Our digital senses

In some of Adam Greenfield’s backpages “Whatever happened to serendipity?” he recounts how he used to scrounge for punk rock records and how the difficulty and uncertainty of the experience was part of what made it worthwhile:

But at the risk of sounding like an old man, this ritual – make no mistake, that’s what it was – invested the purchase with meaning and value for me, and I despair at a world that doesn’t at least offer the possibility of similar adventures to its inhabitants.

This resounds simply with the fact that things that are worth doing are oftentimes difficult to do or to learn and things that are worth having are the ones you invested effort in getting.

Just to narrow this down to music, 99% of the music I listen to has no meaning whatsoever to me. This has no bearing on the quality of contemporary music, which I think is actually quite high. Only a couple of albums and artists have managed to strike a chord with me that makes their music merit a repeat listen.

This may be different for others but the real investment of Fl. 45,– or so back then was quite significant, distribution channels were few and the diversity they offered near zero, you got your recommendations either from mass media or from word of mouth. The experience was radically different.

Yes, something has been lost in the transition but the abundance we have gained in return makes it more than worthwhile for me.

But the piece is about the loss of serendipity and shortly after he writes:

Yes, I suppose you could always switch the thing off, leave it behind, deliberately “forget” it. But when you’ve lived your entire life through the intercession of a mobile and benevolent Delphi, is that realistically an option? I suppose we’ll find out.

Having spent two and a half weeks in the United States most of which in and around San Francisco. I can testify that it is indeed not an option.

San Francisco is so well mapped within most online services that the experience you have there using the internet is unparalleled. Most services originate there which results in San Francisco being completely mapped in Google Maps, well covered in Yelp and there are ample Twinkling Twitter users in the proximity.

Unfortunately for a visiting European like myself it is prohibitively expensive to use roaming data, meaning that most of the time my iPhone was a multimedia brick. Being disconnected like this, made me acutely aware of how reliant I have become on the real and virtual compass my iPhone provides. Walking around without a continuous stream of data coming in on the iPhone felt as if a sense was missing.

What is a sense other than a mapping of external information to a part of your brain? The services on my iPhone provide me with a sense of presence and sense of direction within my spheres of contacts. My brain is conditioned to receive regular updates to this sense and withholding those updates used to be called something like “withdrawal from information addiction” but since this is a sense we’re talking about, I think “sensory deprivation” may be better suited. Without this sixth sense so much of your peripheral ‘vision’ is cut off that you feel like you are wandering around half blind.

Mailtjes naar publieke instellingen

Zoals ik gisteren schreef heb ik e-mails gestuurd over onze resultaten naar GroenLinks en Rover over de resultaten van de visualisaties van de reistijdengegevens.

Het is alemaal nog niet super-af maar het geeft een goede indruk van de verschillen in reistijd tussen openbaar vervoer en de auto. Als iemand interesse heeft in beelden die dit aantonen, dan zijn het wel deze instanties.

Hier de e-mail naar GroenLinks:


Ik zag van de week wat persberichten langskomen over openbaar vervoer e.d. Ik heb samen met een collega een tijdje geleden van 9292OV en van ANWB voor elke postcode in Nederland opgevraagd wat de reistijd is naar de Dam. Deze gegevens hebben we verwerkt in een serie visualisaties waarin duidelijk zichtbaar is hoeveel langer het kost om met het openbaar vervoer ergens te komen:

Een van de visualisaties laat zien hoeveel verder je in dezelfde tijd kunt komen met de auto:
Compare: travel by public transport or car

Uiteindelijk is er een interactieve applicatie uit voortgekomen die nog gepubliceerd moet worden:
It's hard to stop tweaking
Alle visualisaties:
Done, for now

En onze beider verslagen hoe we het gedaan

Er zijn hier twee punten die spelen:

1. Het verschil in bereikbaarheid tussen de auto en het openbaar vervoer zijn dramatisch en deze visualisaties proberen dat inzichtelijk te maken.

2. Het verkrijgen van de gegevens om dit soort inzichten te bereiken is goed mogelijk maar moeilijker dan het zou moeten zijn. Er zijn meer stimulansen nodig om gegevens vrij te geven en dan het liefst in herbruikbare formaten.

Ik hoop dat jullie er wat aan hebben.

Met vriendelijke groet,
Alper Çugun

Nu maar afwachten of er een reactie komt.

Update: En hier de reactie van de publieksdienst van GroenLinks:

Geachte heer/mevrouw Çugun,

Hartelijk dank voor uw e-mail van 6 september 2008 die wij in goede orde
hebben ontvangen.

Wij zullen uw punten meenemen in komende debatten.

Ik hoop u hiermee voldoende te hebben geïnformeerd.

