Also important to note that this is Starship Serial Number 8. If it has an "accident" it's good to know that there is actually a Starship SN9 that has just been completed at the manufacturing base a couple km from the launch site, standing by to take its place and try again.

Then there are two more vehicles abou 50% done - just join the tanks and add the pointy part in the front.

And parts have been spotted assigned up to SN16!

So this is really no ordinary space program where you prepare for years to launch a single super expensive rocket and then deliberate for months or years what went wrong and how to fix it.

No, they built the best rocket engine ever, attach it to glamurous 50s SF rocket built from stainless steel (and random Falcon 9/Dragon/Tesla parts) in a marsh and then launch and make more until it can go to space cheaply and reliably.

You might also consider working in a research lab at your university, where you are likely to find some harder problems.

My recommendation: do the homework - you'll presumably breeze through it if you have mastered the material. If not, it will be a good refresher.
In summary, for normal people, taxes in the US come at federal, state and local levels.

1. Federal:

a) Income tax of 10% on income over around $12k (single) or $24k (married) up to 37% on income over $518k (single) to $622k (married). Capital gains tax is at the same rate for assets held less than a year but up to only 20% for assets held more than one year.

b) FICA, a wage tax. You pay for 7.65% for social security and medicare/medicaid on all wages up to around $133k and 0% above that.

2) State. This varies widely. Some states have no income tax, some states have income tax rates of as high as 13.3% (California). Most are around 5%. Each state has different deductions and rules. Capital gains is usually included in this. Most states (but not all) also levy a sales tax of around 4% to 8% on retail transactions.

3) Local. Most local taxes are in the form of property tax on real estate. The rates vary from around 0.5% to 2% of property value. Some towns levy a separate sales tax on top of a state one (if it exists). The real estate and sales taxes are used to fund schools, police, fire, etc. Many municipalities also levy fees for water, trash, etc. Some cities also have an income tax (for example NYC).

To give you an idea of just how complex it is, the US has approximately 11,000 different sales tax jurisdictions. And it's not just a matter of rates. What is taxed and in what context varies. For example, in NYC, food from groceries is not subject to sales tax. But food from restaurants is. Unless, I think the restaurant has no more than some minimum of seats and you orders your food to go. Some sales taxes can also vary by date (i.e. sales tax during summer, but otherwise none). There are also occasional sales tax "holidays" where no sales tax is charged.

Unsurprisingly, tax lawyers and accountants make good money in the USA :-)
Which is ironic, because this is the kind of automation they've been building into planes for years and consequently air travel is safer than it's ever been.

737 Max fiasco notwithstanding - it's worth mentioning that MCAS had nothing to do with flying the plane, only making it feel more like the 737NG to its human pilots
LH2 is way less dense than RP1 though, so you’d need a significantly larger fuel tank to carry the same amount of fuel.

Hydrolox (LOX-LH2) is about 30% more power than Kerolox (LOX-RP1), but is about 3.5x less density.

Source: https://en.m.wikipedia.org/wiki/Liquid_rocket_propellant#Bip...

Hydrolox - Ve: 3,816 d: 0.29

Kerolox - Ve: 2,941 d: 1.03

If you were wanting to optimize for high specific impulse, it seems LOX-LH2:Be or a fluorine based fuel is the way to go purely on the numbers (not accounting for cost or stability).
Not arguing the air quality, just wanted to point out how stupid it is to argue for something just because we did it for thousands of years.

They use pintle injectors in the Merlins, so that does move as well (though only a short distance) and is likely what makes them so throttleable.

I think it is the height on human ignorance to believe that intelligent life could have only evolved on this tiny dirt ball. I am convinced it has to exist somewhere at sometime.
It doesn't show people upstairs in that video. Even if they were, they were doing it to clear the corner and then lowering the weapon after identifying them as non-hostile (or no person at all since they aren't on video).
If you fire this cop, they'll hire a new one, and put them through training that says that everyone might be armed and they're authorized to use force when they think they're in danger, and they'll continue sending cops out to raid people's houses for crimes where there's absolutely no evidence the suspect has ever even thought about being armed.

This cop almost certainly was in fact willing to destroy whatever he pointed his gun at and whatever might be behind it, because that's how he was trained.
You can have mathematically meaningful sub-types of a GA multi-vector that also map nicely to some basic shapes or transformations.

Generally speaking, a multi-vector can be broken down by which "grades" it contains. There are subspaces like "all even grades" that are closures under all basic operations.

If I remember correctly, the "even subset" of a 3D GA multi-vector is isomorphic to the Quarternions, which is why they turn up so often in 3D graphics libraries.

