I don't agree with their beliefs either but do you really feel comfortable having one side of the political spectrum be the arbiter of what is "right"? We may disagree with them, but we (assuming you are as well) are in america where you are allowed to hold beliefs (as long as exercising those beliefs don't infringe on the rights of others).

> So you can't argue that we should forget his bigotry just because it's old and not relevant anymore.

If some people still hold some of those beliefs (again, I am not one of them), doesn't it seem even less good to penalize someone from the distant past for holding that belief?
Amazon bought Kiva a while back now to do robotics for them, and it's used heavily in their warehouses and facilities around retail side. Anything they can automate through robotics, they try to as robots can work 24x7 (other than maintenance requirements) and over their life span cost less than human workers. They also sponsor engineering competitions around trying to make generalised picking machines. It's good PR for them, and although unlikely any time soon, someone _might_ have an inspired idea and solve something that has vexed experts for a long time.

https://www.youtube.com/watch?v=TUx-ljgB-5Q shows some footage of the robotics they use.
I see. I suppose that might make sense. I would personally trust the ThinkPads to have higher build quality than a non-battle tested new brand.

But, then again, I would also consider the ability to change a faulty part as part of the build quality equation, and as such rank apple products much further down than most.
Startup Idea Feedback: Chckup – Expedia for Vet Clinics
I have a new startup and we're launching the prototype on August 2. I was wondering if anyone had any feedback on the current concept and execution (see website chckup.app for more info)

I'm open to learning as much as possible and getting as much feedback as possible. Would love to speak with people more who are interested.

Thanks Everyone!

Thanks a lot!!! I really mean it!

This might change everything for me. I'm already using MariaDB+MyRocks and Clickhouse for some special/dedicated tasks, but I was really missing a good DB for normal/typical OLTP tasks.

So far I used (as mentioned above) MariaDb+TokuDB (but the optimizer of MariaDB can be a bit crazy from time to time), had multiple times during the past months thoughts about PostgreSQL but the lack of hints always made me take a step back from it => this addon seems to be exactly what I wished for.

Looks like that my weekend will be all about PG - the last time that I set it up its version number had a single digit => cannot remember anything anymore... .

Again, thanks for the hint :P

I think that you made a mistake with the solar farm area comparison. 10 megawatts per square kilometer (annualized, already accounts for night time and clouds) is a decent rule of thumb for solar farms. So 84 MWh/day (3.5 MW) would take 0.35 km^2 of solar farm. If solar farms were completely tiled over with 20% efficient panels achieving 28% capacity factor, 3.5 MW would occupy only 0.0625 km^2.

But offshore wind still has advantages in that it doesn't occupy on-shore real estate and can supply power at night without batteries.
And here's the HN discussion on that thought-provoking post:

It looks like a bug. The unhappy path contains both `node++` and `node=node->next`. Note that this is in the code following "Let’s go back to the code we showed for value speculation in C:", which is actually different from the preceding code it's supposed to be a copy of. I guess it's a typo.
The "metaverse" is scam. Talking about it is just a way signal that you're a lord not a serf, i.e. "I can get a girlfriend, but most can't and they'll use the metaverse to drown their sorrows."

Facebook should make something they themselves want. I want an iPod not a VR concert.
Disclosure: I work for an established (maybe?) competitor to this idea; I say maybe because it's really not clear what you do until I read most of this thread, nor how you do it (or what's planned vs. available).

First, Welcome! This is a huge arena and I think there's a million, nuanced areas for companies to tackle and really focus on amazing merchant experiences. THis is a very big (and growing) pie.

Second, I think you'd benefit from trying to increase the clarity of what you do and the value proposition, plus how it all works. For example, I'm not sure how you can provide broad-based api support for 3rd party developers without script injection or strong webhook support, but maybe you've got a new approach? I also admit to being skeptical when you mention a feature as surpassing platform rate limits; we have a continual pain point with shopify, query cost calculation and throttling as an example.

