The need for multiple data at same time makes it necessary that data need to be duplicated and multiple copies of the same data are circulated to meet the diversified needs. And if the quantity of data is large, then you need to have something that can store volumes of data and transfer it to the destination. Microboards Blu Ray duplicators are categorized amongst the prominent SATA driven DVD duplicators making the buzz in the market today. The duplicators are available in variety of capacities and have the efficiency to duplicate from few DVDs to thousands of DVD copies in just few minutes, from the master DVD. Microboards Blu Ray duplicators have high performance, and they record the media seamlessly with no loss in bits, and the data quality also remains intact.
There are models available in Blu Ray duplicators that feature world's most advanced functions in the form of DHP technology'. The technology creates equal space partition on the hard drive as that of master disc, and in this manner ensures maximum of HDD space. There is also integrated in the duplicators 'Master Error Proof technology' which allows the user to replace corrupted master disc and you will not be wasting your blank DVD. Another popular DVD duplicator is Tower DVD Duplicators manufactured by Blu Ray, LG etc. and which are widely used for commercial purposes. The DVD duplicators are ideally designed as tower systems that work well to duplicate most DVD formats including DVD+R, DVD-R and DVD+R Dual Layer. Tower DVD duplicators come in package of 3, 4, 5, 6 and 10 DVD layers and gives the user plenty of opportunity to mass duplicate the DVDs. The best part is that differentiates Tower DVD duplicators from a Standalone DVD duplicator is that you don't need a computer system to duplicate the DVD. And this also accounts for the reason why there is no need for the USB 2.0 device. Whether it is a Microboards Standalone DVD duplicator or a tower system, you are always assured against duplication session failure. There is high reliability and super duper speed to allow duplication of DVDs. The best part is that there will be no potential damage to DVDs.
Microboards is a symbol of trust and security. The duplicators manufactured by them are adaptable to work with or without computer, and across the platforms. Try one for your requirements and see the difference!

A leading manufacturer of hard disk drives for enterprise, desktop, mobile computing and consumer electronics applications uses blocks of intellectual property (IP) in its next-generation disk controller application specific integrated circuits (ASICs). Some of these IP blocks are used in several different products, making it an imperative that designs be exhaustively verified under all possible operating conditions prior to release.
In the past, the manufacturers' ASIC designers relied on digital simulation as their primary means of verifying IP blocks. They also employed automatic constrained pseudo-random testbench generation to construct thousands of different combinations of commands and data packets. Early in the design of a new compute-intensive IP block, the design architects calculated that it would take approximately 500 CPU-years to simulate all the test cases necessary to test this particular design. With a six month design schedule, it was clear that simulation alone would not be adequate. That's when the designers decided to evaluate several hardware-assisted verification platforms. This proved to be the ideal solution for delivering a quality product within the tight design schedule. In this case, the hard disk drive manufacturer selected EVE's ZeBu-ZV platform.
The IP design presented unique verification challenges. The block had a 32-bit interface, over which commands and data were loaded into the block using a packet-based protocol. Once set up, it then processed the data for about four seconds of real time, after which it presented the results over the same 32-bit interface. At an operating speed of 150 MHz, four seconds represented 600,000,000 cycles. The design team needed to run several hundred thousand of these test cases to fully verify the design.
On this project, a digital simulator/testbench generator combination was used for initial verification runs to prove basic functionality, using about 50 tests per command. Once this verification methodology was generally functional, the designers switched to the combination of the hardware-assisted verification platform and testbench generator, which enabled them to run thousands of tests for each command.
To maximize performance, synthesizable transactors were used as the interface between the testbench code on the PC and the emulated IP block in the verification platform. Transactors performed the conversion from high-level commands and data packets to bit-level signals using the hardware-assisted verification platform. The SCE-MI standard from Accellera defined how the transactors were written. They consist of an application program interface (API) on the software side to exchange high-level packets or messages, and a synthesizable bus-functional model (BFM) or state machine mapped onto the hardware platform.
To further accelerate simulation, the design team took advantage of a property of this particular IP block: The only interaction between the testbench and the IP block occurred during the initial setup of the test and the downloading of results at the end of the run. In between these two interactions, the design executed a large number of cycles with no external communication. The designers exploited this by making the verification platform run in lock-step mode with the testbench generator only during these interactions, and switching to a 15MHz clock supplied by the verification platform in between these accesses. To implement this solution, they changed the main clock of the design to switch between two inputs: the clock coming from testbench generation and a clock generated by the verification platform's on-board clock generator.
Using this hybrid approach, the testbench generator produced each new command and data combination, and then transferred the packet through a C function-call to the verification platform transactors. The testbench generator then switched the verification tool to the fast clock and initiated the test. It was able to run the tests at 15 MHz, equivalent to 1/10 of real time. In 40 seconds, the test would finish and it would signal the testbench generator that it was ready to present the result.
Meanwhile, the testbench generator was computing the expected results in software, using the same algorithms implemented in the IP block. Once the hardware-assisted verification platform and the testbench generator completed their respective runs, they would compare their results and flag any differences that occurred as errors.
The design team was surprised that with the first exposure to the system it took them only two hours to get their IP block compiled into the verification platform and running correctly. With a few more weeks of effort, the team had implemented and debugged the transactor interface and had the system running at 15 MHz.
In the first few days, the designers identified 25-30 new bugs in the design, which had escaped detection using simulation without hardware-assistance. In the five weeks to follow, they ran the hardware-assisted verification platform 24 hours per day, 7 days per week, generating hundreds of thousands of additional test cases. Through these runs, they found four additional bugs that were obscure corner cases related to specific sequences of commands. These bugs would have surfaced during product testing, but would have necessitated ASIC respins at a cost of $500,000 or more.
The designers of this hard disk drive manufacturer plans to continue running additional test cases on their hardware-assisted verification platform 24x7 until the resource is needed for another project. Since it takes only one hour per week to kick off new jobs and check the results of the previous runs, there is little reason not to run the additional tests for added confidence. Their hardware-assisted verification platform has become the keystone of their design strategy.
WAN boot is a "new" method for installing a machine running the Solaris Operating System from a Solaris JumpStart server over the network. WAN boot has a lot of enhancements compared to the "old" installation method via bootp and should be used for network installations if possible. (Note: WAN boot is only supported on machines with SPARC CPUs. You cannot use WAN boot on machines running the Solaris OS for x86 platforms.)
This article describes how to use WAN boot on machines that do not have WAN boot support in the OBP and cannot use a CD-ROM for WAN boot.
This method requires:
Access to the console of the machine
The Solaris OS running on the machine
Details
The only file that is necessary for WAN boot is /platform/`uname -i`/wanboot. Therefore, to get WAN boot from the disk to work, it is sufficient to copy the current version of the WAN boot binary from (for example) the Solaris Installation CD-ROM to the directory /platform/`uname -i` on one of the slices of any local hard disk of the machine.
The Steps
1. Configure the machine to install as a WAN boot client on your installation server.
2. Select one of the existing slices on one of the internal hard disks of the machine to install for the WAN boot binary. For example, this can be the existing boot slice or any other slice on the disk. You can also put the WAN boot binary on the disk on which you want to install the Solaris OS, because the disk is only used to read the WAN boot binary. After the WAN boot binary is read and executed, the disk is not used anymore for the boot process.
3. Make the selected slice bootable using installboot if the slice is not already bootable; that is:
If in doubt, issue the installboot command. (It won't hurt if the slice is already bootable.)
4. Halt the machine and issue the following boot command at the ok prompt:
ok> boot mydisk -o prompt -F wanboot - install
Here mydisk is the disk device (either a device alias or the real device name). If you use a slice other than the default slice for the WAN boot binary, the command should look like this:
ok> boot disk1:b -o prompt -F wanboot - install
Here disk1 is the device alias and the letter after the colon specifies the slice to boot from: a is slice 0, b is slice 1, c is slice 2, and so on.
5. After a short time, the normal WAN boot prompt should be printed and you can enter the necessary information for the WAN boot process and continue the WAN boot installation the normal way.

