Bitcoin might well be the biggest invention in open internet protocols since BitTorrent. BT was a society changing tech, i consume most of my content via this protocol today.

Before that was probably email;
In that one could send an instant post card to any address on a decentralized network of mail servers, bypassing the USPS, etc.

BTC been on HN since the launch, and the community has been mostly negative — most users didn’t see the point compared to the incumbent technologies. But I have live it, and watched the corruption and theft of savings by bank and government in multiple jurisdictions; when I saw that you could store value over time using the same technology as public key cryptography — a core privacy technology, I knew this would reshape society, in the same way that public key cryptography reshaped communication in the 90s. It was such a powerful tech that governments of the world wanted to stop it! Ban large keys under export law! Illegal numbers! Outlawed algorithms!

We see the same thing decades later at a different layer of the human stack, the economic layer.

Nothing is truly new, just a mix of that which came before.

We are now seeing lots of people building software and protocols to try to recreate this, but they miss certain key points of why the protocol works. Bitcoin is a special protocol, in that nothing has been able to recreate the mindshare, effort and energy since it’s creation.
They're actually fixing that finally (I'm sure it has absolutely nothing to do with Epic's lawsuits...)
> never about what should be funded instead.

This isn't entirely true. In this blog post (http://backreaction.blogspot.com/2019/04/does-world-need-lar...) she recommends:

> "One of the key motivations for building a larger particle collider that particle physicists like to bring up is that we still do not know what dark matter is made of. But we are not even sure that dark matter is made of particles. And if it’s a particle, we do not know what mass it has or how it interacts. If it’s a light particle, you would not look for it with a bigger collider. So really it makes more sense to collect more information about the astrophysical situation first. That means concretely better telescopes, better sky coverage, better redshift resolution, better frequency coverage, and so on."

Though she goes on to say

> "But really my intention here is not to advocate a particular alternative. I merely think that physicists should have an honest debate about the evident lack of progress in the foundations of physics and what to do about it."
That's a good description of the inherent complexity in modern compute, but there's a whole lot of accidental complexity as well. Which is why, e.g. many modern OS's and "apps" still cannot keep up with normal typing speeds without adding many seconds of latency. That's a significant impact on UX and a severe regression wrt. earlier systems. Plus lots of random slowdowns due to background processes doing whatever, etc.
> That the title wouldn’t be well known in Europe, or fully known in the US isn’t surprising to me. I’d probably expect someone who works in the start up world to know it, and would expect anyone working at the FANG compensation level to know it, but I don’t think it’s super common among the vast middle of companies.

I guess that's fair.

> (And for reference, I had know idea what SDET meant until I looked it up right now, although I certainly have worked with Software Development Engineers in Test. Probably an even more obscure term?)

I'm not sure - I work as an SDET and have found work as an SDET in Oxford and London England, remote in other European countries, and am now interviewing for several companies in the Bay Area. It seems pretty universal to me! But again, maybe that's just down to the bubble one is in. FWIW, it just means a software developer who focuses on testing as opposed to frontend or backend, so managing test infrastructure, reporting, writing frameworks for devs to use for testing, etc etc...
Nice writeup! Former chemist here. Helium is indeed poorly soluble in most liquids. It's actually used to sparge (purge by bubbling through) solvents to drive out other dissolved gasses.

This is because Helium has very weak intermolecular forces due to its electronic symmetry. For that same reason, it's also as close to an ideal gas, giving you the most pressure/volume bang for your mass buck (only hydrogen is better, and that's bad for oxidizer tanks for obvious reasons).

But this also limits the ability to cryogenically condense helium, which would improve storage density. But you really don't need much in turbopump fed engines.

In the 80s and 90s you could buy software running on Windows, where the vendor of the software didn't pay anything to Microsoft; in fact, I'm sure Microsoft was happy with them supporting and increasing the strength of their platform.

Why does this have to change now? Why does the platform need a cut?
Or you take year's congestion charge revenue and split it equally across the residents.

The goal should be shifting traffic away from inefficient uses of the infrastructure's capacity.

That should provide the economics for actual ride sharing (I don't mean single-passenger taxi rides, but car pooling and busses) which would allow dynamic networks where passengers need to switch between vehicles on low-throughout links. Think a hybrid between taxi service and bus lines.

Such a network would be able to use incremental addition of fixed line public transit without today's issue of no car-grade last-mile solution for commuter rail services.

Also, public transit gets better when more people use it, due to e.g. busses needing to run more often for capacity and thus automatically/accidentally providing nice latency.

No, not if take her at face value. She’s saying particle physics has built a framework where the goalpost can keep moving.

It’s become a bottomless trap of sorts.

Given that resources—money and bright minds—aren’t infinite, she then proposes that there are other areas of research that received less attention and are ripe for discovery.
Since we're on this subject, one question I've never seen answered is why neutron stars have such intense magnetic fields. I mean in the normal universe we inhabit, certain chemical elements are magnetic while others are not. How can neutron star matter have magnetism when there are no electrons in orbitals anymore? I mean that seems like a good question, how a relatively well understood phenomenon like pulsars seems to depend on electromagnetic behavior that can't be explained by Maxwell's field equations.
But at least you know some people have them. Plus it's extra motivation.

Maybe we can say that you should work on problems the market has, and it's especially good if they are problems you have too

It's not. Bitcoin was supposed to have a capped and fully auditable supply, to take 4 years to emit half the supply (Monero emitted 40% in the first year alone), to have a simple and instantly verifiable PoW, to have a UTXO set that's a small fraction of all TXOs (crucial for scalability), and to be scriptable, just to name a few.
Indeed. Are you suggesting, perhaps, that the promoters of the LHC were making claims that they knew could not be satisfied by it - or, perhaps, that nothing they said could reasonably be interpreted as such a claim?

