OpenStack, new cloud platform by Rackspace now reveals the feature. (The official site is here) Cloud may be a lucrative market and the platform would be diversified. And service providers already support a few platforms like Windows Azure and Ubuntu for cloud. And it is the time for him to ask: "Why OpenStack?" or "Why open source platform?" Unfortunately, I couldn't find any answer yet.

Well, anyway this is somewhat risky though the market is truely competitive as it knocks the door of the unauthorized. I agree that it is a big news, yet the market is not that stable.

One thing OpenStack team should keep in mind is that the result of the war would depend on not what he serves but WHY he does. Even though he'd rather not ignore the technical issue, checking the vision of the project before the rush is important. Now it's show-time.

On the other hand, overly going far away from the reality might be a problem. Many artists and creators have been in life with highly positioned view. Their activity effects largely and sometimes constructs the innovative system. However, some of the masterpiece had jeopardized the authority of politicians or soldiers. There was a gigantic ripple from the Copernican theory which argued that the Sun is fixed and the Earth revolves on it. Even though the theory was proven as a truth, it is certain that it striked the society.

The problem is that, some people don't want change. Furthermore, most people don't like revolution, a colossal transformation. That is the dilemma. Nowadays people are too busy to take care of the change, though, putting the context in perspective gives a possibility to be better off. It is the magic of life I think. While analysts see the fact and conclude it with the objective ground, artists see through the essence and conclude it with vagary of the context. In conclusion, the artist thing gets us to adopt dynamic and brilliant life.

Primarilly, Apple's position is in design and CONVENIENCE of his consumers. However, he missed a subtle part of service which is strongly related to the convenience. Convenience is judged by customers, not by the product itself. Though Apple's A/S policy is not that good, he sells lots of iPhones and iPads because the buyers believe Apple as a representitive of convenience and evolution. But in spite of dysfunctional antenna of iPhone 4, Apple acts like they have no idea to fix the problem. I think it's far from convenience (and even gets people feel a little upset).

Google has a different kind of problem. I heard that Google wants to get into Game industry. I hope not because the position of Google is not entertaining. It is similar to the case of IBM that the market extention brought confusion. In my humble opinion, Google should not try any outranged bombardment for it would kill anybody including himself.

Big runners may miss something. The focal point is that they should acknowledge the fact and deal with the problem quickly and precisely. Showing mistake is not shameful action but the ignorance of them is the shameful.

Validation of Web Standard (W3C Validation)
The main reason of this phase is that many browser vendors have made their programs so differently. Keeping web standard may help your service shown identically regardless of browser environment. W3C, who enacts the web standard offers a service to validate online. (http://validator.w3.org) Insert your site address and click Check button to conduct validation. If you meet some errors or warnings, then you'd better remove them all.

Optimization
Optimization is important to improve the performance of the service. According to the statistics from Amazon.com, 0.1 second speed-up brings 1% revenue increment. There are many subjects about the method so you can research for them. Here is a list of optimizing issues.

- Locating inline script and stylesheet(CSS) properly.
- Deferred script.
- Gzip compression.
- How CSS selector operates in browser.
- Optimization of images (GIF, JPEG, PNG, etc)

Security Manners
It is essential to sanitize user's input. You'll get a big trouble by hackers who targets at the core information in your site unless missing security managing process. That is, the personal data and information could be divulged or manipulated. The range of security is broad but you can see the following issues primarily.

- XSS (Cross-site script) attack.
- SQL injection.
- Intercepting user session.
- Exploiting vulnerabilities of browser.

How great leaders inspire action (TED)
It's a wonderful talk about leadership. Starting with WHY-thinking is enough to inspire people including managers, employees and customers. Beyond the archetype of standard manager, leaders may innovate business and operation while the colleagues willingly participate in their journey.

Commonly, feeling depressed or frustration is regarded as negative part of life while progression, leadership and self-esteem as positive. I think both feelings are essential in life as though the forest composes of verdantly green and brown with blue-colored river flowing through the path. The problem is that flucturating condition is normal but the recognition and repercussion upon the fact are differ from perspectives of people. That is, the discrepancy between reality and thought has the life intricated.

How can we make the life better? Harmony would be the answer. White-color only and black-color only drawing obligate the life to monotonize and to demotivate people to live. Prismatic dream matters because it will encourage the artists to paint their portrait and the world with fantasy.

Actually I was worried about the World Cup because I heard that African counties have weak security. There have been many murders even in a day. But now, it is truely a nice chance to clear up such kind of notoriety I think. And I hope that South Africa and other African countries would get an opportunity to think about their nations with patriotic mind.

The ball is round. All participants have equal value each, and so the nations. I will enjoy the rest of the game which might make things in the globe better.

What is Security Management? It is a really hard-hitting question for security managers. Sadly many people involved in security management cannot answer it clearly. Intuitive approach is not bad, but getting the answer known would be a great help to focus on what and how they should do for increasing security performance.

The performance of security cannot be estimated by numerical values, though, I suggest an easy equation to imply the elements of security. Here is the one.

