Arno x2

One week ago, I took a photo of my colleague Arno with my Olympus E-PL5 and its 14-42mm “kit” lens set to 17mm. That small zoom lens opens up to f/3.8 at this focal length. Looked like this:


And today, I took almost the same photo of him, but this time I used my Olympus E-M10 (different camera but same sensor) with the Panasonic Leica 25mm/1.4 lens fully opened to f/1.4, which then looks like this:


Both are in-camera black & whites, with a simulated orange filter (at least this is what I’ve set when converting them from the raw .orf files using Olympus Viewer 3).

I like both. 17mm shows a bit more surrounding, while 25mm concentrates more on the subject. And of course the wider aperture of the prime lens blurs the background more than the zoom can do. But I also like the reflection of the Deutsche Bank building in the first picture, so it will take some time to decide whether I prefer one of these over the other.

Thanks for viewing.


It all began when my colleague Arno asked me about a camera. And this time his question was about a real camera, a Sony A6000.

Well, I told him, that one is at least as good as mine – its autofocus should be way faster especially on moving subjects, the sensor is APS-C, so a bit bigger, dynamic range could be better, whatever – you know the drill. No built in image stabilization was the only contra argument I could memorize without comparing actual spec sheets. Oh, and – how many – 20 Megapixels? Anyhow, more than enough of these as well. The fact that it’s not too expensive – in the same ballpark like an E-M10 or -Mark2 – was an additional plus. Everybody’s darling, I told him, and that he should get one if he saw a good offer.

A week went by, then another one, and finally I asked if he bought it, and he said no. He still wanted to make financial plans for this year together with his CFO 😉

In the end I decided to lend him my Olympus E-PL5 together with its kit zoom and the VF-2 electronic viewfinder. That would still leave the E-M10 in my bag, so I could live with that for a while.

Well, it never actually happened. He was about to take the camera – which he put into a bag first – into his car after having a smoke together with me, but he forgot to take his car keys, so we stood outside, smoking, bag with camera in his hand.

“See?”, he asked, adding “I guess I would never take that camera with me, it’s just too big, you cannot put it into a pocket, so it would probably stay at home all of the time”.

Ok I thought, thinking about alternatives. If my camera was out of the game, then so was the A6000 he had asked about, and I recommended a Sony RX-100 instead.

“Ask Basti”, I said, “he has one. First generation, they should be quite affordable by now”. Short internet check when we were up again – yep, slightly above 300€, fits. And Basti offered to bring his camera as well, so Arno could have a look before making a decision.

And that is what happened today. “Perfect”, was Arno’s comment, “that is the camera I want”. And so during our lunch break we took some photos:


Cameraman (my colleague Arno, trying Basti’s – or Nadine’s? – camera on me)

He really seemed to like that thing. While I took one photo of him, he took three of me (and several more):




Don’t directly compare these with the one I took. The Sony pictures are out of camera, while I “developed” mine from the Olympus raw file (.orf). Plus I had the 45mm/1.8 M.Zuiko lens on my camera – the Sony has a very good Zeiss zoom, but it can’t be opened that wide – and it’s of course way shorter to fit the 1″ sensor inside that camera.

Still, pretty good detail as far as I can tell – and these should have detail, 20 Megapixels of them. More than enough, like I told him.

Always glad if I can help. And thanks to Nadine and Basti who helped as well.

Thanks for reading.

My (email-) interview with Ian Murdock, from 2006

After reading the news about Ian Murdock’s death and the follow-up mournings of the greater Debian community I remembered that I actually met him, talked to him, and even email-interviewed him in 2006. I haven’t searched my old blog databases for that because there was a time we didn’t backup and lost bits of it. But I still have the original email with his answers to my questions. Remember that this is 10 years ago, so it’s not about the current stable version 8.x (“Jessie”) of Debian, but about older stuff.

Anyway, here’s his answer mail with the original headers:

Ok, here are my answers–sorry again for the delays in getting this to
you. Hope it was worth the wait.

