Oh my. My son is 7, and I know time with him will fly by. But realizing I can count the childhood Christmases that we have remaining hits me so much harder than knowing his childhood will fly by in general

I savor every day with him, even when I'm busy and a bit frustrated. I tell him that as well.

Reading the opening part of this hit me in the gut.
The dominant search portal in Japan until very recently was Yahoo! Japan, which runs its own AMP cache and is a product of Softbank. The dominant search engine in the US is Google. These two companies hold no significant investments in each other.
Sure, TVs are much harder to make than mattresses. I agree completely. But that doesn't explain why mattresses are so expensive and why we have 500 mattress manufacturers and obfuscated models and prices. In fact, your line of reasoning would lead to the opposite conclusion: Mattresses should be cheap, a commodity product dominated by 2 or 3 manufacturers who eke out a few percent margin, selling at a standard price. But that's not what we see.
My thinking is more around using thorium cycle nuclear reactors which consume almost all their input material [1].

1T of thorium produces the same amount of energy as 35T of uranium or 4166000T of coal. 83% of the waste products are inert, and 17% require only 300 years to reach background levels of radiation. Much safer than uranium cycle too.

This technology is very promising IMO, though given the general attitude people have towards nuclear, it's not surprising it is underdeveloped, more research is needed.

I didn't necessarily say blockchain. Cryptocurrency and the blockchain is the incentivization structure, not necessarily the end product.

I agree. Blockchain only makes sense for things that require immutability which many applications do not. OpenBazaar is a good example of one of the applications I was thinking of.
How many car drivers do you think are familiar with the details of how plane autopilots really work?

If Tesla had called this something like "lane-assist adaptive cruise control" I think your average Joe would have had much more realistic expectations around how the technology actually functions.
Exactly, right? That's what DI/IOC allows you to do. You can test a component where the variables always return simple deterministic results for one unit of code, or/[preferably] and you can also have a set of tests where you integrate all components.
That's not a crash warning at all. That is the usual warning ~ every minute to jiggle the wheel if you don't hold the wheel firmly if it can't detect you holding it.
The only place $200k a year tech workers can’t afford a house is the SFBA. Literally everywhere else it’s doable with a commute (a shorter one than SFBA at least!)
Hate to say it Tesla but you ain't ready for primetime. Neither is Uber.

Waymo is on a whole other level.

But I really would love to see more collaboration rather than competition in this area where safety is critical. Pardon the pun - why does everyone need to reinvent the wheel? And also encumber each other with patents?

Open source beats proprietary competitive stuff like this.
Extremely hard, the superconductors are a ceramic that is very brittle, it's quite hard to make a nice wire out of it. If a single break in a long length ruins the whole stretch then scaling up would be massively challenging, you can't just rely on melting and cooling to nicely even out issues during drawing a wire.
Texas and California; I wonder if that's a clue too. If so, it'd be very interesting, especially at a time when Waymo is now the only one left with a clean sheet. I wonder how far away Apple is from a product?
> At some point there really needs to be a legal discussion about whether Tesla's argument that the driver must always be alert and responsible for the car is a realistic standard in which to hold people when semi-autonomous systems are engaged.

It seems completely predictable that it wouldn't be, especially when they call it "autopilot."

> Does that not trigger an audible alarm by default in a Tesla

No. That's a standard warning that triggers every few minutes if the car can't sense your hands on the wheel. If you don't place your hands on the wheel at that point, then there will be an audible alarm. If you ignore that, the car will slowly reduce speed and come to a halt.
Little military application from a near limitless supply of energy? That sounds like a lack of imagination.
Completely agree that it depends on the ends and means.

In pretty much any issue we're always going to have to work with people who have differing motivations than ours, and motivations that we don't agree with. I think you've got the right question in asking why the motivation here disqualifies the end goal.
A human sees signs at 7s and 24s and the (admittedly not very clear) split of the lane at 27s as well as the yellow sign in the distance indicating the divider, while the autopilot sees a solid white line on the left and continues following it.

It probably would've been fine if there was another white line at the split, like this (marked in red here):

https://files.catbox.moe/10p2hh.JPG
Well, why would they do that unless the regulatory authorities made them?

Is Waymo really "there"? It seems like everywhere I turn I'm seeing things that suggest that all of this technology has been hyped far beyond its actual capabilities.
Toronto (Downtown) as well / rural Ontario.
Not unless you ignore it, then it will beep, then flash red. I think it doesn’t make an audible sound initially so it proves you are paying attention the whole time rather than only when it beeps at you.
> I want to know if the car braked automatically, or the driver had to brake to avoid colliding with the barrier.

You can see from the dashboard icons that he disengaged the Autopilot (by taking control). If it had detected an imminent crash it would have made warning sounds.

You can test all you want on a test track, but there is no substitute for real-world driving conditions. With AI and ML, you'll get what you measure -- a bunch of self-driving cars that pass the tests perfectly but are unprepared for the real world.