But think about how messy this is! These 3D libraries are blending together subsets of vaguely related algebras that are not "compatible" from a type theory perspective and so they're forced to convert back-and-forth. It's like mixing Unicode UTF-8 with Latin-1 byte strings. If you squint, it looks like one is the subset of the other... but not really.

With a pure GA-base library, the "rotation interpolation" functions would use the "even multivector subset" type, and be totally compatible with the rest of the library. It's the same type definitions, just with different parameters. This would be like using UTF-8 Unicode throughout the program, but having the ability to define a string-based type that only allows the "Basic Multilingual Plane".

> For a class of 15, 1 teacher is sufficient

No, it's not. And we have LOTS of research on that.

Some young child always has a problem. When that happens, the attention of a teacher is completely tied up. You need two so that the class can keep going.
> The company's codebase is not your space

That’s one possible way to look at “the company’s code.” Another one is that you’re in “that” code six (or more) hours a day and it’s usually written by someone else. So if everyone codes to _their_ comfort, there’s a likelihood that no one is comfortable in the code ever. I find code style standards that a team as a whole has compromised upon (aka consistency) a reasonable approach to “average comfort.”

Signils, Bluetooth Manager
Hi,

We've successfully launched our Android mobile app, Signils.

Signils is an app that gives users a visual way of managing Bluetooth devices. Users can see icons or images that represent their devices and enable lost device tracking with a slide of a toggle button (1 of 3 ways). It also helps identify potentially dangerous devices during the Bluetooth scanning and identification processes. There's also a manual location tracker: simply type in where you keep your devices so you don't lose track. We're looking at adding the ability to manage Wi-Fi connections next.

We're getting about 1,100 downloads per day and hit 83,000 downloads today since we first made it available on 3 September.

Not all tech employees wanted to live in SF and commute for 4 hours a day. Cities like Palo Alto and Mountain View had severe restrictions on building housing. So SF, Oakland and San Jose took the burden of housing the techies. Naturally people here got angry. But instead of focusing the anger in solving problems it was extremely common for people I meet to loudly complain about tech workers - bars, parties, nextdoor and side walks were full of hate messages. I left the city 3 years ago and I completely understand how frustrating it is.
Why? Because regardless of the legalities here she is doing good work in a state that is committed to hiding the truth from residents.
> It's very impressive and I don't know why having software optimized to the hardware is a demerit point.

It definitely isn't! The point was that we should consider both software + hardware together when praising the performance of the M1. That is why comparing the M1 with an Intel / AMD processor is like comparing Apples to Oranges. :)
No. This isn't a software company.
The vehicles, sure. But they get orher, simple equipment too.
This just came up a bit ago in another thread. RBG is so good. Like I did a while back I'll mention that that work is the reason I could write this Ruby svg viz library https://github.com/SpeciesFileGroup/waxy and it be a fun, rather than painful process.
I think you're severely underestimating the impact of California's investment in education. UC Berkeley and Stanford (private, but accepts state research grants) are top institutions which had for decades attracted some of the brightest minds (professors and students) to the area. These people helped shape the field, from early work on the ARPANET and Operating Systems to the Big Data and AI innovations of today. The expertise is passed on to students which creates not only a highly talented labor pool, but also trains the next generation of innovators.

Considering this concentration of talent, I think it's no surprise that the Bay Area is a hub for innovation, and the impressive list of companies founded by Berkeley [1] and Stanford [2] alumni is a testament to this. The concentration of talent is the environment that attracts funding and VCs, and will ensure that the Bay Area will remain the place to be in tech.

And Seattle, your "perfect counterfactual", has University of Washington, another state-funded top institution.

If you have a gas range or oven (which I wish I did since they are basically banned in new construction) definitely turn the hood fan on high before turning on the gas and leave the fan on until after you turn it off. Otherwise your kitchen will fill up with methane, nitrogen oxides, carbon monoxide, and other pollutants. (Some when you turn the burner on, some during operation, and some when you turn it off.)

"the investigators estimated that, during a typical winter week, 1.7 million Californians could be exposed to CO levels that exceed standards for ambient air, and 12 million could be exposed to excessive NO2 levels, if they do not use venting range hoods during cooking."

https://ehp.niehs.nih.gov/doi/10.1289/ehp.122-A27

Also pilot lights are apparently responsible for about 30% of methane emissions from older gas appliances. So ventilate your house or switch to electric ignition.
Ah, I wish I had come across this two weeks ago!

