Weekly Head Voices #11: iCalmDown.

January 31st, 2010 · life, science, work

My Tall Philosophical Neighbour (henceforth TPN) blogged today about the iCalmDown, which, as you know, is the latest Apple product released with perhaps a tad too much fanfare this past week. Yes, I do realise that I’m most privileged to have a tall neighbour who’s both philosophical and manages to blog with more regularity than many. In any case, in a cut-and-dried case of keepin’ up with the Joneses, or the TBN in this case, you are now holding in your hands the eleventh edition of the Weekly Head Voices, documenting a selection of events taking place in week 4 of 2010. Please let me know if you’re reading this on your iCalmDown!

SuSE engineers consider this dog to be "quite pretty" and also "so cute and cuddly".

First I have to get some negative emotions off my chest: I’m currently test-driving the TU Delft’s new standard SuSE Enterprise Linux Edition (SLED) 11 image at work. After two days of using the system and documenting my experiences, I had to switch back to my usual Ubuntu desktop, as my eyes had started bleeding profusely. The SLED desktop takes the concept of “ugly” to places even it feels very dirty having ever visited. Okay, so I might be ever so slightly exaggerating, but there really is almost no comparison with a modern Ubuntu system!

During this past week my productivity has again made the transition from reactive to proactive. This is a usual phenomenon after any long vacation, but it sure is a nice feeling being able to start on things long before they become urgent. It gives me some room to strategise and think about the Big Picture. In the same vein, I (once again) realised that I should spend mornings on the creative and heavier-weight items on my todo list, and reserve the afternoons for meetings (which definitely require creativity, but of a different kind) and more routine tasks. For the past months I have followed the policy of scheduling meetings in the afternoons as far as possible, so my mornings are reserved for tasks that require a few hours contiguously. Luxury!

At the start of an evening with two friends (in line with my anonymisation policy, let’s call them Science Entrepreneur Friend, or SEF, and Extremely Clever Yet Very Social Scientist Friend, or ECYVSSF) that ended with me having so much fun that I managed to get caught on the infamous Dutch nachtnet (trains that take party-goers home at ungodly hours), SEF pointed out that my “to learn and to create” snippet of the previous post reminded him of something of Wilhelm von Humboldt. After some searching I found the relevant quote:

To inquire and to create;—these are the grand centres around which all human pursuits revolve, or at least to these objects do they all more or less directly refer. Before inquiry can fathom the very essence of things, or penetrate to the limits of reason, it presupposes, in addition to profundity, a rich diversity and genial warmth of soul—the harmonious exertion of all the human faculties combined.

Thank you SEF !

This same evening was characterised by, besides too many Pelgrim Trippels (a strong beer brewed in Rotterdam), much heated discussion on the interaction between science, that is how we attain and disseminate new knowledge about the reality around us, and academia, that is the interesting ecosphere where science mostly takes place, where scientists work in strange and strict hierarchical castes, and the focus on science can easily be lost due to the practicalities and politics of academia.

For all its faults, it is exactly this strange system that makes it possible for me to work closely together with a number of exceptionally bright people, an energising activity that is arguably very much in the spirit of inquiry and of creativity.

On that positive note, have a brilliant week everyone!

Weekly Head Voices #10: Loose bits sink chips.

January 24th, 2010 · life, nerd, work

HI THERE KIDS!

You might have thought that my Weekly Head Voices were a thing of the past, but I unfortunately have to disappoint you yet again. The weekly head voices will continue in 2010, in spite of slip-ups like this one, where I’m going to have to stuff three weeks of inconsequentialities into the room usually reserved for a single week of inconsequentialities. Whatever the case may be, welcome to this edition, covering weeks 1, 2 and 3 of 2010!

A fine day in beautiful Bergen, on our way to have lunch.

In week 1, I had the privilege of visiting the University of Bergen in Norway, where I opposed the defence of Jean-Paul Balabanian, now the proud owner of a successfully defended PhD thesis on integrated view visualisation. Dr. Balabanian proposed, based on a number of solid publications, that integrated views, i.e. the idea of creating a single visualisation combining a number of different conceptual views instead of making use of separate coupled views, is in many cases more effective. Making the acquaintance of Prof. Christof Rezk-Salama, my co-opponent, was an added bonus on top of catching up with the Bergen crew.

