Brainstorming: Do you like Sports? Join Us!

Do you enjoy your life in Hawaii?? I have been living in Hawaii for 5 years and since I came here from Korea, I met many good and nice people. As many people say, sharing interests is one of best way to communicate with others. So some of my friends and I started to make a sports club in Hawaii. The club grouped by 12 people, who are not only students but also others. We play golf, tennis, badminton, and so on. If new member brings a new sport, we enjoy to learn and play together, and if new members want to have any lessons, it would be free.

The club is capable of:
  • making connection between people in various social positions
  • teaching and learning new sports
  • getting help from other member
  • creating maximum joy with minimum outcome
The club offers benefits of:
  • Golf: Automatic Tee time reservation service and Free Lesson
  • Tennis: Free Lesson
  • Badminton: Free Lesson
  • Bowling: Free Lesson

Brainstorming: Non-profit Organization- 'BM foundations'

The purpose of BM Foundation is to enhance healthcare and reduce poverty globally and to expand educational opportunities and information technology in America.
The BM Foundation follows the belief that every life has equal value. The Foundation works to help all people lead healthy, productive lives. In developing countries, the Foundation focuses on improving people's health and giving them the chance to lift themselves out of hunger and extreme poverty. In the United States, the Foundation seeks to ensure that all people have access to the opportunities they need to succeed in both school and life.

System Capabilities
  • One standard process across the foundation to develop grants and contracts with a charitable purpose.
  • Co-defining, at the outset, what success looks like, and aligning with our potential grantees and partners on the most important and measurable outcomes
  • Scalable tools that can be tailored according to the complexity of the investment.

Brainstorming: Vision system captures the perfect swing1

Problem Description
Many golfers in the world always wanted to have perfect swing in golf. They are curious that how they can swing like Tiger Woods who is no.1 PGA golfer in the world. Mastering the perfect swing is a matter of practice and patient training. So they go to driving range for hitting many balls until they become satisfied. Some people have lessons from teaching professionals, and they spend more than $300 per month. Most people agree that getting teaching pro would work to fix swing, but some people curious that how the human vision is more accurate than computing system.  Professional golfers have been using video recordings for some time to analyze their swing in detail and improve it. With the system "Swing & See" developed by R&D Vision of France, amateurs now have access to this technology and can benefit from a powerful analysis tool on the golf course in their neighborhood. The system relies on Pike F-032B cameras from Allied Vision Technologies to capture and precisely document each phase of the swing movement. It has, of course, always been possible for any golfer to have themselves filmed by a friend with a camcorder to analyze their mistakes. Although this method may provide some help, it offers limited analysis capabilities: The image quality depends on the quality of the camera used and the skills of the person operating it. Furthermore, recordings cannot be viewed properly on site without an appropriate display. They may include movement artifacts and show the action only from one view angle.

System Capabilities
R&D Vision, a R&D company that specializes in advanced imaging solutions, has developed the "Swing & See" tutorial tool for its client V2S. The system consists of an interactive terminal that houses the control unit and image processing combined with two AVT Pike digital cameras and a color touch-screen display. The whole set is permanently installed on the golf practice tee and is weather-proof for outdoor installation.
The movement of the swinging golfer is captured by the two cameras simultaneously at 200 frames/s. The cameras are positioned with a 90-degree angle to each other in order to record the action simultaneously from the front and the side. The high frame rate and short shutter time (<500 ┬Ás) enable sharp images of every single step of the movement. The start of recording is automatically and simultaneously triggered by image-processing software able to identify the position of the ball. Thus, the whole swing process is precisely captured from both view angles.

As soon as a shot has been recorded, the player can watch his or her swing on the display. A didactic tool allows slow motion control for an image-by-image replay in order to detect the slightest imperfection. Graphic markings can be added on the picture to help assess the swing motion; comparison mode compares the player's performance with that of a professional instructor (or one's earlier motion) stored in the system memory.
After the training, the golfer can save all data (video file, assessment of the swing, speed of the ball, etc.) on a digital storage device such as a USB drive or memory card. That way, he can archive his performance at home on his PC to follow up on his progress or further analyze the video recording at home with companion software available for download on the web site of the service provider.

