For months I’ve been walking around with this idea in my head. I was planning to turn it into a blog post titled “On not scaling”. It was going to be about deliberately choosing focus over bandwidth in one’s activities. One is often faced with the choice between scaling up (more work, more people, more things, more turnover, more for the sake of more) on the one hand, and simply not scaling on the other, instead holding on to one’s simple and linear way of doing a few things well. The former approach seems to be the one favoured and encouraged by modern society. The latter has become my preference.

We’ve all been there.

Faced with a daunting and complicated project (thesis, book, building a house, the list goes on), or a whole bunch of projects, you start suffering from an acute sort of brain deadlock, freezing like an antelope in the headlights of the rapidly approaching deadline pick-up truck, yeehawing redneck behind the steering wheel.

Perhaps even worse than the freezing, is the procrastination. You somehow manage to start moving, except that you’re pouring all your energy into everything but the work that you actually need to do. You manage record numbers of facebook / twitter / google+ posts, and you attain mastery of coin-knuckle-rolling (marketable skill #1), but the day ends with you having made no further progress.

After many great years in academia, I finally decided in October of last year to resign from my position as tenured assistant professor. As of February of this year, I proudly walk the earth as an independent engineer.

It has taken me two years of thinking to reach this decision.

I started re-evaluating my life in academia two years ago after a review-for-promotion (See the “oral defence” bullet. :)) process that resulted in a “not quite yet” judgement. It took this long to make my decision, because it was actually going quite well. I had tenure, the holy grail (well, the first of a number of them) for many academics. I had built up and was heading the TU Delft Medical Visualization research group. I was fortunate to attract the best postgraduate students and Ph.D. candidates. My research proposals were successful, so I had money to explore exciting new research avenues. My h-index was (slowly) going in the right direction. Even my teaching was more than occasionally positively received. :)

Dear readers,

I will soon be starting a new life adventure. In fact, maybe even two of them. Hence, there is a significant probability that this weblog will again be updated more frequently in 2013.

Also, I have just changed the email and RSS subscription system:

• If you were subscribed via email, please subscribe anew via the subscribe button to the right. If you still receive emails from feedburner concerning this blog, please unsubscribe using the instructions in those emails. The idea is to stop using the feedburner email subscription (which was active for the past few years) and to start using wordpress.com for this (the new system).
• If you were subscribed via RSS reader, double check that your feed address is http://cpbotha.net/feed and NOT anything to do with feedburner anymore. The feedburner feed should redirect to my own feed in any case.

I hope that you have a fabulous vacation, and a happy and healthy 2013! I look forward to seeing you then.

There are many similarities between startups, defined here as (relatively) young and agile companies with a few bright people trying to change the world by working on some cool idea(s), and academic research groups, defined here as (relatively) young and agile units within academic institutes with a few bright people trying to change the world by working on some cool idea(s). Err, yes.

Fortunately there are also many differences, so I have something to write about here. For some years now I’ve been running the TU Delft Medical Visualization research group, an experience that shall serve as the primary source of information for this piece. I’ve also had some experience of startup culture, first as one of two (and later three) engineers in a new business unit of Crusader Systems (now CSense) designing an embedded image processing product called FrothMaster, then at Stone Three as employee #1, then later at Treparel as a co-founder and architect, and more recently as scientific advisor to Clinical Graphics and co-founder of TimeScapers. In spite of this healthy dose of exposure, I’ve never actually run a startup as my main activity, so I will have to extrapolate and sometimes revert to wild guesses. I am trusting that some of the startup-involved readers will pipe up in the comments!

When I acquired my pre-ultrabook-era but still pretty Samsung NP300V3A laptop some nine months ago, I lamented that I’d probably never be able to put Linux on there due to the NVIDIA Optimus graphics switching thingamagoo.

Well, yesterday I ate my hat.

If you have nerdy tendencies, head on over to VXLabs, my nerd blog, to read all about it.

I’ve been a Dropbox Pro (50G) user for more than two years now, and in this time it has never let me down, not even by a little bit. Still, when Google announced its new Google Drive syncing service, I had to take it for a spin.

For those of you with short attention spans, my conclusion is: Google Drive has great promise due to its price-point, Google’s great infrastructure and the integration with Google Docs, but you shouldn’t yet trust this service with your critical files.

The rhythm of life

I love Unkle. Here’s the introduction to their song Back and Forth:

The only life you can get is one made up of ups and downs. The trick is in learning how to deal with the downs, increasing the number and duration of the ups, and enjoying every last drop out of them. This realisation was brought to the surface by a car advert in which the narrator claimed that time in the car equalled “quality time”. I don’t like cars, but I love quality time. It usually comes in little bits and, as I’ve reported before on this very blog, happiness and other important things also come in little bits, interspersed by other often less interesting bits. Although one has a limited extent of control over some parameters of this rhythm of ups and downs, of excitement and boredom, it can never be smoothed out. As is often the case, the best course of action is the zen one: Step outside and try to absorb completely the multi-factorial whole.

I’ve been dealing with a spot of blog writer’s block, hence the lateness of this post. I’d forgotten that these monthly instalments were initially intended to be extended status updates, with a spot of backyard philosophy every so often. Trying to come up with worthwhile backyard philosophy every week is just plain hard. This week I’m going for half a status update along with a list of possibly interesting sciencey tidbits.

I’ve spent days writing this post in my head, and now it’s taken more than two weeks to get done. It’s not that I have something complicated or difficult to tell you, it’s just that I was privy to three absolutely awesome weeks of vacation in an undisclosed location to the very far south of my current coordinates, during which I attained ultimate levels of relaxation that caused my brain to shut-down large parts of itself. The only parts that managed to remain online were those dedicated to slow living, appreciation of people and surroundings and, finally, deep thought. My brain is currently taking its sweet time to come fully online again.