On the Big Brother front, I have started using the Dutch OV chipkaart also for travelling by train. The OV chipkaart is a single smart card with which one will eventually be able to pay for all shapes and forms of public transport in the Netherlands. The cool thing is that one can in theory travel more efficiently as no tickets have to be bought. As one is diving through the closing doors of the train, one waves the card past a conveniently placed reader and the system records the station whilst also deducting a deposit. As one leaves the train at one’s destination, in a slightly more relaxed fashion, one elegantly waves the card past yet another conveniently placed reader, thus checking out and having the unused part of the deposit transferred back to the card.

This usually, surprisingly, works. The other day however, my diving through the closing train doors resulted in the waving not being properly registered, resulting in my NOT checking IN and hence mistakenly checking IN at my destination, instead of OUT (it’s the same card reader). Checking out immediately in order to undo the whole operation was problematic, as the system kept claiming that I was already checked in. Whoops. Much later, i.e. after I had lost my deposit, it turned out that one has to wait for 2 minutes before being able to check out again. Remember that kids, remember that. You can buy me a deposit’s worth of beers when we see each other again.

My SO now owns a brand-new iPhone 3GS. It is indeed a beautiful thing, but the beauty unfortunately does not make up for the on-screen keyboard, or rather the lack of hardware qwerty keyboard. This has made me rethink my plans to get the similarly keyboardless Google Nexus One when it’s officially released over here. I’ll wait for the first Nexus One-class phone with a good keyboard. Reviews have unfortunately not been kind with regard to the Motorola / Droid keyboard, so I’m going to skip that one.  (There is that other nagging little issue that it looks like a brick. A brick with a slide-out sub-standard keyboard. It is indeed a very smooth brick. If one were to build a house with it, it would indeed be a very special house, if a tad expensive.)

On the work front, I have two bits of incredibly good news:

  • After spending significant time on finishing my teaching portfolio (just call it a mini-thesis) last year, I am now the proud owner of a TU Delft BKO, which means that I’m qualified to teach at University level, using all kinds of new-fangled learning methods. Note that I said “learning” and not “teaching”. This means I’m hip. If you see me lying outside under a tree with one of my classes, you know we’re Learning, with a capital L.
  • Our STW NIG proposal “Novel pre-operative planning and intra-operative guidance system for shoulder replacement surgery” has been approved! We now have enough money to pay two people for 4 years to work on our Top Secret NEW Idea for surgical guidance. This proposal was written together with colleagues from the LUMC Department of Orthopaedics.

On the same front, I made the depressing mistake of calculating my h-index the other day.  Publish or Perish, great little tool that it is, has difficulty with my very common surname, plus that it misses some of my oldest publications that have the highest number of citations, and Scopus is just too durn stingy, so I rolled my own quick and dirty hack that parses Google Scholar with BeautifulSoup, based on a RIS-format list of my publications. Whatever the case may be, the outcome was mildly discouraging. I believe the “h” in h-index stands for “HARSH”. Harsh man!

In the meantime, I’ve mostly recovered by remembering (or rather being reminded by the observant folk around me) that I started doing what I do not to work on my probably doomed h-index, but to learn and to create. This indeed still makes me happy.

That being said, YOU CAN START CITING OUR ARTICLES NOW, PEOPLE!! :)

The 2009 to 2010 transition post.

January 10th, 2010 · life

Holiday feeling.

Yes, that up there is my foot. Next to my beer. On my balcony. Overlooking my ocean and my clouds…

It was a ridiculously lovely holiday, with the only drawback that I wasn’t able to take more people along on it. Fear not, soon my Master Plan will come to fruition, in which my significant other will become famously rich and I’ll be able to charter a Family and Friends Boeing (or an Airbus, depending on the rules that govern such things at that time), and you’ll all be able to tag along on my Ridiculously Lovely holiday. Fear not, for I will not forget you.

2010 is now upon us. This year, I plan to create value, in as many ways as I can. I have resolved to meditate more often. I have also resolved to spend more time on meaningful communication with friends and other appreciated humans. May you have exactly the year that you desire, or the one that you need.

Three rules of stress-free email productivity

November 29th, 2009 · life, work

Hey kids, this would have been the Weekly Head Voices #10, but since the past week can be really compactly summarised (4 hours of lecturing, 8 hours of lab supervision, 1 M.Sc. defense, 15 hours of meetings, 1 brilliant going-away party), I’ve decided to dedicate this week’s post to something completely different, something that one or two of you might even find useful!

I get to process quite an amount of email every day, and the amount seems to be increasing year after year.  Experience has taught me one or two hard lessons with regard to the efficient handling of said email.  Because I like you, I now give you my not-so-secret-anymore rules for stress-free email productivity!

