> most brazilian commenters here will zero in on everything that's wrong about Brazil, regardless of the facts. I don't yet have a grand theory for why this happens, but it usually does

It’s the age of Brazil (governmentally speaking). The current republic is fairly young and so the popular view is the equivalent of a twenty-year-old college student that is into libertarianism and thinks that all regulation and bureaucracy is bad and that the market should decide all things

Still better than paying for trades and being front run I guess.
It depends on your definition of fun; some people enjoy office work, others don't. Some people derive joy from the status they assume from their job, others don't.

Most 'workable' jobs have one thing in common: you get something out of it. If you are lucky, you get both material and immaterial, but often, people chose to deny themselves one for the other, instead of balancing it (and in turn often don't find themselves in a good work/life balance either).
What did you leave the field for? What do you do now and are you happier since leaving?
Just because is human nature to think history could repeat itself, he is looking at the next crisis from a similar angle, which is implying lighting striking twice. I would look at polical or after shocks from a melt down from another super power.
You can always use `if` to handle errors like now. Handle/check is a addition to error handling but not replacement.

Function arguments can be placed on multiple lines, that would make `check` expression more readable.
I don't understand how this works?
The stock price is the same for the buyer on RobinHood or does RobinHood raise the price in anticipation?

One of my favorite articles of recent times. What jumped out at me was that there is a dramatic difference in start up time depending on how much memory your cloud server has: the more memory, the faster the start up time.
Turns out that recent studies say you’re wrong. Counter-intuitively, making rational, fact-based arguments actually makes “them” reject scientific fact even more strongly. Look it up.

It means they are handing over your transaction to HFTs, who can then see your transactions ahead of everyone, and buy the stock right before and then sell to you for a higher price. Imagine you just issued a BUY order at market price; they can buy at $99.9 and sell to you for $100, making a $0.01/stock profit. Rinse and repeat millions of times per day.

This is very similar to "front running" [1], but because a) this happens privately and in small quantities, and b) it is not necessarily privileged information, it's considered legal by the SEC. But it is highly questionable for sure.

"Flash Boys", by Michael Lewis [2] is a great read, and goes into detail on the world of high frequency traders, and how they operate.

Why not just do it on 11/9 instead? Or 3/11, six months shifted?
I think the implicit assumption is that HFT firms place a negative externality on the overall stock market in a manner which CAN distort the value of holding the set of equities being traded. As a hypothetical example, if 90% of Robinhood customers bought into a pump and dump scheme, and HFT wrote the algorithm to perfectly go long at the perfect time, and accordingly sell at the perfect time, then the less educated investors would essentially be subsidizing the HFT firms ability to turn a hefty profit. This kinda isn’t so much a problem by itself. It’s when the dump in the pump and dump is exacerbated by the HFT firms, which wipes out all of the Robinhood investors positions: Robinhood facilitated trading -> millennials bought into a false hype -> HFT knew this could happen and wrote an algorithm to capitalize on the inevitable correction, and slurped up the mismatched price difference contributed by these investors.

If this is the implicit assumption, the article still falls victim of a slippery slope fallacy by letting readers believe “if Robinhood does this, what other companies can sprout up to encourage HFT exploitation?” Regardless, the article points to a good discussion in the direction of “at what point do we expect HFT to be the only way to benefit from the stock market?”
Foxconn is already replacing workers with robots ("Foxconn replaces '60,000 factory workers with robots'" https://news.ycombinator.com/item?id=11770463) and I'd argue so do car manufacturers for 50 years step by step. I don't know if they could reach 100%. In other industries, e.g. food processing, it seems humans are only needed to fill up the ingredients, watch monitors and do QA.

What is front running?
dear young people who are reading the above comment.

IMHO dont be afraid to take it with a grain of salt. don't expect to be rewarded for saying no. don't expect a light feather ruffling. don't expect light consequences. be prepared to get fired. be prepared to get demoted. be prepared to lose your health insurance. be prepared to change your industry. be prepared for the realities that most people face.

if you say no to something that really is important, then there will, the vast majority of the time, be major consequences. dont expect it to be easy. dont expect a reward. dont expect anyone to even understand or care why you are doing it. dont expect to be respected. dont expect anything. be prepared.

when you are living in poverty or are homeless, that no wont really mean much. only say no when you have the ground to stand on that can catch you when the inevitable smack in the face comes.

and dont feel ashamed if you have to say yes to survive once in a while. its actually what most people do. every day. even people you respect as heroes. sometimes especially the people you respect as heroes. when a really big no comes, there will be many people chanting it together, and many others behind them silently backing them up, all of whom had to say yes, in ways large and small, at some time or another, in the past, just to survive long enough to be together in that space, building that critical mass, and supporting each other.