What? No.

Homeless people aren't helpless animals in need of coddling. They are human beings with intelligence, perfectly capable of exploiting incentives and your kindness.

They terrorize eachother, and those who interact with them.

Dealing with fakers is one of the key problems for any service like Strava. I have a set of ten segments that I do around town, and I constantly see bike times posted as running. I think most are accidents (e.g. forgot to change the activity type on their watch) but I've noticed some folks who seem more deliberate about it. BTW it's really not hard to tell. I've even seen a couple of times that were people in their cars, but those were even more obviously accidents.

To their credit, Strava tends to be really good about taking down times once they're flagged. OTOH, one of my own runs got flagged once, and the weird thing is that it wasn't even a particularly good time or anomalous in any way. If somebody wants to erase one of my below-average runs from the record, I think I'm good with that. :D

Most Scheme implementations also implement core data structures natively rather than in Scheme. They could be implemented in Scheme, as it could in most languages, but they ren't for the sake of efficiency.

What I still continue to find interesting is that Idris2 compiles to Chez Scheme, and is somehow faster than Idris1 which compiled to C. The Chez Scheme implementation very much natively handles all important data structures.

That's why I was asking for an ELI5 explanation. I know that the equation holds and that compressibility turns everything upside down, I just haven't been able to figure out an intuitive explanation.

I have this idea that in supersonic flow, a pressure wave can't move backwards against the flow, right? Which would mean that any single molecule inside the flow has no way of knowing what's in front of it (because the information simply can't get there), but it feels the pressure of the molecules behind it, so it accelerates towards the void.

The "Fanno flow" article on Wikipedia says that "... For a flow with an upstream Mach number greater than 1.0 in a sufficiently long enough duct, deceleration occurs and the flow can become choked ... Conversely, the Mach number of a supersonic flow will decrease until the flow is choked.", which means that supersonic flow behaves differently in a diverging nozzle than in a simple straight pipe. This is the part that I don't understand. Is the friction inside the nozzle somehow inhibited by the walls of the nozzle gradually moving out of the flow's way or something?
This game is pretty fun. A lot of people say it's not intuitive, but you just need to learn basic color theory then you can start making reasonable guesses. Also I agree that "hard" mode is easier.

That's illogical. If there is congestion the problem is that the method of transportation is too inefficient. Smaller vehicles like bicycles are more efficient at slow speeds, during congestion speed is low to begin with. The right answer is to tax inefficient vehicles more and efficient vehicles less.

How can a collective group of people give consent? Basically everything any state does is without consent.

By your definition it seems social security is also without consent.

So by that logic no fundamental research should ever by financed by governments. good to know.

This makes gcc compile the code to one instruction less per iteration because it can use the status flags generated by the bitshift to determine whether to jump. Now the loop will only be 3 instructions long and the entire function 8 instructions. https://godbolt.org/z/fna8de367

> A colonel in Kansas may live like a king, but a captain in San Diego can't afford a house.

Assuming both sought living accomodations outside of free base housing, I was curious what those figures actually looked like[1]:

- O-6 colonel stationed at, e.g. Fort Riley, KS 66442, would draw up to an additional $1500 without dependents, $1911 with.

- O-6 captain stationed at, e.g. NAS North Island, CA 92135, would draw up to an additional $3342 without dependents, $4026 with.

It's worth mentioning for those unfamiliar that, just like BAS (i.e. food allowance), this BAH (i.e. housing allowance) is completely tax-exempt.

The game that active service members play here is to secure a home mortgage (often through VA home loan), then apply BAH directly towards monthly mortgage payments throughout service all the way to retirement. It's not hard to imagine other tax advantaged games to be played here. Applying BAH to rent a house off base is a naive fool's errand.

In terms of annual cost of living adjustments to base pay, uniformed service received +2.7% increase this year; in contrast, +2.2% for federal GS civilians. The year before that, it was +3% v. +1%. These adjustments have historically favored uniformed service over the federal civilians that work beside them. Sure, they're lowball relative to inflation, but that ought to be squared against military tax-exempt BAS/BAH and hugely subsidized commissary entitlements.

Exceptionally common amongst Navy personnel, married sailors typically draw an additional $250/mo family separation allowance[2] when out at sea for more than 30 continuous days. This will obviously have a greater financial impact amongst the enlisted ranks than officers. Depending on rank and job, there's a litany of allowances, bonuses and incentives (beyond the scope of this remark) that are often ignored when the conversation of military service compensation is brought up...nevermind that no one ever talks about the opportunity to retire with guaranteed pension + benefits for life as young as 38.

As an outsider, I'm inclined to agree that military health professions do seem to pay a substantial indirect opportunity cost despite the unique bonuses they're entitled to[3].

I do wonder what individual circumstances led you to choose a Navy commission over everything else?

The only outrage I feel is that Tim Sweeney is using the compensation of starving artists, the main demographic on Bandcamp as I understand it, to try and make himself and EPIC richer or more relatively powerful. I don't give two hoots about "breaking up the App Store Model" and I doubt many/most musicians do either. I personally feel that 30% isn't even outrageous considering the value proposition.

Relatively rich/privileged software developers making their problem (App Stores wanting a 30% cut) the musicians' problem isn't noble, it's evil.

Edit: The way I see it, Tim Sweeney/EPIC is responsible for breaking the status quo that allowed bandcamp’s niche to operate the way they did, which seems a reasonable assumption. That acquisition turned the userbase into a pawn in the App store battle.
