e-Books: Online Courses By MIT, Yale, …

February 25th, 2010

I’m a fan of free education. I’m even more of a fan, of education that you choose out of interest, not because it just so happens to be part of a “bigger program” (such as general high school, college, …). Choosing your own courses shows genuine interest, and will lead to better results.

A while back, I wrote about Academic Earth as a free resource for a lot of advanced courses.

Today, I got another similar e-mail. While this usually just gets discarded as spam, this one was actually interesting.

[snip] … to let you know that Guide To Online Schools recently published a comprehensive collection of Free Online Courses and we included a section for Computer Science found here: Computer Science. It includes thousands of links to courses in subjects ranging from architecture to chemistry to women’s studies and these courses are prepared by top institutions such as MIT, Yale University and University of California.

I quickly browsed around, and found several very interesting topics worth reading. There are some 404-pages in that collection, but those that work are sure worth your time. Check it out; Computer Science Courses (eBooks).

I’ll Become A Millionaire: My WIN-WIN Plan!

November 25th, 2009

Here’s what I’m planning to do, in my run for world domination and incredible wealth (this plan aims mostly for the latter part).

  1. I will start a new business.
  2. This business will act without approval of my clients
  3. I will charge them a random amount of money for services that were not requested in the first place
  4. The entire world will thank me for “making the world a better place”
  5. I will retire to a loft somewhere in Hawaii

Does the above sound familiar to anyone? Seriously, no?

It’s what our customs services is doing, right now. I’ve ordered two online products recently, and was happy they arrived within the week (go ThinkGeek.com!). It wasn’t cheap, as I had to pay some pretty fancy shipping costs too. It  got even more expensive, as I later received two seperate bills to pay additional fees (point #3) because customs decided they should check my packages and re-charge them, without my consent (point #2).

With a business plan like that, I’d have retired a long time ago.
Screw you customs, screw you.

TEDx Brussels: My Box Is On Fire

November 23rd, 2009

Today, I was lucky enough to be able to experience a TEDx Brussels conference, a local (independant) spinoff of the popular TED. In case you’re unfamiliar with the concept of “TED”, here’s a brief description.

TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds:  Technology, Entertainment, Design. Since then its scope has become ever broader.

In short: it’s a conference about innovative people, talking passionately about their idea. This years slogan was “Burn The Box“, instead of just thinking outside of it.

Since I unfortunately arrived 45 minutes late (that’s a definate shame on me scenario) due to horribly traffic in Brussels and a chronic lack of parking space, I missed the first talk – and arrived only just as Nicholas Negroponte was descripting the OLPC program.

Nicholas Negroponte: One Laptop Per Child

olpc_nicholas_negroponteI was excided to hear his talk (and glad I ventured a 500m spring in order to get there in a reasonable timespan), because of the effort and publicity that has gone in the One Laptop Per Child (OLPC) project. Nicholas Negroponte explained not only the concept, but since the launch of the project nearly 1.2 million XO laptops have already been distributed to third world countries, allowing for a great “show and tell” – living proof the project works. With it, truancy has dropped from staggering 50% to nearly 0%. Children are motivated to go to school, and learn more. Every XO laptop also has access to 1.6 million E-books, right off the shelf. It’s an amazing tool for education, that has already shown great improvement in the way children today can learn.

The motivation Nicholas has shown during the presentation, and the amount of energy he can poor into the project, really is mind-boggling.

David McCandless: Information Is Beautiful

david_mccandless_information_beautifulOur current situation (newspapers, internet, radio, television) give us a largescale information overflow. It’s up to us to manage that information, and if it were up to David McCandless, we’d use our ability to visualize data to help us with that. A very interesting and practical view of the visualization of abstract data, in order to detect trends, and make the data more readily available to anyone.

The notion of “perception” or “awareness” is based by some key factors: our vision, our taste, our sight, … The combination allows our mind to combine those senses into something we are “aware of“. Something that can have meaning to us. By using new methods of displaying data, beyond the classic Pie Chart/Bar Charts/…, we can more easily identify problem areas, place ideas into context, draw comparisons, explore timelines, … Some interesting examples from him are The Billion Dollar Gram, Left vs Right and Mountains Out of Molehills. Each gives unique insight into topics that would otherwise just be a collection of boring data. It gives meaning to otherwise meaningless data.

