Nerd-alert: Ubuntu Linux 12.04 on my NVIDIA Optimus Samsung NP300V3A laptop

cpbotha — Wed, 02 May 2012 08:01:14 +0000

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.

Google Drive: Not reliable yet, but potential.

cpbotha — Fri, 27 Apr 2012 20:47:56 +0000

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.

To summarise: Google Drive is Google’s answer to Dropbox (and 50 other inferior syncing services). You install a small app on your Windows or Mac (no Linux yet, although it has been promised), and then it’ll keep a folder of your choosing in sync with Google Drive in the cloud. You can access your files via the website drive.google.com (google docs, but slightly updated), any computer with the Google Drive software, or via the Google Drive mobile apps. You can also share files through authorizing the relevant google accounts, or via URL. Google Drive has a number of built-in viewers, meaning that users will not have to install PowerPoint to view your PowerPoint presentation for example.

Things start to deviate from Dropbox when we look at the storage plans and prices the big G is offering:

You get 5G for free. For a measly $2.49 per month, you get 25G of storage, and 30G of GMail storage as a bonus, and for $5 per month you get 100G! Compare this with the $10 / month Dropbox wants for 50G. This, together with the fact that you could go up to 16 TERABYTES if you would want to, makes you at least think for a bit.

I installed the client on this Windows laptop. For you screenshot-freaks, here’s the context menu for the systray icon:

Google Drive systray context menu.

Note that because I pay a measly $5 / year for 25G of extra GMail space, I’ve been grandfathered into 25G of Google Drive space. Heh, I also only just learnt the term grandfathered. It means I could get this because of my previous price plan that doesn’t exist anymore.

Here’s the preferences dialog, nothing special really, unless you have a screenshot fetish:

Google Drive preferences dialog.

For me also an important functionality: You can easily recover deleted files. If you delete a file on your client computer, it gets synced to the trash folder on the google drive website, from where undeletion is an easy click on the “Recover” button away. Under the File | Manage Revisions you can retrieve file versions up to 30 days ago, or 100 revisions, whichever comes earlier.

Another important difference is that Google Drive, as far as I could find out, does not do something similar to Dropbox’s LAN sync, a pretty cool function that will grab files from the computers on the local LAN if they’re available, instead of from the cloud.

So I set out to do some tests. Before I could really get started, I ran into the first problems. I created a text file in my Google Drive folder with Vim (yes, I use Vim. deal.), as I wanted to test the file revisions. As you know, when Vim saves a file, it first writes to a temporary file, then deletes the original file and finally renames the new file to the original file. This confused Google Drive to no end. For each save, Google Drive created a new file with exactly the same name in the web interface, whilst on the client side, there was only one file.

I then proceeded to delete the text file on the client, leaving me with the following situation, even after Google Drive was done syncing:

Huh?! You call this syncing?

As you can see, on the server is my text file, on the client nothing. I expect of a syncing solution to actually, uhm, synchronise my files. I did notice a sync error message in the systray context menu. After clicking, I got this dialog:

Informative error message. NOT.

Yes, thank you Google Drive, you have an unknown issue. That’s just great.

So, in spite of the really attractive offering, this type of wonkiness (multiple files due to stupid create-new-rename saves, sync errors soon after), even after a few minutes of playing around, does not instil confidence or trust. If there’s one thing a good sync service should do, it’s instil confidence and trust. Dropbox has never failed me, and I’ve thrown some pretty strange things at it. Until Google Drive is able to do the same, I’ll continue coughing up 10 bucks a month for Dropbox.

The rhythm of life

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

Click here to view the embedded video.

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.

Intermezzo – this post’s title was inspired by this Italian masterpiece:

Selling one’s soul to the Virtual

A week ago, I started going through my bookshelf trying to find books that could potentially be given away or sold, freeing up some space for I’m not sure exactly what. Here’s a photo of some of them:

Books traded for space.

