Coffee addiction potpourri. [Weekly Head Voices #57]

Yes boys and girls, I was keeping back writing that Rebecca Black post, but now it’s 4 days later and I can let ‘er rip again, like I promised. This week’s post sort of reflects my week 37: Chock-full of super-dense life nuggets. Hmmm, sounds like a brilliant new high energy meta-physical chocolate bar that would probably be immediately declared illegal by the current conservative and non-thinking (excuse the tautology) batch of spineless politicians (excuse the tautology).

Let’s get today’s life lessons started with Mitch Hedberg, Comic Genius (note the captital C, and the capital G):

Hedberg’s genius unfortunately could not save him from drug addiction and his overdose-related death in 2005.

On the topic of addiction, fpixel forwarded these new findings that coffee drinking is genetic, both in terms of capacity and perhaps also in terms of addiction. Even my atoms are addicted to coffee, so that feels about right. What’s really interesting however, is that the documented study found that the genes involved in the metabolism of coffee (CYPIA1 and NRCAM, if I understand correctly) are also related to the onset of Parkinson’s disease. You see, coffee drinkers are less prone to Parkinson’s disease (as well as a whole list of other diseases including prostate cancer, type 2 diabetes and liver cancer). However, past studies of course show correlation and not causation, i.e. coffee drinking and low risk of disease X appear together, but that does not tell us anything about what causes what. This new study has made the first steps towards understanding the mechanism that actually links Parkinson’s disease and coffee drinking.

On the topic of coffee and addiction, TNR and I spent the Monday morning working (like animals) on our new parallel startup (there, I said it) at the Coffee Company in Delft. Two things:

  1. The Coffee Company makes a killer cappuccino. The milk is steamed to perfection, but it’s got the perfect espresso bomb exploding through all that milky goodness at just the right moment. BAM! HELLO THERE! Highly recommended. With every purchase, you get WiFi access for one hour, so no surprises or misunderstandings.
  2. It’s amazing what such a change of working environment does for one’s creativity.

On the topic of startups, Dr Jorik Blaas, ex PhDer, full-time genius and friend, is now the director of research and development at Synerscope (probably no relation with sinister, but my subconscious is just not behaving today), a high-potential startup that makes visualisation-based tools for fraud detection in big data (big money, IOW). Synerscope has brought together some of the top visualisation brains in the country. Personally, I can’t help but imagine it like this:

Are you in there somewhere?

On Tuesday and Wednesday, we made a quick train trip (*cough* 9 hours there due to delay thank you NS, 7+ hours back) to Magdeburg for the bi-annual German MedVis meeting. You’ll recall that I spent my first micro-sabbatical there. The city almost feels like home, and it was really great seeing many of the Magdeburg peeps again. The meeting itself was of high quality, with a number of VisWeek contributions being presented. Thomas Kroes (should I start using fictitious names and acronyms again?) presented his interactive photo-realistic volume renderer too! By the way, download it, use it (it makes fantastically beautiful renderings), spread it, and do cite the soon-to-appear article.

On Saturday, it rained (again, or still, I forget), so I decided to flip Mother Nature the bird by BBQing four juicy rib-eye steaks outside. Take that Mother Nature! The steaks were delicious, thank you. Mother Nature is not all bad though… Check this out: The Southern Lights. FROM SPACE!

I’m going to wind down this post with two backyard philosophy-themed bits. The first is a quote by mathematician Alfred North Whitehead from this article on “The Skill that Matters Most” (found via Joe Botha, serial entrepreneur, currently changing the world with Trust Fabric):

Civilization advances by extending the number of important operations which we can perform without thinking about them.

I haven’t thought about it that way before, but it does make complete sense. The more things we humans do well in a routine fashion, the better.  Otherwise, our inconsistency is prone to lead to problems. By the way, the mentioned skill is self-control.

Finally, AJ forwarded this video called Disconnect to Connect. I’ll just let you watch and think about it for a while:

I’ll be off now. Please do have an epic week, and think of me when your level of enjoyment is at a local maximum. At these points, you might also consider jumping around randomly.

Rebecca Black is OK! [Weekly Head Voices #56]

Probably the most brainless song on the whole of YouTube must be “Friday” (don’t click that link, please) by Rebecca Black. At one stage, she’s seriously singing about leaving home and going to the bus stop on Friday. As if that’s not mentally taxing enough for her, her friends arrive in a car, and, wait for it, SHE HAS TO DECIDE IN WHICH SEAT TO SIT. Heavens. Talk about broody teenager angst. DANGIT I MISS GRUNGE!

In any case, I was convinced that Rebecca Black was a portent of the end of the world as we know it, probably due to an unstoppable tsunami of vacuous stupidity crashing through the whole of civilization (you have to admit, there are signs. what signs? well mostly politicians and managers). However, due to a recent instance of such blinding brilliance that I had to don my mental steampunk goggles of total darkness (yes, the ones I’ll be wearing to Burning Man when I go there), I have to revise my opinion of Rebecca. You see, her musical atrocity has acted as a catalyst for the creation of the musical masterpiece that is Braaiday! Seat yourself comfortably, and experience it:

Yes? Yes. Hang on while I listen to it one more time. No I don’t need YouTube anymore, the whole thing is engraved in my brain. By the way, September 24 is National Braai day in South Africa. You know what to do…

As if Braaiday wasn’t enough to make my year, TNR, friend and business partner, underwent two significant life events:

  1. He turned a year older.
  2. The day after his birthday (doh), TNR was offered an assistant professorship in our section!

