The new Chief Executive Officer of Microsoft Corp

2014-02-05T09:11:00.002-08:00

In India, Satya Nadella showed inquisitive streak

Nadella’s elevation to the top spot at Microsoft would end a five-month search for a tech-savvy heavy-hitter to lead the company co-founded by Bill Gates

In his university days in India, Satya Nadella, the new chief executive officer of Microsoft Corp, was a relentless questioner. “When all other students will quietly listen to what I would teach, he will ask a lot of questions - 'why does it have to be like this, why can't we do it like this?'," said Harishchandra Hebbar, who taught digital electronics to Nadella at Manipal University.

"Sometimes it felt like he was just testing my patience," said Hebbar, laughing. That questioning nature has served Nadella well in his 22-year career at Microsoft, the world's largest software company. Last year he was promoted to run the company's fast-expanding cloud, or Internet-based, computing initiatives.

His elevation to the top spot at Microsoft would end a five-month search for a tech-savvy heavy-hitter to lead the company co-founded by Bill Gates. Nadella grew up in Hyderabad, a technology hub that is home to the biggest Microsoft research and development centre outside of the United States.

Nadella is Microsoft CEO

His father was a member of the elite Indian Administrative Service and a member of the Planning Commission during 2004-2009 under Prime Minister Manmohan Singh. His father, B. N. Yugandhar, who still lives in Hyderabad, declined to speak with Reuters when reached by phone.

Born in 1967, Nadella attended the prestigious Hyderabad Public School, where he met his future wife. Nadella studied electronics and communication engineering, at Manipal University, where people who knew him at the time described him as friendly, modest and well-spoken.

Manipal is a mid-ranking private institution, and does not have the cachet of the elite Indian Institute of Technology (IIT) and Indian Institute of Management (IIM) where many of India's global power players were educated.

As the CEO of Microsoft, Nadella joins the growing list of Indian-born executives to head a major global corporation. They already include PepsiCo Inc CEO Indra Nooyi and Deutsche Bank co-CEO Anshu Jain. After graduating in 1988, Nadella, like many ambitious Indians, moved to the United States to study, earning a master's degree in computer science from the University of Wisconsin-Milwaukee.

Friends recall Satya Nadella as social, affable and focused

Ganesh Prasad, a classmate of Nadella at Manipal who remains in touch with him, recalled a conversation in 1991 when Nadella was working at Sun Microsystems. "We were having a conversation and talking about Sun as the future of hardware and he was like: 'you know where I need to go? I need to be in software and I need to be in marketing and I need to be in Microsoft'," Prasad recalled by phone from Bangalore, where he now lives.

Prasad, who worked for 20 years in the United States with Intel Inc, said Nadella started with a base in technology and then became interested in how to market it - a skill set that will be called upon in his new role. By comparison, Microsoft's previous CEO, Steve Ballmer, was regarded more as a salesman and cheerleader than a technology visionary.

"While he comes from a very strong technology background, his outlook over the years has changed to: 'so, what, what am I going to do with this thing? How do I position it? How do I make sense of it all?'," said Prasad.

Computer Architecture of 8085 Microprocessor

Written by Abin August 21, 2012

Abin-TechnoHelp

A microprocessor is an electronic device that reads instructions from memory, accepts binary data and provides output after processing data according to the instructions. You can say its function is just like human brain.Basically microprocessor consists of three important units: input unit, output unit and a memory unit. 8085 is a 8-bit microprocessor. Here the data is usually 8 bit and the address is 16 bit. Let’s analyze the each and every components of 8085 microprocessor.

1) Register section
2) ALU
3) The buses
4) Timing & Control unit

1) Register section:
It consists of number of registers for storing data and addresses. It can be of two types:
a) General purpose registers
b) Special purpose registers

General purpose registers are used for temporary storage of data or address during execution. They are B, C, D, E, H and L. They are all 8 bit registers. So, to store 16 bit data we have to form a register pair like: BC, DE or HL.

Special purpose registers:

The following registers come under this category and each performing a special function.
Accumulator (A) – It is a 8 bit register which is used for storing the operands/data during execution.

Program counter (PC) – It is a 16 bit register used to store the memory address of the next instruction to be executed.

Index register – This is used for addressing index addressing mode.

Status register – It stores the present status of the microprocessor after any arithmetic and logical operation. It records any occurrence of carry, auxiliary carry, sign, zero and odd/even parity.

Stack pointer – It is a 16 bit register used to initialize the stack.

