Ubuntu 7.10 on DELL E1505 Notebook

I installed Ubuntu (Gusty Gibbon) on my Dell notebook and I felt the beauty of it from the very beginning.

The two most interesting features I see:
1. Read/Write facility to NTFS (Windows) partitions
2. Easy configuration of restricted drivers (no need to worry about setting up your ATI video card :)

Perceptron in Java

I'm following Neural Networks class for my final year and I felt it's a cool subject. I'm still a newbie in this field. But I gave a try to implement a simple perceptron to train few logic gates. It was a cool experience.

HUAWEI ETS 2251 with Ubuntu 6.10

We recently purchased a CDMA data phone and I wanted to connect to the Internet with Linux (Ubuntu 6.10). Try the following steps:

1. plug-in the USB cable (your cable should be Serial (phone side) to USB one).
2. sudo dmesg -c

you should see the following at the bottom

ti_usb_3410_5052 2-1:2.0: TI USB 3410 1 port adapter converter detected

if you see ti_usb_3410_5052: probe of 1-1:1.0 failed with error -5 after the above line then copy the following lines,

#TI USB 3410

SUBSYSTEM=="usb_device" ACTION=="add" SYSFS{idVendor}=="0451",SYSFS{idProduct}=="3410" \

SYSFS{bNumConfigurations}=="2" \

SYSFS{bConfigurationValue}=="1" \

RUN+="/bin/sh -c 'echo 2 > /sys%p/device/bConfigurationValue'"


and save them as /etc/udev/rules.d/026_ti_usb_3410.rules


Now run sudo dmesg -c again and you'll see the following two lines,

ti_usb_3410_5052 1-1:2.0: TI USB 3410 1 port adapter converter detected
usb 1-1: TI USB 3410 1 port adapter converter now attached to /dev/ttyUSB0



3. Now configure the /etc/wvdial.conf as follows, please note that you need to replace your given username, password and phone number with my configuration (abc@prepaid, 1234, #777) given here.


[Dialer suntel]

Modem = /dev/ttyUSB0

Baud = 230400

Phone = #777

Init1 = ATZ

Stupid Mode = 1

Dial Command = ATDT

Username = abc@prepaid

Password = 1234


4. Now type sudo wvdial suntel and enjoy the Internet. If you can't browse then plese add the DNS addresses to /etc/resolv.conf (these DNS addresses can be found in the command line while connecting).

Thanks Farhan Naeem for sharing knowledge on this matter
