I'd be interested in a direct comparison with similar efforts undertaken by existing frameworks; for example Torch Script[1], which aims to produce a language which shares a syntactic frontend with Python while getting all the goodies that ahead-of-time compilation gives you (symbolic diff, operator fusion, etc).

Seems to me that the primary challenge for any "next-generation" framework or language is getting people to actually use the thing. Sharing a front-end with Python and a backend with PyTorch seems like a good way to bootstrap that.

> Sorry, to be clear, there usually isn't any machine learning involved (at least not in the examples I'm familiar with), but the rest of the process is very similar.

No problem, shame though!

It seems to me there must be scope for using AI to improve this process given the results it achieves in other domains, and the alphafold result is very encouraging. Maybe that order of magnitude improvement will eventually be possible.
No? If you tried to park a car on the sidewalk you will get towed. I mean, in Santa Monica if you are 1 minute late past the time on the sign you will get towed.

The cars are parked in designated spots on the road, with all sorts of rules about how long and how much you have to pay for the spot. In Santa Monica, pretty much every available parking spot has a meter that means you have to pay to park there, and are limited in how long you can park there.

Now, we can have all sorts of public policy debates about how much of a city's public space should be dedicated to parking spots, but at least the public had a say in the policy and at least there IS a policy.

We just need rules around where you can park the scooters and for how long, and how much you have to pay to use the public space to park your scooter.
Sounds like they're leaving trash at your door. Get an angle grinder and then dump it in the trash.
Their specific choices seem hard to replicate. Very strong friends, both very strong programmers, both willing to work at the same company. I'm sure that parts of their successes can be applied elsewhere, but from the article a lot of it is about having a strong relationship.

That sounds really interesting, could you expand on your work/research?
Yes, there are externalities, but perhaps the question to ask is, are the externalities of scooters less than those of cars when solving the last mile problem in transportation?

Cars and drivers, in my view, push MUCH more externalities onto everyone else (and let's not limit ourselves to thinking locally, all that CO2 we emit from driving disproportionately affects those in the third world and those yet unborn).
I put in my disclaimer out of sense of honesty. I'm a bike rider, I don't like cars either. As you can see however, my question is whether electric scooters with a three month lifespan can come out ahead in environmental savings.
Duality, for me, in the Catholic sense meant that there is "God" and then there is little old me. Non-duality is the realization that is available to all humans that we are not actually separate from the Tao, God, the Universe, or whatever label you care to place on the invisible power that governs the realm that we inhabit. You are an interconnected piece of life that through consciousness can impact future frames of life that are generated by the infinite universal computer that plays the movie in our mind. (Yes, you can come to have direct experience and knowledge that this power exists but it is a super-rational process that most of our left-brained peers, in our masculine, logic dominated society dismiss out of hand. This realization has been called Enlightenment, Awakening, Waking Up, etc)

Back to duality. We must remember that light and darkness are not opposites, they are the ends of a spectrum measuring the same thing: amount of light. Our western mindset has these placed as opposites, but they are not, they are the same thing. This is the principle of polarity in Hermeticism. The main insight is that these things are not different, they are the same thing in varying degrees (number of photons, in this case). Here is a decent overview (Look for Principle of Polarity, although the #1 point that the universe is a giant mind is the most important to me) https://medium.com/the-mission/the-hermetic-revival-7-ancien...

I'd highly recommend reading The Hermetica. It's not exactly an ancient source text, but it attempts to distill the wisdom of the body of knowledge called Hermeticism.

Your research is going to take you into works described as "occult". This bothered me at first, but then I realized it was my Catholic brainwashing about how occult is somehow related to satan or something. Occult simply means "hidden". These occult teachings, which every spiritual tradition possesses, are the pearls that were not to be cast before swine. This knowledge was typically reserved for initiates into a particular tradition. Basically, this means you had to be really committed and show your worth before you were taught this stuff. This is what many of the historical secret societies were protecting and teaching. This is what you learn when you reach the highest degrees of Freemasonry. Thankfully, the internet is blowing the lid off of this occulted information and people are waking up to the nature of reality at a great rate!

