Since this question always comes up, I'll aggregate: - Payment for order flow - Interest on idle cash - Robinhood Gold, a subscription model with side benefits, the most notable of which is... - Margin lending It's unclear whet

This would imply Robinhood is itself is a market maker, which is not true.

This is mostly correct except for the last sentence, for any conventional definition of "clearer." You could replace "clearer" with "market maker" to be more correct, but it is important to note that the marke

Even though you never hear the counterpoint on HN, it’s important to remember that FB’s behaviors are not necessarily objectively bad - people can have different views on these things.

Can you expand on that last sentence? Not that I’d disagree, I’m just curious about what specifically you’re referring to. My team is currently underwater supporting a decades old system of batch ETL, where it’s a major challenge to underst

Is anyone out there doing (or considering) streaming ETL as opposed to batch?

I think the problem is fairly well defined, the headline just doesn’t define it fully (with good reason).

While this is mostly true, it’s important to understand that rents are not just “cost + profit.” They are market based. Sure, the market often pushes it towards something close to that formula, but it is not a guarantee, and many of the sub

What does blockchain provide for those use cases over a simpler distributed database?

I agree on the diff viewer. Check out Upsource for code reviews. It's pretty much exactly what you would expect from a JetBrains-built code review tool.

I don’t mean to be overly negative, but I hope you recognize the irony in describing your image of a hacker as someone with long, grey hair, and proceeding to say that superficial traits like appearance don’t matter, only ideas.

And it seems very plausible. I’m sure a HN reader is worth far more than $7.47 a year to Facebook.

Martin Fowler does a pretty good job of categorizing some specifics around the vague meaning of “event driven”: https://martinfowler.com/articles/201701-event-driven.html

Completely agreed. This was an enjoyable experience for me, even on a phone. And it didn’t seem to come at the cost of journalistic quality.

That’s a good point, but it does feel like a poor analogy to me. Obviously nuclear war is not as inevitable as thanksgiving.

For what it’s worth, since no one is taking the other side, my first impression is pretty good (though I’m on mobile). Obviously it is extremely bold, to the point that it’s almost more art than it is design, but I like it, cause why not.

When the standard of “well” is Google, who has very much data indeed, that’s not a farfetched premise.

Another way to think about it is whether the IDE can do it for you. As a Java dev (who is admittedly a bit of a slave to IntelliJ) this is a huge part of my programming experience.

The whole “never use floats as money” thing is a little overblown. If you need exact values, where everything needs to add up in the end, sure. But if you’re generating the value yourself it doesn’t really need to be precise. For example -

Why are you so sure that upgradability is a requirement for a pro machine? I’m asking genuinely, not because I’m a “pro,” but because I’ve read annecdotes of people who use Macs professionally but do not feel the need to upgrade their inter

Sorry yeah, I didn’t mean there isn’t a lot of software that qualifies as HFT, but the very quickest seems pretty light on software.

by pgwhalen 9y ago
Good source. I’m in the industry but not at an HFT, so my comment is more of a well-informed guess.
623.
by pgwhalen 9y ago
There is barely any software in the hot path of competitive equity HFTs these days. Even the most finely tuned C++ is probably on the order of single digit micros tick to trade, but the goal is sub-micro.

I get the frustration of the author on grandfathering in mortgages for interest deduction, and you could certainly argue it’s for the benefit of boomers at the expense of millennials, but isn’t it the only sane option? Otherwise the tax bil

Ah I see what you mean, that makes sense. I took quickly jumped to assuming ignorance regarding the Libor thing. I definitely agree with the concept. This reminds me of potential VIX options manipulation. Not quite the same thing, and pro

It seems you misunderstand both derivatives as well as the Libor rigging. The price of a future absolutely can affect the price of its underlying, and the Libor rigging has nothing to do with any of this - the problem was that the value was

This is ignoring the fact that autocorrect can fix massively incorrect words. If you’re off by half a centimeter for a while word it could be complete gibberish if not for autocorrect.
