Hydrogen is most often produced from natural gas, so...yes, it is a "primary energy"

Granted, using hydrogen produced that way isn't a win over just using natural gas.

Programmer jobs are harder to fill because programmers have a long list of personal preferences, trick questions, random algorithms to quiz your depth of understanding on, arbitrary answers and stack-specific questions in their arsenal for rejecting candidates. Everyone else focuses on what the job actually entails and how much they will be making.
Hi (Steven here) - biVector.net is an effort from active researchers from Cambridge, UPEM Paris, UVA Amsterdam, and a couple of others. (as well as the developers for some modern, actively maintained GA libraries).
It is specially only for mobile users (as currently implemented, at least)
There are three pretty clear facts

1. There is has been a sharp drop in the number of smokers

2. There is has been an even sharper jump in the number of the vapers, especially concerning among youth.

3. The available evidence says that the inherent risks of vaping are an order of magnitude less than smoking.

As a society we're discussing whats the optimal public health policy to reduce vaping and smoking. Unfortunately these are substitutes so as we crack down on the availability of one we increase consumption of the other. And this is why it's important to understand the relative risks of vaping versus smoking. If they're similarly unsafe then it doesn't really matter how hard we crack down on vaping. But if smoking is far more dangerous than vaping(which the evidence points to) then we need to be much more careful about reducing vaping availability.

> it's a double-edged sword that makes everyone think they're an expert

I did not get the impression that the author thought he was an expert. By reading, I think it’s clear the author is aware that he’s not an expert.

More generally, I don’t mind articles written by people who aren’t subject matter experts. Mainly because I think most new ideas come from outsiders.
There is a subtle technical difference in the literature, where regulation is externally imposed and codified, while communal management is devised, enforced, and most importantly, flexibly changed by those actually involved with the appropriation and management of the resource.

> I feel we reached transparency for professional analog recordings some time in the 1980s, and I would argue that this applies to analog film as well.

Not sure what you mean by 'transparency'. Either way, go back and look at an 8k scan of 'Lawrence of Arabia' or 'The Sound of Music'. The image quality is robust and resolves everything perfectly.

Even an '80s title captured on 35mm that is scanned properly will hold up against something shot on an Arri Alexa today. The 'blurry' reputation comes only from the subsequent formats like broadcast television and VHS that people caught a lot of these titles on.
>Like I said, I don't want the programmer in charge of the software that manages my financial or health records to be creative or over-deliver, quite the contrary.

Sure, but most programmers don't program systems that manage financial or health records or write the software for the ISS.

For the majority working on enterprise backoffice stuff, CDUD, web services, mobile and desktop apps, websites, and so on, being creative and over-delivering is OK, and even encouraged.

I've spent a month with uMatrix misconfigured so that it was disabled by default on websites. The internet turned into a horrific bloated mess.

How do these sites survive when it takes 30 seconds load the page (which freezes your browser) and then takes another 20 seconds to find the content hidden between creepy ads from ecommerce sites you recently visited?

Pawn transactions, not delivery transactions.

Police have access to pawn transactions and use them to investigate crimes. There's a crap ton of regulations around pawn shop transactions, they are open to the authorities.

If you note your serial number of your MacBook and your MacBook is stolen then you fill out a police report with the serial number and your MacBook then if your MacBook is sold to a pawn shop then your MacBook would be recovered.

> 3. What the hell is wrong with you idiots, safer than cigarettes is not the same as safe

I wouldn't say this to anyone who was previously addicted to cigarettes and switched to vaping as a safer alternative.

I would, however, say (a nicer version of) it to any non-smoker who wants to try vaping. And, I would push back against anyone who vapes and thinks it's safe, lest they create more people in the aforementioned category.

That last paragraph is exactly what I was thinking. Did people in ancient Greece actually believe the stories from the Odyssey or Iliad? Or was it meant to entertain? Or have a look at Genesis. Is this something that the original sources believed to happen or was it an entertaining story in the beginning and retold until people started to believe in it? I'm not sure there always is a clear distinction between fiction and religion.

The sentence "p or not p" is a tautology ("true", ⊤) in classical logic, so you can't derive anything useful from it. It can carry some power in non-classical logics, like the intuitionistic logic, where it's not true that "p or not p" for any sentence p.

