So apparently Dhiraagu has been under some sort of attack since day before yesterday and that is the reason Dhiraagu Internet subscribers are getting patchy Internet connectivity. I am not sure what kind of attack it is under but I presume it is of the DoS variety aimed at driving down their QoS levels. From the looks of it, the attack seems to be being targetted at, or atleast affecting, the Internet proxy/filters and DNS servers at Dhiraagu. Anyway, if you are as frustrated as me with patchy Internet then here's a quick fix solution: install and use a VPN.

A Virtual Private Network working over the Internet connects one computer to another via a private virtual "tunnel" and routes data between the computers. A VPN will allow you to browse the Internet via the remote computer's Internet connection so you aren't affected by (some) issues affecting your ISP and bypasses restrictions imposed by your ISP. As opposed to using a remote proxy server, a VPN can route all your Internet traffic via the virtual tunnel allowing you to bypass all local restrictions entirely. Use of a VPN, on laptops and mobile phones, is highly recommended if you frequently connect to Wifi hotspots at restaurants, airports etc to keep your data secure from being snooped.

Free VPN Services

There are many VPN service providers, including those that offer free services. A list of VPN providers is available at start-vpn.com. Here are a few I've used and tried.

Ivacy
Ivacy has both free and paid services. I quite like their volume-based paid plan which currently gives 1 GB for 0.67$ and a wide range of geographical locations for an end-point. The geographical location allows you to access services such as BBC iPlayer and Hulu which are region restricted. They even have a Ivacy Firefox extension that integrates into Firefox, which is handy if you use the browser.

Ultrasurf
Ultrasurf is extremely easy to use and their client, a 1.1 MB download, runs straight without requiring any installation.

UltraVPN
UltraVPN offers OpenVPN-based VPN access with a free registration process. They have a cross-platform open-source client allowing you to use it on Windows and Mac OS.

PacketiX VPN
PacketiX VPN is free and offers several nifty featues. Their Secure Internet Test Service gives access to a secure VPN for web usage and, for the more geek minded, their VPN Online Test Environment allows you to create a virtual VPN hub that connects together several of your devices.

ProjectLoki
ProjectLoki offers a public VPN server, connected through their free 1.1 MB client software, which you can use as a guest. Their paid services include more data transfer. They also offer special VPN server software that you can run and have your computer(s) connect to.

Happy New Year btw

There are over a billion people across the world that are in perpetual hunger, starving to death. Being hungry for these people is not the same as what we experience when we've missed a meal or two or had very little food. For these people, they are forced to bear with the hunger day in day out, without a clue to when they could have some food - ANY food. Their body burns through the fat reserves, if any, they might have till there is no more and fails to function: death. The World Food Programme estimates that 10 children die from starvation every minute. 1/6th of the world already live in constant hunger and that's something we the more fortunate should be sad about - really really sad about.

What is equally sad is that hunger exists not because there is not enough food in the world. Food production has outpaced the growth in population and there is a surplus of food across the world. While there are many reasons why there is hunger, the problem can largely be attributed to unequal distribution and poverty. Unequal distribution results from political and economic obstacles that control the flow of food from food producers to those in need. Poverty, especially extreme poverty, means that people who really need it cannot afford to buy food or grow food. Natural disasters, political instability and wars push the financially challenged to poverty and starvation. People are dying of hunger essentially because they are too poor to stay alive.

Maldives, where there is so little food production, where almost every single food item we consume is imported, is an especially fragile society. Were there to be a war (and not necessarily within the country) or any other event that breaks down the import mechanisms, we'd all join the billion starving just as Maldivians have in such past events.

Help put pressure on governments to end hunger. Donate towards feeding the starving. Do what you can to help end poverty. If you are looking to get inspired, read up on Norman Borlaug who is credited with saving a billion people from starvation thanks to the high-yield, disease resistant variety of wheat that he engineered.

Hope none of you has to ever face chronic hunger.

I was watching a presentation tonight titled "African fractals, in buildings and braids" (on TEDTalks) and was totally absorbed in it when an African game board shown in it caught my eye - the board looked eerily similar to something I knew: an Ovvalhugondi. I had always been under the impression that "Ovvalhu" was a distinctly Maldivian game but just like many other supposed Maldivian games of the likes of "Koraa" and "Baibalaa", I wondered if Ovvalhu too was just another foreign game that had been absorbed into our culture. Anyway, I was compelled to look up more about the mentioned African origin game called "Mancala".

Finding out more about Mancala was a much easier task than I thought. Rather than it being an obscure game played in a lone part of Africa that had little mention in any literature, Mancala was literally something of a global phenomenon that had many a mention of it, played all over the world and had dozens of online shops selling the boards. There even were online versions of the game! Mancala or Manqala in Arabic, basically refers to a class of games that all have similar game play - the objective always being to capture more "stones" than the opponent. There are a number of variants (see Wikipedia's list), as adopted by different countries or areas, that differ in the finer details of how its played. Apparent differences obviously include the number of pits in the board and the number of "stones" used in play.

I might be wrong (very wrong, infact) but from what I read I suspect that Ovvalhu takes after the version played in South India or possibly the version played in Ghana. Ovvalhu may not be our national game but Ghana's Mancala variant called "Oware" is supposed to be their national game. I found it amusing that the names sounded similar but that might just be mere coincidence(?!). A similarity that certainly is not a coincidence is that Maldivians also used to play Ovvalhugondi with "Laagulha" (picture), ie. the seed of "Kashikumburu", which is what Oware is supposedly played with (in the Caribbean atleast).

What was even more interesting, to me, was to learn that Mancala (or atleast some variants of it) had been analysed using combinatorial game theory. The game of Awari was tackled by two Dutch scientists who generated the entire state-space for the game - mounting upto almost 9 billion positions - and cracked the perfect play for the game (here's their paper). Perfect play is a game theory term for a strategy or set of moves that guarantees a certain outcome in a game - a win or a draw at the least - if the game allows so, mathematically. I have no interest in Ovvalhu but I find such computational challenges almost erotic. I'm very much tempted to attempt analyzing Ovvalhu for a perfect play as well, so I've added it to my list of future boredom-killer projects.

Anyway, though it is pretty conclusive that Ovvalhu is not a Dhivehi game, I think it is interesting to learn that it certainly is one with an exciting history and background!

I'm releasing an update to the Hulhule FlightInfo PHP class I released late last year as a response to a feature request I received recently. The update adds support for flight information for all the days as available on the Flight Information Services site rather than the current-day-only mode that the original script supported. A small demo script is packaged in the download to highlight the usage details.

The Hulhule Flight Info class simplifies access to the flight information by doing the dirty work of grabbing the HTML page from the FIS site, parsing it, extracting the required information and making it accessible as a multidimensional array. It supports grabbing both the arrival and departure information and is easy to use. It has since been integrated into a few sites by different people.
