Hello there. I'm this guy and this is my home page. Below are all blog posts I have written since 2007. Some of them are silly, but self-censorship would be worse I guess.
After some unfortunate bike-thieving-events half a year ago I was left with only one bike: a White road bike. It’s a good bike, I even scored a pair of carbon wheels for it.
Still, one bike is hardly enough. This year I wanted to continue the cycling season through the winter so a winter bike was needed. I also wanted a mountain bike even though I’ve spent very little time in the forest lately. But it might happen, you know?
Could these two bikes be combined? Maybe a rigid mountain bike that’s fast on the road but still survives some trails?
My last mountain bike had a suspension fork. It was nice. Trying to decide if having a rigid mountain bike was sane I came across this perfect answer on Quora:
Anyway, as you might have guessed from the picture, I found a used RCZ mountain bike for a fair price. With a belt drive instead of chain, no suspension and no gears it’s very low maintenance and perfect for winter cycling. The tires hold OK in snow and icy asphalt. How it handles in the forest remains to be seen but I try not to stress too much about it.
I did take the bike on to some trails and participated in VPCX anniversary competition (a local, not so serious cyclocross competition). The bike’s geometry was good but the gearing was really not suitable for off-road. Still a lot of fun.
Some experiences from folks who’ve switched to from Nikon to Fuji systems, something I might be doing as well. Many of these talk about Fuji’s X-T1 which is the big brother of the X-T10 I’m interested in but also about the reasons for switching.
What’s funny is that almost all of them seem to be doing the switch after owning a Nikon D800. That’s one particularly big DSLR which might play a part in why people start looking for something smaller.

When was the last time Nikon or Canon came out with a brand new camera feature on a camera that has been out more than 12 months?
I sincerely believe that by 2020 there will be hardly any new classic DSLR's being sold.
A video from Lukas Gisbert-Mora, a wedding photographer, about the reasons why he switched to Fuji X-T1. Including limitations of the Fuji.
At a wedding, actually on the dance floor, when I compared my shots taken with a Nikon and the Fuji, I could actually see that the Fuji was performing better.
When you look in the EVF (electronic viewfinder) it tells you exactly what the exposure is like, before you take the shot. You can actually be much quicker with [the Fuji] than a DSLR ... You just keep the camera to your eye and just adjust the aperture.

Despite the solid construction, the Fuji X-T1 is very light. There's a noticeable size and weight difference when I'm carrying it around, and I feel comfortable pulling it out on the street without attracting a lot of attention.
There are definitely things I'll miss about the Nikon D800: Dual card slots, snappier autofocus, higher ISO tolerance, the video capabilities.
Andy Mumford’s comparison of Nikon D800E and Fuji X-T10. Many side-by-side photos from both cameras
After spending some time playing around with the images from the XT10, I'm really impressed by the image quality and really don't feel as though I'm losing anything significant from the Nikon D800E in real world shooting conditions.
I think we’ve reached a point with image quality where improvements are more technical than real world for the work I do and I want small, light, cameras that feel almost invisible when shooting with them or carrying them around, and I want a camera that's fun to use and experiment with.
Buying a camera in 2016 is hard. What kind of camera should you buy?
Should you even buy a camera anymore? Phone cameras are beginning to be very good and they are the cameras that are literally always on you.
The iPhone 6s and Google Nexuses now have 12MP camera sensors and I’m sure other phones have even more ridiculous sensors. Phones still fall short in shooting in low light where they tend to produce noisier photos. Still, shooting with a phone hardly stops you from getting great pictures, just look at Austin Mann’s Instagram feed for example.
But let’s say you want a separate camera. For one, carrying a camera helps put you in shooting mode. Holding a camera in my hand makes me look for photo opportunities, and having the camera ready means I’m more likely to catch the photo. While phone cameras are technically good, a camera camera usually has better usability for taking pictures and adjusting the settings. And shooting with a real camera is more fun.
