About Me

Hi! My name is Buu Nguyen. I am Technology Director at QASymphony, a Bay Area startup where I lead a team developing qTrace and a few other products in stealth mode.

Before joining QASymphony, I worked at KMS Technology as their Vice President and helped build the company from 4 to 300 employees. I also taught some undergraduate courses (software architecture, J2EE enterprise development and .NET web development) at RMIT University.

When I was in Vietnam, I frequently spoke at conferences and conducted training for Microsoft. I have been a Microsoft MVP since 2009.

A polyglot programmer, I have hacked in more than a dozen languages, including Bike, a language I developed. In recent projects, I’m coding C#, CoffeeScript, TypeScript and Scala.

In my free time, I work on open-source projects (check out my CodePlex and GitHub profile if you’re interested), read books and surf Hacker News.

I can be reached at buunguyen@[remove_spam_text]gmail.com.

    Buu,

    I visit your blog every now and then when your posts get popular on dzone. I find that you always have something interesting to say. I guess you’re in Vietnam most of the time. I wish I had a chance to visit you in person when I was in Vietnam the last half of June this year. Well, next time then.

    Hi,
    I haven’t read much but I found you blog interesting. I work at CSCV too :-)
    I found that some developers wrote code just to complete their tasks. What do you think about that?

    Thưa thầy, trong các video hướng dẫn về C# 3.0 cũng như 4.0 của thầy, em thấy IDE Visual Studio có một số plugin rất hay, ví dụ khi khai báo Person person = new Person() chẳng hạn thì bên trái panel có hình “bóng điện” nháy nháy. Thầy cho em hỏi đó là plugin nào ạ??:))

    Hi Mr. Buu Nguyen
    I’m Quan, I’m learning about Java programming and having a problem with some 2D geometry algorithms, one of them is how to determine a line segment(defined by 4 coordinates: x1, y1, x2, y2) intersects a convex polygon(triangle, rectangle…), and can i use ‘line-polygon intersection algorithms’ for determining intersection between two polygons (ex: triangle-triangle, triangle-rectangle, rectangle-rectangle,…). Can you give me a fast algorithm to solve them.

    Thank you!

    Hello Buu,

    I am currently working on a project that is using your Combres tool. I am trying to accomplish something but no matter what I do I cannot get it to work. I am trying to use import for DotLess and it I do what you said in a StackOverflow answer (http://stackoverflow.com/questions/7065428/possible-to-make-several-css-files-reuse-the-same-css-variables-with-combres-and) to add DotLessCssCombineFilter and this should solve the problem. This does not seem to work and I cannot get import and combres to work together. Any way you could let me know what I am missing? Maybe you can expand on what you said in your response. I am not really a developer but would like to get this to work.

    em gặp vấn đề với unload assembly reflection, cần sự giúp đỡ của anh

    reflection in .Net 4.0 support call DLL runtime, I use System.Reflection.Assembly.LoadFile(@”D:\MyAssembly1.dll”);

    to load DLL from local location

    after using it, i want to unload(release) it, but I cannot

    @Tan: Assembly khi đã load rồi thì không thể unload. Tuy nhiên, em có thể load nó vào 1 AppDomain độc lập, sau đó unload cái AppDomain đó.

    know a few of the pictures aren’t loading correctly. I’m not sure why but I think its a
    linking issue. I’ve tried it in two different browsers and both show the same results.

    Hi,

    first I will congratulate you for writing the great library fasterflect!

    But in the actual version I has an problem.
    I can’t find the DelegateForCallStaticMethod extension method in the last version of fasterflect (version 2.1.3). Has this extension-method been removed?

    If yes, how can I create an delegate for calling a static method with fasterflect?
