Hi Jash!

I focus my work on technical research directions I believe increase the probability of advances in AI being outstanding for all of humanity. I'm fortunate that Google provides me resources to do so, with broad autonomy to work on what I think is important.

My main focus is on building techniques that allow humans to understand how neural networks make decisions, because I think that will be a powerful tool in making sure increasingly automated systems are aligned with society's values -- for example, being fair -- and are making decisions for reasons we endorse. I also spend a lot of time thinking about accident risk and safety. I believe this work is robustly good for the world.

Of course, lots of concerns about AI can't be addressed by the kind of technical research I work on. I think technical research into interpretability, robustness, safety, fairness, etc... is necessary but not sufficient for the kind of world we want to see. There are also tough questions of public policy, international governance, and scientific ethics -- such as issues around the abuse of AI systems. On these kind of issues, I'd largely defer to people who think deeply about these topics, like Allan Dafoe (Oxford), Michael Page (OpenAI), and Tim Hwang (Ethics & Governance of AI Fund).
That 2% figure seems high. I know transaction costs in cryptocurrencies tend to be high by financial standards. Maybe that accounts for it.

Also maybe by being one of the first to offer such a thing, they can charge higher management fees.

When people refer to the military industrial complex, they are referring to the businesses like Lockheed Martin, Raytheon, etc. that are the private companies involved in designing and building weapons.
But what would you do if you wanted to be fast fashionable? Presumably you either don't care about fashion, or only wear 'timeless' pieces, which while they don't go out of style, don't set you apart with your fashion choices.

For someone unknown definition of “balancing.” (Rebalancing and re-weighting or re-constituting are different things.)
We might just find out the things we thought are worth it, are not really.

Then give a concrete quantification of that. It's a very complex question. Entire careers have been built on how to price something complex. That's called "economics."

Amazon Web Services (AWS) | Software Development Engineer | ONSITE (relocation) | Seattle, WA | Full Time

AWS Mobile is dedicated to helping builders of mobile applications leverage AWS to build and scale their applications. We've built tools for iOS, Android, and React Native developers that help them provision AWS services, build their application logic, and test on real devices. Our goal is to bring the same level of software development automation to mobile developers that web developers have had for years.

We work closely with our customers to understand their needs and dive deep on the mobile platforms and their unique build environments, SDKs, etc. to understand how we can best serve our customers. This is a really exciting and competitive space and new technologies like React Native are making it even more interesting.

This position is not an entry level SDE position and we're looking for people with 4 or more years of experience.

I'm the hiring manager for this position so please feel free to reach out with any questions. If you're interested, my email is rrcb@amazon.com or you can checkout the job posting directly here: https://www.amazon.jobs/en/jobs/619875/
This is really interesting. It would be amazing if it could be run from the repository side rather than from a single local machine only. ie Instead of running on my personal dev machine over all of my local repositories looking for changes that I forgot to commit or stash, it could be run from github to all machines that had copies of the repo. Result: a prompt reminder to commit (on the github server machine) of all remote machines work. The use case is that of a project manager looking for uncommitted work from software dev teams.

A further application of this tool would be to create automated backups of every branch of a repo on every development machine. The use case is again from project management: periodic backups for safety or a backup of everything if there is a contract dispute or one consulting team's contract is ending and a new one is starting.
This is a ton of value for all companies that do software to have this tool expanded to cover both of these use cases. You could definitely found a startup to sell this service to any company that develops software.

I am surprised that this is news. Google has done US government work for a long time. After 9/11 the newly formed homeland security wanted pictures and accurate data in regards to residential addresses in the US. At first they went to the credit bureaus and data brokers to collect and store this information due to the fact they already had researchers on the ground collecting data. Google came along with Google earth and not long after that Google street view. Think about how long it was before they where able to actually monetize google earth & maps. They perfected the art of geodata collection and was likely paid for via government grants [0] and contracts. Even today they sell access to different government agencies[1].

By the proposed methodology, if I sold stocks and paid off my mortgage, I'd thereby become poorer and if I did a max cash-out refinance, blew half of it Vegas and bought stocks with the other half of that money, I'd become richer.

That seems like a flaw in the methodology to me.

a reason they can't price match is that their prices are already at razor thin margin, since their economy of scale doesn't kick in like the big co's.

That still leaves $99,563M. I'm not familiar enough with the details of the defense budget, but when looking at budgets, in general, the focus should be on line items that move the needle significantly.
That's where we're headed, I agree. But I do believe that the degree of equity has been exaggerated. Spend much time in Central America, for example, and the gulf between classes is obvious. In the US it's far less so. Partly it's pretense. But it's also geographical segregation. It's really in your face, in parts of Manhattan.
I feel like I'm being trolled, but the answer is yes, yes, yes, and yes, because I, a progressive, don't give a shit what people do with their lives.

I, a progressive, value personal freedom and want society to support that.

What choices people make with their one shot on earth is up to them. If a handful make choices I don't agree with, I don't give a shit--they're still people are as deserving of the social safety net as anyone.

And that's what it comes down to. I don't care if people make choices I don't agree with. It's their choice, their body, their whatever. Society should work for them as much as it does me, or it's a shitty society.
If you want to "confidently accept deliverable email addresses" the only solution is to send a test message out with a link that the recipient has to visit to validate that the email address exists. Otherwise what about regex and email valid addresses that still don't exist?
No, they're just choosing where they decide sustainable such that it doesn't strictly require every body in the supply chain earning at least (ppp adjusted) poverty wages.

