DB Designer 4

2006-07-29T19:13:00.000+08:00

It has been a long time for me to look for a free (better if open source), user friendly and powerful ERD editor. Most of the foundings are trial version, limited version, non-open source, or not so user friendly.

But this week, it seems God wants to give me a gift - DB Designer 4, which is an open source, user friend and powerful DB designing tool. It support connections to various data sources, e.g. MySQL, MSSQL, Oracle and ODBC, execution of queries, reverse engineering on db design, forward engineering by applying the change in db design or generating SQL script. You're also allowed to export the diagram in to PNG or BMP, which would be useful for documentation while some other tool doesn't export any graphics...

StarUML

2006-07-29T19:06:00.000+08:00

Half year ago, I found this tool very useful for system design and documentation. Six months later, I still think so. StarUML is a free CASE tool for OO Methodology, supporting UML, MDA, and both forward and backward engineering. The tool is planned to support round-trip engineering, which I'm interested in very much. I hope the tool can be continued with its development and we can see the power of round-trip engineering at the days.

My recent thought

2006-07-06T01:19:00.000+08:00

Recently, I thought of a system framework to allow us to develop software in the same way as how chemical factory works. It will be nice if I can implement the framework, and then show you the interesting idea. Hope it won't be too late for you.

Ten Essential Tools: Visual Studio Add-Ins Every Developer Should Download Now -- MSDN Magazine, December 2005

I have just figure out a new article in MSDN magazine on add-ins for Visual Studio. Those add-ins cover areas like testing, documentation, Visual Studio usability, Web Services development and cache monitoring. I am not sure if these are useful, since I haven't read through it in detail yet. But the 10 Must-Have tools introduced by the author last year are quite helpful. Enjoy.

Ting-hao Yang's ASP.NET blog : Cross page navigation techniques in ASP.NET 1.x and 2.0

If you found the loading speed of your pages is slow, you would probably need to do some performance tuning on those pages. You may most likely think that the database query is slow, the page computation is too complicated, or the page size is too large. However, it may also be the case for long client-server round trip time (propagation delay). Here is a blog post from Yang on the details of page navigation scenerio. It may give you ideas on how to fine tune the loading time of your pages.

I don't know when will I need to work on some migration project from dotNet 1.1 to dotNet 2.0. But I do think this will happen some days later, and this tutorial will be helpful.

To lead, or to be led?

2005-12-15T15:30:00.000+08:00

It's just a very simple question. To lead, or to be led? I think most of the people thought of times that they're in the leading position. However, how many people reach there? How to get there? I don't have a concret idea. But standing behind someone and tracking their path obviously doesn't work.

Be more active, or even proactive.

Ken's Goodies Blog

2005-12-09T16:41:00.000+08:00

I'm not sure how many of you recognise that I've established a new blog, named Ken's Goodies Blog, for new product alert (or may be there's nobody reading this blog). It seems that the new blog is not very popular, perphaps it's because I've not put much effort in promoting it. I think I need to promote the blog in more public channels. Let's see what will the situation be in the early January.

Vodafone is leaving, but who's next?

2005-11-29T10:24:00.000+08:00

As reported, the loge of some high-tech companies may be on Mancehster United shirts next year. What will that be? Google? IBM? Or Yahoo? I think I'll then buy a new MU shirt the coming summer.

Create a simple file transfer Web service with .NET - Techguides - ZDNet Asia

2005-11-22T09:07:00.000+08:00

This situation is really interesting. "Creating a file transfer Web Service" is the topic of a girl's final year project last year. She also won in the Imagine Cup by Microsoft with that project. My friends lost in that competition and argue that the topic is too simple and not useful. Well, yes, it's simple to implement. But perhaps they're on the wrong track. In that competition, as shown in the name, creativity seems to mean everything.

AJAX.NET is great except that it can only apply on pages but user controls. Fortunately, there're guys trying to make things done. This Code Project article shows you how to make the user control more integrated with AJAX.

Vincent Cheung: Alarm clocks are bad. How to wake up and feel better.

2005-11-04T16:43:00.000+08:00

Well, this is something I've been doing for several years. Since I like the radio programs in the morning, I normally schedule the radio to turn on every morning, before I actually wake up. I don't know whether this method work, but I think this method really remind me of what the time is, since there will be time and weather report every 30 minutes.
