Hi Buu,
I’d like to have direct conversation with you. I have just visited your blog just now, and I have quite same experience about interviewing stuff. I am also passionate with new technology stuff, esp. in .NET stuff. Hope we can exchange knowledge more in the future.
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.
Thanks for your nice words, Kevin. You’re right, I live in Vietnam most of the time. It would be nice to know you in person when you come to Vietnam next time. My email address is buunguyen at gmail dot com, let’s get in touch some time.

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??:))
@Tung: Cione.com already uploaded all video
@Hiep: I used Resharper
Cảm ơn thầy. Em đã tìm thấy. Chúc thầy mạnh khỏe và công tác tốt!
anh ơi có thể share mail của anh cho em được không ạ ?:D chúc anh mạnh khỏe công tác tốt !
@Nguyen Tan Tran Minh Khang: I don’t mind constructive criticism, but personal insult without any justification is just not acceptable in my blog. Your comment is deleted. If you don’t like what I have to share in my blog, just stay away from it — or post only constructive comments. Thank you.
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.