Each of these gave me pleasure at some point in my life, taking me on journeys to faraway corners of my imagination. Each of these contributed in some way to the ball of thoughts that is me. Years ago, I would not have considered giving even a single book away. Now I do, because I convince myself that everything is available digitally. I do read on my Kindle, where everything is far more convenient and takes up zero real-world space. I can never lose anything again. If I want anything, I can either find it in my archives or acquire it anew.

Could this line of reasoning, this position, be something that’s really quite insidious? Besides containing information on their pages, the books are tangible and visible reminders of the knowledge that they represent. By getting rid of them, could it be that I’m exchanging parts of my soul for an empty, virtual promise, for oblivion? Maybe the books should remain there, on my bookshelf, as constant physical reminders of the knowledge that they brought me — of all the knowledge that I should continually cultivate and upgrade.

Maybe the time has finally come for the 21st century reboot of Microsoft BOB. :) Then a failed (and the brunt of many jokes) experiment, perhaps now the seeds of a solution to the problem of trading the physical for the virtual. Imagine a private room where you can walk between your virtual bookshelves, a virtual haven to keep your slow, real humanity intact.

Life philosophy that works

Neil deGrasse Tyson is a prominent American astrophysicist and science communicator. Recently he took part in a IAmA session on reddit, where he answered the questions of random reddit users. To the question “What can you tell a young man looking for motivation in life itself?” his answer was the following:

The problem, often not discovered until late in life, is that when you look for things in life like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people in life recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation.

For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You’d be surprised how far that gets you.

This will definitely find its place in the Unified Dogma of Me (UDM). For now, I’m doing my best to fuse it permanently with my atoms.

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 managed to release a stable version of DeVIDE, my Frankenstein-Borg software system for visualization and image processing, only about 2.5 years after the previous stable release. Go get yours fresh from the oven, it’s completely open source!
It seems like yesterday when I got to design and teach the first MedVis Ninja course at the TU Delft. The fourth generation of students have just started with the course (partly the reason for pushing out a new DeVIDE release). The previous generations are kicking ass as we speak, and I’m proud of ‘em all.
I had the privilege of giving another invited talk, in Dutch, at the yearly conference of the Dutch Anatomical Society. In my talk, titled Data Visualization: Driving the human visual system for fun and profit, I introduced data and medical visualization, and then discussed three illustrative examples in more depth: high quality volume rendering (work by Thomas Kroes), diffusion tensor imaging (work by Jorik Blaas) and fMRI connectivity visualization (work by André van Dixhoorn).

That’s it for the status update. The sciencey bits I thought were worth mentioning are:

There’s been some press lately about the letter to the Wall Street Journal, signed by 16 scientists, in which they try to make the case that climate change is really not such an issue. Climate change denialists everywhere rejoiced, I cringed. I really don’t like denialism. Fortunately, it turns out that I’m not the only one, and that there’s a story behind the story: The WSJ editorial board is severely biased against climate science. Another letter, signed by 255 real scientists (all members of the US National Academy of Science), dealing with the realities of climate change, was flat-out rejected by the WSJ. It’s a shame that the first factually dubious letter got so much of the press. Read more about the whole debacle in this Forbes article.
A recent Psychological Science article contains the results of a study on more than 15000 UK inhabitants, as well as on a group in the US, that shows that lower cognitive ability predicts greater prejudice, manifesting in for example right-wing ideologies or homophobia. Ha ha.
In another not-so-surprising turn of events, it turns out that alcohol does indeed make you more creative. FrancoisMalan.com sent me, albeit indirectly, this Consciousness and Cognition article, titled Uncorking the muse: Alcohol intoxication facilitates creative problem solving. Note the creative title, draw your own conclusions about the state of intoxication required for authoring a successful scientific article. Ahem.

Good science should be reproducible. Judging by the blood alcohol content and weight tables on Wikipedia, I should be more creative between 3 and 4 beers, a result I will certainly try to confirm during my next WHV writing session. It is left as an exercise to the reader to calculate my body weight based on this information.

Slow philosophy. [Weekly Head Voices #64]

cpbotha — Sat, 28 Jan 2012 22:23:13 +0000

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.