Conrad Wolfram: I Calculate, Therefore I Am

wolfram_alphaAnother person of great interest, mathematician Conrad Wolfram, who is largely responsible for the highly innovative search engine Wolfram Alpha, as well as the computational software program Mathematica. The presentation talked about the mystery revolving the following question: “Is it cheating if I use Wolfram Alpha for my homework?“. While it does seem like a fairly simply question, the implications are profound. He makes the claim that our current education of math is fundamentally wrong by teaching us only the methods to calculate, and not the tools to do so. While there’s a general basic knowledge of math we should all possess, we can make much greater progress if can we learn to use the computational tools available. Our current education fails in the sense that we cannot put math into context, where the practical use of math to most is not immediately relevant.

Noam Perski: Carbon Neutral Clouds

cloud_computingWhile you’d expect a mostly environmental talk, his presentation was largely about the concept and advantages of Cloud Computing. Since TED is classically a technically skilled audience, the concept could be explained exactly as it is – without having to place everything into a metaphore (which is something that’s caused a lot of confusion about the ability of cloud computing nowadays). The obvious advantages were discussed (consolidation, power saving, optimization, pricing, …), as well as the evolution towards cloud computing and Amazons EC2 product. Since I’m very familiar with Cloud Computing (both due to work, and personal interest), I could greatly sympathize the subject.

Djamel Laroussi: Three Marabouts

djamel_laroussiThe musical intermezzo was provided by Djamel Laroussi, a leftie guitarist. An amazing display of improvisation on stage, as well as a general musical experience. He though himself how to play the guitar, but bought himself a right-handed guitar and played it left-handed – without switching the strings (which means he new plays the guitar “upside down”). A wonderful show!

Here are some movies that might inspire you:

A break from the classic 2/4 rhythm, and an entry into the 3/6 african rhythm music.

For The Talks I’ve Missed

Above are just a few of the innovative talks I experienced. There were great others given by

  • Dambisa Moyo (about the government aid we’re sending to Africa hurting progress more than it’s helping – more info)
  • Marc Van Montagu (about bio-enhancing seeds to grow in Africa – more info)
  • Michael Bauwens
  • Pedro Brugada
  • Clayton Schaeffer (about land/property ownership rights in third world countries and government influention)
  • Serguei Krasnikov (on the subject of Time Travel, and how we can most probably only find a time machine, and never build one – more info)
  • Marc Millis (the discussion of traveling to distant stars and planets several lightyears away – more info)
  • Catherine Verfaillie (stamcell research and the future of regrowing organs from own cells – more info)
  • R. U. Sirius (pronounce this one! – more info).

While I’ve left out quite a few as a detailed description, it’s worth noting that every talk was impressive and kept us hanging on every word mentioned. Since I’m more biased towards tech-savvy subjects, I’ll be mostly sticking to those.

So?

TED stands for interesting presentations, given by passionate people. It’s about reaching out, and meeting new people – networking. It’s an inspiring event, that I feel can be summed up in the following quick comparison:

  • Parking fines I got in Brussels: 30€
  • Ticket to TEDx: 50€
  • Experiencing a TED: priceless

I’ll be there for next event, where the slogan is “Great Balls Of Fire” as inspired by Jerry Lee Lewis.

Chrome OS: Nice, But Don’t Get Carried Away

November 21st, 2009

Like some million others out there, I watched the Chrome OS Open Source presentation on several of youtube’s movies, and have mixed feelings about its use in todays world. For reference, here are some interesting videos you might want to look into.

There’s a wide variety of design documentation out in the open for you to look into, as well as the source code itself, for you to evaluate. There’s also a developer build Virtual Machine for VMware’s Player, that you can download and boot up – to get the look ‘n feel right. If you want to run it in VMware’s Server, you’ll need to convert the machine first.

Chrome OS is counting on the following events to further expand:

  • More Netbooks are being sold and used, every day
  • More users are migrating to “the cloud“, using webapplications that store all your data on outside servers (facebook, youtube, flickr, …)
  • Phones gaining computer capabilities, and laptops migrating more to phones
Trends in the industry leading to the Chrome OS

Trends in the industry leading to the Chrome OS

In Chrome OS: every application is a web application. That’s the power, and the weakness of Chrome OS. While there’s a trend of moving all applications towards the web, and I’m no big fan of it. There are the obvious advantages (easier administration, one place for storage, backups …), and the obvious disadvantages (security, lack of ownership, lack of browser capabilities, …). You’ll have your standpoint on this, I’m sure – this is just how I feel.

