So what happens if you’re running late one day? You don’t get to go into work? Or do you hold up the plane?

One of the best interview experiences I had was with a firm where nearly everyone participates in the hiring process. I don’t know any details beyond what I experienced as a candidate, but they interview tons of people, and everyone wh

Wouldn’t the ‘valid’ values in such a table be relatively sparse, creating a high likelihood of cache misses? The guy’s agonizing over 4 cycles, but a cache miss is far more costly.

I work on a market making team at a major investment bank, and I can back this up. There is a very clear and serious separation between those who trade bank funds and those who trade client funds. We are not allowed to know anything about

I very much approve of the 'idea' of WikiLeaks. I am not particularly fond of WikiLeaks as an organization. I don't like the way they hold on to material until they think it will make the biggest impact. It makes me wonder

Java is interesting in that variance is defined at a reference site. Contrast that to, say, C#, where variance is defined at a type's declaration site. In C#, a type `Function<in T, out R>` is always contravariant with `T` and c

Whoops, brain fart: that should have been 45%. But yes, I work in finance. It's definitely not unheard of for bonuses of top engineers to reach multiples of their base salary. I'm not aware of compensation being that lopsided wh

In NYC, and in the financial sector in particular, total total compensation often includes cash bonuses, while stock components are less common compared to S.V. Without insight into total compensation, these numbers are only minimally usefu

Seems a rather glaring omission—as a software engineer in NYC, roughly 55% of my total annual compensation comes in the form of a cash bonus. Since total compensation tends to vary more significantly than base salary, I would continue showi

Not only did they leave old code in the system, but they made changes to it without reviewing whether the old code would still work correctly, despite still being callable: In 2003, Knight ceased using the Power Peg functionality. In 2005,

Probably, but some critical errors like stack overflow or out of memory could prevent the stack from unwinding gracefully or otherwise prevent the accumulated log from being written. And then you’d have nothing.

There's really only one kind of environment where open offices make sense, and that's if you're in a high-stakes production environment. The classic example is the trading floor: everyone on the team works in the same room b

I don't mind a proper em dash (w/ width equal to full height of the font), which is what the original headline had. Somehow it got changed to an en dash in the HN headline, which has only half that width. Unfortunately, there are

by BonesJustice 8y ago
Yeah, my pre-coffee brain definitely did not parse that headline correctly. The HN headline is pretty faithful to the original article's, but the article's headline is poorly worded.

If I’m ever willing to make the time, I think I’ll complain to Netflix about this while framing it as an accessibility problem . They must know by now how many people hate this, but they refuse to let users disable it. If you CC their gen

I hear this argument a lot. Obviously, the perpetrator would prefer that the video spread widely and inspire similar acts of violence. But that is not the only possible outcome of allowing the video to spread and be seen. Humans are lar

I tend to agree. That said, I rather like V’s short primitive type names (i32, u32, f32, f64, etc.). But why do definitions put the type _after_ the field/variable name? So many of your type names are the same length! Think of the b

NLP is a possibility, but bear in mind that HFT is all about optimization. The confidence levels desired can vary significantly based on what you intend to do with the information. Acting on M&A news by taking a more aggressive positio

by BonesJustice 8y ago
There’s two sides to it: you might decide to take a more aggressive position, but you might also use the headlines as a signal to back off (and stop or scale back trading of securities for the affected underlying, at least temporarily).

I can confirm first-hand that this is a real thing, and that if there’s significant movement immediately following a headline, you likely won’t end up with more than table crumbs if you’re not one of the first two or three players to respon

The only kind of HFT I’m directly familiar with is for automated market making, so I’ll speak to that. Market making in itself provides a valuable service by keeping spreads razor thin and ensuring there’s enough liquidity to satisfy almost

There’s also more straightforward reasons to want a microwave connection from NYC to Chicago. Say you want to trade off news signals: you want to relay the headlines (from Bloomberg, DJ, etc.) to your colo sites as quickly as possible.

Not just when doing something non-obvious, but also when not doing something that might normally be expected. “We don’t need to synchronize here because <some invariant>” and whatnot. Basically, whenever a casual observer might thin

It wouldn’t disintegrate due to a sonic boom, because this extraordinary speed is due to the plane being helped along by tailwinds. If the tailwinds disappear, the plane slows down; it doesn’t speed up. What I’m not clear on is, would the

I’m a bit under the weather, so my comprehension may be lacking, but I think you’ve got your signs reversed (or your head/tail terminology flipped). If tail wind (moving with the plane) were negative, then air speed would exceed grou

Exactly. And Apple makes it easy when it comes to cancellation too: go to my Subscriptions screen, select the service, and click ‘cancel’. It doesn’t matter who provides the service—it’s always quick and easy. Granted, Netflix has always

It probably takes at least a week or two using another IDE to really get a feel for its strengths. An hour is definitely not enough time to spend with IntelliJ. But use it for a couple weeks, and you’ll wonder why you ever used anything el
