On the importance of taking notes. [Weekly Head Voices #38]

Post summary: Part one is about friends graduating from Evil School, part two is rather short mentioning vague bits of good news and part three is 100% time management and productivity boosting goodness! Feel free to skip, skim or reorder!

One

On Thursday, February 10, 2011, my dear friend Mister Krekel graduated from Evil School after years of hard work and evil-doing, and will henceforth go through life as the formidable Doctor Krekel. Please do watch out.

The joyous transition took place in the Evil School’s Academiegebouw in Leiden, and this time yours truly (I’m referring to me in a round-about fashion) even had the great honour of playing a part in the formal proceedings. If you’re curious as to what exactly this ritual constitutes, see this previous edition of the WHV on the graduation of another terribly evil colleague. I believe that the bunch of us now constitute a bona fide Axis of Evil. No, the evil jokes can unfortunately not stop yet.

The Party was held in a secret cafe nearby. You will notice that I’ve capitalised Party, as it was not your average run of the mill Evil School graduation affair, but a social event of note. Here in Holland, the PhD defence and graduation are a combined affair, and so the whole day is dedicated to just one person. It is actually very special: People take time off from work, sometimes even temporarily put aside their differences, and travel from all over to attend the festivities. It’s like a wedding, except that there’s only one of you. I can only recommend it very highly. At the Party, everyone had clearly read the memo, and they were there with that singular goal in mind: Celebrate the freshly minted Evil Doctor. Presents were given, speeches were held, photos were shown, beer was imbibed and, flying in the face of all advice concerning the mixing of alcohol, cameras and social networking, the best evil photographer in town, who’s coincidentally also in Evil School, took the most amazing photos that you should be able to see on Facebook if you’re one of the privileged few to belong to The Network, also known as The Friends of the Axis of Evil.

On the good news front, you’ll see (or not) on the list of EuroVis 2011 conditional accepts, that a paper by cool colleagues from far away, to which I contributed a small part, has been conditionally accepted, and hence has a significant chance of being presented at said event in Bergen, Norway (May 31 to June 3). We also have plans to submit a poster (or two), so there’s an even more significant chance that I will make an appearance at this fantastic conference! We’re also cooking up various odds and ends that will hopefully crystallise sufficiently by the end of March to be submissible for VisWeek 2011. Cross yer fingers.

Today’s backyard time management section is in fact more about planning than it is about notes. However, my Pro-Tips involve combining them in an easy to implement productivity booster. When people start out in research, one of the first bits of advice they get is keeping some kind of lab journal. I think this advice applies to more than just research: If you do any kind of independent or project work, jotting down your activities, thoughts and results during the day is useful in helping to structure your thought processes, and also very helpful when you have to backtrack a complex multi-day procedure. During my Ph.D., I filled a number of real cardboard-and-paper books with notes. More recently, I’ve started using Google Documents for the same purpose. Besides all the other advantages, having to document explicitly your work output keeps you productive and on your toes.

Pro Tip #1: Keep a lab journal, even if you don’t work in a lab.

I’ve mentioned before that my resolutions for 2011 included more concrete planning. This has manifested in a work-in-progress planning for the whole year, including milestones, awards won, and so forth, but much more practically, it has manifested in a little lab-journal-compatible trick. Every morning when I sit down to begin the day, I spend a few minutes thinking and then start the day’s journal entry by writing down, as concretely as possible, the tasks that I plan to complete by the end of the day. This also ensures that I spend effort on the important things, and not only on the urgent things. So, that brings us to:

Pro Tip #2: At the start of each day, write down in your lab journal exactly and concretely what you plan to accomplish by the end of that day.

These pro tips appear to be quite straight-forward, but together they help one to focus, and to keep tabs on one’s effective productivity. In other words, just being terribly busy the whole day gets you nothing; the trick is being terribly busy in all the right directions.

P.S.

Somebody is clearly pushing the boundaries of awesomeness… cowboys AND aliens!

Sometimes, being in academia rules. [Weekly Head Voices #25]

Kids!  It’s now truly summer over here, which means as much as possible time outside, which means less time available for writing blog posts. However, weeks 24 and 25 of 2010 contained such newsworthy items, that I’m simply forced to trade some sun-light for a bit of TFT exposure. In this post, we talk flowers, PhD defences, scientific talks, funny Js and finally stick figures, so please stick around!

