    Perhaps this is why I particularly didn’t find the locomotive physics that strange

    The reason why you didn’t think it strange is because you don’t know how one works, because there’s multiple things which don’t make sense otherwise.

    The drive wheels are not the ones at the back but the ones with the connecting rods and piston rods (the pistons provide the drive force). The rods are placed in a way which would prevent the wheels turning if connected in those positions and would typically be placed on the largest wheels of the locomotive (i.e. that big wheel should be the drive wheel if it’s going to be there).

    The smoke should be coming from the very front of the locomotive as the output from the firebox needs to run through the boiler (most of the front of the machine) in order to generate the steam needed to actually drive the locomotive. Having it come from the back makes no sense unless the whole boiler arrangement is also reversed and it isn’t.


  • I paid $12 (USD) for a .in and $32 for a .nu with Namecheap, $20 (AUD) for a .au and $59 for a .email with VentraIP.

    I can’t really recommend Namecheap though because you can’t count on getting support if you need it. A couple of years back I needed to change my account email with them due to Google being an arse and locking me out of my primary gmail account (namecheap required an email code to log in to the domain dashboard but I couldn’t view the email), put a support ticket in while logged into the same account in their support portal and they ignored me for close on a month. At that point I managed to get back into the gmail account so didn’t need their help anymore, I sent Namecheap back a message saying I was unhappy with their lack of help. About six months later they sent their one and only reply to my ticket, basically saying they were sorry I was unhappy but they didn’t see a problem with the time they took.

    I must admit I still have domains with Namecheap because sometimes it’s just hard to get around to changing things, but I was reminded of their lack of competence literally this morning. They sent me an email saying I needed to update my domain contact info so I logged in and went to change it only to find their contact update form is broken and won’t submit…

    VentraIP hasn’t given me any issues so far with either their domain or email hosting but I haven’t had to rely on their support so I can’t say how good they are with that.





  • Between photography, motorcycles, and tools (woodworking/metalworking/automotive) this does seem accurate for me - I have ended up spending a fair chunk of money between these over the years. The tools do mean I can do stuff myself though rather than paying someone else so they at least are less of a money pit.

    Every now and then I think paragliding would be an interesting thing to try but I have to tell myself another expensive hobby is hard to justify when I’d like to actually own a place to live some day.

    The primary factor is that 120mm is not the actual focal length of the lens in the phone, that will be a considerably smaller focal length that happens to give the same field of view as a 120mm lens on a full frame camera (i.e. the same sensor size as a 35mm film frame). The phone uses a much smaller sensor than this hence the smaller focal length for the same FoV.

    Another thing that helps is using a telephoto lens design - including this lets you create a lens noticeably shorter than its focal length.

    When the lens would still make an overly wide phone despite all this that’s where the periscope lens design as others have already mentioned comes in.



  • I could see the benefits of using Arch just so almost every function my system has is near-perfectly documented in Arch Wiki.

    That is literally the main reason I started using it - over time I kept running across helpful Arch wiki articles while looking for info on stuff so when I got a new computer I figured I might as well go with Arch.





  • I had an old Series era Landrover as a paddock basher when I was a kid, that had a manual choke. It also had a backup crank handle for starting the engine which I had to use occasionally as I was using starter batteries which had been retired from usage in the family cars, a gearbox with no synchro on first/second, and the foot brake didn’t work. Would recommend, I definitely had fun.
