New Samsung NP300V3A laptop is welcomed into the family!

It’s traditional around these parts that I write a post whenever I get to welcome a new computer into the family. In July of 2002 it was Dr. Evil, more a brick than a laptop, in May of 2004 it was my beloved 14″ HP NC6000 laptop, in July of 2006 I met my 15.4″ HP NC8430 (employer-supplied, thank you employer!), which in turn led to this Ubuntu-critical blog post of mine that attracted 50000 (yes, fifty thousand) readers over 2 days, in July of 2008 I splurged on a lovely quad core desktop machine, in September of 2009 I acquired an Asus 1005HA-H netbook, and in November of 2010 my employer got me a super-strong Dell Latitude E6410 laptop.

Today I welcomed the latest and probably prettiest laptop so far into the family:

Pretty Samsung NP300V3A-S01NL laptop!

Behold the Samsung NP300V3A-S01NL (Series 3). It has an absolutely gorgeous-to-type-on chiclet keyboard, a 13.3″ matte (!) display, NVIDIA GT520m graphics with Optimus, second-gen Core i5 2410m, 4G RAM and 500G disc, all for a terribly reasonable price, which is important, as this one is not employer-bought. A man needs a laptop like this for his top-secret personal biznizz, yes?

It’s running Windows Home Premium, so I have to use Truecrypt instead of EFS for encrypting my biznizz, which is stored mostly in my Dropbox pro account. The battery life is quite impressive probably due in part to Optimus switching. The drawback of this is that I probably won’t be putting Linux on here anytime soon. These days you can use both the graphics adapters in Linux, but both of them stay active all the time, so it kills the battery really quickly.

We learn at least two more things from this post:

  1. I do seem to exhibit a certain obsessive compulsive behaviour when it comes to keeping track of the arrival dates of the various computers in my life.
  2. When spring comes around, hide my credit card.

Update on May 2, 2012: I have just eaten my hat. Ubuntu Linux 12.04 with Bumblebee runs just wonderfully on this laptop. Read all about it in my VXLabs blog post.

Microscopic Orchestra [Weekly Head Voices #53]

Dear friends, I was planning to write a nicely focused post, but it’s definitely not going to be this one. There’s just too much we need to talk about, and by “we need to talk” I of course mean that “I need to do my monologue”. Do strap yourselves in, as this edition of the WHV has tea, peanuts, chocolate milk, general nerdery, some ground-breaking science and even some thought-provoking art.

Nutrition

Will the real Rooibos please stand up?

Rooibos is a brilliant herbal tea from the Western Cape province (the same one that spawned me) of South Africa. It is both tasty and super healthy. As I was shopping for my stash in the local Albert Heijn (huge grocery chain here in Dutchieland), I found all kinds of Rooibos blends, for example with honey or even with orange. Now while I appreciate the fact that you can even find Rooibos in any old store over here, the only good Rooibos is of course PURE Rooibos, so I was quite happy to find the most non-descript Albert Heijn box stating just “Rooibos” (not an orange or honeypot in sight), and also the Pickwick box proudly proclaiming “Pickwick Rooibos Original”. I was considerably less happy when I noticed in the list of ingredients (list? it’s supposed to be just tea!) that the addition of cardamom, cinnamon and ginger (!!!) to these supposedly original specimens was apparently acceptable. In the words of an entrepreneurial friend of mine: MUPPETS. Fortunately, the boys and girls at Zonnatura do get it, and have the right stuff on the shelves, pure and uncut. As if fate needed to equalise this advantage however, their website is pure and absolute Flash suckage. Go figure.

On the topic of healthy nutrition, there are two more tidbits I’d like to mention:

  • Peanuts are of course not nuts, they’re officially beans, or legumes. When further perusing the wikipedia page on peanuts, one is most pleasantly surprised to find that this delectable snack is in fact also super food! Allegedly the favoured core nutrition during (Ant)Arctic expeditions, peanuts contain more protein than any true nut, oodles of carbohydrates (570 kcal per 100g) and also 30 other hardcore nutrients and vitamins. No Vitamin C though, so the perfect diet would unfortunately still require more than just peanuts and beer.
  • This one surprised me more: In a number of studies, for example this one from 2006 and this very recent one from the University of Texas, it was found that (low-fat) chocolate milk works really well as a recovery drink after strenuous exercise, better than those really expensive sports drinks you always see real athletes prancing uselessly around with. CHOCOLATE MILK people!

