The reason you prefer cars to be lighter if they're going to get into collision is because cars can absorb only so much kinetic energy before it spills out and affects the squishy humans inside. You're optimizing for safety of the passengers of both cars simultaneously.

Satellites don't have this constraint. Of course you'd generally prefer smaller sats to collide (smaller = less fragments), but assuming fixed size, denser (= heavier) pieces will have more inertia, and so deviate less from their original flight path. This keeps the debris trail more concentrated. If only one of the two is heavy, the pieces of the heavier one should end up more concentrated. I'm not sure whether the wreckage of the lighter one gets spread more widely, or - with these velocities - just flash-fuses itself with the heavier one.
I'm sorry Rubatuga, I flagged you. To be fair: I'm not having the best of days, so I might be a bit quicker to flag, but I find this behavior on HN unacceptable.

You make an overgeneralized claim ("this is all") and give no evidence.

There is an extreme amount of evidence on the contrary that the WHM has a lot of novel scientific elements to it. See [1] as an example.

Here is an argument for why we are not/ we shouldn't try to run simulation. I haven't seen this argument so maybe its flawed.

If we have non-zero chance to live in simulation, then running our own simulation will eventually have a chance for cascading simulation effect (each simulation runs one or more subsimulations). This puts ever growing strain on amount of power needed to run the whole system at the top level.

At the top layer it might mean that simulation might be slowed down - time resolution slow downed (un-perceivable to us in simulation) to level where simulation becomes unusable/no value running it.

At this point the simulation might be killed/rebooted.

So if we have non-zero chance to live in simulation, creating our simulation might mean we are dooming ourselves.
> To create a new page, the mining network is assigned a sort of puzzle, called a hash function, by the Bitcoin program. Solving this type of puzzle takes many resources- expensive ASICs and a lot of electricity to run them around the clock. The name of this puzzle is known as the hash function SHA-256.

The article skips the notion of Proof of Work, which is the formal term for the puzzles. And puzzles can take many forms besides finding small outputs of a hash function [1]. The latter is just Hashcash, of which Bitcoin's PoW is an instance.

I’d say rather that they’re coupled to the behaviour of the object.
I stand corrected. There was a time when I watched several shows like Morse (ie, Lewis, Frost, Foyle, Gently, Lynley, Marple, Midsomer) and I suppose it became a bit of a blur. It was a lot of long episodes, but not a lot of episodes (per season).
There's the paper: “Brain over body”–A study on the willful regulation of autonomic function during cold exposure (DOI:10.1016/j.neuroimage.2018.01.067)

From the abstract:

"Our results provide compelling evidence for the primacy of the
brain (CNS) rather than the body (peripheral mechanisms) in mediating the Iceman’s
responses to cold exposure. They also suggest the compelling possibility that the WHM
might allow practitioners to develop higher level of control over key components of the
autonomous system, with implications for lifestyle interventions that might ameliorate
multiple clinical syndromes."

I was doing cold exposure for a while, plunging palms and heels into water with ice. At first I could hold it a little there, but the duration was increasing with time. It's comfy to do while using laptop, mind doesn't focus on the hell going below :)

This goes back to my thought on compressibility. The article's argument is built on the assumption that some data in the universe can be ignored and the whole computation made more efficient.

It's not a trivial assumption. I actually lean towards an incompressible universe, intuitively.

If the universe is incompressible, then you may only ignore parts of the data for a finite time. For example, arranging an illusion of the night sky might have taken no computation before astronomy, but as we record the positions of celestial bodies and understand the laws governing them, the computations have to be run retroactively since the big bang. Otherwise the simulation would be inconsistent.

So the question is what can you remove from the causal chain from the big bang to this moment? If you think some things are removable, you have to prove that something exists in the universe but does not touch any causal chain humans (or perceivers) may wish to investigate at any point in the future. If nothing is removable, then you cannot choose to not simulate any part of reality based on perception, because whatever you don't simulate may eventually need to be simulated.

Given SpaceX's (and Amazon's) plans to deploy upwards of 12000 LEO satellites, how do they factor for avoiding these debris (given Kessler Syndrome's premise that this avoidance is only going to get exponentially harder as time goes on and not easier, especially what seems to my untrained eye one satellite too many)?

Also, how do Rockets and other launch vehicles avoid these (I am guessing the debris are extensively tracked or are the launch vehicles built to withstand hits)? Excuse my naivety but it seems like a future where humanity locks itself out from Space altogether isn't a distant possibility at all but one that could happen in our lifetimes?
It's a lot easier for some mobile companies to roll out 5G than 4G too. Vodafone in the UK were still rolling with point-to-point microwave connections between masts all over the place before 4G and had to ditch that to get the bandwidth needed to support it.

It's possible that a bigger universe exists that can simulate ours.

However I think whether a simulation of only the perceivable universe is not possible, which means you can't reduce the required computation. See my reply to a sibling comment.

