|Miscellaneous - Running|
Today I took part in the Green Corridor Run for the first time, after having missed the inaugural 2013 edition due to a cold. It was a blast! This is the best trail run I have experienced in Singapore so far, and it certainly lets you forget for a while that you are in a densely populated city state. I've been familiar with a 2km stretch of the Green Corridor before, which forms part of my running route from work to home, but today was the first opportunity to explore the remaining 8km.
The organization of the event was superb. The race started at the historic Tanjong Pagar Rail Station and ended at the old Bukit Timah Rail Station. Flag-off was in several waves, due to the large number of participants. The first wave started at 9am, which is unusually late for races in Singapore, considering the hot and humid climate. But the real concern today was the rainy weather, with several heavy downpours. Luckily, the skies cleared for a while and off we went! It was a very wet and muddy affair, with many puddles along the trail. And shortly before I reached the goal, it started raining heavily again. In light of this, the shuttle bus from the finish area to Dover MRT was greatly appreciated.
Hopefully, the Green Corridor will be preserved for future generations and many more events will be held along it. This is especially relevant in light of recent plans to develop the Tampines Bike Park, one of the very few other places where trail running is possible in Singapore. Below is a map of the entire Green Corridor, taken with my GPS watch today. A fullscreen version of the map can be found here.

Check out this article I wrote about the mobile game "MeQuanics" for the QuantumBlah blog. As outlined in more detail in the blog, the game is based on the surface codes of topological quantum computation, with the aim to compactify the codes for certain quantum information tasks, thus reducing the amount of resources required for quantum computations.

Imagine we have a Linux-based webserver using MySql, but phpMyAdmin isn't available for maintaining the databases. In that case we can SSH into the server and use the command line instead. For a brief summary of basic MySql commands see e.g. here.
Individual tables or entire databases can be easily removed using the drop command, but there is no straightforward way to delete a large number of tables from a database. I encountered this problem when attempting to upgrade a Joomla installation from v1.5 to v2.5. When I wasn't happy with the result of an upgrade attempt, I would first make tabula rasa by deleting the newly created mysql tables before making another attempt. Let's say the database in question looks like this:

Intimidated by the prestigious nature of this conference, I didn't even try to apply for a conference talk at QIP 2011 (10th-14th January) and confided myself with a poster presentation. It was shortlisted for the "Alice+Bob Award for Original Imagery", but unfortunately got beaten by another poster that was entirely hand-drawn!
The poster was created with the help of the baposter LaTeX class. I might elaborate on the technical details of this work once I have a bit more spare time. For the time being, feel free to download the source code and experiment with it yourself. :)

Here is the conference talk I gave at the AQIS 2010 conference in Tokyo, Japan on 28th August 2010. It outlines our various findings related to permutation-symmetric states of n qubits, the Majorana representation and symmetric state entanglement classes.
The presentation contains animated vector graphics which may not display correctly on some PDF readers, so to be safe please view it with the Adobe Reader (v9 or higher, Win, Mac or Linux). If you want to learn more about the technical aspects of this LaTeX beamer presentation, please have a look at this article where I outline most of the points in detail.

Recently the Design Office of my university acquired a 3D printer, and they offered free print-outs during a trial period. This was a perfect opportunity for me to bring one of the abstract spherical functions appearing in my work to life. The function is closely related to the icosahedron, a regular polyhedron, in the sense that it has an icosahedral rotational symmetry. A more detailed description of the function as well as its relation to quantum mechanical entanglement can be found further below.
