HISTORY OF HACKING

The first bona fide appearance of a computer hacker occurs nearly 100 years later, in the

1960s. A “hack” has always been a kind of shortcut or modification a way to by pass or rework

the standard operation of an object or system. In fact, the most elegant and enduring hack from this

period is the UNIX operating system, developed in the late 1960s by “Dennis Ritchie” and “Keith

Thompson” of Bell Laboratory. The 1970s produced another type of hacker , one focused on

telephone systems known as “ phreakers ”, these hackers discovered and exploited operational

characteristics of the newly all electronic telephone switching network that enabled them to make

long distance calls free of charge. Modems, devices that enabled computers to communicate with

each other over telephone lines, were also more widely available and significantly extended the

hacker‟s reach.

Sniffing is the use of a network interface to receive data not intended for the machine in which the

interface resides. A variety of types of machines need to have this capability. A token-ring bridge, for

example, typically has two network interfaces that normally receive all packets traveling on the media on

one interface and retransmit some, but not all, of these packets on the other interface. Another example

of a device that incorporates sniffing is one typically marketed as a “network analyzer”. In the united

States, script kiddies are less serious crackers are thought to be between 12 and 30 years old. This

new breed of “hacker” directed its knowledge towards distinctly criminal pursuits including the

distribution of pirated, commercial software, games, computer viruses and worms that could virtually

shut down systems. The number of popular books and films at this time, beginning with 1983‟s movie,

War Games. Nowadays the hackers are growing all over the world be careful guys.

YOUR SMARTPHONE AS A 3D SCANNER

3D scanning aims to capture the geometry of the 3D world. However, most existing solutions

require a complicated setup, are often hard to use and might not always work outdoors.

Marc Pollefeys, professor at the Institute for Visual Computing and his group found a way to

develop a software that works with existing smartphone technology that allows the user to scan a

3D model almost as easy as taking a photograph. The technology was demonstrated publicly for

the first time today at the International Conference on Computer Vision in Sydney,Australia.

As all calculations are performed directly on the phone, the user gets immediate feedback and

can select additional viewpoints to cover missing parts of the 3D model. "This is an important

advantage compared to solutions that batch process all the images in the cloud at a later time",

explains Marc Pollefeys.

The app also makes it possible to visualise the state of the 3D scan from different viewing angles,

allowing the user to cover all the areas of the object he is interested in. Having a solution on a

mobile phone enables the acquisition of 3D scans on-the-fly anywhere. The approach works in a

wide variety of settings, including low-light conditi-ons such as inside a museum.

After the 3D capture is started, the system automatically determines the correct moments to

extract camera images based on the user motion. "Only two years ago, such a software only run

on massive computers. We were able to shrink processes down on smartphone level and make

them highly efficient", says Marc Pollefeys.

Contrary to image-only 3D capture solutions the app is able to determine the absolute size of the

scanned 3D object, as well as the vertical direction. Because of the complexity of the calculations

needed to reconstruct hundreds of thousands of points, the graphics co-processor (GPU) of the

phone is used to enable a faster reconstruction and increase interactivity for the user.

3

The technology also allows the 3D capture of faces, giving a third dimension to portraits, profile

pictures or images of loved ones. Having a convenient way of getting 3D models of everyday

objects, users will now be able to copy real-world objects by scanning a full 360 degree model of

an object. The resulting 3D model can be used for visualisation or augmented reality

applications, or even be used for 3D printing, potentially at a remote location, effectively

enabling the user to replicate an object.

APPLE GIVING AWAY IWORK FOR FREE WITH IOS DEVICES

The application is Apple's version of MS Office.

Apple‟s iWork application suite will come for free with all new iOS 7-based devices.

This would be welcome news for iPhone fans since this application is a useful one and costs $5 to $10 at

the moment. The announcement is in fact somewhat a surprise from the company.

Apple‟s iWork consists of Pages and Numbers, which is the iOS counterpart of Microsoft‟s MS

Word and MS Excel. Apple‟s iWork also includes the iMovie, Keynote and iPhoto applications. These

apps are amongst the most useful and popular applications on Apple as the cover almost all the basic

office needs that users can have. “With one touch, boom, all five of these apps are downloaded for you,

and some additional ones,” “We think that iWork is a really key advantage for a customer‟s productivity

and that iPhoto and iMovie are great for their creativity,”he added. The apps have all been made free for

all new iOS devices. This means that users, who are now buying iPads, iPhones and the fifth generation

models of the iPod Touch, will all get free access to these apps. It should generate a lot of interest

amongst the fans of the company to use these services more avidly.