If the universe is incompressible then it's definitely impossible to simulate it within itself.

I really don't think this started in the 1990s. The tension between commercial needs and artistic purity has existed for as long as there has been art[citation needed].

Some more modern art forms like TV and Film are very expensive and so particularly sensitive to commercial interests but it has always been true - artists have to eat just like everyone else.
Why do fakes need tests, but mocks don't?

In one case you create the class on your own, in the other case the mocking framework does that for you on the fly. With both approaches you can do very basic or very complicated things.

Or do you have a rule in your company that every class needs a test? Maybe this rule is the problem.

I believe that Yahoo's data breaches [0] was one of the main reasons that killed them. People were abandoning the ship in the millions after that fiasco. Until then, they had it good. Thet could get all the ad sales they could handle, they were reading the emails of millions (exactly like Google, Microsoft, and other 'free' services do), they kept tabs on everyone.

They dropped the ball so hard, it just did not bounce back after that. "Lately", every time I duck (DDG) something and I see it's a yahoo hosted site, I just close it and go to the next. I am in Europe, GDPR is, thankfully, the rule here, and the number of <bad word> trackers, advertisers, and other crap that I have to agree with to read something in the Yahoo universe is "too damn high" (to quote the meme).

That's true.

I'm only arguing against partial simulation within our own universe (eg. The Matrix). Any simulation that has a night sky and telescopes must simulate the full big bang and evolution of galaxies just for the people on Earth.
I also like dynamic CMS more than static websites, there is something really cool about being able to access your editor and directly update your content. Of course things don't have to be black or white, I'm using Grav, it's a lightweight CMS that uses static files for its content and generate a static cache when something change, so you technically only serve static content but still have the benefits of having an admin UI to manage your website and content.

Situations like these are why I like the networking system of Qubes OS. With it you can plug any network VM in front of your applications, usually TOR but there's no reason why it can't be a corporate VPN, and let the rest of your software use that as their uplink.

Vendor VPN software will probably never be fixed; there is no financial incentive for playing nice with other vendors and incompatibilities in upgrades means their locked-in customers who need to work with other companies are only incentivized to also upgrade. Sadly a system like Qubes' or using VMs will probably be the only way to combine VPNs from different companies and/or vendors for while...

First I'm seeing of unison, will have a look thanks. My primary language became Go when that came out, and I don't foresee myself moving to another language until there's a paradigm shift. Meaning, I think the majority of services we need will be written in Go and be exposed as very standard consumable APIs much like unix tools were with text. The shift beyond that, I think is to a language that understands a live environment of these services as opposed to yet another language that looks to replace existing languages.

Basically I think Go is the last language needed on the backend for the way we write software today much as C reached its pinnacle 10-15 years ago. C program moved to Java or dynamic scripting languages for different platforms. Go dominates the Cloud and I think the platforms we program for beyond that might be something higher level. Maybe voice. Maybe something visual, who knows.

One of the most important design principles is consistency. Unfortunately that's an objective which is difficult for open source to fulfill. It would be great if the desktop environments themselves took the task of providing a couple of unified themes out of the box, where the colors, icons, fonts and everything else fit together.
Without interoperability and universal identity, social graph doesn’t help.

Universal identity, you can maybe solve with email. But there are problems like requiring using real name, multiple accounts etc

I'm a bit sceptical - not rubbishing, but sceptical - of the castle walls analogy.

If an attacker gets through your walls (network access), why do you think you'd stop them at the keep?

I think castles have something of an answer to that question, because physical static defence is just more constrained than computational static defence - the ratio of effort of building a wall : effort to breach is poor compared to even complex passwords.

Your REAL physical defence is(are?) your soldiers, and the wall mainly aids their co-ordination: small attacks aren't worth attention, big attacks are SLOW AND VISIBLE. Does infosec have a similar wall to that? Certainly, when attackers breached castle walls via backdoors, it was normally game over, keep or no.

This is an interesting complaint in contrast to films. The normal complaint with films is that there is never any new IP, it's just sequel after sequel.

In most async implementations the final stock check just cancels the order. Which is fairly rare.

An eventually consistent implementation is good enough for displaying to the user.

The extra complexity of displaying consistent and up to date stock inventory to user isn't really worth the cost instead of the fairly rare occurance of having to cancel an order.

> I learned that "he" refers to a male or is neutral, but don't mind when writers use "she" as long as they are consistent about it.

This advice seems pretty questionable to me. It seems evident that neither 'he' nor 'she' are actually neutral. Even if one accepts that they can be used with that intent, they still colour ones perception of the person in the minds eye.

I'd be interested to know which pronouns you use in speech when the gender of the target is unknown. For example in the following cases:

- A baby whose gender you don't know

- A pet whose gender you don't know

- Someone who has been referred to in conversation (perhaps someone talking about "my friend") whose gender you don't know.