Third, we also use a platform-agnostic solution, but then build internally on this before exposing client-facing services. After several years we don't support nearly as many platforms as you; how do you stay on top of all these unilateral changes? Just shopify keeps us on our toes, and some of the ones you mention have little critical mass making them unattractive.

Finally, it would probably help adoption if you at least gave some indication of what your pricing is going to look like, even flat rate or %, or totally custom... You're asking people to build solutions on top of your product without any sort of idea of what the long term ramifcations look like. That's a hard sell.

Good luck with the venture!
It's usually wrong to assume that expressions that ultimately have the same effect (such as a || b and a | b when both a and b are simple booleans, so no side effects) will make the compiler generate different code depending on which variant to use.

The compiler knows that both variants resolve to the same result with no side effects, so it should try to generate whatever code is more efficient. Depending on several factors, that may be machine code that effectively exhibits short circuit behavior or not, for either expression (so even a|b might end up having a short circuit on the lowest level).

This would be different if you, e.g., sprinkle some volatile keywords (which effectively introduces side effects), but then you'd probably still want to take more care and split the expressions up, unless you really don't care about the order of your forced memory accesses (i.e. if I recall correctly, there is no guarantee that a|b will access a first, then b). And that's not even going into barriers.

Which is why companies started moving into other questions that have no relation to your job, like designing youtube. There is such a slim chance that you'll end up designing youtube at your tenure there, in a team of 2...that it's probably more likely to fill a jet with balls. Yet somehow people are not bothered by the design youtube question the same way they are about balls in a plane. It's true that the youtube version has technologies that are somewhat related to what you'll be doing, but in practice you won't have the opportunity to choose that many technologies for a single product, you'll be a cog in the machine anyway.

Fun fact - when your eyes are performing a saccade (ie, moving around a scene) they discard a lot of detail in the visual input to avoid blurs ([0]).

If you could detect saccades and dim/turn off the lights, I wonder what the perceptual experience would be!

Why are you surprised?

Whenever some form of immersive "universe" under corporate control is described in fiction, it tends to be a fairly dystopian tale. Every so many years VR is going to "finally be here" ... and then it never materializes. Add to that the head of the corporation in question is a hop, skip and a jump away from near Bond-villain status.

It would be remarkable if the gut reaction of most people were not negative. Which makes your surprise at the negative remarks remarkable.
This is a terrible policy. Anyone who has kids in high school and sees the lengths people go to game their grades will tell you this.
An interesting little tid-bit: I've read that Feynman was sitting in a truck at Trinity, and I think he was alone.

This is a monumental issue in how American cities develop.

I'm from the south and am currently moving from one southern city (Durham - which is near Raleigh - NC) to another (Nashville, TN) and it's depressing to see how both places keep making the same mistakes (Nashville is maybe 20 years further down the road to failure than Raleigh, though).

What are those mistakes? Designing all these unwalkable neighborhoods filled with single family dwellings with no cross streets or any retail corridors, then cramming them in along "strips" that connect them to the Old City and accumulate strip malls (eventually, holding so much traffic that they are a nightmare to navigate).

So what you end up with, is the Old City has an actual grid of sorts, with cross streets and some walkability, with commercial near residential, and feels vibrant. But most people simply can't afford those areas, because they're so desirable for the people who recognize the value of this.

Since the old areas are so expensive, most people have to buy into one of the aforementioned crappy new neighborhoods, and suffer all the subtle ill effects of being isolated from most other humans by walls of traffic. When individual developers buy these massive swathes of land in (formerly) rural areas, they optimize for the short term profit they can make from selling the new homes, and nothing else.

As more of those crappy neighborhoods pile up, the traffic gets worse, and getting to/from the core parts of town becomes more and more painful. In this respect Raleigh fares better better, but only because rather than having one city center, the Raleigh area has many (Chapel Hill, Raleigh, Durham, and various other small towns). The web of sprawl grows between these places, but in each core is a small grid with retail, which means that as the megalopolis fills in all the gaps (rather than growing outward in ever increasing circles from a single center point) people can remain close to something attractive.