We’ll leave the consequences of life event #1 for a later, more philosophical, occasion. The consequence of #2, together with the fact that we’ve somehow managed to attract a handful of Truly Kickass people (you know who you are, kickass people!), is that there’s now an absolutely fabulous vibe in our research group. I’ve had the privilege of experiencing this specific vibe in other places before. You can’t engineer it, it simply has to happen. The best you can do, is to put the right people together and cross your fingers. When it does decide to appear, it’s epic!

On a different topic: The reason why I’ve been ignoring all of your email the past weeks, and why I generally haven’t even been able to pay attention to the beautiful wooshing sound all of my passing deadlines made as they flew by, is because I was first preparing for and then running, together with a whole team of ninjas, the TU Delft CS first year introductory project. I designed this brand-new module last year, and severely honed it this year. 130+ first years worked together in 26 small groups designing and implementing augmented reality music instruments with real-time video analysis, 3D graphics and sound loop mixing. CACOPHONY with a capital C!

I’ve uploaded to YouTube some video impressions of the top teams demonstrating their projects in the concluding session. Click here to view these and any other clips that other peeps have tagged with “ti100a” (the course code).

OK people. That was it for weeks 35 and 36 (this post was 100% produced within moving trains!), the week 37 blog post will hopefully appear this weekend sometime. I’m still Way Too Busy (do you hear that wooshing sound in the distance too?), but managing to keep myself quite happy by:

  1. ensuring that most of the time I spend, I spend creating value;
  2. ensuring that the people I interact with are primarily of the ass-kicking variety;
  3. making many bullet lists like this one.

See you on the other side!

P.S. Have you heard about batmanning? Apparently it’s the new planking:

Taxing but fun. [Weekly Head Voices #43]

With every edition I claim that I have no time to post, but this time, I have even less time than usual. However, here I am to bring you a super-duper compact time-saving edition of the Weekly Head Voices, filled with the highlights of week 12 of 2011. I’ll start this edition with some church:

Pretty spring photo of the back of the New Church in Delft, taken whilst I was waiting for my guest (Our Man in Vienna, temporarily in Delft!) to exit his hotel.

  • I’ve tried to give you a more snappy blog loading experience by installing the WP Super Cache (with a 24 hour site preload), DB Cache Reloaded Fix and Use Google Libraries plugins. In many cases, you’ll get served a static HTML page, which is much faster than the on-demand SQL-spewing PHP-generated complexity WordPress usually does. In the great big quagmire that is WordPress caching plugins, this combination seems to be working best in my case. Measuring with tools.pingdom.org (awesome resource!), most of the pages on this site should now fully render in around 2 seconds.
  • The TNR and I souped up the work website, it’s looking really spiffy now, with embedded RSS feeds and all!
  • I’ve finally installed JuiceDefender on my laptop with built-in telephone (my HTC Desire Z smartphone, in other words), the battery almost lasts the whole day now! If you have an Android telephone and your not happy with your battery life (err, is that even a question?), get this app. Now.
  • I opposed an M.Sc. defence on Tuesday on the ultrasound measurement of tendon displacement in vivo and subsequent derivation of moment arms. Great fun diving into new work like that! The student did a great job.
  • Our Man in Vienna came to visit us in Delft. Huge fun was had by me and Our Man in Vienna (I hope), and serious work was done. It’s a great combination, we will attempt to apply it more often.
  • On Friday evening I slipped and did our yearly tax return by accident. BAM!

This is the end my friend. Here’s some more church (a different one, at least), taken after a scrumptious dinner in the city:

The Old Church in Delft, with pretty lighting. This is not a simulation.

Have a great week everyone! Over here, we’ll be chasing deadlines, and many of ‘em. WATCH OUT YOU DEADLINES!

Drown in the now. [Weekly Head Voices #42]

Carrying the portentous number 42, this edition of the Weekly Head Voices owes it to the sometimes nerdy expectations of its readers to offer at least a small part of the answer to life, the universe and everything. In other words, #42 is 100% backyard philosophy.

Water, and bridges, and paths, taken this morning especially for you. You should start feeling all pensive now.

I’ve had a really brilliant week. When it started, one of the slightly more zen voices in my head proposed a little experiment: What would happen if, at the start of every episode or moment that I found myself in, I would consciously and explicitly remind myself to be fully and exclusively in that moment, to focus on the now. I could only agree that this was an intriguing question, and one worth attempting to answer.

The hardest part was remembering to do this every time. However, once I managed to get past that hurdle, the seemingly simple and low-level act of sub-vocally reminding myself to dedicate my undivided attention to the moment currently at hand resulted in more and more sustained periods of focus, which gave each situation, even the seemingly straightforward ones and especially those involving social contact, significantly more depth. It was almost like flipping a big bass boost button on my daily experiences, with all primary and secondary senses arriving in glorious multi-dimensional technicolour.

