Presumably, the greater the time period between auctions, the more risk there is for market makers, and therefore the greater cost to customers. I'm sure there's a sweet spot that is less than once per day, and greater than conti

>If we arbitrarily limited transactions to human speed would there be some kind of systemwide downside? It's worth asking what that artificial limitation would actually be, and how it would result in changing the game for market mak

Can anyone in the industry comment on whether this kind of strategy really exists? Surely any automated, news-based strategy's bottleneck is not due to sub-microsecond latencies stemming from microwave tower placement. I've alwa

He’s wrong about Bitcoin? Not a lot of evidence to support that theory at the moment.

I'm of the mind that the usefulness of event sourcing as an architecture is directly correlated with how easy it is to determine what an event is. I'm also of the mind that most challenges with event sourcing are ultimately toolin

Trust generally isn’t by default, it is built. I’m not sure there’s anything wrong with that.

I will admit that these things are slightly easier Kubernetes, my original point was mostly just to say that Kubernetes itself doesn't really provide any of these things in meaningful ways - you just described a bunch of separate, nont

Ten years? Do you really think software development as we know it will be gone in ten years? I think it’s important on hacker news that we have perspective on our place in society and history and that we don’t think of ourselves (speaking f

Yeah - that’s far from batteries included though, and comes with many limitations, especially for non-12-factor apps. It also doesn’t begin to answer questions about what that log store is, or how to alert on the contents of logs.

We are. I guess I wouldn’t consider that enough for our purposes. Actually retaining and alerting on logs, or alerting on anything for that matter is not out of the box unless I’m missing something.

I very much agree that kubernetes is useful in an environment that doesn’t need to scale, but do tell how it enables consolidated logging and monitoring, since my medium/small shop is spending quite some time setting up our own infrast

My guess is that it’ll be like google in NYC. Quite substantial, but obviously no Mountain View.

With good tooling, it is arguably a lot easier to understand than a synchronous microservices architecture, because of the persistence of events. I’ll admit it’s probably harder to debug than a monolith, but that’s true of any distributed s

ETFs may be associated with passive investing, but there is passive investing without ETFs, and active investing using ETFs.

That’s not much of an answer. If anything, it seems to me like Oracle is seeding more control to the community. I could be wrong though, I don’t follow this stuff as close as some.

This is a classic warmup for an ensemble of actors in a play. We used to do it with our eyes closed as well.

I wish I could find a link that was just about the data and not Lebron’s reaction to it, but my interpretation of Lebron’s slowness is that he has the same skill. https://www.google.com/amp/s/amp.usatoday.com/

For sure, just putting out the data so people can add their own assumptions. Personally I’m quite the skeptic.

It’s not entirely true that robinhood doesn’t make money on transactions, given that they receive payment for order flow.

It wouldn't be immediate, but the second you put on a trade with any kind of size that far out of the money, the market makers will wise up.

An interesting thought, but in practice, trading derivatives affects the value of the underlying pretty strongly. Whoever is selling you those puts is selling bitcoin (or futures) to hedge, which would drive the price down as you try to put

Not as easy as application code, but easy enough with a good migration tool.