1. Only check email when you actually have the time to take action.

This is the most important rule, and also the one I forget the most often.  The bottom-line is that you should only check your email if you have the time and inclination at that moment to take action on all of your inbox.  Taking action includes the GTD-style delete, delegate, defer and do possibilities, so for example chopping an email up into its constituent actions and sticking those in your todo-system (deferring) counts as taking action.  Under any other circumstances, don’t even check, as this will only serve to stress you out.  Conversely, following this rule will lead to having longer blocks of contiguous time to spend on tasks that you select, and not the crazy reactive work processing style endemic in the modern work place.

This rule is in practice nicely satisfied by the advice to make time for two or three distinct email processing moments per day.

2. Don’t use email as your main todo system.

Conversely put, have a good todo system that’s separate from your email.  This forces you to analyse emails during email processing moments and to break them up into the atomic GTD-style tasks that they represent.  You can always link the original email to the task, but the task description should be your main unit of work.  Seeing the same emails over and over increases stress and leads to unnecessary effort as you analyse them again and again every time that you see them.  Tasks, in general being more concisely described, are easier to start with and also increase the resolution of your accountable productivity.

3. Have separate work and non-work accounts.

Accidentally seeing one work email during your well-deserved holiday can spoil your mood. Maintain a separate email account for non-work (social) matters and make sure correspondents are aware of the difference.  This way, you can continue using email during rest periods without the risk of that one misplaced email putting you back in work-mode for the rest of the day.  This measure helps to maximise the value of your relaxation time.

Following the three rules above will also help a great deal in attaining and maintaining the nirvana that is inbox-zero.

Weekly Head Voices #9: Windows 7 Geek-o-Rama.

November 23rd, 2009 · life, nerd, science, tech, work

I’ve unfortunately not been involved in any quantum entanglement accidents recently — teaching duties are mostly to be blamed for my two-week silence.  Besides spending at least a whole work-day every week on our Data Visualisation practical, I’ve been lecturing and also been preparing a new lecture block on information visualisation with a dash of visual data analysis.  Due to my not secretly being an infovis expert, this latter activity has taken up quite a chunk of my time and effort.  On the other hand, the exercise has forced me to acquire a significant amount of new infovis brain juice which I’ll probably soon be applying to impressive effect.

In any case.

On the geek front, I have to say that I’m really liking Windows 7.  Partly eye-candy, partly the SuperBar, partly the revamped file manager: I’m a happy camper both on the NetBook (just installed 4GB of SDHC especially for ReadyBoost) and on the quad core workstation.  Feel free to discuss this in the comments, even, or especially, my black turtleneck-wearing friends! :)   Unrelated to the big 7, it turns out that if you use large removable (USB) drives between computers with different operating systems, NTFS is your best bet.  Even more unrelated, I’ve also discovered that one can implement complete independent Windows applications using AutoHotkey.  Before I knew what I was doing, I had re-implemented most of my envedit application in AutoHotKey, with GUI and all (you can find my efforts in SVN, AHK’s a strange little language).  The resultant stand-alone app is 400k, which compares favourably to the 4MB envedit installation.  To conclude this week’s edition of I Really Like Geeking Out, I broke down and bought 20G of extra Google storage for slightly less than EUR 5 per year.  I’m not using it (yet), but I somehow get a kick from seeing this at the bottom of my GMail interface (click the image for a slightly larger version):

With regard to research, things have been going just swimmingly.  There are a number of really cool articles being lovingly incubated as we speak.  Some mathematical visualization and some time-varying VDA will go to Eurovis, whilst one other submission is already being carefully groomed for the Vis deadline in March next year.

In other news that absolutely made my day on Monday, November 9, 2009: After being in the oven for almost two years, our pathological shoulder segmentation article should soon appear at a news-stand near you:

Peter R Krekel, Edward R Valstar, Frits H Post, Piet M Rozing, and Charl P Botha. 2009. Combined Surface and Volume Processing for Fused Joint Segmentation. The International Journal for Computer Assisted Radiology and Surgery.

Mr Cricket, that was just marvelous!

Finally, I’m ecstatic to report that due to an unfair dose of serendipity, not in the least brought about by the involvement of one extremely resourceful individual, Longitudinal Medical Visualisation (google should take you to the right place) looks like it might be getting off the ground in a Really Big Way soon.  Stay tuned kids, stay tuned.