One big issue is that the cookie-cutter neighborhoods have no grid system that connects to their surroundings, and instead there's just limited ingress/egress from the neighborhood onto the main strips. The developers don't own adjacent corridors, so there is no short term incentive to connect to them. This creates vast areas where no retail could ever exist, because they're along dead-end cul-de-sacs which "belong" to individual neighborhoods.

I don't really know what the solution is. I don't really think humans want to live in these places, but there are no incentives to do better for builders, and real estate is treated as a valuable commodity, so here we are. In the south, where rural land is cheap, it all feels depressingly inevitable.

I'd love to see a counterpoint of a city (especially a Southern city, in a red state) that has taken a different approach to development, which has managed to prioritize connectivity and walkability in a successful manner.
Buying 1 Mibps means you can use up to 1Mibps. Paying $/GiB means you can use 100s of Gibps for a split second and only pay the $/GiB fee.

In the past i did a TCO comparison for a large spikey workload where the $/GiB cost even at list was cheaper than allocating enough bandwidth for peak events.

At small scale the $/Mibps likely comes out cheaper, but for any large company sitting on 100s of Gibps of excess capacity for an event that occurs once or twice a year, or a few hours per day is very costly and might eat up savings from p99/p95th billing.

I have a latest gen iPad and file management is a disaster. Apps are so sandboxed that either every app needs access to my dropbox or you have to go through the atrocious files interface - assuming your app even actually supports the files dialog.

Makes sense. The end state appears to be that humans should only be supervising ML that generates goal and outcome based behaviors for robots, and the machines will construct tools to solve problems themselves.

The leap from an AI model learning how to replicate a behaviour (e.g. evolving walking to solve problems https://unitylist.com/p/2id/walking-ai ) to reasoning about it in terms of actuators and physical feedback, to assembling a physical model out of a relatively small list of parts seems like a solvable engineering problem when it is broken out into a pipeline.

Those robot parts are basically a version of mechano with actuators that a model would map a behavior to, and the robots in the article would assemble them. When you look at something like Lego or Mechano as an intermediate representation to construct buildings out of, where all objects made from it are essentially a directed graph of those elements, robots designing and building robots seems like less than 20 years away.

e.g. we could functionally specify to an ML model, "produce a digraph of these element parts that has these degrees of freedom, and then load or derive a model that solves for this outcome within the domain of those degrees, where outcome is 'plug cables into a board' "
He was also the originator of the term singularity in the sense of tech:

“The ever accelerating progress of technology and changes in the mode of human life give the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue.”

I don't have an RCT which establishes this. But I'm not the one who asserted that the Pfizer or Moderna vaccines prevented transmission. You have the burden of proof in this situation. Hence my reference to the astounding amount of certainty in your comment.

I think it is completely clear from the statement that you made that: the vaccines are effective at treating symptoms of covid and that they will reduce the symptomatic infection rates.

However, symptomatic infection rate and infection rate are decidedly not the same and we've know from the beginning that asymptomatic spread occurs substantially with covid.

The only way you establish the effect on transmission is with a large-scale RCT using a well-designed testing protocol. This may be hard but this is the standard.

> We also saw that investors really didn’t like the business model of being the operator, and that our heavy investment into safety didn’t translate for investors.

This is what Stefan said here [0]. Honestly I hear contradicting reasons for the failure. It could be that their investors had a different risk tolerance than Waymo/Uber's.

I guess I'm confused, sure, teleop could cover a lot of the edge cases but if there is a fat long tail you still end up with a pretty unsafe technology. The deer example is kind of a distraction and goes to show that maybe Starsky had a problem imagining and classifying catastrophic failure events. For every deer jumping in front of the vehicle there is a 10x more serious scenario that could lead to human fatalities.

After reading his posts I'm still confused about the reasons they failed. Can you list the reasons from high priority to low as to why they failed?
