First OSUM Meeting Part 1
Gaetjens Lezin spoke about the online community,
OSUM, available to students on campus. “I am happy over 40 people showed up to the event,” said Lezin. “They were all interested in
the Open Source Software and the resources Sun Microsystems has to offer at
He also outlined the upcoming events in the club. “The install fest with ACM and I triple E is coming up the week of the 16th,” said Lezin.
Lezin outlined the SUN academic initiative certification discounts. “For those interested in getting certifications recognized industry wide, the Sun Academic Initiative has the resources you need to help accomplish your goals,” said Lezin.
There are also benefits of Open source software for students, faculty and the university. “Some of these include opportunity to collaborate, access to tutorials and webinars and a competitive edge on the workforce, and best of all its all free!,” said Lezin.
There was also a small discussion about ZFS and D-Trace. “D- Trace allows you to profile all aspects of your system,” said Lezin.
Lezin said that he thought the event went well. “They seemed very interested in the information we had to offer.”
First OSUM Meeting- Part 2
Harrison Fisk, a MY SQL staff
support engineer presented at the first OSUM meeting in the Engineering building in room N22. Fisk graduated from
Fisk explained that he helped develop software that would run large websites such as Wikipedia and Facebook. “Many modern websites use similar software,” said Fisk.
The reasons for the usage of these software packages included their ability to modify, ability to debug and the large variety of licenses available.
Architecture, said Fisk, for very large websites is important for their functioning. “Live wire was the first to develop this software,” he said.
Vertical scaling and horizontal scaling, said Fisk, were two ways to expand the capacity of web servers. Horizontal scaling was to add more systems whereas, vertical scaling was to have a larger single system.
Fisk also explored the construction of large websites. “Facebook has a lot less servers, and a lot less traffic,” he said.
Static data was easier to manage than dynamic data, which is constantly changing, said Fisk. These two systems of organization would factor into which web server was chosen for a respective web page. “Apache is very common to use because it is extremely flexible.”
Programming language, said Fisk, isn’t that important. “When you can just add more machinery, there is little need for it,” he said.
Fisk examined different programming languages. “Google just loves their python,” he said.
MYSQL is developed and supported by SUN. “This is what I do,” said Fisk. “MYSQL is very flexible because you can add modules to get the functionality that you want.”
Sharding, said Fisk, is a very common technique used in data bases. “It adds the ability to scale writes horizontally,” he said. “User IDs are broken up onto different servers instead of stored on one massive server.”
A lot of management, said Fisk, is needed to organize the data. Fisk presented a sharding diagram which exemplified how data is divided.
Fisk also touched upon different operating systems. “Linux is the most popular by far,” he said. “It comes down to preference.”
Security, said Fisk, is another concern when it comes to choosing an operating system. “In example, Wikipedia is a huge target for hackers.”
After The Meeting
Fisk said he wanted students to learn how Open Source is used in modern web applications, from his presentation.
From personal experience in the Industry, Fisk said, that he learned how Open Source is able to scale to the largest requirements.
“Open source is commonly used in the industry,” said Fisk. “Most commercial organizations are using it.”
According to Fisk, students with knowledge of MYSQL would be better prepared to enter the market place. “MYSQL is the cutting edge of where the IT industry is going.”George Stehlik, a senior CS and physics major was an attendee at the meeting. “It was a good meeting,” said Stehlik. “I never knew about shark.”
