After the success of Open Courseware, MIT is planning to launch free online learning courses. MIT Open Courseware is now 10 years old, wow! The online course will be called MITx. It will not earn you an MIT degree however it will still give you a certificate of completion. The course will be free, the certificate will attract a small fee which is yet to be determined.

It will be built on Open Source and the technology developed for this will also be Open Source.

Time to learn something new ?

I have been using Quicktext as an addon for Thunderbird for a while now and find it very useful.

Recently I upgraded to Thunderbird 7 with Ubuntu 11.10. The Quicktext download doesn’t work beyond version 6. So I modified it to work with Thunderbird 7. It has been working well for me, if you want it try at your own risk.

Download Quicktext 0.9.11.1 for Thunderbird 7.

What does Quicktext offer?

Quicktext is the powerful tool to automate routine and repetitive emails. You can define actions such as Hi [FirstName], and it will pickup the first name to whom the email is addressed to. Similarly you can define templates for standard email replies. You can even define where the cursor should stop.

Looks like HP is going to kill webOS. HP webOS as a part of the Palm acquisition. I sometimes wonder why did HP acquire Palm in the first place?  anyways,  webOS is the new operating system which Palm decided to ditch their OS kernel use Linux as their kernel as Linux has mult-tasking. Since webOS is already based on Linux, they should open source the layer on top. How will this help?

It will make webOS live, there are thousands of applications for the Palm platform which will continue to have moment. Open Source developers can continue maintaining webOS without any cost to HP.

It will give the market a new alternative to Android, where there isn’t really much options today for phone makers. iOS is by Apple only, Symbian isn’t going anywhere and Windows Mobile is a non-starter.

If it gains Momentum, HP could start offering it to their customers. If not people could at-least use the good bits for their applications.

Patents, Copyrights & Trademarks For DummiesEarlier Microsoft sued Android phone makers, now Oracle is suing Google for Android. Patents were to protect innovators instead its being used to stop innovation.

The big old daddies of the IT industry are going after the new companies.

The old ones have nothing new to innovate. Thy are too comfortable in their zone to make the big bold moves. These companies are eventually going to get extinct and are only resting on their past laurels. They are utilising their patent portfolios to make money and stop other companies from innovating.

HTC is paying $5 for every Android phone to Google Microsoft , yes Microsoft! Microsoft makes more money than Google on every Android phone for patents! The business models is similar to the Mafias asking for protection money. The patents hoarders are the new age Mafia.

If you don’t believe me they are going to be extinct? Do your maths. If you bought Microsoft stock 10 years back for $60, today it would be worth US$28. You would have lost more than 50 percent of your value in 10 years. This is for a company that controls the software on 90 percent of the computers.

Now Google is buying patents, not because they need them. But to have a defensive patent portfolio. You see in the tech industry the big 800 pound gorillas never get sued by other gorillas because they have a patent portfolio.

From Google’s Blog:

The tech world has recently seen an explosion in patent litigation, often involving low-quality software patents, which threatens to stifle innovation. Some of these lawsuits have been filed by people or companies that have never actually created anything; others are motivated by a desire to block competing products or profit from the success of a rival’s new technology. The patent system should reward those who create the most useful innovations for society, not those who stake bogus claims or file dubious lawsuits. It’s for these reasons that Google has long argued in favor of real patent reform, which we believe will benefit users and the U.S. economy as a whole.

Google wants to purchase patents from Nortel Network, a company now gone bankrupt (you cant live on patents for too long you see). Microsoft has a license from Nortel Network and fears Google may cancel their license.

Reuters:

Microsoft, which claims a “worldwide, perpetual, royalty-free license to all of Nortel’s patents” following a 2006 deal, said in a filing with a Delaware bankruptcy court that existing agreements should be transferred to any new owner of the intellectual property, which spans many fields.

Google has bid $900 million to buy more than 6,000 patents and patents applications belonging to Nortel, a once mighty Canadian network equipment maker that filed for bankruptcy protection in January 2009.

Glyn Moody says:

I mean, let’s be consistent here: if you want to abuse the patent system, expect to be on the receiving end of similar abuse. On the other hand, rather more laudably, why not stop abusing, in which case you can take the moral high ground when others start abusing the system to attack you?

Its high time we replace the patent system with open source and let the innovation happen again.

This article has a nice list of 50 open source applications for science education.

Open Source: Astronomy and Space Exploration

1. Celestia

A perennial favorite, Celestia allows users to view the night skies from any point on earth at any time or to see how the sky would look from any point in the known universe. The interface is simple to use, and it uses real telescope imagery of stars, planets, asteroids, and other objects in space whenever possible. Operating System: Windows, Linux, OS X.

2. Stellarium

Stellarium is like having your own personal planetarium on your computer. In fact, it’s such an accurate depiction of the night sky seen with the naked eye or simple binoculars that it’s used by many planetariums. Operating System: Windows, Linux, OS X.

