News Ways to Find an IT Job in a New Web World {4}

by Cary C
The article in question discusses six Web 2.0 tools that Information Technology people who are currently seeking a new job should be aware of.  “It states that just over fifty percent of all IT workers are actively looking for a new position and that about forty-six percent of these workers haven’t searched in over five years”.  Of course, the technologies used on the Internet have changed greatly in the last five years and during that time frame four tools have emerged as the dominant players in social networking and job hunting.  LinkedIn, Facebook, YouTube, and Twitter have changed the way recruiters seek people to fulfill the open positions they have.  Due to the large number of people who are currently unemployed, recruiters are being swarmed with resumes which often come from desperate, unqualified people.  As a result, these recruiters are posting jobs less and searching the social network sites for people with the skills that they are seeking.  While it is becoming easier for the recruiters to find job seekers, it is becoming increasingly more difficult for job seekers to keep their personal life separate from their professional life. read more...

Google’s Push for Universal Online ID {3}

by ChihWei H

Google’s new social network service, Google+, has a bigger agenda than a mere Facebook replacement. Google’s Chairman, Eric Schmidt, admitted why Google is pushing for real name usage on their network site is because they see it as a “identity service.” This kind of service is nothing new. Microsoft has long been pushing their Windows Live ID as an unified gateway to their service. A lot of websites also allow users to sign in with their facebook account. However, analysts pointed out why G+ would like users to use their real names. The reason is simple, real name is more valuable to advertisers than fake names. Real name users are easier for advertisers to target, even figure out their age, social status and demographic. read more...

Social Network Face Book and Its Data Warehouse {Comments Off on Social Network Face Book and Its Data Warehouse}

by Tuyen H

         This article talks about MapReduce (MR) platform with parallel data access. MapReduce is introduced by Google in 2004 for supporting multiple accesses of data. It has been written in many languages such as C++, C#, Java, and even PHP. Famous Social Network Face Book built its massive data warehouse by using the MapReduce technology. The authors also compare the MapReduce technology with database management system (DBMS) “MapReduce complements DBMSs since databases are not designed for extract transform- load tasks, a MapReduce specialty.” Indeed, the combination of MR and DBMS create a powerful of database system. This combination allows big companies to build their database warehouse where they store a lot of information. For example, Face Book store more than 800 million users’ data and information. Google’s data warehouse stores more than 850 TB for supporting user searching. Finally, the authors mention that those technologies are not competition but complementary. 
        This article mentions data warehouse and database technologies such as MapReduce (MR) and database management system (DBMS). Those technologies are really helpful because they allow people to build massive data warehouses. For instance, Google’s data warehouse like a world library; it support business and study around the world. It also likes the world knowledge. In my work place, every time we have questions we “ask” Google. In school, when I research I also “ask’ Google.
        As you know the Jasmine Revolution happened with support of social network like Face Book and Twister. If there are not any database technologies such as MR and DBMS, there is not Face Book or Twister. Therefore, the Jasmine Revolution will not happen.  Data warehouse also use to store much important information that supports government, organization, and education. Imagine that, if the government does not have the database, how can it work? The IRS cannot collect tax. The DMV cannot manage vehicles and so on. I think data warehouse is really helpful, and both RM and DBMS are revolution of the database technology. read more...

Have you ever noticed the Facebook, and Twitter buttons on many of the web pages that you visit? The buttons allow you to share content that you like, with your friends on these social- networking websites. But the companies that run these social-networking websites also collect information about the sites that you have visited that contain these buttons called widgets. Both of the companies collect information about the sites that you visit even if you don’t hit the button. The companies have stated that they collect the information for the purpose of advertising and that they only keep the information for a small amount of time. The Wall Street Journal states that these widgets have been added to millions of websites within the past year and that they appear on a third of the 1,000 world’s most-visited websites. Facebook says that the widgets work by using cookies that are placed on your computer when you log onto Facebook or when you register for it. The cookies allow Facebook to see what users are looking at on any of these sites that contain these widgets.  The scary thing about these widgets is that, they are contained on websites that can be about personal subject like depression and bankruptcy. Members of Congress have introduced new bills this year that would eliminate some of these privacy concerns, but until they become law we will continue to be watched. read more...
