Where do you work?
quenstionsasked··on How Discount Brokerages Make Money
Anyone knows what is meant by:

"(Again, hate to belabor a point, but Wealthfront charges 25 bps all-in (on top of the underlying ETFs) and every customer knows it"?

quenstionsasked··on Apple’s new Find My app will find your devices even if they’re offline
This link just says that the M7 is still active after main phone has shut down. Nothing about inertial navigation.
quenstionsasked··on Apple’s new Find My app will find your devices even if they’re offline
Where were you going that you didn't have GPS coverage for 30 miles?

GPS coverage works even without Network/WiFi coverage. I find it very, very unlikely inertial tracking using iPhone inertial sensors would be accurate up to 30 miles.

Could you provide a source please on the fact that iPhones use inertial navigation for predicting location (either public or private apis)

quenstionsasked··on How well do London buses match the timetables?
This doesn't hold. The timing of the VPN code widget is not a random variable, but rather fixed. Thus, sampling a random inspection time of the widget has equal probability of being in the 0-30s bucket as it does in the 30-60s bucket.

For a bus, the intuitive explanation is that if you were viewing a timeline, the biggest parts of the timeline would be the "late" buses, and thus you're more likely to "inspect" (arrive at the bus stop) during one of these longer stretches.

quenstionsasked··on AmpliGraph: A TensorFlow-Based Library for Knowledge Graph Embeddings
Cool. KGE methods are becoming more and more useful as companies are trying to find ways to interface some internal knowledge graph with machine learning techniques. I expect this space to grow substantially!
quenstionsasked··on Ethiopian Airlines 737 MAX Investigation Preliminary Report
MCAS issues nose-down, speed increases and nose pitches down. Nose never pitches back up. Plane crashes.

Sure, maybe some complex combination of maneuvers could have helped them out of this but there's really everything pointing the blame at this one system. Pilots did what the boeing manual suggested (even included at the end of this report).

quenstionsasked··on Apple to contribute to U.S. teen's education for spotting FaceTime bug
It was a long time ago (2013). Issue was fixed in the next iOS milestone release, but they gave no recognition at the time and no follow up besides a "thank you for reporting this" email.
quenstionsasked··on Neural Networks, Manifolds, and Topology (2014)
Haven't given it a lot of thought, but isn't his vector field idea somewhat similar of an approach to neural ordinary differential equations?

Reported an iphone lock screen bug and received nothing. Thanks apple.
quenstionsasked··on Mystery Math Whiz and Novelist Advance Permutation Problem
Haven't taken the time to read through this properly so forgive the question - but is this any different from the above problem?

And if so - if someone solves this programming task on leetcode have they not then also solved the permutation problem from OP?

quenstionsasked··on Principles of Algorithmic Problem Solving (2017) [pdf]
I remember being in a Spotify hackathon with Johan many years ago. Fantastic problem solver. Happy to see his work here.

You wrote on my blog post on the hackathon at the time (2011) that I had "some promise for algorithmic problem solving". Really inspired me to dive into CS.

quenstionsasked··on SEC Sues Musk and Seeks Ban for His Tweets on Go-Private Deal
I'm very curious about the Stanford thing. Do you mean that he was never admitted? Or simply that he never officially enrolled?

I tried my hand at googling this but found nothing but re-hashes of the same story of how he left after two days.
