Computer Science

Computer Science can be done as a major in the Bachelor of Science degree or by choosing courses in the Bachelor of Information Technology degree that have a particular focus.

This is where one gets to design algorithms, mathematically figure out their efficiencies, and actually gets to write out code to implement the said algorithms in practice. For those who enjoy figuring out just how the code works, and generally code monkey around – this should be the program of choice.

Software Engineering

Probably the closest program to Computer Science. If Computer Science is about writing code, then Software Engineering is thinking about writing the said code.

Not quite the same level of involvement with the code. Software Engineering is more abstract, more “larger picture” focused. Lack of Pointer kung-foo is made up with non-technical skills such as communication and presentations. Management material education.

Computer Engineering

In many ways similar to Software Engineering, the Computer Engineering discipline deals with design of specialized type of software, and incorporates more hardware material into studies.

Here you get to design your circuit board, and program it too! Lower level coding, but for actual physical gadgets. Pretty cool.

Mechatronics Engineering

Mechatronics Engineering is an interesting program as it tries to integrate every other discipline from the above chart. Described as a mix of Software, Hardware, Mechanical parts, and lots of Maths, there was still room to include a couple of programming courses into the program’s schedule.

The broad scope will likely be appealing for those interested in picking up on a lot of new and varying material. Very management material course, as the education promises a middle ground that will unite all the other disciplines that are deemed to be unable to communicate well with each other.

Maths / Physics

There’s also an option to ditch the computers all together, and pursue the pure logic, theory, and problem solving with the underlying Mathematics. Computer Science is inherently mathematical in nature, and to some there is an appeal in this direction of problem solving by numbers, theory, and without limitations and bounds of programming languages.

From Akamai to XCalibre, a new Forrester Research report examines intriguing cloud computing vendors. Get to know them: Like it or not, people in your company are already experimenting with the cloud, Forrester warns.

March 11, 2008 — CIO — Cloud computing looks to be a “classic disruptive technology,” says Forrester Research in an interesting new report published yesterday. For enterprise IT shops, cloud computing still poses some real risks, including an almost complete lack of service-level agreements and customer references, plus some genuine security and compliance concerns, according to Forrester. But even so, IT shops are tapping into cloud services for targeted projects: “There’s a high likelihood that developers inside your company are experimenting with it right now,” writes senior analyst James Staten in the report,”Is Cloud Computing Ready for the Enterprise?”

That analysis meshes with what we recently reported hearing from CIOs in “Cloud Computing: Tales From the Front.” The cloud isn’t new per se; enterprise IT has had access to the Internet and software-as-a-service for years. But now, some vendors are giving enterprises the chance to run not only hosted apps but also custom-developed apps in the cloud—with great flexibility to scale computing power on short notice, and to pay only for what computing power is used. Enterprise IT sees the promise and is experimenting, cautiously.

Which cloud computing vendors should be on your radar screen now? In its report, Forrester cites 11:

Akamai
Amazon
Areti Internet
Enki
Fortress ITX
Joyent
Layered Technologies
Rackspace
Salesforce.com
Terremark
XCalibre

Akamai, Amazon and Salesforce will be the most familiar to enterprise IT. Akamai offers application performance services that speed up apps for users of cloud services, while Amazon offers the Amazon Elastic Compute Service (EC2) and storage in the cloud. Salesforce is pushing hosted apps and what it calls Platform as a Service, to help developers create new software in the cloud.

Terremark, Layered Technologies, XCalibre and startup Enki all play more behind the scenes in the hosting business that fuels and manages the cloud.

Also prominent at the moment is 3Tera, maker of AppLogic, which Forrester describes as “cloud computing infrastructure software” and a “grid engine.” Basically, this is enabling software that lets a hosting provider put customer software in the cloud with a minimum of fuss, for starters. AppLogic works on physical servers and virtualized ones, enables cost-based reporting, and runs many applications “without redesign or reprogramming to a grid API,” among other benefits, Forrester notes. Check out the report for more details on all the vendors and Forrester’s take on the competitive landscape.

No doubt, cloud computing, especially as Amazon envisions it, is in its early days, complete with hype and confusing jargon.

Nonetheless, for IT execs, the sooner that you tune into how people in your enterprise are playing with the cloud, the better, Forrester’s Staten says. “Even if IT can’t justify leveraging clouds, your business units will,” he notes in the report’s conclusion. “Cloud is a compelling business proposition, infrastructure they can provision with a credit card, with low barriers to entry and to exit. Rather than block their efforts, learn from them.”

Ruby on Rails is a free web application framework that is intended to increase the speed and ease with which database-driven web sites can be created.  Ruby on Rails is an open-source Web application framework written in Ruby that closely follows the MVC (Model-View-Controller) architecture. This project, which is written in the Ruby programming language, is also known as Rails, or RoR.

The fundamental principles of Ruby on Rails are Convention over Configuration (CoC) and Don’t repeat yourself (DRY).

“Convention over Configuration” means a developer only needs to specify unconventional aspects of the application.