Nerdery

  • HTC’s Android phones run Sense, a graphical user interface layer over mostly Google’s smartphone operating system. Sense is really quite cool, except for the fact that it’s too easy accidentally answering or declining calls when fishing the phone from your pocket, as HTC has mapped these actions to vertical swiping instead of horizontal swiping. On my nerd blog, I’ve written a short post on how to work around this problem.
  • I’ve recently installed the Rapportive plugin for GMail. Whenever I view or compose a mail, Rapportive shows incredibly detailed information on the recipients or senders in the right sidebar, detail that it grabs from services such as facebook, LinkedIn, twitter and so forth. Obviously you also get to see recent emails between you and said senders or recipients. This context information makes a huge positive difference in the mails that you are able to craft.

Science

I had the privilege of accompanying Genetic Offspring Unit #1 to Naturalis, National Museum of Natural History, in Leiden. On the ground floor, they have a reproduction of the Miller and Urey experiment published in ’53. This was a landmark experiment during which Miller and Urey tried to show that under the conditions on primitive Earth, organic compounds, such as amino-acids, would be synthesised from inorganic precursors. They built a relatively simple closed setup containing only water, methane, ammonia and hydrogen, added water evaporation and an electrical spark (simulating lightning) to the mix, and voila: amino acids, the building blocks of proteins in living cells!

Although more recent evidence suggests that the general atmospheric mix was probably not exactly like in the Miller-Urey experiment, their work did pioneer the study of the origin of life on earth. Current scientific opinion varies from organic compounds arriving here by meteorites, or that organic molecules may have indeed been synthesised in localised reducing environments such as those proposed by Miller, for example near to volcanic plumes!

Now that’s just hardcore.

Art (and a dash of backyard philosophy)

On the top floor of Naturalis, I arrived at what was to be my absolute highlight of the visit: An art installation by Matthijs Munnik called “Microscopic Opera”.

There are better photos of this installation online, but this one is mine.

The installation consists of 5 petri dishes filled with mutated C. Elegans worms, each moving differently due to their mutations. Above each petri dish is a microscope-camera feeding the video to an analysis algorithm that turns each worm’s motion into a different choir voice. The total effect is altogether eerie and quite mesmerising. The artist intriguingly writes:

… I’m also fascinated by the worms, who have no idea of the world above them. We are like gods to these little lab worms, following them from their first cell division to their death, manipulating their bodies and mutating their DNA. Are we really like gods, or are we like the worms, unaware of the things above us in a different dimension, the biggest thing becoming the tiniest.

I think I’m going to leave you with that. Have a beautiful week, worms!

Opportunity Cost [Weekly Head Voices #52]

On Thursday July 14, 2011, it rained for 20.5 hours straight, and it did so from all directions at the same time (yes, apparently also in the upwards direction as my wet socks will attest). The last time it rained this much on one day, was on July 17, 1954, as confirmed by the paper this weekend. I believe I might also have broken several swearing records (in terms of duration, variation, originality and vehemence) whilst struggling through the water on my bicycle, on my way to my work.

I think the Dutch climate is just trying to remind us that it’s just really not nice, and that this “summer” that others speak of is merely a figment of their imagination. Probably for the purpose of wound-focused salt-rubbing, the weather every so often does have its moments, like this morning in my garden when I managed to photograph some bees doing their thing in the few minutes that the sun timidly managed to appear before being assertively occluded by infinitely high stacks of angry-looking clouds:

Besides complaining about the weather, I did want to discuss briefly with you an interesting economic concept, a concept that I’ve decreed will henceforth go through life as a  backyard philosophical idea. The idea that I’m on about is called opportunity cost, and refers to the cost that one incurs engaging in an activity, measured in terms of the best alternative that one could have engaged in otherwise. For example, if you’re sitting around refreshing your Twitter / Google+ / Facebook  instead of implementing a new and improved type of internet-connected sliced bread, potentially worth ONE BILLION DOLLARS, the opportunity cost of your social networking addiction at that point is, you guessed it, ONE BILLION DOLLARS. I really like the idea that Friedrich von Wieser named this phenomenon (that I have previously unknowingly touched upon) and will henceforth apply it liberally. So if I walk away from a conversation, mumbling something along the lines of ONE BILLION DOLLARS, you know why. Seriously though, it is good to keep this idea in mind in everything that you do, especially since cost can be measured in ways other than hard currency.

