3.03 PSP Downgrade.

So you’re looking a 3.03 PSP Downgrade? well this article may help you out.

First and foremost, you need an unpatched copy of Grand Theft Auto Liberty City Stories.

There is no other way that you can downgrade any PSP over 2.81 without it. Now for some reason people don’t seem to appreciate this fact and will spend hours upon hours searching the Internet for other ways to downgrade with out the GTA. Let me save you time, there is no other way to downgrade any PSP above 2.81 with out the unpatched GTA.

In late 2005 a vulnerability was found in the way the PSP version of GTA: Liberty City Stories processes saved games. In December 2005 software was developed to execute unsigned code on PSPs with firmwares 2.00 through 2.60. In April 2006 firmware 2.70 was released and patched the exploit, however, as of January 25, 2007 it was discovered that Sony did not completely patch the exploit, and unsigned code may be run on 3.03 firmware, a 3.03 downgrader was released 3 days after the exploit was found. Also, new copies of GTA: Liberty City Stories patched the exploit as well, preventing it from being executed on other firmware versions. Since then homebrew has advanced to the point that a copy of GTA: Liberty City Stories is no longer needed to run unsigned code except on firmware versions 2.81 to 3.03. Sony has now blocked the GTA exploit for good with the release of the 3.10 firmware update and later subsequent firmware udates.

So how do I know if I have the right GTA for a 3.03 PSP downgrade? Well, it’s quite simple really. Get your copy of GTA Liberty City Stories and put it in your UMD drive, now scroll to the game folder and you will see a “UMD update” option. Now, if this says “Update 2.00″ then you have an unpatched version, if it says “Update 2.60″ then you have the patched version which is no good for a 3.03 PSP downgrade.

Information technology has transformed the way we live and the way we do business. ERP, or Enterprise Resource Planning, is one of most widely implemented business software systems in a wide variety of industries and organizations. In this short article, we’ll try to concisely explain the basic yet important concepts relevant to ERP.

What is ERP – ERP is the acronym of Enterprise Resource Planning. ERP definition refers to both ERP software and business strategies that implement ERP systems. ERP implementation utilizes various ERP software applications to improve the performance of organizations for 1) resource planning, 2) management control and 3) operational control. ERP software consists of multiple software modules that integrates activities across functional departments – from product planning, parts purchasing, inventory control, product distribution, to order tracking. Most ERP software systems include application modules to support common business activities – finance, accounting and human resources.

ERP Systems – ERP is much more than a piece of computer software. A ERP System includes ERP Software, Business Processes, Users and Hardware that run the ERP software. An ERP system is more than the sum of its parts or components. Those components interact together to achieve a common goal – streamline and improve organizations’ business processes.

History of ERP – Enterprise Resource Planning (ERP) is the evolution of Manufacturing Requirements Planning (MRP) II in 1980s, while MRP is the evolution of Inventory Management & Control conceived in 1960s. ERP has expanded from coordination of manufacturing processes to the integration of enterprise-wide backend processes. In terms of technology, ERP has evolved from legacy implementation to more flexible tiered client-server architecture.

Benefits of ERP – ERP software attempts to integrate business processes across departments onto a single enterprise-wide information system. The major benefits of ERP are improved coordination across functional departments and increased efficiencies of doing business. The implementation of ERP systems help facilitate day-to-day management as well. ERP software systems is originally and ambitiously designed to support resource planning portion of strategic planning. In reality, resource planning has been the weakest link in ERP practice due to the complexity of strategic planning and lack of adequate integration of ERP with Decision Support Systems (DSS).

Cabling your home for computer network – still a requirement?

With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let’s take a look at some pros and contras:

1. One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks to mere 1 sec or less on wired 1000MBit/s Ethernet connection. Same principal applies to transferring files, backing up files on other computers in the network etc.
2. It is not possible today and with all probability will not be possible in the future to transmit power needed for your networking device via the wireless link. Unless, of course, you would be willing to be subjected to very high levels of microwave radiation. Thus a device that was marketed to you as “un-tethered” will in fact be very much tethered via the power cord or will have to be re-charged every so often. The power requirements are increasingly important for devices that are expected to be always online, such as phone sets. Therefore it is best to have it connected via a cable that can deliver both power and the communication signal at the same time.
3. Wireless communications are very much proprietary and require whole gamut of conversion equipment to transmit multi-media signals. The same CAT5E cable can without any modification support phone, computer network, balanced line level audio signal, baseband video signal as well as host of other, more specialized, control applications’ signals. With inexpensive adapters called “baluns” the same cable can carry significant number of channels of broadband television or carry a baseband video, such as security camera output, through great distances. All of those applications, except the computer network of course, will require specialized expensive conversion equipment if they needed to be transmitted via a Wi-Fi link.
4. The cost benefit of not running wires around the house is not as simple as issue as it seems. Having installed a wireless network at home you have only eliminated the need to wire for a single application – computer network. A modern home, however, requires all kinds of wiring to run even without regard to computers. The power and phones are obvious examples, as well as thermostats and security systems. Pre-wired speakers are common and most homes today have intercom systems as a desirable option, and those also require extensive wiring. It is very likely that the same contractor running the intercom or security cables is qualified to run computer cables – CAT5E or better. If you are building a home, you should definitely check if computer cabling option is available in your new home, and our advice is to go ahead and purchase it before the walls close. It is going to be a pretty involved and expensive procedure to install the cables later. As an added cost benefit of a wired computer network you will find that all modern computers ship with wired Ethernet network interface card included, and the latest models ship with 1000MBit/sec cards that are essentially free for the computer’s owner.
