Why google don't index my forum powered by phpbb 3.0.4 www.dotaart.com

Tried really hard to solve the dynamic link problem.

Finally resolved it with the help of Advanced phpBB3 SEO mod Rewrite

Don't forget to change you "AllowOverride none" to "AllowOverride ALL" to enable mod_rewrite for your websites. I am stunk at this point for quite a long time ...

For me this is modified at

"/etc/apache2/sites-enabled/000-default" where I configured my virtual hosts.

Now the forum looks better.

Originally, the URL look like this,

"

www.dotaart.com/viewforum.php?f=2

"

Now the url looks static like this

"

http://www.dotaart.com/dota-allstars-logo-art-f2.html

"

This is more search engine robot friendly.

Which is considered as part of SEO (Search engine optimization)

However, I still don't manage to get google crawl my page.

In the web master portal, I can see that google didn't index a single page of my site.

I'm sure this is a problem of duplicate contents, however, really difficult to fix

But now, www.dotaart.com, a forum to share dota video, images, and musics has more than 2000 clicks from 40 countries in just 2 days. I think it will grow more and more popular in the near future.

Finally tcpdump on GPhone G1 Android

Timur helped me a lot with this.

Step 1.
You need to get the tcpdump binary from here or here.
If you want to know where this binary is from, refer to Timur's post about cross-compilation.
If you don't want to bother, just download the tcpdump binary.

Step 2.
Install Android SDK in your machine.
See here for details.
They have good support for Windows, Linux and Mac.

Step 3.
Go to android-sdk-linux_x86-1.1_r1/tools
or xxx/tools depending on which build version of android you are using.
run
"sudo ./adb push ./tcpdump-arm /data/local"
You can push the tcpdump binary from your computer to the phone's directory "/data/local".
According to Timur, we can remount the gphone and make other directory writable to user "shell", however, by default, I only found "/data/local" is writable to user "shell" (maybe wrong, but at least it works)

Step.
run "sudo ./adb kill-server"
run "sudo ./adb shell"
Now you have logined into Gphone's shell command

You can see this
"
* daemon not running. starting it now *
* daemon started successfully *
$
"

Run "su"
You will see
"#" and now you are in root mode.
(Our Gphone is a holiday version which is not for sale.
For normal GPhone, I guessed, you can not enter root mode, hence not be able to run "tcpdump". For GPhone Dev version, you can definitely enter root mode)

Run
"cd /data/local"

Run
"chmod 777 tcpdump-arm"
To change the binary executable

then
run
"./tcpdump-arm"

If you see
"tcpdump: no suitable device found"
Then it means that you need to be root to run tcpdump.

Have fun dumping traffic on your GPhone Adroid

Android SDK adb shell error: device not found

Thanks Timur for pointing this link to me.
Really helpful.

I followed all the steps to install Android SDK on a Ubuntu Linux machine.
I went to the "/android-sdk-linux_x86-1.1_r1/tools" directory and run "adb shell"
it replies,
"
* daemon not running. starting it now *
* daemon started successfully *
error: device not found
"

The problem is that we need to run everything with root.
So by any chance, if you met the same problem with me, run

"

sudo ./adb kill-server
sudo ./adb shell

"

Then you can use "sudo ./adb push" or "sudo ./adb pull" to copy file between a Android Gphone and a computer

GNUPlot: How to remove the blank margin space on the left

When you plot a figure using gnuplot, sometimes, there will be an extra blank margin on the left. To make the figure more condense, you can use a bash script to remove the extra blank margin. The basic idea is to adjust the Bounding Box for eps more intelligently.

Usage:
bash fixbb *.eps

The original image may look like this

The original eps file will be replaced with the adjusted eps file

The new eps file may look like this.




You can download this script from here.
Or, copy the following lines into a file named "fixbb" or something else whatever you like.

You can also copy this file (Assume you are using Linux)
to /usr/local/bin
and run "sudo chmod +x /usr/local/bin/fixbb"
Then in your terminal, you can directly run
"fixbb *.eps"

This script helps us a lot for our paper.

Remote desktop from Mac OS X 10.5 laptop to Ubuntu linux 8.10 desktop server via VNC

I have a Macbook and want to connect to my ubuntu desktop machine via remote desktop. It seems really trivial to do this.

Step 1. Open remote desktop preferences in your desktop linux machine
System->Preferences->Remote Desktop
Step 2. Enable sharing, better check all
Step 3. Enable Security, the password is limited to be 8 characters at most ...
Step 4. In you mac, download and install VNC client for it. JollyFastVNC is a good choice.
Step 5. Using your VNC to connect to your remote Linux machine.

I suggest not use encryption in your desktop's remote desktop setting.

Have fun!
