This started as a solo side project: a real-time satellite tracker (satradar.com) that shows every active spacecraft orbiting Earth — Starlink trains rising over your horizon, the ISS passing overhead, the GPS constellation in MEO, weather

I feel like I’m missing a step here. So his tatoos showed and someone who happened to know about this guy happened to notice? Does he have a particularly distinctive tattoo? I’m not rejecting the claims in the article, but they sure are pre

This is specifically about the GM build which is necessary for final builds, validation, and submission. Often developers have at least a week to do final checks and submissions with this build.

This is David. I made Nikola. Glad you like the app! Happy to answer any questions you or anyone else has on the data / research here.

Yeah I'm not sure what the discrepancy is. This afternoon I'm going to dig a bit more into my records. In my data right now I see a few examples of an $80 purchase match to $56 in proceeds (70%) matched to $56 of a refund. I can&#

This does not match my experience with my App, Nikola. I've been able to match up the transactions and refunds as 1 to 1, price-wise.

Agree with the app store being better than anything that preceded it. That said, it's not 2008 anymore and Apple should adapt. What happens in reality is developers either capitulate and / or sneakily separately contact their user

I make an app called Nikola that's seen data from a few thousand Teslas. The short answer is there are some identifiers, but they're basically impossible for outsiders to track. Tesla is making modifications all the time. From wha

I wonder that too. My guess is there's an outlier datapoint or two there messing with the average. I didn't pull out outliers. (Since the data is smoothed, an outlier datapoint could influence speeds 2mph in each direction)

This would seem totally reasonable to me. It'll take more time, but I can also dig in and see the extent of the battery heater use. My guess is it's often cold enough for the battery to need to warm up to be efficient, but not col

Alrighty here's the first graph. Note that this is average speed, so any trips with an average speed near the right by definition have some parts of the trip faster than the average, so the actual drop at 80 mph isn't quite as sev

seems like an apt comparison. Something I forgot to mention here is that the temperature also plays a huge role. I've recently started collecting more temp data, but don't have a big enough sample size to say anything definitive b

Another fun fact on practical drain vs. EPA drain: While I love sentry mode and think it's a great feature, it keeps the electronics awake. In some cases this can cause double digit per day mileage drain. Tesla has clearly been working

I cover this a bit in my post about the data I've seen in the 1000+ Tesla fleet that I track with Nikola. 75-85% is about I right.

by davidwhodge 6y ago
I make an app (called Nikola, not the truck company) for Tesla owners that has seen over 5 MM miles driven on it. I did some quick queries to validate actual range vs. EPA range for those curious. My general takeaway is to see the EPA range

I didn't speed up the video. That is the original.

Yeah it was by the Transit App guys. They do good work. Chronologically, Apple's transit maps launched first.

Apple removed transit before the Embark acquisition.

by davidwhodge 9y ago
I am one of the Embark founders. I'm no longer at Apple. Our acquisition actually ended up with the spirit of our product living on in a way that I am proud of. At Embark, we innovated by taking a regionally nuanced and tailored transi

Requiring input twice as input validation has a fair amount of use already, like with email addresses, so it doesn't seem super unreasonable to think that's a motivation for this limitation. Also, while it sounds silly, disabling

Single data point here, but I'be heard of BMW doing work or even taking back cars under NDA.
