For nurses on-call is a tiny amount - $3/hr and then you get 1.5x if you actually get called in

When I was at a small IT consulting shop ~15 years ago, this is roughly how it worked. We'd get paid 24x7 for a week on-call at minimum wage + 1.5x normal wage for any hours we had to log in.

Since light travels at 100% the speed of light in a vacuum (by definition), I have wondered if latency over far distances could be improved by sending the data through a constellation of satellites in low earth orbit instead. Though I suspect the set of tradeoffs here (much lower throughput, much higher cost, more jitter in the latency due to satellites constantly moving around relative to the terrestrial surface) probably wouldn't make this worth it for a slight decrease in latency for any use case.

Hollow core fiber (HCF) is designed to substantially reduce the latency of normal fiber while maintaining equivalent bandwidth. It's been deployed quite a bit for low latency trading applications within a metro area, but might find more uses in reducing long-haul interconnect latency.

> Fixing the frame length doesn’t have any effect on higher-level protocols because they encode the packet size in their headers and do not rely on the actual Ethernet frame length.

Interesting. I just wrote a packet decoder and I specifically verify at each layer that the lower layer length matches. So for IP, in my decoder the IP datagram length must match exactly the ethernet frame length + link layer header. I didn't do this to be pedantic but rather to detect short frames, and then I decided that long frames were also errors.

You (author) are using uIP but I wonder what Linux or any other modern OS does. You don't specifically mention interoperability but I wonder if you've tested that.

Timestamps and other types of in-band network telemetry are sometimes inserted in the frame as a trailer (with a new FCS). If an application isn't looking for the L2 data, it's just ignored by the Linux IP stack.

there is a company where you can submit your bills if you suspect overbilling. they have professional coders on staff and they will find fraud or overbilling on your behalf and also sue the hospital too

medical billing fraud is a serious offense that can get the hospital in quitw hot water and they leverage that

darrin · 2 years ago
What's the company? I've wanted to outsource dealing with medical billing games a few times.

> Of all the scams associated with real estate transactions, title insurance is kind of legitimate

As someone who has submitted (and failed to collect) on a claim against title insurance for legal fees incurred to correct a mistake in the original title that the title company missed, I'm skeptical of its value, at least for things like erroneous lot lines.

My family raises beef cattle on the side, mostly in the past it was just to help keep the property grazed down (it'll go fallow pretty quick if nothing is on it) and provide local higher quality, cheaper beef for folks in the extended family. At some point, my parents decided they wanted to try expanding the farm and actually selling the beef. They were shocked to learn that two guys control the local cattle markets and pay essentially "what they want" for anything and everything. Pretty much no one got more than $1/LB on the hoof for grass fed healthy cows.

They gave up and went back to a property maintenance sized herd after 10 or so years of that.

There's no broader market for beef? Is there a higher break-even point factoring in transport costs?

Flat salary is an incentive to do the easiest option or least work. You can’t win with the incentive game.

One nasty way that can manifest is to under test because if you don’t find anything you don’t have to do anything.

A bonus based on risk-adjusted outcomes would put pay in alignment with patient care. This would require much better outcome analysis and reporting though (also a good thing).

If you buy a stock, you must keep (hold) it for eg. 30 days (or 7, or 60, or whatever).

Compute all you want, whenever you want, but instead of millisecond timings, optimize stuff for at least some time.

Maybe even a tax on stock profits, which is really high and falls after some time of ownership of such stock (we have this in slovenia, but it's not really high in the first place, and time brackets go less than 5 years (25%), 5-10 years (15%), 10-15 years (10%) , 15-20 years (5%), and zero tax after that.

Adding this sort of friction would increase spreads. Market makers are a net positive for markets (who buys/sells when no one else wants to?), and I don't see any downside to allowing them to manage risk and trade quickly. I think the way to increase fairness is to change the way orders are matched.

What would that look like? If you rate limit stock exchanges to something like 1 update per minute then there will likely be the same amount of networking and computation going on to speculate on the next update and calculate optimal plays. It just moves it to behind closed doors where it is harder to know if shenanigans are going on.

It would take a heavier hand to push against this problem. I'm all for it, I'm just not clever enough or knowledgeable enough to know what would be a good regulation that would fly in congress.

The best solution I've seen is to do batch auctions every millisecond or so, and randomize matches within that window (for market orders or limit orders at the same price). You could use a longer window to include slower players in the market.

How about forcing public markets to bucket trades within say 2 second windows, executing best matches at the end of each period. Low friction and reduces value of millisecond latency advantages.
darrin · 2 years ago
Even a 1-2 millisecond batch auction would do it. But the big trading firms are the largest "customers" of exchanges, and they've pushed back hard on proposals like this.