I had been using Linux for a few months, and I was totally swept up by
the community atmosphere. It was really electric back then. Naturally,
one of your first reactions in a situation like that is to give back. I
wanted to contribute something. One of the most glaring shortcomings in
those days was the lack of a nicely packaged way to get Linux onto a
computer. In those days, a lot of skill and patience was required to do
that. I figured for every person that had the time and inclination to
shoehorn Linux onto a computer there would be hundreds who might find
Linux interesting if it were a bit less daunting to install it. So, I
decided to create a nicely packaged Linux system. I called it the
“Debian Linux Release” for a while, which you can see if you go back and
read the old stuff. By the way, this was before they were called
“distributions”. And it was also about a year before
Red Hat, SUSE, Caldera, and the other commercial distros started.

The reaction was extremely positive. I got a huge number of responses
to that first post. I still have hardcopy that I printed on a Citoh
printer the size of a Volkswagen in the basement of the Math building at
Purdue. One of those early responses was from Richard Stallman, who
said, “We’re starting to get interested in Linux and are thinking of
distributing it, and we like your approach,” which absolutely stunned
me–one minute, I’m this random guy, the next minute I’m trading email
with Richard Stallman. It was almost surreal. It’s a good thing
I printed it all off, because when you’re developing operating systems,
and you can’t afford a separate test system, you tend to lose your data
from time to time, and I did that several times over. So a
lot of that early correspondence is gone now, except for what I printed.

Here’s a bit of history I’ve never talked about before in an interview:
In August 1994 or so, we got an email from Marc Ewing, who said, “I’m a
big Debian fan, and I’m starting a company called Red Hat to make a
commercial Linux product, and I’d like to base it on Debian, not really a
company yet, just me…” Of course, it didn’t happen that way, but
wouldn’t that have been interesting? (Especially for my bank account.)
Pat Volkerding and I also toyed around with the idea of merging
Debian and Slackware too, but that never happened, mostly because
Pat thought the distributed development model would never work.

Yes, I’m 33. I loved my time at Purdue. It was still in that magical
time when computers (or powerful ones anyway) weren’t available to
just anybody. As an undergraduate, the only system we had access to
was a Sequent Symmetry running Dynix, Sequent’s long dead Unix
variant. There were a variety of terminal rooms around campus that
we could use to connect to it, mostly on old Z29s. I spent a lot of
time in those labs with friends of mine, Jason Balicki and Mike
Dickey, learning every nook and cranny of Unix. We used to prowl
around campus looking for labs with laser printers or X terminals.
We used to drool over the Sun workstations. We used to go to the
Math building and stare at the Sequents through plate glass, enviously
watching the lucky bastards who got to log in at the system console as
root. Deb was my girlfriend at the time, and is now my wife. We’ve
been married for almost 12 years and have three beautiful children.
Deb’s a wonderful woman and has always tolerated me and the fact
that I’ve always got a project of some sort that’s preoccupying me.

It wasn’t that hard. Even back then, the community was large, and there
was always someone willing to help out. The Debian mailing lists were run
from Bruce’s workstation at Pixar. Pixar as a company certainly wasn’t
supporting Debian, though they had to know about the mailing
lists (they were widely publicized) and never did anything about them.

The growth has been in fits and starts. The project hovered around
200 developers for a long time in the mid-1990s. There was talk that
Debian had hit a ceiling, that it couldn’t grow any more. Of course,
that proved to be false. Debian’s gone through growing pains, just like
it’s going through growing pains now with the release process. It’ll
get through, just like it always has. Some people forget that it’s
hard to run a large organization, and that’s essentially what Debian
is. A 1,200 person organization is large for a *company*, and things
get even harder when you’re not writing paychecks to motivate people.

Statistically, getting a project off the ground is the hard part. Most
new endeavors never get beyond the initial idea. With Debian, I was
lucky–I was in the right place at the right time with the right ideas.
I learned with later projects, like Progeny, how hard it truly is to get
something to catch fire like that. For Debian, the hardest part by far
was the growth and managing it. How do you go from one person to 60
people and not fly apart at the seams doing so? It’s hard enough to do
that in a company, but we were doing something absolutely
unprecedented. Distributed development may be commonplace now, but
it certainly wasn’t commonplace back then. The conventional
wisdom was that it wouldn’t work, and that Linux was an aberration.

I’m happy to say that that’s changing, and that Etch will be fully
compliant and certified when it’s released later this year.

