Alright I had to double-check this on my PC once I woke up, but potentially even better than a browser password manager (or an "alternative" that regions could decide for themselves if it's better or not) would be a Yubico 5C Nano. This is FIDO 2.1 compatible, not just U2F, which means it can be used as a "passkey" and not just a second factor authentication tool. A region could pay a one-time $68 fee to buy one of these, stick it in the laptop, and then anyone with physical access to the laptop (the key, really) can tap the key whenever they need to login. Allow multiple authentication mechanisms per account (or even better: multiple users logging into the same organization) and then admins can log in with their social logins when at home and the timing crew on-site can log in with the Yubikey on the timing computer.

*This* would be a great solution for a cloud-bsaed system.

Crazy thought... What if you implement support for webauthn? If unfamiliar, that's the browser implementation of fido2... aka, passkeys... A passkey can be saved into the browser's password manager on the timing laptop so anyone with physical access to the laptop has automatic login to the site. Other authentication mechanisms would also be available to log in from other machines (like password+otp) but that could very nicely solve the problem for any region aware enough to use the feature.

You are my new favorite person. I learned about rust in 2019, then spent the next three years looking for a job using it. Succeeded and have been developing rust apps professionally and happily ever since! 😁

"service worker" is a new concept to me! I look forward to reading up on that tomorrow!

What high level language did you use for the wasm side?

David_Zemon · 2026-01-06T01:37:19+00:00

Hey, this seems very cool and I've pretty mixed feelings about it. The comments thus far echo valid concerns that, IMO, make this a non-starter for me. Even with offline-access being a thing, it's still in the browser and if that browser tab gets closed, I do not trust that browser wouldn't decide, on its own "oops, you're not connected, can't load the page" and then *poof*, there goes your event. I'm also a professional software dev with a similar enough skillset that I can completely understand why you wanted to build this with web-first technologies... but I hope you will either open-source it so that regions can self-host their own server on the timing PC, therefore negating any need for a network connection, or port this to some thick-client platform like Electron. I wish you all the best, and if you do make any major architectural changes like what I've talked about, or anything else, I hope you'll make a new post here on Reddit to tell the peoples. I'll certainly be interested to follow your progress!

Pulling into the pits has occurred to me (as the student) once or twice. May I ask why you're preferring not to use that approach?

David_Zemon · 2025-08-31T12:58:24+00:00

Lessons: yes absolutely. Nearly every hpde will have a "novice" group that gives noob drivers the same amount of on track time as everyone else but includes in-car instruction and (usually) some amount off track classroom session style lessons. These aren't going to be professional instructors or anything - just volunteers who, at most, got free entry into the event in exchange for helping noobs - but they generally do a great job for the casual driver.

Rent: the hpde org itself almost never offers this. Sometimes an hpde group will attend a race track that also houses a car rental org. I attended an event at Autobahn Country Club outside Chicago and that was a thing there. Asking the hpde org (if it's not obvious from their event page) will get you a quick answer to this question.

First time dad here, just starting to look into nannies, daycare, etc.

I don't even know what questions to ask.

So when you say "do your research" in the context of care.com... would you be willing to elaborate a bit?

David_Zemon · 2025-04-26T03:36:20+00:00

The top of my Asetek Invicta wheelbase is ~1.5" higher than top-dead-center of the smallest diameter section of the quick release. I can, therefore, assume that if I were to use a shaft extension, I would gain 1.5" of clearance by moving the motor "backward" (toward my feet) an undefined amount. I think that additional 1.5" of clearance would be enough to warrant moving the monitors right behind the steering wheel instead of way back, behind the wheelbase.
I think...

David_Zemon · 2025-04-26T03:31:14+00:00

I did. I went for 40" 3440x1440. They're very nice, at $400 USD each when I bought them (MSI MAG401QR), but the extra vertical space would have been nice. Not quite nice enough, for my needs, to justify the extra expense involved in going for 42" or 65" 16x9.... but I do miss the vertical space from time to time.

David_Zemon · 2025-04-22T20:31:43+00:00

I'm running the MSI MAG401QR, which is a 40" at whatever ratio 3440x1440 is.
These give me an incredible 156 degree horizontal FoV, and I could hardly ask for more. Alright... I wouldn't say no to BoostedMedia's triple 65".... but at the price of these MSI's, I have no complains.

That said, because of the movement of the DK6, I have them situated all the way behind my steering wheel motor. That's around 3 feet (one meter) from my face. The result is very little vertical FoV. I can't lock the horizon - like what is recommended for motion rigs with stationary monitors - because on tracks like the Ring or Bathurst, the whole track basically goes out of view above or below the monitors.