Oh well.

I did bring you a photo of Disa Uniflora, a special little orchid that likes living close to little waterfalls, for example just like the one that can be found on your hike up Leopard’s Kloof. Look:

Pretty Disa in Leopard's Kloof.

As is usual for sunny vacations during which we transition into a new year, a number of realizations and resolutions slowly bubbled up to the surface from some usually submerged part of my consciousness. I’d like to share some of them with you:

Life goals are bad. Let’s stop doing them. The problem is that humans are awesome at adaptation. Unfortunately this means that two days after having celebrated your latest epic life achievement, you’re bored with it. Some people even get bored with their lives in general, and then buy a leather jacket and a motorbike because they think that that’ll somehow solve the problem, only to get bored with their new image soon after. Fortunately, there is a way to sidestep the problem quite elegantly. Don’t set life goals, but rather set life directions. Instead of defining the point that you want to go towards, define your preferred direction. If you do it right, you’ll pass those points as you go along in any case, except you won’t land in the depressing goal vacuum right after reaching the point that you’ve been moving towards for so long, because you’re motoring along in a direction, and that’s what’s important. To those more mathematically inclined, ignore the life function, rather design its derivatives. This is a practical way of applying the well-known addage that life is about the journey, and not the destination.

Disconnecting is good. I do love the internet. I also think it’s one of the most awesome achievements of the whole of humankind ever, and it really empowers humans everywhere. I’m more or less addicted to being constantly connected, having constant access to the sum total of human knowledge and in principle to a large percentage of my fellow humans. However, there is a fine line between having constant access and being constantly interrupted by too many not necessarily valuable packets of data. We’re very vulnerable to this latter situation, due to our brain chemistry being optimized by all of evolution for novelty, and for foraging, so we keep on clicking on “refresh”, and our ears perk up whenever a phone goes “ping”. However, when not being interrupted, human thought gets the room it needs to grow and deepen, into importance and into impact.

I’ve also been thinking about consumption. I’d like to do much less of that, and when I do, I’d prefer to consume quality. In my thoughts, it was primarily about information, but it applies to many other things. It’s an ongoing process.

I’m adding all of these to my growing list of little life tips. As regular readers of this blog, you know some of these by now: Keep on striving for balance and harmony, focus on the now, create value, study your manual, and, most importantly, drink lots of coffee. One day I’m going to combine them all nicely into the Unified Dogma of Me (UDM) and then I’ll start a sect. Seriously though, it’s quite challenging keeping these and the other ones in the front of my mind all the time. The UDM would definitely help. And I could start a sect.

One more thing before you go: I came across this recent PNAS article via the science pages of my newspaper. William Ratcliff and colleagues at the Michigan State University showed with a terribly simple experiment that single-celled yeast cells can evolve into multi-cellularity quite quickly. Pouring yeast from one test tube into another about 60 times, an action that favours, or selects, yeast cells that clump together, resulted into a multi-celled organism: The clumped together yeast cells started showing internal specialization. Pretty awesome results, especially considering the fact that you could probably reproduce this experiment in your kitchen.

That’s all for this week kids. Have fun evolving!

I recently came across this hauntingly beatiful time-lapse view of Earth made from the ISS (the International Space Station! Yes, we have one!):

Watching this, my nostalgia flared up. You see, I’ve been addicted to science fiction ever since I can remember. It started with Buck Rogers, and the original Star Trek, and only got much worse when I discovered Arthur C. Clarke, Ray Bradbury, Isaac Asimov and Douglas Hill. I find Kubrick’s 2001 and even the sequel movie 2010 beautiful.

For the longest time, I wanted to be an astronaut. I think I still do.

I believe I might have thought that my career plans would be seen as childish when I wrote this short piece for school detailing my life plans when I was 7 or 8 (late eighties, not saying anymore):

My life plans as a 7 or 8 year old. My brother found this somewhere and put it on facebook. I wonder what it would be like to go back in time and explain that concept to myself.

