Installing Ubuntu 7.04 (Feisty Fawn) on Dell Inspiron E1505 (6400)

In a previous article , I have described my installation notes for install Ubunty Edgy on my Dell Inspiron E1505 (Inspiron 6400) Laptop. Today I decided to install Ubuntu Fiesty (7.04) on that laptop to get all the latest upgrades. Here are my installation notes:

A quick note about important configuration elements of my laptop: 128MB ATI MOBILITY RADEON X1300 HyperMemory Card, Dell wireless 1390 card, and Integrate sound card.

Most Imp: Use the alternate install CD to install the ubuntu feisty on your laptop. Feisty standard desktop CD fails to configure the graphics card, and hence is not a good option.

WiFi in India: Opportunities & Challenges

Wi-Fi Alliance has published a report about WiFi in India titled The Future for Wi-Fi in India: Opportunities & Challenges .

"The overall Indian Wi-Fi market (including WLAN hardware, systems integration and software services, not including embedded devices, laptops) is predicted to grow from the current $41.57 million to exceed $744 million by 2012 (CAGR of 61.4%). The necessary market drivers are in place to propel the growth, development and deployment of Wi-Fi into a mainstream technology across the country."

Installing Ubuntu Edgy (6.10) on Dell Inspiron E1505 (6400)

I recently bought Dell Inspiron E1505 (it's Inspiron 6400 in small business section of dell website). Here goes my notes based on Ubuntu 6.10 (edgy) installation on it (as dual boot).

First, my configuration:

  • Intel Core Duo 2.0GHz, 1 GB RAM
  • 128MB ATI MOBILITY RADEON X1300 HyperMemory Card
  • 120 GB 5400RPM SATA hard drive
  • Dell wireless 1390 card
  • Dell 350 Bluetooth module
  • Integrated Broadcom 10/100 network
  • Integrate sound card

Most of the hardware was recognized automatically by the ubuntu installation. Audio was working great. Wireless and graphics required following steps. (I have yet to test bluetooth, so no notes on that yet)

Pervasive Computing - the next era of computer science.

PervasiveComputing.net is intended to be a information and news website. It will cover various new developments happening in pervasive computing area - basically mobile computing, sensors, networking, security/privacy, ubiquitous access to information, and related fields.

We use the term 'Pervasive Computing' to loosely define the advancements in computer science, where pervasiveness of computing and networking works together to enhance human life in new and imaginative ways. The main ideas were represented long time back in two classical papers. First was published in July 1945 (yes, it's 1945!) - As We May Think by Vannevar Bush. It discussed a hypothetical device called 'memex', that can store all your information, and can recall it in a simple and fast manner. To quote it directly
