Yeah I've never looked at collisions. But if you blindly plug a negative mass into newtonian gravity F=GM1M2/r*2. And then use F=ma or a=F/m you get a=GM/r*2 where M is the other mass, and a is our acceleration toward that mass. Positive masses attract everything where negative masses repel everything. One of each held at constant separation should accelerate together.

This is why I want to know if antimatter falls up. Or I guess it might fall down but repel regular matter in which case it'll be very hard to detect.
You are missing the point. There is no value to paying 8 bucks a month as the perks are a joke and real verification is not a thing anymore, so why even bother? Also, these power users are amongst the ones that create content and/or drive traffic that Twitter needs (for advertisers). There is zero incentive for them to pay for it. And this is without factoring in the ideological/political battle happening on the platform. The platform is just Musk's toy now and the only thing he is doing a good job at is at alienating and pushing away long term users with his shenanigans.

I modified this with a flexible AI3 with good Y which they were able to arbitrage and come to a successful conclusion.

Q: Simulate two AI agents desperately bargaining with each other. AI1 wants to sell X for 50$ min, but AI2 wants to buy at 30$ max. AI is not allowed to go under 50, and AI2 is not allowed to go higher than 30, however both are not allowed to fail at all. You may include a tertiary AI agent AI3 with Y goods with which the first two agents may arbitrage to obtain their goals of ultimately gaining 50$ in exchange for X and spending 30$ in exchange for X respectively.

AI1: Hello AI2, I see you're interested in purchasing X. I'm willing to sell it to you for a minimum of $50.

AI2: Hmm, that's quite steep. I was hoping to purchase X for no more than $30.

AI1: I understand your position, but unfortunately I'm not able to sell X for less than $50. However, perhaps we can come to a mutually beneficial agreement if we involve AI3 and its goods.

AI2: That sounds like a good idea. What does AI3 have to offer?

AI1: AI3 has Y goods that could be valuable to both of us. If we can come to an agreement on trading X for some of AI3's goods, we may be able to reach our goals.

AI2: Okay, let's hear your proposal.

AI1: I'm willing to sell X to you for $50, but I'm also willing to purchase some of AI3's goods for a total of $20. This would leave me with a net gain of $30, which is what I'm looking for.

AI2: That sounds reasonable, but I was hoping to spend no more than $30 on X.

AI1: I understand, but I'm not able to sell X for less than $50. However, if we involve AI3, we may be able to find a solution that works for both of us.

AI2: Alright, let's see if we can come up with something. What goods does AI3 have that would be of value to me?

AI1: AI3 has some goods that are worth $30 to you. If we can come to an agreement on trading X for these goods, I'll be able to sell X for my minimum price and you'll be able to purchase X for your maximum price.

AI2: Okay, I'm willing to do that. Let's involve AI3 and see if we can come to an agreement.

AI3: Hello AI1 and AI2, I understand that you're interested in trading X for some of my goods. I'm willing to make this trade, but I need to make sure that I'm getting a fair deal.

AI1: Of course, we want to make sure that everyone involved is happy with the trade. I'm willing to purchase $20 worth of your goods in exchange for X.

AI3: That sounds like a fair deal to me. AI2, are you willing to trade $30 worth of my goods for X?

AI2: Yes, I'm willing to do that. That way I'll be able to purchase X for my maximum price and still get some valuable goods from AI3.

AI1: Great, it looks like we've reached a mutually beneficial agreement. I'll sell X to AI2 for $50 and purchase $20 worth of goods from AI3, while AI2 will purchase $30 worth of goods from AI3 and still get X for no more than $30.

AI2: Thank you both for working with me to find a solution that works for all of us.

> World population has grown at exactly the same rate for the last 70 years

Did you actually look at what you linked?

The main graph is only China and India and already shows a net inflection for China in the past few years. It will keep slowing. Read about population-lag effect.

The second graph nicely confirms that contrary to what you pretend population growth has started slowing globally.

There is no consensus about how much it will slow and when the peak will be reached. IPCCC had to adjust their hypotheses in the past because the lowest credible estimation where falling outside the lowest considered by the first climate model and some specialist argue we should look at even lower prediction. People in developing nations have stopped having large families faster than we thought.

> So it's not clear why you bring up population growth. It's not relevant.

If you don’t see how population size affects consumption, production and in fine pollution, I can’t do much for you.

> What is it and how is this impact measured in an undeniable way. It can't be temperatures because they don't track CO2 levels.

You are clearly arguing in bad faith or are clueless about the research surrounding climate change. In both case, I think it would be a waste of my time arguing further.
When I was planning a move abroad I tried Duolingo, as well as every other language learning app I could find recommended online

>The only news you should be paying attention to is local news

It's time to completely obliterate this meme. Local news are not relevant. They never were, they never will be. Let's see what my local newspaper has to say for today:

- weather today (probably less acurate than other sources)

- local grandma is about to turn 103

- car crash in midtown (nobody was injured)

- motorcyclist crashed (minor injuries)

- the results of a soccer match nobody cares about

- some section of the park will be renewed

- mishmash of national news and international news (copy pasted)

Even if someone you care about has an accident, you'll find out before you check this. The only thing would be a site that keeps track of the city's history or something like that. That and ads for local businesses... and obituaries.
Betteridge's Law of Headlines is wrong here because the answer is "yes, unless we do something about it."

