Have you been PWNed!? {Comments Off on Have you been PWNed!?}

If you were affected by Lulzsec’s attack on Sony or any of the other numerous targets you may have had your information compromised. This summer there seemed to be no shortage of news of hackers and their victims, and no one seemed safe not even the government or their affiliates were safe from hacking or denial of service attacks. While people suffered and business were thoroughly embarrassed there was opportunity to be had. Recently several sites like pwnedlist.com have sprung up and have offered people a chance to check their usernames and emails against databases of known lists that Lulzsec released of compromised accounts. “Among security experts, 2011 has already been anointed “Year of the Data Breach.” Millions of people have had their email addresses, user names, passwords and more clipped by crackers breaking into the data stores of companies like Sony, Epsilon, Google, Citigroup and Sega. What’s more many more less publicized breaches occur daily. So Pwnedlist couldn’t be coming online at a better time.” (Mello jr, 2011) read more...

US should embrace the cloud! {1}

by Stephen O
Summary

Imagine in a couple years that cloud computing was twice as big as it was now. There were government standards when it came to cloud privacy and because we had embraced cloud-computing America was the clear leader in cloud computing. We could have that , if  The United States Government and the Industry would work towards spreading cloud computing. The TechAmerica Foundation makes the point if the Industry and the US Government worked together we could all benefit from. The U.S. Government needs to make the first step though.  “The U.S. government can help grow the nation’s cloud computing market by assisting private companies in the development of cloud security standards and by encouraging cloud providers to allow data portability among them, a new tech industry report recommended. The U.S. government can also “lead by example” by stepping up its use of cloud-based services and by revamping its procurement and budget processes to encourage agencies to buy cloud services” (Gross, 2011) read more...

Time to move on to something…better {1}

by Stephen O
Summary:

When is it time for something new? When is a good time to trade up? Is it similar to buying a smart phone? Waiting for the new model later that year? Is it when the industry chooses a standard like Blue Ray or VHS? On the other hand, is it like buying a car and it no longer can perform reliably the duties we purchased it for? When is it time for us to transition to the next generation of Data Modeling?  In the article “Toward a Next Generation Data Modeling Facility: Neither the Entity-Relationship Model nor UML Meet the Need” the author went about explaining why perhaps it is time to move on towards the next generation of Data Modeling.  They defined five wanted characteristics of a Data model. read more...

The Importance of Index Blending {Comments Off on The Importance of Index Blending}

by Alexander V
Summary:

The article was about “Index Blending” and its contribution to discipline specific research. “Index Blending is the process of database development whereby various components are merged and refined to create a single encompassing source of information. ” Index Blending combines the specific indices of other databases and other important components in order to create a single index for a particular area of study. One could say it is a “frankenstein” database where all the best resources for research are combined into one index. The process of Index Blending is very long and detail oriented. The first and most important step of the process is to determine what the problem/need is. In this instance, an area of study does not have sufficient resources and requires a more comprehensive index. The need for a more comprehensive resource is usually determined through: conducting surveys, discussions with users, and looking currently available resources. Through this process vendors determine what resources to add, remove, focus on, and or expand upon. Examples of Index Blending used by the author are EBSCO’s development of the databases Communication & Mass Media Complete and Hospitality & Tourism Index . read more...

ERP and the users’ view {Comments Off on ERP and the users’ view}

by Stephen O
Summary:

All of us use an ERP. Whether you knowingly use it, use it in disdain, or unknowingly do so. If you are a student at California State Polytechnic University, Pomona you are familiar with Bronco Direct. It is the software that we use to add/drop classes, search for classes, check holds, register for tests, and see when your financial aid disbursement is. Most college campuses have an ERP System, in fact, Mount San Antonio Community College switched just a couple years back to their own My.Mtsac ERP software. Now before I go any further ERP stands for Enterprise resource planning.  It is the software that is used for many business functions such as  Finance/Accounting, Human Resource management, supply chain management, project management, customer relationship management, data services, and access control. “. They evolved from standard inventory control packages to material requirements planning (MRP) and manufacturing resource planning. Enterprise resource planning (ERP) is now considered to be the price of entry for running a business.” (Yu-Min, 2006) I know if you are like me you cringe when it comes time to register for classes, and Bronco Direct otherwise known as Peoplesoft, is down.  ERPs can be complicated, complex, and expensive to install and there has to be some way of evaluating to see if an ERP system is even necessary and once it is installed, just how successful such a system might be. In Taiwan, they used 264 people and subjected them to a newly installed ERP system. “The results suggest a ten-item instrument to measure three components of ultimate-user satisfaction in an ERP environment: ERP project team and service, ERP product, and user knowledge and involvement. This study has conducted a rigorous scale development procedure to establish a reliable and valid instrument for measuring ERP ultimate-user satisfaction.” (Yu-Min, 2006) Through this study they established a valid way to measure ERP Ultimate-user Satisfaction. read more...