I don't mean this as like a nihilistic "buy anything because it's all awful" sort of thing it's just that we live in an inescapably mutual world so there is basically no direct line or direct chain from the base inputs to the consumer outputs and somewhere in that tree is a leaf that is terrible. We can choose the best that we can but there is no perfect and its a stretch to even claim there's a good.

this is the how capitalism kills us all. we cannot be ethical and so every day we betray our ethics until we begin to betray them as a matter of course instead of a matter of necessity.
The transaction costs would probably add up to more than 2% depending on how accurately you wanted to track the index, plus it sounds like a bunch of work.

Charles Schwab, which is relatively high, charges $8/trade (for unmanaged trades).
Having worked in the supply chain for companies producing fashion clothing for popular western brands, it is eye opening and terriying the amount of work/energy/inputs which goes into making clothes.

To give a denim example:

Cotton growing wrecks the land, farmers gets peanuts.

I'll give a pass on the actual fabric making and sewing process, but what really got me was the amount of energy and robots used to destroy denim to make "distressed" jeans.

In some processes you have many hours of fabric being distressed, in wheels, in drums filled with different types of pebbles, giant presses, even lasers to slice them up... the jeans spent more energy and way more time getting ready for fashion then they did getting produced. (not considering cotton growing time).

All this work to produce something which lasts a lot less then it could, and probably will get thrown away soon. Clothes need an environmental impact label.

I have a new found respect for man-made fibres like polyester, polypropylene etc as producing those fibres is so much cleaner than natural goods, and instead of having to spend a lot of energy getting the fabric to "feel" right, you just modify the properties of the fibre by changing how its produced.

Edit: Fashion is one of the few remaining industries where obsolutely zero consideration is given to environmental impact when designing and producing clothes. This isn't just a poor country thing where they make clothes in a enviornmentally destructive way, the design of the clothes involves IMHO a lot of un-necessary production steps for an extra minuscle percentage of improvements.

Other industries, like say car parts, think about things like the energy inputs to their production process from the design state onwards, fashion doesn't. Even in sevice industries like making web apps, people think about inputs, and design to use as few of them as possible.

Isn't that inflation adjusted pretty much a normal price for a down jacket 30 years ago? Something that you'd buy once every 3-4 years or so? At least that's how I'm still treating this. Also, I'm Swiss, so my sense of pricing may be off here. But winter shoes and winter jackets for us is something expensive that one doesn't buy often.
It is worth noting that I think Survivor treats their cast very differently. It is hard to know exactly, as I have never seen directly, but I have spent time with the crew from Survivor, and spent some time on location while they were shooting. They treated me with amazing grace and I am forever grateful for their time and hospitality. I imagine that their record may not be perfect, but I think their approach to this is more like a sport with athlete, than a prison guard in the Stanford Prison Experiment.

The length of the repeated part is the multiplicative order of 10 mod q [1].

Look at the Wikipedia page on repeated decimals and you can see many of the repeated sequences have length (q-1) ((q-1) is phi(q) when q is prime) [2].

There's a SO answer that talks about this [3]. I think I can derive it here, though take it with a grain of salt as I might have screwed something up.

Say you have a rational number p / q, and w.l.o.g., p < q. Consider an integer, R, that corresponds to the repeated portion of the rational number (in base 10), with length s (in decimal). This implies:

p/q = R sum_{k=1}^{\infty} 10^{-s k} = R / ( 10^s - 1 )

rearranging terms:

p (10^s - 1) - q R = 0

Let's just assume for now 10 and q are relatively prime. I think I have to do a little hand waiving at this point and just assume the above has a solution. If the above is true, this means 10^s = 1 (%q) for s equal to the order of 10 mod q, which is a fancy way of saying 10^s = C q + 1 for some integer C. One choice that will always work is taking s = phi(q) though this might be smaller (specifically a divisor or phi(q)) depending on what the order of 10 is to q.

So to make the above equation true, let's be coarse and choose s = phi(q) in the below:

.. p (10^{ phi(q) } - 1 ) - q R = 0
-> p ( C q ) - q R = 0
-> q ( p C - R ) = 0

And there you go. Assuming that I haven't bungled anything, this also gives an 'algorithm' to find the actual repeated sequence: R = p C = p 10^{phi(q)} . Choosing s, the length of R in base 10, to be phi(q) will always "work", but, again, s might be able to be chosen smaller, depending on what divisors of phi(q) there are and what order 10 is to q, so the real answer of the length of the repeated sequence is 10's order in the multiplicative group mod q.

There's also the case of when 10 and q aren't relatively prime that needs to be worked out.

You can also see how this argument could be modified to work with other bases.

When you're investing you usually become suspicious of 300% per year returns. Yet that's what this fund would have returned over the last three years if it had been available since the start of the graph. Using a log scale makes it look sane in comparison.
2% annual management fee is peanuts for coinbase. Thats not how they are going to make their money on this.

Its clearly is about market information. If they were to capture enough funds in the index, they can straight up manipulate the market to choose the coin they want to release: they can charge whatever they want for the next coin release upfront, no cost to them or to the coin seller.
