From what I've seen, I believe that Fuchsia is intended to eventually replace GNU Linux based Android as the mobile platform for Google... eventually. The idea is to have a good platform for VR/AR apps (soft real-time processing / rendering), while providing a system that can be continually upgraded.

Unlike the current situation with the Android ecosystem right now, where a newly released product is lucky to get even a few security updates in a year or so, and have effectively had support dropped after that.

Compare that to the ChromeOS ecosystem, where Google guarantees 5 years of support from the time the first production on a platform was released.

How much equity should I get as a first engineer?
I'm in a bit of a weird situation right now so I'd appreciate some advice.

I joined a start-up fresh out of university as the first employee with a non-technical founder, taking (at the time) at least 25% less than my market rate. At the time, I settled for it because it is a project I was really excited about and it was a great portfolio building opportunity for me as a developer, and I was quite empathetic to the financial situation. My contribution to the company can be said to be the backbone of it, but the founder denied me the title of co-founder on the basis that I was drawing salary while he is funding the company out of his pocket. We're at seed funding right now and he's only giving me 1%. But without me, the product wouldn't be half of where it is today.

The general sense I get is that because I am young, my opportunity cost is lower and he's using that as an excuse to give me less equity. My value to the company is plain to see because I've built something that everyone (other developers, investors, potential customers) is amazed by, but I have no numbers to quantify my value to the company because we are not making money yet (due to other factors that I have no control over). I have a colleague in my boss's other company who is in a similar situation: young, low market rate, huge contribution to the company, only given 1%, no cofounder title. It's pretty clear to me that he's lowballing me and I'm pretty set on leaving, but I do want to know how much someone in my situation (young but huge contribution) should get, because I haven't read about it anywhere. Appreciate your input :)
Peter Beck is kind of famous for poo-pooing reusability in launch. That's what I'm referring to.

In part of the reuse presentation, he said, "this is a cap I'm about to eat because I've said publicly a few times the various things that rocket lab would never do so [i.e. reuse] unfortunately I find myself in the position of eating my hat." Here: https://youtu.be/joONWIGtcdY?t=501

Rocketlab has been able to execute very effectively, which is why I appreciate them. It had long bothered me that they didn't put their obviously impressive engineering prowess to bear on the reuse problem, and I'm very glad that they've come around.
> So in the end I think Elon will be proved right. Those currently investing in LIDAR-based systems will eventually ditch it for purely practical economic reasons. Those that don't will be completely destroyed in the open market.

High quality cameras are insanely complex pieces of electronics and optics. Ditto for processors capable of doing quality image recognition. Large scale manufacturing has made them cheap nonetheless. LIDAR is relatively niche, but if it proves useful to deploy it at scale, I'd expect costs to drop very significantly. The underlying technology uses very simple physics (relative to the algorithmic complexity of image recognition); seems like a solid basis to build a sensor off of.

> LIDAR is a crutch for bad software

You could invert this and say that high precision image recognition is a crutch for ill-suited hardware. The final combination is a product of hardware and software. If LIDAR is currently too expensive or energy-intensive to compete cost-wise at acceptable safety levels, that's one argument, but saying LIDAR is a crutch is just moving the goalposts from "good system" to "cheap hardware".

[edit] Also, just want to point out that RADAR resolutions are way too low to operate a vehicle safely (never mind road signage or other things).
If you can show by general arguments that engineering viability is unlikely, demonstrating physics viability is pointless.

They may be omnivores, but they eat plants only when they’re raised in captivity.
> The power questions also aren't cut and dry: if you need extra in-vehicle GPUs to support the radar+camera approach, you may well be using more power than a lidar based approach.

All current lidar-based approaches I'm aware of also supplement with radar+cameras. LIDAR isn't sufficient in isolation. GPUs consume way too much power, there's no way you can cavalierly just add more of them as a scaling solution.

> You don't actually need the safety system to pass the safety tests (that don't currently exist) in worst case conditions if the vehicle works anyway. Why optimize for the worst case first?

Not even sure how to interpret such a statement.

> I'll respond clearly: We're multiple computer vision leaps forward away from what Elon needs for success. They're easily half a decade behind Lidar based systems. And people die as a consequence of putting those systems on the road.

Custom ASICs for ML that Tesla is building is fairly well-understood tech at this point. High-end smartphones have used similar tech for years now (though perhaps an apples-oranges comparison).

Only criticism I would level against Tesla's current approach is their overly optimistic time estimates, and hand-waviness about the complexity of solving certain very complicated edge-cases. However their technological approach is quite sound.
Serious question: is this actually a concern for land animals like cows or chickens? They tend to be fed an exclusively vegetarian diet, so any bio-accumulation of heavy metals or similar should be minimal - the chain is pretty simple: sun -> plants -> meat animal. I can't say I'm aware of people getting mercury poisoning from beef, for example.