So, I guess I’m seen as something of an Ubuntu opponent, but that’s not
true. In one sense, there was some “vendor sports” going on there, as
Doc Searls would say, because Progeny and Canonical were competitors. But
the big part of it was genuine concern about compatibility. The idea of
.deb packages that wouldn’t install on Debian really worried me. I
remember seeing the first RPMs in the early 1990s that wouldn’t work on
Red Hat, and we all know where that went. Fortunately, the problem has
been averted–Canonical and Ubuntu are fully committed to the LSB, which
by definition will preserve compatibility not just between Ubuntu and
Debian, but between Ubuntu and all the other distros as well. So, all
of my concerns, and everything that led to the DCC, have been addressed
(which, by the way, is why you don’t hear much from the DCC anymore).

Debian is everywhere, and there is enormous interest in it in the
“enterprise”, I can attest to that. The problems aren’t with the
technology, they have more to do with the fact that most enterprises
aren’t quite sure what to make of a community project without support
guarantees and such. My key bits of advice would be to adopt a
predictable 18-24 month release cycle (we seem to be well on our way
there now with etch); to support the LSB, so that Debian gets into
the same cadence as the enterprise distros and so that ISVs have some
way of targeting the Debian platform without having to deviate from
their other ports too much (again, we’re in good shape here on the
present course); to commit to long term support (Red Hat and Novell are
both providing seven years of support now, which Debian can and should do
in the form of backporting security updates and critical bug fixes); and
to generally be responsive to the needs of commercial users (I’ve often
run into people who have contacted Debian, only to be met with
a deafening silence or a “we don’t care about commercial guff” response).

The LSB doesn’t prefer RPM, though that’s a common misconception. We’re
planning to add alien to the LSB SDK, so ISVs can easily make .debs of
their LSB RPMs, as well as scripts to easily generate APT repositories
containing those converted .debs. The bottom line is that we want to make
it easy to install LSB applications using the distro’s “best
practice” method, and on Debian, that means APT. Furthermore, in LSB 4.0,
we’ll be revisiting the entire packaging question. We’re holding a
Packaging Summit in Berlin later this year to get the discussion started.

In many ways, Debian captures the essence of what Linux was in 1993. It’s
that essence that makes it special. It’s where we all came from. I’m a
big believer in the importance of commercialization (that’s how you have
maximum impact on the world), but I’m also a big believer in never
forgetting where you came from. If that gets left behind, then Linux just
becomes yet another Unix clone, and what’s interesting about that?

> C2. The future of that ecosystem, and of FOSS in general?

Looks bright to me, as long as we proceed on the present course.
To my previous point, the big commercial players understand that
Linux is different, and understand the importance of community. They
don’t want a repeat of UNIX. My one concern about the community is that
it’s sometimes fixated on the wrong things–software licensing, for one,
is less and less relevant today, as Tim O’Reilly has pointed out for
years. The future of software is on the web, not in tarballs. The
interesting software isn’t “distributed” anymore. There’s a real risk
that the community will get left behind unless it updates its thinking in
some of those key areas. And the mob mentality of the community is a real
concern too. Progress often means going against the conventional wisdom,
and it takes a steely kind of person to go against the grain in this
community, given how easy it is to tear people down by email at a
distance and at massive scale. I often wonder how much more we could
accomplish if there were lower barriers to sticking your neck out.

> C3. Debian on everything from small embedded to 512-way SMB systems?

Debian’s a great fit here because it’s so easy to customize to these
vastly different configurations. And it’s also easy for the vendors of
those hardware systems to support it. You don’t have to wait for some
third party OS vendor to decide your platform is at an interesting enough
scale to support it. And you don’t have to do all that work yourself.

I hear a lot of people say that computer science isn’t an interesting
area anymore, but I thoroughly disagree with that. There’s still an
enormous number of problems to be solved. I’m not sure how many of
those problems are in the operating system anymore, at least the operating
system in the traditional sense, but the web in particular is still in its
infancy in terms of what can be done with it. Of course, there are plenty
of interesting problems in other disciplines, particularly around energy,
but I’m a computer guy. What I’ll tell my kids is to find something you
love to do. That way, it isn’t work, and you get paid to play all day.
What I tell open source developers is to think big, audacious thoughts.
Particularly if you’re young, not married, don’t have kids, etc.,
you have nothing to lose–enjoy it while it lasts, because it doesn’t..

Sure, though my turnaround time may be slow.