You are on a nondual Christian track reading the Gospel of Thomas. This Quora post sums it up nicely:

It can be more friendly for children when large platform "police themselves", but those efforts will naturally paint with very broad strokes.

I suspect the best strides here will be made by parental restrictions, so that the choices can be more individual and appropriate. (That's no panacea either of course; I'm merely suggesting it is the most promising solution.)

A 1x return on a large investment like these would not be good for a venture fund. They probably need to return 3x on the whole fund to get their carry/bonus, so a 3x return for a given investment is the bare minimum for success. They almost certainly would not have made these investments unless they believed they could make a return of >3x.
I'm inclined to agree with the general sentiment here—the fact that no one is willing to pay for software is harmful in the long run, because companies find other ways of extracting money, that either harm the product itself or the user.

But, asking users to "get together and offer to start paying money" in exchange that's free is completely unreasonable. Tumblr didn't offer any kind of payment avenue.
The logistics can be challenging, though, especially in an urban area. You need a place to keep and lock up your bike everywhere you go, and [for many people] a way to transport your bike on public transit.
Helmet laws for adults tend to reduce riders' willingness to use these services because they create inconvenience. In my opinion people should have the choice of whether or not to wear a helmet.

Personally, I usually wear a helmet, but if I happen to not have mine with me it won't stop me from taking a bike or scooter.

Having good situational awareness of surrounding cars, pedestrians, and other road users as well as stationary obstacles ahead of you provides much more safety than a helmet.
I think that depends on if there is enough tracable proof and if a case gets registered.
Why stop at comparisons to China? Parents have no problem doing this across Europe too, with both bikes and Vespa-style scooters.

I.e. to me, the problem is the US mentality towards car-minded transportation infrastructure, not the expectation of safety in a given culture.
In the realm of Christian theology (and perhaps other areas too), I think there's a related pitfall which is to assume that by reading the Bible exclusively, you can understand what the writers meant when they wrote it without confusing the issues with all the various modern debates about interpretation.

The problem with that is that many passages could have several interpretations, and by default the average Bible reader will tend interpret things the same way his/her parents or pastors or friend or favorite musician or the writers of The Simpsons interpreted them.

By trying to avoid modern bias, one ends up with whatever assumptions are so ingrained in popular culture that one wouldn't even think to question them.

One use of reading modern books (and not-so-modern books) about the Bible is that it's a way of being exposed to those other alternatives, so a Bible reader can make a conscious decision about what they think some passage means, rather than reading something between the lines that might or might not be there and not being aware that they're doing it.

I think CS Lewis's recommendation to alternate between new and old books is a good one.
"&array[0]" is equivalent to "&(array[0])" - [] has greater precedence than &. Desugared, this is "&(*(array + 0))" - add 0, dereference, then take the address.

In all sorts of surprising ways. For instance, research shows that soybean plants produce less defensive chemicals in higher CO2 atmospheres, which is a short term boon to certain leaf-eating insects, presumably at the expense of long-term sustainability of the plant, future generations of the leaf-eating insects after the plant's crash, competitor insects, etc.

Additionally, the emissions of that consolidated power plant can be better filtered (eg particulates) than the corresponding thousands of disparate engines.
My completely unscientific take is that its an unholy combination of deteriorating worker protections + social media addictions. So even though there are more avenues to connect with each other most people:

* rely on social media to try and satisfy their need for bonding with others
* just don't have as much free time as they did before, because they have to work harder/more jobs to stay afloat
Optimize behaviors, not outcomes.

You can directly control the actions you take, but not the results they lead to.

Because there's often luck/uncertainty involved, the results are often not even a good way to measure the quality of your decisions, sometimes good decisions can lead to bad outcomes and vice versa, be aware of this and notice when it happens.

