Right, I did a simple calculation, for the same distance driven, both gasonine and fuel cell cars produce pretty much the same amount of water, about 100ml/km. Only difference is, with gasoline that water is mostly vapour, so it doesn't get on the road so much, fuel cell cars have small tanks not to wet the road constantly.

One core concept of PICO-8 is the artificial limit to 32 KiB per cartridge.

While that would certainly also be enforceable with PNG data chunks, I think the 32K restriction lends itself to the steganographic solution more naturally than using a chunk would.
Thank you. This is the absolute truth.

While I haven't read Freud's paper [0] myself, and I know that there are a couple of pop history/science accounts that say that [1], there are also a bunch that don't [2]. A bit of googling drags up this account by a guy who seems to have actually read the paper:

>In 1874 Dr. Syrski had announced the most recent solution. He had discovered a small lobed organ and described it as the testes of the eel. Carl Friedrich Claus, chief of the Institute for Comparative Anatomy in Vienna, assigned to his student Freud the task of checking Syrski's observations. Freud dissected 400 eels, finding the Syrski organ in many of them. On microscopic examination he found the histological structure of the organ such that it could well be an immature form of the testes, though he found no definite evidence that this was the case. [3]

Modern researchers propose that Syrski's organ is an optional precursor to the testes [4].

So the anxiety and really all parts of our psyches serve important purposes. But sleep, for instance, is possibly the most important physiological thing we do in a day. It’s also common for anxiety and the like stress responses to disrupt or even negate the possibility of sleep. So in those cases, it’s definitely worth dialing the anxiety and stress processes “back” with external aide.

That great except you haven't explained how TFL exists at all. Are all the lines privately owned and operated?

Also, as I've said before, the UK government does not care about the law. That's why we were so enthusiastic to get involved in Iraq 2. That's why we're still ignoring the ruling on prisoners voting (15 years later). The truth is, laws are just an excuse for governments about why they "can't" do things people want. Don't want to nationalise trains? Blame some obscure foreign law. Do want to play cowboy in the Middle East? Go for it!

And that's without getting into why we never bother to try and enforce all these laws ourself? If DB are an illegal state company, why not say so in court? Instead we give them contracts, because we're a law abiding country that ignores laws when awarding contracts to foreign entities but not domestic ones which is illegal!?
I am not a steel expert, but the steel industry is constantly talking about converting to hydrogen. Your sum formula has a bit lot of oxygen, shouldn't it be Fe2O3+3H2 => 2 Fe + 2 H2O?

If we are going by numbers, how many talented artists are indeed there? Of this how many are talented enough to be both artists and stock brokers AND are overwhelmed by stock broking so much that they give up on their Picasso like talents? 0.0001% of the general pop? May be if we count every one with massive world class but oppressed talents, will they account for 0.1% of the world pop?

As much as it would liberate the stuck artists et al from the above 0.1%, my theory is that it would only allow the rest 99.9% to focus their time into consumption of various things rather than production of invaluable goods.

Now we could move the goal post and say, ‘hey, they were born as human and by that they have won the lottery! Why shouldn’t everyone be eligible for the basics?’ - but that’s a different argument than saying this will liberate the arts. I don’t buy that line of argument.

>The hard part of an oil change is getting to the oil filter.

There's no standard oil filter location; in my car it's at the front of the engine and accessible just by popping the hood and removing the engine cover – no tools required (although a wrench is useful for the filter housing).

It's definitely more work to access the oil pan plug, but not so much that I'd rather schedule an appointment somewhere, drive there and wait and drive back (and pay extra for the same oil and filter).
Amazing read. Leaves me with wondering how do we make sure the sequences injected with the vaccine are exactly the same sequences that are described. Do they have some kind of verification method that there was no encoding errors and they won't inject some random sequences? Also what's the risk of this erroneous sequences to be harmful?

It seems like you are missing an important aspect of UBI: What level of income will it provide?

If a (perhaps more fulfilling or “fitting”) life on UBI is to rival that of say a stockbroker, UBI must provide more freedom than one can get by working in that position, while perhaps saving up for early retirement.