##### Original email from Ian Murdock ends here #####

Thanks again Ian. It was an honour and a pleasure to meet you, and I’m still using Debian both at home (where I write this) and on my server (from which people can read this).

To all our readers, as always, thanks for reading.

Impressions from bowling

Today (Tuesday) Zuleikha invited some of her friends to her birthday party. She wanted to go bowling again, so this is what the kids did. I took some photos, most of which I cannot show without getting allowance for that first, so here are only two:


Impressionen vom Bowling


Impressionen vom Bowling

As you can probably see, the hosts dimmed the lights and switched on disco lights, and the kids were absolutely delighted about that, but for photography that was of course a challenge. I used the brightest lens I had (Panasonic Leica DG Summilux 25mm/1.4) wide open and the camera at ISO 1600, and still I’ve got a lot of movement blur. But that often adds to the vibe, because the kids were moving simultaneously and most of their time, so in lots of photos I have exactly one detail (face, hand, ball etc.) sharp.

Just uploaded a few of them into my dropbox for the other parents, and of course for the kids as well.

We all think we’ve had a great time, and hopefully all of Zuleikha’s guests enjoyed it also. Should anyone of you read this, then thanks again for coming; it was a pleasure to have you around.

Thanks for reading.

Pictures from paradise

My colleague Arno and his wife are on Ko Samui, and our colleague Nabil is on Phuket. Some ten days ago, Arno sent a picture which he took with his phone, writing that he doesn’t really want to come back…

Reminded me of our last time in Malaysia, which is five years ago already. Well, paradise, yes, maybe. For us. But first and foremost, it’s hot. You’re sweating without doing much:


Zuleikha, Malaysia 2010

So after noon, you sometimes just sit around, feeding keropok to the cats:


The kids – here are some of our relatives – play and pose, but even under the trees in some other kampung further North, it’s hot – and at night, you’ll get eaten up by mosquitoes:



Finally, here are two portraits I made during that holiday (I’ve shown them before). The first one is of Comel who is now married and has a baby boy herself:


Comel, July 2010

And the second one is of her brother, who sadly isn’t amongst us anymore:


Mohammed Haniff, July 2010

So is Malaysia, or is Thailand paradise? Like I wrote above: Well, paradise, yes, maybe. For us. But that is only because first these people – relatives or not – will do everything they can to make it paradise for you, and second we’re ignoring most of their problems.

Have to go back there soon…

A “featured” image

Never tried this until now, so I decided to have a look at blog posts with a “featured” image.

The one you see here is one of myself, but it is not a “selfie”. It was taken by Mélanie Gomez in February, two days before my birthday. She used her Nikon D800 camera and one of my studio strobes (and grey background) to make this.

Merçi encore, chère Mélanie!

Of course I had to take some of her as well. Here’s one I took using my E-PL5 with the 45mm lens, also with studio strobes:


Mélanie Gomez, February 2015

Thanks for viewing. is 15. Or was it 16?

Today I was working on our server a bit, updating and checking things, and everything runs smoothly. I was wondering about the past a bit while I did all this, and so I checked.

Netcraft first “saw” us in the year 2000, which means that I used Netcraft’s services to check on us. The Internet Archive, and its Wayback Machine still have some stuff starting from 2001, and our site looked like this, or like that. I also had my own hosting company during 2001, called “”, but nothing much of it is left, and that was later taken by domain grabbers. From 2005 Netcraft’s site saw us hosted by other companies.

So while the oldest history might be from early 2000, I think I actually registered the domain in 1999 – would have to check with Denic to find out. And, as I wrote on one of these early pages, the internet as we know it now was barely 10 years old (that means the mouse-clickable web, some other stuff like internet news is older).

Fifteen years only, and even less since people started to stare at small screens while walking the cities. Feels much longer tho – but imagine how life was before that (hint: it wasn’t worse).

Thanks for reading.

Pictures from an exhibition

Well – the title is slightly misleading. Firstly, yesterday’s event was way more than just an exhibition, and it also has nothing to do with Emerson, Lake & Palmer (or Mussorgsky for that matter, and that is why I didn’t call it pictures *of* an exhibition). So here are a few photos from “Home is where…”:




Huge prints


Huge camera

And while speaking the keynote (or the laudatio), Markus took my picture as well, and he kindly allowed me to show it here:
