Amber Jain’s list of *free* books available online for free

with one comment

Quoting Stewart Brand:

Information wants to be free

I guess after reading the preceding quote, the intent of this blog post is clear.

I wrote a related blog-post sometime back: Links to *free* legal ‘readable stuff’ online.. This post is an extension of the idea behind that post.
I’ll post links to books (in no particular order) that are available online for free here. I’ll update this list whenever possible. If there are similar links/resources that your know of, post them in comments:

0. The C Book, second edition (by Mike Banahan, Declan Brady and Mark Doran)
This was originally published by Addison Wesley in 1991. This book is no longer in print though it can be read online for free.
The C book

1. Handbook of Applied Cryptography – fifth printing (by Alfred J. Menezes, Paul C. van Oorschot and Scott A. Vanstone)
Handbook of Applied Cryptography

Quoting Stewart Brand:

Information wants to be free

Richard Stallman restated it as follows:

I believe that all generally useful information should be free. By ‘free’ I am not referring to price, but rather to the freedom to copy the information and to adapt it to one’s own uses… When information is generally useful, redistributing it makes humanity wealthier no matter who is distributing and no matter who is receiving.

I guess that preceding quotes pretty much clarify the intent of this blogpost.

In this post I’ll link all websites (in no particular order) that provide any number of ebooks/magazines/journals/thesis/dissertations etc. online for free. I’ll update this list whenever possible. If there are similar links/resources that your know of, post them in comments:

[Cross platform + Free] Voice and Video chat programs

with 8 comments

Version: 0.2 (includes update 1)
Changelog: Removed ratings, added other programs to this list (without description).
Last updated: October 18, 2009

Hello,

I formatted my XP installation a few days ago (and I installed Kubuntu 9.04 that dual boots with OpenBSD 4.5). After some time when I wished to use voice chatting services (Free PC to PC voice calls), I found out that most popular voice/video chat services like Yahoo messenger, Google chat etc. were not available/supported by commercial vendors on Linuxes/BSDs/Unixes. 😦 I searched Google and found following voice/video chat program options:


[ Mind you, most services mentioned below are Free and supported on more than one platforms. Moreover, I tested only voice/text chat (and NOT video chat), so the ratings and reviews involve only text/voice chat. ]



1. Ekiga:
Description- Ekiga (formely known as GnomeMeeting) is an open source VoIP and video conferencing application for GNOME. Ekiga uses both the H.323 and SIP protocols. It supports many audio and video codecs, and is interoperable with other SIP compliant software and also with Microsoft NetMeeting. Free Your Speech!

Platforms supported- Atleast Linux/Unix/BSD, probably Mac OS X, Windows XP/Vista.

My views: Works great! I tested only Voice chat. Installed easily. Iirc, no configuration was needed.



2. WengoPhone (now called “Qutecom”):
Description- A single application to talk, chat and share for free with anyone.

Platforms supported- Atleast many versions of Linux, Mac OS X and Windows.

My views: I never installed this. But reviews about WengoPhone on internet point out that it should be easy to install and use.



3. Skype:
Description- Free calls, video calls and instant messaging over the internet.

Platforms supported- Versions exist for Linux, Linux-based Maemo, Mac OS X (Intel and PPC), iPhone OS (iPhone and iPod Touch), Microsoft Windows (2000, XP, Vista, Windows Mobile), and even Sony’s PSP. (Source: Wikipedia)

My views: Works great! I tested only Voice chat. Installed easily. Iirc, no configuration was needed.



4. Jabbin:
Description- Jabbin is an original mashup of Social Network, Instant messaging and VoIP developed entirely on the widely-used and open protocol, Jingle/XMPP, and open source software, including Asterisk, Openfire and Jobill, a billing system.
Jabbin is an Open Source instant messaging program that allows free PC to PC calls using the VoIP system over the Jabber network. The Release 2.0 use the libjingle protocol.

Platforms supported- It appears that this works on atleast recent Windows releases and many Linux/Unix/BSD distributions.

My views: I tried installing it only once and failed. So this may prove to be a useful program but don’t ask my opinion.



5. TokBox:
Description- Free video chat and video mail to anyone in the world without downloads or hassles. Video call your AIM, MSN, GMail and Yahoo buddies. Tokbox is a free service that lets you talk with your friends over live video. Here’s how it works: you sign up and we give you a link. When you want to talk with anyone, just give them the link – they click and you chat. Embeddable on all websites and social networks. No cost. No prepaid minutes. Really free.

Platforms supported- Talk through your browser. No chat client needed. There is no client required. This service from Meebo works from within a modern web browser (e.g. Mozilla Firefox).

My views- In my case, I could neither send nor receive any voice data. It appeared as if everything was working right, but I could not use this service.



That’s it…If I find some other free and useful services, then I will post them here as updates.



UPDATE-1: There are many other programs that are pretty nice to be added to this list. Mind you, I had not used most of these programs myself:
1. Empathy: Empathy is a messaging program which supports text, voice, and video chat and file transfers over many different protocols.
2. Tinychat: The web 2.0 site for making free, disposable chat rooms with live audio and video.
3. Gyachi: GyachE Improved supports almost all of the features found in the official Windows Yahoo! Messenger client: Voice chat, webcams, faders, ‘nicknames’, audibles, avatars, display images, and more. (Source: Wikipedia)
4. Pidgin: As of version 2.6 (released on August 18, 2009) Pidgin has a voice/video framework which uses Farsight2 and is based on Mike Ruprecht’s Google Summer of Code project from 2008. That release provides the ability to have voice/video conversations using the XMPP protocol (including Google Talk), though the implementation is not yet fully complete. The framework will also allow for voice/video conversations on other protocols, such as MSN and Yahoo, in the future (Source: Wikipedia)

Other possible options include Kopete, gaim-vv (many of these programs are limited/reduced support applications).
Another option requires you to install some supported OS for your choice of chat client inside a virtual machine.

Note: I’m not planning to update this article now (unless I find something really amazing) because you can retrieve all such information from Google. If you know of similar programs, post them in comments.

Have fun! 🙂