DELL TO ADD CHROMEBOOK 11, LOOKS BEYOND WINDOWS AND

ANDROID

Dell joins growing market for thin-and-light Chrome OS laptops, but will initially ship

Chromebook 11 only to educational institutions Dell said it would join a growing market of thin-and-

light Chrome OS laptops with the new Chromebook 11, but the system will initially be available only to

educational institutions. The company did not provide specifications for the laptop, but in an email said

more Chromebooks will be announced for "budget-strapped" small-and-medium business and consumers

in the coming months. Dell did not provide a shipping date for the Chromebook 11.

PC makers and Google are promoting Chromebooks , which are low-cost laptops for those who

do most of their computing on the Web. Dell already offers Android tablets starting at $149, and laptops

and tablets based on Windows. A new wave of Chromebooks hit the market in October from Acer,

Hewlett-Packard and Samsung. Laptops with 11.6-inch screens include Acer's $199 Chromebook C720,

Hewlett-Packard and Google's $279 Chromebook 11, and the $249 Samsung Chromebook.

Hewlett-Packard also sells a $299 Chromebook 14 with a 14-inch screen. Acer's $299

Chromebook C720P, which started shipping a few days ago, has an 11.6-inch touchscreen. Chromebooks

have processor options of either ARM or Intel's Celeron, which is based on a Haswell microarchitecture.

Depending on the screen size and processor, Chromebooks can offer more than six hours of battery life.

Many Chromebooks have minimal storage of just 16GB, but come with two years of 100GB of free

cloud storage on Google Drive.

STEAMOS

Steam is coming to a new operating system

As we‟ve been working on bringing Steam to the living room, we‟ve come to the conclusion that

then environment best suited to delivering value to customers is an operating system built around Steam

itself. SteamOS combines the rock-solid architecture of Linux with a gaming experience built for the big

screen.It will be available soon as a free stand-alone operating system for living room machines.

Fast forward

In SteamOS, we have achieved significant performance increases in graphics processing, and

we‟re now targeting audio performance and reductions in input latency at the operating system level.

Game developers are already taking advantage of these gains as they target SteamOS for their new

releases.

Cooperating system

Steam is not a one-way content broadcast channel, it‟s a collaborative many-to-many

entertainment platform, in which each participant is a multiplier of the experience for everyone else.

With SteamOS, “openness” means that the hardware industry can iterate in the living room at a much

faster pace than they‟ve been able to. Content creators can connect directly to their customers. Users can

alter or replace any part of the software or hardware they want. Ga mers are empowered to join in the

creation of the games they love.

In-home Streaming

You can play all your Windows and Mac games on your SteamOS machine, too. Just turn on

your existing computer and run Steam as you always have - then your SteamOS machine can stream

those games over your home network straight to your TV!

Worldwide

Steam is in 185 countries and has been translated into 25 languages. Truly global platform, Steam

and now SteamOS, brings entertainment to an audience without borders.

GUARDIAN

Tech major Microsoft on Thursday launched „Guardian,‟ a new safety application (app), that

enables friends and family of Windows Phone users to track them in real time. Available exclusively for

Windows Phone users, Guardian‟s „track me‟ feature allows friends and family to track them using

Microsoft Windows Azure cloud services and Bing Map APIs, a statement issued by Microsoft here said.

Microsoft Launches New Safety Application

“Guardian users can call for help through an „SOS‟ alert button and also connect to security

agencies, police and hospitals easily via this app in times of distress,” the statement said. Guardian was

developed over six months by a group of enthusiastic Microsoft employees in India, within the Microsoft

Garage, a global employee innovation initiative that g ives the employees an outlet to explore ideas. “Our

employees wanted to do something to enable people to feel safer in our cities. So they used their spare

time to develop Guardian,” Managing Director of Microsoft IT India Raj Biyani said in a statement.

Guardian is a robust personal security app with more safety features and capabilities than any other

comparable app available to Indian smartphone users today, he claimed.