Interesting. So basically RobinHood has so many buyers and it lets them see a bunch of trades for a stock right before a large subset of these trades happens, then they HFT trade microseconds before the trade happens and ride the wave upwards? Or vice versa downwards?
One of my physicians won't take me seriously because he's had too much of them and their abuse of the internet. He would rather that I stuck to exactly what he had prescribed - that was failing - than humour me, my degree, and my academic journal access.

Fortunately, the specialist he referred me to was pleased with the steps I have been taking.

I can't really blame the first specialist - I'll concur that he is going to do the greatest good to the greatest number with his tactic. But, it means that our interests are in conflict: not an ideal relationship to have with your medical counsel.

Imagine you place a limit order at $101. The HFT sees the stock dropping to $100. The HFT then has the option to buy the stock at 100 and sell to you for 101, making $1/stock profit.

On the other hand, imagine the stock is currently trading at 105. The limit order will hang there, waiting for the price to drop below the limit you specified (and either never gets executed, or then becomes the flow above). Rinse and repeat.

Note they don't need to make money in every transaction, but the bigger the order flow, the more opportunities they have to make profit on top of traders.

There is a lot of blame to go around but It would be nice for people to actually realize what is obvious post-factum was not really obvious at the time.

Reflections on the Revolution at Yale
The data infrastructure and sunk costs are quite high for systems like this, and the non-zero defect or failure rates mean you still generally have to employ most of the same staff.

Right, which is why one could reasonably speculate that CBP is picking up the cost of the system. Without the capital costs it could easily make sense.

The clincher would be how edge cases are handled. Is CBP paying for a human behind the scenes to remotely override rejections? Is it acceptable customer service for falsely rejected passengers to wait at the gate until shortly before departure when an airline employee can show up to double-check their documents?
Google's AI Cloud Star Leaves After Pentagon Deal Protests
Perhaps you could have had a variety of team (or wider company events) where not everybody needed to go to every one.

On a practical basis, more “all hands” (aka mandofun) events do need to be inclusive. In normal companies at least. This is usually considered alongside basic personnel stuff like catering for allergies and dietary preferences at shared meals.

In my experience most organisations don’t have huge problems with this although the mandatory fun often isn’t.

I also believe that major company/team decisions probably shouldn’t be made at bars but I get that not all companies are for everyone.
I hope we get something besides Backup and Sync as a replacement for Google Photos Uploader. My workflow broke when Backup and Sync doesn't work the same way, and not as consistent. I can't only upload photos, and it seems to try to vacuum up other files, so I've just told it to stop since they broke the Googel Photos Uploader API.
HFT and front running are two different things. HFTs could front run, but by definition don’t have to to be an HFT.

Actually, there's a lot of activity, responsibility, and work to be done once heaven arrives. A few thoughts:

In the final state, there will be new heavens and a new earth (i.e. a very physical Earth like we know it now, with mountains, trees, grass, animals) -- a sort of Eden restored, but better, since God's throne and presence will be on the earth, instead of in a separate place (Revelation 22, Isaiah 11). There will be cities to rule, a lot of responsibility and work to do, many "ages to come" in which things will change (scripture references provided on request).

Imagine the grandeur of Tolkien's and Lewis's fantasy novels -- the ages upon ages of interesting history and characters. I honestly don't understand how the narrative will work without any antagonists present, because we presently understand narratives via conflict and resolution. The "they lived happily ever after" seems rather bereft of content, and is kept for the very end of stories. I suspect that's because we have yet to see what the great, true "happily ever after" looks like.

However, the boredom with eternity that Orwell alludes to will not be present, simply because of the person of God. He is full of infinite love, creativity, power, etc... and he will be the delight of all who are there -- that sort of ever-flowing fountain of life and "newness". Indeed, without God himself, everything would get incredibly dull after a while. Jesus says as much in his prayer to the Father in John 17: ".. and this is eternal life, that they may know you, the only true God, and Jesus Christ, whom you have sent." The "life" here is love, joy, and peace, not merely length of days.

You most certainly can. The market cap (current price) is not a function of the amount of capital put in. You can put $1M into a company and have a market cap of $1B or put $1B into a company and have a market cap of $1M.

I understand your argument, but try for a second to see it from my perspective: the end-to-end argument pretty strongly implies, to me at least, that to get meaningful security, you want to provide it in higher-layer protocols, closer to the endpoints. What's wrong with taking a layered design like TCP/IP and simply drawing a line, below which we don't try to provide cryptographic security?

