Finger Prints and their identification are extremely useful in a lot of fields these days. The most common use of this technology is to identify criminals and is widely used by the police and other investigation agencies.
The methodology or concept behind this is extremely simple. The fingerprints of the criminal or the person concerned are matched with the available sample and identified. Lately, this technology is being widely used in the field of securities.
The next revolution with respect to fingerprints is the card less payment system. This new technology has been announced by Hitachi and is known as the finger vein money. This technology will allow users to make their payments with just the tip of their finger.
The user or the customer has to register its vein data with the service providers. Whenever you present your finger tip to make a payment, it will be scanned via infrared LED’s and matched with the sample present. The sample if matched with the one present with provider will lead to the payable sum being deducted from your account.
Before releasing the technology to the market, the company has decided to test it for three months. Employees of Hitachi will test the system in their company’s own cafeteria.
Latest Technology Development Identifies Languages With Lip Movements
Recently, a new technology has been developed by a group of researchers in East Anglia University. This latest technology is able to read lip movements to accurately recognize the languages being spoken by a person. Including English, there are some other common languages like German, French, Mandarin, Russian, Italian etc. Therefore, this technology is suitable to use with no limitation across different regions.
The development of this technology is related to modeling of 23 personnel who are bilingual or trilingual. This helps to identify multiple languages more easily without any misses. Furthermore, it shows that each language has its own uniqueness, which could be recognized with combination of lip-jaw movement and mouse shaping.
This new technology could be introduced along with the technology of eye flavor facial acknowledgment which was developed for digital signage system. It will help all of the advertisers to understand responses of consumers more effectively. Also he/she could judge that whether a particular customized ad has been meeting the needs of consumers successfully or not.
Windows 7 Does Not Support System With Display Resolution Lower Than 600 Pixels
If you are going to buy a notebook or PC, then you must consider the display resolution of the system. Recently, Microsoft has released the post that Windows 7 and Windows Vista rejects display resolution lower than 600 pixels. So if you want to install windows 7 or Vista Operating System on your computer, then ensure that display resolution is higher than 600 pixels.
Technically, windows 7 operating system refuses all the changes that you made in DPI (Dots per Inch). Therefore, you need to take care of the resolution of your system before installing windows 7 or Vista operating system. The ideal screen resolution must be higher than 600 pixels vertically in order to run windows 7 on your computer properly.
Usually when you alter the settings of DPI from “Control Panel’>> Personalization>> Adjust font Size” on Windows Vista, or “Control Panel>>Display” on Windows 7, you might have noticed that required change does not get implemented correctly. The reason is that if the display resolution of your system is lower than 600 pixels, then it will not implement the changes correctly.
In order to avoid these kinds of disturbance and interruption, it is recommended for the users to buy the device, which has display a resolution of more than 600 pixels vertically.

There is always a tough competition especially in the computing world. So when you hear of a new launch, it is not really exciting news! At the same time, you can’t avoid viewing any of this latest improvement from Super talent Technology. You may wonder what Super Talent Technology is? It is a player in the Flash storage mode and DRAM modules ands has earlier had a USB 3.0RAID DRIVE in the market.
It is interesting right now that this quick device has been made faster with a firmware update, to add a bit to the tough competition out in the market. Even if the USB drives are not so common and are updated, it is rather a unique feature. It looks like they have utilized it to the maximum, using the 2nd generation USB 3.0 technology host controllers making it possible for the RAID DRIVE to transfer date at surprisingly fast functioning speeds of 370 Mb/sec.
The raise in the speed can be above 55 Mb/sec. A number of tests were done with the help of the latest Fresco Logic FL1009B and as usual all the USB 3.0 drives are reverse-friendly with USB 2.0 ports at USB 2.0speeds. The technology firmware has been patented under US patent #7457897. Super Talent has a variety of USB 3.0 flash ranges from the economical Express DUOTM to the RAID DRIVE, the quickest of the group.
Of course, it may take a while before the competition picks up pace. Also Super Talent’s RAID DRIVE is bound to be super fast giving a solid 370meg/second. This may be a great reason to rejoice for this is something truly fast and can shift the whole content of a DVD as quick as within 15 seconds. Agreed it was able to reach these speeds even earlier, but with the help of USB controllers of that time it was forced to bring down the speed to 300meg/sec. now with this latest controller, the firmware is capable of upgrading so that its total power is utilized.
