The recipe:

DR. CRONK'S SARSAPARILLA BEER.

Take 1 lb. of sasafras, 4 lbs of sarsaparilla, 2 lbs. hops, 1 lb. of camomile blows, 1 lb. of cinnamon, 5 lbs. of ginger, 1 pint of extract of sarsaparilla, boil them all together two hours; have ready steeped half a pound of green tea, which add, then strain into a vat or tub, and add ten galls. of molasses, and 100 galls of water. Stir in thoroughly 1 quart of yeast, and scent to suit your taste; let stand until fermented, then bottle for use.

Search google books for "Dr. Cronks sarsaparilla beer" and it's in "Hand Book of Practical Receipts, or Useful Hints in Every Day Life", by "An American Gentleman and a Lady" on p. 34. (via https://twitter.com/JNerissa/status/1275321511646126080 )

VT program was full in 6 days and they think it wasn't worth it. This article is misleading in saying it was a cash payment. In reality VT's program was reimbursement, and they realized the people using it were going to move there anyway and had the means to pay for it, so now they wonder the value of it.

Maybe the competition will make the cash payments worth it? There are probably better ways than cash payments in mast/all circumstances though.
I used to drive a hydrogen car once in a while a few years ago. It was nice to fill the car in a few minutes and get about 300km of range, but that was it.

With the hydrogen you have so few refueling stations, they are very expensive, that range anxiety is a thing. To not improve things, reliability is very poor. My work had a hydrogen refueling station on its parking. It was often broken and actually a bit scary to walk past it. They eventually removed it, which was a good call. Another hydrogen station sharing the same design exploded a few months later. The hydrogen car sales dropped from not much to virtually zero since in the country.

So to resume, hydrogen cars are expensive, refueling stations are expensive, the energy is expensive.

Electric cars with large batteries are a much better solution to hydrogen cars IMHO. You can charge everywhere, the eletric grid is very will developped, the energy is cheap. The cars are also much more powerful thanks to the large batteries pack, it's useless but it feels nice.
Back in the 1970's it was plain to see that a Nixon initiative such as a drug war was not congruous with a free country in the same way that an absolute prohibition on alcohol was not.

The first Nixon election was actually the birth of the monster which enabled such a multi-generation debacle.

Regardless of how toxic and harmful alcohol and drugs have been for millennia.

Turns out Nixon was not only misinformed, he also had a crooked streak.

History shows that the Reagan mishandling of a free country occurred afterward.

I not only witnessed all of this first hand, it has been a painful experience.

You should have seen what a free country was like beforehand.
The web is partly broken due to the sheer expanse of it. The author of the article alludes to how they enjoys looking at the aggregator, and notes they can always find something interesting. If Gemini ever became as popular as the web, that would stop being true.

So the selling point of Gemini is that by staying rudimentary, it can limit it's appeal, and subsequently stay unpopular enough to be more like "The Old Web". I think that's worth noting, because you could get trapped into thinking this is a technology problem, but it's really a people problem.
Hydrogen has an efficiency problem. You need to convert other forms of energy to hydrogen at a loss. Then you need to store it and transport it, which is costly and may impose quite some energy cost for cooling or compression. Then you need to convert it back to electricity, also at a loss. If you start at electricity, the electrical grid and batteries would be much more efficient. If you start at oil or gas, you could use convention ICEs and get comparable overall efficiencies. For them transport and delivery is a solved problem.

Hydrogen fuel cells are clean where you use them. But so are batteries. Inner cities could be kept cleaner using either. Inner city traffic is mostly short range, so batteries are at an advantage.

Batteries have a rare earth problem. But so do Hydrogen fuel cells. There is work to reduce it for both technologies.

Hydrogen fuel cells have a problem with varying loads. You would use additional batteries in cars to supply peak demand when accelerating or store braking energy. For comparable weight, range, and price you could replace all hydrogen technology with more batteries. Those bigger batteries would also wear out slower because the power demand per cell is lower.

So, when would hydrogen make sense? I think only if you don't care for efficiency. When you have so much electrical power that it costs you nothing and is available at least a few hours every night. Hydrogen would do well in a combination with large scale nuclear fission/fusion. It could take decades until we get there if we ever go that route.

I see that, as batteries become less and less expensive, the niche where Hydrogen could have good advantage is getting smaller and smaller. However you twist and turn it, either oil&gas or batteries have the advantage.
Similar to Europe.

I read the premise of that book and it doesn't square with what I know about rich people from personal experiences with them.

