Let Google host your email :)

I’ve heard about it quite long ago from my VNOSS friends, but have just tried to do it by myself recently. Please pardon my ignorance, as usual..

If you own a domain (e.g. johndoe.com or vnfreelance.net the thingy you’re reading)  and you want to have a good email solution for it, this may be the answer.

Simply go to Google Apps, choose ‘Organizations and members’ if you want to try the free version and follow the steps to register your domains

MS SQL 2005: creating a multi-server environment

If you’re not using SQL Server for your daily job, please ignore this post.

If you come to this post after hours of Googling and cursing, this is the place for you to share.

If you wonder why I have a beginning like this, read this post which I found from Google myself.

It took me 2 man-days to finally set up a master-target server configuration on 2 instances of SQL Server 2005. Various problems along the way but I think you won’t miss it if you follow each and every of the steps below:

My Push Mail

If you don’t know what it is, read this : http://en.wikipedia.org/wiki/Push_e-mail
For more information about how it works, read this: http://www.techatplay.com/2006/10/18/how-does-direct-push-really-work/

In short, it keeps you connected with your corporate mailbox when and where you want, provided you have a DirectPush-enabled device and (you) can access the Internet with it.

Good dreams and bad dreams

There are good dreams and there are bad dreams.

One night I dreamt that I lost my heart somewhere, and was frantically running around searching for it with the empty chest. You can imagine I was more than happy the next morning to see that it was a dream and my heart is beating inside

No one, in fact, can search for his own heart.

Last night I dreamt that I could do a Union query within Cognos Framework Manager. There was a GUI interface and I just dragged Query 1 and Query 2 into the unioned Query3 . Zoom!

As you have expected, it is a dream. And as a dream it is not (yet) true. As of yesterday I could only publish Query 1 and Query 2 separately then do the union in Report Studio. Otherwise I must write the Union join in FWM and see whether it can work in ‘Database only’ processing mode.

Will get back later if reality comes any closer to the dream!

RTFM (Read the friendly manual)!

It is always right, damn right!

Until 5 minutes ago I’ve been blaming DB2 on not allowing to limit the number of rows for each SQL, which I can do in SQL Server simply by using ’select TOP nnn ‘ + blah blah blah. Or in MySQL it’s something like ’select blah blah blah’ + limit nnn

Actually in DB2 I can do it by ’select blah blah blah’ then FETCH FIRST NNN ROWS ONLY

Then who’s stupid?

And this is mentioned here http://en.wikipedia.org/wiki/Select_(SQL) which I must have read at least once!

Yeah, RTFM!

Replacing HDD on Thinkpad T43

Well well so long I haven’t been back to blogging (and I think I have good reasons for it) but this topic deserves a post anyway

My Thinkpad T43 is running clumsy after I tried some datawarehousing and BI stuffs on it. It’s good time for a HDD upgrade considering the cost for a new HDD (which is around a business dinner) and the urge to make a fresh reinstall of Windoze.

My first concern is to copy the pre-desktop partition of the OEM HDD to the new HDD and make it work with the blue ‘Access IBM’ button. I did some search on Google and came across with this article which seems to be interesting: http://tech.slupik.com/

Thinking it’s enough, I bought a Samsung 120GB disk from a retail store in Low Yat Plaza and rushed to the hotel room to begin my disk change process.

It didn’t work, simply because the post was intended for a T42 and mine is a T43 which has different config. Yeah that’s me, silly TT

Host transfer..

20061227 16h30: it comes to my mind that the existing host is about to expire, and I’ve had enough of it. Works OK inside Vietnam but horribly for visitors from outside…must do something

20061227 16h30: one of the old name comes to mind. Hostgator. Have chatted with ‘em several times…seems to be good guys. OK let’s do it.

SQL server express…

Một góc nhìn về SOA

A Primer for Service-Oriented Architecture (SOA)
By Niel Powers, Vice President of Products for Progress OpenEdge Division
Bản gốc ở đây: http://www.progress.com/

Trong lĩnh vực công nghệ người ta thường hay tìm cách mô tả và định nghĩa những phương pháp tiếp cận mới bằng cách đặc tả những khía cạnh kỹ thuật. Thế là lập tức có ngay những từ viết tắt, những chuẩn, những đặc tính nó có thể đem lại cho người đọc đủ mọi thứ trên đời, chỉ trừ khả năng hiểu được vấn đề.

Thế nên chúng ta hãy thử một cách khác: hãy bàn về SOA từ góc độ doanh nghiệp thuần túy. Yêu cầu của doanh nghiệp luôn thay đổi kéo theo nhu cầu đối với hệ thống IT cũng thay đổi và cuối cùng là các công nghệ, phương pháp và chuẩn cũng phải thay đổi theo. Cách nhìn này khả dĩ giúp chúng ta có một khái niệm chung về SOA cho dù ta đang đứng ở vị trí nào trong doanh nghiệp

Bản chất SOA chỉ đơn thuần là sự đáp ứng đối với một thách thức ngày càng lớn: đó là yêu cầu thực tế thay đổi ngày càng nhanh, đến mức những cấu trúc ứng dụng kiểu truyền thống không còn giải quyết nổi.
