Good explanation.

A simple GPS receiver will have a generic mathematical model for the ionosphere and use that as a good guess. More advanced ones can measure the delay directly.

The ionosphere affects different frequencies differently, so the GPS satellites transmits additional signals at different frequencies. By measuring the phase of these signals (L1 and L2), the math can be done to get a better estimation of the delay caused by the ionosphere between each satellite and the receiver. Those are the dots we're seeing on this animation. (GPS also uses the L2 signal to transmit encrypted information that lets military receivers get a better fix than civilian receivers).

I love Go but I must confess I was a bit skeptical when I read the article:
1. In my own experience, firefox is usually faster than chrome at executing wasm.

2. I'm not a rust programmer but the performance of the rust implementation a bit surprising compared to tinyGo.

Still, tinyGo is very impressive. Very glad we have this project.
Too bad almost all containers rely on bridged networking and different ports. Why not just bind to 127.0.x.y, where x is the project number, and y is the machine number. That way, you can just use default ports
What I notice: We guarantee a monopoly for visa and mastercard, ensure that transactions cost 3-4% for everyone, and make sure that money requires days to move between accounts.

The state of transaction processing in this country is hot garbage. I'm not claiming that crypto is the answer, but I sure as hell don't think our society has arrived at any sort of best solution. I'm personally fine with a lot more "crime" (aka transactions you personally don't approve of) if it gets us a better financial system.

In one word: bullying. However, I don't think we should stop schools. In my case, homeschooling would have prevented a lot of suffering, but that didn't happen.

Another thing I hate is how school and teachers are glorified all the time. Sure, I had some great teachers. I also had terrible ones, and the final balance is negative. But they can't accept that, so in my country you need to have a reason to homeschool kid, and ask the administration.

Someone asked what "school" is here, for me it would be everything up until high school (included).

Notice even in the thumbnails on that page, the car has a much taller flatter nose than a comparable car would’ve in the early 2000’s.

It does look like modern SUVs are less safe than the SUVs of old, however. I guess they’re getting too big. If you look at the SUV that Fifth Gear was testing with in the early 2000’s, it basically counts as a “small compact” in modern USA. https://www.iihs.org/news/detail/new-study-suggests-todays-s...

As someone else mentioned, the biggest problem may be turning visibility. This combined with right-turn-on-red creates a uniquely American safety issue.

Apparently one major issue with fast food is the hyperpalatability.

For example, when I visited my family in the states, I ate two double cheeseburgers at a fast food joint at 1000+ calories per burger, and I figured I could probably eat two more in that sitting without issue.

In other words I ate 2000+ calories in a few minutes and could have kept going. Even one burger has more calories than I eat in a single meal.

Meanwhile, I couldn’t eat 15 medium sweet potatoes (1000 calories) in one sitting.
You can get them to remove a page without too much difficulty.

It may be more difficult to get them to remove a subset of the content on of every capture of https://web.archive.org/web/20220000000000*/https://news.yco...

That becomes even more difficult if you want to have them find (and remove) all comments from all captures on all pages for a particular user.

Noting that you don't have authoritative control over HN, archive may be a bit reluctant to have {random person} asking for all of the comments that {random account} made on all the captures to be removed.

If archive was able and willing to do that (remove content from a random account as requested by a random person), I believe that it would be abused much more than it was used.

I’ve been working at a big tech company (first job out of college) for the past year and so and I’ve been considering changing jobs for several reasons I won’t get into but one of them being that I feel I could be learning so much more in a startup.

My concern with this is I don’t want to become the person that jumps from company to company that never really properly learns what they’re doing.

I’m trying to maximize for learnings, not money since I’m privileged enough to not have to worry about it.

As mentioned in the post, git notes can be used for code review, and I wish code review systems would have but a front end system that end up being encoded into the source control itself: think about all the times you had to find the first commit that introduced a specific line then trace it back to the code review that approved that change. It can surely be streamlined even when external to git, but since it's coupled, to me it makes sense that it should reside together and be available offline just like every commit.
In fact some plumbers still do lead work. Lead sheet roof flashings are common in the UK. Roofers can beat it into certain shapes, but if you need something more complex you would get a plumber to weld it for you.

I learnt to lead-weld (with oxy acetylene) in the past and found it very satisfying...
Maybe in a secondary sense the type of automobile is part of it but also I don't know why you are saying there is "increasingly poor visibility". There have been trucks and SUVs for decades now as well.

My belief is that very bad habits were created by the empty roads in 2020 that made people start speeding. A plausible case can be constructed around this theory based on evidence. A lot of people are anecdotally familiar with this as well.