To use Guardian effectively, users need to add the names of friends, family members and security

groups to the settings. In an emergency situation, the app can be used to alert them, via the SOS button.

All the user has to do is tap the SOS button. The phone then sends a distress SMS to all buddy mobiles,

notifying them of the emergency along with location details, Microsoft said. “At the same time, the SOS

button also sends emails to buddy email IDs and posts to private Facebook groups, if registered.”

Pointing out that Guardian uses Microsoft Windows Azure cloud services and Bing Map APIs

extensively and can help the authorities and medical teams track the user, the statement said the phone

can be traced even if it is broken.

NEXT GENERATION COMPILER OF MICRO SOFT

Microsoft execs also showed off without using the codename a new technology in development

for compiling directly .Net code to native code. That technology, from what I've heard from my sources,

is codenamed "Project N."

Microsoft Project Manager Orville McDonald showed a quick demonstration during the Visual

Studio launch of two different versions of Microsoft's FreshPaint app running on Microsoft Surface

tablets. One of the versions made use of unspecified optimization technology that caused the application

launch and run more quickly than the version without. McDonald said the faster version used an

experimental technology in development at Microsoft that involved the ability to compile .Net code to

native code directly.

We don't do JIT (just-in-time compile) and use optimization that we use for C++ code,"

McDonald told the audience. He said at some point in the future, Microsoft planned to make this

technology available to the wider development community. I've gotten a few tips in recent months about

"Project N," which, according to my contacts, is designed to make applications developed in .Net/C#

work better on Windows 8 and Windows RT via new compiler technology under development at the

company. My tipsters have said Microsoft is planning to go public with its Project N plans in 2014.

It's not clear exactly how this new compilation technology will manifest. It could be something

that Microsoft uses internally on the back-end, Microsoft to compile apps submitted by Windows

developers before they are made available in the Windows Store.Microsoft already has done work

around improving compilation of Windows Phone apps involving Machine Dependent Intermediate

Language (MDIL).

CHROMEBOOKS' SUCCESS PUNCHES MICROSOFT IN THE GUT

Chromebooks had a very good year, according to retailer Amazon.com and industry analysts

and that's bad news for Microsoft.

The pared-down laptops powered by Google's browser-based Chrome OS have surfaced this

year as a threat to "Wintel," the Microsoft-Intel oligarchy that has dominated the personal-

computer space for decades with Windows machines.

As of late Thursday, the trio retained their lock on the top three places on Amazon's best-

selling-laptop list in the order of Acer, Samsung and Asus. Another Acer Chromebook, one

that sports 32GB of on-board storage space -- double the 16GB of Acer's lower-priced

model -- held the No. 7 spot on the retailer's top 10.

Chromebooks' holiday success at Amazon was duplicated elsewhere during the year,

according to the NPD Group, which tracked U.S. PC sales to commercial buyers such as

businesses, schools, government and other organizations.

NPD's tallies, Chromebooks accounted for 21% of all U.S. commercial notebook sales in

2013 through November, and 10% of all computers and tablets. Both shares were up

massively from 2012; last year, Chromebooks accounted for an almost-invisible two-tenths

of one percent of all computer and tablet sales.

Stephen Baker of NPD pointed out what others had said previously: Chromebooks have

capitalized on Microsoft's stumble with Windows 8. "Tepid Windows PC sales allowed

brands with a focus on alternative form factors or operating systems, like Apple and

Samsung, to capture significant share of a market traditionally dominated by Windows

devices," Baker said in a Monday statement.

CAKEWALK SONAR X3

Cakewalk SONAR X3 ($149.99 list) may be the least expensive version of SONAR available, but it's no

cut-rate digital audio workstation software. In doing this review, it would be easy to look at all the things

taken out from the higher-end Studio and Producer versions of SONAR X3, and list them all as cons for

this product.

SETUP RECORDING AND INTERFACE:

For this review, I tested SONAR X3c on a Core i5-powered Lenovo ThinkPad running 64-bit Windows

7. As with the Producer and Studio versions, there's no copy protection the way there is with Pro Tools

and Cubase, which is a huge relief when using an ultrabook or other laptop with few USB ports

The modular Skylight user interface is a gem, and one of the best things about the entire SONAR lineup.

