Steorn
The Steorn thing mentioned in my previous post appears to be going strong, quite a number of people have been investigating the company and their claims. Given the statements made by Steorn, things discovered about their past, the nature of their actions, three possible situations remain possible:
- They have found something real
- They are really really crooked and onto their last straw, and haven’t thought it through
- They are deluding themselves
Situation 1 would be cool. Situation 2 requires them not to be thinking straight - it appears they are not going to be accepting or even seeking any money unless their technology is vindicated. Situation 3 has happened in the past. It might be that some of their engineers are faking measurements, and have convinced the rest of the company.
I’m afraid it might be 3, but 1 is still a real possibility. There has been some speculation on forums that the physics of permanent magnets isn’t as solid as you might think.
A nice quote by Tatiana Makarova of Umea University, who has discovered the first carbon magnets:
“Only a few people understand or think they understand how a permanent magnet works,” says Makarova. “The magnet of everyday life is not a simple thing. It’s a quantum-mechanics thing.”
So it is not that outlandish that something might be hiding in there. I’ve tried to follow carbon magnet research a bit, it appears that as of 2006 it has been confirmed abundantly, but not explained. More detail here.
All very interesting. One sad possibility is that the Steorn device might only be cooling the air around it a bit, because of thermodynamic effects of magnetic domain randomisation/ordering.
It appears the Steorn people are aware of this possibility though, given how they stress a full thermodynamic evaluation will be needed.

Regular readers of this blog may know I have an interest in new physics, or
as some of my learned friends call it, fringe physics, the latter not being
a positive connotation.
This week a company called Steorn took out a full page advertisement in the
Economist, a respected newspaper, announcing their invention of a ‘free
energy’ device. Part of the exact text of the ad reads:
“Imagine - A world with an infinite supply of pure energy. Never having to
recharge your phone. Never having to refuel your car”.
To validate their bold claims, they are seeking twelve “most qualified and
most cynical” scientists. We are told a number of physicists have already
investigated their device, but are unwilling to go on the record with their
endorsement.
Now, does all of this make sense? Is it a setup, or a scam, or a bunch of
delusioned people?
(Update: ok, I have a theory based on research reported on the Wikipedia. It appears the company Steorn is somewhat defunct, and may have in fact been empty. One thing that might have happened is that someone took over this empty shell, and is using it to launch a kind of ’Space Cadets’ TV show. This is exacerbated by the fact the the advertising agency that does the Steorn promotion is also used by ITV. See this article).
The media has already sought and found a number of scientists willing to say
it can’t possibly be true, with choice quotes like “Irish energy miracle ‘a
joke’”.
State of Physics
This article isn’t really about the possible veracity of their claims, but I
do want to say a few things about the state of physics.
Arthur C. Clarke said in 1962:
“When a distinguished but elderly scientist states that something is
possible, he is almost certainly right. When he states that something
is impossible, he is very probably wrong.”
Over the years this dictum has changed, and we can safely remove the word
‘elderly’ from the above. For the past half century, physics has mostly been
about adding more decimal places to known science, while studiously ignoring
things that distract from the grandour of the fine laws of physics.
And indeed, the cries of ‘impossible’ are heard a lot, and again in the case
of Steorn. They might well be correct. But physics is no longer the secure
place it once was. Breaking the speed of light is also impossible, but when
that same speed became an impediment to the ‘big bang’ model of physics, it
was quickly decided that, well, if we’d have to otherwise rewrite all our
laws, then the speed of light CAN be broken.
This is called the inflationary theory of the creation of the universe, and
it is currently the most widely supported explanation of the big bang. From
the Wikipedia entry on the ’Inflationary Epoch’:
“Most scientists estimate the duration of the inflationary epoch as 10^-32 of
a second. During this time, the size of the universe increased by a factor
of 10^50 from an initial size of 10^-26 meters in diameter (a hundred billion
times smaller than a proton) to approximately one hundred million light
years (10^24 m) in diameter.”
This is then usually followed by a vigorous handwaving, meant to distract
the reader from the fact that we’ve just broken the very laws of physics we
are trying to save:
“This exponential inflation solves many of the problems of a simple big
bang, such as the flatness problem and the horizon problem.”