I took this photo of the Oude Kerk in Delft as we were taking a walk with one of our esteemed guests. So it's really relevant to this post, ok?

Last week we had our department’s yearly BBQ at the Blue Lagoon at Scheveningen.  In a not altogether surprising turn of events, I’ve been working at the TU for 10 years, and I now have the bunch of orange flowers to show for it! Time is really fun when you’re having flies.

Five of my MedVis (that’s IN4307; if you’re at the TU, make sure you take this life-changing course! :P ) students presented their final project work. Between the visualisations of coronary stents from optical coherence tomography data, the 3D lung volume reduction surgery (LVRS) planning tool and the real-time X-Ray simulator, I was hugely and pleasantly impressed.  Expect to see a large part of this functionality in a future release of DeVIDE. This was energy-producing event #1 of the past two weeks. Energy-producing event #2 was a M.Sc. defence that I opposed just this past Friday, where the candidate presented and defended, in a highly-entertaining and convincing fashion, his thesis on investigating 3D synthetic aperture radar construction on multi-core architectures.

Energy-producing event #3 was when the now freshly minted Dr Eric Griffith defended his PhD thesis on Visualizing Cumulus Clouds in Virtual Reality in stellar fashion.  Dr Griffith did a superb job of maintaining an eloquent discussion with all 7 of his opponents. The offence of Prof Jos Roerdink (Visualisation, Groningen) also deserves mention: The multi-level questions and typically professorial delivery were most entertaining.

The final energy-producing event that I’m going to mention has been named #4 for mysterious reasons, and, for other reasons that will soon become clear, was for me the most significant. Jorik Blaas, close collaborator and friend for the past seven (7!) years, defended his PhD on the Visual Analysis of Multi-Field Data, on Thursday June 24. To take part in the offence, we were extremely honoured to welcome three luminaries of my research field (that’s Visualisation, for those of you who’ve just joined!): Prof.dr. Jack van Wijk, Prof.dr. Anders Ynnerman and the Viennese-Bergenesque Prof.dr. Helwig Hauser. Having all three of them in Delft was just WOW, you just have to trust me on this. In any case, for the first time at the TU, I was also allowed to take my place in the PhD committee. :)

Of course, Dr Blaas sailed through the defence, his usual understated yet verbally effective hyper-intelligent self. Invited lectures by our guests, much late night discussion on the nature of (visualisation) science and of life in general and finally a PhD party that stress-tested all glandular resilience helped to turn this into one seriously wonderful and life-affirming week. I am thankful to all involved.

In completely unrelated news:

  • Have you ever wondered what that funnily isolated ‘J’ character is doing at the end of sentences in emails?  Well, wonder no more! (5-second-version: it’s supposed to be a smiley, but Outlook on the sending side substitutes it with a character from the Wingdings font that is rendered at the receiving side, if that font is not available, as a ‘J’)
  • My 4-year old daughter recently made a drawing with two stick figures standing next to each other. Not significant as such, but the one stick figure was wearing a bow tie, while the other stick figure had a thought bubble above its head with a bow tie in it.

Thank you for joining me again for this edition of the Weekly Head Voices, and please feel free to kick-off completely unrelated discussions in the comments.  Next week (actually this week, I’m late), four of us will be going to Leipzig for the bi-annual Eurographics workshop on Visual Computing for Biology and Medicine (VCBM), which I’ll probably be reporting on in a future blog post (and hopefully on twitter with hashtag #vcbm2010). Stay tuned for much fun and excitement!

Augmentation [Weekly Head Voices #23]

(This edition is about babies, textbook Ph.D. defences and mind-viruses in Snow Crash, all of which can mostly be filed under backyard-philosophy(ish).)

On the theme of striving for The Next Level, my not-quite-1-month-old bundle of joy laughed out loud today for the first time! I’m sure that it was not a false alarm, as I was being my usual comedic genius self (I target the 1 to 3 month-old crowd), and the pattern of stimulus and reaction was just too well-coordinated and sustained to be coincidental.

On the theme of really cool events, on Thursday I had the privilege of being part of the Best Ph.D. Defence EVAR. Seriously people, the day that my good friend Frans Steenbrink became my good friend Dr. Frans Steenbrink will pleasantly resonate in my mind for a long time to come.