There have been discussions of the RAIDDRIVE creating quite an eruption which is yet to be seen for experts are doing their job of testing RAIDDRIVE’s creating a hotter wave, promising extra quick speed. It is priced at $30.58 for a 54 gig drive.
Reports suggest that Samsung Galaxy Tab, being a single-core tablet would not meet the basic requirements to run Honeycomb, tablet-optimized OS version by Google. Apparently the Galaxy Tab owners would only be expecting that they get an update with Honeycomb.
Managing Director of Enspert, Bobby Cha while talking to PCMag said that Honeycomb requires a Cortex A9 dual-core processor for proper functionality. Until now, Nvidia’s Tegra 2 is the only chipset that has incorporated this processor and will be appearing in a number of Android tablets at Consumer Electronics Show that is to be held in the second week of January.
Cha also said that 1280 X 720 is the minimum screen resolution prerequisite, and therefore the Honeycomb-based tabs will have 7-inch screens or larger.
It is quite obvious that Samsung Galaxy Tab is well below the required specifications as it incorporates a 1GHz Hummingbird single-core processor, and comes with a resolution display of 1024 X 600. Also, as suggested by Samsung, Galaxy Tab would only be updated to “Gingerbread” i.e. Android 2.3.
Meanwhile, Google chose to remain silent about the requirements of Honeycomb, and did not even clarify if version number that is being talked about is 3.0 or 2.4. However, this would not be good news for the owners of Samsung Galaxy Tab, especially for the ones who have picked a set just recently expecting to enjoy Honeycomb capabilities on it.
Last December, Google’s VP of engineering division, Andy Rubin demonstrated Motorola’s Honeycomb tablet, but he did not reveal any clear details. It is only known that the Android version will support large-screen apps as well as software-based back and home buttons. Additional details are expected to trickle out as soon, as gadgets manufacturing companies start unveiling their forthcoming tablets.
The Buzz is that Motorola’s new tablet “Droid Xoom” and LG’s “Optimus Pad” are likely to be announced at Consumer Electronics Show, 2011. Both have been incorporated with dual-core processors and they would of course have Android Honeycomb. Many believe that other tablet manufacturers might not make it due to Honeycomb resource requisite issues.
Last year, with Android 2.2, the then latest version of Google’s Android OS, Google had indicated that it would not suit Android tablets. However, the same is been used so far in Samsung Galaxy Tab which is considered as one of the top Android tablets in the market.
We can expect Android hacking community which is a decent-sized community to get involved and attempt to bring Honeycomb to Galaxy Tab. However, even if they are successful in doing so, it will possibly be loaded with issues. This is because, if the 1280 X 720 screen resolution speculations are true, and the user interface of Google’s latest Android OS will not support 1024×600 screen. Galaxy Tab will need to crop or downscale the interface so that it works well on the 7-inch display of the tablet.
Honeycomb is expected to be out in the market by the end of January. Let’s wait and see whether these minimum specifications of Honeycomb are just speculations or if the Galaxy Tab will really be left out.
Valuable Guidelines For Performance Tuning Of MySQL Database Server
Any dynamically served website with enormous traffic and visitors normally depends on a strong and powerful Database Management System (DBMS) for storing data which can be reclaimed or retrieved by web servers in order to build web pages for the website visitors to read.
MySQL is one such Database Management System that is highly popular and widely used. Every time a visitor visits a website, the MySQL DB server is accessed at least once by the web server so as to assemble and display the web page to the reader.
It is very important that the MySQL server gives a superior performance which in turn improves the speed of the website, especially if the web host is loaded with traffic. Therefore, it is essential to learn the skill of performance enhancement of MySQL database server.
During one of the Google TechTalks, Jay Pipes who is the Relations Manager of MySQL Community for North America, gave a talk on the finest techniques and practices which can be implemented for enhancing MySQL server performance.
Jay Pipes is also the co-author of Pro MySQL which was published in 2005 by Apress. Pro MySQL comes with all the latest features of MySQL 5 along with a thorough analysis and discussion of MySQL server architecture, transaction processing, storage engines, benchmarking and other scenarios of advanced SQL.
Even though the talk by Jay Pipes is an old one, it definitely provides some valuable information on MySQL performance tuning. In the talk, Jay Pipes has spoken about the key areas that you need to focus on while fine-tuning the performance of database servers and applications.
