Practice, Product, and Progress

I’ve been spending time in iRacing learning the line, got both of David Murry’s excellent Sebring, and Car Suspension webinars, as well as reviewing playbacks from the VRS datapacks. I really look forward to working with David directly on the Test/Tune day before the weekend at Sebring. I was also able to spend some very productive time this week out at Harris Hill with Andris of Gradient Racing. More seat time, and getting everybody familiar with the car is always a good thing

Over the holiday, I got a lot of work done on the trackNotes app, it is nearly ready for an alpha release. I am using creator, for the front-end, and firebase for the backend. I put together some wireframes for another app I am developing called setupBoard, that will work either standalone or together with trackNotes. Regarding my work with Kubeflow, it has gone very well, I was able to train against my dataset with multiple models, distributed across three cloud providers: GCP, AWS, and IBM. Inception v3 is the current leader with predictions of 85% accuracy against the ground truth in testing. I am going to test a couple more models: Random Forest, a TF Boosted Tree, and a DNN Classifier. Once I have another round of training, and testing I will start working through AI assisted hyper-parameter tuning to see if I can get the error rate any better. At that point I will switch gears and start working on the front-end.

On the health front, I was having a hard time finding someone who could help me with both my nutrition, and training. I was referred to Phil Gephart who immediately exceeded my expectations for his knowledge, and professionalism. Phil is awesome! He worked with me to switch around my macros, added some supplements, changed up my training program, I am already seeing some incredible results with a 3% drop in body fat within the first week!

Over the Holidays

I have always loved this time of year, it has given me a chance to focus on the things that I really want to do, interesting projects, time to catch up with friends, and family, play games (or get in some iRacing time, got to get Sebring down), watch movies, and just relax. I am off from work for the next couple weeks, and will be focused on a quite a few things, as usual.

I have built, and deployed three kubernetes clusters on the three different cloud providers that came with my having joined FFL (GCP, AWS, and IBM), I have tested all of my training jobs, and am now ready to do a big run on distributed training using kubeflow, I will be working on a couple different models, Inception v3 to start, and will be working through all the hyperparameter tuning involved with trying to get the best RMSE for what I am doing, hint (it’s motorsports related).

Also, I have a prototype of the trackNotes app, that I released to the Play Store for a closed Alpha, to get some feedback on the UI, I am putting it together with creator.  I am working on the backend data-model in Firebase, which is pretty straightforward, there are some really good materials out there, I really like the codelab, it is ridiculously comprehensive. I am also going to start a wireframe for another app called setupBoard.

On the racing front, I am doing outreach for sponsors, and will need to get all of that loaded into Hubspot so I can keep track of it all. I am also loading in a bunch of leads which, I will see if I can turn into opportunities for everything that I am doing (vaguely described above). Also, I have been talking to Andris over at Gradient Racing to see what support would look like for 2019, we are planning a test day in January.

Signed up for Sebring!

Registered for Sebring, Feb 01-03 really looking forward to driving at this track, I plan to run the Triple Trofeo this year: Sebring, Road Atlanta, Road America, plus a couple others: COTA, and Watkins Glen (Barber didn’t make it on the schedule for 2019). Time to start getting ready, I am going to get the Ross Bentley, and David Murry webinars. Need to get going in iRacing as well.

Ready for ‘bama

Super excited for next week, at Barber Motorsports Park!


Some last minute tweaks to the livery: got the Longhorn Racing Academy, and the Oakhill Wellness Center logos on the car! Thank you both, and thank you to TPWS for their continued amazing support! Also, very excited to be sharing the car with Colten Miller, we drove together at the Porsche Driving School, and were consistently sharing the 1, and 2 spots throughout, he is on a path to “convert from dirt” and will be driving the Enduro with me! Transportation is locked in, fuel is on the way, logos are done,  got some new number panels, car is ready to go, and I have been getting some good practice in on iRacing. Additionally, I have been  really putting it in at the gym, to make sure my endurance is up, lots of cardio, and high rep weight workouts, 6 days a week. Can’t wait to get out there, see Colten, work, and have fun with Chris, and LeAnn, maybe get to see Cass, and Sherman, and drive that amazing track, looks like we might get rain, which I love, finally a chance to put some time in on wets, might put in a track order for another set with Frisby :-). The logistics on this racing are intense!


Racing Simulators

A racing simulator is a really great investment, no costly consumables, total freedom to try any line, with no fear of breaking your car. I use iRacing as my simulator of choice, pretty sure it is the de-facto standard at this point, it is unbelievably detailed, and exceedingly realistic.

As with your car, you can really choose how far into the simulation to get, with how you add/modify your setup. Some people choose a complete cockpit setup, some leverage a VR rig, others have a completely modest setup, like me.

I use a Logitech G920 it is reasonable priced comparatively, and has a lot of the functionality I need. I used this setup to run the Porsche GT3 Cup last season, combined with Virtual Racing School (VRS)  a really great experience with both the series and the VRS system. I think the VRS datapacks are phenomenally valuable, data capture, analysis, video, and download, I learned a lot from trying the different setups, and watching the videos.

Right now I am using my simulator to learn the Barber Motorsports track for the Porsche Driving School that I will be attending in December (see my previous post)