Reward yourself based on taking the right action, use outcomes as analytics to learn from.

Confusing the two leads to anxiety, frustration, and beating yourself up over things you can't change.

Don't burn your mental energy on things outside of your circle of control, instead - try to spend all of it on taking actionable steps.
Even so, this is still a win.

1. Scooters use far less energy than larger vehicles.

2. Generating energy from fossil fuels can be done more efficiently at a power plant than in a small engine.

3. When power generation is centralized, it is easier to substitute it for better, more efficient forms in the future.

>The treasury sets a fixed interest rate and face value on treasury notes and then whoever pays the most gets the note.

Its important to point out that these are not market-based auctions. The Federal Reserve regularly steps in to purchase its own bonds (in effect skewing the price of the auction). The FED currently holds ~4 trillion worth of bonds purchased in prior auctions (its not currently increasing its holdings but it is repurchasing).

https://www.federalreserve.gov/monetarypolicy/bst_recenttren...

Central bank purchasing their own bonds can act to prop up the market, but also to disrupt market forces by keeping a "thumb on the scale". While this was initially done as an attempt to stimulate the markets after the crash of 2007/2008, it was never ceased, putting the whole financial system into real jeopardy when there is another crash and central banks have used up all of their bullets. This is a financial experiment with an uncertain end. The balance sheet of the BOJ as recently passed its annual GDP.

My scooter goes 35 miles on 12 cents of electricity.
Previously Amazon separated frontend focused engineers (WDE's) and software engineers (SDE's) but the former had a lower payscale than the latter. The end result, every single time, is that great FEE's would simply work at Amazon for 1-2 years and move to Google or Facebook where they were paid considerably more.

Amazon finally rectified it by introducing the FEE role, which has the same pay scale as SDE's. Perhaps more importantly, the WDE role terminated at WDE III and even that was incredibly difficult to achieve.
Doesn't sound like you grasp market economics as applied to rents in city centres.

I also think you are the handwavy one here with negative overtones. You underestimate the ability of people to actually adapt and to do jobs with a little bit of training. You, up on your fungible high horse also seem to assume that everyone does some expert job like what you do and obviously can't be replaced.

In computer science, we call this an "interface". Users can use energy without having to know it is generated, allowing the backend to be upgraded to a more efficient power source without users doing anything.

Also, the argument you're making here is called "the long tailpipe" and has been debunked – it's still a win even if the grid has dirty energy because of efficiency gains.
This is not the typical yield spread a practitioner or the fed would look at.

> he says the US debt will start becoming an issue soon

Which makes sense, but - I've been hearing this for couple of decades, and it doesn't seem to happen. I am not sure I understand why it doesn't happen and why people seem to care about the mountain of US debt much less than I think they should - but this looks like what is happening for a while. I still think this will become an issue sometime in the future, but I have no idea how one can predict how soon it would be.

> he seems fairly confident in China surpassing the US as the dominant global power in the near future

That depends a lot of what you mean by "dominant" and "near future", I guess. If you pick your criteria well enough, you could both claim China is already dominant (I mean, look at where all the stuff is manufactured! And their population numbers! And their GDP growth!) or that they are hopelessly behind (I mean, look at their GDP per capita - it's on part with Iraq! Nobody thinks Iraq is dominant... Or look at the immigration patterns - are a lot of people from other developed countries dream to go to China, or vice versa? How dominant can be the country where their own population rather live somewhere else?) So you could make either claim without too much effort.
Yes, rules, but probably not the same rules. Allocating space for scooter parking should be a lot easier than for cars, so fewer rules should be needed.
Yeah, there are unintended consequences with requiring helmets. Fewer people ride bikes, which means less exercise and more car usage. Affecting health and the environment.