When is Google OS useful to you? When you donate all your privacy concerns to Google, and “migrate” to “the cloud” – using all Google Applications that run in your webbrowser. GMail, Google Docs, Wave, … are all webapplications that run great in a  browser, and it’s a focus of Google – but it’s not a focus of 95% of all the other software being developed. You’re limited with Chrome OS in ways you’ll only realize as soon as you use it. And then you’ll switch back.

Define Happyness: The Act Of Making Someone Else Happy

August 28th, 2009

I don’t often write something personal (and before you remove this site from your RSS reader, I won’t be doing that too often), and usually keep things tech-savvy, but this I felt I had to share. It’s about happyness, romanians, body language and charisma.

Say what?!

Let’s start at the beginning. I work at a Belgian hosting provider, which is located in the Port of Antwerp, one of the biggest in Belgium. Working late one friday evening, I decided to grab a bite at around 21:00h. Night had fallen, the sky was totally black. I walk outside our office building, and find a man walking around aimlessly, holding his (fairly bald) head together with his two arms. He’s obviously in distress.

He slowly walks to me, and starts talking rapidly in a foreign (at this point, undefined) language. I couldn’t understand a word he was saying, but saw him pointing at a piece of paper with an address on it. The Sherlock Holmes in me deducted he probably had to be at that address, instead of this abandoned office building late at night. The big yellow truck behind him probably gave away that clue, too. I read the address, but had no clue where it was.

At this point, I normally would’ve gotten in my car with built-in GPS, and just drove home. Screw him. Would that make me a prick? Would you trust a trucker late at night, when you’re all alone?

Having rememberd the movie Yes Man, I felt like saying “yes” for a change. Let’s do a good deed, and help this lad out. Using body language that would’ve impressed quite an audience, I guided him to my car (and I think at this point he was probably thinking “should I trust this IT guy late at night, when I’m all alone?“), forcefully removed the paper with the address from his hands, and entered it into my GPS. He saw the route he had to take, but somehow couldn’t orient himself to get there, despite my best efforts at Dutch, French, German, English and Sign Language. Probably because I was confusing all 5 of those amongst eachother, making it complete gibberish.

In between this hectic explanation, he managed to get the following phrases out, in several other languages other than my own: “been looking for this address for 3 hours”, “am totally lost”, “am from Romania”, “come from Holland”.

Still thinking about that movie, I figured it was time to show this Romanian man true Belgian hospitality. Using yet more sign language, I managed to get him to take his truck, and follow me in my car – while I was following the GPS to his destination. Once we arrived to the place, entirely in the middle of nowhere in some obscure ally in the Port of Antwerp, he was still lost. The company name his cargo was addressed to, was nowhere to be found. Lucky for him, in that same street is an emergency hospital, that is open 24/7. Since I, after nearly 30 minutes of die-hard interpretation, managed to understand where his cargo needed to go, I thought I’d go to the hospital and ask for directions.

Unfortunately, the only person there at that time, was performing some kind of surgery on a man having just injured his head. Thinking my timing could’ ve been worse (it could’ve been a woman having injured her head, for instance – in stead of a man), I asked this doctor where the heck this romanian guy had to be. He couldn’t point me in any sensible direction either, so I took my newly found Romanian buddy out for a walk, in the dark streets of the Port. We walked around the block, in search of his drop-off address.

He then managed to utter the word “coffee”, and pointed at his truck. Now that’s where he hit the motherload: coffee. As an IT-er, I know my coffee. I practically live off it. He had to deliver my sweet, sensitive and addictive coffee to one of these warehouses. We then walked the block again, but in a slighly different way: using our noses. We litterely sniffed the air. I guess it was around this point that I was starting to feel silly, walking around with a total stranger who doesn’t understand a word I say, inhaling deep breaths of air inside a Port. Death was imminent, I could feel it.

But then it struck us both: a soft smell of coffee entered our nostrels, and entered our minds. We could actually smell the warehouse, my plan had succeeded (granted, it was above all expectations). Two minutes later, we found the warehouse – which some genius forgot to label properly to get the company name on it.