It manages to stay reasonably uncluttered and attractive, while simultaneously letting you do everything

you need to do arranging, and mixing, depending on how you lay out the windows.

EDITING TOOLS:

As before, the Control Bar at the top contains oversized track control buttons and easy access to the

metronome, recording resolution, tempo, and meter. You can expand t he control bar to add sections for

loop recording, editing, and other features; and you can set the bar to float as well as stay affixed to the

top.

One of the new signature features in SONAR X3 is the comping tool, which lets you assemble the

perfect track from a series of take lanes. Each time you record, it creates a new lane. A special mode lets

you quick comp without the mouse; just hit shift and the space bar and you can toggle between the

various tracks using the arrow keys.

CHINA OPERATING SYSTEM FOR SMARTPHONE

IT BULLETIN DATE: 24-01-2014

China, wary of operating systems from the Western world, has built a new smartphone OS that it

believes will be more secure than the likes of Android and the iPhone. While China claims it as its

own, the OS looks like it's based on Android.

China Operating System, or COS, was unveiled last week by the Chinese Academy of Sciences

and the Shanghai-based Liantong Network Communications Technology, the New York Times

reported. COS is "designed for use on many devices including smartphones and personal

computers" and was called "a strategic product for national security," the Times said. US

surveillance and the end of support for Windows XP reportedly played a role in the system's

creation. Liantong Deputy GM Chen Feili said the ultimate goal is to make COS China's main

operating system.

While Windows is the predominant desktop OS in China, Android commands about 90 percent of

China's smartphone market, with iOS taking most of the rest, IDC reports.

Despite that, Chinese officials say it was developed "completely" by China. An article published

by the Chinese Academy of Sciences "said existing open-source operating systems pose security

risks, and foreign-made systems have 'acclimatization' difficulties in China, problems that COS

addresses," the Times wrote.

COS reportedly runs Java applications, supports HTML5 websites and games, and is compatible

with more than 100,000 applications overall.

China's claims about COS' origins raised suspicion, the Times reported:

Separately, the Chinese government signed a deal with Canonical last year to create a new version

of the open source Ubuntu for Chinese users that is intended to wean people off of Windows

desktops. At the time, Canonical said that "future work will extend beyond the desktop to other

platforms" such as servers, tablets, and phones. A recent financial report from Canonical said that

China accounts for the "majority of global units shipped" by the company.

POWER TO THE PORTABLE: 3 HIGH-PERFORMANCE MOBILE

WORKSTATIONS

Computerworld - Sales of PCs have fallen by 11% since 2012, according to statistics compiled

by Gartner analysts. However, there is one niche market that is still doing well: mobile workstations.

This category has seen an upsurge with increasing sales."It's been doom and gloom for PCs for several

years," observes Lloyd Cohen, director of market analysis at IDC. "But it's been anything but declines for

mobile workstations. It's the bright spot of the computer business, with sales growth of 5% a year and

lots of new systems available."They can be used for a var iety of graphics-heavy applications: geological

simulation software that peers 3,000 feet under an oil drilling rig; architectural software that virtually

moves a wall on a floor plan at a construction site; or special effects software used to alter a sequence on

a film set.

From the outside, a mobile workstation looks like any other lalptop. But "look inside," says

Cohen, "and you see that these are machines that excel at graphics and computation. They have the best

of everything." This can include a Core i7 processor, 16GB or more of system memory, the latest

graphics chips and at least 2GB of dedicated video RAM.Because they define the top shelf of the PC

business, mobile workstations can cost five times or more than a typical mainstream laptop. They are

also a throwback to a heavier and bulkier era of mobility. Mobile workstations can barely fit onto an

airline's economy class tray table and can weigh double that of a consumer laptop.

Eurocom Racer 3W:

Aiming for ultimate performance, Eurocom's Racer 3W spares no expense, leading to a mobile

workstation that can plow through the most complex graphic tasks The Eurocom Racer 3W includes the

most powerful mobile processor that Intel currently makes. The quad-core Core i7-4930MX cruises

along at 3.0GHz -- 300MHz faster than the HP or Toshiba systems -- and can punch up to 3.9GHz when

needed.