For those of you without the required Afrikaans background, here is a short translation, as true as possible to the original:

When I gow up, I’d like to work with computers, because then I’ll become really smart and I’ll know more about the outdoors and nature. As I grow older, I’ll become a professor, because perhaps I’ll find a cure for leprosy and after that I’m going to study to be a millionaire, because then I’ll go abroad or around the world.

Not a bad plan for a 7 or 8 year old, if you don’t mind me saying so myself. This note has in fact reminded me that there’s still more than enough decisions to be made and work to do, so I’ll have to postpone becoming an astronaut for a little while longer. At least by the end I’m going to end up a rich traveller, which is probably not a bad deal.

In other news this week:

It seems like just the other day that I made my 400th connection on LinkedIn. I’m happy to report that I broke the 500 barrier two weeks ago, and now I have that fancy looking “500+” next to my name. I finetuned my headline to celebrate the occasion, after which I promptly got approached by a head hunter.
Jonathan Dyer is the guru of facial hair. Check out all the beard types and accompanying facial expressions that he has mastered. Yes, that’s a hint of jealousy that you detect in my writing.
More reasons to love the coffee: Giving rats the equivalent of what a human gets after two cups of coffee, the caffeine caused nerve cells in a certain region of the hippocampus to show a significantly bigger burst of activity. These strengthened synapses might have a role in learning and memory. Read this summary on boingboing and the article on Nature Neuroscience.
In an exceptionally disappointing move, South African parliament has passed a new secrecy bill that gives members of government the power to declare information a state secret, thus deterring honest-keeping journalists and other whistle-blowers with a 25 year jail sentence. Desmond Tutu sums it up nicely when he says that this makes the State answerable only to the State.

If this new bill manages to make it through the constitutional court as well, the country is going to take a giant step backwards. At least we’ll have facedrink to cheer us up again!

I completely lack the genes that usually cause human males to have a thing for cars, but I do love Top Gear. This trailer for a fictional 60s detective show, made by Jeremy Clarkson, James May and Richard Hammond, encapsulates many of the reasons why:

Moustaches, guns, girls, cars and Hammond karate-chopping the porter at Playboy Club London for absolutely no reason whatsoever at 41 seconds can be nothing but 100% pure AWESOME.

It’s crazily busy at the moment, for a large part due to the extra load of having to teach and revamp, AT THE SAME TIME, the TU Delft’s postgraduate Data Visualization course. I’ve chucked out the written exam and the structured lab work, and exchanged it for paper reading, class discussion and four independent projects, inspired by positive experience with my Medical Visualization Ninja Training Course (third year in the running, Ninjas all over the place!), the postgraduate InfoVis course I gave at Stellenbosch and of course the teaching materials of esteemed colleagues at UBC, Harvard, Berkeley and Stanford. With a bit of luck, we will soon deliver a whole class of new-style DataVis Ninjas.

At a recent conference, I ran into an erudite half-British colleague from the far North, who in a few minutes almost managed to turn my world into rubble. You see, I’ve always proudly promoted the use of the -ise forms of certain words, such as visualise, realise, colonise and so forth, these being examples of British English. (Obviously, I adapt when American English is required.)

It turns out that, as is the case with life in general, it’s unfortunately not as simple as that.

It turns out that many of the -ise words are originally from the Greek or the Latin with “-ize” endings, and therefore the Oxford spelling prefers their use, although it accepts the “-ise” forms as well. On the other hand, the Cambridge University Press, as well as the mainstream media and most of the public in Britain and the former colonies, has a strong preference for the “-ise” forms. Certain other words like for example advertise, advise and surprise always take the “-ise” form in British English.

So now I’m faced with this conundrum. It would otherwise not have been such an issue, but the words “visualise” and “visualisation” come up quite often during my work day. Sticking to “-ise” is easier and still correct when in British English mode, but “-ize” for those few words of Greek and Latin origin could perhaps be considered more correct, and has the great advantage of allowing me to standardise on “visualize” as the canonical form of that important term. However, then I would run the risk of confusing the “-ize” and the true “-ise” words in Oxford English, potentially leading to painful embarrassment at the many cocktail parties that I frequent.