Instruction register – It is a 8 bit register that stores the instruction fetched from memory

2) Arithmetic and Logical Unit (ALU):It performs arithmetic and logical operations. Addition, subtraction, multiplication, division, AND, OR, XOR, NOT, shift and rotate operations are done by ALU.

3) The Buses:
It is the interface section for communication between processor and external devices. There are 3 buses

a)    Address bus – It carries the address of the instruction. It is 16 bit wide and unidirectional.
b)    Data bus – It carries data between external devices and processor. It is 8 bit wide and bidirectional.
c)    Control bus – It is used to send control signals to different units of microprocessor.

4) Timing & Control unit:
It generates the clock signals and control signals for communication between processor and peripheral devices.

TeamViewer

2012-08-21T10:52:00.001-07:00

TeamViewer

TeamViewer is a proprietary computer software package for remote control, desktop sharing, online meetings, web conferencing and file transfer between computers. The software operates with the Microsoft Windows, Mac OS X, Linux, iOS, and Android operating systems. It is possible to access a machine running TeamViewer with a web browser.While the main focus of the application is remote control of computers, collaboration and presentation features are included.

TeamViewer GmbH was founded in 2005 in Uhingen, Germany. TeamViewer is now owned by GFI.

Establishing connections

TeamViewer may be installed with an installation procedure, although the 'Quick Support' version will run without installation. To connect to another computer, TeamViewer has to be running on both machines. To install TeamViewer administrator access is required, but once installed it can be run by any user. When TeamViewer is started on a computer, it generates a partner ID and password (user-defined passwords are also supported). To establish a connection from a local client to a remote host machine, the local operator must communicate with the remote operator, request the ID and password, then enter these into the local TeamViewer.

To start an online meeting the presenter gives the Meeting ID to their participants. They join the meeting by using the TeamViewer full version or by logging on to http://go.teamviewer.com/ and enter the Meeting ID.

It is also possible to schedule a meeting in advance.

Linux port

TeamViewer for Linux is based upon the Windows version using Wine. Additionally, /opt/teamviewer/teamviewer/$tv_ver/bin/teamviewer contains links to a wrapper of a Windows executable:

export TV_BINDIR=/opt/teamviewer/teamviewer/$tv_ver/bin

exec "$TV_BINDIR"/wrapper "c:\Program Files\TeamViewer\Version$tv_ver\TeamViewer.exe" "$@"

Security

TeamViewer uses RSA private/public key exchange (1024-bit) and AES (256-bit) session encoding.

In the default configuration, TeamViewer uses one of the servers of TeamViewer.com to start the connection and the routing of traffic between the local client and the remote host machine. However in 70% of the cases after the handshake a direct connection via UDP or TCP is established.

Why Does Your Computer Shut Down

2012-08-04T01:08:00.000-07:00

Why Does Your Computer Shut Down

Your computer shuts down because of

1. Abnormal Temperature. Earlier your system was running smoothly, and now it’s not. You may have to check the temperature of your PC’s CPU. Make sure the fans run on your PC’s power and your CPU doesn’t grow warm.

2. Power Hiccup. If not, your PC may have shut down because of a power hiccup. You may say it’s a sudden surge of power that jolts your PC. This results in a lag—or your computer reboots, if not it goes into error mode. This is called the Blue Screen of Death. It’s not like final death as in oblivion—your computer can still recover your files, but expect them to be skewered. Imagine someone meeting a head-on collision with a ten-wheeler truck and comes out from a long coma. What you need is a UPS and a surge projector. Then go ahead and check the power cord in case you may have plugged it in half way.

3. Overheat. The least idea you can entertain is to think that your PC may be overheating, if not your motherboard has loose caps. When your system overheats because your CPU’s temperature goes berserk, your PC has auto power down feature– a least your PC does not catch fire.

4. Software censor. Or, you may not have installed a software that limits full access to your PC. Your PC’s overheating is caused by overuse, of course, so you can check your PC’s BIOS and monitor temps. Air out your unit. The most you can do is replace them with new ones, or buy a new motherboard.

You can put thermal paste on your PC’s CPU. You can also do a virus scan in case there are viruses and Trojans. In a heated PC, go to BIOs and press Supr. Check your mother board’s documentation and search for the recommended values.

How to troubleshoot computer shutdown

To resolve this issue, follow these steps:

Start your PC and go to Control Panel.
Then click Performance and Maintenance
Click on Power Options.
Click the APM tab.
Look for Enable Advanced Power Management Support and check the box
Then, click OK.

