Inspirational words from Steve Jobs (2005)

March 12, 2010

Nothing wrong with some breakfast for thought. Take a few minutes. Sit back. Listen.

Steve Jobs gives a speech to the graduates of Stanford University in 2005.

I’m pretty harsh on Apple’s strategies, and therefore negatively biased towards Steve Jobs. This speech gives it some balance.

Thanks for the link to JP from Reflect7, who wrote an interesting article on why not to base your business solely on the iPhone.


Convert and compress Flip video on Linux with ffmpeg

January 14, 2010

A quick note to make sure I won’t forget how I did it:
ffmpeg -i hedde-soul_singing.mp4 -acodec mp2 hedde-soul_singing-compressed.mp4

Reduced my 15 second Flip UltraHD movie in mp4 format from 13.8 MB to 2 MB.

The results:

FFMPEG compressed (2 MB)

Original (13.8 MB)

Effective use of social media tools

June 28, 2009

This news item shows how social media tools can be applied to reconstruct dramatic events. It’s an enlightening example of accidental collaboration using mobile phones and services such as Twitter.

Vodpod videos no longer available.

Needless to say: we had a good laugh.

Open up for OpenID

March 24, 2008

One up for Michael Arrington:

It’s time for these companies to do what’s right for the users and fully adopt OpenID as relying parties. That doesn’t fit in with their strategy of owning the identity of as many Internet users as possible, but it certainly fits in with the Internet’s very serious need for an open, distributed and secure single log in system (OpenID is all three).

With “these companies” referring to AOL, Google, Microsoft and Yahoo!. I couldn’t agree more.

Via Twitter announcement

February 29, 2008

Lijst is something I’ve had on my mind for years. The concept evolved. Today I think it is mature enough to be announced:

Feedback is highly appreciated.

My affair with Zope3

February 24, 2008

When Martijn Faassen introduced me to Zope3 in December 2004, something happened. I fell for her logic, her view on the future. Her looks were promising. We quickly partnered in a small project I was working on.

Then things started to get messy. Evenings of joy turned into evenings of long, frustrating conversations. She just wouldn’t dance with me anymore. She complained about my lack of understanding.

Last week I received Philipp’s updated Zope counseling guide. A fresh impulse to give our relation a second chance. Hopefully Philipp will assist me in understanding her better.

On first sight things seem promising. Zope3 let go some of her complexness and grew a bit more mature. Let’s see if we can get to dancing again!

XML Topic Maps explained

January 9, 2008

The semantic web has been above my radar for some time now. Still I find it hard to grasp the available standards. My focus has been primarily on XTM (XML Topic Maps). Sure, I’ve read the TAO and played around with online examples. I even presented the concepts of the semantic web to 20 non-tech colleagues.

But… crafting a nifty simple XTM document myself? Not yet. It’s verbose. It’s hard.

Tonight, I found an apprehensive introduction: The Topic Maps Handbook (pdf). Pages 12 to 15 will get you up to speed with your first XTM. I chose ATC definitions as a domain for my topic map (see below). It’s a start.

Next step is visualization. I’m considering XSLT => dot => PNG. More on that later, if I succeed.

Larry Lessigs brilliant case for new media

November 22, 2007

I was touched by this plea for common sense in legislation for distribution of digital products and user generated content.

Hack at home

October 12, 2007

Paul Graham in How to start a startup:

“Ever notice how much easier it is to hack at home than at work? So why not make work more like home?”

“I think hiring people is the worst thing a company can do. To start with, people are a recurring expense, which is the worst kind. […] worst of all, they slow you down: instead of sticking your head in someone’s office and checking out an idea with them, eight people have to have a meeting about it.”