In the same way, the world of physics is currently straining to explain a
rather large number of anomalies, like what is causing the universe to
expand in the way it is. This has led to the invention of ‘dark matter’
(regular matter hidden in the universe, that we don’t see because it emits
nor reflects any light), which is not too controversial, but the sums still
didn’t work out. So ‘dark energy’ has been posited to make everything fit.
The problem is that said dark energy can’t very well exist under our current
laws, as it is supposed to exert ‘negative pressure’, acting as a sort of
negative gravity. And it has to be 70% of the mass of the universe.
Furthermore, precise and decade long measurements of space probes show they
are moving in different paths than they should be, both when passing very
quickly and closely to the earth, and when they are very far away. The
anomalies are small but highly persistent. See
Is the physics within the Solar system really understood?, and the Wikipedia entries on the flyby anomaly and on the Pioneer anomaly.
To wrap this all up, the current state of physics is not solid enough for
bold “Impossible!” statements, because impossible things are rather
regularly posited to make up the gap between reality and current laws of
physics.
Steorn’s challenge
Let’s assume they honestly believe they’ve found something. How would we go
about things? It stands to reason they want to make money from their
invention, history has been unkind to inventors hoping to get their just
rewards without also being good business people.
Also, many inventors have gone crazy and rushed out with bold claims which
later proved to be hard to validate. In the current conservative science
climate, if a third party makes a single failed attempt at replicating the
claim, you are effectively excommunicated.
The problem is that any new physics is bound to be somewhat tricky to show,
because if it weren’t, we’d have noticed the ‘new’ effects already, and they
wouldn’t be new.
The situation can be compared to making a souffle, which is notoriously
difficult to do right. Everything has to be just so, otherwise we don’t end
up with a fluffy and delightful meal, but a soggy wet mess.
Let’s say you have a physicist friend, and you describe him the joys of a
souffle, and he doesn’t believe a word of it, and requests the recipe. Still
not believing a word of it, he’ll head to his kitchen, and lo, he ends up
with a soggy wet pie.
And if this happens with your ‘new physics’ experiment, you are toast. We
all know souffles exist, and in this case, he probably did not get
everything “just right”, probably not helped by his staunch disbelief.
But in the world of physics, anybody having made a bold claim that could not
be (fully) validated instantly is shunned. Recent history is rife with
experimenters being researched for fraud, and being evicted fromt their
universities. Doing new physics is a career limiting move.
So, imagine we are Steorn, and we honestly believe we’ve hit something new,
now what. Their claim that physicists have already looked at their claims
but refuse to go on the record is highly plausible, for the reasons
described above.
However, from this we can probably also derive that their effect can’t be
stunningly obvious, as in that case they’d be able to just present people
with the aforementioned phone that never needs recharging.
Their current actions best fit the situation where they have a small effect
that they believe can be scaled up to something real with the right amount
of investment, which they might be able to attract if they can find
“respected scientists” to sign off on their current results.
I’ll be following this exciting “Willy Wonka” like event for as long as it takes, expect more posts.
In the meantime, the theory that this might all be a scam is not too plausible, Steorn has existed for a while now, the people involved appear to be real, they’d be throwing away a lot. More information is appearing on the Wikipedia Steorn entry all the time, it might be interesting to watch that too.

As previously noted, Sun is making a SunFire T2000 server available permanently for PowerDNS development, which should be good for all PowerDNS users, and probably for Sun as well. With a big PowerDNS user we are currently investigating an interaction between PowerDNS, Solaris and its Completion Ports, which may turn out not to be a PowerDNS bug. So everybody wins.
The server is arriving tomorrow at the PowerDNS offices, we hope to have it up and running shortly.
Ok, some more spiffy ‘before and after’ graphs, this time from a Solaris 10 user:
The lower graph lists the number of queries per 5 minutes. In the lowest graph, it can be seen that just before and after the maintenance period (the white bit around Mon), the number of processed queries went up substantially.
The upper graph is a plot of the load average of the server in question, which can be seen to drop visibly after this period. It is probably best to concentrate on Friday vs Wednesday. Friday, which is non-PowerDNS, did 200kqueries in 5 minutes in peak, at a load of 1.75 at peak.
The next Wednesday, we see a peak of 300kqueries in five minutes, with a load of 0.6 at peak.
