I hope one day we stop comparing rail to cars on passenger-mile basis - like infrastructure costs per passenger-mile. These are apples and oranges. There is zero similarities between riding on modern trains and driving.
I’ve taken hundreds of trips, anywhere between 2 and 8 hours, on TGV, ICE, and Eurostar trains in Europe. I loved it every time and came out refreshed even after longer trips. At times when I wanted to get work done (probably 60-75% of total time spent on trains) I was as productive - likely more productive, due to lack of distractions - as at the office. In contrast, I don’t think I can remember any road trip lasting more than 2 hours when I could say I enjoyed it; many times I was so exhausted that I needed rest upon arriving to destination.
So, if we are going to try to fit this into some sort of economic model let’s not forget about countless billions of hours of productivity loss due to people stuck behind the wheel staring at traffic.
Not to mention both emotional and physical strain associated with driving (nope, can not stand up when you like, or walk over to the buffet car for a coffee), respective health care costs, and more productivity losses. Once we do that, the picture will be very different. It’s sad we in the US haven’t realized this yet.
HFTs quote in a given symbol, often derivative e.g. “AMZN 2000 strike call option” based on market in another symbol, often outright e.g. “AMZN stock“. They are willing and happy to trade at prices quoted while market in AMZN remains what it is. Once it moves, they re-price their quotes in option(s). Their quote sizes are usually pretty small.
Spoofers put out orders without intention to trade. In fact, usually they would be horrified if their entire order trades. Their order price is not based on another market; their only intention is to impact prices in the book where they put the spoofing order. To achieve that, they often use disproportionately large order sizes, such as posting quantity 1000 where most other orders are between 1 and 20. Often they keep “applying the pressure” on the market by modifying the large spoofing order multiple times towards the market - moving the sell order lower and buy order higher - not as a response to changing market conditions in some other instrument but with the sole intention of impacting the price in the book in question.
This is great but what jurisdiction does SEC have over Ukrainian entity? Sounds a bit like robo-callers with gozilian in fines issued and near zero collected.
Interacting with the US banking system is necessary for trading on US stock exchanges, which means that they can be essentially banned from the US banking system on pain of getting all their money seized.
What jurisdiction does the US have to nab Somali pirates off a skiff off the coast of Africa and bring them to trial in NYC? What jurisdiction does the US have to kill terrorists on foreign soil?
Probably a lot less jurisdiction than people mucking about in US markets...
One more interest feature which was not clearly described: you can attach two or more ssh connections (belonging to the same system user) to the same tmux session. Each displays the same thing in real time and has full control.
We use this all the time for these two use cases:
1. Semi-permanent connections to the same tmux session on the server from multiple locations e.g. work and home. Come home and find things exactly the way you left them at work, and vice versa.
2. A sort of collaborative environment. We have something like “demo” user running tmux session, and multiple people from different remote locations login as “demo” and attach to the same tmux session. Again, everyone has full control and we can see each other’s actions as we also talk on the voice call in parallel. Usually much better experience vs. some sort of screen+control sharing solution, especially when some participants are on low-quality connections.
These “income share agreements” seem to be an emerging phenomenon. I wonder if anyone here could comment on any limitations to their use. When someone voluntarily signs an agreement giving me P percent of their income from working as E, for Y years in return for some consideration C: are there restrictions on (P, E, Y, C)? And what sort of laws/rules generally regulate these in the U.S.?
They seem dubious at best, at times I’m surprised that people don’t just find ways to have a lawyer break the agreement after they’re hired. In certain cases it could be cheaper to do that than continue being robbed.
Maybe are loopholes if someone wants to go find lawyers and pay enough legal fees. Thankfully we haven't had to deal with this issue as our students have been pretty satisfied.
I wish I could comment more on the legality of the income share agreements, however, I end up leaving that discussion to a lawyer so I don't have much input here.
It does not work entirely on votes. The mods have quite a bit of weight in deciding what gets pushed to the front page.
For example, there's an article about gorillas on the front page right now that has exactly 7 points. HN is nowhere near that anemic that 7 votes would be enough to push to the front page on its own.
To boot, I once submitted something that went unnoticed. An HN mod then emailed me and said it looked cool, asking me to resubmit it again so that it could get more prominent featuring.
