pacificmint··on Militaries are scrambling to create their own Starlink
> you can fire a THAAD at a Starlink satellite as well.

You can fire a THAAD at one Starlink satellite, but probably not at 8000 of them.

For comparison we’re currently producing THAAD interceptors at a rate of 96 a year (though Lockheed is aiming to increase it to 400).

pacificmint··on Uber Found Liable in Rape by Driver, Setting Stage for Cases
I mean, it’s not quite that simple, is it? Did they do everything they could to make drivers and passengers safe? Or did they put profits over people’s safety?

From the article:

> internal company documents […] showing that Uber had flagged her ride as a higher risk for a serious safety incident moments before she was picked up. Uber never warned her […]

Uber actually had a whole project that produced systems that determine the risk of incidents happening. Could they make rides safer but chose not to? That’s at the core of these lawsuits.

pacificmint··on Two billion email addresses were exposed
I agree. I wish it would tell me the password, there is a good chance I could identify the service that it came from based on the password. This way it doesn’t feel that useful.
pacificmint··on German government comes out against Chat Control
> but a leading member of the parliament

I think ‘a leading member’ is underselling it a little. He is the “Fraktionsvorsitzender”, which is comparable to the majority leader in the US Senate.

pacificmint··on Poison Pill: Is the killer behind 1982 Tylenol poisonings still on the loose?
> it's sold in pill sheets (is that the name?)

They are often referred to as Blister Packs.

pacificmint··on NZ airport to remove Hobbit-themed eagle sculptures
> Made of polystyrene and with an internal steel skeleton,

They weight 1.2 tons total. If they are made of polystyrene and steel, it stands to reason that a significant part of the 1.2 tons is contributed by the steel.

pacificmint··on Old Soviet Venus descent craft nearing Earth reentry
The Air Force never had a space shuttle, though NASA flew missions for the Air Force and the NRO.

But at this point none of the remaining shuttles are in an operational state.

Maybe you are thinking of the X-37 which is operated by the space force?

pacificmint··on Widespread power outage in Spain and Portugal
They’re called Coffman engine starters [1].

Random fact: Those starters are a plot point in the 1965 film The Flight of the Phoenix, where the protagonists are trying to start a plane that’s stranded in the Sahara, but only have a small supply of starter cartridges left.

pacificmint··on Dirty tricks 6502 programmers use (2019)
There was also that 4k block of memory at $C000. It was in between the ROM blocks, and by default it was totally unused.

Basic couldn't utilize it, but in assembly it was a great area of extra memory, and you could use it without even switching the ROMs off.

It stands for "Cover Your Ass".

Wikipedia explains it as "an activity done by individuals to protect themselves from possible subsequent criticism, legal penalties, or other repercussions, usually in a work-related or bureaucratic context."[1]

pacificmint··on Why a plane turned around when a passenger lost a phone midflight
When people say “Lithium batteries” in this context, they mean lithium-ion rechargeable batteries.

AirTags contain lithium primary batteries, which are a totally different thing (other than both containing the element lithium).

Lithium primary batteries present no more a risk than alkaline AAs. Probably less.

pacificmint··on Ask HN: How did the internet discover my subdomain?
Case in point: When Daimler and Chrysler merged, they had a law firm (with no other ties to either company) register the DaimlerChrysler domains weeks before the merger was made public.

I don’t recall if anybody noticed before they went public, but as this thread shows, today it would be noticed for sure.

pacificmint··on Air-Traffic Staffing Rules Tightened at Reagan Airport After Fatal Crash
I think it might be a typo that was supposed to say VIP Movement.

I've heard ATC use that term when Air Force One was in the area. They won't say who specifically is there, or even that it is AF 1, but instead just say that air space is closed "due to VIP Movement".

I don't think it means they care more about safety when a VIP is around, rather that a VIP movement might shut certain other operations down, which increases the overall workload for ATC.

For example they sometimes (or always?) stop all ground traffic from even moving while AF 1 is taxiing, landing or taking off.

pacificmint··on Jeep owners fed up with in-car pop-up ads
You know how there is the cliche that old people are always ranting how everything was better in their day?

Personally, I'm not quite there yet, but the older I get, the more I see their point...

pacificmint··on Costco’s butter recall, explained
Of course milk doesn't mean milk anymore either, now that we got oat, almond and soy milk. Along with less common alternatives like coconut, hemp, rice, cashew and macadamia milk.

The dairy industry is actually pretty annoyed with that and tries to get the rules changed so those beverages can not be called milk.

pacificmint··on GPTs and Hallucination
If you ask the model what the color of grass is, and it answers blue, then that would indeed be false (or maybe a lie). I think most people wouldn’t call that a hallucination.

