How I learned to stop worrying and love the bomb

Tuesday, May 25th, 2010

It happened unconsciously somewhere in the recent past, but for a while now I have been ignoring traditional media. Ignoring is not the right word: it implies an active deed on my part, but it is nothing like that. Somehow, traditional media just lost me, or I lost traditional media. Newspapers, television broadcasts, they are just no part of my life anymore. Somehow, they have vanished. Gone over the horizon. And it has been an improvement, to say the least.

Sometimes, I hear people talking about ‘the news’. Stuff that happens miles and miles away. I remember the days I used to care about all the injustice in the world. The troubled days, I must add. It was such a burden. Today, I hear something about a revolution here, an oil-spill there, but it has no meaning anymore. I can let it pass without getting worked up over it. As long as there is no oil on my doorstep, how does it influence me?

Even though I live next door to the Dutch parliament, the political arena is reduced to a virtual reality. An amusement show that has no bearing on my self. No matter what they do, what they decide, I will always be me. Wilders, a demon to some, a saviour to others, is merely a clown on the stage of this comedy. He does not bother me. Is not real.

It may come across as a little ego-centric, to say the least. But stop and think, the reverse is actually true! Who am I to think that all those far-away injustices concern me. Who am I to think I have anything to do with it, that I somehow have a role in bringing about, changing or correcting those circumstances. How ego-centric is that??

The important news will come to me anyway, through the people I know. The real world that surrounds me. And then I will be able to act, to change reality. That which I cannot change is not a part of my reality. And that which I change, is my reality. Always and constantly.

I perceive, I act, I change.

I have no past, no future, just the here and now.

Terabyte dinner device workshop, may 29th

Sunday, May 9th, 2010

On May 29th, 2010 the terabyte dinner device project invites interested parties to Revelation Space in The Hague, NL for a brainstorming and kick-off workshop to design the citizens answer to ACTA, internet monitoring, content filtering, net neutrality sabotage, criminalization of various behaviour and technology related to downloading and other dangers to the free exchange of content. We are taking the flow of information off-line again, out of reach of the content conglomerates. The return of the sneakernet, 2.0 stylee!

Invite some friends over for a nice meal, have them bring an external 1TB hard-drive each and hook them up to your Terabyte Dinner Device. Enjoy the food and the company, and when the evening ends each of you will have at least 750GB of new content, software or literature. All in crisp digital quality. And without leaving a trace that might implicate you for committing the horrendous crime of exchanging information.

At the eth0 summer event in August 2010 participants are invited to built their own TBDD, after which the first terabyte dinners may take place right there and then! Some of the more important design goals: easy to use (even your grandmother should be able to organise a terabyte dinner), using off-the-shelf components, easy to assemble, low energy consumption for terabyte picknicks in the park and a small form factor for maximum portability.

More information about the project, initiated by Revelation Space, the Hxx foundation and eth0, can be found on the revspace wiki.

If you are into embedded systems, electronics, product design, user interaction or just have a creative mind in general, please come over and join the revolution in content sharing!

When: May 29th, 2010, 14:00 hours.

Where: Revelation Space, The Hague, NL

picp and the 18F4550

Wednesday, January 13th, 2010

For a while i’ve been playing with microchip PIC chips. I have an olimex PIC-MCP-USB programmer which I use with picp under linux, and recently ran into some problems with 18F4550 chips. It would program just fine, but not erase the memory properly (took me a while to figure that out!). So I installed mplab on a windows machine, and sniffed the sequence of bytes going over the wire. Just for anyone who is fooling around with this as well, here is the proper picdevrc entry for the 18F4550:
