Note, me & every other person I knew in the industry were extremely disappointed with Flash Boys. It was a submarine ad for IEX & got things just plain wrong.

Feel free to read it but remember that IEX & Brad Katsuyama work on behalf of one set of market participants that are decidedly against the interests of other market participants such as retail traders.

Figuring out how to disable that damn thing was my top priority when I had a thinkpad. Maybe I should have stuck with it, but it was just an annoying thing that was impossible to control and easily knocked to where I didn't want it to be (a problem when input focus is mouse based rather than foreground app based).

So this looks interesting to me... but possibly suffers from the same problem of inadvertent activation.

What is "wasteful" about HFT and how would it be reduced with smaller tick sizes? It seems like there would need to be considerably more order activity with smaller tick sizes. I understand the intuition that the ability to compete more on price should reduce the need to compete on speed, but surely it's more complicated than that.

Would love to see some research if it exists.
At this point I doubt it is hypothetical anymore but more a question of how long it is there are using small drones in their current spying operations.

That's interesting, but those children were already exposed to civilization and in contact with language-using humans.

How likely is a human to develop any of our abilities that we take for granted, in the wild?
Your first point is literally just market making, which requires absolutely no HFT. Your second point (arbitrage to keep prices in line) also doesn't require HFT and I find it awfully difficult to imagine that (actual) people would need to worry about where to get their stock if arbitrage would occur at less than microsecond frequencies, because otherwise there might be significantly out of line prices at timescales people care about (many orders of magnitude slower).

According to Bloomberg, the U.K. plans to propose blocking Russia from the SWIFT banking transaction system, a move analysts say would effectively cut off Russian businesses from the rest of the world's financial system. U.K. Prime Minister David Cameron will put forward the proposal during a meeting with E.U. leaders in Brussels on Saturday.

I was "in to computers." I liked looking through files, new software, and drawing in ms paint. As I started at university, my buddy said, "you should take a programming class." I took CS101 in C++. I got an easy 4.0 and he hired me at his start up doing PHP. That was the start. Then I went into insurance, financial advisement, and teaching math in highschool. All the while, tinkering and toying with programming and some odd jobs (all the while raising a family that we started a bit early by conceiving at age 15). After failing at insurance, failing at financial advisement, and failing as a teacher (which all hurt), my side projects caught the eye of a recruiter, and I interviewed at a few places. I ended up with a great software company where I have grown tremendously and am now (years later) a principal engineer. I love what I do and I think I am pretty decent at it :). What does this mean for your kiddos? Find something they like on computers and link that to a programming problem. Helo them learn that a computer is a tool and a tool they can alter and control to do what they need done. There is no magic there.
Going down the Wikipedia rabbit hole and reading about Papa Mau's tiny home island of "Satawal":

https://en.wikipedia.org/wiki/Satawal

"On March 18, 1994, the freighter Oceanus ventured out of the main shipping channel when its captain attempted to peek at topless Satawalese women. The freighter ran aground on the nearby Wenimong Reef, the primary source of food for the islanders, and 13,000 square meters of the reef were ravaged. The freighter's insurer, the North of England P&I Association, ended up paying US$2 million in compensation to the Satawalese.[2]"
"More efficient" is not a binary thing. Taking an efficient engine that's capable of throwing two tons of steel down a highway at 100 mph and using it to charge a lithium ion battery is like killing an ant with a sledgehammer.

An F150 consumes ~2 litres of fuel an hour at idle and provides 400 watts of power through its outlet. A Bosch leaf blower is 2400 watt. Petrol powered leaf blowers do not use 12 liters of fuel an hour.

Sure, the emissions in some ways will be lower, but it's not an unambiguous gain and it's not anything close to an environmentally friendly way to run a leaf blower.

This is clearly a niche for PHEVs or BEVs.
Why would that preclude the ability to host certain zones only on internal DNS servers?
I worked in Vancouver at a well-regarded company making under $100k CAD ($70k USD). I shopped around the job market there and didn't find anyone willing to pay over $110k. Everyone I talked to seemed to think my salary was competitive.

I expanded my search to Seattle (2 hours' drive south of Vancouver) and received multiple offers over $200k USD. I'm making over three times as much as I could have in Vancouver. And my taxes are significantly lower.

That said, I wouldn't mind moving back to Vancouver someday. Curious who is paying $200k in Vancouver, and also whether you are at the high-senior level that would net $400k+ at e.g. Google in the US.

Interesting that we apparently saw two very different sides of the job market in Vancouver. Thanks for your perspective.