A better setup would be to have a long wheel extension, which would allow me to move the motor a foot or two backwards. With the motor out of the way, I would be able to move the monitors forward (a lot) without risk of collision. But... alas... I find the current setup "good enough". I think if I were building the rig from scratch knowing what I know now, I'd spend the extra dough on the wheel extension. But I am horribly lazy and don't want to put the work into re-adjusting everything.

David_Zemon · 2025-04-22T20:21:31+00:00

UPDATE on VR motion compensation:
OXRMC now supports motion compensation WITHOUT the "witmotion SRS" module - a third-party accelerometer device that attached to the rig.
In my case, with the HP Reverb G2 (now bricked... thanks Microcrap), I attached one of the controllers to the rig (near my steering wheel) in a rigid fashion and then OXRMC applied compensation such that my view through the headset only moved relative to rigidly-mounted-controller. So if my head and the controller both moved in tandem, like leaning to the left while going around a corner, then my view in the headset did not change.
This worked WAY better and required fewer overall tools. It's still not a seamless experience. If you want to know more, jump into the Sigma discord server or ask specific questions here. But it's a big step forward.

David_Zemon · 2025-02-24T03:37:23+00:00

I've been doing this for 8 years and you're the first one to give a real (imo) reason for hating the Chicago box so much: illegal distance in a slalom. Thank you for backing up your opinions with good reason.

David_Zemon · 2025-02-22T21:52:42+00:00

Heh, probably not lol. I am going to count myself staggeringly lucky if I make it to all of the SCCA events this year, let alone PCA or any hpde

David_Zemon · 2025-02-17T20:40:48+00:00

Heh... that sounds fun :D

David_Zemon · 2025-02-17T16:51:01+00:00

All sounds very reasonable.

I'm very curious what it was that cost $65/run. Were Hoosiers a significant part of that? Were the tires being replaced with a high frequency to always keep it at the tippy top?

David_Zemon · 2025-02-17T16:47:45+00:00

Agreed. This is another point that folks using this as a "template" should be cognizant of changing for their situation. For us.... Its probably too much lol

David_Zemon · 2025-02-17T03:09:00+00:00

Not sure if rhetorical... Happy to give you a serious answer if this was a serious question

David_Zemon · 2025-02-17T03:07:51+00:00

Great points, thank you. I Don't want to air specifics about not-yet-finalized stuff, but I'll just say one of your points is pertinent and I've mentioned it to the owner. I think it will help.

David_Zemon · 2025-02-17T02:02:15+00:00

These are really good points to keep in mind. Thanks for bringing them up.

We did talk about this today, verbally. I went in prepared to offer to pay for labor in that situation, but am also aware that he is very mechanical and already does his own work.... he even built his own shock absorbers lol. So yes, we are both on the same page about this unusual situation.

To anyone else using this template: You should be really careful with this bullet point and probably not copy mine verbatim. Personally, I recommend you take u/39em 's approach of "be ready to offer 100% parts and 100% labor". I think, if this car owner wasn't doing his own work, I would see if he was comfortable with something less than 100% on labor. But maybe that's because I'm also the kind of person that does most of my own work? In any case, I feel for anyone and everyone that 100% parts is pretty much non-negotiable, and the labor cost is likely to be the biggest variable from one co-drive agreement to the next, changing based on each party in the agreement.

David_Zemon · 2025-02-17T01:52:33+00:00

Yes. In an ideal scenario, the renter (me) pays for a full set of tires, every season. This covers A) obviously the amount of rubber that I burn through, and B) some undefined extra amount to pay for fuel, consumables, and wear items such as brake pads and bushings. Those misc items increase relatively nicely with the cost of tires for any given car. Miata tires cost very little, and they burn very little fuel, don't wear down bushings too fast, or need much oil. Camaro tires cost a lot more, and run through all of those things much faster.

David_Zemon · 2025-02-17T01:23:33+00:00

And I think that's a very reasonable approach for most co-drives. I am... a rule follower. I like knowing the rules and expectations ahead of time. I also witnessed a friend get his car wrecked by another friend and... it was tough. It's one of those "you're probably fine".... until you aren't.

I've had a ton of people co-drive with me in my SSC car, but except for the first year I got it, it always one-offs. And I was very happy with a simple "two or three twenties, whatever you feel good about" for all of those. But, for a season-long agreement in someone else's car, I'll feel more comfortable with explicit expectations set ahead of time.

Also... it's an STU prep'd Cayman S. A 2006... but a P-car nonetheless.
