Ever wonder how to write easy validation for your form with Jquery? I’ve been using quite a few but none can compete with Validity, it’s a nice little javascripts snippet that can handle most of our needs for client validation. And the syntax is beautiful, too, just have a look

I have Hamachi installed on Jaunty successfully by following this article, but having error when trying to make the same on Karmic.

sudo apt-get install upx-ucl

Speedup your flock browser (applied to firefox too)

number.0 — Sun, 25 Oct 2009 05:40:38 +0000

I decided to try Flock on my new Ubuntu Karmic installation, which is running beautifully on my old-boy Toshibar R100. And to make it faster, you may try as I did, I bet it will make your flock much faster when browsing

1. In Address bar type about:config . A warning is displayed, just proceed with the button “I’ll be careful, I promise”
2. In the Filter, type network.http

3. Now, locate the row named network.http.pipelining and double click it to change the value from false to true

4. Do the same to network.http.proxy.pipelining

5. Locate the row named network.http.pipelining.maxrequests – double click and change the value to 30 or higher (I’m using 40)

6. Restart your Flock and see
Hopefully that works for you too

Duplicate a website like Teleport on Ubuntu Jaunty Linux

number.0 — Wed, 14 Oct 2009 07:34:36 +0000

If you are a Windows user, you probably know about Teleport to download or create a copy of a website on your hard-disk

What about on Linux? Well, you have another alternative powerful option: using wget

- To mirror your website:

wget --convert-links -r http://www.yoursite.com

- To download specific file types:

wget –accept=.html,.doc,.docx,.pdf,.xls,.xlsx,.ppt,.pptx –recursive –no-clobber –page-requisites –convert-links –restrict-file-names=windows –domains yoursite.com –no-parent http://yoursite.com/path

Is there any better alternatives? Please share with me.

Looking no more! I found the best Mind Map for my Ubuntu

number.0 — Tue, 06 Oct 2009 08:59:37 +0000

I have been missing Mindmap Manager when switching to Ubuntu from my Windows box and wondering for a while to find a powerful & competitive alternative free solution.

Freemind is the first one that came up on my Ubuntu Jaunty 9.04 system, it satisfied my needs but the graphics seem to be plain & poor compare to the windows counterpart. Here is the screenshot of Freemind.

And today I found out XMind, another great Mind Map software, it comes out as Free and Pro version and available on all platforms. I registered and downloaded the free XMind Ubuntu/Debian package and installed on my Ubuntu laptop. It works great, and the graphics are beautiful

Have a look at the screenshot (It’s sexy, right?) and try yourself