If your brain is like mine, constantly shooting off in five different tangents at the smallest instigation, I can only recommend this self-reminder trick. There are other times when such tangents are useful and should be stimulated, for example during planning or creative sessions, but more often being fully in the now is what you should go for. This goes diametrically against the grain of our evolved information foraging compulsion and the associated multi-tasking (that we turn out to be really bad at), but is worth the mental effort many times over.

I’ll end this short post with a musical conclusion:

YouTube Preview Image

Drown in the now… A beautiful and apt title for a song with some of the most spacy lyrics you’ll come across, at least until the next time you do some Crystal Method.

Kids, have an awesome week, filled with pure Now.

p.s. Jorik, in an uncontrollable attack of the WABs, just pointed out a spelling mistake in this post. It’s portentous, and not portentious. :)

Spring has arrived in suburbia! [Weekly Head Voices #40]

Allow me to start with two bits of good news:

  1. You have arrived at the 40th edition of the Weekly Head Voices! This blog will soon buy a black leather jacket, start riding around on a motorcycle that is far too big for it and see its therapist concerning its little “Is this all there is?” existential crisis.
  2. Spring has arrived in suburbia! Today was glorious, with zillions of little kids running around outside in the sun, and parents chatting contentedly about the barbecue potential of the coming season. See this camera-phone impression:

Scenes of spring, straight from the hood.

It’s been a really busy week, so let’s get started. In a surprising and innovative move, I’ll be using headings instead of bullets to indicate each new item in this week’s Weekly Head Voices!

Internet Video Conferencing

I had to organize a mini internet-video-conference, i.e. more than two people at different locations chatting with voice and video over internet. Skype you say? No sir, Skype wants more money for this functionality. I’m already paying them for Skype Access and for the odd VOIP call to a PSTN line, but I find this extra surprise inexcusable. Therefore, without any further ado, I bring you this week’s WHV Review:

  • Skype for video conferencing: SUCKS.
  • TokBox for video conferencing: RULES! I was able to set this up in 2 minutes, and it required no software besides flash-enabled browsers at all nodes. All conference participants get a link and can join immediately, without logging in. Unfortunately, TokBox is stopping their service in April, as they’ve changed their business model and are  selling their tech (OpenTok) to OEMs. After April, I will probably look at PalTalk for my free video-conferencing needs.

Powerline networking

Because one of my favourite WAB (Work Avoidance Behaviour) routines is to further optimise my home network (1 cable modem, 3 router / access points, 2 servers, 3 laptops, 1 media centre and 1 networked game console), I bought PowerlineAV adapters to bridge one of the wireless sections (pulling cables between the floors involved is a schlep). Hey, that brings us to this week’s second WHV Review:

  • Powerline / HomePlug powerline network adapters: SUCKS! Read all about it in this detailed blog post on my nerd blog.

Hacking

(NERD ALERT! NERD ALERT! skip this paragraph if you’re not an uber nerd.) I’m old school, so when I say hacking, I mostly mean doing hardcore programming. I fixed a nasty and long-standing bug in the GSVideo video acquisition stack for processing and wrote about in another nerdy blog post, and then I updated my multiple-marker modification to NyARToolkit for processing to support the P3D renderer. Huh?! You should’ve skipped this paragraph!

Fetishes

As is undoubtedly the case with all of you, I possess quite a number of fetishes, two of which I’m going to share with you today. Don’t worry, they’re relatively safe.

I used to be one of those die-hard Norton Commander users in the DOS days. Norton Commander was what is called an Orthodox File Manager, or OFM. My OFM-fetish has been dormant for years, but has come back with a vengeance due to my rather late discovery of Far Manager. What a crazy and wonderful piece of software! (To you Loonix-fetishists: MC doesn’t even come close. Unfortunately, Far is Windows only.) Check out the special effects:

Far Manager version 2. This thing has more hot-keys than you have keys on your keyboard. It can do ANYTHING.

My long-time musical fetish, the brilliant Trent Reznor (Nine Inch Nails ring a bell?) won an Oscar for his work, together with Attacus Ross, on the Social Network soundtrack. By the way, the movie also pleasantly surprised me, and would have done so even without Reznor’s brilliant work.

Conclusion

My brain has served up very little backyard philosophy this week, probably because I’ve been too busy acting like a little code-monkey, so I’ll limit my philosophising to the following:

  1. Thou shalt not link facebook and twitter status updates. These are two different forms of media, and you’re possibly alienating (that’s a big word for “ticking off”) your most loyal followers, i.e. the fantastic people following you on both networks, with duplicate status messages. See it as a challenge to drive each of your social networks in a way which most suits its nature, or see it as double the opportunity to express yourself!
  2. I’ve quoted this once before on this blog, but there are new readers, and it’s good to be reminded every so often: Be kind, for everyone you meet is fighting a hard battle. — Plato.

That’s it for this week kids. Have a beautiful and springy week!
