Mac OS X 10.6 incompatibility list

August 31, 2009 Leave a comment

“Apple’s Mac OS X 10.6 Snow Leopard operating system was made available as promised on August 28.

After upgrading to Mac OS X Snow Leopard, Mac users may want to install their most used programs on the new Snow Leopard. However, the new operating system doesn’t really bring by default compatibility for large number of software. So Apple has listed some of them ‘incompatible’ software that won’t work with Snow Leopard.

Following is a list of “Incompatible Software” that gets moved to incompatible folder by default after installation:

  • Parallels Desktop, v2.5 and earlier
  • McAfee VirusScan, v8.6
  • Norton AntiVirus v11.0
  • Internet Cleanup 5 v5.0.4
  • Application Enhancer v2.0.1 and earlier
  • Unsanity
  • AT&T Laptop Connect Card v 1.0.4, 1.0.5, 1.10.0
  • launch2net v2.13.0
  • iWOW plug-in for iTunes v2.0
  • Missing Sync for Palm Sony CLIE Driver v6.0.4
  • TonePort UX8 Driver v4.1.0
  • ioHD Driver v6.0.3
  • Silicon Image SiI3132 Drivers v1.5.16.0″


Apple claims exploding iPhones not product fault

“Apple’s iPhone may be the darling of the mobile-phone industry right now, but some users in France aren’t singing its praises, claiming that the device explodes or cracks without warning.

However, after conducting an internal investigation into the cause of the broken touch-screen glass, Apple denies that there is an underlying iPhone flaw. In fact, Apple said that in all cases it investigated, some kind of force was applied to the iPhone, causing the glass to break, according to a BBC report Friday.”


The tree that can triple crop yields!

August 31, 2009 Leave a comment

In Malawi, Africa, maize yields were observed to have increased up to 280 percent in the zone under the Acacia tree canopy compared with the zone outside the tree canopy.

What makes this particular acacia tree so ideal is “reverse leaf phenology.” This quality drives the tree to go dormant and shed its nitrogen-rich leaves during the early rainy season—when seeds are being planted and need the nitrogen—and then to re-grow its leaves when the dry season begins and crops are dormant.

This makes it highly compatible with food crops because it does not compete with them for light—only the bare branches of the tree’s canopy spread overhead while crops grow to maturity. Their leaves and pods provide a crucial source of fodder in the dry season for livestock when other plants have dried up.”


A spacecraft that may save the Earth

“Heroic missions to stop life on Earth from being wiped out by an asteroid have become a favourite theme for Hollywood disaster films.

Now, a team of British engineers have designed a real-life spacecraft to save the world from destruction.
Their invention, called a “gravity tractor”, would be deployed when an orbiting rock is detected on a collision course with Earth.

The spacecraft would intercept the asteroid and position itself to fly alongside it, just 160ft from its surface.”


Vicious cycle of global warming – methane oozes into atmosphere

“Pure methane, gas bubbling up from underwater vents, escaping into northern skies, adds to the global-warming gases accumulating in the atmosphere.

And pure methane escaping in the massive amounts known to be locked in the Arctic permafrost and seabed would spell a climate catastrophe.”


Ghrelin – the timekeeper of hunger!

August 31, 2009 Leave a comment

“Researchers at Columbia and Rockefeller Universities have identified cells in the stomach that regulate the release of a hormone associated with appetite.

The group is the first to show that these cells, which release a hormone called ghrelin, are controlled by a circadian clock that is set by mealtime patterns.

The finding, published in Proceedings of the National Academy of Sciences, has implications for the treatment of obesity and is a landmark in the decades-long search for the timekeepers of hunger.”


Skype trojan can record voice calls

“Security giant Symantec claims to have found the public release of source code for a Trojan that targets Skype users.

Trojan.Peskyspy is spyware which records a voice call and stores it as an MP3 file for later transmission.

An infected machine will use the software that handles audio processing within a computer and save the call data as an MP3. The file is then sent over the internet to a predefined server where the attacker can listen to the recorded conversations.”


Dell, HP tries to rescue Microsoft from ‘Word War’

“Two of Microsoft’s largest customers, Dell and Hewlett-Packard, joined Microsoft in calling for the overturning of an injunction blocking the sale of Microsoft Word.

In an amicus curiae brief filed on Aug. 24, Dell asked the judge overseeing the Eastern District Court of Texas to reconsider its order blocking sales of Word, part of the original ruling in favor of Canadian software developer i4i. In the worst case, the brief argued, the injunction should be delayed by 120 days.”


Apple defies IEC, IEEE specs – tries to redefine HDD space units

August 30, 2009 2 comments

“With the release of Mac OS X 10.6 Snow Leopard, Apple has updated a support document describing how their new operating system reports capacities of hard drives and other media.

It has sided with hard drive makers, who for years have advertised capacities as ‘1 GB = 1,000,000,000 bytes’ instead of the traditional computer science definition, and in so doing has kicked the debate between marketing and computer science into high gear.

Binary prefixes for binary units (e.g. GiB for ‘gibibyte’) have been promoted by the International Electrotechnical Commission and endorsed by IEEE and other standards organizations, but to date there’s been limited acceptance (though manufacturers have wholeheartedly accepted the ‘new’ definitions for GB and TB).

Is Apple’s move the first major step in forcing computer science to adopt the more awkward binary prefixes, breaking decades of accepted (if technically inaccurate) usage of SI prefixes?”


A new look at electrical prodding of the brain

August 30, 2009 Leave a comment

“For more than a century, scientists have been using electrical stimulation to explore and treat the human brain. The technique has helped identify regions responsible for specific neural functions — for instance, the motor cortex and pleasure center — and has been used to treat a variety of conditions from Parkinson’s disease to depression. Yet no one has been able to see what actually happens at the cellular level when the brain is electrically prodded.

Now, with the aid of optical imaging technology, researchers in the lab of Harvard Medical School (HMS) neurobiology professor Clay Reid have taken the first look at this process. They found that the neural response to electrical currents isn’t localized, as some had previously thought. That is, not all neurons immediately surrounding an electrode fire when a charge is delivered. Rather, a scattered and widely distributed set of neurons switch on. These findings, which will appear in tomorrow’s edition of the journal Neuron, may end a longstanding debate about how neurons react to electrical stimulation.”