17

HP ZBook 15:

According to HP, the company is the leader in mobile workstations, with 42.5% of sales for the

second quarter of 2013. That may be because it offers laptops such as the ZBook 15, which is powerful

and well designed, and offers extras such as a Thunderbolt high-speed port for external drives.

Toshiba Tecra W50:

Although Toshiba is a newcomer to the mobile workstation market, its Tecra W50 can teach the

established players a thing or two about delivering a thin and light system on a tight budget (the base unit

starts at $1,899; the review unit costs $1,999). Unfortunately, it lacks the configuration options that the

others have.

WINDOWS 8 MARKET SHARE SURPASSES ALL VERSIONS OF OS X

COMBINED

According to Net Applications, Windows 8 has achieved a milestone in the month of August,

overtaking the market share of all Microsoft's latest operating system gained 2.01 percentage points in

August to end with 7.41% of the market, allowing it to gain a narrow lead on Mac OS X, which posted a

market share of 7.28%.

The growth Windows 8 experienced in August was the largest month-on-month gain since its

launch in October last year, although it's not quite clear what sparked the sudden influx of upgrades. It

could perhaps be related to the price cuts of Microsoft's Surface RT and Surface pro tablets, or the leaks

of the Windows 8.1 RTM, or simply a large amount of mid-year system purchases.

Market Share July 2013 Market Share Market Share Gain

Windows 8 7.41% 5.40% 2.01%

Windows 7 45.63% 44.46% 1.14%

Windows XP 33.66% 37.19% -3.53%

Windows Other 0.38% 0.27% 0.11%

Windows 7 also saw a gain of 1.14% in August, while Windows Vista and Windows XP declined by

0.13 and 3.53 percent respectively. Overall, Windows saw a fractional decline of 0.37% in the month.

Despite gains for Windows 8 in August, it seems Microsoft hasn't been able to convince a large number

of Windows 7 users to upgrade. The launch of Windows 8.1 later this year, which addresses a number

complaints surrounding Windows 8, may prompt more users to upgrade their OS, but at least for now it

seems Windows 7 and Windows XP will remain kings of the market.

NOKIA LUMIA 620

The Nokia Lumia 620 is a Smartphone designed, developed and marketed by Nokia. It is the

successor to the Lumia 610, and is one of the first Nokia phones to implement Windows Phone 8

alongside the Nokia Lumia 920 and Nokia Lumia 820. Although sharing a similar name with the Lumia

610, the Lumia 620 is a major overhaul over its predecessor, employing a 1.0 GHz dual-core processor.

It was announced in December 2012 and started selling in January 2013 in Asia, followed by Europe and

the Middle East at an estimated street price of USD 249. In the United States, the Nokia Lumia 620 is

available for AT&T's subsidiary brand Aio Wireless.

Like other Lumia devices with Windows Phone 8, Nokia adds these applications: HERE Drive+,

HERE Maps, HERE City Lens, Nokia Mix Radio(select markets), Smartshoot, NokiaCinemagraph. On

July 23, 2013, a variant of the Nokia Lumia 620, the Nokia Lumia 625, was released with a bigger

display and 4G support. Along with Lumia 810 and 928, this model will not get the FM Radio support

upon updating to Windows Phone "Amber". Reasons range from the model not having the FM radio chip

to the design of the casing(and earphone plug) not supporting the connection for the antenna required.

MICROSOFT SURFACE

The Surface debuted in two models, marketed as Surface RT and Surface Pro. Surface RT uses

an ARM (ARMv7) CPU running Windows RT whereas Surface Pro utilizes an Intel Ivy Bridge CPU

running Windows 8. The Surface devices use a molded magnesium casing known as "VaporMg"

(pronounced "VaporMag") that houses Surface's components paired with a PVD finish.A built-in

kickstand allows the device to be propped up for viewing without any additional hardware.For ports,

Surface RT features a full-size USB 2.0 port, an HD video out port, and a microSDXC card slot; Surface

Pro includes a full-size USB 3.0 port, Mini DisplayPort port, and microSDXC card slot. Both models

have two 720p HD front- and rear-facing cameras, and a 0.77 millimetres (0.030 in)-thick kickstand

which allows the device to be stood up at an angle for hands-free viewing.

