Options spread.


What’s heartbreaking is that he didn’t trade any leverage at all. He executed an options spread that was worth about $700k on each leg. Due to the nature of buying and selling options, the app showed his position as short $700k because the long leg hadn’t settled yet. All he needed to do was wait and he would have seen the balance go back to what he expected.


The floating point results are suspiciously good compared to the rest of the results. I wonder if they have some good VLIW instructions for floating point or it’s just an error in the spreadsheet.


VLIWs tend to do well for programs with predictable-at-compile-time memory access patterns which tends to correlate with floating point heavy code.


Linpack is a floating-point benchmark focused on linear algebra operations. Coremark has some floating-point-heavy benchmarks in its suite, although a common criticism is that the footprint is too small to exercise the memory system.

So yeah, the "Maximum MFLOPS" row looks suspicious.


This doesn’t have any info about the instruction set.



Detailed description of instruction set is secret. You can't even download sources for the patched Linux kernel without signing strict NDA.


Instruction set documentation was released a few days ago: http://elbrus.ru/efficient_elbrus_programming_book_2020-05


In fact you can't use this manual to create compiler for Elbrus. It looks like you still have to be russian citizen with signed NDA to get all required documentation.



Indeed, thanks!


If you already know what a vector space is and what a tensor product is and you recognise and understand bra-ket notation I would say there’s a very good chance you already know what quantum entanglement is.

So who is the target audience for this?


It may be true that bitcoin will be a good store of value but this article doesn’t make a good case for it. For example, bitcoin is quite volatile, which would tend to make it a poor store of value. The article doesn’t address that aspect at all. If obvious drawbacks aren’t addressed then the case isn’t made.


I once had my card skimmed while I was overseas. Westpac reversed all the transactions and sent me a new card.


That was good on their part.
