Another view of the problem I try to solve

The issue:
I found that paper is essential in current business work. Having a hard-copy of a document, a copy of design, it's the most effective way for discussion, for making notes, and recording a decision. To work effectively, it's important to have a hard copy.

The Goal:
I wish that we can work smoothly without the hard copy of docs, note books.

Possible solution:
I wonder AR and computer 3D vision may bring this to reality. Virtual "hard copy" of the docs. You can spread it out over your desk, flip through it, write on it and what ever else that you can think of that you may do with a real paper. Maybe not paper air plane. Why not?
Virtual note book that you can write on. The pen can be your finger or a pen, or something that your computer treat as a pen.

Water down version: (Need to check the current tech level and might be a first step toward a better version)
Is there some window manager that can work with AR or VR eye-wears? It's might be able to simulate a huge virtual screen around the user.
Is there 3D computer vision close to the market?

Spring framework, Hibernate and MySQL Replication

Image
Laterly we have our site grown to the stage that a single mysql server will not able to do the job anymore. That's something we realy like to see. The CPU usage had reached more then 90% at peak traffic time. MySQL even crashed a couple time when we were running an early version. 5.0.x. Don't remember what it was exactly. But when we upgrade to 5.0.24, it stopped crashing. It was also unacceptablely slow under the heavy loads. We need some heavy duty database solution. I have read a couple articals about mysql cluster. So my first thought is cluster. But when we ask our hosting company to set up a MySQL cluster, they suggested replication instead. Sometimes you just could not judge things by their name. Have run into the word "replication" a couple times in the mysql ref book. I miss judged the replication function. My sql does not like some other databases, this replication is real-time replication. To set up a master/slave replication system up is really a straight

the Art of Kindling a Light in the darkness of mere being

Playboy interview Stanley Kubrick published 1968 Sept Playboy:  Thanks to those special effects, 2001 is undoubtedly the most graphic depiction of space flight in the history of films — and yet you have admitted that you yourself refuse to fly, even in a commercial jet liner. Why? Kubrick : I suppose it comes down to a rather awesome awareness of mortality. Our ability, unlike the other animals, to conceptualize our own end creates tremendous psychic strains within us; whether we like to admit it or not, in each man’s chest a tiny ferret of fear at this ultimate knowledge gnaws away at his ego and his sense of purpose. We’re fortunate, in a way, that our body, and the fulfillment of its needs and functions, plays such an imperative role in our lives; this physical shell creates a buffer between us and the mind-paralyzing realization that only a few years of existence separate birth from death. If man really sat back and thought about his impending termination, and his terrifying ins

Exposed Domain Object implemented with Spring Aspect Transaction Control + AspectJ

Image
This application was designed and implemented as my first web app following the DDD principles. There are some interesting issues to solve. I had the domain models exposed to the presentation layer. No facade!??? Yeeeeaah, but not exactly. I did not see the similar design at other places yet. Which has no facade in front of domain models, no facade between presentation and business layers. I can imagine the reaction from people who are so used to facade. Spring+AspectJ allow you have this design. Using domain object that has the supporting DAO injected and letting "spring's annotation transaction aspect" handles the transaction. It can work. Although, using Spring+AspectJ can implement this design, it doesn't necessarily mean this design is good for all applications. An evaluation needs to be done. Here are the pros and cons . Pros: Faster development. It accelerates the development. No Facade for the exposed domain model. When a domain object is a natural entry point