Traffic data indicates the higher death toll was related to higher average
speeds in conjunction with more of those on the roads driving under the
influence of drugs and alcohol and a slight decline in seatbelt use.[1]

Speeding increased after the pandemic lockdown.[2] There also appears to be an increase in road rage incidents.[3] So far in 2022 NHTSA says that there is an increase in road deaths for early 2022.[4] One theory that could explain the sustained increase is lower levels of traffic enforcement.

I was totally shocked by the shape of truck grills last time I visited Canada. The standard F150-esque chassis used for all sorts of commercial vehicles is fronted by a huge slab of steel. And those things are everywhere - it's not just the obvious "manly truck lovers", but all sorts of commercial vehicles where it's totally unnecessary. In Toronto the parks service are all driving around in those trucks. As the parent of a 2 year old, they are SCARY - the blind spot in front must be massive.

In Europe we mostly use van derived chassis for commercial vehicles. Ford Transits or Fiat Ducato (Dodge Ram Promaster in NA). They seem to be able to serve the same purpose without having terrifying blind spots.

> From the damage that was caused, it sounds like there are no “hardware” fuses built into this system either. That alone should be cause for regulators to take the product off the market.

No, it just sounds like inverter, to which there are two devices connected, one which suddenly draws a lot of current (like starting power tool, possibly the one pictured in the article) and an "electronic device" with switching power supply. When the large current draw happens, the inverter tries to compensate which results in a lot of power transmitted over higher frequency (several tens kilohertz rather than usual 50 Hz). That higher freq bypasses input cap and fries switching power supply.

Matthias Wandel did a video about his own problems with portable battery setup, which did the same: https://www.youtube.com/watch?v=c1QSn3i_IEo.

This inverter is just not suitable for powering different devices. ISTM those different "offgrid" technologies are just not ready for prod.

The first 2 meanings of plumb from the site you link is:

https://etymology.en-academic.com/27820/plumb

plumb
plumb
{{11}}plumb (adj.) "perpendicular, vertical," mid-15c., from PLUMB (Cf. plumb) (n.). The notion of "exact measurement" led to extended sense of "completely, downright" (1748), sometimes spelled plump or plunk.

{{12}}plumb (n.) c.1300, "lead hung on a string to show the vertical line," from O.Fr. plombe, plomme "sounding lead," from L.L. plumba, originally plural of L. plumbum "lead," the metal, of unknown origin, related to Gk. molybdos "lead"

Neither have anything to do with pouring molten lead. Only measuring the vertical.

The purpose of finding the vertical is to determine the horizontal in installing sloped pipe.
I can speak to this a little, as I have the same aversion to the JVM. Despite wanting to get into Clojure multiple times, I always get hung up on getting going with it. How do I install Java? Is this the "right" Java? How do I now install Clojure? Which project management thing do I use? There's this Leiningen thing but also this new Clojure CLI. Then it comes to IDEs, and they all work rather differently.

The first time I tried Clojure, I tried with Leiningen, but it dumped literally hundreds of lines of Java stack traces when something went wrong. So I stopped.

As a comparative example, how do I install F#? Well, you install the .NET SDK, and then you get F# automatically. When something goes wrong, I get good error messages that are tailored to F#.

I think it's a little misleading to ask "why do you care about the JVM?" because the answer is that "Clojure makes you care about the JVM".

Of course, maybe it's me. But I have no trouble using F#, Racket, Elixir, Erlang, or several other languages. Yet, I have struggled every time to get going with Clojure.
You can see in the video that it’s true. In their experiment, the lower hood, at same speed, makes the pedestrian hit the car 3 or 4 times instead of twice with the taller vehicle.

Mind you the taller car was only about elbow height, not like some lifted trucks you see these days where the bumper roughly aligns with a person’s hips.

So when 'the west' ignore things from other nations we're sidelining them and destroying their heritage. But if we take an interest in their culture and take it on board, it's cultural appropriation? What are we supposed to do. Say how great X is without ever doing X?

I’ve been busy the past few days, and haven’t been on HN. If you’d like to chat sometime, I just created a Twitter throwaway account: @ancapistani_ (note the trailing underscore)

Shoot me a follow and a mention, and we can chat over DMs if you’d like, or move to another platform. It’d be a lot easier than a long-running comment thread here.

A couple quick thoughts:

> Of course you have built in an escape-hatch for yourself with the 'if I am wrong' bit, so kudos for that. I guess you can use that to have a clear conscience since you appear to have intelligence and empathy enough to know what the consequences are if such a philopsophy fails.

Well, I’ve been wrong on things before. It seems to happen less as I get older and gain experience, but one that same experience leads me to consider the consequences of my being wrong and mitigate them to the extent possible when recommending a course of action.

It only takes one time of recommending a company move everything over to microservices to learn that lesson!

> For what it is worth, the preceding was written in a non-combative stance, so please don't interpret it that way (it is judgmental, though; I can't help that).

So no, I’m not going to interpret defending your beliefs as being combative.