The income level will have to be moderate at the very least, to rival that. Since it is supported by tax revenue, it must be part of a balanced budget. This can quite easily be matched by a reasonable income, where a good amount is put into savings each month.

I agree, that this is not an option for a lot of people, as their monthly expenses won’t allow to save like that. But then that isn’t something that UBI will fix - given its “basic” nature. If all else equal, the higher the level of UBI, the higher the price level as demand increases.

I do support some models of UBI. It could help in replacing the myriad of different welfare programmes that are only about money here in Denmark, where billions of USD are either wasted or swallowed by bureaucracy each year.

However, I find it almost fraudulent how UBI is being misused as a “Trojan Horse” by some people and especially by politicians.

UBI, like most other insurance schemes, will only work if most people are net-positive contributors. This makes UBI mostly into a welfare programme - something that’s limited in its use.

But if the idea is that it’s something for everyone, most of the time, I’m hard pressed to answer how it will work on a societal basis, without the use of force.

I don’t believe that is what you argue for, so please don’t take this as a straw man argument against your point.

Apart from the different view you mentioned (added screenshot and top comments), I believe the other more subtle difference/advantage is that it picks up the most relevant stories on any given day, and filters out the others from previous days.

My experience around this is that when I check the latest "daily", I know from which day I can start reading, and all the stories starting from there will be new to me. Otherwise, checking the "best" stories, say, every day, I would have the added effort of filtering out the ones I've already seen.
If you believe in UBI, and you have an average US income, you can already do your own UBI scheme by donating some portion of your income to a group of people in a poor country.

This is the subject of an entire book by Neil Postman called "Amusing Ourselves To Death" (1985), including a chapter called "Teaching as an Amusing Activity".

Some excerpts from the book:

> “Dr. Ruth Westheimer is a psychologist who has a popular radio program and a nightclub act in which she informs her audiences about sex in all of its infinite variety and in language once reserved for the bedroom and street corners. She is almost as entertaining as the Reverend Billy Graham, and has been quoted as saying, “I don’t start out to be funny. But if it comes out that way, I use it. If they call me an entertainer, I say that’s great. When a professor teaches with a sense of humor, people walk away remembering.” She did not say what they remember or of what use their remembering is. But she has a point: It’s great to be an entertainer. Indeed, in America God favors all those who possess both a talent and a format to amuse, whether they be preachers, athletes, entrepreneurs, politicians, teachers or journalists. In America, the least amusing people are its professional entertainers.”

...

> “We may surmise that the ninety million Americans who watch television every night also think so. But what I am claiming here is not that television is entertaining but that it has made entertainment itself the natural format for the representation of all experience. ... The problem is not that television presents us with entertaining subject matter but that all subject matter is presented as entertaining...”

...

> “Books, it would appear, have now become an audio-visual aid; the principal carrier of the content of education is the television show, and its principal claim for a preeminent place in the curriculum is that it is entertaining.”

Yes, you are right, in 2020 Stackoverflow and other forums have taken over. Usenet is no longer relevant (not 100% true, but you get the point). Web-based forums are the places where one learns now. Also, the documentation of different software, libraries and tools has improved a lot.

I wrote that blog-post back in 2014, that was 6 years ago. I learned programming from 2005-2008 and all of that was because of the help I got from the mentioned newsgroups. There used to be a few known names on USENET and everyone knew them and ask them for help. I really loved USENET. These days comp.lang.c is mostly filled with spam and comp.object died sometime ago. Life is about change.
Actually that comment was justified, because the article says that while the quantum efficiency is around 96%, the water splitting worked with ultraviolet light having wavelengths between 350 nm and 360 nm.

Only a very small fraction of the solar light is ultraviolet light, so the usable efficiency of such a device is quite low.

While this research result is very interesting as a demonstration of what can be done, it is very unlikely that this is a path that can lead to the best way of capturing solar energy.

Either multijunction photovoltaic cells or thermal devices can capture around half of the total solar energy.

