So her recollection is that she was in the house to view Lincoln's funeral procession. She didn't, because she was three and got scared, but it was still an event she was a part of.
Even if she didn't remember whether Teddy was standing at that window at that time, she probably knew that she at Teddy and his brother were at the mansion for the event.
So we have the Roosevelt mansion, knowledge that not many boys would have been allowed to be in that window, and confirmation that Teddy Roosevelt was there watching at that time.
I was working at a crawling-based business around that time, and we thought it was because bandwidth contracts at that scale were symmetric, so the idea was that Google could serve video for ~free because they were crawling the whole Internet constantly and serving extremely light weight pages of ten blue links.
Actually, the last time I looked into it, if you grow 2 acres of corn and 1 acre of soy, and feed it to chickens, you get out a similar number of calories (and more protein?) as 3 acres of soy.
Corn produces something like 15M calories per acre, soybeans like 6-8.
When you feed those 36M calories to chickens, you get back 12M calories of chicken, which is actually less than 6 x 3 = 18M calories for the soybeans, so I'm misremembering something (maybe it's just an equivalent amount of protein? maybe chicken feed is a 3:1 corn:soy ratio?) or was just wrong.
Basic security hygiene in the modern world is "assume your employees can be a threat", either because they're incompetent ("I accidentally deleted the shared spreadsheet, I thought it was my copy"), malevolent ("I will show them all!") or compromised ("I clicked a link in my email and now my computer is slow.")
If you aren't designing your systems to be robust against insider threats, they will fail.
(If you design them to be robust against insider threats, they will probably also fail, so you have to be constantly working to understand how to limit the consequences of any individual failure.)
The simplest recipe for writing "almost bug-free" software is:
1. Freeze the set of features.
2. Continue to pay programmers to polish the software for several years while it is being actively used by many people.
3. Resist adding new features or updating the software to feel modern.
If you do that, your program will asymptomatically approach zero bug.
Of course, your users will complain about missing features, how ugly and ancient your products look, and how they wished you were more like your buggy competitors.
And if your users are unhappy, then you probably lose the "used heavily by a lot of people" part that reveals the bugs.
There is no system without exploitable breaches, whether technical or social ones. The biggest point is, who have the incitives to exploit them, how much resources it costs to run a trial, how much resources do they control and are they ready to throw at attempts.
I am not an expert, but my understanding is most funds don't change allocations immediately, but it would be part of normal rebalancing, e.g. VOO and other indexes that track the S&P500 do it quarterly
They all smear the purchases and sales from index changes, but I don't think they publish on what timescale. Most funds try to minimize tracking error. There are funds that take this to a different level. When a stock is added to the big indexes, it tends to do poorly over the next year, and on the flip side when a stock is removed it tends to perform well. Dimensional funds have automatic rules to take advantage of this type of thing. There are other companies that have funds of this style, but overall they are much less widely used than the big index funds from vanguard, blackrock, state street, etc.
S&P500 held fast to their rules on consecutive quarters of profitability and forced TSLA to meet them (must be profitable in qX + sum to net profit over the past year). If they hold to them this time, SpaceX would need to be profitable over a year while public to enter the index.
They have instituted rules and gone back on them eventually (most notably for several years they had a "no going public with different classes of voting shares designed to allow control forever, if IPO is after today" rule that they eventually dropped) but they are generally pretty good about following rules.
