HP Releases Firmware Update To Prevent Printer Hacking

December 27th, 2011

A few weeks ago, a group of researchers announced that they were able to exploit a security hole in some older Hewlett-Packard printers that allowed them to take the printers over. In one demonstration, they were able to heat up paper to the point where it started smoking, and in another were able to send social security numbers from documents to other systems.

The problem was that the printers did not check to verify to source of any firmware updates – the software that controls the actual physical hardware in the computer. So the researchers were able to update the printers with fake firmware that contained software that let them control the printers and take advantage of their network access and other systems.

After this report was announced, HP released a statement stating that no systems had been reported compromised by this potential attack. Moreover, the company claimed that this would not impact any printers produced after 2009. Printers produced after that point did check for a digital signature.

Well, now people with older printers can rest easy, as well. HP has released a firmware update that should fix the security exploit, and is actively working with its customers to make sure that the updates get installed.

What’s not clear is whether the firmware update could fix a printer whose security has already been compromised, but to date I haven’t seen any reports that this exploit has been employed against anybody, so that’s probably a non-issue.

Despite the quick fix, one thing that this does highlight is the increasing vulnerability of embedded systems. Especially as more and more of the things we use every day use networks, even things we wouldn’t think of in a computing sense.

US$25 Raspberry Pi personal computer nears launch date

December 27th, 2011

Budding computer hackers/scientists are about to get a welcome gift, albeit a bit late for Christmas 2011. The non-profit Raspberry Pi Foundation (RPF) is nearing the release date of its surprisingly powerful and remarkably affordable Raspberry Pi line of bare-bones machines that have been developed in an effort to broaden kids’ access to computers in the UK and abroad. How affordable? The figure above was no typo. Read on to learn just what US$25 will get you when these nifty, fully-assembled, credit-card sized computers go on sale next month (sorry, case, monitor, keyboard and mouse not included … we did say bare bones).

Early models of the Pi will be offered in two versions. The first, Model A (US$25), will sport 128M of RAM but no Ethernet port. Presumably, most of these will end up in educational use. The second, Model B (US$35), will have a larger production run and offer 256M of RAM along with 10/100MBit networking capability. Both are powered by 700MHz ARM11 CPUs and include hardware support for OpenGL ES 2.0 and Blu-Ray caliber (1080p30 H.264) playback.

Video, HDMI and audio outputs, a USB port (the Model B has two), a Flash memory card reader and several I/O (input/output) pins all come mounted on a 3.34 inch (85.6mm) by 2.08 inch (53.98mm) board around .67 inch (17mm) high. The whole unit weighs about 1.6 ounces (45g) and runs on 5 volts supplied by a micro USB socket rather than an onboard power supply (PSU) – the A draws 2.5 watts, the B, 3.5 watts.

Once the system is configured with user-supplied peripherals, Pi will initially drive ArchLinux, Debian and Fedora ARM GNU/Linux distributions – RPF has plans to add others later on. When it’s up and running, the operating system presents in typical Linux format with command-line and desktop interfaces. Once channeled through the ARM architecture, document editors, web browsers and numerous other packages will perform as they would on a typical PC.

The Raspberry Pi is not much bigger than a credit card

Unfortunately, Pi won’t run Wine compatibility software, so Windows and other X86 apps aren’t supported. Obviously, to keep the price so low, a number of desirable features had to be scaled down or eliminated entirely. But then, that also serves as incentive for creative hacking, which is what the Raspberry Pi is all about.

A major force behind the whole project has been Eben Upton, current director of RPF. Back in 2006, while in the admissions department of Cambridge University, he noticed a downward trend in the skill-sets of A Level Computer Science applicants. Along with several colleagues (now also RPF trustees), Upton identified several reasons for this declining computer savvy among students. Gone were the Amigas, Commodore 64s and other machines of that ilk upon which the previous generation learned to program, replaced with home PCs and game consoles. Overall, curriculum emphasis had begun to switch from programming to website design and the fading dot-com boom didn’t help matters much, either.

Upton eventually left Cambridge and became a SoC (system-on-a-chip) architect at US Fortune 500 semiconductor giant Broadcom. In his spare time, he began designing prototype machines with the aim of restoring computer literacy via affordable access to the hardware. By 2008, multimedia capable CPUs, originally designed for mobile devices, became inexpensive enough that Upton’s dream had a real promise of coming to fruition.

Over the next three years, Upton and his Pi team scoured the world in a quest for low-cost quality components that would meet their design and price-point goals. Now, finally, the results of all their hard work are about to pay off. Evidently, good things still do come in small packages.

