Last update: January 15, 2022

If you are doing frontend development nowadays, you may have heard about ReactJS or may be actively using it in your projects. Introduced to the public five years ago, React has transformed into a library of choice for a lot of frontend developers that is easily certified by the enormous stars at its Github page (more than 100,000 stars). React was relicensed into MIT license almost a year ago, which only catapulted its popularity into a new high. The MIT license is a more commercial friendly license compared to the BSD + patents license that was previously used by React.

Creating a frontend project is easy with the help of scaffolding tools and boilerplates. Among the available choices is create-react-app, a React bootstrapping utility that takes care the laborious tasks of setting up a React project without much intervention about how the project should be structured. Given this nature, create-react-app is less assumed a boilerplate and more of a toolkit. Continue reading →

This is the first article of the Maven tutorial series for beginners. For those interested in building their Java projects on top of Maven structure, the articles in the series may help.

Preface

For Java developers, Maven is not an alien word. It is much known as a very powerful tool used to build and manage Java projects with varying size and complexities. Aside from being powerful, it is also pervasive, which is exhibited by substantial presence across projects and entities. It is used by individual developers whose projects are being shared in the public repositories to big enterprises with a walled garden protecting the codebase.

This article is targeted to Maven first-timers who are fiddling with Maven on Windows and are in need of guide to installing, configuring, and using Maven for their next Java project. Even though Maven can work across different versions of Windows, the articles and reference images were created in the environment as specified below:

VMWare Customer Day 2010 Korea: Cloud Computing Adoption in Enterprises and vSphere 4.1

Leave a reply

On Friday, September 10th, I attended VMWare Customer Day 2010 Korea, which was held at COEX Intercontinental Hotel, Seoul. Even though it has been a while past the event, I would like to share some notes worth sharing, combined with my personal thought about substantial content found in the talks I listened to during the event.

As the event title suggests, the talks mostly covered introductory concept about cloud computing and virtualization as well as some promotional materials about VMWare products. This is coherent with the majority of the audience who came from the enterprises: IT staffs, ISV representatives, and company delegates. Three sessions were arranged for the whole event. The first session was a talk from Mike Sumner, the VMWare Asia Pacific SE Director. He talked about customer journey to IT as a service by riding the cloud and harnessing virtualization. Second talk about VMWare case studies was presented by Lee Mun-hyong, the Director of Channel and Alliance, VMWare Korea. The last session was delivered by Lee-Hyo, the head of VMWare Korea. He explained about vSphere 4.1 especially the new features in the release. The second and third session were presented in Korean so I only grabbed the general understanding and did not really grasp the details.

In his presentation, Mike talked about cloud computing as an emerging trend in the enterprise. He also explained key drivers and phases toward its adoption in the enterprises and an era of IT as a service powered by the cloud. He started with listing several IT challenges in the enterprise environment. The challenges he mentioned include the necessity to deliver more business value, the ability to move faster and stay ahead of the competitors, the competency to maintain secure and compliant environment, and the capability of maintaining a stable system. Legacy IT business model relies on infrastructure ownership and dedicated IT force. With the introduction of the cloud in the enterprise, CIO may consider the transformation from a pay-in-advanced system into a cloud-based, pay-as-you-go system.

Fighting Against Spam Comments, an Endless War for Blog Owners

8 Replies

I have been experimenting with comment settings in this blog to observe how willing spammers leave undesirable footprints aka spam comments on the blogs. Someone might have said that spamming is as pervasive as the web itself and it grows as the web evolves and reaches more audience. Still, having a hindsight experience in analyzing spam comment trending and behavior will be beneficial for me and also other website owners and bloggers especially when they are considering a loose commenting policy on their website.

Interaction in social web sites

As the web evolves to be more social, we can also observe higher level of interactivity on the web. Not only quicker page load, better content presentation, and improved system interface is interactivity characterized with, it also includes a simplified way of interaction among the website or web application users. In a bigger picture, interactivity encompasses user-application interaction and user-user interaction. If we talk about user-user interaction, we may think about creating such a user friendly platform for them to interact and communicate. Specific to blogging, user-user interaction can take form as commenting on the posts and also other user’s comment.

Now, here the question comes. If we can provide our users a friendly interface for interaction even for first-timers, can we expect for more quality interaction? And my personal answer to this is it depends on how good we are in implementing the website growth strategy. The first thing on which attention should be put thoroughly is the content. “Content is the king” is an undisclosed truth that tops the strategies towards website growth. I have been analyzing the growth of this technology blog by comparing number of posts in a certain month with the incoming traffic (user visits) for the corresponding month. I found two cases where traffic was higher than the average. The first case is the month with quality post(s) that drew users’ attention regardless of the total number of posts in that month. For the second case, it is the month with more posts, regardless of the quality, compared to the average monthly number of posts.

Useful Zend Framework Resources for Developers, Users, and Enthusiasts

3 Replies

As I heard that Zend Framework 2.0 is on the way to the public release, I became curious to know how the framework had been evolving during the recent releases. I started to fiddle with Zend Framework again but also realized that I should update my comprehension and knowledge about the framework. It has been a while since I wrote a complex ZF-based application for the last time. I feel it is necessary to collect more information about framework; manual, technical notes, tutorials, case studies, people, communities, and so forth so that I can upgrade my knowledge and get back on the track again. I found a good compilation by Robert Basic that actually covers almost all things in my list. Still, I consider that providing an alternative list is far from being counterproductive. Instead, the information redundancy can be good especially when the lists complement each other.

Below, I categorize useful resources one can use to learn about Zend Framework. If you have suggestions about other resources to add, feel free to drop a comment and I will add it into the list.
