Paint, more paint and a bit of Gamma

I was out hunting for paint this week. I’m heading to Italy tomorrow to spend Easter there doing some work on the house. We’ve made some appointments with the local carpenter, the guy installing heating systems and we’re going to paint the floor of the attic. I’ve already done a large part of that, but ran out of paint last time I was there.

Since I bought the paint in Holland (paint and things like that are amazingly expensive in Italy for some obscure reason), I had to get the same brand again (colour differences always screw you over I’ve learnt in the past, so the brand really is important) and yesterday I went by the Gamma (a well-known Dutch shop for things like paint, and other DIY gear). They didn’t have cans in the size I looked for, but boy what a service. They literally called up all the other Gamma stores in the area for my and found out they were out of stock as well. Well, that’s wrong Gamma, just plain wrong. But really, the service rocked. I waited until today so they could maybe get a shipment. In the end, the didn’t, but again, while I was on my way from Amsterdam to Utrecht in my car, they called up all the shops in the vicinity for me to ask which stores still had cans in a smaller size. Three stores had some of those cans, so tonight between 8pm and 9pm I raced by all these stores in all different areas of the city and got myself 11 cans, in total almost 8.5 liters worth of paint. That should do the trick.

Other than Gamma helping me out with all the different locations that still had the paint that I wanted, I noticed the people at the stores were all so incredibly friendly and helpful, it was almost out of this world (or, this country). I still remember a time when I came back from the States (they pretty much invented the whole term customer service) and I was pretty annoyed with the terrible service you get here in the Netherlands. Well, I have to say: the Gamma is at least one exception to that rule. One piece of advice though: restock the paint department!

Tomorrow I’m flying out with all the paint in my suitcase. Fortunately I’m allowed 30 kilos of luggage, due to my flying pretty often, so I guess the weight won’t be that big of a deal. I can imagine myself taking on the paint in the hand luggage… ‘Sir, did you pack any liquids?’ :-)

Selling Agile Projects Part I – Setting the Stage

I blogged over at the JTeam Blog about selling agile projects

I’m by the way not sure if I should keep on mirroring posts here, or maybe just post a link like I’m doing right now. Or maybe even not do anything at all about my posts on the JTeam Blog…

Well, time (or comments) will tell.

My (re)start with JTeam

As I told you about a month ago, I quit SpringSource, or at least, quit being actively involved as an employee. It was time to move on after having been there since the beginning and having gone through quite a lot of challenges and having worked with so many great people there.

There are two simple reasons for my leaving SpringSource: although the work i did was very exciting, I dearly missed the entrepreneurial aspects in my work and on top of that, although we have a great team at SpringSource, not being able to work side by side with them (I was mainly attending and speaking at conferences, educating people and consulting for clients the last 2 years) kind of bugged me.

When I was in Israel right before the turn of the year, I was lucky enough to attend a great end of year party at a company called AlphaCSP. They’re a great bunch of guys doing really cool stuff and when thinking things over in between Christmas and New Year’s I came to the conclusion that I wanted to be involved with JTeam again.

Joost van de Wijgerd and I started JTeam in 2002 after we had both left SmartHaven, a startup focusing on knowledge management solutions. At first we wanted to call our company The A-Team but quickly decided that would be a little corny, so settled on JTeam as the alternative. After all, the main thing we did was Java.

The idea about what we were planning to with JTeam was (and still is) quite simple:

  • build great solutions for customers using state-of-the-art technology,
  • in everything we do exceed the expectations of our customers and
  • tell the world about what we’re doing.

I can say we succeeded in quite a lot of ways. Since the beginning of 2002, we build quite a number of solutions that have satisfied our customers. On a quite a number of occasions, we exceeded the expectations clients had of those solutions and of the service we are offering and with plenty of people blogging on their personal blogs, writing articles and speaking at conferences, we’ve let the world know we’re there.

The fact that JTeam has continued to do this, although both Joost quit being actively involved on a day-to-day basis starting early mid 2005 or so really satisfies me and I’m very happy that I can be part of this team again. I won’t be involved with JTeam on a full-time basis. I have a list that has some things on it that have been there for way too long already and it the time I’m not working at JTeam’s, I’ll be focusing on some of the items on that list. More about these things later on.

