HFTs are not hedgefunds and generally are marketmakers.

Yes exactly it proves their "monopoly" and will invite antitrust actions in near future. So few individuals shouldn't wield so much power particularly given that they aren't elected even if in this instance they may be c

Which makes me wonder is there a statically typed prolog like language out there?

Unfortunately that's only on paper due to LLVM issues.

That's a great way to put it. BTW if you are quoting someone else, would love to know the source.

All pure functions are idempotent but not all idempotent functions are pure. It has nothing to do with the domain/range of the function.

Haha entire evolution has been all about "cashing on genetics". As a society our aim should be to let people of a wide variety of genetics, cash in on their respective "lottery" instead of arbitrarily drawing lines at in

Complications around sex purely for pleasure might have a lot to with STDs and may be some historical cultural baggage than bonding and intimacy issues.

If you're consistently wrong there's alpha even in that, just doing the opposite would work wonders.

But our industry has all kinds of perverse incentives to do resumé driven development. How does one get to put paxos on their resumé if they built the correct simple solution?

I see so the extra kernel IO thread which can be spin waiting is one extra busy core and latency of getting data from one core to the other is the additional overhead.

Do you suspect account deletion captchas are harder than account creation ones?

I am not sure how user stack tcp or DPDK would get around the power consumption issues of kernel polling. Infact the usage I am aware of pretty much involve polling in user mode because any context switch or O/S scheduling related over

by hawk_ 6y ago
One thing that I haven't been able to get is if this makes things like DPDK or user mode tcp stack unnecessary since the system call overhead is gone.

I am afraid tier 1 banks aren't tier 1 in HFT though. Best HFTs are at "small" houses and your tier 1 bank experience isn't reflective of what they do.

That's right. Java libraries even within JDK are notorious for unnecessary allocations and locks (which also do allocations for queues) putting GC pressure. C-like java means the need to roll out your own or using libraries like Chroni

Unfortunately the bureaucrats still go through dated curriculum to get where they are and there no incentives to keep up with the times, technology or otherwise. These same people decide on the criteria for the incoming class and the viciou

You're right there no x86 emitting going on here, so not relevant.

by hawk_ 6y ago
Edit: as had been pointed out here there is no x86 code generation happening so this doesn't apply. Yes I have seen claims from people along the lines of 'x86 code has more optimization paths in mainstream compilers for historic a

Italians can understand Spanish quite well and vice versa. Similar for Portuguese. That doesn't make them dialects of Latin.

Which version of Java are you using? And what is Rnd? The class included with JDK is Random. We rely on escape analysis to elide such object creation for us and it works reasonably well. If something this trivial doesn't work for you,

Yes I'd very much like to know if there's a JDK or rust unikernel someone has used in production - commercial or open source.

i am into that kind of thing :-) if i wanted to try this kind of stuff at home, i.e. buying any necessary hardware myself, how much do you reckon the whole setup would cost? any suggestions on used NICs/switches to try this with?
