I believe this is false in the sense that Mercury's orbit is more centered about the center of the Sun rather than the barycenter of the solar system (center of mass).
True, but on the other hand you'd probably need a lot less boots on the ground if you can amplify their power by technology, I suppose. You can pay them more than well to guarantee their support, feed the dogs well so nobody gets any ideas about questioning pig supremacy.
Totally agree. See also: https://en.wikipedia.org/wiki/Fourth_Estate
So true, the opportunity to leave things better than as you found them is one of the primary rewards in fixing bugs in existing/old/legacy systems.

My suspicion is you're being downvoted because your comment comes across as bitter and irrelevant.
“Legal in California only for off-highway use” is a dodge of the law (at least in the intent of the law, though perhaps not in the fact) for at least 95% of products so labeled.
This is missing the point entirely.

The reason she couldn't sell T-Shirts is because she didn't build a real audience around her. She likely used bots to boost her followers and raise the status of her profile without actually building engagement.

People who have built real audiences around themselves using social media are superstars. Casey Neistat and MKBHD can sell tens of thousands of T-Shirts if they wanted to.

The only point this makes is that Social Media is a tool. It can be used well or it can be used poorly.
Are you on a Mac(book) ? I've tried fixing it, seems to be a rendering issue with upscaled text looking bold. It can be fixed with CSS but the editor use a canvas element. Ive not put much effort fixing the issue thought because I think it looks OK.
I don't actually know the answer, but my guess would be it's because of scoping. Web workers aren't a language level feature, so they can't really dictate that the function body can't have access to the outer scope which functions in JS typically do. And if worker functions like that would have access, how do you ensure thread safety? Making it so you have to point to a different module altogether seems like a decent way to enforce that boundary.

People make good points about how digital media is ephemeral (many then go on to assure us that this will lead to the Fall of Civilization).

Then there's delightful efforts like this.

This example gives me faith that the important things will be copied and recopied as necessary, and the ephemeral things that are lost might not be all that lost.
The New Sobriety
What do you do with your PrtScr key?
I recently switched from a MacBook to a Thinkpad X1 Carbon running Ubuntu Linux, and the PrtScr key is annoying! I've settled on mapping it to the Win key, for symmetry with the left side of the keyboard. This seems wasted b/c my most common use of the Win key is Win+Arrow to resize and position windows, but the most natural way to do that is the left hand pressing the Win key and the right hand pressing the arrows.

What do people do?
you also run the CA.

anyway nothing new here. these techniques have been deployed for ages. the simpler certificates supported natively by openssh are much better since they avoid x.509 complexity, unnecessary for such short lifetimes and extremely limited application profile.

you do hint at a good point though, the security posture of the CA and method of authenticating to the CA isn’t discussed. user/pass to the CA in many naive environments will reduce the ssh auth to that level.

overall, a worthless article.

Our Universe May Have Emerged from a Black Hole in a Higher Dimensional Universe
I'm not aware of a passive spaced repetition, which just presents items in increasing intervals without interrogating the subject's recall.

For all intents and purposes, the normal SR that everyone uses in the form of software and that everyone refers to when they use the term SR is not orthogonal to quizzing; it's quiz-driven.

I don't think that a passive strategy could be anywhere near effective as the actual SR algorithms in use, which incorporate feedback from quizzing in order to adjust the interval for each item, so that difficult items remain on short intervals while easy items recede farther into the future.
Ask HN: Do I belong here if I'm not CS degree?
Turning one piece of software into another is something which offers a spectrum of techniques which range from micro-refactors up to full rewrites. If you find yourself reaching for the full rewrite option, you should realize you have suddenly reached to the very far, far end of the spectrum of options and are basically taking an extreme viewpoint. If you haven't gamed out and really tried to rule out options across the entire spectrum, you've failed -- not just because you've been negligent in terms of planning and trying to make the best choice for your organization/team, but also because if you do end up doing the rewrite, you've made a specific choice that, unlike most others, infuses a large amount of existential risk to the organization and product.

In the case of a full re-write, there really must be no other way to accomplish the goal. How many rewrites happen when there was literally no other way? Engineers seem to have a bottomless well of creativity when it comes to solving problems, but that creativity often evaporates when focused on the problem specifically of "How the hell do we get from A to B without a rewrite?" No pain, no gain.
Of course, I was just illustrating with an elementary electromagnetism example that the risk isn't zero.
The real question that should be asked is there something fundamentally better than the browser and html. Things like flutter make me think there is a future for native apps that are just as easy to create if not easier.
more or less, yes. of course the devil’s in the details.
It is a big project in terms of people, and it's not impossible that bill of materials was referenced at some point. Even if not, the netlist which must surely have been provided for testing purposes must provide many clues (unrealistic example: AVR8_RX). Even if "only" PCB manufacture was done, there's a lot of information, on par (better, in fact!) with xraying the assembled product.

