Một phút để bắt đầu sữ dụng Python

Hôm nay tôi mới download được Unikey, và quyết định viết bài này bằng tiếng Việt. Lý do đơn giản là vì đã có quá nhiều bài viết bằng Tiếng Anh rồi

Một phút bắt đầu:
- Vào website: http://www.python.org/download/, và download gói cài đặt cho Windows của bạn

- Tạo một file text với nội dung (hello.py):
print "Hello World!"

- Mở Python Shell lên và open file (hello.py) lên, một cửa sổ soạn thảo file sẽ xuất hiện

- Trên cửa sổ soạn thảo file, chọn Run\Run Module (hoặc F5)

- Kiểm tra lại cửa sổ Python Shell, bạn sẽ thấy "Hello World!" xuất hiện


Vậy là bạn có thể bắt đầu tập tành viết chương trình Python cho chính bạn rồi đó


Hy vọng mình sẽ có thời gian viết thêm nhiều về Python, những thư viện của nó, tiện ích, ích lợi, v.v.

FreeNAS: another option for clustering environment

If you ever try to install the clustering environment like Exchange, MSSQL, you will fight with the problem of installing quorum disk. And the problem going bad if your server doesn't work well with NAS (HBA, etc. compatibility issues)

Long time ago, freeNAS was born, along with him was openfiler, etc. these are the simulation for NAS that was shipped with iSCSI, and many other protocols like: FTP, Samba, CIFS, etc. and a Web-based administration tool. And to make more convenient, they was shipped with VMware appliance as well... cool !

And you don't have to invest any NAS device, you just download the ISO (Live CD) or the VMware appliance of FreeNAS, turn it on, configure it! and you will have a NAS device that working through the iSCSI protocol

The remain, is to download iSCSI initiator (Microsoft provides one), and free on many Linux distribution. Configure it to work with your new NAS. You can map 1 iSCSI disk (on your freeNAS) to as much server as you want... you have your own Quorum disk

It works for both Windows, Linux as well. Beside that, freeNAS has many interesting features like: authentication through Active Directory, work as file server, scheduling for backing up, it is built on FreeBSD

Good luck!

VirtualBox: another Virtualization host software, it is open source

I did many investigation on many virtualization software, and VMware is the best to me, at least up to now

VirtualBox, through the website, what it says is so impressive, and it is open-source as well

I will try to use it, and report the comparision later