1. Elon is a genius, a real world Tony Stark.
2. How dare you! You're just jealous!
3. Ok, regardless, he's done more to advance EVe and space travel than anyone else alive.
4. Oh God, he's going to cripple US development of EVs and rockets, isn't he?
5. Eh, Mars was never happening in my lifetime anyway.
Correct me if I'm wrong, but I remember stage 1 being maybe 2011. There were plenty of Musk critics back then, as there are now, but they seemed to have been completely wrong on pretty much everything. I remember people saying he was a charlatan whose technology would never work and even if it did it would never get mainstream market penetration. I feel like you would have smugly chuckled if anyone told you the following things that are true:
1.) Tesla cars will be ubiquitous on American roads
2.) The best selling model of car globally would be a Tesla
3.) Most cars would be made in the US, yet still be price competitive with foreign competition
4.) SpaceX rockets would be re-used multiple times per week
5.) SpaceX's launch business is highly profitable despite lowering prices to less than 10% of what they used to be
6.) SpaceX launches more mass to orbit than the rest of the world combined
1. Tesla has sold ~2.5-3M cars since 2017 in the US. There’s more than 200M cars on the road in the country. Ford has sold more F series trucks in the last 4 years than Teslas have been sold ever.
2. The only reason Model Y is the best selling car in the world is because 3/4 of the sales come from the US and Tesla only sells one model of SUV. Other brands sell many different variants and multiple models in the same category across the world.
3. Teslas are not at all competitive in other markets. BYD is eating their lunch.
4-6. Yes, but the global market for space launches is projected to barely touch $30B by 2030. Global competition for this market is only getting fiercer with multiple US startups, India, China and more recently France.
Now let’s talk about the failures.
1. Nueralink
2. FSD
3. Roadster
4. Cybertruck
5. Hyperloop
6. $2T in Doge cuts
7. Robotaxi
8. Starship
9. Tesla Semi
10. 4680 battery
11. Boring company tunnels
12. Bots that were going to disappear on Twitter
The list is very long when you actually include all the data points.
Tesla was founded by different guys, Musk just forced them out.
SpaceX is indeed very cool, but not because of Musk. He just put his name on everything that might have been cool, even if dumb (remember Hyperloop? I always wondered on what grounds PR teams associated Hyperloop with Musk, as the idea was very old, and he didn't give it any money -- what relation he even had?)
I've heard from SpaceX insiders that they don't like the guy very much. SpaceXers do cool stuff, and then Mr. Musk comes in and makes everyone believe it's he himself done all that.
If you're not getting downvoted at least some of the time on HN you're doing something wrong. I've caught plenty of downvotes myself for arguing that Mars was never going to happen and is just a recruiting tactic for SpaceX to hire idealistic young engineers and pay them sub-market wages because the dream of Mars is part of their compensation.
All the hardware they've actually invested in, including Starship, is in fact foremost for launching satellites into Earth orbit. Starship in particular is optimized for this.
Self-driving is a thing. Full self-driving, commonly known as "level 5 autonomy", has been claimed for over a decade. These claims have been made so many times it has a dedicated Wikipedia page!
So basically we don't have full self driving, not because it doesn't work but because the regulators haven't approved it yet? Seems a little misleading to claim this is some failure on the part of Tesla's technology
But those levels are kind of bullshit. If a car is autonomously driving but needs an attentive driver in the seat for legal reasons you're stuck at what, level 2? Even if you never actually need to override/intervene?
Teslas running the latest hardware (manufactured 2023+) and software are actually nearly there, IMO. I used it for two months and never needed to intervene. It's not perfect yet but I believe it actually drives better than most people now.
However, the millions of Teslas on the road with older hardware are absolutely useless in comparison where you will need to intervene a lot. The latest FSD software only works on the latest hardware so these older cars are stuck on either old FSD versions (which are proven to be bad) or get slimmed down versions to fit lower specs (which we know wont be as good). It's unsafe and they really should disable it for all of the older vehicles and issue refunds for people who paid for FSD.
There are statistically around 15 women AFAB with XY chromosomes in the NCAA by those numbers (assuming no correlation between Swyer syndrome and athletic performance).
There are currently around 10 openly transgender women in the NCAA.
Even if she didn't remember whether Teddy was standing at that window at that time, she probably knew that she at Teddy and his brother were at the mansion for the event.
So we have the Roosevelt mansion, knowledge that not many boys would have been allowed to be in that window, and confirmation that Teddy Roosevelt was there watching at that time.