If we combine these numbers, we see the efficiency (queries divided by cpu load) go up by a factor of 4. It should be noted that this is a dual CPU machine, which explains why the load can exceed 1 when running a single name server.
Thanks to Jan Gyselinck for these graphs.

(Update: I’ve upgraded my Ruby on Rails, thanks for warning me! See here)
Well, big news, we’ve decided PowerDNS needs a new homepage, and that it needs to tell you why you should run PowerDNS. All pretty obvious of course, but it took us some time to realise PowerDNS use is spreading purely based on word of mouth, and not because we promote it so well (which we don’t).
The main page currently projects a sort of post-dotbomb shareware image. The wiki is fine as it goes, but only suitable for hardcore developers. And finally, the documentation contains lots of gems on how to best use PowerDNS, but it is all very spread out.
So, until we have our new homepage, some promotion. A large PowerDNS deployment is set to make 120 servers redundant. In energy costs alone this should save around 100kW, continuously (Update: ok, perhaps a bit less. Allow me some artistic license here. If you include cooling, it is not that far off.) . For reference, that kind of power requires four of these to generate:
We might as well follow Sun’s lead and rename PowerDNS ‘The most Eco Friendly Nameserver’. EcoDNS has a nice ring to it.
Some more promotion. Switching to PowerDNS does not just save the environment, it also makes your mail go faster. A happy PowerDNS user sent us this graph:
This says, in Dutch, “average mail delivery time, in seconds”. Note the dramatic shift very early Thursday morning, from around 1.8 seconds to 0.8, and later around 0.65-ish.
The almost threefold speedup happened immediately after the switch to PowerDNS. This makes some kind of sense, with the massive amounts of spam these days, a mail server can spend an awful amount of time trying to resolve strange sender addresses, and traversing often very bad or weird reverse delegations. Spammers have also been known to try to make their DNS so misconfigured that DNS-based filtering attempts fail.
No matter what the exact cause is, there is a nearly threefold speedup. Made all the more spectacular by the non-zero based graph!
We’ll try to move the hype from here to serious white papers on the new homepage. But it feels good to share some of the improvements people are achieving by switching to PowerDNS.

Quick note. If you’ve sensed a disturbance in the force, it is because tens of millions of internet connections moved to PowerDNS just now.
I still have goosebumps.

Just got back from holiday, sadly on the same day as family member was admitted to the hospital, but that should not taint our massively succesful vacation!
For the first time, Mirjam and I were able to take our own car and drive it around Europe. Years ago our parents showed us (independently, we didn’t know each other then) the pretty places to visit in countries near and far, it is really a great feeling to be able to go out ourselves now!
Here’s a picture of our Skoda to a spectacular backdrop, and a mysterious container for ‘civil protection’:
.
Due to the heatwave in Europe, we’ve only stayed on campings above 500m, ending up at 1500m, which meant the temperatures were nice. We started at the Heidenkopf campsite in the The Elzas, which was very fine except that the sanitation is in need of modernization.
After two days there we moved to a campsite on the border between France and Switzerland. At this time, I have to explain we went on vacation with only one passport, Mirjam having lost hers a few days before we left. Most EU countries, and some non-EU ones, are members of the Schengen agreement, which means that as a rule, passports are not checked on borders. And indeed, you can pass the Dutch/Belgian border at highway speeds. There is a sign, but that’s about it.
However, given the current “security” climate, we had some fear we’d get into problems. We need not have been afraid, our 15 days of vacation passed without anybody asking for a second piece of identification. All hail the EU, in this respect.
There was some residual fear though, most European countries demand that people be able to identify themselves though. But this didn’t happen.
Ok, so we went the the ‘Haute Jura’, which stretches out over France and Switzerland. And we have a satellite navigation system.. that knows nothing about countries. It does know a good road when it sees one though, and the ones in Switzerland in that area are superiour to those in France. So given any chance, the navigation computer sends you to Switzerland, even when your final destination is in France. Switzerland, while a member of the Schengen agreement, does have serious border control. Furthermore, Swiss highways are very expensive to drive on, requiring a certificate.
I think we’ve seen half a dozen Swiss border posts while in the Haute Jura, they crop up everywhere! In the end we discovered the routes that stayed in France though.
