mcgoo | 5 years ago | on: US may not be back to normal until 2022, Fauci says

If you want to avoid crowds, the two busiest days for the courthouse we got married in are Thanksgiving Friday and the last Friday in December. There were six judges on the day we went - typically it’s handled by one judge. (That was 2018, who knows how it’s going to be this year. Might even get shut down in some places.)

mcgoo | 5 years ago | on: U.S. FAA proposes requiring key Boeing 737 MAX design changes

The MAX is also known as the 737-8200. Now that the product recognition is working against it, I think we will see the forgettable name a lot more.

At least in the US you can typically cancel a flight for free within the first 24 hours if it is booked more than seven days out, if that helps.

You are right that the airline can change the type of plane like that but it is uncommon. A much more common way to end up on a different type of plane than was booked is weather cancellation. (Personally, I don't like most of the regional jets, but by the end of the day of waiting for a 1 hour flight, I'll take anything.)

This is something that keeps coming back to me either as a feature or as a product of some kind - a tool that can stop this from getting in our way.

The simplest and safest would be to apply the formatter to both the old and the new copy before diffing it. It ceases to be the actual difference at that point, but there are definitely two distinct use cases for diffs - one for humans to read and one for the machine to apply.

The other case that would be amazing but even more of a stretch would be to rewrite the entire history. It seems like there is a spot for "different views of history" and you could do a no-difference merge to join the to histories as of now so that the actual history did not get lost. As I write this, it starts to sound like just a caching system for the idea above.

This needs a highly reliable formatter of course... I have on occasion had code broken when formatting.

The leveraged ETFs have a few extra footguns, don't they? Did you see that Direxion suddenly changed the ratios on a bunch of 3x down to 2x on March 31? Scary stuff to me.

https://www.marketwatch.com/story/direxion-is-accelerating-t...

In 2009 a leveraged ETF trading at $100 ended up paying about $85 as a dividend (I think because it was excess profit by being long vol.) That would be an overnight tax hit if you are in the wrong type of account. I don't recall which one it was, maybe FAZ?

mcgoo | 6 years ago | on: Amazon is shipping expired food, customers say

If you create a listing that competes with someone else’s high volume product you will get fake reviews claiming the product is expired. Multiple times this has happened on a brand new listing with no sales, before the product even arrives at Amazon. Expired is one of the go-to false complaints.

In my experience Amazon reliably push expired product back to the seller, at least using the dates that were declared by the seller. This does not stop a seller from claiming what they like, I suppose.

mcgoo | 6 years ago | on: Ask HN: How Do You Sleep?

I tried maybe 5 different kinds of mask until I found what worked. Interestingly, according to the supplier I get stuff from, the masks are all pretty much compatible between manufacturers so there is a lot of scope if mask discomfort is the problem.

The future earnings have huge uncertainty to them. A company with a $50 stock price might have $5 per share worth of cash in the bank, (which is something you can actually observe.) The other $45 represents expected future earnings. If the stock pays out a 50c dividend, the stock now has $4.50 per share in the bank and the $45 expected future value is unchanged.

mcgoo | 10 years ago | on: Ask HN: What's better for long-run productivity: caffeine or no caffeine?

This. For me, exercise is the gift that keeps giving.

Caffeine works for a couple of days and then becomes a requirement. Any ongoing benefit is difficult to discern.

There are other things that make a huge difference to productivity for me :- - have a plan for the day - make sure to work on stuff that is actually important - look back at the day and see where time was wasted or I went off track and think about how to do better next time - stop working at a fixed time (with a little leeway if I am really in the zone and enjoying it.) This leaves me excited to get to work in the morning. Scheherazade effect :-)

mcgoo | 11 years ago | on: Ntimed – NTPD replacement

The jitter introduced by garbage collection in a go implementation could well be significant, even with the new "never pause the mutator for more than 1ms" guarantee.