What Is RUbY?~!

What is Ruby?
Ruby is a programming language. You'll often see a number of buzzwords accompany the "programming language" phrase, but those will often impose preconceived notions of what those words should mean on to Ruby itself. Above all else, Ruby is a programming language.

The Good

Ruby is an object oriented programming language. Everything in Ruby is an object, so Ruby is an object oriented language in the purest sense of the word. It isn't like C++ or C# where you have object types and value types, or even Java where most things are objects and a few native types must be "boxed" in order to be treated like objects, everything in Ruby is an object.
Ruby is a dynamic programming language. Many programming languages have a notion of "compile time" and "run time." Those are two different universes, the compiler knows completely different things than the runtime environment. Ruby, on the other hand, makes no distinction. Everything in Ruby is decided on at the last conceivable moment. If you want to call the method called foo on the object called bar, Ruby not only has to look up where this method lives, but it has to look up where the object bar lives. This is in contrast with languages like C, where the compiler knows the exact address and type of objects as well as what methods it has and their addresses.
Ruby is a programming language for the world wide web. While not strictly true, a number of libraries such as Sinatra and Rails make Ruby an ideal language for programming web applications. Many people have only ever heard of Ruby in the context of Ruby on Rails, Rails has been Ruby's "killer app" for quite a long time now. Ruby also makes it quite easy to act as a web client for writing scrapers, spiders and many other non-browser web denizens.
Ruby is a scripting language. The term "scripting language" is very often misused or misinterpreted. Many people take it to mean "interpreted" or "non-compiled" language. While Ruby certainly is this, it is also a proper scripting language, meaning it can be embedded in other programs and be used to control them. A perfect example of this is Google Sketchup, Ruby is used as a plugin interface to programmatically control both the program and the 3D models drawn by the program. While there are some other easier scripting languages to embed, Ruby is still a solid and full-featured choice for a scripting language.
Ruby is free. Ruby doesn't cost anything to download or use for any purpose. Not only is the official Ruby interpreter free, but there are several other free Ruby interpreters for various platforms. There are no tricks, it's not a trial version, Ruby is free. Ruby is also free software, meaning any user of Ruby is free to see and modify the source code according to their needs.

The Bad

These were all descriptive and good things about Ruby, how about some of the uglier parts?
Ruby is slow. Compiled code from languages like C++ or C# absolutely smoke Ruby. Even other languages in the same class as Ruby such as Python or Perl can often be much faster than Ruby. However, the "Ruby is slow" adage comes from a time when Ruby was really, really slow. Prior to Ruby 1.9.x, Ruby was significantly slower. The current version as of this writing, Ruby 1.9.3, is quite fast compared to previous versions. So take this adage with a grain of salt and don't assume Ruby will be too slow for your needs, run some benchmarks first..
Ruby is an object oriented programming language, but only an object oriented programming language. If you don't like object oriented programming, it might be wise to stay clear of Ruby. Some other languages, such as Perl, try to be accommodating to all programmers. If you don't like OO programming, that's OK, there's more than one way to do it. But not Ruby, it's more or less OO or nothing.
Ruby is trendy. Trendy programming languages come and go. Ruby's popularity skyrocketed around 2005 when all of the Ruby on Rails fervor was happening. It was seen as a "trendy" programming language by many, and wouldn't stay popular for long. While we don't know if Ruby will still be around 10 years from now, the amount of Ruby code being written for Rubygems and on Github certain suggests it's genuinely popular and will be around for quite some time.
Ruby is not as popular as other languages. There are Ruby jobs out there, plenty of them. But there are many more PHP and Java jobs out there. If you're learning a language to find a job, Ruby might not be the best choice. However, at least in this author's opinion, you'll have a lot more fun with Ruby than any of the other choices.