A typical scene during an average Ph.D. defence. The candidate is in the middle, surrounded by committee members on both sides. At this very moment, he is investigating two possible lines of argument.

Here in NL, a Ph.D. defence is a fantastic affair: The candidate has to defend his work against the highly-experienced offensive mental manoeuvres of a committee consisting of around 7 wise men, most of them grizzled veteran professors who have eaten many a hapless candidate FOR BREAKFAST! As if that weren’t awe-inspiring enough, the defence usually takes place in some imposing building, preferably more than a few hundred years old (in this case, it was the Academiegebouw in Leiden, almost 500 hundred years old), the committee are in full academic (read: battle) garb, and the whole affair is public, so the candidate is joined by a potentially sizeable audience. Believe me, this can be a nauseatingly stressful experience.

Of course Dr. Steenbrink handled the whole affair with elegance and, extremely unusually, a healthy dose of humour. It might be the first time that I’ve ever seen a candidate disarm his opponents not only by artfully responding to their questions, but with an ever-so-slightly irreverent injection of humour. It was beautiful.

After the successful defence, we were all picked up by a boat and taken via the Leiden canals to De Poort for the after-party, and what an after-party it was… Besides the live performance of Frédérik Steenbrink, the two electro DJs, the superb saxophonist who was able to accompany them musically (!!!), the Louis Theroux-style documentary put together by Mr Cricket, and copious amounts of free beer, it was positively life-affirming to see the Master of Good Karma (the freshly minted doctor goes by many names) being surrounded by his Karma-children, all emanating. You need to know him in order to understand this completely, but you have to trust me that it was beautiful.

On the theme of understated super-heroes, I finally got around to reading Neal Stephenson’s Snow Crash, triggered by a Cosa Nostra t-shirt shown on boingboing. I know I know, I could have lost my Cyberpunk Nerd membership card for only reading it this late in my life…

In any case, I really enjoyed the book, especially for the characters (the protagonist, called Hiro Protagonist, is naturally a half-African American half-Korean hacker / sword-fighter / pizza delivery guy), the far-out society (the world is run by private franchises, amongst others the Mafia, owner of the extremely influential Cosa Nostra pizza chain and run by the charismatic Uncle Enzo), the crazy technological artefacts (the Rat Things!) and for all the changes in society brought about by the crazy technology, not least of which the Metaverse. The Metaverse is the name Stephenson gave to his extrapolation of various phenomena present or considered in 1992: The internet, virtual reality, Gibsonian cyberspace. The protagonists spend a portion of their time not quite jacked in, but with augmented reality goggles and high-fidelity ear-phones, walking around as avatars in an artificial world with a total population of slightly less than what facebook has now, if I remember correctly.

Personally, I didn’t find Snowcrash quite as good as Gibson’s Neuromancer (see my 2003 ode here. it still gives me goose-flesh…), but somehow, very sneakily, it has still managed to manoeuvre itself into my list of all-time favourite books.

The story is built around the interesting idea of a neuro-linguistic virus, that is a certain sequence of sounds that is somehow able to get into the human deep brain, screw things up royally and spread through verbal contact with other humans. It has a cyberspace equivalent called Snow Crash: If programmers in the Metaverse see this specially coded binary image (through their AR interfaces), their brains essentially crash and they’re turned into vegetables. It’s all very complex (see this wikipedia page) and quite far fetched, but the idea of considering certain large-scale social phenomena as a kind of mind-virus, that is a potentially damaging entity that integrates at very low level with its host, is self-replicating and is able to spread to other humans, is intriguing to say the least.

Recall that Dawkins partly coined the by now well-known English term “meme” in his 1976 book, The Selfish Gene, as it turns out that the concept was more or less first written about by Semon in 1904. A meme, analogous to a gene, is an element of social information, for example the mistaken idea that going outside in cold weather increases the chances of getting a cold (in this case, not true, but still a meme). Analogous to a biological virus, a mind-virus would then be built up from various memes. Each meme would take care of a different function of the mind-virus, helping to guarantee its survival and proliferation throughout humankind, for example: Don’t question me (meme1), believe in me (meme2), spread me (meme3), be exclusively faithful to me (meme4), do this or you will be severely punished (meme5), do this and you will be greatly rewarded (meme6).

If you’re wondering what I mean by all of this, rest assured in the fact that Zombo Com has all the answers.

Kids, now go and have yourselves a fantastic week!