###DSLR vs. Mirrorless Cameras
To date, about one billion articles and blog posts have been written about “DSLR vs. mirrorless”. To summarize them all quickly:
- Mirrorless cameras are smaller and lighter to carry
- DSLRs have better grips (because of the size)
- DSLR batteries last at least twice as long (like 350 vs. 1000 shots per charge)
- DSLRs have bigger image sensors
- Optical and electronic viewfinders are different, or not
- Mirrorless are more fun
Sure there are other aspects to assess like autofocus and selection of lenses but there the gap is getting narrower. And of course people are quick to point out that not all DSLRs are big and bulky and not all mirrorless cameras are small and light. I get it, but that’s the difference in general.
Anyway, what’s interesting reading those articles is that reasons for having a DSLR are moving towards “I’m a war photographer and need the best camera there is.” And that’s a valid point. Mirrorless cameras probably aren’t replacing high-end DSLRs. For example the bigger sensor does help get marginally better pictures when there’s less light or you need to do extensive post-processing. And a DSLR is probably better if you shoot sports for a living.
But for ordinary consumers like me the mirrorless cameras are now starting to be just good enough, judging both picture quality and price. They are capable of producing high quality images in most situations without the “overhead” of carrying a DSLRs with you.
###Upgrading from Nikon D90
Most recently I’ve shot with a Nikon D90 DSLR which I bought cheap as used. It was a good camera but the image quality was not quite up to today’s standards. The camera was released in 2008 and sensor technology has advanced a bit since then. Nikon has since release three cameras in the same “prosumer” category: D7000 (2010), D7100 (2013) and D7200 (2015).
Most logical upgrade path would be to purchase the D7200 or a used D7100. Their differences are minor and both would be much better than the D90 for example in low light.
I’m not tempted to upgrade to more high-end Nikon cameras or to switch to full frame cameras (= even bigger sensors). Nikon’s prosumer line has the features I imagine needing and the D7200 at 1000€ is near the upper limit for what I would ever pay for a camera.
I’m not a professional photographer. I like taking photos but practically speaking I only take some silly photos on vacations and parties and that’s about it. There are hardly any situations where the camera would be holding me back.
###A Contender Appears
I had almost convinced myself I should buy the D7200… until a friend of a friend posted a long post on Facebook about how they love their Fuji camera and how it totally makes you like photography again. Oh boy.
That person had a Fuji X-T1 which is a bit pricey for my budget but after a frantic googling of all possible Fujifilm cameras I found two other models that had very favorable reviews: the X-E2 and the X-T10. The latter is a slightly stripped down version of the X-T1 (no weather-sealing, smaller buffer) but it’s also more affordable: with a 18-55mm kit lens it costs just a bit more than the D7200.
One key feature that makes Fujis fun is repeated in several reviews: dials on top of the camera. The X-T10 has dials for exposure compensation, shutter speed and drive mode. This may not seem like a big deal, but on Nikon digital cameras those specific functions are handled with two anonymous front and back dials. What’s worse, they seem to be weirdly modal: sometimes spinning the real dial doesn’t change exposure or the front dial won’t change the shutter speed. Dedicating dials with numbers on them for these functions sounds promising.
The top dials also remind me of my first serious camera, the Nikon FA that I inherited from my father. It has dials for ISO, exposure compensation, shutter speed and shooting mode:
That’s one camera I’d like to use if shooting film wasn’t such a hassle.
One downside of Fuji is that their lenses are a bit expensive. There are no 200€ FUJINON lenses similar to the Nikkor 35mm/1.8 (which offers great bang for the buck). All Fuji lenses start at 450€ and quickly climb to 1000€ range, for example for the 23mm/1.4.
However, there are some cheap adapters and some expensive adapters, like Metabones Speed Booster ULTRA which would let me use my current Nikkor lenses on the Fuji. The Metabones adapter is interesting as it has a focal length ratio of 0.71 which combined with the camera’s 1.5x ratio makes an effective 1.07 multiplier. So a 35mm lens with the adapter would act as a 37mm lens. It also increases the maximum aperture by 1 stop.