So you see, the Universe is just full of mysteries. Another mystery that has plagued humankind for decades, is what would happen if Stephen Hawking and Albert Einstein got involved in a rap battle. Well humankind, wonder no more:

Ok kids, thank you for tuning in again. Have a great week, I hope to see you again soon!

Happiness slingshot. [Weekly Head Voices #61]

Make sure you won’t be disturbed for the next 2 minutes and 57 seconds, and then focus your full attention on this marvelous YouTube clip:

Yes people, there are apparently some brilliant human beings, the pinnacle of our society you might say, who took the time to construct a giant slingshot with which they then proceeded to shoot each other through the blue summer sky. This is the sign that we, the human race, must be doing something right.

Because I need all the time that I can get to play may part in being a good human, I will now switch to Bullet Time(tm):

IEEE VisWeek 2011, Mind-Blowingly Awesome Visualization Conference, took place in week 43. For the first time in years, I was NOT there. The TNR went and came back inspired. My fearless and revered ex-leader Frits Post received the IEEE VGTC Visualization Career Award, which is yet another official recognition of his awesomeness. I hope he still has some space on the mantelpiece next to the Eurographics Honorary Fellow award.
Through the #visweek conference twitter stream and some of the blogging that was going on, I was able to follow the conference at a distance. There was a Blogging about Visualization BoF (birds of a feather, a kind of informal meeting to discuss some topic of interest; also read Dominikus Baur’s blog report), which motivated me to revive the MedVis.org webblog! We even have a twitter account now. If you have even a mild interest in medical visualisation or imaging, please subscribe via email, your RSS reader or the twitter account.
This blog won one of Joe’s official SA Blog Awards! Buy me a beer when you see me.
A real Italian explained to me that putting sugar in your espresso is entirely acceptable and even desirable. Herewith I’m going to stop feeling ashamed about my sugar-in-espresso habit. I’m not sure what I was thinking that combining two of the best substances known to humans was a sin.
After spending some serious quality time with The Email Game, I wrestled both of my overgrown inboxes to the ground. Lessons learnt: 1) Even the thin layer of gamification offered by The Email Game was sufficient to motivate me to start and finish a task I’ve been dreading for weeks. 2) Inbox Zero actually is more important than I’ve recently come to think. The trick is deciding when exactly you’re going to empty it.
Here’s a picture of a hedgehog after a bath:

It's a hedgehog. After a bath!

So recently I was having a conversation with someone in a bar. Soon the question came up: What are you striving for in your work?

Imagine my surprise when I didn’t have an answer ready. I was surprised, because I usually spend a significant amount of time on introspection, pondering the usual questions:

What makes me happy?
Why are we here?
What should I strive for?

I mostly have answers to all of these and more, often involving coffee drinking in some form, along with a healthy dose of perspective, and harmony. However, due to general work-related business the past few months, my moments of introspection have been few and far between. As is the case with these types of philosophical guidelines, one does need to spend time regularly pondering them, else they sink quickly deeper below the surface of everyday life.

So I spent some time trying to remember what it was that I was striving for in work. Fortunately, not that far below the surface, I found it again:

Create value.

That’s really all there is, but it works for me.

Ladies and gentlemen, welcome to this, the sixtieth edition of the Weekly Head Voices!

I know that I’m terribly late, so I imagine that you’ve probably missed my incoherent babbling. To try to make up for this, allow me to present you with this YouTube clip of me babbling almost coherently for 20 minutes! In week 41 I had the privilege of giving an invited talk to an audience of 100+ medical imaging geniuses at the yearly symposium of the Netherlands Forum for Biomedical Imaging in Leiden, and the whole thing was recorded by the artist formerly known as fpixel:

If you’re not into academic talks, I suggest the following YouTube clips as alternative entertainment: First, the new Avengers trailer resulted in the accute arrest of my teenage comic book fanboy heart. Besides all the superheroes (SUPERHEROES!) some Next Level Human Being (NLHB) opted for Nine Inch Nails as soundtrack! The previous time I gushed this much about a trailer, was with Iron Man 1 and their choice of Black Sabbath, and you of course remember how that turned out.