Risk = Value * (Threat * Vulnerabilities / Countermeasures)

Companies consider Risk so as to minimize the loss from it. Fully understanding of each factors in this formula would lead you to know about the risk and then apparently define the role of security manager.

The first is Value which means the valuable things separated into 3 categories: monetary value, future value and secrets. If there is no value, there is no risk.

And the next one is Threat, the possible threats which can give you damage regardless of their intention, for example, natural disasters like earthquake, hackers, etc. These two elements cannot be reduced by security plan but the following things (Vulnerability and Countermeasures) are controllable and so more focused when thinking of the role of security manager.

Vulnerability is a kind of hole which can be exploited and hackers harness them in software to exploit users to do what they intend to. And Countermeasures are the methods to prevent the accident. Countermeasures could be firewall, anti-virus software and so forth. Security managers should make their plans focusing on those two elements. They need to search for possible vulnerabilities and to seek for countermeasures against them.

In conclusion, the role of security manager is not to MINIMIZE the risk but to OPTIMIZE it. Assigned budgets would be limited because most senior managers and CEOs don't like to invest into such an invisible matter. Security manager can offer the report of vulnerabilities and show how he or she can reduce the damage from any disasters, then the security plan would be going through the right path without profligate spending.

To build the system, you should get the libraries required. And Android site suggests the following command to install all of them.

$ sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

Everything would be okay except.. sun-java5-jdk. The package is deprecated and is now unavailable. Then what can we do instead? Open JDK is the answer. You can do the following to get it.

$ sudo apt-get install openjdk-6-jdk ant
$ sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

You may notice that the version of Java is 6 and Google warns that Java 6 is not supported in Android because of incompatibilities with @Override. However, there's no problem to get the source and build the system. Before getting the code, you need to set for repo.

$ sudo curl http://android.git.kernel.org/repo -o /usr/local/bin/repo
$ chmod a+x ~/usr/local/bin/repo

You're set the environment and now is the time to get the source. Go to the location where you want to get the whole source and give the commands.

$ repo init -u git://android.git.kernel.org/platform/manifest.git
$ repo sync

If you encounter the message "command not found" then you can do it with the following commands:

$ sudo sh /usr/local/bin/repo init -u git://android.git.kernel.org/platform/manifest.git
$ sudo sh /usr/local/bin/repo sync

It will take much time to get the code even though the line is fast as the project itself is really huge. After the long waiting, you will find that the checkout process has been ended. The next thing to do is MAKE to build the project. But you will meet a message that the Java version is not correct and the build process fails. Then you can modify the build/core/main.mk file to change the text "1.5" to "1.6".

One more thing to do. Ubuntu 10.04 has tweaked a little and you should install additional features like the follow:

$ sudo apt-get install gcc-multilib g++-multilib

This is the finally stage. You can build it clearly with MAKE command. But remember that it may cost a lot of time even more than to get source codes. Anyway, I succeeded to do all these kinds!

I define this kind of state as the immersion. Generally, someone who is in immersion may not do other things properly. However, he or she would make a great result with it and this is the power of immersion.

Then we can ask that the cognition is always bad. Nope. The cognition is essential and the timing does matter. It is differ from people by people and it can be attained from real practice.

But remember that you might fail to get into the state soon after perceiving the timing. It seems like the circumstance that we are not able to start to sleep easily when we focus on to get a sleep. The immersion comes silently without cognition like the sleeping matter.

Then what is the meaning of the cognition? It is to arrange the result of immersion. This process is truely important and the period of time to concentrate on something would be shortened without it. Broken window theory will help you to understand. If the window of a house is broken, it can be more damaged by others. Absence of cognition breaks the window.

We need to think and choose what we should do first to get into the cycle. Normally cognition-first-immersion-last would be better. It will lead us to know what should we dip into.

This is not a kind of theory but reality and life. Anyway, the process operates when we do not notice it and in that manner, this posting could be a meta-cognition.

Let's think about the rule which benefits the workers like an incentive. That would motivate the workers to achieve their goal (or not). Then, how about removing the incentive? Demotivation would be the crucial return. In perspective of executives, incentive is not must-be matter but is just a tool for high-performance. This kind distinct of view on rules delivers collision sometimes.

Beneficial rules would be greeted. On the other hand, these rules cannot be ceased easily because of the effect I wrote in the middle. It does not mean that incentive-like useful rules should be eliminated. Rule-maker should be considerable for both the positive-side and the negative-side when making new rule. I'd summarize the methodology here to check out before proclaiming the rule in public.

1. List the advantages of the rule (score it from -10 to 10).
2. List the disadvantages (score it from -10 to 10) when it is suspended .
3. Let's set advantages as A = { a1, a2, ..., an } and disadvantages as D = { d1, d2, ..., dn }.
4. Let's set the weight of advantages and disadvantages as W = { w1, w2, ..., wn }.
5. Calculate the total effect of advantage and disadvantage.
   That is, Ea = (A*W) / W, Ed = (D*W) / W.
6. Let P be a period of day which the effect lasts.
7. Then, check out that Ea > Ed / log(10, P).

Then setting an example would help to understand. Let's think about INCENTIVE again. Here are the lists of advantages and disadvantages with weight.