… and now for something completely different:

I have recently received the joyous news that a certain musical genius and his mind-blowing audio-visual spectacle are planning to be present at a certain festival that is soon to take place:

Just sayin’.

Barbarossa Town [Weekly Head Voices #51]

Here’s a photo:

Some train at the Rotterdam Station. I spent lots of time in these the past week.

… and here are four things, most of which happened last week:

  • I was honoured to be invited by the International Research Training Group (IRTG) of the University of Kaiserslautern to visit their institute and give a presentation on medical visualisation (my field of research, for those of you joining very late). Unfortunately, I was only able to stay an evening and a morning, flanked by two 7 hour train rides. In spite of my short stay, the exceptionally friendly Kaiserslautern peeps managed to put together an enjoyable and especially very efficient program with dinner, a morning of research discussion  and of course my talk, which was only 45 minutes over time, and a delectable lunch outside. It was interspersed with questions and discussions, which I do like, and most of the audience managed to stay awake (!), but I still do have to take a more serious look into accurately timing interactive talks like this. Thank you very much IRTG, it was a perfect visit!
  • The Delft – Kaiserslautern trip is just so that taking the train seems to make more sense than flying. The total trip time is greater, but the difference is small enough to be justified by the great deal of work one can do on these long train rides.
  • I tried out T-Mobile’s new pre-paid Internet “abroad” option, called Travel & Surf. One pays EUR 4.95 for 50 MB over 24 hours, or EUR 14.95 for 100 MB (which they call “unlimited”, HAHA) over 7 days. Without this active, my mobile internet works abroad, but in the zone 1 countries (Germany, Norway, etc.) costs me EUR 2 / MB up to a maximum of EUR 60 per month, so it’s definitely nice being able to pre-pay and control the possibly nasty surprises. However, an Android telephone sucks down 50 MB of data without even thinking, unless you remember to deactivate syncing and background data, which does help to quite an extent. This is certainly a good development, but T-Mobile and all other mobile providers are probably still making an absolute killing by acting like it’s really complicated providing internet just over the Dutch border.
  • On the really good news front, Francois Malan’s paper on measuring femoral lesions despite CT metal artifacts has been accepted for publication in Skeletal Radiology! The full citation (so far, it’s online first) is:  Malan DF, Botha CP, Kraaij G, Joemai RM, van der Heide HJ, Nelissen RG, Valstar ER., Measuring femoral lesions despite CT metal artefacts: a cadaveric study, Skeletal Radiology, 2011. Cite it sesame!

Here’s my final thing, a youtube clip that, to my surprise, I don’t think I’ve shown on this blog before. Pay attention, it’s full of braai-related culture and wisdom:

May your week be full of awesome!

The Monthly [Weekly Head Voices #50]

HEY!

I’m still here, and it seems I really have to catch up on my backlog of WHVs, all the more as I was starting to notice the beginnings of BPP (Backlogged Posting Paralysis, of course). So I’ve spent a few minutes gathering a selection of life snippets of the past six weeks (week 21 through week 26) and will now proceed blasting them out this old Web 1.0 exhaust. I wasn’t completely idle blog-wise, however. I did write a post about my EuroVis 2011 and my Schloss Dagstuhl SciVis seminar adventures.

Before the blasting commences, I would like to present some relaxing visual input brought to you via my cell phone camera, which at the time of capturing found itself in my hand, itself being inside the chapel in Herberg op Hodenpijl, a short westward cycle from my house:

Herberg op Hodenpijl chapel roof detail.

The picturesque surroundings are home to the chapel, which hosted an art exhibition at that point, and an organic restaurant and grocer. Most (all?) of the produce comes from a small farm across the road that you can also visit. The goats are really friendly. You could do worse than popping by on a sunny day.