I've been doodling with Processing and was working on hexagonal Truchet tiles. (basically random tiles that have paths connecting to any random tiles next to it, with hexagons as tiles instead of squares)

I ended up having to figure out some of that stuff again, in particular the coordinate system inside each tile so that I could deal with integer coordinates and translate them into the right fraction of the radius.

It was fun to figure out what I needed, so I don't regret it :)

And I am also planning on doing something with cubes, so this page will come in handy.

Thanks for sharing! I love how it covers all aspects of the problem.

Another major issue we have with policing in the US (aside from the people who are only there as a power trip) is that one group with little variation in training is sent in for everything from jaywalking to armed robbery.

The odds of any random police officer encountering a situation where they are going to be truly in harms way are lower than the odds they use excessive force against a cooperative person. It's horrific.

Being a pizza delivery driver is twice as dangerous as being a police officer.
Good point. The managers would probably give negative feedback to people that took more time on their calls in order to try to help the customer better.

Part of the reason to make promises is that they are legally enforceable:

When I started an organization which was taken over in a rather hostile way, I was very careful to make a bunch of legally-binding promises before the takeover happened, to help prevent it from becoming too evil.
You touch on the primary flaw of "spend the money here on Earth" argument.

Money spent on space programs IS spent here on Earth. The money paid to engineers and fabricators and for raw materials goes to pay for house payments, durable goods, food and taxes of the individuals working on these projects. And those payments create jobs delivering these services, which benefits an ever increasing number of people.

It's not as if dollar bills were litterally burned to provide rocket thrust.
I thought that the link layer has built in mechanisms for detecting and correcting errors. Can someone ELI5 what's going on?
I'm convinced too - somewhere in the near-infinity of space, sometime in the near-infinity of time. But the chances of intersection just seem so staggeringly low... even if both parties were actively looking!

As for evidence: I just needs something as tangible as the covid vaccines... some proof that makes it believable it's not just some company trying to get research dollars.

I remember being really excited 25 (25!) years ago when a very intelligent professor I knew convinced me that evidence was plentiful (verified by high-ranking military) but it had to be kept under wraps as not to cause a public panic: they'd dole the information out slowly.

That's a tired story now. So I'd just need evidence more than just "trust us, we're high-ranking".
I believe it exists already.
It's informative, but if everyone used this logic, nobody would improve. Suppose all nations on Earth had particulate level X, which instead of 12,000 deaths, caused 10 times as many.

We could pat ourselves on the back for doing great compared to our peers. That's not how one innovates.
This is very true(personal experience). It’s not just in the academy it’s in every training course. All it takes is a jittery Rookie and things go wrong quick.
"Secret filtering" is buggy, broken, stupid, misleading, and just plain wrong anyway.

1) If you can cause it to be run on arbitrary code then you can cause it to reveal the secret. Even if the only output you see is a pass or fail.
2) If you can't cause it to be run on arbitrary code, then why do you need to see any output?

Does the IRC bridge work reliably for you? I tried experimenting with Matrix today, I could make it to join #freenode_#xmonad:matrix.org but any message I sent didn't go through to the IRC side. When I then joined #irc:matrix.org it seems several other people were reporting this not working lately.

To make this experience even less amusing, I then tried to join #xmonad:matrix.org, assuming it's the matrix equivalent of #xmonad on freenode, but it just said I'm not invited and that was it.

Can't say I'm impressed. :-(
Doing the landing swing move and then stopping the swing with the rocket engine seems dicey to me. The timing on those firings need to be incredibly accurate.

We moved into our house a couple of years ago. It had a nice gas range that we were pleased was in the home.

When we moved in, we noticed this specific "gas particulate" smell throughout the house whenever we'd use the stove. It wasn't leaking gas, but rather this smell I associated with dirty burning or something. The other times I've smelled it have been in propane space heaters for outdoors.

We replaced it with an induction range and have been completely happy with it. Heats amazingly fast, no burner to burn things, no emissions in the house, we love it. I never want to own another kind of range again.

In the vast majority of cases, the police choose which situations to enter and how to engage.
Im an SRE, the architect decided some time ago that we needed a mongodb db deployed in our cluster. I fought against it at first, as it is best to get a managed solution instead. The dev's position was, "how hard can it be to operate a database? You can use a kubernetes operator now"

This is why I settled with a PS4 last year. Even on a Linux PC, I would feel "dirty" with games and steam installed, and I can't afford a PC exclusively for gaming. A PS4 costs 300€ and runs Skyrim, so I am quite happy. I am also speculating that the PS4 will become completely owned by the community and ultimately runs Linux without anything missing.