KStars

KStars offers the same functionality as Stellarium, plus some tools for amateur astronomers, like an observing list, FOV editor, altitude vs. time tool, and more. It comes with a default catalog of all stars up to magnitude 8, but you can expand it with a catalog of stars up to magnitude 16. Operating System: Windows, Linux.

4. PP3

An excellent tool for teachers, PP3 creates star charts that are detailed enough for use in PowerPoint presentations or books. Note that in order to use it, you will also need LaTeX. Operating System: Windows, Linux.

5. Cartes du Ciel (Skycharts)

Another option for creating star charts, Cartes du Ciel uses data from 16 different catalogs. Don’t let the French name scare you off—there’s plenty of English documentation. Operating System: Windows, Linux, OS X.

6. Open Luna

If looking at pictures of the sky isn’t good enough for you, Open Luna is an open-source project dedicated to sending actual spacecraft into space and eventually the moon. The group’s first mission is scheduled to launch next month. Operating System: N/A.

7. DevelopSpace

DevelopSpace has an even more ambitious goal—developing the necessary technology to enable a one-way trip to Mars in the near future. Students and others who get involved can contribute directly to solving the technical challenges posed by a mission to Mars. Operating System: N/A.

See the complete list.

When I was looking at getting a new wireless router, I started looking at what users had to say about their experience. The first user reviews said the ASUS RT-N16 Wireless-N Gigabit Router is an excellent hardware with poor software. So it suggested to flash the firmware with DD-WRT.

So I decided to get this router and the first thing I did was to load DD-WRT.

Here is what I like about the router:

  • 4  Gigabit Ethernet Ports 10/100/1000Mbps
  • 1 WAN Port
  • 802.11n (Draft)  supports 300Mbps wireless (your device also has to support this)
  • 3 Antennas for extended range
  • 2 USB ports
  • Power adapter works on both 110/240 volts
  • 480 MHz processor which can be overclocked to 533 MHz

The DD-WRT firmware is very easily loadable using the router browser front-end. Its an open source firmware, it makes the router fully customisable and is extremely easy to use. You can plug in a USB hard drive and convert the router into NAS server. Or can be used to share a printer. You can read the documentation here on how to load DD-WRT.

It can also be used to share 3G connection. You connect your 3G dongle on the USB and you need to do some scripting on the router. (If you are not comfortable with command line stuff, this is not for you). You can load the scripts through the web based front end and run them or you can also telnet/ssh to the router. There  are a lot more features you can explore once DD-WRT has been loaded, like you can convert the router into a VOIP server by installing Asterisk. Happy Hacking!

AirJaldi is an organisation which has pioneered the art of creating mesh WiFi networks. They have managed to reach Internet to the hills in Dharamshala, where connectivity is a challenge.

Here is a full writeup about them. Some interesting quotes :)

The open-source community has also dabbled extensively in it, creating a suite of free software. Most of AirJaldi’s work, Ginguld says, was made possible by “standing on the shoulders of these open-source giants”.

“I hope we’ll be remembered for adding some beauty to this place, not as someone who bought the silicon valleys of Pamela Anderson to innocent Dharamshala,” Ginguld says. For him, the Internet is a basic freedom—as important as security, water or electricity.

The London Stock Exchange has said its new Linux-based system is delivering world record networking speed, with 126 microsecond trading times.

The 126 microsecond speed is “twice as fast” as its main international competitors, the London Stock Exchange said. BATS Europe and Chi-X, two dedicated electronic rivals to the LSE, are reported to have an average latency of 250 and 175 microseconds respectively. Netiher company immediately provided details. But many of the LSE’s older and more traditional rivals offer speeds of around 300 to 400 microseconds. Nevertheless, Linux is now standard in many exchanges.

Nginx (pronounced as? engine-X) is beating Apache as a web server in terms of performance. Its being used by WordPress, Hulu and SourceForge. As per recent Netcraft survey, its already the number 3 web server after Apache and Microsoft with 6.62 percent marketshare.

In a test carried out by Linux Journal, Nginx beat Apache by nearly double performance with less than 1/2 the resources. Its able to do this because of its architecture and yes its open source.

Web Server Worker Processes CPU Utilisation Memory Used requests served
Nginx 1 15% 1MB 11,500
Apache 4?? (threaded mode) 30% 17MB 6,500

The good old X Server is finally getting a replacement. Wayland will provide a replacement but can co-exists along side X Server for compatibility and features. It will also reduce the complexity today where for 3D effect, we are running Compiz.

The X architecture has been around for a decades now. It has gone through many iterations and improvements, however it still suffers from complexities and performance issues. These become bigger challenges when you are working on smaller devices such as phones, where X becomes an over head.

The X Server provides a network layer which is useful when you are running application on one device and output is displayed on another. Such as in thin clients setups. However even there X has been replaced by NX, VNC etc. The Qt team ???created Qt Extended (formerly known as Qtopia) which made direct calls to the frame buffer and eliminiated the need for X. This was a useful for embedded devices, however was limited to applications that used pure Qt APIs and didn’t make any X calls, which means all X applications were out. This limited its use, and never became a replacement for X.