• It will motivate people to work hard. (advantage 8, weight 6)
• It will raise the loyalty to the company. (advantage 2, weight 5)
• The expense would be increased. (advantage -4, weight 2)
• It will demotivate people if incentive has gone. (disadvantage 9, weight 6)
• They will think that the company is in a hard time and may lose their loyalty. (disadvantage 5, weight 5)
• The expense would be decreased. (disadvantage -4, weight 2)

Suppose that the incentive would affect people for 3 months. Then P = 90. Finally, the following is the result.

Ea = (a1*w1 + a2*w2 + a3*w3) / (w1 + w2 + w3) = (8*6 + 2*5 + (-4)*2) / 13 = 3.84
Ed = (d1*w1 + d2*w2 + d3*w3)/ (w1 + w2 + w3) = (9*6 + 5*5 + (-4)*2) / 13 = 5.46
Ea is bigger than Ed / log(10, P) = 5.46 / 1.95 = 2.8.
Then, this incentive should not be deprecated.

1. Live news channel
It is a kind of evolution! I really love it. I always try to read articles every time when I do nothing. That helps me to easily understand social trends and issues like a cyberattack on social networking site or the recession in Greece recently. And it leads me to think how to catch the flow on earth. Although RSS feed is also available, it is not enough for most media and news companies do not open their whole contents in RSS whereas smartphone media opens in detail.

2. Social networking
Renowned social networking sites like Facebook and Twitter are supported. And it's easy to share picture and video as well as text message with smartphone-social-networking application. Most of all, I could get some thoughts and opinions on an issue from others. That's really impressive matter.

3. Weather casting
Oh, today's weather casting system is terrible. So weather casting app in smartphone does give a great help indeed. The weather is so fickle that forecaster may not tell us the weather accurately. For example, I saw an article yesterday that there would be rainy today but now, it's not raining but sunny outside. That's why I bring my phone and check the forecasting frequently.

4. Managing schedule with to-do list
Today's life is complicated. Lots of things to do with scantiness of time. To-do list is, then, a great solution. I write everything to do in that day on the list and check out after getting things done. It is a kind of reminder that I never forget what I should do that day.

And what else is able to do with smartphone? Some guys play games, listen to music, watch movie, whatsoever. Because I do not enjoy playing game or something they were not emphasized, but those are really manner in smartphone users. And managing finance and stocks would be a great use-case. Anyway, it is certain that smartphone technology changes in everything including life style. That's awesome.

The most impressive change in HTML5 is Canvas element with drawing tool. This allows developers to represent their creativity with more effective and aesthetic design. One more, offline storage database support is a brilliant feature. It will alleviate the traffic through server machine and speed up the web experience by delegating tasks which manipulate insignificant personal information to client-side. Furthermore, enhancement on dealing media contents like audio, image and video is great. Amazing achievement!

Otherwise, there are some deprecated features as well. Some tags would be removed: strike, center, applet, etc but no problem because most of them are in the area of style-sheet rather than tag element and are able to be represented in different way with CSS(Cascading Style-Sheet).

Steve Jobs' remark against Abode Flash increased interest upon HTML5. This is a kind of trend that Microsoft IE9 will strongly support it and the other browsers would go through the same way. And I think it would be quite good for web developers to read HTML5 specification document to understand the future format.

Do you think that the refactoring process can be deferred while a thought that the quickness of development is the most crucial matter in business prevails? And if you answered YES to the question, are you sure that you never lose anything or less than another choice from your decision?

Considering that human brain has its limit, in the other words, memory is volatile. It can easily go away. And most projects are complex far enough to be lost in the mid. Then someone might say that using mnemonics like post-it would help to recollect the factors.

Now it's time to think about backlogs because it's strongly related to motivation. As the time goes by, the task becomes loose and slack. For example, suppose that you have a homework for class and you procrastinate it until a day before due date. Now you should do it but may feel troublesome for you lose your mind. That is the same as to the project. Deferred process would not be getting done clearly losing the motivation unless other incentives are given. It is a kind of waste!

Refactoring right after the development is truely important. Though it may take some time and seems wasteful, the project manager should cover the nuts and bolts.

People matter is one of the most important things on earth, I mean, the relationship. The main stream flows on the humane river nonetheless there are competitions and quarrels. However humanity is usually underestimated in business world. Why are people crazy about Steve Jobs? Is it because of his career or special ability? I don't think that's all about him. There's something different in renowned and honored people and brands.

Business is basically about people. Companies try to move and lead people into their territory. And that is a great issue for it is a big deal to get attention from them in spite of their saying about customer-based marketing. Actually it is not that kind of what about people, but is really about money and product.

Entrepreneurs need to be familiar with people. Creativity does not come from loneliness. What would be the matter people crave? They can be easily attracted by a tipping point which seems delivering incredible edges in their life. After that, the brand power would be immense and no other competitors can come up with the overthrowing trigger unless the power brand makes any mistake.

Traditional methods for business analysis are not the absolute rules in this world. People change, especially in their mind. Humanity has made new trend of people-oriented stuffs so that it could open a new market. That is the way the cookie crumbles.