Zero benefit. They were not like human calculators, but more like middlemen, mainly because access to the markets was difficult.

Now as everything has become more efficient, humans are replaced by algos, which are way cheaper. In turn, they also require less for upkeep, and so charge less in edge, which means you have better bid/ask prices, lower trading fees, etc.

QBASIC.EXE! When I was in high school, there was this small program (small enough you won't delete for extra space for games) included with DOS that contained everything you needed to create a small program.

Today's official answer would be Visual Studio on Windows or Xcode on macOS which aren't simple or small.

The most similar contemporary approach to that simple game making is probably the 2D game engine LÖVE, which is awesome

That seems like something you may have a decent chance or redlining, particularly if it is a competitive offer, no?
> notice how many cars have advertising for the dealership on them as stickers or license plate surrounds. Why do people leave that junk on their cars?

I do have a dealer license plate surround for a dealer that's 3+ hours away; we got the car 2nd hand. It's entirely because I don't care enough to change it, as it would cost me money and time.

There's probably the opposite of signalling going on somehow here... where I'd rather people who think that makes me tacky stay away from me because I think they're shallow. ;)

It's weird when you are part of a larger org; you still worry about technical debt as a team, but you have to also deal with, like, institutional technical debt.

Realistically, something like 10-20% of the engineering resources at a company like Google or Microsoft are going to service technical debt at an institutional level. Sometimes it is literally all an engineer does, like maintain a deprecated system that can't be turned down for five years or a team migrating large systems from the old and busted to the new hotness, sometimes it's just the tax on engineers doing other projects to work around the technical debt. It's just what happens when you have tens of thousands of engineers working for decades.
The trick is, that barring accidental death (including accidentally falling victim to someone elses intentional killing of you), you will stop wanting to live before you die. So take care of yourself, preserve your health, and enjoy your life -- by the time it's over, you won't want it anymore. So don't fear death; only fear harm in your life.

Also, remember that when you're gone, it won't hurt, and you won't miss anything. Everything in your life, from the worst torture to the most minor itch, hurts more than being dead.
Not only that, but he used the same or a very similar username to spread the news about the Silk Road market on a different website. (Of course he did this in a plausibly deniable way, but if it turns out that the same guy has been asking for help with making that kind of site on SO, it doesn't take much to put two and two together...) Not to mention the other mistakes he most likely made while running the site, which (when brought to light after the investigation) proved to everyone just how far that dark market was from the "libertarian utopia" DPR liked to talk about. Of course there's a pretty big selection effect here; we would expect the people involved in something like SR to be quite overconfident and perhaps overly motivated by greed, and thus to be more likely to do some of these things.
Do you really want to drag gender wars into this? How many of those unpaid daughters are getting their needs paid for by wage-earning spouses?
Well, chaos theory is explicitly not a denial of determinism, and speaks more to our ability to precisely measure state and accurately model it than anything else. The more precisely you can can measure state, the longer the Lyapunov time, and the longer we can accurately predict the future states of the system.

There are systems today that we can predict fully (i.e. we can predict what will happen faster than it can actually happen) that decades ago would have been unpredictable due to their chaotic nature. There are systems we cannot predict today that we will be able to in the future. Brains very well could be one of them.
I think he meant Interstate highways, such a large infrastructure project would be impossible to get through congress today. I hope that the attitude towards these types of projects change soon. America could be such a better place if we could invest in our infrastructure and citizens
Traders already look beyond one interval. An order I put in yesterday that took 5 minutes to execute still beats an order I put in today in 10 nanoseconds.

Being fast is important for cancels & risk management. Which answers the question on what it provides. It lowers the risk for the traders allowing them to price tighter.

There are third options, you know, even in an old folks' home. Like relaxing and winding down. Just because something doesn't look "cool" doesn't mean it's unpleasant or unworthy. Some people would rather be dead than be nerdy, or jocky, or whatever.
> As much as smog "has been"? Los Angeles today is still full of SUVs belching smog. The air quality is still insanely awful. Yet the dialog has moved on (maybe because SUVs are for the wealthy?).

Meh, there's no need to resort to conspiracy theories to explain why the conversation has dropped off the radar. The level of smog in LA is _drastically_ lower than its peak, both quantitatively (as one figure, ozone levels are 40% of what they were in 1970) and in terms of how the man on the ground experiences it. Most people stop caring about a problem when it stops being so dramatically visible.

Let's say a single VM or docker container has a break-out exploit. They get the private key for (whatever).domain.tld. It would be nice to be able to issue whatever yourself, rather than having to A) do wildcards or B) expose every single record to CT.