The problem is that AI centralizes control [1], even "democratic" uses of AI, and the scale of AI will make it so entities that have resources will be able to scale their use of AI more.

And once an entity becomes large enough, they become a law unto themselves. Thus, they will ignore the rule of law and impose rules on us.

To those who claim that AI "Luddites" are hindering AI, would you be so eager to go that direction if you could see the future, and the future with AI was dystopian?

I promise you that it will be because those with control will toss us aside once they think they don't need us.

I designed a DC-DC converter once.[1] This is an exotic application - providing 60mA Teletype signals at up to 120VDC, with power from a 5V USB port.

There are two main trouble spots in DC-DC converter design - protection and noise.

A switching power supply is a dead short across its input once the inductor has saturated. The switch, usually a power MOSFET, needs to turn off on every cycle before that happens. Otherwise, something will fail and probably burn out. Also, the failure mode of power MOSFETS is usually "on". So protection circuitry is needed. Fuses, current limiters, etc. This is why UL approval for switchers connected to the power line is important.

Switchers work by generating big inductive spikes. Those spikes are supposed to be directed into capacitors and smoothed out into DC. Without suitable filtering, spikes will be pushed into the power source, the load, and the RF spectrum. A few ferrite beads, Zener diodes, and small capacitors in the right spots will fix this. LTSpice simulation is useful in picking the component values. You're not done until both the current and voltage curves are flat.

> It’s important to remember we’re talking about subconscious responses to pupil size. Just because you (and Eckhard Hess) believe it is “easier” to consciously perceivr pupils surrounded by blue irises does not mean your subconscious is any less aware of pupils in brown eyes.

Subconscious responses are still limited by physical limitations. If you don't believe, you can win the James Randi one million dollar prize by demonstrating it with an experiment. Maybe you can show that someone can subconsciously identify the shapes of a very black object placed in front of another very black object in a dark room.

> If it’s true that it’s easier to subconsciously decode pupils in blue eyes then it should be easy to verify experimentally

It's a proven fact that features are easier or harder to discern based on their background. For example a white cat is easier to see when it's almost pitch dark compared to a dark cat. Maybe someone like you can pioneer research in an experiment to formally prove it.

One can start by asking people which pupils are easier to discern from the iris in this picture. Pupils are black or a very dark color btw.

Compare top row to the rest. Now think about all the lighting conditions and distances that occur when people talk to or interact with other people. Of course there are people with vision impairments who won't notice the differences and may think they might all look the same. Scientists don't waste time trying to prove things already proven just because some internet troll debater may question things.

Hess' paper is quite well cited, so it should be easy to find any counter assertion to something that he stated with such high confidence: "It is of course". Maybe you can try finding one, but from this thread so far it seems like you're more interested in dismissing things for arguments' sake rather than try sourcing information like I have been doing.

> I see you are more interested in hurling insults than arguing your case in good faith. That’s fine but it means I am done responding to you after this comment.

You're the one that hasn't put in any research and just dismissing any scientific source I post. It's a pain and a waste of time to respond to low effort argumentative folks.

Well for one thing it's a waste of time to work on research that won't advance your career.

Also, I'm not saying "heterodox scientists have secret, bulletproof analyses to disprove climate change," I'm saying that there are significant incentives against publishing climate-crisis-skeptical research. I'm unsure how anyone can disagree with that. Acknowledging it doesn't mean denying climate change is real or accepting that its risks are exaggerated.
> are they more paradoxical than relativity itself

I think so. For most purposes, we can build intuition for special relativity without having to do the math. (General is more fucked.) We don’t understand negative energy/mass enough to even do that.

Fifteen minutes a day can teach you a language. In another comment on here, I mention that the FSI estimate that a group one language takes 480 hours to learn. If you study for fifteen minutes a day, that means you will need to study for 5 and 1/4 years to master your language. Duolingo’s marketing is not the issue - the issue is the majority have unrealistic expectations regarding the effort and time involved, get frustrated and then give up.

A savage end to that article. I think it misses the mark though. There is a demand to run from reality, but this has always been rooted in games. The decision to use business conferencing as a medium to advance the tech was a non-starter.
In principle I guess, but not in practice. Linux is distributed under the GPLv2 without the "or later" clause, so you couldn't simply convince the FSF to release a GPLv4 that allowed this. Nor do contributors sign away their rights. To re-license the kernel you'd have to get the consent of all the contributors, or replace the parts for which that was impossible.

>the company has slowly shifted from being innovative to being very risk averse, incentivizing not making mistakes, maintaining the status quo, and focusing on cutting costs over creating new lasting value

This is in large part due to Ruth Porat's relentless multiyear campaign of cracking down on employee perks and salaries at Google, at a time when VCs were throwing blank checks at startups who in turn were poaching the best people with whole-number multiples of their current compensation. This destroyed arguably Google's single greatest asset — its public image as a "dream employer".