At JTeam, my title officially is Strategic Advisor. This is the result of endless hours of brainstorming about it (not). After first coming up with things like Chief Janitor (I would have liked this myself, but I really am going to more than cleaning the toilets) and Java Guru (yeah, I might know a thing or two about Java, but I think there are people at JTeam that know more in the meantime) we settled for Strategic Advisor. I’m still not really sure what that means. What I do know is that it feels good to be part of this team again and to work with the team to improve the stuff we do even more.

What will I be doing? Well, after having been at JTeam for little over a month now, I can say I haven’t had much time to do serious coding nor do I expect to be doing any of that in the near future. I’ll be mainly focusing on helping clients get more out of JTeam and the technologies we use at JTeam to build all these great solutions.

Of course I have gained quite a lot of experiences during my time at SpringSource with the development of software in an community-driven way, and this experience is definitely something I’m going to use on a day-to-day basis. As Leonard blogged last week the Dutch government has actively started to adopt open source software the last few years and I’ve already had some very fruitful discussions the last few weeks with clients of JTeam about this.

I’ve mirrored this post also on our company blog, to be found at blog.jteam.nl. This is where you will find more posts related to my work at JTeam. If you’re interested in what I’m up to there, please subscribe to that blog too…

Community-based innovation follow-up

As a follow-up on the post I did about Apple and whether or not they did community-driven development too, I did some more research and came across an interesting article by Johan Füller, Michael Bartl, Holger Ernst and Hans Mühlbacher. The paper titles Community Based Innovation: How to Integrate Members of Virtual Communities into New Product Development is an interesting essay about the ideas behind using a community larger than just the people employed by a company into the development of new products.

Obviously open source development is a very good example of integrating virtual (or online) communities into the development of new products. Using online communities of developers looking at your products all the time (by testing them, criticizing them, getting feature requests out there and advocating the products) open source projects such as Linux, Apache and also Spring have effectively used techniques described in the paper to get to better products.

The paper takes an interesting view point: using various case studies of for example Procter and Gamble and Audi they show how traditional companies have applied the ideas of community based innovation to the development of products other than software.

It’s interesting to look at open source development from this angle. What’s important about open source development: is it the fact about the source being open, or is it the idea of communities being involved in the development and as a result of that making software better? To my mind, the fact that the communities are involved in the development of the products from the early start makes the software better, leads to lesser bugs and better customer (developer) satisfaction. Sure, the fact that the source is open is important to a certain extent. After all, our clients are developers too and using their skills to not only look at the products as a black box, but also allowing them to look inside is a very good way of getting people more involved. The community aspect however is what’s most important to me.

What I’m asking myself currently is how many open source communities really realize this. How much do they know that the community is what makes their products better than proprietary software. How (pro)actively are they involving communities into the development of the product. The paper offers some interesting insight into how traditional companies did this and maybe the open source communities could learn something from this. Highly recommended reading material for any open source developer that looks beyond just delivering code.

What do you think?

JavaDay Roma: an typical Italian ad

I’m speaking at the JavaDay in Rome early next year. The event takes places on the 24th of January. I came across their website just now and this ad struck me as typical Italian.

Also, Andrea del Bene ha scritto: are you planning to give your talk (”Spring == XML therefore Spring == Sucks??”) in Italian?

Andrea: ahhhh, parlare di Spring in Italiano?? Penso di no :-) … Come se dice Dependency Injection in Italiano, iniezione di dependenze? Hmmm, I don’t think it’s gonna work :-) .

Anyway, looking forward to seeing all of you in Roma!

MyC4–an analysis

Earlier this year I started to participate in MyC4, an online community of lenders and borrowers with the main goal to eradicate poverty before 2015 (one of the United Nations Millennium Development Goals). The main idea of MyC4 is to bring together borrowers (from third-world countries in Africa) and lenders (mainly from the Western world) on a platform where using an auction-based system loans are set up.