You can derive anything from false, this is known as the principle of explosion: "ex falso quodlibet", "from false anything":

There are often quite a few psychiatric issues that nicotine helps out with. Also, probably a good chunk o population has issues that are just slightly below threshold of what is considered a condition, but niccotine helps them out a lot.

As an ADHD-diagnosed person, to function properly I need some sort of a stimulant. It's really "choose your adventure" kind of a situation - I need either sugar, ritalin or nicotine, and the less I take of one the more I need of another to function properly.

Keep that in mind when you see someone smoking - unless you're 100% sure that they are neurotypical, you don't know if it's addiction or self-medication.

I have to second this. Mercedes has a nice fuel cell demonstrator car, but will lease out only a few of them and no larger production is planned at this time. Other than a few projects which get shown to the press to have something new to show, there is no larger activity around hydrogen in Germany.
Seems like they're storing it in the gas network, does that not scale?

There's enough energy in the gas network today to power the world for a few days, seems like a great way to store excess renewable power.

> an attachment not just to a record, but to a specific record, which hiccups in a specific place and has a specific rip on its sleeve

My first rock album was a CD copy of Nevermind, which I found in a roadside ditch while walking home from school one day. It was so scratched up and many tracks were damaged or not playable. I listened to that broken CD for years. Opened my eyes to a whole world beyond the country I was raised with.
So what? Do we stop "young" people from eating junk food or being targeted by advertising? The risks of vaping are strongly indicated to be far less than many other recreational activities young people do (drinking and taking random drugs being one obvious thing I see in my community, that seems to still be on the increase).

And if there are extra vapers, but fewer smokers, then it seems probable everyone is way better off. Weigh a small unknown risk against a large known risk.

Out of interest: do vapers show the same physical signs of damage as smokers?

Someone who smokes significantly for say two years has clearly visible changes to their skin, and often obvious indicators of unhealthy lungs: strong indicators of long term damage effects. I don't know well enough any people that have only ever vaped for me to have a inkling about the visible side-effects of vaping (to use as a proxy for making a guess at long term damage compared to smoking).

That was just the first link, I'm sure there are more, but i'm not going to do your homework for you.
Supercritical CO2 is a (very non-polar) solvent. I can't imagine what would make that a physical or mechanical extraction.

Good CO2 extraction uses two passes at different pressures. One to extract the terpenes and one for the cannibinoids.
Google Ads can be implemented in a reasonable way. It doesn't need to be a horrible experience. Greed has made them integrate 5000 other networks and they're the reason adblock is on the rise. I'd wager display ads would have much better return if they weren't abused for years.

That being said, it is the fault of these publishers to under invest in developers. It's like not investing in the printing press.

I don't think I have a copy any more. If I do, it's likely in a format for an old MOD tracker that I may not be able to open any more.
Does it? It seems like it would still be more efficient to just use swappable battery packs. IIRC hydrogen is either made by cracking natural gas (which puts out carbon), or it's made extremely inefficiently via electrolysis (in which case you waste much more electricity than you would by charging batteries). The former is more economical than the latter, but doesn't seem to have much in the way of environmental benefits AFAICT vs. just using the nat gas directly.
There is about 9gW of peak nuclear power left in Germany. That is a valuable contribution to keep the CO2-mix in the grid low. Using it for electrolysis would be way less efficient than other forms of storage.

For the record, I get this all the time in my work and it's super frustrating that none of the "science or stats languages" (with the possible exception of SAS of all things) natively support multiple types of nil/missing data.

I often need not applicable, unknown, unsupplied, zero types, other, undefined/ nonsense/error, theoretically knowable but not currently present, missing, etc, depending on the context.
Never works for me, but maybe you navigate the structure of the organization better? For instance, when I changed cable companies last, the ‘retention’ department stooge was dopey, didn’t know anything, and couldn’t offer anything. Whereas the sales person for the company I switched to was sharp, quick, ready to discuss options, and made me an offer.

And as I recall, I had put a block on my credit report, so it took a few calls to the sales agents to close the deal. Each one was equally willing to deal, but then again, each time I called back I had to give more to get the same deal (1 year to 3 year, 100$ product gift certificate gone, and finally no free installation—uuug! They said I had the GC, but it never showed up. I called, they stalled, whatever)
I found vinyl a bit annoying in college--but that was probably because as the only person at my end of the hallway who didn't smoke marijuana I kept getting asked by people to handle operate their turntables when they wanted to listen to music while high.

