What do you mean by negatively compound? I assumed you meant that if you gain no income, losing 1% per year means you lose less than 10% over 10 years, but you don’t seem to have acknowledged that.
> If the polynomial P is invertible, i.e. has degree 1

Should be degree 0: only constant polynomials are invertible. E.g. x+1 is not invertible, and modding it out doesn't result in the zero ring.

The example is a bit confusing, because $x=x+1$ is equivalent to $0=1$, which has degree 0.
I may have missed it, but did the author try to interview whoever in Texas made the deal with the Miners? It seems that their input would be important to help us understand why they'd make such a bad deal.

Maybe it all comes down to paying off the right people, but I can't assume that until a journalist digs deep enough.
Division by zero is not defined anywhere on math.

The closest thing you'd get to it is to

1. define a limit (lim x->a of ƒ(x) exists if and only if given any ε > 0 there exists a δ > 0 such that ...)[1].

2. chose a function ƒ(x) such that on a given "a", ƒ(a) = ƒ(a)/0.

3. prove that the limit exists and is finite.

Now if we defined division by zero it would look like this:

Axiom: For every element x of the real numbers there exists a x' in the real numbers such that x/0 = x'

I advise you to play with this new "rule" to see if it leads to something interesting. Hint: try to prove that 1/0 = 2/0

Comments I haven't seen are a different color. But I read HN from a "custom" UI.
I should have been more careful with how I wrote my comment. I almost always get silently downvoted when I bring this point up for discussion so I was directing that "you" at those people in particular and not at you. Sorry for coming across as attacking you and thank you for caring about hn.

I don’t know the status of it, but it seemed like an interesting idea.
Nuclear isn't being swapped out for renewables in Germany, it's being replaced by gas (in the best cases).

I think what enrages people is that unlike Poland, Germany is actively going in the wrong direction. They are stopping all nuclear power, not just closing old plants. All scientific evidence points to this being a terrible decision.

There's an expectation that Germany has the means and governance able enough to avoid taking disastrous decisions when it comes to fields which are almost entirely technical and non-political. So it was a shocking development, especially coming from a conservative majority that most people would assume would be generally pro nuclear.
>>Ah. The American arrogance shines through. "Government controlling health" and "these lazy Europeans with their 150 days of vacation".

Factual statements are not arrogance.

>>This is not a safety net. It's the last resort.

My point is it should not be considered the "last resort", in fact I think people wait far far far too long to file for bankruptcy.

>>Europe has laws around bankruptcy

While true, The US is normally cited as creator of personal bankruptcy law, and it used as the benchmark. Changes in the laws in the EU has expanded personal bankruptcy but in many parts of the EU the bankruptcy laws are not as favorable to personal debtors than in the US.

>>I don't want to become poor before safety nets kick in.

Then it is no longer a safety net... It is just a universal income scheme or outright socialism.

>>I don't want to be beholden to my employer for my medical insurance.

Nor do I, which is why I support deregulation of the industry, returning to free market principles, and allowing tax exemptions for personally acquired plans instead of only when it is part of an employer plan (and a range of other reforms) instead of just believing the government should provide....

>I don't want to have only 10-14 days on average to spend time with my family or with my kids. Etc.

Great, negotiate that with your employer. People that do not have those same priorities should also be free to negotiate what they want which may include less time off. That is what a free society allows for. What you want however is to mandate your preference, believing that is what is best for "everyone"

>According to various models, it's anywhere from 30% to 45% of people, with actual numbers probably being worse

One of the reasons for that is the "safety net" system which largely punishes people for their success. If the poor attempt to climb out of poverty that system takes away benefits faster then the income is replacing those benefits, literally paying people to stay poor.

A better system then this network of misaligned "safety net" programs where the government is providing services or payments to fix specific perceived problems (housing, food, etc) would be a more generalized graduated negative income tax system that phases out as the person makes increasing income. This would have to replace all "safety net" programs, and make people individually responsible which is a negative concept in the modern world.
Liberalism in and of itself does not mean "right wing" to the world. As you would have it, the only thing disqualifying one from being a conservative is being a commie or anarchist.
What I'm saying is that to a certain level, humanity will always want to change their consciousness. This has nothing to do with suffering in the world.

Of course, suffering then leads to people seeking out quick fixes. But you know what? If you're suffering from chronic pains, and medical experts can't help you (as has been the case for many people), taking some of these drugs (like THC) is highly preferable to not having anything.