The way MyC4 works

As a borrower you can set up your request for a loan through an intermediate in the local country (Ivory Coast for example or Uganda). Next, the auctioning system makes the lenders bid on the loan by providing a desired amount they want to contribute to the loan and a desired interest rate. The loan is disbursed to the borrower by providing the money from the lenders that provided the most attractive bids (for the borrower that is). The entire auctioning-process is handled online, which surely has helped MyC4 enormously.

I think this is a wonderful idea. It’s a market-based system that should (well, that’s obviously a bit ironic to say these days) assess what risk is involved in lending and incorporate any extra interest to compensate for the risk. Moreover, this way, it’s beginning to get interesting to ‘invest in saving the world’ you could say as lending to third-world countries (or rather people living in these countries) can start to be an alternative to putting your money in the bank.

Performance since I joined

Okay, enough about the good and bad of micro-financing in general; that’s not the reason I’m writing this. Before I get on to what I really have to say about MyC4, let me first give you some numbers:

Uploaded since March 08 €2,417.02
Available in account €38.07
Pending bids €40.00
Outstanding principal €2,398.44
Outstanding interest €184.18
~ projected ROI 10.08%
Total investments 44
Late / defaulted 5 / 0

First-class idea, third-world implementation

The idea is first-class; providing an auction-based system whereby the lenders can themselves specify which interest rate they’d like to get for the money they lend and based on the best interest rates (for the borrower) the loan is disbursed. The online execution however is poor at best. There are a few areas in which MyC4 should improve, will it ever achieve serious adoption. Many of these things (mostly related to risk-management, correctness of information, et cetera) are already covered over at P2P-banking.com and are definitely important to look at while judging if MyC4 will succeed. I will not cover those here however. Instead, I’d like to stick to the more user-experience focused areas and those that will drive adoption from a non-financial point of view.

Open up your data

We live in an era of open software, open platforms and open communication (people sometimes called that Web 2.0). MyC4 should open up and allow for easy integration of MyC4 borrower and lender data and operations into third-party applications. This is what Google Maps does for map-related data, eBay for auctions and Amazon for music, books and all kinds of other products. Apart from that there are plenty of other initiatives that do this. The web nowadays cannot function anymore without the so-called mashups.

Opening up would mean it’s likely far more people will be exposed to MyC4 data, loans, borrowers, lenders and the idea as a whole, thus attracting more capital. Opening up in practice means providing an API that other sites can easily integrate with. This is not rocket-science.

MyC4 should allow third parties to integrate with their site by providing means to do this. One can think about adding a Facebook app for example.

Speak up

MyC4 has frequently been criticized for its lack of communications. If there is something positive to say about MyC4, the site is immediately updated, as far as negative news is concerned, the MyC4 guys are mostly completely silent. This was most evident in the Ivory Coast affair, more thoroughly documented in forum thread. People reacted quite shocked when somebody named Githa Kurdahl, an intern at MyC4 was the first to (not even on behalf of MyC4 but just because she couldn’t stand the silence anymore) open up about this rather itchy affair at the MyC4 platform that affected many lenders (including myself). Frequent suggestions to the MyC4 team to communicate more and more openly about what’s going on are left unanswered and as explanation MyC4 uses the lack of internet in third-world countries where at the time, they’re attending a conference.

MyC4 should communicate much more openly and enter into a real discussion with their lenders. These provide the money after all. The nature of most lenders over at MyC4 is pretty philanthropic (even though most want to make some money too I guess) and would love to help out improving the platform.

Clarity and correctness of data

In a number of areas MyC4 displays incorrect or vague data. In the front page for example after you’ve logged on, you’re seeing your average interest rate. This is calculated over all loans and does not take into account the fact that money pending disbursement does not add to capital growth and money left in your account neither.

As you can see, MyC4 states the average interest rate for me is 13.8%, while (as previously shown), projected ROI is 10.08%. While of course technically correct (the average rate over all investment indeed is 13.8%), this is obviously not what I’m interested in. Putting it differently: if I invest €5,00 in an investment that gives me 20% interest and I leave the remaining €95,00 in my account doing nothing, is my average interest rate still 20%?

Mind the details

There are a few details that are thoroughly overlooked in MyC4. One is security. At the moment your password is sent over plain HTTP, which means virtually anybody can intercept it. While it is possible to send it over a secure channel, but this is not the default, which it should be!

