Colours - London Live Weather

Colours: A Live London Weather Dashboard

By data visualization, Weather, Weather London

Here at The Bartlett Centre for Advanced Spatial Analysis we run a Davis Vantage Pro 2 unit with Solar and UV sensors from a rooftop on Tottenham Court Road. The current output is via our live ‘Weather Dials‘ page, which is all singing and dancing, complete with graphs and updates every 2 seconds. Sometimes however there is a need for something simpler, a dashboard style view that changes background colour to a variety of pantone shades according to temperature:

Made with a tablet in mind and to hang on a wall, ‘Colours’ is designed to be a simple weather application for London at a glance, data updates every two seconds.

500 Words a Day...

500 Words a Day: Academic Writing

By Writing

Its not something many academics admit – but writing is hard, not for all, there are some academics who simply flow words but for many its a challenge. There is nothing worse than the blank page of a Word/LaTeX document, knowing you have 10,000 words to go and only a title or abstract in place. It also depends on your stage in an academic career. Researchers generally have more time during the day to, as the job title suggests, to research and therefore write, lecturers less time (increasingly so) and so on. That said, the ability to do anything else than write the paper/masters thesis/PhD chapter is strong, many academics are excellent in justifying just one more bit of research before they start writing.

If you go through a period of not writing, be it weeks or months, then the guilt as an academic starts to build up, we are meant to write papers as those around will often be only to keen to chip in during conversations. I see it across the board, from professors through to starting out researchers and students leaving the course essay until the last possible minute.  There is a  need to not only get over the fear of starting a new paper but to also form a pattern to take away the worry that can all too easily build up.

It turns out the answer is easy, who would of thought it, and thanks go to Sir Alan Wilson of CASA who i found sitting typing early one morning, turns out he always aims for: Write 500 words a day.

I am at the stage, as head of the department, that my day is not one of research, it is one of almost constant meetings, as such it is rare to find quality time to write. However 500 words is achievable, it can be fitted in between meetings either in one go or in small chunks.

Writing 500 words a day gives you 2,500 a week  – 10,000 a month which is easily a PhD chapter, two working papers, or one journal paper.

It may seem obvious, but it is all too easy to complete a long day without having any words on paper and the aim for 500 words a day is not a mountain. It is not the sometimes recommended 1000 words a day that can turn into a slog and all too easily lead to a writer’s block.

I’ve been doing it for a week – not long I’ll admit – but i have 1 journal article, 1 conference paper and two book chapters all due soon and it has taken away the worry, and if I’m honest the guilt, of simply doing the day job. I go home knowing i have completed the goal and i, therefore, see the completion point, its not building up to the scenario where I have to write 4000 words in a day.

I would add that if you dont reach 500 words, don’t try to write more the following day, unless it flows. The aim is to get into a pattern, a pattern that is long term. This blog post is just over 500 words, of course academic writing takes longer but for anyone out there worrying about output/deadlines/work load then i would suggest giving writing 500 words a day a try.

Virtual Cities: Digital Mirrors into a Recursive World

Working Paper – Virtual Cities: Digital Mirrors into a Recursive World

By Posts

We present our working paper entitled ‘Virtual Cities: Digital Mirrors into a Recursive World‘. The paper comes in at approximately 9000 words and explores visualisation in cities ranging from Twitter to Second Life and through to NeoGeography and The Paraverse. The abstract is below, we have added it as new post as the moment we are mid book chapter on  ‘Smart Cities, Social Networks and the Internet of Things’ and it seemed timely to republish a paper written in 2007 that is still quite useful (although we are obviously biased):

Virtual Cities: Digital Mirrors into a Recursive World

Virtual Cities: Digital Mirrors into a Recursive World

Digital cities are moving well beyond their original conceptions as entities representing the way computers and communications are hard wired into the fabric of the city itself or as being embodied in software so the real city might be manipulated in silico for professional purposes.
As cities have become more ‘computable’, capable of manipulation through their digital content, large areas of social life are migrating to the web, becoming online so-to speak.
Here we focus on the virtual city in software, presenting our speculations about how such cities are moving beyond the desktop to the point where they are rapidly becoming the desktop itself. But a desktop with a difference, a desktop that is part of the web, characterized by a new generation of interactivity between users located at any time in any place.
We first outline the state of the art in virtual city building drawing on the concept of mirror worlds and then comment on the emergence of Web 2.0 and the interactivity that it presumes. We characterize these developments in terms of virtual cities through the virtual world of Second Life, showing how such worlds are moving to the point where serious scientific content and dialogue is characterizing their use often through the metaphor of the city itself.

15,000 Agents: A* Pathfinding

By Unity

Games engines such as Unity are the perfect platform for agent based modelling, they allow a combination of 3D urban cityscapes and navmeshes/grid graphs/point graphs and local avoidance systems. The A* Pathfinding project features an array of techniques for rapid pathfinding or AI development using a low memory footprint.

We have only started exploring the possibilites but the results are intriguing, below features a clip of 15,000 agents using local avoidance, the number could be considerably increased using multiple machines:

A* Pathfinding is available in free and pro versions, it is well worth checking out, we have just upgraded to the pro….