Seafood is different, since the food chain can be significantly longer and more complex.

I can't speak to how common the practice is but it's often an option on firewalls. My understanding of the reasoning behind it is that it allows the company to monitor employees usage of the network to protect from data exfiltration and malware that uses HTTPS.

It's usually done as part of a firewall that will MITM traffic on the network.
The article cites benefits in "not being dependent on arable land, water (i.e., rain), or favorable weather".

And this is speculation on my part, but I assume not needing pesticides, and going straight to the end product instead of having to harvest, store and process the plant-based food are also advantages.
If you have the time, could you link to a few (or lots) of these dead comments with absolutely nothing wrong with them? Thanks.
Yeah, that's bullshit. Energy density of renewables doesn't preclude current lifestyles. The Earth is constantly hit by 100,000 TW of sunlight, and the energy collected doesn't have to be used near where the collectors are.
I thought this looked really familiar. I've definitely seen this sometime years and years ago.

- much less land required, and can use any land (or even at sea), under any weather

- simpler to handle vats of gloop than all those leaves, stems, seeds, etc

- possibly more efficient than photosynthesis' woeful c. 1%

Obviously you're not expected to eat a plate of this stuff, it would be high-protein 'fill' for other food, pastes/sauces, breads, etc, or for animal feed

This is likely to be much more expensive than just clearing some "free" rainforest and planting soy/corn/etc, but that needs to be addressed anyway.

We need to start returning a large % of agricultural land to nature, not just stop taking more, which will mean using the land left much more efficiently and/or organically, and creating more of these direct-synthesis approaches to food production for staples.

I see a possibility that many commodity grains could be produced by direct synthesis, especially if they are mainly used as flours or feed. Imagine being able to reforest, or re-prairy (or whatever it wants to do) most cereal land.
>almost all people would agree at a high-level that minimizing suffering is an agreeable axiom

Yes, they would, but there is a weighting based on the perceived status of the animal. Otherwise we would feel compelled to destroy all carnivores, since a single carnivore can kill many, many prey throughout its lifetime. We agree that the utility a lion gets from eating a dozen zebras is greater than the suffering of those zebras. Also, note that predators, do not just kill strictly what they need for food(biggest example is housecats, though other examples include wolves killing elk
https://www.nationalgeographic.com/news/2016/03/160325-wolf-...).

Similarly, humans have a weighting function. Many people think that the utility/pleasure that a human gets from eating octopuses is greater than the suffering of those octopuses.
We've largely zoned them out of existence. I think this is strongly influenced by housing policies post-WW2 that helped create modern suburbs.

In a nutshell, Americans have a mental model of "proper housing" as housing designed for a fairly upper class nuclear family. We had a fairly high percentage of such just after WW2. Since then, our demographics have diversified away from that, but our housing stock has narrowed towards even more of that.

I'm hoping to figure out how to reverse that trend.

This happens to me too, also if you say the city and the name of the place it will definitely not find locations that are outside the official city border, even if it's 25 feet from that border. So crazy too because I can literally be next to a restaurant, ask for it, and not find it.

The other thing that absolutely drives me bonkers - Google maps keeps routing me to the back of something, like literally to the truck entrance of whatever grocery store or restaurant I am routing to. You would think they would employ ML to visually figure out where the parking lot is vs the truck entrance.
Calling it "merely the art of debating" implies it lacks actual substance. I think philosophy concerns itself with what you debate about, not how you do it.

Besides, nothing outside of dogma can "give you" a value system, but philosophy does present candidates. It's up to you to choose your own, the hope being that this is better than unquestioned inheritance of values.
Well, really, we already can feed billions. Of the 1.88 billion bushels of wheat produced in the USA in 2018, only 36% was consumed domestically. We also produced about 1.1 billion metric tons of corn last year; 14% was exported, and 96% of the remainder's domestic use was feed grain. We also produce about 20 million tons of potatoes annually, half of which is sold for processed foods and feed.

If we produced more wheat, potatoes, and oats, and used it all for food, we could feed several billion people just from existing US farmland.

Referencing three American incidents from decades ago (which, although I consider Chile and Nicaragua to be among America's darkest FP moments, were all officially -- and mostly corroborated by the historical record -- undertook in the name of national security rather than commercial interests) hardly indicates this sort of tit-for-tat commercial relations between nations is the global norm.

Still no spectre exploit (or even attempt) found in the wild. There should have been something by now.

If anybody has access to the POC code I would love to see it. Until (and probably after I see how laughable it is), I'll assume this is just a press release by some security company.

> Does it make you a better professional musician if you can play all scales perfectly at any time? Absolutely not! In fact I’d argue that you’re wasting precious practice time.