Other than that, the way the login form is created makes it impossible or harder at a minimum to save usernames and password in password managers such as 1Password. This is also not very user-friendly.

Other than that, the site is plain slow in some areas, which doesn’t help either. The forums are not very user friendly either.

Technically speaking, MyC4 should get their act together. The site is a big mess now and it does not really show any sign of improving.

Open source?

Many people have chimed in in various discussions around the MyC4 platform and many asked if the platform could be open sourced. I think this is an excellent idea. Open sourcing makes sense, as long as the platform itself is not a competitive advantage. In MyC4’s case (whose main business is helping eradicate poverty by 2015), the competitive advantage (if you’d even want to speak about one) is the community of borrowers, lenders and providers (the intermediates between borrowers and lenders), not (source code to) the platform itself. MyC4 would be way better off open sourcing the platform to encourage anybody to help improve it. Obviously the choice for the Microsoft platform does influence the possibilities here, but that’s no reason to forget about it entirely.

Concluding…

Concluding, I can say that I’m absolutely thrilled to see initiatives like MyC4 start and I absolutely believe in the idea of making eradication of poverty real business. We live in a market-driven, capitalist world whereby anything turned into real business and offering real ROIs will attract investors. This is what happens with MyC4. The platform however is not ready for serious adoption by the mainstream masses. If executed better, this can be very big. KIVA.org recently crossed the $50M mark for example while MyC4 is only still at approximately $5.5M. KIVA.org does not give lenders interest, which gives MyC4 such a big advantage IMO.

Especially in an initiative where the online part of the community is absolutely vital for success, it’s a shame the online platform doesn’t get a whole lot of attention. So many possibilities… I wish I had a little bit of time left…

Food, kites, books, computers and music

No, those are not the essential things in life… It’s what kept me busy today though.

I started out today by doing lots of stuff in front the computer, from reviewing documents, to setting up training material, to preparing presentations and more stuff like that. At 4.30 I kind of was a bit tired of it and went out for a while. I figured I should get some books. I’m starting a world tour in a few days (well, that’s maybe exaggerating it a little bit, but I will be traveling quite a bit the next few weeks) so there was a definite need for some reading material. I got myself the following books:

Then as I walked home, I decided to take a different route and came across a new take-out place creatively called the Food Shop. It’s on the Oude Gracht opposite the Rembrandt Cinema. I’m eating the food they prepared for me as we speak (still busy reviewing some documents) and it’s quite good. There was some potato gratin, beef stew with onions and tomotoes and some mixed grilled veggies and a salad. Pretty edible :-)

Last but not least in about an hour, I’m heading towards Laren, to have one of my kites repaired. Tomorrow the winds are blowing again (about 20 knots) and although I won’t be able to use my 8sqm I guess, I still have to have it repaired after I ripped it a bit… The place I’m heading is called Kitereparatie.nl. It’s just a guy who’s good at fixing kites…

In the meantime, Boards of Canada started playing, which reminds me of the last few songs I heard on Last.FM. I subscribed to Last.FM by the way. It doesn’t bring you a whole lot, apart from your loves songs now being a radio station you can listen to, but well, I think the service is really useful, so I’ll gladly pay up.

Tonight I’m not going to do a whole lot. I’m going to have a few beers with Jack (a friend of mine). Tomorrow it’s kiting day. I’ll also drop by at my parents. They just got back from a holiday and then I’ll be going to Amsterdam to have a few drinks there… On Sunday, I’ll probably do some kiting again and later in the day, I’ll fly to Copenhagen. Denmark and Sweden, that’s what it’s going to be this week.

  • Electric President – Hum
  • Piana – Winter Sleep
  • – cool Japanese ambient music

  • John Afterglow – Raw Like Sushi
  • – some really cool Swedish electro!

Trying out water-proof camera to… prepare a curry

Well, since I forgot to use the camera this weekend and still wanted to try it out, I decided to prepare myself a curry and record it. Of course, I was inspired by the Man with the Pan, whom I can never equal in his videos, but then again, I did have some fun with my knives, veggies, chicken and pan. Maybe I’ll do this again if I feel like it. I do have to get myself a higher quality camera though, this really sucks for videos like those. But for now it works… And I guess as a water-proof shock-proof camera when kite boarding, it’s great too :-)

Here’s the result:

If you want to make this classic and quite tasty curry yourself, it’s quite easy.

