> How can anyone know these aren't a threat without knowing whose they are

They are - obviously - lying. This screams secrecy to me. All 3 know that these drones are not a threat. They aren't US military because they are a 3 letter agency program. They know there's nothing to worry about it, but they won't tell you any more details. Which has been the modus operandi for secret services for decades, so I'm surprised it's such an issue?

I think what's so surprising is that they would run a secretive program in such a conspicuous manner, not that the secretive program exists.

At least in Europe and the Nordic systems I have experience with, that typically applies to the very expensive novel treatments. There are gene therapies which can cost $2-3 million per patient and those aren't covered by any public healthcare system, AFAIK.

But it's not like there is some kind of upper limit on coverage. If you have cancer, you will get treatment regardless of how much your care has already cost.

In most of the places I've been in SE Asia and South America, there are separate government hospitals that are the only affordable option for the poor. If you have cancer, they're not going to do much for you.

It's hard for me to understand how Tinder is not dead yet. One big pile of pop-up ads (even when you pay you get upsell popups) and some Chinese scammer bots.

It's highly dependent on location. I use it while traveling, and yes in a few countries it's useless, but I've met 300-400 people over the last 7 years. It's added more value to my life than any other single app (even though I've never paid a dime for it).

For the record, I'm male, mid 30's, and average looking.

It's fairly common for governments to provide a basic level of care for free or heavily subsidized, but not cover more expensive treatments. It's certainly not exclusive to the US.

So you are saying HFT will avoid your market order in this case, while HFT will provide better price when they are the sole counter party in separate liquidity pool? HFT will always maximize profit. To have multiple venues you are just paying HFT as middle man to transfer liquidity from one to another, where you can trade directly with each other if everyone is on one venue, e.g. one centralized limit order book. Transfering liquidity is not HFT's fault, but saying paying for order flow is better for retail is just disinformation. Without evenly discussing the function of HFT, you will get disinformation that demonize HFT as well, and common people won't listen to you later.

Yes, absolutely. The best feeds (tightest spreads) are only given to specific clients who are requested to trade exclusively with them. If they detect you splitting your orders up between venues, they'll worsen your feed. The feed they'll send to public lit ECNs will generally be their worst (widest spread).

You don’t have to trade with market makers.

rjrdi38dbbdb · 9 months ago

So you're hoping get price improvement by crossing with other trader orders in the book?

Unless you have a good high frequency predictor and low latency order management (you don't), you're going to experience adverse selection. Either because you're taking resting orders that HFTs are smart enough to avoid or because your resting orders get run over by informed traders.

It's not. Centralization of liquidity is better for everyone. HFT thrives on fragmentation of liquidity. HFT is not wrong, but fragmentation of liquidity is.

rjrdi38dbbdb · 9 months ago

Nope. It's not better for known uninformed traders. If you mix them in with informed traders, market makers must widen spreads.

This is very obvious in institutional FX. Pure "retail" flow will get quoted much tighter spreads by banks and market makwrs than you'll see on any ECN. Yes, it can get skweded against predictable flow, but a true "noise" trader won't be affected by that and will definitely be better off with tailored liquidity.

The title seems misleading. Unless I'm missing something, all he did was scrape a news feed, which should only require a couple days of work to set up.

The fact that he left it running for years without finding the time to do anything with the data isn't that interesting.

Some people need to live in "the sticks" to produce the resources (food, ores, oil, timber) that the rest of society relies on. Subsidizing the availability of services for those people doesn't seem unreasonable, and it is certainly something the federal government has historically taken responsibility for (for mail, electricity, telephone).

rjrdi38dbbdb · 9 months ago

Why not just let the market find its own equilibrium? If people need to live there to produce valuable resources, then the cost of those resources will naturally rise to cover the expenses of those employed in those industries.

If you compare the historical rate of improvements in computing power and algorithms vs rate of improvements in building scale, you'll find one is a whole lot more likely to reach its goal, even if the rate of progress slows significantly.
