parallax effect in Wallpaper, a dynamic that caused some prone to motion sickness to avoid the feature altogether. With iOS 7.1, Apple has included a handy "perspective on/off" option when selecting a new Wallpaper image.

  The feature also offers those who are fans of the feature a quicker way to test out how certain images will look with the effect before selecting that image as a new Wallpaper image.

• Siri Gets a Little More Human

  

  The voice of Siri for U.S. users remains the same, but some international users will notice a warmer, more human-sounding digital assistant after upgrading to iOS 7.1. In particular, the British English and the Japanese voices of Siri offer noticeably warmer, less robotic sounding version of Siri. This "more human" touch has also been applied to the Australian English and Mandarin Chinese versions of Siri.

• Weather and Calendar Enhanced

  

  Another minor tweak to iOS comes in the operating system's Calendar and Weather apps. The new Calendar features a handy option that allows you to show special events and appointments right under the calendar view.

  On the Weather app, the weather condition icons are now filled in, offering the viewer an easier image to process visually when quickly glancing at weather conditions during transit.

Potential Problems

Bluetooth Connectivity

It's still early days, but some users are reporting problems connecting to Bluetooth devices after the 7.1 update. We tested the connection on our own iPhone 5S and we were also unable to discover fully powered Bluetooth device in our vicinity.

This is a potentially huge issue — considering many iOS users rely on Bluetooth devices such as keyboards and headsets.

iBeacon

One new behavior in iBeacon, first discovered by BEEKn, is being touted by some as an enhancement. But based on that description, it could just as well be deemed a problem.

According to the report, iOS 7.1 now allows your device to continue to discover iBeacon points after you've closed an iBeacon-enabled app. This continues to work as long as Location Services are turned on — even if you restart your phone.

Hello there, Welcome to our blog. How you all are, Hope you all doing great. On our blog you will find support for tech, hacking and social tweaks. We provide networking solutions for any type of problem. You can contact us through this blog. We will do whatever we can do for your problem. 

Have you checked our previous few tutorials about VLSM, Classful networking and much more. If not please check. Hope you would enjoy reading here.

Now let's talk about compatibility. May be if you have ever built any app or website if you don't make it browser compatibility then it means that if your website is running good in chrome but when you will open it in mozilla firefox, definitely your website will not be opened at all or it may display everything humble jumble you know. So you must know how to make your app or websites browser compatibility.

Below is a curated list of both free and premium cross-browser testing tools, ranging from cloud platforms to desktop applications. These tools will help you easily test everything from versions of Internet Explorer versions to more than 300 modern browser combinations.

1.Ghostlab

Ghostlab offers synchronized testing for scrolls, clicks, reloads and form input across all your connected devices, meaning you can test the entire user experience, not just a simple page. Using the superior built-in inspector, you can discover and fix problems quickly, connected to the DOM or JavaScript output on any device.

2. Browser Stack

Browser Stack provides live, web-based browser testing with instant access to every desktop and mobile browser (currently more than 300), with the ability to test local and internal servers, providing a secure setup. The cloud-based access means no installation is required, and the pre-installed developer tools (including Firebug Lite, Microsoft Script Debugger and many more) are useful for quick cross-browser testing and debugging.

The Secret to Password Security

Have you check about last article 'Look Back' Videos for Deceased Users.Have you heard about, facebook has overtaken whatsapp. What you think out of it. Hello, there, facebook is using whatsapp. :) :) Check out articles at our blog.

In this tutorial i'm going to something about password. Hope you would like it. here we go:

The Secret to Password Security Could Lie in Your Social Network

it's midnight and you're soothing your insomnia by purchasing a pair of shoes on a daily deals website. You click through to the checkout page only to find you can't connect your PayPal account; you'll have to input your credit card data manually and create a new username and password for this little-known site you're not sure you'll ever use again. So you roll your eyes and type in the same password you've used for PayPal, Amazon and a host of other shopping sites.

There's a term for that feeling: password fatigue.

In a hackable world, password fatigue can have dire consequences. The difficulty of remembering dozens of unique and complex passwords leads us to make short, overly simple ones instead, or to use one password for a number of different websites. This can be devastating, if just one of these sites is hacked.

Forbes and Kickstarter are the latest high-profile websites to experience password breaches. Cyber security experts find it unsettling that, despite the sharp increase in hacking incidences, many websites have not added safeguards, such as multi-factor authentication to their login procedures.

Such behavior flies in the face of mounting evidence that passwords alone — even really good ones — cannot sufficiently protect us anymore.

The good news is that two-factor authentication can safeguard the majority of hacking targets, and soon, the precious personal data you've been sharing with your social network could help you ward off hackers, too.

In this 2002 photo, a computer screen shows a password attack in progress at the Norwich University computer security training program in Northfield, Vt. On Wednesday, Dec. 4, 2013, passwords for more than 2 million Facebook, Google and other accounts were compromised and circulated online.

"We've all been through the process of verifying ourselves to a bank on the phone or on the web, where you give your mom's mother's maiden name or the place you were born," says Stephen Ufford, founder and CEO of Vancouver-based identity-verification platform Trulioo. "That information is from public records and it's become a lot more easy to obtain these days because of the Internet."