For the sauce you need

  • A small onion (I used red, but you don’t have to)
  • Fresh or frozen galanga (or ginger as an alternative), about a quarter of a cup
  • Some freshly ground pepper (about one or two tablespoon)
  • 6 cloves of garlic
  • 6 (ideally kaffir) lime leaves, snipped into small slivers with scissors for example (not shown in the video)
  • 1 tablespoon of chili powder
  • 1 or 2 fresh read chilies (depending on how hot you want it)
  • juice of about half a lime or lemon
  • 1 teaspoon of shrimp paste
  • 3 tablespoons of fish sauce
  • About half al liter of coconut milk
  • If the sauce ends up not sweet enough, a bit of brown sugar

The easiest to prepare the sauce is to put all ingredients in a food processor and process them to form a sauce.

Then you can use a wok. I usually just use a frying pan, as it’s a easier to handle :-) in my small kitchen. Just cook the chicken a bit (2 or 3 minutes). Pour the sauce on top of the chicken, put two or three diced tomatoes on top of it and let this simmer for about 45 minutes. When done, serve with rice and plenty of cilantro. I usually have a sweet and sour cucumber salad with it, that’s wonderful…

If your sauce (after having cooked for 45 mins) is not tasty enough, add some more chili to make it spicier, a bit of brown sugar to make it sweeter or a bit of fish sauce (be careful with this though) to make it more salty.

Bon apetit!

Another great session yesterday

I’m sitting at home at the moment, being chilly and all. I hoped to get off to an early start today to do some kiting in the late afternoon. Well, I did get up at 6′ish, but didn’t quite hold out the entire day. I think the sessions last weekend were kind of a bit too much, to say the least. Will have to take it easy for a couple of days. Fortunately no courses this week, only internal work to do.

Anyway, Lars, Marc and I got some good kiting done yesterday. We went to the beach at around 2′ish. It wasn’t such a long session (we stayed until 5.30 or so), but it was good. I also bumped into Jeroen, one of the guys working Telstar, the kite shop where I usually buy my gear. He was out on the water for the second time after having revalidated from braking his back in 6(!) places. While holding his 12sqm 2009 Gaastra Jekyll to the ground he said the winds were not blowing hard enough yet. Can you imagine I was out with my 8sqm? Well, in his defense, he had shortened his lines, which gives you a bit less power in your kite.

Anyway, Jeroen and friends were doing some great tricks of which I took a few pictures. There are also some pictures of me making a couple of airs. It’s not that brutal yet, but I’m getting there… Also, this was the 8sqm and the current really kept me from picking up serious speed and thus higher airs (but well, those are just excuses :-) ).

After wrapping up Lars and I had pancakes in a very traditional Dutch restaurant in Heemstede. We both finished almost two and a salad. I don’t I’ve ever eaten that much pancake in one day…

More pictures by the way in the corresponding Picasa web gallery. The guy in the white Mystic lycra; that’s me…

It’s autumn again!!

Yesterday Lars and I had a great session at Wijk aan Zee. Unfortunately the wind was a little too light to go upwind with my 8sqm, so I had to take the 12sqm. The power in this kite is big and the bar pressure is a bit on the heavy side. So when I got out my 8sqm later in the afternoon, it was a breeze going in and out against the waves.

It was blowing about 18 to 20 knots in the afternoon from west-south-westerly direction. The swell came from the same direction and that’s always when things start to get a bit messy… But all and all it was a good, intense and long session. Started at 1.30pm and quit at about 6pm.

This afternoon it is supposed to blow a little more, so that’ll definitely be enough for the 8sqm! I’m heading out in half an hour. I think I’ll use my new bar. I have two Gaastra kites that use the same bar. The bar that I used up until now starts to get a bit quirky, so I’ll switch to the new bar.

Tomorrow also should be great. I think I’ll get up to an early start tomorrow to be able to do some serious kiting in the afternoon, with winds approaching 30 knots…