We've been doing that for ~30 years now; it is the only means of providing cryptographic security on the Internet that has ever actually worked.

You're calling this approach "workarounds", which, sure, they're workarounds, in the same sense as TCP is a workaround for IP's native lack of congestion avoidance.

That's pretty cool! Manual labor, personally, is appealing after a week of desk work in front of a computer - the sun, the frequent breeze, sweating, etc. It's one of the reasons I added philosophy as another major I'm pursing along with computer science - makes think about something other than computers and it gets me off the computer, even if it's for a tad bit.
Unlike doctors, vets euthanize animals every day. They're comfortable with the idea of a medically induced death. Ask any vet if euthanizing animals makes them uncomfortable and they'll tell you it doesn't bother them at all because they know they are ending the animal's suffering humanely.

On top of that, they have access to lethal drugs and know precisely how to use them, how to end their life quickly and painlessly.

Those two together make it very easy for me to see how a vet would rationalize suicide.
Trust in this context means "If I loan you money, how skeptical am I that you'll pay it back?" I can be skeptical for a number of reasons, from the simple notion that I think you are just a crook and have no intention of paying back, to more directly economic ones like the fact that I know you've got no real prospects to make back enough money going forward to stroke the interest on my loan. There are shades in-between, like if I know you intend to pay back the loan and can technically afford it right now, but your credit is bad all over town and you're one bad break from being totally and irreparably insolvent. If you're family or a close friend, I might loan you money without seriously expecting to get it back (though in these circumstances I personally just recommend just making it a gift).

By "how much material is being dedicated toward...[it's]...future existence" you presumably mean how much the firm or individual is investing in relation to their income or some similar measure. That can be part of it, but definitely isn't all of it. All market transactions are, contrary to the technocratic worldview of mainstream political economists, human transactions. The actual underlying human relationships matter, and the balance sheets only matter inasmuch as they facilitate communications between actual people.
Privacy vs. security... it's a complicated. Nobody cares that the police can tap a phone line... so by that logic, why can't they tap any other communication medium?

But... what I do know is that the Australian government is not the one to solve the problem. They're a small market, without a lot of technical expertise... having lived in Sydney for some time now... I know you don't want the Australian government involved in tech.

It's worth noting the big downside to enabling PLPMD is of course that connections which are broken are unlikely to get fixed, but it can result in extra latency or lower initial connection performance which is then hard to diagnose. As opposed to being just broken and fixed by the administrator/network operator/user/etc in the first place.

Most of the time the MTU issues are relatively local to the user, e.g. their router isn't configured with the actual MTU of their internet connection, etc. and can be fixed by them (as opposed to by the ISP etc)

Not quite. If I understand correctly, the requirement is that any model of the graph with arbitrary edge lengths can be "flattened" into n dimensions, without changing any edge lengths. This is not necessarily stronger than planarity; in particular, according to these slides, the complete bipartite graph K3,3 is 2-realizable but not planar.

I'm not sure what practical applications there are for this area of theory. But intuitively, it seems like the "flattening" process captures some notion of rigidity. For instance, there's a sense in which a 1-realizable graph is as non-rigid as it's possble to get. If you make a physical model of a tree, using (idealized, infinitely thin) rigid rods and joints, the tree can always be folded up so that all of its edges lie parallel.

Similarly, a 2-realizable graph consists of rigid, flat pieces, connected along their edges by "hinges" that can always be folded flat, whatever their original configuration.

So maybe this could be somehow applied to the automated design of structures that can be assembled from foldable pieces.

If you want to see that sort of thing in the SF Bay Area, visit the Marine Radio Historical Society in Marin.[1] They have a big ship-to-shore station, built on Federal land a century ago and turned over to the Park Service when it shut down.

They operate many of the transmitters each weekend. They applied to the FCC for a commercial coast station license, probably the last one, and got it.
So they can send at quite high power. They talk to museum ships around the world.

I’m skeptical of the faster boarding claim. My perception is that it’s the physical loading of the plane cabin, rather than the scanning of boarding passes, that wastes time. Also, having dealt with the face scanners at the border entry points I’m also skeptical that self service face scanning will be faster than just scanning a boarding pass. Not to mention that security, not boarding, is the painful part of the process anyway. And 99% accuracy is not actually great...
Graphene enables clock rates in the terahertz range
I see the issue after digging in more. The problem is that Robinhood claims they make money by investing in fund with extra savings, however they failed to address how they are "really" making the money. I always doubted how they make money and now I know.

What's even more surprising is that other company like E-Trade costs money AND they sell it to HFTs.