Display

Surface RT and Surface Pro have screens of 10.6 inches (27 cm) with a 16:9 aspect ratio. Both

tablets use Microsoft's ClearType HD display technology and support an ultra-wide viewing angle and

auto-adjusting screen intensity. In announcement talk, Michael Angiulo said that when Surface Pro is

held at 17 inches (43 cm), the eyes will not be able to distinguish between individual pixels. Both screens

feature Gorilla Glass, scratch and crack-resistant glass. The display functions as a multi-touch input

device. While Surface RT includes 5-point capacitive touch, Surface Pro includes 10-points of touch

detection. In addition, Surface Pro includes a digital pen and Wacom digitizing technology. This allows

the pen to be contacted with up to 1024 levels of pressure sensitivity. To achieve highly precise pen

inputs, the display produces a weak electromagnetic

UBUNTU OS

Ubuntu is a Debian-based Linux operating system, with Unity as its default desktop environment

(formerly GNOME). It is based on free software and named after the Southern African philosophy of

ubuntu (literally, "human-ness"), which often is translated as "humanity towards others" or "the belief in

a universal bond of sharing that connects all humanity".

Features:

Ubuntu is composed of many software packages, the majority of which are free software. Free

software gives users the freedom to study, adapt/modify, and distribute it. Ubuntu can also run

proprietary software. Ubuntu comes installed with a wide range of software that includes LibreOffice,

Firefox, Empathy, Transmission, and several lightweight games (such as Sudoku and chess). Additional

software that is not installed by default (including software that used to be in the default installation such

as Evolution, GIMP, Pidgin, and Synaptic) can be downloaded and installed using the Ubuntu Software

Center or other APT-based package management tools. Programs in the Software Center are mostly free,

but there are also priced products, including applications and magazines. Ubuntu can also run many

programs designed for Microsoft Windows (such as Microsoft Office), through Wine or using a Virtual

Machine (such as VirtualBox or VMware Workstation). Ubuntu Desktop includes Unity, a graphical

desktop environment.

History and development process

Ubuntu is built on Debian's architecture and infrastructure, to provide Linux server, desktop,

phone, tablet and TV operating systems. Ubuntu releases updated versions predictably - every six months

- and that each release would receive free support for nine months (eighteen months prior to 13.04) with

security fixes, other high-impact bug fixes and very conservative, substantially beneficial low-risk bug

fixes.

22

Ubuntu Server:

A screenshot of the Ubuntu 12.04 Server installation boot menu.Ubuntu has a server edition that

uses the same APT repositories as the Ubuntu Desktop Edition. The differences between them are the

absence of an X Window environment in a default installation of the server edition (although one can

easily be installed including Unity, GNOME, KDE or XFCE) and the installation process. The server

edition uses a screen mode character-based interface for the installation, instead of a graphical

installation process.

ANDROID KITKAT

Android 4.4 is designed to run fast, smooth, and responsively on a much broader range of

devices than ever before — including on millions of entry-level devices around the world

that have as little as 512MB RAM.

KitKat stream lines every major component to reduce memory use and introduces new

APIs and tools to help you create innovative, responsive, memory-efficient applications.

OEMs building the next generation of Android devices can take advantage of targeted

recommendations and options to run Android 4.4 efficiently, even on low-memory devices.

Dalvik JIT code cache tuning, kernel same page merging (KSM), swap to z RAM, and

other optimizations help manage memory. New configuration options let OEMs tune out-

of-memory levels for processes, set graphics cache sizes, control memory reclaim, and more

In Android itself, changes across the system improve memory management and reduce

memory footprint. Core system processes are trimmed to use less heap, and they now

more aggressively protect system memory from apps consuming large amounts of RAM.

For developers, Android 4.4 helps you deliver apps that are efficient and responsive on all

devices. A new API, Activity Manager is Low Ram Device(), lets you tune your app's

behavior to match the device's memory configuration.

24

You can modify or disable large -memory features as needed, depending on the use -cases

you want to support on entry-level devices.

New tools give also give you powerful insight into your app's memory use. The procstats

tool details memory use over time, with run times and memory footprint for foreground

apps and background services. The meminfo tool is enhanced to make it easier to spot

memory trends and issues, and it reveals additional memory overhead that hasn't

previously been visible.