I'm not a skilled musician by any means but I have often read and believe that there really isn't anything more valuable than practicing scales. It builds your brain's muscle memory so you can play anything you imagine/feel at any moment.
Yeah, but if you look at that paper, platinum is extracted at roughly $20,000,000 per tonne--roughly the price of a single rocket launch right now. And we extract only 200 tons per year. That's a $20 billion market, but it's so sensitive to supply that nobody is rushing to open more mines.

The crux of the argument is you will still need the algorithmic complexity in the end with or without LIDAR, so it doesn't add any advantage.

I'll just paste the quote FTA:

> "Lidar is really a shortcut," added Tesla AI guru Andrej Karpathy. "It sidesteps the fundamental problems of visual recognition that is necessary for autonomy. It gives a false sense of progress, and is ultimately a crutch."

Starting in 2018, Solar Foods is participating in the ESA Business Incubation Centre Finland.

All their news is about funding, not doing. Nor does the NASA involvement seem to be more than a query.

This sounds like a food-from-methane scheme, prettied up with hype about cracking water and CO2 using "renewable energy" to get the H and C needed. That goes into a fermentation process, like a brewery.

KnipBio was doing something like that, but using methane as the feedstock. Their web site talks about future events in 2018, so they apparently are not doing too well.[1]

Calysta is actually doing it. They bought the technology from Statoil in Norway, which had a plant 15 years ago making about 10,000 tons of animal feed a year from methane. Wasn't profitable. Calysta has a pilot plant in England making animal feed, but it's been running for several years with no scale-up.

NouriTech in the US licensed the process from Calysta and has a plant in Memphis, TN. They're working with Cargill, the big US ag company. The address for the plant shows a big place with railroad sidings, tanks, and trucks, but it's a Cargill high-fructose corn sweetener plant and doesn't match the drawings of the proposed NouriTech plant.

So it's clear that you can do this, but not clear that it makes economic sense.

I did a similar exercise late last year, using opencv v4 beta and python. I defaulted to py3. And immediately had problems, even with example-ish code. Camera misconfiguration and intermittent latency excursions, IIRC. So I backtracked to the "road well traveled" of py2. Which just worked.

> straight to the end product instead of having to harvest, store and process the plant-based food are also advantages

Whatever microbiology they are using (probably yeast) will certainly require harvesting, storage and processing in order to turn into foods.
A number of the comments so far have been attacking Solein with something along the lines of “why not just eat plants”. In my mind, I see two distinct advantages of this approach as a component of altering the food production system to reduce environmental impact.

The first is that while plants are efficient at utilizing solar energy for their growth, we aren’t actually able to eat most of what they produce. Take the wheat plant, for example. It is widely cultivated partly because it is so good at producing calories cheaply. Even so, of the roots, the stalk, the leaves, and the seeds, we only eat part of the seeds. From the seeds, we will strip away at least the chaff and often the germ and the bran as well leaving only the endosperm to actually eat. Even that assumes that one of a dozen possible crop failure cases didn’t kill the entire plant before it could be harvested. The advantage I see to the Solein manufacturing process is that we can turn a far higher percentage of the gathered solar energy into actual consumable calories with far less land.

The second is that a portion of the carbon footprint of modern agriculture is transportation. The distance between where our food is grown and our local grocery store is often thousands of kilometers. If Solein could be produced in the same urban area that it is eaten in, then we can cut that transportation distance to dozens of kilometers or less.

Wow I had no idea something like this existed. I think this is something I should do, I've been flirting with the idea of escaping the city life and doing something physical, I don't think office work fulfills some of the necessary functions humans require. This will allow me to test out that theory without huge cost.
Of course, they were presumably using a mostly-stock car with custom niche sensor products, so that comparison would be a bit more favorable in production.
Great documentary - thanks for sharing
American beef is often grain fed, not grass fed. There's also the issue of cannibalistic feed. A quick google got me this video, which I only watched partway through (it indicates fish is the worst, followed by chicken and cheese):

IIRC, such things tend to accumulate most in the fat, fwiw.
I stopped going to NPs years ago when I found I could get better information via just searching for my existing diagnosis and reading the uptodate article. They're certainly useful if you're at the grocery store and need a quick prescription...but that's about it. Granted, that's probably good enough for most medical issues and patients coming in with colds.

The frustrating part is that I've found many specialist clinics that will do a one visit intake appointment with an actual MD then pass you off to the NP for follow-up visits. The strange part is that the NP is billed at the exact same rate. I'd be happy if I was paying ~50 an hour for an NP versus 400 an hour for the specialist, but that isn't the case.
Where I grew up, there were pretty frequent protests infront of the Chinese embassy. Year after year. I saw something similar at a Chinese consulate in the US once.

I spent two years in Hong Kong. There were frequent (weekly) protests at Chinese buildings (I remember one in particular that seemed to always have a crowd of people, in Sheung Wan, on Connaught Road I think?). It was always super peaceful, from both sides.