Some computers have an advanced configuration power interchange that shows completed message on the screen before your PC shuts down. If yours doesn’t have any, then you have to use one that has a HAL. PCs with ACPI have an ACPI-compliant basic input/output system or BIOS that allows your PC’s operating system to turn off its power supply automatically. But HAL is installed in computers that support APM only. The ones without this do not turn off even when you shut them down.

Windows 8

2012-08-04T00:22:00.000-07:00

The next operating system from Microsoft will be much more affordable than ever, according to a Monday's announcement.

When Windows 8 Pro becomes available, PC users will be able to upgrade at the cost of only $39.99, which is about a fifth of what people have to pay to upgrade to the current version of Windows. Windows Media Center could be added for free as a part of the deal.

"We set out to make it as easy as possible for everyone to upgrade to Windows 8," wrote Brandon LeBlanc on Blogging Windows.

"Starting at general availability, if your PC is running Windows XP, Windows Vista, or Windows 7 you will qualify to download an upgrade to Windows 8 Pro for just $39.99 in 131 markets," LeBlanc added.

Users will be able to purchase the upgrade at Windows.com later this year, and the Windows 8 Upgrade Assistant will help the process, including evaluation the readiness of the machine to step-by-step walk through. The new OS could be installed immediately or saved in .ISO file for a later use. The file could also be burned onto a DVD as well.

LeBlanc explained that the upgrade experience will be a "breeze".

Microsoft will also make a packaged DVD version for $69.99 during the promotion period, which will run through January 31, 2013.

Could this be Microsoft's attempt to close the gap between Apple's Mountain Lion operating system for desktop, who costs only $19.99 to upgrade? Or is it just a friendly gesture from the company to make it more easily acquirable?

In the mean time, the company is running another promotion where a person can get Windows 8 Pro for $14.99 by purchasing a Windows 7 PC.

How to find Mobile Location and provider ?

2012-07-28T12:32:00.003-07:00

How to find Mobile Location and provider ?

Dear all,
Today we are going to do some interesting things which are find mobile location with dot net.
Many time we got wrong number but we don’t know from where it comes with the help of this utility you are near about that location and service provider.
If you are not aware of mobile number system then it is too exciting for you just like me before I started this project.
Actually this utility not giving exact location but it gives the state and capital combination means near about that location you can find the mobile.
To understand the project we started with Mobile Number system.
The starting 4 number in any mobile number in India is pre decided by TRIA (Telecom Regulatory Authority of India).
This starting 4 number is called MSC code (Mobile Switching center).
This 4 number decide which provide giving his service to which area of India.
Here provider means IDEA, BSNL, AIRTEL etc.
As I got this information what I did I collect all the provider information first.
Secondly I find all area detail of India. And last but not the least prefixes 4 digit of mobile number in different area with providers.
Once I got this I made a database with this three combination
1) lkuArea table:- in this I keep area code, state Name, state Capital
2) lkuServiceProvider table – in this I keep provider code, provider name, provider web site
3) tblMobileCode table – in this we keep MSC code, lngAreaId, lngService Provider id.

Once I did this. Then I inserted the data according to the need of application. I have created utility to import Excel to our Mobile Track database.

Then I thought instead of showing the simple location why not we use Google map.
So I used Google map to point out position.

In this way we created this task.

You can checkout the code at http://www.mymobilelocation.tk/

More over in next couple of week I will show you how to track your mobile’s real time position.
It’s also very interesting thing.
Please give you your feedback on this.

Thanks

Windows Explorer Has Stopped Working Fix

2012-07-28T12:27:00.009-07:00

Windows Explorer Has Stopped Working Fix

Windows Explorer is an essential program of the Windows operating system. It is one of the backbones of the operating system powering not only file browsing and operations but also the taskbar and start menu.

The message “Windows Explorer has stopped working” is relatively common judging from the number of web pages and solutions that users and webmasters have posted over the years on the Internet.

The goal of this troubleshooting guide is to provide users who are experiencing the Windows Explorer error with the most common solutions and fixes.

Windows Explorer Has Stopped Working

Solution 1: File Check

This solution checks the operating system for missing and corrupt files and replaces them with the original file version to make sure only valid files are used. This helps in cases of data corruption and malicious attacks that have modified or deleted core operating system files.

1. Click Start, and then type cmd in the Start Search box.
2. In the results area, right-click cmd.exe, and then click Run as administrator. You will be prompted to type the password for an administrator account. Click Continue if you are the administrator or type the administrator password. Then, click Continue.
3. At the command prompt, type Sfc /scannow, and then press ENTER..