If you try to build the most flexible, scalable solution on day one, you are very likely to make the wrong predictions about the architecture you will need in the future. You will probably need to rewrite the software anyway.
What your phone apps say about you
I don't even know who these people are, really; their posts are a commodity to me.

The T-Shirts are created on demand. The stock is virtual, and effectively endless, with the selection as expansive as the digital designs uploaded. However, the posts are even more of a commodity. All media is becoming an ephemeral commodity. This can even extends to apps and games. Given the recent history of media, it seems inevitable.
And everyone knows there are conscious agents who can't hold a sensible conversation: toddlers. They're more conscious than any chatbot could ever be, but they'd fail the Turing test. So would dogs, and dogs show more recognizably cognitive ability than a chatbot. Let alone nonhuman primates, who are all much, much smarter than a chatbot and would all fail the Turing test.

It would be one thing if we had built an apelike intelligence and found it impossible to make something smarter, but as we can't model them either, worrying about not entirely understanding language seems beside the point.
Mortgage rates might be dropping, but where I live, a 50's era bungalow goes for an easy million. It's hard to justify buying such a heap for that kind of money when you know you'll have to spend just as much on top of that just to maintain it for the long run.

Its much easier to rent a nice place than buy one here, unless you're willing to buy a condo surrounded by AirBnB units.

Understood, not planning to do this immediately.

I've also considered trading the VIX, but the only ETFs I've found seem somewhat uncorrelated or less volatile. Can VIX be traded directly?
The problem is it’s not linear. You can ship until you can’t (or can but very very slowly). It’s taking all of the hit now or a little at a time until things completely grind to a haunt.

I’ve been involved in a few rewrites as well. Some went well and we had a noticeable productivity gain. Some went badly and we were stuck for a long time fixing bugs and corner cases we had already addressed in the legacy stack. It really depends on the situation.

> Faith doesn't select a model.

Yes, it does.

> A model is based on evidence of the senses.

No, a model is an abstraction by which one conceptualizes phenomena, regardless of the basis. It seems true that a model not based on structured application of sensory observation is likely to be a poor model if you judge quality by how well it lines up with future sensory observations, but a model is not necessarily a good model.

Faith, also, does not dispense with evidence of the senses, it just applied it differently.

“I perceived X describing Y as true”, where X is a (natural or supernatural) authority figure is sensory data, as are positive sensations associated with a particular belief. Now, they aren't sense data that empiricism would treat as relative to the truth of the belief at issue, but that's a different issue.

I'm pretty sure I know the exact product being described. It is Anti-Malware by Malwarebytes.

Being a customer for many years, I saw the downward trend and it corresponds to that described in the article, both chronologically and by meaning.

P.S. I can add up a lot to this story from a customer's point of view. Let me know if you are interested, I will continue in a comment below.
Part 2 of the article is really good. It’s a shame if people are put off by the premise of the article. The authors have already pre-judged the outcome though.

“Because machines lack an inner mental life...”

Right, well that’s it then. Case closed. No point in researching general AI any more, might as well put all those researchers on unemployment benefits.

The authors do say we don’t know how to engineer a machine with an inner mental life and consciousness, and this is true. It’s why like you (dmreedy) I’m a skeptic of claims that general AI is just round the corner. It isn’t and the Singularity is a good long way off. Our current efforts in AI are pitifully primitive, at best many orders of magnitude dumber than a fruit fly. That doesn’t lead me to believe therefore that we will never learn to solve this problem, or that this problem is in principle not solvable.

Creating microbes for eating plastics seems like a recipe for a lot of goo....turning all our insulation, computer gear, and a billion other things in our homes into microbe food seems to me poorly thought out.
I've been through successful rewrites. I think rewrites make sense when your product has scaled very fast with 50x more engineers or 50x more demands on it, so the context in what was made doesn't make sense anymore. You need a faster language, a stricter architecture and code discipline to deal with +100 engineers working on one product vs the previous 3, etc.

Rewrites in that case is more like your old wooden 4 story office is too small, so now you need to build a skyscraper out of steel and concrete. While the steel concrete structure is being built, you still keep an maintain your old office since it's running your business, and you have the budget to simultaneously maintain both. Steel structures require different building techniques than your wooden one.