Normally it's fine to test by using models of the world rather than the real thing. But in the case of self-driving cars, driving conditions are too complex to simulate and people could die if things go wrong. My point is that we are left with a problem where the only viable test case is the real world, but it's likely that after a few more incidents people will favor banning self-driving cars rather than letting them improve at the cost of human lives.

> Why are you trying to build up objects and pass them into places?

Well, that place needs those objects to do its job.

> When / why is that ever a thing that someone needs to do so often that it becomes a concern?

In web applications, at least, you find yourself with a few controllers, which all need a few services which all need a few repositories to access the database... I guess you can see where this is going. Declaring in your class' constructor that instances need an object of `Type` is the less repetitive way of saying that an instance of a class needs something. Writing the code that builds objects and passes them to your constructors would be quite repetitive.

Which would be foolish on their part, since it would equate their system with that found on other cars. The systems found on other cars are garbage to the point of being unusable. The system that Tesla has is in a different class.

There's more money and power to be had by taking control away from people.

Fundamentally that is what's going on here. This is a massive power grab. This is convincing people to give up control of their transportation under a facade of improved safety and convenience.

Imagine streets full of powerful multi-ton wheeled drones relatively few people have control over the software operating.

Ignoring conspiracy scenarios, just imagine how 0-day hacks of that system manifest.

None of these situations are possible until you convince everyone to take ownership of one of these robots, or at least accept and utilize a ridesharing fleet of them.
The materials probably aren't quite that cheap, and due to the bulk (a queen size mattress weights about 50-70lbs) there is natural price floor just of shipping expenses.
If I was driving on that stretch of highway, I'd be pretty confused by the line markings. I wouldn't crash into the barrier, but I might drift towards it a bit. The lack of a solid white line on the right side of the chevrons is dangerous and inexplicable.

That said, self-driving cars have to be able to handle poor markings like this.

The 2400-year-old opinion of a specific philosopher, brilliant though they may be, does not necessarily reflect reality. One of the harder mental blocks I had to get through with philosophy, though it seems incredibly obvious both in retrospect and to those who haven't yet encountered it, is that philosophers write with no authority on metaphysical matters; any time a philosopher says the nature of a thing is thus, they are surely wrong. This is contrasted with technical matters, where it's possible and indeed common for our intellectual giants to describe things precisely as they are. I mean this as no slight against philosophy, nor to denigrate its utility, but as a simple observation that your mode of engagement with the material must differ; see the common interpretation that reading the philosophical corpus is more like listening in on a conversation spanning the ages rather than learning a just-so list of facts about our world.
It's at one of the busiest highway splits in Chicagoland, on the Ryan where it splits off to the Skyway. This isn't a random stretch of road; this is something an automated driving system has to be able to get right.
As far as Go ORMs go, there isn’t a decent one that handles what I consider a killer feature of ORMs - relationships. I think sqlx is good enough for most, but I once inherited a project that the management wanted to rewrite off of Scala to Go. Some of the relationships were so complex that hand writing complex joins would have been challenging. Gorm came closest, but it’s “eager fetching” features executes n+1 queries rather than joins.
> this is mostly a problem with the general public's understanding of the term autopilot

In other words, it's the customer's fault. And it's arguable that Tesla benefited from this misunderstanding.

I'm starting to feel like this whole thing is a case of competitors in the auto/energy industry smelling blood in the water after the Model 3 production issues. I'm seeing a spike in "Why Tesla is doomed" type articles recently...
I was just checking out the harbor freight air nailers. The main concern I had was for the triggers, the plastic seemed really thin and poorly connected. I'll have to check out this video
According to a new York times article recently, Waymos vehicles are currently driving on average 5600 miles between user intervention.

For Uber this number was 13

5600 miles starts becoming "I need to use the wheel only 4 times a year" territory.
Christ, this video alone has eliminated any desire I may have had in getting a Tesla once and for all. For me, the one defining feature was self driving capability, but now I see it can’t even do that very safely.
My experience with a silver level ppo plan through the exchanges is that it is exceptionally good. But yes, I'm sure if you choose the absolute bare minimum coverages it won't be great.

Thank you for the fresh perspective and the thoughtful reply. I also appreciate the offer to reach out. Rest assured we are actively engaged during the events and have found support incredibly responsive. At a high level none of these are reasons for us to stop investing in our google cloud stack, nor have they caused any major outages. Think of them as quality of life comments.

Live migrations

To clarify "this is happening constantly". I meant we see live migrations happen frequently through the day. Going back the last 24 hours I see "hundreds" of migrations. We do have days where we will see 3 or 4x this number. The majority of these were successful and our logging, probes, and graphs show nothing exciting.

On the positive side of things, we have noticed a marked improvement in migration times, probe failures, and instance fatalities in the last 6 months. Where before we would regularly see live migrations take upwards of 15 minutes or longer. They are now at or under 2 minutes (With only a handful of exceptions barely worth mentioning).

I do appreciate the facility of live migration and the proactive approach googles takes to host maintenance. The 60 second notification window is just too damn short for some of our services to properly drain themselves. So instead, we hold on to our butts and hope for the best on those boxes.