> to make having children more attractive with government subsidies and labor laws

This is a bad idea. Russian government have already tried that, and the result was that less wealthy people (mostly alcoholic and drug addicts) started to literally make children to receive subsidies and spend them on themselves.

It's fun to me how Google search results differ for "to make a child for subsidies" and for this same phrase translated to Russian, where it has already became a phenomenon.
Sure, but the fact remains that by sending you to an ER instead of a GP's office caused an increase in cost to everybody in your risk pool. It's an inefficiency that shouldn't exist.

Actually, most planets don't have plate tectonics, (and what is the probability of a dinosaur extinction event?) So their population is "first generation", and they basically don't have fossil fuels. So no industrial age, and no powerful ergols for rockets. When we'll get there, we'll find mostly Star Gate-like civilizations: non-technological civilisations with lots of slaves and manual work.
Cassettes were also the first and last audio storage medium where mainstream consumers could purchase an affordable, ready-made appliance for home listening that could also act as an audio editing system, recording the result onto another cassette. This is what enabled mixtapes.

With formats that came later, CD-recording remained expensive until personal computers were becoming widespread, and while CDs could be ripped or mp3s could be remixed on computers, you needed software that was often commercial and rarely included.

Digital audio then de-emphasized removable storage, re-introducing friction between exchanging music and listening to it on a portable player. Nowadays, most music exchange happens online, but the appeal of exchanging music in person endures even for generations that grew up with the Internet.

Cassettes had excellent usability for sharing: ease of duplication, ease of remixing, more rugged than vinyl, easier to hold than CDs, and maintaining its playback position at rest [1]. Couple that with authentic nostalgia, or yearning for an aesthetic and mood of times past. While the vinyl revival is centered around the deliberate experience of browsing, playback, and large-size album art, like enjoying an artisanal product made by skilled craftsmen, cassette revival celebrates the versatility of the format, its lack of restrictions, the opportunities for creativity, and its physicality on a very human scale.

No doubt many specific problems could be addressed by work on the tragedy of the commons.

But at the same time, theories around a healthy market _require_ defection in order to "guarantee" competition. So in its rawest form, we have an economic system that requires a system that is known to produce some bad outcomes (climate change) in order to avoid other bad outcomes (collusion). This poses large systemic challenge indeed.
No, because you're assuming a zero-sum game or even profits. It's widely known that these e-scooter companies are eating a ton of losses right now as they figure things out.
They later mention Bottom and get into some discussion of a null value vs. an empty type.

Interestingly, Haskell also has Data.Void.
>Interestingly enough, the optimum solution is always present when N=1. If there’s just one actor (you) then you’re not likely to destroy your own property.

Two objections:

1) Who said one person would necessarily understand it as "[his] own property"? Unless it is truly their property (e.g. their own house), it's conceivable that a single person could still consider the place they are in expendable (because e.g. they could move elsewhere, or they care more for short term profit for it and don't consider long term issues from their behavior).

2) Even worse, who said people respect their own property that much? People can't respect their own bodies (sedentary lifestyles, obesity, junk food, etc), their own families (domestic abuse, cheating, etc.), their own houses (tons of neglected, broken down houses), or even their personal lives (from alcoholism and drugs, to all kinds of subtler self-sabotage)...
Toward minimizing defection, the article offers these example solutions:

> What if unions gave perks to employees including job references, health benefits, etc BUT to participate in the union you had to put forth a $5k bond. This could be deducted slowly over time from your paycheck.

> ...

> Consumers could do something similar for corporations as well. Have reserved payments given out over time but only if the companies don’t create any externalities for which the consumer doesn’t approve.

There are multiple practical problems with these approaches, which might be grouped into two broad categories:

1. How do you prevent collusion? I defect and pay you to keep quiet. Or I pay you to falsely accuse another member of having defected.

2. What due process determines whether defection has occurred?

In the constrained world of a system like Bitcoin, this can be easy, but only if the outside world doesn't enter. The minute we start invoking oracles to inject external state, then the entire system begins to revolve around how to prevent the same kinds of collusion/misrepresentation behaviors in the oracles.
