Indeed. It was many years ago but I clearly remember he used a lot of volume and language on the initial call. It was followed a few days later up by an equally-memorably note that started with 'HERE IS WHERE I EAT CROW' in all ca

Ah, adventures in 'not quite as random as you thought' land. 1) I remember building a game in 90s where the locations of resources on a 2d game map were generated by successive calls to random() (and then were probably mod 1024ed

Not anymore. At launch the road networks was from TomTom, but for years now they have been in the process of completely redoing it from scratch themselves. From a quick Google search it looks the new data rolled out to Germany a couple of m

I think managers being extroverted (or, if you read this thread, useless narcissistic status-seekers with bad home lives!) is part of the answer, but not all. Another simple explanation: For an individual dev, your job might be to, say, tak

Working as an eng leader for five years in the industry gave me a considerable base of factual knowledge about the state of the industry even beyond my own company. I was just summing up my knowledge with an (I thought innocuous) 'I be

Reasonable. It's an 'I believe' claim based not an 'based on these facts' claim. But, I am more informed that most as I spent five years in the industry leading all algorithm/ML development for autonomous syste

Yes. The liability factor is a great proof point, but the real tech innovation in my mind is not the self driving code, but instead the attack on the fundamental problem of building a model of where and when their stuff is trustworthy. As y

The conversation is complicated because LIDAR is used for many purposes in self driving. It's used for localization, it's used for objection detection, it's used for classifications, it's used for understanding occlusion

I believe that Tesla is ahead in the self-driving industry from an overall technology perspective. What they have failed to do, however, is to tackle the problem of when and how much the user can actually trust their system. This leaves

I think that as car perception systems start to have understanding of the 3d scene (i.e. not just adaptive cruise longitudinal controllers) joint control of the brakes and steering will becoming standard for accident avoidance and will be a

You get it correctly. Deep learning isn't inherently good for cases where you need to be right 100% of the time. But we don't have a better tool so the industry is trying to see how far they can push it. One big open question in s

I don't think it's magic, but: 1) Stopping distances go up as the square of speed, so 40mph has huge advantages over, say 70mph. 2) Survivability of accidents at 30-40 are way higher 70 (unless pedestrians are involved, in which c

This was interesting to me so I spent a while this AM playing with a Python simulation of this effect. I used a simple process model of a normally-distributed underlying 'true skill' for participants, a test with questions of vary

Yes, he is popular. Yes, he loves click bait. No, he does not have a deep understanding of technical subject matter. All that said, as a journalist he seem to genuinely try hard to get to the bottom of technical issues relating to Apple and

Ha, you totally got me :) In my defense, my comments were meant apply to mainstream world/national news. If you have a specific interest that you want to keep up on, that's a somewhat different set of tradeoffs. But, even then, I

I quit the news roughly 20 years ago and never looked back. The way I explain it to people is that the news is simply a form of entertainment that I don't really enjoy. I'm sure it's been pointed out before, but the news is a

Good result for Pragg for sure. According to their ELOs, and accounting for the fact that Pragg was playing black, this would be predicted to be a 4% occurrence (~30% odds of draw). So, yes, unexpected, but not exactly stunning given that t

You comment makes sense if I was not hooked up to the grid. But I am. So, if my family conserves, that energy we save offsets someone else’s coal-generated energy and helps the environment. But I have zero incentive to so do because of laye

I just moved into a new construction house in Colorado with a substantial (23kW) solar installation. It’s been interesting to see how much, in the words of the author, ‘feeding bread to pigs’ I have ended up doing. The solar installation (w

This is a great point about a potential downside of the 'Free Drive' decoupled crank concept. By decoupling you also get rid of the coupled inertia of the bike/rider and petaling becomes weirdly inertia free which most people

I love climbing bikes but if my ride starts with a fun descent it's still enjoyable even though I haven't paid for it yet :) But I appreciate your point about the high efficiency of bikes. On flats or downhill even a casual peddle

I agree with the overall point that e-bikes can hit higher speeds more easily. But those speeds on normal bikes aren't the sole domain of experienced riders. Going down a two or three percent grade at 20 or 25 mph is something that a n

If they tell you this there is a 99% chance is it BS. As someone elsewhere in the thread points out, it's just a manager not wanting to have an unpleasant conversation and saying 'hey, it's out of my hands' with the assu

Yes, it's a negotiation and the negotiation is bounded on one side by 'what the job/employee is worth to the employer' and the other side by 'what the employee is willing to accept.' My point is that your previ

In practice future salaries are heavily based on current ones because that is what the new employer is de facto negotiating against. Very few people, in my experience, are willing to entertain a new job with a salary much lower than their l

I got my report but the data was way off. Base salaries reported too high (~2x), bonuses in the ballpark (but wrong), and RSUs reported too low (~2x). There is a lot of detail in the report that gives a false impression that they have the e

Obviously no one should bankrupt themselves spending more than they can afford on a monitor, but I agree completely with the sentiment of the parent. In early high school I scrimped and saved and purchased a NEC 3FG flat CRT (13 inches I th