If splitting water is desired, that problem can be solved separately, using electrical or thermal energy, and it should be able to reach similarly high efficiencies as with these photocatalysts.

The combined efficiency of the 2 processes should be still far greater than the efficiency of direct water splitting, which is constrained by the lack of enough ultraviolet light in the solar spectrum.
> if you give everyone a fixed amount of money, won't the cost of things just rise accordingly?

> wouldn't it make more sense to heavily subsidise the basics?

Breaking this down a little:

Industries with monopolist practices can be expected to raise their prices to capture more of this new income. I agree, that seems likely.

In my mind, this would likely include housing/land ownership.

By proposing to subsidise housing instead, you're proposing to effectively give this money directly to landlords instead of to everyone to have their own negotiating power and make their own decision.

But, won't the cost still just rise accordingly, by your theory - won't landlords just pocket that money and demand even more?

It seems more effective to trust people with their own money.

That's probably true, except for one important category of goods that has a tendency to suck as much income from people as they can bear - housing.

It is true that with UBI people have the option to move somewhere where housing is inexpensive, but I don't think it's desirable to have people already dependent on UBI move to places with lower economic opportunity - cementing their dependence on it.

That being said, expensive housing is a problem that exists with or without UBI, even if it would interact with it in an unfortunate ways.

I feel it's a bit unfair to those mechanical components to ignore how complicated power electronics are, for example. They are perhaps less inspectable for a layperson (what happens when you break it open to see the insides?) so we tend to treat them as more of a primitive black box building block, but treat the mechanical components as complicated assemblies of primitives.
The point is that a lot of valuable work is incorrectly classified as "doing nothing" in the monetary economy.

For example caring for people who need caring for (elderly, children, disabled) is essential work that is mostly done for free. This is a lot of work collectively.

In a system that properly values essential work it would be paid, but it isn't paid because those needing care cannot pay for it, and other people and "the system" are not willing to.

But even if "the system" started targeting all forms of care work, there are countless other things which are valuable but unpaid. It seems utterly implausible that we would ever devise a system that pays for all work that is valuable, if only because people disagree about what is valuable and all the power dynamics that result in the emergent properties we see as capitalism, "the economy", etc.

In your idea, increasing the tax threshold does not solve this problem or even begin to address it. So it's not an equivalent result.

UBI does address it, by removing the power dynamics and gate-keeping for basic resources, letting people figure out themselves what is the best use of their time in each individual circumstance. The very concept of "what is valuable" gets a refresh, away from the systematic biases that emerge from centralised rule-making, power-law power structures, and the error of conflating money-value with human value when humans do not have evenly distributed access to money with which to signal what they value.

The fact a very large number of people put so much time into tiring unpaid work (such as caring), often on top of their paid jobs (if they have any time left for paid jobs, some don't and it sucks), shows that the "UBI fear" that everyone people would sit around idling their whole lives is very unlikely.

It's likely some people would still call it "doing nothing", as they do currently, but they would be wrong.

Agree with your sentiments, but a phone number isn't a unique identifier we'd care about.

Rather, it is the IMEI (general networking equivalent is a NIC MAC address). Cycling that is what is necessary, but I do not believe that is an easy thing to do - unlike DHCP, there isn't a notion of "connect to cell network, get a cell phone assigned" (for a variety of valid reasons).

A more viable approach is to attempt to severely limit the data leakage from apps and the like, but this is a hard balance to strike between app functionality (example: ride hailing app), and preventing analytics which can be performed based on the data those apps collect and, usually unbeknownst to the user, provide to the telco as part of location services.

Nobody is talking about your "ideal free market". I saw you mention it on another threads and let me make this clear: we are only talking about the regular, imperfect, free market. Free as in free of government interference, not some other ideal. Free as in everybody is free to participate.

And its not binary, either. You can have it completely free, freer, free-ish, all the way to lightly regulated, heavily regulated, planned and completely locked down.

Finally, I am not talking from economists' perspective, but from that of the regular guy on the street who is just able to see policies and their result. But my conclusion is extremely simple: the freer the market is the better everybody (other than profiteers, bureaucrats and politicians) is.