“Don’t repeat yourself” means that information is located in a single, unambiguous place.

The Rails programming conventions allow you to write fewer lines of code to implement your application. Small code allows for faster development and fewer glitches.  This makes the code easier to work with and to maintain. Rails can automatically create an entire set of CRUD (Create, Retrieve, Update, and Delete) operations and views on any database table. This scaffolding gets you up and running quickly. Because Rails uses intelligent reflection to automatically map database tables to Ruby objects, your application code and running database will already contain everything Rails needs to know.

The use of Ruby on Rails is focused on simplicity and productivity; letting the computers do the work.   In a few short years, the usage of Ruby on Rails has grown rapidly.

Here are some prominent organizations that are using Ruby on Rails in the workplace:

Amazon.com
NASA
JP Morgan Chase
Yahoo
Oakley

Back in 2000, Mozilla created a non-profit organization that sponsors the Mozilla project and devotes its resources to promoting openness, innovation  and opportunity on the Internet. They do this by supporting the community of Mozilla contributors and by assisting others who are building similar opensource technologies benefiting users worldwide.

In a virtual environment, companies install software on machines at one data center and workers use inexpensive computers equipped with software that allows them to run the software remotely.

Companies save money because technicians can perform maintenance from a single location, saving them the trouble of accessing equipment sprawled across the company. The technology makes it easier for companies to move operations in a natural disaster.

Are you interested in a fast growing career in computers?

Computer science and engineering related jobs are in high demand across the country and around the world. Earning your degree in computer science can put you on track for a great career. 

Computer scientists work as theorists, researchers, or inventors. Computer science as a discipline focuses on the different methods of computation. When you earn a degree in computer science you will study theories of computer science, algorithms, basic programming languages such as C and C++, compiler design, and database management. Education requirements range from an associate degree to a doctoral degree in this field, and continuing education is required to keep up with new technologies.

Employment opportunities is this area are anticipated to grow faster than the average as businesses expand their use of technology.  There is a projected 40% growth through 2014 according to the United States Bureau of Labor Statistics.  The average salary for a computer scientist is $81,000.

Computer Training Schools 

When you go to school to become a computer repair technician, you will learn how PCs function, how to troubleshoot problems with printers, modems, and other equipment, as well as how to install software.

Many computer programming schools offer certificate programs, associates degrees and bachelor degrees in computer repair.  These will vary by school vary, but in most cases programs will offer study in PC maintenance and servicing, DOS, UNIX OS, Windows, and NT/2000.  You might also have courses in software troubleshooting and network administration.

This training will prepare you for the A+ certification test that certifies the competency of PC repair technicians. This certification is vital to employers as it says that you are a qualified computer repair technician. 

According to the U.S. Department of Labor, the average hourly wage in 2006 for computer, and office-machine technicians was $18.29. degree information coming!

Upon conducting my research I came across the actual email Linus sent to a Usenet Group back in 1991 announcing the kick off of his operating system:

From: torvalds@klaava.Helsinki.F  (Linus Benedict Torvalds)
Newsgroups: comp.os.minix
Subject: What would you like to see most in minix?
Summary: small poll for my new operating system
Message-ID: <1991Aug25.205708.9541@klaava.Helsinki.FI
Date: 25 Aug 91 20:57:08 GMT
Organization: University of Helsinki
Hello everybody out there using minix -

I’m doing a (free) operating system (just a hobby, won’t be big and
professional like gnu) for 386(486) AT clones.  This has been brewing
since april, and is starting to get ready.  I’d like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).

I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work.
This implies that I’ll get something practical within a few months, and
I’d like to know what features most people would want.  Any suggestions
are welcome, but I won’t promise I’ll implement them

               Linus (torvalds@kruuna.helsinki.fi

PS.  Yes – it’s free of any minix code, and it has a multi-threaded fs.
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that’s all I have .

Linus uploaded the first version of Linux, version 0.01 in September of 1991. Then Linux belonged to the world.

As we say, the rest is history.

The Oracle Database is a relational database management system software product released by Oracle Corporation and has become a major factor in database computing.

Oracle’s 9i OCA (Oracle Certified Associate) DBA (Database Administrator) certification is for “apprentice skill level” IT professionals. Oracle 9i OCA was introduced in late 2001, and requires no specific prerequisite. Having experience in SQL and database operations would be helpful however.   

This certification is well suited to IT personnel, with titles such as database administrator, database analyst, and database developer. The Oracle 9i OCA designation is achieved by passing several exams. You must first earn the Oracle Certified Associate (OCA) credential on your desired track (such as Oracle9i). For Oracle 9i you must then pass: Oracle9i Database Fundamentals II, and Oracle9i Database Performance Tuning.

There are continuing requirements with your Oracle certification as well.  Oracle will periodically announce requirements for recertification based on the release of new products and upgrades. You have 6 months after the announcement to re-certify.

The expertise of today’s Oracle database administrators is integral to the success of today’s complex system environments. The work of these databases requires a broad understanding of the architecture and process of the Oracle database.
