This is pretty cool, I wasn’t aware of these types of challenges. How does one even approach this?

Feels to me like it’s similar to dumping a binary with an image, the format being entirely custom.

And/or trying to decode a language or cipher, trying to recognize patterns.

TFA details a solution, it's pretty interesting. Basically the problem was to reverse engineer an absurdly obfuscated and slightly defect MD5 algorithm.
davedx•48m ago
What does it do - front run crypto investors or pump and dumps?
wittyusername•37m ago
All I think when I see this is "this intelligence wasted on finance and ads."

Can you imagine human potential if it was somehow applied to crop harvesting efficiency, new medicines, etc?

Not everything has to be perfectly efficient but it just saddens me to see all these great minds doing what, adversarially harvesting margin from the works of others?

0x3f•33m ago
We don't have any reliable and scalable way of doing this allocation, though, so it's a bit like saying that all the resources are wasted being locked up in asteroids.
blitzar•28m ago
Silicon valley had the chance - dont be evil, for humanity, not like those Finance Bros.

At this point tech is probably worse than finance, at least in finance they dont pretend to be saving the world no matter what the giant squid says.

paulluuk•27m ago
Don't we already harvest more food than humans could ever eat, and have a huge pharmaceutical industry? I get what you're saying but these two examples seem counterproductive imho.

Which begs the question: what would actually be a good field to apply human potential towards? I agree that finance, sales and ads are very low on that list.

ViscountPenguin•11m ago
I would imagine that increasing crop yields would do social good primarily via decreasing the amount of cultivated farm land, especially since we're well past Jevons paradox territory with calorie intake I imagine.

While the pharmaceutical industry is large, the marginal researcher does still seem to have a pretty positive impact from an outside view.

The most positive use of human time probably looks something like antiwar advocacy, but I don't really think that most quants have the social skills for that tbh.

>Can you imagine human potential if it was somehow applied to crop harvesting efficiency, new medicines, etc?

How is finance not exactly that?

Isn't Jane Street mostly into HFT arbitrage?
JasonADrury•9m ago
You need market makers like Jane Street to have well functioning markets.

The markets have shown themselves to be an excellent way of applying human potential to things like crop harvesting efficiency, new medicines.

ViscountPenguin•17m ago
As someone who has worked in the industry, I've yet to see any compelling argument that high frequency quants are making any meaningful contribution to society. Maybe on the low frequency end, but slightly higher market liquidity doesn't serve that large a social good imo.
JasonADrury•12m ago
High frequency quants almost certainly don't directly provide a massive social good, but they're one of the many facilitators enabling the smooth functioning of markets that do.

But FWIW, the comment I was replying didn't seem to be specifically critical of high frequency quants. Dismissing the entire field as something that doesn't contribute to society is beyond absurd.

ViscountPenguin•3m ago
The context of the comment being a Jane Street blog post is why I singled out HFT.

I think we're probably roughly in alignment w.r.t. other forms of finance, but the market liquidity gained by a marginal HFT employee almost certainly isn't worth the marginal cost imo. Even in finance, you could do a lot better by expending that human capital into optimising the structure of the markets themselves (there's lots of research on how hideously inefficient the TSE is because of its coarse tick sizes, for example; but vested interests get in the way of fixing that).

zeroCalories•20m ago
It's not wasted. Society can pay for the talent it wants, and they don't want to pay for this. Instead this talent helps to grow the overall wealth on in the world, letting us pay for the stuff we want.
azan_•18m ago
There are much much more great minds working on new medicines than on HFT. Also HFT is good, it makes world better place!