The solution to these "secret questions" could be to leverage social data, gleaned not only from Facebook and Twitter but from other mobile apps, that would be less readily accessible to hackers.

Facebook is already employing a form of this social verification: When you log in to the platform from an unknown computer, the site will ask you to identify the names and faces of several of your friends. That kind of data is much more secure than your mother's maiden name; it would be difficult for a hacker half a world away to determine this information in the space of a few minutes.

Cyber security experts tend to agree that in the future, password security will rely on adding even more authentication factors to the mix. The methods by which multi-factor authentication will evolve, however, are disputed. Some see biometrics as a potentially secure method of password authentication (How could someone copy your heartbeat, after all?), while others advise extreme caution in moving forward with biometry.

"Biometry is uniquely personal data that cannot be changed. What happens when that fingerprint gets released out into the public?"

"Your fingerprint says a lot more about you as an individual than your GPS location," says Geoff Saunders, CEO of digital security startup LaunchKey. "Biometry is uniquely personal data that cannot be changed. What happens when that fingerprint gets released out into the public?" 

Experts propose offering a host of authentication factors, from the current standard of unique codes sent via SMS to fingerprint- or voice-identification software. From there, users can pick and choose the measures that suit them best. This would also safeguard the user in case one authentication factor is breached.

"Every user will have a choice of maybe five or six options, and they can pick the one that's comfortable or appropriate for that type of communication," predicts Neal O'Farrell, executive director of The Identity Theft Council, a California-based group that works with local law enforcement to provide counseling to identity theft victims. "So for example, if you're on a cellphone with poor reception, voice authentication might not work. A fingerprint might work there. Social verification might work there. That's the only way we're going to overcome consumer resistance to particular types of authentication."

Social networks and the data contained within smartphones and mobile apps can also help with traditional identity vetting procedures, for instance when applying for a loan or for a passport online.

"A lot of the traditional means of establishing identity don't work for every segment of the population," says Jeremy Grant of the National Strategy for Trusted Identities in Cyberspace(NSTIC). "Picture your classic 18-year-old, who might need to be identity-proofed but doesn't have a credit card, doesn't have a cellphone in their own name — not a lot out there in terms of history to score. But they might have a Twitter or Facebook account with several hundred friends."

Grant cautions that social networks cannot be the ultimate authority in identity vetting or bolstering password security, but that they can act as one factor in a layered identity-proofing process. "There are new data points about people online that may be helpful in establishing the person is not just a made-up identity, and that they're actually the person they claim to be," he says.

In 2004, AOL Inc. became the first major online business in the U.S. to embrace a second layer of password authentication, giving subscribers a matchbook-size device with a six-digit code that was required to access their accounts.

The future of social network verification sharply diverges into two separate paths: that of total anonymity or of total immersion in your data.

On the anonymity front, LaunchKey offers passwordless, multi-factor authentication software that doesn't gather or store any of your personal data. Its authentication factors include a PIN or "combination" lock, as well as the ability to pair devices together — for example, making it impossible to log in to your work computer without also having your mobile phone nearby — and geo-fencing, which entails setting a geographical radius for logins. None of these relies on personal data beyond an individual's location.

"We firmly believe that you can authenticate an individual without knowing anything personal about them," says Saunders.

LaunchKey is also experimenting with "social vouching" as a form of authentication, particularly in business settings. Essentially, this means having other people in your immediate surroundings confirm your identity when you attempt to access a device.

"There might not be anything stronger as a factor of authentication than someone vouching for someone else," Saunders says. "Vouching can be done not just directly — meaning you ask me to vouch for you, and I do that — but can also be done passively. We can track where different devices are and have those devices communicate with each other to ensure that they maintain a proximity."

The same sort of thing could theoretically be done with friends on social networks — an entirely unexplored territory, according to Grant and Saunders — although it may require too much of a sacrifice in terms of time and convenience.

Unlike LaunchKey, however, most enterprises are not in the business of preserving your anonymity. The data that your social networks and mobile apps are already gathering (tons and tons of it) can also be leveraged as an authentication system. The type of facial recognition technology that Facebook employs could potentially be used for interactions outside of a social network.

'Where do we normally find you at 7 a.m. on Tuesdays?'

The benefit of leveraging social network data as a security measure, according to Ufford, is that security questions no longer have static, unchanging answers like your mother's maiden name — and therefore are more difficult for a hacker to learn. "If you go to the gym all the time and you have five apps on your phone tracking your locations, it's very conceivable that one of these questions would be, Where do we normally find you at 7 a.m. on Tuesdays?'" Ufford says. "That's really hard for someone in Nigeria to know.

The advantage lies in the dynamism of that information, Ufford explains. "If you move to New York from San Francisco, you might end up going to a new place, and that data can be changed."

Despite living in a post-Edward Snowden world, many social network users continue to upload highly personal tidbits readily accessible not just to Facebook but, potentially, to government organizations. It's a small concession, then, that all this data could potentially be used to protect you as well as incriminate you.

"One of the side effects [of social verification] should be that it's going to reveal just how much companies like Facebook and Google gather about you and your circle, but most consumers won't pay it a second thought," says Farrell. "You're willing to trade a little bit of privacy for a little more security. People will still make that trade-off."
