HP deal wasn’t explained clearly: Autonomy CEO

September 27th, 2011

Autonomy Corp Chief Executive Officer Mike Lynch said the logic behind his company’s $10.3 billion takeover by Hewlett-Packard Co hadn’t been clearly communicated and he plans to stay in his current position for at least a couple of years.

Hewlett-Packard’s Chairman Ray Lane and new CEO Meg Whitman informed Lynch of plans to replace her predecessor Leo Apotheker “a couple of days before it became formal,” Lynch said today in an interview. HP, which ousted Apotheker this week after less than 11 months as CEO following three sales forecast cuts and strategy shifts, is prioritizing the completion of the Autonomy acquisition, he said.

“It was a shame that the rationale hadn’t been clearly communicated,” Lynch said of the takeover of the UK’s second- largest software company. “It’s not just another software acquisition.”

Pressure on Apotheker intensified on August 18, when he announced an overhaul that included the acquisition of Autonomy and a possible spinoff of the personal-computer business. He also killed off the company’s WebOS tablets and smartphones.

Apotheker was unaware that his position was being questioned until news broke on September 21, according to a person close to the situation.

Lynch’s strategy

Lynch, who founded Autonomy in 1996 and owns 8 per cent of the software maker’s shares, will report directly to Whitman, he said. Whitman, the former CEO of EBay Inc, said yesterday she planned to continue with Apotheker’s strategy to avoid alienating shareholders unsettled by changes in course under the previous tenure.

Lynch “is closely associated with the success” of Autonomy, Milan Radia, a managing director of equities research at Jefferies International Ltd, said in an interview on Bloomberg TV. “He’ll have had a meeting of minds with Leo, and suddenly Leo’s not there anymore.”

There’s a risk that Autonomy would “become an orphaned asset within HP if the strategy doesn’t come together,” Radia said.

Hewlett-Packard cares more about hardware than the software business, Hewlett-Packard’s Lane said today on CNBC.

Autonomy, based in Cambridge, England, will give Hewlett- Packard software that searches a broad range of information, known as unstructured data, including e-mails, music, video and posts on social networks such as Facebook Inc.

What happens when you don’t have a computer?

September 27th, 2011

It’s hard for my kids to imagine not having a computer. Every person in my family has one (except the almost 2-year old; she just steals her brothers’ machines). I get enough demo units and upgrade frequently enough that there are, in fact, computers to spare. There are, however, countless students and families who don’t share that luxury. Which is why, although I haven’t had much time to write this week, I wanted to end the week highlighting a couple of efforts by Microsoft and Intel to improve access.

Microsoft announced Wednesday as part of the Clinton Global Initiative Annual Meeting that it was launching “a three-year program to ensure that one million students from low-income families in the United States receive reduced-cost software and hardware and discounted broadband internet service.” The program is an extension of their Shape the Future initiative and is beginning in Seattle and Charlotte, NC.

Almost 10 million children in the US don’t have access to computers outside of school, even as schools increasingly require computer-based work at home and their wealthier peers can access a wide variety of learning resources online. Online tutoring services, even, like Grade Results, that could help at-risk students graduate are inaccessible to the very students who need them the most.

Microsoft’s program involves partnerships with a variety of OEMs and Internet Service Providers to drastically reduce the cost of Internet service and computer hardware, while Microsoft is providing OS and productivity software.

Intel, on the other hand, announced an initiative today to focus on educating health care providers in developing countries. As Mike Gann, the director of Intel’s World Ahead Healthcare group, explained to me, the first time he asked a health care worker in South Africa about ongoing training, she explained that she “delivers babies under a tree.” Obviously, opportunities for professional development and internet research on advances in midwifery and childbirth are few and far between.

Intel’s World Ahead program is devoted to improving access to technology in developing areas and works closely with the Classmate program (which is how this hit my radar). In this case, however, the World Ahead Healthcare group is looking at subsidizing ruggedized netbooks for content delivery, full-featured computers for local content creators, and, again, ways to improve Internet access. The company will also be using its Skoool learning platform to host content for health care providers.

Two different approaches and two different specific problems, but the overall issue of the “Digital Divide” is a very real one, both here in the States and worldwide. For those of us who take our tech for granted, there are literally billions of people who don’t.