After a few days there, on a rather Disneyfied campsite that had recently (it appears) been acquired by a large company with the interesting name of Homair, we left for our final destination, Courmayeur in Italy, as suggested by my father.
Courmayeur sits on the Italian side of the Mont-Blanc tunnel, and is at a height of around 1500 metres, as is the excellent La Sorgente campsite. The pictures linked to this post are from there.
We spent 6 days excellent there, and then drove back, staying the night in a very fine St. Martin (Logis the France) hotel, in a village of 280 people. It did serve a four course dinner with excellent wine and cheese though.
On driving back, Mirjam and I remarked that it got awfully hot in the car. When we stopped for one of our frequent breaks, we saw a newspaper with ‘39C in the shade’ filling most of the front page (around 102F) - we thought it was just us having a hot car.
Camping
People either love or hate it. I think a fair amount of emotion is involved - when you mention you had a great time camping, you often encounter people gushing to share horror stories with you how everything went wrong when they tried it. The passion with which these feelings are shared is stunning, it must hit something deep.
I’ve long learned not to try to convince these people, but it hurts me to know what they are missing!
First, a picture to show what I mean:
Our tent is the small one hiding under the tree. Imagine waking up to that sight. Pick up bread and croissants from the little shop, make some coffee, bake an egg, and just let the scenery work on you.
There is a sort of magic on these campsites. There are lots of people, and it is nice to see them enjoying their vacation. You could talk to them, if you wanted, but you could also stick to friendly greetings, it is fine either way.
I think these other people serve as a sort of backdrop for my relaxation. For some reason, I am relaxed the minute I sit before a tent. It would be good to figure out why this is, it might help me relax during the rest of the year.
But back to the magic - it is like living in the 1950s I think. If you pick the right campsites, and this is vital, you’ll encounter a politeness rarely seen in large countries anymore. People move around carefully not to violate each other’s space, children play making joyful noises, but there is no loud music, no racket.
When people go out, they leave their tent nice and neat. Nothing obsessive about this, but in places like these it is extraordinary to not clean up before going away.
If it suddenly starts to rain, you can rest assured neighbours who remained on the campsite will notice if you’ve not closed your tent properly, and close it up for you. If a storm picks up, people will more often than not take down any parts of your tent or caravan unable to deal with the weather.
But at the same time, there is lots of privacy.
What to do
In most surveys, people tend to state that they are very active on vacation. Hiking, visiting museums, mountain climbing, diving, swimming etc are all named. Recently, there was another survey here in The Netherlands which was probably more cleverly worded, I’m not sure how they did it, but the result was that what most people enjoy doing most on holiday is… nothing (and reading).
I’ve long thought this. Hiking is fun, walking is fun, swimming is fun, the occasional museum is fun, but in the end most people, including me, just need to relax. Vacation is not work. Note that there are people who are so full of energy they can’t sit still, I hope they can relax by being active.
However, all this leaves the question, what to do for the time you are not doing any of these active things. The good news is that camping offers lots of opportunities to constructively waste time. For a start, you can spend a lot of time on cooking or otherwise preparing food. Because there is less equipment to work with, this can take as much time as you want.
In order to cook, you need to discover the local shops and/or supermarkets, which can be very exciting if you are abroad. There is bound to be stuff for sale you’ve never heard of, but which might be delicious. In Europe, for me this goes especially for France, Portugal, Spain and Italy.
Then there is the business of keeping your tent and other equipment in shape.
Before you know it, you’ve whiled away another day in serious relaxation.
Also, if you want to go do stuff, it is easy to do. In fact, due to the incredible freedom of camping, you can hop around. Want to climb several mountain ranges? By all means.
We mostly go camping with the goal to walk a lot, in practice this depends highly on what we feel like. It doesn’t really matter, you’ll rarely go bored camping.
Some tips
Ok, I can’t resist, I need to evangelise camping a bit more. I’ve heard all the horror stories from people who tried, and yes, you can mess up in a big way. Contrary to what people think, camping is not generally cheap. It can be if you know what you are doing, though.
Examples of messing up include going out with ‘stay over’ sleeping bags, which have been washed 25 times at home and are therefore severly degraded. Or borrowing a 25 year old tent from someone. Or bringing a matrass that leaks or is too thin. Or trying to erect a tent after driving a 1000km. Or picking a campsite at random and ending up with football hooligans looking for a cheap place to sleep. There are some really horrible camp sites out there.
