I updated Freejoin with better compatibility for newer AC versions and also some improvements and new features. On the server side race now ends correctly a set time after the first player is finished, track+car config cycle is configurable and the server has administration commands.

Get the updated version from here. The client and server are compatible with the old version as well. For running a server check the server setup guide on that page, the process is somewhat different now.

edit: I did a quick update to version 1.22, on client it fixes all servers being displayed as password protected and on server sessions are automatically added/enabled/disabled depending on cycle setting.


I had my first solo flights a week ago, phew. All went well and I have done the required 10 solo flights now for my final flight test. I was even a bit surprised how easy I felt about the first solo flight, not much anxiety at all. As such the flying itself I feel I can handle well, its any unexpected situations especially during landing that I feel anxious about.

I took some video clips and pics with the Mobius action camera I had with me on a few longer flights, they are below. Next up for me is the final flight test, then I should get my glider license and then at some point I should man up for some cross-country flying. The “standard” easy route in our club seems to be to fly from Rautavaara to Iisalmi and back which is about 100km total. Not a difficult task in good weather but you need to be prepared for an outlanding on a field and the first time doing that feels like a huge challenge.

When weather is not so good it is good time to go do some geocaching. I went to “Kaivannonkierto” trail which is on a peninsula (if thats what it is called) that you can see on the last two flying images above. It is about 3km long looping path with some 15 geocaches and water on both sides.

The nature was nice and I enjoyed the walk, though I found the idea of geocaching trails – where you place as many geocaches as you can next to some path – a bit boring. Stopping every 150m to find a cache identical to the previous one is not too exciting.

Gliding season is in full swing. I did my first flight of the summer almost a month ago already but good weathers didn’t arrive until a few weeks ago. This weekend I flew only two flights, totaling under 1 hour 30 minutes but had plenty of new experiences:

  • New personal altitude record (3000m MSL)
  • Flying inside a cloud
  • Flying in a hail storm
  • Landing during rain
  • New personal shortest flight record (under 30 seconds), because of:
  • A true, non-practice failed wind launch due to winch engine failure

Flying can be unpredictable :) Unfortunately I did not have my cameras and stuff on board so I have only some less exciting photos from the ground.

Trying cloud flying was great, I did it with a teacher of course but managed it quite well. I found trusting the instruments to be not that hard, possibly due to so much simulator flying where the instruments are the only thing you have. Resisting the temptation to react to the things you think you feel the plane is doing is challenging however.

Flight track is here, the fast rise from 1200m MSL to 3000m MSL is inside a cloud. Solo flights ahead of me next…

freejoinAnnoyed by the clumbersome booking system in recently released multiplayer for Assetto Corsa, I wanted to see if something could be done to improve it. I came up with a system that uses prebooked slots and a specially prepared client to join those slots at any time.

Experimental version for AC early access v0.9.10 is available here. It requires the client to install a modified online interface module and a server to be running a special version. See the readme there for additional information.

While it allows joining a server at any time it has some limitations. Mainly you can only select from cars that the server has prebooked and annoyingly when a race is over the session will never end until all clients have disconnected.

edit: Freejoin updated to version 1.20 with better compatibility and various fixes. See the Freejoin page for more info.

A few people have asked for cpbo to be updated to work with Arma 3 PBOs and the possibility of releasing the source. I dont have the time to work on it and its a very old project anyway so here is the source code: download.

The source is licensed under LGPL v2.1 and should compile with Visual Studio 2005.

While in the Czech Republic still a few weeks ago, I had the chance to visit Zbraslavice airfield and do some gliding way before anyone in Finland would even think of starting the gliding season. Of course the weather was not so good that day so I only did one short flight with a local teacher in the L-23 Super Blanik.

The Blanik is certainly a different beast than the modern DG-505 I had flown before. Aluminium construction, not so perfect ergonomics, no high tech gadgets to help you. But I liked it and it was an unique opportunity to have a flight logged in my logbook in another country before I even have my license :)

Short video of an aerotow start there, it was my first time experiencing that as well:

I recently got hold of the Oculus Rift DK1 but ran into a bit of a problem with the fact that my Nvidia card only has four display outputs which all were already in use. So to use the Rift I’d need to unplug one monitor, use a HDMI switch or a HDMI splitter. The splitter seemed like the best option but active splitters seemed very expensive and I read about EDID problems with passive splitters.