“I’d say that I very much hope that 2012 will be the year that Raspberry Pi, and other cheap, open devices like it, begin to change the way that people, and in particular children, interact with technology,” Upton told Gizmag. “The future of our economy depends on our producing a new generation who have the skills and understanding to create new technologies rather than merely using them. Hopefully initiatives like ours can make a small contribution to this goal.”

How can I restore iPhone to factory settings with iTunes?

December 27th, 2011

If you need to restore the iPhone to its original state the process requires iTunes. This can be useful for troubleshooting to see if a problem is hardware or software related. The process can also reset an iPhone for resale, wiping all personal data from the device.

Should you suspect a hardware issue with your iOS device, Apple will normally recommend a complete restore to see if this clears up the problem. You can save time when you go to the Apple store by trying a complete restore first. Restoring will update your iPhone firmware to the latest version.

If your iPhone is booting to a black screen you need to follow additional steps before restoring your iPhone. See these additional instructions by clicking here.

1. Connect your iPhone to the computer and open iTunes.
2. Make sure your iPhone is selected from the left menu in iTunes.
3. Click the Restore button in the center of the iTunes Summary tab.
4. You can choose to Back Up the contents of your iPhone to the computer.
5. iTunes will ask if you’re ready to Restore the iPhone, this will wipe all of your data and settings from the device. Click Restore.
6. iTunes will download, prepare and restore the software on your iPhone. Do not unplug the iPhone from the computer during this process!
7. When finished, iTunes will ask if you want to restore from backup. Choose “Set up as a new iPhone” to start fresh with factory settings.
8. Enter a name for your iPhone and the process is complete.

Computer work without distractions

December 27th, 2011

With the fog of Facebook, YouTube and emails that seem to regularly pop up on computer screens, it’s a wonder anyone ever gets any actual work done these days.

Try as one might to concentrate, the internet generally means that distractions – social networks, news updates, or emails from friends – are but a click away for most workers.

The good news for procrastinators and the easily distracted is that there are tools out there that will block distractions such as Facebook and YouTube and even stop email alerts.

The bad news is that you’ll still need loads of willpower to make such systems really work.

Evolution can be thanked for the fact that humans are so easily distracted.

If something moves nearby, our attention is automatically directed towards it. Psychologists call this an orientation reaction.

Once, it was necessary for survival. After all, the flash of movement could easily be a hungry sabretooth tiger.

The instinct remains, even though offices are rarely the site of life-or-death situations. That means humans are routinely overloaded with input in today’s fast-paced workplace, says Andreas Zimber of the SRH University Heidelberg in Germany.

It doesn’t help that the ever-present emails seem to demand immediate answers.

“Because the medium is so fast, everyone expects that answers will come quickly,” says Zimber, a professor of business psychology. That leads to two problems.

First, says Zimber, people lack the focus to concentrate on important tasks. That focus is needed to work efficiently, and with less effort.

“Based on surveys, we know that interruptions at work are one of the main sources of disruption.”

The distractions also cater to procrastinators, providing a welcome excuse to shove unpleasant tasks further down on the to-do list.

“That’s when the hedonistic principle kicks in: I’ll pick the more pleasant task,” notes Zimber.

So what’s to be done? Zimber advises a system of compartmentalisation. If possible, lay down fixed office and visiting hours.

When it comes time to do important work, shut your email inbox and make sure everyone knows you’re entering a period of enforced isolation.

That could shut down the problem of three or four avenues of information coming in simultaneously. “Colleagues will usually understand,” says Zimber.

Some word processing programs even help enforce this practice.

For example, Focus Writer covers up all open windows and only shows the basic text upon which you’re working.

Toolbars and other extras only appear when you pull the mouse to the edge of the screen.

For those who need extra motivation, the programme allows them to set a writing goal – a set amount of time or a specific number of words. The free program runs on Windows, Max OS X and Linux.

But the distractions are always out there, especially if you just have to quickly check something online … and then find yourself stuck on Facebook. Two browser extensions promise to stop aimless surfing.

Stay Focused allows Chrome users to set a specific amount of time they are allowed to stay online. Users set their own list of no-go websites.

Many choose to block time-killers, such as video portals, games or social networks, while leaving accessible useful sites such as dictionaries or Wikipedia.

Leech Block performs a similar function for Firefox and Explorer.

Users get an icon reminding them a site is forbidden if they try to wander into no-go territory.

The free URL blocker works independently of the browser.

Still, none of these systems erases the need for discipline.

Committed time wasters can also just switch to non-blocked browsers or restart their computer to fool the efficiency programmes.