But I personally don't tie privacy to DNS. Best systems I've seen which handle sensitive stuff have very ambiguous DNS names which you would never guess what they really are.

> We also use docker because it lets us build things that our IT crew isn’t certified in running infrastructure for (and the lovely security issues that brings to the table) but we mainly do it because it works.

It is amazing how many technologies get traction simply because "It lets us bypass IT."
It was these sorts of websites which led me to fall in love with the internet. How far we've fallen. I miss those heady days.
No, I've got the point being missed. I just don't find the distinction useful at all.

The whole point being made was that "metaphysically speaking, it's not at all obvious that we "didn't exist before birth".

Which I say is irrelevant, if we need to distort "exist" so much as to mean some "larger processes" or our "atoms and molecules" existing.

Metaphysically speaking it might not be obvious, but the way the grandparent, me, and almost everybody else uses the term existence (i.e. regarding the conscious person, or at least their soul) it's obvious that we very much do not exist.
I think stuff like this is what made America great so the MAGA guys should be all for it.
I used to have a keyboard back in 2005 that was made by a company called FingerWorks. The keyboard came in two halves and used virtual keys and gestures. You could get it with either Qwerty or Dvorak layouts printed on the smooth surface. They also made a replacement keyboard that you could install in MacBook Pros. Apple acquired the company in 2005 and used the technology in its products.

I really liked my FingerWorks keyboard, but it kind of died out for me once FingerWorks stopped producing firmware updates for it. I don't know how well this keyboard works, but I'd be happy with it if it worked at least as well as my FingerWorks keyboard did.

Has anyone here done commercial lawncare? I mowed cemeteries and churches for 5 years. Electric tools might work for a tiny suburban plot but try doing even a single cemetery with them. We only used leaf blowers at the cemeteries a few times a year (Memorial day, etc.) but there is no way an electric blower would last long enough.

D.C. has Arlington Cemetery too, so I'm not sure what they'll do. Maybe they have an exception.
What if you knew the names of some of them but took a guess at the rest? Including the names would confirm your guess.

Well this is the inherent push-pull of the industry, isn't it? The ones with money generally have insane compliance requirements (because they have money, they have more risk); the places without money care more about getting things done (since they're trying to make money...).

It can never be defined, because the entire point of a politicized term is to carry a loaded definition that goads a fraction of the other team into agreeing. Most reasonable people do not think that "political correctness", meaning a need to conform to The Party, is a good thing. The difference lies in what types of situations the term is applied to and how much it is emphasized.

It's impossible for relatives to make these decisions. It's also almost impossible for the people involved to make these decisions.

I know someone who was put into the situation of having to decide whether her very elderly mother, who was in a coma, should be put through emergency treatment, or allowed to die.

She made what she thinks was the wrong decision - but of course there was no right decision. No normal person could ever find that choice easy - which is why we try to leave it to doctors who aren't personally involved.

I also know someone whose mother had a severe stroke, which left her unable to move or speak. She's absolutely convinced her mother was trying as hard as she could - unsuccessfully - to tell her she wanted her suffering to end.

End of life is unbelievably traumatic for everyone. Unlike most life changes we get almost no warnings about what can happen, and no preparation for it.

Sure, I'm not saying the article is off topic. If it were, we would demote it (or rather, it would already have been heavily flagged). The issue is simply that when people respond with shallow dismissals, especially with a provocative edge like "wouldn't touch region X with a ten foot pole", it leads to lousy discussion. Worse, in a case like this, it pours fuel on regional resentments, which unfortunately are a lot stronger than one might have hoped.

Admittedly the article set itself up for such a dismissal by making a provocative generalization about "smart people" in the first place. But commenters here need the discipline not to take the shallowest bait in a piece, but respond to the parts that are actually interesting. In a way, that's the article-scoped version of this guideline: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize."

Also consider the path: you can pretty much do a great-circle with radio.

A cable is not going to be direct. If it's above ground, it needs some slack on the line to account for pole movement (you don't want your fibre holding two poles together...).

You'll need more slack for your splices to be done at surface level during construction. Splice trays every x meters will add more distance.

Sometimes the poles are overloaded and you need to run down and bury it for a while.

Your tunnels are never really straight. You need to follow existing easements, or get your own. When you do bury, you need to go around various physical obstructions, like rivers, buildings, cities, parks.

And if you want redundancy against back-hoe fade, your latency in those situations will shut you down, perhaps erasing your profits when you're down and your competitors are up.

The cost of running your own line point-to-point would be be monstrous, though I guess you could build in some latency and sell access to non-HFTers.