What I've learned is that money is a multiplier for personality and if you have a humble personality, then you'll stay humble while you're rich (with some caveats about people that are not truly humble).
In the context of HAM radio transmissions, encryption includes voice scrambling methods that we wouldn't nowadays consider secure encryption. There used to be a lot of analogue voice scramblers and voice inversion tools. I think you can still buy them. Generally, there is a prohibition against obscuring transmissions on HAM radio. (Or at least I think so, I'm not a HAM operator myself.)
It’s almost as if you don’t need to be filthy rich, standing on the shoulders of the poor like in America to have an acceptable quality of life in Europe due to social programs that make sure everyone has what they need.
Buy ? They not even negotiated contracts ! This just boils down to utter stupidity. Even China negotiated theirs contracts with same company.

Build ? I wonder: why Dijkstra and rest just moved to US ? Looks like since 60's nothing substantial was build on Old Continent.

O, btw: EU announced EU's own CPU - they just licensed ARM from UK :>>>>

Seriously there is need for even better "investigation", looks like all that 4-years plans/projects are just pure scam. Last one: EU own cloud, where it is ?
No. To get the same amount of quality in india you’ll be paying roughly the same - and then have cultural and timezone barriers.
Your Michelin starred restaurants are doing alright compared to which country? Many countries are doing better than the US there, both per capita and even absolute.
sounds like Iceland would do well to export hydrogen from electrolysis
Main points:

1. The only hydrogen produced from electricity is ecological. Carbon capture doesn’t work today.

2. The hydrogen from electricity is expensive, though as wind and solar get exponential cheaper, we will end up with spikes excess cheap electricity (negative prices today or disconnecting plants). It makes sense to produce hydrogen during those spikes.

3. Cars on hydrogen don’t make sense at all. The massive cost of infrastructure plus batteries are superior and getting better on that front.

4. Hydrogen from electricity can replace the first reformation from natural gas.

5. Next promising use cases are industrial heating, such as steel production (instead of coal).

6. Least profitable, but still plausible, uses hydrogen as long-term energy storage and mixing it with natural gas.

7. I wonder whether generating hydrogen from seawater and getting back freshwater would improve the economics of this form of energy storage.
How is that different from criticism of BEVs when they’re used in areas with coal-based electricity?
This article looks like a fine discussion about the economics of hydrogen production, but unless I've missed something it skips over the immense storage difficulty.

Hydrogen is a difficult thing to manage in quantity. Its density is fantastically low, so storing it in gas form requires absurd pressures -- an inherent risk to any vehicle. Storing it in liquid form goes a long way towards solving the density/pressure problem, but now the system must have a full cryogenic process to keep the hydrogen liquified. (Worse yet: over time hydrogen embrittles (https://en.wikipedia.org/wiki/Hydrogen_embrittlement) metals, making storage even more complicated)

This isn't much different than the problems faced by rockets, and it's why liquid hydrogen is not considered a 'storable propellant' for long-duration flight.

In a zero-net-carbon economy, residual demand for high power density may still have to be filled by some kind of bio-derived or synthetic hydrocarbon.
That doesn't work, because posts with zero upvotes get the same screen space and framing as posts with 25k upvotes.

This is an editorial issue, because those upvotes are decorative. They suggest a post has more reach and engagement, and perhaps is more entertaining. But not that it has more objective credibility - which is of course a reflection of Facebook's preference for promoting the former over the latter.

Voting isn't the answer. There may not be a community-sourced answer, because any system you imagine can be gamed by any more or less organised adversary.

The only workable solution is manual moderation with some attention to tone and content, and the banning of those who consistently troll.
I don't think most people consider it an energy source, more so a battery or storage medium. And cheaper storage is an important part of the renewables story because local supply can be unpredictable.

I saw this article earlier today along those lines: https://www.smh.com.au/environment/climate-change/alchemy-of...

Supposedly this stores hydrogen metal hydrides cheaper than lithium batteries, whatever that means, but I'm not qualified to judge.
When one of my comments get downvoted, I usually reread it trying to figure out why. Quite often, I realise I didn't explain my point very well and add some better explanation. That usually stops the downvotes and adds some upvotes.

On very rare occasions, I make a point that turned out to be just wrong and not salvageable in any way. If it lead to an interesting discussion, I leave it in place because it still provides context to that discussion, and I admit I'm wrong in another comment.
Good point, but I doubt there will be any kind of meaningful adoption, I think the effort would be better spent modding chromium or such like to strip out crap from existing websites rather than creating a new client-server protocol.
I’ve turned to canceling their accounts and responding with pretty harsh messages implying the person using my address is a moron who can’t type his own address. It’s not very nice but a lot more successful in getting them to quit entering my address, being nice just results in some half hearted apologies while the behavior continues.
What about health care costs? A big difference in much of the eu is that a health emergency won't bankrupt you.
If you need to the option to give someone temporary access it seems like a good option. I don't think it would add anything to my personal stuff since there's no reason I can think of to give someone else access. At work definitely.
People are downvoting the other response, but it's absolutely correct. You can't hire 1:1 between the US and India and get the same quality for less money. You can try, but it won't end well.
IRIX was my favourite UNIX flavour in the 1990s. As a result, I was tempted to try MaXX out after reading this post for purely nostalgic reasons. I keep an SGI Fuel in my basement (running IRIX 6.5.30 and everything from Nekochan) for when I need a nostalgia kick.

