Mobile Phones vs. Supercomputers of the Past
The recently published Top 500 list of the world's fastest supercomputers is based on the Linpack benchmark developed decades ago by Jack Dongarra. This same test has been ported to Android mobile phones, which means that we can compare the performance of our phones against that of the supercomputers of the past. For example, a tweaked Motorola Droid can hit 52 Mflop/s, which is more than 15 times faster than the CPUs used in the 1979 Cray-1." But even today's most powerful cellphones don't come with an integrated bench.Related Posts
Facebook in SIM Card
How about Facebook comes embedded inside a SIM card you buy from your nearby store. Yeah its true...a Dutch digital security company Gemalto has made it possible and has announced Facebook for SIM card at the annual world congress in Barcelona. The company has achieved this by shrinking the facebook into such a small size that it can be stored in SIM. Therefore, enabling people to enjoy the Facebook on their GSM networks without a data plan.In doing so, Gemalto is offering Facebook to millions of mobile phone users regardless of their handset type. The app uses Class 2 SMS to ensure compatibility with the most basic handsets and networks. Class 2 SMS messages are delivered direct to the SIM without the user being involved, and then the application running on the SIM can tell the handset to alert the user. Gemalto did not reveal any release details, but emerging markets where data plans are ridiculously expensive, or simply not available, is likely the target audience.
Microsoft To Issue Emergency Fix For Windows .LNK Flaw
Microsoft will issue an out-of-band patch on Monday for a critical vulnerability in all of the current versions of Windows. The company didn't identify which flaw it will be patching, but the description of the vulnerability is a close match to the LNK flaw that attackers have been exploiting for several weeks now, most notably with the Stuxnet malware. The advance notification from Microsoft on Friday said that the company is patching a critical vulnerability that is being actively exploited in the wild and affects all supported Windows platforms. The LNK flaw in the Windows shell was first identified earlier this month when researchers discovered the Stuxnet worm spreading from infected USB drives to PCs. Stuxnet has turned out to be a rather interesting piece of malware as it not only uses the LNK zero day vulnerability to spread, but it had components that were signed using a legitimate digital certificate belonging to Realtek, a Taiwanese hardware manufacturer.

How to Convert Microsoft WMA and Rhapsody WMA to iPod
People all around the world have a preference on iPod, and today I found the reasons: In the official company FAQ, Apple says that: iPod is designed to provide the best-quality sound. iPod has a powerful 60 mW amplifier so it can deliver audio as loud as you want. It also has a 20 Hz to 20 kHz frequency response, which means you can hear distortion-free music at the lowest or highest pitches. Besides, it can skip the protection. iPod has a memory cache. It is made up of solid-state memory, that means it has no mechanical or moving parts, hence it is not affected by movement of the device. iPod skip protection works by preloading up to 25 minutes of music to the cache at a time. iPod plays music from the memory cache instead of the hard drive, so even rigorous activities won't cause music to skip. You can also remove the "gaps" between songs on the iPod. What formats does iPod support ? '''AAC''' (M4A, M4B, and M4P up to 320 Kbps) ...
EAV versus Row modeling
Following are main features/downsides EAV has over classic row modeling technique. A row-modeled table is homogeneous. I t will always carry same type of data in contrast to EAV modeled table where this cannot be an issue. The data type of the value column/s in a row-modeled table is pre-determined by the nature of the facts it records. In contrast, in an EAV table, the conceptual data type of a value in a particular row depends on the attribute in that row. A Row modeling technique data increase only in one direction i.e. from Upside-down whereas in EAV data model data increase in both directions i.e. from upside down as well as from left-right.
