Solved: Setting up D-LINK DWA-525 (RaLink Device 3060) Wireless Desktop PCI Adapter on Fedora 14 Linux

D-Link DWA-525 Wireless N 150 Desktop Adapter

My new “desktop grade server machine” at home has a 802.11n wireless PCI adapter namely D-LINK DWA-525 Wireless N 150 Desktop Adapter.  An adapter like this plugs into one of the PCI slots and connects to a wireless or Wi-Fi network. This helps to keep the machine anywhere in the house and not necessarily near a router or Ethernet port.

On my desktop, I did a minimal or base installation of Fedora 14 Linux. Fedora was not able to recognize the wireless adapter and hence could not connect to the Wi-Fi router at my home. But with some efforts, I was able to make the adapter work on Fedora 14. Additionally, I was also able to configure the wireless adapter from the command line. What follows is a crisp tutorial with the required steps to setup DIR-615 PCI adapter on Linux.

Solved: ‘requires bundle org.eclipse.wst.xml.core’ error, while installing Google Plugin in Fedora Eclipse

The simplest way to get started with developing for Google App Engine, Google Web Toolkit and Google Wave is to use the Google Plugin for the Eclipse IDE. This plugin installs the SDK as well. Eclipse’s built-in wizard to add new software (plugin) makes it very easy to install the Google plugin. This wizard can be supplied with a URL (http://dl.google.com/eclipse/plugin/3.5 in this case) to a download site. Henceforth, Eclipse takes care of downloading and installing the plugin, along with associated dependencies, bundle or required software.

However, for me, installing the Google Plugin didn’t go as smooth as expected. I have been using Fedora Linux on my laptop since the last 5+ years. Fedora ships with the Eclipse IDE. When I tried installing the Google Plugin in Fedora Eclipse, I faced the following error. Read the rest of this entry »

Solved: Garbled text in Putty

Putty is a popular and free Linux terminal/shell client for Windows. It allows one to connect to a Linux server using SSH (Secure Shell) or Telnet. I have been using it for as long as I can recall. But this issue of garbled text in Putty is what I have been ignoring, until yesterday.

Yesterday, I had setup Paradox database using DOSEMU on Linux, for a client. On Putty, the Paradox interface showed garbled making it unusable for the client. My instant suspect was DOSEMU. A quick check revealed that it’s happening with other apps too - those with a ncurses or text based user interface. Read the rest of this entry »

Web Scraping with Firefox and PHP, using XPath

Last year, I faced two projects which required automated Web scrapping – to aggregate content from web pages. I evaluated different methods for Web scraping with varied level of success. Thanks to the changing structure of Web pages, non well-formed pages and URL redirects.

Amongst using regular expressions and DOM (Document Object Model) parsing, I used XPath too. XPath works great for well-formed Web pages. Read the rest of this entry »

My list of must-have Android apps

Ever since I ordered and got my Android Dev Phone 1 (a.k.a. ADP1), I have been taking it through various updates. The phone shipped with Android version 1.0 and upgraded to version 1.6. After 1.6, I opted to go for ROMs from CynaogenMod.

Each time, I upgrade my phone, I wipe off its data. This is because I took the upgrades as an opportunity to wipe off applications which I install, but do not use or use occasionally. But, following is the list of Android applications which I crave to install after each wipe off. These applications are my must-haves on my Android phone. Read the rest of this entry »