However, after thinking about whether I'd actually use MaXX over GNOME for a few minutes, I decided that there was no compelling reason to do so other than nostalgia.

Has anyone tried this out and decided to use it as their daily desktop? If so, I'm interested to hear your experiences and rationale. Cheers!
Do you have a source I can look at or do I have to go look at at or can you point to code by chance?

I'm quite surprised I wasn't aware of this if this is actually how it is implemented, the leading zeroes seemed right (and the difficulty by factor of 2 also!)

Thanks!
the focus of the project seems not to be on differential privacy as used by private companies but by scientists. in many cases you can't (US Census, medical records) or wouldn't want to (public health research) stop collecting the data. and allowing privacy-preserving statistical queries from outside researchers has the potential to be very useful.

What is your opinion of Toyota’s hydrogen storage system for cars? It seems to tick all the boxes.

(I just assume Toyota isn’t going big on the Mirai for the same reason Ford and GM still only pay lip-service to BEVs: they don’t want to upset their dealer network too much)
Not to be a jerk, but this seems like a really inappropriate venue to discuss operational details like this. Especially capabilities/vulnerabilities that, if they do exist, would be classified and concerning a location where the US still conducts military operations.
Bwahaha. Yeah let’s see how that works out. Looking forward to a dead company in 3... 2... 1...
I did watch the first video in full; the other link, and three others in another post only address blood oxygen. I made no claims about CO2.

I don't think wearing a mask will meaningfully affect the breathing of most people, but blood oxygen isn't meaningful in demonstrating as much.

Passing out from hyperventilation is a second order effect of hypocapnia; the proximate cause is cerebral hypoxia, despite the blood being saturated.
It's cool and interesting application of the technology, but doesn't really
seem to be practical.

When you're unable to access machine using your standard SSH keys usually
it means that it's highly unlikely that it will be possible to login remotely

As an emergency login there are two common options:

* in case of cloud: use remote VM console provided by the hosting provider.

* in case of bare-metal: use IPMI to access machine console directly.
I've sometimes wondered about a lifetime upvote/downvote counter as an alternative to upvote karma.

This would work in a secure community, but it will stop working as soon as astroturfing PR firms and state troll farms move in, because on most sites it's trivially easy to create downvotes bots to attack specific names.

Agreed, but like I’ve said elsewhere the effort would be better spent modifying an existing browser to be lightweight. That would gain more widespread adoption than a whole new client-server protocol. You’d also gain the benefit of better interoperability with screen readers and such like.
> Just try to escape your own.

I'd tell Marcus:

> It’s silly to try to escape

And there's a kicker lurking in that direction: trying to "escape escaping" won't be any smoother ride, just one meagre step closer to infinity.

Do you mean Dungeons & Dragons specifically or are you including the Satanic Panic in that phrasing?
When i was living in italy, most of my local friends were “poor” (no money) but they had everything they need - they were not even trying to become richer. A different idea of “personal success”, i guessed.
It's not possible to reliably anonymize data and still be able to infer something from it, the idea is just too logically broken. Because the whole reason for anonymity is to make sure no information about any individual or a set of individuals of the size decided by those seeking such protection can be inferred from the data by the parties that want to infer something from it. While "differential privacy" assumes that not being able to infer information about relatively small sized sets of individuals decided by the parties who want to infer something from the data is "privacy". It isn't of course, it's a pretty dystopian use of the word privacy. Hence why corporations love this stuff, privacy without privacy is godsent to them.

The article does talk about steam reforming vs steam reforming + carbon capture vs electrolysis of water and the carbon cost and economics of each.
You are not wrong overall but the mindset is changing. It wil take many years though due to the systematic and cultural norms. Most Indians are taught to do "service" instead of "innovate" because it has been a poor country with tons of competition for good jobs. Only in the last decade or so, the younger generation is realizing that innovation is important and even though the Govt. is mostly inept in encouraging this, I have seen first hand how the kids think these days and it is a good start. With more people moving into the Middle class, their access to resources is improving as well. May takes decades though.
I enjoyed reading this comment. The way you write is fun.
We use Cuelang instead for many many reasons, 'cue export' provides sophisticated merging and correctness guarantees. 'cue import' will turn existing config / schema formats to Cue and if you are really adventures, try cue get to do the same to Go
Hydrogen might make some sense for long haul trucks. Then you need fewer refueling stations on only the major routes. You could also generate the hydrogen locally by using electricity.