So, here is my advice if you want to try camping:
- Find a friend who is experienced, and use him or her as a guide.
- Take extraordinary care in selecting at least the initial campsite. Preferrably ask your friend for a favorite. Invest in a good camping guide. In Europe the German ADAC ones are great. This will allow you to select a campsite that suits your needs. If you want a quiet place, select sites without disco, animation, etc. Do pick top-notch sanitation.
- You need excellent equipment. For example, modern tents are cheap, lightweight, breathe in fresh air, are extremely water tight, easy to set up, but something has to give. The dark secret is that most modern tents only last 5 or 6 long seasons. So if you decide to borrow a tent, make sure it is still in great condition. Same goes for sleeping bags, matrasses etc. This is one of the easiest ways to mess up.
- Be sure to arrive at your chosen campsite at a reasonable hour, preferrably without having exhausted yourself behind the wheel. This serves two purposes, you’ll have an easier time erecting your tent but you’ll also have a chance to find another campsite nearby if the first one disappoints, or is full.
- By all means bring a table and chairs. Also consider investing in a decent coolbox or even a refrigerator. Doing without these things seriously makes life harder. There are die-hard campers that do without all these luxuries, and I wish them good luck, but it is not for me. I like my eggs unhatched and my beer cold, and preferrably on a table!
If you have any questions, feel free to email me on bert.hubert@netherlabs.nl.
I’ll miss camping until next year…

Ok, I no longer think spammers should be shot. I now think they should be force fed their own intestines, and THEN be shot.
I’m usually a friendly kind of person, but I now estimate that I lose around 5% of my productivity on cleaning out spam from Wikis, bug trackers or mailing list queues, not even mentioning deleting unfilterable spam from my own mailbox.
The latest thing has been spammers who not just tack on advertising to the fine PowerDNS wiki, but actively delete existing content and replace it by their own advertising.
Perhaps Guantanamo does have a purpose.
Mortgage
Well, it turns out banks aren’t crazy (see previous post). If you negotiate a cut rate mortgage, they’ll start to eliminate risk left and right, because the deal is not worth it for them otherwise.
I’ve now had to provide documentation on my father, brother, all real estate agents involved, shoe sizes, and loads of other crap. Next I think they’ll ask for my swimming certificate. But they are now committed, in that they’ve provided the all important guarantee on the 10% downpayment. Which is good as it was due today :-)

PowerDNS
It’s been a period of contrasts. One the one hand I’ve had to deal with the fact that banks currently take the narrow minded view that I’m an unemployed bum (see previous post), while on the other hand the PowerDNS recursor appears to be taking the world by storm, and does bring in money.
A really really rough guestimate would be that around 40 million internet connections are now powered, or will soon be powered by PowerDNS. This includes deployments (or upcoming deployments) I know about, and a healthy 50% bonus for those people running the recursor without telling me, or having to report bugs.
The bonus is pretty conservative, I only hear from most PowerDNS users in case they have problems, and it appears many PowerDNS installations are mostly trouble free.
This also highlights a problem with generating PowerDNS, or more in general, open source, income. Being free software, we don’t make any direct money from PowerDNS sales.
Furthermore, if people really trust software, and experience nor expect any problems with it, they won’t feel the need to buy support. Nor do we really want to become a company mostly consisting of support personnel.
The upshot is that we are being punished for writing software people feel good about. Rather perverse.
The good news is that some big PowerDNS users have found it in their hearts to send money our way anyhow, either in the form of paid enhancement requests, or by simply taking out support which they don’t really expect to need.
Sun Niagara T2000
I’ve previously written about the ‘Try and Buy’ Sun ‘Coolthreads’ T2000, which was made available for us to test. More about this later, but Sun has decided to make such a server available permanently for PowerDNS development, which is good news. This is a big server with lots of processors and memory, with some special features to boot. We’ll make sure PowerDNS performs really well on this architecture, which should be good for everybody.
Mortgage
Wow, did I almost fall for it. I tend to want to understand things around me, which is why I studied physics. I’m good with numbers and I deal with complex systems all day.
