  1. Why is this necessary? Half the point of self driving cars is that they can go slower because I don't need to focus. Go 40 mph (64 kph) for all I care. I can be doing something else. I don't need to "hurry" at 70, just get me there.

    But you don't want half an hour's trip to become one or two hours. If the autonomous car is crippled because it's lost long range sensors it's totally reasonable to force it to stop rather than slow down everyone on the road to 10 mph. Though I hope they don't do anything so silly as to ban vehicles with redundant sensors from operating in degraded mode - that's kinda the point of redundancy. I'm not sure why they have to make explicit rules about this, it sounds like the AI version of the "self-integrity" check we should do before getting behind the wheel. Like if I'm drunk or on drugs or too tired or dizzy and at the risk of fainting or suffering from vision problems or whatever, don't drive. You carry the legal burden if you drive anyway, so do they if they think they can wing it without the full deck of sensors.

    If you make accessories too expensive, you end up putting yourself in the price range of real laptops running Windows while holding no real competitive advantages. No thanks.

    Well $99 for a pen is pretty normal... but $200 for a keyboard is crazy. I mean it starts at $600, if you go for the base model that's 1/3rd of the cost. For that you get the screen, CPU, GPU, memory, storage, wireless etc. and then $200 just to have keys... Surface takes $129 for a type cover, Apple $169 so ~$150 would be in line with the competition. I know they make money back on accessories but when you make Apple look cheap you have a problem.

    Iirr the gyroscopes all have issues with their gyroscopes' bearings, that were not discovered in earth-based duration tests. Cosmic rays erode the surface of the metal ball bearings, causing them to fail eventually way before their predicted life span. They changed to ceramic bearings since which solved the problem.

    They've found several things:

    One lesson learned was that gyros assembled using pressurized oxygen to deliver suspension fluid were prone to failure due to electric wire corrosion. Gyros are now assembled using pressurized nitrogen.

    But ultimately all the gyros were replaced in the final service mission in 2009, before that they were also replaced in 1999. These new ones were supposed to last longer but it seems ~10 years is still all we get. I wonder if the Dragon can be retrofitted for spacewalks.. I don't think you could use the same airlock as for docking, they'd need full vacuum spacesuits and June next year is just supposed to be a test flight...

    Even if radiation on Mars surface is limited, the computers still have to survive the trip from Earth to Mars.

    Well if we're assuming it's a manned mission it'll have to have a radiation shielded human habitat that can keep it under the 1 Sv career limit. Since the weighting factor is always >1, that's less than 1 Gy of radiation. That's there and back again so less than 0.5 Gy on the way to Mars. From what I understand that's not a whole lot, particularly since you don't have to worry about transient errors or jumping currents during operation just structural damage. You take them from the habitat, bring them to the deepest level of your Mars bunker and you test them. Sure a few might be broken but the cost/benefit might favor just disabling broken cores or just bringing a tray and leaving the super expensive rad-hardened stuff to probes and rovers.

  10. It's really easy to overwhelm a computer with sensor data though, which is kinda the point of the rover being there. CERN is producing data at about 25GB/s and even after specialized selection and compression they now have >200 PB stored. Considering the very limited bandwidth back to Earth of only 100-250 Mbit/day (= 12-32 MB) I'm pretty sure they wish they had more CPU and more memory to pre-process it more and maybe derive its own results like say a 3D map of the environment both for itself and to relay back. Of course I'm sure they'd find ways to work with 16MB or 1MB if they had to, but I'm pretty sure this is an area where more is still significantly better.

    Been there, done that and it's been a mixed experience. The short version is that it works real well if you are converging on a long term solution, you do an initial implementation and the tweaks to the code happen less and less often with less and less urgency. If what you want is really Excel - like, the flexibility to just alter a formula and hit save - you're probably going to be disappointed if you have to go through a standard development process of requesting the change, describing the expected outcome for TDD, pass it through DEV-QA-PROD gates and so on. Either that all the process guys are going to go nuts that you start doing ALTER PROCEDURE directly in production, even though you're technically not worse off than Excel was.

    We actually ran it that way for a while, turnaround time from request to completed change could be anywhere from ten minutes to two hours, it was simply tweak the code, rerun the calculations, ask if it looks correct now. And despite you might call that process reckless we delivered quickly and cleanly effectively combining business skills and technical skills. Then somebody from the bank and insurance industry came in, no code change without first a request in JIRA, prioritized by the product owner, assigned in a sprint, formal test cases written, code developed, passed through QA, branched into a release... I need it by end of business hours became you can have in three weeks. I wonder why they just read out all the raw data again...

If they were an industry with that rate of faulty product we'd pull it from the market and fire the QA department. Personally I'm not too worried because it's not enough that there's a bug, there also has to be the conditions to trip the bug and most of the time you'd probably notice it earlier through near-misses and lesser accidents. Once they have something resembling a fleet they're going to see very quickly if there's a spike in problems and you can react to it. With humans you more or less just have to accept that's how people are.

  14. It's easy to log millions of miles of road when you are the one choosing which roads to drive and when to drive. Proper independent testing needs to test out when those cars will fail, not just that they will work well under expected conditions.

    While that's kinda true, you run into all sorts of drivers, trucks, bikes, trikes, bicycles, pedestrians, wild animals etc. unless you're extremely selective about where you go. I mean the road artifacts aren't that many, sure if you plan a route with no roundabouts or train crossings you never do those but there aren't that many "fixed situations". Most the crazy stuff happens at random due to traffic, you can't plan your way out much other than road conditions.

    Alerts issued by the President

    I mean it is natural that it's the President addressing the country in a crisis, but they could have just called it "National Security alerts" for example. Like you can't opt out of the warning that WWIII just started. It's kinda hard for me to think of a "critical emergency" that doesn't fit any of those three.

    Well that could certainly happen but it's a risk for all codecs or indeed software in general, they've done an IPR review to make sure it doesn't infringe on the patents of their competitors in the HEVC camp so it'll have to be a surprise contender. But if you look at the Fortune global 500 they got #11 (Apple), #18 (Amazon), #52 (Alphabet/Google), #71 (Microsoft), #92 (IBM), #146 (Intel), #212 (Cisco) and #274 (Facebook) on board. I think they can afford a few lawyers to get the patent declared invalid or not applicable and if that fails a big payday for a patent troll is still pocket change for them. And if it turns out AV1 doesn't infringe your patent and that's the next dominant standard well too bad your patent is worthless, it'd be a pretty big gamble.

    Long haul bandwidth is expensive but caching is cheap and the last mile cost mostly installation and maintenance, so there's not much savings from multicast over unicast from a CDN. If it wasn't for copyright you could set up a super effective simple, open LRU cache for torrents, every time you download externally the ISP caches the chunks. If one chunk = 4MB then a 4TB HDD = a million chunks and you don't need any redundancy. Next person who downloads only sends the hash and gets it right from the ISP's network at max speed. You could even do multi-layer and have a half-PB storage pod before you use any expensive links like undersea cables. For uhh... Linux distributions, sure.