He has also explained how webmasters or database administrators can get the best results by applying some useful intermediate and complex MySQL skills.
The topics discussed in the talk are mentioned as follows:
Core Concepts of Benchmarking and Profiling – Benchmarking provides you with a track record. While benchmarking, change just one thing at a time and re-run the benchmarks in order to efficiently keep a track of the outcome of the change made. Record everything related to the benchmarks including the configuration files, information on OS, hardware, MySQL etc.
Particularly with MySQL, remember to disable query cache every time you run the benchmarks. Profiling helps in diagnosing a running system. Get familiar with the access types and make use of Slow query Log and mysqldumpslow. Make use of mytop in order to catch long-running queries.
Common Issues/ Problems with Performance – The various sources of problems include poor indexing choices, inefficient schema design, improper coding practices, improper tuning of server variables and hardware or/and network bottlenecks. These issues need to be properly focused on and resolved.
Schema issues can be resolved and faster performance can be achieved by using smaller data types, narrower index records, more records per block and fewer reads. Making use of proper indexing (i.e. covering index opportunities, proper selection of index fields, removing redundant indexes, etc) plays an important role in performance enhancing.
Following proper coding guidelines (i.e. using stored procedures, using counter tables and calculated fields, using joins, eliminating correlated sub queries etc) is equally necessary.
Tuning of Server Parameters – Tuning of server parameters provides a speedy solution but a temporary one. Having awareness about global and per thread parameters is very much necessary. Try making small changes at a time and test to check the effect. Turn the query cache on and give it a size. Within the configuration files, set a size for “query_cache_size”.
Maximum memory has to be allocated for saving data and index pages. Memory is an affordable, fastest and easiest way to enhance MySQL performance.
Studies by Dr. Andrew Steckl of at the Cincinnati University Nanolab, states that electrowetting works equally well with a paper as well as a glass substrate. Electrowetting is that method where current e-ink shows work. Even if it is paper, the screens cannot be removed, because the costly part of the e-ink screen is not everything but the substrate. This does not mean that the display can be folded or flexible. It all depends on how the mechanism, fluids and circuits manage the deformation applied, something out of the topic.
Electronic paper/e-paper/electronic ink display, all sum up to the same thing. It is a display created to ape the appearance of ordinary ink on paper. It is different from ordinary displays which take the assistance from backlights to shine on its pixels; whereas e-paper reflects light like ordinary paper. It can contain text and images indefinitely without pulling electricity, at the same time letting the image to be changed later.
The e-paper was first developed in 1970s by Nick Sheridon at the Xerox’s Palo Alto Research Center. Later, in the 1990s, e-paper of a slightly different kind came into existence by Joseph Jacobson, who later founded the E-Ink Corporation. Electro-wetting display [EWD] is based on controlling the shape of a confined water/oil interface by an applied voltage. Displays based on EW have several attractive features.
The changing of white and colored reflection is quick enough to exhibit video content. It is a low-power low-voltage technology where the displays can be made flat or thin depending on the effects. Also, this technology shows a special path directed to high brightness and full colour displays resulting in displays of a much superior quality[ almost 4 times brighter] when compared to LCDs.
Examples of commercial electro wetting displays are inclusive of Liquavista  |TR|  PVI and ADT . But it does have its own drawbacks too. The e-paper technologies have a very low refresh rate when compared to other low-power display technologies as LCD. This does not allow implementation of highly sophisticated interactive applications [using fast moving menus, mouse pointer or scrolling], which can be done easily on handheld comps.
Let’s say it like this, a document cannot be easily zoomed without either extreme zooming or very slow zoom. Another point which can go down as a disadvantage would be that an imprint of an image may be seen even after refreshing parts of the screen. These imprints are commonly called ghost images and the effect is known as ghosting.
HaxOrs have found out how to manage the Kinect’s motors ( official website)from Windows, a huge leap in the direction of the entire control of the latest Microsoft Gaming Product. This demo describes the functions of motors within kinect responding to a tiny app on the desktop. You never know, it might turn out to be just the opening for the $20,000 reward offered for an open-source kinect!
But it is not the love of money which provoked the hacking! It is believed that the person behind this is the same person who was responsible for the hacking of Play station Eye in 2008 and he has already managed to obtain video streams from both cameras to output to his PC. But there has been no word of his releasing the code. It was tracked just 3 days after its releases in the US and it is not yet launched in UK!