Solution 2: Scan Disk

The files and folders may be valid but it can still be that the hard drive has bad sectors or other problems that lead to this Windows Explorer error message. Scanning the hard drive that Windows is installed on for disk errors is another option to resolve the issue.

1. Open the Start Menu and click on the computer link.
2. Right-click the hard drive that Windows is installed on (usually c:) and select Properties from the context menu.
3. Switch to the Tools tab and select the Check Now button under Error-checking
4. Make sure that both options are selected before you press the Start button.
5. The Disk check needs to be scheduled as the disk is in use when the operating system is running. It will start the scan automatically on the next startup.

Solution 3: Updates

Make sure your system is up to date. Check for Windows updates (via Start button > all programs > Windows Update) and software updates if the software is running in the background. Make sure you update drivers for the hardware as well (especially video card)

Solution 4: Scan the system with security software

A virus or other malicious software might be the cause for the issues with Windows Explorer. Scanning the system with security applications ensures that no virus or other malicious code is running on the system that is causing the problems.

Check out this extensive listing of security applications. Recommended are for instance Malwarebytes Anti-Malware, DrWeb and Gmer. You might want to run at least one program in the categories anti-malware/spyware, anti-rootkit and anti-virus.

Solution 4: Disable Third party services and tools

Another possible cause for the Windows Explorer has stopped working error message is a third party program or service that might be conflicting with it.

To eliminate that possibility we need to disable all third party services and programs. This is best done in the System Configuration tool.

1. Click on the start button, type in msconfig in the run form and select the Msconfig tool from the search results.
2. Switch to the Startup tab first and remove all selected entries there. Please note that this can mean that a security software is disabled. You might want to keep that checked just in case. It can however be the cause for the explorer problems.
3. Switch to the Services tab and check “Hide all Microsoft services” at the bottom. This ensures that only third party services are displayed. Disable all the selected services as well and restart the computer afterwards.

Solution 6: Check For Memory Problems

This can be done in Vista and Windows 7. Click on the start button, type mem and hit enter. This will open the Windows Memory Diagnostic tool which will perform a memory scan on the next system startup.

Solution 7: Corrupt non-system files

The error message can appear if the Windows desktop or the startup directory of Windows Explorer contains corrupt files. The most common cause are multimedia files that are corrupt. It can also be that you are only experiencing the issue when opening a specific folder or drive in Windows Explorer.

Try to locate the corrupt file and move it or delete it so that it resolves the problems. If you cannot use Windows Explorer to delete or mote the files use the command line to do so.

This sevens solutions have resolved the “Windows Explorer Has Stopped Working” issue in the past. You might want to check the Event Viewer if the problem persists or fall back to a previous system restore point to resolve it.

Have you been experiencing this error message? If so, what have you done to resolve it?

Securing the Black Hat Wi-Fi Network

2012-07-28T12:03:00.000-07:00

Securing the Black Hat Wi-Fi Network

How do you provide military-grade secure wireless network connectivity to 6,000 hackers? We take a look inside the Network Operations Center at the Black Hat 2012 conference.

By Abin | July 26, 2012

LAS VEGAS. With over 6,000 attendees, the Black Hat Wi-Fi network is one of the most hostile networks on Earth. Attendees routinely test the network and attempt to exploit both the show as well as other attendees.

The job of provisioning and defending the Wi-Fi network at Black Hat falls to Aruba Networks. It's a job that Aruba has been doing at Black Hat both officially and un-officially for the last seven years. For this year at Black Hat, Aruba deployed more than 35 access points across multiple session rooms to deliver seamless connectivity.

Aruba engineer Robbie Gill explained to TechnoHelp that approximately 15 of those access points are connected in a mesh topology. In a mesh, each access point can connect to another access point in order to provide backhaul connectivity. The others can be directly connected to the main controller.

Rogue access points is one of the challenges faced by Aruba. Clogging the available spectrum, these rogue access points often turn out to be mobile handsets with Wi-Fi sharing capability turned on.

Donald Meyer, senior manager of product marketing at Aruba, explained that his company has a technology called Adaptive Radio Management (ARM) that will automatically move across different channels in order to find one that is less congested. For end users, there is no disruption as the Aruba network continuously adjusts to conditions in the air.

Aside from rogue access points, Gill faces other type of challenges as well -- including denial of service and spoofed access points with Karma.

At this year's event, Aruba is only providing WPA-PSK security, as opposed to the more robust EAP/TLS (Extensible Authentication Protocol – Transport Layer Security). With EAP/TLS each user has their own key, whereas with PSK the key is known.