Procrastinators need to be honest about listing the time-killer websites to be blocked, ideally just as they’re experiencing some regret about recent dalliances.

Recognising the problem is the first step towards improvement.

That’s why programs such as RescueTime measure how much time is used for different activities.

The free version of the software, which runs on Windows and Mac, documents which programs and websites are visited on a computer.

A fee-based version goes further, listing how much time is spent on individual documents.

Both versions can provide eye-openers. As an added feature, the program allows a Focus Time function, which blocks certain activities for set periods.

Freelancers who work at home can do themselves a favour by having separate computers for work and leisure, no real problem with today’s hardware prices.

That’s another way to take control of the information flood.

Braben’s $25 Raspberry Pi to launch next month

December 27th, 2011

Braben’s $25 Raspberry Pi mini-computer project for schoolchildren gets a January release date; with two different models to choose from.

You might remember a brief blip about video game veteran David Braben and his low-cost mini-computer project named the Raspberry Pi a while back. Well, it seems like he’s finally finished developing the computer and may be ready to launch in January.

The new version is a little bigger than the USB sized protype but is still roughly the same price, and price was arguably the main point of the project. Braben wanted to make it easy to distribute the starter computers among high school students in order to develop interest in programming at an early age.

The Raspberry Pi has now been split into two versions: One priced at $25 and one at $35. The 25$, Quake 3 Arena running device is packed with the protypes same 700MHZ ARM 11 processor, runs Linux and has the same USB and HDMI ports. The latest version has128MB of RAM, uses an SD card and has an audio and RCA video jack. The $35 model gets you the same specs, plus 256MB of RAM and an Ethernet port.

Raspberry pi beta board

The boards are currently being fine-tuned—undergoing electrical, hardware and software testing. The team is shooting for January, but it should be noted that this was moved from the original hope for the end of 2011. Aside from the general January release, there is also an auction for a select few to receive a device this month.

Braben stated in an earlier demonstration of the Raspeberry Pi prototype that he wished to improve on the way high schools taught computer classes, which mainly focused on office skills. He wanted school goers to be enthusiastic about creating the products they typically consume. The video below shows off the device running a Star Trek Demo as well as some computer graphics in 1080p.

Tablet market to remain small till better internet services: Lenovo

December 27th, 2011

Chinese laptop computer maker- Lenovo is planning to expand its branded retail outlets in India from around 750 now to 1000 by March, said the Indian arm’s managing director. The company may even double that number in the next year or two, because “it is a booming market, with regions that are still un-penetrated,” said Amar Babu.

Yet, the company will not compete on pricing with its operators and use existing distribution agreements to reach its retail stores rather than setting something on its own, he said. “The Indian region is so large, that the objective of the retail store is purely for brand presence in Tier III and Tier IV cities and service; not as much for first point of retail.”

Lenovo acquired its computer manufacturing business from US-major IBM in 2005. Thereafter the brand took a beating, although the IBM Thinkpad brand, that Lenovo has retained, was fairly entrenched. The company has recovered since then.

Lenovo earlier this year launched two tablet devices in the Indian market. Babu said one is designed to address the enterprise need, and although it is a little heavier it can better handle e-mail, documents, and presentations. For such users the company is also planning to launch a computer with a swivel touch screen. The other tablet is a consumer device, that despite the hype is less in demand for the moment, he said.

“Tablet sales are largely happening in the metro cities, and the models being sold are at the Rs 40,000 price point, rather than the cheaper ones; because the buyer profile is such.”

The global uptake of Apple’s iPad and similar tablet devices like the Samsung Galaxy Tab has also spread virally into the Indian media. If advertising is anything to go by, tablet devices have inundated the market at prices starting at Rs 12,999 for a Reliance Communications’ branded one.

Babu said India is still some time away from becoming a nation of ingrained tablet users. “This is only an additional screen for people using computing on the move. At home most still prefer desktop computers.” Besides, the chief mode of sharing media remains CD drives and USB storage devices in India until wireless networks and Internet service providers can offer seamless high speed data services across the country. “The preferred first computer device remains the desktop or at best has moved to the laptop,” Babu said.

Babu said, over the medium term, read two-to-five years, the company hopes to ramp up India revenue to 10% of its global revenue. At present, Lenovo India contributes around 3% to the global revenue. “The management will continue investing in India and we are very upbeat about the future growth potential of India’s PC market” said Babu.

Yet, nearly 60% of the India revenue even at that stage is likely to be from laptops sold to enterprises, he said. Of the remaining 30% would be from desktops and the only 10% from tablets and other devices.