Second, do you remember that dude in the really terrible Police Academy movies who could make like a million sound effects WITH ONLY HIS MOUTH? His name is Michael Winslow, and with the following clip he has completely redeemed himself:

So now let’s get back to talking about me.

I grew up eating science fiction books for breakfast, lunch and dinner and dessert. I was one of those strange kids who used to read secretly under the covers (with the backlight I ripped off my microscope of course. yes, I owned a microscope you jock.) whilst I was supposed to sleep. Please try to imagine what it was like when I read last week that Virgin Galactic has just finished building Earth’s first commercial spaceport. People, we have our first frikking spaceport, you know, where spaceships take off and come to land!

We’re living in a science fiction novel.

We kick off this week’s edition of the WHV with Ben Goldacre giving his TED talk on “Battling bad science” at 180 km/h:

He’s fabulous, isn’t he? If you haven’t done so already, you should really read his book “Bad Science” too, and don’t forget to hand a copy to anyone in your neighbourhood that might be confused about homeopathy, accupuncture, any other forms of alternative medicine, or anything by Patrick Holford, vitamin-peddler of note.

On a completely different note, I’ve fallen in love with a piece of software again. This time it’s Zotero, open source reference manager. For those of you not into writing (scientific) articles, a reference manager is an indispensable tool that keeps track of all the other articles that you’ve studied and helps you to cite them correctly whilst writing your latest attempt. I tried Zotero in 2009 but wasn’t that impressed. It seems that much has happened since, as I’ve been completely blown away this time. Killer feature #1 is the extreme ease with which I can import new references, by clicking on the little icon in my Firefox 7.0 url bar (Zotero 2.1 is a Firefox plugin). If the PDF is available, it’ll add that as well. I can also just drop a PDF directly in there and tell it to extract metadata to make a bibliographic entry. It does this surprisingly well. Killer feature #2 is the explicit support for storing one’s reference database anywhere else, for example in one’s Dropbox, another piece of software with which I have a long-term romantic involvement and which in this case ensures that I have transparent access to my whole reference database, via Zotero, from any computer I care to use.

(NB: If you’re going to do this, make sure you don’t run Zotero concurrently on multiple machines. A better solution, which I’m now using, is to have only the zotero “storage” folder in your dropbox, and then symlink that into the default zotero firefox profile directory. Please let me know in the comments if you need more detail on this.)

Just in time for our regular coffee-themed blog post interlude, there’s been yet another study on coffee-related health benefits, and now it looks like coffee drinking may also protect against depression in women. As you will recall, I recently blogged about the coffee-related prostate-cancer protection. Seems coffee is perfect in one more regard: It’s an equal opportunity health benefit!

For my birthday, TNR bought me Anything You Want by Derek Sivers, and beamed it directly to my Kindle (go 21st century!). Derek Sivers is the guy who started CD Baby almost by accident, a company that became the largest seller of independent music on the interwebs. I say by accident, because his goal in the beginning was purely to sell his own CDs online (which was quite a feat in 1997, as there was no PayPal and not that much WWW yet), and then friends asked if he could sell their CDs too, and before he knew it, he had 85 employees, 150000 musicians and 100 million dollars in revenue. It’s a fabulous story, all the more because he really just wanted to keep his company as small as possible and do what he loved.

The book is chock-full of philosophical nuggets, for example the one that inspired the title of this blog. Sivers explains that when you have to decide whether to commit to a new project or not, there are only two choices: It’s either HELL YEAH! or NO. Your time is too limited to take on just yes or even maybe. Makes sense, no?

What really resonated with me however, was the following thought on how people grade themselves:

For me, it’s how many useful things I create, whether songs, companies, articles, websites or anything else. If I create something that’s not useful to others, it doesn’t count. But I’m also not interested in doing something useful unless it needs my creative input.

I think that I’ll leave it at that. Now go have an epic week kids!