Met vriendelijke groet,

Playing with Public (Transportation) Data

As promised a while back after we got our fill playing with the data I would release it to the public to see if you could come up with something interesting. I’d leaked the JSON file to Kars and he applied his skills in visualizing things in processing to the dataset.

Then after some more back and forth I retrieved a similar dataset from the ANWB site: the time to travel a similar distance at a similar time but this time by car.

The juxtaposition of those two datasets made for some interesting results and some nice applications of interactive filtering. Kars has a full writeup of his process.

So without further ado, here is the dataset under a Creative Commons Attribution license. It’s a JSON file: Traveltimes with as keys a four digit string for the postal code. The value is a dictionary with this key-value mapping:

Latitude GPS coordinate
Longitude GPS coordinate
Inferred name of the location
The time it takes using public transportation
The time it takes by car (a small amount of null values where the time could not be retrieved)

All times are from the center of the 4 digit postal code as well as can be determined to Dam Square in Amsterdam around noon on a given day.

I find it interesting (and somewhat appalling) to see how large the difference is between taking the car or going by public transportation. Doing a sampling for 08:00 on Monday morning during rush hour might somewhat equalize this, but I think it’s safe to say that car owners will remain at an advantage.

So next up is e-mailing GroenLinks and Rover to see if they can use this data or these visualizations.

Coworker.nl — Map of coworking spots in the Netherlands

Some ideas start out small and then grow larger than you thought imaginable. Coworker.nl is one such idea. This is a write up about how it came to be and how you can build your own.

As a wandering free agent, you end up in strange places and if you’re stuck somewhere, it could be useful to get some work done in the neighborhood. I was not the only person with this problem and I couldn’t find a good WiFi map either, so I thought we could start something up.

A conversation about coworking on Jaiku quickly turned into the idea to gather those locations onto a Google Map and see if we could make that work. So talking back and forth a bit, I made a custom Google Map and invited people to add their offices with drop-in coworking spaces on it. This took off a bit and we had a functioning coworking map of cool companies and startups in the Netherlands willing to host a nomadic worker. Robert had the domain coworker.nl lying around and he pasted the code for the map on that domain and Coworker.nl was born.

After some time, other people also started to add coffee shops with WiFi with a coffee cup icon and a public utility was born.

Coworker.nl - Coworking spots in The Netherlands


A lot of people have seen the map by now (22’000 and counting) and I have never launched a project as small as this which got so much attention in so little time. Robert and myself didn’t have any problems getting this featured in various publications and even in a national newspaper. This says something about the immediate appeal of a simple geo-visual application and about the climate in which we launched this.

coworking.pdf (1 page)

Independent web workers are seen as the vanguard of the hot Dutch new economy. Small shops, people setting up office in lunchrooms and coffee shops are seen as a ‘new’ trend. These workers also are in need of more flexible office space solutions (of which there are precious few in the Netherlands). Our map provides a handy visualization of this trend, it exactly fits a niche and appeals to people.

Values and Misconceptions

What differentiates this map from most other WiFi maps and other custom maps and geoapplications is its incredibly narrow focus based on a shared set of goals and values. The initial participants in the map all know on a near instinctive level what is meant by coworking. They understand the problem of needing a place to work and are willing to share their offices.

A lot of outsiders who find the map do not really get it and just a link to the Coworking wiki is not nearly enough to explain the shared values and history this map is built upon. Some people think we are an exchange for short-term office space, others want to sell their office space on a per day basis to make an extra buck. All interesting tangential applications of this map, and it’s nice that people are running with it, but we should stay true to the original goal.

The Tools

We should be really thankful of Google for providing these powerful and easy to use tools like Google Maps which we can use to hack something together in literally no time at all. We could have built our own database and map editor etc. but that would have taken some days if not weeks and would have greatly reduced the appeal of a small project such as this.

The fact that we could paste some minimal code to Jaiku and invite people to edit the map made all te difference. One additional step which would help in the management would be to add some kind of versioning or backup facility so if somebody accidentily deletes the entire map, I could easily restore it to a previous version.

The Data

The data is available as a KML file to anybody who wants it (feel free to take it, distributed backup is the best kind) and I think we’re willing to publish it under a Creative Commons Attribution-Share Alike license but I would appreciate it if you let us know if you’re going to build something.

Build your own local

Because this is so simple to setup local versions have already been made (Coworking São Paulo by Michel Zappa) by others but the vision is to eventually cover the entire world both with maps and locations one country at a time, so to get this started here’s a small recipe how to set this up:

  1. Create a custom Google Map
  2. Call out to your local scene on Twitter, Jaiku and whatnot to ask if they’re interested and if they have spaces they know.
  3. Invite these people to edit your Google Map, be sure to allow them to invite others as well to help your map grow virally.
  4. Get a (short and memorable) domain and paste the embed iframe code of the Google Map onto the domain for better visibility. You can also copy our CSS and JavaScript for extra ease.
  5. Let it grow. You don’t have to go about it too agressively, in our case we built it to scratch our own itch. Any value others derive from it is a plus.

