This is a really cool finding, but also really sad considering all of the animals from before are now extinct. Hope future grassland and forest protection programs take this history into account!

And not tesla, seriously?

Very fun to see how trends got started! Searched quantum computing and the oldest result was Peter Schor's paper on what would become Schors algorithm

Adamatzky is a GOAT in biocomputing. Hes the sort of researcher who really makes me question why we spend so much money on developing quantum computers and other new ways of modeling biosystems when using other biosystems as analogs seems far cheaper and more fruitful.

I'd be very very worried about a protein model that just came out alphafold to be used to come up with drug targets without at least some molecular dynamics simulation of the solution within which that protein works with. There may be other glycans, ligands, or wholly different metabollites that could affect this binding.

"In 2018, I wrote in the Washington Post that startups have begun usurping the responsibilities of governments at breathtaking pace. Whether it was Uber and Lyft supplementing much of public transport in major cities or Palantir assisting in the important work of the U.S. intelligence community, it is becoming clear that government cannot meet the needs of its citizens without the tech sector’s aid. " This doesn't seem quite accurate.

You'd have thought that that Quorum blockchain would prevent such things..

"Not only that, but the decentralised utopia that Nakamoto dreamed about, namely avoiding trusted third parties, is still far out of reach. Ironically, there are now three mining pools – a type of company that builds rooms full of servers in Alaska and other locations way up above the Arctic circle – which are responsible for more than half of all the new bitcoin (and also for checking payment requests). " don't think that's quite right..

Right okay makes sense...guess I am just too used to NISQ and having to run many thousands of shots for high enough fidelity..if all you wanted was one output, then yeah one classical string is easy enough, thanks

Right, but you would still get the basis states for all 127 qubits right? And that would be 2^127 output states. Yes, you could do some sort of search maybe to find highest probability outputs only, but if you needed every output value for a follow up algorithmic step (like in VQE for ground state prep wherein you keep using previous results to adjust the wavefunctions until ground is reached), then wouldn't it be a bit tough to use?

Also another problem: you now have 2^127 output values leaving the quantum processor. If you're using a hybrid quantum algorithm that requires classical processing as well (which are most algos used today), you'd need more than a yottabyte of RAM. We can get around this problem by storing all 2^127 pieces of output data into other data types that compress the total size, but if you genuinely are trying to use all 2^127 outputs, you'd still need to do some pretty intensive searching to even find meaningful outputs. I guess this is where Grovers search could come really handy, right?

Maybe you just havent been seeing the same horror I've been seeing in terms of whole families getting covid and falling quite sick in India due to the shock it caused to the healthcare system..

I just want everyone here to know that Sequoia is funded by university endowments, and yet still does not have the confidence to invest in bleeding edge technology, picking instead to invest largely in "moat oriented" software. Nothing overtly wrong with it, but I just don't trust them when they claim to finally care more about slower growth companies.

As someone who was an avid swift developer, I can see how people can get attracted to building OSS for .NET or Swift, and how it might even be necessary in many cases given the lack of feature update by the companies. But, after leaving the world, I just really hope more devs see that they aren't valued by these companies for building such open source, and in continuing to validate their products through continued fixes, we are only making them stronger. Maybe I have a very pessimistic view, but I've started looking very literally at how companies make money from any open source work they do before using it so I know what they want of me in the future and to see if I support their business model or not. Its for this reason I picked using Singularity over Docker because I just know that a federal lab + contractors for scientific work will actually stress test and continue paying for the software while docker, who ultimately doesn't then a profit yet, may either get bought by one of the FAANG+ or have to start aggressively curtailing access.

If they wanted African supply of an mRNA vaccine, why didn't they just use The Odin's completely open recipe https://www.bloomberg.com/news/articles/2020-06-25/one-bioha..., which was based on the Moderna vaccine. But, why would they want such a vaccine in Africa in the first place? The storage would be impossible anywhere outside of really rich medical facilities, and even that is not necessarily feasible. Why not go with funding vaccines by HDT bio, which have made mRNA vaccines but with metal particles in the outer lipid layer to allow for storage at fridge temps https://pipelinereview.com/index.php/2020090175739/Vaccines/... or something else?

Thanks, how does this compare for matrix multiplication and logistical regression to other machine learning specific cores though, like a GPU or one of those Google Tensor Cores? These Alibaba chips don't seem like they'd do very well at those tasks, but are just great all purpose CPUs

I feel so bad for Sophie Zhang. Not only did she risk her job to whistleblow, but she had the limelight totally stolen from her by Frances, even though she said many of the same things already months prior. And it wasn't Frances' fault, but rather the big three media companies in the US who didn't really bother to cover Sophie's work, and then follow on publications like this one referring to Sophie as "the other".

To respond to the title: yes, yes they are, if you consider how many live in infura or an AWS geth instance and/or quorum by JPM. Doesn't mean its not a better means for data security...just that yes, the publisher of said smart contract can just replace or change to contract if they really wanted to if it were not part of the mainnet. There are many infura nodes though that are part of the mainnet, so that's unlikely unless some company just forced all users to their own ETH network.

I think that's their whole business model really, a beautiful skin and api on top of a very boring process that makes developers want to use it. Stripe itself doesn't really handle a lot of the banking work and uses Evolve Bank (like basically every fintech company in America) and Goldman Sachs to actually do that work https://stripe.com/treasury. Not saying that itself doesn't take a long time to develop in terms of relationships, but its obviously much faster than actually going to FINRA and the US Comptroller and making a new bank.