Mini-quantum computer passes test

September 27th, 2011

Scientists from Delft University of Technology and the FOM Foundation have succeeded in very accurately reading out a mini-quantum computer comprising four quantum bits on a chip of diamond. It marks an important step towards a quantum computer and makes it possible to test quantum algorithms, such as teleportation, on a chip. The researchers published their results 21 September online in Nature.

A major challenge along the path to realising a quantum computer and the associated large-scale quantum hardware is the initialisation and reading out of the minuscule quantum bits. The spin rotation of both individual electrons and atomic nuclei functions as a quantum bit: left spin is a ‘0′, and right spin is a ‘1′. Atomic nuclei are highly stable quantum bits as they scarcely interact with their surroundings. However, this property also makes it difficult to read out the state of atoms. A team from Delft University of Technology under the leadership of FOM scientist Dr.ir. Ronald Hanson has now solved this problem by using a captured electron as an intermediate station in the measurement.

Reading out quantum bits
The researchers can now determine the state (spin direction) of the electron quickly and accurately. They do this by sending laser pulses of an accurately preset wavelength at the electron. The electron absorbs the light and transmits it again if it is in the ‘0′ state but does nothing if it is in the ‘1′ state.

To read out the spin direction of the atomic nuclei as well, the researchers first perform a quantum operation. The electron then gets entangled with the atomic nuclei, and the information about the atom is transferred to the electron. The researchers subsequently read out the state of the electron and from this derive the original state of the atomic nuclei.

This measurement technique is special because the measurement does not alter the state of the atomic nuclei. It is therefore an ideal way of preparing the atomic nuclei for further quantum calculations and so for use in a quantum computer. The researchers demonstrated their technique on a mini-quantum computer comprising four quantum bits on a diamond chip.

Diamond future
The discovery that the fundamental natural laws of quantum mechanics make it possible to perform ultrafast calculations and transmit information completely securely, has elicited a worldwide race to construct the necessary ‘quantum hardware’. For the past few years diamond has been the favourite material as quantum states are scarcely disrupted in this. This new read-out technique for quantum bits in diamond provides the researchers with many possibilities. For example, they want to test interesting phenomena such as teleportation and multiparticle entanglement in the laboratory. The read-out also makes it possible to implement the correction of elementary quantum errors, an essential aspect of a large-scale quantum computer.

The research was supported by a Marie Curie Intra European Fellowship of the Seventh European Community Framework Programme, FOM, the European Commission (SOLID) and the Research Corporation for Science Advancement (RCSA).

How to Recover a Lost Phone, Tablet, or Laptop

September 27th, 2011

CoburnThe bad news: At some point, your cell phone is likely to go missing. Whether it falls out of your pocket in a cab, or you leave it unattended in a public place for a few seconds only to have it swiped by someone with sticky fingers and low moral fiber, your phone is vulnerable. In fact, according to a report from security software company Symantec, 36 percent of U.S. consumers have had a cell phone disappear on them.

If that phone is a smartphone–or if the missing item is another valuable mobile device such as a laptop or a tablet–thieves will be even more motivated to do their dirty work. And misplacing your gear or having it stolen is more than just a hassle: Given the amount of information that people store on their devices, losing a gadget may very well mean not only losing your files, contacts, and photos, but also seeing your identity stolen.

What can you do? Start by following these simple steps before your favorite tech goodies go MIA. Although we can’t guarantee that you’ll get your missing phone, laptop, or tablet back, we can at least help you ensure that no unauthorized person starts peeking at your most personal details, and we can help you increase the odds that your gadget will return to you.
Preventive Protection

Use a password: The first step in securing your laptop, phone, or other mobile device is to put a password on it. Needing to enter a password whenever you use your phone may seem inconvenient, but you’ll appreciate having taken the precaution should the device fall into the wrong hands.

On iOS, you can assign a four-digit PIN to keep your iPad or iPhone from being unlocked easily. If you own an Android phone, you can choose either a PIN or a pattern; with a pattern, you unlock your device by drawing a simple shape on the screen. For both Android and iOS, these security options reside under the ‘Settings’ menu. For most Android devices, the option to add a PIN or pattern appears under ‘Location and Security’. On iOS you’ll find the option to set a PIN under ‘General’, then ‘Passcode Lock’.

Remember not to choose an excessively simple PIN like 0000 or 1234. You don’t want to make it unduly easy for anyone other than yourself to access your assorted devices.