Once enough countries have their own map, we may be able to combine them all into one massive global coworking map, for those people hopping countries.


There is some stuff which this map is not really about but wich bears talking about anyway:

The fact that the map also houses coffee shops with WiFi and a place to sit may not really be about coworking, but these are spots where you can get some work done and they show that there was no high quality WiFi wap for webworkersin the Netherlands. I expect this is the same in other countries.

Working area

There are quite some commercial spots available with meeting rooms and desks which you can lease by the day or some other period. These are not exactly in the coworking spirit, but they do serve a need, so for now we have allowed these to be on the map as well.

As I already wrote there’s a shortage of office space which you can lease flexibly. The map could be used to show policy makers and realtors in which regions of the Netherlands there’s demand for flexible office solutions and in the future we may add a vetted exchange to the map to help freelancers and small companies such as ourselves to get suitable office space.

Most of the people on the map are either free agents, people working in small companies, startups or a combination of these. So that way the map also serves as a list of interesting companies and people in the Netherlands who are active in the web scene and who have an open attitude. I think that is also a valuable thing to have for a nascent scene such as ours.

Socio-locational disconnection

I’ve been tremendously enjoying the stuff Jan Chipchase writes on his blog both current and digging deep into his archives. A dream job if ever there was one.

His current piece is especially pertinent as the iPhone 3G release with builtin GPS and accompanied unlimited data plans will herald the location based revolution. Many of my friends say that they do not want to broadcast where they are and know where their friends are most of the time. That they would rather get together using premediated consensual communication.

I think in user research you have to adopt the same maxim that everybody lies maybe unknowingly or unwillingly. It remains to be seen how many people will not succumb to the temptation of total information. Broadcasting your location, but even more attractive knowing where your loved ones are at any given moment. The same initial reaction to mobile telephony didn’t prevent everybody I know from getting a mobile phone.

What this will do to the mystery of travel and unknown locations is a whole different question asked by Babak. I think unequality in economic, communications and political circumstances will always keep parts of the world shrouded in mystery.

Workshop session on geodata visualization

Yesterday we had an afternoon of workshops in an unconference style event at the office. A full registration of the event with video and slides will be published during the course of this weekend, but unfortunately most of it will be in Dutch.

I did a hands on workshop of a small datavisualization project I did this week and I registered myself on video using Screenflow. The video (in Dutch) is below:

And the result:
Public Transportation Travel Times

I did not make a keynote instead opting to the more hands on presentation of narrated browser tabs interspersed with live demoes and code samples.

Here’s a list of the tabs I’ve used during the presentation.

Apple’s new iPhone

Today was a day of many happy occasions. The Dutch national soccer team utterly crushed the reigning world champion 3-0. And Steve Jobs held his annual WWDC address announcing a 3G iPhone for the masses.

Uploaded with plasq‘s Skitch!

“Twice as fast. Half the price.” Hell yeah. I will be getting me one. It’s been some two years since T-Mobile shafted me and I can’t exactly say that the other telcos in the Netherlands are worth a damn. Might as well go back for 2 years of servitude.

July 11th it is and no official price yet, but I will be queueing at the store.

Arduino Diecimila projectje

Het is al een tijdje geek-chique om te zeggen dat Arduino’s cool zijn en te wensen dat je de tijd had om ermee te spelen. Dat vond ik wat vrijblijvend worden, dus ik heb maar een starters-setje besteld.

Multi LED setup

Het idee is dat dit een simpel uitbreidbaar bord met processor is waar je een programma op kunt laden waarna dat zelfstandig kan draaien en de in- en uitvoer kan aansturen. Je kunt er allerlei dingen op aansluiten en een Arduino kan ook communiceren met andere Arduini of de server.

Wat doe je hier dan mee? Afgelopen week hield Adam Greenfield zijn presentatie op The Web and Beyond over de intelligente stad, en dat is één van de dingen die je hiermee kunt bouwen op kleine schaal. Het voorlopige idee is om op kantoor sensoren en/of displays te maken om de duizenden forensen die per dag passeren op de hoogte te brengen van iets.

Dat zou bijvoorbeeld de vertrektijd van de volgende trein kunnen zijn, of de actuele vervuiling op het moment. Het gaat er een beetje om wat goedkoop meetbaar en wat goedkoop weergeefbaar is.


Ik heb van mijn tripje naar Londen vorige week de aantekeningen over de eendaagse Geekyoto conferentie geplaatst op Four Starters. Geen vervanging voor de dag zelf, maar veel interessante weetjes en referenties.

Het is in het Engels en ik denk dat ik meer in het Engels ga schrijven, misschien ook op dit blog. Nederland is een te kleine vijver.