Now Wayland is been designed to be a replacement for X and you should see it in your favourite distribution in the next 12 months.  Hold your breath, this would still require applications to be modified to use Wayland APIs instead of X APIs.

X Architecture today.

Wayland Architecture.

Full explanation of the Architecture.

Malsow’s 5 Hierarchy of needs is commonly know to people, this was updated to 8 a while back.

1. Biological and Physiological needs – air, food, drink, shelter, warmth, sex, sleep, etc.

2. Safety needs – protection from elements, security, order, law, limits, stability, etc.

3. Belongingness and Love needs – work group, family, affection, relationships, etc.

4. Esteem needs – self-esteem, achievement, mastery, independence, status, dominance, prestige, managerial responsibility, etc.

5. Cognitive needs – knowledge, meaning, etc.

6. Aesthetic needs – appreciation and search for beauty, balance, form, etc.

7. Self-Actualisation needs – realising personal potential, self-fulfillment, seeking personal growth and peak experiences.

8. Transcendence needs – helping others to achieve self actualisation.

I found the 8th one inspiring and probably answers one of the reasons why people create open source software. It further says:

Inherent in the nature of humans is the desire to improve and better ourselves. This process of going  beyond our current limitations is often referred to as “self transcendence.”  Self Transcendence can apply to any aspect of our being; the physical self transcendence of running faster; the mental self transcendence of going beyond our purely egoistic thinking.

However at the heart of self transcendence is a spiritual concept that we are growing into a more illumining nature and gaining a wider perspective of our true self.

Self transcendence is not competing with others. Self transcendence is a personal journey of self discovery. To practise self transcendence we need personal effort, willingness to change. However self transcendence needs to involve an awareness that our success doesn’t just involve our “little I”, but also the universal self (or bigger  “I”).

Spiritual seekers have experienced self transcendence as the grace that allows them to be aware of the infinite consciousness of inner delight. In this spiritual self transcendence the different religions and spiritual practises converge on the common teaching of going beyond the limitations of the ego and being aware of our higher Source. This Higher Self is called by many different names, but ultimately is beyond any metaphysical concept.

The practise of Self transcendence is not limited to those who are overtly religious. Any human being who strives for greater perfection and a higher perspective is practising a form of self transcendence, and it is this self transcendence that gives us joy.

Here is the above Maslow’s Hierarchy of needs diagram in OpenOffice format if you need to edit.. If you make it better, send it back to me.

The US Department of the Interior is looking for a mailing solution for its 88,000 employees.

Their tender asks for “Microsoft’s Business Productivity Online Suite-Federal (BPOS-Federal)”. They justify by saying:

“Based on extensive market research, the Department determined that although many companies can provide messaging services in general, they either cannot provide services that address the complexity of messaging requirements within DOI, or they could not meet the degree of security required by DOI”

Google points out that BPOS-Federal is a new product, and that there are no case studies or known customers who have implemented this product. In addition, BPOS-Federal has not been properly certified by any government agency at any risk level. Despite all this, the DOI still demands this tool.

This is a good move, it will encourage the US and other  government to consider open source and stay away from proprietary solutions. To find an 800 pound gorilla [read Microsoft] , you need an elephant [Google] :)

Q: Why is an elephant big, grey and wrinkly?
A: Because if it was small, white and hard it would be an aspirin.

While looking for presentation tools, I came across PDF Cube. To use this, you need to convert your presentations into PDF. OpenOffice.org already has this feature of exporting your presentations as PDFs.

You also need to install this utility. On Ubuntu its already there in the  repository, for other Operating system you can download it.

Once your presentation is in PDF just go to terminal and type:

pdfcube filename.pdf

Replace filename.pdf with your actual file name.

Now the keys to use to see the effects during the presentation:

c : Will go to the next slide using a cube transition effect.

z : Will zoom in the center of the slide.

h : Will zoom in the top left part of the slide.

j : Will zoom in the top right part of the slide.

k : will zoom in the bottom left part of the slide.

l : will zoom in the bottom right  part of the slide.

The application is under development and expect to see more effects in the future.

Broadcom which until now refused to open their Wi-Fi  drivers, has released their Linux WiFi Drivers under Open Source.

This is great for Linux users, as Broadcom was one of the few chipsets for which there were no open source drivers. While you could use Windows drivers on Linux using NDIS wrapper, it had its share of problems.

This should also help Broadcom as people can improve their drivers and fix bugs as well.

Two of the other major Wi-Fi chipsets: Atheros and Intel are already WiFi. Also most of the hardware today works out of the box with Linux. As far as graphics is concerned, Intel and ATI (AMD) have both open sourced their graphic drivers well. NVIDIA has good Linux drivers, however they are proprietary. Looking forward to them opening up next.