In addition, always lock your laptop’s screen when you step away for any period of time, to keep prying eyes from peeping at your work. In Windows, hold down the Windows key and press the L key; that will take you to the login screen.

In Mac OS X, open Keychain Access in your Utilities folder (or do a Spotlight search for it), and within the Keychain Access menu, select Preferences. From there, check the box labeled Show keychain access in the menu bar. A lock icon will appear in the menu bar; that icon will allow you to lock your password keychains, as well as your screen.

Use security software on your smartphone: Even though PINs, patterns, and passwords are a good first line of defense, you’ll need much more to keep your data safe. In fact, one of the first things you should do when you purchase a new phone is to install a mobile security suite.

On Android, apps such as Lookout Mobile Security, Norton Mobile Security, Seekdroid, and Webroot Mobile Security let you remotely locate your absent device, lock it, or wipe all data from it. Some of these apps also in­­clude antimalware and phishing safeguards, so you’ll be protected even in your day-to-day activities. Seekdroid costs $1, while the rest of the listed mobile security suites are free (you will have to pay extra to unlock all of their features, however).

Apps for iOS are more limited. We recommend that you install the Find My iPhone app on all of your iPads, iPhones, and iPod Touches. After installing the app, you can use your Apple ID to sign in to Me.com, which will open to a map showing your iOS device’s approximate location, as well as options for displaying a message on the lost hardware, remotely locking it, or remotely wiping it. Find My iPhone does require a little setup, but operation is straightforward once you have it working.

The only drawback to Find My iPhone is that it’s easy to disable, whereas several of the Android security suites we’ve mentioned will either request a password or hide the app. We’re hoping that you followed our earlier advice and set up a PIN on your device to prevent people from getting into it and then uninstalling the security app.

Track your laptop: You can hunt down a lost laptop in much the same way that you track a missing smartphone. Consider investing in LoJack for Laptops, a subscription service that makes it easier for both you and law enforcement to find your laptop. The service permits you to track the notebook’s location (some plans track only IP addresses, while others track by using GPS), lock it so that nobody can access the data, remotely wipe the hard drive, and perform other tasks. LoJack requires a piece of software that you install on your computer; versions are available for Windows and Mac. Plans start at $40 per year.

If you prefer tracking your laptop yourself, try out Prey, which installs a small piece of software on your computer that lets you track the system’s location via an online control panel. You can also capture screenshots of your laptop if it goes missing (to gather information about a thief), take a photo using the built-in webcam, sound an alarm (useful if you misplace your laptop nearby), remotely lock the computer, and more. The Prey software runs on Windows, Mac OS X, Linux, and Android; installation is fairly straightforward.

The free version of Prey allows you to monitor up to three devices (computers or Android-based phones), and the various “Pro” account options range in price from $5 for a personal account to $400 for a large business.

At this writing, Apple was working on Find My Mac, which is similar to Find My iPhone but for Apple laptops. Find My Mac may be available by the time you read this.

A word of caution: Privacy concerns about device-tracking products have begun to emerge. Shortly before we went to press, a judge ruled that a woman in Ohio could sue Absolute Software, makers of LoJack for Laptops, for allegedly infringing on her privacy after she had unknowingly purchased a stolen laptop. So if you decide to use a device-tracking product on your gear, be sure to use it responsibly.

Lock your laptop: A physical lock isn’t foolproof, but it will help prevent someone from swiping your machine off your desk. Companies such as Kensington and Targus sell assorted products that attach to or link through the lock port on most laptops. One from Targus even has an alarm that sounds when someone picks up your laptop.

First Ever Computer Forensics Firm Established in Ghana

September 27th, 2011

Ghanaian expatriate, Albert Antwi-Boasiako has established the first ever computer forensics firm with a dedicated e-crime laboratory in the country to assist corporate bodies, the law enforcement, government institutions and stakeholders to fight the emergence of cyber related criminal activities in the sub-region.

The company, e-Crime Bureau has been established to offer a wide range of services including computer and mobile phone forensics services, digital forensics expert witness services, data security & cryptographic services, e-fraud investigations & countermeasures, incident response and cyber intelligence analytics.

In addition, the company is developing strategic
partnerships with research partners, both locally and internationally to carry out research into the emergence of online criminal behaviour which continue to dent the credibility of countries in the sub-region.

“The fact that many international reports continue to rank Ghana and Nigeria among the top ybercrime offending nations is a worrying development for our countries especially at the time when our overnments are actively promoting ICT literacy at all levels; our enthusiasm to accelerate development through ICT should be complemented with ethical behaviour online as a nation”, the founder advised.

