Nearly done

Home stretch...

Updated my website recently to add my publications (two accepted... phew) and I'm a few corrections away from finishing—which is surreal. I think as a treat I'll start writing out my acknowledgements; something I'm taking quite seriously. Acknowledgements sections can be an absolute joy when they're not generic "Ooh I'm ever so grateful to ___ for being nice/reliable/trustworthy/there for me" statements in unending lists. I'd like something more personal than that.

Well here goes nothing. Oh and if anyone has any advice on how to make this image below more clear, do write in on a postcard.

Quick one

Just a quicky to say I've added a couple of download links to my personal site. Upcoming paper and transfer thesis. Got another paper under review at the mo.

XKCD's "Simplewriter" presents, my research

The chances are good (since you're reading a blog about PhD research) you're at least vaguely familiar with the excellent xkcd webcomic, and you may know that the creator recently started producing books of labelled diagrams of various types described entirely with only the thousand most-common used words in the English language. If you're not familiar, check this out first. If you are, you'll be delighted to know there's now a simple filter that you can use to try your hand at the art of minimalist explanation. I attempted to explain my research. Here's what I came up with:


My work, using only the the ten hundred most used words in our language: "I am a computer using person, and I work on writing computer-words to make small flying machines (with no person doing the flying) fly around. I want them to fly in a not-stupid way so that if there is a bad event in the world, they can make a group of flying machines and look all over the place where the bad-event happened to find people who are in trouble. They need to be not-stupid so that they find the people quickly, or they might die. It is hard to do because they only have little computers on them and so can't do hard number-work, and they can only talk to other flying machines a little bit (and not all the time). Sometimes there might be a map of where people are and where bad-things are, and we can use this map to help the flying-machines go to the best places where there are people in trouble."

I wrote this on Facebook, but I thought I'd put it here too

It almost came out like a melancholy poem... Well anyway:

Writing a new programme... is like building a machine.
From scratch.
Out of matchsticks and paperclips. 
And you build this massive machine, and some of it has never been built before and you just have to remember how it’s done because you can’t draw; and no one else has ever attempted it.
And you think you’re finished and you step back to admire it, flip the little “on” switch you made and it whirs and clanks and bits spin around and then it prints out a bit of paper with a picture of a duck.
And what you really wanted, was a list of the names of former US presidents...
but you have a duck.
And then you think... Why is it a duck? What part is making it a duck? Is it the printer? Or the bit that sends the instructions to the printer? Or the bit looking in the encyclopaedia? Maybe it got confused and looked up ducks. Or maybe it’s not even looking in the encyclopaedia and it’s just found a duck photograph inside the leaves of a book, and used that? 
So you ask it some questions. But all it can do is print out numbers. The numbers tell you about what it’s trying to do, but it’s a machine and so it’s very bad at explaining.
And you take it apart, and you look at every piece...
and eventually...
after hours...
you find the problem.
You put a toothpick in the wrong place.
ONE toothpick....
and you move it 6mm to the left, and you see from the numbers that... ahah! It’s looking at the correct pages now! No more ducks!
And you put it all back together,
and flip the switch,
and you get a picture of a hat

UAV Demo Vid

I made a video. Lucky me! Not much of my work in it, but it was a nice distraction from the day-to-day.

Three Minute Thesis

First, quick thank you to everyone who gave me supportive and thoughtful comments on my last post.

Second, a few months ago I competed in the Faculty of Physical Science and Engineering "Three Minute Thesis" competition, where I had only 3 minutes to outline what I do and what my research represents. I managed to come away with £50 and a second place position, and now (no thanks to the people who uploaded the video without telling me) my little talk is available online. Enjoy!

Computers and Coal-coloured Canines

Despite being something I very rarely mention to all but a few close friends, I feel rapidly that I'm beginning to need more than one sole outlet for the single biggest obstacle to the completion of work in my PhD, namely, that for the last four years I've suffered from what most people call Depression, and what a different sort of Doctor would call Major Depressive Disorder.

There are plenty of excellent sources, valued reader, that explain the precise details of this condition far better than I could possibly attempt; and a short jaunt to your favourite search engine will surely confirm this. Nonetheless I feel compelled to add as best I can some particulars of my situation and how it pertains to my performance (or lack-thereof) in my research at this time. I include a few silly cartoons I made in moments of despondency. Make of them what you will– I appreciate some of them may seem almost narcissistically self-piteous, but I hope they might serve some purpose in explaining or allowing people to empathise with this condition.

~~~~

The popular comparison for depression is that of a black dog– the larger and more cumbersome the better– draping itself across your back or lap and sapping you of the energy and will to continue in the pursuit of daily things. I have mixed feelings about this analogy: for on the one hand it conveys the almost physically tangible "weight" of hauling around a brain deficient in serotonin and intent on ruining your day, while on the other it equates the condition to a creature many of our species find adorable and cute.

As such, in my own mind I've always preferred to imagine a more amorphous blob. A sort of sentient lump of tar malevolently swamping your work and your faculties of reason. While I appreciate it may be impossible for some to consider something affecting you very pertinently in your higher mental faculties, it is something worth keeping in mind whenever a friend confides in you that they have such a condition. It's still a physical ailment: Something in my brain isn't working properly, and it seriously affects my ability, in turn, to work. I would not dare to pass judgement on similarly afflicted friends, as I have heard some do, that suggests they are merely "lazy". In the same way a severed leg would seriously impede one's ability to run (unless replaced by a suitable prosthetic), an abnormal mixture of hormones in the brain seriously impedes one's ability to get anything done (for which, perhaps sadly, no such prosthetic can provide a cure).

This need not even be serious or important work. One of the reasons I feel privileged to know friends who can empathise with this rather stupid condition is that some days you really long to share with someone that you managed to brush your teeth, and are feeling distinctly proud of this achievement.

Ultimately, aside from lacking any kind of feeling of motivation to begin a task, I have found that one's own inner-monologue often confounds the matter. Consider a state of lowered mood, which has prevented you from achieving a pre-determined goal of fixing your buggy code by a given day. Now consider the feeling of failure gained from such a missed deadline, and quickly one can appreciate the sullen downward spiral of self-doubt and misery which results. Again, this may sound hyperbolic or even self-centred, but its veracity cannot be fairly doubted and is supported in lines such as that by the ineffably insightful Stephen Fry when he describes the "blackness, lethargy, hopelessness, and loneliness". Notice the inclusion of the word 'lethargy'. 

In the event I alternate between feelings of vague contentedness with the progress of my Transfer Thesis and relevant research, and almost overwhelming negativity wherein I convince myself I am incapable of any significant achievement or completion of my Doctorate. For now, at least, here I remain: holding on to the hopes that I will succeed despite this encumbrance and with the support of those I can rely on, and that I will not succumb to the terrifyingly real prospect of having to stop what I'm doing and move elsewhere. 

I might have just wasted ten minutes of your time with this incoherent ramble, for which I apologise, or I may have provided a tiny glimpse into what I think about every day that I sit in this office. Either way, and whether or not I know you personally, thank you for taking the time to read all this and give me an opportunity to voice myself in this small way.