But if you ask it for a court case, and it makes up a whole false case file with fake names and fake facts and everything, then calling that ‘false’ seems to be an understatement. Hallucination seems a good label for that kind of thing, imo.

pacificmint··on Boeing's Starliner proves better at torching cash than reaching orbit
> cost 3x the amount to develop

With cost plus contracts that’s unfortunately a feature and not a bug.

I think Boeing has just been unable to pivot to behaving differently for fixed price contracts, which is not surprising given corporate inertia.

pacificmint··on Pipes: A spiritual successor to Yahoo Pipes
I realized at some point that when people at work draw on whiteboards it usually ends up as boxes and lines between boxes.

But after thinking about it, it feels natural, because usually we talk about "Things" and the "Connections" between them.

Could be a companies org chart, a family tree, a network diagram, abstract things like processes. It's all "Things" and "Connections".

Maybe that's why graph theory has so many applications. Because at the end, it's all just graphs with vertices and edges.

pacificmint··on Will we ever get fusion power?
> Germany, one of the most progressive nations on the earth, went and shut down all of its nuclear plants as a knee jerk reaction.

Anti nuclear sentiment had been building in Germany since at least the 70s. Then Chernobyl happened in 1986 and it got even stronger. It was part of what propelled the Greens into the administration 1998.

That administration reached an agreement for the nuclear exit in 2000 and the first plant went offline in 2003.

Merkels cabinet tried to extend the planned runtimes for the remaining plants, and it was that extension that was rolled backed after Fukushima.

Now, you can think that it was a big mistake, but it certainly was not a knee jerk reaction. It was a decision that was 50 years in the making.

pacificmint··on When Companies Ask for Your Social Security Number, Try Saying No
That’s right.

You can use a number as a unique identifier for each person that everybody stores. You can also use a number as a secret code to authenticate yourself.

But you can’t use the same number for both purposes.

pacificmint··on Tesla retreats from one-piece "gigacasting" manufacturing process
The idea is to cast much larger pieces than before. Traditionally it might have been dozens of pieces. Tesla is currently doing the underbody in only three pieces, and they were trying to cast it as a single piece.

Does that warrant a new word? I don’t know. But there is an innovation here in how it is manufactured.

pacificmint··on Watch a 7k-LB Rivian R1T Destroy a Guardrail in Eyebrow-Raising Test
It would be common to say 7000 pounds. It’s less common in everyday usage to say 7k pounds.
pacificmint··on Passenger flight flying over Pacific reaches 822 MPH in jet stream
An imperial mile is 1,609 meters. A nautical mile is 1,852 meters.
pacificmint··on A drought has forced authorities to further slash traffic in Panama Canal
Isn’t that how all locks work? Or at least most?

I’ve always assumed the energy cost to pump the water would make it cost prohibitive, but I wonder how it compares to rerouting ships or moving containers over land.

pacificmint··on NERV Disaster Prevention
The government didn't call it Star Wars, they called it SDI. Some lobbyists used that term and they were the ones that Lucasfilm tried to sue.

The lawsuit was dismissed, btw.

> On November 26, 1985, the suit was dismissed by Judge Gerhard Gesell of the United States District Court for the District of Columbia, on the grounds that the lobbyists' use of the mark in a noncommercial and non-trade context fell outside the jurisdiction of trademark law. [1]

pacificmint··on Modern iOS Navigation Patterns
Case in Point: I really like Costco, but if I ever cancel my membership then it is because of how they seem to reshuffle significant parts of the store every few weeks.

I don't know if they think I will buy more if I run around for fifteen minutes looking for something, but man it's annoying.

They probably think of it as 'increasing engagement'. To me it's just wasting my time.

pacificmint··on Could we stop Yellowstone from erupting with a geothermal power plant?
Plus you’d take a great step towards solving our energy problems.
pacificmint··on Sqids – Generate short unique IDs from numbers
> you can tell the growth rate of the company.

You can even do this when you don’t know the exact interval by using probabilities. The Allies used this method to estimate German tank production in World War II by analyzing the serial numbers of captured or destroyed tanks.

This is know as the German Tank Problem [1]

pacificmint··on Training for one trillion parameter model backed by Intel and US govt has begun
If I ask it what color an orange it and it says blue, that would be wrong.

If you ask it a question and it makes up a completely fabricated story, like for example the case files in that recent legal case [1], then saying it was “wrong” doesn’t really seem to capture it.

Calling it a hallucination is a great analogy, because the model made up a plausible sounding, but completely fabricated story. It saw things that were never real.

pacificmint··on OpenAI's employees were given two explanations for why Sam Altman was fired
Employment in California is ‘at will’, which means they can fire him without a reason.

Wrongful termination only applies when someone is fired for illegal reasons, like racial discrimination, or retaliation, for example.

I mean I’m sure they can all sue each other for all kinds of reasons, but firing someone without a good reason isn’t really one of them.