“Our resolve in establishing the first ever computer forensics lab in Ghana is to assist businesses and government institutions across the sub-region to secure their ICT infrastructure and to provide investigation support in high tech crime cases,” Mr Antwi-Boasiako concluded.

Apart from services in ICT infrastructure security and computer forensics being provided by the company, e-Crime Bureau will also develop training programmes in cyber security, incident response, internet investigations and computer forensics among others.

The company has also developed partnerships with global cyber security and computer forensics solution providers to help provide customized technology support through the deployment of appropriate software and hardware solutions.
The e-Crime Bureau Team is made of both local and international consultants with varied specializations in the field of cyber security and computer forensics.

One of our strategic goals as a company is to expand our operational base across Africa and to
facilitate greater working cooperation with stakeholders including businesses, academic institutions, law enforcement bodies and
government departments. The company has begun discussions with local representatives to open e-Crime Bureau branches in other Africa countries.

Backing up and Restoring Windows Drivers

September 27th, 2011

The hardware driver support in Windows 7 is just fantastic, especially with consumer hardware with more and more companies submitting their drivers for official certification from Microsoft than ever before. This not only means driver support on the Windows 7 installation DVD, but also through Windows Update. You can still find computers however for which the driver support is lacking, my own laptop, the Dell M6600 is a great example of this where the drivers for the graphics (both internal Intel and nVidia), USB3, biometrics, touch-panel, Wi-Fi, Ethernet and SD Card reader are not installed automatically by Windows, nor by Windows Update. Each one requires a driver download from the Dell website (which is annoying!)

So how do you back up the drivers in your Windows installation and how can you use these? In all versions of Windows the drivers are stored in the C:\Windows\System32 folder in the sub-folders Drivers, DriverStore and if your installation has one, DRVSTORE. These folders contain all the hardware drivers for your operating system. In the folder location, C represents the drive on which you have Windows installed, this may be a different letter on your system.

You can simply copy these folders out to seperate storage (DO NOT MOVE THEM) such as an external USB drive or Pen Drive. When time comes to reinstall the drivers you can copy the folders back.

Now there are a couple of ways to reinstall the drivers. The easiest way is to simply restart the PC when the driver folders have been copied back to see if Windows automatically detects drivers for uninstalled hardware. This is possible, but won’t be the case for all your hardware.

To install drivers for the missing hardware you need to open the Device Manager. You can do this by typing Device Manager into the search box in the Start Menu. You will see all your uninstalled drivers highlighted with a small yellow warning triangle icon. You need to Right-Click on each one and select Update Driver. Because the correct drivers are already in the drivers folders on your computer, telling Windows to find the drivers automatically should always install the correct one. You may however, in some cases, have to tell the Device Manager which folder to look for. You can either point it directly to one of the two drivers folders, or just at the System32 folder; making sure you tick the box “include subfolders”.

There is an important caveat with this. The drivers for 64 bit (x64) and 32 bit (x86) versions of Windows are usually different. This means that if you copy x86 drivers into an x64 copy of Windows; or vice-versa, they will not install. Windows will recognise them as being incorrect. You cannot use this method therefore when migrating your system from the 32-bit version of Windows to the 64-bit version when, for example, adding more memory to your PC.

You CAN use this method to migrate drivers between Windows Vista and Windows 7 (and back again) as both operating system share the same driver model, but again not between x86 and x64 builds. You CAN’T use this to migrate Windows XP drivers to Vista or Windows 7 however as Windows XP uses an older driver model and the hardware drivers for XP are not compatible with the newer versions of Windows.

How Windows 8 could affect the future of Microsoft Hyper-V

September 27th, 2011

Regular updates on the Building Windows 8 blog paint an increasingly detailed picture of what we can expect from Microsoft’s next desktop and server operating system.

Perhaps no single entry so far has been as provocative or interesting as Steven Sinofsky’s Sept. 7 post entitled “Bringing Hyper-V to ‘Windows 8,’” which states that a revised version of Hyper-V — based on the one included with Windows Server 2008 (and improved, somewhat, with the subsequent R2 server release) — will be included in both desktop and server versions for this OS.

Let’s explore what this new Hyper-V can do, why its inclusion in Windows 8 desktop versions matters and how it