All in all, we spent about 45 minutes searching his address. He had spent the last 3 hours in panic, because he did not deliver his cargo in time. He would’ve spent an entire night in panic, if I had decided to just go home. The moment that man saw his destination, it seemed like he could finally breath properly. He actually sighed with relief, and was truely, and sincerely, happy. Walking back to his truck, he showed me a map of the surroundings someone drew for him, so he could find directions. It contained about 3 lines, all highways not even remotely close to where we were.

I helped that man. From panic to happyness, in a mere 45 minutes. I dare challenge any shrink to do the same.

“Schools Kill Creativity”, by Ken Robinson

July 12th, 2009

Definately worth the watch.

Sir Ken Robinson makes an entertaining and profoundly moving case for creating an education system that nurtures (rather than undermines) creativity. (source)

You’ll lough out loud, and actually learn something about how our current education is limitating our powers of creativity. :-)

“Are we in control of our own decisions?”

May 30th, 2009

There’s a very interesting video on TED by Dan Ariely, which asks “Are we in control of our own decisions?“. It’s rather scientific, but definately worth viewing (it has some well thought off humor in it, too), because it reflects on our everyday behaviour as humans.

It also ties back to IT, and more specifically to (web) development. Halfway through, the question is asked why some countries experience larger organ donation numbers than others. Turns out, it’s the difference between the following two phrases.

  • Check this box if you want to participate in the organ donor program
  • Check this box if you don’t want to participate in the organ donor program

If you were to read the above two sentences quickly, without having those 2 words outlined in bold, you could easily be mistaken. People don’t like to tic checkboxes, as experience has shown them it usually gets them things they don’t want. How often have you accidentally signed up for a newsletter, when registering a new account? Or installed some toolbar, when installing a new program? Because our natural behaviour is reverted – and used against us.

It’s not the prettiets of ways, but the example above shows what can be accomplished by studying human behaviour.

The person who designs the form, will have a huge influence on what you’re doing.

That quote is more true, and definitely worth thinking about when creating new (web) applications. The way you design your form, the wording you choose and the options you present, will – in large part – control the outcome of that form. The same way you can guide a conversation to a particular ending, by choosing your words and phrases carefully, the same way you can control your visitor’s behaviour when using your application.

The video becomes even more interesting around 13 minutes in, where an example is given on choice. These were the three possible choices, and the user percentage that choose that particular option. It’s the ability to sign up for a (paid) subscription on a website.

  • Economist.com subscription (US $59.00): one year subscription to Economist.com, includes online access to all articles.  => 16%
  • Print subscription (US $125.00): one year subscription to the print edition of The Economist => 0%
  • Print & web subscription (US $125.00): one year subscription to the print edition of The Economist and online access to all articles. => 84%

The above makes sense, since the subscription itself was horrible. Why pay for the “Print subscription” option, if it costs the same as the “Print & web subscription”, but you get more from the latter? It’s only logical we choose the bottom option. After all, it gives us more for the same amount of money.

Logic dictates us that we could leave the middle option out, since it serves no purpose. Every sane being would choose the bottom option. These were the results when leaving out that middle option.

  • Economist.com subscription (US $59.00): one year subscription to Economist.com, includes online access to all articles.  => 68%
  • Print & web subscription (US $125.00): one year subscription to the print edition of The Economist and online access to all articles. => 32%

That’s a huge consequence. While the previous options showed a clear trend towards the latest option (the most expensive one) because it gave us the idea we could get more out of it for the same price, we negate that result by leaving the option out.

The option in the middle was useless in the sense that nobody wanted it, but it wasn’t useless in the sense that it helped people to figure out what they wanted. In fact, relative to the option in the middle, the last option looked like a fantastic deal.

We can manipulate our users’ behaviour more than I had thought. It’s obvious that an intuitive interface can help, but it’s now clear that putting some thought in your options, choices, words and phrasing can help get the target we want.

Creating Benjamin Button’s Face Through CGI

April 26th, 2009

A very impressive take on creating Benjamin Buttons face, using the most modern CGI known to man. Did you even realise the first hour of the movie was a completely computer animated face? Every action, reaction, motion and emotion of Brad Pitt’s face was interpreted by a computer, and transformed to a face which aged roughly 45 years. And it looked 100% real.

All in all, the movie A Curious Case of Benjamin Button is worth viewing, but especially so after watching that little making-off! Amazing what technology can accomplish these days …
