Blog is back

2 09 2010

This is mostly a test post to verify that this blog actually works again. I’ve made the switch from hosting it on a dedicated Linux machine to and in the process messed up with the domain registration, got uninterested, was distracted by work, hobbies, and vacations. As a consequence, this website was unreachable for a while, but it should be back to normal now. Let me know if you notice anything out of the ordinary.

Incidentally, I would like to recommend my ex hosting provider, Bytemark, to anyone who might need dedicated Linux hosting. I switched to simply because I had abandoned some projects that required a full Linux server, and decided to keep only a blog, for the time being. Bytemark has always provided me with excellent reliability and outstanding support, so I wouldn’t have switched for any other reason.


Nikon D60 kit up for grabs

6 03 2010

Update: The D60 has now been sold, and the 55-200mm will be sold soon.

I am breaking a long silence on this blog for a short announcement. Activity on the blog will resume as soon as I have made up my mind about the direction it should go. I am considering abandoning all geeky topics and turning it into a photo blog or portfolio site, but I have more pressing things to do at the moment.

My Used Nikon D60 FOR SALE

In the meantime, due to my recent upgrade to a D90, I am selling my old D60 kit, with accessories.

This camera was bought in May, 2008 and is in near-perfect conditions. It has taken less than 10,000 photos, including most of those in my photostream.

It comes with the AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR kit lens, which is in near-perfect conditions as well.

I have the original packaging and all of the original accessories (battery, battery charger, lens caps, strap holder, cables, manuals, software, etc.).

I am adding the following bonus accessories to the pack:

  • 1 extra, original Nikon EL-EN9 battery
  • 1 2GB SanDisk Extreme III SDHC card
  • 1 Nikon ML-L3 remote
  • 1 Tiffen 52mm clear UV filter
  • 1 Hama shoulder bag
  • 1 mini tripod

The product is sold AS IS, with no warranties.

The price I am asking for the whole package is 350€/300£/450$ plus shipping. Payment via PayPal is appreciated.

In case anyone is interested, I might add a Nikkor AF-S DX VR 55-200mm f/4-5.6 G ED lens to the package.

Mail me if you need more information. More pictures here

Bullshit Graphs

28 05 2009

This is bullshit. You can tell it is bullshit by the fact that there is no unit declared for the Y axis and there is no credible source for all the data that is shown in this graph.


This is bullshit too. for exactly the same reasons.


Actually, the second is even more bullshit than the first. It’s been drawn by Vic Gundotra of Google and what does it show at the top of the curve of browser innovation? Google Chrome, how strange!

Alfresco Tech Talk Live @ 12pm EST, Friday May 15st, 2009

14 05 2009

Tomorrow I will be presenting our CMIS Explorer Portlet during this week’s episode of Alfresco Tech Talk Live. This is going to be a fairly technical talk, with lots of code thrown in for the developers’ benefit. If you want to know more about CMIS and how to leverage it in your Java applications, you should definitely listen.

To attend, please visit and enter the meeting room as a Guest. The talk will start at 12PM EST. I know, it’s 6PM on a Friday for us Central European folks, but I hope you won’t be all heading for the sea-side already.

You can find more information about TTL here.

Job-related updates

4 05 2009

Sourcesense LogoSince it’s been a while since I’ve posted anything about job-related events, here’s a recap of a number of things that made—or should have made—the news in the last few weeks.

First of all, we made a big splash by being named EMEA JBoss Partner of the Year at the Red Hat Summit in Malta, last April. Quite an achievement, I’d say, fueled in a not so small part by the dedication of our colleagues Luca and Piergiorgio, who have been named committers for the JBoss Portal project.

We are also ramping up our contributions to various Open Source communities. Let me just mention our OpenSSO connector for Alfresco, a project started by Gustavo that has just gone officially live on our new “forge”:

Finally, we are investing a lot of effort into this CMIS stuff that has everybody in the content management world interested. I personally got my feet wet with a 2-day “plug fest” that was held at Day Software’s headquarters, in Basel last week. Watching all those CMS vendors getting together to test the interoperability of their systems has been invigorating. Too bad nobody from either Microsoft or Oracle was there, but I guess getting approval for travel these days is not easy, so we will probably see them at a similar event in the US soon.

We are also going to get involved a lot in the new Apache Chemistry project that has just started its incubation phase at Apache. Stay tuned!

The ASF is 10 years old

27 03 2009

OK, this is old news, as the official birthday was yesterday, but yesterday I was too busy to write anything here. Actually I was busy having lunch with the person who personally signed the letter of incorporation, Roy T. Fielding. Curiously, neither of us was in Amsterdam, that’s how life goes sometimes. This would have been my first ApacheCon as an ASF member, so I’m a bit sad about not having been able to join the celebrations, but Happy Birthday Apache! anyway.

10 Years of Apache

On a related note, today’s meme is “my first message to an Apache list”. Mine was on Jul 7, 2000 (as documented here). This means that next year will mark the 10th birthday of my first participation (however minor) to an Apache project.

Ultra-wide zoom shoot-out

11 02 2009

I am looking for an ultra-wide angle lens for my Nikon D60 to complement my current collection of lenses. I currently own the 18-55mm VR kit lens and the 55-200mm VR as well, so I am pretty well covered above 18mm. I also have a collection of old, pre-AI, prime lenses, including a 50mm f/1.4 which is great for low-light situations, despite being fully manual and no metering.

I wouldn’t mind also getting the just announced 35mm f/1.8 AF-S lens. At a list price of $200 (or a little more than 200€) it’s going to be the best choice for D40/D40x/D60 owners wanting a fast prime which auto-focuses on their bodies. I will buy it, eventually, but not now.

What I want now is wide, very wide. I want something that goes much wider than the 18 mm of the kit lens to take some extreme shots meant to totally draw the viewer into the picture. Also, I don’t want a fisheye.

Sigma_10-20.jpgFor a while, I was eyeing the venerable Sigma 10-20mm. This has long been the default choice for people looking for an ultra-wide angle zoom to put on their low-range DSLRs. It was until recently the only one going down to 10 mm, it has an internal focusing motor, decent image quality, and an affordable price. Therefore I started saving pennies and planning to buy one as a Christmas or birthday present to myself.

Tokina_11-16.jpgBut just when I was about to grab it from a shelf or order it online, there came the Tokina ATX 116 PRO onto my radar. This lens has got some truly excellent reviews. Looks like its sharpness and image quality are top-notch and its maximum aperture is 2.8 all over the range, which is unmatched and great for low-light situations.

Its main drawbacks are the lack of an on-board focusing motor (but depth of field is so large at these focal lengths that this should not be a problem in practice) and its slightly higher price compared to the Sigma. Anyway, after reading reviews like Ken Rockwell’s, the decision was made, but I soon discovered that this lens is very hard to find, unless you are prepared to spend much more than the price it would have if it weren’t in such a demand. To put it bluntly, I don’t want to spend more than 500€ on it and I have a couple of local shops who would sell it to me at less than that…if only they had one in stock!

Tamron_10-24.jpgSo, while I am here hoping a Tokina turns up on a nearby shelf soon, I notice a review of the Tamron 10-24mm on This looks like a sweet lens also, it has a focusing motor, the largest zoom range of them all, a decent price and shouldn’t be hard to procure. The reviewer points out that it’s a bit too soft in the corners and maximum aperture is only f/3.5-4.5, but it’s a step above the Sigma anyway. On the other hand, the luminosity and sharpness of the Tokina still make it my preferred choice, but if I have to wait too much, the pendulum might swing once again.

What would you do, dear readers, if you were me?