I found some interesting stories from people switching to Fuji including people who used to own Nikons. I could link to some of them in another post. I haven’t made the jump yet so I’m still speculating while I’m saving the money. But at least the options are now interesting and seem fun!
Call of Duty: Black Ops II is a 2012 first-person shooter game for the previous generation consoles (PS3, Xbox 360, Wii U). While the game is a bit old, its multiplayer mode is still insanely popular.
Most of the multiplayer action happens in Team Deathmatch which is a fast-paced, two team run-shoot-die game mode.
And I have been playing that a lot lately (under my secret alias Oivaraattori).
###Picking a map
A key part of the team deathmatch is voting for the next map to be played. In Black Ops II there are 15 standard maps to choose from.
Each player can either vote a new map chosen randomly by the game, the previous map, or a random map which is revealed when voting ends.
If a map has been played two times in a row it cannot be voted again and only available options are the new map suggested by the game or a random map.
After playing a while you start to see which of the 15 maps usually win the vote. Players seem to be surprisingly unanimous about the ranking of the maps.
I decided to find out if certain maps really are more likely to win, and which of the maps are most popular.
I collected data by observing map voting until the maps had completed a double round-robin tournament: each map faced all other maps twice in a vote.
In practice I didn’t get 100% coverage of all the possible map pairs. Some maps just don’t come up often enough in voting and waiting for those pairs to play out would have taken a very long time.
In the end I observed 193 map pairs out of the 256 possible (75% coverage). This gave enough data to see which maps tend to win, but certain groups of maps might have had different order with more data.
Map Winning percentage Nuketown 100% Hijacked 82.1% Standoff 77.8% Raid 75% Random 66.7% Express 46.2% Yemen 40% Carrier 28% Turbine 22.7% Meltdown 22.2% Plaza 19% Slums 18.2% Drone 15% Overflow 15% Cargo 5.3% Aftermath 0%
So, there you have it. Nuketown 2025 was the clear winner. The map never loses a vote. On the other end of the spectrum Aftermath was a clear loser, never winning a vote against any of the other maps.
The random line is interesting. If given an option below the random line people are more likely to vote for random in order to possibly get one of the four “good” maps above it. The maps above the line nearly always beat random in a vote. If players were given a free choice they would probably just play the top-4 maps.
As mentioned before, some maps were really close and could easily have changed order given slightly different votes or more data. Carrier / Turbine / Meltdown were always close, as were Plaza / Slums / Drone / Overflow. Of the top maps Hijacked, Standoff, and Raid were almost equally as good.
Personally I feel the results are OK. Nuketown is a really fun map with many ways to play it and limited sniper action. And I dislike Drone because it’s mostly a sniper map with some anemic close combat action but apparently it has some fans.
I’m sure Treyarch would have a lot more data about this but I haven’t come across any official rankings. If some previous work exists or you have better data hit me up on Twitter!
During a recent road trip to Croatia we booked most of our accommodation through Airbnb. We hadn’t booked anything in advance and at the height of the summer season there were no cheap hotels left. Airbnb had much more choice and prices were reasonable if not cheap.
This was my first time of really using Airbnb and I was surprised to find out that all the apartments and rooms we booked were run by professional accommodation businesses. One was actually a hostel but really felt more like a hotel minus the breakfast.
I had an obviously erroneous image of Airbnb selection consisting of people renting out their flats but it seems these companies just use Airbnb as an additional sales channel. The same apartments could have been booked for example through booking.com.
Not that there’s anything wrong with that. It was just a bit surprising considering the image I had of Airbnb. It’s understandable that touristy cities have lots of apartments to rent and they are sold through any channel possible.
One downside of this is that many of the places we looked didn’t have reviews on Airbnb but they might have had on other booking sites. Airbnb also hides the exact location of the apartments prior to booking them which seems a bit unnecessary given they are not anyone’s homes. Anyway, one lesson learned again.