Then I went to get a mortgage and decided to just trust my bank. I’ve rarely been shafted that badly. Thanks to my good friends Remco, Remco and Tsjoi, I barely escaped from a hideously complex and expensive mortgage.
It is like this (at least in The Netherlands). The bank has lots of savings from other people, and they need to make money to pay the interest those other people expect. So they decide to rent out that money to people who need it, and are willing to pay for it. A mortgage generally has a house to back it up, so their risks can be near-zero. If the mortgage is worth less than your house, perhaps because you are not an unemployed bum after all but have savings, the bank is in a happy position.
They can rent you the money for a nice fee, and if you can’t pay, they sell the house, take the money you owe them, and give you the rest. So almost no risk at all. They also demand that you insure your house, thus eliminating even the risk of it burning down.
Renting out money like this is not a high-margin product for a bank. Everybody with money to spare can offer such a deal, and competition is fierce.
So if you barge in with zero knowledge of mortgages, what happens? They sell you a monstrosity consisting of:
- an expensive life insurance (possibly including a thorough medical evaluation)
- an investment plan
- a loan you only pay interest on, and never pay back
They invest your savings for 30 years, make you pay for the life insurance, and after thirty years, in theory the life insurance pays out and your savings will have increased to an amount around the original loan, which is then paid back in one go.
Sounds fine. Except that you’ve just committed to a 30 year life insurance you could not select yourself, there is but one choice. If you die, the insurance pays the money to the bank, not to you.
Furthermore, you’ve bought a full 30 years of managed investment, so delivered by your bank. You can’t get anybody else to invest for you.
And most interestingly, in the end, if their investments didn’t work out you are screwed, because you’ll have a residual debt.
So, after my friends told me I was being screwed, I decided to get to the bottom of things. I now have a Gnumeric (Open Source equivalent of Excel) spreadsheet that is more spiffy than any of the mortgage software I’ve seen at banks, and in fact has caught a number of errors in mortgages that have been calculated for me.
Then I went back to the banks and saved a stunning 40% in total costs.
So it is really true that knowledge is power.

We bought a house! This was somewhat scary as I was in Egypt at the time, in a dreary resort (it looks nothing like this) surrounded by 60km of Red Sea and 60km of desert - and no internet. Even after fixing the network of the operator of the resort, there was no way to get online.
The following was even more scary - I don’t have a real job as such (or so the bank thinks), even though I make enough money from PowerDNS and other activities my company employs. Sadly, banks in The Netherlands still equate a normal job with income security and vice versa. So no real job, no income.
Luckily Mirjam holds a Real Job, which appears to have convinced the bank to fork over the money! The house would also not have been possible without the generosity/inheritance from my parents. House prices are crazy over here.
The ground floor of the house on the corner, it runs from just to the right of the door on the extreme left of the picture to the extreme right of the picture: 
Our upstairs neighbours walk through part of our garden.
Garden behind the house: 
Note that the realtor has a very powerful (‘lying’) lens - the garden is not as big as it appears here by far.
Same goes for the front: 
and:
.
The kitchen is the stuff of dreams:
The rest of the house is nice as well, but y’all don’t need to see my future bathroom and sleeping room :-)
Update: ok, Mirjam decided you do need to see it, read all about it here.

Ok, I’m back from Egypt. Had a stellar time, if you have a group that wants to travel to Egypt, drop me a line, the people that organized this for us are very good.
We’ve visited the pyramids, the sphinx, the egyptian museum (all in Cairo), the unfinished obelisk, Philae, the high dam (all in Aswan), Kom Ombo, Edfu (en route to Luxor), valley of the kings and Karnak (in Luxor). All very impressive.
While I was away, PowerDNS 3.1.1 has held up well, although some minor bugs are now known about. Most of these involve the new zone forwarding, and authoritative zone hosting features, which are not in wide use.
Each consecutive PowerDNS recursor release has attracted the attention of larger internet providers, but we’ve reached the end of the line now. There are none bigger than those trialling PowerDNS now. Additionally, the previous weeks have seen actual deployment to over ten million internet users.
This is a very humbling thought. The PowerDNS company and I have worked very hard at making PowerDNS the most secure, simple and capable recursor out there. In the brief time since XS4ALL funded us to add the features a modern ISP needs, the takeup has been tremendous.
It is good to be back!
