Mozilla launches US$ 2 Million Wireless Innovation Challenge

Partnering with National Science Foundation, Mozilla Foundation has launched an ambitious US$2 million  Wireless Innovation for Network Society, (WINS) Challenge.

There are two broad categories where the US based entities can apply.

  • Off the Grid Internet Challenge: In this challenge disaster hit communities need to be reached with portable and rapidly deployed wireless communication system.
  • Smart Community Networks Challenge: Reach out to those communities that lack proper internet access in the USA. Mozilla and NSF estimate that there are over 39 million people in the US that lack quality internet.

UPSat – World’s first Open Source Satellite launched into space

This has to be one of the most amazing open source projects of the year. A technology, satellite, which is heavily guarded and mostly utilized by military or government is now available to any budding space enthusiast, living anywhere in the world. For free!

UPSat is a joint initiative of Libre Space Foundation and University of Patras, in Greece. It is designed from scratch as completely open sourced including the hardware. That literally includes the firmware, the chassis and all software related to the satellite. The code and specs can be downloaded from GitHub where they are publicly available.

How to write Urdu, Arabic or Persian text on Web

Languages like Arabic, Farsi and Urdu (AFU) use Arabic fonts and write from right to left rather than the usual left to write. To make any browser display text from the right side of the browser one has to define the following within the HTML tag

html dir=”rtl” lang=”ur”

The DIR tag defines the direction writing on the screen. RTL (Right to Left) or LTR (Left to Write). The LANG tag defines the language specified. In this case it is Urdu (ur).

Inside the HEAD tag we need to add the following meta tag to make it support UNICODE characters.

meta charset=”utf-8″

This tells the browser that non-ASCII characters can be expected and therefore should not garble up text when displaying. Wikipedia defines UTF-8 encoding as:

UTF-8 is an 8-bit variable-width encoding which maximizes compatibility with ASCII.UTF-8 uses one to four bytes per code point and, being compact for Latin scripts and ASCII-compatible, provides the de facto standard encoding for interchange of Unicode text.

And that’s it. Now whatever you write will be displayed properly in the browser. Here is verse from Faiz Ahmad Faiz’s epic poem, Tanhai

تنہایٰ

پھر کوی آیا دلزار، نہیں کوی نہیں
راہ رو ھوگا کہیں اور چلا جاے گا

Insights into Open Data Camp in Amsterdam

The Open Data Camp had many exciting sessions and workshops packed in two very hectic days at Debalie, Amsterdam earlier this month. Speakers lineup was impressive which included organizations like Web Foundation, Open Corporates, Google.org, Oxfam, UNICEF making the sessions engrossing and thought provoking.

Numerous exciting sessions were scheduled that showcased good work done in open data projects including Web Foundation’s Open Data Barometer and Web Index Project. which is measuring the use and adoption of IT in respect of Open Data by governments around the world. This year alone, over 80 countries were considered for the Web Index Project.

How to record calls over Skype

When it comes to finding softwares for making online video/audio calls with reasonable voice quality and no cost to anywhere around the world, there isn’t any other software application which nears the monopoly that Skype enjoys. Regardless of what operating system you have installed on your computer, Skype is compatible with all of them and is used equally by their respective users everywhere in the world. With such extensive usage and hence the wide variety of circumstances in which its used, there often occurs a need to record the calls, and as Skype doesn’t provide call recording services itself, it allows access to some third party applications to do the job.

There are a number of Softwares in market developed exclusively to satisfy the said purpose, among which a tool called Evaer seems to tender the most useful and customizable features with a fairly simple UI.

Software Freedom Day Celebrated in Islamabad

The open source users community in Pakistan has been growing steadily over the years. In 2013, Open Source Foundation Pakistan (OSFP) was established as a non-profit in Pakistan with the aim of fostering the use and adaption of open source technologies within the government, businesses and homes.

Its founding President, Mr Jahanzeb Arshad explains that “the aim of OSFP is to raise awareness about open source software. It’s not only about price but actually it’s the freedom.” He adds, “Freedom to use, share, change and distribute.”

Crazyflie Nano Quadcopter – Opensource and Hackable

Crazyflie is an awesome drone. It fits right into your palm weighing less than an ounce. Surprisingly, it can be equipped with goodies like camera and LEDs. You control the drone with a gamepad (Sony Playstation) over wireless radio. Wow.

The best part about this Crazyflie is that it is completely open source and most of the code is written in Python. Hence, it is to extend and port. Already there are ports to Raspberry Pi and Android platforms.

The Supercomputer that’s Raspberry Pi

Watching this video you will feel how innovative and genius some of us are. Look at them, they have stacked 64 of RaspberryPi’s US$25 dollar computers into a supercomputer of some sort. It boasts a memory of 1TB by cobbling together 16GB SD cards in each of the computers running Linux. And what is more amazing is that it is housed in Lego brick casing. Wow.

If you feel like building your own Supercomputer out of these minuscule computers, the professors at University of Southampton have provided a guide and can be downloaded from their website here.

Marvell has a marvelous plug computer

For a while, I have been searching for a really miniature computer which I could use as an “always on device” to manage various tasks within my home network. Like act as a media repository, file share for home office, manages automatic backups for all PCs on the network and even acts like a small firewall against possible intruders. Marvell plug computer seems to be all that and more.

This little device, called SheevaPlug, is literally built into the power socket. It sports a nice little Gigabit Ethernet for communications and USB interface for external device connections (storage for example). According to Marvell, the device has a Marvell Kirkwood 1.2GHz CPU equipped with 512MB of flash and 512MB of DRAM.

There are also some wonderful commercial uses as well. Here are a few that I would like to use it for:

  • At Trade Shows, no need to carry numerous bulky laptops/PCs/Servers. The organization can carry a bunch of these plug-computers and be in business within minutes.
  • For demos at client location, these plug computers can run applications right off the device and therefore no need to carry luggage around.
  • Act as a miniature firewall within the office environment
  • Act as a small file server for the office
  • Act as a proxy server for all internet traffic
In the coming years, the possibility of other vendors getting into this market including big boys like Cisco who may convert some of its Linux based Linksys devices into miniature servers. And most of them might be powered by Linux OS similar to Damn Small Linux distribution. That will give developers an awesome platform to program and distribute their applications.
