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.

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.

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.

Inkjet Printers are not only getting better but they also becoming less expensive with time. A branded inkjet cartridge can cost you $30 or more and if your printer uses a multi-color ink cartridge system ink costs could easily $1000 to replace all inkjet cartridges for your entire inkjet printer.

The growing business of inkjet printers has brought about additional benefits to them. Manufacturers have built their business around the supplies rather than the printer itself. They have made the inkjet printers an inexpensive commodity sometimes selling them at lower cost or may be even less thereby making long term profits from inkjet printers.

An Inkjet printer uses a unique printer mechanism, which provides quality printing. They transfer tiny droplets of ink directly to the page. This is the reason why you will find most photo printers are inkjets. If you want to print photos at home, photo inkjet printer would probably be a perfect choice. For instance, if you want to print few photos, few e books or print any other project work an inkjet printer would help your cause. Inkjet printers are far less expensive than laser printers.