Example 1 shows the machine output from step 4 in the preceding description. Note: Some output has been replaced with "x" characters.

The advancements in technology have made possible the proliferation of crimes that used to be depicted in the movies only and which were very far from reality. However, there are existing crimes that are now spreading like wildfire because of the lack of security in using the Internet, One such crime closely related to Internet use but which can also be committed in other ways is identity theft. Identity theft basically operates the same that the ordinary crime of theft does. The difference is that in identity theft, what is stolen is the identity of a person.
Identity is considered a crime because it is the act of assuming or using the identity of another person without his consent. Identity theft usually causes injury to the person whose identity has been stolen. It is usually committed for financial gain, blackmail or even espionage.
This crime has grown so widespread that the United States Congress has enacted the Identity Theft Penalty Enhancement Act to punish those found suing another person' identity without his consent. The criminal gets an additional two years in jail if he uses the stolen identity to perpetuate another crime. Another five years is added to the jail term if the crime is used to promote terrorism.
So how is identity theft done? Identity thieves are one of the most creative people in this planet and they will do anything to get information about the people whose identity they are planning to steal. This includes rummaging through the target victim's garbage to sift important information about the person's identity which they can use in perpetuating the crime.
Some identity thieves use computers and sophisticated programs like spyware to get financial information about their target victims. Hacking another person's computer is a method often used by identity thieves to commit the crime.
The proliferation of Identity theft can be blamed on the ease with which financial transactions can now be made. Credit card companies readily approve applications without even physically dealing with the applicants. These companies approve the applications based on documents that the applicants send by snail mail or online and the companies send the approved cards by mail. Revealing financial information through the telephone can also be a magnet for identity thieves. These criminals have access to high technology gadgets and they can eavesdrop on telephone conversations. Sending information through the Bluetooth technology can also be easily intercepted by identity thieves.
Everyone is in danger and any person's identity can be stolen. Thus, a person should be careful in revealing financial information especially if such information is being asked for no reason at all. To avoid being victimized by identity thieves, a person should consider the following safety measures:
1. Always be careful in sending and receiving financial information through snail mail because mails can easily be intercepted by thieves.
2. Never throw important financial and other information in the garbage without shredding them first. Identity thieves can masquerade as garbage collectors and sift through a mountain of financial information about the prospective victim.
3. Never reveal financial information over the phone. Anybody can call someone on the telephone and pretend to be a bank officer. When such information has to be given to any office, it is better to visit the office and personally hand in the information to the right person.
4. Always inspect bank transactions and look for any irregular payments or withdrawals.
5. In the same manner, always check credit card bills and cross check with purchases and other credits to make sure that the charges are correct and not made by another person.
When it comes to identity theft, no one is really safe and the best thing to do is to be careful and wary of revealing any financial information. It is best to incur a little delay by verifying the identities of people asking for financial information rather than to suffer financial distress later on.
Remember that identity thieves are very creative and they can get any information they want. They can even be getting a person's financial information this very moment while the target is using his computer. With all the convenience of technology, any person can be a victim of identity theft.