Alternatively you could equip the trucks with batteries and connect them to the electrical grid via overhead lines similar to trains for recharging. Combined with autonomous driving those trucks could go non-stop and leave the highway with full batteries.
> Every year America spends about $5,000 more per person on health care than other rich countries do. Yet its people are not any healthier.

I think part of the reason Americans spend more on healthcare is precisely because they're unhealthy. According to the American CDC the obesity rate has reached a staggering 42.4% of adults[0], which brings with it a slew of health problems. This accounts for an additional $147 billion in healthcare spending, or $1,429 per person (with obesity).

I think article missed a really large sector which uses coal and produces millions of tons of co2 each year, That is cement industry. Heating clinker to produce cement is energy intensive long process, where big investments towards technology for using Hydrogen can be fruitful.
> Everyone hates pharmaceutical firms, but their share of health-care rent-seeking is relatively trivial, especially once you include the many midsized and small firms that are investing heavily.

This article misses the point.

People hate pharmaceuticals because of ridiculously high drug costs, and that's about it. If they can't produce drugs at profit without gouging potential end users then it should be nationalized or subsidized.

Eventually more people will be moving out of cities after enough of them enforce one too many rules to appease some people. Obviously, not everyone will, but it rules like this seem counter to what the global system wants, which is to cram people into cities.
Witch burning, guilty until proven innocent, accuser always believed, now why does all that sound so familiar?
Indians are not stupid. They understand market dynamics as well as anyone. At best you will get a 5% markdown, and instant flight once a 4% markdown opportunity comes up. This is not enough to cover for the many downsides to outsourcing.
I don’t know if you had access to the whole article but it addresses all of the points you mention (except 7).
The issue of charging was also there with BEVs, until Tesla straight up built a huge network of superchargers. The players in hydrogen say they will do the same. But for personal vehicles, hydrogen won't math out, it's greatest advantage is its energy density for trucks.

It's for long range trucks that we will see hydrogen first. Green hydrogen will act as energy storage, big renewables grids can dump excess into green hydrogen and thus avoid curtailment. Then, you replace heavy duty trucks, which need to be able to not have heavy batteries, with fuel cell trucks, and you build out 1000 large hydrogen stations across the transit network.
1 kg of (electrically produced) hydrogen costs more than 1000 gallons of desal.

I found my Walkman, a WMF-100 from 1988 or '89, last year while going through a box of stuff I had saved:

It's in very used shape, the battery leaked and the face plate with the tuning frequency is loose. I remember buying it at Crazy Eddie's in NJ to replace the yellow sports walkman I managed to destroy.
Good for India if it works out, I guess.

But it feels - to my uninformed biased mind - like more of Uber flailing around while slowly failing.

> Could a successful outsourcing project by Uber threaten all SV tech jobs?

No.

It could be part of some downward pressure at worst.

Outsourcing to India has gone on for 2-3 decades. It's not some new disruptive thing.
Uber is on top of a death spiral with covid, the kill lift strategy by being unprofitable not working, softbank...

From the engineering point of view Uber is done. The self driving automation is probably not possible in the next x years. It has a working successful product probably too many developers now working on non-core projects.

Moving it to India they can keep the same numbers employed reduce costs and probably throw away things created there anyways.

My guess is a key lean operations team will remain in sf. Ensuring the system runs and is updated. Self driving research can be done India.. UI screens will be local.
You missed the fact that the cpe nat gateway according to the article limited that root access to a particular non-routed IP. So, first you've got to hack that machine at Telia.
And you always have full (trip) range every morning with an EV. Yes, filling up in 5 minutes is better than 20. Never needing to fill up is even better.
Wouldn't it only be fair for us to be handing more jobs to those with greater need in countries like India? Share the wealth, right?
This was so interesting I posted it to HN now. Often when I do someone has already done so and my posting becomes an upvote, but not this time.
Never used IRIX, but I genuinely really like the icon set in that first screenshot. Also, SGI Screen is still one of my favorite fixed width fonts.

Also I think FVWM was heavily inspired from this, and I’ve used that as a very efficient UI over VNC (gradients, images, rounded corners, etc. are expensive in terms of bandwidth. The minimalist aesthetic of this interface conveys a lot of structure in little data).

The article didn't touch on this at all, so has anyone heard updates on attempts at doing in-vehicle hydrogen production from water and some sort of reactant? It's been years since I saw something on it, but if I recall, it used some pellets made of certain metals that react with the water to produce hydrogen. You'd fill the tank with water, and after some number of fill ups you'd also need to replenish the pellets which could be sent off for recycling.

Edit: I found an article about this. It appears to have been developed by the military and has been licensed out for more development: https://techxplore.com/news/2019-07-h2-power-hydrogen-fuel-s...
I don't. Isolation simply doesn't bother me very much.