As such, WPA-PSK is not as secure as the EAP/TLS option that was available in 2011 at Black Hat. Gill noted that as long as users maintain proper security best practices -- not sending data over clear text and stick to HTTPS/SSL secured sites when submitting sensitive information -- there shouldn't be much risk.

165 Hackers Arrested in China

165 Hackers Arrested in China

The gang is accused of attacks on 185 government Web sites.

By Abin | July 26, 2012

Police in China have arrested a gang of hackers accused of involvement in attacks on 185 government Web sites.

"The group made their money by selling fake qualifications certifying the recipient in fields such as medicine, financial services and architecture, with over 30,000 people suspected of having bought the dodgy certificates," writes The Register's Phil Muncaster. "The gang’s USP, and the reason it could charge up to 10,000 yuan ... per certificate, was that it could hack the relevant government site and tamper with the back-end database to ensure that the fake cert’s name and registration number appeared legitimate."

"As of July 12, police had arrested 165 people, confiscated more than 7,100 fake certificates and at least 10,000 fake seals, and are still hunting for more members of the gang," write China Daily's Xu Jingxi and Zhang Yan. "The fake certificates were sold at between 4,000 and 10,000 yuan ($626 and $1,565), police said. The profits generated surpassed 300 million yuan."

"China Daily reported the crackdown began when the city's office of personnel and examinations reported an attack on its site on Dec. 8, 2011, after finding a link had been illegally added," writes ZDNet's Jamie Yap. "This led police to seven suspects who sold fake certificates in Nanjing, Jiangsu province and Heyuan in Guangdong, and subsequently the discovery of a network of hackers, certificate forgers, advertisers, and personal data collectors scattered across at least 12 provinces in China."

Cisco Patches Videoconferencing Security Flaws

The company has fixed 10 different vulnerabilities in its TelePresence products.

By Abin | July 30, 2012

Cisco recently published four separate advisories warning of a range of vulnerabilities in its TelePresence videoconferencing products that could enable remote code execution, denial of service, or execution of abritrary commands on the underlying operating system.
"In all, Cisco alerted users to ten distinct security vulnerabilities in elements of its videoconferencing products ranging from the network switch that routes the service’s data to the endpoint hardware ... The revelations of security flaws in Cisco’s gear aren’t the first time executives have been warned about potential eavesdroppers on their conference table talks," writes Forbes' Andy Greenberg. "In January of this year, security researcher H.D. Moore revealed that Cisco competitor Polycom shipped its videoconferencing tech with an auto-answering functionality that would allow a hacker to spy through the company’s cameras at will."
"According to Cisco's advisories, the vulnerable components include the TelePresence Manager, Recording Server, Multipoint Switch and the TelePresence Immersive Endpoint System. ... Cisco has released a series of security patches to address the flaws and administrators are being advised to make sure that all of their TelePresence products are fully up-to-date," writes V3.co.uk's Shaun Nichols. "The patches are being offered by the company for free."
However, in the case of the Cisco TelePresence Recording Server, the advisory states, "There are currently no plans to resolve the malformed IP packets denial of service vulnerability, as this product is no longer being actively supported."

Windows 8 Logon Screen for Windows 7 and XP

Windows 8 developer preview was released the past week with much enthusiasm and encouragement. The Windows 8 welcome screen is clearly based on the Windows Phone 7 lock screen that has been appreciated by consumers. The Metro based user interface of the welcome screen gives it a clear look.

As of now in the developer build, you can only change the background image and the rest are not configurable, but this surely looks to change by the time the commercial release is made available.

Windows 8 Login Screen

The log in screen has also been made more touch screen friendly owing to the fact that this version supports multiple hardware platforms. In the build conference, Microsoft showcased how an user could log into his or her system by touching two unique points on a photograph. Facial recognition and other bio-metric security is planned for the main release.

Windows 8 Logon Screen for XP

You can download this pack created by a DevianArt user here. Replace the logonui.exe file in the system 32 with the new logonui.exe you downloaded. Your log in window will change to the Windows 8 style. There is also another way to change the screen manually, this involves tweaking the Windows Registry and is not advice for novice users. Follow these steps to change your log in screen manually:

1. Download this registry file to your computer

2. Go to your System32 folder. This should usually be at C:\\windows\system32
file://oobe/

3. Create a new folder named info

Requirements:

BSNL 3G data card, balance on your BSNL 3g account for making voice calls.