That kind of hyper scaling is really rare outside of SF venture capital companies, so in most cases, you shouldn't do rewrites.

In finance there is the concept of "Risk Adjusted Returns" -- in the case of a re-write, time efficiency is not a sufficient conceptual framework for talking about it, because it's risk laden. For example, I would much rather take 2x as long to accomplish the goal, if its 10x less likely to result in catastrophic failure. A failure to recognize the risk vs time tradeoff I think can lead to a failure of being motivated enough to "work the problem" -- often there is a continuum of changes that exists -- and it might not be "smooth" and could be in fact quite painful -- but it will be way, way less risky. It's often so less risky to transition software incrementally vs bet the farm on a rewrite, I feel like in most contexts a rewrite should just be ruled out completely without further discussion: better to just muddle through and try to figure out a way to survive without it, since you may come up with a better solution that is less risk laden just by waiting (due to new ideas, new technology, new market opportunities, etc) and not stalling your current product development and risking that you'd effectively destroy everything of value you've created so far due to total stagnation.

No, repetitive work is what machines are best at. Meticulous implies attention to detail and nuance, exactly where machines fall down.
Unfortunately, restricting to only computable maths means disallowing the natural numbers, basic arithmetic, or any equivalent structure, since Gödel incompleteness would apply. I doubt any system without access to the full set of natural numbers or basic arithmetic could qualify as "general AI".
fancy titles are useful when you are dealing with Big Enterprise Clients. "CTO of TinyStartup" means you get taken slightly more seriously than "some rando building stuff".

In fact, it's not even with the people you're directly dealing with where this becomes useful (as, if you're selling to Big Enterprise Client, you likely have a network inside the company anyhow). It's when the person you have a relationship with has to convince his/her boss to approve an invoice from your little shop.

Depends on where the chip is and what it did. It's possible to hide chips between layers, hide chips under chips, replace an existing chip with something that looks almost just like it with additional functions.

It's really not hard to imagine some smart people being told to make it work.
Indeed. Imagine termites, but at a far bigger scale...

Don't forget all the very important medical applications of plastics where their inertness matters --- if organisms exist that can start eating away at those, and proliferate, it could cause even more damage to human life.
Nuclear waste is also mostly fuel for hybrid fusion-fission reactors. From Wikipedia[1]:

> Hybrid nuclear fusion–fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The basic idea is to use high-energy fast neutrons from a fusion reactor to trigger fission in otherwise nonfissile fuels like U-238 or Th-232. Each neutron can trigger several fission events, multiplying the energy released by each fusion reaction hundreds of times. This would not only make fusion designs more economical in power terms, but also be able to burn fuels that were not suitable for use in conventional fission plants, even their nuclear waste.

As an extra advantage, such a reactor would be subcritical (similar to a Accelerator-driven subcritical reactor [2]) so it would never be at risk of a melt-down.

On the other hand, I'm pretty sure that such a reactor would still be a proliferation risk like fission breeder reactors.

The color of the brown is also not the same: in addition to the several pixel transition area which depends on the stripe color there are slightly red, green, and blue tinted patches in the rest of the brown that differ based on the stripe color, which helps create the neon glow effect. Calling the balls all the same color seems to be entirely incorrect.

I also see an "egg" illusion where it looks like the lower left of the ball is actually flat but the rest is a dome.
I used to dress relatively well.Lots of good quality clothes. Then I put on lots of weight and was like " fuck it,I look like shit anyway", so started buying the cheap stuff. A pair of jeans-£6, t-shirts-£3, etc.The only exception is footwear- I don't buy cheap shoes,as they are crap. £6 jeans last only a couple of months before they become unwearable,as the material is usually subpar. So I kept buying them every 2 month or so. However recently I stopped buying this cheap crap,and usually buy clothes that are high quality and they do last. That's how I'd describe less consumption.
I don't think anyone who knows what they're talking about is worrying about supply chain risk, what they're worried about is backdoor risk. Controlling pcb manufacturing is a good way to be able to put all sorts of surveillance chips, backdoor chips, etc. on the pcbs.

I think the concern is that a nation that has literal concentration camps and exhibits any-western thought and agendas is going to become a major power.

China is hardly going to "eclipse" the US. I think the concern is less economic and more geopolitical. It should worry the West that a highly authoritarian nation is becoming wealthy and powerful.

It's a reasonable concern, I think. Once China gets hard geopolitical power it will start to export its own way of thinking, just as the US did. But unlike the US, which at least in theory believes in basic rights, China is a literal authoritarian surveillance state with no such values.

I worry that state run concentration camps like those in xinjiang will become normalized.