Also a cheap option that doesn't involve sharing walls. I looked into living in them because I have PTSD and hypervigilance + the lack of insulation in the buildings/apartments affordable to the poor = a living hell. And without addressing the PTSD, I couldn't have the fortitude for a job paying any better.
I have been hacking away on this for a couple of months and thought I would document the process, I'm pumped to have a small self contained project to tinker with :)
For the past decade there has here in Norway been a recurring news sensation surrounding the mountain Mannen[1] (literally "the man") located in Romsdal in the northernmost part of Western Norway. Geologists have found Mannen to be at high risk of a sudden and large-scale landslide, placing the local population at the base of the mountain at great peril. There have been several abrupt evacuations of the place over the years, whenever measurements indicate a sudden increase in risk, with great media exposure and public interest. However, The Man has still yet to fall as predicted.

A website was soon set up: "HarMannenFalt.no"[2] (Has the Man fallen?), displaying no more than the word "NEI" (No). The sentiment of the joke was felt by all, as many had grown tired of all this attention being directed at what was essentially, on its surface, just a mountain, standing there, doing nothing.

I was a student at the time, and remember many idle screens around campus set to this page, reeking of that sarcastic mock-worry only a student body could put on. But I suspect a lot of us were secretly waiting for the moment when the text would change into "JA".

And soon enough, something did in fact happen. A neighbouring mountain, Veslemannen (The Little Man), saw a considerable increase in daily movement in 2018, before finally there was a minor landslide in 2019. But this was not the landslide we had been promised and waited for, as The Man himself was still standing tall as ever. A "JA" was not really in order, but then perhaps neither was really a "NEI".

Instead, the website was updated to show "TJA", a Norwegian word somewhere between yes and no, with meaning closer to "Well, perhaps".

As an aside: A second website with identical design was also created: "HarDovreFalt.no"[3]. A play on the concept with allusion to the vow of our founding fathers: "Enige og tro inntil Dovre faller" (Agreeing and true until Dovre falls)[4]. The "NO" on this second site, I think, is far less likely to change any time soon.

That's how it is in the bigger world outside of academia... Why would it be any different?

If you want to make the full value of your work then become your own boss. Though as others in the parent thread pointed out businesses cost about .5 or so for every dollar you make.

So it's either suck it up and accept that's how our society is structured and it happens to be an annoying aspect of it. Or we try redesigning society and discover different annoying problems/issues.

You’re making an assumption here.

You’re assuming that in the experiences she had with those students, it was their politeness that she interpreted as friendship. It’s also possible that she can discern between politeness and friendship and was seeing genuine friendship.
Huberman usually interacts with other researchers. So your conceit is that most of those are right wing. Again, unsubstantiated and likely false.

What this shows is that a concrete environmental problem that directly impacts constituents can actually bypass a lot of the partisanship.

It's a lot easier to ignore climate change, since the impacts are far removed from any single direct action. But here Floridians have over the course of a generation seen a river essentially die, with a clear cause and obvious solution.

Nobody wants to destroy rivers for no gain. Rather, people are willing to destroy the environment when the benefits are evident and the costs are hidden to them (or paid by somebody elsewhere).
Alcohol consumption is proven unsafe to health[1], but it's not controversial. Adults have the right to choose risky behaviors, just like they do in fire fighting, coal mining, underwater welding, or mountain climbing. In some cases, we admire those who choose them for their bravery.

Let's not confuse "unsafe" with "controversial" or "unquestionably bad." But let's remember that "safe" has a clear definition, which does not describe current "safe use" narcotics harm reduction programs. Harm reduction by definition means that harm is involved. Someone safe from street narcotics is someone who is not using them, at least in the way that they are generally used recreationally.

I use SuperMemo https://super-memo.com/ for memorizing things. It uses spaced repetition. It has a bit of a learning curve, but once you figure it out, very effective. I feel like I have seen an article on HN about it before.
Tending to a digital garden of your own making has been the most effective for me by far. No other organization beyond that, at most hitting a random note inside a subfolder for 10-15 minutes a day.

A $100M Mess: North Carolina’s attempt to digitize court records
One thing from the article I don't really understand: why are power companies signing these shutdown deals? Are they not allowed to set quotas or cost tiers that make sense for the limited capacity they have? Why can't we have reasonable prices for residential amounts of electricity, and progressively more expensive bands that control for the actual value of that electricity based on the supply? Why cant they put an energy quota/cap for their customers? Clearly miners are valuing the electricity more than for what it could be sold at because they keep buying more of it. It sounds like we need a smart grid just to get energy economics back to something reasonable. Although the fact they can call up their client and tell them to shut it down seems like they already have something in place, but that it just needs to be automated as quota enforcement.

And I didn't see any mention of policies that could make coal-sourced electricity more costly. It seems like again, obvious economic policy would improve this situation. But it's just written as BTC = bad.
Not really.

Though researchers love to buy big expensive sample fridges or other equipment when they're ending a project and need to spend anything left over in the projects funds.