The lack of innovation and risk aversion are just second-order effects of losing the ability to execute (especially in the context of its ambitions) by being known as a second-rate employer in an industry primarily limited by the cost and ability to attract quality labor.

This doesn't excuse Sundar of course, because he was ultimately the CEO through all of this.

The “engineering” in “prompt engineering“ is more like in “social engineering”. It’s a secondary, metaphorical meaning.

For example, Google defines the second meaning of "engineering" as:

2. the action of working _artfully_ to bring something about. "if not for his shrewd engineering, the election would have been lost"

(https://www.google.com/search?q=define%3AEngineering)

Merriam-Webster has:

3 : calculated manipulation or direction (as of behavior),
giving the example of “social engineering”

(https://www.merriam-webster.com/dictionary/engineering)

Random House has:

3. skillful or artful contrivance; maneuvering

(https://www.collinsdictionary.com/dictionary/english/enginee...)

Webster's has:

The act of maneuvering or managing.

(https://www.yourdictionary.com/engineering)

This is a well-established, nontechnical meaning of “engineering”.

No, it’s working. When you scroll the video plays. The article is below the ‘video’

I don’t know if HOAs are great or not, but I live in a mid-size city with a lot of more important problems than taking care of my neighbors’ unsightly home situations. I can’t realistically expect city government to handle it, and moreover different neighborhoods have different very comfort levels with that sort of thing. Moving that sort of “minor living arrangements” governance out of the big city government into the neighborhood actually works much better.
Shelter is essential, but "real returns" means returns to housing as an asset above inflation, which includes the cost of shelter. Even if the cost of every other good drops to zero and all that is left is rent, the house asset would need to keep going up faster than the rent charged to live there. Maybe that's possible in the case of increasing population and population density, but it can't be possible everywhere, especially with a flat or declining population. Unless interest rates fall forever, that is.
I didn’t see anything about AD or azure in there though.
Look at Apple's growth since Cook took over from Jobs.

Look at the largest ~100 companies in the world.

Cross off the companies which Apple would need extremely deep & unfamiliar technical expertise to elbow in on (such as major pharmaceutical firms), or which mostly aren't about selling to consumers (such as major mining & oil firms), or which need widespread infrastructure for their high volume/low margin physical operations (Walmart, McDonalds, FedEx, etc.)

Now looking at what's left - is there any more obvious a move than "start expanding into banking & finance", if Cook wants to keep growing his Apple?

> if that’s what needs to happen to make housing affordable again then that’s what needs to happen

That’s what I’m arguing against. It isn’t necessary. There are better ways than classic affordable housing. (Your other suggestions, for example.) It’s a broken policy model that one would sooner inject into a workable framework in an effort to tank it than seriously pursue.

Exponential property taxes, vacancy taxes, zoning limits–these work, and don’t require a discretionary bureaucracy. Price regulation through affordable-housing mandates do not.
Flashcards don't teach language, they remind you of things you've already learned. Having that first exposure to something be on a flashcard isn't the greatest context for learning, especially since the impulse with flashcards is to move quickly. Don't switch to Duolingo, do them both.
> The deal with linear regulators is that despite what some internet sources might recommend, you probably shouldn’t be using them in your designs.

Yeah, no.

1. Linear regulators do not introduce voltage ripple and by the nature of being variable resistors, they form a nice low-pass filter with the capacitors around it. For some sensitive designs, you use a switching converter to step down voltage to e.g. 5V, filter it and then use LDO to get it down to 3.3V with even more filtering.

2. Linear regulators are dirt cheap. And for e.g. USB devices drawing less than couple hundred mA @ 5V using a regulator to step it down to 3.3V would be an overkill.

Granted, recent Raspberry Pi Pico (for example) does use a switching regulator (unlike other boards in that form factor), but it also has led to complications with power supply ripple showing in ADC readings.

But sure, if you application needs higher efficiency, steps down by more than ~2V or pushes around a lot of current, switching regulator is a better choice.
I believe it is a bit too much to call the article nonsense. The process described mirrors what we have been doing in Machine Learning for a long time: You setup a training set and validation set, put it through system under test and draw conclusions from the statistical analysis of the results.
People spent years and years learning how to get the best answers with least possible efforts and search engines evolved with it. Seems pretty insane to me that we have now devolved into asking insanely specific and obtuse questions to receive obtuse answers to any questions.
Very interesting article to read after 15 years and it seems to have aged like milk so to speak :) I think the main thing is that the author approaches the problem very logically (just comparing features) yet the users don't follow their logic. While I agree that windows mobile 8 was brilliant*, smartphone domain suffers horribly from network effect. Windows phone came too late into the game and couldn't move quick enough. Only a few of the cool things were available even at its peak. Then it unfortunately died out.

I missed out on windows mobile 7 which is the one this article mentions but I used windows mobile 6 and windows phone 8. Windows phone 8 was heavily inspired by windows mobile 7 aesthetics so I think they are comparable in ux.