The rest of this post has been categorised, with nice headings, so that you can skim through it even faster.

Health and well-being

  • In a recent cooking insert on the television, two chefs prepared Loup farci en croûte, or sea bass filled with julienne vegetables in a pastry of a thousand layers. Take a look at the video clip: The chefs put an amazing amount of effort into preparing this visually beautiful and apparently delectable dish.
  • My TNR and since recently also business partner, who can often be found hurtling down mountains on various and high-speed forms of personal transportation, and when he’s not is involved in a number of other extreme sports activities, managed to break two fingers on his right hand cycling over the flat and otherwise uneventful piece of earth between the computer science and physics buildings on our campus. Go figure.
  • In a recent study with 48000 (yes, that’s fourty eight thousand) men followed over a period of 22 years, a strong correlation was found between drinking six cups of coffee per day and a lowered risk of prostate cancer. Also men (but can you still call them men?) drinking fewer than 6 cups of coffee per day had a lower risk. The study did correct for other lifestyle factors. The linked summary also mentions other studies in which coffee drinking has been associated with lower risk of Parkinson disease, type 2 diabetes and liver cancer. I guess I can worry less about this addiction than, euhm, the other ones.

Nerd News

  • Dropbox has recently activated functionality they call shareable links, meaning that you can request a unique http://db.tt/some_code link for any file or directory anywhere in your dropbox and share it with anyone else (also non-dropbox users), who is then able to download said file or directory given the link. There’s a page on the website where you can manage all of your shared links, for example deactivating ones you don’t want people to access anymore. Read the help on shareable links for more information.
  • As you might know, I keep a lab journal documenting in some detail my daily work activities. I also maintain a personal journal, mostly for dumping stuff that might be interesting for this blog. I used to do all of this in Google Docs, but for the past few weeks I’ve experimenting using TiddlyWiki (this is a single file JavaScript-heavy wiki implementation) on my Dropbox for all my journaling and personal knowledge base needs. It’s been going swimmingly for at least two reasons: 1) It’s available also when I’m offline. 2) The idea of being able to break out into a new wiki page (called a tiddler) at the drop of a hat takes some getting used to, but fits the non-linear nature of my journal and personal knowledge base entries much better than the mostly linear google docs.
  • I’ve settled on using the free tonido personal cloud software to make all the files on my home server available via the internets. This means I can get to all of my music, photos are whatever no matter where I am. Pretty neat! (I have too much to fit on my 50G dropbox account. There’s also the PogoPlug software, but the free version has its limitations.)
  • Just a few days before Google+ (Google’s new social networking religion, in case you’ve been sleeping for the past week) hit the internets, I installed the Google +1 button on this blog, see right at the bottom of every post. So now you know what to do with every post: Click my +1 button, then click my facebook like button, then leave me some snarky comment right here. Easy as 123, and I’m a happy camper.

Comedy

Whilst flipping through channels one Saturday night,  I flipped right into the stand-up comedian Demetri Martin. I made a note of it in my journal, and now here we are. Watch him present his research findings on his large pad, with his pointer:

That’s it for now dear readers. I really do hope to be back soon, and I hope to do so with a slightly more focused contribution. See you on Google+!

UPDATE 2011-07-23 note-taking strategy

To you I might appear fickle, but I guarantee that it’s just hyperactivity. I’ve since adjusted my note-taking strategy again. As you will have seen in the comments, Pieter Kitslaar subtly influenced me to go searching for a note-taking solution that syncs between phone and everywhere else. Fortunately, I ran into the SimpleNote universe and I’m now officially in note-taking heaven. I have Flick Note on my Android, the SyncPad extension on Chrome (for sometimes) and ResophNotes on Windows and on Linux with Wine. All apps work exactly as I would expect a super-fast and efficient note-taking app to work, with real-time incremental searching, hotkeys everywhere, and best of all, offline use and transparent syncing. ResophNotes is especially cool, definitely give it a shot.

So I’m using this SimpleNote setup for all my personal knowledge base and general note-taking needs. For detailed work and lab journaling, I’m now using linear OpenDocument files on my Dropbox, which solves the offline problem I had with Google Docs, which I do still adore for collaborative work.

Lemme know in the comments what you think!