The EDID problem comes when you have two displays (a monitor and the Rift) at the end of the single HDMI output and Windows (or the video card) pretty much randomly uses the EDID from either one – and when it uses the one from the monitor the Oculus SDK will not detect the Rift as being attached and cannot read the information from it. A way to avoid this issue is to plug in the Rift first, let windows detect it and then plug in the monitor. But this is clumbersome and needs to be done on every reboot so it is not very practical.

Thinking about what to do about this the solution was simple: Make Windows not see the desktop monitor at all by cutting off the DDC pins from the HDMI cable that goes to the monitor. DDC is used for communicating the EDID and with those gone Windows will only be able to talk to the Rift. This of course means the Rift must be attached to have something visible in the monitor and the monitor will be limited to resolutions supported by the Rift, but in my case this is not a problem as the Rift reports it can support 1920×1200 which is the native resolution of the monitor I use.

In practice the easiest way to get rid of the DDC pins was to remove them from a HDMI to DVI adapter that goes to the monitor. In the DVI connector DDC data & clock are in pins 6 and 7:


Female side of the DVI connector. Pins number 6 and 7 are the DDC clock and data pins used for reading EDID information.

These were easy to remove with a pair of pliers, you need to be a bit careful to not bend the other pins too much but these adapters are also very cheap so its not a huge loss for it to go wrong. My result:


This is the male DVI side of a HDMI to DVI adapter with the DDC pins cut off.

I use this with a cheap passive HDMI splitter that cost 10 euros and it works well. One problem I did notice is that if I turn off the Rift box I get some signal errors visible on the monitor image, possibly the signal gets too weak when the unpowered Rift box is attached in the cable. It can be avoided by just keeping the Rift powered at all times or by unplugging the power cable from the Rift box instead of just turning it off (Reading the EDID from the Rift still works even with the box unpowered). Some shorter cables might help as well.

edit: Also I noticed that when you unplug the USB cable the rift display turns off so it is an easy way to unpower the rift when its not in use, while keeping the control box on.

Collidable objects just needed to have the string ‘wall’ in them.

I had a look at why the tree, forest, etc. collisions were not working since some Assetto Corsa patch and it turned out to be easy to fix so here is another update for Joux Plane. I improved the tree collision models as well, they no longer throw you around the track so much (rather you seem to now sometimes get stuck in them. Oh well).

Download v1.4 of Joux Plane from here.

Get version 1.41 from here.

A few of these things under the track were causing problems.

Finally got around to fix the issues in Joux Plane with the recent Assetto Corsa early access versions causing collision problems in some parts of the track. There were some leftover triangles under the track in a few places from lower LOD level mesh used originally by RBR.

A few other improvements are included also, changelog for version 1.3:

  • Removed some remnants of low detail geometry under the track causing collision issues with newer AC versions
  • Broken track section no longer adds dirt to tyres
  • All grass is now valid track to avoid penalty from small cuts
  • Added more zoomed in external cameras

Download it hereThe tree collisions also meanwhile seem to have become almost nonexistant and you can fall off the track in many places as well. But just stay on the track and you’re fine ;) Edit: Get the second updated version here instead, it fixes the collisions with trees.

Also visited Butovicke Hradiste near Prague and the National Technical Museum. Buovicke Hradiste is a hill where a fortification used to stand, nowdays nothing appears to be left of the fort except a flat hill offering a nice view to the surroundings.

On the forums Justin (born2belyin) announced that he plans to continue SoftTH development:

After a year of “kicking the tires,” I’ve decided to finally put some effort behind bringing SoftTH into the DX10/11 era. I’ll be launching a Kickstarter project within the next month or so to get some initial donations for work on SoftTH. Money donated will go toward my time as developer and toward game purchases for testing (as needed). If enough money is gained, I may even be able to pay another talented developer for his/her time on the project. I plan to work on SoftTH whether the project gets much funding/donations or not, but I will be much more likely to dedicate significant amounts of time and effort if their is a show of community support. I want to bring SoftTH forward for my own gaming purposes, and I want other gamers like myself to enjoy the benefits of SoftTH not being limited to DX8/9 games.

Visit his site at to support the project!

Finally got around adding all the old content to a new WordPress based site I have been working on for almost an year now. Never enough time for finishing anything… But now it’s done, and I might post some junk here more frequently as well.

My new year went nicely in the middle of a pitch black forest hunting some newly published geocaches, GC4W4N5 and GC4W4RX. FTF on both \o/