If there was one improvement to live migration it would be to have the option of a 15 minute (or even 30 minutes.. am I being greedy?) notice.

Networking egress caps shared between instance and persistent disk

The edge case that hurts here is when you have a high bandwidth service that also writes a lot of data to a PD disk and the comcast style burst bandwidth throttling that happens on the instances (This is pure speculation and may have improved since last time this was investigated. The observation at the time was the throttling is a bit too efficient and hit the instance disproportionately). We have since migrated to either local ssd or tmpfs disks for these type of hosts in gce. Their sister services are still running fine in ec2 on ebs instances.

MTU

Yay! 1500 would be better, 9k would be great. This hurts when connectivity starts to see an increase in packet loss and the corresponding increase in packet re-transmission (and latency). Not to mention the overhead these extra packets incur (Those 20-60+ bytes just in headers add up quick).

TLDR wishlist

Longer notification window before live migration actually starts
PD-optimized instances
1500/9k MTU
Every couple of days on HN, I learn of something else you can't do in California. That, plus absurd rent, makes me really glad I don't live there.
Is this true? I thought other luxury car brands are now shipping with self driving of similar capabilities to Tesla at this point.

Or maybe it's just the sensors being the same...
The big shipping problem is in the warranty (i.e. if you find a defect after the 100 day (or whatever) trial period) - you generally have to pay return shipping to make a warranty claim, and it costs somewhere between $400 - $800 to ship a queen mattress across the country. [1] Even shipping to the next state can cost $100 - $200.

And assuming they agree that it deserves a replacement, you have to pay shipping costs for them to ship the replacement.

So.... you can either pay $500 to ship an $800 mattress back to the factory and hope that they agree that it's defective enough to deserve a warranty replacement.... or you can just buy a new mattress.

Makes the 10 year warranty pretty meaningless if you pay more in shipping costs to make a claim than the mattress is worth.

I tried autoplay one time then fell asleep. History showed me that it had been playing trump videos for 6 hours. Donald then followed me around for 2 months. (My hypothesis is that youtube is gradually changing all of us into ufologists.)

> What's the point of having a chain at all?

Different people answer differently, but many would give censorship-resistant currency as a use case. My personal answer is more complicated.

> If you end up scaling off-chain, then one asks why you have the PoW chain

Let me generalise slightly to include PoS, which I greatly prefer but which is also pretty expensive, and suffers from the same fundamental inefficiency problems. Obviously, you need on chain consensus and guarantees so that the payoff matrix for the offchain game is setup correctly so that honest behaviour in the offchain game is a Nash equilibrium. So that when I "pay" you some money in a payment channel you really have received it in a certain sense, and offchain payments are basically as secure as on chain ones.
The initial message that pops up is somewhat easy to miss, but the white flashing at the edges of the instrument panel gets my attention every time. It’s effective enough that I’ve never received the audible alert that comes next.

(I don’t use my phone while driving, so my experience is based on looking at the road. Maybe it’s easier to miss when looking downward rather than forward.)
It was, confusingly, a computed dashboard -- not an actual tracker.
There is another white line at the split, following the trajectory you've drawn. At the junction of the two lines, it's badly faded, but you can see at :32 and better when he looks up after :34 that the line is there, it's just not as freshly painted.

That's not an unusual road condition at all; also: you'd think there'd be some logic reconciling the line it thinks it has to follow with the fact that an entire lane of traffic on the Ryan (the left-most I-94 lane) doesn't abruptly end.
Not sure what you mean. Video drivers on Linux are finally coming together for all the main players. Nvidia's proprietary drivers are still good, Radeon's free drivers are very competitive and Intel free drivers are still great (though suck for gaming).

Wow, that video is pretty damning.

(a) Even though the driver was getting a warning to put his hands on the wheel, the car should NOT continue driving forward and piloting itself at all with no driver response and insufficient certainty to continue navigating itself.

(b) There was a very obvious hard barrier right in front of the car. Why didn't the collision avoidance detect it and halt the car?

(c) The car was clearly "pulled" to the left by the bright exit lane stripe and missing highway-side stripe.

Simply following stripes seems an absurdly primitive and unreliable technique to me. The fact that the car could be "distracted" this way suggests to me that it isn't getting (or making good use of) a lot of information that should be available to it-- like the behavior of other traffic, the presence of other obstacles and roadside geometry (like the ignored barrier, which was on a collision path), the trajectory on previous trips (and any conclusions drawn then under better conditions), the road sign which indicated a fork (and which was also itself on a direct collision path), the crosswise striping in between the two forks which the car was driving over, and the striping on the other edge of the lane, and the lanes beyond, which followed the correct trajectory.

Each of those things is a significant clue as to the real path of the lane, and are all machine-detectable and processable pieces of information. Even with nontrivial uncertainty about each of them, the totality of information, IMO, should be more than enough to clearly discern the correct lane, especially if efficiently used-- Kalman filter-like information synthesis can take a lot of very uncertain information and synthesize a very certain picture.

Instead the machine ignored the holistic picture and "target fixated" on the stripe. This apparently has a disappointingly long way to go before it is a reliable system.