Is that waste to you?
That is if you don’t get caught at customs… you’ll have to pay at least the VAT on the value of your purchase and possible a duty as well.

So if you want to do it legally you’ll have to add 20-25% to the price which no longer makes it very appealing.

It seems that you can self host the thing. Apart from that, it seems that you would be sharing info obviously with OpenAI (both GPT and Whisper), Telegram and Google.
Is there some direct reference to Zippy and Emacs? That connection seems less likely than the extremely common and well known phrase "are we there yet?"
If you close down the old ones before building new ones, you choke the industry.

Most of our nuclear energy experts are already 50+. New generations are told that the industry is shrinking (unless you move to the forward-thinking PRC).

Also, it's better to be down for maintenance even for small issues than to play fast and loose. Nuclear safety regulations and agencies are generally well respected, and those frequent maintenance downtimes are a sign of that.

Huge fan of SRS here. Anki never really gelled with me personally. I still use it but really prefer this app called StickyStudy. It’s mostly for learning Chinese / Japanese but there was a generic version which has sadly been abandoned by the dev. It has very straightforward SRS / leitner system and a bit more simplified ui. Not my app but just wanted to share and maybe inspire someone to make a successor ;-)
As mentioned in the post, the conditional is trivially converted to a cmov or a bitwise expression. A column-oriented algorithm makes sense when the data is naturally laid out with bitpacked columns.

> This makes it very hard to catch up later on an article’s comments

My biggest complaint related to this is that all threads are dead within 24 hours, which kills a lot of interesting discussion. And commenters have no incentive to reply to dead threads.

This discourages in depth back and forth conversation which I usually find is the most interesting.

I'd be very interested to see your approach. So far, the most promising (non-NN) technique I've seen requires taking a symbolic inverse of a sparse matrix, which is just barely possible for a simplified pedal model.

I rented one for a while and it was far better than 'not great'. Only downside really was the noise from the air circulator located inside, otherwise it was pretty much a normal 3 bed 2 bath small home.
I think the major point that people miss is that there is a thing called the "Carbon Cycle"[0] which basically stipulates that all carbon that already exists in the system will continually be transformed into different things and then back into carbon (and the inverse). This is pretty ordinary and cows are a part of that. Though the effects of transforming a lot of carbon at once might be profound and dangerous.

The major issue is that we're digging up shit loads of carbon and releasing it, which is the much more dangerous thing and reframing the argument to be against meat because meat has a carbon cost is like saying that the mountains are causing water levels to rise because "water comes from the mountains" (though, as part of the water cycle).

Great work! Thanks for taking the time to build this and open sourcing it. For me, it scratches on a very real itch. I’ve toyed with the idea of a personal AI assistant to act as a second brain, and help me prioritize and remember things with human intuition (“you can’t afford to delay X, do X today and maybe reach out to Z to set the expectations for delaying Y?”).

To me, the greatest strength of LLMs is not their knowledge (which is prone to hallucination), but their ability to analyze ambiguous requests with ease and develop a sane action plan - much like a competent human.

One a side note: wouldn’t it be significantly cheaper and as effective to use ChatGPT 3.5 by default, and reserve GPT 4 for special tasks with explicit instruction (“Use GPT 4 to…”).

For most chats, GPT 4 would be incredibly wasteful (read: expensive).

Also - it would be very cool to experiment the use of GPT 3.5 and GPT 4 in the same conversation! GPT 3.5 could leverage the analysis of GPT 4 and act as the primary communication “chatbot” interface for addressing incremental requests.
The problem with this approach is that it is impossible. There is no "general chemical analyzer" that can consistently detect the quantity of a substance in any sample. You may as well suggest that a wizard uses his magic wand to purify the heroin.

Not to mention that users will begin to bring in all kinds of crap to see if they can get heroin from it — notably, their own excrement. Drug sellers likewise may decide it is unnecessary to recrystallize their products to remove solvents, since your suggestion makes no distinction between the sample contaminated with acetic anhydride and the one that was cut with mannitol. So there is still plenty of moral hazard.
Remember that there’s often the story and then the ret-conned “story.” From Wikipedia:

> Initially called Startup News or occasionally News.YC.

HN exists to serve the interests of YC. It’s a marketing/advertising tool. It’s great to believe that it’s a community, a place where interesting conversations happen, etc. (and those things may also be true) but remember what it is at its core.
Great, so instead of sharing all your data with one party, you can share it with 3+ parties
You open up a lot of conversations here not related to wealth tax. The question is, do you think it is okay for a government to say "hey, we changed our mind and the money you have that we already have taxed we want to tax again". Besides this, are you okay with keeping people in perpetual wage slavery and force people to work until death. The income tax in the US was introduced only for the rich and was only like 2%? But now the taxes is well above 50% for most Americans. It is always a slippery slope.