Since the blog post does not have many code samples, this non-trivial AD example with Zygote.jl is worth sharing (it's from their readme):

julia> using Zygote
julia> fs = Dict("sin" => sin, "cos" => cos);
julia> derivative(x -> fs[readline()](x), 1.0)
cos
-0.8414709848078965
julia> -sin(1.0) # 'true' derivative in 1.0
-0.8414709848078965

So Zygote can apply AD to an anonymous function that looks up a function in a hash table from user input.

Amazon moves incredibly fast when it comes to products and incredibly slow when it comes to employee growth. They are treating it like a lightbulb moment, but several of the people involved in this have been working on it for a decade.

Reality is, they didn't want to pay FEE's big money because they weren't worth it, and now the company is starving for good UX and they want to pretend they invented a solution to the problem by creating a role that's existed at Google for more than 10 years.
Sidewalks aren't always wide enough to support foot traffic and parked scooters. I live in a residential part of a major city, with sidewalks designed a century ago, and a Bird (usually a cluster of them) is long enough to block 2/3 of the walking area.

One reason people might disagree is that you're pushing the externality of your own safety onto others. An example of an externality: those who don't wear helmets and crash are much more likely to have a brain injury (or death). This means that we all have to pay for your care now. In death (lack of taxes) or in financial damage. And in some cases like safety standards, people will also argue for emotional safety as well. Your death or injury could have a severe affect on those surrounding you even if you don't care but that's less measurable.

Freedom is complicated when you don't live in a silo.
Look up Mike Kaply's blog; he covers it extensively and, AFAIK, knows the topic as well as anyone.
I visited Sacramento from the Bay Area recently, and the Jump bikes were a revelation. It seems to me that electric-assist bikes are an easier sell safety-wise than scooters (bike lanes often already exist). I’m from Austin Tx and I really hope that the electric assist bikes see widespread adoption there, especially given the horrific traffic and historical resistance to public transit there (biking in the summer there is a hard sell, and it seems to me that electric assist could reduce the number of cars on the road)
Does anyone have any resources that explore how these groups achieve these things? (Especially the process of alienating inductees from friends and family--that's scary stuff.)

I think you already know this, but for the benefit of others who don't, the author addresses this, but gets it wrong:

>However, the number of miners cannot fall below a certain level, because without the miners providing the computing power to maintain the ledger, the bitcoin blockchain will not remain viable.

That's not actually correct. The difficulty of mining can drop to basically zero. The entire throughput of bitcoin as it stands today could be calculated on a single 2005 era cellphone if the difficulty dropped far enough, which it would if enough miners left the network.

Of course, if there was only one single 2005 era cellphone running, someone malicious could online /two/ 2005 era cellphones and then use their majority share of the network to start double-spending, so you do want enough compute power that it's not trivial for a single actor to beat it out.

There is an interesting lower threshold on mining difficulty that we haven't hit yet, and that's the point where GPU mining becomes viable again. There's quite a lot of small-time GPU rigs out there that have been mining some of the more interesting altcoins like monero and etherium that could switch over to bitcoin if enough asic miners leave the network.

So I'm not convinced on the authors "critical tipping point" thesis. There's a potential floor there he doesn't seem to be aware of.
Distinction without a difference. If you can't explain to your students why the words out of your mouth are useful, you've already lost them.

The fact of the matter is that you're getting hung up on implementation details that do nothing to explain the concept.

Pointer arithmetic, how pointers interact with the type system... those are important, but they're completely incidental. There's no fundamental reason C had to implement pointers that way. They're factoids about how pointers work in C, practical mechanics. They tell you nothing about what pointers are in essence: a memory address.

And I don't know if you've worked with novice programmers lately, but it seems pretty obvious to me - based on how so many people get their heads discombobulated about pointers - that that conceptual clarity is needed. The details you're listing don't need to be in the first sentence.
"Israel uses deadly force against civilians [they think might be] engaged in acts of force against Israel" would be closer to the truth. Missiles doesn't check if everyone near are bad guys before exploding.
